From American Natu- the expense of their lon- gitudinal diameter (Cas- tor, Lepus). The vertically laminated structure is evidently due to the crowding together of transverse crests by the same pressure which has given the crowns their oblique direction. In many genera the lengthening of the crown has included the lengthen- ing of the longitudinal connection between the transverse crests, as in Arvicola, Castor and Hystricide generally. In others this connection has not been continued, so that the crown is composed of prisms which are separate to near the base, as in Amblyrhiza and Saccomyide. In others, connection between the prisms has been lost by ccenogeny, as in Chinchillidee and Caviide generally. The latter families display also the greatest amount of crowding (Fig. 6). A peculiarity of the plication of rodent molars I am unable to explain as yet on mechanical principles. In genera which are isognathous, the inflections are of equal depth on opposite sides of both superior and inferior molars. In anisognathous genera Origin of the Dentition of the Rodentia. 11 the inflections are more numerous and profound on opposite sides of the molars of the respective jaws. Anisognathism in rodents is generally, as shown by Ryder, of the type where the inferior molars include a wider expanse than the superior, though this Dae aaa tavensis Cope, jaws, two-thirds apie om from Puerco a G Kos exico. Figs. a-d, lower jaw; e, upper jaw. Origin applies in some instances more to the direction of the roots rather than the position of the crowns. In Lepus the lower jaw is the narrower. The two types of anisognathism may be termed hyp- anisognathism (Lepus, Diplarthra) and epanisognathism (Caviidæ). The following genera display these characters :— Hypanisognathous. Tsognathous. Epanisognathous, Le Arvicola Hystricide. Capromys. Castor. Caviidee. In conclusion I will say that it is satisfactorily proven to my mind that nearly all of the peculiarities of the Rodent dental sys- . tem, and manner of mastication, are the mechanical consequences of an increase in the length of the incisor teeth. And the increase in the length of these teeth has been due to their continued use, as believed by Ryder. 12 Origin of the Dentition of the Rodentia. NOTE ON THE MARSUPIALIA MULTITUBERCULATA.—The struc- ture of the dentition of this suborder is in many respects like that of the Rodentia in the known forms. The incisors in the Plagiau- lacidee, Chirogidee and Polymastodontide have structure and func- tions generally similar to those of the Rodentia. The result in the form and function of the molar dentition has been similar to that observed in the Rodentia. The postglenoid process is prob- ably absent in these animals; in any case the mandible, or condyle, is rounded and is not transverse, Professor H. F. Osborn has pointed out to me that mastication was performed by a fore and aft movement of the inferior mo- lars on the superior, in Plagiau- lacidee. This was no doubt the case in the other families named. The resulting structure of the crowns is, however, different, and needs explanation. The molar teeth present conical tubercles in longitudinal series, two in the lower, and three in the upper jaw. The two series of the lower jaw alternate with Fie. 9.

This is demonstrated by the mutual wear of the tubercles seen in Ptilodus and Chirox (Fig. 7). The trituration was probably the same in Tritylodon, but in Polymastodon the increased thickening of the tubercles prevented their interlocking action in mastication. In this genus the tubercles slid over each other, and truncated the apices until in old specimens they were entirely worn away (Fig. 8 ce). In Meniscoéssus and Stereognathus we have an interesting illustration of the effect of the action of cusps on each other when under prolonged mutual lateral thrust. Their external sides have been drawn out into long angles in the direction of thrust, con- verting their transverse sections from circles to crescents. As the thrust is in the longitudinal Multituberculata, the crescents are PLATE I. red Ameba, Fig.2. Unusually large individual, Figs. 12.

In the selenodont Diplarthra, where the thrust is transverse to the line of the jaw, the cres- cents are longitudinal. That similar effects should accompany similar movements in two groups of Mammalia so widely sepa- rated as these two, is strong evidence in favor of the belief that the two facts stand in the relation of cause and effect (Fig. 9, Figs. b and d). ` DESCRIPTION OF A SUPPOSED NEW SPECIES OF ACINETAN, WITH OBSERVATIONS ON ITS MANNER OF FOOD INGESTION AND REPRODUCTION. BY ©. C. NUTTING. PoDOPHRYA COMPRESSA Nutting. [)ESCRIPTION :—Body illoricate, quadrate, wider anteriorly ; length from two to five times the greatest width ; compressed, about three times as wide as thick; the anterolateral corners occupied by rounded prominences, each bearing a fascicle of many suctorial tentacles which, when fully extended, are more than half the length of the body, and spiral or spirally marked when retracted ; posterior portion of body rapidly narrowing to meet the very short thick pedicle which is furnished with a sucking disk at its distal end; parenchyma densely and evenly granular contractile vacuole single, anterior ; endoplast oval. Length of body, 1-277” to 1-140”. Habitat. Fresh water. The above-described species has recently been numerous in a fresh-water aquarium in the Biological Laboratory of the State University of Iowa, where it was first noticed by Professor S. Calvin, who kindly delegated its investigation and description to the writer. ? In general appearance it somewhat resembles certain species of the genus Acineta, but the absence of any indication of a lorica excludes it from that group, and it is hence, with some doubt, placed in the genus Podophrya, with which it agrees in possessing distinctly capitate, fasciculated, suctorial tentacles only. It is 14 Supposed New Species of Acinetan. more like P. buckii than any other species heretofore described, but differs from it in possessing a distinctly compressed instead of cylindrical body, and in having a distinct, though short and thick pedicle. Whether this is a new species or not, the observations made on its food ingestion and reproduction are, erbane, of sufficient interest to justify publication. Although in two instances this animal was observed to capture ciliated Infusorians, its preference is decidedly for the Ameeba, which are abundant in the aquarium referred to. No sooner does an Ameeba come within reach of the long suctorial tentacles of the Acinetan than the dish-shaped suckers fasten firmly on their prey and draw it nearer to the body of the captor. On some occasions the capture. and subsequent ingestion were observed to be effected by one tentacle only, while on others many were employed in the operation. In one instance three Amæba were held and ingested at once (Fig. 1). The ectosare is soon punctured, how we could not discover, and almost immediately the body of the Amceba begins to decrease in size, its rounded outlines disappear, and in a short time after the capture it is reduced to a shapeless mass of flat and wrinkled ectosare, the endosare having been completely sucked away with the exception of the remains of diatoms and other objects too large to be drawn through the tentacular canal. The investment of ectosare is then discarded, and the tentacles withdrawn and made ready for other victims. The above observations were made with a one-fifth objective. A one-twelfth immersion objective yielded still more interesting and instructive results. As good fortune would have it, the Acinetan under observation almost immediately captured two Ameeba. One was caught at first by one tentacle only, which was then partially retracted, when several other tentacles curved around and grasped the prey in a close embrace, at the same time applying their several suckers, which seemed to be pressed out flat against the outside of the Amceba. In a few seconds the ectosare was pierced, when suddenly a rapid stream of granular protoplasm was seen flowing down the interior of the tentacles and into the body of the captor. So strong was this current that the particles flowing through the tentacles were forced in a rapid stream some distance into the parenchyma of the Acinetan, while in the body Supposed New Species of Acinetan. 15 of the Amceba the suction was so strong that particles were seen to rapidly converge from all directions to the points where the suckers were applied. After exhausting the contents of the Ameeba, one of the tentacles was seen to violently eject a stream of granular protoplasm. This was twice repeated, but the last time the act followed a slight pressure on the cover glass. On no other occasion was this ejection observed, but the query at once arises—Are these suctorial tentacles at times excretory in function ? This seems hardly credible in view of Huxley’s statement, “Solid food is not ingested through these tentacles” (Anatomy of Invertebrated Animals, Am. Ed., p. 94), but a subsequent observation removed this difficulty. On this latter occasion a Ciliated Infusorian rapidly crossing the field came in contact with one or more of the extended tentacles of the Acinetan, which immediately grasped the victim, and held it in spite of its violent struggles. Four incisions were made in the ectosare of the prey, and soon four rapid streams of protoplasm were passing into the body of the captor, rapidly exhausting the endosare of the Infusorian, although its cilia con- tinued in motion long after the animal was reduced to a mere fraction of its former proportions. During this process solid colored granules were seen to pass from the body of the victim through the tentacles and into the body of the Acinetan. This observation was verified upon at least one other occasion. The ingestion of solid food would seem to render an excretory organ necessary to the Acinetan, and if this is so it seems at least possible that the suctorial tentacles may serve the purpose. In regard to the manner of ingestion of food by the Suctoria, several of the leading authorities, including Maupas and Kent, hold that there is a double current of protoplasm in the tentacle, one of granular protoplasm passing into the body of the Acinetan, and another of colorless sarcode passing in an opposite direction. The writer has failed to find any evidence of the latter current, although his purely negative testimony is of little weight. Still the question might be pertinently asked: Why does not this colorless stream, pouring into the body of the victim, produce a current among the protoplasmic granules of the latter, which is directed away from the distal extremity of the suctorial tentacle ? A number of observations under favorable circumstances failed to disclose the existence of any such currents, although strong currents toward the point of incision were always distinctly seen. 16 Supposed New Species of Acinetan. The structure of the suctorial tentacles, as described by Kent, is that of a hollow tube traversed internally or externally by a spiral filament or granular crest, which appears as transverse striz when the organ is fully retracted. The writer has in vain attempted to assure himself of the correctness of this view as regards the species under consideration. It may be that a higher magnification would reveal the structure above alluded to, but a one-twelfth immersion objective’ used under favorable conditions of light, etc., and repeated observations have shown what seems to be merely a coiling and uncoiling of the entire tentacle, without any indication of the large central core figured in Plate xlviii., fig. 22, of Kent’s Manual of the Infusoria. The extension and retracting of the tentacle appears to be effected by the uncoiling and recoiling of the whole organ. In working out the method of reproduction of this species, the writer was at first entirely misled by discovering a specimen with embryos clustered around its anterior end as represented in fig. 4. The resemblance of this to the exogenous gemmation said to be common in the genus Hemiophrya, at least, and figured in Plate xlvii., fig. 8, Kents Manual of Infusoria, was so striking that there seemed hardly a doubt as to the interpretation ; and had no more observations been practicable, the species would have been described as reproducing by exogenous gemmation. The question naturally arises: May not others have been misled in a similar way, and may not exogenous gemmation be much more rare among the Suctoria than has been commonly supposed ? The life history of this Acinetan discloses the following stages, several of which merge almost insensibly into each other : lst. The parent form suffers the loss of its suctorial tentacles, which seem to shrivel up and gradually disappear. Fig. 3. 2d. Internal embryos of a round or oval shape make their appearance in considerable numbers in the endosare of the animal. Fig. 3. This process is accompanied and preceded by an unwonted activity in the granular protoplasm of the parent. 3d. These embryos escape through the anterior portion of the 1 Since writing the above, satisfactory observations have been made with a magnifying power of 1600 diameters, which have confirmed the view here advanced. Indeed there seems no room for doubt so far as the present species is concerned, whatever may be the facts in regard to others.

The ERE develop cilia and swim away as free, ciliated embryos. Fig. 5th. The Ea embryos become fixed to some object and acquire a triangular shape and a few (three or four) suctorial tentacles at each antero-lateral angle. At about this time the single anterior contractile vacuole appears. Fig. 6. 6th. The animal now grows longer, and gradually acquires more suctorial tentacles until the adult form is reached. The develupment is illustrated in figs. 7, 8, 9, 10, 11, none of which are hypothetical, each having been observed by the writer. Fig. 2. represents an individual of nearly twice the ordinary length, showing two transverse constrictions or markings of the ectosare. In this, as in most other specimens examined, the animal is largely obscured by various objects, which seem to adhere to its surface as if it were covered by a viscid substance. AN INQUIRY INTO THE STATE OF EARTH’S INTERIOR. BY IRA SAYLEs.! HERE seems to be a strangely broad difference between the conclusions of the geologists and the physicists on the condi- tion of Earth’s interior. This broad difference, therefore, invites every thinker to think for himself, and to conclude as best he may be able. As a thinker I enter the lists. It is manifest, from a bare inspection of the question at issue, that it demands both the inductive and deductive processes of ratiocination. Inductively, the fact of heat must be established, its extent established, and its persistence established: deduc- tively must its maximum be reached, it effects be reached, and the main results of these effects be reached. 1 U. S. Geological Survey. 18 State of Earth’s Interior. The geologist observes the lines of volcanoes girdling the earth as it is, and concludes that there must be a very extensive ocean of molten matter beneath Earth’s crust, to say the least. He turns his attention to the great continents with their moun- tain ranges, high plateaus and low broad valleys, and finds a somewhat astonishing degree of instability everywhere. Up- heavals and submergences are everywhere in progress. From these signs he argues, and that rightly, that there must be a trans- lation of matter from point to point beneath the surface. ‘This, he further argues, is consistent with fluidity only. A very legitimate conclusion surely. He takes another line of observations. He descends into the crust of the earth, and everywhere finds the temperature augmenting as he descends. Though this augmentation is constant, the rate of increment is not in all places the same. Still, however, this universal fact of increase of heat points straight to one conclusion, and corroborates the conclusion drawn from volcanoes, elevations or upheavals and submergences, viz., the temperature of liquefaction must be reached. All known rocks must become fluid. He turns to the record Earth has kept of her past history. There he finds that, in all geologic history, upheavals and sub- mergences have been common everywhere. He finds volcanoes have always existed. Moreover, he finds that great gaping rents have lacerated Earth’s adamantine bosom, and that through these huge rents vast streams of molten matter from the interior have gushed out over land and into ocean, spreading devastation wherever it flowed. | He now discovers that this molten condition of the interior has remained a persistent fact from the very earliest geological eras— undetermined millions of Earth’s years—zmillions, not thousands. Millenniums are but days in this great record. Interior heat has, therefore, been a persistent fact, and a persistent factor in geologic dynamics. , Moreover, these facts of upheaval and submergence, being universal, declare the universal fluidity of the great Earth-heart within. It is no circumscribed lake, as suggested by some. It is one universal mass of excessively high temperature. When, however, the geologist concludes that fluidity will be reached at about the point indicated by his observed rate of augmentation of temperature, along a descending line, his con- State of Earth’s Interior. 19 clusion is a nonsequitur, because he fails to recognize the changed conditions. As the line descends, pressure increases directly as the line lengthens. Now, one class of physicists claim that the incre- ment of pressure is persistently superior to the increment of heat but these physicists fail to notice that, when high temperature and high pressure are simultaneously exerted on the same rock, the character of the rock is changed, so that it becomes a far higher conductor of heat; and that, therefore, the incremental ratio for the heat very far exceeds the increment of pressure. Hence fluidity is assured ; but, this point once reached, another law comes in, viz. : The conduction and interstitial radiation become extremely rapid through the fluid mass, so that the temperature of the fluid is uniform with the temperature of the entire nucleus, and therefore no further augmentation can take place; but the ratio of pressure augmentation does not change. So that the increasing pressure soon overtakes the expanding power of the maximum heat, passes its limits, and solidifies all the nucleus within this limit. An ideal section through the Earth’s centre will, therefore, show the following : First, an outer solid envelope. Second, a semifluid envelope. Third, a fluid envelope. Fourth, a semifiuid envelope. Fifth, a solid nucleus, : No. 1 results from reduced temperature alone. No. 2 results from pressure and a temperature not quite suffi- cient for liquefaction. No. 3 results from a temperature sufficiently high to liquefy it under high pressure, and is the maximum temperature. No. 4 results from the increase of pressure so as to be just overtaking the expansive power of the maximum temperature. No. 5 results from a pressure so high as to overcome, completely, the expansive power of Earth’s maximum heat. At the centre of Earth the pressure, taking her general average, 5%, water being unity, is 7,180,593,750 lbs. to the square foot—a pressure so enormous that no known substance could fuse beneath it at Earth’s maximum temperature. Even hydrogen would be as hard as diamond at this maximum temperature of the internal nucleus. 20 State of Earth’s Interior. In the foregoing I decline to fix the limits to any one of the five regions of the section, and content myself with showing that they must all find a place, and in precisely the order named, and for the reasons named. All the above is strictly in accordance with observed facts, and as strictly in accordance with the laws of heat under pressure, both acting on the same matter at the same time. L have strictly refrained from special theories, and thereby have avoided personalities. SOURCES OF EARTH’S INTERNAL HEAT. First. The source of the primary heat of this internal mass was the arrestment of the cosmic motion of the atoms, by centralization under the laws of gravity and rotary motion of the mass about Earth’s axis. The free descent along the line of the axis must have resulted in an exceedingly high motion, and this motion was arrested at the centre, and in the growing nucleus, forming by their union. Second. The heat, thus evolved, initiated chemical action among these atoms thus rushing in. These were the sources of the original nuclear heat. When the mass was solidified, the heat was so high that very many of the superficial elements existed in their gaseous state only, forming an envelope around the central heated mass. Finally, when this central mass had so far lost its fiery energy as to permit their descent in a liquid state, they descended in the order of their respective heat-endurance. Now, in their turn, they began to solidify, and form the outer crust. Last of all, when the outer coating of this outer crust had reached the proper temperature, the water began to condense on the tops of all jutting peaks. Chemical action again set in as this water reached the alkine minerals. Here was another accession of heat. In due time Earth became productive of living organisms. Water began to tear down the incipient mountain ridges, carry the debris down into the young ocean, and there form the sedimentary rocks. The thin crust frequently bent beneath their accumulating weight, and brought these half-formed rocks within the influence of this internal heat. Chemical action again, to a greater or less degree, modified them, and they were hardened into rocks. Derivations of Mineral Names. 21 Finally, the sun burst through the primeval shroud, or swad- dlings of the new-born Earth, and began to lend its heat, to warm up the tender young bosom of Earth, and to fecundate her developing powers. Ever since that beginning, the sun has not failed for an instant, to pour in his genial warmth over some portion of Earth’s surface. This warmth, in the form of organic bodies, has constantly been sinking into the same surface; and, though we take little note of it, this amounts to a vast quantity, in geologic ages. I believe the foregoing is a fair summary of the case I under- took to investigate. It is only a summary. ON SOME INTERESTING DERIVATIONS OF MINERAL NAMES.’ BY F. M. ENDLICH. P bestowing a name upon any hitherto unknown substance, two factors mainly contribute to determine its character: The cir- cumstances attending the discovery, and the facts which have become known in relation to such substance. The basis upon which the new name has been formed may, in a general way, afford an indication of the scientific standard of its sponsor or of the period during which it became known. Probably the first thought which the sight of a new mineral, for instance, may occasion, will refer to its geographical origin or physi- cal appearance. ‘The second question might, appropriately, refer to its composition ; the third, to special characteristics and to its uses. We find, in point of fact, that a number of minerals were named by 1 As any dissertation upon a subject like the derivation of mineral names must, of necessity, largely be a compilation, I have refrained from making citations which would uselessly cumber the article. I have principally utilized the publications of Theophrastus, Dioscorides, Pliny, Agricola, Beudant, Ceesius, J. D. Dana, Domeyko, Estner, Gessner, v. Kobell, Linnæus, Matthesius, Naumann, Pape, Quenstedt, Wallerius, Weigand, and Werner, besides various lexico- graphic and poetical works. The manner in which I have presented the subject is essentially original, and a number of suggestions have been introduced which may throw light upon some doubtful points or furnish hints for further elaboration.—E. i 22 Derivations of Mineral Names. the ancients from the localities whence they were obtained, and this practice has been imitated with pious fervor during the last half century. While the method of commemorating the nameof the place which furnished the first specimens of any given species has certain advan- tages, philological as well as mnemonic, the nomenclature may thereby be rendered somewhat unwieldy, as Nertschinskite, Herren- grundite, Guanajuatite, and many others can testify. Similar in causal origin, but admixed with a certain spirit of appreciative cour- tesy, are those names which are derived from individual patronymics. Many scientific men, discoverers of new compounds, friends of mineralogists and chemists, and some persons of political rather than scientific prominence, have been immortalized by the bestowal of their names upon sound mineral species, Convenient and grace- ful as this mode of recognizing the services or merits of others may be, it is open to the same objections that apply to the use of geo- graphical names, in that the burden of carrying words like Macfar- lanite, Schwarzembergite, Zepharovitchite, and many others, is nearly as depressing as that imposed by the more recent terminology of organic chemistry. A system of forming names from some physical characteristic is, perhaps, not more rational than the preceding ; but it produces less bizzarre results, is apt to convey valuable hints, and tends to cause a desirable mental association of external features with the word designating the species. Thus, Antholite, contr. Gr. dydoc, flower, and Ato, stone; Asbolite, der. Gr. a6 20), soot, or Xanthoconite, contr. Gr. Savdoc, yellow, and xovec, dust, furnish a brief descrip- tion of certain leading, immediately apparent individualities of the minerals. Other properties, which may not be patent at first sight, give rise to names like Graphite, der. Gr. ypagw, I write; Helio- trope, contr. Gr. ýàoç, sun, and tpezw, I turn, the name given by Pliny to a variegated jasper, as he found that its red blotches and bands seemed to increase in size and brilliancy when held under water, in the rays of the sun. ! A concise review of the most prominent physical attributes of minerals show the following to have influenced the formation of mineral names in a marked degree: 1“ Causa nominis, quoniam delecta in vas aque fulgorem solis acci- dentem percussa sanguineo mutat.” Pliny, a.p. 70. Venice, 1557. Derivations of Mineral Names. 23 Form has produced Stylotypite, contr. Gr. 6rvdoc, column, and tuzos, form; Diagonite, der. Gr. dcaywyws, angular; and many others. WEIGHT is indicated by Barite, der. Gr. papuç, heavy ; Tung- stite, contr. Sw. tung, heavy, and sten, stone; and others. COLOR is a marked feature, duly recognized by names like Oyanite, der. Gr. xvavoç, sky-blue; Ruby, der. L. rubeus, red; Polychroilite, contr. Gr. zojvs, many, ypoa, color, and Adog, ` stone; and many others. Lustre is referred to Lamprophanite, contr. Gr. Aayzcoc, shin- ing, and gaevw, I appear; and many others. Light and touch alone will acquaint the observer with the special properties, but further examination will reveal others of equal importance. STRUCTURE is alluded to by a name like Fibroferrite, contr. L. fibra, fibre, and ferrum, iron ; and others. FRACTURE is referred to in Scolopsite, der. Gr. 6zodo¢, a splinter; and many others. : CLEAVAGE is of value in specific description and identification, as is testified to by names like Huclasite, contr. Gr. eù, well-easily, and xiuw, I cleave; Lowoclase, contr. Gr. 2łooç, oblique, and xiaw, I cleave; and many others. ODOR, TASTE, ELECTRICAL, CRYSTALLOGRAPHIC, OPTICAL, and other properties are duly utilized in the formation of distinctive names. After the physical constitution of a substance has been exhausted in furnishing points for discrimination, the most prolific field to turn to is that of chemical exploration. Under the appli- cation simply of heat, many minerals are curiously transformed. Often the changes exhibited are highly characteristic, and can well be utilized for taxonomic purposes. Scolecite, der. Gr. xole, a worm, describes a mineral which exfoliates into contorted, worm- like forms upon heating; Melanophlogite, contr. Gr. pedas, black and gioyeotos, burned, refers to a marked change of color under the influence of heat; Zeolite, der. Gr. Cew, I boil, designates an important group of allied minerals which bubble and intumesce upon fusion; Huosmite, contr. Gr. ed, well, agreeable, and 669 odor, is the name of a species which emits a pleasant odor when heated, contrary to the general rule. The chemical composition of a mineral is of the highest import- ance, and valuable hints as to its nature can be conveyed by the 24 Derivations of Mineral Names. name. Stercorite, der. L. stercus, manure; Arseniosiderite, contr. Gr. doGevexov, arsenic, and 6:9ypos, iron, and many others, con- vey useful information as to component parts. Every now and then the investigator finds himself somewhat baffled by the consti- tution of the mineral, or he obtains unforeseen results. Norden- skidld met a case of this kind by coining the name Thaumasite, der. Gr. avpaçw, I am surprised ; and Ekeberg by forming Automolite, der. Gr. aòtopołoç, deserter, in allusion to the fact that his speci- men had deserted other species to which its composition was sup- posed to be allied. Æschynite, der. Gr. 2%6yvvy, shame, records Berzelius’ protest against the inability of chemical science of that day (1828) to separate zirconic and titanic oxides. Peculiarities in chemical behaviour also find expression in the name: Tuchhydrite, contr. Gr. tayuc, quickly, and 5dw¢, water, refers to the rapid deliquescence of the substance upon exposure to the air. In some instances both physical and chemical properties which are especially noticeable, may be indicated by the name: Sideros- chisolite, contr. Gr. Gednpo0¢, iron, 6760s, split, and Xoc, stone, is the name of a ferric silicate with perfect cleavage ; Chaleophyllite, contr. Gr. yadxoc, copper, and guddoy, leaf, alludes to the foliated structure of a cupriferous mineral. The Greek language, singularly flexible and rich in clear defini- tions, has furnished the majority of descriptive mineral names ; Latin has been used more sparingly. Examples are not wanting where Greek and Latin have been combined in the same word, although this practice is to be deprecated: Pyraurite, contr. Gr. up, fire, and L. aurum, gold (“ molten gold ”); Cupraphrite, contr- L. cuprum, copper, and Gr. ’agpog, foam, is a literal rendition of the prior G. Kupferschawm. Languages of our own day have like- wise yielded their quota to the list of mineral names: Muromontite, contr. L. murus, wall, and mons, mountain, is the Latinized form of G. Mauersberg, where the mineral was found ; Leucopetrite, contr. Gr. jevxoc, white, and zerpa, cliff, translates the G. Weissenfels. The G. Olivenerz of Werner, 1789, has become Olivenite, on account of its color (G. Olivin), and the popular term of Carmine- spar has evolved into Carminite. The successful attainment of uniformity in mineralogical nomen- clature is largely due to the rigid stand taken by Professor James D. Dana, the eminent American mineralogist. But a few centuries since, all matters pertaining to chemistry and mineralogy were in the Derwations of Mineral Names. 25 hands of alchemists, apothecaries, and a few doctors of medicine. For the production and application of meaningless names, these gentlemen are to be commended. The principal metals were called by the names of the “ heavenly bodies,” as Chaucer has rhymed it: “ Sol gold is, and Luna silver we threpe ; Mars iren, Mercurie quicksilver we clepe.”’ Others were endowed with terms like lupus metallorum, wolf among metals, for antimony; diabolus metallorum, the devil among metals, for tin ; spuma lupi, wolf’s spittle, for wolfram, ete. On the other hand, we are indebted to the alchemists for many chemical terms which are now indispensible—e.g., alcohol, alkali, crucible, and many others. The influence of ancient Arabic magic and occult science is plainly discernible in the Oriential source whence the alchemists chose their names for various 'substances. By so doing they removed the comprehension of their terminology far beyond the reach of laymen, and even of many learned philolo- gists and ecclesiastics, and added to the attractive mystery which enveloped their labors. Linneus, about 1730 to 1740, attempted to introduce binomial nomenclature for minerals; but the science was not ripe for it in his day. His efforts were in the right direc- tion, tending, as they did, towards systematic classification ; but the means were not at his hand to use proper discrimination. The material was too crude; the analytical knowledge too insignificant. To-day some of his names cause a smile—e.g. (Edition Gmelin, 1773), his genus Silex contains the species Silex achates, agate, and the subspecies Achates arenomorphos, “with drawings of constella- tions ;” A. zoomorphos, “with drawings of animals ;” A. techno- — morphos, “with drawings which the imagination transmutes into works of art,” ete. Few of the mineral names given by the alchemists have survived in their original application, but their researches have enriched our fund of available words. Quicksilver (mercurius vivus) has been handed down unchanged ; but Marcasite, for instance, now desig- nates a compound of sulphur and iron, while it was used for bis- muth (mareasita argentea) originally. Besides the planets, mytho- logical deities have been called upon to furnish names for the ever-growing list of mineral compounds. Thorite perpetuates the name of the mighty Scandinavian god, the son of all-powerful Odin and the Earth. 26 Derivations of Mineral Names. In addition to the features which have been touched upon above, as affording especially noticeable suggestions for the construction of mineral names, there are a few others of sufficient prominence to command attention. MODE OF OCCURRENCE is often associated with the genesis of the substance; hence of importance. Limnite, der. Gr. deyvy, marsh,, alludes to the origin and formation of bog-ore. Alunogen, a curious cross between Fr. alun, alum, and Gr. yevvaw, I produce, refers to the generation of the mineral from decomposing Pyrite. RESEMBLANCE to other species may provoke errors of identifica- tion, and gives rise to names like Apatite, der. Gr. dzaraw, I deceive, on account of its resemblance to Aquamarine. CoMPARISON with allied compounds is expressed in names like Miargyrite, contr. Gr. peewy, less, and dpyupos, silver, whereby the fact is indicated that this mineral carries less silver than other closely related species. Mimicry of natural objects is readily perceived and made the basis for a name. Thus, Ophite, der. Gr. dgery¢, snake, is applied to some varieties of Serpentine (snake-stone) because of snake-like markings. Botryogen, contr. Gr. forcvs, a bunch of grapes, and yevvaw, I produce, explains itself. DECEPTION is recognized in minerals whose occurrence or genesis would lead to the inference of a different composition than they possess in reality. Sphalerite, der. Gr. @gaiepos, treacherous, was so named because it carried very little silver, though generally associated with argentiferous ores. THE USEs to which a mineral may be put also furnish hints for its name. Agalmatolite, contr. Gr. dyahua, picture, and edtoc, stone, is the material utilized by the Chinese in carving out numerous small objects. A rather pathetic appeal reaches us through the name of one of Breithaupt’s species: Monacite, der. Gr. povafw, I am alone. It is of very rare occurrence. Apart from the mineral names which have been formed for the purpose of expressing a definite idea, there are some which are of interest on account of their origin, their philological relations, or their application ; others claim attention by virtue of the mutations they have undergone, or by their associations. Derivations of Mineral Names. 27 1. A few names are of obscure origin, and their etymology is imperfect : ZincitE.—The O. H. G. form of zincho, zinco, may, perhaps, be perpetuated in the M. H. G. zinck (Weigand) and H. G. Zink, Sw. zink. Zincho signifies a white spot in the eye. The origin of the word is by no means clear, but is probably German or Indo- German. Apparently it is related to G. Zinn. (See Stannite.) The metal zinc seems to have been first described by Paracelsus, about 1528. N. L. zinewm. QUARTZ, the name of the most widely-distributed of all minerals, suddenly appears in M. H. G. as quarz, with a plural querze which latter it retains until the middle of the sixteenth century N. L. quarzum (Agricola, 1546); quartzwm (Wallerius, 1747). No older root seems to be known. G. Warze, Gewarz, warty excres- cence, has been suggested. The form Quertz. occurs as late as 1743 (Bergwerck’s Lexicon), and Qudrtzel at that time signified a chip of rock, or one which flew into the miner’s eye. The word probably originated among German miners, as the mineral is one which might readily escape special notice, unless encountered in the form of veins. Quartz-crystals were known as Kristalle in M. H. G. It seems possible that quartz should be related to Engl. quarry, to L. quadrus, G. quader, Sw. quatersten, and other words pertain- ing to the cutting of blocks of stone—eg., L. quadratarius, stone-cutter. M. and N. L. quartatio, separation of precious metals from other minerals, might have been corrupted into quarts or quartz, in allu- sion to the fact that quartz, when it forms the matrix, generally admits of a sharp definition of “ore” or “ metal” and “ stone.” ANTIMONY.—It is a difficult matter to trace the origin of this word satisfactorily. We know that the classical Greeks and other ancient nations possessed the antimonial sulphide (Stibnite), which was extensively used for cosmetic purposes. The substance was powdered and applied to eyelids, eyebrows, and underneath the ‘eyes, with the intention of making the latter seem larger and more brilliant. This classical custom has survived to the present time. By the Greeks the word Gryp, or Grife, was used to designate the mineral employed. The word is not of Greek origin; possibly Egyptian, probably Arabic. From this the Romans borrowed -stibnum, which has remained the Latin name of the metallic element to this day. Metallic antimony, though known to the ancients, was t 28 Derivations of Mineral Names. first described, as to its properties, by Basil Valentine, near the year 1400. Antimony, as a word, fails to comply with the Gr. r:e in all but the tim. That this should be sufficient to establish a connection cannot be claimed, but it indicates that both names may well have a common origin. It is possible that the first syllable, an, may be a modification of the Ar. article al, in which case the reference of the word to an Arabic origin would seem justified. An old Arabic name for Stibnite is al-kohl (whence our alcohol) ; but as this seems to refer to the powder, rather than to the crude mineral or metal, there may have been another root. The Ar. al-ithmidun is regarded as the source of antimony, the latter being a rather exaggerated corruption of the former. Another derivation brings it from the Ar. athimar, the name of the metal. (Const. Africanus, 1100.) A forced derivation is obtained from Gr. dyze, against, and M. L. monachos, monks. Basil Valentin, the monk, fed some antimonial compound to his pigs, and they grew fat upon it. He tried the same dose upon his cloister brethren, and they died: hence the supposed origin of the name. It remains a coincident that the French word for antimony introduces an i in antimoine, _ and that Fr. moine means monk. BismMuTH.—The origin of this word is not very clear. It was first used in Germany in the later middle ages. A common expla- nation assigns it to O. H. G. wesemot, contr. wese, meadow, and mot, damp ground, swamp; but, aside from the similarity of sound, there seems to be no relation between the two words. Another root has been claimed in the H. G. word Wiese, meadow, as some old writers claim that the colors which the metal assumes upon cooling after fusion are varied and beautiful as those of flowers on a meadow (sixteenth century). The metal is white, and often assumes iridescent colors after melting. During the sixteenth century German writers speak of it as Bis- mut, Bissmuth, Wyssmuth, and Wissmuth. At the same period its Latin mame was bisemutum (Agricola, 1546). This latter may be merely an amplification of the German term, or it may be com- posed of the L. words bis, twice, and emuto, I change, in allusion to the crystalline and color changes undergone upon fusion. About 1400 the word was bismuthum. A more plausible explanation of its origin lies in the derivation from M. H. G. wiss or wyss, white, the color of the metal. There Derivations of Mineral Names. 29 are traces of an O. G. root mut, which refers to ground, earth, and, in Swedish, seems to indicate ore,mine. From this root the second syllable of the word may be derived. If the name was given by miners—and there is every reason to suppose that it was—then it was, in all probability, a descriptive term, denoting either appearance or some peculiar property. The above derivation would, therefore, determine the meaning of the word as white-ore, or some kindred term. Sw. vismut; later, bismut. The change from w or v to initial b is due to Latinization. 2. Besides the names of decidedly dark origin, there are some which have changed considerably, in their journeys from nation to nation, through the course of centuries. It is interesting to note in these, as well as in other instances, that the words have generally reached Scandinavia through Germany, England through France. EMERALD is the modified form of Sansk. marakata and samaraka. In Pers. the latter becomes zamarrad; in Ar., zamamth ; in Gr., papaydos and 6yapaydos, with the verb 6uapaydeu L., lucere, to shine brightly. In all of these forms, as well as in the L. smaragdus, the initial s-sound and the final d-sound have been preserved. The Gr. and L. form has persisted in the G. and Sw. Smaragd ; in It. it is changed to esmeraldo; Sp., to esmeralda. O. Fr. retained the prefixed e and the l, using the word esmeraulde ; sub- sequently this was modified into emeraude. Our English name follows the latter closely in O. Engl. emeraud and emeraulde, but has retained the / in emerald: oa a’; ol E “ the semes echon Was set with emerauds one and ore.” — Chaucer, 1340-1400, and, later : “ Would emulate the emeraulde-like grass.” — Stirling, 1614. Zuapayðoş was mentioned by Herodotos, about 450 B.c. Usu- ally the name was applied to varieties of aquamarine, rather than to the emerald, although the ancients were familiar with the latter. <. . . « © 6papaydov Atov laurovrtoç tas vuxtas psyatos.”” —AHerodotos, II, 446. 30 Derivations of Mineral Names. Pliny describes it as surpassing everything that exhibited green color in the loveliness of its shade. Emery, although so near emerald in sound, has a totally differ- ent origin. Its Gr. ancestor is 6uvpes or Eyypes, der. Gr. Cuvprfer, to polish by rubbing. Dioscorides uses 6y:p:¢. In H. G. the word resembles the Greek phonetically—Schmirgel, Sehmergel, or Smirgel ; Sw. smergel. In It. the L. smiris changed to smeriglio; N. L., smeriglo (1602), smeriglius, smirillus (1610) ; Sp., esmeril; Fr., emeril, later emeri—whence Engl. emery. It will be observed that a number of words prefix an e in French and Spanish. This is probably due to the use of the respective masculine articles le and el. Thus, It. smeriglio becomes le smeril, and subsequently esmeril or Pemeril. In Sp. the article el is pre- fixed and the / finally eliminated. Changes of gender are of rather frequent occurrence in the history of mineralogical. nomenclature, , so that French or Spanish names which show an initial e but are now feminine may well have been masculine at some early period. CALAMINE has often been accredited to Gr. xadapoc, L. calamus reed (Agricola, 1540), a name which might appropriately be given to some varieties on account of their structure. This derivation is all the more seductive, as a genus of plants, Calamites, has the same ancestry. The name, however, seems to be due to Gr. xadpeca, L, cadmia, G. Galmei. Gr. xadpeea, or xadpra, is used by Dioscorides, about A.D. 30, in. writing of a mineral, and was supposed to have been derived from the legendary Kaðyoç, a Pheenician, who came to Greece and first introduced smelting there ; later by Pliny and others, in the form of L. cadmia.' In It. it remained cadmia, but in the transition from It. to Sp. and G. the d changed to J, as is frequently the case, and we find Sp. calamina, Fr. calamine. Alb. Magnus uses lapis cala- minaris (1280). G. calmei appeared in the beginning of the six- teenth century ; not long after, the initial c of calmei was replaced by the H. G. g, producing galmey (Cadmia Jossilis, Gessner, 1565); later, Galmei ; Sw., gallmeja (1750). The name was rather indis- criminately applied as “ Cadmia metallica cinerea,” in the sense of “ein natiirlicher, grawer kobelt” (a natural grey cobalt), shows (Gessner, 1565). 1 Namque ; ipse lapis, ex quo fit aes, cadmia vocatur.” -2 A. Caesalpinus, Aretinus, 1602, says: ‘“‘Calaminam, seu lapidem Calaminarem, vulgo, Giallaminam, . . . . Arabes Climian vocant.” Derivations of Mineral Names. 31 GARNET.—From the color and size of the grains—in which latter form garnets were first found—they were originally compared to the seeds of the pomegranate (malum granatum), and received the name lapis granatus therefrom (cfr. Magnus, about 1280). L. granum, grain, is the root, although granatus, having the mean- ing of grains or seeds, was used by Cato about 200 B.c. In G. this has perpetuated itself as Granat, from M. H. G. to the present time ; in It., granato ; Sp., granate ; Fr., as grénat. Transposition of the letters forming Fr. grénat furnishes the Engl. garnet. It is curious to note that, while the Engl. compound word pome- granate (G. Granat-apfel) retains the original pai position of gr, this has been changed in Engl. garnet. ORPIMENT is a corruption of L. auripigmentum, contr. L. aurum, gold, and pigmentum (from L. pingere, to paint), color, used by Pliny, about A.D. 70. O. H. G. orgimint, M. H. G. orgemint, orperment, opriment, opirment, prepared the way for H. G. Operment, in which the r of aurum has been entirely dropped and one inserted after the p. Sp. oropiment, It., Fr. and Engl. retain the r in orpimento and orpiment: ‘ The first spirit quicksilver cleped is, The second orpiment.’ —Chaucer, 1340-1400. Zircon.—The derivation of this name is somewhat peculiar. For many years the Island of Ceylon furnished gems and half gems. Some of the latter were utilized to imitate their more valu- able associates. Such were called jargon in French? Among them were some colourless crystals, and others of yellow and reddish shades, which turned white and clear under the application of heat. These were especially desirable for the imitation of diamond, and to them the name jargon finally attached itself almost exclusively. In the middle of the last century Linnzus describes this mineral under the name of jargon in such a manner that its identity can be established. He states (Ed. Gmelin, 1777) that the (presumably German) jewelers’ name for reddish jargons which turned colorless in the fire was “ Cerkonier” (Cerkon), and that they exhibited the fire and lustre of the poorer quality of diamonds. In 1783, 1 Linnæus mentions Fr. jargon and It. sargone, yellow diamonds— the inferior class—whence the name may have been transferred to the stones which counterfeited the valuable gem. ” 32 Derivations of Mineral Names. Werner, the famous mineralogist of Freiberg, produced the name Zirkon for this mineral. In ordinary parlance, the zircon is known as jargon in France to-day, so that the accepted scientific name is to be regarded as a corruption of the popular one. Jargon, in the above acceptation, means counterfeit, wrong pre- sentment, but the word is now more particularly used in the sense of gibberish. The remote origin of jargon may connect it with Gr. yapyapttw, I gargle—make a noise in the throat—and L. garrio, chattering (whence Engl. garrulous), gossiping. In It. it has changed to gergone and giargone (de Boot, 1636); Sp., jerga, jeri- gonza; Fr., jargon ; O. Engl., jergon ; Engl., jargon (der. A.-Sax. girran, chattering [?] ). “ He was al coltish, ful of ragerie, And full of jergon as a flecked pie.” — Chaucer, 1340-1400. “ Their mystic cabals and jargones.” — Butler, 1682. In these instances the meaning of jargon is somewhat different from that of to-day. (To be concluded.) ABBREVIATIONS. A. D., Anno Domini, in the year | M.H.G., Middle-High German, A. of our Lord.

Sea-Side Study on the Coast of California. 33 SEA-SIDE STUDY ON THE COAST OF CALIFORNIA. BY J. WALTER FEWKES. ITH the increased facilities for travel, the number of Eastern naturalists who visit California to collect marine animals with dredge and dip-net, will also increase. Those who are interested in the marine zodlogy of the Pacific Ocean will seek advice of those who have already studied there, as to the best place to carry on their work with profit and with least loss of time. To such the experiences of the author and his convictions as to a good place to prosecute this kind of work on the California coast may not be without interest. A second and most important object in writing this paper isa plea for the establishment on the Pacific coast of a marine labora- tory, where biological research of all kinds shall be carried on. It is a great pleasure to a marine zodlogist to pull the dredge or drag the Miiller’s net! in waters where these implements have never been used. It is a source of real satisfaction to study a marine fauna in which a majority of the animals captured are new to science, and one may be pardoned if he speaks with enthusiasm of the results of such study. Such places are many, and opportunities of this kind not so rare that naturalists are obliged to enter upon long journeys to reach them. Even upon the coast of New England where marine zodlogy has been cultivated for many years, the work can hardly be said to have more than begun, while great groups of marine animals have hardly been identified. A preliminary study, however, has been made, and, thanks to the researches of our naturalists whose names, known to all zodlogists, it is not necessary to mention, the facies of our New England marine fauna is known. When, however, we turn to the western shores of North America, to the coast of California, Oregon and Washington Territory, we find a shore where this study is yet in the first stages of growth, for ' The net used in surface fishing. So called because so successfully used by the great naturalist, Johannes Müller. — 34 Sea-side Study on the Coast of California. here the dredge has been but little used, and the revelations of the Miiller’s net are almost unknown. The marine animals of the Atlantic have been fora long time the continuous study of marine zodlogists. Those of the bays and seas of Europe and of the Eastern waters of the United States have been so sedulously investigated that it may be said that almost our whole knowledge of animals which live upon the surtace of the ocean, is derived from this source. The Pacific Ocean, from its remoteness from centers of zodlogical activity or other causes, is almost wholly unexplored, and while good beginnings have already been made, even the facies of the surface fauna of the Eastern Pacific is practi- cally unknown. The coast of California, throughout its great length, offers extra- ordinary advantages for a study of this department of marine zoöl- ogy, and yet, with one or two exceptions, the use of the Miiller’s net, early introduced on the Atlantic waters of the United States by the elder Agassiz, and so successfully used for so many-years by sev- eral naturalists, is unknown on a coast washed by the largest ocean on the globe. The use of dredge and net has a great future in the study of the marine fauna of California. In the first phase of the study of the surface life of the ocean, the work was almost wholly the result of individual enterprise, unaided by government or university appropriations. Naturalists visited, during their vacations, the North Sea, Nice, Villa Franca, Naples, or Messina, accompanied by students, and in that way the foundations of this knowledge were laid. The work which they did has been the admiration of naturalists and their verdict forms a part of the history of science. But in this pioneer work the older naturalists had difficulties to contend with which one who visits the well-appointed stations which havearisen in later years on the Med- iterranean, knows nothingof. The places which offer the best locali- ties for collecting were not known, practical fishermen had to be shown the animals which were wanted and how to collect them. In most cases the naturalist himself had to spend many hours on the water collecting, and precious time was used for what might have beén done by others. The naturalist was investigator and col- lector, and his laboratory, oftentimes the room in which he lived, or some place poorly lighted and little fitted for his work. While the combination of collector and investigator in one and the same person * — 1 I know of no more absurd position than that of the closet naturalist who despises the collector, or of the anatomist or histologist who belittles Sea-side Study on the Coast of California. 35 is sometimes an advantage, it is true that much work can oftentimes really be aceomplished if these two functions are performed by specialists. In no short time there arose in Europe, in the best localities on the coast, permanent laboratories with all appliances for continuous work. It was no longer necessary for the investigator to explore the coast to find out where the best collecting grounds are, or to make arrangements with fishermen and educate them for the work, i He was no longer obliged to spend months in search of some animal whose favorite habitat and breeding place must be discov- ered before research upon their anatomy, embryology, or histology, could be carried on, but all these difficulties were reduced to a min- imum. Well-endowed stations with equipments have arisen. Continuous observations in the same place have taught when and how certain animals can best be found; and the naturalist now economized time and money, while by working in the established laboratories he finds himself associated with others interested in the same work. Mauch praise must be given to the pioneers in this study, and the younger school of naturalists, from the vantage ground which they occupy, are apt to overlook the difficulties which those before them encountered. On the Atlantic coast of the United States we have passed or are passing into a second stage in the development of the study of marine zoölogy. While the older American zoölogists in their earlier days sought the shore with no help from state or college, we now have well-equipped laboratories bringing many other advan- tages. The contributions to science made by the U. S. Fish Com- mission, Mr. Agassiz’? Newport Marine Laboratory, and the Chesapeake Marine Laboratory, tell of the harvest which may come from the second stage in the development of marine research in America. While these stations have accomplished a great deal in carrying on the study, much is done every year by summer schools of natural history and by individual naturalists unconnected with any of these stations or schools. Professors of our colleges visit the shore with pupils, and in several instances have made extended investigations wholly independent of public or private marine lab- oratories. These efforts have much to recommend them, but are the systematic zodlogist. It is, as suggested to me by a well-educated naturalist for whom I have great respect, like the hands of the clock say- ing to the pendulum, “ I have no need of thee.” 36 Sea-side Study on the Coast of California. often hampered for resources, as they involve in many instances large outlays for boats, dredges, and fishermen. Moreover, some of the best localities for the study of marine zodlogy are visited by these private parties. On the Pacific coast the study of marine zodlogy has entered upon the first phase of the development, but has not passed to the second. No marine station has yet been founded there. The naturalist who seeks those shores must himself discover the best place to work. He finds no fisherman familiar with his needs, and must educate them in the use of the dredge. In short, feels that he is veritably a pioneer, if he has in mind the use of the net and dredge. The delights and results of his work, however, are those which come to the first worker in a new field. When I had decided to visit the California coast to study its marine fauna, the first information which I sought was where is the best place to get the best results in the shortest time? The first question which was asked local naturalists was, where is the best place for the study of marine zodlogy on the coast? I received in most cases no satisfactory answers, and perhaps I ought not to have expected them. Prominent marine zodlogists in Europe differ in their estimates of the value of localities on the Mediterranean as collecting places. Many say Villa Franca, others Naples, others Messina. On the coast of New England some of our prominent naturalists prefer Newport, others Wood’s Holl, others Eastport. Every one has a preference, but it is a known fact that there are some places on our coast which no one recommends. The coast of California, however, has been so little studied that even the satisfac- tion of knowing the prominent places was not allowed, as I could find almost no one who had used the dredge. The first thing nec- essary there was a kind of te ie dest exploration to discover a good. place for work. It may be of advantage to others who have in mind a visit to the Pacific coast for work similar to that which I carried on to know the result of my experiences. I have used the dredge and Miiller’s net at Santa Barbara, and among the neighboring islands, at Port Harford, Santa Cruz and Monterey. I can recommend any of these places for this kind of work; but I prefer the Bay of Mon- terey, and think if ever a marine station is founded on the coast of California, no better site can be chosen north of Point Conception than on this beautiful bay. I am sanguine enough to hope that in Sea-side Study on the Coast of California. 37 time two marine stations will arise on this coast, in which case the Bay of Monterey and either San Diego' or Santa Barbara might well be chosen. There are several desiderata which influences the marine zodlogist in his choice of a working place upon any shore. The first, per- haps the most important one, is whether the collecting is good, whether there are many animals at the place recommended. ‘This is an all important, but it is by no means the only question, Of what use is it to a naturalist if he can stand on a wharf and see a wealth of surface life float by and can get no boat to collect it? This might seem an absurd condition on the coast of New England where every coast hamlet has so many boats; but I have been in a considerable village on the coast of California where one or two large, undesirable boats were the only boat facilities of the place. In Santa Barbara, which has the reputation of being a boating place, you can count on your two hands the number of small boats for rent. Several conditions have brought about this result. In most places the wharf is built out from a beach on which the surf is continually breaking. There is no protection for boats, and the fondness of the New England coast people for the water is not known. Although so many strangers come to Santa Barbara, there are few pleasure boats and no skippers. Compare this condition with the wharfs, for instance, at Newport or Eastport. It is not alone necessary for the marine zodlogist that he should have a good collecting ground and a boat, but he must be able to reach the coast easily. If he studies animals alive his laboratory must be on the shore, for pure water must be continually supplied, and the live animals of the fragile nature of many marine creatures cannot be carried for long distances without harm. It is best if his laboratory is as near as possible to the water. The New England fishing towns, many of which arose as fishing hamlets, lie upon the very shore, and accommodations are easily found to satisfy the haturalist’s wants. That is not always the case, however, in towns Which have originated like those of California, The holy fathers Who were the founders of Santa Barbara and Santa Cruz did not look to the sea for a livelihood. The first settlers were not fisher- * Unfortunately, circumstances prevented my spending any time at San Diego in the study of surface animals or in dredging. I confess my ignorance of its advantages, which from what I could learn from others and my own superficial examination of the neighboring coast, must be very great. ¢ 38 Sea-side Study on the Coast of California. men, nor was commerce at first of great importance. As a result many of the coast towns are separated by some distance from the wharf or landing-place. One knows how much discomfort this may mean to a naturalist if he has trudged along over a mile from the wharf to the nearest house he could rent for a laboratory, with a water-bucket filled with the products of surface fishing by night, and if twice a day he has been obliged to replenish the water by a similar tramp. ‘Time is lost which might be employed for work, and the naturalist cannot watch and take advantage of the ever changing conditions of the sea and wind if his workshop is a mile or more from his boat. The naturalist who studies ichthyology,' and who visits the fish markets when the fishermen return from their nets, does not feel these discomforts which the naturalist who must collect for himself has. A good collecting-place, boats, and ready access to the water are three requisites in a choice of a good station for marine work. They are the great difficulties which the pioneers in marine zodlogy have always encountered. The naturalist who works in a well- equipped station, with trained fishermen for collectors, knows little of these difficulties. Until, however, a zodlogical station is founded on the coast of California these three things, unfortunately or for- tunately, must have great influence in his choice of a working-place. The Eastern zodlogist, who has worked on the Atlantic, encoun- ters several physical characteristics on the coast which are new to him. The absence of those nooks and indentations of the coast, pockets in which floating life is driven by the currents and winds, is a marked feature of the coast line. Many of the harbors are open roadsteads upon which a surf is continually breaking. While this feature is in some respects a disadvantage, it is in others an advantage. | Along the coast in many places, as at Santa Barbara, a zone of floating kelp undoubtedly prevents many floating animals from being washed to the shore. This kelp extends for miles along the coast, and it is only where the bottom sinks immediately to a great 1 In this article I have considered more especially the needs of the student of the marine invertebrated animals, as the largest share of oceanic life belongs to these groups. In many instances it will be found that the needs of the ichthyologist are very different. They have little to do with dredging, but the student of the embryology of marine fishes and their younger stages will appreciate what is desired in work with the Miiller’s net. . Sea-side Study on the Coast of California. 39 depth near the shore that it is absent. While it may shut out effectually many floating things from the neighborhood of the wharf, it shelters in its fronds many others; while the root-like attachments to the rocks harbor many interesting animals. Between the zone of kelp and the shore was not found to be a profitable dredging-ground. The interval appears to be filled with decaying fragments of the kelp, and the dredge comes up filled with this debris. Dredging in the belt of the kelp itself is impossible. The best dredging at Santa Barbara is in the channel about four miles outside the outer border of the kelp. The rocks in places entangle and catch the dredge, and the bottom is, except in one or two places, very rocky. Off Punta del Castillo, near Santa Bar- bara, there is some good ground for dredging, but it is hard to pulj the dredge on account of the many submarine rocks. From Santa Barbara across the channel to the Santa Barbara Island, there are many rocks, but the dredging is good in places. The vicinity of Carpenteria is the best place of all about Santa Barbara for dredging, The island of Santa Cruz,! one of the most beautiful islands of she Santa Barbara group, offers fine surface collecting. The dredging is difficult on account of the many submarine rocks and the depth of the water. To one visiting the island for zodlogical study no better anchorage can be found than a small cafion resorted to by otter hunters near Punta Diablo. The shore collecting on the beach at Santa Barbara is poor. At Punta del Castillo many interesting animals were found. Santa Barbara on the whole offers good facilities for the study of marine zodlogy. The fauna of the shore is not rich, but it is varied, and that of the neighboring islands is all that could be desired. The surface fauna of the Santa Barbara channel is very rich and dredging in it is excellent. I do not believe the shore at Santa Barbara can compare with that to the south by Del Mar and San Diego as a collecting place for the naturalist, but the dredging is good and the surface collecting all that could be wished. ' Especial interest is attached to a study of this island from the curious distribution and character of the flora as compared with that of the main land. This island, continental to all outward appearances, has a more peculiar flora than the Bermudas, although they are only a little over twenty miles from the shore, while the Bermudas are five hundred. No more interesting problems can be studied in regard to the geograph- ical distribution of animals than the character of the life of the islands near Santa Barbara. 40 Sea-side Study on the Coast of California. In order to study the conformation of the coast of California be- tween Santa Barbara and the Bay of Monterey, and to form a judg- ment of the advantages of the several ports for natural history work, I took one of the smaller steamers of the Pacific Navigation Com- pany, which touches at the several landings. I did not dredge in all these places and my judgments may be more or less hastily made. They are thought to be of some worth.

It would be impossible to get boats and fishermen on this unknown coast. San Simeon is a dairy town and few fishermen are found there, although there is an easy communication with San Francisco and. other prominent ports on the Pacific, by means of the Pacific Steamship Company. Santa Cruz presents many conditions which render it a good place for the marine zoölogist to work. There are many fishermen and boats can be had at reasonable rates. It has good hotels and board- ing-houses contiguous to the landing-places. There is a good sandy beach and near by rocky cliffs both with characteristic life. The Sea-side Study on the Coast of California. 41 dredging is good. The neighboring town, Soquel, when there are many fishermen, presents many facilities for the naturalist. Collecting on the piles of the wharf is not as good as at Santa Barbara. There is no belt of kelp forming a thick zone shutting out the floating genera from the shore. The phosphorescence is at times superb, but surface collecting in the afternoon was found to be next to impossible. The beach is more sheltered than that of Santa Barbara, but it rarely happens that the surf does not break on the shore. Sheltered caves or natural pockets in which floating life are caught are rare. Taken all in all, Monterey ! is one of the best places on the coast of California for a naturalist to station himself for a study of the marine life of the Pacific. It may not be the best, but experience has taught me that it is one of the best, and a visit there by a natur- alist will be amply repaid by novelties if his object be research. The surface fauna is rich and there is good dredging. There are boats of all sizes and many fishermen. ‘The city lies near the shore and one is not forced to waste time in reaching the wharf from the hotel. The means of communication with the outside world are easy. I find, on reference to my note book, that many of my choic- est specimens came from this locality. Stimpson found the bay of San Francisco nearly barren of a varied marine life except at its entrance. This condition he ascribed to the admixture with its water of the turbid flood of two large rivers and the small size of the gate which admits the clear waters of the ocean. A short and somewhat superficial examination of the resources of the bay lead me to a somewhat similar conclusion, yet I find the entrance to the bay one of the best places for floating animal life. From the wharf several very interesting floating animals were taken, and there is evidence that the marine zoölogist will find plenty to occupy his attention within a short distance from the city. A great advantage of San Francisco as the site for zodlogical work is the vicinity to scientific libraries and the number of fishermen a fishing boats which the city has. Climatic conditions on the coast of California render certain times of the year most advantageous for work with dredge and net. In most parts the morning is the best time for surface collecting. A *Camelo Bay is believed to be one of the most advantageous places for pra sires of marine zodlogy between Point Conception and San Fran- 42 Sea-side Study on the Coast of California. stiff breeze ordinarily arises in the afternoon and renders the collec- tion of surface life almost impossible. Surface collecting by night, so profitably carried on at Newport, met with considerable success on the coast of California. The fogs which in some months hang for many hours above the water is detrimental to this kind of work, Calms, while of great advantage to the student of surface collec- tions, try the patience of the naturalist engaged in dredging who has no steam launch at his control. The best time to dredge ! with a sailing craft was found to be about noontime, as there is less liability to be becalmed at that time, and it is too early for the heavy winds of the afternoon. In my trip across the Santa Barbara Channel, the Miiller’s net was used at intervals to get some idea of the general facies of the surface life from this region of the Pacific. The contents of the net was made up of representatives of all the more important surface animals from the Narragansett Bay. These animals are of course represented by different genera and species from those found in New England waters, but the general character of the surface life is much the same. As compared with the same latitudes on the Atlantic, it did not seem as rich,” The phosphorescence which is a direct index of the amount of surface life in the sea is often very brilliant on the Pacific coast. I have studied this light at various points on the Mediterranean, along the Florida Keys, on the coast of New England and at the Bermudas but have never seen it more striking than in the surface waters of the Santa Barbara Channel and in the fiords of the island of Santa Cruz. Ina canon fiord under Punta del Diablo, at about 9 o’clock in the evening, I witnessed a phosphorescent display of this kind of most extraordinary character. Aside from its natural beauty it was in- dicative of an abundant harvest with the Miiller’s net. The signs did not fail, although the light, as so often happens in surface col- lecting, was mainly due to multitudes of one genus of animals. At this time it was due to large numbers of a species of Copepod which is often very abundant in the Santa Barbara Channel. I have noticed in studies of live animals carried on at the Bermu- das, at Tortugas and on the coast of New England, that in the 1 I refer to shallow-water dredging and to dredging with the sailing crafts which a visitor to the coast is obliged to use. 2 The author has in preparation a paper in which the new genera and 1o ot invertebrated animals found on the coast of California in sur- face water dredging will be described and figured. 2 * Sea-side Study on the Coast of California. 43 former localities marine animals in aquaria are very tenacious of life. I believe this is in part due to the fact that there is a more uniform temperature in the winter at Tortugas, or that the changes are not as sudden in one place as in the other. At Newport, for instance, the temperature of the water varies very greatly day by day, and pelgic animals are very sensitive to this change. Pelagicanimals at Santa Barbara live longer without change of water than those on the coast of New England, and the conditions of temperature seem more like those of Bermuda than of the coast of New England. I was much surprised at the great range of temperature which the common Actinian of Californiacan bear without harm. Water which is almost lukewarm does not kill it. In pools left by the tide well- expanded specimens live for hours in water exposed to the rays of the sun. By the peculiar habit which they have of covering them- selves with sand they are able to live out of the water in the warm air for several hours. I can think of few more difficult tasks than to determine the best locality in New England to place a zodlogical station. Any com- mittee which has such a task, especially if a majority of its members are those who have never done any marine zodlogical work at any place, has my hearty sympathy. There may be places better adapted for this or that kind of work, better suited for the sise of the endowment or more convenient of access, but it is a hard task to declare which is the best place for a station. One is tempted to say that there is no place which is bad if the naturalist means to do work rather than discourse on how to do it. On the Pacific coast the problem is the same as on the Atlantic. One cannot say that this or that point is the best place to work until he or others have tried all. Honest work at almost any place on the Pacific as on the Atlantic marine zodlogy will bear good fruit. The time has come when a permanent, well-endowed zodlogical station is needed for the study of marine animals of the coast of California. An abundant harvest in all branches of zodlogical study awaits those whose good fortune it may be to originate and carry on such a station. While it is not intended in this article to belittle the contribution to our knowledge of the animals of the coast which have already been made, it is believed that the work already begun is but a small part of what will result if a permanent station, directed by those 44 Editors’ Table. who have been drilled in methods of study in marine laboratories in Europe and America, is established." The author has been told that a movement is now on foot to found a marine zodlogical station in California. It is hoped that the information is correct. It is believed that if such a laboratory is properly conducted it will lead to most important results in the advancement of science. EDITORS’ TABLE. EDITORS: E. D. COPE AND J. S. KINGSLEY. THE satire which has been everywhere for a half century leveled at the classical names of towns in New York State, given by some - schoolmaster who was in a position to give them, should have taught American nomenclators of later date a lesson. Perhaps the refer- ence to the classical dictionary has been less frequent since that time, but the poverty of imagination of the modern American has been none the less apparent. It is pardonable in immigrants to name a locality in America after their birthplace in some European country ; but when the “stock American” must search European and classical geographies for names, he advertises two things : first, his want of esthetic capacity ; second, if perchance he select some euphonious name from the Greek, his want of national spirit and character—in form at least. What can be more incongruous than the naming of one of the canyons of Colorado the Canyon of Lodore! But what especially moves us to make these remarks is the fact that we are threatened, according to the daily press, with a still more objectionable piece of Jenkinsism. The plain adjacent to the Salt River of Arizona, where so many important archeological 1 It would be a most interesting part of my article, if space permitted, to record the many valuable papers which have already been published on Californian Marine Invertebrated Animals.

Can no names be selected from the noble vocabulary of the Pueblos, or from the Spanish-American historian of three centuries ago, that we must once more throw away our character in this way. Let us see. The name of the Great Colorado River, into which the Salt River ultimately finds its way, was the Tison—a dignified name, capable of almost any application. The region of the Moquis was Tesayan. The region of the Puerco River of the East was Tiguex—a word of entirely classical form. The Rio Grande was the Cicuyé. Towns of the region were Acuco, Tutahuaco, Chia (modern Cia), (north of which was the Province of Quirix), and Braba, at the head of the Jemez River. All of these are available names, of euphonious and even classical form, appropriate to the country, and not copied from any other region. We commend them respectfully to the gentlemen in charge of the Hemenway Expedition. Cannot something be done to change the north, south, east and west places that we have in such numbers, and to prevent the crea- tion of any new ones? Why shall we disfigure our map with a North Dakota, for instance? Call it Mandania, or some other original name. The Canadians have preémpted Assiniboia—so we cannot use that. Let us have Tacoma for Washington Territory, as has been long proposed. When Montana is divided, name one of its parts Absaroka, after the Crow Indians—the best specimens of the aboriginal American on the continent. We recall two instances of changes of name in the East, with which we emphasize our remarks. New Jersey once had a flourish- ing town of Longacoming. The name was one of the few instances of successful composition of English words to be found in America. It was changed by some person of perverted sensibilities to Berlin, and is now so called! In eastern North Carolina is a pretty village once called by the euphonious Indian name of Nahunta. When we last visited the place it was called Frémont, spelled with an “6.” Comment is unnecessary. s 46 Recent Literature. RECENT LITERATURE. Gray’s “ ELEMENTS oF Botany.” !—This is a thorough revis- ion of the deservedly well-known Lessons in which, for almost a generation, American botanists have made their first acquaintance with elementary botany. In the revision the venerable author reverted to the title of his first book, which appeared fifty-one years ago! Naturally, this coincidence of names suggests a comparison of the two books. The first Elements was a duodecimo of four hundred and twenty- six pages, and was brought out by the house of G. & C. Carvill & Co., of New York, in 1836, the preface bearing date of April of that year. There is a good deal of similarity between this pioneer and the book which now, after the lapse of half a century, bears its name; and still there are very many differences. In the early book the word protoplasm did not occur, for the very good reason that Mohl had not yet coined it; nor is there any direct reference to the thing, while in the present work protoplasm, cells, cell-contents and cell-walls, receive sufficient attention to give the beginner a general knowledge of what they are. Vegetable physiology was very crudely treated in the earlier book, the extensibility, elasticity, hygroscopicity, endosmosis and excitability of plant tissues being gravely discussed in a way in striking contrast with the admirable summary given in Section XVI. of the later work. In the first Elements “spongioles”’ were still supposed to be the organs of absorption in roots, and there was supposed to be a distinct ascending and descending sap in the stem. The turpen- tine of the Conifers and the latex of various plants were considered to be special kinds of descending sap. The movements of plants were discussed as among the curious things, but the meaning or pur- pose of the movements was not suspected. In describing Dionea muscipula, it Was said of the unfortunate insect that its “ only chance of escape consists of remaining perfectly quiet until the leaf un- closes”! Pollination was, of course, treated in the old way: the Barbary stamens were said to “ seldom fail to project a quantity of pollen upon thestigma,” and it was stated that “ the relative position of the anthers and stigmas is generally such as to favor mechanically the application of the pollen to the latter.” Turning to the new book, one sees what a great advance has been made in this field—which we may call Darwinian botany— in which such terms as close fertilization, cross-fertilization, cleis- 1 The Elements of Botany, for Beginners and for Scholars.

Not less striking is the contrast between the new and the old in the chapters which treat of the flowerless plants. Half a century ago the spores of the Equisetaceze were still doubtfully discussed: the sporangia of ferns were supposed to be transformed leaves, and the search for their stamens and pistils had scarcely been given up. In these and the mosses—in fact, through- out the whole of the Cryptogams—there was no hint, as yet, of sexual organs. Compare these crude paragraphs with the concise and lucid exposition given in the new Elements, where the same groups of Cryptogams are discussed--but how differently! Pteri- dophytes and Bryophytes are given modern characters and a modern treatment. Thallphytes are briefly treated under Algæ, Lichens and Fungi, although with the statement that “of late it has been made most probable that a lichen consists of an alga and a fungus eonjoined ;” and, further, that “ botanists are in the way of bringing out new classifications of the Thallophytes, as they come to understand their structure and relations better.” When the earlier book was written Linnæus had been dead but sixty years, and his system had still so strong a hold that eighteen pages were given to an exposition of it and a discussion of the question of supplanting it with something better; and the Natural System stood so much in need of argument that forty-four pages were given to it. In the new book a short paragraph is all that remains of the discussion of the Linnean System, and less than two pages suffice for the Natural System. It need only be said that not only do these contrasts show us what advances have been made in botany in half a century, but a comparison of these two books shows, still more, the remarkable growth and perennial youth of the master-mind who wrote them. It is not given to many men to live to see such great changes in the aspect of a science as has been the good fortune of Dr. Gray, and still fewer have had the strength or ability to adapt themselves to the new views and theories. The new book has so much to commend in it that we are loath to lay it down. We particularly like these sentences in the preface : “ No effort should be made to commit technical terms to memory. Any term used in describing a plant or explaining its structure can be looked up when it is wanted, and that should suffice.” And this one, on page 156: ‘ Even the beginner in botany should have some idea of what Cryptogamous plants are, and what are the obvious distinctions of the principal families.” We like the adoption of the spelling, Phanerogam, and the names Pteridophyta and Bryophyta, and the abandonment of the “superfluous” terms frond and stipe and replacing them with leaf and petiole, in describing the structure o ferne:—Charles E.

Karpinskir’s “ UBERSICHT DER PHYSIKE-GEOGRAPHISCHEN VERHÄLTNISSE DES EUROPÄISCHEN RussLanps.'—This brochure, with its series of small maps, is a valuable addition to our know- ledge of Russian geology. At the outset the author states the curious fact, that even the oldest sedimentary rocks of Russia have not been altered, clay and sand being recognizable even in Cambrian strata, and a layer beneath the sediments of the coal formation being in some places recognizable physically and chemically as turf. Crystalline gneiss comes to the surface in Finland, Olonetz and Archangel, also in Volhynia, Podolia, Cherson, ete., in the south of Russia. Crystalline rocks are met with at a depth of 100 Russian fathoms below St. Petersburg, and at 300 to 500 fathoms below oscow. The oldest sedimentary strata (Cambrian) are the plastic clays of the St. Petersburg and Esthonian governments. Upper Silurian sediments occur in localities distant from each other, in the govern- „ments just named, in the south of Poland, and in three points on the eastern limits of European Russia. There can be little doubt that the Cambro-Silurian sea extended across the centre of Russia, from the Baltic to the Ural. In Upper Silurian times this sea had become much smaller, and was for the most part limited to the west near the Baltic, with an outline in Podolia and northern Bessarabia. Upper Silurian beds also reappear in the north. Thus at the com- mencement of the Devonian probably almost all European Russia was dry land, though sea spread from the Urals far over Asia. The fauna of this eastern Lower Silurian sea strikingly resembles that of the basin of the same age in Western Europe, though separated from it by 200,000 square versts of Middle and Upper Devonian strata. This later Devonian sea extended from the Arctic Ocean to the Caspian region. Only about 150 species of inverte- brates are as yet known from the Devonian of Russia, whilst almost three times this number occur in Belgium. During the Carbonif- erous period the greater part of Russia was covered by the ocean, though the coast had advanced eastward since the Upper Devonian. beg on sea spread westwards over Asia to the Irtish an tal. 1 Ubersicht der Bp deni as ng ep Verhältnisse Europäischen Russland wahrend der verflossen an geologischen Perioden.

This change, commenced in the Permian, ended by converting into dry land all European Russia except the south- west part of ‘Poland. Duri ing the Middle Trias, Upper Trias, and Lower Jurassic, the land surface of Russia was much as now, except that marine beds occur in southern Poland, and Liassic beds in the Crimea and Caucasus. In Upper Jurassic times the sea again spread over a large part of Russia, probably commencing in the west, as is evideneed by typical Middle Jurassic strata in that quarter. The similarity of the fossil forms of this wide-spread sea, which stretched from the Arctic to the Caspian, and covered most of the Caucasus, to those of Western Europe indicates free communication. At the end of the Jurassic period the area of this sea became much narrowed by the advance eastward of its eastern coast line, yet still communicated with the Jurassic waters of West- ern Europe until the Upper Volga stage. During the Lower Cretaceous only a narrow belt of sea divided the land of Europe dary of this sea advanced southwards. In Miocene times the regions around the Caspian and Black Seas formed part of the Mediterranean and Sarmatian basins, the latter extending eastward to or beyond the present Aral Sea. src i in Post-Pliocene times, the Aralo-Caspian basin covered a large area northward of the Caspian, while the ice of the Glacial Period swept downward from the north over by far the greater part cf European Russia, almost reaching the Aisle en basin.

On THE THEORY OF GLACIAL Morton.'—As glaciers deport themselves like rivers, in that they are constantly flowing, with greater velocity at centre than at margins, above than below, form pools and rapids, and conform themselves to channels, Prof. Forbes was led to propose the theory that: “ A glacier is an imperfect fluid or viscous body which is urged down slopes of a certain in- clination by mutual pressure of its parts.” ? He explained the veined structure of glaciers as being due to differential movement of its parts. Against this view, it was urged that ice is a brittle solid, which in the laboratory cannot be moulded as a semi-fluid, or even in na- ture, when in passing over a change of declivity of even 44 degrees, it becomes ruptured. Consequently, Prof. Tyndall applied Fara- day’s “ Law of Regelation,” è that ice when broken and moistened, re-united and could be moulded into any form by repeated crushing and pressure, and proposed the “ Fracture and Regelation theory.” He explained the veined structure of glaciers as being analogous to the slaty cleavage of certain rocks—the result of transverse pres- re Canon Moseley‘ calculated that the resistance of ice to descent is thirty-four times gravitation, and, therefore, fracture and gravitation could not be maintained. He likened the motion to the creeping of a leaden roof, owing to the expansion and contraction from change of temperature, which expansion Dr. Croll’ modified in assuming the transmission of heat from molecule to molecule with successive liquefaction and solidification of the glacial waters. Malleability, plasticity and viscosity are different degrees of the Same property. Prof. Heim® distinguishes between these last two semi-fluid forms. In plastic bodies, the internal cohesion is less than Internal resistance, and, therefore, under pressure these will flow, ut under tension they are not drawn out, but are brittle. In vis- cous bodies, the internal cohesion is greater than internal resistance, and, therefore, they will not only flow under pressure, but in ten- Sion they are drawn out before rupture. He concludes that glaciers are plastic bodies, and explains the veined structure as being due to partial liquefaction under compression in passing through narrow By Hoed before the Royal Society of Canada May, 1887, and before the ~ A.

He attributes the motion to plastic flow under gravity, rupture, partial regelation, and a sliding motion (which is slight). From observations in the Alps, and especially in Norway, my conclusions are that the motion, in the main, is the result of gravity on a semi-fluid body, wherein there is viscosity as well as plasticity, as defined by Prof. Heim; the motion, of course, being greatly modified by heat. My conclusions are based upon :—(1) The flow of the glacier, not merely in conformity to the channel, but about loose stones, which cause the lower surfaces of the glacier to be grooved (see fig. 1, in my Glacier Erosion in Norway’) without any lateral ridges being produced from the ice that filled what are now its channels, such being moulded into the mass (this is plasticity). (2) A tongue of ice (see fig. 3) pushing against a boulder, was bent back without rupture on either side of the hanging plate,—the ice on one side being in tension and on the other in compression (here is viscosity). (3) A large rounded boulder (see fig. 2), held in the side of a moving glacier, where the rounded ice wall rose about thirty feet above the stone, which was being rolled along as the ice moulded around it, had just been crushed by weight. The glacier rore along its winding course to the snow fields, 1,500 to 2,000 feet above the stone. Consequently the crushing weight upon the gran- itoid boulder must have been derived from the vertical component of the momentum of descent of the whole mass, which could be transmitted thus only through a semi-fluid body. (4) The flow of the upper layers of ice over the lower was seen when the glacier was impeded by a barrier (see fig. 4). The experiments of Herr Plaff? show that a solid body can be pressed into ice at a temperature about freezing point as rapidly as glaciers ordinarily move ; whilst at a temperature a little above, the motion is greatly accelerated, but if below 0° ©, the plasticity of the ice diminishes rapidly to almost zero. However, as shown by the sub-glacial streams in winter, the temperature of the inferior sur- face glacier is not below freezing point. The effects of increased summer sunlight, as well as direct heat, as shown by the experiments of Rev. A. Irving, in which he trans- mitted both sunlight and heat waves through ice, is to accelerate the movement as the former is converted into heat undulations, and radiated against the lower part of the glacier from the adjacent rocks, thus increasing the fluidity of the ice and flow of the glacier, owing to increase of temperature. The temperature of the lower surface of the glacier is also slight- ly increased by the radiation of the internal heat of the earth, yet 1 See American Naturalist, March, 1888. S 2 Nature, Aug. 19th, 1875. 3 Q. J. @. S., Feb., 1883 Geology and Paleontology. 55° this is very slight, as the amount radiated per annum is only enough to melt 6.5 millimetres of ice.! Although glaciers do not conform to all the inequalities of their’ beds, and at the ice-falls and elsewhere became fractured, and sub- sequently re-united, whether by heat regulation or plastic flow, the fluidity theory is the most acceptable explanation of the motion of glaciers, even when the angle of descent is reduced to almost zero, : and modern observations only supplement the reasons upon which - Prof. Forbes proposed his theory more than forty years ago.—Prof. J. W. Spencer. A Cretaceous Brrp-Track.—Professor F. H. Snow has re- cently, in the Trans. Kansas Acad. Sciences, described a fossil bird-track discovered in the Dakota sandstone, in Ellsworth county, Kansas. The impression appears to have been made by the left foot of some bird with an elevated hind-toe just reaching the ground. The ball of the foot is deeply impressed and the posterior toe has made an unmistakable imprint, proving the avian character of the’ footprint. It measures two inches from anterior middle claw to claw of posterior toe. This discovery considerably lowers the geo- logical horizon of Kansas birds, since nearly all the material for Marsh’s Toothed Birds was obtained from the Niobrara, the highest group of the Cretaceous represented in Kansas. Below this lies the Benton, followed by the Dakota, resting unconformably on the Permo-Carboniferous rocks. Professor sSnow continues thus: “The wonderful luxuriance of the land vegetation of the Dakota, and its marvellous similarity to the Dicotyledonous forest-growths of the warm-temperate climes of. the present day, have rendered these sandstone beds a most fasci- nating field of investigation for both Paleo-botanists and Neo-' botanists. The finely-developed and perfectly-preserved foliage of oaks, willows, poplars, laurels, sarsaparillas, magnolias, sassafras and other kindred forms belonging to genera now long since extinct have hitherto suggested a beauty of landscape whose perfection was only marred by the apparent scarcity of animal forms. . . . . Our bird-track supplies the missing element of graceful serial forms. From the size of the footprint, it may be safely inferred that the bird which left it was somewhat larger than a pigeon. It was prob- : ly a bird with teeth,” “with habits similar to those of the modern ern. ; _ THE AFFINITIES oF Mroianta,—G. A. Boulenger reports (P Z. Soc. Lond., June 23, 1887) that the ‘large Plistocene Chelonian Miolania, which was regarded by Huxley as probably belonging to the group Cryptodira, and closely allied to Chelydra, Macroclem- mys and Platysternum, is, in fact, like all the recent tortoises of f ' Elie de Beaumont, Thompson Woodward and others, give range © rom five to eight millimetres. University of Missouri, May Ist, 1887. 56 General Notes. Australia, a member of the Pleurodira. Mr. Boulenger bases his opinion upon the examination of a nearly perfect skull with the two cervical vertebree attached. The structure of the alveolar surface of the skull indicates an herbivorous animal ; the ungual phalanges and the curious sheathed tail a terrestrial one. This sheathed tail, with its opisthoccelous centra, is unique among the Pleurodira, and points toa distinct family. The ilium shows a surface for attachment to a sacral. The Pleurodiran characters are—the broad pterygoids, with outer palatal borders forming wing-like expansions ; the tympanic cavity completely surrounded by the bony roof; the articulation of the mandible by a condyle fitting into an articular concavity of the quadrate, and the form of the cervical vertebree. GEOLOGY OF THE SoLomon IsLanps.—Mr. H. B. Guppy has recently published a work upon the Solomon Islands, divided equally tween the volcanic and calcareous members of the group. The volcanic islands fall into two classes—the first comparatively modern and mainly composed of little-altered augite sandstones, andesitic pitchstones, tuffe and agglomerates; the second, composed partly of the above rocks, but in part of much more ancient crystalline masses, consisting chiefly of altered dolerites, quartz-diorites and porphyies and serpentines. 7 he coral rocks of the Solomon Islands are divided by Mr. Guppy into: (1) True coral limestones; (2) Coral limestones which have the composition of the coral muds or sands now forming near coral reefs; (3) Rocks having the composition of volcanic mud and pteropod ooze ; (4) Foraminiferal limestones; (5) Rock resembling a consolidated deep-sea clay (red clay). The two last classes were evidently deposited at depths of not much less than two thousand fathoms in an ocean far from continental land ; and this is the first proof of their existence above sea-level. Mr. Guppy draws the following inferences: (1) That these up- raised reef-masses, whether atoll, barrier reef or fringing reef, were formed in a region of elevation ; (2) That such upraised reefs are of moderate thickness, their vertical measurement not exceeding the usual limit of the reef-coral zone; (3) That these upraised reef- masses, in the majority of islands, rest on a partially consolidated deposit which possesses the characters of the “ volcanic muds” that were found, during the Challenger Expedition, to be at present forming around volcanic islands; (4) That this deposit envelopes anciently-submerged volcanic peats. The author says: “ I never found one (raised reef) that exhibited a greater thickness of coral limestone than one hundred and fifty feet, or, at the outside, two hundred feet.” GEOLOGICAL SURVEY OF ARKANSAS.—From a small pamphlet —Annual Report of the State Geologist of Arkansas for 1887— Geology and Paleontology. 57 we learn the Survey began work June 24th, with a corps of a director, three paid and seven volunteer assistants. The work done the first year has been the triangulation of the immediate vicinity of Little Rock ; the examination of localities reported to yield gold and silver, especially in Garland and Montgomery counties; a reconnoissance in the central part of the State; tracing the limits of the Cretaceous in the southwestern part of the State. The bill providing for the survey makes appropriations for its continuance for two years. GrEoLocicaL News.—Patmozoic.—Dr. J. V. Deichmiiller describes two new species of the genus Etoblattina Scudder obtained at Griigelborg, near St. Wendel (Rhenish Prussia), not far from a spot where fish, insect and plant remains have been previously ee They are described under the titles of E. ornatissima and . rollei. CRETACEOUS.—Mr. A. S. Woodward concludes, after examination of the five series of examples in the British Museum, that Cyclobatis oligodactylus, the so-called “ Torpedo,’ from the Cretaceous of Mount Lebanon (Syria), is really a member of the sting-ray family (Trygonidz). Among his reasons are: The pectoral fins are unin- terruptedly continued to the end of the snout, and were thus, prob- ably, confluent in front—a condition never met with among the Torpedinide ; the pelvic arch is placed far forward; there are no traces of median fins, and the skin is armed with spinous tubercles. From an examination of specimens in the Cambridge and Brighton Museums (Eng.), Mr. A. S. Woodward concludes that the puzzling genus Ptychodus, which was by Agassiz and Owen referred to the Cestraciontid, is doubtless a true ray, though possibly belonging to an extinct family. Mr. J. W. Davis (Trans. Roy. Dublin Soc., 1887) describes the fossil fishes of the chalk of Mount Lebanon. In this important eels yet known,—are among the Teleosteans. 58 General Notes. GEOGRAPHY AND TRAVEL. ! AFricA.—THE EASTERN DESERT oF Eaypt.—‘NotesonaSketch | Map of Two Routes in the Eastern Desert of Egypt” is an inter- vesting account of the scenery, ete., of a little-known part of Egypt proper, viz., the stony desert lying between the Nile valley and the Red Sea. The desert rises from the Nile for about a hundred miles, where the elevation is 2,000 feet, and thence shelves more sharply , to the Red Sea. The Red Sea slopes are blessed with frequent rain- storms; waterfalls, crystal pools, fern-clad grottoes, even trees, can be found in the wadis or valleys which seam their sides, and even the Nile slope has its picturesque ravines and tree-sprinkled nullahs. The inhabitants of the district are the Ma’aze tribe of Bedawin, who live in goats’-hair tents, to the north ; and the more civilized Ababdi to the south. This Eastern Egyptian desert was probably the scene of the first monasteries in the world. Those of | St. Anthony and St. Paul, about nine miles apart, and situated about seventeen miles from the coast, in latitude 29°, are still visited by travelers. Almost the entire traffic between Rome and India passed, two thousand years ago, along the old trade route between Kosseir, on the Red Sea, and Koptos (modern Kuft), on the Nile. Every five’ or six miles along the route a more or less ruined khan exists. — In the Messiigh El Bagar are quarries, once worked by the ancient Egyptians, and bearing inscriptions by the Persian conquerors. Roman stations exist, one of them is Saghi or Naka’al Teir. Ibex: are abundant, choosing for their home the wildest and most inacces- sible mountains. THe Ratan Moeris.—Mr. Cope Whitehouse sees in the Raian basin the Lake Meeris of ancient geographers, and states that sur- veys carried out under his direction by the authorization of the Egyptian government, prove that the area can again be converted into a storage reservoir for the surplus waters of the Nile. The number of reclaimable acres in Lower Egypt is given at about five millions ; and the surface of the Wadi Raian, at 20 metres above the Mediterranean, at 346,000,000 metres, with 25,540,000 metres of contents. Colonel Ardah states that there are no engineering difficulties in the way of utilising this large basin. PHYSICAL GEOGRAPHY OF FERNANDO PO.—Petermann’s Mit- teilungen contains an account of the physical geography of Fernando _ Po, by Oscar Baumann, a member of Dr. Lenz’sexpedition.

The volcanic peak’ O-Wassa or Clarence Peak, 10,030 feet in height, almost entirely covers the northern half of the island. West and northwest this mountain is cut by deeply eroded gorges ending in a narrow belt of flat country; to the north and northeast the sides slope gently to a precipitous rocky coast; on the east the pre- cipitous slopes end in a grassy plateau about 1,300 feet above the ocean, while on the southwest there is a gradual descent to the pla- teau of Batec, which connects O-Wassa with the southern moun- tain system. The crater is 575 feet deep. The southern moun- tains for the most part present an almost perpendicular front to the sea. They form two chains and are basaltic. A volcanic mass south of these ranges has what appear to be remains of craters. The principal river is the Uaya or Shark. Few of the rivers rise at a height of more than 2,000 feet. THE Cavcasus.—Though Elbruz is still the monarch of the Cau- causus, several peaks are now known to exceed 16,000 feet. Among these are Tetnuld (16,700 feet), recently ascended by Mr. Douglas Freshfield ; a peak climbed in 1886 by Mr. Dent and Mr. Donkin (16,550 feet by their estimation); Schkara and Djanga, which Mr. F reshfield estimates respectively at 17,200 and 16,900 feet, and the Koshtantau, 17,096, and Dychtau, 16,925 feet, of the Russian maps. Mr. Freshfield states that travel in this region of grand mountain scenery is now quite safe. ASCENT OF THE OWEN STANLEY RANGE.—Messrs. C. H. Hart- mann and G. Hunter have succeeded in reaching the summit of the Owen Stanley, the principal range of mountains in British New Guinea. Twenty-seven friendly natives accompanied them in the ascent. Some difficulty, which was peaceably overcome, was en- countered with a tribe which guardsthe great mountain Paramagoro, believed to be the abode of the spirits of the departed. It rained nearly all the time the party were on the mountains. The flora was magnificent in the extreme. It does not appear that the highest Summits were reached. 60 ` General Notes. DISCOVERIES IN NEW GUINEA.—T wo new rivers, named by their discoverers the Jubilee and the Douglas, have been found and mapped by the exploring party sent out on the Victory by Messrs. Burns, Philp & Co. Very few natives were met with, except upon the sea-coast, and these were not particularly hostile. The Douglas was followed to Bowden junction, from whence the eastern tribu- tary (Philp River) was taken until a point was reached about 100 miles up the stream and 25 from the German boundary. The Aird River was found to be but one of the mouths of the Douglas. The Jubilee River opens into Deception Bay, at the head of the Gulf of Papua, about half a degree west of the mouth of the Douglas, and trends northwestward toward the Albert Victor Range. It, also, was followed for about 100 miles. The entire coast region here is very swampy, with dense undergrowth, but the interior is a hilly wooded country. Cretaceous limestone was met with on the Philp River, while basaltic rocks occurred still higher up, and were also met with upon the Jubilee. Both rivers have several mouths, their deltas covering about 40 miles respectively. The natives gave indications of Dravidian origin. Their canoes were dug-outs with outriggers, and often large. They wore nose-pencils, and distended the lobes of the ears. f | ; l j GEOGRAPHICAL News.—Dr. A. Meyer, of Leipzig, who has recently succeeded in ascending Kilimanjaro to the glacier-walled crater-summit of Kibo, and has explored the volcanic plateau which lies between Kibo and Kimawenzi, estimates the altitude of the — former at 19,680 feet, instead of 18,800, as believed by Johnston, who reached 16,000 feet. M. Sibiriakoff has again despatched the steamer Nordenskiold to the Yenisei via the Kara Sea. The vessel left Norway in August, — and reached the mouth of the Petchora, where she received a cargo of skins, corn, tallow, and mammoth tusks. The Phoenix of Leith succeeded in entering the Yenisei itself. From accounts received from various parts of the Arctic Seas of the state of the weather and the ice during the past summer it appears that the steady and continuous prevalence of easterly — and northeasterly winds forced the ice from the regions north oF — Spitzbergen and Nova Zembla down into the seas around North- a ern Norway, Jan Mayen, Iceland, the Faroé Islands, and the T east coast of Grenli This is thought to account for the early — setting in of winter experienced in England. Dr. H. V. Jhering has ee up the Cainacuam, a river 12 — the Brazilian province of Rio Grande do Sul, from its delta t0 the town of S. Jose. Throughout its lower course the river win% in sharp curves, and while the right bank is steep and woode@, — the left is flat and covered with gravel.

Dr. Jhering’s map (Petermann’s Mit- teilungen) shows that the Cainacuam has five mouths, while that of the government engineer (1882) shows but three. Many valu- able woods occur in the forests. The “campos,” or open tracts, which are invariably higher than the forest-covered country, are referred by Dr. Jhering to the diluvial period, while the wooded lands are alluvial. M. von Fetvelde, in a “Notice” upon the Congo Free State, gives its area at 1,075,000 square miles. MINERALOGY AND PETROGRAPHY:.' PETROGRAPHICAL NEws.—The volcanic bombs from the Lake Laach district are divided by Hubbard? into four classes—old crystalline and schistose bombs, sanidinite bombs, trachyte bombs, and basalt bombs. The last three varieties are difficult to separate from each other, but are easily distinguishable from the first class. After discussing very briefly the various theories proposed to account for these bodies, the author proceeds to investigate those in which nosean occurs. He examines two hundred and sixty thin sections of nosean-bearing bombs, and reaches the following conclusions : (1.) The Nosean is in greater part a druse mineral. (2.) The inclus- sion so characteristic of this mineral consist of magnetite, either fresh or slightly altered. (3.) The little red octahedra so frequently accom- panying the titanite of the Lake Laach bombs is closely related to the pyrrhite of San Miguel, and has probably been derived by the alteration of titanite. Several other points of interest in relation to the minerals occurring in these bombs are noted. The most impor- tant results reached, however, are those which have been mentioned. —The elzeolite-syenite from the vicinity of Rio de Janeiro, Brazil, has recently been carefully examined by Fr. Graeff? The mass o the rock is described as possessing a holocrystalline hypidiomor- phic structure. Its principal constituents are hornblende, ortho- clase, eleeolite, augite, and mica. The feldspar is noticeable for the possession of a parting‘ parallel to 7 Pæ. In other cases it is intergrown with very fine lamellz of plagioclase, thus showing stri- ations when examined under the microscope in polarized light. The elæolite is generally fresh, but in some instances is altered into sodalite and analcite. The accessory minerals are titanite, apatite, zircon, fluorite and a black garnet. The rock is interesting, as affording another example of the predominance of hornblende p edited by Dr. W. S. Bayley, Madison, Wisconsin. k pieh u. Petrog. Mitth., viii., 1887, p. 356. i s Jahrb. f.

In it are many little veins of a finer-grained elmolite-syenite, which show very clearly the effects of pressure, and which are remarkable for the number of accessory minerals they contain. A second variety of the rock, found as blocks in the Rio de Ouro, consists of elxolite, orthoclase, egirine and mica, together with a large number of accessory constituents. Among the latter are rinkite and lavenite. The former’ occurs in long narrow plates, marked by cleavage lines parallel to their longer axes, The min- eral is slightly pleochroic in yellow tints. The plane of its optical axes is perpendicular to the cleavage. It is readily attacked by concentrated hydrochloric acid, with the separation of gelatinous silica, The lavenite? occurs in highly refractive, strongly pleochroic, honey-yellow crystals, and is closely associated with the magnesium- iron constituents. A third variety of the Eleolite-syenite is porphy- ritically developed. It occurs in the form of a dyke in the holoerys- talline rock described above, and contains inclusions of a finer-grained rock: of the same general nature-—The massive rocks of the Lead- ville Region, according to Mr. W. Cross,? comprise quartz porphy- ries, rhyolites, audesites, porphyrites and diorites. e porphyries are the most interesting, in consequence of their relation to the ore bodies. They are divided by Mr. Cross into several varieties, each of which is carefully described. That phase known as the Lincoln rphyry is noteworthy, as containing the rare accessory allanite.' he sanidines of some of the rhyolites possess a peculiar satiny lus- tre, due to fine partings parallel to 42 Pz. The cavities of these rocks are covered with little crystals of sanidine, quartz, biotite and topaz. In the porphyrites biotite is frequently found in tiny green flakes, with a very strong pleochroism, and rounded grains of quartz are sometimes surrounded by an aureole of quartz and feldspar. It is interesting to note that in certain cases epidote is the final prod- uct of alteration of all the minerals of the porphyrites, while in other cases this final product is muscovite——J. F. Williams* has recently described, in a very finely illustrated paper, the trachytes composing Monte Amiata, in Tuscany. These trachytes by altera- tion yield products which approach very closely to rhyolite on the one hand, and on the other appear very like andesites. The paper is enriched by numerous analyses of feldspar, hypersthene, and types of trachyte.-—In a late number of the Neues Jahrbuch fur Mineralogie, Reusch® illustrates, in a very beautiful manner, the effects of pressure on sedimentary and massive rocks, In the case of conglomerates, he shows how a schistose structure may be induc which is entirely distinct from the bedding due to sedimentation. 1Cf.

Its thin sections show well-crystallized chondra in addition to enstatite, olivine, troilite, iron and glass. After describing the structure of the meteorite in detail the author proceeds to discuss the various theories which have been proposed to account for the origin of these bodies. He shows the weakness of each, and immediately suggests a new one, in which meteorites are regarded as made up of little particles of cosmic substances, which together with the sun, planets, ete., compose the solar system. He shows how this sub- stance might unite and give rise to a meteorite with the brecci- ated structure so frequently noticed, and concludes by giving sey- eral reasons for the acceptance of his theory—A meteoric stone which fell at Angro des Reis, in Brazil, during 1867, contains a calcium-rich red augite as one of its constituents. It is conse- quently richer in calcium than any meteorite heretofore described. It belongs about midway between Rose’s eukrites and howardites. Ludwig and Tschermak? propose to establish a new class of mete- orites, of which this shall be the first member. They call it the augrite class.—A lithosiderite,? found last March ina field eight and a half miles west of Rockwood, Cumberland county, Tenn., con- _ sists of about 16 per cent. of metallic iron and 84 per cent. of a stony portion made up of anorthite and enstatite. The metallic grains are evenly distributed throughout the mass, and when pol- ished and etched show the usual figures. The stony part presents a brecciated appearance. Through it are scattered the metallic nodules mentioned above, and others consisting of an iron-rich enstatite. It is unfortunate that the careful analyses of the consti- tuent portions of this meteorite are unaccompanied by descriptions of its thin sections.—A meteoric stone having the composition given below is mentioned by Daubrée‘ as having fallen at Djati-Pengilon, in Java, on the 19th of March, 1884.

The high character of the illustra- tions, noticed in former reviews, is maintained, and the number o references is still further increased. The entire volume, exclusive of index, contains 1087 pages, 504 illustrations, and references to 414 topics.—Another very welcome addition to geological literature has appeared in the concluding part of the second volume of Roth’s “ Chemische Geologie.” ? This brochure embraces in its treatment the crystalline schists and the sedimentary rocks. Like the earlier ' portions of the same volume, this part is especially valuable for the copious references to articles relating to the spread and character of these important classes of rocks—classes which have hitherto been neglected by writers of handbooks of petrography. The lists of — localities in which the different members of these great classes 0 rocks are found, is very full, except in the case of North America, where it seems that many localities have been overlooked. The book, however, is one which no geologist can well afford to be without. 1 Amer. Jour. Sci., June, 1887, p. 494. 2 Amer. Jour. Sci., June, 1887, p. 500. 3 D.

BOTANY 5 SCHRŒTER’S ARRANGEMENT OF THE USTILAGINE®. — In Cohn’s Kryptogamen-Flora von Schlesien, Schræter divides the order Ustilagineæ into three families, as follows, viz. :— I. Ustilaginacei, containing the genera Ustilago Pers., Sphacelo- theca De Bary, Schizonella Schroeter, Tolyposporium Woronin. II. Tilletiacei, with the genera Tilletia Tul., Urocystis Rabenh., Entyloma De Bary, Melanotenium De Bary, Tubercinia Fr., oassansia Cornu. Ill. Thecaphorei, with the genera Schreeteria Winter, Theca- phora Fingerh., Sorosporium Rudol. The genera Graphiola Poit., Entorrhiza C. Web., Piapalopsis J.

