Roy. 8vo, PpP- 3! 58 Recent Literature. [January, If anything is wanting in the pages of the book before us, it is facts bearing on the psychology of these animals, such as are to be found in Morgan’s work on the beaver. Studies of this kind have, however, to be mostly carried on with animals kept in con- finement. Regarding the change of color in the winter and summer pel- age, Dr. Merriam has a good deal to say, as we have shown in a previous notice of the early part of this work, which originally appeared in the Transactions of the Linnæan Society of New York. Under the head of the varying hare the’ subject is again taken up, and the author insists that the change of color is due to the presence or absence of snow, or in his own words: “ Both in spring and fall the time of the change seems to be governed by the presence or absence of snow, and is not affected by the tem- perature.” A careful, detailed and comparative study of this sub- ject is much needed. So far as we have looked into the matter, we have been disposed to consider Dr. Merriam’s views with favor, but have learned from hunters facts which seem to show that temperature is not wholly without influence in producing the change. But why should not all of our northern mammals - which do not hibernate, but are abroad when the snow is on the ground change their pelage? Why are the varying hare, ermine, arctic fox, etc., the only animals which change? Why do not the fisher and mink change as well as the ermine ? Whether the lay reader will be pleased with the use of the tri- nomial nomenclature remains to be seen. Perhaps occasionally useful in a strictly scientific treatise, why should not Scinropterus volucella hudsonius, read Sciuropterus volucella var. hudsonius ; the uninitiated reader would then understand that a well recognized variety of the ordinary more southern flying squirrel was meant. It is to be hoped that our trinomialists will not “run the thing into the ground.” e find no occasion for criticism in this admirable book, and excerpt some paragraphs concerning topics which appear new and fresh, though for that matter the entire volume smacks of out-of- door life, is redolent of the spruce and pine woods, and carries us back to the clear skies and sylvan retreats and mountain lakes of the noble Adirondack forests, Speaking of the mole Dr. Merriam writes: “The modification of structure that adapts this animal to its cartilaginous snout, and unencumbered with external ears or eyes to catch the dirt, constitutes an effective wedge in forcing its way and stout claws, supply the means by which the motive power is applied, and serve to force the earth away laterally to admit the 1885.] Recent Literature. 59 wedge-like head ; while the apparent absence of neck, due to the enormous development of muscles in connection with the shoul- der-girdle, the retention of the entire arm and forearm within the skin, the short and compact body, and the covering of soft, short and glossy fur tend to decrease to a minimum the frictional resist- ance against the solid medium through which it moves. In fact, it presents a most extraordinary model of a machine adapted for rapid and continued progress through the earth. “The mole does not, and cannot, dig a hole in the same sense as other mammals that engage in this occupation, either in the construction of burrows or in the pursuit of prey. When a fox or a woodchuck digs into the ground the anterior extremities are brought forward, downward and backward, the plane of motion being almost vertical; while the mole, on the other hand, in making its excavations carries its hand forward, outward and backward, so that the plane of motion is nearly horizontal. The movement is almost precisely like that of a man in the act of swimming, and the simile is still closer from the fact that the mole brings the backs of his hands together in carrying them for- ward, always keeping the palmar surface outward and the thumbs below. Indeed, when taken from the earth and placed upona hard floor, it does not tread upon the palmar aspect of its fore- feet as other animals do, but runs along on the sides of its thumbs, with the broad hands turned up edgewise.” Regarding the migratory habits of the gray squirrel, which have become almost a matter of tradition, the author writes : “The minor migratory movements of this species occur with more or less regularity from year to year, but on so small a scale as to escape general notice. They must not be confounded with the great migrations, not rare in former times, when these ani- mals, actuated by some unknown influence, congregated in vast armies and moved over the land, crossing open prairies, climbing rugged mountains and swimming lakes and rivers that lay in their path. Though hundreds, and sometimes thousands, per- ished by the way, the multitude moved on, devouring the nuts that grew in the forests through which they passed, and devas- tating the grain fields of the farmer along the route. Though these remarkable expeditions have been known and commented upon for many years, yet our knowledge of them is limited almost to the recognition of the fact of their existence. Scarcity of food very probably gives rise to the disquieting impulse that prompts them to leave their homes, but the true motives that operate in drawing them together, and in determining the direc- tion and distance of their journeys are as little understood to-day as they were béfore the discovery of the continent on which they dwell. “In the year 1749 they invaded Pennsylvania in such vast hosts as to endanger the crops of the entire inhabited portion of 60 Recent Literature. [January, the State, and a reward of three pence a head was offered for their destruction. This necessitated the payment of eight thou- sand pounds sterling (640,000 individuals having been killed) which so depleted the treasury that the premium was decreased one-half.” The book is readable throughout, and its carefully prepared biographical sketches will have a permanent interest. Gray’s SYNOPTICAL Fiora.’—Everything .from the pen of Dr. Gray is welcomed by the botanists of the country as a contribu- tion from one who is a master. A few years ago a volume appeared bearing the title Synoptical Flora, which covered the ground of the Gamopetalz after Composite. The volume before us, which closely resembles its predecessor, includes the gamo- petalous orders Caprifoliacee, Rubiacez, Valerianacez, Dipsacee and Composite. The two volumes thus cover the whole of the North American Gamopetalz, and bring our knowledge of this great group down to the present. It may be interesting to give here in concise form some of the results brought out by this volume. By taking Bentham and ooker’s Genera Plantarum and comparing our North American composite flora with the composite flora of the world, we find that we have representatives of eleven of the thirteen tribes into which the order is now divided. We have 235 genera out of 766, or about thirty per cent of the whole. Our species (nearly 1500) constitute about four per cent of the whole. - we look over the tribes we find the per cent of North American genera and species to be as follows: Per cent of genera,| Per cent of species.

ALLEN’s Human AnAtomy.—This work, the issue of the first part of which was noticed in this magazine, is now completed by the appearance of Section vi, which treats of the organs of sense, organs of digestion and genito- urinary organs. This part alone contains a hundred and sixteen wood-cuts and sixteen full-page engravings. It need scarcely be said that full justice is done to the various organs mentioned in the title page, but it may be added that a chapter is devoted to the superficial and topographi- cal anatomy of the various parts of the body, and another most interesting one to embryology and the study of malformations— a subject to which Dr. Allen has given considerable study. The illustrations are so drawn as to be especially clear to the student. RECENT Books AND PAMPHLETS. Shields, C. W.—The order of the sciences. New York, 1882. From the author. Wright, R.

N., has recently un- . dertaken a journey inland from Mombasa, among the Wa-duruma and the Wa-teita, both of whom live in great dread of the Masai, who steal all the cattle they find, and kill their owners. The Wa-teita are rather undersized and are said to be very lazy, yet they live on mountain sides and summits, and cultivate the ground at the foot. The women do all the work, and carry fire- wood, utensils, etc., to the mountain top. Ndara, 4800 feet high, has a Wa-teita village at the top. This tribe are great robbers, but as they are armed only with bows and" poisoned arrows, in- stead of spear, shield, and sword, they are always defeated by the Masai. Kasigao (5185 feet), has a village at 1500 feet elevation. In time of drought the natives of this part of the country sell their children as slaves to the coast people, but always redeem them in a favorable season. Although barbarous in their deal- ings with each other, they seem to have a horror of the regular slave trade as carried on by slave-dealing caravans.——Mr. O. Neill has discovered a lake (Lake Chiuta) to the north of Lake Shirwa, south of Nyassa. The climate of the highlands of this district (east of the Shiré) is said by Capt. Foot to be well suited to European constitutions, and adapted to wheat, oats, European vegetables, and coffee-——Lake Nyassa is becoming a busy inland sea. Two steamers ply upon it, and one upon the river Shire. There have been difficulties with the Makololo, owing to the death of their Chief Chipatula at the hands of an English ele- phant-hunter, but these seem likely to be settled by the efforts of Capt. Foot. On Lake Tanganyika there are now three steamers. The African Lakes Company has ten depots between Quillimane and Malawanda, on Nyassa, and from this point a practicable road has been carried to Pambete, on Tanganyika———E. A.

A map of the Lower Congo, issued by the International Association in July, 1883, shows the river as flowing 100 miles more to the west than it is marked in the best recent atlases. Gen. J. H. Lefroi, in his presidential address to the geographical section of the British As- sociation, stated that Dr. Pogge’s account of the kingdom of the Muato Yanvo (not yet translated) proved that the people were much in advance of their cannibal neighbors of Kauanda. They practice circumcision, and are a fine warlike race, but addicted to slave-hunting. Since Dr, Pogge’s visit Muata Yanvo has been deposed and poisoned by the “ Lukokesha,” or second in authority in the kingdom, who is one of his half-sisters. The Muata Yanvo is chosen principally by the Lukokesha, but must be a son of the former king. The Proceedings of the Royal Geographical Society for October give a list of 120 stations occu- pied by Europeans in Central Africa in 1884, with their latitude — and longitude. Sixty-one of these are situated between the Equator and the Zambezi, east of 25° E. long., and fifty-nine west of longitude 25° E., between the equator and the Kuimén or Cunené. Twenty-six of the latter belong to the Belgian Inter- national Association, which has also four stations east of long. 26° E Through the letter of recommendation given by Sir John Kirk (British Agent at Zanzibar), who is in high favor with King Mandala, the ruler of Chagga, Mr. H. H. Johnston and his party are fed and clothed entirely at the cost of that poten- tate, who has given him a spot up the mountain (Kilimandjaro) where he can build a house and carry on his natural history work.—tThe Rev. W. P. Johnson has communicated to the Royal Geographical Society the result of seven years travels among the various tribes who inhabit the district east of Lake Nyassa, watered by the Lujenda and Rovuma and their tributaries. These streams rise east of the mountains which border the lake, and uniting in about 38° 10’ E. Long., flow to the Indian ocean. The district watered by them appears to be thickly peopled by settled and intelligent tribes, but the Gwangwara, a Zulu tribe that were driven northward about 30 years ago, oppress and enslave them, and the slave trade flourishes. The mountains do not ex- ceed 4000 feet in height. AMERICAN NotEs.—Dr. C. v. den Steinen, a member of the German expedition to South Georgia, has recently descended the before unexplored Xingu to its junction with the Amazons. Another German traveler, Dr. G.

The Danish gunboat 7y//a has returned to Orkney from a successful expedition of four months’ duration, during which a scientific exploration of the inland glaciers of Greenland was effected, and meteorological observations taken along the coast as far north as 70° N. lat. Much dredging aad trawling was done, the former to a depth of goo fathoms, and many unknown species were obtained. A new island, in the form of a rounded flattened cone of considerable size, was seen on July 26 by the lighthouse-keeper at Cape Reykjanes, the south-west point of Iceland. Several earthquake shocks had been felt during the preceding days. A large part of one side of the cone has since slipped or fallen down into the sea. Mr. Whitely contributes to the Proceedings of the Royal Geographi- _ cal Society an account of his journey to the foot of the flat- topped mountains, Roraima and Kukenam, in British Guiana. He reckons the direct vertical sides of the latter (above the slop- ing part) at 1090 feet, and declares that its ascent seems impos- sible except by balloon. The vertical part of the Roraima seems rather less, and there is a break by which ascent may be possible. A report of considerable interest has been received from the Danish: Expedition to East Greenland, dated Namortalik, March, 1884. Namortalik has thirty turf-covered houses, including a brewery and a bakery, also a Lutheran mission, a church, and a school. It is on an island, surrounded by several others, which are visited by the natives for seals and eider-duck. The whole southern part of Greenland is a region of wild mountains, rising in peaks to nearly 8000 feet. Close to Namortalik is the Taser- miut fjord, some 50 miles long, with a most luxuriant vegetation in summer, and with heat and mosquitos enough to make one The observations of Axel Ham- 66° N. lat. and Cape Farewell, flows upon warm water.

The quantity of ice on the east coast diminishes in spring and summer, and, according to numerous observations made by Danish settlers and navigators on the south coast of Greenland, the polar drift-ice appears there in May, June and July, whereas in November, December, January and February there is no ice. Mr. Hamberg believes, therefore, that the polar current is at its maximum in spring, diminishes in force during summer, and is insignificant in autumn and winter.

Soc., Sept., 1884) gives an account of Karateghin and Darwaz, regions situated on the upper course of the Oxus. Karateghin occupies the middle course of the Kizyl-see or Surk- hab, the largest tributary of the Oxus; while Darwaz, to the south of Karateghin, lies upon the Panj or main Upper Oxus and upon the Hing-ab, a tributary of the Surkhab. These two Bokharian provinces are walled in by snow-capped mountains ten to eighteen thousand feet high, and can only be entered by ways passing over the most difficult passes. Karateghin consists of a series of hollows or expansions in the valley of the Surkhab, and each of these expansions gives evidence, from its terraced clayey sides, that it was once a lake. The smaller basins are separated by mountain spurs. Grain and fruits of the temperate climes grow in abundance in this elevated valley. The Tadjiks of Kara- teghin claim to be descended from the soldiers of Alexander’s army, and Mr. Michell believes that the hereditary chiefs may really be so descended, but suggests that the Tadjiks themselves may be the descendants of the ancient Bactrians. The principal valley of Darwaz is the grassy and fruitful vale of the Hing-ab, whither, spite of the asperity of the roads, immense herds of cattle are driven every year from Hissar to graze. Another well-to-do valley is that of the Saghri-Dasht, a tributary of the Hing-ab. The valley of the Panj itself has little cultivable land, but in it stands Kila-Khumb, the residence of the Bek of Darwaz. At the south-east limit of Darwaz is an impassable gorge, separat- ing it from Roshan, which belongs to Afghanistan. Sir Hy. Rawlinson stated that Roshan was the exact Oriental rendering of Roxana, and it was here that the Bactrian chief, Oxyartes, the father of Roxana, had his residence. The Tadjik has straight, fine black hair, and deep-set, lively black eyes, and is thus quite different from the Uzbeg Tartars. MıscELLANEOUS Nores.—Mr. C. Winnecke has explored a part of central North Australia near the western boundary of Queens- land, as far as 136° 46” E. long.

RODENTIA OF THE EUROPEAN TERTIARIES.'—In this important monograph of 161 pages M. Schlosser has given us a much needed account of a series of Mammalia which has been hitherto much neglected. Comparatively little information as to the char- acter of many of the European genera has been accessible hith- erto, and we therefore welcome this work as filling an important hiatus in our literature. The greater number of the extinct species of Europe belong to the Hystricomorpha and the Sciur- omorpha; and in the former suborder the important family of the Theridomyidz is especially characteristic of that continent. To it M. Schlosser refers the genera Theridomys Blv. Protechimys g. n., Archeomys L. and P., and Trechomys Lart., which M. Schlosser remodels. The total number of species belonging to this family recognized, is fifteen. An important new genus is added to the Hystricomorpha, Nesokerodon Schloss., with two species from the French Phosphorites. Considerable attention is given in the monograph to the rooting of the molar teeth. The book is well illustrated with eight 4to plates. A few blemishes appear in the text, such as the printing of the synonyms separately and in the same type as the correct names of the species. Also there is a good deal of confusion in the names and ‘authorities which are quoted from the American literature of the subject. MARSH ON AMERICAN JuRAssic DINOSAURIA? Part vur.—In introducing the description of the principal characters of the skele- ton of the carnivorous Dinosauria Professor Marsh remarks that, “Although much has been written about these reptiles since Buckland described Megalosaurus in 1824, but little has really important parts of the skeleton in good preservation, has afforded the writer an opportunity to investigate the group.” The best preserved remains belong to species of Allosaurus and Cerato- saurus. The latter genus proves to be one of the most curious of the Dinosauria. Marsh finds that the bones of the pelvis are coossified as in birds; and ina subsequent article (2. c\ that the metatarsals are coossified also, giving a metapodium a good d like that of a penguin. These facts quite close the argument in favor of the descent of the birds from the Dinosauria, although . ropaischen Tertiars nebst Betrachtungen ü. d. diami oe h, Eatvickelung 55 Nager überhaupt; von M.

Sot Sct. rts, 1884, Pt. 1, 329; Pt. I1, p. 161. | 68 _ General Notes. [January, in some of the pelvic characters we must, according to Baur, look to the herbivorous forms for the closest resemblance. The cervical vertebra of Ceratosaurus havea very peculiar articulation, being deeply concave posteriorly and plane in front, thus prevent- ing the reception of the anterior face deeply into the posterior face of the centrum in front. The depth of its shallow entrance is marked by a ledge on the sides of the anterior face. The skull of Ceratosaurus is peculiar, according to Marsh, in the large anteorbital opening. Professor Marsh separates Ceratosaurus as type of a family distinct from the Megalosauride, but it does not appear from his diagnosis of the latter on what grounds. The only distinctive character given to the former is “ horn on skull,” which is cer- tainly of not more than generic value, and may not even be that. The skeleton of the Megalosauridz is little known, but it is probable that the Ceratosauridz must be distinguished from them by the coossified metatarsals and pelvic bones. The other dis- tinct family appears from Marsh’s definitions to be the’ Zanclo- dontidz, where the cervical vertebra are biconcave, and the pubes different. I have elsewhere? referred to Professor Marsh’s tend- ency to exaggerate the systematic value of various characters,’ and reiterate the opinion that his “orders” are of no higher rank than suborders, As usual, Professor Marsh omits the customary reference to facts already determined by others. Thus he states that some of these reptiles probably rested on the free extremities of the pelvis in a sitting posture (p. 336). The writer pointed out this peculiarity as long ago’as 1870. Professor Marsh also finds (p. 337) that the presence of various genera of Dinosaurs, closely allied to these American forms, in essentially one horizon in the Isle of Wight, suggests that the beds in which they occur are not Wealden as generally supposed, but Jurassic. The American beds were at first referred to the Wealden by Marsh, and subse- quently to the Jurassic by the writer in “ Relations of the Hori- zons of Extinct Vertebrata of Europe and North America.” 4 This paper is well illustrated by six plates.—E.

The area of Tertiaries in this State must now be extended over a wide stretch of country, from the tops of Laurentian hills, near Raleigh, and the higher elevations of the Huronian slates, to from fifty to seventy-five miles south-eastward, along the course of the Deep river, and so onward to the South Carolina border, reaching at one point an elevation of 600 feet above tide. This leaves the quater- nary, like the Miocene, to be represented by a thin and broken covering of superficial deposits, of only a few feet to a few yards in thickness, and reaching from the coast only about 100 miles inland and an elevation but little above 100 feet.— W. C. Kerr, Raleigh, N. C. CHARACTER OF THE DEEP-SEA DEPOSITS OFF THE EASTERN Coast oF THE UNITED States.—At the Newport meeting of the National Academy of Sciences, Professor A. E. Verrill gave the results of explorations made last summer by the U. S. Fish Com- mission steamer Albatross, sixty-nine dredgings having been made during four trips between Wood’s Holl and a point off the Virginian coast. Of these dredgings, 5 were in depths between 2000 and 2600 fathoms (4 successful); 20 were between 1000 an 2000 fathoms ; 24 between 500 and 1000 fathoms ; 8 between 300 and 500 fathoms; 12 between 75 and 300 fathoms. Another trip has since been made to explore more extensively the zone tween 40 and 100 fathoms. ; Some very interesting and important discoveries were made in regard to the nature of the materials composing the sea-bottom under the Gulf stream at great depths. These observations are _of great interest from a geological point of view, and some of them are contrary to the experience of other expeditions, and not in accordance with the generally accepted theories of the nature . of the deposits far from land. The bottom between 600 an = Fast 70 | General Notes. [January, large angular masses, sometimes weighing more than fifty pounds, have been brought up in the trawl, and have not been washed away appreciably, notwithstanding the rapidity with which they have been drawn up through about two miles of water. In fact these masses of hard clay resemble large angular blocks of stone, but when cut with a knife they have a consistency somewhat like hard castile soap, and in sections are mottled with lighter and darker tints of dull green, olive, and bluish gray. When dried they develop cracks, and break up into angular fragments. This material is genuine clay, mixed with more or less sand, showing i under the microscope grains of quartz and feldspar, with some scales of mica. More or less of the shells of globigerina and other l foraminifera are contained in the clay, but they make up a very small percentage of the material. In all our ten localities, between 2000 and 3000 fathoms, the bot- tom has been “ globigerina ooze.” We have never met with the “red clay” which ought .to occur at such depths, according to the observations made on the cruise of the Challenger. The temperatures observed with the improved thermometers now used on the Albatross were between 36.4° and 37.0° F. in 2000 to 2600 fathoms. But temperatures essentially the same as these were also taken in 1000 to 1500 fathoms, and even in 965 3 fathoms one observation gave 36.8° F. It follows from these ob- servations that nearly the minimum temperature is reached at about 1000 fathoms in this region. GEOLOGICAL News.—General—The water of the Atlantic, In- dian ocean, Red sea, and eastern part of the Mediterranean, has been shown by M. Dieulafait to contain manganese. The man- ganese can scarcely be perceived in sediments consisting of sus- pended matter, but is very perceptible when the water is free from suspended particles. In this way the well-known concre- tions of manganese in the deep seas were accounted for. He con- cludes that one of the conditions for the formation of chalk is the absence of foreign substances, and thus it may be expected that chalk should generally be rich in manganese. It was found that the quantity of manganese in fifty-six specimens of chalk ` from the Paris basin was fifty times more than in specimens of granular colored limestone. Archean—M. Barrois calls attention, in his notes on metamor- phic rocks of Morbihan, to the way in which the schists gradu- ally lose their crystalline character as they recede from the gran- ite, until at length they pass into slate; while the metamorphic sandstones also change as they approach the granite, so as to show four distinct stages. Devonian.—M. Paul Vernskoff has published an important memoir upon the Devonian deposits of Russia, comprising : (1) their geographical distribution in the centre and north-west of that 1885.] Geology and Paleontology. 7i country ; (2) a historical account of investigations of these de- posits; (3) a description of their structure, and (4) a comparison of the Devonian of Russia with that of western Europe. The author concludes that the lower stages of the Devonian are lack- ing in Russia, which has only the middle and upper stages. Carboniferous —M. Fuchs has brought together abundant de- tails respecting the geology of Cochin China and Tonkin. The carboniferous limestone is particularly well-developed, is of crys- talline structure, and generally gray or blackish in tint. These rocks are violently dislocated in Tonkin and at Tourane, and form crenellated inaccessible cliffs of most picturesque shape. The islets and reefs which border the northern coast of the Gulf of Tonkin, and which have for centuries been the refuge of pirates, are forined of this rock. Upon these limestones rest beds of clay-sandstones with layers of coal at their base. These beds spread over large areas, and are certainly more than a thousand meters in thickness. Some twenty species of plants, some new, others like European coal measures, have been described. M. Fuchs then describes the coal basin of Tonkin, which forms a belt about 111 kilometers long, parallel with the coast. Only the southern border of this has been explored. The best known coal regions of Tonkin are those of Hon-Gac and of Ke-Bac. Analysis has proved that the coals of Tonkin are combustibles of good quality, adapted to diverse industrial uses———W. Dames in remarks upon the supposed “Phyllopod” nature of Spath- iocaris, Aptychopsis and similar bodies, maintains that some of these are undoubtedly goniatites, and that others cannot at present be interpreted, but that among these last none are phyllopodous. Permian.—M. A. Gaudry announces that the study of Euchir- osaurus has been facilitated by that of portions of Archegosaurus = which have recently been found. Euchirosaurus possessed an a dominal cuirass, and was capable of powerful lateral motion, so that it was truly a reptile, progressing in reptilian fashion. e scales of the cuirass were very hard, and the vertebre had neural spines which not only had lateral processes like those of several American species, but was also furnished with articular facets so as to be slightly movable upon the centrum. Jurassic-—M. De Loriol continues, in the Pal@ontologie Fran- caise, the publication of his monograph of the Jurassic crinoids of France. Sixty-four species of Millericrinus alone have been described from the Jurassic beds, and twenty-six of these are new. All but feur of the known species of this genus have now been found in France. No modern species recalls in the least this form of crinoid, with its pyriform or even globular calyx mounted on a long stem fixed by numerous tendrils. M.

In the specimen of Archæopteryx in the Berlin Museum, those parts are preserved which are wanting in the example in the British Museum, and the pelvis, hind-limbs, and more perfect tail supply valuable de- tails.

Cretaceous —The variability of ancient species is well demon- strated by five abnormal specimens of Hemiaster from the creta- ceous of Constantine, Algeria. In some of these one of the ambu- lacral areas is entirely or partially atrophied, while in others there is a doubling of one of the ambulacra. These animals, provided with four or six ambulacra, attained as full a growth as normal examples. Tertiary.—The series of tertiary deposits which lie along the Alsatian slope of the Vosges, and which are often rich in bitu- men, have by M. Blecher been determined to belong to the Ton- grian stage. The deposits are sometimes marly and of deep-sea origin, at others sandy and littoral, according to the widening or narrowing of the zone between the Vosges and the Black forest. The vegetable fossils are numerous and remarkable. Pomel considers the terrestrial deposits of the Sahara as forming two categories. The more ancient he places in the pliocene, and names Saharian. The author endeavors to show that, during the pliocene and quaternary, the maximum zone of precipitation was displaced northwards, and successively passed from the central Sahara to the Atlas, then to central, and lastly to northern Europe.

The lower stamens appear at either side of this groove at the corolla’s throat (Fig. 1), the upper stamens are shorter and en- tirely included. The style is slightly shorter than the lower stamens and lies between them (Figs. 2 and 4) in such a way that if the bees fail to visit it, it can be self-fertilized, ¢. e., if the pollen of its own flower is not impotent. The stamens are erect in the bud and the style is but slightly curved forwards. In the older m Fig. I. Fig. 2. Fig. 3. Fig. 4. Fic. 1.—Flower from front view. Fic. 2.—Section of flower.

The stigma (Fig. 3) is not exactly lobed, but the harder tissues at its tip are lobed, and a softer layer of tissue lies between, exuding a sticky substance. The flower is therefore but poorly specialized for cross-fertiliza- tion, the hairs constituting its only special characters. I have noticed most of the visits by bees in the evening. In the middle of the day they seem to prefer other plants—Azg. F. Foerste, Granville, Ohio. Botany IN Kansas.—In the first number of the Bulletin of the Washburn Laboratory of Natural History Professor F. W. Cragin publishes lists of Kansas mosses, lichens, alge and fungi. Of the mosses a dozen are given, determined by Eugene Rau. lichens were identified by H. Willey, and number sixteen species ` and varieties. A dozen algæ are given, identified by Francis Wolle. The list of fungi includes only the Hymenomycetes, of which 158 species are enumerated. In this latter list are some / new species, viz., Agaricus alveolatus Cragin, with a pitted pileus ; Trametes kansensis Cragin, and Dedalia tortuosa Cragin. This _ bulletin gives promise of good work, and no doubt will do much to stimulate the collection and identification of the lower plants of the State. ; FERTILITY oF Hysrips.—From a long article recently published by Thos. Meehan, we condense as follows, regretting that space will not permit its reproduction entire.—{ Ææ. ] ae The facts are that the recorded and undisputed cases of sterility in hybrids among plants are so rare that it would seem the onus should be on that side to prove the point. The writer does not know where to look for cases of undoubted hybrids among 74 General Notes. [January, ; plants that are sterile. In most cases where reference is made it . has been assumed that they were hybrids, because there was some difference in appearance from the normal form, or perhaps from the simple fact of sterility alone. The curious Pyrus polvil- Jeriana in the garden of the museum at Paris is a case in point. This was known in Bauhin’s time, and when the knowledge of hybridism was developed, believed to be a cross between an apple and a pear. It bore fruit, but it was thought there was no seed in them. But in 1860 Decaisne cut large numbers open and found thirteen seeds in 150 fruits. In 1864 sixty-two seeds were found in 139. Now the very fact of the fertility varying with different seasons shows that sterility was in relation to the struc- ture in connection with external circumstances, rather than to any physiological imperfection in the reproductive organs them- selves. In some other locations, where the circumstances should be uniformly as they were in 1864, we should have a tolerably fertile tree. Seedlings from the tree showed a relationship to Crategus aria,and, indeed, from what we know of departures from normal types without any pretensions to hybridism, one may _say that there is no fair reason for regarding this curious tree as a hybrid, or the sterility as having anything to do with the ques- tion of hybridization. The writer has a tree certainly raised from Malesia tetraptera, certainly no hybrid, as there is nothing near for the parent tree to hybridize with, which is so different from the parent type that it can scarcely be called a Halesia. It is as sterile as the most famous hybrid could be. In short, sterility is well known to often follow the union of two individuals in the animal kingdom, and there are innumerable cases of sterility among individual plants. Sterility will often be characteristic of a whole race, and often of a whole species; and we may say positively that there is no more sterility among recognized hybrids than we find of every-day occurrence where hybridization is certainly out of the question. But let us give the illustrations of fertility in hybrids : * %* * Flowering plants furnish the best evidence because we know the whole history, The writer of this raised the first hybrid fuchsia. Fuchsia fulgens was the male parent and F.. longiflora the female, the latter being itself a garden form. These two belonging to different sections of the genus, are not only good species, but have been regarded as of distinct genera. The progeny of these hybrids were fertile. Other hybridists used equally distinct species for the male parents, such as F. corymbi- fora and F. serratifolia. Alithe numberless garden varieties now in existence have been raised from these original hybrids. Many successive generations have been raised. There are some sterile individuals occasionally, but not more than is found with individ- uals with normal species. The writer also obtained hybrids be- ERETTA ~ 38854 Botany. 75 tween Gesneraceous plants of two genera, Gloxinia rubra and Sin- ningia guttata. These were fertile. Indeed, European florists have united many supposed genera in this order. Conservatories teem with them. The writer never saw a sterile one. lis is also true of Begonia. Large numbers of those in our conserva- tories are hybrids, all fertile. * * * * All our garden Gla- dioli are fertile. The original of these forms is a hybrid between Gladiolus cardinalis and G. floribundus. Our garden geraniums and pelargoniums are from many very distinct species, so distinct in appearance and general character that they might almost be regarded as distinct genera. Their ‘offspring are occasionally sterile, but with these very few exceptions are as fertile through many score of generations as the originals. * * * * The Cape heaths of our greenhouses—species of Erica—have remark- ably distinct forms among them, yet any of them hybridize freely and produce offspring as fertile as their parents. 2:8 ode dence for the fertility of hybrids) * * * The history of the grape in America is one of a long succession of fertile hybrids, though perhaps the distinctness of the species might be a ques- tion. There is such a regular gradation that no one can refer a form in every case to its proper species. Still, when we take the wild fox grape and compare it with the grape of European vine- yards, or a scuppernong and a fox grape, all will admit that in no sense can these be regarded as one species. Yet they all hybrid- ize, and the hybrids are fertile. Ati M. Naudin, a very energetic French experimenter with hybrid plants, gives as the results of his observations that never more than twenty-five per cent of hybrids were sterile, and of these numbers had fertile pollen ; but even this proportion may have had more to do with the climate or surroundings than with abso- lute sterility. In America, so far as the writer of this has had the opportunity to observe, there is no reason to believe there is any more sterility attached to hybrids than to ordinary plants.— The Independent. Tue YouncEer Scoot or Boranists—lIn a recent number of Nature Rev. Geo. Henslow spoke of the “evil effects of the younger school of botanists not recognizing the importance of first training students in a thorough course of practical and sys- tematic botany before proceeding to laboratory work.” To this W. T. Thistleton Dyer replies with some warmth: “I am afraid I am not wholly free from some responsibility for the proceedings of ‘the younger school of botanists,’ the effects of which he re- gards as evil. In the face of the successful revival in this country of many branches of botanical study which the younger school has effected, Iam emphatically of the opinion that these effects are the reverse of evil. I believe I was one of the first to organ- b ba 76 General Notes. [January, -ize a course of so-called laboratory work in botany on lines which it is only right to say were borrowed and extended from the teaching and example of Professor Huxley. In what I attempted I had the generous aid of many now distinguished members of the younger school. I do not doubt that they have immensely improved on the beginning that was in the first instance some- what tentatively made. But the principle, I believe, has always remained the same, namely, to give the students a thorough and practical insight into the organization and structure of the leading | types of the vegetable kingdom. When, therefore, Mr. Henslow, himself a teacher, asserts that such laboratory teaching as this should be preceded by a thorough course of practical and sys- tematic botany, it appears to me that he is bound to explain what he precisely means by this very dark saying. For if botanical laboratory work in this country is not thorough, is not practical, and in dealing with types drawn from every important group is not systematic, it is important to know in what respects it falls short of these requirements.” New Species oF NortH AMERICAN Funoi.—Septoria purpur- ascens—H ypophyllous on small reddish-purple spots without any definite border, and often confluent so as to give a purplish dis-- coloration to large areas of the leaf; perithecia prominent, scat- tered, collapsing above, 150-190 in diam.; spores fusiform, hy- aline, slightly curved, endochrome thrice divided, 30-50 X 3m On leaves of Potentilla norvegica, Adirondack mountains, N.

An account is given of the excursions of the club, and finally the whole is summed up in an editorial note upon the results of the Philadelphia meeting, in which, after pointing out the good results which the meeting accomplished, the editor properly criticises “the low average quality of the botanical papers presented before the association.” In spite of the fact that the attendance included “ some of the most distinguished names of the science in this country, the botanical communications in no instance exhibit that profound research or comprehensive statement of laws or relationships, or other characteristics that would entitle them to rank with the better papers presented by the zodlogists, physicists or chemists.” We most heartily en- dorse the remark that “ it lies with individual workers to see that this does not remain so.” ENTOMOLOGY. Cc: bas: ON THE FIRE-FLY oF ITALY —Luciola i is one of the . have wings and elites the male has only six ool eats against seven in the female; but the terminal segment of the b 78 General Notes. [January, male is large and bears indications of transverse division, as if it represented two somites. Dr. C. Emery, of Bologna, was induced to examine this species (Luciola italica L.) by the publication of Wielowiejski’s study of Lampyridez in Zeitschrift f. Wissen. Zoologie, 1882. His own work was cut short by want of material, as last season was un- favorable in Italy; and it is only the preliminary views which he now publishes (same journal May, 1884). Some of these results are valuable. He thinks that the female Luciola, though having wings, is unable to fly; though a friend alleged that he found both sexes flying iz copula, The females are always very scarce, have two luminous spots on the ventral part of the abdomen (5th abdomi- nal segment), whilst the males are common, and have the ventral parts of the 5th and 6th abdominal segments forming a large lumi- nous organ. He is of opinion that in the imago state they never eat, and he finds the fore intestine filled with large air-sacs. [It might be well to compare this with the rectal air-sacs of larvze of dragon-flies, and to see whether they may not be ex- tensions of the tracheal system into the intestine, thus serving as lungs, and correlated with the great oxygen-consumption in the luminous organ]. The abdomen contains the luminous organ in its ventral half, backed dorsally by a fat-body with concretions of uric acid. There are also fat masses in the prothorax, that of the male as well as its testes being rose-colored. The luminous organ is richly supplied with trachee, the larger tracheal trunks being /ined with bristles; and the fine tracheal stems or branches run down- wards through the luminous organ, perpendicularly towards the horizontal surface of the abdomen. On a ventral view with weak magnifying the luminous organ is found to consist of bright round or oval areas, one of the per- pendicular tracheal stems being in the center of each area, and between the bright areas are dark interspaces. The whole organ is constituted of vertical columns or cylinders, consisting of transparent tissue surrounding a tracheal stem and its branches, and the gaps between adjoining columns filled up by cellular “parenchymatous” matrix. n a side view we can see the large tracheal trunk sending down the vertical stems, and marked not by spirals, but by trans- verse ridges. [This is one of the many incidental proofs coming up that the tracheal system has been misunderstood, that it is really the result of crenulations, and that there are no distinct spiral threads. Emery says: “I speak purposely of transverse ‘ridges of chitin, and not, as is usually done, of a chitinous spiral, for such does not in fact exist here.” By teasing the substance of the luminous plates we are able 1 The remarks in brackets are by the reviewer. 2 ne as 1885. | Entomology. 79 to follow the tracheal branchings. Each stem forming the axis of a column, divides racemosely into branches, and each branch bifurcates into a pair of capillaries whose walls are perfectly smooth. On the application of osmic acid to the abdomen of the living insect, death does not follow immediately, but the luminosity is continued for atime steadily. Long before the animal has ceased to move, the luminous plates begin to grow brown, the change proceeding from the anterior part, from the place where the trachee enter. The brown color becomes concentrated in round fields corresponding to the vertical columns, each surrounded by a circle of light. The terminations of the vertical tracheal stems are enclosed in cylindrical lobular masses, the columns of the luminous organ, the trachee sending out its racemose branches within each column; in macerated specimens (by osmic acid and thymol) dark masses are seen where the branches bifurcate to form the capillaries; the cells of which the columns consist exhibit no nuclei. [Judging from these figures it would seem as if the dark spots represented the nuclei: if this be the case every tracheal branch is in a cell and its place of bifurcation at the cell-nucleus.] Emery finds no case of the anastomosing of the tracheal capil- laries either of the same or of different stems; he is satisfied that no such anastomosing occurs in Luciola. His view is opposed to that of Kölliker and of Wielowiejski on Lampyris. [The con- clusion of Wielowiejski appears to be without sufficient founda- tion; his figures show only a casual collection of a few of the intricately twining tubules. The cylindrical lobes or columns of the luminous organ are separated from each other by a granulated substance, and the tracheal capillaries extend to this and to the granulated paren- chyme-cells, penetrating between the cells but not entering them. The dorsal fat-layer was examined for the purpose of establish- ing homologies. It is white, has urate concretions swimming in the plasma of its cells, which are {not distinctly limited by cell walls; but it has nuclei like those of the parenchyme of the luminous organ; and these facts as well as the tracheal arrange- ments favor the view that the luminous parenchyme is derived from the fat-body. It cannot be that the latter with its urate concretions is the result of combustion in the luminous organ, for the tracheal arrangements negative such a view. In comparing Lampyris, Emery concludes that M. Schultze’s tracheal end-cells are represented in Luciola by the bright cell- elements of the luminous cylinders enclosing the tracheal stems ;. that the tracheal branching is similar; also that the reactions are the same, csmium being precipitated so as to darken the sub- stance in both cases. In Luciola there is a higher differentiation of parts. : - 80 General Notes. [January, Transversely striped trachez never enter the fat-masses of Lu- ciola; it is only the smooth tracheal capillaries that pierce them, somewhat coarser than’those of the luminous organ, and retain- ing air in their lumen. The fine branches heré arise not ina racemose manner, but by a fascicle of two or more capillaries arising at a point, and running in complicated windings before they enter the fat masses. They were never seen to anasto- mose; the layer of matrix was very thin on the striped trachee, ' but much thicker on the capillaries. Sometimes the ends of the capillaries lying on a cell of the matrix were free; between two capillaries the matrix often formed a thin web, and rarely the matrix was gathered into a globule terminating the capillary. Real tracheal end-cells were not seen. As to the physiology of the luminous organ, the seat of the luminosity is at the boundary between the tracheal cylinder and the parenchyme-matrix around it: this is the place where ` the capillaries begin and where the osmic acid is reduced by the illumination, where oxygen is consumed. [Here we have an ad- ditional argument for the doctrine that the oxygenation of the tissues depends not on a circulatory fluid around the trachee, but on the activity of the tracheal terminations.} The action of osmic acid at this part is an experimentum crucis, proving that at the bifurcation the plasma of the parenchyme coming to meet the fine tracheal capillaries, receives oxygen from them, and hence combustion arises where the chitin of the capillaries is very thin. — Emery holds that the use of the. light-producing power is not merely for attracting the rare females, but for frightening such nocturnal enemies as bats. Luciola on being crushed emits an unpleasant flavor, but its taste is not at all bitter—G. Macloskie. ENTOMOLOGICAL Notes.—A case of mimicry is noticed by C. _ M. Weed in the same number ; Tetracis lorata, a white geometrid moth was found adhering to the stamens of a flower of the may- apple, its head toward the center, the wings being easily mistaken for the petals; a second one was found in exactly the same posi- tion. .

At a recent meeting (July 2) of the London Entomological Society, Mr: C. O. Waterhouse exhibited various species of phytophagous beetles to show the extraordinary effect that exposure to light had pro- duced on their colors.

Milne-Edwards, of the last expedition of the Talisman, has been published and translated by the /ndependent. The expedition of 1883 was divided into several distinct steps, the aim being to examine: 1. The coast of Africa as far as Sene- gal, then the shores of the islands of Cape Verde, of the Cana- ries and Azores, and, finally, to examine the Sargasso sea and study its surface fauna as well as the nature of its depths. In one of the first trials on the coast of Spain, the Talisman party found an accumulation of dead shells, having the aspect of the pliocene fossils of Sicily, and among which M. Fischer rec- ognized Cypridina islandica and Mya truncata, which are common in boreal seas and do not live south of England. They were as- sociated with some Mediterranean or pliocene shells. Off the coast of Morocco and the Sahara were found, at the depth of 500 o 600 meters, numerous fishes (Macrurus, Melanocephalus, Hop- lostethus and Pleuronectes), crustaceans such as certain unde- scribed shrimps with an enormous rostrum, pointed like a sword, which was named Pandales ; other shrimps of the genera Penzus, Pasiphaea, some small crabs (Etalia, Portunus and Oxyrhynchus), some red Holothurians, examples of the soft-shelled sea-urchin (Calveria), which formerly lived in the chalk formation ; also many large-sized sponges, some in the shape of an enormous chapeau (Askonema), the others lamellated (Farrea), the others more or less globular. : Deeper down, toward 1000 and 1500 meters, fishes abounded ; e : VOL. XIX.—NO. 1. ' 82 General Notes. [ January, there were still Macruri, to which may be added species of Ba- thynectes, Coryphenoides, Malaccocephalus, Bathygadus, Argy- ropelecus, Chauliodus, Bathypterois, with fins transformed into tactile appendages (B. /ongifilts), Stomias, Malacosteus, with the skin of an intense black, and with phosphorescent jugal plates ; Alepocephalus, etc. All these fishes, on arriving at the surface, were dead, the gas was separated from the blood, so as to produce a sort of froth, and many of them were deformed by the enor- mous distention of their swimming bladder. The species of this group, which inhabit the abysses of the sea, have a special aspect, and are readily recognizable. Their skin, covered with a very thick coat, never has lively colors; it is grayish, or of a velvet black, and the scales are not very solidly attached; the muscles are not thick, and are of a soft consistence ; their bones are soft and have a spongy structure; their mouth is usually large, and armed with sharp, hook-like teeth. Most of these fishes live in the ooze, or at its surface. All that were observed by the Talis- man party had normally developed eyes, whose mode of action in a medium completely obscure would be difficult to understand, if it did not find its explanation in the existence of phosphores- cent plates, or of a covering of luminous slime, which can shine at a certain distance. In the black Malacosteus these plates are situated at the eyes; in other species they are disposed in lines on the lateral parts of the body. The Pandali have given place to the Heterocarpus, with the carapace furnished with projecting edges; to species of Penzeus, whose posterior feet resemble antennz, and to enormous shrimps of a blood-red color, and with extremely long antennz, which were previously unknown, and should be placed in the genus rista. These crustacea were common, and several times they were caught in such abundance that the cook claimed his share of them. The Nephropsis appeared at this level; they are blind crustacea, which externally resemble some kinds of crayfishes, ot a coral red. Their geographical distribution seems to be very extensive ; for they have been found on each side of the Atlantic, in the Antilles, while a Chinese species which seems to be identi- cal, at least very near, has been dredged at a great depth near the Andaman islands. The Pentacheles and the Polycheles, whose eyes are atrophied, conceal themselves in the ooze, only extending their long, slender pincers adapted to seize their prey. They alone represent in actual nature the Eryons, so common in the jurassic seas. The Nematocarcini, with remarkably long feet, live in the same conditions. The crabs have become rarer, though some species still exist. These are the Maians (Scyramathia, Lispognathus), some Homolians of a new species, Lithodes of great size, hereto- fore peculiar to Arctic and Antarctic seas. A yery large Lithodes | A 1885.] Zoology. 83 was dredged by the Talisman, under the tropics, at the depth of goo and 1000 meters. This species, distinct from all others yet known, has been named Lithodes tropicalis. There also occurred several crustacea of the group Galathez, whose eyes are trans- formed into spines. The sponges are extremely common at the surface of the bed of this part of the ocean. Most of them, as well known, have a silicious skeleton. everal species of the beautiful Rosella and of Holtenia were found living in profusion. Their long hairs of white silex are buried in the mud, and the sponges, with a form like a rounded vase and a narrow orifice, project above the mud. They were especially numerous between 900 and 1 200 meters, and at certain points they seem to form veritable beds. The Aphrocallistes, whose solid framework, composed of regular cells, affects the most elegant forms, and gives the appearance of a honeycomb, form extensive banks ; they were found ordinarily associated with and attached to, branching corals of the genera Lophohelia and Amphihelia. The soft sea-urchins, such as the Calveria, become more num- erous, and at 1000 meters they probably live crowded together like the Echini of our shores. Some Holothurians, of the genus polyps, we find in these new conditions a different population. Off Cape Ghir and Cape Noun,"under the 30th parallel, at 120 miles from the shore, the Talisman explored, for several days, a very regular bank, whose depths only varied between the narrow limits of 2075 to 2300 meters. It was on this same bank that, on the 2d of August, 1882, the Travailleur brought up in its nets the singular fish described by M. Vaillant under the name of ` Eurypharynx pelecanoides, associated with a great number of new or rare species. This year two specimens of Eurypharynx have been captured, one at 1050 meters and the other at 1400 meters, on the bottom of the reddish ooze west of Morocco. Similar banks, but less rich, had been already explored by the Zaisman on the Morocco coast, off Rabat, between Cape Blanc, northerly, and Cape Cantin, a little before the arrival of the Talisman at Mogador. These were found again under the 24th parallel ; also off the Arguin bank. At this depth, the fishes were represented by some very rare species, such as the Melanocetus johnsoni, which had been as yet known only by a single example found floating on the water by fishermen near Madeira. With its enor- mous mouth it could swallow a fish considerably larger than its own body, and its prey would lodge in a sac which hangs below its abdomen, The first ray of the dorsal fin is developed into a true 84 General Notes. [January, tactile appendage, recalling that ot the anglers, and serving the same purpose. Some Bathytroctes, a Stomias with phosphor- escent plates, several Malacostei and some Halosaurus live also on the same oozy bottom. Many Crustacea, new to science, were here dredged, and belonging principally to the group of Galathee of the genera Galathodes, Galacantha, and Elasmonotus, whose eyes, deprived of any cornea, are covered with an orange colored pigment, and should be useless for vision. With them were dredged several new kinds of mollusks, among them a Dentalium of large size (D. parfait’) and a Pholadomiya. Between Senegal and the Cape Verde islands, the bottom, at a depth of from 3210 to 3655 meters, consisted of a greenish mud rich in life. Some of the animals found there did not differ from } those found on the bank situated at the depth of 2300 meters. Others presented peculiar characteristics. These were fishes of the genus Bathynectes, Synaphobranchus, and Myrus, some Aristes, with bright colors and very like those at depths of from 1000 to 1200 meters, but with smaller eyes. Among Crustacea were Pasiphaés, hermit crabs and Myside. Among mollusks were a new species of Bulla, and another gasteropod belonging to an unknown genus (Oscorys sulcata Fischer); among Echino- derms were species of Ctenodiscus, Ophiurans, and species of Ophiomusium. Between St. Antoine and St. Vincent the fauna surpassed in richness any regions previously explored. July 29th, at a depth of from 450 to 600 meters, the dredge came up at the end of an hour charged with more than a thousand specimens of fishes be- longing mostly to the genus Malacocephalus; with more than 1000 Pandali, 500 amphipods, with long feet, a new species of Nematocarcinus, 150 Pasiphaés spotted with red, large carmine- red Aristes, and many other forms—7To be continued. THE DEPTH TO WHICH SUNLIGHT PENETRATES WATER.—The much-di d questi tothe depth to which sunlight penetrates water, and the influence which such penetration, or want of pene- tration, may exert upon the phenomena of life at great depths has attracted renewed attention of late on the part of both phys- icists and biologists. The carefully conducted observations of Professor F. A. Forel, of Geneva, made upon the Lake of Geneva in 1874, proved—at least as far as the resources of photography and the human retina permitted—that the limit of absolute dark- ness in that lake was reached in summer at the very moderate depth of 45 meters, and in winter at 100 meters. Under normal conditions of sight a shining object disappeared when immersed below 16 to 17 meters. Asper, who continued the researches of Forel upon the Lake of Zurich, found in 1881 that photographic plates sensitized with bromide of silver emulsion indicated .the penetration of light to at least 90 meters. But while the re- searches here recorded fix the limit of luminous perception as O a Serer sre 1885. ] Zoology. 85 dependent upon the powers of the human retina, they do not necessarily determine the same for the retina and visual nerves of the lower animals, Indeed, the presence of well-developed eyes in many of the animal forms inhabiting the greatest depths, no less than the varied coloring of their teguments, have frequently been taken in evidence to prove not only the existence of light there, but also the unequal visual powers of the different organ- isms. Professor Verrill has recently enunciated the startling prop- osition that not improbably light of the intensity of ordinary moonlight may penetrate to depths of 2000, or even 3000 fathoms, and that possibly some sunlight penetrates even to the lowest bottom of the ocean. Evidently, however, the tegumen- tary coloring as we observe it has no bearing on the question at issue, inasmuch as it appears as such only when brought within the influence of white light, which may be at, or quite near to, the surface of the water. Whether or not the quantity of phos- phorescent light emitted by the organisms themselves is sufficient to account for the full development of visual organs, still remains to be proved. In the meantime, the recently conducted investi- gations of a special committee of Swiss scientists, among whose names we find those of Sarasin, Soret, Pictet, C. De Candolle, and Fol, seem to affirm in a general way the conclusions reached by Forel—namely, that luminous penetration extends to only mod- erate depths. Three candles (contained in a lantern), immersed in the clearest water of the Lake of Geneva, were visible at a depth of 30 meters; and an electric light, at 3 meters further. The distance of clear vision was found to be but very feebly de- pendent upon either the increase of brilliancy in the luminous body, or its absolute magnitude. The extreme limit of the sun’s luminous action was determined photographically to be 250 meters, beyond which absolute darkness was supposed to prevail. —The Nation. ON THE STRUCTURE OF THE BRAIN OF ASELLUS AND THE EYE- LESS FORM CecipoT#A.—The results presented grew out of an attempt to compare the nervous system, particularly the brain and other cephalic ganglia, of the eyeless species of cave-inhabi- ting Crustacea and insects with the allied eyed forms. After de- 1 Read at the Newport Meeting of the National Academy of Sciences, Oct. 4, 1884. 86 General Notes. [ January, After describing the hitherto unknown peculiarities of the brain of Asellus and isopod Crustacea in general, the histological ele- ments, and the optic lobes, nerves, and eyes, the brain of the eye- less forms was then described. Cecidotzea in its external form is a somewhat dwarfed Asellus, with the body, however, much longer and slenderer than in the eyed forms, and with slenderer appendages. It is not usually totally eyeless, since in some in- dividuals a rudimentary eye, in the shape of a minute black speck, is seen on each side of the head; the spot varying in size in different individuals. From the examination of numerous microscopic sections it appears that the eyeless Cecidoteza differs from the eyed form (Asellus) in the complete loss of the optic ganglia, the optic nerves, besides the almost and sometimes nearly total loss of the pigment cells and lenses. As regards the other parts of the brain, no differences were observed; the proportions of the brain and the histological structure had remained unchanged in the eyeless forms. Besides the atrophy of the optic ganglia and nerves, the pigment mass forming the retina and also the lenses exist in a very rudimentary condition. In one specimen the number of lenses was reduced to two, and the lenses themselves many times smaller than in the eye of the normal Asellus. The steps taken in the degeneration or degradation of the eyes, the result of living in perpetual darkness, seem to be these: 1. The total and nearly or quite simultaneous loss by disuse of the optic ganglia and nerves, 2. Breaking down of the retinal cells. 3. The last step being, as seen in the totally eyeless forms, the disappearance of the lens and retina. That these modifications in the eye of the Cecidotza are the result of disuse and the loss of the power of vision from the ab- sence of light seems well established; and this, with the many | parallel facts in the structure of other cave Crustacea, as well as insects, arachnids, and worms, seemed to the author to be due to the action of two factors : (a) change in the environment and (6) heredity. Thus one is led by a study of these instances, in a sphere where there is little if any occasion for the exercise of a struggle for existence between the organisms, to a modified form of Lamarckianism in order to account for the origination of these forms, rather than the theory of natural selection, or pure Darwinism, as such.— A, S, Packard. On THE MORPHOLOGY OF THE Tarsus IN THE MAMMALS.— While occupied with an extended paper on the limb-skeleton of the vertebrates, I have obtained some new views on the homology of the tarsal elements in the Mammalia. For some time I have been puzzled by a bone in the tarsus of different mammals, which has always been considered a “ sesamoid.” Flower (Osteol. of Mamm., 2d edit., p. 317) says of this bone: 1885.] Zoology. 87 “ There is a large sesamoid bone on the tibial side of the tarsus, articulating with the astragalus, navicular and internal cune- iform.” Gegenbaur, who has done so much for the morphology of the limbs of vertebrates, says in regard to this: “ EineVermehrung der Tarsuselemente ist bei Nagethieren vor- handen, von Cuvier wie von Meckel ausführlich beschrieben. Es wird dieseVermehrung aus einer Theilung des Naviculare abgelei- tet und aus dem Hinzutreten eines tiberzahligen Knochens, der am inneren Fussrande des Cuneiforme! angelagert ist. Der aus der Theilung des Naviculare entstehende zweite Knochen liegt gleich- falls am inneren Tarsus rande, hinter dem vorhin erwzhnten, ist Strecke mit dem Cuneiforme ; zusammen. Wenn auch seine Lagerung am Astragalus und seine Verbindung mit dem eigent- lichen Naviculare die Ansicht von seiner Entstehung, wie sie die oben genannten Autoren äussern, als sehr wahrscheinlich erschei- nen lassen, so halte ich sie doch noch nicht fiir fest begründet. Das Vorkommen des zweiten Knochens, sowie ähnlicher über- zahliger Stücke am Tarsus der Monotremen schliesst die Mög- lichkeit nicht aus, dass auch das aus einer Theilung des Navic- ulare entstanden sein sollende Stück ein Accessorium ist. Daran wird wenigstens so lange festgehalten werden dürfen, bis der Nachweis einer Theilung der Naviculare aus der Entwicklung geliefert ist.” I do not consider this bone a sesamoid for the following reasons : 1. Its situation. It articulates by distinct and well-developed faces with the first cuneiform (Tars. 1), at the proximal prolonga- tion of which itis situated, and with the navicular and astragalus. In many rodents it articulates with the entire surface of the first cuneiform, 2. Its origin. In Cavia it is always found equally developed with the other tarsal bones and quite distinct. 3. Its relationship in certain phylogenetic old rodents, Cerco- labes and Erethizon. In these forms there is always developed a claw-like piece of bone, articulating with the “sesamoid” in question, and hence it loses all the characters of a “ sesamoid.” It is surrounded by the astragalus, navicular, cuneiform 1 and the claw-like piece... G. R. Waterhouse (A natural history of the Mammalia, Vol. 11, Pl. 18, Fig. 4) gives an excellent figure of the tarsus of Cerco- labes nove hispane, but he calls these elements “supernumerary bones ” (pp. 405—406). Let us examine the relationship of this bone in some other orders 1Gegenbaur, C. Untersuchungen zur vergleichenden Anatomie der Wirbelthiere, 1 Heft. Carpus and Tarsus. Leipzig, 1864. 88 General Notes. [January, of mammals. In Hyrax I find a small bone between the astragalus and navicular, which I can only homologize with the “ sesamoid.” In the carnivores it appears to be coalesced with the navicular, as in Lepus, for I always find in the ascending part of the navicular traces of a former separation. In an embryo of a dog of 65™™ I have observed indications of a former distinction. In a recent examination of Ornithorhyncus! I have observed the same con- dition as in Cercolabes; the spur of the former is homologous with the claw-like piece in this rodent. A similar condition is found in many Edentates. The question now is, what is the homologue of this bone? I can only compare it with the tibiale. The astragalus would then be homologous with the intermedium, the calcaneum with the fibulare. I reach the conclusion: First, by the position of the piece in question; it lies in the first row of tarsal bones next to the astrag- alus; second, by the development of the tarsus of mammals. never have been able to distinguish an “intermedium ” in the sense of Bardeleben. In embryos of mammals, I have always found the astragalus composed of one piece, and I never find an element between the astragalus and calcaneum. In adult mam- mals, especially in Marsupials, I find Bardeleben’s “ intermedium ” well developed, but I only consider it a tendon ossification. The terminology of the tarsus of mammals would be the fol- lowing: Tibiale =s Sesamoid, Intermedium bs Astragalus Fibulare — Calcaneum. Centrale sets Naviculare (Navic. = Centr. + Tib.). Tarsale 1 == Cuneiform 1. Tarsale 11 = Cuneiform 11. Tarsale III = Cuneiform 111. Tarsale Iv + v Cuboideum, If we seek for connecting forms among the vertebrates below the mammals, we must bear in mind the Theromorpha from the Permian recently described by Cope, which show so many resem- blances to the mammals, especially in the tarsal bones. T do mot hesitate to consider the claw-like piece in the tarsus of Cerco- labes and Erethizon and the spur in the monotremes as the rudi- ment of a sixth toe, and would like to compare it with the same structure seen in the tarsus of frogs. In my paper on the morphogeny of the carpus and tarsus of the vertebrates I will speak further on this subject—Dr, G. Baur, Yale College Mus., New Haven, Conn., Oct., 1884.

It contains much branched forms, bearing several non-retractile polyps at the extremity of each branchlet. The polyps are provided with long acicular spicules, and branches, twigs, and septa are without calcareous deposit. Gorgonia florida Rathke belongs to this division. Another new genus Gondu, is so peculiar that it is considered the type of a new family of Penna- tulids and even of a section of the order characterized by the fixity of the rachis, the presence of long calcareous spicules and the bilateral development of the pinnules. The colony is short and without a base. The spicules have a central canal, divided into four by septa. The only species, G. miradi/ts,is of a beauti- ful orange, with dark red polyps. The remaining species belong to the alcyonarian genera Sarcophyton, Gersemia, Clavularia, Sympodium, and Haimea, the gorgonian genera Brianeum and Paragorgia, and the pennatulid genera Gladiscus, Kophobel- emnon, Leptotilum and Pinnatula. orms.—M. J. G. de Man, of Leyden, has published a mono- graph of the nematodes of the Netherlands and of France. He describes forty-three species belonging to thirty-six genera, of which twenty are new. Terrestrial nematodes can usually be found in the earth attached to the roots of damp grass, and fresh created species abound upon the filaments of Conferve and in the detritus of ponds and brooks. Crustaceans Crustacea seem to be rare in Barentz sea, for the six Dutch expeditions have only obtained fifteen species. M. Weber, in the MMederlandische Archiv fur Zoologie, gives a careful description of Glyptonotus sabini Kroyer. Fishes ——Cases of hermaphroditism among fishes accumulate. Aristotle first noticed it among the Serranidæ, and his state- ments have been since verified. The peculiarity has been observed in three or four species of Serranus, and in sixteen other species of bony fishes, viz: Box salpa, Charax puntazza, Chrysophrys aurata, Labrus mixtus, Pagellus mormyrus, Perca fluviatilis, Sargus annularis and S. saloaini, Scomber scomber, Gadus morrhua, G. merlangus, Lota vulgaris, Solea vulgaris, Clupea harengus and Cyprinus carpio. The majority of these species are Physoclysti, but three are Physostomes. He hro- ditism has also been observed among the Chondrostei (Acipenser huso, A. sturio), but not among the elasmobranchs or the dipno- ans. In examples of Centrolophus pompilio, Smaris alcedo, and Ophidium barbatum, a mass of ovules has been seen to develop as the male gland in the midst of the spermatoblasts. M. Weber (Ueber Hermaphrodismus bei Fischen. Nied Tijd. vor der Dierkunde) gives an interesting anatomical de- scription of twò hermaphrodite fishes, a perch and a cod. He attributes hermaphroditism to the primordial sexual indifference go General Notes. [January, of the materials at the expense of which the genital glands are developed. This makes it possible that, while one part of these embryonic materials evolves the male sex, the other may suffer modifications in the direction of the female. Reptiles —The lizards of the genus Macroscincus, which are not known to occur on any other spot than the desolate volcanic islet of Branco, three and a half miles south-west of Santa Lucia (Cape Verde islands) are said by M. A. Milne-Edwards to be exclusively vegetable feeders of exceedingly timid disposition. They live in holes among the loose basaltic masses which strew the island. The largest example obtained by the naturalist of the Talisman was sixty centimeters in length. irds.—The report of the committee for obtaining observations of the migrations of birds at light-houses and light-vessels aroun and near the British islands, contains much interesting informa- tion. Light-vessels moored from five to fifty miles off shore are most favorably placed for such observations. At Heligoland, the rush of migrating birds is more marked and concentrated than anywhere onthe English coast. The great rushes on the English east coast in 1883 were on September 21 and the two following ` days, with moderate cross-currents of air blowing over the North sea, on October 12 and 13, and from the 27th to the 31st of the same month. No less than eight Greenland falcons were shot on the west coast of Ireland during the past year. Not a tithe of the enormous immigration of the autumn returns by the same lines in the spring. Mammals.—M. A. Milne-Edwards stated in 1871 that, as a result of an examination of the foetal development of Indris, Propithecus, and Lemur, he had concluded that the lemuroids had incontestable affinities with the herbivores. Since that epoch, . Milne-Edwards has examined the embryos of Microcebus, Galago, etc., which yielded the same results, and lastly has dis- sected a foetus of the aye-aye. This was found to resemble in every essential character those of other lemuroids, while the foetal membranes were those of a typical lemur. The dentition of the: young aye-aye is much less different from that of other lemurs than that of the adult, in consequence of the shedding and non-replacement of some of the milk-teeth. The abnormal characters of the species are developed as age advances. EMBRYOLOGY:.! AN OUTLINE OF A THEORY OF THE DEVELOPMENT OF THE UN- PAIRED FINs OF Fisnes.2—The median fins of fishes normally present five well-marked conditions of structure which corre- spond inexactly to as many stages of development, which, in typi- 1 Edited by JOHN A. RYDER, Smithsonian Institution, Washington, Di ti * To appear in full in the Proceedings of the National Museum, with plates. 1885. ] Embryology. 9I cal fishes, succeed each other in the order of time. A sixth ex- ceptional form is developed in consequence of an extensive degeneration of the chordal axis and hinder end of the urosome, unaccompanied by an upbending of the hinder end of the axis, as in the case of the evolution of heterocercy. The most prim- æval stages, or those found to appear in the younger phases of the growth of fishes are somewhat approximated by the structure of the fins of some of the most ancient Devonian, Triassic and Jurassic forms and by such living forms as Chimæra, the Dipno- ans and Leptocardians, but the parallelism of the development of the tail of young fishes with the successive modifications of caudal structure found in the forms of ‘successive geological periods is not.exact, as we shall presently show. 1. Archicercy—The most primitive modification of the urosome is that which I will call avchicercal, and which is without any median fin-folds whatsoever. While it is true that only a few de- generate or specialized forms of true fishes (Hippocampus, Nero- phis) approximate such a condition, it must be admitted that the fins are acquired structures, and that the folds from which they are developed have been acquired in the course of the evolution of the ancestry of the fishes. When a young fish is developing in the egg its tail grows out at first as a blunt prolongation back- wards, which is for atime wholly without fin-folds, cylindrical and vermiform in general appearance, with the muscular somites clearly marked. - The larva of Branchiostoma (Fig. 1) is at first without median fin-folds, and that of Petromyzon seems to be without them during the very early stages, and while we must make due allowance in both these cases for the effects of degeneration, we may, I think it probable, look upon these types as possessing at one stage a typically archicercal and vermiform tail. The solitary Urochorda or Ascidians pass through an archicercal stage of development of the urosome. In the course of further development the As- cidians never seem to pass beyond what I have called the second or lophocercal stage when it is absorbed in the caducichordate forms, but persists in the same stage in the perennichordate Ap- pendicularia, . The Elasmobranchs seem to pass through an archicercal stage while the Amphibians do not exhibit it in so pronounced a way, very soon becoming lophocercal, though the larva of Dactylethra has the anterior part of the urosome with high median fin-folds while the termination is somewhat like that of C/iimera monstrosa (Fig. 2), but tapers more and is typically archicercal (teste, W. K. 92 General Notes. [January, Parker). After the absorption of the lophocercal tail of anurous amphibian larvæ has been in progress for some time, it seems to Fig.2 tend to lose its median folds somewhat and revert to the archicer- cal condition. This is also the case with the young of most Urodela as they approach maturity. 2. Lophocercy—The second stage of development of the median fin-system of Ichthyopsida is what I have called /ophocercal (= protocercal, Wyman; = /eptocardial, A. Agassiz) when it con- sists of continuous folds (Amphibia, Elasmobranchs, Teleosts, etc.), or exceptionally of discontinuous folds (Siphostoma, Gam- busia) which do not include permanent rays. The continuity of the median fin-fold in young fishes seems to depend somewhat upon the extent to which the permanent fins are approximated in the adult. Several forms amongst the Clupeoids develop an ex- panded eradiate caudal fold, with the chordal axis dividing it into equal moieties, which anticipates the form of the outwardly homo- cercal tail of the adult. At the close of the lophocercal condition the ray-bearing fishes at once diverge from the rest of the Chor- data, and also the Urochorda, in that they develop embryonic rays in definite regions of the median fin-fold or continuously through- out its entire extent and which give rise to the rays of the dis- tinct or continuous fins of the adult. The intervening parts of the fold in the first case atrophy (—local reversion to archicercy), Fig. 3. a”. tee TEE OE a ay oe 5 DE ae J EEEIEE SSS : D font = AY fa Enn ay, D g5 6 . = Se zan LEM a AE m m m m AE s fl SLS am 73% a a R EERS, D) Fogh Pe auu rar SISE the materials for the formation of the rays being supplied par- tially by mesoblastic secretion, while the axial parts are of meso- blastic origin; the materials for the medulla of the rays being supplied by the outgrowth of mesoblast into the fold. The dis- position of the materials for the development of the rays of the unpaired fins seems to be very decidedly under the control of heredity, which determines their permanent location or position in E a NE ge 1885.] Embryology. 93 the primitive fold, which may therefore be considered the matrix of the permanent fins In the formation of rays, their supports and musculature, there is clearly a close correspondence between the number of ray- bearing somites of the body and the one, two or three rays and supports which are developed to each segment, and this is mani- fested even when heterocercy and its accompanying degenerative processes manifest themselves in the caudal region of the most specialized forms. 3. Diphycercy—The most archaic distribution of the median fin-rays is a continuous one, (as in Fig. 4), and is hypaxial from the vent to the end of the tail and then forward dorsally or epaxially ; (Ccelacan- thi, Placodermi, Dipnoi, Pleuracanthus). Another archaic trait is the perfectly “ straight chorda or vertebral axis which 7S extends without upward curvature in ` typically diphycercal forms to the end of the urosome. (An archaic trait which also marks a phase of the ontogeny of the Teleosts is the Ceela- canthous—hollow—condition of the bony portion of the spines and their supports.) Fishes with a long eel-like body have tended to remain diphycercal, while those whose bodies have been abbreviated have tended, with the exception of such forms as the Heterosomata, to develop discontinuous median fins which have very probably been derived in the first instance, from hyper- trophied portions of a continuous series. This hypertrophy in some cases involved the whole series, e. g., Platax. The prime- val pre-diphycercal or lophocercal condition is mediately followed by the next stage (Fig. 5) which, as we have seen, must have been developed from a more archaic condi- tion or one of true diphycercy. There therefore occurs a more or less extensive elision or failure to develop a continuous i of median fins. Embryonic mene rage — Mhs therefore fails to exactly recapitulate the phases of evolution of the median fins. Even the embryonic rays which are of mesoblastic origin do not always form a continuous series. They are far more numerous than the permanent rays, and are characteristic of the diphycercal condition and rep a stage of fin development which may be called the protopterygian These views are fully substantiated by the development of the caudal skeleton of the eel, in which in spite of its slight hetero- 1 Another article in the succeeding number will deal with the origin of the fin- rays. Gk General Notes. [January, cercy the diphycercal continuity of the fin-series has remained practically unimpaired, thus affording the necessary proof of the serial homology of the entire series of median fin-rays and their intermediary supports. (Previous authors failing to attack this part of the problem by the light of the ontogeny of a diphycer- cal eel-like type have missed the solution of one of the most im- portant minor parts of a rational theory of the median fins, since it is otherwise impossible to prove such a homology in forms with atrophied intervals between the vertical fins.) The meso- blastic ‘skeletogenous tract from which the median fin-rays. and their supports are developed, is continuous in the median line of the urosome, above, below and almost over the end of the chorda in fish embryos; such a continuity affords an explanation of why the median fin-rays form an uninterrupted series in cases of per- fect diphycercy (Fig. 4), or where the archaic has not been re- placed by a specialized mode of development, in the course of which discontinuity has arisen (Protopterus). 4. Heterocercy—Heterocercy affects only the end of the chor- dal axis, which is bent upwards, and as a result of this it and the subsequently formed terminal vertebral segments are consolidated into a urostyle (many Teleostei), above and below which epaxial and hypaxial skeletal elements are formed, of which the former are, however, often aborted, and the latter widened as supports for the caudal system of rays. is condition appears to result from two causes: (1) Great activity of growth in the terminal hypaxial part of the primitive caudal fin-fold in consequence of which the chorda is shoved up- wards ; and (2) from the actions of the animal in using the result- ing expanded, hypaxial, caudal, ray-bearing fold in swimming ; the strokes of the fin in action, owing to the resistance offered by the water, tend to throw up the somatic axis, just as an oar tends to be thrown upward in sculling. Since the hypaxial fold may be developed at some distance from the end of the tail, in the more specialized forms (Lepidos- teus, Fig.6; Gasterosteus) a more or less extensively free portion aS, 2RR ot the lophocercal caudal axis is left to project (Fig. 7) during the growth of the true or secondary caudal, the rays of which are mostly hypaxial and serially homologous with those of the anal. The exserted part of the larval axis alluded to above, may be called the ofzsthure, in reference to its position in relation to ` 1885. | Embryology. = the permanent caudal. It subsequently degenerates, or it may persist as a prolongation of the chordal axis covered by integu- ment, as in Chimera monstrosa (Fig. 2) or, as in heterocercal Amiurus (Fig. 8), it may, at an early stage, have the chorda ex- serted beyond the last hypural car- , Es tilages and at some distance behind “sy/ them have another hypaxial car- / CANNE tilage (of) developed, which may be called opisthural, as it probably rep- resents the remnant of proximal hypural pieces, which were devel- oped in some more primitive ances- tral form in which diphycercy was more pronounced or even perfect. Where the caudal, ray-bearing fin- fold is developed nearer the end of the chordal axis (Apeltes, Siphosto- ma, Gambusia,) heterocercy is not so pronounced, as the urostyle is shorter and only one or two of the terminal vertebre are involved, whereas in other cases (Salmo, Lepidosteus) more terminal vertebrze may be implicated by degeneration. In archaic forms of heterocercy there may be epaxial rays and intermediary supports developed, while the hyp- axial supports and rays extend to the end of the upwardly bent termination of the axial column (Fig. 5). This trait may possi- bly differentiate the archaic type of heterocercy (Palzoniscus, Platysomus, Acipenser, Squali) from the more recent or special- ized form (Amiurus, Fig. 8) now prevalent amongst Teleosts, and which have for the most part a more or less well-developed uro- style, but with a very short or included opisthure (= dorsal lobe, A. Agassiz), and with the epaxial spines of the urostyle displaced, rudimentary or aborted. Outwardly homocercal Palzeozoic fishes (Dapedius, Pycnodus,) probably had an opisthural filaments de- veloped during their larval stages which subsequently became aborted, as in Lepidosteus, but in others (Platysomus, Pygopterus,) the terminal part of the chordal axis doubtless became segmented, the segments bearing hypaxial caudal rays and few or no epaxial ones, so that their opisthures were probably rudimentary or wanting. It thus becomes evident that the development of modern Tel- eosts presents only a partial or inexact parallelism with that of the Palæozoic Rhomboganoidei, for few, if any, of these forms show the urostyle so distinctly developed or the hypural pieces so ex- tensively codssified as in existing Teleostei, and we have also shown that there is no such thing even as an exact parallelism to be discovered between the development of the tail of the embryos of the latter and that of the embryos of an existing representa- tive of Palaozoic forms, viz., Lepidosteus (Fig. 6). The Rhom- 96 General Notes. [January, boganoidei, Cycloganoidei, Crossopterygia and Chondrostei show a more decided tendency towards the development of a dorsal and ventral, or, only a ventral series of caudal rays which extend to the end of the caudal axis, and thus trend more towards a diphy- cercal condition than the existing Teleostei, which may be said to be verging towards hypocercy when all of the caudal rays will be of hypaxial origin, with very often a rayless interval between the last hypaxial pieces and the end of the exserted urostyle (Fig. 8), the latter finally tending to become shorter and be aborted as in : Fistularia and Apeltes. These are some of the marks of pro- gress which distinguish the Teleosts and supplement the signifi- cant fact of their well-ossified skeleton. It is highly probable that we shall find no remains of the larvz of Paleozoic fishes in the rocks, so that we have no means of contrasting their early phases with those of existing forms, but it is certain that none of the most simple forms of the Palzozoic fishes, in respect to their caudal skeletal structure, even approximate such a primi- tive condition as the lophocercal stage of modern forms; the only trait which they possess in common are the continuous me- dian fins ; in the first instance containing rays, in the latter case being without them. When we know the larve of Ceratodus, Polypterus, Lepidosiren and Protopterus, as well as we know that of Lepidosteus we may have a moderately comprehensive under- standing of the main features of the development of Palzeozoic hes. The evidence in favor of degeneration of portions of the cau- dal region of fishes is the existence of a permanent archicercal opisthure in Chimera monstrosa and Stylephorus chordatus ; the extensive development of a temporary opisthure in Lepidosteus ; the concrescence of the hypural pieces; the ventrally diplacan- thous and even triplacanthous caudal vertebre (Fig. 8), or their coalesced representative, the urostyle ; the existence of hypaxial opisthurai elements; the abortion of the epaxial spines of the caudal vertebra, and finally the abortion or extreme modification of the last muscular somites of the caudal region. 5. Homocercy—This merely expresses the condition of epaxial and hypaxial symmetry presented by the fan-shaped caudal of Teleosts, and is the final term in the evolution of the growth of the rays of that fin, in consequence of which the archaic symme- try of perfect diphycercy becomes again restored, though the axial structure of the tail is heterocercal. 6. Gephyrocercy.—This type of tail appears to be normally met with in only two forms of Teleosts, viz., Mola and Fierasfer. The primitive opisthure or end of the urosome in these forms is apparently aborted, in the first, in the course of larval existence, in the other during post-larval life. As a result of this a hiatus is left between the epaxial and hypaxial rudiments of the median fins, and in the center of this hiatus the axial column ends netted TREY SU iS 1385] Fhysiology. | 97 abruptly as if cut or bitten off, the hinder hypaxial and epaxial tissues concerned in the formation of rays and their supports are then approximated over the end of the aborted axis so as to form a continuous chain, and developed later than the other and more anterior median fin-rays (Mola), and the interval so bridged by a secondary process of development leads to the formation of what we may call a gephyrocercal tail, in which the spinous axial apophyses of the caudal vertebra, together with their centra, fail to develop, and the caudal rays rest either upon interspinous ele- ments alone, or even these may be almost entirely aborted, as is the case for a time in the young stages of Mola “ Ostracion boops No and “ Molacanthus,” both of which are evidently young, post- larval phases of that form. The views here outlined rest partly upon facts of my own observation, but I must express my great indebtedness to the researches of L. and A. Agassiz,Vogt, Lotz, Balfour, Parker, Hux- ley and Kölliker, whose labors have enabled me to coordinate the facts and establish doctrines respecting the origin of the median fins, which are founded upon the theory of ontogeny. — John A.

THE PRESENCE, SOURCE AND SIGNIFICANCE OF SUGAR IN THE Bioop.—Seegen publishes an interesting contribution to the much discussed question of the function of the liver in relation to car- bohydrates. As is well known, Bernard and his followers re- garded the liver as the sugar-making organ, and went so far as to maintain that the sugar thus formed was produced chiefly by the disruption of albuminous material. Pavy and others regard, in general, the liver as a sugar destroyer, by whose means the over- loading of the blood with absorbed carbohydrate is prevented. Seegen lends his support to the older school. He shows that sugar formation in the liver is a general physiological function shared by widely different groups of animals, herbivorous and carnivorous. He finds, moreover, that the liver,even when excised, has the power of producing sugar from peptone. Numerous researches on dogs gave the following principal results: 1. Sugar is a normal constituent of the blood, but varies in its proportions from 0.1 per cent to 0.15 percent. 2. The sugar content of the blood in the right and left sides of the heart is the same. Dif- ferences between the proportion of sugar in arterial and venous blood are not constant but yariable within narrow limits. The blood of the portal vein, however, nearly constantly contains less sugar than that of the carotid artery. 3. The blood which léaves the liver contains double the quantity of sugar held by that entering it. The mean of thirteen experiments gave for blood of the portal vein, sugar O.I 19 per cent ; for the hepatic vein, sugar 0.23 per cent. 4. The amount of sugar thus leaving the liver in the course of a day is very considerable. The amount produced by the dog’s liver in twenty-four hours is calculated to vary from 200 to more than 400 grammes. 5. The blood-sugar is formed, at least in carniv- orous animals, exclusively from albuminous bodies. 6, The sugar content of the blood rapidly diminishes when the liver is excluded. This sugar is used up in all the living tissues.— Phliigers Archiv, Bd. 34, S. 388. THE PREVENTION oF HypropHopia.—MM. Pasteur, Chamber- land and Roux have made the following communication on the prophylaxis of rabies by inoculation with a modified virus. They find (1) that the virus transferred from the dog to the ape, and cultivated by propagation through several members of the latter order, becomes progressively feebler after each inoculation. After a certain period of such cultivation, if it be hypodermically administered to dogs, guinea-pigs or rabbits, or even by intracra- 1885.] : Psychology. 99 nial injection (the most deadly method), death does not result, but the animal acquires an immunity from hydrophobia. (2) If, on the other hand, the poison of rabies be cultivated in suc- cessive rabbits or guinea-pigs only, its potency is intensified, and after a time is so great that a fatal issue invariably follows its inoculation. The ‘poison as found in the dog is intermediate in strength between that of the two methods of cultivation just mentioned. Thus by careful selection of the medium and the stage of cultivation, it is possible to accumulate a store of attenu- ated virus which can be relied on to communicate a modified rabies whose inoculation shall be protective against its severer forms, as that of vaccinia is against variola. There is also good reason to believe, though the actual experiment is postponed, that, as with vaccinia, the modified poison hypodermically en- grafted immediately after the bite of a rabid animal, will forestall, by the speed of its development, the symptoms due to the bite. No experiments have as yet been made on the human subject. (Progrès Médical, May, 18834). The experiments which M. Pasteur is reported thus far to have made are said to be an un- broken success. Fifty-seven dogs have been the subjects of investigation. Of these, nineteen were rabid, and by these, thirty- eight healthy animals were bitten under uniform conditions. Of the thirty-eight, one-half the number had been previously inocu- lated or “ vaccinated ” with attenuated virus, the other half had not. The latter, without a single exception, died with unequivocal signs of rabies, whereas the nineteen others remain as well as ever. They will be watched for a year by veterinary surgeons to see whether the inoculation holds good permanently or only tempo- rarily. If rabies be not spontaneous in its origin, and if the experiments of Pasteur all turn out successful, there seems no reason why canine madness should not be extirpated from our midst.—Lancet, Fuly 12, 1884. PSYCHOLOGY. CLEVENGER ON THE EvoLuTion oF Minp AnD Bopy oF MAN AND Animats.'—We have here a work, scientific and speculative, on several of the live questions of the day. The author is an evo- lutionist physical and metaphysical. More than this, he is a mechanical evolutionist, and endeavors throughout the book to prove the origin of structures through use and effort, and their loss by disuse. The especial object of the discussion is to dem- onstrate the origin of mind and its various departments by the action of its material basis. From this ape he does not ex- l EEEE Physiology and 1 Pcholgy by S. V. Clevenger, M.D., Chicago, Jansen EE & Co., 1885, pp 100 General Notes. [January,: our own. Forthwith we must assign it a desire for food, which desire is the chemical affinity of atoms; then the Amceba hun- gers.” The origin of movements under the stimulus of pain and pleasure is next followed out. The reproductive instinct is referred to as a modified form of hunger. There is also a theory of the origin of the brain; and another as to the origin of the differentiation between the motor and sensory nerves and their functions. The work is a brilliant one, and is studded with epi- grammatic sentences, some of which have points which will be felt, but whether pleasurably or painfully will depend on the opinions of the reader. For instance ; “ Sociologically the money- grubber devours the services of men of brains, and the issue of the business is the development of faculties and facilities for mercantile improvement both in the sordid and mental aspects.” Again: “ A Chicago writer dislikes to credit any one in Arkan- sas with a good thought. A New York or Boston man cannot conceive of Chicago originating anything, and across the sea the general run of scientists avoid any mention of America or its workers if possible. Darwin was a notable exception to this rule, for he was above pettiness.” The author has ransacked the liter- ature of his subject, and has made a most interesting,book. he writer undervalues metaphysics, which he calls “lunar _ politics.” Hence his identification of consciousness with chemi- cal affinity (see above on hunger). This is a fundamental point in the science of mind in the large sense, though it may not greatly affect theories of the evolution of the human mind out of consciousness with the aid of memory and molar motion. We have already explained in this journal (1884, p. 973, on Catagen- esis) and elsewhere the opposite doctrine, that consciousness is not a form of energy, but that although inseparably bound to matter and energy, it is coéqual with them. Some reasons for this view may be restated as follows: When a form of energy is developed (as heat, light, etc.), which was not present before, we know, in accordance with the law of the conservation of energy, that the energy was already present in some other form. We thus get something out of something. We cannot hold the same view when consciousness ‘appears where it had not been before. It is like the attempt to add beans and potatoes to get apples, etc.; in a word it is an attempt to get something out of nothing. To look upon it asa product of the metamorphosis of energy is like regarding a man as the product of the door which is opened in order to admit him to sight. None but a savage could entertain such an opinion. In view of the nature of the case, as well as of the truths of Kinetogenesis, so well presented by Dr, Clevenger, it is much more logical to believe that the consciousness is derived from an outside source, and is communicated to matter which is in a proper energetic state. The difficulties in the way of this view are largely if not °1885.] Psychology. IOI entirely removed by the well-known facts of discontinuous con- sciousness. There is a form of brain malady in which persons whose consciousness is clearly continuous to outside observers, lead two or more distinct conscious lives, the one of which knows nothing about the other. This is caused by the abolition of the memory of a part of the conscious existence. Now it is far more probable than not, that in a transfer of consciousness from one physical basis to another, the molecular structure which is the condition of memory is lost in whole or in part. Hence the ab- sence of prenatal memory. If the mind ever learns of its for- gotten life it must be by a process of exploration and unraveling of records. Such a research would be a paleontology of mind, and its materials are doubtless as abundant in the universe as are the records of the physical organisms which we now excavate from the rocks.—&. D. C. A Horse's Memory.—Our sagacious little family horse—“ Joe” —was kept at our place a few weeks one winter several years since, and then taken back to his owner, thirty-five miles away. wenty-one months later I purchased him. He was led to town by the stage-driver, where I received him a mile and a half from my farm. I saddled and mounted him and told him to “ go,” leaving him, however, to take his own course, with a view to see- ing whether he remembered the way home. Several turns were to be made in the village streets in getting out of town, but Joe made every one as correctly as he would to-day, after having traveled the same little journey daily for years. We finally crossed a bridge over Boone river, at the west end of which a gate opens into a grove, the house being forty or fifty rods off to the north. Joe stopped at the gate of his own accord, waiting for me to dismount and open it. He seemed to know every rod of the way, both to the barn and the stable, though he had been away about a yearand nine months. He was a little disconcerted, however, upon going into the stable, appearing lost fora moment, but the cause of his embarrassment was sufficiently apparent from the fact that the stalls had been changed to the opposite side. It was perfectly clear, however, that he had not forgotten a single detail of his daily life during his first brief sojourn with us.—Charles Aldrich, Webster City, Lowa, Nov. 21, 1884. TRAINING ELEPHANTS.—African elephants, said Forepaugh to a reporter, are more intelligent, imitative and cunning than the Asiatic. In training elephants the best method is to win them over by petting and feeding them with something nice. Ialways have a cake or some delicacy to give one of them when I take him out for practice, consequently the beast is always glad to see me, and is more attentive and docile than he otherwise would be. Elephants never forget anything—they recollect “their stage business ” and “situation,” and do not vary an inch one evening 102 General Notes. [January, from another in taking their positions. It requires about five months to train an elephant. We practice from 6 o’clock in the morning until 6 o’clock in the evening. They are drilled singly, and then in squads, and then taught their various “ specialty ” acts and tricks. Elephants are more imitative than any other animal perhaps, and are very cunning. While practicing they are looking out for an opportunity to “cut up,” and wil reach back and kick the trainer, and then look as innocent as a truant school-boy. They seem almost human enough to talk. The importation of elephants has increased tenfold within the past decade. Ten years ago very few circuses had more than three or four elephants, and one was the usual number ; now, no circus is complete without fifteen or twenty —LZxchange. THE CHIMPANZEE IN CoNFINEMENT.—At the Zodlogical Gar- dens, Philadelphia, are two interesting individuals of this species. Although they are comparatively young, perhaps not older than six years, yet they have an extremely antiquated appearance. I heard a countryman say to a bystander that he “ guessed they were 70 years old, easy.” One of them has such a great fondness for an old blanket that he carries or drags it with him wherever e goes. Even if he desires to climb to the extreme top of his cage, the blanket must go along, although it greatly retards his progress. He knows its use, but does not always use it judiciously. Thus, on an oppressively hot day in July, I have seen him reclin- ing for twenty minutes or more, entirely enveloped in the blanket, with the exception of his face, looking at the spectators with a comical and pouting expression. I saw one, when teased and dis- appointed by its keeper, throw itself upon the floor, and roll and scream vehemently, very like a naughty child in a tantrum. A board shelf was placed across their cage for them to climb upon. This they soon found could be used as a spring-board, and nothing seems to give them more pleasure than, when there is a good audi- ence, to steal gently to the center of the board, grasp it tightly with all fours, and spring violently up and down, causing the board with themselves to vibrate rapidly, and producing at the same time a loud, jarring noise. They then seem to greatly enjoy the startled and amused looks of the spectators. Perhaps one of their most human actions is languidly to recline, and holding a straw in one hand, listlessly to chew at its tip, while the eyes are rolled vacantly around. It may be that they are then building “ castles in Spain.” —C. F. Seiss, in Scientific American. ANTHROPOLOGY.! THE PRECURSOR OF Man.—At the meeting of the French As- sociation at Rouen, last year, the section of anthropology made an excursion to Thenay, near Blois, to study the question of Ter- tiary . The digging was performed under the direction of 1 Edited by Prof. Oris T. Mason, National Museum, Washington, D. C. 1885. | Anthropology. 103 MM. d’Ault-Dumesnil and F. Daleau.

On the one hand there is nothing sacred about him, and he may have to be knocked on the head; on the other hand, he is not, per se, as a rival of “ Tertiary man,” to be hustled off the wharf. INTERNATIONAL GEOGRAPHICAL ExposiTion.—-At the seventh National Congress of French Geographical Societies to be held in Toulouse in next August, will be organized an international exposition, of which the fifth section relates to anthropology.

Considerable space has been given to these programmes be- cause the time has come to give to our science a more restricted definition in the use of terms and the classification of objects. In other words, we ought to know what terms to apply and what arrangements to make of our specimens, to exhibit and to describe them. The Naturatist will open its anthropological department for the discussion of these two ideas, the meaning of words and the best methods of classifying. The last point will include the number and relative importance of classific concepts as well as the method of separating and studying materials, 104 General Notes. [January, Turner’s SAMOA.—Readers of books often wish that authors would so concentrate their writing as to tell just what we want to know and not one word more. This is unreasonable; but, on the other hand, most authors write a great deal that is never quoted by anybody. Twenty-three years ago George Turner published his celebrated work, Nineteen Years in Polynesia, in which he mingled his experiences as a missionary with ac- ` counts of the natives that our greatest anthropologists were never tired of quoting. In the volume now before us the ethnographic matter has been extracted, much new matter has been added, and the whole has been so arranged and indexed as to constitute a text book on Polynesia of the highest order. Dr. E. B. Tylor endorses the work in an appreciative preface. The first two chap- ters relate to the Samoan group and the traditions of their ori- gin and names; the third, fourth and fifth to the religion and the gods of the natives. . The rest of the chapters take up the gen- eral subject in the following order. The people: infancy, child- hood and adult years; food, cooking, liquors ; clothing ; amuse- ments; mortality, longevity, diseases; death and burial; houses; canoes ; articles of manufacture; government and laws; wars; the heavens and heavenly bodies ; origin of fire and other stories; names of the islands illustrating migration ; political divisions ; ethnological notes on Bowditch, Humphreys, Mitchell, Ellice, Tracey, De Peyster, Spieden, Hudson, St. Augustine, Rotch, Hurd, Gilbert, Francis, Netherland, Savage, New Hebrides, Loy- alty, New Caledonia and New Guinea islands. One hundred and thirty words are given in the following fifty-nine languages: Marquesas, Tahiti, Hawaii, Raratonga, Manahiki, Samoa, Niué, Fakafo, Tonga, Bau, Rotuma, New Zealand, Aneiteum, Niua Tanna, Eromanga, Vaté, Nengone, Lifu, New Caledonia, Ebon, Moreton bay, Malayan, Javanese, Bouton, Salayer, Menado, Bolanghitano, Sanguir, Salibabo, Sulu islands, Cajeli, Mayapo, Massaratty, Amblaw, Tidore, Gani, Galela, Liang, Morella, Batu- merah, Lariko, Saparua, Awaiya, Caimarian, Teluti, Ahtiago and Tobo, Ahtiago, Gah, Wahai, Matabello, Teor, Mysot, Baju, Dorey, Pt. Moresby, Madagascar. Whatever other book the ethnographer may have to do with- out, he cannot afford to deprive himself of this concentrated treatise. SNAKE DANCE OF THE Moguis.—Three years ago, that prince of collectors, Col. James Stevenson, sent to the National Mu- seum a large collection of rudely-carved and painted dolls, wands, head-gear, blankets, rattles and other paraphernalia relat- ing to the Moki sacred dances. Following him, Mr. Cushing, who understands very well the purport of these objects, mounts them for the great exposition at New Orleans; and to cap the climax, Captain John G. Bourke, U.S.A., writes a charming book describing the manners and customs of the Moki, their seven 1885.] Anthropology. 105 communal towns perched upon the mesas of Northeastern Ari- zona, and relates with great minuteness his attendance upon the snake dance, a rite which seemed revolting even to the enthusi- astic narrator. Everybody should read the book. We do not know which to praise the most, the author for shaking off the lethargy of camp life and gathering the material, the happy, often frolicksome style in which the work is written, or the beautiful illustrations which throw so much light upon the text. We have only space here to say that in the month of August every year the Moki celebrate a snake dance. Eight days before the dance the young men go north one day, west one day, south one day, east one day, and the other four days they roam all over the country, if necessary, to catch the snakes, using all kinds. These reptiles are placed in an estufa until wanted, kept in order by certain old men who have no other weapon except a small stick, at the end of which are two eagle feathers. The snakes are afraid of the birds of prey, and seem to have a wholesome dread even of their feathers. After the most elaborate preparation, witnessed by Captain Bourke, the dancers march through the principal streets, certain of them carrying each a squirming snake in his mouth, the animal being kept in order by a companion using the eagle-quill teaser. The closing chapters of Captain Bourke’s volume are devoted to the daily life and customs of the seven Moki towns. Way TroricaL Man 1s Bracx.—Dr. Nathaniel Alcock con- tributes to Wature a very interesting paper in which he argues that light and actinism have codperated with heat in the coloring of the skin. If man could live by heat alone, in the tropics the black man would be fittest, because he would be the hottest. But light has also played such an important part that those in whom a portion of the rays of the glaring sun are blocked at the sur- face are best adapted for survival beneath its vertical beams. The waves of light and heat follow each other at similar rates through the luminiferous ether. When light or heat impinges on man its _ waves select those atoms whose periods of vibration synchro- nize with their own period of recurrence, and to such atoms de- liver up their motion. It is thus that light and radiant heat are absorbed. Heat waves thus notify their existence along the sur- face fiber to the central nerve cell, and so enable the animal to avoid their action, if excessive, or seek their increase if deficient. While heat waves are thus received and responded to, their fel- low workers, the waves of light, are not inert. Admitting that theoptic nerves are but nerves of the skin, whose molecules once could vibrate only with the large ultra-red waves of heat, it must be conceded that in the first instance all surface nerves must have felt the influence of that agent by which they are to be hereafter exalted. But a yet more wondrous les- son is to be learned from the steps which nature takes for the 106 General Notes. [January, exaltation of a heat-responding nerve into one capable of vibra- ting in harmony with the shorter waves of light. In the Euglena viridis a colorless and transparent area of protoplasm lies in front of the pigment spot, and is the point most sensitive to light. Progressingupward we ever meet with the same arrangement, transparency immediately in front of the part to be exalted, and pigment immediately behind it. Nature has made the most of her two factors by exposing the selected tissue to the continued impinging of waves of light, at the same time securing not only the transmission through it of the waves of heat, but their constant accumulation behind it, thereby causing the molecular constituents of the protoplasm to be thrown into the highest rates of vibration possible with the means at disposal. Recognizing the effects of simultaneous light and heat when their influence is concentrated, by a local peculiarity, on a partic- ular part, must it not be evident that in an individual unprotected by hair and unscreened by clothes, living beneath the vertical rays of an equatorial sun, the action of these two forces playing through a transparent skin upon the nerve endings over the entire surface of the body, must be productive of intense, but at the same time disadvantageous nerve vibrations, and that presumably such individuals as were least subject thereto would he best adapted to the surroundings. Nature having learned in ages past that pigment placed behind a transparent nerve will exalt its vibrations to the highest pitch, now proceeds upon the converse reasoning, and placing the pigment in front of the endangered nerve reduces its vibrations by so much as the interrupted light would have excited, a quantity which, though apparently trifling, would, when multiplied by the whole area of the body surface, represent a total of nervous action that if continued would soon exhaust the individual and degrade the species. Thus it is that man still retains in its full strength the color of skin which, while it aided him materially in his early escape from his enemies, is now continued because it has a more im- portant office to fulfill in warding off the millions 6f vibrations a second which would otherwise be poured in an uninterrupted stream upon his exposed nervous systen.—Nature, Aug. 21,84. MICROSCOPY. Mopern Metuops oF Microscoricat REsEARCH.—Microscop- ical technique has made such rapid progress in the last few years that it has been found necessary to supplement our hand-books of methods through the publication of special journals and depart- ments of journals which undertake to bring together the latest discoveries and improvements. A new and very important line of 1 Edited by Dr. C. O. WHITMAN, Mus. Comparative Zoology, Cambridge, Mass. 1885. ] Microscopy. 107 work has thus been started, and this work is destined to grow rapidly in general importance and interest. It may be worth while to consider briefly the character and the urgency of such work, and to suggest how its aims can be promoted by those who are actively engaged in the various fields of microscopical research. The microtome has come to occupy a place in the zoological laboratory second in importance only to the microscope itself. Many improvements in details and in accessories have followed the introduction of this instrument, and a whole series of methods has sprung up in connection with its use. In short, we have a new art which has been appropriately called mzcrotomy. The general favor with which the microtome has been received is the best evidence of its usefulness. There ought no longer to be any place for prejudice or indifference in regard to its merits. The use of the instrument is so simple and the methods connected with it so easily acquired that no naturalist can afford to work without it. It is not enough to possess a microtome and to be master of its simpler uses; the working naturalist should have the best, or one of the best instruments in the market, and it is important that he should have the earliest information of any improvements number of new preservative and staining fluids have been de- scribed; and new methods of killing, hardening, preserving, ‘ staining and imbedding have been recommended. The rapi development of methods is at once the result and one of the chief causes of the increasing activity in every field of biological re- search. The improvement of methods leads to the re-investiga- tion of old subjects, and at the same time prepares the way for attacking new problems. The investigator who neglects to keep himself informed of the progress in methods of study, throws away his opportunities, and has the vexatious mortification of seeing himself outdone and his work superseded by that of more skillful hands. : So much depends on successful methods of preparing objects for investigation, that naturalists are now expected to state pre- cisely how their results have been obtained. But the methods 108 : Scientific News. (January, are usually given .with the investigations themselves, and are therefore scattered about in different journals and isolated publi- cations; hence arises the necessity for some sort of repertory in which the stray accounts and straggling items may be gathered and summarized. The department of microscopy will make this work its special concern. The necessity for immediate informa- tion makes it impossible to avoid a more or less chaotic presenta- tion of subjects, and reviews of progress in special directions will therefore be in order from time to time. There is another feature of the work proposed in this depart- ment to which we wish to invite particular attention. Experience has shown that each different object requires a special mode of treatment, and that the same object must be treated differently according to the nature of the problem in hand. For example, the course of preparation which has given satisfactory results in the study of the development of the ova of a certain species, may prove quite inadequate when applied to a different though closely allied species. And it has been found that different stages in the development of the same ovum often require different modes of preservation. The investigator cannot, therefore, blindly adopt the methods employed by others, but must, in by far the greater number of cases, determine by experiment the method to be pur- sued. But such experiments demand a general knowledge of methods, and, above all, a knowledge of the special applications of methods in cognate subjects. It is in the adaptation of meth- ods to special subjects that the skill of the investigator is shown. Our information of the methods employed in specific cases should be as extended as possible. To meet this need entire courses of methods that have led to successful results in typical cases will continue to find a place in this department. uch then are the aims of “ microscopy.” If those who take an active interest in the cultivation of microscopical methods de- sire to further these aims, they can do so, and at the same time confer a favor, by communicating to the editor any information respecting methods which they have found useful, or by sending | published accounts of important methods for review in these pages. sA’ sVe SCIENTIFIC NEWS. — The winter session of the Teachers’ School of Science con- nected with the Boston Society of Natural History commenced in October with a lecture on sponges, by Professor Alpheus Hyatt, who will conduct a course of ten lessons upon the structure of ani- mals. The plan pursued by Professor Hyatt has special reference to the teaching of methods of observation. On. Jan. 3d will be commenced a supplementary course of ten practical laboratory 1885.] Scientific News. 109 lessons in elementary mineralogy, to be given in the laboratory of the institute by Professor W. O. Crosby and Mrs. Ellen H. Rich- ards. The class is limited to fifty teachers, one to be nominated by each of the masters of the Boston grammar schools. — The Biological School of the University of Pennsylvania was opened on Nov. 3d. Professor Harrison Allen delivered the opening address. He outlined the objects of the school in a mas- terly manner, pointing out that original research is its leading aim. It is to be hoped that Professor Allen’s views as to its conduct will be carried into effect, otherwise it will become a school of in- struction only, and as such an unnecessary addition to the gen- eral university course.

Enormous numbers are fed to eels, which greedily devour them. In one pond they were said to consume seven hundred and fifty horse-feet in three days. It would seem impossible to furnish so many, but the number does not begin to detail the extent of the catch. Millions of them are annually fed to swine and poultry, and some men make a business of catching them.

This gentleman remarked that the limestone of the peninsula is eroded into numberless caverns, and is full of sinkholes, yet when exposed it is hard and in some localities marble-like. He believed that sea- urchins cannot have protection in view when they cover them- selves with sea-weed, as they are more conspicuous thus covered. e common Busycon pyrum of the coast always deposits its eggs below the sand, attaching the egg-cases to a shell at least eight inches below the surface. Two mollusks, Fasciolaria tulipa and Melongina corona, break holes in the shields of king-crabs and eat out the flesh. Saw-fishes are abundant in shallow water, and it was observed that when they were speared they would turn up the saw and pull it repeatedly across the handle of the spear, soon making a notch. The sand of the beach is siliceous, and is probably derived from the mainland of Georgia. Mr. Potts stated that he had received several fine fresh-water sponges from the St. John’s river, near Palatka. One of these he believed to be a new Meyenia, for which he proposed the name suddivisa.

The same speaker called attention to the dis- covery, by Mr. Alan Gentry, of spiders in full health and activity beneath the surface of the ice of a frozen pond; when found they were passing from point to point on lines stretched between water plants at a distance of eight or ten feet from the bank. Dr. Leidy exhibited specimens of FPentastomum proboscidium from the lungs of a Florida rattlesnake. Mr. Potts announced the discovery of great numbers of Cristatella in Harvey’s lake, near Wilkesbarre. Specimens six inches long were found. In traveling they did not follow the sinuous course usual in the genus. The colonies have a persistent non-polypiferous appendage. As a provisional name he proposed Cristatella lacustris, May 22.—Mr. Willcox stated that shell-mounds abound on the west coast of Florida.

Professor Heilprin announced that in addition to the foraminifer- ous genera previously described (Orbitoides, Nummulites, Oper- culina, Heterosteginz, Biloculina, Quinqueloculina) he had found Spheroidina in the rock-masses from Florida. He believed that none of the genera save Orbitoides had before been found in America. He had found a second species of Nummulites, also one or two additional forms of Orbitoides, one of which (O. ephip- pium) proves beyond doubt the Oligocene age of the deposits.

OUR species of Arvicolinz have been found in Southeastern Indiana, and it is to certain observations of the habits of these that your attention is called. The species referred to are Synap- tomys cooperi Bd., Arvicola pinetorum LeC., Arvicola riparius LeC., and Arvicola austerus Ord. The latter is the rarest species, and A, riparius is by far the most common. The credit of the discovery of Cooper’s field mouse in Indiana belongs to that pioneer of Western naturalists, Dr. Rufus Hay- mond, who, in 1866, sent an alcoholic specimen of this mouse from Brookville to the Smithsonian Institution. Dr. Haymond says of this specimen: “I think it was in June, 1866, that I dis- covered this mouse about a mile north of Brookville. I thought it a common meadow mouse (A. riparius); when caught I put it into an old leather purse in which I had previously confined a small shrew. When I reached home I found the shrew had killed the mouse; the little murderer Soon fell a victim to the law of blood revenge, and was packed with its victim in a jar and sent to the Smithsonian Institution.” This mouse is numbered 9963 in the Smithsonian collection. No other specimen was taken in Indiana for several years. In 1879 one of the writers took the second specimen found in this State, about three miles below Brookville and four miles from where the first one was taken thirteen years before. Specimen after specimen followed this one, all being taken from the same locality. From the most reliable information obtainable, we conclude 1 Read before the section of eet! A. A. A. S. at Philadelphia, Sept., 1884. VOL, XIX.—NO. II, 114 The Habits of some Arvicolne. [ February, that less than fifty specimens of this little mammal have ever been taken, of which number more than half have been secured by the writers from this same locality. This mouse is found on hillsides in high, dry, blue grass pas- tures, where flat stones are irregularly scattered over the surface ; it especially prefers what are known as “ woods pastures,” con- taining little or no undergrowth. The locality whence Dr. Haymond obtained his specimen is a hillside pasture field, with no trees, sloping towards the east. The greater part of the other specimens have been taken from a steep rocky hill sparsely covered with timber, known as “ Brown’s hill.” Cooper’s field mouse has been found breeding from February to December. It has never been known, by the authors, to bring forth more than four young atatime. In all suckling females which have been brought to our attention the mammez have appa- rently been but four, one pair pectoral and one pair inguinal. Dr. Coues says (Monographs of N. A. Rodentia): “ In No. 9963 (Dr. Haymond’s specimen) apparently a nursing female, we find two pairs of pectoral mammz and one pair of inguinal mamme, without being able to make out any intervening ventral ones. It is probable, however, that the species possesses a ventral pair, making eight teats in all.” In this matter, from the light we now have upon the subject, we are not able to coincide with Dr. Coues in his views. In young specimens the hair appears finer, shorter and more glossy than in more aged examples. As a rule the specimens just reaching maturity are darkest, but one old female shows a very dark reddish-brown back, and is dark ash below. If there is any difference in sexual coloration, the females are slightly the darker. The nest of this species is always under cover, generally in a hollow log or stump, and is composed of fine grass. It is not so securely built as the nests of some of the other species of this family. Cooper’s mice live in winter chiefly upon the stems of blue grass and the more tender portions of the white clover. Stores of these foods may be found near their winter quarters, In No- vember, 1883, a large quantity of the tuberous roots of the plant commonly called “wild artichoke” (Helianthus doronicoides Lam.) 1885.] The Habits of some Arvicoline. 115 were found in one of the store-houses of a colony of these mice. These mice vary much in numbers in favorable localities in different years, but it is questionable whether this variation is from migration or irregular causes. In 1879 they were very common on Brown’s hill, many of them frequenting the remains of an old stone mound. No other species were commonly met with in this locality at the same time. This year no examples of S. cooperi have been taken on the top of this hill, but a single specimen was found at the base of the hill. Since Dr. Haymond took his specimen north of Brookville no other example has been found in this direction from town, although sought for at differ- ent times, Cooper’s mouse is the most active representative of its family in this locality, It is most frequently found by turning over stones and logs, beneath which it remains concealed, especially in winter. Upon removing their covering, as the light reaches them, they are off like a flash for their subterranean paths, leav- ing the collector to mourn for a valuable specimen, a glimpse of which he caught as it fled betore his hand could grasp the prize. Another interesting representative of this family is the pine mouse (Arvicola pinetorum LeC.). This species has generally been considered rare in this locality, but in a two hours’ hunt last February eleven specimens were taken by the writers. Several specimens have also been captured by a cat within a little more than a year. Dr. Coues aptly says in his Latin description, “forma quasi- ` talpoidea ;” the species strongly resembles the mole in form, espe- cially in the size of its fore feet and in the strength of the forward part of its body, and also in its habits, The runways of the pine mouse are nearly always under ground, sometimes an inch or more beneath the earth, the line of which may easily be traced by the upheaved earth. The locality where the pine mice, to which reference has just been made, were taken, has long been a favorite place for the mice-catchers of the local society of natural history to find Syz- aptomys cooperi. On this particular occasion but a single speci- men of this interesting species was taken, while almost a dozen examples of a species which had previously been regarded as rare were found in its accustomed haunts. 116 The Habits of some Arvicoline. [February, These examples were taken from the higher part of a steep, partially wooded hill. They apparently sought the west and south-west sides, where they were found beneath leaves, logs, stumps and stones. Upon the covering being suddenly removed they appear dazed, affording for an instant an opportunity to cap- ture them; should the first attempt prove futile, they seek safety in the first available hiding place, but when frightened from here, hasten through their labyrinthic underground passages and are seldom seen again. Of their breeding habits we have noted nothing. Asa rule the pine mice winter in a last summer’s nest, which is a round ball of blue grass blades, from four to six inches in diameter ; the interior is composed of fine grass which is nicely bound together with longer blades. The nest is generally placed beneath a pile of leaves or an old stump. In winter collecting single specimens are generally observed occupying these old nests. ; The pine mouse, in winter, lives upon the tender roots of young hickories, the young sprouts of the white clover ( Trifolium repens), the fruit of the red haw (Crategus coccinea L.) and the tuberous roots of the wild violet (Viola cucullata Ait.). The first of these he uses for luncheon while excavating his runways. It is never found stored in his burrows, but as his passages approach these roots they expand, laying bare a large portion of the root from which the bark is generally entirely removed. The other products we find buried, the latter in numerous deposits, some of which contain a gallon of tubers and extend eighteen inches be- low the surface of the ground. This latter article evidently forms the bulk of their winter food. The common meadow mouse (A. riparius) is the most common mammal in Southeastern Indiana. It varies in numbers with the seasons.. Some years the fence rows of wheat and barley fields are traversed by a. network of their runways. In autumn, after the frost has cut down the more tender parts of the weeds and grass, numbers of these little rodents may be seen darting. here and there through their half-covered passages. In winter they are warm friends of the farmer who leaves his corn in the shock latest. After the early snows have fallen the corn shocks will be found thickly colonized by these little pests, who find here not only a comfortable residence, but also a well-filled granary from which to draw their winter’s food. In spring, when the last snows 1885. ] The Habits of some Arvicoline. 117 have disappeared, one will observe where the meadow mice have advanced their passages very near the public thoroughfare, while the neighboring pastures and commons show many traces of their highways. Their food in winter is the corn found in the thriftless farmer’s shocks, together with the seeds of a number of plants and the young blades of the blue grass. Their large round nests are also constructed of the blades of this and kindred grasses. They are built much after the manner of musk-rat houses, a mini- ature of which they closely resemble. : The single opening is below, where it connects with the run- ways of the animal. These nests are found in almost every con- ceivable place : in thickets and brier patches among the rank grass which grows there, in swampy places upon a tussock of grass, in a log or fence corner, under a pile of rubbish and very many on the open ground, especially in clover meadows, where the mice may prey upon the nests of the humble-bee. The meadow mice breed from February to December. A suc- cession of favorable or unfavorable circumstances, as the case may be, causes either an abundance or scarcity of specimens. This mouse has an ingenious and patient method of securing the head from a standing stalk of grain. Selecting a stalk which gives promise of a large well filled head, the mouse cuts it off as high up as it can reach ; owing to the proximity of the surround- ing grain the stem will not fall, the butt end drops to the ground and another cut is made about four inches up the stalk; the pro- cess of cutting off sections of this length is repeated until the grain is within reach. Here, after a square meal, the mouse leaves a collection of straws about four inches long together with a shattered head of grain to puzzle the farmer. Arvicola austerus, called by some authorities “prairie meadow mouse,” is the rarest of all our mice here. We think Dr. Lang- don very properly calls this species the “wood mouse,” on ac- count of its attachment for the more open woodland or the grassy fields or newly cleared land adjoining such. All the specimens taken here have been captured by a cat, hence we are umac- quainted with its habits. Owing to the fact that all of these species live in summer sur- rounded by luxuriant vegetation, much less is known of their summer habits than of their life in winter. The species with which we are best acquainted occur at times eh 3 118 On a Parasitic Copepod of the Clam. [February, in great numbers, while other years they are very scarce. During the years 1878 and 1879 Arvicola riparius was very common and could be found in every locality, but in 1880 most of them disap- peared, and for a long time they were very scarce. They have slowly increased in numbers and are now as numerous, perhaps, as ever. Whether these strange reoccurrences are the result ot migrations or disease we are, from the present state of our know- ledge, unable to determine. Mice have their enemies, as do most other animals. They are caught in large numbers by the smaller hawks (Zinnunculus spar- verius Vieill, Accipiter cooperi Bp., and Accipiter fuscus Bp.), owls (Scops asio Bp., and Asio accipitrinus Newton); cats and dogs catch them as opportunity affords. Many also are killed by their curious little enemies, the shrews. In habits no two of the species named approach each other very nearly except in general characteristics. They all appear to be gregarious, living as a rule in colonies. The pine mouse burrows deepest, and makes the most lengthy runways. The passages made by Cooper’s field mouse are never of much length, but are very sinuous and intricate. In food each species appears to partake of some particular kind or kinds found near the local- ity it-frequents. Except in case of the pine mouse and Cooper’s mouse the localities occupied by each species do not appear to overlap, each frequents a peculiar kind of region wherein it plays its part in the economy of nature. ON A PARASITIC COPEPOD OF THE CLAM. BY PROFESSOR R. RAMSAY WRIGHT. INCE the researches of Dana, published between thirty and forty years ago, comparatively little attention has been given to the Copepoda in America. So much is this the case that Gerstzcker in his account of the geographical distribution of the order, mentions only sixteen species as inhabiting the fresh waters and coast region of North America, the described forms being all fish parasites. Of late, however, important contribu- tions to the knowledge of the fresh-water, free-living forms have appeared in this journal, and new parasitic species have been 1 Bronn’s Thierreich, Vol. v, c. 1876, p. 799. 2S.

IIQ added by Kellicott! and myself? to the list of those already de- scribed. That much remains to be done in this direction may be gath- ered from the common occurrence in the gill-tubes of the ordi- nary long clam (Mya arenaria) of an interesting form, so large as to occasion surprise that it has hitherto escaped notice. At the recent meeting of the Am. Assoc. for the Advancement of Science in Philadelphia, I proposed the generic name Myicola for the copepod in question, and shall describe the species as M. metisiensis, from the village of Little Metis, on the Gulf of St. Lawrence, where the specimens were taken. The order Copepoda affords most interesting material for the study of various grades of parasitism. At one end of the series are the completely free forms, at the other the completely para- sitic, in the adults of which it is often impossible to recognize any resemblance to the copepod type. But no important gap exists in the whole series. Even among those with well-developed jaws (Gnathostomata of Thorell) the Notodelphyide only occur as commensals in the branchial sacs of tunicates, while before we reach the completely parasitic forms, where the mouth is con- verted into a sucking tube (Siphonostomata),’we find a large number of forms (the Poecilostomata of Thorell), some free and some semiparasitic, where the parts of the mouth are evidently formed for piercing soft tissues and thus obtaining fluid nourish- ment. To the last section belong the Coryczidz, Sapphirinidz, Lich- omolgide, Ergasilide, to which groups some authors accord family rank, while others are disposed to regard them as consti- tuting a single family (Coryczide). It may be stated generally that while the fish parasites are chiefly Siphonostomata, and the ascidian commensals chiefly Notodelphyidz, the copepod para- sites of the other groups of the animal kingdom—Mollusca, Vermes, Echinodermata, Ccelenterata—are largely Poecilosto- mata. Thus members of this group have been found on the gills of cuttlefishes, on the delicate branchie of nudibranchs, in similar situations on marine annelids and holothuroids, and on the soft tissues of sea-pens and other ccelenterates. The clam parasite also belongs to the same group, as do all 1 Proc. Am. Soc. Micros., II and Iv. 2 Proc. Can. Inst., N. S. Vol. 1, p. 243. 120 On a Parasitic Copepod of the Clam. [February, the Copepoda parasitic on Mollusca with the exception of the Penella larve found on the gills of cuttlefishes, the Artotrogus from the egg-sacs of Doris, and certain species of Splanchno- trophus, which bore into the skin of nudibranchiates. Hitherto, so far as I have been able to determine, only three cases of Copepoda parasitic on lamellibranchiates have been re- corded, viz., Authessius solecurti Della Valle, on the external sur- face of Solecurtus strigilatus) Modtolicola insignis Aurivilius, from the gills of Modiola vulgaris and Mytilus edulis? and Pac- labius tumidus Kossmann, from the pericardium of Tridacna (Phil- ippines),? I have not had access to the description of the last- named form, which belongs to the Ergasilide, and, according to Aurivilius, shares the great development of the cephalothorax, the absence of appendages on the fifth segment and the long egg- sacs with the genus Ergasilus. The two other forms are closely related to Lichomolgus, and.apparently still more closely allied to each other, for a comparison of the figures shows that their most divergent characteristics, the mouth parts and the fifth pair of thoracic appendages, do not present greater differences than are to be met with in the range of the genus Lichomolgus.! Further investigation will show whether it is desirable to retain them in separate genera. It will appear from the following generic diagnosis of the clam parasite that it occupies a position intermediate between Licho- molgus and Ergasilus: i Myicola, n. g.—Cephalothorax of Q oblong, of oS pyriform, composed of six seg- ments, the last of which is reduced in size and carries a pair of uniramous appen- dages.

In the proportionate size of the thoracic segments, the position of the mouth and the conformation of the natatory feet, it approaches on thé other hand the Lichomolgide, and especially those forms already found in Lamellibranchiata.- The dimorphism of the cephalothorax, which is more striking than in any of the allied genera, is no doubt to be attributed to the cylindrical form of the water-tubes of the gills in which the females live. If Lichomolgus and the Saphirinidz be merged into the family Coryceidz, as seems the most natural arrangement (cf. Claus, Lehrbuch der Zoologie, p. 554; and Brady, Zoology of the Challenger expedition, Vol. vit, p. 109, e¢ seg.), then the exist- ence of the above described genus renders imperative the accept- ance of Della Valle’s proposal to include Ergasilus in the same family (Z c. p. 83). So extended, the family of the Coryceide would embrace some free and some semiparasitic forms, some parasites of pelagic animals, and a few whose females at least are constant parasites of Pisces, Mollusca, Vermes and Ccelenterata. The following description of the species will, with the help of the figures, serve to elucidate its most important characteristics: Myicola metisiensis, n. sp.

In addition to these changes, when several galls are found on the same petiole (Fig. 3) this is often so much twisted as to bring them on the upper side of the leaf. The galls are elliptical in shape, the longer axis varying in length from 3™ to 15™™ and the shorter from 1™™ to 8™™ From above they appear slightly convex ; their centers are hairy and purplish-red in color and set in a green ring which is continued below into the petiole. Their average height is about 1o™™ In appearance they are not “unlike buttons which have their tops mounted in metal holders. The under surface of the gall is similar in general outline to its upper, as it abruptly contracts before passing into the petiole (Fig. 4), sometimes nearly clasping it either in the direction of its long or short axis. When several galls grow on the same petiole they may either run together or be entirely separate. If they coalesce great changes in size and shape are produced. The normal petiole is usually horizontal, but sometimes twists the leaf half way round (herbarium specimens). The cross sec- tion of the petiole near its base is of a reniform shape on account of a crease in its upper surface. The crease disappears further from the base of the petiole, which then appears elliptical in cross section. . The fibro-vascular bundles of the normal petiole of the walnut are such as are ordinarily found in the stems of dicotyledonous plants. The bundle is better developed as the apex of the petiole is approached. Even here, however, the bast is more abundant than the corresponding wood. An examination of that part of the petiole where the crease has disappeared shows a second row of well developed fibro-vascular bundles. Almost no trace of this can be seen in the lower part of the petiole (Fig. 5). Under a low power of the microscope a longitudinal radial section of that part of the gall near the pith of the petiole resem- bles a drawing of a geological section of the earth in which the strata are very much bent and folded (Fig. 10). The cells them- selves are bent, but the folding takes place mainly between con- tiguous cells. In comparing cross and longitudinal-radial sections of the gall (Figs. 9 and 10) the bast is found to be quite as abun- dant as in the normal petiole, but is spread over a wider area- The wood, too, is as scanty as before. The tracheary vessels have almost entirely disappeared. Tracheids have not only 138 A Botanical Study of the Mite Gall [ February, supplied their place but mainly compose that part of the gall that is made up of folded tissue. Two or three layers of the pitted cells near the pith are wider than long and regular in shape. As the distance from the pith increases the cells increase in length and decrease in breadth until they are two or three times longer than broad. Owing to the crowding to which they are exposed, they become irregular in shape nearer the surface of the fibro-vascular bundle. In the normal petiole the cells overlying the fibro-vascular bundle are longer than broad, regular in shape and contain but little protoplasm. The corresponding part in the galls is made up of much larger cells, irregular in form and filled with a granu- lar substance which is slightly colored yellow by iodine, and red by eosin. Clustered and glandular hairs are found irregularly distributed over the petiole. The clustered hairs (Fig. 6) are found abun- dantly on the upper side of the petiole near its base. From this point their number decreases though there are still more on the upper side of the petiole than on the lower. They originate from cells of the epidermis which have crowded together in papilla- like masses, But one hair arises from each cell. Each papilla may have but one hair, though it will often have nine or ten. The ordinary number is five or six. The hairs themselves are one-celled and pointed toward the apex. At the extremity their walls are so thickened as to nearly obliterate the cavity. They are thinner towards the base, and iodine shows protoplasm to be present. The glandular hairs vary in shape. Ina general way they are made up of several cells, the terminal cell being larger than those below, and secreting an “acrid aromatic” substance. Iodine shows that there is protoplasm in their cells. These glandular hairs arise from single epidermal cells which are separate from each other by two or three intervening cells, The galls have no differentiated epidermis. Certain cells which from their position would be called epidermal are without proto- plasm, but in other respects resemble those beneath. From nearly every one of the epidermal cells cylindrical, one-celled hairs arise (Fig. 8). These hairs seem to be a continuation of the epidermis, They are about 1™ in length and ṣẹ ™ in diameter, that is, at least twice as long and broad as the normal hairs.

If this is removed the cells are found to contain a large quantity of a brown granular substance. The hairs of the gall are so unlike normal hairs in shape, position, contents and origin that they can scarcely be looked upon as modified trich- omes. Ensconced among the hairs which are distributed over the surface of the gall are found the eggs of the mite which pro- duces it. In order to know the changes which the gall has undergone in reaching its mature state, it would be necessary to make a careful study of the specimens of the gall from its first appearance to its full development. I hope to do this in the future. Possibly it may not be too presumptuous to venture a few predictions founded on a comparison of the gall with the normal. petiole in regard to development: 1. The gall must have started very early. The fact that the gall hairs cannot be looked upon as modified trichomes has been already referred to. Vestiges of the normal trichomes would be found among the gall hairs if the petiole had been far enough ad- vanced for them to appear, but no such remains are found. The epidermal cells of the gall are so thin-walled and so unlike the thick-walled and regular epidermal cells of the petiole in form, that they could have originated from them only at an early period. Comparison of the tissue beneath the epidermis in the gall and petiole does not suggest that one was derived from the other. 2. The development was doubtless inward, the stimulant, no matter of what nature, acting on the outside. The position of the eggs, the mode of oviposition of mites and the fact that no sign of their having pierced the tissue can be found, suggests this. The bending and folding of the fibro-vascular tissue would seem to suggest that the stimulant caused a greater growth in length than in breadth, and this produced the lateral pressure which pushed up the tissue. 3. The value of these various modifications to the mite may be seen in a general way. The hairs of the gall give the very best protection to the eggs, the parenchyma is an excellent cushion and is firmly supported by the tracheids which, with the other 140 On the Evolution of the Vertebrata, [ February, portions of the fibro-vascular systems may also serve their usual purpose of conductors of water.

I. PRELIMINARY. E attempting to ascertain the course of evolution of the Verte- brata, and to construct phylogenetic diagrams which shall express this history, among the difficulties arising from deficient information, one is especially prominent. As is well known, there are many types in all the orders of the Vertebrata which present us with rudimentary organs, as rudimental digits, feet or limbs, rudimental fins, teeth and wings. There is scarcely an organ or part which is not somewhere in a rudimental and more or less useless condition. The difficulty which these cases pre- sent is, simply, whether they be persistent primitive conditions, to 1885.] Progressive and Retrogressive. 14I be regarded as ancestral types which have survived to the present time, or whether, on the other hand, they be results of a process of degeneration, and therefore of comparatively modern origin. The question, in brief, is, whether these creatures presenting these features be primitive ancestors or degenerate descendants. In the first place let us define the meaning of the word degen- erate. - This must be done first from a structural or anatomical standpoint. Degeneracy may be defined as a loss of parts with- out corresponding development of other parts. All animals are degenerate in some respect or another, as, for instance, the Mam- malia in the small size of the pineal gland and of the coracoid bone ; so that degeneracy, as a whole, can only be affirmed where the sum of the subtractions is greater than the sum of the addi- tions. Function of the parts must, however, be consulted in this matter. We naturally regard sensibility as the highest of animal functions, and mind as the highest form of sensibility. There- fore development of organs of sensibility and sense and mind constitutes a better claim of progress than development of stom- ach or of skin. Since motion is under the direction of sensibil- ity, organs of movement have much to do with the question. When perfection in this respect conflicts with perfection of brain, in evidence of position, we naturally give the preference to the latter in deciding. Thus the ruminating mammals are much superior to man in the structure of their feet, teeth and stomach, yet we properly assign the higher position to the quadrumana and to man, on account of the superior complication of their brain structure, Palæontology has proven? what had been already surmised, at the development of animal organisms has been on lines of increasing specialization of parts. That is, in lines of increasingly perfect adaptations of structures to ends, or functions. In certain series of animals we witness steadily increasing perfection of mechanisms of the limbs for running; in others for digging; in others for flying. In the teeth we find increasing perfection of machines for grinding, for cutting or for seizing. In the brain the specialization has evidently been towards increased acuteness of perception, increased energy of action, and increased intelli- gence. Specialization does not, however, necessarily imply pro- gressive development. Adaptation may be to a parasitic or a 1 Cfr. On the Evidence for Evolution in the History of the Extinct Mammalia ;’ Proc. Amer. Assoc, Adv. Sciences for 1883. -142 - On the Evolution of the Vertebrata, [February, sessile mode of life. Such adaptation is often displayed in a very special modification of parts, as in the anterior limbs of some of the parasitic Crustacea; in the mouth parts of some Arachnida ; in the feet of the sloth, and in the jaws of the ant-eaters. Embryology has furnished, and will furnish, many important hints and demonstrations as to the true meaning of the rudimen- tary condition or absence of parts, and thus indicate the phylogen- etic connections of animals. Thus the origin of the Tunicata from primitive vertebrate-like forms would probably never have been suspected but for embryological studies; and the origin of the very peculiar order of Rotifera has been explained in like manner, But embryology has its limitations, for the transitional characters presented by embryos are only partially of the nature of a record of the structures which belonged to their ancestors in successive geological ages, and are frequently special adaptations to the necessities of their embryonic life. Such are the stato- blasts which are present in fresh-water sponges and Polyzoa, and wanting in the marine forms; and the allantois and placenta of Vertebrata, In a number of groups the embryo seems to have been more susceptible to the influence of the environment than the adults) It results that in many cases the phylogeny can only 1A remarkable instance of this state of things appears in the history of the evolu- tion of the insects, It is quite impossible to understand this history without believ- ing that the larval and pupal states of the highest insects are the results of a process of degeneracy which has affected the middle periods of growth but not the mature results. The earliest insects are the Orthoptera, which have active aggressive larve and pup, undergoing the least changes in their metamorphosis oT and never getting beyond the primitive mandibulate condition at the morphosis of the jawed Neuroptera is little more marked, and tis are one of the oldest orders.

As is well known, many imagines (Saturniidæ, Œstridæ can perform no other function, and soon die, while in “some Diptera the incomplete larvee themselves reproduce, so that the metamorphosis is never completed. This =- is parallel to that proposed by Dohrn to account for the origin of the ` Ammoccetes larval stage of the Marsipobranchii. He supposes this form to be more degenerate a its probable ancestral type in the ancestral line of the Vertebrata, as it is inferior to its own adult. An inactive life in mud is supposed by Dohrn to have been the effective cause, An inactive life on the leaves of plants, or in dead car- cases, has probably been the cause of the same phenomenon in the Lepidoptera and Diptera. 1885.] Progressive and Retrogressive. 143 be determined by the discovery and investigation of the ancestors themselves, as they are preserved in the crust of the earth. In all cases this discovery confirms and establishes such definite con- clusions as may be derived from embryology. It is also clear that on the discovery of phylogenetic series it becomes at once possible to determine the nature of defective types. It becomes possible to ascertain whether their rudimental parts represent the beginnings of organs, or whether they are the result of a process of degeneration of organs once well developed. A great deal of light has been happily thrown on this question as regards the “Vertebrata, by the recent work done in North American paleontology. The lines of descent of many of the minor groups have been positively determined, and the phylogen- etic connections of most of the primary divisions or classes have been made out. The result of these investigations has been to prove that the evolution of the Vertebrata has proceeded not only on lines of acceleration but, to a much greater extent than has been heretofore suspected, on lines of retardation.’ That is, that evolution has been not only progressive, but at times retro- gressive. This is entirely in accord with the views-derived by Dohrn from embryology,? who, however, wrote only of the origin of the Vertebrata as a whole and not of its divisions, excepting only the Leptocardii and Marsipobranchii, that is, of the sand lance and the lampreys and hags. The demonstration of such relations for the higher Vertebrata is now done nearly for the first time?

NATURALIST, Dec., 1884. I here remark that my researches have now, as I believe, disclosed the ancestry of the mammals, the bird, the reptiles and the true fishes, or Hyopomata, including the spe- cial phylogenies of the Batrachia and Reptilia, and some of the Mammalia.

S. Geol. Survey W. of 1ooth Mer., G. M. Wheeler, 1877, IV, 1, p. 282. ; 144 On the Evolution of the Vertebrata, [February, there remain the following: the Pisces, Batrachia, Reptilia, Aves and Mammalia. The Mammalia have been traced to the theromorphous reptiles by the Monotremata. The birds, some of them at least, appear to have been derived from the Dinosaurian reptiles. The reptiles in their primary representative order, the Theromorpha, have been probably derived from the rhachitomous Batrachia. The Batrachia have originated from the sub-class of fishes, the Dipnoi, though not from any known form. I have shown that the true fishes or Hyopomata have descended from an order of sharks, the Ichthyotomi, which possess characters of the Dipnoi also. The origin of the sharks remains entirely obscure, as does also that of the Pisces as a whole. Dohrn believes the Marsipobranchii to have acquired its present characters by a process of degeneration. The origin of the Vertebrata is as yet entirely unknown, Kowal- evsky deriving them from the Ascidians, and Semper from the Annelida. The above results I have embodied in the folowing — diagram : Aves Mammalia Reptilia Hyopomata Batrachia Pisces | Selachii Ichthyotomi Dipnoi | Holocephali Marsipobranchi Leptocardii Accepting this phylogeny, it becomes possible to determine the course of development first of the whole series ; and sec- ondly of the contents of each class taken by itself. I will first consider the direction of the evolution of the Vertebrata as a whole. II. THE VERTEBRATE LINE. The Vertebrata exhibit the most unmistakable gradation in the characters of the circulatory system.” It has long been the 1 Proceedings Am.

System. 1885.] Progressive and Retrogressive. 145 custom to define the classes by means of these characters, taken in connection with those of the skeleton. Commencing in the Leptocardii with the simple tube, we have two chambers in the Marsipobranchii and fishes; three in the Batrachia and Reptilia; and four in the Aves and Mammalia. The aorta:roots commence as numerous pairs of branchial arteries in the Leptocardii; we see seven in the Marsipobranchi, five in the fishes (with number reduced in some); four and three in Batrachia, where they gener- ally cease to perform branchial functions; two and one on each side in Reptilia; the right hand one in birds, and the left hand one in Mammalia. This order is clearly an ascending one throughout. It consists of first, a transition from adaptation to an aquatic to an aérial respiration ; and second, an increase in the power to aérate and distribute a circulating fluid of increased quan- tity, and of increased calorific capacity. In other words, the cir- culation passes from the cold to the hot-blooded type coinciden- tally with.the changes of structure above enumerated, The accession of a-capacity to maintain a fixed temperature while that of the surrounding medium changes, is an important advance in animal economy. The brain and nervous system also display a general progres- sive ascent. Leaving the brainless Leptocardii, the Marsipo- branchs and fishes present us with small hemispheres, larger optic lobes and well-developed cerebellum. The hemispheres are really larger than they appear to be, as Rabl Riickard has shown’ that the supposed hemispheres are only corpora striata. But the superior walls are membranous, and support on their in- ternal side only a layer of epithelial cells, as in the embryos of other Vertebrata, instead of the gray substance. So'that although we find that the cerebellum is really smaller in the Batrachia and most Reptilia than in the fishes, the better development of the hemispheres in the former gives them the preéminence. The Elasmobranchii show themselves superior to many of the fishes in the large size of their corpora restiformia and cerebellum. The Reptilia constitute an advance on the Batrachia. In the latter the optic thalami are, with some exceptions, of greater diameter than the hemispheres, while the reverse is generally true of the rep- tiles. The crocodiles display much superiority over the other 1 Biologisches centralblatt, 1884, p- 449 VOL, XIX.—NO, 1I. 146 On the Evolution of the Vertebrata, [February, reptiles in the larger cerebellum, with rudimental lateral lobes. The great development of the hemispheres in birds is well known, while the general superiority of the brain of the living Mamma- - lia over all other vertebrates is admitted, The consideration of the successive relations of the skeleton in the classes of vertebrates embraces, of course, only the charac- ters which distinguish those classes, These are not numerous. They embrace the structure of the axis of the skull; of the ear bones; of the suspensors of the lower jaw; of the scapular arch and anterior limb, and of the pelvic arch and posterior limb. Other characters are numerous, but do not enter into consideration at this time. The persistence of the primitive cartilage in any part of the skeleton is, embryologically speaking, a mark of inferiority. From a physiological or functional standpoint it has the same signifi- cance, since it is far less effective both for support and for move- ment than is the segmented osseous skeleton. ' That this is a> prevalent condition of the lower Vertebrata is well known. The bony fishes and Batrachia have but little of the primitive cartilage remaining, and the quantity is still more reduced in the higher classes. Systematically then, the vertebrate series is in this respect an ascending one. The Leptocardii are membranous; the Marsipobranchii and most of the Elasmobranchii cartilagin- -ous; the other Pisces and the Batrachia have the basicranial axis cartilaginous, so that it is not until the Reptilia are reached that we have osseous sphenoid and presphenoid bones, such as char- acterize the birds and mammals. The vertebral column follows more or less inexactly the history of the base of the skull, but its characters do not define the classes. = As regards the suspensor of the lower jaw the scale is in the main ascending. We witness a gradual change in the segmenta- tion of the mandibular visceral arch of the skull, which clearly has for its object such a concentration of the parts as will produce the greatest effectiveness of the biting function. This is accom plished by reducing the number of the segments, so as to bring the resistence of the teeth nearer and nearer to the power, that is, the masseter and related muscles, and their base of attachment, the brain-case. This is seen in bony Vertebrates in the reduction of ~ the segments between the lower jaw proper and the skull, from four to none. In the fishes we have the hyomandibular, the sym- 1885. ] | Progressive and Retrogressive. se plectic, the inferior quadrate, and the articular. In the Batrachia, reptiles and birds, we have the quadrate and articular only, while in the Mammalia, ‘these elements also are wanting. The examination of the pectoral and pelvic arches reveels a successive modification of the adaptation of the parts to the mechanical needs of the limbs. In this regard the air-breathing types display wide diversity from the gill-bearing types or fishes. In the latter, the lateral elements unite below without the inter- vention of a median element or sternum, while in the former the” ~ sternum or parts of it, are generally present. Either arrangement is susceptible of much mechanical strength, as witness the Siiurgi fishes on the one hand, and the mole on the other.

As regards the inferior arches of the pelvis, the Mammalia have the advantage again, in the strong bony me- dian symphysis « connecting the ischium and pubis.!

[February, malian, have degenerated in every direction in the characters of the pelvis. The limbs of the Pisces are as well adapted to their environ- ment as are those of the land Vertebrata, but from an embryologi- cal standpoint, their structure is inferior. The primitive rays are less modified in the fin than in the limb; and limbs themselves display a constantly «increasing diii kornica of parts, commenc- ing with the Batrachia and ending with the Mammalia. The de- tails of these modifications belong to the history of the contents of the classes however, rather than to the succession of the iu Vertebrata as a whole. In review it may be said, that a comparison of the characters whNgh define the classes of the Vertebrates, shows that this branch of theNanimal kingdom has made with the ages successive steps of progress from lower to higher conditions.

This second great terminal moraine marks a general advance of the great ice-sheet at a date considerably later than the stage of greatest glaciation. The great terminal moraines of the first glacial epoch have been traced from Cape Cod to Ohio and Ilin- ois, but in the interior of the continent this “supposed extreme outer moraine has not been traced out.” The author believes that the western portion of what was supposed to be the great terminal moraine of the first epoch is, in Michigan, Wisconsin, Minnesota and Iowa, a part of the later moraine. pee HYATT ON THE GENERA OF FOSSIL CEPHALOPODS.— This is an elaborate discussion of the character and relations of the genera of fossil Cephalopods, the results of many years’ patient study. It appears in the Proceedings of the Boston Society of Natural History, and is preliminary to a monograph which will appear in the Memoirs of the Museum of Comparative Zoology, at Cam- bridge, Mass. Univalve shells, the author remarks, may be generally spoken of as cones, which may be either straight, curved or coiled. The larger number of the more ancient shelled cephalopods are straight cones. The young of nautilian shells are identical with the adults of the curved (arcuate) and coiled (gyroceran) and in different series repeat their forms, sutures, shell markings and the outlines of their whorl in transverse, section. “ They are in suc- cession first arcuate, then gyroceran, and lastly nautilian or close- coiled. In several series genetic lines of adult forms may be fol- lowed, which lead by gradation from arcuate, cyrtoceran forms to close-coiled nautilian shells, the whole showing a connected series- of transitions in the form and outline of section, sutures, struc- ture and position of siphon, and shell ornaments and apertures, In some cases these graded series are in’accord with the chrono- logical record, the straight appearing first, the arcuate either in company with them or later in time, and the gyroceran and nautilian latest.” The author adds that we cannot of course claim that such per- fect evidence has been found even in the larger number of series. ete E ’s OOTO) ly ee S _ phology, or what used to be called comparative 154 Recent Literature. [February, “In some of them, certainly, it is not an over-statement to say that the chronology of the evolution of form, the development of the individual, the gradations in the adults and the general differ- ential characteristics all tell the same story, and are decisive for the opinion that in all the larger series of shell-bearing Cephalo- poda, the nautilian shells belong to several distinct series and arose independently from straight cones through the intermedium of a graded series of arcuate and gyroceran or closely coiled forms. The generic terms, Cyrtoceras, Gyroceras and Nautilus are really only descriptive terms for the different stages in the development of an individual, and also the different stages in the development or evolution of the series of adult forms in time. In other words, each of these genera as now used, include repre- sentatives of all the different genetic series of Tetrabranchs, which are either young shells in the corresponding stage of growth, or adult shells in the corresponding stage of evolution.” Professor Hyatt maintains that the Nautilini were derived directly and independently from a straight cone, and that this primitive nautiline form was a close ally and ancestor of the straight orthoceran-like Bactrites of the Silurian. “ All the re- maining ammonoids are more concentrated in development, and skip the orthoceran, cyrtoceran and gyroceran stages of their evo- lution in time. They are evidently descendants of the close- coiled Nautilinidz, and the evidence here is very strong that the whole order.of Ammonoideaarose from a single organic center of distribution, the Nautilini of the Silurian. The succession in time, the evidence of gradation in structure and the development exactly accord with this statement. Nautilinidz, Goniatites, Tri- assic transition forms of Ammonitinz and the true Ammonites of the Jura form a perfect progessive series.” During the investigation Professor Hyatt has been able to add to the facts he has already brought forward in support of the law _ of acceleration, though he now prefers to designate it as “the law of concentration of development.” All the more generalized or lower types, he says, have a direct mode of development, and the more specialized or complicated progressive types have, when at the acme of their development, a more indirect mode of devel- opment.” The types which are descended from these last have often a mode of development which in many forms is an appa- rent return to the direct mode of development again.” It is impossible to farther epitomize this important paper, and we shall look forward with much interest to the complete illus- trated memoir.

The first step the student should take is to become familiar with the anatomy of a polyp, a worm, a mollusk, a crustacean, an insect, as well as a representative of each class of vertebrates. We should, as we are accustomed to with beginners, make this work comparative at the outset. We hear a great deal now-a-days of “animal morphology,” we hear less of “ comparative anatomy,” we prefer the older and less pompous term, as the tendency to extreme specialization even in animal morphology is a dangerous one. Yet it does not appear to be so to the author of the present book, The forms he described are treated as if they were so many separate creations, and this is the only criticism we have to make on a work so carefully prepared and so well proportioned. The book is designed in great part to take the place of a teacher. Now to our mind no teacher who does not in the beginning excite his pupils after dissecting one animal thoroughly to compare it in its leading features with the members of other classes, can suc- cessfully teach morphology, whose value as a discipline consists in leading the student to compare as well as observe. ew ad- ditional pages of matter would, therefore, we think, have been of > decided value in calling the student’s attention to and fixing in his ~ memory the facts concerning the resemblances as well as differ- ences in the various types he may dissect. We think this may be done without the pupil’s “losing in depth what he gains in breadth.” The list of animals selected and described in this course in zootomy is as follows: the lamprey, skate, cod, lizard, pigeon and rabbit ; if a frog, or better, a salamander, had been added, the list would have been complete, but this point has been covered by the full account of the frog in Huxley and Martin’s Biology and Gage’s account of the Necturus or mud puppy. The introduction treats briefly of the tools and methods of preparing the subjects for dissection. The two most important chapters are those on the lamprey and lizard, as the pigeon has already been well described and figured in Rolleston’s Forms of Animal Life ; and the student can easily get access to accounts of the anatomy of a fish, while the works of Mivart and of Wilder on the cat, would be more useful to the American student than that of the rabbit in this book, however excellent Parker’s de- - scription may be. , The plan of each chapter or section is excellent, the descriptions are well proportioned, the words to be emphasized are in heavy- faced type, the illustrations are well drawn and engraved, neatly lettered and fully explained. The lamprey is very difficult to dissect, and the species being the same on both continents, this 156 Recent Literature. (February, chapter will be particularly valuable to American students. The illustrations in this chapter are also very useful, the skull, with the “ branchial basket” and anterior part of the notochord being shown together, besides cuts of the brain-case from above, a full page cut of the longitudinal section of a female from the left side, showing the organs in place ; also a view of the urogenital sinus, with the rectum and part of the left kidney, with three transverse sections, one through the branchial region, another through the abdominal, and the third through the caudal ; and finally a dorsal view of the brain. The skate is a novel subject, and its anatomy is carefully de- scribed, the skeleton, venous system, urogenital organs, heart and blood-vessels, and nervous system including several views of the brain as well as the ear, being well illustrated. In like manner is the cod described and figured ; this chapter will be useful to the -American student; the cod’s skull, disarticulated, is well figured and briefly described. Fifty pages are devoted to the account of the lizard (Lacerta agilts), and this will be useful in the hands of the American stu- -dent if living south of Pennsylvania, as he can readily obtain a ‘Sceloporus or swift for dissection. The wood-cuts in this chap- ter represent the chondrocranium, the scales on the head of sev- _ eral species of lizards, the chief muscles of the ventral aspect and ` ʻa general view of the body to show the alimentary, circulatory, respiratory and urogenital organs; the latter organs of each sex are also separately figured, as well as the heart and aortic arches, while the brain in different positions is well drawn and engrave The remainder of the book, comprising the latter half, is devoted to the pigeon and rabbit.

AMERICA.— The Chilian Andes.—The account sent by Dr. Paul Gussfeldt to the Berlin Academy of Sciences, of his recent journey -in the Central Chilian Argentine Andes, contains so thorough geographical exploration than has yet been accorded to it. It appears that the lofty mountain region containing Acon- cagua, the loftiest known point in America, consists of a double range, separated, not by a wide basin or a well-defined valley, but by a trough-like depression, divided by cross ridges. The western chain is the true water-parting, and thus the eastern is broken through in many places by the water rising in the great trough between the two chains. This trough is about 185 miles long, is entirely uninhabited, and has a mean elevation of 9800 feet. The chief valleys of this region are called “cajones,” or boxes, because of their straight walls of rock enclosing them. These valley sides are formed of boulder slopes and wall-like outcropping rock, and each has its separate vegetation-zone, limited by perpetual ice. The belts of vegetation, owing to the varied local influences, are of very irregular distribution, and for 1 This department is edited by W. N. Locxrxcron, Philadelphia, a eee E 1885.] Geography and Travels, 159 the same reason the snow limit is not fixed. The diversity and richness of tint of soil and rock are material points in the land- scape. The passes over these ranges reach heights of 11,394, 11,696, 12,270, 12,303, 13,474, and 13,779 feet. The highest elevations are on lateral spurs of the chief western chain, near Valle Hermoso, at the commencement of which rises the great volcano Aconcagua, 22,867 feet high. The structure of the range, together with the wind, are forms which often simulate human figures, and are called “ Peni- tentes.” These are most abundant between 11,483 and 13,779 feet. The mean height of the snow line between 32° and 33° S. lat. is estimated at 13.779 feet, diminishing to 11,483 at 34° S. lat. Between the western cordillera and the Pacific there is an out-lying coast range. Dr. Gussfeldt and his assistant reached 21,030 feet on Aconcagua, and, though exhausted by the effort of speaking, had no flow of blood from mouth or nose. The Supposed New Island off Iceland—The supposed rtew island off Reykjanes, Iceland, turns out tobe a myth. The French war- vessel Romanche and the Danish Fy//a have carefully examined either Geirfugladraugr or Grenadeerhuen, has figured as a new island. Possibly an abnormally clear day caused the lighthouse- keeper to, for the first time, perceive an object which he has since continued to see simply through knowing where to look for it. Meade river —Lieut. P. H. Ray has made an exploration south- ward from Point Barrow along the Meade river, which he struck _ sixty milesfrom its mouth, and followed for 100 miles, until he came in sight of a low range of mountains trénding north-west and south-east, dividing the north-east water-shed from that of Kotzebue sound. The guides, fearful of imaginary enemies, re- fused to go further. The region is uninhabited, and is visited only by a few natives from Hornook and Ooglamie in pursuit of rein- er. There is no timber; a few Arctic willows on the river and 160 General Notes. [February; some coarse grass on the hummocks and along the seashore, and a dense growth of moss is all the vegetation. Lieut. Ray is satisfied that there is no open Polar sea from the fact that the temperature of the water does not alter between October and July, as it must do if a large body of warmer water existed round the pole. Lake Mistassinti—Little that is definite appears to be as yet known respecting the actual dimensions of Lake Mistassini and other bodies of water reported to exist in the north-eastern part of the Province of Quebec and in Labrador. A French mission- ary, writing in 1672, says that Lake Mistassini is “ believed to be so large that it took twenty days to walk around it.” Mr. Burgess affirms that it is 150 miles in length, and abounds in dep bogs. An old trader of the “Compagnie des Postes du oi,” who was stationed on it for several years, estimated its least width at ninety miles. The account of 1672 mentions another lake “ten days round, and surrounded by lofty mountains.” These lakesappear to occupy a depression similar to that occu- pied by Lakes St. John, Temiscaming, and many smaller lakes to the south ward, and Silurian limestone has been observed on Lake Mistassini as well as at Lake St. John. The former lake is supposed to be about 1300 feet above the sea, and the land between it and Lake St. John to the south of it, does not rise above 1500 feet, while Lake St. John is only 300 feet above the sea. The plain around Lake Mistassini is said to be very fertile. and attention has recently been called to the magnificent forests and fertile soil of the country around Hudson’s bay, to the north of it. Three expeditions have been dispatched during the past summer to explore the lake region; one by way of Lake St. John, another by the River Betsiamits, and a third from New- foundland. The last expedition has orders to land scientific observers at various points upon the coast of Labrador, where they will spend the winter. The vast plain stretching north and west of Lake St. John has a clayey soil of great fertility, and a climate equal to that of Montreal. Thousands of settlers are already there, and the dense forest is disappearing. The explorations in progress will doubtless open up extensive areas for colonization, besides adding largely to our geographical knowledge. American Notes—The articles found by an Eskimo upon a floe in Julianshaab bay appear to have been those left on the occasion when, according to the’ rt of Messrs. Danenhower and Melville, the escaping crew of the ¥eanette camped for a few days on some ice-floes. Among them are the lower part of a tent, the sides of a wooden chest, with some words in pencil written upon them, a bill of lading, a torn book of cheques, a pair of oil-skin trousers marked “ Louis Noros,” and a bear skin. The ice-floe must have drifted about 2500 miles, and as this occupied 1885.] Geography and Travels, 161 about 1000 days, we have an average rate of drifting of two and a half nautical miles per day. M. Thonar will undertake an expedition to investigate the delta of Pilcomayo, and endeavor to open up a great trade route between Bolivia and Paraguay. In this it is said that he will receive the active support of several South American governments. Drs. Clauss and Herr von der Steinen have returned to Para from a successful investigation of the tributaries on the upper right bank of the Amazon and Xingu rivers. Arrica.—Mr, O'Neill's Fourney—Mr. H. E. O'Neill, in his account of his journey from Mozambique to Lakes Shirwa and maramba, through the Makua and Lomwe countries, states that in point of geographical interest, of security, and of facility of travel, this route compares favorably with any overland route to the African lakes, The Zanzibar-Tanganyika route is occupied by lawless chiefs, who levy extortionate black-mail, the route from North Nyassa to Zanzibar has been shown by the expedi- tion of Capt. Elton to be one of great difficulty, and the old Kilwa-Nyassa route, opened up by Dr. Livingstone, now passes in great part through a deserted and desolate country, owing to the ravages of the Magwangwara, the same tribe which blocks the North Nyassa route. Native ruleamong the Makua consists of a confederation of petty chiefs, each of which is perfectly independent with regard to the internal affairs of his own state. e Makua can weave cloth, but wear so little that a palm’s breadth, forty inches long, would provide clothing for half a ozen men or women. Namuli peak and its surrounding hills, 8500 to gooo feet high, forms one of the most striking features of the country. A feeling of great reverence for particularly conspicuous hills, reaching almost to mountain-worship in the case of Namuli, exists among the Lomwe. The feeling probably arises from the fact that each of these elevations has served asa refuge to the people living near it when attacked by their enemies, The Kwilu Expedition—In human suffering and cost of life _ the expedition sent to H. M. Stanley, in 1882, to explore the Kwilu-Niadi valley, rivals that of Lieut. Greely to the Arctic. The party, consisting of seven Europeans and seventy Zanzibaris, got into difficulties from want of food at the start. Two Europeans were left behind at Isanghila, where one died. The accidental discharge of the rifle of a Zanzibari, soon after, nearly brought on a conflict with the natives. Two magnificent ranges of hills were then met with, separated by a lovely valley, watered by the Ludima, a tributary of the Niadi, which was found to be identical with the Kwilu. The first station of the association, Stephanieville, was founded near the junction of the Ludima with the Niadi. All the white men, except the leader, Capt. A. G. Elliott, were now disabled. Each of the two Belgian officers, ` VOL. XIX.—NO. II. Ir 162 General Notes. [ February, MM. Destrain and Legat, were left in charge of a station, yet Capt. Elliott pushed on, with Von Schaumann, hopelessly ill, lashed to a mule, and the only remaining officer in a deathly stupor from sun-stroke. Some time before this, a portion of the Zanzibaris mutinied, fourteen deserting, and part of the baggage had to be destroyed for want of bearers. Covered with painful ulcers, emaciated, and with bleeding feet, Capt. Elliott, when on the point of succumbing, was met by a native sent to his assist- ance by M. Van de Velde, who had been sent by Stanley to his assistance, and was at Kilabi, seven days off. Eventually Capt. Elliott and his two companions reached the coast, but Von Schauman died on the voyage home. In three anda half months only 600 miles had been traversed. Capt. Elliott subsequently explored the Kwliu river and valley in company with Mr. Spencer-Burns and MM. Mikie and Destrain. The district has for the most part been freely ceded by the natives to the asso- ciation, and formed into a province with fifteen stations. Capt. Elliott is administrator, with a staff of twenty-eight officers and about 250 men.

N., has recently traveled across . Madagascar south-west from Antananarivo. He thoroughly investigated and mapped the head-waters of the Zizibongy and its tribu- taries, and reached the coast on July 2d, after a journey of 680 miles. Then crossing the Mozambique channel in an old boat, he landed at Mozambique. Lieut. Becker will be despatched by the African International Association to cross ‘Africa and connect Karema, on Lake Tanganyika, with Stanley’s _ stations of the Upper Congo. Herr R. Flegel has returned to erlin. During the last two years he has explored all Adamawa, nd discov the course of the Binué, but the feuds and violence of the intervening tribes prevented him from journeying from the Binué to the Congo. His conviction is that the Binué is navigable for 1100 kilometers, and its chief affluents, as for instance the Taraba, for a distance of fifty to sixty nautical miles, during five or six months of the year. _ Sours Georcia.—Though in 54° 31’ S. lat., this island is by its climate antarctic.

The new genus belongs to the Oxyznidz,! and is the first one of that family that has been found in beds higher than the Bridger Eocene. The species is the largest of the Cre- odonta, and the jaw from which it is known is more robust than that of any existing carnivore. Its dimensions are about those of the Achenodon insolens of the Bridger beds, The genus Hemipsalodon differs from the others of the family in the pres- ence in the lower jaw of the full dental series of four premolars and three true molars without diastema behind the canine. In- cisors three. The only crown perfectly preserved is the last true molar. It is of the type of Oxyzna, but probably has no inter- nal tubercle (specimen worn at the point). It has a heel more or less cutting. The species is characterized by the deep compressed form of the ramus, and the long symphysis. The incisor teeth are crowded, and the canine tooth is of enormous size, and is directed upwards. The premolars are all two-rooted, except the first. The fourth is longer than the first true molar. The true OCCURRENCE OF BOULDERS oF DECOMPOSITION AT WASHINGTON, D. C., AND ELSEWHERE.—In the literature of surface geology sur- prisingly little is said of “boulders of decomposition.” This 1See NATURALIST, 1884, p. 480. 164 General Notes. [February, probably arises from the fact that such are” seldom seen 2” situ north of the southern limit of the drift, having been removed from their places of origin during the ice age. It may not be un- interesting to those geologists whose studies are in the field of surface deposits to know of a convenient locality where such boulders are even in the process of being made, as doubtless very many of the erratics, especially those of larger size, were thus produced before their subsequent transportation, as pointed out by Dr. Sterry Hunt and others. At several localities in the District of Columbia, boulders of various sizes can be seen, which to the superficial observer may be taken for drift masses, as in my own case upon earlier visits to exposed for a depth of forty or fifty feet or more. Much of the gneiss rock is disintegrated, but contains unaltered masses which have resisted the atmospheric decay. The rock is often poor in feldspar. In some places it is hornblendic. Some of the gneiss upon weathering exhibits a schistose structure, yet much is re- markably compact, but traversed by numerous jointed planes, extending in all directions. As the weathering proceeds from the jointed planes it leaves solid masses of every possible shape, from those with only the more exposed upper solid angles rounded off, through various forms where all the angles are removed, but with flat sides remaining, representing the original joint planes, to masses which are almost perfectly spheroidal, though often show- ing a banded structure. Internally some of the smaller boulders are more or less decayed, others are perfectly compact, but in digging them out there may be seen surrounding them concentric - zones, marking not concretionary structure but the progress ot Upon the sloping top of the hills there are large sized boulders ; with their angles and faces more or less rounded, and although standing two, three or four feet above the grass-covered soil of decomposed gneiss, yet their under portions, upon examination, are found to be connected with the solid masses beneath. Thus we find in every stage of production excellent examples of the genesis of large “boulders of decomposition ”— boulders not distinguishable from very many of those which have, been trans- ee oN 1885.] Geology and Paleontology. ; 165 ported great distances during the Pleistocene period. There are several localities in the District of Columbia where such boulders may be seen, but their development cannot be studied so well as in the artificial cuttings in the hillsides along the Potomac river. aving made a study of these large boulders in a state of formation, one, who is familiar with Northern erratics, is led to agree with Dr. Sterry Hunt, that at least the larger “rounded masses of crystalline rocks, left in the process of decay, consti- tute the boulders of the drift,’ and not only these but many roches moutonnées. his deduction has been objected to upon the ground that boulders generally do not continue to enfoliate. n the District of Columbia many of the boulders seen out ot the hillsides described, do not show continued exfoliation (natu- rally very slow and with the atmospheric forces removing such as rapidly as formed, where not protected) any more than many erratics, while others are more or less uniformly OT through- out the whole mass. Although very many erratics do not show regula exfoliation, yet there are numbers of places where exfoliating boulders may be found in the drift. Perhaps there are no better localities for studying these rocks than those I examined during the last two summers, in the greater drift deposits along the Mississippi river, at Burlington, Keokuk, Warsaw and elsewhere. At these places numerous northern boulders—mostly greenstones—may be found _ Of various sizes from a few pounds to a few thousand, which are now exfoliating and in various stages of decay, having forms from subangular to spheroidal. Also near the southern limit of ee drift, at Columbia, Mo., situated upon the highlands, away m the river valleys, similar examples may be found, both of pheeiikeitie and gneissoid rocks. Neither the presence nor absence of ice scratches affect the above explanation of the primary origin of these large boulders, but only represent subsequent abrasion, or the absence of that action, or else the more recent surface decay of the rocks them- selves. —J. W. Spencer, M.A., Ph.D., F.G.S. ARE THERE ANY FOSSIL ALGa ?—Mr. Lester F. Ward, in a paper read before the American Association at Philadelphia gave. some statistics of the fossil flora of the globe. Among other things he said that from the Lower Silurian there have been de- scribed species of Algæ. The question arises, what are the prob- abilities of Algæ being preserved in a fossil state ? It seems to have been the habit of geologists, almost from the time that palæontology assumed: the aspect of a science, to refer to “fucoids” or Alge many fossil markings which were evidently not animal remains. It was assumed that everything fossil must have been an organism, and it is only of late years 7 166 y ` General Notes. ` [February, that the fact has been admitted that many of these’ fucoids are in reality inorganic. Let any one consider for a moment the structure of the most of the species of modern Algze; remember how easy it is for cellular tissue to be destroyed by only a short immersion in water, and the unreasonableness of expecting to find fossil Algz will be perceived. Or again, let anyone turn, as Professor Les- quereux, for one, has done, to modern sea beaches; let him see the immense masses of kelp thrown up by the waves of every storm, and see how soon they disappear by passing “ into gelatin- ous, half-fluid matter, which penetrates the sand” (Lesq.), and he will again see how unreasonable it is to say Algz can be long preserved. Even when covered with sand, mud or clay they dis- appear and leave no trace behind them. ' Professor Hall, in the first two volumes of the Paleontology of New York, enumerates thirty-six species and varieties of these fucoids from the Trenton, Hudson River and Clinton groups. He recognizes the fact that many trails, burrows and possible water marks are preserved in the rocks, but has no hesitation in refer- ring many fossil marks to undoubted Algæ. Later writers have not been behind in naming and describing other species. In 1878 fourteen new ones were added as found in the rocks of the Cincinnati group. Recent investigations of these fourteen, and of some eighteen others reported from this group, have revealed the fact that wot a single one is an undoubted Alge, a// can be referred either to water marks, trails, tracks or burrows of different sorts, or to graptolites. : _ This statement can be proved only by comparison with marks found on recent beaches and mud flats. Sir Charles Lyell has shown how leaves, impressions of bird tracks, mud cracks, worm ` _ borings and rain-drop impressions can be and are preserved on the mud flats of the Bay of Fundy. There is no reason for suppos- ing that circumstances were less favorable during the continuance of the Silurian epoch in geological time. The writer of this has studied many recent mud marks, and has seen in process of for- mation tracks and burrows which resemble, to an astonishing degree these fossil marks. For instance, the burrows made by a species of beetle in the mud wonderfully resemble some of the fossils, Paleophycus ru- gosus, for example. The trickling of water down a sloping bank leaves traces like those which, fossil, have been called Algæ. The dashing of rain on the surface of mud leaves marks which have been compared to the roots of plants. Impressions left on mud by fragments of organisms have been described as fossil Algæ, even when not the remotest resemblance could be noted between them and any modern prototype. —Ss_ Professor Nathorst, in a memoir written in Swedish! and pub- ` lOm spar af nagra Evertebrerade rade djur M.

In this memoir he tells how certain of these marks were readily made by himself, and how many others can be identified with marks seen on ocean beaches! It is, indeed, time that this habit of referring to some sort of life every mark found in the rocks of the earth, and calling all uncertain marks marine plants, should be protested against. If it is not done the nomenclature of the science will be so encumbered with useless names that chaos will result. The multiplication of species has gone entirely too far already ; and when every mark made by a dash of water, every turn made by a worm or shell, and every print left by the claw of a crustacean is described as a new addition to science, it is time to call a halt and eliminate some of the old before making any more new species.— Jos. F. Fames. GroLocicaAL News.—/urassic—The Marquis of Saporta an- nounced to the geological section of the French Association for the Advancement of Science, the discovery of a plant bed of Jurassic age near Beaune. The enclosing rock is a fine-grained limestone, probably of the Corallian epoch. The plants are closely related to those which have been collected from beds of the same age upon the Meuse, and consist of attenuated conifers and dwarf cycads and ferns. The discovery at two points so far apart of such a starveling flora proves that it was not local, as at first believed, but was spread over a large area. Associated with these plants are some, widely-spread echini, such as Czdaris cervi- calis, C. florigemma, etc. M. Saporta has also returned to the defense of bilobites, gyrolites and other fossils, the vegetable origin of which has receatly been disputed. The Cretaceous of the Pyrenees has been studied by M. Hebert, who published the first part of his researches in 1867, and in a more recent arti- cle states that nothing has since come to hand to invalidate his previous conclusions respecting the Lower Cretaceous, which are to the effect that the Lower Neocomian is wanting, the Middle Neocomian is continuous, the Upper Neocomian occurs at many ints, and is lacking in others through denudation, and that the Gault exists both in the Central Pyrenees and the Corbiéres. The Lower Cretaceous usually abuts upon faults which bring it in contact with beds which are proved by their fauna to be Senonian, and therefore much more recent. The Lower Cenomanian ap- pears to be absent from this region, while the Upper Cenomanian lies either upon the Neocomian or the Trias, thus showing that at the time when the chalk of Rouen was deposited the Pyrenees had in great part emerged, forming an island or a series of islets in a Cenomanian sea. The Turonian is largely represented i the Pyrenees, but the almost crystalline structure of the beds is unfavora ble to palzontological researches. Bini Count Saporta has shown, in reply to Mr. Nathorst, that some of the re- i Ep. ported Algze are correctly so determined.— 168, General Notes, [February, Zertiary—Sr. Lotti (Boll. Com. Geol. d'Italia, 1884) gives a summary of his investigations into the age and structure of the granites of Elba and the surrounding districts. These granites show two principal types, granite and quartzose porphyry; the latter traverses and is involved with the sedimentary rocks of the Apennines in such a way that geologists have been compelled to pronounce it Eocene. As it is against the usual idea to refer granites to so recent an epoch, an effort has been made to finda separation between the granite and the quartzose porphyry into which it passes. This Sr. Lotti declares to be thoroughly inad- missible, and at direct issue with the facts. The feldspathic rocks graduate from a normal or tourmaliferous granite to a quartzose porphyry through varieties with or without tourmaline, but the Pre-silurian gneissic schists of the eastern part of the Elba show a gradual passage toward granite, and are traversed by granite seams. Sr. Lotti concludes that not only are the porphyry, gran- ite and intermediate varieties of the same age, but that all were formed at the expense of the gneissic schists in the Eocene epoch, while the Eocene strata were contorted and dislocated, and frag- ments embedded in the erupted mass. Quaternary.—M. A. Favre has presented the Paris Academy of Sciences with a map of the ancient glaciers of the northern slope of the Swiss Alps and of the chain of Mt. Blanc. This map in- dicates the development of the glaciers, and, so far as the scale permits, shows also the glacial deposits, erratic blocks, and mo- raines. Besides showing the direction and extension of the seven principal glaciers, M. Favre demonstrates how, on taking the. height of an erratic block above the neighboring valley, it is pos- sible fo know what was formerly the thickness of the ice over that point, and also how the slope of the surface of the ancient glacier can be determined. In this way he has determined thick- nesses of 1181, 1220 and 1235 meters. The author particularly insists upon the extension of the glacier of the Rhone, which at certain points reaches a height of 1650 meters, and for a length of 149 kilometers and a width of 45 was almost horizontal. The moraines of these old glaciers are numerous, Many are composed of clayey or marly deposits with striated pebbles and blocks of greater or less size, while others are almost entirely formed of blocks of crystalline rocks. Examples of the latter occur at Combloux and Césarege, in the valleys of the Arve, Rhone, etc. Here are blocks which contain from 700 to even 2000 cubic meters. l BOTANY.!

On the opening of the bud the almost equal anthers converge and place themselves in line across the throat of the flower. The stamens curve forward so as to come into more ready contact with the body of the visiting. bee (Fig. 1), while the style is curved backward and lies under the upper lip of the corolla. When the stamens become effete the pairs on either side diverge (Fig. 2) and bend back, stationing themselves under the upper lip while the style moves forwards, takes the place of the effete stamens and opens its bilobed stigma (Fig. 3). Such is the pro- terandry of this flower which, as most of its allies, requires the visits of bees for its fertilization. he flower is of a pale rose color, which is deeper on the upper lip. The upper and lower lips are spotted with purple, while the Fig. 1. Fig. 2. Fig. 3. Physostegia virginiana. Fic. 1.—Male state. Fig. 2.—Stamens curved back.

The lines of purple lead to the true entrance.

Foerste, Granville, Ohio. BEGINNING Botany.—In teaching botany during the past twelve or fifteen years, I have generally set students at work for several weeks, in the beginning, with specimens only. These are given each member, and he is required to investigate and report at the meeting of the class. Some of these reports are made in writing. More or less of this work is done throughout the course. It has proved very satisfactory to pupil and teacher. ' 170 General Notes. [February, In March, before the opening of vegetation, the last class of freshmen began with the study of young branches of numerous kinds of deciduous and evergreen trees and shrubs. I send you the notes of W. F. Hoyt, one member of the class. I do not know that they are any better than many others which were pre- sented: “ A comparison of the leaves, buds and young branches of the Scotch pine with those of the Austrian pine. “To a casual observer there is little difference between these two pines, but on close inspection it will be noticed that the Aus- trian bears a medium-sized cone, while the Scotch has a very small one, grown sparingly. [It was not intended to study cones at this time. “ Again, the leaves of the Austrian pine are from five to five and a-half inches long. They are thick and stiff, while those of the Scotch pine are from two to three and a-half inches long, and are quite slender and limber. In both the leaves have the same shape ; in both the leaves are in pairs, and when placed together make a long round body. The covering of the lower part of the leaves extends much farther up on the Austrian, and is of a much darker color than on the Scotch pine. “ The leaves of the Scotch pine are lighter in color; the tree and branches more slender. “The outer bark of the Austrian is thicker and darker, and the primary leaf scales shows very plainly. The leaf scales do not show plainly in the Scotch pine. Both have three layers ot bark, the outer being tough and thin, the next dark-green and spongy, the inner white; in the Austrian quite tender; in the Scotch tougher and more compact. “ As a general rule the Scotch pine sends out five branches in a whorl, while the Austrian pines show no such regularity in this respect. On cutting the limb the Scotch pine discharges more | pitch than is discharged by the Austrian pine. The wood of the Scotch pine is a little lighter in color, the rings more plainly marked and the pith a little larger.” In a comparison of the twigs of butternut with those of the epperidge, A. E. Hager observed, among other things, that the pith of pepperidge contained numerous hard transparent parti- tions. Our text-books all tell us of the cavities in the pith of butternut. _ Work done later in the course was better done—W. J. Beal. Lansing, Mich. THe Stupy oF Parasitic Funct.—One of the hopeful signs of the times, so far as botany is concerned, is the increasing interest taken in the study of the lower plants in this country. The Fungi and the minute forms of Algæ have been too long neg- lected excepting by a few lonely specialists here and there who _ quietly worked away, while almost entirely ignored by the mass __ of botanists and collectors. Now, however, the eyes of collectors, 1885. ] Botany. 171 while not less open'to the higher plants, are learning to look for plants of all kinds, from the simplest protophytes to the most conspicuous of phanerogams, We may hope some day to seea manual of botany which will include within its covers descrip- tions of all the species of the region it covers. The Preliminary List of the Parasitic Fungi of Wisconsin, by Professor Trelease, must prove a considerable aid and strong in- centive to the collection of Fungi in Wisconsin. About 270 species are recorded, a large list when we remember that it is confined to the parasitic forms only. Most of the species were col- lected about Madison by the author, and all, with but “one or two exceptions,” are preserved as herbarium specimens. Throughout the list hosts and localities are given, and in many cases these are accompanied by valuable critical notes, indicating thorough and careful work. The Peronosporez of the list number twenty-five species, of which four belong to the genus Cystopus, one to Phytophthora and twenty to Peronospora. The Perisporiaceze number twenty species, the Uredinez sixty-five (not counting isolated Uredo and zecidial forms, seven of the former and twenty-seven of the latter) and the Ustilagineæ twenty-two species.—C. Æ. Bessey. VARIATION IN CULTIVATED PLANTS.— If seed of the various sorts of the cabbage family be planted alongside each other, a resemblance is observed between all the seedlings at a certain date ; it is only as growth proceeds that the development begins to differentiate differences. It seems probable, through a study of the law of breeding, that the period of divergence marks the period at which original selection commenced in order to obtain our present forms. If this observation be substantiated, then by careful study of seedling development we shall be able to deter- mine points of departure at which human guidance shall be ena- bled to direct in line with the tendencies of the plant. This study of plant growth after the method used in zodlogy, the study of embryology so to speak, not the term “ embryology” as applied to nature’s plant but that of man’s plant, the period between the seed and the differentiation from the natural type, offers much promise of good results, and it seems quite probable that as we attempt to influence the development of the plant before or at the time of the differentiation into the acquired properties of the mature plant we can initiate a new series of selections in cer- tain varieties whose root, bulb, stem and foliage finds use.—Æ£.

Collections are required in each group, thus insuring a practical acquaintance with the plants in their native habitats—-—In the first annual report of the Wisconsin Agricultural Experiment Station, Professor Tre- lease gives accurate popular descriptions of the onion mold (Peronospora schleideniana D. By.) and the apple scab and leaf blight (Fusicladium dendriticum Wallroth). Both articles are illustrated by wood-cuts, which add materially to their value. Work of this kind is, in our opinion, much more valuable than that which usually fills the reports of these stations. We pe we could see more papers like Professor Trelease’s. May w not commend to the directors of agricultural stations the rena of the editor of Science in a recent number of that journal, in discussing the proper aim and scope of such stations: “ The great need of agriculture to-day is not new varieties of plants or im- proved breeds of animals, new methods of cultivating the soil or improved systems of farming; all these, and many other like things, are good ; but the two great wants are a better knowledge of principles and greater intelligence to apply them.” Dr. B. D. Halsted, of New York, has been elected to the chair of bot- any in the Iowa Agricultural College. The December Journal of Botany contains a fine photograph of the late George Ben- tham. e see it announced in English journals that transla- tions of De Candolle’s Origin of Cultivated Plants, and De Bary’s Anatomy of the Vegetative Organs of the Phanerogams and Ferns have recently been brought out, the former by C. Keagan Paul, London, and the latter by the Clarendon Press, Oxford. ‘De Bary’s “ Vergleichende Morphologie und Biologie der Pilze, Mycetozoen und Bacterien has just reached us, but too late for further notice at this time. It is a stout volume of 558 octavo pages and is illustrated with 198 wood-cuts. This work merits an early translation. The Fournal of Mycology, by J.B. Ellis and W. A.

NRE rior poles of the egg are determined by its position in the ovarian tubule, in which it remains during its whole course of develop- ment. 2. Segmentation and formation of Blastoderm—The segmenta- tion instead of being superficial, as usually described, is endo- vitelline. The germinal sac dissolves, and its nucleus divides repeatedly, forming a large number of nuclei within the yolk. The nuclei have amceboid movements, and go towards the poste- rior pole (PE)? and thence spread over the surface-protoplasm. A few of the nuclei remain in the center; but the great majority become distributed over the surface, where each forms a center of attraction for the protoplasm. Thus a layer of cells is formed over the whole surface, the cells being smaller and more numer- ous towards the posterior pole, which is most active in its rate of development (Fig. 1). This layer is the blastoderm. A few cells are subsequently forme lation, showing a transi- tion to epiboly, in which the peripheric protoplasm would be confined to the Fig. 1.

A single cell is given off from these, which repeatedly divides so as to become a cell-mass. These increase by absorbing food, and afterwards became invaginated as a greenish mass, called pseudo- vitellus (ps). This is destined to be received dorsally into the embryo and to become paired masses in the abdomen.

[ February, inside of the ovarian-tube cells (of) remain as an appendage to the posterior pole of the egg. 4. Formation of Germ-streak—Energetic cell multiplication at the posterior pole causes a new invagination at that place (Fig. One side of the invaginated part is of thick cells, this is the germ-streak (gs) (ventral plate of Balfour), and ultimately the em- bryo ; the other side of the invaginated part is of thin cells, this becomes the amnion (am). The blastoderm remains thin, except where it adjoins the outer extremity of the germ-streak, where it is thickened so as to form lateral plates (44). Thus embryo and amnion are both buried in the center of the egg; the embryo bends ventraliy, the abdomen curving round so as to approximate to the posterior pole, and to have appendages and amnion within its bend. The head end is at the place of invagination, lateral plates codperating with the extremity of the germ-streak towards the formation of head and brain. The central position of the embryo is characteristic of the lower orders of insects, which are therefore termed entoblastic. . These include Hemiptera, Orthoptera and probably Thysanura. AP The higher orders, as Hymenoptera, se Lepidoptera, Coleoptera, Diptera and perhaps Neuroptera, are ectoblastic, having a ventral plate formed on the surface, afterwards sinking slightly under the blastoderm, and having the anterior pole of the egg the more ac- tive. The ectoblastic condition seems to be a case of anticipation of changes Ją Which must afterwards be encountered SI by the inferior forms (see section 14 j - below). , . The blastoderm being now thin uD becomes the serous tunic around the o mo whole egg. dei oe wan Dn ea Genital Cells —A few large cells in the egg. arise at an early stage inside the blas- | toderm, near the place of invagination (ge). These come to be ultimately received into the embryo along with the pseudo-vitellus, and become paired generative or- gans, groups of ovarian tubules. | j 7. Germinal Layers—The germ-streak divides into an outer and an inner layer, each cell dividing into an outer and inner part. Thus are formed ectoderm and mesoderm (ec, ms in Fig. 3; also indicated by the dotted line in Fig. 2). The few cells formed in the center of the egg are the only representatives of endoderm. (In ectoblastic insects the mesoblast is formed by an infolding of ectoderm. 8. The appendages next show themselves, those of the head ae 1885. | Entomology. 175 arising first; and the body becomes segmented, the head having three (afterwards four) segments ; the thorax three and the abdo- men seven or eight (afterwards ten, including the telson). Thus seventeen would be the maximum number of somites of the in- sects. 9. Alimentary Canal—An invagination for the mouth is seen (stomodeum, st), and subsequently another for the anus and in- testine (proctodeum, prc). These meet each other in the body so as to complete the alimentary canal. The stomodzum forms cesophagus and stomach ; proctodzeum forms intestine and rec- tum. The mid-intestine is not chitinized, but this is related to its function and has no embryological significancy he true endoderm becomes yolk-balls, afterwards wandering cells, subserving nutrition, but not directly aiding in the forma- tion of the alimentary canal or of any other organ. The author excludes the endoderm from any share in forming the intestine in all Aithropods, if not more widely. 10, The appendages now shew their special characters. They arise by an evagination of the body wall, including ectoderm, mesoderm and part of the body cavity. Thus arise the mandi- bles and two pairs of maxilla in the head; these keep small as compared with the limbs ; the mandibles and first maxillæ after- wards combine to form a retort-like mass. The antennz arise beside the stomodzum, in the same way as the other appendages (not from the procephalic part). The EENEI segments bear pote si AARIN probably rudimentary lim The procephatic part is not originally lobed i in Aphides; it ation as an extension forwards of the antennal segment. It sub- sequently becomes pointed and forms the labrum. 12. The ventral nerve-cord arises from the ectoderm, its cells dividing so as to leave only a thin dermal layer. Transverse seg- mentation causes it to be marked off into ganglia (three anal, three thoracic, seven abdominal, which are small). These subse- quently coalesce into a subcesophageal and ventral mass The érazn is formed in the region of the lateral oni but its primitive relation to the ventral cord was not made o I ody-cavity—The general body-cavity wea ao the orig- inal segmentation-cavity. In an early stage free polar-cavities are formed between blastoderm and yolk, thus corresponding to the segmentation-cavity of lower animals. These cavities uniting insert themselves between the yolk and germ-streak, and extend into the embryo and its appendages. The same cavity spreads under the serous layer as a separate cavity. In the early stages the embryo is open dorsally, and by this route the pseudo-vitellus and generative mass find admission to its interior. Between the embryo and amnion is an “ embryonal cavity” derived from the lumen of the ovarian tube. 14. Revolution of Embryo.—When the parts of the body and 176 General Notes. {February, the appendages are well formed (after the stage indicated in Fig. 3) the whole embryo changes its position in the egg, so as to approach the original attitude of the ectoblastic embryos. The abdomen is shifted away from its proximity to the head and thorax. The head moves to the anterior pole; the abdomen to the posterior pole; the curvature of the embryo becomes changed so as to invert the relation of dorsal and ventral aspects. 15. Zrachee.—Seven pairs of minute invaginations appear on the sides of the abdomen, and afterwards two pairs in the thorax (sometimes a third in the thorax and an eighth in the abdomen, giving a maximum of eleven pairs). These are the entrances of the tracheze whose inner extremities’ are afterwards united by longitudinal tracheze. The salivary ducts from the third postoral segment to the salivary glands (sg) arise in a similar way, and seem to be homologous with trachee. 16. The heart is formed as a solid cylinder of mesoblast in the dorsal region. It afterwards becomes hollow, the central cells perhaps vicariously discharged by the cornicula. 18. The wings arise by evaginations of the dermis, the two plates curving to flatten themselves. 19. The following developmental periods appear to be gener- ally applicable+to insects : (1) Preparatory to organ-budding: as segmentation, gastru- ation, formation of blastoderm, of germ-streak, and of embryonal skin. (2) Organ-budding. (3) Growth of these organs, and appearance of some new ones before hatching. (4) Post-embryonic development of larva; now the gener- ative organs reach full development.—G.

Saupine in con- junction with Dr. Bütschli, but having been left in an incomplete condition, a brief résumé of the more important new facts seemed desirable. | : revious observers have noted the occurrence of conspicuous structures upon the antennz of Chilognatha, which correspond _ to the so-called olfactory cylinders of insects recently studied in -= detail by Hauser, and between the two there seems to be a a general similarity. 1885.] Entomology, 177 Each of the sensory processes is entered by a nerve which immediately divides into two branches, each covered with gan- glionic cells which are distributed in two groups, the anterior one consisting of considerably smaller cells than the posterior ones; at the distal extremity the nerve-fibres again collect into a bundle and form the termination of the organ; that these fibers are differently constituted from those which enter the ganglion rom above is shown by the fact that their behavior to staining reagents is different; the sensory process is often at the free extremity so that a direct communication is established between these nerve-endings and the outer world. A structure essentially similar to this is found in Vespa, but is differently construed by Hauser; according to him the posterior group of cells is not present, since he only figures one nucleus with several nucleoli, however, while the anterior group of smaller cells has escaped his attention; accordingly the conclusion to which Hauser has arrived at is that the whole sensory structure is a single cell; whereas in reality it consists of a great number of cells.—/ourn.

Joyeux- Laffuie, from his own studies and a consideration of what has been discovered by other naturalists, comes to the conclusion that the poison organ of the scorpion (ZL. occitanus) is formed by the sixth or last somite of the post-abdomen, which terminates by a sharp pro- cess, at the extremity and sides of which are two oval orifices by which the poison escapes. * There are two secreting glands, each of which opens by an excretory duct to the exterior.

OCCURRENCE OF TACHINA FLIES IN THE TRACHE OF INSECTS.— N. Cholodkowsky gives in Zool. Anzeiger (June g) an account of a young larval Tachina 1 ™™ long found in the ventral stigma of a carabus beetle. He afterward found the same kind and another species of Carabus infested with fully grown Tachina maggots. He also found a Harpalus ruficornis literally packed with these larvee. The occurrence of Tachina larve in the bodies of grown-up insects is, he adds, no new thing. In 1828 Bohéman found in Harpalus ruficornus and aulicus the larve of Uromyta curvicauda ; Léon Dufour described Hyalomyia dispar as a parasite of Brachyderus lusitanicus ; he also found the larva of Phasia in Pentatoma grisea and Cassida viridis and the larva of Ocyptera bicolor in Pentatoma grisea. Boye in 1838 took Tachinz from three species of Carabus. Within a few years Kinkel d’ Hercu- lais found the maggot of Gymnosoma rotundatum in the body of Pentatoma. Eaton’s MONOGRAPH oF ReEceNr EPHEMERIDE. Part 11.—We have already (p. 630) called attention to this elaborate work. This part concludes the descriptions of the species as well as the nymphs when known. A most important feature of this part is the illustration of the nymphs, which have been drawn with great detail and engraved by A. T. Hollick, filling twenty large plates. Between this magnificent work and the elaborate memoir by Vayssiére, as well as the papers of Joly, the Ephemerids certainly have no reason to complain; though their own lives scarcely span a day, their historians have devoted years of research to them. : STRUCTURE AND FUNCTION OF THE LEGs oF INsEcTs.—We have already called attention to this essay by F. Dahl. The Journal of the Royal Microscopical Society for October contains an abstract of it, which our entomological readers will find of interest. The constancy of the number of six legs is probably to be explained as being in relation to the functions of the leg as climbing organs ; one leg will almost always be perpendicular to the plane when the animal is moving up a vertical surface; and on the other hand we know that three is the smallest number with which stable equilibrium is possible; an insect must therefore have twice this number, and the great numerical superiority of the class may be = associated with this mechanical advantage. This theory is not weakened, but rather supported, by the fact that the anterior pair = of legs is rudimentary in many butterflies, for these are almost exclusively flying animals. 1885.] Entomology. 179 The author describes in some detail the arrangements of the muscles of the legs; the nerve-cord supplying them is pretty stout, and the large number of filaments sent to the joints of the tarsus lead to the supposition that these have a tactile function; the nerve-fibers are seen to enlarge into thick spindle-shaped ganglia. There are two tracheal trunks. The prime function of the leg is locomotor, and insects move through gaseous, fluid and solid media. The last is seen in fossorial forms, of which Gryllotalpa may be taken as the type; here some of the joints are flattened out and provided with teeth, and the muscles are well developed. In some cases, legs of a fossorial type are possessed by insects which move on the ground, but the larve of which are subterra- nean in habitat. The water-beetles and aquatic Rhynchota have the legs converted into swimming organs; they are widened out into plates, and provided at the sides with movable hairs, which are directed slightly backward. The median pair of legs in Corixa is provided with two very long hooks, the function of which is to x the animal at some depth among the water-plants, and so to prevent its floating upwards. In the aérial forms, we have first to notice those that move on the surface of the water; in these the legs are often provided with considerable enlargements of the tracheal trunk, by means of which they are enabled to float. Others have very long legs, by which they can balance themselves and extend over a large surface of the water; the lower surface of the tarsal joints, or that which is in contact with the water, is provided with thick hairs. In some Diptera hairy lobes are developed. Arrangements for climbing are very widely distributed, and are very various in character; the most common are hooks, which by their sharp tips are able to enter the smallest depressions, and so obtain a firm hold; some- times they are pectinate and enabled to catch hold of fine hairs. In very many cases there are organs of fixation; in the locust they have their chief mass made up of a large number of free flexible rods (not tubes). The periphery is occupied by scales which correspond in number to the rods, with which they appear to be connected by fibers; the space between the rods is filled with a fluid. Below these are groups of spindle-shaped cells which appear to be glandular in character. The fixing surface of the Hymenoptera, Neuroptera, and Lepidoptera consists of an impaired lobule placed between the hooks; their structure is most complicated in the first-named order. Observations on Vespa crabro did not result in the detection of any space which could be regarded'as a vacuum. The lower surface of the lobule is soft and almost smooth; a few short hairs may be developed at its base; below this is a hard chitinous mass with stronger hairs. The upper surface is either covered with hairs or is finely folded. Near the base is a chitinous plate carrying a pair of strong sete. -s 180 General Notes.

The legs may, further, have a sexual function as attaching or holding organs; or, as in Mantis religiosa, Nepa cinerea, etc., they may be of use in seizing prey; and, finally they may be used as cleansing organs. The legs in ants may be seen to be pectinate, an admirable arrangement for forms that live in dust and earth; | they are often especially adapted for cleansing the proboscis and for other functions, for an account of which we must refer to the paper itself. Entomo.ocicaL Notes.—Dr. Brauer, says Psyche (Aug., Sept.) has noticed the transformations of a fly (Hirmoneura obscura) whose larva lives on that of the grub pee pupa of the June beetle, Rhizotrogus solstitialis. Mr. O. Lugger, according to Science Record has discovered a strange hymenopterous parasite infest- ing the larva of Tiphia, a black sand-wasp. The Tiphia lays its eggs in the larva of our June beetle (Lachnosterna fusca); the larva of Tiphia when nearly mature eats the white grub and then spins for itself a beautiful silken cocoon. This larva in turn is often infested by the larva of Rhzpiphorus pectinatus or R. limbatus, the eggs of which have become fastened to the Tiphia, and in this way reach the Tiphia cocoon. Mr. Lugger has also found in the same cocoons small hymenopterous parasites. — Interesting cases of lack of symmetry among insects are described in Psyche by O.P. Krancher. Mr. P.

A _ carefully prepared and very just tribute to the memory of our greatest entomologist, Dr. John L. LeConte, by S. H. Scudder, appears in advance from the Transactions of the American Ento- mological iety. We have received a well illustrated report on the tea-mite and the tea-bug of Assam, by J. Wood-Mason, of Calcutta ; the mite puncturing the leaves so that “a badly smitten garden may be recognized from a distance by its red color,” and the bug also blighting the leaves. It appears that of the two spe- cies of tea plant cultivated in Assam the indigenous species which affords the strong and rasping liquor, when pure, enjoys an almost complete immunity from attack, while the milder juices of the imported Chinese bush render it liable to attack. Mr. Mason then asks how the bugs distinguish between different but closely similar plants, infallibly selecting the right food-plants for their larve.

THE DEEP-SEA EXPLORATIONS OF THE “ TALISMAN” (continued). —The Sargasso sea was then visited, and deep-sea soundings made to ascertain the nature of the bed of that part of the ocean. From Cape Verde, the ocean gradually deepens toward the 25th parallel, when it attains a depth of 6267 meters; but it gradually rises toward the Azores, and, under the 35th parallel, it is not over 3175 meters deep. These results are far from being in accord with the indications on the charts of the Atlantic ocean recently published, where the curves of depth give very consid- erable inequalities. Whenever soundings were made, specimens ofa very fine ooze, formed of fine particles of pumice, mixed with globigerina, were brought up. This ooze, at first reddish near the Cape Verde islands, afterward became of an almost pure white. Each time the dredge furrowed the face of the sea-bottom, it was more or less filled with fragments of pumice stonea nd of volcanic rocks. It would seem as if there were, more than a league under the sea, a great chain of volcanoes parallel to the African coast, and of which the Cape Verde islands, the Madeiras, the Canaries and the Azores were the only points of emergence. : The submarine fauna there is scanty. To the stones were attached brachiopods (Discina atlantica). A blind Fusus (Fusus abyssorum), and a new genus of Lamellibranchs (Pygotheca fra- gilis), as well as several Pleurotoma, occurred. Some Crustacea, such as hermit crabs (Pagurus pilimanus), which lodge in colonies of Epizoanthus, and which have already been dredged on the African coast, some amphipods of the genus Nematocarcinus, Holothurians of the group of Elpidia, of which one species was new, Asterians, Ophiurans, and rare corals, scarcely indemnified e party for the time given to dredging at such great depths. It was only toward the north limits of the Sargasso sea, neat the Azores, where the depths are 3000, 2500 and 1400 meters, _ that our collections became abundant. The 11th of August, at 2900 meters, the tog party captured the giant of — Me family of Schizopodes—a Gnathophausia, of a blood-red, T Eoo almost 0.25 millimeters in length, and meriting well the specific name of Goliath, which has been applied to it. In 1885.] Zoblogy. 183 the ‘same dredge with this crustacean was found a fish of the group of Stomias, with lateral phosphorescent plates. Further on, at 1500 meters, several mollusks of unknown species (Scaph- ander, Pleurotoma, and Oocorys), the Dentalium ergasticum, a great variety of Crustacea, Holothurians, Asterians, Ophiurans and other Echinoderms, contrasted with the penury of the preceding days. After visiting Fayal, the Talisman explored the uneven vol- canic bottoms of the passages between the Azore islands, making several successful hauls at the depth of 1250 meters. Some fishes, large red Aristes, Heterocarpus, Galateas of the genus Diptychus, a squid (Cirrhoteuthis) peculiar to Greenland, Actinias, whose edges close together like a bivalve, many star-fishes, speci- mens of Lophohelia, with their usual retinue of Mopsea, soft sea- urchins (Calveria), large and beautifut Holtenias, recalling the redgings some weeks previously off the coast of Morocco. At a little distance from St. Michel, the declivity of the sea- bottom is very rapid. Some hours after our departure, our sounding apparatus already indicated almost 3000 meters, and some of the species found on the plateau situated west of Cape Ghir were brought up. Among others, some large Holothurians, of an amethystine color. On the following day the depth was 4415 meters, and tor four days after it continued to be about the same. 4060 meters the 24th, 4165 the 25th, 4255 the 26th. The very large fishes of the genus Macrurus, which had been brought up during the expedition, also occurred here. They differed fromt hose of lesser depths. The Scopeli and Melanoceti were here also associated. Some hermit crabs and Galatheas of new form; some Crangons, with red eyes; a gigantic Nymphon of the genus Colossendeis; some Ethusas, different from those already known ; some Amphipods and Cirripedes represented the Crustacea. But this abyssal fauna owed its special physiognomy to the large Holothurians of strange forms which abounded; some whose length reached 0.65 millimeters, and whose violet colors were very intense, belonged to a new species of the genus Psy- chropotes, so remarkable from the existence of a very much developed appendage, ending behind the body, and resembling a queue; others, of the genus Oneirophanta, were easily recog- ; nized by their pure white color and long appendages, which garnished the whole body. Others of a delicate rose, carried on the back an erectile, fan-like membrane; these new Pentagonias were like those found by the Challenger at the greatest depths ex- plored. Finally, large Actinians, some of which lived as parasites on the Holothurians, some Hymenasters, Asterians, a Brisinga with few arms, some Ophiurans and a crinoid, were found in the same situations. Aug. 27th, the sounding apparatus reached a depth of over 184 General Notes. [February, 5000 meters, and a new species of Neæra, and different Crustacea occurred with others previously dredged. ore than fifty rosy Pentagonias were dredged, mixed with a less number of Oneiro- phanta, Archaster and Ophiomusium, attested the richness of this deep sea fauna. The bottom of the sea throughout this region is carpeted with a white ooze formed almost entirely of globigerines. Pumice and volcanic stones are mixed with it; but that which surprised us most was to find some pebbles polished and striated with ice ata distance of more than 700 miles from the coast of Europe. The distinctness of the striations could not allow us to admit that these pebbles had been transported by currents, because they would never have rolled, and, besides, they lay at such a great depth, that the tranquillity of the water there should be very great, to judge by the nature of the ooze deposited there. Their presence is probably due to transportation by floating ice, which, during the quaternary epoch, advanced further south than in our day, and which, melting in the part of the Atlantic ocean lying between the Azores and France, let the stones fall on the bottom with the fragments of rocks torn from the bed of the glaciers, and which they had transported there. Aug. 30th, dredging at the depth of 1480 meters in the Gulf of Gascony, revealed polyps of the genus Lophohelia, with splendid Pentacrini (P. ay & Petre gigantic Mopseas, Gor- gonias, and corals, etc.—A. S. Pac Tue Nervous System OF ANTEDON.—Various opinions have _been held in regard to the nervous system of the crinoids which has been held by some to consist of the bands along the bottom of each ambulacral groove corresponding to the nerve cords of the | star-fish, while others have maintained the nervous nature of the axial cord and its connections. Dr. Carpenter first suggested the | Othe the nature of this cord in 1865, and in 1874 further developed the theory that the axial cords are nerve-trunks, and the five- _ chambered organ in the centrodorsal basin is their center, and as proof adduced the fact that an eviscerated specimen suddenly and consentaneously closed its ten arms when a needle was thrust into the chambered organ. P. H. Carpenter, in 1876, was the first to maintain the nervous character both of the sub-epithelial bands of the ambulacra and of the axial cord. Recent experi- ments, carried on by Dr. A. M. Marshall, have established con- clusively that the central capsule and axial cords, with their Branches, constitute, as maintained by the Carpenters and Perrier, i main nervous system, while the sub-epithelial bands are also bably nervous, but have only a special and subordinate func- : Baas in connection with the ambulacral tentacles and epithelium. — The complex co-ordinated movements of swimming and righting - when inverted, are all executed by the axial system, as was £ 1885.| Zoology. 185 proved by the fact that eviscerated specimens in which the con- nection of the sub-epithelial bands with each other was destroyed, were capable of executing these movements. The axial cords act both as afferent and efferent nerves. LEvisceration causes apparently but little inconvenience to the animal, and the visceral mass is regenerated completely in a few weeks. The apparent morphological difference between the nerve system of the Crin- oidea and of other echinoderms disappears upon examination. Taking the Asterids as the lowest term of the series, it will be found that in those creatures, as shown by Hamann, nerve fibrils are found over the entire dorsal surface of the animal. While in Ophiurids, Echinids and Holothurids the ambulacral portion of the continuous nervous sheath of the star-fish has concentrated into a well-defined cord, the remainder being absent; in the crinoids the ant-ambulacral or dorsal part being continuous nerve-sheath of the star-fish has developed into the so-called axial cords, and the ambulacral bands also subsist as a subordi- nate nerve-system. HERRICK’S CLADOCERA AND COPEPODA OF MinneEsoTa.’—In this excellent report we have for the first time a summary of the known genera and species of all our fresh-water, free-swimming Entomostraca with the exception of the Ostracodes. It will prove not only useful but stimulating to our inland naturalists. As a pioneer work it is entitled to much credit, since many of our species are identical with those of Europe, and much care is required in the generic and specific descriptions, since the distinc- tions are based on such slight characters. In the introduction the author shows how important these micro-crustaceans are as scavengers, and in what astonishing numbers they exist, 1442 specimens occurring in a quart of filthy pond water. The discussion of the affinities and genealogy of the Clado- cera is interesting ; this is’st led by an account of the lead- ing works on them. The order, families and genera are charac- terized with sufficient fullness, and a tabular view of the classifi- cation of the Cladocera is given, as well as useful keys to species under each genus. Under the family Daphnide a long account of the circulatory system is given from original observations, The Copepoda are treated in the same manner as the other order, and all the species collected by Mr. Herrick or previously known are described, but why no description of Canthocamptus tenuicau- dis, n. sp., is given, we hardly understand, though it is figured, while C. cavernarum Pack., from Mammoth cave, is not men- tioned.

The work will do credit to the author and be of service in directing attention to these creatures, and it is to be hoped that the author will be able to add to and extend the work, and ina few years give us an enlarged and improved edition of it,as a hand-book of our fresh-water Entomostraca would be useful. The plates should have been numbered not lettered ; Limnetis is spelt Limnetes, but the typographical errors are not numerous, MORPHOLOGY OF THE VERTEBRATE AUDITORY OrGAN.—The chief vertebrate sense organs have certainly had a very different origin. The olfactory organ is probably a modified gill olfactory and auditory nerves as well as the eye. But recent researches, especially those of Marshall and Van Wijhe, have proved that the auditory nerve is merely a dorsal sensory branch of the 7th cranial nerve (3d segmental nerve of Van Wijhe). It has been shown above that the nerves which supply the segmental sense organs are dorsal sensory branches of the seg- mental nerves, that the segmental sense organs are merely modi- fied portions of the epiblast, that these sense organs primitively, and in some existing form still throughout life, lie free on the surface of the body, but that later in most cases they become shut off from the epidermis in a sac which remains connected with the external world by a small opening. The sensory cells of these organs possess long fine terminal hairs, which are easily affected by wave-motions in the medium in which the animal lives, and which communicate this wave motion to the nerves connecting them with the brain. Do we really meet with this condition of things in the auditory organ? In other words, is the auditory organ merely a specially modified portion of the system of segmental sense organs ? The auditory organ is, like the segmental sense organs, really a modified portion of the epiblast. Very early in development it becomes shut off in a sac from the epidermis, a condition which only arises later in the segmental sense organs. Phe semicircular canals, etc., are clearly secondary compli- cations, for in every embryo the auditory organ is at first a simple sac shut off from the epidermis, of which sac a portion of the inner wall consists of two layers of modified epiblastic cells, connected by a dorsal sensory branch of a segmental nerve with the brain. © This double layer of modified epiblastic cells is in every way — . ON 1885.] Zoblogy. 187 comparable to a segmental sense organ. As in the latter the cells on the free surface possess long hairs. These hairs like those of the segmental sense organs are concerned with the per- ception of wave-motions of the medium in which the animal lives. The hairs on the auditory cells are indeed concerned with the perception of much finer wave-motions—those of sound—than those on the cells of the segmental sense organs, and hence arises the early shutting off of this organ from the skin. The inner layer of cells of the auditory organ is exactly comparable to the inner layer of cells of a segmental sense organ In Teleostei, etc., the auditory organ beedmes entirely shut off from the skin, ut in Elasmobranchii the aperture of invagina- tion persists, and the organ is —— ma the surface through- out life, just as the segmental sense or ese facts, together with the fact that the auditory nerve is merely a dorsal sensory branch of a segmental nerve, seem to point to the conclusion that the auditory organ of vertebrates is fundamentally a specialized portion of the system of sense organs of the lateral line, specialized above the rest of the system by the acquirement of the more delicate function of the perception of waves of sound. In accordance with, and as a direct consequence of this func- tion of receiving waves of sound, the auditory organ has been early shut off from the external surface, and has developed ac- cessory structures in the shape of semicircular canals, etc. Thus its primitive simplicity has been lost. I hope shortly to give elsewhere a more detailed statement of the points touched upon in this paper.—Fokn Beard in Zoölog-' ischer Anzeiger, 1884. SOME PRELIMINARY NOTES ON THE ANATOMY OF FISHES.— . On the cutaneous Sense-organs.—Since the distinetion between endknospen on the one hand, and nervenhiigel, nervenletsten, ner- ae on the other, is generally recognized, it becomes desi-. their shape, the term neuromast with the adjectival form neuro- mastic. At the meeting of the British Association in Montreal, in Sep- tember, I pointed out that the catfish possesses neuromasts in sacs, recalling those of the sturgeon. They resemble these, in ct, more closely than do the similar structures of Amia an Lepidosteus, which I have recently studied. The neuromasts belonging to a group are connected by a canal lodged in the corium, which is lined and in places filled by an epithelium, con- tinuous with the epithelium of the .neuromasts. Such a canal 188 General Notes. [February, has recently been described by Carriére for Cobitis, although he has not recognized its true character. The deep neuromasts found by the same author in Tinca are evidently somewhat simi- lar to those ot the catfish, and it is probable that connecting epi- thelial canals will yet be found. The only explanation of these canals which has so far occurred to me is, that they are the remains of a more complicated system of cutaneous canals simi- lar to those of the Selachii. In striking contrast to such deep neuromasts are those lodged on the projecting papilla of the blind fishes. Professor S. A. Forbes has described the distribution of these in his Chologaster papilliferus, a specimen of which he has kindly given me for exami- nation. I find that whereas the trunk in this species has only the free neuromasts, the head has neuromastic canals arranged in the ordinary way, and corresponding roughly in their course to the chief tracts of the projecting papilla. A singular circumstance is, that they have only four openings on each side, one posterior above the gill-aperture and three anterior on the snout, the pores of the mandibular, infraorbital and supraorbital canals respect- ively. I take the opportunity of mentioning here that the absence of pigment in the pigmentary epithelium of the retina of this species as very significant. 2. On the fate of the spiracular cleft in Amia and Lepidosteus.— It is generally supposed that the spiracles of the sturgeon are unrepresented in Amia and Lepidosteus, but a minute slit may be seen in both genera on either side of the roof of the mouth, immediately in front of the dorsal ends of the first branchial arches, leading into diverticula of the mouth-cavity—the rudi- mentary spiracles. If a bristle be pushed into one of these slits, it will be found to pass through a canal in the primordial cranium ~ _immediately*abeve the anterior end of the hyomandibular articu- ation, and to be only prevented from emerging on the roof of the ‘skull by the squamosal bone. Sagemehl has seen the canal in mia without attributing to it any morphological significance. In series of sections through young specimens of both genera, I find a free neuromast projecting from the epithelium of the ante- rior wall of the distal part of the cleft, supplied by a distinct _™ division of that dorsal branch of the ¢rigemunus (the ramus oticus = of Van Wijhe), which is distributed to the neuromastic canal in the squamosal bone. I conclude that the distal part of the cleft is epiblastic in origin, although Balfour believed (as far as Lepi- dosteus is concerned) that it never acquires an opening to the exterior. Ina recess of the anterior wall of the spiracle in Amia is situated a pseudobranchia. This has recently been styled an “opercular pseudobranchia,” in accordance with Gegenbaur’s = views as to the homology of the pseudobranchia of the Teleosts, _ but the discovery of its relations to the spiracular cleft demon- a a | i eee ee a eS 1885.] Zoology. 189 strate its homology with the pseudobranchia of the sturgeon. As there can be no doubt of the homology of the pseudobranchia of Amia with that of the Teleosts, it follows that it is the “ opercu- _ lar” gill and not the spiracular gill which disappears in the Tele- osts. Dohrn has recently defended this from another stand- point. Johannes Mueller’ sview is in opposition to that of Gegen- baur ur. The pseudobranchia appears to be represented in Lepidosteus by a mere anastomosis. That genus, has, however, an “ opercu- lar” gill (absent in Amia), the two parts of which, although differ- ing in their vascular supply, correspond to the complete opercu- lar gill of the sturgeon. Balfour was unable to find this gill in young specimens of an inch in length. I have arrived at the above result from the study of specimens of two inches. 3. On the auditory organ of Hypophtha/mus.—In a recent paper I described the connection between the air-bladder and auditory organ in the catfish (Amiurus), paying special attention to the morphology of the’ modified anterior vertebrz which establish this connection. Reissner had previously pointed out that in many tropical Silu- roids this “ Weberian apparatus ” is much reduced, but his identi- fication of the altered vertebre is so out of harmony with my results that I was glad to be able to re-investigate the matter through the liberality of Professor B. G. Wilder, who put at my disposal last spring a number of the forms in question as well as others. As was to be expected, the four anterior vertebrz are always modified in a similar manner throughout the group. „The genus Hypophthalmus, according to Günther, presents an exception to the other Siluroids, in that the anterior vertebrz are not united, but as a fact this genus exhibits an extreme type of reduction of the Weberian apparatus. The four anterior verte- bre are not only united, but the first three of them are tele- scoped, as it were, into the occipital region of the skull, so that a frontal section through the plane of emergence of the third pair of nerves, falls also through the saccu/i of the auditory laby- rinth. The air-bladder is represented by two entirely separate bladders, about 2™™ in length by 3™™ in width, almost entirely enclosed in osseous capsules, situated on either side of the fourth vertebra, and coalesced with it. These osseous capsules repre- sent the crescentic ossifications in the external tunic of the air- bladder of the catfish which are attached to the posterior ends of the “ mallei” All the Weberian ossicles are represented, but the whole apparatus is so reduced as to be obviously quite func- tionless. In conformity with this the /agenar parts of the audi- tory labyrinths are much smaller than in the catfish, while the saccult of opposite sides still communicate by a transverse duct. In compensation, as I think, for the reduction of the Weberian apparatus, the neuromastic canals of the head and trunk are 190. General Notes. [ February, enormously developed,*and the dorsal branches of the various cranial nerves which supply these, and which center in the ¢ader- culum acusticum of the brain, are correspondingly large. This appears to me an additional confirmation of the theory advanced by Schultze and Mayser, that the cutaneous sense-organs of this class constitute a form of auditory organ.—R. Ramsay Wright, University College, Toronto, Dec. 18, 1884. : P. S.—After writing the above, I learn from Professor Wilder that he indicated the existence of rudimentary spiracles in Amia and Lepidosteus at the A. A. A. S. in 1878. His MS., which remains unpublished, discusses the nature of the spiracles and their persistence in a more or less complete form in Selachians, Ganoids and the Teleost Megalops, describes the form and rela- tions of the spircular clefts in the adult Amia, and concludes that these are open in the young. The relation of the pseudobranchia referred to above is not in- dicated. —R. &. W. THE Larva OF EsTHERIA MEXICANA.—(The following descrip- tions and figures were received from the late Mr. V. T.