TUMBLE-WEEDS AGAIN.—The latest addition to the lengthening list of tumble-weeds is Corispermum hyssopifolium L., which in northern Nebraska assumes the globular form now so well known as characteristic of the tumble-weeds, and late in the season gives itself to the winds. Fine specimens were brought to me in Sep- tember, 1887, by a correspondent from Long Pine, near the iobrara River. In this connection, it may be well to direct attention to the account given by R. M. Christy, in his “ Notes on the Botany of Manitoba,” which appeared in the October number of the Journal - of Botany, of the tumbling habit of Psoralea esculenta, the “ Indian of the prairies: “ After flowering, instead of withering away, the plant remains standing, and by the time its seeds are ripe it has become—flowers, stalks and all—perfectly dry, brown and rigid. In this condition it is very light. The stem then sepa- rates just below the ground, leaving the entire plant free, to be blown about by the wind over the surface of the prairie, dropping its hard, oval seeds as it goes.” Mr. Christy weighed a number of plants and found that, while they averaged six and a half inches in height and bore three flower-clusters each, they had an average weight of but a trifle over thirty grains.—Charles E. Bessey. BorantcaL WORK IN Mrynesora.—The Report on the Botan- _ ical work in Minnesota for the year 1886, which was distributed the Ist of October, 1887, gives one a very good idea of the kind of work which is being done by those constituting the working force of the Geological and Natural History Survey of the State. Pro- fessors Arthur and Bailey, with Mr. E. W. D. Holway, made an expedition to Vermilion Lake, where they remained for some time engaged in the critical study of the flora of the region, Other points were visited, and collections were made. The party was composed of experienced collectors, and the results were unusually good. Two of the party were acute students of the fungi and other — lower plants, while the third was equally well prepared for s work on Glumaces and Amentace, as well as the Phanerogams : in general. The list of specimens collected is a remarkably good one, num- 1 bering seven hundred and sixty-two in all. These are distributed as follows :— Botany. 67 Phanerogams . ; š . 368| Odphytes. i , < See Pteridophytes . ; > i 26 | Zygophytes . í ‘ . 45 Bryophytes ‘ < ‘ . 42| Protophytes . è ‘ i a8 Carpophytes . b: : . 242 The 227 Dicotyledons are represented by 90 Choripetale, 100 Gamopetale, and 37 Apetale. Of the 135 Monocotyledons, 47 are sedges, and 30 grasses. Of the Carpophytes, there are 77 Hymenomycetes, 39 Uredinex, 36 Lichens, 57 Pyrenomycetes, and 21 Helvellacee. The Zygophytes are mostly Desmids (31 species) and Diatoms (12 species), while 19 of the Protophytes are Slime Moulds. The specimens upon which the entries are made are all preserved in the Herbarium of the Survey, a precaution well worthy of general imitation.— Charles E. Bessey. BoranicaL News.—Dr. Farlow describes in the September Botanical Gazette an Æcidium on R ar, to which he gives the name of Æcidium bermudianum. Coulter and Rose continue their useful studies of the Umbelliferse in the October and Novem- ber numbers of the same journal. Dr. T. F. Allen appears again in the pages of the Torrey Bulletin for October with a paper on Characeze, accompanied by five plates. Two new Nitelle and one Tolypella are described. The November and December numbers of the Journal of Mycology are principally filled with Dr. J. W. Eckfeldt and M. W. Calkins’ Lichen Flora of Florida, being a catalogue of species, with notes, and also notices of new species. art 3 of Professor Greene’s Pittonia contains an excellent bio- graphical notice of the late Dr. Albert Kellogg, well known for many years as a collector and student of the Pacific coast plants. The editor, in an article on Echinocystis § Megarrhiza, insists strenu- ously that the older name of Mara should be used instead of Me- garrhiza, The Californian Manzanitas received the attention of Dr. C. C. Parry in a paper read before the California Academy of Sciences. They belong to the Uva-Ursi section of the genus Arc- tostaphylos, and number twelve species in all. R. P. Bigelow’s paper on the Structure of the Frond in Champia parvula, read before the American Academy of Arts and Sciences, now issued as a reprint from the “ Proceedings,” is a careful study of the struc- ture of this member of the Floridex. he Development of the Ostrich Fern (Onoclea struthiopteris), by D. H. Campbell, being the “Walker Prize Essay” for 1886, has been printed in the Memoirs of the Boston Society of Natural History. It is accom- panied by four good plates. The Bulletin of the Illinois State Laboratory of Natural. History, lately issued, contains an important contribution to our knowledge of the Erysiphee, by Professor Burrill and F. S. Earle. The Illinois species are carefully described, and the synonymy has received close attention. Several 68 General Notes. changes have been made in the names of common species. ——J Baker continues his synopsis of Tillandsiese in the November Jour- nal of Botany, reaching No. 112, with the article to be continued. In the December number of the same journal Otto Nordstedt points out that a great many of the figures in Cooke’s British Der- mids are copied from Ralfs, Archer, Brébisson, De Bary and many other authors, in spite of the statement that “the greater part of the figures have been drawn direct from the specimens them- selves.” We must suppose that the artist imposed upon the author in this case. G. Massee publishes in the December Grevillea a revision of Polysaccum, admitting eight species, of which two, P. pisocarpium and P. turgidum are American. ENTOMOLOGY. THE Hop PLANT-LOUSE, Phorodon humuli.—An important con- tribution to our knowledge of the life of this species was made during the year just closed, by the Entomologist of the U. S. Department of Agriculture. ’ Professor Riley, assisted by Mr. Per- gande, Mr. Howard, and others, very carefully traced the transfor- mations of the species throughout one complete cycle, i.e., from the winter eggs of one year to those of the year following. The most interesting result of these investigations is the confir- mation in a striking manner of the previously known fact that this species passes the winter on plum trees It is urged by Professor Riley that this is the only mode of hiber- nation of the species, or at least-that it does not winter on the hop. This is a point of the highest practical importance, and one which must be settled before a complete plan of defence from the ravages of this pest can be matured. Unfortunately, the evidence adduced by Miss Ormerod in her report for 1884, and indicating that one form of this species winters on the roots of hops, is too strong to be set aside by anything yet advanced, The following is a résumé of the transformations of this insect, as determined ie Professor Riley, and published in advance of his annual report’: “ As soon as Pian leaves put out in spring, the first generation of lice hatch from the winter eggs on plum. These are wingless agamic females, giving birth to young ike themselves without the intervention of males. The third successive generation upon plum however, is winged, not wingless, and the first fledged individuals 1 This department is edited by Prof. J. H. Comstock, Cornell Univer sity, Ithaca, N. Y., to whom communications, books for notice, etc., sho uld be sent. 2 L. O. Howard, The Cultivator and Country Gentleman, N ovember 17, 1887. ; ; Entomology. 69 of this generation the present season were observed June 4. The individuals of this winged generation migrated at once to the hops, settled and began giving birth to the fourth generation, which con- sisted, as did the second, of wingless, agamic females. The fifth, sixth, seventh, eighth, ninth, tenth and eleventh generations fol- lowed, and were all composed, as was the first, of wingless agamic females, bringing observations in point of time down to the last week in August, or close to the commencement of hop-picking. “ The last week in August the offspring of the eleventh genera- tion (themselves the twelfth) showed rudimentary wings, and at the same time the offspring born the previous week from the still living females of previous generations (as far back as the fifth) also showed plainly that they would become winged. August 26th the first winged females were observed at Cooperstown, and August 31st at Richfield Springs, the main locality for observations. Sep- tember 2d they had already flown in small numbers to both Dam- son and wild plum, and had begun to deposit larvæ, which may be called the normal thirteenth generation. From day to day the winged lice increased in numbers until on the 13th of September the air was literally full of them, flying from the hop fields and settling on every variety of plum, and upon every available plum leaf. They were found a mile distant from any hop plant, search- ing for some plum tree on which to settle and bring forth young. Standing in front of a plum tree and facing toward a neighbor- ing hop yard, Mr. Pergande observed a swarm coming from the hops and settling upon the plum. A most interesting point in this connection is the fact that none of these winged generations will settle and reproduce on hop. This was proven by careful and repeated experiment. So great were the number and so com- pletely were the plums in certain places covered, that many of these winged females were obliged to settle upon neighboring weeds, where they brought forth young, which, however, died after feed- ing a few days. “All of these winged individuals of the twelfth generation which migrated to plum up to September 28th were agamic females. (A few were still flying late in October.) Their young (thirteenth generation), however, attained full growth by this date, and proved to be all true sexual females, wingless. At this time the males were discovered. They proved to belong to the twelfth generation, but only to the very late and much retarded offspring of the retarded agamic wingless eleventh. They developed late in Sep- tember upon the fragments of hop vines still remaining in the hop fields, and became winged the last week in September, just in time to fly to the plum and mate with the wingless sexual females which became full grown at this time or a little before. Immediately after this mating the eggs n to be deposited, and by October Tth large numbers could be found without trouble on the smaller t and branches of plum, in and around the angles formed by the bnds and twigs. Each female laid from one to three eggs.” m 70 General Notes. ON THE OCCURRENCE OF APTEROUS MALES AMONG THE ÅPHI- pip#.—In view of the very few species of American Aphides in which apterous males have as yet been found, it may be of interest to call attention to the occurrence of this form in certain species whose autumn life history I have lately been studying. In Schizo- neura carnicola this is the only male form produced, and it may be found abundantly during October on the leaves and twigs of various species of Cornus, often in copulo with the oviparous females. It also occurs in the root form of the corn-plant louse (Aphis maidis), having been taken with the oviparous females during October, in ant colonies, about corn roots; and in a species of Aphis, found abundantly in certain plants of Amarantus albus, during October. In all of these species the male is of the same general form, being slender and flattened, with long legs and antenne, and very active in its movements. The only reference to the occurrence of this form in America which has come to my notice is by Professor O. W. Oestlund, in his List of the Aphidide of Minnesota,' in which he records finding it in several species of Siphonophora. I presume that when our spe- cies are more thoroughly studied it will be found to occur quite frequently. It is to be hoped that the recent progress made in our knowledge of the life-history of the group will stimulate a more thorough study of these much-neglected insects.— Clarence M. Weed, Ill, St. Laboratory of Nat. History, Champaign. THE IMPORTED CABBAGE Burrerriy.—Mr. S. H. Scudder has collected a large amount of data regarding the introduction and spread of Pieris rapæ in North America. This he has very carefully digested and published as one of the Memoirs of the Bos- ton Society of Natural History.2 This memoir is accompanied by a map showing the centres and annual areas of distribution of the RETE i North America from its introduction in the East in 1860 to . The chief points brought out by Mr. Scudder’s paper are the following :— (1.) The insect was first captured in this country in 1860, by Mr. Wm. Couper, near Quebec. “ From what we know of the rapidity with which a single pair may propagate, without hindrance from parasites, we may conclude with almost certainty that it was intro- duced in the early part of 1860, or, at the earliest, at the very close of 1859.” This is a later date than is commonly assigned. (2.) In addition to the importation by way of Quebec, the species was introduced independently in New York in 1868, at Charleston in 1873, and at Apalachicola in 1874. These later introductions may have been by means of coasting vessels, or by rail from the North. 1 Fourteenth Ann. Rept. St. Geol. of Minn., pp. 19-22. sL c, Vol. iv., No. iii. Zoology. 71 (3.) The westward spread of the species was hastened by its spread- ing from colonies established at Indianapolis in 1874, and at Chi- cago in 1875. (4.) The species has reached the natural limit to its southern extension. This is shown by the fact that it can hardly maintain itself at Apalachicola and has not pushed its way into the peninsula of Florida beyond, hardly to, Jacksonville, although it has for ten years been within what would elsewhere be not more than a year’s flight away. On THE SYSTEMATIC POSITION OF THE MaLLopHAGA.—Dr. Packard reviews! our knowledge of the structure of the Bird-lice, and compares them with the Pediculide and with the Psocide. He concludes that the Mallophaga are nearest allied to the Psocide, and are degraded members of the order to which the Psocide belong. He divides his order Platyptera into two sub-orders :— - NTOMOLOGICAL News.—Mr. S. H. Scudder published in the Canadian Entomologist for November “ Comparative Tables for the Families of Butterflies.” The characters of the families are given at great length, and include every stage of life.

Packard, with a systematic and general index, prepared by Mr. Samuel Henshaw, forms Bulletin No. 16 of the division of Entomology of the U. 8. Department of Agriculture; 339 titles are enumerated. ZOOLOGY. CONTRIBUTION TO THE FRESH-WATER Rurtzopops.—During the last season some investigation was made for Rhizopods to a this important group of animals before my pupils in ogy. Gatherings, from sphagnum swamps, the ooze of springs, ponds and sheltered coves along the Penobscot River near Orono, were examined, By consulting Dr. Leidy’s Rhizopods of North America the following species were determined. 1 American Philosophical Society, September 2, 1887. 72 General Notes. The majority of the species enumerated occur in a sphagnum swamp on the College farm. The list represents the observations of a single season, and will, of course, be extended by closer research, i References to figures and plates refer to Dr. Leidy’s Rhizopods of North America.

Worms 1n Hen’s-Ecaes.—Dr. Edward Linton records ( Proceed- ings U.S. National Mus., 1887) the occurrence of Distomum ovatum in the white of a hen’s-egg from Berlin, Wise. ‘The occurrence of this parasite in the eggs of fowls, while not common, is not difficult to account for. Its favorite place of lodgment in its host is in the bursa of Fabricius. An individual may occasionally penetrate one of the passages which communicate with the cloaca. It is well known that such excursions are sometimes made by this parasite into the oviduct. If it should penetrate beyond the shell- forming glands when an ovum is in transitu, it would not be an improbable thing if the parasite should find itself enveloped in the glairy albumen which is being exuded there.” In this connection we may refer those interested to a recent arti- cle on two cases of enclosure of nematodes in hen’s-eggs which are discussed in Dr. Pelletan’s Journal de Micographie, xi. pp. 407 et 512, 1887. Tue RELATIONS OF THE EUROPEAN AND AMERICAN HELICI- p#£.—Dr. Wilhelm Kobelt, at the Wiesbaden meeting uf the Con- gress of German Naturalists, compared the recent and fossil European Helices with those of America. He showed that while to-day the molluscs of Europe differed greatly from that of Central America, the miocene forms of the former country so resembl those of the Antilles and of North America that the latter might be regarded as descended from the former. He is even inclined to believe in such a genetic connection, which, contrary to that of mammals and plants, has gone from east to west, and claims that @ land-bridge between the two continents must have been north of the Sahara, because of the absence of African types in America. Zoology. 75 EXCRETORY ORGANS OF SpIDERS.—Some recent investigations of Dr. J. C. C. Loman ( Tijdsk. Nederl. Dierkunde Vereen i. p. 109. 1886-7) on the so-called Malpighian tubes of spiders are of interest. In sections of a Javanese trap-door spider he finds that these organs differ very materially from those of the hexapods and agree with those of the amphipods, in the fact that they are diver- ticula of the mid rather than of the hind gut. As to the develop- ment of these organs in the spiders almost nothing is known, the two most recent authors on arachindan embryology—Locy and Schimkewitsch—having nothing to offer on the subject. The bearing of the observations of Loman tend to show that these organs are not homologous in all the “ Trachcates,” and possibly that the arachnids and crustaceans are more closely related than is admitted in most text-books. THe MYLOHYOID GRoovE IN THE Mesozoic AND RECENT MAMMALIA.—The Mesozoic Mammalia subdivide into two series, nerve and artery branch at this orifice, part entering the canal, 76 General Notes. part extending along the inner surface of the ramus, as the mylo- hyoid nerve and artery, to supply the mylohyoid and digastric muscles, There is thus little doubt that this groove lodges this artery or nerve in all these recent forms, as it does in man. 4°. In all the mesozoic mammals in which the groove is present it inva- riably extends from near the orifice of the dental canal, for a greater or less distance, along the inner face of the ramus, some- times descending rapidly to the lower border (Phascolotherium), sometimes reaching the symphysis (Amblotherium). From its con- stant relation to the dental canal and variable development I think there is little room for doubt that this groove lodged either the mylohyoid nerve or artery; at least there is no ground for any other supposition. 5°. Dromotherium, from the Triassic, the old- est of the mammals of Series B, presents an exception; I cannot discover the orifice of the dental canal in its usual position; the anterior border of the pterygoid fossa is not clearly defined, as in all the Jurassic genera, but gradually closes into a long, narrowing groove, which suddenly terminates in an orifice in the middle of the ramus beneath the last premolariform tooth. It appears as if the inferior dental nerve and vessel may have lodged in the groove and entered the jaw at this anterior point. From all these data I see no present ground for changing the designation of this groove in the Mesozoic mammals, as employed by Owen, but strong reasons for not attaching any great taxonomic value to its presence or absence.— Henry F. Osborn. THE INTER-CONNECTIONS OF SMOOTH MuscuLaR Frsres.—Dr. N. Kultschizny states (Biol. Centralbl., 1887) that smooth-muscle fibres are not connected together by the oft-described intercellular cement, but by means of minute protoplasmic fibres, and that tween the cells exist intercellular spaces. A similar view has been held and taught for some time by some American histologists, and these even go farther and trace in the existence of these intercellular bridges, the evidence for evolution of all meso-dermal tissues from an epithelium. THE Fauna RELATIONS or FERNANDO Noronna.—At the meeting of the Linnean Society of London, November 3, 1887 there. The cliffs are steep, but otherwise the soil is fertile; there is an absence of sandy bays on the south side. Generally speaking; the specific animal forms differ on the opposite sides of the maim island. The indigenous fauna and flora seems to have been Zoology. 77 much modified, and in some cases extirpated by human agency. Of mammals, the cat is reported to have become feral, and rats and mice swarm ; Cetacea occasionally frequent the coast. The land birds comprise a species of dove, a tyrant, and a greenlet (Virio). Sea birds are numerous, but by no means so abundant as they were formerly when the island was first discovered. Among the reptiles were found a species of Amphisbeena, a scink (Huprepes punctatus), a gecko; turtles are also frequently seen in the bays. Batrachians and fresh-water fish are entirely absent. One butterfly, a well- known Brazilian species, was plentiful; but insects, though abun- dant, were poor in number of species. Two species of Trochi called for remark as having a southern distribution, the remainder of the marine shells, and indeed most of the marine fauna and flora, show affinities to that of the West Indies. Muscues or Brrps.—The researches of the late A. H. Garrod in the line of avian myology, did much to place the classification of birds upon a firm basis, as may be seen in any recent ornithological treatise of value. He showed that the peculiarities of certain mus- cles could be made of value in indicating the affinities of the different genera families, etc. Garrod’s work has recently been presented to the American students in the shape of an illustrated review by Dr. Shufeldt, in the Journal of Comparative Medicine and Surgery for October, 1887. Dr. Shufeldt does not discuss the laryngeal muscles, but he adds to the muscles employed by Garrod the dermo-tensor patagii, as well as calling attention to the syste- matic value of vther characters than the mere presence of Garrod’s classificatory muscles. A GULAR GLAND IN THE BANDED ANT-EaTER.—Mr. F. E. Beddard calls attention (Proc. Zool. Soc. London, p. 527. 1887) to a remarkable glandular structure just in front of the sternum of the banded ant-eater (Myrmecobius fasciatus) of Australia. In the region of the gland the integument is naked and studded with the apertures of the glands of which there are four distinct kinds: (1) sweat glands; (2) sebaceous glands; (3) sudoriferous glands; and (4) a large compound tubular gland. Of these, 1, 2, and 3 are confined to the integument, but the fourth is situated in the con- hective tissue underlying the dermis. The duct of the last has not een found. Histologically it resembles a sweat gland, and is divided by partitions of connective tissue. THE MAMMALIA OF THE MaraGHa Bep.—A report on this Subject by Dr, Kittl is published in the last number of the Annalen of K. K. Naturhistorischen Hofmusewms, of Vienna. The species obtained number twenty-two, of which more than half have been Previously discovered at Pikermi, near Athens, and the others do not indicate any wide difference of fauna. Among the peculiar 78 General Notes. species may be mentioned the rhinoceros, Aceratherium blanfordi Lydd , and Hippotherium richthofeni Koken. Prominent Pikermi forms are—Macherodus leoninus R. -5 Palworeas lindermay- eri, Helladotherium duvernoyi Gaudry ; Mastodon pentelici Wagn. ; Palhyena hipparionum Gerv.; Hyena eximia Wagn., and Sus erymanthius R. & W. Dr. Kittl deecribes the Carnivora in the present paper. He finds the following new species: Macherodus orientalis K., Meles maraghanus, and Meles polaki. The Machero- dus is one of the smaller forms, allied to M. megantereon, but was a formidable animal—as large as a full-sized leopard. Maragha is in Persia. The horizon is Upper Miocene, or Mio- pliocene. ZOOLOGICAL NrEws.—GENERAL.—Observations on the structure and distribution of stripe and unstriped muscle in the animal king- dom, conducted by C. F. Marshall, go to show that the striped form is found in the disc of meduse, but not in Actinia nor in Echino- derms. Some Vermes show moths, as the Arthropoda and the Arachnida possess the striped form; but the Leech and the earth- worm are without it, and the mollusca which possess it are those which, as Pecten, move rapidly. An intracellular network is always present in striped muscle-fibre, and this network is developed where rapid and frequent movements have to be performed. The contrac- tion of the striped muscle-fibre is referred by Mr. Marshall to the action of the longitudinal bars of the network, while he considers the transverse fibres as passively elastic, and by their rebound as causative of the relation of the muscle-fibre. The cardiac muscle cells contain a network similar to that of ordinary striped muscle. ARTHROPODA.—The development of Peripatus Nove-Zealandi¢ is described by Miss Lilian Sheldon in the Quart. Jour. Micros. Soc., Nov., 1887. The species is viviparous; the segmentation resembles that noted by Henking in certain Phalangide ; and the embryo derives nutriment partly from the yolk within its body, partly from a peripheral layer. FisHEes.—Professor D’Arey W. Thompson states (Ann. and Mag. Nat. Hist., Sept., 1887) that the blood-corpucles of Myxine, instead of being small and round, like those of Petromyzon, are large and oval, like those of skates or dog-fish. POLYPRION PROGNATHUS, the Hapuku of New Zealand, and one of the most esteemed food-fishes of the Southern Hemisphere, 15, according to Dr. A. Giinther, identical with Polyprion ’ described by Steindachner, from Juan Fernandez. It is therefore widely distributed and antipodal to the only other species known, — P.cernium. The latter is shown by Lowe (Fish. Madiora, p. 185) to be a deep-sea fish, swimming near the surface when young, but when adult living at depths of 300 fathoms or more. Zoology. 79 In one of the numerous ichthyological papers emanating from the Indiana University, Carl H. Eigenmann and Eliz. G. Hughes give a review of the North American species of the genera Lago- don, Archosargus and Diplodus. The first has one species, while the second and third are represented in North America by four and seven species respectively. Mr. Eigenmann also describes Ophich- thys retropinnis, from Pensacola, Fla. Miss Rosa Smith bases a new species of Rhinoptera upon a pair of jaws found at Todos Santos Bay, Lower California. BATRACHIA AND REPTILIA.—G. B. Howes (P. Z.S., June 7,1887) points out the existence, in the larynx of some Salientia, of a struc- ture which he believes to be homologous with the epiglottis of the higher Amniota. These are in the form of two papil'ate folds, constituting a forward prolongation of the laryngeal mucous mem- rane. Posterior to these some Anura have also a pair of folds, which Mr. Howes entitles epilaryngeal. The epiglottis is entirely membranous, and has little if any connection with deglutition. It seems to be purely an accessory voice organ. The Batrachian lar- ynx, like the Reptilian, is without a distinct thyroid cartilage. The author gives a list of the species in which the primitive epiglottis, the paired condition of which resembles the initial stage of the development of the organ in the human subject, was observed. Some species of Hyla are without the folds, while they are present in others. The Bulletin of the Essex Institute, 1887, contains descriptions by Mr. S. W. Garman of the Iguanide and Scincide of the West Indies, at present in the Museum of Comparative Zoology at Cam- bridge. No less than twelve species are added to the genus Anolis, each species apparently restricted to a small cirea. The scincoid genus Mabuia is also enriched with three new species. Mr. Garman has also published a list of the Reptiles and Batra- chians of Grand Cayman, an island of the Caribbean Sea, about 200 miles south of Cuba. Grand Cayman is of coral formation, rises but little above the sea, and must have received its land ani- mals from the neighboring islands not so very long ago. An Anolis and a Liocephalus are described as new. Mr. Garman has recently added to the snakes of the West Indies Ungualia curta, Dromicus cubensis, and D. ornatus, Alsophis pul- cher, and Trigonocephalus caribbæus. A small turtle, Cinosternum Sp., sent to Cambridge by Professor F. Poey, seems to possess dis- tinct specific characters. 80 General Notes. G. A. Boulenger (Ann. and Mag. Nat. Hist., July, 1887) describes several new Reptiles and Batrachians in the British Museum, includ- ing an Anniella and a Hyla coper,! from Texas; and an Eiemias from the Guinea Coast. s Years ago Dumeril and Bibron described an Australian snake under the name Furina textilis. It has been omitted from all recent lists of the reptiles of Australia, upon the sup- position that it was based upon the common Diemenia supercil- iosa. ecently, Mr. Froggat has rediscovered the species in the neighborhood of Port Darwin. MAMMALIA.—Among the few beaver colonies still existing in Europe is that at Amlid, some distance from Christiansand, Nor- way. Sometimes as many as a dozen animals may be seen here in the water at one time. Their huts are built close to the shore, and have two stories, one above and the other below the water level. The walls are of timber, the roof of ‘twigs and mud. The beavers have felled all the aspen-trees in the vicinity, and have begun to attack ‘the birches. They cut down trees upwards of eighteen inches across at the root, but do not seem to use the larger trunks. The branches are dragged to the water-side along regular “ log-runs,” which are cleared of interloping roots. Sentinels are posted to give. the alarm in case of danger, when all the animals leave their dwell- ings for the water. A new species of Spermophilus (S. bactrianus Scully) and Ello- bius intermedius Scully, are among the mammals collected by Cap- — tain C. E. Yate, of the Afghan Boundary Commission. E. P. Ramsay has recently described three new mammals (Antechinus froggata, Perameles auratus, and Mus burtoni) from North West Australia. Worms.—In the fresh-water Dendrocelous planariansis an | organ which is usually termed the uterus. Ijima rega this as a gland for forming the egg cocoon, and the latest student (Hallez) agrees with him. Hallez regards Ijima’s muscular gland as a force-pump to drive the male elements. into the cloaca, — and that possibly to expel the ova and cocoons. Its resemblance in certain particulars to the bursa copulatrix of the Rhabdocoela 15 pointed out. Brirps.—Dr. W. A. Haswell, of Sydney, N. S. W., recently read | a paper before the Linnean Society on the early stages of the emu, detailing the history of the primitive streak, mesoderm, neurenteri® — 1 The H. arenicola Cope.

As the embryology of no member of the Ratite or Struthionidew has ever been studied, Dr. Haswell’s work when published will have no little value. PSYCHOLOGY. EVOLUTION AND IpEALISM.—The doctrine of idealism is natu- rally attractive to the minds that believe in mind. To feel that mind is all in all, and is not bound to “ low material things,” is as agreeable to the metaphysician as it is to the seeker for immortality. Moreover, the doctrine seems to have a certain support from the scientific side. We know that our knowledge of what are vulgarly supposed to be the properties of matter, is not derived from a sin- gle sense, and we readily understand that those properties would appear to be greatly modified, were the number of our senses re- duced or increased. Moreover, we know from experience of the abnormal or diseased states, both of ourselves and of other men, that the appearances of the objective world may be wonderfully modified by changes in ourselves. The hallucinations of delirium and other forms of mental disorder, are matter of every-day knowl- edge ; and the illusions that may deceive even the healthy mind are equally well known. The question between the realist and the idealist is, what do these facts prove? ey certainly do not prove that a universe which presents in its parts, and therefore in its entirety, the two properties of extension and resistance, has no existence, They certainly do prove that our knowledge of such universe and of its parts is imperfect, It is to remedy this imperfection, and to enlarge our knowledge that many men spend much labor and time. And the knowledge thus acquired and exactly systematized, is called science. The pursuit of science postulates the existence of that which it pursues, not as states of consciousness, but as objective realities. There are reasons for the soundness of this view, which I propose briefly to enumerate. If a given supposed object be in reality a purely mental state on the part of the subject, a rational cause for the production of that State is wanting. But letting this difficulty pass for the time, and letting it be supposed that there is some apparent undefined cause ye the departure of the second person, it ceases to exist for him ut continues for the third person, and so on. In the presence of these facts, consistency requires one of two conclusions, on the part of the idealist; either he must deny the validity of the mental states 4 $2 General Notes. of other men, or he must believe in the Hegelian aphorism, “ Exis- tence and non-existence are identical.” Some idealists adopt the one, and others the other of these two horns of the dilemma. But the difficulty is immensely increased when we contemplate the mental lives of the lower animals, with their varied sense organs and media of contact with the so-called material world. We can readily imagine the limitations under which many of them exist through their structural deficiencies ; but we cannot so well imagine, though we are compelled to believe in the wonderful acuteness of the perception, and the to us incomprehensible peculiarity of sensa- tion, produced by the various special organs of sense with which many of them are furnished. Think of the tactile sensibility to slight movements of the water possessed by the blindfish of the Mammoth Cave. Think of the sense impressions of which we know nothing conveyed by the antenne of insects. Think especially of the “ other world than ours,” in which many of the Mammalia live, in consequence of the high development of the olfactory sense. We can easily perceive the result of the idealistic reasoning on the part of the inferior animals, were they capable of it. To many of them mankind would not exist; to others the sun would be a fiction. Those to whom low tones are imperceptible, would deny the existence of the only vibrations that some other species is adapted to hear. The idealistic position which denies the existence of matter, results from a process of cancellation of the objective universe bit by bit. One animal after another, and one sense after another, are proven fallible, and so the entire objective superstructure disappears. The realist, on the other hand, adds together all the phenomena derived from all the senses of all conscious beings, thus getting a positive result, where the idealist gets a negative one, Which is the more rational of the two methods? The actual result to thought is, that we learn the insufficiency of each and every sense, but not its impo- tency, We are instructed that our true policy is to use our senses to the best purpose, and to add to their number, so that the defect of our knowledge may be remedied, and our mental vision enlarge more and more. And this is the mission of science. But all knowledge, we are told, is relative, and that of the absolute _ reality we can learn nothing, This doctrine does not necessarily — involve idealism, but it is necessarily held by consistent idealists. One can believe in a material universe and still hold that we do not know it absolutely or even truly, And as “ weareall poor creatures, many of us are prone to repeat “ great is the doctrine” of the Rela- tivity of Knowledge! And the scientist echoes, but in a different spirit, great is the doctrine of the Relativity of Knowledge ; ye great is our Ignorance! Great is our ignorance indeed, but not “ great is Ignorance!” The scientist does not worship ignorance ; he worships knowledge, and his occupation is to increase knowledge. To the responsive intellect and enterprising spirit, the knowledge of our ignorance is the stimulus to unceasing labor, To men of amore — Er SEN INDIRE E Sa TE ES R R Psychology. 83 lymphatic temperament the knowledge of ignorance seems to paralyze théir lives. But science has done much towards elucidating the order of the universe, and will do more. Evolution gives the coup de grace to idealism of the consistent type. In the gradual unfolding of organic life it sees the two uni- versal facts, subject and object, It sees them interact and influence each other. Under the influence of active, conscious life thousands of tons of substances are transported from place to place and meta- morphosed in the process, Under the influence of life, from which consciousness may or may not be absent, thousands of tons of matter have been made into soil, rocks, and living tissue. On the other hand, the objective environment has constrained all living things into rigid modes, and has extinguished millions. In the midst of all this turmoil, consciousness has picked and wound its way, ever gaining in strength and skill, till now we behold man, Of all ani- mals, man controls his environment most completely, He begins by making his own heat and light ; he makes his food to grow, and his skin is partly his own manufacture, He does this, and very much more, with infinite pains and toil, and yet some individuals of his species actually deny the existence of this environment, which has compelled him to be what he is! : It is equally competent for the materialist to deny the existence of mind, as for the idealist to deny the existence of matter. The materialist, beholding the imperfection of the senses, may pronounce them to be, one by one, incompetent witnesses, and declare them to be illusions. The mind, which is the product of these impressions, immediate or remembered, falls with them; it is also an illusion. But the fact is, both exist, cbject and subject, matter and mind. And since matter cannot study mind, mind must study matter, and by so doing grow to more absolute knowledge and greater control of its physical basis, and therefore of itself. It can now be seen why the study of the “problem of cognition” has little interest to progressive science, Its result is an expression of our ignorance in philosophical form, a proposition which the sci- entist is not disposed to deny. But when he asks the philosopher “what do you propose to do about it?” and gets the same old story reiterated from the old scholastics to the latest relativist, he turns from such blind guides to his own, and to nature’s laboratories, and goes to work, And the theologian applauds the philosopher, and says of the scientist in his prayers, “1 thank Thee that I am not as this section-cutter, this bug-hunter, nor even as this bone sharp.” But the scientist knows that he holds the key of the situation, and he lets the philosopher and the theologian rejoice themselves, each in his appropriate department of Swedenborg’s heaven. The field of Ideal- ism has been well worked out, and we of this age should thank the mighty men of the past for having done it for us. We can now go on with an easier mind in a more profitable pursuit. 84 General Notes. Doctor Montgomery’s last article in Number 21 of The Open Court, states at once the strength and weakness of idealism. Its principal weakness is that it is unable to stand alone without a good strong realistic prop somewhere behind. Thus the Doctor says (p. 587): “The tri-dimensional, hard, colored, sounding, scented, heated matter—fancied by Professor Cope and others to subsist out- side consciousness, and believed by them to be directed and organized by such consciousness—is, indeed, through and through, a fictitious entity, consisting of nothing but a set of our own percepts illusively projected into non-mental existence.” This looks like pure idealism, but he lets in a “non-mental existence.” Now what is this? On page 589 (bottom) he says: “Now the realistic assumption which the philosophy of organization here makes, is indeed, the simplest possible, and is in full agreement with given facts. It supposes that there subsist in nature non-mental existents possessing the power of specifically affecting our individual sensibility, and of manifesting their special characteristics by means of the different conscious states they arouse in us.” This is a little more definite, and the Doctor even calls it by its right name, a “realistic assumption.” This is quite to my liking, but I cannot perceive how such “ non-mental existent” can have less than three dimensions and still exist. And in order to prove to me that mind or consciousness has no control over this tri-dimensional “non-mental existent,” Dr. Montgomery must go into further particulars. He must prove to me than an animal does not eat or drink because it feels hungry or thirsty ; does not seek shelter on account of weather or temperature; exp í nothing in its voice of pain, desire or pleasure; that the horse does not run because he is whipped, or the bird build because it feels the necessity of laying, etc., ete. I must here protest against the misinterpretation of an expression contained in one of my earlier articles, which was not sufficiently guarded, it is true, to preclude such misconstruction. It is possible to say correctly that “ mind is a property of matter, as color an odor are properties of the rose,” without meaning to say that the two properties are such in the same manner, as is inferred by my critic (p. 589). My article in Number 19 of The Open Court is sufficiently clear as to what I understand by mind as a- property of matter, so that it is unnecessary to go into a fuller explanation. Suffice it to say that the conscious and the unconscious properties matter cannot be confounded by any rational thinker, and that such confusion is entirely foreign to my thoughts. More than one-thi of Dr. Montgomery’s article Number 5 is thus irrelevant, In the other two-thirds I fail, as yet, to find a definite theory which shall explain the apparent facts of designed movements of animals, dif- ferently from that which is held both by physiological science an by popular belief. That is, that the design in them is the direct result of a limited control which conscious states have, or did onc have, over the energy and the matter concerned in producing them- —E. D.

Sterna forsteri Nutt.—In spending my summer vacation two years ago at Piney Point, Mary- land, some ninety miles from Washington, I had abundant oppor- tunity to study the movements of this beautiful bird. Their elegant appearance, whether flying gracefully over the water in search of their food, or floating jauntily on a drift log, or darting swifty from place to place, makes them very attractive. I started out one fine morning, on a collecting tramp, and the sun, which had risen clear and bright, gave evidence of a warm, sultry day; but the wind, shifting, scattered the clouds over the sky, and a dull, rather cool day followed. I continued my walk to the river; the receding tide had leit a sand bar high and dry some twenty feet from the shore, and on this I noticed a flock of Forster’s terns, which took flight as I approached. I fired, one dropping dead amid the shrill cries of his companions. As the water was very shallow I commenced to take off my shoes and stockings in order to wade out and secure my specimen ; but, to my astonishment, the whole flock renewed their cries vociferously and commenced to circle around me, and from me to the dead bird, as if they knew that I was responsible for their companion’s misfortune. As I commenced wading, the birds seemed to ascertain my object, and they, with one accord, began to fly higher and enlarge their circle, and, flying faster than the rest of the flock, the first six or eight separated themselves in single file, and each one while flying, with a strenuous effort, gave the dead bird a push with its feet; each individual of the flock pushed in rapid suc- cession, and soon would have had the specimen beyond my reach if a friendly boat had not come along and rescued it and dis- _ persed the flock For a whole flock of birds to act in perfect unison and With one impulse, to remove a bird in the quickest and most effective manner, is certainly a wonderful performance, which can hardly be credited to instinct (as it is scarcely to be sup that the affection for members of a flock would be as strong for a mate as for their young).—P.

The extent of the jerk proved to be an index of the state of the nerves. The first series of experiments showed that the jerk obtained upon rising in the morning was small; that that given after breakfast was, on the average, higher than those at subsequent hours, and that it rese after each meal ; also, that the effect of muscular exercise was always to largely diminish its extent. Slight mental fatigue does not seem to affect the knee-jerk, while unusual mental fatigue produced an irri- tability which reinforced it. Irritation of the skin, voluntary movements, attention to unusual sounds, exciting mental work (such as the recitation of a stirring poem), music (especially of am emotional character), exciting dreams, all increased the extent of the knee-jerk. Violent respiratory movements also increased it, while a rise of temperature or a fall of the barometer diminished it, oppo- site meteorological conditions producing opposite results. A second series of experiments confirmed the results obtained by the first. ARCHZOLOGY AND ANTHROPOLOGY. THe Magic Mirror or CHINA AND JAPAN.—The magic mirror is the common toilet mirror or kKagemi in everyday use 1n Japan. It is a thin disk of cast bronze about eight inches in diameter, or of various sizes, and has a short handle cast with the piece. The plane side is amalgamated; on the back are repre- sentations in relief of bamboos, ships, storks, trees, etc., and gen- erally two large characters. oe The performance of this mirror has long excited great curiosity and interest, and there have been many ingenious conjectures as to the reason of the strange way of its reflection. The magic is that, when it is properly prepared and the sun’s rays caught upon 1t and reflected on a screen, the outlines of the characters and figures on the back show in the reflection. The figures appear lighter than the rest of the field, and not frequently with a sharp outline. Better results will be obtained if the mirror is slightly warmed, laid on its back on a perfectly flat surface, and briskly polish with acloth. Then, if the sun’s rays are caught upon it, at first in the reflection the figures cannot be seen, but they gradually appear and are permanent. In China its peculiarity has been long and well known, for it was spoken of with great admiration in the eleventh century by Tchin-Kouo, and the poet Kin-ma, celebrat it in verse. It is probably used as one of the very numerous agents of divination practiced there; and in passing, we note “er a mirror, the symbol of purity, is found in every Shinto temp! and shrine in Japan. The Chinese mirror has no handle; 1t 1$ held by cords passed through lugs at the back. Archeology and Anthropology. 87 They are called in China theou-kowang-kien, or mirrors that are penetrated by light, an expression which portrays a popular error. Ju-tsin-hing, who lived between 1260 and 1341, wrote on the subject as follows: “ Here is the cause of that phenomenon which proves the employment separately of fine and coarse copper. If they have produced in the founding in a mould a dragon arranged in a circle, on the face of the mirror they engrave deeply an exactly similar dragon. Then, with copper a little denser, they fill up the deep cuts of the chisel, submit the mirror to the action of fire, after which they level and dress the face and give it a light coating of tin. en its image is reflected on the wall, it presents the clear tints and dark tints which proves that the one is of the portions of purer copper and the other of the coarser parts.” ! He claims to have seen a broken mirror which was so constructed. Aside from physical reasons, the cheapness of the kagami refutes the idea of this extremely difficult process to make a common toilet article. An amusing interpretation of the riddle was brought out on questioning several Japanese. They said that magic mirrors are caused by earthquake shocks occurring just when the metal is being poured into the mould; the shock rearranges the particles and alters the reflecting powers. Workmen sometimes jar the flasks to produce the effect during the rare absence of an earth tremor in that land of seismic disturbances. Just how much magic comes from the great fish whose uneasy slumber causes earthquakes, according to Japanese folk-lore, has not been found out. However, in the course of these inquiries a fact was elicited of some importance. All mirrors are not “magic,” and they cannot be “made to order.” This may have some bearing on the theory or irregular tension relative to the pattern, and is a sufficient cause.

ANTHROPOLOGICAL NEws.—Ensign A. P. Niblack, U. S.N., has just returned to Washington from a three years’ voyage enthusiastic archeologist and has done good service to that science as the records of the Smithsonian Institution will abundantly show. He pushes his researches among natives whenever and wherever his duties permit. He returns loaded with ethnologic material, which he will now have the opportunity to classify and describe. He has perfected himself in photography, and returns with full series of Indian villages, houses, totems, burial posts and glaciers, which, jutting into the sea and breaking off, are caught in the act of transforming themselves into icebergs. Lieut. Niblack’s interest and studies have been directed to the Totem posts with which that country is so prolific. He says that winter is the only season when studies can be successfully made in the ethnology of Alaska. The natives are then at their homes prepared to give or receive pleasure or information. In the summer they are engazed some- times far inland on the mountains and inaccessible. Mr. E. A. Douglas, of New York, has returned to the United States after two years’ absence in Europe. i Mr. Douglas possessess one of the finest private Ethnographic collections in the United States. It was stored for safe keeping during his absence at the New York Museum, Central Park. - Mr. Douglas has now gone to Florida, where he will continue his studies until his return in May. His address is Saint Augustine. SCIENTIFIC NEWS. —The Middlesex Institute proposes to publish a Flora of Middle- sex County (Mass.), giving a complete list of the Phanerogams and VascularCryptogams.

It will contain laboratories for the study of both cryptogamic and phenogamic botany. There will also be rooms for the exhibition of the collections already accumulated, for which there is no adequate accommodation. The fund for building has already been raised, through the exertions of Prof. J. M. Goodale. A collection of Superb glass models, representing the principle species of flowering plants, is now being made in Germany, especially for this exhibit. When this addition is completed and the collections arranged, it will be surpassed by few in the world.

The following papers were read:—“ The East-West Diameter of the Silurian Island about Cincinnati,” by Professor D. W. Dennis: Professor Dennis alluded to the fact that at Richmond, Indiana, there was a thin bed of rock composed of broken shells of lower diluvium age, in its character much like coquina and indicat- ing an ancient shore line. Two similar deposits have been found in Adams and Highland counties, Ohio, and these give the means of measuring the east to west diameter of the Silurian island which existed when this rock was formed. In “ Erosion in Indiana,” J. T. Scovell maintained that at least seven hundred feet of erosion had taken place over the whole state of Indiana. He alluded to the ancient river channels corresponding in general to the present courses but wider and deeper, and stated that, of the drift material in the state, on the average five feet came from the state and fifty was of extra-state origin. A “Geological Section of Johnson County, Indiana,” by D. A. Owen, was an account of the strata p through in boring various wells. D. W. Dennis stated that the “ Transition of Orthis occidentalis unto Orthis sinuatu” was accom- plished in 300 feet at Richmond, Indiana, illustrating his point by numerous specimens. “Notes on Some Fossil Bones found in Indiana,” by O. P. Hay, was the announcement of the identification of the genus Tapirus in some bones found in a sink-hole m Monroe county. In zoology the papers were more numerous, but many of them consisted of the records of additions to the fauna of the state. Such was B. W. Evermann’s “ Fishes of Carroll County,” in which five species new to the state were enumerated, the most noticeable being Notropis arga Cope, “ Notes on Some Southern Indiana Fishes,’ ” by O. P. Jenkins, and “Some rare Indiana Birds,” by Amos W. Butler, were of a character expressed by their titles. B. W. Evermann noticed “ the Occurrence of the Star-nosed Molein Indiana; A. W. Butler, in his “ Notes on Indiana Reptiles and Amphibians, added Plethodon cinereus, Hyla squirilla, and two new species 0 Entenia to be described by Professor Cope to the fauna of the state. The “Additions to the List of Indiana Reptiles,” by O. P. Hay, were Cinosternum pennsylvanicum Tropidonotus rigidus, and Cnemid- ophorus sexlineatus all on the authority of Robert Ridgway. , In 1869 Dr. Günther enumerated 193 species of fish occurring 0” one side or the other of the Isthmus of Panama, of which about one- third were regarded as common to both the Alantic and Pacific sides. D. S. Jordan, in his paper, “The Isthmus of Panama as _4 Barrier to Marine Fauna,” stated that now there were known 1370 species from the same region of which but five per cent. were com- mon to the Caribbean and the Pacific shores. With these data the recent connection of the two seas is not so probable as Dr. Günther $ Proceedings of Scientific Societies. 95 fish figures would makeit. Ina paper on “ Blind Fishes and National Selection,” D. S. Jordan replied to the statement in some religious paper that “evolution would find it exceedingly difficult to account for these forms.” In “The Origin of Genera,” the same gentleman gave an outline of the view of Professor Cope on this subject and mentioned some of the difficulties which were presented by fishes, at the same time indicating the great aid which systematic zoology had received from the same theory. “The Origin of Arthropods,” by J. S. Kingsley, was a résumé of recent views on the origin and lines of descent of the various groups of arthropods. © O. P. Hay, in his “Observations on Amphiama,” gave some interesting facts regarding this batrachian. In Arkansas he found an Amphiama incubating her eggs under- neath a log. She was coiled around her eggs and was very sluggish at first. Later she was quite cross and irritable, uttering a shrill sound like a whistle. The eggs, of which there are about a hun- dred and fifty, form long stings, the gelatinous envelope shrinking between the eggs so that the whole sting resembles a sting of beads. The young which were in an advanced stage of develop- ment were about one and three fourths inches in length with well- developed gills, each bronchia consisting of a main stalk with three feathered branches. The eggs themselves were about the size of a pea. . W. Hargitt had two papers: “Curiosities of egg formation,” and “ Notes on Scaphiopus holbrookii.” The first detailed some cases of teratology in the eggs of hens and turkeys; the second an appearance of the spade-foot toad at Marthas Vineyard during a heavy rain during the past summer. A. W. Butler made some “Suggestions concerning a law for the Protection of Birds,” stating that the present law would not stand, and that it is impossible tọ secure convictions under it. A committee was appointed to urge the passage of a suitable law embodying the provisions of the New York and Massachusetts statutes upon the next legislature. Maurice Thompson’s “Secondary functions of the Hyoid corma in icus and Colaptes” showed a lack of morphological and physiological knowledge. ‘The address of the president, John M. Coulter, was delivered Wednesday evening, and with “Evolution in the Vegetable King- dom,” tracing the origin of the sexual element in plants, and the radual increase of the asexual over the sexual generations. Besides this there were six papers read on botanical subjects. Miss Lillie J. Martin spoke of the “ Value of Organized Work in Plant Chemistry ;” J. N. Rose mentioned the “Characters in Umbelliferee,” which he found of most value in the classification of this group of plants while working them up in connection with Professor Coulter for the Synoptical Flora. The most valuable characters were found in the fruit. Stanley Coulter spoke of the “ Histology of the leaf of Taxodium distidium.” He found the cell walls difficult to study on account of their thinness and the large cell 96 ‘General Notes. spaces. He described the strengthening cell system and the resin- ducts. The fibro vascular bundle in the centre of the leaf showed traces of its formation by the coalescence from two primitive bundles; whether these remained distinct at the tip the author could not say. There are eight stomata in each leaf, six above and two below. John M. Coulter described the peculiar structure of the “Stornata of Tillandia usneoides.” The scales which give the Spanish moss its pubiscent appearance are to be regarded as leaves since each bears a stoma. Surrounding each stoma is a trichoner structure, in the centre of which are four sensitive cells. Below these comes the true stoma with its two sensitive guard cells. Experiments with the plants showed that this peculiar structure was to be explained by the epiphytic habits of Tillandia and the trichonu structure must be regarded asa reservoir of moisture. Walter H. Evans, in -an account of the “Lichens of Indiana,” gave an account of the habits and structure of Lichens and the methods of collecting these plants. He stated that he had already recognized seventy-six species of Lichens in the state, distributed among twenty-eight genera. J.C. Arthur detailed his investigations on the “ Life History of the Plum-leaf Fungus.” He found that the summer spores cannot withstand the winter but that soon after the leaves fall to the ground there is a new formation of minute winter spores, the sub- sequent history of which he had not found out but which he was inclined to regard as male sex spores. No other spores were form in winter but in spring the fungus took on a new development — with the formation of ascospores which ripened in June. From these the leaves were infected and a new growth of the fungus took place. a The last paper was “Man an Evolution—Biological proofs,” by T. B. Ridding. The author accepted the principle of evolution — but claimed that there must be successive additions of Divine — power in order to account for the existing fauna and flora and for the appearance of man. d Committees were appointed looking towards the purchase, of | scientific works by the State Library and to invite the American Association for the Advancement of Science to hold a meeting % Indianapolis in 1889. It was voted to hold the spring meeting of 1 the Academy May 9, 1888, at Wyandotte Cave. The followmg of Greencastle. It was voted that the past presidents of the Academy be added to the executive committee. - VE ew aS ee ee T Duet Se le gy Eo AMERICAN NATURALIST. VoL. XXII. FEBRUARY, 1888. No. 264. ON METEORITES.’ BY DR. HANS REUSCH. Wt know that in the organic world, besides the larger animals and plants, there exist immense numbers of living beings of diminutive size, from those barely visible to the unaided eye down to those which can only be discerned in powerful microscopes, and of which many thousands live in a space no larger than a drop of water. Similar is the case with the heavenly orbs revolving in the infinite space. Besides the big luminaries, numerous swarms of very small bodies are hurrying through the space in their different varying orbits. To the smallest of these—the so-called meteorites '—I here wish to call your attention. There is a circumstance which imparts them with a special interest to us; for they some- times fall to the earth, so that we are able to lay hold of them, touch them with our hands, study them chemically and microscopi- cally—in short, examine them by all the means available to us for a scientific investigation of their nature. The meteorites thus form a kind of connecting link between astronomy "and mineralogy— sciences otherwise rather distant, but which in this instance are brought to mutually throw light upon each other. It is probable that, on an average, several meteorites reach the earth every day, but many falls occur at night, while others drop into the sea, are lost in deserts or in places inhabited by ignorant people. ta going over the falls of meteorites which have come to our knowledge, it appears that no more than four or five cases a 1 A lecture delivered at the University of Christiania, Norway. 98 On Meteorites. year, on an average, are recorded; and in but comparatively few instances the fallen stones are hunted up by people in order that they may become of use to science. ‘The meteorites, therefore, owing to their variety, rank among the most precious treasures of the mineralogical museums. To illustrate the value generally attached to them, it may be mentioned that after it had become known that the meteorite found last year at Tysnæs, Western Nor- way, had been acquired by the Christiania Museum, a mineralogist was dispatched by the Riks-museum, in Stockholm, Sweden, the long way across the Scandinavian Peninsula, in the hope that he might be able to pick up some fragments. A chief ‘object of this paper is, therefore, to call the attention of the public to the meteorites, in order to prevent possible falls from being passed unheeded. The attention once aroused, it may also be possible to ferret out meteorites, the fall of which, in former times, has been kept a secret, owing to the superstition that, reduced to a powder, they might serve as a medicine for man and beast. In Norway, for instance, they were known as “thorelo”—i.e., “lo,” or wadding of Thor, or thunder—the belief being that they fell during thunderstorms. Not all the stones which have been pre served as “thorelo,” however, are meteorites by any means, many — - of them being only common pebbles, pieces of pyrites, or some other _ kind of mineral. ’ - After these preliminary remarks, I shall proceed to the special — subject of this paper—the meteorites and their nature—to be treated ‘ of in three separate sections, viz. :— a (1) The phenomena accompanying the fall of meteorites ; (2) a Their mineralogical nature, and (3) Their position as celestial — bodies. 7 The circumstances under which the fall of meteorites occur being rather similar in most instances, we may take, for an example, a fall of the Tysnæs meteorite. It occurred on the 20th of May, f 1886, near the farm called Midt Vaage, situated on the Island of ft Tysnæs, south of Bergen, Norway. Between eight and nipe o’clock in the evening the inhabitants in a wide circle of surround- : | ing country were frightened by a loud report, which most of them — took for a clap of thunder, the stone falling down immediately after 7 the report. I have myself examined two grown-up persons who witnessed the meteorite coming down from the air. One was? woman working in a potato-field. She heard a loud noise, and, On Meteorites. 99 looking up into the sky, observed a black mass of clouds, from which she thought she heard a cracking sound, repeated five or six times, upon which the stone fell with a whizzing and rumbling noise a little distance off. Dust arose from the spot where it struck the ground. The woman walked up to where it fell and saw a hole in the ground, but found nothing else, as the meteorite had bounded off several yards from where it first struck. The other eye-witness —a man who was a little further off—was just going home after having finished his day’s work. He heard the report, and shortly after saw the stone coming down, “like a shot bird.” No fiery display was noticed at the place; but people who witnessed the phenomenon from a distance of several miles (a Norwegian mile about equals seven English miles)—as, for instance, in Bergen and in Vossevangen—observed a fire-ball darting with great speed across the sky and then exploding in the direction of Tysnes. Comparing the accounts of the direction of the fire-ball by the different observers, it appears that the meteor must have moved nearly vertically towards the earth’s surface. That the fire-ball escaped the notice of those on the spot may be accounted for by its being right above their heads, as one seldom notices what occurs right over one’s head. Their attention was first attracted by the report ; but as this, of course, was heard a considerable time after the explosion of the fire-ball, the fiery display had ceased long before the thundering noise could reach them, after which some time again elapsed before the stone fell. The man pointed out to me the corner of the field where he was standing at the time he heard the report; when the stone fell he had nearly reached his house. In ascertaining the distance, he found that it took him about one minute and ten seconds to walk from one place to the other. Judging from the space of time which elapsed between the report and the fall, the explosion must have taken place at a very great height above the surface of the earth. With due regard to the traveling speed of the sound and the probable celerity of the fall, the height may be estimated at twenty to thirty thousand metres; but any certainty. cannot be arrived at. The next morning a girl living close by found a big, black stone lying in the grass. She put it aside, but did not mind it any further ; and people’s attention was not called to it before it was _ rumored that a stone had been seen falling from heaven. The fol- lowing Sunday the curious stone formed the ‘main topic of a en a ee. ela yee wie es eS ee, ee a Oe ee at. F ii = ‘i F ta 100 On Meteorites. conversation among the people assembled at church. An emigrant Norwegian, on a visit home from America and about to return to this country, made a bargain with the poor woman on whose land the stone was found: he was to take it away for a mere song; and the Tysnæs meteorite came thus very near going to America. On coming home, however, the woman became uneasy at the idea of selling such a God-send—direct from heaven—and she returned the money. Shortly after, the district physician, Mr. Gjestland, heard of the stone, and, realizing its great scientific value, he at once took it into his charge. It is owing to this gentleman’s most obliging intervention that the stone—against a handsome remuneration, of course—was secured for the University of Christiania. This meteorite weighs about forty pounds. Several smaller fragments were also found. The phenomena mentioned above—viz. : a fire-ball rushing along and exploding with a thunder-like report, ‘followed by the coming down of the fragments—are those regularly observed accompanying the fall of meteorites. In some cases the velocity of the fire-ball has been ascertained to be sixty to seventy kilometres a second. This tremendous velocity accounts for the fire phenomenon, as the atmos- phere, not being able to escape before the missile, becomes conden- — sed to an enormous degree—a great quantity of heat thus being developed, according to the known physical laws. The meteorites, at one time having the temperature of space through which they — were rushing—a temperature far below the freezing point—will thus become enormously heated on the outside when entering the earth’s atmosphere. The pressure of the strongly-condensed atmosphere finally exceeding a certain limit, acts as a blasting-agency, according — to a commonly-accepted opinion, and the fire-ball explodes. The fragments are still glowing for a while after the explosion, but, % a rule, they have probably become cooled off when reaching ground. Nor is the final speed very considerable, the origi velocity of the fire-ball having been diminished by the resistance the air. 7 When falling at full speed, the surface of the meteorites may be f supposed to be continually melting—nay, perhaps, evaporatmg — By the friction of the air, however, the molten substance is remov® — almost as fast as it is formed. In this way the “ fire-tail ”—whio® _ the observers in many cases affirm having seen—may be explain a | In the same manner the “smoke” is formed which, on several 0c f 4S hay Oe On Meteorites. 101 sions, has been observed floating in the wake of the fire-ball, after the latter has disappeared. Several people assert that such a smoke was also seen accompanying the Tysnes meteorite. The fallen Fig. 1. The Tysnes Meteorite. stones show various signs of intense heating in the atmosphere, to which we want to direct the attention. In some cases, when stones have been taken up shortly after striking the ground, they have still been warm. In one instance it has been related that the fallen stone was at first so hot as to burn the fingers, and afterwards turned so cold that it could not be held in the hand for that reason. This may be regarded as very probable, when we consider that the heat- ing in the atmosphere only lasts a few seconds, and that its action, Consequently, must be quite superficial. Space, on the other hand, as an exceedingly low temperature, and the freezing coldness of the interior of the stone will therefore soon lower the temperature of the surface. The interior of the meteoric stones, as a rule, is gray or whitish ; the exterior, on the contrary, is covered with a blackish crust, which, on examination, proves to be the stony substance, having undergone a melting process. It is difficult to tell what shape the meteorites — have before entering our atmosphere, as we only gather bits and fragments after the explosion. These show the effect of the com- Pressed and intensely-heated air. The edges of the fragments, originally sharp, have become rounded, and on the surface there appear deepened marks, many of which look as if the stone had 102 On Meteorites. once been soft as a dough in which the kneading-fingers had left their impressions. The air has had a consuming effect on the stone —much in the same way as a powerful jet of sand acts on a solid body. Mr. Daubrée has experimentally imitated this remarkable effect of the air. Not being able to move a solid against an. aéri- form body with sufficient speed—as is the case with the meteorites —he chose to proceed in the opposite way, making air strike solid bodies with great vehemence by exploding dynamite cartridges against an iron rail. The result of the experiment showed that the gases, suddenly developed by the dynamite exploding, produced hollows even in a body of such resisting-power as an iron rail, and the form of the impressions—in this as well as in his other experiments—corresponds exactly to those found in the meteorites. Having now considered the phenomena accompanying the fall of meteorites, we shall now direct our attention to their mineralogical nature. The meteorites may be classed in two primary groups: stone- meteorites—to which belongs the Tysnes meteorite—and iron- meteorites, which consist chiefly of this metal. The two principal minerals composing the stone-meteorites are eustatite and olivine (or chrysolite)—both of which are also found on our globe, though rather rare—besides which these meteorites also contain grains of native iron, as an occasional sprinkling, through the mass. Examined by the microscope, they exhibit a structure which proves that origin- ally and before entering the atmosphere they were formed out 0 melted masses by congelation. Fouqué and Michel Lévy have produced, artificially, the structures mentioned by melting together suitable substances. It thus appears that these small heavenly bodies, in precisely the same manner as the crust of our own globe, consist of originally molten masses, having afterwards become sol- idified. Inthis connection, it may not be out of place to remind one > — of the fact that the interior of the earth consists of substances heavier than those most commonly found on the surface. The meteorite 18 also heavier than common stone; and it has been conjectured (with several reasons to support this hypothesis) that the interior of the earth consists of a substance similar to that composing thè — meteorites. On further examining the meteorites, it is found that after having passed through the original congealing process they have undergon® several changes on their way through space. In many cases it 1$ | On Meteorites. 103 evident that their substance has been broken into small pieces, which again have become cemented together—a structure seen with un- common distinctness in the Tysnæs meteorite, as represented in the accompanying cut (Fig. 2). Not all the fragments are so large as to be seen by the unaided eye; for in ex- amining the stone by the microscope some very small ones are also found, mostly of a round or globular form. This breaking up and putting together again seems in the case of the Tysnæs meteorite to have oc- curred at least twice. The large fragments seen in Fig. 2 are composed of smaller ones, it being a case similar to a conglomerate in which the individual roll-stones . a FıG. 2. Braccious structure of the consist of conglomerate. Fig Tysnæs meteorite, Drawn by the author. shows a portion of the Tysnæs meteorite viewed in the microscope; while Fig. 4 represents an isolated globule of olivine, greatly magnified. It contains a brownish and glassy substance, in form reminding one of the cells of plants. Similar formations, not rare in meteorites, have furnished a fanciful scientist an excuse for obstinately asserting that they actually are the remains of plants. It is to be regretted that such 18 not the case ; for it would undoubtedly have been interesting if in this way we had been able to lay hand on specimens of organic life from other globes. : : The second group of meteorites consist of native iron—as men tioned above—with an occasional sprinkling of grains of stony minerals, Native iron occurs but rarely on this globe, as iron readily enters into combination with oxygen—in other words, it oxidizes, or rusts. In fact, it isso rare in nature, except in the meteorites, that any lump of iron produced by man was formerly believed to have fallen down from heaven. This was also Norden- skiéld’s impression when, some years ago, he found quite a quantity of native iron in Greenland. The find was at that time much talked - of; but Steenstrup afterwards pointed out that the supposed meteor- ites were only big lumps of iron which had weathered out of the rock on which they were found. This rock abounded to a remark- able degree in iron. 104 On Meteorites. The iron of the meteorites, as a rule, contains more or less nickel irregularly distributed through the mass. If the polished surface of the meteoric iron be exposed to the action of some acid, there will appear peculiar linear designs, called the “ Wiedmannstitten figures” (after the discoverer), the acid attacking the iron J WAY containing nickel to a less degree than the pure MANNII, | Q z NN € metal. AN \ AS È E = AY \ We will now direct our attention to our third sub- ject, and consider the meteorites as celestial bod- jes. Before entering into this, it will be necessary, how- ever, to say a few words in regard to shooting-stars and comets, these being the celestial phenomena with which the meteor- ites are most nearly com- parable. To a common observer; who does not make a spe- nifed 6 times. Globules composed of enstarite cial study of the heavenly Festa meee pe o, grain of olivine vault, it looks as if the shooting-stars move quite irregularly—now in this direction, now in another. If, howeve?, their courses be carefully traced on an astronomical chart, it will be found that in most cases they radiate from certain points in the sky —-a great many of which have already been ascertained. That the shooting-stars come from a certain point means that they are moving from that section of space towards the earth, the radiation being only the effect of the perspective as they move from the distance ™ the direction of the observer. The best-known swarm of shooting- ‘stars is undoubtedly the one which appears to radiate from the constellation of the Lion, and is passed by the earth on the 13th of November. As on this day extremely numerous falls of stars have been observed, with a regular interval of thirty-three years, 1t !$ On Meteorites. 105 evident that they belong to a swarm which, after a revolution of thirty-three years around the sun, returns to the orbit of our globe. The comets are apparently something entirely different from the shooting-stars ; for while the latter are quite small and only appear within the terrestrial atmosphere, the comets are bodies of immensely greater size,comparatively speak- oh oN ing, and moving at a very great Ncs ce we SEE NG ANA ve ‘distance from our little planet. 7 SE A 3 D w Ler Investigation shows, however, Wee fe WEA = that the orbits of both comets Y % | ae Maana d and shooting-stars have the same HENG f = ach r form, they being elongated conic } aan ben — A sections: hence their approaching ` SA from distant dark regions of space—now close to the sun, now again retiring to an immense distance from it.

The comets nearest to the sun, when tn their greatest proximity to that body, are exposed to an enor- mous heat, soon followed, as they retire, by a cooling off equally enormous. The strong influence of the sun’s vicinity on the comets shows itself, among thes things, in the well-known long tail, which they project on the further side from the sun, and Bur nature and origin of which is still rather mysterious. Neither is the true nature of the shooting-stars fully ascertained. Many of them, however, appear to be small solid bodies rushing through the air ; and there are a great many intermediate forms between the common shooting-stars and the big fire-balls which explode with a thunder- like report and emit meteoric stones. ! a * ‘ iy a i di. E Fi, 1 Mr. Sophus Tromholt, the author of the beautiful work, Under the Rays of Aurora Borealis, has sent me the following interesting or of a shooting-star :— One starlight but moonless Saturday night during November or 106 On Meteorites. In the meteorites we have, as seen, at last something palpable which we are able to study. It will therefore be of great interest to have their connection with the shooting-stars and comets more definitely established. The study of the orbits of the meteorites, however, is rendered much more difficult than that of the shooting- stars by their comparatively much rarer and more unexpected = occurrence, by the terrifying phenomena often accompanying them, and by the fact that they are seldom observed by others than ignorant people. The mode of studying the orbits of the meteor- ites must, therefore, be different from that suited to the case of the shooting-stars. Having made a special study of the dates of the recorded falls of meteorites, I have come to the conclusion that they, or at least some of them, may be referred to certain systems like the shooting-stars, and that in some cases periods—suggesting a connection with a certain group of comets—may be set down with some probability. The orbit of the earth around the sun may be considered as divided into three hundred aad sixty-five parts, one of which is traversed on each day of the year. That the fall of a meteorite occurs on a certain date means, then, that the part of the earth’s December, 1883, between eight and nine o’clock, as Mr. Lionzes, a book- seller in Fredrikstad, Norway, was standing in his yard looking inci- dentally up into the sky, he observed a shooting-star in the north, at æ height of about 60°, moving in a curve and gradually increasing a little in size. The exact length of time he is unable to state: he had turned his eyes away, when suddenly a small, shining body fell down before his feet, not two yards off, passing him so closely that in his fright be sprang aside. When the meteor struck the ground sparks flew in all directions, and a faint report was heard. This noise was also heard by his daughter, who at the time was in the passage leading to the yard. Shortly after— about a minute’—both father and daughter observed & similar meteor in the same direction, which seemed to descend behind a neighboring house. “The gentleman mentioned is uncertain as to the exact date of the observation ; but the choice seems to lie between the Saturdays, Novem- ber 3d, November 23d, and December Ist; but as, according to the meteorological observations recorded at the Fredrikstad Station, the sky was overcast on the two former Saturdays, the fall must have taken place on December Ist, when the weather was rather clear. He has stated to me that the size of the shining body was comparable to that of a walnut, and the little fragments into which it was broken when strik- ing the ground he compared to small beads. Unfortunately, he omit to collect them, and later search was unavailing, as the yard had beer swept several times afterwards.”’ On Meteorites. 107 orbit designated by this date is intersected by the orbit of the meteorite. It now often happens that the earth is struck by meteorites on the same date during two or several consecutive years. This can only be explained by the earth on that date passing through a swarm of meteorites, or, rather, through a long stream taking several years in passing—if we consider that, on an average, no more than four falls of meteorites are recorded yearly. Thus, the earth was hit four times by meteorites on the 13th of December, between the years 1795 and 1813.! Since then the earth has not collided with any meteorites on that date. Still more remarkable than dates which, like the above, show the meteorites to go in flocks, are others from which, with a con- siderable degree of probability, we may infer a certain period. Thus, the 13th of October is a date worth mentioning, as on that day falls of meteorites occurred in 1787, 1819, 1838, 1852 and 1872. On examining the differences between these years, they will be found to be very nearly multiples of 6}—viz.: 5x6}, 3x6} and 2x6}. These falls, consequently, seem to belong to the same flock, with a period of between six and seven years. The flock must be rather lengthened and takes a considerable time to pass, since the earth passes it so often, as is recorded in this case. If the stream be short, there is, of course, very little change of the earth being just in the point in which the orbits of the earth and the meteorites cross eac other every time the stream is passing. This would only be the case if the period were exactly one or more whole years. As this, of course, occurs but very seldom, it is not to be expected that the differences between the years be exactly multiples of the periods. It may be well to quote other similar periods of meteorites. In February, two series of falls are particularly notable, viz. :— February 19, 1785, at Witmess, February 19, 1796, at Tasquinha. n 18, 1815, at Duralla. ef 18, 1824, at Irkutsk. = 16, 1876, at Indesgherry. a 16, 1883, at Alfianella. The possibility here suggests itself that the earth on February 19, 1785, met a flock of meteorites which, with a period of about thirty years, reappeared in 1815. No fall is on record from the next meeting. From the one then to follow, however—that is, from the one to take place sixty-one years from 1815—viz., in 1876, a fall is recorded. It will be observed that the dates are receding, ‘To these falls may be added a fifth, which occurred on the Western Hemisphere, December 14, 1807. 108 On Meteorites. as the first fell on the 19th; the second, on the 18th. The third fall, if it took place, probably occurred on the 17th; while the fourth happened on the 16th. This regular receding of the dates may be explained without difficulty as due to the precession retro- grading comparatively fast.

Suppose the period being only one-half as long as indicated above, still another date might be added—viz.: May 18, 1860, on which day a fall occurred at London. In the following system, which has a period of about twenty- three years, the dates are receding :— y (23 i 4—Cirencester 1835_, H “9 Pawlowka 1882 As a result, then, several flocks of meteorites can be pointed out, which have a certain period, the latter being, in most cases, between six and eight years. It is noteworthy, in this connection, that the 110 On Meteorites. period of most of the comets, the return of which have been ob- served, is five or six years. The study of the dates of the different falls, therefore, not only suggests that at least a part of the meteor- ites move in orbits round the sun, but also intimates a certain rela- tion of some of them with a definite group of celestial bodies—viz. : the comets of short periods. We have thus established a new link connecting the meteorites with the comets in addition to those already known—viz.: the strong resemblance of the fire-balls to the shooting-stars, as well as the great velocity of several of the former, making it probable that they move in orbits of the same lengthened form as the comets. If called upon to define the nature of a meteorite, briefly and somewhat boldly, I should say, with Mr. Newton, the American: A meteorite is a bit of a comet. Let me add a few remarks in regard to the question whether there is anything in the structure of the meteorites which goes to confirm the views here set forth. The orbits of the meteorites being similar to those of the comets, the consequence would be, as mentioned above, that during a comparatively short time, once in each period, when near the sun, they would be exposed to an enormous heat, succeeded by quite as enormous a cooling off in the cold parts of space. The fragmentary (chondrite) structure, so general in the stony meteorites, is perhaps to be explained in this way. On the earth the annual and daily heating and cooling produces, as we all well know, the weathering or general crumbling of the earth’s crust, the formation of stones, gravel, sand and dust. There is a difference in regard to the meteorites, in so far as they are not covered with water or surrounded by an atmosphere, by which agencies the weathering of our earth is brought about; but, on the other. hand, the difference between the heat and the cold, owing to this very want, and especially to the form of the orbit, must be enormously greater on the meteorites ; for while the differences of temperature on the earth rarely rise to 50° C., the changes which take place on the meteorites must be estimated at 1,000° C., or more. It may not, then, be unreasonably supposed that the fragmentary struc- ture so common in the stony meteorites is due to the changes of temperature they have undergone. How the fragments may have become rounded off by being ground against each other or m some other way, may easily be conceived, as there are plenty of instances in regard to comets, in which movements in their mass have been observed. Theoretically, the study of the Tysnæs mete- On Meteorites. 111 -orite is interesting, not only for the fact that it clearly shows the chondrite structure to be of a fragmentary nature, but especially because it affords proof of the process having been repeated—a cir- cumstance not at all surprising in a celestial body which, in its wanderings through space, has repeatedly approached close to the sun. In addition to the above, it should also be remembered that the gases—carbonie acid, carbonic oxide and hydrogen—which have been successfully extracted from meteorites, are said to give the same spectroscopical lines as the comets when approaching the sun. The above explanation of the different peculiarities in the struc- ture of the meteorites is advanced here, of course, chiefly to instigate further investigation. As here propounded, it does away with all moments which may not be reasonably admitted in regard to the orbits of these celestial bodies, thus, for instance, making unnéces- sary any recourse to volcanic or other processes supposed to have taken place on distant globes once large, but long since exploded. In support of this latter theory—viz.: that the meteorites have originally belonged to globes of considerable dimensions—it has been argued that the formation of so large crystals as are found in some iron meteorites can only have taken place on a celestial body of respectable size. The correctness of this inference may well be doubted. It is true that on our earth—which, in this connection, may be regarded a big globe—some minerals form large crystals during a slow growth ; but it cannot be inferred from this fact that large crystals cannot appear on a very small one. The mere circum- stance that in the latter the force of gravity is practically nil makes matters there stand quite differently from what they are on a great celestial body. It may be supposed that as the force of gravity plays only an insignificant part, those other forces which produce the arrangement of the molecules in the crystals are allowed to have their play much more freely than under other circumstances. The smallness of the meteoric masses may perhaps also account for their — easy crumbling and the dislocation of the fragments. The minerals of the meteorites, which on our globe appear to belong to the com- paratively heavy substances, may in a certain sense be said to weigh nothing as long as they form part of a celestial body perhaps not a yard in diameter. Among other things, it may also be supposed that the electric — forces called into activity by the violent changes of temperature 112 On Meteorites. play a much greater rôle than we might be apt to imagine, judging from the processes which take place on our earth. Finally, I may mention that in some meteorites there is found evidence of their having been exposed to an enormous heat after their original formation. Several meteorites—particularly one from Steelldal, Sweden, which I have examined myself—show traces of an inner melting which must have taken place somewhere in space before entering our atmosphere, and which has nothing to do with the ignition of their surface in the latter and the molten crust — > ——— i bal f Fig. 5.

The black parts are iron; the light ones are pieces of unmolten substance swimming in a brownish glass, the chemical composition of which is like that of the unmolten substance. It will thus be seen that in the structure of some meteorites we have.a direct proof of their orbits being of the same striking form as those of the comets, which alternately approach close to the sun and then again recede far from it. at eee eae sp ey ee Eee ee P aa oy) ss Germ of the Southern Caitle Plague. 113 THE GERM OF THE SOUTHERN CATTLE PLAGUE. BY FRANK P. BILLINGS.) 17 order to prove that it is the manure of infected cattle which lodges the germs of Southern Cattle Plague, we must first find the germs. Has anybody found them? To which I answer that there has, and that the honor belongs entirely to Nebraska, as well as does that of completely connecting the germ of swine plague with that disease, and discovering the true nature of that pest. Detmers saw the germ of swine plague first, but it was left to us to prove its unquestioned connection with that disease. Our discovery of the germ was as original as if it had never been discovered, but in no way detracts from Dr. Detmers credit as the first discoverer. Detmers found a germ in the Southern Cattle Plague, but it was a large baccillus, and had no direct connection with the disease. Salmon found another coccus in this disease, also, but it was a double coccus, and had no relation to it. These observations will be considered in detail in our full report. How may we know that we have discovered the germ in any specific disease? In order to _ Make such an assertion the following conditions must be fulfilled in every detail :— First.—In the tissues of animals ill with a specific disease must, in each case examined, be found the same germ. Second.—This germ must be cultivated, free from every other germ, in some of the artificial media. i Third.—It must be shown that the germ in question has patho- genetic (disease-producing) qualities, by inoculating animals and killing them thereby. These three conditions have been fulfilled. The germ of South- ern Cattle Plague has been found in the blood, the gall, the urine, the liver, spleen and.kidneys of every diseased animal on which we have made an autopsy. These germs haye been also cul- 1! Director of the Patho-Biological Laboratory of the State University of Nebraska. 114 Germ of the Southern Cattle Plague. tivated in an absolutely pure form upon and in artificial media. Gophers, or ground squirrels, have been inoculated with such culti- vations and died from the effects, and the same germ found in their blood and tissues, and in sections made from their organs, Culti- vations from the same have been also made, invariably showing the same germ as that got from the cattle. These results, however, do not show that this was the germ of Southern Cattle Plague. They only show that a germ was found in the tissues of Texas fever diseased animals that had fatal disease- producing properties. ow, then, can we tell that it is the specific germ of the South- ern Cattle Plague? To be able to affirm this fact positively cattle must be inoculated, as the ground squirrels were, with unquestionably pure cultivations, and the Southern Cattle Plague produced in those cattle, and the same germ found in their tissues and cultivated from them. We have done this, and can demonstrate the entire series-of facts by cul- tures and microscopic specimens of the tissues.! 1Above I have stated the conditions which must be fulfilled in order to completely substantiate the discovery of a specific germ. I wish, however, to call attention to the discovery of another patho- genetic organism in which th diti tatp t be fulfilled and may never be so conclusively as we are enabled to do with germs of animal diseases. I allude to the germ of Yellow Fever, for which I claim not only the first discovery by an American, but for the only exact description of it. Babes saw it and partially described it, “ Les Bacteries-Babes-Cornil,”’ 1885, as follows :— ‘ The capillaries of. the liver and kidneys contain great numbers of jointed filaments. With a Zeiss yẹ H. I., one sees these filaments to be made up of elliptoid-cylindrical granule united in pairs, or forming small clusters, in which they are united by a pale intermediate substance. The filaments are thus made up of diplococci or of very short segments,” p. 448. In the“ Comptes Rendus,” Aug. 1887, p. 289, Lacerda attempts to describe an organism which he says is the same as that described by Babes, but his description is such a lamentable failure that no one would recognize the germ from it. In pieces of liver and kidneys from a ¢as¢ of ‘‘ Undoubted Yellow Fever,” sent me by Dr. Geo. M. Sternberg, ! discovered the same organism described by Babes, and, no other being present, and the yellow fever a specific septicemia, and this organis™ belonging to the same group, I make no hesitancy in affirming that it is the germ of the yellow fever, even though unable to fulfill all the 2 necessary postulates of exact experimentation. On the other hand, thé description of the germs of the Southern Cattle Plague and Swine Plague belonging to the same group, and an accurate knowledge of a several others belonging to this species, warrants the assertion that tbis { Germ of the Southern Cattle Plague. 115 o o om 7 rs o yi @ @ es 2 3, & o oOo O i <=> e TEE e > Cukpacrantsrici OF THE GERMS OF THE SOUTHERN CATTLE PLAGUE AND THE AMERICAN SWINE PLAGUE AND THEIR Pornts OF DIFFERENTIATION.' These two micro-organisms are neither to. be classed with Micrococci or Bacilli. They are not round objects like the for- mer or rods like the latter. They belong to the intermediate group, to which the name “ bacteria” has been given. Their longi- tudinal dimensions are about twice that of their transverse. They are ovoid. Their ends are rounded. If an endeavor be made to dif- ferentiate these germs from one another by a microscopic examina- tion we shall find it impossible. They are approximately of the same size and shape. Fresh specimens of them both will not differ so much in dimensions as old cultures of either will from fresh ones, or different individuals iu the same old cultures. They are description will answer in nearly every particular and every chief essential. The only points where a difference may be found will be these :— 1. The yellow-fever germ may cause gelatine to become fluid but pro- bably not as no other of these germs does. 2. It may grow differently on potatoes and egg albumen. In this regard attention will be called to the difference between the. germs of the Southern Cattle Plague and Swine Plague when developed on potatoes. Now I have still another and hitherto unknown germ of this same group of which more will be heard later on. On potatoes, the Swine-Plague germ grows a light gray-brown, coffee- colored; the Cattle-Plague germ in yellow colonies becoming reddish, this new germ pure white. On whites of eggs, the Swine-Plague germ grows in a semi-fluid almost pure white colony, difficult to see. The Cattle-Plague germ develops in a delicate buff color with sharply circumscribed walls, while the new organism grows in deep yellow colonies with diffuse edges. However, I feel that aside from these points, the description herein given will answer completely for the germ of the yellow fever. Morphologically it cannot be distinguished surely from either of them 1 With the exception of the points to which attention has been called _ as to the germ of Yellow Fever. 116 Germ of the Southern Cattle Plaque. about 4 the transverse diameter of a red-blood cell, in length. In one way, however, they can be easily differentiated even by micro- scopic examination. The swine-plague germ has a far sharper afin- ity (its poles) for the blue and violetHinctions than that of the Southern Cattle Plague, while the tatter pussesses a special affinity for Fuchsin, which the former does not. Whatever the tinction used, if applied lege artis, the ends, poles, of these micro-organisms show a great specific affinity for the coloring material, while the middle portion of their bodies has far less, unless the exposure is pushed to a longer period, when this portion of the body will eventually color. The capsule of these germs seems to be composed of the same material as the ends, as it also colors in the same manner, thus presenting a delicate line of colored material, connecting the two colored, coc- coid ends, or poles. The most practical illustration which can be given of the micro- scopic appearance of these organisms, is to take a small white bean and paint both of its ends and two of its sides blue or red, leaving the middle portion unpainted. Looking down upon such a bean would give almost an exact picture of these germs. Like the genuine and only germ of the American Swine Plague the micro-organism of the Southern Cattle Plague is motile in fluid cultivating media when studied microscopically, as well as in the serum from the blood of diseased animals. The movements of the latter are, however, less rapid or active than those of the former organism. In my earlier description of the micro-organism of the American Swine Plague, I called attention to the great morphological varia- tions which it undergoes in its full cycle of development. These are its morpho-vegetative phenomena. To one entirely unaccustomed to observing them, the first appear- ance of a cultivation of these germs—more especially an old one— would prove very puzzling. In fact, the novice would very often conclude that his cultures had become polluted by micrococci, so plentifully are these objects, apparently, represented. They simply represent a vegetative, embryonic, period in the development of this class of micro-organisms. 1For some, to me, unaccountable reason the German observers say the germ of the German Swine-Plague isnot motile and Cornil says the same thing. Now I positively assert the micro-organism of these two American diseases to be motile as well as a third one which I am not yet ready to describe. Germ of the Southern Cattle Plague. 117 Hueppe has fallen into the serious error of endeavoring to clas- sify these organisms by this vegetative morpho-condition. He calls them “ Micrococci.” To my mind it would be equally sensi- ble and logical to call an ovum a man, or an apple seed an apple tree. It is far more practical for patho-biologists to stick to the name cocci for all round objects (not spores) which have equal diameters in their mature form and which color diffusely, and to call these ovoid organisms bacteria, where the longitudinal diam- eter does not more than over again exceed the transverse. As to bacilli, spirilli, etc., there need be no dispute, so plain are their morpho-characteristics. The mature micro-organisms of the American Swine Plague and Southern Cattle Plague has been described above (Fig. 1) as resembling a white bean with the ends painted as well as its sides, leaving the middle portion of its body unpainted, as we look down upon it.. Now that is the picture which the eye generally receives, but a more exact inspection of a stained covering glass specimen will show that the above is not always the appearance presented to the eye, even by the mature germ. The above description depends upon the germ presenting itself to the eye in an exact horizontal position, that is, lying straight on its horizontal axis. If, however, it be turned a little one way or the other on its horizontal axis, numerous specimens will be seen where the white belt does not extend entirely across the object, as above — described, but seems to be limited, more or less, to one side, and more of the colored substance will be seen un the opposite side than under general circumstances, or, perhaps better, in exact inspection (Fig. 14). At first I mistook the appearance for the accumulation of the uncolored substance in this way during the process of its secretion from the colored ends, which I take to be the method by which this non-coloring material is produced. More mature reflection has shown me that the above explanation is partially or wholly incorrect. It has been mentioned that that portion of the capsule of these micro-organisms must have the same chemi- cal composition as the pole ends, because it also colors somewhat under the same application of the tinction. Now why does it not show the same intensity of coloring? The only answer is: that this capsule, being very thin, cannot take wp as much color as the more dense pole ends; and being so thin, by the same amount of exposure, does not show any color when the middle of the object is looked directly 118 Germ of the Southern Cattle Plague. down upon, but when the eye- strikes the sides of the object, then we look through more material and, hence, see more color, just as when we look at a piece of window glass or a good glass slide. If we look directly through it, it is colorless, but if we turn it on edge and look at it, it has a more or less green shade, according to the quality of the glass. So according to the amount of exposure to the tinction, when not carried so far as to color the whole body of the germ, we have more or less visible coloring of the capsule, which can only be seen when we look through a considerable extent of substance, that is, on the sides of the object. Again, we may see two or three objects united together, all presenting the normal char- acteristics of full maturity. I have never yet seen more than three of these germs connected together (Fig. 2). In general they either appear singly or in pairs. In very old cultures these micro-organ- isms become thinner, more rod-like, and color more diffusely with the same degree of exposure to the tinction, and the white substance is either not visible at all or very faint (Fig. 3). Again, such old cultures are very replete in apparent micrococci, of various dimen- sions, which might lead one into the error of thinking that his cul- tures had become polluted. I call this last condition that of coccoid degeneration (Fig. 3). Or, we may see unusually long objects, the longitudinal diameter being twice or three times that of the mature organism, and the white, or uncolored, substance occupying a cor- responding extensive amount of space, while the dark, or colored, ends may be somewhat larger or of the same size as those of the mature object. This condition represents the first step in the develop- ment of these organisms, that is, they become longer, and more of this white substance appears (Fig. 4). The next step in the process of vegetative development is the _ separation of one of the pole or coccoid ends, which then becomes free, and for a moment is exactly round like a coccus, and, as in a hanging drop culture (to which I always add a very small amount of an aqueous coloring solution), one will naturally see a very large number of these coccoid objects on account of the fact that each individual present is continually going through the same process 0: multiplication. Here, again, one may see a condition or phenome- non that might be misleading. One of the coccoid ends having been separated, the other may still remain connected with the white material, and as evidence that the colored ends have a greater degree of specific gravity, as well Germ of the Southern Cattle Plague. 119 as chemical composition, you will see, in the continual tumbling about, and turning over and over of their objects, a white, round or nearly so, colorless object directly under the eye, or numbers of these objects. When the germs in such a hanging drop culture have died from want of a sufficiency of nutrient material, you may see a large number of these objects, which could be easily mistaken for spores: but if we inoculate a new hanging drop culture from the same material used to prepare the former, it will be found impos- sible to fall into any such serious error, for it will be easily seen that these non-colored refracting points keep continually going out of sight, their place being taken by the coccoid non-refracting point still attached to the other end of the white substance, and by watch- ing one and the same organism in its continual turning over, first one appearance and then the other will be presented to the eye until the second coccoid end has become detached (Fig. 5).! What becomes of the uncolored transparent middle piece? I do not know! It appears, however, as if it underwent an almost immediate pro- cess of dissolution the moment it has become free from both of its polar attachments. That this substance does not represent a spore condition, or have any relation to spores, is to my mind entirely beyond all question, as I have searched most diligently for spores in old and fresh cultures, and others made at all kinds of tempera- tures, within the biological limits of these organisms. In my first-published description of the micro-organism of the swine plague I gave an erroneous description of the manner in Which the coccoid ends became freed from the white or connective substance, This white, non-refracting, wncolorable material does not become extended to nothing, and then break in two, leaving the coccoid ends with a delicate, colorless flagellum, or spermatozoid tail, tempo- rarily attached to one side, as I then said, and as Detmers described it in 1880; but the separation of these ends is direct, and by sharp segmentation. Were it otherwise we could not see the sporoid colorless ends of so many of these germs when freed from their appropriate pole ends There are days when one cannot study them continuously at all. The best way to study hanging drop cultures, when one desires to spend several hours over them, is to first make some cover-glass Pati. such a specimen will at once show that no spores are pre- sent. i 120 Germ of the Southern Cattle Plague. specimens of the same material, or take any other slides of an object of the same size and form, and observe such for about half an hour, thus preparing the eye to see what you want to see in the liv- ing developing organism. Unless this is done, some very essential points will be surely missed, and some preventable error fallen into. With anything less than a power of 800 diameters no one should attempt to study these organisms, and then only when aided by the best of Abbe condensers and oil immersion lenses. We left our studies with the mature object proliferated into its first distinct stage of vegetative di erentiation. We had two coc- coid objects before us, that is, two round objects, their diameters being the same in any direction. If colored, they color throughout, that is, diffusely. Were these objects to remain in this condition, they would be, indeed, Micrococct. They do not, however. They almost imme- diately begin to increase in a longitudinal direction, but in this con- dition they still stain diffusely. In my first description of the swine-plague germ, I said that the next biological phenomenon was the appearance of a delicate white line, separating this ovoid object into two halves. The above, while not exactly an erroneous description, is certainly anticipated by another phenomenon in the evolutional development of this coccoid, - diffusely coloring object, into the mature form of any of this class - of germs. That this white non-coloring substance is a secretion of the two poles, or coccoid ends, of these “ belted” germs, as well as that it has a different chemical composition, is beyond all question. The phenomenon above spoken of, as anticipating the formation of the segmenting white line which separates the two darker por- tions of these organisms is: that this white substance first appears in the centre of the body of the dense, dark ovoid object as the minutest of white specks, which gradually increases in size and quantity, and extends across the entire object ; the white line, being at first broader in the middle, but gradually widening until it completely and clearly separates the two pole (coccoid) ends, and the mature object is again presented to our view (Fig. 6). We have thus described the normal, or general, cycle of devel- opment of the micro-etiological organism of the American, English and German Swine Plagues, the American Southern Cattle Plague, Hen Cholera, the German “ Wild-Seuche” (of deer, swine and cat- tle) and Rabbit Septicemia, all of which diseases are caused by a Germ of the Southern Cattle Plague. 121 member of this class of “ belted” germs, and should be classed as extra-organismal, local or land septicemie. It seems to me that the germ of Yellow Fever, as well as the disease itself, should also come into this group.' I am sorry to say that, notwithstanding the results claimed by Freire, I am unable to find a single exact and detailed description of the germ with which he works, and which should therefore be the etiological moment in the Yellow Fever, if there is any trustworthiness in Friere’s statements. MorPHO-BIOLOGICAL RESEMBLANCES NOT SUFFICIENT TO PRo- NOUNCE PATHOGENETIC GERMS OR DISEASES CAUSED BY THEM IDENTICAL. This part of my work would be left incomplete did not I allude to an endeavor of Hueppe’s to show that the diseases named above, aside from the Swine and Southern Cattle Plague of this country, are identical, that is, the German, Schweine-Seuche, Hiihne-Cholera, Kaninchen Septikamie und Wild Seuché must all be one and the same disease; because their germs have each and all the same form, the same size, the same “ belted” appearance, and because they all grow alike in bouillon, on agar agar and in gelatine. The Germans do not say anything as to how these germs deport themselves on potatoes. The Schiitz-Loeffle germ does grow on pota- toes, as Professor Kitt, of Munich, assures me. No greater or more misleading statement could be made, or per- haps it would be better to say principle or theory enunciated. The most complete morphological resemblances and exact mor- pho-biological relationship in or on artificial media are not suffi- cient grounds for any such attempt at generalization as Hueppe’s in the case of these diseases. To all beginners in this work, and all older hands as well, I most emphatically assert that there is but one factor in the biology or morphology of etiological micro-organism which can decide whether _ two germs apparently alike are one and the same object, when de- rived from two distinct diseases of animal life. That factor is a physio-chemico-biological one. Both germs must produce the same disease in both species of animals: the same chemi- cal and pathological phenomena which ocerr in the same diseases and eloa E eo stated by researches subsequent to the prepara- * Colin says the same. 122 Germ of the Southern Cattle Plague. in the same species of animals under natural conditions, when healthy animals of the given species are inoculated with artificial cultivations of the germs in question. Our experiences here completely upset Hueppe’s hypothesis. The American Swine and Southern Cattle Plague should, accord ing to Hueppe, be identical diseases with those mentioned as con- sidered so by him in Germany, because, according to his condition, the germs are identical, Hueppe’s entire argument is completely nullified by the following facts :— First.— There is no Southern Cattle Plague known in Europe. Second.— Cattle and Swine run together in this country, and one or the other may have respectively Swine or Cattle Plague, and yet the other species will never become ill, even from the closest contact with members of the other species sick with its peculiar plague. Hens can feed on hogs dead from the swine plague, from the ground polluted with their discharges, even picking out grain from the same, and still remain wel¥; and the same is true of the hogs with regard to Hen Cholera and the Southern Cattle Plague. Hence, no matter how these germs may resemble each other, when artificially examined, they fail in the one great factor necessary to make the diseases produced by them identical; they do not have the same physiological chemical attribute with regard to a given something produced, which invariably decides the pathogenetic results produced by a given germ. Notwithstanding the latter fact, these diseases all have a very close relation to one another. They are all extra organismal, local land septicemia. Each one, however, has something peculiar about them that prevents them from being identical diseases, aside from any action of the germ. Each species of animal in which they occur has some unknown constitutional idiosynerasy which renders its members susceptible to the action of a given germ, and each of these germs has some peculiar unknown biological idiosynerasy by which alone it infects, naturally, but a given species of animal life. These two factors, together, can alone decide the identical ques- tion. What we can do artificially, by the inoculation of those ani- mals that the disease does not occur in naturally, has no necessary relation to the question whatever. There are, however, other phases in the development of these germs of a bio-morphological character. For instance, as already said, we may see two or three individuals of the mature type united Ph ee eee ee Germ of the Southern Cattle Plague. 123 together (Fig. 2), or we may find two apparently mature organisms enclosed in a common capsule, the two medial dark points or poles being in such close apposition that no line of demarcation or inden- tation of the capsule can be seen at this point, the whole outer sur- face being smooth (Fig. 7). On the other hand, the two lateral ends, or free poles, are separated by the normal quantity of white, non-colorable substance. Again, these diplo-bacteria may assume a curved or sausage shape, which we may sometimes see intimated in the single organism, ma- ture (Fig. 8). At other times, though not very frequently, the germ may appear in nearly its normal form, but one pole (coccoid) end will be semisegmented from its appositional end of the white substance by a constriction of the same at its line of attachment with the pole end (Fig. 9). This end will then be smaller than the opposite pole, thus giving a sort of pear shape to the entire organ- ism: the small pole end is soon dropped, however, and becomes momentarily a free coccoid, and goes through the cycle of morpho- development already described; the same occurs with the other pole end. This concludes my observations of the micro-morpho-biological phases presented by these two micro-etiological organisms in the course of their development. There may be some minor phenom- ena that have escaped my attention, but I am very sure I have de- scribed all the essential points. THE SWINE PLAGUE AND SOUTHERN CATTLE PLAGUE GERMS DIFFERENTIATE THEMSELVES VERY SHARPLY BY THEIR APPEARANCE WHEN CULTIVATED ON POTATOES. If we properly prepare (see text-books) and sterilize some nice, clean potatoes, and then place them (lege artis) in a sterilized, moist, cultivating chamber, and inoculate the cut surface of some of the potatoes from Agar Agar, Boullion or other cultivations of the microdrganisms of these two diseases, we shall invariably find that they can be readily differentiated from one another in the course of from twenty-four to forty-eight hours after the surface of the pota- toes has been inoculated. The growth of the germs of the American Swine Plague will invariably present a peculiar brownish-yellow to the eye, reminding one of coffee color, especially the sion one gets in the ordinary boarding-house and restaurant.' 1 Colin says “‘ greyish.” 124 Germ of the Southern Cattle Plague. On the other hand, the micro-etiological moment of the Southern Cattle Plague will with equal constancy present a growth of the most delicate straw color during the first day or so of its development, but which soon begins to show a delicate pinkish, red-yellow, and finally quite a decided brick-red-yellow shade, as the cultivation becomes anti- quated ; this reddish shade begins and grows most intense at the centre of the growth, leaving it more yellow toward its peripheries. THE DEPORTMENT OF THE GERMS OF SWINE PLAGUE AND SOUTHERN CATTLE PLAGUE IN BEEF-INFUSION GELATINE. As what is known to us as beef-infusion gelatine cannot be used in hot weather, or when the prevailing temperature is above 75° F. (23° C.), on account of its becoming fluid, I could not use this material until the last moment, and only prepared the first of the season on Saturday last, October 1, and on Sunday was enabled to inoculate tubes of this material with from pure cultivations of the germs of Southern Cattle Plague and hog cholera. This beef-infu- sion gelatine is an invaluable medium in the technique of bacteri- ology, for two essential reasons: First, being transparent, one can see what is going on on it, and, secondly, many micro-organisms cause the solid material to become fluid, and present peculiar phe- nomena to the eye, while others do not cause any change in it, but may grow in a peculiar manner. Now the hog-cholera germs belong to the latter class,as well as the germ of the German, French and English swine plagues, which are probably identical with hog cholera,as also those of hen cholera, and the peculiar disease known as “ wild Seuche” in Germany,which affects the deer tribe and cattle and hogs, and belongs to the same blood- poisoning group as hog cholera. When we take our hog-cholera germ,and inoculate tubes containing this beef-infusion gelatine from the pure agar agar cultures, we shall observe that the germs do not cause the gelatine to become fluid, and that it never becomes so, 80 far as any influence of the hog-cholera germs goes, if the culture from which the material has been taken was a pure one, that 1% contained no other form of micro-organismal life than the germs <4 of hog cholera. This germ, however, has other peculiarities; it slowly spreads 1 The germ of the English Swine Plague was first discovered by a : in 1886, in some tissues from England belonging to my then assistant, = Dr. Bowhill, M.R.C.V.S. = PP, a ee ee mre em mne aL AP Mats ee ya HS ey Mf is SEI ee eee ee ee x j Germ of the Southern Cattle Plague. 125 over the surface of the gelatine as a delicate cuticle, but, as these cultures are made by puncturing the gelatine with a wire, the germs are carried into that substance by the wire. Here we observed that everywhere the wire has left a germ in its passage through the gel- atine, that a small colony develops, giving to the puncture the ap- pearance of a delicate thread with knots along its course. In the end these colonies unite, and give the puncture a ragged-edged ap- pearance. As the germs of the German swine plague, and rabbit- septiceemia, and the “ wild Seuche” all do the same thing, Hueppe asserts them to be the same organism. Hueppe has tried to claim that all these diseases were one and the same, a mistaken view, as I have tried to show. I have now to chronicle the first serious error, a genuine mistake of carelessness, from undue haste, that I can charge myself with during my investigations of the two micro-etiological organisms here considered. Above it was said that on October 2d two beef-infusion gelatine tubes were inoculated from pure cultivations of the germ of the Southern Cattle Plague, and in the local papers the following remarks were published : “ Now it became interesting to see how this Southern Cattle- Plague germ would deport itse!f in this gelatine, because it cannot be distinguished from that of hog cholera under the microscope, or on agar agar, or in bouillon. That it can be by its growth on potatoes has been already noted. Hence, on Sunday, October 2d, gelatine tubes were inoculated. You can judge of my surprise on seeing that this Cattle-Plague germ could be at once distinguished from those of hog cholera standing beside it. The germ of the former had caused the gelatine to become fluid to the bottom of the puncture in twenty-four hours, which is quite rapid work.” The above was scarcely in the hands of the readers of the two journals before I began to have grave doubts of the correctness of my observations, simply because all other known germs belonging to this “belted” group, and the cause of extra organismal septicemia, do not cause the gelatine to become fluid. In order that others may profit by an error which is unpardon- able on my part, I will briefly tell how it came about. At the time I had just twenty agar agar cultivations of the germs of the Southern Cattle Plague, which I looked upon as pure, and which represented the outbreak at Tekamah and Roca, my inoculated 126 Germ of the Southern Cattle Plague. steer, and material from a ground squirrel. In making the gelatine tube, I simply inoculated from one agar agar tube on two gelatine tubes, with no other precaution than a macroscopic comparison of the growth with those in the other agar agar tubes. I could see no change in the appearance of the growth of the tubes I used. J should have made, and every one should always make a few cover-glass specimens for the microscopic test in all such eases. (In the case of these germs, it would be futile, however.) After the cultures in the gelatine had become fluid, I then inoculated the entire agar cul- tivations (twenty) upon gelatine, and carefully numbered each tube with a corresponding number, so as to control the number. This time I was not at all surprised where in nineteen of the beef- infusion gelatine tubes no fluidification had taken place, the same occurring in the one as before and from the same agar tube. It is now February 6th, and the tubes remain exactly as they were on the 8th of October. Hence, the germs of the Southern Cattle Plague, like those of the American Swine Plague, and other diseases of the same group, that are caused by the belted oval germs do not cause fluidification of gelatine media. I next inoculated twenty pieces of sterilized potatoes (and for comparison’s sake twenty others from cultivations of the Swine- Plague germ), and here I found no change in the appearance of the growths from those previously described. From the twenty potatoe culture of the Southern Cattle Plague germ I again inoculated twenty gelatine tubes. Nineteen remained solid ; one became fluid. As the potato culture from the tubes which caused the gelatine t0 become fluid did not show any variation in the color of the gro upon agar agar from the others, I resorted to plate cultivations a5 well as the microscope to solve the riddle. : This one tube contained a small number of the most contempt- ibly small micrococci, yet enough to have got me into a serious error. They required 2,000-diameter amplification to see them distinctly, and, as I have said, Micrococci constitute a normal mor- — phos in the development of this class of germs, their presence would have excited no suspicions had I subjected the original cul- ture to a microscopic examination. Still it should be done in eve f case, so as to keep up a good rule. a They were separated with ease on plates. Inoculation up — Gophers with the mixed culture gave fatal results, but no coc? — Germ of the Southern Cattle Plague. 127 could be found in their blood or tissues, nor did any develop in tubes inoculated from them. Inoculation upon Gophers and mice with pure cultivations of the troublesome cocci gave absolutely neg- ative results, no disturbance except a little stiffness and swelling of the limb occurring. The reason that the color of the agar agar, and especially pota- to cultures of the Swine Cholera-Plague germ was not affected by these cocci was that the former are so much larger and grow so much faster as not to be much affected thereby on that medium ; while in gelatine this whole group of germs finds a poor nutrient material, and grow very slowly; on the contrary, the small cocci grew exceedingly fast in the gelatine, and also caused its fluidifica- tion with greater rapidity than any pathogenetic organism with which I am acquainted, not excepting Finkler’s and the cheese “Comma.” Second, they are almost transparent, and have no chromogenic properties. That they had less specific gravity than the Southern Cattle- Plague germ could be determined by a microscopic examination of the material at the apex of the fluidification, by tipping the tubes gently; here the Southern Cattle Plagne organism greatly pre- dominated. A THE GROWTH OF THE GERMS OF SOUTHERN CATTLE PLAGUE IN Beer-Inrusion GELATINE AS COMPARED WITH THOSE OF THE AMERICAN SWINE PLAGUE. While neither of these micro-organisms cause fluidification of the beef-infusion gelatine, still there are certain minor points which have a degree of differentiating value for each of them. The germs of the Southern Cattle Plague have more desire for the air than those of the Swine Plague, they are more ærobic; while they spread slowly over the surface of the gelatine, still they do it more rapidly than the swine-plague organism. Along the line of punc- ture in the substance of the gelatine there is, however, no percep- tible difference in the deportment of the two germs. They each form individual colonies along the line, which gives to it an irregular jagged appearance, resembling the cutting edge of a saw. If anything, this surface is more dentoid in the Southern Cattle Plague cultures than the Swine Plague growths in beef-infusion gelatine, 128 Germ of the Southern Cattle Plague. This concludes my present observations upon the development of these etiological organisms in and on different cultivating media. Not having a refrigerator, I have not compared their developments. upon blood serum up to the present time. Now these facts of some of the biological (or life) characteristics of these two germs show that, while two germs may look alike and grow alike, even in every particular, they may have one other attribute which in such cases can only be relied upon to detect one from the other. That is their origin or, in other words, their disease-producing action. It needs no argument from me for the practical farmer to know that the Southern Cattle Plague will not produce hog cholera in his. hogs, or the latter disease the Southern Cattle Plague in his cattle. ON SOME INTERESTING DERIVATIONS OF MINERAL NAMES. BY F. M. ENDLICH. (Continued from January Number.) 3. In addition to those mineral names which have undergone curious changes in the course of timé, there are others which show interesting etymological relations, and yet have descended to us in but slightly changed form. KERMESITE is derived from the Sansk. krimi, worm; Pers., kirm or kirmis, scarlet; Ar., alkirmis; Sp., alkermes; G. obs. Kermes, the “scarlet bug,” cochineal insect. Chermes, the drug- gists’ name for the substance, reached Spain from Arabia and thence- travelled to Italy and Germany.! The Sansk. form krimi has been retained in our Engl. crimson. It is also recognizable in the Lithuanian kirminis, worm. In It., Fr. and, later, Sp., the letter a was substituted for ¿i and e, resulting in carminio and carmine: whence the mineral name Carminite. 1 ‘* Chermes vocant Arabes vnde nos chermesinum ; sev et vermilium vsurparunt quidam, a vermiculis exemptis a radice pimpinelle; coccum autem alio nomine dicitur scarlattum.”’ (Czesius, 1636.) Derivations of Mineral Names. 129 AzuRITE.—The immediate derivation of the word is from N. L. azurum, sky-blue. Originally it comes from the Pers. ladyuward, or lazuward. In M. H. G. the adjective lassuvar appears, which has survived in the H.G. under the form of Lasur and Kupferlasur, copper-blue. During the reign of Emperor Augustus, about 20 B.c., the L. word azulus—Lapis Lazuli—is met with. (M. Vitr. Pollio, the architect.) Early in the fourteenth century the N. L. asureus occurs, the initial / having disappeared in Latin. In the recent forms—It. azzuro, G. azur, Fr. azur, Engl. azwre—the original z takes the place of the N. L. s; but in O. Engl. the latter can be found :— “a broche of gold and assure, tn whi a aul set was like an herte.” —Chaucer, 1340-1400. In the sixteenth century, however, the word had assumed its present construction :—- - “that deckt the azure field.” — Spenser, 1552-1599. Lapis Lazuli owes its derivation to the same source, and, like the G. Lasur, has retained the initial 1. “ Azurri ultramarinum materia ex lapis lazuli” (Cesius, 1636), shows the Latinization of the It. wo Marcasite is derived from the Ar. markashitsa, pebble.’ The word was introduced in the thirteenth century, and was especially applied to minerals which showed bright, metal-like lustre (Kiese of the Germans). It was known to Alb. Magnus (1280) under the form of marehasita, and he characterized it asa mineral out of which no metal could be extracted by fire. Two kinds, mainly, were distinguished—the one yellow, shining like gold (pyrite, ete.: “ Pyrites sine dubio Arabib. marchasita est” [ Agricola, 1546]) ; the other, purer and more valuable, like silver (marcasita argeneta of the alchemists, bismuth)? One characteristic of the marcasites was 1 Personal communication from the Arabic scholar, Rev. Wm. Wacker- nagel, D.D. *“‘Marchasitarum species multe ac diuerse sunt, . . nam alia aurea ; alia argentea ; alia cuprea. ab igne non liquefit ; sed per se com- buritur. ” (Leonardus, 1610.) 130 Derivations of Mineral Names. that they nearly all contained “brimstone” (Cotgrave).! Accord- ing to Boyle (about 1670), “ Marchasitical stones” abound in those ‘portions of the earth where the temperature is excessively high. From various old writers, it would appear that the Arabic physician Avicenna (about 1020) had previously used the name. A rather fanciful derivation brings the word from the Ar. marv, kyass, idd— whitish, glistening flint (Kobell). 4, Among the mineral names there are some which have retained their original form with surprising regularity and have distributed it through many languages. JASPER descends from Heb. iashpheh, Ar. iasheb or iashef, Pers. iashm, Gr. edoztc, L. iaspis, M. H. G. jaspis, O. Fr. diaspre, Fr, iaspe, O. Engl. jaspe, jaspre, Engl. jasper, H. G. and Sw. jaspis. “ His stone is jaspe.” —Gower, about 1360. ‘ The floore of jasp and emeraud was dight.”’ —Spenser, 1552-1599. ’ laoneg is used by Plato (429 to 348 B.c.) and others after him; L. iaspis, by Virgil and Pliny, over eighteen hundred years ago. SAPPHIRE is derived from Heb. sappir, Ar. safir. In Gr. the ` two p’s of the Hebrew persisted, but the second was aspirated: cangepog. M. H. G. used the word saphir ; O. Engl. saphire:— “ Of rubies, saphires and of perles white.” —Chaucer, 1340-1400. In It. the word has become safiro, zafiro ; in Sp. zafir, Fr. saphir, Sw. safir. The H. G. and Engl. versions, however, retain the two p’s, as in the Greek. | The It. zafiro was perpetuated in obs. G. zaffer, used to designate blue cobalt-glass and blue colors; Engl. zaffre describes a purplish cobalt color. Sandexpos was used by Dionysios Periegetes about nineteen hun- dred years ago, apparently in connection with the gem which now carries the name. Pliny also describes “sapphires,” but evidently not the precious stone, as he states that it glitters with marks and specks of gold ; this would apply to Lapis Lazuli? Agricola (1546) 1 Gessner (1565) claims the following: “ Pyrites recentiores marcha- sitam vocant, nostri corrupto nomine martistein.” 2 “ Sapphirus enim et aureis punctis collucet.”’—Pliny, Venice edition. Derivations of Mineral Names. 131 uses the correct orthography, “sapphirus ;” as does Kentmann, in 1565. ARSENIC.—The origin of this word is Gr. 4657», or, as the second of two ¢’s frequently changes to a o, dgoyv=L. mas, strong, mas- culine. By transposition the word dvy¢—=man, is formed from app», the one p being dropped. Homer uses dv7yo, 880 B.C., and, after him, all other writers. In Sophocles, however (497 to 406 B.c.), we still find dooyy, in the sense of strong; also in Aristophanes (412 B.c.). “xruro¢g ao6ny zovtov” (noisy, powerful sea), Sophocles. Theophrast writes d/evexov, about 300 B. c.; Galenus (A. D., 181 to 202) employs àpøsv:xov, a poison. It is probabli that the older forms were used to designate a variety of strong poisons, min- eral or vegetable. Curiously enough, the form pey», without the lengthening ter- mination ¿xov, has survived in the G. Arsen, which signifies metal- lic arsenic. The Latinized form of àpøsvexov or dpaevexcov, which latter was used by Aristotle (384 to 322 B.c.), is arsenicum: whence G. Arsenik—i.e., arsenic oxide—O. Engl. arsenik (Pettus, 1683) and Engl. arsenic. Dramonp.—Derived from contr. Gr. a, privativum, and dapaw, I conquer=unconquerable. The name was originally given to hard steel and iron, and Hesiod uses it in this sense about 750 B.c, Since the days of Theophrast (about 300 B.c.) it has been applied to diamond. Gr., ddapac. The word enters Latin as adamas. “ Unde et nomen indomita quis Greca interpretationes accepit” (Pliny). Pliny claims that when laid upon an anvil and struck with a hammer, the adamas will cause the latter to recoil and will remain unharmed, if, indeed, it fail to burst either sledge or anvil: hence its name. Only by sprinkling upon it the blood of a male goat can it be reduced to such a condition that it will no longer withstand the heaviest blows.! In the middle of the sixteenth century the word was Dyamant in Germany; M. H. G., Diemant ; H. G., Demant and Diamant; It. and Sp., diamante ; Fr., diamant; O. Engl., diamaunt ; Engl., diamond. “ Haue harte as hard as diamaunt— Stedfast and naught pliaunt.”’ — Chaucer, 1340-1400. 1“ Adamantem opum gaudium wr abe Has omni caeteri et inunctum sanguine hircino rumpente queque.’’—Pliny, Venice edition, 1559. 132 Derivations of Mineral Names. The original form of Gr. ddapa¢ has been retained in the Engl. adjective adamantine=diamond-like, and in other words :— PE Se ate - ‘three folds were brass, Three iron, three of adamantine rock.” — Milton, 1660. Mace is the name of a mineral which, when broken across its principal axis, shows a white cross or rhomboid spot enclosed within a dark matrix. The word is derived from L. macula, spot. G. makel, blemish ; Engl. maculate, to spot, and immaculate, are from the same root, as is Fr. macule, spot. Macula is classical, and may have reached the Romans from Gr. pazxedov=inclusion, mark. Pierres de macle was applied to the mineral in 1751 by Robien. (Dana.) The meaning of Fr. macle is “ perforated rhomb”: whence its application to the mineral, which often shows such a figure on cross-section. CARBUNCLE.—Pliny uses the name carbunculus, a diminutive of carbo=coal, in allusion to the resemblance of the gem to a glowing coal. In G. the b has changed to an f—Karfunkel—but remains b in Sw. Karbunkel. It is a coincidence that the G. funkeln means glowing, scintillating. “ Curbunculi a similitudine ignium apellati.” (Pliny. While the Greeks had a totally different name for the mineral, it is interesting to note that the origin of both the L. and Gr. words refer to the same peculiarity—i.e., to some glowing light. The Gr. name is derived from Avyvevw==[ shine brightly, I light up. SMALTITE.— The Gothic form of smalyan, smalteis=melt, or smelt—was smalzian in M. H. G.; then smelzan (G. schmelzen); and these resulted in the M. L. smaltum=glass-flux. In the ninth century M. L. smaltum was used in the sense of smelted substance= enamel—in describing a “ crux pulcherrima gemmis et smaltis.” (Ana- stasius.) It. smalto and G. Smalte, as well as M. L. smaltwm, were finally applied to the blue cobalt glasses and cobalt colors, which be- came known about the middle of the sixteenth century. Since that time the word has retained its specific meaning. H. G. Smalte or Schmalte, Fr. smalt, Engl. smalts, Sw. smalts, all designate the color or substance known as cobalt-blue. STANNITE is derived from L. stannum, originally stagnum. It is probable that the word is of “Celtic origin; and the Irish stan, Welsh ystaen, may be regarded as direct descendants from the old root. Sueton and Pliny knew stannum as an alloy of tin and lead. Derivations of Mineral Names. 133 The old form of stagnum produced It. stagno; later, stagnuolo ; whence obs. G. Stagnol, H. G. Stanniol=tin-foil. From the same source are Sp. estano, O. Fr. estain, Fr. etain. In O. H. G., tin was zin; in A.-Sax., tin—possibly related to Sansk. tshina, lead; obs. G., Zien (1743); H. G., Zinn; Sw., tenn; D., ten; Engl., tin. The Engl. words stannary=tin-mines, and stannous, retain the Celtic (?) root. G. Zinn and Zink probably have a common origin, but the connection is obscure. A derivation from A.-Sax. tynan=to shut, close, fasten, hence solder, has been suggested for tin, but seems untenable. 5. There are a number of mineral names which derive special interest from their application. The peculiarities ascribed to Wolfram, Nickel and Cobalt are productions of the German miner, whose fertile imagination saw more than mere matter-of-fact cir- cumstances. Since the twelfth century mining has been prosecuted in Germany ; and it can readily be imagined with what strange creatures the superstitious workman of those early days might people the underground domains. WOLFRAMITE.—The word is of German origin, being a contrac- tion of O. H. G. wolfhraban. The latter is formed by a combina- tion of wolf, wolf, and hraban, raven. Among the ancient Germans, in fact, until the introduction of Christianity became general, the meeting with a wolf ora raven was considered a favorable . omen under nearly all circumstances; and the most. emphasized indication of coming good fortune consisted in meeting both of these animals. In the tin-mines of Germany and Bohemia, as well as in a number of silver-mines, the occurrence of Wolframite was an almost infallible index of the ee of good ore: hence the appli- cation of the name. Wolfhraban contracts into wolfhram [ Wolffhram, as late as 1565 (Fabricius)], and, by dropping the h, into Wolfen. Wolf was for many years a favorite baptismal name in Germany, and may be found to this day in some families of feudal descent. Wolf is derived from Goth. vulfs and A.-Sax. vulf, with the root of Goth. vilwan=L. rapere, to lay hold of, to tear. 1 Wolframm and Wolffert were used as late as the last century. The name is then explained as indicating that this mineral, when brought together with tin-ore in the furnace, wasted the tin—ate it up as a wolf 134 Derivations of Mineral Names. The Sansk. karawa is the root of Gr. xopaé, L. corvus, It. corvo, Sp. cuorvo, Fr. corbeau, Engl. crow, G. Krdhe, Sw. Kraka, D. Kraye, on the one hand, and, on the other, of A.-Sax. cravan, O. H. G. hraban, G. Rabe, Fr. ravineux, Engl. raven. The derivation of Wolfram from Wolf and G. Rham=cream, is faulty. The Engl. name for G. wolfram is tungsten, der. Sw. tung- sten, from tung, heavy, and sten, stone. NICCOLITE, in this form of orthography, is derived from N. L. niccolum, the metallic element, formerly nickelum (latter part of eighteenth century). The Goth. nickr or nickl, A.-Sax. nier or nicor, Icel. nikr (related to Icel. hnickia=to seize and carry off), was a demon who inhabited pools of water and drew down his victims with irresistible force until they were drowned. From the above is derived the G. Nixe, a female water-spirit, who was not always cruel, but sometimes gave her valuable services to unhappy lovers and others who sought her aid. The G. masculine Mix belongs to the same family, but was a morose, objectionable character. His name serves to this day in Germany to drive children away from water. From the same source we have obtained the appellation “ Nick,” commonly used as “ Old Nick,’ now employed as a nom de plume for the chief of the infernal regions, although the original association of the name with water is hardly in keeping with the orthodox conception of this warmly-located ruler. In O. H. G. nickel signifies a small horse, especially a vicious one; also a dwarf. The A.-Sax. nag is related to it. Locally, the idea of a dwarf or stunted animal of any kind was modified into the personification of a malicious, mischievous spirit. In this connec- tion, the words Engl. nagging (from A.-Saxon) and G. necken, to tease, were used, The German miners frequently found ores which looked very promising, but, upon being smelted, they produced no silver: on the contrary, they emitted foul and noxious odors. The most natu- ral explanation, at that time, seemed to show that wicked, envious spirits had changed the ores, or even infested them: whereupon the terms nickel and kobold were freely applied to such disturbing ele- would. ‘‘ Er (wolfram) betreugt die Berglente gar sehr, weil er mit dem Zinnstein vor dem Wasser stehet und im Schmeltzen das Zinn raubet.” (Bergwerck’s Lexicon, 1743.) Wolfram was also used for some arsenical ores which are objectionable in the furnace. (Mineral, Belustigungen, 1768.) Derivations of Mineral Names. 135 ments. An association of “nickel” with the name of any other metal expressed the old Germanic idea of a “changeling” (G. Wech- seling, from O. H. G. wihseline), derived from the fancied changing of children by elves and fairies. Thus, copper-nickel would be the name of a mineral resembling copper-ore, yet containing none of the latter metal: the meaning would be equivalent to “false copper.” In this way the names of nickel and kobold became attached to certain minerals which resembled rich ores, but yielded neither sil- ver nor copper. . To this day the word nickel is applied to persons in certain parts of Germany when a giddy, or even vicious (gener- ally female), character is to be described. An ore known as Kupfernickel in Germany,. coppar-nickel in Sweden, yielded a grey, hard metal to the Swedish mineralogist Cronstedt, in 1754, which he named nickel. He took the name | from the ore. Promptly discerning that the metal he had obtained bore no relation to the first part of its name, copper, he selected the second. Thus the word which had first been applied by the miners was eventually attached to the metal which had caused them so much worriment. CoBALTITE is immediately derived from N. L. cobaltum, the metallic element. Agricola says (1546): “ Est preterea aliud genus ferrei quasi interdum coloris, cobaltum nostri vocant.” In O. H. G. thë word is Kobolt, sometimes Kobalt; in the sixteenth century, Kobeit and cobelt, or cobel; H. G., Kobalt; Sw., kobolt. It is a descendant of the Gr. xoßałoç, L. cobalus, whereby a familiar spirit was designated. This spirit was not necessarily vicious or ill- natured, nor prone to do harm, but he was full of mischief and fond of practical jokes. Aristophanes (about 406 B.C.) characterizes a xoßałoç as a satyr, a roguish fellow, in the following of Bacchus. The Fr. gobelin and Engl. goblin are derived from the same root. An amusing explanation of their etymology assigns Fr. gober= gobble, as their root and that of kobold, because nurses are apt to tell children tales of spirits that will “ gobble” them as a punish- ment for disobedience and other childish peccadillos. (Minshew.) In Germany the Kobold was rather useful than otherwise, unless he was crossed in anything.! Of a particularly industrious servant 1 Of the ‘‘ Berg-Kobelt”’ (mountain spirit) the following is said: ‘ Es lässt sich in allerhand Figur sehen, bissweilen als ein kleines Kind, auch wohl als ein alter Bergmann, nur muss ihnen nichts in Weg gele- 136 Derivations of Mineral Names. it was said: “ Sie hat einen Kobold” (a kobold is with her); and it was believed that this amiable spirit assisted her in her daily work. The underground association with nickels, however, must have tended to corrupt the kobold’s kindly disposition and to sharpen his enjoyment of practical jokes, which he carried even to the point of cruelty. He disturbed and hid the tools of the miners, interfered with their timbering, changed their ore, and played a thousand dis- tressing pranks. When the workmen proceeded to smelt silver from their ores, he caused the latter to emit mal-odorous, choking fumes in such dense masses as to injure the smelters. “ Kobelt’sche Ertze sind wilde und strenge Ertze.” (1743.) The heavy, white smoke spread itself upon the grass of the fields and killed the cat- tle. At last the kobold became identified with this fuming, smok- ing class of arsenical ores, so that Mathesius, in 1562, describes - cobalt as a “poisonous and injurious metal.” Linneus mentions arsenic (the source of the fumes) as Kobolt, and to this day the “ Scherbenkobalt” of German miners is but a variety of metallic arsenic. The metal cobalt was not extracted from its ores until Brandt, in - 1733, produced it in asomewhat impure state. Its blue glasses and slags became known about the middle of the sixteenth century by accident: a workman secretly threw a piece of the evil-minded “kobold” into his employer’s glass-furnace with the intentiun of causing the spirit to work dire mischief: the most beautiful blue glass resulted. Basanirr is derived from Gr. Sacavog=touchstone, probestone. It is used by Pindar in this sense as early as about 490 B.c. The word is formed from facavefw, possibly produced by contr. Gr. Baars, foundation, bottom, and vetw, I wash, clean—conveying the idea of “ sifting to the bottom.” The Latinized form, basanites, was indifferently applied to black quartz, the true probestone, and to basalt, the eruptive product. It has been claimed that a “typographical error” on the part of some early copyist bore the responsibility of having produced the latter word. The transition from basanites to basaltites seems easy. Pliny (A.D. 70) uses basaltes, a marble from Ethiopia, and speaks of the name as having been used before his time. get werden, so lässt es die Berg-Arbeiter auch zu frieden.” (18th Cen- tury.) Derivations of Mineral Names. 137 It is known to be a fact that basanites was applied to true basalt. Agricola (1546) uses the word for an undoubted basalt; Gessner (1565) derives it from Gr. pasavw, and applies it to true basalt ;! Kentmann (1565) calls it “ black marble,” and uses the word in the same way ;? Basanite is described as “black stone” by Leon- ardus (1610), and he speaks of “ Bazanites sive Basaltem lapis ;” Cæsius quotes it as “iron-colored” marble, in 1636; in 1743 (Berg- werck’s Lexicon) it was regarded as a dark-grey marble (“ schwarz- grauer Marmor”); within the last fifty years Basant and Basalt have been used synonymously in various German publications. This confusion of he. ss? terms may bear out the idea of an ay “typographical error.’ CELADONITE is formed from the Fr. celadon=sea-green. The origin of this word, in its quoted meaning, seems to be a curious one. Gr. Kejadwy first occurs in the “ Iliad” (880 B.c.) as the name of a river; subsequently it is repeatedly used in the same way by Meleagros, Strabo a. o. ; Ovid incidentally applied it, in the form of Celadon, as the names of two men, one from the mouth of the Nile, the other from the mountains of Thessaly. The word is — derived from Gr. xeAadoc¢=rushing noise, like that of rushing water. In 1610 (1616?) a French novelist, D’Urfée, wrote a pastoral romance, “ Astrée,” in which he gave the name of Celadon, bor- rowed from Ovid, to an inexperienced, insipid lover: whence the idea of greenness (Dana). Spanish (?), French and German all contain the noun Celadon or Seladon=verdant lover (G. blöder Schäfer), and the adjective=sea-green. In Engl. the latter has been amplified to celandine. In the acceptation of verdant lover, the word seems to have come from the Spanish rather than from the French, but it is difficult to arrive at its meaning for any given date. There was an ancient river Celadon in Spain, whence the word may have been introduced into that language. Thompson uses the name, in 1727, in “ The Seasons,” for Amelia’s lover. Dana gives the derivation from Gr. xehadov=burning ; others from 7¢ic<0oveov—=swallow-wort. But neither seems to apply.