[February, ABERRATION IN THE PERCH.—I wish to note a peculiar ana- tomomical aberration in a common perch (Perca americana) which has just come under my observation. In examining some of these fishes from Lake Michigan, an assistant noticed that one of them had no pyloric cceca. The viscera were placed in alco- hol with others, and on opening the alimentary canal for the pur- pose of removing its contents, I noticed a fleshy mass apparently nearly occluding the pyloric opening, the pyloric portion of the stomach being stretched somewhat tightly over it. Finding that this was not detachable I took it for a tumor, but a closer examina- tion showed that it was divided into three finger-like lobes, of the shape and size of pyloric tubes, and that each of these lobes was hollow, opening upon the outer surface of the intestine by an ori- fice large enough to admit a knitting-needle. Evidently these were the missing pyloric coeca, which had grown wrong side out ; for I cannot conceive of any accident which should turn these structures within the body of. the fish. The exposed surface is a mucous surface, and that within the cavity of the pyloric tube is a serous surface, like that of the out- side of the intestine.—S. A, Forbes. - A LIZARD RUNNING WITH ITS FORE FEET OFF THE Grounp.— In the proceedings of the Linnean Society of New South Wales, 1884, it is stated that Mr, Macleay exhibited a lizard which was observed to run for six yards in an erect posture with. the fore legs quite off the ground. The lizard was of the genus Gramma- tophorus, of which there are several species in the country, all of them much given to playing and gambolling on sunny days. FEATHERS OF THE Dopo.—The feathers of the dodo have been studied by Professor Moseley,who read a paper on the subject at the Montreal meeting of the British Association. He showed birds of the dove family, near which the dodo is placed. Earlier in the development of the dove’s feathers the filoplume are larger, relative to the size of the other feathers; and this condi- tion resembles still more the structure found in the dodo. THE _ARMADILLO IN TExas.—G. H. Ragsdale, of Gainesville, Texas, informs me that an armadillo was recently killed in northern Denton county, Texas, which is the only animal of the kind ever taken in that part of the country. The armadillo is said to have been common on the Rio Grande river twenty years ago, and is still;common in the south-western counties of Texas.—A. Hall (E. Rockfort, Ohio), in Forest and Stream.

An instance somewhat similar to the one mentioned came under my own notice in the early part of July, 1877, whilst camping within a few miles of the village of Kempville, some thirty-two miles south of Ottawa. In company with Mr. P. B. Taylor, of the post-office department, I was row- ing up “the Branch,” a small tributary of the Rideau, when we noticed a large woodchuck come down the bank and take boldly to the water, with the evident intention of crossing to the other side. The stream was at this point about 30 or 40 yards wide, and we pulled hard in order to come up with the animal before he could reach the opposite shore. As soon, however, as the woodchuck saw us he appeared to take in the situation, and made vigorous efforts to escape; and as he could change his direction much more quickly than we could, he succeeded for some time in eluding us. But we finally managed to get within reach of him and I lifted him into the boat by the back of the neck. He shivered a good deal and looked intensely uncomfortable; but his long swim did not appear to have tired him much, for he struggled violently to free himself, and when subsequently re- leased he leaped over the side of the boat and swam back to the shore from which he had come. He swam low in the water, pro- gressing but slowly and with evident exertion—W. L. Scott, Ottawa, Canada. Nest oF NEOTOMA FLORIDANA (identified by Dr. Coues, with question)—While hunting, the other day, my attention was called to a singular nest of some animal, made on the ground, just in the edge of a clump of mesquite brush. It was in the form of a pyramid or rather oval, about two feet and a half high, and four feet in diameter at the base, constructed of cow chips, stones, sticks, lumps of dirt, and every imaginable light substance that could be collected in the vicinity. There were two holes for entrance in the nest, on opposite sides, about the size of one’s coat sleeve. A large thick cactus leaf near one of the orifices had been partly eaten recently. As far as we could ascertain, without destroying the nest, it was unoccupied at the time of our visit. My companion, the signal observer here, is very familiar about here, but this is the only nest of the kind he has seen. A gentleman, who has lived on the Rio Grande, says he has seen them. Can any one tell us what animal lives in this curious nest ?— Fon D. Parker, Fort McKavett, Texas. HAACKE’S Discovery OF THE EGGS OF- THE AUSTRALIAN Ecuipna.—It appears that on Aug. 25, a few days before the announcement (Aug. 29) by telegraph from Australia, of Cald- well’s discovery that a monotreme laid eggs, the telegram not YOL XIX,—NO, II, 13 194 General Notes. [ February, stating whether it was the Ornithorhynchus or Echidna, Dr. J. W. Haacke discovered that Echidna laid eggs. His discovery was reported in the same number of the South Australian Regis- ter as contained Caldwell’s dispatch to the British Association at Montreal. On Sept. 2d, at a meeting of the Royal Society of South Australia, the Register reports: “ Dr. Haacke laid a num- ber of specimens on the table, including an egg found in the pouch of a female Echidna, in support of the theory that the Echidna, although a milk-giving animal, lays eggs which are hatched in the pouch.” Dr. Haacke, in a communication to the Zoologischer Anzeiger of Dec. 1, adds: “I found the egg on the 25th of August last in the mammary pouch (not the uterus) of a living Echidna hystrix, received about the 3d of the same month from Kangaroo island. e egg was unfortunately decomposed inside, but the circumstance of the mother having been worrie by being captured and kept in captivity easily accounts for this.” He also says that in dissecting the Echidna he felt a small object in the pouch ; in hopes of finding a young Echidna he brought it to the light, and was astonished to behold a veritable egg be- tween his fingers! It was from one and a-half to two centi- meters in diameter, and possessed, as many reptilian eggs, a per- gamentaceous shell which, under the pressure of his fingers, burst, letting out thick fluid contents. The scientific public will now look with interest to Mr. Caldwell’s account of his dis- covery. DISTRIBUTION OF Mammats.—At the Montreal meeting of the British Association Dr. G: Dobson read a paper on the distribu- tion of mammals, in which he pointed out the remarkable resem- blance between certain bats of the Australian and Ethiopian re- gions. From this it was apparent that some communication once existed between those continents. There probably had been a chain of islands between Australasia and Africa, which had ex- isted for a short period, by which route the bat had passed from one place to another. Bats were widely spread in Madagascar, Mauritius, and Australia, but there is only one species in India which shows a strong resemblance to the Madagascar bats. So it is evident that at no distant day they had common ancestors. It was, therefore, deduced that there must have been a chain of Australia, Madagascar, and India. Professor Moseley said that the Indian ocean had never been examined as to depth, the _ Challenger expedition not touching it. Dr. John Ball urged that the existence of islands and continents was often too dogmatically laid down; he believed that currents could carry trees which might bear animals and plants with them. : IS See Oey ee en ih en SEDER eA ict geo EAS rien et Bate 5 TE ANES REES, 1885.] Zoblogy. 195 ON THE CENTRALE CARPI OF THE MAmMALS.—Professor H. Leboucq, in his “ Recherches sur la morphologie du carpe chez les mammifères,” Arch. de Biol. Tom. v, 1884, pp. 35—102, pl. 111—-vI, as made extended communications on this subject. I will add some observations, which will complete Leboucq’s results. In this present communication I will speak of the centrale only, and will defer other points discussed by Leboucq to a future ex- tended paper on the morphogeny of the carpus and tarsus of the vertebrates. I have found, like Leboucq and others, a distinct central bone in man, dog and cat. I regret not having been able to examine embryos of bats and marsupials. I can distinguish a centrale in two other specimens of Carnivores, in an embryo of Lutra of 50" and in an embryo of Mustela vulgaris of about 25™™ In Lutra the central bone was quite free and very fully developed, the radiale and intermedium were coalesced. In medium, at that part contiguous to the radiale. In Lutra the radiale and intermedium were entirely coalesced, in Mustela I found traces of a former separation. ~ In an embryo of Erinaceus europeus of 65™™ I found no sign of a free centrale and no indication of a confluence of the bone with the radiale. The first tarsal row consisted of two pieces of cartilage, a radiale and intermedium, and an ulnare. In an adult Erizaceus collaris I observed the same condition as in the embryo. As in the different families of Insectivores, even in the adult state, a free centrale may be found or not, I do not hesitate to believe, that in all Insectivores in which a centrale has not yet n seen, such a bone will be discovered in embryos at some early stage of their development, In regard to the Marsupials I have had ‘no opportunity to ex- amine the embryo." In the manus of the following adult Mar- supials I can distinguish an os centrale coalesced with the radiale, as Leboucq has stated, viz: Didelphys azare, Perameles lagotis and Dasypus maculatus. Further I can state the same for Orni- thorhynchus and Myrmecophaga tetradactyla. A centrale carpi is therefore now shown to occur in all orders of mammals except the Ungulata and the Cetacea. Hyrax capensis possesses, as is well known, a free central bone. Professor Cope places the Hyracoidea together with the Con- dylarthra inthe order Taxeopoda, and considers these the oldest ungulates. If there is a free centrale in one of the oldest ungu- lates, Hyrax capensis, such a bone should exist in the allied forms of this and in the descendants of the Taxeopoda, and I have no hesi- l Since writing the above, I have distinguished in an embryo of Didelphys, nks fessor H.

[February, tation in believing that such a bone will be found in the Amblypoda’ and in embryos of Elephas, Tapir, Rhinoceros and Hippopotamus. Whether itis coalesced with the radiale or with the trapezoid (tars.”) or whether it has become wholly atrophied, I am not able to de- cide. (According to Flower: Osteol. of Mamm., 11 edit., p. 265, in Hyrax dorsalis the central bone is coalesced with the trapezoid.) It would be interesting to know whether in the Periptychide, the Phenacodontidz and the Meniscotheride, the three families of Cope’s Condylarthra, indications of a central bone can be found. It seems improbable that such indications must exist. Further- more in regard to the Cetacea. If Leboucq’s hypothesis, that we might consider in these animals certain ‘‘ metacarpiens”’ as “ carpo-metacarpiens”’ should be shown to be correct, then this last point would be elucidated. Further morphogenetic researches on the limb-skeleton of the vertebrates will remove many present uncertainties and errors. I would hence be glad to receive, from those interested in the subject, any embryological material that will enable me to make further investigations upon these points. The most important stages are, when cartilage begins to appear, or is already devel- oped. In future studies I hope, so far as possible, to elucidate the morphology of the limb-skeleton of vertebrates and to bring to light new points on the phylogenetic relations of the different groups of vertebrates—Dr. G. Baur, Yale College Museum, New Haven, Conn., Oct. 1884. THE TRAPEZIUM OF THE CAMELID&.—Professor Cope? says in regard to the carpus of Poébrotherium, one of the ancestors of the Camelide: “The carpus consists of eight bones, the entire mammalian number, all entirely distinct. The second series pre- sents the most important peculiarities. The trapezium is small and posterior; the trapezoides has an almost entirely lateral pre- sentation, and is also small, and fits an angle of the magnum. There are two principal and two rudimental metacarpals. The second and fifth are very short and wedge-shaped, and closely ad- herent in shallow fossz of the third and fifth, respectively.” It is generally considered that the living Camelide have no trapezium. I cannot, however, agree with this assumption. At the posterior part of the trapezoid of an adult Camelus bactrianus L., I finda well developed articular surface; it is the same face that is seen in different Cervidæ, and can only be for the trape- zium. 1 Professor Cope believes that there is an os centrale (“intermedium ”) in Cory- phodon. - ?

In regard to this lat- ter, Cope says, p. 262: “ Thus the lateral rudimental metacarpals of Poëbrotherium have disappeared, and with them the trapezoides of the carpus.” (This is evidently a typographical error; instead of trapezoides it should read trapezium.) Now if there is a trapezium in one of the living Camelidæ, as I have found, there ought to be one in the older form—Procame- lus. That this is in fact so, seems apparent from the figure given by Cope? of Procamelus occidentalis (P\. LXXIX, fig. 3a). There appears to be an articular surface, at the back part of the trape- zoid and it would be interesting to prove it definitively. The presence of a trapezium in the Camelidz shows that they, like the Cervidz, are ancestral forms of the ruminants. I will discuss this in another place. I do not doubt that we will find in the carpus of camel embryos the same condition as in Poébrotherium. It would be interesting to examine embryos with this view.—Dr. G. Baur, Vale College Museum, New Haven, Conn., Nov., 1884. LAST APPEARANCE OF THE BISON IN WEsT VIRGINIA.—The fol- lowing letter we owe to the kindness of Professor J. Packard of the Theological Seminary of Virginia. The ‘facts regarding the, last date of the appearance of the buffalo in West Virginia will be interesting in connection with the statements in J. A. Allen’s work on the American bison, living and extinct. PRINCETON, MERCER COUNTY, W. VA., April 26, 1877. * Your letter was received several days ago, and would have been answered before this, but was delayed by me with the hope of arriving at such information as some of the oldest of our citizens might be in possession of, which I expected to obtain at our last week’s court. I have failed to get but little beyond the slight traditions I had before; to sum it all up, I think the last buffalo killed on Guyan river was killed by a man named Mor- gan, on a creek’and at a lick called Buffalo, about four miles from its mouth that empties into said Guyan, and about fourteen miles from Logan C. H., and in the County of Logan, in the year 1804. Another one was killed, and perhaps the last one heard of, by Jo- seph Workman on the Deer Skin fork of Coal river, about the year 1810. This information I got from old Stephen Blankenship, who is now in his eighty-sixth year. I learn that old Mr. Work- man is still living, and is ninety-five years old; the buffalo was killed in the present County of Boon, where he now lives. My impression was, before the receipt of your letter, that the last one i Cope, E. D. The Phylogeny of the Camelidz, Proc. Ac. Nat. Sci. Phil., 1875, p. 2 i Report Expl. Surv. W. of tooth Mer. U. S.

A few elks lingered longer, perhaps as late as 1820. I think you might obtain, perhaps, the most accurate information in reach from Col. Benj. H. Smith (P. O. Charleston, Kanawha county, W. Va.), who is an intelligent old gentleman, and has practiced law in all the counties where the buffalo was seen last, he, I think, would likely remember the hunters’ account of his departure from the State. N. B. FRENCH. Anteus and Titanus Perrier, inhabit South America. The genus Acanthodrilus, from Western Africa, has two species which attain a length of three feet. An earthworm two to three feet long oc- curs in the interior of New Zealand, and a similar one in South Australia. But the largest known species is from South Africa. Forty years ago Rapp figured an earthworm six feet two inches long, obtained near Port Elizabeth, and recently Mr. Beddard procured a living example of the same species between four and five feet long and half an inch thick, from the same locality. It expands and contracts within wide limits, and may even be longer ' when fully expanded. Externally it resembles Lumbricus, in having four series of pairs of bristles on each segment, but its internal structure is quite distinct. This worm seems to be abun- dant, but is rarely seen, as it is only driven from its underground. burrows by heavy and prolonged rains; on such occasions, which only occur a few times a year, the ground is covered by hundreds _ of these creatures, slowly crawling around until killed by the sun. A curious fact in connection with these worms is that the hard _ clayey soil in which they reside contains brackish water, thus proving that the presence of salt does not necessarily kill earth- worms and their eggs, as has been supposed. The genus Ponto- drilus Perrier lives among decaying seaweed cast up by the sea. Earthworms would appear to be exceedingly abundant in some parts of New Zealand, if we may judge from Mr. Urquhart’s paper, in the transactions of the New Zealand Institute. The writer calculates that there are in one acre of pasture land near Auckland, 348,480 worms, with a weight of 612 pounds 9 oz. _ Crustaceans.—In describing the head of Palinurus lalandii, Pro- fessor T.

All the species of Jasus (omitting P. longimanus and P. frontalis, of which no definite information could be obtained), are confined to the southern hemisphere, those of Palinurus to > the northern, while those of Panulirus occur in both. _ . Fishes—Mr. R. M. Johnston, in the Proc. Roy. Soc. of Tas- mania, enumerates 188 known species of Tasmanian fishes. Of these about one-third are good edible fish, though only twenty- one are sufficiently abundant to be of importance. ates colon- orum, a well-known species in Australia, seems, in Tasmania, to be confined to one small river on the north-east of the island. Mammals—Mr. G. E. Dobson states that many of the most characteristic species of Australian Chiroptera have their nearest allies in the Ethiopian region. Thus Chalinolobus and the sub- genus Mormopterus are South African and Australian. Mega- derma gigas, of Queensland, has its nearest ally in JZ cor from Eastern Africa, and Trizenops, a remarkable leaf-nosed bat found in Madagascar, Eastern Africa, and Persia, has its nearest ally in the Riinonycteris aurantia of Australia. Finally, Australia agrees much more closely with Madagascar, and the Mascarenes than with the oriental region, in the species of Pteropus, eighty per cent ` of which inhabit the Australian region and Madagascar, with its islands. r. G. E. Dobson (Proc. Zool. Soc., April, 1884) de- scribes the myology and visceral anatomy of Capromys melanurus. The specimens on which the description is based were from the mountains of the southern end of Cuba, and appear to be the first of which the complete bodies preserved in spirit have reached Europe. The four known species of Capromys, pilorides, brachy- urus, prehensilis and melanurus are confined, so far as known, to the islands of Cuba and Jamaica, where they are the only indig- enous rodents. C. drachyurus is limited to Jamaica, the others to Cuba. The liver of this species differs remarkably from that of C. pilorides, in the absence of that sub-division of the hepatic lobes, which has been described in the latter species, and has been thought a generic character. M. Testut (Bull. de la Soc. Zool. de France, vil, 1883) has observed in twenty subjects the fusion of the flexor muscle of the thumb with the general flexor of the digits. As the presence of a separate muscle for the flexure of the thumb, causing that digit to be perfectly independent in its movements, is one of the characters made much of by those who wish to find a broad difference between man and the apes, it is significant to find this character so often absent. In three cases the two flexors were completely united into a single muscle. To meet with this. character it is necessary to go back to the Cercopitheci, for in the anthropoid apes the muscles have a greater or less tendency to separation. In the gorilla, the flexor muscle divides into two parts, one of which goes to the thumb and first finger, the other to the re- 200 General Notes. [February, maining three fingers. This anomaly was found by M. Testut on both arms of one subject. In the orang, not only are the two deep flexors united, but there is no tendon for the thumb, and this abnormality has been observed in man by Gruber, Wagstaffe, Gegenbaur, and Chudzinski. M.Testut believes that he can trace the presternal muscle, which in three or four per cent of the human subjects that have been dissected is present, and is con- nected above with the sterno-mastoid tendon and below to the great oblique, to the condition of things which obtains in ser- pents (or rather in vertebrates deprived of a sternum) in which the great oblique is attached to the mastoid apophysis. The sterno-mastoid and great oblique muscles are identical in their position with regard to the tegument, their direction, and their in- sertion on the haemal axial line, but where a sternum is present, the muscular fibers which descend from the mastoid apophysis find insertions upon it and upon the clavicle, and the part inter- vening between these insertions and what is now the great oblique becomes atrophied. Muscular anomalies are frequent in man, but M. Testut, in an important work upon this subject, shows that the muscles subject to these anomalies, which dis- appear entirely in some, while in others they are abnormally developed, are muscles which play an unimportant part in the human economy, and are links which unite man to the lower animals. EMBRYOLOGY.' THE DEVELOPMENT OF THE Rays OF osseous FisHes.2—Since the time when Vogt published his work on the development of the salmonoids, in 1842, it has been known that the earliest traces of rays to be noticed in the fin-folds of young fishes were fine, very numerous filaments, lying parallel to each other. Th. Lotz, in 1864, carried Vogt’s observations farther, and thought he showed that by the coalescence of these filaments the rudiments of the permanent rays were laid down. Both A. Agassiz and myself have found these filaments in the embryo of numerous widely separated genera of teleosts; the former having also pointed out their existence in Lepidosteus. They also exist per- manently in an almost unmodified form in the Dipnoans, as shown by the researches of Giinther and others, Balfour and myself have found these filaments in all of the fin-folds of Elas- mobranchs, though they seem to be wanting in the more fleshy pectoral of some of the Rays, They are present in the fin-folds of embryo sturgeons, and there probably give rise to the permanent 1 Edited by JoHN A.

In all the forms so far made the subjects of observation, these embryonic filaments are much more numerous than the perma- nent rays, and appear clearly defined in sections between the mesoblast and epiblast which constitute the fin-folds when the rays are being formed, these filaments then become covered ex- ternally by a more or less clearly defined layer of mesoblast about one cell deep, or, if they are not forced inwards in this way, they coalesce directly to form the basement membrane of the permanent rays. Usually, however, they are forced inward by the radial proliferation of the mesoblast spoken of above, and they then degenerate, their substance being. apparently carried out to the surface of the mesoblastic core of the permanent rays by a process of metabolism to form the basement membrane of the latter which is crescentic in sections, and immediately over- laid externally by the integument. As this new formation takes place proximally it would appear that the primitive radial fila- ments had coalesced by their parallel sides distally, and fused into a continuous semi-tubular strip of basement membrane which maintains its more primitive fibrillated form distally or at the margin of the fin, thus giving rise to the dichotomous structure of the right and left halves of which a caudal fin-ray is almost always composed in osseous fishes. The primitive radial fibers (=embryonic fin-rays of A. Agassiz) appear first at about the end of the lophocercal stage around the end of the tail and in the pectorals. In Gadus embryos, three weeks old, the first traces of these filaments appear at the end of the tail, in the vertical fold surrounding its extremity, as numer- ous elongated cells with fine protoplasmic prolongations extend- ing in one direction toward the axis of the body and in the other away from it. These spindle cells are arranged like the filament- ous rays which develop later, that is, their processes extend nearly parallel to the processes of those adjacent. These rudi- ments of the embryonic filaments bear a remarkable resemblance to cells found imbedded in the rays of Ceratodus, as figured by Günther in his memoir on that form. I will therefore call them plerygoblasts ; their origin is mesoblastic and not epiblastic. They develop into the embryonic radial filaments, but the extent to which these are differentiated in the median fins of Teleosts is very variable. Amongst those forms which have continuous median fin-folds developed as well as a pre-anal fin-fold, Salmo is the only form known to me which has them developed through- 202 General Notes. | February, out the entire extent of those folds; Alosa, also a physostomous form, does not have them developed nearly so extensively at a corresponding period. In forms with discontinuous folds, as Siphostoma, for example, they are not very evident even at the time when the caudal rays are being formed, but aside from such exceptional forms they seem to be almost universally developed to some extent in the fin-folds of all truly fish-like forms except the lampreys and the lancelet. In consequence of the striking resemblance which this stage of the development of the rays of the most specialized fishes bears to what has remained nearly permanent, with but comparatively little modification in the Chimzroids, Elasmobranchs, Ceratodus and Protopterus, I propose to call this the protoprerygian stage of the development of the fin rays in the Teleostei. The primitive fibers in section are shown to be perfectly cylindrical and homo- geneous, and so far as histological tests enable me to judge, are perfectly similar in composition to the homogeneous semitubular matrix derived from the former, in which ossification occurs to form the permanent rays. Active metabolism evidently occurs at the base of the fin-folds about the time the permanent rays are in process of development, for the reason that after the stratum of fibers becomes covered externally by mesoblast in this situation they rapidly atrophy leaving nothing but the semitubular rudi- ments of the permanent rays, crescentic in section, which now lie between the epiblast and mesoblast resting upon thickened tracts of the latter internally and which radiate toward the mar- gin of the permanent caudal fin-fold ; the proximal ends of these mesoblastic cores rest upon the distal end of the upturned chorda. The segmentation of the permanent rays has not been traced, but this evidently occurs before ossification has gone very far, as it is manifested quite early in the caudal rays of certain types. It .is doubtless due in part to the bendings which the rays suffer while in use. The rudiments of these rays are imperfectly tubu- lar in all forms, spines also having such a form at first, thoug frequently these have an external layer added by coalescence with dermal plates or denticles. The main conclusion, therefore, at which I have arrived in this investigation is the following : that it is the mesoblast which is involved in giving origin to the fibrous embryonic rays and that that layer also effects their transformation into the rudiments ot the permanent rays, and not the epiderm or embryonic integu- ment, as heretofore generally held by anatomists. The whole history of the fin-folds in fact favors such a conclusion, since the horny fibers develop between the corium and epidermis or em- bryonic skin, in the plane of the protomorphic line of Huxley. The fin-folds of embryo fishes, it should be borne in mind also, are at first wholly epidermic, the corium or true skin being only developed during the later-larval or post-larval life. Be SS n TE.

[February, the fin-folds, beside some scattering stellate mesoblastic cells which very possibly may be the pterygoblasts, which either them- selves give rise to the embryonic rays or are indirectly concerned, together with the surrounding tissues, in pouring out such a homogeneous secretion. Such homogeneous substances I have found in other cavities in embryos, especially in the brain; in such cases I have been inclined to attribute their presence to the action of reagents, as extractive matters, as homogeneous, har- dened acid-albumen, in short. The early advent of mesoblast into the fin-folds is at any rate a settled point, the stellate cells which wander outwards being mesenchymal, according to the ter- minology of the Hertwigs. In embryos of Scomberomorus I do not find the secretion noticed by Emery, homogeneous during the lophocercal condition, but loosely granular, more like the fine plasmic corpuscles found by me between the vitellus and zona radiata of the egg of Amiurus,. At any rate I am not inclined to believe, after weighing the foregoing facts, that there is the slightest ground for the assumption that the fin-rays of fishes originate from the primary epiderm or larval integument, but that they arise from the mesoblast, as their position and first vascular supply would indicate. The distinction between the fin-rays as exo- skeletal, from the other bones as endoskeletal, therefore breaks down on embryological grounds; for both are clearly of mesoblastic origin, as is further proven by the mode in which the insertions of the muscles which move the fin-rays originate— Fon A. Ryder. PSYCHOLOGY. Docs As NEWSPAPER CaRRIERS.—A very common thing on all the Connecticut railroad lines is for accommodating train men to throw newspapers off the trains at or near the houses of subscri- bers living on the line of the road at a distance from the stations. In many instances dogs have been trained to watch for the cars and get these papers, and country dogs, it is noticed, take quite an active interest in the affair. Over onthe Naugatuck road some one has had the curiosity to inquire into this matter of dog mes- sengers. Mr. Philip McLean, proprietor of the Gate House, on the Thomaston road, has a dog who goes a mile and a half every morning to meet the train. The paper was formerly thrown off by the brakeman on the last car, and there the dog watched for it. Lately it has been thrown from the baggage car. The dog appeared angry at the change, barked furiously, and waited sul- lenly for some time before going on his errand. He has not yet become reconciled to the new way of delivering his paper. Below Derby a dog has acted for several years as newsboy for a number of families. The papers are thrown out of the cars under full speed. Whether one or a large bundle of them, the dog is able to lug them off, making good time back. Another dog who has become a veteran as newsboy and cannot now, from age and rheu- REE eieaa ss anoni i NEN T ach nira r gas ee en e = a a a EEUE I IDEE eee ARON 1885.] Psychology. 205 matism, get down to the cars, has in some way managed to train a younger dog to do his work. Edward Osborne, residing below Naugatuck, has a dog who regularly meets the early morning train. The house is a mile away from the railroad, and the dog never leaves on his errand until he hears the train whistle at Bea- con Falls station. Then he starts on a run and waits at the same spot always, with his nose poked between the palings of a fence and his keen eyes watching for the flying paper. A story is told of one dog that was first taught to bring a certain New Haven paper, and when his master changed to another could not be in- duced to carry the new one. This is unlikely. Another story is that the late Senator William Brown, of Waterbury, had a pet dog that could readily distinguish the whistles of the New England engines from those of the Naugatuck, though running on a par- allel track at the same time side by side. The faithful dog always found his train and car, and stood in waiting for the Hartford Times, which he carried home to his master for many years.— Hartford (Conn.) Times. HEARING AND SMELL IN Ants.’—In the investigation of the senses of the lower animals, especially of invertebrates, the best efforts of the student are often rendered inconclusive from the fact that, for aught we know, the sense-organs possessed by them may respond to vibrations which produce no effect upon us, and thus they may possess senses of which we have no idea, though they may lack what we can identify as hearing, taste, or smell. So long. as a creature possesses eyes, we feel sure that it sees, though we may know that its perceptions are very limited; but it will not do to say that an animal cannot hear, only because it cannot hear sounds audible to us. For this reason Sir J. Lubbock carefully guards himself from the assertion that ants cannot hear; although all attempts to induce them to take notice of sounds audible to us proved failures. Not content with trying the most intense and the most acute sounds upon a colony of ants, and also upon single ants, he endeavored to ascertain whether ants could produce sounds intelligible to themselves, though inaudible to us. To this end placed some honey upon one of six small pillars of wood set upon a board frequented by the members of a domesticated colony of Lasius flavus. Three ants were placed at the honey, and then imprisoned near it; then three others, which were also imprisoned. Numerous ants were moving round the board in search of food. and Sir J. Lubbock reasoned that if ants can make any sound in- telligible to other ants, the imprisoned ants would tell the search- ers of the food. On the first occasion only seven ants found the honey in three hours—no more than visited the pillars which had no honey. But when the ants which had eaten the honey were 1 Résumé from the Revue Scientifique, of an extract from the work of Sir J. Lub- bock, entitled Ants, Wasps and Bees, Experimental studies on the organism and _ habits of hymenopterous insects. 206 a General Notes. [February, freed, fifty-four ants found the honey in half an hour. Other days of experiment resulted in the same manner. Thus it became evi- dent that, if the imprisoned ants made sounds inaudible to us, those sounds had no meaning to their companions. A sensitive flame was not affected by anything the ants did, and a microphone, though it made their footsteps audible, gave no indication of any other sound. Remembering, however, that all vibrations be- tween 35,000 per second, the highest perceived by the human ear, and 470,000,000 per second, which produce the sensation of red light, are only perceived by us as heat; and mindful also of the curious sense organs present upon the antenna, Sir John Lubbock is still of opinion that ants have a sense cognate to what we call hearing. These antennal organs are of two kinds, one of which occurs in other insects, but the other seems to be peculiar to ants. The latter consist of an exterior and interior chamber, connected by a long narrow tube. A nerve ends in the interior chamber. The whole apparatus resembles a stethoscope, and Professor Tyndall and Sir J. Lubbock are of opinion that it serves for a similar purpose. Besides a group of these in the terminal segment of. the antennz, there are one or two in each succeeding segment. Moreover, ants have an apparatus consisting of several serrated ridges at the junction of some of the abdominal segments, and similar to an organ which in Mutilla europea produces sounds audible to us. The inference is, that since Mutilla is not very distantly related to the ants, the apparatus possessed by the latter serves a purpose similar to that possessed by the former. Experiments made upon the sense of smell showed that ants ear very sensitive to odors that produce the sensation of scent in us. PsycHICAL ResEARCH’.—The Proceedings of the Society for Psychical Research are certainly remarkable amongst the litera- ture of the present century and, rightly considered, are amongst the most interesting. The reports of the various committees are published primarily for the edification of the members, but they also court public criticism, and as a simple matter of fact they are worthy of all attention. It has been known for a long time that certain phenomena do occur amongst a certain class of per- sons which are, to say the least, inexplicable, for though it may be urged that collusion and connivance, conjuring and deceit, may be practiced occasionally, there is now a mass of trustworthy evidence demonstrating the truth of the hypothesis that thoughts are transferred from one person to another. It must be conceded that until we can fully explain the mech- anism of thought as found in any individual, that we have no right to say that it is impossible for one person to transfer his 1 Proceedings of the Society for Psychical Research, Vol. d ul.

Electricity has been known and utilized for years, but we are no nearer to a definite idea of what it really is than we were in the time of Volta and Galvani. There is ample material to enable us to form a good working hypothesis, and so also by a parity of reasoning there is quite sufficient to enable us to affirm that there is more in thought transference than those unacquainted with the phenomena have been willing to allow. In the second report of the committee on thought reading, or, more properly, thought trans- ference, it is taken as established that “ much of what is popularly known as ‘thought reading’ is in reality due to the interpreta- tion by the so-called ‘reader’ of signs, consciously or uncon- sciously imparted by the touches, looks or gestures of those present, and that this is to be taken as the prima facie explanation whenever the thing thought of is not some visible or audible object, but some action or movement to be performed,” and also that “there does exist a group of phenomena * * * which consist in the mental perception, by certain individuals at certain times, of a word or other object kept vividly before the mind of another person without any transmission of impression through the recognized channels of sense.” The evidence the society is able to offer is fairly conclusive, and is certainly of such a char- acter that it must be fairly met before its assumptions can be pooh-poohed in the orthodox manner. coincidence, when the chances against success were fifty to one, up- wards of forty per cent of the guesses were right, if the second’ and an occasional third response are admitted; but if the tests are confined to the first guess only the percentage is twenty-one, when, according to the laws of chance, the correct answers would 208 General Notes. [February, have been less than two per cent. The committee pertinently observe that their experiments derive much strength and cohe- rence from their very multitude and variety ; they have eliminated, as far as possible, the hypothesis of coilusion, chance coincidence, and muscle or sign reading, and they are left with an accumula- tion of experiments which indicate clearly that thought transfer- ence is a possibility, or that there is some flaw in the evidence which they have been unable to discover. The third part of the Proceedings contains the first report of the committee on “ mes- merism” and the first report of the Reichenbach commit- tee, both of which will be found to contain a great deal more than is dreamt of in the philosophy of the ordinary world, though the committees respectively declare in the one case that they pre- fer to defer the publication of results, until a more complete re- production of the experiments of others with added tests of their own have afforded a wider basis for discussion. The society has fairly established its demand for an inquiry by the scientific world, ever the most skeptical, and properly so, for it is the duty of science to reject everything that is not proven, while desirous, nay anxious, to take up any line of investigation that may lead to discoveries the ultimate result of which it cannot foresee.—Zuglish Mechanic. ANTHROPOLOGY! Tue Proto-Hetvetians.—The lowering of the levels of lakes Neuchatel and Bienne by the ‘so-called “correction” of the Jura (a work undertaken for the prevention of floods) though it has by no means added to their beauty, is proving an immense gain to archeology. It has laid bare many Lacustrine stations, homes on the lakes of Central Europe, and to whom has been given the apt name of Proto-Helvetians, they serve to correct old theories and suggest new conclusions. An idea of the richness of the finds made during the last ten years may be formed from the fact that the number of relics brought to light on lakes Bienne and Neuchatel since 1873, amounts to 19,599, of which 13,678 have been acquired by various Swiss museums. Nearly 6090 have been added to the collection of Dr. Goss, at Neuve- ville, on Lake Neuchatel, who has undertaken many explo- 1 Edited by Prof. Otis T, Mason, National Museum, Washi pc sé 1885. | Anthropology. 209 rations at his own cost, and in whose presence some of the most valuable discoveries have been made. He now owns the richest private collection of Lacustrine relics in existence, and at the request of many brother antiquaries, he has published thirty- three phototype plates, reproduced from photographs taken by himself, of his more important finds. The number of the objects depicted is nearly 1000, and being fac-similies of the originals, and half, and in some instances three-fifths, of the natural size, the illustrations, elucidated by the doctor’s suggestive comments, are almost as interesting and instructive as a visit to the collec- tion at Neuveville, according to Professor Morel, of Morges, a high authority, the most valuable, if not the largest, known to archeology. Notwithstanding the doubts that have been expressed to the every new discovery lends additional confirmation. There are Swiss lake dwellings where not a vestige of metal has been met with. There are others in which a few tools or arms of pure copper, and, exceptionally, of bronze are found. It is therefore a safe inference, as it is antecedently probable, that the use of cop- per preceded the use of bronze. In other stations, again, bronze preponderates and stone disappears. Last of all comes iron, first as a precious metal, ornamenting and encrusting the bronze which in the end it was destined to replace. A noteworthy fact is ‘ the comparative rareness of ruined villages of the age of bronze. On Lake Bienne there have been found the vestiges of thirteen villages of the stone age, and two only of the age of bronze; but the latter are far the more extensive. VOL, XIX.—N®. IT. 14 \ i 4 210 General Notes, [February, that mysterious conflagration in which perished a civilization as old as that of Egypt, and as interesting as that of Hellas. ere is a marked difference between the habitations as between the implements, of the age of stone and the age of metals. The former, if more numerous, are less extensive; they were but from fifty to one hundred yards from the shore; the piles which formed their foundations are short, and made gen- erally of entire trunks of trees. Between the piles are found fragments of stag’s horns, broken stones, pieces of rude pottery, and bones of animals. The stations of the age of bronze, on the contrary, were large villages, built at a distance of from 200 to 300 yards from the shore, on large, long, and often squared piles, between which are found remnants of fine pottery, and often entire vases, It is lower down, under the mud which has accu- mulated about the piles, that the great finds have been made. One of the most remarkable stations is the recently discovered village of Fenil. Although the exploration is not yet com- pleted, more than thirty articles in pure copper have already been found, and as similar relics have lately come to light at Greng, on lake Thorat, at Peschiera, on Lake Garda, and in other places, antiquaries may ere long deem it expedient to add to the three recognized ages an age of copper. The minute and systematic researches which have been made on the shores of Swiss lakes, albeit they have brought to light such a multitude of priceless relics, have not yet resulted in the dis- covery of a single Lacustrine habitation. A few charred planks and beams showing that they were destroyed by fire, are all that remain. Fortunately, however, we are not without light on the subject. A short time ago there was discovered in a marsh at Schussenried, in Wurtemburg, a well-preserved hut of the age of stone. The flooring and a part of the walls were intact, and, as appeared from a careful measurement, had formed, when com- plete, a rectangle, ten meters long and seven meters wide. e ut was divided into two partments, icating with each other by a foot-bridge, made of three girders. A single door looking toward the south, was a meter wide, and opened into a room 6.50 meters long and four meters wide. In one corner lay a heap of stones which had apparently formed the fireplace. This room was the kitchen, “the living room,” and probably a night refuge for the cattle in cold weather. The second room, which had no opening outside, measured 6.50 meters long and five meters wide, and was no doubt used as the family bed- chamber. The floors of both rooms were formed of sound logs, and the walls of split logs. This, be it remembered, was a hut of the stone age. It may be safely presumed that the dwellings of the bronze age were larger in size, and less primitive in their arrangements. At both periods the platform supporting the house communicated with the shore by means of a bridge (prob- 6. Expression and physiognomy of the Italians, «« 7.

CALDWELL’S Automatic Microtome.2—This machine has been devised to save labor to the histologist by cutting a very great number of sections suitable for microscopic investigation in a very short time. The machine is worked by hand and may easily be made to deliver in one continuous band, accurately cut sec- tions at the rate of 100 per minute. To use it, however, to the best advantage, it is well to drive it by means of some motor, the fly-wheel being already provided with a groove for thé reception of the cord coming from the motor. Where there is sufficient pressure and supply of water, a simple form of water motor seems the most appropriate and least expensive. Method of using the Microtome—Place one of the cylindrical vessels supplied with the machine upon a piece of paper on a glass plate, and pour into it sufficient melted paraffine to fill it. As this cools the paraffine will contract, and will leave a hole, which must be filled up with more melted paraffine. Melt a small quantity, say an ounce, of imbedding material in some suitable vessel; a small copper pan or a porcelain crucible answers very well, if care is taken not to allow it to become hot- ter than is sufficient to thoroughly melt it. Take a piece of glass and smear it with a very small quantity of glycerine, to prevent the imbedding material from sticking to it. Then pour the melted material on the glass in small quantities at a time, so as to get a layer nearly a quarter of an inch thick. This when cut up into Suitable pieces with a knife does very well for imbedding small objects. If larger objects are required, it is well to have two pieces of brass of the form shewn in Fig. 5, which, when placed together, will form a cavity half an inch in depth and of any de- sired length up to an inch or more; this cavity may be filled with the melted material in the manner already described, and the object to be cut must then be placed in position while the mate- rial is fluid. Zz is well to cool the material as rapidly as possible by placing it in water as soon as it is sufficiently set. From the cake thus formed, or from the piece cast in the mold, cut the piece of the material containing the object, and with an old scal- pel, heated in a Bunsen flame, melt a small hole in the paraffine contained in the cylindrical vessel (Fig. 1 æ), and insert the piece of imbedding material containing the imbedded object; then with the heated scalpel melt a little of the paraffine round the base of the projecting piece, so as to give it firm support, and allow this to become thoroughly set. : Now remove the large brass plate from the top of the micro- tome (Fig. 1 4) and insert the vessel containing the imbedded object in the tube for its reception, having first oiled the tube 1 Edited by Dr. C. O. WHITMAN, Mus. Comparative Zoology, Cambridge, Mass. ? Quart. Jour. Micr. Sc, XXIV, Oct., 1884, p. 648. 216 General Notes. [February, slightly to prevent the vessel from sticking. Next with a sharp knife cut the material with the object imbedded in it, so that all its opposite sides are parallel, This is extremely important. Replace the top plate and fix the razor in the holder provided for the pur- pose. The clamp is so made that if a little care is taken the plate holding the razor should then be moved so that the edge of the razor is close to and quite parallel with the mass of material to be cut? (Fig. 3). The plate should then be clamped by the screws at each side of it. A few turns of the fly-wheel will now bring the razor in contact with the object to be cut. The band of black ribbon (Figs. 1 and 3 @) is now to be placed so that the end of it should be just above the razor and clamped in that posi- tion. When the handle is turned the sections should come off the razor in the form of a ribbon. The ribbon of sections will not find its way. to the continuous black band without assistance. With a needle in a handle or with the point of a scalpel pick up the end of the ribbon, when a sufficient length of it has been cut, and place it on the black con- tinuous band, up which it will travel. When it reaches the top of the band suitable lengths may be cut off with a pair of scis- sors. It may be found that the black band travels either too- slowly or too fast. Its speed may be varied by moving the ring (Fig. I é) up or down upon the vertical brass arm—upwards if it is moving too fast, downwards if too slow. A frequent cause of failure in the proper movement of the band is, that the ebonite roller at the bottom of it is allowed to press against the razor; this must be avoi : = The makers of the instrument have nearly completed an automatic machine for _ — razors, since it has occurred to them that this is an operation which may performed with much greater accuracy by mechanical means than by hand.

This may be done so as to allow the clicks to engage one-half, one or several teeth of the ratchet wheel as may be required. When arranged for one half tooth, the sections will be z>49; of an inch (.0025™") in thickness, when arranged to engage a whole tooth sooo Of an inch (.005™") and soon. At first it is well to use a whole tooth, as when thinner sections are cut so much depends on the sharpness of the razor. After cutting for some time the machine will suddenly stop, the object ceasing to rise when the handle is turned. This means that the full extent of the microm- eter screw has been reached. It is necessary then to turn the large milled head (Fig. 2 c) downwards, which will allow the car- riage containing the object to fall to its lowest limit. It will be , necessary now to raise the socket (Fig. 2 g) in which the object is held so as to be in position to come in contact with the razor. This milled head (Fig. 2c) is useful for rapidly getting the object in proper position and avoiding considerable loss of time in turn- ing the handle. The frame (Fig. 2) which holds the socket is arranged with two quadrants, so that the socket may be set at any angle desired, and may be clamped with the milled head underneath it. This is for use when the object has not been sym- metrically imbedded. The nut (Fig. 17) is for tightening up the spring which draws the carriage of the machine back after hav- ing been pulled forward. In case this does not work properly, it is only necessary to unloose the two screws and with some strong but blunt pieces of steel placed in the two holes, to rotate the nut so as to give a proper tension to the spiral spring. en this is done the screws should be tightened up again to keep the nut in place. The lock nuts (Figs. 1 and 2 s) should be screwed up suffi- ciently tight to barely prevent the carriage from falling by its own weight, so that when the milled head (Fig. 2 c) is screwed down a slight pressure with the finger is necessary to make the car- riage fall. To arrange the machine for cutting different sized blocks of material, it is only necessary to raise or lower the arm (Figs. I and 47). When this arm is in a vertical position the machine is arranged for its maximum traverse. When turned to the right and placed horizontally it is at its minimum traverse, The cord, however, must always be in the groove of the wheel, %. It is important to keep the strings which give motion to the endless band in proper position: The string (Fig. 1 /) should go from the end of the wire, m, round the groove, z, in the pulley and thence to the elastic band, 0. The elastic band, 0, should be stretched and placed over the hook attached to the arm, 7, care 218 General Notes. [February, being taken that the shorter end of the arm, /, is uppermost. The string, g, should be tied to the stud upon which the arm, $, is supported, going thence round the groove, r, of the pulley, and back again to the hook at the longer and lower end of the arm, $, to which it should be tied. | Method of preparing the slide—Make by the aid of heat a vis- cid solution of white shellac in light colored creosote. Spreada smooth, thin and even layer of this solution on a clean dry slide with a camel hair brush or with the little finger. Arrange the | ribbon containing the sections on this slide while moist, and place it in the dry shelf of the water bath, which should be at a tem- perature slightly above the melting point of the imbedding ma- terial used. It should be left here until the creosote has evapo- rated and the imbedding material melted. Now allow the slide to cool, and then wash it with turpentine until all the imbedding material is dissolved. Canada balsam in chloroform or turpen- tine and the cover slip may now be applied in the usual manner. For convenience of mounting it is extremely important that the ribbon of sections should be quite straight, and in order to en- sure this it is necessary that the sides of the imbedding material from which the sections are cut should be quite parallel. The straight ribbon, when obtained, should be removed to some clean surface and there cut into lengths appropriate to the size of the cover slips used. It will be found convenient to use cover slips at least two inches long; indeed, a useful length for slides and oid slips is six inches for the former and four inches for the atter. ~ A method of imbedding the specimen to be cit.—After the speci- men has been stained it should he left in ninety per cent alcohol for a few minutes, and thence transferred to absolute alcohol, there to remain until all the water is extracted. The length of time necessary for this varies greatly with the size of the speci- men. A three day chick, for instance, will require about an hour, larger specimens a day or more, in which case the absolute alco- hol should be changed occasionally. Some tissues may be trans- ferred directly from the absolute alcohol to turpentine, and thence in about two hours to the melted imbedding material. For deli- cate tissues, however, the following process, though longer and more troublesome, is greatly preferable. With a pipette intro- duce some chloroform to which two or three drops of ether have been added, under the alcohol in which the object is lying. The object will then float for some time at the junction of the alcohol and chloroform, and will finally sink into the chloroform when _ Saturated with it. If, as often happens in the case of embryonic : tissues, the object is lighter than the chloroform, it is not easy to x teli when the saturation is complete, but generally on shaking the bottle a saturated tissue can be temporarily covered by the chlo- 1885.] Scientific News. 219 roform, while tissues containing alcohol keep steadily on the surface. When the tissue is saturated with the etherized cloroform it should be transferred to pure chloroform and there left for a few minutes. Then drop in some pellets of soft paraffine and leave it for two hours or more, shaking occasionally. The whole should then be poured into a small melting pot and a quantity of imbedding material added. The melting pot should then be placed in the water bath at a temperature of about 60° C., and there left until all the chloroform has evaporated, which may be determined by the absence of smell of chloroform on shaking. If much imbedding material is required this process takes a day or two; it is therefore better, when the solution of imbedding material is fairly strong, to take out the tissue and put it direct into pure melted imbedding material. In any case no chloroform must remain in the material to be cut, as it makes it brittle.

The germ theory of disease in its earliest slimmerings appeared centuries ago; but William Budd was the first to see further than his contemporaries, and his grand gener- alization has been confirmed by experiment. So long ago as 1817 Schwann demonstrated that putrifaction was the work of living organisms, and in 1863, Pasteur followed with his far more elaborate researches. A high tribute was paid to Koch’s re- searches. The immunity enjoyed by the vaccinated, Tyndall accounts for on the supposition that contagia being living things, demand certain elements of life, and when those are exhausted they can no longer live. To exhaust a soil, then, a parasite less vigorous and destructive than its virulent representative may suffice, and once the soil is exhausted the virulent type is power- less to injure. Such in substance is the germ theory of disease. —At the Newport meeting of the National Academy of Sciences, Mr. Fairman Rogers referred to Mr. Muybridge’s ex- periments made last summer on the motions of animals by instan- taneous photography.

INDIAN: CORN AND THE INDIAN. _ BY E, LEWIS STURTEVANT, M.D. i oe is the product of an ancient American civilization, which if small as compared with that of to-day, yet was capable of achieving results which we of the présent gladly appropriate. It constituted the daily food of tribes which have now disappeared from existence, and at the time of the discovery was a cherished plant throughout the temperate and the tropical regions of America, and finds mention in nearly every account of the voyager, or hardy explorer who penetrated beyond the con- fines of the coast. The plant has never been recorded as being found in a wild state, but has existed in numerous varieties from time immemorial, and the leading races grown to-day can find more or less certain identification in the imperfect descriptions of _ the species grown by the Indians. It is a general observation that varieties are produced through the influence of the wants and the choice expressed by civiliza- tion, and hence we may conclude that the vast number of varie- ties of maize that formerly, as now, existed, have been derived through the appreciation of a culture that was under the influence of varied and critical consumers. In Central America the condi- tions existed for producing varieties, and hence wheresoever the home of the native plant is to be located, from this central region must we preferably look for the origin of the domesticated maize- plant, as we now know it, or at least of some of its races. We have evidence in the tropical nature of the plant that it was orig- inally derived from a country where winters were unknown, or were mild. The few traditions that we have found recorded by the Indians all point towards Central America, as where it is VOL. XIX.—No. 111, 15 bad 226 Indian Corn and the Indian. { March, stated in the Popol Vuh that four barbarians, the Fox, the Jackal, the Paraquet and the Crow, guided to Paxil or Cayala, the “land of divided and stagnant waters” where “the white and the yellow maize did abound,” and apparently a civilized country, and where the use of maize for meal and for preparing “nine drinks ” was acquired. The Navajoes have the tradition that a turkey hen came to them flying from the direction of the morning star, and shook from her feathers an ear of blue corn (Bancroft, Native Races, 111, 83). The Indians of Massachusetts, as Roger Williams writes, have a tradition that the crow brought “them at first an Indian graine of corne in one Eare, and an In- dian or French Beane in another, from the great God Kautau- towits’ field in the Southwest, from whence they hold came all their Corne and Beanes ” (Key to the Lang. of Am., 1643, p. 144, Narragansett Club ed.). The antiquity of maize, as well as its importance, is attested by the circumstance of its connection with religion, and its acquire- ment of sacred characters. Centeotl, in Mexico, was goddess of maize, and hence of agriculture, and was known, according to Clavigero, by the title, among others, of Tonacajohua, “ she who sustains us.” Sahagrun writes of the seventy-eight chapels of the great temple at Mexico, that the forty-fifth edifice was called Cinteupan, and korrin was a statue of the god of maize. Tor- quemada also says. “ there was another chapel dedicated to the god Cinteutl, called Cinteupan, he was the god of maize and of bread,” and Charnay (1880), who quotes the above references, found a statue bearing sculptural representations of ears of maize. The Mexican god Tlaloc is represented by Ixtlilxochitl “ in the picture of the month Etzalli with a cane of maize in the one hand and in the other a kind of instrument with which he was digging the ground” (Bancroft, Native Races, 111, 325), and vari- ious ceremonials in relation to maize are recorded by many of the early Spanish writers upon Mexico. In Peru the maize of Titiaca was considered sacred, and was distributed throughout the kingdom in small parcels to impart a portion of its sanctity to the granary wherein it was stored — (Garcilasso, Royal Com. Hak. Soc. ed., 1, 288), and in the garden so of the Inca: “There was also a iage field of maize, the grain ~ they call quinua, pulses, and fruit trees with their fruit; all made ETE 1885.] Indian Corn and the Indian. 227 of gold and silver ” (¢., 1, 283). Acosta also describes ceremo- nies in which maize took part. It seems certain that the Indians of America were often agri- cultural, especially under circumstances where the soil was favor- able, and where tribal strength admitted of the protection of their crops, and that maize was cultivated not only sufficient for their own wants but also to admit of furnishing supplies to others in need. We think it well to bring together evidence to this effect connected with the northern portion of our country. In the Icelandic Saga, in 1006, Karlsefne arrived at a place called Hop, at the mouth of a river, which may as well be the St. Lawrence as any other, as this seems to answer the conditions of the narrative, and “they found there upon the land self sown fields of wheat, there where the ground was low, but vines there where it rose somewhat” (Icelandic Sagas, Prince Soc. ed., p. 54), and “sent out two Scotch people to explore; when they returned they brought back a bunch of grapes, and a new sowen ear of wheat” (Voyages of the Northmen, Prince Soc. Pub., p. 51). “The same year (1002) [Rafn.], sailing from Greenland westward, Thorwald, brother of Lief, reached the wintering place in Vinland [mouth of the St. Lawrence]. The following sum- mer * * * * on an island far westward ‘met with a wooden Kornhjalmr,’ but saw no other signs of inhabitants, nor of wild beasts ” (Pickering Chron. Hist. of Pl., p. 664). In 1535, Jacques Cartier, at Hochelega, now Montreal {the island far westward ?], “began to find goodly and large fields, full of such corn as the country yieldeth; it is even as the millet of Brazil, as great and somewhat bigger than small peason, wherewith they live even as we do, with ours” (Pinkerton’s Coll. of Voy., XII, 651), and else- where he says: “At the top of the houses were garners where they kept their corn, which was something like the millet of Brazil, and called by them Carracony (Tytler’s Disc. of N. Coast of Am., p. 46), and he further states that the town was situated in the midst of extensive corn fields and the houses were large and commodious (Cartier’s Voy. Hak. Coll.). Another name for the corn seemed to have been offici, and he also adds: “ They have also great store of musk-millons, pompions, gourds, cucum- bers, peason and beans of every color, yet differing from ours” (Pinkerton’s Voy., xu, 656). In 1613 Champlain found at Lake Coulonge, on the Ottawa river, a crop of maize growing (Park- A3 228 Indian Corn and the Indian. [March, man, Pioneers of France, 348) in this northern latitude, and on the Ottawa river, 1632, mentions also pumpkins, beans and French peas obtained recently from the traders (24., 352). This year on Lake Huron, Champlain saw fields of maize, idle pumpkins ripening in the sun, and patches of sunflowers (20., 366). “ The Adirondacs,” says Colden, “ formerly lived 300 miles above Trois Rivers; * * * * at that time they employed them- selves wholly in hunting, and the Five Nations made planting of corn their business (Hist. of the Five Nations, Lond., 1747). In 1615 Champlain invaded the Iroquois country, the present New York, and saw the Iroquois at work among their pumpkins and maize, gathering their harvest, for it was the month of Octo- ber. In 1653 Le Moyne navigated Lake Ontario, and in the country of the Senecas had given him “ bread made from Indian corn, of a kind to be roasted at the fire.” In 1687, in an invasion into this country by de Nouville, some 400,090 minots, or 1,200,- 000 bushels of corn were said to have been destroyed (Doc. Hist. of N. Y., 1, 238); and in 1696, Frontenac, in the country of the Onondagas, spent the 7th, 8th and oth of August with his army in destroying the growing corn which extended from a league and a half to two leagues from the fort (zd.,1, 212). In 1779, when the army under Gen. Sullivan came to the vicinity of Cay- uga and Seneca lakes, they found the lands cultivated, yielding abundant corn, extensive orchards, and a regularity in the arrange- ments of their houses which announced prosperity and enjoy- ment of property ; the houses were framed and painted and pos- sessed chimneys (Trans. N. Y. Agr. Soc., 1850, 380), and Gen. Sullivan says of the Indians of the Genessee valley that their fields) were fruitful with “every kind of vegetable that could be perceived,” and another record catalogues “corn, beans, peas, squashes, potatoes, onions, turnips, cabbages, cucumbers, water- melons, carrots and parsnips (Conover’s Early History of Gen- eva, N. Y., p. 47). When Verrazzano, 1524, visited the New England coast he found the Indians would trade only at a distance, and when he landed he was welcomed with the war-whoop and clouds of arrows. This is worthy of note as showing that the conditions were unfavorable to agriculture. When Capt, John Smith visited _ the coast he enumerates “ pompions, gourds, strawberries, beams, _ pease and mayze (The Desc. of New England, 1614, p, 16; Peter mite Fees siii ig TE E 1885.] Indian Corn and the Indian.” 229 Force Coll. of Tracts, 11), and mentions “ Mattahunts, two pleas- ant isles of groves, gardens and corne fields a league in the sea from the mayne” (2., p. 5), and this indicates a change in the local conditioris rather than a change of habits in the people. Champlain, in 1605, describes the method of storing maize in large grass sacks buried under ground in dry places, and mentions the methods of field cultivation at the mouth of the Kennebec and Cape Cod, and finally says that after pass- ing Cape Cod they found much land well tilled in corn and other grains (Champlain’s Voy., Prince Soc. ed., p. 121, etc.), and in 1636, when the English made an attack on the Indians of Block island, they found “ two hundred acres of land were under cultiva- tion, and the maize, already partly harvested, was piled in heaps to be stored away for winter use (Bryant’s Hist. of the U. S., 11, 4). When the pilgrims first landed they sent out Miles Standish to explore, and “from thence [Truro] we went on, and found much plain ground, about fifty acres, fit for the plough, 7 — signs where the Indians formerly planted their corn, * We went on further and found new stubble, of which Beh had gotten corn this year” (Young’s Chron. of the Pilg., 130, 132). This same Nov. 16, 1620, they found “ divers fair Indian baskets filled with corn, some whereof was in ears, fair and good, of divers colors” (Morton’s New Eng.’s Memorial ed., 1826, p. 40), and Mouart says of this corn, “some yellow, and some red, and others mixt with blue” (Mass. Hist. Soc. Coll., Ser. 1, vin, 210). Higginson (1629) mentions also the color of the corn in New England, as “ red, blew and yellow, &c.; and of one corne there springeth four or five hundred” (New England’s Planta- tion, 118, Mass. Hist. Soc. Coll.) ; and Josselyn, before 1670, de- scribes not only corn of various colors, but beans, pumpkins, squashes, etc. Lescarbot (Hist. Nouv. France, ed. 1612) says the Indians of Maine, like those of Virginia and Florida, plant their corn in hills, along with beans. At first the Swedish settlements at New Jersey and Pennsylva- nia (1638) were obliged to buy maize of the Indians for sowing and eating (Peter Kalm, Trav.), and in 1633, on the Delaware river, obtained from the Indians corn and peas (Hazard’s Annals of Pa., 32). As showing the importance of corn to the Indians, we may note that Rev. John Campanius, in his Delaware and Swedish translation (1696) of the Catechism, accommodates the : of the Delawares of Ohio: 230 Indian Corn and the Indian. [ March, Lord’s Prayer to the circumstances of the Indian thus: instead of “give us our daily bread,” he has it, “a plentiful supply of venison and corn” (6. 101). In 1609 Hudson mentions “a great Seed of maize” near where is at present Renssellaer county, N In Vicma Grenville, in 1585, “ with hasty cruelty ordered the. village to be burned, and the standing corn to be destroyed” (Bancroft, Hist. of the U. S., 1, 96); Heriot, and Strachey men- tion maize, as also John Smith and. many others, and the method of Indian culture is described in “A True Declaration of Vir- ginia,” 1610. In the expedition of Narvaez to Florida, in 1528, maize was found in abundance. In 1544 the Indian tribes everywhere on the route of De Soto’s expedition from Florida to Alabama, Missis- sippi, Missouri and westward were found to be an agricultural people, subsisting largely upon maize, and in De Bry’s collection, 15y1, Plate xxt, Vol. 11, represents Florida Indians of both sexes engaged in the cultivation of the fields. Indeed, there is hardly an account of Florida in the sixteenth century but what mentions inferentially or otherwise maize, beans and pumpkins as being produced in great abundance. In 1540 Coronado started from Mexico ‘for an expedition north- ward, and everywhere, where the soil was suitable, found maize and other products of cultivation, even to his most northern point, which is probably the now State of Kansas, a country well watered by brooks and rivers, * * * the soil was the best strong black mold, and bore plums like those of Spain, nuts, grapes and excellent mulberries. The inhabitants were savages, having no culture but of maize.” Marquette in 1673, Alouez in 1676 and Membré in 1679 all mention the cultivation of maize by the Illinois Indians, and in 1680 Hennepin found corn everywhere in his journey from Niagara to the Mississippi river. e have now briefly, by the use of a few only of the authori- ties at our command, shown the existence of the cultivation of maize throughout a large part of the borders of the present Uni- _ ted States. A few more references of a later date may serve to impress the fact that the Indians were anciently an agricultural race where the conditions for agriculture were favorable, In Gen- ‘Wayne’s letter to the Secretary of War, August, 1794, he speaks “The margin of those beautiful : _ Tivers, the Miami's, of the lake and Au Glaize—appear like one 1885.] Indian Corn and the Indian. 231 continued village for a number of miles, both above and below this place ; nor have I ever before beheld such immense fields of corn in any part of America, from Canada to Florida.” Pre- ceding this account, Carver, the celebrated English traveler, who traveled upwards of 5000 miles of the interior about the period of the Revolutionary war, writes that the Ottagammies, the Sau- kees and all the Eastern nations, were found growing Indian corn. In 1804 the Sioux of the Upper Missouri were found by Lewis and Clark cultivating corn, beans and potatoes, and indeed the references to Indian cultivation either directly by the ob- servers, or indirectly through antiquarian evidence, place beyond a doubt the existence of an agriculture often more or less rude, often more or less perfect, among the tribes of Northern Indians with irrigated fields and a systematized agriculture among some of the tribes of the Southwest. Let us note very briefly a few points to show that the North- ern Indians were intelligently desirous of securing agricultural products which would add to their luxury or support. We will — not refer to the Southern or Nahua tribes, for their possession of maize, beans, pumpkins, sweet potatoes, yams, Cassava, choco- late, peppers, tomatoes, etc., etc., in numerous varieties are suffi- cient evidence of their progress in agriculture, even if we refrain from mentioning the gardens of Mexico and Peru, which antedate the existence of similar institutions in France, if Hallam is to be credited, and in Mexico “ flowers were the delight of the people.” The melon is mentioned in 1494 as grown by the companions of Columbus at Isabella island, and this is their first occurrence in America. In 1535 Jacques Cartier speaks of the Indians at Hochelega, now Montreal, as having “ great store of muskmil- ions.” In 1540 Lopez de Gomara mentions melons as grown at Quivira, in the country of Tiguex, which appears to be some- where in the region of the present Arkansas, and in 1850 Anto- nio de Espejo found melons cultivated by the Concho Indians. In 1542 the army of the viceroy, sent from Mexico to Cibola, found the melon already there. Indeed melons are mentioned by the early visitors in New England, Virginia, Florida and the West. This rapid distribution of a desirable fruit is strong evi- dence in favor of the care the Indians gave to their fields, in securing and preserving seed.’ 1 We must remember, however, that by the older horticulturists the pumpkin was often called a melon. 232 Indian Corn and the Indian. [March, Peach stones were among the articles ordered by the Governor and Company of the Massachusetts Bay in New England in 1629. In 1683 Wm. Penn speaks of the Indian orchards of peaches about Philadelphia as bearing great abundance of fruit “ not inferior to any peach you have in England, except the true Newington.” Hilton, in 1664, speaks of peaches abounding in Florida, and Du Pratz, in his history of Louisiana, 1758, says the natives had doubtless got their peach trees from the English col- ony of Carolina before the French established themselves in Louisiana, and says that they were of the clingstone variety. In the destruction of the Indian settlement at Geneva, N. Y., by Gen. Sullivan in 1779, peaches are enumerated in Major Beatty's account of a near town called Kershong. Among the Indian products destroyed in this invasion, apple, pear and plum trees are also distinctly mentioned, and so remarkable was the town of Kendaia for its orchards, that it was called Apple-town. Wm. Bartram, in his travels in the South about 1773, speaks of the carefully formed orange groves of the Indians, and in one place of a cultivated plantation of shellbark hickory. The settlers of Michigan, in 1805, found here and there about the State orchards of seedling apple trees planted by the Indians, and which, though of great age, were healthy and productive. We thus see that the Indians were willing to exercise a forethought in growing plants which would produce only a long time after being planted. The cultivation of the potato was first introduced into New England in 1719, and its growing as a field crop is first men- tioned at Salem, Mass., in 1762. In 1779, on the authority of Moses Fellows, sergeant of the 3d N. H. regiment, under Gen. Sullivan, the soldiers destroyed, on Sept. 9, at the present Gen- eva, N. Y., the crops of the Indians, which included “ corn, beans, peas, squashes, potatoes, onions, turnips, cabbages, cucumbers, watermelons, carrots and parsnips.” Our citations are sufficient to call attention to the agricultural tendencies of the Indian population of North America, and jus- in their analyses our first remark, that where the circum- stances of climate and soil were favorable, and where the tribal strength was sufficient to protect the crops, the Indians were apparently a people who might properly be termed agricultural. It is this agricultural feature of the Indian character which oe tended to develop the many varieties and agricultural species of 1885.] {Indian Corn and the Indian. 233 maize. At the time of the discovery of the various regions of our country in detail, the Indians had already accomplished in the matter of improvement of varieties of maize what we are at present using, and we have no evidence, I speak after careful research, that any new forms of maize have appeared from our two centuries or more of civilized cultivation. The various agri- cultural species of maize, the flints, dents, softs, sweets and pops appear to be original forms; the subdivisions of these into local forms appear to have been about as well accomplished by the In- dians as by ourselves. The leading forms of maize, in all the cases where sufficient material has been collected for examina- tion, can be referred to an Indian original, and a more cursory examination into all the forms, seems to indicate that this Indian origin is common with all. If we ask the maize plants themselves to tell their own story, we have for reply : We are originally of a warm region, for our seeds require about 80° F. for their best germination, and our roots occupy only the hotter regions of the soil. We are of very ancient ori- gin, and many ages ago separated into several groups, for we now represent five different families, which do not easily fraternize and which resist attempts at mingling, to a more or less extent, but not reciprocally. We have been long domesticated, for we have lost the power of becoming feral, in our civilization we do not recognize our barbarian ancestry even by sight, we- have long ago separated into agricultural species for the conve- nience of man, we have withia each of our species given to man’s continuous asking varieties suited for his necessities to accom- pany him to regions of short seasons, and to regions unknown to our ancestry. We have varied for man as he has required new wants of us, yet we have maintained the traditions of our origin, when man has not compelled us to discard. We yet ask the temperature for our growth that our ancestors enjoyed; we yet ask that we shall not be subjected to shade. Upon unessentials we have yielded, perhaps after long repeated persuasion, to mold our product to man’s desire for quantity, to change our habit of bearing, to get along with a greater or less continuance of heat, to grow larger or smaller plants, to protect ourselves from the thieving of birds or insects, to abandon those agencies for our - own survival, from which care man has relieved us. We now 234 On the Evolution of the Vertebrata, [ March, consider ourselves as respectable and useful among man’s com- panions, and in our habits we would show the generations of cul- ture we have received. Leaving our plant and returning to human experience, we can summarize our view by saying that the problem of similarity of types with great structural diversity of kernel, is only soluble by influences which have had a very long period of time to work in; and the perfectness of the result attained is to be explained only upon the supposition of a very long period of intelligent selective action. It is very probable that a more intimate acquaintance with the facts concerning the development of a single domesti- cated plant, as gained from philological, physiological and re- corded data will some time or other tend to throw some light upon the antiquity of man and the direction and extent of his migrations. "rh VU ON THE EVOLUTION OF THE VERTEBRATA, PRO- GRESSIVE AND RETROGRESSIVE? BY E. D. COPE. ( Continued from page 148, February number.) Ill. THE LINE OF THE UROcHORDA. $ | ined ee ue evidence ieads us to. anticipate that the primitive Vertebrata possessed nothing representative of the vertebrate skeleton beyond a chorda dorsalis. Above this axis should lie the nervous chord, and below it the nutritive and repro- ductive systems and their appendages. Such a type we have in its _ simplest form in the Branchiostoma, the representative of the di- vision of the Acrania. In the animals of this division the mouth and anus have the usual vertebrate position, at opposite ends of the body-cavity. The Tunicata (formerly referred to the Mollusca) are now known to present a still more primitive type of Verte- brata, to which the name of Urochorda has been given. These curious, frequently sessile creatures, have a vertebrate structure during the larval stage, which they ultimately lose. They have the necessary chorda, and nervous axis with a brain, and a cere- ae bral eye. They have at this time a tail, and are free-swimming ; peculiarity which a few of them retain throughout life ape oe p- 147, 2d line from bottom, omit “ Batrach 1A lecture delivered before the Franklin se Jan. 16, 1884, (Erratum: on a”) 1885. } i Progressive and Retrogressive. 235 dicularia).! They differ from the Acrania in the positions of the extremities of the alimentary canal. The mouth is on the top of the anterior end of the animal, and is supposed by some anato- mists to represent an open extremity of the pineal gland of other Vertebrata; while the tract represented by this body, the third ventricle of the brain, and the pituitary body of the Crani- ata, are the remains of the primitive cesophagus of the Urochorda. The anus in the adult tunicates is either dorsal, or it opens into the body cavity, as in the young larve. In Appendicularia it is ventral (Gegenbaur). The history of the Tunicata cannot be traced by palzontolo- gists as yet, owing to the absence of hard parts in their structure. The evidence of embryology has, however, convinced phylogen- ists that the ancestors of this class resembled their larva, and that they have as a whole undergone a remarkable degeneracy. They have passed from an active, free life to a sessile one, and have lost the characters which pertain to the life of vertebrates generally. ; It was to have been anticipated, however, that all of these an- cestral Tunicata did not undergo this degenerative metamorphosis, for it is to such types that we must look for the ancestors of the other Vertebrata, the Acrania and the Craniata. And here palæ- ontology steps in and throws new light on the question. I have Pointed out briefly, on another page of the NATURALIST, that a second order must be added to the Urochorda, viz., the Antiar- cha, in which the anus presents the same position as in the Acrania, at the posterior end of the body, while an orifice of the upper surface represents the mouth of the Tunicata. To this order is to be referred the family of the Pterichthyidz, of which the typical genus, Pterichthys, is a well-known form of the Devonian period. This genus retained its tail, which was the cause, in con- nection with the presence of lateral fin-like appendages, of its having been supposed to be a fish, by Agassiz, Hugh Miller and . others. It is possible that the American Bothriolepis canadensis lost its tail, as in the majority of Urochorda. The tunicate which approaches nearest to the Antiarcha is the arctic Chelyosoma. From the Antiarcha to the Acrania and Craniata, then, the line is an ascending one. 1See Lankester on Degeneration, Nature Series, 1880. ? This (March) number, 1885, under “Geology and Palzontology.’ 236 On the Evolution of the Vertebrata, [ March, IV. Tue LINE OF THE PISCEs. The fishes form various series and subseries, and the tracing of all of them is not yet practicable owing to the deficiency in our knowledge of the earliest or ancestral forms. Thus the origins of the four subclasses, Holocephali, Dipnoi, Elasmobranchii and Hyopomata, are lost in the obscurity of the early Palzeozoic ages. = A comparison of the four subclasses just named shows that they are related in pairs. The Holocephali and Dipnoi have no distinct suspensory segment for the lower jaw, while the Elasmo- branchii and Hyopomata have such a separate element. The lat- ter therefore present one step in the direction of complication be- yond the former, but whether the one type is ‘descended from the other, or whether both came from a common ancestor or not, is unknown. If one type be derived from the other it is not certain which is ancestor, and whether the process has been one of ad- vance or retrogression. The fauna of the Permian epoch throws some light on the relations of these subclasses in other respects. The order of the Ichthyotomi,' while belonging technically to the Elasmobranchi, presents characters of both the Dipnoi and the Hyopomata. It is so near to the Dipnoi in the characters of the skull that nothing save the presence of a free suspensor of the lower jaw prevents its entering that subclass. It indicates that the one of these divisions is descended from the other, or both from a common division which may well be the group Ich- thyotomi itself. In case the Elasmobranchi have descended from the Ichthyotomi, they have undergone degeneracy, as the Ichthy- otomi have a higher degree of ossification and differentiation of the bones of the skull. If they descended from a purely carti- laginous type of Dipnoi, they have advanced, in the addition of the free hyomandibular. If the Dipnoi have descended from either division, they have retrograded, in the loss of the free hyo- - mandibular. As regards the Hyopomata, we have a clear advance ` over the other subclasses in the presence of the maxillary arch _and the opercular apparatus. _ Too little is known of the history of the subclasses, excepting _ the Hyopomata, for us to be able to say much of the direction of ~ the descent of their contained orders. On the sharks some light is shed by the discovery of the genus Chlamydoselachus Gar- See Palzeontological Bulletin No. 38, E.

This genus has more numerous branchial slits than all but two of the genera of existing sharks, and it differs from all but these two in having a more perfect articulation between the tooth-bearing bones and the cranium. Of the Hyopomata a much clearer history is accessible. It has three primary divisions or tribes which differ solely in the structure of the supports of the fins. In the first division, the Crossopterygia, the anterior limbs have numerous actinosts which are supported on a pedun- cle of axial bones. The posterior limbs are similar. In the sec- ond division, or Chondrostei (the sturgeons, etc.), the posterior limb remains the same, while the anterior limbs have undergone ` a great abbreviation in the loss of the axial bones and the reduc- tion of the number and length of the actinosts. In the third group, or Actinopteri,? both limbs have undergone reduction, the actinosts in the posterior fin being almost all atrophied, while those of the fore limb are much reduced in number. The phylogeny of these tribes is not easy to make out at pres- ent. The descent has been no doubt in the order named in time, but the starting point is yet uncertain. Thus the Chondrostei appear later in time than either of the other tribes, a history which probably only represents our ignorance. The characters of the genus Crossopholis Cope, from the American Eocene, strongly suggests that the existing forms have descended from scaled an- cestors. The Crossopterygian fore limb, with its arm-like axis, tells of the origin of the first limbed vertebrates, the Batrachia, whose skull-structure, however, only permits their derivation from the Dipnoi or Holocephali. As the former subclass has the Crossopterygian fin structure, we can safely regard them as the ancestors of the Batrachia, while the Crossopterygia are a side line from a similar type, probably the Ichthyotomi, because these have a free suspensor of the lower jaw. But of the structure of the fins of the Ichthyotomi unfortunately we know nothing. If this position be true, then the successive derivation of the Chon- drostei and the Hyopomata in one line is rendered probable. The modification of structure has consisted in the contraction of the supporting elements of the pectoral and ventral fins by the reduc- tion of their numbers and length. According to paleontological 1 Proceedings American Assoc. Adv. Sci., 1884. 3 Partly agrees with the Teleostei of Müller, but includes many of his Ganoidea. 238 On the Evolution of the Vertebrata, { March, history, however, the tribe with most contracted fins, Actinopteri, appeared in the Coal measures (Paleoniscide), or very soon after the Crossopterygia in the Devonian. The descent of the fishes in general has witnessed, then, a contraction of the limbs to a very small compass and their sub- stitution by a system of accessory radii. This has been an ever widening divergence from the type of the higher Vertebrata, and from this standpoint, and also a view of the “ loss of parts without complementary addition of other parts,” may be regarded asa process of degradation. Taking up the great division of the Actinopteri, which em- braces most of the species of living fishes, we can trace the direc- tion of descent largely by reference to their systematic relations when we have no fossils to guide us. The three subtribes adopted by Jordan represent three series of the true fishes which indicate lines of descent. The Holostei include the remainder of the old ganoids after the subtraction of ‘the Crossopterygia and the Chondrostei. They resemble these forms in the muscular bulbus arteriosus of the heart and in the chiasm of the Optic nerves. Both of these characters are com- plexities which the two other divisions do not possess, and which, as descendants coming later in time, must be regarded as inferior, and therefore to that extent degenerate. Of these divisions the Physostomi approach nearest the Holostei, and are indeed not distinctly definable without exceptions. The third division, or Physoclysti, shows a marked advance beyond the others in: (1) The obliteration of the primitive trachea, or ductus pneumaticus, which connects the swim-bladder and cesophagus; (2) the advance of the ventral fins from the abdomen forwards to the throat; (3) the separation of the parietal bones by the supraoccipital ; (4) the - presence of numerous spinous rays in the fins; and (5) the roughening of the edges of the scales, forming the ctenoid type. There are more or less numerous exceptions to all of these char- acters. The changes are all further divergences from the other vertebrate classes, or away from the general line of ascent of the vertebrate series taken as a whole. The end gained is specializa- _ tion, but whether the series can be called either distinctively pro- _ gressive or retrogressive is not so clear. The development of = osseous spines, rough scales and other weapons of defense, to- a gether with the generally superior energy and tone which prevail 1885.] Progressive and Retrogressive. 239 among the Physoclysti, characterize them as superior to the Physostomi, but their departure from the SEP line of the Vertebrata has another appearance. The descent of the Physoclystous fishes has probably been from Holostean ancestors, both with and without the intervention of Physostomous forms. This is indicated by increase in the number of actinosts in the fins of families which have pectoral ventral fins, as in the extinct genus Dorypterus} The Physostomi display three or four distinct lines of descent. The simplest type is represented by the order Isospondyli, and palzontology indicates clearly that this order is also the oldest, as it dates from the Trias at least. In one line the anterior dor- sal vertebrae have become complicated, and from an interlocking mass which is intimately connected with the sense of hearing. This series commences with the Characinide, passes through the Cyprinidz, and ends with the Siluride. The arrangements for audition constitute a superadded complication, and to these are added in the Siluroids defensive spines and armor. Some of this order, however, are distinctly degenerate, as the soft purblind Ageniosus, and the parasitic Stegophilus and Vandellia which are nearly blind, without weapons, and with greatly reduced fins. The next line (the Haplomi, pike, etc.) loses the przecoracoid arch and has the parietal bones separated, both characters of the Physoclysti. This group was apparently abundant during the Cretaceous period, and it may have given origin to many of the Physoclysti. Another line also loses the precoracoid, but in other respects diverges totally from the Physoclysti and all other Physostomi. This is the line of the eels. They next lose the connection be- tween the scapular arch and the skull, which is followed by the loss of the pectoral fin. The ventral fin went sooner. The pala- tine bones and teeth disappear, and the suspensor of the lower jaw grows longer and loses its symplectic element. The opercu- lar bones grow smaller, and some of them disappear. The _ ossification of most of the hyoid elements disappears, and some of their cartilaginous bases even vanish. These forms are the marine eels or Colocephali. The most extraordinary example of specialization and degeneracy is seen in the abyssal eels of the family Eurypharyngide. Here all the degenerate features above 1 See Proceeds Amer. Assoc Adv. Science, 1878, p. 297. 240 On the Evolution of the Vertebrata, [ March, mentioned are present in excess, and others are added, as the loss of ossification of a part of the skull, atmost total obliteration of the hyoid and scapular arches, and the semi-notochordal condi- tion of the vertebral column, etc. The Physoclysti nearest the Physostomi have abdominal ven- tral fins, and belong to several orders. It is such types as these that may be supposed to have been derived directly from Holos- tean ancestors, They appear in the Cretaceous period (Derceti- dz), along with the types that connect with the Physostomi (Haplomi). Intermediate forms between these and typical Phy- soclysti occur in the Eocene (Trichophanes, Erismatopterus), showing several lines of descent. The Dercetidæ belong appa- rently to the order Hemibranchi, while the Eocene genera named belong apparently to the Aphododiride, the immediate ancestor of the highest Physoclysti, the Percomorphi, The order Hemi- branchi is a series of much interest. Its members lose the mem- brane of their dorsal spinous fin (Gasterosteidæ), and then the fin itself (Fistularia, Pegasus). The branchial apparatus has under- gone, as in the eels, successive deössification (by retardation), and this in direct relation to the degree with which the body comes to be protected by bony shields, reaching the greatest defect in the Amphisilida. One more downward step is seen in the next suc- ceeding order of the Lophobranchii. The branchial hyoid appa- ratus is reduced to a few cartilaginous pieces and the branchial fringes are much reduced in size. In the Hippocampide the caudal fin disappears and the tail becomes a prehensile organ by the aid of which the species lead a sedentary life. The mouth is much contracted and becomes the anterior orifice of a sucto- ` rial tube. This is a second line of unmistakable degeneracy among true fishes. _ The Physoclysti with pectoral ventral fins present us with per- haps ten important ordinal or subordinal divisions. Until the palzontology of this series is better known, we shall have diffi- culty in constructing phylogenies. Some of the lines may, how- ever, be made out. The accompanying diagram will assist in un- derstanding them. _ The Anacanthini present a general weakening of the organiza- tion in the less firmness of the osseous tissue and the frequent ~ reduction in the size and character of the fins. The caudal ver- ~ tebree are of the protocercal type. As this group does not appear 1885.] Progressive and Retrogressive. 241 early in geological time, and as it is largely represented now in the abyssal ocean fauna, there is every reason to regard it asa degenerate type.

This cannot be called a degenerate line, although the fin-rays are soft. The Heterosomata (flounders) VoL. XIX.—=NO. III, 16 242 On the Evolution of the Vertebrata, [ March, found it convenient to lie on one side, a habit which would appear to result from a want of motive energy. The fins are very ineff- cient organs of movement in them, and they are certainly no rivals for swift-swimming fishes in the struggle for existence, ex- cepting as they conceal themselves. In order to see the better’ while unseen, the inferior eye has turned inwards, z. e., upwards, and finally has penetrated to the superior surface, so that both eyes are on one side. This peculiarity would be incredible if we did not know of its existence, and is an illustration of the extra- ordinary powers of accommodation possessed by nature. The Heterosomata can only be considered a degenerate group. The double bony floor of the skull of the Distegous percomorph fishes is a complication which places them at the summit of the line of true fishes. At the summit of this division must be placed the Pharyngognathi, which fill an important role in the economy of the tropical seas, and the fresh waters of the Southern hemi- sphere. By means of their powerful grinding pharyngeal appara- tus they can reduce vegetable and animal food inaccessible to other fishes. The result is seen in their multifarious species and innumerable individuals decked in gorgeous colors, and often reaching considerable size. This is the royal order of fishes, and there is no reason why they should not continue to increase in importance in the present fauna. Very different is the line of the Plectognathi. The probable ancestors of this division, the Epilasmia (Chztodontide, etc.), are also abundant in the tropical seas, and are among the most bril- liantly colored of fishes. One of their peculiarities is segn in a shortening of the brain-case and prolongation of the jaws down- wards and forwards. The utility of this arrangement is probably to enable them to procure their food from the holes and cavities _ of the coral reefs among which they dwell. In some of the gen- era the muzzle has become tubular (Chelmo), and is actually used as a blow-gun by which insects are secured by shooting them with drops of water. This shortening of the basicranial axis has produced a corresponding abbreviation of the hyoid apparatus. The superior pharyngeal bones are so crowded as to have become a series of vertical plates like the leaves of a book. These char- acters are further developed in the Plectognathi. The brain-case i is very small, the face is very elongate, and the mouth is much eae The bones surrounding it in each jaw are codssified. i 1885.] Progressive and Retrogressive. 243 The axial elements (femora) of the posterior fins unite together, become very. elongate and lose the natatory portion. In one group (Orthagoriscidz) the posterior part of the vertebral col- umn is lost and the caudal fin is a nearly useless rudiment. In ‘the Ostraciontide (which may have had a different origin as the pharyngeal bones are not contracted), the natatory powers are much reduced, and the body is enclosed in an osseous carapace so as to be capable of very little movement. The entire order is deficient in osseous tissue, the bones being thin and weak. -Itis a marked case of degeneracy. There are several evident instances of sporadic degeneracy in other orders. One of these is the case of the family of the Icos- teidz, fishes from deep waters off the coast of California. Al- though members of the Percomorphi, the skeleton in the two genera Icosteus and Icichthys is unossified, and is perfectly flexi- ble. Approximations to this state of things are seen in the para- sitic genus Cyclopterus, and in the ribbon fishes, Trachypteride. Thus nearly all the main lines of the Physoclysti are degen- erate; the exceptions are those that terminate in the Scombride | (mackerel), Serranida, and Scaridz (Pharyngognathi), V. THE LINE OF THE BATRACHIA. We know Batrachia first in the coal measures. They reach a great development in the Permian epoch, and are represented by large species in the Triassic period. From that time they dimin- ish in numbers, and at the present day form an insignificant part of the vertebrate fauna of the earth. The history of their suc- cession is told by a table of classification, such as I give below: I. Supraoccipital, intercalary and supratemporal bones present. Propodial n .

Ganocephala® An examination of the above tables shows that there has been in the history of the Batrachian class a reduction in the number of the elements composing the skull, both by loss and by fusion with each other. It also shows that the vertebrae have passed from a notochordal state with segmented centra, to biconcave centra, and finally to ball and socket centra, with a ‘great reduc- tion of the caudal series. It is also the fact that the earlier forms (those of the Permian epoch) show the most mammalian charac- ters of the tarsus and of the pelvis The later forms, the sala- manders, show a more generalized form of carpus and tarsus and of pelvis also. In the latest forms, the Anura, the carpus and- tarsus are reduced through loss of parts, except that the astraga- _ lus and calcaneum are phenomenally elongate. We have then, in the Batrachian series, a somewhat mixed kind of change ; but it principally consists of concentration and consolidation of parts. The question as to whether this process is one of progression Or 1 Probably includes the Gymnophiona, of Eryops is much like that of the Theromorph reptiles. See heirs Amer. — Soc., 1884, p. 38, eS PIEN a ee ee ee ae : bore * 1885.] Progressive and Retrogressive, 245 retrogression may be answered as follows: If degeneracy con- sists in “the loss of parts without complementary addition of other parts,” then the Batrachian line is a degenerate line. This is only partly true of the vertebral column, which presents the most primitive characters in the early, Permian, genera (Rhachi- tomi). If departure from the nearest approximation to the Mam- malia is degeneracy, then the changes in this class come under that head. The carpus, tarsus and scapular and pelvic arches of the Rachitomi are more mammalian than are those of any of their successors, : There are several groups which, show especial marks of degen- eracy. Such are the reduced maxillary bones and persistent gills of the Proteida; the absence of the maxillary bones and the presence of gills in the Trachystomata; the loss of a pair of legs and feebleness of the remaining pair in the sirens; and the extreme reduction of the limbs in Amphiuma. Such I must also — regard, with Lankester, the persistent branchiz of the Siredons. I may add that in the brain of the Proteid Necturus the hemi- spheres are relatively larger than in the Anura, which are at the end of the line. It must be concluded, then, that in many respects, the Batrachia have undergone degeneracy with the passage of time. VI. Tue REPTILIAN LINE. As in the case of the Batrachia, the easiest way of obtaining a general view of the history of this class is by throwing their principal structural characters into a tabular form. As in the case of that class I commence with the oldest forms and end with the latest in the order of time, which, as usual, corresponds with the order of structure. I except from this the first order, the Ichthyopterygia, which we do not know prior to the Triassic period 2 A. Extremities not differentiated in form beyond proximal segment. I.

An inspection ofthe characters of these ten orders, and their con- sideration in connection with their geological history will givea defi- nite idea as to the character of their evolution. The history of the class, and theréfore the discussion of the question, is limited in time to the period which has elapsed since the Permian epoch inclusive, for it is then that the Reptilia enter the field of our knowledge. During this period but one order of reptiles inhabited the earth, so far as now known, that of the Theromorpha. The important character and role of this type may be inferred from the fact that they are structurally nearer to both the Batrachia and the Mam- malia than any other, but present characters which render it prob- : res that all the other reptiles, with possibly the exception of the 1 This definition includes the Crocodilia in the Dinosauria, as it is absolutely con-, nected with the typical Dinosaurs by the Opisthoccela (Sauropoda Marsh). ?Episternum present.

The species of Cyclus may be referred to a distinct family group for which we propose the name Cyclide. Dipeltis diplodiscus, gen. et sp. nov.—This name is proposed for a singular form which is not satisfactorily preserved, so that its exact relations are not readily determinable, though it will be recognizable as a Cyclus-like form. The body is suborbicular, flat- tened, disk-like, sloping regularly and gradually from the median area to the edge; it is divided into two portions; the larger one to be regarded as anterior or the cephalic shield, and the other as posterior, constituting the abdomen (urosome). The edge of the body is very slightly emarginate, not broadly so as in ree nor is the body distinctly trilobate as in the Limulidz, thoug _ with the succeeding 294 General Notes. [ March, unfortunately the median area of the cephalic shield is wanting. The integument is rather thin, showing no traces of segments; its surface may have had a few scattered small tubercles, at least there are slight indications of them. The surface is smooth and shining. The cephalic shield is nearly twice as broad as long; the pos- terior lateral angle is well-rounded, with no sign of a lateral spine; in front the edge was probably obtusely rounded; the surface is slightly convex, the disk being low and flat; the hind edge of the shield is moderately concave, the limits between it and the urosome being clearly indicated by a slight, but distinct, regular curvilinear suture. The urosome is about three-fourths as long as, but equal in width to the cephalic shield. The front edge is somewhat arcu- ate, so that the projecting anterior-lateral angle is directed a little forward, and is quite free from the lateral angle of the cephalic shield, which turns away anteriorly from it, leaving a triangular space between the sides of the two regions. Posterior edge of the urosome regularly rounded, and with slight margin. No traces of a caudal lobe or spine.

Silurian —At a recent meeting of the Paris Academy of Sciences, M. Daubrée called attention to the discovery, by M. Buneau, in coal belonging to the Lower Carboniferous, of tne re- mains of a species of Equisetum, a genus not previously known to occur below the middle coal measures, The remains of the stems occurred with various Diplothemema and Calymmatotheca, which proved the stage to be the upper grauwacke. The species has been named Æ. antiquum. A. Milne-Edwards announced the discovery in the Silurian of Scotland, of a new scorpion abso- lutely identical with that which had previously been found by M. Lindstrom in the upper Silurian of the island of Gothland. The only difference is one of sex, the one being male, and the other female. M. Brongniart recently called the attention of the Paris Academy of Sciences to a fragment of rock belonging to the middle Silurian, and containing: the impression of an insect’s wing, that of a cockroach, differing from all other blattidian wings, recent or fossil, in the length of the anal nerve, and the width of the axillary field. M. Brongniart called this ancestor ot the cockroaches Paleoblattina penvillei,and stated that it was more ancient than the scorpion found by M. Lindstrom, since it belonged to the middle instead of the upper Silurian.

The dental formule of Pleuras- pidotherium and Phalangista, are practically identical. The bones of the face are remarkable for the development of the intermaxil- laries and nasals, and for the almost complete ossification of the palatine vault. The lower jaw has a broad commissure, as in Pachynolophus, and a special development of the posterior branch recalls Phalangista, but is not inclined inwards.——M. F.

The same writer describes the shells of the fresh- water and brackish group of Aix in Lower Languedoc, Pro- vence, and Dauphine, 92 species in all, 11 of which belong to Potamides, 11 to Striatella, 3 to Melania proper, 3 to Ripa, 14 to M.

Quaternary—A. Mehring (Kosmos, 1883) gives faunistic proofs of the former glaciation of North Germany. Against the “drift theory,” he urges that the greater portion of the low-lying parts of North Germany are either entirely free from animal re- mains, or enclose only land and fresh-water forms, which could not have been the case had a diluvial sea existed. Even the find- ing of marine animal remains in certain spots can be explained by position from southward moving glaciers, The nature of the deposits and other characters shows that the arctic fauna, the re- mains of which are found, had its home in the surrounding region.

Klein, Krocke and certain other German mineralogists, on the contrary, maintained that the optical peculiarities were produced, not by twinning but by a molecular disturbance due to an internal ten- sion caused by the irregular growth of the crystal} Klein had even succeeded in proving that the apparent twinning lines—the boundary between the areas of different optical orientation— could be made to move by raising the temperature,’ and the inter- pretation put by the same writer on the interesting observation of Mallard is very important, as offering a possible means of reconciling the different views which have hitherto existed re- garding these anomalous optical phenomena. Klein suggests that the fact that boracite becomes isotropic above 265° C., proves that this substance is dimorphous, crystallizing in the regular system above, and in some other, probably the orthorhombic, be- low this temperature’ The crystals must therefore have been formed at a temperature above 265° C., and hence possess geo- metrically the regular shape; their internal condition is due to the effort on the part of the molecules to rearrange themselves in accordance with the altered conditions, which is strong enough to produce a profound optical disturbance, but is not able to pull to pieces the crystalline form. Boracite crystals at ordinary tem- peratures are, in fact, a kind of paramorph, composed of optically orthorhombic portions enclosed in the regular framework in which the substance originally, at a higher temperature, crys- tallized. Still more recently Klein* has shown that leucite becomes iso- tropic at high temperatures, and Merian’ obtained a similar result for tridymite ; thus it seems very probable that many other sub- stances, like garnet, analcite, perofskite, senarmontite, etc., which show optical properties in no accord with their external form may be satisfactorily explained by the assumption that they are dimor- phous. _ Another class of substances like potassium npea leadhillite, aragonite, etc., whose optical properties at ordinary temperatures ite tn perfect accord with their crystalline form, have been shown capable of transference by increase of temperature to a state where their optical properties have a higher grade of symmetry, and consequently are no longer what the form would require, ¢. g., 1 Neues Jahrbuch fiir Min., etc., 1881, 1, pp. 255 and 256. 216. p. 239, et seq. 3 Neues Jahrbuch fiir Min., etc., 1884, I, p. 239. 74. ref. pp. 185 and 186. 4 Nachrichten d.

MINERAL SynTHEsIS.—Nearly everything heretofore done in the way of artificially reproducing natural minerals and their as- sociations in rocks has been produced in France (vid. NATURALIST, July, 1883, p. 780). Here, however, the results attained have been very interesting and important, and it is to be noticed with pleasure that the broad field which the researches of the French investigators have shown to be so fruitful is beginning to be successfully cultivated in Germany. Professor Doelter, of Graz, commenced, in connection with his colleague, Dr. Hussak, by studying the effects produced on various silicates by subjecting them to the action of different molten rocks.’ Augite yielded but small results, while hornblende was partially dissolved and changed to an aggregate of opaque grains and microlites of augite, as is often. observed in many volcanic rocks. Mica, gar- net, olivine, quartz, feldspar, zircon and cordierite were treated in same manner with different results, which cannot here be enumerated in detail. when melted and again allowed slowly to cool, produced meionite, melilite, anorthite, lime-olivine, lime-nepheline, hematite and spi- nell, together with more or less amorphous matter, but no trace of the original minerals ever appeared. The fusion of mixtures of the substances entering into the composition of garnet yielded no better results. It would therefore appear that something more than simple dry fusion is necessary to produce these two minerals. Doelter has still more recently busied himself with synthetical experiments on minerals of the pyroxene and nepheline groups. The lime and potash so often observed in the latter are probably isomorphous mixtures, since small amounts of Ca Al, Si, Os and K, Al, Sig Os, when melted with the typical nepheline molecule, Na, Al, Si, O; gave homogeneous crystalline masses having all e properties of nepheline. In regard to the aluminous pyrox- enes, Rammelsberg holds that the Al, O, and Fe, O, are present Klein: Nachrichten d. Kön. Ges. d.

An optical examination of a series of carefully analyzed natural pyroxenes also yielded Doelter interesting results regarding the particular constituents which caused an increase in the size of the extinction angle on the clinopinacoid? Wiik? attributed this to the amount of FeO present (vid. NATURALIST, Oct., 1882, p. 836), but Doelter considers it rather dependent on the proportions of the molecules Fe Ca SiO; or R R, SiO, which the pyroxene contains, in this following the suggestion recently made by Fr. Herwig in his article on the optical orientation of the pyroxene- hornblende minerals. In this connection may be mentioned among the synthetical work lately produced in France, the artificial production of rho- donite, tephroite, hausmanite, barite, celestite and anhydrite by Alex.

The flower and peduncle of Anemone hepatica were 4™™ long; of Sanguinaria canadensis, 3°™' of Arisema dracontium, mm. The flowers of Trillium grandiflorum was 8™™ long. The hibernaculum of Aralia quinquefolia in all the plants ex- amined was composed of three scales, the innermost entirely sheathing next year’s flowering stalk and also a small bud. The latter is in the axil of the scale, and is destined to produce the flowering stalk two years hence. The leaf of the flower stalk which is opposite to the last scale is always the largest. When the leaves occur in whorls of fours, as was frequent in the speci- mens at hand, the relative stage of development of the leaves and their position suggested a contracted spiral of leaves rather than a single and sessile twice-compound leaf, as suggested by Gray (Manual, p. 199). The flowers could easily be determined, the outermost flowers being developed the most. In view of the early development in bud of the flowers of spring plants, need their early appearance in spring be surprising? Aralia guinque- folia flowers in July, and in August of the same year shows ripened berries and the parts of next year’s plant!

Foerste, Granville, Ohio. ; l A SIGNIFICANT Discovery.—In a recent number of Nature, Mr. W. T. Thiselton Dyer calls attention to a most interesting and significant discovery in the development of certain ferns. Some months ago Mr. E. T. Druery observed in Asplenium filix- fæmina, var. clarissima, that the sporangia “ did: not follow their ordinary course of development, but assuming a more vegetative character, developed more or less well-defined prothallia,” which ultimately bore antheridia and archegonia. “From these adven- titious prothallia the production of seedling ferns has been ob- served to take place in a perfectly normal way.” The prothallia were subsequently observed by Mr. F. O. Bower to be furnished with root-hairs The last-named observer was so fortunate as to discover a still more remarkable development upon Polystichum ( Aspidium) an- _ gulare, var. pulcherrima. Here the apex of the pinnules grew ou into an irregular prothallium, upon which antheridia and arche- gonia were clearly made out. : It is a genuine pleasure to note such discoveries, for they are just what we have reason to expect. If, now, so great a change in the ordinary course of development as this is, can take place so suddenly, does it not, to say the least, argue in favor ot the _ possibility of similar changes in the past having given rise to the -~ Phanerogams? What essential difference is there between these _ aposporous ferns and the lower phanerogams? The most remark- 1885.] Botany, 303 able feature about the discovery is the fact that it pertains to pteridophytes of as low a type as the ferns of the Polypodiacee. If it occurs there, may we not look for it confidently in the Lyco- pods, and especially in the Selaginella, It may be worth giving a good deal of attention to a careful examination of the green- house grown plants of the various species of Selaginella. Apo- spory in these would possess many interesting features. Who will search for it ? Tue History or Discovery IN Ferns.—Mr. W. T. T.

De Bary’s COMPARATIVE ANATOMY OF VEGETATIVE ORGANS.— Between seven and eight years ago there appeared a most valuable contribution to the literature of histological botany from the pen of the great Strassburg professor. In its German form it has been familiar to workers in botanical laboratories, and has been of great service. Now we have an English translation by F. O. Bower and D. H. Scott, which has been brought out under the title of Comparative Anatomy of the vegetative organs of the Phanerogams and Ferns, by the Clarendon Press in England, and placed before the American public by the New York house of Macmillan & Co. In its English form it consists of about 675 octavo pages, having the general appearance both in type, illus- trations, r and binding of the well-known English editions of Sachs’ Text Book. ae : For the benefit of those who are not familiar with the work, we give here its general contents: Part I.

Journat or Mycotocy.—There has been a feeling for a long while that this country should have a journal of mycology in which should be published all the descriptions of new species of fungi. The matter was talked over somewhat in Philadelphia last September by members of the Botanical Club of the A. A. A. S., and it has now so far taken form as to result in the issuance of a prospectus. It is to be “edited by J. B. Ellis, Newfield, N. J., and W. A. Kellerman, Manhattan, Kan. It will be issued about the 1st of each month, contain from twelve to fifteen pages, and be ed exclusively to mycological botany, special attention be- ing given to the North American Fungi. It will contain descrip- tions, of new species as they appear from time to time; another leading feature will be the publication of monographs of different pn with descriptions of ali the North American species known—thns making, in fact, a manual of our fungi. A full account will also be given of all the current literature pertaining to this subject.” We bespeak for this much-needed journal a liberal patronage. _ The business management will be in the hands of Dr. Kellerman, to whom subscriptions ($1) should be sent. = Boranicat Notes——Friedlender & Son, the well known book- -sellers of Berlin, have just issued three very valuable catalogues of __ books treating of cryptogamic plants.

Notes on THE Mounps OF THE OcciDENT ANT.—The mounds built by the Pogonomyrmex occidentalis can hardly fail to attract the attention of any observing traveler. neatly smoothed bare spot, from three to five feet in diame- ter is found in the grass and in its center is a mound of quite sym- metrical form. This mound is frequently covered entirely with Coarse sand ,or fine gravel, even when the surrounding surface shows little of this material. ; It would seem, at first, that the ants, guided by some instinct, selected the material which would best secure their structure from the wind and the rain. During the past season the writer has found opportunity to test this point. A little watching showed that the excavation below the surface and the building of the mound are carried on by two different sets of workers, one continually bringing out particles from within and dropping them upon the court or bare space around the mound, the other picking up particles from the surface of the court and depositing them upon the mound. The coarse- ness of the material seems to'be determined by the desire of a worker to find as large a particle as he can conveniently carry. For instance, when, as in the case observed, the crust of the ground was broken by the tramping of a horse, medium sized pieces were deposited upon a mound, but none of the smallest and _. Of course none of the largest, as ants have not learned to wor otherwise than individually. When particles of broken glass were scattered upon a court they were quickly found and in spite of their angular and polished surface were soon carried and dropped upon the mound.

NOTES ON THE BREEDING HABITS OF THE LIBELLULIDÆ.— The following observations, though incomplete, are offered because there is no prospect that the writer can pursue the subject farther, at least not for some time. In the month of July, ’82, while camping near Bear creek, Da- kota, on a bright, breezy day, his attention was attracted to num- bers of dragon-flies hovering over the surface of the water. Many of them were in the usual position when pairing. The male holding the female by the back of the head with his claspers. From the bottom of a deep clear pool various water-plants came to the surface, and as the water was rippled by the breeze, their tops were occasionally thrown out of the water. Many dragon-flies were noticed hovering about, especially around the tops of these plants; the female evidently endeavoring to gain a footing upon them. In a short time one was suc- cessful and immediately folded her wings backward and com- menced crawling down the stem into the water. The male meanwhile was forced to let go to prevent his being dragged into the water. I could see the females until they were about a foot below the surface of the water but of course could not trace them to the bottom which must have been at a depth of from three to five feet. They seemed the more conspicuous because of the quan- tity of air which adhered to their abdomen and wings. After losing his companion the male hovered about, resting occasionally upon the grass at the border of the pool, and evidently watching for the return of the female. I was unable to determine, very satisfactorily, the length of time which the female remained below the surface, but after the first after seizing her towed her to shore, being apparently unable to lift her from the water. A male falling accidentally upon the water was not similarly rescued. The water was more or less infested with fish and it seems:not i 1885.] Entomology. 307 serving were not at hand, but it resembles quite closely another species which has been determined by Dr. Hagen as Lestes ungui- culata. The latter species, at another locality, was found deposit- ing eggs in the stems of bulrushes and cat-tails, the male accom- panying the female in a position similar to that in the first species named, The female saws a hole through the skin with her ovi- positor and deposits the egg in the pith. Similar localities have been diligently watched by the writer during the past two seasons, but it has not been his privilege again to see the dragon-flies go below the surfacc of the water. The laying of eggs in the stems of bulrushes is a very common sight about the marshy ponds and streams of Dakota. The different stages or positions in the process of copulation in the dragon-flies are very interesting and sometimes puzzling, but as a general rule they seem to be as follows :—at least it is so with the genus Lestes. First, the male seizes the female by the back of the head and flies some time with her in this position before the second stage is reached, in which the male, still holding the female, curves his abdomen and charges the seminal sac, then re- sumes the first position. The female seizes the abdomen of the male with her feet and brings the tip of her abdomen forward and receives the seminal fluid from its receptacle From the third the fourth is readily reached by the female withdrawing her abdomen and letting go with her feet or not as the case may be. In the species of Lestes before referred to the fourth position corresponds to the first. It seems not improbable that after laying a number of eggs the female may return to the second position and become fer- tilized for a second brood. The length of time which is occupied evidently varies considerably. In some cases I have observed, the males and females united during their rest at night. Another curious habit observed, especially in a large olive-green species of Æschna, is this: while flying at full speed the insect dashes flat upon the surface of the water in a pond and, apparently by the rebound, recovers its position in the air, This may serve the purpose of a bath, clearing the wings of dust, or possibly of par- asites.— ¥ E.

[ March, tinguishable; beneath, the segment is distinct on the sides, but obsolete in the middle. In the larval butterflies the ninth segment is rather more distinct than in the Sphinges, but it is short; the tenth segment is as in all caterpillars represented by the supra-anal plate and anal legs. In the A‘gerians, Zygænidæ and Bombycidz, the latter especi- ally, the ninth segment is very distinct. In Halesidota the ninth segment is quite long, forming an entire segment, with its own set of hair-bearing warts, the urite, or ventral surface is- quite dis- tinct from the infra-anal plate or tenth urite. In Datana the ninth segment is longer than the supra-anal plate; in Lochmaus tessella with its long anal filaments, the homologues of the anal feet, the ninth segment is distinct from the tenth; in an allied Notodon- tian with elongated anal legs, the ninth segment is unusually long and distinct. In Teea polyphemus there are ten abdominal seg- ments, counting the supra-anal plate and anal legs as the tenth ; in Hyperchiria io and Clisiocampa the ninth is distinct from the tenth segment In Limacodes scapha and P. pithecium there are no traces of legs; the number of abdominal segments appears to be ten. In the Noctuidae the ninth segment is distinct, with a series of -verticils above and a well marked ventral portion or urite. In the geometers the ninth segment is distinct above but below merged into the infra-anal plate. In the Pyralid caterpillars, as well as the Tortricids and Tineids, the ninth segment is longer and more distinct than in the higher families. Although the indications are slight, yet the Bombycidz, as we have previously remarked, seem to be the oldest, most generalized group of Lepidoptera, and it is a question whether the Pyralids, Tortricids and Tineids are not degenerate forms which have de- scended fron the Noctuidz and ultimately from the Bombycide ; there are indications that the Noctuide have descended from the. geometers, since the young of the Plusiæ and Catocale, &c., have three pairs of abdominal legs, being semi-loopers when hatched, and afterwards acquiring the additional pair of legs. At any rate the primitive caterpillar had ten pairs of abdominal legs. _ it will be remembered that the saw-fly larvae (Lophyrus) have eight pairs of abdominal legs, while the embryo honey-bee has tenpairs of temporary abdominal appendages.—A.

Sograff in the Moscow Transactions. In the Bulletin of the Brooklyn Ento- mological Society, Nov., 1884, Mr. G. Gabe claims that Riyssa lunator is not a true ichneumon, but a true wood-feeder. The breeding habits are described, and the mode of oviposition. Dur- ing the process the long ovipositor is bent, passed between the posterior legs, the abdomen is elevated almost to a right angle with the thorax, and the ovipositor, guided by the anterior tarsi is forced with a ramming motion into the wood to the depth of from two orthree inches. He has watched many females ovipositing and has cut off the ovipositor when ready to be withdrawn, and in no instance has he found a larva of any kind anywhere near the point reached by the borer, and where the egg was deposited. Messrs. Hulst and Weeks stated that they had reached the same conclusion from independent observation. During the past winter Prof. Packard has given a series of talks or lectures to the Providence Entomological Society on the structure and habits of insects, in order to aid those members whose time does not per- mit them to obtain a general knowledge of the subject.

[ March, posed to the light, only lost one specimen, and that on the rooth ay. Dr, Graff concludes that the Algz or pseudochlorophyll bodies of Hydra have no significance as means of nutrition; the fact that all the specimens in filtered water died by the 87th day seems to show that the Hydra died from the want of animal food, and that the green bodies do not serve as such, as Brandt supposes. The most unexpected and perhaps the most remarkable fact is that whether the Hydra were exposed to the light or placed in the dark, they in all cases retained their green color through life. Dr, Graff has lately been able to make some observations on the Mesostoma viridatum, three out of five examples of which were richly provided with chlorophyll-corpuscles; these varied very considerably in size, and no nucleus was to be detected in the smaller specimens; starch granules of proportionate size to that of the chlorophyll-bodies were found in them. The larger green bodies were arranged in closed groups, and the smaller examples lay between the groups; most of the bodies were rounded, but a few of the larger were oval.— Fourn. Royal Micro- scopizal Society, Dec., 1884. A FREE-SwimMinG Sporocyst.—The egg in the digenetic Tre- matode worms, as is well known, does not at once give rise to the adult Distome, but to a brood-sac which produces directly or . indirectly in its interior a greater or less number of larval Dis- tomes. The brood-sacs live parasitically within mollusks, and tailed larvæ or Cercariz, but the tail may be very short as in micrura Filippi, or entirely absent as in C. globipora Ercolani, again the cylindrical sporocysts produce Cercariz with furcate tails like C. furcata, and the remarkable Bucephalus-larve are _ produced in branched tubular sporocysts. _The object of the present note is to indicate the existence of a hitherto unknown form of sporocyst, one specimen of which I _ observed recently swimming very actively in an aquarium con- ~ taining a few water plants’ and fresh-water mollusks. In form and _ Size it recalls the larger Cercarie with forked tails, and contains - _ a single tailless Cercaria or istome. In accordance with its free life, the muscular system is much better developed than 1885.] Zoölogy, 311 usual, and the same is true of the water-vascular system. Of especial interest are tactile papilla, which beset the surface, and which obviously enable the sporocyst to find the definitive host for its contained larva. These papillae are somewhat more com- plicated than the similar structures described by Fischer from the neighborhood of the cirrus-pouch of Opisthotrema cochleare (Zeit. wiss. Zool. XL, 12). Ina future paper I propose to give a full account of the structure of the sporocyst and its contained larva. It would be premature to attach any specific name to the Dis- tome, as it may turn out to be a well-known form, but I am at present unable to offer any suggestion as to its “whence” or “whither.” I examined the mollusks in the aquarium for other specimens in vain, and, in the hope of obtaining others for infec- tion experiments, hardened and sectioned the only one I had se- cured, Professor Leuckart, to whom I communicated the substance of the above, writes: “ Your observation is certainly calculated to astonish helminthologists. I doubt whether the creature is really free-living, but believe that, in place of the Cercaria, it represents only the swarm-phase of the parasite. An entirely free-living sporocyst, without intestine, would hardly find the conditions necessary for a complete existence. It probably lives parasiti- cally within a mollusk, and wanders out after development of the contained larva, in order to seek a suitable host for the latter. Perhaps it may attach itself to the host by the flat lobes of the forked tail, and then discharge the larva imprisoned within it.”— R. Ramsay Wright, University College, Toronto, Fan. 12, 1885. STRUCTURE oF EcuHINopERMS.—C. F. Jickeli has a preliminary note in which he states that he has made experiments confirma- tory of the doctrine of Carpenter as to the nervous system of Comatula. He finds that a -single arm gives no response when the ambulacral groove is touched with a needle or stimulated by an electric current, but that the moment the needle touches the point at which the axial cord lies the arm is strongly flexed, and the pinnulæ more actively. A single cirrus when stimulated appears to be thrown into a tetanic condition. Many of the author’s experiments are in exact agreement with those of Car- penter. After the removal of the visceral mass irritation of the capsule produces a synchronous contraction of all the arms. Ifa few drops of osmic or acetic acid are put in the water, the i njured animal. bY : observations of P. H. Carpenter that nerve-branches pass into the dorsal and the ventral muscles is confirmed. A series of sec- tions shows that the ambulacral nerve diminishes in extent as it approaches the intestine, and finally disappears. Attention is 312 General Notes. [ March, drawn to the fact that Gotte describes the epithelium of the so- called ambulacral groove of Comatula as being endodermal in origin. A third nerve-center is described as being present in the con- nective tissue, and as forming a pentagonal cord around the mouth. The lateral cords are connected by branches with one another at the angles of the pentagon, and they extend along the water-vascular system; each of these cords gives off lateral branches at regular distances, and these innervate the water-vas- cular system, and the papillae of the tentacles. Other well-de- veloped branches are also given off to the ventral integument ot the body, where they.are lost in a fine nervous plexus. Lud- wig’s view of the glandular character of the tentacles appears to be incorrect. They have 3-4 sensory hairs and a centrally-placed slowly-moving flagellum. From these observations it would fol- low that the tentacular papilla are complicated sensory organs.— Fourn.

As a rule, however, the species having the wider geographical distribution are those from the shallower depths. Another exception to this rule is the genus Catenicella, rich in species, and almost confined to shallow Australian seas. Mollusca— Nature, in reviewing Dr. R. Bergh’s report upon the Nudibranchs collected by the Challenger, remarks that few shallow water dredgings were made during the cruise, and thus it is not strange that only twenty-five species were found. The majority of them are Phylliroide and A®olidiadz, and are pela- gic; some are littoral,as Fanclus australis, of which a single spe- cimen was taken in the Arafura sea. Another, Cuthonella abyssi- cola, was taken by the trawl in Farce channel at 608 fathoms. Some new Tritoniade and Dorididæ are described, and among the latter the most interesting is Bathydoris abyssorum. The body of this species is semiglobular, as in the genus Kalinga of Alden and Hancock, and it resembles this genus also in having branchie composed of several separate branchial tufts, as well as in the presence of soft conical papillz onthe back. It has no frontal appendage, and a very slightly pronounced dorsal margin, and seems to connect the Doridide with the Tritoniade. The only specimen was taken in 2425 fathoms in the middle of the Pacific. The body of the living animal was gelatinous and transparent, the foot dark purple, the tentacles brown, and the gills and other ex- ternal organs orange. One specimen only of the Onchidiade, O. melanopneumon, was taken in shallow water at Kandara, Fiji. Dr. Bergh believes these animals to have no relation to the Nudi- branchs,——Mr. J. R: Davis (Nature, Jan. 1), assert that limpets have a settled home, for they occupy scars on the rock, often sunk to a considerable depth. He marked and watched specimens to prove this, and found that, though a marked limpet might move about three feet from its scar in any direction, in search of food, it always found its way back. A limpet always returns be- fore the rising tide reaches it, and roosts with its snout pointing in the same direction: Mr. Davis asks what sense is used? Th eyes of a limpet, mere sensitive cups, can at most distinguish dif- ferent degrees of light intensity ; the examples deprived of their tentacles found-their way back, and repeated washing of the track with sea-water in order to destroy scent did not prevent the lim- been found upon the stalks of fossil Pentacrini. Dr. von Graft requests any palzontologist having crinoids under his care to ex- amine the specimens, and, if he should notice little pustules at the base of the pinnules, to communicate with him. Graff's class Stelechopoda embraces the Tardigrades, Linguatulids and My- zostomes. The forms before known were characterized by the 314 General Notes. [ March, peculiar radial arrangement of the organs of the body, but among the sixty-seven species here described are many which are without this radial arrangement, while in Stelechopus not even the muscular septa and parapodal muscles are convergent. This fact strengthens Dr. von Graff’s previous idea that the radial sym- metry was an adaptive change due to fixation. Several forms are entirely without suckers, while in M. ca/ycotyle the suckers are stalked. The Myzostomes are dicecious, but the sexes unlike. When inhabiting the same cyst the female is usually from fifty to a hundred times larger than the male." Crustacea.—Dr. P. P. C. Hoek found complemental males in nineteen out of the forty-one new species of Scalpellum gathered by the Challenger Expedition. Some of those complementary males do not show a division of the body into capitulum and peduncle ; a second section still without such division has rudi- mentary valves; a third has valves, capitulum and peduncle. Darwin's “ true ovaria” are believed to be pancreatic glands. Birds—Dr. W. Buller (Trans. N. Z. Institute, 1883) furnishes notes on some rare New Zealand birds. Sceloglaux albifacies, the laughing owl, has been found in deep fissures of the limestone rocks at Albury, near Timaru. Examples were procured by a process of smoking-out. In this species the male is the larger bird, and has a harsher cry than its mate. The four captured by Mr. Smith became quite tame, and in matters of food showed a decided preference for young rats, though they would eat mutton, beetles, lizards and mice. Their call on waking up at nightfall was “ precisely the same as two men cooeying to each other from a distance.” (The cry known as coo-ey is the call- note of Australasian settlers.) The rock-crannies in which they live by day and build their nests are dry, narrow at the entrance, and often five or six yards deep. They become almost naked while molting, and in this state two of Mr. Smith’s birds were stung to death by a swarm of bees.——lIt appears that small birds such as the silver-eyes (Zosterops) and the English sparrow are in New Zealand often killed by adhesion to the viscid carpels of Pisonia brunoniana or P, sinclairi, Pisces.—In a letter received by Professor Liversedge from Mr. investing gelatinous membrane about 34%4™ thick.

The members of the group Physostomi tend to retain the pelvic limb more or less nearly in its primordial position throughout life, and no marked tendency towards the approximation of the rudiments of the anterior and the posterior limbs seems to be exhibited by the embryo, as may be seen upon studying the development of a form as typical of the group as the salmon or trout. Such retention of the primordial posterior position of the pelvic fins by the embryos of Physos- tomes supplements those other more unspecialized traits which they possess, viz., the open pneumatic duct, persistent throughout life, and the simpler or more primitive condition in later life of the paraglenal elements (coraco-scapular plate in the embryo), commonly differentiated in the adult into hyper-, meso- an po- coracoid, in Gill’s nomenclature, whereas in the Physoclisti the mesocoracoid is suppressed. The frequently persistent protop- terygian condition of a portion of median dorsal fin-system, de- veloped as a so-called adipose fin, is another embryonic character retained by many Physostomes. While the foregoing characters are unquestionably of value as determining the relative position of the two groups under discus- sion, I would now call attention to some embryological phe- nomena which demonstrate beyond any doubt that the Physo- clisti have descended from the Physostomi. In the young larva of Lophius, or the angler, taken from the egg shortly before hatching, A. Agassiz? has shown that the pectoral and pelvic fin-folds arise, the latter behind the former and almost synchronously, as lobate diverticula of the epiblast, into which mesoblast has been thrust outwards, and with their bases nearly horizontal. In this relation of position as anterior and posterior paired outgrowths they develop just as do the rudi- ments of the paired fins of the Physostomous salmon embryo; but the two pairs of fins are much more nearly synchronous in making their appearance, and are much closer together. The figure of the youngest stage of the angler given by Agassiz shows that there are but four myotomes opposite the interval be- 1 Edited by Joun A.

[ March, tween the pelvic and pectoral fin-folds, whereas in the young salmon, relatively somewhat older, there are at least sixteen myo- tomes opposite the interval between the pelvic and pectoral fin- folds. This fact would seem to indicate that the tendency to shift the pelvic limb forwards must have commenced to manifest itself far back in the ancestral history of Lophius. The sudden translocation of the pelvic fin of Lophius, which now follows in the next stage figured by Agassiz, gives us a clear conception of how the jugular or thoracic position of the pelvic _limbs of Physoclists has been brought about. It also clears away the difficulties which Haswell and Fiirbringer have encountered in reconciling the condition of the nerve supply of such shifted fins with the theory of the origin of the paired limbs from continuous folds or serially homologous rudiments, as developed by Balfour and Dohrn. For, in the next stage, we find the base of the pelvic fin suddenly swung round, down and forward through an arc of nearly 90°, so as to carry the whole structure below the base of the pectoral. This shifting is then carried still further, so that the bases of the pelvic fins are finally situated below and in front of the insertion of the bases of the pectorals. The other equally singular and extraordinary embryonic changes undergone by Lophius we cannot discuss at present, but would refer the reader to the original memoir. This remarkably sudden shifting of the pelvic fins of Lophius embryos, within a period of twenty-four hours, is a fine example of saltatory development, or of how a sudden developmental leap may be manifested, which does not very seriously involve adjacent structures. Embryonic development is, in fact, every- where diverted from its archetypal mode, so to speak, by such interference with the primordial synchrony or primitive order in time and space of the appearance of different organs. It is the business of the philosophical morphologist to keep in mind the import of such phenomena, and to weigh their significance in the discussion of the evolution of organic forms, he nerves, vessels, muscles and bones appertaining to the suc- cessive rays of the median fins are, as is well known, derived from embryonic metameres which are simply more developed or dif- ferentiated in the adult. The cartilaginous rays or actinophores* of the paired fins of the Elasmobranchs and the rays of the un- paired fins of Teleosts are known to sustain such a relation of ~ homonomy to the primary metameres first indicated in the em- ae bryo, though in some types two, three or even five actinophores ~ may stand in a derivative relation to such a single embryonic ‘Segment or somite. There is also much ground for the belief that in the paired fins of Teleosts it is possible to trace such a relation _ between the somites over which they originally arose and the _actinosts or actinophores which constitute their axial skeletons, : ae skeletal elements which afford support to the true fin-rays 1885.] Embryology. 317 much as the Teleostean paired fins have been specialized and altered in the course of the history of the phylum. If it is, therefore, found difficult to trace the nerve supply of the pelvic fins which have been thus shifted into a jugular or tho- racic position to segments above them, or to reconcile their mode of innervation with the lateral-fold theory of their origin proposed by Balfour, the comparative anatomist who confines himself to the study of adult structures should not be surprised, for he can know nothing of the translocation of the whole fin-rudiment forward and downward unless he is acquainted with the process which brings this about. Neglecting this, he remains ignorant of what embryological investigation and investigators might do for him, though he will often criticise the conclusions of the latter upon the basis of his knowledge of adult structures, which, as in the case above instanced, would manifestly be insufficient to enable him to get at the truth. This interesting example of the value of embryological observations as the basis for deductions in scientific morphology, reminds the writer of what Bruch’ has said, to the effect that, “In the kingdom of nature, as in history, all that has become is to be understood only through its decoming.” Lophius is an extreme type, yet other equally interesting forms have been described, traced and figured by Mr. Agassiz; for ex- ample, Gadus does not bud out the rudiments of its pelvic fins so early as Lophius, though another form, Mallotus (= Onos), seems to bud out the pelvic limb nearly as soon as the embryo angler. Gadus is evidently intermediate —/John A. Ryder. DEVELOPMENT OF THE VIVIPAROUS EDIBLE OysTER.*—In this essay, the text being duplicated in Dutch and French, Dr. Horst brings together about all the information of value which has been acquired by his pfedecessors and contemporaries, and also gives an account of his own investigations, especially those which relate to the development of the shell-gland and gastrula, which he had, however, first published two years ago. The gastrula is the first shell-gland_ on nearly the opposite side of the blastula? The mouth is formed at the time of invagination of the gastrula; the anus is formed later, and is broken through at the end of the gas- trular pouch of endoblast, which blends with the ectoblast, which also becomes perforated where the two blend. The mantle cavity is formed by the appearance of a space between the posterior mar- 1 « Alles Gewordene, im Reiche der Natur, wie in der Geschichte ist nur durch sein Werden zu begreifen, und die Entwickelungsgeschichte ist in diesem Sinn fiir den Naturforscher vollkommen dasselbe, was die Weltgeschichte fiir die Menschheit (Wirbeltheorie des Schadels).

[ March, gins of the larval valves, lined with ectoblast (mantle), into which the vent opens. e anterior adductor muscle degenerates after fixation, when its function is assumed by the posterior adductor, which develops after the former. The cephalic ganglion origi- nates from an epiblastic thickening situated in the center of the - trochal disk or velum. e larval shell is homogeneous; but at the hinge there are two small teeth separated by an interval from each other. The earlier stages are copied from Mobius, who incorrectly represents the nucleolus of the ripe egg as being spheroidal, whereas the writer has shown it to be a double body in the ova of the three species, including O. edulis, investigated by him.) Dr. Horst’s more recent investigations upon the early growth and fixation of the fry or veliger stage of O. edulis and its meta- morphosis into the “spat” are of great and significant interest. Carrying out more fully a suggestion made by the writer in 1881, Dr. Horst used a wooden frame, into which could be fixed a large number of glass slides, such as are used by microscopists. This frame, with its contained slides, some of which were coated with hydraulic cement, was immersed for a period of seventy-two hours in waters where free-swimming oyster larva were known to exist, at the end of which time spat was found adhering to the slides, measuring 0.24™" in height (q}+ of an inch). After fixa- tion, which seems to occur in the same way as in the American species, the permanent shell is formed or built up by the mantle beyond the margins of the valves of the fry, a homogeneous membrane, subdivided internally into polygonal spaces or areas, being first laid down by the mantle border. In these prismatic areas of the periostracum, calcification occurs by the deposit of calcic carbonate, and the shell is thus moulded upon the mem- branous matrix of conchioline. Attachment and growth of the young edible oyster, according to Horst, is very similar to that ot the American species, as described by the writer (Bull. U. S. Fish Commission, ii, 1882, p. 383). The outgrowth of the first branchie as two series of distinct ciliated processes projecting into the mantle cavity of the spat is interesting as showing that the more primitive condition of the lamellibranchiate gill was much simpler than in the existing adult oyster.

The relative sen- sitiveness to heat in different parts of the body is not the same in different individuals. 2. It differs much less in different parts of the same individuals than the sensitiveness to pressure or power of localization, the greatest difference for heat being as three to one ; while for pressure it is at least as five to one, and for locali- zation as sixty to one. 3. The parts in which the other cuta- neous senses are most acute are not the same as those in which there is greatest sensitiveness to heat. 4. Of the parts examined, the tip of the index finger is the least sensitive ; in the other parts where the sense of locality is from five to thirty times as dull, the thermal sense is from two to three times as acute. 5. The thermal sensitiveness bears no definite relation to the thickness of the epidermis.” On the contrary the time necessary for an in- crease of temperature to be perceived depends directly upon the thickness of the epidermis which is heated ( X.

Wharton Jones found that the veins in the bat’s wing underwent rhythmic expansions and contractions even after there was good reason to suppose that the influence elo through the vessels of an excised, but living muscle, undergoes alternate acceleration and diminution which can only be explained changes in the caliber of the muscular vessels. 320 Generat Notes.

If the finger-nail be drawn once or twice up and down the mid- dle of the forehead a red streak remains which may persist many minutes. This streak undergoes variations in width and brightness, some of which correspond to the heart-beat, others to the movements of respiration, and still another series have a slower rhythm of some twenty seconds interval; these last changes probably have their origin in purely local contractions of the capillary walls—//.

A disk of platinum fits closely in the tube and is in contact with the oil column whose movements it follows perfectly without allowing the escape of oil round its rim, An aluminium rod of proper length, bearing a writing point at one end, is fastened to the center of the platinum disk, and the piston rod passing through a hole in a cap at the end of the glass tube is kept moving in the center of the latter. —Jt.

THE ORIGIN OF FIBRIN FORMED IN THE COAGULATION OF BLOOD. —Research upon the cause of blood clotting has been rendered very difficult because of rapidity of the process of coagulation in the blood of most animals. Dr. Howell has discovered that the blood of the terrapin clots very slowly and offers unequaled advan- tages for the study of its chemical changes. A sample of this blood - single chemical body, fibrinogen, which exists pre-formed in the blood plasma, into fibrin under the influence of fibrin-ferment, which is a product of the dissolution ot white blood corpuscles. —Stud, Biol.

But there are several instances in which the connection does not seem to have been so clear. Tüke investigated the case of an old man who at will could increase his heart rhythm by twenty beats per minute. A Lieut. Townsend could restrain respiration and heart beat until he fell into a death-like condition and the body began to grow cold, Professor Tarchanoff reports a series of ex- periments carried out on a student who could voluntarily hasten his heart-beat from about 90 to 120 beats per minute. The patient declared that this acceleration was not preceded by any special emotion, and mere thinking of the condition would not produce it, but that a direct and fatiguing effort of the will was necessary to cause the quickening. Comparative measurements showed that during the acceleration there was no constant alteration of the respiration, but that the blood pressure uniformly rose with the heart beat.—P/fliiger’s Archiv. Bd., 35, p. 109. PSYCHOLOGY. INTELLIGENCE OF A SETTER Doc.—In the winter of 1880 I pur- chased in the East a dog puppy out of a purely bred English Gordon setter bitch, by the well known prize-winning Irish water spaniel, Bramton Barney. He was the only puppy in the litter and no other puppies came from the same cross, for the reason that the bitch died soon after, and bringing the puppy here he was named Barney, and keeping him in the office where there were several persons employed, his exceeding good nature was courted and his naturally pleasing (aside from his determination), yet nervous disposition was en- couraged. : After a little training Barney took to retrieving, but his more noticeable traits was the working up of some mischievous act of his, which, though puppy-like, would at times be so unlike the or- dinary as to appear to the observer as original. In the spring following, when but about six months old, he re- trieved his first duck from water, and this one being a wounded ruddy duck made the young “ dropper ” labor hard to make good the catch and bring the bird to me, as it was yet alive. ; From this time on there seemed no difficulty in getting him to go for a wounded or dead bird at any time, but owing to his exceedingly stubborn nature he was very hard to govern in such manner that he would perform the service as work and not as yards from shore, breaking the ice which, by the way, was not very thick. Barney without a whine followed after me and without =- VOL. XIX.—No. II. 2I 322 General Notes. [March, noise remained by my side until the first duck was dropped, which was in time nearly half an hour, and the duck fell in the open water seventy-five yards away. The ice was not quite strong enough te hold up the dog and in his struggles to get through about fifty yards of the ice before reaching the open water he had a very tedious time of it. At last he reached the duck and taking it in his mouth, swam first towards the broken ice which he had made and then turning to one side broke a new path away, but not in the direction of where I was standing, but in a direct line for the shore, deviating only as forced to evade a too heavy growth of rushes. Arriving upon shore he placed the duck alongside of some ammunition sacks I had left near a log, and upon the log and overcoat, thinking that perhaps this would have a tendency to drive the ducks and other birds coming up near the bank to shear off towards my blind in the rushes. His desire to get to this log in as short a way as possible was evident, for as soon as he dropped his duck, he at once pulled the coat off the log, but to the east side and, lying down upon it kept only his head exposed to the piercing north-west wind as it struck the right side of the log which lay almost par- allel with the points of the compass north and south. This he con- tinued during my shooting for the forenoon, only changing when I shot a duck, when he would at once run as rapidly as he could to the channel he had made—swim out to where the duck had dropped, pick it up and return to place it with the first and then to again resume his position behind the log, with his head above on the lookout. Even as he grew in years his good nature of puppyhood did not forsake him; in the kennel he was the popular dog. All the female dogs and puppies, liked him and it seemed to him the greatest pleasure when a puppy was being hurt to rush up and chase the abuser away. He was also given to particular fancies. Some men he did not like, while others instead he was particularly fond of. _ Asa companion he was with me going down the Arkansas river, in the winter and spring of 1882; to Labrador, in the sum- mer of the same year and many other nearly similar trips. Dif- ferent from most dogs I have observed; while he at times was as jealous as any, at others he was quite indifferent. His human ac- quaintances named him the “ noble dog,” and this must have been a like opinion among his canine friends. In the kennel where he was kept for a considerable time were quite a number of dogs and bitches, and scarcely at any time but that there were a number of puppies there also.. In this kennel was one highly bred pointer of large size, a powerful animal, but _ with a very miserable disposition. It was an almost continuous occurrence for Barney to play ~ with one or more of the puppies, permitting them to pull hi a arrest i pu is ears, oy tail and other parts of the body ; sometimes when three or four of 1885.] Psychology. 323 them would take position at opposite points, and pull with all . their strength, he did not growl or get vexed, for at such times he was in his element and enjoyed it the more when he could jump high into the air to frighten his young friends. The pointer instead would not permit a puppy to approach him, in fact had so bitten a couple that they had died. From some cause this pointer, Wad, and Barney were the worst of enemies, and in consequence there were many battles, and the pointer being the more powerful would have ruined his foe, were it not for the support of one of the bitches—an Irish water spaniel. This bitch, Frank, would rush up at once upon seeing Barney thrown under his adversary and catching the pointer by one of his hind legs, start off with a sudden jerk; the result would be that Barney would once more come to his feet and in the end be- cause of his being shaggy would get the best in the fight with the vicious, yet plucky pointer. In all these fights should Barney get bitten so that blood would be shown there seemed to be a perfect panic amongst the bitches and puppies. ; ne instance in particular is noticeable. Returning to my office one afternoon I observed many people running towards the kennel, which was in the rear of the office. : A workman who had been engaged in the kennel was hurriedly running up the street to me. He said that Barney, and the poin- ter were having a big fight, and that Barney, assisted by the bitches, was eating up the pointer. ; Upon arriving within the kennel my greatest surprise was to see the grown bitches chasing Wad—whose coat naturally pure white was now covered with blood—around the yard as rapidly as could be, Frank the more savage of the number ; while Barney with a lot of puppies around him was assisted by them in licking his wounds. The workman, who at the time the fight began was at work on the south side of the kennel in cleaning outa bath- ing tank, informed me that Wad was lying in the shade of the high hold of Wad’s ear led him away from this shady place to the north side of the kennel where the sun shone very hot. Here he left him and at once went back to the shady place to lie down, from only a few days, attempted to drive Barney ; ins Barney growled and would not leave—showing plainly his dispo- sition to attack the workman. : Wad had followed Barney, but did not offer fight until after ey’s growling, when he at once rushed upon him. Ina sie moments Barney was the “under dog” in the fight and continue so until Frank as usual came to the rescue. This she did, sev- 324 General Notes. [March, eral times catching Wad by one hind leg and giving Barney a chance to get up again. Several witnesses who climbed up and saw the fight over the high board fence corroborated this part of the statement by the workman. When I saw Barney after the fight he was lying in the chosen place he had driven Wad from, with all the puppies and bitches around him.— To de continued. ANTHROPOLOGY. ' Tue Proro-HELveEtTiAns (continued)—The age of bronze shows a marked advance on preceding ages. The villages of that period were more extensive, the dwellings, as is shown by the planks and main timbers which still exist, larger. In each village there appears to have been an open place where work was undertaken . that could not well be done indoors. The discovery on the sites of the lacustrine villages of Neuchatel and Bienne, of molds, crucibles, metal broken for the melting pot, damaged and half- repaired tools and weapons, is sufficient to disprove the theory that the workshops were on the land. There is reason to believe that the stations of the bronze age, unlike those of the stone age, were more or less contemporaneous. Except in unimportant de- tails, the remains of that period hitherto brought to light possess the same general features, and none of the villages appears to have outlived the others. Some of the swords of the bronze age are elegantly shaped and exquisitely worked. They were probably worn by the chiefs, and served rather as badges of authority than as weapons of offense. The form of them is that of a willow leaf, and their length varies from seventeen to twenty-three inches. The blades are generally ornamented with several parallel bands and fastened to the hilt with rivets. One of the finest specimens found at Lor- cas, in addition to'the bands, is ornamented with a series of punc- tured lines, and the hilt, which is bossed in the center, has a short cross-guard. The total length of the blade is 23.89 inches (six- ty-seven centimeters), the hilt measures only eight centimeters. None of the hilts are much larger, and judging by the size of ranean cto the lake-dwellers must have had remarkably small The hilt of a sword found at Mcerigen appears to have been -ornamented with ivory or amber, and its blade of cast bronze is inlaid with thin plates of iron, the metal, which is now the com- ‘monest of all, being in that age the most precious. The blades =~ Of all these swords are straight and pointed, and designed rather _ for thrusting than for cutting. . But the gem of Dr. Gross’s collection is a steel sword found at 3 _ Corcelettes.. The fact that it is steel has been proved by analy- oe . : * Edited by Prof. Otis T. Mason, National Museum, Washington, D. C. 1885. | Anthropology. 325 sis, and the specimen is unique among lacustrine finds. The blade, which has suffered somewhat by fire, is 25.58 inches long, straight and pointed, and the waved lines with which it is embel- lished are evidently the work of some pre-historic engraver. Who were the forgers of this weapon is a question Dr. Gross dis- cusses at some length and, having regard to the undoubted skill of the Lacustrians as metal workers and to other circumstances, he leans decidedly to the opinion that it was wrought by them- selves ; yet seeing that no other arm of the same material has been found elsewhere, the correctness of this conclusion is per- haps open to doubt. Among the objects brought to light by the labors of Dr. Gross are bronze daggers, highly ornamented hatchets, chisels, gouges, knives, hammers, anvils, needles, tools for net-making, fishing-tackle, buttons, chains, spoons, spear- heads, arrow-points and rings, bracelets and other ornaments in great variety. Strange to say, saws, though they seem to have abounded in the stone age, are rarely found among the vestiges of the age of bronze. The total finds of them in the Swiss lakes do not exceed half a dozen, of which two are in the collection of Dr. Gross. One was found at Mcerigen, the other at Auvernier, and both appear to have been used as frame saws. Another in- teresting find was that of a distaff at Lorcas (a stone age station) and a bundle of linen yarn, which, if it were not slightly carbon- ized, might be passed off as having been spun yesterday. No remains of looms have been found, but the discovery of linen exactly like the studs which now adorn the fronts of gentlemen’s shirts, and double buttons in no way distinguishable from the solitaires used for fastening wristbands. Ornaments of gold are chariot wheel and bones and skeletons of horses, put an end to all doubts on the subject. Some of the bits are remarkable speci- 326 General Notes. [March, mens of metallurgic art. One of them is a sample of the type still in common use, both in England and on the continent. The mouth-piece is jointed in the middle and twisted, the cheeks are furnished with “dees” for holding bridle and curb-chain ; and in shape and fashion the Proto-Helvetian bit differs hardly at all from the “snaffle” of English grooms and harness-makers. But it is much smaller (nine centimeters, 3.50 in. long.) than the modern bit, a fact which, together with the smallness of all the equine bones that have come to light, points to the conclusion that the horses of the bronze age were little, if any, larger than Exmoor ponies, Professor Virchow, to whom Dr. Gross has submitted the skulls found by him at Auvernier, declares that the brain capacity of the lake-men was equal to that of the men of our owntime. Their conformation, their cerebral volume, the peculiarities of their su- tures, place them on an equality with the highest type of Aryan skulls. That people so richly gifted by nature should have suc- ceeded so remarkably in the struggle for existence, affords no grounds for surprise. There was nothing in common between the lacustrine communities and the savage tribes whom a fatal law condemns to extinction so soon as they come under the influence of a civilization higher than their own. The lake-dwellers pos- sessed a singular aptitude for progress, a rare capacity for adapting themselves to their environment, and making the most of their advantages. The skulls examined by Dr. Virchow are doubtless those of in- dividuals who fell into the water by accident, possibly at the time of the great fires in which nearly all the villages of the bronze age seem to have perished; for the discovery at Auvernier of a place of sepulture, shows that the lake-dwellers disposed of their dead by laying them in the ground. This cemetery contained the bones of about twenty individuals, and the presence among them of stone and bronze articles, their positions on the lake shore, opposite a range of piles, leaves no doubt that the remains are of lacustrian origin. The appearance of the ground denotes the ex- istence of many other tombs; but the cost of exploring them has hitherto hindered the making of further explorations. As touching the antiquity of the lake-dwellings of Proto-Hel- vetia, there is very little to be said. No medals, coins, or other relics, whereby the date of their erection can even be approxi- mately determined, have been found. It may, however, with cer- tainty be inferred, from the absence of anything Roman, that the lacustrian vanished from the scene before the appearance in Cen- tral Europe of the legions of the eternal city. According to the calculations of Von Sacken, moreover, the Necropolis of Hall stadt, which is admittedly more modern than the lacustrian sta- os tions, dates from about 500 A. C., and as there is good reason to believe that several centuries elapsed between the destruction of 1885.] Anthropology. 327 the lake-dwellings, and the making of the Necropolis, the former event must have come to pass 800 to 1000 years before the Christian era. The duration of the ages of stone, copper and bronze, is a matter of pure conjecture. All that can be regarded as certain, is that it was very long. In the opinion of Dr. Gross, and of other erudite Swiss antiquaries, several series of centuries —perhaps twenty or thirty—must have elapsed between the time when the first piles were driven into the beds of the Swiss lakes, and the time when lacustrine civilization reached its highest development. We shall probably not be far out, then, if we assign to the oldest of the lake-dwellings an antiquity of not less than six thousand years.—Contemporary Review, Fuly, 1884. WESTERN TRIBAL AND LocaL Names.—Recent investigations of a linguistic purport on the Western States and Territories have yielded many interesting results, which may be fully relied on, be- cause they were made and verified on the spot. Of ¢rzbal names we mention the following: Bidai, a tribe in Southern Texas, of unknown affinity, The Caddo term bidai means drushwood, thicket. Kichai, a tribe affiliated to the Wichita tribe ; from the Wichita | term kitsa, water. The Wichita Indians call a Kichai Indian, Kiétsash kuétsa, the Red river of Louisiana: Kitchka. The Caddo Indians once were in the habit of wearing nose- rings, and are still called by other tribes “ Pierced-Noses.” The Kayowé style them Mon-sépti, the Comanches Nasomonrhta ; “ring-nosed.” They call themselves Assinai, which is the name of a populous tribe once seen in the center of Texas, by C. de la Salle (about 168 a headdress (siya feather), the other: “painted arrows” is de- rived from pak arrow, nábor “ striped.” The Kayowé name for that people, ’Ahiadl, is said to refer to their homes near cotton- wood trees. : ; The Apaches of Arizona are called by the Comanches Hitashi or with the full form: Hiitashi nap: moccasins turned up at the toes. Né ura’htd hitashi nap signifies: “ I wear moccasins turned up,” and a “ pug-nose”’ is called mui tar; ` Among the local names we point out the following : : Mobitée, a rising town in the Panhandle of Texas, is called so from the Comanche term: mobitai, yee Several creeks and | rivers in the vicinity are called by the same name. Abilene, a town nee railroad Station of Northwestern Texas: from avelino, the Mexican name of the peccary or musk-hog, fre- quent in some portions of Texas and old Mexico. — : Ozark, the name of this ridge is of French origin, and a muti- © 1 Ne, or ném is the Cémanche term for people. 328 General Notes.

SEMPER’S METHOD OF MAKING DRIED PREPARATIONS.—Semper’s method, published in the Sitzungsber. d. phys.-med. Ges., Wirz- burg, 1880, and in the Zoolog. Jahresbericht for 1880, has been redescribed in detail by Dr. Sharp.! 1. Place the object in a weak solution of chromic acid (4-1 per cent), six to twenty-four hours, according to its size and nature. For small animals, such as annelids, gastropods, frogs, mice, &c., six to eight hours are sufficient. 2. Transfer to a large quantity of clean water, which must be often renewed until the acid has been so far withdrawn that the water remains uncolored by it. This part of the process may be much shortened by allowing a current of water to flow through the vessel. The usual time is from ten to twenty hours. 3. Treat with thirty to forty per cent alcohol ten to twenty-four hours, with sixty to seventy per cent alcohol two or three days (with larger objects a week), with ninety per cent alcohol two or three days or more, and finally with absolute alcohol.? 4. Transfer to turpentine and leave it until it becomes thor- oughly saturated (two to three days). With large objects it is best to change the turpentine once. 5. Place the preparation in the air, in order to evaporate the turpentine, protecting it carefully from dust. e preparation soon becomes white, resembling the whitest kid. It is light, stiff and, on account of the resin contained, per- fectly insect-proof. If hollow organs (stomach, bladders, lungs, &c.) are prepared, they may be inflated with air after they have remained a short time in turpentine, by so doing much space, and consequently much alcohol, are saved Professor Semper keeps his preparations in dust-proof, glass boxes, in which they can be seen from both sides. To the five steps of the process a sixth, discovered by Semper a few years ago, is given by Dr. Sharp. It consists in placing the prepared object in a solution of glycerine and sugar, which brings back almost entirely the original color in many cases.

CAMPBELL, T has often been observed that in certain localities a certain species of timber will prevail, or be more numerous than any, and sometimes than every other kind. It has been further ob- served that when anji prevailing timber has been cleared away, and the land allowed to grow up again in timber, that some other species will prevail. This, I think, has often been erroneously attributed to the inability or indisposition of the soil to repro- duce the former prevailing timber. I have observed much on this subject, and I never could see any important difference in the ability or disposition of the soil to nourish any of the different kinds of native trees, and also no important difference in the suc- cess in planting and starting them. My observations convince me that it all, or mainly, lies in the favorable condition of the ground to receive the seeds of the various species of timber when it happens to fall thereon. A sycamore in the Wabash region will grow as large and rapidly on ` the uplands, where they are seldom found, as in the sandy bot- toms along the margins of the streams, where they seem to best thrive. A white oak when planted will grow as well in the low river bottoms, where they are never or seldom found, as on the hills and ridges near by,.where they seem to be the spontaneous product of the ground. ; But if an acorn should be blown from a white oak on the hills into the low bottoms beneath, it would fall on ground very un- favorable to the sprouting of such acorns, and it would rot where it fell. So, on the other hand, if a sycamore ball (which contains VOL. XIX.—NO. IY, 22 338 Why certain kinds of Timber [April, one thousand to two thousand seeds) should, in the spring time, be blown to pieces after the winter’s freeze, and their needle-like seeds be blown upon the adjacent hills, very few of them would light on ground favorable to sprouting them. Occasionally we find a lone sycamore on the uplands, standing among the oak, beech, poplar and other upland timber, and every year bearing its quota of seed and shedding them on the adjacent ground by the million, none, or very few of which, ever take effect, and for rea- sons before hinted at, but which will be more fully explained further on. The sycamore seed must fall on ground, warm, very moist, but not absolutely wet, and sufficiently bare for the sun to shine on it the greater part of the day. Otherwise it may not sprout. The acorn, on the other hand, falls a little while before the leaves fall. If it falls on very moist ground it rots. If it falls on the leaves of the former year, and is shaded enough to prevent drying or baking from the sun, and is covered lightly by the fall of the cur- rent year’s leaves, or by a chance wind has the old leaves drifted on top of it, a slow rain with subsequent sunshine will sprout it. It will send out little rootlets which bore through the underlying old leaves and penetrate the ground, and once started, no weather or climatic conditions will kill it. The same is true of the seed of the hickory, beech, sugar maple and other upland trees. During the past two years my work has been on and about the Wabash river banks and its bottoms (flood-plains), and I have discovered why it is that in some parts of these bottoms one kind of timber, as sycamore, will take complete possession of a few acres, while at or near by the cottonwood will prevail almost to the exclusion of everything else, and at other places the soft or water maple will do likewise, and at still another the water elm will monopolize all the space on which a grown tree can stand for several acres. It comes about in this way. The balls of the sycamore, after undergoing the winter’s freeze, are dissolved so that the sepa- rate, needle-like, or more properly pin-like seeds (as the outer end has the germ of the root, and swells into a bulb like a pin- head) are blown by the wind, the little “ fuz” they hold enabling them to float a great way both in wind and on water. They begin falling early in the spring months, and if a flood is receding at the time, they stick to the soft, moist banks wherever they 1885.] prevail in certain Localities. 339 touch them, and particularly along the highest part of the sand bars. Were it not for the subsequent floods the same spring, there could no other trees grow, as the sycamore, being the first to shed, would seed all the tree-growing space (each large tree bearing one hundred and fifty million seeds), and their broad leaves would shade the ground till nothing else could sprout. But during their early infancy they are easily killed by an over- flow, and this ill fortune happens to the greater portion of them. The cottonwood is the next in order of shedding seed. If an- other flood is receding while the cottonwood is shedding, this flood will have killed all the sycamores which it covered for only a few days, and will sprout all the cottonwood seed that may fall on and along the banks and bars. As the earlier floods are gen- erally the highest there will be some sycamores not reached by the following floods, and they will hold sway along that margin. If, when the cottonwoods are a few inches high, another flood follows, they too will be killed to the extent that they are kept under water a few days. \ Next to the cottonwood the soft, or bottom maple sheds its seed. If a flood is receding this seed will occupy all the space, as, having a smaller leaf than the sycamore or cottonwood, they will grow closer together. They in turn may be killed by a flood when they are very young. I have forgotten the exact time that each of these trees sheds its seed, something will of course depend on the forwardness of the spring. But along the Wabash banks, last spring, I could see three belts of young trees, and distinguish them by their general appearance. The farther off, the plainer these belts show, till lost to view. The upper belt was sycamore, the second (downward) cottonwood, and the third soft maple. In June following there came a bigger flood than any that caused the seeds to sprout, and killed all of them. There was a much bigger flood in the pre- ceding February, but no seed fell then. It will sometimes happen that the flood that plants the syca- mores will be the last one for that year, and when they have lived through one summer they are safe from any danger from over- flow. In still other seasons it will happen to favor the cotton- wood, or the maple, or elm, or willow. New bars are all the time extending from the lower ends of the old ones, and as the eleva- tion of these will be such as to be sometimes flooded once and 340 Why certain kinds of Timber prevail, etc. [April, not again for that year, the trees that shed their seed with the flood that barely covers such bars will plant them to overflowing fullness of their kind, and once they are secure from other floods they live out their time of two hundred to three hundred years. The upper surface of the interior of the bottoms (back from the rivers) is built up by sedimentation, and when built above the height of the average floods, the burr oak, black walnut, buck- eye, pawpaw and bottom hickory make their appearance. Such sycamores, cottonwoods and maples as live long enough to be relegated to the interior (as very few of them do) by the bottoms building riverward away from them, do not and cannot reproduce themselves, as the conditions that sprout their seeds have moved away from them. They die at the end of three hundred years at most, and leave no heirs to the soil. How do the occasional lone, stray sycamore and cottonwood find their way to the uplands? I can see how in one case it was not only possible but very probable. Five miles south-east of where I am now writing (Rockville, Indiana) is a pasture of hill land, so fenced as to include a section of a small stream at the foot of a hill facing north. There stand several half-grown syca- mores which bear and shed their seed in this corner watering place. There these seeds are sprouted. There the cattle and horses resort for water. Every thimbleful of mud that may stick to their hoofs is liable to contain from one to five half- sprouted seeds, which are carried up the hillside and on the up- land, as the cattle and horses return to their grass, and dropped where the sun takes up the unfinished work of growing the tree. The result is, that on every square rod of ground near this water- ing place stands one to five sycamores, varying in age from one to ten years, and they diminish in number as the distance from the watering place increases. It has been used as a pas- ture about ten years. I remember when it contained no syc- amore at all. Just outside of the pasture fence, to the east- ward, the land has never been fenced. The cows may drink where they please, and there are no sycamores scattered over the adjacent hills. If any seeds are thus carried there, the forest leaves and shade prevent their sprouting and growing. But along the little sand and gravel bars of the stream, they sprout as thick as grass, only to be killed by the floods from the early summer showers. 1885. ] On the Evolution of the Vertebrata, etc. 341 From this I infer that two hundred to three hundred years ago the deer, elk and buffalo in their many wanderings across streams and over hills, have occasionally carried in their hoofs partly sprouted seeds, and dropped them on the hills where the sun- shine was unobstructed, and the trees thus got their footing, and once getting it were able to stand afterward. These are the only kinds of trees I have observed, but I presume a similar law gov- erns the distribution and self-planting of them all. 10: ON THE EVOLUTION OF THE VERTEBRATA, PRO- GRESSIVE AND RETROGRESSIVE. BY E. D. COPE. (Continued from page 247, March number.) Tue REPTILIAN LiNE—CONTINUED. igs the first place, this line departs with lapse of time from the primitive and ancestral order, the Theromorpha, in two re- spects. First in the loss of the capitular articulation of the ribs, and second in the gradual elongation and final freedom of the suspensory bone of the lower jaw (the os quadratum). In so departing from the Theromorpha, it also departs from the mam- malian type. The ribs assume the less perfect kind of attach- ment which the mammals only exhibit in some of the whales, and the articulation of the lower jaw loses in strength, while it gains in extensibility, as is seen in the development of the line of the eels among fishes. The end of this series, the snakes, must therefore be said to be the result of a process of creation by degeneration, and their lack of scapular arch and, fore limb and usual lack of pelvic arch and hind limb are confirmatory evidence of the truth of this view of the case. Secondly, as regards the ossification of the anterior part of the brain-case. This is deficient in some of the Theromorpa, the an- cestral order, which resemble in this, as in many other things, the cotemporary Batrachia. Some of them, however (Diadecti- dæ), have the brain completely enclosed in front. The late orders mostly have the anterior walls membranous, but in the strepto- stylicate series at the end, the skull becomes entirely closed in front. In this respect then the snakes may be said to be the highest or most perfect order. | As regards the scapular arch, no order possesses as many ele- 342 On the Evolution of the Vertebrata, [ April, ments as thoroughly articulated for the use of the anterior leg as the Permian Theromorpha. In all the orders there is loss of parts, excepting only in the Ornithosauria and the Lacertilia. In the former the adaptation is to flying. The latter retain nearly the Theromorph type. An especial side development is the modification of abdominal bones into two peculiar elements to be united with the scapular arch into a plastron, seen in the Tes- tudinata. In this part of the skeleton the orders are generally degenerate, the last one, the Ophidia, especially so. The pelvic arch has a more simple history. Again in the Theromorpha we have the nearest approach to the Mammalia. The only other order which displays similar’ characters is the Ornithosauria (Dimorphodon, according to Seeley). In the Din- osauria we have a side modification which is an adaptation to the erect or bipedal mode of progression, the inferior bones being thrown backwards so as to support the viscera in a more poste- rior position. This is an obvious necessity to a bipedal animal where the vertebral column is not perpendicular, as in birds. And it is from the Dinosauria that the birds are supposed to have arisen. The main line of the Reptilia, however, departs from both the mammalian and the avian type and loses in strength. In the latest orders, the Pythonomorpha and Ophidia, the pelvis is rudimental or absent. © As regards the limbs, the degeneracy is well marked. No reptilian order of later ages approaches so near to the Mamma- lia in these parts as do the Permian Theromorpha. This approxi- mation is seen in the internal epicondylar foramen and well devel- oped condyles of the humerus, and in the well differentiated seven bones of the tarsus. The epicondylar foramen is only retained in later reptiles in the Rhynchocephalian Hatteria (Dollo); and the condyles of the Dinosauria and all of the other orders, excepting the Ornithosauria and some Lacertilia, are greatly wanting in the strong characterization seen in the Thero- morpha. The posterior foot seems to have stamped out the greater part of the tarsus in the huge Dinosauria, and it is re- duced, though to a less degree, in all the other orders. In the paddled Sauropterygia, dwellers in the sea, the tarsus and carpus have lost all characterization, probably by a process of degen- eracy, as in the mammalian whales. This is to be inferred from the comparatively late period of their appearance in time. The 1885. ] Frogressive and Retrogressive. 343 still more unspecialized feet and limbs of the Ichthyosaurus (Ich- thyopterygia) cannot yet be ascribed to degeneracy, for their his- tory is too little known. At the end of the line the snakes pre- sent us with another evidence of degeneracy. But few have a pelvic arch (Stenostomide Peters), while very few (Peropoda) have any trace of a posterior limb. The vertebrz are not introduced into the definitions of the orders, since they are not so exclusively distinctive as many other parts of the skeleton. They nevertheless must not be over- looked. As in the Batrachia the Permian orders show infe- riority in the deficient ossification of the centrum. Many of the Theromorpha are notochordal, a character not found in any later order of reptiles excepting ina few Lacertilia (Gecconidz), They thus differ from the Mammalia, whose characters are approached more nearly by some of the terrestrial Dinosauria in this respect. Leaving this order we soon reach the prevalent ball and socket type of the majority of Reptilia. This strong kind of articula- tion is a need which accompanies the more elongated column which itself results at first from the posterior direction of the ilium. In the order with the longest column, the Ophidia, a sec- ond articulation, the zygosphen, is introduced. The mechanical value of the later reptilian vertebral structure is obvious, and in this respect the class may be said to present a higher or more perfect condition than the Mammalia. In review it may be said of the reptilian line, that it exhibits marked degeneracy in its’ skeletal structure since the Permian epoch ; the exception to this statement being in the nature of the articulations of the vertebrze. And this specialization is an adap- -tation to one of the conditions of degeneracy, viz., the weakening and final loss of the limbs and the arches to which they are at- tached. r The history of the development of the brain in the Reptilia presents some interesting facts. In the Diadectid family of the Permian Theromorpha it is smaller than in a Boa constrictor, but larger than in some of the Jurassic Dinosauria. Marsh has shown that some of the latter possess brains of relatively very narrow hemispheres, so that in this organ those gigantic reptiles were degenerate, while the existing streptostylicate orders have advanced beyond their Permian ancestors. There are many remarkable cases of what may now be safely 344 On the Evolution of the Vertebrata, [ April, called degradation to be seen in the contents of the orders of reptiles! Among tortoises may be cited the loss of the rib- heads and of one or two series of phalanges in the especially terrestrial family of the Testudinidae. The cases among the Lacertilia are the most remarkable. The entire families of the Pygopodide, the Aniellidz, the Anelytropide and the Dibamide are degraded from superior forms. In the Anguide, Teidz and Scincide we have series of forms whose steps are measured by the loss of a pair of limbs, or of from one to all the digits, and even to all the limbs. In some series the surangular bone is lost. „In others the eye diminishes in size, loses its lids, loses the folds of the epidermis which distinguish the cornea, and finally is en- tirely obscured by the thickening of the cornea and closure of the ophthalmic orifice in the true skin. Among the snakes a similar degradation of the organs of sight has taken place in the order of the Scolecophidia, which live under ground, and often in ants’ nests. The Tortricidae and Uropeltide are burrowing snakes which display some of the earlier stages of this process. One genus of the true snakes even (according to Günther) has the eyes obscured as completely as those of the inferior types above named (genus Typhlogeophis). VII. Tue Avian Line. The paleontology of the birds not being well known, our con- clusions respecting the character of their evolution must be very incomplete. A few lines of succession are, however, quite ob- vious, and some of them are clearly lines of progress, and others are lines of retrogression. The first bird we know at all com- pletely, is the celebrated Archeopteryx of the Solenhofen slates of the Jurassic period. In its elongate series of caudal vertebre and the persistent digits of the anterior limbs we have a clear indication of the process of change which has produced the true birds, and we can see that it involves a specialization of a very pronounced sort, The later forms described by Seeley and ` Marsh from the Cretaceous beds of England and North America, some of which have biconcave vertebrz, and all probably, the American forms certainly, possessed teeth. This latter character was evidently speedily lost, and others more characteristic of the . subclass became the field of developmental change. The parts _ 'Such forms in the Lacertilia have been regarded as degradational by Lankester > . = _ cending one. 1885, | Progressive and Retrogressive. 345 which subsequently attained especial development are the wings and their appendages; the feet and their envelopes, and the vocal organs. Taking all things into consideration the greatest sum of progress has been made by the perching birds, whose feet have become effective organs for grasping, whose vocal organs are most perfect and whose flight is generally good, and often very good. In these birds also the circulatory system is most modi- fied, in the loss of one of the carotid arteries. The power of flight, the especially avian character, has been developed most irregularly, as it appears in all the orders in especial cases. This is apparent so early as in the Cretaceous toothed birds already mentioned. According to Marsh the Hes- peornithide have rudimental wings, while these organs are well developed in the Ichthyornithide. They are well developed among natatorial forms in the albatrosses and frigate pelicans, and in the skuas, gulls and terns; among rasorial types the sand-grouse, and among the adjacent forms, the pigeons. Then among the lower insessores, the humming-birds exceed all birds in their powers of flight, and the swifts and some of the Caprimulgide are highly developed in this respect. Among the higher or true song birds, the swallows form a notable example. With these high specializations occur some remarkable deficiencies. Such are the reduction of the feet in the Caprimulgide swifts and swallows, and the foetal character of the bill in the same families. In the syndactyle families, represented by the kingfishers, the condition of the feet is evidently the result of a process of de- generation. A great many significant points may be observed in the devel- opmental history of the epidermic structures, especially in the feathers. The scale of change in this respect is in general a rising one, though various kinds of exceptions and variations occur. In the development of the rectrices (tail feathers) there are genera of the wading and rasorial types, and even in the insessorial series, where those feathers are greatly reduced or absolutely wanting. These are cases of degeneracy. There is no doubt but that the avian series is in general an as- VIII. THE MAMMALIAN LINE.

Paleontology has cleared up the phylogeny of most of these orders, but some of them remain as yet unexplained. This is the case with the Cetacea, the Sirenia and the Taxeopoda. The last-named order and the Marsupialia can be supposed with much probability to have come off from the Monotremata, but there is as yet no palzontological evidence to sustain the hypothesis. No progress has been made in unraveling the phylogeny of the Cetacea and Sirenia. The facts and hypotheses as to the phy- logeny of the Mammalia may be represented in the following diagram ia Diplarthra Hyracoidea Insectivora Rodentia Chiroptera Proboscidea \ Anthropoidea / Edentata | Carnivora | Amblypoda Quadrumana | Tillodonta Tzniodonta | Creodonta Cetacea Condylarthra Marsupialia Monotremata 1 Except Pantolestes. This order includes the suborders Perissodactyla and Artio- la. 2 Except Mesonyx. 3 Eri naceus. 4 With the suborders Insectivora, Creodonta, Tæniodonta and Tillodonta. 348 On the Evolution of the Vertebrata, [April, It will be readily seen from the above diagram that the discov- ery of the Condylarthra was an important event in the history of our knowledge of this subject. This suborder of the Lower Eocene epoch stands to the placental Mammalia in the same rela- tion as the Theromorphous order does to the reptilian orders. It generalizes the characteristics of them all, and is apparently the parent stock of all, excepting perhaps the Cetacea. The discov- ery of the extinct Bunotherian suborders united together insepa- rably the clawed orders, excepting the bats; while the .extinct order Amblypoda is the ancestor of the most specialized of the Ungulates, the odd and even-toed Diplartkra. The characters of the skeleton of the order Monotremata show that it is nearest of kin to the Reptilia, and many subordinate characters point to the Theromorpha as its ancestral source! In the general characters the Marsupialia naturally follow ina rising scale, as proven by the increasing perfection of the reproductive sys- tem. The Monodelphia follow with improvements in the reproduc- tive system and the brain, as indicated in the table already given. The oldest Monodelphia were, in respect to the structure of the brain, much like the Marsupialia, and some of the existing orders . tesemble them in some parts of their brain-structure. Such are the Condylarthra and Amblypoda of extinct groups, and the Bunotheria, Edentata, Rodentia and Chiroptera, recent and extinct. The characters of the brains of Amblypoda and some Creodonta are, in their superficial characters, even inferior to existing marsupials. The divided uterus of these recent forms also gives them the position next to the Marsupialia. In the Car- nivora, Hyracoidea and Proboscidia a decided advance in both brain structure and reproductive system is evident. The hemi- spheres increase in size and they become convoluted. A uterus is formed and the testes become external, etc. In the Quadru- mana the culmination in these parts of the structure is reached, excepting only that in the lack of separation of the genital and urinary efferent ducts, the males are inferior to those of many of the Artiodactyla, This history displays a rising scale for the Mammalia. . Looking at the skeleton we observe the following ‘successional modifications :? 1 Proceedings American Philosoph. Society, 1884, p. 43. * See the evidence for evolution in the history of the extinct Mammalia. Proceeds. Amer, Assoc, Adv. Science, 1883. 1885.] Progressive and Retrogressive. 349 First, as to the feet, and (A) the digits. The Condylarthra have five digits on both feet, and they are plantigrade. This character is retained in their descendants of the lines of Anthro- poidea, Quadrumana and Hyracoidea, also in the Bunotheria, Edentata and most of the Rodentia. In the Amblypoda and Proboscidia the palm and heel area little raised. In the Carnivora and Diplarthra the heel is raised, often very high, above the ground, and the number of toes is diminished, as is well known, to two in the Artiodactyla and one in the Perissodactyla. (B) The tarsus and carpus. In the Condylarthra the bones of the two series in the carpus and tarsus are opposite each other, so as to form continuous and separate longitudinal series of bones. This continues to be the case in thé Hyracoidea and many of the ' Quadrumana, but in the anthropoid apes and man the second row is displaced inwards so as to alternate with a first row, thus inter-. rupting the series in the longitudinal direction, and forming a stronger structure than that of the Condylartha, In the Buno- therian rodent and edentate series, the tarsus continues to be without alternation, as in the Condylarthra, and is generally identical in the Carnivora. In the hoofed series proper it under- goes change. In the Proboscidia the carpus continues linear, while the tarsus alternates. In the Amblypoda the tarsus alter- nates in another fashion, and the carpal bones are on the inner side linear, and on the outer side alternating. The complete interlocking by universal alternation of the two carpal series is only found in the Diplarthra. (C) As to the ankle-joint. In most of the Condylarthra it is a flat joint or not tongued or grooved. In most of the Carnivora, in a few Rodentia, and in all Diplarthra, it is deeply tongued and grooved, forming a more perfect and stronger joint than in the other orders, where the surfaces of the tibia and astragalus are flat. (D) In the highest forms of the Rodentia and Diplartha the fibula and ulna become more or less coossified with the tibia and radius, and their middle portions be- come alternated or disappear. Secondly, as regards the vertebra. The mutual articulations (zygapophyses) in the Condylartha are flat and nearly horizontal. In higher forms, especially of the ungulate series, they become curved, the posterior turning upwards and outwards, and the an- terior embracing them on the external side. In the higher Dip- lartha this curvature is followed by another curvature of the y ; 350 On the Evolution of the Vertebrata, [April, postzygapophysis upwards and outwards, so that the vertical sec- tion of the face of this process is an S. Thus is formed a very close and secure joint, such as is nowhere seen in any other Vertebrata, Thirdly, as regards the dentition. Of the two types of Mono- tremata, the Tachyglosside and the Platypodide, the known genera of the former possess no teeth, and the known genus of the latter possesses only a single corneous epidermic grinder in each jaw. As the Theromorphous reptiles from which these are descended have well developed teeth, their condition is evidently one of degeneration, and we can look for well toothed forms of Monotremata in the beds of the -Triassic and Jurassic periods. Perhaps some such are already known from jaws and teeth. Inthe marsupial order we have a great range of dental structure, which almost epitomizes that of the Monodelph orders. The dentition of the carnivorous forms is creodont; of the kan- garoos is perissodactyle, and that of the wombats is rodent. Other forms repeat the Insectivora. I therefore consider the pla- cental series especially, I have already shown that the greater number of the types of this series have derived the characters of their molar teeth from the stages of the following succession. First a simple cone or reptilian crown, alternating with that of the other jaw. Second, a cone with lateral denticles. Third, the denticles to the inner side of the crown forming a three-sided prism, with tritubercular apex, which alternates with that of the opposite jaw. Fourth, development of a heel projecting from the posterior base of the lower jaw, which meets the crown of the superior, forming a tubercular-sectorial inferior molar. From this stage the carnivorous and sectorial dentition is derived, the tritubercular type being retained. Fifth, the development of a posterior inner cusp of the superior molar and the elevation of the heel of the inferior molar, with the loss of the anterior inner cusp, Thus the molars become quadritubercular, and opposite. This is the type of many of the Taxeopoda, including the Quad- rumana and Insectivora as well as the inferior Diplarthra. The higher Taxeopoda (Hyracoidea) and Diplarthra add various com- plexities. Thus the tubercles become flattened and then concave, so as to form Vs in the section produced by wearing, or they are _ Joined by cross-folds, forming various patterns. In the Probos- cidia they become multiplied so as to produce numerous cross- crests. » 1885.| Progressive and Retrogressive. 351 The dentition of some of the Sirenia is like that of some of the Ungulata, especially of the suilline group, while in others the teeth consist of cylinders. In the Cetacea the molars of the old- est (Eocene and Miocene) types are but two-rooted and com- pressed, having much the form of the premolars of other Mam- malia. In existing forms a few have simple conical teeth, while in a considerable number teeth are entirely wanting. A review of the characters of the existing Mammalia as com- pared with those of their extinct ancestors displays a great deal of improvement in many ways, and but few instances of retro- gression. The succession in time of the Monotremata, the Mar- supialia, and the Monodelphia, is a succession of advance in all the characters of the soft parts and the skeleton which define them (see table of classification), As to the monotremes them- selves, it is more than probable that the order has degenerated in some respects in producing the existing types. The history of the Marsupialia is not made out, but the earliest forms of which we know the skeleton, Polymastodon (Cope) of the Lower Eo- cene, is as specialized as the most specialized recent forms. The dentition of the Jurassic forms, Plagiaulax, etc., is quite special- ized also, but not more so than that of the kangaroos. The pre- molars are more specialized, the true molars less specialized than in those animals. Coming to the Monodelphia the increase in the size and com- plication of the brain, both of the cerebellum and the hemi- spheres, is a remarkable evidence of advance. But one retro- gressive line in this respect is known, viz., that of the order Amblypoda} where the brain has become relatively smaller with the passage of time. The successive changes in the structure of the feet are all in one direction, viz., in the reduction of the num- ber of the toes, the elevation of the heel and the creation of tongue and groove joints where plain surfaces has previously existed. The diminution in the number of toes might be re- garded as a degeneracy, but the loss is accompanied by a pro- portional gain in the size of the toes that remain. In every respect the progressive change in the feet is an advance. In the carpus and tarsus we have a gradual rotation of the second row of bones on the first, to the inner side. In the highest and latest orders this process is most complete, and as it results in a more 1See NATURALIST, Jan., 1885, p. 55- 352 On the Evolution of the Vertebrata, etc. [April, perfect mechanical arrangement, the change is clearly an advance. The same progressive improvement is seen in the development of distinct facets in the cubito-carpal articulation, and of a tongue and groove (“intertrochlear crest”) in the elbow-joint. In the vertebre the development of the interlocking zygapophysial artic- ulations is a clear advance. Progress is generally noticeable in the dental structures ; unlike the marsupial line the earliest dentitions are the most simple, and the later the more complex. Some of the types retain the primi- tive tritubercular molars, as the Centetidze, shrews and some lemurs, and many Carnivora, but the quadritubercular and its derivative forms is by far the most common type in the recent fauna. The forms that produced the complicated modifications in the Proboscidia and Diplarthra appeared latest in time, and the most complex genera, Bos and Equus, the latest of all. The extreme sectorial modifications of the tritubercular type, as seen in the Hyznidz and the Felidz, are the latest of their line also. Some cases of degeneracy are, however, apparent in the mono- delphous Mammalia. The loss of pelvis and posterior limbs in the two mutilate orders is clearly a degenerate character, since there can be no doubt but that they have descended from forms with those parts of the skeleton present. The reduction of flex- ibility seen in the limbs of the Sirenia and the loss of this char- acter in the fore limbs of the Cetacea are features of degeneracy for the same reason. The teeth in both orders have undergone degenerate evolution, to extinction in the later and existing forms of the Cetacea. The Edentata appears to have undergone de- generation. This is chiefly apparent in the teeth which are deprived of enamel, and which are wanting from the premaxillary bone. A suborder of the Bunotheria, the Tzniodonta of the Lower Eocene period, display a great reduction of enamel on the molar teeth, so that in much worn examples it appears to be wanting. Its place is taken by an extensive coat of cementum, as is seen in Edentata, and the teeth are ever rootless as in that order. It is probable that the Edentata are the descendants of the Tzniodonta by a process of degeneracy. Local or sporadic cases of degenerate loss of parts are seen in various parts of the mammalian series, such are toothless Mam- malia wherever they occur. Such are cases where the teeth be- come extremely simple, as in the honey-eating marsupial Tarsipes, 1885.] Progress of N. A. Invertebrate Palaontology for 1884. 353 the carnivore Proteles, the Pteropod bats, and the aye-aye. Also where teeth are lost from the series, as in the canine genus Dyso- dus, and in man. The loss of the hallux and pollex without corresponding gain, in various genera, may be regarded in the same light. In conclusion, the progressive may be compared with the retrogressive evolution of the Vertebrata, as follows: In the earlier periods and with the lower forms, retrogressive evolution predominated. In the higher classes progressive evolution has predominated. When we consider the history of the first class of vertebrates, the Tunicata, in this respect, and compare it with that of the last class, the Mammalia, the contrast is very great. :0: PROGRESS OF NORTH AMERICAN INVERTEBRATE PALZZONTOLOGY FOR 1884. BY J. B. MARCOU. * Sale year that has just passed has been fairly prolific in palæ- ontological work, about fifteen more titles appearing in this review than there were in the last; it is true that a few of them should have been inserted last year, but doubtless some titles have escaped me also this year, and the two errors may be con- sidered to compensate each other; so that we have an increase of about one-third in the number of articles published. There is also a general improvement in the quality of illustrations, though of course there is still plenty of room for improvement, and it is surprising.that some paleontologists should persist in publishing a large number of descriptions with no illustrations at all, or with such imperfect illustrations as to render them practically useless ; the chief result brought about by such publication of species is an increase of our already voluminous synonymy. The day will _ doubtless come when descriptions of new species unaccompanied by proper diagnoses and illustrations will no longer be recog- nized, for it is next to impossible to recognize a form from a mea- ger description unaccompanied by an illustration. The founding of new genera and species on very imperfect specimens is also a very reprehensible practice, for although it may be excellent ex- ercise for the imagination of the author, yet it may introduce errors which it will take a great deal of time and trouble to eradi- cate, especially when there is no indication that such descriptions VOL.

This year we have the first volume of the Transactions of the Royal Society of Canada. The committe on publication cannot be too severely criticised for having printed a large quarto of about 700 pages, containing many interesting papers, without any index, and for using five different systems of pagination, as well as varying the system of headings for each page.

Survey, has published his “ Contributions to the knowledge of the older Mesozoic flora of Virginia.” This work is divided into three parts ; in the first the author gives a brief description of the geology of _ the Virginia Mesozoic areas. In the second he describes the flora and compares it with plants from the Triassic, Jurassic and Rheetic of other regions. In the third he republishes Emmons’ figures of the Mesozoic flora of N. Carolina, compares it with the Virginia flora, considers both floras as of the same age, and that age as not older than the rheetic. 1885.] Invertebrate Paleontology for 1884. 355 S. W.

This contains also additions and corrections to the first two parts previously published. In the 13th annual report of the Indiana Department of Geol- ogy and Natural History, the same author publishes “ Principles of Palzozoic Botany,” an excellent elementary treatise. The Indi- ana Geol. Surv. has done excellent work in the way of popular instruction, and it is to be hoped that its labors will not be per- manently discontinued. In the AMERICAN NATURALIST for Sep- tember the author has an article on “ The Carboniferous flora of Rhode Island.” J. B. Marcou, in the American Naturaist for April, pub- lished a review of the progress of North American invertebrate paleontology for 1883. G. F.

J. W. Spencer, in the Bull. Museum of the University of the State of Missouri, publishes an article on “ Niagara fossils,” which will be reproduced also in the Proc. St. Louis Acad.

The illustrations are so bad and the species in some instances, ¢. g., Cyrtoceras reversum, founded apparently on such poor specimens that it will be very difficult if not impossible for future workers to recognize Mr. Spencer’s types. Frank Springer, in the Amer. Journ. Sci. and Arts for February, has an article “ On the occurrence of the Lower Burlington lime- stone in New Mexico. E. O. Ulrich, in the Journ. Cincinnati Soc. Nat.

Walcott has published his “ Palæontology of the Eureka district,” being Vol. vin of the monographs of the U. S. Geolog- ical Survey. The discussion of the development of Olenellus 358 Progress of North American [April, howelli is very interesting. The discovery in the Devonian of the interior of a dorsal valve of Lingula whitei proves the great similarity of structure between the Lingule of the Silurian, Devonian and recent time. A commingling of Upper Devonian and Lower Carboniferous fossils occurs; there occurs also a gradual transition from the beds containing Olenellus howell through beds containing a fauna similar to the Potsdam of New York, to beds containing a fauna comparable to that of the chazy and calciferous groups. The transition is very gradual, and such as would occur where there had been no marked physical dis- turbance. In the Bull. U. S. Geological Survey the same author has “ Preliminary studies on the Cambrian faunas of N. America.” These are in three parts, the first is “ A review of the fauna of the St. John formation, contained in the Hartt collection.” This work is not meant to encroach on that of Mr. Matthew. Mr. Walcott does not accept the genus Conocephalites, and refers its different species to Ptychoparia and one of Conocoryphe. The second part is on the “ Fauna of the Braintree Argillites.” The third part contains the description of a new genus and species of Phyllopoda from the Middle Cambrian slates of Parker’s farm, Georgia, Vermont. In Science, Vol. m1, the same author has an article on the “ Appendages of the Trilobite;” he notes the veri- fication of the hypothesis that the legs were jointed beneath the pygidium as the only addition to our knowledge furnished by Mr. Mickleborough’s specimen, Lester F. Ward, in the Amer. Your. of Sci. and Arts, has an article “ On Mesozoic Dicotyledons.” C. A. White, in the Rep. of the Secretary of the Interior for 1883, Vol. 11, gives “A review of the fossil Ostreidæ, North America, and a comparison of the fossil with the living forms. With appendices by Professor Angelo Heilprin and Mr. John A. Ryder.” This work is on the same plan as that followed in the review of the non-marine fossil Mollusca published the year pre- vious. In the Bull. of the U. S. Geological Survey, No. 4, the author has three articles, the first, “ On a small collection of Me- sozoic fossils collected in Alaska, by Mr. W. H. Dall, of the U. S. Coast Survey.” The author considers these forms to belong to beds occupying a transitional position between Cretaceous and Jurassic, as previously suggested by Professor J. Marcou. The _ second is a “ Description of certain aberrant forms of the Chami- 1885.] Invertebrate Paleontology for 188 4. 359 dz from the Cretaceous rocks of Texas.” And the third is “On the nautiloid genus Enclimatoceras Hyatt, and a description of the type species.” In Vol. vi of the Proc. of the U. S. National Museum he has an article “On the Macrocheilus of Phillips, Plectostylus of Conrad, and Soleniscus of Meek and Worthen. In Science, Vol. 111, he has a note on the “ Enemies and parasites of the oyster, past and present.” In the 13th annual report of the Indiana Department of Geol. and Nat. Hist., the same author has “ The fossils of the Indiana rocks, No. 3.” In this work he gives excellent illustrated descriptions of the characteristic inver- tebrate animal remains of the Carboniferous period. J. F. Whiteaves, in the Geol. and Nat. Hist. Surv. of Canada, has Part 111 of his Mesozoic fossils, “On the fossils of the coal- bearing deposits of the Queen Charlotte islands collected by Dr. G. M. Dawson in 1878. The author is driven by his conclusions to assert that the Jurassic of the Black hills and Rocky mountains is Cretaceous. This assertion is far from being justified by the facts which the author adduces for its support. He has also Part 1 of Vol. 11 of “ Paleozoic fossils.” In the Trans. Royal Soc. Canada, he has an article on the “Lower Cretaceous rocks of British Columbia.” In this article he holds thatthe presence of an abundance of Ancellz is a sure proof of the Neo- comian age of the rocks in which they occur. In the same pub- lication he has also an article “On some supposed Annelid tracts from the Gaspé sandstones.” R. P. Whitfield, in the Bull. Amer. Museum Nat. Hist. Vol. 1, No. 5, has a “ Notice of some new species of primordial fossils in the collections of the museum, and corrections of previously described species.” He thinks that the difference in faunas be- tween the different Cambrian areas is more the result of the con- ditions upon which life depended than a difference in time. H. S. Williams, in the Bull. U. S. Geol. Surv., Vol. No. 3, has an article “ On the fossil faunas of the Upper Devonian along the meridian 76° 30’ from Tompkins county, New York, to Bradford county, Pennsylvania.” The paper is the first of a series. In Science, Vol. 111, he has an article on “ The Spirifers of the Upper Devonian.” H. Woodward, in the Geological Magazine for February and for April, has two articles, one is “On the structure of Trilo- bites.” This is a reproduction of the author’s views on the ap- 360 The Clam-Worm. [April, pendages of trilobite and in particular of Asaphus platycephalus Stokes, as published by him in 1871. The other bears the title, “Notes on the appendages of Trilobites. Note to accompany three woodcuts of Asaphus megistos, a trilobite discovered by Mr. James Pugh, near Oxford, Ohio, in the upper portion of the Hudson River group.” The figures are a reproduction of Mr. Mickleborough’s. ` A. H. Worthen, in Bull. No. 2 of the Illinois State Museum Nat. Hist., publishes descriptions of two new species of Crusta- cea, fifty-one species of Mollusca and three species of Crinoids from the Carboniferous formation of Illinois and adjacent States. No illustrations whatever accompany these numerous descrip- tions. vat THE CLAM-WORM. BY SAMUEL LOCKWOOD, PH.D. wo at low tide on the wet flats of the New Jersey shore, the stranger is surprised by little spurts of water suddenly springing from the sand. These jets reveal the hiding places of the soft clam, or “ nanny nose,” a corruption of the In- dian name “ maninose.” This discharge of water at the approach - of footsteps, thus betraying its retreat, is an act which the mol- lusk cannot help. The home of the bivalve is often many inches deep in the sand, but the extensile siphon must reach the surface. Alarmed at the tremor of the sand caused by the approaching steps, this organ is so rapidly withdrawn, even down into the valves at the bottom of the perpendicular burrow, that the sud- den collapse expels the water with which the siphon and other cavities of the body are filled. Without such result the rapid retreat of the siphon from harm’s way would be impossible. After one of these squirts I have dug fully fourteen inches deep, and found the clam with all its parts snugly tucked within its two valves, The water ejected as described is simply the fluid which was taken in before the tide went out. If the observer will be quiet and keep motionless for a few minutes the clam may soon regain its confidence, and the tip of the siphon, with its two pretty ori- fices—the inlet and the outlet, again appear at the little hole in the sand. Now let one’s foot be moved, and again the siphon is 1885.] The Clam-Worm. 361 instantly withdrawn ; but there is no spurt‘as before, because the previous effort had emptied it of water. The systematists call our mollusk Mya arenaria, but in popu- lar speech, because of its siphon, it is sometimes known as the stem-clam, and to distinguish it from Venus mercenaria, the qua- hog, round-clam or hard-clam, it is often called the soft-clam and long-clam. Busily delving with short-handled hoes, men and boys may be seen, at low tide, all over these sandy flats. They are “ the clam- mers.” Long practice, with perhaps inherited instinct, has made these persons expert in detecting the signs of the places of these mollusks, even when not betrayed in the usual way. They cer- tainly have that fine eye for discernment which comes of being to the business “bred and born.” Though perhaps preferring such places, these soft-clams are not limited to the sandy flats. They are also found in gravelly and even muddy beds. In digging the:clammer brings to the surface many a fine inver- tebrate of much interest to the naturalist. Among these quite often is a gayly tinted annelid, a quasi-aquatic myriopod. We watched one of these delvers,a youth quite bright in his own way, and respectful too, except perhaps to some student pedant whom he cannot understand, and whom he seems to regard as a - “dude in larning,” as we found out a little to our cost. There! He turns up an annelid now, and we exclaim—* What a pretty Nereid!” To which, with a quizzical cast of the eyes, he responds: “ Nary time, Mister! That’s. only a clam-worrum P Glad to become a learner upon opportunity, we ask why it is calleda clam-worm. The answer, now politely given, is: “ Because its gin’ally found along with the clam. » Most like it’s clam-feed, or something in that way.” The best known of these Nereids in our Eastern waters are WV. limbata, N. virens and N. pelagica ; of these three the chances are many that the Jersey clammers’ acquaintance will be restricted to the first one mentioned, though all would be the same to him. And it must be known- that though called a clam-worm, Nereis is no pariah, but the very highest in its class, the Annelides. And N. limbata is sometimes found seeking the higher society of the marine invertebrates. Verrill says of this species: “ Both males and females were often found among the barnacles and ascidians on the piles of the wharves at Wood's Holl, but the males were 362 The Clam-Worm, [April, the most abundant, while the reverse was the case with those dug out of the sand and gravel at the shores.” The same author tells of their habitats in shelly and gravelly beds, and even of their floating in great numbers at the surface of the water. This state- ment recalls a thrilling experience of our own many years ago inside of Sandy Hook. All told we numbered three, in a sail- boat, and our one object, squidding for blue-fish, the gamey Foma- tomus saltatrix. The wind was so stiff that we had enough on our hands to take care of ourselves and our little craft. It was a very warm day in August, and to my astonishment we went through a floating bank of these clam-worms, They lay close together, and the float seemed several hundred feet long, and owing to the high wind it was disposed in concentric drifts, or wind-rows. Our game was up, touch our squids Pomatomus would not—he had come to a banquet worthy of the gods—I cannot affirm whether _ the banquet had attracted them, but just after the Nereid course was finished, a school of Menhaden appeared, The blue-fish went for them, and the scene was simply pitiful. In their frantic efforts to escape, the poor things piled themselves one upon another, and the jaws of the terrible blue-fish, like a thousand shears, cut into them, while the air was alive with gulls screaming in delight over the carnage, as they were continually pouncing upon the floating fragments of the gory feast. As the Nereids deposit their eggs near shore, and as this scene was witnessed in- side of Sandy Hook bay, a good place for their breeding, and as my memory serves, the worms were small, it has seemed to me that they were young individuals. Wishing to resume study of the Actiniz, I procured from Fall river some specimens of Metridium marginatum, with a quan- tity of the green sea-lettuce, Ulva latissima, among which was one tuft of the succulent red alga, Rhabdonia tenera. The plants soon took on a fine growth. I became annoyed, however, at the unsightly appearance of ragged holes in the green fronds, and their number steadily increasing. Soon the depredator was detected at work in a thick bunch of Ulva. The red alga was not touched. This annelid browsing was an interesting sight. For every one of its many segments was a pair of parapoda, or side paddles, with which, though the action seemed serpentine, it moved about a plant as easily as a bird around an evergreen when seeking insects on the tree. And what a pair of jaws, each 1885. ] The Clam-Worm. 363 with a row of small sharp teeth on the curve of the inner side, as if two tiny sickles could be converted into saws. The little beast ` was slashing remorselessly into these translucent delicate sheets of emerald gelatine. I said jaws. The whole apparatus has been called a proboscis—but such an exceptional one! The annelid in repose carries his jaws down his throat just over the cesopha- gus, and when he eats the two serrate sickle jaws are everted, that is, protruded, pharynx and all. This creature was our clam-worm, Nereis limbata. “It moves in graceful ease through the marine meadows by means of its two long rows of parapoda, or natural oars. It has four eyes, and they see me too, for it disappears instantly. Its retreat is a little burrow in the sand, a transverse section of which would be nearly oval. The books say that the Nereis secretes a viscid fluid with which it lines its burrow. - Its progress in this retreat is rapid, and it can move either way with equal ease. Its head is now at the entrance, hence it has turned in its burrow, and as this is pretty well filled by the worm’s body, how does it double on itself? It has such a knowing look with its four optics, and four pairs of feelers, as if in its tentacular wis- dom it were inspecting every object anent the cabin door. And then it has an amiable look, for that proboscis with its formidable jaws is concealed down the throat. I found two others in the tank. Each was from two and a half to three inches long. Twice one of them was so accommodating as to make its burrow against the glass side of the tank. I now watched the movement in the burrow and saw how easily it could advance or recede; but I failed to see the doubling on itself And then it was pretty to note that the paddle-like rami were never soiled. How could I grudge my Nereids their inroads on the lettuce beds, as I deemed them vegetarians of the Simon-pure variety ? I was feeding the Actiniz with small pellets of raw beef. It oc- curred to me to tempt the Nereid from its simple fare with a stronger diet; so I dropped a bit of beef at the entrance to the burrow. The tentacular wisdom made a snap judgment—“ fresh beef is good,” for out popped the proboscis, that is, the pharynx and its formidable jaws, and the welcome morsel was hooked with a jerk into the burrow. How deceptive are appearances. Vege- tarian indeed! My Nereids are rabid carnivores. Thence on I fed the Nereids beef whenever I fed the Actiniz. 364 The Clam-Worm. [April, To the naturalist who uses the microscope, an old marine aquarium is fruitful of interesting minute forms of life, both plants and animals. This is certainly true of the micro-alge. I observed one day what seemed to me a new form of alge, little clusters of a deep orange color on the sandy floor of the aqua- rium. Each bunch was hardly more than an eighth of an inch in diameter. Some of the little cylinders of which a cluster was composed were put under the microscope. There was not the slightest appearance of any cell structure, nor even the presence of any distinct protoplasm. They were granular in composition, but there was no sac or case. They had something of the look, size excepted, of the casts in Bright's disease. These little tufts of tiny orange-colored cylinders kept on increasing. When two or three days old they turned white. I noticed that they were all in proximity to the burrows of the Nereids. They proved to be their excreta—enteric casts of their imperfectly digested food. That deep dull orange was still a puzzle, for when freshly cast these excreta were exactly the color of the calcareous crust which covers the horny axis of some of the sea-fans, Gorgonia. It was noticeable that since the beef diet had been begun, the Ulva was let entirely alone. But there arose a famine in the land. No fresh beef could be got. Of course the Nereids could go back to the sea-lettuce, but they chose to let it alone. From “pickings” they turned to “leavings,” or perhaps more correctly from “ primes” to “ mid- dlings.” Thanks to the gentle Cowper whose Task supplies the word befitting ears polite—every “ stercoraceous heap” was soon eaten'up! Our pretty Nereis, then, has a threefold appetency— since it is by turns a vegetarian, a carnivore, and even an auto- stercophaga ! an eater of its own casts. But such things are found in higher quarters. Dr. Rau, in his _ translation of the Jesuit Baegert, says of certain California tribes now extinct, that in its sgason they almost lived upon the fruit of the pitahaya, and when that gave out they were reduced to short rations. Says the missionary : “In describing the pitahayas I have already stated that they contain a great many small seeds resembling grains of powder. For some reason unknown to me these seeds are not consumed in the Es dca cates but _pass off in an undigested state, and in order to save a them the natives collect during the season of the pitahayas that 1885.] Life and Nature in Southern Labrador. 365 which is discharged from the human body, separate the seeds from it, and roast, grind and eat them, making merry over their loathsome meals, which the Spaniards therefore call the second harvest of the Californians.” See Smithsonian Report, 186s, p. 365. Baegert’s book was published at Mannheim, 1773. :0: LIFE AND NATURE IN SOUTHERN LABRADOR. BY A. S, PACKARD. (Continued from p. 275 March number.) FTER roaming over the island and making pretty full collec- tions of the insects, we paid attention to the marine zodlogy. Shore collecting is not as remunerative in Labrador as on the Maine and Massachusetts coasts. The most noticeable form is the six-rayed starfish (Asteracanthion polaris) which sometimes © measured twenty inches from tip to tip of its opposing rays; its color was a dirty yellowish white, not red as in the common fire- finger, also abundant. The polar starfish is common in Green- land, and is a truly arctic form. The common crab (Cancer irrorata) frequently occurred under stones, but the lobster was neither seen nor heard of; though common on the southern shores of Newfoundland it does not reach north into the Straits of Belle Isle. Among the worms which occurred at low water mark was the Pectinaria. On the New England coast it only occurs in deep water below tide mark, Dredgings were first made at the mouth of Salmon river, a few rods from shore, in some eight fathoms of water in a firm deep mud. The most characteristic shells were gigantic Aphrodite &reenlandica, large cockles (Cardium islandicum), as well as the pelican’s foot (Aporrhais occidentalis), which occurred of good size and in profusion. In the soft mud occurred multitudes of the neat little sand star (Ophioglypha nodosa), Another form dredged on rocky bottom was Cynthia pyriformis, or the sea peach, and large specimens were cast up by the waves on the beach. Every spare day was given to dredging, and having been deeply interested in marine zodlogy by the writings of Gosse, in England, and of Stimpson in this country, and having obtained a good idea of the local marine fauna of Casco bay, in Maine, it- was with no little interest and expectation that we dropped the 366 Life and Nature in Southern Labrador. [April, dredge in arctic waters, and we were not a little delighted with the result of finding so near shore and in such shallow water, forms which off the coast of Maine, in deep water, were rare and usually but half grown. July 25th a party of us rowed up Salmon bay and went a mile up the river. The tide was out and we looked for the fresh- water mussel (Alasmodon arcuata), which is our northernmost species, and inhabits the rivers of Southern Newfoundland. We could find none, although the settlers told us that mussels, clams and “ oysters” were common enough in the river. But some- thing better was discovered. We found traces of genuine Quat- ernary marine sands and clays containing fossils. There were several banks of sand and clay along the edges of the river. In the latter I found Aphrodite groenlandica and Aporrhais occiden- talis, with Buccinum undatum. They had been washed out of the clay into the bed of the river, and were collected at low water. I also dug several inches into the clay bank and found the disinte- grated shells of the Aphrodite, so as to leave no doubt but that the shells were fossils. Down at the mouth of the stream at the head of the bay, on the flats, I found several Buccinum undatum, and quite a number of Aporrhais, young and old, broken and entire. On each side of the river was a terrace of sand and clay, with a thick growth of alders and willows, with the fire-weed (Epilobium angustifolium), the golden rod and a large cruciferous plant common in the mountainous parts of New England; also Comarum palustre, and a Thalictrum. Farther back and mostly lining the banks was a dense growth, impossible to penetrate Save occasionally where there was a break in the thicket of spruce and a birch, perhaps Betula populifolia. Still farther up and away back stretched the bare moss-covered hill tops, the summer resort of deer and caribou. Here we saw a ptarmigan. But this was one of our halcyon days, of which there were few, as the last two weeks of July were stormy and wet. The clear fair- weather winds were from the south-west; the south-east winds brought in the fog and rain, while the northerly winds brought a few curlew, the advance guard of the hosts which were to arrive early in August. _ The 3d of August was a fine day. A party of us went up the Esquimaux river to Mrs. Chevalier’s, whose husband, now dead, entertained Audubon when visiting this coast. The sail up the 1885.] . Life and Nature in Southern Labrador. 367 river was a pleasant one. It was about three miles from its mouth to an expansion of the river, on whose shores were four or five winter houses. Although most of the settlers live on the coast through the year, some have their winter and summer houses. Those who live up the interior, sometimes a distance of seventy miles from the coast, where there is wood and game, move from the shore about the 20th of October. They spend a month in cutting wood, a family burning through the winter about thirty cords. Then succeeds a month of hunting and trap- ping. The snow does not come, we were told, until the last of December, although we should judge this to be an extreme state- ment, and the snow is not usually more than three feet deep. The people profess to like the winter better than the summer. They shoot deer, foxes, &c., black fox being sometimes secured, whose skin is worth between two and three hundred dollars. Grouse are abundant, a good hunter securing from sixty to sev- enty a day in favorable seasons. At any rate fresh meat is ob- tained for each family two or three times a week. The houses are small, built of wood, boarded and shingled, seldom constructed of logs, and are heated by peculiar stoves, great square structures resembling Dutch stoves, and heating the whole house, the two living rooms opening into each other, the stove being placed partly in each. The French residents at the Mecatina islands, more social and gayer than the phlegmatic English settlers about the mouth of the Esquimaux and Salmon rivers, spend the winter evening in dancing and other gayeties to which the Anglo-Saxon, in Labra- dor at least, is a comparative stranger. The Esquimaux river at its eastern entrance is but a few rods ` wide. Passing Esquimaux island we sailed out into a broad bay or expansion of the river, with ravines leading down to it, and under the steep bank protected from the northerly winds were the winter houses previously described. Up the river, just beyond Mrs. Chevalier’s, the river contracted into narrows with rapids ; it then opened into another bay or expansion two miles wide, the river being a succession of lakes connected by rapids, and this is typical of the rivers and streams of the Labrador peninsula. A barge cannot sail up the Esquimaux river more than fifteen miles, although one can push farther on in a flat boat. We were told that the river is about two hundred miles in length, and although perhaps the largest in Labrador it has never been explored. 368 Life and Nature in Southern Labrador. [ April, Here we met the black flies in full force, and although we had been fearfully annoyed by them in rambling over Caribou island, here they were astounding, both for numbers and voracity. The black fly lives during its early stages in running water. The in- sect finds nowhere in the world such favorable conditions for its increase as in Labrador, over a third of whose surface is given up to ponds and streams. The insides of the windows of Mrs. Chevalier’s house swarmed with these fiends, the children’s faces and necks were exanthematous with their bites; the very dogs, great shaggy Newfoundlanders, would run howling into the water and lie down out of their reach, only their noses above the sur- face. The armies of black flies were supported by light brigades of mosquitoes. No wonder that these entomological pests are a perfect barrier to inland travel; that few people live during sum- mer away from the sweep of the high winds and dwell on the ex- posed shores of the coast to escape these torments. They are effectual estoppers to inland exploration and settlement. Accepting our hostess’ kind invitation to take dinner, we sat down to a characteristic Labrador midday meal of dough balls swimming in a deep pot of grease with lumps of salt pork, with- out even potatoes or any dessert; nor did there seem to be any fresh fish. The staples are bread and salt pork; the luxuries game and fish; the delicacies an occasional mess of potatoes, brought down the St. Lawrence once a year in Fortin’s trading schooner. Over the mantelpiece was a stuffed Canada grouse or partridge and a ptarmigan in its winter plumage, but I was most delighted with the gift of some Quaternary fossils with which Mrs. Cheva- lier kindly presented me, including large specimens of Cardita borealis, Aporrhais occidentalis and, most valuable of all, the valves of a brachiopod shell, which I had also dredged on the coast in ten fathoms, the Hypothyris psittacea. On our return down the river we fished up the valves of the Pecten magellant- cus, the great scollop shell, which lives in five or six feet of water. This mollusk, which is locally known in Labrador by the name of “ pussel,” we afterwards obtained in quantity, fried it in butter and meal, finding it to be delicious eating, combining the prop- erties of the clam and oyster, the single large adductor muscle being far more tender than that of the c common scollop of South- ern New acne and New York. 1885.] Life and Nature in Southern Labrador. 369 With our man, James Mosier, and his sailboat we spent two days in dredging in from forty to fifty fathoms out in the Straits of Belle Isle, three or four miles from land. The collection was a valuable one, containing some new species. The crown of the bank which we raked with our poorly constructed dredge was packed with starfish, polyzoans, ascidians, shells, worms and Crustacea. .The collection was purely arctic, and had not the only dredge I had become broken, we should have reaped, or rather dredged, a rich harvest. As it was, the novelties were quite numerous, and the interest and excitement, as well as labor, of overhauling, sorting and preserving what we did obtain lasted for several days. The only plant besides stony vegetable growths called “ nulli- pores” dredged at this depth was a delicate red sea-weed, the Ptilota elegans, which was found afterwards to extend as far down in depth as ninety fathoms. Those who glibly talk, on zerra firma, of plant life as affording a basis for animal life, should dredge in deep water. They will find that a vast population of animals of all sorts and conditions in the scale of life is spread at all depths over the sea bottom, thriving almost without exception on one another—on animal protoplasm—and in the beginning of creation animal life was without doubt contemporaneous in ap- pearance with vegetable existence. Indeed, what is the differ- ence in form and structure bétween a bacterium and a moner ? The two worlds of plant and animal life arise from the same base, a common foundation of simplest structure, showing none of the distinctive characteristics of animal or plant life, and only barely earning the right to be called organisms, that vague term we apply for convenience to any, even the simplest structures en- dowed with life. Of all the pleasures ot a naturalist’s existence, dredging has _ been, to our mind, the most intense. The severe exertion, the swimming brain, the qualms of sea sickness, tired arms and a broken back, the memory of all these fade away at the sight of the new world of life, or at least the samples of such a world, which lie wriggling and sprawling on the deck of the sailboat, or sink out of sight in the mud and ooze of the dredge, to be brought to light by vigorous dashes of water drawn in over the side of the boat. Those days of dredging on the Labrador coast, where there was such an abundance and luxuriance of VOL. XIX.—NO. IV. 24 370 Life and Nature in Southern Labrador. [ April, arctic varieties, were days never to be forgotten. There is a nameless charm, to our mind, in everything pertaining to the far north, the arctic world, and we can easily appreciate the fasci- nation which leads one back again to the polar regions, even if hunger and frost had once threatened life. Arctic exploration has but begun, and though its victims will yet be numbered by the score, enthusiasts will yet attempt the dangers of arctic nav- igation, and fresh trophies will yet be won. Early in August, during the few still clear nights succeeding bright and pleasant days, we had auroras of wondrous beauty, not excelled by any depicted by arctic voyagers. On the roth of August the curlews appeared in great numbers. On that day we saw a flock which must have been a mile long and nearly as broad; there must have been in that flock four or five thousand! The sum total of their notes sounded at times like the wind whistling through the ropes of a thousand-ton ves- sel; at others the sound seemed like the jingling of multitudes of sleigh bells. The flock soon after appearing would subdivide into squadrons and smaller assemblies, scattering over the island and feeding on the curlew berries now ripe. The small snipe- like birds also appeared in flocks. The cloud berry was now ripe and supplied dainty tid-bits to these birds. By the 18th of the month the golden rods were in flower. Here, as has been noticed in arctic regions, few bees and wasps visit the flowers; the great majority of insect visitors are flies (Muscidz), especially the flesh fly and allied forms. A bumble- bee occasionally presents himself, more rarely a wasp, with an occasional ichneumon fly, but the two-winged flies, and those of not many species, were constant visitors to the August flowers. The black flies still remained to this date terrible scourges in calm weather, though in cloudy days and at night they mostly disappeared. : Wandering through the fog and drizzle along the mud flats on the northern side of the island I picked up Aporrhais occidentalis, Fusus tornatus, Cardita borealis, large valves of Saxicava rugosa, Buccinum and Astarte sulcata and compressa; these and Pecten us and other shells forming much the same assemblage as Thad dredged a few days previous out in the straits in fifty fath- _oms. The only recent shells lying about were shallow-water forms, such as the common clam, Ze/lina fusca and the razor 1885.] Life and Nature in Southern Labrador. 371 shell. It was evident that here was a raised sea-bottom, and the Quaternary formation. In the afternoon I returned to the spot and dug up many more shells mingled with pieces of a yellow limestone containing Silurian fossils, brachiopods and corals. This horizon, then, represented a deep sea-bottom, over which the open sea must have stood at least 300 feet, while the clay fossils of the mouth of the Esquimaux river must have lived in a deep muddy bay sheltered from the waves and currents of the open sea. The drift deposits of Labrador are scanty in extent compared with those of the Maine coast. They are but isolated patches compared with the extensive beds of sand and clay which compose the Quaternary deposits of New England. On the 22d August we made our last excursion up the Esqui- maux river, going up some six miles from its mouth. Froma hill top I could look over the surface of this lake-dotted land. The surface was rugged and bare in the extreme. The river val- ley, however, was well wooded, the spruce and birch perhaps thirty feet in height. Here and there the river passed through high precipitous banks of sand. The hills were rough, scarred with ravines, precipices, and deep gaps, the syenite wearing into irregularly hummocky hills, the rough places not filled up with drift, and thus the contours tamed down as in New Eng- land. Indeed, Labrador at the present day is like New England at the close of the ice period or at the beginning of the epoch of great rivers, before the terraces were laid down and the country adapted for man’s residence. Labrador was never adapted for any except scattered nomad tribes. It is still an unfinished land. While the hills were bare and the rocks covered with the rein- deer moss, here and there by the river’s edge in favorable, pro- tected places were tall alders and willows, with groups of asters and golden rods. Here I saw a veritable toad, and glad enough was I to recognize his lineaments. I was also told that there were frogs in existence, though we ‘never saw or heard them. There are no snakes or lizards, so that our history of these ani- mals in Labrador will be as brief as that of the Irish historian, but we did find a small salamander at Belles Amours in a later trip to this coast. On our return we found that a whaler had towed a sab into the month of the river and was about to try out the oil. We secured a piece of the flesh, and on reaching camp boiled it; it e Den of the Tertiary formation of the West. Book I. 372 Recent Literature. [April, was not bad eating, tasting like coarse beef. Seal’s flippers we also found not to be distasteful, though never to be regarded as a delicacy. Dredging and collecting insects on fine days when not too calm filled up the measure of our seven weeks. The time passed rapidly, the days were too short for all the work we planned to do, and it was not without regret that we left the rugged un- tamed shores of the Labrador. On the afternoon of the very day she had set for her return to Caribou island, the Nautilus hove in sight. As she made our harbor she struck upon a sunken rock, tore off a piece of her keel, but slid off and came to anchor as near as practicable to the mission house, and then succeeded the mutual spinning of Labrador and Greenland yarns by the reunited party. ‘oO: RECENT LITERATURE. Copr’s VERTEBRATA OF THE TERTIARY FORMATIONS OF THE West.\—Just ten years ago (1875) a bulky quarto volume on the Vertebrata of the Cretaceous formation of the West, by Professor Cope, appeared, forming the second volume of the memoirs of the Hayden Geological Survey of the Territories. The ponder- ous volume now before us contains between three and four times as many- pages and about fifty more plates. The work is de- signed to present figures and descriptions of the vast number of species of vertebrates of all classes, but more especially of the mammals of the Tertiary lake-basins of the West. For the first time the palzontologist has before him the materials for a view of that rich fauna which through the Tertiary period crowded the shores of the immense lakes whose sediments form the surface ‘of our Western plains—a fauna whose descendants, vastly less in number though more highly specialized, still survive on this con- tinent. The subject is naturally the most attractive the palzeontologist could have presented to him, since the materials represent a num- ber of extinct orders, suborders and families, which fill more or less completely the wide gaps between the existing orders of mammals, and enable the student to examine the foundations, so to speak, upon which the existing groups have been built up; this, of course, has led not only to the solution of knotty points _ in classification, but to broader conceptions of the relations of the MATES.

[ April, Some typographical errors are not corrected in the errata, this is probably due to the fact that the printing was done mostly during the summer while the author was in the field, while a large amount of proof was sent to Mexico and there lost. The present volume is divided into two parts, Part 1 relating to the Puerco, Wasatch and Bridger faune (Eocene); and Part 1 comprising the White River and John Day faunz, Lower and Middle Miocene. Vol. 1v is in preparation and will comprise the Upper Miocene fauna (Ticholeptus and Loup Fork fauna) and the Pliocene. The introduction is divided into two sections, in the first of which the character and distributions of the Tertiary formations of the central region of the United States are noticed, In the second section are discussed the horizontal relations of the orth American Tertiaries with those of Europe. Then follow the description of the fossils, beginning with the fishes and ending with the mammals. The general conclusions as to affinities and phylogeny are appearing in the NATURALIST in a series of articles which began two years ago. The work is richly illustrated, the details amply supplementing the descriptions. As the result of extended investigations by an experienced comparative anatomist and morphologist, as well as palzontologist, this and the preceding volumes mark an epoch in American paleontology.

This work, somewhat cut down in size, is the original of the present one. As it is, the first part is a bulky octavo, and, as when completed it will be in two volumes, the book will not be so easy of reference as if it formed a single volume. The boo in its English dress is richly illustrated, the cuts, for the most part, carefully prepared, mostly selected by Dr. Claus himself. To the general part are devoted 179 pages; the usual subjects of organic and inorganic bodies, animals and plants, cells and tissues, correlation of organs, accounts of the different organs, intelli- gence and instinct, development and evolution receiving full and accurate treatment, though the author’s style is at times heavy and prolix, the translators not always adding perspicuity or ele- gance to the cumbrous German expressions.

I the ordinary student will stand aghast at the following sen- tence: “The matter of unorganized bodies (for instance of crys- tals) is in a state of stable equilibrium, while through the organ- ized being a stream of matter takes place.’ Do not streams generally flow? The punctuation is also defective, and cases of tautology occur. Why at this date there should be any distinc- tion, even if in words, expressed between sarcode and protoplasm we do not understand. p. 21 we find the following sentences in the section on the difference between animals and plants: “In the place of muscles, which as a special tissue are absent in the lower animals, there is present an undifferentiated albuminous substance known as sarcode, the contractile matrix of the body. The viscous contents of vegetable cells, known as protoplasm, possesses likewise the power of contractility, and resembles sar- code in its most essential properties.” There is vegetable and animal protoplasm, but why give different names to what is fun- damentally the same substance? Throughout the succeeding pages the word protoplasm is used for the contents of animal cells, and we read no more of sarcode. The translator has, on p. 70, referred to the “ spiral thread” of an insect’s trachea, sufficient liberty might have been taken with the original to have given the latest and most correct view as to the structure of the trachea and the mode of tracheal respiration, pears, but the excellence of the majority of the figures and the judg- 376 " Recent Litevative. [April, ment shown in their selection are almost beyond criticism. Why the Gephyrea and the Hirudinea are placed above the more highly specialized Chztopod worms we do not understand. As also why the Phyllopods should be placed at the base of the Crustacea, below the Copepoda and barnacles. This classification has been strenuously advocated by Claus, but not, we suppose, generally accepted; the reasons militating against this view are many and urgent; the Branchipodide, with their stalked eyes and highly specialized bodies, appear to stand nearer the stalked- eyed Crustacea than any other Entomostraca ; and to go directly from the root-barnacles to the Malacostraca is straining more than one point in taxonomy. In treating the trilobites no reference whatever fs made to American work, especially that of Walcott, who has demonstrated that they had hard jointed limbs; Claus states the obsolete view that they were “ soft and delicate.” Among the Myriopods Pauropus is assigned to the Polydes- midz, when it certainly represents a distinct suborder if not order. The Physopoda or Thrips are regarded as a tribe of Pseudo-neuroptera, although embryology shows they are Hem- iptera. The taxonomy of the Lepidoptera seems to us to be very objectionable and old-fashioned, while it is a comfort to see that e Hymenoptera are placed at the head of the insect series. We shall look with great interest to the appearance of the second, closing volume. Goopa.e’s Puystotocicat Borany..—In the year 1879 Dr. Gray brought out the new (sixth) edition of his widely known . and used Botanical Text-book. The new book covered much less ground than the older editions, being confined to the structural botany of the phanerogams. It was then announced that Dr. Goodale was to prepare a second volume to be devoted to physio- logical botany, Dr. Farlow a third devoted to cryptogamic bot- any, and that the series was to be completed by a fourth volume to include a sketch of the natural orders of phanerogams. After waiting six years we have the pleasure of perusing advance sheets of the long-promised Vol. 1. The part before us is de- voted to the histology of the phanerogams, and is soon to be fol- lowed by Part 11, which is to deal with vegetable physiology. Upon opening the book we have first an interesting chapter devoted to histological appliances ; a most useful chapter indeed it will prove to all workers in the botanical laboratory. In this we observe with pleasure the remark that “other things being equal, a microscope with a short tube and with a low stand will be most convenient on account of the large number of cases in which 1 Gray’: Botanical Text-book {sixth edition).

Here it is encouraging to note that the author still holds to the view that the cell is the unit in vegetable anatomy. The most interesting portion of this chapter is that devoted to plastids (including chlorophyll), protein granules and starch. In chapter 1 the modifications of cells, and.the ttssues they compose, are taken up. The provisional classification adopted is as follows : I, Cells of the fundamental system, or PARENCHYMA cells—permanent typical cells. 1, Parenchyma cells, strictly so-called, including as modifications collenchyma celis and sclerotic parenchyma cells, or grit cells, such as the lignified cells of seed-coats and drupes, etc. 2. Epidermal cells and their modifications, e. g., trichomes. 3. Cork cells, forming suberous parenchyma, or cork. II. Cells and modified cells of the fibro-vascular system—PROSENCHYMA in the widest sense. I. Cells of prosenchyma proper. a. Typical wood-cells and woody fibers, including libriform cells and the secondary wood-cells. 6. Vasiform wood-cells or tracheids. 2. Vessels or ducts. a. Dotted. b. Spirally marked. c. Annular, d. Reticulated. e. cular. x : 3. Bast-cells, bast-fibers or liber-fibers. III. Sreve-cexts, or cirhose cells. IV. LATEX-CELLS. It will be observed that four principal kinds of cells are here recognized, implying four kinds of tissues. Parenchyma is made to include collenchyma and short-celled sclerenchyma, and pro- senchyma likewise includes fibrous cells as well as vessels (trach- We shall reserve the discussion of some points in the chapters before us until after the appearance of part second, but in the 378 Recent Literature, [April, meantime must congratulate the botanical fraternity of this coun- try upon the appearance of this profound and still clearly written work.—Charles E.

Smiru’s DISEASES OF FIELD AND GARDEN Crops.'—In this com- pact little volume the author has brought together the notes of a course of lectures given at the request of the officers of the In- stitute of. Agriculture at the British Museum, South Kensington. It was the endeavor of the author, we are informed in the intro- duction, to keep three objects clearly in view, viz., “ first, the de- scription only of such diseases as are of economic importance ; second, the definition of all the phenomena of the diseases in familiar words, such as, with proper attention, may be understood y all; this has been done without sacrificing scientific accuracy, as all botanical terms in common use are adverted to and ex- plained ; ¢hird, the consideration of the best means of preventing the attacks of plant diseases.” An examination of the book warrants us in saying that the author has succeeded admirably in his attempt. Every progres- sive farmer and gardener ought to procure this book and give it a careful reading. While thus commending this book as a most excellent one in plan and purpose, we need not accept all the author’s views. But this will not necessarily lessen the value of the work for those for whose benefit it was designed —Charles E. Bessey. RECENT BOOKS AND PAMPHLETS, Cope, E. D., and Wortman, J.

GEOGRAPHY AND TRAVELS.’ Asta.—The Island of Formosa.—A paper recently read by Mr. M. Beazeley, before the Royal Geographical Society, gave much information about this little-known island, and elicited more from other members. The Chinese do not seem to have been ac- quainted with the island until 1403, although it is distinctly visi- ble from the mainland and islands of the Chinese coast. So lit- tle did the Chinese emperors know or care about it, that in 1624 they ceded it to the Dutch in exchange for the small group of the Pescadores. Previously to this the Spanish and Portuguese had traded there, and it is supposed that the curious red brick fort at Tamsui, now the British consulate, was built by the Span- iards in the 16th century. The Dutch drove the Japanese from Anping, fortified themselves in Fort Zelandia, and held the island until they were driven out by the celebrated piratical chieftain, Ching Ching-kung, whose grandson handed the island over to the Chinese government, and received his pardon. Formosa strait, between the island and the mainland, is 245 miles wide at its southern end, but only 6214 at its northern end. The island is 245 miles in greatest length, and 76 in greatest width, and is computed to contain 14,982 square miles. A range of mountains, averaging about 12,000 feet in height, extends down the center of the island for the greater part of its length. The ridge of this range is extremely level, though heights vary- ing from 11,300 to 12,850 feet have been made out. Mr. Beazeley declares them to be wooded to the very top, but Mr. Barber states that he has seen snow on the northern parts of the range late in June. There are now no good harbors in Formosa, owing to the fact that the island is rising at- quite a perceptible rate. During the Dutch occupation in the 17th century the capital, Taiwanfu, was a port, Fort Zealandia was an island far out to sea, and an extensive harbor and bay separated the two. This is now a level plain of many miles in extent, and passengers are landed in cata- marans at Anping, under the ruins of the old fort. Anping is merely an open roadstead with no shelter in the south-west mon- soon, during which no vessels visit it. Tamsui, in the north, is at the mouth of a river, with only 114 fathoms on the bar, and 2% fathoms inside, with bad holding-ground. Kelung, also in the north, is very small and much exposed during the north- east monsoon. Takow, in the south-west, twenty-four miles south of Anping, has a shifting bar and a very narrow entrance, : = while only the outer end of the lagoon affords anchorage. There -BE s a small harbor at Sao bay on the east coast. The neighboring small group of the Pescadores has two fine harbors, Ponghou and Makung, and it would be absolutely necessary for any foreign + This department is edited by W. N. LOCKINGTON, Philadelphia. 1885. | Geography and Travels. 381 power that wished to hold Formosa to possess these harbors. At present Amoy is practically the port of Formosa, and the produce of the island is sent thither in small vessels. There are no active volcanoes in the island, but there are signs of volcanic action in boiling springs, etc., and earthquakes are frequent. When Mr. Beazeley accompanied a party in 1875 to select a site for a lighthouse at the South cape, Chinese authority had not extended so far as it now has, and it was not without much difficulty and some danger that the travelers made their way from Takow to the cape. The Chinese inhabitants of the country are described as apparently well-to-do, the villages clean and the chil- dren, who are mostly naked, healthy and strong. The mangoes grown in Formosa closely resemble the Bombay mango in ap- pearance and flavor, and the pineapples are without a crown of leaves. The aborigines are much darker and more muscular than the Chinese, wear nothing but a scanty blue cloth round the waist, and are armed with bows and arrows and long knives, Many carry matchlocks. In shape Formosa has been compared to a cleaver with a short handle, or to a fish, the tail or handle being the narrow part just north of the South cape. It is cer- tainly one of the most beautiful and fertile spots on the face of the earth. Northern Afghanistan —The northern part of Afghanistan is watered by the Heri-rud, Murghab and affluents of the Amu- Daria, and thus belongs to the Aralo-Caspian basin. The Af- ghans do not extend beyond the mountains (Hindoo Koosh, Parapomisus, etc.) except in the north-west at Herat, though they hold in military subjection the Mongol tribes of the lowland areas. The Hazareh, etc. (Mongolian) of the mountains east and south-east of Herat are independent, and the region between the Murghab and Heri-rud is occupied by Turkoman tribes, among whom are about 30,000 who have recently come southward from Merv. Eastward of these Turanian tribes are various peoples of Iranian race, some of whom are thought to be the aboriginal inhabitants of this mountain land—the supposed cradle of the Aryan stock. Among these are the Black Kafirs or Siah-posh, who alone of these tribes have not embraced Mohammedanism, who use tables and chairs and into whose country an Afghan dare not penetrate. North of these are the Badakshi. The Russians claim that the Hindoo Koosh forms the northern limit of Afghanistan, but north of this line, at its eastern extremity, Aryan tribes extend even to Darwaz and Karateghin Hsi-Fans, or tributary aboriginal tribes of Thibetan race which live scattered along the Thibetan border of China from Yunnan to Kan-su, are now in Pekin. The Hsi-Fans are short, fond of red clothing, and adopt Chinese fashions in no small degree. Their faces are rounder than those of the Chinese, their heads 382 General Notes. [ April, smaller, their noses less stunted, small and pointed. Their eyes are small, placed in a line, and have a bright black luster. Quiet though they are now, history shows that they struggled manfully against the Chinese. The Lolos of Sze-Chuan are allied to the Burmese, and seem to form a nation. Both they and the Hsi- Fans belong to the Eastern Himalaic, while the rest of the abo- riginal tribes in Western China and in the southern provinces, whether Miao, Rao or Tung, seem to belong to the Eastern Him- alaic, the branch to which belong the Siamese, Shans, Laos, the Li of Hainan, the Cambodians and the Anamese.——- Dr. Grishimailo’s travels in Ferghana and the Altai have resulted in large geologi- cal and entomological collections, as well as in much anthropo- logical matter. Many evidences of the existence of a glacial epoch in Central Asia were met with, amongst them the presence in Thian-shan of forms which have hitherto only been found in Labrador, Greenland, Lapland and the Swiss Alps. M. Ed. Cotteau has ascended several of the Javan volcanoes, viz., Mt. Cheda, 9844 feet; Mt. Merapi, 9459 feet; Mt. Bromo, 8203 feet, and still active; and Mt.Smeru, 12,469 feet high, the culminating peak of Java. M. Cotteau states that to one accustomed to Swiss mountain-climbing the ascent of these volcanoes is child’s play. AFrica.—A/rican Notes—M. Dolisie, a member of the Brazza mission, has traveled from Loango to Brazzaville. The “ king” of the country gave to the traveler an excellent piece of ground at the confluence of the Ludima with the Kuilu, and had signed a treaty placing all the country between the Ludima and the- Niari under the protectorate of France. This prince and all his chiefs also signed a solemn declaration that they had never ceded any of their rights to the International Society, which did not even own the land on which their stations were built. The route was preferable to that of the Congo and even to that of the Ogowé. th the entrances of this route on the coast of Loango and its termination at Brazzaville are in the hands of France. M. Giraud has again been unsuccessful in his attempt to continue his explorations, having been abandoned by his porters and his escort——The French have the command of the Niger from Bourré to Boussa, some 700 leagues of watercourse. From the north of Africa a French railway runs from Arzen to Méche- ria, and ina few years will be extended to Imsalah, which is al- ready connected with Timbuctoo by caravan routes. The latter will become more important under French protection. The French will certainly also push from Porto Novo on the Gulf of Guinea to Boussa on the Niger, and thus complete their commu- nication between the Mediterranean and the Gulf of Guinea. age of the French navy, has recently explored the valley of the Faléme, one of the most considerable affluents of the Sene- gal.

Small canoes ascend it even now, and it could easily be made accessible to small steamers, since it has neither falls nor rapids, Life is intense throughout the valley, the vegetation for from one to three hundred meters on each bank is so thick that it was only at intervals that our traveler could approach the river; elephants, lions, buffaloes, antelopes, etc., as well as birds abound, and numerous villages are situated within a few kilometers of its course. Gold is found in its sands. Leaving Podor June 24, 1883, he left the Faléme at Senondébau, an abandoned French fort, and proceeded thence to Dialafara, the capital of Tambura, a couutry rich in cattle and gold, and induced the sovereign to sign a treaty of protectorate. From Dialafara Dr. Colin went to Kas- sama, capital of Diébedugu, a city before unknown to Euro- peans. Kassama seemed so important that Dr. Colin endeavored to find a practicable route from thence to the terminus of the French railway at Bafulabé, but failed. M. Tomezek, the com- panion of M. Rogovinski in the exploration of the Cameroons re- gion, died at Mondoleh, May 10, 1884, aged 24 years. Notwith- Standing his youth, he had got together a vocabulary of the Kruman language, explored the Rio del Rey, and taken many notes upon the country. Not only M. Rogovinski, but M. Passavant of Basle, has resolved to advance into the interior of the Cameroons region in search of the mysterious Lake Liba. In his last journey Mr. Stanley ascended the Aruwimi to Tambuga, 2° 43’ N. lat. At that point the river is called Biyere, farther on it is the Berre and the Werré, and Mr. Stanley believes it to be identical with the Welle of the south of the Soudan. He dis- covered on this journey the Lulemgu, an important affluent upon the right bank, and established a station upon the island of Wana- usani, near the right bank of the river, in 0° 10’ N. lat. America.—Worse and Portuguese Colonies in North America — Mr. R. G. Haliburton (Proc. Roy. Geog. Society, January, 1885) identifies the “ Vinland the Good” of Eric the Red with New- foundland. The length of the day given in the Greenland Saga coincides with that of Newfoundland, and the man who called his first find Greenland in order to attract colonists, would not scruple to give a good name to the land found by his son, Leif. Wild grapes are said to occur on the west coast, and this was enough for Eric to magnify into shiploads of grapes and a semi- tropical winter climate. The Helluland of the Saga is, by Mr. Haliburton identified with Labrador, the southern part of which was Markland, while Genunga gap was Belle Isle strait. It was not known until the publication, in 1883, of “ Os Corte Raes,’ by Senhor Ernesto do Canto, that from 1500 to 1579 oe or ak were regularly issued to the Corte Reals as governors of terra Nova, and that at least three settlements were made by the Por- tuguese. Except, perhaps, the Vinland of the Norsemen, this colony, which included Labrador, Newfoundland, Nova Scotia 384 General Notes. [April, and probably a large portion of the east coast of the United States, was by far the oldest European colony in the new world, since the date 1500 is but two years after the discovery of Amer- ica by Columbus and six years after its discovery by Cabot. In 1500 Gaspar Corte Real explored Labrador, probably nearly to Hudson strait, and also Newfoundland and Nova Scotia. In 1521 Fagundes obtained a grant of the country between the land of the Corte Reals (Newfoundland) and the Spanish colonies, and a settle- ment was made at Cape Breton. Traditions of this settlement exist among the Micmacs, who aver that certain earth-mounds at St. Peter’s, Cape Breton, were made by white men before the French came. An archaic cannon, formed of bars of iron, was found many years ago, and an inquiry into the date of the manufacture of such guns showed that it must have been made between 1500 and 1545. Terra Nova was not actually settled, but the fisheries were actively prosecuted. The fate of this colony is not known, but in 1567 a Portuguese settlement was made at Inganish, Cape ` reton. In 1580 the annexation of Portugal to Spain brought the region under Spanish authority, and a colony was sent out which appears to have had a melanchcly end, since our only account of it is that the French convicts left on Sable island in 1598 built barracks to protect themselves out of the wrecks of the Spanish vessels, The name of “ Spanish Harbor” is all that marks their passage. Few persons imagine that the Bay of Fundy is “ Baya Fonda,’ the deep bay, and that Cape Race is “ Cabo Raso,” or bare cape, names given by the Portuguese. Source of the Mississippi—The true source of the Mississippi was found by Captain Glazier to be in a lake in lat. 47° 13’ 25”, and situated three feet above Lake Itasca, the hitherto supposed source of the river.

The latter is as wide as long in the type, and a little nar- rower in a second specimen. Ft supports four tubercles on the inner side; outer side worn.

The crowns are surrounded by a cingulum, except on the inner side, where distinct traces of it are visible. The external cusps are small and low and flattened on the external side, and are connected at their bases by a low ridge. They send inwards each an angular ridge which unites with its fellow in an angular internal cusp of little elevation, en- closing a triangular fossa. Small angular intermediate tubercles exist at the internal bases of the external cusps. The posterior cingulum is a little better developed than the anterior, and rises VOL.

The entire crown is surrounded by a well developed cingulum, which is especially prominent round the external anterior cusp of the second and third true molars. The posterior external cusp of the last true molar is rudimental, and is situated well within the external line om the posterior border. The fourth premolar has a single external cusp, and the cingulum is wanting on the anterior and interior sides. The outline of the base of the crown of this tooth is subtriangu- lar; that of the first and second true molars is a half ellipse ; while that of the last true molar is a transverse oval as in the two species mentioned above.

A BAROMETER FOR MEASURING SEPARATELY THE WEIGHT AND PRESSURE OF THE AIR.—The present mercurial barometer at all times measures, not alone the weight or pressure of the air, but both weight and pressure. It cannot measure either separately, that is, we cannot now when either pressure or weight alone has affected it. It is the purpose of this article to suggest a barome- ter that will measure alone the weight of the air and not be at all influenced by pressure, temperature, moisture or the sun’s or (from the sphere) is inserted a screw, G, with threads measuring one hundredth of an inch, with a large circular head, Æ, gradu- into divisions of one-tenth of its outside circumference, 388 General Notes.

The screw, G, might be made to carry a vernier along the valance bar, c, to register the number of turns of the screw, but such is not shown in this sketch. O is a handle for carrying the box y mm are fulcrums on which a spring bow, o o, rests. 1885.] Geology and Paleontology. 389 On the ends of this bow are two clamps, Z L, for holding and steadying the sphere, B, when being moved or carried from place to place. The clamp screw, J, is turned so as to draw downward the bow, o o, between the fulcrums, 7 m, which causes the upper ends of the bow to clamp the sphere. Four clamps may be used. I think it will be plain to any one that the presence of the air, or the attraction of the earth, sun or moon will be equally exerted on the sphere, B, and the balancing weight (screw G). Also, _ that the difference in the weight of the sphere, 4, before the air is exhausted and afterward, is the weight of the air exhausted. Also, that the difference in the turn of the screw, G, from its position at sea-level, and any tried elevation above, to balance the sphere, is the comparative weight of the air at the two places. If experience should prove that the accumulation of dust and moisture on the sphere, B, will materially affect the weight thereof, it can be obviated by balancing the sphere, B, with an- other of the same surface and weight (exhausted air excepted), which can be moved to the right or left on the left end of the balance beam, c, by means of a screw similar to G, and have the number of turns recorded by a vernier on the balance beam. I have seen the mercurial barometer affected by the sudden opening or closing of a door in a tight room where the barome- ter was hung. I think I was not mistaken when I thought I saw it vibrate with the sudden dashing March winds which are strong enough sometimes to stagger a man as he walks. The plan I suggest will not be affected by these conditions if kept out of the wind current. It will be interesting to compare its action with the mercurial barometer anyway.— no. T.

Tue ERIBOLL CRYSTALLINE Rocks, — Nature contains two lengthy articles upon the crystalline rocks of the Scottish high- lands, the one from the pen of Archibald Geikie, the other a report by B. N. Peach and John Horne. It appears a fresh ele- ment of difficulty has been introduced into the geology of the Highlands. The crystalline schists which in Northwest Suther- land overlie fossiliferous Silurian strata, and which were believed companied by “thrust-planes” or horizontal pushings for- ward of the rocks on the up-throw side. The coast sections of Loch Eriboll show these dislocations clearly. Beginning with gentle foldings they increase until the order of the strata is reversed. In Durness, for example, the overlying schists have been thrust over westwards across all the other rocks for at least ten miles. Some of the overlying bands are Archean gneiss, others Silurian quartzite, and in one case a mass of the Upper s g 390 General Notes. o [Apa Durness limestone can be detected. The crystallization increases, however, so much that it becomes impossible to determine the original character of the rock by examination in the field. From the remarkably constant relation between the dip of the Silurian strata and the inclination of their reversed faults, Professor Geikie concludes that these dislocations took place before the strata had been seriously disturbed. THE THEATER OF THE EARTHQUAKES IN SpAIn—M. Hébert recently presented to the French Academy of Sciences a commu- nication upon the earthquakes in the south of Spain—cataclysms more violent than any which have visited Spain in historic times. If the details furnished by the papers are examined, it will be * evident that the localities recently disturbed by earthquakes are almost all situated on two zones, the one to the south of the Jurassic and Cretaceous mass which bounds the provinces of Malaga and Granada, the other to the north of it. In the south- ern zone the most severely visited localities were Antequera, alaga, Velez, Torros, Alhama, Granada, etc.; while the north- ern zone comprehends Cadiz, Xerez, Seville, Cordova, Linares, etc., and Valencia, all towns where shocks have been felt. The rest of the peninsula does not seem to have suffered much from this instability of the Mediterranean regions, except Albuquerque in the parallel of Lisbon, destroyed Dec. 26th and 27th, and some slight shocks in Galicia. M. Hébert called attention to the Balearic isles, which are situated between the two zones, are ele- vated eighty meters or more above the sea-level, and are com- posed at the: surface of horizontal beds of Quaternary age. These islands have therefore been raised more than a hundred meters since the Quaternary epoch, and this elevation has been limited northward and southward by fractures in the line of prolonga- tion of the defined zones of dislocation above. Thus it is clear _ that the cause of dislocations in these regions is always present and always active. GroLocicaL Notes.—General—A letter from Capt. C. E. Dut- ton upon the basalt fields of New Mexico, has been contributed to Nature. The center of activity is Mount Taylor, otherwise the San Mateo mountains, a volcanic pile 11,380 feet high, carve into numerous spurs by magnificent gorges. It was originally built by outbreaks both from its flanks and summit. From this ft 1885. ] Geology and Paleontology. 391 identified. The “necks” or “chimneys” which are left standing in the valley plains beyond the farthest verge of the lava-capped mesas form one of the most striking features of the country. One is nearly two thousand feet high. In the wide valley-plains between the mesas are newer fields of lava, some so fresh that one might think them scarcely a century old, and it is clear that they were erupted after many a square mile of strata overflowed by the older basalts had been eroded away. No vents are found in connection with these younger eruptions, nor have any scoriz been discovered. Some of them seem to have flowed from small depressed cones at their upper ends. One stream is sixty miles long. The ejecta found in connection with the older basalts are in relatively small quantity. Cliffs, mesas, terraces, carved buttes and gorgeous colors are as characteristic of the New Mexico plateau region as of that of Utah, and the Cretaceous system is better preserved. The younger basalt is much like the rougher lava of Mauna Loa. As a conclusion of his studies upon the origin of phosphates of lime in sedimentary formations M. Dieu- lafait announces that the waters which have excavated the calca- reous rocks of the north-west of France, and formed the phos- phorites, are exterior waters circulating from above downwards, It thus follows that, contrary to current ideas, deposits similar to those of which the phosphorites form part, wherever found, and whatever their importance, do not owe their origin to internal but to external causes. animals Paleophones nuncius. The four pairs of thoracic feet in this scorpion are like those of the embryos of many other Tra- cheata and resemble those of Campodea, The same appendages in the Carboniferous scorpions are like those of existing species. Cenomanian—The Elobi islands, upon the west coast of Africa and in the first degree of north latitude, are formed of horizontal beds of sandstone, poor in fossils. One of the species met with, Schléinbachia inflata, characterizes the Lower Cenomanian of Eu- rope, and is particularly abundant in the French departments of Yonne and Aube. These beds, according to M. Ladislos Szaj- nocka, are continued along the Gaboon coast to the islands of Muni and Mounda, and appear also to stretch along the west coast of Africa along the Sierra da Crista and the Sierra Camp- lida to Mossamedes and Benguela. 392 General Notes. [ April, MINERALOGY AND PETROGRAPHY.! RECENT TEXT-BOOKS OF MINERALOGY AND PETROGRAPHY.—The appearance of the second edition of Professor E. S. Dana’s well known Text-book of Mineralogy,’ containing over fifty pages of new matter in the form of supplementary chapters, brings this admirable introduction to the science fully up to date, as well in respect to its treatment of the newest methods and apparatus for mineralogical investigation as in the completeness of the list of species mentioned. Professor Gustav Tschermak’s excellent Lehrbueh der Mineral- ogie, completed only near the end of 1883, fills the same place ni the German language that Dana’s text-book does in English, and fills it so well that a second revised edition has already appeared,’ having the imprint 1885. This work is especially strong in its treatment of the physical, particularly the optical, properties of min- erals, as well as their modes of origin and occurrence. Consider- able space is also devoted to their chemical relations, and an at- tempt made to classify them according to a scheme based some- what on the periodic arrangement of the elements. The descrip- tion of the species is, however, often too meager even for a text- book, many important, minerals being mentioned only by name. Professor A. de Lapparent, of Paris, author of the recent Traité de Géologie, has also just issued a mineralogical manual entitled Cours de Minéralogie* A large proportion of this work is de- voted to the treatment of crystallography, in which the cumber- some system of notation suggested by Haiiy and developed by évy and Des Cloizeaux, is retained, as indeed it is in nearly all French works on mineralogy. The arrangement of the species is merely in accordance with the frequency of their occurrence. In other words the classification is purely geological, and it is among geologists that the work will probably prove to be of the greatest use. The second volume of Hilary Bauerman’s Mineralogy, de- voted to the description of species, is very unsatisfactory. Mu that is very important, especially many results of the best recent mineralogical work, has been altogether disregarded, and the author conveys the impression of being by no means thoroughly acquainted with the newest methods or the latest discoveries in the science of which he treats, _ Dr. Heinrich Baumhauer, well known for his researches on the figures artificially etched on crystal planes by chemical reagents oo by Dr. Geo, H.

Dr. Aristides Brezina, of the University of Vienna, has pub- lished the first part of an elaborate and exhaustive series of crys- tallographic researches, undertaken in competition for a prize offered by the Royal Academy of Science? The first part, although covering over 350 octavo pages, deals only with meth- ods of investigation, and constitutes a most valuable addition to the works on mathematical crystallography. Fr. Ulrich, of Hanover, is the author of a quarto pamphlet, containing sixteen pages, covered with figures to illustrate the relations of the crystalline forms of the different systems, the de- velopment of hemihedral forms and some characteristic combina- tions of common minerals3 Many of the figures are colored. and, while roughly executed, they are useful in making plain to beginners some of the more elementary principles of crystallog- raphy.. No printed explanations are appended. : A much-needed elementary text-book of microscopical miner- alogy has very recently appeared, by Dr. Eugen Hussak, o Gratz.‘ Only such species are treated as enter into the composi- tion of rocks, and these almost exclusively in reference to their appearance and the methods of their identification in thin sections under the microscope. The first part of the book deals with the methads of microscopical petrography—the construction of the microscope and the manner in which the optical properties of minerals are used for their identification ; the method of sepa- rating rock constituents by means of a heavy solution, micro- chemical analysis and some of the most peculiar characteristics common to all minerals when examined in thin sections. The second part contains the distinguishing microscopic peculiarities of each rock-forming species arranged in tables, as is the case in Professor Brush’s manual of Determinative Mineralogy. These are sometimes too concise to be satisfactory, but they nevertheless contain a great amount of information in a very small space. The means of distinguishing similar minerals are especially empha- sized. A valuable list of references to the more important micro- scopic studies of different rock-forming minerals, arranged alpha- betically, is annexed to these tables. The book is not a text-book of petrography, since.rocks themselves are not described, but 1 Kurzes Lehrbuch der Mineralogie einschliesslich der Petrographie. Von H. Baumhauer. 8vo, pp. 190.

Although quite elementary, it will prove very valuable to those commencing work in microscopical mineralogy, to whom the vast amount of material contained in the larger manuals is often discouraging. CROCIDOLITE FROM THE CAPE oF Goop Hopr.—Considerable which jewelers generally designate as crocidolite. In its struc- ture it much resembles the well-known “catseye,” and when properly cut it can scarcely be distinguished from this except by its color, a fact which frequently causes it to be called “tiger’s .” The true crocidolite is an asbestiform hornblende, possess- ing a blue color, like its more compact equivalent glaucophane. Among other localities it occurs abundantly near the Orange river in South Africa, from which place specimens were analyzed by Klaproth? as early as 1815, and again by Hausmann and Stro- meyer’ in 1831. The latter authors gave it the name crocidolite in allusion to its fibrous structure («poxés, a woof). The occur- rence of this mineral in Africa has been described by Cohen? and Stow." The former says that a range of mountains extends in N. N. E. direction from the Orange river through the province of West Griqualand, the central part of which is known as the Asbestos mountains. Here the crocidolite occurs in veins from one to six inches in width, together with vast quantities of jasper and other forms of silica. Sometimes the crocidolite is pure and is then blue in color, soft, and easily separable into the finest fibers; more often, however, it is more or less decomposed and toa greater or less extent replaced by quartz. It is upon this alteration and replacement that the commercial value of the min- eral depends. The yellowest specimens are most changed and owe their color to the almost complete oxydation of the iron. WibeP’ studied the mineral in 1873 and concluded that it was a complete pseudomorph of quartz after crocidolite, only the iron of the original mineral being left in the form of gothite. Renard and Klement® have recently contributed an exhaustive paper on the subject.’ Analysis of the yellowest variety gave: PROG Mee 6 Rta ole Oo oO 85.05 4.94 - 0.66 0.44 8.26 0.76 Total 100.11 i Spn Abhandlungen gemischten Inhalts, 1815, pp. 233-242.

Scharizer, of Vienna, has studied the hornblende from Jan Mayen, and appends some interesting remarks regarding the general chemical constitution of the aluminous hornblendes.? He regards them as isomorphous mixtures of typical actinolite (Mg Fe), Ca Si Si, Op and a molecule R, R, Si; O,., to which he applies Breithaupt’s old name, syntagmatite. Merian contrib- utes an interesting attempt to trace the relation between the com- position of an eruptive rock and that of the pyroxene mineral which it contains. J. Eliot Wolff gives a short note on the occurrence of nephelinite and nepheline-tephrite, both rich in a mineral of the sodalite group and often containing olivine, in the razy mountains, an isolated range north of the Yellowstone river, in Montana. These rocks have never before been observed within the limits of the U. S. ery, by J. S. Diller, of a new type of volcanic rock—a_ hyper- sthene basalt—on Mt. Thielson, Oregon’ on the surface of which fulgurites were found to be largely developed. This rock is new, but exactly fills a vacancy in the accepted rock classification —— € same writer mentions peridotites which break through the Carboniferous strata of Kentucky in the form of dykes, enclosing fragments of the adjacent rock. He also finds, upon microscopic given an elaborate microscopic study of the volcanic and cosmic dust that forms so large a portion of the deepest ocean deposits. —Holst and Ejichstadt® have described from _Slattmossa, in Sweden, an amphibole granite having a beautiful spherulitic Structure not inferior to that of the well known “ napoleonite or “ corsite,” a nodular diorite from Corsica, described by Vogel- 'Tschermak Min.

BOTANY. ° HYBRIDIZATION oF Porators.—During the past year some ex- periments were made at Reading, England, upon the grounds of Messrs. Sutton & Sons, the eminent potato growers. Un- der the advice of Mr. J. G. Baker the attempt was made to secure a hybrid between the common potato and the Darwin potato (Solanum maglia) from the southern part of South Amer- ica. The experiment is reported as having been successful, and we may look ere long for the tubers of this new form. “ Every gardener and farmer may now welcome the birth, so to speak, of a hybrid which we may hope will enable the potato plant to resist the attack of parasites, and especially of those of the devastating fungus, Peronospora infestans.” HETEROECISM OF CEDAR APPLES.—Dr. Farlow has been study- — í: 1.

The causes which have produced the dissimilar composition of these two forests must be sought in the climatic conditions of a geological era earlier than our own and in the actual topographi- cal formation of the continent. The forests of the Atlantic and the Pacific regions, dissimilar in composition in the central part of the continent, are united at the north by a broad belt-of sub-arctic forests, extending across the continent north of the fiftieth degree of latitude. One half of the species of which this northern portion is composed, ex- tends from the Atlantic to the Pacific; and its general features, although differing east and west of the continental divide, in con- formity with the climatic conditions peculiar to the Atlantic and the Pacific sides of the continent, still possess considerable uni- formity. The forests of the Atlantic and the Pacific regions are also united at the south by a narrow strip of the flora peculiar to the plateau of Northern Mexico, here extending northward into the United States. Certain characteristic species of this flora extend from the Gulf of Mexico to the shores of the Pacific, and the outposts between the Atlantic and the Pacific regions.—Fro- fessor Sargent in Vol. ix of the roth Census of the United States. FERTILIZATION OF THE LEATHER-FLOWER (CLEMATIS THE VIORNA).—The leather-flower is a rather™curious plant, climbing by means of its leaf-stalks among the low underbrush. The -flower (Fig. 1) it bears is bell-shaped and hangs pendent from a somewhat long peduncle, which extends in a horizontal direction. ` It has no petals ; four sepals taking their place. These are very thick and leathery, and are colored purplish without. The edges and inner part of the sepals are white. The tips are recurved, and these, together with the white edges of the sepals, perhaps serve as guide marks, directing the insect to the entrance below as a means of obtaining the honey. The bee, which I find to be the fertilizing agent, holds to the recurved tips of the sepals while effecting its honey-gathering, and this is the more obvious purpose of these tips. The outer stamens begin to open then those next within, being in advance of the pistils. But before the inner stamens are ready to shed their pollen, the stigmas are also ready, so that were it not for a very ingenious 398 : General Notes. [April, arrangement, pollination would easily take place. The back of the anthers and the entire surface of the little tips extending above them are hairy. So are likewise the styles (Fig. 3). The calyx is closely contracted at its opening, pressing together the numerous stamens and pistils into a compact mass. Owing to the greater size of the pistils, the stigmas extend beyond the an- thers (Fig. 4), and since the close packing brings the hairs on the Fig. I. Fig. 2.

But at a later period the pressure of the sepals relaxes, the stamens are looser, and self-fertilization is not absolutely impossible, but certainly un- necessary, judging by the frequent visits of bees. The insertion of the bee’s proboscis releases the pollen, which falls upon the abdomen and thorax, to be left upon the more prominent stig- mas of the next blossom. The nectary is at the base of the fila- ment.—Aug. F. Foerste, Granville, Ohio. Prant Micrations.—Fifteen years ago there were no dande- lions in the Ames flora (in. Central Iowa), now they are very abundant, and have been for half a dozen. years. Then. there were no mulleins (Verbascum thapsus), now there are a few. Then the low and evil-smelling Dysodia chrysanthemoides grew by the roadside in great abundance, now it is scarcely to be found, and is replaced by the introduced “ dog-fennel” (Arthemis cotula). Then the small fleabane (Erigeron divaricatum) abounded on dry soils, now it is rapidly disappearing. Then no squirrel-tail grass (Hordeum jubatum) grew in the flora, now it is very abundant, and has been for ten years. Then there was no bur-grass in the flora, now it is frequently found, and appears to be rapidly increas- ing. Both of these grasses have apparently come in from the west and north-west. Fifteen years ago the low amaranth (Ama- vantus bvitoides) was rather rarely found; now it is abundant and - _ has migrated fully 150 miles north-eastward. This plant has cer- =~ tainly come into the Ames flora from the south-west within the last twenty years. In Nebraska, I am informed by the old settlers, that there have been notable migrations of plants within the past twenty or thirty =~~ years.

The blue- stems now grow in great luxuriance all over great tracts of the plains of Eastern Nebraska, where twenty years ago the ground was practically bare, being but thinly covered by buffalo grasses, In Dakota it is the same, the blue-stems are marching across the plains, and turning what were once but little better than deserts into grassy prairies.— Charles E.

There is a great deal of exceedingly valuable information given upon the geographical range of species, and also much in the way of notes upon habitats. Dr. Gray’s memorial of George Bentham in the American Fournal of Science for February, contains one of the fullest accounts of the very full life of the venerable botanist, whose death the world still mourns. “ His life was a perfect and precious example, much needed in this age, of persevering and thorough devotion to science while unconstrained as well as un- trammeled by professional duty or necessity. For those endowed with leisure, to ‘ live laborious days’ in her service, is not a com- mon achievement.”——Nos. 1 and 2 of the Yournal of Mycology have been received, and we can only say at this time that the matter is, in the main, good, but that the editor has not yet suc- ceeded in getting from his printers as good work as is desirable. This, however, will doubtless be improved in the future. ENTOMOLOGY. Generic Position oF POLYDESMUS OCELLATUS.—In a letter to Professor Packard the undersigned writes as follows : In the American NATURALIST, April, 1883, you have published per on “a new species of Polydesmus with eyes,” which you have called Polydesmus ocellatus. As can be seen from your description given there, the new myriopod must be a species of the genus Craspedosoma Leach (Transac. Linn. Society, Vol. X1, p. 380, printed 1815), and not of the genus Polydesmus Latr. ; for the latter genus is always characterized by the want of eyes and by the number of segments being twenty, whereas the for- mer genus is characterized by oculi composed by multiseriated ocelli and by the number of segments being thirty or, in younger specimens, less, from twenty-seven to twenty-nine. In consequence of the necessity of ranging your species in another genus, all the members of which are provided with eyes, the specific name ocellatus should be removed and another intro- duced instead of it. I propose the name Craspedosoma pack- _ As I have reason to suppose, you are probably not in posses- sion of Dr. Fr.

[ April, tinguished by a black oval dot; just as in other larve with tracheal gills, as described by Palmén, the stigmatic branches are completely closed. The larvæ are ordinarily found attached to stones, and are rather more frequent in stagnant than in running water. They form for themselves a chamber with delicate but closely spun walls, and they do not leave this, as a rule, until they attain to the imaginal state. The spaces at the edge of the co- coon only serve asa means of exit for the fæces ; they live on the diatoms and other cellular Algæ which grow on the stones to which they attach themselves. They almost always fix themselves by their backs to the stones, and in correlation with this we ob- serve that they present the remarkable condition of having their dorsal surface pale, and their ventral dark. This is not however, to be regarded as a protective adaptation, but as the result of an earlier condition in which the whole of the larva was darkly pig- mented; the paleness of the back is due to the want of light. After an account of the pupa and of the homes in which it dwells, the author passes to some other species of the same genus, all of which are Brazilian. These are much less common, an their specific characters are not yet fully worked out, but there are probably five species. The gills, which are always unbranched, never attain to the relative length seen in C. pyropalis, but they are always more numerous. The covering of the pupa contains air- spaces in its outer division, which are connected with that of the inner, but as the stones or alge forbid any exchange of gas with the exterior, this can only be effected by the spaces in which the water is able to pass; this explains how it is that we sometimes find the air-chambers on the side of the house which is attached to the stone. : ORGANS OF HEARING AND SMELL IN SPIDERS.—F. Dahl pro- poses to classify spiders according to the charac ter and disposition of the auditory hairs on the limbs of these animals, as follows : 1, Tibia with two series of auditory hairs, metatarsus with one hair, and tarsus with a rudimentary pit or depression free from hairs, e. g. Epeiridz, Uloboride, Theridiidz, and Pholeide. 2. Tarsus with no rudimentary depression for auditory hairs, usually bearing a number of hairs like the metatarsus and tibia, e. g. Territelariz, Dysderide. The remaining number of this class are further subdivided ac- cording to the presence of one or two series of auditory hairs on the tarsus. A single series is characteristic of Amaurobiide, Agalenidæ, Philodromide, Thomisidz, and Attide. Two series _ occur in Drasside, Anyphoenide and Lycoside. = _ Dahl has satisfied himself that these auditory organs can appre- =~ €late not only sound, but also variations of atmospheric pressure, f ich = An olfactory org is stated to exist on the maxilla.

Rafin described a species of ant which he has observed in the Island of St. Thomas, and which he proposes to call Formica ignivora.

Fourn. Roy. Microscopical Society, éc., 1882, EnTomotoaicaL Nores.—In a paper on the larvz and larval ` cases of some Australian Aphrophoride, F. Ratte describes those of a species probably of Ptyelus, which are true shells, contain- ing at least three-fourths of carbonate of lime, and resembling in shape some fossil and recent serpulz, some being conical, others serpuliform or helicoidal. The conical shells.are fixed on the branches of some species of Eucalyptus, the mouth turned up- wards, the larva being placed in it with the head downwards—— In his notes on the flight of insects, Dr. v. Lendenfeld contests the views of the French physiologists that the position and move- ments of the wings of insects are merely the results of the mechanical influence of the resisting air, and gives instances where muscular contraction had been clearly proved. DE S. W. Williston begins, in the Bulletin of the Brooklyn Entomo- logical Society for February, a series of papers on the classifica- tion of North American Diptera. The first paper is extracted from a monograph of the North American Syrphidæ, now ready for the press, and which gives the results of a careful study of nearly 275 species of this family. The committee on a union of Papilio with the Bulletin haye reported in favor of it, and recommend that a monthly journal be issued under the name of Entomologica Americana, at $2 a year. n entomological society has been established at Newark, N. J. In an examina- tion of over 1500 specimens, Mr. C. H. T. Townsend found 115.3 males to every 100 females (Can. Ent., Dec, 1884). Mr. W. H. Edwards recounts, in the Canadian Entomologist for December, further experiments upon the effects of cold applied to chrysalids of butterflies. Nature for Jan. 29, gives good figures and de- scriptions of the two fossil scorpions from the Silurian of Swe- den and Scotland lately discovered. A writer in the same number claims that the leaf-eating ant has something to do with the barrenness of the pampas of the La Plata, as they defoliate Eucalyptus plantations, cutting off the first leaves. 404 General Notes. [April, ZOOLOGY. Tue ANATOMY OF THE Hirupinea.—Mr. A. G. Bourne (Quart. Journ. Mic. Sci., July, 1884) contributes the results of observa- tions upon ten genera of Hirudinea extending over a period of four years. His conclusions with regard to the vascular system are, that the whole of the vessels and sinuses are in continuity; that the lateral vessels communicate freely with one another with- out the intervention of any capillary system, that they possess branches opening into botryoidal or other capillary networks of the “ cutaneous ” system, and that they form nephridial capillaries and also capillaries upon the intestinal wall. The nephridial capillaries are partly collected again and carried to the capillaries of the cutaneous system, and partly unite to form a vessel which is con- nected with the perinephrostomial sinus. The dorsal sinus. is directly connected with the ventral sinus, and both communicate with: (1) The cutaneous networks; (2) the capillary network upon the walls of the crop; (3) the capillaries upon the intestinal wall and the spiral valve ; (4) the perinephrostomial sinuses. The botryoidal and other cutaneous capillary networks communicate ‘with branches of the lateral vessel, and also with the extensions of the dorsal and ventral sinuses, of which the capillaries on the walls of the crop are developments. The vessels of the walls of the gastro-ileal tube are directly derived from branches of the lateral longitudinal vessels ; the ventral sinus contains the nerve chain, the perinephrostomial sinus contains the nephridial funnel, and the network of capillaries on the testicular wall potentially contains the testis. The lateral vessels and their branches have a definite muscular wall, wanting only on their smaller branches and capillaries, but the dorsal and ventral sinuses, and the exten- The writer leaves unsettled the vexed question of the relation- ship of the leeches to other Vermes, but appears on the whole more saa to approach them to the Piatyelminths than to the ye NEUMAYR’S CLASSIFICATION OF THE LAMELLIBRANCHS.— Neu- mayr (Sitz. k.

For these forms, supposed to have two equal ad ti les an _ aaduc nd an entire mantle-line, the order Palæconchæ _ 1s proposed. From these are supposed to diverge the Desmo- donta, without hinge-teeth or with irregular hinge-teeth, with i 1885.] Zovlogy. 405 two equal adductor muscles and with a pallial sinus; and the Taxodontæ, with numerous undifferentiated teeth and two equal muscles. To the first of these groups belong the Pho- ladomyidæ, Corbulidæ, Myidæ, Anatinidæ, Mactridæ, Paphi- æ, Glycimceride and Solenidæ?, and to the second the Desmodonta. From the Taxodonta branch off in one direction the Heterodonta, with distinct cardinal and lateral teeth fitting into each other and two muscle-impressions (Najadæ, Cardinidæ, Astartidæ, Crassatellidæ, Megalodontidæ, Chamidæ (Rudistes) (Tridacnidæ), Erycinidæ, Lucinidæ, Cardiidæ, Cyrenide, Cyprin- idæ, Veneridæ, Gnathodontidæ, Tellinidæ, Donacidæ), and in another, the Anisomyaria, with irregular or no hinge-teeth, two -unequal muscles or one only, and no pallial sinus. These form two suborders, Heteromyaria (Aviculidæ, Mytilidæ, Prasinidæ, Pinnidæ) and Monomyaria (Pectinidæ, Mytilidæ, Spondylidæ, Anomidæ, Ostreidæ). The Trigonidæ are considered a suborder of Heterodonta. ANTENNARY GLAND OF CyrHERIDÆ.—W. Müller-Blumenau has discovered that Æ/pidium brossliarum is able to secrete a sticky material while in water; the observations made in connection with this discovery led him to the belief that the animal was able to spin, and that the spinning organ was placed in the second pair of antennz. The organ so well known to be present at the base of this pair of appendages has been supposed to be poisonous in function, but no direct observations have ever been made in sup- port of this view, and it is opposed by the delicate nature of its flagellum, which could never be supposed to be capable of inflict- ing a wound. When the animal is found hanging to glass its an- terior end is always nearest to the glass, and the creature takes an oblique position. The author points out the difficulties pre- sented by the habits of the animal in determining the question which he has investigated, but it would seem to be certain that the antennary gland is possessed of the power of secreting an at- taching thread —¥ourn.

The author referred to hibernation as being in some 406 General Notes. [April, cases a voluntary act. Some of the observations on animals con- fined in our laboratory for the purpose of study, may throw more light on this subject. These animals are all well known species, and our aim is usually to keep them in surroundings as nearly like their natural habitations as possible. The temperature can- not, in the single room at present devoted to this use, be kept at a degree which will suit the habits of all of them, but the effects of its change on each is noted. A number of frogs (Rana halecina) were placed in a closed glass case, with growing plants to study the balancing effect of their respiration. Plants and frogs seemed to thrive excellently, and during the four months trial, the temperature being kept at . about 70° F., the latter showed no evident signs of hibernation, though the case stood in front of a window against which the snow was often falling. To observe the effect of a lower tempera- ture, the case was moved to a cooler place (40°), and immediately the frogs, using their front legs like dogs, dug under the moss and stones, and remained out of sight until the former temperature was renewed. Similar experiments tried with salamanders, snakes, toads, houseflies and hornets, revealed at once a desire to hide during the lower temperature, but a complete absence of any such tendency when the normal degree of heat was preserved. In every one of these cases and a number of others, hibernation seemed to be forced. If the temperature was lowered, and they were at the same time prevented from burying themselves, they gradually became stiff and lifeless, but could in every case tried, except the last two mentioned above, be resuscitated upon the application of heat. uring this last fall a scorpion, shipped from the South in a _bunch of bananas, was subjected to like treatment with the same results. When cold it was so helpless that it could be handled with impunity; but when its box was placed near the fire, it id dart about with elevated tail in the manner peculiar to itself. With some of our animals experiments have given different re- sults. A wood-tortoise, though given a warm corner near the fire, could not be persuaded to pass the winter above ground. It e exhibited very evident signs of uneasiness as the snow came, and, ~as soon as material was furnished, burrowed out of sight. The d inaction. Their den was placed by a window on the de of the building. Their food has remained untouched 1885,] Zoblogy. ` 407 window they are found to be curled up together in their straw nest. It may be that in this case “ possuming” is only another word for hibernating. All of our experiments lost a ‘part of their value because the animals are in confinement; but, with the two exceptions given above, where habit controlled, all seemed to prove that hiberna- tion is not an inherited and peculiar trait, but one that may be adopted when the conditions demand it. The NATURALIST shall hear of our further work in this direction —W. W. Thoburn (Lab- oratory of Tilinois Wesleyan University).

A Crow Crackinc Crams.—My son-in-law assures me that years ago it was not so rare to see, at Port Monmouth, the com- mon crow (Cervus americanus) take a quahog (Venus mercenaria) up high in the air and drop it on a certain fence with a flat top- rail, thus cracking it.

A Beaver Dam BUILT witHour Woop.—The idea that the beaver must have wood with which to build his dam is so univer- sal that an exception to the rule seems worthy of record. __ In September of 1883, near the headwaters of Beaver river, 408 » General Notes, [April, Dakota, the writer discovered a dam freshly built of mud, and coarse, marshy plants. No trees or bushes could be seen any- where in the vicinity. It was about twenty-five feet in length, thrown across a sluggish stream about half that width. Its level top was about four feet higher than the bottom of the channel. The dam was not more than half-filled with water.— F. E. Todd. TuE WILpD Horse or THIBET.—The celebrated traveler, Prze- valsky, on his return from his third great journey in Central Asia, brought to St. Petersburg an example of a new species of Equus. This was described in 1881 by Mr. J. S. Poliatow as Æ. przeval- sky. It has warts on its hind-legs as well as on its fore-legs, and has broad hoofs. These characters ally it to the true horse, but the long hairs of the tail do not commence until about tHe middle of that appendage. It is thus intermediate between the horse and the asses, to which category the other known wild species of Equus belong. Its mane is short and erect, there is no forelock, and no trace of a dorsal stripe. The stature is small, the-legs very thick and strong, the head large and heavy, and the ears smaller than in the asses. In color, it is whitish gray, paler and whiter beneath and reddish on the head, and on the upper part of the legs, which are blackish from the knee downward. Przevalsky’s wild horse inhabits the great Dsungarian desert between the Altai and Tianschan mountains. The Tartars call it “ Kertag,” and the Mongols “ Statur.” It goes in troops of from five to fifteen, led by an old stallion. It is lively, very shy, with sight, smell, and hearing well-developed, so that it is exceedingly diffi- cult of approach. It seems to prefer the saline districts, and to be able to do without water for long periods. Thus it can only be hunted in the winter, when melted snow can be obtained. Przevalsky only met with two herds during his whole stay in the desert. The only specimen brought to Europe is in the museum of the St. Petersburg Academy of Sciences. ZOOLOGICAL Notes.—Sponges—Professor W. S. Sollas has recently studied the development of Halisarca lobularis from specimens obtained at Roscoff. Schulze, whose specimens were taken in the Mediterranean, found that the development of the young within the parent sponge did not proceed further than the formation of the blastula, or at most of an incipient gastrula ; whereas in those observed by Sollas the embryo became -muc developed within the parent, and the blastula stage was slurred over, apparently to economize space. No segmentation cavity was observed, but directly a cavity was necessary, the loosely aggregated cells of the morula packed themselves closely to- gether to form the wall of the unfinished blastula, leaving their = overplus in the interior in irregular heaps which subsequently ~ arranged themselves into a unicellular layer along the line of the ~ infolding wall of the gastrula. Professor Sollas attributes the 1885.) Zoölogy, 409 difference in development between the Mediterranean and Ros- coff specimens to the difference of conditions, the former sea be- ing without heavy tides and powerful currents, so that the larve can safely issue into the water at an early stage. Dr. Senden- feld claims, in Zool, Anzeiger, Jan. 26, to have discovered a scat- tered system of mesodermal nerve-cells in’ several kinds of sponges. Mollusks—After a study of the morphology of Rhabdopleura from specimens obtained at Lervik, near Bergen, Norway, Pro- fessor E. R. Lankester does not decide whether the form is poly- zoan or molluscan, but inclines to the view that both it and Cephalodiscus are degraded lamellibranchs. The colony consists of branching tubes, built of a series of rings, each of which is separately secreted and added to its predecessors by the so-called buccal shield or pre-oral lobe of the polypide. A completed branch ends in an upstanding polyp-tube, while in a growing branch the axis runs beyond the last erect polyp-tube. The axial tube is divided by septa into segments, one corresponding to each polyp. When a bud reaches a certain stage of development it breaks through the wall of its chamber and grows outwards at a sharp angle. . Occasionally it atrophies, leaving a sterile cham- ber. The buccal shield or disk is locomotive as well as secretive, and is covered with fine cilia, which occur also on the lophopho- ral filaments of the arms right and left of it. In the center of the ringed caulotheca or tube is the axial stalk which connects and bears the polyps. This is soft in the polypides, hard on the stem, but every hard portion is formed by the shrinkage of the soft stalk and the development of a cuticle. An internal skele- ton exists in the lophophore and in the axis. The embryology of this curious form is as yet unknown, nor is it known whether the sexes are distinct or the colony persistent from year to year. More Pleurotomide. Mr. E. A. Smith describes (Aun. and Mag. Nat. Hist, Nov., 1884) thirty additional species of this group.——In the same magazine (Oct.) Dr. R. Bergh has a paper upon the affinities of Onchidia. After an examination of the structure of various organs, the writer arrives at the conclusion that “the Onchidia agree with the Pulmonata in the structure of the nervous system, in the existence of a lung and of a parenchy- matous kidney, in the presence of a peculiar pedal gland, and in various peculiarities of the generative system. They branch off from the Pulmonata; they are Pulmonata which have adapted themselves to an amphibiotic or marine mode of life. Crustaceans—Among new forms of Crustacea dredged by the Albatross in 1883, are an ally of Ethusa, taken in 1496 to 1735 fathoms, a species of Galacantha M. Edwds., in 1479 fathoms, two forms of Pentacheles, between 843 and 1917 fathoms, Notostomus, a Palemonid, six inches long and of an intense dark crimson, in 410 General Notes. | April, 1342 fathoms; three species of a new genus allied to Pasiphe and also to Hymenodora ; a Penæid of the genus Aristzas, a foot in length, and a large Sergestes, three inches long. The size of these new shrimps is remarkable, but is greatly exceeded by that of some of the deep-sea crabs. Thus the great spiny Lithodes agassizii has a carapace seven inches in lengthand six in width, and measures above three feet over the outstretched legs. Arachnidans—The development of Chelifer differs from that of other arachnids in the existence of a larval state as yet little known, and the structure of which has been found by M. J. Bar- rois to be more complicated than was stated by Metschnikoff. The number of pairs of feet is five. The nutritive vitellus is sur- rounded by a layer of exodermal cells preceded by an ample organ of suction opening on the ventral aspect between the two large claws (second pair). The whole forms a digestive apparatus destined to pass nutritive material into the interior of the larva. The larva is fixed upon the ventral face of its mother, and sub- sists parasitically upon her. The sucking apparatus is destined to fall, and its mode of elimination is singular. In the earlier Stage the ventral nervous band consists of two parts, one in front of, the other behind the sucking organ. Afterwards, when the two bands are united into a continuous cord, the sucking organ is thrust outwards, becomes attached only by a thin cord below the definitive mouth, and falls at the same time with the larval envelope. Fishes——Karl Mobries, in a letter to Nature, maintains that flying fish are incapable of flight “ for the simple reason that the _ muscles of their pectoral fins are not large enough to bear the weight of their body aloft in the air.” The pectoral muscles of birds weigh on an average } of the total weight of the body, those of bats 75, those of the flying fish only +. The impulse is given while still in the water by the powerful masses of muscle along the sides of the body, masses which are larger than in any other fishes of similar size. The flickering motion which has been noticed is only a vibration of the elastic membrane of the pectorals, which occurs whenever the fins are in a horizontal position parallel to the wind. the natives. The last moa hunt of which memory is preserved, according to Mr. White, took place near Whalatone, in the Bay of Plenty. The feathers of birds killed there were until recently _ inthe hands of a chief named Appanui. _ 1885.] Embryology. 411 EMBRYOLOGY.! ON THE POSITION OF THE YOLK-BLASTOPORE AS DETERMINED BY THE SIZE OF THE VITELLUS.—This principle, which I have to some extent elaborated elsewhere (Cont. Embryog. Oss. Fishes, p. 114), in so far as it applies to the ova of bony fishes of different species, differing greatly in the dimensions of the vitellus, may be expanded so as to throw some additional light upon the growth and closure of the blastoderm of other groups of Vertebrata. In the paper cited I have shown that the position of the point of closure of the blastoderm in relation to the original position of the germinal disk in Teleostei is to a large extent determined by the size of the vitellus, and consequently also stands in an inti- mate relation to the variation of the area of the vitelline surface over which the blastodermic membrane must grow, that is to say, with the increase of the superficial area of the vitelline globe upon which the germinal disk is superimposed, and over which it spreads as the blastoderm, the position of the yolk blastopore must vary. A yolk blastopore is met with only in such forms of ova in which there is a distinct, unsegmented or partially segmented vitellus developed. As a rule, it does not coincide with the posi- tion of either mouth or anus, but when such a coincidence does occur the yolk blastopore answers nearly or quite to the perma- nent anus of the Vertebrate embryo. In the Vertebrates the yolk blastopore is apt in most cases to close behind the position of the permanent anus; in large-yolked cephalopod ova it closes at the anterior or perhaps more properly on the ventral face of the yolk- sack, and seems to have no relation to either mouth or anus. l Edited by JoHN A. RYDER, Smithsonian Institution, Washington, D. C. 412 General Notes, [April, the blastoderm opposite the embryo must grow in width more rapidly than, the embryonic half in which the embryonic shield is formed. These different modes of the growth in length of the bodies of embryos of different species of osseous fishes may easily be veri- fied by the observation of the progressive growth of the blasto- derm of the living ova, and go far towards reconciling the differ- ences of opinion which have been expressed by different observers as to the growth of the blastoderm over the yolk. It is at any rate evident that the manner in which this is accomplished in one form does not necessarily hold true of another. It is very significant that two large-yolked types, viz.: the Sau- ropsida and Elasmobranchii should both have the embryo dis- placed in position in reference to the margin of the blastoderm. In the latter, the first traces of the embryo have the normal mar- ginal position at the periphery of the blastoderm, but it is soon folded off, and before the yolk blastopore has closed, the latter finally closing a little way behind the stalk connecting the em- bryo and yolk sack. In the Sauropsida as held by Balfour, the primitive streak apparently represents the linear thickening be- tween the lower vitelline stalk and the point where the blasto- derm finally closed in the Elasmobranchii. ___ It is thus made evident that, whereas the embryonic axis in Teleostei, Chondrostei, Ganoidei, Petromyzon and Amphibia ex- tends back to the point where the yolk blastopore closes, in Sau- ropsida and Elasmobranchii, the embryo is, partially folded off, and the tail begins to bud out before the vitellus is included by the blastoderm, and while the end of the axis of the embryo is still remote from the opening of the yolk blastopore. This con- trast between the two types, as will be evident to the thoughtful person, must be due to the great difference between the bulk of the yolks in the two cases. In the large-yolked forms if the em- bryonic axis were to continue to grow in length and extend quite to the point where the yolk blastopore closes, the body of the embryo would necessarily develop more somites than are present in the adult, so that growth in length of the embryonic axis ceases in the large-yolked forms far short of the point of closure of the blastoderm, covering perhaps only 30° of arc or less of the entire circumference of the vitelline globe. Such a small segment of the circumference of the vitelline sphere when contrasted with g0°-125°, and on up to 180° to 230°, embraced by the primary embryonic axis in Anamniate forms, seems inconsiderable, but is really relatively as extensive as in the latter. € germinal disk of Sauropsida is relatively much larger than that of Teleostei, so that proportionally it probably does not spread over a much larger vitelline surface in the first case than _ In the last in order to include the vitellus, but as the blastoderm _ _ Spreads-in either case, it must be obvious to any one conversant 1885. | Embryology. 413 with the mode in which the embryonic axis is formed during vertebrate development, that in the former growth in length of the axis would necessarily be completed before the blastoderm could spread over and include the yolk. Those forms of vertebrate embryos in which either the true or the yolk blastopore marks the end of the embryonic axis before the appearance of the tail bud might be called ze/eporous, while those in which there is no such coincidence, the yolk blastopore closing some distance behind or remotely away from the end of the embryonic axis, might be called, ateleporous. The first would include Amphibia, Petromyzon, Ganoidei, Chondrostei and Teleostei, the last, Elasmobranchs and Sauropsida. The ova of the two extremes of the vertebrate series Branchiostoma and Mammalia are yolkless, except those o Monotremata, which are probably ateleporous, simulating the Sauropsida in the general features of the development of the blastoderm and early phases of the embryo. The band of tissue from the vitelline end of the umbilical stalk to the edge of the blastodermic rim in Elasmobranchii, and the primitive streak in Sauropsida and Mammalia are probably homol- Ogous structures. In the first instance it is formed by the con- crescence of the margin of the blastoderm as it advances over the surface of the vitellus. In the Teleostei, Ganoidei' and Chon- drostei it would seem that the whole of the margin of the blasto- derm was used up by a process of concrescence to form the em- bryonic axis, whereas in the Elasmobranchii and Sauropsida there is a portion of the rim of the blastoderm remaining behind the development of the Sauropsida in the way in which it occurs in Ichthyopsida, it is known that the primitive streak is related pos- teriorly on either side to the rand-wuilst or ‘marginal thickening of the chick's blastoderm, a structure obviously homologous with the lower layer of the thickened margin of the blastoderm of the a relation to the b: y and int fishes and totally unlike that noticed in zonts, h be seen, differs but slightly from that of bony also supported by the way in which the y relation to the body of the embryo. 414 General Notes. [ April, fish embryo. It is therefore interesting to note that an actual con- crescence from behind forward of this rand-wulst or lower layer or a proliferation of cells from behind forwards would not be im- possible. The zxner mass of cells of the Mammalian ovum while in the vesicular or blastodermic stage is evidently in part homol- ogous with some part of the thickened rim of the blastoderm of lower forms. It is also a matter of great interest in this connection to observe that in the Sauropsida the rand-wulst or germinal wall is not carried along with the extreme edge of the epiblastic stratum quite to the border of the blastoderm all round as in Ichthyop- sida. The epiblastic layer of the blastoderm in the Sauropsida rapidly extends beyond the lower layer or germinal wall, leaving it more or less remote from the outer margin of the germinal area. This peculiarity of development alone would be sufficient to cause the embryo to be formed away from the margin of the blastoderm in the Sauropsida, but even this I venture to Suggest is to be explained by the increase in the size of the yolk of the ova of Sauropsida, the connecting link between the latter, and the teleporous Teleostean ovum being supplied by that of the Elasmobranchs, which probably represents at least one of the steps by which the evolution of the blastoderm of Sauropsida and Mammalia was attained, although it would obviously be incor- rect to assume that these stages of blastodermic evolution were indicative of a serial or successional affiliation through descent. It would probably be much more rational to regard the develop- ment of these differences as being in the main due to an increase in the volume of the yolk as urged by Balfour, and that the causes of variations in its development were therefore to some ex- not the true blastopore, and if it can be regarded as representing the yolk blastopore, which seems very probable, the zzner mass of cells finally involuted on its closure or covered over by the epi- bolic growth of the epiblast, and from which mass the mesoblast and hypoblast are derived, that mass becomes homologous with the marginal lower layer or rand-wulst of such a type as the _ Teleostean ovum. 3 ‘The degeneracy of the vitellus of the ovum of Mammalia may _ Possibly be due to the development of the so-called uterine milk from the uterine glands by which the egg is nourished from with- _ out during a very early stage and before the development of the area vasculosa or the vessels of the allantois is accomplished. 1885. ] Embryology. 415 Intracellular digestion and growth is probably accomplished by some of the cells of the epiblast of the blastodermic vesicle, which send out pseudopodal processes between the cells of the uterine epithelium, as described by Caldwell in the case of the blastoderm constituting the yolk bag of the embryos of certain Marsupialia. Viviparity has not affected the development of the vitellus in the Teleosts, Gambusia, Zoarces and Embiotocide, where foetal development is either intrafollicular or intraovarian. n albuminoid secretion is said by Blake to be found in the temporarily closed gravid ovaries of Embiotocoid fishes ( Journ. Anat. and Physiol., 11, 280), and in this family as well as in some of the viviparous Elasmobranchs, it seems certain that the young developing viviparously are larger than can be accounted for by the size of the vitellus of the recently fertilized egg of the same species. It therefore seems conceivable that the Mammalian vitellus, like the ambulatory, prehensile and other organs of parasitic organisms, may have been atrophied in consequence of the per- fectly parasitic ‘connection subsisting temporarily between the maternal organism and the embryo, as was supposed by Balfour. —John A. Ryder. DEVELOPMENT OF THE SPINES OF THE ANTERIOR DORSAL OF GAS- TEROSTEUS AND Lopnius.—The important memoir of A. Agassiz before cited, shows that the spines of the anterior dorsal of the angler and stickle-back develop in distinct diverticula of the epi- blast, a diverticulum being formed for each spine into which skeletogenous mesoblast is proliferated from its lower or proxi- mal open end. These diverticula soon become free from the an- ' terior end of the median dorsal fin-fold, the latter, in fact, seems to degenerate or be replaced by these diverticula, the first epi- blastic diverticula to be developed are more or less translocated forwards from their original positions, so that in this way these dorsal spines are finally brought to rest on the roof of the skull of the adult, considerably in advance of the point where their de- velopment began on the nape of the embryo. The formation of the singular dorsal appendage of the larva of Fierasfer according to Emery’ is developed in a similar way as a dorsal epiblastic diverticulum, arising from the anterior end of- the median dorsal fin-fold. The singular foliar appendages along its sides grow out secondarily. This transitory organ in Fieras- fer is, however, much more precociously and rapidly developed than the bony, anterior dorsal spines of Lophius and Gasteros- teus; its supporting axis is evidently mesoblastic in origin as in the latter, but degenerates just about the time of the final — morphosis of the animal into the adult condition —/ohn A.

[April, PHYSIOLOGY! _ Function oF THE Tuyrorp Bopy.—The experiments of Zesas (which appear in Arch. f. Klin. Chirurg., Bd., Lxxv) upon the effect of the removal of the spleen and thyroid body, have given interesting disclosures concerning the function of these organs. During the experiments, extirpation of the spleen was alone well tolerated, but removal of the thyroid body was followed by strik- ing manifestations. The animals for two weeks refused nearly all food, were drowsy, walked with tottering gait, and died usually in convulsions. These effects were also manifested in animals which had survived the removal of the spleen, and from which subsequently the thyroid body was removed. In them was also observed an enormous increase in the number of white blood cor- puscles. In those animals from which the thyroid body alone was removed, the increase of the white blood corpuscles was not so remarkable as it was in those in which the spleen only had been extirpated. Ablation of the thyroid body produced notable anemia of the brain and hypertrophy of the spleen. The lymphatic glands, especially those of the mesentery, were’ frequently greatly enlarged and filled with black pigment. It, therefore, appears from these experiments that the thyroid body not only has the function of acting vicariously for the spleen, but also plays an important part in regulating the supply of blood to the brain, and may, in fact, be considered asa special organ for this purpose. Zesas decides from his experiments that the removal of the thyroid body is not justifiable (surgically), and his conclu- sions are strongly supported by the results of this operation per- formed by Kocher on man for the scrofulous degeneration of the organ.— Med.

Urea is thus decomposed into equal volumes of car- bonic acid and nitrogen which were easily estimated. It appeared from these experiments that the blood of the hepatic veins, splenic veins and the portal vein contains always more urea than the blood of the carotid artery, whence it is concluded that the abdominal viscera are the seat of continuous urea forma- tion. There was no notable difference in urea content between the blood coming from the head or the different members and that blood which entered those parts. . The chyle mixed with lymph drawn from the thoracic duct after death was always found richer in urea than either venous or arterial blood. . i The difference between the urea content of venous and arterial blood was much more marked in animals during the digesting than in the fasting condition. This agrees with the statement of Becker & Voit, who found the’excretion of urea much increased during digestion. It may be said that these observations are difficult to reconcile with the well founded belief that the liver is the principal organ for the formation of urea in the body.— Fourn. de l Anat. et Phys., 1884, p. 317. N THE SPECIFIC ENERGY OF THE NERVES OF THE SKIN.—The underlying facts of Joh. Müller's generalization that the nerves of special sense, as the optic, auditory, gustatory, filaments are en- dowed with specific energies cannot be disputed. What is meant is that any kind of stimulus whatsoever applied to the optic nerve arouses the sensation of light, every irritation of the auditory nerve gives rise to the sensation of sound, &c. The characteristic quality of these sensations depends not at all upon the peculiarity of the sensory nerve, but is determined wholly by the physiologi- cal properties of the nerve cells which receive the sensory impulse. From the skin, as a sense organ, we receive impressions that arouse in us at least two different kinds of sensations, those of pressure and of temperature, and it is an important question whether the impulses giving rise to these different sensations pro- ceed along identical nerves which reply in a different manner to differences in the quality of the stimulus, or whether the nerves of the skin are functionally differentiated in such a way as to call forth specific sensations without regard to the character of the stimulus. Weber believed that sensations of temperature and of Pressure were modifications of the same sense, depending upon the amount of energy aroused in the sensory nerve. Physiological analogy throws doubt upon this interpretation, and recently Blix has produced evidence which supports the view that the vane sensations aroused by excitement of the skin are as truly specific and due to the excitement of distinct nerves, as is the case with the other special senses. Blix used as stimulus the faradic elec- VOL, XIX.—NO, IV. 418 General Notes. [April, trical current. One electrode was fixed to the skin by a broad moistened contact, while the other electrode, used in exploring the surface, ended in a fine metal point. By graduating the strength of the current, sensory irritation was confined to the region of the pointed electrode. It was found that electrical stimulation of different areas of the skin produced different sen- sations. At one spot the irritation excited only pain, at another a sense of cold, at a third of warmth, at a fourth, it might be, of pressure. Hence, it may be concluded, that the quality of the sensation depends not on the nature of the stimulus but upon the specific energy of the irritated nervous apparatus. The author thinks he has shown that sensations of cold and warmth, respectively, are excited through different sets of nerves. The co/d nerves are broadly scattered over the skin and their endings are rather deeply buried in its substance. The w which alone we attain sensations of heat. A cold piece of metal, a square centimeter in section, laid upon a certain part of the fore- arm, produces no sensation of cold, while a pointed instrument of the same metal, at the same temperature, with a contact surface of only half a square millimeter, gives intensely cold sensations when applied to certain parts of the skin in the immediate neigh- borhood of the insensitive area —Zeitsch. f. Biologie, Bd. xx, p. 141: PSYCHOLOGY. INTELLIGENCE OF A SETTER Doc (Continued).—It is perhaps proper for me to here refer to the peculiar fancy of the bitch Frank. Barney was always her choice and strange as it may seem —with him there was no reciprocation. I have tested her pretty thoroughly, and I can say that she has not thus far permitted a dog not her own color to line her. And as a further proof a short time ago, being a few days before her season of heat, she left the farm seven miles distant upon which I had her kept and returned here. There are numbers of dogs in the neighborhood where she was kept, but she returned and when a dog of different color from her own was offered she would fight desperately. Although kept on the farm for several months this was the only time she had left it. Experimenting as I have with a number of dogs and bitches, I have noticed that some are very choice in their selection of a mate, while others are not. Some bitches will permit several to ne them, even without interval, while others will not have but one serve m. would not serve a wolf, Canis latræs, but Wad did. As a further evidence for comparison, showing the difference between the likes and dislikes of dogs, I give the following : Frank, as above stated, chooses a mate only of her 1885.] Psychology. 419 A dog more mischievous or one more noted for his original pranks, I never owned.’ Many of the little things usually taught a dog were not to his liking, and for this reason would at times bring harsh words upon him, but for originality I have not known his equal. He had been taught to carry quite heavy loads of shells for me into the field to use in hunting, and in this manner he was much strengthened in his jaws. It was an easy task for him to pick up a twenty-five pound sack of shot and carry it a hundred or more feet. One time he surprised me in this feat, for I had used a sack of shot to tie him to in the office. Frank was also tied to another sack near by. I picked up the sack of shot she was fastened to and led her to another part of the office, to another room. After a few moments Barney came in carrying his sack of shot. I had not intended moving him but this ingenuity was too much in the dog’s favor, he was permitted to remain. While hunting it was a common practice for him to stand in front of me when shooting from a point, stand or blind, and while I could watch all birds that came towards me, he would give me signal by the expression of his eyes and movement of his head from which way I could expect the best shot, and many times I have waited until from his signs it was evident the birds were in close range, then turning around rapidly make a good shot. In hunting small birds he was exceptionally fine, for when out with me collecting specimens, as I would crawl along closely watching the habits perhaps of some minute bird, he too would walk as stealthily as a cat and many times he has by his cau- tious actions, a look up into the tree or a wag of his tail, called my attention to one or more birds I had not as yet noticed in the tree six months of age I began the field, this he did quite for him to find them, but | 420 General Notes. [ April, He had no appreciation of the fact that that very small bird could have been swallowed, but as I saw him do it, there was no doubt on my part. Forsome minutes he labored to find that bird, even going to the bottom of the ravine, and I to change his thought shot another bird which fell into the ravine and was retrieved by him. Another time when his facial expression was very fine, was at a time when he caught a wounded duck that had fallen near me, and while he had her in his mouth I shot another duck, and this second one also falling very near me and the dog Barney opened his mouth and the bird he had in it flew away. Without taking his eyes off the fleeing duck he watched until she had lighted upon some high land away from the water. The next day I put him to work upon the high land to find the duck, and never did I see him more pleased than when he brought the duck yet alive to me. To give a statement of all the various strange proceedings of this dog would take too much space, for they are many, but to close I will give what perhaps was his last attempt to outwit me and to gratify his own high intelligence. While collecting birds and animals in Dakota in the fall of 1883, near the close of the season I shot a muskrat in one of the lakes. Barney went out to where it was, in shallow water upon a sand bar, rolled it over with his foot and came towards me without it. Speaking harshly to him he returned picked up the rat and brought it to me on shore. Going towards camp I signaled him to bring the rat with him; after a few moment she complied, and as he trotted along by my side for some distance in apparently high glee I thought no more about him until I got to camp, then look- ing around for him I could not find him.

H. Talbot. AN AFFECTIONATE ANGORA Cat.—A, Espagne gives to the _ Kevue Scientifique a story of a half-breed Angora cat of exceed- ing docility and affection. During about fifteen days of every 1885. | Anthropology. 421 year this cat left the house, ignored the calls of its owners, and led a wild life around the neighborhood. At the end of this time it returned, and was demonstratively affectionate. It was particularly attached to the aged head of the household, was always at his side or on his knee during the day, and at night slept at his feet. When he died, the cat mewed ina sad monotone never before heard from her. Four years afterwards a baby, to which the cat had transferred her affection, was taken sick and died. During its illness the cat remained most of the time below the cradle, ate little, and lost the brilliancy of its eyes. On the return of the family from the country the cat lay dying in its ac- customed place, and was found dead in the morning. Though age and the cold wave which took the infant’s life may have had their share in the matter, it yet seems that sorrow was the imme- diate cause. C. Jamelin gives a story of a charitable Angora cat of magnifi- cent presence, but not usually very intelligent. This cat many times brought home a hungry cat as if to obtain food for it, and finally maintained a regular pensioner. The first time the estray was brought, the Angora mewed and jumped around till food was given to it, watched it while eating, and then accompanied it to the door, hastening its departure with a series of light quick pats. The strange cat learned the lesson, and often came again as a visi- tor but not to stay. INTELLIGENCE OF TorTorses.—Anecdotes in the Revue Scien- tifigue appear to show that these creatures must be credited with a considerable amount of intelligence. M. Boucard writes of one which lives in his garden, and, when called aloud by its name, Laideron, would immediately run towards the voice with all the speed a tortoise can muster : The Testudo mauritanica of M. Boisse showed even more intel- ligence, learned to come when called by a hissing sound, followed its master like a little dog; relished caresses bestowed on its head and neck, gave gentle bites to show its affection, and would climb upon its master’s boots or pull at his clothes to draw his atten- tion.

[April, have been shot in open holes or “ leads” of water, within darting distance from the edge of the ice. The Eskimos call it “ aú- lt-gt.” It consists of a long light shaft (¢-pz-@) of wood, about one inch in diameter, and generally about five feet long, though the Jength varies with the height of the man who uses it. The butt of this is armed with a slender bayonet-shaped ice-pick (¢#-~) of walrus ivory, about fourteen inches long, and to the other end is securely fastened a heavy pear-shaped foreshaft (u-ku-mat-lu-ta, “ weight”’) of walrus ivory or compact bone, which serves to give weight to the head of the harpoon and make it fly straight. It is about five inches long and an inch and a half in diameter at the forward end. In the center of the end of the foreshaft is a deep round socket into which fits the butt of a slender rod of ivory about two inches long, the “ loose-shaft”’ (¢-gi-mz). This is secured to the foreshaft by a thong passing through a hole drilled in it, so that it can be easily removed from the socket, while the thong prevents it from being dropped and lost. On the tip of the loose- shaft fits a detachable toggle-head (maz-/#) of the ordinary type common to the whole Eskimo race, provided with a long line of seal thong upwards of ninety feet in length. When ready for use the line is drawn taut from the head to about the middle of the shaft, made fast by a couple of half- hitches, and kept from slipping by a little ivory peg (4z-/er-dwif) inserted into the shaft. Just back of this there is also a little curved ivory knob (#-£a) secured to the shaft as a rest for the forefinger in aiming the weapon. e hunter on starting out carries his rifle slung in a sort of holster across his back, and secured to this the zaú-¿ú and line folded in long hanks. The rest of the harpoon is carried in the hand and serves as a staff in walking and climbing among the ice-hummocks, where the sharp pick is useful to prevent slipping and to try doubtful ice, and also enables the hunter to break away thin ice at the edge of a hole so as to draw his game to the solid floe. It can also serve as a bayonet for defence in case of neces- Sy. When a seal has been shot and floats, the zaú-ľû and line are fitted on and the weapon darted with the right hand while the left holds the end of the line. The maz-/é enters the animal en- tirely, and a pull on the line causes it to slip off the top of the loose-shaft (which is facilitated by the play of the latter) and to oere securely under the skin. The whole is then drawn in by e the line. The use of this weapon appears to be éonfined to Northwestern ; ` Alaska, and it is very rarely found south of Bering’s strait. In the large collection made by Mr. E. W. Nelson in the neighbor- hood of Norton sound, there is only one rather clumsily-made naúlīgů, with a fragment of the line, which is labeled a “ beluga 1885.] Microscopy. 425 spear.” It is manifestly unfitted for such use, but this statement goes to show that it was an unfamiliar weapon among the people by whom he was surrounded. The natives of that region, as well as the Greenlanders and Eastern Eskimos, retrieve seals with the kaiak, occasionally using the stabbing harpoon common to the whole Eskimo race, to secure a seal, but they are unprovided with any special weapon for retrieving. We were unable, during our stay at Point Barrow, to ascertain whether this weapon was in use before the introduction of fire- arms, which are now universally employed, but I am strongly led MICROSCOPY."

Huxley’s course deals with the mor- phology and physiology of a few typical vegetable and animal organisms; Carnoy’s course deals with the chemistry as well as the morphology and physiology of the cell, as the structural unit of all organisms. The one makes.use of both macroscopica and microscopical methods of observation; the other employs - almost exclusively methods of microscopical technique. The Prac- tical Biology pursues methods of its own, and aims to impart, through laboratory work, such information as should form a part of so-called general education; the Cellular Biology limiting itself to a single subject of general and fundamental importance, proposes to deal with it in an encyclopedic fashion and thus to lay a broad and solid foundation for special study in botany, zodl- ogy, or physiology. The former points out the direct way to a system of facts, and deals very sparingly in interpretation; the latter adds to its facts and methods, history, discussion, and gen- eral interpretation. The English manual is an excellent guide for the general student, who merely desires some knowledge of typical organisms ; but the training it offers, though admirable as far aş it goes, falls short, in some important particulars, of being an adequate preparation for original investigation in either of the above-named departments of biology. The French manual, if completed with the thoroughness that characterizes the first num- ber, will furnish, in our opinion, not only a much-needed book of reference, but also a course of study which exactly meets the needs of those who are preparing for independent work. _ The general scope of the work may be seen from the following introductory remarks by its author: “ A course in general cyt- ology should embrace the study of both the animal and vegeta- ble cell. * * * The essential characters of organization, and the fundamental biological laws, are the same for all living beings. * * * It is only after having searched the two kingdoms, after having followed the organized element step by step, and through 1885.] Microscopy. 427 the entire series of living forms, that it becomes possible to gain a conception of it, which can be called exact, truly scientific and fruitful. “ Cytological instruction should be complete and searching. In order to be complete, it should survey the cell from all sides, from the standpoint of morphology, anatomy, physiology and bio- chemistry ; for it is under these several aspects that it will serve as a basis for subsequent study. In saying that it should be searching, we should take care to demand that it be encyclope- dic; a course which loses itself in details would not be thorough. What we desire is, that the student shall be made to penetrate into the inner life of the cell, and actually to lay hold of both the essential and accidental chemical constitution of living matter, the fundamental organic constitution of different parts of the cell— membrane, protoplasm, nucleus; to reflect long upon the principal physiological phenomena—indispensable foods, elaboration, diges- tion, assimilation, &c.; upon the general movements of the cell— cleavage, fecundation, different movements of the protoplasmic reticulum; upon differentiation, cellular geotropism and heliotro- pism,” &c., &c. The first part of this first number of the work containing 167 pages, is devoted to the instruments and methods of microscopi- cal research. The first of the three books into which it is sub- divided, treats of the microscope and its accessories, the microspec- troscope, polarizing apparatus, the micrometer, goniometer, pho- tographic apparatus, and camera lucida; and closes with a chapter on the laboratory, aquaria, and reagents. The second book considers the objects or materials of study, and the methods of preparation, including the microtome and its uses, : The third book devotes one chapter to “the education of the eye,” another to “the examination and treatment of prepara- tions,” and a third to “the method to be pursued in scientific re- searches and publications.” oo ae The second part opens with a valuable historical preliminary, and a discussion of general notions of the cell, including termi- nology and definitions. Then follows a book of sixty-five pages devoted to the zucleus—its chemical constitution, structure, and morphography. The remaining three books of this part, dealing with protoplasm, the eT and general discussions, will a r in the second number. "The historical summaries, and well-arranged bibliographical references, form a very valuable feature of the work; and the same may be said of the chapters devoted to methods of research, which contain much that is new. The cuts are a// original. They are well executed, and for the most part well chosen ; but this is a point in which originality might have been curtailed we selected illustrations borrowed from different sources. 428 General Notes.

' Metuop or MAKING ABSOLUTE ALcoHnoL.—Dr. Sharp states that absolute alcohol is prepared in Ranvier’s laboratory by add- ing anhydrous cupric sulphate to ninety-five per cent alcohol.? Pulverized cupric sulphate is heated to red heat in order to drive off the water of crystallization ; when cool the white pow- der is placed in a wide-mouthed bottle, holding about a liter, and three-fourths full of alcohol. The bottle is quickly closed and the whole shaken. After standing a day or more—with occa- sional shakings—it is decanted and the operation repeated, espe- cially if the cupric sulphate shows much of the blue color due to the reassumption of water. ; As a test a drop of the alcohol thus dehydrated may be mixed with a drop of turpentine on a glass slide, and examined under the microscope; if no particles of water are to be seen the alco- hol is absolute enough for all practical purposes. 30% SCIENTIFIC NEWS. * character of the bottom.

STOKES, M.D. BITTER November wind out of a gray sky. A river as gray and cold, a little foam on its surface where the rocks fretted it. A group of bare trees ankle deep in their own leaves on a low bank whence bubbled a rill that seemed the only happy thing in the dreary landscape, while a shivering pedestrian shed involuntary tears as he filled his bottle with wet leaves and with water from the brook. A gloomy prospect anda gloomy day, but for compensation that bottle held a potentiality of infusorial wealth beyond the dreams of avarice. Nota tithe of the won- derful forms developed from the germs in that natural infusion could be noticed without making a paper of wearisome extent. To enumerate the individuals would be impossible. I can only present a half dozen taken at random. As the infusion stood through the winter in a covered vessel, to which not a single drop of water was added except by the con- densation of its own vapor on the cover, a source of endless in- terest to the writer has been to observe the sudden disappearance of the creatures which, for a week or two, had swarmed among the leaves by the thousand, and the equally sudden coming, from unsuspected and unknown spores, of as great a crowd of entirely different, more complex and more highly organized animalcules, Those higher in the scale devoured the lower, it is true, and did it without ceremony ; but many died and melted away as their favorite food became exhausted or, for some other problematic reason, their surroundings became inauspicious. For weeks microscopic fungi flourished until the surface of the water bore a jelly-like layer a quarter of an inch deep, and Hypotrichous In- fusoria, so huge that they were distinctly visible to the unaided vision, sported there in leaderless regiments and cohorts. But even that collection of fungi and bacteria disappeared, and the ¥ 28 434 Some New Infusoria. [May, water at this writing is as clear and limpid and sweet as that of a mountain spring, and not one of those gigantic Hypotricha is left. Yet the bowl is still a crowded infusorial menagerie. And not the least interesting fact is that most of those that have died as well as the living are new to science. The lowest of those to which I desire now to refer, and per- haps the least abundant in its habitat, is a new member of the genus Atractonema, the threaded spindle, of Stein. Hitherto but one species has been observed, and that only by its discoverer. With it the body is much more fusiform than with this American animalcule, but the latter possesses all the generic characters of its foreign relative, and others which mark it as specifically dis- tinct. The mouth in-both is conspicuous, being especially so in this new form. The pharyngeal passage it is scarcely possible to overlook since it seems to communicate directly with the contrac- tile vesicle. Whether the food passes into the pulsating vacuole, or through it, or to one side, are questions of interest that, so far as I am concerned, remain unanswered, as the creature has refused to take food when on the microscope stage. The single flagellum arises within the pharyngeal passage, a point on the wall, presu- mably the roof, serving as the basis of attachment. This struc- tural feature is not mentioned, and probably does not exist in Atractonema teres Stein. The motion of the flagellum is very rapid, consisting of oscillations which give it the appearance of a figure of eight. That it is held stiffly coiled in that position and then vibrated, as is represented in the sketch (Fig. 1), I have been unable to determine. It has been engraved in that position because I desired to show the animalcule in its characteristic swimming attitude. When the Atrac- tonema has been poisoned, preferably by iodine, pref- erably, of course, so far as the observer is concern the flagellum is uncoiled and straightened. The fig- ure of eight aspect may therefore be illusory. The animalcule’s movements are by rapid writhing and twisting, at the same time rotating on its long axis. It is not changeable in shape, preserving its elongate, subcylindrical, somewhat vermicular form, Fic. 1,.°*cePt when in the agony of a toxicological death.

C/z/omonas paramecium Ehr., for a long time the prevailing animalcule in the infusion, contains similar bodies which, under the influence of iodine, become intensely blue, and are therefore probably amyla- ceous. Those within Atractonema, under similar circumstances do not so change. The reproduction of the European species is by longitudinal fission. Multiplication of the American form has not been observed. Fig. 1 and the following description will probably be sufficient for diagnosis: Atractonema tortuosa, sp. nov.—Body elongate, subcylindrical, soft and flexible but persistent in shape, seven to ten times as long as broad, tapering and pointed pos- teriorly, the anterior extremity narrowed, the frontal border truncate; oral aperture terminal, conspicuous, followed by a tubular pharyngeal passage apparently con- nected by its posterior termination with the spherical contractile vesicle ; flagellum single, vibratile, about one-half as long as the body, issuing from the oral aperture and taking its origin from the wall of the pharynx at some distance from the frontal argin; nucleus ovate, placed behind the body-center; endoplasm colorless, trans- parent, enclosing numerous, oblong, dark-bordered corpuscles; movements tortuous and rotatory on the long axis. Length of body ;45 tos}; inch, Habitat: a vege- table infusion, In the American Journal of Science for July, 1884, the writer described two new species of fresh-water infusoria under the gen- eric title Solenotus, which was subsequently ascertained to be preoccupied in the Hymenoptera. Consequently, in the August number of the same journal, the name was changed to Notosol- enus, the two members of the genus then being Notosolenus (Solenotus) apocamptus and N. orbicularis. The chief character- istics, aside from the persistent shape and an oral aperture, are the presence of a very short and inconspicuous trailing flagellum on the convex or ventral surface, and a longitudinal depression traversing the dorsal aspect, the infusorian thus appearing to swim on its back, since that part is expected to be more or less convex. Here, however, it is the ventral surface that is rounded. When these animalcules were first obtained, although an anal aperture was observed and its location recorded, an oral orifice was not noted, and the systemic position of the infusoria was assumed to be among those forms which take food through any point on the surface, and near to Stein’s Colponema. Since then, however, numerous specimens of both species have been observed, and although an oral aperture has not been actually discerned, yet the appearance of what seems to be a short pharyngeal tract is so constantly present that an oral orifice probably exists, and 436 Some New Infusoria. [May, the animalcules must therefore demand admission to the Flagel- lata-Eustomata of Saville Kent. The indurated character of the cuticular surface and the presence of green particles, apparently of food, within the endoplasm, would indicate the existence of a special mouth which would also be indirectly suggested by the appearance of the anal opening. The place of the genus in a systemic arrangement would therefore probably be, not in the neighborhood of Colponema but near Dujardin’s Anisonema, differing from the latter, so far as the flagella are concerned, in having the shorter the trailing one, and the longer the vibratile, the converse of this being characteristic of Anisonema. In the infusion a third species of Notosolenus has appeared. _ It is much depressed and almost triangular in form, the sloping sides being somewhat concave or undulate, and the truncate pos- terior extremity more or less emarginate, this emargination in some individuals increasing to a strongly marked concavity. Fig. 2 represents the creature in its ventral aspect with the extremity moderately uneven, and Fig. 3 another individual with a con- Fig. 3: Fic. 2.—Wotosolenus sinuatus, sp. nov., ventral, FIG. 3.—/. sinuatus, emarginate form, ventral. spicuous emargination. Its endoplasm is very bright and transpa- rent, being obscured only in the posterior part by granules and food particles. Its movement is forward in an almost direct _ course, the body elevated, the anterior apex in contact with the slide, the long flagellum held stiffly and obliquely in advance, its free end only vibrating, while the short flagellum, which appears _ to be of but little practical advantage to its owner, trails almost _ motionless below or above, for whether the animalcule shall float with the dorsal surface upward or beneath seems immaterial. It 1885.] Some New Infusoria, 437 advances across the field of view, stopping at any collection of débris in its path, examining it for food and departing with sud- den turns and reversals of its course. The appearance of a pha- ryngeal tract is here more clearly defined than in the other spe- cies, and the infusorian is by far the largest of those hitherto ob- serv Notosolenus (Solenotus) sinuatus, sp. nov.—Body pee broadly and irregu- larly ovate or subtriangular, somewhat longer than broad, widest posteriorly, grad- ually tapering through the posterior two-thirds, thence tanidi narrowing to the rounded frontal margin, the lateral borders frequently concave or undulate, the pos- terior extremity truncate, more or less emarginate; dorsal depression narrow, deep, with an anterior keel-like elevation; ventral surface smoothly convex; long flagel- lum vibratile at its distal end only, somewhat less than twice as long as the body, held stiffly and obliquely in advance towards the right-hand side; short or trailing flagellum about one-half as long as the body, usually extending obliquely backward toward the right-hand border; nucleus apparently single, spherical and near the center of the left-hand side, the contractile vesicle in front, and near the beii margin; endoplasm colorless, Etir gerig enclosing granules and green particles. Length of bo B 114z, greatest width inch. Habitat: standing water, with dead lea When the wi of fungi and bacteria on the water was near its height, a Paramcecium appeared in profusion. It seems to be a distinct species, and one that can scarcely be mistaken for any known form, except possibly for P. dursarta (Ehr.) S. K., differing from the latter, however, conspicuously in form, especially in the apparently oblique curvature of the anterior extremity, in the absence of the truncation of the same part, the absence of the rapid and continuous circulation of the endoplasmic contents, and particularly the green coloration of the cortex and sarcode. The oral aperture of the form I have named Paramecium trichium is at the posterior extremity of the deep adoral fossa which gives the front part the appearance of being folded toward the left, and is followed by a distinct, ciliated pha- rynx (Fig, 4). The two contractile vesicles, instead of being placed one in each body- half, as in P dursaria, are here anterior and close together, contracting quickly, the one beginning to reform almost before the com- yg gS Fig. 5. pletion of the other’s systole.

[ May, body. When forcibly extruded through the influence of the glycerole of tannin, the distal end of each, for about one-tenth of the entire length, is conspicuously thickened, so that the tricho- cyst seems to be supplemented by the addition of a minute pyramid (Fig. 5). Occasionally, before the animalcule’s death, when suffering from the application of a very dilute solution of the glycerole, it then gradually assuming an evenly ovoid form and becoming pale and ghostly, and always after the extrusion of the trichocysts and their removal from the body, the cuticular eleva- tions are replaced by equally minute, regularly disposed, parallel- ogrammic depressions, as if the escaping trichocysts had left empty spaces which were filled by the sinking of the cortex. The nucleus and nucleolus are not always constant either in rela- tion to each other or to a special part of the body. The former is sometimes, and normally it would seem, subcentrally located, yet sometimes being near the dorsum, again nearest the ventral surface, and still again in the anterior extremity, being seldom seen behind the body center. The laterally attached nucleolus is almost as uncertain in its relative connection with the nucleus, becoming at times entirely detached. Conjugation has been observed, union taking place between the latero-ventral surfaces. Reproduction is by transverse fission, the nucleus previously becoming much elongated, the dividing plane passing through its center. In some instances, soon after the beginning of genetic union, the nucleus assumes a finely striated appearance, gradually growing more and more indistinct in contour until it finally becomes indistinguishable from the sur- rounding endoplasm.

The sheath or zoocytium is very soft and shapeless, and variable both in size and in number of its occupants. It appears to be formed primarily by a thin exudation from the creature’s body that would be nearly invisible were it not for the extraneous par- ticles, spores, bacteria and débris of all kinds that adhere to the surface, and especially for the zodid’s excrementitious matter which seems to be the principal building material and the cause of the coarsely granular aspect. It is not uncommon to find a small colony produced by the mutual union, and probably by a mutual formation of adjacent zoécytia, the resultant of this adhesion being a non- descript mass of flocculent matters from under shelter of which the animalcules project, and when startled by the approach of a larger infusorian, or from other cause, quickly glide backward to the posterior part of their semi-transparent dwelling. These zoöcytia are frequently attached to vegetable fragments or to masses of residual detritus so that they would be an almost in- distinguishable part of the granular ‘aggregation were it not for the presence of the living infusorian. Indeed, when deserted these formations cannot be separated by the eye from other floc- culent clusters so often in the field. Yet the creature forms them, apparently involuntarily, for soon after a frightened zooid comes to rest, rejected particles in the food-bearing current begin to mark the outlines of the mucilaginous excretion which soon increases in size by the adhesion of everything that touches it.

On such occasions the surface cilia behind the position of the oral aperture are in only irregular and uncertain vibration, while those on the frontal border, including the curved fascicle, are in the most active motion, being only momentarily visible, the right-hand ciliary fringe, under an insufficient ampli- fication, then presenting the aspect of a single short seta, or a narrow lip, projecting from the posterior angle of the excavation. When the zodids have been for some time under the thin cover, they voluntarily leave the old zoocytium, swimming rapidly and occa- sionly settling on the slide to form a new and equally structure- less protective covering. If a-convenient collection of miscella- neous debris is accidentally encountered, the wandering infusorian often takes refuge beneath it, there gliding backward when threat- ened, as it did so conspicuously in its original home, the long anterior cilia then streaniing out at the front. Cyrtolophosis (kuptos, curved ; hogwats, wearing a crest), gen. nov.—Animal- cules ovate, persistent in shape, entirely ciliate, the adoral cilia differing from those of the general surface, the anterior extremity bearing a fascicle of long distally curved, vibratile hairs ; secreting and inhabiting a variously modified, mucilaginous, granular zodcytium, to which they are in no way attached and from which they may pass at will; oral aperture at the posterior extremity of an excavated, elongated groove, Tongia traversing the anterior part of the ventral surface, bearing on its right-hand’ margin a series of cirrose, adoral cilia; nucleus and contractile vesi- cle single, conspicuous; anal aperture postero-terminal. Cyrtolophosis mucicola, sp. nov.—Body ovate, two and one-half to three times as long as broad, both extremities rounded, narrowed anteriorly, the ventro-frontal bor- der obliquely truncate; anterior cilia longest, those of the Aey surface setose, the anteriorly placed fascicle of distally and downwardly curved cilia conspicuous; adoral depression extending from the frontal border for densi the length of the entire body; adoral cilia cirrose, curved, diminishing in length toward the oral aper- ture; contractile vesicle single, spherical, posteriorly placed near the oat -hand lat- ` eral border; nucleus subspherical, subcentrally located. Length of body 3,5 to toss inch. Zodcytia solitary or variously united. Habitat: an infusion of dead leaves. Reproduction by transverse fission. Another infusorian, bearing a carapace and having the adoral fringe on the left-hand margin of the peristome, and therefore undoubtedly a member of the Euplotide, proved to be an unde- scribed species of the curious Euplotes, animalcules whose ven- tral styles are not only used for swimming but as ambulatory _ organs. They are often seen walking over the slide and among the masses of débris usually present, apparently swimming only when food is exhausted in that locality and they must journey * 188 5.] Some New Infusoria. 441 further to seek it. The form now referred to differs from all others in the number of the frontal styles, the character and arrangement of the anal styles and caudal setz, and in the shape of the carapace, which has a very conspicuous keel or high acute ridge traversing the dorsum from the frontal to the posterior borders.

Through the kind- ness of Dr, Packard I am able to present here a corrected draw- ing (Fig. 9) of the same interesting infusorian with the descrip- tion. My pleasure in doing so is increased not oniy by the 442 Some New Infusoria. [May, opportunity to correct my own oversight, but because I can again ask attention to one of the most beautiful American members of the genus. The carapace of Æ. carinata is somewhat irregularly marked by small circles formed of minute dots visible through the trans- parent borders. This ornamentation is variable, however, as is probably the case in all the decorated species, the dots becoming scattered, leaving the little circles incomplete or even entirely de- stroying them. This variableness in the surface adornment is also apparent in £. plumipes, but there, when most completely developed, the ornamentation consists of oblong elevations ar- ranged in stellate clusters which are sprinkled quite regularly in Fig. 9.

The result is very pleasing to the eye, and adds another item of interest to the infusorian which seems to be one of the bravest and most self-reliant of its class, walking or swimming boldly and steadily forward as if with some object of vital import in view. This ornamentation is shown in detail in Fig. 10. Euplotes plumipes Stokes.—Carapace irregularly suborbicular or elliptical, the an- _ terior margin trunca! te, often minutely crenulate or beaded, the upper lip crescentic oe Dai bade: commonly obliquely truncate in opposite directions and forming cen- ` trally a projecting and rounded angle or keel-like protuberance ; peristome field 1885.] Some New Infusoria. 443 wide, triangular, the upper right-hand corner prolonged in a sinistrally directed heli- coidal curvature, posteriorly extending beyond the center of the ventral surface, the cilia of the anterior and left-hand borders large and cirrose, the posterior third of . the right-hand margin ciliated; six frontal, three ventral and five anal styles, the extremities of each of the last finely fimbriated; caudal setæ four, the two on the right-hand side of the median line much branched; dorsal surface convex, without longitudinal furrows, minutely roughened and often ornamented by longitudinal rows of equidistant elevations formed of minute prominences arranged in stellate clusters; nucleus band-like, curved, very long, extending around nearly the entire periphery, its extremities separated by a short interval near the right-hand body margin; anal aperture in close proximity to the contractile vesicle. Length of cara- pace sj}, inch. Habitat: pond water, near the bottom. Conjugation is accomplished through the union of two indi- viduals by the left-hand half of the ventral surfaces, and multipli- cation is by transverse fission. The first apparent change pre- ceding the latter act is the development of a series of cilia almost parallel with the left-hand margin of the peristome, while from the comparatively vacant space over which the ventral styles are scattered, the zodid gradually extrudes fourteen new styles, a second contractile vesicle appears, and the infusorian then pre- sents the interesting aspect of a Euplotes with a double row of adoral cilia, two pulsating vacuoles, four caudal sete and twenty- eight ambulatory styles. The body quite rapidly elongates until about twice the ordinary length, and separates across the middle, distributing the twenty-eight styles so that the anterior moiety preserves the old frontal and ventral ones, taking five of the new for its anal supply and extruding four fresh caudal sete. The posterior portion therefore has the newly formed frontal and ven- tral and the old anal styles, with the old caudal sete. But before the final separation the posterior animalcule extrudes four addi- tional caudal setz, then having twice as many as the normal complement, gradually and in irregular sequence absorbing the four old and now unwelcome and useless ones, those that are branched being the last to appear and the last to be absorbed. 444 Kitchen Garden Esculents of American Origin. (May, KITCHEN GARDEN ESCULENTS OF AMERICAN ORIGIN. I. BY E. LEWIS STURTEVANT, M.D. N our leading seed catalogues some seventy-two species ot plants are usually grouped under kitchen garden esculents. Of these we believe seventeen to be of American origin, the purslane doubtful, and chives to belong to both the old and the new world. Excluding these nineteen, De Candolle assigns, of the remainder, twenty-four tq Europe, fifteen to Asia, four to Africa, one to Australasia and nine not mentioned. Of this list many have both European and Asiatic habitat, or other habitat as well as the one under which tabulated. If we compare the im- portance of the old and new world vegetables, we find it difficult to decide. Certainly the old world cabbage, in its numerous races, is of importance in the garden, but so is the new world potato. What can be decided, however, is that the peppers, pumpkin and squash, tomato, sweet corn and sweet potato are representatives of a culture which antedated their introduction into the gardens of Europeans, and must have been derived through a cultivation as careful as was required for the equal development of similar vegetables of old world origin. To ex- pect to find the original of our longest cultivated vegetable pro- ducts, as wheat or maize, in a plant that can now be recognized as a wheat or a maize, seems unphilosophical, as evolution must have long since produced changes during that long series of selections that have resulted not alone in producing varieties, but even races which deserve specific discrimination. On account of the light thrown upon an ancient civilization by the knowledge of the cultivated plants it has produced, I have thought fit to bring together a selection from my notes relating to the esculents of American origin which are now to be generally found in our = vegetable gardens. Alkekengi—The alkekengi, or more usually called strawberry tomato in our seed catalogues, is Physalis pubescens L., an Amer- ican plant which furnishes one of our minor vegetable products. - This plant is said by Gray to be common southward and west- _ ward in the United States ; and it is the camaru of Brazil It is 1 Masters, Treas. of Bot. 1885.] Kitchen Garden Esculents of American Origin. 445 described by Parkinson’ under the name of Hadicacabum f. alk. virginiense, and by Feuille? under the name of Alkekengi virgini- anum fructu luteo these names indicating its American origin. P. peruviana Hort., the alkekengi of Peru or Capuli, is cultivated in French gardens, but it differs but slightly from P. pubescens Pickering’ says it is a native of tropical America, and has a Carib name, sovsovrov-scoroo (Desc.), and is called in Tagalo potocan (Blanco). Mueller® says P. peruviana L.,.is a native of temperate and tropical America, and is now naturalized widely in many coun- tries of the warmer zone, a perennial, but in colder climates an an- nual. P, barbadensis Jacq., is another species sometimes cultivated in France’ and a native of Barbadoes.’ P. mexicana Vil., probably synonymous with P. edulis Sims., is grown in France, and the seed sold under the name of petite tomate du Mexique, accord- ing to Vilmorin (l. c.), but as grown at the New York Agricultu- ral Experiment eae it appears to answer to the description of P. angulata L. (var. ? philadelphica Gray ?), but the fruit larger than in the description. If this supposition be correct it was mentioned by Camerarius in 1588, Parkinson 1640, etc. Sloane mentions its occurrence in Jamaica.” Pickering” says it is a native of tropical America, but it seems to have a Malabar name, znota inodien (Rheede), Burmese pungben (Mason), Ylocano tuttullacac (Blanco), on Tahiti zamani (Bertero), on the Hawaiian islands kamani. Mueller™ says it occurs in many tropical countries, ex- tending as a native plant to the northern part of the United States and to Japan. The old world alkekengi is P. alkekengi L., ‘well known to the ancients, and described by Dioscorides. It does not now seem to be cultivated as a kitchen garden plant, having been super- ceded by the American species. The fruit of the strawberry tomato is much esteemed by some 1Theatrum Botanicum, 1640, 462. 2 Obs. faites sur les cotes orientales de Amerique meridionale, Paris, 1714-25. 3 Miller’s Dict. *Vilmorin.

(May, people in a raw state or in preserves, and is disliked by others. It has a sweet acidulous taste with a pronounced flavor, considered by some as agreeable, by others as nauseous. It was not known in French kitchen garden culture in 1829 (not being mentioned in L'Hort. Francais, 1824-5, Nouv. Dict. du Jard., 1826, nor by Noisette, Man. du Jard., 1829), nor was the seed in the catalogue of Thorburn in 1828, which would indicate that it was not then in American gardens. P., alkekengi, according to Loudon, was cultivated in most gardens in England till in the last century, and he says several other hardy species, including P. pubescens, also produce edible fruit. Alkekengi is described in several varieties or species by Burr in his American “ Garden Vegetables,” edition of 1863, but I have no opportunities of library conveniences to establish when our — first appeared in kitchen garden culture. Bean: Kidney —We have few vegetables as difficult to trace historically as the common bean (Phaseolus vulgaris Savi.), on account of the confusion which exists not only in the vernacular names customarily applied to this group of the Leguminose by common people, but also on account of the likeness which ap- pears to exist between deans of various botanical genera. Ina finely arranged museum collection of substances used in the arts, and arranged by a gentleman of unusual scientific attainments, I very recently was much surprised to recognize the Soja bean under the name “ Beans from Japan,” and also to recognize a variety of Dolichos under a similar mislabeling. The bean serves as a food, and is carried as provision from place to place without destruction of its value as a seed, and hence we should expect a more rapid and less recorded introduction to a new locality than is generally the case with a desirable vegetable, and this quick distribution is illustrated by the mention, by Josselyn, one of the early writers of New England, of the “ American beans ” of many kinds, and also Bonivis, Calavances and the “ 4idney-bean that is proper to Roanoke,” and he adds: “ But these are brought into the country; the others are natural to the climate.’ In De Candolle’s writings upon geographical botany, he seems to ignore authors who might be quoted to fortify an opinion upon the American origin of plants, as his references show dependence ` 1 Hort. Lond., 1860, p. 582. _ *Josselyn’s Voyages, pp. 73-74. 1885.] Kitchen Garden Esculents of American Origin. 447 more upon botanical writers than upon mention by voyagers and historians. If we peruse the early accounts of American discov- ery, we find beans mentioned as of almost universal occurrence among the native tribes, but what bean was meant must be in- ferred from other data. In the north-eastern portion of America it is probable that such mention is of Phaseolus vulgaris; in the central portion, of this and some species of the Dolichos ; further south, the Dolichos and lima are perhaps often included; in the south-west, the mesquit bean. All these sorts, whichever genus was intended, served as food for the traveler, and were doubtless, all but the mesquit, secured as provision by the many exploring vessels victualed in those times from the productions of the coun- tries visited. We have absolutely no certain information which leads us to suppose that Phaseolus vulgaris existed in the old world before the discovery of America. The only evidence we find is the early use of the word “kidney-bean” by voyagers, as when Columbus, in 1502, found “ red and white beans, resembling the kidney-beans of Spain,”? but this is in a translation; or when Strachey says the beans of Virginia “are the same which the Turks call garvances ;’” but Strachey was in Virginia in 1610, and before this the kidney-bean seems well known in Southern Europe. There is no certainty that it was known to the ancient Greeks and Romans. According to De Candolle? this bean is not among the numerous seeds that have been unearthed from the ruins of ancient Troy, nor has it been found in the lacustrine débris of the lakes of Switzerland, Savoy, Austria and Italy. There is no proof that it existed in ancient Egypt. It is not mentioned by ancient Chinese authors. The authors of the fifteenth century, such as Crescenzio and Macer Floridus, do not speak of it. The authors of the sixteenth century, after the dis- covery of America, all publish figures and descriptions of P. vul- garis with an infinity of varieties.’ Kidney-beans are stated to have been introduced into England " 1597, some say imported from the Netherlands as early as 1509.° French beans are, how- 1Knox.

[ May, ever, mentioned by Barnaby Googe in 1572, which name indi- cates their previous introduction into France. In 1640 Parkin- son? says in his quaint form: “ There hath come likewise unto us and others both from Africa, Brasill, the East and West Indies, Virginia, &c., sundry other sorts and varieties which were endless to recite, or at least useless, but onely to behold and contemplate the wonderfull works of the Creator in those his creatures.” The mention of a Faseolus by Albert le Grand, which De Candolle takes to be a dwarf bean, may well apply to some species of Dol- ichos, probably D. umguiculaius L. There is no indication of an early introduction into India, as De Candolle remarks, and Wal- ter Elliot* says that P. vulgaris is not an article of field produce in Southern India nor of general use among the natives, its cul- ture being confined to gardens near European settlements. The evidence for the antiquity of the bean in America is both circumstantial and direct. The number of names given in the northern parts of America alone indicate an antiquity of culture, such as sahe or sahu on the St. Lawrence (Cartier), ogaressa by the Hurons (Sagard), éwppuhguam-ash, “twiners,’ by the North- ern Algonquins (Elliot), a’teba’kwe by the Abenaki of the Ken- nebec (Rasle), mushaquissedes by the Pequods (Pres. Stiles), mal- achxil by the Delawares (Zeisberger), ofindgier on the Roanoke, etc.; and in these few cases, for illustration, we find no common root. The number of varieties that were grown by the Indians are also another indication of antiquity of culture, but this fact of varieties will receive illustration in our quotations from early voy- agers. John Verarzanno, in a letter written in July, 1524, says of the Indians of Norum Bega: “ Their ordinairie foode is of pulse, whereof they have great store, differing in colour and taste from ours, of good and pleasant taste.” Evidently this first visitor to the New England coast had never seen kidney-beans previously.’ In 1605 Champlain, writing of the Indians of the Kennebec -region says: “ With this corn they put in each hill three or four Brazilian beans (Febues du Bresil), which are of different colors. _ When they grow up they interlace with the corn which reaches * Bot. Soc. of Edinb., VII, 291. _ *Hakluyt. Divers Voyages to Am., p. 61, 1885.] Kitchen Garden Esculents of American Origin. 449 to the height of from five to six feet; and they keep the ground very free from weeds.” In 1614 Capt. John Smith mentions “beans” among the New England Indians,’ and when the Pil- grims first landed, Nov. 19, 1620, Miles Standish unearthed from a pit not only corn but “a bag of beans.” Wood also mentions “Indian beans” as among the foods of the Massachusetts Indians, 1629-33.° Lescarbot* says that the Indians of Maine, 1608, like those of Virginia and Florida, plant their corn in hills, “and be- tween the kernels of corn they plant beans marked with various colors, which are very delicate: these, because they are not so high as the corn, grow very well among it.” The most com- plete enumeration of varieties are, however, given in Josselyn, before 1670: “French beans: or rather, American beans. The herbalists call them kidney-beans from their shape and effects: for they strengthen the kidneys. They are variegated much,— some being bigger, a great deal, than others ; some white, black, red, yellow, blue, spotted: besides your Bonivis and Calavances, and the kidney-bean that is proper to Roanoke. But these are ‘brought into the country ; the others are natural to the climate.”® In 1535 Cartier, at the mouth of the St. Lawrence, found “beans of every color, yet differing from ours.” In 1609 Hudson, exploring the river which now bears his name, found within the limits of what is now Rensselzr county, N. Y., “beans of the last year’s growth.” In 1653 Van der Donck, in his Description of the Netherlands, says: “ Before the arrival of - the Netherlanders [1614] the Indians raised beans of various kinds and colors, but generally too coarse to be eaten green, or to be pickled, except the blue sort, which are abundant.’* In 1633, De Vries “proceeded in the yacht up the [Delaware] river, to procure beans from the Indians.”? “Beans” were seen by Newport, in 1607, in ascending the James river? but Heriot, in 1586, describes the okindgier of Vir- 1Champlain’s Voy.

[ May, ginia, “ called by us beans, because in greatness and partly in shape they are like to the beans in England, saving that they are flatter, of more divers colours, and some pied. The leaf also of the stem is much different”! In 1700-8 Lawson? says: “ The kidney-beans were here before the English came, being very plen- tiful in Indian corn-fields. The ‘bushel bean,’ a spontaneous growth, very flat, white and mottled with a purple figure, was trained on poles, [This is undoubtedly the lima, as it answers to the description given to me by a very credible person who se- cured for me samples from a spontaneous plant in Florida, ‘the trunk as large as a man’s thigh, and the plant known for the past twenty-five years, some years yielding as much as fifty bushels of pods,’ and the seeds smaller than the cultivated lima, very flat, white and mottled with purple.} Indian rounceval or mirac- ulous pulse, so called from their large pods and great increase ; they are very good, and so are the bonavis, calavances, nanticokes and abundance of other pulse, too tedious to mention, which we find the Indians possessed of when first we settled in America.” [ Bonavis is perhaps bonavista, a variety of bean sold by Thorburn, a New York seedsman, in 1828. The donxavista bean (Long) of Jamaica, is said to be Lablab vulgaris ; calavances is the Barbadoes name for Dolichos sinensis L., as used by Long, a red bean; and galavangher pea is the Barbadoes name for D. barbadensis Mayc.] In A true declaration of Virginia, London, 1610, p. 12, _ “the two beanes [planted with the corn] runne-upon the stalks of - the wheat, as our garden pease upon stickes.” In 1528 Narvaes found beans in great plenty in Florida and westward, and de Vaca found beans in New Mexico or Sonora in 1535. De Soto, 1539, also found beans in abun- dance,‘ and mentions that “the granaries were full of maes and “small beans,” but we have no clue to the species. Beans are also mentioned in Ribault’s voyage, in 1562, as cultivated by the Florida Indians, The mentions of beans in Mexico are frequent.

The native Mexican name was ayacotle, according to Humboldt, and Ban- croft says that they were the “eg” of the Aztecs, when boiled in the pod exot/, In November, 1492, Columbus, in Cuba, found “a sort of beans,” or “ fields planted with faxones and habas very different from those of Spain,’ and red and white beans were afterwards seen by him in Honduras, according to Pickering. Oviedo says in Nicaraugua many varieties of beans are raised,’ and Gray and Trumbull quote Oviedo as saying that on the island and on the main many bushels are harvested every year, and in the province of Nicaraugua they are indigenous, and a great number of bushels are produced yearly of these and of other Jesoles of other sorts and different colors.* The Indians of Peru, according to de Vega, had three or four kinds of beans called purutu? Squier found lima beans in the mummy covering of a woman from the huaca at Pachacamac, Peru :” and Stevenson also found beans in his exploration of Peruvian tombs which antedated the conquest." Wittmack, who studied the beans brought from Peruvian tombs by Reiss and Strobel, identified the lima beans and also three kidney-beans with P. vulgaris purpurens Martens, P. vulgaris ellipticus precox Alefield, and P. vulgaris ellipticus atrofuscus Alefield.” In Chili Molina says that before the country was conquered by the Spaniards, “thirteen or fourteen kinds of the bean, varying but little from the common European bean, were cultivated by the 1 Bancroft’s Native Races, II, 347. 2 Hist. de las Zud, Seville, 1590. 3 Knox Coll. of Voy., I, 83. 4$ Gray and Trumbull, l. c., 130. 5 F.

In the face of this evidence, which might be even more multi- plied from my notes, it seems unreasonable in De Candolle to doubt the American origin of the common kidney-bean, and his conclusion as shown by his classing “ Haricot Commun Phaseo- lus vulgaris” under “ Especes d’un origine Completement incon- nue ou incertaine” seems to show that with him more evidence is required in the case of American plants than to locate others which are of probably European or Asiatic origin. Bean: Lima.—The lima bean is unquestionably of American origin, and De Candolle assigns its original habitat to Brazil, where the variety macrocarpus Benth., has been found growing wild? Seeds have been found in the mummy graves of Peru, as by Squier at Pachahamac, and by Reiss and Stubel at Ancon.‘ In Southern Florida the lima bean, the seeds, white blotched or speckled with red, is found growing spontaneously in aban- doned Indian plantations,. and various forms are recorded by ` authors under specific names as found in America and other countries, as P. bipunctatus Jacq., P, inamoenus L., P. puberulus Kunth., P. sazcharatus Macf., &c.,° P. derasus Sehirarik (Martens), F Pifus. Jacq., etc. In the mentions of beans by voyagers this form is not discriminated from the kidney-bean, and hence we cannot offer precise statement of its occurrence from such author- ities. It is now widely distributed. It has not been found wild in Asia, nor has it any modern Indian or Sanscrit name (De Can- dolle); Ainslie says it was brought to India from the Mauritius, and is the vellore or duffin bean of the southern provinces. Wight says it is much cultivated, is seldom if ever found in a wild state, and the large podded sort is said to have been brought by Dr. Duffin from the Mauritius.” It is not mentioned by the early 1 Hist. of Chili, 1, 91. ?

A dark red form came to Martens from Batavia, and an orange-red from farther India” Schweinfurth found it in Cen- tral Africa,> Martens‘ received it from Sierra Leone, the form bipunctatus came from the Cape of Good Hope to ‘Vienna, and Martens received it from Reunion under the name Pots du Cap. As Jaquin wrote in 1770 this fixes its appearance in Austria, but it only first reached England in 1779 The form zxamanus was considered by Linnzus to belong to Africa, but he advances, as De Candolle remarks, no evidence of this habitat, and we may remark that the slave trade may well be responsible for the trans- mission very quietly of South American species of food plants of convenient characters for ship use to the African coast. P. der- asus Schrank, considered by Sprengel a variety of P. inamænus, was found at Rio Janeiro. The lima bean is the scimetar podded kidney-bean and sugar bean of Barbadoes ;* it was mentioned in Jamaica by Lunan ;’- it may have been “the bushel bean,” “ very flat, white and mottled with a purple figure,” of the Carolinas in 1700-8,” as this descrip- tion applies very closely to the lima beans now spontaneous in Florida. Two varieties, the “ Carolina” or sieva and the “ lima,’ were grown in American gardens in 1806. Eight varieties, some scarcely differing, are now offered for sale by our seedsmen: Vil- morin enumerates four for France; the speckled form occurs in Brazil™ and in Florida; a black form (P. derasus) in Brazil ; the blood red in Texas;” the dark red with light or orange ruddy spots in the Bourbon isles (Jacquin); the black white-streaked in Cochin China (Loureiro); and the large white, small white or sieva, the red, the white striped and speckled with dark red, and the green, in our gardens.

[May, ever found in a pod,! in our most improved varieties five or even six, Beans : Asparagus.—The asparagus bean has its popular char- acter indicated by its other name, yard-long, indicating the ex- treme length of its pods, which often attain a length of two feet. It is the Dolichos sesquipedalis L., and is said to be a native of the West Indies and of tropical America, and I find no mention of other origin accredited to it. It was included in American seed catalogues in 1828,? and was described as a garden plant in America by Fessenden, 1828, and in France by Noisette.* It is said to have been first introduced into England in 1781.5 It may have been the “Indian rouncival, or miraculous pulse, so called from their long pods and great increase: they are very good” of Lawson, 1700-8, found on his journey to Carolina, but the species was not named by Linnzus before 1762, by Reichard before 1772, nor by Jacquin before 1770-6, No varieties are now sold by our seedsmen, nor has any but the original form been described. My notes are very deficient regarding this species. The name of asparagus bean is probably derived from the lack of membrane, and hence tender character of the pods, which are cooked and eaten as a string bean. Bean: Scarlet Runner.— The culture of the scarlet runner, Phaseolus multiflorus Lam., is very modern. In Johnson’s edition of Gerarde, 1630, it is said to have been procured by Tradescant ; in Ray’s time, 1686, it was grown for ornament; Miller, about 1750, was the first to bring it into repute in England as a vegeta- ble” In America it was mentioned by M’Mahon in 18068 as cul- tivated exclusively for ornament; in 1821 it is included by Thor- burn among vegetables,’ in 1828 the scarlet and white Dutch are. both mentioned among garden vegetable seeds,” and in 1828 or before, both varieties with white or scarlet flowers were grown in France under the name Haricot d’Espagne.” 1 Schweinfurth, 1. c. 1885.] Kitchen Garden Esculents of American Origin. 455 The species is classed as American by Unger, and is described in 1635 under the name Phaseolus puniceo flore, by Jac. Cornuti, in his Canadensium Plantarum Historia, and in 1640 by Parkin- son under the name of P. flore coccineo Four forms are described by Martens? under Phaseolus multiflorus Savi., two of these, the black and the white seeded, were cultivated by Titius in 1654 under the name P. indicus flore miniato, semine negro and semine albo, the names indicating a West Indian origin; one, the scarlet runner, was first mentioned by Cornuti, 1635 ; and the fourth, the P. multiflorus bicolor Arrabida, was first described in the flora of _ Rio Janeiro, 1827. It is now grown in gardens in Europe, and is mentioned for India by Firminger.$ But three varieties are known to our seedsmen, the scarlet run- ner, the seeds black mottled with dull lilac; the painted lady, the seeds brown mottled with creamy white; and the white or Dutch with white beans. Cucumber—One species of cucumber, Cucumis anguria L. (C echinatus Moench., C. angurioides Roem., C. sylvestris americanus, _ angurie folio Pluk., &c., C. asininus Piso, according to Naudin) is considered to be of American origin by botanists from Tourne- fort down to our own day, and its habitat is given by Naudin as “An- tilles, Continental Tropical and Sub-tropical America, Brazil, New Granada, South Florida.” De Candolle* seems to think its Amer- ican origin doubtful, and is disposed to refer it to tropical Africa. Naudin, the authority on Cucurbitacez, refers to this species the guarerva ova, or C. asininus of Piso, 1658, found wild in Brazil; Sloane, 1707,° evidently describes this or an allied species in Jamaica; Long, 1774,° speaks of it as growing wild there, and it is mentioned as growing plentifully there by later writers, as Lunan’ and Titford® In Barbadoes it is mentioned by Hughes, 1750, under the name “ wild cucumber vine.” “ Cucumbers” are mentioned by a few of the early writers on American affairs. They were among the plants grown by the 1 Miller’s Dict. : 2 Die Gartenbohnen. 3 Gard. in India, 151. Origin of Cult. Plants, 267, 441. 5 Nat. Hist, of Jam., 1, 227. ê Jam., 801. : 8 Hort. Bot.

De Soto, however, found “ Cucumbers better than those of Spain” in his inva- sion of Florida, 1539;? Cartier found “very great cucum- bers ” cultivated by the Indians at Montreal, 1535, the epithet very great indicating the European cucumber however. Per- haps the cucuméers cultivated by the Florida Indians, as men- tioned by Ribault, 1562,3 and those seen by Captains Amidas and Barlow in Virginia, 1584, but not those seen in Virginia in 1609,” were this species. “Cowcombers” were also planted on the Ber- mudas in 1609. The “ Concombre’arada” is largely cultivated in some of the West Indies, and under the name “ West India gherkin” appears in the catalogues of our seedsmen. It seems to have been intro- duced into French garden culture by Vilmorin in 1858, but it is mentioned as grown in France by Noisette in 1829; it was culti- vated in England by Miller in 1753, but probably only as a botanical curiosity, It was in American gardens, as a pickle plant, prior to 18287 The lack of its mention by early writers, and the circumstance of its being reported as wild only in the track of the slave trade, would throw doubts upon its American origin; on the other hand we seem to have fewer specific reasons for assigning its origin to Africa or elsewhere. For the present then it must be considered as an American plant. Garlic, Leek, Onion, Chives—Neither the leek, garlic or onion are American plants. It is curious, therefore, to observe that Cortes, on the authority of Humboldt’ cites onions, leeks and garlic among the edibles found on the march to Tenochtitlan. “ Onyons” and “ garlicke ” are also mentioned by Peter Martyr,’ and also “ Cibaioes and macoanes, like unto onions” in the West Indies.” The “ wild leekes ” formerly eaten by the New England 1 Irving’s Columbus, New York, 1859, 1, 380. 2 Portuguese rarity 44, 46. 3 Hak.

This species also furnishes food to the Indians of the Northwest? and with A. cernuum formed almost the entire source of food for Marquette and his party on their journey in 1674 from Green bay to Chicago (to use modern geographical locations). This species does not, however, extend to Mexico, and we do not find mention of species native to the West Indies which would explain P. Martyr’s or Cortes’ mention, although A. gracile Ait., the Jamaica garlic, might answer for one, for these old warriors were not very choice in their applica- tion of well-known names to newly discovered plants, if there was any apparent resemblance. We may only suppose that the introduction of these vegetables from the West Indies, where brought by the Europeans, to Mexico, may have preceded the appearance of the Spaniard. The chives (Aium schenoprasum) occurs in America about Lake Huron, and is also wild in Temperate and Northern Eu- rope, Siberia and Kamschatka.’ (Tobe continued.) . 10: THE LEMUROIDEA AND THE INSECTIVORA OF THE EOCENE PERIOD OF NORTH AMERICA. BY E. D. COPE. WO distinct divisions are included in this article, because the material is not yet sufficiently complete to enable me to refer certain forms to the one rather than the other. The only charac- ters on which the osteologist can rely in endeavoring to distin- guish the two groups are these: First, the terminal phalanges of the Insectivora are compressed and curved, forming claws; while those of the Lemuroidea and of most other Primates are more or less flat, and at the extremity rounded and depressed,* or more or less like hoofsë Second, the hallux or inner toe of the posterior foot is opposable to the others, a character dependent on the form of the entocuneiform bone of the tarsus, which has in that 1 Josselyn’s Rarities, 84. 2R.

In the Insectivora this structure is wanting, the inner toe being fixed in a position parallel with the others as in the Carnivora. In the Lemuroidea the position of the thumb or pollex is less different from what is seen in the Insectivora, than is the case with the posterior foot. In the true lemur the thumb is but little opposable, except in the genus Chirogaleus and some others. The distal end of the tra- pezium bone of the carpus with which the thumb articulates, does not form a part of acylinder in the Lemur or in the Tarsius. When the thumb becomes opposable in the monkey proper, the — thumb facet of the trapezium is not rounded, but is wide and a little concave. It is not till we reach the man-like opposable thumb of the anthropoid apes that we find this bone presenting to the thumb a semicylindrical face like that of the entocunei- form bone of the posterior foot. The Condylarthra as I have pointed out must be regarded as a division of the order of Taxeopoda, along with the Hyracoidea, the lemurs, the monkeys and man. The difference between the hoofs of Phenacodus and the ungues of Lemur is too slight to admit of wider separation: and the other parts of the structure show an equal agreement. There is no trace of opposability of the hallux in Phenacodus however, nor any os centrale of the car- pus, characters which show that the suborder Condylarthra and - Lemuroidea are distinct. In the pollex or thumb of Phenacodus, however, there is a distinct indication of opposability, though it is not so well developed as in the genus Lemur. The basal artic- _ulation with the trapezium is narrow, but is directed partly fore and aft, so that the thumb looks inwards. Its power of flexure at the base has been slight, but the flexure at the base of the first phalange has been such as to make the end of the thumb quite opposable? From the Condylarthra then we trace the order Quadrumana on the one hand, and the hoofed orders on the other. _ In the following pages I will not attempt to distinguish which of the genera are lemuroid and which are insectivorous, since the phalanges are yet unknown. An exception must be made in ‘the case of the genus Pelycodus, where a single compressed | -P NATURALIST, April, 1885.

This alone does not decide the question, since such a claw exists on the second toe of many Lemuroidea. These animals are readily distinguished into three divisions or families by the number of their premolar teeth. There are four such teeth in the Adapide; three in the Mixodectide, and two in the Anaptomorphide. In the Adapidze we have the most primitive type, and the one most nearly allied to the Condylar- thra, from which they were probably derived. In the Mixodec- tide we have the dental formula of the existing lemurs, with a tendency in some of the genera to develop large cutting teeth in the position of incisors, thus approaching the aye-aye. In the Anaptomorphide, on the other hand, we find a dental for- mula like that of the Simioidea and Anthropoidea, or higher E ZZ ` FIG. 1.—Adapis parisiensis Cuv., skull nat size, from the Phosphorites of Central France. From Filhol. monkeys and apes; and in them we seem to geta hint of the derivation of these higher forms, and of man himself. The genera of the Adapidz are distinguished by various den- tal characters. Such are the presence of a second anterior-inner cusp of the inferior true molars; the presence of an internal cusp of the fourth inferior premolar; the number of incisor teeth, and number of single-rooted premolars. The difference between the quadrituberculate and the quinquetuberculate inferior molar may be understood by reference to Fig. 2, where the teeth of the gen- era Hyopsodus (a) and Microsyops (2), which represent the two , are placed side by side. : oe (Notharctus, Tomitherium, Figs. 4-5) the fifth cusp is present but weak.

The same bone resembles also that of many marsupials, but the flat ilium, elevated position of dental for- amen, and absence of inflection of the angle of the lower jaw, etc., render affinity with that group highly improbable. a tt a Fic. 6.—Tomitherium rostratum Cope, fore leg of animal represented in Figs. 5-7, nat size.

The length of the femur indicates that the knee was entirely free from the body as in the Quadrumana, constituting a marked distinction from anything known in the Carnivora, in- _ cluding Nasua. The round head of the radius indicates a com- plete power of supination of the fore foot, and is different in form from that of Carnivora, including Nasua; and, finally, the distal 1885.] Eocene Period of North America. 463 end of the radius is: still more different from that of Nasua,and resembles close- ly that of monkeys of the genus Semnopithecus. We have, then, an ani- mal with a long thigh free from the body, a manus capable of complete pro- nation and supination, and details of lower jaw an teeth quite similar to those of the lower monkeys. The form of the humerus and its relative length to the femur are quite as marked as in some of the lemurs. The most marked differ- ence is seen in the increased number of teeth; but in this point it relates itself to the other Quadrumana, as the most ancient types oO Carnivora and Ungulates do to the more modern, This genus is allied to Adapis Cuvier, of the French Eocene (Fig. 8), but differs in the posses- sion of but two incisors on each side; in Adapis there are three, according to Fil- hol. From that genus and Opisthotomus, it differs in the structure of the last inferior molar, as exhibited in the analytical ie There are several species of Tomitherium, but the Fic. 7.— — Tomitherium KAE ope, part animal figured in Figs. a, ilium inner si posterior ig. ide; å, femur path Se do. 464 The Lemuroidea and the Insectivora of the [May, best known is the T. rostratum from the Bridger formation of Wyoming. The following points may be gained by comparison with the skeleton of Lemur collaris (catalogue Verreaux). There is con- siderable resemblance in the details of structure of the molars from the third to the sixth, inclusive. Of course the anterior teeth differ widely in the two, and the last true molar of the Lemur has no heel. The principal difference in the humeri is seen in the superior size of the epicondyles of the T. rostratum, and the rather more robust character of the shaft. The proximal half of the ulna is deeper, and the olecranon is not so wide in 7. rostratum. The proximal part of the radius is very similar in the two species, but the distal extremity is in the 7. res- tratum less transversely extended, and thicker anteroposte- riorly. There is also much similarity in the ilia. The crest is more extensive in T. rostratum, and the inferior border is thinner at its proximal part. Towards the acetabulum the increase in width of this border is similar, and the anterior inferior spine is as prominent. The resemblance between the femora amounts to identity of character; that of the T. rostratum is more robust. The Mixodectide include four and perhaps five genera.

It is represented by a cranium in excellent preserva- _ tion (Fig. 8) which has been fully investigated by Filhol. This . able Se regards it as most nearly allied to the genus = now existing in Africa.

There are two species from the Puerco beds, The smaller of these, M. pungens Cope (Fig. 9), is about the size of the kit fox. Its premolars are of irregular size. In the two other genera the fourth premolar has a second cusp on the interior side of the principal one. Both have the crowns of the inferior true molars composed of two triangles as in Mixodectes and Pelycodus. In Microsyops Leidy, there is but one one- rooted premolar. There are three spe- yc.

Among Lemuridz its dental formula agrees only with the Indri- sinz, which have, like Anaptomorphus, two premolars in each jaw. But no known Lemuridz possess interior lobes and cusps of all the premolars, so that in this respect, as in the number of its teeth, this genus resembles the higher monkeys, the Simiidz and Hominide more than any existing member of the family. Of these two groups the resemblance is to the Hominide in the small size of the canine teeth. It has, however, a number of resemblances to Tarsius, which is perhaps its nearest ally among the lemurs, although that genus has three premolars. One of these points is the anterior extension of the otic bulla, which is extensively overrun by the external pterygoid ala. A conse- quence of this arrangement is the external position of the fora- men ovale, just as is seen in Tarsius. Another point is the prob- ably inferior position of the foramen ovale. Though this part is broken away in the cranium of Anaptomorphus homunculus, the paroccipital process is preserved, and has the position seen in Tarsius, as distinguished from the Indrisine, Lemuride, Gala- ginz, etc. In this it also resembles the true Quadrumana. When we remember that the lower Quadrumana, the Hapalidz and the Cebide, have three premolar teeth, the resemblance of Anaptomorphus to the higher members of that order is more evident. The brain and its hemispheres are not at all smaller than those of the Tarsius, or of the typical lemurs of the present period. This is important in view of the very small brains of the flesh-eating and ungulate Mammalia of the Eocene period so far as yet known. In conclusion, there is no doubt but that the genus Anaptomorphus is the most simian lemur yet discovered, and probably represents the family from which the anthropoid monkeys and men were derived. Its discovery is an important addition to our knowledge of the phylogeny of man. The Anaptomorphus homunculus was nocturnal in its habits, and its food was probably like that of the smaller lemurs of Madagascar and the Malaysian islands. Its large orbits and large otic bullae indicate great acuteness of the senses of sight and hearing. Its size is a little less than that of the Tarsus spectrum. In Pelycodus we have a more decidedly insectivorous type of dentition in the lower jaw, although that of the upper jaw (Fig. 1) has a lemurine character.

A mutual reserve subsisted between them and the Esquimaux, and the latter fled in the greatest trepidation when they discovered any traces of them in their neighborhood. In 1790, however, much of this coldness was removed, when several families of these Indians came to Kippokak, an European factory about twenty miles distant from Hopedale. In April, 1799, the missionaries conversed with two of them, a father and son, who came to Hopedale to buy tobacco. It appeared that they were attached to the service of some Cana- dians in the southern settlements, as well as many others of their tribe, and had been baptized by the French priests. They evi- dently regarded the Esquimaux with alarm, though they endeav- ored to conceal their suspicions, excusing themselves from lodg- ing in their tent on account of their uncleanly habits. At parting they assured the brethren that they would receive frequent visits from their countrymen, but this has not as yet been the case.” From Cartwright’s “ Journal of a Residence in Labrador” we glean the following statements, which certainly confirm those of the Moravians: In 1765 a blockhouse was erected in a small fort at Chateau bay to protect the English merchants from the Eskimo. (Cartwright also gives'the best account we have seen of the Bethuks of Newfoundland.) The southern tribe of Eskimo were at Cha- teau bay in 1770, Cartwright observing that some Moravians were there at the same time. He also states that there was an Eskimo settlement “some distance to-the northward” of Cape Charles, and that a family of nine Eskimo came to spend the winter living near Cartwright’s house, and more Eskimo came to join them in July, 1771, there being thirty-two in all; they traded whalebone with the Eskimo to the northward. Cartwright saw deserted Eskimo winter houses near Denbigh island. In 1771 he saw an Eskimo pursuing a “ penguin” in his kayak near Fogo island, off the coast of Newfoundland! August 30, 1772, “500 or thereabouts ” Eskimo arrived at Charles’ harbor from Chateau bay to the southward, to meet their relations from London, whom Cartwright had the year previous taken with him to London, some of them having died in Eng- land of the small-pox. In April and May, 1776, Eskimo were observed living near Huntington island. Many Eskimo died in Ivuktoke inlet, probably from the small-pox, brought over from . 480 Notes on the Labrador Eskimo [May, England. Cartwright also reports seeing Eskimo at Huntington island in 1783, also at Chateau bay, where they were observed in 1786. The foregoing extracts abundantly prove that the Eskimo _ repeatedly crossed to Newfoundland, residing, during the summer at least, on the outer islands opposite Belle Isle. No reference is made to the former presence of the Eskimo in Newfoundland. It is not improbable that there was at least a slight intercourse, be- tween the Bethuks, the aborigines of Newfoundiand, said to be a branch of the Algonkins, and found to be in possession of the island by Cabot in 1497. A stone vessel dug up with other Bethuk remains, is “an oblong vessel of soft magnesian stone, hollowed to the depth of two inches, the lower edges forming a square of three and a half inches in the sides. In one corner is a hollow groove, which apparently served as a spout.”! If this is, as has been suggested to us by Professor Tylor, attributable to the influence of Eskimo art, the style may have been suggested by the possible intercourse of these aborigines with the wandering imo. In connection with the subject of the relations between the In- dians of Newfoundland and the Labrador Eskimo, may be cited the following statement of that industrious historian, the late Jesuit, Father Vetromile. In an article entitled “ Acadia and its Aborigines,” he says: “ The Etchimins, Micmacs and Abenakis are very often considered as one nation, not only on account of the similarity of their language, customs, suavity of manners and attachment to the French, but also for their league in defending themselves against the English. Although the Micmacs are generally somewhat smaller in size than the other Indians of Acadia and New France, yet they are equally brave. They have made a long war against the Esquimaux (eaters of raw flesh), whom they have followed and attacked in their caverns and rocks of Labrador. Newfoundland must have several times been the field of hard wars between the Micmacs and Esquimaux; the latter were always chased by the former” (p. 339). Whether these statements are well grounded, we cannot say, : ean its history, its present condition, and its prospects in the future. Joseph Hatton and the Rev. M. Harvey, Boston, 1883, p. 169.

Nearly all the extracts we have made tends to show that the Eskimo were generally driven northward by the Indians and confined by them to their natural habitat, the treeless regions of Arctic America, whither the In- dians themselves did not care to penetrate. In 1811 two Moravian missionaries! explored the northern coast of Labrador from Okkak to Ungava bay, making an excel- lent map of this part of the coast. The expedition arose from their desire to establish missions where the Eskimo were abun- dant, as farther down the coast they were regarded as “ mere stragglers.” An Eskimo tradition of interest is mentioned in this book, as follows: “July 24th. Amitok lies N. W. from Kummaktorvik, is of an oblong shape, and stretches out pretty far towards the sea. The hills are of moderate height, the land is in many places flat, but in general destitute of grass. On the other side are some ruins of Greenland [Eskimo] houses. “The Esquimaux have a tradition that the Greenlanders [2. e., Greenland Eskimo] came originally from Canada, and settled on the outermost islands of this coast, but never penetrated into the country before they were driven eastward to Greenland. This report gains some credit from the state in which the above-men- tioned ruins are found. They consist in remains of walls anda grave, with a low stone enclosure round the tomb, covered with a slab of the same material. They have been discovered on islands near Nain, and though sparingly, all along the whole . eastern coast, but we saw none in Ungava bay.” (To be continued.) 1 Journal of a voyage from Okkak, on the coast of Labrador, to Ungava bay, westward of Cape Chudleigh, undertaken to explore the coast and visit the Esqui- maux in that unknown region.

PACKARD AND E. D. COPE. Naturalists will be the gainers by the present discussion of the question as to the existence of objects of more or less than three dimensions. We are accustomed to regard mathe- matics as exact, and in its true function as the science of relations it is so. But we have not always remembered that it may treat of the relations of imaginary quantities as readily as those of real ones. Hence it need not surprise us if the mathematical mind sometimes concerns itself but little with the question of the reality of the subjects of its discussions, This is the explanation of the ex- traordinary mental phenomenon displayed at the present time in the attempt, by some men of much acuteness, to persuade them- selves and others of the existence of objects of two and four dimen- sions. The argument rests on the very transparent assumption ` that because we usually see only the surface of things, z. €., two dimensions, such surface has an existence apart from the three- dimensional body of which it is an aspect. The deduction then follows that if from the perception of two dimensions we can rise by mental process to a perception of three dimensions, why is it not possible that some minds can rise from the third dimension to a perception of a fourth. The naturalist, however, will expect a third dimension before he will permit himself to believe that he has an object, and any one who would do otherwise would soon find himself in the limbo of the damnati. We invite our two and four-dimensional friends to give us a systema nature. Let them have their Linnzeus, Cuvier and Darwin. We fear, however, that two-dimensional objects placed edgwise to the line of vision would be overlooked by these gentlemen, while for four-dimen- sional beings a new teratology would have to be written. Professor John Collett has been removed from the posi- tion of State geologist of Indiana, and Professor J. Maurice Thompson has been appointed in his place by the legislature of Indiana. This change is from purely political motives, as noth- ing was alleged against Professor Collett unfavorable to his administration. We regret this change without knowing aught against the new appointee, as we regret all changes in scientific official relations without due cause.

The bestiarians are getting into trouble through their misrepresentations and libels. We learn from the Journal of Science that one Ernst Weber, in Germany, has been imprisoned for six months for making false assertions respecting the physio- logical investigations of Dr. Pelz. Professor H. N. Martin, of Johns Hopkins University of Baltimore, publishes a vigorous contradiction of the assertions of some British bestiarians, and protests against their statements as libelous. In Philadelphia Dr. Wister, addressing the Women’s Society for the suppression of Physiology, calls vivisection “a crime.” On the other hand Dr. W. W. Keen made vivisection the subject of his valedictory be- fore the graduating class of the Women’s Medical College. He demonstrated the importance of this branch of physiological research.

D. Lacoe, of Pittston, Pa., “ who has directed for years explorations, still continued, in the more interesting localities of the coal-fields of North America. He has thus brought up, at great expense, a collection of fossil plants of divers formations, of insects, crustaceans, etc., which is not only by far the largest and most valuable of any in America, but which certainly may compare in this specialty with the rich- est collections of any of the European museums,” The other report is marked P.P.P., 1884, and contains two palzontological papers, valuable in themselves and for their illus- trations. The first one, by Mr. C. E. Beecher on the Ceratiocar- idæ of the Upper Devonian measures, we have already noticed in this journal; the second is a note by Professor James Hall on the Eurypteride from the lower coal measures, and it is illus- trated by six heliotypes, an excellent way of illustrating these fossils. One new species (Eurypterus potens) is described, and the remains of other species fully illustrated. THE ZOÖLOGICAL RECORD FoR 1883.\—That the work in sys- tematic zodlogy throughout the scientific world went on in 1883 much as in former years, is proved by the fact that the size of each of these useful records remains about the same from year to year. The present volume, which contains no references to the Arachnida, is only twenty-eight pages shorter than its predeces- sor, in which that class occupied thirty-three pages. : he year 1883 was, so far as regards the mammals, chiefly marked by the large number of paleontological books and papers which appeared, among which those of Ameghino, Cope, Filhol, and Lydekker are the most prominent. While there are no striking novelties in ornithological work, the year is reported to have been remarkable for a large amount _of steady work. Little appears to have been done with the rep- _ tiles and Amphibia; beyond special papers no works on ichthology of general importance appeared this year. ` As usual over half the volume is devoted to the Crustacea and especially the insects. Regarding the former several monographs Ae 1 The Zoblogical Record for 1883 ; being volume twentieth of the record of zodlog- ` cal literature. Edited by E. C.

Important papers on the myriopods appeared in 1883, and of entomologi- cal literature there appeared important anatomical and morpho- logical as well as palzontological works and papers, besides some faunal works of value. We shall in another place draw attention to recent discoveries which have not been quoted in our entomo- logical notes. It is enough to take one’s breath away to be told that the number of new genera described in 1883 was 1079, while the Arachnida have yet to be heard from. As we have said in former years the Zodlogical Record is of immediate and pressing value to American students, and it is sur- prising that more copies are not taken by our working natu ralists. MILLSPAUGH’S AMERICAN MEDICINAL Piants.'—This is a prom- ising work now issuing in parts, each containing six colored lithographic plates, and from ten to fifteen pages of descriptive text. Upon each plate are shown the characteristic portions of some plant with dissections of the floral organs, or the fruits and seeds. The drawings are generally accurate and the coloring is good. Of course one need not look in a work like this for that degree of accuracy and finish which we are accustomed to see in the drawings by Isaac Sprague, but still they answer their pur- pose admirably, of enabling the student to identify the different medicinal plants of his flora. ; aii Five parts (composing Fascicle 1) of this publication have al- ready appeared, including thirty plates. The whole work will contain 180 plates, and it is the intention of the publishers to- complete it within two years. The low price at which it is offered (five dollars per fascicle) places it within reach of everyone who is interested in the medicinal plants of the country. It will also be found an interesting and valuable addition to the library of the botanist.— Charles E. Bessey.

Rabba the capital of Nupé, „has 70,000 inhabitants. Above Egga the river becomes shallow, and vessels drawing more than four or five feet cannot proceed to Rabba. The constant falling in of the western bank renders navi- gation of the Lower Nile difficult. French commercial companies no longer exist on the Lower Niger. The Upper Niger is domi- nated by three powerful chiefs. The “prophet” Samory, a sort of religiously fanatic slave-hunter, who burns his unmerchantable prisoners, occupies the upper portion. Below him is Amradon, chief of a better organized state, with an army of Tonconleur cavalry and Bambarra infantry, and lastly, between Sansandig and Timbuctoo, comes Tidiani, who, with his bands of brigands, cuts off the communications of the latter once flourishing city. Timbuctoo has for over 200 years been ruled by a “ kahia,” a kind of burgomaster originally appointed by the Emperor of Morocco from the Moorish Andalusian family of Er-Rami. The office became hereditary, but the present kahia or Amir Muham- med Er-Rami, who is now in Paris, has little power, and is prac- tically a puppet in the hands of whichever of the rival Arab, rber or Fulah factions have the upper hand. The Arab chief, Sheikh Abadin, sides with the Fulahs or Fulani, whose power is continually increasing, and who are likely to become absolute masters of Timbuctoo unless it falls into the hands of some Euro- pean power. Harrar.—The province of Harrar proper lies in a circle around - the city of that name, and has a population, according to Major F. M. Hunter, of nearly 329,000. The city of Harrar is fortified so as to be fairly defensible against native attack, and contains an area of 200 acres, and a population of about 30,000, two-thirds of whom are women, and only about one-third natives of the city. The suburbs contain 6000 more. Harrar is regarded by Professor Keane as an outlier of Abyssinian civilization, and perhaps is a remnant of the ancient kingdom of Adela or Ada, once a power- ful enemy of Abyssinia. At any rate it has for centuries preserved within its walls a distinct race, speaking a tongue not understood by its neighbors, and has been the center of trade for the sur- rounding countries, dispatching caravans to Tajura, Zeila, and Berbera. The city has some 4500 domiciles. Major Hunter gives some details of the material condition, dress, domestic ceremonies, etc., of the women, and refers to the account given by Burton in “ First Footsteps in East Africa.” Debased Egyptian piastres and Maria Theresa dollars are the only currency, and the only indus- . tries are bookbinding and weaving. The principal indigenous ex- o> ‘ports are coffee,and wars or safflower.

This lake is forty-five miles long and twelve wide, and has numerous small islands covered with the nests of sparrows. The state of Sam-Sam, composed of mestizos, or half-caste Malays and Siamese, a popu- lation somewhat inclined to piracy, exists at about 7° 14’ N. lat. ——Mr. Mueller’s reconnaissance survey between Cascade plateau and Lake McKerrow, on the west coast of the middle island, New Zealand, has shown that a great part of the Hope range is auriferous, while traces of gold occur along the whole length of Gorge river. The most remarkable geological feature is the Olivine range, a red-violet mass devoid of almost every trace of vegetation from about 1000 feet above the Cascade river. Evurope.—Luropean Notes—The Norwegians have discovered several new islands to the east of King Karl or Wiche land. In 1884 the west side of Spitzbergen was blocked by a belt of land- ice, the whole summer through, while the east side, which is usually blocked, was more open than for many years. The prevail- ing direction of the winds appear to cause these changes. Observa- tions prove that the level of the shores of the Baltic is changing with considerable rapidity, the northern shore rising, while the south- ern is sinking. The northern part of Sweden has risen seven feet in the last 134 years, but the rise diminishes southward until at the Naze it is only one foot, and at the island of Bornholm nothing. The line of equilibrium passes along the islands of Bornhohm and Gothland. The Brussels National Institute ot Geography is now publishing a fac-simile reproduction of the plans of a hundred Belgian towns drawn up between 1550 and 1565, by J. de Deventer, at the command of Charles V and Philip II, of Spain. The originals are divided between the libraries at Brussels and Madrid. America.—Physical Aspect of Brazil—The greater part of Brazil is an elevated plateau, having a main elevation of from one to more than three thousand feet. This great plateau is bounded northward by the great Amazonian depression, westward by basin of the Paraguay, which is continued northward by that of the Guaporé, a tributary of the Madeira, and all along the ocean border by a narrow strip of coast. North of the great Amazonian valley rises a second smaller pleateau, continuous with that of 490 General Notes. [May, Guiana. The sketch map of Brazil, prepared by O. A. Derby for Vol. 1 of La Geographica physica do Brazil is a revelation to those whose knowledge of Brazil is mainly confined to the Amazons. Not one-tenth of the entire country, according to this map, is less than 300 meters above the sea, and the region above 1000 meters is at least half as large as those below 300. The true mountains of upheaved strata are mainly in the eastern and central portions of the Brazilian plateau, and may be considered as forming two groups, separated by the elevated table lands of the Parana and Sao Francisco basins.

R. C. Selwyn, Director of the Geological Survey of Canada, states his belief that Lake Mistassini consists of several almost separate lakes, but that the entire body of water is not to be compared with that of Lake Superior. The exploration of the region was commenced in 1870-71, and last spring a party was despatched to continue the work. The sensational article in the Montreal Witness arose out of an interview of a reporter with Mr. F. H. Bignell, who ha just returned from taking winter supplies to the exploring party. The communication of Mr. Selwyn is accompanied by a tracing of Eugene Tache’s map of the province of Quebec, the only map upon which the results of the surveys of 1870-71 are correctly laid down. Geologically the lake lies in a basin of flat lying lime- stones, probably of Lower Cambrian age, resting on Laurentian and Huronian rocks. Dr. Carver. A Correction.—In your March number, p. 231, an error crops out in “ Carver the celebrated English traveler.” — According to the North American Cyclopedia, “he was an American traveler, born at Stillwater, Connecticut, in 1732, The notice proceeds with an incorrect statement, viz., “ He crossed the continent to the Pacific, and returned to Boston in 1768, having traveled about 7000 miles Whereas, with a plan to go to the Pacific, he left Boston in June, 1766, went by the lakes, Green bay and Fox river portage to and up the Mississippi and the sources of St. Peter’s river, where - he wintered.

Tue MamMatiAn Genus Hemicanus.—This genus was charac- terized by me in the NATURALIST for 1882, p. 831,' from a num- ber of teeth. The typical species, H. vultuosus was supposed to be a beast of about the sizeof atapir. Its exact position was not determined. Jaws with teeth and a part of the skeleton of a second and smaller species of the genus recently received, throw much light on its characters, and demonstrate that it is one of the most remarkable of the Eocene Mammalia yet discovered. e claws are large and compressed like those of a prehensile- footed carnivore. The astragalo-tibal articulation is nearly flat. The femur is very robust, and has a low third trochanter, as in Bunotheria generally. The vertebræ of the neck are short an wide. The jaws have a very large and wide coronoid process, as in Calamodon, and the horizontal rami are very robust. The molar teeth of the lower jaw have but one root.. Only one true moiar (the first) is preserved, and it has the crown worn. [Its outline is sub-round, with a notch on the internal side, There are proba- bly four premolars, and their crowns are short, obtuse cones, ' with a low heel-like expansion at the inner side of the posterior base. They resemble very nearly the teeth of some of the eared seals. There is a robust canine tooth in the upper jaw, which is not separated from the premolars by a diastema. There is at least one superior incisor, but the exact number is unknown. There is a large tooth on each side of the symphysis of the lower jaw, but in the specimens it is not in place. It has enamel on the anterior face only, and its apex is worn transversely. The wear descend- ing passes to one side of the middle line. It evidently has a median position, and may therefore be an incisor. Its form reminds one of that of the second inferior incisor of Calamodon, but the enamel-face is much shorter. Should the large inferior teeth be canines, the mandibular den- tition will greatly resemble that of the seals, as does that of the maxillary bone. The absence of postorbital angles resembles the condition in the Phocide.

MARSUPIALS FROM THE Lower Eocene oF New Mexico.—Two families undoubtedly referable to the Marsupialia have been iden- tified from the Puerco Eocene, the Polymastodontidæ and Plagi- aulacidæ (see NATURALIST, 1884, p. 686, for an account of these animals). One genus of each is known, viz., Polymastodon and ' Ptilodus. I now add a third genus in the Neoplagiaulax of Lemoine, which belongs to the Plagiaulacidæ, and has been rep- resented hitherto by a single species from the Puerco beds of Rheims, France. The American species is very distinct from the European, and comes from the base of the formation in New Mexico. I describe it as follows : .003. D. Baldwin. Ptilodus trovessartianus Cope, Report U.

Polymastodon attenuatus, sp. nov.—This form is represented by a mandibular ramus with entire dentition, of one individual, and by a superior incisor with portions of inferior molars of a second. The specific character is seen in the very compressed incisors and general lightness of structure of the ramus, in which it is quite different from the species of similar size, the P. taoënsis and P., latimolis (NATURALIST, April, 1885). The tubercles and propor- tions of the true molars are as in P. taoénsis, The apex of the fourth premolar is transversely fissured. The superior incisor is much more compressed than in that of P. taoënsis, and is more rapidly acuminate in its form, to the subacute apex. There are no facets of the internal side as in that species. The enamel covers almost the entire external face, and is marked by rather coarse parallel grooves. A groove runs along the concave edge of the crown, forming the edge of the enamel excepting for its distal half, where the enamel crosses it, and covers the internal side for its distal fourth. The inferior incisor is also much compressed so that the enamel is presented externally rather than anteriorly, and its cutting edge is nearly anteroposterior and not transverse, as in P. taoénsis. Its surface is obsoletely grooved.

Tue Lour Fork Miocene IN Mexico.—A considerable extent of tertiary deposit in the State of Hidalgo and the adjoining parts of Vera Cruz has been announced by Professor Antonio de Cas- tillo in the report of the School of Mines of Mexico for 1883. I recently visited the region, and obtained from the beds bones and teeth belonging to species of Protohippus, Hippotherium and Mastodon, and probably Procamelus; and Professor Castillo has teeth of Dicotyles. It is thus evident that the horizon is the Loup Fork or Upper Miocene of the North American series. This is by far the most southern exhibition of this formation, the nearest locality which I have identified with it being in New Mexico. In its Mexican area it occupies a tract of at least eighteen miles by _ six, which at present presents an extremely irregular surface. It i is excavated into numerous valleys of erosion by tributaries of the Tuxpan and Benados rivers, some of which are fifteen hun- dred feet in depth and quite narrow. The axes of the high tands consist of trap, which in some instances are dykes, as the lime- stones of palæozoic or mesozoic age lie against them inclined at high angles. Some of these traps inclose masses of obsidian of various sizes. _ tire Loup Fork formation is now not less us si le en _ than two thousand feet in thickness, as it not only fills the valleys but also caps the traps. Several thin beds of coal occur in it, both above and below the escarpments of trap; in the latter case $% 1885.] Geology and Paleontology. 495 frequently dipping at a low angle towards the trap. Between the coal beds are shales apparently composed of volcanic ash, and beds of excellent clay.

D. Cope. Discovery oF AN EXTINCT ELK IN THE QUATERNARY OF NEw Jersey —Professor William B. Scott, of Princeton, made (reports Science) a communication on an extinct elk, a skeleton of which was recently found in the quaternary of New Jersey. The bones, which are ina state of remarkable preservation, were dug from a bog near Mount Hermon. ey were at first supposed to belong to a moose, but, on further examination, it was seen that the skeleton was that of a remarkable form of deer-like animal, between the genera Cervus and Alces, and the name Cervalces — the velvet, indicating that the individual probably died in Sep- tember. They are provided with curious scoop-shaped processes at the base, which, when the head was lowered, must have actually obscured lateral vision. The use of these processes, the presence diagrams, Tertiary Man at THeNay.—The most interesting question brought before the geological section of the French Association was the existence of man in the tertiary epoch. In 1867 the Abbé Bourgeois found at Thenay (Loir et Cher) some flints which he believed to be worked by man or split by fire. Extensive excava- tions were made at Thenay, which is about twenty kilometers from Blois, and forty members of the Association repaired tł to examine the locality. Comparison with the surrounding strata showed that the bed (of greenish clay mixed with small flints) in which the presumably worked flints occurred, was an upper 490 General Notes. [May, stratum of the argillaceous flint-bed which everywhere underlies the Beauce limestone, and therefore is early miocene or even eocene. Only two flints were found which bore the apparent impress of human handiwork, but the splitting which has been attributed to fire, was more common. The great majority of the members concluded that, considering the enormous extent of the beds, the rarity of the peculiar flints found and their unknown use, and the possibility that the effects, like those of fire, were pro- duced by some unknown natural cause, there was nothing to war- rant a belief in the existence of man at so remote a period. A map of the environs of Blois constructed for the geological map of France, and presented to the Association, shows that the Beauce limestone was deposited in a lake, while the clay, with flints, passes beneath the limestone and forms the borders of the lake. GEOLOGICAL Notres.—General—It appears from Dr. R. D. M. Verbeek’s atlas and description of Sumatra, between 0° 14” and 1° S. lat. and 99° 45’ and 101° 25 E. long., that productive coal is wanting in the explored district, and that mesozoic beds are also lacking. The Eocene lies upon the Carboniferous, and the newer Tertiary strata appear to be wanting in the same area. The conclusions arrived at concerning the geology of the island, are that at the end of the Eocene or beginning of the Miocene, an eruption of andesite from fissures occurred in Sumatra, Java an Borneo, contemporaneous with the uplifting of the highlands of Padang. In Bencoolen, Lower Miocene beds overlie this andesite, and at the same spot Middle and Upper Miocene and Pliocene strata also occur. The Pliocene marl shows no trace of newer eruptive materials, while the overlying Quaternary consists of clay and andesite material. In Java, also, the Eocene strata are broken through by andesites and basalts, and the probably Mio- cene strata which overlie the orbitoides limestone contain andesite materials. The great craters are more modern than the fissure- poured andesite, and between them intervened a period of com- parative calm. The commencement of the activity of these vol- canoes cannot be fixed with certainty, but was probably nearly quite at the end of the Tertiary period. Carboniferous —M. Dieulafait has conducted a series of experi- ments upon recent Equisetacez, with a view to ascertain the rea- son why coal is always impregnated with sulphur, and why coal ashes do not contain free carbonates of the alkalies, such as were general in the ashes of recent plants. He finds that modern Equisetaceze contain a proportion of sulphuric acid very much in excess of that contained by other recent plants, and arrives at the conclusion that, as the flora of the Coal Measures was a largely composed of Equisetacez, it is to them that the great ` _ quantity of sulphur and sulphate of lime is due. The absence of 1885.] Mineralogy and Petrography. 497 alkaline carbonates in the ashes of coal is a natural consequence of the excess of sulphate of lime always present in the ashes.

The petrographical descriptions are, however, largely taken from the work of others, while those which are original are not sufficiently detailed; the generaliza- tions are often broader than the facts thus far accumulated woul seem to warrant; and even the statement of the writer’s most original ideas regarding rock nomenclature and classification is not in certain points altogether free from ambiguity. Chapter first, containing nine sections, deals with the interior structure of the earth; the origin and alterations of rocks and of their constituent minerals ; the methods of rock-classification hitherto followed and their ‘defects, and lastly, the proposal of the author’s system of classification. Sedimentary and eruptive rocks are held never to grade into one another, as sometimes appears to be the case. Each class mainly to the alteration of the older ones. The minerals tend to constantly pass from less stable compounds to those which are more stable for the conditions now existing on the earth. The alteration therefore varies with the age, and also, under the same _ conditions, inversely as the amount of silica which the rocks contain. Foliation or schistose structure is no necessary proof ot ei Deets» Us origin of a rock. Inasmuch as the alteration of ces on in some cases much more rapidly than in others, lithological character can be regarded as no index of age. The mineral constituents of an eruptive rock are divided into three classes: 1st, those present in the magma before its extru- sion (foreign) ; 2d, those formed at the time of the consolidation of the magma (indigenous) 3d, alteration products (secondary). The first class is regarded as composed entirely of foreign inclu- sions, no account .being taken, as it seems, of such minerals as leucite, olivine, etc.,which may crystallize out of the molten magma long before it is extruded or solidifies! Hornblende appears to be regarded as always belonging to either the first or third class The present systems of rock-classification, based on chemical composition, structure, mineral constituents and geological age, are reviewed in turn and pronounced artificial and unsatisfactory. Section viii contains the statement of thirteen principles which the author thinks should underlie a natural classification of rocks. It must be confessed, however, that this attempt is not altogether - Satisfactory. It is stated that a// the petrological (field), oe cal (microscopical) and chemical characters of a rock must be used in ining its species, but in what way is not made clear. Mineral composition is sufficient to define varieties but _ Rot species. All rocks which may be followed from one form to 1885.] Mineralogy and Petrography. 499 another, whatever be the changes of chemical or mineral compo- sition or of structure, within certain limits, form a species; but what these limits are is not stated. A diorite derived by para- morphosis from a gabbro must be called a gabbro, Even quartz which might have replaced a basalt would have to be called basalt, strange as this would seem, unless these “ certain limits ” be defined. Wadsworth's classification seems to be, after all, mainly a chemical one in which the rocks of approximately the same composition, but differing in their constituents, structure or degree of alteration are arranged under the principal species as varieties. Chapter second commences the systematic treatment of rock classes, starting with the most basic. The suggestion of Reyer, to consider the meteorites as eruptive rocks more basic than any normally found near the earth’s surface, is wisely followed. Spe- cies 1, Siderolite, is made to include all masses of iron, either native or in its secondary state as magnetite, hematite, etc., which are not of chemical or secondary origin. This species is of course principally represented by meteoric iron. Species 11, Pallasite, includes such original, eruptive, celestial or terrestrial rocks as contain a large amount of native or oxidized iron inclosing other minerals. Twenty-two meteoric pallasites are mentione terrestrial variety of pallasite is described the so-called “ cumber- landite ” from Rhode Island, an apparently eruptive mass of mag- netite full of crystals of olivine, feldspar, etc. Analogous to this is Sjoren’s “ magnetite-olivinite” from Taberg, in Sweden. Chapter third deals with Species 111, Peridotite. This name was given by Rosenbusch to massive rocks composed essentially of olivine together with various pyroxenic minerals. The author classifies these as follows : Variety 1. Dunite = olivine + picotite. “ 2, Saxonite = olivine + enstatite. “ 3. Lherzolite = olivine + enstatite + diallage. “« 4, Buchnerite = olivine + enstatite + augite. “ 5, Eulysite = olivine + diallage (= “ Wehrlite gf « 6. Lione = olivine -+ augite. Serpentine is derived by alteration from all of these. Eulysite is a name that was originally applied to a rock very rich in garnet, and it is difficult to see why it is preferred to the German term wehrlite, used for olivine-diallage rocks. Forty meteoric peridotites are enumerated, following which is a section devoted to the origin and character of meteorites in general. The “chondri” are regarded as spherules due to crystallization, and the meteorites themselves as having probably been thrown off by the sun. Then succeeds the description of many terrestrial peri- dotites and serpentines, with general remarks on their character and origin. Considerable space is devoted to the relations be- 500 General Notes. : [May, tween nt and chromite. Both are translucent with a brown color when sufficiently thin, but the latter only with considerable - difficulty. The suggestion is made that the chromite may be an alteration-product of picotite. Chapter fourth deals with the fourth rock-species, Basalt, of which, however, only such as are of meteoric origin are treated in the present portion of the work. Pages I-xxxul at the close of the book contain valuable tables of all the chemical analyses hitherto made of the rocks described. Eight plates with forty-eight colored figures represent the microscopic structure of these same rocks in an admirable manner MINERALOGICAL Notes.—Quartz. Professor G. vom Rath, of the University of Bonn, has recently made a valuable contribu- tion to the literature of American mineralogy by his studies of the quartz crystals from Alexander county, N. C., material for Kunz, of Hoboken. The crystallography of these quartzes is very varied and complicated, and the writer does not hesitate to pronounce this American locality the most interesting one thus far known in the world.

The real optical angle, 2V,, is 55° 20’. These results agree very closely with those obtained by Hjortdahl. ans Thürach' has contributed an interesting paper on the wide distribution of zircon and certain titanium minerals as microscopic rock-constituents. Decomposed rocks were especially investi- gated, from which these minerals were the more easily separated, Rutile, anatase, brookite and pseudo-brookite were all identified, Tourmaline, staurolite, garnet and some other minerals are also spoken of in the same connection, and a long list of localities given where all these substances were observed. Kal s finds that in certain rocks, especially nepheline-basalts from Ran- den in the Hegau, Baden, and from Tharand in Saxony, twins of olivine are quite common. The twinning plane is a brachydome whose angle over OP is nearly 60°, as was observed by vom Rath in free crystals of monticellite from Mte. Somma. Knop’ has made a thorough chemical study of the augite occurring in the various rocks of the Kaiserstuhl in Baden. One group is inter- esting on account of their'containing TiO,, the amount sometimes exceeding four per cent. This would naturally be supposed to isomorphously replace SiO., but on account of the violet color of the augite in which titanium is most abundant, it is suggested that this element may also be present as Ti,O;, replacing ferric iron. Schuster* adds over 200 pages to his former paper on the crystallography and structure of danburite, making his numer- ous and careful measurements the basis of general conclusions regarding the nature of forms possessing very large indices, to which Websky has applied the name “ vicinal-planes.” For the many important results obtained, reference must be made to the original article. Vicinal-planes are found (p. 490) to possess a defi- nite relation to some principal plane having simple indices, wi which they are associated. This relation is a genetic one. Vicin- al-planes are regarded, so to speak, as “induced” by the joint action of two forces, one exercised by the new molecules in their effort to form a really new plane and the other exerted by the old plane to retain its exact position. The crystalline form of - the element thorium has been for the first time determined by Brogger. Although apparently rhombohedral, the minute crystals (only 0.15™™ wide and 0.015™™ thick) are really ular, being a. combination of a cube and octahedron.

If the section be A A. Showing the branching of the bundles at the node, seen longitudinally. 2, a horizontal section of a portion of the bundle ring in a node made radially through one of the teeth of the sheath or rudimen- tary leaves, a bundle is seen to pass down and unite in the node with one of the bundles of the stem. Fig. B, a horizontal section in the node of a portion of the bundle ring, shows how this leaf bundle originates. It is seen that the bundle of the leaf is derived, not by a simple separation of a portion of the outer phloem, part of the bundle in the stem, but that it originates where that bundle begins to divide, and in such a manner that its vessels are continuous with the xylem of the divided bundle. Each bundle of the stem therefore divides at the node in three parts—two lateral portions, each with xylem and. phloem, which by rearrangement continue the bundles of the stem, and a central part which bends outward into the leaf.

Tur FERTILIZATION OF CUPHEA VISCOSISSIMA.—The entire plant is clammy pubescent, especially the stems and calyces. There are six petals, purple, the two upper ones about twice the size of the rest, the four lower ones being placed along the lower edge of the calyx (Fig. 1 A). The lower part of the calyx near the throat is inflated, and the base is spurred (Fig. 1 B). On the RRAN PAV CAA a a dA d NEWA A nA : ESE 1 Wi a 7 t FOT E sth \ hi MELATI } ti i \ l "i J y Fig. I.

THE INTERNAL CAMBIUM RING IN GELSEMIUM SEMPERVIRENS.— Dr. J. T. Rothrock, at the meeting of the Botanical Section of the Academy of Natural Sciences of Philadelphia, held February 9, 1885, called attention to the internal cambium ring in the stem of Gelsemium sempervirens. It might well be designated as the inner cambium. His attention was attracted by the fact that in a stem of three-eighths of an inch diameter, the pith was actually less in diameter than in a ¢wig of a quarter the size of the stem. Microscopic examination showed that in the larger stem there were ordinarily four or more points, at which a well-defined swel- ling curved inward from the circumference of what should have been the pith-cavity. These swellings resolved themselves when closely examined into: ‘I. Toward the center an imperfectly defined membrane, resem- bling cuticle, which was not always present. 2. One or more rows of large cells like the parenchyma we find under the epidermal layer. 3. Several poorly defined layers of smaller cells, such as often mark the limits of growth in bark. 4 The frequent presence uf bast fibers or of sclerenchyma cells, : 5. An evident layer of thin-walled, square cells, closely resemb- ling, though somewhat smaller than those of the external cam- bium. They showed signs of division, which indicated that they were still a living tissue. _ in the very large stems a smaller pith than in those of moderate _ size. In this there was nothing comparable to the inner cambium. He also remarked that for the past two winters his attention had __ been called to the presence of considerable quantities of chloro- _ phyllin the pith of Lycium vulgare. This was not confined to _ the smallest stems, but was found also in those of over a quarter of an inch in diameter, and where of course a considerable belt of 1885.| Botany. 505 hard wood was found between the pith and the outer zone where chlorophyll is expected. It was also observed in Lycium that the chlorophyll was not in the form of bodies, but diffused in character, as it is said to be in some infusorians. In Lycium the cells of the pith showed, in winter, abundance of protoplasm which had the nucleus on one side and very striking bands ex- tending thence across the cell to the further side.—FProc. A. N. S. Phila. STRASBURGER’S BOTANISCHE PrActTicuM.—Abouta year ago this book appeared in Germany, where it has received many favorable notices, as an excellent work for the laboratory student. The book is so valuable that it must soon be translated, but in the meantime we may well give an outline of what it contains. After an introductory chapter devoted to the microscope, various kinds of apparatus, raga peui taray etc., etc., the work is divided into thirty-four “tasks,” in which partic ular subjects are taken up. The aim ol the GE is to tad the student at once in microscopy and botany, rightly believing that the art named can be best learned in its application to the science of plants. As far as possible the plants selected are common and easily obtainable ones. The illustrations, 4 Daig there are 182, are all new, and are made especially for t e general sequence me subjects is as follows: Starch, ale- urone, protoplasm, chlorophyll and other coloring matters; crys- tals; anatomy of the root of sugar-beet ; fruit of pear ; epidermis and stomata of Iris, Tradescantia and other plants ; hairs of vari- ous plants; fibro-vascular bundles of Indian corn, oats, palm, Ranunculus, Aristolochia, etc., etc.; secondary wood, anatomy ot stems of Scotch pine, linden, ivy, locust (Robinia), pumpkin, etc., etc., running through twenty “tasks” or chapters. A couple of chapters are devoted to the structure and reproduction of mosses, five to the fungi and alge, one to the reproduction of pterido- phytes, another to that of conifers, and five to that of phanerogams iy pa smaller edition has appeared in Europe, but this we have not yet seen. We trust that a translation of either the larger or the smaller work will be placed before the English-speaking stu- dents of this country. There is certainly room for such a book here.— Charles E. Bessey. - Tue Pampas.—In answer to the statement of Professor Asa Gray, following Darwin and Ball, that the pampas of South America are treeless because the only country from which trees could be derived could not supply species suitable to the soil and climate, Mr. Edwin Clark puts forward, in a letter to Mature, what he, from long residence and observation, believes to be a more probable cause or series of causes. From the absence of rivers or water storage, periodical droughts paty occur in the ~ 506 General Notes. [May, summer, and at such seasons the droves of horses and cattle and the numerous aboriginal wild rodents destroy every vestige of vegetation in their efforts to live, the cattle even tearing out the roots of the pampas grass. The existence of an unprotected tree is impossible. Nothing survives save thistles, some grasses and clovers, a few poisonous plants, thorny dwarf acacias and wiry rushes. The extensive introduction of European plants has only added to the flora of the pampas a few species, such as two this- tles that are unassailable by cattle. Yet the soil is fertile and trees grow luxuriantly wherever they are protected. BotanicaL Nores.—The odd tree known to the Mexicans by the name of Ocotilla, and to botanists as Fouquieria splendens, a native of the Rio Grande plateau region, has been made the subject of chemical studies by Miss Helen C. De S. Abbot, of the Philadelphia College of Pharmacy, the results of which have lately been published in an eight page pamphlet. A new vegeta- ble wax was discovered in the bark, to which the name of Ocotilla wax was given. Dr. Farlow’s paper on the Synchitria of the United States, in the March Botanical Gazette is of unusual interest. It contains déscriptions of all the species known to exist in the United States, ten in all. The Botanic garden of Buitenzorg, Java, founded in 1817, consists of ninety-one and a half acres, and contains more than nine thousand species of plants, each represented by two specimens. Connected with the garden is a botanical museum, containing the herbarium, a collection of vegetable products, and the library, with facilities for drawing and photography. All this is in far-off Java! When may we hope for that kind and amount of state help in this country which will enable our botanists to begin the making of botanic gardens worthy of the name? As showing the tendency in our best universities we note that, according to an item in the Gardeners’ Monthly, the University of Michigan “has established a chair of forestry in connection with its other branches of education.” — The University of Nebraska has made an appropriation of five thousand dollars for procuring apparatus and collections for its department of botany.

Michael read a paper “ On the Life-histories of some little-known Tyroglyphide.” In 1873 Michael has found the acarus in England under the bark of reeds, destroying the reeds, not feeding on any insect, and con- cludes that it is probably a feeder on various kinds of bark, not on animal life. He has traced the whole life history. The male (previously unknown) presents the exceptional features possessed by the male of Tyroglyphus carpio, discovered by Kramer in 1881, and the hypopial nymph has been figured by Canestrini and Fan- zago in 1877 under the name of “parasite of an Oribata,” but without explanation. Mr. Michael finds in the life history of this 508 ` General Notes. © [May, hypopus a confirmation of his views that the hypopial stage is not caused’by exceptional adverse circumstances, as Mégnin sup- oses; but is an ordinary provision of nature to insure the distri- bution of the species, which it is intended to call Zyroglyphus corticalis. Mr, Michael also called attention to the prevalence of Rhizoglyphus robini on Dutch bulbs imported into England in 1884, and to the destructive nature of that species, and the damage it did to hyacinth, dahlia and Eucharis bulbs, &c., and recommended that imported bulbs should be carefully examined, —English Mechanic. FIREFLY Licut.—MM. Aubert and R. Dubois have recently made a number of interesting observations on the light emitted by “pyrophores,” or fire-bearing insects of the family Elateres, genus Pyrophorus. These pyrophores have three luminous organs, one situated at the ventral part, and two at the superior part of the prothorax. The last are always visible, and were sub- mitted to the tests. The light was produced by rubbing the in- sect with a light brush, and was examined by means of an ordi- nary spectroscope with a prism of very refrangible glass and a micrometer. The spectrum was very fine, continuous, and show- | - ing neither brilliant nor dark rays. This ‘peculiarity has already been pointed out by Pasteur and Gernez, who studied the light from a pyrophore belonging to the late Abbé Moigno, editor of Les Mondes. The spectrum occupied about seventy-five divisions of the micrometer, and extended on the red side to the middle of the interval which separates the rays A and B of the solar spec- trum, and on the blue side a little beyond the ray E. When the intensity of the light varied, its composition changed in a remark- able manner. When the brightness diminished the red at orange disappeared entirely, and the spectrum consists of gree and a little blue and yellow. The green rays lasted longest. The contrary took place when the light grew in brightness, the green appearing first and spectrum extending a little on the blue and a great deal on the red side. The least refrangible rays are, there- fore, emitted last. No other luminous source known appears to behave in like manner. The only case which bears a resem- blance is that of sulphate of strontium becoming phosphorescent under the action of light at a glowing temperature. As the tem- perature rises, rays less and less refrangible appear in the spec- trum, but at the same time, as Edmond Becquerel has shown, the ' dess refrangible rays disappear. When the light of the organ be- _ gins to appear, the central and forward part only of the organ is _ luminous. Itis only when the light is very bright that the per- iphery of the organ is luminous, and then the red rays are visi- oe ble. The light was found to give photographic images on a gela- __ tino-bromide plate; the insect being two centimeters from the ae plate, and the time of exposure reduced from an hour to five _ minutes. The photographs show that the light of the pyrophore 1885.] Entomology. 509 is capable of producing intense chemical effects, if the smallness of the quantity emitted be taken into account. The light also de- termines the phosphoresence of sulphate of calcium, after an expo- sure of five minutes; and eosine and azotate of uranium are rén- dered fluorescent by it. The foregoing is taken from an exchange; the first spectro- scopic research in firefly light was those of Professor C. A. Young, published in this magazine, vol. 11, p. 615, 1870. USE OF AN ADHESIVE FLUID IN JUMPING INSECTS.—Dr. Dewitz has described the use of a sticky fluid by insects in jumping. A Cicada in a closed glass tube is able to jump from the bottom on to the cover, and from one vertical side to the other, turning in the air; the contingency of having to jump on to vertical sur- faces, or the under side of horizontal surfaces, occurs also in Na- ture—viz., in the case of stems and leaves, which are, moreover, smooth, so that claws are ineffectual to support the insect, and sucking-disks would: probably not act with sufficient rapidity. Now, the leaping spiders possess a well-developed pedal adhesive apparatus, by the aid of which they can remain attached to the surfaces on which they alight; the glands which secrete the liquid open all over the balls of the feet, and are especially numer- ous at their bases. EntomotocicaL Notes.—We glean from the Zod/ogical Record for 1883, such notes as are of general interest. Klemensiewicz publishes detailed observations on the glands of the skin of cater- pillars. As the respiration of insects, says Langendorf, depends on abdominal movements, it may continue after the removal of the head. The number of respirations is increased by heat. Tobacco-smoke and chloroform lead to intermittent, but more or less rhythmical respiration for a time. The head and prothorax may be removed, and the respiration will continue; and if the abdomen of a dragon-fly is cut to pieces, respiration will continue in them, thus showing that each abdominal segment possesses its own respiratory center——Osborne finds that in the Euro tra and those fed en honeysuckle forming pale-greenish cocoons.

[ May, test the power of bees to return to their nests when carried to a distance ; a considerable number returned safely. Ammophila jursuta, says Fabre, searches for the larve of Agrotis segetum, which are detected under the surface of the ground by some apparently unknown sense. The larva is carefully paralyzed in every segment before being buried, which leads the author to conclude that the Ammophila originally preyed on insects more easily paralyzed, and as it gradually attacked larger insects, its in- stincts enlarged, and became hereditary——W. F. Kirby finds that hybrids between Smerinthus ocllatus and populi usually show traces of hermaphroditism, which seems to indicate that herma- phroditism is encouraged by hybridity, and that the usual sterility of hybrids may be due to this cause. ZOOLOGY. ANOTHER VORTICELLA WITH TWO CONTRACTILE VESICLES.—In the NATURALIST for August, 1884, the writer described a new infusorian belonging to the genus Vorticella, under the name Vorticella lockwoodu, one of the peculiarities of which was the possession of two contractile vesicles, that being the first recorded instance of the occurrence of more than a single pulsating vacuole in any of the numerous species. Now, however, I desire to state that a similar arrangement obtains in the well-known Vorticella monilata Tatem, a species originally discovered in English waters, and by no means uncommon on the continent of Europe or in this country. It therefore seems somewhat surprising that the presence of the two vesicles in this widely distributed form should have hitherto eluded observation. The species occurs in this locality in some profusion, a colony recently taken attached to Myriophyllum from my aquarium being formed, by actual count, of two-hundred individuals, another of eighty-three, smaller col- lections not being rare. With these I have been able to positively determine and demonstrate to a friend the presence of two con- tractile vesicles which, when the vorticella is in the proper posi- tion, are distinctly visible without a change of focus. The fact of their presence is of interest since it is a point in the anatomy of th inute creat t previously noted.—Dr, Alfred C. Stokes, Trenton, N. F. CUVIERIAN ORGANS OF THE COTTON-SPINNER.— Professor F. Jeffrey Bell gives a technical account of this almost unknown British Holothurian, which is of interest as being the only true —that is, aspidochirotous (or with shield-shaped tentacles)— member of the class which is known to occur in British seas. The organ of most’ importance is that which produces the sticky _ Secretion from which these animals have obtained their name, and which makes them objects of much dread to the Cornish fisher- = men. The producing or cuvierian organs are described as form- _ ing a solid mass which occupies a large portion of the body- 1885. | Zoölogy. 511 cavity, and which is made up of a number of separate tubes; a small coiled portion was found lying in the cloaca as if ready for ejection. A small piece of a tube, measuring only 2.5™™ was found even after twenty years’ immersion in spirit, to be capable of extension to twelve times its own length; while, when treated with water, the attenuated thread swells up to seven times its own breadth. “We can thus understand that an animal at whom these threads are thrown should, as it attempts to escape, lengthen the threads which, at the same time, coming into contact with the water, would be swollen out transversely as they were extended longitudinally.” Professor Bell thinks that the observations con- firm the view of Semper as to the protective or offensive charac- ter of these organs, which, by Jager and most later anatomists, have been thought to be renal in function. In a subsequent note Professor Bell states that six threads, any one of which was only barely visible, were capable of supporting a weight of nearly a thousand grains; and quotes a letter from a correspondent to say that the black holothurians near Porto-Fino, emit a tangled mass of white threads so sticky and in such quan- tity that it was difficult to free the hands from them.— Fournal of the Royal Microscopical Society, December, 188 4. EartTH-Worms.—An interesting paper on the habits of earth- worms in New Zealand is contributed to the New Zealand Insti- tute by Mr. A. T. Urquhart. The species are not named, but with such wonderful opportunities as Mr. Urquhart possesses for making a collection of these, may we hope that, in addition to his following out his observations as to their habits, he will also advance science by making a careful collection of the forms and placing them in the hands of some of the able naturalists of the Auckland Institute for description? It will be remembered that Darwin assumes that in old pastures there may be 26,886 worms where the return of worms was a blank, the walls were crow with worms. Asa result there was an average of eighteen worms per square foot, or 784,080 per acre. Although this average is very striking when compared with that of Hensen, it is worthy of note that the difference between the actual weight of the worms is not so marked. According to Hensen, his average of 53,767 512 General Notes. [May, worms would weigh 356 pounds, while Mr. Urquhart finds that the average weight of the number found by him came to 612 pounds 9 ounces.. Scientific American, DEEP-SEA EXPLORATIONS OF LAST SUMMER BY THE U. S. FisH Commission.—Professor Verrill reports that the zoological. results this year were of great interest. Many additions to the fauna of great depths were made, anda large proportion of them are undescribed forms. Someofthe fishes were of great interest. Huge spiny spider- crabs (Lithodes agassizii) over three feet across were taken in 1000 to 1230 fathoms, and another very large crab (Geryon) occurred in great abundance in 500 to 1000 fathoms, while in 2574 fathoms a large and strong crab-like creature (Munidopsis) was taken. any curious shrimp, some of them of large size and brightly colored, and often with perfect eyes, occurred in most of the deepest dredgings. Several very interesting new forms of star- fishes, ophiurans, and holothurians were dredged, some of them in large quantities, even in the deepest localities. Several inter- _ esting new forms of corals, gorgonians, sea-pens, and allied forms so occurred. Numerous specimens of huge sea-urchins with flexible shells (Phormosoma uranus) were obtained from several different stations, in 600 to 1100 fathoms. Some of these are about ten inches broad. One sea-urchin (Aspidodiadema), not before observed north of the West Indies, was taken in 991 fathoms. Most of the deep-sea star-fishes belong to the genus Archaster and other closely related genera. Some of these, like A. agassizii and A. grandis, were taken in large numbers, several hundreds in a single haul. And the same often happens with several of the ophiurans and sea-urchins. One interesting stalked crinoid (Rhizocrinus) was obtained in 2021 fathoms. any additions were made to the Mollusca. In July, Professor Verrill published a general list of all the deep-water Mollusca taken in the gulf stream region off this coast, up to theend of 1883. That list included 338 deep-water species and 42 that inhabit the sur- face waters. This year about 25 deep-sea species and about 8 from the surface were added to the list, making the total number Over 400 species. Among the new forms discovered this year are four or five species of cephalopods, some of them very remark- able, and representing new genera. There were some very inter- esting new shells, some of them of good size and well developed, _ from below 2000 fathoms. Most of the larger and finer ones from the very deep waters belong to the Pleurotoma group, but some large species are allied to,Sipho (or Fusus) and to Dolium. _ Numerous specimens of three rare species of brachiopods were also dredged from below 1000 fathoms. These are Discina atlantica, ` Waldheimia cranium and Atretia gnomon. The latter has not been known before from this side of the Atlantic. __ Anatomy oF a Catrisa.—Professor R. Ramsay Wright, with _ Professor J. P. McMurrich, A. B. McCallum and T. McKenzie, 1885.] Zoology. 513 have published in the Proceedings of the Canadian Institute of Toronto “ Contributions to the anatomy of Amiurus.” The papers erve as a contribution to the morphology of a comparatively little known family of fishes, and will also be of use to teachers of comparative anatomy. The skin and cutaneous sense-organs as well as the nervous system and sense-organs are described and figured by Professor Wright; the osteology and myology by Professor McMurrich, the alimentary canal, liver, pancreas and air-bladder by Mr. McCallum, which Mr. McKenzie has worked out the blood-vascular system, ductless glands and urogenital system. The work comprises 206 pages, and is illustrated by eight folding heliotypic plates. Professor Wright describes certain structures which are appa- rently comparable to the nerve-sacs of the ganoids; he also dis- cusses the relationship between the air-bladder and the auditory labyrinth. The work is another of the monographic essays now appearing from time to time, and affords the modern student aids and facilities such as were entirely unknown a generation ago. THE SPIRACLES OF AMIA AND LEPIDOSTEUS.—My note on this subject in the February NATURALIST requires modification, in so far as what I took to be the oral aperture of the spiracle in Amia is really the aperture of a canal in which the pseudobranchia lies, and into which the spiracular cleft opens further forwards. The pseudobranchia of Amia is homologous with the upper (non-res- piratory) part of the opercular gill in Lepidosteus ; both are in- nervated by the anterior branch of the glossopharyngeus, but the pseudobranchia of Lepidosteus is free, while that of Amia is con- cealed in what may be termed a pseudobranchial canal. The sin- gular continuity of this canal with the spiracular cleft induced me to believe that I had found evidence to justify Dohrn’s criticism of Gegenbaur’s views as to the homology of the pseudobranchia of the Teleosts, but I am now convinced that the condition of the rts in Amia proves Gegenbaur’s position to be correct.—R. Ramsay Wright, University College, Toronto, February ro, 1885. BirDS OUT OF SEASON—A TRAGEDY.—Our winter so far has been one of unusual severity, such low temperatures as — 20° to — 35° having prevailed quite often. Whole weeks have passed in which the mercury has not risen above zero! But during all this time, until the afternoon of the 18th instant—‘a chewink” (Pipilo erythrophthalmus) has lived about my orchard and barn- yard. I am unaccustomed to seeing much of this species, except in early spring, upon their return from the South. It br here, but is a very quiet bird through the summer and autumn— at least, it has only been upon rare occasions that I have seen it, But soon after winter set in I saw the one in question in the barn- yard, where he seemed to be feeding upon some scattered grain Later I found him one very cold afternoon in a “ straw-built shed, VOL, XIX.—NO, V. 33 . , 514 General Notes. [May, where I easily caught him. After looking him over, and com- paring him with Dr. Brewer’s lucid description, I let him go. Catching him did not seem to have caused him any alarm or dis- comfort, for he remained about the premises quite as tame and sprightly as usual. In addition to the chewink, a robin has also been a frequent visitant here. We saw him some days ago, and again last night, when the mercury was down to — 20°. But it is not at all un- usual for robins to be here in winter, though I do not remember having ever seen more than one at a time. On the afternoon of the 18th instant, our dear little chewink, which we had come to regard with great solicitude, met with a very sad fate. Going into the barnyard, I saw a couple of birds dart down to the side of a hay-stack. One was a jay, and at the first glance I thought the other was also. But in an instant it occurred to me that the jay was killing the under bird. I sprang forward hoping to rescue it. I was just an instant too late—for the jay picked up the bird, now dead, and flew away with it! The load was a heavy one, and as the cannibal flew off across a ravine, it bore him down almost to the ground. The quick glimpse I had of the glossy black head and back, the chestnut sides, and the white under parts, showed that it was our poor chewink—whose fortitude in braving our terrible winter had met with a sad requital. I have always defended the blue jays, though I know they are addicted to a great deal of “crooked- ness” in their treatment of other species of birds; but this inci- dent has quite disgusted me with them.— Charles Aldrich, Web- ster City, lowa, Fan. 29, 1885. How FAR DOES THE JERBOA Jump?—On page 71, of his most entertaining volume, A Naturalist’s Rambles about Home, Dr. Charles C. Abbott, in speaking of the pretty “kangaroo or Jumping-mouse,” quotes Godman to the effect that it leaps “five or six feet at every spring;” but expresses a doubt on the subject. He says: “Without the means of determining this point, I should judge that one-half that distance was more nearly correct.” While living at my old boyhood home, in Cattaraugus county, New York—forty years ago—I used occasionally to see one of these very interesting little animals. The first one I ever saw was in the meadow, where I was raking hay with a common, old-fashioned hand-rake. The mouse made a sudden spring, and “went for it” with my rake. After chasing it two or three rods I hit it with the rake-head and killed it. My recollection is very distinct, that it “leaped at least five or six feet,” at tl —though it appeared to tire out very quickly, reducing the =ngth of its leaps to not more than two or three feet. I conclude o that both writers have recalled their observations correctly, and -that the condition of the animal, possibly also its age, may deter- mine its jumping capacity. I remember that in this, as in other A 1885. ] Embryology. 515 instances, each jump was made in a different direction from the last, so that it was a matter of some difficulty to pursue the little creature! I was exceedingly interested in this first capture— never having seen or heard of one before. One of our farm hands told me that it was a “kangaroo mouse.” After that I saw one occasionally, and my recollection is very clear that Godman does not overstate its ability to jump. I have never seen or heard of one in this region.— Charles Aldrich, Webster City, Iowa, March 5, 1885. EMBRYOLOGY .! ON THE PROBABLE ORIGIN, HOMOLOGIES AND DEVELOPMENT OF THE FLUKES OF CETACEANS AND SIRENIANS.—We have seen that the development of the Physoclist fishes (Am. NaTJRALIsT, 1885, pp. 315-317), shows that the translocation of the pelvic fins for- ward is accomplished in some forms in about twenty-four to forty- eight hours, to a position more or less in advance of the pectoral, If a limb-fold can be translocated forwards in a vertebrate embryo from its archaic site, there is no reason to doubt that under cer- tain conditions it might be translocated in the other direction or backwards. A process of translocation of the distal end of the pelvic limbs seems to have occurred in the cetaceans, as a conse- quence of which the pes has acquired a new position far to the rear of that which it occupies in normal mammals, and this seems to have been accompanied by processes of atrophy in some direc- tions and hypertrophy in others. _ The researches of Struthers, Flower, Reinhardt, Eschricht, Kaup, Lepsius, Howes and Wilder, leave no doubt as to the fact that the different rudimentary structures which these anatomists have detected, unequivocally point to the conclusion that, the cetaceans and sirenians have descended from Mammalia which possessed more or less perfectly developed ambulatory limbs, which fitted them at least for an amphibious or partially terrestrial existence. This conclusion is, I believe, generally accepted by recent authorities. All recent writers, amongst which. may be named Flower, Huxley, Owen, Claus and Parker, unequivocally declare that the hind-limbs of the whales and sirenians have been so completely suppressed, that no rudiments or vestiges of any kind have re- mained to indicate outwardly that these creatures ever possesse such appendages, the evidence that they did once possess hind- limbs resting for them rather upon the presence ofa rudimentary pelvis with much reduced limb-bones in a few forms of Balznoi- ea and in Halitherium. eee From this view the-writer must dissent, having independently arrived at conclusions in reference to the homology of the flukes 1 Edited by Joun A, Ryper, Smithsonian Institution, Washington, D. C. 516 General Notes. [May, very similar to those published by Professor Gill’ in 1882, who regards these characteristic structures as having been derived _ from greatly hypertrophied integuments of hind-limbs analogous to such as are developed, for instance, to the hind-limbs of the eared seals, while the osseous elements have been inversely atro- nected with the organs of generation. It may, I think, be re- garded as a fact that there is no evidence to show that develop- ment does not attempt to recapitulate in a disguised form, in the cetacean fœtus, the outgrowth of the hind-limb as seen in a normal mammalian embryo. In the mammal the pectoral limb is the first to appear, the pelvic appearing last. If the flukes be regarded as the outward vestiges of hind-limbs or pedes, then will the embryos of ceta- ceans and sirenians conform to this law presiding over the order of appearance of the limbs, which, so far as I am aware, is regnant without exception within the limits of the vertebrate class. The dorsal fin with which the flukes have so often been mistakenly compared, is not present in all cetaceans; is absent in all sirenians; is not constant in position in different genera of the former; is sometimes a mere carina, dorsal ridge or hump; its vascular an nerve supply is different from that of the flukes; it develops after the latter, showing that it is a later acquirement ; it has absolutely no connection with muscles directly or indirectly by tendons as have the flukes, so that I regard the comparison of the dorsal fin, which is a mere dermal fold, with the flukes, as expressing a mis- taken apprehension of anatomical homologies, and not justified in the face of the fact that the flukes are never absent, and always appear laterally or serially in the position of a hind limb-fold, _ though backwardly displaced. It must, however, be stated that I distinctly disavow the affirmation that the flukes are homologous with more than the pedes of normal forms. The older views which intimated that the flukes were the representatives of limbs or of feet, it is not worth while to discuss, as these writers did not possess the data upon which to base any reasons for their opinions, which seem to have been in the main intuitional. The hypothesis which is offered to account for the flukes as the distal vestiges of limbs rests upon the following arguments :—1. The mode of outgrowth of the flukes in the embryo, prior to the dorsal fin, at the end of the sides of the tail, at first as a pair of low rounded lobes or folds of skin, containing mesoblast, which become gradually falcate, and which expand posteriorly so as to leave a notch over the end of the tail between their inner edges. The hind margin of the flukes answering to the terminal border _ of the pes or the ends of the suppressed toes or the integuments extending beyond them, and their anterior margin to the outer _ n Scientific and popular views of nature contrasted.