Some of the ancients claim that it prevents the latter, but Plutarch denies it. Among its numerous wearers of the present day, some may be able to judge of its supposed merit in this direction. “Magorum Yanta resistere ebrietati eas promittit et nide appella- tas.” — Pliny. The amethyst is mentioned by Plato (400 B.c.) and Asclepiades (280 B.c.) as a gem, 6. A few mineral names have reached us from the Anglo-Saxon with hardly a change and without having lost their characteristic brevity :— Wap isa bog-ore of manganese. The word takes its origin from A.-Sax. vaed, bunches, derived from the es vidan=to bind (in bunches). We further have: O. H. G. wat, wetan, gawati ; M. H. G. wat; Scandinavian vad; Sw. sald lated to G. Watte (cotton-), batting, and to Engl. weeds. Fuint has been referred to Gr. mèvĝoç=tile or brick, and to Gr. z/yttevy=to strike, in allusion to striking fire ; but these deri- vations seem very problematical. The word in A.-Sax. was flint; M. H. G., vlins ; locally (Middle German), vlint ; O. Engl., flent; Sw., flinta. “ And out of flent sprang flod, that folke and bestes dron ken.” — Langland, 1862. French flin means polishing material, for which powdered flint may be used. The word flent or flint may be related to the root of flensing=to skin, to flay (Icel., flisia), as in the earliest times flint, particularly, ae other stone implements were used for skinning animals, The form flint was assumed long ago :— “ Had ben my heart of flint, it must haue melted.” —Surrey, about 1520. The H. G. Flinte=(shot-), gun, is the same word applied to fire- arms since about 1640, when they were first supplied with chips of flint or chalcedony for the purpose of ae fire and igniting the powder. 7. Matters of historical interest are also alluded to in mineral $ x Aa AA G SEa aaa S a daa a ee E ENN ASE As A SIEA Derivations of Mineral Names. 139: names, but, usually, refer to some scientific work rather than to political occurrences. TANTALITE is a name given by the Swedish mineralogist Eke- berg toa certain mineral in 1802. He thereby expresses the difficul- ties and tantalizing perplexities with which he was beset during the progress of his analysis of the substance. It is named after Tan- talos, the well-remembered mortal favorite of the Olympian deities, who so far presumed upon his privileges as to place before them the remains of his own son, disguised asa tempting dish. For this sacrilege he was condemned to suffer hunger and thirst in the nether world, though surrounded by luscious fruits, viands and liquids of all kinds, which promptly receded from his grasp whenever he reached for them. Certainly, the name forcibly expresses the feelings of the baffled chemist, while at the same time it affords a glimpse of the status of | analytical science in 1802. XENOTIMITE.—[In 1832 the famous French mineralogist Beu- dant named a mineral Xenotime, apparently from contr. Gr. evoc, a stranger, and zzy7, honor. He explained, however, that this name was derived from contr. Gr. xevoç, empty, vain, and Teu), honor, and added that he intended it to recall the fact that the Swed- ish chemist and mineralogist Berzelius vainly thought to have found in this mineral the metal Thorium, which he had named (1815) be- fore its existence was really established (1828). The honor which Berzelius indirectly claimed in the supposed discovery of a new element was an empty one in this instance.! As Dana appropriately remarks (System Mineralogy, p. 529),. “there is a sneer at the great Swedish chemist in the name which Should have occasioned its immediate rejection.” If the word were correctly formed, so as to express what Beudant intended that it should, it would have been Cenotime or Cenotimite : hence the name, . as he writes it, fails to convey the implied meaning. Dana has accepted the name Xenotime, as he explains, because it “may be- _ *“Conformément principes q doptés, nous luisavons imposé un nom particulier, qui rappellera que le phosphate d’Yttria a été pris pour oxide d’un métal nouveau auquel on avait donné le nom de Thorium, apliqué aujour d’hui au métal découvert dans la Thorite.’’ —Traite de Mineral. 1832. 140 Derivations of Mineral Names. regarded as referring to the fact that the crystals are small, rare, not showy, and were long unnoticed.” YENITE is a name given by the French scientist Le Lievre, in 1807, to a mineral found on the Island of Elba. The name was bestowed in commemoration of the battle of Jena, October 14th, 1806, in which Bonaparte almost annihilated the Prussian army. Apart from the fact that the name should have been formed Jenite or Jenaite, the ungenerous spirit which prompted an intro- duction of political feelings into scientific matters was repudiated by Le Lievre’s own countrymen, as well as by the displeased Ger- mans: the name I/vaite—from the L. name of Elba—given to the mineral by Steffens in 1811, was substituted for Yenite. The hereditary rivalry between the French and German nations has found expression, within the last few years, in the naming of two newly-discovered elements: Gallium was named by a patriotic Frenchman, only to be followed by Germanium a short time after. 8. Naming minerals after localities is by no means an innovation, as the following examples will show :— Magnetite.—About 400 B.c. the Greek term 2edoc ‘Hpaxieca was used by Plato to designate a mineral with magnetic power. Pliny quotes it as Heraclion. Probably it was named after Hercu- les (Herakles) in intimation of its strength (lapis Herculeus was used in the sixteenth century), rather than after the town of Her- aclea in Lydia. Pliny claims that it was named after a shepherd, its discoverer.' Later on, Dioscorides a. o. use the term deo¢g parys, describing a magnetic stone supposed to have come from Magnesia, a portion of Thessaly. JePog payvytyc, used by Dioscorides also, referred to soapstone or talc, so far as can be determined. (Dana and Pape.) The name reached Germany in the period of M. H. G. and took the form of aget-stein or agt-stein. It was applied rather indiscrimi- nately, and apparently to amber by preference. The latter attracts small bits of paper and wool, ete., after having been subjected to friction. 1 “Sideritin ab hoc alio nomine apellant, quidam Heracleon. Magnes — apellatus ab inventore (autor est Nicander [about 150 B.C.])in Ida reper” tus est.” . . . “ Invenisse autem fertur, clavis crepidarum et baculi cus- pide herentibus, cum armenta pasceret.”’ è Derivations of Mineral Names. 141 The Gr. payvyg entered L, as magnes, thence passing into It. magnete, Sp. magnetico, Fr. magnetique, M. H. G. magnes, H. G. magnet, Sw. magnet, O. Engl. magnes, Engl. magnet. tt On th’ other syde an hidious rock is pight Of mightie magnes-stone.”’ — Spenser, 1552-1559. COPPER was obtained by the ancient Greeks from the Island of Cyprus. Homer speaks of it (880 B.C.) as yadxo¢ ; and qualifies this term, which meant ore, bronze, metal or copper, by giving its color as gud oc=red. Later on the same name was applied to iron, and then the distinction yasxog Kuzpcoc=Cyprian metal, was made, in order to avoid confusion. In L. the word aes is equiva- lent to the Gr. yaìxoç; and the copper became known as aes Oyp- rium. (Pliny a.o.) By the end of the third century the word aes was dropped, and the descriptive adjective Cypriwm evolved into the noun cuprum. The alchemists gave copper the name and sign of Venus. Kurpcc is an old poetical name for Venus, used by Euripides (450 B.C.) a. 0., and the Island of Cyprus was devoted to her cult. From L. aes Cyprium and M. L. cuprum have sprung: A.-Sax. cyper, O. H. G. Kuphar, H. G. Kupfer, O. Fr. cuyvre. Fr. cuivre, Sp. cobre, Sw. coppar, D. koper, O. Engl. coper, Engl. copper. “ Lyke as to a true syluer grote a false coper grote,” ete. —Sir T. More, 1478 to 1535. Turquols is really an adjective=turkish (from Turkey), and is taken directly from the French. In Middle German the word was turggis ; M. H. G., turkoys. In the middle of the sixteenth century this changed to Tiirckis and Türkis. The Sw. is turkos. N. L. forms are: Turcois, turcosa, turchesia ; It., turchesa, turchina ; Sp., turquesa ; O, Fr., turquoise; O. Engl., turques; Engl, turquois. j “I bequeth a ryng of gold, sette wta turques, a dyamaunt, and a 4 ruby.” 3 —Fabyan, 1512. There are a few names, familiar to almost every one, that have an exotic sound, foreign to that of the languages which have princi- pally furnished the material for mineralogical nomenclature :— i TOURMALINE—also known as Turpelin during the last century, is derived from the Cingalese turamali. 142 A Month in Paldéwan.

Te island of Paláwan, or, as it is more frequently called by the Spaniards, Paráqua, is classed as one of the Philippine group. It runs from the northeast to the southwest, and is something over 250 miles long, while it hardly averages 20 miles in width. It fronts the China sea on the west, and the Sulu or Mindora sea on the east. It is distantly connected on the north and east with the ‘other Philippines—through the Cuyos with Panay, and through the Calamines with Mindoro and Luzon ; but itis much more closely connected on the south by Balabac and other small islands with Borneo. It is mountainous and heavily timbered, and but thinly inhabited, the native population being estimated by the Spaniards at ten or twelve thousand. The native people are of at least two races, Malays and Negritos. The southern end is chiefly inhabited by people of Malay race, to whom the Spaniards give the name of their hereditary African enemies, Moros or Moors. They are Ma- hometan in religion, and this, with the presence of their priests, has kept them more or less united, and perhaps a little in advance of the northern tribes. The northern part is inhabited by savages of Malay race, living in small, scattered tribes, and of Negritos— wooly-haired black people—living in much the same state, and ap- parently amalgamating with the Malays. The Spanish have had some small settlements of Christian Indians from Luzon, at the north, for some time, and for fifteen or twenty years have been forming a convict town at Puerto Princesa, on the east coast, and near the middle of the island. This now numbers some twelve or fifteen hundred inhabitants, mostly criminals shipped there from other parts of the colony. This is the capital and residence of the Spanish governor and other officers. Within a few years the Spanish have also formed small military settlements on the west coast. A Month in Palawan. 143 Our party from the University of Michigan reached the island about the first of September, 1887, in the midst of the rainy sea- son, but as the showers. usually came in the afternoon, we were able to do a good deal of hunting and other collecting in the forenoon, while we spent the afternoon in skinning and preparing the collec- tion of the morning. From lack of roads or other means of com- munication, our work was done chiefly on the low, heavily-timbered peninsula on which the town is built. We also did some work across the bay, along the little river Iguahit, and about a village of natives who called themselves Tagbaunas. The collections made by us during the four weeks of our stay numbered about seven hundred birds of some one hundred and twenty species; thirty mammals of five species; thirty amphibia of three species; one fresh-water turtle ; fifteen lizards of six species; fifteen snakes of nine species; three hundred butterflies of thirty species; a few small and inconspicuous beetles, scorpions, and centipedes ; ten or twelve species of corals from the shallow waters of the bay, and a large number of fine land and tree shells. The island has been considered to belong to the Philippine group zoologically as well as politically—Mr. Wallace dividing the Indo- Malayan sub-region into three divisions: Java, Sumatra, Borneo, and Malacca, and the Philippines. Our work would seem to show that Palawan is much more nearly allied zoologically to Borneo than are the other islands of the group, and probably more nearly allied to Borneo than to the other islands. This state of things seems to be especially shown in the mammals, in which the island is much richer than the rest of the group. It possesses, in common with Borneo and the other Philippines, the common gray monkey, Maca- cus cynomolgus, a species of Tupaia, one of squirrels, a wild hog, and one or two species of civet cats. In addition to these we found the manis or pangolin and the binturong, both common to Borneo, but wanting in the rest of the Philippines. We also became satis- fied of the existence of a porcupine, Hystriz, a large round-tailed flying squirrel, Pteromys, and of a small species of the Mustelide, with powerful and unpleasant odor. Besides these Bornean forms | there is probably also a species of tree-cat, Felis, and a mountain goat in the island. These species rest on the evidence of Spaniards and half-breeds capable of observing, and worthy of credence. In addition to these the savages declare that there is an orang outang in the interior. The mammals common to the rest of the Philip- 144 A Month in Paléwan. pine group and wanting in Paláwan are also noteworthy. Deer, present everywhere else, are said not to exist, and we saw no signs of them. The kaguan or Galeopithecus, one of the most common Philippine mammals, is apparently absent heres These facts seem to show that Paliwan has received its animal population from Bor- neo at a different time and through a different route than the rest of the group. The intervening island of Balabac possesses the com- mon monkey, the wild hog, a true squirrel, a porcupine, an ill- smelling weasel ; lacks the manis of Paláwan, but has a diminutive deer, Tragulus, common to it and Borneo. In its birds Paléwan also shows its closer connection with Borneo. Among Bornean forms which do not seem to have made their way into the other Philippines, are the two beautiful genera of greenlets, Tora and Phyllornis ; a three-toed woodpecker, Tiga ; a true pheas- ant, Polyplectron, closely allied to the beautiful glass pheasants of Borneo and Malacca ; and a frog-mouth (Podargus) bird, allied to the goat-suckers, but with the mouth parts (beak) heavy and hard. The Bornean look of our birds is quite apparent when we compare them with birds from the other islands, and careful study will prob- ably show many more instances than those above mentioned. Sun-birds, kingfishers, cuckoos, and swifts were especially abund- ant in species and individuals. About September 20 we began to find large numbers of titlarks, snipes, plovers, and sand-pipers, and concluded that this must be the advance of the fall migration from the northwest. The only arboreal species which seemed to arrive at the same time was one of the warblers, Sylviide. We undertook to make as careful notes of habits, height of flight, and feeding, character of foods, etc., as was possible in our hurried stay. Tropical species of birds seem to be much more nearly lim- ited to specific kinds of food than those of temperate countries. A careful examination of the stomachs of our collection showed that some species lived entirely upon ants, others upon centipedes, others upon some special kind of fruit, etc., ete. The three-toed wood- pecker noted above lives exclusively on ants, and these possibly of a single species—at least all of the same color; while a four-toed species (Chrysocolaptes), much like the three-toed one in size and color, lives on the common larval food of the family. One splendid long-tailed cuckoo, with beautiful metallic-blue coloring, bare spots of vivid crimson about the eyes, and immense light-green beak, Intelligent Selection. 145 were exactly alike in the sexes with the exception that the male had eyes of cherry red, while those of the female were yellow—and this uniformly so through six or eight pairs proeured. We shall take means for a more thorough study of the mammals of the island than was possible during our snort stay. We have come on to the port of Zamboanga, in the island of Mindanao, and purpose to make a collection of the same character here. INTELLIGENT SELECTION. BY CHARLES MORRIS. wat do not distinct species of animals and plants appear as a consequence of man’s selection and preservation of varieties ? This is a question which has been asked more often than it has been answered, and which yet remains to some extent an open query. Among domesticated animals—dogs, pigeons, and a few other species in particular—the varieties produced by selection have been very numerous and well marked, yet they still remain dogs, pigeons, etc., and there is no generally accepted evidence that a new species has ever been produced by this method.! Yet though much has been said on this question, it is by no means exhausted. There is one important circumstance which does not appear to have been considered, and which therefore gives war- rant for a further review of the subject. It is not sufficiently borne in mind that the production of, and experiments on, varieties of animals and plants has been left almost entirely in the hands of ordinary industry. Science has come in to examine the results, yet has had little to do with the experiments. These have been gov- erned almost solely by pecuniary considerations; yet it must be ad- mitted that what may be admirably calculated to make money may be valueless to science, and that had a long series of experiments been conducted for scientific purposes alone, the results must have z It is necessary to state, however, that many scientists hold that new Species, and even genera, have been produced in domesticated animals. The carrier pigeon, for instance, is looked upon as a well-marked and persistent species, while variations in the dentition of dogs, of generic value, have been observed. Changes of this character are of the kind which it is important for scientific observers to endeavor to hereditarily transmit, and render permanent. 146 Intelligent Selection. been widely different from those that have appeared, and may have | been far more significant. That distinct species could have been thus produced is quite within the limits of probability. We have named this process Intelligent Selection, as distinguished from Natural Selection. Yet in reality, though the former is con- ducted by man’s intelligence instead of by the unaided influences of nature, there is no actual difference of principle between the two methods of selection. The changes which proceed with inter- minable slowness in the one case are greatly accelerated in the other ; yet while Natural Selection is the work of nature unaided, Intelli- gent Selection is but the work of nature aided. The influences tending to favor and preserve variations which nature employs occasionally and slowly, are frequently and rapidly employed by man, and thus animals and plants exhibit wider variations under man’s hands in years than they do under nature’s hands in centuries. Yet the principles which control the preservation of varieties are probably much the same in both cases, and all that man has done has been to accelerate the process. If, as is ordinarily believed, no new species or genera have been produced by man, though such have abundantly appeared in nature, a marked discrepancy would seem to exist between the action of Intelligent and Natural Selection. But it must be borne in mind that nature produces an extraordinary number of varieties as pre- liminary to every new species that appears. Ordinary variations are superficial, and of non-specific value. Variations in specifie characters are probably of rare occurrence, and their preservation yet rarer. Possibly they only arise as resultants of a long series of minor variations in the same general direction. If such be the case it is not surprising that the superficial variations with which man has to deal seldom or never accumulate into characters of spe- cific value—particularly in the lack of scientific direction. Yet that species have not been produced by man is more an as- sertion than a demonstrated fact. If we take the varieties of dogs, for instance, such wide differences in size, form, and habits appear that many of these varieties, if found in nature, would be at once aecepted as well-defined species. Yet it is declared that these dis- tinctions are but artificial, and would very quickly disappear if the dogs were restored to nature. This assertion is ordinarily quietly - accepted, yet it remains but an assertion. No one has ever proved Intelligent Selection. 147 it. The fact is that while such dogs as preserve their natural instincts and conditions with little impairment might regain their original feral condition, those whose variation is extreme would simply die out. They could not survive in the struggle for exist- ence if immediately removed from the artificial conditions to which they have been accustomed. Yet if two widely different varieties of dogs were slowly restored to nature, being protected and fed until they had learned the art of self-preservation without man’s care, it is by no means improbable that they might retain their peculiar characters of form, habit, and adaptation to particular food, and if interbred for a considerable period might continue to interbreed. Though there is no proof of this, there is no disproof. It is an open problem, which can be settled only by experiment. The state- ment that all variational differences would disappear if any of the domesticated species were restored to feral conditions, is an unproved . assertion, which cannot be verified without a much wider series of scientifically-directed experiments than have yet been made. Doz- ens of problems of this kind are settled in men’s minds. Very few of them have been settled in fact. It will be of interest, in this connection, to consider what has actually been done by Intelligent Selection, and the influences which have controlled its results. A mere glance at the subject shows us that industrial and pecuniary considerations have almost solely been at work. Among trees, for instance, the effort has been to select fruits of large size, agreeable taste, and early or late maturity. Among flower bushes, bright colors and odd shapes of petals, with variations in the size of the flower and its number of petals, have been the ruling considerations. Commercial value has been the sole thought, and superficial variations only have been preserved. A scientist would have watched for changes in the character of the pistils and stamens of the flowers, and if such appeared, by their - careful preservation might in time have produced undoubted new species. Yet no extended series of experiments from this scientific point of view has been made, so far as the present writer is aware. Such changes may be of- comparatively rare occurrence and incon- spicuous, yet there can be little question that they occasionally arise, and they may be as susceptible to selective processes as any other variations. Among animals the purposes aimed at by trainers vary in the case 148 Intelligent Selection. of almost every species, yet they are, as a rule, all industrial. In the horse, for instance, the properties selected are speed, graceful- ness of form, size, endurance, muscular strength, etc. In cattle milk-giving properties and delicacy of flesh are sought. Sheep are selected for fineness of wool and palatableness of meat. In swine pork-yielding powers are the sole consideration. Among domesti- cated birds, egg-laying powers are the main consideration in the hen, while in all these birds delicacy of flesh is particularly considered. Beauty of plumage and peculiarity of form are also favorite selective properties, and particularly in the case of pigeons, which have . yielded extraordinary diversities in this respect. In all these experiments but two considerations have ruled : the commercial value of the product, and its adaptation to man’s pleas- ure. The money it will bring, and the enjoyment it will give to man’s senses or his appetite, have been the overruling influences in the selection of varieties of plants and animals, and if any variation approaching specific value has been preserved, it has been through chance rather than design. The characters sought for have been superficial ones only, and in consequence superficial varieties mainly have been obtained. Had this long series of experiments in selection been conducted by scientists, and for scientific purposes only, the results must have been widely different. The commercial value of the product might have been much less; the scientific value must have been much greater. Among the innumerable variations in form and character of animals and plants which incessantly appear, there must be some of more essential and less superficial significance than others. _ Only the eye of a trained scientist could discriminate between these, and by persistent selection of such variations, and neglect of all others, there can be no doubt that the question as to whether species can be produced by intelligent selection would have been far nearer settle- ment than it is now. In the case of only a few animals has the consideration in selec- tion been other than to aid in the support or to administer to the pleasure of man. Of the species in which wider purposes have ruled, the principal is the dog. In this animal there has been little tendency to subvert the natural instincts. Most of the domesticated species have been so diligently cared for by man that they have lost the ability to care for themselves, and the intelligence which they Intelligent Selection. 149 possessed in their wild state has disappeared, and been replaced by no new intelligence. There are no more stupid animals on the face of the earth than the cattle and sheep of the farm. The hog and the horse are less so, the former because he has preserved some degree of feral independence, and the latter because his duties have required some degree of intelligence. But the dog has protected instead of being protected by man, and has thus, except in some special varieties, retained its natural intelligence. And its employment under man has been such as to develop and preserve a new intelligence. The dog has been for ages man’s companion. Its natural instincts have been retained, while upon them have been laid new instincts of the same general character ; and its powers of observation have been very greatly widened and sharpened. It has been in contact with men mentally, and its own mental powers have been developed thereby. And finally selection, while devoted largely to peculiarities of form, has been yet more largely devoted to peculiarities of habit—to intel- lectual characteristics. Intelligence has been selected in dogs, and in this alone of all domesticated species. Of the other species on which selection for intelligence might have been practiced, preventive circumstances have hindered. The cats are natively as independent as the dogs. But the domestic cat is only in a minor sense a tamed animal. In its reproductive habits it is a wild creature. In consequence selection has been almost im- possible, and very few varieties of cats have appeared. Such as- exist, indeed, are probably due to natural, not to intelligent selec- tion. The monkeys, and particularly the higher apes, would be remarkably well adapted to selection for intelligence, but unfortu- nately they do not breed well in captivity. The anthropoid apes indeed, not only do not breed, but have never lived long in cap- tivity, so that this promising field of selective experiment is practi- cally closed. What results might arise could a fertile domestic race of orangs or chimpanzees be produced, it is not easy to decide. The marked intelligence and teachableness displayed by individuals, with no hereditary powers but those derived from a wild-woods life, is significant of remarkable developments could they be made to breed in captivity. It would not be easy to give them new vocal organs, and teach them to talk, but by long-continued selection their brains might be developed in size and power until they became the equal in intelligence of some of the lowest savage tribes of man. 150 Intelligent Selection. Dogs are the only species which promise good results in selection for intelligence, and it is highly desirable that experiments on them, with this purpose in view, should be made. The desultory selection which has been practiced has given excellent results in this direc- tion, while many instances of high intelligence in individual dogs have appeared. But no breeder seems to have made it his business to make this intelligence the basis of his selective operations, though it has been done to some extent without design, in the effort to pre- serve high-bred varieties. It is desirable that a series of scientific experiments with this object in view should be undertaken, the intel- ligence of individual dogs being awakened as fully as possible, and the same training applied to the offspring of these dogs during a number of generations. The result could scarcely fail to be of interest and importance. In fact it is desirable that scientists should give some attention to the general subject here considered—that of intelligent selection of varieties of animals and plants for other purposes than those of com- merce. Many results not now dreamed of might thus be attained, and the problems of the origin of species and the limits of animal intellect be brought nearer to solution. When such extraordinary results have been produced by the chance methods .of selection of superficial traits so far practiced, the adoption of scientific methods and the selection of more significant characteristics would very likely yield varieties of the utmost interest and value to science. Editors’ Table. 151 EDITORS’ TABLE. New popular scientific journals are appearing or are announced from time to time. We have received the first number of the American Geologist, which is published at Minneapolis. As its title implies, its field embraces geology and all the immediately allied and subordinate sciences. Its editorial corps embraces some of our most able and accomplished geologists. It deserves success, and our country is large enough to ensure this, if its people are sufficiently interested in the subject to subscribe for it. Another important journal is announced by a New York com- pany, to be called Garden and Forest, which is to be a Journal of Horticulture, Landscape Art, and Forestry. Its editors are to be Professors ©. S. Sargent and W. G. Farlow, of Harvard, and Professor A. S. Packard, of Brown. This journal is designed for a comparatively wealthy constituency, and will not be, apparently, exclusively scientific, although its editorial corps is highly so. So far as the publication of new scientific journals is concerned, we cannot have too many of them if they are well backed or sus- tained, financially. Unless this be the case, however, we regret the loss of time and labor which they cause to their projectors and con- tributors. Experts in science are not sufficiently numerous in this country to enable us to spare any of them for popular work, unless they are so compensated as to prevent any actual loss to their scien- tific efficiency. It may be safely assumed that every really merito- rious work of a specialist which is produced in this country will have ten translators, even if his work reaches the American public by way of Europe, before it is appreciated. Tt is easier to compile than to produce. We have had some experience of the financial aspect of the ques- tion. The perils are many and various. The NATURALIST, although now in its twenty-second year, has escaped shipwreck by little less than a miracle several times. But the maxim, “ while there is life there is hope,” has been as often verified, and the vigorous consti- tution which comes of—modesty forbids us to say just what—has triumphed, while many of our contemporaries have “joined the majority ”—of popular scientific journals. 152 Recent Literature. RECENT LITERATURE. CLAYPOLE’S “ THE LAKE AGE IN On10.” !—The course of the terminal moraine in Ohio is westward from the New York line to about the middle of the State, after which it swerves south and - southwest so as to cross into Kentucky. “The ice,” says our author, “dammed the Ohio River above the site of Cincinnati, ” forming a sheet of water which he names “Lake Ohio.” As the banks of the Ohio are 400 to 500 feet high at Cincinnati, the ice must have been thicker than this. If assumed at 500 feet, the rim of the ice would be 365 feet above the level of Lake Erie. The entire south of Ohio, a large portion of West Virginia, and portions of Ken- tucky and Pennsylvania, including the site of Pittsburgh, must thus have been under water, forming a lake some 400 miles by 200. Professor Claypole, from the mass of the moraine, and other rea- sons, assigns considerable time to the life of this lake before the ice- dam gave way, at first to be repaired every winter, at last utterly. When the glacier, in its further retreat, had crossed the water- shed, the waters formed by its melting, unable to escape towards the north, formed a series of smaller lakes in what are now the val- leys of rivers flowing into Lakes Erie and Ontario. As a conse- quence of the still farther retreat of the ice, these lakes became confluent, the water was drained away from those that lay highest, and carried off through the lowest water-gap, paving the way for the formation of Lakes Erie and Ontario, which at one stage formed a single vast sheet of w For some time a narrow re A stretching across the St. Law- rence valley held the waters of this great lake at a level of 700 feet above the sea Professor Claypole traces the various steps of the ice retreat and lake formation with much care, and illustrates his argument with four maps.

The travelers followed the Yurangkash to its junction with the Karakash, and then proceeded along the wider stream (the Kho- ton) to the Tarim. After visiting the towns of Shah Yar, Kuchar, Karashahr, and Kurla, Mr. Carey pushed on to the Lob-Nor dis- trict. Miserable poverty seems the main characteristic of the Mus- sulman Turki-speaking natives of the Lob district, against whom their neighbors higher up the Tarim are much prejudiced. On April 29, 1886, Mr. Carey started for a pass over the Altyn Tagh, but the guide lost his way. After being compelled to burn the riS of a tent for fuel, the less barren valley of Bokalik was reached. After wandering in the mountains, guided only by a com- pass and sextant, for eighty days without seeing a human being, the party came upon several hundred armed pilgrims, and found that they were between the Kuen-Lun and Khokosili ranges, just south of the Angirtakshia Pass, and south of the Naichi valley, the point aimed at. Here much difficulty was experienced in procuring food, 1 Edited by W. N. Lockington, Philadelphia, Pa. Geography and Travel. 157 as the supplies of the natives had run short. In the course of a journey to a place called Hoiduthara in quest of barley, Mr. Carey and his Tartar (Daspa) were the recipients of great kindness from a young Lama, who, observing the exhausted condition of the pair, rode to the town and ten miles back to bring them food. After 37 days the two rejoined Mr. Dalgleish with supplies. Hajjar, the residence of the chief of the Thaichinenr Mongols, was next reached. Our traveler characterizes the Mongols as timid and poor, and so accustomed to being cheated by Chinese that they cannot believe anyone will treat them fairly. Makhai, the Sai- thang plain, and Sachu were the next points—the last a Chinese town built of sun-dried bricks, mud, and timber. At Hami, a Belgian and two Russians were found. At this point the travellers turned westward, and after passing by Pichan, (the frontier post of Kashgaria under Yakule Bey) and Turfan, made an excursion to Urumtsi, the headquarters of the Chinese Government of Turkis- tan. They then pushed on to the previously visited town of Kurla, and returned to Ladakh via Kuchar, Aksu,and Yarkand. r. Carey has thus visited almost every important place in Chi- nese Turkistan except Kashgar, and he states that it is for the most part purely desert, the only really good strip of country being in the west, and composing Kashgar, Kargalik,and Yarkand. The Chi- nese give complete religious toleration, repress crime well, and main- tain a high prestige. THe Tarm Disrrict.—The Tarim river had, in October, 1885, a ope of three to five feet, and a width of about 135 yards at the confluence of the Yarkand and Khotan. In summer the depth and width, as stated by the natives, and proved by the state of the river- bed, are thrice the above. It is only in summer that the Khotan- daria flows into it. The Tarim thus seems to be navigable for steamers from the confluence of the Yarkand and Khotan to the Lob-Nor. The map in a recent number of the Izvestia, embodying the results of the fourth journey of General Przewalski (Prejevalsky) in Central Asia, shows that the depression of the Lob Nor must not be confounded with the Eastern Gobi, which latter is more ele- vated, and falls by a steep terrace towards the depression of the b-Nor. Thus the Tarim region is a depression of the high plat- iar of ru Asia, limited on the east as well as on the north, west, and south. THe Mounratns or Stam.—Mr. J. McCarthy, who has for seven years been superintendent of surveys in Spain, states that the chain of mountains which runs on the west in an unbroken range to Sing- apore, has peaks of 7,000 feet between Burmah and Siam, while one peak in the Malay Peninsula reaches 8,000 feet. The eastern range, 158 General Notes. which forms the watershed between the rivers flowing into the Chi- nese sea and the Meinam Kong (Mekong), has peaks of 9,000 feet. Another range, which leaves the western range near Chingmai (Zimmé), forms the watershed between the Meinam and Meinam Kong valleys. Famous salt wells exist in this range at the source of the eastern branch of the Meinam. Arrica.—M. Dours? ADVENTURES IN THE SAHARA.—M. Douls, disguised as a Mussulman, landed from a Canary Island fish- ing boat at a point between Cape Bojadorand the Rio de Oro. The first Moors he met suspected him, and made him a prisoner, but by persevering in his rôle he was finally admitted:as a brother into the tribe, which proved to be a section of the terrible Ulad Delim, the robbers of the Western Sahara. For five months he wandered with them, exploring the desert of Uaran and Djuf, the great depression of the Sahara. In March last he was at Tendaf, the great slave market of the Northern Sahara. This oasis has greatly increased in size since Dr. Lenz’s visit in 1880. Taking leave of the nomads at Glimin, he proceeded across the Atlas through the country of the Berbers of Sus to the city of Morocco. Here he was suspected and thrown into a dungeon, but was fortunately liberated through the representations of Sir Kirby Green, the English ambassador, who reached the town the same evening. AMERICA.—SUBMARINE V ALLEYS OF THE CALIFORNIAN COAST. —Prof. Geo. Davidson (Bull. Cal. Acad. Sci.) describes the subma- rine valleys discovered off the Pacific Coast of the United States. Within forty or fifty miles of the shore south of Cape Mendocino the lateau of the Pacific reaches a depth of 2,000 to 2,400 fathoms. here is usually a marginal plateau ten miles wide to the 100 fathom curve, beyond which the descent is sharp to 500 or 600 fathoms. In this marginal plateau several remarkable valleys have been dis- covered. One of these is in Monterey Bay, heading to the lowlands at the bend of Salinas river; and another off Point Hueneme, at Geography and Travel. 159 the eastern entrance of the Santa Barbara channel ; there are one or two off the southern point of Carmel Bay, while the deepest one reaches far into the bay. Near Cape Mendocino, just north of a sub- marine ridge extending from Point Delgada to Shelter Cove, is a deep valley which breaks through the marginal plateau and runs sharply into the immediate coast line. The head of this valley, at oue and one quarter miles from shore, is 100 fathoms deep ; where it breaks through the 100 fathom line it is 400 fathoms deep. The slopes of the sides are very steep. Midway between this and Point Gorda is another valley 150 to 300 fathoms deep, reaching 520 fathoms where it breaks through the 100 fathom line. Another valley between Point Gorda and Cape Mendocino is 450 fathoms deep at a point six and one half miles southwest by south from the cape. This valley is a wide one; with green mud at its bottom. EXPLORATIONS ON THE YuKON.—Dr. G. M. Dawson and party left Victoria in May last with the object of exploring the tributaries of the Upper Yukon. He proceeded up the Stikine River as far as Dease Lake, and when, on June 18th, the ice broke up, went down the Dease River and into the forks of the Dease and the Liard. Mr. McConnell here separated from the party with the purpose of descending and surveying the Liard and Mackenzie, and will probably winter at Fo Simpson, on the latter river. Dr. Dawson went up the Liard and Frances Rivers to Frances Lake, which drains into the Liard ; then made a portage of fifty miles to the Pelly River, which they descended to the confluence of the Pelly and Lewis; and then ascended the Lewis, crossing the .Chileot portage to the head of Lynn Canal. GEOGRAPHICAL NeEws.—Mr. Cuthbertson has reached the summit of Mount Obree, one of the culminating peaks of the Owen | Stanley range. He makes it only 8000 feet high, instead of 10,246, as was determined by angular measurements taken by the tlesnake expedition. He states that at 2,500 feet above the sea he passed the point reached by Messrs. Hunter and Hartmann. The population of New Zealand in March, 1886, exclusive of Maoris, was 578,482, an increase of 33,549 over that of 1881. The figures include 4,527 Chinese, only 15 of whom are women. = Maoris number 41,969, and 2,254 half castes living with the aoris, M.

The other hills reach 600 to 700 feet. There is very little fresh water. The Danish Government has decided to despatch an expedition to Iceland this coming summer, to effect hydrographical measure- ments.

Dr. Krause has etki at Accra on the Gold Coast absolutely without means, having been compelled to leave his collections and baggage behind through the opposition of the natives. M. J. Thulet, from observations taken on the Clorinde combined with those of Mr. Buchanan on the Challenger, has prepared a series of longitudinal and transverse sections of the Gulf Stream. It is like a river, and has a steeper slope towards the United States than towards the ocean. The great St. Lawrence current, coming from between Cape Breton Island and St. Paul, collides with the Gulf Stream, lessens its speed, and leaves as a sort of submarine delta the banks extending along the United States coast to the great bank of Newfoundland. The eastern polar current skirts Newfoundland, strikes the Gulf Stream at right angles, and since its waters are a little lighter than those of the Gulf Stream, mixes with them, and almost entirely arrests them. The cooled waters spread out in a general north-easterly direction, but there is no longer any definite current. Geology and Paleontology. 161 e researches of General Tillo on temperature have led him to conclude that the continents are, as a whole, 3° cent. colder than the oceans. between the latitudes of 90° N. and 50° S. The New Continent is 3° colder than the Old; and the Atlantic 2.6° colder than the Pacific. The northern hemisphere contains 14 per cent. of the cold regions, 35 per cent. of temperate, and 51 per cent. of hot regions. Dr. Supan’s estimate, reached by a different method, gave 15, 32 and 53 per cent. for these regions. GEOLOGY AND PALZONTOLOGY. THE VERTEBRATE FAUNA OF THE PuERCO Epocu.—I have recently revised my material representing this fauna, and have added eighteen species to those already known. One of these belong to a new genus, viz.: Onychodectes, allied to Conoryctes (Creodont). The Puerco formation lies on the Laramie in North Western New Mexico and South Western Colorado, and is largely covered by the Wasatch Eocene in both regions. It was discovered by the writer in 1874, at its eastern outcrop of about 500 feet thick- ness, and was identified by Endlich and Holmes in Colorado, in 1876, where the thickness reaches 1000 to 1200 feet. On the San Juan river, its thickness is 700 feet, while at its western outcrop, south of that river, its thickness is 800 or 900 feet. While the formation possesses lithological peculiarities, no clue to its impor- tance in geologic chronology was known until the discovery of vertebrate remains was made in 1880, by Mr. David Baldwin. With the evidence derived from this material the writer has been able to interject into the series of epochs of geological time a period which must have possessed many peculiarities, and which differed in such important essentials from those which preceded and from those that followed it, that an immense interval between them is proved to have existed, such as had not been previously suspected. The rich fauna which it contains displays characters which indicate others yet to be discovered before connections with other epochs both prior and subsequent can be known. The vertebrate fauna includes up to the present date one hun- dred and six known species. Four species of Mollusca have been discovered, which have been determined by Dr. C. A. White, of, the U. S. National Museum. They are Unio rectoides White; Helix adipis White; H. nacimientensis White, and Pupa leidyi Meek. The first named is found in the Wasatch, and the last in the Laramie; the two other species are peculiar. Besides these; the only other indications of organic life at that period is petrified _ Wood of undetermined trees, which is quite abil : 162 General Notes. The character of the vertebrate fauna is indicated by the follow- ing table: Be Se re reer cca 12 BUDOLUGEIE i's ors cere so secceues 52 Crocodilitiws wise Ci cides 3 SOOMIOGGONRs oobi oe sce veel 3 Testudinata ................. 5 CPODGOIND sss 05 ecan an 49 Rhynchocephalia............ 3 DRROODOGM. 5 6 vic sae oa eaen 28 CPO oso ed ease ceieee cs 7s 8 1 Quadrumana...... ........ 4 NOT isk ieee Peas Condylarthra. i.. ccris 24 Mammalia. ocassion s n 93 ly Pode. ei na Marsupialia. a eceso oaint ona TOME 6 seee o a 106 In 1874, the writer advanced the proposition that the ancestors of modern placental mammalia would be found to be “ plantigrade pentadactyle bunodonts.” This anticipation was partly realised in the fauna of the Wasatch epoch subsequently discovered, but is complete- ly so, in the characters of the mammalia of the Puerco epoch. the placentals, and probably the Implacentals also, were “ plantigrade pentodactyle bunodonts.” More than this, the placentals nearly all present the primitive type of dendition of the maxillary series, since the superior no less are nearly all of the tritubercular type. But four species out of the eighty-seven placentals are quadrituber- cular. In the inferior molars the tuberculosectorial, or quinque- tubercular type of dertition is extensively prevalent, but not so gen- erally so as the superior tritubercular. Thus of the eighty-seven placentals sixty-four present the primitive type. n its relations to other faunæ, the Puerco is totally distinct as to species. No species comes to it from an earlier epoch, and none continued unchanged after it. Of genera not widely distributed in time, one of lizard-like Rhynchocephalia, Champsosaurus, comes over from the Laramie, with a genus of tortoises Compsemys. Another genus of tortoises, Dermatemys, probably commences at this epoch, to continue through the Wasatch and Bridger Eocenes to the present time, since it still exists in Mexico. Among Mam- malia, one genus only continues later, since Didymictis is found in the Wasatch and Wind-river formations. None other continues after the close of the Puerco. Not only this, but the entire family of the Periptychide ceased at that period. The same is true of the Amblypod family Pantolambdide. One of the most im- portant features of the fauna is, however, the presence of eleven species of the Marsuspialia Multituberculata, a suborder which com- menced in the Triassic age, and which terminated its existence so far as the Northern Hemisphere is concerned, with the end. of the Puerco epoch. This series of animals gives a Mesozoic character to the fauna, which is not necessarily counterbalanced by the characters of the remaining types. The placentals are in all probability those which existed during the latter part of Mesozoic time, and the absence of some of the forms of the Eocene increases the weight of the impression thus produced. Thus two orders Geology and Paleontology. 163 universally present in the Eocenes, the Perissodactyla and the Rodentia, are wanting from the Puerco. In conclusion it may be safely assumed that in the Puerco fauna, we find the ancestors of the species of Eocene and of later times. In the Tzeniodonta we get ancestors of Tillodonta and probably of Rodentia and Edentata. In Creodonta we get the ancestors of the Carnivora, in the family of the Miacide. In the Condylarthra, we get the ancestors of the Diplarthra and Amblypoda, and in the Puerco Amblypoda the ancestors of those of the following epochs. Hence the investigation of this fauna possesses an especial interest for the mammalogist and for the evolutionist, as well as for the geologist proper.—E. D. Cope. SCHLOSSER ON THE CÆNOZOIC MARSUPIALS AND Uneuicu- LATA.'—The first part of this work contains all of the Unguicu- lata, except the Edentata, Rodentia and Carnivora. The last- named order will form the second part. The work is an important one, in quarto form, and the first part is illustrated with five plates. This supplements the American works on the same subject and brings it up to the present time, with minor exceptions. The present author shows throughout, his fine appreciation of the points of structure of the vertebrate skeleton, and he makes judi- cious use of them, from a systematic point of view, although one observes, perhaps, a tendency to rather more minute taxonomic division than the circumstances warrant. The work is also char- acterized by a thorough acquaintance with the literature of the subject. Important additions to our knowledge are made in every department. e can only mention here the descriptions of the little-known genera of Von Meyer—Dimylus, Cordylodon and Oxygomphius, the first two remarkable forms of Insectivora. To the Creodonta he adds the new genus Pseudopterodon, which is founded on a species of about the size of a fox (P. ganodus), allied to Pterodon. Dr. Schlosser continues to exclude the Miacide from the Creo- donta; but he has not been aware that Scott shows that the lum- bar zygapophyses have the characters of the other members of that order or sub-order. For some unaccountable reason he places Estho- nyx in the Edentata. Numerous important additions are made to- the Chiroptera, in the genera Vespertiliavus and Pseudorhinolophus, ne of the most striking discoveries recorded is the fact that the sup canine teeth of the Lemurs of the present period are really the anterior premolars, as in the Artiodactyle genus Oreo- * Die Affen, Lemuren, Chiropteren, Insectivoren, Marsupialier, Creo- donten u.

This obvious fact has, curiously, escaped the observation of all the numerous naturalists who have studied this group. consequence, he separates the eocene forms, which have all true canines in the lower jaw, asa distinct sub-order—the Pseudolemur- idx. Should this be really a sub-order, the name Mesodonta would have been the proper one to employ ; but if a family only, then the term Adapide is applicable—which is, indeed, used by Dr. Schlosser in a restricted sense. Most of Dr. Schlosser’s new material is derived from the French phosphorites. We congratulate the author on the fact that no person can study this subject henceforth without the aid of this memoir. LYDEKKER’s CATALOGUE OF Fosst MAMMALIA IN THE BRIT- isH Museum, Parr V.'—We have in this part of Dr. Lydekker’s. Catalogue a valuable contribution to the subject of which it treats. The light thrown on questions of affinity and taxonomic usage is considerable, and supplements from a conservative stand-point the opposite tendencies of Dr. Schlosser. Our own view of the case leads us to adopt in most cases the aurea mediocritas between these two distinguished cultivators of the science. There is one point, however, in which we are compelled to agree with Schlosser and not with Lydekker, and this in a question of scientific purism of which the latter is in all other cases so able a defender. ‘This is in the matter of requiring a description,—whether good or bad mat- bev = as to the rule,—for a genus and other division above es, as an essential basis for a nomenclature. Æ. g., in the “ Cat- logue” we find the name Platychcerops used instead of Miolophus, although no reason for the separation of the former was ever given by its describer. Perhaps no description was given to Miolophus either. In that case Dr. Lydekker has the right to select whichever name he prefers, or to give a new one. One other point. - On page 161, under the genus Nototherium Owen, we read, “ Since this is the only known genus, its characters are the same as those of the family.” Now, no one knows better than the author of this e seriés of works, that this cannot be the case ! urse it is impossible for an author to keep pace with rapid additions to knowledge made in other countries. We only call etal here to the additional definitions of the Cre- odonta to be found in Professor Scott’s late memoir on that order, and refer to my own later studies, now in press, on the fauna of the Puerco Epoch. But we object to the slight value attached by Dr. Lydekker to the presence or absence of the scapholunar bone in this order (p. 305). Finally, we rise to two questions - 1Catalogue of Fossil Mammalia in the British Museum, Part V., con- taining Tillodontia, Sirenia, Cetacea, Edentata, Marsu upialia, Monotrem- ata, and Supplement. rede Richard Lydekker, B.A., F.G.S., ete- London. 1887. - Geological News. 165 of privilege. The first point is found in a foot-note on page one, viz.: “Cope (Vert. of the Tertiaries, p. 195), who regards the out- ermost cutting-tooth as an incisor, states that it is absent in Tillo- therium and present in Anchippodus, and that in the former there are seven and in the latter six cheek-teeth.” This paragraph com- mits me to two errors of which I am not guilty. Let “ outermost cutting-teeth ” be changed into innermost cutting-teeth, and I am correctly quoted. As to the cheek-teeth, I state that my informa- tion as to Tillotherium is derived from Marsh, and as to Anchip- podus I give the number with a question. The second point I wish to refer to is the assertion in a foot-note on page 379, that I state “that the inflection (of the mandibular angle) is absent in European forms” (of Peratherium). I here referred to the species called Oxygomphius by Von Meyer, some of which are true marsupials, but others are, according to Schlosser, Talpide. If there be an error, it is that of Von Meyer.—£. D. Cope. GEOLOGICAL News—GENERAL.—The “American Geologist” sends forth its first issue in January, 1888. It announced that it is to be a non-partisan publication, open to the properly-worded opin- ions of all, from the most powerful to the most obscure, and “ com- mitted to no theory whether of construction or obstruction.” Its editors and proprietors are Profs. S. Calvin, of Iowa University; E. W. Claypole, of Buchtel College; A. E. Hicks, of Nebraska State University; N. H. Winchell, of Minnesota University; Dr. Persifor Frazer, of Philadelphia; Dr. A. Winchell, of Michigan University; and Mr. L. O. Ulrich, of the Geological Survey of Illinois _ Prof. Claypole utters (American Geologist) a most distinct warn- ing to those who, merely because the wish is father to the thought, believe the supply of natural gas to be inexhaustible. Natural gas, oil, and salt-water are geologically connected, and, where the strata are arched upwards, usually collect in the order named. After a certain part of the gas has been drawn off the oil will rise, and lastly the brine. Many. once productive oil-wells are now 7 little more than brine wells, though their age is but twenty years. Gregorio Stefanescu, chief of the Geological Survey of Roumania, has issued a geological atlas of that country in four- teen colored sheets. Diluvial and alluvial strata are largely devel- oped, but crystalline rocks occupy the northern portion bordering on Transylvania. SILURIAN.—Messrs. U. P. and J. F. James publish in the Journal of the Cincinnati Society of Natural History a revision of 166 General Notes. the species of the Monticuliporoid corals of the Hudson River group. They admit two genera, Monticulipora and Ceramopora, the former with the sub-genera Dekayia, Constellaria and Fistulipora. DeEvontan.—Prof. Calvin (American Geologist) describes Strep- tindytes acervularie, a new species and genus of tubicolar Annelida from strata of the Hamilton period, at Robert’s Ferry, Iowa. CARBONIFEROUS.—Dr. G. J. Hinde, in a paper read before the British Association at Manchester, brings evidence in support of the organic origin of the “chert” in the carboniferous limestone series of the British Isles. He believes that the Irish cherts at least are derived from the accumulation of the skeletal elements of the siliceous sponges. Jurassic.—Prof. H. G. Seeley has shown, by superimposing a figure of the reputed clavicle upon the bone figured by Mr. Hulke as clavicle and interclavicle of Iguanodon (Quart Journ. Geol. Soc., vol. xli. pl. xiv.) that the supposed sutures are fractures, and that the supposed interclavicle has no existence, except as an ossifi- - cation posterior to the reputed clavicles. Prof. Seeley urges the analogy of these bones with the reputed pubes of crocodiles, and concludes that they are pre-pelvic. Prof. Seeley concludes, from examination of fcetal Plesiosauri found in a phosphatized nodule of Lias, that the Plesiosaurus was viviparous, and that the species in question, probably P. homo- spondylus, produced many young at a birth. Tertiary.—R. Lydekker (Geol. Mag., July, 1887) states that all the so-called fossil Alligators of the Old World really belong to the genus Diplocynodon, and since the crocodiles (C. palustris and C. sivalensis) which approach nearest to this genus in the structure of the cranium and form of the maxillo-premaxillary suture on the palate are confined to India, it becomes interesting to know whether the existing alligator recently described from China, may not show signs of affinity with Diplocynodon. Mr. Lydekker concludes that Crocodilus ehampsoides and C. toliapicus, from the London clay, are but the young and old indi- viduals of a single species, for which the original name of C. spen- ceri Buckland, should be retained. H. B. Geinitz identifies Nautilus alabamensis Morton, and N. lingulatus von Buch with Nautilus ziczag Sowerby, and places the form in the genus Aturia. The species is from the Tertiary of Alabama and Mississippi. Mineralogy and Petrography. 167 MINERALOGY AND PETROGRAPHY:! PETROGRAPHICAL News.—As the result of a recent trip through the southern extremity of Africa, E. Cohen? has succeeded in giving us quite a good deal of information regarding the Palæo- zoic formations of the Cape States. The pre-Devonian schists of the coast region have been treated in another place.* In the pre- sent paper the author confines himself to the various members of the Devonian and Carboniferous systems, and other formations overlying these. The most widespread rocks in this region are sandstones, graywackes and conglomerates. e Karroo formation (Triassic) Cohen divides into a lower, a middle and an upper series. The lower series comprises fragmental rocks with an occasional in- tercalated layer of an eruptive. The middle series is characterized by the number of layers of eruptives intruded between those of sedimentary rocks as well as by the number of dykes cutting across the latter. The eruptives, with a single exception, are plagioclase augite rocks. By far the larger proportion of these belong to the diabase family, many of them being olivine bearing. In the latter the peecilitic structure is frequently well marked. The diabases, quartz diabases, proterobase and diabase porphyrites, of both the intercalated layers and the dykes, are regarded by Cohen (as the result of careful analyses) as mere phases of the same magma. The single exception to the prevailing plagioclase-augite eruptives mentioned above is in the case of a dyke-cutting olivine diabase. The material of this bears a strong resemblance to mica syenite. At the points where the diabase layers come in contact with the interstratified sandstone beds the latter have been subjected to con- siderable alteration. The unaltered rock is an ochre-yellow, fine la sandstone, made up of quartz and colorless mica, besides a ittle iron hydroxide and earthy material. As it approaches the diabase it gradiially loses all traces of its bedding planes, and in it is developed a green chloritic mineral, whose nature was not deter- mined. Nearer to the eruptive the chloritic mineral increases in quantity, and in addition there is a development of biotite and _ a disappearance of the earthy material, which has probably gone to make up the biotite. In immediate contact with the diabase the sandstone has been entirely changed to a typical black hornfels. In it all the constituents have taken on a concretionary form. Analyses of the unaltered sandstone and of two typical altered phases teach that the change in the nature of the sedimentary rock is not due to any addition of diabase material. The dyke rocks produce but little alteration in the neighboring fragmentals. In 1 Edited by Dr. W. S. Bayley, Madison, Wisconsin. s Neues Jahrb. f. Min., etc., 1887, Beil. Bd. v. p. 195. Ib., 1874, p. 460. ? . ` 168 General Notes. one case, howeyer, where a dyke cut sandstone, it was noticed that biotite plates were developed parallel to the sedimentary planes of the sandstone, while muscovite formed perpendicular to these planes. The remainder of the paper is devoted to a discussion of the upper members of the Karroo formation and to the Pleistocene deposits, Another interesting paper is by K. Dalmer,’ on the quartz trachyte of Campiglia, in Tuscany. The glassy variety of this quartz _trachyte is a fine-grained gray rock, consisting of a glassy ground- mass in which are porphyritic crystals of sanidine, quartz, biotite and cordierite, with occasional crystals of plagioclase. The quartz grains all possess a rounded outline in cross section, and are surrounded by a zone of glass. In addition to the minerals mentioned above there also occur in this variety prismatic crystals of some member of the scapolite group light red garnets, apatite and zircon. In a felsitic variety scapolite is lacking. In the neighborhood of the quartz grains the felsitic groundmass of the rock is replaced by a zone of glassy material. The cordierite is less fresh and it is in the glassy variety, and in many instances is entirely replaced by pinite. In a third variety, occurring in dykes, the groundmass is completely crystalline. These dykes of grano-porphyritic trachyte were regarded by Lotti’ as quart porphyries, and as apophyses of a so- called granite mass which occurs about fifteen hundred metres distant from them. This mass was likewise examined by Dalmer, who, while he finds it to possess the characteristics of a granite porphyry, believes that its present condition is due to the conditions under which it cooled, and that the three trachytes and the granite porphyry are all portions of the same magma, which, from the nature of its surroundings, gave rise to rocks which from their structure and mineralogical composition must be classified under different heads. Professor ©. R. Van Hise? communicates some additional‘ notes on the enlargement of hornblende and augite in frag- mental and eruptive rocks. In the altered diabases of the Penokee- Gogebic Iron-Bearing Series crystals of uralitized augite are seen to have attached to them long acicular crystals of a very light green hornblende, which extend out from the uralite even into the sur- rounding decomposed feldspars. In other cases unaltered augite is surrounded by an almost sinuous sheet of amphibole. In both cases the crystallographic axes of the two minerals coincide. Dr. G. H. Williams® describes the alteration of ilmenite into rutile, in altered diabase from the vicinity of Quinnesec, Mich. Irregularly- shaped pieces of ilmenite are surrounded by a network of little prismatic crystals of rutile. 1 Neues Jahrb. f. Min., ete., epi ii., p. 206. s Atti della Societa Toscana. Vol. vii. .

Gerhard ' calls attention to the fact that most of the rocks described as soda-granites are really ordinary granites in which the proportion of sodium is little greater than is usually found in granites. The Ulfserud (Sweden) rock, however, appears really to contain a plagioclase approaching very near to albite in com- position. MINERALOGICAL NEws.—Dihydro-thenardite is the name given by Markownikow’ to a substance found ina thin colorless bed on the shore of Lake Gori, in the Gouvernement Tiflis, Russia. In com- position it is a sodium sulphate differing from thenardite and mira- bilite in appearance and its content of water. An analysis yielded 16.15 per cent. of water, corresponding to the formula Na, SO, + 2 H,O. It crystallizes in the monoclinic system.—Laist and Norton! report the occurrence of a new antimonide from near Mytilene, Asia Minor. The new mineral resembles silver in color and lustre. It is massive and brittle. Its hardness is 4.-5. and its specific gravity 8.812. Upon analysis it yielded: Cu = 73.37 per cent., Sb = 26.86 per cent., corresponding to Cu,, Sb, (breit- hauptite = Ni Sb, dyscrasite = Ag, Sb- Ag, Sb.)— A Barium manganite from near Austinville, Wythe county, Virginia, accord- ing to Mr. Walker,’ is of the following composition : Mod: RO BO SiO, (FeO.

Under the former are included the quartz- porphyries, the quartz-free porphyries and keratophyres, the porphy- rites, the augite-porphyrites and melaphyres, and the picrite- porphyrites. We miss here the elæolite porphyrites, which have been relegated to the questionable group of dyke rocks, and the quartz-porphyrites, which have been merged into the porphyrite family. The melaphyres are now members of the augite-por- phyrite family, and the keratophyres have found a home among the quartz-free porphyries. There are nowhere as sharp distinctions made between rocks of different mineralogical and chemical compo- sitions as were found in the first edition of the Mussige Gesteine. The classification has become somewhat more complicated than the old one, but at the same time it seems more reasonable in the light of recent investigations. Among the neovoleanic rocks we find the liparites and pantellerites, the trachytes and quartz-free pantellerites, the phonolites, the dacites, the andesites, the basalts, the tephrites and basanites, the leucite rocks, the nepheline rocks, the melilite rocks and the limburgites and augitites. We here also miss a few familiar groups. The augite andesites are classed with the ande- sites. The tephrites and basanites have been united into one family. The entire group of glassy rocks has been eliminated, and the indi- vidual members have been included ‘among those families of the neovoleanic rocks with which they are genetically connected. The discovery of a triclinic potassium sodium feldspar by Férstner’ in the sodium-rich liparites of the island Pantelleria has resulted in the separation of the old liparite family into two subfamilies— the liparites proper, containing sanidine, and the pantellerites containing anorthoclase as their principal feldspathic constituents. Each family among both the palæovolcanic and the neovoleanic effusives is composed of numerous species or varieties, each one of in the book be interesting. 1 Zeits. f.

THE Grass FLORA OF THE NEBRASKA PLAINS.—The plains of Nebraska were originally covered in great part with various small grasses to which the common name of “ Buffalo grass” was applied. The true Buffalo grass (Buchloé dactyloides Engelm.) formerly extended eastward to or nearly to the Missouri River, but now it is rare east of the 100th meridian. On the curious depression near the city of Lincoln, to which the general name of “Salt Marsh” has been given (although it is in no sense a marsh), small patches of Buffalo grass may still be found. It is a peculiar grass, and when one has once noticed a patch of it, he will at once be able to recognize it even at a distance. It invariably grows in patches, and in each patch scarcely anything else grows. It does not intermingle with other species but holds complete possession of the soil, forming a dense mat which chokes out all opposition. Northwestward, up the Elkhorn Valley, Buffalo grass does not appear in any quantity until very nearly the 100th meridian is reached, although much of the land is still uncultivated. Going westward from Lincoln, small patches are to be seen in Clay county (98th meridian), and from this point it increases as one goes up the plain above the 2,000 ft. line. In the Loup valley, however, Buf- falo grass is not abundant, while in the Republican it is very com- mon, In the western portion of the State, from the Lodge Pole Creek on the south to the White River country on the north, it is still very abundant. ramma (Bouteloua oligostachya Torr.) is still found throughout the State, although it is by no means abundant in the eastern two- thirds. It is often called Buffalo grass, and from it a short hay is sometimes cut in the latter part of summer. Its relative, the Muskit or Mesquite grass (Bouteloua racemosa Lag.), has a still wider distribution, extending eastward into Iowa and Illinois, and westward across the plains. In the far-west, above the altitude of 3,500 feet above the level of the sea, another of the grasses of the plains proper appears. It resembles Buffalo grass so closely in general appearance, that it may well bear the name of False Buffalo grass (Munroa squarrosa Torr.), although it belongs to an entirely distinct genus. Upon the saline and alkaline soils Salt grass (Distichlis maritima Raf.) grows in abundance. I have seen it upon all parts of the great Nebraska plain. The grasses which are most noticeable in nearly all portions of this region are the Blue Stems or, as they are sometimes called, the Blue Joints. The great Andropogon provincialis Lam, and its smaller relative Andropogon scoparius Michx. oceur in company with Chrysopogon nutans Benth., the latter often called Bushy Blue 1 Edited by Prof. Chas. E. Bessey, Lincoln, Neb. 172 General Notes. Stem. Throughout all parts of the State they occur in company, and they are common and abundant in nearly every locality. How- ever, in the eastern part of the region they grow taller, and are more inclined to entirely cover the ground. The first-named often attains a height of from six to eight feet. In the western part of the region Andropogon saccharoides Swz., a feathery topped species, occurs along with the preceding. n the eastern counties Wheat grass (Agropyrum glaucum R. & 8. ) appears in little patches, which are plainly noticeable on account of their glaucous green color. As every botanist knows, this spe- cies bears a remarkable resemblance to Quack grass (Agropyrum repens Beauv.), but it is not as much inclined to spread by its under- ground rootstocks as its eastern relative. As we go westward this Wheat grass increases in abundance, and by the time we reach the altitude of 3,000 to 5,000 feet, it is one of the most valuable of the hay grasses, and is relied upon very largely for forage by the farm- ers and stock growers. Two other grasses are very common upon the plains, viz., Hato- nia obtusata Gr. and Koeleria cristata Pers. They occur every- where upon the drier lands, and are emphatically Prairie grasses. With them we find very commonly Sporobolus asper Kth., a late- growing species, which remains standing all winter long, with leaves wrapped around its partly enclosed fruiting panicle.— Charles E. Bessey. Sotms-LAvuBAcH’s PAL#OPHYTOLOGIE.—A few months ago this na aed work was brought out by Arthur Felix in Leipzig. Its seope may be indicated by the following summary of its con- tents: Thallophytes and Bryophytes receive 19 pages; Coniferæ, 33 ; ycadeæ medulloseæ, 20; Cordaiteæ, 19; Ferns, 53; Lepidoden- dreæ, 48 ; Sigillarieæ, 23: Stigmaria, 32; Calamariez, 50; Sphe- nophyllez, 13. Fifty or more pages are devoted to smaller 'zroups, and to the discussion of genera of doubtful affinity. Forty-nine wood-cuts add materially to the value of the volume. BorantcAL Work IN New York.—The reception of two reports from the State botanist enables us to note the progress of systematic botany in New York. The statement of the work of the botanist for 1885, published in the Thirty-ninth Annual Report of the New York Museum of Natural History, 1886, includes descriptions of many new species of fungi, among which are seven species of Agaricus, one of Russula, two of Boletus. The New York species of the genera Pleurotus, Claudopus and Crepidotus are fully described. In the Bulletin of the New York State Museum of Natural His- tory, Vol. I., No. 2, which bears date of May, 1887, Mr. Peck describes fifty-four species of fungi, among which is an interesting Botany. 173 Morchella (M. angusticeps), which is apparently related to M. conica Pers. Descriptions of the New York species of the genera Pax- illus, Cantharellus and Craterellus follow in the usual lucid style of the author. Measurements are give (unfortunately in fractions. of an inch), and good notes as to habits and habitats. e New York Pyrenomycetous fungi are listed according to: Saccardo’s nomenclature, and for convenience the former names are given in a parallel column. The Bulletin closes with a monograph of the New York species of Viscid Boleti. Fourteen species are carefully described, two of which (B. subluteus and B. americanus) are new to science. Two good plates accompany the Bulletin.— Charles E. Bessey. Tue Deatu or Dr. Asa Gray.—On the 30th of January, Dr. Asa Gray, the venerable botanist, passed away, after an illness of two months. e was born in Oneida county, N. Y., November 18, 1810, and was consequently a little more than 77 years old when he died. Although spared to such an advanced age, with undi- minished mental and bodily vigor, which enabled him to continue work into his 78th year, yet all the world of science will mourn his. death, regretting that so great and kind a master should be taken away. A longer notice will appear later. BoTANICAL News.—The November-December number of Hed- wigia contains a heliotype of the lamented Georg Winter, with a sketch of his life and labors. r. C. Sanio now assumes editorial (= Nuphar sagittifolia Pursh.); Castalia pudica Salisb. (= Nym- phea odorata Ait.) In other words, our Nuphars are hereafter to 174 General Notes. be Nymphzas, and our Nympheas hitherto are hereafter to be known as Castalias. In the January Gardener’s Monthly the suggestion is made that certain species of Cactus may become of value as fodder plants for domestic animals. The January Torrey Bulletin contains Studies in Typhacez, by Thomas Morong; New and Little-known Grasses, by F. L. Scribner, and New West- ern Grasses, by George Vasey, besides other articles of interest. Professor James suggests the name Anthophyta for Phanerogamia —a very good name too. The January Botanical Gazette con- tains a portrait of Dr. W. Pfeffer, of the Botanical Institute at Tiibingen, with a sketch of the institute, illustrated with a plan and views. The index to Vol. XII., which accompanies this num- ber, is a model among indexes. Certainly no reader of the last year’s volume of the Gazette can complain, in Carlylean phrase, of its “ indexlessness.” ZOOLOGY. FUNCTIONS oF INVERTEBRATE Orocysts.—Professor Yves Delage has been performing some experiments with a view of as- certaining the functions of the so-called ears of invertebrates. His results (Archives de Zool. gén. et Expérim. v. 1886) go to show that besides auditory capacities, they possess regulative faculties. When the octocysts were destroyed, the animal could not regulate its movements. This he shows is not due to the injury to the nerve, because the extirpation of the eyes did not produce disorder in the movements. His experiments were mostly upon Crustacea and Cephalopods: Parasitic Rorrrers.—The marine rotifers which are parasitic upon the curious Crustacean, Nebalia, are grouped in a amily Seisonide and the species of these found in the Bay of Naples have recently been studied by Dr. L. Plate. He adds to the two genera before included (Seison and Saccobdella) a third, Paraseison, with four new species. In these the trochal discs have been re- duced and may be represented by a few sensory sete ; the intestine terminates cecally in either six; the reproductive glands are at the sides of or above the intestine ; the tail has no sucking disk, but on the rounded extremity open the glands which serve to attach the ectoparasite to its host. The paper may be found in vol. vii. of the Naples Mittheilungen. MEDITERRANEAN SYNAPTIDZ.—Dr. R. Simon contributes to the Naples Mittheilungen (vii. p. 272, 1887) an account of the Mediterranean Synaptide, embracing the species digitata, Zoology. 175 inhærens and hispida. These forms live on, not in the sand, in this not resembling our American, ©. girardi. There are some detailed accounts of the development of the calcareous plates of these as well as other Echinoderms. The author also describes a new species .of Chirodota (C. venusta), the first recorded from the Mediterranean. BEDDARD ON EARTHWORMS.—The literature of the Lumbri- cidæ is rapidly assuming frightful proportions, so that none but the specialist can keep track of it. Mr. F. E. Beddard has re- cently added much to our knowledge of these forms. In the Pro- ceedings of the Zoological Society (p. 154, 1887), he describes as new Thamnodrilus gulielmi from British Guiana. This genus re- sembles Anteus by the absence of dorsal pores,in having a single pair of spermathecæ in the seventh segment, and in position of the nephridial opening. In Thamnodrilus, however, the clitellum is much shorter, and the differentiation of the nephridia into three series is another character separating them. Later in the same volume (p. 544), he describes Cryptodrilus fletcheri (n.sp.) from Queensland. It possesses calciferous glands and in its nephridia it is much like Mierocheta but their orifices vary in position from segment to segment. ‘The seminal vescicles occur in segments 9 and 12, but not in the intermediate segments. A third paper (Jour. Anat. and Physiol. xxii, October, 1887) deals with the structure of the ovum in Hudrilus sylvicola from British Guiana. Here the ovary is enclosed with muscular walls, the muscles being continuous with those of the oviduct, and its interior is divided by trabecule into separate compartments, which are packed with ova and germinal cells. The history of these is traced, the most notice- - able feature being the metamorphosis of some of the germinal cells to form an epithelial cap on one*end of the ovum, while others degenerate and form a fibrous looking, and more or less uid mass around the ovum. This degeneration may have nutri- tive functions, but Mr. Beddard suggests its analogy to the liquor folliculi of the mammalian ovary, a view which receives some sup- port from the fact that the most nearly ripe ova are not always found nearest the entrance to the oviduct. ZOOLOGICAL Nores. — Prorozoa.—Mr. H. B. Brady cata- logues the recent species of Foraminifera, occurring in Great Britain in the December number of the Journal of the Royal Microscopical y. The classification adopted is the same as that used in the Reports of the Voyage of the “ Challenger.” 267 species are enumerated, but one (Zrochammina robertsoni) being regarded as new. The genus Haliphysema is regarded as a Foraminifera. A. C. Stokes has recently described some more American Dr. Infusoria, In the American Mon. Micros. Jour. (p 141) he adds — * 176 General Notes. to our fauna Anthophysa stagnatilis Hexamita gyrans Chloromonas, Balanitizoon gyrans, Gerda vernalis Rhabdostyla vernalis, R. cheeticola, Vorticella similis, V. vernalis, V. parasita, V. conica, Epistylis tincta, and Lagenophrys obovata. In the Annals and Magazine of Natural History for August, 1887, he adds: Onychodromopsis flexilis (n. g. et sp.) Tachysoma agile (n. g. et sp.) T. mirabile, T. parvistylum, Litonotus vermicularis, Loxodis magnus, Oxytricha biforia, O. hymenostoma, O. acuminata, O. caudata, Histrio inquietus, H. complanatus, Euplotes variabilis, and Chilodon voraz. e last species feeds voraciously upon diatoms, some of which were actually . . longer than the infusorian. Podarcella is the name given by Girard to a stalked Rhizopod allied to Arcella which occurs in the sea near Fécamp. The stalk is about one and one-half times as long as the lorica. orms.—The veteran, P. H. Gosse, describes twenty-four new British rotifers in the December number of the Journal of the Royal Microscopical Society. The specimens were from both fresh and salt water. Those interested will find a valuable article on the anatomy and histology of the Aphroditaceæ, by Dr, E. Rhode, in the second volume of Schneider’s Zoologische Beiträge, and one on the anatomy and histology of Wunice, by E. Jourdan, in the second volume (seventh series) of the Annales des Sciences Naturelles. Jourdan thinks he has founed the terminations of the nerves in the muscles ; does not regard the “ giant nerve fibre” of the vent cord as nervous but rather as a supporting structure ; describes the eye, found no glandular structures in the digestive tract, and de- scribes the segmental organs, pedal glands, and pigment organs. CrusTAcEA.—It is usually believed that hermit-crabs appro- priate dead shells for their homes but Mr. Lucas, in the Transac- tions of the Royal Society of Victoria, states that he witnessed a hermit attack a living Fasciolaria and little by little tear it in pieces, leaving the shell at last entirely empty. He also recalls the fact that, at least in tropical waters, the shells occupied by hermit- crabs have a fresh appearance, and he thinks that the crabs depend upon living shells rather than dead ones to form their homes.

Bey- erinck has published a paper regarding the growth of the gall produced by a saw-fly, Nematus capree, on Salix amygdalina. This article appears to be an important supplement to the observa- tions of Adler, published some years ago. I have not seen the sewn paper by Beyerinck, and therefore quote from an abstract of it. “ The production of the gall is undoubtedly due to the matter se- creted by the poison-gland, which is, consequently, homologous with the poison of Hymenoptera aculeata; when the insect does not deposit an egg in the wound which it makes, the quantity of albu- minous matter poured out by the vesicle is always less than when an egg is deposited ; by careful observation it is possible to assure oneself that the size of the gall is always proportional to the size of the wound and the quantity of albuminoid matter introduced. By an experiment, in which the deposited egg was punctured by a fine needle, it was shown that the gall is due to the parent and not to the egg; but, of course, in such a case’ the gall remains small; neither the egg nor the larva are necessary for its production, though their presence exercises a certain influence on the regularity of the . development. ” “ The author has endeavored to discover whether there is any persistent alteration in the protoplasm of the plant or not. If we Suppose that the substance implicated in the substance of the gall is like the protoplasm of the plant, a living body able to grow indefin- itely, or a substance which impresses a persistent modification on the protoplasm of the plant, we ought, if we should succeed in pushing the development of the gall as one of its parts beyond the stage at which it ordinarily stops, to find that the characters of the gall remain invariably the same. If, on the other hand, the gall-form- ing matter can not either grow itself nor form a new protoplasm capable of reproduction, we ought, under similar circumstances, to find the characters of the organ, whence the gall was developed, - 1 This department is edited by Prof. J.

Experience has shown that the second is the condition which it obtains ; a normal leaf modified by the gall-forming material grew into a normal leaf, and a root into a root. “ The galls of Nematus are possessed of extraordinary vitality ; those of N. capree are found living long after the leaf is dead; N. viminalis, which is found on Salix purpurea, exhibits really remark- able properties ; although abandoned by their inhabitants at the beginning of autumn and being surrounded by damp mould during the winter, they not only remain perfectly turgescent, but some of them are able, in the following summer, to begin a new life. Galls cannot be inherited. The specific material secreted by Nematus capree—and what is true of it is probably true of other forms—is an albuminoid substance which acts as an enzymatic body.” HOMOLOGUES OF ARACHNID APPENDAGES.'—Herr A. Lendl has studied the development of Epeira diademata with reference to the much-discussed problem of the homologies of the appendages. The general conclusions of his investigations are as follows: (a) bes first pair of appendages represent antenne ; this is suggested by eir origin, position, motion, jointing, and innervation from the supra-cesophageal ganglion. (b) The small tubercles under the upper lip resemble mandibles in their origin and in the connection of their ganglia with the cesophageal ring.

While the purpose of the work is the same as that of Kélliker’s Grundriss, viz., for medical students, it presents certain admirable features not met with in the just-named classical and beautiful work of the venerable savant who holds the chair of anatomy in the Uni- versity of Würzburg. The wonderful and accurate figures which adorn the pages of Kölliker’s writings on embryology are no less attractive than the luminous style in which his expositions are couched. But in the Grundriss only two types are appealed to— viz., the Bird and Mammal, in order to unravel the intricacies of embryology as applied to the needs of the medical man. With larger opportunities for study, and as the author of many classical contributions to the embryology of the lower types as well as through studies upon the maturation and fertilization of the egg in various types, Dr. Hertwig approaches his subject equipped with a range and profundity of knowledge not surpassed by any recent writer. His studies in experimental embryology—during which e, in association with his no less distinguished brother, Richard Hertwig, reached results of the most startling significance in caus- ing multiple impregnation of a single ovum by previous immersion in dilute solutions of narcotics or anesthetics—are still fresh in the minds of specialists. His no less interesting studies upon the phenomena of fertilization of the egg in echinoderms entitle him to rank amongst those pioneers of modern embryology who have given us a basis for a rational theory of heredity, founded, not upon abstract speculations, but upon carefully observed facts. Through the observation of these facts by Hertwig and others it has been possible also to enunciate the doctrine of the continuity of germinal plasma and the laws of geotropy of the ovum; while his Ceelom theory, published in 1881, has already borne fruit in the admirable English treatise of Professor Haddon, which was noticed about a year since in this journal. This cælom theory supplements that of the now universally accepted gastrula, and makes it possible to present the facts of embryology in such a manner as to render their comprehension easy and significant. While the protective coverings of ova—i.e., the primary and secondary investments of the eggs of various types—have not been as fully discussed as they might have been, and the existence of a third or tertiary system of deciduous investments, derived from the segmenting oyum itself in the higher forms, has not hgen perhaps clearly recognized, on the whole the work commends itself as the most satisfactory manual which has yet appeared for. those who have not the time to enter upon a special course of study in this branch of scientific discipline. The author has succeeded, in the compass of two hundred pages, subdivided into thirteen chapters, in presenting in a novel and in- teresting manner what it is essential that the young naturalist, or medical student should know of the sexual elements; the matura- Embryology. 181 ably give us important additional light. he manual of Dr, Hertwig will doubtless fill a lene want ; and it is to be hoped that it will be made accessible to the English- reading student through a translation by some capable person. As an aid in understanding many questions in pathology, physiology, the structure of the brain and mechanism of the nervous system, this little work will undoubtedly be found to be of great ogee lightening the burden of the overtaxed medical student in his 182 General Notes. efforts to master the intricacies of the anatomy and histology of the adult human body.—J. A er Mr. O. P. Hay’s OBSERVATIONS ON THE BREEDING-HABITS or AmpHiuMA.—In the last number of this journal (page 95) an tie E was given of how the Amphiuma coils herself about her The description of the eggs and embryos is so strikingly Tike ‘that of Ichthyophis glutinosus, a limbless, worm-like salamander,—the development of which has been worked out by the Sarasin Brothers from material collected in Ceylon,—that it is very important to call attention to this resemblance and its probable sig- nificance. Within about two years Professor Cope called attention to the fact that the structure of the skull of the Cecilians and of Amphiuma showed that these two forms were related. It now turns out that the females of these two types have the same habit of coiling them- selves about their ova, which in both cases are laid in strings, with constrictions separating them, somewhat like a string of beads, the individul ova in both being ‘also of about the same size. This confirmation of Professor Cope’s conclusions as to the taxonomic relations of these two types is a very interesting instance of the way in which embryological data may become available. It may also be noted that in some of the Cæcilians there are three plumose or feathered branchie arising close together, and saa pathy similar to those described by Mr. Hay in the young of Amphiuma It is to be hoped that that gentleman will be good enough to somewhere publish carefully-drawn figures of a. eda! of Amphiuma, as wellas of the embryos.—J. A. Ryder ARCH XZOLOGY AND ANTHROPOLOGY. ! e The Anthropological Society of Washington has renewed and enlarged its sphere of usefulness. It has taken a new departure, in fact three new departures. It has elected a new president; it has become an incorporated society, and it has commenced the pub- lication of a quarterly journal under the direction of an editorial committee. The name is American Anthropologist, the first num- ber appearing January, 1888. The typography is in the highest order of the art. The article on the Chane-abal (four-language) tribe and dialect of Chiapas, by Dr. Brinton, Professor in the Uni- versity of Pennsylvania, being done as to excite the admiration of all interested in the typographic art. The contents of the first number, in addition to the article just mentioned, are “The Law 1 This department is edited by Thomas Wilson, Smithsonian Institu- tion, Washington, D. C.

A future number will contain an article “ From Barbarism to Civilization,” by Major Powell, Director of the U. S. Bureau of Ethnology, a continuation of his history of man from savagery to barbarism. Among the papers read before the society, of great value, and which we hope to see published ere long, was the prayer of a Nav- ajo shaman, by Dr. Washington Matthews, U.S. A.; a linguistic map of North America, by Mr. H.W. Henshaw, of the U. S. Bureau of Ethnology, in which the author showed the existence, the con- dition and the relationship of the various Indian languages and dialects in all North America. The discussion of the Nephrite ansston, by Profs. Clarke and Merrill, was also interesting and valuable, Success and of practical value would require the co-operation of European anthropologists. Without it the proposed congress might be but slightly more important than the meetings of the section of anthropology in the Association for the Advancement of Science. If the co-operation and promise of attendance of the anthropologists of Europe has been secured, the success of the project is assured. b An attempt was made to hold such a congress at Athens, Greece, ut it failed, owing to want of co-operation combined with the un- settled state of the country.

Their claim could be made with great show of right and would scarcely be ignored. It would be a source of regret if these two commendable projects should be made to interfere with, or nullify, the good that each might do. 7 CRIMINAL ANTHROPOLOGY.—The importance of the subject of Criminal Anthropology has not been properly appreciated in our country. I doubt if any branch of the social history of man can be studied with such practical benefit to the whole people. Laws are still passed, and courts sit in its administration, as in olden time, the theory being to punish the criminal, not out of revenge, but for the prevention of crime. But in this principal object, the prevention of crime, the world has changed but little, and it is doubtful if it has improved any. There have surely been improvements in modern times in criminal jurisprudence, but they have been rather in matters of detail, pleading, practice, etc, In- dictments are more simple and direct. The disqualifications of jurors are lessened, many matters of mere form have been brus aside, all tending to the presentation of the truth to court and jury. The examination of the defendant as a witness is fast becoming a necessity. But with all this the science of criminal biology has received but slight attention from lawyers or law-makers. This, _ when done, must be done by anthropologists. The anthropologists of Europe are more interested in this work than are we of the | United States. They have taken the initiative. An international convention met in Rome in the autumn of 1885, and devoted a week exclusively to criminal anthropology. In France the ques- _ tion of the recidivists presses hard upon the attention of the govern- ment. I saw a man stood up in the dock who had been then con- victed of crime forty-two times. The Island of New Caledonia, in the South Pacific, serves as a prison for those who have been con- victed of felony more than thrice. The Anthropological Society of Paris has taken up the subject and is now studying it seriously. By a law of France, all executed criminals, possibly only those of Paris, are delivered to this society, and in its Musee Broca are now to be seen all their articulated skeletons with a bit of cork ars the void made by the guillotine in the cervical vertebra. I fee that I can speak on this subject with more than ordinary authority. I have practised at the bar as a lawyer with reasonable success for twenty-five years, not so much, however, in the criminal branch. During my six years’ consular life abroad there arose cases by which my attention was turned to the criminal system under the Code Napoleon. I was a member of the international congress for the reform and codification of the law of nations, and in my studies Archeology and Anthropology. 185 of later years I have mixed, to a great extent, the sciences of law and anthropology, and I cannot too much exalt the investigation and study of criminal anthropology. But it should be practical as well as theoretical. The lawyer and legislator should be brought into communication with the anthropologist. Their co-operative labors would serve to elucidate the subject in a scientific as well as a prac- tical manner, and would result in the lessening of crime and the general improvement of the body politic. A move in the right direction has been taken by the New York Academy of Anthro- pology at its meeting, January 3, 1888. The subject was divided into two sections, and the program of questions suggested for dis- cussion was as follows: CRIMINAL Brotoay.—1. What categories of criminals may we distinguish ? and what are the fundamental characteristics, physical and psychical, which they display ? 2. Is there a general bio-pathological constitution which pre- disposes its subject to the commission of crime? how does it origin- ate, and what form does it assume? hat is the proper classification of human actions, based on the affections which give rise to them? What effect does the edu- cation of the moral nature have upon the passions, and, indirectly, upon crime? : - Does the number of suicides stand in inverse ratio to the number of homicides? 5. Epilepsy and moral insanity in prisons and insane asylums. — Malingering among the insane. 7. The utility of a museum of criminal anthropology. 8. The influence of atmospheric and economic conditions of crime in America. CRIMINAL Socioto¢y.—1. Should the theories of criminal an- thropology be embodied in the revision of the penal code? and why? 2. The function of the medical expert in judicial procedure. 3. The best means for securing indemnity from crime. 4. The best means of combating relapses into crime (reci- divism), 5. Crimes of a political character. | 6.