The existence of a small median papilla, ac- cording to Wilder, at the extreme end and under side of the tail of the foetus of the manatee, representing apparently the last vestige of an exserted tail extending beyond and behind the fluke © folds of this type, in which the flukes are in fact rudimentary. 3. The fact that the osseous elements of the limb have atrophied ex- actly in the reverse order in which they appear in the embryo, or from without inwards, that is, from behind forwards in cetaceans and sirenians, because in both, the hind-limbs have been rotated or extended permanently backwards distad of the knee-joint. 4. The structure of the embryonic fluke-folds or diverticula filled with mesoblast comparable to that found in the limb-folds of other vertebrate embryos, these limb-buds representing structures which have survived translocation and made an attempt to im- perfectly recapitulate the development of part of the limb. - The above headings present the embryological argument. The other data are anatomical and are mainly based on a comparison of the pinniped and cetacean types. Admitted that the cetaceans are descended from land forms, we would naturally look to types of amphibious habits and poorly adapted for progression upon land to furnish the first indications of modifications which have been carried to an extreme degree in the former. Traces of the beginnings of such modifications we actually find in pinnipeds. In the pinnipeds, the hind limbs, from the knees, have been rotated backward and included by a continuation of the integu- ment which invests the body together with the tail, leaving only the last two or three short caudal vertebræ exserted or projecting into a caudal integumentary pocket, lying between the distal parts of the backwardly extended limbs.. This process of inclusion, if carried to an extreme stage, would finally cause the whole of the tail to be lost to sight outwardly, leaving only the metapodial and phalangeal parts free, As a result of this arrangement in the pinnipeds certain muscular insertions of the limb muscles have been moved backwards, and the hyposkeletal flexors of the trunk have become more powerful; the abdominal muscles extending over the knees have restricted the movements of the femur.- As a further result of this restricted movement the pelvis has to degenerate, the symphysis pubis become less defined, and the femur shortened. We are therefore, I submit, the actual witnesses of a process in the pinnipeds which if carried still further would bring about the condition now found in living cetaceans. The pedes in pinnipeds have been hypertrophied together with the metapodial and phalangeal elements, but are not the fingers also lengthened and their joints multiplied in the cetacean manus ? In the Plesiosauri, Ichthyosauri and Lyrifera or true fishes, the 1 » or increase of limb-elements comparable to p langes, with a corresponding shortening of the proximal bones in contact with 518 General Notes. | May, the shoulder and hip-girdles. Manifestly the pes of a form like Megaptera, if mobile, would require a system of phalanges as powerful as those in the manus, but the pes is not mobile in any cetacean, on its own base, as is the fore-limb, but is rigidly affixed to the sides of the end of the tail and incapable of independent movement, hence the atrophy of its bones. The only evidence remaining to indicate that the pedes or flukes of cetaceans were once possessed of well-developed phalanges, is the distribution of the dorsal and ventral interdigital arteries, the arrangement of these in fact indicating that there was a great inequality in the length of the digits of the pes, the same as we now see in the manus, thus leading to the conclusion that the foot-structure of the ancestral or protocetacean type was so far different from that of the pinnipeds. the tail, which, with the total abandonment of the land by the animal, would become stronger and its centra greatly developed, carrying the pedal folds or flukes still farther rearward, and thus increase still more the interval between them and the rem- nants of the pelvis. At the same time, the muscles of the tail would become greatly developed, so that in the cetaceans we actually have the spectacle of an animal type which has descended from a land form with a degenerate tail again acquiring a tail of the functional importance of that of a fish, but structurally very dissimilar, especially as regards the arrangement of its muscles, which are not homologous with the muscular somites of a fish’s tail. The pes thus becomes the only outwardly apparent part of the hind limb, just as the manus is the principal part exserted in the fore-limbs of cetaceans, where some of the muscular inser- tions have also been shoved outward or into a more distal an effective position. The inclusion of the end of the tail of ceta- ceans between the flukes has also differentiated the caudal verte- brz of the latter into two distinct and well-marked series, so that the centra, as respects their vertical diameters, do not taper from the sacral region backward, as in other mammals, but only from in front of the flukes backward. ; -he arrangement of the vessels of the manus and flukes is 1885.] Psychology. 519 Finally, it may be said that the rudimentary tibia, when present, is directed backward in the cetaceans just as in pinnipeds, show- ing that if it were fully developed and prolonged it would carry the pedes far behind a vertical line drawn through the hip-joint. There is also other evidence that the inclusion of the hind limbs in the whales has occurred in much the same way as in pinnipeds, for example, the femora are adducted to a remarkable degree in Balena, according to Struthers, showing that the encroachment of other parts must have been the principal cause of such adduc- tion. The femora of Halitherium seem also to have been direct- ed backward toward the flukes, according to the figures given by Lepsius. The translocation of the pedes of cetaceans has been accom- plished through an extended phyletic series and was not sudden or partially saltatory as in the case of the pelvic limbs of embryo physoclists. The translocation in the first case was due to the ackward extension of the limb, outwardly carrying only the pes away from its original place, in the latter the whole limb is shifted together with the girdle. In cetaceans there has been little or no shifting of the pelvic girdle, its detachment from the vertebral column being due to the atrophy of the ilium. The extension backwards of the limbs and pedes parallel with the caudal portion of the vertebral column, obviously began in an amphibious mam- malian type and has thus gradually brought the pedes to their present position, where they appear ontogenetically; heredity, through immediate ancestry, here, as in many other cases, greatly marring the phylogenetic record. This gradual shifting, accord- ing to the method described, completely does away with the diffi- culty suggested by Flower as to the helplessness of the animals during the transfer, which really began in forms already to a great extent helpless on land but certainly not in the water. The foregoing gives the principal anatomical and embryologi- cal grounds for regarding the flukes of Cetacea as the representa- tives of pedes translocated backward by rotation and extension of the limb rearward into a position parallel with the tail by the process of inclusion as described above, but as it is impossible to consider the evidence in favor of this conclusion in detail in this brief abstract, those interested are referred to my illustrated memoir on the subject almost ready for publication by the U.S. > Fish Commission.—/ohn A. Ryder. PSYCHOLOGY. INTELLIGENCE OF THE Limpet.—By far the larger number of lim- pets “roost” upon rocks whose only covering consists of minute green alge and millepores, together with numerous acorn barn- — acles. These last are seen to be of very unequal degrees of “ clean- ness,’ some being covered with vegetable growth, others quite white and bare. Those immediately surrounding a limpet or group 520 Generat Notes. [May, of limpets are invariably free from algz. As might have been an- ticipated, Patella is the cause of this freedom. At low tide any one on the foakout can hear a quick, regular rasping sound in all directions, and see numerous limpets slowly crawling about. Scrutiny of any particular individual shows that the rasping noise is caused by strokes of the radula, which speedily scrapes away the incrusting alge. Whilst “on the feed” a limpet moves steadily on, pretty much in a straight line, and continually sweeps its elongated snout from side to side, feeling out probably suita- ble patches whereon to graze. When such a one is discovered, it is gradually licked quite clean. Ifthe patch happens to be the sur- face of a moderate-sized barnacle, the circular lip is completely spread over it, almost tempting one to believe that the crusta- cean is about to be “ sawn out.” Such, however, is not the case, “house-cleaning” being the sole end in view. Indeed, limpets are often serviceable to one another by thus clearing away escu- lents growing upon their shells. To secure a dinner, a good deal of licking is requisite, and perhaps this habit may help to account for the inordinate length ofA ie tongue-ribbon. Certainly, it must used up at a very great But this is not the only, So aoa I believe the chief way in which the limpet feeds. ose individuals which live near large sea- weeds, such as Fucus, feed extensively upon them, as their gnawed condition testifies. I can speak confidently in this mat- ter, having caught more than one limpet in the act. The opera- tion was as follows: The edge of a thick flat part of the thallus was seized by the lip (as a traveler might commence on a colossal sandwhich), and being, I suppose, held firmly by the upper jaw, a semicircular “ bite” was gradually excavated by successive scrapes of the radula, the edges of the bite being beveled on the under side. So far as my observations extended, limpets do not feed when covered by water, but always settle down firmly before the rising tide reaches them. The intervals between which any par- ticular limpet feeds seem to be very irregular; but, as a rule, the largest limpets are apparently least fond of long fasts. In regard to the second point, the locality-sense, great doubt seems to exist in the minds of naturalists as to whether limpets go back to the same place to roost. I believe the question was answered in the affirmative long since by a Mr. King, but, as far as is known to me, he did not publish any details of his observa- tions, and this is my excuse for giving an outline of mine. Fol- lowing a neces of Mr. yya I marked a porosa of lim- ° 1885.] Fsychology, 521 The question now arises, what sense is employed by the limpet in finding its way back to its scar? The appreciation of locality displayed is certainly, for so simply-organized an animal, very e sense of sight is, evidently, out of court, for an eye like the limpet’s, consisting of no more than a sensitive cup, could do little if any more than distinguish between light of different degrees of intensity. The tentacles seemed at first sight to be ex- tremely likely organs to use for the purpose, and to decide this I excised those of two marked individuals, which were off their scars. One speedily found its way back; the other seemed con- fused by the operation for several days, but after that time was found on its scar, This shows a remarkable power of memory, unless the scar was found by accident, which is possible, as the individual was near home when the operation was performed. But even in that case the scar must almost certainly have been remembered. Thus the tentacles do not seem to be the means by which home is returned to. The sense of smell then suggested itself, and it occurred to me that one reason why limpets keep on their scars when covered by the water was to prevent the “ scent” of the track traversed from being washed off. With a view to determine this the space between a wandering limpet and its scar was carefully washed again and again with sea-water. In spite of this the limpet in question readily found its way back again. Further experiments are, however, needed, on this head, for any ordinary washing would be very ineffective compared with the rolonged soaking the tide would effect in the case of a limpet (like the one just mentioned) living some distance below high- water mark. Still some limpets live so near this last that they are covered but a very short time, and yet these remain on their scars during that time. Hence I think some other motive ably induces them to remain firmly fixed to their scars when under water. Of course they can hold on best when so fixed, and this suggests the most likely reason for the habit, z.e., to avoid 522 General Notes. [May, being washed off the rocks by the tide. Iam inclined to think that the snout plays some part in helping the limpet to get home, as this organ is extremely sensitive, and certainly plays an important part in discovering suitable food. I intend carrying on more extended observations with a view to the more complete elucidation of this puzzling question in regard to the limpet’s locality-sense, but this preliminary notice may possibly be of some interest —¥. R. Davis, in Nature for Fan. 1, 188 ANTHROPOLOGY.’ ELEMENTS OF GENERAL ANTHROPOLOGY.—Without drawing in- vidious comparisons, it would not be unfair to say that anthropo- logical science is better organized in France than in any other country. The Dictionary of Anthropological Sciences, now going through the press in Paris, is just at this moment followed by a colossal work by Dr. Paul Topinard. The first volume, of 1157 pages, entitled “Eléments d’Anthropologie générale,” relates to the history of anthropological investigations and to those special investigations which have been prosecuted upon the human body. The second part of the Anthropologie géné- rale will bring together all the matter furnished by the different branches of the natural history of man, taking into account in- structions furnished by accessory sciences, and will make a syn- thesis of these results, concluding with a discussion of man in time, his origin and his future. The second volume of the work will be the application of the zoologic method to the determination of all the types of the human species and of all the races. This will be denominated “ Anthropologie spéciale.” Without spending a word in the praise of a work which speaks for itself, we will give our readers a few of the tables not accessi- ble in any text books, but indispensable even to intelligent readers. The first six chapters are historical, tracing with great minute- ness the methods of studying man from Herodotus, Hippocrates, Aristotle and Galen down to the foundation of the Anthropologi- cal Society of Paris. The next three chapters, VII, VIIL, IX, treat of the methods to employ in anthropological research. The remaining chapters are devoted to the study of the hair, nose, color of hair, eyes and skin, cephalic indices, height, brain-weight, skull-cubage, craniometry, zodlogic characters, zsthetic charac- ters and anthropometry. In a former number of the Natura.ist we called attention to a fact, often noticed, that the method of the formation of races is in a certain sense antizodlogical. As Professor Flower observes, ' _ the methods of the formation of species are necessarily disper- 1 Edited by Prof. Oris T. Mason, National Museum, Washington, D.

As in the cosmic period heavenly bodies were thrown off by a revolving mass, so have species arisen by that isolation which is necessary to the fixity of hereditable character- istics. There seems to be a growing conviction that the first human stem threw off at least three branches to which the spe- cific law just mentioned applied. But expanding indefinitely the borders of these subspecies, if you like, soon overlapped ard set up a concrescent, concurrent movement, resulting in a diversity of races, Dr. Topinard accepts this tripartite division of humanity, de- veloped by Cuvier and enforced by Flourens and de Quatre- fages, but justifies s plan by arguments wholly his own.

With these are connected the rubber tubes, Æ and Z. - 1886] Microscopy. 529 Now when water is allowed to flow into the reservoir mentioned above, the air is forced out through A into F, and thence along the tubes D and C into B and &. As soon as the pressure in these bottles becomes sufficiently great, the liquids which they contain will be driven out through the tubes Æ and Z. If there should be any obstacle to the escape of these fluid masses, the pressure in all the vessels will rise and be registered by the height of the mercury in If now it is desired to inject, for instance the kidney of a pig, a canula made of a glass tube must be fitted securely into the renal artery and a similar one into the renal vein. The canule must be of such a size that the rubber tubes, Æ and Z, will fit them well. Heat the gelatine masses in the bottles, 8 and X, to the proper temperature and keep them so heated until the injec- tion has been finished. Special care must be taken with the tubes, Æ and /, to prevent the gelatine passing through them from becoming frozen. Now having clamped the tube, Æ, have an assistant turn on a small stream of water until the gelatine begins to flow slowly from /, If the diameter of the canula is not too small it may be held with the free end directed upward and filled with gelatine allowed to drop from the mouth of Z. Then slip Z over the canula. Unclamp the tube, Æ, and when the gelatine from # has begun to flow, slip it over the canula inserted in the vein. Then increase the pressure gradually until it has reached as high a point as experience has taught to'be safe for the organ operated on. By means of this apparatus, which will require the expenditure of only a few cents and a little ingenuity, double injections may easily be made of any organs whose veins are not provided with lves. I have made injections of the kidney whose arteries and glomeruli became uniformly filled with the red mass and whose veins and the system of capillaries surrounding the renal tubules became filled with the blue. The lungs and the liver are easily and successfully injected. I have been less successful in injecting the organs that send away their blood current through the portal vein; but I have no doubt that they too may be injected. Triple injections of the liver may be made by first injecting the hepatic artery with a green mass until the whole liver assumes a green tint, and afterwards injecting the portal vein and the hepatic vein with red and blue as above directed. The same apparatus may be employed to make either single injections or the double ection described under the FEA head of this paper, by pi clamping one of the tubes, C or D. As a matter of course care must be taken that all the corks fit tightly in the bottles, otkeeihse the internal pressure may force them out at the very moment when an accident will do the most damage.

Fifty-eight days after decapitation the worm had re- produced not only the brain, but the cesophageal collar and cesopha- geal ganglion. In one of the specimens exhibited, the lobes of the brain-mass were about one-half of the normal size; a secon had progressed further, while in a third the brain and ganglion were normal. The only perceptible difference between the re- generated ganglion and the original brain was a somewhat paler olor Feb. 1 7.—Miss Fielde stated that when twenty or more seg- ments, constituting the posterior portion of a worm, were cut off behind the clitellum, regeneration never took place at the cut end, but by the insertion of new pieces, Mr. Meehan accounted for the sparse distribution of the cedar of Lebanon by attributing it to the solidity of the cones, which never open, though the seeds are winged, and therefore designed for wide distribution. He be- lieved it probable that this close habit of the cones has only existed in comparatively recent times. The Indian species is so closely related that it probably sprang from the same ancestral stock. The only young trees which grow in a state of nature are produced from cones which rot in rock-crevices or are broken by accident. Professor Heilprin read a paper upon disputed points in geology and palzontology, with special reference to the greater adaptability of the lower forms of life to changed surroundings, and their consequent persistence in later geological deposits, as compared with the rapid extinction of higher types. Arguments were adduced in-favor of homoplassy in evolution or the origin of the same generic or even specific forms by distinct lines of ancestors, and the reappearance of extinct genera and species in subsequent geological epochs. eb. 26.—Mr. Potts described a new Hydrozoan from Tacony creek, This creature has a cylindrical body, surrounded at its free extremity by sixty or seventy papillz, but without tentacles.

It was thought that a clear central space had been seen, and that a faint channel ending in a mouth could be traced. This appears to be the most primitive form of Hydrozoan yet described, its power of motion is very slight, and how it can capture prey without tentacles is a mystery. Mr. Potts suggested that it might be the larval state of a more developed form, as it had not changed, but had budded from the base.

THe THREEFOLD NATURE oF EVOLUTION, T what level in nature does consciousness first come definitely into existence? This is one of the most difficult of the problems of science, and one which, perhaps, can never be clearly answered, At the limiting boundary of conscious and uncon- scious action it is quite impossible to tell, by any means at pres- ent at our command, whether blind force or intelligent agency is at work. Even within our own bodies it is difficult to limit the kingdoms of consciousness and unconsciousness, and equally difficult to decide that actions which seem now wholly uncon- scious were originally so. This question cannot always be de- cided by the claim that here reason has evidently been at work, and there only natural selection. For the results of reason and natu- ral selection, as applied to the modification of the body and of its habits, are singularly alike. In each case adaptation to external conditions is produced, and there can be only certain definite adaptations to each limited set of conditions. Thus if the results of two energies are of precisely the same character, it is impossi- ble to decide from these results which energy has been active. Where the change has been too rapid for the powers of natural selection, we may be sure that consciousness has been at work. But in the case of very deliberate changes we cannot positively decide to which force they are due, and some degree of conscious action may extend to a much lower level in the realm of nature than we usually imagine. On the other hand natural selection may be the sole active agency up to a somewhat high level. Evolution has its three distinct and dissimilar phases, on each VOL. XIX.—NO., VI. 35 534 | The Relations of Mind and Matter. [June, of which natural selection acts, though it is customary to apply this principle to only the second of these phases. These are the chemical, the functional and the psychical. So far as organic evolution is now concerned, chemical development has become of minor importance. Yet originally it was of supreme importance. In fact, the whole vast range of inorganic chemical development was a necessary preliminary to organic existence, and constituted the primary phase in that grand whole of evolution which is a continuous and not a broken chain. Very probably, in the primeval period, inorganic chemism yielded far more complex compounds than any it now presents, The conditions of temperature at that period, and the fluid state of many elements which are now found only as rigid solids, must have aided such a chemical activity. Even now more complex compounds than we find would doubtless exist but for a reason to be considered further on. This primeval chemical evolution may have gone on for ages without impediment, yielding steadily higher and more complex products, every fixed stage of which formed the basis for a new upward step of material development, until finally a stage approximating to that of protoplasm was reached. But long before this stage was attained, it is highly probable that functional evolution came into play, and at once acted as a check to the rapid progress of chemical development. As soon as an unstable colloid compound was thus produced, so constituted as to be subject to the disintegrating attacks of oxy- gen, self-motion of such matter may have begun, and the long reign of functional activity originated. This is all we find in functional life now, the self-motion of unstable colloids through the action of the energy set free by oxidation, and it is quite probable that such activity began as soon asa Konea colloid, of suitable constitution, was produced. But chemical evolution could not have ceased with this first appearance of functional action. It must have long continued, yield- ing products of higher and higher complexity, and more suscepti- ble to the function-produci ng influences, until finally the excessively mobile compound now called protoplasm originated. Yet there can be no doubt that with the earliest appearance of functional peti a check was placed upon chemical development. This . grew more vigorous as functional action became more unfolded. Finally a practical limit to the increase of chemical 1885.] The Relations of Mind and Matter. 535 integration was reached, and functional activity took its place, as the second great agent in evolution. Yet this check to chemism could have been by no means completed with the first appear- ance of active living forms. Superior and more susceptible pro- teids may have continued to appear, perhaps to the very borders ` of the present time, rendering the operation of functional change more and more active and capable. There is certainly good rea- son to believe that the protoplasmic basis of all beings is not identical, and if so, that chemical evolution may have continued, with ever-decreasing efficiency, throughout the whole long period of organic existence. As for the utter disappearance of the link forms between protoplasm and the highest existing inorganic compounds, it is no more surprising than the similar disappear- ance of so many of the link forms of life. They have been crowded out of existence by natural selection. Protoplasm doubtless has its embryology, whose steps, if we could trace them all, would lead us to a knowledge of its phylogeny. Many of the high-atomed products which successively appear in the development or during the disintegration and decay of organisms may be identical with primeval compounds which preceded proto- plasm. Yet all of these have their enemies in the vast and varied hosts of fungi which depend upon them for nutriment. They no sooner cease to be protected by the energies of active life, than they are assailed and partly reduced to simple inorganic condi- tions, partly become food for fungi. We can readily conceive, then, that were high-atomed chemical compounds now formed from the elements, by inorganic agency, they would in all probability be at once attacked by fungi, and © consumed as nutriment or disintegrated. The incessant activity of the fungoid organisms places a definite check on any high in- organic evolution under present conditions. Yet, as above said, in the existing. formation of protoplasm, its phylogeny is indi- cated precisely as the ancestral forms of the higher animals are indicated in their embryological development. Many of the steps may be slurred over in the one case as in the other, and in the formation of protoplasm by the plant, through successive inte- grations, from carbonic acid, water and ammonia, we may have a greatly shortened and masked preservation of the original steps of the development of protoplasm from the inorganic elements. The time may come when the human form can be phylogeneti- 536 The Relations of Mind and Matter. [June, cally traced, not only to the rhizopod, but to the chemical elements, The second great phase of material evolution, the functional, which has gradually unfolded until, from forms lower than the rhizopods—mere homogeneous masses of protoplasmic mole- cules—it has produced the extraordinarily intricate and hetero- geneous form of man, as the highest existing stage of material combination, is due to the operation of two characteristics inhe- rent in protoplasm. The first of these is the power of self-move- ment, through the agency of internal energy set free by oxida- tion. The second is the power of inducing new chemical action to the production of new protoplasm. The mode of operation ot this second agency is as yet in great part a mystery. But that it exists is too evident to be for a moment questioned. And there — is considerable reason to believe that these two agencies do not act simultaneously, but that oxidation of protoplasm and reinte- gration of the same are always successive processes in the organic economy. At some period in this long process of organic development there came into operation a third distinct phase or process of evolution, the psychical or mental phase. It is this with which we are here alone concerned. Its appearance and unfoldment seem related to functional action as the latter is to chemism. Psychical action has constantly tended to check functional varia- tion, and to replace it by a new controlling agency. As organic action slowly checked the development of chemism, and at last wholly or nearly superseded it, so psychical action has opposed the energy of functional variation and, in the case of man, has largely superseded it. The three modes of energy here indicated are probably all due to the action of forces inherent in the con- stitution of matter, and some of the conditions of this action are very evident. These it may not be amiss to briefly indicate. Every mass of matter, however composed, is constantly affected — by two sets of forces, those acting internally and tending to pre- serve and increase its complexity of organization, and those act- ing upon it from the external world and tending to reduce or destroy its complexity. In chemical integration the internal energy is in the ascendant. The compound is formed by the __ innate forces of its elements, and grows more complex through "See The Organic Function of Oxygen, AMER. NAT., Feb. and March, 1883. 1885.] The Relations of Mind and Matter. 537 the continued activity and supremacy of these forces. Yet all such compounds are constantly subject to the action of external forces, and are occasionally disintegrated or otherwise affected thereby. The more complex the compound the more exposed is it to the disturbing influence of external energy. At the same time the more complex the chemical compound, the less vigorous is the action of the innate energies of affinity. It is evident, therefore, that at some point a balance between these opposed energies must be reached. While chemical energies continue superior there must be a gradual increase in the complexity ot compounds, despite the assaults of external energy. But when these opposing energies become definitely equal in vigor, it seems evident that a fixed status must result. There may be upward and downward swings, as one or the other agency gains a tempo- rary supremacy, but the general level cannot permanently be departed from. Such is apparently the chemical status of protoplasm. It indi- cates the level of balance between internal and external energies. If it be broken down by a vigorous influx of external energy, the activity of chemical energy becomes superior, and reintegra- tion sets in until the balance of forces is again attained. Chem- ism cannot go further and produce a stable compound of higher complexity. Yet there is good reason to believe that unstable compounds of this high character are frequently produced, mole- cules lifted above the general level, and therefore liable to break = down instantly at the least influx of external energy. It is prob- ably to the existence of such excessively complex molecules that the high sensitiveness of nervous and muscular tissue is due. Lifted too far above the level of harmony of the forces, they break - down at a touch. Other results follow. Motor forces are set free within the tis- sue which give it self-motion. This self-motion brings it into new relations with external substances, and other changes than purely chemical ones follow. Variations in form and constitution in response to these external influences take place. Natural selec- tion upon function and form comes into play, and the organism that resists the adapting influence of external energy ceases to exist. Only those mobile organisms that readily yield to the molding influence of external energy, and closely adapt them- selves to the conditions of nature continue to exist. Thus in the ae 538 The Relations of Mind and Matter. [June, chemical phase of evolution internal energy is in the ascendant and controls the results. In the functional phase chemical energy merely holds its own, and a fixed molecular status is gained. But external energy acts upon tissue as a whole, and produces definite variations in form. If we now come to consider psychical evolution we find it still to be a question of the interplay of internal and external ener- gies. Reference here is made to its purely physical results, and not to its important characteristic of consciousness. In the growth of psychical conditions we still have to do with the exter- nal energies which play upon the body and force their way into it over the channels of the nerves. But as the body improves in its sensory organization, and permits the ready inflow of external energy, the balance between the two series of energies is broken, external energy becomes in excess and there is a tendency to break down the molecular complexity of the body to a lower level. Could all those inflowing energies play upon the muscles a fixed fall in the chemical level must succeed. As it is, however, these energies are checked in their inflow. The muscles are permitted to receive no more than they are prepared to accept. The remainder are restrained in their action to the cerebral gan- glion, where they exert an organizing influence upon some sub- stance whose character is as yet a problem. This is the third or psychical phase of organic evolution. The motor energies, thus drafted off into this cerebral sub- stance, there combine into a congeries of forces of yet unknown character, which we call the mind. It has two characteristics. The energies which constitute it are persistent. And they enter into new combinations which have no counterpart in external nature. It constitutes a new center of force which in its turn acts upon the body and aids in molding it. External forces are no longer supreme. A reservoir of internal energy has been formed which frequently acts in opposition to them. And one of the most essential characteristics of the action of this mental center of force is, that its activity is not exhausted upon the body. In fact it finds an important field of action in the external world. It molds nature as well as the body. In place of the organism _ needing to adapt itself to external conditions, it acts to adapt o external conditions to itself, and its own need of change is obvi- ated to the extent that it acts upon and remodels the world _ without. 1885.] The Relations of Mind and Matter. 539 All the numerous products made by man, his clothing, habita- tion, tools, &c., and all the changes in the conditions of nature produced by his agency, are results of this third phase of evolu- tion. Functional change is forced upon the external world, and to that extent ceases to act upon the body. Harmonious adapta- tion continues necessary, but nature is made to adapt itself to man, and man has little need to adapt himself to nature. It is not, however, a simple reaction, through the body, of external forces upon external nature. A reaction of this kind exists throughout organic life. Every motion of an organism in direct response to the impulse of external influence exerts an influence upon external nature. But asa rule it produces no new condi- tions. Adaptation is mainly confined to the body. In psychical action, however, new conditions are produced. The energies which have flowed into the cerebral reservoir are there recombined into new aggregates, or ideas, as we name them. These, in their reaction upon external nature, produce new conditions, embodi- ments in matter of new relations of energy, and the substances external to the body are forced to adapt themselves to the needs of the organism. This psychical reaction upon external nature is not a common characteristic of animal action. It is specially active in man, and presents a considerable activity in some of the lower tribes, as the beavers, the ants and the bees. But in the great majority of animals it is almost non-existent. Very few even of the higher vertebrates make any effort to adapt nature to their needs, but accept existing conditions. In such cases all the molding action of energies must be exerted upon their bodies, and such adapta- tion as becomes necessary must be confined to the organism. Yet psychical action in these lower animals is not without its special results, distinct from those yielded by the direct action of external energies, It yields rapid variations in the habits of the animal, adapted to particular cases, and which often enable it to survive where otherwise it would perish. These may be special movements in flight or combat, new modes of concealment, the display of cunning in non-habitual manners, and the like. In fact, in the difficulty of deciding whether any animal is influenced by mental energies or not, we are in great measure dependent on the occurrence of unusual actions, adapted to special situa- tions. If actions are habitual they may be unattended by con- 540 The Relations of Mind and Matter. [June, sciousness, even though they seem to display the utmost accuracy of reasoning. Natural selection yields results so closely analo- gous to those of reason that it is almost impossible to discrimi- nate between them, and in fact quite impossible except where a change of habits is displayed too great and sudden to be possibly due to the action of unconscious agencies on the slight congeni- tal variations in animal forms. In attempting to decide, then, at what level of life conscious- ness comes into definite existence, we are met with this difficulty. Actions of the most intricate character, such as many of those performed by the ants, for instance, are not beyond the conceiva- ble powers of natural selection if they have been for very many generations practiced, with extremely slow variations, by one species. Yet ants adapt nature to their needs, and thus counter- act the action of physical conditions upon their bodies. There- fore that phase of activity which we have above considered spe- cially significant of psychical agency—the remodeling of exter- nal conditions—seems to be not beyond the scope of natural selection, and only where the adaptation is individual instead of tribal, and rapid instead of gradual, can we be sure of its psychi- cal origin. If, for example, we consider the great kingdom of vegetable life, there are abundant reasons to believe that, in all of its higher manifestations, at least, it is devoid of consciousness. And yet its adaptations to the conditions of nature are often so complex and extraordinary that it seems almost incredible that they could have arisen without the aid of reason. Only the unpitying energy with which nature weeds out all illogical adaptations can explain the logical consistency of those that persist. If the habits of an animal change in response to logical reasoning, this change must be in the direction of exact adaptation to nature. But the same end is achieved by the blind but vigorous agency of selection, which is utterly merciless to the ill-adapted. If we could imagine plants to be suddenly given the power of motion, and thus brought into new and more varied relations to nature, it is evi- dent that their adaptations might become yet more intricate, and _ still more like the results of intelligence and judgment, though ~ gained through the action of unconscious influences, In such a n case s might readily rival many of the lower animals, and un- _ consciously perform actions closely analogous to those which it 1885.] The Relations of Mind and Matter. 541 is usual to ascribe to consciousness. In fact, the plant world is not utterly destitute of such motor powers. The mycelium of the Myxomycetes so closely simulates the Amcebze in its motions that it is difficult or impossible to distinguish it from the latter. Yet it is but a plant in motion, and is undoubtedly unconscious, Again the white blood corpuscles of animals are also indistin- guishable from Amoebz in character and habits; yet we can scarcely credit each of them with conscious life. Ata higher level in plant life we again meet with motor powers. Thus the carnivorous plants display characteristics not unlike those seen in the polyps; yet they are unquestionably unconscious, and we might safely ascribe a similar unconsciousness to the polyps and all other animals of similarly low grade. Thus if we begin at the lower levels of organic life, and trace nature upward in her development, it is very difficult to perceive where the influence of heredity and natural selection ceases to act and conscious choice enters into life as an element. On the other hand if we commence with the conscious life of man, and trace nature downwards, it is equally difficult to decide where consciousness ends. For at a certain intermediate level the phe- nomena observed might safely be ascribed to either conscious or unconscious action. Both seem capable of producing them, and it is utterly impossible to decide, with our present knowledge of the subject, which does produce them. Where there is evidence of unusual choice in some animal, or marked variation from its hereditary habits, we can be sure of conscious activity. On the other hand, where there is no nervous system, and no cerebral organ or force reservoir, we may reasonably question the exist- ence of psychical powers. And yet, even in this extreme case, we cannot positively declare that consciousness does not exist. In fact, although we may imagine that we are considering two conditions of whose actual existence we have equal knowledge, such is really not the case. Man finds in himself his only stand- ard of comparison. We know that within ourselves conscious- ness exists, and oversees, though it may not directly control, the great mass of our actions. We know, on the other hand, that many of our actions are performed unconsciously. In consider- ing the activities of lower nature, then, we cannot actually know that consciousness may not, to some extent, accompany them. We have some warrant to say that the unconscious action, which 542 Kitchen Garden Esculents of American Origin: [June, is exceptional with us, is the rule with them, but we can at no level positively declare, “ here it is absolutely impossible that con- sciousness should exist.” We must understand the subject far ‘more thoroughly than now ere this question can be definitely decided.

Jerusalem Artichoke-—Botanical analogies and the testimony of contemporaries agree, as we have seen, says De Candolle? in con- sidering this plant to be a native of the north-east of America. It was introduced to England about 1617, as we learn from the sec- ond edition of Gerarde? and this is nearly coincident with the first mention of this species in Europe, that by Fabio Colonna.‘ Lescarbot brought these roots into France about this time “ Hartichokes” are mentioned as growing in Virginia in 1648,° and “ artichokes ” were cultivated at Mobile in. 1 775, but whether this plant or not, does not appear from the context” They are mentioned by writers on American gardening from 1806 onward’ In Pennsylvania the tubers are yet raised by some and sent to the New York market, “they are disposed of for lunch purposes and there is a ready sale.” Most interesting articles on the geographical and botanical his- tory of this plant, by Messrs.

The former was first known in Europe in 1738, the latter, a South American species, not until 1824.1 M. craniolaria Glox., the white flowered, has appeared by name in one at least of our seed catalogues among garden vegetables. It was described in 1785. M. violacea Engelm. occurs in the South- western States, and the Apache Indians gather the half ripe seed pods to be used for food. The Martynia was not an inmate of our kitchen gardens in 1828, not being mentioned in Thorburn’s seed catalogue of that date, nor in Noisette’s Manual du Jardinier, It is not mentioned for American gardens by Schenck in 1854, but is by Burr in 1863.4 It hence may be considered as of recent introduction. Nasturtium—Tropeolum majus L. and T. minus L., find place in our seed catalogues for use as a garnish and salad, and the unripe seed pods for salads and pickling. Both are natives of Peru. The former came to Europe in 1684, according to Linnzus,’ or 1686, according to Noisette’ and according to Collinson’s manu- scripts it reached England in 1686. The dwarf nasturtium was known at Lima in 1580 by Dodonzus, was cultivated in England by Gerarde in 1596, and was a great favorite with Park- inson in 1629; it was then lost, but afterwards reintroduced Miller, in 1768, says it was then only less common than the tall. Both the tall and the dwarf were in French kitchen gardens in 1828,° but the tall seems to have then only reached our ‘culture, as the dwarf is not mentioned in Thorburn’s seed catalogue of 1828. The tall is mentioned by M’Mahon as in American gar- dens in 1806, by Gardiner and Hepburn in 1818, and the tall and dwarf by Bridgeman in 1832. Both were grown in = gar- dens in 1778.2. One common name, “ Indian cress,” used as late as 1854 by writers on American gardening, would suggest that the use as a vegetable was coincident with its second introduc- tion, as Parkinson’s fondness for it would seem to imply. 1 Noisette.

[June, The nasturtiums have received greater welcome in our flower gardens than for table use, and a large number of varieties have been developed as florists’ plants. Peppers—There seems to be now scarcely a doubt as to the American origin of the peppers, Capsicum sp. It seems, how- ever, to have escaped the attention that it deserves, that the large number of forms already developed at the time of the discovery of America is indicative of a long cultivation, and adds testimony to the agricultural habits of the people. A vernacular name, especially if short, is very persistent in its horticultural use, and in. those varieties of vegetables which are grown in kitchen gar- dens, some names alone, without descriptive text, may be as- sumed as indicative of the existence of a variety to which the same name is applied to-day. Such investigations as we have made indicate that this is especially true for the peppers. ow many species there are of peppers I cannot make out. Many described species can be urhesitatingly referred to Capsi- cum annuum, a species of great variability, and which seems to be a perennial in some regions, as in F lorida, as I am informed, and in Chili, according to Molina. We shall make use of the specific names as we find them. According to Bancroft! the use of peppers by the Southern natives was as great in ancient times as is now observed. Saha- grun? mentions chili more frequently than any other herb among the edible dishes of the Aztecs; Veytia® says the Olmecs raised chili before the time of the Toltecs. “ ft is the principal sauce and the only spice of the Indians” as Acosta writes in I 578, and Schomburgh says that the present Indians of Guiana eat the fruit of these plants in such abundance as would not be credited by an European unless he were to see it. Columbus carried peppers with him on his return voyage in 1493, and Peter Mar- tyr, in his epistle dated September, 1493, Says it was “more pun- gent than that from Caucasus.” In 1494 a letter written by Chanca, physician to the fleet of Columbus on his second voyage, to the Chapter of Seville, refers to its use as a condiment. Cap- sicum and its uses are more particularly described by Oviedo, 1 Native Races, 11. ? Hist. Gen., 11, lib. vir. 1885. ] Kitchen Garden Esculents of American Origin. 545 who reached tropical America from Spain in 1514. Clusius asserts the plant was brought from Pernambuco by the Portuguese to India, and he saw it cultivated in Moravia, in 1585." Hans Stade,” during his captivity in Eastern Brazil, about 1550, says the “ pepper of the country is-of two kinds; the one yellow the other red; both, however, grow in like manner. When green it is as large as the haws that grow on hawthorns. It isa small shrub about half a fathom high, and has several leaves: it is full of peppers which burn the mouth.” G. de Vega,’ writing of Peru in 1609, says the most common pepper is “thick, some- what long, and without a point. This is called ‘ rocot uchu’ or ‘thick pepper,’ to distinguish it from the next kind. They eat it green, and before it assumes its ripe color, which is red. There are others yellow, and others brown, though in Spain only the red kind has been seen. There is another kind, the length of a geme (5 inches ?), a little more or less, and the thickness of the little finger. These were considered a nobler kind, and were reserved for the use of the royal family. * * * * Another kind of pepper is small and round, exactly like a cherry with its stalk. They call it ‘chinchi uchu; and it burns far more than the others. It is grown in small quantities, and for that reason is the more highly esteemed.” Cieza de Leon, who traveled in Peru, 1532-50, speaks of the Capsicum as a favorite condiment of the Peruvian Indians. Molina’ says many spe- cies of Capsicum called by the Indians “żhapi” are cultivated in Chili, among others the annual, which is there perennial, the berry pimento and the pimento with a subligneous stalk. Wafer, 1699,° says on the isthmus they have two sorts of pepper, the one called de// pepper, the other dird pepper, and great quantities of each are much used by the Indians.” Each sort grows on a weed or shrubby bush about a yard high. The bird pepper has the smaller leaf, and it is by the Indians better esteemed than the other.” Ligon, 1647-53,’ also mentions two sorts in Barbadoes, “the one so like a child’s corall as not to be 1 Pharmacog., 406. 2 Hak.

Those which are most commonly noticed are the de// pepper, goat, bonnet, bird, olive, hen, barbary, finger, cherry, &c. Of these the ġel is esteemed most proper for pickling.” Capsicum annuum L., has never been found wild, but C. frutes- cens Willd. has been found wild, apparently indigenous, in South America. De Martius brought it from the banks of the Amazon, Poeppig from the province of Maynas in Peru, and Blanchet from the province of Bahia? The form, C. indicum Rumph. = C. fru- tescens L., is said by Ainslie? to be constantly found in a wild state in the islands of the Eastern archipelago. Capsicum annuum L.—According to Naudin C. longum DC., and C. grossum Willd., are not specifically distinct from this plant. It is said by Clusius to have been brought by the Portuguese from Brazil to India, and reached England in 1 548 > and is men- tioned by Gerarde as being under cultivation in his time. The fruit is variable in form and color, as is also the plant.

Bird pepper is mentioned by name by Long in Jamaica, and by Wafer for the Isthmus ; is perhaps the pepper “as large as haws” described in Brazil by Hans Stade. It has been in England since 1731,? and a “ dird or West Indian” was in American gardens preceding 1828. It is mentioned as well known in India by Firminger and Drury, but I do not identify it with any of the present varieties of our seed catalogues. From an uncertain authority? it is said to grow wild from Southern Texas to Arizona, but it is not catalogued in the report on the plants of the “United States and Mexican Boundary Survey,” 1858, unless it be synonymous with C. microphyllum Dun. C. cerasiforme Mill.—Cherry pepper, also described by Tourne- fort, 1700, It was sent from the West Indies. It is probably one of the sorts described for Peru by Garcilasso de la Vega under the name chinchi uchu. It is also among the names listed by Long for Jamaica, and was in American gardens in 1806 or before. It is a variety of C. annuum, and the fruit is quite varia- ble in form and color, some sorts being yellow. The form figured in Hortus Eystellensis, 1613, is precisely the cherry pepper of our gardens, C. conoides Mill—Came to Miller from Antigua cites the name of hen pepper. This isa name which appears in Long’s list of Jamaica sorts. The description of the fruit would answer to that of the oxheart of some of our seed catalogues. C. cordiforme Mill., or heart-shaped Guinea pepper, was also described by Tournefort, 1700.4 It has several varieties, the 1 Miller’s Dict. ? Booth, Treas. of Bot.

It can be referred to C. annuum, and seems to be the oxheart of some of our seedsmen. C. fastigiatum Blume, syn. C. minimum Roxb.—lIt is the C. Jrutescens L. Spec. Plant., but not of L. Hort. Clif., to which the name C. frutescens is usually applied. It occurs abundantly wild in Southern India, and is extensively cultivated in tropical Africa and America? According to Miller it is C. indicum Rumph. (Amboyna), and the Cafo-molago of Reede (Malabar) which fixes its presence in the East Indies about 1700. It is described by Loureiro, and was in England in 1656. It does not appear to be among the species grown in American gardens, all of which can be referred to C. annuum. C. frutescens: L.— This has been called barbary, cayenne, shrubby and goat pepper. It seems to have occurred in our seed catalogues under the name of True Cayenne, but does not appear to be cultivated with us now. It was in English gardens in 1656.° and seems to have been called daréary from the size and shape of its fruit, which are like those of a berberry. It seems to be culti- vated and to have native names in Hayti, Peru, Mexico, India, Burma, Malabar, Ceylon, Yemen, Greece, Egypt, &c., and fur- nishes much pod pepper to commerce. It has been found wild from Bahia to Eastern Peru in tropical America In Ceylona red, a yellow and a black fruited form are known C. grossum Willd.—This is the pepper with large sweet square fruits, and furnishes many varieties and synonyms to our seed catalogues, and is considered to be but a form of C. annuum. It may be the ocot uchu of G. de Vega. It was, according to Mil- ler’s Dictionary, described by Besleri in 1613, by Bauhin in 1671, and by Tournefort in 1700. C. tetragonum is a synonym by Miller, 1737. It was cultivated by Miller in 1759. Accord- ing to Noisette’ it reached Europe in 1548. It is called in Hin- dustani Zaf/rie-murich, and the fruit, as large as a small apple, is called by the English in India coffrie chili’ or, according to Fir- - 1 Pharmacog., 452. ih.

There are red and yellow sorts, as in most of the so-called species. This is perhaps the de// of Long’s Jamaica list, as he says it is esteemed most proper for pickling. C. longum DC. is another form usually referred to C. annuum. It reached Europe in 1548, or before,’ and would appear to be the second kind, so much esteemed, of De Vega, and the one of the sorts referred to by Ligon as “resembling a child’s corall.” Corail. is yet one of the names for this sort in France. It was grown in England in 1597 and before, as Gerarde speaks of it. There is a figure of it in Fuchsius’ Historia Stirpum, Basle, 1542, under the name of siliquastrum or calicut pepper, and a state- ment that the plant had been introduced into Germany from India a few years previously. It was in American gardens, by name at least, before 1806, and is the Zong red or long yellow of our present seed catalogues. C. microphyllum Dun. is said by Torrey to occur in Western | Mexico, Chihuahua, Nuevo Leon, etc., but he does not say whether cultivated or wild.

The name appears in Long’s list, edition of 1774. C. tetragonum Mill., 1737, is referred by him to C. annuum L., and also to C. grossum L., to which latter form it appears to rightly belong. It is now cultivated under the name of paprika in ower Hungary ona large scale, the fruit three and a half to five inches long and three-quarters to one inch in diameter! As this is a sweet variety, it is probably C. grossum, which is a form with very variable fruit. The name Jdonnet pepper is used by Miller, 1743, for C. angulosum, as already stated. C. violaceum Humb. is apparently a variety of C. annuum, but the plant more or less deeply violet-tinted, the fruit black-violet on one side and reddish-green on the other, but becoming. red in ripening. It came from Spanish America, and is now an occa- sional inmate of our gardens. The twenty-two named varieties grown during 1882 and 1883 at the New York Agricultural Experiment Station seem to belong to C. annuum L., and while we are not prepared to affirm that they all can be identified with one or the other of the above named species, yet we think there is probable identification suffi- cient to justify the conclusion that no strongly marked sorts have appeared during the five centuries of European culture. When we consider that the various kinds of peppers easily cross-fertil- ize, and hence the difficulty of keeping the sorts distinct, we are led to believe that many of the forms which have received spe- cific description are true agricultural or form-species, sufficiently distinct at their first appearance by discovery to justify a conclu- sion as to a long antiquity, and as to their power of resisting change. The whole genus needs revision from an agricultural instead of a strictly botanical standpoint. Potato—De Candolle in his Origin of Cultivated Plants, says truly: “No one can doubt that the potato is of American ori- gin.” There are some interesting notes, however, which De Candolle has not used. Prescott in his Conquest of Peru? says in 1526 Pizarro, at the Rio de San Juan, eat the potato as it grew without cultivation, This evidence is as conclusive as to its wild _ State as the one which De Candolle quotes from Gray, which _ “sufficiently proves its wild state in Chili, viz., that even among the Araucanians, in the mountains of Malvarco, the soldiers of 1 Gard, Chron., Sept. 10, 1881,343. 71, 248, 1885.] Kitchen Garden Esculents of American Origin. 551 Pincheira used to go and seek it for food.’ Prescott adds, on the authority of Xerez,? that along the coast of Peru he saw the hill- sides covered with the potato in cultivation. Pedro de Cieza de Leon, who traveled in Peru, 1532-5, says that the principal food of the Collao was potatoes, which “are like earth nuts.’ John Hawkins, in his second voyage, 1564, says the potatoes at Margarita island, “be the most delicate rootes that may be eaten, and doe far exceede their parsenips or carets,”* which, if sweet potatoes be not meant, indicate their introduction to the island, as the context parsenips and carets shows. Captains Preston and Sommers, 1595, my. at Dominica island “the Indians came unto us in canoes * “iti and brought in them plantains, pinos and potatoes,” which indicates how potatoes and other victuals were taken aboard ships as pro- visions. Under the name openawk Heriot describes, in 1584, what is supposed to be the potato in Virginia, and of which De Candolle thinks there can be no doubt. This fact would seem to indicate that potatoes in our quotation meant potato and not the sweet potato, It is quite probable that Hawkins carried the first potatoes to Virginia, for in 1565, after relieving the famine among the French on the banks of the River May (St. Johns), he sailed northward toward Virginia, which name included the Carolinas and a large extent of coast at this time, and had this tuber aboard as he brought tubers from Santa Fé de Bogota on this voyage into Ireland, as has been currently stated, and we know not upon what evidence Miller and Sir J. Banks believes these tubers to have been the sweet potato. What renders the opposite view more tenable is the course that ships customarily sailed, this being to Virginia by the way of the West Indies; and as well by the fact that Virginia received the potato from the beginning of its settlement. It is mentioned by Heriot, 1584, as already stated ; is noticed there again in 1609, in 1648,’ and again in 1649 under circumstances that can leave no doubt: “The West India pota- toe (by much more delicate and large than we have here grow- 1 Flora Chiliena, v, 74. 2 Conq. del Peru ap.

[June, ing) besides that it is a food excellently delicious and strongly nourishing, fixes himself wherever planted, with such an irradi- cable fertility, that being set it eternally grows.”! We see here the distinction drawn clearly between the sweet potato described and the potato already under cultivation. The argument that if the introduction by Hawkins into Ireland had been the potato, it would have secured dissemination, loses its force when we consider the slowness of its progress in Eng- land. It was certainly grown by Gerarde in 1597. In 1663 Mr, Buckland, of Somersetshire, drew the attention of the Royal Society to its value, earnestly recommending the general cultiva- tion of the potato throughout the kingdom. In 1664 Forster recommends its cultivation in England. Ray, 1686, takes no further notice of the potato except by saying it is dressed in the same manner as Spanish batatas; Merritt, 1687, records that potatoes were then grown in many fields in Wales ; Worlidge, 1687, describes potatoes as being very useful as “ forcing fruits,” and does not hear that field culture has yet been tried; Lisle, a little later, is wholly silent about the potato, as are also London and Wise, 1719; Mortimer, 1708, says the potato is not as good nor as wholesome as the Jerusalem artichoke, but that it may prove good for swine; Bradley, about 1 719, says they are of less note than horse-radish, radish scorzoners, beets and skirrets, but as they are not without their admirers, he will not pass them by in silence. Other authorities to the same purport are given in Martyns Miller’s Dictionary. Worlidge above quoted, and Clusius says that the plant had be- come so common in Italy that it was eaten like a turnip and - given to the pigs. Targioni does not, however, recognize this former wide cultivation in Italy, and says that it was only at the end of the sixteenth century or beginning of the seventeenth that the cultivation became known in Tuscany. In support of the ae theory that the potato was not as palatable in early times as now, -\ 2° SViteinia by E. W i i -— 10a. wont T Gent., Lond., 1650, 48. 1885.] Notes on the Labrador Eskimo, etc. 553 we may quote a few authorities. Miller, in 1754, says they were despised by the rich and deemed only the proper food for the meaner sort of persons. Mawe and Abercrombie, 1778, give caution as to their deleterious properties unless thoroughly well cooked. In 1830, in Watson’s Annals of Philadelphia, it is writ- ten that a gentleman, “now in his goth year, told me that the potatoes used in his early life were very inferior to the present. They were called Spanish potatoes, and were very sharp and pungent in the throat and smell. They send occasionally a bet- ter sort from Liverpool.” In 1698 potatoes were scarce, Jerusa- lem artichokes abundant, in French markets. Were a new root equal in edible quality to our snowflake potato and of the same ease of culture, now introduced, who can doubt its quick recognition and adoption? It would not be compared to the parsnip or carrot, as Hawkins did his potato, but would be described in glowing terms. We would not have its medicinal qualities under discussion, but would be satisfied to have it on our tables. If, however, we should now eat some of our poorer qualities of potato, such as were commonly grown for cattle a quarter of a century ago, we would see in the soggy and hard condition a root which might well have excited the admira- tion of Hawkins, and which would have suggested the parsnip or the carrot for comparison more than would a sweet potato. (To be continued.) 10: NOTES ON THE LABRADOR ESKIMO AND THEIR FORMER RANGE SOUTHWARD. BY A. S. PACKARD, (Continued from p. 481, May number.) To stone structures, particularly the grave or dolmen-like burial places referred to by the Moravians, are of course mat- ters of very great interest. In connection with that statement we would draw attention to the following extract from “The three voyages of Martin Frobisher,” second voyage, 1577, Hakluyt Society, London, 1867, p. 136: “In one of the small islands here [near Lecester’s Iland in Beares sound] we founde a tombe, wherein the bones of a dead man lay together, and our savage being with us and demanded (by signes) whether his countryman had not slain this man and eat 554 Notes on the Labrador Eskimo [June, his flesh so from the bones, he made signes to the contrarie, and that he was slain with wolves and wild beastes.” Although it is generally stated that the Eskimo seldom if ever bury their dead, the foregoing statement would show that in early times at least they took pains to place the corpse in stone tombs. I found at Hopedale, in 1864, two skeletons, evidently Eskimo, interred in the following manner: while walking over a high bare hill north-east of the station I discovered a pole projecting from what seemed a fissure in the rock; it proved to be the sign of an Eskimo grave; the pole projected from the chasm, which was about fifteen inches wide and twenty or twenty-four inches in depth; the opening was covered by a few large stones laid across the fissure. At the bottom lay the remains of two skeletons en- tirely exposed to the elements, with no soil over them. The skulls were tolerably well preserved, and so were the Jong bones, but the vertebre, ribs, &c., had mostly decayed. Judging by the way in which such objects are preserved in the open air on this coast, the burial must have been made at least over half a century ago, but more probably from one to three centuries since. We now glean the following extracts from Hind’s excellent Ex- plorations in the Interior of the Labrador peninsula, which show that the Eskimo spread south-westward along the coast of Lab- rador as far as the Mingan islands. Speaking of the Montagnais or coast Indians of Labrador, he writes: “ Of their wars with the Mohawks to the west, and the Esquimaux to the east, between 200 and 300 years ago, there not only remain traditions, but the names of many places in the Lab- rador peninsula are derived from bloody battles with their bold and aie enemies, or the stolid and progressive Esquimaux = (1, p. ii -Fhe sinkinit of the Great Boule, 700 feet above the sea, and the brow of the bold peninsula on the west side of the harbour [Seven Island bay] were two noted outlooks in the good old Montagnais times. They are not unfrequently visited now, when the Indians of the coast wish to show their country tothe Nas- quapees from the interior, and to tell them of their ancient wars _with the Esquimaux. * * * They were able to hold their own against the Esquimaux in consequence of the almost exclu- oe sively maritime habits of the people, who rarely ascended the rivers further than the first falls or rapids: and they fearlessly 1885.] and their former range Southward, 555 pursued their way through the interior of the country as far as the Straits of Belle Isle and Hamilton inlet, but exercising the utmost caution as they approached the sea to hunt for seals” (p. 30). Of the Mingan islands Esquimaux island was so named “ be- cause the Esquimaux were wont to assemble there every spring in search of seals,” &c., &c. (p. 49). “ The ruins of Brest must not be confounded with those of the old Esquimaux fort some distance farther up the straits, and which are found on Esquimaux island in St. Paul’s bay. These ruins, consisting of walls composed of stone and turf, remain almost entire to this day ;! and on the same island are large num- bers of human bones, the relics of a great battle between the Montagnais and French on one side and the Esquimaux on the other, which were found about 1840” (p. 130). “At Fox harbour there is a small settlement of Esquimaux, who are now orderly and industrious Christian people, fruits of the faithful labours of the missionary at Battle harbour, who has resided eight years on the coast” (p. 198). “Seals have been the chief cause of the wars between the Montagnais and Esquimaux of the Labrador peninsula, and most of the conflicts between these people have taken place at the estuaries of rivers known to be favourite haunts of the seal” (p. 204). Regarding the Eskimo living near Caribou island, at the mouth of Esquimaux river, Strait of Belle Isle, in 1860 and several years after that date, the following information has been kindly given me by the Rev. C. C. Carpenter, for some years (1858 to 1865) a missionary to this part of the Labrador coast: “ Concerning the Esquimaux (‘ Huskemaw,’ old father Chalker at Salmon bay used to call them), in my time there was only one family living in the immediate vicinity of the mission, and that only a fragment—the Dukes family. They once lived at the extremity of Five League point. The husband (George?) died and the wife married an Englishman, old Johnny Goddard. She was a full-blooded Esqui- maux, and could kill a seal by imitating its appearance in dress and cry, just as quick as the next man, and a good deal quicker if the other was white! She died at a great age about the year 1879. I was on the coast, after an absence of fifteen years, in 1 Robertson of Sparr point. - 556 . Notes on the Labrador Eskimo [June, 1880, and was told that she was about 100 years old, but I deemed that an exaggeration. Her sons were George and An- drew, both now dead of consumption. I-buried George at Mid- dle bay in 1862. Andrew died since we came away. He had visited Halifax and had had his photograph taken ; I havea copy of it; it is, however, of a dressed-up man, not my old Esqui- maux friend. Both of the sons were unmarried. A daughter of old Aunt Jenny Goddard had a daughter, I think by an American sailor, She was called Lucy Dukes, and (her mother dying) was adopted by Mrs. Goddard, I dare say you remember her there at Stick Point island; she was lame. She married little Johnny Goddard, nephew of old John, and they with several children occupy the island home. She said to me in 1880, ‘“ There’s my Jenny, just look at her narrow features ; you know Granny had a very narrow face!” And yet an old sailor once said that the old woman’s face was as flat as a barn door! “There was another family of Esquimaux, whose residence was at St. Augustine; I cannot recall the surname. I used to sec one, ‘ Louis the Esquimaux.’ My impression is that one only of that family was living in 1880, for I brought home Esquimaux dolls in full dress made by her. These I feel sure were all the remnants living in my parish, say tor fifty or a hundred miles up and down the coast. “The Esquimaux in Southern Labrador are a remnant. Once powerful there and numerous, they were defeated in a battle fought on Esquimaux island (at the mouth of the river) by the Indians (Mountaineers), and what few were left went northward.” We observed on Caribou island traces of Eskimo occupation in the form of a circle of stones, like that observed farther north near Strawberry harbor, Along the coast north of Hamilton inlet are a few Eskimo, half-breeds and probably remnants, At Roger’s harbor we took aboard as pilot to Strawberry harbor one Cole, a half breed, part Eskimo and part Englishman, who had an Eskimo wife and two three-quarters-breed children ; his mother was an Eskimo, There _were formerly a few Eskimo living in this region, but they had died off rapidly within a few years past; our pilot from the / States, Capt.

Their disappearance seems due partly to that of + 1885.] and their former range Southward. 557 seal, fish, birds and other game, and partly to contact with the civilization of this coast, their close winter houses inducing con- sumption and other chest troubles; but whatever the causes, the race is rapidly fading away, going by entire families. Cole was intelligent and could read and write. On our way to Strawberry harbor we were boarded by an Es- kimo who paddled up to our vessel in his kayak. He had been living in the bay during the summer. The next day I landed on a little flat islet near our harbor, and found traces of recent Eskimo occupation. An Eskimo family had evidently been sum- mering there in a seal-skin tent. The marks of their temporary sojourn were the circle of water-worn stones which had been used to pitch the tent, the feathers and bones of sea-fowl which had been shot or snared, scattered bones of the seal and other unmistakable signs of Eskimo occupancy and of Eskimo personal uncleanliness. While here we learned that some Eskimo were spending the summer on an island hard by, and we tried to find one to pilot us to Hopedale, but were unsuccessful. We, how- ever, obtained one who had received some education and was then living ten miles up the bay with a Norwegian in the employ of the Hudson Bay company, his pay being fifty dollars a year. The number of Eskimo on the Labrador penisula is estimated at 1400, but this is probably an overestimate, as most of this race are now partly civilized and gathered at the Moravian Mission stations of Hopedale, Nain, Okkak, Zoar and Ramah. At the time I visited Hopedale, which was in the summer of 1864, in the expedition of Mr. William Bradford, the well known artist, the Eskimo population of that station was about 200. It was reported to us that during the preceding March twenty-four Eskimo had died of “colds ;” while at Okkak twenty-one had died, and the same number at Nain. Thus over a tenth part of the native population at these stations had died of chest diseases in a single month. This high death rate may be the result of their partial civilization and less hardy out-of-door life, but their houses are not very different from those their savage ancestors inhabited. The missionaries have wisely not attempted to force upon them European standards of living as regards dress and houses, and their system of trading with them as well as teaching them does not appear to have been accountable for this rapid de- crease. On the contrary, anthropologists as well as humanita- 558 Notes on the Labrador Eskimo [June, rians are under obligations for the success these devoted Mora- vians have had in preserving on American soil this interesting people intact, unmixed, and with some of their harmless and more interesting habits preserved. They are, however, doomed, judg- ing by the past years’ experience, to ultimate extinction. As regards the longevity of these people, we understood the oldest person at Hopedale, the patriarch of the colony, to be a woman of seventy years; we saw her, a picture of uglinesss which still haunts our memory. There were three Eskimo who were sixty years old. A man becomes prematurely old when forty-five years of age, as the hunters are by that time worn out by the hardships of the autumnal seal fishery. The Eskimo settlement of Hopedale, the only one we visited, was founded in 1782. It consisted in 1864 of about thirty-five houses, arranged with more or less disorder in three principal streets. They are mostly built of upright spruce logs with the bark still on, dovetailed at the corners and banked nearly to the eaves with turf on the outside; the roof rather flat, though irregu- lar, with a skylight and small window in one side, either as in the case of the more well-to-do families consisting of a rude sash with four or six glass panes, or panes of the intestines of the seal sewed together. The house is entered through a long low porch, probably the survival of an ancient style, z. e., the low porch of their snow houses through which their forefathers crept on their hands and knees. On entering we were obliged to stoop low and to circum- spectly make our way between the carcass of a seal or a codfish, as the case might be, and a vessel of familiar, democratic shape and use, filled with urine, in which the sealskins are soaked before being chewed between the teeth of the housewife, an important step in the process of making or mending sealskin boots; while Eskimo dogs of various sizes and colors blocked the devious way. i Across the end of the interior, which was floored with wood, and in which we could not stand erect, was a wooden bed or seat, a sort of divan, on which sat a woman in spectacles weaving a basket of dried rushes which had been colored blue or red; ~ she nodded a welcome and made us feel quite at home. The other beleogisgr of the house were a hearth or fire-place of a few pebbles sii on one side, a soapstone lamp which was a 1885. ] and their former range Southward. 559 flat oblong dish, carved out of soapstone, of normal Eskimo design ; some knives of European manufacture, needles and thread, while on a shelf we noticed an Eskimo Bible with the owner’s name written in a neat hand on the fly leaf. On the whole the interior was neater and less offensive to the eye and nostril than we ex- pected, as was the exterior. Besides the house, on a cross-pole supported by two uprights, rested a kayak, and over another hori- zontal pole hung drying a black bear’s skin or dried cod-fish, as the case might be. The spaces between the houses were rudely drained, and saving the usual refuse heap at the rear of the house, a dog’s carcass, fish bones and other rejectamenta, there was nothing particularly repulsive, though certainly nothing attractive about the houses. Two families sometimes live in the same house, which is partitioned off simply by a low rail passing through the middle. We do not remember seeing any babies, and there seemed to be few children compared to the adults; here as in the arctic regions the Eskimo having small families. The women’s dress differs from that of the Greenland Eskimo in the much longer tails of their jackets, which as seen in Pl. xvir nearly reach to the ground; by the Greenlanders it is worn but little longer than the men’s; this difference, as seen on p. 473, was remarked by Cranch. Of late years woolen goods have partly superseded sealskin, but the pattern has been retained. Another difference is the form of the kayak; that of the Labra- dor Eskimo is much broader than the Greenland kayak, and of clumsier build, since the frame of the former is made of spruce ; this renders the Labrador kayak perhaps safer. So far as we could see the Labrador Eskimo at and north of Hopedale are full-blooded. Our engraving (Pl. xvi1) is from a photograph taken by Mr. Bradford, and gives an excellent idea of a Hopedale Eskimo couple with their baby. The faces apparently show no trace of foreign blood, while there is said to be not a full- blooded Eskimo in the Greenland colony, the intermixture with the Danes and Scandinavians in general being thoroughgoing. Few Europeans or Americans had previous to 1864 visited the Labrador coast north of Hopedale, and there the race has been preserved in most cases intact, though there may now be an occa- sional intermixture with the Newfoundland fishermen, who now go as far as Nain. __ As to the number and distribution of the Eskimo north of the 560 The Inter-Relationships of Arthropods. [June, Moravian stations, we now have some definite information from Lieut. Gordon’s report of the Hudson’s Bay expedition of 1884. He says: “I cannot help thinking that their numbers have sensi- bly diminished, inasmuch as we found signs of their presence everywhere; yet except at Port Burwell, Ashe inlet and Stupart’s bay, none were met with. About six miles south of Port Bur- well [Cape Chudleigh} there are the remains of what must once have been a large Eskimo settlement, their subterranean dwell- ings being still in a fair state of preservation. At the present time, so far as I can learn, there are only some five or six Eskimo families between Cape Chudleigh and Nachvak. ‘ Along the Labrador coast the Eskimo gather in small settle- ments round the Moravian Mission stations; at these places their numbers vary considerably. Nain is reported to be the largest settlement, and its Eskimo population amounts to about 200 souls ” (p. 16). :0: THE INTER-RELATIONSHIPS OF ARTHROPODS. BY J. S. KINGSLEY. es most of the schemes of classification in vogue to-day the Arthropods are divided into two groups of equal rank, the first being the Crustacea, the second embracing the Tracheata or Insecta. Having recently studied the embryology of Limulus, and finding it necessary to ascertain its place among the arthro- pods, the writer was led to compare, in a critical manner, the various groups. This led to somewhat unexpected views as to the various inter-relationships of the different “types” (if that word may be pardoned), and as the results may prove of interest, a short résumé is here presented in advance of the full article which will appear in the Quarterly Journal of Microscopical Sci- ence for October. . It might be stated here, parenthetically, that upon a large num- ber of points regarding the arthropods, and especially the so- called tracheates, our knowledge is extremely deficient. For this reason some of the following account is merely tentative, the probability being in favor of the views here adopted. _ First, we may take up the relationship of Limulus to the spiders. s The view first suggested by Strauss-Dürckheim and lately so ably o supported by Professor E. Ray Lankester, that Limulus is not a crustacean but an arachnid, receives full confirmation from the 1885.] The Inter-Relationships of Arthropods. 561 development of the king-crab. The introduction of this form into this group seems to necessitate a new term for the whole, and I have adopted the name Acerata for the arachnids and the merostomes, in reference to the absence of antennz. It is but a slight modification of the word Acera, used many years ago by Latreille for the spiders alone. The term Arachnida still retains its former significance. As here limited, the Acerata may be defined as arthropodous animals with the body divided into two regions (cephalothorax and abdomen), the cephalothorax bearing six pairs of primitively post-oral appendages. The number of abdominal appendages vary, but four or more are modified for respiratory purposes ; respiration being performed by gills, “lungs” or trachez, the homology between these three types of organs being easily traced. The genital ducts empty at the base of the seventh (first abdom- inal) appendages and paired segmental organs open, in the young, at the base of the fifth pair of limbs, but lose their excretory duct in the adult. The genital glands are branched and the branches communicate through numerous anastomoses. The liver is large and voluminous. The development is direct, no metamorphosis being introduced. Some of these points may require explanation, and while I would refer the reader to the paper on the embryology of Limu- lus for details, I may here mention a few facts. My studies on the development of the gills of the king-crab when compared with those of Metschnikoff on the scorpion and those of Salen- sky on the spiders, show that the lungs of the one and the gills of the other are (as was suggested by Lankester) perfectly homologous. They arise as foldings at the base of appendages, occupying the same position serially in both Limulus and the scorpions. Leydig showed, some thirty years ago, that the tracheze and pulmonary sacs of the spiders were homologous organs, and in later years the same has been pointed out by Bert- kau and Macleod. One very important point should here be noted. In the spiders the stigmata or external openings of the trachez or pulmonary sacs never occur elsewhere than on the abdomen, and they always perforate the sternal plates. In the hexapods they occur in all parts of the body, and always on the sides and never on the ventral surface. The so-called coxal glands or, as I regard them, segmental 562 The Inter-Relationships of Arthropods. [June, organs, have only recently been known. Packard first found them in Limulus, and later Lankester made an exhaustive histo- logical study of them in comparison with similar glands occur- ring in the scorpions. Neither of these authors were able to find any external duct. More recently Bertkau has found that in the young spider they open externally at the base of the fifth pair of appendages (third pair of legs), but this duct is lost in the adult. The studies of Mr. Michael on the coxal glands of mites are, so far as they go, confirmative. In Limulus I found that they arose as coiled mesoblastic tubes, closely comparable to the segmental organs of worms, and emptied in the young at exactly the same point as in spiders. It seems to me that these various points show that the Acerata are more closely allied to the Crustacea than to the hexapods and myriapods with which they are usually classed. Lankester has shown from a study of Apus that all of the crustacean appen- dages are primitively post-oral, a fact which is confirmed by the study of the development of various forms. With this point set- tled it would appear that we have a perfect right to compare, within certain limits, the segments and their appendages of spi- ders and crustaceans. Tabularly arranged, the result would be somewhat as follows : CRUSTACEA. ACERATA. 1, Antennula, Chelicera, II. Antenna Pedipalpus tt. Mandible, Leg 1. Iv. Maxilla 1. Leg It. v. Maxilla 2. Leg 111. vi. Maxilliped 1, Leg Iv. That this serial comparison is legitimate is shown by several reasons besides that given above. In the Acerata the series em- braces all of the cephalothoracic appendages. In the Crustacea it stops exactly at the line of division between the so-called head and thorax of the tetradecapods as well as in the embryos of many other forms. A further point is interesting. In many of the lower Crustacea a pair of so-called shell glands occur which are regarded by Claus, Grobben and others as comparable to the segmental organs of worms. The outlets of these organs occur -~ at the bases of the second pair of maxillz, a position which the ~ ~ above table will show is exactly comparable to that of the outlet __ of the coxal glands of Limulus and the spiders. In many Crus- 1885.] The Inter-Relationships of Arthropods. 563 tacea another pair of glands occur, the antennal or green glands which also appear to belong to the same series. A further point is also to be mentioned. In both Acerata and Crustacea the genital ducts open at the base of a pair of appen- dages near the middle of the body, and although that exact homology is lacking as to position which is seen in the case of the segmental organs, still there is enough similarity to make one think that here, as well as in other forms, a pair of segmental ducts has become modified to subserve the purposes of the geni- tal system. Did space allow, these comparisons could be prolonged almost indefinitely, showing that while there is a general resemblance between the Acerata and the Crustacea, there exists a much closer one between Limulus and the arachnids. If we turn now to a comparison of the Acerata, or even the arachnids proper, with the hexapods, we are at once struck with the important differ- ences between them ; differences which prove that the two groups have but little in common, and that, so far as these two are con- cerned, the division Tracheata is an artificial and not a natural ‘aes We have already alluded to one important difference between the trachez in the two groups. A few other remarks may prove of value. Trachez are internal tubes for conducting air to the tissues of the body. They are not confined to the “ Tracheata” but occur in some of the terrestrial Crustacea. This was first pointed out by Lereboullet in 1851 in the sow-bugs (Oniscidz), and more lately it has been shown that these trachez which are developed inside the branchial lamellz are lined with a cuticle which is raised into folds, comparable to the so-called spiral fila- ment in the trachez of the hexapods. The inference to be drawn is that trachez in the arthropods are not of phylogenetic signifi- cance, but have arisen from a necessity of conveying air to the blood and tissues in an air-breathing form. The thickenings of the cuticular wall, whether spirally or irregularly arranged, are intended to prevent the collapse of an otherwise delicate tube. In both spiders and hexapods there are developed from the hinder division of the digestive tract excretory organs which are known as urinary or Malpighian tubules. The writer holds that these are not to be regarded as indicating any especial affinity between the two groups, but like the trachez are produced by 564 The Inter-Relationslups of Arthropods. [June, environment ; though it must be admitted that the reason why a terrestrial life should cause the development of these organs is not as easily explained as in the case of the tracheæ. In proof, however, of the point made, it may be stated that in those amphi- pods which like Gammarus and Orchestia are more or less terres- trial in habit, similar tubes are developed from the same portion of the alimentary canal, and further that their size and length is directly proportional to the more or less terrestrial habits of these forms. The same is apparently true of some of the isopods, though on this point our information is deficient. _ Another point usually emphasized is the fact that in the Crus- tacea a biramose condition of the appendages occurs while this — is not known in the “tracheates.” The studies of Lankester on Apus have shown how this biramose condition arose, and the fact that frequently it is lacking in the Crustacea would tend to indi- cate that it might have existed in the ancestors of the “tracheates”’ and have been lost in the present forms. Even more important is the fact that such structures are not unknown in the “ trache- ates.” They occur, as James Wood-Mason has shown, in the thysanures, and Patten has described a similar state of affairs in the embryos of the cockroach. _ So far as our present knowledge goes we can say nothing as to the primitive position of the antennz of hexapods ; whether they be processes of the procephalic lobes somewhat like those of Peripatus or appendages which originally belonged to the post- oral series and which have moved forwards to a pre-oral position as have the similarly named appendages of the Crustacea. In the former case the differences in this respect between the hexapods on the one hand and the Crustacea and Acerata on the other will be seen to be very great. If the other view prove to be the true one, these organs of course will have less importance from a taxonomic standpoint. Still the differences will be very marked. That the former view is correct I am inclined to believe. If we accept it and regard the antenne as something entirely repre- sented in spiders and Crustacea and then make a serial compari- son as before, the result is as follows: HEXAPODA. ACERATA, i oe a Chel u, Maxi : Pedi ut, Labium, Jay Legh Leg 11. Ve Leg 11. Leg lll. 1885.] The Inter-Relationships of Arthropods. 565 This comparison brings the beginning of the abdomen in the same position in each group, but we have no other features to test its validity as we had in the case of the Acerata and Crusta- cea. In the hexapods there is nothing which in any way resem- bles a segmental organ. The hexapods have no liver, an organ voluminously developed in Acerata and Crustacea; their genital ducts terminate at the end of the body, and no evidence as yet presented points to the conclusion that they are to be regarded as modified segmental organs. With regard to the myriapods the problem is more difficult, and our knowledge of the development is too scanty to throw much light on the subject. The attempt has often been made to homologize the mouth parts in the two groups, but as yet with not very satisfactory results. A few morphological facts may prove suggestive. As is well known the myriapods are divided into two groups, Chilopoda and Chilognatha, represented by Scolopendra and Julus respectively. In the Chilopoda the geni- tal ducts terminate at the end of the body beneath the anus, in the chilognaths near the anterior end of the body, in a position almost comparable to that in the Acerata. In the chilopods the stigmata occupy the same position (between the dorsal and ven- tral plates) as in hexapods, but in the chilognaths they may occur on the ventral plates or even in the bases of the legs. Ap- parently in both groups the antennz are pre-oral in position; in the chilognaths their nerves arise in advance of those to the optic organs. In this connection more knowledge, especially of the head, is desirable concerning the curious fossil myriapod, Acanther- pestes, described by Mr. Scudder. Scolopéndrella will also repay investigation. In these forms, between the bases of the legs are the openings of peculiar organs. Mr. Ryder regarded those of Scolopendrella as tracheal stigmata ; Mr. Scudder those of Acan- therpestes as supports for branchiz. It may turn out, indeed it is probable, that both are the outlets of segmental organs. The few facts here presented, when taken together with the preceding remarks on trachez and Malpighian tubes, would allow the supposition that the myriapods may have but little relation- ship with either hexapods or spiders, and even that chilopods and chilognaths are not so closely connected as is usually supposed. VOL. XIX.—NO. VI. 37 566 The Inter-Relationships of Arthropods. [June, The discovery by Moseley of trachez in Peripatus at once transferred this form to the tracheate phylum, and much was expected from it as throwing light on the origin of the other air- breathing arthropods. To the writer it does not appear to have any close relationship to any of the other “tracheata,”’ but still most of all to the chilognaths. Still it is not proven beyond a doubt that it is an arthropod at all. The so-called antenne are always pre-oral (as shown by Kennel in the embryo and Balfour in the adult), and receive their nerve supply from the procephalic lobes in advance of these nerves to the eyes; thus allowing one to compare them with the pre- oral appendages of worms. The trachez and stigmata are not metamerically arranged, the latter opening more or less irregu- larly over the surface of the body and legs. The legs themselves are not distinctively arthropodous, while the numerous segmental organs indicate, as has often been pointed out, a very primitive form. Indeed, one has but to imagine a Syllid worm to leave its natural element and take to the land, losing the sete of its para- podia and developing claws at their extremities, losing its median antennz and developing tracheal pits for respiration and salivary giands to moisten its food, and Syllis becomes Peripatus. The other changes would be few. It would still retain its lateral ten- tacles, its segmental organs, its peculiar sympathetic nervous sys- tem and many details of its digestive tract. In fact Peripatus, in _ the light of recent studies, appears nearer the polychztous anne- lids than to any of the arthropods unless possibly the chilognath- ous myriapods. Recapitulating now the results of this hasty sketch, we arrive at the following conclusions: Peripatus has departed the least from the ancestral annelidan stock, the hexapods the farthest. These then will form the extremes of the series. The Acerata and Crustacea should be placed near each other, but which is the higher is a question. For instance, in the one only one pair of segmental organs remains, and these have lost their external ducts, while in the other group two pairs of these organs are functional through life. On the other hand, two of the post-oral ganglia of the Crustacea have moved to a prestomial position and have joined the supra-cesophageal ganglion, while in the : ne Acerata but one ganglion has been completely transferred and o this has not yet become wholly united with the ganglion formed 1885.] How the Pitcher Plant got its Leaves. 567 by the procephalic lobes. The position to be occupied by the myriapods can only be decided by further study. As will be seen, the points requiring further investigation are many. We at the same time know more and less of the arthro- pods than of any other group of the animal kingdom, unless it be of the birds. The literature descriptive of the species of in- sects is enormous, but when one tries, for the purpose of exact comparison, to find out from books some of the simplest points of tracheate anatomy, he is met with only vague and generalized statements or with no information at all. It may be that further study will show that the conclusions reached above are founded on insufficient data, but we think it must be admitted that so far as Crustacea, Arachnida, Limulus and the hexapods are con- cerned, the points here made are well sustained by our present ‘knowledge. What is especially needed is a more exact know- ledge of the arthropodan brain. The papers of Newton, Dietl, Flogel, Brant and others are good, so far as they go, but unfor- tunately they leave many and the most important points unde- cided. The same may be said of almost every other point in arthropodan anatomy except the morphology of the appendages, and even on this point much work remains to be done. :0: HOW THE PITCHER PLANT GOT ITS LEAVES. BY JOSEPH F. JAMES. 0. the many curious plants which have been given to the world by America, the pitcher plants are among the oddest. They form a family which belongs entirely to the new world, where the species are widely dispersed. One of them is found in South America, one in California, while the others are natives of the Atlantic seaboard. A single one of these extends north- westward to Minnesota and British America. The feature which is common to these widely-scattered forms is the hollow leaf, making a sort of pitcher into which insects fly or fall or walk. When a leaf departs as far from the normal shape as does the leaf of the Sarracenia, it is always interesting work to try to dis- < cover the causes which have lead to the divergence. To do this it is necessary to go far back in the history of the world and find an ancestral leaf from which it could have come. This necessi- ‘tates the examination of the various allies and relatives of the + 568 How the Pitcher Plant got its Leaves. [June, plants, for by so doing it is often possible to find the line along which they have descended. It seldom happens that all traces of this line have been destroyed. Here anc there a faint or obscure mark gives a clue; one thing leads to another, until at last it be- comes easy to trace the line of development to the original start- ing point. To do this it will first be necessary to give some account of the pitcher plants now living in the new world. d A a Fig. 1, _ The simplest form of leaf in the family is found in Heliam- o phora, a native of Venezuela in South America. It is a hollow tube with a narrow opening extending nearly one-fourth the way to the bottom, and with a small rudimentary hood at the top (Fig. 1). Nearly the whole of the interior of the leaf is lined with hairs, those at the bottom long and slender, and those at the óp short and thick (Fig. 2). They do not seem to be either 1885. | How the Pitcher Plant got its Leaves. 569 secreting or absorbing hairs, but serve simply to prevent the . escape of insects which have once found their way inside. This may be regarded as the nearest living equivalent of the original and ancestral form, but even it has, of course, been greatly modi- fied to suit altered conditions. > Fic. 3.—Leaf of Sarracenia purpurea. Next in order, but a little more modified, comes the widely dispersed Side-saddle flower (Sarracenia purpurea) of the bogs of the Eastern and Northern United States. In this species the leaf forms a more perfect tube, open only at the top, and surmounted 570 How the Pitcher Plant got its Leaves. [June, on one side by an upright hood (Fig. 3), the inner surface of which is thickly covered with short stiff hairs, all pointing down- wards. The interior surface at the bottom of the hollow is lined with slender bristles (Fig. 4). These extend about one-third of 4.—Hairs of Sarracenia pur- Fic. purea,; b, base; a, top. over the first one. The hollow is more complete ; the hood is conspicuous and attractive; the smooth surface at the center of the hollow is a more effectual safeguard against the es- cape of insects, and the way better adapted to secure insect prey. Still the pitcher is open to the rain, se- cretes little or no nectar, and absorbs the juices of the insects it captures in the form of a liquid manure only. The next step in advance is found in a southern species of the genus with larger and more upright leaves, known as Sar- vacenia flava. The arrangement of the hairs in the interior of the leaf is the same : but a saccharine secretion just below the hood shows a marked difference, and is a more effectual lure to insects than merely a colored surface such as there is in the the way up. Then comes a per- fectly smooth, glaucous surface, extending another third of the way, and above it is another set of hairs similar to those on the hood.

In the first place the hood bends over the orifice of the leaf and shuts out all rain. Secondly, the hood is marked on the posterior portion with white translucent spots and reticulations, and honey is there secreted. Thirdly, the fine velvety pubescence extends one-third way down the pitcher, and then the hairs become longer, coarser Fig. 7. Fig. 6. Fic. 6.—Leaf of Darlingtonia. Fic, 7.—Hairs of Darlingtonia; 4, base; a, top. and more bristly as the tube narrows. Fourthly, a secretion is formed at the bottom of the pitcher which has the peculiar prop- erty of asphyxiating insects so unfortunate as to fall into it Fifthly, there is found to be a honey-baited pathway running from the ground up along the wing of the leaf to the hood, and a short way into the orifice. These are many and curious changes. A marked advance 572 How the Pitcher Plant got its Leaves. [June, over the open, honeyless pitcher of S. purpurea is at once mani- fest. But a still further advance is found in Darlingtonia, the third genus of the order and a native of California. In this the leaves are very long, stand upright and have a peculiar twist not found in any other species (Fig. 6). The hood, in addition, forms a vaulted arch, mottled with spots and reticu- lations. The only entrance to the leaf is from below, and on each side of this entrance is a long appendage, the whole likened to a fish tail. The inside of this secretes honey and is covered with hairs. The interior of the pitcher is lined with vast numbers of hairs, which become longer and more bristly toward the bottom (Fig. 7). A secretion is found here that has the power of decomposing the bodies of the insects which have been entrapped. On the outside, running along the wing, from the ground to the orifice, is a honey pathway which lures creeping insects to their destruction. The wings or fish-tail, at the top of the pitcher, attract flying ones. In these species of plants there is a regular gradation from the simple to the complex. From the Heliamphora with its open pitcher and small hood, to the Sarracenia purpurea with upright, less open pitcher and larger hood; thence to the S. variolaris through several stages of less complexity, with its almost closed pitcher, power of secfeting honey and digestive fluid; then to the more remarkable Darlingtonia, with its large twisted leaves, with vaulted hoods and fish-tail appendages, decomposing fluid and honey-secreting apparatus. Scarcely any of the steps showing the progress are needed to complete the line of development. It can be traced directly from Heliamphora to Darlingtonia, and it is only necessary to have an ancestral form from which to start to have a complete pedigree. It seems probable that the water-lily family and the pitcher- plant family had a single ancestor in common. This ancestor was aquatic, or at least an inhabitant of swampy places. It had _ small, probably peltate, perhaps reniform leaves, and these had - hollow petioles. The inner space was lined with hairs as are now the inner surfaces of the stems of Nymphza and its allies; it had a four or five parted flower, with many stamens and a broad ERS = From such an ancestor came’ two or three branches. One of = these developed into plants having an aquatic habit, large leaves x i 1885.] How the Pitcher Plant got its Leaves. 573 and long petioles, and peduncles like those which are found at present in the water-lilies. The other branch diverged to form plants living in boggy or swampy grounds, with pitcher-like leaves whose insectivorous proclivities were developed later on. The development of the members of the water-lily family from this hypothetical ancestor can be accounted for thus, The aquatic habit must be confirmed, the depth of water increased, the leaves grow larger and the change is complete. But to transform a peltate or reniform leaf into a pitcher requires much more modi- fication. Suppose, however, that water lodging on the upper sur- faces of some leaves was retained there ; and that in this water insects were caught and drowned. Suppose the constant pres-' ence of the water caused the decay of the substance of the leaf at its insertion on the petiole and allowed the water to penetrate the hollow. This liquid manure might assist the plant in its growth. The habit of catching water by means of a peculiarly cup-like leaf, would be transmitted from generation to generation. Each successive one would have larger and larger petiolar spaces, and correspondingly smaller leaves. And this because the liquid manure supplied directly to the root would enable the plant to do with less and less leaf surface as the nutriment was more and more fully elaborated ; until finally the petiole would have grown into a hollow pitcher-like affair, and the ‘ leaf-blade would have dwindled to a rudi- ment. The primitive pitcher plant was probably but little less specialized than the least one now known. This one has already been described under Heliamphora. The various modifications of structure incident to change of form now come under consideration. The internal hairs of modern water-lilies were likely represented in the ancient form | ; from which they are descended. In spe- cies now living these hairs are stellate, with from three to five arms or projections (Fig. Fic. 8.—Internal hairs of 8), and they thickly line the interior spaces staan A et of the petioles of leaves and the peduncles of flowers. Exposure to air and adaptation to altered conditions would naturally cause a change of form. They doubtless lost first one and then another ~ 574 How the Pitcher Plant got its Leaves. [June, projection, till they were reduced to a single one. This one would be, at first, of the same size and shape the whole length of the pitcher. Then, in time, as it was found that those at the bottom would not need to be so strong, they would become longer and more slender, while the uppermost ones would be stiff and harsh to more effectually prevent the crawling up of insects. As the specialization proceeded, a less number of hairs would be required and a smooth space near the center of the wall of the leaf would be found a still more effective guard against the escape of the prey. Fic, 9.—Heliamphora, As soon as the capture of insects became a necessary part of the existence of the plant, or even an advantage to it, honey would be developed to serve as an attraction. This, from at first a merely sweet secretion, would acquire, if it served a useful end, _a character calculated to retain the insect. If, however, the honey __ had too bad an effect, the end in view would be defeated, for it = would in time be rendered unattractive. For insects would in _ their turn, become modified to resist the temptation. So then the next step in the onward march would be to keep the honey of the lure pure, but to modify the character of the secretion at 1885.] How the Pitcher Plant got its Leaves. 575 the bottom of the pitcher so as to retain and eventually convert the insects caught into nutritious material for the plant. This secre- tion would become a further necessity, and its character would be otherwise changed when, by a change in the nature of the hood, rain was excluded from the cavity. Finally, as a further lure to insects appendages brightly or curiously colored would arise and assume a form calculated to attract them. That these were the steps leading from the simplest to the most complex form of pitcher is shown in the actual forms living to-day. There can LS hardly be a better illus- j tration of the theory of descent with modifica- tion than is found in this one family. It be- comes, therefore, a mat- ter of peculiar interest to still further continue the study, and to inves- tigate the causes which led to the peculiarities of the flowers they possess, and likewise to study the reasons for their present geograph- ical distribution. The-flowers of Heli- amphora are described as being regular, with Fic, 10.—Sarracenia. four, five or perhaps, at times, six sepals, no petals, an indefinable number of stamens, and a single, entire pistil (Fig. 9). There are one or two flowers on a bracted scape. In the flowers of all the species of Sarracenia a peculiar modification of the pistil is observed. Along with the five sepals and five petals, it is found that the pistil has assumed a broad, umbrella-like shape (Fig. 10) with the stigmatic surfaces at the ends of the rays. These are five in number and extend upwards as the flower hangs. A single flower is at the top of a naked scape. The flower of Darlingtonia (Fig. 11) is-solitary at the top of a bracted scape, has five sepals and five petals, only twelve or fifteen stamens and a style with a five-rayed stigma. 576 How the Pitcher Plant got its Leaves. [June, In the first of these, the South American form, is probably to be found the nearest approach to the original type of flower, The single floral envelope, ‘indefinite number of stamens and simple pistil, seem to indicate a comparatively un- specialized form, which cor- responds to the simplicity of the leaves. In the modern Nympheza or water-lily, there is a great number of petals, but these could be readily re- garded as some of the numer- ous stamens of a few-sepaled or petaled flower which have been transformed into petals, In the ovary of Nuphar (spat- ter dock) there is an approach to the simple ovary of Heli- amphora, accompanied, to be sure, by modifications which may be regarded as necessi- tated by an aquatic life. So that it does not require much to assume that in the flowers as in the leaves, the water-lilies and the pitcher plants are closely allied. j fii Fic, 11.—Darlingtonia. The umbrella-like stigma of the side-saddle flower, as well as its whole arrangement, is to be regarded as a modification inci- dent to cross-fertilization ; for in these plants seed is not perfected otherwise. On this account alone it would be expected to diverge widely from the primitive form. But there is, in the closely allied poppy family, an approach to this spreading umbrella-like stigma, whose whole large expansion may undoubtedly be refered to the necessity for cross-fertilization. : Lastly, in the Darlingtonia the flower is also greatly modified. This time the change has taken place in accordance with changes ~~. inthe leaves.

Nor is such a suggestion an unreasonable one when the highly specialized condition of the plant is con- sidered. If once a hint in that direction showed itself, and any benefit was thereby derived, it may be considered as certain that the direction would be persevered in until both leaves and flowers had departed very far from the original and normal type. This is exactly what has happened. Coming finally to the geographical distribution of the order, the facts show plainly how one could have been derived from the other. The original home of all was most likely in South America, where one species still lingers. This original form may be imagined as conveyed from its place of origin to the south coast of what is now the United States, most likely by means of the Gulf Stream. Finding a suitable place for living, the some- what changed conditions would have modified the emigrant into a plant with a leaf like S. purpurea, This once fairly established spread all over the country where there were favorable condi- tions for its growth. If we imagine this dispersion to have been during the continuance of the Tertiary period, there would have been ample time for great modification to take place. Then it was, in all likelihood, that the Darlingtonia began to develop in its own way. After a long period of time the Tertiary epoch was brought to a close. A great change came over the face of the country, and many of the intermediate forms between Sarra- cenia and Darlingtonia became extinct. Change in climate and in conditions produced by the glaciers which covered the country at one time was an efficient agent of extinction. At the same time the unextinguished forms would have continued to become modified in various ways until they became as they are now found. The history of this one family, peculiarly circumstanced as it is, shows the possible origin of a number of forms from one common ancestor, different though they are from each other at present. In every part can be traced the werkings of evolution. In leaf and in flower the steps can be followed. Even in the geographical distribution of the living species it can be seen. In some. families of plants the steps are not so plain because encum- bered by a larger number of generic and specific forms; but 578 An Adirondack National Park. {June, could the gaps be filled in any one species or order, the line of descent might be followed through the ages to one common and generalized type. The varied forms to which that type gave rise are seen in the different genera of different natural orders. The time is far distant when all these can be traced step by step to their remote origin. But every little adds, and eventually a mon- ument will be raised which will tell how, and perhaps when, each individual plant reached its present state of perfection or de- generacy, :0: AN ADIRONDACK NATIONAL PARK.

East of the Rockies and within a territory of four million thickly populated square miles, not a single national breath- ing ground exists. In the great Empire State lies an elevated country of vast area, as lovely as the mind of man has mental imagery to conceive. It stands to-day the prey of timber thieves and game butchers, so neglected by the State that its boundary lines have been lost, its forests denuded, its waters left to evapora- tion and outrage, and its maintenance denied of all but the small- est pittance. It is the particular surface of the globe that gives one a glimpse through the corridors of time. It is a part of the cradle of the earth. Here are blue-gray hypersthene and con- torted gneiss rocks—the first forms in nature’s attempts at world building. Before organisms came into existence these rocks formed their part in the stable foundation of the earth. The Adi- rondack region, then, is grandparent to the remainder of the globe. The Hudson, which rises in its clouds, is perhaps the oldest river in existence, being the ancient outlet of the Great Lakes’ ancestor, and hence the grandparent of waters. Will any one say that the Government of the United States ought not to be charged with the care of the portions of these aged relics which a great State has given over to weeds and bandits ? _ Two great watersheds lie within the State of New York at a ght angles to each other. They so interlock that writers have 1885.] An Adirondack National Park. 579 been led to regard the State as one watershed, The dividing lines are too apparent, however, and the physical, climatic and geolog- ical differences necessarily form divisions of the State. Tke eastern or Adirondack watershed runs almost north and south, throwing its waters north into the St. Lawrence, and sou into Long Island sound. The western watershed runs nearly east and west, at right angles to the Adirondacks, It throws its waters from the interior chain of lakes, north into Lake Ontario. Its southern drainage flows at oblique angles into Chesapeake bay and the Gulf of Mexico. The northern drainage of the western watershed occupies seven thousand square miles of territory, of which four hundred square miles are of lake surface, under the names of Oneida, Cayuga, Seneca, etc. This watershed has been made subservient to the necessities of commerce and industry. Besides being natural reservoirs, its lakes have been regulated to maintain a uniform flow through the Oswego river of six hundred thousand cubic feet of water per minute, during all seasons of the year. Seven dams on this stream, constructed by the state, provide hydraulic advantages equal to 140,000 horse-power. Thus the western watershed, by fostering gigantic industries, valued at millions, repays the State for the expenditure involved in its care. The Adirondack watershed is of a different nature; its waters are of little commercial or industrial importance. Its rivers, the Moose, Beaver, Grass, Raquette, Salmon, Au Sable, Oswegatchie and others are high, turbulent and destructive in the spring. In the summer they are dry. The Hudson itself would be insignificant were it not an arm of the sea, scoured out and kept deep below Albany by the tides. The Adirondack region has resisted all attempts at cultivation, otherwise it would be largely populated. Its mission is of higher importance to man than that of a mere industrial and commercial utility. Here is one of nature’s great laboratories for the genera- tion of pure air and the maintenance of stable atmospheric condi- tions. Its many cool lakes and babbling brooks form a natural resting and invigorating ground. It comprises the highest land in the State, ranging from one thousand to five thousand feet in elevation. In this elevated domain are upward of two thousand lakes and lakelets abounding in clear cold waters—the ideal land of the 580 An Adirondack National Park. [June, poet and the artist. The wild deer laves in the mirroring lake or lies sequestered in the deep ravine. The trout break the placid surfaces at night and the note of the whip-poor-will echoes from valley to peak through wood and clearing. The catamount watches from the creviced rocks and the black bear hibernates in the recesses of the forests. This is nature’s miniature park of the earth. The mountains, cascades, rivulets, lakes and precipices are all scenic features in miniature, It is not a Yellowstone park, There are no three-mile vertical projections into space, no spout- ing geysers, no vast areas of sage brush, no great obsidian cliffs, no fossil forests, no bad lands of towering buttes and no bottom- less cafions. All such awful sublimity is here molded in minia- ture—a playground of the gods. Until the State survey began its work, ten years ago, but little was known of the Adirondack region. The only maps in posses- sion of the comptroller were some curiosities made by colonial and early surveyors. So uncertain were the boundary lines that the State lost thousands of acres of lands, and was uncertain of any of its possessions. Investigation developed the fact that the State lands were first sold for little more than five cents per acre. The timber was immediately cut and the land allowed to lapse to the State for unpaid taxes. Wherever the second growth became valuable the lands were repurchased at tax sales, denuded and again left barren for the State, which now owns about eight hun- dred and ninety-five square miles. The watershed comprises about three thousand square miles which are available for park purposes. The highest point in the State is Mt. — in Essex county, - which rises 5344 feet above high tide. It is the monarch of the Adirondacks, Mt. MacIntyre, 5112 feet, approximates this alti- tude. Seventeen peaks exceed 4500 feet, forty-four rise above 3000 and seventy between that height and 2000 feet. Mt. Washington, with its bridle-path and its inclined railway, _ has long enjoyed a monopoly in the East. A change is approach- ing. A new star has appeared in the sky. It is Mt. Marcy— _ fature’s colossus to a noble name and the most ideal mountain _ on the face of the globe. It is no mere stone heap, Resting on its bosom are great forests, lofty spurs, precipices and lakes, Here also is Lake Tear-of-the- clouds, within one thousand feet of the : fameuit-—nthe supra-cloud source of the Hudson. It is the high- 1885. | An Adirondack National Park. 581 est water in the State. The poetic State surveyor, Mr. Verplanck. Colvin, best describes it in these words: “ A few summers since I stood for the first time on the cool mossy shore of the mountain springlet lake, Tear-of-the clouds Almost hidden in the gigantic mountain domes of Marcy, Sky- light and Gray peaks, this lovely pool lifted on its granite pedestal toward heaven, the loftiest water-mirror of the stars; beseeching, not in vain, from each low-drifting cloud some tribute for the sources of the Hudson; fresh, new, unvisited save by the wild beast that drank ; it was a gem more pure and delightful to the eye than the most precious jewel.” Mt. Marcy is the center of the scenic, sporting, artistic, poetic and scientific interest in the Adirondack region. The timber limit is here well defined at 4900 feet above the sea. The crev- ices are densely filled with stunted evergreen and the deep valleys between the mountain crests are covered with forests of pine, spruce, hemlock, beech, birch and other trees. Snows are almost perpetual here, summer lasting but two months. So far as may be judged by one who has visited each, there is little difference in temperature and climatic conditions between an altitude of 5000 feet on Mt. Marcy and 12,000 feet elevation in Wyoming. This similarity may be accounted for by means of the ameliorating in- fluences of the Pacific coast on the Rocky mountains. Mt. Marcy is beginning to attract many visitors and is certain to draw heavily on the traveling public as soon as its grandeur and attractions become more generally known. It was seldom scaled until in 1875 the State survey projected a line of levels to its highest oint. Since then there has been a gradual increase of summer visitants. The Indians called Mt. Marcy Ta-ha-wus, signifying “ I cleave the clouds.” Observations tend to show a considerable decrease of rainfall in the State. This decrease has been attributed to the general denuding of forests in the Adirondacks. The iron industries alone have been shown to consume the wood on six thousand acres of land annually, to say nothing of the trees utilized as lumber. While no one of note has disputed the influence of for- ests on rainfall, such influence has not been satisfactorily ex- plained. The following explanation is offered : The Gulf Stream projects its waters along the Atlantic coast. It furnishes moisture to the winds which sweep over the land, VOL. XIX.—-NO. VI. 38 582 An Adirondack National Park. [June, tempering the climate. Formerly when these winds beat against the Adirondack highlands there were vast.areas of brush-topped ever- greens and myriad-leaved trees to act as electrical conductors and precipitate moisture in the form of rain. The forests have been ruthlessly cut and now the moist winds beat against the rocks and burst in floods of water or in form of hail, or sweep past with their possibilities of evenly distributed rain. Nature takes her swift vengeance. The river bottoms show at the surface and the hur- ricane and hailstorm beat down the structures made of the forests. As Mr. Colvin states in one of his reports, the forests hold snow in compact depths which melts slowly, contributing a regular quota of water during three-fourths of the year. The cones fall from the evergreens, become pulverized and overgrown with moss. These cone beds hold water to such an extent that they were named “ hanging lakes.” Wherever the forests have been denuded the snow banks and cone beds have disappeared and thus, concludes Mr. Colvin, nature has been robbed of her reservoirs. It seems incomprehensible that so great a commonwealth as New York has appropriated so little to maintain a survey of its own valuable possessions. No foreign government expends such a pittance for surveys of bergs, as the Empire State has for its entire area. The necessities of war, for which we must prepare in times of peace, demand the most minute and exhaustive surveys. The exchange of real estate, the prevention of needless lawsuits among citizens, and the taxation system, demand accurate sur- veys. The lack of good topographical maps may yet cost a thousand times the amount required for engineering. Instead of five thousand dollars occasionally, the State should have appro- priated seventy-five thousand annually for this purpose. ihe growing demand that the Adirondack region shall be set aside as a public park with liberal appropriations for its protec- tion, superintendence and surveys has been met with little legis- __ lative encouragement, which so far only amounted to successive _ and expensive commissions since 1873. There is not a prairie State to-day that would not give millions for one Mt. Marcy. New Yorkers have migrated to every portion of the Union in great numbers. Had they a voice in the matter, the Adirondack region no doubt would be surrendered to the United States and __ cared for as jealously as is the Yellowstone park, with full appro- ~ Ppriations for surveys and maintenance. If the proper steps were taken, there is little doubt that the consensus of opinion of the - York has shown itself incapable of caring for its possessions. 1885.] Editors’ Tabie. 583 EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. The relations of the National Academy of Sciences to the Government deserve the attention of the scientific men of the country. There are two views of the nature and functions of this body. One of these is, that it is the advısor of the Govern- ment in such matters as come within its scope. As it is most likely to be called upon for opinions in questions of applied sci- ence, it follows that a considerable number of its members should represent that kind of ability, rather than advanced positions in original research in pure science. The other view is, that the academy is a body which includes a definite number of men who lead the progress of pure science in the country, irrespective of utility to the Government, and that as such, its membership con- stitutes an order of merit which is the highest within reach of the American scientist. From this standpoint its relations to the Government flow simply from the character of its membership, and not from any especial modification of its organization. There is no reason why the two propositions above stated may not both be realized in the academy. This is doubtless the opin- ion of the large majority of its members, and indeed represents the actual state of affairs in that body. It is, nevertheless, easily seen that however combined, the two ideas are themselves dis- tinct, and that care will always have to be exercised to preserve a just equilibrium between them. The fact that a large proportion of its members are in the employ of Government bureaus can excite no adverse criticism, and is indeed a necessary consequence of the large number of experts required for the Government ser- vice. But the academy must be protected against possible con- sequences of this fact. In the interval between the annual meetings of 1884 and 1885, two members of a committee appointed to investigate a question affecting one of the bureaus of which they themselves are em- ployees, were requested to resign from the committee by the chief of the bureau in question. This was in obedience to the rule that a department of the Government cannot be criticised by its subordinates. It requires no argument to show that if this rule be carried out with reference to the Academy of Sciences its use- fulness as an independent body is at an end. There is also 584 Recent Literature. [June, another danger which flows directly from the same or a similar attitude on the part of heads of bureaus. These gentlemen, by filling up the academy with their employees can obtain practical control of its decisions. This would be immensely convenient to them under various circumstances, but it would introduce an ele- ment of corruption into the academy from which it has been hitherto happily free, and which would deprive it of the respect and confidence of the country. So long as the bureaus remain under the direction of their present- heads, such contingency is remote; but changes for various reasons, political or otherwise, are by no means impossible. It is easier to provide against pos- sible evils than to reform them when they are upon us, —— The papers read at the late meeting of the National Academy of Sciences include several of first-class importance in systematic analysis. Such is the paper of Mr. Scudder on the palzozoic insects, and such that of Dr. Sterry Hunt on the classi- fication of the natural silicates. Of the same character was the paper of Professor Gill on the orders of fishes; and to the same class belongs that of Professor Cope on the phylogeny of the placental Mammalia. These memoirs, if published in extenso in the next volume of the memoirs of the National Academy, will give it a value commensurate with the place the society holds among those of the country. Of almost equal but less compre- hensive importance were the three papers read by Professor Packard on Palzozoic Crustacea, and by Professor Cope on the Pretertiary Vertebrata of Brazil. The papers in other depart- ments were less important than is sometimes the case at the meetings of the academy, a RECENT LITERATURE. against destructiv ts, and the economic compensations of the more extensive losses from the depredations of insects; general introduction to systematic and practical entomology. 1 Lehrbuch der Mitteleuropiischen Darig aiene mit einem Anhange: Die £ Sey Vwi É achte Auflage von Dr. J.

Craus’ ELEMENTARY Texr-Book oF ZooLocy.—We have already called attention to the first part of this work, which has been translated by Sedgwick and Heathcote. The second part embraces mollusks, Tunicata and vertebrates, the spaces given to the last group being in our opinion too little; in such a book cer- tainly one-half of the matter should be devoted to vertebrate ani- mals. In point of treatment, and excellence of the illustrations the high character of the first part is well sustained in this the concluding part. The old meaningless group of Molluscoidea is, however, retained for the Bryozoa and. Brachiopoda. To place these two groups of what may with safety be regarded as com- posite types of worms in a group equivalent in rank to the Ar- thropoda or Vertebrata shows lack of judgment. The author re- marks in justification: “ With the increase in our knowledge ot their developmental history, it appears more and more probable, not only that the two groups are descended from an ancestral form common to them and the annelids, but also that in spite of the considerable differences between them in the adult state, they are in reality closely related, a supposition which agrees with the great resemblance of their larve.” The Tunicata are placed next to the vertebrates, above the mol- lusks and Molluscoidea, a position now seemed warranted. The treatment of the Mammalia is, like that of the birds, anti- quated, no reference being made to the new groups of extinct forms and the subsequent modifications which should be made in the classification of the class; besides, too little space is given als. . to this most important of all classes of anim Upnam’s FLORA oF Minnesota.'—The State of Minnesota is to be congratulated upon the appearance of so creditable a volume in its Annual Geological Report.

Arrica.—Kilima-njaro.— The account given by Mr. H. H. Johnston, before the Royal Geographical Society, of his stay at Kilima-njaro, adds more to our knowledge of the zoology and botany of the southern slopes of this great mountain than to its geography. The vegetation is luxuriant, trees ascend to nine or teh thousand feet, herbaceous vegetation is abundant up to 13,000 feet, and heaths and some shrubs linger to above 14,000 feet. The buffalo, koodoo and elephant appear to ascend even to the snow-line. Mr. Johnston saw the footprints of buffaloes at 14,000 feet, and came in sight of three elephants at 13,000 feet. A hyrax ascends to 11,000 feet. In the discussion which followed, Mr. Thomson described Kilima-njaro as an enormous mountain mass, some sixty miles long by thirty wide, upon the summit of which the great dome of Kibo and the peak of Kimawenzi were com- paratively small excrescences. On the southern side the country Chaga was formed of a series of terraces of fertile land, but on the northern side the mountain rose at an even angle from 3000 to 18,000 feet without a break by ridge or valley. The Egyptian Sudan.— Colonel H. G. Prout, an American engineer, formerly under the employ of General Stone, has con- tributed to the Exgineering News an account of the route from Suakin to Berber. This is of interest geographically from the light it throws upon the nature of the country, which from imme- diately behind Suakin to Wady Ariab, 118 miles from that place, is mountainous, the projected road passing, at about sixty miles from Suakin, through a defile 3000 feet above the sea. The map recently compiled from data furnished by the office of Naval Intelligence, shows this route, as well as those between Massowah and Kassala, and Korosko and Abn Ahmed. Gen. C. P. Stone contributes to Sctence an account of the climate of various parts of the vast region known as the Egyptian Sudan. From November to February inclusive, the province of Dongola is healthy, but in the spring months the heat is excessive, dust storms violent, and fever prevalent. The moist winds of early autumn increase the unhealthiness. At Suakin, the intense heat is the chief foe to health; but the province of Taka (capital, Kassala) and the district of Gallabat have, from June to October, a climate which is deadly to Europeans. At that season the rains are copious, and mingling with the floods of water coming down from the mountains of Abyssinia, cause the rich soil to become like a saturated sponge. Even the natives, in many districts, abandon the country from May to October, and reside in the desert. 1 This department is edited by W. N. Lockincron, Philadelphia. 588 General Notes. [June, Asta.—The Lower Helmund—The valley of the Helmund, at the point where it was struck by the Afghan boundary commis- sion, below its junction with the Argandab, is narrow and limited by ranges of rolling clay or sandstone hills. Beyond these ridges rise other similar ridges, forming the dashés, or rolling plateaux of Southern Afghanistan. This desolate country is full of ruins. “ From Lundi to Kala Fateh,” writes Major Holdich, “ one rides through and over the relics of dead kingdoms. The remains of forts, of deep-cut irrigation canals, of pretentious habitations which might have been palaces * are the common fea- tures of the landscape. Broken pottery strews the ground some- times for miles ata time.” All are built of mud or sun-dried bricks. During the whole of its lower course until it disappears in a hamun or swamp, it receives no tributaries. About Nadali are innumerable mounds, some of which, though always bearing ruins on their summit, are clearly stratified, and are therefore thought to be natural. Discovery of the Sources of the Hoang-Ho—The proceedings of the Royal Geographical Society for March contain translations of two letters sent by Col. Prejevalsky to the /uvalide Russe. This intrepid traveler left Urga (a town in Northern Mongolia, situated on a branch of the Angora and south of the Irkutsk) on Nov. 8, 1883, and soon reached the vast desert of Gobi, which measures 2650 miles from east to west, and about 700 from north to south. The northern part of the desert is still a steppe region covered with excellent grass; but Central Gobi consists of perfectly bare flat spaces covered with pebbles and cut upat intervals by lone strati- fied ridges, while Southern Gobi is covered all over with quick- sands, the remains of shoals and dunes of the once wide Central Asian sea. Terrible frosts in winter, without snow, and almost tropical heat in summer, with frequent storms, characterize this barren, rainless, riverless region; yet every part of it is inhabited by Mongols. Crossing the Khurkhu ridge, forming the eastern edge of the Altai, the southern desert, or Alashan, was entered, and a stay was made at Din-yuan-in, where the Alashan range runs like a wall between the desert and the cultivated banks of the northern bend of the Yellow river. Crossing the Nan-shan range, part of the unbroken wall which stretches from the Upper “Hoang-ho to the Pamir, Col. Prejevalsky then entered Kan-su, and prepared to go in search of the hitherto undiscovered sources of the Hoang-ho. On his way he passed the plateau of Lake Koko-Nor, 10,800 feet above the sea; and then crossed the ridge of Burkhan-Buddha by a pass 15,700 feet above the sea. The circumference of Lake Koko-Nor is given as 16624 miles. Sixty- seven miles from the pass the sources of the Yellow river were reache wo streamlets, flowing from the south and west, out of the mountains scattered about the plateau, unite at an elevation i - of 13,600 feet. The infant river is fed by the numerous springs 1885.] Geography and Travels. 589 of the wide marshy valley (40 miles by 1314) of Odontala, or, as the Chinese call it, Sing-su-hai, or Starry sea, After a course o about fourteen miles, the river falls into a lake, the southern shores of which it colors with its muddy waters, then pouring out of it to the east it soon enters another lake, which it leaves a consid- snow-covered ridge of Amne-machin, its mad current tears through the cross strata of the Kuen-lun and flows toward China proper. After this our traveler went southward, but was stopped by the unfordable Blue river, or Di-che (Yang-tsze), and return- ing northward, made his way to Zaidam, after two serious en- counters with Tangutan robbers. Asiatic Notes —M. Donbrof has explored the upper course of the Selenka, and reached the hitherto unvisited source of this great tributary of Lake Baikal. According to Mr. Gowland, who has recently crossed the central range of Corea during a journey from Séul to Fusan, there are in this part of the peninsula no mountains above about 4000 feet in height, no characteristic volcanic cones, and no indications of mineral wealth. ‘The re- sources of the country appear to lie entirely in agriculture. M. Jos. Martin has arrived in Japan after a most arduous journey from the Lena to the Amoor, across the Stanovoi range of moun- tains. Dr. Gustave Le Bon is traveling in Nepaul. He is said to be the first European who has been permitted to travel through that country. AUSTRALASIA.— The North Coast of New Guinea-—Mr. Robidé van der Aa has recently published an account of two voyages to the north coast of New Guinea. In the first, the Mapia group of islands was visited, and the voyagers afterwards landed on Jamma, an island in Walckenaer bay, and a depot for the cocoanut fiber of the main land. About twenty-five miles south-east of Jamma is the mouth of a river, the Witriwaai, not found on any map. This was ascended to a large lagoon. About eight miles to the east is the Wiriwaai, with a strong current discoloring the water far out to sea. Sadipi bay, nearly a degree further east, is a deep and safe harbor. The houses here have at each gable end a pent- house roof, which comes so low that a hole is made to enable the occupants to crawl in. On the second voyage, the Amberno river was ascended for over sixty miles, when it shoaled, with a current of four and a half miles an hour. Mr. van der Aa argues from the size of this river (it is eight hundred yards wide) that it has a long course from the interior, cutting its way through the ' Rees mountains. Thus its upper waters may be navigable-——— Dr. R. von Lendenfeld has found that Mount Kosciusko is not the highest of the Australian alps. He has ascended a higher at some distance farther south. This is 7256 feet high, while Mount Kosciusko has been measured at from 7171 to 7176 590 General Notes. [June, feet. The newly enthroned peak is named Mount Clarke. The upper limit of trees upon it is 5900 feet. Above 6500 feet patches of snow are found on the lee side of the main range, at 6500 feet. AmErica.—Science states that several expeditions to Alaska are projected during the coming season. Gen. Miles, who commands in the military district, desires to acquire a knowledge of Cook’s inlet and the Tananah course and watershed, and it is hoped that a party under Lieut. Ray will be sent for the purpose. The party under Lieut. Abercrombie were unable to pass beyond the glacier alleged to obstruct the Copper or Atna river, about sixty miles from the sea. A party under Lieut. Allen left for the Copper river, June 30, and hope to cross the divide between that river and the Yukon basin and descend the latter. Lieut. Stoney is reported to have a new expedition nearly organized to continue his inves- tigations of the Kowak river. Evurope.—M. Rabot has explored Lake Enara and the valleys of the Pasvig and Talom, in Finland. The country is an im- mense forest, with lakes and peat bogs scattered everywhere, and the only means of communication is by rivers which abound in cascades and rapids. Lake Enara, drained by the Pasvig, is a veritable inland sea, with hundreds of islets covered with magni- ficent pine trees. The country around it, level and little broken, forms a rie fewest between the plateau of Finmark and the hills of Russian Lapland GEOLOGY AND PALAONTOLOGY. THE ORIGIN OF FRESH-WATER Faunas.—Professor W. J. Sollas gives to the world, in No. v, Vol. 111, of the Scientific Transactions of the Royal Dublin Society a review of the causes which have originated and limited the fresh-water faunz of the world. Three causes are admitted as proven: (1) the difference in chemical ` composition of the medium; (2) the severe character of the fresh- water climate; (3) the necessity for the suppression of a free larval existence. Although the first cause is doubtless a powerful one, it is not sufficient to alone account for the facts, as seems to 1885.] Geology and Paleontology. 591 and the severity of the climate the only obstacles, we might ex- pect that many more of the forms which crowd the coasts would work their way up the rivers. As a rule, however, the fresh- water forms are sfa distinct from the marine, retain their dis- tinctness everywhere, and, in time, are well marked as far back as the Mesozoic. It is therefore probable that the fact that the majority of marine invertebrata are diffused by means of free- swimming larvæ has been one of the chief obstacles to their spread up the rivers. These fragile and feeble larvæ always swim along with even an ocean current, and are utterly powerless to stem that of a river. Should a siow-moving marine animal suc- ceed in ascending some distance up a stream, its larvæ, if free- moving, would infallibly be carried out to sea. By a detailed examination of the forms which inhabit fresh water, Professor Sollas shows that in most of them the free larval stages are suppressed. Other causes may exist. Thus the absence of suit- able food is sufficient to account for the lack of carnivorous gas- tropods and cophaliper: i in the rivers. Fresh-water animals may be converted into marine in three ways: (1) by direct migration; (2) by the conversion of the area they inhabit into a fresh-water basin or lake; (3) by adaptation to a terrestrial or marsh-loving habitat, and subsequent exchange of this for a fluviatile or lacustrine one. The first method can scarcely occur with fixed forms, unless they are parasitic upon locomotive animals. Some prawns and crabs appear to have thus immigrated by compliance with the three conditions, but the in- stances are very few. The wide changes in the distribution of land and water that have perir place in the course of geological time offer a more probable mode of the gradual transformation of a fauna from a marine to a e antes one. The comparative poverty of the latter may be due to the escape of some species, as well as to the extinction of others. The earliest lakes known are of the Devonian period, and one Devonian fossil at least, Azo- donta jukesu, has been found. Helicidæ are found in the coal measures, and are probably the ancestors of the Limnæidæ. In the Lias and Oodlite numerous fresh-water mollusks occur, and Cyrena, Neritina and Hydrobia probably date from the Trias. Saectal genera of fresh-water mollusks were already distributed over parts of the Palæarctic, Nearctic and Oriental regions in Cretaceous times. The Tertiary lakes of the northern hemi- sphere have suffered from a glacial era, and the Caspian has be- come unwholesome by concentration of its waters, yet it retains a relic of a Tertiary fauna; while the Central African lakes have a remarkable assemblage of Mollusca. No marine mollusk is known to pass through a “ glochidium ” stage, like that of the Unionide; no marine Polyzoon or sponge produces statoblasts; no marine Phyllopod an ephippium ; and no Tubularian an egg in a horny shell like that of Hydra. 592 General Notes. (June, these are modifications suffered by fresh-water genera, are not shared by their marine relatives, and appear to be necessary to the existence of sedentary forms, as characteristic of fresh-water organisms. The wide distribution of a form introduced by float- ing timber is not probable until its developmental history has changed also. Tue BATRACHIA! oF THE PERMIAN BEDS OF BOHEMIA, AND THE LABYRINTHODONT FROM THE Biyort Group (Inpra).2— In these contributions we find important additions by eminent palzontol- ogists to the knowledge of the stegocephalous Batrachia of the regions named. In Dr. Fritsch’s volume we have the continuation of an extensive work which we have noticed at various times in the NATURALIST as the successive parts appeared. We have to add, on this occasion, our renewed commendation of the care and de- tail with which Dr. Fritsch continues to develop the subject, and our praise for the admirable plates which accompany the text. The species treated of are those which belong to the larger forms of the Rhachitomi, together with some of the intermediate types, such as the Dendrerpetonide. Of the greatest interest are two new genera of the order Embolomeri, Chelydosaurus and Sphe- nosaurus, where the additional vertebral centrum, entire in the type of the order (Cricotus), is divided into three segments, two lateral and an inferior. This is a curious discovery, especially as Sphenosaurus has hitherto been regarded as a reptile.’ It also has an important bearing on the value of the order Embolomeri, which Dr. Fritsch is disposed (p. 4) to question. He thinks that the embolomerous vertebral structure is confined to the caudal region in the genus Cricotus, although I have figured it in the lumbar and cervical region of that genus, and described it as found in the dorsal* region. Dr. Fritsch reached this conclusion because he finds that in Archegosaurus the caudal region is em- bolomerous, and the dorsal region rhachitomous, His discovery of the persistence of the embolomerous condition in the dorsal ion of Chelydosaurus and Spl might have suggested to him the correctness of my observations on Cricotus. I add here that in Eryops, in which the dorsal vertebrz are rhachito- mous, the caudal vertebre are not embolomerous. So Archego- saurus stands alone in this respect. This determination of the characters of Archegosaurus by Dr. Fritsch is very useful to in palzontologists, as it has hitherto been very imperfect- ly described. I have stated that there are vertebre of this type 1 Fauna der Gaskohle in d. Kalksteinen d. Permformation Böhm Von Dr. An- ton Fritsch, B. 11, Heft 1; Praag, 1885.

As they agree exactly with Dr. Fritsch’s figures of Archegosau- rus, it is difficult to perceive why he denies the accuracy of my statement in the matter (p. 15). Both the authors here reviewed have evidently been more or his. characters in defining his genera. We cannot but think that the publication of this system was a misfortune to the progress of the subject. The characters of the relative position of the eyes and nostrils and the outline of the skull are certainly only specific characters, and the veriest tyro in the study of recent Batrachia would not use them for generic characters, still less for family characters, as is done by Mr. Miall ydekker’s paper introduces an undoubted member of the order Rhachitomi to the Indian Permian fauna, and devotes his usual care to the description and illustration of it. Unfortunately the skull of the single specimen at his disposal has lost the bones of its superior face, so that many of the characters of the species given the barbarous name Gwandanosaurus, is not so defined as to be distinguishable from some of those already known. In view of its possibly turning out to be identical with some of these, Dr. Lydekker remarks that he relies on the spirit of the following rule of the International Nae en Congress of Bologna “in favor of his own name,” z.¢., “In future for specific names priority shall not be irrevocably reh unless the species shall ave been not only described but figured.” This is a doctrine ing illustrations unnecessary, are much more inportant than they to the real advancement of science. Examples of the disregard of the law of priority in this paper are seen in the proposition that the name Actinodontide super- sede Eryopidæ of prior date, and the use of the term hypocen- trum for intercentrum of prior date. This we hold to be simply creating confusion, and causing much inconvenience to the stu- dent! Moreover, Dr. Lydekker has not read the paper which he quotes. He states (p. 7) that the intercentrum of Cope is the pleurocentrum of Gaudry, and the centrum of Cope is the hypo- centrum of Gaudry. The fact is the reverse. The intercentrum was renamed hypocentrum by Gaudry, and the centrum of Cope 1 The same untenable method is evinced in Dr. Lydekker’s mnl of the name Creodonta ( wet Lege the proposition to use in its stead the inconvenient expression “Carnivora primigenia” (Catalogue of Fossil Mammalia in British Museum, 1885, p. 20). 594 General Notes.

THE GENERA OF THE Dinocerata.—Professor Marsh’s work on this order of mammals, just ely supplies some important data as to the characters of some of the species described by him. I can now discriminate more clearly the generic characters, which are, I think, as follows : Four bilobed symphyseal teeth on each side; inferior canine vies not enlarged; in- ferior premolars three xolophodon Cope. Four symphyseal teeth on each side, at least some of which are not bilobe d; infe- rior canine larger mes incisors; four inferior premolars, the first ae second separa. ted by a diastema. ......0+ Bathyopsis Cope.

No inferior canines or incisors; three inferior premolars,......... Tetheopsis Cope. Most of the known species belong to Loxolophodon, each of the remaining four genera having but one species each. Loxolo- phodon includes as synonymes the names Dinoceras and Tino- ceras Marsh, which were proposed as nomina nuda after Loxolo- phodon, and were not characterized until several years later. It is uncertain whether Eobasileus, which was proposed and defined at about the same.time as Loxolophodon i is distinct from it or not. Octotomus is also a synonyme. Ditetrodon is established on Uintatherium segne Marsh, and Tetheopsis on Tinoceras sten- ops Marsh —E£, D. Cope. THE UNITED STATES GEOLOGICAL Survey,—In an article upon the organization and plan of the United States Geological Survey, published in the American Fournal of Science, Mr. J. W. Powell states that, where the topography and geology are simple, as in the prairies and great plains, the sheets of the United States sur- vey map are made on a scale of 1—250,000, or about four miles to the inch; while farther west, where both structure and topog- raphy are more complex, special districts are made to twice this scale, and important mining districts are drawn much larger. In the less densely populated portions of the eastern part of the United States, a scale of {-125,000 is used, but the more densely populated portions are drawn to twice this scale, or about one mile to the inch. The whole of the United States and Alaska _ will, upon this plan, require not ee than 2600 sheets; besides ci Fy Tao OF - THE Sy eae PerIop.—The recent discov- _ eries of Mr. Charles Brougniart in the insect fauna of Commen- 1885.] Geology and Paleontology. 595 American types need to be brought into their proper place, I have thought best to offer a brief synopsis of those Carboniferous forms heretofore discovered (with a few additional ones from this continent), which may be referred to the ancient Phasmida Among them will be found nearly all the species heretofore re- ferred to the Termitina from the European coal measures, for a careful study shows that the white ants were not at all represented in Paleozoic times, so far as the forms yet discovered show.

Brackebusch upon the geology of the province of Jujuy. Except for the in- formation gathered in 1876 by Lorentz and Hyeronimus, an some notes on the primordial fauna by E. Kayser, this northern part of the Argentine Republic has hitherto been geologically unknown. The south-eastern part of the province, near the Ver- mejo, is comparatively low, though even here the Sierra of St. Barbara rises west of the Rio S. Franciso to 3000 meters. e larger central and western portion is entirely a mountain land, range after range rising to heights of from 4500 to 5500 meters, separated by valleys, some of which are basin-like depressions, km broad. This western part is sterile, while the east is . highly fertile. The mountains of Jujuy have a closer relation to the Bolivian plateau than to the chains of the center and west of the Argentine provinces. The most western chains (Sierras de la Puna) consist principally of clay slates, alternating with grau- wacke, and, save in one locality, are without fossils. The easterly Sierra de Chuni consists of slates, grauwacke and sandstones, the last rich in Silurian fossils, graptolites, trilobites, cephalopods and brachiopods. Newer formations occur in the basins between the mountains, gypsum-bearing sandstone, dolomite, limestone, oolite and bituminous shales, etc. Fish andi t ins have been foun in the Sierra St. Barbara. Strata corresponding to those which 596 General Notes. ; [June, d'Orbigny referred to the triassic in Bolivia are by Brackebusch placed in the Wealden or Neocomian. In these Mesozoic strata occur many petroleum springs, and throughout Jujuy and Salta, in Bolivia, and probably below the diluvium of the Gran Chaco, ‘the character of the formation is such that Brackebusch styles it the “ petroliferous formation.” A small basin near Jujuy has Post-tertiary strata, with beds of lignite and mastodon remains. Eruptive rocks occur in many localities, and gold ore is found in the beds of the streams which flow from the Sierra, Cabalonga. Part 1 of the “ Grand Atlas of the Second Geological Survey of Pennsylvania,” with fifty sheets imperial folio, has been pub- lished at Harrisburg. The two “ Prix Vaillant” of the Acad- emie des Sciences de Paris have been given, the first to M. Gustave Cotteau, for his researches among fossil echinoderms ; the second to M.

The results of the researches of M. Riviere have been published in a work entitled “ L’antiquite de l’homme dans les Alpes Mari- times.” M.

Later, the application of Reusch’s method of forming the so-called fracture figures (‘Schlagfiguren’’) showed that the same was also true of erythrite, vivianite, hydrar- gillite, brucite, potassium ferrocyanide, uranium mica and even apophyllite and topaz. In the case of the two latter minerals, it was necessary to use a diamond-pointed instrument to make the impression.” Most interesting, however, are these “gleitflachen” in calcite, where they stand in the closest relation to the twinning planes. As “ structure planes” Migge designates all those along effected. Of ea in calcite R is the true cleavage plane (“ Spal- tungsflāche ”); —1%4R the slipping plane (“ Gleitfläche ”), while parallel to %P2 and oR parting readily takes place under press- ure in the proper direction (“ Reissflächen ”).

A oR-face takes the position of —2R, parallel to which a parting has also been observed by Haidinger and Tschermak. Thus all the structure planes retain the same positions, although they exchange them among themselves. It is significant that all these planes, except œP2, which is a plane of symmetry, have been observed as twin- ning planes for calcite The great ease with which by slight pressure the molecules of calcite may be pushed into twinning position parallel — 4R suggests a similar origin for the lamellar twinning of many silicates, especially as this is often observed to be most developed w where the pressure has been greatest.

A similar structure is frequent in the Graves Mt. rutile parallel oP. In these cases also, as with the silicates, the nature of the material prevented the artificial production of the lamella. In some minerals where no alteration of molecular arrangement could be brought about by pressure, this result was accomplished by heat. By a sufficient increase of temperature twinning lamella were seen to be devel- oped in anhydrite, cryolite’ and leadhillite,t while thenardite was rendered optically uniaxial, as Mallard had showed was the case ing it as a separate species.

The same reason is assigned for uniaxial minerals exhibiting a biaxial character. W. Voigt,' of Gottingen, has developed mathematically a theory to account for the peculiar interference figures exhibited by cached pleochroic (idiocyclophanic) crystals recently described by tin (Zeitschr. f. Kryst., 11, p. 449). Tue FELDSPARS.—Professor Des Cloizeaux, of Paris, has just published at Tours a valuable memoir of ninety-two pages, entitled “Oligoclases et Andésine,” being an enlargement of his former paper, “ Nouvelles recherches sur les propriétés optiques des oligo- clases,” which appeared in 1880, and a direct continuation of his still more recent studies on albite? (vid. NATURALIST, 1884, p. 184). The latter paper describes thirty-four specimens from different localities, of which ten are American (Mineral Hill, Pa., Moriah, , Middletown, Ct., and Canada). In the present communi- cation the number of o oligoclase specimens examined has been in- creased from forty-four to sixty-six. These are divided into the following four classes : Ist. Anomalous oligoclase or oligoclase-albite. —The surface per- pendicular to the plane of the optical axes truncates the acute edge P:M., making with P an angle of 93°.

The third-class includes sixteen speci- mens, mostly from Scandinavia, and the fourth-class nineteen specimens, of which one was from Chateau Richer in Canada. | The remaining eleven specimens examined by the author did not yield altogether satisfactory results. ery interesting facts regarding the relations between the monoclinic and triclinic feldspars have been obtained by Dr. Forst- ner of Strassburg, through his studies of material from the island of Pantellaria.‘ He finds that both the potash (orthoclase) mole- cule and the soda (albite) molecule undoubtedly possess a stable and unstable modification, the former being for orthoclase in the monoclinic, the latter in the triclinic system (microcline), while exactly the reverse is the case for albite. It has long been known that some varieties of orthoclase, especially sanidine, contain a very considerable amount of soda and the existence of the tri- clinic form of the potash molecule has been universally acknowl- edged since the classic investigations of Des Cloizeaux? Först- ner finds on Pantellaria that a monoclinic feldspar containing 2.1 albite molecules to every molecule or orthoclase occurs as a con- stituent of a certain rhyolite (Cala Porticello and Bagno dell’ acqua). This he calls “ Natronorthoclase.” It is very similar both in composition and structure to that described by Brogger® and Miigge* from Norway, and by Klein, from Hohen Hagen, near ttingen. Even more common on Pantellaria, as a constitu- ent of the augite andesite and pantellarite (a dacite character- ized by a peculiar triclinic amphibole called “ Cossyrite®”) is a cline. Very remarkable is the ease with which these intermediate members—natron-orthoclase and albite-microcline—can be trans- ferred by artificial means from one modification to the other. Some albite-microcline (Cuddia Mida) shows,even bya temperature of 86°-115° C., a disappearance of its twinning lamellz and by other optical changes is plainly seen to pass from the triclinic to the monoclinic system. The oligoclase-microcline from Mt. Gibele, on the other hand, remained unchanged even at 500° C. Most feldspars of this series changed, back to their original triclinic form when the temperature was again reduced, except when it had been raised as high as 500°, in which case the change to the monoclinic form was as a rule permanent. The natron-orthoclase showed no change while being heated, but on being cooled from S aai se hie, VIII, 1883, pp. 125-202; 1x, 1884, pp. 333-352- * Comptes rendus, 1876, p. 885. 3 Die silurisc} Etagen 2 und 3 im Kristi Lr t, etc, ; Kristiania, 1882, pp. 258- 262; 293-307. eG: g Peg Jahrbuch für Min., ete., 1881, 11, 106. š -6 Zeitschrift i für Krystallographie, v, 348. 1885.| Botany. 601 a temperature of 264° C., it passed from the monoclinic to the triclinic modification, having a distinct system of twinning lamella and an inclined extinction of 2° against the cleavage lines on oP. The same feldspar was also found to undergo a like alteration when subjected to pressure, thus experimentally proving the sug- gestion of Van Werveke! that many plagioclase crystals owed their twinning striation to the pressure to which they had been sub- jected in rocks. HyYPERSTHENE-BASALT.—A correction should be made to the statement in the Petrographical Notes (NATuRALIST, April, 1885, p. 395), that Mr. J. S. Diller was the discoverer of the new rock type hypersthene-basalt. This rock was described by Messrs. Hague and Iddings in 1883,? in their Note on volcanoes of Northern California, Oregon and Washington Territory, and again in 1884%, in their Notes on the volcanic rocks of the Great basin. It is, however, here spoken of as olivine-bearing hypers- thene andesite, or as hypersthene-bearing, basalt. These authors regard the hypersthene and olivine as playing complementary réles in the lavas, 7. e., one being a singulosilicate and the other the corresponding bisilicate ; in case a basalt grows slightly more acid the hypersthene replaces the olivine, which therefore diminishes in quantity as the other increases. In this way hypersthene- basalt may be regarded as a connecting link between basalt and hypersthene-andesite.

E STUDY OF THE LIVERWORTS IN NORTH AMERICA.—AS one of the results of the one-sidedness of the usual teaching of botany in this country, whereby it is almost entirely restricted to the flowering plants and “vascular cryptogams,” we find a most unequal distribution of workers throughout the various botanical fields. We have any quantity of “phanerogamists,” but though the cryptogamic fields bear a plenteous harvest, the laborers are few, and year by year as the scattered workers are cut off by death, there are few among the younger ones to take their places. There must be something faulty in the instruction given by our botanical teachers in the many colleges and universities in this country. The results would indicate that in too many cases the kingdom of plants is supposed to come to an end just a little way beyond the boundary of the phanerogams These thoughts are suggested by a little book recently brought out by Dr. L. M. Underwood, under the modest title of a Descriptive Catalogue of the North American Hepatic North of Mexico. In a prefatory note the author says, “The study of hepatica is attended with much iia for several reasons, among which may be named the following: 1. These plants are very largely neglected by collectors. 2. The literature on the subject is rare and inaccessible. 3- Most of our public and college libraries contain little or no _ literature rues this subject. 4. Many of the species described as new by American writers are not represented in any American collection. It is to be hoped that the purpose of the book as stated by the author “to relieve in part these difficulties, and to stimulate a more complete collection of Hepaticz ” may be realized. _ Tuming to the body of the book we find a few pages devoted _ to the general characters of has liverworts, time of collecting, a ae ution ti characters bibliography, oo a arama of the Back being filled with the dive cl 4 $ 1885. ] Botany. 605 As to the time for collecting, the author says: “The hepatics should be collected for preservation and study when in fruit, if this be possible, and this condition occurs at different seasons in the various species ; some bear fruit in late autumn, some in early spring, some in midsummer ; in short, there is scarcely any sea- son of the year, even winter, that will not find some form in fruit, yet the period from October to May may include the larger num- ber of species for the cool temperate regions of America. Many species have never been found in fruit, and possibly never produce fruit, so it will be advisable to collect all species whether in fruit or not, for otherwise these less known forms may be neglected.” Comparing the systematic portion of this work with that of Sullivant, which was published in Gray’s Manual, twenty-five years ago or thereabouts, we find a very considerable increase in the number of genera and species. k Genera.

Botany AT SALEM.—The following extract from Professor Robinson’s annual report of the work of the Peabody Academy of Science (the old home of the NATURALIST) shows a commend- able activity in its botanical department during the year 1884: “ In the department of botany a great improvement has been made. As various collections were from time to time arranged of white wood, containing ninety-six compartments, has been placed in the lecture-room, in which all the Essex county collec- tions and the general reference collection from North America have been arranged. Other collections have also been placed in the lecture-room, so that now the herbarium is in a dry and pleasant room-where it can be easily referred to by those in charge. of it and by students who desire to consult it. “The academy now owns a very good collection of botanical reference books, and two microscopes, which, under proper restric- tions, are placed at the disposal of any persons desiring to com- species at the museum. The herbarium is by far the best in the county; it is centrally and conveniently situated, and has 606 General Notes. [June, been frequently consulted through the year by students in this department of study. The special work on this collection has been the arrangement ' of the Algz, of which there were a large number of specimens. BotanicaL News.—For some time occasional papers have ap- peared in the Amer. Mo. Micr. Jour., attempting to throw doubts upon the prevailing views as to the mode of fertilization in flowering plants. Microscopical preparations by Mr. J. Kruttschnitt, have been sent out for examination, with the intention of proving the new view. The editor of the Botanical Gazette in the January num- ber devotes about a page to an indignant denunciation of the whole matter. In the January Jour. N. Y. Micr. Society, Dr. N Britton devotes ten pages to criticisms of Mr. Kruttschnitt’s s papers and preparations. He closes by saying, “ The fact of fail- ure on the part of one, or indeed, of several persons, to discover a pollen tube in contact with the embryo-sac of an ovule, can, it seems to me, have no weight when viewed in connection with the fact that so many able investigators have often and undeniably seen such contact.” The friends of this wild theory need no longer complain of its being ignored by botanists! AH. Curtiss, of Jacksonville, Florida, has prepared two series of wood specimens, including seventy-five species in each. Each specimen shows heartwood, sapwood and bark, and is accompa- nied by a printed label. The low price at which they are sold ($15 per single single series, or $25 for the two) ought to place them in many a botanical cabinet. An important pamphlet On the establishment of a Botanical Garden and Arboretum in Mon- treal, has been issued recently by the Montreal Horticultural So- ciety. It gives some valuable statistics as to the botanic gardens of the world, and sets forth their scientific and practical value. It is mainly from the pen of Professor Penhallow. One of the aye valuable catalogues issued by the exhibitors at the New Or- ans Exposition is that enumerating the articles forwarded from the Island of Jamaica, the work of Mr. D. Morris. It is particu- larly interesting as containing classified lists of plants and plant products. The collection of Florida woods in the gs, a is one of the finest on exhibition. It was prepared, assured, by A. H. Curtiss, of Jacksonville. The eoleo of California plants shown by J. G.

Ritey’s ENTOMOLOGICAL REPORT FoR 1884.—The last report of the entomologist of the Department of Agriculture fills about 150 closely printed pages, with ten excellent plates and a full index. In practical as well as scientific value and in the variety of subjects treated, it is not inferior to its predecessors. The cabbage cut-worms are described at length and well illustrated, as well asa number of other insects. destructive to this plant. Efforts have been made to introduce and colonize the European ichneumon parasite (Apanteles glomeratus) of the imported cab- bage worm, and thus far the experiment has been successful. The report contains also interesting life-histories of the Amer- ican Cimbex, which has in Washington injured the willow, and lengthy notices are given of the Southern buffalo gnat, the angou- mois grain moth, the cottony maple scale, the cranberry fruit worm, the larger wheat straw Isosoma, etc. Much attention is paid to the use of remedies. The reports of the special agents comprise those of Mr. Hub- bard on the rust of the orange, Professor Packard’s on the causes of destruction of the evergreen trees of Northern New ‘cranberry; and Mr. Bruner’s on the Rocky mountain locust, etc., in Nebraska. Asasample of the excellent illustrations is Pl. xvii, which represents the cottony maple scale, with its eggs and larva (Fig. 1), the leaf with male scales (Fig. 2), the female scales (Fig. 3), and in Fig. 4 the adult females with the wooly egg-mass as seen late in the spring. Latzet’s Myriopopa oF Avustro-HuncariA.—This admirable work bears all the marks of faithful and exhaustive labor, whether we consider the text or plates. The descriptions of the orders, suborders, families, genera as well as species are given in detail, especially those of the orders and genera, and the work will thus be of special value to American students. This part contains monographs of the Symphyla, Pauropoda. and Diplopoda. Personally the reviewer does not regard the Symphyla, represented by Scolopendrella, as genuine myriopods, but none the less would he cordially welcome the work which 608 General Notes.

However, he regards the Chilognatha as the second suborder of Diplopoda, proposing two new suborders, first the Pselaphognatha (for the Polyxenidze), and third and lastly the Colobognatha for the Polyzonidz, all the other diplopods being placed ‘under the Chilognatha. The Lysiopetalide, as limited by American authors, is dismem- bered, all except a TIF being referred to the family Chor- deumi a, whereas he should regard the two groups as sub-fami- lies of Newport's Bec Lysiopetalinaz, established in 1844. The American genera Scoterpes, and Zygonopus are considered as identical, a view we at first entertained, but afterwards abandoned, so great is the difference in the sixth pair of legs and the male genital armature. Trichopetalum is regarded as identical with Craspedosoma and perhaps partly with Chordeuma. TROUESSART AND Mecnin’s Sarcorptip Mires.—The first part - Of Trouessart’s “ Les sarcoptides plumicoles ou Analgésinés,” em- braces an account of Pterolichus and its allies, worked out with the aid of M. P. Megnin. These mites live on the plumage of birds, feeding upon the oily substance excreted by the skin, and not annoying the birds themselves ; they are not then true para- sites, but simply commensals. Several new genera and many new species are described, and the present part is illustrated by about twenty-five wood-cuts. About 1 150 species will be described. _ They have been taken from birds brought from different parts of the world, and it has been found that the same species of the sub- family lives on all species of birds belonging to one family. They are exposed to much variation, particularly Fregana anatina. The great variability of this species is readily explained by the parasite habits and by special condition of the medium, of food, habitat and climate. The work promises to be of much value to American students, for the subject here is almost unworked.

It seems to us that Mr. Smith in this essay fails to take a comprehensive view of the group ; his families are sub-groups, and to base families wholly on the venation is carrying matters to an extreme ; the venation in this family seems to us to be mainly useful in defining genera. Mr. Smith is led to throw Endryas out of the family, whereas by its larval, pupal and head and trunk characters it is a true Zyg- enida, the characters Smith uses are, we think, superficial. The two closing articles of the first number of the volume are by Dr. Horn, on the North American species of Cryptobium and Studies among the Meloidze. Interesting notes on oviposition in Agrion and insect migration appear in the Extomologists’ Monthly Magazine for February. Mr. T. L. Casey’s Contributions to the descriptive and systematic Coleopterology of North America con- tains carefully prepared and lengthy descriptions of new genera and species of American beetles which will be of permanent value, We trust that the time for sub-lined descriptions of Coleoptera has gone by.——At a meeting of the Entomological Society of London, held Feb. 4, Mr. W. L. Distant exhibited a series of wings of Indian butterflies, showing the differences between broods of the same insect in the wet and dry seasons respectively, which had hitherto been generally regarded as distinct species. Professor Packard desires specimens of Nola and of the Notodontians, with aview to preparing a revision of these groups of Bombycide. L. R. Meyer Dir, a well known Swiss: entomologist, died at Zurich, March 2d, aged 73. On November 28th, G. A. Kefer- stein died at Erfurt, aged 91, at the time of his death the oldest entomologist in Europe. ZOOLOGY. . DISTRIBUTION OF COLOR IN THE ANIMAL Kincpom.—L. Came- rano discusses this subject at length. Colors may be arranged in accordance with the frequency of their occurrence, thus: (1) Brown; (2) black; (3) yellow, grey and white; (4) red; (5) green; (6) blue; (7) violet. Black, brown and grey are more common in Vertebrata than in Arthropoda, while red and yellow met with, but they occur in all groups of the animal kingdom. White is irregularly distributed, but more characteristic of aquatic animals. The colors of animals bear a relation to the mediums in which they live; parasites are less varied in color than free-living animals. Aquatic animals are commonly more evenly and less brilliantly colored than land animals; pelagic animals, as might be predicted from their transparency, are not strikingly colored. Among birds the strongest flyers are most soberly tinted. Of in- habitants of the sea, those that live among Algæ are more vividly 610 General Notes. [ June, colored than those which live under stones or on a sandy bottom; similarly land animals that inhabit forests are on the whole more conspicuous for their bright coloration than animals which live in deserts. There is no relation between the color of an animal and its coloration, In very dry climates the colors appear to be darker, while the reverse is the case in damp climates. The various zoological regions of the earth are characterized by a certain dominant range of color in their inhabitants ; grey, white, yellow and black char- acterize the animals of the palzarctic region; yellow and brown those of the Ethiopian; green and red are the prevailing tints of the neotropical; red and yellow, of the Indian region. Australia is distinguished from the rest by the great abundance of black animals, In a given group of animals the larger species are usually more uniformly colored than the smaller. Sexual colors bear a general correspondence to the development of the animal ; the males are mostly more brilliantly colored; in many cases, however, where the females are larger and stronger than the males, the former show the more brilliant coloration. Young animals are often differently colored to the adults, their colors are generally more like those of the adult female. The young of several species that are most dissimiliar in their colors, when adult are often hardly distinguishable in this respect—/ournal of the Royal Microscopical ety, February, 1885. LIFE-HISTORY OF STENTOR CÆRULEUS.— Professor G. W. Worces- ter gives a detailed description of the development and life-history of Stentor ceruleus, which can hardly be satisfactorily abstracted. When first observed it appeared a motionless, intensely blue mass, containing what seemed to be a row of internal vacuoles, which later proved to be the moniliform endoplast of the mature infuso- rian. A larger vacuole was observed that subsequently became the mouth. The mass slowly changed its form, developing cilia at each extremity. The cilia eventually disappeared from one ; the shape was constantly varied, and in a little less than two hours it had put on the mature form, and was swimming very a rapidly. Conjugation with another specimen was then observed, each fastening itself by its posterior end to some object, their backs meeting, when they would roll over each other till their anterior extremities met. Conjugation lasted some moments when the : cimens separated and swam away. The individual 1885. ] Zoology. 611 observed lost its bluish tint and became of a bronze color. About an hour and a half after the conjugation it stopped suddenly, assumed a flat spread-out condition, whilst at the same time large vacuoles appeared throughout its entire mass. In appearance it ` was amoeba-like, and after a time small masses became detached and immediately assumed a globular form. The detachment of masses whilst in this amceba-like stage in other specimens was witnessed, as also their development into mature forms. The main mass would in some instances disintegrate after por- tions had been detached to form new individuals, nearly all the production by the formation of internal embryos was also observed, likewise the rarer method of fission proper. Professor Worcester considers the primitive form to be that of a sphere, and that the series of later forms assumed are so taken on by the creature in order to adapt itself more fully to its environ- ment. The posterior end would seem to be appended more for locomotion and for the purpose of fixing itself. Conjugation must in some way play an important part in the re-arranging of the protoplasm.— Yournal of the Royal Microscopical Society, De- cember, 1884. A Nervous System IN Sroxces.—Dr. R. v. Lendenfeld de- scribes the presence of nervous elements and ganglion cells in the heteroccelous sponges, In the Sycones the walls of the pores contain groups of spindle-shaped cells, mesodermal in origin, which are frequently connected with branched cells, apparently of tinuously grown to the mantle, the organic substance of the mother-of-pearl layer forms a net-work.

It has been successively studied by Steno, Lorenzini, Petit, Redi, Leydig and Schulze, the latter of whom have indicated the true path to be followed for the discovery of the functions of this line, whilst they have almost completed the investigation of its anatomy. M. de Séde, in a thesis recently maintained before the Faculty of Sciences at Paris, and reproduced in Cosmos les Mondes, gave an account of certain interesting experiments made for the purpose of elucidating the physiological functions of this curious organ. The fishes selected for the experiment were first submitted to the action of an anesthetic, and then underwent the operation of re-section of the lateral nerve, which excited no reflex action due to pain. When resuscitated the subjects were left at rest ina large bowl, and some days afterwards they were placed in a vast aquarium where everything is so arranged that a fish desirous of circulating freely must make use of all its tactile resources and means of guidance. Under these conditions it was observed that the fishes which had been operated upon moved only with great caution, and were almost always the last to arrive at the distribu- tion of food. Thus it appears that a fish able to make use of its eyes, but deprived of its lateral line, experiences a certain diffi- culty in finding its way. __M. G. de Séde next sought to ascertain how a fish would act if it retained the use of its lateral line, but was deprived of sight. Two perches were blinded by removal of the eye-ball. There remained to them, then, for guidance, merely. the general sensi- bility of the integuments and the special impressionability of the lateral apparatus in question. These organs. acquire in a short time a great delicacy, for the two perches, when placed in the general aquarium, were soon able so guide themselves without any difficulty. : But the question now arises as to what part of this steering power belongs to the general sensibility, and what to this lateral line? Further experiments solved this problem. A barbel was blinded, and, by way of extra precaution, its fila- ments were amputated. Subsequently its lateral nerve was severed. As long as this fish—even though deprived of its eyes and beard—retained the lateral nerve it guided itself easily ; but ~ as soon as this nerve was severed, it remained persistently mo- — 3 Lastly, a perch, blinded and deprived of its lateral line on one 1885.] Zoology. 613 side only, was placed in the labyrinthine aquarium. It contrived to keep the non-mutilated side turned towards any obstacle. These experiments leave no doubt as to the function of the lateral line. It is a very delicate organ of touch, adapted to the requirements of an aquatic life. It is sensitive to the faintest movement of the water, takes cognizance of the slightest displace- ments, and gives fishes continual information on the state of the medium in which they live. ZooLocicaL News.— Vermes.—Mr. W. Bateson has contributed to the Quart. Jour. Micros. Sci., an account of the early stages of the development of examples of Balanoglossus found at Hampton, Va. The adults agree very closely with B. kowalevskii of Agassiz, but as the development differs, the species cannot be identified. At no stage has the larva any superficial resemblance whatever to a Tornaria, such as is described by Agassiz as occurring in the development of B. kowalevskii. The eggsare elliptical and opaque, are fertilized outside of the body ; divide into two, segment regu- larly and then form a hollow blastophore, enclosing a segmen- tation cavity. The gastrula is formed by invagination, the blasto- pore closes completely, a posterior transverse ring of cilia, forms, and the body elongates and becomes marked out into regions. The mouth is a small pore in the ventral middle line of the ante- rior transverse groove; and the nervous system is formed by a segregation of epiblastic cells in the dorsal middle line of the collar, forming a cord lying immediately beneath the skin. The larva is always opaque, and creeps about in the muddy sand when hatched. Celenterates—According to R. von Lendenfeld, the Crambessa mosaica in Port Jackson is brown, while that of Port Philip is deep blue. The difference is caused by the presence of Zoanthel- læ, parasitic algae which may possibly be young stages of Lami- Narians, in the Sydney variety, which Mr. Lendenfeld names Crambessa mosaica symbiotica, because it has become associated symbiotically with an alga, and thus differs from the Melbourne form as lichens differ from fungi. Should the variety not be able to live without its parasite, it would be a new species. Huxley, in 1845, does not notice the brown color, and all previous au- thors, though they have collected the species near Sydney, de- scribe it as varying in color from blue to gray. . Our author asks whether the change has taken place since 1845 ? Batrachians and Reptiles —Professor E. D. Cope as one of the results of his studies on the batrachian and reptilian fauna of Mexico and Central America, which had been prosecuted by the use of material mainly placed at his disposal by the Smithsonian Institution, states that the total number of species described up to date is six hundred and ten, which is described as follows : VOL, XIX.—NO.

Mr. Caldwell writes that Platy- pus embryos are quite easy to get and he cannot understand why they were not obtained before. He has thirty blacks with him and they have found 500 Echidna in six weeks. From a study of the cerebral convolutions of the Carnivora and Pinnepedia, Professor St. Geo. Mivart gives additional reasons for the three- fold division of the forms into Cynoidea, AZluroidea and Arc- toidea., In a paper recently read before the Linnean Society, he called attention to the universal tendency among the Arctoidea to the definition of a distinct and conspicuous lozenge-shaped patch of brain substance defined by the crucial and pre-crucial sulci. This condition does not occur in any non-Arctoid carnivore, but is found in Otaria gillespit and Phoca vitulina, where it is small and much hidden. He adduced this fact as an important argument in favor of the view that the Pinnipedia were evolved from some Arctoid, probably Ursine, form of land carnivore. The brains of ` Naudinia, Galidia, Crytoprocta, Bassaricyon, Mellivora, Galictis and Grisonia, were for the first time described in detail. The Viverrina, judged by the cerebral characters, formed a very dis- tinct group among the Æluroids. EMBRYOLOGY.! On THE FORMATION OF THE EMBRYONIC AXIS OF THE TELEOS- TEAN EMBRYO BY THE CONCRESCENCE OF THE RIM OF THE BLASTO- DERM.—During the season of 1881, I had an opportunity to study part of the developmental: history of E/acate canadus at Cherry- stone, Virginia. But unfortunately the lot of ova investigated by me did not develop to the period of hatching, but only passed a little beyond the stage when the blastoderm closes. “As I have elsewhere to the very remarkable condition of affairs ob- _ served by me just previous to the closure of the blastoderm in ~ this species, and not being likely to soon again have an opportu- ~ nity to study the same form, I will now describe and figure what ` Edited by JoHN A, RYDER, Smithsonian Institution, Washington, D.

This species hatches in 24 to 36 hours. The accompanying figure represents the embryo lying on the surface of the vitellus, and is represented as foreshortened, anterior- ly the optic lobes, of of, on the other side of the vitellus show through the transparent yolk. e embryonic axis shows the seg- ments or somites, 7, distinctly developed, but it is very remarkable that the segmenta- tion does not end at the point where the axis of the embryo so far formed ends. The right and left limbs of the blastodermic rim form a X-shaped mass, together wit the embryonic axis anteriorly, but unlike any other normal teleostean embryo both these limbs of the rim are distinctly seg- ‘mented for some distance as at m. Just within the yolk and a little in front of the yolk-blastopore, which runs forward into the acute angle formed by the limbs of the blastodermic rim, 47, lies the'large oil drop, o. A lozenge-shaped mass of cells lies in the acute angle of the 4-shaped terminal part of the embryo, which appears to contain or overlie Kupffer’s vesicle, Av, and what was assumed to be the chorda, c, at the time the observation was made, but of the certainty of this determination I am not at present satisfied. I was enabled to sketch this and a slightly more advanced stage several times, and as already stated found the same condition in a number of embryos, which seemed to be developing normally. Four other sketches show that the blastoderm finally closes very much as in other teleostean embryos and that pronounced wrink- les radiate from the crater-like opening upon the yolk where the yolk-blastopore finally disappears. The conclusions of His and Rauber to the effect that the em- bryonic axis is formed by the gradual fusion from before back- wards of the inner edges or the lips of the yolk-blastopore, as it advances over the surface of the vitelline globe, are in this case evidently correct, though it must be admitted that the presence of the cellular mass between the limbs of the blastodermic rim _ where they join the embryonic axis is not a little puzzling.— Sohn A. Ryder. THE MODE OF FORMATION AND THE MORPHOLOGICAL VALUE OF THE Ecc or Nera anD Notonecta.—In the last number of the Zeitschr. fiir wissenschaftl. Zoölogie, 1885, XLI. (p. 311), Ludwig Will has an article on this subject and reaches the rather startling conclusion that an egg-cell is not necessarily a simple protoplast, but may, while on the way towards the development of the ripe 616 i General Notes. [Jure, egg, give rise to other cells. In fact, the central chromatin body of the primitive egg-cell, which he calls the 0d/ast, ejects a large number of chromatin pellets from its substance whic come the nuclei of the cells forming the egg-follicle. The conclu- sion at which Will arrives after reviewing the work of Fol, Roule, Sabatier, H. Ludwig, Balbiani and others, that in the ascidians, myriapods and insects, the nuclei of the follicular epithelium owe their origin to the primitive germinal nucleus or the ooblast, also holds good in respect to tha ova of birds and amphibians, is of great interest, and stands in sharp contrast to the old view that, the ovi-cell and epithelial ails of the follicle were both originally similar elements (germ-cells), but which have merely developed farther in widely differents ways. Will summarizes his results as follows: 1. The nuclei of the . oy ig epithelium are formed from the odblast. 2. The re- siduum of the ooblast becomes the germinative vesicle of the egg. 3: Ove which are without a follicular epithelial investment, as is the case in numerous groups of animals, are homologous only with the egg plus the follicular epithelium of the higher forms. 4. The egg of the Hemiptera is neither a cell nor an assemblage of cells, but the product of several cells. 5. The homological value of the eggs of different types is to be found in the fact that, in every case the ripe egg represents a germinal mass, in which are contained all the capabilities of future development, and which is the product of the activities of those cells which have shared in its construction.

The stage here figured displays the gland in the undifferentiated condition of the five-months’ human embryo, when the gland consists merely of an involution of the malpighian layer, ef’, filled by a solid core of more rounded cells, f which seem to become blended, at the lower end of the involution, with the Malpighian layer, the whole structure present- ing the appearance of a solid pyriform body jutting down into the mesoblast, m, and connected with the epidermis externally by a narrow pedicel. No signs of the outgrowth of the rudiments of acini from this pyriform body have yet appeared, but it would be inferred from the shape of the gland in the adults that these acini would be . most apt to first appear at the anterior and posterior sides of this body. The gland in the adult cetaceans is greatly elongated, flat and less than one-third as wide as long, reaching the enormous dimensions of ten feet in length, three feet in width and eight inches in thickness in the adult, gravid female of Balaenoptera sibbaldit. In the adult the gland is also traversed longitudinally by a spacious lacteal sinus, which is probably developed during the growth of the gland by a process of vacuolization. This sinus opens externally through the nipple by way of a single duct. The gland therefore probably belongs to that subdivision of mam- mary organs provided with pseudo-nipples, which are developed by the production of the edge of the embryonic mammary area into a tubular teat traversed by a single canal as in the cow, cer- . tain marsupials and rodents. In combination with the peculiar internal structure of the mam- mary gland of cetaceans, there is also an external teleological which they must be over a foot in length. It thus becomes evident that the mammary glands of cetaceans 618 General Notes. [June, develop at the start in much the same way as those of other Mam- malia, but that their evolution is complicated somewhat by the early appearance of the folds on either side of the mammary area, which grow upward to form the sides and roof of the fossz, which eventually enclose the nipples. The condition of the still earlier stages of the gland, judging from the general appearance of my sections, must be very similar to that observed in other mammals by Huss, Langer, Kölliker and others.— ohn A.

English- reading students are to be congratulated that two such competent workers as are the authors of these books have not only given accounts of our knowledge concerning bacteria, but have de- scribed in sufficient detail their experimental methods so that the laboratory student has but to follow directions in order to enter the field of bacteria research. Dr. Sternberg’s work includes a translation of Megnin’s Bac- teria, in which are described the morphology, classification and physiology of the germ fungi. But the laboratory student will find particularly valuable the translator’s original chapters on technology, germicides and antiseptics, bacteria in infectious dis- eases and bacteria in surgical lesions. Photo-micrographs form in part the illustrations of the book. To a worker the bibliogra- phy alone is more than worth the price of the book. Photo-micrographs and how to make them, by the same - author, is an elaborate and practical aid in this special branch of technology. "he work of Dr. Klein is a reprint of a series of articles which appeared first in the Practitioner. In addition to a clear account -of methods of research the author gives a copiously illustrated description of the forms of bacteria and a consideration of their relation to disease, Especially valuable are the criticisms on such views as Buchner’s concerning the transmutability of pathogenic and non-pathogenic forms. __ Vaso-MoToR Nerves.—Recherches Experimentales sur le Sys- teme Nerveux Vaso-moteur, Paris, Masson, 1884, pp. 338.

The innervation of the cutane- ous blood-vessels. 2. The dilator-function of the grand-sympa- thetic. 3. The vaso-dilator nerves of the external ear. 4. The vaso-dilator nerves of the inferior limbs. 5. Influence of the blood of asphyxia on the nervous mechanism of the circulation. The authors are convinced that the slow rhythmic contractions which small arteries, as those of the rabbit’s ear can be seen to undergo are not peristaltic, proceeding from the heart outwards, but in- volve the whole vessel simultaneously. In nearly all nerve trunks containing vaso-motor fibers, as the sciatic, the cutaneous and the sympathetic nerves, the vaso-motor filaments are of two kinds, vaso-dilator and vaso-constrictor. Efferent or centrifugal vaso- motor impuises, like ordinary motor discharges, all leave the spinal cord by way of the anterior spinal nerve roots; on the other hand all afferent or centripetal vaso-motor impulses enter the spinal cord through the posterior spinal nerve roots. The chemical condition of the blood determines largely the vaso- motor coordination between the vessels of the skin and of the viscera; asphyxia produces a dilatation of the vessels of the skin and a simultaneous contraction of those of the viscera. The direct action of dilator nerves traveling in the sympathetic can be demonstrated on the dog; stimulation of the sympathetic nerve in the neck causes flushing of the mouth and face on that side, The most valuable part of the work is that which considers the vaso-motor functions of the sympathetic ganglia. se tions indicate that these ganglia are automatic vaso-motor centers from which impulses go out to the muscular coats of the vessels and keep them in a state of tonic contraction. Dilation or, on the contrary, stronger contraction of the vessels is brought about indirectly by either stimulation or inhibition of the activity of the appropriate sympathetic ganglia through impulses reaching these ganglia from the spinal cord along either vaso-constrictor or vaso- dilator spinal nerves. The physiological classification of nerves announced by Borden and by Bichat is still supported by fact; namely, that the cerebro-spinal system presides over the functions of animal life and of relation; while the sympathetic system is concerned with the nutrition and vegetative life of the body. THE PHYSIOLOGICAL PURPOSE OF TURNING THE INCUBATING Hen’s Ecc.—The setting fowl frequently turns her eggs during incubation and when this process is carried on artifically, mechani- cal means must be adopted to effect the same purpose, M. Dareste finds that during the first week of artificial incubation eggs which are turned develop in essentially the same manner as those which are allowed to rest, but the monstrosities which have already been 620 General Notes. (June, formed in the latter soon take on an excessive development and in very few eggs which are allowed to remain unmoved during the whole period of incubation does the body cavity of the em- bryo become closed in. The cause of death in the unmoved eggs is, according to Dareste, the union by growth of the allantois with the egg-yolk which latter is thus prevented from becoming finally absorbed into the alimentary canal preliminary to the clos- ure of the body cavity. These adhesions of the allantois with the vitelline membrane lead to frequent rupture of the latter whose contents are thus largely lost to the embryo. Death of the chick in the unturned eggs usually occurs about the second week of incubation. When the eggs are turned over it is proba- ble that the position of the allantois upon the. yolk is shifted and this daily movement prevents adhesion between the two surfaces. Sixteen eggs were placed under the same conditions of artificial incubation, but eight were allowed to remain unmoved while the eight remaining were turned over twice a day. In the first set absorption of the yolk did not occur in any specimen, and all the embryos died in the course of the second or third week. In the second set, in six eggs the yolk was absorbed in the normal man- ner ; in a seventh, opened on the twenty-second day, the chick was alive and hearty and the yolk was being absorbed; in the eighth egg the chick was dead on the twentieth day and adhesion be- tween the allantois and yolk had prevented absorption of the lat- ter.— Comptes Rendus, 1884, p. 813. PSYCHOLOGY. PsycHIcAL REsEARCH.—At the Birmingham Midland Institute in November last, Mr. W. H. Myers, M.A., gave a lecture on “ Aims and Methods of Psychical Research.” The lecturer began by dwelling on the difficulty which the religious and scientific world experience in finding a common ground on which to meet, and pointed out that neither party had made a serious attempt to test the real value of those scattered indications of a psychical element in man which actual experience offers us. He explained that the object of the Society for Psychical Research was to sub- ject all these indications to a fair and unbiased examination on scientific lines. The experiments which had so far been tried consisted mainly in discovering persons of special sensitiveness, and subjecting them to certain influences, either of magnets, &c. (as in the experiments of Reichenbach, of Charcot), or hypnotic or mesmeric passes, or of mere expectant attention, this last pos- sibly inducing some influence at present unknown, as in so-called spiritualistic séances. In the lecturer’s view it was at present wholly premature to ascribe the last phenomena to the spirits of : the dead. Whatever in them was not due to mere fraud, must - wait for an explanation until the simpler phenomena connected : with sensitives were much better understood. The lecturer then 1885.] Fsychology. 621 explained the important discovery (due mainly to the society’s experiments, and to those of Professor Barrett in the first place) that mental pictures, thoughts, and sensations can in some cases be transferred from one person to another without contact, and without the agency of any of the recognized organs of sense. Some diagrams were here exhibited, representing simple outline drawings, which had been drawn by one person and reproduced by another person who had not seen them, but into whose mind their image had apparently been projected by a strong concentra- tion of thought. It was next shown that this theory of thought transference could be extended so as to explain many cases ot apparitions at death, &c., of which some examples were given. The lecturer insisted on the importance of a very large collection, and a very careful sifting, of first hand narratives of apparitions, govern such occurrences. The risks of error or exaggeration in these accounts were pointed out, and a warning was given against premature theorizing. The audience were requested to send to the secretary of the Society for Psychical Research, 14 Dean’s- yard, Westminster, any well-attested narratives of apparitions, &c., which they could collect, and especially the records of any experiments in thought-transference, &c. The lecturer concluded by stating that, although the evidence hitherto collected could not be said to amount to a proof of the survival of the soul after the death of the body, yet, so far as it went, it pointed in that direction, The evidence of the materialist theory was simply negative. That theory might be likened to a pyramid set on its apex: it was in a state of unstable equilibrium, and the smallest amount of positive evidence against it was sufficient to overturn it as a scientific theory. He drew a picture of the probable effect on human life and character if that great hope were to be raised into scientific certainty, and to become a pervading and dominant belief. Towards such great issues psychical research seemed to be tending, though the work must be minute and laborious, and the result must be slowly won.—£xglish Mechanic. A Doc ASHAMED OF THEFT.—A Baltimore gentleman owns a skye terrier which recently proved that it could feel ashamed of a dishonest act. At the time in question the gentleman was seated at his table. The little Skye saw a cutlet near the edge of the board, and yielded to the temptation to steal the meat. The cut- let was slyly seized and taken under the sofa. The gentleman pretended not to see the act of theft. But the conscience of the little terrier soon got the better of its hunger. It brought the cutlet back, laid it the feet of its master, hung its head in s and slunk away.—Philadelphia Call. We never personally knew “old Rove” to steal, but we were informed that he did once steal a piece of corned beef from a 622 General Notes.

He is no thief, however. We have not a doubt that early and persistent training of a bright dog, commencing with him when only a few weeks old, would cultivate the moral side of his nature, as his intellectual side is trained and developed by his intercourse with man. But beating never brings about any such results. The other evening we had turned “ Floss” out into the barn, and when he returned through the well room we have no doubt he gave us notice he wished for water; but we did not observe it. As we passed into the kitchen we turned to close the door after the dog, and there he stood upon the threshold, with such a look of intense yearning coupled with astonishment on his face, that we at once recognized his demand and supplied him with water. We thought that if there was not soul behind that look, the Creator of us all had surpassed Himself in lighting up the cold clay with the light of life.

ANTHROPOLOGY AT THE NEw Or eAns Exposition.— Every allusion to anthropology in New Orleans should begin with Dr. Joseph Jones, author of the Smithsonian contribution entitled the Stone graves of Tennessee: Since writing this contribution Dr, Jones has utilized his leisure from an arduous profession to con- tinue his researches in American archeology and in the various living problems which his position of president of the Board of Health brought before him. His splendid cabinet occupies one entire side of his house and contains nothing but the chef d’oeu- vres of American aboriginal art. Dr. Jones has in his possession a relic which will interest active archeologists. At Selzertown, fourteen miles from Nachez, is a celebrated mound mentioned by Sah ~ aa , covering about five acres of ground and about t The top of the mound is truncated and the sides indicate that the structure was formerly a regular teocalli erection.

In the New Orleans exposition almost every State and foreign government has exhibited something of the greatest interest to the anthropologist. From Maine we have basket and bark work of the Quoddy Indians. From, Ohio, Indiana, Illinois, Missouri Arkansas, Tennessee, North Carolina and a few other States there are very instructive private collections of antiquities. Louisiana exhibits one screen of the blow-tubes, basketry, bows and arrows and clothing of the Shetimasha Indians. Minnesota has a very large exhibit of sledges, birch bark work and Indian clothing. Nebraska, Dakota, Montana, Wyoming, New Mexico, Arizona, Nevada and California all exhibit the weapons, dress and imple- ments of their modern tribes. The Greely relief relics attract a great deal of attention, including a great many articles illustra- tive of Greenland Eskimo life. In the government space are two anthropological exhibits. That of the Bureau of Ethnology con- tains the excellent models of Pueblos by the Mindeleff brothers, two Indian busts executed by Achille Collin, a fine group of pot- teries from Chiriqui and from the pueblos, and the superb cabinet of old pueblo pottery belonging to Mr. Thomas Keam, who also displays a large case of Moqui dance paraphernalia. The Smithsonian exhibit contains a typical series of stone im- plements arranged by Dr. Charles Rau, and an educational series of modern Indian specimens covering the entire continent and including every category of savage culture The Mexican department cannot be $0 highly praised. Ina store room at’45 Chartres street Mr. Abbadiano, a Mexican artist, has on exhibition a series of gelatine casts of celebrated Mexican antiquities for which he asks eight thousand dollars. The work in these far surpasses in delicacy that of M. Charnay in the Lorillard collection. It comes out also by examination that M. Charnay did not take the impression of the whole sacri- ficial stone but a group or two here and there and multiplied them to get the fifteen groups around the stone. Now in Abbadiano’s cast of the whole stone it plainly appears that the second and fourth group to the left of the gutter contain women, and further- | more the ornaments on the persons of the captives are by no eva all alike. M. Abbadiano’s collection should find place in some great public institution, and it is to be hoped that he will succeed in placing it there. _ The Mexican department proper contains about 700 cases, in every one of which something can be seen illustrative either of the old civilization of that iiy or of those interesting survi- vals and transitions which throw light upon the history of man- kind.

The Mexi- can commission and government deserve the highest commenda- tion for this interesting feature of the exposition. Even their musical exhibit in the celebrated band contained such instruments as the bandolon, salteria and timpanis, new to almost every visitor. The Central American States of Guatemala, Honduras and Salvador also contains many objects of interest to the student of primitive culture, showing the continuance old Maya cus- toms. A great part of the Japanese exhibit is devoted to education in that country, and is designed to show not only the method of adopting new ideas, but the old customs are also set forth in quaint apparatus of older types. . Quite a number of very primi- tive devices are also among the newer ones, lighting them up with excellent effect. The Chinese department is devoted to showing the cotton in- dustry in that conservative country. It is excellent. Here upon a series of wall screens is painted the whole operation from the planting to the wearing out. Around the space you see first a man ginning cotton with a little wooden thing that looks like a rude clothes wringer. Just beyond another is whipping it with a bowstring, and from point to point you are led by a series of dum- mies until the whole process is before you.

MICROSCOPY:! . THE Uses oF CorLonion.—In modern histological technique collodion has come to serve a variety of important purposes. Duval? was the first to call attention to its advantages as an im- bedding mass. He found that it penetrated preparations easily and thoroughly ; that it could be quickly brought to the proper degree of hardness in alcohol of 36° (80 %); that objects thus imbedded could be preserved in this alcohol for an indefinite length of time; that the imbedding mass preserved its transparency, so that the preparation could be easily examined; that the sections did not require to be freed from the mass, since they could be colored and mounted in glycerine, and the mass remain unaffected by the process. As soon as Duvgl’s discovery became known, Merkel and Schiefferdecker’ began to experiment with collodion, and greatly improved and extended its use. It was found desirable first of all to be able to vary the concen- tration of the collodion, an end very conveniently reached by Merkel through the use of a solid preparation, called cel/oidin, which he dissolved in absolute alcohol and ether in equal parts. uval mounted sections of objects imbedded in collodion in glycerine, and was unsuccessful in his experiments with balsam. 95 per cent alcohol, and clarifying in oil origanum or oil of ber- gamot, the sections could be mounted in balsam (“ Microscopy,” Aug., 1884, p. 843). Some improvements of minor importance in the process of im- bedding have been made by Thoma, Blochmann and others. e importance of collodion in microtomy was much increased by the discovery that in combination with clove oil it could be 1 Edited by Dr. C.

Prof. Gage,’ who began to experiment with collodion as a fixa- tive prior to the publication of Schallibaum’s method, has given some valuable directions respecting its preparation and applica- tion. (3age- applies the collodion and clove oil separately, first coating a number of slides with collodion, which is poured on to one end of the slide and allowed to flow quickly over it and off into the bottle; and then, at the time of using, adding a wash of clove oil. In order to remove any cloudiness that may arise in the collodion film, a little clove oil is added to the balsam. _ The use of collodion to prevent the crumbling of brittle sec- tions originated with Norman N. Mason.? The same method was employed in Semper’s laboratory by Timm,’ Will“ Sarasin, Sharp and others ; and Mark has found it indispensable in sectioning the ova of Lepidosteus. Mason applied the collodion by means of a fine brush, taking up a small drop and placing it “in the center of the object so as to allow it to flow out on all sides to prevent the formation of air bubbles. After being allowed to harden a min- ute, the section may be cut and placed on the slide with the film of collodion underneath,” Mark and others who have used collodion for the same pur- pose, simply paint the cut surface of the object with a thin film a few seconds before making each section. Celloidin Injections—In the formation of injection masses collodion plays still another important role, for the discovery of which we are indebted to Schiefferdecker.6 It can be made to but not enough to form a serious drawback. It is prepared in different ways according to the color to be given to the injection. A. Asphalt Celloidin Injection —1. Pulverized asphalt placed in a well closed bottle of ether and allowed to remain twenty-four hours, during which the mixture must be several times shaken. : brown-colored ether is turned off, and small pieces of celloidin dissolved in it until the solution flows like a thick oil.’ 1 The Medical Student, p. 14, Seane, 1883. 25. 8Semper’s Arbeiten, VI, p. 110, 1883. 5 Semper’s Arbeiten, VI, 1883. “L & p 20i. : 1The pulverized alt can be used many times over for coloring the ether, as very little of it will dissolve in twenty-four hours. | 628 General Notes. [June, B. Vesuvian Celloidin Injection—1. Make a saturated solution of Vesuvian in absolute alcohol. 2. Dissolve in this pieces of celloidin until the desired consist- ency is reached. The brown injection thus obtained is less satis- factory than that formed from asphalt, as its color fades some- what. C. Opaque Celloidin Injections —1. Dissolve celloidin in abso- lute alcohol and ether in equal parts. 2. Add vermilion or Prussian blue to color. The coloring substance should be mixed with a small quantity of absolute alcohol and then reduced to great fineness by con- tinued trituration in a mortar. To the thick paste-like mass thus obtained the solution of celloidin is next added. The amount of coloring substance should be as little as possible, as the mass will otherwise be too brittle. If a fine injection is required the mass should be filtered through flannel moistened with ether. The syringe employed must be entirely free from fatty substances, as these render the injection mass brittle. If the piston does not fit the syringe tube sufficiently closely, it may be wound with a lit- tle gauze. The cannula should be filled with ether before it is in- serted and tied in place, and again filled just before it is joined to the syringe. In using a mass dissolved in alcohol ‘and ether it is well to the tissues. After injection the syringe and cannula should be cleansed with ether, ~ e injected organ is placed in hydrochloric acid, diluted more or less according to the danger of shrinkage. It is left in the acid, which is occasionally renewed, until the tissues are suffi- ciently corroded to be easily washed away by a slow and steady stream of water, conducted through rubber tubing connected with a water-pipe. The preparation may then be left in water for some days or weeks in order to free it from remaining fragments of tissue by gradual maceration. The preparation when finished, may be preserved either in glycerine or a mixture of glycerine, alcohol and water in equal parts. The asphalt-celloidin mass is the one most highly recommended by Schiefferdecker.— C. O. Whitman. _ Nors ON SEcTION CutTinc.—My only apology for the present communication is the hope that it may prove a saving of time to those who have encountered the difficulties of cutting eggs which are composed largely of yolk corpuscles liable to crumble in the ordinary paraffine method. The difficulty I have experi- ~ enced lies not alone in the impossiblity of making sections—even _ from eggs very thoroughly permeated by the paraffine—which NG. 1885.] Microscopy. 629 will not crumble during the removal to the prepared slide, but also in the fact that sections successfully transferred to the slide are liable to have portions of the yolk granules loosened an ign over other portions of the sections during the removal of paraffine. While by the ordinary methods of mounting (Geisbrecht, Schallibaum) those elements of the section which lie on its under side, and therefore come in immediate contact with the fixative, are ‘safely held in place, it may happen that man from the upper surface are loosened and washed away, because the fixative does not penetrate the whole thickness of the section. This obstacle may be entirely avoided by the proper use of col- We are indebted to Mason,! so far as I am aware, for the first suggestion of the use of collodion in this connection. But the method employed by Mason has serious objections. A drop of collodion on the surface of a paraffine-imbedded preparation soft- ens the object to such an extent that cutting is a very slow pro- cess, and thin sections are not easily attainable. The thickness of the collodion film, moreover, interferes more or less with accurate study of the mounted object, even if the sections are inverted when applied to the slide. The gradual drying of the surface of the film also causes the section to roll into a hollow cylinder with its collodion surface innermost, so that the inversion of the sec-. tion becomes difficult if not altogether impossible. The consist- ency of the collodion to be used is stated by Mason, but this is of little value since even a short exposure to the atmosphere often repeated will quickly change the condition of the collodion in the bottle. - All these impediments—but for which the method, I believe, would have come into more general use—may be largely if not aeaea obviated by using a very small amount of a rather thin collod The Eaterted which serves me is: the collodion must dry almost instantly (within two or three seconds after being applied) without leaving a trace of glossiness on the surface of the paraffine? In this collodion process T use at present the following method: The object imbedded in paraffine in the ordinary way is placed in a receiver of a Thoma’s microtome and the cut away to within 1™™ to 2™™ of the object on four sides, 1N.

[June, leaving a rectangular surface of paraffine, two edges of which are parallel to the edge of the knife. A slide prepared by being painted with æ ¿kin coat of Schalli- baum’s mixture of collodion and clove oil is placed at the left of the microtome. At the right of the latter, handy to the right hand, is a small bottle half full of the thin collodion, into which dips the tip of a camel’s hair brush; the quill of the brush is thrust through a hole in a thin flat cork which serves at once as a temporary cover to the bottle and a support to the brush, the latter being adjusted to any height of the collodion by simply shoving it up or down through the hole in the close-fitting cork. Near by is a small bot- tle of ether with which the collodion is thinned as soon as it be- gins to leave a shining surface on the paraffine. The operator should sit facing the light, so that he may judge accurately of the condition of the surface of the paraffine, which reflects the light. Everything being in readiness the brush is lifted and wiped on the mouth of the bottle to remove the most of the collodion, and then the paraffine and object are at once painted by quickly drawing the brush across the surface, care being used that it is evenly applied and that the collodion is not carried on to the vertical faces of the block. The temporary moistening vanishes like a clond from the surface of the paraffine, the brush is re- turned to the bottle at once; the knife is drawn and returned, leaving the section on the edge of the blade. The object in the block is then painted again, but before drawing the knife a second time the first section is removed with a scalpel and placed on the slide with its upper face in contact with the fixative. Then the knife is drawn again, and the other steps of the process repeated. Thus the collodion has time to thoroughly dry before the section is made, But if the precautions above given are observed, it will not be necessary to wait for the drying of the collodion and the sec- tion may therefore be cut at once, z. e., within five seconds after painting. It is thus possible to cut as fast as one can paint the surface, and with some practice it becomes possible to cut con- . . tinuous ribbons of sections which may be transferred at intervals. ‘Practically I find it most convenient to cut enough to form one row or half a row of sections at a time and transfer at once to the 1885. ] Scientific News. 631 the section being thrown under the knife blade, may, however, be obviated either by carefully trimming the vertical face in case it is accidentally painted (to allow for which the Aither margin of the paraffine may be left broader than the other three), or by drawing the knife s/ow/y, so that the first indication of a failure to cut through the vertical film may be recognized and the section held in place on the blade by a slight pressure with a soft brush, where- upon the knife will cut through the film and leave the section free. If by chance the paraffine block has been painted with too much collodion or with collodion which is too concentrated, thus leaving a shiny surface, the film should be at once broken by pressing it gently two or three times in quick succession with the end of a rather stiff, blunt, dry brush. This enables the col- lodion to dry quickly and thus prevents the softening of the paraffine. If the sections have a tendency to curl they may be flattened out on the slide by means of a brush, for a section thus impreg- nated with collodion may be handled during the first few seconds after contact with the Schallibaum mixture with much greater impunity than one not so treated. If the collodion has been too much thinned with ether, the fact will become apparent from the softening of the paraffine, and may be remedied by waiting for the evaporation of the ether, or by adding thicker collodion. This process can be in no way considered as a substitute for the ordinary method of cutting objects since it requires more time and closer attention to details, but for those cases where ` there is a liability to crumbling, or where sections of sufficient thinness cannot be procured free from folds, it will doubtless be found very serviceable-—Z.

EVOLUTION IN THE VEGETABLE KINGDOM. BY LESTER F. WARD, A.M. i ge law of biologic evolution (for it is no longer a mere “doc- trine ”) may be regarded as fairly established, no large and respectable body of scientific men being any longer found to oppose it when stated in its most general form, while difference of opinion and discussion have narrowed down to the more special aspects and minor details. In the animal kingdom, where organization is generally so high and structure so definite, great ` progress has been made in discovering the particular lines along which development has taken place and something like a true genealogy of the existing types has been worked out. The law of phylogeny is abundantly established by palzontology and sur- prisingly confirmed by embryological ontogeny. In the vegetable kingdom this last important class of evidence is almost wholly wanting, and paleontological evidence, owing to the lower structural rank of plants, is far less complete and - convincing than in the animal. It is proposed in this article briefly to inquire what vegetable palzontology has to present in favor of evolution in plants. The subject may be considered under three somewhat distinct points of view, the historical, the geological and the botanical. I. HISTORICAL VIEW. It is a common observation that botany is far behind zoology in supporting advanced biological theories. This is still more strikingly true of the study of extinct than of that of living forms, for not only were the ancients wholly unacquainted with any form of vegetable petrifaction, although familiar with fossil shells, VOL, XIX.—NO. VII. 42 638 Evolution in the Vegetable Kingdom. (July, madrepores and other animal remains, but when at last the era of science dawned toward the close of the eighteenth century Blu- menbach had for many years been sounding the key-note of pa- lezontological truth in the animal kingdom before Schlotheim took up the refrain in favor of plants. _ When we consider the present state of knowledge respecting the geological strata of the earth’s crust, we can scarcely realize that but two generations ago comparatively nothing was known on this subject. Geology was not yet born. The investigators of the last century were really not discussing the geologic age of fossil remains. With those who studied fossil plants the assump- tion was universal that they were plants that grew somewhere in the world only a few thousand years ago at most, plants such as either grew then in the countries where their remains were found or in other countries from which they had been brought by one agency or another, generally that of the Flood, or else, as some finally conceived, had been destroyed by these agencies, so as to have no exact living representatives. {n the year 1804 appeared Baron von Schlotheim’s “ Flora der Vorwelt,” as it is now universally quoted, although the author himself merely entitled it a “ description of remarkable plant im- pressions and petrifactions—a contribution to the flora of the former (or primeval) world.” To us this seems modest enough, but in view of the history of palzontology, the second part of this title amounted to a bold declaration, and accordingly we find him defending it in his introduction by these words: “The pet- rifactions which so early engaged the attention of investigators, and which, without doubt, afforded one of the first incentives to the founding of mineral collections and to the earnest study of _ mineralogy and geology, have, as is well known, since Walch - began to arrange them systematically, been for a long time, as well in as out of Germany, almost wholly neglected. They were content to regard them as incontestable proofs of the Deluge, which closed all further investigation until they were at last com- pelled to explain their occurrence through other great natural operations which had probably been going on earlier and more universally: than the flood described in the Bible, and influencing the formation of the upper strata of the earth’s crust; and more ~ recent observations and investigations have even led us to the i y probable supposition that they may be the remains of an 1885.] Evolution in the Vegetable Kingdom. 639 earlter so-called pre-Adamitic See the originals of which are now no longer to be found. * * In the continued investiga- tion of this subject this opinion, with certain restrictions, has in fact gained a high degree of probability with the author of the present work, so that he ventures to announce his treatise as a contribution to the flora of the ancient world (Vorwelt).” Since its introduction by Schlotheim this expression; “ Flora der Vor- welt,” has been applied to nearly all the German works on fossil plants, and “ Beiträge zur Flora der Vorwelt” still continue to appear. This work was followed, though sixteen years later, by his “ Petrefactenkunde,” and also by Count Sternberg’s important “attempt at a geognostico-botanical presentation of the flora of the ancient world.” These men were the pioneers of vegetable paleontology. It was reserved for Adolphe Brongniart to be- come its true founder. Brongniart’s paper on the classification and distribution of fossil plants, which was published in the memoirs of the Paris Museum of Natural History in 1822, showed that he had already been some time at work, and after six years of nearly complete silence he at length came forward, in 1828, with his epoch-making works on the history of fossil plants; the “ Pro- drome” and the “ Histoire des végétaux fossiles ”—which, taken together as was the design, form the solid basis upon which the science has been erected. Brongniart’s fundamental conception was, that fossil plants were none the less plants, and that so fast as they really became known they should be placed in their proper position in the vegetable series and made to form an integral part of the science of botany. In his classification he therefore had due respect for the natural system as then understood, but he nevertheless felt that geognos- tic considerations must be taken into the account, and he saw © with almost prophetic vision that in passing up through the geologic series higher and higher forms of vegetable life pre- sented themselves. Although unable to understand the complete continuity in the series, as modern evolution postulates, and although affected by the Cuvierian idea of successive destruc- tions and re-creations, still he insisted that each suecessive crea- tion was superior to the one it had replaced, and that there had thus been, as it were, a steady progress from the lowest to the highest forms of vegetation. He divided the geologic series into 640 Evolution in the Vegetable Kingdom. (July, four great periods, the first extending through the Carboniferous and corresponding to the modern Palzozoic, the second embrac- ing the Grés bigarré, or Buntersandstein, only, the third seeming to include the rest of the Trias, the Jurassic, and the Cretaceous, and the fourth completing the series. The table which he gives on page 219 of the “ Prodrome” is designed to show the devel- opment of the higher types of vegetation in successively higher strata, and in discussing it he remarks that “in the first period there exist hardly anything but cryptogams, plants having a more simple structure than that of the following classes. In the sec- ond period the number of the two following classes becomes pro- portionately greater. During the third period it is the gymno- sperms which specially predominate. This class of plants may be considered intermediate between the cryptogams and the true phanerogams {dicotyledons} which preponderate during the fourth period.” The words italicized in the liberal translation here made are scarcely less than a prophecy, and one whose fulfillment is only now being tardily granted by systematic botanists. As the result of his prolonged studies, Brongniart finally arrived at the following remarkable classification of plants, as drawn up on page 11 of the “ Prodrome,” and repeated on page 20 of the “ Histoire :” 1. Agams. 1. Cellular ae io tor ur. Vascular cryptogam: iv, Gymnospermous RAE v. Monocotyledonous angiospermous phanerogams. VI. Dicotyledonous angiospermous phanerogams. In the present state of botanical science Brongniart’s “ agams” would probably all be relegated to his second group, or cellular cryptogams, but in other respects this classification is preémi- nently sound, and seems likely to be vindicated by the future _ progress of science, It will thus be seen that Brongniart founded the science of vegetable palzeontology firmly upon the law of progressive devel- opment, and there can be little doubt that if his influence could have been felt by botanists as it was by vegetable paleontologists in general, botany might have advanced pari passu with zodlogy, : ae : was far in advance of his time, and his views were z — d to meet wn violent opposition. His method was, with 1885.] Evolution in the Vegetable Kingdom, — 641 few exceptions, adopted by subsequent palzo-botanists but never by botanists proper. The most powerful antagonism to this effort of Brongniart to confirm Lamarckian principles from the phytologic side thirty-one years before the appearance of Darwin’s “Origin of Species” was offered by the eminent English botanist, Dr. John Lindley, who found a fitting occasion to meet the great French palzon- tologist on his own ground while engaged with William Hutton in the preparation of their “Fosssil Flora of Great Britain,” 1831—37. Of this truly great work we are here concerned only with certain discussions which were directed against the then infant doctrine of biologic evolution in the vegetable kingdom, and which were not only marked with great acrimony, but were allowed to influence and to warp the classification adopted by the authors into forms which even to botanists now appear ridicu- lous. The introductory remarks in the first volume, as well as much of the general discussion throughout the work, are charac- terized by a most astonishing and apparently willful ignorance of the true principles of palzo-phytology as they were set forth by Brongniart, Sternberg and even Schlotheim, and which are now universally accepted. One of Dr. Lindley’s remarkable aberrations was the perti- nacity with which he contended for the existence of cactaceous and euphorbiaceous plants in the coal measures. It is true that Parkinson had seen a fancied resemblance between cer- tain stems and those of large cacti, and similar guesses had been made by Volkmann, Walch and other authors of the eighteenth century, when it was supposed that the counterpart of every fossil plant must be found in the living flora, but all these imaginings had been long since laid aside only to be revived by the leading botanist of Europe. The theory of a former tropical climate in England and on the continent of Europe was assailed, the existence of tree-ferns in the Carboniferous was denied, the relation of the Calamite to the Equisetaceæ questioned, and many other tolerably well estab- lished generalizations were remanded to the domain of dou and discussion. The true secret of this sweeping skepticism is, however, not far to seek. It is found in the more general denial, which was finally made, of the conclusion to which the acceptance of these 642 Evolution in the Vegetable Kingdom. [July, rejected theories would naturally lead and had actually led M. Brongniart and others. The authors say: “Of a still more ques- tionable character is the theory of progressive development, as applied to the state of vegetation in successive ages. In the vegetable kingdom it cannot be conceded that any satisfactory evidence has yet been produced upon the subject; on the con- trary, the few data that exist appear to prove exactly the con- trary.” All the denials and assertions made in the work opposed to Brongniart’s teachings are made to support this view. The existence of Cactaceze, Euphorbiacez and other dicotyledons in the Carboniferous would negative development; the admission of ` a former tropical climate was a strong argument for the nebular hypothesis as well as for geologic progress; tree-ferns would argue such a former tropical climate; if Calamites could be shown to bea Juncus, a higher type would be found in Paleozoic strata than Brongniart believed to occur. Still another good point was thought to be gained by proving what is now admitted, viz., that coniferous plants occur in the coal. All botanists then held, as many still hold, that the gymnosperms were a subclass of the dicotyledons, coérdinate with the dicotyledonous angiosperms But, curiously enough, Brongniart had forestalled this argument by making the gymnosperms of lower type, intermediate between the cryptogams and the angiospermous phanerogams. By a special insight, characteristic of true scientific genius, he had used their lower geological position as a proof of their lower organization, z. ¢., had postulated evolution as an aid to organic research—a method which is now becoming quite common, al- though unsafe except in the hands of a master, Dr. Lindley laid much stress upon the fact “that no trace of any glumaceous plant has been met with even in the latest Ter- tiary rocks,” thus freely employing the fallacy which he else- where warns others to avoid, that because a class of plants has not been found, therefore it did not exist at a given geologic epoch. But to cut off the possibility of a reply to the position he takes he finally declares that “ supposing that sigillarias and stigmarias could really be shown to be cryptogamic plants, and that it could be absolutely demonstrated that neither Conifer _ for any other dicotyledonous plants existed in the first geological __ age of land plants, still the theory of progressive development 5 : would be untenable, because it would be necessary to show that 1885. ] Evolution in the Vegetable Kingdom. 643 monocotyledons are inferior in dignity, or, to use a more intel- ligible expression, are less perfectly formed than dicotyledons. So far is this from being the case that if exact equality of the two classes were not admitted, it would be a question whether mono- cotyledons are not the more highly organized of the two; whether palms are not of greater dignity than oaks, and Cerealia than nettles.” Teleologic and anthropocentric reasoning like this pervades all the discussions in this work and vitiates the scientific deductions. The elaborate experiment that Dr. Lindley made and described in the first dozen pages of the third volume, was obviously animated by the same spirit of uncompromising hos- tility tothe development hypothesis. By showing that the higher types of plants when long immersed in water are earlier decom- posed than ferns, conifers and palms, he thought he had demon- strated that the reason why we find no dicotyledons in the Car- boniferous is simply because they had not resisted, and from their nature could not resist the destructive agencies to be overcome in the process of petrifaction. One could wish that he might behold the four thousand species of fossil dicotyledons now known, and realize how vain had been his experiment as well as all his theorizing ! It is such resistance as this, coupled with the power of the Jus- siæan method, that has retarded the progress of correct ideas respecting the development of plant life. Systems of classifica- tion have been chiefly modeled after those of the early founders.. The text books of botany still generally invert the order and begin with the phanogams, although this is doubtless merely intended to facilitate study, and does not at all imply that our leading botanists believe this to have been the order in which plants have developed. This inversion of the order, however, shows how completely the notion of development is ignored in modern botany, and the system throughout rests upon the evi- dence furnished by the organs of the plants as they are under- stood. Nevertheless, it is proper to say that at the present time quite a large body of the most thorough students of vegetal em- bryology and histology, chiefly in Germany, have rejected much of the modern system of botanical classification, and especially that which concerns the position of the gymnosperms. They prove in the most satisfactory manner that these plants constitute a lower type than any of the remaining phanerogams, and they F 644 On the Vertical Range of Certain Fossil Species [July, also find that in their reproductive organs they form a more or less natural transition from the cryptogams to the phænogams, between which they place them. This result is most gratifying to the palæo-botanist, for nearly all works on fossil plants give the gymnosperms this position at the base of the phænogamic series, so sagaciously assigned to them by Brongniart. They have been compelled to do this in the face of the prevailing botan- ical systems, because this is the position which they are found to occupy in the ascending strata of the earth’s crust. It is aston- ishing that botanists could have remained so indifferent to such a weighty fact, and it is certainly most instructive to find the geo- logical record, so long unheeded, confirmed at last by the facts revealed in living plants. There is no evidence that those who have thus confirmed it were in the least influenced by it, since Sachs and Caruel are as silent respecting paleontology as De Candolle or Bentham. The founders and perfecters of the prevailing system of botan- ical Classification have not been influenced to any marked degree by the idea of development in vegetable life. Few of the earlier ones had ever heard of development, except at least as a vision- ary theory. This system had become established long before the doctrine of the fixity of species had received a shock, for although Lamarck, himself a botanist, had sown the seed of its ultimate overthrow, still it required half a century for this seed to germi- nate, and it was during this half century that the Jussizan system was supplanting the Linnzan and gaining a firm foothold. Shaking off, for the time being, all fixed allegiance to any sys- tem, let us glance fora moment at the lesson which vegetable palzontology now teaches upon the subject of development. (To be continued.) 10: ON THE VERTICAL RANGE OF CERTAIN FOSSIL SPECIES IN PENNSYLVANIA AND NEW YORK. BY PROFESSOR E. W. CLAYPOLE. 1 Second Geological Survey of Pennsylvania has recently published a report on Montour, Columbia and several other _ counties, written by Professor I. C White, of the University of mSS Virginia. While engaged in the work Professor White the writer to determine for him the fossils which he 1885.] in Pennsylvania and New York. 645 collected, This was done, and the results were embodied in the volume in question, G, of the Pennsylvania reports. In the preface to the volume Professor James Hall, of Albany, has, through the State geologist, honored the paleontological portion of the work with certain criticisms which call for a few remarks. The science of paleontology advances so rapidly that statements which were perfectly correct at one time often cease to be so, and from this ground, if from no other, the criticisins contained in the preface of Professor White’s report require some notice. L It will not be necessary at any length to discuss Professor Hall’s first remark concerning the dividing plane between the Chemung and the Catskill. In the present state of our know- ledge this must be largely a matter of opinion. One observation will suffice. Whatever may ‘be the fact in Montour and Colum- bia counties, there is no doubt that in Perry county, with which the writer is better acquainted, spirifers, unbroken and with both valves in contact, are found about 1000 feet above red sandstone beds holding the scales of Holoptychius or Bothriolepis or both. I, In regard to the spirifers of the Chemung, certain statements are made which are not in harmony with facts which the writer has observed in Middle Pennsylvania. For instance, on page xx we read: “How is it possible to credit such a topsy-turvy appearance of the three species of Spirifera which, outside of mh aise, have been found (1) never in any but ‘Chemung roc ocks; (2) co fined each to its own horizon; and (3) always ina fixed sage from above downward, thus : Spir ifera disjuncta horizon (S. dj.). Spirifera mesocostalis horizon (S. mc.). Spirifera mesostrialis horizon (S. ms.).” On page xxi we read further: “ Spirifera cin aia and Spirifera mesostrialis form an impossi- ble ? conjunction This assertion must be, to say the least, somewhat hazardous even with the interrogative point. Again, on the same page: “Professor Hall has never seen any two of the three species 646 On the Vertical Range of Certain Fossil Species (July, coexisting in the same stratum or at the same horizon or outside the limits of the typical Chemung. He would not be surprised if S. mesocostalis were found to ascend high enough above its proper horizon to mingle with S. disjuncta. But he cannot com- sae how S, disjuncta and S. mesostrialis should be found to- gether. In regard to this point the experience of the writer in Penn- sylvania has led him to very different conclusions. So far from being strictly limited to single horizons, these three species appear to range with great latitude over each other's territory. This is especially true of the two lower fossils, S. mesocostalis and S. mesostrialis, It is no doubt true that each species is specially abundant in certain beds or zones, but while in a measure charac- terizing these, it spreads both above and below them, and mixes with one or both of the others. These statements are made concerning Middle Pennsylvania and have no reference to any other district. The writer’s expe- rience among the rocks and fossils of New York is not sufficient to enable him to speak with any authority concerning them, and to these it may be supposed Professor Hall is chiefly referring in the passage quoted above. Since the publication, however, of the report of Professor White, and called forth by its preface, a letter has appeared from the pen-of Professor H. S. Williams, of Cornell- University, in which, referring to these remarks of Professor Hall, he says: “While the statement cited may express the general rule as to the occurrence of the species in New York State, there are specimens in Cornell University museum which do not bear out the statement. “In the first place the two species, S. mesostrialis and S. meso- costalis, are found associated in the same stratum at Ithaca, N. Y., both in the mesostrialis zone and in the mesocostalis zone. Sev- eral instances can be shown where they occur on the same slab. “ From a higher horizon in New York State, and from several localities, either of these species may be found associated with S. disjuncta, and I have obtained each of the three ney from the “representatives of S: notte and S. senses ` the latte tter pre- -serving ‘ the fine radiate striæ with delicate concentric crosslines’ — without ut a depression’ which are describéd as distinctive charac- A T pe (Pal. N. Y., Vol. iv, p. 243). 1885.] in Pennsylvania and New York. 647 “The other specimen, only a couple of inches distant, has the characteristic plications on the medial fold, and with the surface equally well preserved, shows not the least nn = radiate or Sohne strie, unmistakably indicating S. disjun “From the same locality, though not on this individual slab, are specimens of both varieties of the so-called S. mesocostalis— the large coarse form with angular plications and reduplicated fold, and the more finely plicated form with prolonged hinge line which is more characteristic of a lower horizon.’ From these statements of Professor Williams we find that the three following inferences are now known to be true for Mew York State: 1. That S. mesocostalis occurs associated with S. mesostrialis. 2. That S. mesocostalts occurs associated with S. disjuncta. 3. That S. mesostrialis occurs associated with S. disjuncta. These are all the possible combinations of three things taken two together. Consequently these three species are mingled in New York State in all possible ways in which two of them can be combined. In order to strengthen, if possible, by cumulative evidence the argument founded on these clear and definite statements, the- writer applied to Professor R. P. Whitfield, of New York, asking if the collection of the New York Museum of Science, of which ` he is curator, could supply any facts that would support the views on the range of these fossils which are here maintained. The greater part of that collection was made and the specimens named by Professor Hall, so that no doubt regarding the identi- fication of the species can be entertained. Professor Whitfield has stated in reply: 1. “Ona small block of sandstone containing the specimen of S: p ipaairsy figured in the Palæontology of New York (Vol. Iv, Pl. xL, Fig. 6), there is an imprint of a part of a very charac- me iA of S. disjuncta. “ Another specimen measuring four inches by three, from Schoharie county, N. Y., and bearing Professor Hall’s ticket (No. 302), contains one of the specimens of S. mesostrialis, figured in the same plate (Pl. xx), and also casts or imprints of three indi- viduals of S. mesocostalts, 3. “ Another small slab marked, in Professor Hall’s writing, ‘ Tioga county, N. Y.,’ contains two dorsal valves of S. disjuncta and two ventrals of S. mesocostatis. a antes small block, bearing Professor Hall’s ticket, shows dorsal valves of S. mesocostalis with specimens of the long mu- cronate hinged form of S. disjuncta. 648 On the Vertical Range of Certain Fossil Species _ [July, s. “One from Vandermark’s creek with large examples of S. disjuncta contains a ventral valve of S. mesocostalis. 6. “ Another bearing Professor Hall’s ticket (279), from Cayuta creek, N. Y., has S. disjuncta with S. mesocostalis.” Professor Whitfield also adds : “ On one small specimen weighi ng ten or twelve ounces and bearing the label ‘ Cayuta creek,’ with characteristic specimens of S. mesocostalis and S. disjuncta, there is an imperfect imprint of the medio-dorsal part of a ventral valve presenting the features of S. mesostrialis as it occurs at some western localities [of N. Y.], but its outline is too imperfect to admit of positive identifi- cation. The testimony obtained from the collection in New York, therefore, agrees in every point with that given in Professor Wil- liam’s letter, and suggests in addition the possible association of all the three species at Cayuta creek. Yet one fact more may be given. Professor H. W. Geiger, of the U. S. Geological Survey, has informed the writer that he pos- sesses a slab from the Chemung of Virginia on which S, meso- strialis and S. disjuncta are lying side by side. In the face of these facts it is quite impossible any longer to maintain the sharp delimitation of the horizon of these three spe- cies above and below. It is evident that though characterizing, probably in some places by their abundance, certain zones, they are not by any means limited to these zones, but invade each other’s territory to an undefined extent. This result is more in harmony than its opposite with our pres- ent views of the progress of life on the globe. We have no rea- _ son to believe that species came suddenly into ascendancy and then as suddenly went out, especially at times unmarked by any catastrophe, as was the case in the Chemung era in Middle Penn- sylvania and New York. On the contrary, the general belief in evolution involves the special belief that every species has, in ordinary circumstances and barring accident, had its time of rising, culmination and decline, during which its life has overlapped the life of other kindred and perhaps derived species. Nothing is less likely, a priori, than that three species of spirifer should lie like three drawers in a geological cabinet one above another. Noth- _ ing is more likely than that each should occur in gradually in- -~ ¢reasing numbers until it reached its maximum, and then in grad- ad diminishing numbers until it died away. Each may then 1885.] in Pennsylvania and New York. 649 - distinguish certain horizons, as Professor Hall describes them, but without sharp and decisive limitation to these horizons. It is farther possible, and not improbable, that these zones of maximum abundance hold the same relative positions to one an- other in New York and in Pennsylvania. This, however, must be decided by closer study. Nothing that the writer has seen or published is antagonistic to such belief. But even if the zones of maximum abundance should not hold the same relative positions to one another in different parts of the country, we are not driven to the alternative of asserting a “subversion of specific types in vertical range ” (p. xxvi). Given the three species, or indeed any two of them, living side by side through the greater part of the Chemung era, and we need only admit that local conditions favored here the one and there the other, and the whole difficulty disap- pears. It is purely imaginary. It is scarcely probable that iden- tical conditions of life existed contemporaneously over so great an area, it need not consequently shake our belief in palzontol- ogy if the result should show that in Pennsylvania and Virginia, or in States still more distant, the zones of maximum abundance hold an order different from that which Professor Hall has laid down for New York. Another fact may be mentioned in this connection which, though not directly connected with the argument, yet serves to show that the lines of delimitation bounding the range of fossil spe- cies cannot be laid down as definitely as has been done by some palzontologists. - S. /evis is one of the characteristic fossils of the Portage group in New York State occurring neither above nor below, so far as the writer is aware. Yet in Middle Pennsylvania it has not been found in the strata occupying the position of the . Portage of New York, and holding other Portage fossils. But it does occur higher up, in the Chemung proper, and in company with S. mesocostalis S. levis, it may be added, is a well charac- terized species in New York, and is therefore readily recognized. HL Passing on to another topic, we find on page xxii: =“ Orthis tulliensis has certainly never been seen before in the Chemung two hundred feet above the Genessee (ż. e., three hun-, dred feet above the Tully limestone), nor in the company of S. mesocostalts,” 1 This is possibly S. mesostrialis. The specimen is only a fragment. 650 On the Vertical Range of Certain Fossil Species [July, This statement may be strictly true, but it may be urged, on the other side, that there is no distinct character by which O. tulliensis can be separated from O. impressa. No doubt two forms can be picked out as types of the so-called species, but their vari- ation is considerable and they run into one another, It would be exceedingly difficult, perhaps quite impossible, to separate accu- rately a mixture of the two species if the horizons of the speci- mens were unknown. We seem here to have an example of a vicious reasoning of which palzontology affords not a few simi- lar instances. The Orthis from the Tully limestone is called O. tulliensis ; that from the overlying Chemung is called O. impressa. But barring this difference it would be hard to draw a line be- tween them. The practice of giving different names to fossils simply because they come from ‘different horizons has been car- ried too far. It has created artificial barriers in the way of tracing the evolution of species and the connection of strata. Neither geological nor geographical separation is sufficient reason for distinguishing by name fossils between which no clear structural difference can be pointed out. The cases are few, especially among the Testacea, that justify resort to the argument used by the late Professor Meek, “that if the whole structure of the ani- mal had been preserved doubtless some distinctions would be found which do not exist in the fossil.” Referring to the extract given above from the preface of Gy, Professor Williams says in the letter already quoted: “In regard to Orthis tulliensis it may be said that the common Orthis occurring at the base of the Ithaca fauna within a few hundred feet above the Genessee shale (less than 500) resembles at its first appearance Orthis tulliensis in form and general charac- ter, though for distinctness it may be appropriate to call it a vari- ety of Orthis impressa, since a little higher and in the same fauna the typical Orthis impressa appears in abundance. “Still there are specimens in the collection, from the lowest zone, which it would be difficult for any one to distinguish by microscopic or macroscopic characters from O. tulliensis.” There is therefore in New York an Orthis which cannot be dis- tinguished from O. tudliensis, occurring not at 200 feet only, but at a yet greater height (less than 500 feet) above the Genessee shale. | in regard to the association of this fossil with S. mesocostalis, 2 Professor Williams adds ~ “T have no single slab containing this form with S. mesocostalis, 1885. ] in Pennsylvania and New York. 651 but the aner is found both above and below the stratum contain- ing the Ort IV. Reverting to the preface of G, we read on page xxii this remark, apparently by the State geologist : “ Halysites catenulatus [the common chain- coral] i is found aiite out of its natural place; at one locality only it is true, but such abundance as to make upa large proportion of the Genty feet pi Ees through which it is found.” . Logan recognizes it as low as the Trenton lime- stone, A I have seen a form or variety of the same in the Hud- son River group of Green bay,' but no one has ever before found it above the Niagara Professor Lesley adds very justly : “Whatever may be the difficulty of distinguishing S. disjuncta from S. mesostrialis, it is quite impossible for any one to mistake Halysites catenulatus, the characteristic form of the Niagara ax stone all over the United States and Canada, and also of the cor- responding Wenlock of Europe. In these passages there are obvious traces of the vicious rea- soning already condemned. The “natural” place of a fossil is surely that in which it is found. Its “ canonical” place may be very different. Now of the occurrence of Halysites catenulatus in the Lower Helderberg limestone at the place mentioned by Pro- fessor White, there cannot be the slightest doubt. The obvious character of the fossil, such that every tyro in paleontology is acquainted with it, precludes all chance of mistake in its identifi- cation. The position of the limestome bed in which it was found is equally decisive against stratigraphical error. It overlies several hundred feet of red shale and sandstone, which are the equiva- lent of the Onondaga shales of New York—the Salina shale or Salt group, as they are often called. The correlation of these has been satisfactorily determined in Middle Pennsylvania, and the evidence, both stratigraphical and paleontological, may be seen in the writer's report on Perry county (F,). It is proper to add here that the above statement concerning the place of the bed is made from personal knowledge, the ground having been visited for the purpose in company with Professor White. 1 Some inconsistency exists between this statement and that on p. xxv. “ Professor Hall has given himself infinite trouble to obtain the data on which rests the proof that Æ. catenulatus never occurs except in Niagara and Clinton rocks.” 2 Letter from Professor Hall. : 652 On the Vertical Range of Certain Fossil Species [July, Immediately above the limestone bed in question comes the Oriskany sandstone, so that the evidence for position is rendered doubly sure, and it would be idle, in the face of all the facts, to entertain any remaining doubt or suspicion regarding the horizon or the species of the fossil. It is Halysites catenulatus, and it is found in the Lower Helderberg limestone. Halysites catenulatus ranges in England from the Llandeilo up to the Wenlock, and in America from the Trenton to the Niagara, by consent of all geologists. At this horizon its disappearance has been assumed. But the determination here maintained car- ries it up through about 1200 feet of strata, and extends its spe- cific life through a correlative lapse of time. In the consideration of these facts it may be remarked that the very ease and certainty with which this fossil can be recognized appear to the writer a possible source of error. Being abundant at numerous places in the Niagara limestone, it forms a convenient fossil reference, and its range has been, by tacit consent and per- haps with the aid of influential names, assumed to be limited upward by the summit of the Niagara. It has thence become the practice to refer ail strata containing it to the Niagara group, and the two have become closely associated. Yet the foundation for so strict a delimitation is as unsatisfactory as in the cases pre- viously examined. It is in fact another instance of vicious rea- soning. Halysites catenulatus occurs very frequently in Niagara rocks, therefore all rocks yielding Halysites catenulatus are of Niagara age. : If this fallacy be avoided and the. upward range of Halysites be admitted, its occurrence in the place and on the horizon men- tioned by Professor White (in G,) instead of being “ a serious matter for Pennsylvanian geology” (p. xxiii), may be a matter of importance to the geology of some States outside of Pennsylva- Nia, and may even cause the removal to a higher level of some strata which have been hitherto placed in the Niagara group by the hasty deduction above condemned. For example, it is just possible, to say no more, that the occur- rence of this fossil in the cement beds, as at Kingston, N. Y., may be hereby explained. If these cement beds are the same as . those usually included under that name, they should lie in the : Lower Helderberg series and not in the Niagara, as often stated. Moreover a reference to Professor Hall’s geological map of New 1885.] in Pennsylvania and New York, 653 York State (Geol. N. Y., Vol. rv, 1843), and also to that of the Geological Survey of Canada, 1863, will show that no outcrop of the Niagara is represented within a hundred miles of Kingston, the color representing that group ceasing near Utica, while the Lower Helderberg continues and underlies the town. It is hard to resist the conclusion that we have here an instance of correct stratigraphy overruled by incorrect paleontology, and that so far from its occurring only in the Niagara this is an example in Vew York State itself of the occurrence of Halysites in the Lower Helderberg limestone.’ V. From the facts and arguments here set forth the general con- clusion must follow that all attempts to confine the range of species within certain arbitrary lines are attempts that are not likely to succeed. The geological record as written in the rocks is a record of life. Evolution teaches us that life advanced by slow stages from species to species ; that as one died out another took its place. Evolution knows nothing of breaks or of hard and fast planes of limitation in the range of species. All suc planes are indications of imperfection in the geological record, perhaps evidence of catastrophes on a small scale, but they are no proof of widespread, disaster and destruction. And in propor- tion to the advance of our knowledge we must expect, on the principles of evolution, to see these breaks one by one disappear, and these lines be one after another effaced until the record of the rocks is in harmony with the record of life which it represents. That this harmony will ever be perfect is unlikely, for the rocks will never give up all their dead, but that it will one day be much more nearly complete than now is axiomatic, in the face of the continual discovery of missing chapters in the history supplying missing links in the chain of life. The artificial systems of palaontology which have been con- structed by the faithful, earnest and devoted labors of the students of the science are but temporary. They are invaluable aids to the progress of the work, but they are only the means and not 1 On p. xxiii (G,) an error appears which causes some confusion, “S. ma is the earliest spirifer which shows ribs in the medial series (sinus ?), and it recurs nearly unchanged in the Subcarboniferous Chester limestone of the West.” & macropleura, as may be seen by looking at Professor Hall’s figures (Pal.