A. C. Butts and Hon. Geo. H. Yeaman, of the New York Bar; Judge Calvin G. Pratt, of Supreme Court, Brooklyn, N. Y.; Foster L. Backus, of Brooklyn; Pro ae J. Reese, of University of Pennsyl- Vian William’ J. Mann, Es sq.; E. P. Thwing, M.D.; Prof. Moritz Benedict, of Witenes and others. The Bar Association of the District of Columbia has proposed an international or interstate law congress, to be held in the city of Washington, on the 22d of May, 1888, to which shall be invited representatives of all other bar associations, judges of courts, pros- ecuting officers, and lawyers whose eminence in their profession en- title them to that recognition. Ido not know whether this will result in a permanent organization or not. But if so, I would sug- gest and strongly urge that it should have a section devoted to criminal anthropology ; and that anthropologic societies and con- gresses should do the same. By this means professional lawyers who are amateurs of anthropology, and professional anthropologists who may-be amateur lawyers, would have opportunities for the accomplishment of great good in their respective sciences. MICROSCOPY .! GERLACH’s EMBRYOSCOPE.—The embryoscope, devised by Dr. Gerlach, supplies a great and long-felt desideratum in experimental embryology. It is a mechanism for closing hermetically, a circular opening, made with a trepan, in the shell of the hen’s egg; and it serves the purpose of a window, through which the living ‘embryo np be directly observed, and its development followed from day to da The instrument consists of two parts : A mounting-ring (Aufsatzring) to be firmly cemented to the tel. 2. A key- piece with glass front, which screws into the ring and closes it air-tight. In the Cut. A represents the embryoscope in perspective, and B, in section. The metallic mounting-ring is 1} mm. thick, an a lumen 2 cm. in diameter. The lower edge (Ar) is bevelled and saddle-shaped so as to fit the equatorial surface of the egg, while the upper edge is flat. From the outer surface of the ring, two Savaro oaraid bars (Z) project in opposite directions. On its inner surface, a little above the lower edge, is a diaphragm (Md) * Edited by C. O. Whitman, Milwau 2 Anatom. Anzeiger, II, Nos. 18 and Hs “i887, p. 583. Microscopy. 187 with an opening 13 mm. indiameter. Resting upon this diaphragm, and corresponding with it in size and shape, is a second diaphragm of thin wax-cloth (Wd), which serves as a packing-washer for the ey-piece. The key-piece of the embryoscope consists of a low, metallic cylinder, closed by a disk of glass (G), which represents the window that is to cover the artificial opening in the shell. The upper part of the cylinder expands peripherally to form a rim with a milled edge. This rim has two notches opposite each other, into which fit the arms of a small wrench, by the aid of which the key-piece can be tightly screwed down. There is also a short, narrow, verti- cal canal (Vo) or vent, the lower end of which must open in the middle of the key-piece ring. The accessory apparatus required in the use of the embryoscope consists of (1) a trepan, (2) a guide-ring for the same, (3) a metallic Jork, and (4) the key or wrench before mentioned. _ The above-named pieces, together with a punch to cut wax-cloth ms, and six embryoscopes, may be obtained from Reiniger, a F edge of the diaphragm. e guide-ring for the trepan has the same construction as the 188 General Notes. key-piece, except that it has no glass disk. It serves to steady as well as guide the trepan during the process of cutting. The fork has two notches at the ends of its prongs, fitted to receive the two bars of the mounting-ring. When adjusted to the bars, the fork serves as a means of holding the embryoscope securely, while screwing or unscrewing the key-piece. ° The wrench, the use of which has already been explained, is similar in construction to the wrench used for mathematical instruments. e mounting-ring is fastened to the egg by means of a cement consisting of two parts of wax and three parts of colophonium. The cement is hard and brittle at the ordinary room-temperature, but becomes soft and kneadable when held in the hand for a few moments. After warming the mounting-ring over a gas or a spirit lamp, a roll of the softened cement is pressed into the space which must be completely filled between the lower face of the diaphragm and the lower edge of the ring. As soon as the ring becomes sufficiently cool, it is pressed firmly to the equatorial surface of the egg, and the excess of the still soft cement, which is thus forced outward and inward beneath the ring, should be removed before it becomes brittle, by the aid of a small, sharp- pointed blade. In order to avoid injuring the blastoderm, which might occur if the hot ring were fastened to the shell directly over it, it is best to fix the ring to the side rather than the top of the egg- After the ring has been securely fixed and the superfluous cement ‘removed, the exposed edges of the remaining cement, seen beneath the lower edge of the ring and the inner edge of the diaphragm, must be covered with a coat of an alcoholic solution of yellow shellac. This may be applied with a small brush, care being taken to cover the cement completely, and as little of the egg-shell as: possible. After the shellac has dried, a process which is completed in twelve to fourteen hours in the open air and in six hours in the incubator, the shell may be trepanned. Antiseptic precautions are required in opening the _ An oblong porcelain trough or glass dish is first filled with a 3% solution of carbolic acid, and in this are placed the instru- ments to be used in the operation: a glass rod, a medium-sized brush, small shears, forceps, the trepan, and the guide-ring. Before using, these instruments are dried with carbolized cotton, and after using returned to the dish of carbolic acid. r washing the hands in dilute sublimate or carbolic acid, & perfectly fresh egg is painted with the three per cent, solution carbolic acid, and then dried with carbolized cotton. The small end of the egg-shell is then cut out with the shears, and the thick white poured with the aid of the glass rod into a clean dish, leaving the yolk and the thinner white in the shell. The white is to be Microscopy. 189 used in screwing in the key-piece, and must therefore always be prepared beforehand. After these preparations, the egg to which the mounting-ring has been cemented is disinfected in the manner above described, and placed in an egg-carrier with the ring uppermost. The inside of the ring is then brushed with carbolic acid, which is shaken out after one or two minutes and replaced by a 4% solution of common salt, which is also allowed to remain from one to two minutes, and then completely removed by means of carbolized cotton. The guide-ring is now screwed in, and the egg trepanned from the side, in order to avoid injuring the blastoderm. The egg is next plaeed with its opening upward, and the guide-ring removed. When the trepan is withdrawn, the excised piece of shell often comes with it, and sometimes the underlying shell-membrane. If this is not the case, the two pieces must be removed separately by the aid of the pincers. Care must, of course, be taken not to injure the blastoderm and the zona pellucida. . The thin white, which was left with the yolk in the shell, is allowed to flow over the glass rod upon the exposed blastoderm until the ring is filled, care being taken to avoid air bubbles. The wax-cloth diaphragm is next taken from the dish of carbolic acid, dried in blotting-paper, drawn through the thick white, and inserted in the ring in close contact with the metallic diaphragm ; and then the key-piece, previously washed with carbolic acid and dried with carbolized cotton, is slowly screwed down. The superfluous white 18 thus slowly forced out through the vent (Vo), until the key-piece reaches the diaphragm and closes the vent.

If it is placed upward, the respiration of the embryo is hindered. The embryoscope can be turned up at any moment, and kept upright for five minutes at a time without injury to the mbryo. With 2 little practice, the whole process of arming an egg with the embryoscope may be completed in from six to eight minutes. The embryoscope is well adapted for purposes of class-demon- stration, for investigating the growth of the various parts of the embryo, and the physiological processes during embryonic life, as the action of the heart, movements of the body, etc. It is indis- pensable to him who would study the effects of external agents upon the embryos of warm-blooded animals; and must be of great service where it is required to determine the precise stage of devel- opment before removing the embryo from the egg. It has been found useful in studying the formation of double embryos. Fene- strated eggs have been successfully incubated up to the thirteenth day, and it is probable that under favorable conditions the embryos of such eggs would reach maturity. On the fifth day, it is still easy to bring the embryos under the window. On the sixth and seventh days, it is more difficult. At this period the change in the position of the embryo, which requires from five to ten minutes, should take place in the incubator, After the eighth day, the embryo cannot be brought under the window. If it be necessary to determine whether such an egg or an older one still lives, we have only to leave the egg for several hours in the incubator with the window directed upwards a little, after which, by strong reflected light, one may readily see the blood circulating through the channels of the vascular area.

MORPHOLOGY OF THE LEGS OF HYMENOPTER- OUS INSECTS." BY PROF. A. J. COOK, AGRICULTURAL COLLEGE, MICHIGAN. ’ ACCORDIN G to our modern philosophy regarding the origin and development of animal organs and organisms, we should look at such organs as are much used in the animal economy to find extremes in modification. Thus among mammals the teeth are KY @.1. oar Paper was read before aaa Association for Advancement ence, in August, 1887, at N. Y. meeting. 194 Morphology of the Legs of Hymenopterous Insects. most modified and very important in systematic mammalogy. For like reason the ornithologist looks to bill and feet in his study of families and genera, With the laws of variation and adaptation before us, we should expect to find modification carried to extremes ‘among Hymenopterous insects. The life functions of these insects are so wonderful and varied that a maximum differéntation of or- gans and structure is required for their execution. The chief tools used by these Hymenopterons are the legs and mouth organs, and it is to the former that I invite attention. Let us consider the anterior or prothoracic legs of the honey-bee. We first notice (Fig. 1) a strong and interesting modification in the basal tarsus and tibial spur, which modification is known as the “antenna cleaner.” At the base of the first tarsal joint and in the angle between it and the tibia is a short, hollow semi-cylinder. The concave surface of this cavity is smooth except at the outside margin, where there are from seventy-eight to ninety projecting hairs, which under the microscope remind one of the villi of the small intestines of mammals. These teeth, like hairs, projecting as a fringe, form a most delicate brush. The tibial spur is so modified as to resemble a very short handled razor, the blade of which is for a wide space facing the tarsus, a most delicate membrane, and this blade forms a sort of lid to the cavity just described. When the leg is straight this lid barely reaches the cavity ; but when the first tarsus is flexed upon the tibia it serves as a cover to the cavity and really closes it. The peculiar structure is found in both sexes and in the abortive females or workers of social bees, in all other bees, in all wasps so far as I have examined, in the Mutillide, Formicide in ants, in all the families of parasitic Hymenoptera except the Chalcids, while in the Cynips, Cynipide, Saw flies, Tenthredinide, and horn-tails, Uroceridee, we find it nearly or quite absent. We find the “antenna cleaner” in all species of bees—Apide— even in the curious species like the male of Megachile (Fig. 2), where the whole ante- rior leg is remarkably modified. Inthe bumble- bees species of the genus Bombus we find the an- tenna cleaner almost Morphology of the Legs of Hymenopterous Insects, 195 exactly like that of the honey-bee, except the part which I have termed the blade, in the modified tibial spur has its back more extended, and the whole back of the blade and the extended point thickly set with short spines, reminding one of the serrations on the antenne of many beetles like the Buprestids. In the car- penter-bees—X ylocopa—there is no variation from the type of the Bombus except the serrated margin of the blade is still more marked. In the female of the tailor-bees—Megachile—the ex- tended point and serrations are both absent, and we have again the form of this organ in the honey-bee. The number of the teeth in the cavity however, is less, there being from forty-five to fifty. In Osmia and Andrena (Fig. 3), the arrangement is much as in the Xylocopa; in Nomada the serrations are less spinous and more scattered, while in the beautiful species of Ango- chlora the cavity is quite shallow, the blade of the spur narrow, and the spines on the back and point of the blade slim and hair like. , Fio. 3. In the several families of wasps we find this pollen cleaner, well developed, and in some cases quite modified from the same in bees. In the paper-making wasps— Vespidee—it is much as in the lowest bees—N omada and Angochlora. The cavity is more shallow than in the honey-bee, the membranous portion of the blade is quite narrow, and the appendages on the point of the blade are hair-like, though those near the base remind one of saw teeth. In sand-wasps—Bembecidee—this organ is much as seen in bees and paper-making wasps; though the point of the blade is very long, and the back and point both thickly set with fine hairs. ioe In all species of mud wasps, belonging to se the family Sphegide (Fig 4) we find an in- teresting modification in the spur. Here the membranous portion of the blade is nearly Fra. 4, obsolete, while its inner margin is concave and fringed with a toothed brush much as seen in the cavity, though the teeth are shorter. The end of the blade is blunt, and ts from five to eight heavy appendages, which, when magni- fied, look like so many fingers. 196 Morphology of the Legs of Hymenopterous Insects. In the beautiful mud wasps of the family Pompilide, this appa- ratus is much as in the Sphegide, except that the cavity is more shallow. The fringe on the spur is peculiarly fine and beautiful. The spur is pointed, the point being flat and margined on both sides with spines. In the Mutillide this organ is specially well shown. The type is that of the bees and Vespide, as the blade is membranous and without the fringe. The back and both sides of the point, how- ever, are covered with a row of spinous hairs. In the ants—Formicide—(Fig 5) the cav- ity is shallow and the fringe well marked in the cavity and on the spur where it is double, and while this brush is beautiful, it is not widely different from the hairs on the point of the blade, and on the remaining Tii of the basal tarsus. In Ichneumonide (Fig. 6), and Braconide we find this antenna cleaner, less developed, though still present. The cavity is E hardly more than an in- bjao e clined plane, the rise at the distal end being very slight. The spur is marked by a distinct concavity, and the fringe is present in the cavity and on the spur, though the brush in case is made up of coarser hairs than are found in bees or wasps. In the species of Chrysidæ we find this apparatus more perfect than in the Ichneumonidæ. The cavity is deeper, the spur con- cave, and both show the comb or fringe well marked. The species of this family are unique in that the concave spur is fringed to the very point of the blade. In the minute Proctotrupidæ the antenna cleaner is even less de- veloped than in the Ichneumon flies. The cavity is almost wholly obsolete, the spur is only slightly concave, and the hairs forming the brush are hardly different from the other hairs of the leg. In the Chalcid flies—Chalcididee—the cavity is wholly absent, and the only suggestion of this apparatus is in the slightly curved spur. The brush is also obsolete. The same is hardly less true of thegall- Morphology of the Legs of Hymenopterous Insects. 197 flies—Cynipide. In the saw-flies—Tenthredinide—(Fig. 7), there is no hint of the cavity on the first tarsus; but a slight concavity of the spur, with the membrane just visible, still suggests the “ pollen cleaner.” In the horn-tails—Uroceridze—the only re- minder we have of the antenna cleaner is in the slightly curved spur. The membranous part of the blade is wholly wanting. In the study of this apparatus I have been very much interested to note how persistent is its type within each family. I have care- fully examined very numerous specimens, and I think we could, from the study of this organ alone, arrange the species of Hymen- optera, with very few exceptions, in their respective families. The same is also true in many cases of genera. We shall not wonder at this as we come to study the function of the organ and note its great importance. No one who has studied bees closely can doubt for a moment the functional importance of the antenne. As touch organs, they are most delicate and wonderful. The work of the hive bee is largely performed in total darkness. Yet very intricate operations are carried on with unerring exactness. This is only possible through the aid of those very sensitive tactile organs—the antenne. There is hardly less doubt that the antennz are the scent organs of insects. And with Hymenopterous insects, especially of the higher families, the sense of smell is of exceeding importance. It has been thought also that the antennæ serve as organsof hearing. This, however, is Probably not true. We see then that it is of the highest importance that these organs be kept free from all dust. But the very habits of most Hymenopterous insects, visiting, as they do, flowers laden with pollen, as do all except the lowest families, or digging in the mud and dust, as do many bees and Wasps, tend to soil the antenne. And it is no more necessary for the microscopist to brush the lenses of his objectives than for the bee or wasp to dust its antenne. That the function of the apparatus just described is to brush or free from dust the antenna is easily proved by experiment. We have only to imprison a bee or wasp on the window pane of our room, and quietly dust its antennæ with lime or flour, when we will See it pass an anterior leg forward, draw an antennæ through the Fig. 7. 198 Morphology of the Legs of Hymenopterous Insects. cleaner, after which the bee will pass the fore legs, now foul with dust, between the brushes formed by the soft hairy inner faces of the basal tarsi of the middle legs. This will be repeated several times, when upon examination the antenne will be found entirely freed from the troublesome dust. In case of the wasp, as Polistus annu- laris, the atitenne are cleaned the same as just described except that the leg or antenn cleaner is cleaned by passing it between the jaws instead of between the middle legs. As we are sure of the function of this beautiful apparatus we do not need to refer to the wonderful correspondence in size of the cavity in each separate case, with the antennæ of the same insect, which would be added proof if such were needed as to its function. I will also state that I believe L have found an antenne cleaner in some beetles, especially carabids. In these cases the cavity and lid are both on the tibia a little dis- tance towards the body from its farther end. 7 In the honey-bee on the outer end of the tibia, just opposite the antenne cleaner (Fig. 1), is a small brush. This has been regarded by some as a cleaner of the antenne cleaners; but we have seen that the latter organs are cleaned in another way. I have never seen these brushes used to clean the cavities, though I have observed closely. The fact that other bees, wasps, ants, etc., have no such, brush makes me doubt such function. The branching, fluffy hairs which cover the upper part of the fore leg (Fig. 1) of the worker honey-bee are like the same in other legs of the same insect, of use in gathering the pollen. From these hairs the pollen is combed off and transported to the pollen baskets. Opposite the side of the basal tarsus which contains the cavity of the antenne cleaner of the bee (Fig. 1), is a comb formed of quite stiff hairs. This is used to free the hairy compound eyes of the bees of dust, pollen, etc., and also to comb the pollen off the lighter hairs. The former function may be observed by closer observation, as the bee is seen to wipe its pollen-begrimmed eyes, much as the common house fly is observed to rub its eyes, face and antenne. The middle legs of bees are covered with the compound hairs to the end of the tibia where a s EAA prominent tibial spur (Fig. 8) \ — SS nS is seen, but no more prominent Tein in the honey-bee than in other bees and in wasps. Indeed it is even larger in drones than in the Morphology of the Legs of Hymenopterous Insects. 199 worker bees. It has been claimed that this is the lever with which the bee pries off the pollen mass into the cell ; but the fact that these are no more prominent than in other in- sects where there is no such function to be performed, and the fact that the stiff hairs which point outward at the ends of these and all the legs are better fitted for this work, gives reason to question the accu- racy of this view. On the inside of the first tarsal joint of the middle legs (Fig. 8) is a fine brush thickly set with hairs, _ x which, as we have already seen, is used to clean the antennæ cleaner, and, as I often noticed large masses of pollen adher- ing to this brush, I am led to the conclu- sion that these are hands or claspers that aid to bear the pollen to the baskets on the posterior legs. The lower or outer, hairs of this brush are spine-like and doubtless aid as already suggested in push- Ing the loads of pollen from the legs into the cells of the comb. Upon the first three joints of the pos- terior legs, the coxa, trochanter and femur (F 1g. 10) the soft, compound, polen gather- ing hairs are well shown. In the honey bee the tibia and first tarsus ars wonder- fully developed. On the outside (Fig. 9) are cavities for holding the pollen. These shallow cavities, one in each of the joints, are bordered with course hairs, which serve as so many stakes to aid in holding the large pollen masses which the - bee is Often seen carrying to the hive. Opposite the concavity of the tarsal joint Fra. 9. (Fig. 10) on the inside are to be seen nine or ten rows of beautiful 4 ellow hairs, which form as many combs or brushes, which serve © collect and transport the pollen from different parts of the bee to the pollen baskets, If a bee is captured while collecting pollen, 200 Morphology of the Legs of Hymenopterous Insects. these beautiful brushes will always be found with more or less pol- Jen adhering to them. Of course the combs of one leg are used to fill the pollen basket of the opposite legs. As before stated, this work is in part performed by a similar but less perfect arrangement on the corresponding portion of the middle legs. AY, Between the i tibia and first tarsus of the posterior legs of the honey- bee (Figs. 9 and 10) is a very curious joint, remind- ing one of a steel trap or the jaws of an animal, the tibial or inner jaw of which is well cover- ed with quite pronounced teeth. This is used to grasp the delicate wax scales from the pockets ` where they are secreted beneath the abdo- men, and transfer them to the mouth where they are kneaded into material suit- able for comb. The claws and pulvilli, which terminate the feet of all Hymenopterous insects (Fig: 8), are specially well developed in bees, The former have a strong tooth and are useful not only in walking on wood and other similar surfaces, but also in holding ‘ the bees the one to another in case of clus- FIG. 10. tering.

They are large and glandular, and by secreting a viscid adhesive material enable a bee to walk up a smooth surface like that of glass. We thus under- stand why a bee fails in its attempt to walk up a moistened or powdered glass surface. When a bee walks on wood the pulvilli are turned back, when on glass the claws are similarly made to change their position. DIRECTIVE COLORATION IN ANIMALS. BY J. E. TODD. UCH has been written by Wallace, Darwin and others concern- ing the protective effects of coloration in animals, and this adaptation perhaps accounts for most of the chromatic characteristics of animals. Darwin has also shown how many may be accounted for by sexual selection, and Wallace has referred many of those, still remaining unexplained, to the play of color-producing forces uncontrolled by natural selection. So far as the author is aware, however, there has been no distinct enunciation of the principle sketched in the following pages. The nearest approach to it is a remark of Darwin in regard to the rab- bit’s white tail—that it might serve as guide to the young in follow- ing the old ones to the burrow; and another—that the stripes of the zebra may be of use to stragglers in recognizing their fellows at a distance, (Vide Am. Nar., 1877.) Wallace approves the suggestion, and, from some notes of his recent Baltimore lectures, it may be inferred that he has carried the Principle further. But in their published writings both these emi- nent naturalists refer several distinct cases to other sources, which in the following pages will be claimed as examples of what, for want of a better name, we have styled directive coloration. And whether the views hereinafter to be advanced prove to be entirely novel Or not, they have, so far as here expressed, sprung entirely from the author’s own observation and study. He regrets that both have necessarily been so limited that he cannot multiply examples as freely as nature has supplied them. What is here offered is only a sketch of what might be wrought out by any one having time to carry out the work in its details. 202 Directive Coloration in Animals. The first observations which eventually proved the germ of this paper were made on the plains of Dakota. During the long, mon- otonous rides over that region, one pleasant circumstance was the sudden rise of various birds from the nearly naked ground and their as sudden disappearance on lighting. Ere long it was noticed that in the process of lighting there was, very commonly, a conspicuous flashing-out of white on wings or tail, or on both. This was noticed in several of the sparrows, the meadow-lark, the lark-bunting, the Carolina dove, and less prominently in the prairie-hen or grouse. i facts were noted also of the jack-rabbit and antelope. The question then arose, very naturally, Why is this prevalent char- acter? Of what advantage is it? For the smaller birds, the answer came readily. The plains are constantly scoured by hovering hawks —therefore, protective coloration is of prime importance. If, how- ever, they should become of a uniform gray color all over, they would be as completely and constantly hidden from their friends as from their foes. That would be quite disastrous, especially where the former are fewer than the latter. To prevent such a result, there is the following arrangement. When at rest, or about the ordinary occupation of feeding, the gray surface only is exposed ; the same is true also in some cases during flight; but in checking its velocity for lighting the tail is fully spread, exhibiting the con- spicuous colors fully, and marks the location of the leader, that the rest may govern themselves accordingly. To escape the hawk, should he happen to note the location, the sparrow resorts to doub- ling on its course and skulking. When the danger has passed, the flock, if they have followed the leader, are likely to be within call of one another, and if they have become too much scattered, this same automatic telegraphy must assist much in enabling the strag- glers to find their fellows. Some species, as the meadow-lark, have a habit of spreading the tail at almost every chirp. This would seem to work as rationally as the rallying-call of the bugle and the waving of a flag to call a troop together. Yet after all, in the bird it is doubtless mainly automatic, the effort of the ery producing the twitch of the tail, as truly as in the prairie-dog. But this conspicuous flash tells more than the place of alight- ing. It reveals the species at hand. These white patches form @ kind of natural heraldry among the denizens of the plains, by which each kind is recognized by friend and foe. Its vivid white secures Directive Coloration in Animals. 203 its utmost efficiency. It is, no doubt, often useful also at night, whenever there is any disturbance by storm or prowling enemy. Thus far, we have had in mind only the ordinary gray birds and animals of the plains, upon which the directive coloration is almost invariably white. But the principle extends farther. When the general coloration is white or light, the directive color is black or dark, as in the pelican, white crane, weasel, etc. In some which may be gray in summer and white in winter, both white and black may be found in close juxtaposition. Ina very few, black seems to serve the purpose, even with gray plumage, as in the horned lark and some sparrows (?). The principle may include also cases where more brilliant tints than those of the white-black series are employed. Soon after our interest had been awakened in the cases already mentioned it was our privilege to examine a large collection of skunks which some fortunate trappers had captured. The striking white lines on the black ground and their fantastic and very variable forms raised again the question, Why? Our idea of directive coloration found a new direction for its application, and it readily suggested satisfactory answers to the query. Here were animals living con- stantly in dusk and darkness. The conspicuous tail, as Belt re- marked long ago, may be classed as a warning signal, and therefore protective; but why the elaborate white lines and spots? These are only useful at shorter distances, and, therefore, presumably to fellow-individuals of the same species. We can readily understand how they may clearly reveal not only the general position of the body, but also its attitude ; and by the individual variations in the breadth and continuity of the lines, individuals may recognize one another at night, or in their burrows. In short, these directive mark- ings are in this case what signal-lights or flags are to vessels and cars, Similar reasoning accounts for the markings prevalent in the raccoon. badger, chip-munk, and other burrowing animals. So, too, it ac- Counts for some of the markings about the heads of the sparrows, larks, ducks, and numerous other birds ; also, about the muzzle, ears and throat of antelope, deer, hares and other mammals, whether protectively colored or not. These markings are more distinct and more frequent about the head, because of its greater expressiveness and importance. Of course, in this general outlining of our idea we need not attempt to classify rigidly particular markings, for some 204 : Directive Coloration in Animals. may be useful in more than one way. For example, the ears of the jack-rabbit may serve to notify his fellow of his presence at a dis- tance, and when close at hand they, doubtless, are very expressive of the bodily position and mental condition of their owner. Looking now over the whole animal kingdom, so far as the more comprehensive works on natural history and more careful descrip- tions of our local faunas will allow us, we find a vast number of spots and lines about the head, shoulders, flanks and tails of animals belonging to all the so-called sub-kingdoms; and we find in our theory a plausible explanation, in harmony with the workings of natural selection. We find some, however, which, while properly associated with the cases already described, do not come under either of them exactly. Hitherto we have considered where only a few individuals were con- cerned and only in the casual relations of ordinary life. There are cases where large numbers herd together, oftentimes moving rapidly in crowded phalanx or disorderly mass, where each must closely regulate his movements according to the action of his immediate companions if he would avoid collision and injury. Not only is this important in diurnal travels, but in the nocturnal bivouac, and especially in a stampede at night. In this way we may explain the stripes of the zebra, koodo, etc., and the numerous bright and ex- tended markings on the various African antelopes. It would seem that the greater and more ferocious carnivores of the tropics might have an influence to intensify these features. The bright markings of hyenas and the hunting-dogs are other conspicuous examples, traceable to quite a different combination of circumstances. striking marks, which we have noted under another head, may be also helpful in the way just described. For instance, the markings about the head and tail of wild geese and ducks and the black tips of the wings of pelicans may assist them much in keeping their regular order of flight ; so, also, the markings upon sparrows, which are helpful in the ways already indicated, during their summer-life may also be of service during their griion by helping them to harmonize their movements. ; It will be seen by a moment’s thought that most of the markings helping to show the position of the body may be of pre-eminent value during courtship, especially during thesupreme moments of col- tion. Is would not be strange if this advantage might havea tendency Directive Coloration in Animals. 205 to intensify certain lateral and caudal markings, or even to produce in them sexual differences. We should naturally expect this to be as manifest in nocturnal animals as anywhere. To this cause we are disposed to refer the different colors of the wing-spots of night- hawks and other Caprimulgide: In the males they are white, while in the females they are rufous. Possibly, some of the cases which Darwin considers the results of sexual selection transferred from the male to the female may be referred to this influence. Another relation may, presumably, modify ‘directive coloration to a considerable degree, especially in animals which, though roving the fields themselves, secrete their young. Deer, swine, lions, ete., may be taken as examples of this. The vivid markings upon the young may’assist much in the care which the mother gives in the dim light of the hiding-place and at night. This explanation does not necessarily conflict with the more commonly received opinion —that they are the effect of heredity, revealing the coloration of Some remote ancestor. It suggests, rather, the further inference that that ancestor was either gregarious and living on open plains, or else was more solitary and prowling, skulking in dim lights. Our theory would offer a rational explanation for its persistence in the earlier stages of living species. It will be noticed that we have drawn our illustrations entirély from the mammals and birds. We would not imply that our theory is limited to these. Insects, fishes and reptiles may afford equally good examples, We would remark, in concl usion, that this sketch does not attempt to give details more than may be necessary to present our view in- telligibly. Of course, we recognize the validity of the theory of typical coloration consisting of those primal tints and patterns which have been ascribed to the combined action of chemical, physical and vital forces only ; also the theories of protective and ornamental colorations, which have been evolved from the typical by the action of natural and sexual selection. We do not profess to be able to refer every tint and pattern of coloration to its predetermining con- dition or advantage. That would be well-nigh impossible. But if enough has been given and with sufficient discrimination to satisfy _ Most minds, that adaptation for directive purpose is a real advan which has been decidedly effective in determining the coloration of mals we are content. ? 206 Directive Coloration in Animals.

ACCORDIN G to the new scheme for the classification of massive ` rocks, proposed by Professor H. Rosenbusch of Heidelberg in the. second edition of his “ Mikroskopische Physiographie der Massigen Gesteine,” these are divided into three great groups, (I) intrusive rocks, (II) vein rocks, and (III) effusive rocks. The fundamental notion underlying this classification is briefly as fol- lows: the structure possessed by rock masses as we find them in the earth is dependent upon two circumstances—(1) the chemical composition of their original liquid magmas, and (2) the conditions under which these magmas cooled. The effect of chemical compo- sition upon the structure assumed by a rock magma in its passage to a solid state has not been definitely ascertained. Results recently obtained by Lagorio, however, indicate that the composition of — the unsolidified portions of rock masses, exerts much more influence upon the final structure of the rock than has hitherto been supposed. The rapidity with which a rock cooled, as well as the conditions under which this took place, have long been known to be quite influential in determining its structure. Those rocks which cooled 208 Classification of Massive Rocks. slowly under great pressure and at great depths, where crystalliza- tion was gradual and undisturbed, assumed a granular aspect. — Those which cooled quickly under low pressure became glassy. Those which began to crystallize in the depths of the earth, and continued their crystallization after the transference of their entire mass to other places, took on a porphyritic habit. Since, then, the structure of a rock indicates with some degree of certainty the prevailing conditions under which it was formed, it affords a conve- nient basis for the foundation of rock classification. And further, since the conditions under which a reck is formed are directly connected with its geological relations to surrounding rocks, the most logical classification is that which takes primarily into consid- eration these relations as the causes which produce the effects noted as structure. Rosenbusch begins, then, by separating all massive rocks into the three great groups mentioned above. The intrusive or plutonic rocks are those which formed at great depths (Tiefen-gesteine); the effusive or voleanic rocks are those which flowed out upon a land surface and there solidified (Erguss-gesteine), and finally the second group, the vein rocks, are those which have been found only in veins or dykes in other rocks, and which may or may not be con- nected with the effusives. Before discussing the classification in detail it will be necessary to define a few terms introduced by Rosenbusch to facilitate the description of the more prominent structures characterizing rocks, as we find them to-day. A rock composed akon. of i minerals is said to be holocrystalline. When it consists entirely of an unindividualized, structureless mass, it is known as amorphous. When it is partly amorphous and partly crystalline, ¿.e., contains crystals in a hyaline ground-mass, the structure is described as hypoerystalline. An idiomorphic mineral is one whose form is determined by the crystallizing forces acting within itself. An idiomorphic mineral is bounded by crystal planes. An allotriomorphic mineral is one which possesses a form due to the action of external forces, and not to the action of intramolecular forces. An allotriomorphic mineral is not bounded by its own crystal planes. Of two contiguous minerals in a rock, one idiomorphically developed, and the other allotriomorphically developed, the former is the older, compelling Classificution of Massive Rocks. 209 the latter to assume a form which it would not do were it free to obey the forces at work within itself, tending to bound it with certain definite crystal planes. A mineral is described as occurring in but one generation in a rock when all of its individual members have separated out con- tinuously in the same interval of the rock’s formation. When a portion of the individuals have separated out during one interval, and then, after other minerals have crystallized, another portion has separated, the mineral is said to occur in two generations. When the constituents of a rock occur in but one generation, the rock is granular in structure. When but a small portion of these are idiomorphically developed, the rock is Aypidiomorphically granular. When a relatively large portion or all of the constitu- ents are idiomorphically developed, the rock is panidiomorphic, When none of the constituents are so developed the structure is allotriomorphically granular. A porphyritic rock is one which contains one or more minerals. in more than one generation. I. Inrrustve Rocks. The intrusive or plutonic rocks are those which were formed at great depths. They were intruded between other rocks which existed before them, either as bosses or sheets, which never reached the surface, or they are the deep-seated portions of large masses. which may have flowed out upon the surface of the earth. They may have been formed at any geological age, but are only found in the oldest portions of the globe, because only in these portions has sufficient time elapsed to allow of their exposure by erosion. They are characterized by the possession of a hypidiomorphie granular structure, although in certain cases, where these rocks were intruded as flows between others, they sometimes tend to the Panidiomorphic development. They are divided, according to their chemical and mineralogical Compositions, into eight families. A. THE GRANITES. The granites are composed essentially of quartz and an alkaline feldspar, and one or more of the minerals of the mica, amphibole or PyToxene groups, sometimes tourmaline, and almost universally certain apatite, zircon and iron oxides. 210 Classification of Massive Rocks. They are divided into three divisions, as follows :— 1. TRUE GRANITES, containing both light- (muscovite) and dark- colored micas (biotite, etc.), including (A) lithionite granite, in which the dark ingredient is a lithium mica. (B) luxullianite, in which tourmaline replaces the lithio- nite. 2. GRANITITES, containing a biotite as its only micaceous constit- uent, including (A) lithionite granitite, with a lithium mica as the promi- nent micaceous constituent. (B) amphibole granitite, containing an amphibole in addi- tion to biotite. (c) augite granitite, in which an augitic mineral is present. 3. AMPHIBOLE GRANITES, containing amphibole in place of the biotite of the granitites. | B. THE SYENITES. Syenite differs from granite in the entire or almost entire absence of quartz as an essential constituent. The syenites besides contain no primary muscovite, but do contain a greater or less amount of plagioclase. The alkaline feldspars embrace, in addition to ortho- clase, both albite and anorthoclase to a subordinate degree. They are divided into :— 1. TRUE SYENITEs, or hornblende syenites, composed of orthoclase, hornblende, and usually a little biotite. 2. Mica SYENITES, which often contain albite in addition to ortho- clase and biotite. 3. AUGITE SYENITES, in which a monoclinic augite and orthoclase constitute the essential components. C. THE ELÆOLITE SYENITES. The elæolite syenites are quartz-free combinations of orthoclase and elæolite with one or more of the iron-bearing minerals of the pyroxene, amphibole or mica groups. With these is almost always associated some plagioclase and a greater or less amount of sodalite. Their structure, though usually granular, sometimes becomes porphyritic through the occurrence of feldspar, elæolite and soda- lite in two generations. It is probable that this structure is con- Classification of Massive Rocks. 211 fined to the outer edges of large masses and dyke forms of the kroc. The various occurrences of elæolite syenite are not well enough characterized to admit of a further classification. D. THE DIORITES. The diorites may be defined as rocks composed of plagioclase and biotite or hornblende, with or without quartz. Orthoclase and microcline sometimes accompany the plagioclase, and in certain cases augite partly replaces the biotite or hornblende. The struc- ture of the diorites departs somewhat from the typical structure of the intrusive rocks in that the plagioclase and the biotite, amphi- bole and augite are sometimes idiomorphically developed. The diorites are divided into :— 1. Mica Drortres, in which biotite predominates over hornblende, including (A) mica diorite, which is quartz-free. (B) quartz, mica diorite, which is quartz-bearing. 2. DIORITES, in which hornblende is the most prominent colored constituent, including (A) diorite, and (B) quartz diorite. 3. AuerrEe DIoRITES, containing a large amount of augite, including (A) augite diorite, and (B) quartz-augite diorite. E. THE GABBROS. The gabbros are combinations of plagioclase and a monoclinic or an orthorhombic pyroxene, with or without olivine. Their structure varies slightly from the typical granular struc- ture, in that the plagioclase occurs in broad lath-shaped crystals. They are divided, according to the nature of their pyroxenic constituents into :— ABBROS, which contain, as their pyroxenic constituent, dial- lage, or a monoclinic augite with a composition approaching that of diallage. The gabbros include (A) gabbro proper, which is olivine: including two varieties : 212 Classificution of Massive Rocks. (a 1) hornblende gabbro, in which diallage is partly replaced by hornblende, and (a 2) hyperite, containing a little olivine and some orthorhombic pyroxene. (B) Olivine gabbro, olivine-bearing. 2. Norires, which contain an orthorhombic augite as the principal pyroxenic component. The norites are divided, according as to whether they contain olivine or not, into (A) norite, and (B) olivine norite. F. THE DIABASES. The diabases are composed essentially of plagioclase and augite, with or without olivine and quartz. They form a well-marked class among the intrusive rocks, which differs in many respects from the other intrusives, and approaches very near in characteristics to some of the effusives, This is due principally to the fact that the diabases occur as dykes and intruded layers between sedimentary beds, and thus tend to assume in some degree the structure possessed by sheets which have cooled on the surface under atmospheric pressure alone. They are frequently accompanied by tufas, and they often possess amygdaloidal upper surfaces. Since, however, the pressure under which they were formed was much greater than that under which the volcanic rocks were produced, and, as we may suppose, their cooling much more — gradual, the diabases are holocrystalline and hypidiomorphic- granular, as distinguished from the hypocrystalline and porphyritie structures of the members of the effusive class. Nevertheless, the tendency of the plagioclase to assume idiomorphic forms is so strong that an approach to the porphyritic structure is noticeable in many diabases, As among the gabbros, the first differentiation of the diabases is dependent upon the presence or absence of olivine as an essential constituent. 1. Drapases are olivine-free combinations of plagioclase and augite, usually with a little hornblende and mica. (A) diabase proper contains no quartz. (B) quartz diabase contains quartz as a primary compo- ‘nent, including Classification of Massive. Rocks. 213 (b 1) sahlite diabase, which contains an, idiomorphic colorless monoclinic pyroxene (sahlite), and (6 2) enstatite diabase, containing an orthorhombic augite. (C) teschenite is analcite-bearing. 2. OLIVINE D1aBasEs contain olivine as an essential constituent in addition to plagioclase and augite. G. THE THERALITES. The theralites, formerly called teschenites, are intended to embrace rocks composed of. plagioclase and nepheline, together with the accessories angite, biotite and olivine. Rocks of this composition are not known to exist among the intrusives, unless certain basic rocks from Montana, lately described by Mr. Wolff, belong here. Corresponding members of the effusive class are, however, quite well known, and it is therefore expected that true theralites will be found at some time in the future, even if the Montana rocks should turn out not to belong in this family. H. THE PERIDOTITES. The peridotites are the most basic of the intrusive rocks. They contain no plagioclase, but usually do contain a large amount of olivine and a mineral of the amphibole or pyroxene families. Their bisilicate constituent is made use of for purposes of sub-classifi- cation. 1. Prcrrre is composed of olivine and augite. 2. ÅMPHIBOLE Prcrrre contains olivine and hornblende. 3. WEHRLITE consists of olivine and diallage. 4. HARZBURGITE is a combination of olivine and a rhombic pyroxene. : 5. LHERZOLITE contains olivine, diallage and a rhombic pyroxene. 6. Dursrre consists of olivine and chromite. II. Vern Rocks. The class of vein rocks includes those which exist as independent geological bodies only in the form of veins or dykes, although many similar rocks occur also as facies of certain intrusive and effusive rocks. This class is not as well defined as either the intrusive or the effusive class, Rosenbusch personally is inclined to place them 214 Classification of Massive Rocks. with the intrusives, but since no direct connection has been traced between them and deeply buried rock masses, of which they may be regarded as a part, he decides to place them in a separate group until more knowledge of their relations has been obtained. The structure of the vein rocks resembles in some respects that of the intrusive rocks, and in others that of the effusives. Three well-marked types are recognizable: the granitic, the granite- porphyry, and the lamprophyre. Since these three types can be ` distinguished macroscopically, and are very characteristic, they are made use of to separate the vein rocks into three groups, which are in turn subdivided into families, according to mineralogical consti- tution, as in the class of intrusive rocks, II. A. THe Granitic Vern Rocks. The structure of the granitic vein rocks differs from that of the intrusive rocks, in that their individual constituents tend to become idiomorphic. In most cases this tendency has gone so far as to produce a rock, all of whose components are bounded by their own crystal outlines. They are then panidiomorphic-granular. An approach to the porphyritic development is sometimes the result of a repetition of conditions which allows of the separation of some of the constituents in two generations. The granitic vein rocks include :— 1. APLITE, or muscovite granite, consisting of orthoclase, quartz and muscovite. (A) pegmatite is a coarse-grained aplite. (B) beresite is orthoclase-poor aplite. : II. B. THE GRANITE PORPHYRY GROUP. The structure characteristic of this group of rocks is the holo- crystalline-porphyritic. Their ground mass is a granular aggregate of crystalline minerals. The predominant porphyritic crystals are light in color, i.e., they are neither iron nor magnesia bearing. The occurrence of iron and magnesia-bearing minerals as porphyritic constituents is exceptional, The group is divided into ;— A. THE GRANITE PORPHYRIES. . The mineralogical composition of this family is the same as that Classification of Massive Rocks. 215 of the granites. The porphyrytic constituents are quartz, ortho- clase, and usually one or more of the granitic minerals, biotite, hornblende, augite or muscovite. The same minerals occur also in the ground mass. No attempt is made to divide the granite porphyries, although it may be convenient to separate them into :— 1, GRANITE PORPHYRY proper, containing no muscovite, and 2, ELVAN muscovite—rich varieties. B. THE SYENITE PORPHYRIES. The syenite porphyries differ from the granite porphyries in the absence of quartz from among the porphyritic crystals, In all other respects they are similar to them. Quartz occurs in the groundmass, and plagioclase is more common than in the granite porphyries. They are divided, according to their principal iron-bearing constituent, into :— : 1. HORNBLENDE SYENITE PORPHYRY, which contains orthoclase and hornblende as the most prominent porphyritic constituents, 2. MICA sYENITE PORPHYRY, in which orthoclase and biotite occur in porphyritic crystals. 3. AUGITE SYENITE PORPHYRY, in which augite is the most important non-feldspathic porphyritically developed component. C. THE ELEOLITE SYENITE PORPHYRIES. The elæolite syenite porphyries usually contain eleolite as the Most important porphyritic constituent after orthoclase. In one or two cases the elæolite is found only in the groundmass. Rocks belonging to this family have not been sufficiently studied to admit of further classification. D. THE DIORITE PORPHYRITES. The diorite porphyrites are not very widespread. They consist of plagioclase, hornblende, and sometimes quartz and biotite as Porphyritic crystals in a groundmass composed principally of Plagioclase and quartz. They are divided into families, in accordance with the exist- ence or non-existence of quartz among the porphyritic crystals, 216 Classification of Massive Rocks. D. &@ DIORITE PORPHYRITES. 1, DIORITE PORPHYRITE contains plagioclase and hornblende as rphyritic constituents. 2. MICA DIORITE PORPHYRITE contains plagioclase and biotite in porphyritic crystals. D. b QUARTZ DIORITE PORPHYRITES, 1. QUARTZ DIORITE PORPHYRITE contains plagioclase, quartz and hornblende as the porphyritic ingredients. 2. QUARTZ MICA DIORITE PORPHYRITE. In the rocks of this class biotite takes the place of the hornblende in the quartz diorite porphyrites. II. E. THE LAMPROPHYRE GROUP. The lamprophyre group differs from the granite porphyry group of vein rocks in that the iron and magnesium-bearing silicates, hornblende, pyroxene and biotite are the most important constituents occurring in two generations. Their feldspar, which may be either orthoclase or plagioclase, occurs in but one gener- ation. In composition they resemble the syenites and diorites of the intrusive rocks, and are therefore divided in accordance with this resemblance, A. SYENITIC LAMPROPHYRES, The syenitic lamprophyres consist of an alkaline feldspar, biotite, hornblende and pyroxene as essential constituents. They possess both the panidiomorphic-granular and the holo- crystalline-porphyritic structure. The former sometimes passes over into the hypidiomorphie-granular. | They are subdivided according to the presence or absence of biotite as a prominent constituent. 1. MINETTEs contain biotite as the principal iron-bearing con- stituent, both in the granular and the porphyritie forms. (a) hornblende minettes contain hornblende in addition to i iotite. (B) augite minettes have augite besides biotite as a promi- nent constituent, Classification of Massive. Rocks. 217 (b 1) olivine minette is an augite minette containing olivine. 2. VOGESITES contain hornblende or augite as the most important colored constituent. (A) hornblende vogesite. In this, hornblende predominates over augite, (B) augite vogesite possesses augite in larger quantity. B. DIORITIC LAMPROPHYRES. The dioritic lamprophyres differ from the syenitic lamprophyres in containing plagioclase instead of an alkaline feldspar in addition to biotite, amphibole and augite. Like the syenitic varieties, these rocks are also developed with the panidiomorphie granular and the holocrystalline porphyritic structures, : Their separation into two classes also depends upon the greater or less amount of biotite in their composition. 1. Kersantitr. This rock is characterized by the possession of large amounts of biotite. (A) Aschaffite contains quartz and feldspar in addition to the iron-bearing minerals in porphyritic devel- opment. (B) Olivine kersantite contains olivine in addition to the essential constituents of the kersantite. (b 1) pilite kersantite, in which the olivine’ has been altered to pilite. 2. CAMPTONTTE contains hornblende in place of the biotite of the ‘kersantites. (TO BE CONCLUDED.) 218 Glacial Erosion in Norway. X.—GLACIAL EROSION IN NORWAY AND IN HIGH LATITUDES: BY PROFESSOR J. W. SPENCER, B.A.SC., PH.D., F.G.S. E URING the summer of 1886, it was my good fortune to visit the three largest snowfields in Norway, namely, the Folge- fond, at the head of Hardangerfjord in southern Norway, whose area is 108 square miles; the Jostedalsfond, two degrees to the north, beyond Sognefjord, whose area is 580 square miles, and the largest snowfield in Europe; and the Svartisen, extending from just inside the arctic cirele for forty-four miles northward. All of these snowfields send down glaciers to within from 50 to 1,200 feet of the sea. These snowfields are not basins like those in the Alps, but are mantles covering the tops of plateaus from 3,000 to 5,000 feet or more above the tide, from which great cañons suddenly descend to the sea, and extend themselves as fjords, from 1,000 to 4,000 feet in depth. - Many of the Norwegian glaciers are rapidly advancing. In their progress they do not conform to the surfaces over which they pass, but are apt to arch over from rock to rock and point to point, especially as they are descending the ice-falls. Thus are produced great caverns into which the explorer can often wind his way for long distances. Beneath the glaciers of Fondal, Tunsbergdal, and Buardal, in the northern, north-central, and south-central snowfields of Nor- way, as well as under other glaciers, I observed many stones enclosed in ice, resting upon the rocks, to whose surfaces—sometimes 1 Read before the Royal Society of Canada, May 25, 1887, and the American Association for the Advancement of Science, New York, Aug- 1887.

Although held in the ive on four sides, with a force pushing. downward, the viscosity of TAF W HA | i a .—Section of Fondalsbreeen, a, bed rock; c, cavern under glacier 5; d,loose ne; f, groove under the ice. the ice, or the resistance of its molecules in disengaging themselves from each other in order to flow, was less than that of the friction between the loose stones and the rock ; consequently the ice flowed around and over the stones, leaving long grooves upon the under- surfaces of the glacier. The first observation made was at Fondals- breen (Fig. 1), where an angular stone (Fig. 1 d) whose section was ten by eighteen inches, rested upon the sloping face of smooth rock (a). For twenty feet below the stone, the under-surface of the glacier was grooved (f) by the moulding of the ice about the obstacle. This distance showed the advance of the glacier after the stone had come in contact with the rock, for it had evidently been Completely buried at the lower end of the groove, before the ice had begun to flow about it. As the ice between the stone and the tock gradually disappears, the embedded stone does not suddenly cease to move, but drags, until enough of the surface rests upon the rock to allow of friction between the two granitoid surfaces to Overcome the viscosity of the ice, when the latter flows around the obstacle. Elsewhere, an example was seen of this action, The knife edge of a wedge-shaped piece of gneiss was pr i beneath the ice and resting upon the rock. The front end of this stone had moved beyond the subjacent surface, while the posterior 220 Glacial Erosion in Norway. end was still upon it. Yet the sharpness of the edge had scarcely been blunted. Abundant examples were found to show that the flowing of the ice about loose obstacles was quite the rule. Both large and small (even an inch in length), angular and rounded masses, lying either upon the rock, or upon morainic matter, were sufficient to channel the bottom of an advancing glacier. No blocks of rock were seen in the act of being turn loose from the floor or sides of the valley, and certainly there were no loose or solid masses being picked up by the advancing glacier. Fie. 2.—Section of Tunsbergdalsbreen, a, bed rock; ¢, cavern under ice b, å boulder; ee, moulding in ice of the form of d. At Tunsbergdalsbreeen (Fig. 2), whose lower end is 1,600 feet above the sea, a modification of the above described phenomena was seen. A roughly rounded boulder (Fig. 2 d) of thirty inches diameter was enclosed in the convex side of the glacier, which rose above it from thirty to forty feet in height. It was resting upon a surface, sloping at a high angle, and was held in place by the ice itself. As the surface of the stone, bearing upon the rock, was small compared with that held in the ice, it should have been dragged along. But it was being rolled, as shown by the mould- ing (e e) of its form in the glacier which was advancing faster than the stone was rolling down the steep slope. The pressure upon this stone could not have been merely that of the superincumbent ice, & few feet thick, but also that of a powerful component of the weight of a glacier from 1,500 to 2,000 feet high descending more or less Glacial Erosion in Norway. 221 like a fluid. The energy upon the boulder was sufficient to crush it into one large and two smaller masses, together with stone dust. When seen, the three fragments had hardly begun to part company. The abrasion of the solid rock by the fall of stones, and detached masses of ice and stones, was illustrated at the locality just named. The two guides and myself succeeded in detaching a large boulder of about five tons weight, adjacent to the edge of the glacier. It went rolling and sliding down a hundred feet or more, tearing away great blocks of ice which held a considerable amount of debris, and in its wake, the rock was more or less crushed or scratched.

According to the experiments of “Herr Pfaff,’ the temperature of 1 Nature, Aug. 19, 1875. 222 ` Glacial Erosion in Norway. ice has a great deal to do with its flow about obstacles. Below freezing-point, the movement is scarcely more than appreciable, while above that point, but not below, it may reach twenty-eight inches a day, or more. The conditions arising from the tempera- ture beneath the glaciers are more or less favorable for the move- ment of the ice, as the lower surfaces are never entirely below freezing-point, even in winter. Professor S. A. Sexe! found that the water flowing from a Folgefond glacier, in February, 1861, had a temperature of 1°R., whilst that of the air was 7°R. below freezing-point. The movement or flow of the ice about detached stones, rest- ing upon rocks, has been observed by Professor Sexe beneath the - Buarbre, and by Professor J. W. Niles beneath the Aletsch gla- cier.? Professor Sexe illustrates the moulding of the ice about a loose stone, which was held beneath the glacier by a projection of the rock. My observations were upon stones, not held up by rocky projections, but upon surfaces often sloping downward. Although Professor Niles did not record observations showing that there was definite movement of the stone, yet he concluded that there was a differential movement of the ice and the block. Whatever differential movement there is, it must be very incon- siderable, not only upon horizontal plains, but upon inclined sur- faces. In the former case the movement of the ice is reduced almost to zero, as shown by the measurements of Professor Tyndall upon the Morteracht, where the velocity of the surface, some dis- tance from its end, was fourteen inches, whilst that of the tongue of the glacier, as it reached the plain, was only two inches a day.” The most important condition favorable for holding stones in ice as graving tools is low temperature, which impedes its progress; but this condition beneath glaciers does not generally exist. At higher temperatures, the velocity of the glacier is not great enough to overcome its plastic movement and to drag along detached blocks. However, when the whole mass of ice is charged with sand and stones, there is no doubt that polishing and scratching are effected ; but when there are only occasional fragments in the bottom of the ice, as is commonly the case, the erosion from the sliding ceases as 1 Om Sneebreen Folgefon, af $.

Glacial Erosion in Norway. 223 soon as the resistance due to friction between the stones and the rock equals that due to viscosity, which, as observations show, is soon reached. Consequently, we should not expect to find great troughs or grooves scooped out of solid rock by the actual glacier. These I have not seen about the existing glaciers of Norway, which are not dependent upon atmospheric and aqueous erosion and the texture of the rock, although their surfaces may have been subse- quently polished. Generally speaking—as seen in the valley behind Fondalen Gaard, where the glacier is nearly free from sand, and contains comparatively few stones, as well as at many other places—the surfaces of the subjacent crystalline rocks, although of the form of roches moutonnées, with angles mostly removed, are not CaP Uti Leathe. a, ba >” ¥ 3 T 5 EP p $ CE aa E E a E T A A g l ower ey oction at Fondalsbreen, hh, zone along which ice (b) is flowing upon its , Smooth, but are as rough and as much weather-worn as similar rocks in warmer countries where no glaciers have been. U these surfaces, it is often difficult to discover scratches—even when Present—for they are often so faint as to be only rendered apparent by moistening the rock. Even the face of the hummocks are com- monly imperfectly polished. In other places, particularly at Tuns- bergdalbreen which contains much sand along the margin, the rocks are highly polished, and but little scratched. One is every- where surprised to find beneath the glaciers the great paucity of glaciated stones, and in many terminal moraines they are scarcely, if at all, to be found. * : The insufficiency of glaciers to act as great erosive agents is 224 Glacial Erosion in Norway. farther shown at Fondalen (Fig. 4), where a mass of ice thirty or forty feet thick abuts against a somewhat steep ridge of a rock, ten feet or less in height. In place of a stone-shod glacier sliding up and over the barrier, the lower part of the ice appears station- ary, or else is moving around the barrier, while the upper strata bends ‘and flows over the lower layers of ice (along the line Ah, Fig. 4). When the barrier to the advance of a glacier is met with, whether composed of hard rock, or of morainic matter, the ice, provided it be sufficiently high, flows over upon itself, yet when the sheet is no higher than the barrier, the lateral thrust may push it up some- what. The best example of the consequences of such a condition is X NV s if Uy AHA Fre. 5.—End of pty lege glacier at head of Holandsfjord, moving through a lake Mekat morainic barrier to be seen at Svartisen glacier (Fig. 5), at the head of Holandsfjord, which descends to within sixty feet of the sea, where it ends in a morainic lake of considerable size, the northern side of which is filled with the glacier. The water of the lake rises, in part, to the level of the ice, or over it, where the waves of the lake are depos- iting sand upon its surface. Part of the ice is not less than twenty- five feet thick, and most of it is probably double that thickness. Some of the strata of ice are pushed up and rest at 5° from the horizontal. But the interesting points are at the end of the glacier, where it impinges against the morainic barrier. Being unable to advance, the lateral pressure has forced up an anticlinal ridge or rather dome in the ice, to a height of fifteen feet, along whose axis there has been a fracture and fault. Upon this uplifted dome rests the undisturbed sand stratified in perfect conformity to the surface, which was formerly just below the level of the lake, As the ice about the line of fracture melts, the sand falls over and leaves & sand cone, of which there were CORED at the end of the lake, and two in the centre—but the nuclei of the mounds were of Glacial Erosion in Norway. 225 . solid ice. By this lifting process, pockets of loose clayey sand were thrown on top of the morainic matter, producing thus the appear- ance of having been ploughed up by the glacier to even several yards beyond its termination, which has not been the case. Nowhere is there apparently more ploughing action, and yet little or none to be seen, than at Buarbree,which is advancing rap- idly against a high lateral mo- a raine. There is a large ridge gM- (Fig. 6) of stone upon a thin Sra to aoreet depoptting morsinie snout of the glacier, just as if the the false appearance of a glacial plough. ice were pushing under the boulders of earth. The glacier has a steep convex margin, from twenty to forty feet high, with many blocks and boulders upon it. These become detached, and, rolling down upon the lower tongues of ice, build up a ridge and leave a deep trough between it and the side of the glacier, and delay the melt- ing of the layer of ice beneath, which is too thin to do any plough- ing up of the moraine.

The lower surfaces of the ice-tongue were furrowed by the loose stones of the soft incoherent water-soaked moraine, into Which one’s foot would sink when stepping upon it. The moraine was being levelled by the constant dripping of the water from the whole under-surface of the advancing glacier. The glacier of Suphelle is the most remarkable of its kind, being a gigantic glacier rémanié. From the Jostedalsfond, which, near Zoo. Glacial Erosion in Norway. the head of the valley of Fjerland fjord, is 3,000 to 4,000 feet high, the clear, bluish ice falls over a precipice of dark rocks for about 1,000 feet, and at about 1,500 or 2,000 feet above the sea begins to re-form into a glacier extending down into and nearly across the valley of Fjærland for a distance of somewhat less than a mile, to a level of only 175 feet above the sea. The glacier is much crevassed, and covered and filled with debris. In fact, it was the most dirt-laden glacier seen—not excepting the Aar glacier in the Alps. This material is wholly derived from the side of the moun- tain, and is brought down by frosts, and more largely by the fall of ice as it dashes from one frost-cra¢ked rock to another. One of these great ice-avalanches I witnessed from the other side of the valley, fully a mile distant. Thousands of tons must have fallen at this time, but as the ice fell from rock to rock, it was con- verted into what, seen at the distance, appeared to be white dust. There are no considerable streams from the upper glacier, but from the rapidly melting glacier below the fall the volume of water laden with mud is large. As this glacier is not ploughing up, but levelling down the inequalities of its bed of loose material, we cannot suppose that the mud comes from any other than the dirt — upon and within the ice, and that obtained by the dripping water as it levels the terminal moraine. This is only one of the examples everywhere to be seen showing the erroneous estimate of glacier- erosion, when based upon the amount of mud carried down by the - streams flowing from the glaciers; for the debris is brought upon their surfaces by other than grinding action, and, as far as observa- tion goes, it is not derived from beneath them, at least, to any great extent. Although I have seen some of the sharp angles of the rocks at 2,000 feet above the fjords along the sides of the valleys, some- what rounded and scratched, yet the inequalities of the faces have not been removed by erosion of any kind. At numerous places in Norway, as well as in other countries, hammocks of rock rise abové or out of the glaciers, as the ice flows around them at lower levels, these channels having been deepened, not by glaciers, but by sub- glacial streams. Nowhere are the roches moutonnées so abundant as on the coast of Norway. In their more perfect form, they are not extensively developed along the coast at more than 250 feet above the sea. Glacial Erosion in Norway. 227 higher altitudes they are best seen about glacier-falls, farther up the valleys. But during the Pleistocene days, the coast has been raised several hundred feet, at least. The form of the hummocks is precisely like what may be seen in southeastern Missouri and other States south of the line of northern drift, or are described as occurring in Ceylon, Brazil and other tropical countries, to which only are added the scratches. The forms of these hummocks must be principally attributed to the atmospheric erosion of the crys- talline rocks where the debris has been swept away by currents or by ice. We see them more frequently swept clean upon the coasts of either cold or warm countries than in the interior, where the currents are only those from rain or local glaciers; for even the Sweeping beneath the glaciers is principally effected by drip- ping waters or streams. Professor Kjerulf, of the University of Christiania, than whom there is no better authority, regards the production of hummocks and their glaciation up to a height of 600 feet upon the coast of N orway, as the result of floating ice.’ The absence of transported boulders and striations upon the sur- face of many parts of the high plateaus of Norway is doubtless, in part, attributable to the ability of ice to flow around loose obstacles, and the frequent want of higher ridges to furnish material by their debris falling upon the ice to work through the mass afterwards. The faith in glaciers, as great erosive agents, has been so severely shaken that few geologists, who personally study those still exist- ing, now attribute to them greater power than that of removing soft materials, and of this power many others are sceptical, e.g., Pro- fessor Penck,? of the University of Vienna, who has been mis- quoted as having proved their great efficiency in eroding basins in hard rocks. To this scepticism, it seems to me that these notes must contribute; especially when glacial erosion is applied to the hypothetical excavation or modification of great lake-basins, and the transportation of the northern materials in the boulder clay over the broad plains of America, as there were no mountains of ade- quate height with peaks, or séracs, to supply the detritus sufficient to furnish the tops of the glaciers with all the boreal material of the drift, which “covers half a continent.” ie iscourse before Meeting of Scandinavian Naturalists, Copenhagen, * Geological Magazine, April, 1883. 228 : Glacial Erosion in Norway. In connection with this paper, the observations of Herr Payer and other arctic explorers are important. The snow-line of Franz Joseph Land descends to within a thousand feet of the sea, and the numerous glaciers discharge great quantities of icebergs as they move down into the ocean. Payer says: “ However diligently I look for them, I never saw unmistakable traces of grinding and polishing of rocks by glacier-action.” 1 Lieutenant Lockwood? found in central Grinnell Land a thick ice-cap, extending for a distance of from seventy to ninety miles, faced by an ice-wall of from 125 to 200 feet high, irrespective of topographical inequalities. It was free from rock debris, except in a valley confined by mountain-walls thousands of feet high. Along its foot there was almost an absence of morainic deposits, and even where present these were unimportant ridges. The general absence of rock and dirt in the arctic glaciers is a common subject of remark. The snow line in the high latitude of central Grinnell Land is 3,800 feet above the sea, and the glaciation of the rock about the adjacent Lake Hazen (500 feet above tide) is not recent. In Spitzbergen, where the snow-line is much higher, striated rocks, according to Nordenksjold, occur only below 1,000 feet.’ The same holds true for Labrador, where the scratches are confined to the lower thousand feet, although the mountains rise to 6,000 (Bell).* In the Antarctic regions, the officers of the “Challenger” remarked the absence of detritus in the icebergs and southern ice, although Wilkes and Ross saw rocks upon a few bergs. These last are supposed to have come from valleys in the voleanic moun- tains, Indeed, outside of valleys, explorers in high latitudes have not found, in the margins of such ice-caps visited, the tools capable of great erosion. The continental area of North America presents very much lower and less abrupt prominences than the reliefs of Greenland, Grinnell Land, Spitzbergen or Franz Joseph Land. Overhanging mountains seem to be necessary to supply glaciers with tools by which alone any abrasions can be accomplished, and 1 New Lands within the Arctic Circle, 1872-74.

Glacial Erosion in Norway. 229 these conditions belong only to valleys of great mountain ranges. However, there is one condition under which glaciers, when shod with graving tools, ought to be great eroders, viz., when their motion is much more rapid than the flow of land ice,—which is almost invariably less than three feet a day, under which condition, included stones commonly adhere by friction to the subjacent rocks, and cause the lower surfaces of the ice to be grooved. This condi- tion of extraordinarily rapid: movement has been seen at Jacobs- havn glacier in Greenland, where Professor Helland! found a velo- city of from forty to sixty feet a day. In Alaska, Lieutenant Schwatka? and Professor G. F. Wright? observed glacier move- ments of from forty to seventy feet a day. In these cases the gla- ciers are moving into the sea, and the new element of partial flota- tion or sliding, which does not belong to land glaciers, is here intro- duced. The great velocity of these glaciers is far beyond any observed ability of ice to flow as plastic bodies; consequently, one is led to conclude that, under partial flotation, stones may be held firmly as graving tools by glaciers. Hereby we are able to explain. the occurrence, in many Alpine valleys, of a greater glaciation than we see in progress to-day, as being due to glaciers rapidly advancing into fjords, during a period of partial submergence. The appeal to the greater magnitude of the glaciers, as produc- ing effects not now seen as the result of those of the present day, Seems to be begging the question, for the action of thicker glaciers differs from that of thinner in amount rather than in kind; for increased pressure, raising the temperature, increases the plasticity of the ice, as it is seldom if ever lower than freezing point. Con- Sequently it seems improbable that stones should be held more firmly in glaciers of thousands of feet in thickness than in those of | hundreds of feet. In addition, the friction between the stones held m the ice, and the surface of the subjacent rock, is proportionally increased by the greater weight of the glacier. Over the vast area of action, the work of floating or sea-ice, in some forms, is enormous. On the northern side of Hudson Strait, i a ords of North Greenland, Quart. Jour. Geo. Soc., 1877, A.

Dr. John Rae, who had very extensive arctic experiences, found that snow drifting over precipices into the sea resulted in the for- mation of bergs, sometimes a hundred feet thick, filled with the loose rock debris of the coast, and having the form of the shore where formed. Most of them break loose and drift away to melt or become stranded elsewhere. Greely describes the great momentum with which the floe-bergs come together. By their meeting the ice is crushed, and raised up into ridges fifty or sixty feet high. One cannot read carefully the results of the British Arctic Expe- dition of 1875-6 without being impressed with the erosive power of drifting ice, moving with a velocity never acquired by glaciers. Floe-bergs are pushed upon a shelving sea-bottom, until the ice has risen from twenty to sixty feet, after their first stranding in perhaps only from eight to twelve fathoms of water, although weighing tens of thousands of tons.? As the grounded floe-bergs are forced up the shelving sea-bot- - toms, ridges of earth and stones are pushed up in front of them. Floe-bergs which have been toppled over, thus showing their orig- inal bottoms, and also masses of pushed-up coast ice are found to be grooved and to contain angular stones with their exposed sur- faces scratched and polished. As the movement is greater than the velocity of glaciers flowing about obstacles, it is only natural to expect that the enclosed stones should be held firmly as graving tools, or be wrenched out owing to the brittleness of the ice under such great stress. In describing the ice action on the coast of Labrador, Professor H. Y. Hind says the “ pan-ice” (from five to twelve feet thick) is polishing the surfaces and sides of the rocky coast, and producing boulder clay. He says: “ When the pans are pressed on the coast by winds, they accommodate themselves to all the sinuosities of the shore line, and being pushed by the unfailing arctic current, which brings down a constant supply of floe ice, the pans rise over all the low lying parts of the Islands, grinding and polishing exposed shores, and rasping those that are steep-to. The pans are shoved over the flat surfaces of the Islands, and remove with irre- sistible force every obstacle which opposes their thrust, for the — 1 In Canadian Journal, Toronto, 1859. 2 British Arctic Expedition of 1875-76, Sir George Nares.

Similar results elsewhere have been frequently recorded, as those of Professor Milne in Newfoundland.” While the power of glaciers, under favorable conditions, to abrade and scratch rock surfaces, as “sand-paper” scratches “a cab- inet,” is not questioned ; yet these observations, in Norway and else- where in high latitudes, all confirm the correctness of the verdict given by many geologists—especially in Europe—who have had the opportunity of personally studying living glaciers, that the potency of land-glaciers to act as great eroding agents, capable of “planing down half a continent,” or ploughing out great valleys, or lake-basins, or even of greatly modifying them, is not only not proved, but most strongly negatived. Even the power of glaciers to abrade is reduced in many cases almost’ to zero. EDITORS’ TABLE. EDITORS: E. D. COPE AND J. S. KINGSLEY. European governments give more attention to the preservation of their ancient and prehistoric monuments than does the United States. This may arise, partly, from the increased interest upon that subject among their officials and people; or, partly, from the differences in our form of government. Whatever may be the Cause, our government and our people, unless they improve their present methods in this direction, will find cause for regret in — after years, when the prehistoric monuments of our country shall have been destroyed and their contents scattered without a record, when it will be too late to remedy the neglect. _ The French government has passed several laws upon this sub- Ject. It has established a commission under the direction of the Minister of Public Instruction and Fine Arts, charged with the duty of the supervision of these monuments throughout the Republic, These laws only provided for the procuration of the title to land by gift or purchase. Some of the land-holders took ' Notes on Some Geological Features of the Northeastern Coast of Labrador, Can. Nat. 1878. ce and Ice Action, Newfoundland, Geol. Mag., 1876. 232 Recent Literature. advantage of this and increased their price beyond what was fair and reasonable, and now the French government has met them with a decree, authorizing the State to acquire by expropriation the land on which these monuments are situated, principally in the Commune of Carnac, Department of Morlehan. | Many of the monuments have already been acquired ; have been restored to their original condition, surrounded by a fence, where practicable, for the necessary preservation. This has been done under the supervision of M. Felix Gaillard, archeologist of Plouharnel. Those to be added under the decree, above mentioned, will be the great alignments of Menec, of Kermario and of Kerlescan ; the great tumulus of Saint-Michel, that of Moustier, of Crucuny and of Kerlescan. Also six Menhirs and six Dolmens. It is believed that under the operation of this law the present proprietors will yield, and that the State will acquire, by purchase, all the monuments of this kind within the commune. When these are restored and put in proper condition, this commune will be one of the most attractive in all France, and the American tourist, interested in prehistoric archeology, will feel it as much a necessity to visit it as to visit Paris.—T. W. RECENT LITERATURE. | A Review or Mr. LYDEKKER’S ARRANGEMENT OF THE Mesozorc MAmMaALtIA (Cat. Foss. Mamm., British Museum, Part V., 1887).—Mr. Lydekker places all the Mesozoic mammalia among the Marsupialia, not admitting that there is sufficient weight in the close analogy between the dentition of the Stylodontide and Chrysochloridz to support a reference of this family to the Insec- tivora. The genera included under the sub-order Multituberculata of Cope are provisionally embraced in the Diprotodontia (p. 195,) while all the remaining forms with numerous small incisors are placed with the Polyprotodontia. I agree with the author that the systematic position of the Multituberculata forms, such as Plagiau- lax, Tritylodon and Polymastodon must be left, in a measure, pro- visional until additional material is obtained ; but at present, in my opinion, the balance of evidence necessitates their separation from the Diprotodonts. The most striking feature of both these groups is the hypertrophy of a pair of incisors in each jaw; but, so far as a close comparison of these incisors in the fossil and recent forms is Recent Literature. 233 possible, it supports the conjecture that these teeth in the two groups are neither homologous nor homodynamous, although bearing a superficial analogy.! ) regards homology, in all the Quaternary and recent Dip- rodonts it is the median incisor which is hypertrophied ; whereas, in the Mesozoic genera—in which the mode of reduction has been observed—the second incisor, or, rather, one of the lateral incisors is hypertrophied. In the Bolodontide, as demonstrated by Marsh in his observations upon Allodon, the median incisor is reduced and the second incisor is hypertrophied. In Tritylodont there are two incisors : the outermost is close to the maxillary suture; the hyper- trophied incisor is close in front of this and widely separate from its opposite fellow, indicating that if this genus is descended froma form with three or four incisors (asa comparison with Bolodon ren- ders probable), it is again the median incisor which has disappeared. Ve have no further evidence bearing upon this point, so it will be of importance to observe which of the incisors is hypertrophied in Plagiaulax? Plagiaulacide. Professor Marsh recently called my attention to the wearing of the posterior face of the large upper incisor of Allo- ‘don by the tip of the lower tooth. This interference forces the jaw wards as it ascends by a mechanism similar to that in the ro- dents, as demonstrated by Cope’ It has effected a rapid reduction of the other incisors, as witnessed in Tritylodon and on; a total reduction, as witnessed in Polymastodon and Plagiaulax. In contrast with these genera, the recent Diprotodonts present, for the Most part, three upper incisors ; while the reduction of all, except $° median incisors and the fore-and-aft grinding motion, is con- to a single family, the Phascolomyide. a 3.)

In my opinion, the Multituberculata will finally prove entirely distinct from the Diprotodonts and representative of a phylum of genera which reached too great a degree of specialization at the close of the- Cretaceous to survive until the recent period. Thylacoleo was placed as the latest representative of the Plagiaulax line by Owen, and,. later, by Cope; but this view is not shared by Lydekker, who places it near the Phalangistide. (Op. cit., p. 188.) ` e family arrangement is the same as that proposed by Cope and adopted by myself,! with the addition of the Bolodontide. We are surprised to find Microlestes placed in the latter family instead of in the Plagiaulacide ; for the type-molars bear only a superficial resemblance to those of Bolodon, and closely approach those o Plagiaulaz. The Polyprotodont genera are provisionally placed by Lydekker in five distinct families, under the Marsupialia Polyprotodontia.. In the arrangement of these genera the author has been at a great disadvantage in not having been able to study the types of the Yale College collection, in which the molars are exposed upon both the inner and outer surfaces, and thus fails to recognize the distinctive features of the molars in many instances. But this will not explain his separation of Amphilestes and Phascolotherium from the Tricono- don line and their union with such diverse forms as Amphitherium, Achyrodon and Peramus. 1.) In the Amphitheriidee (which embraces, among others, the five genera just mentioned) we are surprised to find (p. 274) that Peras- ax is made a synonym of Amblotherium. This is explained ina footnote (p. 274), in which a small inner cusp is described upon the ower molars of A. soricinwm—an interesting observation if correct, use it is entirely opposed to the observations of Owen (Mesozoic: Mammalia, 1871) and the writer (1886). According to the latter, eraspalax has prominent internal cusps, separate from the internal —a type of molar found only in the type maxilla of Peralestes. The lower jaw of Peralestes, type of Phascolestes (Owen), is also united with Amblotherium. This is more probable, as the outer face of neither genus is certainly known, and the inner faces are very simi- lar ; but if Amblotherium and Phascolestes are alike, both must be re- 1On the Bireta and Classification of the Mesozoic Mammalia. Ab- stract, Proc. Phila. Acad., June, 1887. 2 Am. Jour. Se. and Arts, April, 1887. Recent Literature. 235 that when the outer faces of the lower molars are known they will also prove to be of the Stylodon type. The Amphitheriide is thus made a miscellaneous family, to embrace genera with lower molars —multicuspidate, tricuspidate, or differentiated into a blade and talon.” “ The difference in the character of the lower molars is not greater than obtaining in the Dasyuride” (p. 269). While this may be true, it does not afford sufficient ground for separating Phascolotherium and Amphilestes from genera with three- lobed molars (Triconodon) and placing them with genera with two- lobed molars (Amphitherium and Peramus). The American genus ` Dromatherium, with unpaired fangs, is also placed in this family, ' adding to its heterogeneous character. (2.) Triconodontide, Triconodon, probably by a typographical error, is stated to have no internal cingulum upon its molars (p- 257). The cingulum is one of the most characteristic features of the molars, and establishes the close homology which exists between the Triconodon, Phascolotherium, Amphilestes and Spalacotherium molars, indicating their phylogenetic relation with many mandibular and dental characters in common, that they formed a series of primi- tive Carnivora. Lydekker follows Marsh® and Osborn® in making scotherium the type of a distinct family, the (3) Spalacotheriide. +he inward rotation of the lateral cusps characteristic of this genus ìs begun in Phascolotherium and extended in Tinodon, affording tran- sitions ; so that, with the resemblances of the mandible and pre- molars, it is probable that this genus is an offshoot of the Tricono- type. At all events, I cannot now discover family characters. sufficient to separate it from the Triconodontide. I cannot share the opinion (p. 292) that these molars are of the Chrysochloris type; h are rather of a primitive tubercular, sectorial order, leading to . sectorial triangle of the Didelphys molar. Upon page 294 we a. Peralestes (type maxilla, Owen) also placed in this family, and “eae A separated as a genus from S. tricuspidens. The molars i genus, with separate external and internal cusps, are widely np from those of Spalacotherium, the upper molars of which mi probably be found to exactly reverse the pattern of the lower. 'S genus seems, therefore, to be identical with Peraspalax. (+) It is in Stylodon, type of the Stylodontide, that we find the ay omologue of the Chrysochloris molar® and a representative qro ttue line of Insectivora. Lydekker, although in possession of : ay s description of the lower molars of the closely allied genus éj jo'estes, describes the lower molars of the Stylodontidæ as simply nical (p. 290). We have positively no grounds for referring this 1 I os » It is probable that several specimens which were referred to Cenblotherium by Owen really balone to Stylodon—e.g., A. mustelula Fig. 2, Owen’s Memoirs).

No Marsupial presents an analogous dentition. Percmeles, it is true, bears a similar relation to Tupaia ; but some stress may be laid upon the fact that the Stylodon and Chrysochloris are the only known examples of this type of molar. As Mr. Lydekker himself indicates by his frequent use of the word provisional, we are certainly not in a position to reach final conclusions in regard to the classification of the greater number of these Mesozoic genera ; and this review of the related portion of this valuable catalogue is intended, in large part, to suggest further in- quiry, rather than as an expression of final opinion on my own part. —Henry F. Osborn. SEEBOHM ON THE CHARADRIIÐÆ.!—This is another of the handsomely illustrated works of large folio with which the orni- thologists of Britain from time to time delight the scientific world, and all other lovers of nature as well. While the present publica- tion does not pretend to be a complete descriptive monograph, diag- nostic characters and figures of species and sub-species are given, which are quite sufficient for the determination of the known members, at least, of the family. The scope of the work is indi- cated by the fact that it embraces as Charadriide the tribe Limi- cale of many authors. Especial attention is given, as the title indicates, to the geographical distribution of the members of the family, with especial reference to their evolution. ; The first chapter is occupied with the classification of birds im general. The second is devoted to evolution in general. The author here distinctly affirms the doctrine that Natural Selection never originated anything, and he ranges himself on the side of the Neolamarckian school, although he does not say so in precise terms. In this matter he shows himself to be much more perspi- cacious than those of his countrymen who, like Mr. Romanes, regard this view of the subject as “transparently fallacious {Romanes in review of Schurman in Nature, Feb., 1888). But we take issue with Mr. Seebohm in his expression of evolution in taxonomy. Like Schlosser, he believes that “ natural” groups must represent phylogenetic series, and he believes these series tO be expressed by the totality of the animals’ characters. Thus characters of the specific grade generally in his system take pre- cedence of those usually regarded as generic and even higher. We have objected to this doctrine on various grounds, especially in our essay on The Origin of Genera.? First, because generic characters probably express more in phylogeny than specific; second, iuse specific characters consist of an aggregate of single charac- ters, and each has had a history independent of the others, 50 that 1 The Geographical Distribution of the Charadriide, by Henry See- bohm.

Such a system may be called artificial, but it is the only system with defi- nitions that we can ever have. As a consequence of his views on this subject, Mr. Seebohm combines species with three toes in the same genus as those with four, and species-with an expanded bill (Eurynorhynchus) with species without such expansion (Tringa). e most American zoologists, Mr. Seebohm finds it necessary to adopt sub-specific names, or the trinomial system, for protean groups. In this way the relations of the forms are well expressed throughout this work. We wonder when the wealthier men of the United States will begin to devote some of their spare time and means to the produc- tion es works like this admirable combination of science and art.. — . . .

GEOGRAPHY AND TRAVEL: Asta, Erc.—Norru Bornro.—The account of explorations in North Borneo, by D. D. Daly, published, with map, in the Pro- ceedings of the Royal Geographical Society (January, 1888), is a valuable addition to current knowledge of the great island, a portion of which has recently fallen under British na The most southerly point of British North Borneo is 3° 52” N.; the most northerly (the northern point of Banguey Island), 7° 25’ A E the most westerly, 115° 20’ E.; the most easterly, 119° 16’ E. The area is computed at 31 000 square miles, the seaboard at 700 miles, and the population at 150,000. The principle land-locked 1 Edited by W. N.

Tobacco is the principal crop yet cultivated, and Chinese contract labor furnishes the means, for the climate is not one in which the white man can perform hard work in the open air. The larger half of the island belongs to the Dutch, who are not taking steps to encourage the opening up of their territory. The remainder consists of British North Borneo, Sarawak, and the small independent sultanate of Brunei. Mr. Daly (August, 1884) entered the Kinabatangan, the largest navigable river of the territory, in a steam-launch. Malapi, about half a degree up this river, is the depot for the edible birds’ nests- brought from the Gomanton caves, about twelve miles farther north. The value of the nests collected is $25,000 per annum. The height of one of the vaults of these caves has been estimated at 900 feet, and a steady column of Collocalias has been seen to fly from one of the apertures for forty-five minutes. All the birds’ nests caves (there are many others) are in isolated mountains of limestone in a country of secondary formation. The settlements along this river and its tributary, the Lokan, which rises near Mount Kinabalu (13,680 feet), seem to be flourishing, durians, langsat, rambutans, mangoes, limes, oranges, lichee and pulasans saya fields. Higher up live the Muruts, who wear no clothes, and are still, where not yet reached by British influence, addicted to head- hunting. The Murut Chief Zalmiboh put his house at Mr. Daly’s disposal. It was fifty feet square, and very clean ; but from the rafters dangled fifty human heads and pieces of human bones. Geography and Travel. 241 Mr. Daly was himself instrumental in making the Muruts and the Peluans of the interior swear to be at peace with each other, and to follow the law of the British North Borneo Company, beneath whose flag they swore friendship. THE Zones oF TIBET. — General S. T. Walker, after the read- ing of Mr. Carey’s account of his travels in Central Asia, before the Royal Geographical Society, stated that Tibet might be broadly divided into three zones, which increase in altitude from south to north ; a southern zone, 10,000 to 12,000 feet above the sea, con- taining L’hasa and all the towns and villages of the settled popula- tion; a middle zone, 12,000 to 14,500 feet high, comprising the pasture lands of the nomad Bodpas, or pure Tibetans; and a northern zone, 14,000 to 17,500 feet above the sea, partly occupied at certain seasons by Turkic and Mongolian nomads, but mostly abandoned to wild animals. It was this Chang-Tang or northern plain that Mr. Carey had crossed in various parts during his Journey to and from Turkestan. Arrica.— LAKE SHIRWA. — According to the Rev. A. Heth- erwick, there is now no communication between Lake Shirwa, or Chirwa and the Lujenda River. It is very evident that at one time e Shirwa covered the broad flat plain to the west of it, was united to Lake Chinta, the present head of the Lujenda. Gradually the waters fell, and the sandy ridge of Chezomoni appeared. The present lake is very shallow, and grows smaller yearly, Its area is about 350 square miles. SETE Kama. — Sete Kama, on ihe west coast of Africa, is the name given to the district extending from 2° 28’ to 2° 45’ south latitude. European factories are scattered along the beach for about three miles. All the factories have sub-stations on the Ndago lagoon, the old mouth of which has been silted up for three years. It appears that the land is gaining on the sea, for at Ngoné, a mile from the shore, Mr. Walker found an old ship’s anchor. Ndago lagoon is of great extent. The Balombo, who inhabit Sete Kama, have a week of four days, as do also some other tribes on the west coast. Grocrapnican News. — King Menelik of Shoa has recently annexed Harar, not many years since a part of the Egyptian pos- Sessions. The French ‘traveller Rimbaud has returned to the Pa from Shoa via Harar, thus avoiding the dangerous route hrough the Danakff country.

Mimic EARTHQUAKE NEAR AKRON, O.—A district of coun- try lying about five miles south of Akron, O., was on the night between Thursday, February 9th, and Friday, February 10th, the scene of a commotion that well simulated an earthquake on a small scale. About nine o’clock in the evening a smart shock disturbed the inhabitants and caused much consternation, which was intensi- fied when between two and three the following morning a severer one, accompanied by a loud noise, as of an explosion, awoke the sleepers by shaking the houses and cracking the walls of some of them. When daylight came several long clefts in the ground were discovered, furnishing evidence of some subterranean disturbance during the night. Similar phenomena occurred almost in the same spot in 1882 and 1883. At that time a cleft from two hundred to three hundred feet long was formed, which crossed a road, marking its course with a furrow, such as that made by a plough. This crack was not more than an inch or two in width, but was sounded with a stick to the depth of several feet (some say fifteen or twenty). It passed under ~ a house, cracking the cellar-wall. The noise accompanying it was likened by some of those who heard it toa cannon fired in the cellar. The explosion of Friday morning last (February 10) was heard by several persons in Akron, at a distance of about five miles. The writer visited the spot last summer, at the request of a gen- tleman who had leased several farms, with the intention of drilling for gas. On making inquiry of one of the oldest residents, he learned that an earlier event of the same kind took place about twenty-five years ago, but could get no details. The phenomena pointed, not to seismic causes, but to subterra- nean explosions, presumably of gas. The ground is clay an pa moraine matter, probably not less than a hundred feet m depth. , Kile account differs somewhat in the details: “ After the ex- plosion in 1882, then the fissures, some of them nearly half a mile long, radiated to the top of a rise of ground. Mr. Thornton dug 4 hole nine (9) feet deep at the point where the fissures crossed OF formed a centre, and at that depth found the cleft in the earth as pronounced as it was at the surface.” So far as it is possible to determine it, the cause of the prong tion is due to the presence of a certain, perhaps a small, amount 0 natural gas, which, in ordinary circumstances, escapes unnoticed. But when the ground is frozen (and all these explosions have pga red in the winter) the gas is unable to ooze through the soil Geology and Paleontology. 243 accumulates below the frozen crust, until its elasticity becomes suffi- cient to burst it; hence the explosion, the shock, and the cracks in the ground. At the outburst in 1883 several of these cracks could be seen radiating from a central point in a field and extending to different distances. One of the spectators says these clefts divided the field into half or quarter-acre pieces. Similar results followed the late explosion. I have not seen the place since, but learn that the fis- _< very soon closed, or were filled up in consequence of a rapid thaw. “One peculiar feature is that while former disturbances rent greater fissures and were accompanied by much greater damage to property than the recent ones, yet, so far as is known, none of the former explosions was heard or felt in this city.” It would be interesting to inquire if any similar events are on record elsewhere in regions yielding natural gas. Perhaps this note may be the means of calling out such cases if they exist. It may at first sight appear as if so powerful explosions and ocks must indicate natural gas in considerable quantity. But when we reflect that the pressure in a well of small yield rapidly rises to a high figure when the bore-hole is closed, we see that such an inference is not safe. No other indications of gas are yet known in the immediate neighborhood, as would probably be the case if a supply were accessible.— EH. W. Claypole. GEOLOGICAL NEws.—PRIMORDIAL.—It is stated that vestiges of the primordial fauna, hitherto unknown in France, haye been discovered by M. Bergeron in the Black mountain (la Montagne oire) of Herault. Conocoryphe and Paradoxides are represented by fine examples. Devontan.—Mr. A. S. Woodward (P. Z. 8., 1887) notes the presence of a canal-system, evidently sensory, in the shields of Pteraspidians, He believes these to representa “ lateral-line” system. B. Stiirtz (Palwontographiea, Band 32) describes several new coninodernis from the middle strata of the Lower Devonian upon r e Rhine. Ophiurella primigenia, Furcaster palæozoicus, Bun- enbachia beneckei, and B. grandis are the new Ophiuroids and related forms described ; the star-fishes include an Astropecten, alastropecten and Eoluidia, a Loriolaster and a Palasteriscus. Gas A. Penecke has contributed to the Zeitschrift der Deutschen - th logischen Gessellschaft for 1887 an account of the fauna and e age of some palseozoic coral reefs in the eastern Alps. He J. Walker discusses the structure of Crinoids, with special erence to the species found in the Solenhofer slates and the 244 General Notes.

CaRBONIFEROUS.—Mr. Kliver describes (Palewontographica, Band. 32) various arthropod remains discovered in carboniferous strata of Saarbrucken and Wettin-Libejiiner. The species include an Ectoblattina, two species of Termes, a Dictyoneura, and an Acridites, Prof. Boyd Dawkins states his conviction that the sound- ings for the proposed tunnel across the Straits of Dover will bring to light the existence of vast beds of coal, connected, on the one hand, with the coal measures of Belgium and the north of France, and, on the other, with those of Wales and Somerset- shire (England). PERMIAN.—The second part of Dr. Anton Fritsch’s “ Fauna der Gaskohle and der Kalksteine der Perm-formation” of Bohemia, has been published. These strata rest upon Silurian rocks. The coals, clays, and ironstones have a carboniferous facies, and the con- formable limestones are believed to be true Permian. “ The palæon- tological evidence,” says the reviewer in Nature, “is somewhat anomalous in the views of purely British fossilists, but it s very forcibly and in a most suggestive manner to the students of the Gondwana formation of Hindustan.” ‘Two new species O Dendrerpeton are described, and a family Dendrerpetonide 18 characterized. M. Bayle has found two entire specimens of Gaudry’s Actinodon frossardi in the Permian deposits at Telots. Gau- dry’s descriptions were based upon fragments discovered near Antun. Actinodon was probably a carnivorons reptile about 25 feet long, living more upon land than in the water, and formed for gliding serpentine movements. The stage of evolution presen by this reptile is comparable, according to M. Gaudry, to that of the Chelydosaurus of Bohemia, the Zygosaurus of Saxony an Russia, the Platyops of Russia, the Gondwanosaurus of Hin ustaD, and the Trimerorhachis and Eryops of Texas. Its scales were disposed in chevrons, its vertebre were formed of separated pieces, and its large ribs gave attachment to ample muscles.

Trras AND Jurassic. — The German Paleontographica (Stuttgart, 1886) contains a gevlogical and paleontological mono- graph of the “ Vilser” Alps, with especial reference to the Brachio- poda. The work is illustrated with fifteen plates and a map of the region. The strata belong to the Trias and Jura. The general facies of the fauna, especially that of the Brachiopoda, is Mediter- ba rather than Central European. Several new species are escribed. The Asterids of the White Jura of Swabia and Franconia, with researches into the structure of the Echinodermata and the calcareous skeleton of the Asteriadæ, form the subject of the last memoir in Volume 32 of Paleontographica. new Iguanodon, J. dawsonii, has been described by Mr. R. Lydekker from the Wealden strata of the Isle of Wight. G. C. Laube and G. Bruder describe the Ammonites of the Bohemian chalk in Band. 38 of Paleontographica. Eleven Mr. A. S. Woodward (P. Z. 8., 1887) refers the genus Rhacolepis, Agassiz, to the neighborhood of the Clupeidæ, and places it near Elops. It seems to have been one of the fore- runners of the latter to have been developed in Jurassic times, and to have swarmed in Cretaceous seas. The fossils are “ommon in the Serra de Araripe, in Northern Brazil. i Cretacrous.—Herr Car] Diener, in a contribution to the know- edge of the Cretaceous formation of Syria (Zeit. d. Deutschen geol., ges. 1887) gives a table of subdivisions, placing the Lebanon chalk ky in the Turonian and partly in the Cenomanian and the Arâja- kstein at the bottom of the series. Bea S.

He distinguishes four—M. dixoni, M. striatus, M. toliapicus, and M. labidens, new species, the last from the Brackleshem Beds. Mr. A. S. Woodward (P. Z. S., 1887) asserts that a fossil representative of Chlamydoselachus, Garman, from the Pliocene beds of Oreiano in Tuscany, was described and figured (under another name) by Mr. R. Lawley in 1876. He suggests that this species be named C. lawleyi. The figures will be found in “ Nuovi Studi sopra di Peci ed albri Vertebrati fossili delle cobline Toscane,” di Roberto Lawley, Florence, 1876. Dr. O. Roger describes (Palwontographica, vol. 32) some teeth of Dinotherium bavaricum H. v. Meyer, discovered in the valley of the Zusam, a small tributary to the Danube. M. Lemoine has discovered in the eocene beds near Rheims, the teeth, jaws, etc., of five generic types of carnivora. Th first of these equals Arctocyon in size, and seems analogous to Dissacus Cope. The two molars preceding the last show a com- mencement of the division of the anterior cusp of the tooth. Another type approaches Proviverra; another is named Tricus- piodon from the three cusps which in the molar teeth precede a very small heel, and recalls the Spalacotherium of the Prexbeek beds while another (Procynictis) has very singular molars, yet presents analogies with Amblotherium and Peramus of Owen. These forms tend to link the mesozoic with more recent faunas. M. Gaudry has recently announced to the Acad. de Sciences of Paris the discovery of a gigantic tortoise in the middle Pliocene of Perpignan. The head, limbs, and part of the neck have been recovered from the encasing hard rock. In size this tortoise exceeds any living species, since the carapace is 1.20 metre long and a metre wide. The carapace of the Aldabra tortoise ( Testudo elephantina) scarcely reaches a length of one metre. The only other tertiary or later fossil tortoises equalling in size the Testudo perpiniana, an that discovered twenty years since by M. Gaudry in the miocene of Mt. Lebanon, and a sub-fossil species (7. grandidieri) brought from Madagascar by M. Grandidier. T. perpiniana seems to have more affinity to Testudo irrepta and triseriata of Mauritius than to any others, since like them it has a depressed smooth carapace, relatively slender limbs, ete. In the great development of its sternum, however, it approaches the Atdabra tortoise. Mr. A. Bell (Geol.

He attributes the elevation of the platform of Lake Titicaca to volcanic action, and assigns it to quaternary time. MINERALOGY AND PETROGRAPHY.! PETROGRAPHICAL News.—In an article on the contact phenomena presented by certain Scottish olivine diabases, cutting sandstones and shales, Stecher ? gives us some new and important ideas on the general subject of contact action. These olivine diabases are carefully described in all their varieties. Skeleton crystals of apa- tite, corroded augites, twinned plagioclase, dihexahedra of quartz, and various rare minerals are noted in them. The quartz shows anomalous action in polarized light, and is peculiar in that its hex- agonal sections are seen under crossed nicols to consist of a kernel of quartz substance, surrounded by a rim of calcite. In some in- stances the olivine yields analcite by alteration. The most interest- ing portion of the paper is that which treats of the endogenous changes which have taken place in the dykes under the influence of the intruded rocks. Although more acid on their edges and in the neighborhood of sandstone inclusions, it was found that only in these places in the dykes is there any considerable development of olivine in perfect crystals. At a somewhat greater distance from the contact, the olivine becomes more skeleton-like in form. In the centre of e dykes it is absent. This is accounted for by Stecher in sup- posing that the material of the dykes cooled quickly on its and thus preserved in their entirety the olivine which had already crystallized before the rock reached the surface of the earth. As the inner portion cooled more gradually, the. magma became more acid as it dissolved material from the sandstone and de PS torn from its walls, and thus re-dissolved the olivine, and then solidified under the changed conditions.—In contrast to the results obtained by Stecher, in which the effect of contact action is seen only in the eruptive rock, are those obtained by Greimiin his studies of the phenomena presented by the intrusion of the Upper-Devon- , Edited by Dr. W.

In this case the diabase itself has suf- fered little alteration, but the schists show to a greater or less degree the effects of metamorphic action. The unaltered schists are com- posed of quartz, muscovite, hematite and other iron oxides, in which are lenticular areas and beds of calcite. Where altered they are seen to contain an isotropic groundmass in which are quartz, mica and a chloritic mineral. In addition to these the two newly formed minerals spinel and andalusite occur. In discussing his re- sults, Greim concludes that the diabase supplied sodium and iron to the schists, which then underwent the alteration which is supposed by Rosenbusch to be characteristic of deep-seated metamorphism. —A third excellent paper on contact phenomena is that communi- cated by Riidemann. ‘This author has investigated the effect of the granite occurring at Reuth, near Gefrees, in the Fichtelgebirge, upon the clay slates, phyllites and amphibolites through which it cuts. He carefully describes the knotty-schists (Knoten-schiefer), the chiastolite and andalusite schists, and the hornfels resulting from this action, and reaches some general conclusions relative to the way in which an eruptive rock acts in the production-of what are commonly known as contact rocks. In both phyllites and clay slates the first result of the metamorphic action is the concentration of certain of their constituents to form the spots (Knoten). In this stage there is little or no other change to be detected. The next stage is characterized by the formation of por- phyritic crystals, chiastolite in the clay slates of Reuth and other localities, and biotite in the case of phyllites (Garbenschiefer). In the first case the andalusite owes its origin to the alteration of a light green chloritic mineral (griimbelite). In the case of the phyllites biotite replaces chlorite. In the third stage the end pro- duct of the alteration both of clay slates and phyllites is hornfels. This is a crystalline rock composed of quartz, biotite, muscovite and andalusite grains. Assuming that these changes in the sedi- mentary beds are directly connected with the presence of the large granite mass which they surround, the author supposes the earlier stages in the alteration to be due to the intense heating to which the rocks were subjected at the time of their intrusion by the granite. This is shown by the fact that in different beds different contact minerals have been produced, while the composition of the altered rocks corresponds to that of the corresponding unaltered beds from which they were derived. To account for the formation of horn- fels, and the minerals so commonly found in it, Riidemann sup- poses the energetic action of hot waters upon the constituents of the fragmental rocks. The paper is exceedingly well written, and con- tains very much of interest.—In connection with the discussion of 1 Neues Jahrb. f. Min. ete., B. B. v., p. 648.. Mineralogy and Petrography. 249 contact phenomena, a late paper by Hussak,' on the origin of the spots in altered sedimentary rocks (Knoten-and Frucht-schiefer) is worthy of close study. Rosenbusch regards these spots as due to the aggregation of the pigment, which was distributed evenly through- out the fragmental rocks before their intrusion by the eruptives. In certain cases he supposes these aggregations to pass by recrystal- lization into chiastolite and andalusite. Ward regards them as un- developed andalusites. Other writers have described them as pos- sessing characteristics which indicate their close connection with other mineral species. Hussak, upon examining the spotted schists. from Tirpersdorf, Saxony and Hlinsko, Bohemia, found that the darker portions of the altered schists possess properties which can only be explained by supposing them to be the remains of altered cordierite, in the case of the Saxon rocks, and of altered chiastolites and andalusites in the rocks from Bohemia. number of new forms were detected, which ad known make a total of seventy-five thus far identified on the pendent mineral species distinct from manganite.

The mineral is insoluble in hydrochloric acid. It dissolves slowly in sere, sulphuric acid, but rapidly in a mixture of sulphuric an hydrochloric acids.

Some of the crystals from this locality “ are as pellucid as red Iceland span and show the same double refraction.” The same author? describes some curious groups of quartz crystals from the vicinity of the town of Pinal, Pinal CO., Arizona. Six or more little crystals of the usual form are so arranged as to form a hollow cylinder, with the general outline of a large quartz crystal. e also mentions a white opaque variety of hydrophane from Colo- rado, which is remarkable in that it can absorb more than its own volume of water. When wet it is perfectly transparent.—Mr. R. B. Riggs’ of the United States Geological Survey has published the results of the analyses of a suite of tourmaline crystals from vari- ous localities. The conclusions reached by Mr. Riggs, after an immense amount of very careful work, are of very great interest as establishing with a good deal of accuracy the composition of this complicated group of minerals. The figures obtained lead the au- thor to regard tourmaline as a simple boro-silicate with the genera formula R, Bo, (S i O,),, which for the three types recognized by him became : I. Lithia tourmaline = 12 SiO, 3B,O, 4H,O. 8Ae¢,0,; 2 {NaLi),O. II. Iron tourmaline = 12 SiO,. 3 B,O,. 4H,o. 7AE,O,. 4 Fe-O. Na,O. - III. Magnesia tourmaline =.12 SiO, 3B,0,. 4H,O. 5AE,O; 2% MgO. 3 Na,O It is interesting to note that while the color of the iron and mag- nésian varieties depends upon the amount of iron in their composi- tions, in the case of the lithium varities, containing manganese and iron, it depends upon the ratio between the manganese and iron constituent, being colorless, pink or pale green when the amounts of these are equal, red when manganese is in excess, and green Or blue when iron is in larger quantity. 1 Amer.

PLANCHON’s REVISION OF THE AMPELIDE®.—In the recently received Part 2 of the fifth volume of De Candolle’s Monogra- hie Phanerogamarum, J. E. Planchon makes a thorough revision of the Ampelideæ. Such considerable changes are introduced in the ony that it may be well to present a summary of the work ere. The order is restricted somewhat from the limits assigned it by Bentham and Hooker in the Genera Plantarum, by the exclusion of Leea with its twenty species or so. The remaining species (386) are distributed among ten genera, instead of two, as in the Genera Plantarum. It will be remembered that in the latter work the authors reduced almost everything to one genus—Vitis. Planchon, on the contrary, divides the old genera and constructs several new ones. The following abridged conspectus of the genera will serve to show their principal characters, and the method pursued in differentiating them :— Flowers polygamo-diccious; petals 5, cohering; style (short) conical; hypogynous glands 5; berries two-celled, 2-4 seeded ; climbing shrubs with simple, variously lobed leaves......... .