(July, the end. Progress will be hindered if these systems are allowed to cramp and fetter us. If preconceived notions of what should be are suffered to blind our eyes to what really zs, our palzon- tology would itself become a fossil, as dead as the trilobites of palzozoic days. Our subdivision of the geological column into Hamilton, Chemung, Catskill, &c., or even into Cambrian, Silu- rian and Devonian, &c., is simply a device to assist memory and classification, not to represent actual and separate creations. And with every new discovery we must expect to see the lines and planes that separate these imaginary groups and systems become less and less clear until they are fused into a whole whose parts shade into one another like the colors of the rainbow. Nature is larger than our systems, and our knowledge of fossil nature must some day outgrow our artificial “canons of paleontology.” But in all such cases nature cannot be warped to our “ canons,” our “canons” on the contrary must bend to the facts of nature. The writer cannot conclude without, superfluous as it may seem, adding a word to express his sense of the value of the labors of Professor James Hall in American paleontology. He has laid broad and deep foundations for future workers. How numerous or industrious soever they may be, they must always acknowledge that they are building over his beginnings. That some errors should creep into work so great and varied is to be expected. But compared with the grand whole, they are insig- nificant, In pointing out and correcting a few of these errors in the foregoing pages, nothing is farther from the writer’s wish an to seem to depreciate Professor Hall’s labors. The facts and misstatements here criticised are mainly details—mere spots on the face of the sun—but for that reason the more worthy of attention and scrutiny. +O: ANCIENT ROCK INSCRIPTIONS ON THE LAKE OF THE WOODS. BY A. C. LAWSON, M.A. WV HILE prosecuting a geological survey of the Lake of the Woods last summer, I observed upon the rocks, at two _ places not far distant from each other on the shores of the lake, _ ancient inscriptions which may be of some interest to those who : are F engaged | in gathering up and weaving together the scattered 1885.] Ancient Rock Inscriptions on the Lake of the Woods. 655 threads of evidence, which in the web display the checkered life- history of the aboriginal peoples of the American continent. I am induced to publish this note on the subject at present, rather than wait for further opportunities of collecting additional .mate- rial, because of the striking resemblance which some of the char- acters of these inscriptions bear to those of certain Brazilian rock inscriptions figured by Mr. John C. Branner in his interesting paper in the December number of the AMERICAN NATURALIST. The Lake of the Woods is divided about its middle into two parts, a northern and a’southern, by a large peninsula extending from the neck of land at Turtle Portage on the east side of the lake to within a very few miles of the west shore. On the north side of this peninsula, z. e., on the south shore of the northern half of the lake, about mid-way between the east and west shores, occurs one of the two sets of hieroglyphic markings to which I refer. The more typical examples of these are figured in Plate xIx. Lying off shore at a distance of a quarter to half a mile, and mak- ing with it a long sheltered channel, is a chain of islands trending east-and-west. On the south side of one of these islands, less than a mile to the west of the first locality, is to be seen the other set of inscriptions. The first set. occurs on the top of a low, glaciated, projecting point of rock which presents the characters of an ordi- nary roche moutonnée, The rock is a very soft, foliated, green, chloritic schist into which the characters are more or less deeply carved, The top of the rounded point is only a few feet above the high water mark of the lake, whose waters rise and fall in different seasons through a range of ten feet. The antiquity of the inscriptions is at once forced upon the observer upon a care- ful comparison of their weathering with that of the glacial grooves and striz, which are very distinctly seen upon the same rock surface. Both the ice grooves and carved inscriptions are, so far as the eye can judge, identical in extent of weathering, though there was doubtless a considerable lapse of time between the disappearance of the glaciers and the date of the carving. The ice grooves are not merely local scratches but part of the regular striation which characterizes the whole region. Both the striz and inscriptions present a marked contrast to some recent letters which passing traders or travelers, attracted by the novelty of the inscriptions, have cut into the rock, much in the same cei as that in which my Christianized Indian canoe-man pro- 656 Ancient Rock Inscriptions on the Lake of the Woods. [July, ceeded to carve his initials in the rock with my hammer the moment we landed. The weathered and rough character of the carving afforded no clue as to the tool used. In size the charac- ters varied from about three to twelve inches. There was no in- dication of ochre having been rubbed into the carving. The characters figured in Plate x1x were scattered over the rock sur- face in all directions and in greater numbers than are represented; and although the typical ones are gathered together on one sheet, that arrangement by no means shows their relative positions. The chief advantage to be derived by archzologists from an acquaint- ance with such inscriptions is the tracing out the similarity or identity of the individual characters with those of inscriptions found in other parts of the continent. There is little hope of any coherent meaning or narrative ever being derived from such iso- lated groups of characters. The similarity of some of the characters now figured to those described by Mr. Branner from the boulders of Alagéas is a striking and suggestive one. For example, No. 2, Plate x1x, is identical with the left-hand figure of Mr. Branner’s %, even as to the number of whorls and their direction. No. 25 is almost identical with æ and 4 of Mr. Branner’s plate. The horse-shoe or part-circle shape is distinctly common to both, as may be seen by comparing X and d of the Brazilian inscriptions with 17, 18, 21, 23, 24 and perhaps 29 of those from the Lake of the Woods. Nos. 7, 8, 15, 20 may be compared with Mr. Branner’s asterisk as simpler forms on the same principle. The circle is also com- mon to both sets. Nos. 1, 4, and 14 are similar in character to the 3d form from the top of Mr. Banner’s X. No. 10 has nearly the same shape as the 3d on the top row of the same group. No. 12 is not unlike Mr. Branner’s c and No. 19 is on the same principle as the chain_of small circles of his J. But there is no need of straining the comparison. The coincidence appears to be too strong to be purely accidental, although considering the remoteness of the two regions in question, much more abundant material for comparison would be required before inferences, even of the most general sort, could be drawn. = The island on which were found the other inscriptions to which nie ok have alluded, is one of the many steep rocky islands known _ among the Indians as Ka-ka-ki-wa-bic win-nis, or Crow-rock island. The rock is a hard greenstone, not easily cut, and the Indian Inscription: 1885.] Ancient Rock Inscriptions on the Lake of the Woods. 657 inscriptions (Fig. 1) are not, cut into the rock but are painted -with ochre, which is much faded in places.

Two of the forms, viz., 1 and 4, have a sufficiently strong resemblance to 16 and 9 respectively of Plate x1x, although one is in ochre and the other carved into the . rock, to lead to the belief that the two inscriptions are closely related in authorship. The Indians of the present day have no traditions about these inscriptions beyond the supposition that they must have been made by the “ old’ people” long ago. n 4 658 Kitchen Garden Esculents of American Origin.

It seems useless, therefore, to add the testimony of trav- elers of the sixteenth century, and which are not quoted by De Candolle? and by Gray and Trumbull,‘ for to those who would deny the accuracy of the vernacular names used, such transcripts would not be convincing. A most valuable argument, however, is the absence of certain identification of this class of plants with the names used by authors preceding the discovery of America,’ 1Travels, Hak.

Jour. of Si., May, 1883. . 5 The Cucurbita of the ancients was either Cücürbita, or Lagenaria, or Benincasa of modern botanies, a proposition to which all investigators will agree. The authors which I have at hand are Columella, Pliny and Palladius, covering the first and third century of the Christian era, From their writings we can infer two propositions, First, it could be a Lagenaria; second, it could not be Cucurbita maxima. Columella lays especial stress upon the “neck” (lib. x, V, 380-389); in verse 234 he uses “ fragili cucurbita col/o” as a distinguishing term; in verse 380 he uses young, in the manner of a squash, but is usually grown for ornament. These char- acters, as given by Columella, all apply to Lagenaria vulgaris, and not to Cucurbita maxima. Palladius (lib. 1v, C. 9) describes the zeck or bottle form, and the uses as utensils, and does not indicate their use as food. Pliny (lib. XTX, C. 23) describes a fruit called melopepo, shaped like a quince and of recent introduction. His refer. ence to color, odor, and their dropping from the stalk when ripe, would seem to in- dicate our melon. In lib. xIx, C. 24, he speaks of the climbing habit of the Cucur- bita of one kind, and the weight of the fruit so heavy that the wind does not move it, and yet attached to a small stalk; of variable shape, sometimes long like a ser- 660 Kitchen Garden Esculents of American Origin. [July, and the frequent descriptions and mention@by botanists and trav- elers after the discovery of America. Naudin, the authority on this genus, refers all the forms of the cultivated pumpkins and squashes to four species, Cucurbita max- ima, C. pepo, C. moschata and C. melanosperma. The three first forms of these are in French culture, and Vilmorin describes thirty-two varieties! Of the eighteen varieties under C. maxima, eight have their American origin indicated by name or statement ; of the five varieties under C moschata, two have American names; of the nine varieties under C. pepo, three have an Ameri- can origin indicated by name. The historical record does not seem to change this numeration in such a way as to indicate that C. maxima is more native to Europe than is C. pepo. We may, however, trace the appearance of such forms of this vegetable as we have data for, and we shall find that America has contributed very largely to the varieties, The word pumpkin seems to have been transferred to our cucurbits from the Greek pepon, “a gourd or melon not eaten till quite ripe,” Aristoteles,? or the Latin pepo, “ a species of large melon or pumpkin, Pliny? but the word does not occur in Scrip- tores Rei Rusticz veteres Latini of Gesner, which indicates how little known was the pepo in Italy where now the pumpkin is so common, and where it so early appeared after the discovery of America. The word squash seems to have been derived from the -pent, even, says our chronicler, occasionally nine feet long. He evidently refers ~ next to the Benincasa, which he has confounded with the gourd, for he says it is ~ covered with a white bloom, especially as it grows large. There is not a word here to indicate a pumpkin of any kind; the whole wording may apply to Lagenaria vulgaris in its varieties, except the last, which fit Benincasa cerifera. To one who hand, the references of our authors will be seen to apply very closely to the Lagen- aria varieties figured therein; sufficiently so for a clear identification, taken with the context; and to apply sof af a// to any of the Cucurbita varieties therein figured and described under Cucurbita maxima, While upon Latin authors we will take occasion to note that neither Columella nor Palladius reckon the Saseolus or phaseolus, which some writers have taken to kidney-beans, among garden plants, but class with field crops, and Virgil classes with the vetch as a cheap food. The directions for planting are to sow the seed, six pecks per acre, in the autumn, Hence their Jaseolus must have been a hardier plant than our kidney-bean, and mot our bean. Apicius’ receipt for cooking and Pliny’s mention would apply equally well to a Dolichos as to a Phaseolus, Les Pl. Pot., 171-186. Liddell and Scott’s Greek Dict. ’ , 2 -T Andrews’ Lat.

In New England’s Crisis, a poem by Benjamin Thomson, in 1675, we find: “ When Cimnels were accounted noble blood, Among the tribes of common herbage food,” The word cushaw is Indian, and is derived from ecushaw of Heriot, 1586. It was applied to a bluish-green, white-streaked large pumpkin by Beverly,’ and the description applies to the Puritan squash of Burr, and also to a Florida squash grown at the N. Y. Agr. Exp, Station, in 1884, from seeds obtained from the Seminoles in Florida. The word cuckaw is now used asa synonym of the winter crookneck of New England, and cushaw or cashaw to a Southern form of like character, both of which have two forms, one of which is the form of the Puritan and Neapolitan grown at Naples, the other crooknecked. It is inter- esting to note that courge de la Floride is a French synonym of the Neapolitan’ The popular grouping of this class of vegetables does not con- form to the scientific. Gregory? offers the definition in use: “Grouping all the running varieties together, we express the marketman’s idea of a squash, as distinguished from a pumpkin, when we say that all varieties having soft or fleshy stems, either with or without a shell, and all varieties having a hard woody stem, and without a shell, are sguashes. While all having a hard stem and a shell, the flesh of which is not bitter, are pumpkins - and all of this latter class the flesh of which contains a bitter 1 Roger Williams’ Key, &c., 2?

[July, principle, are gourds.” An examination of a more complete set of varieties than the marketman uses, however, shows that this classification is not always correct. The popular use of the terms seem to be, sguashes are those forms used on the table; pump- kins those forms that are grown for stock and for use in pie making ; gourds are Lagenaria vulgaris, and have white flowers. It is thus seen that the popular word as used now would be as misleading as are the popular words used by the early explorers. De Candolle is willing to grant that C. pepo is American, but is uncertain about C. maxima. He says, however, that seeds, certified by M. Naudin to belong to this species, have been found in the tombs of Ancon,a conclusive circumstance if the date of the latest burials at Ancon were certain. The Brazilians had, however,a name for this plant, Jurumu, and Pickering” quotes a Carib name, Jujuru or abora’ but Schomburgh! gives adodoras as the Brazil- ian name of C. pepo L. It is the Pepo maximus indicus compres- sus of Sloane (1707), Cucurbila pepo Aubl. Sloane’s name being the same as used by Lobel, 1581 (?).° In traditionary relations the large pumpkin appears in Mexico, for Bancroft® says: “In the golden age of Mexico, during the reign of Quetzalcoatl, pump- kins were said to measure a fathom round.” Pickering’ says that “melones” too large for a man to lift, some of them internally yellow, were noted by Oviedo’ in the West Indies. The “ moth” squash belongs to this section, and Loudon records a weight attained of 245 lbs., and a “ mammoth chili” was exhib- ited in New York in 1884 by a seedsman, which weighed 223 lbs. In 1857 one weighing 264 lbs. was exhibited at the Califor- nia State Fair, and one weighing 313 lbs. is said to have been shown at the Smithfield Club Cattle Show in Liverpool? Messrs. Asa Gray and J. Hammond Trumbull” seem to have offered suffi- cient reason to believe that all the pumpkins and squashes are of American origin. I may only add therefore some horticultural evidence. 1 Piso. Brazil, ed. 1658, 264; Marcq., ed. 1648, 44. Chron. Hist. of Pl., 709. 3 Desc. +Hist. of Bar., 593. i _5De Candolle, Geog.

Porter, and representing C. maxima in the list of squashes. In 1885, in one seed catalogue five varieties of pump- kin, twelve varieties of sguash and four of summer squash; of these squashes seven belong to C. maxima, and the Valparaiso is not included. The Hubbard is said by Gregory, its introducer, to be of unknown origin, but to resemble a kind which was brought by a sea captain from the West Indies; it was distributed in 1857. The marblehead came from the West Indies, and was dis- tributed about 1867 ; the autumnal marrow or Ohio appeared in — 1832; the Butman in 1875. Not one variety of this class seems to have originated in Europe, although pumpkins of this species are found there in numerous forms, but most of them in general characters of form of fruit can be duplicated from the varieties of traditionary origin in New England. Vernacular names count for little, but the citrouille troguois applied to a French pumpkin of this species would add support to the tradi- tionary belief that pumpkins of like nature formerly existed among the Northern Indians. Molina, 1787,’ mentions “ the yel- low flowered or Indian gourd, called pexca, it is of two kinds, the common and the mamillary This last in its leaves and flowers resembles the first, but the figure of the fruit is spheroidal, with a large nipple at the end; the pulp is sweet, and its taste is very similar to a kind of potato known by the name of camote,” a description which will only apply to the varieties of the squash of the turban character. . It would seem as if the burden of proof was upon botanists to show the Asiatic origin, or a knowledge of the pumpkin and squash before the voyage of Columbus, before rejecting the American evidence as inconclusive. - Purslane. — Gray and Trumbull are inclined to believe that Purslane was in the new world at the time of the discovery. Oct. 28, 1492, Columbus saw “ verdolagas” on the north shore of Cuba Oviedo, writing about 1526, enumerates among native plants of Hispaniola “verdolagas and pertulaca,’ and in 1525 mentions the abundance of “verdolagas.” Jean de Lery in Bra- 1 Gregory, Squashes, 1867.

[July, zil, 1557, mentions “pourpier.” Sagard-Theodat, speaking of the country of the Hurons, speaks of pourpier or pourcelaine being a common weed of their cornfields. These quotations are from Gray and Trumbull’s article, Am. Pour. of Sc., April, 1883. Champlain, in 1605, speaking of the Indians of the Maine coast: “ They brought also some purslane, which grows in large quantities among the Indian corn, and of which they make no more account than of weeds.”! Josselyn, about 1672, speaks of it in Massachusetts, and Cutler, 1785, mentions it in cornfields, and as eaten. Hawkins, 1593, at Cape Blanco, So. America, found upon the rocks “ great store of the hearbe purslane,” which he collected for the refreshment of his sick.* _ While it is not certain that these authorities all meant Portulaca oleracea in their mention, yet it would appear very strange if such a common weed of cultivated lands of the old world had not been well known and recognized. Purslane, in one variety, yet finds sale among the seeds of our seedsmen among potage herbs. Claytonia perfoliata Don. is called in France Claytonia de cuba, and pourpier d’hiver ; in Spain verdolago de cuba.* Sweet Corn.—All the forms of maize are of American origin. The early history of the sweet or garden form-species is very obscure, although the peculiar appearance and rich edible quality of its sweet kernel would presuppose quick and flattering recog- nition from the first comers. Sweet corn is said by some to have been brought by Lieut. Rich- ard Bagnoll from Gen. Sullivan’s expedition against the Six Nations in 1779, and to have been called papoon corn. The anonymous writer in the New England Farmer (Sep. 7, 1822) under the pseu- donym “ Plymotheus,” says: “ That was the first of the species ever seen here, and since that time it has been more and more diffused ; and I believe within a few years only, has been generally and extensively cultivated for culinary purposes.” In another communication (Aug. 3, 1822) it is said to have been found during = Sullivan’s expedition “among the Indians on the border of the Susquehanna.” Another account’ says it was found by Sullivan’s 81.

Sweet corn is neither mentioned nor hinted at in Jefferson’s Notes on Virginia, written in 1781. Timothy Dwight applied the synonym “ shriveled corn,” usually called “ sweet corn,’ and says that “maize of the kind called sweet corn was the most delicious vegetable while in the milky stage of any known in this country. At New Haven the sweet corn may be had in full per- fection for the table by successive plantings from the middle of July to the middle of November.’ Dwight traveled in New York and in New England in 1817 and before, and was in Yale College in 1795. (This quotation was contributed to me by O. P. Hubbard, New York.) Bordley? says: “It has appeared to me that the sort called sweet corn (having a white shriveled grain when ripe) yields stalks of richer juice than the common corn.” Sweet corn is first mentioned for sale, so far as we have seen, in Thorburn’s seed catalogue of 1828, one kind only, the sugar or sweet being named. It is not spoken of by name even in his Gardeners’ Kalendar for 1817 or 1821, nor in M’Mahon’s Ameri- can Gardeners’ Calendar, 1806, nor by Gardiner and Hepburn, 1818, nor in a Treatise on Gardening," 1818, nor in Fessenden’s New American Gardener, 1828. In 1829 several ears of a “new variety ” from Portland, Me., were exhibited before the Massachu- setts Horticultural Society. Bridgeman mentions one variety in 1832; Buist, in 1851, speaks of two varieties, but Salisbury, — 1848,' describes three, and Bement,’ 1853, two sorts. In Schenck’s Gardener’s Text-book, 1854, three varieties are named. In 1863 Burr describes nine, and in 1866, twelve sorts, In an illustrated article of my own, contributed to the Rural New Yorker for 1884, thirty-five varieties are described as distinct, and thirty-two are figured. : Sweet corn is not mentioned in Noisette’s Manual Compleat du Jardinier, 1829, not by Bonafous in his folio work published in 1836, so we may assume it had not reached French culture at the latter date. In 1883 Vilmorin names seven sorts, all of which are American named. 1 Travels, 1821, I. ? Husbandry, 1801, 3 John Randolph. + Trans. N. Y. Ag.

[July, Sweet Potato—We do not hear of the sweet potato until after the discovery of America.’ Clusius, in 1566, first saw them in Spain, and Oviedo records their introduction from the West Indies. Ramusio’s Collection of Voyages was published 1563-74, and in the Portuguese pilot’s relation, therein published, is, “ The root which is called by the Indians of Hispaniola atata, is named igname at St. Thomas [coast of Africa], and is one of the most essential articles of their food.’* The igname was mentioned at St. Thomas by Scaliger, 1566. It was grown by Gerarde in England in 1597, and is figured by Rheede as cultivated in Mala- bar, and by Rumphius in Amboyna, the latter asserting that they were brought by the Spanish Americans to Manilla and the Moluccas, whence the Portuguese diffused it through the Malay archipelago. In China Bretschneider tells De Candolle® that according to the Chinese books the sweet potato is foreign to China, and that the Min-shu published in the sixteenth century, says that the introduction took place between 1573 and 1620. In America they are noted by many of the early voyagers, from Columbus onward. Asa Gray and Trumbull, Am. Four. of Sc., April, 1883, have collected the evidence. We may add to their references that Chanca, physician to the fleet of Columbus, in a letter dated 1494, speaks of age or sweet potatoes or yams as among the productions of Hispaniola, and Pigafetta Vicentia, 1591, found in Brazil dazatas, “ they resembled turnips and tasted like chestnuts.” Peter Martyr’ describes many varieties, as does also Oviedo® and Garcilasso de la Vega,’ this fact of variety indi- cating antiquity of culture. Gray and Trumbull state that it had reached the Pacific islands 1! One exception may be noted, but I have not opportunity of studying into the authenticity of the statement. In a Spanish MS., 1562, in the island of Palma, by John de Abreu de Gallineo, a Francisan friar, an account is given of the voyage of Betancon to the island of Ferro (Canaries) in 1405. ‘Their food was the flesh of goats, sheep and hogs; they had also some roots which the Spaniards call batatas.” The identity of the roots appears to rest u upon the opinion of the writer in 1562, after the introduction of the sweet potato and the American name _ ® Hist.

I can find nothing which can countenance this belief except in the number of varieties that are cultivated in some islands, as thirty- three in the Hawaian islands." The name cuma/a in New Zea- land, and Otaheite,? and Fiji kumara’ is strangely like the cumar of the Quito dialect* We may add here that the camote of Yucatan was called in the islands azz and datatas, Tomato.—Tomatoes were eaten by the Nahua tribes, and were called fomat/, and also by the wild tribes of Mexico,’ and Her- nandez® has a chapter “ De tomatl, seu planta acinosa vel Solano, and describes several sorts under their Mexican name.’ It was described by various European botanists of the sixteenth century, which indicates its introduction to Europe, and for this botanical history we may refer to Gray and Trumbull already cited. It seems to have been grown in European gardens as a fruit, from its first introduction, judging from the references in Dodonzus” and Gerarde," but Parkinson, 1656, speaks of it as grown in Eng- land for ornament and curiosity only. In Italy Chauteauvieux, . 1812, mentions their cultivation, on a large scale, for the Naples and Rome market. It is probable that their use was at first more . general among southern nations, as we find that the Anglo-Saxon races were the last to receive them into the kitchen garden. Thus in 1774 Long” describes the fruit well, and mentions their often use in soups and sauces, and adds that they are likewise fried and served up with eggs. In 1778 Mawe and Abercrombie” mention five varieties as known, two of which are described as scentless and burnet-leaved, and add that they are eaten by the Spaniards and Portuguese in particular, and are in high esteem. In the United States its introduction preceded by many years its use as we at present know it, It is said to have reached Phil- 1 Wilkes, U. S. Ex. Ex., Iv, 282. 2 Cook’s Voy., I, 199. 3 Seeman, Fl.

[July, adelphia from St. Domingo in 1798, but not to have been sold in the markets until 1829. It was used as an article of food in New Orleans in 1812.1 The first notice of it in American gardens was apparently by Jefferson,’ who notes it in Virginian gardens in 1781.’ It was introduced into Salem, Mass., about 1802, by an Italian, but he found it difficult to persuade people even to taste the fruit? Among American writers on gardening, M’Mahon, 1806, men- tions the tomato, but no varieties, as “in much esteem for culi- nary purposes ;” Gardiner and Hepburn, 1818, say: “make excellent pickles ;’ Fessenden, 1828, quotes from Loudon only ; Bridgeman, 1832, says, “ much cultivated for its fruits in soups and sauces.” They were first grown in Western New York in 1825, the seed from Virginia, and in 1830 were not produced by the vegetable gardeners about Albany,‘ yet directions for culti- vating this fruit appeared in Thorburn’s Gardeners’ Kalendar, 2d edition, New York, 1817. Buist writes that as an esculent plant in 1828-9 the tomato was almost detested, yet in ten years more every variety of pill and panacea was “extract of tomato.” Mr. T. S. Gold, secretary of the Connecticut Board of Agriculture, writes me that “ we raised our first tomatoes about 1832, only as a curiosity, made no use of them though we had heard that the . French ate them. They were called love apples.” D. J. Browne,’ 1854, describes six varieties and says, “ the tomato until within the last twenty years was almost wholly unknown in this county as an esculent vegetable.” In 1835 they were sold by the dozen in Quincy market, Boston” In the Maine Farmer, Oct. 16, 1835, in an editorial on tomatoes, they are said to be cultivated in gar- dens in Maine, and to be “a useful article of diet, and should be found on every man’s table.” In a local lecture in one of the Western colleges about this time, a Dr. Bennett refers to the tomato or Jerusalem apple as being found in the markets in great abundance, and in the New York Farmer of this period, one person is mentioned as having planted a large quantity for the 1 Prairie Farmer, June 28, 1876. 2 Notes, Trenton, 1803, 54-5. *¥Felt’s Annals of Salem, 11, 631. +Autobiography of Thurlow Weed. ® White, Gard. for the South, 312. € Pat.

Manning.” The summing of the above evidence seems to be that the escu- lent use of the tomato in America does not antedate the present century, and only became general about 1835 to 1840. At the present time sixty named varieties appear in our various seed catalogues, but many of these are synonyms. Of the sixty-four named varieties grown at the New York Agr. Exp. Station in 1883, over fifty may be called sufficiently distinct for garden pur- poses. The tomato can escape from cultivation quite readily and be- come feral. In the fall of 1884 I saw “ wild” tomatoes growing upon the rocky sides of a railroad cutting in New Jersey, a few miles from Jersey City, and these resembled the red cherry. Unger? refers to their occurrence on the Gallapagos islands. Wilkes‘ mentions several sorts in the Feejee islands, but whether wild seems doubtful from the reference. On Ascension island they are said to have become completely established all over the island,> and Grant mentions their occurrence in Central Africa, 7° 21’S.,and near swamps 4° to 5° S., the natives not yet having learned their-edible quality.® We have now completed our list of American kitchen garden plants, which includes the alkekengi, four species of dean, one species of cucumber, Jerusalem artichoke, martynia, two nasturtt- ums, peppers, potato, pumpkin and squash, purslane, tomato, sweet corn and sweet Mien. From the list of kitchen esculents recog- nized by Vilmorin; we can add the pine apple, quinoa, Apios tuberosa, aracacha, pea nut, ysano, claytonia, spilanthes, enotheria, strawberry two species, hop and oca in two species. Of these the pineapple and strawberry are rather to be regarded as fruits, the Apios seems rather to be included as a desirable plant for trial than as actually cultivated, and the hop is a native of both worlds, ; 1 Me.

[July, MOURNING AND WAR CUSTOMS OF THE KANSAS. BY THE REV. J. OWEN DORSEY. OW, as the Kansas are few, all the men of the tribe assemble and go on the war path; but formerly it was not so. Then a sufficient number of warriors could be raised from a few gentes, probably among the gentes connected with the deceased by blood or marriage. Then a-pipe was given to one who was an impor- tant man in the tribe; and he fasted for six days before summon- ing the warriors to foi him in the expedition. An account of the ceremonies observed at the death of Hosa- sage, a Kansas, in the winter of 1882-3, will show the present customs of the tribe. The authorities from whom the informa- tion was obtained were the war captain of the tribe, Paha®le- gaqli; Waqube-k’i", the chief of the Eagle gens, and Nixiidje- yifige, the principal sacred man or doctor of the tribe. As soon as Hosasage died, his father-in-law, Wakanda, went after Paha*le-gaqli, the war captain. The old man said, “ Hosa- sage is dead. Therefore I have come to tell you to take the sacred pi The reply was, “ Yes, I will take the sacred pipe. I will also take the sacred bag.” Wakanda returned home, reaching it as day was coming. Paha"le-gaqli took the mysterious objects, and put clay on his face as a sign of mourning. He fasted, per- forming the ceremonies of the ancients. At day he took the pipe and went to the house of the deceased. Hosasage’s affini- ties had laid out the corpse, placing the body in the house near the door, and with the head to the east. A skin tent was erected outside, extending from the front of the house towards the east. Representative men from all the gentes entered the tent and took their stations, as in the accom- panying figure, beginning with Nq 1. When Paha*le-gaqli arrived he first stood at C. Then the body was brought from the house and placed at B, with the head to the east. Then Paha"le-gaqli stood at J), where he wept a great deal for the dead. He could not touch the corpse or any other _ dead body. After mourning for him a long time, he said, “ I will sit still for 3 = four days, smoking the sacred pipe. Then will I wander about, : and I will kill any animals that I find.” _ Then he condoled with all pr present. After which Wakanda took the ghost (sic) from the ps 2 and carried it back to the moue, crying as he went.

All are Yata men, 2. e., men from gentes on the left side of the tribal circle. They were called djexe-k’i", or het- ile-carriers, answering to the Osage jsexe-k’i.

The directors consulted one another, saying, “ Let us go on the war path in four days.” Then they addressed Paha*le-gaqli for the first time in their official capacity, “O war captain, let us go on the war path in four days.” Then Paha*le-gaqli announced their decision to all the others present, saying, “ O comrades! in four days I will go on the war pa ' Asa reward for his services Waksude gave Pahatle-gaqli & spotted horse, two red blankets, two white ones and a calico shirt.

[July, cept Paha"le-gaqli, returned to their homes. Paha"le-gaqli could not go to his home for four days. He had told the kettle-carriers to make him a small lodge by the course of a small stream which used to flow near his house. This was done by Gahia-ma"yi" and Tcehawale. Paha™le-gaqli was required to fast, wandering about and crying in solitary places, having clay on his face. At sunset his brother, Ijuka-gaqli, brought him water. Then could the mourner ` wash his face and drink a cupful of the water, but he could eat no food. After sleeping awhile at night, he arose and put more clay on his face. At sunset on the fourth day the four directors went to the house of Paha*le-gaqli and sent the four kettle-carriers to summon the mourner to his house. Then was he permitted to take food. The next morning he went for Gahia- mayi” and Tcehrwale. Before they arrived he and his wife left their house. He ordered thêm to invite the guests to his lodge. The messengers went in different directions, saying to each in- vited guest, “ I have come to call you to go on the war path.” And each man replied, “ Yes, I will go with you.” A lodge was set up near the house of Paha"le-gaqli, and there the guests as- sembled. Only two gentes met as such, the two Hafiga gentes, Black eagle and Chicken-hawk, but there were present the directors and kettle-carriers, some of whom were members of other gentes. The following figure shows the seats of the Hajiga men in the lodge: Chicken-hawk men, Black eagle men. 2. Ali*kawahu, 1, Paha*le-gaqli. Jf. Cu™mikase. b. Thuka-gaqli g: Wat? li>, c.

Two young men, one of the Turtle gens and one of the Qiiya (Eagle) gens, attended to the sacred boiling (for the feast). Paha*le-gaqli sent Tadje-k’uwe for the sacred clam shell, saying, , Fig. 3. “ I will take the large covering and the large bowl too. Iwill perform a sacred ceremony. Go for them.” These objects were at the house of Paha”le-gaqli, beyond the person addressed. The clam shell had been brought from the “ great water at the east” by the ancestors of the Kansas. This was the case with all the sacred objects of the tribe, including the pipes and sundry roots used as medicines. The shell was opened and made like the face of a man, with eyes, teeth, etc. The above sketch was made by Paha"le-gaqli. 674 Mourning and War Customs of the Kansas. [July, When the sacred pipe is smoked by a Large Hafiga (Black eagle) or a Small Hafiga (Chicken-hawk) man, he must hold it in his right hand, blowing the smoke into the clam shell, which is held in his left. The smoke is supposed to ascend to the thunder- god, the god of war, to whom it is pleasant. There are five envelopes or wrappings for the shell, similar to those around the war pipe. All of the wrappings are called the “ i"he-cabe.” The inmost one is the bladder of a buffalo bull; the next is the spotted fur of a fawn; the third is matting made of the tall grass called sa; the fourth a broad piece of deer skin; the outmost one is interwoven hair from the head of a buffalo bull.

Ali*kawahu took the bundle and began the sacred song. Paha"le- gaqli soon joined him in the singing. The accompanying chart used by these singers is a fac-simile of one drawn by Paha*le-gaqli, who copied it from one he inherited from his father and father’s father. There used to be many other pictographs on it. The Osages have a similar chart, on which there are fully a hundred pictographs. Paha*le-gaqli said that there should be a representation of fire in the middle of his chart, but he was afraid to make it. The songs are very sacred, never being sung on ordinary occasions, or in a profane manner, lest the offender should be killed by the thunder-god. Fig. 1 the sacred pipe, Waqube wakandagi. Three songs refer to it. They are sung when Ali*kawahu removes the coverings. One is as follows: “ Ha-ha’! tce’-ga-nu’ ha-ha’! Ha-ha’! tce’-ga-nu’ ha-ha’! Ha-ha’! tce’-ga-nu’ ha-ha’! Hü-hü’! (Said when the envelopes are pressed down on. Chorus—Yu! yu! yu! Hü-hü’! Hi-hii’! (Sung by all the Black eagle and Chicken-hawk men.) This chorus is an invocation of the thunder-god. In making it the arms are held up to the sky, being apart and parallel, with the palms out. Each arm is rubbed from the wrist to the shoul- der by the other hand! After the singing of these songs, Paha®- le-gaqli receives the clam shell and puts it on his back. Fig. 2, Ts‘age-jifiga wayt", (Two) songs of the venerable man or Wakanda, the maker of all the songs. When Ali®kawahu and Paha"le-gaqli are singing these two songs, they suppose that he walks behind them, holding up his hands to the thunder-god in prayer for them. On the special occasion referred to in this paper, the expedition after the death of Hosasage, when these songs had been sung, Paha"le-gaqli shifted the shell from his own back to that of Jifiga-wasa, one of the directors. He then ordered another man, Tayé, to put the Ihe-cabe on his back. 1 This song and invocation is used by the Ponkas. 676 Mourning and War Customs of the Kansas.

All the men had picketed their horses outside the lodge be- fore the singing of the songs, and they had brought in their saddles, After the singing Paha®™le-gaqli lighted and smoked the war pipe, and then handed it to all the others. After smoking they slept there. When the sky was getting light, before sunrise, the men took clay which they rubbed over their faces. All rose to their feet within the lodge and cried. They ceased crying when the sky became white. They went out, put the saddles on the horses, mounted them and departed. Paha®le-gaqli kept far be- hind the others. All cried. By and by they reached the other side of the Arkansas river; then they reined in their horses and dismounted. Paha*le-gaqli took the clam shell and gave it to one of the four directors to carry on his back. Subsequently they killed five prairie chickens. Thus was life taken, and the mourners were satisfied. They went on till they reached a small stream, beside which they encamped. A fire was kindled and the two kettle-carriers who had made the small lodge at the first, went for water ; they gave water to all the warriors, who washed off the clay from their faces. They ate the prairie chickens and then started homeward. All returned to the house of Paha*le- gaqli, where his wife put a kettle on the fire and gave them a meal. All partook of it and then separated, going to their respec- tive homes. According to Nixiidje-yifige, two qlets‘age were chosen for each side of the tribe. They carried on their backs thread or sinew for mending their moccasins, and corn and squashes in 678 Mourning and War Customs of the Kansas. [July, bags. The war captain had a tobacco pouch of skunk skin. — When he smoked he was ever praying, “O Wakanda! I wisha Pani Loup to die !” The war captain made one of the qlets‘age carry the sacred bag before the ceremony of “ waqpelé gaxe” was performed. On this occasion there were six kettle-carriers instead of four. When the qlet s‘age carried the sacred bag two of the kettle-carriers carried a bundle of sticks apiece, which they laid down on the road, one end of each bundle pointing towards the land of the enemy. Four of the kettle carriers remained still. The next morning all the warriors went to the spot; they drew a circle around the bundles and set up one stick within, which they at- tacked as if it were a Pani. This might cause, in their opinion, the death of real foes. Members of the Lu, or Thunder gens, could not take part in this ceremony, but were obliged to keep in the rear. The following prayers were said during the wapgqele gaxe, according to Nixiidje-yifige: “I wish to pass along the road to the foe! O Wakanda! I promise you a blanket if I suc- ceed!” This was said facing the east. Turning to the west the following prayer was made: “O Wakanda! I promise you a feast if I succeed !” On the return from war, during the scalp dance which followed, the wife of the war captain held the scalp and the war pipe as she danced. ‘ U’ce-gu"ya, an aged man of the Black bear gens, told the fol- lowing: In former days when a man lost a child he cried for it, _ and became a war captain. Two persons built him a small lodge ~ and filled a small kettle with corn. When the corn was boiled, which was about dark, the captain gave a little of it away, but he ate none. He fasted because he wished to kill an Indian. The warriors departed the next day. The kettle-carriers took corn, meat, moccasins, small kettles and spoons. During the “waqpele gaxe” the following petitions were made. “ I wish to kill a Pani! I wish to bring back horses! I wish to pull down a _ foe! I promise you a calico shirt! I promise you a robe! I will _ also give you a blanket, O Wakanda, if you let me come home after killing a Pani!” ___ War Dances.—There are two dances before going to war, the aka” watci” and the Wacdbe watci”.

They divide into two parties of equal numbers and dance out of doors, around the village, half going in one direction and half in the other. Each of the four qlets‘age car- ries a standard or wagqléqle ska, made of swan skin (mi™xa-ha), Two of these men are in each party. The he wagleqle or wacabe, from which the dance takes its name, is borne by the wadjipa®yi® or village crier, a member of the Deer gens. When they start on the war path the qlet s‘age go horseback, carrying their standards. The two dances after returning from war are the Watce wa- tci? or scalp dance, danced by the women, and the Ilucka watci”, danced by the men alone. Other Burial and Mourning Customs-——When Wm. Johnson, a Kansas, died, he was buried by his wife, his sister and his sister’s daughter. As the widow did not wish any of the tribe to go on the war path, she did not send for Paha*le-gaqli. So neither he nor the other men assembled at the house of the deceased, as in the case of Hosasage. When a man’s wife dies, the husband must put earth on his face at daybreak, and wander about till sunset, bewailing his loss. He must fast from sunrise to sunset for a year and a half. After sunset he washes his face. and can eat and sleep. At the end of the period of mourning, the widower says to his wife’s brothers, “ I will give you a horse, a red blanket, a white blanket, a calico . 680 The Relations of Mind and Matter. [July, shirt and a kettle.” One of them replies, “Yes, my sister’s hus- band, that is good.” The presents are made the next morning at daybreak. The elder brother-in-law takes the horse, and the next receives the other gifts. At noon the widower washes his face and seeks another wife. In like manner when a woman loses her husband she must put earth on her face and fast during the day from sunrise to sunset for a year. She too can eat after sunset. At the end of the year she brings the gifts to the sister and younger brother of her hus- band. The sister gets the horse and the brother takes the rest. When a widower does not make presents to the kinsmen of his deceased wife before marrying again, he is sure to provoke the anger of his brothers-in-law. Formerly an old man took a gun and shot at his sister’s husband for this reason. And another man, when the Kansas were south of Council Grove, Kan., took a knife and gashed the head of the offending man in several places. Therefore widowers are accustomed to observe this rule of making presents, fearing the punishment which their offended affinities might inflict on them. :0: THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS, (Continued from p. 542, June number.) IJ. THe Nervous MECHANISM. I all the higher animals a system of fibers and cell masses forms the channel by which external energy enters the body, and is distributed to its every organ and tissue. There is consid- erable variation of form and condition in this apparatus, but it is essentially a single organic agent, and includes the muscles as part of its organism. There is little apparent differentiation in the fibers. The main differentiation is in the endings of these fibers. Of these endings a very great number exist on the sur- face of the body, where they are variously modified and adapted to different purposes. These are the receiving organs, through whose aid external energy reaches the conducting fibers. They a are varied to receive every form of external energy. This energy beats upon the surface of the body in at least six forms or modes. : One of these is that known as ethereal vibration, through which far distant objects make themselves felt, Part of these vibrations b 1885.] The Relations of Mind and Matter. 681 enter the body through a specially organized nerve apparatus, the rods and cones of the eye. But they all, as radiant heat, enter at every part of the surface, by aid of less specialized nerve endings. Heat in another condition, the static vibrations of con- tiguous matter, also enters at every part of the surface, presuma- bly through the same channel. A second series of vibrations, those of ponderable matter, enter by the channel of the ear, through the aid of an intricately organized apparatus. In addi- tion to these three conditions of vibratory influence there are three modes of direct contact through which motor energy also makes its way into the body. These are solid, liquid and gase- ous contact. Gaseous contact enters by a special channel, that of the nerves of smell, which are excited by the touch of excessively fine material borne on the air current. Liquid contact finds its special channel in the nerves of taste, which are only sensitive to the direct touch of liquified or dissolved matter. Solid contact has the whole surface for its field. The nerves of touch, indeed, are also sensitive to liquid and gaseous contact if exerted by mat- ter in motion, but mainly respond to the contact and pressure of solid matter. The internal extremities of. the nerves lack the variety of their surface endings. They are distributing organs as the latter are receiving organs. The energy received varies greatly in charac- ter, and needs considerably varied apparatus for its reception. That distributed has become far more homogeneous and can be dispersed by a single apparatus. This is the muscle fiber, which, though not ordinarily considered so, is essentially but a nerve ending, an aggregation of unstable chemical molecules around the extremity ofa nerve. And the combined aggregates of these bers, which constitute a muscle, are but a mass of nerve extrem- ities ending in matter which is adapted to set free a considerable volume of motor energy. Into this matter the energy which has traversed the nerves is discharged, and there instigates an active chemical change and a rapid freeing of energy, with animal motion as its result. Such is reflex action, a frequent mode of nerve action in man, and possibly the only one in many of the lower animals. Motor _energy differing greatly in character and source is thus forced to produce a single effect, that of muscular contraction and animal 1See Organic Physics, AMER. NAT., Feb., 1883. 682 The Relations of Mind and Matter. [July mass motion. But in all the higher animals other effects are pro- duced. All the nerve fibers enter cells or masses of cells called ganglia, though there is no evidence that they end there. There is some reason to believe that they simply pass through these cells, with a reduction of diameter, and perhaps a division into branches. All we can be sure of is that the motor energy which they carry inward does not all pass through these ganglia, but that much of it is arrested in its course and there distributed. And in this distribution an interesting feature of the case is, at least so far as the cerebral ganglion is concerned, that the motor energy retains the peculiarities it possessed before entering the body, or something equivalent to them, and impresses a perma- nent record of each such peculiarity upon some internal tablet. Only when this energy continues its course over the nerves to the muscles does it lose its individuality and merge in the general outflow of muscle energy. As we descend in the animal kingdom it is to find this com- plex apparatus of sensation and motion gradually simplify. The sensory nerve-endings and their organs grow less intricate, and their susceptibility is diminished. Some of the organs of special sense completely disappear, and the power of the others becomes little more than a modified touch. In very many cases the body is covered by a rigid armor, and the influence of external energy is limited to a small region of the surface. Finally the special senses disappear, apparently the last to vanish being that of sight, which is reduced to a vague discrimination between light an shade. _The cerebral ganglion grows less and less marked, and disappears as a special organ. Finally the nerve and muscle fibers vanish, one of their last traces being the single cell which, in the Hydra, appears to function both as nerve and muscle. On reaching the Protozoa we find forms quite destitute of sensory and motor organs, And yet sensation and motion persist. These _ powers seem to be native to protoplasmic matter, however aggre- gated, and are displayed even in the plant cell wherever it is so situated that its protoplasm is exposed to external energy. Yet late discoveries in regard to the constitution ofthe cell _ prove it to be by no means the simple homogeneous structure : nd supposed, The division into nucleus and outer cell has bi traced to a very low level, and perhaps exists at the low- - Anad the nucleus, and to a less marked extent the outer a 1885.] The Relations of Mind and Matter. 683 cell, are now known to be heterogeneous in structure, composed of at least two distinct substances, one of which exists as very minute fibrils, of which the other occupies the interspaces. This organization, very well marked in the cells of the higher animals, becomes much less so in the Protozoa, and is only clearly distin- guishable in their higher representatives. Yet this is probably due to the imperfection of instruments and methods. The ner- vous structure has been only recently discovered in the Medusz, and has not yet been traced in the stem of the compound Ccelen- terates, though this conveys sensory impulses, and doubtless con- tains communicating fibrilla. In like manner the fibrillar struc- ture may exist in all cells, though not always sufficiently defined to be discoverable. Again the cilia, so common in the single-celled life forms and in many of the surface cells of higher animals, have been traced in some instances into direct connection with the fibrillz. Per- haps in all cases they are external continuations of the fibrillz, and may thus function as the primitive nerve-ending, the sensory termination which receives impressions of external motor energy and transmits it to the fibrillz to be distributed throughout the sub- stance of the cell. There is thus some reason to believe that the developed motor apparatus of the highest animal has its primitive counterpart in every cell, and that the unfolded nervous and mus- cular organism of man is but a direct development of that existing in the Infusoria. In Amoeba the pseudopod may function as a sen- sory organ and receive motor impressions which are distributed throughout the celi mass. Tissue contraction seems to be the general result of such motor influence, however received and dis- tributed. ý Fg N yeh OB: T ate eh Lamy eas Pi, Rg | motor apparatus. It has been clearly shown that fine threads of 3 protoplasm connect contiguous cells in frequent instances, servers have seen this structure in the cells of numerous species of plants, and some writers look upon it as universal in plant cells. In addition to the protoplasmic threads which join the nucleus to the cell wall, others pass through the wall, probably through minute apertures, and connect with the protoplasm of ` one or more neighboring cells. Possibly this, may be a result of cell division. When pir cell separates into two its protoplasm may not completely separate. And it is quite conceivable that 684 The Relations of Mind and Matter. [July, this net work of protoplasm, which connects all the cells of many and possibly the active cells of all plants, may have a nervous function, though the conditions of plant life are such as seldom to call it into exercise. . In animals a similar structure has been observed in many cases, and particularly between epithelial cells, where it is most likely to be called into functional activity. Some observers claim that it is general, and that the animal body is an intricate net work of fibrill2, of which the cells forms the nodes. This doctrine, though it has been strongly combatted, is certainly not without considerable support in observation, and there is good reason to believe that such continuity of protoplasm exists between the cells of at least several of the animal tissues. Thus the primitive motor organism quite probably exists with ‘little change throughout the highest animals, and may serve to bring every cell within the reach of motor influences, as the simi- larly minute vascular structure has a like result in regard to nutritive influences. The conditions here indicated, however, exist in very different degrees of perfection in different cells. In some tissues they may almost or quite have ceased to exist through lack of exercise. In nerve tissue, on the contrary, they are remarkably well developed. The large nerve cells of the ganglia possess an intricate fibrillar structure, so distinctly devel- oped that it was clearly recognized long before any one imagined that such a structure was a common feature of cells. And the extrusion of protoplasmic threads through the cell walls, in direct continuation of the internal fibrils, is equally well marked. The whole surface of some of the cells is covered with a series of fine nerve rootlets. Yet greatly developed as this structure is, there is no reason to doubt that it is a direct unfoldment of the general cell structure, with its nuclear and outer. cell fibrils and its one or more protoplasmic threads running to neighboring cells. In the case of nerve tissue the rootlets also connect with other cells, but the connected cells are often separated by very considerable inter- vals. Very likely this separation is a result of natural selection. In original Metazoa sensory impressions may have passed from ‘cell to cell through the aid of their connecting protoplasmic _ threads. In forms in which no nerves can be discovered this _ ‘method _ still continue, as a slow yet sufficient process. But nal life developed the connected cells seem to have become 1885.] The Relations of Mind and Matter. 685 more and more widely separated, the fibril growing thicker and becoming a nerve fiber, with the power of conveying motor energy more rapidly and in greater quantity. Through some such process successive steps of evolution may have led to the condition now existing in the highest animals, with very numer- ous fibrils emanating from the cells, their combination into bun- dles with an insulating covering, and their final distribution to distant cells, For this idea we have a degree of embryological warrant, and can trace the nerve organism to one of its ancestral stages. For, as observed by Beale, the cells from which the nervous system arises form processes which connect adjacent cells together. They are thus direct counterparts of many, and perhaps of all, tissue cells. As growth goes on these cells separate, while their con- necting processes lengthen and form the axis cylinder of the nerve fiber. In this we seem to perceive the phylogenetic devel- opment of nerve tissue. Eventually, as some observers consider, one of these cells becomes a cell in a nerve ganglion, the other a peripheral end organ, their connecting process being lengthened out into a nerve fiber. That in this we have an exact representa- tion of the mode of development of nerve tissue, however, is far from certain. If so we should find each nerve fiber proceeding directly from one to the other extremity without intermediate ganglia. The frequent existence of these ganglia leads to another conclusion, and indicates that the original development pursued another line, which has been slurred over in the rapidity of unfold- ment like so many embryological characteristics. Various hypotheses of the mode of development of nerve tissue have been heretofore offered, the most notable being that of Herbert Spencer, but these are mainly philosophical. Still another may be offered which is in direct consonance with the recent discov- eries in cell and tissue formation above described, and which _ future embryological research may fully substantiate. The hypothesis which we propose is the following. We have seen some reason to believe that in single-celled animals the motor impressions received by the cilia or otherwise are distrib- uted throughout the cell by the fibrille. This distribution is at first general, but in case of special motions may become special, certain fibrillæ becoming specially capacitated, through exercise in this function, to convey the current. In Metazoan animals VOL. XIX.—NO. VII. 45 686 The Relations of Mind and Matter. [July, the connecting threads of protoplasm between the cells are doubt- less competent to convey motor impulses from cell to cell, and they very probably preceded the development of nerves as a sen- sory arrangement, permitting a slow and general transmission of motor influences to every part of the body. But if any particu- lar motions became habitual, through natural selection, the sen- sory inflow must have become to some extent specialized, follow- ing certain channels of conduction more frequently than others. But nutrition always attends activity, and in these special lines the fibrils must have grown larger and more capable. If their labor still increased, a second change must have succeeded. e line of special conduction being mainly composed of cells, with short interconnecting fibrils, a modification necessarily took place in the cells also. If the outer threads had continuous fibrillar connection through the cells, which we have some warrant to assume, these cell fibrilla must have grown larger and straighter as a result of extra nutrition and natural selection. They may, indeed, have exhausted the cell nutriment and caused the abor- tion of the remaining filaments. In short, a continuation of this process of evolution may have caused the gradual disappearance of most of the cells in the line of conduction, and the conversion of their fibrillæ into direct continuations of the developing nerve fiber. The make-up of the axis cylinder of every nerve fiber is in strong corroboration of this idea. It is found to consist of numerous extremely delicate fibrilla imbedded in a finely granulated sub- stance. Nuclei are also found in it. Thus it is closely analogous to the cell in composition, and presents strong indications of originating in a connected line of cells. Another feature of the nerve fiber is an interesting confirmation of this. The medullary sheath seems but a special elongation of the outer layer of the cells. It does not exist in the primitive nerve, of which we have probably a survival in the nerves of the sympathetic system, It seems the result of a fuller development, yet the fatty and albu- minous matters of which it consists are the substances which : exists most abundantly in the outer cell layer. Conversion into - matter is a general characteristic of deteriorating cells. Thus ie every Portion of the nerve fiber can be traced directly to the . cell, with singularly little change, and there is certainly much Teason to believe that nerve conduction is an outgrowth of a 1885.] The Relations of Mind and Matter. 687 primitive connected-cell conduction. All these cells did not dis- appear or suffer conversion. Some were retained, perhaps as cen- ters of distribution, by whose aid a single inflowing current could be sent off in several directions as a partial survival of the origi- nal general distribution. And significantly, near these cells the axis cylinder is naked. The cell matter has not been converted into a medullary sheath. Yet more significant indications of such an origin of the nerve system are seen in the bipolar nerve cells. In these a nerve fiber enters the cell on each side, and its fibrillated structure is clearly continuous with the fibrillæ of the cell. And in many cases the medulla of the fibers is continued over the cell. Such a cell, therefore, appears to be a survival of the primitive nerve, and indicates its origin, as above conjectured, from a line of cells with protoplasmic fibrillar connections, - There is one more point here to consider, that of the termini of the nerve fibers, It is quite probable that they never terminate in the ganglionic cells, not even in those of the cerebrum, but that they connect with the fibrillæ of these cells, which in their turn connect with outgoing fibers. Nor is it by any means sure that they have actual termini in the peripheral and muscular cells. - Indications point to the contrary. In many cases they seem to pass continuously through these cells and rejoin the exterior nerve fibrils, or to end ina plexus whose fibrille are probably ‘continuous. Thus in the highest development of nervous tissue there is singularly little change in structure from the condition of undifferentiated cell tissue. We may look upon the function of the nerve fibers as simply conductive, though it is possible that they add to the strength of the motor current through chemical change which takes place in their tissue. What is the function of the nerve cells? Very probably their action resembles that of the electric resistance coil. In telegraphy by decreasing the diameter of the wire the passage of the current is resisted, and part of it loses its electric character. By suitable contrivances this checked current may be converted into heat, light, magnetism or other forms of force. In the nerve cells the minute fibrillæ over which the current must pass seem to have a similar function. Part of the motor energy is converted into some other form of force. It may become heat. It may outflow into the high-atomed muscle molecules and cause chemical change. Or it may assume some other condition, as it 688 ae The Relations of Mind and Matter. [July, very evidently does in the cerebral cells. There are possibly no actual nerve termini anywhere within the body, but simply occa- sional resistance nodes, in some of which a single inflowing cur- rent may be divided between several outgoing channels, but in many or all of which the current is checked and partly converted into some other mode of motion. It is not necessary here to go into any minute description of the nervous system. In man it is virtually double. In addition to the external sensory and motor system, there is a secondary system which is devoted to the needs of the digestive cavity and to other internal duties. These systems are similar in general make-up, consisting of ganglia and communicating fibers, which extend partly to muscles and partly to the epithelial layer. But they have marked differences. The sympathetic has no central ganglion answering to the cerebrum. Its operations are all per- formed without consciousness except through the occasional aid of its cerebral nerve connections. And in its nerve fibers the axis cylinder is destitute of a medullary sheath. Some writers consider that its operations may have been originally conscious and have beccme unconscious and simply reflex through inces- sant repetition. Yet this is very doubtful. It presents every . appearance of being a survival of a primitive nerve condition, be- yond which it has not greatly developed. Consciousness is a con- dition that must have been originally vague and generalized, and which but slowly grew specialized with the gradual centralization of the nervous system. We cannot imagine it as retrograding and disappearing in any developing nervous system. In fact, the system of intestinal nerves has never become centralized and defi- nite. Such consciousness as it may possess retains its original vagueness. Its functional existence is perhaps as ancient as that of the external nerve system, but its development has been much slower. When the latter had advanced to the condition of dis- tinct nerves and ganglia, the former yet remained in the primitive stage of cell conduction. The nerves of external sensation have gained an insulating sheath while those of intestinal sensation remain naked. The one has become definitely centralized while the other yet lacks special organization. These results flow from _ their difference of duties, which in the one case are simple and unvarying, in the other complex and excessively varied, As a result such consciousness as may exist in the intestinal system 1885.] The Relations of Mind and Matter. 689 retains the dim vagueness which probably exists in animals of a very low grade. But in the cerebro-spinal system consciousness has become sharply centralized and defined. The peculiar condi- tion which we call consciousness may have its roots very low down in the soil of nature as a highly generalized accompaniment of motor energy. In.the evolution of higher forms and condi- tions it has grown steadily more specialized, until, in the central nerve organ of man, it has become a concentrated, developed and sharply defined condition, the necessary accompaniment of an equally special centralization of substance and energy, which we name the mind. The cerebro-spinal nerve system in man and the higher ani- mals has become a highly differentiated and complex organism, whose make-up may be very briefly described. The sensory nerves, which convey motor impressions from the various points of the surface, pass through a series of spinal ganglia in their upward journey toward the brain. .Here they enter the great ganglia at the base of the brain, to which the nerves of some of the special senses pass directly. From here they communicate with the cerebrum, though whether directly or indirectly is not certain. It is certain that when the cerebrum is removed many of the sensory nerves are found to be in direct communication with those of motion. It is almost equally certain that in ordi- nary cases many sensory impressions are directly passed on to the motor nerves, with or without consciousness. These inter- mediate ganglia, then, may perform a special duty in the economy which we will consider further on. From the cerebrum motor nerves enter these ganglia, from which the same or other motor nerves emerge and pass onward, mainly by the route of the spinal . ganglia, to the muscles. According to M. Luys! the cerebral organ is composed of a vast array of fibers which diverge to enter a hemispherical sheet of gray or cellular nerve matter. This gray sheet is greatly wrinkled and folded so as considerably to increase its superficial extent. It is of no great thickness, and is composed of succes- sive layers of nerve cells connected by fibers, these cells being smaller in the surface layers and growing larger in the deeper layers. The hemisphere is really a double mass, since it is divided in the middle line of the body, the two halves being con- 1 The Brain and its Functions, International Scientific Series. 690 The Relations of Mind and Matter. [July, nected by a thick commissure of nerve fibers. The cerebral cells are pyramidal in shape, the summit of the pyramid being directed upwards. Each of these cells gives off a delicate fringe of fibrils like the fine rootlets of a plant, which spread out in an inter- laced network and form a continuous fine plexus. These fibrils are believed to be the origin of the sensory nerves, becoming aggregated and covered with a medullary sheath. In addition to the processes which thus break up into rootlets of protoplasm, - there is always one at least which does not thus subdivide but continues as.a defined nerve fiber from the cell outward. This is believed to be the origin of the motor nerves. The above beliefs, however, as yet need substantiation in discovery. Midway in the cerebral organ, occupying the center of the hemisphere, are two oval-shaped bodies, known respectively as the optic thalamus and the corpus striatum. Each is composed of several ganglia, the first being connected by nerve fibers with the posterior, the second with the anterior portion of the spinal chord. These, according to the hypothesis of M. Luys, are in- termediate stations for the nerve currents. All the sensory nerves of the body are gathered into the ganglia of the optic thalamus, from which they are again distributed to the cerebral lobes. The return nerves from these lobes are, on the contrary, gathered into the corpus striatum, from which they are distributed to the mus- cles of the body. It is not necessary to give the somewhat ques- tionable conclusions which he draws from this mechanism of the cerebral nerve system. If now we trace the nervous system downward through the different classes of the animal kingdom, its complexity of organi- zation is found to gradually decrease. A head ganglion, sending off nerves to the organs of special sense, is found to exist in the- arthropods and the higher mollusks and annelids, but it has lost _ the distinctive features of the vertebrate brain. There is no longer a separate cerebral organ above, and only connected by fibers with, the ganglia which directly receive sensation and control motion. Only the analogue of the basal vertebrate brain seems to exist in these lower animals. In the Vertebrata the cerebrum = . may be removed without detriment to the functions of animal life, and possibly without entire removal of consciousness. In this Condition a vertebrate animal may be in nervous analogy with = normal condition of the lower animals mentioned, though 1885.] Editors’ Table. 691 from lack of dependence on its lower head ganglia, in the normal state, these possess no specialized powers of consciousness. At a still lower level in the animal world all clear indication ot nervous centralization disappears. Ganglia still exist but perhaps only as agents to draft off the sensory currents of energy to the various muscles. There probably exists a vague consciousness, but no condition that can be called psychical. The nerve system in these creatures has sunk to the level of the sympathetic in man, Still lower every trace of a nervous system vanishes, though probably continuous lines of cell protoplasm yet exist ex- tending generally throughout the body. This condition can be traced down into vegetable life, and particularly into the Alga, whose generalized cell substance and lack of indurated covering renders every portion of them subject to the inflow of external energy. The fibril of the cell thus seems to be the germ of the nerve apparatus of the fully developed animal, It may be noted in conclusion that in the hypothesis of nerve development here advanced is avoided the necessity of the ‘long and intricate explanation of nerve genesis offered by Herbert Spencer. In this view the nerve fibril is a constituent part of every cell, and the nerve and muscle function of conduc- tion and contraction is performed by the Protozoa. In all ani- mals of the many-celled character the protoplasmic connection between the cells functions as the primitive nerve fiber, and each cell as a primitive ganglion. Nothing further than development of this primordial apparatus is requisite as the animal race develops, _ And even in the most highly developed nervous system the line of . its phylogeny is evident in the mode of formation of the fiber, and the character of its connection with the ganglion cell. All that is further requisite is conductive specialization, the restriction of each special impression to a special line of conduction. And natural selection has doubtless been the agent in producing this effect. : (To be continued.) :0:— EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D.

In persons who cultivate it in this way it has a sentimental as well as an intellectual origin. 692 Editors’ Table. [July, Sometimes this is the desire for “ more light;” in others it is the love of the beautiful in thought and in nature. In all minds it comes from brain-hunger, which may be the craving of a rational mind for a rational explanation of phenomena, or the mere neces- sity for grist felt by an ever-running conscious mill. To such minds money is only valuable as it enables them to satisfy these needs, and the gratification of such a mind-thirst is more to them than money can bring in any other direction. So it is with the true artist. The sensitiveness to the beautiful in nature or in idea, must find expression in proportion to its intensity, and in so doing it finds its reward. These are phases of the intellectual life which, if our race follow the usual course of evolution, are to become far more general than they are at present. It is very de- sirable that they should become more general, for they furnish sources of pleasure that cannot be obtained in any other way. The sentiment that loves knowledge is akin to the divine, for its sustenance is truth, and error is discarded at whatever sacrifice. It has faith enough in the order of the universe to see its inner- most secrets unfolded, for unsuspicious of evil, it does not expect ` to find it predominant. It breathes good will to men, for it feels sure that with full knowledge evil may be avoided so as to be practically destroyed. In such a pursuit human nature is enno- bled ; and to respect our kind is to crown human intercourse, and to elevate social life to an ideal level. What are the tendencies of society in this direction in our .country? Is it not time to repeat the verity that “a man’s life consisteth not in the abundance of the things which he possess- eth?” Does the accumulation of material property constitute the highest achievement of the human mind? Does the care of _ the appurtenances of mere living constitute the noblest occupa- tion of man? An affirmative would seem to be the verdict of the present generation in many places. We hope this state of things may not last. The hunger and thirst of the full-grown soul will demand satisfaction, and will some day fling aside the less worthy ideas which its larval stage have imposed upon it. It will more and more emerge into a fuller understanding of its relations to = the universe, and a corresponding appreciation of its privileges _, andits duties.

The changes are most numerous in chapter 1, which is devoted to a discussion of the microscope. Here the student will find much valuable and interesting matter. We cannot refrain from quoting, for the benefit of our makers of microscopes as well as the younger botanists, the remark of Hugo Von Mohl: “The simpler the construction of the micro- scope is, the more easily and more quickly will one accomplish all the necessary movements. The more complicated the con- struction the more will they cost in time and reflection, and the more will the attention be distracted thereby during the observa- in vain to prepare a usable specimen ” (p. 8).

GEOGRAPHY AND TRAVELS! Arrica.— The Sahara—Dr. Oscar Lenz has published his work on “ Timbuktu” and is preparing to set out on a new expe- dition. His exploration of 1879-80 comprised (1) Marocco and the Atlas ranges as far as the Draa basin, and (2) the Western Sahara. Dr. Lenz traveled with only two interpreters and a trusty Maroccan attendant, yet thanks to a letter of recommendation from the Sultan of Marocco, and his assumption of the character of a Mussulman physician, he passed safely through the fanatical tribes on the route. The stony and sandy tracts of the Western Sahara are produced by the weathering of sandstone, quartz and carboniferous limestones, and have a mean elevation of from 800 to 1000 feet. Dried-up watercourses, with deep eroded channels, radiate from the central highlands north and north-east to the Mediterranean, east to the Nile, south to the Tsad and Niger, and west to the Atlantic. The conclusion seems to be that up to comparatively recent times the Sahara was a well-watered and wooded region, mostly inhabited by pastoral and agricultural communities, the descendants of more primitive peoples who were contemporary with Palzolithic and Neolithic man elsewhere. In the Taudeni district, about 20° N., under the meridian of Tim- buktu, Dr. Lenz found some well-worked greenstone implements. Gerhard Rohlfs has found similar objects as far east as the Kufara oasis south of. Tripoli. The Asiatic camel is a comparatively recent intruder. The crocodile still survives in many of the pools and lakelets which here and there mark the course of mighty Streams. Dr. Lenz believes the desiccation to have taken place during the historic period, and attributes it largely to the reckless destruction of the woodlands. As vegetation disappeared so did moisture, the large fauna became extinct, and the settled popula- tions were succeeded by nomad Berbers and Semites. The forti- fications of Timbuktu were razed upon its capture by the Fulahs in 1826, and since then it has been a purely commercial town, but a constant bone of contention between the Tuariks and the Fulahs, which levy dues but leave the administration ir the hands of the Kahia. Dr. Lenz affiliates the Fulahs to the Nubas, but A. H. Keane, in his review of the work, in Mature, considers this _anerror. The Fulahs are distinctly non-Negro, and Dr. Lenz _ Notices the resemblance to Europeans of full-blood specimens. ~ M. Giraud’s Expedition —M. V.

The harvest is in June, but in three months the crop is consumed, and during the rest of the year they live on wild honey, roots, fungi and wild fruits. At this season the paths are strewn with corpses. M. Giraud believes that the population is always decreasing. The only two metals found were iron and copper. It must be remembered that M. Giraud had a most dis- couraging experience. Recent Acquisitions of Spain. —Spain has Lappe acquired a siderable territory in Africa, comprising the west coast of the Sahara between Cape Bogador (20° g’ N.) a Cape Blanco (20° 45’ N.), both included; and in the Gulf of Guinea the coast line from the Muni river, which forms the northern boundary of the French possessions on the Gaboon, to the Rio Campo (0° 43’ to 2° 41’ N.). Six stations have already been established on the Sahara coast, and all points giving access to shipping will be permanently occupied, Old treaties with the chiefs on the Rio enito have been renewed, with a view to prevent the threatened advance of the French in that direction. The Kingdom of the Congo.—The limits of the new “ Kingdom of the Congo,” as recognized by the late Berlin conference, appear to be as follows: On the Atlantic seaboard from Banana point to Yabé (5° 45’ S. lat.), then by one parallel of Yabé to the mer- idian of Ponta da Lenha, by this meridian north to the Chiloango, then to the source of that river, thence to the Mtombo-Mataca falls of the eongo, leaving to the French the station of Mboco, but reserving Mucumbi and Manyanga, then along the Congo to its confluence with ‘the Bumba beyond the equator, where the boun- dary running north-west remains to be determined. The south- ern frontier follows the Congo from Banana to a point a little above Nokki, the south bank belonging to Portugal, then on the parallel of Nokki to the Qwango, along this river to about 9° S. lat., and thence in a diagonal line across the continent to Lake Ban eolo. Eastwards the boundary coincides with the West coast of lakes Bangweolo, Tanganyika, Muta-Nzighe and Albert Ny- anza. Within these limits the new State will have an approxi- mate area of 1,000,000 square miles and a population of probably 40,000,000, mostly of Bantu speech and Negro or Negroid stock.

According to the “ Geographie Universelle,” of Reclus, the area of this tract is about 54,000 square miles, and its population about 00,000. It is practically a desert, and its inhabitants are the nomad Danakil and other similar tribes. There is very little water, the chief river being the Hawash, which runs into lake Aussa, and then forms a brackish lake called Abhebad, about sixty-five miles from Tajura. The stream issuing from this lake fails to reach the sea, and terminates thirty-six miles from Tajura. Obock, the French possession outside the straits of Bab-el-Man- deb, has sixty-two miles of coast, and an area of 1470 square miles. It has not as yet any attraction for settlers, since it is without water, cattle, or vegetables. The first can, however, be procured from the Hawash basin, and cattle can be brought from Somali- land. The real drawbacks are the situation and character of the harbor and its position fifty or sixty miles from the route to India and the East. Sagallo, thirty-seven miles from Obock, has also been ceded to France by the local sultan. This place lies on the road from Ankober, the capital of Shoa, to Tajura, the chief place of export of King Menelik’s country. King Menelik, according to M. Bramond, dreams of railroads through his dominions, and of steamers on the Hawash to Lake Aussa. The territory of Assab, now in the hands of Italy, includes the bay of that name, with all its islands and the coast line from Ras Darmah, the eastern point of the Bay of Beilul, in N. lat. 13° 14’ to Ras Sintiyar, the south-east point of the Bay of Assab, in N. lat. 12° 53’. The belt of territory purchased from the local sul- n by Italy is from two to six miles wide and thirty-five miles ong. African News.—From the remarks of Mr. J. M. Cook, who has recently returned from Dongola, it appears that the cataracts of the Nile are not correctly placed upon the map. The so-called third cataract at Hannek is no cataract at all, only a very small rapid. Between the second and so-called third cataracts four or five cataracts occur, and these explain the delay in the concentration of the British troops at Dongola. From Sarras to Sakarmatta (seventy-four miles), the rise was 450 feet. A fresh expedition in Somali-land has been undertaken by Messrs. F. L. and W. D.

GEOLOGY AND PALAONTOLOGY. Str WīiLLIAM Dawson ON THE Mesozoic FLORAS OF THE Rocky MOUNTAIN REGION OF Canapa.’—In a previous memoir, published in the Transactions of the Royal Society of Canada, Vol. 1, the author had noticed a Lower Cretaceous flora consist- ing wholly of pines and cycads, occurring in the Queen Char- lotte islands, and had described a dicotyledonous flora of Middle Cretaceous age from the country adjacent to the Peace river, and also the rich Upper poker flora of the coal formation of Vancouver’s island—comparing these with the flora of the Lar- amie series of the Northwest Territory, which he believed to constitute a transition group connecting the Upper Cretaceous with the Eocene Tertiary. The present paper pekebréed more particularly to a remarkable Jurasso-cretaceous flora recently discovered by Dr. G. M. Daw- son in the Rocky mountains, and to intermediate groups of plants between this and the Middl e Cretaceous, serving to extend greatly our knowledge of the Lower Cretaceous flora, and to render more complete the series of plants between this and the Laramie. The oldest of these floras is found in beds which it is proposed _to call the Kootanie group, from a tribe of Indians of that name who hunted over that part of the Rocky mountains between the 49th and 52d parallels. Plants of this age have been found on the branches of the Old Man river, on the Martin creek, at Coal 1 Read before the Royal Society of Canada, May, 1885. 700 General Notes. .

They may be traced for 130 miles in a north and south direction, and form troughs included in the Palæozòic formations of the moun- tains.

Some of these cyca- daceous plants, as well as of the conifers, are identical with spe- cies described by Heer from the Jurassic of Siberia, while others occur in the Lower Cretaceous of Greenland. The almost world- wide Podozamites lanceolatus is very characteristic, and there are oy aie ; nail e been found in these beds, whose plants connect in a remarkable way the extinct floras of Asia and America end those of the jurassic and Cretaceous periods, Above these are beds which, with some of the previous spe- cies, contain a few dicotyledonous leaves, which may be provis- ionally referred to the genera Sterculia and Laurus; and still higher the formation abounds in remains of dicotyledonous plants . of which additional collections have been made by Mr. T. C. Weston. The beds containing these, though probably divisible into two groups, may be named the Mill Creek series, and are approximately on the horizon of the Dakota group of the United States geologists, as illustrated by Lesquereux and others. The species are described in the paper, and differ for the most part from those of the Dunnegan group of the Peace river series, which is probably of the age of the Niobrara group, and, of course, still more from the overlying Laramie group. With regard to the latter, the author adduced some new facts confirmatory of his pre- viously expressed view as to the position of the Laramie at the top of the Cretaceous and base of the Eocene, and also tending to show that some of the plants still held by certain palzo-bot- anists to be of Miocene age are really, in Canada at least, fossils of the Laramie group, and consequently considerably older than is currently supposed. The collections of plants studied by the author had, for the most part, been placed at his disposal by the director of the Geological Survey. THE SYNCARIDA, A GROUP OF CARBONIFEROUS CRUSTACEA.— The following are the conclusions of a paper read at the last meeting the National Academy of Sciences.

The lack pf a carapace, even a rudimentary one, and the homonomous Segmentation cause them to bear a resemblance to the Edriop- thalmata which they would not otherwise present. To the Isopoda Acanthotelson presents a superficial resem- blance, due to the slightly vertically-compressed body and the homonomous segmentation. The Edriopthalmata (Arthrostraca of some late authors) are defined by Claus as “ Malacostraca with lateral sessile eyes, usually with seven, more rarely with six or fewer separate thoracic segments, and the same number of pairs of legs; without a carapace; but this does not express those dif- ferences in the form of the antennz the thoracic legs and abdom- inal appendages especially those of the end of the urosome or abdomen, which are characteristic of the sessile-eyed Crustacea as distinguished from the Thoracostraca. From the Isopoda in which the body is usually broad and ver- tically flattened, with seven free thoracic segments, while the abdominal legs are lamellar and closely appressed to the short abdomen, our Acanthotelson plainly differs in the long biflagellate decapod-like first antenne; in the long homonomously ringed abdomen and schizopodal abdominal feet and especially the schiz- _ opod-like telson and last pair of feet, adapted as in the shrimps for striking the water from above downwards. The Amphipoda are in general characterized by their laterally 46 VOL XIX.—NO. VII, 702 General Notes. [July, compressed body with lamellate gills on the thoracic feet and an elongated abdomen, of which the three anterior segments bear the swimming feet, while the three posterior has posteriorly directed feet adapted for springing (Claus). Now if Acanthotelson is not an isopod, still less should it be regarded as related to the Amphi- poda. The first antenne are entirely unlike those of any known amphipod, in which there is a very short accessory flagellum ; the second antenne of Acanthotelson are strictly decapodous in ap- pearance and very different from that of the Amphipoda, whereas in Gammarus the scape is as long as the flagellum. Although there are seven free thoracic segments in Acanthotelson as well as in Gammarus and other Amphipoda, those of Acanthotelson pods is still more marked. The first five pairs of uropoda or abdominal appendages are in Acanthotelson all formed apparently on the same plan, not essentially different from those of schizo- pods, while the last pair are flat and on the same plane as the tel- son and intimately associated with the latter, in that these parts are formed on a truly macrurous plan and most approach those of the schizopods, in which the telson and rami of the last pair of feet are narrow and more or less acute at the end. There is nothing in the structure of the urosome and its uropoda in Acan- _ thotelson to remind us of the same parts in the Amphipoda. ae homologous with those of these two groups.

It is one of the quarto series of the United States Geological Survey, but the present edition was published, we are informed, by the author at his own expense. The mechanical execution of the book is good, and it will remain a monument to its authors. We confess, however, to surprise at not finding it, as we had anticipated, a monograph of the group. According to the synopsis of twenty-nine reputed material representing them has been obtained by Professor Marsh, but we have searched in vain for a description of the greater part of it in the work. The memoir is in fact of a rather general character, giving descriptions of the osteology of the two species Loxolophodon mirabile and L. ingens,’ with occasional references to others. It is evident that the greater part of the work of writing this monograph remains to be done. We should have preferred to have seen this magnificent opportunity improved, so that it should have embraced detailed aaah aus of those char- acters of all the species on which alone the derivation theor can be established or refuted. A taral result of this neglect is a failure to appreciate the true generic relationships of the species. There are no sufficient characters adduced for the gen- eric discrimination of the species included under the heads Dinoceras and Tinoceras, while the characters of Uintatherium are erroneously given. The distinct genus Bathyopsis is not ad- Professor Marsh thinks that the females of these animals had shorter canine teeth than the males, and that the protective man- dibular flange is correspondingly small in that sex. He also finds istana in the nasal tuberosities, and indicates that these also rger in male animals. re connection with the description of the brain of the Dinocerata, ever, fails to give Professor Lartet credit for the proposal of the general theory of brain development in the Mammalia with the progress of geological time The classification of. the Ungulata adopted is largely that of Cope, to whom no acknowledgment is made. A hypothetical group is proposed and defined as the primitive type of Ungulata. 1 The Dinocerata, By O. C. Marsh. 3 For the genera of Dinocerata, see NATURALIST, June, 1885. 704 General Notes. [July, Professor Marsh is apparently not aware that this group has been actually discovered, defined and extensively illustrated under the name of Condylarthra by Cope, and that its discovery was antici- pated on hypothetical grounds by the same author as long ago as 1874.1 The unwary reader may be still further impressed with the idea that all this is new, by the array of new names which are attached to these well-known natural divisions. The Condy- larthra figure under another name, and those of Amblypoda and Pantodonta are changed on the pretext that they are preoccupied, though Professor Marsh does not state when or how. examination has failed to reveal any real preoccupation. The nearest name to Pantodonta is Pantodon, a genus of fishes, and to Amblypoda is Amblypodia, an unused synonyme in Lepidop- tera. We do not believe, however, even were the names identi- cal, that a generic name can be preoccupied by the name of an order, or other mononomial word, or vice versa. The name Dip- larthra (the Ungulata of Gill and Flower) is changed for a new one, and other terms are employed for the time-honored and generally used Perissodactyla and Artiodactyla of Owen. We forbear comments, remarking only that even a handsome volume like this one will not suffice to obliterate history.” On p. 169, one is surprised to read the following statement: “No Cretaceous mammals are known.” Two species were des- cribed from the Laramie Beds of Dakota, two or three years ago. Professor Marsh corrects by implication a good many errors made by himself several years ago when criticising the work of another author on this group. Thus he adopts the species Zox- olophoden cornutus Cope, and no longer considers it identical with a species subsequently described by himself. But he cannot avoid making a misrepresentation as to a photograph of this spe- cies of which a few copies were circulated at the time of its dis- covery. The statement that the canine tooth was attached to the skull by a plaster base so as to increase its apparent length is erroneous. The tooth was made to adhere to its base by a piece gures which have since appeared, is apparently designed to substantiate this statement. Professor Marsh, moreover, does not recede from the erroneous position he took at that time on the question of nomenclature, but still uses generic names which have been repeatedly shown to have no right to exist if the ordi- 1885.] Geology and Paleontology. 705 nary rules of nomenciature are observed.’ The history of the subject is concealed from the reader by the omission of reference in their proper places to the papers which antedate those of Pro- fessor Marsh, and by the omission of the dates of their publica- tion when they are referred to.” This work will always be valuable for the descriptions and plates which it contains, and with the abatements we have already pointed out, we recommend it as the handsomest work on the subject yet published. —E. D. Cope. GEOLOGICAL News.—General—From a paper recently read by W. H. Hudleston at the meeting of the Geologists’ Association it appears that the ‘‘ Nubian sandstone” comprises the strata be- tween the crystalline rocks and the Upper Cretaceous ; the lower sandstone and overlying limestone of Wady Nasb is Carbonifer- ous; the middle division is Cenomanian, is widely extended in Egypt, occurs in great force at Petra, and constitutes the cliffs on the east side of the Dead sea; while the Lebanon division is prob- ably well up among the Cretaceous limestones and possibly on the horizon of certain ligniferous beds occurring at Edfou on the Nile. The crystalline rocks are in two series, a lower (referred to the Laurentian) penetrated by dykes of granite and diorite; and a second series consisting mainly of porphyries permeated by dykes of feldspar and basalt. All the Nile cataracts occur where the river passes over such crystalline areas, while the tranquil stretches are upon the Nubian sandstone. The Cretaceous lime- stones are in Syria more important than those of Eocene age, but in Egypt the latter are much the thickest. The Cretaceous beds u | horizons (Zittel). Neither in Palestine nor in Egypt is there any sharp line of demarkation between the chalk and the Tertiary rocks. The celebrated Jebel Usdom or Salt mountain of the Red sea, is assigned to the Cretaceous by Dr. Lartet, but to the marls of the Dead Sea basin by Hull. Zittel states that the palaonto- logical boundary between the chalk and the Eocene is clearly defined, despite the continuity of the marine deposits. The sea hollow is undoubtedly an independent lake basin of high 1 We take the present opportunity to refer to some similar cases of hypersensitive- ness to be. fo und in Professor Marsh’s papers on the Dinosauria.

[July, antiquity. The watershed separating it from the southern por- tion of the Arabah is 660 feet high, while the highest point of the Vale of Jezreel is only 285 feet. Marl deposits exist in the Dead sea basin at an elevation of 1400 feet above the present Dead sea level, and the old marls of the Jordanic lakes are not entirely unfossiliferous, as three Melanidæ have been found in them. Silurian.—Figures of the now celebrated fossil scorpions found in the Silurian rocks of Scotland and Gothland by Dr. Hunter and Professor Lindstrom, are given in Mature (Jan. 29), and Mr. - N. Peach gives in the same number a compendium of our knowledge of these ancient air-breathers. The first Paleozoic scor- pion found was described in 1835, by Count Sternberg, from a specimen obtained in the coal formation of Chonile, near Rad- nitz, in Bohemia. Three years later Corda described another (Microlabis) from the same locality. In 1866 Messrs. Meek and Worthen described two new species from the Coal Measures of Mazon creek, Illinois. In 1873, Dr. H. Woodward showed that the genus Eoscorpius (one of those found at Mazon creek) occurs in the English Coal Measures and in the Carboniferous limestone _ the present age. Mr. Peach asks, What were the victims of these ancient murderers? The dragon-flies of the Middle Devonian of New Brunswick were thought to be the oldest land animals until Mr. Peach, in 1882, showed that chilognathous myriapods were far from uncommon in the Lower Old Red Sandstone of Forfarshire, in Scotland. There is but a short step from this to the Silurian, and M. Brongniart has found in the Silurian limestone of Calvados a fossil Blatta. Perhaps a habit of feeding on the eggs of animals left bare by the tides may account for the embedding of these air- reathers in marine strata. Devonian —Hystricrinus carpenteri, a crinoid with articulating spines, is described by G. J. Hinde in the Ann. and Mag. Nat. Hist, March, 1885. “The genus is identical with Arthrocanthus (Williams), a name preoccupied among the Rotatoria. Apart from the possession of articulating spines it is near Hexacrinus.

D. Walcott (Amer.. Your. of Science, April, 1885) describes Mesonacis, a new genus of Cambrian trilo- bites, intermediate between Paradoxides and Olenellus, the head and first fourteen segments being of the type of the latter, while the pygidium and ten posterior segments more resemble the former. The fifteenth segment fits snugly against the fourteenth, and has a long, slender spine extending to the pygidium. Meso- nacis vermontana occurs in the Georgian of the State it is named after. Carboniferous—MM. Renault and Zeiller have described a number of mosses from the carboniferous strata of Commentry (France). The mosses previously found in a fossil state have been few, and of the Tertiary epoch, principally Miocene, but the Com- ` mentry beds contain many impressions of their stems, three or four centimeters long, some simple, others with alternate fronds. The stems are usually united in tufts. The absence of any trace of the organs of fructification prevents the determination of the place of these fossils in present classifications, but MM. Renault and Zeiller think they belong rather among the acrocarps than among the pleurocarps. and J. W. Kirkby give, in the Ann. and Mag. of Nat. Hist. for March, a synopsis of the species of the ostracodous genus Kirkbya, eleven in number. Most of the specimens are from marine shales associated with the calcareous beds of the Carboniferous series. Tertiary.— Mr. J. W. Judd has shown that in the Western isles of Scotland there occur a number of peridotite rocks which are the central cones of Tertiary volcanoes of vast dimensions. These Tertiary peridotites are intimately associated with the gabbros and dolerites, and present numerous variations both in structure and mineralogical constitution. Among them occur examples of the rocks which have received the names of dunite, picrite and lher- zolite. Dr. C. J. Forsyth Major (Quart. ‘Jour. Geol. Soc., 1885) gives a list of thirty-nine species of fossil Mammalia found in the Val d’Arno. Not one of the members of the rich fauna found in the Mediterranean region and as far east as the Siwaliks of India, and existing on the boundary line between the Miocene and Pliocene, is found in the Val d’Arno, though the two ante- send the Machairodus and the Mastodon, are closely allied. s Mediterranean fauna occurs at Casino, near Siena, and the kaviat T e Hons of the Val d’Arno was also spread as far as India. The shore deposits of the Pliocene sea in Italy are said by Dr. Major to contain the same mammalian fauna as the lacustrine deposits of the Val d’Arno. The Post-pliocene fauna exhibits several connecting links with the Pliocene, oe Bg Italy “at least, not a single species of the older fauna seems to have gone over, as such, to the younger fauna.

American MEDICINAL PLAnts.—We recently noticed the first fascicle of this work, by Dr. Millspaugh, as worthy of patronage. in examination of the second fascicle confirms our favorable opinion. The illustrations are very good, and will not only serve admirably their purpose of enabling the medical student to recog- nize the various species of medicinal plants, but they will be found of value to the teacher or student of ordinary botany. In the second fascicle there are colored plates of Actea spicata, Carya alba, Cephalanthus occidentalis, Cypripedium pubescens, Equisetum hyemale, Fuglans cinerea, Mitchella repens, Thuja occi- ` dentalis, Viola tricolor, etc., etc., thirty in all. DEVELOPMENT OF STOMATA OF THE OAT.—Before the stomata appear the epidermis is composed of quadrangular cells, which afterwards grow much faster in length than in breadth. The mother-cell of a stoma is cut off from the end of one of these cells, and sometimes each cell in a row furnishes a stoma (Fig. | 1a). This mother-cell rapidly increases in size, and large masses of protoplasm touching the cell soon become evident in the cells adjacent to the sides (Fig. 1 4 6). This gathering of protoplasm IS preparatory to the formation of accessory cells, which are a first nearly semicircular, and are cut out of the adjacent cells, one on each side of the mother-cell (Fig. 244). The central and accessory cells now enlarge in about the same proportion until the former divides into two guard cells (Fig. 4); after this the accessory cells encroach upon the guard cells until in the mature stoma the latter are narrower through the center than at the ends ; and the width of the whole four cells is but little more than of one single epidermal cell (Fig. 6). The behavior of the protoplasm is very characteristic, the gen- _ eral rule is as follows: The mother-cell and the accessory cells are both at first full of rich protoplasm. In the accessory cells this tends to condense in the center; vacuoles first appear in the = ends of the cells (Fig. 3), these increase in size with the develop- a : __ * Edited by ProrEssor CHARLES E. Bussey, Lincoln, Nebraska, oe ON ee ae RS ae Se ee PLATE XXIII. 1885. ] Botany. 7II ment of the stoma (Fig. 4), and in the mature stoma the visible protoplasm consists merely in a large nucleus in the center of each cell (Fig. 6 66). In the mother-cell one or two vacuoles may appear in any place, one central vacuole is perhaps the most frequent form (Fig. 3), but when division takes place a band of thick protoplasm stretches across the center of the cell (Fig. 4 a). Instead of condensing this tends to extend through the length of the cells leaving vacuoles only in the extreme ends (Fig. 5 a a). In the immature stoma this protoplasm is very slightly granular and has a slight green tinge, as if chlorophyll is being formed (Fig. 5); but in the mature stoma it appears perfectly homoge- neous, and small chlorophyll bodies which show the presence of | starch on application of iodine, occupy the former vacuoles. A cross-section, made before the mother-cell has divided, shows very thin walls (Fig. 7), but a section of a mature stoma repre- sents the guard cells as having thick walls, and I think it proba- ble that most of the protoplasm has been absorbed in the thick- ening process (Fig. 8).. This behavior of the protoplasm varies some in different stomata, especially in the stages represented in Figs. 3 and 4, but the process described prevails, and seems to be typical. The methods of finding the different stages of development are very simple. If the leaves of a growing plant be unrolled until the youngest is reached and the base of this used, it will show the youngest forms. It is useless to attempt to remove the epi- dermis, for the leaves which would contain the undeveloped stomata are too tender to permit it. Soaking the young leaves in a two per cent salt solution for about ten minutes aids in show- ing the formation of the accessory cells, if an examination is made immediately.—Zffie A. Southworth, Bot.

Repeated trials under different conditions showed that at the instant the sensitive surface was touched, the basal third of the wings and keel became strongly curved, and that this brought so great a tension upon the stamen-tube and pistil that the latter could not be held longer by the petals, as a bow when bent too far snaps its string and frees itself. The purpose of this ingenious mechanism is obvious. When the stamens spring out with such violence they throw the pollen forcibly against the body of any insect hovering over the flower or resting upon its wings and keel.— Charles E. Bessey.

A few synonyms are given, enough to enable one to use the catalogue in connec- tion with the older manuals. A summary at the end of the vol- ume gives the whole number of genera in the United States as 120, and of species 675. Following the catalogue proper is a synopsis of the tribes of North American grasses based upon and Hooker’s arrangement in the Genera Plantarum. Two years ago the same author published a somewhat similar catalogue in which there were 114 genera and 589 species. We will repeat what we have said several times already, that work of this kind coming from the Department of Agriculture at Wash- ington tends to raise the value of the department in the eyes of the scientific men of the country. 714 General Notes. [July, ENTOMOLOGY. UNUSUAL NUMBER OF LEGS IN THE CATERPILLAR OF LAGOA.— Lagoa crispata Pack. is an interesting moth forming a connecting link between the Dasychiræ (Orgyia) and the Te represented by Limacodes and its allies. As marked in our Synopsis of Bombycidz (1864): “When we observe the larva we would easily mistake it for a hairy Limacodes larva, for like them the head is re- tracted, the body is short, and the legs are so rudimen- tary as to impart a gliding motion to the caterpillar when it moves,” After describing the transformations, we Lagoa. added: “There are seven pairs of abdominal or false legs, which are short and thick. The first pair of enay or true legs are much shorter than the two succeeding pair Two years ago we found the fully fed caterpillars aa also those before the last molt on scrub-oaks in Providence, and again noticed them while walking, then carefully examined them after placing them in alcohol, and again examined the specimens during the past winter. It is well known that caterpillars have no more than five pairs of “proplegs,” “false legs” or abdominal feet, as they are variously called; and so far as we have been able to learn the present caterpillar is the only one which has additional legs, even though rudimentary. As in all lepidopterous larvez, there are ten abdominal segments, In the larve before the last molt there is a pair of rudimentary abdominal legs on the second abdominal segment, forming soft tubercles about one-third as large as the succeeding normal feet; the crown of hooks was wanting, but a tubercle on the anterior side corresponding to a similar one on the normal feet had five or six well marked stout spines, also two or three scattered ones in the middle, the tubercle being rounded, convex, not flattened at the end. On the sixth segment, following the fourth pair of normal ab- dominal legs, is a pair of tubercles like those on the second seg- ment and exactly corresponding in situation with the normal legs; situated externally are two long straight spines, but none homo- logous with those forming the crown. At the base in front of each tubercle is a tuft of sparse hairs, and on the outside is a chitinous spot bearing a dense tuft of hairs; these two tufts pre- cisely agree in Saton and appearance with those at the base of normal abdomin In the fully fed caterpillar the tubercles are exactly the same. It thus appears that in the Lagoa larva the first abdominal segment -is footless; the second bears rudimentary feet; segments e bear eime ; the seventh bears a pair of rudimentary legs; ts eight and nine are footless, while the og bears the ip developed asal or fifth pair of genuine propleg = While eei two pairs of tubercles differ from z normal legs 1885.] _ Entomology. 715 in being much smaller and without a crown of curved spines, they are protruded and actively engaged in locomotion, and in situa- tion, as well as the presence of the basal tufts are truly homolo- gous with the normal abdominal legs. etc., the larve are at first geometriform, having but three pairs of proplegs; in the geometrids there are but two pairs, while in the Cochlidise there are not even any rudimentary feet, thoracic or abdominal. As we have elsewhere observed, the primitive lepidopterous larva must have had a pair of feet on each abdom- inal segment, and may have descended from Neuroptera-like forms allied to the Panorpide as well as Trichoptera—A. S. Packard. USE OF THE Pup& oF Morus IN DISTINGUISHING SPECIES.—In describing the pupz of certain moths we have found it well to observe and note with care the shape and appendages of the ter- minal spine of the abdomen. This has been done to some extent, but our experience teaches us that there are, inta great number of cases, excellent specific or at least generic characters in these parts. In the Bombycidz, the Notodontians especially, and in the Geometridz as well as the Phycinz and Tortricidz, there are notable differences between those species which do or do not spin a cocoon, the latter attaching themselves by a mass of silk to the leaves, the spines and sete giving them a firm hold. In those living among leaves or in the earth, the spine is provided with long curved sete arising from the end and sides of the spines; - these vary much, as does the abdominal tip in general in different species of Acrobasis, according as they live simply between leaves or in a cocoon. In some Notodontians which make a cocoon, as in Lophodonta angulosa, the tip of the abdomen is blunt, ending in a rounded knob, with no rudiment of a spine. Dalana ministra the obtuse tip of the abdomen is divided into a stumpy short bifid spine, each division ending in two spines, with an external shorter third minute one at : In Edema albifrons the tip proper ends in a short spine, which is flattened vertically, deeply cleft, with tubercles, from which arise 3—4 curved setz on each side, the entire apparatus retaining a firm hold on the end of the mass of silk by which it adheres to e leaves. In the pupa of Lochmeus tessella the tip is flattened vertically 716 General Notes. [July, and very deeply cleft, each fork ending in a short lateral excurved hook, but with no setæ. This form lives in a slight cocoon, where it has no need of hooks. In Bombycidz, such as Eacles imperialis, which enters the earth and makes no cocoon, the use of the large caudal spine is as plain as in the pupz of the Sphinges; so also in the species of Anisota and Dryocampa. In the Geomtrids and Tortricids there are, in the abdominal spine and hooks, excellent generic and specific characters, as I have found in different species of Teras, etc—A. S. Packard. SWARMING OF A DunG-BEETLE, APHODIUS INQUINATUS.—About the first of last October, while riding along a country road near Ripon, my attention was attracted to a dark mass of living matter in the road. On examination it proved to be a host of Aphodius inguinatus, engaged with horse dung. They were in two or three masses, whose areas averaged perhaps three square feet each, and were piled up two or three deep. So many, too, were flying about in the air that as I rode along I could, with a single motion of the hand, catch from two or three to half a dozen. Nor were they confined to this one place, for they appeared in considerable num- bers at a distance of at least a mile from the point at which I first noticed them.— C. Dwight Marsh, Ripon, Wis. INSECT PESTS ON THE PaciFic Coast.—California seems to be fields in Alamada, Napa, Sonoma and Solano counties are being very seriously injured by the Hessian fly, an insect which has hitherto been supposed not to occur on the Pacific coast. Pro- fessor Riley, the United States Entomologist, has received speci- mens, and they prove to be the true Hessian fly. EntomotocicaL Notes,—In Siebold and Kalliker’s Zeitschrift, issued May 8th, A. Sommer has an elaborate and well illustrated article on the anatomy and histology of the large common Pod- uran, Macrotoma plumbea; the descriptions, however, do not ap- pear to be comparative.

Some Ciliata and Tardi- grada have been included, and these have, although not to the same degree, exhibited a remarkable tenacity of life. The inter- vals of sleep and vigorous life have also been brought into strict accord with the durations of dry and wet periods of the year, so that the subjects of the experiments have been kept in a perfectly dry condition during the whole of the long drought which characterized the past summer. Moreover, some older dried specimens were subjected to an ar- tificial process of desiccation. They were kept for a time in a hot- air chamber, the heat in which was raised to 2000 F., and subse- quently the miniature aquarium in which they were inclosed was plunged into a freezing mixture. Neither process kille@them nor greatly diminished their vital powers, their revivification in both ases being somewhat delayed. Certain poisons known to exert a baneful influence over higher animals were added to the water supplied to the rotifers, but in no way did they produce discomfort ; on the contrary, portions were taken into the stomach and partly digested. On the other hand,a drop of sewage water caused marked discomfort ; they immediately retracted their rotating or- gans and sank to the bottom of the cell. These were, so far as could be ascertained, poisoned, and this was probable owing to the free sulphide of hydrogen evolved by the putrescent sewage. From VOL. XIX.—NO. VII. 47 718 General Notes. [July, his observations the author is led to infer that rotifers will live and multiply on a very scanty supply of organic matter, provided only that the water is fairly well oxygenated. Attention is also called to the greatly diminished or no longer developed eye, due no doubt, to the withdrawal of the stimulus of light, the rotifers being nearly always kept in the dark.— Journal of the Microscopi- cal Soctety, February, 1885. sin THE MoxrHotocy OF THE CARPUS AND TARSUS OF VERTE- —As a result of embryological and literary studies I reach d following seed nad table for the carpus and tarsus: URODE (Menopoma, Cryptobranchas, PAIA Salamandrella, Ranodon PARIA Axolotl).

Echinoderms.—The stalked crinoids collected by the Challenger and reported upon by Dr, P. H. Carpenter, raise the total of ex- isting generic forms to six, with no less than thirty-two species. The bathymetrical range of the tribe is shown to extend from 100 fathoms to 2500. No less than 150 species of unstalked crinoids were collected by the same expedition. In the discussion of the pee a relations between the neocrinoids and the palæo- r. Carpenter is, upon certain points, at issue with Mr. Wachsmuth, the highest authority on the latter group. Of the species of Pentacrinus from West Indian seas, P. asterias, the /szs asterias of Linnzus, is the rarest, while P. decorus is far more plentiful than P. mulleri. Neither of these, nor P. blakei, have been met with elsewhere. Two species from the Western Pacific, one from the North Atlantic, on the European side, another from the tropical Atlantic, and a single mutilated type from the Japan sea, complete the known Pentacrini. There is, in fact, but little difference between this genus and Comatula, the chief distinction themselves by their dorsal cirri; while the stalked Pentacrini are not seldom detached by the fracture of their skins just below a nodal joint, and they then cling to any suitable attachment by means of the cirri of that joint, which bend downwards like the dorsal cirri of Comatula. The five-chambered organ at the base of the calyx is much smaller in Pentacrinus than in Comatula, but each node of the crinoidal axis presents a dilatation similar to the five in Comatula. In the Eastern Archipelago Pentacrinus is re- placed by the allied Metacrinus, eleven species of which were dredged by the Challenger. strictly homologous with the Malpighian tubes of Tracheata. M.

III. — The stage under examination is that represented on Figs. 12 and 13, 14 and 15 (Plates 111 and 1v) of my essay on the development of Limulus (Memoirs Boston Society Natural History, 1872). At this stage the oval blastodermic disc, with the six pairs of the cephalic appendages, is distinctly formed; the mouth is seen in a position in front of the first pair of appendages, and from it the primitive streak passes back to the posterior margin of the blas- todermic disc or “ventral plate.” The abdomen is separated from the head by a curved groove, as seen in Fig. 12 of my memoir. nature of the embryonic membrane, which I had previously re- garded as the homologue of the amnion, and afterwards as the serous membrane of insects, but which Mr. J. S. Kingsley’ has found to be secreted from the blastoderm. A thin section (Plate xxIv, Figs. 1 and 5) shows that the membrane is very thick, struc- tureless, the cellular appearance being confined to the external surface. This membrane is evidently secreted by the blastoderm ; the irregular cell-like markings (see my second memoir, 1880, Pl, i, Figs. 14, 144, 14¢, 14d) are, so to speak, casts of the blas- toderm , which with the marks of even their nuclei are im- __ pressed upon the membrane during the early stage in its forma- = Edited by Jonn A.

In my comparison of this membrane with the serous membrane, I certainly exaggerated its resemblance to the serosa of insects, as the latter is a much more delicate membrane, and with a charac- teristic appearance in Crustacea, the scorpion, myriopods and hexapods. The membrane in question appears to have its homo- logue, however, in the embryonic membrane of Apus, which we thus appears that this supposed point of resemblance in Limulus to the Tracheata is removed. A longitudinal section of the embryo of Limulus is represented by Fig. 2. The section passes through the blastodermic disc (ventral plate) and the indications of the appendages, on one side of the median line of the body. The epiblast entirely surrounds the yolk, forming a thin layer with nuclei, the cell walls not being distinct, while the nucleolus consists of a number of granules. The nuclei are two deep only on the cephalic portion. of the em- bryo. The blastodermic disc does not extend quite half way around the egg. The six pairs of appendages are well developed, increasing in size from the first to the last pair. The mesoblast is now well developed; the nuclei well marked, but the cellular walls more or less effaced. The mesoblastic arthromeres are now well indicated. The somatic cavities are well marked in each appendage ; the somatopleure is from one to three cells deep ; the splanchnopleure is formed usually of two layers of cells, and is more or less continuous at the ends of the somatic cavities with the somatopleure. The relations of these divisions of the meso- protoplasmic network connecting ose present formed a dorsal row ranged next to the thin epiblast over about one-quar- ter of the periphery of the ovum. earlier stage, however, 724 General Notes, [July, The abdomen has not yet undergone segmentation; the incip- ient steps are represented in Fig. 2, where there appear to be arising five mesoblastic segments (1, 2, 3, 4,5). Between the first and second mesoblastic mass is a narrow cavity which sends a branch forward to the base of the abdomen, and a second obliquely downward and inward ; at 2 and 3 in Fig. 2 there are narrow cavities or splits (somatic cavities ?) which communicate with a longitudinal internal opening, which extends in a direction parallel to the under (now outer) surface of the abdomen. In this respect the embryo of Limulus is very different from that of the scorpion and spiders (see especially Balfour’s Figs. 5, 6, Pl. xix, and Fig. 15, Pl. xx), where the abdominal segments, with their appendages and somatic cavities are formed contemporane- ously with those of the cephalothorax. The innermost meso- dermic cells are now arranged in long cords, destined to form the ventral adductor muscles of the abdomen. The mode of formation of the head and its shape at this time presents important differences from that of tracheate embryos. The procephalic lobes are not developed ; the preoral portions of e head, z. e., that part in front of the first pair of limbs is very small, short and narrow, merely forming the end of the oval blas- todermic disc, seen in my earlier published figures. The struc- ture of the preoral portion of the head (procephalum as we may term it), is seen in longitudinal section in Fig. 3, fc, to apparently consist merely of an extension of the postoral part of the head ; with apparently one or two splits in the mesoderm (mst, ms*), t nature of which I do not understand; undoubtedly farther sec- tions and comparisons will throw light upon it. The first nervous ganglion is seen at Fig. 5 to result (as also first shown by Kingsley) in an ingrowth of the epiblast (nv. c) ; carrying into the interior a mass of epiblastic nuclei, which envelop the myeloid substance (my), which, as in older embryos, remains unstained by the carmine. The mesoblastic nuclei stop at a large cell (c), beyond which are long incipient loose muscle-cells with a few scattered nuclei. d procephalum terminates abruptly, forming, as seen in our saia figures already referred to, the end of the blastodermic sc. The absence of the procephalic lobes in the embryo Limulus of this stage seems to us to be a very significant fact, and to point - commi ith eate os. At the same time the gen- : eral mode of formation of the blastodermic disc (ventral plate) of 1885.] Embryology. | 725 Limulus is much like that of the spider, as seen in the mode of origin of the mesoblastic segments and the probable origin of the hypoblastic cells. There is a superficial resemblance between the embryo of Limulus and of the spider, as may be seen by a com- parison of our Fig. 2 and Balfour’s Fig. 15. Without much doubt the Tracheata and Palzocarida, as well as Crustacea Neo- carida, branched off from a common ancestor, but the more im- portant morphological points show that the terrestrial, air-breath- ing tracheates were a much later branch of the arthropod tree than the marine branchiate Paleocarida and genuine Crustacea. Probably the Palzocarida (Limulus and other Merostomata, and Trilobita) were the earliest arthropods to appear; after them arose the Crustacea, perhaps at nearly the same time the Arachnida, and finally the Myriopoda and the winged insects. Without much doubt the earliest branchiate forms were our Protocyclus,' the ancestor of the Palzocarida; and a protonauplius form, the forerunner of the Crustacea; these were marine, perhaps branchi- ate organisms, with a few pairs of simple oar-like swimming appendages either around or just behind the mouth, and which were free-swimming or creeping forms; the Protocyclus was, perhaps, a solid oval creeping animal living at the bottom on mud or sand. The branchiz probably became first developed on the limbs of the free-swimming Protonauplii, as they needed, owing to their great rapidity of movement, the means of rapid aération | of the blood; while in the heavily molded less oxygen-consum- ing Protocyclus, the evolution of gills was somewhat postponed. The steps from Protocyclus to Agnostus was not a very long one. The oldest arthropods, notwithstanding the recent discovery of a Silurian scorpion, were trilobites. The following conclusions are drawn from a study of the stage of Limulus here figured. The fact that the embryo Limulus had at first no abdominal appendages (uropoda), whereas there are temporary ominal appendages in the tracheates, shows that Limulus in this impor- tant respect has little in common with the Arachnida, Myriopoda or Hexapoda. On the other hand in the embryo Crustacea the cephalic limbs are first indicated ; the nauplian limbs as we the zoéan appendages being cephalic ; the uropods not appearing until after the Crustacea leave the egg. These facts indicate that Limulus probably descended from a type in which there were cephalic appendages only, and no abdominal appendages. The absence of a serous membrane, of an amnion, and of procephalic lobes, of temporary embryonic abdominal appendages (at the stage above described) ; also of protozonites (seen in the early embryo of the scorpion and spider) tend to prove that the embryo of Limulus has little in common with that of Tracheata. 1 See Development of Limulus, 1872, p. 726 General Notes. [July, On the other hand the earlier stages in the embryology of Limulus resemble those of Crustacea in the absence of the pro- cephalic lobes; in the primitive development of cephalic appen- dages alone; the comparatively early appearance of the branchiæ of Limulus in the stage succeeding that figured in this essay, shows that the Limulus enn never had any genetic connec- tion with a tracheate arthro On the other hand, the pina features of mesoblastic somites are also seen in the worms, in Peripatus and in Annelida. It appears that the embryology of Limulus is scarcely more like that of tracheates than. Crustacea ; it is a very primitive type standing nearer the branchiate arthropods than the tracheate, but on the whole should be regarded as a generalized or a composite form, which with its fossil allies, the Eurypterida and Trilobita, form a class by themselves with a superficial resemblance to the Arachnida. It seems to us that the above-mentioned characters, which sep- arate the early embryo of Limulus from the tracheates, are as important, if not much more so, than those of the absence at first of an archenteric cavity or differences in the mode of origin of the mesoblast, noted by Mr. Kingsley in his brief paper on the development of Limulus. In these general, primitive embryonic characters Limulus appears to be as nearly allied to the annelids as to the tracheates; and too much dependence should not, it seems to us, = placed upon them in ae to establish the true relations of the Paleocarida among the arthropods. In the higher worms the two longitudinal mesoblastic bands split into somatic and splanchnic layers (K y). In Mysis Metsch- nikoff states that the mesoblast becomes broken up into distinct somites (Balfour's Embryology, 1, 436). If so, then this charac- ter is not one of much importance to separate Limulus from the Crustacea. The ultimate origin of Limulus from the same stock as that which gave rise to the modern annelids seems not im- probable. EXPLANATION OF PLATE XXIV.

THE “ ZOOPHILIST.”—The believers in physiologi- cal experiment upon animals as a means for increasing our know- ledge of the body will all heartily indorse Professor Martin in his vigorous “ castigation” of the truth-distorting and fanatic Zobphilist, an English sheet whose ostensible object is the preven- tion of cruelty toward animals, People who are opposed to what is popularly known as “vivisection,” may be divided into two classes, the reasonable and the unreasonable. It is the duty of physiologists to maintain the respect of the former class by the presentation of the abundant arguments which defend the use of the lower animals, under proper conditions, for scientific pur- poses, The latter class could probably never be completely silenced except by a course of unresponsive contempt, but for all that one must occasionally be pleased. to see a fool get his just deserts. CONDITIONS MODIFYING THE DIASTATIC ACTION OF SALIVA— Messrs. Chittenden and Smith have extended the valuable re- searches of the former upon the diastati¢ action of saliva. The following are their conclusions; “1, The diastatic action of saliva can be taken as a definite measure of the amount of ferment present only when the dilution of the saliva in the digestive mixture is as 1:50 or 100. The limit of dilution at which decisive diastatic action will manifest itself with formation of reducing bodies is I : 2000-3000, under the conditions previously given. 2. The diastatic action of neu- 1:50 or 100, and is apparently out of all proportion to the amount of alkalinity. 3. Sodium carbonate retards the diastatic 728 General Notes, [July, the proteid matter, and also to a direct stimulation of the ferment. Likewise peptone tends to diminish in a similar manner the retarding action of the various percentages of sodium carbonate. To accomplish this, however, the amount of peptone must be. proportionate to the percentage of alkaline carbonate. 7. Pep- tone tends to prevent the destructive action of dilute sodium car- bonate on salivary ptyalin, thus giving proof of the probable formation of an alkaline-proteid body. 8. Saliva with its proteid matter saturated with acid appears to have a greater diastatic action than when simply neutralized ; except when the acid pro- teids thus formed are above a certain percentage. Small percent- ages of peptone saturated with acid similarly increase the dias- tatic action of neutralized saliva up to a certain point. Increasing the percentage of acid-proteids finally causes a diminution of dias- tatic activity. 9. The retarding influence of acid-proteids is out of all proportion to their power of destruction. Large percent- _ ages, however, of acid-proteids may cause almost complete de- struction of the ferment. 10, The most favorable condition for the diastatic action of ptyalin, under most circumstances, appears to be a neutral condition of the fluid together with the presence of more or less proteid matter. The addition of very small amounts of hydrochloric acid, however, to di/ute solutions of saliva, giving thereby a small percentage of acid-proteids, appears to still further increase diastatic action. Under such conditions a minute trace of free acid appears to still further increase the action. 11. 0.003 per cent free hydrochloric acid almost com- pletely stops the amylolytic action of ptyalin. The larger the amount of the saturated proteids the more pronounced becomes the retarding action of free acids. 12. The retarding action of the smaller percentages of free acid are not due wholly to destruc- tion of the ferment. Pronounced destruction takes place with 0.005—-0.010 per cent free hydrochloric acid. 13. Proteid matter, 885. PaystoLocy OF THE SYMPATHETIC NERVES.—The generalization — of Dr. Gaskell “ On the relationship between the structure and the nction of the nerves which innervate the visceral and vascular systems ” are of the highest interest and importance. Dr. Gas- kell calls attention to the fact that involuntary muscles, visceral =~ and vascular as well as cardiac muscle, are supplied by two kinds _ of nerve fibers which are histologically distinct, the medullated y 1885.] Anthropology, 729 or white and the non-medullated or gray nerve fibers. Contrac- tion of involuntary muscle is brought about exclusively by im- pulses proceeding along the non-medullated nerves, while relaxa- tion or inhibition of muscular contraction is as invariably produced by impulses conducted by the medullated nerves. All nerves in their course from the spinal cord to the sympathetic ganglia are of the medullated variety, but on leaving the sympathetic ganglia they are separable into two groups of medullated and non-me dul- lated fibers; the medullated sympathetic fibers are, Soe easily distinguished from those of ordinary striated muscle by their smaller diameter. Dr. Gaskell writes: “In previous communications I have shown that the heart of various cold blooded animals, e. g., frog, ' tortoise, crocodile, is innervated by nerves coming from two dis- tinct scurces in the same way as the heart of the warm-blooded animal; and I am now enabled to make the further communica- tion that in the dog, cat, rabbit, tortoise and crocodile these two sets of nerve fibers are structurally differentiated from each other in precisely the same manner. The vagus fibers from their origin up to their entrance into the heart are medullated, the sympa- thetic fibers in the whole of their course from the basal ganglia of the Aap ale ie along we annulus of Vieussens to the heart are non-medullated. very involuntary muscle is inner- vated by rotor nerves which are histologically and physiologically distinct; the one gray, non-medullated, causing contraction of the muscle; the other white, fine, medullated, causing relaxation of the muscle.’ '— Jl. of Physiology, Vol. vi, p. tv.

In the first place, since those devoting themselves to any branch of science belong to one brotherhood, the introduction of the word German is unfortunate. In drawing up any code of craniometric measurements the researches of Broca must be the basis, Professor Garson advocates the con- dylo-alveolar plane. The audito-orbital plane is in some instances directed more or less obliquely downward; it is more difficult to place the skull in the latter plane; the apparatus of suspension is complicated and in the way of important measuring. Again, the horizontal measures are not important, the form of the skull is quite as fully indicated by measurements from fixed points by the sliding callipers.

Mayer’s Carsotic Acip SHELLAC.—Finding that ee oil and creosote produce fine granulations when used in ordinary shellac method, Dr. Paul Mayer has adopted a new pirer of dissolving the shellac, by which an excellent fixative is ob- tained that never shows any traces of Lepere The fixative is applied by a fine brush to the cold sl Mayer prepares the solution in the following manner : 1. Dissolve one part of bleached shellac in five parts of abso- lute alcohol. 2. Filter the solution and evaporate the alcohol on a water- bath. A yellowish residue quite stiff when cold is thus obtained. If any cloudiness arises during evaporation, the solution must be filtered again. 3 Dissolve the shellac residue in pure carbolic acid on a water- bath. A concentrated solution of carbolic acid is obtained by exposing the crystals to the air until they dissolve, or by adding a small amount of water (about five per cent). uantity of acid should be sufficient to give a thickish liquid when cold. This fixative is painted on to the cold slide with a brush, at the time of using. The sections are then placed, and the slide left in the oven of a water-bath for some minutes (10-15 minutes I find sufficient). The carbolic acid is thus evaporated, leaving a perfectly transparent stratum of shellac on the slide. The sec- tions are next ae from paraffine in the ordinary way and mounted in balsa This method is considered to be the best and simplest for fix- ing stained section The shellac can te dissolved directly in carbolic acid, but then the fluid must stand a long time in order .to become clear, as it cannot be filtered. For this.reason it is preferable to dissolve first in alcohol. Note.—According to a note just received, Mayer now prepares the shellac as rae ellac is slice and heated with crystals of colorless carbolic acid until it iaeiei In filtering the funnel should be heated over a flame. It will filter slowly but quite i If it is too thick crystals of carbolic acid may be added until the desired consistency is reached.

[July, Following the principle of the Lewes and the Ray’ instruments, the ether spray is thrown on the under side of the object-plate instead of on the object itself. The apparatus consists of a short cylinder (Fig. 1 A), closed by the plate, P, on which the object is placed for freezing. A metallic tube (4) drawn to a fine point penetrates the base of the cylinder, and another (4) its side. The vertical tube (æ) is con- nected by rubber tubing with a small bellows, while the horizon- tal tube (4) is similarly connected with a glass tube which passes through the stopper of a bottle containing ether, reaching nearly to the bottom. When the bellows is set in motion the current of LULL 2 TTT i | nA | | | g | 2 4 | | | — | | ii -n | DDD c a Fic. 1.—Freezing cylinder seen in section. air throws the ether spray against the plate, P, and the rapid evaporation thus produced soon lowers the temperature suffi- excess of condensed ether.

BY MARIANO DE LA BARCENA, N the month of January, 1884, some excavations were being made, by means of dynamite, at the foot of the small hill known as “ Peñon de los Baños,’ some four kilometers east of the City of Mexico. The excavations were made with the object of quarrying building stone for the Military Shooting School which is being constructed near the Pefion and under the supervision of Colonel Don Adolfo Obregon. This gentleman, at the beginning of January, was informed that among the rocks loosened by the dynamite some bones were to be found, and he accordingly col- lected and delivered them to the Minister of Public Works, Don Carlos Pacheco, who appointed the writer to make a study of them. The preliminary examination being made, I presented them to the Mexican Society of Natural History, giving at the same time public notice of so important a discovery. Some days afterwards I explored the formation in which the bones were found, continuing my studies with the coöperation of Don Antonio del Castillo, professor of geology, whom I invited to take part in my investigations ; both making upa n which has lately been published in Mexico. The human remains are firmly imbedded in a rock formed of silicified calcareous tufa, very hard and of a brownish-gray color. The cranium with the lower and upper maxille and fragments of the collar-bone, vertebrz, ribs and bones from the upper and lower limbs are exposed. The bones lie in disorder, proving that the rock in which the ongoing was found suffered an up- VOL, XIX.—NO. VIII. 740 Notice of some Human Remains ` (August, heaval before consolidation, a circumstance which an examination of the ground further verifies. The bones present a yellowish appearance and the characteristic aspects of fossilization, it being noteworthy that they are not coated with layers of the calcareous rock as is observed in the recent deposits, but are firmly imbed- ded in the stone, which also fills the cells of the tissue. Several distinct formations and rocks are seen in the locality where the bones were found; towards the center rises the small hill “ del Peñon,” consisting of volcanic porphyries; on the base to the north there appear first a clearly recent formation made up of vegetable earth, marl and ceramical remains, which in the upper part are modern, and in the lower belong to the Aztec ceramics. Under this recent formation are the calcareous layers in which the human remains were found. These layers crop out with a rise toward the northern bound- ary, forming the end of an esplanade which surrounds the hill, and is three meters above the actual level of the waters of Lake Tez- coco. The layer of hardened rock does not extend with regu- larity the whole distance from the before-mentioned edge to the foot of the hill, some intervening spaces occurring in which this rock does not appear; the resulting hollows being filled with recent ground. This circumstance as well as the appearance of the layers of calcareous tufa, prove that this rock was upheaved after the deposit of the human bones, by the igneous rocks which crop out in the neighborhood of the hill forming dykes. This upheaval is also verified by the numerous smalls veins which are found in different directions on the ground. In order to clearly establish the age which the deposit of the human bones might have, the best scientific method would be to find some animal fossil remains in the same formation which would distinctly mark the age of the layers of that calcareous rock, but until now, notwithstanding the many searches made, it has not yet been possible to find any traces of extinct animals; _ neither has there been found any vestige of ceramics or other re- mains that might indicate that these rocks were clearly modern, as among them the only things found were the human bones, roots converted into menilite and some small indeterminable lacustrine shells formed by the same calcareous substance. These shells L . belong to genera which have lived in Quaternary as well as ins eee : a sa waters, it ae: been Sos to determine their species 1885.] Sound near the City of Mexico. 741 on account of the bad state of preservation in which they were ound, In the region to the south of the hill more modern calcareous rocks are seen, and thicker deposits of recent ground with remains of Aztec ceramics. Not being therefore able to utilize the palzontological data for determining the age of these calcareous layers, we must fall back on the inspection of the ground. Two facts seem at once to reveal that even supposing the forma- tion to belong to the present age, it must be of remote antiquity. These facts are: The elevation of the ground above the actual level of the Lake of Tezcoco, and the remarkable hardness of the rock in which the bones are found, different from the other calcareous rocks that contain remains of ceramics or roots® of plants clearly modern. The upheaval of the lacustrine layers which contain the human remains might have taken place through the diminution and retirement of the waters of the lake, or by the upheaval of volcanic rocks. In the first case it could have been occasioned either by a vio- lent filtration of the water, or a slow evaporation ; but nowhere in the valley of Mexico are any traces to be found of a crack or opening through which the waters could have escaped, and which ought to appear outside of the present level of the lake, as if it were below, all the water would have disappeared. If the lower- ing of level was due to evaporation, a theory which would be more admissible, because from the time of the conquest of Mex- — ico to the present the submerged surfaces have notably dimin- ished, the time necessary to have elapsed in order that the level of the lake might fall three meters to its present one, must have been very long. What is most probable is, that the upheaval is due to volcanic action; for although until now no basalt has been discovered immediately underneath the place occupied by the hardened layers, yet dikes of that rock are to be seen in different directions at the foot of the hill, and even the volcanic masses which constitute it are found upheaved and inclined, demonstrat- ing the succession of geological phenomena in that vicinity. Let us now trace the origin of the silicified calcareous rock in which the bones were found, and which is different from the majority of the lacustrine rocks which occupy the valley of Mexico, these latter being, for the most part, thick and extensive i 742 Notice of some Human Remains [August, layers of pumice, tufas, marls, volcanic ashes, clays and allu- vions. In order. to proceed with more certainty in this investigation, I compared the calcareous rock in question with those which resem- bled it most from other parts of Mexico, and found it could only be considered similar to those which are clearly of a hydnotaces mal origin. The hot-water spring which exists in the eastern part of the hill del Peñon- forms sediments somewhat similar to the silici- fied calcareous tufa; but these are on a small scale and their formation is so slow as to preclude the belief that this spring could have filled all the immediate surroundings of the hill with deposits of such magnitude. What is most probable is, that in remote times there were great emissions of mineral thermal waters through different fissures, and in several directions, whose appearance was simultaneous with the basaltic masses that form dikes at the foot of the hill, as in the faces of the rocks sedimen- tations similar to the referred ones are perceived, there being furthermore many small veins which cut through the basaltic masses and even the calcareous rock. By this it is seen that a series of volcanic phenomena must have taken place in that spot, beginning before the human remains were deposited, and which further continued when the material which received them was but little consolidated. _ The succession of these phenomena took place, without doubt, in the following Way: Ist. Emission. of thermal waters and appearance of basaltic rocks, upheaving the massés that formed the hill. These waters mixed with those of the lake which surrounded the hill and ex- tended over a large area of the valley of Mexico; the calcareous deposits gradually accumulated around the hill, and being still . soft the human corpse was deposited upon them. - 2d. When the bones were already imbedded in the lacustrine deposit there came a new volcanic upheaval which raised this deposit, as the higher level which it now occupies proves, and the disorder in which the bones of the skeleton appear.

Tezcoco, isolated deposits of this, silicified calcareous rock are seen, showing that the volcanic upheaval extended over a large surface, and that the thermal waters appeared several times. One of these deposits is to be found at the height of two meters above the present ground among rocks of the hill de? Tepeyac, north of the City ot Mexico. The geological circumstances of the event once determined, and notwithstanding that the paleontological data are wanting that might mark with precision the relative age of that deposit, it is to be believed that it must be of remote antiquity, consider- ing the circumstances which the mentioned rocks present, as well as the geological phenomena which have there taken place and of which no notice is given in the hieroglyphics or traditions of the ancient Mexicans. This consideration alone is enough to believe that the man of the Peñon is prehistoric The odontological characteristics indi- cate that this man belonged to an unmixed race, the teeth being set with regularity and corresponding perfectly the upper with the lower. They present the peculiarity besides, that the canine. teeth are not conical, but have the same shape as the incisors; a peculiarity which has been observed in other teeth found in very ancient graves of the Toltecs. The size and shape of the bones of the limbs are those corre- sponding to a man of ordinary stature, and from the appearance of the teeth the man must have been about forty years old. The greater part of the cranium having been destroyed, it was not possible to determine its diameters and thus classify it. The stratigraphical and lithological characteristics of the ground seem to indicate that the formation belongs to the upper Quaternary or at least to the base of the present geological age. It may as well be remarked that at the foot of the steep slope of the Tepeyac hill, near the place where the calcareous sedi- ments are to be seen among the rocks of the hill, as was pre- viously mentioned, some excavations were made, and Professor Don Antonio del Castillo found various bones of ‘Quaternary animals enveloped in a calcareous rock similar to that of the Pefion. The distance between this hill and the Tepeyac is nearly three miles. The excavations continue at the foot of the hill del Peñon, with 744 Human Remains found near the City of Mexico, (August the object of quarrying building stone, and this will allow in the course of time some other data to be discovered which will clearly mark the geological age of the event; a tooth of a mas- todon or an object of the present age would at once be the land- mark assigning it a fixed page in the history of the earth. The authenticity of the fossil is not only determined by the report of Sefior Obregon and the identity of the rock which contains the remains with the blocks that are being at present quarried at the foot of the hill, but I, myself, have determined this authenticity, having found part of the human remains still imbedded in the ground rock. ; I will conclude by mentioning other facts that indicate the an- tiquity of man in the valley of Mexico. Twelve years ago, in executing some works for the drainage of the valley, in the direc- tion of Tequisquiac, numerous deposits were discovered belong- ing to Quaternary animals, such as elephants, mastodons, glypto- dons, etc., and among one of these deposits a fossil bone was found carved by human hand and imitating an animal’s head. Unfortunately no care was taken to determine if it was found simultaneously with the bones of the Quaternary animals. The appearance of the carved bone and of the cuts and incisions which it has, denote a remarkable antiquity, and it has character- istics of fossilization. Two years ago I discovered some remains of ancient ceramics in the pumice tufa which is under the basaltic lava formation found in the south-eastern part of the valley of Mexico; the lava occupies a large area, and in some points its thickness i is over two meters. No tradition makes any mention of this volcanic cataclysm before the existence of man in the valley of Mexico. These are, at present, all the data I can give relative to the man del Peñon. - On my return to Mexico I will continue with a further investigation of the ground where the discovery was made, and will communicate anything new that may be found, in order to determine the sar kee importance which these uman remains may have. s 1885. | © Evolution in the Vegetable Kingdom. 745 EVOLUTION IN THE VEGETABLE KINGDOM. BY LESTER F. WARD, A.M. (Continued from p. 644, Fuly number.) II. GEOLOGICAL VIEW. ` The most ancient fossil remains that have been referred to the vegetable kingdom are two species of Oldhamia from the Cam- brian deposits of Ireland, but the vegetable character of these forms has been latterly called in question. From the Lower Silurian forty-four species, chiefly marine alge, have been named. Among these, however, are included the earliest terrestrial forms. Not to mention the problematical Aupterts morieret of Saporta, we have Sphenophyllum primevum Lx., and two other vascular plants from the Cincinnati group. In the Upper Silurian thirteen spe- cies are recorded, five of which are vascular plants. One of these is Cordaites robbit Dawson, found in the Silurian of Hérault as well as in the Devonian of Canada. The Devonian furnishes 188 species of fossil plants, while from the Permo-Carboniferous nearly two thousand species are known, or nearly nine-tenths of the entire Palzeozoic flora. With the Mesozoic a great diminution appears in the abundance of vegetable life that has been preserved. Only sixty-seven spe- cies have been found in the whole of the Trias. With the Rhetic a new impulse is felt increasing through the Lias and reaching a second but much reduced maximum in the Oodlite, from which 419 species are recorded. The wave then again recedes until the close of the Gault is reached. The Cenomanian of Europe, with the beds of Atane in Green- land and the Dakota group of the United States which probably correspond to it, mark a new epoch, supplying together nearly five hundred species of fossil plants. That member of the Cretaceous formation which immediately overlies the Cenomanian, viz., the Turonian, to which the Fort Benton group of American rocks seems to belong, is almost destitute in both countries of vegeta- ble remains, but with the Senonian we meet again the increasing voiume which was merely interrupted by unfavorable conditions for the preservation of plants. Here we have in European strata, in Patoot, Greenland, and in British Columbia 354 species. Al- though none have yet been described from this horizon within the territory of the United States, I have myself demonstrated 746 Evolution in the Vegetable Kingdom. [August, their existence to a limited extent, and live in hopes of yet bring- ing to light an important Upper Cretaceous flora. We are thus brought to the Laramie group of the Western Territories, which, though a brackish water deposit and difficult to correlate with other deposits, may be regarded as extreme Upper Cretaceous; 333 species have been thus far described from this group, which presents a flora of a still more Tertiary aspect than that of the Senonian proper, and fittingly ushers in the Ter- tiary flora. From the Paleocene of Sézanne and Gelinden to the Miocene the progress is uniform and rapid. The Eocene of the old world (Paris basin, Aix in Provence, Monte Bolca, Monte Promina, Monte Pastello, Isle of Wight, London clay, etc.) furnishes over 650 species, while the Green River group of America, including the rich beds of Florissant, Colorado, probably of that age, has yielded more than two hundred. This is exclusive of the so- called Oligocene of the continent (Hering in Tyrol, Sotzka in Carniola, the Marseilles basin, Armissan near Narbonne, etc.) from which nearly 800 more have been taken. We thus have over 1800 pre-Miocene Tertiary plants, which is, however, much less than half of the Tertiary flora. The Miocene supplies nearly all the rest, yielding alone over 3000 species. It may be, as has been charged, that this number is too great, and that a portion of these plants belong to lower horizons. While Heer’s determinations in Switzerland have not been seriously questioned, his work on the arctic floras is doubtless open to revision, but this will not diminish the number of Tertiary plants, which, if we add to those already mentioned some 150 Pliocene species, will form an aggregate of nearly 5000. The Tertiary virtually closes the series for vegetable remains, the Quaternary having thus far furnished less than one hundred species of fossil plants. The development of plant life through the successive geologic ages may be graphically represented, so far as indicated by actual discovery, by the accompanying diagram or figure, in which the number of accredited species is taken as a measure of predom- 7 ve —_— and the- space assigned to each horizon in the vertical . a ale sents its duration in so far as the thickness of the es cnet time. 1885.] Evolution in the Vegetable Kingdom.

The fact is thus brought clearly to view that there have existed 748 Evolution in the Vegetable Kingdom. ` (August; two favorable periods for the preservation of vegetable remains —the Carboniferous and the Miocene—the wide interval between which is relieved by two less favorable periods culminating in the Oolite and the Cenomanian respectively. To what extent the in- tervals of great scarcity may yet be filled, it is impossible to pre- dict, but it is well to remember that it is only quite recently that the Oolite has assumed prominence as a vegetable deposit, and this chiefly through researches made in India and Siberia. With the further development of such outlying regions it is to be hoped that a much greater degree of uniformity in the different geological periods will be secured. But of this there is no cer- tainty, and it is perhaps equally probable that future research may _ tend to exaggerate the present extremes. Three things must combine for the successful development of a fossil flora in any given geological formation: 1. The requi- site vegetation must have flourished at the period in question; 2. the conditions for its preservation and subsequent exposure must have existed ; and 3. the localities in which it is imbedded must be found and worked. As regards the first of these conditions, we know that great fluctuations of the land surface of the globe have taken place, and periods may have been passed during which these were much less in amount than at others. Still, there can be little doubt that the variety at least, if not the abun- - dance of vegetation, has undergone a. somewhat uninterrupted increase since the earliest times. The second condition is a much more serious one. Immense periods may have elapsed without . any record being made, not because vegetation was scarce, nor because land areas were limited, but because, as seems now to be the case over most of the globe, all vegetation was allowed to decay and return to the atmosphere. Again, vast beds may have been deposited but never afterward raised up and exposed, and may remain forever inaccessible. It is only the third condition __ which it is within the power of man to influence. But when we consider the accidental manner in which a great part of such dis- _coveries have been made thus far, we may well presume that the most precious scientific treasures which the earth holds may remain undiscovered indefinitely although within the easy reach of the investigator, 5: eo : III. Boranicar View. ~ Most of the plants of the Paleozoic age belong to archaic _ types long since extinct and having only very much modified 1885. ] Evolution in the Vegetable Kingdom. 749 living representatives. This is less marked in the ferns than in those forms which have as their nearest modern descendants the Equisetacez, the Lycopodiacee and the Conifere. The Palzo- zoic ancestors of the Equisetaceze are the Calamariz, having the genus Calamites for their typical form. Those of the Lycopo- diaceze are the Lepidophytes with Lepidodendron as their type; while according to the most recent researches the Conifere had as their ancestral form the Cordaitez, long classed among the Cycadacez, with Cordaites as the principal genus. As a means of expressing the fact of this prolongation of living forms through the geologic periods ahd of denoting the probable descent of modern from these archaic types of vegetation, the terms Filicineze, Equisetinee and Lycopodinee have been em- ployed as broader than the corresponding ordinal designations in common use. The Marquis Saporta has sought to accomplish the same object for the Coniferze by the term Aciculariz, but this unfamiliar substitute will not be likely to meet with general acceptance. The cellular cryptogams, which, admitting Oldhamia to be a plant, had two representatives in the Cambrian, constituted the principal vegetation throughout the Silurian. Yet the ferns, if we accept Saporta’s Eopteris, the Equisetineze and Lycopodinee, all had their origin in the Lower Silurian, while the Conifere, through Cordaites, made their appearance in the Upper Silurian. Three species of Rhizocarpez (Sporangites, Protosalvinia) have been described by Sir J. W. Dawson from spore-cases detected in Devonian rocks of both Canada and Brazil. Heer had already* mentioned, in 1874, what he regarded as the fruit of some rhizo- carp from the Lower Carboniferous of Spitzbergen, and there can be little doubt that many of the spore-bearing plants of the coal measures belonged to this order, although none have been de- scribed from the Carboniferous proper. This little group, which has been supposed in a manner to mark the transition from the cryptogams to the gymnosperms, reappears, according to Heer, in the Odlite of Siberia, the Urgonian of Kome and the Ceno- -manian of Atane, Greenland. It occurs in our Laramie and Green River groups, in the Oligocene of France, and in the Mio- cene of Switzerland and Central Europe. With the true Carboniferous two new types appear—the Cyca- daceæ and the monocotyledons. If, with Grand’Eury, we rele- 750: Evolution in the Vegetable Kingdom. [August, gate the Medullosz to the ferns, the former of these types has a meager representation, but Renault admits Cycadoxylon in that formation, and Cyclocladia ornata occurs at Saarbrücken, while Schenk finds a true Pterophyllum in the coal flora of China. The presence of monocotyledons in the Carboniferous was long disputed, based as it was upon certain palm-like trunks de- scribed by Corda from Radnitz. But we now have one species of Palzospathe whose monocotyledonous character has not been questioned. The problematical sporangium, too, formerly sup- posed to occur no lower than the Permian, has now been found in the Carboniferous of St. Etienne, of Wettin, of Mazon creek, Illinois, and of Pittston, Pennsylvania, while so skeptical an author as Nathorst, in one’ of his latest works, defends its claims to be called a monocotyledon. Thus we find that all the leading groups or types of vegetation, except the dicotyledons, had made their appearance at the close of the Carboniferous age. Before passing to that important sub- class of the vegetable kingdom, the Ligulate and the Gnetacee, though numerically unimportant, deserve notice because they have been regarded by some as transition forms connecting the great types. The Ligulate are allied to the Lycopodiacez, and the genus Selaginella has sometimes been placed in the one and sometimes in the other of these orders. It is claimed to have been found in the Carboniferous, but of this there is doubt. Its first certain appearance is in the Cenomanian beds of Atane, Greenland, but ‘it also occurs in our Laramie group at Golden, Colorado, and at Point of Rocks station in Wyoming Territory, The more typi- cal ligulate genus, Isoetes, makes its first appearance in our Eo- cene at Florissant, Colorado, and is Bic eee by two Miocene species in Europe. As regards the Gnetacez, by far the most ancient known rep- resentative is Heers Ephedrites antiquus, from the Odlite of _ Siberia. Only two other fossil species of this order are known, : ~n ers (Ephedrites) sotzkiana (which not only occurs in the o, zocene of Sotzka, but in several of the principal Miocene beds . oe of Switzerland, fria wd me = Ephedra johniana from leone rst ance of all other forms of plant life from that of the didoryledons 1885.]} Evolution in the Vegetable Kingdom. 751 is one of the most striking facts revealed by paleontology. Heer’s Populus primeva, from the Urgonian of Pattorfik, Green- land, described ten years ago, still remains the sole representative of this sub-class in any formation below the Cenomanian and the most ancient dicotyledon known.’ Not less remarkable, however, has been the march of these plants since their earlfest manifesta- tion, as will presently be shown. Having thus noted the time of first appearance of each princi- pal type of vegetation, we may now hastily glance at the mode oi subsequent development of each. This might be done from two distinct points of view, the absolute and the relative, but as the former would be powerfully affected by the defects in the geolog- ical record, no attempt will be here made to represent it graphi- cally. The relative point of view, however, admits of such rep- resentation which in a’ certain respect eliminates these defects. Collectors of fossil plants do not seek specially for particular types. They take all they find, and hence if the chances of preservation are equal for all types the chances of finding plants of a particular type would depend upon its abundance in the flora of the epoch to be studied, while conversely, the degree to which any type of plants is represented in collections would be a fair measure of its abundance in the flora of the given epoch. The accompanying diagram is based upon this assump- tion, and clearly shows the progress of each of the leading pes. The facts sustain in a striking manner the early generalization of Brongniart, against which Dr. Lindley so strongly inveighed as late as 1836, that there has been a general upward tendency in structural development through the geological periods. The Silurian was the age of cellular cryptogams, consisting principally of marine Alge. The reign of the vascular cryptogams began with the Devonian and closed with the Permian, the ferns con- stantly taking the lead but being strongly supported by the Cala- mariz and Lepidophytes throughout the Carboniferous. The gymnosperms assumed supremacy in the Trias; the Cycada- * Fossil wood supposed to possess the dicotyledonous structure has several times been found in lower formations (see J. G. Kurr’s “ Beiträge zur fossilen Flora der Jura-formation Wiirttemberg,” Stuttgart, 1845, page 9; Sorby “ On the occurrence of non-gymnospermous exogenous wood in the Lias near Bristol,” Microsc. Soc, — Ill, 1852, pp. 91-92), but evidence of this class is not yet accepted as con- clusive. 752 Evolution in the Vegetable Kingdom.

Of the present flora they form less than sixty per cent, and doubtless their relative position in the fossil flora is exaggerated, owing to the failure of the myriad fungoid forms, existing then as now, to leave any traces in the rocks. The systematic value of the prevailing subdivision of the dicotyledons into monochlamydeous and dichlamydeous, and the latter again into polypetalous and gamopetalous, diminishes with the progress of research. The first of these divisions is invali- dated by the fact that the natural affinities are between apetalous and polypetalous and not between apetalous and gamopetalous plants, the last named division being the highest in point of struc- tural development. The apetalous division forms forty-five per cent of the dicotyledons in the Cenomanian, thirty-seven per cent in the Miocene and only fourteen per cent in the living flora. The polypetalz are fifty per cent in the Cenomanian, forty-eight per cent in the Miocene and forty per cent in the living flora. The Gamopetalz are five per cent in the Cenomanian, fifteen per cent in the Miocene and forty-six per cent in the living flora. Making all due allowance for the fact that the Gamopetalz of the living flora are more largely herbaceous than either of the other divisions, which fact, properly viewed, constitutes a strong proof of their greater recency, this evidence would seem quite sufficient to establish the order of development of the dicotyledons as here arranged. As still further confirming the general law of development in vegetable life, we observe the great decline of the cryptogamic types that predominated throughout the Palæozoic. The same is true to a less extent of the gymnosperms, and notably of the Cycadaceæ. The monocotyledons have also probably declined, as have the lower or monochlamydeous dicotyledons. The only one of all the leading forms of life of which we can positively say that it still preserves an upward tendency is the gamopetalous division of the dicotyledons, which, unless arrested by human agency, seems destined to form the dominant type of vegetation or the next geologic epoch. 754 The Relations of Mind and Matter. [August, THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. (Continued from p. 691, Fuly number.) IIL. DEVELOPMENT OF THE NERVOUS FUNCTION. N the last section the mechanism of the ‘nervous system was considered. The modes and causes of its special development, and particularly the influences controlling the evolution of the cerebrum, now call for consideration. As already said, conscious- ness may, for all we know to the contrary, attend every nervous manifestation. But consciousness in that clearly defined and centralized condition which we call the psychical is the outcome ` of a long era of development through which the nervous mech- anism has attained a high degree of specialization. At first ex- cessively vague and faint it gradually grows stronger and more definite, until it reaches its ultimate in the vigorous, clearly de- fined and highly developed consciousness of man. This result has been in great part an outgrowth of the growing sensitiveness of animal life to external energy. In the lowest forms this sensitiveness is undoubtedly very slight. In the Pro- tozoa it is probable that touch is the only sense that has any degree of strength, though it seems evident that these animals are somewhat affected by influences emanating from substances at minute distances. Whether the vague sensations which attract the Protozoa to their food arise from physical emanations of the nature of smell, or from some heat or light influence, cannot well be determined. In many of the lower Metazoa there is no indi- cation of any superior sensory powers. In sessile forms, indeed, the powers may be yet lower. The sponge, for instance, may possess only the sense of touch, resident mainly in its cilia. The fixed polyps may possess no higher sensitiveness, though in the free forms, such as the Medusz, there is an evident display of more varied and delicate sensitiveness. Yet in all the lower forms of animal life one thing is evident. External energy does not force its way into the body in any very _ great quantity, and it is quite possible that every sensation may _ call forth a motor response. This, indeed, seems to be the case in yet higher forms of life. The sensations are so limited in number that there can readily be a motor response to every sen- _ sation, and there is no reason why there should be a change from 1885.] The Relations of Mind and Matter. 755 the primitive system of direct and immediate communication be- tween the organs of sensation and the organs of motion. If in these forms intermediate ganglia exist, their sole duty may be that of a division of the current of energy and the drafting it off to the proper muscles, As we ascend to higher forms of animal life, however, a more developed sensitiveness appears. This is a necessary result of animal development. Higher life conditions require superior powers of perceiving prey or enemies, and greater quickness in pursuit or flight. For this, sensitiveness to more and more dis- tant impressions, to more delicate conditions of energy, and to a greater variety of emanations becomes requisite. The originally general sensitiveness must become specialized, and the nerves attain varied endings suitable to the reception of diversified modes of vibration or contact. This absolutely necessary consequence of the development of animal form yields another consequence of considerable import- ance. If the sensory organism becomes highly developed and capable of receiving delicate impressions both from near and far, the inflow of energy must become so great and continuous that a motor response to every sensation will become impossible. There must be some means of checking the inflowing current and preventing the whole of it from reaching the muscles, or the body will wear itself out from the very superiority of its organization. If the sensory currents be permitted to reach the muscle fibers these cannot but respond, and would thus be steadily in the con- dition of fatigue and incapability. It necessarily follows that a full development of nervous susceptibility is impossible unless in some method the excessively numerous external energies which beat upon the body can be prevented from bringing all their force to bear upon the muscles. This is the secondary phase in the development of the nervous function, and nature has chosen two methods of attaining the requisite end. In the one case, as the nervous substance grows more susceptible its sensitive terminations are covered by an in- durated material, through which energy cannot readily force its way. The special organs needed to receive the more delicate forms of energy are developed only on limited tracts of the body, and touch and temperature alone are capable of affecting the whole surface. With the great mass of animals the effects of* VOL, XIX.—NO. VIII. 50 750 The Relations of Mind and Matter. f August, temperature are checked by some sort of protective covering, while largely in the Invertebrata, and to some extent in the Ver- tebrata, the effects of touch are diminished by a thick armor of ` scales, horn or shelly matter. In the sessile and inactive forms only a small portion of the body is usually exposed to sensory influences, the remainder being incased in solid armor through which no ordinary impression can penetrate. As animals grow superior in organization, however, the need of swift and varied motion renders this hard covering a disadvan- tage, and it is thrown aside, exposing the whole body to the assaults of energy, while the organs of special sense grow con- stantly more and more delicate and varied in their susceptibility. In these cases, then, the body is invaded by an enormous multi- tude of sensory currents, which, could they all reach the muscles, would cause a serious loss of physical energy. To check this inflow the second method referred to comes into play. The nerve currents are forced to traverse ganglia and pass through the fine fibrillz of the cells, which, like fine wires in the electric circuit, check the current, only permitting a portion of it to pass, while the remainder outflows into the ganglion as heat, or is converted into some more special mode of energy. But this alone would not answer the purpose. In all high animal organisms it is necessary that the inflowing energy should be under special control. Some power of discrimination must exist, or must arise through the action of natural selection, to ` decide which currents of sensation shall pass onward to the mus- — cles, and which shall be partly or completely checked. Only in this way could the nerve currents be prevented from calling up © general and indefinite muscular responses, instead of the particu- lar and well adapted responses necessary to yield the motions demanded by the best good of the economy. This is the third element in nerve evolution, and needs now to be considered. It is well known that the nerve fiber is a very imperfect con- ducting material as compared with the metal of the electric cir- _ cuit. How it conducts is an unsettled question. Its current resembles that of electricity in being simply a motor influence, i perhaps i in both cases set free by chemical change at the starting ~ point of the circuit. Whether it resembles electricity in being a -= Sort of radiant vibration through solid matter cannot be told. All * ve know is that its onward movement is excessively slow as 1885.] The Relations of Mind and Matter. 757 compared with electricity, and that the peculiar conditions of the instigating influence persist in the current. Yet though the nerve current moves slowly there is no indication that it meets any check in the conducting fiber or in the organ of sense reception. Probably every motor influence that can make its way through the outer surface to the nerve endings, of sufficient vigor to in- duce chemical action in or otherwise affect these endings, pro- duces a nerve current without reference to its character. And every such current received by the nerves is transmitted and appa- rently even strengthened as it flows inward. How is it, then, that some such currents pass directly onward to the muscles, while others are checked and disappear as cur- rent influences? There is strong indication that the ganglia per- form this duty. The diminution of the diameter of the fiber in the nerve cell is a precise equivalent of the method adopted to produce the same effect upon the electric current. But the point here to consider is that of the evident discrimination displayed. In the sympathetic nerve system there is no evidence of such dis- crimination. There is a checking influence exerted, but it acts upon all currents alike. Each fiber probably passes through a chain of ganglia, each of which lowers the intensity of the cur- rent until itis finally unable to force its way further. Thus the distance to which a sympathetic current will flow depends upon its original strength. When, for instance, in the process of diges- tion the sympathetic nerve extremities are excited by the-contact of food, certain muscles are affected, and produce the peristaltic movement of the intestine. If the contact influence is slight, this movement will be slight and local. If contact be vigorous the effect will grow more energetic and extend further, while a wider range of glands will be excited to action. If the contact influ- ence be abnormaily vigorous the effect will pass onward from the sympathetic to the spinal nerves, and the cerebrum be notified of the abnormal condition, while its motor lines of connection with the sympathetic nerves will be called into activity. We have every reason to believe that it is the ganglion not the fiber that thus diminishes the energy of the current. And the distance to which this current can travel depends on its vigor and the num- ber of ganglia through which it is able to force its way. ` The same is the case with the cerebro-spiral nerve system. Nerve impulses of a character that ıs usually checked may force 758 The Relations of Mind and Matter. [August, their way inward if exceptionally vigorous, and act upon the mus- cles. And significantly, in such cases, the motion produced is not special and definite but vague and general. The impulse, when it has forced a passage through the ganglia, does not select one motor channel in preference to others, but makes its way over the most conductive portion of the general motor system and calls many widely separated muscles into action. In this we have an indication of the original action of the nervous system, such as existed before specialization began and such as yet seems to exist in the sympathetic system. The action of the ganglia, then, appears to be at once repres- sive and discriminative. Certain motor influences seem more capable of forcing a passage through the ganglionic resistance than others. The principle here involved seems to be that every- motor influence of a new or unusual character is resisted, and ready passage is only allowed to motor influences to which the fibrilla have become adapted. And here natural selection has come actively into play. Let us suppose the animals of a cer- tain species to be subject to a definite series of motor impressions, each of which makes it way through the gangliar obstruction and tends to flow out generally to the muscular organs. Yet being insufficient in quantity to occupy every nerve, it will follow the largest, or those over which it finds the most open channel. Thus while the responsive movement might be somewhat gen- eral, certain muscles would obtain a surplus of the current and respond more vigorously than the others. In such a case natu- ral selection must rapidly operate. The movements of some individuals would prove protective. Others would perish. And on the principle that the current of energy finds easiest way over the channel which it has already traversed, this particular motor influence would pursue its old channel in preference and resisted by the other nerves. In like manner others of the sen- sory impressions might gain other favorite channels, and every Sensation in time produce a particular action, adapted to the high- est good of the animal. But if the nerve fibers are only readily conductive to familiar motor influences, and if the gangliar cells resist all unusual sen- = Sory Currents, another element comes into the situation. It is ‘Rot only a question of the selection by the sensory currents of = certain motor nerves in preference to others, but also of making 1885.] The Relations of Mind and Matter. 759 their way at all through the ganglia. A new sensory current may in some animals pass onward and produce motion. In others it may fail to reach the muscles. Natural selection would act here also, and might preserve the individuals which failed to respond to this sensation. Thus in a single animal some sensa- tions will ‘come to produce a certain motor response, other sensa- tions another response, and still other sensations no response, and only the individual which is affected in just this manner can sur- vive, since any other series of movements or non-movements would cease to be protective. Such an animal would be a cor- rectly adapted reflex organism. No conscious or psychic powers would be necessary for its preservation. The repression of the sensory current by the ganglia is proba- bly a developmental characteristic of animal life. It only became necessary when sensation became active and abundant motor energy penetrated the body. It was absolutely necessary for the good of the economy that every sensation should not produce a motion, and the original nerve cells developed into ganglia, partly through this need of repression. These checked the great mass of the motor impulses, only permitting familiar ones to follow their ordinary channels. Yet such repression was not an intelli- gent one. It was largely governed, in fact, by the comparative vigor of the current. The principle seems to be that every sen- sory current, if sufficiently vigorous, may make its way through the gangliar resistance and affect the muscles. But currents of a special kind, which have already established a familiar channel, need less vigor to make their way through the ganglia, though even these are checked if very feeble. Finally special currents which have been repeated a great number of times may make their way onward even if very feeble. And in every case an abnormally strong current, even if it be of a kind that has estab- lished a familiar channel, will force itself to some extent upon other nerves and produce general and indefinite motions. This is the material out of which natural selection chooses its new adap- tations. Finally a nervous organism thus specially adapted to Surrounding conditions may be hereditarily transmitted, and a special series of reflex actions or resistances become inherent in the species. The next question to be considered is, that of the disposition of this repressed current energy. So far, in accordance with the , 760 The Relations of Mind and Matter. (August, electric analogy, we have considered it as transformed into heat. Such is what must become of it in a purely reflex organism, whose whole duty is to let certain currents pass and to repress others. But only in general cases does the repressed electric current become heat. In particular cases it becomes magnetism, mass motion and other forms of energy. Such seems’to be also the case with the sensory current. As the checked electric cur- rent may be so employed as to produce a permanent condition or modification in certain matter, so is the checked sensory current. Memory results. That is to say that some substance contigu- ous to, or forming part of, the ganglion becomes permanently modified by the checked current of energy and assumes a condi- tion which is persistent. And the change thus produced is not identical in character for every condition of energy, but varies with every variation in the producing cause. Thus the special character of the sensation is indicated in the particular effect it has exerted on the modified substance. Such seems to be the character of memory. It is a condition we produced by a motor influence. But motion can act only upon substance. And wherever it yields a localized, permanent, inhe- rent effect this effect can only be an organizing one, exerted upon some substance. No motor effect can persist unchanged in any substance except it take part in the organization of that substance and produce in it some permanent modification. And it is quite within the limits of possibility that such a new condition may react on the current-bearing fibers and reproduce motor energy in the latter. Such seems to be the characteristic of memory. It is not necessarily conscious. Memory, as a rule, persists out- side the range of consciousness. But it is necessarily a definite and permanent condition in something, and the word something necessarily signifies some substance. Thus the current of motor energy which forces its way from external nature into the body, and is borne inward over the chan- nel of the nerves, yields two opposite effects. When it reaches the muscles its effect is disorganizing. It causes chemical. disin- _ tegration with an outflow of general energy, in which that of the oe nerves is merged and lost. When it is checked in the ganglion | a es it seems to exert an organizing effect, perhaps attended by chem- - ‘ion, or the formation of chemical molecules of a high : order. As to this, of course, nothing can be said, but that it 1885. ] The Relations of Mind and Matter, 761 yields a specialized effect for every special mode of sensation, and that this effect is permanent, the phenomena of memory prove. And no such effect can be produced by motion upon substance except it take part in the organization of that substance. Motion otherwise related to substance must flow out and disappear. Only the motion to which formation is due persists in any aoe or organized mass. Possibly every ganglion has its memory. But it is much more probable that in the continued development of the nervous sys- tem, as superior or more centralized ganglia originated, the function of the lower ganglia became simply distributive, and they ceased to exert a repressive influence upon the current. Thus in a vertebrated animal, for instance, it is not im- probable that the discriminative power of a spinal ganglion lies between its sending a sensory current directly to some muscle or sending it upward towards the cerebrum. It is a question of office. To the extent that reflex action has been established in the Vertebrata this short circuiting is the method pursued. It is the normal method in the sympathetic nerves, whose current makes its way to more and more central ganglia only as it grows . in strength or becomes unusual in character. It is the method in many of the cerebro-spinal nerves for actions that have become habitual, like those of walking, for instance. Only when the regularity of step is in some way interfered with does the sensory current force its way to the cerebrum and arouse conscious- ness. In nerve development, then, an early stage is the appearance of the ganglion with its discriminative and repressive powers and its memory record. A later stage is the appearance of several gan- glia, one more central to the whole nervous system than the others. In this case, as we may conceive, the function of the in- ferior ganglia becomes confined to discrimination between send- ing a sensory current directly to the muscles or onward to the central ganglion. The power of final decision and repression of the current may be confined to the latter, and it may become the sole seat of memory. This centralization makes continuous pro- gress through the lower life forms. It is clearly indicated in the insects, yet here it is doubtful if it has gained ascendency over reflex action, to which the great mass of insect motions seem due. oe 762 The Relations of Mind and Matter. (August, For this reason the loss of the head section in certain insects seems very slightly to decrease their motor powers. As we ascend through the Vertebrata, however, nervous cen- tralization rapidly proceeds. The cephalic ganglion, or mass of cephalic ganglia, grows more and more predominant over the in- ferior ganglia, and the sensory currents are diverted more and more fully towards this central region. Throughout the whole upward range the phenomena of nerve development indicates that reflex action grows less and less, and conscious action more and more declared. In certain fossil vertebrates of huge form, the mass of the inferior surpasses that of the cephalic ganglia, indicating a great degree of reflex action. Throughout the fossil series cephalization seems to steadily increase, indicating a grow- ing superiority of conscious over reflex action. Yet this change was only made by slow stages, and an inter- esting intermediate stage seems to have intervened between reflex and habitually intelligent action. This is the stage of instinct, in which reflex action and consciousness seem to be combined. In this stage the sensory currents, on reaching the inferior ganglia, seem to partly follow an habitual channel to the muscles, partly _ to pursue a channel to the central ganglion, where they awaken consciousness. It is a usual stage in the change from fully con- scious to reflex action. In every such case intelligence may exercise some controlling function, with a possible modification of the reflex action. Finally, in the highest animals, the upward channel has become the habitual one for all but the most deep- seated or incessantly continued sensory impressions, and intelli- - gent has grown more and more dominant over reflex and instinc- tive action, until in man it has become the controlling agent in the great sum of actions, . - There is a principle, already stated, to which this increasing cephalization seems due. The nervous system is not readily conductive to unusual sensory impressions. It has become so to ordinary impressions, each of which has established for itself a habitual channel. But every unusual impression is checked at the ganglion, and can only make its way onward if of consider- able strength, and then over the general motor system, not over _ any particular motor nerves. If this sensation becomes an ordi- _ fary one, natural selection decides whether it shall gain some - Settled led channel of outflow to the muscles, or shall be finally 1885.] The Relations of Mind and Matter. 763 checked at the ganglion. And another result of great importance is that every such unusual impression, thus partly or wholly checked in its course, produces the effect of memory at the gan- glion. Thus a record is laid up in the memory of every unusual impression, which is vivid at first but grows less and less so with every repetition of this impression. Finally, when a particular sensation grows habitual it may cease to affect the memory record. It has already made a deep impression there, and it subsequently is received with less and less consciousness of its existence. If it passes on to the muscles it may do so utterly without affecting consciousness, or become completely reflex. As centralization proceeds it seems probable that all such un- usual impressions are directly transmitted from the inferior to the central ganglia. In this direction there appears to be the freest channel of conduction for sensory currents. Usual impressions may have opened direct lines to the muscles, but unusual ones pursue a more open and general channel leading towards the central organ, in which the final duty of discrimination is exer- cised. And as a consequence, in the higher vertebrates the main center of reflex action seems to have become the ganglia at the base of the brain. In the insects the ganglia of each section seem to exert an active reflex function. This has largely ceased to be the case with the spinal ganglia of man, whose main reflex center is the cerebellum and the contiguous ganglia. In all the higher Vertebrata a nervous organ has been devel- oped which does not seem to exist in the invertebrate animal world. This isthe cerebrum. It is a special gangliar organ de- voted solely to the duty of memorizing, and one in which con- sciousness has become centralized. In the ant, the most intelli- gent of invertebrate animals, there is no apparent differentiation in the head ganglion. It is a single organ, centering in itself duties of reflex and instinctive action, and of memorizing. In the highest animals these duties have become separated. The inferior brain ganglia apparently possess the function solely of reflex action, if we may view as a constituent part of this function the diversion of unusual impressions upward to the cerebrum. That is to say, they have lost all power of checking the flow of nerve energy. Memorizing and psychical action seem confined to the cerebrum. And intermediately sensations of increasing frequency grow partly reflex and partly affect the cerebrum without calling 764 The Relations of Mind and Matter. [August, out any conflicting orders from the intelligence. Such cases are those named instinctive. Their steady course is towards the fully reflex condition. The memory record of them may become so complete, through frequent repetition, that finally they fail to produce any effect, or to arouse consciousness. Cases of this kind are by no means confined to the lower animals, but may be found in some of the most difficult operations of the human sen- sory organism. In the oft-quoted case of the skillful pianist, for instance, as the fingers become habituated to a certain series of movements, attention may be more and more withdrawn from the action until it reaches the instinctive stage, a vague consciousness of the movement perhaps persisting but no intelligent oversight being necessary. Only when some change in the succession of sound is produced, however-caused, does consciousness at once become again active. The element of the unusual has been intro- duced and the sensory current immediately makes its way in its full force to the cerebrum, arousing the powers of the dormant attention. The cerebral organ of man does not seem to be a constitu- ent part of the general nervous system. Its sole duties are con- nected with the evolution of the mind. If it be completely removed animal life does not necessarily cease. But its removal shows to what an extent the life action is reflex. The lower ver- tebrates may continue to live for a long time without the cere- brum, and perform most of the essential duties of life. Yet every trace of memory goes with its removal, and they act only as au- tomata. In insects the life functions are still more fully performed, showing here an inferior dominance of the mental powers. Pos- sibly but for the shock to the organic system by its removal, its function of memorizing might be in part relegated to the cerebel- lum, and the embryo state of a new mental sae oe ak be pro- duced. According to the hypothesis of Professor Christiani, devised from experiments with disbrained rabbits, the cerebrum forms a kind of secondary circuit, into which a large portion of the ener- gies enter and are stored up, while the basal ganglia form a pri- Mary circuit, which transforms the energies into reflex motions. He found that with the removal of the cerebrum all energy was nsferred into reflex motion, so that disbrained and snes | ouna ot: Physiological Society, June 20, 1884. 1885.] The Relations of Mind and Matter. 765 animals displayed much stronger reflex action than normal ones. In normal animals much of this distributed energy ascends to the cerebrum, where it becomes converted into consciousness and ideas. According to Luys the optic thalami are intermediary sensory organs interposed between the purely reflex phenomena of the spinal chord and the activities of psychical life. So the corpora striata are seated at the summit of the motor nerve system. Thus it becomes a question of gangliar discrimination whether a sen- sory impression, on reaching the optic thalamus, shall be at once transferred to the corpus striatum and thence through the motor nerves to the muscles, or shall proceed to the cerebrum and — motor impulses descend to the corpus striatum through that channel. In this latter case we venture to hypothesize that all reflex action vanishes, and that all sensory impressions that ascend to the cerebrum end there. If subsequent action take place it must be in response to new initial energy emanating from the mind and wholly governed by the intelligence. These considerations lead to the idea that the cerebral organ may be in an anatomical sense a secondary circuit. That is, that the nerve fibers of the body may not be in direct communication with the cerebrum. It may be possible that the sensory fibers that enter the basal ganglia are continuous through the nerve. cells only with the outgoing motor fibers, and that the cerebral fibers which enter these ganglia form a circuit of their own through fibrillz of the same cells. In sucha case the influence of the primary on the secondary nerve circuit could be inductive only, and we would have a mechanism similar to that of an elec- tric inductive system. This idea of course can have no warrant in experiment, but it is offered as a suggestion that the many close analogies between the nervous and the electric current may be completed by a condition like that of induction, which plays so prominent and important a part in electric phenomena. The sheathing of the nerve fibers by the medulla seems to be an insu- lating apparatus. Their naked condition in the ganglia must -favor induction, and renders it possible both that the transfer of a sensory current to two or more outgoing nerves may be through induction between the fibrillz, and that its transfer to a cerebral nerve may be through induction. It is not impossible, indeed, that the check to the sensory current in a ganglion may arise - 766 *The Relations of Mind and Matter. [August, through inductive transfer of its energy to a series of fibrillz which are short circuited in the ganglion and make no connection either with ingoing or outgoing nerves. This hypothesis of an analogy between the action of the ner- vous current and that of electric induction is at least of some in- terest, and may be further pursued. We have argued that to this checked current the phenomena of memory are due. If it arise from the transfer by induction of the sensory current to a series of fibrillæ, forming a secondary short circuit through the gan- glion (continuous, of course, as all inductive currents must be), then we would have here a new apparatus for the operation of organic forces, and one leading directly to the development of a separate cerebral organ. For, as above considered, in the devel- opment of the nervous system the check to the sensory current in the ganglia became a duty of growing importance, and the volume of checked energy steadily increased with the growth of nervous susceptibility. If, then, this check took place through the action of a separate inductive circuit, this apparatus must have developed with its increase of duty. At first confined to the same cells which transmitted the reflex current, the inductive fibrillæ may have grown in length and number, and in time gained cells of their own, with connecting fibers. Through these cells the checked current would produce its final effect, whether of memory conditions or otherwise. By a continuance of such a process the cells of the inductive circuit might become separated entirely from those of the primary circuit, forming first a cerebral layer upon the central reflex ganglion, and finally a completely separate ganglion connected only by nerve fibers with the system of reflex ganglia. Such is conceivably the mode of origin of the cerebrum, and the character of its nerve relations with the nerves of the reflex system. As intelligence grew and the great mass of sensations were transmitted to the cerebral circuit, this organ would neces- sarily greatly develop, until from a series of secondary fibrille short circuited through one or a few cells, it became the great cerebral organ of man, with its highly important function of the ae evolution of the mind. oS may very briefly recapitulate the conclusions to which the regoing arguments have led. The motor energy of the exter- nal ate makes its way in various forms or phases into the ani- 1885.| Affinities of Annelids to Vertebrates. 767 mal body by the channel of the sense organs and the sensory nerves. Reaching a ganglion it is received by the cells, perhaps by many of them through the division of the fiber into its con- stituent fibrille. It either continues over its original fibrille to the motor nerves which issue from these cells, or is transferred, partly or wholly, to other fibrillæ by induction. In sucha case it may be carried to other motor nerves, or enter upon a short local circuit and yield the local effect called memory ; that is, a peculiar organizing effect in which is represented its peculiar character. Or this secondary circuit may convey it toa higher or more central ganglion, in which the same modes of distribu- tion may be exercised. In highly developed animals it may pass through several such intermediate ganglia, and be finally, in part or wholly, transferred by induction to the cerebral ganglion. In this it exerts but one action, that whose effects we call memory, a permanent transformation produced, in some organizable sub- stance. This effect is the germ of all mental development. (To be continued.) :0:— AFFINITIES OF ANNELIDS TO VERTEBRATES. ` BY E. A. ANDREWS. LS a group the annelids exhibit in a prominent degree both bilateral symmetry and segmentation. The former is well expressed in the adult, in the early larval stages and even at the period of closure of the blastopore, when the radial symmetry of the gastrula becomes replaced by bilateral symmetry. Segmentation, so pronounced in the adult, is not found in what we may regard as the most primitive larval form, the Trochoph- ora of such forms as Serpula, or as more perfectly expressed in some species of Polygordius. These two fundamental characters, bilateral symmetry and seg- mentation, naturally lead to a comparison of this group with the other segmented Bilateralia, of which the Vertebrata especially have attracted attention in seeking for the allies of the annelids , or rather in the attempt to derive the vertebrates from inverte- brate groups, the annelids have furnished important ai Of those who have paid especial attention to the subject and who maintain a close relationship between the annelids and verte- brates, may be mentioned Semper, Dohrn and Hatschek. Sem- per seems to have advanced the most evidence in support of his % 768 Affinities of Annelids to Vertebrates. [August, views, working mainly from the standpoint of comparative anat- omy, and drawing little or no material from the larval stages of annelids. His views may be briefly (and thus necessarily imper- fectly) stated as follows: Regarding the distinction of ventral and dorsal surfaces as of little morphological importance, we may make a direct comparison of annelid and vertebrate by supposing the mouth of the annelid to be a new formation, and that a mouth once existed upon the hemal (dorsal) side of the annelid which was homologous with the mouth of the vertebrate (Figs. I, 2).

In the formation of these structures from STRT tissue and from more indifferent embryonic cells, 1885.] Affinities of Annelids to Vertebrates. 769 Semper finds an identity in fundamental plan between annelid and vertebrate. Though establishing so many homologies be- tween the two groups, he does not derive one from the other, but inclines to the view that both are descendants of a segmented planarian-like ancestral form which on the one hand gave rise to the vertebrate group by the enlargement of its anterior ganglion to form a brain and by the union of its separate nerve cords along the dorsal side to form the spinal cord, while on the other hand the annelid was formed by the acquirement of a new mouth piercing the nerve cord or passing between the still separate nerve cords and by the closure of the primitive mouth. Dohrn’s views on the affinities of the annelids to the verte- brates are very interesting, if perhaps of less importance as being purely hypothetical. $ D — V Fic. 3.—Diagram i vertebrate according 2 Dohrn.

Homologizing the dorsal surface of one group with the ventral of the other, he finds the necessity of supposing a new mouth to have existed in one group, and unlike Semper regards the verte- brate as the form in which this new structure was formed (Figs. 3, 4). Seeking a trace of the primitive mouth of the vertebrate homologous with the mouth of the annelid, which is on the neu- ral side, he finally concluded that the fossa rhomboidalis of the vertebrate represented the area of the nervous system formerly pierced by the cesophagus on its way to a neural mouth, there being thus a circum-cesophageal ring formed homologous with that of the annelid. The present mouth of the vertebrate was thus a new formation having no homologue among the annelids. 770 Affinities of Annelids to Vertebrates. [August, The genetic relationship of the two groups he conceives to have been that of diverging branches from a common ancestor. This hypothetical ancestral form was a segmented annelid-like creature with a chorda, gills on all the segments, supported by a cartilaginous rod on the side of each segment, with a neural mouth like that of an annelid and with a pair of segmental organs in each segment opening to the exterior and also inter- nally into the digestive tract. From this ancestor the vertebrates arise by an interesting series of modifications in structure due to “change of function” of the primitive structures; some of the segmental organs gave rise to the mouth and branchial clefts, while others formed the genital and urinary ducts and even the anus; the branchiz were variously modified to form the branchie of the vertebrate, its fins and limbs and perhaps the external gen- ital organs ; the cartilaginous supporting rods gave rise to the ribs, skeleton of the limbs and part of the skull. This hypothetical ancestor was more highly specialized than the present annelids, which have since degenerated, perhaps (he thinks), owing to the sharp competition between the more annelid- like and the more vertebrate-like forms of the common ancestral group. The whole tenor of Dohrn’s work inclines to the conclu- sion that annelids, like ascidians, etc., are degenerate vertebrates. However satisfactory in explaining an origin of the vertebrates from an hypothetical ancestor this hypothesis may or may not be, it apparently is unsatisfactory in so far as it concerns the annelids. Much of the evidence in support of Hatschek’s views is derived _ from a consideration of the development of annelids, both of . Polychztz and of Oligochetze. His comparison of the two groups, annelids and vertebrates, is essentially that of Dohrn’s (Figs. 3, 4) except that he does not place the point where the primitive cesophagus pierced the ner- vous system at the fossa rhomboidalis but at the hypophysis cerebri, a position more comparable to the present position of the mouth among the annelids, as it is farther forward, in the unsegmented - Portion of the head. He reduces the excretory organs in both groups to a common type represented by a transient stage in the 2 larva of certain annelids when the branched excretory tube in the head ofa Trochophora larva sends back a branch into the trunk, hos apnd tube sie rise to = segmental tube in each 1885.] Affinities of Annelids to Vertebrates. 771 segment of the trunk, and thus a stage is present where the seg- mental organs are connected by a common longitudinal duct. In the annelid this connection is lost. (though perhaps retained in a few), while each segmental organ acquires an external open- ing. In the vertebrate the primitive connection persists, and no external opening is developed for each segmental organ. The conclusion reached by Hatschek is that annelids and ver- tebrates have had a common segmented ancestor, which did not differ much from such a simple annelid as Polygordius. The three authorities now mentioned represent sufficiently the views of those finding more or less close relationship between the vertebrates and the annelids; there are others who regard this relationship as very remote, if existing at all, either placing other invertebrate forms nearer the vertebrates or separating this group from the annelids, from consideration simply of the funda- mental differences of the two groups. Among the latter may be reckoned Mr. Adam Sedgwick, whose ingenious hypothesis in- , cludes the question of the relationship of these two groups, though advanced with the much wider object of accounting for segmentation and the origin of the Triploblastica from ccel- enterate-like forms. Founded upon the behavior of the blasto- pore and upon the structure of the ccelenterates, the hypothesis calls for a coelenterate-like ancestor with mouth and anus part of one common opening to the digestive tract which bore diverticula on each side, indicating a segmentation, and communicating with each other as well as with the exterior; the nervous system formed a broad ring around the mouth-anus (Fig. 5).

[August, and by loss of the connections of the lateral pouches with one another and with the digestive tract, thus forming the seg- . mented body-cavity and the segmental organs. The vertebrate was formed by a more complete union of the lateral parts of the nerve-ring between the separated mouth and anus, together with disappearance of its two ends, by the persistence of some ante- rior pouches to form branchial clefts, by the loss of external openings for others which remained connected with one another and with the digestive tract at one point to form part of the body- “ cavity and the urogenital ducts, and finally by the retention of only the outer openings of the last pair of pouches which form part of the body-cavity and the abdominal pores. Mouth and anus are thus homologous in the two groups, and primitively neural in position; the mouth in the vertebrate acquired its pres- ent ventral or hæmal position by advancing around the anterior end of the body.

A still more remote separation of the annelids from the verte- brates is required by the comparisons instituted by Goette from a study chiefly of the development of planarians and annelids ; the fundamental ground-plan of the two groups is, he thinks, essen- tially different, as shown by the entirely diverse ways in which the gastrula is modified in the two to form the adult. In the __ annelid the blastopore closes along a line which corresponds to _ the longitudinal axis of the adult, the mouth being formed from _ its anterior part and the anus near its posterior end; the nervous _ cord is formed along this line of union of the lips of the blas- topore. Thus the ventral surface of the adult represents the 1885.] Affinities of Annelids to Vertebrates. 773 blastopore area of the gastrula—the area opposite the upper end (summit) of the gastrula and in a plane at right angles to the chief axis of the gastrula,and along this ventral surface or blas- topore area the nerve-cord is developed. In the vertebrate, on the contrary, the blastopore closes in a small area representing the posterior end of the adult and entirely behind the nervous system, corresponding in part to the anus in position. The blas- topore area being thus the hind end of the adult, the ventral sur- face of the adult is formed from one side of the gastrula while the nerve-cord develops upon the opposite side of the gastrula in a position more nearly parallel with the chief axis of the gastrula. In an annelid, then, the ventral surface with the nerve-cord cor- respond to the original lower or blastopore surface of the gas- trula, and the mouth represents the anterior end of the blasto- pore. In a vertebrate the ventral surface corresponds to a side of the gastrula, while the surface homologous to the annelid’s ven- tral surface is found represented in the vertebrate merely by the anal region, this being the blastopore-area of the gastrula; the mouth in the vertebrate is a new structure formed remote from the area of the blastopore, and not at all comparable to the annelid mouth except in function. Figs. 8 and 9, copied from Goette’s work, will serve to illus- trate this comparison of the two groups. VM i CMM nn Fig. 8. Fig. 9. G. 8.—Dia ye of annelid according to Goette.

The preceding statements may serve to indicate the chief views upon the subject, showing how much difference prevails in the - -hypotheses advanced to solve the important morphological prob- lem of the exact affinities of the annelids and vertebrates, and at the same time indicating, perhaps, a tendency among those who have recently investigated the embryology of the annelids to 774 The use of Copper by the Delaware Indians.

BY CHARLES C, ABBOTT, M.D. N the American Antiquarian of November, 1884, Mr. Edwin A. Barber, speaking of the Indians of Pennsylvania, re- marks : “The copper age is represented by a few specimens of copper implements which have been discovered in different localities ; but these could earkaly have been produced by the Lenni Lenape tribe. They were doubtless obtained from the ancient miners of Lake Superior, or at least were the remains of the industry of the mound-building race, which had found their way into Penn- sylvania. Referring in 1881 to the use of copper, by the New Jersey tribes, I also expressed the opinion that it was “not improbable _ that all the copper articles found along the Atlantic coast, were brought from western localities.”! A careful re-survey of many localities where ordinary Indian stone implements occur in abun- dance; and correspondence with collectors in various portions of New jersey and Eastern Pennsylvania now convince me that the use of copper, as implements and ornaments, was much more common than I supposed, and that among our Delaware Indians were many coppersmiths. In the fifteenth annual report of the Peabody Museum of American Archzology, Professor Putnam describes two exam- ples of copper spears, of which he says, while “ these spear-heads closely resemble one in the State Historical Society of Wiscon- sin,” yet they differ in the important feature of having smooth edges, while the Wisconsin specimen has a serrated point. These _ were both made “ from a mass of native copper, hammered into = anaes as shown: by several small laminations which can be dis- From the same locality a third example has been found (Fig. 1) ; re Industry, p. 413.

Associated with the three spears was a small celt differing i in no respect from scores of such fii} objects found in Pennsylvania AK and New Jersey. The illustra- Nf tion (Fig. 2) represents the speci- $ men, of actual size, and needs no detailed description of the object. Suffice it to say that the |% evidence of its having been ham- ți we AN mered into shape is as patent as i i in the examples of spear-heads (WW f described by Professor Putnam. f Recently I have had the op- portunity of examining a large collection of Indian antiquities, made in the neighborhood of Reading, Penn. and about Bristol in the same State.

They are of much interest, however, as showing that more of such objects were in use than has been supposed, and proportionately as the number found here increases, does the probability of their having been brought from a distance decrease; for there is found both in Eastern Pennsylvania and in New Jersey, a very considerable amount of native copper. Indeed one mass weighing over one hundred pounds has been found in Somerset county, New Jersey. Besides celts and spears there have been found many orna- ments of copper, which clearly showed that they were made by the same hammering process; and the character of the metal showed, in many cases, that it was identical with the nodules of 776 The use of Copper by the Delaware Indians. {August, impure native copper found in this region, and not, therefore, metal derived from the Lake Superior region. When the Delaware and Raritan canal was dug, in 1832, there were found many skeletons of Indians during the course of the excavations. About the wrist bones of many were narrow bands of hammered copper, and some large crescent-shaped ornaments were also found. In one instance a grave was opened which con- tained a nodule of native copper weighing thirteen ounces. This information was derived from a gentleman who saw many of the objects mentioned, and who carefully examined the skele- tons and grave contents as they were brought to light. Although the specimens have long since been lost, their identi- fication as copper objects of Indian manufacture was carefully Fic. 2.—Copper celt from Trenton, New Jersey. | made ; and as this is information not readily obtained and has a distinct bearing upon the question of the use of copper among our Indians, it is worthy of being put upon record. In the many small collections of Indian relics made in different localities that I have examined, I find that one or more celts, spears, arrow-points, bracelets, rude beads or fragments of sheet copper are sure to be found, and a tabulation of these objects, and the information derived from correspondence, gives the fol- _ lowing results: Celts, 11; spears, 5; arrow-points, 8; bracelets, 13; beads, aes Eabitients of metal, 21; in all, 128 jects: When we con- _ sider how small a chance there i is of such objects being found, ‘acs what a small proportion | of such as are recovered come to - ledge of , it is a most reasonable presump- 1885.] Editors’ Table. Cor; tion that the Indians had a more familiar knowledge of copper than merely as a material, ready-wrought, which they could only procure through barter with far distant tribes. There is yet another feature which should be briefly dwelt upon. Among the fragments, so-called, of hammered copper, are several which have every appearance of being unfinished objects. One is, I think, intended for a finger ring, such as those from Ohio, described by Professor Putnam ; and another strongly sug- gests those curious large ear-rings of which that author found so many specimens in recent mound explorations. It would appear, then, from an examination of the copper objects found in Pennsylvania and New Jersey, that the weight of probability is strongly in favor of their home manufacture ; and the similarity of the forms to those taken from areas where mounds occur is another fact in favor of the rapidly growing im- pression that the builders of these earth-works and the Indians of the coast were essentially one people. ——:0:—— EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. Just and courageous criticism is necessary to the main- tenance of excellence in all departments of human activity. An indisposition to submit to it on the one hand and a fear to exer- cise it on the other, are sure indications of the weakness or decay of an important element of character. Even unfair criti- cism, bad though it be, is better than none, as it gives indication of life, and is sure to be itself corrected in the end. The attempt to suppress criticism is an unwise proceeding, which will react on its authors. It is better to “ make a clean breast,” if need be; and if facts do not require it, this also can be made plain. The force of just criticism is not weakened by suppression, but is rather increased in energy; while the expression of it draws the fire and silences the gun of the critic. It is a great error to confound criticism on behalf of the truth with personal hostility, yet it is an error by no means rare. To occupy a per- fectly judicial attitude towards our own productions requires some moral elevation, which all men do not attain to. Unjust criticism, indeed, is ground for complaint against the critic. ~ 778 Recent Literature. [ August, Hence if the critic deserve the name, justice only will be his in- fallible guide. People of sensibility and refinement shrink from controversy ; and the enervated and dishonest endeavor to avoid it alto- gether. But it cannot be escaped without a total withdrawal from the field of action, or an attainment of perfection such as rarely falls to human lot. In the scientific world all the aspects of this question come before us from time to time. We meet the sometimes brutal vigor of German truth-telling, contrasted with the dexterous fencing of French elegance and skill. We meet with inexcusable rashness or misrepresentation on the one hand, and with subservient cowardice or fulsome adulation on the other. In our own country science is none too strong in criticism. With here and there healthy exceptions we have a good deal of paraly- sis in this direction. In a few quarters the indisposition to accept fair criticism is marked. But there is enough virility in our sci- entific community to accustom such weak brethren to this one of the phases of “ the struggle for existence,” by administering more criticism in judicious quantities so long as their cases may seem to require it. If the bureaus of the Government would send their return receipt with or in the publications they issue, every one concerned would be greatly accommodated. The return receipts would then be promptly returned, whereas as now sent at another time, it requires time and trouble to identify the package referred to, which sometime Tesults in a failure to return the receipt as desired. We are sorry to see our cotemporary Mind in Nature ad- mitting to its columns articles like that of Professor Piper on evo- lution. If the author had spent his time in studying field mice, OF garter-snakes, or trout, or minnows, he would have learned to know something of the subject on which he writes so fluently. :0: RECENT LITERATURE. -De CANDOLLE’S ORIGIN OF CULTIVATED PranTts.!—Two years ago the French edition of this book made its appearance, and 3 n — s Evorety received and noticed Pile the botanical og al Tt ee of the Academies of St. Puenburp, Stoc kholm, Berlim, Munich, &c., &c rk, D.

This edition is, therefore, somewhat more than a mere translation, and partakes of the nature of a new edition. The purpose of the book may be given in the following para- graph in the preface: “I have always aimed at discovering the condition and the habitat of each species before it was cultivated. It was needful to this end to distinguish from among innumera- ‘ble varieties that which should be regarded as the most ancient and to find out from what quarter of the globe it came. The problem is more difficult than it appears at first sight. In the last century and up to the middle of the present, authors made little account of it, and the most able have contributed to the propagation of erroneous ideas. I believe three out of four of Linnzus’ indications of the original home of cultivated plants are incomplete or incorrect. The book is divided into three parts. In the first we have a general discussion of the epochs of cultivation and of the method of discovering the origin of cultivated species. In the second part plants are taken up systematically and discussed as to their origin. Thus we have first those plants which are cultivated for their subterranean parts, next those cultivated for their stems or leaves, then those cultivated for their flowers or the organs which envelop them, next those cultivated for their fruits, and lastly those for their seeds. In part third we have interesting summa- ries and conclusions, accompanied with various tables of species. In all the author has examined 247 species, of which 199 originated in the old world, 45 in the new world, with three whose origin has not yet been determined. “An noteworthy fact is the sages in some countries, of indigenous cultivated plants. * e United States, in spite of its vast territory which the aide: a statement which air dy overlooks our ex- cellent grapes which are derived from several native species, our E n raspberries and strawberries. age 460 we find the remark: “ I have not observed the slightest indication of an adaptation to cold.

Every fruit grower in the Northern States knows well that certain varieties of these trees will endure the winter while others will not. This may not be due to any adaptation to cold, but it certainly does not admit of the simple explanation given by the learned author. There have certainly been variations in the hardiness of cultivated plants, and these variations have, by judicious selection, made it possible for us to extend very consid- erably the range of the species.—Charles E. Bessey. Our Living Wortp.—Under :this title Mr. Selmar Hess, of New York, is publishing in forty-two quarto numbers a popular | work on natural history, which will be welcomed by young peo- ple on account of the abundant and showy illustrations. The text is based on Rev. J. G. Wood’s, and is anecdotal rather than scientific ; it has been adapted for American readers by Dr. J. B. Holder. The wood-cuts are those which have appeared in Wood’s book, also in Brehm’s Thierleben, while the colored plates are oleographs reproduced by Prang from the exquisite chromo-lithographs of the great work of Brehm As a picture book of the animal creation, particularly of the vertebrates, it will prove attractive. The accompanying illustra- tion of that strange animal the Capybara, the “ native hog” of South America, the largest of existing rodents, will give an idea of the kind of illustrations used in the numbers we have thus far received. While, then, not specially authoritative or American in its plan or authorship, we doubt not that it will be welcomed by many as a readable “ natural histo As respects the classification adopted, the arrangement should be such as is generally followed by modern zodlogists. To place the marsupials between the land Carnivora and the seals is a vio- lation of the simplest principles of classification. The Insectivora and bats are placed too near the primates, although it should be said that the position of these groups is in dispute. ae work will be issued in forty-two parts of forty-eight pages cents a part; it will contain forty-two oleographs and NSE full-page wood engraving. The paper and press-work are excellent. MEMOIRS oF THE NATIONAL AcApemy oF Scrences.—The third volume of the National Academy appeared in 1884 from the vernment printing office. It is a quarto volume of 262 pages, _ and contains four memoirs read before the academy in 1884, _ under the following titles: Report of the Eclipse expedition to Caroline island, May, 1883; Experimental determination of wave- = lengths in the invisible prismatic spectrum, by Professor S.

The greater part of the volume is devoted to the report of the eclipse expedition, the interest of which is enhanced by the photographs reproduced in its pages. Caroline island is a genuine atoll, of the type described by Darwin and Dana; while the frontispiece gives a bird’s-eye view of the low circular island, the four accompanying illustrations will convey an idea of the scenery of a Pacific atoll. e sur- face of the island is covered with palms and undergrowth, in- cluding a large number of young cocoa palms planted by the own- ers of the island, who keep a few people on the island to cultivate them. Beside the eclipse and other physical data, the botany of the island is described by Dr. W. S. Dixon, U.S.N., and Professor W. Trelease ; Dr. Dixon also adds notes on the zoology of the island. The few butterflies have been named by Messrs. Arthur Butler and H. Stricker. The whole presents an interesting mon- ograph of an atoll, Plates xxvilI-xxxi are from electrotypes of four of the views taken on the island. Dr. Krauss’ Stavic Customs.—In his latest publication, the ethnologist Dr. Friedr. S. Krauss has taken up the subject of the tribal and family relations, of domestic life, courtship, mar- riage, married life, divorce, adoption, widowhood and hospitality among the Southern Slavs of the Balkan peninsula. From the title, “ Sitte und Gebrauch der Siidslaven” (Customs and uses among Southern Slavs)! we would certainly expect a full treat- ment of other subjects of popular life, also, as of legal customs, agriculture, pastoral pursuits, etc., included in the volume; but what is offered is so well marked with the stamp of learning and thoroughness that we do not grudge with the author for the rest, expecting to find it in subsequent volumes. The work was un- dertaken in 1883 under the auspices of the Vienna Anthropolog- ical Society, and carried out through the munificence of Baron Ferd. von Andrian-Werburg. A considerable literature already exists on the subject, as may be collected from the preface of another important work of Krauss (on the Folklore of Southern Slavs, a serial, of which two volumes have hitherto appeared), but the author is perfectly independent of his predecessors, has himself visited a large portion of the countries described, an speaks several of their dialects. The “Customs” are inter- spersed with many quotations from Slavic poets and from popu- lar poems, of which the authors are unknown, sometimes also with quotations from the original languages. But he avoids on purpose ethnologic comparisons with facts taken from non-Slavic especially non-European institutions, as the conditions under which they originated may not always be the same as the ones observed at home. It is interesting to see how the tribe of the 1 Sitte und meant der ag peng Nach heimischen gedruckten und ungedruck- » Kra ten quellen, von Dr. F. S. Krauss. (Wien, 1885. A. Hilder, publisher.

Nevertheless a certain spirit of poetry hovers over these populations, which are isolated from the rush of the world’s commerce and have been so long subject to the iron rule of the Turk. Their love for music, poetry, dance, mimicry and fairy tales lets them forget many of their tribula- tions and miseries of everyday life, and here in Krauss’ book are gathered the most naive and surprising utterances of the popu- lar spirit. - The long and useful alphabetical index was made by a young lady of the village of Mikanovci, whose name is men- tioned in the preface —Alvert S. Gatschet. Kincs.ey’s Mapam How anp Mapam Wuy.—Charles Kings- ley was no ordinary man, and no ordinary writer, and the repub- lication among the Globe Readings of his little work, Madam How and Madam Why, will doubtless be welcomed by many of the class of little ones for whom it was written. It is true that to an adult the impersonation of method and reason as “ Madam How” and “ Madam Why,” and that of analysis and synthesis as giants seems too metaphorical and somewhat old-fashioned, yet the charm of the style cannot be denied. A deeper objection to the title is, that we do not know the “ how ” or “ why” of any- thing—we name the forces which move nature’s scenery, but we understand them not. No one knew this better than Charles Kingsley, as may be seen by what he has to say with regard to analysis and synthesis. As a book for American children the value of this treatise is impaired by the fact that all the allusions and illustrations are European, or rather British.

Asta.— The Sanpo and the Trawadi.—The chief paper inthe May issue of the Proc. Roy. Geog. Society is upon the disputed question of the sources of the Irawadi. As no one has yet followed the Sanpo from Thibet downwards, it is still unproved whether it enters the Irawadi or the Brahmaputra. Mr. Robert Gordon opposes the commonly received idea by advocating the Irawadi view. He bases his belief upon the following points : (1) The Salween, which flows to the east of the Irawadi, has been proved to rise north of latitude 30°, and thus the country _which was formerly supposed to supply the Irawadi is now known to be the watershed of the Salween (2) The Irawadi at Bhamo, the ‘point where it first became known to western geographers, is still one of the largest rivers in the world, containing probably two-thirds of its volume in the delta. The average discharge at the delta is about 521,794 mil- lions of cubic yards, very nearly four-fifths of that of the Missis- ippi. But three-fourths of this vast discharge come down in the months of July, August and September. August has twenty-two , per cent of the entire discharge, February and March only one a and a half per cent. At Bhamo Mr. Gordon calculates the ordi- _nary high-water capacity at B80; 000 cubic feet per second. (3) Chinese geographical annals, extending over twelve hun- -dred years, and corroborated by the direct statements of French _ missionaries and others, give direct evidence that the Sanpo is -~ -the Irawadi, and maps, names of rivers, etc., gime indirect evi- | to the same effect. - adit Gordon quotes Count Sushen as follows : “ Almost all the who could furnish information about this country akeen answer to my question, ‘Where does this river come om? ‘From Lassa.’ According- to Chinese and Tibetan Tats department is edited bř W.N. LocKiNGToN, Philadelphia. 1885.] ` Geography ana Travets, 785 sources, the Irawadi is no other than the lower course of the Tibetan Sanpo.” Not only do the old Chinese geographers connect the Sanpo with the Irawadi,.but the Chinese official map, made after the surveys of the French missionaries in the last century, does the same. The imperial geography of the Thung dynasty (617-907 A.D.) says that the great Kin-sha-Kiang is made up of two rivers and then passes by Mano and Tchenago (Bhamo and Tshempenago). It adds: “There is no doubt that this river is the Yaroo Sanpo' of Thibet.” The Emperor Kang-hi says that the Yaroo Sanpo enters the kingdom of Burma. The Yunnanese call the Upper Irawadi the Ta-Kin-sha-kiang, or Great Kin-sha river, while the Yang-tse-kiang is the Sui Kin-sha-kiang, or Little Kin-sha river, Ta-Kiu-kiang, the official Chinese name for the connecting link between the Sanpo and the Irawadi is identical with Nam-Kiu-long, the name given by the Shans who live upon it, both meaning the Great Kiu river. The explora- tions of Hindoo surveyors have carried the Sanpo to the east of the point where it was formerly supposed to enter Assam, but the lower courses of the affluents of the Brahmaputra were immedi- ately twisted upon the maps so as to still show the union of the Sanpo with the Brahmaputra. (4) It is impossible, on the supposition that the Zayul-Chu is the upper course of the Eastern Brahmaputra and the Sanpo that of the main branch of that river, to account for the volume of water in the Irawadi at Bhamo. A drainage area of from 5000 to 8000 square miles, which is all that could in sucha case be left to the Irawadi, could not possibly yield so great a volume. (5) The Zayul-Chu, which is said to be the Eastern Brahma- putra, may prove to be an affluent of the Irawadi. Mr. Gordon goes into elaborate arguments to show that Rima and Sama, places upon this river, are some. thirty miles farther to the north-east than they are placed by Captain Wilcox (who did not visit them). In this half degree there is room for the Sanpo to flow to the Irawadi. The volume of the Zayul-Chu is greater than that of the Upper Brahmaputra. (6) The Brahmaputra influents, even if the Sanpo is barred out by the range of mountains upon its southern and eastern borders, have basins sufficiently large to account for their dimen- sions. The Subansiri has 7000 square miles and a discharge of 240,000 cubic feet per second; the Eastern Brahmaputra 7000 Square miles with 326,000 cubic feet, and the Dihong, which some believe to be the Sanpo, would without it have 7500 to 12,000 square miles, which, in the rainy climate of the southern slopes of the Himalayas, would account for its volume of 423,- 000 cubic feet per second. In reply General J. T. Walker attacked particularly the argu- ments connected with the Zayul-Chu, certainly the weakest part of Mr. Gordon’s paper. 786 General Notes. [August,. Corea.—According to Mr. Carles there is in Corea a great disproportion between the numbers of the sexes, the males being the more numerous. There seems to be no evidence of female infanticide, but a greater number of deaths among girls in infancy. As a land of large hats Corea is unsurpassed. At Phyong Yang, a large town on the west coast, the hats worn by the poor women are baskets three and a half feet long, two and a half wide and two and a half deep, which conceal their faces as effectually as does the white cloak which women of a better class wear over their heads. The men wear a somewhat smaller basket of the same shape. It requires both hands to keep it in place. A simi- lar structure, of a size but little larger, is used to cover fishing boats. The monument erected over the grave of a doctor of let- ters is the trunk of a tree painted like a barber’s pole up toa height of some thirty feet. The top and branches are cut off, and on the summit is placed a slim carved dragon twenty feet long, with a head like that of an alligator. Mr. Carles reports, contrary to the statements of some other travelers, frequent evi- dences of mineral wealth. M. de Mailly-Chalon's Fourney— M. de Mailly-Chalon gives in the Bulletin de la Société de Geographie a paper on a journey in Manchuria, from Peking through Kirin to Ninguta, and then along the Tiumen to Vladivostock.

From Vladirostock the travelers _ proceeded to Tomsk, thence to Samarkand, through Karshi to Bokhara, to the Amou-Darya at Charjni, down that river to Petro- Alexandrovsk, thence to Khiva, and lastly across the Kara-Kum to Merv, Sarakhs and Meshed. Oceanica—New Zealand—The April issue of the Proceed- ings of the Royal Geographical Society contains an account of a recent exploration of the King country of the North island, New Zealand. This country, containing some 10,000 square miles, is the Maori stronghold, and white men were, after the war 0 1863-64, forbidden to enter under pain of death. It had thus never been surveyed prior to Mr, Kerry-Nicholl’s expedition in 1883. In the course of 600 miles of travel twenty-five rivers not previously shown upon the maps, and two small lakes, were found ; the sources of the four principal rivers of the colony, the Whanganui, Waikato, Whangaehu and Manganui-a-te-Ao, were traced; the hydrograph y of oe es in relation to the four distinct here flowing into ined ; the or = Mt.

The southern part of the tableland, known as the Rangipo plateau, rises to 3000 feet, while the part near Lake Taupo is about 2000 feet. Tongariro’s active crater is nearly a mile in circuit. Ruapehu is among the largest extinct craters in the world, and is not a cone of scoria like Ton- gariro, but a gigantic crater of elevation with a base sixty miles around. The Kaimauawa mountains are almost in the center of the island, neve — 600 feet, and extend along a base of about eighty m The Wisivicha river, which rises on the eastern side of Rua- pehu, is one of the largest streams in the island, and descends by a series of grand cascades. The waters of the Upper Waikato burst from the sides of Ruapehu very near the Whangaehu, and the streams for a while run parallel, though afterwards they run in opposite directions. The finest forest in New Zealand is that of Te Rangikaika, which covers some 3000 square miles between Ruapehu and the west coast. Mr. Kerry-Nicholls reports that the Maori race is greatly on the decrease. South AMERICA.—Roraima—Particulars of Mr. Im Thurn’s ascent of Roraima, with some illustrations, are given in a recent number of ature. Koraima and Kukenam are separated by a wide gorge, and seem like two fortresses, with walls 1200 to 1800 feet high, built upon a mountain top 7000 feet in height. The north, east and west sides of Roraima are forest-crowned, but on the south and south-west it is for the most part devoid of trees up to 5890 feet. From here to the cliff-face the slope is steeper and covered with thick undergrowth with few large trees. The cliff of Roraima was ascended by following a ledge of rock running from the tree-covered part up to the summit. The botany of the slope was very interesting, but the top itself is covered with an ex- tremely scanty and insignificant vegetation. There are several pools of water, and on all sides are grouped rocks of the strangest and most fantastic forms—portions of the solid sandstone on which they rest. Bushes three to six feet high, a few scrubby orchids, two species of thick-leafed ferns and a variety of the red Utricularia which grows below, ees the botany.

Dawson (Science, April 24) describes the Saskatchewan country or that portion of the prai- ries which extends north of the northern boundary, as containing an approximate area of 300,000 square miles, and as less than 2000 feet above the sea-level, and thus lower than the correspond- ing porso of the continent further south. Parts of this area are characterized by scattered groves of aspen and other trees. The Red River valley has an altitude of 800 feet only, and from this level the surface slopes gradually upward at the rate of four to VOL, XIX—NO. VIII. 52 788. General Notes.

There the horizontal and unaltered strata of the Cretaceous and Laramie formations break against the base of the ancient rocks of the mountains into a series of sharp and nearly parallel flexures. In the central por- tion of the plains are a tumultuously hilly belt known as the Mis- souri Coteau, and also a line of indefinite elevations nearly paral- lel to the Coteau. The most remarkable difference between this region and that west of the Missouri is perhaps the extraordinary abundance of small lakes or “ sloughs,” evidently connected with the mantle of glacial drift. These usually occupy shallow basins without outlet, many are emptied by evaporation before autumn, and others from the same cause become more or less saline. The North and South Saskatchewan, Red Deer, Bow, and Belly rivers rise far back in the Rocky mountains, and while subject to con- fa spring freshets, are generally not in full flood till June or July. The Xingu,— Dr. Clauss recently gave, before the Munich watershed between the Paraguay and the Amazon. This water- shed is 300 to 400 meters high, and is a savannah broken up by forests along the water courses. The watersheds between the tributaries of the Amazons in this region are unknown. Brazilian geographers direct the upper course of the Xingu to the Tapajos, and put the source of the former under 11° S. lat. Eight days after the expedition had crossed the last tributary of the Tapajos they reached a large river which they named the Rio Batovy, and de- scended in bark canoes to the Xingu. The inhabitants of some Bucairi villages were found to be utterly ignorant of metals.

Ameghino, is one of much importance to the history of the Mammalia, and especially to the history of the ampean and recent faunz of the neotropicgl realm. Ever since M. Bravard announced the existence of species of Palzotherium and Anoplotherium in strata within the limits of the Argentine Confederation, the curiosity of palzontologists has been awaiting an explanation of a statement apparently so at variance with the paa facts of the science. M. Ameghino, aided by the labors of Professor Scalabrini, has fortunately resolved this problem, and with it has set before us a record of uncommon interest to the students of the Mammalia and of their evolution. The strata which have yielded the collections studied, are situ- ated on the Parana river. The number of species obtained is. sixty-two, which are referred to forty genera, which are distribu- ted into aiden as follows: Cetacea 3; Carnivora 3; Artiodactyla 2; Perissodactyla 5; Toxodontia 4; Rodentia 11; Edentata 17. Of these forty genera, sixteen also occur in the Pampean fauna. Of these forms it is not to be supposed that all have been fully elucidated and their places finally ascertained. This is especially true of the ungulate orders, where the much-needed determina- genera to families characteristically Pampean, is so highly See ble as to require less exhaustive demonstration to command belief. It is in these groups that the most interesting contribu- A uii Restos de Mamiferos Fósiles Oligocenos Recogidos por el Prof. aad ni y pertenencientes al Museo provincial de la Ciudad del Parana ; por Flor- entino ped ain; Buenos Ayres, 1885, pp. 204.

[ August, tions to the history of the evolution of the well-known Pampzan genera have been made. us a series is traced backwards in time from Toxodon, which shows that in the more ancient types the dentition was less rodent-like, since the molars were shorter and the canines larger. This adds evidence to the opinion which the writer has reached, that rodent-like types are not primitive but derivative! Protypotherium is believed by Ameghino to be the ancestor of Mesotherium. Scalabrintherium stands in the same relation to Macrauchenia. As to the Edentata, the cases of evident ancestral relation are numerous, and are expressed in such names as Promegatherium Amegh., Promylodon Amegh., Palzhoplophorus megh.,and Protoglyptodon Amegh. Perhaps the most interesting fact in this connection is the existence of more or less enamel in bands on the teeth of the gravigrades of this formation, proving that the history of the dentition of the Edentata has been one of degradation, as the writer had already concluded before reading M. Ameghino’s memoir? This fact is confirmatory of the theory of descent of the Edentata from the Tzniodonta, proposed by On THE GAMPSONYCHIDA, AN UNDESCRIBED FAMILY OF FOSSIL Scuizorop Crustacea.!—The opportunity of examining at my leisure about a dozen specimens of Palgocaris typus of Meek and Worthen, kindly afforded me by Messrs. R. D. Lacoe and J. C. Carr, has enabled me to work out some characters of this genus not mentioned by the original describers. The study of these imens has led me to compare the genus with Gampsonyx, and the result has led to the formation of a family or higher group for the two genera, which should probably stand at the base of . _ the Schizopoda, while also serving to bridge over the chasm a ü ie oe 1885, p. 347, for the origin of the Rodentia from the Tillo- “See NATURALIST, 1885, p. 352, and I e 1257. * Report Expl.

Palæocaris was first described by Messrs. Meek and Worthen in the Proceedings of the Academy of Natural Sciences of Phila- delphia, 1865, p. 48, from specimens occurring in claystone nodules in the lower part of the true coal measures, at Mazon creek, Morris, Grundy county, Illinois. Afterwards in the third volume of the Report of the Geological Survey of Illinois, 1868, the same authors figured the fossils and expressed themselves as follows regarding its affinities : “ Hence it would seem to present something of a combination of decapod (macruran) and tetra- decapod characters. That is, it possesses the caudal appendages, anteriorly-directed thoracic legs, the antennze (some of the speci- mens appear also to show basal scales to the outer antennz), and general aspect of a macruran, with the distinct head, divided thorax (without a carapace) and seven pairs of thoracic legs of a tetradecapod. We have not been able to see its eyes, but from its other decapod characters, and its analogy to Gampsonyx, which is said by von Meyer to have pedunculated or, at any rate, movable eyes, we are strongly inclined to believe that our fossil will be found to agree with Gampsonyx in this character also. “Tt therefore becomes a matter of interest to determine to which of the subclasses, decapods or tetradecapods, it really be- longs. That it belongs rather near Gampsonyx, though not to the same subordinate section (Schizopoda), there can be little doubt. Hence these two forms apparently fall naturally into the same family. Professor Jordan and Mr. Meyer seem to have regarded Gampsonyx as a tetradecapod, connected with the Am- phipoda, but also possessing macrural decapod affinities. Profes- sor Dana, however, regards it as a low type of Macrura belong- ing to the section Schizopoda. He and Dr. Stimpson, to whom we sent sketches of our better specimens of Palezocaris, concur in the opinion, judging from all its characters yet known, that it is a low embryonic type of the Macrura, in which the carapace is not developed. s “ Generically it is separated from Gampsonyx, figures of which (cuts Cand D) we have added for comparison, not only in the nature of its caudal appendages, but in the more important char- acter of having its thoracic legs simple, and not bifid as in the- Schizopoda.” | In our specimens we were able to detect well-marked narrow lanceolate oval breeding lamellz on eight pairs of appendages, It should be observed that the breeding lamellz are in part represented in Meek and Worthen’s figure, but not referred to in their description ; they are also partly represented in their copy of Jordan and Mr. Meyer’s figure of Gampsonyx Jimbriatus ; in the latter there is also present what is apparently a large coarsely- spined mandibular palpus, somewhat like that in the male of the existing deep-sea schizopod, Petalophthalmus armatus, described 792 General Notes. [August, by Willemoes-Suhm.’ In the females, however, the palpus is small and unarmed, and it is probable that all my specimens of Palzotypus are females, since most of them have breeding lamel- læ. In the figure of Gampsonyx referred to, the thoracic legs themselves, irrespective of the breeding lamella, are represented as biramous, and the two rami are drawn as of nearly equal length; it is probable that there has been a mistake in drawing the legs, as in none of the existing schizopods, such as Mysis and allies, Euphausia, Gnathophausia, Petalopthalmus or Chalaraspis, are the legs thus thrice divided. It is to be hoped that the fossil itself will be examined anew with regard to this important point. It is sufficiently evident, however, that Gampsonyx and Palzo- caris are closely allied forms, and as suggested by Messrs. Meek and Worthen, should fall into the same family, which may be called Gampsonychide. The principal character which separates this group from all other schizopods is the entire absence of a carapace. t is worthy of notice, however, that the size of the carapace is very variable in the Schizopoda, and in the genus Petalophthal- mus there is a great discrepancy in the two sexes; in the female it covers the entire thorax, while in the male it is remarkably small, subtriangular, leaving the two hinder thoracic segments entirely exposed, as well as the sides of the two segments in front. In the large size and oval-lanceolate shape of the breed- ing lamellz, both of the gnathopods (maxillipedes) and thoracic feet, the Gampsonychidz agree with Petalophthalmus, in which they are large and broad. In the shape of the telson and the comparative size and proportions of the last pair of abdominal appendages there is a close relationship in the Gampsonychide to the schizopod genera Petalophthalmus and Chalaraspis, espe- cially the latter genus, in which the telson is rounded at the end, while the two rami are more as in Petalophthalmus, though broader. The other biramous abdominal appendages in the Gampsonychidz are truly schizopodal. Classifying the Schizopoda by the carapace, there would seem to be three groups, as follows: 1.

But I should agree with Willemoes-Suhm that this is not a natural genealogical classification, and throwing out the Nebalia- dz, which we have endeavored to show belong to a distinct order of Crustacea, the families of schizopods may be enumerated thus, all having seven abdominal segments : carapace ab 6 pairs-of thoracic legs... sser sse sses sess..

GEOLOGICAL News.—Si/urian.—Various studies b Brogger, upon the Silurian strata of Norway and their contained fossils, are published in the Magazin fur Naturvidenskaberne, Christiania, 1878—1882-1884, and furnish new data for a compari- son between the Scandinavian, German and English Silurian. Devonian.—P. Wenjukoff has published (in Russian) a work upon the Devonian strata of European Russia, with a table of comparison with the beds of Belgium and Eifel. It appears that the Russian beds belong to the Middle and Upper Devonian. Carboniferous —MM. B. Renault and E. E. Bertrand have found incontestable proof of the existence of fungi in Carbonifer- ous times. In the tissue of the seed of a conifer of this epo (Spherospermum oblongum) the mycelium of a fungus was found, consisting of threads which were lengthened out or irregularly bunched together, according to the size of the cellules in which they were developed. The cellules of the hypla may be entirely or totally transformed into sporangia, in the latter case the part which touches a sporangium is furnished with a cuticle. Two sporangia are often thus separated by a cuticle cellule. The sporangia are ovoid, are swollen upon the side of the orifice. They are usually empty. The Grilletia are thus remarkable for thei rangia without a neck and without an operculum, and for their habitat in the seeds of gymnosperms. They must be placed near Aphanistis, Catenaria and Ancylistis. The annals of the Belgium Royal Museum of Natural History, 1883, contain the fourth part of De Koninck’s studies of the fauna of the Car- boniferous Limestone of Belgium. This part is devoted to the Gastropods. Among new species are numerous Calyptreide, four of Helminthochiton, four Dentaliidz and a small Hyolithes. Mesozoic.—M. Bleicher (Bull. Soc. Geol. de Fr.) gives a strati- graphical study of the iron beds of Lorraine, belonging to the Upper Lias and Lower Oolite. From a comparison it appears that there is a great agreement between these beds in France and Germany and the corresponding ones in England. M. Neu- meyer (Denksch. d. kais. Acad. Wien, 1883) contributes his views upon climatic zones during the Jurassic and Cretaceous periods.

Quaternary —M.Stanislaus Meunier has described a Quaternary flint from the valley of Loing, forty-five mm. in diameter, con- taining not only a movable nucleus of stone, but a quantity of water. Such cases are well-known among quartz or concretions from amygdaloid rocks, but the example is said by M. Meunier os to be unique among flints. The water must have come from the Quaternary in which the flint, itself of Cretaceous age, was __ lying, and must have penetrated the stone by permeating the silex.

In such compounds the degree of com- cate the mean equivalent weight of its atomic unit, corresponding to an atom of NaCl, for which purpose H,O and CaO are divided mal composition), is (ca.al2.si3) 06; the small letters representing atoms, ando= 8. This gives an equivalent of 107, which di- vided by six yields for the mean atomic weight of the unit in both of these species P = 17,83. Dividing this latter number by 2.7, as the specific gravity of meionite, we have for the atomic volume in this species V = 6.60, and by 3.4, as the specific grav- ity of zoisite, V = 5.24. The true formulas and equivalent weights of these polysilicates must be deduced from a comparison of their specific gravities with those of species whose equivalent weights are otherwise determined. Meanwhile it will be seen that zoisite, with the lower value of V or, in other words, the more condensed ‘Edited by Dr. Geo, H. WILLIAMS, of the Johns Hopkins University, Baltimore. ? Abstract of a paper read before the Nat. Acad.

These, from the frequent impurities of natural silicates, can sel- dom be fixed with exactness, though with sufficient precision to give very nearly the values of P and V, which latter serves to determine the place of the species in the natural system of classi- fication. Water being an element universally distributed, its presence or absence in a silicate becomes of subordinate importance in deter- mining alike the genesis and the natural affinities of species, so that the water-ratios are omitted in the tables of classification (which were shown), wherein the various natural silicates are, from the chemical side, considered with regard to the atomic ratios ot fixed bases to each other and to the silica. There are genetic reasons for separating silicates of sesquioxyd bases, like alumina from protoxyd-silicates. The former of these constitute the class of Persilicates, and the latter the Protosilicates ; those containing both protoxyds and sesquioxyds being designated Protopersili- cates. Ferric oxyd and zirconia are classed with alumina as ses- quioxyds, while titanic and boric oxyds in silicates are counted with the silica in determining the atomic ratios. - In the table of the Protosilicates, and in that of the Persilicates, both hydrous and anhydrous, the generally accepted ratios of the fixed bases to the silica are noted, but in that of the Protoper- silicates regard is had to the more important ratios of sesquioxyds d fixed peroxyds to each other, inasmuch as the ratio of silica to both of these is found to vary greatly in closely related spe- cies, as may be seen in zeolites, feldspars, scapolites and micas. In these tables the three great classes of silicates are each arranged in groups, with primary reference to physical characters. _ Thus for Protosilicates we have in parallel columns, Pectolitoid, Spathoid, Adamantoid and Ophitoid, with each of which the range of values for V is given, while in an adjacent column to the left are inscribed the approximate atomic ratios of fixed pro- toxyds to silica. Among pectolitoids are included with pectolite, apophyllite and datolite, hydrohodonite, pyrosmalite, dioptase, _ calamine, cerite, thorite, etc. The spathoids embrace willemite, tephroite, gadolinite, helvite, leucophanite, wollastonite and tscheff- kinite ; the adamantoids, chondrodite, chrysolite, phenacite, bert- Yandite, hornblende, pyroxene, titanite, and danburite, while the oids include various hydrous silicates, of which villarsite, Serpentine and talc are representatives, __ The Protopersilicates, in like manner, are grouped under the s of Zeolitoid, Spathoid, Adamantoid and Phylloid, a subor- 1885.] Mineralogy and Petrography. 797 dinate division to the latter being designated Pinitoid. In a col- umn to the left are given the atomic ratios of sesquioxyds and fixed peroxyds, the silica being variable. The zeolitoids include besides the zeolites proper, forestite, prehnite, catapleiite, etc. Under the spathoids of this class are placed petalite, all feldspars and feldspathides, including iolite and sodalite, the scapolites, barylite, milarite, gehlenite, sarcolite, melilite, wohlerite an eudialyte. The adamantoids include keilhauite, schorlomite, ilvaite, idocrase, garnet, allanite, beryl, euclase, ardennite, axinite, epidote, zoisite, jadeite, spodumene, sapphirine, staurolite and the various tourmalines. In the phylloids are included the whole of the micas from phlogopite and biotite, through seybertite, chlor- itoid, lepidolite and margarite to damourite and the muscovites, With the phylloids, and near the magnesian micas, come the various chlorites, while parallel with the non-magnesian or mus- covite micas are placed the pinitoids, including besides pinite, or geiseckite, jollyte, fahlunite, bravaisite, cossaite, gimbellite, etc. he Persilicates are all gathered in two columns under the heads of Kaolinoid and Adamantoid, the received ratios of the fixed bases and silica being given in an adjacent column. The kaolinoids include the various hydrous silicates of alumina from the highly basic schrotterite, through kaolinite and halloysite, to to cimolite and smectite. With these are placed chloropal and also pyrophyllite. The adamantoid persilicates include besides dumortierite, fibrolite, cyanite and bucholzite, andalusite, topaz, the zircons and anthosiderite.

If we regard the silicates as constituting a natural order, the three groups already noticed may be called suborders; A. Proto- silicates; B. Protopersilicates; C. Persilicates. The divisions of these designated Pectolitoid, Zeolitoid, Spathoid, Adamantoid, Phylloid, Ophitoid, etc., will constitute tribes. The tribal char- acters of the spathoids and the adamantoids being repeated in the -suborders, we have A. and B. Spathoids and A. B. and C. Ada- mantoids. The subdivisions of these tribes into families, genera and species cannot here be discussed. The genus feldspar, includ- ing anorthite, albite and perhaps iolite, with other genera, some of which are represented respectively by orthoclase, by leucite, and by sodalite, will constitute the family of the feldspathides. The families of the micas and the pyroxenides in like manner will each include several genera, having different values for V. 798 General Notes.

Professor Roland Irving, of Madison, Wis., in charge of the U. S. Geologi- cal Survey of the Archzan rocks of the Northwest, has just issued a most interesting paper on secondary enlargements of mineral fragments in certain rocks.* A large number of observa- tions show the widespread growth of rounded quartz grains by subsequent deposits of silica, which acts as their cement. This phenomenon, which was first described by Sorby and has since received considerable attention from A. A. Young, Irving, and others, plays a most important rôle in the change of sandstones to quartzites. The enlargement in the same manner of feldspar grains by secondary deposits of feldspar substance was recently observed for the first time by Professor C. A. Vanhise, of Madi- son, whose paper’is appended to the present work. The facts i d are illustrated by a large number of excellent colored plates. ~ BOTANY.‘ RANCHING OF PTERIS AQUILINA.—Much has been written on the structure of this well-known fern, but the relation of the fibro-vascular system of the stipe to that of the rhizome does not seem to have been traced. The widely-creeping rhizome A contains at the center two strong bands of sclerenchyma with two fibro-vascular bundles or rows of bundles between them, the whole surrounded by a ring of bundles much as in Fig. 1 B. In branching division occurs on a line crossing both bands of scleren- chyma, setting off to the branch a portion of both central bundles 1 Bull.

If, however, the branch is to be a frond, a connection is soon formed between the two sclerenchyma bands, dividing both bun- dles or rows of bundles between them. The beginning of this connecting band is seen in Fig. 1 B, a section at the base of the stipe just above the point of attachment. When this connection is completed the bundles all lie in one continuous, though dis- torted ring, the enclosed sclerenchyma occupying the place of pith. From this point upward the band of sclerenchyma which lies on the anterior side of the stipe gradually diminishes Fic. 1.—A, outline of a rhizome with base of stipe, 2-2; B, a horizontal section at point a; c, a bundle which divides; C, horizontal section at the point 4, The areas within the dotted lines are sclerenchyma, the others fibro-vascular bundles.

During these changes the front of the stipe becomes nearly flat and the back more convex, as in Fig.1 C. Farther up all the sclerenchyma diminishes, and at the height of a few inches entirely disappears. The bundles, however, retain the same relative position and the pinne are given off right and left in the same manner as the branches of the stem. i In Fig. 1 B the bundle, c, divides and with part of the adjoin- ing sclerenchyma enters the bud between a and 4 Fig.1 A. In feeble plants this bud is suppressed and the branch at the left is uced to a bud, so that the stipe then seems to arise directly from the main axis.—A. A. Crozier, Ann Arbor, Mich. ATTEMPTED HYBRIDIZATION BETWEEN POND-SCUMS OF DIFFER- ENT GENERA.—In the latter part of May of this year, while ex- amining a dish of material containing duckweeds (Lemna poly- rhiza) and various fresh-water algæ collected in Southern Ne- aes ca, I came across a case of attempted hybridization between _ two pond-scums (Zygnemacez) of different genera, which is well _ worth recording. The plants concerned were Spirogyra majus- -~ cula and Mesocarpus scalaris, both rather common pond-scums of _ our ponds and ditches. The normal mode of conjugation in this _ Spirogyra is by means of short lateral branches which unite so as 1885.] Botany. 801 to form free passages between the conjugating cells, and through these the protoplasm passes from the one cell to the other, result- ing in the formation of a resting spore (zygospore). In Meso- carpus the process differs in this that the protoplasm from ` both the conjugating cells passes into the connecting tube and there forms a rest- ing spore is thus inter-filar, while in the former it is intra- ar.

The attempt at fertilization was futile, of course, and so no effort was made to keep the specimen alive. It was preserved in camphorated water and mounted upon a slide for further study and inspection. We have in this case a suggestion of a reciprocal influence exerted by one cell upon another in process of conjugation. It is probably a kind of sensibility to contact—an irritability, as the older vegetable physiologists would have called it. There was cer- tainly a response to some influence on the part of one or other of ese plants in the case before us. It is perhaps impossible to deter- mine which plant took the initiative, whether the tube of Meso- carpus or of Spirogyra was first pushed out, but it is impossible to escape the conclusion that the second tube was pushed out in response to the first. It is possible that the first tube may have originally pushed out towards a filament of its own kind, and be- coming displaced may have continued its growth towards the 802 Genera Notes.

More Poputar Botany.—A recently published little book, “Talks Afield,” by Professor L. H. Bailey, adds another to the short list which this country as yet affords of readable scientific books on plants. We need not repeat here what we have said over and over again as to the duty of scientific men to prepare authoritative books which shall be written in non-technical lan- guage for the great non-scientific public. The author of the book mentioned has recognized this duty, and has given us a most readable as well as accurate volume. Twenty pages or so are given to a popular account of the greater groups of the vegetable kingdom, and then some of the most interesting features of flow- ering plants are taken up, as the flower, the stem, the rose family, the composite family, a peep at the inside, the sexes of plants, cross-fertilization, etc., etc. We quote from pp. 74 and 75, as an example of our author's style: “ The plant through its roots takes in various compounds which are dissolved in water. These compounds contain carbon, hydrogen, oxygen, nitrogen, sulphur, iron, potassium and other materials, The plant takes these solutions in through its roots by a modification of the phenomenon known to physicists as osmose, a sort of soaking-in process. The pressure exerted by the liquid as it comes into the root through this osmotic action forces the ‘sap’ upwards, but the chief cause of its rise is to be found in another fact: the stomata on the under surface of the leaves are open if the weather is clear and moist, and water is constantly evaporating from them. As fast as this evaporation takes place more water is needed. A demand is made upon the cells in the interior of the leaf which contain more water than those near the stomata, and as these interior cells lose some of their water they in turn call upon cells still more distant, and so on until the call is made all through the stem, and to the minute root-hairs which derive their water from the earth. This water does not flow upwards in tubes or cells, but it is soaked up through the thick walls of the wood-cells, and it keeps soaking upwards as fast as evaporation pumps it out through the leaves. The publishers, Messrs. Houghton, Mifflin & Co., of Boston, have given the book a neat dress, and sell it for the reasonable Price of one dollar, i ugust 26th to September 2d).

Botanists who are anxious to add to their collections can do so, and at the same time take a most enjoyable steamboat voyage upon the great lakes. But let us ask here that the botanists do something to redeem the scientific reputation of their profession. It was a noticeable of the two sciences, botany and zoology? Or is it a difference in Let our botanists prepare good thoughtful papers for Section F, and at the same time lay by numerous notelets for the Botan- ical Club, which will have frequent meetings during the associa- tion week. The club is intended to take in the shorter notes and lighter discussions which cannot properly find place in the sec- . tion meetings. 804 General Notes.

He has been assigned the care of the cryptogamic portion of the herbarium, and will devote most of his time to the study of the parasitic fungi, especially those which affect inju- riously the field and garden crops.

Deyo, of Denton, Wayne county, Michigan, specimens of wheat straw which con- tained from five to sixteen larvæ of a four-winged (hymenopter- ous) fly. The portion attacked was usually near a joint, but might be anywhere along the internode, and was found above every joint, though very rarely above the highest one. The im- mediate region of attack was creased and deformed (Fig. 1), though not swollen, and was Z very hard, so that to cut it, : ee except with a very sharp Fic. 1.—Black dots show exit of fly. knife, was difficult. At this portion of the stalk, which was usually from three centimeters (one and a-fifth inch) to five centimeters (two inches) long, the straw was not hollow but solid throughout. By cutting into this deformed straw the yellowish-white larve were found in oval cells. These cells were about four millimeters (.16 of an inch) long. I published an account of this fact in several papers of Michigan and other States (see Country Gentleman, Vol. 49, P- 817) asking for further information. In response to these inqui- ries I received several communications from Wayne and Wash- tenaw counties, Michigan, in both of which the insect worked extensively. So far as I can learn the insect has never been noticed before ; and as the hardened pieces of straw break off in thrashing and come out =— = Iam indebted for many specimens, says the attack was quite general in Washtenaw county, and that the short straws in the grain had been noticed and commented upon by many farmers who had not even mistrusted that insects had anything to do with it, At our Farmers’ Institute held at Plymouth, in January, I _ found hardly a farmer who had not been vexed by the small pieces of straw, yet not one had discovered the cause.

This insect is very different from the Z. tritici (Riley), (first described in the Rural New-Yorker of March 4, 1882), in being much larger, in its black scape in antennz, black mesoscutum, black coxæ, light instead of yellow pronotal spot, the numerous males and the fact that all are winged. These work to the num- ber of from five to fifteen at one place in wheat stems, instead 0 one or two, and the stalk solidifies. The larva has no teeth on its mandibles and only one joint to the tubercle-like antenna. It differs from Z. grande (Riley) but little in size; but in other _ respects the points of difference are much as above. i ea From the old joint-worm of Fitch (Z. hordei Harris) it differs = — in being larger, in having a black scape to antenna, black mouth- ~ parts, and in working in great numbers in a single straw, in caus- _ ing the straw to solidify, in not forming a swelling and in work- _ Ing anywhere on the internodes of the straw. l __ From Z. elymi (French) it differs in being much larger, and the tegs are not so fully fuscous. Z. elymi works in grass, which 1S ably true also of this species, yet they must be quite distinct, ; 1own by sizes. : j Dr. C. V. Riley kindly informs me that he thinks this is Z. ‘ He sya he has specimens from Virginia, right where 1885.] Entomology. 807 the original types were found, some of which have a yellow scape, others a black one. He thinks this is Fitch’s variety “ttct. lat first thought this Hordei, but the fact that Fitch makes no mention of any specimens with other than a yellow scape and yel- low mouth-parts, and inasmuch as Dr. Harris and the late B. D. Walsh, with Fitch’s descriptions before them, say all of Fitch’s varieties are exactly alike except in coloration of legs, added to the fact that of the hundreds of specimens examined by me, not one showed any tendency to vary from black in scape and mouth- parts, while there was considerable variation in the coloration of the legs, led me to believe that my specimens were of a distinct species. | The fact, as Dr. Riley writes me, that so accurate a scientist as Dr. Harris does not speak of the yellow scape and mouth-parts would indicate that zzgrum and ordei were identical. Another entomologist, who has made quite an extensive study of these Isosoma, writes me that he inclines to the opinion that all our Isosoma are only varieties of one species modified by sur- rounding conditions. t will take much observation to clear all this up. As species are only venerable varieties, which by age have been run into the mold of invariability, it really makes no great difference. Prac- tically the matter remains the same in either case. From what we know of related species, and from the fact that all the internodes (spaces between the joints) are attacked, or receive eggs, it is quite certain that the eggs are laid late in May and in June. By September the larve are matured. I foun several pup in the cells of the straw on September 16. I found a few larve in January. It would seem, then, that a few of the insects pass the winter in the larval state, Specimens kept ina warm room all winter commenced to leave the cells in the wheat stalks, as mature insects, on March 22. At that date a male and female appeared. Each succeeding day ever since from two to eight have appeared. From straw kept in a cold room during the winter no flies have appeared until April 20. It is likely that in the common out-door temperature they would not come forth from the pupa state till May. This point can be easily settled in the field the coming season. This and the date and method of lay- ing will have to await determination till the insects can be studied in the field the coming May. The method of oviposition is un- doubtedly much like that of 7. grande and J. tritici, as described Mr. F. M. Webster (see Report Department of Agriculture, 1884, page 383), and Dr. C. V. Riley in the same volume, page If we may judge from the related insects, /sosoma hordei (see Fitch, 7th report, p. 162) or /sosoma tritici (see Forbes, 13th report, State Entomological Illinois, p. 30, and Riley, Report United States Department of Agriculture, 1881-2, p. 183) we 808 General Notes. [August, therefore greatly to be feared that this new pest will become a serious enemy to successful wheat raising, especially as from a large number I have reared but a single parasite, which as yet is undetermined. Even if it becomes very destructive, it is more than probable that parasites will soon attack it, and that, like the joint-worm (/sosoma hordet), it will after a time become powerless to work very serious mischief. The remedies for this evil are very apparent. As the insects are in the straw from the date of cutting till the following May, it becomes very apparent that by cutting the wheat high, in which | case nearly all the insects will remain in the stubble, and then | burning the latter, all these will be destroyed. In case there is | much green vegetation, it would be better to cut the stubble low | before burning. If short pieces of the straw are found in the grain, these should be cleaned out and burned. From experiments made in the laboratory, by burying the straws in sand, and the insects still coming out, I doubt if plowing under will prove a very thorough remedy. As these have good fully-developed wings, rotation of crops would not serve as well to protect against this insect as it would in case of J. tritici and 7. grande. i The drawings were made from life by my special student in a boy P.

Christy exhibited a drawing of the larve of the local form of Platysamia columbia, known as Nokomis; he had found the larva in Canada feeding on Eleag- nus argentea, the peculiar silvery appearance of which was strik- ingly in accord with the color of the larva, which latter was probably protected thereby.

ORGANISMS IN IcE.—Professor Leidy relates that he had placed in his hands for examination, a vial of water obtained from melt- ing ice which is used for cooling drinking water. From time to time, among some sediment taken from a water-cooler, his in- formant had observed what he supposed to be living worms, which he suspected were introduced with the water into the cooler, and not with the ice. Upon melting some of the ice alone, the worms were still observed, and the water submitted for examination was some that was thus obtained. Professor Leidy was surprised to find a number of worms among some flocculent sediment, mainly consisting of vegetal hairs and other débris. Besides the worms, there were also immature Anguillule, and a number of Rotifer vulgaris, all living. It would appear that these animals had all ae contained in the ice, and had been liberated on melting.

A Hermapuropitic Cras.—While conducting an exercise in zodlogy a short time ago using the common crab (Callinectes hastatus) I noticed one specimen having an abdomen intermediate in form between that of the normal male and female specimens. I at once inferred that it might be a case of hermaphroditism, which I think it is. The abdomen is triangular and except the terminal portion or telson is devoid of joints; the joints of the normal female abdomen being represented by indistinct lines. The abdomen was firmly imbedded in the plastron, it being evi- dently not within thé animal’s power to “open” it. dominal appendages resemble in general those of the female, al- though much more attenuated and having an undeveloped appear- ance. The fifth pair of pereiopods lack the reproductive orifice in the basal joint found in the male; nor is the first pair of pleo- pods modified into copulating organs. The two little hooks fastening the abdomen into its groove are present ; while there are only impressions representing the opening through the female plastrons for the expulsion of the eggs. en examined the in- ternal organs were not in condition for a minute examination, still it is evident that neither male nor female organs were normally developed, as these organs were distinct in other specimens in similar condition, while they could not be found in this one.—A.

Tue Mute DEER IN DomesticaTion.—I find here three speci- mens of Cervus macrotis var. californicus in domestication, which _have given me an opportunity of observing them not hitherto en- joyed. This variety of the mule deer I first discovered at Santa Bar- bara in 1875 and spent nearly a week in the mountains and pro- cured specimens for mounting, which I sent to the Smithsonian Institution, and I first described them in The Antelope and Deer of America, p. 95. While they are a true Macrotis, the variety is very distinct, the enormous ear which induced Lewis and Clark, who first discovered them, to call them the mule deer is common ‘to both varieties, but the ear on this new variety I now find is not 812 General Notes. [August, so uniform in size as in the Eastern or mountain variety. Of the three specimens now under observation, one, a male, one year old, has the largest and coarsest ear I ever saw on one of the species of that age, being eight inches in length; while the pair in the adjoining paddock, belonging to Mr. Palmer, are two years old, have ears seven inches in length, which are smaller than the average of the species, though still larger than those of Cervus columbianus, which has the next largest ear for the size of the animal of any of the American deer. In color, too, they are more variable than the mountain variety. The yearling speci- men above described, belonging to Mr. Simmons, is of the dark gray color, so uniform in the mountain variety, from which no one would think of distinguishing it, but for the peculiar coloring of the. tail, which is after all the most distinguishing feature of this variety from the other, and in these specimens is more pro- nounced than on the specimens procured at Santa Barbara. In the mountain variety the entire tail is a yellowish white, except a jet black tuft at the end, while on the California variety ere is a dark line extending on the top or upper side all of the way down to the terminal black tuft. In the Santa Barbara specimens this dark line down the tail was of the color of the coat above, while on these the dark line is black like the terminal tuft—at least this is the case with the yearling buck and the two year old doe, which are evidently of normal color. The two- year-old buck, however, is of a much brighter color than any other Macrotis, which I have seen. While it is not a white deer it approaches the white, the ears being the darkest, or nearest the normal color of any part of the animal. On the tail of this deer the dark line is much obliterated, but not entirely so. That which distinguishes C. macrotis from all other deer is that the under side of the tail is naked to about the same extent as the horse’s tail. This peculiar feature is observed on all of the Specimens of both varieties to the same extent. The habitat of C. macrotis is from the Missouri river to the Pacific limits.—/. D.

The reduction of the smaller toe Albrecht is disposed to ascribe to the wearing of shoes. ZOOLOGICAL News,.—-Celenterates—Mr. S. J. Hickson (Trans. of the Roy. Soc., 1883) describes the ciliated groove which exists upon the ventral side of the stomodzum in many of the Alcy- onarians. This groove, or “siphonoglyphe,” which keeps up the circulation of water whilst the animals are retracted, is not present in the three genera of simple Alcyonaria, assumes more important proportions in these colonial forms (as Alcyonium, Spongodes, etc.), which have long body-cavities, is present in one of the two forms (the siphonozooids) of the dimorphic Alcyonaria Keemia lidæ), and is absent in the Gorgonidæ, in which the solid axis occupies a greater bulk than the sarcosoma. The itho works these facts into a new classification of the order, which he divides into (1) the Proto-alcyonaria, (2) the Stolonifera (Tubipora, Cla- vularia, Sarcodictyon, etc., (3) the Pennatulida, (4) the Gorgonidæ, containing the Primnoaceæ, Gorgonaceæ, and other families with- out a siphonoglyph, (5) the remaining Alcyonarians (Ccelogorgia, Paragorgia, etc., with a siphonoglyph. Echinoderms. — In the Philosophical Transactions of the Royal Society (1884), Mr. Herbert Carpenter describes a new crinoid from the Southern sea. This species, Zkaumatocrinus renovatus, presents two characters found in no other Neocrinoid, but present in some of the older Palzocrinoids. These are the persistence of the oral plates of the larva in the adult, and the separation of the radials by interradial plates. There is also a closed ring of basals on the exterior of the calyx, and a jointed arm-like ap- pendage on the interradial of the anal side. The ex ample was dredged ata depth of 1800 fathoms. Like Eudiocrinus, it has but five arms, and is very small. Crustacea.—Recent notes upon crustacea, by E. J. Miers, pub- lished in the Proc. Zool. Soc., London, include a list of thirteen decapods from the Mauritius, five of them not before recorded, from that island, and one, Callianassa martensii Myer, believed to new to science. Mr. F. Day (Proc. Zool. Soc., 1884) exhibited the skin and skeleton of a female Acanthias vulgaris, the whole of the flesh of had been eaten out by the Isopod, Conilera cylindracea. About twenty examples of this crustacean, some of them one and a quarter inches long, were taken from the remains. Mr. Dunn, of Megavissey, who sent the specimen, remarked that in the summer months these lice are very abundant fifteen to twenty miles from land, generally on soft and sandy bottoms. He had taken one hundred dog-fish at once in a mullet-net, but nearly every one was found to have been eaten ina like manner. They devour a fish in a few hours, and hunt in large shoals. Congers and other 814 General Notes. [August, fish leave when they appear, but occasionally a shoal of bream will come and eat them up. Fishes—In the Proceedings of the National Museum Professor Jordan published a paper which includes notes by Mr. S. B. Meek on the types of North American freshwater fishes, found in the ` museum of the Philadelphia Academy. The latter display some deficiency of due caution, to say nothing of amenity, in dealing with the subject. Confidence in some positive identifications, and also some discoveries of error, will be much weakened by a knowledge of the fact that some of the specimens bear unreliable labels. These were placed upon them by a person employed for the purpose by the “authorities” of the Academy, who was totally ignorant of ichthyology, and not very well acquainted with the English or classical languages. At the time of the taking charge of the collection by this person, many of the specimens had not been distributed into separate bottles, and numerous labels were contained in each bottle. Of course they could not be attached to the correct specimens by the curator in question. Mr. Meek finds that the characters of one of the species were derived from “the shrivelled condition” of the type specimen. It is difficult to imagine where Mr. Meek obtained this information, as the speci- men was in a perfectly fresh state when described several years before Mr. Meek was known as a student of the subject. Batrachians—Mr. G. A. Boulenger (Proc. Zodl. Soc., 1884) describes eight new species of Batrachia from the Solomon islands, including the new genus Ceratobrachus. e greater part of England is free from the croaking of the frog, but a croaking edible frog has for some time been found at several spots in Cambridgeshire and Norfolk. This form, usually thought to have been introduced from France and Belgium, has been shown by M", G. A. Boulenger to be the Italian form, Kava _ esculenta lessone. Forty years ago the typical R. esculenta was _ turned out in great numbers in Norfolk, and examples have re- cently been taken. Though, when the whole Palearctic range 1S considered, it is difficult to keep these forms apart, so far as re- gards England they are quite distinct. Indeed, if the genus Pyxicephalus of many authors is admitted, the form /esson@ would fall into it. There is no authentic record of the introduc- tion of the Italian variety, but it was possibly done by the monks. - Birds—Capt. G. E. Shelley (Proc. Zoöl. Soc., 1884) describes three new species of birds from the Kilimanjaro district, East Africa. These are Muscicapa johnstoni, Nectarinia kilimensis, and Pratincola axillaris. Nectarinia reichenowi (Drepanorhynchus reich- ~ enour Fischer) is described and figured. The specimens came reported to have been seen in May, 1883, at Helmsley, in North- _ east Yorkshire, England, and the female was shot.

F. R. Welden, showed that it is divided into two compartments by a partition extending one inch into a passage internal to the os uterus. The Fallopian tubes are very small. The placenta is exactly intermediate between the completely diffuse one of Moschus, and the complexly cotyledonary apparatus of the sheep, for example, on the other. Each foetus has twenty-two to thirty cotyledons, he lesser koodoo (Strepsiceros imberbis) differs from S. kudu, not only in its smaller size, but in the absence of the fringe of long hair down the neck in front, and in the much more com- pressed spiral of the curvature of the horns. Mr. Holmwood, British Consul at Zanzibar, states that it occurs on the Juba river, exactly under the equator, in groups of three or four. A stuffed example from Somali land is in the British Museum. EMBRYOLOGY." ON THE AVAILABILITY OF EMBRYOLOGICAL CHARACTERS IN THE CLASSIFICATION OF THE CHORDATA.—The development of a me- dian axial cord, differing essentially from cartilage, and which seems to arise from a strand of cells constricted off longitudinally justified by facts. Lankester insists for this reason that the term Vertebrata be abandoned, and that the word Chordata be substi- tuted for the name of the phylum, so as to express a fundamental truth in scientific taxonomy. It has been insisted that embryological data are not available for the purpose of discriminating classes, subclasses, etc., and, . 1 Edited by JoHN A. RYDER, Smithsonian Institution, Washington, D. C. 816 General Notes. {August, ment of certain considerable groups, every addition to that knowledge demonstrates that what has appeared to be excep- tional or in violation of general principles, upon further investi- orms. The Chordata present three well-marked modes of embryonic development consequent mainly upon the manner in which the germinal matter of the egg is related to the vitellus, and upon how much the latter takes part directly in the formation of the embryonic organs, and in what manner the blastula or blasto- phere is directly related to its environment in the course of its development and growth. The direct influence of conditions which induce modifications in a purely mechanical manner is very plainly illustrated in embryological development ; in fact it may be shown that the highest type of development as displayed in - the greatest complexity of the germ or embryo has grown out 0 a simpler condition developing under simpler environing condi- tions. It may thus be shown that even the mode of development the ovum has been modified through adaptation. I.

Cleavage total and equal, as a result of which a blastula is directly developed. The invaginated half of the blastula leads directly to the formation of the intestine. No actinotrichia or embryonic fin-rays developed. These features seem to distinguish the Lep- tocardii, or Haplocyemate forms from the succeeding ones. II. The second great subdivision of the Chordata I will call the Epicyemate subphylum. In this series the embryo never becomes bodily invaginated or so pushed into the blastodermic vesicle as to become invested by up-growing folds of the ecto- blast, but remains attached to the yolk bya stalk or is sessile upon and external to the latter, which may or may not form an integral part of the intestine. This group also embraces forms in which no part of the ectoblast is cast off when the embryo is set free. There is no amnion nor any functional allantois devel- oped, The vessels of the yolk-sack, when developed, are respi- ratory in function. e primitive streak is either comparatively short or wanting. This subdivision answers very nearly to the Ichthyopsida of authors. 1. The lowest division of the Epicyemate series may be called the Ichthyoidea, and brings the Amphibia and Marsipobranchii together. In them the ovum is provided with a zona radiata ; there is no outer albuminous envelope ; the zona is often elastic, and the cavity it encloses may increase with the progress of development, and may be covered externally with an adhesive or gelatinous investment. The cleavage is unequal ; no true blasto- disk is formed ; the germinal and nutritive poles are, however, developing intestine.

Petromyzon. - Much may be said in favor of affiliating the marsipobranchs with the amphibians, but whether the development of Myxine will countenance the foregoing arrangement remains to be rned. It is, however, very certain that the general plan of development of the two preceding series approximates that of Branchiostoma far more closely than the more specialized devel- opment of the Ichthyes. lS RES 1 818 General Notes. [August, 2. The highest major group in the Epicyemate subphylum I will call Ichthyes, as it is the only series in which true fin-rays are developed, and in all of the forms embraced by the term true embryonic fin-rays, or actinotrichia, may be found in the fin-folds of the embryo. The ovum is provided with a zona radiata, but is entirely with- out or has only an inconsiderable albuminous. envelope, rarely with loose granules of proteinaceous matter included between the vitellus and zona; no chalaze; no calcareous shell, though sometimes there may be present in addition an outer tough, the intestinal wall. a. The first subordinate group under Ichthyes is characterized by being ectotrophous, for the reason that the embryo is sessile for only a short time, as it soon becomes folded off from the yolk and raised upon a hollow umbilical stalk, so that the yolk event- ually occupies an apparently extra-abdominal position, or rather it lies in a bulbous extension of the abdominal cavity. This series embraces the Selachians and Holocephali. b. The second subdivision of the Ichthyes is equivalent to the Teleostomi of authors. These, as far as known, are ccelotrophous, that is to say, the embryo is sessile upon the yolk, and is never folded off so as to develop a stalk; the yolk is intra-abdominal and below the intestine and between the latter and the greatly distended somatopleure. 4 The Teleostei, Holostei and Chondrostei belong here, and it will be very surprising if any embryological characters are ever found which will separate the archaic Crossopterygians and Dip- noans from this series. For the characters of the latter we must, 1oWever, await the results of the researches of Mr. Caldwell. 1885.] Fhysiology. 819 amnion or the Reichert’sche deckschicht, Rauber, subzonal meni- brane, Turner, serous envelope, von Baer, and the true amnion, are formed, is cast off at birth or when incubation is completed. A highly vascular allantois is also developed in the majority of the species-of this group, and, as a rule, takes the most important share in the respiratory functions of the embryo, and in the development of the foetal part of the placenta whenever that organ is present.— 3. A. Ryder. [To be continued.) PHYSIOLOGY ®.' PFLÜGER’S “ AVALANCHE THEORY” OF NERVE-CONDUCTION.— M. Vulpian calls attention to the fact that in faradisation of vari- ous motor areas in the cerebral cortex of the dog, the effective strength of current which must be used varies definitely with the region stimulated. The minimal effective strength of current for the muscles of the face is less than that for the muscles of the fore-limb, and still less than for the muscles of the hind-limb. In general the strength of effective current must increase with the length of motor nerve tract. This result is readily explained if we consider that the nervous impulse started in the brain grad- ually diminishes in power as it passes along the motor nerve. But this assumption is in contradiction to the classic “ avalanche theory” of Professor Pflüger, according to which the nerve im- pulse accumulates energy in its progress, so that a certain strength of stimulus applied to a motor nerve produces a stronger con- traction the farther the place excited is removed from the muscle. It is this theory which Vulpian undertakes to test, and concludes with a denial of its adequacy. In Vulpian’s experiments dogs were used and so heavily chlo- ralized as to paralyze the reflex powers of the spinal cord. carefully isolated, without cutting, the external popliteal branch of the sciatic nerve and also the anterior tibial nerve, These nerves are in the dog of about the same thickness.

The electrical currents discovered by Holmgren; 2. The bleaching of the visual purple in the outer segments of the retinal rods ; 3.

[August, layer of the retina; both the latter phenomena were discovered by Boll. But Professor Engelmann, of Utrecht, adds another to the objective disturbances caused by light in the retina, namely, that of movement of the inner segment of the retinal cones. The inner segments of the cones become shorter under the influence of light and longer when the light is removed. The amount of this difference in length owing to illumination varies in different animals. The difference was most marked in the fish and frog. In a fish which was kept eight hours in the dark the inner cone segments, measuring from the mem. lim. ext. to the inner pole of the cone ellipsoid, had a length of about 50; after remaining several hours in diffuse daylight the length of the inner cone segments in the same animal was only about 5#. In preparing the retina for observation the eye-ball was rapidly excised and plunged in 3.5 per cent nitric acid, or for several minutes was warmed to 70°—80° C. in 0.5 per cent salt solution. A frog which has been kept in the dark shows maximal con- traction of the cones after several minutes exposure to diffuse daylight. All parts of the visible spectrum produce the change in question, but the more refrangible rays have apparently most marked influence. It is apparently the inner cone segment itself which is directly affected by the stimulus. The movement of the cones and of the epithelial pigment seems to be under the con- trol of the nervous system; for if an animal which has been kept long enough in the dark to bring about maximal lengthen- ing of the cones and retreat of the pigment, be exposed to light so that only one eye is illuminated, the influence of the light is manifested by both retinas; but if the brain has been previously destroyed, the contraction of the cones and the moving inward of the pigment occur only in the eye which is directly exposed to light. We may, therefore, consider that the movements in ques- tion are reflex actions, and that the optic nerves contain motor fibers for the protoplasm of the cones and of the retinal epithel- ium. Engelmann declares also that light acting directly upon the skin of a frog whose head is kept in the dark, brings about the same retinal changes as does light falling directly upon the eyes.—Phliiger’s Archiv., Bd. 35, S. 498.

For the sympathetic qualities, whose selfishness is diffusive, and includes good will to one or more other persons, somewhat dif- ferent data are necessary. The leading interest in this department is that of sex. The metaphysical condition of love, is a pleasur- able hyperesthesia connected with the mental or actual image of a person of the other sex. The province of ethics, and its appli- cation in law in this matter, is the security of the persons interested in this property, mental and physical. If this hyperzsthetic state were always prominent, because based on sufficient grounds, there would be no necessity for laws in the matter, any more than there is necessity for laws to compel people to retain a fortune ora sound stomach. But in fact this hyperzesthesia sometimes has no sufficient raison d’être in the character of its object. Sometimes the mental powers are unable to retain it long at a time; and some persons have little or no capacity for its metaphysical form. For the protection of people who are highly developed in this respect, laws have been enacted which punish infringements on their rights of property. It is, however, evident that these laws may and do work to the injury of the people they are designed to protect. This is the case, e. g., when persons of great affectional capacity are bound to those of little or no capacity. It is the case where a person of fine general organization is bound to a person of coarse and brutal organization. It is also true where persons of high development of sex affection are otherwise of totally diverse and antagonistic constitutions. Hence divorce laws for the separation of such ill- mated persons have been enacted, and their utility cannot be _ denied. It is not divorce laws which are to be feared, but something which lies deeper; that is the weakening of the metaphysical sex interest, and its subordination to lower or less important interests. Any system of religion, state policy, or social custom, which tends to weaken the force and freedom of conjugal affection, is proba- bly the greatest curse that can befall a country. A principal rea- son why this is true is because the metaphysical sex interest con- stitutes one of the most important stimuli to exertion, and there- fore to development. One of the causes which destroy this primal source of energy and happiness in life, is the prevalence of the idea that the senti- ment of love has no real existence; that it is a deception, or at best a sensation of short duration. Such a view can only be demonstrated in the lives of people in whom the instinct and sen- timent are weak or wanting. For such it is doubtless true; but debarred by natural incapacity. But well-constituted persons frequently adopt the idea on various grounds. The reason why 822 General Notes. [August, such well-constituted persons may entertain such a view, is the failure of the individual to realize his or her ideal in this direc- tion. One principal cause of failure to realize the ideal conjugal state, is constitutional weakness of the sentiment. This may be mental alone, or it may be physical. If the “ grand passion” is to exist, its physical basis must not be destroyed. When the affection is properly developed, it leads to a subordination of many things which would conflict with it. Truth and honor become the basis of permanent confidence between the contracting parties, and everything that is disagreeable to the object of affection will be abandoned, so far as consistent with the necessities of existence, and of honorable conduct to others: When the sex sentiment is not well developed, these ameliorations will not take place. One or both persons will have ground of complaint, and if in the bal- ance of motives either finds it more pleasant to him or herself to be disagreeable to their matrimonial partner than to be agreeable, the term of such persons’ association is likely to come to a speedy end. In the case of personal bearing the male sex is often the sinner, since the more sensitive nature of the woman requires more consideration than the more indifferent constitution of the man. In the matter of rationality of conduct and opinions, the female more frequently errs. One of the causes which tend to weaken the sex sentiment, is want of intellectual sympathy. This is at present a more or less necessary evil, but the development of the intellect is progressing, and will bear rich fruit in the field of the affections. Perhaps the i a 1885.] Psychology. 823 selves, and cannot be overcome by enactment. But in many countries the laws are such as to encourage and increase social evils, if not to produce them. It is satisfactory to know that nature is necessarily more con- servative in this field than in any other, so that pessimism has little ground for assurance. The incapable and the feeble in love have little part in the increase of the race. The irregular, excessive, or abnormal development of the passions have still less chance of propagation. e only cause for regret is the apparent ina- bility of the best intellect to reproduce itself in any abundance. The future of applied science may bring us the remedy for this also—Z. D. Cope 3 TENACITY AND FEROCITY IN THE Raccoon.—Happening lately to pass around the shores of a neighboring pond in my rambles, I noticed a crowd of boys gazing excitedly at one of their com- panions who had mounted a large tree overhanging the water, and was “shinning” his way toward the top of it. Inquiry re- vealed the cause to be a half-grown raccoon, which had taken up its quarters there for the day, seeming much disposed to stay where it was, despite the efforts of the youth to dislodge it; and he, having exhausted every method of persuasion suggested by his fellows, reluctantly descended to the ground, and a bombard- ment of stones then began which, though often well directed, did not budge young Procyon one inch from his comfortable position, One of the spectators then produced a revolver and two rounds were fired by the “best shots” in the crowd, six bullets of the fourteen taking effect in its,body. Terrible as these wounds were afterward found to be, the animal “held the fort” (so to speak) with dogged tenacity, its only efforts being confined to clinging to its chosen position in a fork of the tree. Seeing this, one of the boys started off and in a few minutes returned armed with a rifle. The second shot from this struck one of its fore-feet, pass- ing directly through the ball of it. This wound, trivial when compared with the others, so maddened the poor beast that it tried hard to change its position, but its hindquarters being par- lyzed it was unable to accomplish that feat, so in sheer despera- tion it began to rend the useless member with its teeth, savagely tearing it to pieces and dropping them to the ground, Another sure-flying bullet now sped on its merciful errand, and, struggling fiercely with death, the raccoon relaxed its grasp till one paralyzed foot alone sufficed to support its swinging body beyond the eager reach of its tormentors. And there it hung on, till in its dying efforts to regain the former position, it fell fifty feet to the ground with enough life remaining to justify considerable commotion among the boys while administering the coup-de-grace, This instance brings to mind another which happened during the winter of 1879-80. Whilst a scholar at Westtown, Chester Ps $24 Gereral Notes. [August, county, Pa., I found, during one of my excursions along Chester creek, a half- grown “coon,” which had snugly tucked itself up in the forks of a dead willow that stood on the opposite bank of the stream from me. It had its back to me, and desirous not to spoil the valuable pelt, I drew off some twenty yards and sent a heavy charge of shot into its body ;—such at least was my intent, but, judging of results, I did not accomplish it.

After continuing this long enough to have drowned the liveliest of cats, it reached the opposite shore, and instead of climbing upon it, the maddened creature disappeared beneath it, where a strong eddy of the waters washed and swirled under the overhanging banks and tree-roots.

Burnt Cray 1n THE Mounps.—The earliest travelers among the Indians mention mounds with buildings on the top of them covered with earth. In the mounds which I have examined, wherever burnt clay has been found more or less ashes occur underneath, and the impress of grass, sticks, cane or poles plainly reveals itself in the burnt clay. These vegetable substances were needed to support the earthen roof of the dwelling. The dwellings of some modern Indians are built of poles, sticks and grass, covered thickly with mud. Upon the death of any of the inmates the house is burned down, and the framework = consuming partly bakes the clay and leaves its impress therein. The Pimos and Maricopas of the Gila river, with all of the Indians of the Colorado river, build winter and summer dwellings. The former are hemispherical and mud-covered, the latter is an open mud-covered shed. When these are burned down at death, the clay jis baked and appears just like that dug from many mounds. In many of the modern houses the earth is dug out in the cen- ter for a foot or more; this points to the reason for the pits found in the middle of mounds. Charred posts are found in mounds, the same phenomenon presents itself whenever a summer shed is consumed, In examining the celebrated ruins of adobe and stone houses in Arizona, it is found that they were destroyed by fire, burnt clay with impressions of sticks and poles being found in them. The examination of some mounds demonstrates the existence of buildings without clay covering. Now I have lately visited several Indian tribes who live in the hot season under sheds cov- ered with thatch, with merely earth enough above to keep the . twigs from blowing away. Now the burning down of such a shelter would leave only ashes and c ` Again, both houses are on the outside the receptacle of every- thing which the Indians wish to keep out of harm’s way, baskets, pottery, wattled granaries for corn, mezquit, &c. Now in some mounds I have found the pottery and other relics so curiously located as to leave little doubt in my mind of the burning of such a structure as I have just describe à The modern hut builder does not cover his consumed dwelling with a mound because the new arts taught by the white man and his new environment have taken away all necessity. Further- more the argument that the superior arts of the former Indians were associated with better houses for the artists is false. The finest works of modern art are produced in places no more ele- gant than the Pimo’s summer shed.—Zdward Palmer. 1 Edited by Prof. Ors T. Mason, National Museum, Washington, D.

Putnam, of Davenport, Iowa, has published a pamphlet of thirty-eight pages as a vindication of the authenticity of the elephant pipes and in- scribed tablets in the museum of the Davenport Academy of Natural Sciences, from the accusations of the Bureau of Ethnol- ogy of the Smithsonian Institution. Those who have known the history of Davenport Academy, its struggles and triumphs for the love of pure science, and the extreme caution of its leading mem- bers, regretted that anything should appear in a Government pub- lication reflecting upon their veracity or honesty. Tablets are common enough, being made of slate and other material and - worn to-day by the present Indians of British Columbia and Alaska. So long as they do not contain outlandish and unclassi- _ fiable inscriptions there is nothing mysterious about them. the contrary, the elephant pipes are mysteries. When I try to put the cast which we possess at the museum with something else, there is nothing to put with it. Professor Henry once said to one of his assistants who discovered an unclassifiable speci- men: “That seems to stand out so unsociably that we must call it an ‘ outstanding phenomenon,’ and wait patiently until some- thing else turns up to go with it.” The last word that should fall from the lips of a brother naturalist is.“ fraud.” On the other hand, barring this indiscretion, Henshaw is just what Major Powell says about him. e is a very careful and skillful naturalist. We should hail with delight the accession of all such men to the ranks of archeology because they bring light from every side to bear upon our mysteries. It should not make a particle of difference to any of us whether a pipe is the figure of a crow or of a toucan, so long as we know just what it repre- We may rest assured that for a long time every mystery solved will be accompanied by two quite as inexplicable. But, really, too much account is being made of the matter. Squier and Davis are not overthrown.

Before imbedding cover the end of the cork with a thin layer of celloidin, which is allowed to dry on completely.

If for any reason it is desired to remove the celloidin, a little ether and alcohol will dissolve it from the section almost immediately. For the study of loose parts, where the sections would otherwise fall to pieces or require difficult manipulations, such as the placenta or brain, celloidin may, I think, be safely said to surpass any other material hith- erto employed. For mounting sections with celloidin left on them I have found none of the methods hitherto recommended satisfactory. The essential oils I have tried either dissolve the celloidin like oil of cloves, or cause it to shrink and distort the section like oil of Ber- gamot. After trying various reagents, I have settled upon chlo- roform as the most convenient medium of transfer from alcohol to balsam.

SCIENTIFIC NEWS. —The results of the Hudson’s Bay Expedition, in 1884, under Lieut. Gordon, possess much interest, and Dr. Bell’s report on the geology of the extreme northern shores of Labrador, as well as of Hudson’s strait, contains new matter especially relating to the glaciation of that country. As to the botanical collections made, Prof. Macoun affirms that it shows conclusively the arctic charac- ter of the climate of the straits and that part of Labrador north of Nachvak. Raised beaches, 300-400 feet high, were observed on Hudson’s strait. Ancient stone structures, erected by the Eskimo, were observed, and Dr. Bell observes: “From what I have seen of the situations, which the Eskimo in various places in Hudson’s bay and strait choose for their camps, there appeared to be little doubt that they had lived here when the sea-level was 20 to 30 feet higher than it is at present.” . The observations made shows that the basin of Hudson’s bay may have formed a glacial reservoir, receiving streams of ice from the east, north and north-west and south and south-west. The di- rection of the glaciation on both sides of Hudson’s strait was : d. “That an extensive glacier passed down the strait may be inferred from the smoothed and striated character of the rocks of the lower levels, the outline of the glaciated surfaces pointing to an eastward movement, the composition of the drift, and also from the fact that the long depression of Fox’s channel and the strait runs from the north-westward towards the south- east, and that this great channel or submerged valley deepens as _ it goes, terminating in the Atlantic ocean. Glaciers are said to _ exist on the shores of Fox’s channel and they may send down the __ flat-topped icebergs which float eastward through the lower part _ of Hudson's strait into the Atlantic. During the drift period, the glacier of the bed of Hudson’s strait was probably joined by a contribution from the ice which appears to have occupied the site of Hudson’s bay, and by another also from the southward, coming down the valley of the Koksok river, and its continuation 1885.] Proceedings of Scientific Societies. 833 in the bottom of Ungava bay.

Gordon, R. N., left Halifax, May 30, Dr. Bell being the scientist of the expedition. Stores sufficient for more than a year will be taken to provide against any emergency. The round trip is expected to occupy five months. The stations to be visited are Port Burwell, near Cape Chidleigh, Ashe inlet, near North bluff, Stupart’s bay, near the Prince of Wales Foreland, Notting- ham island, Digges island and Nachvak bay, all of which were founded last year. These stations will all be continued, except the last named, which will be dispensed with on the score of economy. Lieut. Gordon expected to reach Hudson’s strait by June 10. Provisions for the ensuing year and eighteen tons of hard coal will be left at each station. A large quantity of evapo- rated vegetables will be taken to the stations. Forty applica- tions have been made for positions as observatory men. Much valuable information is expected to be gained from the observa- tions made during the past year as to the formation and breaking up of the ice and in regard to its movements, also relative to the navigation of the strait. After leaving Fort Churchill, a running survey will be made on such portions of the eastern shore of the bay as are practicable. The A/ert is expected to arrive back in the strait about August 25, and the remainder of the time will be occu- pied in surveying as much of the coast of the strait as is possible. PROCEEDINGS OF SCIENTIFIC SOCIETIES. PHILADELPHIA ACADEMY OF NATURAL Sciences, March 24.— Mr. Garrison communicated the results of his examination of. slag from an iron furnace. Mr. A. H. Smith and Mr. Edw. Potts described borings in the vicinity. One in Cumberland county, N. J., reached a depth of 650 feet, and at 570 feet passed through a bed of oyster shells, stated by Professor Heilprin to be almost certainly Cretaceous. Dr. Leidy spoke upon the giant extinct sloths, and stated that among fossils received last year from New Iberia, La., were three teeth, a close study of which indicated that the form described by Owen as Mylodon harlani should be returned to the genus Orycterotherium, in which it had been placed by its discoverer, Harlan arlan. : Mr. Eastlake presented Entomologia Hongkongensis, and Mr. A.

He also referred to modifications in the tarsal joints of the Silphidz, described in a paper by a Belgian entomologist. The number of joints in tarsi and antennz under- went gradual reduction, but the speaker considered that in view of the intermediate conditions it was ill-advised to give impor- tance to the presence of the smaller number of segments. Professor Heilprin believed that in Paleozoic times no such zoological zones as now occur existed. For instance, no exist- ing Brachiopoda are cosmopolitan, while those of ancient times: were much more widely distributed. The presence of corals, graptolites, etc., in widely separated regions, indicated the former presence of a temperature much more uniform than the present. The speaker then drew attention to points which seemed to invali- date the opposite conclusions arrived at by Professors Neumeyer and Roemer. Though not a single New Jersey species of the present day is found in the Gulf of Mexico, fifty or sixty species of fossils out of 150 from the northern locality are found in Mis- sissippi and Alabama, while only ten out of 200 fossil Texan rms are found in Mississippi, showing conclusively that climate was not the former cause of distribution, These zones were gradually established during some period of the Tertiary. Refer- ring to the pebbles obtained by Mr. A. H. Smith from a boring of 170 feet on Black’s island, Professor Heilprin stated that they came from a glacial gravel, probably the Trenton. The boring had now, at a depth of 195 feet, reached a bed of plastic clay. A paper entitled, Remarks on Lanius robustus Baird, by Leon- hard Stejneger, was presented.

THE REPUTATION OF THE LANTERN FLY. BY JOHN C. BRANNER, N nearly every part of Brazil one may hear the most incredible stories of a deadly insect, the very name of which inspires the greatest awe. When I first heard these stories of the terrible gitiranabota, tiranaboia, etc., as it is called, I was naturally rather skeptical, but continually lisanin them repeated and testified to, not only by the common people but even by men of education and standing, and seeing in print accounts of the devastation wrought by this insect, I was finally induced to inquire into its existence and character. _ To give an idea of the popular opinion of the gitiranaġóta, I need only give a few specimens of the stories that are told of it. The prevailing opinion is, that it is about the size of our seventeen- year locust or a little larger, having a long poisonous beak pro- jecting from its large head; that it has great powers of flight, and when, in its wild career, it strikes any living object—if an animal, no matter how large or powerful—it falls dead upon the spot; if a tree it soon wilts and dies. A certain distinguished Brazilian engineer corroborated the general truth of these stories, and assured me that along the Amazonas a monkey might sometimes be seen among the top- most branches of a lofty tree, when all of a sudden he would come tumbling down dead, without any apparent cause, struck by the fatal gittranaboia. An extract from a Spanish American news- paper was shown me a couple of years ago in which this insect was spoken of as destroying the cattle of Brazil in the grazing country of the southern provinces. In Para I was assured that VOL, XIX.—NO, IX 55 836 The Reputation of the Lantern Fly. [September, it was known to have stung a child which died a few days after- wards in great agony, and in spite of all the physicians could do. Many such cases were mentioned to me in various parts of the empire, and although on several occasions I met persons who claimed to have seen the insect itself, I was never able to come upon an actual case of injury done by the insect, or to see any one who had seen it wound the offended party. Search for the gitiranabéia itself was nigh proving futile also, but by dint of perseverance, cross-examinations, the sifting and patching together of evidence, I succeeded finally in cornering this destroyer of life in general and of the human race in par- ticular. Some of my informants told me that it folded its long beak beneath its body when it was not angry OF bent upon destruction, Here, perhaps, was one character. Others said that its head was very large in proportion to the rest of its body, in size and general form much resembling a peanut. Others again told of its being blind, though it appeared to have large eyes on the sides of its big, ugly head, while others added that this head was luminous, These characters pointed plainly to the Julgore or porte-lanterne of the French entomologists. Before trying to clear its character I took pains to assure my- self that the Fulgora lanternaria is the so-called gitiranabdia, and that it is generally supposed by the common people of Brazil.to be poisonous. Just here trouble began again, for once I could show that this insect was neither luminous nor harmful, it would be stoutly declared that “in that case this was not the true giti- ranabvia.” And this is exactly what happened.’ : Along the coast south of Bahia? the gitiranabota is called the bicho do pau parahy'ba, because it frequents the tree there known as the pau parahy'ba (Simaba versicolor St. Hilaire). . On one occasion a living specimen was taken to Bahia as a great curiosity, and exhibited on exchange, where it was looked ‘upon and treated with the greatest respect. Dr. Antonio de _ Lacerda, a Brazilian gentleman who takes an active and intelli- gent interest in entomology, saw the specimen and heard the - countryman’s story of the death of a person caused by this very e reputation _ — lI hada very similar experience in Brazil with a certain snake, Th _ Of the salamandro was, if anything, a little worse than that of the gitiranaboia, but n the snake was found, and I showed that its bite was not fatal, or even very nful, I was told : “ Then that is not the genuine salamandro.” ; Specimens of these insects can be had of dealers in Bahia for about 30 cents each. “ 1885.] The Reputation of the Lantern Fly, 837 insect. He laughed at the seriousness with which the story was received, refused to believe that it had injured any one, and to the horror of every one present, took the insect in his hand and repeatedly thrust his finger against the point of its beak which was said to be so deadly. I mention this case especially to show that there can be no doubt about the identity of the insect. Dr. Lacerda also showed me specimens of it in his own collection. Another proof of its identity is given by Pompeo de Souza in his Ensaio Estatistico da Provincia do Ceara, p. 216. Among the insects of that province he mentions the tiranaboia, which, he Says, “is supposed to be poisonous, but there is no fact to justify this story.” A dried specimen was sent him from the interior, and he declares it to be a hemipter. Fulgora lanternaria. Natural size. It goes without saying that this gitiranabdia is perfectly harm- less. It may be added also that its scientific name is a misnomer as far as it relates to its producing light. I was often assured that its head was luminous, but I have never met a single person who claimed to have seen this luminosity. Snr. Luiz A. A. de Carvalho, Jr., of Rio de Janeiro, who has several species of these beautiful insects in his collection, assured me that he knew of no evidence whatever that they produced light. Prince Maximilien de Wied-Neuwied says on this subject: “ Nous n’avons jamais aperçu le moindre vestige de la luerer éclatante du fulgore porte- lanterne (Fulgora lanternaria) quoique nous avons souvent pris cet insecte sur les arbres.” 838 The Age of Forest Trees. [ September, Instances of extravagant stories of this kind are not uncommon in Brazil. The case of the sa/amandro already referred to is a good example. Another is that of a plant, a species of smilax, which is said to grow from the dead body of a Cicada. Belief in this story is so general that through some parts of the country a certain plant is popularly known as the japecanga da cigarra, or cicada smilax. Those who claimed to have actually seen this phenomenon represented that the plants seen by them were all quite young. Doubtless they were cases of larve killed by para- sitic fungoid growth.' Such stories come, of course, from imperfect observation, and have an air of truth about them derived from their association with known objects or facts. NoTE.—We are unable to find any reference in entomological works as to the poisonous nature of this insect, which is undoubtedly perfectly harmless. It is, however, disputed whether the insect is luminous or not. See Westwood’s Intro- duction to the Modern Classification of Insects, 11, 428, where after referring to his figure of the head of Fulgora lanternaria, he says it “is the part of the body asserted bel various writers to emit a strong light by Jae analogous to that of the PrE The account of the luminosity of this insect originated with Madam erian, but it:was denied by Olivier, in which opinion Hoffmansegg, the Prince Von DERM and Lacordaire concurred. “ M. Wesmael has recently reasserted the lumi- nous property.of the South American species on the authority of a friend who had wit- nessed it alive. And W. Baird, Esq., has informed me of the existence of a Chinese edict against young ladies keeping lantern flies.” In our Guide to the study of In- sects (p. tay is the following statement regarding the East African lantern fly : “Mr. Caleb Cooke, of Salem, who resided several years in Zanzibar, Africa, in- forms me tal the lantern fly is said by the natives to be luminous.

Speaking of the plant, he says 3.4 : r e co bleues, p. 107. " ; # 1885.] The Age of Forest Trees. 839 One ring is formed each year between the bark and the pre- viously-formed wood. If there is a large healthy top of branches, these concentric rings will be relatively large, especially so if the tree is not overshadowed by older and larger ones. During the past fifteen years there have been thousands of white oak trees sawed down in this. country (Western Indiana) for staves, and I have taken the time and trouble to count the ages of several hundred of them; also the ages of other forest trees; but my observations of the oaks have exceeded those of all other kinds. I was led into this investigation by reading an article in a news- paper purporting to be copied from some scientific magazine, the name of which I have forgotten, which article claimed, not only confidently but positively, that the large rings of growth indicated past wet years in Kansas, or years favorable to vegetation, and. that the small rings indicated past dry years, or years unfavorable to vegetable growth. The article stated that the count from the outside ring inwardly coincided with the past seasons historically as far back as the whites or Indians had any tradition of the sea- sons. The article further stated that some English scientific journal had published an article by some traveler up the Nile, in Egypt, who had made the same discovery there. He had counted the rings on the oak stumps there from the outside inwardly, comparing them with the years counted backwards, and had made the startling discovery that the seven years of plenty followed by the seven years of famine during Joseph’s rule in Egypt, were actually and accurately registered on the stumps. Sometimes an absurdity is so plain that nobody sees it at all. This is one of that sort. It did not then occur to me that a tree old enough to keep books in Joseph’s time would, if living now, be about twenty-five feet in diameter, if it grew like an average Hoosier oak. But the story had a charm for the credulous, and it led me to estimate the age of trees here, and to compare the large and small rings with the years of plenty and the years of famine. To my Surprise, and considerable disappointment, there was no coinci- dence whatever between them. I found stumps of trees of the same species, the same size (and presumably the same age) stand- ing within twenty feet of each other, on the same kind of soil, cut down the same year, and, so far as I could judge, subject to the same conditions throughout, one showing a large ring where its neighbor would show only an average one, and in some few 840 The Age of Forest Trees. [September, ' cases they showed the opposite—one large and the other small, I examined enough to prove that whatever they might show in Kansas or in Egypt, they showed nothing of the kind in Western Indiana. I have not been, so far, able to account for the spasmodic pro- duction of single rings of large or small growth, interspersed here and there among those of the average size. But whena succession of large, and especially small, rings prevail, say from ten to seventy-five or more, I can see a possible cause producing them, and have strong circumstantial evidence that such is the very probable cause of the large or small rings. Trees are like men in some respects. More are born than can live; more live than thrive ; more thrive than can be masters. “ The young cannot hold sway Till the old are dead and out of the way.” The tree that falls behind its fellows in the race of life will very likely fall behind the more active of the next generation also. Many are crowded and smothered out in infancy by their more vigorous brother infants. Nature is not generous or charitable. She knows but one law of growth: “To him that hath, shall be given; to him that hath not, the little he hath shall be taken away.” When a tree gets but little the start of its immediate fel- lows, all the nourishment of nature seems to be offered to it, in- stead of its more needy neighbors. And to the weakest, nature gives next to no sympathy at all. I have seen two trees of the same species, the same age toa year, standing side by side, the one three times the diameter of the other and more than twelve times the solid contents counting increased length. Both were equally healthy, but the smaller had long ago been beaten for the nomination to leadership in convention, and had dropped back among and remained one of the mere constituents. The first rays of the morning’s sun fell on the larger tree. The smaller one had to wait till eleven o’clock for sunshine, and was cut off at 2 P. M., while the larger one received it till sundown. If there was only a small shower the larger one got it. The smaller one got no rain except from heavy showers which leaked through the _ top of the larger one. In such a case the larger tree would have __ large concentric rings, while the smaller one would have them so fine they could be counted only under a magnifying glass. I _ have often seen just such cases. i 1885.] The Age of Forest Trees. 841 ' I have been a civil engineer and land surveyor since 1867, and as such have had occasion to examine many trees referred to in the field notes. The United States surveyed the land into sections of one mile square each, and drove stakes at the section corners, and also at the quarter section corners equidistant be- tween the section corners. They also blazed two trees near these corners about one anda half feet above the ground, cutting a small notch in the blaze, and gave in the field notes the size and species of the trees marked, and their courses and distances from the corners. About fifty years had elapsed between the date of the survey and my day as a surveyor. Many of these trees could be identi- fied at sight by the scar where the blaze was made. In other cases the tree would be so much larger than the size given in the field notes that the blaze would be obliterated by the spread of the bark, and the doubt would have to be settled by chopping into it at the place indicated by the notes. If we found the blaze and notch, we next counted the rings from the outside into the blaze. If the count of rings tallied with the date of the survey— all well. Mark a new tree and record it in what we call the sub- sequent field notes. In the year 1868 or 1869 I was making a survey in the eastern part of the county. Ata certain corner wanted, the field notes called for an ash three inches in diameter. The only ash near and answering to the locality, was about eighteen inches in diam- eter. Nobody expected to find so large a tree in the fifty years that had elapsed since it was marked. But on chopping into it we found the blaze and notch near the heart, revealing the un- mistakable fact that it was the real “ witness tree,” and that it had been marked by a left-handed chopper with a dull axe. A look at the ground and timber about the corner showed the further fact that just before the original (United States) survey was made, atornado had passed over that place and blown down all the adult trees, as all the present ones were young and thrifty, and the graves of the fallen trees were as plain as any mark could be. A tree-grave is easily known; as the tree falls the roots hold a considerable quantity of earth in their grasp, which leaves a large hole in the ground under where the tree stood. In time the body and roots will rot, leaving the dirt piled up on the side of the hole the tree fell on, and it looks as if a grave had been dug with 842 The Age of Forest Trees. [September, the dirt all cast out on one side, and the corpse had got away and the grave remained unfilled. This tree had increased six times its diameter, and more than thirty-six (and counting the increased length nearly seventy-two) times its solid contents since the gov- ernment surveyors had marked it. The next year I made a survey in the rough hills of Sugar creek in the north-east part of the county, and in identifying a land corner I had occasion to examine another ash described in the field notes as three inches in diameter also. It stood on the point of a sandstone ridge, between three large white oaks, which formed a triangle around it, and were about fifteen feet apart. This ash, the same species as the one before described, had not grown to exceed one-half inch in the increase of its diameter in the fifty or fifty-one years since it had been marked. This would allow only one-fourth of an inch on each side; yet I counted under a magnifier, in this small space, the required number of rings of growth, They were thinner than common book paper, as they were at the rate of two hundred to the inch. This tree had increased only thirty-six per cent in fifty years, while the former had increased about seven thousand per cent in the same time. Why this difference in the size of these two ash trees? The reasons are plain. The former had a good soil on level ground, and the tornado had destroyed all the adult trees that would rob it of sunshine, rain and soil nourishment. The latter stood in dissolved sandstone for soil, on the top of a narrow ridge between three large oaks, which robbed it of sunlight and rain, and nearly all the soil nourishment. It had but five or six small branches for a top, and but few leaves to the branch, Under such conditions it did well to even exist. But to do this it was obliged to add a ring each year. - Eleven years ago I examined the stumps of two white oaks and the grave of a third, which told this singular story by circum- stantial evidence so strong that it could not be doubted. In the — year 1502 an acorn fell about one and a half miles from where I am now writing (Rockville, Indiana), and by favorable chance sprouted and grew into an oak. In 1594 another acorn sprouted about twenty feet distant from it. It may “have grown on the tree before mentioned, as it was then ninety-two years old. In 1731 a tornado from the north-west blew down a still older oak, which its fall struck against and greatly damaged the top of the one * 1885. ] The Age of Forest Trees. 843 born in 1502. There is to-day the well-marked grave of the fallen giant, the dirt piled upon the south-east side of the hole, and a long depression in the ground where the trunk fell and rotted till not a vestige of its wood can be seen to-day (though some traces of the bark of the roots can). This depression points to the stump of the damaged oak. The two younger had been freshly cut down when I examined them, Their stumps were about four feet across, and there was not over an inch difference between their diameters, though ninety-two years difference in their ages. The younger had a large, healthy top, no broken or dead limbs, and it had put on rings of growth from the beginning of more than average size. The older one had been injured in its branches by the fall of the still older one before mentioned (in 1731) and for fifty-seven years had put on very small rings of growth (about twenty-five to thirty years to the inch instead of twelve to fifteen as it should), when a new set of branches devel- oped to take the place of the damaged ones, and the rings began to increase in size and gradually attained to the average. I ex- amined their tops, which coincided with what has gone before, There were the peculiar knots in the top of the older one where dead limbs had rotted off and were healed over. (Any expert timberman will readily recognize them.) During this delay the younger oak caught up with the older one in size. The size of a tree is a very uncertain indication of its age. In all the cases of the hundreds I have examined of the oaks (the oldest trees of the forest I think), I never saw but one that was here when Columbus discovered America. That one was by Aar the largest I ever saw, and was over six hundred years old, about twice the age of the other largest ones. I could not get its exact age as it was so decayed near the heart I could not dis- tinguish the rings. It was between six and seven feet in diame- ter, and forked about sixty feet up, and each fork was as large as the other largest trees. It was not sound enough to make good _ lumber, being what in this region is called “ doughty,” a state be- tween soundness and rottenness. It had been down a year before I examined it (being out of the county when it was cut), so that it was very difficult to examine it. I have mislaid my memo- randum of it, but it would be about as follows: At the age of about two hundred years it had some ill-fortune which caused it to form about one hundred small rings. It then regained its 844 The Age of Forest Trees. [September, health and formed normal rings for about one hundred and forty years, when another mishap caused small rings till within the last fifty years, when it was putting on fair growths again. This tree was about one and a half miles south-east of Rockville, Indiana, and was noted among hunters and woodmen. It was a disagree- able showery day when I examined it, and for that reason I did not examine its top to see if dead and lost and healed-over limbs coincided with the small rings, but I have often done so in other cases, and found them to coincide. Last May (1884) I examined a sycamore and water elm in the Wabash river bottom, the former six feet in diameter and the lat- ter five, each one hundred and eighty years old. They stood about one hundred and fifty feet apart. They were stand- ing on the upper end of a newly made bottom (I mean new as compared with the higher and older bottoms a little more inland from the river, say two hundred years old). This was the largest sycamore I ever saw that was sound to the heart. I have seen hollow ones nearly eight feet in diameter. This tree seems never to have met with any mishap till the log man came along, as the rings of growth were all unusually large. 3 These trees very probably sprouted twelve to fifteen feet below the present surface of the bottom. They generally begin life on the lower end of river sandbars, and as sedimentation builds up the surface, they put out new surface roots at every two to three feet of elevation. Such trees with their several sets of surface roots, are often seen in drift piles, and also still standing on the verge of a steep river bank where one side is exposed by the erosion of the river. Their roots are often hollow like their trunks, the hollow (and root too) decreasing in diameter down- ward till it terminates in a point, like a cone standing on its point. In the south-west corner of this county is a hollow cot- tonwood stump on what is now a high bottom of the Wabash, in which the hollow extends downward twelve feet. Mr. Joseph J. Daniels, an intelligent, observing man, on whose land it stands, told meso. Such silting up over the surface roots would kill = most of the upland trees, or those that grow from the seed on the high bottoms. | 1885. ] The Relations of Mind and Matter. 845 THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. (Continued from p. 767, August number.) IV. THE INSTRUMENTALITY OF THE BRAIN. WE have, in the preceding sections, reached several conclu- sions as to the character, development and mode of opera- tion of the nervous organism. We have next to consider this organism in its relation to the development of the mind. This is undoubtedly the most difficult of the whole broad scope of prob- lems to which science has addressed itself. Much has been writ- ten upon it, but we can scarcely say much that is satisfactory. It remains yet in great measure an open question, though a far nar- rower one than of old. Science has strongly attacked the out- works, if not the citadel of the problem, and has effectually dis- persed the cloud of immaterial existences about which the thoughts of men so long hovered. It is becoming clearly evident that all existence is based upon substance. It may not be that species of substance which we call matter. For all we know there may be many species of substance. Yet there is no resting- point between something and nothing, and immateriality sinks into the category of nothingness. But we are able to bring the conditions of the mind much nearer to the ordinary conditions of the material universe than this. The old idea that the soul is brought full fledged from some distant - limbo of souls, and implanted in the infantile organism, might serve for the philosophers of a medizval dreamland, but can hardly be sustained in this wide-awake age. To us the germ of the mental organism forms part of the physical germ, and the whole development of the mind takes place through the influences acting upon the body. It is well known that the degree of the mental development is in close accordance with the variety and quantity of these external influences. If the body be closed against their entrance, through loss of the organs of the higher Senses, the mind remains undeveloped. If all the senses were shut off and no external influence permitted to reach the germ of the mind, it must continue in the germinal state. In like manner if the senses be active, but the brain, the inner organ of the mind, be inactive or abnormal in condition, the mental development is similarly checked. All this needs no argument. Every one 846 The Relations of Mind and Matter. (September, must admit that the development of the mind takes place through the agency of external energies transmitted by the nervous mechanism. But these energies are entirely motor. They are either radiant vibrations emanating from some distant substance, or the motions of molecules impressed upon the body through direct contact. Each of them has its special character, but they are all motions. In their transmission inward over the nerve fibers they continue to be motor agencies. They are now some mode of radiant energy. Those that pass through the ganglia and reach the muscles, prove their motor character by disturbing the motor relations of the muscle cells. Those that are retained in the ganglia, and yield other effects, must do so as motor agencies. It is simply impossible that motion can become anything else. Nor can it exist independent of substance. Nor can it cease to exist. Every quantity of motion must of absolute necessity continue to exist as the same quantity of motion. It cannot lose or gain quantity, or change into some condition that is non-motion. Nor can it exist as an immaterial condition. It is indissolubly wedded to substance. These conclusions can scarcely be questioned by any scientist, yet they lead to certain important inferences, If the develop- ment of the mind takes place solely through the influence of special motions, conveyed to it over the channel of the nerves, then the mind must necessarily be based in substance, and its energies must necessarily be motor. The idea that an immateri- ality can be organized by motor agencies is a mere metaphysical phantasm. But though a definite quantity of motion cannot lose or gain, its action upon matter may be almost infinitely varied. It may separate and become widely diffused, or it may become definitely fixed in a certain aggregate of matter. The organization of mat- _ter takes place solely through the influences of its inherent mo- = tions. The concentration of a crystal may be due to attraction, = but its peculiar characteristics are undoubtedly due to the special = motions of its particles. And an Amceba is superior in organi- zation to a crystal solely through the vastly greater complexity and intricacy of the motions which affect its particles. In all these cases of aggregation the attractive agency seems to be sin- riri in character. Its full effect is resisted by the 1885.] The Relations of Mind and Matter. 847 motion of the constituent particles, and with every variation in the vigor or complexity of these motions some variation in the volume, form or rigidity of the mass takes place. The reduced rigidity and varied constitution of organic cells is primarily due to the great absorption of heat or motor energy in the formation of their chemical molecules, and the variety of such molecules which enters into their constitution. This consideration of the relations of matter and motion leads toa second. Motion may affect matter in either a general or a special mode. In the former case it tends to disorganize, in the latter to organize matter. Heat motion is a disorganizing influ- ence. It constantly tends towards the disaggregation of matter. Electricity yields results partly of disintegration, partly of inte- gration. Magnetism is a more specialized motor agency, and its effects tend to integration. The motor energies which enter into - chemical phenomena are yet more varied and specialized, and tend strictly towards material organization. Thus the disorgani- zation and organization of matter seem alike due to motor agen- cies. In the case of all organization the attractive affinities ot chemical particles enter as an essential element. Motion, of what- ever kind, may oppose these affinities, but it is quite possible for a definite harmony to exist between these two agencies, For in- stance, the solar system is a definite organism, due to the har- monized relations of its motions with its gravitative attractions. The same is the case with the earth as a whole, and with every crystal upon the earth. In the case of the solar system the dis- rupting activity of motion is overcome by its being forced into closed curves of rotation, yielding a fixed balance of energy be- tween the two opposing forces. Something similar may exist in all organized masses. Every mass of fixed organization, whether it be earth, crystal, organic cell or animal body is subject to the opposite influences above named, those of attraction and motion, and its fixity indicates that a definite balance exists between these influences. Motion, therefore, may be said to be organizing when, by moving in closed curves or in other special modes, it becomes in harmony with attraction, the degree of concentration of mat- ter depending on the comparative vigor of the two opposing forces. All this may seem to have no relation to the problem of the development of the mind. Yet it is evident that motion is the 848 The Relations of Mind and Matter. (September, agent directly concerned in this development, and we can conceive of but one result of the agency of motion, that of change in the space relations of matter. The motion which enters the cerebral ganglion, and is retained there, cannot cease to exist. One of two things must happen. It may flow into the surrounding matter as heat, or in some other general and dissipating condition. Or it may become an organizing agent, and enter-into some substance as a permanent factor. It may produce a mental compound of substance analogous to the inorganic crystal, and like the latter unchanging in -form and in its internal conditions, The disorganizing energies of nature act upon the crystal. Heat and electricity pass through it but do not disintegrate it unless they become of excessive vigor. The same may be the case with the mental organism. This much we know, that the special motor energies which enter the body and are conveyed to the cerebrum produce those conditions which we call memories, and which are permanent and unchang- ing. If these are motor conditions they must be motions of organization, influences which partly overcome but which fall into harmonious relations with the force of attraction and con- densation. And it follows as a corollary that the development of the mental organism from its germ to its highest unfoldment takes place through a continued succession of these organizing motor influences. The intricacy of the organism steadily in- creases, as it is affected by motions of higher complexity, but every motor state produced is permanent. The existence of higher motor conditions does not cause obliteration of the lower ones, This is one of the marked characteristics of motion. In the circle the straight line of motion is masked, not obliterated. In the spiral the circle persists. In the spiral vortex all these inferior stages can be traced. And in the organizing motions of the mind all inferior stages persist as constituent parts of the _ superior stages. Consciousness may be directed to any of these motor conditions, in which case they appear as memories. But consciousness has no bearing upon their existence. They con- tinue thfough life active conditions of the mind, though they may seldom or never come within the sphere of consciousness. The preceding argument is not advanced as anything new. It is rapidly becoming a common belief with scientists that the mind has its basis in matter, and that thought is a motor affec- 1885. ] The Relations of Mind and Matter. 849 tion of this matter. The belief in the material basis of mind, indeed, has become a somewhat developed idea. It has of late years grown a more and more widely accepted opinion with scien- tists that the brain is the organ of mind, that mental conditions _ are motor affections of the matter of the brain, and that they can persist only during the persistence of the brain as a functional organ, and must return into the realm of unspecialized motions on the disintegration of the brain. Before considering this ques- tion it was necessary to obtain some idea of the general princi- ples of relation between matter and motion, and of the conditions under which alone motion could be retained in a local mass of matter in a persistent and specialized phase. In addition to a widely entertained opinion among scientists upon this subject, several authors have made it the special theme of their works, and have brought all the conclusions of anatomi- cal and physiological science and the principles of the correlation and conservation of force in support of their argument that the brain is the only and sufficient mental organ. Of the authors who have treated the subject from this point of view may be named Bastian and Maudsley of England, Luys of France, and Moleschott, Vogt, Biichner and Haeckel of Germany. Many other authors might be named who have dealt with it more or less directly, prominent among these being Huxley. The con- verse has also been taken by several authors, yet none of them can be said to have squarely met the arguments of their oppo- nents, and the most of them have dealt with it in the old and vague metaphysical method. So far as a scientific treatment of the question goes, the brain-mind theorists seem to have the best. of the argument. And yet to the present writer their arguments seem the reverse of satisfactory, and their theories to need much Stronger lines of evidence before they can be made self- sustaining, That the brain is intimately and constantly concerned in the manifestations of the mind, no one will deny. But that it is alone concerned is far from being proved. The theories pro- posed by the several authors are the following: Huxley declares _ that sensation and consciousness are in some inexplicable way caused by molecular changes in the brain. This belief is based on the facts that thought and motion seem inextricably related, that every thought is accompanied by brain waste, that heat 850 The Relations of Mind and Matter. (September, appears as a consequence of thought, that mental action cannot go on without a constant supply of arterial blood and must cease periodically until the brain can regain its integrity through the assimilation of nutriment, and finally that no other organ of the mind can be discovered. The latter point, however, can be left for future consideration. It will suffice here to say that if such an organ does exist, though imperceptible to the anatomist, and if the brain is its instrument of activity, the above-named cere- bral phenomena would be as necessary as on the brain-mind theory. The earliest effort to definitely deal with this question is that of Cabanis, who advanced the idea that the brain acts like a gland, and secretes thought. This idea made a decided ripple in the thinking world, though it has long since died out. Maudsley’s idea is that every sensory impression upon the brain leaves be- hind it some modification of the nerve elements. This he con- siders to be the physical basis of memory. He looks on the change that takes place as a motion, which he considers analo- gous to the “compounds, and compounds of compounds, of vibrations in music.” Other authors propound like views, and consider thought to be a persistent vibration of the nerve fibers of the brain. Luys offers the same idea ina fuller shape. He says: “I have proposed to apply the term phosphorescence to that curious property the nerve elements possess of remaining a longer or shorter time in the state of vibration into which they have been thrown by the arrival of external excitations; as we ` see phosphorescent substances illuminated by solar rays con- tinue to shine after the source of light which has illuminated them has disappeared.” This is the present state of the brain-mind theory, as advanced by its most ardent and learned advocates. The only definite conclusion to which they can arrive is, that thought is a persistent vibration of the cerebral nerve fibers. Indeed there is no other theory open to them, The discoveries of late years hinder them from taking refuge in the powers of a brain cell of unknown Organization. It has become evident that the brain cell is essen- _ tially a mass of very delicate fibrillæ which are continued through _ the nucleus, and in all probability are continuous with the nerve “fibers, Thus we have nothing but fibers of greater or less 4 minuteness to deal with, and it seems to follow as a necessary 1885.] The Relations of Mind and Matter. 851 consequence that if thought is nerve motion it must be some motion of elongated fibers. This motion enters the brain as a mode of vibration in these fibers, and we can conceive of its per- sistence in or on them in no way except as a vibration. Yet to theorize about a persistent vibration is to theorize on the impossible, and to set aside all the results of the science of acoustics. There is no such thing in nature as a vibration per- sistently active in a limited region. No limited chord can vibrate unceasingly. Its vibrations must be rapidly transmitted to the surrounding material, or be converted into some other mode of motion. Otherwise the chord would have to be surrounded by a perfect vacuum, and be utterly free from friction. No such conditions exist in the brain fibrilla. Thus a vibratory nerve current, even if transferred by induction to a closed cerebral cir- cuit, could not possibly retain its original condition. It must make its way onward, be transferred to surrounding. material, or be quickly transformed into some other mode of motion. The conditions of the mental organism require that this mode of motion shall be an organizing one, a persistent motor affection of some substance. The brain fibrille, which are essentially con- tinuations of the nerve fibers, cannot constitute such a definite and self-centered organism. Neither can the cell substance sur- rounding these fibrilla. It is to this granular or homogeneous protoplasm seemingly that the cerebral activity is due. The motor impulses conveyed inward by the fibers appear to instigate chemical changes in this substance precisely as they do in the muscle substance. It falls into a lower stage of integration and sets free the energies which arouse the mind to action. Thus the brain cells seem solely instruments of the mind. But for them the mind would remain dormant. They yield, under the influence of external impulses or of impulses derived from the mind itself, energies which call the mental organism into activity. But this very evident characteristic, and the constant cerebral changes which it occasions, strongly indicate that the mental organism is distinct from the cerebrum, though to all appearance very intimately connected with it. It may seem absurd to speak of the existence of an organism thus related to the cerebrum yet not evident to our senses. Yet the more we consider the brain as the organ of mind the less does it seem adapted to the duties thus imputed to it. It has of late VOL, XIX,—NO, IX, 56 852 The Relations of Mind and Matter. (September, been rendered almost certain, by the researches of Ferrier and others, that each region of the cerebrum has its special duties, to the performance of which it is strictly confined. Here sensation seems to center; there motor impuls¢s arise. Into this locality flow the sensations of sight; into that locality those of taste or smell. Speech has its center here; the motion of a particular muscle there, Instead of the whole brain being concerned in every action, each limited portion seems to be immediately and strictly related to some fixed sensory or motor region. The evidences of this are as yet somewhat broad and general, yet they are steadily growing more precise and particular. Every nerve fiber proceeding from a sensory end organ or a group of muscle fibers may connect directly with a special group of brain cells, and possibly every fibril of these fibers may terminate in a single brain cell at one extremity, and in a single muscular fibril or sensory point at the other. If such were the case the brain would be closely related in condition with the outer terminations of the nerves, and the nervous system would consist of a vast series of fibers diverging outwardly to terminate in a widely separated series of sensory and muscular cells and fibrils, and converging inwardly to terminate in a closely aggregated series of nerve cells, the latter being as individual in their duties as the former, despite their much closer grouping. This, of course, is purely hypothetical, yet the special relation of groups of brain cells to groups of sensory or muscle cells or fibers has been established by experiment, and it is not safe to limit the possible minuteness of this relation. Yet the existence of such a relation seems to stamp the brain as the instrument of an interior mental organism. In the operations of the mind there is no evidence of such a disconnected series of duties. The mind constantly impresses us as an intimate unity. Its thoughts are in continual rapport, and call up each other with instantaneous rapidity. Such a relation could not well exist between the imag- ined localized vibratory energies of the brain. If each locality were capable of sending ‘its vibrations at will to any other local- ity, and rousing into activity the energies of distant regions, what is to hinder the complete dissemination of these energies? If o such a condition existed, the fibrils of every cell in the brain "must soon become affected with a vast multitude of diverse and _ frequently discordant pulsations. And it is impossible to imagine 1885. ] The Relations of Mind and Matter. 853 how such pulsations, even if their continued local existence were possible,.are to be thus restrained and confined. They are capa- ble at intervals of flowing out upon the fibers of the motor nerves. What hinders them from immediately flowing out? By what power are they retained, so as to be let off at arbitrary and far separated intervals? And when once such vibratory energies are set free upon the motor nerves how can they still exist in the brain? Thought is persistent, yet on this theory it could only be persistent if it never produced any effect. Motion cannot be increased or diminished at will. It cannot be discharged and yet retained. It cannot become an outflowing radiation while still existing with undiminished vigor as an organizing agent. The problem of consciousness comes into the question here. If thought be a persistent motor affection of the nerve fibrils, and if consciousness is an accompaniment of all active thought, why then are we not steadily conscious of all our thoughts? Are we to look upon consciousness as a separate traveling agency, which moves irregularly from part to part of the brain, and adds a new increment of activity to every thought with which it momentarily combines? We can in no other way explain the vagaries of con- sciousness on the brain-mind hypothesis. Again, if the brain is the organ of the mind, one of two things must be true. Either every brain cell must contain a special por- tion of the mental energies, or, if the thought vibrations can make their way everywhere through the brain, every cell must be a miniature copy of the whole mind. The localization’ of the powers of the brain is an argument for the former. The close interrelation of thought seems to necessitate the latter. The dilemma of the brain-mind theorists has its two horns of diffi- culty, and it becomes incumbent upon them to harmonize these opposed conditions. Another difficulty connects itself with the preceding, This is, that the cerebral cells are not permanently in existence. Every action is attended by cell waste. The old cells die and new ones take their place.’ Or new ones arise by. the process of cell division. If the cells are reservoirs of special motor forces, what becomes of these? Are they transmitted hereditarily to the new cells? This can hardly be, since the death of the old cell is often a consequence of the transmission of its special energy to motor nerves. It cannot, therefore, trans- mit more than its general organizing energy to new cells, The 854 The Relations of Mind and Matter. [September, germ cell of an animal exists as a remarkable counterpart of the general energies of its parent, and the offspring develops into a close copy of the parental physical characteristics and mental conditions. Yet the special knowledge of the parent is never transmitted to the child. Unless the latter gain special knowl- edge of its own, it will remain in this respect undeveloped. So one cell may transmit to its successor its organizing characteris- tics, but scarcely its more delicate special motor conditions. In fact, the more we consider this hypothesis the more unsat- isfactory does it appear. If the brain is to be looked upon as a material organism, a machine with thought for one of its products, we might naturally expect to find some analogy to its mode of action in other machines. It is credited with a double duty. It is a receiver and dispatcher of nervous impressions, and it has a special discriminating power as to how, when and whither it shall despatch these impressions. What is there in the brain to decide which impressions shall be retained and which transmitted? Are there special resistances in some cells of the brain which hinder the transmission of sensory impressions to the muscles? If so, how come these resistances to break down at such arbitrary periods. What principle makes some cells resisting and others non-resisting? How is it, again, after this resistance has yielded, and the motor energy flowed out to the muscles, that the thought which it represents is still found intact in the mind, and usually stronger than before? What machine is it that has its energy within itself and still possesses it after using it to set a train of wheels in motion? And finally, how do we explain the peculiar relations of consciousness to these thought impressions ? - All this presents no difficulty if we can conceive of a mental organism distinct from, but in the most intimate relation with, the cerebrum, upon whose separate regions its thoughts play, like the fingers of a performer upon the separate keys of a piano. The same finger may touch many keys in succession and bring outa special tone from each.” The player may be a single organism, & resultant of organizing motor energies inherent in a definite mass = of substance, while the instrument may be made up of many sep- arate parts, having only general and no intimate interrelations. : The player may bring out what sound he desires, but it would _ not be easy for one key to emit another sound at will, or to force another key to emit its special sound. And even if the piano 1885. | The Relations of Mind and Matter. 855 key had a reservoir of energy by which, at some arbitrary period, it could suddenly spring into activity and yield a peculiar sound, evidently a part or the whole of this special force must be ex- hausted in doing so. But if struck by an exterior organism the latter might be strengthened by the exercise, as a muscle is strengthened by use. This is a characteristic feature of mental action. Its special energies, or its thoughts, are strengthened by use. It seems evident that such a condition can only exist in the case of a definitely centralized organism, affected by motion as an organizing agent, and also by generalized motions, which it has the power to divert in certain directions without detriment to its organization. Such is the human body, It is definitely organ- ized by the double agency of chemical affinity and inhering motions, which limit the condensing action of affinity. In addition it is the seat of heat, electric and other motions, which it can employ as agents of external action. The mind, as an organism, displays these same characteristics. It is organized by permanent motor conditions. It receives and emits definitely directed motions. And its organization is affected and developed through this activity precisely as the organization of the body is aided and modified by the energies which it receives and emits. The parallel is a close one, and indicates that the mind, like every organism in nature, is a self-centered mass of substance, held together by affinity and organized by inherent motions. There is-nothing in the conditions of the cerebral organ to in- dicate that it is such a single, definite organism, or that it is capable of manifesting the peculiar phenomena of the mind. The great difficulty in the brain-mind theory is that the machine can- not contain within itself the voluntary will power of the engineer. If thoughts are the motor energies of the brain matter it is simply © incredible that they could arbitrarily retire from and reénter the field of activity. The character of their activity must be fixed, con- stant and unvarying. And the effects they are capable of pro- ducing must be immediately or incessantly produced. It is im- possible to conceive of a seif-acting machine under any other relations. All its energies must be steadily in activity, and its effects on outer matter must be limited and constantly similar. We cannot imagine such a machine arbitrarily changing its action; now producing one effect, now another; now acting on 856 The Relations of Mind and Matter. (September, one substance, now on another; its different parts irregularly rising into activity or sinking into quiescence ; and its energies continuing unchanged and inexhausted through all this varied outflow of motor activity. No instance of the kind was ever seen or can be imagined to exist. The existence of such arbi- trary and seemingly voluntary activity irresistibly leads to the inference of a separate agent overruling the action of the machine, and now calling this, now that part into activity. On the theory of self-action of any instrument it is impossible to admit the existence of arbitrary and irregular variations of activity like those of the mind. On the opposite theory that the mind is an organism separate from the brain, and using the latter as its instrument, we can readily comprehend the varying action of the instrument. If the two be in close but not in constant connec- tion; if the mind now makes contact with one group of brain cells, now with another, and now withdraws from all contact, the difficulty diminishes. Why these varying contacts takes place is a question of a different character. They may be due to influ- ences of affinity or polarization, which are subject to change under the changes in cerebral conditions which they induce. Or they may be otherwise produced. It is difficult to understand the cause of such seemingly arbitrary contacts; but this diffi- culty is not an impossibility like that attending the brain-mind theory. And underthe idea that the mind is a separate organ- ism we can understand the vagaries of consciousness, which can-, not possibly be done under the brain-mind hypothesis. This subject will be considered later. There is one more consideration to which we may briefly advert. The cerebrum is subject to pathological changes. It frequently becomes incapable of doing its duty properly. In many instances of cerebral disorder the mind seems to disappear. A whole series of mental conditions may utterly vanish, and remain lost for years. A new series of mental conditions may be built up. Or every trace of intelligence and consciousness may disappear and the body act as a mere automaton, governed by reflex action only, or possibly by the deeply based hereditary -Or instinctive mental powers. And yet, after years of this mental _ obliteration, there are instances on record where the brain recov- ered its normal condition and the mind reappeared with all its rme - contents of memories, opinions and ideas. Such a cif . 1885.] The Relations of Mind and Matter. 857 cumstance it is impossible to comprehend under the theory that the thoughts are but motor affections of brain matter. In these years of disorder it is absolutely certain that considerable modi- fications must take place in this matter. The motions affecting its cells and fibers cannot continue absolutely the same as they were years before, but must have become greatly changed and reorganized under years of influx of external energies. But if we view the mental organism as separate from the cerebrum these strange phenomena lose much of their mysteriousness. In that case the disorder of the cerebrum may not have directly affected the mind, but simply broken the connection between the mind and its organ of manifestation and development. The men- tal organism may lie for years intact, as a crystal lies buried in its bed of rock. It retains its original conditions since it has been removed from the influence of disturbing energies. And when once again it regains its powers of manifestation, through the regained normal condition of the cerebrum, it must reappear in the precise condition which it had attained at the period of the broken connection, and with all its memories and ideas intact. If we consider the relations of the nervous system from this point of view, we perceive it to be composed of a vast aggregate of fibers, which divide into their constituent fibrillz in the gan- glion cells. These fibers are in contact, at their opposite extremi- ties, with two distinct sources of energy. One series of them — runs from the brain to the sense organs on the surface. Another series runs from the brain to the muscles, The first series has its receptive extremities at the surface, and conveys the energies of external nature to the brain to discharge them into the mental organism. The second series has its receptive extremities in the brain, and conveys energies received from the mental organism to the muscles, there to discharge them. Each of these fibers apparently has its fixed and single duty. If one of the sensory nerves be touched, it carries an impression to a fixed locality in the brain. If one of the motor nerves be touched, it carries an impression toa fixed muscle. The more deeply anatomy and physiology search into the conditions of the nervous system the more clearly it appears to be simply such an instrument for the conveyance of impressions to and from two sources of energy, an external and an internal one, and the less fitted does it seem to sustain the theory that the brain is the organ of the mind. * 858 The Exhalation of Ozone by Odorous Plants. (September, THE EXHALATION OF OZONE BY ODOROUS PLANTS. BY DRS. J. M. ANDERS AND G. B. M. MILLER, A the AmeERIcAN Naturauist for April and May of the year 1884, there appeared two articles, by one of us, treating of the “ Exhalation of Ozone by Flowering Plants.” The reader will there find recorded the results of numerous experiments which were made with the view of ascertaining whether or not plants have the power to generate ozone. The chief conclusions there- from deduced were as follows: 1. That flowering plants in gen- eral are capable of generating ozone, and odoriferous flowers in particular. 2. That foliage plants do not possess this function. It should be remarked that the present re-investigation of the subject was undertaken with the view either of confirming or dis- proving the correctness of the above conclusions. Owing to the high importance of the question of the relation of plant growth to the generation of ozone, this course was deemed almost incumbent, As the more important properties of ozone were discussed in the previous papers, it is not deemed necessary to do so here. The hygienic relations of this substance also received brief atten- tion while its tests received careful consideration ; hence to fur- ther enlarge upon these phases of our subject, at present writing, would be a work of supererogation, The methods employed in the former experiments were likewise used in the present series. The following apparatus was used: A glass case large enough to contain a dozen or more thrifty growing plants in pots. Its dimensions were, length three and a half feet, width two and a half feet, and height two and a half feet. A portion of the top was left removable, so as to furnish an aperture through which the plants could be placed in the case and again taken out. The tests employed were the Schoenbein paper and paper im- pregnated with tincture of guaiacum. When exposed to ozone 7 artificially prepared the Schoenbein paper turns quite blue, while __ the guaiacum paper first turns greenish-blue and finally a bright blue. In the present experiments we also employed the same _ terminology, viz., “marked,” “slight” and “very slight,” to _ denote the degree of blue coloration. — A dozen thrifty plants belonging to the species Coleus lumei, > 1885.] The Exhalation of Ozone by Odorous Plants. 859 not blooming, were first selected and placed within the glass case. The test papers were moistened and suspended on the branches of the plants. After adjusting the removable part of our case, the latter was found to be pretty well filled though not over- stocked with plants. For the purpose of detecting any alkaline substance whose presence, it is said, will change the Schoenbein and guaiacum pdpers in a manner indistinguishable from that produced by ozone, we suspended with the test papers a piece of red litmus, with the results indicated in the following tables. The air on the exterior of the case was simultaneously tested for ozone. In view of the fact that these tests are in an unsatis- factory state, the necessity for taking precautions against inter- fering conditions must be obvious to the mind of the scientfic reader. ; The following table will serve to show the results obtained from the specimens above named for seven consecutive days in the month of June, 1884: : ; s Schoenbein : State of | Litmus No. experiment.| Schoenbein, Guaiacum. $ open wir.

It should be remarked that whilst two “slight” reactions occurred with the Schoenbein paper, they were probably due to the presence of some alkaline substance, since on the same days the red litmus was changed to a “marked” blue. Thus, after repeated experiments, it would appear certain that it cannot be claimed for non-odorous foliage plants that they are ozone-generating. Though the guaiacum Paper gave “ slight” reactions in three experiments which yielded no results with the litmus paper, it should be here noted that Owing to the fact that this paper (guaiacum) is materially affected by various atmospheric conditions, we did not much rely upon the results obtained from its employ. On the other hand, if _ Proper precautionary measures be taken, the Schoenbein is, doubtless, of all the tests for ozone the most reliable. 860 The Exhalation of Ozone by Odorous Plants.

It will be observed that sufficient ozone was gen- erated in four of the experiments to give one “marked” and three “ very slight” reactions ; also that the litmus gave no indi- cations of the presence of ammonia. Although they do not rank as active ozone-generators, nevertheless they must, from the facts of the case, be looked upon as sharing this important function in a slight degree. This decision also coincides with what had been previously demonstrated by experiment. e now made a trial of odorous flowering plants, selecting for this purpose seven roses and seven specimens of Lilium longi- Jorum. After carefully enclosing them within the case, the atmosphere of the latter was tested and simultaneously the aif outside, with striking results as shown by the following table: ae g i TN hoenbein| Litmus w State of cite experiment.| Schoenbein.| Guaiacum.

Since this 1885. ] The Exhalation of Ozone by Odorous Plants. 861 function is so actively carried on by odorous flowers, it oc- curred to us to make a trial of plants whose leaves emit odors but having no flowers.. Blooming geraniums having been ex: perimented with while making previous researches into the same subject, and having found them to be capable of generating ozone, it was determined to employ a number of specimens belonging to the genus Pelargonium not in bloom, with a view of ascertaining whether the reactions obtained with flowering gera- niums were due to the presence of the flowers, or whether they were due in part to the odorous principles emitted from the leaves of the plants.

Upon this point, however, the evidence afforded by the results of the present set of experiments alone is too slender on which to base positive conclusions, and hence we deemed it desirable to make further observations upon foliage possessed with marked perfume. To aid in clearing up this subject it was next resolved to make tests with pine foliage, possessing the well-known tere- binthinate odor, and in the results obtained we were not dis- appointed, Seven branches taken from the species Pious strobus were introduced into the case in the upright — when the same 862 The Exhalation of Ozone by Odorous Plants.

These facts doubtless account for negative results after the fourth day. It should be stated that we contin- ued to test them on the sixth and seventh days respectively, and with negative results in both of the latter instances. We were, however, encouraged by the success attending the first three experiments, and resolved to make another trial of pine branches: Accordingly we again selected a half dozen pine branches which moderately filled our little floral chamber, and allowed them to remain only until they began to show a change in color, which change was first observed at the end of the third experiment.

Although a greater number of experiments upor fhis point could have been desired, when, on the one hand, d how great and numerous the difficulties connected 1885. ] The Exhalation of Ozone by Odorous Plants. 863 with the making of such tests, and on the other, the brilliant and very uniform success of the experiments made with pine foliage; it will be readily conceded that these facts furnish abundant evi- dence of the power the odorous principles evolved from the pine tree have to generate ozone From the foregoing, in conjunction with former investigations into the same subject, we are, at present writing, justified in formu- lating the following conclusions; First. That flowering plants, including odorous and inodorous, generate ozone, the former, however, much more actively than the latter. Secondly. That so far as tested scented foliage does possess the power to produce ozone, and. in the case of pine or hemlock foliage in a marked degree, Thirdly. That inasmuch as no reactions \gdedttéd on rainy days, it is highly probable that the function demands the influ- ence of the sun’s rays or at least good diffused light. In comparing the present with former conclusions, cited at the commencement of the paper, it will be seen that they differ in so far as relates to foliage plants only, those pertaining to flowering vegetation being perfectly concordant. As to the mode in which the ozone is developed by plant life, or in other words, as to what is the nature of this ozone-gener- ating function, the following explanation was elsewhere merely suggested (loc cit.) : “It is known that the ashes of seeds con- tains large quantities of the phosphates. It follows that during the formation of the seed there is a rapid metastasis of the phos- phorus in the form of phosphoric acid, and the phosphates to that organ of the plant, and it may reasonably be supposed that in the chemico-vital interchanges going on in the ovules, phos- phorus is liberated and acted on by the moisture which the leaves are so actively transpiring. * * * The subject, how- ever, merits further investigation.” In view of the facts estab- lished by present researches the theory of the production of ozone by vegetable growth above cited must be abandoned, and it appears evident, from present premises, that in some way the odoriferous principles emitted, whether from flower or foliage, are chiefly concerned in its formation. It is true we are unable in this manner to account for its production by odorless flowers, unless, as many contend, we grant that all blossoms are either 864 The Exhalation of Ozone by Odorous Plants. [September, bedecked with or, somewhere in their loose cellular tissue, con- tain scented nectar which in many so-called inodorous flowers may not be sufficiently pronounced to be perceived by the organ of smell. It is a well-established fact that wherever fertilization is accom- plished by insects, so-called mectaries are somewhere found in the flowers. These organs are described by Sachs as follows: “ The nectaries are often nothing but glandular portions of tissue on the foliar or axial parts of the flower ; very often they project in the form of cushions of more delicate tissue or take the form of stalked or sessile protuberances; or whole foliar structures of the perianth, of the andrcecium or even of the gyncecium, are trans- formed into peculiar structures for the secretion and accumula- tion of the nectar.”? The proportion of plants where pollination is effected by insects is certainly large, and when we take into account those flowers in which cross-fertilization occasionally results from the aid of insects, this proportion is still very much larger. Whether it can be claimed for all inodorous flowers that they contain a greater or lesser number of nectaries we are not prepared to state, but it is certain that numerous flowers, which are classed as being without fragrance or any other odors, such as the geranium, the passion flower, etc., are visited by insects, and these must therefore con- tain glandular ‘tissues filled with an alluring secretion. The question also naturally here arises: Are there not flowers that are never visited by apects, which flowers possess these glandular organs? Our investigations did not include an examination of these organs, but there is evidently an interesting subject here pre- sented for further experimental study. The theory that the fragrant emanations from flowers, as well as all the various odoriferous substances emitted from plants, stand in close relation to the ozone-producing function in plants likewise receives striking corroboration in the well-known chemi- cal fact that the volatile perfumes and the strongly-scented aro- matic substances have the power to convert the oxygen of the atmosphere into ozone. e application of the results of our experiments to the rather "old but highly i ing subject of the cultivation of house plants isaw Text-book of Botany, p. 500, 1885. | Glacial Origin of Presque Isle, Lake Erie. 865 is of considerable importance. That phase of the question, how- ever, pertaining to flowering plants has been elsewhere treated, It remains to speak of the sanitary relations of the new and addi- tional fact which has been established by the present experiments concerning odorous leaves as ozone-generators. Owing to the fact that few varieties which have markedly odorous leaves are cultivated within doors, their sanitary bearings may be regarded as being slight, the leaves of the geranium and other species usually seen in dwellings being feeble in their ozone-generating properties. Again, it should be remarked that when kept in- doors the odors given off both from the flower and foliage are sometimes not only objectionable to the senses, but also may prove detrimental, It is evident that such plants should be dis- carded, The case is widely different when we apply the results of our labors to the question of the hygienic value of out-door vegeta- tion, and more particularly of pine groves. Under these circum- stances unpleasant odors do not form a positive objection, whilst the species emitting the most pronounced odors are capable of rendering valuable hygienic service by furnishing ozone to the surrounding medium, Since the exhalations from the pine foliage are active agents in generating ozone, it follows that all of the important hygienic advantages of ozone are to be derived, to a marked degree, from the presence of pine woods.’ :0: GLACIAL ORIGIN OF PRESQUE ISLE, LAKE ERIE. ‘BY T. DWIGHT INGERSOLL, HE peninsula of Presque isle is an extension of the main “ land opposite the city of Erie, Pennsylvania, reaching out into Lake Erie in a north-eastern direction. It is crescentic in form, the convex portion facing the lake with the shore line bend- ing toward the mainland, and forming Erie harbor, which is known also as Presque Isle bay. The. bay is about four miles in length by about two in breadth, with an entrance on the east. Government operations have made the bay somewhat historical, The vessels of Commodore Perry’s fleet were built here in 1813, 1 For a fuller discussion of the subject of the sanitary relations of pine forests, see article by J. M. Anders, on “Sanitary Influence of Forest Growth,” a paper read before Phila, Go. Med. Society, Oct. 22, 1884. 866 Glacial Origin of Presque Isle, Lake Erie. [September, and after his victorious battle the Lawrence and flag-ship Magara lay in the bay until the centennial year, 1876, in front of the old block-house on Garrison hill, where General Anthony Wayne . died and was buried in 1796. When the peninsula was first occupied by Government soldiers it was several feet broad at the junction with the mainland and covered with large forest trees, but the constant action of waves, since that time, has reduced that portion to a narrow neck of land over which the waves have, during the past year, rolled into Presque Isle bay. There is a strong probability that before the expiration of the year this tract of land will be transformed into a traveling island en route to Niagara falls, unless something is done to protect it from lake storms. * For a consideration of this matter there was a meeting of the Erie Board of Trade on Janu- ary 5, 1885, at which Ex-judge John P. Vincent said: “Since I came to Erie, in 1839, the north arm of the penin- sula has moved several rods, and the east end extends fully a mile further than it did then. If something be not done the peninsula will waste away at the head and build up at the foot, and eventu- ally the harbor will be below the city.” Engineers, however, have estimated the increase of land at the lower end to average only thirteen feet per annum. All this material—sand and pebbles—has been washed from the north shore, principally from that portion near the head, and when it reached the foot an eddy was formed around it, the sand falling to the bottom and becoming new-made land. Sometimes this material was carried past the peninsula too far for a union with the foot, and a bar and perhaps an island was formed, against which other sands lodged. At some subsequent time we may sup- pose that the eastern portion of the new formation was broken up by opposing easterly gales, and the sand carried along both sides of the new island toward the west until a union was formed with the peninsula, shutting in between the two connect- ing bars of sand a pond of water, and the island thereby became the foot of the peninsula, receiving further increase. In this way it is supposed that several fish-ponds, now in existence on the peninsula, have been formed. _ From the briefly sketched history of Presque isle the reader _ May naturally be led to inquire into its origin. The writer at one time imagined that there might have been a small uplift of rocks under the surface such as he had seen on the mainland in the 1885.] Glacial Origin of Presque Isle, Lake Erie. 867 vicinity ; but after a personal investigation and inquiry of civil engineers, he came to the conclusion that the land is composed entirely of sand, clay and rolled pebbles of foreign and native rocks. History shows that this material has not only been changeable in form, but small quantities have from time to time been trans- ported from the western to the eastern portion by the waves. These changes must have been in progress prior to its discovery, and of course the peninsula was situated further west than it is now. This we may regard as a clue to the origin of the penin- sula however hypothetical it may seem to be. The material being almost identical with glacial drift that is scattered all over Northwestern Pennsylvania, which in some places is nearly 200 feet in depth, and may have had the same origin, having been deposited at the same time about twenty miles west of its present site, where the Devonian strata dip gently under the surface of the lake. At that point a vast quantity of glacial drift was shoved upon the sloping rocks during the ice age, and that de- posit has been the sport of the waves ever since the retreat of the great northern glacier. Professor I. C. White, of the Pennsylva- nia State Geological Survey, says: “The varied character of the northern drift deposits can be well studied along the shore of Lake Erie, towards the Ohi State line, where they constitute a terrace bluff from fifty to eighty feet high, out of which the waves are constantly removing the clay and fine sand into the Jake leaving the coarse sand, pebbles and boulders to be daily rounded and polished on the beach.” At the close of the ice age the waves began to wash away the finer particles from the bluff of drift, and as the current of the water was down the lake in a north-eastern direction—the storms Moving generally the same way—the probability is that a bar of ‘sand was formed at some favorable place east of the starting point, upon which other material was driven year after year until an island or peninsula was formed. At some later period more powerful storms broke up the western portion and carried it along to or beyond the eastern extremity, while it was being constantly enlarged by sand from the original source, and from the bluffs and watershed along the shore, which was brought down by numerous streams. In this way let us imagine the bar an island or a peninsula, and alternating perhaps with each other until the erratic bodies‘of land appeared to the first white settlers of this region in form of a peninsula.

The sedentary Negroes subdivide into. plantation Negroes and city Negroes, these latter forming forty- seven percent of the whole colonial population. Specimens of the takitaki jargon are appended.

Also the ape-like characters of the Neanderthal skull are perhaps over stated. As we under- stand it, Wyman found quite as brutish a skull in the Indian mounds of Florida. The evidence has yet to be afforded that the earliest known race of man in Europe was any lower than the lowest existing savages. Such evidence, may however, be forth- coming any day.

Asia—The Badghis district —This district in Northern Afghan- istan, north of the watershed of the Herat valley, consists ot hills and valleys of sandstone clay, the hills rising from» 200 to 600 feet, or even to 1000 feet, between two great streams. Though sand-covered and desert-looking in autumn, they are not only cultivable on their lesser slopes but exceedingly fertile, and in spring are covered with flowers and grass knee-deep, The north- ern and western parts have little running water, but the eastern and southern portions, along the Parapomisus and the Kushk rivers, are exceptionally fertile. Sir Hy. Rawlinson states that the Bundehesh, a work compiled before the Arab. conquest (in the fourth or fifth century) derives “Badghis” from the tribe of e Vad-Keshan or “ wind-worshipers.” Coins of the Kushan or Tokhari show that these tribes did worship the wind. They were commonly called “ White Huns,” came into the land in the fourth or fifth century, and had for their capital, Talikan, thirty or forty miles east of Maruchak, Badghis (Kileh-Maur) was their strong place. The Pescadores—The Pescadores, recently bombarded and occupied by Admiral Courbet, are in the Formosa channel, about twenty-five miles from Formosa. The largest is Panghu, and the Chinese name for the group is Panghuting or the _ Panghu district. Panghu is forty-eight miles in circumference, and the next in size, Fisher’s or West island, is seventeen. The nty-one inhabited islands besides several rocks. Trees are : ie " i ; i lit i by w. N.

The islands offer shelter in all states of the weather in the dangerous Formosa channel. Port Hamilton.—Port Hamilton was stated, by Mature, to be identical with the large Corean island of Quelpart, about sixty miles due south of the extreme point of Corea. It is 150 miles from Shanghai and 100 from Nagasaki, and lies in the mouth of the only exit to the south from the Sea of Japan. It is an oval rock-bound island covered with innumerable conical mountains, often topped by abrupt volcanic craters, the highest of which, Haura, or Mt. Auckland, is 6500 feet high, and bears at its sum- mit three craters, within each of which is a lake of pure water. Corean children are taught to believe that the three first-created men still dwell in these lofty heights. The island is well culti- vated, and contains three walled cities and several towns, but has are the best in Corea. Iron appears to abound on the southern coast. Nature and other English papers were, however, mistaken in the statement that the large island of Quelpart i is identical with Port Hamilton, which is marked upon German maps as situated somewhat to the north of Quelpart, and is formed by three rocky and elevated islets, Asiatic Notes—The name Pamir applies generally to the whole region lying at the sources of the Amu-daria. The word is derived from dam, roof, and perhaps the Kirghiz zr, earth. It extends in the shape of a horse-shoe from north to south 200 miles, and from east to west 170 miles.

Though the name signifies a sand desert it is not sandy throughout. The sands are of three kinds. The first is clayey, mixed with sand and covered with small hil- locks and brushwood ; the second kind consists of real sands which do not drift to any great extent, the drifting portion form- ing ridges or hillocks ; but the third kind, the true ġarkhans or shifting-sand deserts, are without so much as a visible grass blade. Beside these different kinds of sands there are, in the Kara-kum, kyrs or tracts of firm clayey surfaces (mixed with sand) consist- ing of valleys alternating with eminentes 140 to 210 feet high; takirs, or flat clayey areas surrounded by sands; and shors or tracts of hard ferruginous sand lying in the lowest parts of the desert. The /zvestia gives an account of M. Potanin’s journey from Peking to Lang-tcheou, in 1884. The country between the Yellow river and Boro-balgasun is covered with sand, rarely moving sand, but darkhans fortified by a growth of shiabyk,a species of Artemisia, with bushes of Cavagana in the cavities be- tween. Water is plentiful. The dry grounds between the sands are covered with steppe vegetation, and sarrazin, millet and hemp insurrection was put down. Lin-tcheou, on the Hoang-ho, is surrounded by fruit gardens, and for fifty miles south of it numer- ous villages extend along a canal which runs parallel to the Ho- ang-ho. This richness is of recent origin, for the whole region bears traces of the desolation wrought by the Chinese after the suppression of the insurrection, of which the town of Tsin-tsi- u was the center. South of this town M. Potanin left the Hoang-ho and crossed the series of flat ridges which rise from OO to 7000 feet above the sea, and are covered with loess to a thickness of 200 to 300 feet.

Mirambo is also dead. The Royal Geographical So- ciety has decided to send out another expedition under Mr. J. T. Last, who will: proceed to the confluence of the Rovuma and Lujendi rivers, fix the longitude of the junction, and will then establish himself awhile at the Namuli hills. After a study of this region, Mr. Last will enter the valley of the Likugu, follow it to the coast, and then follow the coast to Quillimane or An- goche, The Portuguese possess a tract of land on the north- ern bank of the Congo, extending from Cape Lembo, south of Kabinda bay, to Massabé, and extending inland thirty or forty miles so as to contain Kabinda, Molembo, Landana and Massabé. The whole of the valley of the Kwilu, where the International Association had eighteen stations, is ceded to ance. Parts of the countries of Useguha, Nguru, Usagara and Ukami have, by treaty with “ten independent sultans,” been brought under the protection of Germany. The com- mercial importance of this district is great, since the central trade route to Lake Tanganyika passes through it. After fifty to eighty miles of unhealthy coast region is passed, mountains and plains with much fertile country and sufficient water are reached. The Wa-ngaru, Wa-sagara and Wa-seguha speak nearly the same dialect. The King of the Belgians has resolved to abandon Ka- rema and other stations of the association east of Lake Tan- ganyika. The territory now claimed by Germany in East Africa is usually supposed to recognize the authority of the Sul- tan of Zanzibar. The rule of this potentate is acknowleged along trade routes for at least 700 miles in the interior, and also by many chiefs away from these routes. The sultan owns 1050 miles of coast besides islands. In spite of the succession of misfortunes which beset M. Giraud, he has added greatly to our knowledge of Lake Bangweolo. The Luapula leaves the south- west corner of the lake, as shown on Mr. Ravenstein’s map.—— Capt. G. A. Chaddock has ascended the Limpopo for a consider- able distance. The channel at the bar is narrow, with no less than four and a half fathoms of water. A long sandspit, three miles from the coast, forms a natural breakwater, and the water at the opening is fresh. The river channel is narrow and deep, the surrounding country low and level, and thickly populated. The lower course has no trees save some mangoes at the mouth, Captain Chaddock believes that the Limpopo is free from falls or any obstruction as far as the Transvaal. America.—M.

Tae RELATIONS oF THE PaLzozorc Insects —At the aoe "modification I would ftitrodtice is to this effect: That 1885.] Geology and Paleontology. 877 while we may recognize in the Palzozoic rocks insects which were plainly precursors of existing Heterometabola, viz., Orthop- tera, Neuroptera (both Neuroptera proper and Pseudoneuroptera). Hemiptera (both Homoptera and Heteroptera) and perhaps Col- eoptera—and no Metabola whatever—a statement almost identi- cal with that previously made, we may yet not call these Orthop- tera, Neuroptera, etc., since ordinal features were not differentiated ; but all’ Palaeozoic insects belonged to a single order which, enlarg- ing its scope as outlined by Goldenberg, \ we may cal Palæodic- tyoptera; in other words, the Palæozoic insect was a generalized Hexapod, or more particularly a generalized Heterometabolon. Ordinal differentiation had not begun in Palæozoic times. The grounds for this view are as follows: 1. No group of Palæozoic insects has yet been studied care- fully; and it is important to observe that, though our knowledge of them is of necessity fragmentary, yet the more perfectly they are known the clearer is this true; no group, I say, has been carefully studied which does not show, between it and the mod- ern group which it most resembles, emer en so great that it must be separated from that group as a whole, as one of equal . taxonomic rank, as in the case of three felative groups last mentioned. 2. That the different larger groups of Palzozoic times, of which we now know nine or ten, were more closely related to one another, at least in the structure of their wings (which is the only point of general structure yet open for comparison) than any one of them is to that modern group to which it is most allied, and of which it was, with little doubt, the precursor or ancestral type. Thus the Palæoblattariæ are more nearly allied in the ground structure of their wings to certain neuropteroid Palzodictyoptera of Palzozoic times than to the modern Blattariæ ; and yet we _ can so completely trace in Mesozoic times the transition from the Palzoblattarie to the Blattarie that no reasonable doubt can exist as to their descent, the one from the other. 3. The ordinal distinction which is now found in the wing structure of modern insects did not exist in Paleozoic insects, but a common simple type of neuration which barely admitted of family division. It will appear from this that, by a sort of principle of family continuity, we may recognize in the Palzeozoic insects a tendency toward a differentiation in ordinal characters sufficient to enable us in an ex post facto fashion to distinguish between orthopteroid, neuropteroid, etc., Palaeodictyoptera. when we look at the insects of later formations, we find types of every one of the existing orders of insects—speaking of these orders in their broadest sense, as we have everywhere done in ae ema —we find every one fully developed in the Jurassic pe 878 General Notes. (September, We find then that the entire change from the generalized hex- apod to the ordinally specialized hexapod was made in the inter- val between the close of the Paleozoic period and the middle, we may say, of the Mesozoic. These significant changes were ushered in with the dawn of the Mesozoic period, and the Tri- assic rocks become naturally (together with the Silurian) the most important, the expectant ground of the student of palzeon- ology. Hitherto for fifty years the Carboniferous period has claimed this interest as its birthright. It would then appear that the geological history of winged insects, so far as we know from present indications, may be summed up in a very few words. Appearing in the Silurian period, insects @ontinued throughout Palaeozoic times as a gener- alized form of Heterometabola which, tor convenience, we have called Palzodictyoptera, and which had the front wings as well as the hind wings membranous. On the advent of Mesozoic times a great differentiation took place, and before its middle all of the orders, both of Hetero- metabola and Metabola were fully developed in all their essential ` features as they exist to-day, the more highly organized Metabola at first in feeble numbers, but to-day, and even in Tertiary times, as the prevailing types. The Metabola have from the first retained the membranous character of the front wings, while in most of the Heterometabola, which were more closely and directly connected with Palzeozoic types, the front wings were, even in Mesozoic times, more or less completely differentiated from the hind wings as a sort of protective covering to the latter, and these became the principal organs of flight. Garman on Dipymopus.—Mr. Samuel Garman has published a description! of the shark Chlamydoselachus anguineus Garm., an introduced into his paper some comments on my paper? on the extinct shark Didymodus, which has been found in the beds of Permian age in Texas. Mr. Garman’s comments are in the form of a criticism which denies the existence of some of the lead- ing points of structure of the skull which I have pointed out. The surprise which these criticisms occasion increases when it is understood that they are derived “ from a study of the illustra- tions,” and not of the specimens themselves. And Mr. Garman appeals to “a comparison with the plate in the Proceedings” (of the American Philosophical Society) to “show whether they can be justified” (p. 29). To utter the sweeping conclusions reached by Mr. Garman on such a basis as this, is, to say the least, haz- ardous ; and it is a comparatively easy task to show that they are __ Wrong, by reference to the specimens themselves.

I now add that most of them were in my possession, and were objects of frequent mete eas by me, for five or six years before my publication in aanry : On p. 29 of his brochure, Mr. Garman sa “3. The skull is unsegmented ; the lines of segmentation, so- called, sais partly accidentals which are not alike on the two sides of the skull.’ To this it must be replied that the lines of segmentation cer- tainly exist, and that they are alike on the two sides of the skull “6. The Fig. 4 of the plate should be reversed in direction, the prolonged anterior portion in the figure should be turned back- wards from the interorbital region, thus bringing what in the fig- ure serve as orbits behind the postorbital processes. ave several perfect skulls of this species, including the one represented in ig. I, where the characters are readily seen, the supposition of Mr. Garman that I have reversed the specimen represented in Fig. 4 is simply curious; and as he derives his in- formation from a plate, one is also surprised at the lack of caution exhibited i in making the assertion e Ichthyotomi, as based on these skulls, have not been separated from the Selac The suborder Ichthyotomi was thus defined in my paper (p. 581): “ A basioccipital bone and condyle. Occipital ? pterotic and frontal bones distinct. Supraorbital (or nasal) bones present,” r. Garman gets over this definition by denying the existence of the segmentation, which, as we have seen, nevertheless exists ; and by ignoring the presence of the basioccipital bone and condyle. This would indeed be the muzzle of the skull, were the direction of Fig. 4 reversed, as proposed by Mr. Garman. As the characters above given are proven to exist, I must still regard the genus Didymodus as presenting a type of skull quite different m the true Selachii. I now add a few comments on other points in Mr. Garman’s ee On p. 21 of his essay Mr. Garman gives five references to the publications where he claims that I have called the Chlamydoselachus anguineus, Didymodus anguineus.” I have, however, never proposed or used this name at the places cited, or elsewhere. On p. 28 it is stated that I have never published my conclusion that these two genera are distinct. This w. done in the AMERICAN NATURALIST, 1885, pp. 236-7. F og Vaia a new name is proposed as a substitute for Didymodus (p. 30), because the latter is supposed to have became a’synomyme in another connection. Were this the fact, I should still retain as unused the name Didymodus, by which the form is now known ; but as it has not yet been positively shown to be distinct from some of the various genera of this group already proposed, the action of Mr. Garman is at least premature—Z. D. Cope. 880 General Notes. | September, ON THE ANTHRACARID&, A FAMILY OF CARBONIFEROUS MACRU- ROUS DECAPOD CRUSTACEA, ALLIED TO THE Eryonip&.'—Havin been kindly favored by Messrs. R. D. Lacoe and J. C. Carr with the opportunity of examining their collections of nodules from Mazon creek, containing Anthrapalemon gracilis Meek and Worthen, I have been able to discover some features probably not shown in the specimens examined by those paleontologists. The newly observed characters are the carapace with its rostrum, showing that the American species in these respects closely resembles the European ones figured by Salter, the founder of the genus. Moreover, specimens show the entire thoracic legs, while the antennz of both pairs were almost entirely shown. The fact that the first pair of thoracic feet were scarcely larger than the succeeding pairs shows that Anthrapalemon cannot be placed in the Eryonidz, but should form the type of a distinct group of family rank, none of the existing Macrura having such small anterior legs. At the same time the Carboniferous Anthra- caridz were probably the forerunners or ancestors of the Meso- zoic and later Eryonidz e genus Anthrapalemon, a Carboniferous fossil, was first described by J. W. Salter in the Quarterly Journal of the Geo- logical Society of London, (XVII, 529, 1861). The name given to the fossils has, the author remarks, “only a general significa- tion, and is not intended to indicate.a a relation to Palæmon. Minster, &. * * * It is broader than the general form of the Astacidz, or than Glyph and its Liassic allies, but much narrower than Eryon.” Salter’s type species is Anthrapalemon grossarti Salter. With this species the American A. gracilis is congeneric. A closely allied English form of A. dubius Prest- wich, is referred by Mr. Salter to the subgenus Palæocarabus, a name less fitting than Anthrapalemon. The telson, unlike that of any other macruran, fossil or recent, so far as I am aware, is differentiated into three portions: the basal, central piece is some- what polygonal, a little longer than broad; it is separated by a inct suture from a small triangular terminal piece which forms the apex of the telson. Between the outer half of the entire telson is a large broad lobe which is fringed with sete. At rst I ed it as a subdivision of the inner lobe of the last uropoda _ or abdominal feet, but no instance among the Decapoda is known to us in which thedast pair of uropoda have more than two lobes or divisions, and I have therefore been inclined to associate the _ innermost of the three setiferous lobes with the telson, and to regar | the telson «co mig into two median and two lateral lobu- : Whether the two lobes belong with esa ea or eas pye will leave for the present an open quest Read before the National Academy of Sciences, April, 1885. 1885.] Geology and Paleontology. 881 The only group in existence in which the telson is so remarkably differentiated is the Galatheide. In Munida the telson is divided by sutures into four pieces, the two terminal ones lobed and edged with setæ of the same size as those of the uropoda. In Eumunida of Smith the telson is “ short and broad, more or less membran- aceous, and divided by a transverse articulation, so that the distal part may be folded beneath the basal part.” In Anoplotus politus, like the foregoing a deep-sea galatheid, the telson is stif- fened by eight distinct calcified plates, a broad median basal plate, with a small one on either side at the base of the uropod anda small median one behind it and between a pair of broad lateral plates, still behind which there is a second pair which meet in the middle line and forms the tips and lateral angles. From the nature of the differentiation of the telson in the Gala- theidz I am inclined to believe, from what I have observed in the specimens before me, that the telson of Anthrapalamon is sub divided in nearly the same manner. If so we cannot refer the genus to the Eryonidz, and we would therefore regard it as the type of a distinct family which may thus be briefly characterized: Family Anthracaride: Body broad and somewhat flattened, in general appearance like the Eryonidz, but with the first pair of thoracic legs no larger than the four succeeding pairs; carapace with a long acute rostrum, with lateral spines on the anterior half, the telson differentiated into two median pieces, with two lateral broad rounded membranaceous lobes, fringed like the uro- poda with large sete. In anticipating the differentiated telson of the anomurous Gal- atheidz, this eryon-like shrimp is not an exception to the rule prevailing in the old-fashioned Carboniferous forms, which seem, in most cases, to be synthetic or ancestral types. The Eryonide, which began to exist in the Mesozoic age, have persisted to the present time, being represented by certain deep-sea forms, 2. e., Willemcesia and Pentacheles; on the other hand the Anthracari- dz appear to have become extinct at the end of the Palzozoic age, and the question naturally arises: Did they stand in an an- cestral relation to the Mesozoic and modern Eryonidz ? Appear- ances certainly indicate that the Eryonide, and perhaps the Asta- cidæ, may have descended from a group at least closely allied to the Anthracaride.—A. S. Fackard. Tue GeorocicaL History or New Zearanp.—Capt. F. W. Hutton, in an article upon the origin of the fanna and flora of New Zealand (Ann. and Mag. Natural History, February, 1885) arrives at the following conclusions: New Zealand, which for- merly existed as the southern part of a continent extending through Australia to India, was isolated from Australia to- ward the close of the Jurassic period, but was attached to a South Pacific continent and received a stream of immigrants 882 General Notes. [September, from the north. None arrived from the south because Fuegia was not then in existence. In the Upper Cretaceous the land shrank to a size considerably smaller than at present. In the Eocene, elevation took place, and New Zealand extended out- wards in all directions, but remained isolated. Plants and ani- mals came in both from the north and from the south. In the Oligocene and Miocene periods New Zealand was, except for a short interval, a cluster of islands, but was upraised once more, and obtained more immigrants from north and south during the Pliocene, after which subsidence occurred, and the land through- out the South island and southern half of the North island sank considerably below its present level, to be again elevated during the Pleistocene. GEoLoGICAL News, — ¥urassic.—M. Cotteau has studied more than 500 Echini from the Jurassic of France. The Jurassic seas, not very deep, with broken shores, numerous isles and many ex- tensive coral reefs, presented conditions eminently favorable for the existence of Echini. The evolution of the fifty genera de- scribed by M. Cotteau is of great interest. Some are special to the beds they occur in, and nothing in the beds above recalls their existence, while others have a curious persistence. Cidaris has subsisted from the Trias to the present day.

It is usually a red clayey sandstone, passing into a fragmentary conglomerate which unites it to the Vosgian below. ary and Quaternary—The British Eocene land Mollusca are treated of by J. S.

B. Scott (Science, 1835, 420) from an almost perfect skeleton found in Warren county, N. J. It was a very large animal, with large head, short neck and trunk, legs much longer than those of the great Irish deer, and antlers which were palmated, though less so than in the moose. There is a bezant antler and a posterior tine given off from the beam opposite to it. The two tines are connected by a flaring process of bone which descends below the level of the eye. The pre- maxillze are stag-like, and join the nasals, which are much longer than in the moose. The nostrils were smaller, and there was evidently no such a proboscis-like snout as in the moose. Cer- valces agrees with the moose in having the lower ends of the lat- eral metacarpals present, and on the whole is more like Alces than it is like Cervus. Professor Owen (Trans. Zool. Soc.

It encloses few minerals compared with other sands; quartz is most common, next monazite in yel- low and red crystals and zircon in brown to white, but seldom violet crystals; while staurolite, almandine, corundum and vari- ous iron ores are rarer. This is the first occasion in which corun- _ dum has been found in diamond beds, while tourmaline and other characteristic minerals are wanting. Mr. D. Pidgeon (Quart. Jour. Geol. Soc.) gives an account of some recent discoveries in the submerged forest of Torbay, Eng., and maintains, contrary to received opinion, that “while some of the so-called peat-beds VOL, XIX.—NO, Ix, 58 884 General Notes. [September, of the forest are not older than Roman times, the clays in which the forest is rooted are either coéval with or younger than the bronze age in Britain.” In December, 1883, the sea tore away the beach so as to expose this clay, at the junction of which with the Trias were found hearths of trap rock with bits of pottery, grindstones, glass, tin, slag and ingots of copper, leading to the conclusion that tin was smelted and bronze made prior to the deposition of the forest clay upon the surface of the Trias rock. Submergence need not be predicated, the damming back of the sea and the growth of trees below high-water mark behind the - damı furnish a probable explanation of the phenomena. MINERALOGY AND PETROGRAPHY.' AMPHIBOLE-ANTHOPHYLLITE FROM Mr. WASHINGTON, BALTI- MORE COUNTY.—A light-gray or brownish colored mineral, with a bronzy luster, occurs in considerable quantity as a gangue of the chalcopyrite ore which is mined a short distance north-west of the village of Mt. Washington, Baltimore county, Md. It is most frequently found in thin blade-like individuals varying much in size and with only faint indications of crystal planes. Such During the past fall blades of unusual size (10™ X 2°) were found, which had the planes æ Pz and æ P of the prismatic zone well developed. The angle between the planes of the prism (124° 30’) placed the hornblendic nature of the mineral beyon a doubt. The great purity and transparency of some of the material seemed to invite a chemital and optical examination which was accordingly undertaken by Mr. C. S. Palmer, of the _ chemical laboratory of the Johns Hopkins University. Some specimens of a reddish-brown color were translucent—almost transparent—though 2™™ in thickness. In these the usual fibrous structure parallel to the vertical axis was hardly noticeable, but a parting parallel to a very flat clinodome was quite pronounced, A chemical analysis of this freshest and most homogeneous material gave the following results : SiO, Al,0, FeO, FeO CaO MgO NaO K,O _ total $7.28 .,0.75 1.73 5.64 tr. 21.70 2.80 99 This will be at once recognized as the composition of a typical =~ anthophyllite.

This fact is of interest in con- nection with the observations of Des Cloizeaux on an exactly sim- ilar mineral from Königsberg and Greenland, for which he first pro- posed the name amphibole-anthophyllite.’. Groth has remarked that a considerable proportion of the minerals commonly called anthophyllite are probably monoclinic in their crystallization.

Rosenbusch! of Heidelberg, has recently made the most interesting observation that the morpho- logical no less than the optical characters of the mineral leucite can be brought into full accord with the regular system bya sufficient increase of temperature. It is well known that this mineral was regarded as the very type of an isometric icosatetra- hedron until vom Rath showed that considerable variation from the calculated angles as well as frequent twinning lamellz paral- lel the face O necessitated the assumption of a tetragonal sym- metry. The double refraction of this substance was also a point in favor of this view. The recent studies of Klein, Merian and Penfield have, however, shown that above a certain temperature leucite, like boracite, becomes altogether isotropic and now Rosen- busch finds that by the same means the twinning lamelle, ordi- narily visible as a system of fine striations, may likewise be made to disappear. A crystal upon which these were unusually dis- tinct was brought in focus under the microscope by reflected light in such a manner that the main face appeared bright while the lamella were in the shadow. Heat was now gradually applied and the most remarkable effect observed. A kind of un- dulatory motion was noticed and whole groups of lamella would disappear at one point and reappear at another, until finally, at the requisite temperature, all were gone and the face was seen to be quite uniform and even. Upon cooling the lamellæ returned but in a different position from that which the original ones occu- pied. So great was the molecular disturbance here produced, that after some repetitions of the experiment on the same crystal it fell to pieces. The supposition is made that leucite crystallizes in the regular system at high temperatures, and in some other unknown system at ordinary temperatures. The effort of the molecules to suit their arrangement to the altered. conditions produces a ten- sion which finds relief in the formation of secondary twinning lamellz parallel to the slipping plane (“ gleitflache ”), which in this case is ġo O: en the temperature is raised this tension 1s of course removed. The attempt will be made by the same inves- tigator to measure a crystal of leucite on a reflection goniometer at the temperature necessary for the obliteration of the twinning — lamella, when it is expected that the interfacial angles will agree „perfectly with the regular symmetry. BOTANY.” _ THe Axsunpance or Asu Rust.—In Eastern Nebraska, this ‘year has been remarkable for the great abundance of the ash rust ~ '(Aicidium fraxin’) upon the leaves, petioles and twigs of the green ash.

I. * Edited by ProrEssor CHARLES E, Bessey, Lincoln, Nebraska, 1885. ] Botany. 887 twenty of the characteristic spots, varfing from a tenth to a quar- ter of an inch in diameter. The petioles and partial petioles were frequently greatly distorted and enlarged, and in many cases the young twigs were swollen out into rounded nut-like growths which were covered with the tubular A®cidia. The injury produced by this rust in Lincoln was quite consid- erable, as green ash trees have been very largely planted along the streets for shade and ornament. These planted trees appear to have suffered more than the native ones along the streams, although the latter were by no means free from the parasite. I have as yet been unable to obtain any clue to the further de- velopment of the ash rust. One would look for a correspondingly great growth of red and black rust upon some of the plants of this region, but so far I have not observed any indication that such is the case.— Charles E. Bessey. THE FERTILIZATION OF THE WiLD BEAN (Phaseolus diversi- folius)—The flowers (Fig. 1) of the wild bean whén fresh are of a pretty rose-purple color, turning to a sort of dirty flesh color in fading. This change of color occurs at a time when insect visits are no longer necessary to the flower and no doubt serves to in- form the insect that it has no food to offer. The two wings are free from the keel but lie close to it; they furnish an alighting place Da 2 Fig. 2. Fic.—Flower of wild bean, seen somewhat from below. Fic. 2.—Keel and wings.

The keel itself the form of a vertically placed lens at its base, narrowing above into a narrow tube, which encloses both stamens and styles ` (Fig. 3). The anthers lie about the hairy end of the style and their pollen upon it. After this has escaped the free ends of the filaments shrivel up and allow the somewhat freer movement of the style. The anthers never leave the keel. Nine of the stamens are united by their filaments, but the tenth is free, In 888 General Notes. [September, their natural state both stafhnens and style are included by the keel and lie along the lower portion of the dilated part of the keel (Fig. 4). When a bee visits the flower it alights upon the wings on the left side of the keel. In its struggles to get at the honey, it pushes down the wings, these carry with them the keel, and their combined motion forces out the hairy end of the style, while the peculiar curvature of the keel directs its stigma to the side and back of the bee (Figs.5 and 1). In this act the stamens and style are in reality passive. They lie at first along the bottom of the keel, the depression of the keel pulls it away from the sta- mens and draws its tube down from the style, the small opening at its end forbidding the extrusion of the stamens. The pollen collected on the hairs of the style is left on the back of the bee and the stigma receives fresh pollen from some other flower which had been left on the back of the insect during some pre- vious visit. As soon as the bee leaves the flower the parts again resume their normal position. The mechanism of the flower is similar to that of h. vulgaris, but lacks the double spiral of the keel.— Aug. F. Foerste, Granville, Ohio, THE Movement OF PROTOPLASM IN THE STYLES OF INDIAN Corn.—It will not be too late when this appears in print for stu- dents in botanical laboratories to study the movement of the protoplasm in the long styles (“silks”) of the Indian corn. By ing a young style from an ear which has been kept in a warm place for an hour or so, clipping off a piece a couple of inches in length and carefully mounting it in water under a large cover- glass, there will be no difficulty in seeing a great deal of activity in the protoplasm. Care must of course be taken to have the style lie flat, remembering that it is not cylindrical in shape, but somewhat ribbon-shaped. The cells are much elongated and the walls are so transparent that with careful focusing their contents may be seen, even in the interior parts of the style. The protoplasm is sufficiently granular to be easily seen. It moves along the side of the cell in a strong steady stream, occa- sionally heaping up a great mass, which is eventually pushed on- ward by the current. As an easily obtained and instructive ex- ample of protoplasmic activity I know of nothing which is supe- rior to such a specimen.— Charles E.

This bacterium winters in the bulb scales, and increases in the spring _to slimy yellow masses which destroy the tissues and eventually kill the plant. The priority of demonstrating parasitic bacteria in Plants belongs, however, to an American.

Burrill, of Illinois, presented a- paper before the American Association for the Advancement of Science demon- disease known as “ pear blight,” which attacks pomaceous trees, and that the disease may be transmitted from tree to tree by inoculation. Since then the bacteria have been isolated and cul- tivated in artificial media, and the statements of the original paper fully confirmed. Americans should have credit for what little original work they do accomplish in bacteriology.—/. C. Arthur, in Botanical Gazette. ORK FOR THE BOTANICAL CLUB OF THE A. A. A. S.—This organization, with its large yearly attendance, may Well undertake some work which has been long neglected in this country. We _do not forget that the principal object of its founders was to bring the botanists together for social purposes, and are rejoiced to know that in this respect it has accomplished much. Many of the lonely botanists living in remote parts of the country have been gladdened and encouraged by meeting their fellows and consulting upon means and methods. This result is in itself a justification of the existence of the club. ut this should not be all. At every annual meeting some progress should be made in the effort to bring about concerted action among the botanists of the country with regard to many matters. We will venture to suggest here some things which might well occupy a part of the time of the club. 1. In view of the rapid increase in what may be termed popu- lar cryptogamic botany, it is desirable that there should be uni- formity in the use of English names of the species and groups. For example, to what group shall we apply the name of the mildews? or the blights? 2. Cannot the botanists do somewhat to bring about greater uniformity in the pronunciation of botanical names and terms? t this is needed requires no further demonstration than that afforded by a single session of the club. We believe that the time is not far distant when botanists must listen to our Latin lars, and take steps which shall lead to a pronunciation in conformity with what is now regarded as the best Latin usage. 3. The question of the publication of botanical papers (aside 890 General Notes, [September, with profit, we apprehend, to the botanists and also to the Na- tional Herbarium.— Charles E, Bessey. BoranicaL News.—The subject of bacteriology received espe- cial attention in the July number of the Botanical Gazette, there being no less than a dozen notes and notelets devoted to it, be- sides four reviews of books upon the same subject. Clara E. Cummings, of Wellesley, Mass., has prepared a neat catalogue ot the Musci and Hepatic of North America north of Mexico, which will prove useful to botanists who collect specimens in ese classes of plants. The arrangement of the mosses is based upon Lesquereux and James’ Manual of Mosses, and that of the liverworts upon Underwood’s Catalogue of the North American Hepatice. There are enumerated 888 species of mosses and 231 of liverworts, besides many varieties. Copies may be procured of the author for thirty-five cents each.

A NEW SPECIES OF CRAMBUS INJURING Corn Roots.—On the 7th of June, 1883, my assistant, Mr. Webster, who had been detailed to study the work of the black-headed grass maggot in corn fields, brought to the office some supposed cutworms, bristly reddish larvæ, which he had found gnawing the roots of corn below the surface, in fields in McLean county, on both old and new ground. They were not seen again during this season, but on the roth May of the present year I received the same species from Mr. E. Gastman, superintendent of public schools at Decatur, with the information that they had. been sent him from Harristown by a armer who reported that they were doing serious damage to the roots of his young corn. On the 27th May, I visited Dwight for the purpose of searching the fields of Mr. Mills from which the web worm had been sent me. The corn in this field was injured most in patches. Over one area of about one-fourth of an acre, many hills were missing, and fully one-third of those remaining were damaged, with a plant occasionally killed. Upon digging into the affected hills the cat- ` erpillars were found just beneath the surface, sometimes as many as five or six in a hill, each in a retreat formed by loosely webb- ing together a mass of dirt irregularly cylindrical in shape, one and one-half to two inches long, and about one-half an inch in diameter. The worm was found ina silk-lined tube within this mass (the tube not always perfectly constructed), which in some cases opened at the surface, its presence being indicated by a circular opening about the size of wheat straw, in the earth next a stalk of corn. The first attack upon the plant was made by gnawing the outer surface beneath the ground and above the roots. Occasionally the stalk was completely severed, as by a cutworm, but usually not, the larve showing rather a disposition to work upwards, eating a superficial furrow or burrowing lengthwise along the center of estem. In other parts_of the field, only here and there a stalk was attacked. The foliage was also frequently eaten, the lower leaf first and then the upper ones, the larva evidently leaving its. burrow for this purpose, The tips of the leaves were eaten off, or irregular elongate holes were eaten through them—probably at night, as I have never seen the larva abroad by day. Where the corn was largest, webbed masses of dirt were frequently found which contained no larvæ, a fact which I was at first inclined to Suppose indicated that the insect inhabiting them had transformed, €specially as the larve found were of quite uniform size and apparently full grown. I failed to find a single pupa, however ; and as our breeding experiments did not yield the insect for more a month, it seems more likely that these empty webs had + w 892 General Notes, [September, been abandoned by worms which had gone in search of younger stalks. On the 7th June, after several hours of careful search in corn- fields near Lexington, McKean county, where I selected by pref» erence the least thrifty fields, I found no living larvæ, and but a single mass of webbed dirt at the base of a stalk precisely similar to those formed by the web worm, the hill containing it having been evidently damaged some time before. A number of the larve were brought to the office and placed in earth in-a breeding cage on the 28th May. On the 14th June those in the breeding cage were transferred to fresh corn, Many of them were dead, but nine active specimens remained. On the 30th the corn was renewed and another search was made. No larvz were found and but two living pupz. A single imperfect moth was released from the earth in which it had completed its transformations, but it was not able to expand its wings and could not be determined. One of the other pupe was unfortunately crushed by accident, and the other was badly infested by mites which clung closely to its crust about the head with inserted beaks. These were carefully picked away, and this sole remain- ing pupa was returned to thoroughly calcined earth to complete its transformation. On the 22d July it emerged as a small gray moth, evidently belonging to the family Pyralide. From Professor C. H. Fernald, to whom I referred the speci- men, I learned that it was a ‘species of Crambus, new to him and probably undescribed. It is described as Crambus zeéllus Fer- nald, and is kńown to inhabit Maine, Penna., W. Va., Illinois and Missouri. On the 3d July Mr. Mill, of Dwight, wrote me that the larve had almost entirely disappeared from the corn fields, and that the season had been so favorable to the crop that no perceptible damage had finally ape with the exception of the loss of a few hills here and ther e small size of the individuals observed earliest in the season perhaps makes it possible that they came from the egg last spring ; and the brood represented in our collections must have complete its development by the end of July.

MIMICRY OF A DRAGON-FLY BY A SUMATRAN BUTTERFLY.—By the margin of a small stream I caught Leptocircus virescens, which derives protection from mimicing the habits and appearance of a dragon-fly, in a crowd of which it-is often to be found. In form it reminded me of the European genus Nemoptera. It flits over the top of the water fluttering its tails, jerking up and down just ‘as dragon-flies do when flicking the water with the tip of their abdomens.

This increase in area of distribution is to be accounted for from the fact that the species is two-brooded, and that the second or spring brood made its presence felt in many counties in which the first brood was not sufficiently numerous to attract attention. A new de- structive insect is the web-worm, a pyralid caterpillar whose rav- ages have been thus far confined to Kansas, and has been inju- rious to corn and potatoes. It is said to occur in Texas, where it is known as the cotton-worm. ZOOLOGY. THE SKELETON OF THE MarsIPOBRANCHI.—Mr. W. Parker con-. tributes to the Transactions of the Royal Society, 1883, a study of the skeleton of the marsipobranchs. At the outset he states that the hag and Bdellostoma are a greatly modified and arrested sand lance or Ammocete, and that a larval frog is also a marsi- pobranch. He remarks: I feel satisfied that the Anura have only gradually become metamorphosed, and I doubt whether a% the larve of Pseudis undergo that change, even now.” The adult lamprey, like the tadpole, is truly suctorial, but the mouths of the Ammocete or larval lamprey, and of the Myxinoids, are not modified into a circular sucking ring, but remain as a small hooded opening fringed with short barbels. All the cartilage of the hag fish is cephalic, for even the far- thest rudiment of the dorsal part of the branchial basket 1s supplied by the vagus nerve, and the spinal region is only sup- ported by membrane or fibrous tissue. No cartilaginous rudi- ments of vertebral arches can be found.

Tne Pine Mouse 1n NortHern New YorkK.—On the 13th of June, 1884, at my home in Lewis county, New York, I caught a female pine mouse (Arvicola pinetorum LeConte). It was taken in a trap baited with beechnuts and set for the red-backed wood mouse (Evotomys rutilus Gapperi) at the roots of a maple in the border of a hard-wood forest. This species has not been pre- viously recorded from so far north in the Eastern States, Massa- chusetts having been given as the limit of its northern range. Its rarity appears from the fact that this is the only individual ever Procured here, while of the common meadow mouse (Arvicola riparius) I have taken several hundred specimens. _* This was suspected by Professor Baird nearly thirty years ago, for he said: “I am not prepared to admit the Scalops eneus of Mr, Cassin as distinct from S. fown- 2.

A NEW GENUS AND SPECIES OF SHREW.—In the Transactions of the Linnzan Society of New York, Dr. C. Hart Merriam describes and figures a shrew of more than ordinary interest captured by Captain Bendire near Fort Klamath. It is one of the largest of the shrews, is the type of a new genus, and is called Alophyrax bendiru. Bendire’s shrew differs from all existing genera in exter- nal, cranial and dental characters. It has affinities with both Sorex and Neosorex, and is in some respects intermediate between them, though in some respects it passes Neosorex in the direction away from Sorex. It also possesses characters of its own not found in either of these genera. Dr. Merriam thinks that it in common with Neosorex was early differentiated from a group of thirty- two toothed shrews of which the genus Sorex contains the near- living allies. “ Having abandoned a fossorial for, in the one case a natatcry, in the other a paludal habit, Neosorex and Atophyrax doubtless began to diverge in the same direction, their distinctive features having been developed and intensified as their peculiari- ties of habit became fixed—each retaining in different degrees of modification certain characteristics of the original stock.” HARELDA GLACIALIS AT NEw Or LeEANS.—An old male in win- ter plumage was shot on Lake Catherine, a salt water bay a short distance from the city, on Feb. 28th, 1885.

Frobisher’s account of the Eskimo themselves is, so far as we know, the first extant, and is full and characteristic. After describing the natives he goes on to say: “They frank or keepe certaine dogs not much much vnlike wolues, which they yoke togither, as we do oxen and horses, to a sled or traile: and so carry their necessaries over the yce and snow from place to place: as the captive, whom we haue, made perfect signes, And when those dogs are not apt for the same vse: or when with hunger they are constrained for lack of other vituals, they eate them’ so that they are as pec for them in respect of their bignesse, as our oxen are for v Regarding the Eko dog, Richardson remarks in his Fauna Boreali-Americana, p. 75: “The great resemblance which the domestic dogs of the aboriginal tribes of America bear to the wolves of the same country, was remarked by the earliest set- tlers from Europe (Smith’s Virginia), and has induced some nat- uralists of much observation to consider them to be nearly half- tamed wolves (Kalm). Without entering at all into the question of the origin of the domestic dog, I may state that the resem- blance between the wolves and the dogs of those Indian nations, who still preserve their ancient mode of life, continues to be very remarkable, and it is nowhere more so, than at the very northern extremity of the continent, the Esquimaux dogs being not only extremely like the gray wolves of the Arctic circle, in form and color, but also nearly equaling them in size. The ‘dog has gen- erally a shorter tail than the wolf, and carries it more frequently curled over the hip, but the latter practice is not totally unknown to the wolf. *-* * I have, however, seen a family of wolves playing together, occasionally carry their tail curled upwards.” e Hare Indian dog is also supposed to be a domesticated race of the prairie dog, as shown by tap following extract from Richardson’ s Fauna Boreali-American Great Bear lake and the banks of the Mackenzie. Itis used by them solely in the chase, being too small to be useful as a beast of burden or draught.” Itis smaller than the prairie wolf. “On com- paring live specimens I could detect no marked difference in form (except the smallness of its cranium), nor in fineness of the fur, 1 The second voyage of Master Martin Frobisher, 1577. se by Master Dio- nise Settle, Hakluyt, Vol. 111, new edition, London, 1810, p. 6 898 General Notes. [September, and arrangement of its spots of color. * * * It in fact, bears the same relation to the prairie wolf that the Esquimaux dog does to the great gray wolf.” Another variety of Indian dog is Richardson’s Canis familiaris var. D. novecaledonie, Carrier Indian dog. The Attnah or Car- rier Indians of New Caledonia possess a variety of dog which differs from the other northern races. “It was the size of a large turnspit dog and had somewhat of the same form of body; but it had straight legs, and its erect ears gave it a different physiog- nomy.” The spitz dog, Mr. J. A. Allen informs us, is with little doubt a domesticated subarctic variety of the prairie wolf. Sir John Richardson in the Appendix to Back’s Narrative, Paris, 1836, p. 256, remarks: “ Indeed, the wolves and the domes- tic dogs of the fur countries are so like each other, that it is not . easy to distinguish them ata small distance; the want of strength and courage of the former being the principal difference. The offspring of the wolf and Indian dog are prolific, and are prized by the voyagers as beasts of draught, being stronger than the ordinary dog.” i The origin of the ordinary Indian dog of North America is obscure, but Richardson, who names it Canis familiaris var. C. canadensis, North American dog, throws much light on its origin : “ By the above title I wish to designate the kind of dog which is most generally cultivated by the native tribes of Canada, and the Hudson Bay countries. Itis intermediate in size and form between the two preceding varieties, and by those who consider the domestic races of dog to be derived from wild animals, this might be termed the offspring of a cross between the prairie and gray wolves. * * * The fur of the North American dog is simi- lar to that of the Eskimaux breed, and of the wolves. The pre- vailing colors are black and gray, mixed with white. Some of them are entirely black. * * *” H 1885. ] Lvdlogy. 899 followed them at the heeles ; but wee retired vnto our boate with- out any hurt at all received.” (The voyage of the ship called the Marigold of M. Hill of Redrise vnto Cape Breton and beyond to the latitude of 44 degrees and an half, 1593, written by Richard Fisher Master Hilles man of Redriffe. Hacluyt, 111, 239.) It is probably this variety, the bones of which have been found by Dr. J. Wyman, in the shell heaps of Casco bay, Maine. “The presence of the bones of the dog might be accounted for on the score of its being a domesticated animal, but the fact that they were not only found mingled with those of the edible kinds, but like them were broken up, suggests the probability of their having been used as food. We have not seen it mentioned, however, by any of the earlier writers, that such was the case along the coast, though it appears to have been otherwise with re- gard to some of the interior tribes, as the Hurons. With them, game being scarce, “ venison was a luxury found only at feasts, and dog flesh was in high esteem.” * * * A whole left half of the lower jaw of a wolf was found at Mount Desert, measur- ing 7.5 inches in length, making a strong contrast in size witha similar half from a dog found at Crouch’s cove. This was more _ curved, and had a length of a little less than five inches.” (AMER. Nar., 1, 576, Jan. 1868.) It is possible that the Newfoundland dog was indigenous on that island, and also an offshoot of the gray wolf, allied to the Eskimo, In their “ Newfoundland,” Messrs Hatton and Harvey Say that there are few fine specimens of the world-renowned “ Newfoundland dog” to be met with now in the island from which it derived its name. “ The origin of this fine breed is lost ound in Labrador, and specimens are also to be met with in Newfoundland,” Pp. 194-195. i Regar ding the dogs of the Mexican Indians, Nadaillac says in his Prehistoric America: “The European dog, our faithful com- VOL.

His place was very inadequately filled by the coyote,” or prairie wolf, which they art in captivity and had succeeded in taming to a certain exten i a recent visit to Mexico, not only along the railroads, but in the course of a stage ride of about five hundred miles through pro- vincial Mexico, from Saltillo to San Miguel, we were struck by the resemblance of the dogs to the coyote ; there can be little doubt but that they are the descendants of a race which sprang from the partly tamed coyote of the ancient Mexican Indians. At one village, Montezuma, we saw a hairless or Carib dog as we sup- posed it to be; similar dogs are sometimes seen in the United States. Finally that the domestic dog and gray as well as the prairie wolf will hybridize has been well established. ` Dr. Coues has observed hybrids between the coyote and domes- tic dog on the Upper Missouri (see the AMERICAN NATURALIST, 1873, p. 385). To this we may add our own observations made at Fort Claggett on the Upper Missouri in June, 1877. We then were much struck by the wolf-like appearance of the dogs about an encampment of Crow Indians, as well as the fort; they were of the size and color of the coyote, but less hairy and with a less bushy tail. They were much like those lately observed in Mex- ico, and I have never seen such dogs elsewhere. Their color was a whitish tawny, like that of the Eskimo dog. Confirmatory of these observations is the following note by J. L. Wortman in the report of the Geological Survey of Indiana for 1884: “ During extended travel in Western U.S. my experience has been the er: > that recorded by Dr. Coues. It is by no means uncomm o find mongrel dogs among many of the Western Indian thet notably among Umatillas, Bannocks, Sho- shones, Arrapahoes, Crows, Sioux, which to one familiar with the orth physiognomy and habits of the coyote, have every appear- of blood relationship, if not, in many cases, this animal itself ee a fate of semi-domestication. The free inter-breeding of these animals, with a perfectly fertile product, has been so often repeated to me by thoroughly reliable authorities and whose opportunities for observation were ample, that I feel perfectly willing to accept Dr. Coues’ statemen To these statements may be added. that of Mr. Milton P. ‘Certain kinds of dogs were, however, eceip age in America.

I have seen several of them, sired both by dogs and wolves, and all I have seen have resembled wolves rather than dogs.” It is to be hoped that our mammalogists may col- lect and examine this subject, particularly the skulls and skins of numerous specimens both of dogs and wolves and of the hybrids between them. Farther observations are also needed as to the fertility of the hybrids—A. S. Packard. ZOOLOGICAL News.—General—-MM. G. Pouchet and T. de Guerne have examined the organisms taken by net in the Baltic, in 1884, by the Prince of Monaco. The region fished over ex- tended from 54° 590’ N. lat., at 14° 48’ long. W. of Paris, to the end of the Gulf of Finland. It seems that the pelagic fauna of this gulf resembles that of the great lakes of Europe, as made known by Forel, Lilljeborg, and others. Certain species of Cladocera are very common, and, as in the lakes, are attacked by parasitic cryptogams. Numerous Infusoria and rotifers of the enus Anuræa augment the resemblance to the fauna ef the Scandinavian lakes. The central basin of the Baltic offers char- acters transitional between those of fresh and salt water. Sponges. —Mr. H. I. Carter (Ann. and Mag. Nat. Hist, Febru- ary, March and April, 1885), describes numerous new species of sponges from the neighborhood of Port Philip Heads, South Australia, and also contributes a note upon the mode of circula- tion in the Spongida. Celenterates—Professor Allman recently read before the innzan Society descriptions of thirty-eight new species of hy-: droids, belonging to twelve genera. The plumularian genus Podocladium is very remarkable, not onl by the possession of both fixed and movable nematophores, but by the fact that every hydrocladium is supported on a cylindrical jointed peduncle. Thuiaria heteromorpha combines upon one hydrophyton no less than three morphological types, yet Mr. Allman regards the generic position as determined by the one which most decidedly prevails in it. Mollusks—M. Lacaze Duthiers has instituted a comparison be- tween the ordinary slugs and the genus Testacella. Especially he has compared the nervous systems and traced out the homologies _ of the nerves. In the slug the rudimentary mantle is situated upon the back, while Testacella carries its small shell and under- lying mantle on the under side of its posterior extremity, yet the innervation of these parts is the same. The Testacella is not a vegetable eater, but searches for and devours worms by following them into their holes, and M. Lacaze Duthiers believes it to be a slug gradually altered and transmitting its altered characters by redity.—W, E. Hoyle (Ann. and Mag. Nat.

H. Cooke republishes, with additions and corrections, a list of the testaceous mollusks ob- tained by R. MacAndrew in the Gulf of Suez. Of nineteen species of Cypræa found, nine occur at the Sandwich islands, six in Japan, eight in Australia and five at Natal, and of seven species of Triton two are common to the Sandwich islands, two to Japan and one to Australia. Crustacea —E. J. Miers (Ann. and Mag. Nat. Hist., January, 1885) gives a synopsis of the species of Micippa and Paramicippa. He allows six species of the former genus (M. cristata, mascarenica, philyré, spinosa, curtispina, and thalia), all of which seem to be restricted to the shallower waters of the Indo-Pacific, yar — n the the littoral decapodous Crustacea of the Black sea. The num- ber of Pontic decapods has been increased by twenty, thus reach- ing forty-eight species. The author arrrives at some interesting conclusions as to genealogy. The nine different stages of the metamorphosis of Carcinus are, he says, a repetition of its gene- alogy ; all three species of Astacus found in the Ponto-caspian fauna are maritime forms which have immigrated into sweet -~ water, and even Astacus pachypus of the mountain lake Abrau is e remainder of a maritime fauna, so also Thelphusa, which has gigantic representatives in the South Caspian. Æriphia spinifrons and Carcinas menas reach a very large size on the shores of the Crimea and at Odessa. While most crabs reach their fullest de- velopment only in very salt and warm water, others reach the same size under reverse conditions. The decapods of the Sea of Azov have not yet been explored. Fishes —Professor Fritsch has been induced by the examina- tion of the peculiar flap-like appendages of Lophius to search for _ corresponding peculiarities in the nervous system, peculiarities which he soon discovered in the medulla oblongata. On the posterior side of the medulla, quite superficially situated, he found a group of huge ganglion-cells, such as had hitherto only been found in Malapterurus. While the latter fish had but two such cells, Lophius had a larger number. 1885.] Embryology. 903 Reptiles and Batrachians—G. A. Boulenger gives a list of thirty-one reptiles and sixteen batrachians from the province of Rio Grande do Sul, Brazil, collected by Dr. H. von Ihering. The new species are Enyalius theringii, and Liolemus occipitalis (Lacertilia), and Coronetta theringit. EMBRYOLOGY. ON THE AVAILABILITY OF EMBRYOLOGICAL CHARACTERS IN THE F o est major subdivision of the Endocyemate subphylum em- braces forms in which the ovum is invested by a zona radiata, external to which comes an additional investment of albuminous matter secreted by the oviduct, this albuminous envelope being usually in turn covered by a fibrous membrane immediately over- laid by a porous, more or less calcareous shell, also secreted by the oviduct. Chalazæ are often developed. The cleavage is par- tial, the germinal matter, as a rule, forms but an insignificant part of the whole ovum, and is aggregated at one pole of the latter as a blastodisk. The blastodermic vesicle is developed from the blastodisk by epiboly upon the vitelline mass, which is finally in- - cluded so as to occupy a ventral position in the vesicle. Devel- opment is at most viviparous only during the very earliest stages or while the ovum is passing through the oviducts, or more or less entirely oviparous, or quite ovoviparous. The allantois is greatly developed, but never associated in the development of a true placenta, though it is usually respiratory in function. Under this definition the three following groups seem to be appropriately included: a. Ova buried in the earth or sand by the parent, and left to be incubated by the heat of the sun. Some species ovovivipa- rous. Reptilia. : ő. Ova incubated by the parent in a nest specially constructed for the purpose. Aves. c. Ova incubated by parent in an abdominal marsupium or in a nest at the end of a burrow. Recently hatched young nour- ished by the parent for a time upon milk secreted by mammary glands. No functional uterus. Ornithodelphia. It may also be noted that with group å the distinctly warm- blooded series of the Chordata begins. The relatively high tem- P _rature of the body of the adult plays an important part in incu- “tion or in accelerating metabolism in the embryo. .The pre- c*ding three groups, on account of the many features of resem- “ance and reptilian traits possessed in common (group c being ! Edited by JoHN A Ryper, Smithsonian Institution, Washington, D. C. 904 General Notes. | September, phylum embraces the eutherian type, or the viviparous Mamma- lia, in which the ovum is invested only by a zona radiata. The ovum also becomes more or less covered over by reflections of the uterine epithelium, or processes from the surface of the ovum are received into furrows or pits of the mucous surface of the uterine cavity, in which embryonic development proceeds more or less nearly to completion, and where the developing embryo acquires nourishment after the manner of a parasitic organism. The cleavage of the egg is total, and leads to the formation of a hollow, rapidly-enlarging, blastodermic vesicle or blastula, in which no vitelline matter or deutoplasm lies free in the ventral pole or yolk sack. This group is characterized by its viviparity, the development of a placenta and the possession of a functional uterus; it has obviously descended from one of the preceding groups which had ova provided with a large yolk, the yolk hav- ing gradually atrophied or failed to develop as the peculiar vivip- arous mode of development became more and more pronounced. . a, The lowest division of the Eutheria would be separated from the highest, on embryological grounds, by the circumstance that the vascular system of the foetus is brought into relation with the maternal vessels by means of the vessels of the yolk sack (Owen, Osborn). Or by means of pseudopodal processes of the cells forming the yolk sack, Phascolarctos (Caldwell). Allantois more or less rudimentary. Didelphia. 6. In the highest division of the Eutheria the vascular system of the foetus is brought into relation with the maternal vessels by means of the allantois, which is concerned in forming a villous or spongy vascular mass known as the placenta. Monodelphia. In the present state of our knowledge it seems premature to i attempt a definition of the orders of the Monodelphia upon the -basis of placental characters alone, as the following scheme seems- to show. It is difficult, however, not to believe that the non- allantois invests the whole embryo. In this succession the orders of the Monodelphia will therefore be here arranged as nearly as possible : aa. Placenta non-deciduate, diffuse or cotyledonary. Cetacea, Sirenia, Ungulata. _ 66, Placenta non-deciduate, diffuse (Manis); or non-deciduate ? early zonary (Orycteropus); or non-deciduate, zonary (Dasypus vemcinctus) ; or deciduate discoidal (Dasypus sp., Cholcepus). a deciduate, zonary.

Rodentia, Insectivora, Chei- roptera, Primates. uch remains to be learned of the earliest stages of the forma- tion of the placenta, especially in the Primates. In Talpa, Heape has found a rudimentary “träger” or suspensor developed. In some of the Rodentia the embryonic mass is precociously invag- inated into the blastoccel, and the amniotic cavity is formed in the most extraordinary manner, or by a sort of vacuolization or accumulation of fluid (liquor amnii) in the midst of the mass of undifferentiated embryonic cells. This occurs in Mus, Arvicola and Cavia, according to Selenka. In these forms the blastodermic vesicle also becomes adherent to the uterine epithelium at a very early stage, and the suspensor is very markedly developed in the three forms mentioned. The precocious invagination of the un- differentiated embryonic mass of cells into the blastoccel leads, in the Rodentia, to an apparent inversion of the embryonic layers. These forms have therefore attained the most specialized mode of development known amongst Mammalia, so that, judged by the standard of embryology alone, they would rank higher than the Primates. The foregoing scheme illustrates in a very striking manner the way in which complication after complication has been added to the developing germ, starting with a simple blastula developed by total cleavage in Branchiostoma ; the-next step in the progress of embryonic specialization is that seen in the amphibian and mar- sipobranchian embryo, in which a distinct neurenteric canal is also developed, and in which the neurenteron is continued into the enteric cavity, which itself traverses the segmented vitelline mass longitudinally along its upper half. In the next grade of special- ization, or that represented by the Ichthyes of this arrangement, the vitellus remains unsegmented for a long time, and is practi- cally excluded from sharing in the formation of the enteric walls, but the embryo is sessile in the greater number of species em- braced in this series, and while only a portion of the blastodermic area leads to the differentiation of an embryo, no part of the ecto- last is ever so folded off to form provisional organs such as the go6 General Notes. | September, ` ever, there is a manifest tendency for that structure to increase rapidly in size owing to the imbibition of fluid with which the blastoccel becomes more and more distended, this increase in size at the same time being aided by the division of the cells entering into the formation of the walls of the blastoccel. The greater part of the walls of this vesicle are finally metamorphosed by a process of folding off and ingrowth of the embryo into the vesi- cle by invagination, into a respiratory apparatus and secondary system of envelopes, a portion of which also takes part more or less extensively in the absorption of pabulum from the surround- ing uterine surfaces which may be more or less completely re- flected around the embryo and its vesicle, to be finally cast off at . birth together with those parts of the vesicle derived from the ectoblast, which are also deciduous. The vesicle also tends, with a few exceptions, to thrust out hollow villi, which dip into pits in the uterine mucosa. ese may arise locally or all over the ves- icle, and reach their fullest development when the chorion has been formed, when the greater part of the surface of the vesicle acquires a shaggy covering of villi, into which vascular loops from the allantois are insinuated, over a restricted area internally or over its whole surface. These then become more or less com- pletely insinuated into vascular uterine crypts into the constitu- tion of which a decidua may or may not enter. t will, I think, be obvious to any one, that if an oviparous paratherian form were to have the eggs which it produces so modified as to lose the shell, yolk and albuminous and fibrous envelopes, leaving only the naked endocyemate ovum to be re- tained near the outlet of the oviduct, the wall of which would then become thickened so as to form a specialized uterine dilata- tion, the conditions for a realization of the eutherian mode o viviparous development would be present. In this way, no doubt, the peculiarly specialized mode of mammalian development arose. Objections may be urged against the position I have assigned to the Amphibia and Marsipobranchii as well as to the names given to the groups, and to the stress laid upon the physiological aspects of development and their importance not only in taxon- omy but also in tracing the mode of the evolution of particular grades of development. ; The form of the placenta seems to depend upon several factors: (1) The early or late attachment of the blastodermic vesicle to the 1885.] Fhysiology. 907 y vitellus, lead, in certain cases, to very remarkable modifications of embryonic development. The foregoing scheme deals more especially with the evolution of the various higher types of development, and if the way in which these have grown out of the lower ones has been made a little less obscure than hitherto, my object in writing this will have been attained. The manner in which placentation has been modi- fied is also a fruitful subject for farther investigation, not less so, in fact, than the question as to how the amnion arose. The facts of embryology tend to show that the amnion is the result, as stated above, of the gradual invagination of the embryo into the blasto- dermic vesicle. The invagination begins at the head end of the embryo ; the amnion, as is well known, always developing its first traces at ‘the cephalic end of the embryonic disk. It is also probable that the cavity of the false amnion is the homologue of the cleavage cavity of certain of the lower forms — ¥ohn A. Ryder. PHYSIOLOGY. A CONTRIBUTION TO THE KNOWLEDGE OF PeEpstn?.—Sundberg has hit upon a method for preparing pepsin, which gives results better than those obtained by Briicke’s method. . Calves’ stomachs are taken, the pyloric portion removedand the remainder of the mucous membrane carefully washed with water. The superficial portion of the membrane is then scraped off with a watch glass, and the substance thus obtained is ground up with a weighed quantity of salt. Enough water is added to this to make a saturated solution of salt. After standing 24-72 hours this was filtered and the Na Cl removed by dialysis. The dialysed liquid contained very little albumin and had a very powerful peptic action. It was further purified by being kept at 40°C. for some time to destroy the rennet ferment, and was then allowed to digest itself for one or two weeks, until all the albumin was converted into peptone. To this liquid chloride of calcium and acid sodium phosphate were added, and the liquid made ' This department is edited by Professor HENRY SEWALL, of Ann Arbor, Mich. *Zeitsch. f. physiol, Chemis. 9, 319.

The only reagent that affected it was absolute alcohol. When the pepsin solution was added to five or six times its volume of alcohol a slight white precipitate occurred. This, when burnt on platinum foil, gave the well-known odor of burning nitrogenous matter. The author concludes, that while pepsin is a nitrogenous body, it is not albuminous. CONTRIBUTION TO THE KNOWLEDGE OF BILE CAPILLARIES !.— Miura has discovered a modification of the gold method by which the bile capillaries can be stained, giving a simpler means for their study than the method of artificial injection usually em- ployed. Pieces of liver kept in Miiller’s liquid’ for two to five days are washed in water for several hours, and then transferred to a fifteen per cent solution of glucose for 2-3 hours. They are then placed in a 0.1 to 0.2 per cent solution of the double chlo- ride of gold and sodium for two or three days, and again placed in the glucose solution and allowed to reduce for two or three ys. Sections are cut by means of a freezing microtome. Miura has endeavored to settle two questions by this method, 1. Do the Kupffer vacuoles really exist in the liver cells as the beginning of the bile capillaries? His method gives no indica-, tion at all of these vacuoles, and he infers that, as usually found, they are artificial products caused by the pressure used in injec- tion. 2. Have the bile capillaries walls? When their sections were traced out he quite frequently found places in which the broken ends of the capillaries projected beyond the cells, or where they formed a bridge passing between two cells at a point where they had been separated by the tracing needle. He concludes from these appearances that the capillaries have walls of their own. ~ Tae Microscopic APPEARANCE OF STRIPED MuscLeE DURING Contraction *— The author investigated the muscle when thrown into maximal tetanus, and when the tetanus was not maxima The muscle was stimulated by induction shocks and killed dur- ing contraction by osmic acid or alcohol. The muscle of maximal tetanus when thus treated showed cer- tain bands (contraction bands) running across the fibers, repre- senting, doubtless, Krause’s membrane of the resting muscle. Between these contraction bands the fiber was swollen out, giving a convex border. Examined by polarized light, the whole sub- stance of the fiber is found to be doubly refracting. The contrac- tion band representing Krause’s membrane undergoes no change ce during contraction; it appears, in the author’s opinion, to play the _ Passive part of giving a fixed support from the shortening. The portions in between the contraction bands, also doubly refracting, --1Virchow’s Archiv., 99-512. Dr. Miura. *Du Bois Reymond ea 1885. S. 150.

When the tetanus was not maximal some of the singly refracting substance was still found in the contracted fiber. The results given go to support Englemann’s theory of muscle contraction, according to which the shortening of the contracted fiber is owing to the absorption by imbibition of the singly re- fracting substance of certain ultimate elements in the doubly re- fracting substance, thus becoming spherical during the act and decreasing in diameter. PSYCHOLOGY. Do MONKEYS INVARIABLY LEARN by EXPERIENCE ?—Some time ago I read a statement to the effect that monkeys were unable to learn by experience, a particular in which they were said to differ from cats. The experiment suggested was to show the animal its reflection in a mirror, and after a time to repeat the process and : observe whether it would be deceived a second time. I have never had the opportunity to try the experiment on monkeys, though I am told, on tolerably good authority, that a monkey can never Satisfy itself that there is not another monkey behind the glass. But my acquaintance with cats is somewhat larger, and I find that, after once thoroughly investigating the subject, a cat which has reached an age of discretion takes no further interest in its cwn reflection. The question in my mind is: if a monkey can- not learn by experience, how can it learn? for it seems to me that almost every means of learning can be reduced to some form of experience, or to something that is practically the same thing —W.

He likes to leap from a stump into my arms as I am on horseback, and go off with me at a full gallop. One day a lot of pigs got out of their enclosure through a little hole at the apex of an acute angle, or corner, of the fence. This angle widened into the garden where the pigs were not tolerated. As soon as “ Trip” saw them he went after them to get them out. They fled before him into this angle and began, slowly, of course, to make their way through. As soon as he saw them all within the angle, he stopped before its widest opening—the base—and intently watching, waited until the last one had crawled back — into its proper enclosure. He seemed to understand that if he made a dash at them they would turn around and rush back into gto General Notes. [September, the garden. As soon as they were all in he looked up with a proud and pleased expression, as much as to say: “Isn’t that a clever piece of strategy?” We all thought it was. But in num- berless incidents of a similar nature “Trip” has proved himself to be a dog of excellent sense and judgment—and often of “ rare we ability.” — Charles Aldrich, Webster City, Iowa, Fuly I1, 1885. ; Do THE LOWER ANIMALS SUFFER PAIN?—As bearing on this question so often asked, we may quote the following statements from Romanes’ “ Jelly-Fish, Star-Fish and Sea-Urchins ”: Before any rational scruples can arise with regard to the vivisection of a living organism, some reasonable ground must be shown for sup- posing that the organism, besides being living, is also capable of suffering. But no such reasonable ground can be shown in the case of these low animals. We only know of such capability in any case through the analogy based upon our own experience, and, if we trust to this analogy, we must conclude that the ca- pability in question vanishes long before we come to animals so ow in the scale as the jelly-fish or star-fish. For within the limits of our own organism we have direct evidence that the nervous mechanisms, much more highly elaborated than any of those which we are about to consider, are incapable of suffering. us, for instance, when the nervous continuity of the spinal cord is interrupted, so that a stimulus applied to the lower ex- tremities is unable to pass upwards to the brain, the feet will be actively drawn away from a source of irritation without the man being conscious of any pain; the lower nervous centers in the spinal cord respond to the stimulation, but they do so without Jeeling the stimulus. In order to feel there must be conscious- ness, and, so far as our evidence goes, it appears that conscious- ness only arises when a nerve-center attains to some such e- gree of complexity and elaboration as is to be met with in the brain. Whether or not there isa dawning consciousness in any nerve-centers considerably lower in the scale of nervous evolution, is a question which we cannot answer; but we may be quite certain that, if such is the case, the consciousness which 1s present must be of a commensurately dim and unsuffering kind. Consequently, even on this positive aspect of the question, we may be quite sure that by the time we come to the jelly-fish— where the object of the experiments in the first instance was to obtain evidence of the very existence of nerve-tissue—all ques- _ tions of pain must have vanished. Whatever opinions, therefore, __ We may severally entertain on the vexed question of vivisection as a whole, and with whatever feelings we may regard the “ blind ` fury ” who, in the person of the modern physiologist, “ comes _ with the abhorred shears and slits the thin-spun life,” we should be all agreed that in the case of these animals the life is so very thin- pun that any suggesti stion of abhorrence is on the face of it absurd. ~ A e ae 1885.] Psychology. QII PsycHiCAL REsEARCH.—The Society of Psychical Research held its third general meeting April 24, in London, to hear the address of Professor Balfour Stewart, F. R. S. This society was founded by Professor Barrett, on the 5th of January, 1882, and formally constituted on the 20th of February of the same year with Professor Henry Sidgwick as president. At present the membership is 586, A kindred society has been recently started in America. Since its commencement the society has issued eight parts of proceedings, and in 1884 commenced the publica- tion of a journal. In the autumn of 1884 a report of the Com- mittee on Theosophical Phenomena was issued for private circu- lation only. A large number of slips has been printed comprising a selection of the evidence collected in the various departments of inquiry. The greatest liberality on the part of members has enabled the society to do a great deal of printing. Professor Stewart says: “To my mind the evidence already ad- duced is such as to render highly probable the occasional pres- ence amongst us of something which we may call thought- transference, or more generally telepathy; but it is surely our uty as a society to continue to accumulate evidence until the existence of such a power cannot be controverted. We have operations, “It is no doubt quite conceivable that after a quantity of evi- dence on some subject has been collected the result of its discus- sion should prove that there is nothing in it worth inquiring into, at least nothing new. But a definite settlement even of a nega- tive character is not without its value, and this can only be obtained as the result of an exhaustive discussion. On the other hand it is conceivable that the result of such a discussion may be the establishment of new facts eminently worthy of record, and € next generation of our society would greatly blame the pres- ent if we decline to bring together, examine, and register the co- temporaneous evidence, so as to fit it, if not for our own final _ discussion, at least for that of those who shall come after us.” Part vit contains the following papers :— On the telepathic explanation of some so-called spiritualistic phenomena, by Frederick W.

ANTHROPOLOGICAL PuBLIcATIoNS.—The Philosophic Grammar of American Languages as set forth by Wilhelm von Humboldt, with the translation of an unpublished memoir by him on the American verb, by Daniel G. Brinton, A.M., M.D., professor of ethnology and archeology at the American Academy of Sciences, Philadelphia. (Read before the American Philosophical Society, March 20, 1885. Philadelphia, McCalla & Stavely, pp. 50.) The original MS. of the memoirs is in the Royal Library at Berlin, whence Dr. Brinton obtained a copy. The fundamental ideas of the Philosophical Grammar are these: “The diversity of structure in languages is the necessary condition of the evolu- tion of the human mind.” Historic grammar traces the forms of a language ; comparative grammar extends the investigation over many dialects or languages; philosophic grammar analyzes the inmost nature of languages with reference to thought. It is con- trary to the results of study that the monosyllabic, the holo- phrastic and the inflectional languages. were developed one from another. : On some doubtful or intermediate Articulations ; an experi- ment in phonetics, by Horatio Hale, Esq. London, Harrison & . Sons., St. Martin’s place. 1845, pp. 243. (Reprinted from Journ. Anthrop. Inst., Feb., 1885.) This essay discusses the mixing of sounds of the same character, m, b w; d, ¿Z n,r, and seeks to account for it. Three theories are proposed; careless utterance ; slight anatomical modifications in the speaker; failure of the listener to catch intermediate sounds. Mr. Hale in his paper develops the latter view, There is no doubt, as we have shown in another place, that the philologist must take into considera- tion the ear and the eye of the receiver of language as well as the vocal organs or the pen of the author. Furthermore, it will be found that all unwritten languages are holophrastic by agglu- tination or by incorporation, and that monosyllabism and inflec-. writing.

Dr. Brinton closes his address with an earnest appeal for the endowment of research in this direction. Silex Tertiaires intentionellement Taillés, by G. de Mortillet, L’ Homme, Paris, Mai, 1885, pp. 289-299, June, 252-262. Two propositions are insisted on in this paper, to wit: The flints of Thenay were wrought by means of fire, and the being who wrought the flints of the Tortonian and the Aquitaine epoch was not man, but an intelligent animal. This animal, more intelli- gent than the most intelligent recent apes, could not have been man like us, for all the higher animals have been modified since the middle Tertiary. That creature was intermediate between man and ape, a precursor of man. M. Mortillet has always given us great pleasure by the energy of his convictions, but in this paper, as in others lately published, there is a spitefulness which mars their effect. It looks very much like dodging the issues when we follow a man like De Quatrefages to the very brink of a conclu- sion and then shrink back, saying, “ The geologists tell us man could not have lived in that time.” See also an account of new diggings at Thenay by D’Ault-Dumesnil.

The description of Mr. Holmes covers the finding, age, use, construction, material, color, form, finish, ornamentation. As an artist Mr. Holmes lays himself out on the form and ornamental patterns. Believing with Klemm that every art commences with a natural object, the author has worked out by means of the Davenport pottery the shapes of the vessels and the figures traced upon them.

The nat- uralist and the philologist in their classifications accept the same criterium of perfection, it is the principal of the /ocalization of Junctions. The idiom which best distinguishes grammatical cate- gories, not confounding, for example the noun with the verb, has preéminence. In the study of this subject of differentiation we ve to examine a language in every particular, great progress being made in one direction, and that ofttimes from outside influ- ences, while the greatest simplicity remains in other particulars. M. Charencey regards monosyllabism as the simplest linguistic form, while agglomeration and inflection are subsequent stages. It seems to be nearer to the truth that monosyllabism and inflec- tion are literary effects in Speech both referable to earlier forms, perhaps agglutinative. M. Charencey devotes 130 pages to the discussion of the method in which the Maya language provides for the parts of the verb as known in the French languages.

Allow it to stand and cool; decant the clear fluid, add fresh water, and if necessary picric acid; boil, cool and decant ; repeat this operation until all the carmine is dissolved. Place the decanted fluid in an evaporating dish, add about one grain thymol and stand in a warm place until the volume is reduced to 25 c.c.; - let the solution cool; filter; wash out the residue which should be on the filter with 25 c.c. water; dilute the filtrate solution with 50 c.c. water. By this means a solution ready for use, which will keep indefinitely and contains capo and picric acid in good proportions, can be prepared with certainty. It gives a stronger differential coloring than Ranvier’s picric carmine, but overstaining must be avoided most carefully ; for staining sections two to five minutes are sufficient. The fluid stains connective tissues (fibrous) deep red, striped muscle deep , dull red, smooth muscle, blood and horny tissues bright yellow, glands reddish-yellow ; with the kidney it gives differentiation of the different portions of the tubules; for the central nervous sys- tem it seems to be of little value. If rightly used it gives a sharp nuclear colorin If the aqueous solution is evaporated to dryness the residue may be redissolved in alcohol, giving an alcoholic carmine dye. This I have not yet tested sufficiently. Apparently the alcoholic solution will not keep but a few months. The alcoholic solubil- ity of the dye offers the advantage that sections stained in the watery solution can be washed in alcohol directly.

By this arrangement the paraffine dishes are always kept dry and at a uniform temperature all over. e four rectangular basins are used for warming the slides. In each of them is a movable rack made of two tin slips, each about a half inch wide and folded as shown in Fig. 3. Each of these basins also has a copper lid with a button handle in the middle. Near the center of the bath a tube one inch in diameter passes from the ae top down to and through the bottom. Fic. 3.—Supports for slidesin This tube is the passage way for the per crate “we glass tube that connects the burner under the bath with the gas jet above the center of the bath, and it should be soldered to the upper side as well as to the under side of the bottom of the bath. Near this tube are two others, each one inch in diameter, that project about one anda half inches above the upper surface of the bath, but are soldered with their < lower ends flush with the under side of the top of the bath. One rough them the water is put in or taken out 1885.] Microscopy. 919 which it is supported on the copper tube. A bit of cotton in the bottom of the test tube protects the mercury bulb of the regu- lator or thermometer from any jars against the hard test tube. The holes in the sides of the test tube allow the water of the bath to come in direct contact with the mercury bulbs and at the same time they are up high enough to keep the mercury from running into the bath should either of the mercury bulbs break while in the tube. The copper bath is supported ina square box-table, the top of the bath being flush with that of the table. This table essentially is a box on four legs, with a hole in the top slightly more than twenty-eight inches in diameter, and with a door at one end. The bath is supported on four props that rest on the lower shelf of the table, and around the inside of the table is a lining of common tin to protect against possible accident. By this means a steady flame is obtained and the loss of heat is reduced toa minimum. And by grouping the regulator, ther- moméetor and gas pipe near the center of the bath, hindrances are practically done away with. There is also connected with the gas jet a small home-made glass Bunsen burner that is attached to the glass gas tube a little above the bath. It is very con- venient for warming dip tubes, lifters, etc. In so large a bath as this two flames are required, but both are burned very low. The one burner is connected directly with the gas jet and the other by way of the regulator. After the bath has, so to speak, been once set it runs on uniformly and requires no attention. Itis regulated by putting a thermometer through the hole in one of the lids into the dry chamber and shutting off the regulator burner when the chamber is warm enough. The temperature, as indicated by the thermometer that dips into the water, is always a few degrees higher than that of the dry chambers. When the thermometer inthe water indicates a temperature of 60° C. the basins are warm enough to keep the hardest grade of paraffine melted. The whole stands at a convenient working height, about three feet eight inches, and is very satisfactory—HHenry F. Nachtrieb, Fellow Fohns Hopkins University, SUGGESTIONS AS TO THE PREPARATION AND USE oF SERIES OF SECTIONS IN ZootomicaL INstTRuCTION.—It is convenient to have in the laboratory prepared series of certain types, so that the student may supplement the information he has acquired from 920 General Notes. [September, exceedingly convenient stain for such purposes, as it penetrates an object of considerable size readily, and differentiates admirably. Thus a Limax may be left in the fluid twenty-four hours, after- ward washed in water and the excess of coloring matter removed by seventy per cent alcohol before it is transferred to stronger alcohol. Sections of tissues stain in the fluid in from two to three minutes to two to three hours, according to the method of hard- ening that has been adopted. The fluid is prepared as follows: Rub up seven grammes of cochineal with an equal quantity of burnt alum in a mortar, add 700 c.c. of water, and boil down to 400 c.c. Add a trace of carbolic acid, and filter. Bismarck brown in concentrated solution in water or seventy per cent alcohol also stains well i” toto; there is no danger of over-staining, as the excess of color is removed by alcohol. It is particularly to be recommended where cartilaginous parts are to be studied, or where the sections are to be photographed. [The use of plates in which the sensitized surface is impregnated with a weak solution of eosin (Jour. Roy. Mic. Soc., Dec., 1884, p. is said to obviate the necessity of using special stains for photo- graphic purposes. } Schallibaum’s collodion and clove-oil mixture (one volume of the former to three of the latter) is excellent for sticking the sec- tions to the slide. Although it is possible by this method to stain the sections on the slide in either watery or alcoholic media, much time is saved, and on the whole more satisfactory results obtained by staining the objects previously zz toto. The collodion medium stains slightly in aniline colors, if staining on the slide be resorted to. Sr The study of a slide containing a large number of sections may, in certain cases, be much facilitated by having a photograph of the slide enlarged two or three times by means of an ordinary view lens. Such an enlargement is frequently sufficient to indi- cate where an organ appears or disappears in a series, and thus to save time in the study of the individual sections.—Professor R.

Q21 by the use of two injecting fluids, òf different densities, one pass- ing through the capillaries, the other arrested at the capillaries, the whole vascular system may be injected from the aortic arch. The application of the principle is as follows: (1) The animal is immersed in tepid. water an the heart is uncovered. (2) The apex of the single ventricle, in the case of an amphibian, or of the left ventricle in the case of higher animals is then laid widely open and the blood allowed to flow freely from the auriculo-ventri- cular aperture (see # in the figure).

When the body is thoroughly warmed, this mass is slowly in- jected. As the second ligature is still loose, a quantity of blood gradually followed by the gelatine issues from the auriculo-ven- tricular opening. (5) When the gelatine begins to run pretty clear, the second ligature is fastened and the syringe containing gelatine is replaced by another containing a red plaster-of-paris injecting mass. The latter drives the gelatine contained in the arteries before it as far as the capillaries, thus completely filling the venous system. When the gelatine is thoroughly cooled the animal is ready for dissection. - This method can be applied with considerable ease to all the smaller animals, such as frogs, lizards and pigeons, in preparation r class-work or investigation. Its advantages are numerous. Among its disadvantages may be mentioned the fact that alcohol cannot well be used as a preservative, because it dehydrates the gelatine, causing it to shrink and break up the veins. This diffi- culty is entirely obviated, however, by the use of Wicker- Sheimer’s fluid, in which the injection remains perfect for an in- definite time —Henry F.

Mr. Cheshire said that he must, in the first place, congratulate Dr. Maddox on the time he had been able to keep his bees alive in a state of isolation. They were not at all easy to keep so under ordinary circumstances. He had tried himself some similar ex- periments, and thought he had succeeded in infecting Musca vom- ttorta ; but it might be well to remark that in one hive bee he had found eight or ten distinct kinds of bacilli, one of which had a distinct curvature. Amongst bee-keepers there used to be an idea that the bees had no diseases, although there was one affecting the larve, but directly a careful examination of the bees was made it s was found that they were subject to a great many. One kind had the curious effect of causing all the hairs to fall out, and on exam- ining bees which were so affected he found them all to contain large numbers of the short red bacillus. If any one intended to experiment in these matters it might be useful to know that if the bees were fed with food stained with aniline dyes very curious effects were produced upon the internal organs. Differentiation took place within the body, and when they came to dissect them afterwards they would find it a very ‘great help. — Among the new investigations started in the Department of Agriculture, not the least important is one relating to economic ornithology. This work has been begun as a branch of that of the Division of Entomology, of which Professor C. V. Riley t bas charge. Dr. C. Hart Merriam, a well-known ornithologist, and secretary of the American Ornithologists’ Union, has been appointed a special agent to take charge of this part of the divis- tonal work. Dr. Merriam will make his headquarters at Sing Sing, New York, until October 1st, and after that at Washington. _ The scope of the investigation will cover the entire field of the inter-relation of birds and agriculture, particularly from the ento- mological standpoint. The inquiry will relate primarily to the food-habits of birds, but will include also the collection of data ing on the migration and geographical distribution of North American species. In this last inquiry the department hopes to _ have the cooperation of the American Ornithologists’ Union, Dr. o erriam being in charge of the Committee on Migration for said nion. — An officer of the Italian navy (reports Mature) after a course of four months’ instruction at the Zoological Station at Naples, 924 Scientific News, [September, was attached to the corvette Vettor Pisani. After an absence of five months the first consignment arrived—the product of deep- sea work, of dredging and coast-fishery along the shores of Gibraltar, Brazil, and Montevideo; a second collection still more. extensive than the first was made during a voyage from Monte- video to Cape Horn, and among the islands of the Patagonian group. Other collections have been made on the Peruvian coast, the Gallapagos islands, and from Panama; also animals from small pools and rivers in Peru. Those from Peru comprise two complete series of embryonic forms—one of a ray, the other of a toad. The Vettor Pisani continued its course from Peru to the Philippine islands and China. The results have been so satisfac- tory that three other Italian naval officers were received at the station, one of them being afterwards stationed at the mouth of ‘the Red sea, while another is collecting in the Mediterranean. —Dr. W.

He illustrates the value of such evidence by reference to actual cases, and points out the differences between human and animal hair, and the distinguishing features of hair from those of the more com- mon filaments which may be mistaken for it, such as the finer fibers of jute, linen, silk and cotton.