When the plant has reached something adapted to its needs as a parasite— Forsythia viridissima in our observations—it winds about it loosely at first, then after the manner of a tendril quickly contracts, bring- ing its coils close to the host, that the haustoria may penetrate the bark. This contraction pulls up the root, leaving it loosely hang- ing by the host, sometimes half an inch above the soil, where it withers and dries.—Henrietta E. Haaker, Botanical Lab., Mt. Holyoke Sem., Feb. 17, 1888. THE FossIıL FORESTS OF THE YELLOWSTONE NATIONAL PARK. —At the February meeting of the Washington Biological Society, Professor Knowlton gave an aceount of a visit to these fossil forests, which are located mostly in the northeastern portion of the park, a locality rarely visited by tourists. The largest isolated trunk seen was twenty-six feet in circumference, without the bark, and twelve feet in height. In the edge of a cliff trunks are exposed to a height of thirty feet. Specimens from about 300 of these trees are now being identified. They represent about twenty species, including the genera Pinus, Sequoia, and Taxus. New SPECIES or Urepinex.—At the February meeting of the Washington Biological Society a paper was read by B. T. Galloway describing seven new western Uredinew collected by Tracy and Evans. in 1887, and named by Tracy and Galloway. They were Uromyces arizonica, Puccinia fragilis, Puccinia caulicola, Puccina vertisepta, Æcidium draba, Æcidium heliotropii, and Æcidium ellisite It is to be hoped that the authors will also publish their descrip- tions in the Journal of Mycology, in which, in our opinion, all descriptions of our fungi ought to appear. BoranicaL News.—The announcement is made that Dr. Lorenzo G. Yates, of Santa Barbara, California, with the assistance of J. G. Baker, of Kew (England), will soon bring out a book entitled « All Known Ferns,” which will consist of an alphabetical list Zoology. 255 (generic and specific) of all the ferns of the world. It is not to include descriptions, but references are to be given in every instance to descriptions. Synonyms will be given, and the distribution of every species will be indicated. It promises to be a very useful book. Miss Jane H. Newell, of Cambridge, Mass., has begun the publication, in parts, of a little work to be called “Outlines of ns in Botany,” designed to be of use to teachers who wish to do more than follow the old methods of botanical teaching. The lessons outlined “are suitable for children of twelve years of age and upwards.” Directions are given for raising seedlings, and for making observations upon them in their growth. ‘The parts before us are privately printed, in order to have them. tested by other teachers before publication. They may be obtained by any teacher who will use them experimentally, by addressing the author at 175 Brattle street, Cambridge. DeBary’s Lectures upon Bacteria, English translation, has been received from Macmillan & Co. It is a small work, of a sufficiently popular style to enable any well- educated man to get a good idea of the subject. A fuller notice will appear later. Detmer’s Pflanzenphysiologische Praktikum,, from Gustav Fischer, of Jena, promises to be a most valuable book in the botanical laboratory. It is an octavo of 352 pages, and is illustrated with 131 wood-cuts. Dawson’s “ Geological History of Plants” is an interesting volume of the International Scientific Series, which has just appeared. The style is popular, but the treatment is thoroughly scientific. ZOOLOGY. : again J differentiating a male and female pronucleus.

An Oxydromus grandis had from 40,000 to 50,000 descendants while a pair were indulging in a single conju- gation. It is a source of destruction, not of the multiplication -of individuals. The riddle was solved by a long series of careful observations. In November, 1885, M. Maupas isolated a Stylonychia pustulata, and observed its generations until March, 1886. By that time there had been 215 fissiparous generations. But at that time the colony gave in; the individuals had lost the powers of nutrition and repro- duction. Individuals removed at various stages, however, had conjugated with individuals of a different origin. The same conjugations had been effected with members removed to other families. This was done till the 130th generation, and till then all the conjugations were fertile. About the 180th generation individ- uals of the same family which had not hitherto been in contact with one another began in despair to conjugate. The results, how- ever, were nil ; the conjugates did not even recover from their forlorn hope. Other cases are related. . The result is evident. The process is essential for the species. The life runs in developmental cycles of multiplication by division, =- which are strictly limited. If conjugations with unrelated forms do not then occur the life ebbs. The sexual conjugation of the Ciliates is thus a rejuvinescence, as Biitschle and Engelmann main- tained. It is essential as a reorganization of the nucleus. After a ` prolonged series of divisions the nucleus undergoes senile degenera- tion. Without conjugation death would be inevitable. The death is a natural one, which some would deny. Sexual conjugation 18 the necessary condition of their “eternal youth and immortality.” GERMINAL Layers or Loiiao.—Mr. S. Watase has been studying the development of Loligo pealei. He finds that, owing to the immense amount of food yolk present, the gastrulation 18 masked, and that the mesoderm is formed before the endoderm 1s fully outlined. He traces the origin of the ink-bag and rectum from the proctodeal invagination, while the stomodeal inpushing gives rise to radula sac, salivary glands, and the digestive glands or “liver.” The endoderm is concerned only in forming a yolk membrane, and Mr. Watase thinks it wholly disappears, taking no part in the structure of the adult organs, the alimentary tract being formed solely of stomodeal and proctodeal invaginations. THE SPONGE SHRP, ALPHEUs.—Mr. F. H. Herrick con- tributes three articles on Alpheus to No. 63 of the John Hopkins Zoology. 257 University Circulars. He has studied five of the eight known West Indian forms, and finds that they vary considerably in habits ing almost impossible to separate the products of invagination into layers, or to separate others which wander from the ectoderm sions. _ He recognizes no less than twelve types, more than one of which may occur on a single fish. Most of these are small _ according as they are provided with (Opostomias micripnus, Echi- ores barbatum, Pachystomias microdon, Malacosteus indicus, stronesthes niger) or lack a pigmented mantle (Opostomias mieri- pnus). In no case are they provided with a reflector. The com- 258 General Notes. mias micripnus, Echiostoma barbatum, Pachystomias microdon, Astronesthes niger) are isolated and stand upright upon the surface, but are still more distinguished by the lack of a reflector. In others (Argyropelecus hemigymnus, Sternoptyx diaphana, Scopelus benoiti) the organ is provided with a shining reflector composed of needle-shaped or filiform elements. All of the foregoing are sunk in the skin, but in Xenodermichthys nodulosus occur simple organs which are provided with a pigmented mantle, and which project beyond the general surface and in some cases become stalked. In Halosaurus macrocheir and H. rostratus the organs are situated upon the scales of the lateral line and have a spindle shapé. The other main group of organs embrace irregular glands which may be scattered (Astronesthes niger), or be found on the under jaw (Argyropelecus hemigymnus, Sternoptyx diaphana); beneath the operculum (Halosawrus macrocheir); on the barbels and fin- rays (Opostomias micripnus, Malacosteus indicus); or may have a suborbital position, in the latter instance either having (Echios- toma barbatum, Pachystomias microdon, Malacosteus indicus, Scope- lus benoiti) or lacking a reflector (Opostomias micripnus, Astronesthes organs renders it probable that all are phosphorescent. Regarding the glandular organs the evidence is less direct, but judging from the analogy of other forms von Lendenfeld regards them as secreting a phosphorescent mucus. In both we have to deal with various modifications of the mucous canal system. Dr. von Lendenfeld states that the parietal organ of Sphenodon (Hatteria) has no homology with these organs, and that it is not, as has been sug- gested, a phosphorescent organ. EUTHERIA AND PrororHERtA.—In the AMERICAN NATURAL- ist for December, 1887 (vol. xxi., p. 1103), in a notice of “Thomas on Mammalian Dentition,” it is ‘‘ observed that the unnecessary terms Prototheria and Eutheria, which are generally ascribed to Professor Huxley in England, were really introduced by Professor Gill.” | Two quite different propositions were involved by the use of the terms used by Professor Huxley and myself. Professor Huxley Zoology. 259 simply substituted my names Prototheria for the Ornithodelphia or Monotremes, and Eutheria for the Monodelphia or Placentalia, introducing a new term—Metatheria—for the Didelphia or Mar- supialia. I perfectly concur with the belief that in these senses the terms are unnecessary. But far different was my use of the terms in question, and they were the expressions of a higher gene- ralization. Almost universally the placental. mammals had been contrasted with the non-placental. In my “Arrangement of the Families of Mammals” (1872), however, I combined (pp. 45, 46) the Placentals and Marsupials in one category (I.) with the Mono- tremes, in another (II.) fortifying the contrast by numerous ana- tomical characters; for these two sections I proposed the names EuTHERIA (I.) and Prororuerta (IL) in the table of “Contents” (pp. v., vi.) of the Arrangement. Subsequently, in “Johnson’s New Universal Cyclopedia” (vol. iii., 1877, p. 262), in the long article “Mammals,” I adopted the terms in connection with the definitions. It was then prevised that “the chief modifi- cations of the class of Mammals are expressed in three types whic have been differentiated as sub-classes, viz., Monodelphia, Didel- phia, and Ornithodelphia; these are themselves opposable under two categories, EUTHERIA and PROTOTHERIA.” Immediately fol- lowing, the groups so named were defined at length. | In the sense in which the terms Eutheria and Prototheria were used by myself I consider them to be necessary as the ver expressions of the generalizations formulated, but as used by Pro- fessor Huxley the names are simple synonyms of others long before in general use, and consequently “ unnecessary.” — Theodore Gill. THE MULTITUBERCULATA Monorremes.—It is announced in Nature (Feb. 16, 1888, p. 383) that Mr. E. B. Poulton has dis- covered teeth in sections of the jaws of a young Ornithorhynchus anatinus, made by Professor W. N. Parker. Three have been found in the upper jaw and two in the lower (the ramus imperfect), In the regions covered by the corneous bodies of the adult. The anterior tooth of the maxilla is “long, narrow and simple, as com- pared with the others.” The other teeth “were broad and large, those of the upper jaw containing two chief cusps in the inner side of the crown, and three or four small cusps on the outer side, while arrangement was reversed in the lower jaw.” 18 observation is of the highest importance. The description pen like that of the dentition of the Plagiaulacid genus Ptilodus. renders it extremely probable that the Multituberculata are Monotre- mata, and not Marsupialia, as has been supposed.—E. D. Cope. ZOOLOGICAL Nores.—Prorozoa.—Dr. D. S. Kellicott describes Q C figures five new species of American Infusoria in the Microsc dis p. 226). They are Podophrya inclinata, P. flexilis, Carchesium ulatum, and Opercularia humilis. 260 General Notes. Professor Ernst Haeckel has published an abridgement of his recent monograph of the “Challenger” Radiolaria. It appears under the title“ Grundriss einer allgemeine Naturgeschichte der Radiolarian,” in a quarto volume of 266 pages, illustrated with 64 of the plates of the ‘“‘ Challenger” Report. The price is sixty marks. EcCHINODERMS.— The brothers Sarasin call attention (Zool. Anz., x. 674) to the powers possessed by Linckia multifora of repairing injuriés, and figure a specimen where an arm has budded at its extremity a new star fish with four new rays, but state that the madreporic body is not yet developed. Worms.—Beddard calls attention (Zvol. Anz., No. 268) to the so-calied prostrate glands of earth-worms, claiming that these organs in Pericheeta an the homologue of the atrium in other earth-worms. He also describes the reproductive organs of Monilogaster, which differ from those of other worms and resemble those of the limico- lous forms. He shows that Claparéde’s division of the Oligochætes is unnatural. Mammats.—August Fjelstrup describes (Zool. Anz., No. 269) the histology of the skin of the black fish, Globiocephalus melas, and incidentally states that Eschricht’s statement that the number of hairs about the lower jaw and nasal openings and their arrangement . may be used in identifying foetal Cetacea is erroneous, th varying with size and development. . ENTOMOLOGY! Tue Grass-Eatine Turips.—Attention is called by Dr. Lint- ner in his annual report (reviewed below) to “An Unknown Grass- Pest.” As the insect in question is one which I have had under observation for many years, I am able to give more definite infor- mation regarding it than is contained in Dr. Lintner’s report. 40 fact, I feel a peculiar personal interest in the insect in question, as it was the first species upon which I made original observations ; and in a little work? published thirteen years ago I gave a bri account of it. : This grass-pest is exceedingly common and widespread.

The young insect pierces the stem in this place, where it is tender, and, sucking the juice from it, causes it to shrink and all parts above the injury to die. It appears first each season upon June grass, and frequently, a short time after this grass has headed out, the fields will be yellow with the dead heads of the grass. Later, the insect spreads to timothy and the other grasses ; but it never becomes as common upon these as upon Poa pratensis. The Species obtains its growth within the sheath of the upper blade, at the point indicated above. After it has acquired wings it crawls forth from this secure retreat, and can be swept from the grass in great numbers. As yet I have been unable to complete the life- history of the species by determining the manner in which it passes the winter and the mode of oviposition. Neither have I been able to suggest any practicable method of preventing the increase of the species. At one time I thought that the early mowing of the in- fested grass, causing the infested stalks to dry and become unfit food for the young Thrips, would accomplish this purpose, but, later, I found the insects in question feeding upon leaves of grass. In the work referred. to above the species was designated as Limothrips poaphagus MSS., but reference was made only to the habits of the insect. A description of the species has not yet been published.—J. H. Comstock. PROBABLE INCREASE IN ENTOMOLOGICAL INVESTIGATIONS.— Although the United States has taken a very prominent position as regards investigations in economic entomology, the work which the Department of Agriculture at Washington and the few State Ento- mologists have been able to do has not at all been commensurate with the demands of the subject. The life-history of a very large Proportion of the insects that are of economic importance remains unknown. And we are unable, as yet, in many cases where the transformations of the insect are known to suggest any practicable Means of preventing its ravages. The field for investigation has been altogether too large to be at all thoroughly worked by the small number of workers employed. There is now, however, a Prospect of a change. The establishment by Congress of an agri- cultural experiment station in each of the States in connection with the agricultural colleges will result in a considerable addition to the a oe investigators in economic entomology.

It is, however, 262 General Notes. briefer than would have been the case but for its having been unex- pectedly called for at an unusually early date, as explained in the letter of submittal. The more important entomological events of the year noted by also estimated that one-third of the onion crop was destroyed by the onion-fly, Phorbia ceparum. “ A new attack on wheat by a saw-fly larva” is described. | The larva in question crawls up the stalk, cuts it off about one inch below the head, and eats the soft green straw. One correspondent states that early in June the ground was thickly scattered with cut- off heads. An injury to strawberry plants, supposed to be caused by Bembidium quadrimaculatum, is discussed, but definite conclu- sions have not been reached. Serious injury to potato-leaves and to the foliage of carrots and parsnips by plant-lice in Massachusetts is noticed. There are many other short articles on well-known insects. The report is concluded by a list of publications and articles published by the entomologist in various journals during the year, together with an abstract of each. The list includes nearly fifty titles, and is evidence of great industry on the part of Dr. Lintner. Say’s Entromotoey.—Mr. Howard, in a paper before the Ento- _ mological Society of Washington, calls attention to a very genera misconception regarding the Leconte Edition of Say’s works. This edition does not include all of the entomological writings of that author, and it is evident that the editor simply intended to bring together the descriptive papers of Say. Grant Leprpoprerous Larva IN AusrraLia,— The larve of Chalepteryx collesi, a large moth which has been unusually abun- dant during the past summer in the vicinity of Sydney, often attains the length of seven inches and is robust in proportion. The larve of the beautiful swift, Zelotypia stacyi, measures eight inches when fully grown, and I have seen several Cossus larve of similar dimen- sions.” —A.

It includes a summary of the habits of the species and a discussion of some experiments in controlling this pest. EMBRYOLOGY. THE “ VENTRAL Suckers” or “Suckine Disks” OF THE TADPOLES OF DIFFERENT GENERA OF Froes AND Toaps.!— Thiele in this very interesting paper, shows that the singular sucker-like organs found behind the mouth and under side of the head in the tadpoles or larve of frogs and toads differ widely in form in different genera. They are clearly for the purpose of enabling the young larve to attach themselves to various fixed bodies in the water, such as weeds, the gelatinous egg-strings and masses from which they have been hatched, ete. They are thus afforded sup- port and prevented from sinking into the ooze to smother, and their enemies thus also doubtless find them a less ready prey. These disks are also shown by Thiele not to be of the nature of suctorial the sessile “suckers ”of larval toads and frogs. But the present writer cannot see how it is possible to homologize the sucking disk of larval gar pikes with the adhesive organs in larval Batrachians, use in the former the disk is in front of the mouth and in the latter it is usually quite behind the mouth, only in one case (Hyla) are the suckers found near the angle of the mouth, The larva of organ of the gar-pike’s larva and that of young toads and frogs, though it is probable that these organs in the latter are rai? £ Ftd Ha in pperat der Batrachierlarven, von Johannes Thiele.

Thiele further shows that inasmuch as these structures are gland- ular with no muscular apparatus, that the terms “sucker” or “sucking disk” are misnomers as applied to these —_ A better term might be proposed for these structures in young ta d- poles, and i writer would suggest that they be called pide adhesive org The nih of these organs differ widely in different genera of Salientia and will afford a valuable means of identifying the larve. In Discoglossus pictus, the adhesive organ behind the mouth is hemi- spherical, with a V-shaped groove on its surface, the V opening forward. In Pelobates fuscus the adhesive organ is Y-shaped with a Y-shaped groove on its surface and the limbs of the whole organ extending forward to embrace the angles of the mouth. In Bufo vulgaris the organ is V-shaped, with a V-shaped .groove, and the limbs of the V come into contact with the angles of the mouth. In Bufo viridis the organ is cresent-shaped, not in contact with the mouth, but a little behind it, as in Discoglossus, and with a widely open V-shaped groove. In Rana esculenta and R. fusca there are two distinct oval adhesive organs on either side of the median line with traces of a V-shaped groove connecting them, and both are behind the mouth. In Rana agilis there are two separate ad- hesive organs, one on each side behind the mouth, and each has a slight depression on its posterior border. In ’ Hyla arborea there are two circular adhesive organs close to the angles of the — mouth at either side. In Bombinator igneus there are two oval ad- hesive organs behind the mouth, whicn are in close contact, an later on fuse into a single organ, both having an oval depression in the centre—J. A. R. PSYCHOLOGY. THE Copr-MontcomEery Discusston.— The Theism of Evolu- tion. «The following is offered as a synopsis of the leading opinions maintained by the writer in a series of articles furnished by him to The Open Court during 1887, in reply.to articles written by Dr. Edmund Bee LE: I. PRINCIPIA. 1. In the universe there exist both mind and matter, subject and D. The evidence for the existence of mind is found in ern ness ; first, of ourselves, and, second, of other living beings, w ; motions, identical with those which we make under the influence y our own consciousness, convince us of their possession of it. Psychology. 265 3. The evidence for the existence of matter is found in certain modifications experienc y our consciousness, especially in the ‘sensations of extension and resistance. . Since consciousness does not exist apart from the motion of matter, we regard it as a property of the matter in motion, that is, as a property of energy. II, FACTA. 1. The gross activity of consciousness is immediately conditioned by matter. 2. In certain of its thought-forms consciousness is not imme- diately conditioned by matter, but only by its past experience of matter. _3. The forms of consciousness mentioned under (2) control the direction of energy, and hence the use of matter. _ 4. The proof of (3) is seen in the designed movements of animals in which they direct a current of energy in order to produce a result more or less exactly adapted to satisfy the conditions “demanded by a sensation. 5. As soon as a designed movement has been fully acquired, that is, so soon as the animal mechanism necessary for its produc- tion has been created, it is performed without consciousness of effort, and may be performed unconsciously, or even in a state of general unconsciousness, Therefore designed automatic acts originated in - consciousness, 6. Evolution of organic types is the resultant of the interaction of subject and object, or the living organism and its environment. 7. The function of the organism in evolution is to produce vari- -ations in its structure as an effect of its motions. 8. The function of the environment in evolution is to impress or destroy the organism, or to restrain, permit or encourage its use; that is, to exercise natural selection. ) 9. The effect of this interaction, where the movements of the “Organism are stimulated, is to produce specialized structures and t out of generalized ones. Where the action of the organism 18 not stimulated, the result is to produce degenerate types. _ 40, It follows that organic evolution is the result, mediate or immediate, of consciousness ; that is, of the interaction of conscious. nergy or its residua, the organic vital energies, in interaction with the environment. I. Organic energies perform chemical syntheses and analyses, ‘demonstrating the control of vital over chemical energy. : , 12. Whereas physical and chemical energies result only in dissipation of energy and integration of matter, the energy otis tion produces complication of matter for the profitable ““irection and storage of energy. : 266 General Notes. NOTE. The only comment which I have to make on Dr. Montgomery’s _ argument is this: that, while denying that conspicuousness can con- trol energy (matter), he admits that matter controls consciousness. ese two positions are logically inconsistent. the affirmative is true of consciousness it is true of matter, and vice versa. On other points I can agree fully with Dr. Montgomery.—E. D. Cope. III. CONCLUSIONES. 1. The function of control and construction displayed by the energy of evolution (bathmism) leads us to infer that this type of energy can control its conditions sufficiently to enable it to have a wide distribution in space and time in the universe. Since the originating and controlling element of this special type of energy is consciousness, it is inferred that consciousness has existed prior to any given special inorganic type of energy. . As the condition of consciousness is the unspecialized or uncreated condition of energy, it is inferred that consciousness is a property of matter in an unspecialized or generalized condition in some respect. 4, Since protoplasm is not in all respects the most generalized conceivable condition of matter, it is inferred that there are physi- cal bases of consciousness other than protoplasm. ; 5. It is inferred from the preceding considerations that the exist- ence of primitive consciousness in primitive forms of matter is not only possible but probable, and this consciousness constitutes primitive person or Deity.—E. D. Cope. : Summary of the Controversy between Professor Cope and Myself. —Professor Cope maintains that mind is the active agent in the - organization of living beings. I maintain, on the contrary, that the mind of living beings is itself only a product or outcome of their organization. eee Professor Cope’s view leads him to assume as original building- material an entirely “ unspecialized” kind of matter, and as builder or organizer a supreme mind or Deity inherent in such matter. In this connection I had to point out the great dilemma of modern philosophy ; the impossibility, namely, of conceiving any- thing mental imparting motion or direction to anything material. Leading thinkers, of almost every school, when seriously contem- plating the apparent occurrence of an intercommunication between mind and matter, have declared it scientifically impossible and phi- losophically inconceivable. Yet, Professor Cope’s entire theory of organization through mental agency rests on the flat assertion of its being a self-evident proposition, that our mind moves our body. I further pointed out that to escape from this distracting dilemma of having on the one side a mind incapable of naturally acting upon matter, and on the other side matter incapable of naturally - Psychology. 267 acting upon mind—that to escape this dead-lock in the way of a unitary or monistic conception of nature, a theory of cognition is indispensable. y help of such a theory we become irrefragably aware that matter and motion are only perceptual signs within our own con- sciousness of the presence of a non-mental existent and its activity, which are stimulating our senses in specific ways. We can be cer- tain that what thus effects our senses. is really non-mental in its nature; for nothing mental has power to affect our senses and to awaken specific percepts in us. This non-mental existent and its activity cannot possibly, in the remotest degree, resemble their per- ceptual representation in us; for how can anything non-menta resemble anything mental? Therefore, they are not in themselves what we perceptually know as matter and motion. And thus the conception of mind moving matter becomes at once irrelevant. The dualistic opposition of matter and mind is seen to be superficial, and only due to inadequte conception on our part. These truths, yielded by the theory of cognition, I have used to explain our voluntary movements, upon which movements the — question of the influence of our “ mind ” on our body actually centers. _ Our veritable being has power so to affect the sensibility of an observer as to arouse its perceptual representation in him. This tr arm of the observer, in all its details, forms clearly part of 18 Own consciousness; but it representatively corresponds to the characteristics of the non-mental existent, which is stimulating his sen ses, Now, it is evidently the transient activity or function of that part of the permanent living being which we perceive as his nerve-system that yields to him all his conscious states. While this functional play of inner awareness is taking place in the observed organism, the observer himself perceives nothing but motion; motion of molecules in the nerve-system, and dependent movements of peripheral parts of the organism, such as features and limbs. “Mind” or consciousness is thus a functional outcome of the organization of living beings, and its development is found to keep strict pace with the progressive organization of living forms.— Edmund Montgomery.— From Open Court, Chicago, March 1, 1888. Tue Rep Fox ar Scnoor.—Nearing Ashland, Wisconsin, one May day, an Indian lad boarded the train with a basket, in which were three little red foxes (Vulpes rufus), their eyes just open, a ome as little fairies. He expected a bounty for their scalps, actly sold one little fellow to me. Too young to know what a ed was,—only as an inherited instinct, I determined to see how T he would yield to kind treatment and general domestication. 268 General Notes. Returning to my Illinois home, he was fastened by a light chain about fifteen feet long to a pine tree near the back door. Two small dry-goods boxes, placed one above the other, with a door in the same end of each, served as a two-story kennel, the doors facing the house affording ample opportunity for observation. Too young to eat readily, we taught him to drink milk, and gradually to take tender meat, his teeth being at this time only tiny points, weaker— relatively, than a puppy’s of similar age. He grew rapidly, and when feeding we held him in our laps, fondling him as a kitten, allowing him to lap and chew our fingers freely. Our shoulder came to be a favorite seat, and until too large, he liked a step still higher ; later, to put his fore feet up, then repeatedly to jump from our shoulders to the ground, as we sat upon the grass. He was equally at home in the house where he was given ‘entire liberty. It was now time that he and the cat, with her two kits, should eat and drink together and from the same dish. Kitty, accustomed to having various animals introduced into her hdéme for observation studies, quietly accepted the inevitable. | While drinking milk, of which there was always plenty, no jealousy for individual rights appeared, but as the fox grew faster than the kits, and the plate of meat sometimes seemed meager for four, he would eat as fast as possible, snuff a little, as much as to say, “go away,”—give another snuff, and not being heeded, would gently pick up one of the kittens by the nape of its neck, and carrying it off a little ways, set it down, then rush back to the dish, to find the kit there also. This being repeated two or three times, with no satisfactory results, as if out of patience, he would grow more decided an inclined to hurt them a little, making them ery, but they were never conquered. When he had had enough, and a little comparatively meats upon his disposition and found him, after a few days on raw diet, inclined to lap heavier, and chew our fingers harder, but we never feared being bitten. ; He greatly enjoyed playing with the kittens but they, being 0 — much smaller and weaker, would tire more quickly and start off to play by themselves. An artifice was at hand to coax them back. Going nearly to the end of his chain, and facing the inside of the circle, though with a keen eye to the outside, he would quietly wag his tail back and forth in the grass. This motion was too great @ Psychology. 269 temptation for the kits who would chase it, when quick as a flash, he would turn and grasp one, without hurting it but with such a look of pleasure and conquest. This feat would be accomplished frequently till all preferred rest or another pastime. n apple tree stood near the pine, and the young fruit fell freely. With these apples the fox would amuse himself by the hour, play- ing ball, tossing them and running after them, or tossing them up and catching them in his mouth, also chasing the leaves as they fell to the ground, but he never inclined to gather any materials to make a nest, nor to eat the sour apples. For persons, he manifested great preferences, and the children who came daily to play with him were no exception. From some, he would take almost anything, especially enjoying a play with their hair as they lay in the grass with him, or to lick their faces and feet, from others he required due reserve, though he never attempted to bite, but often snuffed at them, and held his mouth slightly open, as a cat will, when some disagreeable odor is perceived. When a stranger appeared he was manifestly “foxy,” running away as far as he could, and was not readily coaxed by dainty morsels, until some friend came, by whose manner he was assured.. My aged grandfather was always kind to him, though in heart he - accused him of possible treachery. Did the fox detect this, or why did he in turn always manifest a marked distrust inhim?

In summer he often lay in this hollow, but his favorite sleeping place, even in mid-winter was on top of the highest box, the wind playing generally in his long, thick and fine hair. Was this position and his love for sitting on our shoulders or any elevated place a remnant of some arboreal strain? At twilight and by moonlight was his play time, turning summersaults, rolling over and over, jumping from the second story to the first and then to the ground and back, or entirely over his kennel, etc., etc., but though always on the alert, we never noticed anything which indicated discontent or fear, only as strangers came near him.

Stafford, of Chicago, owns an English Bull Terrier about two years old. “Shave” 1s indulged considerably by his master, and occasionally allowed to remain indoors if the weather is bad. : Once Shave had a severe cold and coughed considerably, during which time he was allowed to stay in the house. Since his recovery when any mention is made of turning him out of doors he-coughs vigorously, and wheezes, in fair imitation of asthma. The trick does not avail him now, however, but he recollects that it did once. When put out he drops the pretence at once dashes gaily off after neighborhood company. Shave’s mother, it is said, used to ring an electric bell by press- ing upon the button in the floor when she wanted to go out. There is a chance for this to be accidental, but the family believe that it is intentionally done.

THE LATE DISCOVERIES oF Mr. FRANK CUSHING IN ARI- ZONA.— Mr. Frank Cushing is well known to the people of the United States for his discoveries and studies among the Zuni Indians. He has added another chaplet to his wreath of fame by the discovery of two other Indian cities, believed by him to have been the habita- tion of the ancestors of the Zuñis. Mr. Cushing joined the tribe of Zuñis, was adopted by. them, and finally was initiated into the order of their priesthood. His escort of a band of Zuñi chiefs and high priests to the States to show to them the Atlantic ocean, the sea of the sunrise, containing the water of life, is well known. His knowledge and information obtained through these long years of intercourse has equipped him for further study and search, and has enabled him to secure success where other men merely book- learned would have failed. He is fairly entitled to the credit of his last achievement. he had discovered a city three miles long and at some places one mile in width. This city was somewhat irregularly laid out, con- by a eerncipally of large squares or blocks of houses surrounded by a high wall, apparently for protection. The cause of the ruined condition of the city and its desertion by the inhabitants was deter- sgt e been an earthquake. The adobé walls were shaken at their foundation, and fell outwards. The roof had fallen to the Ser crushing everything which had been in the house, in one case the cooking vessel as it sat upon the fire. This evident sud- on, Wat ithsonian Institu- tion, Washington h is edited by Thomas Wilson, Smi : 272 General Notes. denness of the catastrophe was a factor in forming the belief that there had been an earthquake. The implements of the household and articles in every-day use have been found in many places, and saved. Their examination will afford opportunities for studying the every-day life, and writing the history of these prehistoric people. Many bodies have been found crushed in the débris of the fallen roofs and walls. Many interments have also been dis- covered. Some were by inhumation, and these were believed to be priests. And herein comes the value of Mr. Cushing’s knowledge as a Zuñi priest. These burials were usually made within the houses themselves. The grave was dug in the earth forming the floor, the body placed therein together with the usual articles, receptacles for food, pottery, etc., and being filled up, the floor would soon take its original hardness. The objects thus found interred formed the principal evidence of the priestly character of these dead. The pottery was decorated similar to the modern Zuñi pottery. The same symbols were to be seen thereon. The line of life always open at its extremities was continually present. An referring again to the Zuñi religion, the pottery was left unbroken. Other cemeteries or graves were found outside the walls. These were of common people, had no traces of priestly character, were frequently by incineration as inhumation, and the vessels accom- panying them were always broken. No object in metal was found. as has the first, but he finds extensive works for irrigation. Ditches have been cut connecting it with the Salt River, some miles dis- tant, for the conduct of water. For this reason he has named it Las Acequias. © Dr. Washington Matthews, Surg. U. S. A., of the Army Medi- cal Museum, visited Mr. Cushing at the scene of his discoveries during the past fall. He found him much broken in health, sadly in need. of rest. Dr. Matthews prescribed for him, relieved him from his duties, and took him to San Diego, to recuperate. , The number of skeletons could scarcely be estimated, but their state of preservation was fairly good, yet requiring care and scien- tific handling in order to secure them, The finds in this direction have been sufficiently large in number and importance to fe the Museum in sending one of its assistants, Dr. Wortman, arged with the necessary material, who will devote himself to the care and preservation of the skeletons as they are unearthed.

THE CELTIC Socrery or MONTREAL has recently published an octavo volume of 231 pages, containing some of the papers read before the society during the years 1884 to 1887; to judge from their names, the office-bearers, and perhaps the other members also, are all of Scotch descent. The publisher of the volume, called “Transactions of the Celtic Society, ” is Mr. William Drysdale, and among the “ office-holders ” we find also a bard, Mr. Archibald Mackillop. The constitution states that the object of the Society shall be the promotion of the study of the “Celtic Language and Literature.” The society was organized in December, 1883, and now counts 250 members, many prominent Canadian statesmen that this revolt occurred anno 178 before Christ.

Pitt-Rivers, of the British Army, is known to archeology as well under his former name, Col. Lane-Fox, as under his present name. Upon the decease of an elder brother, he took, as the next heir, the entailed family estates, and by provision of the entail was required to change his name as above. e family estate was at Cranborne Chase, not far from Salisbury. Here Gen. Pitt-Rivers had ample scope to indulge his archzologic tastes in excavations. He has profited by the occasion, and has lately published for private distribution a magnificent quarto- volume, entitled “ Excavations in Cranborne Chase, near Rush- more, on the Borders of Dorset and Wiltshire.” He has contin- ued his investigations, and read before the Anthropological Institute at London an article in continuation thereof. His article is fol- lowed by one of Dr. Beddoe’s, which pursues the same line 0 thought. Both are largely devoted to a calculation of the stature of the prehistoric races, as estimated from the long bones of the skeletons found in the tombs. The rules adopted by the different authorities eare commented upon in the light of experience by these two gntlemen. They belong to the science of anthropometry, and it would increase the length of this article beyond proper limits to give them, The importance of anthropometry is better recognized in Europe than it has been in the United States, which is much to our detriment. Gen. Rivers says: “I draw the attention of anthropologists to the important point than questions of stature enter so largely into all racial speculations that a uniform system of estimating stature from the long bones is a matter of most ungent necessity.” n, “I have conformed to Dr. Topinard’s rules for the sake of uniformity, and in this I am supported by Dr. Garson. _ (10026) Bane: (758) 4 DISTRICT OF COLUMBIA.

The Smithsonian Institution has issued the following Circular (No. 36) concerning the Department of Antiquities :— The Smithsonian Institution desires answers to the following questions concerning that class of American Aboriginal Stone Relics which have been heretofore denominated “rude or unfinished implements of the paleolithic type.” These implements are described by Dr. C.

Garman, of Champaign, Ill., finds tablets made of plaster preferable to most others for mounting anatomical prepara- tions. e following communication on this subject has been received from Mr. Garman :— “ My experiments with this material were made without knowl- edge of its use for the purpose in other quarters, and I was sur- prised to learn, upon inquiry, that the large white tablets used for ordinary alcoholic specimens in the Museum of Comparative Zool- ogy were of plaster, and had been cast upon glass. However, I believe the manner of making them, and the facility with which they can be produced, is not as generally known as it should be, and that, as my results were reached independently, the details of the method here given may prove of service even to those who are accustomed to the use of plaster. I do not know that colored uncolored plaster, satisfies most needs in the way of backgrounds. Black ink and carmine staining fluids can be Pte | to stain the white tablets. But the latter color is not often a desirable one, and if it is to be used can be more economically applied by first dissolving carmine in water with heat, then adding the plaster, finally casting 1 Edited by C.

A variety of colors may be obtained by using the ‘ Flor- entine Fresco Colors’ sold by F. W. Devoe & Co., New York. They may be mixed with the plaster. The chrome orange, chrome yellow, Venetian red and ivory black have been on trial in tablets for about a week, and show no change under the alcohol. “The use of plaster in tablets is not claimed to be new with the writer, but this method of manipulation and coloring is the result of independent experiment, and may therefore present some fea- tures of interest. Tablets as above prepared have proved, in my experience, superior to those made of wax in the matter of cost, in the facility with which they are to be prepared, and in neatness of appearance.” PREPARATION OF THE Eaes OF ASCARIS MEGALOCEPHALA.— Through the researches of M. Nussbaum,! Ed. van Beneden,? J. B. arnoy,’ and Otto Zacharias,‘ the egg of Ascaris megalocephala of the horse has become a classical object for the study of fecundation. In the simple structure and enormous size of its nuclei, this egg offers unequalled advantages for such study. But a very serious drawback is found in the thick impervious egg-membrane, which is capable of resisting for a long time the action of preservative reagents. Dilute acetic or nitric acid requires at least from eight to ten days to penetrate; and alcohol of 40 to 50 per cent., two or three months. Development goes on undisturbed in osmic acid of per cent.; and several days are necessary even for absolute alco- hol to take effect. For tracing the karyokinetic phenomena of fecundation, it is of the utmost importance to find reagents that will kill and fix quickly, as reliable preparations of transitory stages in nuclear metamor- . Phosis cannot be expected with reagents that penetrate slowly, o Zacharias *® has discovered an acid mixture which overcomes the resitence of the egg-membrane, and fixes the egg completely Within 25 to 30 minutes. The mixture consists of Alcohol (90 to 100 per cent.) 80 cem. Glacial acetic acid 20 cem. Osmic acid (1 per cent.) 20 to 30 drops. A little glycerine or chloroform increases the clarifying power of the mixture, a Archiv f. mik. Anat,, xxiii., 1884. : Archives de Biol., iv., 1884. : 1e top ape 1886-7, reniv f. mik.

Van Beneden (Nouvelles Recherches sur la fécondation, ete., 1887) has employed a stronger mixture, consisting of absolute alcohol and acetic acid in equal parts, without the addition of osmic acid. Preparation of Material—1. Freshly obtained! Ascaris females are placed between two sheets of cotton, which have been moistened a little in a 3 per cent. solution of common salt, then covered with a bell glass, and exposed one to three hours to an incubation tem- perature of 25°C. This procedure brings the polar globules to development in the younger eggs, and forces the cleavage in the older eggs. 2. After an hour’s incubation, it is well to preserve a part of the material at disposal. The genital sacks are laid bare by a longitu- dinal slit in the body-wall, opposite the sexual aperture; the vagina is then cut free from the body, the alimentary tract lying between the two sacks is carefully removed, and the ovarian portions of the sacks are cut off, leaving the uterine portions with their contents for preservation. The anterior ends of the uteri contain eggs in all stages of maturation and fecundation ; the posterior ends contain eggs already beginning to cleave. The killing and hardening pro- cess should vary considerably for these different stages. 3. It is advisable, therefore, to cut each uterus into thirds, and to expose the anterior third to the action of the acid mixture only five to seven minutes, the middle third ten to fifteen minutes, and the posterior third at least twenty-five minutes. After fixation, the anterior and middle thirds are transferred to 30 per cent. alcohol, and after a few hours to 50 per cent. alcohol, in which they may be kept for a long time. Eggs in process of cleavage—found in the posterior third—should be removed to absolute alcohol the moment they begin to show a light brown staining. After two to three hours they are to be transferred to 70 per cent. alcohol for preser- vation. If the acid mixture be heated to about 24°C., the poste- rior third of the uterus will require an exposure of only ten to fif- teen minutes. : 4. Schneider’s acid carmine is an excellent staining agent. It 1s prepared as follows: Glacial acetic acid is diluted with distilled water to about 50 per cent.; then as much pulverized carmine 1s added to the boiling acid as will dissolve. - After filtering until the fluid becomes clear, a little rectified wood-vinegar is added (one drop A. pyrolignosum to ten ccm. of the carmine solution) for the purpose of strengthening the clarifying power of the mixture. he younger stages may be left in the dye three to four hours, the older stages eight to ten hours. Beautiful views of the karyokinetic figures are thus obtained, but they are not permanent. After three to four hours they begin to lose in distinctness. 1 From the living horse, by means of arsenic pills.

Tryon, Jr. , the Conchologist, died in Philadelphia February 6th, aged fifty years. Although not a Friend, his ucation was gained at Friends’ school, and at an early age he engaged in business with his father and brother. The lack of collegiate education he amply made up in later life by private study. His early years were devoted assiduously to his business and to his studies, and his attention having been concentrated on natural history, and especially on the study of shells, he withdrew in 1867 from business in order to devote himself solely to his favorite pursuit. A man of untiring energy and perseverance, he 500 me eminent in this domain of science. His first paper was published in the proceedings of the Academy of Natural Sciences for 1861, under the title “On the Mollusca of Harpers — Ferry, Virginia.” In 1865 he established the“ American Journal of Conchology,” of which seven annual volumes were issued. To this, and to the proceedings of the Academy he contributed numer- ous papers, numbering at the end of 1873 no less than sixty-four contributions to this favorite science, all showing characteristic accuracy of detail and patient research. In addition to these ag et he also issued a Bibliography of American Writers on Conchology - z 1861 ; a Monograph of the Fresh Water Univalve Mollusca of the United States, in continuation of Haldeman’s work on the same subject; a Synonymy of the Species of Strepomatidæ in 1865; a Monograph of the Terrestrial Mollusca inhabiting the United States, 1866 ; an American Marine Conchology, 1873 ; the third Volume of the Land and Fresh Water Shells of the United States, © published by the Smithsonian Institution, and a Structural and — 280 General Notes.

The latter is a magnificent work, profusely illustrated, but was only preliminary to the crowning work of his life, which, unhappily, he has been unable to finish. This was his Manual of Conchology, Structural and Systematic, of which the first volume appeared in 1879, and of which nine volumes of the first series, on marine shells, and three of the second, on land shells, have been issued. It is no exaggeration to say that this is the most extensive system- atic work on any branch of natural science which has yet appeared in the United States. The collection of shells of the Philadel- phia Academy of Natural Sciences was largely his gift to the insti- tution, and it was one of the largest in the world.

Y., No- vember 18, 1810. Died in Cambridge, Mass., January 30, 1888. When a great man dies, it is fitting that his survivors should re- count his deeds, and learn the lessons which his life and labors teach. Born in the poverty and obscurity of a backwoods village, far from any of the great centres of learning, there was nothing 0 promise in the future for the little tanner boy of the Mohawk Val- ley. When he urged the unwilling horse on his tiresome round, and wearily labored at his monotonous task of feeding the bark-mill, who could have foretold his after greatness? What prophet could have seen in the village school-boy, so far removed from all incentives to the study of science, the future leader of one of the great branches of science in America ? Denied the advantages of a collegiate education, he completed, at the age of twenty, the study of medicine in the Fairfield College of Physicians and Surgeons for the Western District of New York, and doubtless the scientific studies of the course had much to do with making him what in his after life he always was, em- phatically a scientific man. His botanical work began during his study of medicine, and by the time of his graduation he had already done something in the way of collecting and identifying the plants of his locality. ; The great event of the young botanist’s life was his meeting, when twenty-one years of age, with Dr: John Torrey, then teach- ing in New York City. Under the inspiration of Torrey, his studies were led into those lines of work in which his life was des- tined to be spent. In his herbarium and by his help Gray’s first botanical contribution (viz.: “North American Graminee and : Scientific News. 281 Cyperaceæ ”) was wrought out. In the introductory note to part I, which bears date of February 1, 1834, acknowledgment is made of the author’s obligations to Torrey “ for the interest he has taken in his botanical pursuits, for the important aid he has rendered him in the determination of doubtful species, and for the use of his valuable library and herbarium.” In his twenty-ninth year Dr. Gray visited Europe, and made the acquaintance of many of the great botanists of that time,— the elder and the younger Hooker, Bentham, Greville, Robert Brown, Lindley, Mirbel, Decaisne, St. Hilaire, Boissier, Adrien de Jussieu, Endlicher, Von Martius, the De Candolles, Schlechten- dal, Kunth, Ehrenberg and many others. ree years later he was called to the chair in Harvard Col- lege, which he filled for thirty-one years, until relieved of the drudgery of teaching in 1873. When sixty years old he was elected president of the American Association for the Advance- ment of Science, at the meeting held in Troy, and two years later delivered his famous address, “Sequoia and its History,” at Dubuque. Upon the anniversary of his seventy-fifth birthday the botanists of the country united in a testimonial of respect and veneration to the one on all hands acknowledged to be their leader. Last year, on his — revisiting England and Scotland, the Universities of Oxford, Cam- ridge and Edinburgh, honored themselves as well as him by con- ferring upon him their highest degrees. „The activity of his mind throughout a long life may be in- , dicated by the following list of the more important of his pub- lications, with the age at which they were issued: At 24.—North American Graminex and Cyperacee.

Injustice to no one was intended, nor was there any personal feeling in the matter. My sole desire was to make it known, as no one else could, that a very large portion of Mr. Harger’s scientific labors for the past seventeen years has been quite unknown to the scientific world. This is conceded by those most interested in the matter, and any details as to the precise part of the work that he committed to paper is immaterial. Professor Marsh insists that a portion of the descriptive matter of the Dinocerata was written by himself, and presents evidence which I will admit sustains his assertion. The chapters on the brain and skull I have in my notice of Mr. Harger conceded to him without in any way affecting the general fact. He must and will admit that a considerable part of the work was pre- pared by Mr. Harger without his name appearing anywhere as its author. I have nothing to say as to whether such a course was right or wrong. Others, with Professor Marsh, may claim that an author has a right to hire and pay for scientific work, without its being any one else’s affair. I do say, however, without fear of denial, that much of the valuable scientific work published by Pro- fessor Marsh has been due to the conscientious accuracy, soun judgment, and general scientific scholarship of Mr. Harger. The bibliography was almost wholly prepared by myself, but was 5° modified that I should be loth to have its authorship imputed to me.—S. W.

It is hoped—first, to secure a location at Woods Holl, Mass., where the fauna and flora are abundant and varied; second, to build a, laboratory with two stories—the lower story to have accommodations for teaching at least twenty-five per- sons, the upper story to have work-places for investigators—to fur- nish aquaria, microscopes, microtomes, glassware, etc., also a con- stant supply of water for aquaria ; third, to have a convenient land- ing, boats, collecting apparatus, ete. To meet the running expenses, fees will be charged those who work at the laboratory.

Sedgwick read a paper entitled “ A Biological Examination of the Water Supply of Newton, Massachusetts,” it being a record of joint work done on the subject by the speaker and Mr. S. R. Bartlett. ference was found to exist between the river and basin water. Water from the river gave as an average 261 colonies of Bacteria in a cubic centimetre ; that from the basin, 42; from the reservoir, when the water is pumped, 23; and that taken from the tap in Newton, only 6. The following results bear out the opinion that Newton’s water supply is superior. Newton water was thus found to contain 6 micro-organisms in a cubic centimetre; Spot pond, Malden, 10; Cochitnate, 43; Mystic, 204; Croton, N. Y., from 54 to 256. The chemical tests also justified the reputation of the Newton water for purity. The next paper, also read by Prof. Sedgwick, explained a “ New Method for the Biological Examination of Air,” by Prof. Sedgwick and Mr. G. R. Tucker. A description of the previous methods used for this purpose was first given. In the new method the air is drawn through a small tube containing granulated sugar, the Sugar being then mixed in an enlargement of the same tube, with a proper amount of gelatine to insure the growth of any germs held by it. The apparatus for drawing always the same amount of air through the tube is an ingenious one, and is the invention of Mr. Tucker. It has been found by numerous experiments that the Sugar catches all the Bacteria of the air. The apparatus is simple in construction and working, and is designed to be used in hospital wards and at any place where frequent examinations of the air are desired. It was shown in working order, and a large number of plates and tubes showing micro-organisms in various stages of de- velopment were exhibited.

Putnam 288 General Notes. spoke of the serpent-mound in Adams county, Ohio, which has recently come into possession of the Peabody Museum of American Archeology and Ethnology, at Cambridge, Mass. This mound was first brought to general knowledge by Messrs. Squire and Davis in 1849, previous to which time it had only a local reputation. It was then covered with forests, and has since been ploughed over a number of times and devoted to crops. The mound is lowest at the tail and increases in height toward the head, and varies from four .to nine feet; in width it varies from eleven to twenty-one feet, and its length is about fifteen hundred feet. The serpent makes four or five convolutions, running north and south, and the tail ends in a triple coil. In front of the mouth is an oval mound, as though the serpent were about to swallow an egg—as the lecturer expressed it. On each side of the neck are two other mounds—one natural, grow- ing out of the decay of an enormous oak tree, and the other arti- - ficial. Near the tail is another mound, built up from the white clay bottom, over which is a heavy layer of stones—not the lime- stone of the surface, but a sandstone brought from a creek a quarter of a mile away. In this mound, at a depth of from two to five feet, occur a considerable number of intrusive burials ; but in the centre, lying at length on four inches of wood-ashes, was found the skele- ton of a chief six feet in height, with a brain capacity greater than that of Daniel Webster. The speaker believed the mound to have been built in honor of this chief. The skeleton is in good condition, and is now preserved in the Museum at Cambridge. No weapon was found in the mound and no ornament, except one fresh-water clam-shell. AA w THE AMERICAN NATURALIST. < Vou. XXII. APRIL, 1888. No. 256, SIX WEEKS IN SOUTHERN MINDANAO. BY J. B. STEERE. A THREE days’ voyage from Puer to Princesa, in the island of Paraqua, by way of Balabac and Sooloo, brought us to the port of Zamboanga, in the southwest part of Mindanao. The harbor is of but little value. It is partly sheltered on the south by the low island of Santa Cruz opposite, but is open to the storms from the southeast. There had been a heavy blow from this direction before we arrived, and a high sea was running ; but toward night we got our baggage into a huge dug-out, and were paddled ashore. After some trouble with the customs’ offi- cers over our baggage, we were finally, after dark, domiciled in a shaky old fonda, the only hotel the place affords, a liquor and tobacco shop and place for the sale of postage stamps and lottery tickets below, and a lodging place above. We gota promising view the next morning from our window intoa yard below, where a dozen pairs of immense bivalve shells (Tridacna gigas) lay in the sun. A careful measurement of the largest pair showed three feet and five inches in length and two feet and five inches across the valves. They must have weighed toward two hundred pounds each, or four hundred pounds for a single shell. We found a single valve made a good load for two men.

Acad., 1879, p. 14. ings Amer. Philosoph. Soc. 1886, p. 526. 316 Observations on Amphiuma. This assumption has been made in the case of Amphiuma. On general principles, Cuvier concluded that in early life it has gills. This was uncertain, and has been denied. Later authorities, among them Professor Huxley, state that its gills are “caducous,” but that this conclusion rests on any one’s observations T am not aware. Of its other habits little seems to be known. Holbrook, in his great work on North American Reptiles, thus speaks of the species :— “Amphiuma means lives in muddy water or in mud. Harlan says they have been found at Pensacola three feet or more deep in mud of the consistency of mortar, in which they burrow like earth- worms. They inhabit the ditches of our rice-fields, and feed on small fish and various fresh-water shells, as Unio, etc.; beetles and other insects have also been found in their stomachs. Sometimes, like eels, they are found on dry land, but for what purpose they approach it is unknown” (N. A. Herp., 1842, v., 91). “T am unacquainted with the habits of the Amphiuma tridacty- lum, but suppose these to he similar to those of the Amphiuma means” (Ibid., 93). At the close of August, 1887, I spent a few days in Little Rock, Ark., in the employ of Dr. Branner, of the Arkansas Geological Survey. On September 1st I visited a cypress swamp in the vicin- ity of the city for the purpose of collecting some reptiles. During the severe summer drought this swamp had been almost completely dried up, and there was little chance to get anything except by turning over pieces of fallen timber. Beneath a log of consider- able size I found, to my surprise, a large animal coiled up, which by its smooth glistening skin I immediately saw could not be a snake ; but, having never before seen a living Amphiuma, it took me some time to realize that I had before me one of these animals. After making due preparations to prevent its escape, I gave the animal a push with a stout stick, and then, no attempt at retreat being made, I lifted it out of the slight depression in which it was — lying and let it straighten itself out. Meanwhile I had observed, lying in the midst of the coils, a mass of moist-looking matter, nearly as large as one’s fist. Picking this up, I discovered it to be a mass of eggs. This was put into a jar of alcohol, and imme- diately the young within the egg could be seen writhing about, thus showing that they were in an advanced stage of development. The mother offered no resistance on being handled, and was put into 4 Observations on Amphiuma. 317 small school satchel and carried to the State Geologist’s office, a mile away, with two empty fruit jars lying on her. That night she was kept in an empty boot-box. This was some eighteen inches in height, and from it she made efforts to escape. She would erect herself in one corner until her head was on a level with the edge of the box, but she could get no further. Once in falling down she uttered a shrill sound somewhat like a whistle or the peeping of a young chicken. A cry like that of a young duck has been attrib- uted by some observer to the Siren, but Barton in some of his writ- ings denies the statement that such a sound is made. The limbs of these animals are very small. For instance, of this one, having a length of thirty-one inches, the hinder limbs are only three-fourths of an inch long, the anterior only one-half an inch. Yet, when it was moving over the ground or the floor, it was amusing to observe that its feet were put forward and drawn back, as if they really could be of some use. On irritating this Amphiume by pushing her with a stick she would snap at it viciously, and on further irritation would seize it in her jaws and, springing from the floor in the form of a spiral, would turn rapidly round and round, thus twisting the stick in one’s hand. Any enemy thus attacked would certainly find his interest in the affair fully aroused. There are two points in the structure of the adult to which I wish to call attention; although no doubt they have already been observed by anatomists. The first is that there isa little lobe of skin forming the anterior boundary of the gill-opening, and another forming the posterior border. These can be very closely applied to each other, and seem to form a very efficient valvular apparatus, by means of which this useless relic of its larval life may be closed up. The other structure is connected with the mouth. The lower lip Is formed of a fold of skin that is separated from the skin of the throat by a deep groove that runs from the corner of the mouth to hear the symphysis, This fold has a thin sharp edge, and is directed downward and outward. The upper lip also has a sharp edge Which, when the mouth is closed, widely and closely overlaps the lower lip. This arrangement of the lips and that of the gill open- ‘ng seems to me to have relation to the burrowing habits of these animals, and are designed to prevent the mouth and pharynx from being filled with mud. 318 Observations on Amphiuma. The eggs of the Amphiume are the most remarkable that I know of as occurring among the Amphibians. The young, which now constitute the whole contents of the eggs, are surrounded by a trans- parent capsule about as thick as writing paper, and these capsules are connected by a slender cord of similar substance. It is as if the gelatinous mass surrounding the eggs of the toad should become condensed into a solid covering and a connecting cord. How many strings there are of these eggs I cannot determine with certainty, on account of their being inextricably intertwined ; but, since there are four ends visible, there are probably two strings, one for each oviduct. For the same reason I have not been able to count the eggs. A careful estimate makes at fewest 150 of them. The eggs, in their present state, are nearly globular, and average about 9 mm. in diameter. Their distance apart on the string varies from 5 to 12 mm.; fourteen of them were counted on a piece of | the string nine inches long. At this rate the whole mass would - form a string about eight feet long. The connecting cord varies — from 1.5 mm. to one-half that diameter, The eggs greatly resem- ble a string of large beads. | The young are coiled within the capsules in a spiral form. On removing them and straightening them they measure about 45 mm. in length. The color is dusky above, with indications of a darker dorsal stripe, and on each side a similar darker band. Below, the color is pale. The body is proportionally stouter than in the adult and the head broader. The fore and the hind feet have each three toes. ; The young possess conspicuous gills; and, since they are evi- dently near the period of hatching, it is but fair to suppose that they would continue to retain these gills for some time after exclu- sion. The gills are three in number on each side, and are simply pinnate in form. The median gill is longest, measuring some 9mm. in length. From its main axis there arise about ten delicate twigs The other gills are somewhat shorter, and give origin to about eight lateral twigs each. In all these filaments may be seen the blood- Observations on Amphiuma. 319 vessels filled with the large blood-corpuscles for which Amphiuma is noted. Three gill-slits are open, of which the two posterior become cloged in the adult. The eyes appear to better advantage than later in life. k The finding of these young, nearly ready for active life, in such an unexpected situation suggests some interesting problems. At what period of their development are these eggs deposited? If at an early period, the mother must incubate them for a considerable time. If ata late period, why should they be placed in such a situation? In either case it appears to be quite probable that they are fertilized before they are deposited. Again, how are the eggs in such a dry situation saved from being thoroughly desiccated ? They are, I think, kept moist by the body of the mother as she lies coiled around them. My remembrance of her as she lay when first exposed is that she was much plumper than she now appears in alcohol; and when she was laid down on the office floor every spot - she touched was made wet. The source of this water I do not know ; but it appears probable that it came from the numerous glands that fill the skin, and that the mother makes nocturnal visits to the water to lay in supplies. Another question to be considered is this: What is to become of the young when they are hatched? How can these feeble little animals make their way to the water some rods away over ground that is covered with rubbish, dry, and full of cracks? How is it brought about that their delicate gills are not withered when exposed to the dry air? Is it possible that, like some species of snakes, the young crawl down the mother’s throat while she car- ries them to the water? It has been suggested to me that just before hatching she may carry the eggs in her mouth to the water; but the whole mass could not be taken into the mouth, and she could only carry them as a dog carries a large bone. It is evident that we have several things yet to learn about the habits of Amphiuma. By means of dissections and microscopical sections I have made Some observations on the structure of the young of the Amphi- uma as they were found in the eggs above described. A thorough study is being made of these embryos, and I hope soon to pub- 1 a paper giving details and drawings. I here note the most salient features of the skull and shoulder girdle. 320 Observations on Amphiuma. As might be expected of the young Amphiume, hatched in a situation removed for some distance from the water in which it is to pass the greater part of its life, and to which it must with some difficulty find its way, its whole organization is in a far more advanced stage of development than is that of those Amphibia which are excluded directly into their yielding native element. A com- parison of the skull of the young Amphiume with that of the lar- val axolotl, as described by Messrs. Parker and Bettany, shows that the former corresponds in many respects to the earlier phases of the fifth stage of the latter. The axolotl in this stage is 1} inch in length, but when hatched was only about one-third of an inch long (Morphology of the Skull, p. 107). One of the most interesting features of the skull is the deficiency of cartilage in some regions. The otic capsule is well developed and large. Enclosed within it are the semicircular canals and a large otolith. The notochord runs well forward and is partially en- sheathed with bone. The exoccipitals, also, are ossified down almost to the notochord, and the ossification extends into the condyles. On each side there is a narrow band of cartilage that rises up from the hinder end of the ear-capsule toward the middle line, but it lacks considerably of meeting its fellow. Nowhere does the cartilage extend to the middle line above the brain, and nowhere is the brain- cavity roofed over with bone. In the basilar region there is on each side of the notochord a large elliptical fenestra in the cartilage, 50 that there is only a narrow band lying along each side of the noto- chord, and a very narrow strip attached to each otic capsule. The trabeculee are united around the extremity of the notochord, and send back on each side a process to the otic cartilages. These tra- beculæ enclose a very large oval pituitary space. They are narrow and, meeting in front in the ethnoidal region, coalesce for a very short distance. ‘There are very short decurved cornua and narrow bands that run outward beneath the nasal sacs. From each trabe- cula there is given off on the outside a band of cartilage that runs forward and outward, and near its termination sends outward a narrow strip of cartilage over the posterior end of the nasal sacs. This process I regard as the antorbital. There is what appears to be a small postpalatine and a small pterygoid cartilage that does not extend back to the suspensorium. The latter is broad and 18 directed forward. There is a stapes with the facial nerve passmg Observations on Amphiuma. 321 beneath it. Meckel’s cartilage runs forward nearly to the symphy sis. The hyoidean arch consists of a short hypohyal and a longer- ceratohyal. The latter has along its inner side a narrow and easily separable splint of bone. The branchial apparatus is much as in the adult. The first arch is partially ossified. No other ossifica- tions than those mentioned are found in the cartilaginous cranium. There are several membrane bones. A large parasphenoid under- lies the pituitary space and the basilar region. In front of this, in the roof of the mouth, are dentigerous vomers. The maxillaries are probably not represented by actual ossifications, but two rows of dental papills shows where they will appear. There is no palatine or pterygoid. The premaxillaries are present and completely con- solidated. Their nasal spine is long and they bear prominent teeth. The side walls of the skull are ‘protected by small frontals and larger parietals, but it is the frontal process alone of the parietal that is present. The suspensorium is partially covered by a squamosal, The Meckelian cartilage appears to be ensheathed, as in the adult, by only two bones. One of these is the dentigerous dentary, which almost meets its platetrope at the symphysis. The other, lying along the inner side of the mandible, extends from the posterior extremity of Meckel’s cartilage to a point two-thirds of the distance to the symphysis. It may be regarded as an angulo-splenial. It no teeth, as does the splenial frequently in the urodeles. The shoulder girdle consists of scapular, coracoidal and precora- coidal portions, with no ossifications. These elements lack much of meeting in the middle line of the body below. There are a hume- Tus, radius and ulna, carpals and phalanges. The humerus alone has a center of ossification. The anterior vertebrae, at least, are ossified, the neural arches having coalesced with the sheath of bone surrounding the notochord. The upper portion of the neural arch is not yet ossified. Only cursory observations have been made on the brain. Asa _ whole it is far less elongated than in the adult. This shortening is a Principally to the prosencephalic lobes, more than half of whose ength lies alongside of the di- and metencephalon. Laterally, the €pencephalic folds run so far forward as almost to touch the poste- nor extremity of the cerebral hemispheres. 322 Evolution in the Plant Kingdom. EVOLUTION IN THE PLANT KINGDOM.! BY JOHN M. COULTER. a. I should apologize for selecting a subject that has anything to do with so hackneyed a theme as evolution; but you will discover that I intend neither to explain nor defend it. In this presence neither should be necessary. The purpose is to give an illustration of evolution from the plant kingdom, chiefly because illustrations of this law are commonly taken from the ani- mal kingdom, and also because the case among plants is even more striking. One who staggers at the evolution of the horse can find among plants such interminable intergrading that fixity of species becomes a dream of the past, when they were arranged like puppets that popped up in their places when called for, always looked just alike, and were perfectly expressionless. Zoologists are fortunate in having as their stock-in-trade forms of life in which man is specially interested, both as an acquaintance and a kinsman.. The public that listens with pricked-up ears and discusses endlessly concerning the evolution of birds, mammals and man, and thus brings a certain popularity to zoology, cares not a straw for the wonderful structures of Gymnosperms and Lycopods, although furnishing irresistible arguments in favor of a theory that has revolutionized scientific thought. One sort of compensation has been that botanists have been considered a sort of harmless folk, while zoologists are “ infidel,” or “ progressive,” apostles of dark- ness or of light, according to the standpoint of the speaker. Botanical work has been no less effective and advanced in these latter days; but it lacks that possibility of spectacular display which would keep it in the mouth of the public. Monkeys and men the public wants to know about, but Pteridophytes and Phan- erogams are decidedly prosy. It will be found, however, upon a fair examination, that Botany 1 Presidential .Address before the Indiana Academy of Science, December 28, 1887. Evolution in the Plant Kingdom. 328 and Zoology are so mutually dependent and helpful that one can- not advance without the other, and the thoughts of both upon such a great question as evolution are practically the same. Turning aside, therefore, from the broad and much-travelled highway which leads from the Moners to Man, we will strike into a by-path, which extends from Protococcus to Phanerogam, and point out a few of its most salient features. Zoologists should be inter- ested in noting how the same ideas have been worked out in the into great kingdoms, and all should remark the wonderful unity: of purpose pervading the whole domain of life. I shall make no attempt to outline a great scheme into which every plant, however formed, shall fitly fall. If I were younger or less acquainted with botany, I could do this; for a young botan- ist usually begins by attempting to remodel all existing schemes of classification, just as a young college graduate can put veteran statesmen to shame. Botanists have no family-tree arrangement for plants, and will not attempt the construction of one until they know more about the life-histories of the lower groups and more about structure in all the groups. As Dr. Farlow said, in his Vice- Presidential address before the last meeting of the American Asso-. ciation for the Advancement of Science: “On abstract grounds alone, I presume that few botanists would object to the statement that all plants have developed from simple ancestral forms which were nearly related to some of the lower animals. But when it comes to saying in anything like a definite way that certain exist- ing forms have arisen from other lower existing forms or their imme- diate allies in some past epoch, and so on, until the lowest form is reached, botanists may well insist that imagination should not be allowed too large a scope in supplying missing links. It is precisely. in this point that zoologists have an advantage over botanists. The palzontological record of lower animals is more complete than that of lower plants, so that where the zoologist might reasonably form an hypothesis the botanist must rely more on his imagination, until ìn the end he finds himself in the possession of a chain composed, to a considerable extent, of missing links. As it is, if we would con- sider the evolution of plants, not getting much light on the pro- gress of the lower forms from paleontology, we are _ to trust largely to plants as we now find them, and to ask what are the inferences we are permitted to draw from existing structures and conditions,” : . 324 Evolution in the Plant Kingdom. Not so very long ago it was thought that at least one fact in classification was impregnable, viz., that there were two great and very distinct groups of plants, called Phanerogams and Crypto- gams. These two were set off against each other as antipodal groups, between which: there was nothing in common. Unfortu- nately, the names given to these groups were simply an expression of the botanical knowledge of the time. ‘ Apparent reproduction” ‘and “ hidden reproduction” may have correctly expressed the facts with respect to these two groups once ; but they are very far from do- ing so now. The modern botanist, with his more complete appliances and methods, has begun to resolve the great nebulous mass of Cryptogams, and has discovered in it distinct systems and groups. The whole subject of Cryptogamic classification is, of necessity, — quite inchoate. Certain groups and relationships have been dis- tinctly defined; but among them and around them there float numerous hazy forms that refuse to be classified. Our knowledge is not sufficient to attempt the work with any degree of certainty, but certain broad principles have been struck out which will serve to guide. It is known now that Phanerogams form but one of several. cor- relative groups. The most useful scheme of classification at present makes the number seven. These seven primary groups must be. considered merely as convenient pigeon-holes i in which to distribute our facts. It is not my purpose to go into the details of any supposed order of evolution of the plant kingdom, but to give some general thoughts concerning it and to trace through the development of a single structure. Generalization is always easier than details; for in it one is never embarrassed by the facts. It seems probable that the plant kingdom must have begun in some such form as Protococcus, the common green slime found stain- ing foundation stones, bark, etc. It surely represents the unit of structure and of function in the vegetable kingdom. We can con- ceive of no simpler plant-form than a single chlorophyll-bearing cell. Some of you will recall the fact that we have unicellular plants without chlorophyll, such as yeast and bacterial forms; as well as forms called plants that seem to be mostly naked proto- plasm, such as slime moulds; but the former probably represent degraded forms, while the aniinal or plant character of the latter * Evolution in the Plant Kingdom. 325 remains in doubt. At any rate, they probably have a far greater complexity than was formerly supposed. We have thus come to consider protococcoid forms as our foundation-stones in rearing the structure of the plant kingdom. Through all the Thallophytes {representing the four lowest of our seven primary groups) there run two parallel lines, the typical or normal plants, containing chlo- rophyll; and the degraded plants, which are destitute of chloro- phyll. This distinction is a very deep-seated one in the plant kingdom, for chlorophyll-bearing plants alone can do normal plant work, viz., the conversion of inorganic to organic material through the agency of chlorophyll and sunlight. Plants without chloro- phyll must live as parasites or saphrophytes, a degraded habit which leads to degraded structure. The former in the first four groups, are called Algæ, the latter Fungi. The general opinion, brought out clearly in the address of Dr. Farlow, already referred to, is that Fungi are degraded representatives of Algæ—relatives in reduced circumstances, whose lazy habits of parasitism have entailed upon them degenerate bodies. Just what Fungi have descended from what Alge it is perhaps impossible to say. The chances are that some of our important Fungi are degraded rep- resentatives of algal forms which no longer exist. Specific state- ment with regard to this relationship is little better than guess- ing; but the general proposition seems to be fairly well established. We have advanced, then, thus far: that of the two parallel lines, Algæ and Fungi, which run through the four lowest plant groups, the plant kingdom is to be considered as having advanced in the line of the Algæ, the chlorophyll-bearing line; while the Fungi are simply so many degraded forms, which lie strewn along this line of general progress, like drift wood stranded along the banks of a stream. For our purpose, then, the Fungi are to be dismissed, their probable origin having been sufficiently indicated. Starting, then, with protococcoid forms, advancing along the lines of Algæ, and into the chlorophyll-bearing members of the groups above, what notions of evolution can be obtained? Examining our present schemes of classification it will be discov- ered that chief stress is laid upon the methods of sexual repro- duction. It is, as yet, the best thread upon which our facts can se strung, and it usually expresses so thoroughly the highest effort on the part of the plant, that as it advances from simplicity to ae 326 Evolution in the Plant Kingdom. extreme complexity it seems but fair to consider it a good index of relative rank. I intend to give in merest outline the develop- ment of sexual reproduction, guarding such an attempt with the following statements :— 1. This is taken as but a single striking line of development, and must be understood to be accompanied by many other ‘details in asexual reproduction and vegetative structure which bear it out but which we have no occasion to mention. Just as in describing the evolution of the horse the toes arè seized upon as the one among other structures most striking and most simple of presentation. 2. There are hosts of side issues which represent departures greater or less from this general line of advance, and which cannot be taken into account in this general sketch. In general, they can be all explained by the law of adaptation. 3. Even the line I propose to follow can be but imperfectly pre- sented ; as there is not knowledge sufficient to make it as complete as we would like it, and not time enough to present it as complete as we know it. Taking, therefore, this thread of sexual reproduction as a guide through the labyrinth of plant forms, we may come to some glim- mer of light. Naturally, the lowest group would contain those plants in which no sexual reproduction has been discovered. In recognition of this position, as well as their probable position in point of time, they have been called Protophytes, or “ first plants.” The lowly char- acter of lacking sexual reproduction is further borne out in their structure, for they are mostly one-celled forms. In this group stands Protococcus as a type, a single-celled chlorophyll-bearing plant with no discovered sexual reproduction ; and, as degenerate representatives, the bacteria and yeasts. You will notice, however that the definition of this group, on the basis we have adopted, is a negative one, being not as much what we have found, as what we have not found. It follows that this group furnishes a kind of limbo to which all one-celled plants are consigned, in case no sexual reproduction is found, a sort of unresolved nebulous mass, in fact, a cloak for ignorance. It is like the man who undertook a great scheme of classification, and made his two principal divisions “ things that I know ” and “things that I don’t know.” The first group he could classify reasonably well; the second he did not have to classify. Evolution in the Plant Kingdom. 327 In this lowest chamber of Protophytes, every now and then the garment of sexual reproduction is discovered, and its wearer invited to take a place in some upper chamber. But the chances are that the chamber will never be completely emptied, and that there will always be some plants called Protophytes. In the second group we would expect to find the beginning of sex-reproduction in its simplest form; and to understand what the simplest form would be, the nature of sex-reproduction must be defined. It consists in the mingling of the contents of two cells to form a new one. This new cell is the progeny, and develops more or less directly into the structure of the parents. Applying this definition to some one-celled form as Protococcus, the simplest possible method of sex-reproduction would be for two cells to come in contact and mutually discharge their contents into a blended mass which becomes a new cell and presently resembles the parents. Such is the beginning of sex-reproduction as we find it in the second group of plants; but it will be noticed that there is no distinction of sex. Both cells are constructed alike and act alike ; neither is receptive, for the new cell is constructed upon neu- tral ground. Sexuality has been attained, but not bisexuality. For this reason, the second plant group is frequently called -the “Unisexual Group”; or, from the fact that the cells are for a time yoked together, they are technically called Zygophytes, or “ Yoked Plants.” In this group, not only is sexuality begun, but bisexu- ality is hinted at. Plant bodies now begin to consist, not of single cells, but of cell-groups, usually arranged in a chain, forming fili- form or thread-like plant bodies. In these filaments or chains of cells, any cell (for they are all alike) can become a reproductive cell and join issues with any other cell, either in the same filament . rin another. There is no setting apart of special cells to do this special work, for it is done equally well by all, and all are ordinary vegetative cells. The first hint at bisexuality comes with the fact, — that one of these conjugating cells becomes receptive, receiving the contents of the other, and within it the spore or progeny cell is formed. Such is the case in the common Spirogyras, or “ frog-spittles.” Although one cell becomes receptive, there is no difference in form nor in contents, and it seems immaterial which becomes the receptive one. In other forms, the development of the spore within acai 328 Evolution in the Plant Kingdom. receptive cell demands more or less change of form, thus making a cell differing in appearance from the ordinary ones. To sum up the general phases of this advance in the second group, or Zygo- phytes; sexuality is attained, at first with no distinction of sex ; then one cell becomes receptive, but differs in no respect from any other in form or contents; and finally, the receptive cell becomes more or less changed in form by the development of the spore. In the third group we would expect to find bisexuality distinctly worked out, but of the simplest kind. The simplest kind of dis- tinct bisexuality would consist in setting apart two cells for the special performance of this function, differing from the ordinary cells of the plant body and from each other in form and contents. Naturally the receptive or female cell, in which the spore is to ` develop, would be the larger, probably the largest cell produced by the plant. Such is the average condition of sexuality in the third group, called Odphytes, or “ egg-spore plants,” in reference to their large spores. It is to be noticed that these male and female cells differ in form and function only from the ordinary cells of the plant body ; they are not favored and cared for by any sort of pro- tection. At this point we are confronted by a phase that needs explanation. The life-history of every plant may be consid- ered a cycle, from the spore which produced it round to the spore which it produces. The cycle is traveled continuously without cessation, except at some one point, which is known as the “resting stage.” Every plant, in the life cycle referred to, must, at some point, pass through a resting stage, in which condition the plant activities lie dormant, as if to gather strength for the rest of the journey. This stage must always be a protected one, protection which not only shuts out adverse external conditions at a time of low vitality, but prevents response to favorable ones until after a certain lapse of time. In the groups already considered, this resting stage occurs at the spore phase. The protection provided is simply a thick heavy wall about the spore itself; and in this condition the plant exists for a time and then runs its cycle, round through parent form to spore again. To pass through the resting stage at the spore phase is characteristic of a low type. In the third group the resting stage is pushed gradually forward, until the sex-spore becomes, not a rather permanent phase, but simply one of the transient phases, the resting stage occurring after the spore has developed subsequent structures. , * Evolution in the Plant Kingdom. 329 The next phase in the sex-reproduction, the one naturally expected in the fourth group, is the protection of the male and female cells or organs. Set apart heretofore in form and function, they are not protected ; but in the fourth group this is gradually and at length very completely provided for, as indicated by the group name, Carpophytes, or “ plants with spore cases.” In cer- tain members of the group—those which look towards Oöphytes—the male and female cells are at first as naked as in Odphytes, and if the spore passed into the resting stage the plants would belong to that group ; but the spore, as soon as formed, proceeds to develop other structures, and, along with the female cell in which it is con- tained, develops a complex structure called a spore-case, and this is the resting stage. Summing up the advance made in the fourth group, we find male and female cells distinct in form ; the latter finally protected ; and the sex-spore ceasing to be the resting stage, and becoming an evanescent phase which passes directly into a complicated structure, which itself is the resting stage. Subsequently, from this compli- cated structure, or “spore-case,” forms like the parent plant are produced by means of so-called spores, not formed by sex-union, but by ordinary cell division, and for that reason called asexual Spores, They are simply reproductive bodies cut off from the parent stock, and are chiefly for the dissemination of the plant, no more a product of the sex act than the buds used in grafting or the “slips” in transplanting ; but they are the “ spores” commonly spoken of among cryptogams, and their name is legion. The essential difference between sexual and asexual spores cannot be too Strongly pointed out, for they have led to endless confusion of ideas. Note now the relation of things in this fourth group. The sex-spore produces the structure called the spore-case, which in turn produces asexual spores by ordinary cell division, which in turn reproduces the original parent. In this group, therefore, in the effort to protect the progeny the resting stage was pushed forward, ma that condition of things known as “ alternation of generations ” originated. As a result, we have in a single life-cycle two plant Phases, each producing spores, but in a very different way. One phase bears the sex-organs and produces the sex-spore, and hence is called “ the sex-plant ;” the other is produced by the sex-spore, no sex-organs, produces asexual spores, and hence is called — 330 Evolution in the Plant Kingdom. “the asexual-plant.” The asexual spores produce the sex-plant again, and so the cycle is completed. The idea of protecting the sex-organs or their progeny, begun in the fourth group, becomes more and more fully developed in the groups above. After the covering to the female-cell is established there remains a neck-like passage-way. This passage-way becomes more elongated, and more or less guarded, until in the highest group it too is com- pletely blocked up by loose cellular tissue, which must be pene- trated by what is called the “ pollen-tube.” To summarize at this point: we have an asexual group as the lowest; then a unisexual group; then a bisexual one; bisexuality appearing as the goal in the first three groups. In the fourth appears the idea of protection, which gradually becomes more and more perfected in method, until, without any sensible break in the series, we reach completest protection in the seventh group, or Phanerogams. Also in the fourth group, after bisexuality had been attained, we find alternate generation, and it is in the devel- opment of that character that we find the most striking lme of advance from the fourth group to the seventh. Keep in mind that the same road is also completely graded and bridged by way of “protection,” as has been already referred to. Given, then, as our starting-point (1) a sex-plant which carries sex-organs and produces ə sex-spore; and (2) a resulting asexual plant which produces asexual spores; and remembering that the two are but arcs of the , same circle and alternately produce each other, what is the next complication that indicates advance ? = The next step, besides the completer protection already referred to, is the completer setting apart of the two phases, so as to make them in structure what they are in function, distinct plants. In members of the fifth group, mosses for instance, we find this to be the case. The ordinary moss-plant, which bears the sex-organs, 15, of course, the sex-phase ; and borne upon it, though as organically distinct as if it grew upon any other mechanical support, we find the structure which develops from the sex-spore, the so-called “fruit,” or spore-case. This is the asexual phase, and produces within itself asexual spores (the only spores: meant in the ordinary description of mosses). These spores, in turn, produce the sex- phase, or ordinary moss-plant, and the cycle is complete. There 1$ here a distinct setting apart in function, and, as usually follows, ™ . Evolution in the Plant Kingdom. 331 form also. To the one phase is assigned sex-reproduction ; to the other the dissemination of the plant by asexual spores. The ordi- nary vegetative structures, representing root, stem, and leaves in the higher groups, are here included in the sex-phase also; so this phase is the prominent‘one, the one ordinarily observed and spoken of as “the plant ;” while the asexual phase is more inconspicuous, and, being mechanically borne on the other, seems to be but a part of it. From this point on, the tendency is to confine the sex-phase more and more entirely to the business of sex-reproduction, and to transfer the vegetative structures more and more completely to the — asexual phase. The result is, that as we advance towards the higher groups the sex-phase becomes less and less prominent, as the function is taken away from it which involves size and display ; while the asexual phase, taking on the function involving display, becomes more and more prominent, and is popularly styled “the plant.” So that, while “the plant” in the case of mosses is the sexual phase in the life-cycle, “the plant” in higher groups is very probably the asexual phase, representing the so-called “ fruit” of the moss, As the sex-phase is to be more and more confined to Sex-reproduction, it can easily be understood how it can be reduced more and more, until it has only the cells actually needed ; and these cells may be reduced to two, one to represent the plant, and the other the sex-organ growing upon it. This seems to represent the goal set before the sex-phase, when in the sixth group the vegeta- tive structures begin to leave it. From this point on evolution reduces and simplifies the sex-phase, increases and makes more and more complex the asexual phase. The sex-phase thus begins simply in the lowest groups and ends simply in the highest, reach- mg in the fifth probably its greatest complexity. While this is true of the structure of the sex-phase, it is not true of the sex- function, for the very highest possible degree of differentiation in this regard is attained in the highest group. In the sixth group, represented by ferns and their allies, we find a very wide distinction between the sexual and asexual phases ;. the latter having become very prominent and having possessed itself of most of the vegetative structures, being the ordinary fern- Plant, with its great display of vegetative structures and asexual Spores, but no sex-organs. Linneus may well have examined 332 Evolution in the Plant Kingdom. the fern in vain for any evidence of sex-organs, for he only knew of this prominent asexual phase, and in his despair con- signed the group to “Cryptogams,” “hidden sexuality.” The asexual spores (borne, you may remember, upon the leaf-struc- tures of the fern) develop, of course, into the sex-phase; but that is so small and hidden among the mold in which the spore has fallen, that it may well escape observation. It is simply a minute flat disk-like body, with vegetative cells and root-like processes enough to make it able to live long enough to accomplish its function of sex-reproduction. But it bears the sex- organs, produces the sex-spore, and from it there arises the beau- tiful or stately asexual plant. The reduction of the sex-phase could go no further than this, and at the same time compel it to make its own living from soil and air. If any more reduction be made, the sex-phase cannot be organically separated from the other, but must depend upon it for elaborated food. By this means the utmost possible reduction could be reached, and we must expect this to be the next step in advance. For instance, the asexual spores of the fern are scattered over the soil. From them springs the reduced sex-phase, known as the prothal- lium, and capable of independent existence. Any further reduc- tion, which would make it incapable of independent existence, would necessitate that the asexual spore be not separated from the asexual plant, but developed into the prothallium upon it so as to receive elaborated nourishment. The reason why a prothallium cannot be indefinitely reduced, and still retain the power of inde- pendent existence, is not far to seek. It is on the same principle that a small battery cannot work an indefinite amount of wire. The formation of high-grade reproductive cells is an exhaustive work, and it would require more than a few cells to manufacture such an amount of highly organized substance from crude material. Hence we reach a point, beyond which it would be a physical impossibility to reduce the prothallium, without arranging tO supply it with material already highly organized. Remembering, then, that from the sixth group, represented by ferns, higher rank is to be marked by a reduction of the sex-phase or prothallium, which finally cannot be separated from the asexual plant, let us note a new phase of differentiation which begins to be prominent in the upper members of the sixth group, and continues Evolution in the Plant Kingdom. 333: as the highest expression of differentiation in the seventh and last. Although vegetative organs have departed from the sex-phase, there still remains a double function, namely, the production of male and female cells or organs. It seems to bea law, that so long as anything remains to be differentiated, differentiation will con- tinue; and the separation of the sex-organs is its next possible: expression. Instead, therefore, of having .a single prothallium bearing both male and female organs, we find two prothallia ; one male and the other female. This state of things is reached by one set of organs first becoming functionless, and finally being sup- - pressed. Remembering that these prothallia are developed from asexual spores, it does not seem strange that this dicecism extends presently to these spores themselves, and that we soon find what may be styled (from the nature of their product) male and female asexual spores. This brings us to the heterosporous arrangement, a feature which continues to the last, and which must be considered a high-rank character, possessed only by the higher members of the sixth group, and by the seventh; and yet, through the very midst of this condition of things, accompanied as it is by many intergrading characters in all the other plant structures, the old abyss between Cryptogams and Phanerogams was supposed to run. To sum up the lines of advance, with which we enter the group Phanerogams, we find male and female spores, producing male and female prothallia, and those prothallia so much reduced that not only do they not become separated from the asexual plant, but are developed within the asexual spore itself. But these same important characters are to be found among the highest Crypto- gams, and we must conclude that any line of separation is one of our own drawing, and has no representation in nature. It remains to apply to the well-known parts of any flowering plant the terminology that we bave been using in outlining the evolution of the sex-apparatus, The asexual phase, or part of the cycle, is “the plant” with its rich display of vegetative organs, Consisting of root, stem, leaves, and their various modifications. This asexual phase produces asexual spores of two kinds, called | male and female, because they are to produce male and female prothallia. It would be an interesting line of development to note the gradual differentiation of the apparatus for making these asexual spores, but that is aside from our purpose. The 334 Evolution in the Plant Kingdom. final result is, that in the flowering plant we are considering, highly specialized sets of organs produce the two kinds of asexual spores, which have been called pollen-grains and embryo-sacs, It seems strange to be forced to give up pollen-grains or embryo-sacs as sexual affairs, for in our old notion of things they represented thre very essence of sex; but the fact remains that they are asexual spores and simply give rise to prothallia which bear the sex-organs and give rise to the sex-spore. i The two prothallia which are developed from these asexual spores - have reached the highest degree of reduction, developing within the spores themselves. In the case of the pollen-spore two or more cells. are developed, which may be easily seen by the use of the proper reagents, and this small group represents the male prothal- lium, one of the sex-phases in the life cycle. This much reduced plant sets apart one or more of its cells to do vegetative or growth . work, and another to be the male organ. A very vigorous growth of this prothallium is demanded in the development of the pollen- tube, through which the male cell discharges its contents. This pollen-tube does not usually find an open passage-way, but one that is blocked up with spongy tissue, called “conductive tissue,” through which it makes way like a parasite invading the tissues of a host plant. In the case of the embryo-sac, the female asexual spore, the development of the prothalliumr is still feebler, the cells representing it not only being few in number, but free from each other,—a sort of disorganized tissue. The cells representing the female organs are clustered near the apex of the embryo-sac, forming what we now call the “ egg-apparatus,” while those that probably represent the vegetative cells of the prothallium -are clustered at the other end of the embryo-sac, and are styled “ antipodal cells.” In pines, representing the lowest group of flowering plants, the female pro- thallium is a very distinct and compact tissue, bearing regulation female organs, the so-called “corpuscula.” This but shows their position upon the lower border line of Phanerogams. The sex- phase in the life cycle, therefore, which in mosses stood for the whole plant as we ordinarily recognize it, in Phanerogams has become reduced to little clusters of cells developed within the pollen-spore and embryo-sac, so inconspicuous that it has remained for the modern reagents to discover their existence. The real sex- Recent Literature. 835 spore, or oöspore of Phanerogams, is the single fertilized cell in the embryo-sac, which at once develops into the embryo, at which point Phanerogams pass into the resting stage, in this group called “the seed.” The sex-spore, since the fourth group, has become such an evanescent thing, so out of reach of common observa- tion, that very naturally it has been the common opinioņ that the comparatively permanent asexual spores are sex affairs. Sex- spores are directly formed by sex-union; while pollen-grains and embryo-sacs are never formed in any such way. Thus have I hastily traced one of the principal threads upon which our botan- ical facts are strung. And as one examines the subject in more of its details, he becomes irresistibly impressed with the idea that here is a great scheme of development, directed by laws of which we are beginning to catch glimpses, and by which the whole fabric of a great kingdom has been beautifully and continuously worked out, RECENT LITERATURE.

Most of the alleged — 336 Recent Literature. plants of the Cambrian and Silurian seas are thrown out, but Nematophyton, Protannularia, and some species of Buthotrephis are marked as genuine. A special feature is the working out more elaborately than in any other place of his theory of an early Rhi- zocarpean flora culminating in the Devonian. Much space is given to the flora of this period, so well developed in Acadian territory, and so unimportant in other countries, and his name “ Erian” is constantly used and specially defended. The Carboniferous flora takes a subordinate rank, but the extended notes to that chapter are crowded with valuable information, much of which would be new to any but the thoroughly informed specialist. The early Hill, is also well characterized and illustrated. The great Mio- cene flora, which ranks next in abundance to the Carbo is passed over nearly in silence, but some very important deduc- tions are drawn from the little florula on Green’s Creek, central Canada, in the Leda clay, believed by him to have been deposited at about the time of maximum glacial refrigeration. The work closes with a chapter on the origin and migration of plants, and fl ontology. A few of the more important of these may be men- tioned here: He accepts and reiterates the Brongniartian hypo- thesis of the greater abundance of carbon dioxide in the atmos- phere during paleozoic time, but without denying the possibility of the cosmical origin of portions of it, as maintained by Dr. T. Sterry Hunt. He insists upon the substantial uniformity of the Recent Books and Pamphlets. 337 trunks he inclines to the opinion that these will yet be found attached, and that some forms, at least of Sigillararia, must have n coniferous. In this connection he discredits the statements of Goldenberg relative to the fruits of Sigillaria, but seems to be unac- gante with the important paper of Zeiller, which has certainly one more to settle the question than any other discovery.

Steains before the Royal Geographical Society, appears small when com- ed with the mighty rivers around it, yet has a length of rather over four hundred and fifty miles. Its head-waters are several streams rising in the Serra da Mantiqueira, the loftiest peak of which, Itatiaiaassu, 10,040 feet, is the Dieb known elevation in Brazil. The various streams whieh unite to form the Rio Doce flow in a more or less northerly direction from the northern slope of the Serra and unite into a main river which, after receiving several tributaries, enters the ocean at about 19° 40’ south latitude. The Serra da Mantiqueira has a general northeast direction, but the nee E'S line of the Brazilian coast-range is continued northwar by the Serra dos Amore, which is cut through by the Rio Doce in its descent from the interior tabie-lands. The part of the Rio Doce basin lying east of the last named Serra is a deadly wooded low- land, sloping upward to a height of about nine hundred feet, and resolving itself near the coast into a stretch of alluvial ground, Figueira—on the banks of the Doce, though for the greater part 0 its course grand virgin forests, filled with a hundred varieties 1 Edited by W. N. Lockington, Philadelphia, Pa. Geography and Travel. 341 the choicest timber, come down to the water’s edge in a wall of gloriously wild tropical vegetation. The valley is the home of the Botocudo, who has not yet renounced cannibalism. Mr. Steains does not place the number of these Indians at more than seven thousand, yet states that they form the sole barrier to colonization. Espiritu Santo, the province lying east of the Serra Amores, is at present the poorest province in the empire, and the valley of the io Doce is a great gap in the wall of civilization that has been slowly reared along the four thousand nine hundred miles of the Bra- zilian seaboard. There is not in Brazil a tract naturally richer than that which lies between the Doce and the Mucury to the north of it, yet the Indian is still in possession. he Botocudos, so called by the Portuguese on account of the “botoque,” or lip-ornament, which is the only clothing worn by them, are about five feet four inches in height, broad chested and lean limbed, and with small hands and feet. The plug of wood is first inserted in the under lip when the Indian is three or four years old, and is replaced by a larger until a diameter of three inches is attained. If the lip splits the Indian ties the ends together with bark. The “botoque” is now worn only by the older members of the tribes. The nuts of two or three species of palm form the chief sustenance of these primitive people, and the supply is eked out with game and fish. Mr. Steains ascended the tributaries Tamba- quary, San José, Pancas and Rio San Antonio. the discussion which followed the reading of Mr. Steains’ paper, Mr. C. Mackenzie stated that the custom of wearing an orna- ment in a slit made in the lower lip could be traced with very few breaks from the Eskimo of the Alaskan coast to Brazil. THE Casstqurart.—M. Chaffanjon, the well-known explorer of the Orinoco, has carefully studied the communication between that river and the Amazon, by means of the Cassiquiar, and comes to the conclusion that it is of recent origin. The rapid current of the ‘actual overflow in the rain season, has produced a permanent sagas The clay deposits on the left bank have a slope towards mazon. . _ ÅSIA.—EXPLORATIONS IN NEPAL AND TIBET.—An adventurous d aey through Nepal and Tibet has recently been taken by M. „ 4 native explorer attached to the East Indian Survey.

Everest, the governor refused him further , but he succeeded in “o that functionary’s daughter-in-law a goitre, and soon after } with her husband on a trading expedition into Tibet. The pass 342 General Notes. over the Himalayas, called the Pangula, is about 20,000 feet above the sea. More obstruction was met with at Deprak, the frontier village of Tibet, but leave to advance was at length obtained from the governor of Dingri, who exercises all civil and military jurisdiction over a large tract of Southern Tibet. Dingri has about 250 stone houses, and stands at an altitude of 13,360 feet. From Dingri the explorer proceeded by the Digurthanka plain and Palguche lake (said to have no outlet) to Jonkhajong, the most northwestern point reached. Hence he went southwards to Kirong, followed the Tusuli river for awhile, visited Nubri and Arughat (Nepal), and finally, via Deoghat, reached Tirbenighat, on the British frontier on Jan. 13, 1886. Beyond Kirong, on the Nepalese frontier, the road runs along a gallery of planks laid upon iron bolts driven into the rock. Parts of the plain of Southern Tibet show signs of a former larger population, and it is said that in the last great war between the Nepalese and the Tibetans most of the inhabitants were killed. R. VON LuscHaAn’s JOURNEY IN Asra Minor.—At a recent meeting of the Geographical Society of Berlin, Dr. von Luschan spoke of his explorations in Asia Minor, undertaken chiefly with archeological aims. Dr. Luschan accompanied Otto Bensdorf into Lycia in 1881, and afterwards visited the tomb of Antiochus I., discovered by Otto Predestein in 1882. This is an immense tumulus on the right bank of the Euphrates, between Iskenderun and Bagdad, on the peak Nemrud Dagh (7000 feet). The tumulus is flanked on the east and west by five gigantic figures of gods, sixteen to twenty-three feet high. At a distance of ten days’ journey from the coast, the traveler along this route comes upon the ancient bridge over the Boilam-Su,a single stone arch, sixty-five feet in height and 325 in length. It was built by Septimius Severus, arracalla and Geta, and is to-day in perfect preservation. After- wards Dr. Luschan took part in the expedition of Count Lancko- roviski, the object of which was the archeological exploration of Cilicia and Pamphylia. In other later journeys Dr. von Luschan turned his attention to the complicated ethnography of Asia Minor. The Turco-Mongolian anatomical type is not to be found among the so-called Turks of Asia Minor. The Mohammedans of the peninsula belong to three types, viz.: Old-Grecian, Armenian and Semitic. The race which gave the religion and language was numerically too weak to influence, to any considerable extent, the physical nature of the conquered people. The Greeks exhibit the same three types, the true Greek predominating along the west coast and on the islands. The Armenians are a compact an homogeneous people, anatomically allied to the Tachkadschy or Alleor of Lycia, the Ansarieh or Fellach of S. E. Asia Minor Geography and Travel. 343 and N. Syria, and the Kizilbash and Tezyde of Upper Mesopo- tamia and Kurdistan. The Turukes are genuine nomads, tradi- tionally from the Hindu Kush. urcomans and Kurds also occur, besides Bulgarians, Arnauts, Arabs, Gypsies, Europeans and negroes, all of whom have immigrated in comparatively modern times.

Thonar, who was believed to have Shea in the Gran Chaco, has returned to Port Pacheco with 1S companions, It now appears that Dr. Meyer did not ascend to within 2000 feet of the summit of Mt.

A. Houtum-Schindler (Proc. Roy. Geog. Boc., Feb. 1888), gives a summary of the various barometrical and trigonometrica ` observations that have been made at the altitude of Demavend, the Shest peak of the Elbruz Mountains (Persia), and arrives at a result of about 19,400 feet.

NOTES ON THE DRIFT NORTH OF LAKE OnTARIO, is the title ofa paper read by Professor J. W. Spencer before the Phil. Soc., Wash- ington, March 3d. This short paper is a generalized description of some of the obscure and conflicting phenomena of the drift, of which this notice is an abstract. mongst the deposits of the later Pleistocene period, there is a well stratified, hardened, brown clay, charged with pebbles which are more or less glaciated, resting upon the typical blue boulder clay, north of Toronto. In the Canadian classification of the Pleistocene deposits there is no place for this deposit. Indeed, all of the stratified deposits of this region need revision in the light of the progress that has been made in surface geology during the last twenty years. Thus the Saugeen clay is resolvable into three series. The relation of all the clays to the older beaches require special study, as a part of them probably represent the deep water deposits of the Beach epoch, while some of the later beaches rest upon such clays. Around the head of Georgian Bay there are ridges, in the form of moraines, similar to those about the other Great Lakes, reaching to the height of 1300 to 1400 feet above the sea. From the face of the Niagara Escarpment—between Georgian Bay and Lake Ontario—there extends, for over a hundred miles, to near Belleville, a broad zone, of from eight to twenty miles in width, covered with drift ridges, composed of stony clay below, and fre- quently stratified clay or sand above, having an elevation of 1100 to 1200 feet above the sea, with occasional reductions to 900 feet. These “Oak Hills or Ridges” rise from 300 to 500 feet above the Paleozoic country to the north. The stones in the clay are often glaciated limestone, with only a small proportion of crystalline ebbles or boulders. In the deposits of the ridge native copper . been found; consequently the drift-carrying agent moved southeastward down Georgian Bay, to the west end of the Oak Ridge, and probably throughout its whole length, North and east of Belleville there are many lower and fragmentary ridges, havin a trend somewhat across that of the Oak Ridge. The glaciation o. the region adds great difficulties to the explanation of the phenom- ena. The striation in the Ottawa Valley, from Lake Tamiscamang to the junction with the St. Lawrence, is to the southeastward, with - very rare local exceptions. Of the Niagara ment, between Georgian Bay and Lake Ontario, from 1600 down to 700 feet above the sea, the striæ are also to the southeast; but between these widely separated regions the surface marking of the rocks are Geology and Paleontology. 345 obscured to the west and south by drift, and to the north and east absent or rarely seen, although the crystalline rocks are commonly rounded or very rarely polished, an absence that can only in part be accounted for by subsequent atmospheric erosion. About the St. Lawrence and Lake Ontario the striations are to the southwest or west. Between the Ottawa River and Georgian Bay there is a high prominence, which divided the drift-bearing currents. But north of Lake Huron’the glaciation is very strongly marked, and the direction is to the southwest, with very rare local variations. All the lobes of glaciation about the lakes, from Superior to the Ottawa Valley, radiate backward to the broad and open but low basin of James (Hudson) Bay. The watershed between the lakes and Hudson’s Bay during the epoch of the formation of the drift was several hundred feet lower than now—which is about 1600 eet at present—as shown by the differential elevation of the beaches. For this conflicting phenomena of the drift no explana- tion was offered, but rather sought for. ‘ Some remarks upon the paper were offered by Mr. Gilbert, who had observed the slight amount of erosion in the Ottawa Valley ; but he thought that generalized explanations of the drift were very ‘often contratlictory when applied to special regions, and that our knowledge of the phenomena would not at present give a satisfac- tory explanation. GLYPTODON FROM TEexas.—In the Proceedings of the Philo- ‘Sophical Society for 1884, p. 2, I recorded the discovery of a Species of Glyptodon in the valley of Mexico by Professor Castillo, Which was at the time the most northern locality at which the genus iad been discovered. I can now announce its discovery within the limits of the United States, in Nueces Co., Southern Texas, by my friend, Mr. William Taylor, in the beds which have yielded Equus crenidens Cope and E. barcenæi Cope, both species of the valley of Mexico. The present species is represented but by a single segment of the "carapace, but as the sculpture of these elements is very character- istic, and as my means of comparison are very large, since my Pampean collection embraces a majority of the species, I venture to ‘describe it. It belongs to the group in the genus represented by i pet te Owen, and G. oweni Nodot. It is a species of large Size, with very thick carapace, and with the circumferential areas of the rosette but little smaller than the central one. The former are regularly pentagonal, the latter regularly hexagonal, and they are — by well-defined grooves. foramina very few. The surface of the areas is flat and in one plane. The texture of the median area differs from those round it in being im with numerous small, closely-placed foramen-like fosse. Its sur- face supports no tuberosities. The circumferential areas are marked 346 General Notes. with shallow grooves, which issue abruptly near the median border and radiate towards, and some of them to, the circumfer- ence, becoming shallowed externally; no tuberosities. | Diameter of scutum, 45 mm.; of median area, 17 mm.; thickness, 15 mm, This species is of the same type as that one found in the valley of Mexico, but I cannot speak positively as to its identity. It may be called Glyptodon petaliferus—E. D. Cope.

THE Rootstocks OF LEERSIA AND MUHLENBERGIA.’ — Leersia virginica Willd., grows in wet, shady places, and starts rather late in the spring. Late in autumn the parts below ground are found to consist mainly of some slender exhausted and dea rootstocks, from one to three or four centimetres long. The inter- nodes of these slender exhausted rootstocks are covered for a part of their length by sheaths of rudimentary leaves, early bearing a very short blade. A portion, perhaps one-third, of the nodes bear from one to four thickened, scaly rootstocks, which contain nourishment for start- ing young plants the next spring. In some cases one or more scaly rootstocks appear near the apex of a similar rootstock which survived the winter. The surviving rootstocks are slightly flattened, one to four centi- metres long by three to five mm. in diameter, covered with scales, and are mostly simple, though some of them have short branches. he scales are brown, alternating and two ranked, and on inter- nodes which are from one to two mm. long. The bases of the scales are thickened and abound in plant food. Leersia oryzoides Swartz, also has rootstocks, the main axis of which is not very unlike that of the former species, though in autumn they are rather stouter, and most of them remain alive and gorged with plant food for use on the approach of the succeeding Spring. Many of the nodes bear short, pointed, solid branches, with four to eight nodes. The scales of these buds are mere rings or shreds, and are not filled with nourishment in autumn. he fundamental differences, then, between the rootstocks of these two species are as follows: 1. In winter the main rootstocks of Leersia virginica are dead, while those of L. oryzoides are alive and abound in food. 2. The scales of the rootstocks coming from the nodes of the main rootstocks of ZL. virginica are broad, firm, and full of plant food, while the corresponding scales of the branches of L. oryzoides are reduced to mere dead fragments, containing no plant food. No good specimens of other species of Leersia were examined in ref- erence to their rootstocks. ; A considerable portion, if not all, the species of Muhlenbergia put forth flowering branches. In case of M. debilis Trin., some of the lower internodes from the surface to five or more centimetres above frequently branch at the nodes, where there are clusters of , Edited by Prof. Charles E. Bessey, Lincoln, Neb JA New York Per By ore the Botanical Club of the A. A. A. S, in New > 352 General Notes. bracts or short leaves. The specimens of this species examined were quite erect, not geniculate, nor rooting at the nodes. The culms of M. diffusa Schreb., M. neomexicana Vasey, are much like those of the former species, only they are geniculate, and root freely at the nodes. From those which are geniculate and rooting at the nodes, it is only a step to those which bear rootstocks on or below the surface of the ground. . comata Benth., produces branching rootstocks about five mm. long by one mm. in diameter. ese are covered with thin bracts rather loosely appressed, and from one to two mm. long. They represent the sheaths of leaves only. M. glomerata Trim., has rootstocks much like those of M. comata, only the internodes are a little shorter and the appressed scales more abruptly pointed. M. willdenovii Trin., has rootstocks which are rather larger, with internodes still shorter (14 mm.), the scales broad, appressed, and more abruptly pointed than either of the previous species of Muhlenbergia. The scales of M. mexicana Trim., are rather short, and bend abruptly away from the rootstock. The scales of M. sylvatica (T. and G.), are much like those of the former species. — W. J. Beal, Agricultural College, Mich. Errect OF Ick Upon Trees. — In the latter part of March of the present year a heavy fall of freezing rain covered the trees of eastern Nebraska with a coating varying from one-third to one- half an inch in thickness. Every twig, every bud was encased in a thick, transparent, icy envelope, whose weight bent and broke a t number of branches from the trees. There was a notable ifference in the behavior of the different trees under this weight of ice. Trees with branches standing approximately at right angles with their axes fared best, while those with more upright the cottonwood, it was plain that those approaching the exeurrent type of ramification suffered least. Some trees of this type were PLATE IV. re i = Sa X ~a Gs REE X NN Bek i cots ee rtions of separate Poono ok Taiki virginica Willd., to show Pi: 4.