The expedition was fitted out at the expense of the King of Prussia and the British East India Company, and added many important and interesting facts to our knowledge in the domains of geography, meteorology, geology, and ethnology. An account of the journey was published in English under the title of “ Results of a Scientific Mission to India and High Asia.” Prof. Robert von Schlagintweit also traveled in North America, and wrote several shorter works on his experiences there. — Mr. Mellard Reade’s presidential address to the Liverpool Geological Society has been reprinted in the form of a pamphlet entitled “ Denudation of the two Americas.” The essay may be regarded as a sequel to the address in which he discussed the effects of chemical denudation as a geological agent. He insists strongly on the importance of applying quantitative methods to K the study of geological phenomena. In.the present paper he calculates the amount of solid matter removed in river-water from the surface of some of the principal river-basins of America. Mr. Reade thinks that the matter which exists in chemical solu- tion in river-water has more importance as a factor in the recon- struction of the earth than is generally recognized by geologists. —English Mechanic. — Prof. C.

April 28.—Mr. Morris stated his conviction that the swim-blad- der in fishes was a degenerate organ, formerly of use, but now without an important function. The fact that in embryonic states 928 Proceedings of Scientific Societies, [September, it is connected with the cesophagus by a duct points to the idea that it formerly performed, to some extent, the function of a lung. The speaker believed that in previous ages fishes visited the land in search of food much more frequently than now, and that an air- breathing apparatus was developed by a pouching of the cesopha- gus. When the increased number of predatory land animals compelled fishes to confine themselves to water, this structure degenerated. A paper by Mr. W. S. Blatchley “On the genus Aphredoderus” was presented for publication. r. T. Meehan, in the Botanical Section, remarked on the pecu- liarities of Mammillaria haydeni, and other allied species, the ovaria of which remain buried between the closely appressed walls of the mammz from April or May until just before the next flowering season, when they stretch out to their full length in a single night. As in this species the fruit is two inches long, and bright red, the effect of its sudden appearance, which is certainly due to elastic projection and not to growth, is very striking. May 5.—Mr. Willcox stated that Florida sea-urchins were cov- ered in March with shells, some of which contained living mol- lusks. In January they were free from this covering. /udgur perversus is embedded in the sand when spawning, and attaches the smaller end of the egg-string, first protruded, to a stone below her. When the entire string is liberated the portion last pro- truded floats out with the tide. As only four or five capsules are to be found in the mollusks at one time, the process of laying the string probably occupies weeks, The speaker stated that he had found specimens only three and a half inches long in the act of spawning. ' Professor Heilprin exhibited a pebble from the yellow gravel near Glassboro’, containing Scolthus linearis, This, which he believed to be the first instance of the occurrence of the fossil in New Jersey, pointed, as did other Silurian and Devonian fossils collected in the same locality, to the origin of the deposits in the eastern continental border. ` Mr. A.

The migration of birds, dates of blooming of spring flowers, etc., are carefully noted. Professor Lewis exhibited specimens of fossil plants from the new tunnel at Phcenixville. Some minute phyllopods were also. _ described, The same beds were found in abundance in certain _ beds at Gwynedd. ; _ Professor Lewis also exhibited specimens of erythrite from - Pheenixville, and of cuprite from Frankfort. The former has never before been found in North America, and the latter is new 1885. | Proceedings of Scientific Societies. 929 Professor Heilprin called attention to the grouping, by Professor Eugene Smith, of the phosphate beds discovered by the latter, with the Jackson and Vicksburg deposits, as Oligocene. The palzontological character of the beds was given, and the conclu- sion drawn that there was a strong line of demarkation between m. “A review of the genera and species of Mullidæ,” by E. A. Hall and T. Z. McCaughan, was presented for publication. May 19.—Professor Lewis announced the discovery of genthite in the Lafayette soapstone quarry. ccurs in small, bright, emerald-green crusts, showing the stalactitic structure character- istic of the species. This discovery proves the presence of nickel in the Pennsylvania serpentines. Mr. Jos. Willcox stated that genthite had also been found at Webster, N. C. Dr. Leidy described a number of tape-worms of a new species from a trout. The specimens were mature, measured from three to eight inches in length, and contained eggs in the segments near the head. The name Bothriocephalus cestus was proposed for it. Mr. Potts stated that he had found a digestive cavity in the hydroid without tentacles previously described by him, and had seen it capture and swallow its food. he name Microhydra ryderi was given to it; genus and species both new. Miss Fielde stated that, as a high authority upon nerve tissue had suggested that its reproduction in the earth-worms she had experimented upon was simulated, and that such reproduction was impossible, she had carefully examined the specimens, and found the tissue to be real, and as sensitive as the primitive growth. All the life processes were now performed as completely by the worms which had been decapitated as by those which had not been injured. May 26.—Professor H. C. Lewis gave the result of his studies of the extreme southern edge of the ice-sheet in Pennsylvania. Certain short ridges of stratified drift, which often seemed to repre- sent a backward drainage of the melting edge of the glacier, were spoken of as marginal kames. The speaker then described kames, eskers or osars, as studied in various parts of the world, and dis- cussed the various theories of their origin. The kames are of gravel, fine within, often coarse without, and boulders and till often lie upon them. They contain no shells, and their courses coincide with the general drainage of the country. These kames seemed to be due to sub-glacial streams draining the edge of the ice-sheet. When the terminal moraine rested against an upward Slope this drainage was backward or into the ice. ' June 2—Mr. W. N. Lockington gave an account of the pro- gress of European colonization in Africa, and the opposition to it likely to be presented by the spread of Islamism.

MYTHIC DRY-PAINTINGS OF THE NAVAJOS. BY DR. W. MATTHEWS. DESIRE, in this article, to call the attention of ethnographers to some pictures which are among the most transitory in the history of human art. They are the work of the Navajo Indians, a people who make no graven images of their gods, who do not decorate skins or robes, who place no symbdls on their rude and rarely-made pottery, and may be said to have no rock inscriptions, A few slightly scratched sketches on the cliffs of Arizona and New Mexico may, perhaps, be attributed to them; but the vast Majority of carvings on stone in their country, and all of the most permanent character, are the work of the sedentary races. Seeing no evidence of a symbolic art among them, one might readily be led to suppose that they possessed none. Such was my opinion for two years after I had come to reside near them. Such is the opinion of many white men, who have lived for periods of from ten to twenty years among them. During my residence of nearly four years in New Mexico I had heard of these drawings through the less conservative Indians and through a Mexican who had been many years captive among them. But it was not until last November, when I made a spe- cial journey to the Navajo country under the auspices of the Bureau of Ethnology, that I obtained unrestricted access to the medicine-lodge, saw the hieratic figures drawn, and was given Permission to sketch them, much to the horror of the large Majority of the assembled multitude. The medicine-lodge, on the floor of which these pictures are made, is a simple conical structure of logs in the shape of an VOL, XIX.—No, X. 6r 932 Mythic Dry-Paintings of the Navajos. [October, Indian skin tent. It is about twenty-five feet in diameter at the base, internally, and about eight feet high under the apex. The only apertures are a smgke-hole above and a door, communicating through a short passage-way, in the east. The fire is built in the center of the floor except when the pictures are being made, then it is removed further to the east to make room for them. It is so dark in the lodge that on a brief winter day the artists must begin their work before sunrise if they would finish before night-fall and this it is essential they should do. When the call is sounded in the morning, several young men go forth and bring in a quantity of dry sand in blankets; this is thrown on the floor and spread out over a surface twelve feet or more in diameter, to the depth of about three inches; it is leveled and made smooth by means of the broad oaken battens used in weaving. The drawings are begun as much towards the center as the design will permit, due regard being paid to the precedence of the points of the compass; the figure in the east being begun first, that in the south, second, that in the west, third, that in the north, fourth. The figures in the periphery come after these. The reason for working from within outwards is a practical one; it is that the operators may not have to step over and thus risk the safety of their finished work. While the work is in progress the chief shaman does little more than direct and criticise ; a dozen or more young men per- form the manual labor, each working on a different part. These assistants have had a certain ceremony of initiation performed over them before they are admitted to the lodge or allowed to help when these pictures are made; but they need not be skilled medicine-men or even aspirants to the craft of the shaman. They t nothing for their pains but their food, which, however, 15 abundant. Three times a day the person, for whose benefit the dance is performed, sends in enough mush, corn-cake, soup and roasted mutton to satisfy to the utmost the appetites of all in the lodge. The shaman, or hathali (chanter or singer), as the Nava- : S __ jos call him, gets a rich present for his services. _ The pictures are drawn according to an exact system, except _ in certain well-defined cases, where the limner is allowed to in- _ dulge his fancy. -This is the case with the embroidered pouches e gods carry at the waist (see Plate xxx). Within reasonable 1885.] Mythic Dry-Paintings of the Navajos. 933 limits the artist may give his god as handsome a pouch as he wishes. On the other hand, some parts are measured by palms and spans, and not a line of the sacred design can be varied in them; straight and parallel lines are drawn on a tightened cord. The pigments are five in number: they are black made of char- coal; white, of white sandstone; yellow, of yellow sandstone; red, of red sandstone, and “ blue,” of the black and white mixed in proper proportions; all ground into fine powder between two stones. The so-called blue is, of course, gray, but it is the only inexpensive representative of the cerulean tint they can obtain, and, combined with the other colors on the sandy floor, it looks like a real blue. These colored powders are kept on improvised trays of pine bark ; to apply them, the artist grasps a little in his hand and allows it to flow out between the thumb and the op- posed fingers. When he makes a mistake he does not brush away the color, he obliterates it by pouring sand on it and then draws the corrected design on the new surface. The naked forms of the mythical figures are first drawn, and then the clothing is put on. Even in the representations of the Bitses-ninez, or long bodies, which are nine feet in length, the naked body of each is first made in its appropriate color—white for the east, blue for the south, yellow for the west, black for the north—and then the four shirts are painted on as shown in the picture (Plate xxx) from thigh to axilla. It is the task of the shaman, when the work of painting is completed, to put the corn-pollen, emblem of fecundity, on the lips and breast of each divine form, and to set up the bounding plume-sticks around the picture. Then the one who gives the feast enters and is placed sitting on the form that belongs to the east—the white form—and looking eastward. Here the colored dust from various parts of the divine figures is taken and applied to corresponding parts of the patient, and many other ceremonies are performed, which it is not my purpose to relate here. When the patient has departed many of the spectators pick up the corn- Pollen, now rendered doubly sacred, and put it in their medicine- bags. Some take dust from the figures on their moistened palms and apply it to their own bodies. If the devotee has disease in i his legs, he takes powder from the legs of the figures; if in his head, he takes powder from the head, and so on. By the time they are all done the picture is pretty badly 934 Mythic Dry-Paintings of the Navajos. [October, marred. Then it becomes the duty of the shaman to completely’ obliterate it; this he does with a slender wand, while he sings the song appropriate to this part of the ceremony. He begins with the figure belonging to the east, the white figure, and proceeds in the same order as was observed in making the picture, 2. e., in accordance with the apparent daily course of the sun, The fig- ures at the margin are erased last, and when this is being done the bounding plume-sticks are knocked down. When no sem- blance of the picture is left the assistants gather the sand in their blankets, carry it to a little distance from the lodge and throw it away. Thusin half an hour after the completion of a large pic- ture, ten or twelve feet in diameter, which has taken a dozen men, or more, eight or ten hours to construct, not a trace of it is left. I have learned of seventeen great ceremonies of the Navajos, in which pictures of this character are drawn, and I have heard that there are, on an average, about four pictures to each dance. This would give us about sixty-eight such designs known to the medicine men of the tribe. But I learn that there are different schools or guilds among the medicine men who draw the pictures differently in some of the details, and that besides these seventeen great ceremonies there are many minor rites, with their appro- priate pictures; so the number of designs in the possession of the tribe is probably much greater than that which I give. The medicine-men aver that these pictures are transmitted from teacher to pupil, in each guild and for each ceremony, unaltered from year to year and from generation to generation. That such is strictly the case I cannot believe. No permanent design is pre- served for reference, and there is no final authority in the tribe, The majority of the ceremonies can be performed only during the months when the snakes are dormant. The pictures are there- fore carried over, from winter to winter, in the fallible memories of men. But I think it probable that innovations are uninten- tional, and that any changes which may occur are wrought slowly. __. Out of this possible number of sixty-eight or more pictures I _ have seen seven, colored copies of which will, I hope, appear in some future report of the Bureau of Ethnology. The majority are too intricate to be reproduced in a satisfactory manner from a -wood-cut on a page of this size, I therefore present illustrations f as two, and these of the simplest, PLATE XXXIII. piy Wn n Hi { =| M ann Il = eu q ) FN M VINI il a ‘i | | | A | Navajo Dry-paintings. The Long Bodies. | | | Hl WAH Hi wi Se 1885.] Mythic Dry-Paintings of the Navajos. 935 The first four pictures in my collection are those of the Dsi/yidje hathal, or chant among the mountains. This ceremony is also called ilnasjingo hathal, or chant in the dark circle of branches, from the great corral of piñon boughs in which it is performed. As the public ceremonies of the last night are varied and interesting, it is best known to the whites of all Navajo dances, and by our people is commonly called the hoshkawn dance, from the partic- ular performance of the night, which seems most to strike the Caucasian fancy. The whole ceremony is propitiatory to the Yéis, or gods of the mountains ; but when the Navajo prophet, who learned these mys- teries, was brought around by a friendly god from place to place to be taught them, he was, on one occasion, brought into the house of the serpents. Now the worship of the snakes and water animals constitutes a separate dance, that of the hojoni hathal, or chant of terrestrial beauty, with its own pictures and ceremonies ; but to indicate that the prophet visited the snakes in his wander- ings and saw a portion of their mysteries, this picture, represent- ing the home of the serpents, is drawn (Plate xxx11). In the center of the picture is a circular concavity about six inches in diameter, intended to represent water. In all the other pictures where water was represented, a small bowl, I observed, was sunk in the ground and filled with water, which was after- wards sprinkled with powdered charcoal to give the appearance of a flat, dry surface. Closely surrounding the central depression are four parallelograms, each about four inches wide and ten inches long in the original pictures; the half nearer the center is red, the other half is blue; they are bordered with narrow lines of white. They appear in this and in some other pictures as something on which the gods seem to stand, and symbolize the sha'bitlol, or raft of sunbeams, the favorite vessels on which the divine ones navigate the upper deep. Red is the color proper to sunlight in their symbolism; but red and blue together represent sunbeams in the morning and evening skies when they show an alternation of red and biue. The sunbeam shafts, the halo and the ___ fainbow are painted in the same colors, but they differ in form— the halo is a circle; the rainbow is curved and usually anthropo- morphic, in Plate xxxii, however, it is plumed. External to these sunbeam rafts, and represented as standing on them, are the figures of eight serpents—two in the east, white; two in the 936 Mythic Dry-Paintings of the Navazos. [October, south, blue; two in the west, yellow, and two in the north, black. They cross one another in pairs, forming four figures like the let- ter X. In each X the snake which appears to be beneath is made first, complete in every respect, and then the other snake is drawn over it in conformity with their realistic laws of art before referred to. The neck in all cases is blue, crossed with four bands of red, which, in the snake-like forms run diagonally, but in the man-like forms to be seen in other pictures, run transversely. The V-shaped marks on the backs of the snakes represent mot- tlings; the four marks at the end of each tail are for rattles. Ex- ternal to these eight snakes are four more of much greater length but colored to correspond with those already described. They seem to follow one another around the picture in the direction of the sun’s apparent course, and form a frame or boundary. In the north-east is seen one of the Yeis, who accompanied the Navajo prophet to the home of the snakes. In the extreme west is a black circular figure representing the mountain of Dsilya-ithin, whence they descended to visit the snakes. In the original picture the mountain was in relief—which I have not attempted to con- vey in my copy—a little mound of sand about ten or twelve inches high. From the summit of the mountain to the middle of the central waters is drawn a wide line in corn meal with four footprints depicted at intervals; this represents the track of the bear. Immediately south of the track is the figure of an animal drawn in the gray pigment, this is the grizzly himself, symboliz- ing the prophet. _ During the journeys of the Navajo prophet before referred to, he came one night in the Carrizo mountains to the home of the _ four bear-gods (so runs the legend). They took from one corner of their cave a great sheet of cloud, unrolled it and exhibited to his view a picture. They told him that this picture must be drawn by the Navajos in their ceremonies; but as men had not the power of handling the clouds they should draw it on sand. This picture, a very elaborate one, not illustrated in this article, represents the Yeis of the cultivated plants. It shows the central | waters and the sunbeam rafts as in the first picture. It has four : opomorphic figures extending from the center to different points of the compass, and highly conventionalized representa- — ons of the four principal domestic plants of the Indians—corm, ar Ta and tobacco. The whole is surrounded on three 1885. ] Mythic Dry-Paintings of the Navajos. 937 sides by the anthropomorphic rainbow. The body of the eastern god is white; that of the southern, blue; that of the western, yel- low ; that of the northern, black. l Here is an appropriate occasion to speak of Navajo symbol- ism in color. In all cases, as far as I could learn, the south is represented by blue, the west by yellow, the upper world by blue, the lower world by black and white in spots. Usually the east is represented by white and the north by black; but some- times these colors are interchanged and the north becomes white while the east is black. The reasons for this change are too lengthy to be discussed here. It is related in the myth which accounts for these mysteries, that this Navajo prophet, Dzz/’-yi-neyant, or Reared among the Moun- tains, was once led by the gods to a dwelling called the Lodge of Dew; it was built of dew-drops, and the door was made of many plants of different kinds. They entered and found four goddesses called Bitses-ninez or long bodies. The holy ones rose as the strangers entered, and they were very tall. The plumes on their heads almost touched the sky. They said to the prophet: “ In the rites that you will teach your people when you return to them, you will invoke us by drawing our pictures. We stand here, one in the east, one in the south, one in the west and one in the north; but when you draw the picture you must place us all in the east.” The third picture in the series (Plate xxxtt1) is supposed to be made in accordance with these instructions. To indicate their great height the figures are twice the length of any in the other pictures, except the rainbow figures, and each is clothed in four garments, one above another; for no one garment, they say, can be made long enough to cover such giant forms. The form im- mediately north of the center is done first, in white, and repre- sents the east; that next to it, on the south, comes second in order, is painted in blue and represents the south. The form next below the latter is in yellow and depicts the goddess who stood in the west of the house of dew-drops. The figure in the extreme north is drawn last of all, in black, and belongs to the north. As before stated, these bodies. are first made naked and afterwards clothed. The exposed chests, arms and thighs display the colors of which the entire bodies were originally composed. Some small animal called the g/oi is sacred to these goddesses. Two of 938 Mythic Dry-Paintings of the Navajos. [ October, these creatures are shown in the east, guarding the entrance to the lodge. The appendages at the sides of the heads of the god- desses represent the g/di-bichd, or head-dresses of g/oi skins of different colors, which these mythic personages are said to wear. Each one bears, attached to the right hand, a rattle, a charm and a branch of choke-cherry in blossom (highly conventionalized). Some other adjuncts of the picture—the red robes embroidered with sunbeams, the forearms and legs clothed with clouds and lightning, the pendants from wrists and elbows, the blue and red armlets, bracelets and garters—are properties of nearly all the anthropomorphic gods shown in these pictures. The rainbow which encloses the group on three sides is not the anthropomor- phic rainbow, it has no head, neck, arms or lower extremities. Five white eagle-plumes adorn its south-eastern end; five tail- plumes of some blue bird decorate the bend in the south-west; the tail of the red-shafted flicker is near the bend in the north- west, and the tail of the magpie terminates the north-eastern extremity. Throughout the myth not only is the house of dew spoken of as adorned with hangings and festoons of rainbows, but nearly all the holy dwellings are thus embellished. The fourth picture represents the Kaéso-yisthan, or great plumed arrows. These arrows are the especial great mystery, the potent healing charm of the dance. On the last night, many public alilis (shows, dances) may be given—shows of all sorts of socie- ties and bands, shows adopted from alien tribes. From dark to dawn these continue around the great central fire and within the dark fence of evergreen branches. All of these may be changed, omitted, or have others substituted for them, except the dance of _ the great plumed arrow, this cannot be left out. The three paintings remaining to be described are those of the kledji-hathal (chant of the night), or dance of the Yeibichai (grand-uncle of the gods). They represent some of the visions of another Navajo prophet named Sho. The myth recounting __ his adventures is interesting, but too long to be related here. In childhood and youth he showed signs of unusual wisdom. He often told his immediate relations that he held converse with the gods; but they doubted him until, as he grew older, he exhibited such unquestionable evidence of second-sight that the most skep- tical were convinced. On one of his rambles he saw what he to be a small herd of big-horn or Rocky-mountain 1885.] Mythic Dry-Paintings of the Navajos. 939 sheep, and went in pursuit. Four times he waylaid them and tried to shoot them, but each time when he drew his arrow to the head it would not leave the string. Then he knew the sheep to be divinities in disguise. He approached them; they threw off their sheep-skin coverings and revealed themselves as the géaskidt or gods of plenty. They bore Sho to their home, admitted him to their sacred rites, taught him all their mysteries, and sent him back to his people that he might teach the mysteries to man. All his adventures and visions are embodied in the myths and rites of the £/edjt-hathal. When his mission was done he was taken back by the gods to dwell among them forever. The form of the gdaskidi appears several times in the pictures. It is represented as having sheep’s horns on the head, wearing a crown of black clouds garnished with lightning and fringed with sunbeams, bearing on the back a great sack made of the black thunder-cloud (said to be filled with all sorts of edible seeds and fruits), and leaning on a staff to indicate that the sack of plenty isa heavy burthen. Various other important characters of the Navajo mythology appear in these pictures. One of the Yezdichai paintings delineates a very singular vision or revelation of the prophet So. It is called the ¢szznadle, or whirling sticks. On one occasion Sho was led by the gods to the shores of a dark lake, on the borders of whick grew four stalks of sacred corn, each of a different color. In the center of the lake lay two logs, crossing one another at right angles; near the two extremities of each sat a pair of Yeis, male and female, making eight in all. On the shore of the lake stood four more Yers, three of whom had staves, by means of which they kept the logs whirling around with a constant motion, while the Yes sitting on the logs sang songs which are still preserved in the multitudinous chants of this rite under the name of fstznadle-bigin, or songs of the whirling sticks. All the circumstances of this strange scene are duly symbolized in the painting. The two other pictures represent scenes in the dance of the Yeibichai, as Sho witnessed it among the gods, and with some- modifications they would make fair representations of the dance as it is enacted by the Navajos to-day. The pictures are beauti- ful, and appear of high interest when their symbolism is explained; * but I have not space to describe them, and, as before stated, they are too intricate to be suitably illustrated here. 940 The Relations of Mind and Matter. [October, THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. (Continued from p. 857, September number.) V. THe CONDITIONS OF CONSCIOUSNESS. HE greatest mystery of the universe is the mystery of con- sciousness. That we can ever understand its innate nature is not to be expected. The mind may measure everything out- side itself, but it cannot measure itself. The eye sees everything except the eye. There must always remain one thing unknown; that to and by which everything else is known. But though the nature of consciousness may be beyond our ken, its relations to matter and the mind are not necessarily so. Some of these rela- tions are apparent. Others are within the reach of conjecture. We are therefore free to consider the mystery of consciousness from this point of view. The character of consciousness has undoubtedly been greatly misapprehended, even by some very acute thinkers. It is cus- tomary to talk and write as if consciousness and mind were iden- tical, or as if the words thought and consciousness were synon- ymous. It is, indeed, on this ground that the brain-mind theorists have based their deductions. They find that the existence of consciousness and the loss of brain force are closely related. Thought bears heavily upon the nerve cells. They sink beneath its pressure, lose their organization and yield energy, of which there is no evident physical display. This energy, as is claimed, is the element of consciousness, and its successive manifestations constitute the mind. But this amounts to a distinct claim that the consideration of the origin of consciousness involves that of the whole mental constitution, and that thought and the conscious perception of thought are one and the same thing; a hypothesis which may safely be disputed. For the mind impresses us with a sense of unity and continuity which certainly do not belong to consciousness. Its thoughts continue to exist, whether or not we _ are conscious of their existence. A thought may arise to our mental perception to-morrow, another next year, a third only , after a decade of years. But they are evidently the same thoughts that we formerly knew. Their loss to sight has had no effect on their persistent existence. The action of consciousness or men- een is, in fact, singularly like that of the eye. We per- 1885.] The Relations of Mind and Matter. 941 ceive to-day a landscape which we saw twenty years ago. There it has lain unchanged, all its salient points familiar to our sight, though we may have since wandered over half the world. So the eye of the mind wanders over a world of thoughts and sud- denly perceives a mental landscape of which it lost sight twenty years before. There it lies, far more unchanged even than the physical landscape, for that has suffered innumerable changes, while the mental picture has seemingly remained utterly free from influences of change, Whether consciousness is an energy in itself, or a forceless side product of energy is a question that has been considerably de- bated. Professor Huxley takes the latter view, and declares that consciousness is not an agent in determining action, but is a col- lateral result of the action. Professor Cope considers that “ con- sciousness is not a necessary condition of energy,” though “ en- ergy is a necessary condition of consciousness,”’ and differs from Huxley in believing that consciousness exerts a directing influ- ence over mental action. In respect to these views it is impor- tant to observe that the mental operations which are generally attended by consciousness are capable, in some cases, of proceed- ing unconsciously. There are on record many striking instances of the active operation of the mind during unconsciousness, or while consciousness was elsewhere directed, important results of reasoning being sometimes produced. There are few thinkers to whom minor instances of this kind have not occurred. Such cases would seem to prove that consciousness is not a necessary element of thought, and therefore not a determining agent in thought. On the other hand it must be remembered that such mental processes never begin in unconsciousness, In every ‘ recorded case they have been trains of thought with which con- Sciousness was at first actively concerned, and whose movement has proceeded during a temporary lapse of consciousness, their final results again rising into the realm of conscious thought. Instances of this kind, however, are comparatively few, and seem only to occur where the preliminary train of thought has been in- tense, and the conscious attention close and active. This intense activity seems to set in movement energies of the mind, which, like a train of wheels set in motion by the hand, run on for some time after the acting agent has been withdrawn, and only slowly - TOn Catagenesis, AMERICAN NATURALIST, Oct., 1884. 942 The Relations of Mind and Matter. [October, sink into a state of rest. There is not a shred of evidence that such mental movements ever take place without the preliminary attendance of consciousness. They may possibly be produced in a minor degree by less energetic consciousness, but in every case they soon sink to rest, as friction brings wheels to rest when their moving force is withdrawn. And the mind, no more than the wheels, seems capable of starting into activity without the aid of some directing agent. There is nowhere in physical science evidence of the possible existence of a side product of energy which is not itself an energy. Motor energy varies in its mode of action, but every variant has a force influence of its own. A current of electricity, for instance, when resisted in its passage, here yields heat, there light and there magnetism, but the electricity loses in vigor with every such side expression, and the heat, light or magnetism at once exert force. The flash of light which gleams out when the electric current passes through the air, signifies a conversion of part of the current into the vibratory motion of light. May not the flash of consciousness which gleams out on the passage of motor energy from brain to mind signify a like partial side conversion of this energy? And if so it may possibly produce effects of its own, calling the mental organism into activity, or exerting some directing force upon the mental activities, as Pro- fessor Cope holds. Under the hypothesis here advanced, that the brain is not the organ of the mind, but that there exists a distinct mental organism separate from though intimately related to the brain, the condi- tions of this organism must be closely analogous to those of all organized masses. We may, therefore, compare the mental or- ganism with the crystal of some mineral. The latter is persistent, its internal relations of motion and attraction being in exact har- mony. If undisturbed its internal conditions would remain un- changed indefinitely. But the motor energies of the external world penetrate the crystal and may disturb its organizing motions, producing changes in the relations of its particles. So a seed under conditions of isolation is a persistent organism, held : __ intact by the harmony of its internal energies. Exposed to the . inflow of external energy its organization changes. The insti- : gating touch of such inflowing energy may set up long continu- ing changes in the motor relations of the particles of the seed, 1885.] The Relations of Mind and Matter. 943 and cause important modifications in its constitution. These cases seem closely analogous to what we know of the constitu- tion of the mental organism, though the susceptibility of the lat- ter to external influences is far greater. Yet it has a fixed organi- zation through the harmony of its internal energies. It is ex- posed to the inflow of external energies through the medium of the brain. And its internal conditions change under the influence of these inflowing energies. But at every resting stage of its development it gains a stable condition of internal energies, which remains persistent during the temporary absence of consciousness, And consciousness appears to be a peculiar expression of the motor energy which flows from the brain into the mind, The nerve current appears to produce chemical disintegration in some highly unstable element of the brain cells, as in the muscle cells, The energy set free by this disintegration seems merely to inten- sify without changing the character of the influence producing it, It flows into the mental organism, and in so doing takes on the special condition of consciousness, or manifests consciousness as one of the effects of its intact with the mind. Its final effect, however, is to impress the mind with a new motor state, which directly or indirectly repeats the conditions of the instigating ex- ternal energy. If such be in any sense a correct conception of the character and relations of the mental organism, certain other necessary consequences follow. Not only does the mind receive energy from the brain, but its innate energies affect the brain, and set up disintegration in its cells like that produced by the nerve current. And the energy produced by this disintegration flows out as a nerve current over the motor nerves to the muscles, which it rouses into activity.! Such is the two-fold relation of the mind to external nature. But it has interrelations of its own. Thought energies flow from part to part of the mental organism, and ideas are evolved from their interconnection, much of the mental evo- 1 The indications are that external energy does not flow directly into the mind, nor does mental energy flow outwards, In both cases an intermediate energy is used, that set free by chemical change in the tissues of the brain, The inflowing nerve current induces this change, and the mind is affected by the energy thus set free. In like manner the mind does not emit energy, or only to the slight extent necessary for inductive action. It exerts force on the brain cells, and induces a special emission of nerve energy. It constantly receives, but it never yields its stores of motor en- ergy. It resembles a land-locked lake, into which hundreds of streams flow, but to - which there is no outlet, 944 The Relations of Mind and Matter. [October, lution taking place through the interchange and combination of these internal energies. Yet the conditions of this activity seem ` identical with the other activities described. The mental organ- ism has no more power of arbitrarily changing the relations of its own energies than has a crystal. All such changes arise through its connection with an external reservoir of energy, the brain. The seeming movements of thought through the mind are really actions of the energies of thought on the brain, the release of brain energy, and the inflow of this energy into another region of the mental organism. This mediation of the brain is signified by the physiological change that takes place, and also by the appearance of consciousness, a condition which seems only existent during motor interconnection of the brain and the mental organism. We may reiterate here the fact that no organized mass—crys- tal, seed, solar system or mind—is capable of setting up new actions within itself, or arbitrarily instigating changes in its con- ditions of motor equilibrium. Such an action would be quite as impossible, if we may offer a homely illustration, as the old problem of a man lifting himself ina tub. Organizing motions cannot possibly change of themselves. Perturbations may arise through their interaction, as between the bodies of the solar sys- tem, but not permanent changes. And by the very conditions of their existence they resist change. All permanent change must come from the inflow and action of external energy, and it will be resisted to a degree in accordance with the rigidity of the organism. In the crystal, for instance, the resistance is vigorous. In the mind it is much less so, and varies extremely in minds of different degrees of development. If all mental change was pro- duced by external impulse, then the brain might be its organ. But the existence of internal mental change renders this impossi- ble. Such change can only take place under the instigation of external energy, and the brain is the source of this energy. The thoughts which seem to flow from region to region of the mind, evidently do so through the intermedium of the brain, since all activity of thought is attended with chemical change in the brain _ cells, And the energy thus yielded is the active agent in the new _ idea formed. It would seem as if every rapport between brain and mind instigated oxidation in the brain cells, the energy yie oat. none, to the Panas, or to another region of the mind, 1885.] The Relations of Mind and Matter. 945 over the brain fibers, on the same principle as external energy penetrates to the mind over these fibers, In this view the mental organism has a space extension, equivalent to that of the cere- brum, and each region bears a relation like that of external nature to every other region. The vividness of consciousness seems closely related to the degree of disturbance which it produces in the conditions of the mental organism. Energetic sensory impressions seldom fail to arouse consciousness, even if the mind is otherwise active. Less energetic ones may fail under such conditions. It is not unusual to discover that impressions have been unconsciously received during a period of mental abstraction. Possibly the movement of thought processes during unconsciousness is due to the small volume of energy engaged. An important fact, in this connec- tion, is that unusual impressions arouse the consciousness more quickly and vividly than usual ones, The mind seems to become dulled to a sensation when it has become habituated to it. With every repetition of any special current of energy it seems to create less disturbance in the mind. This may be partly due, if the sensation is one to which immediate motor response is requi- site, to the drafting off of part of the energy to the muscles, But even where this is not the case, and the impression is made wholly on the mind, its intensity diminishes with repetition, while all unusual sensations at once arouse active consciouness, Usual ones can only regain their original intensity of influence by an increase in their vigor. It would appear as if the vividness of consciousness depended upon the degree of change produced by a sensation in the mental conditions, and that each habitual sen- Sation found accordant mental conditions, and therefore feebly affected the mind, while every new one produced a degree of change in accordance with its degree of rarity. There is good reason to believe that every sensation that reaches the mind, however frequently repeated, is capable of awaking consciousness, and that only the completely reflex men- tal currents are absolutely unconscious. Thus certain tastes and Sounds may be received with full consciousness an indefinite num- ber of times. Yet with this rule the other holds good that an unfamiliar sensation most vividly arouses consciousness, and that all sensations less sharply affect the attention as they grow famil- iar. In all cases of the kind in which a sensation is seemingly our 946 The Relations of Mind and Matter. [October, received unconsciously, this is due to the activity of the attention in some other direction. But if the attention is disengaged, every sensation may produce consciousness, no matter how familiar a visitant it may be to the mind. The fact that when the mind is actively conscious in one direc- tion it may be unconscious of the operation of important move- ments previously set up within its organism, or of the reception of new sensations, seems to indicate that the volume of conscious- ness which may exist at any one time is limited. It may sink below this volume, even to complete disappearance during inac- tivity of the brain, but it cannot rise above it. And the variations in the distribution of this volume of consciousness are of the utmost interest and importance. Now it seems to diffuse itself, and a broad field of the mind is perceived, the central ideas in the field of vision being clear, while others crowd more faintly in, like dimly-seem objects which crowd in at the sides of the eye. Now it becomes concentrated, and only a few, or perhaps only a single idea is very vividly perceived if the powers of inward vision are acting with energy. And while, as a rule, sensations arrest the attention much more vividly than thoughts, this does not always hold. In some cases of mental diversion the most vivid sensations pass unperceived. This phenomenon of concentrated vision, as applied to the mind, has very important consequences. For the mind is utterly inactive except when energized by consciousness, and only that portion of it is active which is so energized. And as the activity of the mind governs the movements of the body, it follows that our voluntary actions, of whatever kind, are controlled, not by the mind as a whole, but by that portion of it which is active. This undeniable principle produces certain strange and important consequences. Ordinarily a certain number of our ideas are active, and particularly those deep-lying and firmly-based mental impressions and hereditary mental conditions which, acting to- gether, constitute what we call judgment, or common sense. But there are several normal and some abnormal states in which this condition is changed. One of these is in the case of strong emotion. As an earnest - desire fixes the eye intently upon some single object, and causes eye and mind alike to ignore what lies beyond this object, while the movements of the body are in response to the desire; so 1885.] The Relations of Mind and Matter. 9047 an energetic emotion fixes the eye of the mind upon some single thought, while all the remaining conditions of the mind fade and vanish from sight. In such a case judgment or reason no longer governs our actions, for the group of mental conditions which constitutes these faculties is dormant. In deep grief the person affected yields utterly to his sorrow, and cannot be aroused from his depression. In intense fear no powers of reason remain to control the movements. In violent anger only the*idea of revenge upon the object of that anger may remain. The furious man is, in a certain sense, irresponsible. His mind is an arrow moved by a single string. It discharges itself upon the obnoxious object, for there is no controlling force to restrain it. It is only when the paroxysm of emotion has passed away, and consciousness again spreads its revealing vision over the broad field of the mind, that other mental conditions spring into action, and deep remorse. may follow an impulsive deed which was committed while all the Springs of reason were dried up by the consuming heat of pas- sion. As to the question whether a person is morally responsi- ble for acts committed in such a state, it can only be answered, that every person is under moral obligation to bring his emotions under the control of his reason. The habit of unchecked indul- gence in emotion or passion may lead to as serious consequences as the formation of any other bad habit. : A second normal mode of mental concentration, utterly differ- ing from the above, is that known as reverie. In this the con- sciousness is not fixed upon one thought. It wanders freely from thought to thought, and its partial concentration is a result of in- activity instead of emotional energy. The mind is closed against impressions from without, and is also closed against the great mass of its internal stores, from the simple inactivity of con- sciousness. The circulation becomes sluggish. The waste of brain tissue is decreased. Only a slight degree of nerve energy flows into the mind, and only a few of its countless store of ideas- are aroused to activity. And the consciousness is not concen- trated upon these. “It flows freely over the links of association. The dreaming state is merely an intensification of this state of revery. Now the circulation is reduced to its lowest point. Ex- terior impressions, except they be very violent or very unusual, fail to affect the mind. The inner store of ideas is alike inactive. In its extreme state this produces dreamless sleep. But in a less VOL. XIX.— NO. X. 62 948 . The Relations of Mind and Matter. [October, extreme case the mind is partially active. Some oxygen visits the brain. The wasted nerve tissue is being reproduced. Conditions arise in which oxygenation feebly takes place, and the free energy of the nerve cell is given off. These conditions may arise under the influence of some impressions upon the nerves of sense, or under that of some intimate connection between a locality of the mind and a reorganized region of the brain. In either case a slight degree of energy flows into the mind, so slight that only a very limited field of thought becomes active. The results are very striking. These few active thoughts form our whole mental world. There is no force of exterior sensation or of interior judgment to control them. The most absurd conceptions seem to us to be actual facts. Its most vivid perceptions are in every case facts to the mind. Ordinarily these are sensations of out- ward objects. But where sensation is at rest the dominant idea assumes the appearance of an external reality. And where judg- ment is at rest the incongruity of an idea with actual facts may remain unperceived, though even in dreams absurdity becomes apparent, as though the judgment were partly aroused. There are other characteristics of the mental organism which aid in assimilating it to physical organisms. It impresses us as if subject to variations of temperature. Its emotional states lead to the conception of hot or cold states, and the effects which they produce are very interesting. Thus fear or terror impresses us as a chill of the mental organism. And its effects are singularly like those of cold on the body. The latter when chilled becomes sluggish, dull, torpid, strongly predisposed to sleep. Intense fear _ in animals yields similar effects. They grow paralyzed, as it were, torpid or inactive in condition, and probably with dulled sensibil- ity to pain and a general inactivity of consciousness. The condi- tion of the seemingly charmed bird is probably of this character.’ On the other hand passion is a state of heat. Its effect is to in- ‘stigate excessive activity, violent movements, vivid consciousness. _ 1 Fear, alarm, terror, horror, in their major degrees at least, frequently paralyze : all power of self-preservative action, creating a dangerous immobility o of body, with 3 ar may beget stupidity or mental n leading Seon or useless action. ” Lindsay’s Mind in the Lower mals, 11, 235- ' 1885. | The Relations of Mind and Matter. 949 Between the extreme states we have the condition of pleasure, in which the mind seems gently warmed, and of gloom or depres- sion, in which it seems similarly chilled.1 The reasoning power is most efficient in calm states, when the temperature is normal. Then consciousness is diffused and its vision extended. In the other conditions it becomes more concentrated, until, in extreme heat or chill, a single idea or feeling dominates the mind. We have not space here to consider the more aberrant condi- tions of mentality, such as somnambulism, hypnotism, insanity, &c., and the various strange phenomena which attend injury to the brain. None of them are incongruous with the idea that the mind is a distinct organism, and the brain its instrument of activ- ity. Nor can we consider the many interesting relations of thought to thought or memory to memory, and the interaction of memories which lie at the basis of the evolution of ideas. Many of these are highly interesting and peculiar, yet there is nothing _in them inconsistent with the hypothesis we have advanced. It will suffice to say that no thought ever calls up another unless they are directly or indirectly related, or associated in time or place of reception. It may be said, however, that our ideas differ i widely in their degree of fixity in the mind and influence over its movements. Below all, as the basis of the organism, lie a series of deeply-based hereditary conditions, gained during ages of mental development. These are very persistent, and strongly resist warping influences. And the effort to perform any action inconsistent with them is vigorously resisted, even though we may be very faintly conscious of the source of the resistance. The mental development obtained during youth is also deeply based, and actively resists the warping influence of later impres- sions. The later the impression in date of reception the less firmly does it seem implanted, as if these late impressions were but slight and superficial affections of the more deep-laid early Stages of development. 1 “Tn certain animals there is occasionally a ae ‘wildness of joy,’ great inten- sity of mental excitement from pleasurable emotions. Thus Darwin speaks of the ‘ madness of delight’ in a stickleback, meaning, no doubt, exhuberance of joy, or _ uncontrollable animal spirits.” Ibid, 11, 233- Thus strong pleasure seems to produce general activity of mind and body, w deep. grief or depression from any cause produces sluggishness and inactivity of con- Sciousness, just the effects which would naturally flow from states of heat or chill in a physical organism, 950 The Relations of Mind and Matter. [October, In this connection a consideration of great importance and in- terest arises. It is certainly a singular fact that in the very exact /transmission to the germ of minute features in the physical organ- ization of the parent, the mental organization is never transmitted except in its basic characteristics. Every organ of the body is reproduced, with all its powers inherent. The cerebrum is repro- duced and develops in company with the other organs. The fact that these organs are functionally copies of those of the parent proves that the reproduction is not only of material form but of the parental motor conditions. . This equally applies to the cere- brum, whose motor conditions should fully reappear in its devel- opment. Yet if these motor conditions are the powers of the mind they certainly do not reappear. In every individual a new mind has to be built up. The body, cerebrum and all, may attain its full development and the mind remain in its germinal state. Evidently it is a constituent of the individual alone, and not a something that may be hereditarily transmitted. The character of the cerebrum limits and controls the extent and direction of the „mental development, and imposes certain hereditary characteristics -n its primary phases of unfoldment, but not a trace of the spe- -cial mentality of the parents reappears in the child. This indi- cates that the mind is the property of the individual alone, in whose life it is developed, and whom it may survive. The whole physical frame, including the cerebrum, is represented in the germ, but the mental organism is never transmitted. This is cer- tainly a fact of high significance. : _.. The condition of emotion is one that seems analogous to con- ditions existing in every organism. It appears to be a state of heat or cold, strong passion, for instance, being an intensely heated state, and deep fear a state of shuddering chill. The mind has also its attractions and repulsions, and these seem to be closely concerned with its activities. Very many of our move- _ ments are directly due to drawings in some direction or towards some object, or repulsions from some object. The motives which | our movements are very frequently motives of attraction ee or distaste, and with these motives some degree of the emotional state usually exists, a slight warmth in the case of attraction and chill i in the case of repulsion. Possibly some condition of these ies is concerned in the changing relations of the mind to the and may be the motor influence by which contact is effected, 1885.] The Relations of Mind and Matter, 951 energy set free and consciousness called into existence. In this connection attention may be called to Mr. J. S. Lambard’s experi- ments on heat conditions during mental action. He found that emotion had far more influence than thought in this direction. A few minutes self-recitation of emotional poetry yielded more heat ` than several hours of deep thought. In the latter case the energy set free seems to have been employed in mind development. If the poetry was spoken less heat appeared. Here energy was used in muscle movement. The considerations here taken in regard to the conditions of consciousness, and the relations of energy to the mental organism, seem to lead to the conclusion that every organized mass, when its internal relations become disturbed by the inflow of discordant external energies, must feel some influence more or less closely allied to consciousness. But if the vividness of consciousness in any sense depends upon the mobility: of the organism, and the extent of the disturbance produced in its internal condi- tions, then it may pass through many degrees of unfoldment, from an excessively vague and generalized effect to the sharply specialized condition of human consciousness. In every case there is resistance to change. But ina rigid crys- tal the resistance is very great, while in a mobile mind it may be excessively slight, and disturbance of conditions be produced by influences of the utmost delicacy. It must be borne in mind, however, that in man consciousness accompanies action of energy on the mental organism only. Action upon the muscles, though yielding equal disturbance, is never attended by consciousness. us the peculiar conditions of substance which occur in the mental organism may be absolute requisites to this effect. It is also requisite to consciousness that the inflowing energies shall act only to modify the motor conditions of organization, not to produce disintegration, or to disseminate themselves as goien ized motions. With the lowest animals consciousness must be exceedingly vague and inactive. Their sensitiveness is undeveloped, their sense organs in embryo, the conditions to which they are exposed nearly unvarying. Most of their actions must be reflex. Yet some feeling of every new mode of impression must be expe- rienced, and this feeling attends and perhaps aids in every step of upward evolution. The frequency and activity of consciousness 952 The Relations of Mind and Matter. [October, increases as we ascend in the animal scale. And what was once conscious condition falls steadily back into the realm of the un- conscious, as higher stages of this activity arise. Yet even in lower man consciousness is dull in action and limited in range as compared with civilized man. Customary actions and thoughts tend to lose all sharpness of conscious definition, and the cus- tomary rules far more supremely in lower men and in the brute realm than in the world of civilization. By this dulling of customary sensations consciousness is con- ~ Stantly set free for superior labors. It is actively exerted in get- ting a firm grasp on every new condition presented to it. But this once gained, attention is set free and reaches outward and upward. The new acquisition sinks deep into the mind, to be recalled at intervals, and perhaps in time to become a constituent part of the mental constitution. In the case of the child learning to walk, for instance, consciousness is vividly concentrated upon its efforts. But the movement once gained the attention is set free for devotion to other things, and the motion of walking may finally be performed unconsciously. Numerous other instances of this kind might be adduced, leading up to that often quoted and extraordinary one of the nearly or quite unconscious action of the fingers of the pianist. In regard to mental labors the same rule applies. We are con- stantly exercised in observing new facts, imagining new condi- tions, forming new ideas, Each addition to our mental stores occupies the consciousness more or less exclusively until it be- comes an habitual occupant of the mind, after which the attention is released for devotion to new labors, and the idea thus gained sinks back into the fabric of the mind: It may be recalled at will, but it no longer has a despotic control of the consciousness. In this upward progress of the mind we are often inclined to believe that the superiority of higher man is intellectual only, and that n regard to acuteness of the senses he has fallen behind the sav- age. Yet this is not the case. He may have lost acuteness in respect to distant vision, or sharpness of hearing, but his sensi- =~ tiveness has grown far more diversified. He can see countless delicate shades of color and variations of form, can appreciate the most minute variations of musical tone, can distinguish delicate s of odor and taste of gece the savage is utterly incapa- ‘aad senses have y thus becom more delicate and = 1885.] A Brief Biography of the Halibut. 953 varied in their powers, and his mind responsive to a greater vari- ety of impressions. It is in his ideas, however, that civilized man so greatly over- tops the lower world of life. His mind has been for ages pushing deeper and deeper into the realm of the unknown like an eating sea that is cutting its way steadily into the land. Before it lies the unknown, stretching away into the infinite. Behind it lies the known, half or wholly buried beneath the shrouding waters of the sea. The surf line is the line of consciousness, the border between the known and the unknown. Here consciousness mines forever into the coast line of facts, letting every new-gained fact float out to come to rest on the quiet sea bottom, the stores of recent memory lying half visible in the shallow waters, while in the deep sea beyond lie the layers of ancient acquirement which have become to us hereditary capabilities, the native stuff of the mind. What new and deeper powers the senses may yet attain, what new susceptibility the mind, cannot be said. We see rising dimly and shapelessly around us new phenomena, new stuff for thought on which the mind of future man must work, and ‘ every new age may safely say to the ages of the past: “ There are more things in heaven and earth, Horatio, than are dreamed of in your philosophy.” ey" VU. A BRIEF BIOGRAPHY OF THE HALIBUT. BY G. BROWN GOODE. ee halibut, Hippoglossus vulgaris, is widely distributed through the North Atlantic and North Pacific, near the _ Shores, in shallow water, as well as upon the offshore banks and the edges of the continental slope down to the depth of at least 400 fathoms. The species has not been observed in the West- . ern Atlantic south of the fortieth parallel; stragglers have Occasionally been taken off Sandy Hook, Block island and Montauk point. It ranges north at least to Cumberland gulf, latitude 64°, to Holsteinborg bank in Davis’ strait, and as far as Disko and Omenak fiord, latitude 71°, on the coast of Green- land, five or six degrees within the Arctic circle. It occurs along the entire west coast of Greenland, and is abundant about * Iceland and at Spitzbergen, in latitude 80°. No one knows _ to what extent it ranges along the European and Asiatic shores 954 A Brief Biography of the Halibut. (October, of the Arctic ocean, but it has been observed on both sides of the North cape, in East and West Denmark, and from the North cape, latitude 71°, south along the entire western line of the Scandinavian peninsula, in the Skager Rack and Cattegat, though not, so far as I can learn, in the Baltic sea. The halibut is occasionally seen in the southern part of the North sea and in the English channel, but never, in the Eastern Atlantic, south of latitude 50°. There is yet some question whether it is found in the south of Ireland, though some of the largest individuals ` recorded from Great Britain have been taken in the Irish sea, off the Isle of Man. On the Pacific coast the halibut, which has besi shown by Dr. Bean to be identical with that of the Atlantic, ranges from the Far- allones islands northward to Bering straits, becoming more be dant northward. “Its center of abundance,” says Bean, “is in the Gulf of Alaska, particularly about Kodiak, the Alexander archipelago and the Shumagins. Large halibut are numerous about the Seal islands, but the small ones have been killed by the seals. I have heard from good authority of their capture as far north as Saint Lawrence bay, near East cape, in Siberia. It has several times been reported from off the heads of Marcus bay, Siberia.” It is occasionally taken off San Francisco and about Humboldt bay. In the Straits of Fuca and in the deeper chan- nels about Puget sound it is taken in considerable numbers. A large halibut bank exists in the mouth of the Straits of Fuca, about nine miles from Cape Flattery in a north-westerly direc- tion, and the capture of this fish is an Soren industry to the coast Indians, The halibut is emphatically a cold-water species. That it should ‘range nine or ten degrees farther south on the American than on the European coast, is quite. in accordance with the general law of the distribution of fish-life in the Atlantic; indeed, it is only in winter that halibut are known to approach the shore to -~ the south of Cape Cod, and it is safe to say that the temperature _ of the water in which they are at present most frequently taken is never, or rarely, higher than 45°, seldom above 35° and most often in the neighborhood of 32°. Its geographic range cor- responds closely to that of the codfish, with which it is almost riably associated, the cod is, however, less dependent upon the ce of very cold water, and in the Western Atlantic is found 1885.] A Brief Biography of the Halibut. 955 four or five degrees—in the Eastern Atlantic at least two—nearer the equator, while the range of the two species to the north is probably, though not certainly, known to be limited relatively in about the same degree. In the same manner the halibut appears to extend its wanderings further out to sea, and to deeper and colder waters than the cod. Although observations on this point have necessarily been imperfect, it seems to be the fact that cod are very rarely found upon the edge of the continental slope of North America beyond the 250-fathom line, while halibut are present in abundance upon the outer slope. The name of this fish is very uniform in the regions where it is known, though, of course, subject to certain variations in the languages of the different countries, for its characteristic features are so unmistakable that it is rarely confounded with other spe- ` cies. The only fish for which it is mistaken seems to be the turbot of the European coast, with which it sometimes inter- changes names. It is said that in Scotland the halibut is fre- quently called the turbot, and Yarrell has expressed the opinion that in instances where it has been claimed that halibut*had been taken in the south of Ireland the turbot was the species actually referred to. “Halibut” and “holibut” are words which are as old as the English language. In Germany the fish is called “heilbutt” or “heiligebutt ;” in Sweden, “ hillefisk” or “ hälleflundra,” while in Holland it is known as the “ heilbot.” In studying these names it should be borne in mind that “but” or “bott” is only another word for flounder or flat fish, and that the English, Dutch, German and Scandinavian prefixes to this word or the equivalent word flounder are presumably of the same | meaning. A false derivation has been imagined for the name, which is exemplified in the German word “heiligebutt” just mentioned, and also in an English spelling, which is sometimes encountered, “ holybut.” This idea is without foundation, for the halibut has never been reverenced more highly than any other Species of flat fish, and the derivation is as fanciful as “ haul-a- _ boat,” which our New England fishermen have frequently assured me was the proper name, having reference to the size and strength of the fish. The true derivation of the word may best be understood through a study of its Scandinavian names, from _ which it appears that the prefix has reference to the holes or deep 956 A Brief Biography of the Halibut. [October, places at sea in which the fish is found, and that the name simply means “a deep-sea fish,” or “a deep-sea flounder.” The general distribution of the halibut having been sketched in outline, it may, perhaps, be appropriate to discuss more fully the range and abundance of the fish upon the coast of North America, and to describe the regions where it is sought by American fishing vessels. Halibut are taken very abundantly on Holsteinborg bank, at the southern entrance to Davis’ strait, latitude 67° north and longitude 54° to 56° west, where several Gloucester schooners have in past years obtained large cargoes of salted fish. In Etzel’s “ Gronland,” it is stated that halibut are taken chiefly in the southern part of North Greenland, and everywhere on the shoals among the islands in the district of Egedesminde, especially about Agto, Riskol and Ikerasak, in latitude 68°, and somewhat less near Disko, in latitude 76°. They are captured most abundantly in the spring and fall. They are even taken, at greater depths, as far north as Omenak, in latitude 71°. Ina later work Rink asserts that “the Netarnak or larger halibut is found on the banks, as well as in different places outside the islands, up to 70° north lat- itude, in depths of from thirty to fifty fathoms.” In the same later work Rink remarks that halibut are plentiful in the fall about Egedesminde, and especially about Agto, the southernmost out- post of North Greenland. Etzel goes on to state, regarding the occurrence of halibut in South Greenland, that in July and Au- gust they are taken on the outer coast and among the islands at depths of thirty to fifty fathoms, while in winter they frequent deeper regions and are but seldom seen. Rink narrates that in 1809 there were taken among the islands off Godthaab (64° 8’ north latitude) 2000 halibut, and that in a single half-day two boats took over one hundred. They are rarely taken in the dis- trict of Julianshaab, in latitude 60° 43’ north. Peter C. Sutherland, writing of Riskol bank, in 1850, stated that halibut were then very abundant in that locality, and that the = cod-fishing vessels which visited Davis’ strait every season used _ them to bait their hooks, though the supply far exceeded the _ demand for this purpose. _ Sutherland narrates that on the return of the Penny expedition, in 1851, when crossing the Arctic circle, in longitude 53°, the ilors put over lines baited with pork and hooked a cod anda i wa at sea depth of forty fathoms. 1885. ] A brief Biography of the Halibut. 957 The most northern occurrence of the halibut on the western side of Davis’ strait is that recorded by Mr. Ludwig Kumlien, naturalist of the Howgate expedition, who saw a large individual taken by the Eskimos off the mouth of Davis’ straits, near lati- tude 64° north. Richardson, in the Fauna Boreali-Americana, speaks of the occurrence of the species on the Greenland coast, but seems to have no authentic information of its having been observed even K3 as far north as Labrador on the opposite side. There is no reasonable doubt that the halibut is found along the entire eastern coast of Labrador, though there is no other published record of its occurrence north of Red bay, in the Straits of Belle Isle, near latitude 51° 40’ north, where it was observed by Mr. Horatio R. Storer, several individuals having been taken during his stay at that place in the summer of 1849. It is abundant in certain parts of the Gulf of St. Lawrence, especially the island of Anticosti, and is also found along the entire -coasts of Newfoundland and the eastern shores of Nova Scotia. In June, 1878, the schooner G. P. Whitman, of Gloucester, caught a fare of halibut in two to twelve fathoms of water near 4 Green point, Newfoundland. The crew said that they could see the fish lying on the bottom in shallow water. Capt. George Olsen, schooner Proctor Brothers, arrived at Gloucester, August 2, 1880, with 22,000 pounds’ weight of fresh halibut from Anticosti. He reported halibut plenty then at the western end of the island close inshore—within half a mile; he _ Saw the halibut sporting near and on the surface; he found they would not bite, as on the banks, at halibut bait, and since fresh __ herring or capelin could not be obtained, could only get a partial = trip of halibut. They were good fish, weighing sixty to eighty w pounds. - According to M. H. Perley halibut are found in the Bay of Fundy up to its very head, where they are taken in summer in Cumberland bay, near the light-house off Apple river, and also in est bay. He states that they are also found on the south shore _ of the Bay of Fundy, and abundantly from Cape Split to Brier island, as well as in the Annapolis basin. Perley’s report was pre- _ Pared in 1852, and there is no evidence of diminution in that _ region since he wrote. Mr. J. Matthew Jones tells me that halibut are occasionally 958 A Brief Biography of the Halibut, [October, taken at Five islands in the Basin of Minas, but that this is of rare occurrence. I am indebted to Captain Ashby for the following facts about the southern limits of the distribution of the halibut: He has never known them to be found south of Sandy Hook, where large ones are occasionally taken in winter. In May, 1876, the schooner Cartwright, fishing ten miles south-east of Montauk point, caught many halibut, In February, 1876, some Noank _ smacks caught a few halibut about eight miles from land, off the south-east point of Block island. Within the last.forty years one or two halibut have been taken off the outer shore of Fisher’s island. He has never known any to be taken in Long Island sound. Halibut are sometimes taken in three fathoms of water among the breakers off Nantucket, in “ blowy weather.” Forty years ago they were abundant about Gay head and Noman’s land. There has been no systematic fishing there lately, but some individuals have probably been taken. The local papers chronicled the capture, on May 1, 1876, off Watch hill, Rhode Island, of an eighty-pound halibut, the first taken in that locality for many years. A halibut is occasionally taken along the shores of Maine and Massachusetts, but so seldom that a capture of this kind by one of the inshore fishermen is always mentioned in the local papers. Abundance.—Half a century ago the halibut was extremely _abundant in Massachusetts bay, and striking stories of their great plenty and voracity are narrated by some of the early fishermen of Cape Ann. Of late years, however, few have been found ex- cept in deep water on the off-shore banks. Captain Chester Marr says that in early days halibut were ex- ceedingly abundant on George’s bank. He has seen a “ solid = school of them as thick as a school of porpoises” feeding on © “Jant.” At another time “ the whole surface of the water as far _ . as you could see was alive with halibut; we fished all night and = we did not catch a single codfish. The halibut would not let _ the hook touch the bottom ; we caught 250 in three hours; the crews of some vessels vould go and cut the fins off the fish and let their bodies go. No wonder that they were broken up. We thought they were always going to be so. Never made no lations s that we were going to break them up. The southern x 1885.] A Brief Biography of the Halibut. 959 side of George’s was a kind of ‘ mother-place’ for fishing hali- but.” There was no great abundance of halibut on George’s after 1848. The abundance of the species on the off-shore banks before the over-fishing took place is almost beyond credence. The fol- lowing is selected from a large number of instances of fishermen’s successes: The schooner Mary Carlisle, of Gloucester, made nine trips to the banks in 1871. Her catch was 350,188 pounds of halibut and 58,759 pounds of codfish ; her net stock amounted to $17,275.53 for about eleven months’ work, from December 27, 1870, to November 21, 1871. On one trip in the spring she brought in 58,553 pounds of halibut and 6900 pounds of codfish, her net stock reaching the sum of $4738.75, and her crew sharing $236.25 each from a voyage of thirty-four days. She had ten men in her crew, each of whom during the season shared $858.62. In three years this vessel stocked a total of $46,871, divided as follows: 1869, $17,549; 1870, $12,047; 1871, $17,275.53. The presence of so important a food-fish in America did not long escape the observations of the early English ex- plorers. Captain John Smith, in his History of Virginia, wrote: “There is a large sized fish called hallibut, or turbut: some are taken so bigg that two men have much a doe to hall them into the boate; but there is such plenty, that the fisher men onely eat the heads & finnes, and throw away the bodies: such in Paris would yeeld 5. or 6. crownes a peece: and this is no dis- commodity.” ' The halibut is surpassed in size by only three fishes on the Atlantic coast—the swordfish, the tunny and the tarpum. It is said, by experienced fishermen, that there is a difference in the size of the two sexes, the females being much the larger; the male, they tell us, rarely exceeds fifty pounds in weight, and is ordinarily in poor condition and less desirable for food. The average size of a full-grown female is somewhere between 100 and 150 pounds, though they are sometimes much heavier. Captain Collins, who has had many years’ experience in the Glou- ` cester halibut fishery, assures me that he has never seen one which would weigh over 250 pounds, and that a fish weighing over - 250 pounds is considered large. There are, however, well authen- ticated instances of their attaining greater dimensions. Captain _ Atwood, in a communication to the Boston Society of Natural 960 A Brief Biography of the Halibut. [October, History in 1864, stated that the largest he had ever taken weighed, when dressed, 237 pounds, and would probably have registered 300 pounds when taken from the water. In July, 1879, the same reliable observer saw, at Provincetown, two individuals taken near Race point, one of which weighed 359 pounds (302 pounds when dressed), the other 401 pounds (322 pounds when dressed). There is a tradition in Boston that Mr. Anthony Holbrook, one of the early fish-dealers of that city, had in his possession a hali- but, taken at New Ledge, sixty miles south-east of Portland, which weighed over 600 pounds. This story, which is recorded by Storer in his “ Fishes of Massachusetts,” Captain Atwood be- lieves to be untrue. Halibut weighing from three to four hun- dred pounds, though unusual in comparison with the ordinary size, are by no means rare. I have before me records of ten or twelve such fish captured on the New England coast during the past ten years. Nilsson, has mentioned the capture, on the Swedish coast, of an individual which weighed 720 pounds. There are stories of halibut ten feet in length; a fish weigh- ing 350 pounds is between seven and eight feet long and nearly four feet in width. The largest halibut are not considered nearly so good for table use as those of less than 100 pounds weight. A fat female of eighty pounds is, by good judges, con- sidered to be in the highest state of perfection, while males - are not so highly esteemed. Small halibut, known as “chicken halibut,” ranging from ten to twenty pounds, are much sought after by epicures, and bring a high price in the New York and Boston markets. They are, however, comparatively rare, and those weighing ten pounds or less are rarely seen; the smallest recorded from our coast was about five inches in length, and was taken by Professor Verrill in a dredge-net in the Strait of Canso. The halibut of the Pacific are apparently similar in dimensions to those of New England. Mr. Anderson, inspector of fisheries for British Columbia, states that in the waters of Puget sound _ they attain a weight of 200 pounds. ~ The wholesale dealers of Gloucester, in buying fresh halibut _ from the fishermen, recognize two grades ; one, which they call “gray halibut,” they consider to be of inferior value, and pay 4 lower price for. The gray halibut are distinguished by dark s or blotches upon the under side, which in the most 1885. | A Brief Biography of the Halibut. g6r marketable fishes are pure white. Almost all the largest halibut are classed among the grays, Fishermen claim that there is no actual difference between the gray and white fish, and it is a fair question whether they may not be right. Migrations.—It is useless to attempt to describe at this time the migrations of the halibut from place to place; although much information has been received upon this subject, the problem requires long and careful study. Captain Benjamin Ashby, of Noank, Connecticut, who is familiar with the fisheries south of Cape Cod, informs me that halibut frequent the deepest water in the spring and fall, and that in May and June they come up in the shoal water, in sixty or seventy fathoms, while in July they begin to go out again into deep water, and by the latter part of the month are on the way into the gully near the north-east part of George’s bank. Captain Joseph W. Collins, undoubtedly the best authority upon the subject, briefly expresses his views as follows; “ Halibut are found in the deep water—say from 100 to 250 fathoms in depth—on the edge of all the banks from George’s to the Grand bank the year round. Sometimes, however, they seem to be more numerous in comparatively shallow water in the winter and early spring. This was the case in the winters and springs of 1875-’76. and 1876-77, as well as in the year preceding, but in 1878 there was no great catch of halibut in less than 100 fathoms on. any of the banks. The great schools that were found in the western part of the Grand bank in February and March, 1876- and 1877, appeared to be migrating. The fish that were found to the south of latitude 44° north were mostly small-sized white halibut. They went off the bank into deep water, and nobody knew what became of them. Those that were caught to the north of this parallel were mostly large gray fish, and were _ traced as far as Saint Peter’s bank. These are possibly the same fish—they are certainly the same kind of fish—that struck in on the western coast of Newfoundland and in the summer months in. pursuit of capelin.” _ Capt. George A. Johnson states that the large halibut generally frequent the outer and deeper part of the banks, while the little “bull fish” lie inside, on shallower ground, and are caught on the _ inner end of the trawl lines ; sometimes, however, the large halibut: also come up on the shallow grounds. 962 A Brief Biography of the Halibut. [October, On the coast of Newfoundland, Anticosti and Labrador, in summer, halibut frequently run inshore after capelin. When in shallow water near the shore they are usually wild and very active. Within eight years the fishermen have extended their fishing much farther out to sea; previous to that time the greater part of the halibut were taken on top of the Grand bank in thirty to fifty fathoms of water, but after the beginning of April the fish went elsewhere, and the fishermen lost sight of them. They soon learned, however, to follow them down the slopes of the banks, though before 1876 they had rarely fished in water deeper than seventy to ninety fathoms. Since that time, as has already been stated, fishing has been carried into twice or three times that depth. All that can at present be said in explanation of their movements is, that they occur in great schools, which consume the available food in any one locality, and are soon obliged to shift their position to some other place where they can find fresh supplies. It does not seem possible that their migrations can be caused by conditions of temperature or are in connection with their breeding habits. During the breeding season the schools sometimes remain for months in one locality, and these places are generally of limited extent. While spawning but little if any food is found in their stomachs. Food.—They are large-mouthed, ee toothed and voracious, and though especially adapted for life upon the bottom, doubtless feed largely upon crabs and mollusks. They are especially fond of fish of all kinds; these they waylay, lying upon the bottom, in- visible by reason of their flat bodies, colored to correspond with the general color of the sand or mud upon which they rest. When in pursuit of their prey they are active, and often come quite to the surface, especially when in the summer they follow the capelin to the shoal water near the land. They feed upon skates, cod, haddock, menhaden, mackerel, herring, lobsters, flounders, sculpins, grenadiers, turbot, Norway haddock and bank clams. Captain Ashby tells me that common flounders and flat fish are among their most favorite food; these they follow upon the shoals of George’s and Nontickes lying in wait for them on the sand-rips and seizing them as they swim over. He has seen half a bushel of flat fish stowed away tightly in the stomach of a single halibut. He has often seen halibut chasing at fish over the surface of the water. About Cape Sable their 1885. ] A Brief Biography of the Halibut. 963 favorite food seems to be haddock and cusk. He has seen eight or ten pounds of haddock and cod taken out of one of them. — When they are on the shoals they are sometimes filled with flat fish, haddock, cusk, sculpin and herring, but when in deep water he has found very little food in them. They eat crabs and other crustaceans, but shells are rarely found in their stomachs, except those of clams and mussels. Captain Hurlbert tells me that when the vessels are dressing ` codfish on the Grand banks, and the backbones and head are thrown overboard, these are frequently found in the stomachs of halibut taken in the same locality. Mr. William H. Wonson, of Gloucester, has seen live lobsters six inches long taken from the stomach of a halibut. Captain Mar states that they feed on whiting, mackerel and herring. He remarks: “Halibut will drive off any kind of fish and take charge of the ground.” At the meeting of the Boston Society of Natural History, in 1852, Dr. W. O. Ayres stated that he had seen a block of wood, a cubic foot in dimensions, taken from the stomach of a halibut, where it had apparently lain for a long time. Capt. George A. Johnson found an accordeon key in one of them. Olafson, in 1831, studying them on the coast of Greenland, found not only pieces of iron and wood in their stomachs, but in one indi- vidual a large piece of floe ice. Captain Collins has observed that they often kill their prey by blows of the tail, a fact which is very novel and interesting. He described to me an incident which occurred on a voyage home from Sable island in 1877: “The man at the wheel sang out that he saw a halibut flapping its tail about a quarter of a mile off our starboard quarter. I looked through the spy-glass and his statement was soon verified by the second appearance of the tail. We hove out our dory and two men went in her, taking with them a pair of gaff-hooks. They soon returned bringing not only the halibut, which was a fine one of about seventy pounds weight, but a small codfish which it had been trying to kill by striking it with its tail. The codfish was quite exhausted by the repeated blows, and did not attempt to escape after its enemy had been captured. The hali- but was so completely engaged in the pursuit of the codfish that it paid no attention to the dory, and was easily captured.” The observations of the halibut fishermen are full of interest VOL. XIX.—NO. X. 63 964 A Brief Biography of the Halibut. [October, to the naturalist, and it is from them that we derive all our knowl- edge of the habits of the animal while feeding. The halibut, fol- lowing in after the schools of capelin which visit the shores of Western Newfoundland, Southern Labrador and the islands of Anticosti and Miquelon to spawn, have often been found in great abundance in very shallow water, not above five to ten fathoms deep. Fishermen who have watched halibut under such circum- stances, and have been able to see them perfectly well in the clear water, state that these fish exhibit marked peculiarities in biting at baited hooks on a trawl. The halibut will advance to the bait, apparently smell of it, and then retreat four or five feet from it, always lying on the bottom, head toward the bait, as if watching it. After repeating this performance several times—generally three or four—the fish seems to make up its mind to eat the bait, and suddenly darting toward it, swallows it down with a gulp. The George’s hand-line fishermen believe that halibut often strike the baited hooks with their tails. It is not uncommon on board a George’sman to hear a fisherman remark: “ There’s a halibut around; I felt him strike my gear.” When a halibut has announced his presence in this way it is scarcely necessary to say that every effort is put forth by the fisherman to attract the fish to his hooks, and if a man is sufficiently skillful he generally suc- ceeds in capturing the fish. There is much rivalry in a vessel’s crew when it is known that halibut are on the ground where she is lying, and every known device is adopted to entice the fish to bite at the hooks. Strips of newly-caught haddock, with fresh blood still on them, are con- sidered the best bait. Two, three, or more of these are put on a hook, which is passed through the thickest end of the strips, while the pointed ends of the bait are left to float about in the = water. Where there is a tide running these closely resemble the movements of a small fish. The hooks are usually “pointed” with herring bait. After the bait is on the hooks many fishermen add (as they believe) to its attractiveness by mopping it in the slime = of a halibut, if one has been previously caught. This is done by _ wiping the baited hook back and forth over a halibut. The lure _ thus prepared, the fisherman lowers his apparatus to the bottom, and by a skillful manipulation tries to induce the fish to bite. Som he will let the tide sweep his “gear” along the bot- ~ 1885.] A Brief Biography of the Halibut. 965 tom, and again he will endeavor to give his baits the appearance of life by slowly pulling them up a short distance from the ground. If he finally succeeds in hooking a halibut, all his art is required to bring the fish to the surface and land it safely on deck. If it be a large fish it almost invariably makes a desperate fight to escape. It may, perhaps, come up easily for ten or fifteen fathoms, when it suddenly takes a plunge downward. Surge! surge! goes the line through the hands of the fisherman, who knows very well that he must “ play” his fish or else his line will be snapped like pack thread. This operation may be repeated several times, and it is not uncommon for a large and particularly “wild” halibut to go almost to the bottom after having been hauled nearly to the surface of the water. At last the fish is alongside, and the shout of “ Gaffs! gaffs here!” brings two or three of the nearest men to the side, armed with long-handJed | gaffs. If the fish is exhausted the gaffs are quickly hooked into his head and he is dragged unceremoniously over the rail and falls with a heavy thump on deck, which usually resounds with the strokes of his powerful tail until he is stunned by repeated blows with a killer. If the halibut is still active when he comes $ alongside, much dexterity is required to gaff him. He makes desperate attempts to escape, and thrashes the water into foam with his tail. When the fish is on deck and. killed, his captor cuts his mark in a conspicuous manner, generally on the white surface of the halibut, which is the underneath portion when the fish is in the water, but is invariably turned upward after it is taken on deck; this method being adopted to prevent the blood from settling on that side and thus making the fish look dark colored or gray. The George’s fishermen frequently bleed their halibut by making 4 a cut across the tail. Halibut caught in shallow water are exceedingly active, and frequently make a hard fight. When a fish of 100 to 200 pounds weight is raised from the bottom on a trawl, he usually starts off at great speed, making the dory spin around in his effort to escape. Of course he cannot run far in one direction, for the _ Weight of the gear is too much for him to drag over the bottom. After a while he is sufficiently tired out to be hauled alongside of the dory, and if the fisherman is expert enough to hit his fish two or three smart raps over the nose with a “ killer,” the halibut 966 A Brief Biography of the Halibut. ' October, succumbs and is pulled into the boat. It is often the case, how- ever, that considerable difficulty is experienced in effecting the capture of a large fish, and it is by no means an unusual circum- stance for one to escape. A fisherman related to me an incident which he witnessed in the shallow water near Miquelon beach, Newfoundland. Two men were out hauling a trawl in about seven fathoms of water, a short distance from the vessel. They worked along quietly for a while, when suddenly the dory started off at a tremendous speed, towed by a big halibut which had been started from the bottom, and which, in its efforts to escape, darted about wildly, pulling the boat after it and careening her at a considerable angle. By dexterous management it was, after a while, brought to the sur- face ; the man aft quietly pulled up on the ganging until the fish broke water, when an iron gaff was driven into its head. The doryman had made the mistake of gaffing his fish before it was stunned, and as a result, no sooner was the gaff in the halibut than the latter made a tremendous splurge, twisted the implement out of the fisherman’s hand, and, getting a fair start, made a run to the bottom. Another quarter of an hour was required to again get it alongside of the dory. This time there was no gaff, and to serve in its place the doryman had cast off the trawl anchor from the buoy-line. When he got the halibut’s head above water he drove the fluke of the sixteen-pound anchor into the fish, which he made sure he would hold that time. But he was mistaken. The halibut, as before, escaped, taking with it the anchor, almost pulling the man out of the boat, which was nearly capsized, and going off with the hook, too, which this time it tore from the trawl. The halibut, in its turn, is the prey of seals, of the white whale and of the various large sharks, especially the ground shark, or sleeping shark, in the stomachs of which they have sometimes been found ; their sides, I am told by Captain Collins, are often deeply scarred, probably by the teeth of the sharks, or in their aie: lives by mouths of larger individuals of their own kind. _ Spawning—There is great diversity of opinion regarding their : speinaing season. Some fishermen say that they spawn at Christ- ‘mas time, in the month of January, when they are on the shoals. Others declare that it is in summer, at the end of June. Capt. A Johnson, of the schooner Augusta H. Johnson, of 1885. ] A Brief Biography of the Halibut. 967 Gloucester, assures me that halibut “ spawn, just like the human race, at any time of the year.” In April, 1878, he was fishing on Quereau bank and found large and small halibut, the large ones full of spawn. In May he was on Le Have bank, where he found only small male fish full of milt; in June he was on Le Have again, fishing in shallow water, where he found plenty of “ small bull fish, with their pockets full of milt;” in July he was again on Quereau bank, where he found a school of small and big male and female fish, all apparently spawning or ready to spawn, “with milt and pees soft ;” in August he was on the outer part of Sable island, where he found females full of spawn. Captain Ashby, speaking of the halibut on George’s banks, States that roe is always found in them in May and June. The roes of a large halibut caught by him in 1848 on the south-west part of George’s, and which weighed 356 pounds, after it had been - dressed and its head removed, weighed 44 pounds. He states that the halibut in this region have spawn in them as late as ‘Connecticut vessels continue to catch them, or until September. He has seen eggs in halibut of twenty pounds weight, and thinks they begin to breed at that size. The spawn of the halibut is a favorite food of the fishermen of Southern New England, though never eaten by those of Cape Ann. Captain Hurlbert, of Gloucester, tells me that on the Grand banks of Newfoundland the spawning halibut school used to come up in shoal water in forty or fifty fathoms. In August, 1878, he found many with the spawn already run out. At that time sev- eral Gloucester fishermen reported that the halibut on Le Have and Quereau banks were full of spawn. Captain Collins told me that in July and August, and up to the first of September, they are found here with the ovaries very large, and are often seen with the ova and milt exuding. The ovaries of a large fish are too heavy to be lifted by a man without considerable exertion, being often two feet or more in length. At this time very little food is found in their stomachs. In September, 1878, the Fish Commission obtained from Captain Collins the roes of a fish weighing from 190 to 200 pounds, taken by the schooner Marion on the 13th of the month on Quereau bank. This fish was taken at the depth of 200 fathoms, and the temperature of the water was roughly recorded at 36° F. These ovaries were put into a basket with ice and brought to the laboratory of the Fish Com- 968 A Brief Biography of the Halibut. [ October, mission, where they were found to weigh seventeen pounds two ounces. Part of the eggs were nearly ripe, and separated readily, while others were immature and closely adherent to each other. A portion of the roe, representing a fair average of the size of the eggs, was weighed, and was found to contain 2185 eggs; the weight of this portion was two drams. The total number of eggs was from this estimated to be 2,182,773. It is not yet known whether the eggs float or rest upon the bottom, nor is it known how long is the period of incubation, nor what is the rate of growth of the fish. As has already been mentioned, young fish are very unusual; the smallest ever seen by Captain Ashby in Southern New England was taken on Nantucket shoals, and weighed two and a half pounds after it had been eviscerated. Abnormal individuals—* Left-handed halibut” are sometimes taken. Perhaps one out-of five thousand is thus abnormal in its form, having the eyes upon the left rather than upon the right hand side of the head. Halibut with dark spots or patches on the under side, of the same dark color as the back, are occasionally taken. These are called by the fishermen “ circus halibut.” They are generally of medium size and thick, well-fed fish. The history of the halibut fishery has been a peculiar one. At the beginning of the present century these fish were exceedingly abundant in Massachusetts bay. From 1830 to 1850, and even later, they were extremely abundant on George’s banks; since 1850 they have partially disappeared from this region; the fishermen have recently been following them to other banks, and since 1874 out into deeper and deeper water, and the fisheries are now carried on almost exclusively in the gullies between the off shore banks and on the outer edges of the banks in water 100 to 350 fathoms in depth, The species has in like manner been driven from the shallow fishing grounds on the coast of Europe; - there is, however, little reason to doubt that they still are present in immense numbers within easy access off the British and Scan- dinavian coasts, and that a good fishery will yet grow up when __ the fishermen of those countries shall have become more enter- prising. _ A Prophecy—tin the year 1879 there were forty vessels, of : 168 tons, from Gloucester, Mass., employed exclusively in the ; halibut fishery; also vessels halme from New London and ` eastern end of tore island are employed, except during the 1885.] Traces of Prehistoric Man on the Wabash. 969 winter months, chiefly in the capture of halibut, which they carry to New York. These vessels, however, take also a considerable quantity of codfish. In addition to the Gloucester vessels already mentioned, which fish for halibut throughout the year, there were eight vessels, of 647 tons, which fished for halibut in the winter season and engaged in other fisheries, generally the cod fishery, from May to November. The vessels of the George’s fleet, though their chief object is the capture of cod, take considérable quantities of halibut, which are brought to Gloucester fresh ; a few also are sometimes taken by the Western bank cod fleet, and a still smaller quantity by the Boston market fleet. In 1879, and probably in 1880, there were a few small vessels on the coast of Maine which engaged in the fresh-halibut fishery for three or four months in the summer, carrying their fish chiefly to Portland. The total catch of hali- but on the New England coast for 1879 is estimated at 14.637,- 000 pounds, distributed as follows: Gloucester halibut fishery . 8,300,000 Gloucester vessels fishing in winter only . 1,000,000 mew York halibut Catchers. 005 7.4 s.40<5 cous arahi 3,000,000 Gloucester, George’s fleet (incidental)... 2,000,000 Western bank cod vessels (incidental). ... 37,000 Small vessels on the coast of Maine and Massachusetts........ 300,000 Total 14,637,000 In 1885 the halibut fleet of Gloucester is reduced to one-fourth of its former size, and the total catch is estimated at from three to five million pounds, It is evident that within a few years the American off-shore halibut grounds will be so depleted that the fresh-halibut fishery on our coasts will be abandoned. We shall then derive our chief supply from the waters of Greenland and Iceland, where several vessels go each year to bring back cargoes of salt “ flitches.” Halibut will come into our markets only in a smoked condition, and the species will be as unfamiliar in our fish-markets as it is in — those of the old world. The life-history of the species must be recorded now, for it can never be made so completely hereafter. This is the writer's excuse for having presented in this place so full a biography of the halibut. — om TRACES OF PREHISTORIC MAN ON THE WABASH. BY JOHN. T. CAMPBELL. p oone the year 1884 I was employed as civil engineer for the construction of a levee from the mouth of Big Raccoon Creek on the east side of the Wabash river, which is the west boundary of Parke county, Indiana. The levee was built as close to the river bank as practicable, and was aimed to be the height 970 Traces of Prehistoric Man on the Wabash. (October, of the highest bottom land, though this is about seven feet below ‘the highest floods, such as occurred in the summer of 1875 and winter of 1883. There is one very high bottom about four and a half miles south of the mouth of Raccoon creek, locally known as Blue Grass landing. Forty to fifty years ago this place was well known to flat and steamboat men. The Wabash was then the great commercial thoroughfare for all this country, and this being a good landing, backed by good farms near by, and covered with the heavy, green carpet of blue grass (Poa pratensis), was also one of the most beautiful spots on the river. Here it was, ac- cording to Dr. Collett, State geologist, report of 1879, that the Kentucky soldiers of Harrison’s army, while marching from Fort Harrison to Tippecanoe to fight the Indians there, found the original Kentucky blue grass, and on their return gathered and carried home the seed, which is now an important article of Ken- tucky commerce. The old settlers had a tradition that this spot (a quarter of a mile long up and down the river) was an ancient Indian camping ground. What reasons they had for so believing I never learned. But during my frequent surveys and inspections of the work be- fore mentioned, I had abundant reason to know that such was the fact. The surface of the ground, however, indicates nothing of the kind. The place is not overflowed more than once in seven years on the average. The bottoms are over a mile wide, and much the lowest back next the hills. The few floods that have overflowed this high bank during recent years (I mean histori- cally recent, not geologically) have flowed nearly square across it, and since ‘the timber has been cut away, has washed small channels from four to ten feet deep toward the eastern hills. These channels are deepest next to the river, growing shallower till they disappear at distances from one-quarter to three-quarters of a mile from the river. In the bottom of these channels Mr. Sam- uel D. Hill, drainage commissioner of the county, was the first to ~ Observe little heaps composed of stones about the size of apples | Or potatoes, and about a bushel in quantity. They were in the more recently cut channels, the current being sufficient to remove _ the bottom earth but not enough to disturb the order of the stones. I said the stones were in heaps; this is not quite cor- rect. They were about three layers deep and two and a half to three Jide half feet wide, and slightly oval in shape. They were 1885. ] Traces of Prehistoric Man on the Wabash, 971 underlaid with one to three inches of charcoal, and on top of the stones, and scattered down streamward from them, were mussel shells and a few bones of small animals too much decayed and fractured to be identified ; but the leg of a crane or pelican near by was so well preserved that every joint of the foot to the nail was in perfect shape. But on handling it soon crumbled into lime dust. So it was with the mussel shells, except a half shell, which was as fresh as if taken recently. The stones were such as lie at the upper end of the river bars, mostly crystalline, some gray, others blue. All had originally been smooth, water-worn, but were broken into angular fragments, segments, cubes and zones. I put the pieces together in several instances and with them completed (filled out) smooth, rounded water-worn stones. All had a dark smoky look as if having been burned in the fire, I should think that those we examined and those we saw without special examination would amount to seven cubic yards. One piece of white limestone, about the size and much the shape of a brick, when I touched it I found to be slaked into lime. The charcoal underneath the layers of stones on the coal, their smoky appearance, their peculiar fractures, all show that they had been placed on a fire. The mussel shells and bones on and near these stones indicate that the purpose of that fire was for cooking. It is very difficult to open the shells of a live mussel (Wabash oyster), but when baked on hot rocks they easily yield. I say these stones were found in heaps. Such was true of five separate piles or heaps, from which I infer that all the stones found in the largest and oldest channel had been once so piled, as they were smoked and broken in the same way, and seemed to amount in quantity to ten wagon loads or about seven cubic yards. - When were these stones piled and used as above described ? — “That is the question.” This place or piece of bottom is very seldom overflowed now, consequently it is building up from sedi- mentation very slowly. The heaps, or piles of stones were found about five feet beneath the present surface, and on the present surface bur oak trees are standing that are two hundred and fifty years old. These grew from acorns borne by a previous generation of trees, and the acorns from which they grew, judged by the sur- face roots of the trees, were not more than two feet beneath the Present surface of the ground. The under side of the surface roots would be a little below the position of the acorn when the 972 Editors Table. [October, tree started. It is my judgment that not less than five hundred years have elapsed since these stones were covered by sedimen- tation, and I should think the time would not exceed one thou- sand. As stone axes, knives and arrow-heads were searched for among these stones and not found, I think they were not used by the people who used the stones for cooking. Among so many stones of that kind, and in a camp, some tool would have been dropped. Such tools are found on the present surface in every neighborhood about here. If this should prove correct (that none were used by this people), it would prove that the stone axe is not so old as we have heretofore thought it to be. Or, did these people take extra care of their tools? Then why did the much later Indians having equal use for heir tools, drop them all over the country ? Or, were these suddenly abandoned on the intro- duction of steel tomahawks, knives and fire arms ? There are no Indian mounds within fifty miles of this camp. It was, therefore, hardly the work of the mound-builders. My ancestors for three generations were pioneers, and well acquainted with Indian character and customs from 1760 to 1820, and from Massachusetts to the Wabash, and while I have heard very many of their Indian stories I have never heard of their seeing any- thing like what I have described, nor do I remember to have seen it described in any account I ever read. Is this a new fea- ture of an ancient subject? or am I illy informed on it? A’ Us EDITORS TABLE. EDITORS: A. S. PACKARD AND E. D. COPE.

Although the number of papers read (175) was smaller than at some preceding meetings, the quality, in many of the sections at least, was exceedingly good. If it were possible we should pre- fer that the American Association might always meet beneath the shadow of a university, and in a town like Ann Arbor, whose raison d'etre consists of the university which it contains. But such towns are rare in the United States, and we cannot expect to be always surrounded by the favorable conditions of the meet- ing which has just closed its sessions. The controversy over the question whether the human embryo has a genuine tail like that of the embryo of other mam- mals, has been nearly set at rest by the painstaking researches of Professor Fol, of Geneva. We have translated his article from the reprint in the Journal de Micrographie for June, and the reader may for himself see how this skilled histologist has proved the presence for a short period in embryos in the fifth and” sixth week of their development, of four embryonic vertebre, which after the sixth week fuse together ; the tail itself at first elongated and regularly conical, becoming shorter and more rudimentary. Professor Fol, in closing, simply contents himself with remarking that the embryo human tail well deserves the name, and that the organ “evidently deprived of all physiological utility, should be classed in the number of repre- sentative organs.” This temporary, deciduous organ, which appears for only a brief period and still comparatively early in embryonic life, points unmistakably to the origin of man from some tailed mammal, ‘whether a monkey, or some less specialized form, possibly allied to that generalized type, the lemur. This instance is one of several others in the growth and struc- ture of the human body which affords so strong circumstantial evidence of man’s descent from some lower animal form, that it amounts, in minds trained to embryological, 22 eames and ana- tomical methods, to the strongest probability. = —— The death of that veteran French naturalist, Henri Milne- Edwards, who at the great age of eighty-five passed away July 29, in his house in Rue Cuvier near the Jardin des Plantes, is a notable event in the history of biological science. Milne-Edwards 974 Editors Table. [October, will be remembered as a physiologist for his discovery of the principle of the physiological division of labor, as well as his laborious and extensive work, in fourteen volumes, on compara- tive physiology and anatomy. But as a zoologist his fame was wid e was to France what Owen is in England and Agassiz was in America. His special anatomical memoirs were conspic- uous examples of the skill and nicety in injection and dissection which characterized the Cuvierian school, his treatises on the organs of circulation of Crustacea being of marked beauty and value. His general zoölogical works were the Histoire Naturelle des Crustacés, published with the aid of Audouin, and with Haime, an extended work on corals. Biologists, being human beings, have a spice of dogmatism and sectarianism in their nature, and in a notice of the great French naturalist in an Eng- lish scientific journal, it is stated that Milne-Edwards did not late in life change his views as to the origin of species. We never knew, however, of his publicly attacking champions of the new biology. In his son, Alphonse Milne-Edwards, the family name is not now less conspicuous than for the past fifty years as a lead- ing one in French biological science. The U. S. Coast Survey, which for so many years under the direction of Bache and others rendered such signal service to Science while pursuing its legitimate work, has been clouded by alleged official misconduct. Charity will be felt for any one who suffers official punishment after life-long services to science and the public welfare. Long before the present civil service reform in poli- tics, the Coast Survey was managed with singular ability and economy. Its work will go on as long as geological agencies produce changes, however minute, in our coast lines and harbor approaches, whether “a thousand years” or more. Our other scientific bureaus have certainly been conducted with far more ability and economy than some departments and bureaus filled by political appointments. Still, rigid economy and business tact will be demanded of our scientific directors and commissioners, as they have been in the past.

FORBES’ A NATURALIST’s WANDERINGS IN THE EASTERN ARCHI- PELAGO.'—Though inferior in general scientific interest and liter- ary execution to Wallace’s Malay Archipelago, Mr. Forbes has produced an excellent book of travels, which we have read with much interest. Most of the islands visited by Wallace were also visited by our author, but the routes of the two travelers were in each island different. The book, as the author modestly states, is a transcript of the more interesting of the field-notes made during his wanderings, and is to be “considered” in the light of an addendum to Wallace’s “ model book of travel.’ Besides his observations on the formation of the Cocos-keeling islands and numerous entomological and ornithological notes, the matter largely relates to the botany of these islands, as well as the manners and customs of the natives and mixed races with whom Mr. Forbes was in constant contact. No detailed account of the Timor-laut islands has appeared before that of Mr. Forbes, and little has been published on the inhabitants of the interior of Timor ; and, by the way, a residence in Timor, owing to the deadly fever of the coast and the continual warfare between the different villages, was not found to be particularly comfortable. Indeed, Considering coast fevers, insect pests, venomous animals, not to mention an occasional tiger, thieving natives, the liability of meet- ing Malays “running a muck,” the jealousy and selfishness of | Native officials, and tropical heats, rains, earthquakes and an oc- casional volcanic eruption or cyclone, a naturalist’s life in the East Indian archipelago has its lights and shades. 14 Naturalists Wanderings in the Eastern Archipelago.

[ October, Mr. Forbes’ notes and conclusions as to the origin of coral reefs are of interest, as the subject is now under fresh discussion, Visiting the Keeling atoll nearly fifty years after Darwin, he found that the encroachments of the sea on the land “ had not increased at all; on the contrary, it struck me that the land was gaining on the lagoon.” Between Direction island and Workhouse island he observed what seemed to him signs of recent elevation. His conclusions are in the following words: “I incline to believe, therefore, that the Keeling-reef foundation has arisen as Murray, Semper and Agassiz have suggested ; but that its islets have been the result of the combined action of storms and the slow eleva- tion of the volcanically-upheaved ocean floor on which the reef is built.” Among the notes on mammals is an explanation, new to us, of the use of the upturned and hooked teeth of the hog-deer (Babi- rusa). They are used, he was told by the natives, “to hold to the bottom of ponds by, when hard pressed by hunters.” The author’s journey by raft, or rakiting, down the Musi river to Palemberg was remarkably interesting, and the following ex- tract will convey an idea of our author’s powers of description when at his best, for at times his style is slovenly and ungainly: o recall the magnificent flora of the upper reaches of the river almost makes me retract the statement that the tropics pre- sent few flowers; for so blossom-spangled a road it would be difficult to match anywhere ;—it is only in the beginning of the wet season, however, and along the steep banks of some such river, wide enough to let in the sunlight and the free breath of heaven, that one must look for, or indeed expect to be able to see such a display. The singular trackless streets, roads and paths of water by which I rambled among the forest avenues are never-to-be-forgotten reminiscences; nor lower down the slow majesty of the widening river between its level banks fronted with tall reeds, dark-foliaged figs, and groves of Eriodendron trees, with their stiff trifid arms; and at last the broad expanse of its united affluents, by whose sources I had for so many months encamped, drawing towards itself the atoms of produce of two degrees of latitude, and concentrating them into a hot nucleus of commercial life and activity.

Descriptions by various specialists of the new forms dis- covered are added in fine print, with lists of plants, among them a new species of Brugmansia of the family Rafflesiacez.

On the other hand the maps are frequent and well engraved. THE REPORT OF THE FIFTY-FOURTH MEETING OF THE BRITISH ASSOCIATION.—One very tangible result of the last meeting of the British Association, held at Montreal in August and September, 1885, is a volume containing 980 closely-printed pages, besides more than 200 pages occupied by the table of contents, list of mem- bers, etc. More than forty reports upon the state of science, by various committees and individuals, and about 340 papers read in the various sections make a total too long for review, and the NATURALIST is therefore compelled to notice only a few of the papers read upon biological and geological subjects. Among these the report of Messrs. Etheridge, Woodward and T. R. Jones, upon the fossil Phyllopoda of the Palzozoic rocks (pp. 75-95), that of Messrs. Sorby and Vine upon the fossil Polyzoa (pp. 97-219), that upon the Zodlogical Station at Naples (pp. 25 3-263), that on the Archzan rocks of Great Britain, by Profes- : sor T. G. Bonney (pp. 529-551), and that upon the characteristics of the North American flora, by Professor Asa Gray (pp. 555-568) may be especially mentioned. A most thoughtful and pregnant article is the address of W. T. Blanford, president of the Geologi- cal Section. It deals with the startling exceptions to the rule that beds exhibiting “homotaxis,” or similarity of fossil forms, are in reality contemporaneous. By a comparison with each o of the faunas of the Pikermi beds, of the Siwaliks, Gondwana and other fossiliferous strata of Hindostan, and of the Australian coal measures and associated beds, he proves that homotaxis or the want of it is not sufficient to prove the synchronism or lack of synchronism of beds situated in different parts of the world. No less than forty-eight papers were read in the Geological sec- tion, and are represented here by abstracts of moderate length. The address of Professor H. N. Mosely, president of the Bio- logical section, deals with the phenomena of pelagic and deep-sea life, the amount of oxygen, nature and quantity of food, zones of 978 Recent Literature. [ October, depth, derivation of the abyssal fauna and other questions which the investigations carried on by the various deep-sea exploring expeditions have brought to the front. Among the remaining fifty-eight biological papers read, it will suffice to mention those of C. Spence Bate on the geographical distribution of the macru- rous Crustacea, of P. H. Carpenter upon the geographical and bathymetrical distribution of the Crinoidea, and that of E. A. Schafer on the mechanism of absorption. Many of the papers which are here given in condensed form have also been published at full length in scientific periodicals, Vinine’s “ An InGLorious Cotumsus.”'—This volume of more than 700 pages is devoted to the task of proving that Hwui Shan and four other mendicant Buddhist monks, who in 458 A. D came from Afghanistan to China, and thence proceeded further to the east, really discovered America. The points brought out in favor of this idea are certainly very many and their cumulative force large. Hwui Shan returned to China in the first year of the Ts’i dyn- asty, and told many med stories concerning the countries of “ Marked Bodies,” “Great Han eh “Fu-sang”’ which he had seen on his journeyings, as eel about a “ country of inhabited by females with Ba podis and long locks, who carry their young on their backs and nurse them a hundre days.

Many preceding authorities have noticed or translated Hwui Shan’s recital, and Mr. Vining mercilessly quotes them all in the first portion of his work. This is very fair, but makes extremely wearisome reading.

Arrica.—African News—The Revs. G. Grenfell and T. J. Comber have contributed to the Proc. Royal Geog. Society an account of their explorations on the Congo. The Bochini or . Kwa river was ascended for about 100 miles, and was proved, notwithstanding its apparent smallness, to receive the great river. Qwango and also the Njali Pi, or Black river, coming from Lake Leopold II. Between Stanley Pool and the mouth of the Boch- ini the south bank of the Congo seems almost uninhabited. The journey from Leopoldville to Bolobo was accomplished in four days, traveling ten hours a day. The mouth of the Bochini is in lat. 3° 12’, and is almost closed up by rocks, which obstruct the n first thirty miles of the channel. The Ba-buma of this river are = regarded by our travelers as the best examples ot the African = they have met with. They are well-formed, intelligent, friendly, industrious, and seem to lead a happy domestic life. Their chief isa woman, Nga-Nkabe. Tall and stalwart, with a dignified air and queenly pose, Nga-Nkabe evidently knows how to rule. 'he Qwango comes in from S.S.E. with a depth of two fathoms, . width of 400 or 500 yards and a current of a mile and a half an ur.

Women wear a solid brass collar weighing twenty-five to thirty pounds. Our travelers arrived at Bolobo - during the saturnalia consequent upon a chief’s death, and state their impression that the main characteristics of the people are drunkenness, immorality and cruelty in the most revolting excess. Mr. H. E. O’Neill draws attention (Proc. Roy. Geog. Soc., 1885, p. 373) to the neglected port of Nakala, in Fernao Veloso bay, north of Mozambique. It has numerous good anchorages, and offers magnificent conditions for the founding of a colony. Nakala is a deep inlet forming a southern prolongation of Fernao Veloso bay. Dr. H. Zoller, in his account of Togo land, pub- lished in the Kolnische Zeitung, states that the streets of the Togo villages are better swept than those of Berlin. Refuse is thrown into large holes, which are covered over when full. The rectan- gular houses are built of huge bricks made of clay, reeds and straw, the: roof is thatched with straw, and the floor is covered » with red clay. Sometimes there are two or more apartments, provided with windows having wooden shutters, and occasionally there is an upper floor with a kind of staircase. he expedi- tion of Messrs. F. L. and W. D. James has returned to England. The Messrs. James intended to cross from Berbera to Magadoxo, but though accompanied by sixty Somali and with Dualla, one of Stanley’s best men, for headman, they only succeeded in reaching Barri, on the Webbe river. The greater part of this journey of about 400 miles, was over territory before unvisited by Euro- peans. Barri is 215 miles from Magadoxo. Since the depar- ture of Mr, Comber, his colleague, the Rev. G. Grenfell, has as- cended the Mabangi, or Ubangi tributary to 4° 30’ N. lat., the _ Alkere to 2° 50’ N., the Lubilash, or Lomame, to 1° 50’ N., the bura to cataracts ten miles from its mouth and the Kelemba, or Ruki, as far as it was navigable, viz., 100 miles. The Sankuru Proved an unimportant small stream ; the Albangi is he river, but the tribes are bad and fierce; and the Ukere is thought to be the Welle (Proc. Roy. Zodl. Soc., June).——Mr. E. H. pom an American missionary, has journeyed from Inhambane to Limpopo, through a region which is at present a blank on our maps. The Bombom river forms the western boundary of the Portuguese province, and drains a large area of Western Inham- e, as well as the eastern slope of the Makwakwa ridge to the west. The country west of this ridge is semi-deserted in conse- quence of the raids of Umzila’s soldiers. From the Makwakwa ridge to the Limpopo is level land. The Ama-gwaza, or people of Umzila, inhabit or control the country from the Zambesi to the Limpopo, and with the exception of the Portuguese pos- Sessions of Chiluan and Inhambane, from the sea in the east to the Matabele country on the west.

Prejevalsky has discovered three peaks, each over 20,000 feet high, in the middle range of the Kuen-lun. The plateau skirting the middle Kuen-lun has an average height of 4000 feet. Dr. Gottsche, who has recently returned to Europe after a journey of over 2000 miles in Korea, believes that the population is much underrated. He has visited all the eight provinces and eighty-four out of the 350 districts, and has, through influential support which he received, been enabled to collect much statistical information which is wholly new. He states that the official census only takes into account the adults, and that therefore its nine millions must be increased to over twelve. The geology of Korea seems to be that of the bordering Manchuria. He found few traces of that early devel- opment of art and science which made Korea the instructress of Japan. The labors of Dr. A. Griinwedel and Dr. R. Virchow with Bengalese and other intruders, and have a yellow complex- ion. Dr. Virchow is careful to point out that none of these hill tribes lend any support to the theory of an aboriginal Negrito population formerly spread over the whole of India and Indo- China. —— Iturup and Kunashiri, the most southern of the Kuriles, are also the largest. Iturup, according to a recent num- — ber of the Japan Gazette, is 113 miles long and seventy-seven 1n greatest width; Kunashiri is sixty-two miles by seventeen. All the Kuriles are very desolate, and only sparsely occupied in sum- mer by Japanese and Ainos, who come to fish. In Iturup there is an impassable jungle of bamboo grass between the coast and the mountains. Professor Milne thinks it not unlikely that the -Iturup bear, which seems to resemble the grizzly, may be new to - science.

Gardiner, Jr., in a communication to Science, describes a natural bridge sixty-five feet long, fifteen feet wide where narrow- est and two feet thick in the center, situated in a small cañon at a distance of about twenty miles from the Atlantic and Pacific railroad, near the boundary of Arizona and New Mexico. Lieut. Hohm, of the Danish Greenland exploring expedition, separated from Dr. Eberlin at Tingmiarmint (62° 40' N. lat.) with the intention of reaching Angmaksalik, in 65° N. lat., where there is a fixed settlement not hitherto visited by Europeans. The heathen East Greenlanders are as tall as the peoples of North Europe, and mostly have dark eyes and hair. They seem to have nothing in common with the Eskimo, yet their utter absence of Norse tradition and total want of civilization, is thought to preclude the possibility that they are descendants of the Norse- men. GEOLOGY AND PALÆONTOLOGY. Tue RELATIONS OF THE PUERCO AND LARAMIE DEPOSITS.— Some writers having suspected the identity of the formations above named, and the consequence which follows, that the Puerco mammalian fauna was contemporary with the dinosaurian fauna of the Laramie age, the following observations on their strati- graphic relations are now given. They are derived from the notes of several years’ residence and exploration by my correspondent, David Baldwin, which connect those made by myself in New Mexico in 1874, published in the Wheeler Survey Report, with those made by Holmes and Endlich in 1878 in Colorado, and published in the Hayden Survey Report. At the locality where best developed, the Puerco beds have a thickness of about 850 feet, and contain Mammalia to the base (see Naturauist for April and May, 1885). The Laramie beds succeed downwards, conformably it is thought by Mr. Baldwin ; and have a thickness of 2000 feet at Animas City, New Mexico. They rest on Fox Hills marine Cretaceous of less thickness. A few fossils sent from time to time by Mr. Baldwin identify the Laramie. This is especially done by the teeth of the dinosaurian genus Dysganus Cope,! which is restricted to the Laramie * Proceedings Academy Philada., Oct., 1876. 986 ‘General Notes, [October, formation everywhere. Also by the presence of the genera Læ- laps and Diclonius, which in like manner do not extend upwards into the Puerco beds. The Lælaps is principally represented by teeth, which resemble those of the Z. izcrassatus Cope more than those of any other species, although these parts are not alone sufficient for the determination of species in this genus. The Dysganus agrees with the D. encaustus Cope, which, with the Zæ- laps incrassatus, was described from specimens from the Upper Missouri. A species of Trionyx and a large crocodile accom- pany these species. The latter differs in the character of its teeth from any species known to me. The crown is compressed at the apex, and there are two well-marked cutting edges, which slope in such a way as to divide equal faces unsymmetrically, 2. e., the greatest convexity of one not being opposite to that of the other ; the transverse section resulting being an oblique oval, or at the base a regular oval, with cutting edges at points diagonal to each other. On one side of the tooth thus divided, the surface is grooved by twenty-five strong sulci, which become very fine at the obtuse apex of the tooth. The opposite (external ?) side of the crown is smooth, excepting traces of sulci and silky grooving towards and at the apex. Diameter of crown where broken off, It is thus evident that the Puerco formation is quite distinct from the Laramie, although it is possible that it may be proper to associate it with the Laramie in the Postcretaceous series.! When the Cretaceous mammalian fauna comes to be known, it will be very apt to agree with the Puerco in its leading features. These are, the absence of Perissodactyla and of Rodentia, and of course of mammalian orders not found below the Miocenes ; and in the constitution of the mammalian fauna by Condylarthra, Bunothe- ria and Marsupialia exclusively. The Postcretaceous series as & whole may be ultimately distinguished from the tertiary by these peculiarities, together with the presence of the reptilian genus Champsosaurus.—Z£. D. Cope. This has been done in the table of formations in Vol. 111 U. S. Geol. Survey, F. ayden, Tertiary Vertebrata, p. 42. | 1885.] Geology and Paleontology. 987 water increases the tendency to fusion, it is probable that this plas- tic zone commences at a depth of about forty miles. The interior of the earth may have a rigidity exceeding that of steel, but even if, according to the ideas of Wadsworth and some others, the in- terior is liquid, this does not affect the action of the surface zone nents, while the ultimate crushing produced the mountains. Mr. Crosby does not, therefore, believe in the permanency of continents, which is held by many geologists as an article of faith. We have, he argues, certain knowledge of a Paleozoic subsidence of 40,000 feet in the Alleghanies, a Mesozoic subsidence of 50,- 000 feet in Central Europe, and, according to King, a subsidence of 60,000 feet in the Rocky mountains. With these facts in mind how can it be held that any part of the floor of the deep sea ever has been or will be elevated to form dry land? GEOLOGICAL News.—General—All the geological formations occurs everywhere on the edges of the older mountain ranges. Basalt is rare, the volcanic rocks are mostly trachyte and ande- site, and granite covers an area only second to that occupied by e Paleozoic formations. Volcanic tuff, consisting principally of decomposed silicates, is among the soils of Japan, and forms _ Most of the uncultivated plains at the foot of the mountains. The geological and topographical survey of Japan has worked over an area of about eighty geographical miles square. Paleozoic—Mr. O. A. Derby states (Geog. Physica do Brazil, Vol. 1) that the Brazilian tablelands are composed of horizontal or nearly horizontal beds. The basis of the plateau consists of ancient metamorphic rocks; these form nearly the whole of the mountain and mountainous tablelands, and appear whenever later tocks have been denuded. They thus occur at the bottom of nearly all river valleys. The older of these rocks are highly Crystalline, the newer less crystalline. The granites, syenite, 988 General Notes. [October, gneiss, etc., of the first series is supposed to be Laurentian, while the quartzite schists and limestones, etc., of the second series are Huronian. The latter series is the great mineral repository of Brazil. Here occurs the schistose micaceous quartzite called iron and extensive beds of hematite and other iron ores, and gold. Tapanhoacanga, consisting of masses of iron ore cemented by limonite, is often very rich in gold. The Serra do Espinhaço is capped with sandstone believed to be Silurian, and probably a part of the sandstones of the Sao Francisco-Tocantins divide are also Silurian. The tablelands of the Parana basin, composed of sandstone and shale with some limestone, are probably Devonian and Carboniferous. Devonian fossils characterize an extensive area in the Campos Geraes de Parana, while the Carboniferous covers a large region farther to the westward in the same province, and in Sta Catherina, Rio Grande do Sul and Southern and West- ern Sao Paulo. Coal has been found at various points. Immense dykes of diorite traverse these two formations, and by their de- composition afford a dark red soil called zerra rova—O. A. Derby (Am. Four. of Science, Sept., 1884) shows that the flexi- bility of itacolumite is only a surface quality. In a cutting upon the Rio and Minas railroad (Brazi!) a thickness of forty meters of itacolumite is laid bare. The upper portion consists of massive beds from one to three meters thick, in which flexible portions are rarely found. In the lower part the beds readily divide into thin laminz, most of which are more or less flexible. Exposures of unweathered itacolumite are rare, and from the study of this Mr. Derby concludes that flexibility is not an original character- istic of the rock but a phase of weathering brought about by per- colating waters. Stlurian.—Sr. Leon Tourquist has published descriptions of 113 species and varieties of trilobites discovered in the Silurian basin of Siljan, in Dalecarlia. The descriptions mainly rest on detached heads and pygidia, as the fossils are fragmentary. Carboniferous.—S. H. Scudder has described two new Carbon- iferous insects from England. One of these can with certainty be referred to Brongniart’s group of Protophasmida. The wing is broadest in the middle, and from the appearance of the frag- ment, which is 75™™ long, must have had a length of 130 ™ So | that the living insect probably possessed an expanse of wing of at least ten inches. =~ _ Cambrian.—Mr. W. O. Crosby (Proc. Bos. Soc. Nat. Hist.) de- _ fends his previous conclusions respecting the relations of the _ conglomerate and slate in the Boston basin. He maintains that _ the conglomerate underlies the slate, that there is essentially but one formation of conglomerate and one of slate; that both are nordial, or at least Cambrian, and that the Boston basin con- * 1835.| Geology and Paleontology. 989 tains no Carboniferous beds. He declares that the Carboniferous shales and sandstones are quite distinct lithologically from the slates of the Boston basin, which latter, as well as the conglom- erate, are traversed in all directions by numerous and large dykes of trap or diabase, while no eruptive rocks have ever been dis- covered in the adjacent Carboniferous. The rocks are decidedly omogeneous, passing gradually into each other, and have also a general agreement in strike and dip. The conglomerate under- lies the slate, not because it is older than the slate, but because it was deposited in shallow water, the slate in deeper, and the latter deposit commenced before the first.was completed. In not a few instances the conglomerate can be seen to pass beneath the slate, Cretaceous—M. Ch. Arnat (Rev. Scientifique) describes the geological structure of the Saharan district of M? zab. is prin- cipally consists of an elevated plateau (hamada) of Cretaceous rocks, rising toward the north-east into a cliff facing the basin of the Oued Loua, while toward the south-east it is lost beneath the alluvium of the Oued Rhir. Thus this rocky plateau, which is entirely desolate and without running water, is bounded east and west by alluvial deposits. Calcareous concretions mark the pas- and Malmo. Those of Kristianstad are chiefly gruskalk (a lime- Stone composed of the fine débris of shells of mollusks and €chinoderms) with a mixture of quartz sand-grains and occasion- ally metamorphic boulders. In Ystad the prevailing rocks of the Cretaceous strata are incoherent calcareous sandstones, with a variable quantity of green grains; while in Malmo the beds are Pure white chalk of various degrees of hardness, with abundant layers and nodules of flint. These Malmo beds are an easterly Continuation of those of Denmark, and closely resemble those of 990 General Notes. [ October, Norwich (Eng.). In Malmo the upper chalk is overlaid by the Danien, or newer chalk, which is without belemnites or Belemni- tella. From the upper chalk the only new species described is a Lingula, but from other horizons there are sixteen new forms, The most prolific brachiopod fauna is the lower division of the Kristianstad district, characterized by 5 Sasa ventricosus. _ Tertiary —Ernst Hoken has endeavored to ascertain the groups, of fishes to which belong the otoliths, which are the most com- mon remains of bony fishes in the Oligocene of North Germany. He finds the Gadidz predominate, but identifies also species of Percide, Sciænidæ, Sparide,. Triglide and Pleuronectide. Although Professor Marsh’s book on the Dinocerata bears date 1884, the first copy was eresi from the binders rede the end of February, 1885. ardner, in a lecture upon the Age of the Basalts of the North. east Atlantic, tte that the determination of the Antrim basalts as Miocene is not satisfac- tory; and that the assumption that all floras comprising modern and temperate-looking genera (such as willow, beech, alder, hazel, poplar, elm, pine, liquidambar) must be Miocene, while a flora of palms, Proteacez, figs, Aralias, etc; must be Eocene, is erroneous. The whole of the American flora with Dicotyledons would have been absorbed into the Miocene had it not been for stratigraphical evidence. The so-called Miocene plants of Greenland are, by Mr. Gardner, referred to the middle Eocene, and the unfossiliferous beds below their horizon to the base of the Eocene. The basalts in Ireland restore the upper chalk. In conclusion Mr. Gardner said—“ I think we may assume that the old land on which this flora (that of the middle series of the Irish basalts) grew formed a part of the continent of Europasia, in Eocene times, and further that it formed or was not ‘distant from its western coast line.” Mr. rdner believes that the silicified wood and lignites of Lough One ae may be derived from the basalts. The prevailing conifers ese Eocene basalts are a cypress, a cryptomeria and a pine. — Post-Glacial—W. O. Crosby (Proc. Bost. Soc. Nat. Hist.) gives what seems a very probable explanation of the gorge called Purgatory, at Sutton, Mass. The chasm is about 50 feet wide, with vertical walls, and pierces the micaceous gneiss of the e region. He suggests that during some disturbance of the earth’s = Crust, the wedge-shaped mass of rock between two master joints ~. has dropped. This idea is in accord with facts. The chasm is at parallel to a well-defined system of joints, and its walls are _ evidently joint-places. There are no evidences of marine erosion . to support Dr. Hitchcock’s theory. The date of this chasm must be post-glacial, as, if it lay in the path of the ice-sheet, it would lave been filled with glacial detritus. The explanation will of ourse apply to some other similar gorges. wy.—Prof. A. Nehring (Sitz. Ges. naturf.

At that time middle Europe was a land of steppes, and a strong-kneed, thick headed, medium-sized wild horse existed there. Later on the steppe became covered with forest, the moist climate of which was unfavorable to the horse, which be- came confined to the pasture grounds and thus fell more and more under the influence of domestication, whilst it degenerated into the small weak-kneed horse found in the moors of Northern Germany, in some pile-dwellings, and in the “ Kreisgruben ” of Oldenburg. The descendants of this European horse can still be traced in some breeds. This view does not shut out the idea that - the introduction of the Asiatic horse may have contributed to the change of type. Recent—Dr. R. v. Lendenfeld has found undoubted traces of glaciation throughout an area of 100 sq. miles upon the highest part of the Australian Alps, at elevations of above 5800 feet. The rocks showing traces of ice-action are all granite. MINERALOGY AND PETROGRAPHY:.! Tescunite.—Dr. Carl Rohrbach? has made a thorough reéx- amination of all the occurrences of teschnite of which he could obtain specimens, and concludes that this rock is not entitled to the position to which it was assigned by Rosenbusch in his sys- tem of rock classification published in 1877. The paper opens with a valuable review of the literature of this much discussed rock-type. The best known localities are those in the neighborhood of Teschen, in Moravia, where the rock, as early as 1821, was described as a diorite. This determination appears to have been regarded as satisfactory until Hohenegger „threw doubt on it, and in 1861 proposed to call this in many respects peculiar group of rocks “teschnite.” This name was accepted by Tschermak, in 1866, for the lighter colored varieties, while he designated the darker ones as picrite. Zirkel, in 1868, and Tschermak, in 1869, first mentioned nepheline as a constitu- €nt of these rocks. In 1877 Rosenbusch published the results of his examination of these rocks, which he defined as pre-Tertiary Plagioclase-nepheline aggregates, and as such assigned them a _ very important place in his classification. Other masses of a similar age and mineralogical composition have been described by Tschermak from the Caucasus, and by McPherson in Portugal. Analcite, supposed to be an alteration of the nepheline, is a com- mon constituent at all of these localities. : __As the principal primary constituents Dr. Rohrbach designates plagioclase, augite, hornblende, biotite, olivine, magnetite an apatite.

[ October, in well defined crystals, and “ xenomorphous” when it merely fills the spaces left between the plagioclase crystals, as is common in rocks of the diabase type. A compact brown hornblende is a common constituent and presents the most interesting relations to the augite. These are described at length and admirably illus- trated in a colored plate. This hornblende which very frequently makes up the outer portion of a pyroxene crystal, is regarded as in no way of secondary origin, but as an original crystallization due either to changes in chemical composition or physical condi- tions in the magma. The following analyses of the two minerals illustrate instructive chemical differences: - Augite.

The nepheline Dr. Rohrbach was unable to discover in any -specimens of teschnite from either Moravia, Caucasus or Portu- gal. He thinks that what has thus far been considered to belong to this species is in reality apatite, and would hence strike tesch- nite from its place in Rosenbusch’s system. [Even in case Dr. Rohrbach’s results regarding the presence of nepheline in the specimens examined by him are entirely correct, no account has been taken ọf the dykes of ancient plagio- - clase rocks occurring in the Silurian limestone near Montreal, in Canada, which, according.to Drs. Hawes and Harrington, are un- doubtedly rich in nepheline. This mineral is often present in large sharply-defined hexagonal crystals closely resembling those so characteristic of the Katzenbuckel “ nephelinite.” —G. H- W.]. METAMORPHOSIS OF GABBRO.—The widespread origin of horn- blendic schists by the uralitic alteration of massive pyroxene rocks receives additional evidence in its favor wherever the atten- tion of geologists is especially directed to it. The observations of Lehmann in Saxony, Reusch in Norway, Phillips in Bagreg Becke.in Austria, Streng and Irving in the region about Superior in the U. S., all indicate the great geological eri of molecular changes i in prodocing amphibole schists from pyrox- ~ ene eruptive rocks, The studies of Kloos'in the Black Forest point to a like relation between the gabbros and diorites of Ehrs- berg. Mr. Frederick H. Hatch, of London, has contributed a similar investigation of the gabbro occurring at ’Wildschénan in the : “coast eri 11, Beil. Bd. 1885. | Mineralogy and Petrography. 993 Tyrol, and of the associated hornblende schists, which he regards as having undoubtedly been derived by its uralitization! Severa wood-cuts illustrate the different stages of the alteration as it was observed under the microscope, The writer finds that the schis- tose structure is developed in the rock in proportion as the alter- ation of the pyroxene to hornblende has progressed, and is hence inclined to attribute both to the action of great pressure. Two parallel series of alteration which have gone on in the gabbros of Wildschönau, the writer illustrates in the following manner : ; Normal-gabbro arm aes Beemer oE.

Van Werveke* publishes the results of a new microscopical study of a large amount of petrographical material in which this class of minerals plays an important rôle. This consists of the ottrelite schists occurring near Ottré and Viel- Salm in the Ardennes. These he divides into ottrelite-phyllite proper, garnetiferous ottrelite-phyllite, magnetiferous ottrelite- phyllite and ottrelite-bearing quartz-breccia. Professor E. Cohen, formerly of Strassburg, who has recently been called to the University of Greifswald, has a Jetter in the Neues Jahrbuch fiir Mineralogie,’ in which he revises the determination of the diallage in the Schriesheim picrite, made by him some twelve years ago. The resemblance of this rock to certain olivine rocks occurring near Peekskill, on the Hudson river, is very striking. In them large bronze-like cleavage surfaces of hornblende are mottled with much smaller grains of olivine and pyroxene. An almost identical mineral occurs in the Schreisheim rock, which was formerly considered by Cohen as diallage, but which now, Ueber den Gabbro aus der Wildschönau in Tirol und die aus ihm hervorgehen-. oe Gesteine, Tschermak’s Min. und Petrog.

The writer proposes to call this type of rock, composed essentially of olivine and hornblende, “hudsonite,” on account of its being so well developed at Stony point, on the Hudson river. [The name “hudsonite” was applied, as early as 1842, by Beck to a variety of augite occurring near Cornwall, on the Hudson river. It would therefore seem preferable, if a new name is considered necessary, to employ some other than that proposed by Cohen. The present writer has elsewhere suggested “ cortlandtite” as appropriate, since this rock is such a typical member of Professor Dana’s “ Cortlandt Series.” —G. H. W.|——-Dr. K. Oebbeke,’ of Munich, communicates some observations made by him on a specimen of andesite from the summit of Mt. Tacoma, Washing- ton Territory. The question of the existence of pleochroic augite is again discussed and regarded as undecided in spite of the work of Cross, Hague and Iddings on the western hyper- sthene-andesites. If the matter is still in doubt it must be con- fessed that Oebbeke here furnishes but little convincing evidence in favor of a pleochroic monoclinic pyroxene. M. Ver- beek’ makes some interesting remarks on the recent ‘lavas re the East Indian archipelago. These are, for the most part, hyper- sthene-andesites, or, as this writer prefers to call them on account of the ‘presence of both hypersthene and augite, “ pyroxene- andesites.” The hypersthene is almost always in excess of the augite. Pure augite andesites have not been observed, but such as contain only hypersthene rarely occur. The complementary roles played by the hypersthene and olivine in these rocks was noticed _ by Verbeek independently of Hague and Iddings, who discovered and described the same in their notes on the hypersthene ande- site and basalt of the Western U. S. in 1883, Mr. G. P. Mer- rill? of the U. S. National Museum, has published some notes on the hornblende andesite from the new volcano on Bogosloff island, in Behring sea. They are quite normal in appearance, containing lath-shaped plagioclase crystals, brown hornblende and reen augite imbedded ina microlitic base.

Below we give brief abstracts, which will show the general nature of the papers. “An observation on the hybridization and cross-breeding of plants,” by E. Lewis Sturtevant. This gave in detail the obser- vations on crossed beans, maize, barley, peppers, tomatoes, lettuce and peas, made at the New York Agricultural Experiment Sta- tion. Asa result of.the observations the author concludes that in our domesticated vegetable plants cross-fertilization shows its effects at once in the reproduction of the form-species and varie- ties which are involved in the parentage of the crossed seed, or, in other words, the effect is atavism rather than a blending of properties. “ Germination studies,” by the same author, gave the results of making numerous duplicate germinations, showing that different percentage-results are obtained as the quantity of seeds used is © large or small. The influence of various temperatures was also discussed. These two papers will appear in the NATURALIST. “ The question of bisexuality in the pond-scums,” by Charles E. Bessey. It has been held by some botanists that the pond- scums (Zygnemacez) show a distinct bisexuality, one of the fila- ments being male, the other female. Certain facts were presented which render such a view untenable. In many plants the cells of the same filament fertilize one another, as is notably the case in the forms which have been described as Rhynchonema. Several cases of hybridization were cited in which two filaments, both of which bore resting-spores, united with one another and produced a hybrid spore. The conclusion was that the pond-scums are not bisexual, but rather unisexual, that is, that while sexuality un- doubtedly exists, there is as yet no differentiation into the proper male and female. Accordingly these plants must take a position just above the asexual prototypes, but below the clearly bisexual oophytes. : “The process of fertilization in Campanula americana,” by Charles R. Barnes. This species is strongly proterandrous. The pollen is scraped out of the anthers by the hairy style and brushed off before the stigmas open, thus securing cross-fertilization. The development of the pollen is normal. The stigmas are held to- gether till mature by interlocking papilla. The hairs on the style become partially introverted, thus freeing the pollen. The pollen spore contains two nuclei, the larger of which, the vegetative, becomes disorganized shortly after entering the pollen tube, while the smaller spindle-shaped generative nucleus persists. The embryo-sac is cylindrical, with a gradual enlargement near - the micropylar end, where is located the egg-apparatus, and an abrupt enlargement at the chalazal end, in which lie the antipodal cells. There are usually two sac-nuclei. VOL, xIX.—no. x, 65 996 General Notes.

The paper was followed by an account of the methods used, and illustrated by figures drawn upon a large chart. “Proof that Bacteria are the direct cause of the disease in corn-meal juice. After a few days some of the bacteria, which had increased rapidly in this medium, were transferred (a drop only) to another sterilized preparation of corn-meal juice.

J. Burrill. There are two kinds of mechanical injury due to a low tempera- ture, viz: (1) The cracking and splitting of the bark and wood in a longitudinal-radial direction ; and (2) the separation of the con- centric layers of wood and bark, and especially the rupture of the cambium, thus destroying the bark and perhaps also killing the tree. The first injury is due to the shrinking of the tissues by cold. The second is due to the growth of ice-crystals in the annual rings or on the surface of the woo “Further observations on the adventitious inflorescence of Cus- cuta glomerata,” by Charles E. Bessey. A further examination shows that it is the universal rule in this species for the inflores- cence to develop from lateral adventitious buds, -and that no nor- mal inflorescence is developed. The adventitious inflorescence always bears a definite relation to the parasitic roots; that por- tion of the stem which bears roots produces adventitious inflores- cence, and the greater the number of roots the greater the mass of inflorescence.

Coulter. An ex- amination of many species of dicotyledons (belonging to the. orders Ranunculacee, Leguminosz, Rosacez, Saxifragacez, Onagracez, Rubiacez, Umbellifere, Composite, Borraginacee, - Scrophulariacez and Labiatæ) shows that in every case the first character recognized in the development of the flower is that of inferior or superior ovary, and that a most simple grouping of the orders upon that basis is possible. Grouping the dicotyle- dons upon this basis results somewhat as follows: The ompos- itæ take place at the head of the list, then near them come the Umbelliferze, Rubiacez, etc., etc. The intermediate orders which have inferior and superior ovaries, as the Rosaceæ and Saxifra- gaceze, would occupy a proper intermediate, position, and finally those with superior ovary or ovaries only, as the Scrophulariace, Labiate, Leguminose, etc., would be arrayed in a descending series. “ The development of the prothallium in ferns,” by Douglass H. Campbell. The paper gave the details of many observations upon the development of the prothallia of ferns, accompanied by figures of the various stages. “ Notes upon some injurious Fungi of California,” by William G. Farlow. The author observed Peronospora hyoscyami D.By. _ growing abundantly upon Nicotiana glauca, a shrubby plant, native of Buenos Ayres, which is now common in Northern Mexico and Southern California. As the shrub is a near relative of the cultivated tobacco, Nicotiana tabacum, there is danger that the parasite may be transferred from the { »rmer to the latter. The hollyhocks of California are affec.ed by a rust (Puccinia of some species) which was at first supposed to be identical with the hollyhock disease of Europe (Puccin a matvacearum). It is, how- ever, entirely distinct, being the sam e species as that which occurs upon species of Malvastrum in some of the Western States. There is danger that this may become transferred to the cotton lant. “A new chromogenous Bacillus,” by D. E. Salmon and Thomas Smith.

ENTOMOLOGY. Dr. BRAUER’s VIEWS ON THE CLASSIFICATION OF INSECTS.—In a work entitled “ Systematisch-zoologische Studien,” extracted from the ninety-first volume of the Proceedings of the Academy of Sciences at Vienna, Prof. Brauer, after a long introduction on evo- ution, makes many valuable and suggestive remarks on the fol- lowing subjects: The insect orders now existing did not originate om one another but from ancestors closely allied to one another ; affinities of Eugereon; the forms of insects the earliest and last to appear in different formations; hypothetical ancestral forms ; no Primitive forms connecting the existing orders of insects yet found; hecessity of the dismemberment of some existing orders which insects into originally wingless, and secondarily winged or wing- less forms ; relations of the mouth-parts in larve and imagines or 1000 General Notes. [October, their different changes of form; necessity of the increase in the number of orders based on the structure of the mouth-parts; relations of the parts of the thorax; relation of the thorax to the hind-body (1.

Ancestral forms, retrograde developments); genealogy; deceptive similar adaptive forms of different orders give the delusive appearance of a common de- scent or of a union in a single order; basis of the establishment of a peculiar (eigenen) order; the nymph as the stopping place (anhaltspunkt) for genealogical researches; the larva and geneal- ogy ; homologies of the nymph stages; relation and similarities between the ametabolic and metabolic insects ; registered or artifi- cial orders ; how valuable the secondary or primitive larval forms may be to the systematist ; orthognath and hypognath larva and imago ; -what points are to be considered in the use of the larve in classification; systematic characters of the same; characters taken from the structure of the nervous system; relations of the young form to the grown-up animal within the limits of a single order which are important for the determination of the grades of development; Packard’s superorders; posi- tion of the sixteen series of forms not connected by interme- diate links; relation of the allied series in different direc- tions ; view of the groups considered as orders ; supposed greater allied groups ; and, finally, the characteristics of the subclasses and orders of insects. Professor Brauer claims that exact researches on the existing insécts lead to the establishment of sixteen groups, or orders, which are not connected by intermediate types. “The path to a common ancestral form is interrupted in many places. More-. over, fossil remains do not fill up the gaps.” The fossils yet dis- covered show, he adds, that our so-called orders of insects have a high antiquity, for we find in the Paleozoic strata typical repre- sentatives, and indeed highly developed forms; he adds, emphat- ically, that there are no connecting types between the orders now in existence. He regards Dohrn’s Eugereon as a synthetic type, but not Scudder’s Atocina, Homothetidz, Xenoneuridz, Palzop- terina, Hemeristina, or Goldenberg’s Palzodictyoptera, which he considers as belonging to existing orders, remarking that “the collection of oldest known insects consists of genuine Orthoptera Sei Phasmide, Mantide); of amphibiotic Orthoptera Odonata and indeed, perhaps, Gomphidz, which were related to Stenophlebia, in the Devonian), genuine Neuroptera (Sialide in - the onian), and Rhynchota (Fulgoridæ), which differ only generically from the forms now living; or even, taking into _ account the more general generic characters, belonging to forms Brauer, after further suggestive remarks on the relations of the t insects to the existing orders, maintains that there are too 1885. ] Entomology. 1001 1.

[ October, given us a résumé of his memoir. He first studied the tissues of the larva and of the imago, and then followed out the mode of destruction of the larval tissues and the mode of genesis of those of the perfect insect. In his researches upon the nervous system of insects he found that besides the ganglionic chain and the stomato-gastric system, certain insects possessed nervous ganglia under the integuments, in some cases distributed without appa- rent order, but in others grouped symmetrically and connected with the principal centers. Another discovery was, that the sen- cells. Thus every part of the tegument has general sensibility. It has long been recognized that some of the hairs, or hollow conical outgrowths of the chitinous cuticle secreted by the hypo- erm, were special organs of touch, and were accompanied by a nerve which formed a ganglionic bipolar enlargement. M. Vial- lanes has proved that the hair is secreted by a specially modified hypodermic cell, and that in the protoplasm of this cell the ter- minal prolongation of the bipolar nervous cell ends. The dorsal vessel of an insect is formed of a single layer of cells, but each cell is contractile through the presence in it of striated muscular microscopic fibrils. Each of these fibrils begins and ends in a small disc. A theory, generally admitted, holds that the active unity of a muscular fibril must be the space between two small discs, but this is the first verification of the theory. __ The voluntary muscles of vertebrates exhibit little variety even in different zodlogical groups, and in any species have the same structure throughout. But in insects the motor muscles of the wings differ from those of the legs, and the contractile tissue of ‘the larva from that of the adult. In the muscles of the wings of a fly the fibers (faisceaux) have no sarcolemma and only a few fibrils (colonnettes) ; in those of the wing of Dytiscus the fibers. have no sarcolemma and only a single colonette or fibril, while in those of the legs the single fiber is enveloped in a sarcolemma. _ The ultimate elements, however, are the same in all. Previous . Ahistologists had proved that the motor nerves of the muscles of the legs of insects separate into their constituent fibrils imme- diately after penetrating the sarcolemma, but M. Viallanes shows that in insect muscles consisting of several fibers the nerve __ branches like a tree, as it does in vertebrates, while it separates at = es into its constituent fibrils in muscles formed of but one The second part of the memoir of M. Viallanes treats of the ruction of the larval tissues. M. Weismann had proved that muscles, tracheze, adipose bodies and peripheric nerves of the ‘entirely during the metamorphosis. M.

The anterior Each muscular fiber or bundle of fibrils is derived from numer- ous embryonic cells plunged in a homogeneous intercellular sub- Stance. The cells become the muscular nuclei, while the inter- cellular tissue becomes fibrillose and contractile. The work ends in a detailed account of the development of the eyes. The eye of an insect consists of three regions : ; compound external facetted eye; (2) the ganglionic disc which forms a sort of screen between brain and eye; and (3) the optic ganglion which is the most external enlargement of the cerebral ganglion. M. Viallanes has traced the conducting nerve from an elementary eye or facet of the external eye, through the succes- sive ganglia to the interior of the brain itself ; and he shows that the germs of all the parts which enter into the visual apparatus exist in the young larva, enclosed within the brain, which they after- wards leave to take on their definitive form and occupy their des- tined position. Horn on THE AnisoTomint.—Dr. Horn remarks (Entomologica Americana, Vol. 1, No. 3, 1885): In the genus Scotocryptus the tarsi on all the feet are three-jointed. To this character Dr. Sharp attributes considerable value, and makes it the sole ground- work for the separation of a tribe which he places between the Anisotomini and Cholevini. From my own studies this numeri- cal reduction of the several joints is only another step in the direction so plainly indicated in the genera already known. In Order that the idea may be more readily grasped, the genera may 1004 : General Notes.

It appears, according to the abstract in the Journal of the Royal Microscopical Society for August, that there are two distinct organs contained in each of these structures, one an auditory organ, the other an organ of problematical function, egos ) y e po ores Handbuch der Palzontologie relating to fossil has been prepared by Mr. S.

Ray LANKESTER’S CONTRIBUTIONS TO A KNOWLEDGE OF RHABDOPLEURA.!— The tube is secreted by the disk or epistome, is wholly external to the animal shut off into chambers, one for each polypide. ; The polypides present a body with the disk beneath it, mouth on either side under the disk, an arm with tentacles in a double row upon it, upon the opposite side of the body from the mouth the anus, body shaped like a sack with the intestine coiled and sur- mounted upon a stalk placed upon the mouth side. All this was known before. Lankester, by sections, demonstrates a space between the body wall and the gut wall partially filled with tis- sues, probably muscular and connective, which he calls the body cavity. The existence of a body cavity had not before been shown. Also upon the lower side of the main stack of the arms, near their base, L. finds a small ciliated pupilla which he thinks may be an osphradium. The lophophoral arms he considers the genetic equivalents uf the ctenidia of Mollusca. He demonstrates for the first time a sort of cartilaginous meso- blastic skeleton supporting the arms and the contractile cord. Finds the testis, not found by Allman or Sars, a blind sack open- ing by a special pore; this gonad belongs to Lankester’s idiodinic gonads, and is not at all a modified nephridium. Allman’s stat- oblasts are considered by Lankester to be undeveloped buds ; buds which from some debility failed to burst through the chitin- ous tube and mature. In the absence of information upon the embryology, the affinities of Rhabdopleura cannot be definitely spoken upon. If the disk is the homologue of the epistome of Bryozoa, then it cannot be the homologue of the molluscan foot, since its position is dorsal, not ventral, and we may consider it ‘homologous with the mantle, as suggested. by Allman.—Henry Leslie Osborn THE LARGE IGUANAS OF THE GREATER ANTILLES—The Jguana e M. cornutus is said to be from the same island, but the - authors of the Erpetologie Generale consider this uncertain.

By a course of reasoning based upon the examination of skulls in which ossification was defective at some point or other, this anatomist has found the quadrate bone of reptiles to be present in mammals in its normal position, but to synostose with the squamosal early in life; he has found the symplectic of the fish in the malleus of the mammal; he identifies the piscean hyoman- dibular with the incus, os orbiculare and stapes, basing his identi- fication on an actual division of the columella which is known to occur; he finds the metapterygoid transformed into the squamo- sal; while he sees the ectopterygoid of the fish in the mam- malian alisphenoid, the entopterygoid in the pterygoid and the preoperculum in the tympanic bones. MM. Serres, Rambaad, Renault and Ihering agree in homolo- gizing the postfrontal with the external orbital hypophysis of mammals, and M. Albrecht agrees in the identification. a communication relating to the “epipituitary spondylo- centers of the skull” he traces the remains of the primitive pas- sage of the dorsal chord through the series of vertebrae which form the basicranium. After leaving the basiotic part of the occipital, the passage, according to M. Albrecht, continues adove the hypophysis in the clivus (dorsum sella) of the basipost- sphenoid, and thence through the basipresphenoid, basiethmoid and basirhinoid or cartilage of the nose. M. Albrecht speaks of an adult mammal in which this basirhinoid was traversed throughout its whole length by the chorda dorsalis. In some cases (Rhinoceros tichorhinus) it may ossify as one bone, in others as a series of centers of vertebrae. Between these bones (cranio- the meta- and ectopterygoid bones with the alisphenoid and Squamosal, and of the quadrate with the lower part of the same temporal. The symplectic and hyomandibular have, according to our author (Sur la valeur morphologique de la trompe Eus- tache) nothing to do with the hyoid arch. The mere fact that the 1008 General Notes. | October, symplectic gives origin to the cartilage of Meckel shows that it must belong to the mandibular arch. Besides this, the hyoid arch, in the rays, is attached behind these bones. The relations of the hyoid and mandibular arches to each other are trace through the various classes, and M. Albrecht maintains that the metapterygoid (squamosal), quadrate (quadrate part of temporal), ectopterygoid (alisphenoid), entopterygoid (pterygoid) and pala- tines form a premandibular visceral arch or rib. From this it fol- lows that the spiracles (of selachians) and the eustachean tube are morphologically a premandibular branchial sac. Such branchie, in fact, exist in the spiracles of selachians. M. Albrecht has recently returned to the attack in the Bio- logischen Centralblatt, in which (iv Band, Nr 23) he endeavors to prove from Fig. 308 of Kolliker’s Entwicklungsgeschichte des Menschen und der hoheren Thiere, the correctness of his belief in the non-existence of Rathke’s pouch. In the same periodical, (v Band, Nr 5 and 6) he records the discovery of seven bony ver- tebral centers in the cartilaginous nasal septum of a full-grown cow. His figures certainly shows seven small bones, in so far approximating an anterior tail. In some observations recently made by our author before the Brussels Anthropological Society he treats of the posterior termina- tion of man’s vertebral column. Man, he says, is a tailless lower ape orlemur. Atavisms going back to the lemurs are more common in man than in any monkey. Through want of use he has lost “that registrar of the state of the mind,” the tail. Yet man has really six or seven caudal vertebrz, two anchylosed with the three sacral vertebre which enter into the sacro-iliac articulation, and four or five (in woman often five) coccygeal vertebra. M. Al- brecht maintains that post-coccygeal proto-vertebrz exist in some cases, and even believes in the occurrence of bone in the same region. In another article our author gives figures of the manubria of six examples of Mycetes. In one only is the manubrium entire, and M. Albrecht correlates the fissured manubrium with the . howling habit of this genus, necessitating space for the larynx. _ when this is not the case they are replaced by di- and par-apoph- = yses. Any adjacent pairs of ribs or costoids upon the same side may be conceived to unite while still cartilaginous. These two osite pairs may unite. Osseous tissue may develop in each 1885.| Zoölogy. f 1000 copula. This finally results in a sternebra which is intercostal, or intermediate between two successive pairs of ribs. A succes- sion of these intercostal copulæ between the true ribs form a sternum. Just as the true ribs are linked by copulæ that are in- termediate between two adjacent pairs, so are the costoids linked by intermediate copulæ, which may thus be distinguished as- intercostoidal paracopulæ and diacopulæ. These par- and dia- copulæ may develop between par- and diapophyses as well as- between par- and diacostoids. The views of M. Albrecht with regard to the evolution of what may be termed rib-junctions appear very plausible, but he coins some terrific polysyllables to explain their co-relations, as witness “ diparatetradiacopulaire.” This is worthy of organic chemistry, PRESENCE OF A TAIL IN THE HUMAN Empryo.—Does the human embryo ever present at the posterior extremity of its body any- thing which deserves the name of a fail? This question has given rise to a debate which has not failed to be a lively one be- cause necessary distinctions had not been made by the disputants,. and because they did not confine themselves to a strict definition of terms. _It is at the outset necessary to distinguish between teratologi- cal cases and normal embryological phenomena ; then it is neces- sary to agree as to the meaning of the word zai. Is this term applicable to any conical or cylindro-conical appendage of the posterior extremity of the back, formed of the tissues composing - it, or should we reserve it for an organ containing a prolongation of the vertebral column? It is this last definition which shou prevail; an appendage deprived of vertebrz is not a true tail in the anatomical sense of the word, but a simple caudal prolonga- ion In the teratological cases described by MM. L. Gerlach, Bar- tels and Ornstein, the appendage, sometimes filiform, sometimes voluminous, does not contain an incontestible vertebra, and the total number of these osseous pieces does not pass beyond the regular number of normal man. As regards young embryos it is impossible to decide the ques- tion if at the outset we do not determine the point where the caudal vertebra begin. Should we place the limit at the point where the tail leaves the body ? or should we be guided by the Position of the anus ? or better still should we call caudals all the vertebræ situated behind the sacrum? It is this last view which has prevailed in comparative anatomy, and we can say from this, point of view that adult man possesses a tail, since it presents four or five coccygeal vertebre situated behind the sacrum. The minimum, in this relation, is attained by the chimpanzee, which only two or three coccygeal vertebre. Should we wish to apply the name of tail to the portion of the - IOIO $ General Notes. [October, vertebral column situated behind the trunk, it would be necessary o bear in mind that from the age of three weeks and up to that of two months and onwards, the human embryo is fortified with this organ, because at this epoch the coccygeal vertebræ occupy the axis of a very distinct cylindrico-conical appendage, and which arises from the posterior extremity of the trunk. If, with M. His, we take for our guide the position of the anus, the tail will be shorter, but it will not cease to be very apparent, espe- cially at the age of five or six weeks. However, it is admitted as absolutely demonstrated, that this caudal appendage of the human embryo never contains any other vertebræ than those which are found in the coccyx of the adult. Ecker, who has given, with conviction, the name of tail to the posterior extremity of the human embryo, has declared that he has never met with supernumerary vertebrz. This authcr has him- self studied the tail, very well formed, of a human embryo of 9™™ in length, and he describes and figures all the terminal part as constituted of an unformed blastema. M. His found there, however, a prolongation of the dorsal cord and spinal marrow, but no segmentation. Both admit that beyond the thirty-third or thirty-fourth vertebra there is no other portion of the skele- ton. On this capital point my researches have led me to a result diametrically opposed to that of my predecessors. The errors of M. His arose from the fact that the embryos, the more advanced of which he made the reconstruction, those of 7™ and a fraction, have precisely thirty-four myomeres, viz., thirty-three vertebra, and he admits, without any other proof, that he was wordog over a definite stage. I have had the honor of presenting to the eae a résumé of my anatomical study of a human embryo of 5,8," viz., one twenty-five days old. This embryo had no more > than thirty- three somites, representing thirty-two vertebre. There is then an increase of the number during the fourth week. This fact led me to seek whether this number might not increase still more during the fifth week, and my attempt did not fail! The human. embryo of 9™™ to ro™ the age when the tail reaches its maxi- tie adil possesses a number of vertebre greater than that of the ALY m each other, since all three give the same result, n embryo of 8 to 9™™ has thirty-eight vertebræ. 1885.) Zoölogy. IOII This result is also confirmed by the examination of photo- graphs of fresh pieces, for then can be easily distinguished thir- ty-five myomeres and, besides, a region occupying the outer fourth of the tail, where the limits are no more- visible across the skin. But the sections prove to us that in this last quarter, con- trary to the opinion of Ecker and of M. His, the mesoderm is divided with the greatest clearness into a double series of somites which extend to the last extremity of the tail, but presenting, it is true, dimensions regularly decreasing up to the thirty-eighth somite, which does not measure more than thirty-seven microns in diameter. This fact is in no way teratological; it is plainly confirmed by several other embryos which I possess, all perfectly normal and of ages slightly different. ith the exception of the two last, all the caudal vertebrz have a blastema of a cartilaginous body similar, except in its dimensions, to that of any other vertebra of the series. The two last are only indicated by myomeres, perfectly distinct from the rest. The extremity even of the tail is formed by the termination of the medullary tube, only covered by the skin, The dorsal cord also extends very near this éxtremity. The last caudal vertebrze have only a very ephemeral existence ; already in embryos of 12™™ in length, viz., six weeks old, the thirth-eighth, thirty-seventh and thirty-sixth vertebre become confounded in a single mass, and the thirty-fifth itself is not per- fectly limited. An embryo 19™™ in length has no more than thirty-four vertebra, the thirty-fourth evidently resulting from the fusion of the last four; at this period the tail as a whole is already much less prominent. ; It results from these facts that the human embryo during the fifth and sixth week of its development, is provided with an un- doubted normal tail which in form is regularly conical, elongated and which deserves, under all relations, the name which I have given it. This organ, evidently deprived of all physiological utility, should be classed in the number of representative organs. —Professor H. Fol, in Comptes Rendus de l Acad.

ON THE GENESIS OF THE EXTRA TERMINAL PHALANGES IN THE Creracea.?—In what manner the extra terminal phalanges of the second, third and fourth digits of the manus of such a type as Globiocephalus amongst Cetaceans, was evolved, has been a question which my studies gave little hope of satisfactorily an- swering until I had noticed that the bony digits of both the manus and pes in the pinnipeds are prolonged into the flat ter- minal integuments of the limbs far beyond the nails as unseg- mented bars of cartilage, which are really unossified extensions of the ungual phalanges. The nails are borne upon the dorsal aspect of the ungual phalanges in pinnipeds, the ossified shafts of these phalanges usually ending abruptly to be continued into the terminal bars of cartilage. In Histriophoca the terminal cartilag- inous extension of the last joints of the digits are quite rudimen- tary, but the point where the ungual phalanges abut distally upon the terminal cartilages is still visibly marked in this species. In the walrus, the fur-seal and sea-lion the terminal cartilages of the igits are more developed, and articulate directly with the ab- ruptly truncated ends of the ungual phalanges, In the manatee the ungual phalanges of the manus terminate abruptly ; that they support cartilaginous extensions of notable length seems improb- able. The terminal cartilages of the digit apparently reach their greatest or strongest development in the walrus. The foregoing data when interpreted by the aid of embryolog- ical theory, as actually observed to hold in other forms, and linked with the explanations afforded by other facts which will be given later on, will, it seems to the writer, gives us a rational hypothe- — sis of the origin of the extra-terminal digits in the manus of the ee whales. Edited by Joun A. RYDER, Smithsonian Institution, Washington, D.C. ; This note presents the substance of conclusions reached by me in my memoir en- titled, «On the development of the Cetacea, together with a consideration of the Probable homologies of the flukes of cetaceans and sirenians,’’ now in press IOI4 General Notes. [October, That the digits of the Cetacea develop as part of the continu- ous blastema of the embryonic appendicular skeleton as in other vertebrated animals, there can be no doubt. That the joints and segments of their limbs also become gradually defined in serial order from the shoulder and hip girdles outward, also admits of no doubt, as may be seen upon studying sections of the manus, a quarter inch in length, of a foetal Globiocephalus two inches in total length. In like manner there can be no doubt of the fact that the cartilaginous extensions of the ungual phalanges of pin- nipeds are a part of the original blastema from which the ossified portions of the skeleton of the limbs of these animals has de- veloped. In man ,the shafts of the three phalangeal segments of the digits of the manus ossify almost contemporaneously. In Globio- cephalus, on the other hand, in a specimen one-third grown, it is found that the proximal segments of the second and third digits ossify apparently at about the same time as their isomeres in the first, fourth and fifth digits, whereas the distal or extra peripheral segments develop ossific centers enchrondrally much later. These development and ossification of the extra terminal digits of the existing whales. In fact, in some of the existing seals these car- tilaginous prolongations of the ungual phalanges are long enough in the pes to afford the basis for three new and additional seg- _ ments to each digit, as long as the three normally developed in each toe. . __ The proof that the extra terminal segments of the digits of he cetacean manus have been added distally, is the fact that the structure of the carpus is not, in any essential feature, different ure from that of other mammals so far as the presence or b 1885.] Embryology. IO15 absence of elements normally formed is concerned. I am there- fore constrained to believe that it has been through a seal-like ancestry with prolonged integuments to the manus, in which the nails were not terminal but dorsal, beyond which the ungual pha- langes were extended as bars of cartilage, which gave rise, by transverse segmentation and subsequent ossification to extra ter- minal digital segments as found in existing Cetacea. The second fact of importance to be considered as lending probability to the foregoing view is the circumstance that when a limb is in its primitive cartilaginous condition it always devel- ops its segments from its axial end toward its peripheral end in serial order. The basis for the extra terminal segments was first developed through the influence of functional adaptation, as car- tilaginous bars or extensions of the primitive cartilage of the ungual elements of the digits in response to the demands made upon the limb in swimming. The segmentation of these terminal cartilaginous bars then followed through the influence of mechan- ical strains acting upon the cartilaginous terminal bars as these were alternately bent in opposite directions. These conclusions might be still further illustrated by data obtained from the obser- vation of the development of the limbs of other animals. These views, very forcibly it seems to me, sustain the hypoth- esis that the Cetacea are the off-shoots of land forms which were at first terrestrial, or at least amphibious, as are the pinnipeds. Such views do not at least run counter to any morphological facts, but in reality are sustained by them.— Fohn A. Ryder. ON THE MANNER IN WHICH THE CAVITY OF THE HEART IS FORMED IN CERTAIN TELEOsTS.— Balfour (Comp. Embryol., 1, 523) states that “ in Teleostei the heart is formed as in birds and mammals by the coalescence of two tubes, and it arises before the formation of the throat.” I would now point out that this is not universally true of all teleostean forms, in fact it seems not to be the mode of cardiac development in any species of this group so far investigated. My own observations on this point have been made upon the embryo cod-fish and indicate very conclusively, so far as trans- parent views are of value in deciding such a difficult matter, that the lumen of the heart arises asa single and not as a double cavity which afterwards blends to form a single one, as in birds and Mammalia. Moreover, this cavity is from the first open below, and is present in the cod embryo, on the fifteenth day, as a round opening limited all round by mesoblastic cells. Its transverse diameter at this stage is .043™™ and is probably half as cep. It has the appearance of a round perforation in the meso- blastic plate of cells which probably gives rise to the endothel- lum of the cardiac cavity, the lining of the pericardial cavity and * Contrib. Embryog. Oss. Fishes, pp. 82-86. 1016 General Notes. [October, muscular wall of the heart, and which underlies the fore-gut as a transverse band of tissue. The cardiac lumen, as observed by myself to appear in the living embryo, occupies, ad initio, such a position that the median vertical plane passing through the em- bryo lengthwise would divide it. Its floor, which corresponds to its future venous end, seems to be devoid of cells, and is formed apparently by the periblast cov- ering the yolk. In the later stages of cardiac development in forms which have no complete circulation at the time of hatching, this is invariably the case, the venous end of the heart opening directly upon the surface of the periblast, as is shown in longi- tudinal sections of such stages. As elsewhere stated, the yolk is here absolutely excluded from the intestine, and the arrangement above described then provides the passage-way for yolk material into the general circulation as it is segmented off from the periblast, as shown by Kupffer, Gensch and myself. This also bring the segmentation cavity and the blood vascular channels into actual continuity. The investigations of Hoffmann! upon the development of the heart in Salmo are based entirely on sections, and begin with a stage long prior to the time when the organ begins to pulsate, and corresponds pretty closely to the stage of development seen in the cod embryo described above, which was observed about two days before pulsation began, when the heart became for the first time distinctly tubular, its lumen in the early stage here con- sidered, being a mere flat, discoidal vacuole with vertical side- walls formed of cells. At a later stage of development the axis of the lumen of the cardiac cavity is horizontal instead of vertical. Hoffman concludes that the endothelium of the heart is derived from the hypoblast, in which a short tubular cavity at once ap- pears, the long axis of this endothelial tube coinciding in direc- tion with the axis of the embryo. The myocardium or muscular outer wall of the heart is derived from the splanchnopleural _ plates which grow on either side of the embryo from above down- wards and inward under the fore-gut, below which they approxi- mate, their free ends finally investing the endothelial vesicle or tube, which represents in the salmon the vacuole above described in the cod embryo, which is the first trace of the cardiac lumen. After the muscular layer of the heart is supplied by the splanch- nopleural plates, the foundation of the structure of the adult _ heart has been laid. : = — In neither of the foregoing accounts is there anything which _ Suggests very much similarity between the mode of development _ of the first traces of the unpaired rudiment of the teleostean heart and that of Aves or Mammalia which arises by the fusion the median line of a pair of cavities on either side of the lat- enie der Knochenfische, Pts. vir, viii.

Currosity oF Monkeys.—“ Do monkeys learn by experience?” is asked in your last number by Mr. W. H. Frost, who cites cats as learning in regard to their reflection in a mirror, and further states that it is claimed, on tolerable good authority, that mon- keys never do, which statement he does not attempt to answer. It seems to me that the probable explanation of the difference of action of the two animals in the matter is due, not to the su- perior powers of discernment, and capacity of learning by expe- rience possessed by the cat, as one would infer from the article mentioned, but just the reverse. I should doubt very much but that the monkey realizes in time that there is no other individual behind the glass, and think that its actions are simply due to the greater mental development which it possesses, and which is largely manifested by its investi- gative turn of mind, and could we understand the monkey lan- guage, it would tell us that it was a problem which it was trying to work out, and that while it felt that it was no genuine or ordi- nary monkey which appeared in the glass, it was curious to find out just what it was. The monkey’s mind, from long experience, has an innate con- sciousness of power to solve many of the problems presented to it, and being in a comparatively active state of evolution, is con- tinually grasping out at new ideas. : e cat’s mind, on the other hand, is not of such a progressive type, and consequently it quietly gives up many problems with “T cannot comprehend,” and ceases to “ bother its head about it, simply accepting the problem as it appears to it—a harmless, un- oT phenomenon.—Lugene N.

IOIQ Texan Movunps.—Mr. Pierce, Episcopalian bishop of Little Rock, Ark., states that in the old bottom of Red river, south of its present course, between Rocky Comfort, Ark., and De Kalb} Texas, an extensive series of unexplored mounds can be: found. When he saw these mounds, while riding by in a carriage, they appeared to him of almost uniform size and flat on the top, about sixty feet wide and eighty long, with a height varying from eight to twelve feet. They were oval with the long sides lying parallel to each other, and a portion of them projected into the brush- wood, so as to be only partially visible. To state the number of these artificial structures is impossible, but it took an hours’ ride before he had passed the last of them. ANTHROPOLOGICAL COLLECTORS.—In every department of sci- ence one of the most valuable requisites is the collector. When his material is assorted and put away for research or put on exhi- bition for educational purposes, almost the only value which the specimens have is the little piece of papet he attaches to them. It is well known that specimens are assorted and arranged by certain classific concepts, such as locality, tribe, structure, func- tion, and evolution. Now, suppose a collector is going over the eastern, or the western coast of North America, and from one place brings a large quantity of mortars and pestles, from an- other, basket work in the greatest profusion, from another, pot- tery, and from a fourth, bows and arrows of a pattern which he regards as unique. These are brought home and laid on tables according to the locality concept. We see at once what a chap- ter in human history we can write. Tribe A grinds its food, tribe B does nothing but make baskets, tribe C has no other ves- sels but pots, and tribe D is altogether addicted to the chase. It is impossible to say beforehand to a collector, get this or that, for we do not know what he is going to find. If we say, get everything, or at least a sample of everything, he is at a loss to decide which to select. One very good rule for a collector to follow is, Perfect each observation, It is better to know all about something than to know a little about everything. “Blessed is the man that’s well smattered,” does not apply to collections. In the case of any human art whatever, it is essential to have the raw material, together with accurate descriptions of all the cus- toms and superstitions connected with its procurement and prep- aration. The next thing is to find out who are the agents, men or women? all or some? always or sometimes? everywhere or somewhere? This should be followed by the scrupulous pro- curement of all the tools used in all the steps from exploitation exchange or consumption. Nor would these be very useful without photographs, models, and descriptions of all the pro- cesses involved, without, in short, exhaustively answering the 1 Bowie county, Texas. 1020 General Notes. [October, question “ow. Finally, the finished product of each art should be procured in all the types of its manifestation. I know one man who collects only the rudest products of each art. I know many more who are wasting fortunes on chef d'œuvres, and, I am proud to say, there are very many private collectors who are en- gaged in exhausting a special theme up to the limit of their means. In 1875 I prepared a little pamphlet for Centennial col- lectors in which I dwelt particularly upon this point. Some of the material procured for that great exhibit was gathered by the rule that we must have all of a thing or none. Lately some of the mound-explorers have proceeded on the same plan. But, alas, the old raking-in process is also largely in vogue, and future museum students will have a happy time in guessing what man- ner of people those ancients were. I have lately opened a large lot of relics from old Peruvian cemeteries, in which the transmit- ter says, “ You will doubtless know all about these things.” In emptying some of the pots and gourds I came across a large beetle, nearly two inches long, transfixed with an entomologist’s pin, the latter very much rusted. Now, can any body tell me whether the Incas were so advanced in culture as to make collec- tions of insects and to preserve them on pins exactly like those in use forty years ago? ~ Anthropology is fast becoming an exact science, thanks to the noble army of collectors who have known how to see, delineate, collect and describe ; but there is still room for improvement. I o not mean that we must become the victims of professional collectors, The much better way is for every lover and student of this science to exercise the greatest wisdom on his own behalf, to do his own collecting as far as possible, and to submit other material to the most rigid scrutiny. Puyaus In SuTLEJ VALLEY.—In nearly every Himalayan village there is a house for the representation of the local divinity. In front is a shed formed of four pillars, and a roof of wood orna- mented in the style of the temple. This is both a resting place The ceremony was a pecu- dance in the porch of the temple, during which the devi was ied round by two men facing each other. The villagers faced litter in a semicircle, their arms intertwined. The end man By 1885,] Microscopy. - 1021 had his right hand free, and in it he held a chowrie (brush of yak’s tails) with which he kept time. At another ceremony an old man in the red robe of a lama approached the devi, and fruit, and bread. A number of birds, some black, some white, were killed, and the blood sprinkled on the devi, afterwards the rest was dashed over the building. A part of the service was a mock battle with walnuts and pine cones, between the priest and his attendants from the balcony of the temple, and the people be- low. Meanwhile the birds were cooked, and they are now served, the women eating first. The devis have a way of intimating when they wish to go visiting. The reception of one devi by another is like two rajahs meeting. There is a great amount of bowing and shaking which terminates in the host getting behind and the procession marching to the village temple. When the visitor returns home the host accompanies it to the borders of the village. Mr. Simpson, who describes the pujah ceremonies first draws attention to the ark and sacrifices of the Jews and the Egyptians, and then views with more favor the car-festival as the parent of these primitive services. To most people unacquainted with India the rath yatra, or car-festival, is associated only with Jagganath, at Puri, but this is not so; cars are kept in the tem- ples over the whole of Southern India. Although not connected with Hinduism, the Buddhists also had a similar festival. If it was common to the whole of India, it is easy to see that where there were no roads for a car on wheels, the god would have to be carried on men’s shoulders, and the size would be reduced to Suit circumstances. At one of the pujahs a Brahmin walked barefooted thirty steps on the sharp edges of hatchets—% R. A. Soc., XVI, 13-30. Tue Kansas City Review.—One of our best sources of infor- mation respecting the archæology of the Missouri region, is the Kansas City Review. The editor, Mr. Theo. S. Case, has con- ducted this journal for seven years, at considerable expense to himself, in order to contribute his share towards the intellectual improvement of his section. There is a rumor that the Review is in danger of stopping through want of patronage. We regret to hear this very much. The late Dr. Ruggles said to the writer On one occasion, “I do not read half the books and magazines I buy. I take them because I am afraid the authors would suffer without my little help.” Now this is one motive, and there are many more why we should not let good scientific literature lan- guish through lack of our aid.

Comparative Zoology, Cambridge, Mass. 1022 General Notes. [October, posited in white silky cocoons, which are attached to the under side of loosened bark, fence boards, and other sheltered places. They are very abundant in September and October, and during the entire winter cocoons may be found with eggs in early stages of development. This species thrives well in captivity, so that there is no difficulty in obtaining eggs freshly laid. For studying the egg in a living condition the long-used method of immersion in oil is excellent. The oil should be per- fectly clear and odorless. The external features can be studied to better advantage by mounting the eggs in alcohol after they have been freed from the chorion and stained. Another valuable method for surface study consists in clearing the already stained egg in clove oil. The thickness of the blastoderm is most easily determined in this way. The best method of hardening preparatory to sectioning is that of heating in water to about 80° C., and then, after cooling slowly, treating with the usual grades of alcohol. Good results were obtained with Perenyi’s fluid, which rendered the yolk less brit- tle. Osmic acid does not penetrate the chorion, and chromic acid or acid alcohol are not easily soaked out on account of the thickness of the chorion. š Borax-carmine proved, on the whole, to be the best staining fluid. It is difficult to make the dye penetrate the chorion, and, after hatching, the cuticula forms a similar obstacle. This iffi- culty. may be overcome by prolonged immersion in the staining fluid. In some cases seventy-two hours were required to obtain a sufficient depth of color. In order to avoid maceration, which would result from so long continued immersion in a weak alco- holic dye, the staining process may be interrupted at the end of every twenty-four hours, by transferring to seventy per cent alco- hol for an hour or more. After most methods of hardening, the yolk becomes very brit- tle, and the sections crumble. This difficulty may be overcome by collodionizing the cut surface before making each’ section, in the manner described by Dr. Mark (Amer. NATURALIST, June, 1885)\— Wm. A. Locy.

The position of the ob- ject is such that it can not be conveniently watched during the 1024 General Notes. [ October, process. of cutting; and this appears to me to form another se- rious objection to the instrument. The construction of the instrument is as follows: Two up- rights are cast on the base plate of the instrument, and are pro- vided with slots at the top, into which the razor is placed and clamped by two screws with milled heads. The imbedded object is cemented with paraffine into a brass tube which fits tightly on to the end of a cast-iron lever. This tube can be made to slide backwards or forwards so as to bring the imbedded object near to the razor ready for adjusting. The cast-iron lever is pivoted at about three inches from the end of the tube. To the other end of this lever is attached a cord by which the motion is given and the object to be cut brought across the edge of the razor. The bearings of the pivot are V- shaped grooves which themselves form part of another pivoted system. Immediately under the first pair of V’s is another pair of in- verted V’s, which rest on a rod fixed to two uprights cast on the base plate. A horizontal arm projects at right angles to the plane of the two sets of V’s, the whole being parts of the same casting. On the end of the horizontal arm is a boss with a hole in it, through which a screw passes freely. The bottom of the oss is turned out spherically, and into it fits a spherical nut working on the screw. The bottom of the screw rests on a pin fixed in the base plate. : It will be seen that the effect of turning the screw is to raise or lower the end of the horizontal arm, and therefore to move backwards or forwards the upper pair of V’s, and with them the lever and object to be cut. The top of the screw is provided with a milled head, which may be used to adjust the object to the cutting distance. í - The distance between the centers of the two pivoted systems 15 one inch, and the distance of the screw from the fixed rod is six and a quarter inches. The thread of the screw is twenty-five to the inch ; thus if the screw is turned once round, the object to I be cut will be moved forward 3: of 617 or rte of an inch. | 1885.] Scientific News. $ 1025 varied from a minimum, depending on the perfection with which the razor is sharpened, to a maximum of 3% of zg of z or ory ofa turn.

This string passes under a pulley and is fastened to the arm carryin the pawl. Attached to the other end of the lever is a spring pull- ing downwards. ~- en the arm is moved forwards the feed takes place, the string is pulled, the embedded object is raised past the razor, and the string is stretched. When the arm is allowed to move back the spring draws the imbedded object across the edge of the razor, and the section is cut. The string is attached to the lever by a screw which allows the position of the embedded object to be adjusted so that, at the end of the forward stroke, it is only Just past the edge of the razor. This is an important adjustment, as it causes the razor to commence the cut when the object is traveling slowly, and produces the most favorable conditions for the sections to adhere to each other. :0: SCIENTIFIC NEWS. — To the report of the Commissioner of Fisheries of New York in charge of the oyster investigation is appended Dr. H.

HOLMES. an E two great centers of aboriginal American culture, Mexico and Peru, were the first to feel the shock of the conquest, and the native peoples, together with their arts and institutions, sank at once into irretrievable ruin. Temples, sculptures and paint- ings, the tangible representatives of an idolatrous worship, ex- cited the hatred of a fanatical priesthood, and were, as nearly as possible, swept from the face of the land. The fiercely intolerant Spirit of the representatives of the church is well illustrated by the language of a letter written by Zumarraga, the chief inquisi- tor of Mexico, to the Franciscan chapter at Tolosa, in January, 1531. The words are as follows: “ Very reverend Father be it known to you that we are very busy in the work of converting the heathen; of whom, by the grace of God, upwards of one million have been baptized at the hands of the brethren of the order of our Seraphic Father, Saint Francis; five hundred tem- ples have been leveled to the ground, and more than twenty thousand figures of the devils they worshiped have been broken to pieces and burned.” : There was, however, a limit to the power of destruction. Many of the greater monuments have defied the destroyer and stand to-day and will stand for ages to come as illustrations of the Power and culture of their builders.

There remain but traces of walls and floors, the deep recesses cut in the solid rock and the great battered boulders that were once the images of gods, to tell imperfectly _ the story of a blasted culture. _ Among the most interesting of these remnants is a recess 4 a short distance below the summit on the side facing Texcoco, and Se ee ee ee aa ` i 4 l i 1885.] Iconoclasm by the Conquerors of Mexico, 1033 the first place it must be described in detail. In beginning an edifice or apartment on the face of the hill, it was necessary first to prepare a floor by cutting a niche into the rock and filling out the level with masonry and cement! until a proper platform was secured. The back wall was formed entirely of the living rock and afforded the opportunity of carving out the deity who was to preside over the place. The side walls are partially of the rock in place, and were completed by the addition of heavy masonry, portions of which are still to be seen. Fic. 2.—Sketch of fragment of idol. On the floor of this recess I came upon a large fragment of rock that exhibited evidence of having been elaborately sculp- tured, and which at first suggested the figures peculiar to the calendar stones of the museum at Mexico. The fragment is nearly four feet long, by about three wide and half that thick. e sculpture is confined to one face, the sides and back showing rather fresh irregular fracture. In making a sketch of the block I observed first that the fig- ures were not symmetrically arranged and not truly radiate, and 1A common lime-sand cement, as determined by Professor F.

This led to the search for other features, and finally to the discovery of a partially obliterated eye toward the smaller end of the fragment. This convinced me that the object was part of the head of a huge idol. My sketch is reproduced in Fig. 2, but gives a very imperfect idea of the work, which in pre- cision of execution and delicacy of finish equals anything of its class yet brought to my notice. It is a remarkable fact that the surface of the carving has been finished with a coat of red paint or enamel, which to this day exhibits a saat polish, and is so a i X £. a UG Se ma / ZW N = A D \ \ ) =) an sien” Teann = a e ay) i a th TAN Fic. 3.—Probable position of the idol at the back of the niche. firmly attached to the rock surface as to be removed with the greatest difficulty. The other portions of the figure have been broken up and carried away, or have been rolled down the side of the cerro. At first I was at a loss to imagine the original character and position of the figure to which the head belonged, but after a careful study of the recess I came to the conclusion that it had originally occupied the back wall of the recess, and that it had been carved from the rock in place. The proof of this : was entirely satisfactory. sl observed first that the central part of the rear wall was not othly ee. and that the rock surface showed compara 1885.] Lconoclasm by the Conquerors of Mexico. 1035 tively recent fracture. In examining it closely I found at the base, as shown in the sketch, Fig. 3, an undercut channel, in and in front of which, after clearing away the earth, I detected a pair of feet carved in the rock, They were badly mutilated but still showed traces of the toes and portions of the sandals, These feet had originally formed part of a complete figure, and the fragment of head found on the floor had belonged to it. Another pair of feet at the right, still more completely oblit- erated, indicated the position of a second figure. The fragment shown in Fig, 2 lies on the floor at a, Fig. 3, and doubtless originally occupied nearly the position in the wall indicated in the sketch. These figures had been wedged or blown off and broken up by the Spaniards, and the whole shrine dismantled. There are other recesses of similar character in this hill, which show like treatment by the conquerors or their descen- dants. One at the opposite end of the crest, near the terminus of the great causeway, is said to have hada calendar carved in the living rock of the rear wall, a spot now exhibiting a deep irregular excavation thought to have been made by treasure hunters.! In this connection it is convenient to mention a remark- able piece of work, a block of curiously carved andesite that rests upon the outer extremity of the crest of the hill. Although in such a prominent place it is partially obscured by trees of _ Copal, etc., and would escape the attention of the casual ob- Server; besides, the sledge of the destroyer has obliterated much of the evidence of art. In order to preserve a memoran- dum of the work, I stood upon a contiguous rock and made the sketch presented in Fig. 4, my line of vision being at an angle of 45° with the flat surface of the stone, c c, which is horizontally placed. The surface has been cut down, leveled and finished with a pointed implement, leaving a pecked or granular surface, while the middle portion of the rock was left in relief and carved into the curious form indicated in the sketch, but which has been almost completely obliterated by the hammer of the despoiler. e query arises, what has this rock been, and what its func- tion, that the godly missionaries should have endeavored to de- Stroy it? * For details see Bancroft’s Native Races and works cited by him. 1036 Iconoclasm by the Conquerors of Mexico, {November, I was struck at first sight, although without previous thought of the matter, that here was a stone perfectly suited for the offer- ing of human sacrifice.

I present this instance as at least a plausible case. The Texcocan monarch is said to have climbed the 500 steps that led to the summit to worship an idol that stood there, and it is said that this idol, hewn from the living rock, was the image of a coyote, the emblem of Nezahualcoyotl, the King. Since, however, human sacrifice is acknowledged to have been extensively practiced by these people, it strikes me that in no other locality could we more readily expect to find the material evidence of the existence of such a practice as on the summit of this wonderful hill, a point which overlooked the whole valley of Mexico, and which seems to have been almost wholly devoted to the service of the gods. ier n THE PRESENT CONDITION OF THE YELLOWSTONE NATIONAL PARK. BY E. D: CQPE. iew has fully justified the enterprise of Dr. Hayden in urging upon Congress the project of the creation of the Yellowstone National Park; and the protection of this and other especially interesting Serta of our country by the arm of the National Government has met with almost unanimous approval. The function of the Yellowstone Park may be looked on as three-fold: first, as a place of permanent preservation of the gey- sers and hot springs and their deposits; second, as a place of protection of the game of the country; and third, as a place of recreation for tourists. The first of these uses has always been uppermost. The second has been more and more engaging the attention of Congress, and the NATURALIST published an editorial in its issue of July, 1884, pressing on public attention the ne- cessity of making it a more complete preserve for game than it had previously been. This article was reprinted; and later, Our contemporary, Science, took up the subject editorially. As a probable consequence of this agitation a bill was introduced into Congress, last winter, providing for a more complete super- Vision of the territory of the park. Ten men witha gamekeeper and the superintendent, constitute the present force. As this was manifestly insufficient to police a territory of such great extent, the new bill contemplated the addition of fifteen men to the num- 1038 Condition of the Yellowstone National Park. (November, ber, thus increasing the police to twenty-five men. Their salaries were fixed by the new bill at $1500 per annum. The sum now paid is $900, from which the men are expected to feed themselves, an important consideration in so expensive a region. This bill was not passed. Since the attention of Congress and of the press has, been directed to the park, the protection of its beauties and curiosities has been more efficient. A number of persons have been fined for breaking the geyser deposits, including at least one member of Congress. In this respect the protection may be considered to be now fairly good. Protection of game has been less suc- cessful because more difficult, and because of the great inade- quacy of the force. Bison, elk, moose, deer, etc., are far less abundant than when the park was first created. The bison have been, I am informed, reduced to a herd of about sixty individuals, and the elk have been decimated. The moose are confined to a small region. From the inaccessible nature of their habitat, mountain sheep have not been so reduced in numbers. Protec- tion has, however, become more definite in this direction. During the past year several persons have been fined from $75 to $100, and one old hunter, who defied the guards, was caught, fined $100, and imprisoned for six months. _These measures of protection can, however, only be carried into effect by an increase in the force and their proper distribu- tion throughout the territory. Persons may now hunt undetected in the park, and may drive game outside of its boundaries with- out difficulty and kill it. The disposition to kill is not controlled by any considerations of decency in some men. Thus a party of English shooters killed, for their amusement, twenty or thirty from the bison herd without taking any part of the animals for _ their use, thus reducing their numbers by one-fourth at least, at one battue. Some persons state that protection is useless because the game leaves the park in winter. This I ascertained is not true, for there are numerous well-protected localities where the game winter safely. - ohe bin which was brought before Congress last winter for the - more efficient protection of the park should be passed by the gress of 1885-6, with some possible amendments. Thus the > should be increased to twenty-five men, each with a salary 000 per annum exclusive of his food and boarding. The 1885.] Condition of the Yellowstone National Park. 1039 park should be divided into twenty-five parts, each one supervised by one of the guards with perhaps an assistant or roustabout. A simple house for the guard should be erected in each one of the divisions, and the guard should reside there through both winter and summer, and not be permitted, as is now the case, to come into the settlements and remain there during the winter. It is well known that large game may be more readily destroyed in winter than insummer. Those guards whose districts include the geysers will naturally be more occupied with the protection of these objects than the protection of the game, as the one is generally abundant inversely to the other. Visitors should not be permitted to carry guns or other hunting apparatus through the park, and should be required to deposit them with some designated person to be held during their stay in it. A project for reducing the size of the park has already been introduced into Congress. This is in order to permit the con- struction of a railroad to the Clark’s Fork mining camp, through the park via the Yellowstone, the East Fork, and Soda Butte creek, As the law creating the park forbids the passage of railroads through it, it is sought to alienate a tract of land from the park, of a triangular shape, of about forty miles in length and twelve to fifteen miles wide at the widest part. An examination of the map will show that the direct route from the Clark’s Fork mines to the Northern Pacific railroad is not more than one-tenth as long as the one proposed to pass through the park, so that it is difficult to guess at the motive which prompts the proposition in view. The project should be subjected to the most rigid - examination, as any alienation of the territory of the park seems to be unnecessary. On the other hand much greater security as a game preserve would be accomplished if the region on the south-east border of the park, which includes the Hoodoo moun- tains, were annexed to it. It is the headquarters of the game of the country, and that of the park frequently resorts to it. It is excessively rugged, and is nearly useless to man for any other Purpose. As regards the entertainment of tourists, the administration of the new superintendent, Mr. Weare, has been a great improve- ment over that of his predecessor. The monopoly of transpor- tation, sought to be established, has been abolished, and compe- tition is free to guides and hotel-keepers. This has the 1040 An Observation on the Hybridization |November, effect of reducing rates, and will do so still more, for the charges have not yet reached bed-rock. When this desirable result ha’ been achieved, the Yellowstone National Park will become one of the most popular resorts for tourists of all nations, who will be amply repaid by an inspection of one of the few remaining regions of the earth where thermal activity still reaches its sur- face, and of the grand and impressive scenery which surrounds it. A’ oe AN OBSERVATION ON THE HYBRIDIZATION AND CROSS-BREEDING OF PLANTS! BY E, LEWIS STURTEVANT, M.D. EORG von Martens, in his Gartenbohnen, Ravensburg, 1869, p- 35, under Phaseolus Pardus virescens, the graugrune pan- therbohne, says: “I was very much surprised to obtain not less than eight varieties of beans, die incarnatbohne, die dottergelbe- bohne, die weissebohne, die amethystfarbige zebrabohne, die graugrune pantherbohne, die helle pantherbohne, die gelbge- fleckte pantherbohne, and the princessinbohne. With more tho- rough investigation I decided that the zebrabohne was most likely a neighbor which had overrun the bed, but all the others came from the bed, and some, the incarnatbohne and the weisse- bohne had not been planted in the whole garden.” Martens might have expressed surprise that these varieties from the seed of the graugrune pantherbohne were all towards named varieties rather than sports or intermediates, but this fact, which frequently appears noted in his book, does not receive attention as being of any importance. At the New York Agricultural Experiment Station, in 1882, a few oblong beans, slightly flattened sidewise and mottled in two shades of brown, were selected from the yield of the golden cranberry. This selection, planted by itself in 1883, gave eleven distinct forms, many of which can be referred to named varieties, and possibly with a greater acquaintance with varieties all might be so referred; an illustration confirmatory of the results above noted by Martens, and is strengthened by a list of similar occur- - rences with other varieties in 1883 numbering a score. ~ This fact of named varieties being produced from seed of other "varieties i is not confined to the bean family alone. The following * Read before section F, A. A. A, S. at the Ann Arbor meeting. 1885. | and Cross-Breeding of Plants. 1041 list includes similar occurrences noted at the New York Agricul- tural Experiment Station during the last three years: Maize—Seed of one kind sown often produces samples of other kinds of corn in the crop, and these varieties can usually be distinctly referred by name to varieties with which the original seed might have been crossed. Purposely hybridized seed has produced the original parentage without intermediate types, and seed exposed to hybridization during two years with many sorts of corn, has yielded ears of the types of corn with which cross- breeding or hybridization has been effected, without appearance of intermediate forms. Barley —April, 1884, one head of cross-bred awnless barley was received from Mr. Horsford, a seed-grower in Vermont. The yield of the twenty-six seed was four distinct sorts of barley; one beardless black, one beardless white, one bearded black and one bearded white. One peculiarity was, that the beardless forms could be referred to Hordeum trifurcatum, There were no inter- mediates in this crop. Peppers.—In 1882 eleven varieties of peppers were grown; in 1883, nineteen varieties. The pepper plant is extremely variable. The fruit on different plants of the same variety often varies much in shape; on some the fruit is borne erect, on others pen- dant; certain plants of a variety often mature their fruit much earlier than do others. These facts, as well as direct observation, certify to the ready cross-fertilization between varieties. Yet despite this apparent cross-fertilization, varieties by selection are kept true to name, and almost all or perhaps all of the various “sporting” forms noted by us are found illustrated in Hortus Eystettensis, 1613, a fact which brings the pepper in line with our other illustrations. Tomato’—In 1882 the French upright tomato was crossed with 1Some additional observations of a later date than those given in this paper are as follows Melom-—The Christiana melon seed used in 1885 was from two sources. The one Seed pure and the crop all on type; the other seed station-grown in 1883 and sub- jected to a possible cross-fertilization with other varieties; the produce from this Seed gave this year fruit mostly of pure Christiana type, but some plants yielded fruit of the early white Japan, long Persian and Hackensack types, and no interme- diates. These off-varieties were among the melon varieties of 1883, and by which there was a possibility of the Christiana being crossed through insect agency. Tomato,—In 1883 the French upright tomato was crossed by the Livingston’s favorite, and the crossed seed has been attempted to be grown in purity up to date, 1042 An Observation on the Hybridization [November, pollen from the alpha and Livingston’s favorite. The produce from the cross-breds was one plant of the French upright, a hun- dred or more of the common form, and no intermediates. The fruit was all clustered, however, and of one type of bearing. The types of the tomato fruit have not as yet been sufficiently studied by us to allow of a judgment upon variability in this respect. Squash. —In 1883 the perfect gem and vegetable marrow squashes were crossed in both directions. The seed planted in 1884 gave good types of the cocoanut, green-striped bergen and the courge d'Italie varieties. In 1883, the year the seed was saved, we had no plants of these varieties upon the station grounds. There were also some unknown forms, but none that could be called strictly intermediate between the varieties, and some which represented each parentage. Lettuce —In 1883 the green fringed and the deer tongue lettuce was crossed. In 1884 the crop yielded forms which could be referred to the Batavian, Silesian and Malta drumhead varieties, This year is hence the second generation from the cross. The number of plants under observation have been numerous, occupying three-twentieths of anacre. The types of the plants are French upright and the common, without intermediate forms. The types of the fruit are French upright, Livingston’s favorite, common red and great Chihuahua, and no intermediates that can be recognized. The last-named is precisely on type both in plant and fruit, but few plants as compared with the others. French upright crossed by acme. First generation. The types of plant either French moe or acme. The fruit acme, French upright and common red, and no interm French ek crossed by alpha. Second generation, The type of plant both kinds.

Currant crossed by Livingston’s favorite. First generation. The types of plant mostly the currant, but some few plants of the common: form, but slightly more up- right. The fruit is racemed like the currant, but of far larger size, about 114 inch in diameter. Although I have never seen fruit of this character before, yet the plant and the fruit correspond very closely with the description of the Solanum racemosum : forma of Bauhin’s Prodromus, ed. of 1671, p. 90; and we may legitimately _ Suspect atavism has reproduced this apparently lost variety. _ Turks cap-crossed by several large varieties in 1882, such as acme, trophy, may- flower and paragon.

In this case we had the parents of two very distinct types, there being scarcely a point of resemblance in general appearance. Pea—In 1883 we had crosses between the sugar pea and the common pea. The 1884 crop from the crossed seed had the seed all of the sugar pea type, the pods all of the common type. The wrinkled pea crossed with the smooth pea gave wrinkled and smooth peas in the same pod, but no merging of the two forms. These facts of careful observation and record are only explain- able by the hypothesis that in certain kinds of cross-fertilizations and hybridizations the tendency of the crossed seed is to repro- duce ancestral forms rather than intermediate forms. That there can be a blending of characters in certain cases is well known or certainly well asserted; but in the experience gained at the New York Agricultural Experiment Station, “sports” or blendings are rare in exact accordance with our familiarity with varieties. - Thus in the case of the maize, at first we had many cases noted in our collection as variables; with the increase of varieties grown, and with increased specimens in our museum collection, these variables, almost without exception, could be referred to types or varieties, and the few exceptions to this statement occur in the little-studied class of pod or husk corns. Two illustrations will suffice: in New Jersey an excellent farmer there noticed a few pod ears in his crop of Blount’s prolific dent and forwarded samples to the station as novelties. The seed from these pod ears reproduced with us Blount’s prolific of perfect type and pod corn of the same type of ear which furnished the seed, and no variables from the two types noted. From the crossing of pod corn with sweet corn a new variety of sweet corn was produced, of a distinct type and esteemed by us a novelty in every respect, the cob being fusiform, the kernels horse tooth and much wrin- kled, the stalk very small. At a later date this type appeared in our collections as the banana sugar, and was proven not to be Original with us, Darwin, in his Animals and Plants under Domestication, the New York edition of 1868, Vol. 11, p. 54, has a section entitled, “ Crossing as a direct cause of Reversion,” and says: “ But that the act of crossing in itself gives an impulse toward reversion, as shown by the reappearance of long-lost characters, has never, I believe, been hitherto proved.” His line of evidence, however, 1044 Observations on the Muskrat. [ November, is different from that here presented, and embraces a different series of observations. The lack of agricultural museums in which domesticated varie- ties of plants find representation, the general ignorance of the varieties which were grown by our predecessors, and the in gen- eral careless descriptions which occur in the writings on agricul- ture, render a study of this sort embarrassing and difficult. A careful study, however, of the figures given by the botanists of the sixteenth century and thereafter, and a careful collation of evi- dence gleaned from more recent authors on gardening, together with the fact that the appearance of new form-species of cultivated vegetables seems to date from the introduction of forms of the same species from distant regions, and the rarity of appearance of novelties which cannot be identified with some previously de- scribed type, all encourage to the belief in the correctness of the generalization that in our domesticated vegetable plants cross- fertilization shows its effect at once in the reproduction of the orm-species and varieties which are involved in the parentage of the crossed seed, and that when “ pure seed” is crossed interme- diate forms rarely occur, but the original parents in variable pro- portions. OBSERVATIONS ON THE MUSKRAT? BY AMOS W. BUTLER. HE muskrat (Fiber zibethicus Cuv.) is very abundant in most localities in Southeastern Indiana. In local distribution it varies in numbers according to the abundance of water and favor- able localities for its increase. From all that I can learn, I do not think it is less common than at the time of the early settle- ment of this region. These animals soon became acquainted with man and, from ex- perience, learned that his presence assured them a great abund- ance of food at much less labor than formerly, while, at the same time, their natural enemies decreased in numbers on account of his necessity and pleasure. In some localities, owing to the perse- _ lFor instance, the deer tongue lettuce, with lanceolate leaves, which appeared _ about 1883, is almost identical with the Lactuca folio oblongo acuto figured in Bau- hin’s Prodromas, edition of 1671, p. 60.

Inthe greater number of places, however, but little attention is paid to their destruction, and in consequence they become very tame, being found within the corporate limits of some of our larger towns. Originally they had their home in the neighborhood of natural water-courses, but with the system of State improvements which led to the building of our canals, there came, in many localities, a change in the life of the musk- rats. Upon the completion of “ The White Water Valley Canal,” in 1846, the greater number of muskrats living upon the streams along which it ran, sought this artificial water-way and there established homes, No doubt they soon realized the greater security this canal afforded them from the frequent floods and from other dangers they had formerly experienced. At the pres- ent time, along that portion of the canal in existence, but few muskrats have sought the neighboring streams whence their ancestors came. When the muskrats changed their residence to the line of the canal they made new homes in its loamy banks, similar to the ones they had deserted along the river side. They are found both in our water-power canal and in the swifer streams, most numerous where there is a good food supply and at the same time near by a quiet nook secluded from the prying eyes of some human enemy and his allies. I have noticed them to be exceedingly abundant about the estuaries of creeks whose banks are covered with a luxuriant growth of vegetation. When the canal through this part of the State was destroyed in 1866, the rats disappeared from many places where they had long found a home. Some sought the river where their ances- tors had dug their holes in times long past; others gathered into certain parts of the old canal bed which were not permitted to remain unused. One of these portions is now the property of “The Brookville and Metamora Hydraulic Company,” and is used for the purpose of supplying power to several mills along its banks. This part of the old canal is about fifteen miles long, extending from Laurel to Brookville. It is here that I have become best acquainted with this water-loving rodent. The muskrat prefers its home in banks of loam or light clay, especially when heavily covered by vegetation. It is very excep- tional that it occupies gravelly or sandy banks. Advantage has been taken of this fact by the managers of our water-way and 1046 Observations on the Muskrat. [ November, by the railroad company. Where they have constructed gravel banks and kept them free from vegetable growth, it is rarely they are bothered. Trenching the banks and filling in the trenches with gravel has proved of considerable value, while some protec- tion has been afforded by a top-dressing of coarse gravel over an old bank of loam, provided vegetation is not allowed to grow thereon. When these precautions have not been taken, great damage is done each year; the burrows of these animals are con- tinually being enlarged, and caving in, cause a leak, or undermine the railroad track, as the case may be. In early spring the greatest damage is done. With the alter- nate freezing and thawing at that time of the year, the coverings of these underground passages drop in, exposing cavities of sur- prising extent to one who does not know the amount of subter- ranean work this animal is capable of doing. It requires vigilant work of eyes and ears to prevent this caving causing great dam- age to property. The underground homes of the muskrat in the banks of the canal have each two openings. When the water is at its usual stage an opening may be found, the upper edge of which is on a level with the surface of the water; another hole. may be seen at low-water mark, the top of which is just level with the surface of the water at that stage. These holes are generally from eighteen inches to two feet apart. The pas- sages from these openings lead backward and upward in a very crooked way, as any one who has attempted to follow them up can testify. These passages end in a large gallery which is the home of the animal. From this chamber a small passage leads to the surface, ending amid a bunch of grass or weeds. By this means the gallery is ventilated. The holes at the surface are known as “air holes.” They are not always found, at least I have not in all instances observed them. In heavy ground an “air hole” is always found, while in porous ground it is as often absent as not, These underground burrows extend into the bank a distance of ten to twenty feet in a straight line, as a rule. In- stances have been noted where the depth reached was less than _ the minimum given above, but such are rare. In localities along = small streams which are subject to sudden rises, the distance attained occasionally reaches thirty feet, but in all instances the depth to which these burrows reach depends, in a great measure, s emg size and SALEN of a bank as well as upon the of hboring stream to sudden changes of level. 1885. | Observations on the Muskrat. 1047 In the abandoned parts of the old canal before referred to, the muskrat built houses for the first time in this part of the State. They were few in number, and were confined to wet tracts, the source of whose water supply was springs from the neighboring Silurian hills, or in swamps adjacent to the line of the canal. Until within the past three years no houses had been built along the water-power canal between Brookville and Laurel. Each succeeding year I noticed the erection of a few more houses, until at this time there are a dozen or more within the fifteen miles just mentioned. Within ten miles of the northern end of this artificial water-way, in the old bed of the canal, have been several houses for a number of years. Whether this house-building habit is‘caused by some of the house-building muskrats coming from up the stream, or whether, from some unknown reason, the animals of our own locality have thus taken upon themselves this much of the ways of some distant ancestor, we cannot say. That muskrats do, from force of circumstances, change their location, is a well-known fact, and such a change would perhaps be the most logical way to account for the recent house-building just mentioned. I have made careful examination of some of these houses, and herewith present some extracts from my notes on one of them which I consider typical in construction and arrangement. The examination of this house was made in January last when the ground was frozen, but the more rapid streams had little or no ice upon them. This particular house was built upon the highest part of a piece of marshy ground on a peninsula extending into a stream which passed through the marsh. The end of the pen- insula had been dug off to the level of the bottom of the stream, leaving a semicircular exposure of land. A part of the base of the house followed the configuration of the edge of this excava- tion, while the remainder of the foundation rested upon the bot- tom of the stream. In consequence of this rather more than half of the house adjoined the water. The house was composed chiefly of swamp grass, sedge, coarse weeds and mud, while fresh-water algze, small pieces of drift, a few pieces of shingles and two staves were found among the more common material. The greater part of the mud was in the lower part of the house, and _Ithink was mostly brought in attached to the roots of grass. The ground: in the neighborhood of this house was cleared of all VOL. E E x. 69 1048 Observations on the Muskrat. [ November, vegetation, even of the roots, for some distance. The house was thatched very nicely with weeds and sedge. The ground plan was oval in outline, four feet six inches wide and six feet three inches long. On the land side the house was two feet six inches high, and on the water side three feet four inches. The whole presented the appearance, in miniature, of an oblong hay rick. The inside was quite irregular. Measurements at the bottom of the chamber showed the greatest length to be twenty-two inches, the least sixteen inches, with an average width of twelve inches. The greatest height, measuring from the bottom of the stream, was one foot, Six inches from the bottom a shelf was found running from the left of the entrance and above the top of the water. This shelf was twelve inches long and eight inches wide, and ranged from six to eight inches in height. It was arched over very neatly with drift and coarse weeds. At a point farthest from the center of the chamber, immediately over the shelf, was a passage leading upwards toward the side of the house. While it did not penetrate the wall, it passed through the more compact portion and enabled the inmates to obtain air. Entrance was had through a covered way from and beneath the water without to the center of the house, where it terminated in a mass of fine grass and mud, through which was a funnel-shaped opening to the interior. This house was completely destroyed; within a week after its destruction the muskrats had erected a new home upon the site of the old one. In securing material for this they had used the remains of the ruined house, and had cleared a much larger space of ground of its withered vegetation. In out- line the new house resembled the old one very much, but it was of nearly double the size of the ruined structure. There are peculiarities in the shape of many houses, but that which I have described appears typical in form and in interior arrangement of these structures in this vicinity. Some of these houses are built at a time when the water is low, and as the fall rains swell the streams the rats are compelled to ,reconstruct their buildings, raising the top above the highest level of the water. I knew a muskrat to try this plan last year. It built its house within the o banks of an ice-pond which was almost dry; as the water was turned on, late in the fall, the owner tried, by making the house higher, to keep a portion of the structure above the encroaching ter. An increase in altitude of six feet was too mych for the 1885. ] Observations on the Muskrat. 1049 industrious animal ; by the time half this height was reached he gave up the work. Occasionally instead of laying a part of the foundation out of the water, the house is begun entirely within the water. At times I have known a hollow stump, which had a lower opening beneath the water, to be used. The stump being covered over and some grass and other material placed around the base, it required close observation to recognize the framework of the structure. I have known these animals to take possession of a barrel which stood on its end in the water, and after covering it over so as to almost hide it, to give up the work and erect a dwelling without the substantial assistance such an article would afford. I find the muskrat lives, the greater part of the year, in its sinuous galleries in the banks of our streams. Each autumn new houses are built or old ones repaired, but these are only occupied when the surrounding streams are locked in a sheet of ice. At such times it is by no means uncommon to find several represen- tatives of the species living in harmony within one of these win- ter homes. I am convinced that in this vicinity one brood of muskrats is regularly brought forth each year. There are, in all probability, occasional exceptions to this rule, when perhaps two and even three broods are born. Mating takes place late in Feb- ruary or early in March, depending upon the condition of the weather, and continues about three weeks. This year these animals were first noted as mating on March roth. At this season the female utters a hoarse squeal by which the males are attracted. The period of gestation is about six weeks. In April or early May the young are brought forth; from four to six helpless and hair- less little creatures may then be found by the persevering investi- gator far within the subterranean home within a nest of grass and other soft vegetable growth. The young remain in the nest until they are about half grown, unless their home be flooded, when they often perish, but in some instances are rescued by the mother. Mr. E. R. Quick relates one instance when, during a flood July 3d, 1873, he saw a female muskrat swimming along in the muddy water with five young, about the size of a full-grown house rat, holding on to tufts of the mother’s hair with. their mouths, while she made her way slowly and cautiously along the Shore ; carefully she avoided all obstructions and swift water, . seeking a shelter for her precious tow. Some boyish enemy, per- 1050 | Observations on the Muskrat. [ November, ceiving the homeless family, threw a stone which struck the mother and scattered the young. The latter apparently knew nothing of diving and but little of swimming; with difficulty they gained the shore, and while seeking the protection of some reeds a part of them were caught. I have never found the young caring for themselves until after the beginning of July. In Sep- tember, a few years since, a litter of young was taken from a nest in the canal bank. They were not over one-third grown. This record I have always considered as referring to a second or per- haps a third brood, and is my only note that would indicate a plurality of broods. During the rutting seasorfthe grunts of the males answer the squealing of the females, the noise of scuffles between the males, the continuous splashing made by the animals in the water fill the air, in the vicinity of one of their favorite ponds, with sounds which would surprise one who was not familiar with the neigh- borhood of a muskrat’s home, on a warm night in early spring. At this time of the year they are seen during daylight more than at any other, sometimes even deigning to show their love-making to inquiring eyes. Muskrats are naturally herbivorous. They feed upon land and water plants alike, in some instances using roots, stems and fruit. ‘They are noted enemies of the “bottom” farmer. In his fields it is that corn grows most plentifully, and upon this cereal musk- rats love to feed. They eat corn at any time after it is planted, | taking the seed from the ground or the young plant from the fur- row. The greatest damage is done after the ear is well formed. “ Roasting ears ” appear to be a favorite article of food with them. From this time until the corn is gathered, nightly visits are made to the nighboring cornfield, where the stalks are cut down and ‘sometimes carried to their homes, but more frequently the juicy ear is the only part taken. At times streams near cornfields seem ‘covered with floating stalks, the result of the muskrat’s nocturnal forays. As the corn becomes hard it is frequently a difficult question for them to tell how they will get the grains off the cob as easily as formerly. They evidently master the question in some instances, for I have known them to deposit the flinty ears in a stream for two or three days until the grains become soft, when ey could be readily removed. It seems strange that an animal ing teeth al the cutting power those of the muskrat possess, _ 1885.] Observations on the Muskrat. 1051 should seek to do this, but in all probability the teeth, from con- tinued eating of vegetable food throughout the summer, become tender and are unable to cut hard grains of corn with ease. This is the case with many domestic animals in autumn when fed on corn after some months of pasture life. Muskrats are very fond of parsnips, turnips and apples. They frequent apple orchards and turnip patches, near their homes, and make use of much of the farmer's abundant crop of these articles. When snow, which had lain on the ground for some time, melted, I have observed that plats of grass near the water’s edge had been eaten bare by these animals while they were confined to such diet as they could find beneath the ice. Their food is not entirely vegetable; in winter and in early spring they subsist, in a great part, upon the flesh of river mussels. Many a winter morning have I found a number of well cleaned shells of the more delicate mussels upon the ice near swift, running water. I have never been able to satisfy my- self that this food was used by them at any other time of the year. Neither do I believe that this material was originally so used. It is very probable that owing to the scarcity of suitable vegetable food, they have been forced to include the meat of the mussel among their articles of diet; largely on account of its abundance near their watery haunts and also on account of the ease with which it is obtained. Such change of food has not Occurred in this region within historic time, perhaps, but it is evi- dent that formerly, when there were few mussels in these rivers, not so many of them were eaten. With the conditions favorable to their development produced by our canal, mussels multiplied very rapidly, and in proportion to their increase in numbers the muskrat increased his mussel-eating. Records of this are pre- Served in the banks of the canal; alternate deposits of shells, cleaned by the muskrat, and of sediment may be seen in many localities reaching to the depth of two feet below the present bed of the stream. Upon these same piles of bivalve remains the muskrat leaves the remains of most of the mussels it eats. I have never known the muskrat to eat univalve mollusks. I have identified the following shells as forming the principal part of its bivalve food in this vicinity: Anodonta plana Lea, A. decora Lea, : A. imbecillus Say, Unio luteolus Lam., U. parvus Barnes, Margari- tana rugosa Lea, and M. complanata Lea; all common in pro- portion to their comparative abundance. In some localities I 1052 Observations on the Muskrat. [ November, found the young of Unio occidens Lea, but not very common. In another locality where Unio lachrymosus Lea is the prevailing spe- cies, I found its shells forming the bulk of the refuse near musk- rat homes. In this same locality I found examples of Unio pli- catus LeS. and U. multiplicatus Lea, but they were not common. The young of heavier shells are to be found as commonly, in proportion to their abundance in the adjacent water, as are the remains of the more fragile species. I have estimated that about one-half the mollusks eaten are of the three species of Anodonta. I was surprised at the comparative abundance of the remains of Margaritana rugosa Lea in these piles of shells. This species is considered to be rather rare, but their shells are found as fre- quently there as are those of some of our more common species. From this fact I think the muskrat prefers the flesh of this spe- cies to that of others which might be more easily taken. I have, at times, found examples of living Unios among these heaps of shells; whether these had been brought there by the rats, or whether they had sought, of their own accord, a dwelling place `. among the remains of their dead ancestors I cannot say. The means by which the muskrat secures the body of a mussel has been frequently discussed of late. I think, from my observations, there are three ways in which these shells are opened. With many species I notice that the foot is very slowly withdrawn within the covering when the shell is handled. When such shells are taken it is very easy for the muskrat to insert its paws or long teeth between the valves and tear them asunder. The remains of some species show evidence of the cutting power of their enemy’s teeth, the edges are broken; when this is done it would be very easy for the muskrat to find a sufficient opening to secure the animal as in the preceding instance. By those two ways the more fragile shells may be opened; the heavier species which are occa- sionally found, nicely cleaned, about the opening of the muskrat’s home, could not be opened in this manner. I have on several occasions noticed these larger mussels lying on the bank of a _ stream near a muskrat hole, and within a few days they disap- ~ peared. The only way in which I can see the muskrat could _ obtain the body of one of these larger mollusks is by leaving the animal out of the water until it becomes weak or until it dies, when = cps could be =i ona separated. Muskrats at times ; of dea s. The remains of ducks, geese, 1885.] Observations on the Muskrat, 1053 chickens, fish, and even in one instance a turtle, have been noted as forming a part of their food. The farmers of the lowlands ascribe to the muskrat a love for young ducks, but I think the greater part of their loss in this particular is referable to turtles, The muskrat is largely nocturnal in its habits. On cloudy days and occasionally late in the afternoon one may be seen, along some quiet stretch of water, seeking food or looking for its mate. It is not much at ease on land, although when pursued it moves over the ground at an ambling gait with some degree of rapidity. It is an expert at swimming and diving. Before diving it appears to inflate its lungs with air,and when it disappears remains beneath the water for some time, the course it takes being frequently traceable by rising bubbles of air, When surprised it - plunges into the water suddenly without the necessary supply of air, and is forced to come to the surface in a very short time, When frightened it generally seeks its hole, but such is not always the case. In open water it dives to a considerable depth, and I have noticed it passing through shallow water apparently running upon the bottom. Under the ice it may be noticed, at times, swimming quite close to the surface of the water. It appears disiriclined to dive in muddy water. Upon several occa- sions, when our streams have been swollen, I have attempted to make one dive by stoning it, but generally without success ; sometimes it would dive, but would almost immediately reap- pear. When our water-courses are covered with ice the muskrat has regular places of egress and ingress, such places being where, owing to swift water, ice had not formed, or where the ice along the banks of a stream had become broken. Several methods are employed to capture or to kill muskrats. Many of them are caught by means of steel traps. They are very unsuspicious and regularly become the victims of their self- assurance. A dead fall is frequently used with some effect. It is generally placed over a well-worn runway leading to a favorite feeding ground. Many muskrats are killed by means of poisoned apples or turnips which are placed in the neighborhood of their burrows. The latter plan is often tried by the farmers of our up- lands to kill these animals when they become too numerous in the ditches and smaller streams. A method used with great suc- cess by a local water-power company, in winter, is as follows: A barrel with both ends out is placed upright near the bank with 1054 Observations on the Muskrat. [ November, about half its length in the water. Upon the water inside the bar- rel is placed grass and weeds, and on this foundation the bait, gener- ally a few pieces of parsnip, is put. In a few days the animals will become familiar with this new object, and thereafter the barrel may be visited regularly. After a warm night the trapper is rea- sonably sure of finding some game in his barrel. Sometimes he will find but one or two rats, but more frequently he will catch from three to six, and on one occasion I have known ten rats to be taken in one barrel ina single night. At mating time if a female be caught several males will be taken prisoners in the same barrel in their efforts to become her company. When a rat gets into the barrel it is impossible, owing to the depth of the water, for it to stand upon its hinder limbs to cut a hole in the staves above water line, and at the same time impossible for it to get out at the top of the barrel. When several are taken the same night a fight generally ensues, resulting in the death of all of the cap- tives either by the sharp teeth of their companions or by drown- ing. I have known instances where several of these rats had been captured and killed, but the trapper did not visit his traps for some time; upon his arrival, however, he found but a few heads and bones to tell of the tragedy that had been enacted and of the feast which the other muskrats had when the water receded enough for them to enter and leave the barrel. This habit is not uncommon when more acceptable food is scarce. Last spring a _ muskrat was caught in a steel trap; when the trapper went to his trap next morning he found another rat eating the dead one; upon examination it was found the entire right shoulder had been eaten off. Spears are rarely used, but they are sometimes brought into service when the streams are ice bound to kill the inhabitants of a winter house. Many muskrats are shot in early spring when the ice breaks up. Of the enemies of the muskrat man ranks first, and next to him the dog. Hawks and owls of the larger species, foxes and minks are all very destructive to this animal. The mink is per- haps it greatest natural enemy, but fortunately for it minks are rare. The remains of muskrats have, on several occasions, been found in the stomachs of large catfish, but the flavor of the food had. been so thoroughly imparted to the meat of the fish that it as unfit to eat. The muskrat is at times very ferocious. When by dogs or man it frequently shows fight, and if pressed me to dor much execution with its sharp teeth.

On a warm quiet afternoon they appear to enjoy a sunning in some secluded spot. Their gambols in the water, of a quiet evening, remind me much of the playing of kittens. They may be seen at times, of a moonlight night, chasing each other over some sand bar near their watery home. On the whole a study of their enjoyments is very unsatisfactory, and much of our knowledge of the life his- tory of these animals will be but slowly acquired. THE PROBLEM OF THE SOARING BIRD. BY I. LANCASTER. t is now more than two years since I first made known the results of investigations on the methods of flight of the great soaring birds, carried on at intervals since 1850. The whooping cranes of the Northwest, performing their migrations on motion- less wings, had at that early date fixed my attention, and my times of leisure down to 1876 were devoted to ransacking the Scientific and literary world and to observing the birds in the act whenever it was possible to do so, that I might get an explana- tion of the phenomenon of more substantial character than mere guess-work. Plenty of assumed solutions were found scattered about. Such theologians as I consulted were confident that the question had reached its lowest terms when it was said that “ God had created the birds to fly.” Common-sense folks rejected the idea of fixed wings and held to a slow flapping that could not be seen, while the scientists were confident of upward slant- ing currents of air and various atmospheric disturbances which produced the result. Accounts of travelers as to the facts were hopelessly confused, with a single exception, that of Charles Darwin in his Naturalist’s Voyage around the World. His solu- tion of the matter, that of the surging head, was given provis- ionally, I was not prepared to deny aay of the solutions given and not More ready to admit them, being conscious of very much igno- rance of the entire matter. Meanwhile my interest in the sub- ject, constantly increasing, had, in 1876, overshadowed all others, and being disengaged from business, I devoted the ensuing five 1056 The Problem of the Soaring Bird. [ November, years to the birds on the Gulf coast of South Florida, where the soaring varieties were found in abundance, fully intending to un- ravel the case before leaving it. The task was a hard one, and the final solution was found in a totally unexpected direction, The predominant feeling I have since experienced in regard to it is one of surprise—surprise that in this ceaselessly active age mechanical possibilities of the most important character could exist in the atmospheric spaces all about us, with many of the largest species of existing birds putting them in daily practice before our eyes, and we still remaining completely ignorant of them! I propose in this paper to present, first, a few of the most significant facts exhibited by the soaring birds; next, to offer an explanation of the phenomenon; and finally, to examine the bearing of what has been said on the problem of artificial air- navigation. I mean by a “soaring bird” one which habitually travels the air on motionless wings. All birds flap their pinions at times, and many of the smaller kinds, such as rooks, kestrels, crows and gulls can maintain flight on fixed wings when the conditions are favorable. But I would never think of observing them for les- sons in soaring. They are too light to average the inequalities in the air current, and there are frequently long intervals of active wings before the fixed conditions occur. The soaring varieties are at it all the time. The frigate birds live in the air night and day for a week at a time without touching a roost. Their con- geners, the buzzards, spend the day in the same style, The vari- ous cranes common to the coast often spend hours resting in the air, while the gannet is an admirable soaring bird with a heavy body and relatively small expanse of wings. When I speak of “ fixed” or “ motionless ” wings the meaning is that no muscular power is used to either overcome weight or air resistance. It is not meant that the pinions are absolutely rigid, like a board, for they are moved to accomplish change both in shape and position. But they do precisely resemble a board so far as the exertion of motive power is concerned. For instance, _ if abird floats in a wind of unvarying velocity over any fixed _ point on the earth, then if a board of the same shape and size and weight were put in its place, it would remain there just as the bird does, as long as the conditions were unchanged. If the bird y changed the shape or position of its surfaces so as to ver- 1885. | The Problem of the Soaring Bird. 1057 tically ascend indefinitely, the board would also ascend in the same way were it to be changed in a similar manner. This is seen in the performances of what I have termed “ effigies.’ They were surfaces of veneer or cardboard fastened to a frame and balanced by a weighted pendant. They would simulate the actions of “soaring” perfectly. I have made num- bers of them. They would leave the hand and travel against the wind for as much as 500 yards, remaining up for fifteen minutes. They had no ability to automatically balance themselves in un- steady currents of air, but they were good illustrations of “ soar- ing.” The first thing to be definitely ascertained was whether the wings of the soaring birds were in fact as motionless as they seemed. To determine this point demanded close inspection, and although the creatures were not fearful of man in that remote country, they preferred a distance of thirty to forty feet away. The captive bird was useless for any critical test. ’Tis true that a bird ten feet in alar dimensions, resting horizontally above one’s head thirty feet away, with the ‘clear sky as a background, could be pretty well examined; still a closer position was not only desirable but imperative, and a resort was had to the arts of mimicry with entire success. Procuring a few square yards of thin muslin fabric sufficient to completely envelope my person, it was covered with paint of the green and brown shades so as to resemble the tree tops of localities in the vicinity of either the breeding places or the roosts of the soaring birds, and barring the unpleasant sensation one has when engaged in the arts of gross deception, I had everything pretty much my own way. Some trouble was experienced in striking the happy mean of scaring the great creatures enough to keep them from lighting on my face, and still not frighten them away, as they were totally oblivi- _Ous of my presence. Wing movements could now be studied in every conceivable position at leisure, endwise, sidewise, from above, from beneath, and at every sort of obliquity. The conclu- sions of observations made from the ground at thirty feet distance were confirmed from the tree-top stations at all distances, from twelve inches upwards. In the first Florida year, observations were made with good results about 150 times, during which all the varieties of soaring birds of 100 miles of coast line were viewed. The trees of the country are short and stunted, and 1058 Lhe Problem of the Soaring Bird. [ November, easily climbed, and a little search was rewarded by the discovery of thick sturdy tops in which a secure lodgment could be had. The birds abounded in prodigious numbers, thousands occupying a single roosting ground. Not only was it seen that there was no motion of the wing as a whole, but that there was none of the individual feathers. There was no tremor, no slow nor fast waving ; the entire bird moved when the wing did. When the wing was flapped there was no doubt about it, and the flapping could be seen as far almost as the bird was visible. Both the “soaring” and flapping were discoverable when they occurred beyond any doubt whatever. To determine horizontality of the sea breezes of the coast, a radial arm, feathered and balanced level, was used. It is evident that somewhere in the interior of the peninsula there must be an upward trend of the meeting winds from the Atlantic and Gulf, but there is none discovera- ble on the western coast. The wind, twenty-five feet above tide, moves uniformly on level lines, and ten feet above the forest tree tops no upward flow can be found. The lantern of Egmont light, 150 feet high, at the entrance of Tampa bay, was frequently used for these atmospheric observations. There is a wide range in the relation between weight of bird and wing surface in the different species. It varies from less than one, to more than two feet for each pound weight. Uniformly the longer the wing to a given weight the greater the power of translation possessed by the bird, the man-of-war hawks in this respect surpassing all others. Wide, short wings were coupled with heavy bodies, as in the gannets, and these exhibited slower but steadier flight. The heavier the bird the steadier and easier seemed its movements, and a hungry vulture, which was very shaky in the breeze, could ride serenely when gorged with carrion. The only peculiarities discoverable in the atmospheric condi- tion required for soaring, was that the wind in all cases should move against the bird. The maximum velocity of this meeting of bird and air is unknown to me. I have timed the flight of. frigate birds through calm air on fixed wings at 100 miles per hour, and their velocity seems to depend on their wishes more than on any limitation of the powers of translation. The mini- mum speed, however, can be approximated. For the frigate bird . = it is about two miles per hour, three for the buzzards and five for _ the gannets. The heavier the bird the greater is the minimum | _ velocity required, and a gorged vulture cannot range itself with flock of hungry ones, which are sporting in their minimum, repeatedly flapping its > r its wings. (Zo be continued.) 1885.] The Relations of Mind and Matter, 1059 THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. ( Continued from p. 953, October number.) VI. THe MENTAL ORGANISM. WE have now to consider a question of very great importance, that of the relations of the mind and its energies to the universe of matter and energy without. A review of the condi- tions of mental energy leads to conclusions of much significance. These, however, can only be given very briefly, but we will en- deavor to point out their leading features and show the direction in which they tend and the remote possibilities of mental devel- opment which they indicate, In the lowest animals, in which psychical powers are yet very feebly developed, if they exist at all, the inflowing energy makes its way at once to the muscular or contractile regions, and motion takes place in response. The action of external nature upon the body is immediately followed by a reaction of the body upon ex- ternal nature. Where this action and reaction are in harmony, the body is a well-adapted reflex organism. As already said, however, with every new condition in the action the reaction becomes general, and new special adaptation is only slowly gained. And where there exists the rudiment of a psychical organism €very sensory action of a new character probably always disturbs its conditions, yields a conscious sensation and affects its motor relations. By a long continuance of this process the mental Organism becomes greatly developed. Of the external energies which crowd into the body during this increase in sensory and mental powers a constantly smaller percentage goes directly to the muscles, and a larger percentage to the mind, into which they enter as organizing or otherwise affecting agencies. Thus the energies which are checked in their flow through the body are never lost, but are employed in building up a reservoir of ener- gies within. Instead of producing an immediate and direct reac- tion upon outer nature, they now produce a retarded and indirect reaction. The condition of affairs is vitally changed by this new Condition of the organism. The body is at first an instrument of €xternal nature alone. It is set in motion by the energies of cer- tain external substances, and exerts energy on other external sub- stances, But in its advanced condition the force of the external 1060 The Relations of Mind and Matter. (November, energies is mainly exerted upon a fixed region of the organism, in which they become definitely centered and organized. And this reservoir of energies in its turn reacts upon outer nature, Instead of a single agent of action, with the body for its instru- ment, we have now two agents, an internal and an external one, with the body for their instrument. The nervous organism serves as the channel of intercommunication between these two active agents. And the high-atomed chemical molecules of the nerve cells or terminations, whether those of the outer surface, the muscles or the cerebrum, serve as sources of intermediate energy, which add to the vigor of the slight motor impulses from without or from within. In this view the mind is as little a necessary constituent part of the body as is outer nature. The body can perform its ordinary duties without the mind or its organ, and needs it only for its extraordinary duties. In its primary relation this new condition of the organism only acts as a check on the rapidity of motor reaction. The mental affections retain their original form, and their reaction, when it takes place, will be of the same character as the immediate reac- tion would have been. But the mental organism soon begins to act as an independent agent. From the conditions impressed on it, new conditions are produced. There is an internal reaction and new combination of the mental energies. Memories com- bine to form thoughts or ideas, and motor relations are gained within the mind which have no counterpart without. These, in their turn, react on outer nature and yield peculiar results, nO longer in consonance with external conditions. The microcosm without has built up a microcosm within, with powers and condi- tions of its own, and the body now becomes the intermedium be- tween two independent and dissimilar acting agents. These may act only within themselves, or they may act upon each other through the medium of the body, each producing special modifi- cations in the condition of the other. _ These general considerations lead to more special ones. What is the character of the impressions produced by external energy ` upon the mental organism? These external energies are yielded __ by the substances of external nature, and in some way represe? . the conditions of these substances. As such they enter the body l impress the mind. Though all sensations may be conv the nerve fibers as vibratory impulses, yet there must be some s 1885.| The Relations of Mind and Matter. 1061 difference in the character of these vibrations with every new kind of sensation, since the mind receives a peculiar impression from every peculiar sensory impulse. The memories thus implanted in the mind represent to us the conditions which exist without us. This tepresentation very possibly may not be an exact one. Possibly it is only analogically similar. But it is all we know of external nature, and although each impression may not truly reproduce the condition from which it arose, there can be no doubt that the relations between these impressions are correct. The picture must be correct as an analogical reproduction if not as an actual one. It must be borne in mind also that the impressions received indicate the motor conditions of external substances, and that they become motor conditions of the psychical substance, so that their exactness of representation may be much closer than is usually surmised. The mental organism thus acts as a mirror, in which the uni- verse becomes more or less fully reflected. Its memories are reproductions, more or less exact, of external conditions, and it exists as, in a partial. measure, a counterpart of external nature. But it is much more than this. Its powers are not confined to the reception and storage of external energy and the reflective reproduction of the forms and forces which emitted these ener- gies, but it has a reorganizing power of its own. Its energies Combine and produce new conditions, which may or may not have a counterpart in external nature. If these new productions are the outcome of reason they may represent conditions or forces in nature which are not apparent to our senses, as, for in- stance, the attraction of gravitation, or the vibrations of heat and light. If they are the outcome of imagination they may repre- sent conditions which do not exist in nature and which are new Creations of the mind. ; The vision of a cathedral, for example, gives us a mental im- Pression which becomes persistent. The mind has henceforth among its stores the image or representation of the external com- pound of matter which we call cathedral. A picture or a descrip- tion of a cathedral may produce the same image. Close observa- tion gives minute knowledge of the constituent parts of this edifice, and reasoning yields what the senses cannot convey, a conception of the architectural principles involved and of the forces at work in binding the parts of this structure together 1062 The Relations of Mind and Matter. _[November, down to its very chemical atoms. Thus by sensation and reason- ing the mind gains a very minute and complete image of the edifice, which it may review in part or in the whole, as it will. The building seems to be erected in the mind, by the ease with which it can be mentally taken apart and put together, and each of its parts called up as a separate and distinct image. But the mental powers can go much further than this. They can make different combinations of the separate parts of such an edifice and work out different results of the principles of archi- tecture, and thus produce a compound not existent in external nature. This is the work of the imaginative or constructive faculty. In both these cases we seem to have but varied combi- nations of the mental images or energies. But the new form of building thus mentally constructed need not be confined to the mind. It can be erected in outer nature by the aid of the hands, or of other minds and hands. Thus as the mind mirrors exter- nal nature, the external may be made to mirror the mind, After beholding the cathedral there exists an image in the mind corre- sponding to a condition of external nature. After erecting the new edifice there exists a form in external nature corresponding to an image or condition of the mind. Mind and nature act and react upon, and each molds and modifies the other. The illustra- tion here given might be endlessly paralleled, since it represents the general character of all the mental operations, Evidently, then, the process of development is two-fold. The mind is being developed under influences derived from without, and the outer world under influences derived from within the body- The mind and the universe are becoming counterparts of each other, the one in external matter, the other in that unknown sub- stance which is the basis of mind. Thus every mind is becoming a partial counterpart of the universe. At first this mirroring of the universe is very slight and imperfect. The mirror is of minute surface and very clouded in texture. But with the growth of knowledge it widens and grows clearer, and a continually greater breadth of the universe is reflected within it. If devel- oped to its utmost conceivable extent, it might take in the whole universe and constitute a reproduction, in its special and localized conditions, of all the conditions existing in the broad range of _ external nature. Like the monads of Leibnitz, each of which was conceived to mirror all others, and each from its own special 1885.] The Relations of Mind and Matter. 1063 point of view, each mind might come to mirror all things, physi- cal or mental, and each from its own special point of reflection. Such a duplication of the conditions of the universe would be the necessary result of the infinite Rees of the relations of the mind of man to external nature. | The mode in which the thought constituents of the eid pre- sent themselves to consciousness strongly point to the above con~» clusion. We seem to become conscious of the existence of a caunterpart, within our minds, of the universe, so far as we have come into rapport with it. There lie the forms surrounding us, the trees, houses, plains, mountains, &c., down to their smallest details, and each in its appropriate relation, alike of force and of position, to the others, With extended knowledge we gaina mental picture of the whole earth, with its diversity-of natural Scenery, its continents and oceans, its empires, cities and inhabi- tants, human and brute. The geological conditions of its surface are similarly apparent to us, and the deeper regions, so far as we are aware of their conditions. The intermotions and connecting forces and principles of these objects also form part of the men- tal reproduction.. None of us have ever seen the whole of this picture. It has been mainly.conveyed to our minds as a reflec- tion from images present to other minds. Yet if we wish to see the earth we have but to look into the depths of our minds, and there we behold it, with all its parts arranged in their due order and telation. The mental universe of man is far more extensive than this. It stretches downward to include the minutest forms. We can even perceive the excessively minute atoms going through their endless.dance, and the vibrations of the ether as radiations. of light and heat run swiftly through it. It stretches upward to include the mightiest forms, the revolving planets and shining Suns, each with its peculiar motions and attractive vigor. To see all this we do not need to look around us. We have but to look into our minds, into which it has entered and organized itself. The whole or a part may be seen at will, often falsely perhaps, from imperfect conceptions, but there lies our visible universe as it appears to our eyes, has arisen through the exercise of our rea- Son, ar has come to us at second hand from the eyes and minds of others, - We may, for instance, call up the memory of atree.

And it is remarkable how new impres- sions of an object annex themselves to those previously received, and thus fill out the original image. Our first idea of the human body is a mere outline. To this are gradually added impressions of its distinctive surface parts, its internal organs, its tissues, cir- culation, &c., its motions, and its general principles of formation and physiological functions. Each of these falls into its proper relation with the others, building up a full ideal image of the body. But this image retains the character of a manikin. It can be taken apart at will, and each part considered separately from the rest. This essential peculiarity pertains to all ideal concep- tions. They have none of the necessary coherence of natural organisms. The conception never becomes an indissoluble men- tal image. It may be anatomized, as the body may, but without need of the slow process of dissection. As to the part taken by the different senses in building up this mental picture there are important distinctions. Some yield us impressions of form and some of quality. The senses of smell, taste and hearing simply advise us of certain qualities or condi- tions of external things. Touch and sight also yield impressions of quality, but of form as well. They acquaint us with the space extension of objects, and also with their space relations and motions. It appears strange how the mind can gain a permanent record of the motions of one body in relation to others. We can only comprehend it as a record of form relations with time extension, the sensory impression of a very rapidly succeeding series of pictures on the mind, in each of which the relation ot position of objects is changed. On recalling to consciousness this series of pictures the idea of movement must arise with it, precisely as occurs in the optical toy where a series of gradually pictures are blended by rapid succession on a moving disk, and the figures made to appear as if in actual motion. The impression of a musical air on the mind is probably of analogous character to the above, a time succession of differing sensations. The reason has much to do with the correctness of our impres- sions of form. The eye receives its picture as a flat one, and it _ must t affect the mind as such.

If we continue to view the mind as a substantial organism, and its conditions as due to the motor relations of the parts of this organism, the mode of impression of a formal image on it may bear some relation to photography. It may seem inexplicable that the same nerve fiber in convey- ing currents of energy can yield such different impressions as these currents vary in their source. It might be argued that such currents could only differ in degree and not in kind. And yet the eye receives its pictures from currents of energy conveyed through a single medium, that of the vibrating ether. The varia- tions in light and shade, color, &c., are due to variations in the conditions of this energy, and similar variations may exist in the nerve current. As an object photographs itself, through the effects of these variations in the energy of light, on a sensitive tablet, so the retinal picture of such an object, through similar variations in the energy of the nerve current, may produce an analogous effect on the sensitive mental tablet. The idea of photography, of course, is offered but as an illus- tration of a sensitiveness of inorganic substance which imitates, though remotely, that of the mind. In the instantaneous pho- tography of recent years plates are made of such exquisite sen- Sitiveness as to take a good picture in a very minute fraction of a second. While these plates are kept from the light no change is produced in them. The instant the light falls upon them an exact surface copy of the object from which it emanates is produced on the sensitive plate. And this picture becomes a permanent condition of the plate. Some change has been pro- duced in its motor or chemical organization, and the picture remains an indissoluble characteristic of its subsequent organiza- tion! The parallel this presents to the mind, viewed as a sensi- 1In illustration of the sensitiveness of material surfaces we may quote from Pro- of the wafer comes into view, and this may be done again and again. Nay, — more, if the polished metal be carefully put aside, and be so kept for many months 1066 The Relations of Mind and Matter. _[November, tive organism, is strikingly complete. We may, as an analogy, view this organism as having a delicately sensitive surface, which remains unaffected while it is kept from the influence of the nerve current, like the photographic plate when kept from the light. But the instant the energy of this current touches it a pictured image is produced which closely represents the object which instigated the nerve current. -And this picture becomes a per- manent condition of the mind. It indicates a fixed change in its motor organization. In this respect, however, the mind repre- sents a photographic plate of extraordinary sensitiveness, one in which we might imagine that each picture sinks below the sur- face, or a new sensitive surface is immediately formed over it. We may pursue this analogy of the organism of the mind to conceivable photographic conditions somewhat further, and reach other interesting conclusions. In .this connection the relations which our mental impressions bear to each other form an impor- tant subject of. inquiry. These relations are of two kinds, one of similarity, either direct or analogous, and the other of contiguity in time of reception. Each new impression seems to’ connect itself with all preceding similar impressions in such a manner that consciousness of the one tends to recall the other to conscious- ness, this effect being the more marked the greater the As intimate a relation exists between i i ived together, although they may be very unlike. Their’ connection in time serves as a link of combination. They elbow each other in the mind, as it were, . _ These are the two distinguishing features of remembrance, and seem to point to two distinct conditions under which the mind re- tains its images.

It is as if, as above said, the mental organism at each period presented a clear surface for the photographing of impressions, which was immediately covered by a new-formed surface. In this view the mind seems to present itself as an unlimited series of overlapping Jaminz, on each of which is photographed the thoughts and events of one period of life, while the touching of any special lamina by consciousness calls up to the mental vision all the contiguous impressions on that lamina. And the fixed hereditary constitution of the mind may be a deep-laid foundation, overlaid by these succeeding formations and far beneath the reach of consciousness, yet exercising a vigorous influence over the later developmental processes of the-organism. Another point neces- sary to mention is that physical impressions and mental concep- tions appear to affect the mind in the same manner, so that it becomes sometimes difficult to distinguish between a sensation, a memory or an idea. In states of hallucination no line of demar- kation remains, and at any time the principal distinction seems that of vividness. The mind apparently retains its images in but a single mode. ; The relation of similarity adds another structural feature to this conception of the mind. If we see a fine view to-day it may call up to our mental vision a somewhat similar one seen ten or twenty years ago. We have reason to believe that identical im- pressions flow together and strengthen their resultant, until the mind may very feebly respond to an incessant repetition of the same image. The motor conditions of the mind are so in har- mony with the sensation that it produces a hardly appreciable disturbance. This would indicate that identical impressions affect a fixed locality in the mental organism, and the same may be the case, in a less exact degree, with all similar impressions. In such a case the relation would not be one of surface contiguity, but of vertical contiguity, the localized impression being in close rela- tion of position to all similar ones lying below it in the depths of the organism. All this, of course, is pure hypothesis, yet it is of interest in connection with the phenomena of the association of ideas, if we consider the mental conditions to be the organizing relations of a substantial organism. Yet one further resultant of this analogical conception of the mind may not be amiss. The sinking of an impression below the sensitive surface of the mind 1068 The Relations of Mind and Matter. [November, might have some relation to the frequent difficulty of recalling an old memory, and the general disappearance of memories from the grasp of consciousness, until recalled by some association. For consciousness may be looked upon as a superficial affection of the mental organism, aroused only when this surface is acted upon by cerebral energy. But present sensations might be able to connect themselves with old memories in the manner just described. And in so doing they might rouse a whole sheet of memories, spread over some deep mental lamina. The energy which produces a surface consciousness, through rapport between the mind and the cerebrum, might through this rapport of the mental laminz make its way to deeper regions, and awake long dormant impressions of the mind. The hypothetical idea of the constitution and development of the mental organism just given, while perhaps very remotely analogous to the reality, yet answers to the conditions of sensory reception and memory with sufficient exactness to be worthy of a clearer delineation. In this view, then, each man derives hered- itarily a firmly-constituted germ of the mental organism, destitute of ancestral experiences, yet, like every part of the body, pos- sessed of its innate habits, capable of exercising more or less control over all subsequent mental activities, and also limiting by its conditions the degree and direction of the subsequent devel- opment. This is the hereditary mind, the granite rock basis of its future formation. It has no power in itself to develop beyond this. All the other organs of the body may fully unfold from their innate forces while the mind remains in the germ. Its development is a purely individual process, and the results are not transmissible to offspring. Still considering it as a substantial organism we seem to behold layer after layer of new substance laid down upon it, as strata are laid upon the granite basis of the geologic formation, and taking form from the form of this basic organism. Each of these lamina is delicately sensitive to the impress of external energy, and be- comes covered with a series of pictured images, the fossils of the = memory. With the formation of each new lamina all preceding __ ones are buried below the immediate contact of energy and the direct reach of consciousness, But as the impressed images on ach lamina are in horizontal contact with each other, so each new à seems to be drawn to a locality of the organism which 1885.] The Relations of Mind and Matter. 1069 has been the seat of similar impressions. It is as if, in seeking entrance to the mind, it found its easiest channel at the point where impressions of some degree of similarity had already en- tered. Thus impressions of similar character become vertically in contact or in close contiguity. This idea certainly offers some explanation of the phenomena of recollection, or the recall of memories. Consciousness is a resultant of the immediate relations of the cerebrum with the surface conditions of the mental organism. It has little or no penetrative power in itself. To receive an impression on a fixed mental locality does not of itself cause disturbance of the impres- sions which may lie below that locality. But when an impression is added to a vertical series of similar impressions, consciousness seems to make its way downward and to arouse the whole or any Specially harmonious part of the series. And on thus reaching any mental lamina it may spread itself widely over that lamina and arouse to our attention a broad sheet of its impressions, Such seems the character of conscious association. No memory is recalled except through direct or indirect links of association with some present phase of surface activity. And no memory remote in time reappears until consciousness first establishes a rapport between some present impress or idea and a somewhat similar one received at that period of time. The conditions thus impressed on the mental organism from without never remain separate conceptions, like the successive Pictures in an album. They combine with each other and es- tablish relations resembling those that exist between the originals. All we perceive are forms, qualities or conditions, and motions. Any deeper knowledge of nature must be attained through the innate operations of the mind. The received motor conditions do not lie passive in the mind, but spread under the influence of Consciousness, or the energy which consciousness represents. They gradually exercise their native affinities and establish con- nections and relations similar to those which they possessed externally. The forces and principles which exist between ex- ternal forms and conditions become evident between their mental counterparts as memories combine into ideas, and these forces and principles become in their turn objects of conscious concep- tion. The universe tends to repeat itself fully in the mind. But mental activity does not stop here. Forms and forces also 1070 The Relations of Mind and Matter. [ November, enter into relations which might possibly exist in outer nature, but which have never existed. Thus the mind erects an ideal world of its own, which it has the power partly to reproduce ex- ternally.. This power of ideal formation is practically unlimited. The world within to some extent cuts loose from the world with- out, grows beyond immediate dependence upon it, reproduces the possible as well as the actual, becomes a self-centered and special- ized compound of energies, and reacts as a modifying agent on that external world which has so long and so powerfully acted upon it. | As already said, the mind as a developed organism is not, like the remainder of the body structure, transmitted to offspring as a constituent feature of the germ. It must grow up in each indi- vidual anew. The most fully developed cerebrum has no power in itself to unfold the mind beyond its embryo stage, the seed of psychic existence which is derived from a long line of ancestors. ‘The fundamental psychic conditions of our ancestors persist in our minds, not as experiences, but as strongly influencing tenden- cies. We cannot relegate these innate tendencies to any personal experiences, but they have the force of a large body of expe- riences. They form the fundamental state of ‘our mental or- ganism, over which are laid all its more individual states. They are a collocation of tendencies, inclinations, attributes, emotional strains, &c., which compose the original stuff of the psychic germ, the framework upon which all its later material is molded. From this original strain and the variations produced in itby subsequent experiences, proceeds our mental character, which is thus a com- bination of heredity and experience. Our own course of thought adds nothing to it, but the shades of change in mental character ‘which are produced during our life may be transmitted to our offspring, and thus evolution take place in the hereditary basis of mind. This mental character forms our great moving power. It may occasionally be overcome by vigorously concentrated thoughts, yet it exercises control over the action’ of nearly all ‘our mental motive powers, and forms the great restraining agent _ Of the mind, the concentrated wisdom of a thousand generations: -But for it our actions might be very erratic, without a rudder to _ guide the movements of our headstrong and vagrant thoughts. 5 _ Judgment is not a passive, but an active quality.

The actions we perform, the resolutions we take, are greatly subordinated to this compound of influences, They exerta force which we call will. In emo- tional states, on the contrary, when a few thoughts, or a single thought, perhaps, are abnormally active and the general sum of thoughts driven deep into unconsciousness, the will is differently conditioned. Vigorous and often abnormal action takes place in response to these active mental energies, and in spite of a dull protest from the nearly banished judgment. The active thought takes the bit between its teeth and runs away with us. The indi: cations are that each conscious thought becomes an agent of control in accordance with its degree of activity, that the force resultant of all the thought activities present to. consciousness at any one period constitutes the will-power, and that the action of this will be normal or abnormal i in accordance with the ae or the narrowness of the agencies active in it. As for the control of the body by the mind, it seems almost as if the latter possessed an exact transcript of the muscular appa- ratus of the former. Desire to move a certain limb is accom- panied by thought of that limb. Does a representation of the desired motion take place in the mind ere action is exerted on the motor nerves? Is there conscious excitation of a region of the mind which is in direct cerebral connection with the limb? We do not think of the muscles, but of the limb to be moved. As the mind contains a conscious transcript of external nature, does it also contain a complete transcript of the body, and does its self. -performance of the action desired, upon its image of the phys- ical frame, call into activity that region of the mental organism which communicates with the desired muscle? If every portion of the body is in direct connection with a fixed portion of the cerebrum, as is probably the case, then each portion of the mental organism may possess a similar connection, and to think of a limb is to rouse that part of this organism which is in immediate Motor connection with the muscles governing that limb. Much of this connection must be hereditary, and its action a mentally reflex activity. Butcontrol of the body by the mind is in con siderable part acquired. It seems almost as if the mind sought out the body, and only gradually completed its picture of it, or brought itself into complete motor relations with it. - 1072 The Relations of Mind and Matter, (November, The usually entertained idea that our mental picture of nature is only analogically correct, which has by some writers been car- ried to such an extreme as to deny that the external world exists at all, but that the mind and its images constitute the universe, calls for some attention here. The extreme view may be at once dismissed as not consistent with what we know of the laws of energy, which forbids evolutionary changes in a concrete or- ganism except under the influence of energies received from without. And a strong argument may be brought in favor ot the view that our conceptions of the external are not illusory, but that the image received by the mind is a close reproduction of the conditions actually existing in external nature. Bodies’ are composed of matter, but it is matter molded by force and energy, and all form and quality are due to the inter- relations of this energy. Color is due to a special action which is exerted upon the waves of light ; sound to an action upon the molecules of the air. Colors and sounds, therefore, while not belonging to the body which seems to emit them, indicate special conditions or qualities of that body. By the study of these special emissions of energy we arrive at deeper conceptions of the true character of the body. Our first conception of any object is very crude and inexact. Exactitude can only be gained by a close scientific study of all these special characteristics and influ- ences of the object. Our senses do not advise us of the real character of matter, but only of its combinations and their proper- ties. Nor are we aware of absolute, but only of relative condi- tions. Our body, with its conditions, is the standard by which the universe is ordinarily measured. If our body was colder what we now call cold would become warmth, If it was firmer hardness would become softness. If it was larger largeness would become smallness, But science is rapidly ceasing to make the body the test of nature, and has made some steps from the relative towards the absolute. It declares that a certain tempera- ture arises from a certain vigor of vibration, a certain color from a fixed rapidity of vibration, that degrees of hardness arise from _ fixed degrees of resistance in bodies, &c. It is true that these = results are expressed in terms of space and time, and space and =~ time extension must remain to us relative conceptions. Yet nothing else need be relative. If the apparent dimensions of s are truly related to our conception of space and the dura- 1885.] The Relations of Mind and Matter. 1073 tion of events to our conception of time, they are true to this . extent, and within this limitation we may arrive at correct con- ceptions of existence, Objects emit energies. These energies are external expressions of the conditions of the object emitting them. So they are acted upon by energies which they partly repel, and which are modified by their momentary connection with the object. On the other hand the energies which penetrate the object from outside act to modify its conditions. In other words, all energies exert a power of leverage. The energies emitted by any object on flowing into another forcibly impress some of their peculiar characteristics upon it. The receiving body is brought into a certain con- formity of condition with the emitting body. This leverage is in constant operation, and every body is seeking to change every other body within the range of its influence into an image of itself. These emitted energies vary. Some are general, like those of heat. Others are characteristic. The degree of leverage exerted depends upon the degree of special modification in the emitted energies. Through this assimilating influence, and the counter influence of opposing energies, and of innate forces, bodies are organized. But the influence produced by this leverage depends upon the mobility of the body acted upon. Some are rigidly centralized and vigorously resist change. Others readily yield. Some are peculiarly mobile, and may vary in condition under every impress of special energy from without, assuming some degree of simi- larity to the emitting bodies. In this mobility, or sensitiveness, the mental organism impresses us as far beyond any other condi- tion of substance in nature, and therefore as peculiarly adapted to respond and vary into conditions of organization in conformity with those of the bodies acting upon it. And its power of re- taining these impressions is so excessive that it is capable of receiving them in countless numbers, with little or no obliteration of those formerly received. But this conception of the leverage of energies upon the mind and its faint resistance, leads directly to the conclusion that the Mental organism is becoming, in an exact sense, a reproduced Copy of external nature. The conditions of all bodies are merely arrangements of matter under the influence of innate energies. The energy is the essential constituent of condition, the matter only its inessential basis. Any substance which accepts these 1074 The Relations of Mind and Matter. [ November, modes of energy necessarily assumes similar conditions. The combination of energy without produces an equivalent combina- tion of energy within, and the mind takes on characteristics of organization resembling those of the bodies acting upon it, pre- cisely as the photographic plate may be said to assume surface characteristics resembling those of the bodies to whose emitted ‘energies it has been exposed. And this modifying influence is not exerted solely during the life of the individual, but is also an element in the hereditary conditions of the organism. It has been exerted throughout the ‘whole phylogenetic development of the individual. The leverage ‘of external energy is not exerted upon each mind separately to the production of changes in an original rigid substratum, but this substratum itself has been organized under the influence of such energies, from its origin in the earliest germ of psychical existence, becoming steadily more complex under the incessant play upon it of the energies of the universe. It seems to follow as a necessary consequence that our conceptions of nature must ‘represent actual conditions, and that the whole mental organism, down to its: inmost center, has been molded by external nature, and is an exact reproduction of nature to the extent that it has ‘come into contact with it. But this only represents the mental conditions in part. The mind has some directive control of its own forces. These inter- ‘act, combination of mental conditions takes place, and results ‘arise which have no counterpart in external nature. These, in ‘their turn, exert a leverage on external substance, and forms are produced which exactly represent the ideal — of the mind. The mind molds nature into its own image?

Similar combinations take place in objects, and the ener- gies received from without combine with those within to produce: new conditions. If the mind has a substantial basis it must con- form, in every respect, to the principles which display themselves in external compounds of substance. Yet in this respect the mind seems to be -peculiarly active. The objects of the outer world consist of a dense aggregate of matter affected by a limited volume of energy. As all change is due to the interaction of this energy, external objects vary but slowly and slightly, slug- gishly resisting its action. In the case of the mind we may con- ceive its substance to be reduced to a minimum and its energy enhanced to a maximum. Thus its mobility is extreme, its sen- Sitiveness excessive, its interactions of energy rapid and incessant. . Its powers of change and of new formation of conditions are vast as compared with those of physical objects. And the molding of the mind of man by nature is but slightly due to its direct sensations from external objects. It is:very’ largely produced through the medium of other minds, since a leverage exists between mind and mind as between mind and Matter in producing conformity of conditions. In this indirect way a single mind may have been brought into conformity with ` outer nature through the intermediate influence of millions of other minds, exercised through the preservation of their ideas in books, or through their effects‘upon human society. ' We may close here with a brief consideration of the status of the human mind if its development could be continued to infinity. In such a case it would necessarily become an infinitely complete reproduction or representation of the universe, and infinitely sen- sitive and mobile to any modifications taking place in the vast domain of space. In the second place, it would be infinitely capable of producing within itself new combinations of energy.” It would thus be far more than an image of the universe, since to this it would add a second universe of self-formed ideas. In the third place, it would be infinitely capable of reproducing these ideas in outer nature, and thus bringing the universe into con- formity with itself. Man’s powers in this respect are limited, yet without changing place he has, by availing himself of the motor Principles and physical conditions of nature, a very extended Teach. As one example, by making the telegraph wire a virtual 1076 Lhe Relations of Mind and Matter. | November, extension of his body, he may exert a physical influence many thousand miles away. An infinite mind might possess infinite command of these conditions and principles, and produce effects reaching to the limits of the universe. Fourthly, consciousness would become extraordinarily developed in such a mind, and its whole vast range of memories be present at will. Prevision would have a like extraordinary development. In short, in such a mind all that we include in the name Deity would exist. It would not be the deity of pantheism, the soul of the world, any more than man’s mind is the soul of the machine he has devised, and whose motion he controls. The energies of nature would exist separately from those of the deific mind, but they would be ` mirrored in this mind, and would be infinitely and endlessly sub- ject to its control. That any developing mind could reach infinity of development is, of course, impossible. If such a being as the one here con- sidered exists, it must be as a co-eternal existence with the uni- verse, a primordial equivalent in conscious of the physical uni- verse in unconscious conditions. Yet consciousness and varying activity could not exist, even in such a deific mind, except through the impulse of energy received from without. Between sucha mind and the universe there must be an incessant interchange of energies, with consequent modifications in the condition of each. But the mobility of mental, as compared with the sluggishness of inorganic change, must necessarily make the former the ruling agent. Once in harmonious agreement with external conditions, it would subsequently, by its rapidity of ideal combination oF construction, impose constant new conditions upon external nature, and become the sole active moving force in evolution, thinking out the universe, as it were, and embodying all its thoughts in substance. This idea is offered as a curious specula- tion only, a corollary from the view of the mental constitution above taken, and as a hypothetical contribution to the somewhat extended list of theistical theories extant.

While regard for human life distinguishes the European branches of the Aryan race, it can learn a good deal from some of the other branches and races in the matter of similar humanity to the lower animals. The destruction of harmless reptiles, al- most universal among the less educated members of the white race, is not practiced by some of the others, notably by the Hin- doos, who might be readily excused for wholesale extermination, such is the number of venomous species in their country. The kindness of this and other races to the wild Mammalia is well known. In few countries would be practiced, except by boys and Savages, the wanton firing on bison from railroad trains, such as was common in this country while that fine animal was still abundant. Few civilized people would disgrace themselves as some of our English visitors formerly did by shooting scores of buffalo which would only walk away from them. It is still a favorite pastime for equally thoughtless “ sportsmen” to shoot from steamers in Southern waters that last representative of the great saurians, the alligator. The destruction of animal life for useful purposes is of course necessary, but here the greatest folly goes hand in hand with the greatest inhumanity. When it is a question of the natural pro- ducts of the earth, bison, alligators, and in fact almost all wild animals have important economic values, and the intelligent €conomist will preserve them on this account alone. But it is the Custom, in this country at least, to kill the goose that lays the golden egg, and to let the proprietor of sheol take the hindmost. Such is the destruction of fishes by dynamite cartridges, a prac- tice in which none but an idiot could indulge, and which is for- tunately punished by severe penalties. The latest case of wanton destruction is the sweeping of our Atlantic coast of surface fishes by the nets towed by the steamers of the U. S. Menhaden Oil and Guano Association. According to the statistics gathered by the investigating committee of the Senate of New Jersey, 450,- 000,000 of menhaden were captured during the year 1881, and 350,000,000 during 1882, and so on, and with them an enormous number of mackerel, blue-fish, weak-fish, etc. From one of the Steamers 70,000 lbs. of food fishes were purchased in thirty days. 1078 Editors’ Table. [ November, The testimony of all classes of fishermen shows that nearly all species of food fishes have been more than decimated by the operations of this company during a very few years. Here isa case where legislation is needed on behalf of the economic inter- ests of fish consumers, and it is to be hoped that Senator Sewell’s bill will receive due attention from Congress, and that the United States Fish Commission may become the executors of a strin- gent law. The destruction of menhaden alone should also be restricted, since that means the extinction of a large number of marine animals which live on them, mediately or immediately. There is a surprising shortsightedness in all these methods of destroying animal life which is not characteristic of the best representatives of our race. In general, animal products stored in the earth will be found to be more extensive and more inex- haustible sources of supply than the bodies of the existing ani- mals themselves. It would be better to let animals live and con- ee a 1885. ] Recent Literature, 1079 cestral form of historic man, whose skeleton has not yet been discovered, but who has made himself known to us in the clear- est manner by his works. A number of flints were exhibited from the strata in question which had been intentionally chipped and exposed to fire. It appears that M. Mortillet carried his audience along with him, for after a long discussion the almost unanimous opinion was expressed, “that after this meeting and discussion at Greno- ble, there can no longer be a doubt of the existence in the Ter- tiary period of an ancestral form of man!” It is to be doubted, however, whether the slight amount of evi- dence which jeaves no doubt in the minds of the French anthro- pologists will be altogether satisfactory to some of the doubting Thomases in this line of study. We shall want to examine the skull and bones, and other more conclusive evidences of human or semihuman art than those as yet discovered. Until then the truly cautious and scientific mind will hold itself in suspense. Sustaining its educational interests and progress. It is well- known that some branches of scientific research are too expen- Sive to be carried on by private individuals, excepting those of the greatest wealth, and that such persons are very rarely in- terested in science. Our neighbors of the Republic of Mexico are following in our own footsteps, in this respect, in the establishment of a Comision Cientifica. This body is composed of the most learned men selected from all parts of the country, and is under the presidency of Dr. Fernando Ferrari-Perez of Puebla. Its object is research in every department of human knowledge. It is making extensive collections of all the natural products of the country, and will be, as we anticipate, of great advantage to the best interests of Mexico. — o RECENT LITERATURE.

GENERAL.—The Royal Geographical Society have adopted in the spelling of geographical names a set of rules, the general use of which will do much to avoid the present confusion. Familiar names, such as Calcutta, Celebes, Mecca, etc., will be retained in their present form, but with these exceptions foreign names in countries which use Roman letters will be spelled as by the re- spective nations. The true sound of the word as locally pro- nounced will be taken as the basis of the spelling, but only an approximation will be aimed at, no attempt will be made to rep- resent the more delicate inflections of sound and accent. The vowels will be pronounced as in Italian, and the consonants as in English; every letter will be pronounced, and the only accent used will be the acute, placed upon the syllable on which stress | is laid. Indian names (East Indian) are accepted as spelled in | Hunter’s Gazetteer. Thus: Fiji and Zulu are accepted spellings, . not Feejee and Zooloo. All vowels are shortened in sound by | doubling the following consonant, and the doubling of a vowel | is only necessary when there is a distinct repetition of the single ; sound, as in Oosima. Au is to be pronounced ow as in how, not Corea; the oriental gutturals kh and gh will be used; kw will be used for qu (Kwangtung), and y is always a consonant, and should therefore never be used at the end of a word.

Three years afterwards this was revised by Capt. Baudouin, and the scale increased to I: 1,500,000.

From Cape Guir or Ghir to the Al- gerian frontier the length of the great Atlas range was known to be 435 miles, but only four points had been determined by pre- vious itineraries. . de Foucauld crossed the chain at several new points, of which he determined the altitude, besides journey- ing 185 miles along the base of the range, studying the orography of the country. The main range is flanked by parallel lines of elevation. There is in the north a chain of mountains 185 miles long, which bears the names of Djebel-Ait-Seri and Djebel-Beni- Uaghain, and in the south there is first of all the Little Atlas, and further south the strange outline of the Djebel-Bani range. In Dec., 1883, M. Foucauld touched the Wady Dhra’a to the south of Tattas. It was dry. Later on he ‘saw it further to the north-east, in the district of Mezquita, where it flows through plantations of date-palms. The part of this river indicated on Dr. Rohlfs’ maps is by M. de Foucauld placed one degree fur- ther west. M. H. Duveyrier, the writer of the report of M. Foucauld’s journey, is now traveling in Morocco. African News.—The Rev. G. Grenfell has contributed to the Royal Geographical Society a chart of the Mobangi, which proves to be a great navigable stream, flowing nearly from north to south across the blank on our present maps of Africa between the sources of the Benue and Shari to the Congo. Mr. Grenfell - ascended this river from its junction with the Congo, in a delta extending from 26 to 42 minutes south of the equator, to 4° 27 N. latitude. Throughout the whole district it is a magnificent stream, with a mean depth of twenty-five feet, and at the furthest point it was still an open water-way. The country around is richly wooded and seems fertile, and the banks are more densely popu- lated than those of the Congo. Itis full of islands. Professor Ratzel, in Petermann’s Mitteilungen for July, seeks to show how misleading it is to color a map of Africa with definite politi- boundaries. The state of culture in Africa is as varied as th ethnology, and these stages of culture are the prime element in the so-called political geography of Africa. Professor Ratzel divides Africa into twelve “State-forming” peoples, under the two great sections of North African and Soudan States, and different to that followed by Mr. Jos. Thomson, via Chagga and the Masai country, to the eastern shores of Victoria Nyanza.—— _ Some Swedish merchants have purchased a tract of land in the — Cam ns, and have established a considerable trade with the natives.

Nothing was heard of him in the Yoruba country, because he passed 200 miles to the east of it.

The Eyo is a mile in width at its mouth. Banks of rocks bar the entrance, but the left arm is navigable for vessels drawing two meters of water. The banks are marshy. M. Guiral ascended it about thirty kilometers, to Ini- ger, where there are falls. It has several tributaries, some of them navigable for canoes. The Dote is a river of little importance, with marshy banks, and is about a meter deep and forty meters wide along the lower part of its course. It can be ascended in a canoe for about twenty-one miles. The commerce of the district concentrates in the village on the right bank from which it takes its name. The natives are tall and are good canoe-men, but given to brandy.

America.—American News—In the August number of the Proceedings of the Royal Geographical Society, Mr. E. im Thurn gives a full account of the difficulties incurred in the journey to and ascent of Roraima, as well as of the botanical rewards ob- tained. The general aspect of all the plants on the summit 1$ dwarf, almost alpine, but many lovely flowering plants, including one closely resembling the crown imperial, and a luxuriant pitcher- plant (Heliamphora) occurred, with a few ferns and one shrub five or six feet high. The top of the mountain is not flat, but forms a shallow basin, the edge formed by the rugged edge of the cliff This basin is divided up into a vast number of smaller shallow basins, separated by curiously terraced ridges of rock, often of crescentic or even ring-like shape. These basins hold a quantity of water, and every shower of rain suffices to swell the water to such an extent that cascades fall over the cliff. Sir Robert Schomburgk states that the water seems to flow, not from the top of the cliff, but from points some distance below. his is readily explained, for it flows through deep and narrow sloping channels, often cut parallel with the face of the cliff and hidden by projecting promontories. The statement of previous travelers which Mr. Im Thurn found hardest to explain was that the top 15 covered with trees. This has been made with reference to the southern end, where there are certainly none, and our traveler believes that the rugged pinnacles and points of rock have been mistaken for trees. M. Chaffanjon, writing from Ciudad Bolivar, in May, states that with two Ariqua Indians he passed up the Caura river to its source, and obtained a mass of curious infor- mation respecting the manners and religious beliefs of the Arebatas, Penares and other tribes, He was also able to visit and study the Yaruras and Mapayes.

The journey demonstrates that a trade route is open in this direction in summer. Cols. Lockhart and Woodthorpe have been despatched with a party to Gilghit, and it is intended that full surveys of the region lying to the north-west of Kashmir shall be executed. Several passes of no great difficulty here lead towards the Russian possessions, which approach closely. Colonel Woodthorpe has just completed a journey through the Singpho country. He penetrated into the land of the Bor Khamptis on the northern Irawadi, where no traveler is believed to have been since Lieutenant Wilcox’s tour in 1828. Several mines lie north-east of Pedan, the capital, and are worked by an inferior and half-subject race called Khanungs. The Irawadi is unnavigable at Pedan. The journeys of Dr. Neis in Central aos (more than 3000 miles) have resulted in a vast amount of information regarding the commercial routes of the western basin of the Mekong, the anthropology and ethnology of the Laos and the Khas, and the social, commercial and political con- dition of the regions visited. Europe.—- European News.— Recent examination of bench marks made in 1851 along the Swedish coast of the Baltic show that the movement of elevation was continued in the north, and that of depression in the south of the Scandinavian peninsula. Compared with previous observations, the results prove that since 1750 the head of the Gulf of Bothnia has risen 2.10 meters. About Calmar and Carlscrona no change of level could be detect- ed, but the general result is an elevation of the Swedish coast at e mean rate of 1.60 meter per century. Four arctic expedi- tions are said to be projected for next year. Holland will send one, Denmark one and Portugal, newly awakened, it would appear, to the love of discovery, will send two. All propose to Visit the Russian islands of the glacial ocean, but the Danish expedition will specially explore the Kara sea, to define as far as possible the unknown region which is supposed to lie to the north-east of Novaya Zemlya.—The captains of several Norwe- gian steamers despatched to Greenland for seal-hunting, report that the east and south coasts are so obstructed by ice that no Seals have been killed. The population of Iceland in 1880 was 72,445, all of whom were Lutherans, except 3 Mormons, 1 Catho- lic, 1 Unitarian, 1 Methodist and 3 of no religion in particular. GEOLOGY AND PALAONTOLOGY. ON THE PRESENCE OF ZONES OF CERTAIN SILICATES ABOUT THE OLIVINE OCCURRING IN ANORTHOSITE ROCKS FROM THE River Sacuenay.—While engaged during the summer of 1884 i 1088 General Notes. [ November, in making a geological examination of a portion of what has proved to be a very extensive area of anorthosite rocks, which belong to what has been called the Norian or Labrador series, occurring about Lake St. John and the Upper Saguenay, and which from thence strikes far away to the north, I noticed in many of these rocks a mineral which weathered to an orange color and which, when the weathered surface of a specimen containing it was care- fully examined, was invariably seen to be surrounded by a nar- row light green border. On my return to Ottawa in the fall a large number of thin sections of these rocks were prepared and were found on examination to exhibit a most interesting phenom- enon, which I propose here to describe briefly. The mineral olivine has never heretofore been mentioned as occurring in the Norian series in Canada, although Dr. Hunt, I believe, has mentioned it as a constituent of certain boulders of anorthosite rock, referable to this series, which were found in New Hampshire, but which were probably carried thither from Canada during the glacial age. The mineral, however, occurs abundantly in the anorthosite of many parts of the Saguenay area, and I have also found it in a specimen from a little area of rocks which has been referred to this series, and which occurs near Dolin’s lake, in New Brunswick. en thin sections of the massive or nearly massive dark violet anorthosite from the shore of Lake St. John, near the Little Discharge of the Saguenay, is examined with the microscope, the rock is found to be composed of plagioclase, olivine and iron ore. The plagioclase occurs in large well twinned individuals, which are seldom broken or twisted, and which between crossed trichols show nothing of the peculiar, wavy appearance so often seen in the feldspar of the Laurentian gneiss. The iron ore which is pres- ent only in small amount is probably titaniferous, as in one slide a grain of it is seen partially altered to leucoxene. The olivine, of which the rock usually contains a large quantity, occurs either 1n single individuals, or especially in the larger grains, as several in- dividuals united to form one grain. They seldom have any re- semblance to proper crystalline forms, but one usually irregular in shape, a single individual sometimes forming a very irregular elongated string. It is recognized by its bianial character, high index of refraction and imperfect cleavage, and although like the plagioclase very fresh, by the presence of a little serpentine which here and there may be detected along the cracks which traverse it. The olivine, as is usually the case in eruptive rocks, crystal- lized before the plagioclase and therefore lies imbedded in it; but _ although I have examined a very large number of thin sections of this rock, I have never been able to find these two minerals in contact, there being invariably two zones of certain other silicates urrounding - olivine and intervening between it and the €, so that since the rock consists almost entirely of these r 1885. ] Geology and Paleontology. 1089 two minerals, every grain of olivine is seen to be completely sur- rounded by this double zone. The zone, next to the olivine, is colorless, or nearly so, but often shows a slight pleochroism with reddish andegreenish tints. It is formed of small individuals, grown compactly together and considerably elongated in a direction at right angles to the sur- face of the olivine. When examined with a high power the min- eral is seen to possess two sets of imperfect cleavages, and when these cross one another at right angles, the direction of extinction bisects the right angle. When cut perpendicular to an optic axis, it shows the revolving bar of a biaxial crystal. The second zone, or that next to the plagioclase, forms a fringe about the zone just described and consists of minute needles of a light green fibrous mineral arranged at right angles to the sur- face of the inner zone and penetrating into the plagioclase, so that their examination is attended with considerable difficulty. They are, however, seen to be slightly pleochroic with different Shades of green and to have an extinction which makes a small angle with the length of the fibers. It has exactly the appear- ance of actinolite, as that mineral is generally seen in thin sec- tions, and that it is really a variety of hornblende is proved by the fact that in another specimen of the same rock collected a few miles away, in which the zones are still seen in all their per- fection, the outer one is no longer fibrous, but shows the cleavage and absorption characteristic of hornblende. The olivine and the minerals composing the two zones are en- tirely differently orientated, and the breadth of the zones does not bear any absolutely constant relation to the size of the olivine grain as seen inthe slide, since this latter would vary greatly, accord- ing to the direction in which the section passed through it. Th inner zone, however, is always smaller than the outer one. Although the mineral forming the inner zone has the char- acters of a pyroxene, no conclusive evidence as to its nature could be obtained from the sections of this rock. Similar double zones are, however, found about the olivine in rocks from other Parts of the area having the individuals of the inner zone better developed. In these the pleochroism and rude cleavage are very distinct. Ina section of one of these rocks a grain of pyroxene exactly resembling the mineral of the inner zone, but not asso- Ciated with the olivine, was so cut that it could be proved to be a rhombic pyroxene, in that on a basal section known by the cleav- ages being at right angles a bisectrix could be seen. It may there- fore be said that the inner zone is probably composed ofa rhombic obtained. This I propose to attempt, and will make known the » 1090 General Notes. [ November, result in a paper on these rocks which is now in course of prepa- ration. Although these zones have been mentioned by three or four writers, Dr. Tornebohm, who first observed them in certain gabbros from Sweden (Neues Jahrbuch fiir Mineralogie, &c., 1877, p. 383), is, so far as I am aware, the only one who has described them. Owing to the kindness of that gentleman I have had an opportunity of examining thin sections of a number of these wedish rocks. The double zone is well seen in them, but is much smaller than in the Canadian rocks, and the minerals com- posing it accordingly more difficult to determine. Dr. Tornebohm, although unable from kis sections to determine the nature of the inner zone, rightly regarded the outer one as hornblende. The chief interest attached to these zones arises from the fact that, as Tornebohm remarks, they appear to have originated from a mutual reaction between the olivine and the plagioclase. An examination of the thin sections of the Saguenay rock impresses one strongly with the conviction that they have resulted from the action of the molten plagioclase magma on the olivine grains, which in eruptive rocks always separate out before the plagioclase, thus having an origin similar to the kelyphite zones about pyrope described by Schrauf, and somewhat analagous to the zones about olivine and hornblende in volcanic rocks, which have recently attracted so much attention. The subject is one of importance as indicative of the processes at work in the genesis of rocks, and also as throwing some light on the much discussed question of — the origin of these anorthosite rocks.—Frank D. Adams, Geological Survey of Canada. EocENE PADDLE-FISH AND GONORHYNCHID#.—The Polyodon- tide or paddle-fish are only known from the American and Chi- nese rivers, and no trace of them has been found hitherto in the records of earlier periods of time. It is therefore of much interest to zodlogy that I am able to announce the existence of remains of a species of this family in the Eocene Green River shales of Wyo- ming Territory. This determination is based on a skull, of which one side is fairly well preserved, of an individual of the size of a middle-aged specimen of the common paddle-fish (Polyodon folium). The long snout is somewhat damaged, but was less dilated than in that species, being intermediate in character between the snouts of the American and Chinese forms (Psephurus gladius). The stellate bones are smaller and more attenuated than in the F- _ folium, and the gape of the mouth is not quite so wide. , The symphyseal bone, enclosing Meckel’s cartilage behind, is much smaller. There isa bone in contact with the front of the oper- culum below, which may be one of two or three elements, which pparently not present in Polyodon, at least not in that posi- reason I propose to distinguish th ic fish cenerically 1885.] Geology and Fateontology. ” TOQI from Polyodon.

The species, which is repre- sented in my collection by two fine specimens, is about as large as a fully grown pickerel, but of more slender proportions. The head is short and the mouth small and edentulous. In its gene- ric characters it agrees generally with Gonorhynchus, but differs in the absence of prominent hyoid and pterygoid teeth. The scales are broadly fringed at the margin, like those of the cotem- porary genus of Aphredodiridæ, Amphiplaga, and the Tricho- phanes of the Amyzon beds.

Stan- ley, F.G.S., had the following points: The theory of Dr. Croll, accepted by many geologists, is that former glacial periods in the ` Northern hemisphere were due to greater eccentricity of the earth’s orbit and to this hemisphere being at the time of glacia- tion in winter perihelion. This theory is supported upon condi- tions that are stated to rule approximately at the present time in the Southern hemisphere, which is assumed to be the colder. Recent researches by Ferrel and Dr. Hann, with the aid of temperature observations taken by the recent transit of Venus expeditions, have shown that the mean temperature of the southern hemi- sphere is equal to, if not higher, than the northern, the propor- i The conditions that tude, whereas in the north frozen ground in certain districts, as in Siberia and Northwestern Canada, extends beyond the fiftieth parallel; therefore, by comparison, the north, as regards the lati- tude in which Great Britain is situated, is at present the most 1092 - General Notes. [ November, glaciated hemisphere. As it is very difficult to conceive that the earth had at any former period a lower initial temperature, or that the sun possessed less heating power, glaciation in the north could never have depended upon the conditions argued in Dr. Croll’s theory. The author suggested that glaciation within lati- tudes between 40° and 60° was probably at all periods a local phenomenon depending upon the direction taken by aérial and oceanic currents, as, for instance, Greenland is at present glaciated. Norway has a mild climate in the same latitude, the one being situated in the predominating northern Atlantic currents, the other in the southern. Certain physical changes suggested in the distribution of land would reverse these conditions and ren- der Greenland the warmer climate, Norway the colder. OCCURRENCE OF A DEEP-SEA FoRAMINIFER IN AUSTRALIAN M10: CENE Rocks.—At the meeting of the Royal Society of South Australia, on June 2, Mr. W. Howchin, F.G.S., exhibited a speci- men of Astrorhiza angulosa as a fossil found in the Miocene strata of Victoria. The specimen was stated to be of more than ordinary interest, inasmuch as it was the first instance in which the genus had been found in the fossil condition in the recent slate. The species submitted was very rare, having been hitherto known to occur only at two localities, one of these being at a Challenger station to the east of the Azores, at a depth of 1000 fathoms, and the other at a point in the North Atlantic, dredged by the Porcupine, at 630 fathoms, where only a single specimen was taken. There are five species in the genus, but with the ex- ception of a single specimen of an allied species taken by the Challenger off the Cape of Good Hope, the genus is only known as a North Atlantic type. The species discovered in the’ Victorian rocks is one of the rarest ; its occurrence, therefore in the fossil condition in the Australian Tertiaries is a matter of some inter- est. The speaker stated that his researches with regard to the microzoa of the Australian formation led him to believe that -many of the rarer arenaceous forms of foraminifera recently dis- covered in the deep seas, and which have been so beautifully illustrated by Mr. H. B. Brady in the Scientific Results of the Challenger Expedition, occurred as fossils in Australian geology from the Cretaceous formation downwards.—English Mechanic. GEOLOGICAL News.—General—Prof. P. M. Duncan has con- 1885.] Geology and Palæontology, 1003 more than the opercula of Goniatites. Both agree, however, that for other forms this explanation is, according to our present knowledge, inadmissible. W. Dames, however, asserts that none are phyllopodous in their nature, a dogmatic opinion for which he is taken to task by the English palæontologist. They are, in fact, species of Phyllocarida, and not phyllopods. Carboniferous—Since 1878 no less than 1300 specimens of fossil insects have been obtained at Commentry, while all other localities have only furnished about 120 examples. These Com- mentry insects are remarkably well preserved, many of them being complete, instead of consisting of the wings only, as is often the case with insect remains. M. Ch. Brongniart (Revue Scientifique, 29 Aout, 1885) classifies these carboniferous insects as Orthoptera, Neurorthoptera, Pseudo-neuroptera, and Hemip- tera. Among the Orthoptera are fifty specimens of Dasyleptus lucasi, an ancestral Thysanouran, and numerous Palæoblattariæ and Palzderidiodea. The Neurorthoptera comprise the order of that name and the Palezodictyoptera; the first with the families Protophasmida and Sthenaropterida, and the second with the families Stenodictyopterida, Hadrobrachypoda, and Platypterida. The wings of Archeoptilus lucasi are twenty- five to thirty centimeters long, and those of Eugereon and other Stenodictyopterida are finely netted like those of dragonflies. The Hadrobrachypoda are regarded as ancestral Their wings are broad, generally rounded at the end, and though morphologically like those of the Protophasmida, differ greatly in the nervation. The nerves are well sepa- Tated, and the wings colored. Six familes of Pseudo-neurop- tera can be distinguished, the Megascopterida, Protodonata, Homothetida, and three others containing the ancestral types of the Ephemeridz, Perlide, and Ascalaphus. The Hemiptera are represented by types of the Fulgoride and Cicadide. Cretaceous —Mr. J. S. Gardner denies the synchronism of a large part of the American Cretaceous with that of England. Whether the former are Cretaceous at all is debatable. The question whether a Cretaceous fauna extended into the Eocene, Or an Eocene flora extended back to the Cretaceous is answered by Mr. Gardner in these words: “ In support of the first propo- sition we have the innumerable survivals of old. types at the ence of any distinctly Cretaceous plants. I think all the evi- dence I have been able to bring forward is in favor of a newer rather than an older date, and this is decidedly more in harmony . with the march of evolution.” Mr. J. S. Gardner (Quart. Jour. 1094 General Notes. [ November, Geol. Soc., Feb., 1884) describes the British Cretaceous Nuculide. Paleontology bears out the separation of the Nuculæ and Lede from the Arcide. He recognizes fifteen species of Nucula in the limits treated, ten of the group of Ovatæ, the remainder of the group Angulate. The Lede are ten in number. Nucula meyeri, Nucula gaultina and Leda seeleyi are new species. as “Pretertiary continental formations”: Vegetable soil (loam with lignite in its upper bed), flint conglomerate (sand with be- neath it clay with flints), Pretertiary loam (loam, plastic clay and sand) and transported Pretertiary deposits. The Eocene is divided into Montian, Landenian, Ypresian and Parisian, the last characterized by Rostellaria ampla, Nummulites levigata and variolaria, Ditrupa strangulata, and its glauconitic zone by Pecten corneus. In the Eocene of Northern France the only vertebrates known are Arctocyon primevus and Pachynolophus maldani, but the Oligocene has yielded Anthracotherium and many birds, also Crassitherium robustum, allied to Rhytina. M. Gosselet divides the Oligocene into Tongrian (principally marls and sands) and Rupelian (Beauce limestone). The Neogene is represented in Northern France and Belgium only by its upper or Pliocene beds. The description of chilostomatous Bryozoa from Al- dinga and the Murray Cliffs, S. Australia, by A. W. Waters, 1S still continued in the quarterly journal of the Geological Society. The number of fossil species now known is 220, just about hal of which have been found living. They are principally from the Tertiary, but a few are Cretaceous. È. T. Newton (Geo. Mag., Aug., 1885,) describes some bones of a gigantic bird obtained from the Lower Eocene at Croydon, Eng. The most interesting portions are two large tibiæ-tarsi and parts of a femur. ese bones very closely resemble the corresponding parts of Gastorms arisiensis, but present specific differences. The bird, which must have been as large and heavy in build as the Dinornis crassus of New Zealand, has been named G. -Al/aasenii in honor : of its discoverer, Mr. H. M. Klaasen. Recent.—The two articles of Prof. J, D. Dana (Amer. Journ. of Science, Aug., Sept., 1885), are an able defence of the until p cently almost universally accepted theory of the origin of pe reefs and islands by subsidence. The great number of atolls an barriers in all stages to be found in the deep belt of the Pacific, _ are shown to be inexplainable upon any other theory, while islands like the Marquesas, though without reefs, yield a able evidence of the wide spread subsidence. The views, P and Dana are shown to be those of men who had a wi a ee ee 1885. ] Mineralogy and Petrography. _ 1095 acquaintance with the general phenomena; it is admitted that local elevations occurred, and some of the widely isolated points thus elevated are enumerated, and other explanations of the phenomena are passed under review, but dismissed as either in- sufficient or actually confirmatory of Darwin’s theory. The soundings of Mr. Murray off northern Tahita, showing the rapid increase of depth beyond the forty fathom line until, at a mile from the shore, the slope of the ocean bottom was nearly that of the land, are shown to be exactly in accordance with the subsi- dence theory. The strongest evidence, derived from the writings of A. Agassiz and the soundings of the Blake, points to a great subsidence in the Florida region during the coral reef era, and the elongation of the coral reefs and formation of inner channels now going on by drifting coral sands is shown to be but a part of the sand-beach forming process which is in operation along the entire Atlantic coast of North America, from Long Island southward, and to in no way vitiate the evidence in favor of pre- vious subsidence. The abrasion-solution theory of Semper seems to be negatived by the absence of open channels in the lagoons of the smaller atolls, moreover, instead of small lagoons having the purest waters, it is they which are most choked by coral sands. Almost perfect skeletons of Rhyttna gigas have been recently mounted in the National Museum, Washington, and in the British Museum. MINERALOGY AND PETROGRAPHY.' New Minerats.—Gerhardite— Messrs. Wells and Penfield? have described natural crystals of a basic copper nitrate which ‘was first identified by Professor Brush, of New Haven, on speci- mens of copper ore from the United Verde mines, Jerome, Ari- zona.

Phenacite, zircon, topaz, cassiterite, uorite and several other species also occur in the granite of Pike's Peak, in addition to the common microcline and smoky quartz. Minor investigations on the luster of sanidine in certain rhyolites ; on the occurrence of topaz in nevadite; short notes on many ob- served minerals, including the two new species zunyite and guiter- manite, already mentioned in the Naturatist’s notes, make up the other chapters. Bulletin No. 12 of the U. S. Geological Survey contains a ve interesting study, by Professor E. S. Dana, of “thinolite,” a name applied by Mr. Clarence King to an enigmatical calcite pseudomorph which occurs abundantly in the old lake basins of the far West. This mineral was at first considered a pseudomorph after gaylussite ; Professor Dana, however, shows that this cannot be the case as the original form was clearly tetragonal. What the ‘chemical composition of the original mineral was, it is impossible to state with certainty, but judging from the analogy of well-know n lead-carbonate pseudomorphs after phosgenite (PbCO; + PbCl,), the author thinks it quite probable that the original form may lave been a similar double salt with the composition CaCO; + NaC? or CaCO, 4 2NaCl. _ M.S.

A microscopic exam- ination of thin sections of these crystals shows that they are divided into four secants with a faint irregular action on polarized light. Very many crystals show a perfect but small trisocta- hedron in their center, around which the exterior portion appears to be a secondary growth. Mr. J. P. Iddings! of the U. S. Geological Survey communi- cates a very interesting account of minute fayalite crystals which occur in the lithophyses of the obsidian and rhyolite in the Yel- lowstone Park.

THE GROWTH OF PLANTS WATERED WITH Acip Soxutions.—In the September and October numbers of the AMERICAN NATURAL- Ist for 1883, the writer published the results of an examination of the effects of watering, with acid solutions, growing plants of the silver-leaf geranium, and he there stated his intention of con- tinuing his experiments in this direction by growing the same plant under similar or identical conditions upon siliceous, feld- spathic and calcareous soils. ese experiments were made in the summer of 1884, and the results obtained form the substance of this paper. The conclusion seemed warranted by my previous experiments that the acids had a tendency to increase the ash or mineral in- gredients of the plant, and this inference led me to suppose that if the soils used were highly mineralized the deleterious action of the acids upon the plant tissue would be diminished and at the same time the introduction into the plant of mineral substances increased. The soils were prepared and the plants potted about July īst, the proportion of pulverized mineral in all cases being from twenty-five to thirty per cent of the whole, for the silica common cement sand was used, and the earth was taken from garden mold. The strengths of the acid solutions used were as follows : Of hydrochloric, nitric, sulphuric and carbolic 10° of the concentrated acid to one liter of water; of oxalic, tartaric, tannic, citric and formic 20% of the saturated solutions to one liter of water. Ordinary flesh-colored feldspar from granite veins in the gneiss rock of Manhattan island was powdered and used for the feldspathic tests, and dolomitic marble from Westchester county similarly treated and mixed in thoroughly with the mol to make a calcareous soil. _ The tables following show the results obtained in all my exper- iments, including those of 1882. The first set of tables shows the state of leafiness of the plants at different times, and the sec- ond the percentage of ash with the weight of the dried plant at the end of the experiment.

The flat surface is usually more highly polished than the other. In Fig. 2 we have a very unique example of the linear celt, both ends being sharpened and one transversely to the,other. It is not common to find each end ground to an edge, but I have seen only this specimen in which the line of one edge crossed that of the other. It is a very finely made implement of com- pact basalt. It was found several feet below the surface in the ubsoil, in Weybridge, by Mr. A. J. Stowe. It is nearly six ong and about one inch in greatest width. 1885. ] The Stone Ax in Vermont, 1147 Still another type of celt is shown in Fig. 3, which was found in the same locality. The usually flat surfaces are beveled from a median ridge, as shown in the figure, to the sides. The mate- rial is a greenish quartzite and the specimen is very well finished, though not as well as many. It is six anda half inches long, two and a half wide and rather more than one inch in thickness, The second class of celts are quadrangular in outline. Some of these are large and rude, others small and well made, but as a class they are rude and apparently made for rough work. In some cases, however, they are not strong, but, as in case of the speci- men shown in Fig. 4, the material is some sort of slate, and too brittle for other than light work. Much larger specimens of this sort than that shown in Fig. 4, which is only four inches long, occur. One of these is of blu- ish serpentine, and was polished over the entire surface, although it was not worked smooth, and hence retains the irregularities made by the cleavage, It is nine inches long and more than four wide, On page 433 of Volume xv of this Fig. 4. X % journal, figure 6, is shown a specimen which illustrates the gen- eral form of the typical celt of this class, only substituting for the concave end an edge like the upper one in the figure. Very many are ground to an edge at each end, and these are much more _ carefully made than others which have but one edge. Fig. 5 shows a type of our third class of celts, those which are quadrangular in outline but narrower at one end than the other, and the narrow end, if there is but one edge, is always that which is blunt. Often in celts of this form each end is brought to an edge, as in the case of Fig. 5, though this is less common than in celts of the second class. These celts are mostly very nicely made and of handsome mate- rial, and often beautifully polished. Some of them resemble closely the small celts found in the Swiss lakes, For the most part they are not of large size, averaging, perhaps, three or four inches in length. In none of our stone implements do we find 1148 The Stone Ax in Vermont, [ December, more beautiful specimens of ancient workmanship than in these celts, some of which, made from a compact, fine-grained serpen- tine of richly shaded green, are most elegant objects. There are beds of this handsome material in several localities in the State, and it is remarkable that no objects made from it have been found except some of the celts. Most of the celts ot the second and third groups are much wider than thick, but a few are either cylindrical or quadrangular in cross- -section, The globular form seen in celts from other localities never appears in Vermont. Our celts appear to have been mainly worked from pieces split from larger masses rather than as in some places from pebbles. A form of celt which may be regarded as a modifica- Fic.5. X % Fic. 6.

Possibly this is one of those specimens of which Lafiteau speaks when he says that they were not finished during a single lifetime, but were handed down as heirlooms to be highly valued. Certainly no short time would be sufficient for the manufacture of so perfect an implement from so hard a stone.

It is very smooth, and the edge is unusually sharp. Both surfaces are quite flat. It is nearly five inches long and three across the edge. Celts of this form are less common than those of the other classes, and are usually of me- dium size and of hard, compact mate- rial, such as quartz, of which several are made, or porphyry. They are almost always made with great care, and even those of granular quartz are polished about the edge and some- times over the entire surface. As any collector of stone implements will readily believe, there are many celts in our Vermont collections which do not clearly come within any one of the above groups, but are interme- diate in their character. Nevertheless Fic. 7. X % there are very few which cannot be placed in one or another of the four classes with sufficient accu- racy for a general description. It is rather remarkable that so few of our celts show broken or worn edges. Some of them do indeed bear abundant evidence of severe service, but most have sharp even edges as if only just from the maker’s hand. Either the larger part of these implements were skin-dressers, fleshers and the like, as doubtless some of them were, or if used for any work that broke or defaced the edge, they were very promptly repaired, and that this was sometimes done is familiar to every col- lector. The shape or bevel of the edge is by no means uniform. In some of our specimens the angle inclosing the edge iis very large, and the bevel abrupt and short, as in many of our modern tools used by iron workers, while in others it is less abrupt, and in most quite like the edge of our modern ax, for which at best the celt could have been only a very indifferent substitute, although as a flesher or skinning knife or scraper some of the forms may very well have served most excellently. 1150 The Relations of Mind and Matter. {[December, THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. (Continued from p. 1076, November number.) VII. Tue Puysicar Basis or MIND. HAT the mind has a substantial basis does not need an attempt at argument before a scientific audience. The neces- sity of this is already fully admitted. For those who are not scientists the arguments we have already given must suffice. The claim that the brain is the organ of mind is based almost solely on this necessity. No other substance is perceptible at the appa- rent seat of thought, and the cerebrum is claimed as this seat in spite of the insuperable difficulties in the way of such a theory. Yet there is much substance and much in substance which we cannot hope to éver perceive. Our senses are very imperfect in- struments, and make us aware of but a minor portion of what exists. Our most important sense, that of sight, is blind to the great realm of gaseous matter. The microscope reveals to us worlds of existence which the unassisted senses could never have discovered. By the aid of delicate tests and instruments many of the less gross and active conditions of matter have been made apparent. In this way the range of our sensibility has been very greatly increased. And yet we are but on the threshold of the universe, Important conditions exist to which the senses of man have never responded. Important conditions exist to which our physical senses can never respond. We have the strongest reason to believe in the existence of substance all around us of which we can never become sensible. Some review of the conditions under which substance appears to exist becomes here requisite. In the science of a century past matter was but one of several distinct forms of substance. It was accompanied by a number of ethers, or imponderable es- sences, one each for heat, electricity, magnetism, &c. Indeed, the facility with which a new ether could be constructed to meet _ every new phenomenon of energy threatened in time to produce _ a condition as cumbrous as the old epicycle theory of astronomy. _ That was set aside by the discovery that the earth was a moving instead of a resting body, and the ethers similarly vanished when was discovered that motion was the distinguishing feature in em al From this tradiness to manufacture ethers the pendu- 1885.] The Relations of Mind and Matter. TISI lum of belief swung to its opposite side, and a general incredulity on the whole subject of ethers succeeded. In more recent times this incredulity is giving way, and our most skillful physicists are fully persuaded of the existence of one ether, the medium of light radiations. To those scientists the universe contains twò distinct substances, matter and ether, which differ radically in their con- ditions of existence. Students of the phenomena of light declare that there is no possible escape from this conclusion. Interstellar space is prob- ably occupied by ordinary matter in a state of extreme diffusion, and it might be conjectured that the rays of light could make their way through this substance from star to star. Science de- clares that this is impossible. Matter, under such circumstances, must be a very rare gas, and no gas can transmit transverse vibrations like those of light. Its degree of diffusion also would be far too great and too irregular. To transmit the rays of light some substance is needed that is very elastic; that, while exceed- ingly rare, is far more dense than diffused matter would be in interstellar space ; and that is in the condition of a rigid solid instead of a free gas. Yet it must be a solid so readily permeable as to present no resistance whatever to the movement of the spheres. As a ball will sink with little resistance through a thin jelly, without leaving a mark of its passage, so must a globe be able to plunge unopposed through the almost infinitely thin jelly of the ether. , : Ether has never been seen, felt, weighed. or measured. It is absolutely invisible and intangible. No vessel has pores so minute as to confine it. It has properties seemingly contradic- tory ; it must be excessively rare yet perfectly elastic ; its physi- cal state must resemble that of the. solid while its density is im- mensely less. We have no proof of its existence resembling our proofs of the existence of matter, yet we are forced to believe in it because physical science cannot possibly do without it. There are hundreds of phenomena which cannot be explained without it, but can readily be explained with it. Sir William Thomson, in his lecture before the Franklin Insti- tute during the 1884 meeting of the American Association for the Advancement of Science, said of this intangible necessity : “You may regard the existence of a luminiferous ether as a reality of science.” “One thing we are sure of, and that is the 1152 The Relations of Mind and Matter. [ December, reality and substantiality of the luminiferous ether.” And he proceeds to say that it is the only thing we are confident of in dynamics. This ether he describes as an elastic solid, its rigidity enormous in proportion to its density. As to whether it pos- sesses weight or not he declares that there is no evidence for or against. J. Clerk Maxwell speaks as strongly on the subject, and finds a new use for the ether, as the medium of electric and magnetic energy. He advances a theory, which has met with much favor, that “light is an electro-magnetic phenomenon.” In other words, both these modes of traveling energy employ the same medium and are carried by it with a rapidity extraordinarily greater than any known movements of vibrations in matter, such as the waves of sound. Ether; therefore, is supposed to permeate all substances, however dense. It conveys electricity through the densest solids, and light through the densest transparents. -We can reduce air, by the air pump, to one hundred thousandth of its volume, and yet it is firmly held in a glass vessel. But light passes through the vessel, and through its partial vacuum, without a check, The substance which carries it moves as freely as if no other substance was present. There is, however, a seeming relation between matter and ether, if we accept the latest atomic theory, that of vortex mo- tion, propounded by Sir William Thomson. It is not necessary here to explain this theory ; it will suffice to say that it holds that fragments of the ether possess a vortical motion by which they become separate and indestructible integers. Each such vortex atom must have always existed and must always exist. They are indestructible and unchangeable. No new ones can arise, and no old ones can vanish. They must be coéternal with ether. Their substance is the same as the ether itself. They are simply portions of ether affected with a certain mode of motion. _ But as thus constituted they are essentialty distinct from ether, = and the two constitute two unlike conditions of substance. This conclusion i is probably true whatever the character of atoms, and ' r the vortex atom theory be correct or not. Teer Oliver Lodge gives the following particulars con- th this substance The density of ether, though small, is i aii l its Functions, ae Jan. 25, 1883. 1885.] The Relations of Mind and Matter. 1153 enormously greater than that of the earth’s atmosphere can be if the atmosphere extends indefinitely into space, as is highly prob- able. The rigidity of ether is insignificant as compared with ordinary solids, yet its transmitting power is enormously greater than that of steel or glass, on account of its very slight density. The ether within glass transmits vibrations 40,000 times as rapidly as the particles of glass itself could do. But the atmospheric ether carries these vibrations at a speed one-half greater. The speed, therefore, is checked within glass to two-thirds its normal amount. Why isthis? Is ether affected by gross matter, and concentrated by attraction so as to increase its density? Fres- nel’s hypothesis is, that the ether is really denser inside gross matter. He thinks that_an attraction exists between ether and the molecules of matter which results in an agglomeration or — binding of some ether round each atom, and that this bound ether belongs to the matter and travels with it. The free ether may flow without check through the pores of matter, and even through those of the earth as it dashes onward through space, Refraction of light from sucha cause is attributed to bound ether, which seems to act differently on the different colors. Certain experiments have been tried to prove whether any of the ether can be bound. If ether is carried along with a moving stream, as of water, it should hasten the speed of light passing through that stream, If not carried by the stream there could be no effect on the speed of light. The results of these experi- ments have been favorable to the hypothesis. Yet the variation in the speed of light from such a cause is so slight that it is difficult to reach any very positive conclusions on this subject. That ether possesses energy is unquestionable. It moves with such extreme readiness that it cannot fail to possess a large sum of normal motions. Its physical condition also is indicative of conditions of energy. Elasticity, rigidity, solidity are due in matter to the interactions of attraction and motion, and we have no warrant to ascribe them to any other cause in ether. But the motions normal to ether are certainly very different from those normal to matter, since ether refuses to accept the motions com- municated to it by matter. This is what we must understand from radiant light and heat. Matter forces its motions upon ether, but the latter substance refuses to absorb them, and merely transfers them, with the utmost rapidity, to some distant mass of r 1154 The Relations of Mind and Matter. [ December, matter. We know that the sun exists because its energy is trans- mitted to the earth by the ether, and acts upon the matter of the earth, Were not the ether a perfect transparent to this material energy we could never become aware of the existence of sun and stars, since their light and heat-rays would be swallowed up long before they could reach us. Ether is, in fact, the most homogeneous body in the universe. It is in a state of motor equilibrium, its motions probably being exceedingly more rapid than those of ordinary matter. It has no direct motor relations with matter, but transmits to distant matter all motion forced upon it, by aid of the vibrations of its par- ticles or separate portions, which are localized in position, like those of the solid. J. Clerk Maxwell speaks of it as follows: _ “ Whether this vast homogeneous mass of isotropic matter is fitted not only to be a medium of physical interaction between distant _ bodies, and to fulfill other physical functions of which, perhaps, we have as yet no conception, but also, as the authors of the Unseen Universe seem to suggest, to constitute the material organ- ism of beings exercising functions of life and mind as high as or higher than ours at present, is a question far transcending the limits of physical speculation.”! Not having read the Unseen Universe, I am unaware of the : precise character of its speculations, yet I cannot imagine the luminiferous ether as possessed of such powers. For life and mind organization seems necessary, and organized ether is dis- tinct from free ether, and must be some condition analogous to matter, which is probably one form of organized ether. Bound ether, or atom atmosphere, may represent such a second state of organized ether. For all we know to the contrary a second series of atoms may be formed by this condensing action of matter on ether, atoms intimately connected with matter and assimilated with it in motion, yet differing in density of substance and motor rapidity. It may be possible that several series of such atoms exist between matter and ether, each sapable, of forming a basis of life and mind. Whether orig y, or each rarer series formed by the condensing Aon a denser series, the 1885.] The Relations of Mind and Matter. IESS and only be absorbed by substance of the same series. The range of material vibrations seems to be from about a hundred million million, or perhaps lower, to sixteen hundred million mil- lion pulsations per second. The slowest vibration emitted by an atom of rarer constitution might lie above this speed, and range upward from this point of rapidity? It is with the bound ether that we are here concerned, that which, in the opinion of many able scientists, surrounds material atoms and molecules like an atmosphere. The existence of such an ethereal atmosphere carries with it the implication of some conformity in motion between the atom and its atmosphere on the same general principle that operates in the case of the earth’s atmosphere. And the condensing relation between the atom and its atmosphere can hardly be any other than that of attraction. Yet it does not necessarily follow that the motions of the bound ether must be in every respect identical with those of the atom it surrounds. A motor leverage doubtless exists between them, but leverage of a different character may act on this bound ether from without. It may possess special motor conditions of its. own, as the terrestrial atmosphere while possessing the general motions of the earth has special motions which are not shared by the solid matter of the earth’s mass. These conclusions seem almost necessary deductions from the widely accepted view, above given, of the relations of matter and ether. There is another conclusion, at which we have already hinted, not a necessary yet a conceivable consequence, This is, that bound ether may, under certain favoring conditions, attain an organized state not dependent upon that of matter, and be capa- ble of permanently retaining this condition, If, as is probable, molecules composed of many atoms possess an ethereal atmos- phere, then the disruption of the molecule need not necessarily disrupt its associated ether. Though ether is organizable under the influence of matter, vet the forces which disrupt gross matter might, in certain cases, become powerless upon ether. If so,a mass of ether which had been organized by the influence of a mass of matter might retain that organization unimpaired after 1 For an able and elaborate treatment of this subject see Professor A. S. Herschel’s letters in Wature, Vol. 27, pp- 458, 504, and Vol. 28, p. 294.. These were written in answers to articles by the writer on “ The Matter of Space,” and constitute an important treatise on the constitution of the ether, its relations to matter, and its possible atomic variations. 1156 The Relations of Mind and Matter. [December, the material mass had become disintegrated, and might continue to exist as a molecule or mass of a constitution much more rare than that of matter. Possibly this power of becoming independent does not exist in the case of atomic or molecular atmospheres of bound ether. But it may do so in the case of the bound ether of more devel- oped compounds. We may look upon the crystal, the plant, the animal, even on the body of man as possessing, in addition to the free ether that readily permeates them, a mass of condensed or bound ether which reproduces every detail of their organization and every specialty of their motion, from that of each atom to that of the organism asa whole. In sucha case the cerebrum might possess such an ethereal atmosphere, not only reproducing it in organization, but affected in its motor relations by every im- pulse received from without which is not consumed as muscular motion. There are certain good reasons for believing that such a psychic substance exists, intermediate in condition between matter and ether, and sending out vibratory energy like that of matter. This psychic substance yields no energies which can affect matter at a distance, and it is not affected by the emitted energies of distant matter. It can affect matter and be affected by it only while an intimate connection exists, like that between the cerebrum and its psychic atmosphere, and only through the agency of this connection. In this relation the psychic substance assumes the general motor conditions of the cerebrum, with which it is so intimately associated, and is also sensitive to special motor conditions coming from distant matter. It is, therefore, organized by the conditions of energy in the material universe. It, in addition, gains special motions through its own interactions, and impresses these upon the universe. As compared with matter its substance is excessively rare and its motions exces- v sively rapid. Its mobility is therefore extreme, and its sus- _ceptibility to new influences far beyond anything existing in mat- ter. Finally it may be capable of retaining its organization sepa- rate from matter, its constitution being such that the disrupting _ energies which destroy the organization of matter are powerless to affect the psychic organism, they being repelled from its sur- ice, Or passing through it as innocuous vibrations. Under some conditions, and such only, can we comprehend the existence mss = nda And thus only can we conceive the Pee ore es eo ce ee am 4 1885.| The Relations of Mind and Matter. 1157 possibility of the existence of the mind after the disruption of the body, in substance absolutely imperceptible to our senses, yet forming organisms which may be as evident and substantial to each other as are our material bodies to each other, So far all this is pure hypothesis. We have only offered as evidence for the existence of a psychic substance the seeming in- capability of the brain to serve as a mental basis. Yet other evi- dence exists of considerable force and value. We know that a psychic substance must exist for the same reasons that we know an ether exists. We cannot see, touch or weigh either, but there are phenomena in nature which we cannot possibly comprehend without them. We believe in the ether because there are things done in the universe which matter could not possibly do. We may find ourselves forced to believe in a psychic substance for reasons of the same kind. If masses of matter send out radiations of light and heat which affect distant masses of matter, then psychic masses, when actively excited, should send out parallel radiations which will affect other psychic masses, but fail to act upon matter. Evidence of the existence of such a condition is by no means rare. Every mind seems to send out psychic radiations which flow like light rays through ether in every direction, weakening with distance. At least by such a hypothesis we can understand some very remark- able mental phenomena which now stand as incomprehensible mysteries. These we can but briefly glance at. One very com- mon instance of this, which has occurred to most people, is the tendency to think and speak of a person immediately before he appears. Some indication of his coming seems to be in the air, but as an influence that acts not on the senses but directly on the mind. In certain instances persons declare that they can see a mental image of every approaching friend. If our hypothesis be true, it must be that every mind sends out radiations peculiar to itself, as every physical object does, that this peculiarity is recognized by the receptive mind, and consciousness directed thereby to the mental image of the person to whom the emissive mind belongs, precisely as it would if we saw some physical object belonging to that person. : When the emissive mind is actively exercised and is strongly thinking of the receptive person, this influence may be carried to much greater distances, and may rouse the consciousness of the 1158 The Relations of Mind and Matter. [ December, person thought of at thousands of miles away. We shall give, further on, an instance of this kind. The psychic rays may be viewed as preserving the record of their source at any distance, as in the star beams we can read the story of the physical con- stitution of the star, however enormously distant. Another less common phase of this action is the tendency for two persons to speak simultaneously of the same thing. This is of various strength in various cases. One lady tells me that she formerly had a girl for companion in whose presence she did not dare to think of anything she wished kept secret, for the girl was exceedingly apt to speak of anything the instant she had thought of it. The power to make a person turn by fixing a steady gaze upon him is of this same general character. Numerous instances of these more ordinary phases of psychic intercommunication might be adduced, but we shall here mention them only in this brief manner. One thing is evident, even in these phases of the subject, that there are great differences between the emissive and receptive power of different persons. This becomes much more marked in special cases of psychic influence. It may be to some extent, a question of transparency and opacity. We know what very great differences exist in the conductive powers of different sub- stances for electricity. Psychic radiations may find like varia- tions in the physical conditions of different individuals. From one mind they may flow out as through a transparent. In others they may be more or less resisted by the matter of the body. In some cases the resistance may be complete. Reception may pre- sent the same variations, a sensitive or medium being one who is unusually receptive of these vibrations. Such an idea would explain the vigorous mesmeric controlling power of some minds and the ready yielding to mesmeric control of others. And on the principle that nerve currents flow most easily along a familiar channel, we may understand the special rapport between cer- tain operators and sensitives. In this case the body substance of the sensitive has grown specially transparent to the psychic _ emanations of the operator, while it may be more or less ‘opaque to the emanations of other minds. ; As to the evidence of a more decided character than that 3 e of psychic intercommunication, a vast volume of in- ıt be offered. the great sum of these lack the 1885.] Floods, their History and Relations. 1159 essential element of scientific precision of investigation. It will be best, therefore, to confine ourselves to the results attained by the London Society of Psychic Research, since the experiments of this society have been conducted under strict test conditions, and the reputation of its members as working scientists gives a weight of credibility to their testimony. After the elimination of every imaginable source of error, results were attained which seem to prove incontestibly the direct intercommunication, of mind with mind. These results are given in full detail in the published Proceedings of the society, but can be only briefly glanced at here. They consist of what is called thought transfer, mesmeric experiments, phenomena of apparitions and other strange conditions of mental manifestation. In the thought transfer experiments we have striking evidence of the action of mind on mind without the aid of the senses. In these experiments objects, numbers, &c., were named, and draw- ings reproduced with no other guide than the mental concentra- tion of the persons who alone knew the character of the object or drawing. The successful results formed so large a percentage of the whole as to leave chance quite out of the category. There seemed no room for doubt that the thought in the mind of the impressing persons had directly acted on the mind of the sensi- tive, without possible sensory connection. In explanation of these and other phenomena, Messrs. Gurney and Meyers offer a theory of telepathy, or direct communication of mind with mind without sensory aid. But their theory is imperfect in that it lacks the conception of any physical medium of intercommunication as here advocated. (To be continued.) FLOODS, THEIR HISTORY AND RELATIONS. BY WILLIAM HOSEA BALLOU, LOODS vary in their intensity and duration according to their geographical range. There are two great flood ranges ` in the United States lying nearly at right angles, one of duration and the other of intensity. The first is the Mississippi river and its confluents, and the second the Ohio and tributaries. The Mississippi and Missouri rivers lie in a north and south line, and their floods are continuous from early spring until the middle of July, on account of the slow advance of the sun’s heat VOL, XIX—NO. XII. 76 < 1160 Floods, their History and Relations. (December, into the northern mountain and lake sources. While the floods thus formed are never of great height comparatively, yet their long continuation and force are means of most potent destruc- tion. The Ohio flood range is the most terrible on the earth’s sur- face. The water waves generated by it surpass in height, size and power the greatest tidal waves of the ocean. All atmos- pheric destruction by tornado, simoon, whirlwind and water- spout, and all the damage done through subterranean upheavals by volcano and earthquake do not compare with the ravages of the floods of this river. Here is a stream lying nearly parallel with the equator, every portion of which is simultaneously affected by the sun’s heat. When the temperate zone is turned toward the sun in the spring, the Ohio’s ice, its entire drain- age area and all its sources are let loose at once, and a sudden and awful destruction follows. At this time the Ohio is not a tributary of the Mississippi; the latter is its confluent. Its gigantic projectile of water, often 100 feet high, 600 feet broad and 300 miles long, is hurled on its mission of obliteration, sweeping before it cities, towns, forests, farms, levees, live stock, shipping and humanity. When it reaches Cairo it is re-enforced by the gradually forming floods of the Mississippi and Missouri, and there begins its unlocking of gigantic ice gorges which greatly increase its destructiveness. To protect the riparian country from these floods and repair their damages, the United States has expended $500,000,000. The individual losses sus- tained probably amount to twice that sum. There is an intimate connection between floods and business. High floods and low business go hand in hand. The present finan- cial depression was directly precipitated and perhaps caused solely by the last great flood at Cincinnati. That city was then—as in every spring time—largely in debt to New York, Chicago and other commercial centers, for merchandise. Owing to the con- _ dition of the roads and the losses of small riparian and dependent _ towns and cities from the flood, the Southern merchants could = not collect on the products supplied by the North. They were therefore obliged to renew their notes. Then mercantile failures th the | South precipitated a total loss on these notes, and the t era began to spread over the country. A large area soon ceased t to become a market for the North, cut- 1885. ] Floods, their History and Relations. 1161 ting off a part of the business of the latter and projecting a gen- eral stagnation. Capital, which otherwise would have gone South (which at that time was almost the sole region of invest- ment) to aid in its development, was locked up in safe-deposit vaults and Government bonds, causing a bank scare and many bank failures, The depression soon spread to England and other countries. A retrospective glance into American history shows that great Ohio floods and great financial crises have gone hand in hand. It is evident that having spent an entire century in trying, with no lasting effect, to repair damages done by floods, the country should turn its attention exclusively to their prevention. The methods of prevention are simple but expensive. Numerous reservoirs should be constructed among the springs in the hills, and little lakes in which to lock up the water. Great forests should be planted about the sources of the Ohio which will hold snow and ice unmelted for a long period, and allow it to escape slowly. In this way the sun will be made powerless to unloose the entire Ohio flood range at once, and the waters held sub- ject to national control. Congress has considered the question in its usual manner. It overlooked the facts presented above, and empowered the En- gineer department to make surveys at the headwaters of the Mis- sissippi for reservoirs. It might as well have gone to the head- waters of the Ganges, which have about as much to do with the destructive elements of these floods. It dropped $60,000 into this project and then dropped the subject. The future battle is the Ohio, not in Northern Minnesota or the moon. Congress will find it cheaper to purchase the land sources of the Ohio and its confluents, plant them with forests and wall them, than to plaster broken levees. Professor Swing, of Chicago, has suggested that the high mounds of the mound-builders were used as protection against cyclones, He was obviously mistaken. There are no high mounds in cyclonic areas. We find them exclusively in riparian connection, where they were evidently intended for use in time of oods. These mounds were nowhere used to dwell in. None are found with entrances or hollowed out. When opened they either contain skeletons, implements, relics, pottery or nothing at all. Those unoccupied show that the owner fled or was captured 1162 The Problem of the Soaring Bird. [ December, or was slain before his natural death, so that he could not be buried in his own tomb. The high mounds in the valleys served both to protect the dead from floods and as watch-towers in time of danger. One of the remarkable aspects of floods is their influence on the formation of valleys. Nowhere is this more clearly shown than in the valley of the Mississippi below Cairo, over which the floods distribute themselves to a width exceeding forty miles in many places. This valley has a bed of alluvial silt deposited in past flood times increasing from forty feet at Omaha and Dubuque to 300 feet at and below New Orleans. In other words, the flood alluvial deposit of the Mississippi covers 80,000 square miles to an average depth of 170 feet, a surface equal to Montana. In this elastic valley the floods annually work out the destiny of the river’s bed, which is often found miles from its previous course after high water. The ice-gorges which dam up the rivers and hold back the waters for hundreds of miles are another destructive factor of floods. When they break the resulting destruction is enormous. Congress has only to supply its existing snag-boats with dynam- ite in order to destroy these before the damage force is accumu- lated. The Government signal service along the rivers can give warning of their formation. A’. se THE PROBLEM OF THE SOARING BIRD. BY I. LANCASTER. ( Continued from p. 1058, November number.) A® soaring is a phenomenon dependent entirely on bird and air, which are not connected with the earth, to avoid confu- sion it is best to pay no attention to the latter. For instance, a bird motionless in regard to a point on the earth facing a five- ~ mile-per-hour breeze ; the same bird moving in calm air at the ~ Tate of five miles per ee or going with the wind at the rate of _ ten miles per hour, are identical in character so far as soaring is concerned. In each case the wind is meeting the bird at the rate > five spp pei hour, and the differences of translation over the rth a idental, not concerned with the mechanical activities 1885. | The Problem of the Soaring Bird. 1163 A bird resting in a minimum breeze cannot fall to the rear without descending; neither can it rise vértically nor at any angle obliquely to the rear. It can draw forward on the air at any speed, and when the minimum is exceeded, can then fall to the rear, or rise until the minimum is once more reached. At the minimum velocity the bird’s wings are stretched to their ex- treme limit and the angle of inclination is the greatest. As the breeze stiffens, the bird, if it remains in the same place, flexes its pinions and reduces its incline. The frigate bird will float ina storm with not more than one-quarter of its wing surfaces ex- posed. Sometimes it bends the points of its wings downwards until they meet underneath. The positions of the stretched wings in regard to a level with the body of the bird also varies. Those of the frigate bird will average level, the buzzards will be above and the gannets below a level. , For at least three hundred days in the year these birds could be observed in the air, and when the attention was given to their actions for a considerable time, at all seasons, and in the various situations found on so varied a coast as that between Tampa bay and the Capes of Florida, not only the habitual methods common to ordinary soaring flight, but the unusual ones, incidentally per- formed to meet some emergency, were witnessed. The birds also have periodic seasons of feeling which puts them on behavior that in a man would be thought idiotic. The months of Febru- ary and March, the time of breeding, are prolific in these singu- lar air-tumbling performances. They served to emphasize the complete difference between active and fixed wing flight. Being informed by parties from Charlotte’s harbor that sand- hill cranes could be found there, I sat out in search of them. An outside passage of thirty miles was required, which was safely made, and at nightfall I was among the Gasparilla keys. The wind being favorable and the weather fair, 1 kept on the outer beach, and at length drifted through a pass with the swiftly run- ning tide in company with innumerable sharks, porpoises and fish, great and small, all headed for the bay. Rounding the point I threw over the anchor, and enveloped in a blanket with face to- wards the stars, slept, as one who manages a small boat for twenty hours can sleep. About daylight I was awakened by the thump: ing of the mast against the limb of a stunted cedar tree obliquely 1164 The Problem of the Soaring Bird. [ December, jutting from the bank, and while adjusting the trouble a well- known cry sounded far above in the air, which at once banished all desire to sleep. I knew the note quite well. It denoted the arrival of sandhill, or whooping, cranes from the north. Twenty- five years before I had seen them on the western prairies lift themselves on fixed wings above the clouds, and I had no doubt but what the call proceeded from birds which had the evening before been in the region of the great lakes of. our northern boundary. Before sunrise at least fifty had arrived, and were greeted by their comrades on the land in the interior of the key. They came down in great circles from a height of not less than three miles, on tensely stretched wings, until within 200 feet of the earth, when they suddenly began a slow flapping which con- tinued to the ground. I had often seen them begin their migra- tions, but never before witnessed the ending.. They would aver- age a weight of ten pounds, with about eight square feet of wing surface. In rising they slowly beat the air until a suitable eleva- tion is reached, when they assume a fixed position and continue their upward flight in great circles to a high altitude, when they swing off at a tangent for the south. I have never seen one of these birds move its wings after stopping them in its ascent, until they had arrived at the same level in alighting. The buzzards were the best species for observation from the ground. Their patience was simply inexhaustible. I watched a small flock of these birds for fourteen consecutive hours while - they floated in the breeze, waiting my removal from a dead por- poise stranded on the beach. Nothing could surpass the loveli- ness of the day nor the bland freshness of the incoming breeze. The birds would average eight feet in spread of wings, would weigh six pounds, and have about six square feet of wing surface. A memorandum book was filled with notes of the day’s expe- rience. About a score of flaps were made between twelve and three o’clock in the afternoon when the wind was quite active and _ filled with flaws. From four to six in the evening they were as _ motionless as if petrified. As the sun disappeared behind the waters of the Gulf, I ended the hardest day’s work I ever made, and was not fifty feet away before every bird had its beak in the arcass, For several days after this really imprudent exertion of eni ntion Iwas abed, but on resuming the subject determined eriment. pistes: my eyes, assisted by a very good 1885.] The Problem of the Soaring Bird. 1165 glass, several bodies, of six pounds weight each, had remained stationary in free air about thirty feet above the water, absolutely without any visible support. They had remained in that condition many hours, facing a breeze of velocity varying from five to twenty-five miles per hour. In the rear was located my device for determining horizontality of wind, and it was level the entire day. Most people would be less surprised at a body resting in this way in calm air than in wind. They would hold each to be simply impossible, but more mysterious that both gravity and air- resistance should be ignored, than simply gravity. So to deter- mine how much force it would take to keep six pounds in air all the time unsupported, I provided a billet of wood of that weight, well rounded, and proceeded to throw it up in still air, and the moment it came down, catch and return it. The work was hon- estly done; the moment it descended it was tossed back with all the activity I was capable of commanding. I prefer that each one should try this for themselves, and will only say that an hour of such work was far, very far, beyond my muscular capacity. These birds were often watched. from a perch in some lonely tree at the water line. That I could recline at ease in the fragrant foliage of the pine was easily accounted for; the trunk of the sturdy tree antagonized the gravitating force of my body, and I could rest at peace. But what held up the birds? Had gravity ceased to act upon them? Had they no resistance to offer to that sea-born breeze ? After about four years of this kind of work accident favored me. A summer whirlwind, on a calm morning, issued from among the lemon trees straggling over the point a few hundred yards below, and clutching an armful of dead leaves made for the bay obliquely in front of my station in the tree. A pair of buzzards were return- ing from the outer beach on fixed wings, and as luck would have it, were intercepted by the cyclone, and in five seconds were ducked in the waters of the bay. I hope they possessed a sense of humor, but they seemed to blame me for the mishap. A more thoroughly laughable episode I never witnessed, and from the bottom of my heart forgave the creatures for their seeming injustice. They abandoned that part of the coast -but left their secret behind them. For the purposes of this paper enough has now been said as to the facts exhibited, It is very evident that a state of things has 1166 The Problem of the Soaring Bird. [ December, been found to exist which calls for something better than guess- work in way of explanation. Taking the case of a ten-pound bird with tensely stretched and motionless wings, facing a breeze anywhere from two to one hundred miles per hour, and resting serenely over the same spot of earth, without effort and without fatigue, we find our habitual notions about the difficulty of keep- ing unsupported substances in the air at fault. We want a solu- tion of the matter from the standpoint of the mechanical engineer. We need not go into the domain of molecular physics for an- swers, but we wish the bird explained in the same way that a steam-engine is explained when we examine it as a machine doing work. To this end we may ask three questions, and satis- factory answers being found thereto, the phenomenon will be comprehended. I. From whence is derived the motive power to balance gravity ? . 2. From whence is derived the motive power to hold the bird against the wind ? 3. How are these forces applied ? To explain a steam-engine in this same sense but two en tions demand answer. 1, From whence comes the motive power to drive the piston? 2. How is this force applied ? When we say that the force which moves the engine comes from the coal that is burning in the furnace, and is conducted through pipes by the medium of steam to a movable piston which it sets in motion, we have, in a general way, given an explanation to the activities there going on. When we say. that the grind- stone is operated by the force derived from the muscular organi- zation of the boy turning it, then its action is also explained It is in this way that an attempt will be made to explain a soaring bird. No objection is taken to the view that force cannot produce motion, held by some recent scientists. Granted that ee but motion can produce motion, and I am then only con- ce with the sequence of events; with having it understood l that the motion of the piston is not the cause of the burning al, nor that the grindstone turns the boy. I en the eee tornado struck the birds as above related, : iv Wes = on between bird and air were 1885.] The Problem of the Soaring Bird. 1167 thrown into confusion, and the gravitating force of the bird’s mass instantly carried it to the water. It was evident that the internal adjustments to environing conditions, going on through a line of ancestry reaching to the reptiles of the secondary age, omitted summer cyclones. They were too rare to count. It was also pretty clear that the gravity of the bird’s mass was the source of the entire motive power concerned in the act of soaring. Were we dealing with wind-mills, sailing vessels, tornadoes or any other phenomenon in which the air was one factor anda body connected with the earth the other, the force would prop- erly be spoken of as coming from the air. The amount of force would vary with the velocity of the wind. The work done would be referred to the mechanical agency which set the air in motion. But a body suspended in free air is part of the atmosphere, and at rest with it, unless it employs some activity not derived from it. The same mechanical agent which moves the air equally moves the body. The active birds derive the force to move themselves in the air from their muscular efforts, the soaring birds from gravity. Gravity gives a// the motive power; that which antagonizes itself and that which antagonizes air resistance. he case is analogous to that of a man ona moving train of cars. He is at rest with the train throughout unless he employs muscular power to set up motion with it. All activity between man and car is due to the man’s force and not to the train’s force. His force works a pair of legs which set up motion. Gravity works in a different way. It requires a device which compresses air as found in the soaring birds. Notice also that the mechanical action known as “soaring” takes place only between the minimum and maximum velocities with which body and air meet. An initial impulse is required in all cases to carry the body within those limits. In'a calm, the body would have to be pushed on the air until the minimum was reached. Ina breeze it would be forcibly held to reach the same result. The first impulse resembles pushing an engine off of the dead center. It simply starts the machine. It has nothing whatever to do with its continuous running. Once within the limits of “soaring,” the gravitating force of the body gives a lib- eral supply of power for all the purposes of air navigation. Let us suppose the wing surfaces to be twelve inches in width. and the bird to weigh ten pounds, with wing expanse sufficient 1168 The Froblem of the Soaring Bird. [ December, to soar in wind moving at the rate of thirty feet per second hori- zontally. Why does not the body fall? It is true that there is a stiff wind moving against it horizontally, but the gravitating force is vertical and can be in no way influenced by a horizontal force. The ball shot from a level cannon falls precisely as fast as one dropped from the mouth of the gun. It is evident that the body is indifferent to the horizontal air. “This does not act upon it at all. No particle of air influences it but what is in contact with its surface, and the instant it is in contact it ceases to be horizon- tal, being deflected in numberless different directions. In a strict sense, in a sense which alone represents the true character of this phenomenon, the air can only be considered as quiescent in every case of soaring. In every case the air is a dead calm until it comes in actual contact with the body, and the movement of the body on the air is a consequence of force derived from the body and not from the air. It is a parallel case with the boy and grind- stone. From the reciprocal nature of action and reaction, the air is doing as much work on the bird as the latter is on the air. The grindstone is doing as much work on the boy as he is on the grindstone, still it would never do to say that the latter turned the boy. If gravity, then, be the motive power of a soaring bird, how does it act to produce the results? Vertically downwards to- wards the center of the earth precisely as it does in all other cases, and the reason that the body manifesting it does not get lower, is because something is pushing up, against the under sur- face, just hard enough to balance the weight. It may be hard to follow all the peculiarities of the disturbances going on under the bird, but it is certain that they serve to hold it up. They are mainly condensations of air upon which the body is falling, and are equal to ten pounds in each foot of air passing to the rear. _ This ten pounds of force is moving at the rate of thirty feet per: =~- Second, as we assumed at the start, and it follows that an amount capable of holding up 300 pounds each second is passing the rear edge of the bird’s wings and is wasted in falling to the ten- sion of the surrounding air, : Bat this is not all the force of disturbance which passes to the ear. The reactions against air resistance also go there. These, the others, consist in condensations, accelerations and deflec- ig to the: Mr of the composition and EE 1885.] The Problem of the Soaring Bird. T169 of forces they bear the same relation to the vertical disturbances which the height of, the incline bears to the base, or, in other words, they are to each other as the angle of inclination of the resolving planes. Supposing in this case the height to be one- fifth the base, there would be 360 pounds of force passing the rear of the bird’s wing each second. Gravity puts in 300 pounds and gets itself supported in doing it. The weight is thus bal- anced ; but we are employing an external force of sixty pounds to push the body on the air. By the law of the action of elastic fluids under pressure, when the condensed air passes the rear edge of the wing surfaces it expands in all directions, and conse- quently upwards and forwards on that edge. If sixty pounds of the whole 360 expanding is thus thrown forwards, it will balance air resistance, and the total power to produce the soaring phe- nomenon will be the weight of the bird? It only requires one- sixth of the whole force on hand to do it. Ifthis can be utilized by wasting the other five-sixths the task is accomplished. There would be waste in eddies and side currents, so that in reality there would be less than the total force of disturbance passing to the rear. Allowance may be freely made for all wastage and sufficient will remain to perform the desired service. Experiment shows that in very critical tests the result can be attained without the rear expansion. It may be held that each molecule of air as it is struck by the plane is, to some extent, carried with it, as well as condensed, while those below are at rest. Thus a rotary motion may be supposed to take place on the entire lower sur- face, when the air-resistance factor would be neutralized by the excess of gravity in each molecule instead of at the rear edge. It has been objected that this is a disguised form of “ perpetual motion.” Remember that there is a great difference between heaping absurdity on a thing and finding absurdity in it. It is urged that gravity can only do work by the fall of the body man- ifesting it, and that in this case it does not fall; that there is no sacrifice of its energy of position, and hence it cannot do work. This is true of actions in which the earth, or anything fast to or supported by it, is a part, and the gravitating body another part ; and it is true in the sense that the word “fall” means get- ting nearer the earth. But this is not true with soaring nor with allied phenomena, and I will illustrate the matter by an example. Suppose that our hypothetical bird rests in the air in a horizontal é 1170 The Problem of the Soaring Bird. { December, position and that the wind moves vertically upwards against it at the rate of twenty feet per second. To get the attention on the significant features of the case, we will suppose the bird to weigh : the same as the air which it displaces, thus obliterating the gravity factor. It will then have no motion with respect to the air, but will move with it. In this condition it is not a falling body, and is doing no work. It is simply a body resting motion- less in air. We will now suppose ten pounds of weight to be added to it. It instantly becomes a gravitating body doing work on the air, Its motion is accelerated until a velocity is reached at which the work done on the air is equal to the force doing it, when its motion becomes uniform. Suppose this to be twenty feet per second. What have we? A case precisely analogous to that of a soaring bird, which is a falling body doing work on the air without losing its energy of position. Its “fall” is prop- erly related, in a strictly scientific sense, to that upon which it is moving, and upon which it is doing work. In relation to the ` earth, or the moon, or the seven stars it may be at rest, as they are not even remotely concerned in the matter. A soaring bird may therefore be considered a machine for dis- turbing air. The motive power required for driving the mechan- ism is its gravitating force. Its effectiveness consists in the amount of disturbance which returns to the normal condition of the surrounding atmosphere. ; There are two peculiarities connected with its action, which may be considered accidental or rather incidental, which deserve attention, for they are of the first importance in all questions relating to artificial air navigation. One of them is, that the ma- ‘ terial upon which the machine does work becomes the frame which supports it, and which is not connected with the earth in any way. The other is, that while the motion of the device is in all cases in two directions on the air upon which it operates, viz., in the direction of the gravitating force and at right angles to it, ~ inrespect to the earth’s surface its motion is in any direction what- _ ever indifferently. These two unique characteristics of soaring Constitute its value for artifical use. They are the results of the 2 ctio n of an inclined plane driven on air, and meet the require- ments of atmospheric translation completely, so far as the direc- n of mee and supply of motive power is concerned. It es ~ balloons to antagonize gravity, and of 1885. | The Problem of the Soaring Bird. 1171 motors to drive the machine against the air. Two requirements are still needed. The device must be steered and kept in posi- tion. When it is remembered that the rear expansion drives the bird forward, any change in the extent or position of one wing which is not shared by the other would retard or accelerate the motion of the changed side relatively to the other, and serve to determine the direction of motion. A balance still needs to be preserved. The bird gives significant hints here also. The heavier it is the steadier is its motion, and a device large enough to sustain the weight of.a man may be qualified by its inertia to assist in preserving its own equipoise. The most important points of this subject have now been given. Experiments with artificially induced currents of air, requiring a steam-engine to be transported to the sands of Flor- ida, were expensive and productive of only negative results. Much time and means were wasted in this way, and all my efforts previous to the summer cyclone above recited seemed abortive, excepting in the settlement of the facts of soaring as shown by the birds. The moment the idea that gravity was the motive power and not the air, was entertained, the whole matter became luminous. No steps subsequently taken have been in the wrong direction, and I shall return to the prosecution of the subject the moment prudence permits. The relation of the soaring birds to artificial air-navigation fills the whole subject with a sort of pathos. A turkey-buzzard, most despised of all the birds, employs mechanical activities by using a device of such simplicity that compared to it a common grind- stone is a complex machine, for the purposes of air-locomotion in the search for carrion, with conspicuous and complete success, itself being a working model of the very thing which man has worked, and sweated, and died to possess, and he has never seen it! For a period of time coéval with his own existence on this planet this thing has been going on, and the world is full of it now, and still the mature conviction of both common sense and science is, that it is impossible. 1172 The “Collar Bone” in the Mammalia. [{December, ‘THE SIGNIFICANCE OF THE “COLLAR BONE” IN . THE MAMMALIA. BY SPENCER TROTTER, M.D. HEN running through a series of forms in animal life a structure is found fully developed in some and in others rudimentary or entirely wanting, we are led to consider the causes acting upon the structure through the life of the animal which has brought about the condition of development or non- ‘development present. Every fully developed tissue in an organ- ism is needed or it would not be there; and just so soon as by increasing change in life and habits, it becomes a factor of less and less importance to the animal; it fails more and more to attain its former standard of development, and in time falls back to the primitive condition from which it arose and finally dis- appears. The “collar bone,” or clavicle is an unstable factor in the shoulder girdle; by this I mean an element not always found present throughout vertebrates, and its presence, absence or rudi- mentary condition, is in relation to the life of the animal. In this article it is my intention to note, principally among the mammals, the relation which the clavicle bears to the various modes of life, but before taking up the consideration of individ- ual forms, reviewing briefly the general anatomy of the part. The shoulder girdle consists first of the scapula, or “ shoulder blade,” a more or less irregular plate of bone preformed in car- tilage and ossifying from two centers, the dorsal or scapular, the ventral or coracoid, in position against the anterior thoracic ribs, its long axis varying in inclination. Its ventral end terminates in the “ glenoid cavity,” a ridge and process, spinous and acromion, on its outer surface are more of less developed in different forms, and in all mammals above _ the Ornithodelphia the coracoid is reduced to a mere process. Second, the clavicle, when present, preformed in fibrous tissue extends as a bar of bone from the acromion process above the -~ glenoid cavity to the manubrium sterni, forming a strong support to the girdle and an extended surface for ligamentous and mus- cular attachments. Mechanically considered the shoulder girdle (by using the term “ girdle” both sides of the body are implied) nothing more than the fulcrum of which the fore limb is the of of the aed kind, and its specialization is in direct relation 1885.] The “Collar Bone” in the Mammalia. 1173 to the amount and character of the work done. The clavicle first appears in the ganoid fishes as a secondary apparatus devel- oped in connection with the primary cartilaginous scapular arch. In the teleost or bony fishes it becomes a more important element in the shoulder girdle, having connection with the skull and the opposite sides joining in the ventral median line. It undergoes a reduction and becomes of less significance in Amphibia and Reptilia, but in birds it assumes an important position in relation to flight, the entire shoulder girdle in fact being specialized to meet the conditions incident to aérial loco- motion. The coracoids—large, strong bones—act as braces ; the clavicles, peculiarly modified, are united at their sternal ends into one bone, the furculum, or “ merry thought,” which, as Owen has pointed out, acts as an elastic, bony arch opposing the force inci- dent upon the downward stroke of the wing in flight, thus aiding the humeri, or arm bones, to regain their former position in the succeeding upward or counter stroke with as little loss of time and energy as possible. In terrestrial forms (grouse, fowls, etc.), where flight is sustained for short intervals only, the arch is nar- rower and the structure more slender and delicate. Taking up the Mammalia with a view to ascertaining the rela- tionship existing between the development of the clavicles and the work done by the fore limbs, let us start with the following general proposition as a basis for our observations, namely, that those animals which have the fore limbs specialized over the hind limbs in relation to work, possess a clavicle, and where the hind limbs are the most highly specialized, the clavicles are rudiment- ary or entirely wanting. Leaving the ornithodelph mammals (the Australian duck-bill, © Echidna, etc.), with their bird-like shoulder girdle, we note the presence of more or less well developed clavicles in all the mar- supials, with the single exception of the “ bandicoots” (Pera- melidz), where it is wanting, and its absence may be accounted for from the fact that the bandicoots from their terrestrial mode of life, nesting in hollow places and feeding on insects, roots etc., have for along time had their fore limbs subjected to less complex conditions than the arboreal and predatory families, the opossums (Didelphide), the Dasyuride, the phalangers (Phalang- istidæ) and the kangaroos (Macropodidz), which constitute the rest of the order. In the kangaroos the clavicles, though pres- 1174 The “Collar Bone” in the Mammalia. (December, ent, are slender and delicate, the weak fore limbs coming into use in manipulating the “pouch,” etc., thus throwing a variety of motion into the shoulder joint, which explains the presence of clavicles in an animal whose locomotion is almost entirely per- formed by the hind limbs. Among the Insectivora, a large order of wide geographical range and rather uniform life, the majority of species being ter- restrial and fossorial or burrowing, we have the clavicles well developed with but one exception, that of Potamogale velox, a rare form from Western Africa, and this is the only insectivore which is almost entirely aquatic. It measures about two feet in length with a long cylindrical body, tapering continuously into a thin, laterally compressed tail, which is the main propulsive power when swimming, the short legs with their unwebbed feet drifting back against the body. Another form, Myogale,.from the streams _of Southeastern Russia, is natatorial and possesses a clavicle, but the feet are all webbed and come into play along with the tail as organs of propulsion. The moles, Talpidæ, are eminently fossorial, their excavations being everywhere known; an East Indian squirrel-like form is arboreal ; all the rest are terrestrial and fossorial. The phe Edentata is divided into two primary groups, the “leaf-eaters”” (Phytophaga) and the “ insect-eaters ” (Entomoph- aga). The P Phytophaga comprise the “ sloths,” curious, arboreal forms inhabiting the South American forests, represented by only two living genera ; they are entirely arboreal, making character- istic progression among the tree-tops on the leaves of which they feed. In the two-toed sloth, or “ nnau ” (Cholcepus), the clavi- cles are well developed ; in the “ai,” or three-toed variety (Brady- pus), they are small, rudimentary, having lost their sternal attach- ments and evidently undergoing a retrogressive change, due probably to some variation in the animalľ’s life and habits which brings the part into less active use. In the Entomophaga (ant-eaters, armadillos, a we find the 7 Fiaeicies fully developed in the climbing two-toed ant-eater Cy- hurus, a small South American species; also in the Cape ant- a ester, or “aard-vark,” Orycteropus, a burrowing form from the ae of Good Hope; while in the great ant-eater, Myrme- phaga, a strictly terrestrial form but not fossorial, the clavicles t, m ae ens open the ant hills and termites’ 1885.] The “Collar Bone” in the Mammatia. 1175 mounds, and the narrow, flexible tongue securing the food, stand in place of the burrowing habit, thus bringing the shoulder joint under much less active conditions. In the South American armadillos, which are mote omnivorous and are “ diggers,” the clavicles are developed. The “ pangolins,” scaly covered ani- mals, mainly terrestrial and rolling themselves in a ball on the approach ôf danger, have no clavicles. In the order Rodentia we find all the Sciuromorph group with fully developed clavicles ; the squirrels are either arboreal or bur- rowers; the marmots, Arctomyine, are typical burrowers, while the beaver, though eminently aquatic, brings the fore limbs into active use in the construction of its dams and lodges. The Myomorpha (rats, mice, gophers, etc., typical gnawers and diggers) have well developed clavicles, the gnawing habit bringing the fore limbs and shoulder girdle actively into use to steady the head and neck and the object which is being worked upon. _ In the Hystricomorpha (porcupines, cavies, etc.) clavicles are found developed in the climbing tree-porcupines (Sphingurinz), of which our Canadian species (Erethizon) is a member, and absent in the large African porcupine and all others of the Hystricine group, which is strictly terrestrial but not fossorial. The chinchillas have well developed clavicles, the horse-trip- ping burrows of the “ Pampas Viscacha” being too well known to the riders of that region. The agoutis (Dasyproctidz), inhab- iting the banks of streams in the South American forests, semi- aquatic and sub-ungulate (¢. e., having the feet partially encased in a horny sheath or hoof) have rudimentary clavicles. The | Caviide (guinea pigs) and the “capybara,” the largest living rodent, semi-aquatic, with webbed. feet, have imperfect clavicles, « The Lagomorpha consists of two living families, the Lagomyi- dz, small burrowing animals called “picas,” inhabiting Alpine regions, and the Leporidz (hares and rabbits) ; the former family having well developed, the latter rudimentary clavicles. The hares are typical runners, solitary, never burrowing, depending for safety in speed and making their characteristic “form”; the species known as the rabbit, however, differs largely in habits _ from the other members of the family, being more or less gre- garious, living in “ warrens” which it burrows out, and having much less capacity for speed. Clavicles are developed in both; VOL. XIX.—NO. XIT, 77 1176 The “Collar Bone” in the Mammalia. (December, very rudimentary in the hares, and in the rabbits existing as a bone incomplete at the ends, a condition which we would expect to find from the variation in life habits. Taking up the large order of “ hoofed” animals, the Ungulata, we note the complete absence of the clavicles in all the forms, not a vestige of the bony structure being found in any one of them. They are the “runners” par excellance, and if we may use the expression, ive on their legs, the capacity for speed and endurance being one of the chief factors aimed at by natural selection in maintaining and perfecting the species. Here we find the fore limbs subserving the hind limbs in rela- tion to work; the latter are the main motor power in running, while the fore limbs act chiefly as supporters and guiders; hence the entire absence of clavicles. The marine Mammalia, with their rudimentary limbs, have no clavicles. In the flesh-eating animals, Carnivora, the clavicles are always rudimentary, and in many cases entirely wanting. They are bet- ter developed in the cats, Felidz, than in any other family of the order (though the articular extremities of the bone are lost), for the clutch which follows the spring in securing their prey, brings the fore limbs into more active use than in the dogs and wolves, Canide, which run their quarry to “ the death,” and then pull it down by force of numbers. Many of the cats, too, frequent trees, but they spring from place to place and do not properly climb. Several species of bears also climb, but the habit is more acquired than natural, the fore limbs clasp the trunk while the hind ones secure a foothold and, so to speak, shove the ani- mal upward, very different from the active movements of a nat- ural climber. In the bats, Chiroptera, as we would expect from their mode of life, the anterior limbs being the main factors in their flight, clavicles are rappr long, curved and strong. The arboreal Lemurs also have them developed. In the order Primates we have the clavicles present in all, from ` arboreal monkeys up through the anthropoid apes to man, were the anterior limbs attain such perfection, with ball and The badger (Taxidea) is a striking exception to the general rule, being an emi- F imal yet devoid of clavicles.

After this brief survey, and with the forementioned proposition in view, viz., the correlation existing between the development of the clavicle and the work done by the fore limbs, we are left to draw the rational conclusion that the subject under consideration is one of use and disuse of parts, as Darwin has so clearly pointed out in his chapter on rudimentary organs in the Origin of Spe- cies. The facts we have noted in our hasty glance at the Mam- malia confirm this, in the more or less perfect development of clavicles in arboreal, fossorial, aérial and all other forms where the fore limbs are the active, aggressive pair in the life of the animal, and their absence or rudimentary condition in the hoofed animals, the marine species and all others where the anterior pair take a secondary place in the work done by the limbs. As there is, of course, no actual disuse of a part as a whole (the nearest approach to this being in marine forms), a simple, uncomplicated motion existing, with little strain at the shoulder joint, the parts require less support and fewer points for ligament- ous and muscular attachment than where the movements are more complicated and the strain more severe. Consequently we have a greater or less differentiation in the elements of the shoul- der girdle as the case may be, and the clavicle, holding as it does a position of secondary importance, is the unstable, variable ele- ment. A’. Ve PEAR BLIGHT AND ITS CAUSE. BY J. C. ARTHUR. EAR trees in this country are subject to an endemic disease that, owing to its malignancy and frequent occurrence, is well . known to cultivators and fairly well discriminated by them. It is known both as pear blight and fire blight, and the same disease in the apple and quince is also called twig blight. The term blight ‘is applied to many kinds of plant diseases, and especially to those — that eventually kill without rendering the cause conspicuous; it is also the name of a class of disease-producing fungi. The pear malady bearing this name is, however, a specific disease, although 1178 Pear Blight and its Cause. [ December, it would be a matter of considerable difficulty to describe it in such diagnostic terms that the reader would recognize it under all conditions and avoid confounding it with the numerous other blights and incidental maladies which resemble it. Its most characteristic feature, if one considers only pomaceous trees, such as the pear, apple, quince, crab, hawthorn, etc., is the complete dying of the branches subsequent to the appearance of the foli- age without obvious cause and usually with apparent suddenness. This involves the limb and its leaves, both of which turn blackish and usually exhale a peculiar but not very strong odor. From the softer stems there often exudes a viscid, whitish substance forming small drops on the surface of the bark and finally becom- ing hard like an exudation of gum. The blackening of the dying branches does not differ from that produced by death from other causes; hence arises the danger of mistaking other injuries of the tree for the true blight as here understood. Death may be brought about by the limb being partly broken off, or it may be punctured and killed by the pear- blight beetle (Xyleborus pyri), a very small insect which often escapes detection, or it may result from other mechanical injuries. There is also the blackening of the ends of young twigs in spring known as frozen-sap blight, the blackening of the edges of the leaves later in the season, more common on some varieties, 2. £., the Sheldon, than on others, and so on. But the real blight kills the limb in advance of the leaves, and will usually show the blackened bark, when raised with a knife, below the lowest dead leaves; the gummy exudation, when that is to be found, is abun- dant confirmation. In addition to this, the extent of the malady, sometimes embracing the larger part of the tree and most of the trees of the orchard, assures one of its identity. Pear leaves may at times assume a deeply bronzed appearance and the bark be- come dark colored, but these appearances need never be mistaken e _ for blight, as the tissues beneath will be found normally green _ The disease is most observed during July and August.

Some- times a whole tree is killed, but usually only certain limbs die, which if early removed will leave the remainder of the tree in normal condition. The progress of the disease along the limb is variable, but in general is greatest during the hottest weather ; in winter it moves slowly, even advancing but six to twelve inches during a whole cold season. The advent of spring, quite con- trary to what one would expect, usually checks the disease after it has defied the rigors of winter, and by the time the tree is well clothed with leaves is brought to an end, not to be again revived. ` So extensive and prominent a disease of an important fruit tree, and one entailing heavy pecuniary losses during epidemic years, has naturally been the occasion of much discussion. Its cause being obscure and the manner of its incursions and spread mysterious, it was variously ascribed to the soil, the weather, the electrical influences of thunder storms, to undiscovered fungi, p and many other agents. These attempts at explanation were all unsatisfactory, failing to account for many of the phenomena connected with the disease. The first substantial advance toward a solution of the question was made by Dr. T. J. Burrill in his memorable announcement in 1880 to the American Association for the Advancement of Sci- ence that he had discovered bacteria in invariable connection with the disease. The same discovery was reiterated by the author in an article in this magazine for July, 1881. He also proved that the disease is infectious and may be communicated to healthy limbs by inoculation, using the gummy exudation as T a virus either with or without dilution with water, and not only x to pears but to apples and quinces as well. No additional discoveries of note were made till the investiga- tion, which is still continued, was taken up by the writer in July, 1884. The subject need not be further treated chronologically, as a clearer and more concise statement can be made by giving - the present condition of our knowledge irrespective of the order of its acquisition. The term bacteria is a generic one, and covers many forms ex- hibiting great morphological and physiological differences. The form causing pear blight does not belong to the genus Bacterium, as one might infer, but to the genus Micrococcus, and bears the 1180 Pear Blight and its Cause. [December, full name of M. amyhovorus Burrill. Members of this genus are globular, or somewhat longer than broad, either single or in short chains of a few individuals ; they multiply by a transverse division, each half growing to the size of the original from which it was derived, and finally becoming an independent cell. The formation of spores does not occur, or at least has not been dis- covered, in this genus; no transformation takes place. The pear blight Micrococcus is oval in outline and measures 1 by 1%», which is .o0004 by .00006 inch. This is extremely small, so smail, in fact, that it would take more than a thousand placed end to end to reach around the period at the close of this line. They are considerably smaller than the bacteria of common - putrefaction (Bacterium termo), the hay bacteria (Bacillus subtilis) which usually appear in all sorts of vegetable infusions, and many others. On the other hand they are by no means so small as the germs of diphtheria (Streptococcus aiphtheriticus), of small- pox (S. vaccine), and others. When in active growth they are single or attached to each other in pairs, dumb-bell form; when _ growing more slowly there is a larger proportion of the dumb- bells, and in addition chains of four to six cells each. Although these bacteria are very small, yet there is no diffi- culty in demonstrating them in the tissues of the pear tree on account of their extraordinary abundance. The slightest frag- ment taken in midsummer from a blighted pear limb and placed in a drop of water will readily enough show the presence of bac- teria to the unaided eye by the white cloud of them which spreads from the bit of wood throughout the water. Slice up some blighted wood into a small quantity of water and it will be ren- dered milky by the enormous outpouring of the bacteria. Under the microscope these are found to be all of one kind, and not in- _ termixed with ordinary putrefactive or other bacteria, a circum- _ stance which may yet be turned to account in studying problems -~ _ in which an admixture of forms is detrimental. The exudation already referred to is found by the microscope to be composed _ solely of blight bacteria and a soluble substance which holds m together. ~ ien in very vigorous growth the blight bacteria are active, present an animated appearance under the microscope, but ily pe molecular movement common to all fluid. Their progress rough the 1885.] Pear Blight and its Cause. 1181 plant is doubtless largely due to simple displacement as multipli- cation takes place, although aided by the limited activity of the organism and the movement of the sap. The change induced in the tissues of the tree partakes of the nature of a true fermentation. That we do not have to do with a putrefactive change is patent enough, as no offensive odor is given off. The disengagement of carbon dioxide may be made evident by partially filling a test tube with fragments of a freshly blighted limb and adding water enough to little more than cover them. In a short time bubbles of gas will be set free, and a drop of lime water held in the tube will show the presence of carbon dioxide by the whitening of its surface. It is not so easy to determine the nature of the other products formed. Careful and repeated tests give no indication of the occurrence of butyric acid. The presence of alcohol in very slight amount was shown by means of the delicate iodoform test. For this a nearly full- grown Bartlett pear, which was thoroughly permeated with the blight bacteria from an inoculation made a week before, but the tissues still undiscolored, was distilled and the distillate used for the test. The amount of alcohol found was so slight, however, requiring a microscope to find the crystals produced by the test, that it did not account for the main bulk of the product of the organism’s activity. This product is presumed to be mainly gum of some sort, for the following reasons, tnter alia: the solubility, adhesiveness, taste or rather tastelessness and the appearance upon drying. There is much probability, indeed, that this be- longs to the viscid fermentations, which have been but little inves- tigated. The bacteria in the tree first attack the starch of the cells, then the cellulose of the cell walls, and finally the whole tissue be- comes a liquid mass. When, however, the cell walls consist of lignin or other secondary substances they are not broken down, The action on the cell wall is best seen in the tender, unmodified tissues of the fruit. After this survey of the characteristics of the organism and the chemical changes which it induces, it will be profitable to learn something of the nature of the disease itself. The usual impres- sion has been that the disease is like a blast of superheated air _ passing over an orchard, leaving dead and blackened foliage in its track, or that it appears suddenly as the result of a thunder 1182 Pear Blight and its Cause. [ December, storm following hot and damp weather. Its true nature, so differ- ent from these conceptions, has been learned by inoculating healthy limbs with germs from an affected tree and closely watching the progress of the disease through its whole course: from inception to the death of the limb. The inoculation is made by puncturing the limb and applying some of the gummy exuda- tion, or, better, a drop from a watery solution of it, or from water in which some diseased tissue has been sliced. If this be done in July and the inoculation be made in a young and tender shoot, the tissues near the wound will show discoloration in about a week, and in the course of a-week longer the leaves and end of the shoot become blackened and dead. Let it be noticed that at the most favorable season for development it requires some two weeks from the time of the attack to enable the disease to gather sufficient headway to be conspicuous; for no observer is likely to detect the change in the color of the bark before the dying leaves have fixed his attention, unless he knows an artificial inoc- ulation has been performed. This sufficiently disposes of the supposition that the disease is sudden in its action; still more marked proof will be adduced later, showing that in natural course it is slower yet. Over two hundred recorded inoculations have been made, and from these we learn that the disease makes the most rapid progress in the newest and most succulent tissues ; and the nearer to a vigorously growing bud an inoculation is made, the more likely it is to succeed. In fact, it was soon found that no result was likely to follow an inoculation in wood a year or more old. This suggested the inoculation of growing fruit; the results were most surprising, for the tender parenchy- matous tissues were entirely broken down into a creamy fluid, -which now and then escaped at the wound made in inoculating and dripped upon the ground. | Repeated. attempts to convey dhe doere by lnpculating the , eaves resulted in failure, except a partial success when very young leaves were tried. It is noticeable that the leaves are the ast to succumb to the disease; they will remain green for days or € en weeks after the bark at that point has become brown and sad. Bacteria cannot be found swarming in the leaves as in the ad wood; the conditions do not seem favorable for their The c clusion i is inevitable that the death of the ranch is chiefly due to the cutting off of 1885.] Pear Blight and its Cause. 1183 The investigations of Professor Burrill showed that the disease might be conveyed to the apple and quince trees also. Not only ` was this easily confirmed, but inoculations were successfully per- formed on the English hawthorn (Crategus oxyacantha), the evergreen thorn (C. pyracantha), and the service berry (Amedan- chier canadensis), while they failed on grape, raspberry, mulberry, peach, etc.; that is, they succeeded on members of the pear family, but not on other plants. The virus was from the pear, apple and quince, interchangeably, and showing no perceptible difference in the results that could be traced to the kind of virus used. The only differences to be noted were such as were obvi- ously accounted for by the varying ripeness and solidity of the tissues. Unsuccessful inoculation was made upon the mountain ash (Pyrus aucuparia), but as the tissues were already solid when done, and as branches suffering with the disease have since been found, there is no doubt that it can be communicated if the inoc- ulation be properly performed. In the studies so far detailed the germs were artificially intro- duced into the branch; the problem of how they gain entrance naturally seemed for a time well nigh unsolvable. Virus smeared upon the outside of the branch, leaf or fruit had no effect ; dis- eased branches tied among healthy ones under the most favora- ble circumstances for contagion gave no results; apparatus ar- ranged to draw air across diseased branches upon healthy ones also failed; copiously watering a potted pear tree for a month ‘with water white with blight bacteria had no deleterious action - on the tree; and yet the germs must gain entrance some way, for it is inconceivable that they should originate spontaneously within the tree.. Finally some light was secured by a series of partially successful experiments in which water containing blight ‘bacteria was arranged to drip upon pear and apple twigs; the germs entered the twigs through the moist surface of the young- est tissues. A fortuitous observation now made the matter clear : it was noticed toward the end of June that the English haw- thorns, which blossom very freely about the middle of May, were seriously affected with blight. At the time of observation the flowers had long ‘since disappeared and the fruit was well ad- vanced toward maturity. The blighted branches, however, were still crowned with dead flowers, and wherever the dead spur or branch was not terminated with a truss of flowers it showed’ ` 1184 | Pear Blight and its Cause. [ December, every evidence of having been arrested in the midst of rapid growth. The conviction was established that the germs enter the tree in spring through the moist glandular surfaces within the flower or the tender surfaces of expanding buds, but that the disease does not make sufficient progress to become conspicuous till the warm days of June or July. As the flowers drop and the branches cease extending less and less chance exists for the tree to take the disease. Insects may now and then transfer the germs, for two pears were found the present season filled with blight, in both cases showing the point of entrance, evidently a puncture made by an insect. It is only in some such exceptional way that the germs can gain admittance through the well pro- _ tected surface of fruit. If the germs pass from the air into the tree, in what manner do they get out into the air again at the proper time for the next season's attack ? Manifestly the bacteria within the tree are se- curely imprisoned by the bark, which as effectually prevents their escape as it does their entrance; and at any rate, in spring, the time for attack, there are few bacteria left alive in the tree. Limbs with tender tissues exude great numbers of germs during July and August, but so agglutinated that the air cannot dislodge them, until the rains have washed them to the ground and dissolv- ed the gum which binds them together. The query now presents itself whether the germs may not be able to thrive outside the tree. To test this, cultures were tried in various media, and it was found that infusions of hay, corn meal, starch and various other vegetable substances make a nutritive fluid in which the . _ blight bacteria flourished in varying degrees, no matter whether the solutions were acid, alkaline or neutral. When transferred from the culture fluid to the tissues of the tree, the usual form of blight follows. This plainly indicates that the germs washed from the tree by rain may find congenial nidus among vegetable — refuse, thrive and multiply, pass the winter, for cold does not i injure them, even pass an unfavorable year or two, and at times : ; swept into the air be brought by gentle rains or an arrest- of dew into contact with the delicate surfaces of expand- ot or flower and infection be secured. hay g shown the | progress of the disease to be coordinat- Le ent of germs and traced the life cycle of the still persons who do not believe that hi 1885.] Pear Blight and its Cause. 1185 germs cause the disease, but that they are merely accompaniments of it. To meetthis objection, and place the subject upon a logical and irrefragible basis it is necessary to state the results of still further studies. In order to determine whether other bacteria will grow under the same circumstances, various kinds were in- oculated into pear trees—bacteria from rotting spots in green tomatoes, from various sorts of putrefactions, those which had incidentally appeared in various culture experiments—and uni- formly with negative results. When inoculation was made from a culture of blight bacteria contaminated with other forms, the resulting blight contained but the one sort. It is a well-known fact that most bacteria will not thrive in acid solutions, and Hartig has supposed that the reason that plants are so free from parasitic bacteria (only two, or at the most three, true vegetable parasites being known among them) is that they cannot withstand the acidity of the sap. Be this as it may, only one form of bac- teria has yet been found to accompany pear blight. But this does not dispose of the possibility that the blight is not caused by the bacteria, but by some deleterious substance which goes with them or which they produce. It is obvious that as the blight may be produced by using a drop of water which has been flowed over blighted tissues, the active agent must be either the bacteria or the substances which the water dissolves. . There is a very simple way of separating solutions from bacteria by filtering through porous earthenware, which permits the fluid to pass, but not the bacteria. It has been demonstrated by trial that inoculating from a filtrate prepared in this way will not pro- duce the blight. Separating the bacteria from all accompanying substances is accomplished by means of fractional cultures. Such a drop as used for inoculating is introduced into a suitable steri- lized culture fluid; after some days, when the bacteria have well filled it, a drop is removed and used to start another culture, and so on. In this way the bacteria are kept vigorous by growth and multiplication, and the unvitalized substances which accompanied them in the first drop are more and more diluted at each transfer. Finally a drop from the last culture of the series, in which the amount of substance derived from the original drop must be so infinitesimally small as to be inoperative, is used to inoculate with again. Carefully conducted experiments of this kind have given as severe blight as in direct inoculation. No stronger proof is needed that the bacteria are solely responsible for the disease, 1186 | Editors’ Table. [ December, EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. There is little difference of- opinion among the scientific men of this country as to the great value of Government aid to scientific research. Not only is its importance obvious to them as craftsmen, but as citizens. It is not worth while to make nice theoretical distinctions between State and United States rights in this matter, for the great point is to secure, in the language of Smithson of illustrious memory, “the increase and diffusion of knowledge among men,” and especially the men of this country. If the State governments are too indifferent to their own interests to foster the work, let the General Government sustain it. Its utility is two-fold, The one object which is alway obvious, is the ex- ploration and exposition of the resources of the country. The other, no less important, but less understood, is the development and occupation of the intellectual force, activity and thought of the men of the country. The cultivation of man is the most important of human enterprises, and a republican form of govern- ment rests on a basis of such cultivation. The government aid to the universities of Germany is one of the principal assurances of progressive, or even continued, civilization which the world possesses. As the Government of the United States does not aid the universities of the country, it should not fail to sustain and develop its own system, which embraces the various scientific bureaus at Washington. - It has sometimes been objected that the great power of the Government treasury constitutes it such a rival, as to seriously discourage private enterprise in this direction. There are two” reasons why this reasoning is fallacious. First, the field of sci- ence is so vast that no organization can cover it; there is always room for workers, especially at the top. Second, brains are not produced by money, and ideas are not for sale on demand. The _ thinker who produces ideas on $1500 a year, will only be too _ glad to have some one in Government employ to illustrate them with, larger resources. Moreover there are some departments of tific work in which the Government can have few or no These are the — enterprises which eee per- 1885. ] Editors’ Table. 1187 also excavations for fossils on any but a limited scale. The crea- tion and support of scientific museums and laboratories must have the assistance of a heavy purse; and finally, governments have generally been the only medium of publication of results on any considerable scale. Official science has, however, no shield of Achilles which shall protect her from the usual temptations of power and from the methods of politics. It is true that she more surely stands or falls on her merits than any other representative of human labor, yet as she is the teacher of mankind, who is to decide the ques- tion of merit? That she may become corrupted, so that the love of fame and power may supplant the love of knowledge, is not impossible, The man of politics can see and understand this, and whether true or not, charges against scientific men holding official position will be preferred, as in the case of other office- holders. The public press has on various recent occasions applied the term “ political scientist,” and has attempted to point out per- sons to whom the expression is appropriate. Although a “ politi- cal scientist” is a conceivable person, the applications made by the newspapers have been wide of the mark. The term is not appropriate to a man because he secures large or small appropria- tions from Congress to be expended on scientific work. All honor to such men, whoever they are. Their country and the world owe them gratitude, not sneers. . If we were to seek to define a “ political scientist ” we would de- scribe him as a man who sought the aid of the resources of the Government to hold an office for its emoluments or honors to which his abilities and services to science do not entitle him. In order to do this he will reproduce the ideas of others without ac- knowledgment ; he will endeavor, through means well known to men in official position, to suppress criticism of his work, and thus to reach an eminence of popular reputation which is purely facti- tious. Such would bea man who might appear to fulfill the duties of his position by the employment of persons to do his scientific work for him. A “political scientist ” would spend little time in his study, and a great deal of time with prominent persons of all kinds, gaining the “influence” that comes from personal repre- sentations in the many quarters where the merits of questions of science are unknown. The “ political scientist” might flourish for a time in this country, and his existence would be a constant menace to the prosperity of Government scientific enterprises, and would react disastrously on the men of real merit. —— The Legislature of Michigan has done itself discredit in the treatment of the last Geological Survey of that State.

ROMANES’ RESEARCHES ON THE Nervous SYSTEMS OF JELLY AND StTar-FIsH.'—The beautiful researches and discovery by Haeckel of a nervous system in Geryonia, consisting of true ganglion cells and true nerve-fibers, and the extension by the Hertwig brothers of our knowledge of the nervous system of Medusz in general, especially the naked-eyed forms, marked a most important step in animal morphology. These microscopical observations were, except Haeckel’s dis- covery, forestalled by the physiological experiments of Professor Eimer and Dr. Romanes, who, however, worked independently of each other. In the present work Dr. Romanes gives a popu- lar account of his own researches, with due mention of and credit to Dr. Eimer’s researches in the same direction. After having some account of the structure of the Medusz, we are afforded the results of fundamental experiments. The author proved that excision of the extreme margin of a nectocalyx (or umbrella) of the naked-eyed Medusz causes immediate, total and permanent paralysis of the entire organ. This result is striking and decided. Indeed, adds the author, “I do not know of any case in the animal kingdom where the removal of a center of | muscular system, there being no subsequent movements or _ twitchings of a reflex kind to disturb the absolute quiescence of _ the mutilated organism. The experiment is particularly beauti- ful if performed on Sarsia; for the members of this genus being- remarkably active, the death-like stillness which results from the 1885. ] Recent Literature, 1189 vast majority of cases it was found that excision of the margin impairs or destroys the spontaneity of the animal for a time, the paralysis so produced was very seldom permanent, After a vari- able period occasional contractions are usually given, and in some cases they were resumed with but little apparent detriment. Light was found a most marked and unfailing stimulus, and light ger se, rather than a sudden transition from darkness to light. Hence it was satisfactorily proved that the “eyes” of these animals are really such, as the following experiment with others, proves: “ Having put two or three hundred Sarsiz into a large bell jar, I completely shut out the daylight from the room in which the SAN D GAL) ae) Aves RAMAN Aisne” Fic. 1.—Aurelia aurita. jar was placed. By means of a dark lantern and a concentrating lens, I then cast a beam of light through the water in which the Sarsiz were swimming. The effect upon the latter was most decided. From all parts of the bell-jar they crowded into the path of the beam, and were most numerous at that side of the jar which was nearest to the light. Indeed, close against the glass they formed an almost solid mass, which followed the light wherever it was moved. The individuals composing this mass dashed themselves against the glass nearest the light with a vigor and determination closely resembling the behavior of moths 1190 Recent Literature. [ December, under similar circumstances. There can thus be no doubt about Sarsia possessing a visual sense. Dr. Romanes then describes his experiments on the covered- eyed Medusz to ascertain the amount of section which their neuro-muscular tissues will endure without suffering loss of their physiological continuity. In Aurela aurita (Fig. 1) the nervous system is compared to a disk of muslin, the fibers and mesh of which are finer than those of the finest and closest cobweb, and if we imagine the mesh of these fibers to start from these mar- ginal ganglia, we shall gain “a tolerably correct idea of the low- est nervous system in the animal kingdom.” Now if seven of these eight ganglia are cut out, and the disk mutilated as in Fig. 2, yet the contraction waves, starting from the single ganglion Ni ANY vf ot ee So Joe a —= n y - Fic. 2.—Aurelia, with its disk cut radially. = left, “continued to zigzag round and round the entire series of _ sections,” n raction waves, emanating om /, passed’ in the direction rep- ted by the arrows without undergoing any appreciable loss completing the circular cut at z, the ring 1885.

By sever- ing the nerves at the base of each of the five rays, or by dividing the nerve-ring between all the rays, the animal loses all power of coordination among its rays (Figs. 14, 15).

On the other hand, if only one out of the five eye-spots were left intact, the animals crawled towards the light as before. It may be added that single detached rays of star-fish and fifth-part segments of Echini crawl towards the light in the same manner as entire animals, provided, cf course, that the eye-spot is not injured.” Finally, the presence of a sense of smell in star-fish which had been kept fasting for several days, was proved by presenting them with small pieces of shell fish. They immediately crawled to the food, and “if a small piece of the food were held in a pair of forceps and gently withdrawn as the star-fish approached it, the animal could be led about the floor of the tank in any direction.” By progressively cutting off the rays and other experiments, it was found that the olfactory sense was equally distributed throughout their length, but along the lower surface. These researches are certainly of much interest, and' are posi- tive additions to our knowledge of the nervous system and of the physiology of these types of life. Jorpan’s CATALOGUE OF FISHES OF NORTH America.'—This catalogue will be a sxe gua non of the ichthyologist. It is not only an index to the subject, but a good illustration of a generally rational nomenclature. The number of species now known is 1683. This number will be increased to a moderate extent from fresh and coast waters, and to a greater degree from deep-sea ex- plorations. Thus the take of the Fish Commission steamer A/- _batross, for the past season includes seventy-five species which are not yet described. Wa Professor Jordan’s efforts to do justice to honest work have been in the main successful. While employing such of the names of Rafinesque as are accompanied by recognizable indications ; others formerly adopted are rejected, as resting on no sufficient evidence. We think, however, that in a few instances the author > has gone a little further in favorable consideration of slip-shod work than justice to good work demands. Thus he adopts the two names Hypsoblennius and Reinhardtius, which were proposed without diagnosis or explanation, in preference to Isesthes and _Platysomatichthys, which were defined when proposed. Professor Jordan has not previously taken this position, and he now informs Ca the Fishes known to inhabit the waters of North America north of the Wie: atte : By D. S.

Commissioner of Fish and Fisheries for 1884). 1885, p. 185. 1200 Recent Literature. | December, us that it is opposed to his preferences and convictions, as it is to all the rules of nomenclature in existence. A characteristic which it would be well for American nat- uralists to imitate, is the classical form and derivation of most of Professor Jordan’s names. They display a refreshing contrast to the poverty of invention and barbarous constitution of the handi- work of too many of our countrymen of earlier years. Moreover we do not find the extravagant use of personal names, which has so prevailed of recent years in England and France. The dedi- cation of a species to men of desert, still remains a compliment in this country, whatever it may have become elsewhere. We append the following special notes apropos of one which appeared in the NATURALIST for 1885, page 814. In this note we did unintentional injustice to Mr. Meek in criticising determina- tions which we are informed, were mostly made by Professor Jordan. With regard to the Pantosteus platyrhynchus, whose characters were said to be due to “ shriveling” of the specimen, our objections were well taken; as Professor Jordan intorms us that this word is due to aslip of memory, and should be replaced by “soft and limp,” the words used in his private notes. Further, Professor Jordan states that he cannot find barbels in either Meda fulgida Gir. or M. argentissima Cope,as I have described them in the latter, and as Girard failed to observe in the former. The former is very abundant in the San Francisco river, one of the heads of the Gila in New Mexico, where it is the small minnow of the stream. Like Jordan, I find no barbel in any specimen. I have reason to suspect the correctness of the locality given me as that of the M. argentissima, i. ¢., the head waters of the Rio Grande. I suspect it comes from the waters of the Great Colorado. The locality given me for the Pantosteus guzmaniensis Caress “Arkansas river,” I have long suspected to be erroneous. have now reason to believe that it comes from the head waters of the San Juan river, a branch of the Colorado. _ Professor Jordan adopts very properly Gill’s new order of Lyomeri, for the remarkable Eurypharyngide. -5 DC, RECENT BOOKS AND PAMPHLETS. an, C.

Kustik, in a valley about fourteen miles long and three-fourths of a mile wide, is a Jamshidi town; but twenty miles to the east of it commences the Hazara country, a vast plain stretching to- ward the north, and eroded into a chaos of steep hillocks and hollows by the Murghab drainage. Kala-nau, the chief town of the Hazaras, is a prosperous one. The soil of the Hazara country is excellent—only the manual labor is needed. The Hazaras have enormous flocks of sheep and cattle. As far back as the earliest periods of Arabic history, Badghis has been connected with Herat. It comprises the land watered by the Murghab and its tributaries. Its principal valley is Penjdeh. The Afghan forts of Bala Murghab and Meruchak are the only modern buildings north of the debouch of the river from the gorge in the Tirband-i-Turkistan, for the Jamshidi and Saryk . Turkoman population live entirely in kibiskas or felt tents. About twenty-eight years ago the Saryks, driven from Merv by the Tekkes, received the sanction of the Jamshidi chief, and located themselves at Penjdeh. These Saryks were once, togeth- er with Tekke, Salar and other Turkomans, the scourge of north- era Persia, but since Russia has closed the slave marts, they seek for a stable government, and are giving their attention to agri- culture. The Saryks own nearly 200,000 sheep. North of the Badghis, a tract of country between the Mur- ghab and the Heri-rud is called Chol, which is simply Turkoman for a desert that is not a sand desert. The light soil bears short grass almost everywhere until the dry season, and where there is less grass there are usually more bushes, the latter marking a more sandy soil. : The salt lakes of Yar-oilan are situated in depressions, the west- ern one about 950 feet below the surrounding country, and 1430 feet above sea-level, while the eastern one is about 800. feet above sea-level. The beds of these lakes are a mass of hard salt, cover- ed with a very little water. The western lake is the source from which the Tekkes get their salt, while the Saryks tse the eastern lak e. In the discussion which followed the reading of Sir Peter Lumsden’s paper, Sir Hy. Rawlinson gave his reasons for the identification of Meruchak with the upper Merv or Merv-el-Rud, said to have been founded in the fifth century by Kesra Anushir- wan. The larger Merv, now in Russian possession, Balkh and Herat are the three oldest cities of Aryan civilization. The Paro- pamisus of the Greeks extended no further westward than Herat, the westward continuation being called Sariphe. ds / At Penjdeh, in a sandstone cliff 200 feet above the river, are some artificial caves, evidently once inhabited. The largest has a central passage 150 feet long, nine wide, and nine high to the top 1204 General Notes. [ December, of the vaulted ceiling. Doorways on each side lead to rooms fifteen to nineteen feet long, and of the same width and height as the passage. Doors were once placed in the entrances, as is proved by the holes for the fastenings. Narrow staircases lead to upper rooms, probably store rooms. Places for lamps remain, and there are traces of soot, but no carvings or inscriptions exist. Many other similar but smaller caves are found all along the valley. The Carolines—The Caroline islands were first discovered by a Portuguese navigator in 1526, and during the rest of the six- teenth century were frequently visited by Spanish and Portuguese explorers. They were first named the Carolines by a pilot named Lezcano, about 1686, in honor of Charles II of Spain. Towards the end of the seventeenth century the Spaniards in the Philip- pines and Mariannes learned something about the Carolines, and an imperfect map of the group was sent to Pope Clement XI in 1705. In 1710 the Jesuits of Manila sent missionaries there, but these, with a few soldiers who accompanied them, were massacred at the Pelews. Though navigators of all nations visited these islands, their number and exact position, as well as the hydrog- raphy of the seas in which they were situated, remained unknown until 1817, when they were visited by Kotzebue. After him came Freycinet in 1819, Duperrez in 1824, Dumont d’ Urville in 1826, and others, and from these came the first accurate accounts. The group, situated west of the Marshalls, and north of New Guinea, contains about 500 islands, most of which are atolls. The number . Of real islands is only forty-eight, but as each has a certain num- ber of islets around it, there may be said to be forty-eight groups; forty-three of these are low coral islands, while five are basalt with coral at the base. There are three main groups, separated by two large channels ; the principal island of the eastern group is Ponape or Ascension, that of the western Eap, Jap or Yap. Ponape is sixty miles round and has in its centre a peak 2860 feet high. Upon it are some curious ruins, apparently the remains of a large building made of blocks of basalt. There are two rainy seasons, January and August, and the climate is comparatively temperate. The population is from 18,000 to 20,000. The principal elements are Malay and Maori, but there is also a mixture of Negrito and Papuan, and in later times a Japanese and Chinese element was added. The language is also mixed. In some islands there are two languages—the vulgar and the polished. Zz abu is practised. wach group of islands has its chief, whose power in time of peace is nominal, but in time of war is unbounded. _ The Pelews, the most western isles of Micronesia, about 600 _ miles east of the Philippines, are a group of ten principal islands and a number of islets. The largest island, Babelthuap, is about uirty miles long. All the islands are covered with thick forests. population is about 3500, and is probably the result of a 1385. ] Geography and Travels 1205 mixture of Malays with an inferior race of aborigines. The kin has instituted an order, the insignia of which is the first cervical vertebra of a dugong. An interesting account of these islands will be found in the * Animal Life” of Semper, who spent some time upon them. M. E. Planchut, in a recent issue of the Revue Scientifique, states that the people of the Carolines are in continual relations with those of the Mariannes, which undoubtedly belong to Spain, that the Caroline natives are treated as compatriots when cast upon the Philippines, and that in the eyes of a Spaniard the par- tition made by Alexander IV is still in force. The entire area of the Carolines, Ualam, Panope, and Kong excepted, would not cover more than.200 miles in length by 200 meters in width. ` Thus the population is about 500 to the square mile. The same writer states that the people believe in a supreme being, whom they call Machi-machi. heir temples are pyramidal huts with a rough-hewn stone in front, and it is believed that were this stone to be raised by a chief who wished to chastize a mutin- ous people, the earth would tremble and the sea leave its bed to drown the rebels. M. Planchut states that the Palaos or Pelews have only 1200 inhabitants. Corea.—Beyond the granite mountains which surround Siril, Mr. Carles has come upon extensive lava sheets covering a large por- tion of Corea. “There are three great oval fields of lava passing almost in a straight line through the mountain chain which runs from the north to the south of Corea, at a height of about 1500 feet above the sea near the divide, and of 500 feet on the lower levels. There is also another plain about four miles wide and twelve miles long to the east of the Kaun-Song district, the direction of which is not so well defined, but in which the depth of lava is apparently greater than that in the others.” No crater is visible to account for the enormous mass of lava; which must have welled up from extensive fissures. Asiatic and Oceanic News—Mr. Gardner, British Consul of Newchwang, estimates the population of Manchuria at 15,000,000, Its three provinces are Heh-lung-Kiang, Kirin, and Féngtien, The port of Newchwang was opened to trade in 1861. The Sakeis of Selangore, in the Malay peninsula, seem to have no form of religious worship, but believe in omens. They kill small game with a blow-pipe and dart poisoned with Upas-juice, and large game with a kind of cross-bow formed of a bamboo spear placed in a grooved log, and a bent sapling held back by a rattan cord. This is stretched across a path inthe woods. The Sakeis live in bamboo huts thatched with palm-leaves. They area shy, harmless people, similar in appearance to the Malays, but smaller in statue and with wavy hair. The Geographical Society of Hamburg, in a recent publication, gives the area of Kaiser Wil- helm’s Land or German New Guinea at 34,508 square miles, 1206 General Notes. | December, The other German annexations in the Pacific are New Ireland, 3398.8 square miles, New Britain, 9348.8 square miles, and the Bismarck archipelago 15,261.6 square miles, in all about 65,512 English geographical square miles.

Iljin and Dimick have traveled among its glaciers, climbed its passes and given an account of their travels in Petermann’s Mittheilungen. Ushba is estimated at 16,500 feet, Tetuuld at15,500 or thereabouts. The Swanetians, to whose brutality Russian officers fell victims a few years ago, are now quiet. M. Dimick has explored the glaciers of Elbruz. From the resumé of these explorations given by D. W. Freshfield, it does not appear that they add greatly to the work done by Mr. Grove, Captain Telfer, Mr. Phillips-Wolley and Mr. Fresh- field. Arrica.—African News,—Notwithstanding the comparative fail- ure of M. Giraud’s expedition, he has added much to our knowl- edge of Lake Bangweolo and its neighborhood. The form of the lake, as given by him, differs widely from that given by Living- stone, and the Luapula head of the Congo issues from its south- ern prolongation. M. Giraud has traced it as far as Lake Mcero. or Mero Mkata. It may yet be proven that the Lualuba, may be the true head-stream of the Congo, as, where it issues from Lake Upembe, it has, according to Herr Reichard, a width of © 1000 to 1500 feet. Mr. Grenfell reports that Tippo Tib, the well-known Arab slaver, is evidently preparing for a permanent occupation of Stanley falls. He is making large plantations and is expecting 2000 more men. From the collections made by M. Humblot during a stay of several months on Great Comoro, it appears that no indigenous mammal is found there. Thirty- four species of birds were found. After an examination of the collections MM. Milne-Edwards and Oustalet came to the con- clusion that the fauna has no relation with that of Madagascar, but has been imported from neighboring regions, _ AMERiIcA—American News—Mr. Glaisher has ascended the Berbice river and Wieroonie creek from Georgetown.

Last year the topographical surveyor of Norrland found that Sarjekjakko, in Swedish Lapland, is quite 1000 feet higher than Sulitjelma, that is, about 7000 feet. Dr. Svenonius now states that Kebne- kaisse, also in Lapland, has been ascertained to be 7300 feet above sea-level —--The rocky islet. Munken, three and a half miles south of Surhbd, has completely subsided. The rock is well-known in history. It is mentioned in 1673 by Pastor Lucas Jacobson Debes, and plays a conspicuous part in geographical literature, especially with reference to the Zeni narrative. The islet was formerly seventy feet high, but is now no higher than the surrounding rocks, so that the sea covers it even in fine The shoals around are dangerous, and will now be more so. In 1800 the rock was described as like a ship under full sail when seen from seaward, while from the/land it resembled the figure of a monk. GEOLOGY AND PALAZONTOLOGY. PoLeMics IN PaLt#onTotocy.—The present activity in verte- brate paleontology is accompanied by considerable controversy in various directions.. M. Lemoine and M. L. Dollo are at issue regarding the identity or non-identity of the genus Champso- saurus Cope and Simcedosaurus Gervais; M. Dollo maintaining their identity and referring to the Champsosaurus, a skeleton found at Erquelines. M. Lemoine states that the Erquelines example comes from an horizon different from that which yielded Simcedo- saurus, and that, in order to force an identification, M. Dollo has accused him (M. Lemoine) of errors which he did not commit. On the identity of the American and Cernaysien forms M. Le- moine reserves his opinion. M. Dollo answers by asserting the identity of horizon of the French and Belgian specimens, and giving reasons for considering the remains as belonging to the same species. Passing in review the cranium, atlas and axis, ver- tebrz, scapula and coracoid, and other parts, he not only denies the existence- of any proved divergence between the American, Cernaysien and Belgian examples, but declares that the bones described by M. Lemoine as scapula and coracoid are really not those bones, since they are shown as placed one over the other, whereas there is a true articulation between the actual scapula and the coracoid. He suggests that the scapula of M. Lemoine may be a part of the coracoid. VOL. XIX.—NO, XII, 79 s 1208 General Notes. [ December, Dr. Schlosser, of Munich, endeavors to show that Dr. Lydek- ker is in error in proposing, in the catalogue of the vertebrate fossils in the British Museum, to combine certain species of, Ro- dentia, described by him in his monograph of the Tertiary Roden- tia of Europe. . Dr. Lydekker, in the London Geological Magazine, reviews the illustrated papers published by Professor Cope in the AMERI- can NATURALIST on American fossil Vertebrata. He differs gen- tity of Hyopsodus Leidy with Microchcerus Wood; and of Esthonyx Cope with Miolophus Owen. Professor Cope, in a note to the Geological Magazine, shows that there is not sufficient ground for the latter identification. Dr. Baur believes that the bone in Iguanodon supposed by Marsh to be clavicle, is really sternum, as indicated by Dollo. THE ANKLE AND SKIN OF THE DINOSAUR, DICLONIUS MIRABILIS. —The fibula of this saurian lies at its distal end in a groove of the external part of the front of the tibia. It is compréssed so as to be anteroposterior. It terminates in an epiphysis-like cal- caneum. The astragalus has the usual form, and embraces the tibia closely. Its anterior ascending process is rather short and thin. Posteriorly the tibia rests on the astragalus and is not overlapped by it. A portion of the extremity descends and fills an angular space which enters between the astragalus and cal- caneum behind, and takes part in the ankle-joint.

The .measurements exceed those of the typical £. crenidens (which has not, so far, been found out of the Valley of Mexico), and there are some other differences in the distribu- tion of the enamel-folds. It is distinguished from the other species of Equus by the small diameters and concaved inner border of the anterior internal column, by the simplicity of the enamel-folds, and the crenate character of the margins of the lakes, together with the large dimensions. The crenation is less obvious in some specimens than in others, and in the one here noticed is almost confined to the borders of the posterior lake.

H. der. The group Archipolypoda resemble the Diplopoda in of legs on every segment; while in the Proto- X 1885. | Geology and Paleontology. I21I sygnatha only a single pair of legs is borne by each segment, and the group thus resembles the Chilopoda. For a brief period after leaving the egg, modern diplopods and pauropods have a shorter body than in after life, and the first three segments bear but a single pair of legs. In adult life these first three segments still bear but a single pair of limbs, while all the other segments, both those which exist in the larval state and those which develop afterwards, bear two pairs. The Chilopoda have these same three anterior pairs of limbs eariy and permanently developed as organs of manducation, while all other segments have but a sin- gle pair. Paleontological evidence is in favor of the view that the dorsal scutes of Diplopoda are compound. The archipolypo- dous type is the oldest, and there is evidence that some of the Carboniferous forms were amphibious. The group culminated in the Carboniferous, and does not appear, to occur later than the Dyas, while, with one doubtful exception, no true diplopod is known to be older than the Oligocene. According to S. H. Scudder be- tween twenty and thirty species of pre-Tertiary Arachnida are now known, and the earlier forms, chiefly of Carboniferous age, belong either to the scorpionides or to the Anthracomarti, a group which is not known later than Paleozoic times, the only Mesozoic arachnids yet known being true spiders. In the amber deposits of Prussia all the suborders of Arachnida occur except the Pedipalpi and the already extinct Anthracomarti. rG B. Villa (Atti. d. Soc. di Sci.

Geological Survey consists of notes on the stratigraphy of California, by G. F. Becker. The metamorphic rocks of the coast ranges often show ' proof that plication was not effected by flexure but by innumer- afterwards re-cemented by silica. The Knoxville beds, the age of which is near the limits of the Jurassic and Cretaceous, are the youngest beds of the coast ranges which are known to have experienced the peculiar magnesian and siliceous metamorphism of these ranges. The overlying Chico beds are shown to be non- conformable with the Knoxville beds, and over wide areas the Chico, Tejon and Miocene strata seem to be perfectly conforma- ble with each other. The upheaval and metamorphosis of the Knoxville strata is referred to the close of the period of their deposition. The auriferous beds of Mariposa are referred to the same horizon as the Knoxville beds. It is maintained that there has been a great east and west compression of the country, con- nected with the great faults in the Wasatch and the Sierra, while a land barrier existed in the position of the Sierras from a time prior to the Cretaceous onward, and accounts for the difference 1212 General Notes. | December, in the faunas of the Pacific Coast waters and those eastward of them.

Achiardi gives the particulars of an examination into the macroscopical and microscopical characters of the trachyte and quartziferous porphyry of Donoratice, near Pisa, Italy. The trachyte is covered, here and there only, with Eocene sediments which seem to have been disturbed by the eruption. The porphyry traverses the parti-colored schists of the Upper Lias and also the marbles of the Lower Lias, and is only about 400 meters distant from the trachyte, the space be- tween being occupied by Eocene sediments. D’Achiardi finds the materials of these two rocks to be chemically the same, and the mineral species contained in them, for the most part, identi- cal, but while the trachyte has cooled rapidly upon the surface of the rocks, the porphyry was intruded through them, and cooled slowly. The same mineralogist notes the presence in the Apuan Alps of tormalinolite. more pronounced, consisting of loops, convex usually toward the west and south, but in rare cases toward the north-west. Traces of four great lobes of the ice-sheet, pushing through from the James to the Missouri, can be found. MINERALOGY AND PETROGRAPHY.' METEORITES.—A number of very important contributions to the literature of these interesting bodies, which reach our globe directly from the regions of space, have recently been published. _ Papers relating to meteorites have heretofore been largely con- _ fined to detailed descriptions of particular falls. With the ex- eption of Rose’s essay on the classification of these bodies, little of a general nature regarding them has been produced until ithin the past year or two. Now, however, we have at least four by Dr. Geo. H. WittaMs, of the Johns Hopkins Univ., Baltimore, Md. (OD RR Re Pee ae Teoma ea ere ee Td 1885.] Mineralogy and Petrography. 1213 extensive works dealing with their classification and the results of their microscopical and chemical study. These are, moreover, quite se in their aim and scope. First may be mentioned Dr. M. E. Wadsworth’s Lithological Studies! the frst part of which, published in October, 1884, con- tains much useful information regarding meteorites. The results of the microscopical study of thin sections of these bodies by many investigators, as well as by Dr. Wadsworth himself, are properly classified with terrestrial rocks as a part of the same series, in which they also represent certain members more basic than any found in the earth’s crust near its surface. Probably the work which will do most to spread abroad just and accurate ideas of the exact nature and mineralogical com- position of the meteorites, is the series of microphotographs re- cently published by Professor G. Tschermak, of Vienna.? There is scarcely any one to whom a richer collection of this rare material was accessible, nor any one better fitted by his own researches for successfully preparing such a volume. Thin sections, one hundred in number, illustrating every phase of structure and composition met with among meteoric stones, have been reproduced so ad- mirably by photography as to afford the best possible substitute for the originals. When it is remembered how few can ever hope to thoroughly study sections of meteorites themselves under the_ microscope, the value of these photographs, which necessarily far exceed any possible descriptions, will be appreciated. Each plate is accompanied by a full explanatory text. The work was executed by J. Grimm, of Offenburg, who is already well known for his superb microphotographs of rock sections, edited by Pro- fessor E. Cohen. The same firm promises a similar set to illus- trate the structure of meteoric irons, the appearance of which will be awaited with interest. Professor Staislas Meunier, of Paris, has recently published an elaborate work entitled “ Les Météorites.”3 In this he presents a new classification, as well as his views respecting the origin of these bodies. The latter agree with those of Reichenbach, Haidinger and Tschermak in considering meteorites, at least such as possess a breccia-like appearance, as aggregations of much smaller bodies of matter distributed through space, which have been brought together by their mutual attraction. Another extremely important paper on meteorites is that b Dr. Aristides Brezina, curator of the royal mineralogical cabinet 1 Memoirs a Comp, Zool. at Harvard Col.

This is ostensibly a report on the condition of the meteoric collection belonging to the cabinet, but really contains much matter of very general interest. Brezina can find nothing in the structure of the meteorites to indicate a secondary or con- glomerate nature. He regards them as the product of a very rapid crystallization from a homogeneous magma. Respecting their origin, he considers the old theory of Chladni (1818) and von Hoff (1835) as the most probable. According to this the meteorites reach the external atmosphere of the earth as dust- like or gaseous agglomerations, which, by the sudden diminution of their cosmic velocity, are enormously heated and at the same time condensed into solid bodies. The classification adopted is in the main a petrographical one, following in the principal groups those of Rose and Tschermak. Many new subdivisions are, however, introduced to cover the results of the more thorough and elaborate study. The meteoritic collection in Vienna is the largest in the world, representing 358 localities, while that of London has 350 and that of Paris 300. Short notices have recently appeared by Professor C. U. ‘Shepard, on the Fomatlan, Jalisco, Mexico meteorite (which fell August, 1879), which is composed largely of olivine and octahedral crystals of nickeliferous iron;? also by the same writer on the meteoric iron of Trinity county, California Meteoric irons have also been described and analyzed by N. T. Lupton from Santa Rosa, Mexico ;* by George F. Kunz, from Glorietta Mt., Santa Fé county,’ New Mexico; and by R. B.

Rinne concludes that crystals of milarite, which are apparently hexagonal, were really so at the time of their formation, and that their molecular disturbance is due to a subsequent change of conditions, as is true in the case of leucite and boracite.? PETROGRAPHICAL News.—The second part of the second vol- ume of Professor J. Roth’s Allgemeine Chemische Geologie has just appeared. This treats of the younger eruptive rocks, and especially on account of the wonderful completeness of its literature references, will form, as do the other parts of the same work, a most valuable addition to the library of every working geologist and mineralogist. A very concise elementary text- book of microscopical petrography has recently appeared, by Professor A. von Lasaulx, of Bonn. In spite of its small size it brings the essential points of this rapidly developing science down to date, and is especially to be recommended for its full bibli- ography.—In his recent exhaustive optical study of the mineral leucite, Professor C. Klein, of Göttingen, describes in some detail a new and very complete mineralogical and petrographical micro- scope, which is constructed by the well-known firm of Voigt & Hochgesang, of Gottingen.‘ This instrument, of which a cut is ee given in their latest catalogue (1885), may be had for 800 marks - ($200), andis undoubtedly the most satisfactory microscope in the market for the especial uses for which it is intended. Becke, of the University of Czernowitz, contributes a paper o the twinning of rock-forming pyroxene and amphibole.’ He finds in certain Hungarian pyroxene andesites that the bronzite crystals are frequently grouped i in radiating groups, in accordance with three anng laws, viz: twinning planes I, Pa (vom Rath); 2, 2P%, and 3, iF o The first of these is the most common and corresponds. very closely to the twinning law for augite, twinning plane P2. The frequently mentioned twins of augite and hornblende in rocks, with a composition—face apparent- ly inclined to the vertical axis, the writer follows Mr. George F. Becker® in considering merely ordinary twins, parallel to œ P 3, which are cut in the section parallel to some pyramidal face. J. H. Kloss, of Karlsruhe, has made some interesting contribu- tions to the subject of secondary hornblende in rocks.” He finds abundant evidence of compact as well as fibrous hornblende (uralite) originating from the paramorphosis of pyroxene, and can 1 Das mineralogische Museum sap?

[ December, see no reason why a single, homogeneous individual of the former mineral should not replace one of the latter. He furthermore thinks that such secondary hornblende (which cannot be regarded as an alteration product in the common sense), should be used for purposes of rock classification, and suggests names as uralitite, uralite-diabase, uralite-gabbro, etc., to be employed, of course, only where the secondary nature of the hornblende was beyond doubt. culated to throw light upon the original form of the minerals of the more basic massive rocks. Many of these, like labra- dorite, olivine, hypersthene and diallage, are well known to often possess a peculiar luster on cleavage surfaces due to the _ presence of inclusions, These are generally regarded as original in their nature, but Professor Judd considers them as secondary. He thinks that at great depths, under the action of pressure, cir- culating waters would have such an increased solvent effect that in certain planes a portion of the crystalline substance would be dissolved, leaving cavities of regular shape, resembling in their nature the “etched figures” which are produced in crystalline _ planes by the action of certain reagents. Into these cavities, or negative crystals, foreign matter is infiltrated, thus producing the so-called inclusions of indeterminable microlites. This process is designated as “ schillerization”’Messrs.

THE Grasses OF Matne.—Under this title Professor Fernald, of the Maine State College, has brought out a neat pamphlet of * seventy pages and forty plates. It is designed for the use of 4 the author’s students, as well as for the farmers of the State. In the introduction is given a general description of the structure of grasses, with a pretty complete list of the technica) terms used in ordinary descriptive works, and acouple of pages on the composition of grasses. An analytical key precedes the descriptive portion of the book, the latter occupying about fifty pages. Common names and the pronunciation of the scientific names are given in every case. The descriptions are much simplified, and appear to be fairly accurate. Short notes upon their agricultural value follow each species. Eighty-one species belonging to thirty- eight genera are described, and of these forty-two species are figured in the plates borrowed from the department of agriculture at Washington. SPECTRUM OF CHLOROPHYLL.—When a ray of white light which has passed through a coloring-matter, for instance, a solution of one of the coal-tar dyes, red wine, or a solution of chlorophyll, is examined by means of a spectroscope, certain dark bands, known as absorption-bands, are observed at definite places in its spectrum. For convenience in examining the spectra of small amounts of coloring matters, a direct vision spectroscope attached to the tube of a microscope is employed, and the color- ing-matter in question is placed in a flat-walled bottle or a glass cell on the stage of the microscope. The ray of light which is reflected from the mirror under the stage passes first through the colored matter, next through the objective, and lastly through the prisms which compose the microspectroscopic attachment to the tube. In order to compare the spectra of different substances, a sec- ond prism or set of prisms is often used, by which the spectrum of a second liquid can be projected by the side of that of the first. The spectra of chlorophyll solutions from two different sources - can thus be at once compared. One of the combinations can also be employed to project the solar spectrum (unchanged by passing through any color whatever), and its constant lines (Fraunhofer’s lines) can be used for the determination of position of the bands seen in the spectrum of the liquid by its side. The spectra of many substances, among which chlorophyll oc- cupies a prominent place, have absorption-bands of such con- stancy in position and appearance that they are justly regarded -as characteristic. The spectrum of an alcoholic solution of chlorophyll has been shown to be essentially the same as that of the chlorophyll granule itself. In order, however, to obtain all 1 Edited by PROFESSOR CHARLES E. BESSEY, Lincoln, Nebraska. * 1218 General Notes.

L. Goodale, in Bot. Text-Book. THE TREATMENT OF SETS OF BoTANICAL SpEeciMENS —In this day, when so many sets of plants are distributed by the many collectors and elaborators of groups, it becomes a serious ques- tion what to do with them in the herbarium. A single set, or even a few sets may be kept in the original form and consulted in this way, but when one has to ransack a dozen or more fas- cicles, in as many different sets, in order to make a comparison of the species of a particular genus, the trouble is entirely too much for a busy man. One dislikes to tear up his sets of Ellis’ North American Fungi, Thuemen’s Mycotheca Universalis, Linhart’s Ungarns Pilze, Wittrock and Nordstedt’s Algæ aque dulcis ex- siccate, Rabenhorst’s Algz Sachsens and Algz Europas, etc., etc., but really the labor of running over the numerous fascicles makes any other course impracticable. In the herbarium of the University of Nebraska, all sets of plants, of whatever groups, are cut up and distributed. The labels in all cases are distinctive, indicating with certainty the set to which each specimen belongs, and its serial number. Any specimen can thus be as readily re- ferred to as if it were retained in the original fascicle, while the ease of consultation and comparison is greatly enhanced. Botanica Nores.—-The botanical portion of the second an- nual report of the Wisconsin Agricultural Experiment Station, by Professor Trelease, is mainly devoted to the spot-disease of strawberry leaves (Ramularia tulasnet), Three figures serve to make the descriptions much more easily understood, although the text is admirably clear.’ A paper of this kind is worth more scores of pages of so-called “experiments,” which too often constitute the bulk of the reports from American experiment stations. : er’s synopsis of the genus Selaginella, which has been running through the Journal of Botany for many months, is brought to a close in the October number. The whole num- ber of species described is 312, of which 105 are here described for the first time. B. M. Everhart, of West Chester, Pa., has compiled an alphabetical index to the species of the first fifteen centuries of Ellis’ North American Fungi. It will prove of great service to all who have occasion to refer to Ellis’ spetimens. From it we find that there are in the fifteen centuries thus far _ published twenty-five species of Peronospora, eighty of Puccinia, twenty-eight of Uromyces, fourteen of Ustilago, forty-seven of Polyporus, eighty of Peziza, etc., etc. Professor Beal has pub- - he: d in Bulletin No. 5, of the Michigan Agricultural College, the results of experiments made upon the vitality of seeds, from eal s that of seeds enclosed in sand in bottles and — 1885. | Botany.

No new species are described. Professor Penhallow published, in the Canadian Record of Science for October, a paper upon the distri- bution of the reserve-material of plants in relation to disease, from which it appears that an abnormal storage of starch in the pith, wood and bark of the peach is associated with a deficiency of potash and chlorine and an excess of lime. This abnormal stor- age is accompanied apparently by imperfect nutrition, due to the loss of power of the tissues to dissolve the starch, which accord- ingly accumulates——The July Torrey Bulletin contains a paper by Professor Trelease showing that the fungus parasitic on Jun- cus tenuis, and hitherto known as Ustilago junct Schweinitz, is properly not an Ustilago at all, but a species of Cintractia. Ac- cordingly it must hereafter be known under the name of Cn- wactia junci (Schwein.) Trelease. The only other known species of the genus is C. aaicola (B) Cornu, from the southern United States and the West Indies. From a study of the develop- ment of the leaves of Pinus monophylla and P. edulis upon young trees growing upon his grounds in Germantown, Pa., Thomas Meehan concludes that the former is a depauperate state of the latter. His paper appears in the August Torrey Bulletin. The «Association Number” of the Botanical Gazette (Sept. and Oct.) contains forty-six pages of interesting matter, We are much pleased to read the announcement that beginning with the new year the size of this indispensable journal will be increased to at least twenty-four pages per month. An exhaustive index to vol- umes I to x will be published at the close of the present year. Professor John M. Coulter's Rocky Mountain Flora is in press, and will soon appear. It is to be uniform with Gray’s and Chapman’s Manuals, and will include descriptions of the plants from about the 100th meridian westward, and extending from British America southward through Colorado. ? 1220 General Notes. [ December, ENTOMOLOGY. OCCURRENCE OF COLIAS NASTES IN THE PAMIR MOUNTAINS.—In the Investia of the Russian Geographical Society is a paper by M. Grum-Grzimailo, who has journeyed, says Nadure, in the mountains north of the Alay region of the Pamir, in Central Asia.’ Ona rich Alpine pasturage, where Kirghizes are in the habit of staying, he found Colas eogene, Arctia erschoffi, etc., which are common almost exclusively to the Himalayas and the Southwest Thian-Shan. On the plateau between the Kara-Su and the Aram, with other rare Lepidoptera were species of Colias and Parnassius. On the Dje Kaindy pass, the Lycaenz were numer- ous, so that in the space of three meters the author found fifteen species of them, of which three were unknown to him. Another find of great interest was that of C. mastes: The late Mr. Fed- chenko had alrec dy caught one female butterfly, which was de- termined by M. Erschoff as Colias nastes. This species having been found formerly only in Labrador and Northern Lapland, the determination remained doubtful, the individual having been but a female. M. Grzimailo has caught a number of both males and females, which really proved both to belong to C. xastes. The writer says it remains now to explain the strange extension of this species. He does not seem to be aware that several (nine species) other Labrador Lepidoptera occur in the Altai mountains of Northeastern Asia. Tue Eye anp Optic Tract or Insects.—In his essay on this subject Dr. S. J. Hickson (Quart. Journ. Micr. Science, April) describes in detail the eye and optic tract of the flesh fly (Musca vomitoria). The pseudo-cones he has found to be composed of four cells, with their nuclei situated internally, each one contain- ing a large watery or albuminous vacuole, which serves the same purpose, and is morphologically homologous with the crystalline cone of the “eucone” eyes. There are six retinule cells, each possessing a nucleus situated in that part of it which lies imme- diately behind the pseudo-cones, and in some cases an additional nucleus, situated about half-way down. He has figured for the first time the interommatidial tracheal vesicles which have been previously observed by several investigators. In the optic tract he has described three ganglia—the opticon, epi-opticon and peri- opticon. The last of these is composed of a number of small cylindrical elements of a tissue composed of a sponge-work of _nerve-fibrilla, which he has called a “neurospongium.” The _ Opticon and epi-opticon are present in all insects, and in most of ae the higher Crustacea. The peri-opticon appears comparatively ate in development, but is never found even in the adults of eri-opticon, when present, is usually composed of a num- | | elements, which- partially fuse in Æschna and 1885.] Entomology. 1221 completely in Eristalis, Bombyx and the Crustacea. In Eristalis the peri-opticon is traversed by a number of delicate tracheal vessels. The terminal optic anastomosis of Nepa is more complicated than it is in Periplaneta, and seems to be an intermediate stage between the simple anastomosis, the true peri-opticon of Musca. A similar series of intermediate stages between the simple anastomosis and a true peri-opticon has been traced in the devel- opment of these parts in the bee. The development and comparative anatomy of the peri-opticon of insects is interesting, as it may indicate the mode in which central ganglia were first formed from primitive nerve-fibrils and cells. : His investigations seem to him to corroborate the opinion of the majority of previous investigators, that the retinule are the true nerve-end cells. How INSECTS ADHERE TO FLAT VERTICAL SuRFACES.—Herr H. Dewitz gives an account of some further observations on this subject, tending to prove that the secretion by which, e. g., flies adhere to window panes, is not a thin fluid of a fatty nature, but much more consistent. He adduces experiments to controvert Rombout’s view that a fly can maintain itself on a glass surface by one leg only, if that surface be vertical and if the body of the fly be in contact with the glass—/ournal Royal Microscopical So- ciety, October, 1885. is stated by Dr. F. Dahl to occur in spiders. In an earlier com- munication this author had pointed out the fact that Micrommeta virescens and M. ornata were simply two broods of the same species. He now advances another instance in Meta segmentata and M. menger, stating his reasons for believing them to be respec- tively spring and summer broods of the same species.—/ournal Royal Microscopical Society, October, 1885. Entomotocicat News.—In the twenty-eighth volume of the Annales de la Société Entomologique de Belgique, we notice de- scriptions of the metamorphosis of Leptinotarsa d lineata Stál and Tropisternus lateralis Fabr., by Dr. Eug. Dugès of Mexico. In the first part of Vol. xxıx of the same Annales C. Van den Branden publishes a catalogue of the aquatic carnivorous beetles. The family Dytiscidæ numbered, according to the Munich catalogue, 893 species; to-day the present catalogue enumerates over 1500 species. C. Kerremans also enumerates the Buprestidæ described since the publication of Gemminger and Harold’s catalogue. In the Comptes-rendus of the same Society Mr. S. H. Scudder shows that the Brachypyge carbonis, described by Dr. H. Woodward as 1222 Generar Notes. | December, the abdomen of a crab, is in reality the abdomen of an arachnid, of which six species are now known, one from the coal measures of Arkansas. In A. Walter’s article on the morphology of Lepidoptera in the Jenaische Zeitschrit for May, we have an ac- count of the mouth-parts of Acentropus. The transformations of Paraponyx oryzals, an insect pest of the rice- plant in Burma, are described and well figured by J. Wood-Mason, in a pamphlet printed in Calcutta. Its larva is aquatic and breathes by tracheal gills. We wish the author had given more detailed sketches of the gills and their relation to the body. We omitted to note Kowalevsky’s contribution to the post-embryonal development of the Muscide in the Zoologischer Anzeiger for Feb. 23, 1885. ZOOLOGY. THE SIGNIFICANCE OF THE CELL NUCLEUS TO THE PROBLEM OF HeErepi1y.—The results of the later researches upon fertilization and cell division, have tended to make biologists view the cell nucleus as of pre-eminent inportance for the life of the cell. In 1884, Kolliker, in his Entwickelungsgeschichte, stated, that since fertilization consists essentially in the fusion of a male with a female pronucleus into one segmentation nucleus which entails its hermaphrodite character upon its offspring of cell generations during ontogenetic development, this fact gives us the true reason why, and how every organism resembles its parents. The last two years have been fruitful in discussions of the problem of heredity in the light of nuclear investigations and have stimulated Kolliker to expand the above statement with more completeness and detail in the paper? of which this article is an abstract. From our present knowledge of the biology of the cell nucleus we may draw certain conclusions of great value as a basis for the discussion of the problem of heredity, as follows : The nucleus, and it alone, contains a substance which possesses the power of building up an organism according to specific characters, making it resemble the parents from whieh the nucleus origi- nally came—in other words, possesses the hereditary power. This follows from: (a) The nature of the spermatozoin: We know that but one spermatozoon is needed in the fertiliza- tion of one egg; we know that this must carry the hereditary traits of the father which he received from his ancestors both male and female; each spermatozoon is a nucleus. Kölliker, in 1844, held the spermatozo6n to be the equivalent of a cell, but later came to the conclusion that it represents a nu- cleus., Other Other biologists agreed with Kölliker so far as the dody of the Fptrmatosoòn is concerned ; but the fagellum, they said ts the cell protoplasm ; and hence a spermatozoon may ig der Zellenkerne fiir die Vorgänge der EAR r? Zeitschrift Zoologie. eee RAH, erstes erstes hqft. July, 183. ake bs er ae a oe TE es OEN ee 1885.] Zoölogy. TA still be the equivalent of a cell. This may be true, for instance, says Kölliker, for trematodes ; but he has shown that for the higher vertebrates the spermatozoa are, in toto, nuclei. It therefore follows that in the spermatozoa of lower animals the nucleus i is the necessary fertilizing part, the flagellum serving merely as a locomotor organ, being later absorbed by the yolk. The pollen grains of phanerogams are also nuclei. (6) The phenomena of fertilization : Since Bütschli, in 1872 discovered the two pronuclei in the newly fertilized egg, the phenomena of nuclear conjugation have been carefully studied, especially by O. Hertwig, Fol, and Van Beneden. It is agreed that the male element penetrates the yolk and unites with a portion of the egg-nucleus; but in some im- portant details there is disagreement. The most complete obser- vations have been made on Ascaris megalocephala by Van Beneden and by Nussbaum. These observers agree that only the nucleus of the zoosperm forms the male pronucleus ; though Van Beneden, even here, finds a “ perinuclear zone” which takes no part in the fertilization. It is also agreed that before being fertilized, or con- jugating with the male pronucleus, the egg-nucleus throws offa portion of itself in the polar globules, by a complex | process re- sembling indirect cell division. In this process it is generally agreed that the nuclear figure is divided equatorially; but Van Beneden strongly insists that the division is meridional. He further thinks the germinal vesicle is not an ordinary cell nucleus because a% the chromatin is in the nucleolus Minot, Balfour and Van Beneden think all cells are herma- phrodite; and that before conjugation can take place the male. cell must lose its female nuclein, and the female cell its male nu- clein which is passed over into the polar globules. But against such an hypothesis there are grave objections. (1) It is known that in the processes of spermatogenesis in many animals, no part of the spermatogonia is lost. (2) Usually two polar globules are successively formed by the repeated halving of the egg nucleus. Now to get rid of the male nuclein this sub- stance must be so distributed as to be separated by the plane of division from the remaining or female nuclein; and then, the male nuclein would be lost in the first globule and there would be no need of a second. (3) We know that the spermatozodn confers hereditary traits from both father and mother upon off- spring ; and likewise for the female pronucleus. Therefore we con- clude, the pronuclei are essentially tn their nature hermaphrodite. Kolliker plausibly suggests that the function of the polar glob- ules is simply to reduce the size of the egg-nucleus comparable to that of the male pronucleus. 1 This word, h: rodite, means pami that hereditary powers from two pies of ancestry, indefinitely dichotomously: co unded, are combined, and not what w popularly understand by the term.— oats : VOL. XIX,—NO, XII. 80 1224 General Notes. [ December, The general law of fertilization, stated by Strasburger for plants, and which we see from the above holds also for animals, is: Fertilization consists essentially in the conjugation of male with female nuclei ; these are ordinary cell nuclei; and the cytoplasm takes no part in the process. It is therefore erroneous to speak in a general way of the cell protoplasm as carrying the hereditary powers. Of the many writers who have treated this subject, only three or four have given more definite statements. Nageli calls that substance zdo- plasm, which controls or determines the specific characters of the cell, but does not limit it to the nucleus as does Kolliker and Born. Strasburger distinguishes between two sorts of idioplasm, that of the cell (cyto-idioplasm), and that of the nucleus (karyo- idioplasm). In the nucleus exists a substance of definite morphological and chemical character, known as nuclein or chromatin. With this sub- stance the idioplasm must be conceived as connected. (1) The chro- matin of the male pronucleus unites with that of the female pro- nucleus to form the chromatic figure’ of the segmentation nucleus. According to Van Beneden there is no union, but the chromatin loops of the pronuclei remain separate so as to give the segmen- tation nucleus a double character, morphologically, one-half being distinctly male and the opposite, female ; and this holds true of all its offspring. But Nussbaum found that before segmenting, the nucleus has a stage in which the chromatin forms a single fila- ment. Furthermore Van Beneden’s own figures do not seem to Kolliker, to support his view. (2) The processes of karyokinesis show how important it is that the chromatin should be divided between the daughter nuclei in a definite way. It is natural to suppose that to distribute the hermaphrodite idioplasm to the daughter cells, so that each shall get its proper amount, must be a delicate process. We have now to inquire how the idioplasm effects the work of heredi In the development of an egg into an adult there are two mo- ments at work, First, the cells multiply until a Saran pres number of cells needed by the organ is produced; second, these cells are separated into groups and are differentiated into the various | tissues. We may refer to the cambium zone of plants for a ' familiar illustration. 2 The structural characters of any organism depend o _ factors: (1) cell division, and (2) cell growth; both as a a quantity, a lity. Cell: multiplication, if great, will produce a large organ; if less, Tas The multiplication may be uniform or may be more certain | A ts. Thus in the arm rudiment, five points of id cel Cater opr with points of rest, and the five fingers cell division ~~, take place in one, 1885.] Zoology. 1225 two, or three planes, and give rise accordingly to very different aggregates, As to cell growth, the size will depend directly on it; but like multiplication, growth may affect some cells and not others; again, like multiplication, cell growth may take place in one, two, or three dimensions. W now readily see that the guantity and quality of cell multiplication and cell growth, according to a specific type of com- bination for the different organs and thus for the whole organism, builds up the individual with its specific characters, ow, the nucleus governs cell multiplication. (1) Division of the nucleus leads in cell division. (The author here shows that certain apparent exceptions are not really so.) (2) The position of the nuclear spindle determines the plane of division. The nucleus also governs cell growth. ` (1) Young and active cells have conspicuous nuclei, while cells that have done their work are without them. (2) The size of the nucleus increases as the cell increases (cf. Actinospherium). The nucleus in large cells may separate into many parts so that every portion of protoplasm shall have a nucleus to preside in it. In protozoa these nuclei fuse again before division of the cell, while cases where the mass breaks up without this union are where the nuclei have become independent cells, viz: swarm spores. (3) Artificial division of Protozoa, shows that pieces without a nucleus do not grow. (4) Free cell formation may be considered as due to the fusion of minute nuclei (vid. Berthold, Mitth. der Zool. Stat. Neapel, ii, p. 78) and around the nucleus thus arising a cell is formed. (5) As several of Haeckel’s innu- cleate monera have shown nuclei, when treated with appropriate reagents, Kolliker expects that all will do so when investigated by the methods of an advanced staining technique. (6) The activity of the nucleus is shown by the rays that stream from it in the protoplasm, and by the active manner in which it reacts towards stains. From this we conclude, that the nucleus has great and con- trolling significance for the cell, being in active relation to the protoplasm.! Some authors have given it the function of manu- facturing albumen, chlorophyll, etc. The structure of the cell, in fact its life history, ts conceived to depen on the nucleus, whose idioplasm has a minute structure of a definite type for each species ; and on this structure will depend the method of its work and how it shall react towards external influences. Modifying forces trix of achromatin; and that modern cytologists have generally applied the pert ereid, to only the chromatic portion, wholly ignoring the achromatic.— Y. W. 1226 General Notes. [December, to influence heredity must affect this structure and thus only, can produce variation. We have finally to inquire, what are the changes which the idioplasm suffers during the ontogenetic development of an or- ganism ? Lach cell which results from the segmentation of the first embryo nucleus must be the equivalent, in all respects, of this nucleus, and, theoretically, capable of reproducing the individual. Weis- mann has a theory opposed to this view. According to this author, only the very earliest cells produced in segmentation are set apart as germinal cells; all others have lost the power to be germinal cells, but must invariably differentiate into the organs of the body. Thus we really have no death, but only a series of germinal cells which gives off, by cell multiplication, from the fertilized egg, a mass of cells which differentiates into the indi- vidual. This aggregate alone is dissolved in the process known as death. Kölliker cannot accept this theory. Every organ begins in a mass of embryonic cells, from which parts may be renewed if lost. Cells that have differentiated may, under proper circumstances, regain their germinal power. The buds that appear at various points of a mass of embryonic vegetable tissue, essentially repro- duce the structure of the individual. In plants, the germinal cells can not be said to be set apart early in life. (Compare also adventitious buds.) Even in the adult animal organism, occur embryonic cells, such as osteoblasts and odontoblasts, the deep cells of the epidermis, cells of many glands, lymph, cells, and germinal cells. The last are themselves, like other cells, differ- entiated in a particular direction, some forming eggs and some spermatozoa. All asexual reproduction, such as fission, budding, parthenogenesis, shows that other cells besides germinal cells, can reproduce the organism. It would be an interesting inquiry to ascertain what circumstances cause the cells to reproduce the whole body or only a part. It is not necessary to hold the early differentiation of germinal cells, nor to locate them for all animals in the same embryonic layer, since all cells are primarily germi- nal cells like the fertilized egg; and according to the function they are to serve in the adult, they differentiate into the appro- priate tissues.— F. Nelson. Tue RETROGRADE METAMORPHOSIS OF SIREN.—I have already _ pointed out (NATURALIST, 1885, p. 245) that palaontology shows oS _ that the Batrachian order of Trachystomata, which embraces the ount for the curious condition which rved in the branchiz of the Sirens. The 1885.] Zovlogy. 1227 fringes are frequently in a state of apparent partial atrophy, and enclosed in a common dermal investment of the branchial ramus, or all the rami are covered by a common investment, so as to be absolutely functionless and immovable. This character, observed in the Pseudvbranchus striatus, gave Origin to its separation from the genus Siren. The character is, however, common to the Siren lacertina at a certain age, and the real difference between the genera depends on the different number of the digits in the two. I have been more than ever surprised on discovering that the functionless condition of the branchiz is universal in young indi- viduals of Siren lacertina of five and six inches in length; and lately I have observed that in a specimen of a little over three inches they are entirely rudimentary and subepidermal. I have, in fact, noticed that it is only in large adult specimens that the branchia are fully developed in structure and function. The infer- ence from the specimens certainly is that the branchiz are in the Sirens, not a larval character, as in other perennibrachiate Ba- trachia, but a character of maturity. Of course, only direct ob- servation can show whether Sirens have branchiz on exclusion from the egg; but it is not probable that they differ so much from other members of their class as to be without them. Neverthe- less, it is evident that the branchiz soon become functionless, so that the animal is almost, if not exclusively, an air-breather, and that functional activity is not resumed till a more advanced age. That Sirens may be exclusively air breathers I have shown by observations on a specimen in an aquarium which for a time had no branchiz at all. (See Jowrnal Academy Phila., 1866, p. 98.) In explanation of this fact it may be remarked that this atrophy cannot be accounted for on the supposition that it is seasonal and due to the drying up of the aquatic habitat of the Sirens, The countries they inhabit are humid, receiving the heaviest rainfall of our Eastern States, and there is no dry season. The only explanation appears to me to be that the present Sirens are the descendants of a terrestrial type of Batrachia which passed through a metamorphosis like other members of their class, but that more recently they have adopted a permanent aquatic life, and have resumed their branchie by reversion —E£. D. Cope. RECENT ADDITIONS TO THE Museum OF Brown UNIVERSITY.— Of late there has been made at this institution considerable effort to secure indigenous representatives of the animals which occur in the neighborhood of the college, and especially of such as are likely soon to be exterminated from the narrow bounds of Rhode Island, the most thickly settled State of the Union. Within a few weeks there has been secured a local representative of Bland- ing’s box tortoise (Amys meleagris), an animal well deserving a position in the cabinet, as both an early describer, Dr. John E. 1228 General Notes. { December, Holbrook, and the person to whom he dedicated the species, Dr. William Blanding, were graduates of this college. A representa- tive of the musk turtle (Avomochelys odoratus) is interesting in that it is a giant of its species, the carapax measuring four and one-half inches in length. An otter (Lutra canadensis) is also worthy of note, as it is an animal extremely rare in this region. This specimen was shot on the island of Rhode Island, and was large and in excellent condition, a state of health somewhat dif- ferent from that presented by an emaciated wild cat (Lynx rufus), captured in the more southern portion of the State, and probably the last Narragansett representative of its species, Perhaps the most interesting acquisition is that of a hoary bat (Atalapha cinereus). This animal, a beautiful female, was found a few miles from Providence, ona pine tree which had been recently felled. Dr.C. Hart Merriam, in writing of this species, says: “From its almost boreal distribution, and extreme rarity in col- lections, the capture of a specimen. of the hoary bat must, for some time to come, be regarded as an event worthy of congratu- lation and record. Although I have been fortunate enough to shoot fourteen, I would rather kill another to-day than slay a dozen deer.”—H. C. Bumpus. ZOOLOGICAL News.—Echinoderms.—Twenty species of Echini were, according to Mr. R. Rathbun, collected during the expedi- tion of the Alsatross in 1884. They include Homolampas fra- gilis and Aceste bellidifera, The latter species was only ob- tained by the Challenger in the vicinity of the Canaries, and was not found by the Blake in the Gulf of Mexico. The A/datross obtained it off the east coast of the United States, in 1497 fathoms. _ _ Crustaceans.—S. J. Smith describes Eunephrops bairdii, n. gen. and sp., a relative of Homarus (Proc. U. S. Nat. Mus. 1885, 167). The writer compares the species throughout with Wephrops nor- vegicus. The genus agrees with Homarus in the number and -water shells, with a revision of the Auriculacea of stern United States.

Mus., April 20, 1885) give a list of fishes collected in Iowa and Mis- souri, with descriptions of the new species, Motropis gilberti and Ammocrypta clara. S. Garman (l. c., April 23) describes as new Mylobatis goodei, from Central America; Dasybatus kuhli; D. varidens, from Hong-kong; Urolophus nebulosus, from Colima, Mexico; U. fuscus, from Niphon n Raya fusca, aiso from Japan; Raja senta, from deep water off the coast of Massachusetts, and R. jordani, from San Francisco, California. . S. Jordan and S. E. Meek (Proc. U. S. Nat. Mus., 1885, 44) give the synonymy and an analytical key of the American species of Exoccetus. The authors admit seventeen species, fourteen of which they place in Exoccetus, while the remaining three are placed in three other sub-genera. Most of the species have a very wide range. Æ. californicus is probably the largest species, A study of the skulls and vertebrz of twenty species of Ethe- ostomatinz or darters, made by D. S. Jordan and Carl H. Eigen- man, has induced the former to replace these little fishes in the Percide. “The Etheostomatine are near allies of the Percide, and should not form a separate family.” T. H. Bean (1. c. 73) describes Plectromus crassiceps, a single example of which was taken by the Adsatross at the greatest depth explored, viz., 2949 fathoms, and three other examples at lesser depths. The same ichthyologist describes Aspidophorides giintheri,from Alaska. A writer in the Bulletin of the U. S. Fish Commission states that he has been a witness to the destruction of just-hatched trout by mosquitoes. When a young fish came to the surface in the sunshine, a mosquito immediately transfixed its brain with its proboscis, and held on until the life juices were sucked away, when the dead trout floated down stream. The locality was the Gunnison valley, Col. Mr. J. A. Ryder has contributed to the Proceedings (U. S. Nat. Mus., 1885), a most valuable paper upon the development of viviparous osseous fishes. He quotes the observations of Girard and Blake upon the Em- biotocidz of the Pacific coast, and adding observations of his own upon the gravid females of three species, arrives at the conclusion that: (1) the hypertrophied hind gut of embiotocid embryos, clothed internally with crowded villi of great length, has probably a digestive function, enabling the young fish to assimilate the nutriment contained in the abundant fluid given out by the walls of the ovarian sac; and (2) that the great development of the interradial membrane of all the ver- tical fins, and the abundance and size of the blood vessels which supply that membrane, are mainly for the purpose of effecting respiration through the skin. In the later stages of development the protruding hind gut commences to diminish in size. In Gambusia patruelis each egg and egg-sac has its own indepen- dent supply of blood from the mother’s arterial system. The 12 30 General Notes.