Elms usually bent their branches'until supported on the ground. Maples (Acer dasycarpum Ehrh.) acted very nearly as the Cotton- woods did, some breaking, while others withstood the strain. No hackberries (Celtis occidentalis L.) broke at all, their strong branches with axillary angles of nearly 90° rendering them strong enough to withstand the heaviest weight. White pines (Pinus strobus L.) suffered more than the Scotch and Austrian pines, the latter having (when young) more widely divergent branches than the former. Red Cedars and Balsam Firs trailed their lower branches upon the ground, while those above hung and rested upon those below. An attempt was made to estimate the weight borne by each tree, and the result showed that such ice burdens are very generally over- estimated. By melting the ice from a measured length of a twig, it was easy to estimate the amount of water carried by the tree. It was found that for a fine box elder, twenty-five feet in height, and with a large rounded top fully twenty-five feet in diameter, the total weight did not exceed three hundred pounds. The calcula- tion was carefully revised, because the result seemed too small, but lt was found to be correct. The effects which are so striking are clearly due to the fact that this weight, although so small, is borne as well by the slender twigs as by the larger branches. A weight of a few ounces upon the end of a lon twig produces a much oo bending than many pounds would at its base.— Charles essey. ZOOLOGY.

He does not agree with Ridley and Dendy in their views of the origin of the horn-sponges, but regards this group as having a polyphylitic origin. The Australian Calc- sponge fauna is very rich, while the deep-sea Hexactinellide and Lithistide are wanting. His conclusions regarding the sponges are:—(1) The littoral sponges are widely distributed, about half the species being cosmo- politan ; (2) The most recent and most highly-developed forms rarely occur in the colder waters, and their relative numbers is in proportion to the coldness of the sea; (3) Newer forms follow the older, not only when we go from the deeper to the more littoral zones, but from the poles to the tropics; (4) The lower and older types are more plenty in the cold than in the warmer seas, and are especially rare in Australia; (5) There are a series of forms which are confined to Australia, but there is only a few which are confined to any other region; (6) All the larger genera are cosmopolitan ; (7) The fresh-water sponges are more uniform and more widely- distributed than are the marine sponges. New Enetanp Mepus%.—Dr. J. W. Fewkes presents (Bulletin Mus. Comp. Zool., xiii.) a list of the Medusze which he has studied on the coasts of Maine and Grand Menan. The list embraces fif- teen species and is illustrated by six plates.. A full account is given of Nanomia cara, supplementing the account of Dr. Alexander Agassiz, showing that these forms really possess both sexes united in one colony, and giving an account of the embryos up to the eight-cell stage. The rare Callinema ornata is also figured and escribed.

Seyp tage óf Antelis, 356 General Notes. Muscies oF Moxuuscs.—There are frequently described in molluscs striated muscles, sometimes of a peculiar type. Müller and Keferstein have described them in the heart of Cephalopods and in the pharynx of the Cephalophora ; Blanchard, in the adduc- tors of Pecten, and Paneth, in the fins of Pteropods and Heteropoda. Schwalbe has described in the adductors of the lamellibranchs and elsewhere muscles with a double oblique striation, while, before. - him, Mettenheimer, Wagener and Margo had referred to the same appearance as spiral striation. Lately, Fol (Comptes Rendus, Jan. 23,1888) has investigated the same subject, and concludes that true striated muscles do not exist in any mollusc. All cases reported as such, in reality, consist of smooth fibres, around which fine fibrils are rolled in a spiral manner, this being the case in all the special -instances noted above. The method employed by Paneth (glycerine and nitric acid) produced such contraction that the spiral fibrillee really appeared transverse. of the molluscan muscles are of the smooth type; but these are to be grouped in two sub-divisions— that already mentioned, and that in which the fibrille are straight. The latter are the more abundant. Judging from their distribu- tion, the spiral type are of value where a rapid contraction is needed, THE Primary Groups OF MAIL-CHEEKED FISHES. — recent study of the structural characteristics of the mail-cheeked fishes has led to some interesting and unexpected results. The genus Dactylopterus, which has been almost universally closely associated in the same family with Trigla or Peristedion, an especially with the latter, was found to differ very widely. The relative proportions of the spinous and soft parts of the dorsal fin, to which so much value has been attributed by Dr. Giinther, proves to be of comparatively slight importance. All the families recog- nized by Dr. Günther, except that of the Heterolepidotide, are very unnatural combinations of dissimilar groups; most of those recognized by myself are amply justified by anatomical evidence, but several others must be added to the list. The genius of Cuvier, manifested in the perception of the rela- tions of forms differing so much in superficial characteristics as do the mail-cheeked fishes, is justified by a detailed study of the various constituents of that group. The course of Günther and his fol- lowers in disintegrating it, widely divorcing its constituents, an associating its fragments with dissimilar forms, was a deci edly retrograde step. Nevertheless, although the group is one whose members are genetically connected, the diversities of structure are too great to allow of their retention in one family or even super- family. They must be distributed into four (and ultimately more) superfamilies; those nów determined are the So the ) Cottoidea, the Trigloidea, and the Dactylopteroidea. veral forms Zoology. 357 that have not yet been anatomically investigated represent families— Caracanthide, Platycephalide, Agonide, and Rhamphocottidee—ex- hibiting very peculiar characters, which must be reflected in their skeleton, and their exact relations remain to be ascertained ; prob- ably none belong to any of the superfamilies now established.’ The families hereinafter enumerated appear to be all well entitled to the rank, and are characterized by various anatomical peculiarities. The most closely allied pair, and which perhaps need future con- firmation,are the Hexagrammide and Anoplopomide. All the fami- lies will be diagnosed and, in part, fully described in several memoirs Aaka for publication in the Proceedings of the United tates National Museum, and the anatomical characteristics of the crania will therein be illustrated.

Gill. THE Cocoon or Proroprerus.—Professor Wiedersheim (Anat. Anzeiger) has collected together the various notices that have been written by J. E. Gray, A. D. Bartlett, Krauss, A. Giinther, and . others concerning the structure of the case or “cocoon” of the curious fish Protopterus, and describes the result of his own obser- vations upon the subject. Krauss’s description of the membrane surrounding the fish is substantially correct. It appears to be designed to protect the animal from damage during its eestivation 5 Zoology. 309 but the source of the secretion composing it—whether the skin or a special apparatus—is not yet known. The manner in which the animal lies rolled up within its case is very singular and has not previously been described. The head and anterior part of the y are concealed or roofed over by the broad membrane of the lower lobe of the tail. Our author thinks it probable that the broad tail-fin serves the Protopterus fora purpose unheard o before, viz., as a breathing organ. The part which covers the head has a reddish tint, and it seems likely that it is permeable to air, even if we suppose it is in communication with the breathing-tu piercing the capsule. A Grarn-Eatine Reptite.—Several lizards have been known to eat vegetable substances, among them Uvromastix acanthinus, umeces aldrovandi, Lacerta ocellata and Stellio vulgaris. Johann von Fischer calls attention to the fact that Uromastiz hardwickii, a Bengalese species in his possession, would take no animal food ; but an examination of his excrement disclosed an abundance of starch granules. This led him to place before him various grains—rice, corn, etc.—which he ate with avidity. This isa new feature in reptilian diet. He also afterward ate various insects and drank— a fact which has not been witnessed in its relative, U. acanthinus. The chief food of the latter, lettuce, was neglected by the species in question, but it willingly ate straw and hay.

ZOOLOGICAL NEws.—EcuinopErMs.—The habitat of the star- fish, Echinaster decanus Müller und Troschel, has not been known. Lately it has been dredged of Port Jackson, Australia. ` Professor F. Jeffrey Bell, in an account of the specimens, states that the species is remarkable for the large size of the pore areas, in which there are a large number of respiratory processes, and hence con- cludes that it lives in situations where respiration under ordinary circumstances would be difficult. The brothers Sarasin have a note on the longitudinal muscles and “ Stewart’s organs ” in the Echinothuride, in the Zool. Anzeiger, No. 273. The long muscles are of use in the vermicular move- ments of Asthenosoma. Concerning the function of “ Stewart’s organs,” they have no opinion to offer. Fifty species of Echinoderms, twenty-two Holothurians, thirteen Asteroids, six Ophiuroids, and nine Echini, have been collected at the Andaman Islands by Mr. Booley. Worms.—Mr. F. E. Beddard continues his notes on the earth- worms. In the Zool. Anzeiger, No. 272, he states that the “ mucous gland” described by Perrier in Urochzta “ consists of a tube open- ing on to the exterior by a single orifice and branching distally into a number of tubules, each of which opens into the ccelom by a cili- ated funnel,” these funnels being disposed irregularly, and not metamerically. n another note in the same number he describes briefly the sali- vary glands and capsulogenous glands in Pericheta. The former he regards as homologous ofthe septal glands of other Oligocheetes. The capsulogenous glands, it is hoped, will furnish good characters for the discrimination of the species of this difficult genus. Dr. Frederick Tuckermann notes a specimen of Tenia saginata of unusual size. Only a portion of the worm was obtained, but this consisted of 711 segments, and measured 7.455 metres in length. Comparison with other specimens led to an estimate that the whole worm consisted of about 1060 joints, and a total length of 7.655 metres. According to Mr. R. Moniez, the eysticercus of the Tenebrios does not belong to Tenia nana, but, as is proved by the length and the number of its hooks, to Tenia microstoma, a species parasitic within the mouse. T. nana and T. murina constitute two distinct species, and the latter develops in the intestine of the rat without an intermediate host. . ARACHNIDA.—Duges describes (Bull. Soc. Zool. France, 1888) a - new species of mite, Geckobia oblonga, which occurs, parasitic, upon the lizard, Scoleporus spinosus. The species is noticeable for the elongate organs, of problematical functions, which arise on either side above the base of the rostrum, They have an appendicular Zoology. 361 appearance, are united at their bases, and terminate, each, in a toothed pincer. FisHes.—M. L. Vaillant has recently, in a note upon the com- parative dimensions of young and adult examples of Alopias vulpes, remarked that the size of the young is, among fishes, influenced by that of the parent, which commences to reproduce before its growth is complete. A specimen of A. vulpes, taken at Cette, measured — 4.70 metres in length, and the largest of four foetuses contained within its oviduct had a length of 14 metres. On the other hand, a female fox-shark, 1.17 metres long, also contained foetuses. It is not always that collectors note down the colors of the speci- mens while still alive, and thus the small collection of fishes from the Society Islands and Paumotu, made by Lieut. M. Trigon, omes of value through the sketches accompanying it. M. Vail- lant draws attention, in some prefatory remarks, to the losses incur- red by attaching metal tags to the specimens by means of copper or iron wire instead of by vegetable fibre. Galvanic action is set up, and the scales and bones of the fishes, as well as the wire itself, are destroyed or fall apart. A recent number of the Jzvestia, of the Russian Geographical Society, contains M. N icolsky’s sketch of the fishing on Lake Aral, - which is a valuable contribution to the ichthyology of that lake and of the Lower Arnu-daria. ton of the paired fins of Ceratodus, with observations upon those of the Elasmobranchs. His conclusions are that the characters of the 362 _ General Notes, skeleton of the paired finsareinconstant,some of those of the praxial parameres of the pectorals and the basal mesomere of pectorals and pelvic fins; that a reduced metapterygrum is always present in the pectorals, and may occasionally be traced in the ventrals; and that the basal mesomere of the Ceratodus fin may conceivably have been derived from the metapterygium. The structural features of both paired fins of the Chimeroids are identical, and characterized by the absence of a mesopterygium, and the paired fins of Plagios- tomes and Dipnoans have probably arisen from a type of fin most nearly represented by that of the living Chimeeroids. Prof. T. J. Parker describes and figures, in the Proceedings of the Zoological Society of London, the skeleton, fins, heart, brain, etc., of Carcharodon rondeletii, from specimens taken near Dunedin, New Zealand. A peculiarity in external form, scarcely noticed previously, is the depression of the tail just in front of the caudal fin, so much so that the width is more than double the height. Prof. Parker believes that this flattening, present also in Lamna, gives a combination of horizontal with vertical tail-fin, useful as a means of enabling the fish to rise rapidly from great depths. ° r. Francis Day has lately published a work on British and Irish Salmonide. He regards the different forms of non-migra- tory trout known as Brook trout, Lochleven trout, Crasspuill trout, Estuary trout, Orkney trout, Cornish trout, Great Lake trout, Gillaroo trout, and Swaledale trout, as varieties of one species, and all the species of char as identical with Salmo salvelinus. ReptiLes.—Mr. C. M. Woodford has recently returned from th Solomon Islands with a collection of over two hundred reptiles, which have been examined by Mr. G. A. Boulenger. The fact that this large collection contained but four new forms indicates that the reptilian fauna of these islands is pretty well known. Mr. F. E. Beddard notes the presence of a peritoneal fold in the genus Monitor, separating the lungs from the abdominal viscera, and corresponding to a similar structure in the Crocodilia. Meo G oulenger describes a Leptodactylus, three species of Lygosoma, ops aluensis, and the Batrachia Hyla lutea and Batrachylodes vertebralis, from a collection made in the Solomon Islands by Mr. C. M. Woodford. Two lizards, Varanus niloticus and Chameleon owenii, and the snakes Naia haje and Dendraspis angusticeps, were collected by Mr. Johnston, at a height of 2000 feet on the Cameroons Moun- ins. M. L. Vaillant (Bull. d.1. Soc. Philo. de Paris) has recently described a new species of land-tortoise (Testulo yniphora) from one of the Comoro Isles, or from an islet in their vicinity. The cara- pace of the largest specimen is about fifteen and a half inches long, Zoology. 363 twelve and a half inches wide, and nearly a foot in height.

Daly, at a recent meeting of the Zoological Society of London, gave an account of the caves in Borneo, from which the edible birds’ nests are obtained. Of these, fifteen are known in North Borneo. Most of these are in limestone in the interior, but two are near the coast, and occur in sandstone strata. Mr. H. N. Ridley found a new species of tyrant-bird in his explo- rations of the island of Fernando Norohna. Mr. R. Bowlder Sharpe has described it, under the name Elainea ridleyana. Mr. R. S. Wray has found in the wing of the adult ostrich a ves- tigial structure representing the distal phalanges of digit III (P. Z S, 1887.) Among the thirty-five species of birds collected by Mr. C. Wood- ford, in the Solomon Isles, is a new crow, described by Mr. Ogilvie Grant as Macrocorax woodfordi. Mr. Bowdler Sharpe has described (P. Z. 8., 1887) seven new species of birds, from a collection made by Mr. L. Wray in the mountains of Perak, in the Malay Peninsula. Mr. R. S. Wray contributes to ‘the Proceedings of the Zoo- logical Society of London (1887), an important paper upon the morphology of the wings of birds. MamMAtia.—Dr. Dubois describes a sixth species of Anomalu- rus, under the name A. chrysophenus, in the Bulletin Société Zoolo- gique for January. It is most nearly allied to A. pelii of Tem- minck, and comes from West Africa. The collection of mammals recently made in the Solomon Islands by Mr. Woodford, consisted chiefly of bats.

ENTOMOLOGY.’ ON THE SYNONYMY OF THE APPLE-LEAF CREASER, ORNIX GEMINATELLA (Packard).—Having lately had occasion to study the Tineide infesting apple leaves in Illinois, I have been puzzled over the proper name of a common species which inhabits a tent- shaped mine on the under leaf-surface. Tt is the insect that Mr. . E. Brunn has discussed? as Ornix prunivorella Chambers, but which I believe to be the same as Packard’s Lithocolletis gemina- tella. The agreement of my specimens of the various stages of the insect, with the descriptions of these species as given by Packard, ambers and Brunn, led to a careful examination of the literature treating of the two species, the results of which I briefly summa-. rize below. The subject is more fully discussed in a paper to be sta ai in the Fifteenth Report of the State Entomologist of inois. The various stages of Lithocolletis geminatella were described and figured by Dr. Packard in 1869.3 The description of the moth is rather brief, but the figure is excellent. The larva is said to be of a pale livid reddish color, with the head and cervical shield black ; and to mine the leaves of apple and pear. Two years later Chambers published‘ an article on the described species of Lithocolletis, in which he surmises that geminatella does not properly belong to this genus. In the Canadian Entomologist for March, 1873, Mr. Chambers published a description of Ornix prunivorella, stating that the larva mines the leaves of the apple and wild cherry, and giving a brie account of its habits. In an article on the Food-plants of the Tineina, published some- what later Mr. Chambers mentions this species as feeding on wild cherry, but strangely enough omits it from the list of those feeding upon apple, although in connection with the original description he remarks that “the larva mines the leaves of apple trees.” In this list Lithocolletis geminatella is not mentioned. 1882 Lord Walsingham published some “Notes on the Tineidæ of North America.” This paper was the result of a study 1 This department is edited by Prof. J.

On page 194, in speaking > of certain of these specimens, he says :— “I think these may be Ornix prunivorella Chamb., although that author does not record that the larva of that species feeds on: apple or pear. These specimens are not in good condition, and it is impossible in so difficult a genus as Ornia to be quite certain to what species they belong. i “ They are the types of Lithocolletis geminatella Packard, accòrd- ing to the label attached to the second specimen, but they undoubt-. edly belong to the genus Ornix.” From the statement just quoted, that Chambers doés not record) the apple-feeding habits of O. prunivorella it seems evident that Lord Walsingham had been misled by the omission in the list of food-plants noted above. accounted for on the supposition that Dr. Packard’s specimen was. immature, for, as Mr, Brunn has remarked, these larve are flesh- colored when young.

It should be ~ read by all peones in the biological side of entomology that 1 Psyche, Vol. V., pp. 3-12. 366 General Notes, have not occasion to keep track of the literature concerning the minute organisms that cause disease. A few of the more general oints can be stated here. Contagious disease, wherever it has been traced to its origin, has proved to be the phenomenon of para- sitism. This address is limited to a discussion of epidemics caused by Fungus or Protozoan parasites. s Of the Protozoan diseases of insects, pebrin of the silkworm is the best known example. There has been much discussion regarding the position of this parasite; butthere can be no longer a reasonabledoubt of its animal nature, or of its agreement in general characters with those forms now commonly included under the head Sporozoa, a parasitic-subdivision of the Protozoa of which Gregarina is per- haps the best known type. The life history of this parasite is very simple, and may be thus briefly summariz he minute oval spores, colorless, highly refractile, homogeneous in appearance, 4 y long by 2 u wide, when swallowed with the food, penetrate in some way unexplained the cuticle of the alimen- tary canal, and, in the cells of the epithelium, open at one end an emit their contents, each in the form of an ameeboid speck of protoplasm. This grows to a spherical body, and, by a process of internal segmentation common to the Sporozoa, is soon conve into a mass of spores, each like the original. These spores every- where undergo a like development, and load all of the tissues with their products, slowly and gradually arresting all of the functions of life. Their vitality is temporary — Pasteur’s experiments showing that they will not germinate five weeks after drying out — and the disease is consequently maintained only by virtue of its hereditary character. Other forms of Microsporidia have been found in at least ten species of insects enumerated by Forbes. : Although pebrine, and presumably other diseases of this nature, can be conveyed to healthy insects by treating their food with the dejections of affected individuals, the economic application of these diseases is limited to artificial measures for developing and acceler- ating them wherever they may be found, and to the transfer of them from one species to another. For there is not the slightest probability that the Sporozoa can be artificially cultivated outside of the bodies of the animals that they infest. The notable fungous diseases of insects are readily divisable into two principal groups: Schizomycoses, produced by Bacteria, and Hyphomycoses, due to Fungi that form a more or less evident mycelium of cylindrical threads (Hyphomycetes and Pyrenomycetes). These are roughly distinguishable in two important particulars: (1) The bacteria invade the body from within, by way of the alimentary canal; and the thread fungi penetrate from without through the skin or spiracles ; (2) Death from a schizomycosis 18 followed by rapid decay, which soon reduces the tissues to a putr Entomology. 367 fluid; while after death from a hyphomycosis the often flaccid body hardens and mummifies without decay, usually swelling to more than its usual size, and frequently becoming covered with a flour-like efflorescence of spores or spore-like bodies. These last characters distinguish the hyphomycoses from the _pébrine, — the body mummifying in the latter, but shriveling at the same time and never covering itself with spores, unless with those of a common mould of post mortem development. Further, the pébrine mummy contains only the minute oval spores of the parasite, while that of a hyphomycosis contains either a mass of mycelial threads or large thick-walled, spherical spores, — the lasting spores of the Hntomophthora, or, possibly, both spores and mycelium together, Examples of Schizomycoses, diseases produced by bacteria, are and fi Jlacherie of the silkworm and foul brood of bee larvæ.

The last topic is. of especial Interest at this time as bearing on the separation, proposed by Brauer, of insects into two groups of equivalent rank, the Apterygo- genea and the Pterygogenea, the former group containing only the Thysannra, the latter, all other insects. Professor Grassi was unable to discover in the musculature of Thysanura any indication of the previous existence of wings, thus confirming Brauer’s view that these insects were “ originally wingless,” instead of, as in the case of wingless forms in the higher orders, being descended from Winged ancestors.

Poulton, in a brief communication to the Royal Society, announces the discovery of the germs of true calcified teeth in the young of the Duck-bi?l, of 8.3 centimetres in length. The sections had been prepared by Professor W. N. Parker for Dr. W. K. Parker, who very generously placed them at the dis- posal of Mr. Poulton, and also urged the latter to publish the account of his discovery, offering, in addition, still other materials, not only of Ornithorhynchus, but also of Echidna. Dr. Parker had laid the sections in question aside for a time (owing to the pressure of other work), to eventually make use of them for the purpose of studying the skull, when Mr. Poulton borrowed the preparations for the pur- pose of continuing his studies on epidermic structures—with the result announced; and under the circumstances his association with this discovery is, therefore, purely accidental ;—yet every true naturalist will appreciate the rare generosity of spirit which Dr. Parker has shown in allowing the independent publication of the results. Tooth-germs, or, rather, young not-yet-erupted teeth, were found in both jaws; and they were found in such a position as to indicate that they probably represent some part of the molar series in the higher mammals, Examining the sections from the front backwards, the first tooth appeared a little behind the anterior margin of the epithelial elevation, which seems to represent the developing horny plate, which, in the adult, is the functional representative of true calcified teeth. The teeth seem to form a tolerably straight line, extending internally to the horny plates, and passing considerably further backwards than the latter. Owing to imperfections in this part of some of the sections, the author could not determine the exact number of teeth with accuracy ; but they appear to be five or six In number on each side. The most anterior tooth-germ is different 0 character from the others, and is apparently separated from them by an interval which is longer than in other cases.

Embryology. 369 distinct. No enamel is formed from them at this stage, except, probably, in the case of the most anterior tooth. The dentine-germ was found quite normal in appearance; the depressed, superiorly conical pulp-mass resembles that seen in other Mammalia, and, as in some other forms, this is to some extent embraced around the sides and below by the in-curved lower edges of the dome-shaped enamel organ, which, as in other forms, is superimposed upon the pulp. Dentinal tubules and odontoblasts can be made out in the vicinity of the apex of the pulp-mass. ere can be little doubt that these structures are characteristic mammalian teeth, as supposed by their discoverer. Hertwig’s researches serve to show that mammalian teeth ‘are probably in a more ancestral condition than any other organ by the ancestors—and yet existing Prototheria were not known to possess them. Their occurrence in Ornithorhynchus, therefore, supplies the step just where it is wanted ; and the fact that they are practicall identical with the young teeth of higher mammals is a further indi- cation of the ancestral nature of these structures; for other higher mammalian features represented in the Prototheria are profoundly modified in the latter. Mr. Poulton, in conclusion, announces his intention of tracing the further fate of the teeth of Ornithorhynchus in later stages, for which purpose Dr, Parker has also placed additional materials at his disposal. THE ECTOBLASTIC ORIGIN oF THE WoLFFIAN Duct IN CHE- LoNIA.'—In a note with the above title, K. Mitsukuri, of Tokio, Japan, gives a short account of his researches upon the develop- ment of the segmental ducts of Trionyx japonica (Schleg.) and Emys pi flotin (Gray). The author has found stages which show that the olffian duct arises from cells proliferated from the ectoblast, just opposite the region of the intermediate cell-mass. As described by others in other forms, these ducts in Chelonians are found by Mitsukuri to develop from before backwards. ti Aa OF THE WOLFFIAN DUCT IN LacERTILIANS.—Inves- gations upon the development of Lacerta agilis, L. lis, and . viridis by J. von Perenyi? confirms and extends his obser- ` Vations upon the ectoblastic origin of the segmental ducts in this and other forms.

Haacke figures and describes the temporary marsupium of Echidna, and reasserts his claim to the priority of the discovery of the oviparity of the Monotremata. The conclusion is reached that the glands sub- serving a mammary function in these creatures are developed from sudoriparous glands, while in other mammals the mammary organs have been developed from sebaceous glands. Two apparently care- fully-drawn figures of this pouch are given, which disappears after the single ovum is hatched. is pouch is not to be confounded with that described by Gegenbaur and Owen as occurring in this animal, PHYSIOLOGY.” DOES THE VOLUME OF A MuscLE CHANGE During ITs CON- TRACTION ?—It has long been a disputed point whether or not the bulk of a muscle alters during its contraction. As far back as the middle of the seventeenth century it was the subject of investiga- tion by Glisson, Borelli, Swammerdam and others, but their meth- ods allowed of errors so great as to make their results nearly worth- less. The first to observe by a fairly trustworthy method that the volume of a muscle is slightly lessened during contraction was Erman, about 1812. Erman’s method consisted in placing the muscle in a cylinder filled with water, and, during contraction of the muscle, observing the level of the water in a narrow capillary tube connected with e vessel. With every stimulation of the muscle Erman noted a slight fall of the fluid in the capillary. Some time after this, Johannes Miiller suggested that the sinking of the level observed by Erman was caused, not by the diminution in bulk of the muscle itself, but by the compression of the air in the spaces between the fibres. Erman’s experiments were thereupon repeated by Marchand and Ed. Weber who eliminated this possible source of error by killing the animals under water. Nevertheless they still observed a fall of the water in the capillary, precisely as Erman had done before them. - In more recent times Kühne has reinvestigated the question, and employed a new method, dependent on the change in specific grav- _ ity which must result from any change in volume. By this method Kühne reached negative conclusions, for he could observe no sink- ing of the araometer when the muscle attached to it was thrown into tetanus. 1 Bi 4 att, VIII, No. 1, ‘ : ; silo, nea I perea ak of Technology, Boston, to whom communications, books for review etc., should be sent. Physiology. 371 On the other hand, Valentin, by the use of the balance, observed an increase in weight of about y4,, during tetanus. Other observers have obtained results quite as contradictory, and it seems almost as if every investigator came to conclusions differ- ing from those reached by his immediate predecessors. All the while, however, the balance of evidence has appeared to be on the side of those who claimed that there was a slight decrease in the volume of the contracting muscle. Most of the recent text-books state it as probable that there is this minute diminution in volume. ere has recently been published an important paper on the subject by Professor J. R. Ewald,! who has repeated, as closely as possible, the experiments of Erman, Marchand, Weber and Valen- tin. Ewald regards Erman’s method as by far the most delicate, if conducted in the right way and under favorable conditions. He then suggests that Erman and ‘his successors have erred in some critical respects in the course of their experimental work. Ewald accordingly altered Erman’s method in the following manner: Into a glass flask two platinum wires are melted just above the base, so that they are diametrically opposite, and reach some millimetres down into the vessel. On the outside they form small hooks upon which can be hung the wires leading to an induc- tion machine. The glass stopper of the flask is hollow and ends in a tube which is drawn out so as to be capillary. The animal is killed under water, and the muscle without the nerve freed from the body. The flask, stopper and capillary tube to sink with great swiftness, owing to the expansion of the glass. A drop of ether evaporated on a lass anion the reverse effect >the meniscus rapidly rises. If the strength of the current be d so that bubbles of gas begin to be formed on the elec- trodes, it will then be seen whether a very slight increase of vol- ume in the interior of the flask will perceptibly change the posi- 1 Pe Md (Pfliiger’s) fiir die gesammte Physiologie (1887), Bd. xli., 8. 372 General Notes. tion of the meniscus in the capillary. Ewald did this, and with a duration of the current so short that the bubbles on the electrodes became just visible, he saw the meniscus bound across the whole field of vision. By calculations based on the bore of the capillary and the magnifying power of the microscope, he found that a loss . of a ten-thousandth of a cubic millimeter could not have escaped notice. The author used also a second method, somewhat similar to that employed by Kiihne, and obtained the same decisive negative result. He next repeated the experiments of Valentin, which were based on the use of a very delicate balance. Here, too, he states that, with proper precautions for securing the accuracy of the apparatus, there is in no case the slightest movement of the inter. Ewald then gives an extended account of his repetition of the experiments of Erman, Marchand and Weber. He suggests a very probable source of error in the failure of those observers to fix the stopper firmly into the vessel used in the experiments. When this and other details were attended to, he found that he could detect with the microscope no change in the level of the meniscus in the capillary tube. Ewald, then, has repeated the experiments of preceding obser- vers, has devised several new methods of greater delicacy than any heretofore used, and has arrived always at the same conclusion— that in no case does a muscle change in volume during contraction. Moreover, he has shown in addition that there exist very probable sources of error in the methods used by those investigators who have obtained positive results. Under such circumstances we can ly refrain from considering the question as settled beyond rea- sonable doubt.—E. O. Jordan (Boston). ORGANIZATION ‘OF THE AMERICAN PHYSIOLOGICAL SOCIETY itch, of n, clerk. A constitution was adopted and a formal meeting, the first of the American Physiological Society, followed. Officers were chosen as follows: President, H. P. Bow- ditch ; Secretary and Treasurer, H. N. Martin, of Baltimore. These officers, together with Professors J. G. Curtis of New York, H. C. Wood of Philadelphia, and H. Sewall of Ann Arbor constitute the “Council” of the society. The constitution affirms that the society “ is instituted to promote the advance of physiology, and to facili- tate personal intercourse between American physiologists.” The regular annual meetings are to be held, during the winter holidays, Physiology. 373 at places fixed by the Council; and any resident of North America otherwise eligible (as described beyond) may be elected an Ordinary member. There were present, in fact, representatives from places as far apart as Montreal, Ann Arbor, Baltimore and Boston, The Institutions represented at the meeting included Harvard Univer- sity, Yale University, Johns Hopkins University, The University of Pennsylvania, The University of Michigan, McGill University, The (Columbia) College of Physicians and Surgeons of New York, the Massachusetts Institute of Technology and the Medical Staff of the U. S. Navy. The present members of the society are as follows: H. G. Beyer, U.S. Navy; H. P. Bowditch, Harvard University ; H. C. Chap- man, Philadelphia; R. H. Chittenden, Yale University; J. G.

The name “ American,” moreover, seems here better justified by the geographical limit adopted than is usual in the case of such organizations. THE PLACE or BACTERIOLOGY IN MODERN Scrence.—The preceding paragraphs may serve to show to which hemisphere of the great biological globe this new science belongs. -For if bacte- riology has a place anywhere, it is surely in experimental pathology and experimental hygiene. Botanically speaking, bacteria are of no unusual interest on the morphological side. They are too small and too undifferentiated to yield great morphological harvests, at least with our present means of study. But from the physiological side they are just now with- out a parallel among living things, both in interest and in import- ance. The deeds which they do, the marvellous effects which they produce, are out of all proportion to their apparent anatomy. Some of the steps in the progress of this new physiological science will hereafter noted in this department, and workers are cordially invited to send to its editor brief notes, or items of interesting news in bacteriology. ARCHAZOLOGY AND ANTHROPOLOGY.’ At the late meeting of the Society of Anthropology, Washington, D. C., interesting papers were read,—one by Mr. H. M. Reynolds on the subject of Algonquin metal-smiths. The writer treated with - care the important question whether the Indians were acquainted with the art of smelting copper. He argued that the working of the copper-mines of Lake Superior was not of such high antiquity as has been supposed, and may have been continued until compara- tively modern Indian times. “The other paper was by Mr. Jeremiah Curtin, on Moqui myths. 1 This department is edited by Thomas Wilson, Esq., Smithsonian In- — stitution, Washington, D.C.

Patent Office of Washington, is interested in the various inventions of time-keeping, and has read a paper before the Anthropological Society in Washington on time- keeping in Greece and Rome. He is pursuing the subject, and invites correspondence and assistance. He proposes to trace the existence and development of the notion of time-keeping among savage and barbarous races; also the history of time-keeping from its dawn down to the middle ages. Spurious ĪNDIAN ARROWHEADS.—An enterprising individual in the vicinity of Orwigsburg, Pa., has recently put on the market well-made arrowheads of curious design, against which it may be well to warn collectors. These relics, instead of being made directly from flakes, are genuine arrowheads rechipped, thus increasing the depth of the notches, sometimes the base of the shaft, and usually allowing so much of the lateral edges of the anterior portion of the arrowhead as to make it resemble at the point a small lozenge or diamond attached to the original base by a stem. One specimen which had been broken across was retouched, so as to permit the original base to remain, but presented two points, the intervening The National Geographic Society has been organized under excellent auspices.

General Greely spoke for the climatic repre- Sentation ; Conan Bartlett, foe the den and its shore; Profes- sor Ward, for Paleo-Botany ; Dr. Merriam, the distribution of bird- life. Mr. Henshaw’s subject was of greater interest to anthropol- ogy. He showed the distribution of Indian yon in North America at the dawn of its history. He presented a map made at the Bureau of Ethnology, the result of eleven years of labor of him- — self and Major Powell. This map covers the entire area of North 376 General Notes. America, showing each Indian language belonging thereto, with all their sub-divisions, separations, and migrations—so far as possible to be discovered at this earliest epoch. This work is as interesting as it is important, and its authors are to be congratulated upon their success. It is to be hoped that Major Powell will have the map published for immediate distribution without awaiting the long tedium of the Public Printer, whose office is now being investigated by a committee of Congress. ; The appointment of Mr. Justice Lamar to a seat upon the bench of the Supreme Court n the United States marks an era in the his- tory of our country. ery one recognizes this as true politically ; but I speak of it anthropologieally Mr. Justice Lamar is said to be what is called in French “visuaire”—that is, mental impressions stands the thought best by seeing the pe page, while the “audi- . taire” receives his best impression by hearing. In the Supreme Court the arguments of counsel are, of course, oral; and how Mr. ustice Lamar, with this peculiarity of mental organization, will adapt himself to his new position remains to be seen These differences in human mental organization are well known to anthropologists.

Whether in the Senate, in the House of Re gag epii at the bar, or on the stump, asan orator he was ead i by few and excelled by none. He thought well and clearly when on his feet. Amid all his wit and humor he was a most consummate lcin, and could carry on the thread of an abstruse argument and support it by most cogent rea- soning. But as Governor or cabinet officer, his state papers were not above the ordinary. Taking’ a pen in his hand, his thoughts seemed to scatter, and his writing was common lace. Addressing the multitude, his thoughts seemed to crystallize into most beauti- ful forms, and he spake as one inspired. e causes of these differ- ences have never been discovered. They are suggested aş a theme for the student—biologist or anthropologist—as instructive as they are interesting. “T/Homme Avant L’Historre.”—This is a new book on subject of prehistoric man, written by M. Ch. Debierre, mir r in Paris. The author is a professor in the faculty of medicine at Lyons, France. M. Cartailhac, while giving it credit for muc that is useful and interesting, criticises somewhat severely the mass of errors which he finds therein. Thus, page 141: “There are Archeology and Anthropology. 377 stations where the debris of human work united the two ages (paleolithic and neolithic), and testify the passage from one to the other.” i nothing to prove this.” Of the neolithic age the author says, “‘ The reindeer was disap- pearing from the country (southern France).” He should have said, “ had already disappeared.” gain, “some of the dolmens of France are known under the name of menhirs.” He should have said, “some of the megaliths,” e : “ The men of the neolithic age immolated without doubt human ae to their gods,” ete.

Cartailhac says the last word should be Africa, for we do not know of true dolmens in America. And, “it is nearly certain that the construction of dolmens was perpetuated in England and in France until near the eighth cen- tury of our era.” M.

He was the founder of the journal Materiaux pour L’ Histoire Prim- ive et Naturelle De L’ Homme, now conducted by Cartailhac and Chantre. In 1883 he established the journal Z Homme, which he has carried on with credit to himself and profit to his readers.

The cause of cessation of the journal is not from failure of any kind, but from greater devotion to science. These gentlemen, indi- vidually and collectively, are the founders and organizers of the Bibliothique des Sciences Contemporaines, of the Dictionaire des Sei- ences Anthropologiques, and of the Bibliothique Anthropologique, and they have decided to suspend, the journal that they may devote their entire time to the two libraries and the dictionary. he Prehistoric Anthropologists of the United States send their wishes of fraternal good fellowship. The enquiry started by the Smithsonian Institution in regard to the existence and geographic distribution of the so-called “rude and unfinished implements of the paleolithic type,” is one of high importance in the study of American Prehistoric Anthropology- Responses have been received from thirty States and Territories, the implements already noted amount to between six and seven thousand, and their distribution extends nearly all over the United States. Several hundred implements have been sent to the Institu- tion, some of which do not belong to any paleolithic age, but many of them do. None seem to have been found in the mounds. The implements themselves are of no merchantable value. The Institution desires them principally for verification, to see that they are really paleolithic implements, and not the leaf-shaped spear and arrow heads so common; also to know their geographic distribu- tion. It wishes to know, approximately, how many have been found within a given district or State, if there has been anything peculiar in their finding, position or locality, especially with refer- ence to river gravel drift. e present examination is tentative and does not attempt to deal with the antiquity of this paleolithic age, but only to discover if there was such an age in America, and, if so, whether i had any extended existence. The attention of the average relic collector has never been called to this sort of specimen, and they have not usually been gathered. It will be something gained for science, to know how these implements are distributed over the Unit States, and especially their relationship to the glacial moraines. Microscopy. 379 MICROSCOPY.! A New METHOD FOR THE MicroscopicaL STUDY OF THE Buioop.*—The methods hitherto employed in preparing the blood for microscopical examination have aimed either at the production of fresh or of dry preparations. Preparations of the first class are not permanent, and those of the second class never exhibit the mor- phological elements intact. Dr. Biondi has worked out a method which combines the advantages, and is free from the defects, of previous methods. The problem was to find the means of perfect ation, preservation, imbedding, and mounting—in other words, a method by which the blood could be treated as a solid tissue. The method is equally useful in the study of other organic fluids, and has been successfully employed in tracing the changes that take place in the maturation of the spermatozoa. It may doubtless be sity advantage in the study of Infusoria, as suggested by iondi. The point of chief interest in Biondi’s method is the use of agar as an imbedding material. Agar is a vegetable gelatine, obtained from Gracilaria lichenoides and Gigartina speciosa, and has already been successfully employed for some time by Koch in bacteriologi- cal investigations. Among the different sorts of agar, the colum- nar form Saulen-Agar) is considered the best. A perfectly trans- parent solution is required, in the preparation of which great care must be taken. This may be accomplished in the following man- ner: Place two parts of agar in 100 parts of distilled water, leav- ing 1t to soften for twenty-four hours at the ordinary room temper- ature ; then heat to boiling on the sand-bath until the agar is all dissolved. The evaporation of the water may be checked by clos- ing the flask with a cork provided with a long glass tube. Add carbonate of sodium to the point of weak alkaline reaction, and for an hour in a steam-apparatus. Pour the solution into long, slender test-tubes, and leave from twelve to twenty-four ours at a temperature of 50° to 60°C. The solution separates into two layers, the upper of which is quite clear, and this layer alone can be used for imbedding purposes. But clarification must be carried still farther before it is fit for use. The clear put egg added, the mixture shaken up several times in the course of ten minutes, boiled for an hour in the steam-apparatus, and then 7 Bi D. Biondi. Neue Methode der mikroskopischen Untersuchung des utes. Arch. f. mik. Anat., xxxi., 1, p. 103, Dec., 1887. 380 General Notes. red. The reaction should then be tested, and, if necessary, carbonate of sodium added until the solution is neutralized. Exact neutralization is necessary, in view of the staining fluid to be employed. It is important that the mass should be kept sterile up to the moment of using, as otherwise a large number of micro-organisms may develop in it, and render it worthless for the finer uses. It is advisable, therefore, to keep the mass in test-tubes, limiting the quantity placed in each to the probable requirements of a single imbedding operation. For a single preparation of the blood five ccm. of the mass is sufficient. The test-tubes should be cleansed with hydrochloric acid and then washed with distilled water. After receiving the agar solution, the tubes are closed with cotton, and then sterilized in the steam-apparatus for half an hour daily on three successive days. As the preparation of the agar mass is somewhat complicated, much time and trouble may be saved by turning this work over to some apothecary. König of Berlin (Dorotheenstrasse, 29) furnishes the mass prepared as above described. The best medium of fixation for the elements of blood is a 2 per cent. solution of osmic acid. If a drop of blood from the frog be examined in this medium under the microscope, it will be seen that _ both the red and the white corpuscles are perfectly preserved in form and structure. The red corpuscles become a little paler than in the living condition, and are slightly browned. The corpuscles of mammalian blood are isolated and seen to greater advantage than in any other medium of fixation. As it is important that the acid should be perfectly clear and free from all impurities, it is well to filter before using. Method of Procedure.—1. By the aid of a clean pipette, take a little blood from the heart of a frog, and allow two drops to fall into 5 ccm, of osmic acid (2 per cent.). Shake a little—the sooner the better—in order to separate the elements and scatter them through the whole body of the acid. After standing awhile, the blood corpuscles will be found at the bottom of the tube, the deeper layer being formed mainly of red corpuscles, which sink first by virtue of their greater specific gravity. Exposure, one to twenty- four hours. ‘ 2. The process of fixation completed, 4 to 5 drops of the mix- ture of blood and osmic acid are allowed to fall from a pipette into the melted agar, which is kept fluid at a temperature of 35 to 37°C. By rotating the test-tube, the blood corpuscles are dis- tributed through the agar, and then the whole is poured into & aper box, as in the ordinary paraffine method of imbedding. Within a few minutes the mass stiffens, and may be removed from the box to 85 per cent. alcohol for hardening. In three to SIX Microscopy. ast days the mass is hard enough for sectioning, and may be inclosed in elder pith and cut with the microtome. ner sections are required than can be obtained in this way, the agar block may be imbedded in paraffine in the following manner : e block is to be transferred from the 85 per cent. alcohol to bergamot oil (twenty-four hours), then direct to soft paraffine kept at a temperature of 45°C. After one to two hours, the imbedding process may be completed in the usual way. As the agar is saturated with paraffine, very fine sections may be obtained ; and these may be freed from paraffine with the usual sol- vents, and then stained. 4. Sections may be clarified, preparatory to mounting, in bal- sam or damar, in clove oil, origanum oil, bergamot oil, creosote, nase Xylol alone should not be used, as it causes the sections to curl. Boverrs METHOD oF PREPARING THE Eces OF ASCARIS. MEGALOCEPHALA.'—1, The egg-sacks are plunged for a few sec- onds into boiling absolute alcohol which contains 1 per cent. glacial acetic acid.? The eggs are thus killed instantly, and at the same time the egg-membrane is rendered penetrable to the reagents..

If the egg- sacks are removed from alcohol to a mixture of glycerine (1 part) and absolute alcohol (3 parts), and then allowed to stand until the alcohol has evaporated, the eggs do not shrink. It will be found, however, that the eggs are not all equally well preserved with the cold mixture, owing probably to individual differences in the con- stitution of the membranes, some being more, others less, perme- able to the fixing reagent. AN INEXPENSIVE SECTION-SMOOTHER.—The cut shows a device for preventing the curling of paraffine sections, which is extremely simple and easily made. After cutting off the head and point of an ordinary brass pin, fix it parallel to the edge of the knife by pressing its ends into two small pellets of beeswax. The pro elevation is easily determined by testing on the waste paraiiine before the object is reached. The pin can only be used with the transverse knife. With the knife set obliquely, a piece of drawn wire will serve the same purpose.—H. C. Bumpus. TABLETS FOR ANATOMICAL PREPARATIONS.—Lhe following information respecting the materials used for mounting tablets 1m the Museum of Comparative Zoology has been furnished by Pro- fessor E. L. Mark :— For dry objects, various materials haye been used at different times: (1) Glass painted on one side; (2) plaster of Paris slabs, white or colored ; (3) pasteboard ; (4) wood, thin layers glued, with grain running at right angles; (5) slate; (6) cement, The last is worthless. Slate is now preferred. Samuel Garman was the first to use the plaster tablets for alco- holic preparations. In the Annual Report of the Curator for 1877-8, p. 25, Mr. Garman says: “It is found that by mounting the majority of the Sauria and Batrachia on plaster tablets in jars of alcohol their value for purposes of exhibition is greatly enhanced. This takes considerable labor ; but once mounted, they will need no further attention for a long period.” Garman used these tablets in his own room as early as 1875, but they were not introduced into the exhibition rooms until 1877.

MAY, 1888. No. 2567 GUATEMALA FORESTS. BY MILES ROCK. : a general view over the surface of Guatemala we observe a great difference in the character of the vegetable covering. Little of this difference can be due to change in latitude, as the whole Republic lies within the parallels of 13° 44’ and 17° 49’, or extends only about 4 degreees north and south. In longitude, it lies between 78° 8’ and 92° 10’ west of Greenwich, or extends also 4° east and west. Roughly it is in the form of a square, of which these dimensions of 4° are the diagonals. This country is the northwestern one of the five Central American republics, and covers about one-fourth of their entire area, and is about as large as the State of Pennsylvania, 43,000 square miles, but has hardly one-third the number of inhabitants—say one and one-third millions. What, then, are the causes of the plant diversity? They are, undoubtedly, Ist, elevation above sea level; 2d, meteorological influence of topographical features on climate; and 3d, influence of the ancient inhabitants. The first I take to be the most important cause. We have first the hot climate of the coasts, extending from sea-level to altitudes of 3000 feet, and including (a) The Pacific Coast plain, some 40 miles wide and 135 ong, covering 4500 square miles. 2 (6) The Caribbean Sea Coast plain, some 60 by 20 miles, including the valleys of the rivers Sarstun, Dulce, Polichie, Matagua and Zacapa, and Lake Yzabal, or Golfo Dulce, covering 3200 Square miles, 386 Guatemala Forests. (c) The Gulf region, or part of the great plain entering north- ward from the Sierra Madre, or Cuchumatanes Mountains to the Gulf of Mexico, about 150 miles square, including (1) the basin of the river Neumacinta and its four great affluents, the rivers San Pedro, Lacantun, Chixoy and Pasion, and the narrow valleys of their upper branches, covering some 16,000 square miles; (2) the valleys of the Lagartero and Salegná rivers, 250 square miles; and (3) the valley of the Cuilco River, 50 square miles, the last three rivers being the upper affluents of the Chiapas River, all these regions together making 24,000 square miles of tierra caliente, or more than one-half the entire country. Secondly: A great mountain system running nearly east and west from the Isthmus of Tehuantepec to the Gulf of Honduras occupies the middle of Guatemala between the Pacific and the Gulf plains, in a succession of axes of elevation, vaults and escarp- ments, overlapping or arranged en echelon. In some ten places these mountains attain elevations of 10,000 to 12,000 feet, and elevations 8000 to 9000 feet are numerous. Between these are the many deep erosion valleys, pre-tertiary, which, in the eastern and northern parts of the country, are in the low, hot lands, but in the western and southern parts are filled in with volcanic debris, some trachyte, but mostly ashes, forming extensive and curiously level plains, surrounded by high mountains. These ash plains are from 5000 to 7000 feet above the sea, and form the larger part of the temperate region, or tierra templada, and are the sites of most of the cities and large towns, the seat of most of the population, and mostly cleared and cultivated, now and since remote times, aS shown by ancient remains. These plains are often traversed by impassable barrancos, or ravines with vertical sides eroded through the ash beds since Pliocene times, by small swift rivers, often to depths of 300 or 400 feet. The temperate regions, from 3000 to 9000 feet above the sea, cover about 15,000 square miles, or one-third of the whole surface of the Republic. | Thirdly: We have the remaining one-tenth of the country, OF 4000 square miles, rising above 9000 feet, and in at least two table lands, those of Ixchignan and Chémal, extensive table lands at 11,000 and 11,500 feet, and which are traversed by ridges 1000 feet higher, and finally, there are six volcanic cones attaming — . from 13,000 to 14,000 feet elevation. Guatemala Forests. 387 I have one comment more to make on the face of the country to complete the view, as the matter is usually misunderstood. The twelve or more volcanoes of Guatemala, of which only two show a slight activity, do not form the culminating points of its moun- tain masses, but are seated on the southern slopes, facing the Pacific, shooting up in beautiful symmetrical cones, with straight slopes almost from the sea-level to the point, looming up, viewed from the Pacific, in solitary grandeur, 3000 feet above the lofty sierras behind them. It is one of the great and inspiring sights of the world to thus see close together the three cones of Agua, Fuego and Acatenango, and the Spaniards could not help but place them on the escutcheon of Guatemala as the symbol of this beautiful land. Let us begin at the top of one of these towering, awe-inspiring volcanoes, 14,000 feet above the sea, as Agna, or Tajumulco or Tacaná, and take a general view of the vegetation on our way down to the sea-level. On Tajumulco I spent two days and on Tacan4 eight, to make observations. It was bitterly cold, day and night, reaching 8° F. above zero. The piercing winds blew at times so one could hardly stand up. Large lava stones were piled against the tripod to keep the theodolite from falling over. Hail storms, with terrific lightning and crashing thunder enveloped us. Owing to rarity of air some of the people became sick and had to be sent down. The volcano was extinct (Tajumulco), but several acres of calcined and crumbling rock, and fissures and holes lined with sulphur crystals and incrustations show that not many years ago it burned. On a part of the crater rim were stuck many _€rosses and notched sticks where the Indians come to perform ‘their ancient religious rites. On Tacaná two Chinams (priests) came up and performed a sacrificial rite with a turkey in my presence after I convinced them that I was from another country and would not betray them, for such rites are forbidden. The view extended over the coast plain and many miles over the Pacific to an indistinguishable horizon, where sea and sky blended ; but at sunset one could see where it came, apparently up in the sky. Round about the crater was only sterile desolation, but on descending one soon sees dry grasses, low weedy herbs and stunted Pines and cedars. From 500 to 1000 feet below begin pine forests that extend down to 9090 feet above sea-level. There are * 388 Guatemala Forests. also other trees and shrubs and flowers, the last mostly at the top of precipices, the sides of waterfalls, or wherever the sun can get to the ground. In tropical woods there is not such a profusion of beautiful flowers as in the colder climates; they are too meek and lowly, can get no sun, and are choked out. I have noticed that where trees can get no hold, as on precipices, the rocky banks of rivers, or on narrow promontories jutting into lakes, a great variety of flowers occur ; also in abandoned mountain meadows, where the ancient people cleared the forests away, I have noticed ranunculi, violets, geraniums, fuchsias, begonias, composite, lilies, hortleb y,a utilon malvas, the wild dahlia, and a host of others.? This general shut- ting out of the sun from the ground accounts not only for the lack of wild flowers, but also for the striking abundance of twining and climbing plants. On the higher volcanic slopes are many vines, and among others a blackberry and a tomato that go straight up to the tops of the highest trees before they branch out and spread their leaves to the sun. The way to gather berries of both is to cut down the trees, and when a tree falle the Indians run to where the tree-tops land, to get the berries. At places where large wet surfaces of lava have no covering of soil, they are carpeted over with thick beds of mosses and ferns. In descending the volcano Tacan4, when I first came to such an open place without knowing its character, I began to slide with the green carpet, and, there being no bushes to take hold of, kept on at a dangerous pace until a fallen trunk stopped the avalanche. The trade winds from the Caribbean Sea bring such abundance of - moisture that all summits and slopes exposed to them are inces- santly enveloped in mists, and the woods are dripping as with rain. These are also the regions of heaviest rainfall during the rainy season. Owing to this excessive moisture one finds the great tree- fern growing at exceptional altitudes, at 9000 feet and over, above the sea. They attain a height of twenty to thirty feet, and a diame- ter of trunk of even one foot, and occur in greatest abundance on the north slopes of the volcano Tacan4. From 11,000 to 8000 feet is truly the forest region, characterized by great variety and heavy growth. There are many hard woods, of 1 But orchids, epiphytes and other flowers, as well as ferns, mosses and lichens whose habitat is on trees, abound universally throughout the forests and at all elevations, but varying im speeies. Guatemala Forests. 389 beautiful colors, as bright yellow and rosy red, that would be most valuable for cabinet-making were they accessible, but to bring them out would be too costly. I have mentioned the pine already. There are at least three species. One is the Océte, which is very rich in resin, and is used all over the country for light. In every hut three stakes, or a three-forked stake, is driven into the earth floor ; a flat stone, or water-jar, is placed on top about three feet from the ground, and on this a few finely-split sticks of Océte are kept burning, and a child has the duty of replenishing it from time to time with fresh sticks, I have seen mule-loads of these split sticks on the way to city markets, and in Guatemala city the Ocóte sticks hold their own against the electric light. In the low country, in districts where no Océte grows, some trunk discovered on a river bank, borne down from the mountains by freshets, is a treasure, and supplies the inhabi- tants with light until it disappears piecemeal. This pine grows at all elevations in the temperate and cold climates, and is the charac- teristic tree on the volcanoes, on the ash beds, but here mostly cleared away except in barrancos, and in sandstone soil. There are also some remarkable pine forests near the sea-level. We thus see the pine growing from sea-level to the highest summits, and on the volcanoes to over 13,000 feet high, either in exclusive forests or mixed with other trees. There is a species of pine that is of rare occurrence in the temperate belt. It is called the “ holy pine,” but I have not learned the reason. Perhaps because crosses can be easily cut from the limbs, from its regular opposite branching. Its needles are very long, and bark smooth. There is a curious tree belonging to the order of the Composite that is confined to a particular elevation in a marked way. It is rather gnarled and crooked in shape, but with trunks over a foot in diameter, and reaching a height of thirty feet. Its leaves are willow-shaped, nearly a foot long, glossy green above and white to- mentose beneath, and clustered at the end of the branches. The flowers are yellow, sunflower-like, an inch or more across, and - arranged in large racemes. This tree is so entirely wanting at lower levels, and so regularly makes its appearance at 10,000 feet above the sea, that we call it “our 10,000-footer.” It hardly extends 1000 feet in vertical range. At these elevations occurs another 390 Guatemala Forests. curious tree looking like a gigantic laurel bush, much twisted, gnarled and recumbent, with a smooth red bark, peeling off like the buttonwood. Another tree of limited range is the Pinabete, a spruce. I have noticed it on the Pacific side, at elevations of 9000 feet. It has given its name, Pinabete, to a range of mountains on which it is common. At the upper limit of the temperate belt begins the occurrence of the cedar, or cypress, a lofty tree of large diameter, forming an extensive forest on the table land of Serchil, east of the volcano Zajumulco. In single trees and groups it occurs on many moun- tains, and especially in the great steep mountain ravines. This tree is much used by the natives in their constructions, being 80 easily worked. It is especially used for making planks. These are made by edging a section of a trunk of proper length on oppo- site sides until the finished plank remains. The trees are of such diameter that a single width serves for benches, tables and doors. A cedar, perhaps a different species, grows in the hot country, and is used to make cayukas, or dug-out canoes, and oars. They are light and durable, and large trunks make canoes that carry many people or heavy loads of corn or salt, perhaps four or five tons. They are very sea-worthy, I have safely crossed a lake in one in a storm when the waves ran three to four feet high. The most characteristic tree of Guatemala is one whose name or botanical relations I have not learned. It is the tree that densely covers all the higher summits. In the case of pines, cedars an oaks, it is a question whether the forest is primeval, or has grown upon ground once cleared and cultivated, but these summit forests have clearly never been touched by man, and in the deep recesses of these woods among mossy rocks, in dripping mists and -shut in from the sun one can feel that he is where no human being has ever been before. These trees have large and lofty bare trunks, in appearance like our white oak, but the tops, from the small, glossy green leaves and the dense spray look like the box, and we call it the “box-tree.? Where these forests occur I have never found any ruins, and I am sure man has never occupied that ground. On those table lands and slopes where the forests of this tree have been cut off, they do not appear to grow again, but are replaced by pine, or remain clear and afford pasture for flocks of sheep, from which the Indians derive the wool for their clothing and blankets. Guatemala Forests. 391 These extensive pastures are close-cropped, and poor because of two creeping herbs that carpet the ground, flat and close-pressed to the surface. One of these is a geranium. These pastures have existed probably for centuries, and are mostly above 9000 feet. Below this altitude, next below these pastures, considerable wheat is grown ; also some corn, but this does not thrive well above 8000 feet, but below that elevation it is the principal crop to the sea- level, and is the universal and chief food of all the people. At 8000 to 9000 feet we are also in the region of the potato. These are small, but have such a nutty and delicious flavor that, cooked in their jackets one can eat them like nuts, without any accompaniment ; not even salt seems necessary. They are never planted, but in the dry season a row of men and women begin at the bottom of a slope and hoe the ground down-hill-ward, picking up all the tubers that appear, and enough remain for seed for the next crop, while at the same time the ground is made mellow for their sprouting, all over the ground as if they had been sown- These potatoes are packed in nets or large leaves lined with grass, and carried on the Indian’s back to the lower country and the cities for sale, To make the story complete I must add oats to the list for this region, but they are raised only to a small extent, and not at all by Indians, and only for the horses of the hated white man. And now we must descend lower and leave this lovely and attractive region of bright sun and balmy breezes on one day, or on one side of a mountain, and of driving mists and chilly winds on the other. The conditions of life seem near perfection, no enervat- ing heat, no insects, no malaria, seldom frost, and no snow, hail, or other inclemency. It is a sanitarium unexcelled, and would be a perfect resort for summer or winter, and may be when the Inter- Continental Railway is built. On these charming alfos.and table- lands the native races have lived for ages, slowly gaining headway on the forests and deriving a subsistence, as do their descendants at the present day, by the cultivation of corn chiefly, and also frijol, or black beans, potatoes, a sweet pumpkin, and chile, or red pep- pers. As now, they made their picturesque clothes from the cotton of the hot lands, and the wool of the cold. But, though they lived ina Paradise, and perhaps for that fact, they do not seem to 392 Guatemala Forests. have lived in peace. The many languages surviving to this day in mere fragments of tribes, in isolated patches, and often mixed, would seem to show that many different peoples came here and. took possession of the fruit of previous occupants, and were in their turn subdued or driven away from their mountain fields. Thus the cupidity and necessity of races or classes is ever making turmoil and changing the established order. These people seem fixed to their soil, like the very trees. Sometimes a village seems all that remains of a race, surrounded by other languages, unintel- ligible to it.. The languages, traditions, and racial characters of the various tribes of Guatemala Indians area rich field for the study of anthropologists, and is almost unknown, save what the German, Dr. Behrendt, did in his short life, and whose manu- scripts fortunately fell into the hands of our own accomplished anthropologist, Dr. Brinton, of Philadelphia, who is giving the results to the world. As we descend below 8000 feet the oak becomes an important element in the forests. There are several species of the scrub, black and willow, or chestnut kinds, and none like our white or red oaks, as far as I have seen. As the pine characterizes the lava, ash and sandstone soils, so the oak does the limestone and schist, as well as ash soils. The oak forests are generally more sparse than others, and seem secondary ; that is, have overgrown ground cleared one time by the ancient inhabitants. On lava and ash soils, especially on rocky slopes and in barrancos, the pine and oak are often mingled. Along the ancient Indian roads are rows of oaks, with curiously gnarled and curved trunks, looking very ancient. This oak often divides near the ground into two horizontal arms, and from these several vertical trunks rise up into low trees. There are also other common trees along the ancient paths, an elderberry of tree-like size and form, and a euphorbia, low and gnarled, but with trunks several inches diameter; also cactus trees, wild cherries and box elder. At this altitude, also at 8000 feet in the upper temperate belt, occurs our own well-known sweet gum, the Liquidambar styraciflua L. I have'met it only on the Pacific side, and on one mountain of the interior, forming green groves about springs and brooks on the mountain side, while all the other trees were brown or dull in the dry season and in the dry belt. Guatemala Forests. 393 From 7000 to 3000 feet elevation the country is so thickly inhab- ited, cleared and cultivated that the forests are small and unim- - portant, except on the Gulf slope of the mountains, where the forests are very dense and little known. I have penetrated through them for three years, yet can hardly say I have seen them. One must hew a path through them with axe and cutlass, and can see only the numberless and thickly matted and intertwined vines, lianes and briars, ferns, bamboo-grass and knife-grass, will brush and bother unending, and the close-standing trunks of the un- known trees; but their flowers or foliage never. After three years I have not yet seen the leaves of the cedar, mahogany, silk- cotton and others whose identity I have otherwise learned. But the reason partly is that I had duties that prevented my making a special study of such matters. I have gone up moun- tains where the underbrush was so densely matted that my cutter ahead would open only a tunnel next the ground high enough for us to crawl on hands and knees for distances of several hundred feet at a time. Such circumstances are not favorable for observa- tions of Nature. At these middle altitudes fruit trees come forward ; but there are very few wild fruits—a wild plum, a wild cherry like ours, the large zapate and the manzanilla, are all that occur tome. The plum is yellow, and rather sour and astringent. The wild pigs, or peccaries, of which there are three species, are very fond of them. The monkeys, of which there are two species (the Spider and the Howling), live to a great extent on the zapate, whose tree is large and lofty. The Indians are also very fond of it; and make distant excursions into the woods to hunt for it and for wild honey. Sometimes in the depth of the woods one comes to a large zapate tree, with a rude ladder of poles fastened to the trunk extending up to the top, for gathering its fruit. Some families keep secret certain zapate and bee trees, and visit them each year. Of cultivated fruits at these altitudes there is the Agnacate (called Palta in Peru and Alligator Pear in the West Indies), the apple and the peach. There are few Indian villages and hamlets that are not rosy with peach blossoms in the season. Rose bushes, too, and gera- niums in profusion are about their huts and fences. Apples are not so common, and appear to be of late introduction. Coffee comes into cultivation at 6000 feet, but thrives best at 3000 to 4000 feet. ee 394 Guatemala Forests. And now comes to our notice the silk-cotton tree, or Ceibo, with its great buttressed trunk and its wide-spreading branches. This tree is very common in all the lower forests down to sea-level. The wood is light, and often used for dug-out canoes, but they last only two years without decaying. There is another tree, with a beautiful straight cylindrical trunk, whose wood is so soft and elastic that an axe almost sinks into it at one blow, and can hardly be pulled out again. There is still another peculiar tree whose wood is so hard that, in spite of efforts, I have never known one to be cut down, the cutters always giving up in despair, and when it has to be removed the Indians build a fire'around it, and keep it up until the monarch falls. Already before we pass below 3000 feet the sugar cane and cotton are planted, but coffee at 6000 and cane at 4000 are on rare occasions killed by frosts, as happened winter before last, produced by the same cold waves that carried destructive frosts to lower Florida and Cuba. Also now occur all the well-known tropical fruits, — mango, orange, lime, pineapple, plantain, custard apple and banana, and they improve downwards to sea-level. Below 3000 feet, in the tierra caliente, we are in a torrid climate. Everywhere, except in the dry belt, vegetation is exuberant, over- powering. Itis a hard and expensive struggle to keep ground open enough for cultivation, and neglected ground soon reverts to forest. Even in inhabited parts all the unused spots of ground are so covered that houses and fields are hidden in a general view, and it seems a marvel where all the people live who are known to in- habit the place. But the greater part of Guatemala below 3000 feet is now uninhabited, and covered with rampart forest, primitive or secondary. Two ancient cities are found in this forest, and at many other places are remains, showing that in ancient times @ dense population existed where now is forest. These forests at sea-level have been described by others in terms of admiration and rhapsody, as by Charles Kingsley, and I need not undertake it. I have travelled by canoe up and down various rivers for some 800 miles, on broad expanses with views over desolate marshes, and in profound narrow channels hemmed in by lofty precipices, and under a leafy archway, the branches of trees on the two banks meeting overhead. Sometimes two, opposite fallen trees will bar the way, and an opening has to be cut. A Guatemala Forests. 395 peculiarity is that one cannot boat along the shores, for trees over- hang and shoot out at all angles over the water to reach the sun with their tops. There is a:palm-tree that has the peculiarity of sending its trunk out horizontally from the bank, only a few feet from the water, for some forty feet, and then turning up vertically and spreading its crown of leaves to the sun. There are very many species of palm. Most of them are in the hot country, and in rich, moist hollows, or on river bottoms. Many send up their leaves in graceful sweeps from a subterranean stock, others rear their crowns on lofty shafts. The cocoanut palm likes the immediate sea-shore best, the manuca, flourishes along the great rivers. There is a peculiar palm that prefers thedry belt, abounds on rocky hills, and extends up to 5000 feet above sea, or over. This is highly valued, its leaves being used for weaving hats and petates, the mats or palm cloth universally used for sleeping rugs and for wrapping baggage and goods for transportation by mules or on the backs of Indians. Palm-leaves are very extensively used in hut-building, especially roofing ; also by travelling parties, - to make temporary shelters, called Chiampas, to pass rainy nights in the woods. But it requires the skill of the Indians to make them waterproof. In a few minutes fifty men can erect these chiampas, and sleep dry all night in a pouring rain. The mahogany, of which there are two or more species, never forms a forest, but occurs in clumps or singly among other trees, — and the same is the case with the rubber tree, of which also there are several species. These trees occur scatteringly through all the forests, aggregating a great total. During a freshet I have seen hundreds of mahogany logs dashing down the rapids of the Mumacinta River; to be caught up and loaded on ships at its mouth on the Gulf. Also many cedar logs came down from the upper affluent, the Ococingo River. The rubber trees are not cut. down, but only bled at intervals, until they succumb. The white Sap, or rubber milk, hardens in the air to brown-black, quivering cakes, which are carried by men, mules and canoes to the sea-coast for shipment. The rubber-hunters penetrate the woods every- where, and endure great privations ; they have no fixed abiding- Place, but move from tree to tree, gathering their crop pound * On swampy sea-shores and up the swampy rivers and on coral key the impenetrable mangrove holds sway. _ 896 Guatemala Forests. by pound. On the contrary, the mahogany-cutters, when a place is found with enough trees for a season’s cutting, build themselves a village of substantial huts and keep house, bring with them into the forest wives, children, pigs, chickens, dogs, and all their lares and penates. They may stay one year, or many. But finally, the woods being exhausted of suitable trees, they all depart, the houses decay and fall, the forest regrows and resumes its sway, and all that remains years afterwards are a few stunted banana, orange and mango trees, smothered and hidden by the lusty native forest. There is a large tree very frequent in the dry plains and low hills of the hot lands called the ramon tree. Its leaves are glossy green and leathery, of small size, and afford, with the twigs, a most nutritious fodder for cattle and mules. When they have it they will not touch grass. Itis sweet and mucilagi- nous. For months my mules have depended on it. I had nothing else tu give them. Last of all we come to the logwood, which grows only along the margins of sluggish rivers, lagoons and marshes and in swamps at or near sea-level. I know of two species, brazil-wood and campeachy- wood. The latter is the most valuable, I suppose, because the color of its decoction more closely imitates the color of the red wines, in whose manufacture it is so extensively used. As our imported wines bring high prices, logwood has a corresponding value. It sells by the pound. It is a heavy wood; a stick four feet long needs to be only a few inches in diameter to weigh 100 pounds. On account of its peculiar habitat it is hunted by canoe, and when cut has to be carried by canoe to some shipping-point. It cannot float. It sinks to the bottom like a stone. During the last 300 years thousands of tons of it have been shipped from Belize, and by accident so many logs have sunk to the bottom of the harbor and been lost, that now, when it is proposed to ‘dredge the harbor to improve it and fill up certain shallows in the manner of the Potomac Flats, it is believed that the recovery of this logwood will go far towards paying for the work. The second cause for the diversity of plant life I gave as the meteorological influence of topographical features on climate. As the moisture-laden trade winds from the Caribbean Sea reach the land, and they are deflected upwards more and more as they blow inland, and as the mountains rise higher and higher. This ascension Guatemala Forests. 397 rarifies the air, cools it and reduces its capacity for holding aque- ous vapor, and results in condensation and copious rainfall. It is. like squeezing a saturated sponge. When the culminating sum- mits of the Cuilco Mountains, the Sierra Madre, Sierra de Chania and Sierra de las Minas are reached, the last squeeze is given to- the sponge and the winds cross over to the interior table lands, dry. This causes a dry belt along the leeside of these mountains. extending from Facaná and Cuilco in the northwest by way of Huchuetenango, Chiantla, Rabinal and Salamá to Zacapa and Chiquimula in the southeast. As the air descends from summits of 12,000 to 8000 feet high to the interior plains of only 7000 to 1000: feet elevation, it expands again and takes up moisture from the- soil, dessicating the climate further and making the dry belt a very marked feature of the country. One writer even calls the low hot plains of Zacapa a “ desert.” The pine is very common in this belt at all elevations in favorable situations, and also the oak above 3000 feet. In the driest parts and ‘in rocky places the character of the vegetation is special and peculiar. Cacti, thorny mimose, and many kinds of thorny and prickly shrubs abound. As the air rises again, or the higher currents reach the summits of the moun- tains facing the Pacific, the sponge, replenished from evaporation over the dry belt, is squeezed again, causing mists and copious. rain, and limiting the dry belt to the south and southwest. The Pacific slope has a moist, tropical climate of its own from: the influence of the ocean winds, and is independent of moisture brought from the east. Finally, I have to mention a third great cause affecting the: forests of Guatemala; the influence of the ancient people who cleared nearly or quite all the ground that is cultivated or pastured) to this day, and much more besides that has become overgrown: again with forests. The general proposition will hold that all the clearings of the ancient people in the dry belt, and most of them in its semi-dry borders, have remained cleared, whether cultivated and pastured or not, excepting grass, weeds and shrubbery scattered and in clumps. But to this general rule there is a remarkable exception. In favorable situations, as to moisture and depth of soil, pine forests, with some oak, cover the ancient fields and village sites. In such clean open pine forests, terrace walls, ruined: structures, and whole villages are found, but all very ruined andi ancient-looking. 398 Guatemala Forests. A great pine tree may blow over and expose under its roots a stratum full of potsherds and other remains. Not far off open pine woods may border on a dense primitive forest hardly pene- trable, the line between the two sharp and distinct, showing where the ancient axeman stayed his hewing. Pine forests also cover the country about the ancient city of Quirigua, on the Caribbean Coast, and I believe cover the fields of the dense population that must have supported a city so great as shown by its numerous and artistic sculptured remains. The city of Zikál is also hidden and covered up in the deep woods, with some of its walled towers yet reaching above the great forest trees, but I do not know whether these are pines. It appears then that many primitive angiosper- mous forests have been replaced by pine forests through the inter- vention of the ancients, but in the moist hot regions other angio- spermous forests have followed the primitive ones destroyed by In the valleys of the Salegn4 and Lagartero the heavy rains have denuded the ancient fields of their soil, leaving a stony desert over many square miles, and where forests can never again find a footing. And these curious stony regions now deserted and deso- late are stre vn everywhere with remains of former populations. In the Petten, in the northern part of the Republic, are great areas, bare of woods, and grass-covered, called Sabanas. These are also ancient fields, now unused and unoccupied except at a few small villages for raising cattle. The limestone hills and ridges remain covered with the primeval forest, and at their bases and also at the borders of the inhabited regions the line of division between Sabana and forest is as sharp as when the ancient man made his clearings. I recognize two causes that in their combined action have pre- vented the renewal of the forest. These Sabanas are in the mid- dle of the lowlands between the Caribbean Coast and the moun- tains. As the saturated winds reach the forests on the Coast, their cooling influence causes heavy precipitation, the same as a moun- tain. The coast rains are well-known. But as the winds go over the interior plains without ascending, no further precipitation takes place till they reach mountains ; hence the middle plain acquires the character of a partially dry belt, so that for several months in the dry season no rains occur, and the ground is parched and the vegetation partially dries up. + Mountain Upthrusts. 399 Now it happens that the region cleared by the ancient inhabi- tants has a tough clayey soil of such a nature that it bakes dry and hard in the dry season ; grass and weeds dry up, and young trees that would germinate in the wet season are as regularly killed in the dry. These Sabanas show numerous ancient remains; and these and also the pine forests deserve to be thoroughly examined by archæologists. Much might be learned to shed light on the studies already made on the more modern ruined cities and sculp- tured temples of Central America. MOUNTAIN-UPTHRUSTS. BY CHARLES A. WHITE. ! ERTAIN of the mountain ranges of the western portion of our national domain exhibit in a clear and striking manner the evidence that they have originated in uplifted folds of the earth’s crust. One of the simplest and most characteristic of these orogenic folds is the one in which the Uinta Range of mountains originated. Other uplifts of a similar character have occurred, but which, having been of limited longitudinal as well as lateral extent, have resulted in comparatively small clusters of mountains, and not in mountain ranges proper. The Black Hills of Dakota have originated in one of these circumscribed uplifts. In Northwestern Colorado two uplifts occur which, so far as the character of the displacement and of the formations involved are concerned, are similar to those which have just been referred to ; but they have occurred within such narrow limits, respectively, that they have each resulted in only a single mountain. The limits of each of these uplifts are so sharply defined, and the amount of vertical displacement of the strata involved is so great, that I have designated them as Upthrusts A description of these upthrusts is the special object of this article. But as they are structurally connected with the great Uinta fold and with other neighboring displacements, it will be necessary to devote a considerable part of it to their description also. 1 Published by permission of the Director of the U. S. Geological Survey, The substance of this article will be embraced in one which is to appear in his Ninth Annual Report. 400 Mountain Upthrusts. The great Uinta fold has usually been described as terminating abruptly in Northwestern Colorado. As a conspicuous fold it does so terminate there; but continuous with its axis to the eastward there is a long, gentle anticlinal, which reaches by a broad curve to the foot-hills of the Park Range—a western porton of the Rocky Mountain system. This I regard as a continuation of the Uinta fold far beyond its reputed termination, and also, in connection with other facts, as indicating structural relationship between the Uinta and Park Ranges. I therefore divide the Uinta fold into two portions— namely, the Uinta fold proper, and the inceptive portion of the same, The Uinta fold proper is about one hundred and fifty miles in length, and from thirty to forty miles in width at the extreme limit of the upturned strata at either side. Its western end is blended with the Wasatch Range in Utah, which it meets at nearly right angles. Its eastern terminus is about thirty miles within, and east of, the western boundary of Colorado, and about the same distance from the northern boundary. Its axis, except the slight southward inclination ofits eastern end, is approximately cast and west, and at nearly right angles with that of the Park Range.

Again, although the Archean rocks are theoretically represented in that section, they have not been brought to view in the axis of the fold, because even the immense erosion which the uplifted strata have suffered has not been sufficient to reach them there.! There- fore, in estimating the amount of vertical displacement which has taken place in the Uinta fold, I have reference only to the formations from the Uinta Sandstone to the Laramie Group (inclusive). Now, referring to the foregoing table, we find that the minimum thickness of these formations aggregates twenty-three thousand eight hundred feet. Add to this five thousand feet for the height above the level of the sea at which the lowermost strata of the Uinta Sandstone have been observed, and we have an aggregate of twenty- eight thousand eight hundred feet. The evidence seems to be con- clusive.that the elevation of the fold began immediately upon the close of the Laramie period ; and it is confidently assumed that none of its strata were then much if any above the level of the open sea. Hence the conclusion that the full amount of vertical displacement in the Uinta fold has not been less than twenty-eight thousand eight hundred feet. The evidence derived from a study of the great fold seems also to ` be conclusive that its elevation was continued between the close of the Laramie period and the close of the Tertiary ; and other evi- dence is equally conclusive that continental elevation was continued during the same time. That is, it is assumed that the orogenic movements which have resulted in *he production of the Uinta and other mountain-making folds were approximately synchronous in their origin and coeval in their duration with the epirogenic” move- ments by which the great continental area upon which those folds now rest was raised to its present elevation above the sea.* 1 Archsean rocks are exposed within a limited area upon the northern side of the fold; but they were evidently a part of an uplift which was older than the fold. 2 Etym., Hze:pos—mainland, or continent. 3 Certain epirogenic movements must necessarily have taken place to form the barriers by which the Laramie sea was cut off from the ope? oceans. Local unconformity among the Laramie strata which has been observed near the top of the group in Southern Wyoming indicates that . certain other premonitory movements took plate before the Uinta es was well defined: Mountain Upthrusts. 403 The inceptive portion of the Uinta fold is, of itself, by no means a conspicuous geological feature—first, because a broad valley or basin, which I have called Axial Basin, is formed along the greater part of its length by the erosion of the strata which have been up- lifted there; and second, because the uplift is comparatively slight. A transverse section (Fig. 2) across Axial Basin shows the character of this portion of the fold, and it also shows the formations which are involved in it.

The line xx indicates propor- tionally the longer diameter of the Yampa Mountain upthrust, and ~ also its position with reference to the inceptive axis. Horizontal scale: 4 miles to the inch. Vertical scale: 1-12 inch to 1,000 feet. This comparatively slight fold becomes of great importance be- cause of its evident relation to the great Uinta fold, and especially because of the presence upon, jts axis of the two upthrusts which have been already referred to, the presence of each of which is marked by an isolated mountain which rises abruptly out of Axial Basin. These are, Junction and Yampa Mountains, which are plainly outlying, isolated members of the Uinta Range. The main portion of the Uinta fold terminates at its eastern end by a dip of the uplifted strata which is quite as abrupt as that at either side of it, and which carries them far beneath the surface of the adjacent lowland. Going now, only two or three miles east- ward from this eastern terminus—where we have seen the later formations dip so suddenly from view—we come to the western border of Junction Mountain upthrust. Here we find the same Strata to rise again, even more suddenly than they disappeared ; and 404 Mountain Upthrusts. we also find that the formations of Paleeozoic age—which constitute the high mountain-peaks of the Uinta Range only a few miles away —are here again uplifted, not only to the surface of the low land around the mountain, but toa maximum height of nearly two thou- sand feet above it. The strata involved in this uplift—which, be- cause of its sharply-defined limits and of the vertical displacement of these strata, I have called an upthrust—occupy an elongate oval area, the extreme longer diameter of which is nearly twelve miles, and the shorter about four miles. The direction of the longer diameter, being in a northwestward and southeastward direction, is obliquely transverse to the general trend of the axis of the Uinta fold. In this respect, as well as by the peculiar character of dis- placement of the strata involved, the isolation of this upthrust is quite complete, although it lies so near the terminus of the main portion of the Uinta fold and upon the axis of its inceptive portion. So sharply have the strata been uplifted in this displacement that they are either faulted or are nearly or quite vertical at a portion of each side of the upthrust, and they also dip very abruptly at other portions and around its ends. The Mesozoic formations, through which the older ones were forced, lie all around the mountain, but immediately adjacent to it they are largely covered from view by the strata of the Brown’s Park Group, which lie unconformably upon them. The disturbance which these Mesozoic formations have suffered in that neighborhood beyond the base of the mountain is s0 slight that one cannot recognize it as having been connected with the upthrust movement. That is, their position as marking the pres- ence of the inceptive portion of the Uinta fold and of certain sub- ordinate uplifts does not seem to have been changed by the localized upthrust movement. The Mesozoic formations,—which must have necessarily risen on the top of the older ones within the upthrust area,—have been removed by erosion, as has also a large part of the full thickness of the Carboniferous strata which came up beneath them. Therefore, only strata of Palæozoic age now enter into the structure of the mountain proper ; while the upturned edges of the later ones, where they have not been sharply severed by faulting, lie around its base. Going from Junction Mountain about sixteen miles along the axis of the inceptive fold, we pass all the way over the low lands of Axial Basin, the surface of which is there mostly occupied by the and the Junction, and Yampa Mountain Upthrusts. Fra. 3.—Section showing the eastern end of the Uinta fold Mountain Upthrusts. 405 - Brown’s Park Group, and reach Yampa Mountain, which rises directly upon that axis, as does Junc- tion Mountain. Here we find that the descrip- tion that has just been given of the Junction Mountain upthrust will apply in all essential re- spects to this. All around the base of Yampa Mountain the strata of the Brown’s Park Group cover the immediate borders of this upthrust, even to a greater extent than they do those of Junction Mountain upthrust; but it is readily seen that the two mountains are essentially identical in structure and character, and that they have been produce ina similar manner. Yampa upthrust, however, is smaller than the other, and it is also much farther away from any other greatly displaced strata. Its outline is oval, the longer diameter, including all the strata involved,—not much exceeding seven miles in length,—and its shorter diameter is less than four miles. The longer diameter is nearly at right angles with that of Junction Mountain upthrust, and it is nearly transverse with the inceptive portion of the Uinta axis, upon which it rises. The relation of these two upthrusts to each other and to the main and inceptive portions of the Uinta fold is indicated by the section, Fig. 3. a, Yampa Mountain; b, Junction Mountain; c, eastern end of the Uinta Range; d, Yampa River, before entering Junction Mountait’s €, Snake River; U., Uinta Sandstone; Carb., Carboniferous strata; J.

The amount of vertical displacement is about the same in each c of these upthrusts, the extent of which given in the foregoing table) and from the contour | lines on the published topographic a of that . 406 Mountain Upthrusts. region. The contour line which cuts the top of the Uinta Sandstone in both these mountains passes along the southern side of Axial Basin, approximately at the base of the Laramie and the top of the Fox Hills Group. Referring to the preceding table, we find the thick- ness of the intervening formations to be eleven thousand eight hun- dred feet. It is therefore plain that the amount of vertical dis- placement in both these mountains is not less than is represented by those figures. That is, within the narrow and sharply defined limits that have been described, the strata of which both these mountains are composed have been thrust up a vertical distance of more than two miles,—which in the case of the Yampa upthrust is nearly equal to one-third of the longer diameter of the area affected by it. As indicating that the amount of vertical displacement in these upthrusts is really greater than has been mentioned, it may be stated that the Fox Hills and Laramie strata referred to have themselves been elevated to a considerable extent in the adjacent Danforth Hills uplift (as shown by the section, Fig. 2). This figure will also serve to illustrate the relation of the Yampa upthrust to the inceptive fold and to the adjacent Danforth Hills uplift. That is, if within the space indicated by the length of the line xx the strata should be elevated until the base of the Carboniferous series reaches the place of the uppermost dotted line, the vertical extent and lateral restriction of the Yampa upthrust will be indicated. i - It is true that the vertical displacement in the case of these two upthrusts is much less in amount than is that of the great fold ; but the amount of displacement is far more remarkable in the case of the upthrusts than it is in the case of the fold, because of the very narrow limits within which the displacements in the former case have taken place. The narrow and sharply defined limits of these upthrusts, and the severing of the displaced portions of the forma- tions from the great mass of each respectively, with little or no gen- eral disturbance of the latter beyond those limits, may be comp to the action of a large punch on being forced by great power through a number of thick iron plates. The comparison will be more com- plete if we conceive that the cutting-border of such a punch had become dulled at certain places, so that a part of the iron through which it was being forced would drag and not be sharply severed. Portions of the uplifted strata at the base of both these mountains Mountain Upthrusts. 407 seem to have thus dragged during their elevation ; while other por- tions were sharply severed, as if the displacement had really been done by a huge punch acting from beneath, producing an ordinary fault there. The evidence that the orogenic and epirogenic movements which have resulted in the present physical conditions in the Western por- tion of our national domain were coéval with each other, seems to be unmistakable, so far, at least, as the time-limit of each series of movements is concerned, But, considering for the present only the orogenic movements, it is evident that the uplifting force has been applied along certain lines with great inequality, both as regards the amount of force locally exerted and the duration of its application. That is, in the region especially referred to in this article there are indications that while the orogenic displacements now observable there were in progress there were local arrests and accelerations of the elevating movement, which produced a final diversity among them that did not exist in their inception. For example, the present structural condition of the Uinta fold Seems to warrant the assumption that it was once, along its entire length, in the condition in which its inceptive portion now is, except for the presence of the upthrusts. Furthermore, that these upthrusts, as well as the main portion of the fold, continued their upward pro- gress, while the present inceptive portion remained as it was when its elevation was arrested. There are other plain indications of the arrest and acceleration of uplifting force in that region; but the upthrusts rising upon the inceptive fold constitute the most striking examples, The elevating force was not only strangely concentrated in the case of the two upthrusts, but it seems to have been applied in an unusual manner, especially when we consider the position of the longer axis of each with relation to that of the other, and also to that of the Uinta fold. It has been mentioned that the longer axis of the Junction upthrust lies in a northwest and southeast direction, and that of the Yampa upthrust in a northeast and southwest direc- tion. Viewing these upthrusts only in relation to the Uinta fold proper, and regarding them as nearly or quite isolated portions of e same, one would naturally expect to find their longer axes coin- ciding with a line projected from the axis of the main fold, and he would also expect to find the intervening strata along that line to 408 Geology of Johnson County. have partaken largely in 'the upward movement: That is, in view of the simplicity of the main portion of the Uinta fold, one might naturally expect that the uplifting force which was applied along its entire axis would have acted strongly and continuously, if not uniformly. But the foregoing statements show that neither of the upthrust axes coincide with such a line or with each other, and also that only a comparatively slight elevation of the strata has occurred along what I have designated as the inceptive portion of the Uinta fold. These upthrusts are so extraordinary in their character that one instinctively desires to know how they were produced. I freely admit my inability to reply to such an inquiry in a satisfactory manner ; and for the present I will offer only the following sug- gestion. Assuming—as the evidence seems to warrant us in doing —that the completion of the main Uinta fold and that of the Park Range were contemporaneous, or nearly so, they constituted ponder- ous buttresses at either end of the strongly-curved inceptive portion of the Uinta fold. It is not strange, therefore, that any elevating force that may have been applied along the axis of that. inceptive fold—which stretched across the intervening space—should have been diversely, if not abnormally, applied. , NOTES ON THE GEOLOGY OF JOHNSON COUNTY, IOWA.

In this paper I have endeavored to elucidate some of these phe- nomena as observed in Iowa, and it is hoped that it may not be without at least some value to the broad field of science. In the hard Devonian limestone in the west bank of the Iowa River, at Iowa City, are numerous (often large) very interesting potholes, which have been formed by the action of running water ; and as they shed so much light upon the condition of things at this locality at the beginning of the Carboniferous age, a short descrip- tion of a few of the more prominent ones here i is deemed not to be without interest and value. The rocks in which these potholes are formed, rises toa height of from twenty to forty feet above the water in the Iowa River. Pothole number one: Circular, sides smooth and symmetrical, sloping gradually to the bottom, upper margin rounded, depth five feet, diameter at the top two foal, and at the bottom one foot. Pothole No. 1. The following diagram will illustrate this description :— One foot from this is another smaller subcircular pothole, having a depth of two feet and a diameter at the top of one foot, and at the 410 Geology of Johnson County. bottom of ten inches, with unsymmetrical but smooth sides; upper margin smooth and somewhat flaring. - About half way from the top to the bottom, cavities have been formed in the sides by the action of the water which formed the pothole. The upper margin of this pothole has a small channel eut through to the east, apparently by the overflow. Pothole number two: This is one of the largest and most inter- esting examples to be found here. This pothole has been formed y the union of several minor ones. Its longest diameter is from east to west, somewhat subovate in marginal outline, sides unsym- metrical but smooth, more or less gently sloping to the bottom, upper margins unevenly rounded, depth seven feet, length from east to west seven feet, and width of the eastern portion at the top two and one-half feet, and marginal width of the western portion four and one-half feet, contracting at the bottom to a width of two and one-half feet. | In the west side of this pothole, about midway from top to bottom, large, more or less ramifying cavities, varying from three feet to eight feet in extent, have been worn by the action of the water which formed the pothole. The overflow to the east has cut a channel about three feet in depth and two feeet in width. About four feet to the right of the foregoing is a small bowl-shaped depression, with smooth symmetrical sides, and rounded or flaring margin. Near this is another smaller saucer-shaped depression, having a diameter of sixteen inches, and a depth of six inches- These are beautiful examples of how some of these potholes were begun. The following cut (from a photograph) will illustrate the form and position of “these depressions in relation to the large pothole above describe Pothole nëmbe three: Subcircular in outline, sides somewhat irregular, smooth, upper margin slightly flaring. For the first four feet the sides are nearly perpendicular ; below this point the hole- rapidly enlarges to the east, but soon contracts, and continues its downward course in the form of a gradually-narrowing oblique fissure, that finally unites with a rather large, more or less horizon- tal, crevice between the beds of rock.' 1 This fissure is filled with a black, combustible, carbonaceous mud of bituminous matter, which is usually underlayed and sometimes over~ layed by a reddish-brown clay.

In this same rock are numerous other minor potholes of much interest, many of them showing unmistakable evidence of having originated in a larger or smaller vertical fissure, their upper margins being invariably rounded, or more or less strongly flaring, with often a larger or smaller channel -cut through to the east by the overflow, thus demonstrating the fact that the flow of water which formed them was from the west. Many of these potholes are filled (and all showing evidence of having been originally) with a hard, stiff, reddish-brown, sometimes brownish-black, clay, similar to the underclay of coal seams. Not only are these potholes filled by this clay, but also the numerous vertical and horizontal fissures and spaces between the rock bed- ding filled with the same material. This reddish-brown color, however, is probably due to the infiltration from the, in places, very ferruginous drift material, which immediately overlies them. About thirty years ago, during the geological survey of Iowa by ‘James Hall, important facts (since mostly obliterated by the exten- sive quarrying of the rock) were observed in regard to this phe- nomena; and for the sake of greater clearness in the matter, I here give a partial compilation of the description of it as found in the ‘survey :—? “ In a cliff of limestone of the Hamilton Group, at Iowa City, the following phenomena is’ observed :— “Beneath beds of nearly horizontal limestone appears a black band extending thirty or forty feet: this consists of black carbonaceous mud, the upper part having the character of cannel coal, and the lower part a slaty carbonaceous shale. “Beneath this, and less extended, a thicker layer of greenish- grey clay, of the character of underclay of coal seams, fills the upper and broader part of the cavity ; while below this, and occu- pying the deepest parts, is a coarse sandstone, which follows, in its line of lamination, the curvature of the limestone upon which it lies.” This description is illustrated by the following diagram :— “ Here we have all the phenomena attending a true coal-measure seam of coal: the sandstone, the underclay, and the coal seam rest- ing upon it; and to complete the analogy, the slaty portion of the seam contains fish teeth of carboniferous character. All this 15 : Hall’s Geological Survey of Iowa, Vol. I., Part 1, pp. 129-133 and 265. Geology of Johnson County. 413. enclosed in limestone, which, in the State of New York, where the series is more complete, lies at a depth of more than five thousand feet below the coal measures.” The result of the most critical examination and study of the: phenomena as observed to-day, is such as to corroborate the state-. ment then made in regard to this subject, which is as follows :— “The coarse and fine sand were first transported, and, entering some fissure [probably a pothole] in the rock, continued in deposi- tion in this cavity, while a bed of similar sandstone was being formed outside upon the bottom of the sea. This ceased, and then came the clay, which continued in like manner, while the under clay of an exterior coal bed was in process of deposition. “ Lastly, the carboniferous mud, derived from the material of a coal seam, was filtered through the fissure, filling the remaining space, and spread out in the narrow seam beyond. There is no mingling of the material, as if resulting from the breaking up of a coal seam at a later and modern period. “Every part is as distinct as in the coal measures elsewhere ; and this only could have resulted from a participation in the cause then operating to produce those extensive beds of sand, shale, clay, and coal which make up the coal measures. This point is near the northeast margin of the coal basin, and beyond the limits of any productive coal seams; a few isolated patches of sandstone and shale being all the remaining evidence of the extension of the series in that vicinity.” It is believed that the immediate valley or channel of the Iowa River, from Coalville to Iowa City, and perhaps north from this point, in Johnson County, represents the channel of an old Deyo- nian stream, y Occupying a position in the east side of the valley of the Iowa River, where an abrupt curve is made, near Iowa City, is a patch of soft, friable carboniferous sandstone, having a length of one- fourth of a mile, and a breadth of one-eighth of a mile or less. This sandstone occupies a valley of erosion in the Devonian lime- stone, and which has a depth of between thirty and forty feet. That this was a valley of erosion, formed by the action of flowing water prior to the time when the sandstone was deposited, is- obvious, as the sides of this valley are seen, after the removal of the sandstone, to be smoothed and worn by the long-continued: action of running water. 414 Geology of Johnson County. The channel of the Iowa River, from Iowa City north, in this county, has been eroded to a depth of from twenty feet to upwards of one hundred feet into the hard Devonian limestone. As I have before intimated, it is believed that this valley was formed, to a great extent at least, by an old Devonian stream, and then sub- sequently filled by the sandstone during the Carboniferous age. The glacial drift in Johnson County, so far as it has been observed, is everywhere covered by a profound mantle of loess, so that it can be observed only along the borders of streams, and along the axis of surface drainage, where the overlying formation has been cut through, thus exposing the drift at the bottom. This formation, so far as can be made out, attains a thickness of from four feet to eighteen feet, and is composed of clay, sand, gravel, and boulders. The boulders, however, are rarely observed, except at the bottom of ravines, where they are sometimes quite numerous, and vary in weight from ten pounds to upwards of two thousand pounds. The drift, for the most part, shows but slight evidence of modification or rearrangement of its materials. In some places, however, it contains an abundance of ferruginous matter, so much indeed as to give it, at limited localities, a deep-red color. The gravel of this formation is made up of more or less rounded frag- ments of Devonian limestone, derived from the subjacent strata, smoothed and well rounded, often beautiful striated, pebbles of granite, quartz, trap, greenstone, and others of igneous origin, which have been derived from the north. The boulders are also of the same material and origin with the exception of those of Sioux quartzite, which were derived from the northwestern portion of the State. Devonian fossils (and rarely Carboniferoud, derived from the underlying rock, are also common. The old forest bed is also well represented, and occupies, as is usual throughout other portions of the State, a low horizon in the drift formation. While digging a well on the farm of Mr. Joseph Hedger, about five miles southeast from Iowa City, the forest bed was struck at a depth of about twenty-eight feet. This formation was represented by a dark-brown, slightly-combustible peat formation, which was overlayed by, and slightly mixed with, a layer of coniferous wood and twigs. This peat also contained abundant remains of plants, well-preserved seeds (apparently those of grass), and abundant remains of Coleopterous insects. This bed rests directly upon hard, Geology of Johnson County. 415 stiff, distinctly stratified blue clay. This formation has been struck at numerous localities at a depth of from twenty-eight feet to sixty feet below the surface, in the central portion of this county. A usual feature of the peat division of the forest bed of this region are the remains of Coleopterous insects. The peat at all these localities was evidently formed where it is now found, and are parts of one and the same bed. A limited deposit of similar ancient peat was also discovered in Adair County, one hundred and seventy miles to the westward of Iowa City, on section twenty-two, township seventy-five, range thirty-two. This bed was found to be between two and three feet in thickness. The drift, apparently only slightly if at all modified, rested directly upon it, and it was underlayed by a dull, bluish- clayey bed. At another locality, near Davenport, fifty miles east of Iowa City, a deposit of peat occurs almost upon the very brow of the bluffs that border the valley of the Mississippi. This example is one of unusual interest, in consequence of the existence there of an extensive bed of ancient peat which is covered to th depth of several feet beneath the prairie soil, and the discovery in the clay, - above the peat, of the remains of a mammoth. The following section, compiled from White’s Geological Survey of Iowa, vol I., part i., pp. 119, 120, will show the position of the deposit in relation to the drift :— “No.1, The ordinary prairie soil, one foot. The prairie here extends to the edge of the bluff, gently sloping backward toward the north. “ No. 2. The ‘yellow elay’ or loam, twenty feet thick, iron- stained, frequently distinctly laminated; lamine curved, and have their layers of sand interstratified in some places.

Thickness unknown. “ The exposure was made by the excavation of the Chicago, Rock Island and Pacific Railroad Company, previous to which there was no appearance at the surface to indicate the presence of anything more than the ordinary drift deposit.” Bed No. 5 of this series is undoubtedly only a more thoroughly decomposed and finely comminuted portion of bed No. 4. This bed of peat, also, like that at Iowa City, contains remains of Coleopterous insects. While boring a well on the northeast quarter of section ten, township eighteen, range five, in Linn County, a deposit of peat and coniferous wood four feet.in thickness was struck at a depth of ninety-nine feet below the surface. From this well, into which a tight galvanized iron tubing has been forced, escapes a constant supply of natural, combustible gas (the peat probably being the origin of it), but whether of sufficient quantity to be of practical value, is a question to be answered by investigation. A few miles from this locality another well of the same character is reported. In the northern portion of the State the peat formation is seldom, f ever, observed as a member of the forest bed. These beds of peat are of interglacial origin, and was coexistent with the luxuriant forests of conifers which, in interglacial times, covered the surface of what is now known as Jowa.! The occurrence also of the well-preserved seeds of plants and the abund- ant remains of insects in this formation are features of pecu- liar interest. A critical and somewhat extended study of the forest bed and other superficial formations in different portions of the State, reveals facts which seem to substantiate the theory advanced in regard to the relative age of the peat formations. ` The topography of the surface of Johnson County is, for the most part, peculiarly that of loess regions, being more or tess broken and rolling, the elevations having rounded tops, and more or 1'These beds of peat were believed by Dr. White not to be of interglacial origin.

The valleys of the Iowa River and its tributaries are relatively narrow and deep, and bordered by more or less steep acclivities, and flanked at frequent intervals by deep but narrow and rapidly ascending ravines, and these again often ramify in shallow depres- sions which draw the water quite effectually from nearly all portions of the upland. f The immediate valley of the Iowa River, as I have before inti- mated, attains an average width of one-half of a mile, and a depth below its immediate borders of from sixty feet to upward of one hundred and seventy-five feet. Well-defined terraces are sometimes observed along this stream, and they have been produced by the deepening of the valley by the action of the waters of the stream. As has been before stated, the surface of nearly, if not quite all of this county, is occupied by a loess formation, which effectually conceals the underlying drift formation, except along the valley- sides and the axis of surface drainage, where the overlying deposit has been cut through. This deposit attains a greater thickness along the streams than adjacent to them, and consists, for the most part, of an exceedingly finely comminuted yellow or buff-colored clayey earth, with an admixture of humus in favorable situations, as in the beds of drainage depressions and in the valleys, as well as most usually the more level surface of the upland, which gives to it a color varying from a light-ash to a deep-black. Upon the higher points, however, the soil usually contains comparatively little humus, for the reason that it is swept down by the rains as fast as it is accumulated by the decay of vegetation, and deposited in the beds of ravines and the slight valley bottoms. The following section, taken at the “brick-yard,” in the north- east portion of Iowa City, gave the following result :— _ 1. Very fine brownish “loamy” soil, containing humus—three inches, 2. Very fine and homogeneous yellow-clayey earth—fifteen feet. 3. Very fine and homogeneous bluish-grey, clayey earth, having more or less numerous brownish-drab streaks running through it, and containing numerous fossils, many of which were in a crushed condition—fiye feet. Entire thickness unknown. = The different divisions of this section pass into each other by 418 Geology of Johnson County. very gradual and imperceptible gradations. In a railroad cut, about one and one-fourth miles west of Iowa City, the loess is seen to attain a thickness of twenty-three feet and five inches. The humus-stained division, No. 1, attains a thickness of five inches; while the second, or yellow division, attains a thickness of about twelve feet; and below this, the third, or blue division, which attains a thickness of eleven feet, and rests immediately upon the drift. This portion contains an abundance of fossils, most of which, however, are in a better preserved condition than those of its equivalent at the “ brick-yard.” One mile south of Iowa City the loess is seen to attain a thick- ness of twenty feet, and is very fine and homogeneous throughout, being of a yellow or yellowish-buff color, with the exception of a humus-stained layer, of a few inches in thickness at the top. The yellow clay at this locality rests directly upon the drift, the blue division being absent, as also fossil remains, so far as observed. At Oxford, in the extreme western portion of the county, the typical yellow loess is seen to have a thickness of from fifteen feet to twenty-two feet, the blue division, however, not being present. No fossils were observed in the loess in this region. Occupying the same relative position to the loess, and presenting the same general character as at other described localities, is the drift forma- tion. At this locality, as well as several others in the county, the loess is seen to contain more or less extensive accumulations of fine silicious sand ; also, at two or three places, I observed small accu- mulations, or pockets, of well-rounded and smoothed quartz and greenstone pebbles of drift origin. This material may have been derived from detritus ladened ice, floating from the north and dropping its burden while this formation was in process of deposi- tion. At numerous localities the loess contains abundant calcareous concretions and ferruginous tubules of various dimensions, while at other localities it is devoid of them. At Solon, in the northeast part of the county, the loess is some- what thinner than at the previously-described localities, but i essentially the same, although the lower, blue, division is not noticed, and the upper, black, humus-stained layer, is somewhat thicker, owing to the somewhat less broken surface, and the lessened facility with which the surface is “ washed ” by rains, thus remov- ing much of the humus accumulated by decomposing vegetation. Geology of Johnson County. 419 Below I give a catalogue of all the fossils yet obtained from the loess of Johnson County ; doubtless, however, many others existed which have not as yet been discovered.1 Those marked * do not occur as living forms in the county at the present time :— Zonites viridulus (Mke.). Zonites limatulus * (Ward). Zonites fulvus (Drap.). Patula strigosa * (Gld.). Patula striatella (Say). Ferussacia subcylindrica (L.). Pupa muscorum * (L.). Pupa blandi * (Mone.).

Limnæa desidiosa (Say). Pisidium—sp. (?) Egg-shell of some small Helix. The loess formation constitutes a prominent feature of the super- ficial geology of Iowa, being developed to a greater or less extent over a large portion of the State. It is believed that the material of this formation was deposited during the Champlain period ; and facts seem to demonstrate, moreover, that this was not only a period of somewhat lower level in Iowa as well as other places, than the present, but also that the amount of depression increased somewhat to the northward, so that the streams flowing to the southward had usually a diminished slope, with a consequently slackened flow of the waters, and many greater or less expansions along their course, and from these silt-ladened waters the material of the loess forma- tion was derived. ! For this catalogue of species I am much indebted to Professor B. Shimick, of Iowa Cit ies li ’ y. All the species listed have been personally collected by him, 420 History of Garden Vegetables. HISTORY OF GARDEN VEGETABLES. BY LOUIS STURTEVANT, M.D. (Continued from page 985, Vol. XXI.) Fennel. Feniculum vulgare Gertn. p NEL was used by the ancient Romans, as well for its aro- matic fruits as for its edible succulent shoots. It was also em- ployed in Northern Europe at a remote period, as it is constantly mentioned in the Anglo-Saxon medical receipts which date as early at least as the eleventh century. The diffusion of the plant in Central Europe was stimulated by Charlemagne, who enjoined its cultivation on the imperial farms. Fennel shoots, fennel water, and fennel seed, are all mentioned in an ancient record of Spanish agri- culture of 961 A.D.! There are three different forms recognized, all believed to belong to a common species, Fæniculum vulgare Gertn., but which have received specific names by various botanists. Bitter Fennel. F. vulgare Geertn. . In 1863, Burr describes? a common and a dark-leaved form; in 1586, Lyte’s* Dodcens describes in like manner two varieties. This is the common wild sort, hardy, and often spontaneous as an escape from gardens. It is the Anethum feniculum L., 1763, and the Feeniculum of Camerarius,‘ 1586. Sometimes, but rarely, the leaves are used for seasoning, and the plant is chiefly grown for its seeds which are largely used in the flavoring of liqueurs. The common or bitter fennel is called in France Fenowil amer., Fenouil commun. It appears to be the common fennel or finckle of Ray, 1886, the fænell and fyncle of Turner, 1538. Sweet Fennel. F. officinale All. This form is cultivated more frequently as a garden plant than the preceding, and its seeds are also an object of commerce. AS the plants grow old, the fruits of each succeeding season gradually 1 Pharmacographia, 1879, 308, 2 Burr. Field and Gard. Veg. of Am., 1863, 420. 3 Lyte’s Dodcens, 1586, 305, 4 Camerarius Epit., 1586, 534, History of Garden Vegetables. 421 change in shape and diminish in size, till at the end of four or five years they are hardly to be distinguished from those of the bitter fennel. This curious fact was noted by Tabernemontanus in 1588, and was systematically proven by Guibort, 1869.1! This kind has, however, remained distinct from an early date. It is described by Albertus Magnus? in the thirteenth century, and by Charlemagne in the ninth. It is mentioned as a plant of the garden in nearly all the earlier botanies. It is cultivated throughout Europe, in Asia and in America as an aromatic garden herb. The famous “carosella,” so extensively used in Naples, and scarcely known in any other place, is referred by authors to F. pipe- rium D. C., a species very near to F. officinale. The plant is used while in the act of running to bloom; the stems, fresh and tender, and broken and served up raw, still enclosed in the expanded leaf stalks.* It is, perhaps, referred to by Amatus Lusitanus‘ in 1554, when, in speaking of the finocchio (It.) he says the swollen stalk is collected and said to be eaten, “quod caule turgescente colligitur et esui dicatur.” The common or sweet fennel or Roman fennel is called in France fenouil doux, fenouil de Florence, fenouil de Malta, anis de France, anis de Paris; in Italy, carosella. These names also seem to apply in part to the next kind. In Turkestan, shabit.® Finocchio. F. dulce D C. This form is very distinct in its broad leaf-stalks, which, over- lapping each other at the base of the stem, form a bulbous enlarge- ` ment, firm, white and sweet inside. It seems to be the Finochi or Italian Fennel, stated by Switzer,’ in 1729, to have but recently been introduced to English culture, and yet rare in 1765 ;° but the first distinct mention I find is by Mawe, in 1778, under the name of Azorian Dwarf or Finocchio. It is again described in a very - 422 History of Garden Vegetables. perfect form by Bryant, in 1783,! under the name of Sweet Azorian Fennel. According to Miller’s Dictionary, 1807, it is the F. azori- cum of Miller, 1737. Ray, in 1686, uses the name Foniculum dulce azoricum, but his description is hardly sufficient. It is described for American gardens in 1806.5 It does not seem to have entered general culture except in Italy. The type of this fennel seems to be figured by J. Bauhin in 1651, and Chabreeus, in 1677, under the name Feeniculum rotundum flore albo. The Finocchio or Azorean Fennel is called in France fenouil de Florence, fenouil sucre, fenouil de Bologna, fenouil d’ Italie; in Ger- many, grosser susser florentiner Fenchel, grosser bologneser Fenchel, florentiner Anis; in Holland, groote zete Bologneser grosser ven- kel; inDenmark, dvergfennikel; in Italy, finocchio dulce. * The general name for the Fennels is in France fenouil; in Germany, fenchel; in Flanders and Holland, venkel; in Denmark, fennikel; in Italy, finocchio; in Spain, hinojo;* in Arabic, rais- niji; in Egyptian, savin or tshamar hoout; in Greece, marathron; in Hindustani, owa;* in India, souf or so, ooa; in Japan, sen rio, kure no vomo;? in Yemen, sekamar.® Fennel-flower. Nigella sativa L. The seeds, on account of their aromatic nature, are employed as a spice in cooking, particularly in Italy and Southern France. It is supposed to be the gith of Columella and Pliny, in the first century ; of Palladius, in the third, and of Charlemagne, in the ninth.” The melanthion of Columella, in the first century, seems a descriptive name for his gif. It finds mention as cultivated in most of the botanies of the sixteenth and seventeenth centuries ; is recorded by Vilmorin™ among plants of the garden, as also by 1 Bryant. Fl. Diet., 1783, 53. 2?

On account of its objectionable odor it was avoided in Rome,’ but it was probably eaten by the common people as now in southern Europe. It is mentioned in the earlier European herbals as in cultivation, and in England, in 1551, by Turner,’ and in 1548 by Tusser.* In Peru, Acosta® says, in 1604, that “the Indians esteem garlike above all the rootes of Europe,” and in Mexico, even earlier, Peter Martyn,‘ in 1577, noted its presence. It was in the garden of the Choctaw Indians, in North America, before 1775.’ It is said to have been introduced to China 140-86 B.C., and to be found noticed in vari- ous Chinese treatises of the fifth, sixteenth, seventeenth and eigh- teenth centuries.

Cucumis anguria L. This vegetable is described by Marcgrav,! in Brazil, in 1648, the name Cucumis sylvestris Brasilee indicating an uncultivated plant. Ten years later Piso? described it also as a wild plant of Brazil under the name guarerva-oba or Cucumer asinius, and gives a figure. It has also been found in the Antilles and continental tropical and sub-tropical America, New Granada and South Flor- ida.’ It is not mentioned as cultivated in Jamaica, by Sloane,‘ in 1696. Its fruit is mentioned as being used in soups and pickles, apparently gathered from the wild plant, by Long, in 1774, Tit- ford,’ in 1812, and Lunan,” in 1814. It is, however, cultivated in French Guiana and Antiqua. Although described by Ray, in 1686 and 1794, and grown by Miller in his botanic garden in 1755, it yet does not appear as if in the vegetable gardens of England in 1807,” although it was known in the gardens of the United States" in 1806. In France it was under cultivation in 1824 and 1829,” but apparently was abandoned, and was reintro- duced by Vilmorin in 1858.3 The small girkin, round prickly gherkin)!

Burr? says the plant is sometimes eaten boiled, but it is generally pickled in its green state, like the common cucumber, and adds that it is not worthy of cultivation. Good King Henry. Chenopodium Bonus-Henricus L. The leaves are eaten as a spinage. The plant is now but rarely cultivated. Gerarde speaks of it in 1597 as a wild plant only, while Ray in 1686 refers to it as frequently among vege- tables, and Bryant in 1783 says formerly cultivated in English gardens, but of late neglected, although certainly of sufficient merit. In 1807 Miller’s Dictionary says it is generally in gardens about Boston, in Lincolnshire, and is there preferred to spinage. It cannot have ever received very general culture, as it is only indi- cated as a-wayside plant by Tragus, 1552; Lobel, 1570 and 1576; Camerarius, 1586; Dalechampius, 1587; Matthiolus, 1598 ; Cha- bræus, 1677, etc. Its value as an antiscorbutic finds recognition in its names, Bonus-Henricus and tota bona. It is called in English, Good King Henry, Fat-hen English mercury, All Good,‘ Wild or perennial spinage,> goose foot; in France, anserine bon-henri, bon-henry, epinard sauvage, patte d'oie triangulaire, sarron, serron; in Germany, gemeiner Gansefuss; in Flanders and Holland, ganzevoet ; in Italy, bono enries.® It is recorded for American culture by Burr in 1863, and has now become naturalized about dwellings in a few localities. I have never observed it growing. Gourd. Lagenaria vulgaris Ser. See under Squash. It is generally supposed that the Gourd is uneatable. This is true of some varieties, but not of others. Duchesne,’ in France, speaks of the trompette gourd as edible. In ancient Rome recipes for cooking are given by Apicius, and Pliny’ speaks of their 1 Vilmorin. The Veg. Gard., 1885, 227. 2 Burr.

Cardanus in 1556, says the oblong gourd is edible, and J. Bauhin, in 1651, says the same for two varieties. In India the gourd is said to be eaten, by Drury,‘ Firminger® and others; in China, by Smith; in Cochinchina, by Loureiro;’ in Egypt, by Forskal ;§ in Turkey, by Walsh,’ ete. A variety is in edible use in Japan, as I am informed by Mr. Tamari, and of which I have seen the drawings. In Mexico, a variety, as I am informed by Dr. Edward Palmer, is used to form a preserve known by the name of “ angels’ hairs,” from the fibrous nature of the interior portion which is used. Great-headed Garlic. Alliwm ampeloprasum L. A mild plant, common in the countries bordering on the Medi- terranean, especially in Algeria, and believed to be the native form of the cultivated Leek. In 1568 Camerarius™ speaks of it as cul- tivated in gardens, but this is not confirmed as a common course by the references in the Adversaria, 1570; in Lobel’s observations, 1576 ;*by Dalechamp, in 1587 ; “ by Clusius, 1601 ;* by Dodonzeusy 1616 ;"° these authors referring to it only as a wild plant of the vineyards. In 1882, the Bon Jardinier says the country people of Southern Europe eat it raw, and this is the only known use. It is, however, included among garden esculents by Burr,” in 1863, and by Vilmorin, in 1883. The description which has come down to 1 Albertus Magnus. De Veg., Jessen ed., 1867, 499. ? Cardanus.

Vegetius? calls it the Beticum ulpicum or Andulasian ulpicum. Cato* speaks of its use in veterinary practice. Palladius® gives minute directions for its culture. If, however, cultivated in Italy, it seems not to have extended its area, but to have disappeared in later times, perhaps superseded by the leek, The great-headed garlic is called’in France ail d'orient, ail a cheval, pourrat, pourriole; in Germany, pferde-knoblauch ; in Italy, porrandello, Chabreus, 1677,° gives for names: German, aberlauch, acker- knoblauch; in France, ail pourreau; in Italy, aglioporro.

Thus Parkman! records that Bien-. court and his followers at Port Royal, in 1613, were scattered about the woods and shores digging ground-nuts; and the Pil- grims during their first winter were enforced to live on them. This plant was described and figured by Cornutus? in 1635, and is described by Clayton‘ in 1739. Although probably grown by Cornutus at Paris prior to 1635, yet it received no further atten- tion until again grown in 1849 and should it gain a foot-hold, its introduction would be scored to this latter date. J. Hammond Trumbull thinks the openauk of Hariot,® found in Virginia in 1584, to be this plant, “a kind of root of round form, some of the bigness of walnuts, some far greater, which are found in moist and marish grounds, growing many together one by another in ropes, or as though they were fastened with a string. Being boiled or sodden, they are very good meate.” Brereton,’ in his account of Gosnold’s voyage to New England in 1602, notes the “great store of ground-nuts” found on all the Elizabeth Islands. They grow “ forty together on a string, some of them as big as a hen’s egg.” Champlain, 1605-6, observed that the Indians about Nauset harbor probably had “force des racines qu’els cultivent, lorsquelles ont le gout d’artichaut,” and it is to these roots that Lescarbot® alludes, west and south of Maine, “grosses comme naveux, tres excellentes a manger, ayans un gout retirant aux cardes, mais plus agreable, lesquelles plantus multiplient en telle facon que c’est merveille.”” Kalm," at a later period, 1749, states. that it grows in the meadows along the Delaware, and the roots eaten by the Indians. He adds that the Swedish colonists eat them for want of bread, and that some of the English still eat them instead of potatoes. 1 Pioneers of France, 274. * Young.

The hedgehog or cockscomb sanfoin is called in France herrisson ; in Germany, igel.’ Hop. Humulus lupulus L. As a garden plant the hop is nearly unknown in this country. In Belgium, however, the young shoots of the plant, just as they emerge from the ground, are used as an asparagus, and the plant is enumerated by Vilmorin among kitchen vegetables.” The plant is found in a wild state throughout all Europe, and extends also to the Caucasus, the south Caspian region, and through central and southern Siberia to the Altai mountains, and has been introduced into North Amierica, Brazil and Australia. As a plant for pro- ducing hops to be used in the brewing of beer it has long been in use. Hop gardens are mentioned as existing in France and Ger- many in the eighth and ninth centuries. In America they are - noted in Virginia in 1649, and were among the articles sent the Massachusetts company in 1629." The first allusion that I find to the hop as a kitchen herb is by Cobbett, in 1821, but the use of the young shoots is mentioned by Pliny™ in the first century 1 Winslow.

Horehound. Marrubium vulgare L. This plant affords a popular domestic remedy, and seems in this country to be an inmate of the medicinal herb garden only. In Europe the leaves are sometimes employed as a condiment. Al- though a plant of the old world, it has now secured naturaliza- tion in the New World from Canada to Buenos Ayres and Chili, excepting within the tropics.4 It is figured by Clusius, in 1601, and finds mention by many of the botanists of that period. Horehound is called in France marrube blanc; in Germany, andorn; in Italy, marrubio. Pliny® refers to the Marrubium, among medicinal plants in high esteem, and it finds mention by Columella.” Albertus Mag- nus,’ in the thirteenth century, also refers to its valuable remedial properties in coughs. We may hence believe tha* as a herb of domestic medicine it has accompanied emigrants into all the cooler portions of the globe. Horseradish. Cochlearia armoracia L. This plant cannot be identified with certainty with the Armoracia of the Romans.’ If it be the armoracia of Palladius,” which is a wild plant transferred to the garden, it is very curious that its use 1 Dodonæus.

Zanonius? deems the horseradish to be the draba of Dioscorides. It seems to be the raphanus of Albertus Magnus,’ who lived in the thirteenth century, and he speaks of the plant as wild and domesticated, but its culture then was probably for medi- cinal purposes alone, as indicated by him. Its culture in Italy in 1536 is implied by Ruellius* under the name armoracia, but Castor Durante,’ in 1617, does not describe it. In Germany its culture as a condimental plant is stated by Fuchsius,® in 1542, and by later writers. In 1587 Dalechamp’ states its culture in Germany, but does not mention it in France. Lyte, in 1586, mentions the wild plant, and its uses as a condiment in England, but does not imply culture; but in 1597 Gerarde® states that it is in gardens. It was observed in the gardens of Aleppo by Rauwolf" in 1573-5. It was in American gardens previous to 1806," and is now a plant of market garden culture. Horseradish is a plant of many names. It is called in France raifort sauvage, cran de Bretagne, etc., etc. ; in Germany, Meerretig ; in Flanders, kapucienen mostaard; in Holland, peperwortel; in Denmark, peberrod ; in Italy, rafano : in Spain, taramago, vagisco ; in Portugal, rabao de cavalho; in the north of England, in 1568, red cole, Hyssop.

EDITORS: E. D. COPE AND J. S. KINGSLEY. There can be no “ privileged classes” among scientific workers. As the exact truth is the object of their labors, personal authority does not exist for them except in so far as the reputation of a man for accuracy will sustain his assertions, where the evidence cannot be obtained from the subject-matter itself. It is dangerous for a man holding a superior place in a scientific laboratory or museum to require subscription to his views on the part of his subordinates apart from their conviction of their truth, since if there be error, it is thus all the more widely advertised, and the hostile criticism is the more general. It is dangerous for subordinates to adopt views on the strength of authority alone, unless means of verification are _ Syst. Hort., by J. W, Gent, 1683, 220. Mawe. Gard., 1778. . 434 Editors’ Table. wanting. Nor has science anything to do with national prejudice. There can be no English, no French, and no German schools. Investigation makes all things even, and credit will be awarded to priority wherever the work be done. But there is another kind of . “ privilege” which is more insidious, and against this the real pro- ducers in the scientific field cannot too fully protect themselves. This is the assumption of credit for work not done, by the appli- ances of art and other means at the command of wealth. The scientific pretender who introduces names without definitions, or the wealthy man who publishes pictures, and claims to have made scientific discoveries on the strength of the work of an artist only, may make a considerable popular reputation. The man who in ordinary print only, claims discoveries not his own, is easily disposed of ; but if he fortify himself with new classical expressions or with good pictures, he produces an impression, even among men of science, who are not familiar with the facts. This is espe- cially true of those publishers who can employ good artists. Such is the effect of a pretty picture on the average natu- ralist, that one begins to question whether after all science is not a branch of art, and the true scientists are the artists. Of the value of good illustrations we make no question, but that they can set aside analytical scientific descriptions is a proposition that none but some highly “privileged” person can possibly make, Illustrations on a large scale can be furnished but slowly in some parts of the world, owing to their cost; and in other cases owing to the very large amount of material to be fig- ured. In such cases the scientific results cannot be withheld ; and descriptions without figures will, and, if they are good, ought to precede the illustrated works. To ignore such work is only the part of indolence; and none but “ privileged” persons can afford to be indolent. It has always been the way of this class to enter in and divide the spoil; but science recognizes no proprietary rights. Such persons and their admirers talk grandiloquently of the disinterestedness of the true man of science, and of the sublime indifference to all personal questions which possesses him, But we have always noticed that these very persons resent highly any invasion of their self-assumed privileges; and they are right, m so far as any credit which inheres in them is not granted by others. Scientific, like other men, must live, and their reputation Recent Literature. 435 is the basis of their livelihood. They should then, and in the long run will, refuse to grant especial privileges to either position or wealth, but will expect work to be rewarded by recognition, and will rigorously exclude pretensions based on art or mere nomencla- ture. This they will do as necessary self-preservation, whenever ~ the tendency may be in an opposite direction. We regret to read in our esteemed contemporary, the American Geologist, an editorial apology for what most scientific men disap- prove. We refer to the purchase of the scientific work of a man and the publication of it by the purchaser as though it was his own production. While this kind of a contract is perhaps legal, it is disreputable to the purchaser, A man under necessity for the means of a livelihood may make such a sale of himself without blame; but the man who buys, cannot in this way get a sound scientific reputation. Works of art placed before the public in this way, have been the cause of prosecution of a charge of false pretence against the pseudo-producer. We refer to the Belt case in London, where busts sold as the work of Belt were found to have been purchased by him from the real artist. Belt was mulcted in damages by the court after a trial which attracted much attention. But whatever the law may be, the moral obliquity and intellectual poverty that such a transac- tion implies on the part of the purchaser, are too plain for dispute. RECENT LITERATURE. Baur’s MORPHOGENY OF THE CARPUS AND TARSUS OF THE ERTEBRATA,'— The first portion of Dr. Baur’s work npon the above subject deals with the Batrachia, excluding the Salientia ; e second will treat of the Sauropsida ; the 7 hird of the Mam- malia. The orders of Batrachia accepted are the Ganocephala of Owen ; the Rhachitomi, ype and Ste hala of Cope; the Proteida, Urodela, and Anura, To the Gasiosepiads omer the most ancient of four-footed vertebrates, but Archegosaurus 1 Beit nir Mo h agents des Carpus und Tarsus der Vertebraten, Five oe Ok “Theil, Batractia: Jena, Verlag von Gustav, 436 Recent Literature. alone furnishes data for the elucidation of the subject. Like Eryops this genus has five digits on the fore foot. The incomplete remains of this genus lead to the conclusion that the Ganocephala pos- sesses more elements in both carpus and tarsus than are possessed by any other Batrachians (Salamandrella perhaps excepted), and that the carpus was very similar to the tarsus. To the Stegoceph- ala belong the oldest forms of Batrachia, and in these the number of five digits is already usual. The carpus and tarsus of Necturus each consist of six elements in the adult ; while in Cryptobranchide (Urodela), both in the American and Asiatic species, the carpus has eight, and the tarsus ten elements. The author puts into tabular form the various changes which occur in the number of the ta and carpal bones during growth, and gives examples drawn from all the urodelous families, characterizing each primitive element by a letter or number, and tracing the separations and incorporations of each with its neighbors. ‘These tarsal and carpal tables are followed by a table of the number of the digits in various existing and extinct Batrachia. The rudiment of a sixth digit occurs in the Cryptobranchidz and Amblystomide. Of the three possible modes of origin of the digitated limb (Cheiroterygium): from the fin-form, viz., development from a many-rayed fin; development from a few-rayed fin that has been formed by the obsolescence of the greater part of the rays of a many-rayed fin; and entire sprouting off from a form which had entirely lost its finned extremities. Dr. Baur declares that neither embryology nor palzontology are favorable to the first. All that can be asserted with precision regarding the ancestral form of the Stapedifera is, says our authority, that, since all save strongly mod- ified members of this group have a single bone in the first series of the limbs (humerus, femur), and two bones in the second series (radius, ulna ; tibia, fibula), so the ancestral form must also have had a single ray in the first series, and two rays in the second series. If the two rays of the ancestral form ended each in a single ray, the remaining three digits of the pentadactyle extremity must have been developed by sprouting ; but if the primitive form pos- sessed five digits, the remaining three must represent the last remains of a many-rayed fin. As facts which seem to lend sup- port to the sprouting theory (already advanced by Bruhl) Dr. Baur instances: (1) the secondary division of the rays of the Ichthyop- terygia ; (2) a case of the division of the one-rayed fin of Protop- terus, noticed by Albrecht ; (3) the development and regeneration of the extremities of the Urodela. When the development of the fins of Ceratodus and Protopterus have been studied ; when that of such extremities as normally possess two centralia has been wor out; and when the few-toed extremities of Proteus are fully understood, a great step will have been made towards the solution of the problem. The treatise of Dr. Baur is the most complete Recent Books and Pamphlets. 437 review of the subject yet written, and clears the way for future discoveries.—E, D. ©. CLAUSS ZooLoey.!—The new edition of the “ Lehrbuch” of Dr. Clausis much improved over its predecessors, and it stands to- day the best accessible text-book. The illustrations have been increased in number (there are 792), while much new matter has been incorporated in the pages. As in the first edition, the taxonomy of the Vertebrates remains the poorest portion of the work, American authors have been drawn upon, but it is notice- able that the author does not notice the views of Brooks upon the development of Salpa, while a serious error occurs in the text of the Crustacea where Packard’s term Paleocarida is used for Nebalia instead of Phyllocarida, which Packard gave to the group. Not- withstanding Bateson’s researches, of which no mention is made, Balanoglossus still retains a place near the Echinoderms; in fact, the casual reader would infer from the “make up” that Dr. Claus regarded them as members of the same order as Synapta and Chi- rodota. The price of the volume (18 marks) is quite reasonable in comparison with that charged for the English translation. RECENT BOOKS AND PAMPHLETS. Fewkes, J. W.—A New Mode of Life among Meduse. Ext.

GEOGRAPHY AND TRAVEL.: Asta.—Inpo-Cuina.—M., de Lanessan, in a paper read before the Commercial Geographical Society of France, gives the area of French Indo-China at about 600,000 square kilometres. The Me- kong, though the largest river of the peninsula, passes through a thinly peopled and almost uncultivated region until it enters Cam- bodia. The principal centres above this point are Luang-Praban in the north; Nong-Kay, in the southward bend of the Mekong; Lakhone, in the rear of the Annamite provinces of Hatinh and Nghe-An, and largely colonised by Annamites; Bassac, in a navi- able reach opposite to the mouth of the Se-Moum, which enters abandoned. The Donai is the only river of the region that can entered by large vessels, and a coral bank obstructs even this. The Bay of Touraine, the port of the province of Quang-Nam, so of Hue, is a safe and ample harbor; and that of Ha-Long, in the north of Tonkin, seems to be equal to it. j According to Mr. McCarthy, Superintendent of Surveys in Siam, two spheres of influence, English and Siamese, are prominent In the Malay peninsula. The inhabitants of the northern portion arè Siamese and Chinese, then come the SamSams, a mixture of Malays and Siamese, who are Buddhists and speak a mixed language; then the Malays, who are Mohammedans. There are also two very curious tribes which are supposed to be aboriginal, called by the Malays “Orang Utann,” or wild men, ‘ Edited by W. N. Lockington, Philadelphia, Pa. Geography and Travel. 441 and also known as Sakais and Samangs. The Sakai has soft black skin and wool; the Samang has also a very black skin, but the hair is coarse and straight, and the skin is rough. ey wear no clothes, are clever in snaring fish and game, and use bows and arrows as well as blow-pipes for weapons. Kurpistay.—M. N. Binder recently described his travels in Kurdistan before the French Geographical Society. The name Kurdistan is given by the Turks to a collection of villages in the mountainous district separating Persia from Turkey, between 34° and 40° N. Latitude and 38° and 46° E. Longitude. Lakes Ur- miah and Van are situated in the centre of immense table lands, the former, on account of its small depth and the extreme density of its waters, which are six times more saline than sea-water, does not seem to have a great future before it, but the latter lake offers many advantages. M. N. Binder traced the history of the Kurds, and referred to the current tradition that they have French blood in their veins. The variety of religions is the cause of infinite variety among the tribes. The sedentary and nomadic Kurds differ greatly in occupation and mode of life. The Subbas are a stran sect, with a religion composed of a mixture of gnostic and Chris- as tian ideas. Tae New SIBERIAN Isianps.—A recent number of Peter- mann’s Mitteilungen contains a map of the new Siberian islands, giving the routes of Dr. Bunge, Baron Toll, Captain de Long, N ordenskiéld, etc. The principal islands are Ostrow Blischnij, Kotelnoi, Faddejewskoi, and East New Siberia. North of these lie Bennett Land and Sannikow. Remains of the mammoth, narwhal (probably two species), horse, musk-ox, three kinds of deer, hare and seal were found upon the island of Liachof (Ostrow Blischnij). : THE Hrrrires.—It is probable that the renowned Hittite city Carchemish, is to be sought at the site of Jerablas, from which the identical in shape and position with that worn by the Chinese. he wearers of the pig-tail have Mongolian countenances, and it seems probable that a Mongolian race had obtained the supremacy in some of the Hittite cities, e Nige b rty mako) on July lst, and twelve days later reached Diafarabu. Below 442 General Notes. this point the country was unexplored, forming part of the States. of Tidiani, the chief of Macina. Bandiagara, Tidiani’s capital, is a most important centre of the Mohammedan religion, the town resembling a huge convent. Far- ther down the river it became difficult to get provisions, since the natives had all retired into the interior. On July 9th, Lake Dhe- boë was entered, and was found to receive the river Koli-Koli, which waters the province of Formagha. Below Lake Dheboé the Niger takes the name of Bara Issa, and its banks are thickly lined with populous villages. Tidiani had issued strict orders to the Puls and Bambaras to have no communication with the French. The waters are shallow near Timbuktu, so that the gunboat could not proceed to the town. The djemaa or associations of merchants have been expelled two years before, and a chief named Rhiaia had been installed by the assistance of the Tuaregs. Knowing the per- fidious character of the Tuaregs, the party slept on board every night, and made no excursions into the interior. All negotiations with the chiefs failed, and the Niger returned via the Diaka, or western branch of the river, hitherto unexplored. A vast amount of ethnographical and other valuable information was obtained,. and a detailed survey of this part of the Niger’s course was executed. Bakongo means “a man with a lance,” and thus the river name may be interpreted to mean “ quick as a lance.” J. MENGES JOURNEY SOUTHWARD FROM KassaLa.—J- Menges publishes an account (Petermann’s Mitt.) of his journey between Kassala and the Setit. The very existence of Kassala depends upon the commerce with the countries to the south of it. Two caravan routes conduct sout . One of these follows the Atbara as far as Tomat, and then crosses the steppe to Kedar . The second goes directly from Kassala to the Setit, passing by the imposing granite mountain of Kassala. The people of these regions, belonging to the tribes aaa Dabaina, and Schukpieh, dwell in the dry season on the borders 0 Geography and Travel. . 443- the rivers or in market towns like Kedarif. The character of the three rivers Setit, Atbara and Basalam is everywhere the same; their flood plains are some 90 metres below the barren soil of the plateau, and they are themselves from 120 to 300 metres wide, and about 15 metres deep. AUSTRALIA.—Dr. K. V. Lendenfeld (Petermann’s Mitt., 1888) states that the influence of forests upon the climate of Australia is the reverse of that which they are supposed to exercise in Europe. While European trees retain much of the water among their roots,. the plants of the Australian wastes, including the grasses, Euca- lypti and the Spinifex, send their roots to great depths in search of water, and appear to open their stomata only at night. Dr. Lendenfeld asserts that during his journeys in the interior of New South Wales he has many times travelled all day through forests without seeing grass, The soil, for the most part consist- ing of red loam, is flat and smooth as asphalt, and hard as stone, forming a marked contrast to that of European forests. When it rains in such a forest the greater part of the water runs off into the hollows at once. As many of these water-holes have a subterra- nean communication with the sea, no great lakes are formed. A e greatest river in Australia, the Murray, is navigable only in winter by flat-bottomed steamboats, In many places where squatters have destroyed the forests the bare soil becomes clothed with so many inds of grass as to afford subsistence for a thousand sheep where: a hundred fed previously. Mr. S. Brooke (Petermann’s Mitt., 1888) describes the recent excursion of himself and his brother in Western Australia, and Sives a map of their route. The whole region is lacking in water, yet has numerous plants. The soil is calcareous, with a few moun- tains and granite rocks rising from the plains.

The province of Santa Fe (Argentine Republic), according to the -census of June 8, 1887, now contains 220,332 inhabitants, against 187,000 in 1869. The municipality of Cérdoba, a square of 26 kilometres on each side, contained in October of the same year 66,247 souls, while in 1869 it had but 34,458. Buenos Ayres has now a population of 424,873, and Rosaria 50,914. GEOGRAPHICAL NeEws.—ALGERIA.—The last census (1886) of Algeria gives a population of 3,752,196, being an increase of nearl half a million above the population in 1881. Of this increase 24,209 are Frenchmen, and nearly 22,000 natives of other Euro- ‘pean countries. There has been an influx of more than 17,000 Moroccans into Algeria, while Mohammedan-French subjects have ‘increased from 2,842,497 to 3,264,481. According to Mr. N. J. Dixon, the population of the various States of Colombia is as follows: Boyaca, 483,874; Cauca, 435,- 690; Santander, 423,427; Cundinamarca, 409,602; Antioquia, 365,974; Bolivar, 300,000; Tolima, 230,821; Panama, 220,600 ; -and Magdalena, 85,255; making a total of 2,955,243. GEOLOGY AND PALZONTOLOGY. Norges oN THE ROCKFORD SHALES.—The lithological and paleontological characters of the Rockford shales of Iowa differ -considerably at different localities. or example, the shales which are seen at the south exposure at Owens Grove, Cerro Gordo county, differ conspicuously, in many respects, in their lithological and paleontological characters, from the same beds observed at other localities! The differentiation of the fauna at this place is strongly marked. The three species O Pachyphyllum? which occur at Hackberry and Rockford, are here replaced by a new species of this genus. 1 For a detailed description of the Rockford Shales, and the limestone which immediately underlie them, reference may be made toa paper by the author, on ‘‘Contributions to the Knowledge of the Devonian Fauna of Iowa, with a Description of the Rockford Shales,” now in press by the Davenport Academy of Science. 2 In a paper, now in the hands of the printer, the author has described ‘three new species of this genus. Geology and Paleontology. 445 The species Cystiphyllum davidsonii,!| which occur here in con- siderable numbers, also entirely replace Acervularia inequalis, of other portions of these beds. The Stromatoporoid forms, which. occur at other localities, are here replaced by a single, undetermined species of this genus. Specimens belonging to the following genera are also found here, but are not known to occur elsewhere in the shales. Pleurotomaria, Saxonema, Syringopora, Alveolites, Gyro- ceras, etc. _ In connection with these, we have obtained large numbers of new, and described, species of Lamellibranchs, which do not occur (or if so, in small numbers) elsewhere in this formation. mee ut the chief interest attaches to a certain very large, and undeter- mined species of Trilobite, which occurs here, and entirely replacesall other species of crustaceans which are known to occur at Hackberry and Rockford. e occurrence of this species in these beds is a matter of considerable interest, from the fact that it is the first in- stance of the known occurrence of any of these forms in the Rock- ford shales and indeed, in any of the Devonian rocks of northern owa. The great variation in the lithological and paleontological char- acters of the shales at this place, from those observed at an exposure one and one-fourth miles to the north, as well as those at Hackberry and Rockford, led us at first to doubt their equivalency. But subsequent collections showed a considerable number of typical kford shale species (as shown by the following list), which prove them to be equivalent to other portions of this formation,. as observed at other localities. The following enumeration is that, of some of the typical shale forms occurring here. Spirifera whitneyi, Spirifera hungerfordi, Atrypa hystrix, var. planosuleata Webster, Strophodonta reversa, Strophodonta canace, Campophyllum nanum, Zaphrentis solida, Cystiphyllum mundulum, and Naticopsis gigantea.

Volutions eight to ten or more, very oblique, strongly inflated, most prom- inently so below the centre, rounded.

The depth of the suture in this species is very much greater than the suture in either the foregoing or fol- lowing species.

Position and locality, Rockford Shales, Owens Grove (south exposure), Iowa. Quite a large number of specimens of each of the species described have been secured, and their specific differences are shown to be constant and well marked.—Clement L. Webster, Charles City, Iowa. Some Extinct SCLERODERMS.—In 1887, in the Memorie della Societa Italiana delle Scienze of Naples (3d series, v. 6, No. 4), Baron Achille de Zigno has published descriptions and illustrations of two very interesting Scleroderms from the Eocene beds of Italy. One of these is the Protobalistum imperiale of Massalongo, the other a previously unknown species considered to be congeneric with the ormer and named Protobalistum Omboni; both were obtained from the celebrated Mount Bolca beds. The most casual examination will convince one who has had much experience with recent fishes that the two species have little in common and belong to very dif- ferent genera if not families. Both are, however, important for the light they may throw on the genetic relations and former distribu- tion of the Scleroderms, but each owes its importance to a different reason. The generic description of Protobalistum given by Baron de Zigno is based on the assumption that there are certain characters 1 Duc nuovi pesci fossile della famiglia dei Balistini scopertinel tef- reno eoceno del Veronese. (8 pp., 2 pl) Geology and Paleontology. 447 which are common to the two forms, which does not appear to be justified by the specimens; on the development of 4 to 6 dorsal spines, of spinous rays to each pectoral (“ pectorales radiis duobus spinosis”), and of 1 to 3 spines to each ventral (“ ventrales radiis 1—3 spinosis, retro-flexis’”’). Such features as the last two are so incompatible with the structure of living Scleroderms that the sus- picion is unavoidable that their ascription to the extinct forms is due to some error of observation or interpretation. The principal feature described and corroborated by the illustrations is the num- ber of dorsal spines. The arrangement of the spines is neverthe- less very different in the two species. thidids ; the family name in such case would of course be Proto- balistide. of the back; the first spine is very strong and the others very short; the soft dorsal is elongated, and the anal is oblong; the cau- dal peduncle is well as the structural characteristics (so far as known) of the be to that family, and that it is related to the genera Triacanthodes and Hollardia, with which it agrees in the convex caudal fin, oie the elongated ventral spines. (“Le ventrali sono constituite Delle pettorali non si scorge sull ’esemplare alcuna traccia e delle TAitralo si vede soltanto un Solá raggio pom se lungo tre centimetri piegato all ’indientro lungo il ventre (p. 4). 448 General Notes. name being available for the fossil, it may be named Protacanthodes Hollardia and Triacanthodes in the oblong caudal peduncle and enlarged caudal fin while its physiognomy rather recalls the true Triacanthi. The occurrence of a form so closely related to the Triacanthodes of the Japanese sea, and to the Hollardia of the Caribbean in the eocene seas of Europe, is worthy of special note, and this is a sufficient reason for the present communication. The nearest extinct associate of Protacanthodes is not Protobalis- tum but Acanthopleurus Ag. The two belong to the same family but appear to be otherwise distantly related. The other extinct genera of Scleroderms, Balistomorphus Gill, Acanthoderma Ag. 1843, not Cantraine, 1835, and Bucklandium Koenig— Glyptocephalus Ag.) are rather to be associated with the Balistids. The exact characters and relations of all these fishes remain to be known.— Theo. Gi THE PHYLOGENY OF THE Horsss.'—This brochure of 71 pages, illustrated by two excellent plates, cannot fail to instruct the student who is unfamiliar with this subject. The authoress shows a great degree of familiarity with the history of the facts known in this connection and they are set forth with considerable fulness of detail. She has been more fortunate than some of her predecessors in avoiding record in extenso of the mythology of the subject, which has been long since consigned to its place in the waste-basket by American palzontologists. We allude to the Eohippus, Miohippus, and Pliohippus, which still appear occasionally in theological works and school-books of America and England. A considerable part of the essay is devoted to the endeavor to prove that the genera Palzeotherium and Hippotherium must be excluded from the line of descent, which has continued from Protogonia puercensis through Phenacodus, Hyracotherium, ete., to Equus. he describes and figures with much care certain bones of the carpus and tarsus of Anchitherium, Hippotherium, and Equus, in evidence of this posi- tion as regards Hippotherium. We say with reference to this question, that in discussing the phylogeny of genera, one must confine himself to generic characters, and it is necessary to ascertain what these are in the skeleton before we can use them properly. There are some species of supposed Hippotherium of North Amer- ica which approach Equus so closely in dental characters that the descent of some species of the latter from them looks probable. Probably the species of Equus are polyphyletic,? some coming trom 1 Etudes sur l’Histoire Palzontologique des Ongulés, II, le Developpe ment des Equide. Par Marie Pavlow.

Geology and Paleontology. 449 Hippidium and some from Hippotherium through the intermediate form with the molar teeth of the latter genus, and the single metapodials of the former. This genus has not been named, and I will now call it Hippodactylus, and give as the type Hippotherium antelopinum of Falconer from the Sivalik formation of India. It enters the Equide. We find in this essay two new family names, whose introduction we regret. One of these is the “Hyracotheriide,” which is perhaps a misapprehension of my own Hyracotheriine. This group cannot be separated as a family from the Lophiodontide so far as I can see, The other family name is Pachynolophide. Pachynolophus was based by Pomel on the P. duvali, which is an undoubted mem- ber of the family Lophiodontide, if the figure of Pictet (Traité de Palzontologie) is correct, and 1 believe it to be so after examination of specimens in Paris. But Lydekker and Pavlow place in this genus the Hyracotherium siderotilicwm Pictet, an animal which is not only no Pachynolophus, but is not even a member of the Lophiodontide. Supposing its digits to be 4-3, it will enter the Menodontide, where I have AP it, making it the type of the genus Acoéssus. How many of the species referred to Pachynolo- phus belong to Acoéssus I do not know, but in any case neither genus is a type of a separate family. A further acquaintance with the American literature would have ved some minor errors. Thus it is stated that the limbs of Pro- tohippus have not been described. They were described by me in 1873 (Annual Report U. S. Geolog. Survey Terr.), and were figured by Wortman in the Revue Scientifique, 1883, p. 712, from my blocks, The ancestral relation of Phenacodus to the Dip- larthrous ungulate series, is ascribed to Wortman; but this view was published by the present writer long before that gentleman. The synonym Orotherium is ascribed to Cope instead of to Marsh. Merychippus is not different from Protohippus.—£. D. Cope.

JURASSIC. — The result of the researches of M. L. Dollo into — menace of the Iguanodontide is to prove that Iguanodon nnot be descended from Hypsilophodon or vice versa, but that dey are the types of two utterly distinct families According to Dr. J. V. Deichmiiller, the sabi het of specimens from the lithographic slates now in the Dresden Museum reaches 1680, comprising 114 genera and 193 species, and including 48 species of fishes, 53 of insects, 48 of crustacea, and 21 of cephalo- poda. Among the insects nine forms belong to the Orthoptera, seventeen, besides several still unidentified, to the Neuroptera, six to the Hemiptera, and eighteen to the Coleoptera. Of the Neu- roptera two specimens only are Neuroptera vera, while the Termi- tina are represented by two, and the Ephemeride by one species. The remaining pseudo-neuropterous forms, comprising more than one-third of all the insect specimens, and nearly 95 per cent. of the neuropterous remains, belong to the Odonata. In his “Die Insecten aus dem _ lithographischen Schiefer im Dresdener Museum ” (1886) Dr. Deichmiiller not only gives fuller descrip- tions of previously known forms, but describes two new species of Locustide, one of Notonectidee and one each of Carabide, pay Pes, Scarabeide, Buprestidæ, Elateride, Pyrrochroide, and Chrysomelide. Canozoic.— M. L. Dollo, in his “ Premiére note sur les Chéloniens oligoctnes et néogenes de La Belgique,” reviews the numerous remains of turtles belonging to the group Athece, of which Sphargis is the only existing representative, that has been found in the upper tertiary deposits of Belgium. Remains oe the “ Rupelian ” clay (middle oligocene) were described by P Van Beneden in 1883, under the title of Sphargis rupeliensis while others from the “ Bolderien ” were by the same S alæontologist ‘named Macrochelys scaldii. The discovery of additional material has enabled M. Dollo to ascertain that the Sphargis rupeli M. Van Beneden differs from the recent form by the presence of a continuous bony ventral armor, formed of a mosaic of 8 pee. while S. coriacea has only longitudinal series 0 tubercles; by the slighter convexity of the carapace ; by the Geology and Paleontology. 451 absence of projecting dentellated ridges upon the carapace ; by the margin of the dorsal armor not being rolled downwards; by the greater thickness of the carapace; by the apparent presence of horny plates; and by a skull proportionately shorter, wider, and with thicker bones. The cretaceous genera of the group Athece, viz., Protostega and Protosphargis, were without a dorsal armor. M. L. Dollo concludes that all the fossil Athece yet found in the an =“ a third genus near the former takes the name of Oxyodon- erium. M. Larrazet, as the result of his studies upon the character of the skin among fossil rays, divides them into three types: the first approximating to the modern Raja in form and size; the- second, which has placoid ossifications with a broad base and small Spine, forming the genus Dynatobatis; while the third, the dermal ossifications of which have a long spine and small base, forms the genus Acanthobatis. PLIOCENE AND PLEISTOCENE. — M. A. Villott thus classifies the alluvial deposits of Dauphinè: (1) Those of the high plateaus, some of which occur at a height of 700 metres above sea level, and which may be referred to tertiary times; (2) The pre-glacial deposits of the lower plateaus, forming the upper part of the high terraces, and entirely belonging to the quaternary epoch ; (3) The post-glacial alluvium of the lower terraces, formed after that great extension of the quaternary glaciers. The erosion of the valleys is cela principally to three different periods : (a) that which pre- th ed the quaternary epoch, and was the result of the bursting of © pliocene lakes — a necessary result of the last elevation of the 452 General Notes. Alps; (b) that which occurred during the glacial period; (c) that which is the work of the modern epoch. Four years ago M. G. Rolland announced his belief that the great fresh-water formations of the Sahara are much less recent than had been hitherto believed, the greater portion of them belonging to the pliocene instead of the quaternary age. Subse- quent studies of these deposits have confirmed his first opinion, of which he las now found paleontological proof by the discovery of a number of casts of species of Helix belonging to the group of H. tissoti and semperina, which characterize the lower pliocene of Biskra and Constantine. M. Rolland also shows the synchronism which exists between the different beds of the Eastern Sahara and the corresponding fresh-water beds of the pliocene and quaternary formations in the Atlas region. MINERALOGY AND PETROGRAPHY.' PETROGRAPHICAL NeEws.—Among the rocks gathered by Reyer? during a journey through the Sierra Nevada Mountains, Schuster* has found the following principal types: biotite granites, containing microcline and _pilitized biotite; saussurite-diorite and quartz-diorite, containing orthoclase ; saussurite, pilite, and biotite gabbros ; quartz-porphyrites, kersantites, andesites, serpentine, frag- mental rocks, and tufas. Although the paper in which these rocks are described consists merely of detailed descriptions of detached rock-specimens, it nevertheless contains many points of considerable interest. Pyrophyllite is mentioned as an alteration product 0 olivine and of plagioclase; reaction rims around augite and olivine are pictured; intergrowths of biotite and augite, of biotite and hornblende, and the alteration of biotite into pilite and into horn- blende, are each described. romium mica is mentioned as occur- ring in a magnesite concretion in serpentine ; helminth, as a constit- uent of a diabase porphyrite, and anorthoclase, as existing 10 4 © hornblende porphyrite. A most interesting case of intergrowth 1s that in which a long, tabular crystal of plagioclase penetrates dial- lage in sucha way that its long edges are parallel to the orthopinacoid of the augite, and its twining lamelle are parallel to the lines of inclusions in this mineral. Indications of the effects of pressure were seen in a large number of the sections examined.——V!- Wadsworth‘ has recently published a report embracing preliminary descriptions of the peridotites, gabbros, diabases, and other rocks of 1 Edited by Dr. W.

Some of the larger of the feldspar crystals in this rock show the hour-glass structure frequently seen in augite. The rock of Pietzelstein is a nepheline basalt. Very detailed analyses of specimens of all these rocks are given, and each is very minutely described.——According to Harker,‘ most of the dyke-rocks of the Island Anglesey, off the northwest coast of Wales, are diabases and augite porphyrites. One of these dykes cutting a caleareous shale has converted this rock into a lydianite, in which calcite, clusters of garnet, and anal- ` American Naturalist, 1885, p. 497. i Copper-Bearing Rocks.

Other dykes from the northern portion of the island appear to consist of hornblende and biotite picrites. In one case newly formed, almost colorless hornblende is described as forming a cement between crystals of original hornblende, in a manner analogous to the quartz cement in indurated quartzites. MINERALOGICAL NEws.—The diamonds found in the Province of Minas Geraes, Brazil, are associated with the oxides of titanium, martite, monazite, and xenotine. They are usually found in qua- ternary alluvial deposits, but have their origin, according to Gor- ceix,' in the itacolumites and mica schists which are archean. In these rocks they occur in deposits analogous to those of topaz, ana- tase, rutite, etc. All these minerals occupy well-defined bands in the itacolumite, and are original in it, and are not derived from some older rock, whose detritus supplied the material for the itacolumite and the mica schist. This explanation of the origin of Brazilian diamonds is quite different from that offered? in the case of diamonds of the African and American fields. Polianite, the anhydrous manganese dioxide, has heretofore not been found in sufficiently well-crystallized specimens to admit of a satisfactory determination of its crystallographic constituents. The investiga- tions? seemed to point to an orthorhombic symmetry for it. Messrs. Dana and Penfield‘ have recently proven it to be tetragonal and isomorphous with cassiterite, with a:e==1:.66467. The crystals examined are composite, being composed of several tetragonal indi- viduals which produce a body with an orthorhombic habit.

MIscELLANEOUS.—Cohen! has re-investigated the subject of the pleochroic halos (Höfe) in the biotites of granite and gneiss, and is thereby led to the conclusion that they are produced by the accumu- lation of organic substances in the neighborhood of the inclusions they surround, and are not due to the aggregation of mica mole- cules richer in iron than those forming the, main portion of the mineral in which the halos occur. He finds, contrary to the experience of Lévy,’ that the halos are not affected by treatment with hydrochloric acid, as they should be if they contain a large proportion of iron, but that they are destroyed by heating toa temperature considerably higher than that which is necessary to obliterate the halos in muscovite and cordierite, in which minerals . this phenomena is now generally believed to be due in some way to an organic substance. Franklinite, together with its natural asso- ciate, zincite, has been artificially produced by Gorgeu® by subject- ng to a cherry-red heat an intimate mixture of one part of sodium sulphate, one-half part of zinc sulphate, a quarter to a half part of ferric sulphate, and a little manganese sulphate.‘ BOTANY." are neglected by botanists in general, who seem to have an aversion to all aquatic plants, mainly, it is presumed, from the fact that the collection of aquatics is a specialty. One must go prepared with 456 : General Notes. individuals in America up to recent years; but it is evident that these plants abound in our waters, and that our Chara-flora is varied and strongly characterized. Probably not one-half of the American species have as yet been brought to light, but it is confi- dently anticipated that a better knowledge of their structure and classification will result in a more widespread interest in them. ese plants, often delicate or brittle from an incrustation of lime, are easily destroyed by waves, so that they are rarely found on exposed shores, unless in water deep enough to be beyond the reach of the surface movements. They flourish best in sheltered bays and smaller ponds, especially if a tolerably uniform level of water be maintained. Great changes of level are destructive, alike to species that love the sun and grow in shallow water, and those that hide away in the depths. It is rare, therefore, that Chara- hunting is. profitable in ponds or lakes which feed canals or factories. One prefers the land-locked sheets of water fed by springs, especially if there be a sandy bottom. Temperature has but little influence upon them, though the South has its distinctive species, as well as the North. One species, at least, Chara fragilis, is universal, found in every country and clime, in ice water at the North, and in the hot springs of the Yellowstone, “ hot enough to cook an egg in four minutes.” The best condition of the plant for examination is when it has mature fruit. The time at which this occurs is usually late sum- mer or early fall, though a few species mature early in the spring, and die off in summer. At the South the species are often in g condition the year round, the old fruit holding on, even after new shoots have started from the old nodes. To gather Characee successfully a dredge must be used ; for shallow water a small fine-toothed rake is preferred, but for deeper water (one rarely finds them at a greater depth than ten feet) the dredge and line are essential. The best dredge for all purposes 1s the one recommended by Professor Nordstedt, made as follows : — A disk of lead about three inches in diameter and three-fourths of an inch thick has imbedded in its circumference a row of hooks, about ten in number ; through the centre of this disk is passed an iron rod, which projects about three inches below the disk and about nine inches above; to the ring in the upper end toward which the points of the hooks are directed a cord is attached. The dredge weighs about two and a half pounds, and catches all sorts of “ weeds” growing on the bottom. : The dissection of these plants is perfectly simple. The delicate species are placed in water until their normal form is resto (if they have been dried), and a portion is put in a “cell” on a glass slide and examined under a two-inch objective; sometimes, but rarely, a higher power is needed for determining fine points, such as the structure of the cortex.’ Should the species be incrusted with lime, a piece should be Botany. 457 placed in a little strong vinegar till the lime is completely dissolved, then washed in pure water and examined. Specimens foul with mud must be cleaned in water with a camel’s hair brush, but this is liable to detach the globules of fruit, and is only occasionally to be resorted to. Should it be desirable to preserve bits for future reference, they are best mounted in glycerine-jelly, in “ cells” deep enough to avoid crushing and shal- low enough to permit free examination (flattened brass curtain- rings make excellent cells). When the jelly has dried at the edges, turn on a ring of white zinc cement. — T. F. en, in “ The 2 Characee of America. “ THE FIBRE OF THE BANAaNA.—In a report by the United States Consul, L. J.

This was presented 458 © General Notes. by Dr. Sereno Watson, on March 14, 1888, more than a month after the lamented author’s death, and is entitled “‘ Notes upon some Polypetalous Genera and Orders.” Certain doubtful Rutaceæ are discussed, among them Xanthoxylum, to which correct orthography the author calls particular attention. e notes on Vitaceæ, by way of review of Planchon’s “ Ampel- ideæ,” he had scarcely commenced “when his work upon the Flora of North America ceased.” He pointed out, however, that if we accept Planchon’s numerous genera (see AM. Nat. for March), we must take up Rafinesque’s name, Quinaria, instead of Partheno- cissus for the Virginia Creeper and its relations. Dr. Gray, how- ever, pronounced emphatically against the innovation, maintaining that “the Ampelopsis qunquefolia Michx., remains as the proper representative of the genus, and should preserve the name.” Further he says: “It may still be questioned whether the mass of Ampelides can be definitely separated from Vitis, and into how many genera divided ; but surely Ampelopsis, with the Virginia ` 2) Creeper as the type, must be admitted as a good genus. A New Type or Licens. — Formerly it was supposed that all lichens were ascomycetous, and it was quite a shock when a few years ago the announcement was made of the discovery of certain hymenomycetous lichens. We are now told by Massee (Arch. Sci. Phys. and Nat., xviii.,) of a couple of genera of gastro- mycetous lichens. Thus we have now known the following roups of lichens: (1) Ascolichenes, (2) Hymenolichenes, and (3) astrolichenes. Tue ASH oF TILLANDSIA USNEOIDES.—This plant, popularly known as the Florida long-moss, is considered as a typical epiphyte- Reliable observers have stated that it will grow and increase, month by month, on a support as juiceless as a telegraph wire. Its roots are looked upon as mere hold-fasts—anchors, to prevent the plant from falling to the earth. No absorption is supposed to take place through those roots; thus the plant is considered to differ from arasitic species like Phoradendron, etc. Yet it is well known that this so-called epiphyte has a certain proportion of mineral matter in its make-up. At the suggestion of Professor Henry Trimble, I have made an analysis of this ash, and have found the composition of it to be full of interest. If the roots do not absorb the joie of the supporting trees, then this mineral matter found in the plant must be collected from the air. It is hardly to be supposed that the floating dust of the forests where the Tillandsia grows 18 V abundant; and it seems almost absurd to think that all the ele- ments found in the ash can have been collected in this way. following are the results obtained from about 100 grammes of the dried plant. The moss was in a green condition when receiv Total ash, 2.95 per cent. Composition :— ; Botany. 459 Silica 10.300 per cent. Ferric oxide 2.100 per cent.

Chlorine 6.947 per cent.. Carbonie acid 12.900 per cent. Phosphorie acid + 93.034 per cent. 99.638 But one other analysis of this ash has been found by me;. that of Avequin,' in 1835, which is recorded in the following way (in effect, as I have not the exact language at hand) :— Osten grammes of dry plant gave 32.35 grammes of ash, composed Salts of potash (phosphate, sulphate, carbonate ande ide) : ) 11.47 gr. Lime (partly as carbonate) 5.96 gr. Phosphates of lime and magnesia 9.26 gr. Silica containing a little iron and manganese...... 5.66 gr. 32.35 It will be observed that the total ash (3.235 per cent.) is nearly the same as that obtained by me. If the iron and alumina, as well as the manganese, in my analysis, are added to the silica, the sum 1s 16.672 per cent., which is not greatly different from the impure silica of Avequin, 17.186 per cent. It would therefore appear that the plant must uniformly have some such ash as that found above. (Indeed, the ash of any one plant, as is well known does not vary greatly.) What, then, shall we think? That the roots do absorb the characteristic ash-constituents from the trees on which they grow? That would seem to me more rational than to suppose them to be absorbed from the floating matter of the air. But if we do arrive at this conclusion, our idea of the term epiphyte must certainly undergo a radical change—T, Chalkley Palmer. Tue Errecr on VEGETATION OF THE VARIABLE RAIN- FALL OF NORTHWESTERN Mexico.2—First, want of water. Those who have travelled over the northwestern portion of Mexico Will, I think, agree with the writer that it is a dry, barren section, and in want of water. Rains are very uncertain, often years passing Without a shower sufficient to cause a good growth of vegetation. When the first white settlers made their homes in this region, over two hundred years ago, they did so during a very dry period of several months, during which they formed the conclusion that th * Journal de i : sn, Read before the Botanical section of the Biological Society of Wash- ington, March 7, 1888, -460 General Notes. region was one in which it never rained. Their effort, therefore, was to do without rain. The settlements were made near springs or streams, both of which were few, and consequently the settle- ments limited. During the thirty-two months previous to last August enough rain had not fallen to produce vegetation of suffi- ‘cient length to be cut for hay. e appearance of the country ‘during the dry season is that of a waste, destitute of food for man or beast, except in favored spots along the creeks and springs; and if nature did not endow some of the plants with power to bloom and mature their fruits during different periods of the year, this desert country would be still more uninviting. The various numbers of the Cactus family produce their showy and attractive flowers dur- ing the dry season, these being followed by the sweet, juicy and nutritious fruit, during the hottest part of the year, about the last -of June. There are some forms of the Leguminosre which also bloom and mature fruit during the dry period when there are no leaves upon ‘them. ese plants which bloom and fruit during the dry sea- son, though but a small portion of the whole, contrast very agree- ‘ably with the pinched, withered, and resting plants that surround them. What adds still more to the desert appearance of the country at this season of the year is the character of the soil; the hills and mountains, which are very rocky, have now put on their sombrest, reddish brown, and not a vestige of green is observed upon their surface. A stranger coming into the country during the dry season would ask the question, “ When or how often does it rain?” A nist desiring to make a collection can only gather the plants that bloom during the dry season, and must wait for the rain in order to com- plete his colleetion. One serious effect of the insufficient rains 18 seen when the shrubs and annuals start into growth after a shower, only to be killed or fail of maturity during the subsequent drought. The second cause of the scanty vegetation of this region 15 excess of water. The violent rains and water-spouts which occa- sionally occur are exceedingly destructive. In 1717 there was a great rainfall, and those people who had come to the belief that it never rained there, and had only pro- vided themselves with the cheapest and easiest contrivances 1n which to live, found that it did rain— for forty-six hours 4t rained so excessively that it destroyed nearly all the food the in- habitants had. The churches and other buildings of the mission- aries were leveled to the ground, they being of unburnt brick, ared for planting; rains prepared. | Zoology. 46F Not far from Guaymas is a small village, celebrated for its. gardens. A few years ago this place was devastated by hea rains; many houses were carried away, some gardens greatly injured and others entirely obliterated. Where once there were gardens is now a large area covered with rocks, gravel and sand, resembling a dry river bed. The inhabitants point out to you many localities once fertile, now barren in consequence of excessive- rains. Last summer a waterspout fell in the village of Molage in Lower California. The village is built on the brow of a range of low rocky hills, in front of which runs a small stream used to water the gardens upon either side. So sudden and great was the- fall of water that before the inhabitants were aware of it the flood was upon them and many houses swept away, the people having: barely time to escape with their lives. After the waters had sub- sided, the valley which had been filled with gardens and green: fields presented a rocky waste, as barren as the adjoining hills upon which no rain had this year fallen. While travelling in this part of Mexico last autumn my attention was frequently called to spots injured by the fall of waterspouts. In a country with so little- land suitable for cultivation, the loss of however little is severely felt by the inhabitants. The period which is considered the rainy season lasts from July- to December. In one place the rains may commence in one month,. in another place some other month, and no two places, however near, are likely to have the same amount. For example, about uaymas last season the rainy season commenced in the middle of August and ended about the first of October, during which four good rains fell, while at Angel’s Bay in Lower California, the first rains were a shower in the early part of November and another- about the first of December. After this vegetation quickly sprang up and into bloom, so that at the time of my visit the place looked like spring, while at the same period the vegetation about Guaymas,. only two hundred miles distant, had come to maturity. — Dr.. Edward Palmer.» ZOOLOGY. KIDNEY 1N Sra-Urcurns.—The brothers Sarasin (Zool. An- zeger, 227) claim that the brown structure which surrounds the stone canal of the sea urchins, and to which numberless functions have ae n ascribed, is in reality a nephridial apparatus. In Asthenosoma cells which resemble those of renal organs, and notably those of the 462 General Notes. Molluses. These glandular pouches empty into the main lumen by narrow ducts, while delicate canals, following a contorted. course, extend to the periphery of the organ and terminate by ciliated fun- nels in the body cavity ina manner which recalls the nephrostomes of segmented animals. The excretory duct runs towards the aboral surface, and beneath the stone canal forms a narrow duct, both stone canal and ureter uniting in a common collecting vescicle which empties through the madreporic canals. : Lire History or Harr-Worms.—In a recent paper on the hair worms L. Camerano discusses several points in connection with these forms. He thinks that the same species may occur in differ- ent hosts, the filiform condition being found only in insects. Man may be occasionally a host for some of the laryal stages. The cycle of the individual is as follows: The eggs, which are laid freely in the water, hatch out larvee which swim freely and then obtain en- trance to a host when they become encysted and undergo a meta- morphosis. The metamorphosis results in the young, filiform larve which grows directly into the adult, with sexual organs developed. This lives freely in the water where copulation takes place and the eggs are laid. Some strictures upon the account given by Camer- ano may be found in the Zoologisches Anzeiger for 1888, p. 70. Villot there states that some of Camerano’s species are in reality immature forms. THE ORIGIN OF SEGMENTAL Oreans.—M. F. E. Beddard (Q. J. M.S., 1888) discusses the structure of the nephridia in Acan- thodrilus and Perichæta. In each of these genera there are several segmental organs to each segment, there being in Acanthodrilus over a hundred apertures in a segment. The glandular part of the system varies much from the typical condition of nephridia in other respects. In Acanthodrilus the inner openings of the tuft-like nephridia were not found, while the excretory ducts of the eight or more organs in each segment were branched, each branch communi- cating with a nephridiopore. In Perichæta the case is even more complicated. The tubules were not observed to branch in the body wall, but in the body cavity the nephridial system forms a con- tinuous,network passing through the dissepiments from one seg- ment to another, while the systems of the right and left side of the body also communicate with each other. Internal funnels were not found. Beddard reviews the opinions advanced by various natural- ists as to the phylogemy of the nephridial system of the anneli and thinks that the new facts which he adduces favor the view that the annelid excretory system is directly traceable to that of the Plathelminthes. He, however, differs from Lang in his theory that he does not regard the longitudinal duct of many annelids as 1n any way homologous with that of the Plathelminthes, but, m the light of Wilson’s researches, as an entirely different structure. Zoology. 463 BRANCHIAL EYES or BRANCHIOMMA.—Branchiomma is à genus of Sabillid worms remarkable for possessing eyes on the tips of its gills. C. Brunotte (Comptes Rendus, 1888, p. 301) has re- cently described the structure of these, arriving at the following conclusions. They are to be regarded as a new type of compound eye formed of two layers, an outer dioptric and an inner sensory. The outer surface is facetted and beneath each facet is found a small spherical lens situated above a rounded cavity which is filled with a large nucleated cell, and behind this is an elongated refractive body connected with terminations of the optic nerve. This part of the eye is without pigment. PHOSPHORESCENT ORGANS OF THysaNopopa.—R. Vallentin and J. T. Cunningham discuss the structure and functions of the phosphorescent organs of Thysanopoda (Nyctiphanes) norvegica in the February number of the Quart. Jour. Micros. Science. These crustacea have long been known to have eye-like organs upon the sides of the body and in the median line,—organs which were uni- versally regarded as accessory eyes until the present decade. There are ten of these organs, their distribution being pretty uniform in all the genera of the family Euphauside to which Thysanopoda belongs. All of these organs except those on the peduncles of the eyes have the same structure. Behind the organ is bounded by a layer of wavy lamine forming a hemispherical unperforated cup open in front. This is compared to the reflector described by von Lendenfeld in Fishes (vide Amer. Nat. xxii.). This reflector is lined internally with red mesodermic pigment-cells, and their in- terior are lined by a layer of large columnar cells, inside of which 1S a curious fibrillar structure which surrounds the inner half of the lconvex lens, Outside the lens occur a circular cornea follow y the ordinary epidermis and the usual cuticle.

Edinb., ix.) after a historical résumé of the results of others, details the results of his own obser- vations on the reproduction of lost legs and antenne in three lob- sters which he kept in confinement. He concludes that in the lobster at least—contrary to Reaumur—the new appendage, which is formed beneath a thin pellicle soon after the loss, is only set free at the time of molting. The antennal rudiment is at first conical, then becomes coiled in a spiral, and at the first molt this is set free, but the normal size is not reached until three or four molts. The large claws also required a similar period, becoming as large as their fellow. In one instance the right claw was lost when the pincer of the left side was three inches long. At the next molt the new right pincer was 23 inches long, while its fellow had increased to 3% inches; at the second molt the difference between them was reduced to 4 inch, while the third molt reduced the disparity to } inch. The ambulatory limbs, on the contrary, regain their full size in a single molt, an observation at variance with Chantran’s account of the reproduction of lost parts in Astacus. THE OssicuLA AUDITUS OF THE BATRACHIA.—The follow- ing is an abstract of a paper read before the United States National Academy of Sciences at its meeting in Washington on April 18th, 1888. The conclusions reached are the following: as to the origin of the genus Siren. This is to the effect that Siren is an animal which is descended from a land salamander, and its immediate ancestor became aquatic again at a comparatively late period of geological time. My opinion was at first suggested by the condition of the branchie in very young animals, where they are functionally abortive, and do not become respiratory organs uD later in life, the largest animals having the best developed gills. The characters of the stapes confirm this view, since they are those of land salamanders, as distinguished from those of aquatic habitat. Secondly.—There are three types of relation between the cera- tohyal arch and the skull. In the one there is no connection be- tween the two, as in the Pseudophidia. Secondly the connection 18 ligamentous. This is seen in Proteida, Trachystomata, and all Pseu- dosauria except the Amblystomide and Plethodontide. The last two 1 American Naturalist, 1885, p. 1226. Zoology. 465 families embrace the third type, in which the ceratohyal is articu- lated by suture with the quadrate. This last type is the most spe- cialized, since the larve of those families display the connection be- tween the ceratohyal and the skull similar to that seen in the ty second. Thus the Salamandride, which are superior to the Pletho- dontidz in their osseus carpus and tarsus and opisthoccelous verte- bre, have the hyoid connected with the skull as in the larve of the atter. Third.—At a stage in the history of the development of the Sa- lientia, the relations of the stapes and of the ceratohyal to the skull are the same asin a transitional stage of the Urodele family of Plethodontide. Or taken Separately, the relations of the stapes are those of Proteida, Trematodera, and larval Pseudosauria, while the relation of the ceratohyal is as in adult Plethodontide and Amblys- tomidæ. This is when the interstapedial cartilage connects the stapes with the posterior face of the quadrate cartilage, and when the ceratohyal articulates with the posterior face of the quadrate at its distal part. Fourth—lIt is not probable that the epistapedial forms an inte- gral part of a primitive element representing the ossicula auditus, as it originates independently of the interstapedial and mesostapedial. _ Fijth—The interstapedial and mesostapedial do not at any time ìn the history of the development of the genus Rana form any part of the ceratohyal or Meckelian ventral arches. As the incus and malleus of the mammalian ossicula auditus are segmented from the proximal parts of these arches, embryology indicates that they are not homologous with the ossicula of the Salientia. From this point of view the latter form a special line of development, distinct from that displayed by the Mammalia, unless the developmental reco as been greatly falsified by cenogeny. From the embryological standpoint it follows that the ossicula auditus of the Batrachia Sa- lientia must be excluded from the discussion of the homologies of the mammalian ossicula. Sizth.—But the characters of the Ganocephala and Rhachitomi permit the following reflections, since the latter order is the one from which the Salientia derived their descent. The existence of a well-developed columella auris which is unsegmented, in the for- mer orders, apparently like that of the Lacertilia, suggest that segmentation seen in the Salientia is a specialization of later origin. This columella has also the position of the proximal part of the ceratohyal in the adult frog and the larval salamander. As the position of this element in all but the youngest tadpoles is a result or Cenogeny, it may be inferred that the ossicula auditus of both the Rhachitomi and the Salientia represent the separated proximal = of that arch, and hence be truly homologous with the incus of ae mammal. The probability that this is the case is increased by p er of this element in the Pelycosaurian genus Clep- sydrops' where the columella extends to the cranial wall, leaving *See Proceed. Amer. Philosoph. Society, 1884, p. 41, Pl. 466 General Notes. the stapes to one side. This is exactly comparable to the relation — between the interstapedial and the stapes seen in the Sa lientia, ex- cept that the two elements are not actually connected as in Clepsy- drops. Paleontology then modifies the evidence from embryology, and renders it highly probable that the columella auris, interstape- dial and incus are homologous elements, and originated by segmen- tation from the proximal end of a ventral cranial arch, probably the _ ceratohyal. Seventh.—It follows, from what has preceded, that the condition of the representatives of the ossicula aiditus in the Urodela is one of a. Highth.—It becomes probable, but not certain, from the position of the spilt disc in the Rhachitomi at the proximal base of the quadrate bone, that the epistapedial cartilage has originated asa segmentation from the proximal extremity of the quadrate cartilage, ‘and is therefore truly homologous with the mammalian malleus.

Anzeiger, 1888) points out that the Monitoride are in several features widely separated from the other Lacertilia, and that the same peculiarities tend to ally them to the Crocodiles. Among the points discovered by other naturalists he mentions the arrangement and development of the teeth, the complicated network formed by the hepatic and cystic ducts, and the arrangement of the blood ves- sels of the neck. The new features are: On cutting through the abdominal wall the viscera are not at once brought into view, as they are enveloped by a fold of the peritoneum which forms a closed sac completely separating the abdominal viscera from the heart and lungs. This feature is compared to a similar structure described by all students of crocodilian anatomy. Huxley com- pares this last with the oblique septum of the bird, but Beddard thinks it equivalent to the septum and to the so-called omentum as well and at the same time but an exaggeration of the structure occurring in the Monitors. If his points are well made (that the Monitors are not closely allied to the other Lacertilia but rather to the Crocodilia) Beddard thinks that the ancestry of the Crocodiles must be sought in the direction of the Monitoride. A Cow Witn Oxe Kipney.—I lately saw butchered a healthy cow which had but one kidney, the right one.

General Notes. ENTOMOLOGY. A LABORATORY OF Ex INTAL ENTOMOLOGY.— Reference has already been made in these Notes (Ante, p. 261) to a probable increase in entomological investigations, due to the establishment by the United States Government ofan agricultural experiment station in each of the States, in connection with the agricultural colleges. The New York Station has been organized at Cornell University. Provision has been made here for experiments in gen- eral agriculture, chemistry, veterinary science, botany, entomology, and horticulture. The Station Council has been very liberal in its provisions for experiments in entomology. A separate building for this purpose is being erected, and provision has been made for thoroughly equipping it. As this building is novel, both as regards its structure and the purpose for which it is intended, a brief account of it may be of interest. It consists of two parts—a laboratory building and a vivary. The former is a two-story cottage, containing a laboratory for the experimenter and his artist, a shop and laboratory for an assistant, a room for photographic work, quarters for a janitor, store-room and basement. The vivary is in the form of an ordinary botanical conservatory, sixty feet in length. This is divided by a transverse partition into two rooms of equal size. One of these is to be used asa hot-house; the other is to be kept as nearly as pos- sible at the temperature ofthe outside air. The purpose of this vivary is to enable the experimenter to keep the insects that he is studying alive upon growing plants and to conduct experiments with insecticides, where all of the conditions can be controlled. Especial apparatus for carrying on this work has been devised and is being constructed. One of these devices is an arrangement by means of which insects living upon roots of plants can be observed continuously without disturbing them. Another is intended to aid in the study of the relations that exist between ants and plant-lice. Others are for experiments in the use of insecticides. Descriptions of some © these devices will be published later.—J. H. Comstock. Aquatic LEPIDOPTEROUS Lary ®.—A number of instances are on record of Lepidopterous larvee that normally descend beneath the surface of water in order to feed upon submerged plants. The best- known of these in this country is the species of Argama that infest the leaf-stalks of pond-lilies. The habits of this insect were described by the writer several years ago.’ Although these insects 5 is edite J.

Entomology. 469 spend a large part of the time in water, they are obliged to come to the surface at intervals for a supply of fresh air. There are, however, a few Lepidopterous larve that are truly aquatic. One was described by Baron de Geer more than one hundred years ago.' This is the European Paraponyz stratiotalis. Another was described in 1884 by Wilh. Miiller-Blumenau.? This is a Brazilian insect, Cataclysta pyropalis, which, like the preceding, belongs to the family Pyralide. We have just received an account of a third species, which is described by J. Wood-Mason in a small pamphlet, entitled Report on the Paraponyx oryzalis, an Insect-pest of the Rice-Plant in Burma, This pamphlet was published in Calcutta in 1885. The insect described in it is supposed to be a congener of the European species referred to above, although only the larva and pupa have been described. The caterpillar is about seven millimetres in length and is abundantly supplied with tracheal gills. These are in the form of filaments, arranged in little bundles or tufts. There are four longitudinal rows of these tufts, extending nearly from one end of the body to the other; that is, two rows on each side of the ody —one above the spiracles, the other below them. : THE ORTHOPTERA oF New ENGLAND.—Professor Fernald has Just published a manual of the Orthoptera of New England, in which all the species found in that section are carefully described. Analytical keys are given for the determination of families, sub- families, and genera, and, wherever necessary, there are tables of Species. The work is an important addition to the series of hand- books prepared by this author. It will do much towards popular- izing a knowledge of this very important order of insects.

EMBRYOLOGY or [Nsects AND ARACHNIDs.’—Under this title, the friends of the author have issued the results of studies made by the late Dr. Adam Todd Bruce upon the embryology of Thyridop- teryx, Chrysopa, Meloe, Mantis, the Grasshopper, Musca, and an undetermined spider. The most, complete observations were made upon the development of Thyridopteryx, where Dr. Bruce failed to find the centrolicithal segmentation described as characteristic of arthropod embryology, but rather a central segmentation, the blas- em from the lateral thickenings. The maxille in the embryo are triramose. In the fly, observations were recorded on the development of the _ egg and its maturation, Dr. Bruce regarding the yolk as arising from the breaking down of the epithelium of the outer end of the ovarian tube. : In the spider, Dr. Bruce found the invagination for the optic vescicles (vide PI. vi., Figs. lxxx and lxxxi.) ; but he erred in calling it the amniotic fold, otherwise (as he published a preliminary ere in which this fold was mentioned) he might have anticipated Locy in his discovery. Some observations are recorded upon the forma- tion of the pulmonary organs, but, from reasons not apparent 1n either figures or text, the author thinks that two appendages are concerned in the formation of each lung-book. It is, however, to be noted that his observations, so far as they go, show that the lung- books are in reality modified appendages, and support the hypo- 1 Edited by Prof. Jno. A.

Among the conclusions which are drawn, the following are worthy of note. The yolk-cells of hexapods and spiders are regarded as the true endoderm, but their purpose is the digestion of the yolk. The functional endoderm is of later origin, and forms the epithelium of the digestive tract. Spiders and the Merostomata are allied to each other, and differ from other arthropods in the absence of antenne. The tracheæ of hexapods and of spiders are not homolo- gous ; for in the one they are clearly modified appendages, while in the other they occur on segments where well-marked appendages exist.—J. S. K. THE DEVELOPMENT OF CrANGON.—In continuing my studies of the ontogeny of Crangon, I find the following points worthy of presentation, apart from my complete paper, soon to be issued. The blastopore, contrary to my previous statement, never becomes com- pletely obliterated, but persists, and later an in-pushing takes place from the same spot and gives rise to the proctodeum. he anus is at first dorsal in position, and attains its ventral position later by an outgrowth of the telson. In front of the anus are a number of large budding-cells, both ectodermal and mesodermal, and from these are budded off new cells, which give origin to the segments of the body. They con- tribute largely to the nervous system and myotomes, and in them occur the only cases I have seen of karyokinesis in Crangon. They may be compared with the mesoblasts and neuroblasts of the leech, as described by Dr. Whitman. | The alimentary tract proper is wholly of ectodermal origin, the proctodeal` and stomodeal inpushings, giving rise to all of it. The endoderm of invagination forms first migratory yolk- cells, which metabolise the yolk, and, later, arrange themselves — = epithelium of the so-called “liver” or mid-gut gland of renzel, The green gland is of mesodermal origin, as maintained by Grobben, and not of ectodermal, as described by Reichenbach and Ishikawa. This allows of its comparison with the segmental organs of the annelids. These points will be fully illustrated in the complete paper.—J. S. Kingsley, Bloomington, Ind. 472 General Notes. PHYSIOLOGY .! NOTES ON THE PREPARATION OF NUTRIENT GELATINE AND AGaAr.—The practical worker in Bacteriology deplores the loss of time usually attendant upon the preparation, and especially upon the filtration of nutrient gelatine and agar. The method formulated by Koch and closely followed by most workers, is very satisfactory in producing good, clear culture media, but a few modifications render the procedure a much less formidable one, and as the changes to be suggested are simply those of detail, it may be well to state in brief the method now in use in this laboratory, which after consid- erable trial gives uniform and satisfactory results. One pound (4 kg.) of finely chopped beef, as free as possible from fat and gristle, is mixed with 1000 c. c. of distilled water and kept in a cool place for 12 or 18 hours. It is then strained, cold, through a coarse cloth, into a wide-mouthed “agate ware” or “enameled iron” vessel of sufficient size, and 5 gm. of C. P. so- dium chloride, 10 gm. of pepton,! and 100 gm. of gelatine’ (or 10 gm. of Agar) are added. This is then placed in a water bath’ (to which a large handful of rock salt has been added, if agar is to be prepared) and the gelatine (or agar) melted as rapidly as possible. The fluid is then neutralized by the careful addition of sodium bicarbonate in solution, and the boiling continued for a few minutes after, in order to precipitate the phosphates. The fluid is now cooled by running water, to such a temperature as will not coagulate the white of egg, yet not enough to solidify it, when the whites of two eggs, thoroughly beaten up are mixed with it, and the whole boiled for half an hour. Filtration which has usually been effected by means of filter pa- per, can be much more rapidly performed by the use of absorbent cot- ton in large quantity. The pores of the paper become clogged by the fine precipitates and by the cooling of the medium, and even with the use of the “hot funnel ” the filtration is sometimes very slow. Cotton, on the other hand, presents in its meshes a much larger surface for the entanglement of the fine precipitates, and when used in large quantity, allows the gelatine (or agar) even when not very hot, to flow through it rapidly. The preparation of the filter is as follows: The absorbent cotton is unrolled, and sterilized in bulk in the hot-air chamber, care being taken not to char it.

Hesterberg, Berlin, is used, aS imparts no color. ‘The form that has been found most convenient is known as AN agate ware ‘‘ Milk or Rice boiler.” Physiology. 473 (15 ctm.) glass funnel is packed full with the dry sterilized cotton, placed in in layers, in such a way as to keep it well out of the neck, and having no folds nor ridges of cotton next the glass, through which the precipitates might pass into the receivin k. The neutralized culture medium, after being boiled with the white of egg, as above described, is strained through coarse flan- nel into a flask, and poured slowly upon the centre of the filter until the cotton is thoroughly soaked, and the fluid begins to run into the flask below. This moistening causes the cotton to sink consider- ably, and packs it in the funnel, and when packed, the fluid filters through it almost as rapidly as it is poured into the funnel. The funnel is now filled and the fluid filtered as fastas it will run through. The first filtration seldom produces a clear medium, but through the same filter the fluid may be poured again and again, each time becoming clearer, and the moderate cooling which neces- sarily occurs, does not sensibly retard the rapidity of filtration. When filtration is completed, a considerable portion of thè medium entangled in the filter can be saved, by pressing upon the cotton with a sterilized glass rod, gently at first and near the sides, then in the centre and with considerable force. The gelatine or agar pressed from the cotton is sometimes cloudy, for which reason it is well to catch it in a separate flask. _ It not infrequently happens that gelatine which filters clear pre- Cipitates phosphates on boiling; and that agar, on cooling, forms a occulent precipitate. To insure against filling tubes with such media, it is safest always to fill one tube with the medium, and by first cooling, then by boiling and again cooling, to test the perma- nence of the transparency obtained. Should these precipitates form, it will be necessary to boil the gelatine in the flask, and to refilter it through a small plug of dry cotton placed in a funnel; while agar should be allowed to completely solidify, when it is again melted and filtered through a small plug of cotton, The media are now ready for tubing and sterilizing in the usual way. he large quantity of absorbent cotton used and the considerable amount of medium lost, by remaining entangled in the meshes o the cotton (this may amount to 200 c. ¢. for each of the large cotton filters employed) are unquestionably objections to this method of filtration, but in its favor it may be stated that one filter when properly packed, serves to clear a large quantity of medium, and the great saving of time in filtering, enables one to prepare a large amount of these nutrients at one operation, which may be stored or future use. Futhermore, the “ hot funnel ” is dispensed with. The modifications here described may be best appreciated by — the fact that they render it possible to prepare within three hours Several litres of the above-mentioned culture media.—T. M.

THE Monkey AS A SCIENTIFIC INVESTIGATOR.—In the very interesting little “ zoo,” which now forms quite an attractive depart- ment of the National Museum at Washington, there is a fine male grivet monkey (Cercopithecus erythræa), who shares a large cage with four opossums. Although he has a bad record as a fighter and biter of human beings, he takes kindly to his strange compan- ions, and they have been the best of friends from the first. He spends many an hour in searching the fur of the opossums, and always sleeps with them in the family bed of straw. A few days ago the attention of the attendant was drawn to the monkey cage by the excited behavior of the crowd in front of it, and on going to ascertain the cause a strange and ludicrous sight was revealed to his astonished gaze. In the middle of the cage sat the monkey, holding one of the opossums in his lap, with her belly uppermost, and her head under is arm. She submitted quite passively, far more so than when the attendants had previously made a similar examination. The monkey had just discovered the marsupial pouch of the opossum, and was diligently investigating it. ad he not been a close observer it certainly would have remained unseen, for it was s0 tightly closed as to be perfectly invisible in its normal condition. The monkey carefully lifted the outer wall of the pouch, and pee into the cavity. Then he reached in with his hand, felt about for a moment, and to the astonishment of everybody took out a tiny young opossum, about two inches long, hairless, blind, and very helpless, but alive and kicking. Jock held it up to the light, where he could get a good view of it, scrutinized it with the air of a savant, and presently returned it to the pouch, very carefully. After replacing it he looked into the pouch again, and presently drew out another for examination, which he looked at with solemn interest, smelled of it, and then carefully put it back. It was thus it became known to the attendants that the old female opossum had the young ones, which had previously been looked for in vaim. — W. T. Hornaday. Archeology and Anthropology. 475 ARCHEOLOGY AND ANTHROPOLOGY. The Anthropological Society of Washington held its 138th regular meeting May Ist. Mr. W. H. Holmes, who has divided his talents about equally between science and art and been success- ful in both, read a paper entitled “Some Primitive Phases of 4Esthetic Development.” He directed his remarks principally to art in American prehistoric pottery. He said these earthen vessels were the outgrowth of natural form, finally acquiring decoration. This pottery was originally moulded in a basket or wicker-work (having the appropriate shape), thus giving to the soft clay the impressions of the woven meshes. When the vessel was burned these formed the decoration. This method of decoration seems to have been afterwards replaced by another, in which the cloth or wicker-work was either wrapped about or its figure cut into a wooden mould or form which was pressed on the outside of the vessel. A notched wheel was sometimes us me of the decorated vessels were shown, as well as some of the paddles used. These were, however, ull modern Indian work. Another paper was by Dr. W. J. Hoffman, on “ Pictography and Shamanistie Rites of the Ojibwa.” This tribe Lage s to Minnesota. It has three distinct secret societies. The Grand are four degrees. The rites occur in the spring, and the winter months are passed in study and preparation for t i longing life. Those who take but one degree usually manufacture the fetishes. Dr, Hoffman presented a number of original charts, hot the sacred ones, from this tribe, showing the use of the charac- ters, their meaning, and the method of translation. He also exhibited enlarged copies of charts which he had copied, sometimes Surreptitiously, while among these Indians. i Guasro is, according to Dr. A. Ernst, of Carácas, the correct orm of the name of the Guajiro Indians inhabiting the South American peninsula called after them.

Before this, Rafael Celedon, director of the seminary at -Santa Marta, wrote a grammar of the language, which was pub- lished by E. Uricoechea in Maisonneuve & Co.’s Linguistic Collec- tion, Paris, 1888. In an appendix to that treatise, Uricoechea reproduced Ernst’s vocabulary of Guajiro without giving credit to the author for it. Celedon’s work was regarded as insufficient in several respects by Don Jorge Isaacs, who published his critical remarks and strictures in the Estudio del lenguaje Guajiro” Ernst regards that treatise as a valuable contribution to the knowledge of these South American dialects. Celedon, however, asserted his position, and defended himself against Isaacs’s strictures in another article of the same Anales, entitled Gramatica Guajira, 1887, pp. 491-515. It seems to us that these attacks were victoriously ‘warded off in part, and no student of that language must fail to read the writings of both antagonists. Both are placing the Guajiro language among the Carib dialects, to which it undoubtedly belongs. Ernst himself expresses the opinion “ that this tribe forms a fragment -of the scattered Arrowak, or Aruak ethnic family, linguistically as well as anthropologically:” He states that the word Guajiro also occurs on the island of Cuba, the farmers being called by this name there from guayu, we (in Arawak wáyu) in the Guajiro language. It is impossible to make a full extract of Ernst’s valuable article, and ‘we have to refer our readers to the paper itself. Celedon has recen published materials upon the Kéggaba language, which is distantly related to Guajiro (Paris: Maisonneuve & Co., 1886), and spoken in the Sierra Nevada of Santa Marta.—A. S. Gatschet. CONTRIBUTIONS TO ANTHROPOLOGY AND PREHISTORICS OF Bavarta.—The latest number of this celebrated periodical,’ which is published by the Munich Society of Anthropology, does not lag behind its predecessors in elaborateness and scientific importance. The curious subterranean gangways and corridors, which occur 1n 4 large portion of Wiirtemberg, Bavaria and Austria, were first explored and described between 1830 and 1840, Among the rustics many fairy and hobgoblin tales circulate on their account, these spirits being called Erdleutl, Erdweibl, Schratzeln, Ratzln, Wichtelen, Alraune, Weiberl, and many other names, and represented as industrious and very bashful little beings. Some of these corri- dors take their starting-point from old castles, churches, mansions and their cellars, even from buildings now used as breweries, an parson’s dwellings. Dr. Aug. Hartmann’ has published his results on this part of archeology in the exhaustive article “ Unterrdische Gänge,” pp. 93-129, stating that many other investigators are DOW engaged on this subject, and expect to publish their results in due time.

Julius Naue continues his instructive enumeration of collective tombs or ancient cemeteries discovered between the Ammer and the Staffelsee, Bavaria. They all belong to the bronze and iron periods, and many of them are Roman. Some walls found near Uffing are of the cyclopean type and built of undressed stones. About thirty stone-graves are represented in the illustra- tions, many of them showing the body in situ. A physician of Tölz, Dr. M. Höfler, has composed a statistic memoir on “ Cretinis- tic Changes observed with the Living Population of the District of Tölz,” pp. 207-257. All cretinistie dispositions and alterations are deduced by the author from climatic causes. Among the char- acteristics of cretinism various authors are enumerating the pug- nose, prognathism, great distance from one eye to the other, bad condition of the teeth, small stature, lateness of the puberty period, weakness of the vocal and auditory organs, imbecility, goitre, struma and scrofula. The geological formations which show the largest number of strumous individuals residing upon theth are all of marine origin, as marine sandstone, eocene, keuper with marine shells. A map of the district, which lies upon the Isar River, is added to show the dissemination of the population affected with strumous diseases and complications.—A. S. Gatschet. FoLk-LorE—How THE LIZARDS WERE ONCE LitrLe MEN. Mr. L. L. Frost, of Susanville, Lassen Co., California, tells us how, when he requested an Indian to gather and bring in all the arrow- points he could find, the Indian declared them to be “no good,” that they had been made by the lizards. Whereupon Mr. Frost drew from him the following lizard story : There was a time when the lizards were little men, and the arrow-points which are now found were shot by them at the grizzly bears. The bears could talk then and would eat the little men whenever they could catch them. The arrows of the li men were so small that they would not kill the bears when shot into them, and only served to enrage them. At last there was a smart little fellow who lived with his grandmother. One day he was making a bow and his grandmother asked him what he was going to do with it. He replied that he was going to kill a bear. His grandmother told him the bear had killed all his family, and so she refused her consent for him to go hunting, and kept him Prisoner in the campooda. But the boy knew of a valley near by to which the bears came every evening to feed. He had finished 1s bow and gathered up his arrows, and when one day his mother went for water he stole away to this valley, and, climbi à tree, waited for events. Pretty soon a number of bears came into 1 . . dia aane he marie publica, Bogota, 1884, vol.

At this the big boss bear which had killed so many of the little-men, and of which all were id, came under the tree, and sitting himself on his haunches, looked up and asked the little fellow what he was doing up there. To which the little fellow replied, that he was going to kill him, the big boss bear. This reply tickled the bear so that he began to laugh, and making a great guffaw, opened his mouth so wide that the little fellow could see far down his throat, when quick as lightning he drew his bow and shot one of his arrows with one of these little points on it down the ope:. throat of the bear and into his vitals, whereupon his laugh turned into a roar as he fell down, rolled over, and died. All the rest of the bears took to their heels and scampered up the valley and over the mountains. The little fellow went home and related what he had done, but his grandmother refused to believe him. But the next day the whole settlement gathered to hear the story, and all hands going to the valley, found the dead bear. This made the little fellow a great hero. Ever since that time the bears have hid away in the brush, and are afraid of men. Thus they have lost their power of speech. P The Indian could not tell how the little men became transformed into lizards. SCIENTIFIC NEWS. —Professor Amos H. Worthen, State Geologist of Illinois, and Curator of the State Museum of Natural History, died on Sunday, May 6th, 1888, at his home in Warsaw, Illinois, of pneumonia, at the age of nearly seventy-five years. For over thirty years he been constantly engaged in the survey of, and in writing and pub- lishing the reports upon the geology of his adopted State. He was born at Bradford, Vermont, October 31st, 1813. He was the son of Thomas Worthen, his mother being an Adams of Revolutionary and Presidential stock, and he was the youngest, save one, of a large family of thirteen children. He received his education in the common schools of his native town, and at Bradford’s then famous academy. At an early age, before arriving at his majority, he married, January 14th, 1834, Miss Sarah Kimball, of Warren, New Hampshire, whose death occurred a little over a twelve-month ago. He emigrated to Kentucky in August, 1834, and his June, 1836, removed to Warsaw, Illinois, where he made permanent home, With his brothers-in-law, the Kimball boys, oF one of them, he became first a forwarding and commission m ae and later dealt in dry goods at Warsaw.

The party gathered at Paoli on the evening of the first, when papers were read by Mr. James E. Humphrey, of Indiana University, upon Asa Gray, and by Dr. John M. Coulter, of Wabash College, upon the Discovery of the Yellow- stone Park. From Paoli a wagon ride of thirty miles brought the party to the cave. On the return trip the newly-discovered Marengo Cave was visited, which all agreed was superior in a _except extent to Wyandotte ‘Cave.

A SHORT time ago, it will be remembered, an English gentle- man, eminent as a classical scholar, and as a man of refined and esthetic tastes, otherwise culture, delivered a lament in this city onthe decadence of literature and the usurpation of science. He Whom we are wont to call, without titular prenomen, Matthew Ar- nold, has long enjoyed the esteem of all English-speaking peoples, and I think that I can safely say that scientific men generally com- miserate with the eminent littérateur in his evident grief, although they must equally generally fail either to discover the ground for his prognostications or to dread the impending dilemma, The Cas- sandraic laments of the apostle of culture have long been re-echoing throughout Great and Greater Britain, and his latest utterances Were essentially the repetition of the wailings poured out into the Sympathetic ears of the select Cantabrigian scholars and published broadcast in the Nineteenth Century some eighteen months ago (Aug. 1883, pp. 216-230). What his feelings were then and long before are thus told by him. | “< No wisdom, nor counsel, nor understanding, against the Eternal! says the Wise Man? Against the natural and appointed course of things there is no contending. Ten years ago I remarked on the gloomy prospect for letters in this country, inasmuch as while the aristocratic class, according to a famous dictum of Lord Beaconsfield, Was totally indifferent to letters, the friends of physical science to “y other hand, a growing and popular body, were in active revol against them. To deprive letters of the too great place they had hitherto filled in men’s estimation, and to substitute other studies 482 Culture and Science. for them, was now the object, I observed, of a sort of crusade with the friends of physical science—a busy host important in itself, im- portant because of the gifted leaders who march at its head, import- ant from its strong and increasing hold upon public favor. “T could not help, I then went on to say, I could not help being moved with a desire to plead with the friends of physical science on behalf of letters, and in deprecation of the slight which they put upon them. But from giving effect to this desire I was at that time drawn off by more pressing matters. Ten years have passed, and the prospects of any pleader for letters have certainly not mended. If the friends of physical science were in the morning sunshine of popular favor even then, they stand now in its meridian radiance. Sir Josiah Mason founds a college at Birmingham to exclude “ mere literary instruction and education ;” and at its opening a brilliant and charming debater, Professor Huxley, is brought down to pro- nounce their funeral oration. Mr. Bright, in his zeal for the Uni- ted States, exhorts young people to drink deep of ‘ Hiawatha;’ and the Times, which takes {the gloomiest view possible of the future of letters, and thinks that a hundred years hence there will only be _a few eccentrics reading letters and almost every one will be study- ing the natural sciences—the Times, instead of counselling Mr. Bright’s young people rather to drink deep of Homer, is for giving them, above all, ‘the works of Darwin and Lyell and Bell and Huxley, and for nourishing them upon the voyage of the ‘ Chal- lenger? Stranger still, a brilliant man of letters in France, M. Renan, assigns the same date of a hundred years hence, as the date by which the historical and critical studies, in which his life has been passed and his reputation made, will have fallen into neglect, and deservedly so fallen. It is the regret of his life, M. Renan tells us, that he did not himself originally pursue the natural p7 ences, in which he might have forestalled Darwin in his discoveries. Are Mr. Arnold’s representations respecting the attitude towards literature on the part of the advocates of physical science literally correct? Are they not exaggerated? Most certainly the curricu- lum of Sir Josiah Mason’s Science School does not exclude literary instruction, but only such as the sole objective end, and Professor Huxley happily anticipated the objection made on the occasion Te- ferred to by Mr. Arnold. As I have elsewhere’ shown, m 4 review of Professor Huxley’s Science and Culture, he fully ro nizes the urgency of literary culture, and simply deprecates aP 1 The Critic (New York). : i Culture and Science. 483 undue attention to the neglect of more practical studies. On the occasion in question he merely reiterates them; and to those who would urge that want of cultivation of the ancient languages and literature entails narrowness of thought, he replies that “ the advo- cates of scientific education might fairly enough retort upon the modern Humanists that they may be learned specialists, but that they possess no such sound foundation for a criticism of life as de- serves the name of culture. And, indeed, if we were disposed to be eruel, we might urge that the Humanists have brought this reproach upon themselves, not because they are too full of the spirit of the ancient Greek, but because they lack it.” Nevertheless, he after- wards says, he is “the last person to question the importance of genuine literary education, or to suppose that intellectual cul- ure can be complete without it. An exclusively scientific training will bring about a mental twist as surely as an exclusively literary training.” He thinks that there is no need, however, that such a catastrophe should happen. Instruction in English, French and German, such as is provided for in the Mason Scientific School, renders accessible “the three greatest literatures of the modern world,” and if an Englishman cannot get his literary culture out of * his Bible, his Shakespeare, his Milton, neither will the profoundest study of Homer and Sophocles, Virgil and Horace, give it to him.” These opinions are valuable as emanating from one who in his own person combines scientific and literary culturé of no common order. But what is culture? From the writings of Mr. Arnold, as well. from the observations of those who are generally conceded to be men of culture,” I infer that it has, in the opinions of such, a narrower range than is admitted in the dictionaries of the English uage. Therein we learn that culture is “the application of labor or other means to improve good qualities or growth or, Specifically, any training or discipline by which man’s moral and Intellectual nature is elevated; or, “the result of such training, : enlightenment, civilization, refinement.” Further, we learn that ne word culture has made its way among us from Germany mainly through the influence of Goethe, and that “ we speak now 9 a9 culture, whether of a nation or individual, as a kind of col- ive noun for all that refers to the higher life.” But it appears that such definitions are too latitudinarian and vague, According to the special culture-worshippers, it seems that "be things must be done and certain other things left undone to ive to entry into the fold of culture. For example, above all 3 484 Culture and Science, things the Latin and Greek languages and literatures must be mas- tered, for the main object in life must be to make and understand classical allusions, and there can be no more grievous sin against culture or more glaring evidence of want thereof than not to under- stand every inuendo or allusion made in polite converse which springs from a classical source; not only ancient but modern poetry must be read, and not only read but enjoyed (this too is essential), and the principles of metric composition understood ; otherwise will the failing individual incur the charge of lack of culture. With a touch of pity Mr. Arnold recalls that “ Mr. Darwin once owned to a friend that for his part he did not experience the necessity for two things which most men find so necessary to them—poetry and religion; science and the domestic affections, he thought, were enough.” On the other hand, a very limited knowledge or even ignorance of things practical or natural is tolerable from one who has the positive qualifications specified. Even mathematics has entered too largely into the curriculum of the universities of England, and Mr. Arnold, for instance, declared on the occasion of his address here noticed, that “if in the Cambridge Senate House one may say such a thing without profaneness, I will hazard the opinion that for the majority of mankind a little of mathematics, also, goes a long way- Of course this is quite consistent with their being of immense im- portance as an instrument to something else; but it is the few who have the aptitude for thus using them,. not the bulk of mankind.” Many there are and many must there be who will object to the restriction of the term culture as thus advocated. In fact, the issue, so far as Mr. Arnold is concerned, is not between culture and sci- ence, but between a one-sided attention to classical studies and certain departments of science. The alternatives, as they appear to Mr. Arnold, are expressed in the following terms :— “A certain president of the Section for Mechanical Science in the British Association is, in Scripture phrase, ‘ very bold,’ and declares that if a man, in his education, ‘has substituted literature and history for natural science, he has chosen the less useful alter- native.’ Whether we go to these lengths or not, we must all admit that in natural science the habit gained of dealing with facts 15 a most valuable discipline, and that every one should have some experience of it. i “ But it is proposed to make the training in natural science the main part of education, for the great majority of mankind at i K . Culture and Science. ' T rate. And here, I confess, I part company with the friends of physical science, with whom up to this point I have been agreeing. In differing from them, however, I wish to proceed with the utmost caution and diffidence. The smallness of my acquaintance with the disciplines of natural science is ever before my mind, and I am fear- ful of doing them injustice. The ability of the partisans of natural science makes them formidable persons to contradict. The tone of tentative inquiry, which befits a being of dim faculties and bounded knowledge, is the tone I would wish to take and not to depart from. At present it seems to me, that those who are for giving to natural knowledge, as they call it, the chief place in the education of the majority of mankind, leave one important thing out of their account —the constitution of human nature.” That important element to the constitution of human nature, we elsewhere learn. A knowledge of all nature (and man is a part) is the domain of Science, but still, we are told, “it will be knowl- edge only which they give us; knowledge not put up for us into relation with our sense for conduct, our sense for beauty, and touched With emotion by being so put; not thus put for us, and therefore, to the majority of mankind, after a certain while unsatisfying, wearying,” ; I cannot forbear, in this connection, to once more cite Mr. Arnold. In his Cambridge address he recalled to his auditors a certain utterance of his of the past. s Some of you,” he said, “ may have met with a phrase of mine which has been the object of afgood deal of comment; an observa- tion to the effect that in our culture, the aim being to know our- selves and the world, we have, as the means to this end, to know the best which has been thought and said in the world.” But to know only the best, however desirable—and it is super- eminently so—is only to very imperfectly know the world and human nature. And the experience of many in this audience will attest to the fact that idiosyncracies are only partially controlled by poate. Many classical students,—many who have passed with yee a of our colleges after having pursued the entire curriculum yi e umanities—have shown a lack of morality and integrity all e more glaring because of their culture, and I doubt not that ee as you may recall those whose scholastic training has been ut yet who have ended their career in a prison cell. Some of _ ose who have thus lapsed have done so in consequence of the inapt- hess of their furniture for the struggle of life. There are those of 486 Culture and Science. them too, I know, who have charged their incomplete lives to that insufficiency of a collegiate course for the practical end of existence. This insufficiency has become so patent to many that they have demanded a change in the college curriculum, and this demand has come less from those interested in scientific pursuits than from those who have contemplated from outside the triumphs of science and have desired its advantages to be more feely extended and opened. The advantages of a scientific training are so evident that they need not be urged. In the words of Mr. Arnold, “ the great results of the scientific investigation of nature we are agreed upon knowing, but how much of our study are we bound to give to the processes by which those results are reached? The results have their visible bearing on human life. But all the processes, too, all the items of fact, by which those results are established, are inter- esting. All knowledge is interesting to a wise man, and the knowledge of nature is interesting to all men.” It is in view of this conceded usefulness of science and its relations to everyday life that there is an ever-increasing demand on the part of comparatively disinterested lookers-on to force it into college. This demand, as before indicated, is not so much fromthe acknowl- edged representatives of science as from the general community, and men of science interpose ever to moderate the demand and to recom- mend the retention of what are called the humanities in the educa- tional course. They urge that it is not the part of science or true culture (which amount to almost the same thing) to reject the one and to devote attention alone to the contemplation of gross matter. They are satisfied to give room and time, so far as may be possible, to all knowledge, and they do not find fault even with those who, like Mr. Arnold, think that “if there is to be separation and option between humane letters on the one hand and the natural sciences on the other, the great majority of mankind, all who have not exceptional and overpowering aptitudes for the study of nature, would do well to choose to be educated in humane letters rather than in the natural sciences. Letters will call out their being at more points, will make them live more. “ And, indeed,” continues Mr. Arnold, “ to say the truth, I cannot really think that humane letters arein danger of being thrust out from their leading-place in education, in spite of the array of authorities against them at this moment. So long as human nature is what it 15, their attractions will remain irresistible. They will be studied more Culture and Science. 487 rationally, but they will not lose their place. What will happen will rather be crowded into education other matters besides, far too many; there will be, perhaps, a period of unsettlement and con- fusion and false tendency ; but letters will not in the end lose their leading place. If they lose it for a time, they will get it back again. We shall be brought back to them by our wants and aspir- ations, And a poor humanist may possess his soul in patience, neither strive nor cry, admit the energy and brilliancy of the parti- sans of physical science, and their present favour with the public to be far greater than his own, and still have a happy faith that the nature of things works silently on behalf of the studies which he loves, and that, while we shall all have to acquaint ourselves with the great results reached by modern science, and to give ourselves as much training in its disciplines as we can conveniently carry, yet the majority of men will always require humane letters, and so much the more as they have the more and the greater results of science to relate to the need in man for conduct, and to the need in him for beauty.” There is much in these utterances of Mr. Arnold which can be re-echoed by the man of science. Doubtless the exclusive status of the humanities in the educational curriculum has been lost be- yond redemption; in some institutions, at least, they no longer take the lead, and above all, their study has been to some extent sanctified by scientific methods. But the enlightened chiefs of Science, far from denying, claim a place for the humanities parallel with those of their own chosen departments. What they do pro- pose, in response to popular clamor, is not to exclude classical Studies, but to leave to those students who have matured sufficiently to face a near future the option of a course which may be most useful to them in their after careers. The knowable is only less measurable than the unknowable, but human capacity and life are nite, Grecolatry and Latinolatry are sometimes obstructive. The physician will have less use for a profound knowledge of the humanities than of humanity ; the chemist or miner will doubtless find Greek and Latin of use, but much less than German or French — and still less than an elementary acquaintance with matter. The future merchant may be glad to bandy classical allusions with his customers, but a knowledge acquired, in the schools, of the objects ofhis trade will save much cost and labor in those years when time and labor are of most account. Let all be allowed to elect those 488 Culture and Science. studies which may be most useful to them in their chosen walks in life. In coming time there must needs be a modification of educational methods for adaptation to the increasing ramification and develop- ment of the tree of knowledge ; and if early youth is the best time for learning languages, so is it—and to even a greater degree—the best time for the cultivation of the logical and observing faculties. There must be sacrifice of some branch of learning, and what that shall be should probably be determined by the position of the indi- vidual and his tastes and aptitude. A technical education is at least more likely to be of future use to most persons than a classical one, and will certainly fit one better for the struggle of life, even if, as might be contended, it will be less apt to render him “ philosophi- cal ” under its calamities. I cannot forbear, even at the risk of being regarded digressive, to here interject some remarks respecting the place of the classical languages in general philosophy. We are constantly being told that the Latin and Greek are the most perfected and the highest developed of all tongues, and it is implied that others are less so to the extent by which they deviate from those stocks. I have no hesitation in utterly denying such a statement, and the claim in question is the result of that lack of broad culture which is inci- dent to exclusive or undue attention to what is called a classical curriculum. The Greek and Latin languages really represent an immature although nearly adolescent stage of linguistic develop- ment, the former being nearer the primitive stage, while the latter is on the whole appreciably more advanced in natural development. The inflections, which have been claimed as a feature of excellence, in truth are characteristic of the youth of language and of barbar- ous peoples. Such nations, for example, as the American aborigines (Choctaws, Creeks, ete.) and the Eskimo, exhibit a complexity of inflection which is immeasurably in advance of the classical ones, and the same reasons which have been urged for the supremacy of Greek and Latin are applicable in a far higher degree to the Eskimo and Choctaw. The decay of inflections may almost be said to be in an inverse ratio to the healthy growth of expression, and we may justly claim, on scientific grounds, that of all lan- guages, English is the most advanced in its developmental career, — so far at least as differentiation of its elements is concerned. These utterances, although they may appear heterodox to some, I feel Culture and Science. 489 assured will be challenged by no scientific philologist. It would be easy to justify them, but time forbids. I close, therefore, with some ideas as to the relations of Science and Culture. Science is often personified as an aggressive being and even as a demon, shoving and pushing all else away and.endeavoring to throttle and kill all else, that it alone may live and flourish. A falser conception is scarcely possible. This aggressive demon is not science, but a man of straw. Yet the disciples of theology and the apostles of culture seem to be made alike unhappy in their con- templation of the portentous and horrid offspring of their imagin- ings, and batter away at the impassive man of straw while com- plaining of his aggressions, Science is rather a goddess who is rich in attributes and ready to reward her worshippers, but coy in her gifts ; she is generous only to those who worship at her shrine in sincerity and truth, and who supplement their prayers by continual labor and deeds. To such she distributes her gifts much according to their deserts. Her worshippers are generally content with their several portions, and in her temple enjoy such sweet communion and peace of mind that they envy not the lots of those outside ; if at all solicitous for any outsiders they are actuated by motives of philanthropy and benevolence alone to invite such to share with them. . What other possible motive can there be for proselytism? They repose in the temple, itself on an eminence above the turbid billows of popular boisterousness, and can contemplate without alarm the strife of faction and of sects below. The outcries and assaults against science are, therefore, without justification, and are evidently the outcome of jealousy and rivalry among the worship- pers at other shrines; those interests appear to be imperilled, and they dread popularity so manifested by the number of votaries wending their way in ever-increasing throngs to her temple. Such pilgrims, however, are not unthinking followers of aggressive and proselytizing apostles, but are attracted by the clear atmos- phere of the heights on which the temple is perched and by the gifts- which the goddess half conceals and only imperfectly exhibits to new disciples. Near her portals, there are no runners who clamor to all in view to come in and believe as they do or be killed and damned, The priests who guard her shrine warn those that would approach to come not save they are prepared to cast off their garments of preju- dice and to test all things by trained sense, experience, and reason. 490 Culture and Science. Her votaries are not forbidden to doubt what is uttered in her tem- ple; doubt as encouraged as a prelude to faith. Science is most catholic in her regards, and none are denied entrance to her temple who submit to her laws. Conditions are imposed, it is true; but all those who give obedience to the few conditions are admissible. One of the conditions is that common sense intensified shall be applied to all questions. If it is the his- torian, he must learn to doubt and to weigh the statements handed down from posterity ; if the Greek or Latin scholar, he is refused, not because of his Greek and Latin as taught in the schools, but because only so knowing he knows too little and too imperfectly ; when he has gained increased knowledge and breadth of view so that he knows his language as a harmonious part of a great whole, he, too, is eligible. Science takes cognizance of all nature and all the outcome of nature. How, then, can there be any antagonism between science and culture when true culture is only an esteemed and devoted offspring of science? Any antagonism between the two is as causeless and insensate as the revolt of the members against the body imagined in the ancient apologue. Gross Anatomy of Campeloma. 491 ON THE GROSS ANATOMY OF CAMPELOMA. BY R. ELLSWORTH CALL. PTa collection of a large number of specimens of Campeloma subsolidum Anthony, in the Des Moines river, Iowa, in early August, presented opportunities to somewhat carefully study the coarser anatomy of the genus as exhibited in this species. The results of this study are herein given, It may be noted, as intro- ductory, that an unexpected closeness of structure to that of the foreign genus Paludina was developed, and, further, that the gen- eral diagnosis given by Dr. Stimpson! will need some slight emen- dation, particularly in respect to certain external characters, and in respect to the lingual teeth and the branchial lamine. External Characters.—In the living and recently dead animal the color of the foot-mass is light lead or bluish white. Viewed from above, the cervical lappets, foot, operculigerous lobe, tentacles and proboscis are further enlivened by irregularly scattered bright orange-yellow dots. These dots are, on the tentacles and proboscis, arranged in somewhat regular transverse rows, giving a barred appearance to each. These last-named organs are, moreover, marked by an abundant deposition of black pigment immediately under the cuticular membrane. The under surface of the foot, the crawl- Ing disk, shows, in living specimens, the large longitudinal pedal muscles. When these muscles contract, in the act of withdrawal into the shell, the anterior margin of the disk is reflected upwards and backwards over the proboscis and tentacles. This reflected portion is, as a whole, then bent backwards and downwards to be finally covered by the posterior portion of the foot, the upper sur- face of which carries the operculum. The whole mass is then with- ‘drawn into the shell. During the period of reproduction, when the organs devoted to that function are in a condition of marked activity and distension , the animal, especially of the female, cannot soy retracted. In this respect it resembles most of our large ices, Sexual Features.—The sexes are readily distinguished, in life, by — means of the right tentacle, which, in the male, is very much larger -than its fellow and rather more curved outwards (Plate VIL, Fig. 2% : : 1 Smithsonian Mise. Coll., No. 144, p. 35, 1865. 492 Gross Anatomy of Campeloma. and VII. of Fig. 1, in the text), Again, as appears below, the shells. differ in certain particulars of corresponding dimensions. The male seminal duct is displayed throughout nearly its whole length by clipping the mantle along the extreme left of the branch- ial chamber. The vas deferens superior (IV., Fig. 1) arises from a point on the anterior left third of the testis (II., Fig. 1). This latter organ is placed immediately under the right duodenal fold of the intestine (I., Fig. 1). It is about three times longer than wide, and whitish in color. The vas deferens supe- rior after passing anteriorly to a point near the anal extremity of the intestine is suddenly bent ~Y obliquely backwards and traverses the floor of the branchial chamber for a short distance, but soon turns forward again at a somewhat acute angle. At this point (III., Fig. 1) isthe prostate. The vas deferens inferior (V., Fig. 1) is rather long, narrow, and nearly straight, _ and is continued along the floor of the right tentacle to the verge (V I., Fig. 1). The right tentacle thus becomes an intromittent organ in the process of copulation. This tentacle is somewhat flattened above, presenting, in cross section, an elon- gated ellipse. It is somewhat less in length than its left fellow, and is rather more curved outwards. In the gravid female the gestatory sac (Plate VII., Fig. 5, ¢) oc- cupies the greater portion of the body whorl on the right side. It is- readily distinguished in the living specimen by the greater deposit of black pigmentary matter in its thin outer walls. Anteriorly the sac opens into a rather small duct, the mouth of which is prolonged into the branchial chamber about 2 to 2.5 millimetres (b, Plate VII., Fig. 5). This duct is guarded at each extremity by rather power- ful sphincter muscles. Anteriorly the walls of the gestatory sac are slightly thicker and are modified into longitudinal folds or ruge leading towards the duct. These possibly are of use mm guiding the extrusion of the young. During the summer and fall months, and often also in hiber- nating specimens, the gestatory sac is crowded to distension with young, in various stages of development (Plate VII., Fig. 5, c). Those most anterior are, in early August, nearly or quite through their prenatal growth, and are less closely crowded upon one another acoe ti] w Tig. 1. Gross Anatomy of Campeloma. 493 than are those in the rear portion of the sac. All the young in the anterior portion possess shells. The shell of the young at | | | | EILL Li | ELLELE BSBA AE ©! LLI AT AHIR ATA ae ae. PELEELEEEEE TITS I FIG. 2, this stage is devoid of colored epidermis, is crystalline white, and possesses from 2 to 2} complete whorls. The apex is very short and blunt, the first whorl being nearly uniform in diameter throughout its length, while the body whorl is very large, com- prising fully nine-tenths the entire bulk of the shell. The darker tentacles and the black eyes at their outer base are readily seen through the substance of the shell. The average dimensions of a dozen or more young examined were, for length 3.5 mm., for — diameter 2.96 mm, The embryonic whorls never, so far as exper- lence goes with mature specimens with completely preserved apices, acquire the characteristic green epidermal coloring. : 494 Gross Anatomy of Campeloma. The number of young is variable, the large mature specimens containing, as might be expected, the greater number of young shells. ‘Twenty specimens were carefully examined with a view to this feature, with the following result :— = Young. popan Young. | Sip | Young. bo Sings Young. | | 1 36 6 wn n 2 16 47 2 42 7 62 |] 12 | 17 42 8 51 8 2 Pe he 18 64 4 35 9 s or u 58 19 63 5 41 10 38 || 16 34 20 50 | pa These twenty individuals, therefore, present an average of forty- three young. Aside from the tentacular differences which exist between the male and female, both tentacles of the latter being uniformly sub- ulate, a further sexual difference appears in the greater size and somewhat more globose character of the female shell. Coördinated with this difference in dimensions is the more shouldered character of the whorls in the female specimen, a difference connected with the position and necessarily large size of the gestatory sac. The males are more regularly conical, with rather less oblique aperture, and are of considerably less globose appearance than are the females. This difference was supposed to be of value in determining the sex when only the shell was at hand. To test it as a sexual differen- tial character, thirty-six of the largest males and an equal number of the largest females were selected from a finding of more than a gallon of C. subsolidum, taken on August 6, 1887, and were care- fully measured. The results appear in the following :— TABLE OF DIMENSIONS. MALES. : } No. 1 | II No I. fi.

A comparison of ratios shows the numerical values of differ- ences, as follows: Length of male to its diameter, 23 $$$; length of female to its diameter, 34 37; length of female to length of male, 3133.; diameter of female to diameter of male, 18 434. The differences of lengths is 5.561 and of diameters 2.893. It would appear, then, that this degree of difference may be of diag- nostic value in the matter of sex. The diagram, Fig. 3, is designed. to present this sexual peculiarity in a graph- = ic form. The marginal numbers represent millimetres. The ordinates represent the lengths, and the ubscissas, which have the w -~ Same scale, represent diameters. The cir- cular conventional sign represents the male and the triangular character the female spec- imen. The average dimensions of each `~.. group are represented by the open conven- tional sign with its distinguishing sex mark conjoined. It will be seen that while the dots fall into two pretty well-defined groups, the range of greatest variation follows the ordinates, and that this range is comparatively greater for the female than for the male form. In other words, the males are more constant in lengths and vary less in diameter, while, for the female form, differences in length are measurably compensated by corresponding increase in diameter. In connection with this character it may not be altogether amiss. to call attention to certain so-called species which have been based — upon the males of C. subsolidum. They are Campeloma milesii Lea, wa > aaa ay } . - 771 Tig 3 496 Gross Anatomy of Campeloma. C. coarctatum Lea and C. exilis Anthony. The same unfortunate cause of synonomy has led, in the genus Unio, to the erection of more than a hundred spurious species, in certain cases the females serving as a basis for not less than five specific names. The form of a shell in so extremely variable a group is certainly a very mis- leading character. Digestive Organs.—The buccal cavity opens on the middle side of the rather short proboscis near its base. Near the cesophagus (III., Fig. 3) and upon the floor of the buccal mass lies the radula. This is a small, narrow, chitinous organ, beset with numerous trans- verse rows of teeth, arranged according to the formula 3.1.3 (Fig. 3, Plate VII., and Fig. 4). The dentition is therefore teenioglossate. On either side, near the posterior end of the buccal cavity, open the ducts of the salivary glands (II., Fig. 3). These are small racemose paired glands, dirty white in color, and lie close upon the cesophagus. Including their ducts, they are about 1.5 mm. in length, and nearly or quite .25 mm. in width. The csophagus is long, irregularly winding, placed upon the floor of the branchial cavity, and opens, into a somewhat capacious stomach (IV., Fig. 3), near the middle of the whorl next the body-whorl. The intestine is of nearly the same size as the cesophagus, and does not enlarge until the opening of the biliary duct is passed (V. and VII., Fig. 3). At this point it is coiled upon itself to the left, forming what may be called the right duodenal fold, immediately under which lies the testis, as stated above. Turning again to the right, it is there directed forward, becomes slightly enlarged, forming the rectal portion of the intestinal canal (WIII., Fig. 3), which opens into the branchial cavity near the margin of the mantle on the right side (IX., Fig. 3). The liver (VI., Fig. 3) is a very large gland- ular body, completely filling the first two and a half to three whorls of the shell, Its contents are discharged into the duodenal portion of the intestine near the position of the heart. In color it is orange- red, and is somewhat larger and darker in the male than in the female form. This organ, like all other portions of the animal which lie next the shell, is inversed by a thin membrane, contain- ing pigmentary matter, the membrane itself being a continuation of the mantle. Respiratory Apparatus.—The branchial cavity is large, extend- ing backwards throughout nearly the whole length of the body- whorl. It opens towards the right side, its left margin being just PLATE VII. Gross. Anatomy of Campeloma. 497 above the base of the left tentacle. The chamber is somewhat less in size in the gravid female than in the male, a fact the explanation of which probably lies in the distension of the gestatory sac and its consequent encroachment upon the branchial space. The cham- ber narrows rapidly posteriorly, and hecomes laterally constricted, From its upper and left side walls is pendant the ctenidium (Plate ? Fig. 5, Br). This organ consists of a single row, contain- ing a great number of thin elongately triangular plates, connected above with the branchial vein. The right edge and lower extrem- ity of each plate is free, and each is constantly bathed with water. The plates become smaller as the rear end of the chamber is reached ; they are yellowish white in color, and are furnished with abundant cilia. The blood, which is aerated in these plates, is white. The attention of students with proper appliances at command is directed to these molluscs in respect to their embryology, nervous system, minute anatomy of the reproductive organs, myology and circulatory system. Only the crudest observations on these points were possible under the conditions which were presented to me, and such facts as were ascertained are repressed in the hope that some other one will be able to complete the work here outlined.

I ke age has always been a great deal of interest manifested in the lay as well as in the scientific mind as to the wild cattle of Britain. The British Association appointed a committee to inquire into the condition of these herds, and at a late meeting this com- mittee’s report was presented by Canon Tristram. The herds at present existing were stated to be those at Chartley, Chillingham, Cadzow, Somerford, Blickling, and Vaynol. The last (near Car- narvon) does not seem to be mentioned by Storer or Harting. The committee thought it would be extremely interesting if the noble owners of the three ancient herds—Chartley, Chillingham, and Cadzow—would co-operate with some other owner of a large park, if haply such could be found, willing to undertake the fol- lowing experiment: All calves which would ordinarily be con- verted into veal or steers should, instead, be sent to build up a new herd, which, combining the blood of the only remaining ancient herds and with no artificial selection exercised, might be expected to revert more nearly to the aboriginal wild type than could be achieved in any other way. The care with which the European bison is preserved in Poland, under the especial protection of the Czar of Russia, has been noted. The interest of the Russian and British “quality ” from the earliest date in taking means to preserve these aboriginal animals is most praiseworthy and contrasts favorably with the apathy of Americans in regard to their aboriginal bison. Why should not the American Association take this matter in hand, and, ere too late (if not, indeed, too late already), secure from government a regional reservation ant sufficient enactment that would ensure the preservation of this interesting species ? Some of these wild British herds were horned; most wer polled. Some of them became domesticated ; most of them became extinct. Their antiquity cannot be limited; they were among " original cattle of the island—indeed, descendants of the Uri tha roamed into this corner of Europe before it became an island. But some do not care to trace the origin of British cattle ppr than the historical dates of the subjugation of the various parts 0% Wild Cattle of Great Britain. 499 the island by Roman, Norseman, Dane, and Norman. The student who has devoted himself unremittingly to this historical aspect of the question is the Rev. G. Gilbert, of Claxton, Norwich. The views of this gentleman, who has paid much attention to the history of the polls, are worthy of study, and it is here appropriate to refer to them. Ido so by quoting extracts from several communications I have been favored with from him : “ My own opinion,” he writes (and he begins by referring to the Aberdeen poll) “is that there was in Scotland, on the east coast, long before the short-horn strug- gled into notoriety, even in England, herds of polled cattle which owed their best qualities of hardiness and combined power of pro- ducing good beef and milk from the same animal to that very breed which gave these properties to the short-horn—i.e., to that big polled white which seems to me to have come to Great Britain above eight hundred years ago with the Baltic Rovers, and to have existed in considerable numbers, in places widely apart, down to the beginning of last century without there having been any recent connection. “The polled herds in England, Scotland and Ireland all held, before there was much intercourse between cattle-men, one common infusion, and that was the blood of the whites from the far north. ose white cattle seem to have parted with their color more readily than they parted with their thick muscle (i.e., lean flesh), tending to milk, hardiness, and polled heads. (Of course recently, since 1750, there have been large transmissions of English cattle to Scotland, and vice versd, and also of English and Scotch cattle to Ireland. I doubt if ever before this century either England or Scotland has ever borrowed sires from Treland, though England has borrowed for quite a century Scotch sires, and Scotland Eng- lish sires for the same period.) Gradually, at the end of the last century, distinct types of those county herds which all had some ingredients common and, each, some distinct element, got more or less fixed, until they reproduced themselves, as they do now, even m non-pedigree stock, with tolerable certainty. I fancy the last half of last century saw the formation of all British breeds now existing in distinct form. The short-horns and all the polls hold the largest infusion of the big white, the Midland and Hereford hold the most of the old South Europe longhorn, whilst the Devon, Kerry, and small N orth Highlander hold the most of the type — Known as Bos longifrons, all of which seem to have been the first domestic cattle in Great Britain and Ireland. 500 Wild Cattle of Great Britain. “ I think that very likely Bos urus was already in both islands as a wild beast. But Bos urus and the big white are not the same. The big white was domesticated from the first, and probably came, as you yourself suggest, from the polled breeds of India. I am trying to gather all the evidence I can get to show what the last thousand years may have done to make British breeds what they are, and thence to infer what the thousand years before that may have contributed. The long-horn, as I fancy, came over with the Romans, and the white polls with the Danes long subsequently. It was through the working of this Danish introduction that all the polled breeds took their rise. I fancy during the Wars of the Roses in England and up to the time of the union with Scotland breeding cattle was pursued without any aims beyond these :— “1. Certain districts tried to get big oxen for labor. “2. Other districts avowedly preferred the smaller cattle, as better able to live in the huts with their owners. “Through these influences, up in the mountains, the smaller or (Bos longifrons) North Highland type kept its ground. In the plains and near the towns the cattle became larger, partly from selection, partly because their veins were filled with many inter- mixtures. Bulls would come from the south as baggage animals in the track of returning armies and would be crossed’ with enlarge the native cows. So all through the richer lands on the south and east side of Scotland there was not any fixed type for a century or two as there was in the north and the west. But still it was these cattle of the plains (I believe) which originated the ‘ doddies,’ “ Wherever the Dane (white polled) extended itself it broke the colors—first conveyed the disposition to throw occasional polled calves, The disposition to produce polled calves and the mixing colors are evidences of latent (perhaps very remote) connection with the Danish introduction. ; “Tt would be absurd to suppose that the Danish introductions were all that we now regard as ‘pure bred’—i.e., all alike and entirely of one descent. Probably there were a few cherished white herds in the north of Europe kept to one type; but, more likely, the cattle were early mixed through the predatory habits of the red-rovers. The Danes may have brought over here a few pute whites, gifts to their chiefs ; but they brought over far more W were carried off by their vessels from shores on which they touched Wild Cattle of Great Britain. 501 after leaving home but before they reached Britain; so that the Danish additions to Scotch and English breeds were not one but many. Still, it was among their introductions that their tendency to polled calves was brought to this island, and it came from the far north, where, even in the days of Herodotus, its existence was noticed. Before Herodotus we only find traces of it in rock sculp- ture in the far Orient. Thousands of years ago the polled form was developed (as I think) in India, and it worked its way thence to the shores of the Baltic overland through centuries of slow advances. From the Baltic it found its way to England and Scot- land. I do not think from England to Scotland, or vice versd, but that the same set of sea-rovers introduced cattle with polled tenden- cies into both countries almost simultaneously.” It should be stated that the above was written before the publi- cation of Victor Hehn’s work (already noticed), in which the latter traces the polled cattle of Western Europe to Scandinavia and the White Sea. Mr. Gilbert takes the history of these continental polls a step farther, following them, it will be seen, to the eastern coasts of Great Britain, landing them with the Baltic invaders, to become the determining element in forming the polled races now existing in Great Britain, whether north or south of the Tweed. “These,” writes Mr. Gilbert, “probably were our latest introductions.” Hence the polled breeds on the eastern coast would have had prior origin. The various British and foreign forms Mr. Gilbert thus indicates must be studied as a whole in connection with the appear- ance in Europe of the various hordes who reached it by two routes: First, by the northern route, descending upon Mid-Europe from the shores of the Baltic. Second, by the southern route, making their way upward, men and cattle, along the shores of the Mediterranean. The question has raged to which species these wild cattle be- longed? Professor Low says of these animals: “The wild breed, or, as it may be termed when domesticated, the white Forest breed —identical with the ancient Urus—is still preserved in a few parks, where the animals, herding and breeding only with one another, retain their pristine characters. Numbers, however, existed in the domesticated state in Wales until late in the last centarys: «<< .s Scattered individuals are yet to be met with,-as in the County of Sawa in no respect distinguishable from the wild cattle of the parks, | 502 Wild Cattle of Great Britain. J. E. Harting, F.LS., F.Z.S., the latest scientific authority who has given attention—and that in a most thorough manner— to the wild white cattle, says, in his British Animals Extinct, page 214: “The weight of scientific opinion, however, seems to favor the view that these wild cattle were descended from the Urus, either by direct descent through wild animals from the bull, or, less directly, through domesticated cattle deriving their blood principally from him.” Riitimeyer, Nillsson, Lyell, Darwin, and Boyd-Dawkins believe that our wild white cattle are descended from the Urus in one or other of the two ways above indicated; while Owen and Dr. J. A. Smith (“ Notes on the Ancient Cattle of Scotland,” in Proc. Soc. Antiq. Scotl., Vol. IX., p. 587) hold a-different view, and consider that Bos primigenius became extinct throughout the whole island in prehistoric times. “This may have been the case,” says Hart- ing, “in southern parts of Britain.” But he indicates conclusively that this could not have been the case in undisturbed Caledonia. In Ireland “ no trace of these wild cattle has been discovered, although remains of the smaller Bos longifrons have been procured from some localities.” The late J. Gibson, of the Museum of Science and Art, Edin- burgh, Scotland, writing on “Cattle” in the Encyclopædia Britannica (ninth edition), says : “ Bos taurus, var. Scoticus, makes the nearest approach of living forms to Urus, represented by Cad- zow, Chillingham, Lyme, and Chartley herds.” These herds have been preserved since early historic times. The pictures by famous artists—such as Ward, Landseer, and others— represent them faithfully. BRITISH WHITE POLLED CATTLE. Rev. John Storer’s work! is the most exhaustive we have on the subject of the wild white cattle of. Britain, while J. E. Harting, F.LS., F.Z.S., editor of the Zoologist, has published a more concise account.” The following is a tabular view of the various herds :— 1 Wild White Cattle of Great Britain. 2 Extinct British Animals.

ENGLISH HERDS. _ I Tue Somerrorp Park Herp, near Congleton, Cheshire, 1s a domesticated herd, but its cattle are very characteristic, having all the peculiar features of the White Forest breed. It is certainly of great, though unknown, antiquity, their owner, Sir Charles Shakerly, saying: “ We have no history of how they came or how long they have been here. I am of the third generation which has ! Extinct. 2? Domesticated. 504 Wild Cattle of Great Britain. known nothing about them. The tradition is that they have been here two hundred years.” It is probably the best representative extant of the hornless and tame variety of the originally wild white breed. It is of great importance, as showing what and of great value the numer- ous ancient herds of white polled cattle were. Perfect and in working order, it gives an excellent idea of what the Gis- burne (now extinct) and the Hamilton (now horned) cattle Š were originally. This her Frc. 1.—Head of White Bull, with black seems to be a connecting link ears and muzzle, of Gunton Herd. (From s : Storer’s Wild White Cattle of Great Britain.) between the domesticated white cattle and the wild, and also between those which had horns and those which were polled. An experienced eye cannot fail to trace a very close resemblance between them and the wild horned breed at Chartley. The park is well timbered, the quality of the soil and grass very good, though in the heart of the ancient forest region- The milking properties of the cows are good naturally, and have thus been fully developed. The white color of the cattle is accom- panied by black points, and sometimes spots on the neck and body. They are handsome and very uniform as to color. They may have been derived from some ancient monastery, one of which, Vale Royal, only twelve miles distant, has a somewhat similar breed. Storer gives a very full account of them as they existed at the time of his visit to the herd in 1875. II. Wo.triatox HALL Herp,! the property of Lords Middle- ton, situated three miles west from Nottingham, has become extinct during the last fifty years. It was generally known as “ the Old . Park Breed,” which indicated them to be an original and very ancient race. They were polled and had black points. The origi nally wild nature of the herd interfered with its thorough domestie cation, in-breeding hastening its extinction, as in many other park herds. They were of specially large and symmetrical proportions. Their pasturage, of considerable extent, was fairly good, though not particularly rich. They are supposed to have become enclosed from the grand old forest of Sherwood. The Wollaton (Somerford), Wild Cattle of Great Britain. 505 Chartley, and Lyme (these last two horned) formed the southernmost group of the ancient white cattle, and all were in tolerably close proximity. III. THE GissurnE Park Herp,! the property of Lords Ribblesdale, situated in the Valley of the Ribble, in the district of Craven, West Riding of Yorkshire. This herd became extinct in 1859, the cause being in-breeding. They were described by Be- wick in 1790 as perfectly white, except the insides of the ears, which were brown. They were thick and deep and as large as any short-horns, had mellow hides, and were excellent milkers. They are said to have been brought originally from Whalley Abbey, being enclosed from the “indigenous wild cattle which occupied the great forests of Lancashire. Professor Boyd-Dawkins preserves in the Museum at Owen’s College, Manchester, under his charge, the skull of “the last bull” of this herd. In a letter to me, referring to this, he says: “ The Gisburne cattle come nearer to the Chilling- ham cattle than any other breed, being white in color, with reddish- brown inside their ears. The only stuffed specimen and skull of this breed, now extinct, are in the Museum under my charge at Owen’s College, Manchester. The Gisburne breed represents, like the Chillingham, the domestic cattle of the Urus type which have never been confined in fields, and which, therefore, by contrast with the more domesticated animals, are frequently termed wild. The stuffed specimen above referred to is a cow, low in stature, with a prominent protuberance on the forehead, like that found in the Galloways. The skull, also hornless, and belonging to a bull, labelled ‘ The last of the ancient breed of wild polled cattle kept at Gisburne Park, Yorkshire, killed 11th November, 1859, and pre+ sented by the Rt. Hon. Lord Ribblesdale,’ proves that the male was hornless.” IV. Mippreron HALL Herp,! the property of the Asshetons, Baronets of Middleton, near Manchester, Lancashire, was quite an original one, of very ancient origin. They descended from the _ wild bulls that invested Blakele, close to Middleton Hall. They ; gave origin to the Gunton herd, in Norfolk. Dr. Leigh mentions them in 1700 (Natural History of Lancashire, Cheshire, and the Peak of Derbyshire, Book II., p. 8), but the origin he traces for them—from the Highlands of Scotland—must be regarde mere surmise, ; MOET _ V. Guytoy Park Hrrp,! the property of Lords Suffield, Situated in the northeast portion of Norfolk. The Gunton cattle 506 Wild Cattle of Great Britain. _ were brought from the Middleton herd and were a continuation of it. The cattle became thoroughly domesticated. They had black, or, at any rate, dark brown, points. They were deep milkers. They gradually disappeared; but in their day they had great influence on the cattle of the district. The Rev. George Gilbert confirms this, and also as to their size. They “stood up like dray- horses,” while they could be made enormously fat. VI. Burickytrye HALL Herp (Norfolk) is a domesticated herd still existing. It was derived from Gunton. The cattle had black points. They were considerably affected by the rinderpest, previous to which they were very useful in the dairy. Rev. George Gilbert, who gives a full account of them in Storer’s work, says the cows are not above the average of the Galloway and are below that of the Aberdeen. The following is the latest I have seen in refer- ence to this herd, and shows that it contains good material: “A remarkable novelty at this Norfolk show was an exhibition of sev- eral animals from Lady Lothian’s unique herd of white polled cattle, the beasts having black ears and points. A bull took a first prize, beating several fine Herefords. This curious herd has been kept at Blickling since the reign of Charles II., and it represents. one of the oldest types of cattle in the world.” (London Truth, July 7, 1887.) VII. Wooppastwick Herp, the property of Mr. A. Cator, Norfolk, a domesticated, still existing herd, derived from Gunton. The cattle had red points. They were large, would fat to great weight, and had large manes. They were kept pure up to 1840, when different crosses were had resort to. It is of importance to note that Mr. G. Gilbert states: “It is impossible not to notice that the white polled cattle, both at Blickling and Woodbastwick,. are quite distinct (in appearance) from the Norfolk and Suffolk. They are as distinct from the local polled variety as possible,’— and he also ineludes the Galloway and Aberdeen. Tue Brooke House, or Kerrison Herp! (Norfolk), were a domesticated herd before they became extinct. They were _ derived from Gunton, and had black points. Rev. George Gilbert, by relationship with the owner of this herd (Sir Roger Kerrison), is very well acquainted with it. He states they stood very high, and that there are traditions of a similar breed of white polled cattle in the Downham district occasionally, even now, polled eee of gigantic size being occasionally found. He saw one in 1877 wht m2 Wild Cattle of Great Britain. 507 certainly stood six feet high. These cattle may have also been derived from the stock of one of the monasteries of the Premonstra- tensian Order, which had privileges over certain manors, including Brooke and Kustead, in both of which parishes Sir Roger Kerri- son’s ancestors lived. Mr. Storer, speaking of this herd, concludes his account thus: “It demonstrates by the clearest evidence how strong has been the influence of the wild forest breed upon our domestic cattle, how wonderfully persistent is the type, and how it reproduces itself under the most unlikely circumstances—often, perhaps, when its very existence is altogether unsuspected.” IX. BURTON CONSTABLE Herp.'—This herd is situated in the Holderness or East Riding District of Yorkshire. Storer is not very definite about this herd as to its character. It appears to have been a polled herd. Bewick (1790) gives a brief account of it. He states it was carried off “a few years ago by a distemper.” These cattle were much larger than the Chillingham horned cattle, many weighing sixty stones (eight hundred and forty pounds). SCOTTISH HERDS. X. Arprossan Herp! (Ayrshire), property of the Lords Eglinton, was mentioned by Sir John Sinclair in 1814 as one of the then few remaining examples of Caledonia’s ancient breed. It survived till about 1820. They had black points. They were enclosed about 1750. They were traditionally believed to have been horned when introduced to Ardrossan. They were certainly all, or very nearly all, polled within the memory of man. The cause of their becoming hornless was the result of an introduction from the polled Hamilton herd. In other respects they seemed to have differed little from the Caledonian wild cattle, except that per- haps they were smaller. Mr. George Rob- AR ertson, author of several such works, in his Description of Cuningham and Ayr- shire, published 1820, says: “They are altogether wild ; they have no horns; they are distinguished by the name Caledo- ` nian,” being an offshoot of the older Ham- ilton. XI. Tae Hamrox Herp (Lanark- shire), known also by the names Cadzow pee mr ee and Chatelherault. Mr. Brown, chamber- Waras’ Zoology.) lain to the Duke of Hamilton, in Jesse’s Natural History, describes 508 Wild Cattle of Great Britain. the Hamilton Urus as having a body dun white, with black points, and the cows as seldom having horns. Sir John Orde says that they were anciently “all polled.” Youatt speaks of them as being polled, beginning his account of The Polled Cattle with a description of them.. Mr, MacGillivray, in his Essay on the Present State of the Outer Hebrides, says: “ A whitish dun color is also pretty fre- quently seen, not unlike that of the original wild cattle of Scot- Jand, both the horned breeds at Chillingham, and the polled one at Hamilton, and it is remarked that in all their traditions or fables of what are called fairy cattle this is the color ascribed to these animals.” At the sale of the late Dr. Knox’s collections a polled skull of the Hamilton wild ox was purchased by the late Professor Goodsir. It was labelled by him Urus scoticus, and added to the Anatomical Museum of the University of Edinburgh. Some oxen from this herd were exhibited not many years ago at one of the shows of the Highland Society, and were similarly described. In Milne-Edward’s Zoology, 1863, Figure 256, the “Head of young Scotch bull, Urus scoticus, or wild ox of Caledon, Cadzow,” is polled. (See Figure 2.) The skull is labelled “ White Ox of Scotland.” From this testimony it is pretty clear that the Hamil- ton herd was originally polled. So late as 1852, W. C. L. Martin, in his book on Cattle, says the Hamilton’s “are larger and more robust than the Chillingham. . . . The cows, and also the bulls, are generally polled or hornless.” And in 1862 Charles Steven- son wrote: “In the herd of wild cattle in Hamilton Park polled bull and heifer calves frequently appear. Latterly no bulls are kept which have not the short white horn tipped with black ; but there are a few cows and heifers polled. It may be mentioned that this breed was originally both polled and horned and that both types reappear, notwithstanding the care taken to breed them of a uniform type as to horns and color.” Thus is shown the gradual change from polled to horned. The reason given of their having become horned is stated by Sir John Orde, Kilmory, Argyllshire, "a have been from a Highland bull having accidentally got within the park. Some horned calves were produced, and by subsequent selection the herd had got horns generally, the horned character being preferred—likely from the fondness for the grandly-horned Highland cattle, which make such a picturesque feature of the Highland glens and straths. But their horns are “short,” a “long.” These celebrated polled cattle, variously known as the — California Gray Whale. 509 Cadzow, Hamilton, or Chatelherault—the first name being the name of their forest home, the second being one of the Scotch titles of the ducal owners, the third being their French title—are thus generally regarded as being the remains of the ancient breed of white cattle which was found on the island when the Romans first visited it, and which they represent as then running wild in the woods. The universal tradition in Clydesdale, where they were called “ Caledonian,” is that they have been at Cadzow from the remotest antiquity, and the probability is that they formed part of the establishments of the early British and Scottish kings. Sir Walter Scott’s stirring ballad on the hunting of the wild bull is too well known to need repetition. THE CALIFORNIA GRAY WHALE. (Rhacheanectes glaucus Cope.) BY JOHN DEAN CATON. FIRST saw this interesting animal eighteen years ago, when running down the coast on the steamer Orizava. We then met them in considerable numbers when on their migration north. We were running but a few miles from shore, and generally ob- served them on the seaward side, but sometimes on the shore side, Sometimes they appeared quite close to the ship and did not seem to be much alarmed by the presence of the steamer. I have since taken pains to inform myself of the habits and mode of capture of this great sea mammal and think I may safely say that it is the most interesting of all the species of whale known to inhabit the great seas, perhaps because it is the best understood. It does not inhabit the distant depths of the broad oceans but its habitat is confined to the coast line of the Pacific from Cape St. — Lucas at the southern extremity of the peninsula of California to Behring sea and even into the Arctic ocean, where it sports among the icebergs of the north with as much apparent pleasure as it rolls and tumbles among the great breakers in its southern range. | If other species of whales are as strictly migratory as this we lack the evidence to prove it. If others wander about into different: Seas, and even go from ocean to ocean, they do not move with that. 510 California. Gray Whale. regularity and system which constitutes what we call migration. With these this habit is as regular as the recurrence of the season, and is no doubt as universal as is that of most aquatic birds. Wintering in the south, this migration to the north commences in the spring, first with the males, who having no domestic duties or cares to detain them, leisurely proceed northward, and they are soon followed by the females with their young so soon as the latter are large enough to undertake the long journey. Not that either sex move in a body and together, for they are scattered along the coast for even months, though they generally move in schools of greater or less numbers, among which both males and females may occur. Undoubtedly the former were laggards, while the latter were of the advance of the females. Of all the families of whales, of this alone has it been possible to study the breeding habits with satisfactory results. Along the coast, in the southern part of their range, numerous lagoons are found indenting the shores, near the mouths or outlets of which, bars occur on which the surf breaks with great violence when the sea is rough, while the waters within are placid. These lagoons are the favorite breeding grounds of these whales, where they congregate in great numbers to bring forth their young, which occurs during the winter months, say from November till March. Although the fiercest fighters of all known whales it has not been known that they are quarrelsome among themselves. So far as known, peace and quiet prevails among all the members crowded together in the upper ends of these water enclosures or lying-in hospitals. But few males have been observed to intrude themselves into the privacy of these retreats. The period of gestation is said to be about twelve months, and from analogy impregnation takes place within a very few days after the young are brought forth. Eliott’s exhaustive observations show that such is the case with the fur seals, whose period of gestation is the same. Indeed, this mast be so, when the period of gestation nearly corresponds with the year, else there could be no regularity in the time when the young arè brought forth, but it would occur irregularly at all seasons of the year. Another peculiarity of this whale is its fondness for sport or play : While this habit is solitary it is distinctly manifest. Its favorite amusement is to sport in the breakers or the bars at the entrance to bays, lagoons and rivers, and the greater the breakers, the more do California Gray Whale. SIL. they seem to enjoy them, for there they play and gambol about, in- creasing the foam by the use of their powerful flukes, sometimes fairly turning somersaults, while at others they will cease apparent exertion, allowing themselves to be rolled and tossed about, the passive sport of the angry waters. Of all the known species of whales, this is the most cunning, courageous and vicious. So terrible is it, that with the old imple- ments of harpoon and lance, but few whalemen would court an en- counter with it, and it early received the name of the Devil Fish. I have no account that it ever maliciously attacked an unoffending object, yet when it found itself pursued where escape was difficult, even before it was struck, it has been known to turn upon pursuers and dash a boat to fragments with a single blow of its powerful flukes, and so has many a life been lost. It was in the whale nurseries, in the retired lagoons, where the young were brought forth and nursed, for a considerable time after they were able to accompany their mothers for long distances out to sea, that the most terrible encounters occurred. The mother has a remarkable affection for her young, and will do and dare everything in its defence, hence the whalemen were cautioned not to strike the calf while the mother was living. If she would not resent a severe wound to herself, while there was yet hope for escape that she might live to nurse and take care of her offspring, when once her darling was injured her rage knew no bounds, and there was no escape from her but to run the boat into shallow water or upon the beach, It 18 said that when in port the masters of whalers, in convivial mood, each recounting his adventures and escapes, those among them who had ever pursued this whale, could silence all others when recount- ing the terrors of the chase, and would seek to rival each other in tales illustrating the ferocity and courage of the female when her young were in danger, and if the last in turn to come did not win the palm it was his own fault or rather his lack of inventive genius. This is the way the last one to relate his experience won the drinks. He said he was once pursuing an old cow whale, with a well-grown calf, and while he had cautioned the man in the bow not to touch the calf, the youngster presented so fair a mark that he could not ‘hold himself and so let him have it. Knowing what would follow, he instantly ordered all hands to pull for the shore, which fortu- nately was not far off. As they saw the enraged dam bearing down upon them like a tornado when they reached the shore, they tum- 512 California Gray Whale. bled out of the boat and thought they were safe. But no, she pur- sued them on land as well, and never stopped till she had treed them all! The danger of the pursuit was much lessened, and the chances of capture of these dangerous animals was much increased by the introduction of the harpoon-gun and the bomb-lance. By them the attack could be made at a safer distance, and the exploded bomb produced instant death. The inshore habits of these whales made it possible for the na- tives to attack and capture them even with their rude implements but as I have met no account of this south of Washington Terri- tory, and rarely except in the vicinity of the Strait of Fuca, it is not improbable that much of the belligerent disposition of the brute may have left him by the time hé has pursued his migratory jour- ney so far, and especially may the temper of the female have been improved when the defence of her offspring was no longer de- manded. Their mode of capture was simple though ingenious, but could have only met with disaster in their southern breeding grounds, Their mode was to attack with a large number of canoes, each armed with several men and provided with a number of inflated bladders, or air-tight sacks made of skins; to each of these was at- tached a light strong cord, at the other end of which was an arrow When a whale was sighted, the swiftly-paddled fleet pursued and embraced every opportunity for hours to shoot their arrows into him, always throwing overboard the proper air sack. Soon these began to tell by impeding his course through the water and preventing him from diving to as great a depth as formerly and obstructing — his progress when fleeing from his pursuers. Thus in a longer oF shorter time he might be literally covered with arrows, and so ob- structed and loaded down, so to speak, with the air sacks, that he became quite helpless and finally succumbed to his swarming ene- mies, when by their united efforts he was towed to the shore and utilized in their way. This was only rendered possible by the pe culiar inshore habits of this species of the whale. : For many years this whale was hunted from large whaling ships, which were anchored at convenient places near those locations where observation had shown the animal was most likely to be found, and from the ships whale boats were sent out to hunt for the game, and when captured they were towed to the ship and apa in the ordinary way. But this was an expensive mode of maintain- California Gray Whale. 513 ing a whaling station, and as the objects of pursuit became scarce— notwithstanding the improved mode of capture by the use of the harpoon-gun and bomb-lance—the pursuit became unprofitable, when Yankee ingenuity proved equal to the emergency and shore whaling stations were thought of. These are built upon the shore in sheltered places, but commanding an extensive seaward view. Convenient structures are erected and equipped with all necessary implements and apparatus, with boats and arms for the capture of the whale, and everything on shore for treating the captive when brought to the shore. Near the station was a high lookout upon which a watchman was stationed with a well-understood system of signals, by means of which he could telegraph the boats when far out to sea. Here the men built comfortable cabins where they lived with their families, and later, as the whales became scarcer, they could pursue other avocations when their time could not be em- ployed in the pursuit of their prey, which intervals increased as the whales became less and less abundant, till now many of these shore stations have been entirely abandoned. Here, in Monterey, the first whaling station was established on shore in 1851, and later another _ was established, both of which did a successful business for years, but. : within the last few years they have been entirely abandoned. Some of the buildings still remain but they are fast going to decay, and the old whale boats may now be seen leaning up against the sheds useless and abandoned. So at Carmal mission, a few miles across the peninsula; the absence of the game has compelled its desertion, and this is now true of most of the many whaling stations along this coast which once flourished. The station near the mouth of the bay of San Diego, I believe, is still kept up; at least when I passed it three years ago I saw two whales were on the ways. Altogether we may well fear that this interesting species of this _ Sreat family may before many years become extinct, as did the sea ee (unless governmental powers shall interpose to save them), Which existed in incredible numbers about Bering Island when the TFS navigator was cast upon it, and where he found his grave in The California whale may make a bolder and harder struggle for existence than did the Rhytina, but it is rapidly going to utter ex- tmction. While other species of the whale family have greatly diminished in numbers in all waters, still their habits protect them from final destruction, They have a wider range and cannot be it Ge California Gray Whale. slaughtered on any exclusive breeding grounds. Here their nurs- eries are limited to particularly favored places which are known and accessible to all who choose to murder them, and it is a little re- markable that the State of California has not, long since, by strin- gent laws protected them, at least in the nurseries within her bor- ders. If their capture were confined to the open waters of the ocean and to a reasonable distance from the mouth of the lagoons in which they breed, we might well hope to see them multiply rather than fade away to final extinction. Certain interests encour- aged the extinction of the vast herds of buffalo which once roamed over the plains and even the forests of our country, that the ranch- men might have better pasturage for their stock, but no interest can be promoted by the destruction of this whale while great interests would be subserved by its protection and increase. Other animals are protected which are of no practical value except as mere spec- tacles, while their existence involves a positive loss by the destruc- tion of vast numbers of food fishes. I might have stated before, that the California whale, though not the largest of the family, is of a good size, the largest measuring forty to fifty feet in length, though the average is considerably less than this. They are fairly robust in form and well covered with fat. They furnish no whalebone, but they produce from twenty to seventy barrels of oil, which, though not of the best quality, com- mands a good price in the market. Solitary individuals of several other species of whales are fre- quently taken at the shore stations along this coast. Editors’ Table. 515 EDITORS’ TABLE. EDITORS: E. D. COPE AND J. 8. KINGSLEY. The bill lately introduced in the Senate by Senator Beck to pro- vide for a National Zoological Park at Washington, “ for the ad- vancement of science and the instruction and recreation of the people,” is certainly a step in the right direction, and one which might well have been taken long ago. As might be expected, the plan receives the unqualified endorsement and support of the Smithsonian Institution and National Museum, as indeed it must that of all scientists, friends of science, and the general public throughout the country. The bill provides for an institution which shall be founded on a grand and liberal scale, and fully in keeping with the wealth, dig- nity and intelligence of the nation. The site is to be selected on Rock creek, just beyond the city limits, which would make the entrance to the grounds only a trifle over two miles from the Execu- tive Mansion. The proposed site is one of great beauty, and even grandeur, for at two points high walls of rocks rise out of the picturesque valley to a height of over eighty feet. _ The creek itself is a beautiful stream of very respectable propor- tions, describing a perfect letter S through the site to be chosen, and aside from its picturesque features it would afford unrivalled facilities for the care of aquatic mammals and birds of all kinds. Nearly the whole tract is covered by a fine growth of forest trees which, unless afforded immediate protection, is liable to be. Swept away by reckless real estate vandals. It is proposed that the Zoological Park shall be established by three commissioners, the Secretary of the Smithsonian Institution, the Secretary of the Interior and the President of the District of Commissioners, and when fairly established it shall be turned over to the perpetual custody and care of the ‘regents of Smithsonian. With the unrivalled facilities already enjoyed by the Institution through its multitude of correspondents and col- lectors, it would be possible to secure an immense number of val- uable accessions by gift, and it is estimated that fully one-half of all the collections could be so obtained merely by paying the cost of transportation. 516 Recent Literature. It is unnecessary to advance them any reasons why this bill should be passed, and the park established as proposed. We only. allude to the great advantages to science and the general public which would inevitably result from the gathering together at the capital of the nation of a great collection of quadrupeds, birds, and reptiles living and breeding under highly favorable con- ditions. The time is fast approaching when many of our most noteworthy American quadrupeds will exist only in parks and menageries. The buffalo is now almost extinct in his wild state, and the Rocky Mountain goat is also certain to disappear in a very few years more. Ours is almost the only great nation which does not maintain a national zoological garden on a grand scale, and we are glad to see that the idea of such an institution for us is at last taking tangible shape. It is eminently proper that it should be located at the capital city, which is now the scientific centre of the nation, and the Mecca which is visited annually by tens of thousands of citizens from every nook and corner of America. RECENT LITERATURE. THREE CRUISES OF THE BLAKE.'—In recent years American work in marine exploration has been overshadowed by the promi- nence given to the celebrated Voyage of the “Challenger,” while the magnificent manner in which the scientific results of that voyage have been published by Her Majesty’s Government is unrivalled. Still, American science is doing much to unrayel the secrets of the sea, and the investigations of the Fish Commission and of „the Coast Survey stand second only to those of the “Challenger” 1m their importance. In the two volumes by Mr. Agassiz we have a popular account of the results of the Cruises of the Coast Survey Steamer “ Blake, which is entitled to rank with the accounts of Moseley, Spry, = even of Wyville Thompson, of the Voyage of the “ Challenger, ree Cruises of the United States Coast and Geodetic Survey Steamer “ Blake” in the Gulf of Mexico, in the Caribbean Sea and along the Atlantic Coast of the United States, from 1877 to 1880.

Aside from the numerous maps, the illustrations have been mostly made by some of the photo-engraving processes, and the perfection to which these have arrived may be seen from the figures which accompany this notice, ` Passing by the chapters which give a history of the progress of eep-sea investigation and that detailing the special equipment of the “ Blake,” a small three-hundred ton steamers—for the work, we Goes account of the strange and bizarre creatures inhabiting those epths.

Holme recently read to the Royal Geographical Society an interesting account of a journey to the interior of Labrador. Although the coast is utterly bare and treeless, a luxurious forest growth commences at a distance inland of about twelve miles, and clothes the whole of the country except the barrens or moors, which are the home of the caribou. Mr. Holme has ascended all the rivers that flow into Hamilton Inlet as far as navigable in a boat. One of the most important of these is the Kenamou, used as one of the routes from ‘the south. By far the largest river of this district is the Grand, which is the name given to the channel connecting Lake Petchika- pou with Goose Bay, at the head of Hamilton Inlet. Grand River is really only a portion of a continuous water-way of rivers and lakes con- necting Goose Bay with Ungava Bay. Lake Wiminikapou is situated about 150 miles from the mouth of Grand River, and thirty miles above that long and narrow lake are the Grand Falls, the height of which is not known, but which may prove to be among the most stupendous in the world. The elevation of the Labrador table-land is given by Professor Hind at 2240 feet, and at least 2000 feet of this are in the thirty miles between the head of these falls and the lake below. Lake Petchikapou, one of the largest of the interior lakes of Eastern Labrador, is connected with the ocean not only by Gran River, but by Nascopee River and Grand Lake. The Indians of the interior of Labrador are all of the Cree nation, and are perhaps the most unadulterated Indians to be found on the continent. G. Guillemard, in a note to the May number of the Proc. Roy. g. Soc. suggests that possibly the Grand Falls of Grand River (Labrador) might be reached more readily by following up the Moisie River from the Gulf of St. Lawrence and skirting Lake Aswanipi. He also says: “ The fall from a height at all approach- ing 2000 feet of a river 500 yards in width a short distance higher up, would form one of the wonders of the world, and would surely have been described by Mr. Maclean after returning from his visit in 1839. Mr. Guillemard mentions among waterfalls combining reat volume of water and great height, the Garsoppa a Western Hindostan, 300 yards wide and 830 feet high, and the Kaieteur Fall of the Potaro River in British Guiana, 123 yards wide and 741 feet in vertical height. 1 Edited by W. N. Lockington, Philadelphia, Pa. Geography and Travel. 521 RAINFALL WEST OF THE Mississrpp1.—General A. W. Greely recently gave to the Washington Philosophical Society the partial results of the charting of recent observations on the rainfall west of the Mississippi. The number of observing stations has been doubled during the past ten years, and the result of the observations has been to greatly reduce the areas of small rainfall. The area in which less than fifteen inches per annum was supposed to fall has been diminished one quarter of a million of square miles since the census map of 1880. In some places where the precipitation was supposed to be five inches or less the actual rainfall is as much as sixteen inches and in one spot was found to be thirty-seven inches. General Greely explained that the small average of rainfall formerly reported in Southern California, was partly due to the fact that most of the observing stations were situated on the line of the Pacific Railroad which, seeking low gradients, had been built through a section of the country where the precipitation wassmall. General reely, moreover, thinks that the prevalent opinion that the rain- fall in the West is increasing, is correct. ASIA.—THE Provinces or Kars AND SEMIRECHINSK.— ‘corundum is brought to the surface myriads of small rubies glitter in the sun.

The district of Mogok is situated between Mandalay and Bhamo and is nearer to the former place. THE Brrps’ Nest Isuanps.—The records of the Geological Survey of India (vol. xxi. pt. 1) have some information concerning the remarkable group of islands called by the Burman’s Ye-ei-gnet thaik or Seabirds’ Nests. These islands consist of six marble rocks to the southeast of Dumel Island at the southern extremity of Burma. The largest is a thousand feet high, about a mile in length, and of an oval shape. The great feature of the group are the birds nests caverns, which as a rule open into the sea. In other parts of the island are great caverns opening into circular basins, an mander A. Carpenter, who writes the account, states his impression that these circular basins were at one time the floors of huge caverns, and that in past times the islands were far higher, with cavern over cavern. Arrica.—TuHEe TRANSVAAL.—The configuration of the Trans- vaal Republic, according to Dr. A. Schank, is determined by mountain ranges; the Drakensberg range rises to a height of 7000 feet and traverses the country from North to South, presenting a steep declivity on the East and a gradually sloping table land on the West. The Eastern and smaller part of the Transvaal consists mainly of a series of low granite mountains. A series of parallel chains extend east and west through the country and divide it into a southern portion (the Hooge Veld) and a less elevated northern portion (the Bosch Veld). The former is connected with the plateau of the Drakensberg and enjoys one of the healthiest climates in the world. Van QGÈLE’S ASCENT OF THE Mopanet.—The “ Mouvement and watch-posts are established in the cotton-trees. As far as 7 in the middle of the cataracts the natives have their heads shay Geography and Travel. 523. About twelve miles above this rapid (21° 30’ E. lon.) the Bangasso: discharges into the right bank of the Mobangi. Up to this point the natives had invariably been friendly, offering for sale all kinds of provisions, but here difficulties began. The Mombongo and Takoma tribes which inhabit both banks were decidedly hostile, so, as the navigation was obstructed by rocks and sandbanks, Van reached 22° 55’ on the Welle, and as both points are in 4° 20’ N. lat., there can be little doubt of the identity of the Welle and Mobangi. GEOGRAPHICAL News.—Another voyage made by Dr. Schrader up the Empress Augusta River (New Guinea) confirms his previous opinion as to the important character of this waterway, which probably rises within the Dutch portion of the island, since the amoa reached a spot distant but a few miles from the boundary line, and 380 miles from the mouth of the river. Not only the main river, but several of its affluents, are navigable for long dis- ces during the rainy season. : M. Gamak, a Russian traveler, has recently explored the Khin- gan range, which divides Mongolia from Manchuria. He has tg the range four times and has explored almost its whole M.

C. Selong’ explorations in the Matabele and Mashuna countries, giving the routes of the various rivers and the posi- tion of the hill ranges with greater accuracy than any other previ- ous map. The death is announced of the celebrated Russian, Nicholas von Miklucho-Maclay, whose name has so long been prominent in connection with explorations in New Guinea. His residence in that country impaired his health, and in 1882 he returned to Russia. After this he resided awhile in Sydney (Australia) where he founded a biological station, and then again returned to Russia, where he resided at the time of his death, at the age of forty-two years. GEOLOGY AND PALAZONTOLOGY. GEOLOGICAL News.—Siiurian, ETC.—Dr. John Walther, in his researches into the structure of the crinoids (Paleontographica, Band 32), traces the entire group to a bilateral ancestral form, rep- resented by the Pelmatozoa of the Pre-Cambrian, and considers the Ateleocystites of the Lower Silurian as a reversion to this ancestral and larval form. This is followed by an “acyclical” holosym- metrical form, exemplified by Macrocystella, the oldest Cambrian Pelmatozoan. From this form two series arise—on one hand, the Cystoids, on the other, the Crinoidea. Drvontan.—M. Maurice Gordon has discovered in the Valley of l’Arboust, in the Pyrenees, a schistose deposit with trilobites which are entirely new to the French fauna and ascend to an epoch that has recently been studied between the Hartz and the Ural. These trilobites include two new species of Bronteus and one each of Dalmanites, Lichas, Cyphaspis, and Harpes. M. Chas. Barrois states that the fauna is more recent than the Silurian stage of Bohemia and older than the Coblencian stage of the Devonian. , M. Chas. Barrois has identified twenty-eight species of crinoids, brachiopods, trilobites, etc., occurring in the singular sedimentary limestone of the quarry of Vallet, near Chaudefonds (France). Though this thin bed is certainly Devonian, it has not yet been cor- related with the other Devonian bands of the region, but seems to form an islet in the midst of red and green schists, which are by some referred to the Lower Silurian, by others to the Upper Devonian, or even to the Carboniferous. The trilobites are Seas but the brachiopods and crinoids are Devonian, and the fossils, a8 Geology and Paleontology. 525 whole, are referred by M. Barrois to the same horizon with the Eifelian beds of the Rhine. The coral limestone of Cabrieres (Herault, France) is by M. Bar- rois ranged between the Eifelian and the Coblencian stages of the evonian CARBONIFEROUS.—Spirodomus insignis, is a peculiar, spirally- twisted lamellibranch, recently described by Chas. E. Beecher, from the attenuated Waverly series of northwestern Pennsylvania. In its reflexed and minutely plicated margins and absence of proper hinge, this shell-suggests some forms of Pholas, and its spiral form seems to indicate a burrowing habit. Among the impressions of fishes collected in the shales of the coal-beds of Commentry are some with a cartilaginous skeleton ossified at certain points and presenting peculiarities not to be found in any other living or extinct fish. The study of twenty-three examples of this fish, some of them in a good state of preservation, has enabled M. Brongniart to describe it under the name of Pleura- canthus gaudryi. In form this fish resembles a shark, and in length it varies from eighteen to forty inches. Jurassic.—Dr, E. Fraas (Paleontographica, Band 32) treats of the asteriads of the White Jura of Swabia and Franconia, with re- searches into the structure of echinoderms and the skeleton of the Asteroidea. He describes as new Astropecten infirmum and A ans; also Pentacerus pustuliferus, from the lithographic schists of Kelheim. __E. Koken (Paleont. Abhandl., 1887) has contributed additional information upon the Dinosauria, Crocodilia, and Sauropterygia of the Wealden of Northern Germany. Among the crocodiles, Gonio- pholis pugnax and G. minor, and among the Sauropterygia, Plesio- saurus degenhardti, Pl, limnophilus, and a third unnamed Plesio- Saurus, are new. The work also contains much information upon the development of the brain and auditory passages of the genus Macrorhynchus. ; CRETACEOUs.— Gigantichthys pharao is the name given to a fos- sil fish of the family Trichiuride, collected by Professor Schwein- urth in the cretaceous beds of Egypt, within ten kilometres of the Pyramids of Gizeh. Cxnozo1c.—Dr. O. Roger concludes (Ueber Dinotherium bavari- cum, Palwontographica, Band 32) that D. bavaricum is the smaller, older ancestral form, contemporary with Anchitherium, out of which, y a series of transitional forms, the gigantic Din. giganteum Was finally developed in the Hipparion period. : In 1885 Professor M. Neumayr and Dr. I.. v. Tausch undertook explorations in the Pliocene beds of Pikermi, near Athens, for the- 526 General Notes. benefit of the Vienna Museum, and the result of their work has been to considerably widen our knowledge of that rich fauna. Dr. A. Weithofer describes as new Mustela paleattica, Machairodus schlosseri, Camelopardalis parva, Helicoceras rotundicorne, an Varanus marathonensis, and mentions some avian remains of as yet undetermined forms, two of which seem to belong to the genus Gallus. A species of Felis, mentioned but not described by Gaudry in 1862 as at least equal in size to the largest jaguar, is by Dr. Weithofer described as F. leiodon. Helicoceras rotundicorne is a gazelle-like antelope with rather large and spiial horns. A. S. Woodward (Geol. Mag., July, 1887) describes Arius eger- toni and A. (?) bartonensis, two forms of siluroids from the Middle and Upper Eocene beds of Bracklesham and Barton (England). Van Beneden (Zeitschr. deutsch. geol., Ges. 1887) has described Cetacean remains from the northern slopes of the Caucasus. These remains probably belong to the genera Squalodon and Cetotherium. The age is Upper Miocene. PLEISTOCENE.—The exploration of the caves in the Karnul dis- trict of Madras, conducted by Mr. R. B. Foote, has resulted in the finding of about forty species of Mammalia, of which Mr. R. Ly- dekker (Mem. Geol. Surv., India, Ser. X., Vol. IV., Pt. 2) describes as new Viverra karnuliensis, Hystrix crassidens, Atherwra karnuli- ensis, Rhinoceros karnuliensis, and Sus karnuliensis. The most important of the Karnul caves are those of Billa Surgam, which consist of three short and deep cafions joined by natural arches, and with caves opening into them at various levels. The comparatively wee number of extinct forms and forms not now to be found in India that occur in these deposits renders it probable that they are malian fauna that has been recently found at Voklinshofen, one Colmar. Twenty-nine forms are listed, most of them ne oes u or in the Alps. Mineralogy and Petrography. 527 MINERALOGY AND PETROGRAPHY:.! PETROGRAPHICAL News.—In a preliminary notice of the rocks occurring in the neighborhood of Ilchester, Howard county, Md., Mr. Hobbs? describes some interesting features of the eruptive masses of the region. The oldest rock within the area studied is a hypersthene-gabbro with its associated alteration products.? In the gabbro diorite, originating by dynamic metamorphism from the massive hypersthene-gabbro, ilmenite and rutile are found to be so associated with sphene as to lead the author to regard the rutile as an intermediate product in the alteration of ilmenite to sphene. The end product in the alteration of the gabbro is a typical horn- blende-gneiss, in which peripheral granulation of the original feld- Spar can be detected. A quartz-mica-diorite, in which the quartz is in porphyritic crystals, contains about equal proportions of orthoclase and plagioclase. The most common form of granite, cutting the gabbros and allied rocks, is a coarse pegmatite in which microcline crystals a foot in diameter are sometimes observed. varieties. The former consists of a glassy type, in which certain dark particles group themselves so as to produce patches of a ` dark color on a background of light-colored glass, without the production of a true globulitic or spherulitic structure. In the radiolitic variety devitrification products are divergently arranged around a centre.—The nodules of the coarse granite at Ghistorrai, consisting of triclinic soda-feldspar and biotite, in centric layers.

Since pyrite does not occur in meteorites, and since, more- over, these little graphite pieces are entirely surrounded by metallic iron, Fletcher thinks that their shape must be original, and that this substance is truly regular in crystallization. CRYSTALLOGRAPHIC News.—It has been known for a long time past that the natural conclusions to be drawn from the Bravais- Mallard theory of cleavage planes and erystal structure, based upon the point system of explaining crystallization, have not been borne out by the facts. As a consequence of this theory it is demanded that the planes of easiest cleavage in a mineral should be parallel to those planes which are most commonly present on it and best developed. This is known, however, not to be the case. Sohncke?* explains how these difficulties can be met by modifying the theory of the point system, as pointed out by him in recent* papers. —The same subject is further discussed by Wulff,> who takes up the dif- ferent crystallographic systems in detail, describes in terms of the eory the inner structure of minerals crystallizing in each, and orms on the crystals examined, among them the new forms 4 Pœ, 2 P35 P5,-3 P36 P 3 and3 Pj (a: 6: ¢ = 1.2657 : 1 : 6354 pix 89° 51’).

Moreover, he finds that the absorption axes—the direc- tions in which the greatest, the least and the mean absorption takes place—do not correspond with the axes of greatest, least and mean elasticity, as had already been indicated by earlier observa- tions. The direction of greatest absorption for the red ray in the clinopinacoid is inclined 28° to the axis of least elasticity, while ‘concludes (1) that one of the absorption axes in monoclinic erys- tals coincides with the axis of symmetry b, while the other two lying in the plane of symmetry do not necessarily coincide with the axes of elasticity for the same color. In triclinic minerals there is no accordance between the absorption axes and the axes of elasticity. (2) The axes of greatest and of least absorption for any given color in triclinic minerals and the absorption axes lying in the plane of symmetry of monoclinic minerals are not always perpendicular to each other, as are the axes of elasticity.—The same subject is discussed mathematically by Drude,’ who calcu- lates the positions of absorption maxima in monoclinic and tri- clinic minerals from data obtained by Ramsay. He finds slight discordances between the observations of Ramsay and the theo- retical demands, but concludes that, on the whole, Voight’s* the- ory of absorption is substantiated—By supplying a blast lamp with warm air and with oxygen, Specia® has sticceeded in fusing many of the minerals infusible under ordinary conditions. The differences in their conduct under these changed conditions may glass when oxygen is used. Colorless topaz is difficultly fusibl in the first case, while it fuses readily with intumescence in the sec- ond case. Colorless zircon is infusible in both cases, but ponpon cloudy at the high temperature produced by the combustion wit) oxygen. 1 Zeits. f. Kryst., xiii., 1887, p. 161. ; 2 Zeits. f.

Botany. 531 BOTANY.” AN OVERLOOKED Fuxcriox or Many Frurts.— It is a matter of common observation that many fruits (carpels) are green in color for a considerable period after the fertilization of the ovules, but I am not aware that particular attention has been called to the signifi- cance of this fact. Different botanical authors mention, incidentally as it were, the fact that as long as the young fruits are green they, of course, perform the functions of leaves, by the fixation of carbon in the process of assimilation. All such statements, however, take e Box Elder (Negundo aceroides Moench) develops its fruits tis later, but they take on likewise a rich green color, and in the atter part of May in some instances add fully fifty per cent. to the assimilating surface of the tree. Maples, Ashes, and even Poplars and Willows, the latter to a less degree, present the same phe- nomena, and in fact, in by far the greater number of instances the or ae of the fruit for aid in the work of assimilation is the rule. “tie the Pines and their allies the development of chlorophyll- ing tissue is confined to the scales of the cone.

A DEPAUPERATE GRass.—The accompanying illustrations (Figs. 1 and 2) show a depauperate individual of Sporobolus vagineeflorus, found entangled in the roots of a Solidago which was collected on the high prairie a few miles southwest of Lincoln. This little grass had three flowers, two of which had ripened seeds. The lower one of the three was still included in the upper leaf sheath. The sod from which the speci- men was taken was formed of Stipa spartea, Andropogon provin- cialis, A. scoparius and Boutelowa | racemosa, and a close observer would find no trace of the Sporobo- lus. In fact, S. vaginæflorus does not appear on the uplands except where the ground has been broken by natural or artificial agencies. The presence of this single speci- Fre, 2-A spike- men clinging to the roots of alsa ien diam- high prairie denizen is of great sig- eters. nificance in explaining its apparently sudden appearance on gopher mounds and along culti- ted fields. od bein et Fig. 1.—Plant of Sporo- bolus vaginæflorus Torr., Va natural size, club of the term Anthophyta for the Flowering plants.—The Proceedings of the Forestry Convention, held in Grand Rapids, Michigan, January 26 and 27, 1888, has been published in A pamphlet of sixty pages, and contains along with much indifferen matter some which has value.—In marked contrast with the ae going in the treatment of the subject are the “ Lectures on Fores and Forest Products,’ given by Dr. G.

Hist. Soc., vol. i., pp. 71-44, pls. xiii., 1888), an extended catalogue of all the known Species in the United States. Even his own papers appeared in so many places that it was rapidly becoming impossible to keep track of them all. In the present catalogue 351 species are enumerated, distributed as follows :— Flagellata 153 Monadina...... 27 MARLON ONG, -sss eo eiessirie irot ae ed 46 EP Py tig 2) es FU tig s : 24 Gboano-flarellatá. >i kaaore err 30 Dino-flagellata 3 Cilio-flagellata 3 Ciliata ...... i 268 Holotricha 58 js Pe pea ar ae 99 Peritricha 122 EEA o 5 cicecscvcced eee oie caiaderne ae Suctoria. 7ps 30 Sa will be noticed that Dr. Stokes accepts both the Cilio- and the no-flagellata, contrary to the recent classifications. reaso 534 General Notes. are that while there is a second flagellum in some of the Peridi- nidæ, in others of the old group of Cilio-flagellates there are true cilia in the equatorial grove or scattered over the surface of the and hence the group must be retained. It is interesting to note that while Dr. Stokes has given names to nearly 250 new species of Infusoria in his various papers, he has carefully refrained from adding to the number in the present contribution. Two Cases or SymMmBIosIs.—Dr. ©. P. Sluiter notices two instances of “ mutualismus ” as occurring in the seas of Batavia. In shallow water there is found a large sea anemone (Actinia) protection from enemies among the tentacles. In one case, Dr. Sluiter removed several fish from their protector and placed them in an aquarium with several larger fishes. The little ones tried their best to hide among the corals and the spines of the echino- derms, but soon fell victims to the appetites of their cousins. hers placed under similar conditions, but in company wii anemones, survived for over half a year. ey prove very timid, and rarely venture but a short distance from home.

The cells of the typhlosole not only absorb the digestive juices, but they also have a digestive function much like that of the pancreas of the Vertebrates. „Other observations relate to the histology of the epidermis, the pigment material, the œsophageal muscles and the calc glands. Some notes are made on the distribution of the Russian species, two of which occur even in the Lena Delta. Recent Nores on SCAPHIOPUS HOLBROOKII.—The eneral characteristics of this animal have been long and familiarly known and its more prominent anatomical features clearly defined ; but its rather circumscribed distribution and comparative rarety, even where known to exist, have made somewhat difficult any extensive study of its peculiar nature and habits. : summer on Martha’s Vineyard, and the occasion of a sudden. and tremendous rainfall, afforded an opportunity for certain very interesting observations. . : a If the literature of the subject is any indication as to its famili- arity, the submission of the following notes may not seem a work of supererrogation ; for, aside from the studies of Dr. Chas. C. Abbott, published in Vol. XVIII, No. 11, of the Am. NATURALIST, and those of Colonel Nicolas Pike, published in Vol. I, No. 7, of the Bulletin of the American Museum of Natural mon, I have not been able to find anything except brief notes, scattered in miscella- neous works, though I believe notes on its occurrence have been e by Mr. Nichols and by Mr. Fred. S. Smith. ; My observations, as will be seen, add but little that is new ; yet a record of them may contribute somewhat to corroborate and extend that which does exist. : One afternoon, about August 10, 1887, while at work in the laboratory of the Martha’s Vineyard Summer Institute, in com- hours or more, uring an interval of cessation our attention was diverted by weird, plaintive sort of cries, which none at first was able to explain. Darting out through the still-falling rain toward a low Sort of hollow, from which the cries seemed to come, it was found to have been converted into quite a pond, though previously quite dry. In this, and swimming about in a state of the greatest activity and excitement, were what looked to be scores of toads. Nod culty was found in securing a few specimens, which were at once mentified as “ spatlefoots.” ~ Procuring a scoop-net, we took several dozens of them, leaving many more in the : ee S was about four o’clock in the afternoon, and they continued 536 General Notes. their orgies till late at night. But I made carefu) examination the following morning, withcut finding a single specimen—not even a sign of one. Inthe water I found plenty of the spawn attached to rass and floating in strings, loosely attached to weeds—a fact which clearly indicated the purpose of their presence and peculiar excitement. n account of the pressure of other studies, I was not able to watch the development of the eggs. Indeed, I doubt whether they ever hatched, as the pond was nearly dry before the close of the fol- lowing day, and the soil, being of the loose sandy drift peculiar to that locality, would not certainly retain water for sufficient time for the growth of the tadpole—if, indeed, for the hatching of the eggs, though, as to this last, I cannot say, as I left before it could have occurred. This characteristic of the spawning habit is certainly peculiar, and seems somewhat difficult to explain. First, the lateness of the season is remarkable. It is said that a related European species breeds twice a year. Can it be possible that such is the case with _Scaphiopus? There are some facts which seem to indicate that it might be, though it is hardly probable. Second, the places of spawning is still more remarkable. From the observations of Dr. Abbott and Colonel Pike, as well as my own, the choice seems to be for some temporary sink-hole or surface-pond. If the conditions for development in these places from speedy drainage, etc., were no so utterly precarious, it might be thought a shrewd precaution for evading the natural enemies common in the more permanent ponds and bogs. Altogether, the case seems to be quite anomalous. But to refer again to the adults in the pond: There they were by scores. Whence had they come, and in such numbers? In all probabilities, from the ground of the bordering hillsides and environs. But not a single specimen was seen out of the water, and that, too, notwithstanding we were at the pond almost 1mme- diately following their first coming. If they had come from any tolerable distance, it would seem that some late-comers would have been detected. Again, their retreat must have been almost as sud- den as their appearance. I passed the pond about ten o’clock at Such seems the most probable explanation. Yet so carefully they covered the retreat that not the slightest trace could be found. Furthermore, their appearance itself seems to be capricious and vant habits as to able to find any account of them. ker It las been suggested that they are, doubtless, nocturnal ap sin and that this explains, in a measure, their comparative rarity, br where known to exist. I have no hesitancy in assenting tO Zoology. 537 nocturnal habit. It is quite in keeping with the habit of many of the order; and the vertical pupil of the eye points likewise to the same fact. This, however, in itself, must be a comparatively small factor in the case, and, alone, would hardly insure it against frequent detection any more than does a similar habit in many other noctur- nal animals. I had gone by this hollow repeatedly, night after night, both before and after this appearance, and, though constantly on the alert to notice anything of the sort, had no hint of their presence. Doubtless, the solitary burrowing habit goes much further in explaining its seclusion. But even this would be inadequate, unless the animal persistently avoided all open and cultivated grounds. age only, would protect it against frequent exposure by the spade or plow. Altogether, they are certainly the most peculiar and erratic of any of the order; and, under the peculiar difficulties in the way of continuous study, it will be long ere its life-history can be said to be thoroughly known. However, the very difficulties add a charm to the investigation, which we may hope will lead to success. To me, the brief research herein outlined has been full of the liveliest interest, and, while but a mite toward the solution of the problem, I shall hope that it may not be without some value when a final summary is made.— C. W. Hargitt, Moores Hill, Ind. Tae RELATIVE WEIGHT OF THE BRAIN TO THE BODY IN Biros. — In a former number of the AMERICAN NAT- URALIST,' notice was made of the relative weight of the brain to the body in Spizella socialis, and Regulus satrapa compared to that of man. Since that time more extended investigation has been made, with a view of ascertaining the relative weight of the brain to the body in different species of birds, the result of which is appended below. An interesting fact dey eloped from these figures is that there is considerable individual variation in the weight of the body an brain in different individuals of the same species ;” this is no doubt ependent in some way upon the time of year, the amount of food supply, and individual idiosyneracy ;° there is no sexual distinction 1m regard to the relative weight of the brain to the body—but, on the contrary, male and female alike offer marked degrees of fluctu- ation in this regard. Exception, however, exists in the two speci- mens of different sexes of _Harporhynchus rufus, which closely coin- cide in their relative weights. ost of the specimens considered here were taken at Grand Crossing, Illinois, the remaining ones in Chicago.

It takes twelve of these dust shot, by actual count, to equal a grain weight, and advantage of this fact was taken into account in estimating the weight of the shot that passed through the skin of the specimens, and subse- quently deducting this after the weights of the individual had been taken. This was obviously of little importance in the ultimate result; however, every precaution was taken to avoid errors. The weight of the brain and body are given separately, and the relative weight of the former to the latter, all the weights being designated in grains, as a matter of simplicity. In the weighing of the speci- mens the bird with all its parts intact was laid upon the scale-pan of a prescription scale similar to those used in apothecary stores, which weigh accurately to half of a grain. After being weighed and noted, the brain of the specimen was carefully removed + by making a circular incision, and the removal of the piece of bone, thereby cut free, from the posterior part of the cranium by means of a small scalpel. The opening that remains after the operation being sufficiently large to admit of the withdrawal of the entire encephalon after the optic nerves have been severed and the spinal cord likewise treated below the medulla oblongata. After the brain was removed in this way it was weighed upon a more delicate sad- dle-back scale, which weighed accurately as low as the tenth of a grain. Forty-seven birds were thus weighed, and for purpose 0 comparison with some small mammals four adult specimens of the common house mouse, Mus musculus, and one specimen of common gopher, Spermophilus tredecimlineatus, are reckoned. 5 > i Op Weight | Weight Bee gee Name of Specimen. of of |Sex.

Ihave frequently observed an ingenious device, to serve as an apparatus for aquatic ‘esplration, resorted to by the animal when driven from its burrow eh pond frozen over. In attempting to cross the pond under the ice, if the pond is too wide for the muskrat to “ hold its breath” 540 General Notes. until it reaches the opposite shore, it will stop for a few moments and exhale the air which is held down by the ice. Interchange of gases takes place between the air and water, when the animal re- breathes the air and makes another start, repeating the act until the shore is reached. I do not claim this as an original observation ; others than myself have noticed it. It is well known by those who have observed the phenomenon that if the ice is struck immediately above the air, and the air thus scattered into numerous bubbles, the muskrat drowns. Having noticed an account by Professor Com- stock of the use, by the “ water boatman ” of a bubble of air for a tracheal gill,! I would call attention to this interesting feature in the physiology of respiration of the muskrat.— W. L. Spoon, Univ. N. C., May 1, 1888. ZOOLOGICAL News.—CaLENTERATES.—Dr. G. Hubert Fowler, in the fourth part of his papers on the anatomy of the Madrepora- ria (Q. J. Ms., 1888) discusses the structure and systematic positions of the genera Madracis, Amphihelia, Stephanophyllia, Stephanotro- chus, Stephanaria, Pocillopora and Seriatopora. e points made are mostly of minor importance, except that certain cells described as coral-forming (calycoblastic) cells, occurring in several genera really function to hold the mesenteries more firmly to the corallum. ECHINODERMATA. — The number of species of Asteroids col- lectd by the French scientific expedition to Cape Horn is thirty- eight, twenty-three of which are new, while thirty-two were not represented in the museum of the Jardin des Plantes. The num- ber of species known from the southern point of the American con- tinent now reaches fifty-seven. M. E. Perrier finds great variabil- ity in each species, correlated with the varying conditions under which they exist. Wor{s.—Beddard describes (Quart. Jour. Micro.

The species Trochus have a southern distribution. CrustaceaA.—Another part of Dr. De Man’s Crustacea of the Mergui Archipelago has appeared, embracing pages 177 to 240, and plates 13 to 15. It includes the conclusion of the Grapside, the Leucosoids and the major part of the so-called Anomura. The series is especially valuable from the fact that the author has had access to the types of the French carcinologists. So far the species enumerated number 135. M. Chevreux and Guerne call attention to the amphipod, Cyrtophewm chelonophilum, a commensal. of Thalassochelys caretta, seventy-seven specimens of which have been collected in the scien- tific voyages of the Prince of Monaco. This species differs from those previously known by the shortness of the antenne, and is. probably a native of both hemispheres. After Rathke, in 1837, noticed the curious fact that the Palæ- mons infested by Bopyrus belonged exclusively to the female sex, all succeeding authors have confirmed his observations. Neverthe- less, guided by previous discoveries concerning the effects of para- sitie castration among certain decapodous crustaceans infested by the Rhizocephala, M. Giard last year gave forth the hypothesis. that the facts noticed by Rathke were true in appearance only, and that though all the Palzemons fount with Bopyrus seem to be of he female sex, this was really the result of the atrophy of the male organ produced by the parasites. M. Giard has recently been able vee this supposition, both on European and other species of æmon. ; „MYRIAroDs.—C. H. Bollman publishes in a small pamphlet Without indication of place of publication, a preliminary list of the Myriapods of Arkansas. Forty species are catalogued, of which nine are regarded as new. + FisuEs.—Mr. George Brook (Proc. Royal Phys. Socy. of Edin- burgh, x.) monographs the British species of the genus Zeugopterus, enumerating three species, Z. punctatus, unimaculatus, and papillo- sus, the last being a new species found in the Clyde. Mr. Geo. Brook (Proc. Roy. Soc. Edinburgh, 1887) states that in the trout the segmental duct arises from the ectoderm. Its first appearance is in an embryo of twenty-seven days, when it forms a. well-marked thickening in the middle trunk region. The lumen of the duct arises as an irregular cavity, and later the whole tube sepa- cites from the ectoderm and sinks into the intermediate cell mass, Far observations that he has made on the chick seem to indicate- ^at a similar origin of the duct occurs in birds. According to the observations upon the food of fresh-water- 542 General Notes. fishes, made by S. A. Forbes, and forming Article VII. of Vol. III. of the Bull Ill. State Lab. of Nat. Hist., eighty-three per cent of the food of the burbot consists of fishes, while Esox lucius takes ninety-nine per cent. of fishy food. Dorosoma feeds chiefly on fine mud containing about twenty per cent. of vegetable debris; the golden shad principally on fish; and the Catostomide, fifteen species of which occur in Illinois, consume molluscs and insects almost in equal ratio. The stone roller (Hypentelium), which in its habits simulates the Etheostomatide, feeds, like the members of that family, almost solely upon the larve of aquatic insects. The cat-fishes are nearly omnivorous, and are the only habitual scaven- gers among the common fishes of Illinois. Amia seems to feed upon Crustacea, fishes, and molluses, with very little mixture of insect food ; the gars entirely on fishes; and the singular Polyo- don chiefly upon minute insects and crustaceans, especially the former. Professor Forbes thinks it probable that Polyodon employs its paddle-like snout to stir up the weeds as it advances along the muddy bottom, thus driving the animal forms within reach of its branchial strainer, while the mud and vegetation have time to settle. : Though in the deep-sea fish-fauna no distinct bathymetrical zones, characterized by peculiar forms, can, according to the “Report on the Scientific Results of the Voyage of H. M. §. Challenger,” be defined, the abundance of fish-life decreases with the depth, as is shown by the number of species (232) found between 100 and 300 fathoms, as compared with 142 between 300 and 500 fathoms, 7 between 500 and 700, 56 between 700 anc 1500, 24 between 1500 and 2000, and 23 below 2000 fathoms. Partially grown examples of several species of freshwater ` fishes have recently been successfully introduced into Chili from France. The principles followed in arranging the methods for this long transport, involving five changes previous accommodation of the water-cylinders on the steamer Sarata, were as follows: (1) The preservation of the same water. (2) Absence of alimentation. (8) Refrigeration. (4) Continual circulation of air.

The only new form described is Crotalus palmeri, from Monclova, Mex- ico, which the author regards as a variety of C. tigris, though he has not applied to it the trinomial system he advocated a few years ago. Fred A. Lucas discourses the ever-new question, “Do snakes charm?” in the third number of the Journal Trenton Nat. His. Soc. He concludes that the whole effect lies in the person, and that it is no property of the snake. The warts which appear at certain seasons upon many males of Rana temporaria, form the subject of a communication to the Zeit- schrift für Wissenschaftliche Zoologie, 1887, by O. Huber. Among the reptiles of Noronha are a species of Amphisbzna, a skink (Huprepes punctatus) and a gecko. Batrachians and fresh-water fish are absent. , According to G. B. Howes, the low rank assigned the Discoglos- side, by Cope, receives confirmation in the distribution of the azygos veins.

Eight forms occur only in Asia Minor and its coast islands. M. Dollo attacks the conclusion of Dr. Baur that the Athece (Sphargis, ete.,) are descended from the Thecophora. He argues that if the carapace of the Athecz is formed, as maintained by Dr. Batır, by delamination into a mosaic of the carapace of a Thecopho- rous ancestor, fontanelles ought to exist as in the other Chelonians, which is not the case. Moreover, the oldest genera of were without dorsal armor. The fact that the plastron of Sphargis is more reduced than that of the other Chelonians goes indeed to show that the Thecophora cannot be descended from the Athece, but it does not indicate the reverse of this. Dr. Trouessart, from various considerations, inclines to the belief that the two groups have descended from a common ancestor by diverging paths. Brrps.—George F.

The two specimens which I collected deceived me at first, but a few threads of silk led me to make the examination. The spider seemed so confident of its protection that it would not move when I jarred the plant, strik- ing it several hard blows. I pulled the spider forcibly from the leaf, and it did not exhibit any signs of movement until transferred to the cyanide bottle. The cocoons which I have found here are also protected by mimicry. They are essentially like those of Cyr- tarachne bisaccata Emert.! They are dark brown, about 12 mm. in diameter, and are provided on two opposite sides with stems made of the same colored silk, about 5 mm. in diameter.

There seems good reason, however, for believing that very nearly all desert their tubes during the spring and summer, at times, and wander in search of their prey. Indeed, there are indications that there are latitudinal, as well as seasonal variations in the habits of the family, i.e. that in northern latitudes proportionately a greater number make no tubes than in southern latitudes. The latitudinal variation might be called generic, in that many species of the genus in north- ern latitudes hide away under stones, etc., making no tubes at all ; while in southern latitudes many other species of the same genus construct tubes, some few using them habitually; many others temporarily. On the other hand, the seasonal variation might be called specific, in that most species, in any latitude, which construct tubes use them only during inclement seasons, or during periods of weakness. One species I have observed here, Lycosa fatifera Hentz, habitually uses its tube at all seasons; never, or very rarely, wandering in search of prey. I have many times watched them resting at the opening of the tube, waiting for passing insects. They will dart back into their tubes when alarmed. Hentz reported this species from Massachusetts and Alabama. have made special investigations upon the species in North Caro- lina, with a view to establish, if possible, the identity of Hentz’s Species fatifera, and the correctness of his statement that it uses the tube habitually at all seasons. The species can be easily recog- nized from Hentz’s description. The one I find here is the piceous variety, which Hentz reported from Alabama, and not the typical >i from Massachusetts.— Geo. F.

THE SEVERAL FUNCTIONS OF THE ENAMEL ORGAN IN THE DEVELOPMENT OF THE TEETH OF MAMMALS AND ON THE IN- HERITANCE OF MurILATIoNs.— As long ago as 1880 Dr. A. Von Brunn? called attention to the fact that the cross crests of the crowns of the molars of the common grey rat were not completely covered Mey an enamel coating before eruption.

Ryder, Univ. of Penna,, Philadelphia. _ nen tiz über un vollkommene. Schmelzentwickelung auf den Mahlzäh- pi eenatte Mus decumanus. Arch. f. mik. Anat.

Here and there ragged masses of this tissue seemed to project into the surrounding tissues of the mucous membrane, as if dragged out of place by the gliding of the crowns of these young molar teeth of opposite jaws over each other. These results were obtained from a study of longitudinal sections of recently born rats, with the eye- lids still closed, but with the incisors just breaking through the ums. The great value which the present reviewer attaches to Dr. Von Brunn’s earlier observations does not lie in the new histologi- cal relations established, but in the discovery that the enamel 0 the cross-crests of the crowns of the molars fails to develop in the embryo in a situation corresponding to the point where abrasion in the adult through use has slowly worn away this enamel covering -and exposed the dentine underneath. This mutilation (for such it is, although produced by an exceedingly slow process of wear), has very clearly been transmitted through heredity. That Dr. Von Brunn should have failed to draw this conclusion from his facts is somewhat surprising, and while glad to call attention to his very important observations, the present writer is of the opinion that these discoveries are amongst the most important made during the resent decade as throwing new light upon the method of the evo- lution of organisms. i Ina second memoir! Dr. Von Brunn continues his investiga- tions, and adds greatly to his preceding observations. He finds, 1m act, that in still earlier stages of the enamel organs of the several kinds of teeth are not different from those normally observed im other mammals, as shown by the tooth germs of the incisors of a uterine embryo of the rat 28 mm. in length. The enamel pea ` in this last instance are simply cap or dome-like bodies, in w ich there is as yet no differentiation of the anterior wall as the perma- nent enamel germ of the enamel band on the anterior face of the incisors of the adult. This is clear proof that profound changes must be suffered by the enamel organ from its earliest appearance until its full differentiation, portions of which evidently must later become either functionless or acquire a new or m ified function. This is just what Von Brunn’s later researches most conclusively prove. They show, in fact, that in the rat the enamel osmi Pi comes functionless across the transverse crests of the molars a eruption, thus leaving the tooth to erupt with its dentine pe ered at those points.

Embryology. 549 forms the enamel of the crowns of the molars develop hard enamel, but the portion which extends down over the root and cervix of the molars undergoes degeneration, and its cells lose their columnar form and degenerate into radiating fibres of considerable length, which send their free ends into the surrounding alveolar perios- teum. These fibres persist even to adult age, and can be readily seen extending from the tooth into the wall of the alveolus in sections of the entire heads of adult white mice (Mus musculus) prepared by the present writer during the last winter. These fibres evidently serve to securely anchor the teeth into the alveolus of the adult, so that the enamel organ is found to have not simply the function usually ascribed to it, but another equally important, namely, the produc- tion of these anchorage fibres. Still deeper down in the alveolus the extreme inferior edge of the cap or dome-like enamel organ Seems to become quite degenerate and functionless. Such function- less marginal portions of the enamel organ are found in the young of man, the ox, and the rat and mouse. The enamel organ is re- garded by Von Brunn in fact as a sort of mould in which the den- tine or pulp covered with odontoblasts assumes a definite form. Von Brunn concludes his second memoir with the observation that he considers that he has shown that in the Mammalia, wherever dentine is developed, that the epithelial sheath or cap concerned ' in the formation of enamel must have first existed. This explains the existence of the enamel organ in the armadillo (Tomes, Q. Jour. Mic. Sci., 1874). The enamel-forming portion of the enamel organ, after eruption of the molars, is, of course, cast off entirely, or at most persis only as the enticula dentis. The portion giving rise to the an- chorage fibres of the root persists, as may be seen in longitudinal sections of the molar teeth of adult animals in place in the jaw. the incisors of the rat, on the contrary, the enamel organ has a more complex history. While it does not differ entirely from the germs of the other teeth in an early stage of development, as all parts of its wall are alike thick, later the anterior wall of this primary enamel organ becomes the persistent enamel organ of the enamel band on the anterior face of the incisors, and thickens, While over the sides and back of the tooth it degenerates and gives rise to the anchorage fibres of these teeth, as shown by Von Brunn, and as confirmed by sections of later stages in my possession enamel organs of the first and second molars are connect y an isthmus, and it is probable that the germs of the second and third molars are also thus joined together. In longitudinal sections of the heads of young mice it is, however, of great interest to note that the cross crests of the upper molars have their apices directed 550 General Notes. backwards and downwards, while the apices of the lower molars slope forward and upward, just as they do in the adult, yet at this stage there has been no enamel or dentine formed. This fact shows that the forms of the crowns are foreshadowed in the germs of the teeth before calcification, and it now becomes possible to assume, for the first time with a reasonable show of -probability, that this forward and rearward deflection of the molars is due to an inherited impress or modification induced by the characteristic mode in which the grinding teeth were used in the Rodentia. Because it may be assumed that the manner in which the teeth are used would slowly affect pattern of the crowns, as the writer first tried to show in his essay “ On the mechanical genesis of tooth-forms” (Proc. Acad. Nat. Sci. Phila., 1878). It follows that if physiologically induced mutilations may be inherited, as the results of Von Brunn seem to demonstrate, it is almost equally certain that mechanically induced changes of form slowly caused by the normal mode in which the teeth were used could be inherited with probably even greater readiness. Dr. W. Xavier Sudduth has shown that the reticulum of the enamel organ becomes thinner at the apex of the young tooth. In this way he has also shown that the membrana adamantina or inner tunic and outer tunic are approximated while the blood vessels from the adjacent connective tissue are pushed toward the enamel organ to supply it with nutriment and probably aid very considera- bly in the rapid deposit of the enamel from above, in just the same way as‘the vascular pulp would supply the conditions for the rapid deposition of the dentine from below. That the enamel organ of the foetus is supplied by a vascular plexus as assumed by Sudduth is, I think, completely demonstrated by the fact that I find a fine vascular plexus in immediate external contact with the persistent enamel organ of the incisor teeth of the adult white mouse. The great value which is to be attached to the fact that abrasions of the enamel of the adult, which have reacted upon the funtion activity of the enamel organ of the embryo rat, so that such mechanically induced alterations could be inherited, does not con- so roo a n appealed to as proving that mutilations could be inherited are without exception artificial; in the remarkable example of the already abraded apices of the molars of young mice and peng ot & This datum, which has until now been wanting, is therefore at last ble proof of the soundness of its principles.

THE RELATION OF WILL TO THE CONSERVATION OF ENERGY.! —It is generally supposed that the designed movements of animals exhibit the quality of design by reason of a direct influence exercised by conscious states. It is supposed that an animal eats and drinks because it feels hungry and thirsty; that it changes its position because it feels that position to be uncomfortable, on account of muscular weariness, unpleasant temperature, or some other reason which is consciously felt by it. Such acts are termed voluntary. They are distinguished from the automatic, which are performed either in the absence of consciousness of them or without that rela- tion of consciousness to them which is seen in the voluntary acts. The peculiar influence exercised by conscious states over acts is termed the will. Ordinary will must be distinguished from “ free will,” since its action is a necessary outcome of “ motives” or rea- sons which pre-exist in the mind ; while “free will” is supposed to Spontaneous in its action. With the latter supposititious faculty I have nothing to do in the present paper. The physiological action of will is as follows, so far as it has been _ possible to trace it. An impression or stimulus received by a sen- sory nerve—generally at the surface of the body—is conveyed by it to the posterior column of the chorda spinalis, and is thence trans- mitted through the optic thalamus. to some point in the gray tissue of the posterior lobe of the cerebral hemisphere. Thence a stimulus 18 conveyed by some of the fibres of the white substance to the anterior ee of the gray cortex. Thence it returns downwards, conducted by white fibres, to the corpus striatum, and thence to the anterior column of the spinal cord. From this the stimulus is con- ducted along the motor nerve to the appropriate muscle, where it reteases energy, the muscle contracts, and the act is performed, Modifications of this general procedure depend on the source of the. original stimulus, whether from an organ of special sense or from an internal organ, etc., and the part towards which the outgoing stimulus is determined. , The locality at which the outgoing stimulus receives its direction 1s evidently in the cells of the cortex of the lateral and anterior part of the hemisphere. This iis evidently the seat of the will. I must here recall the familiar fact that multitudes of acts which- display distinct design are performed by animals without conscious- aos aoe any share in the process. There are reasons for ; believing, owever, that such acts could never have originated ina State of unconsciousness of the actor. I will not enter this subject ! Abstract of a hilosophical Society of Wash- ington, May i. before the Phi mop ' 552 General Notes, fully, but state in brief what the two principal reasons for this belief . The first is that, according to our experience, animals which meet with conditions injurious to life which do not cause them pain speedily succumb and perish. It is incredible that animals not conscious of hunger, thirst, and changes of temperature should not speedily die. Animals not conscious of fear of more powerful ene- mies must be destroyed. The second reason for this opinion is, that all designed acts whose history we can trace are the result of edu- cation. This means, conscious stimuli strong enough to hold the attention and the repetition of movements appropriate to the stimu- they pursue with such unvarying precision. But most—perhaps all—animals have not, in so doing, abnegated consciousness. They generally possess enough to enable them to act intelligently in the resence of new occasions and to acquire new. habits and add to their stock of automatic capacities. This may be better understood by reflecting on the long ages of geologic time during which they have had the opportunity for such education. I add here that it is highly probable that the movements thus inaugurated and perpetuated have been made the conditions of the environment, the active factor in animal evolution, since it is prob- ably due to such action that the organography of animals has been determined. This is the probable source of the origin of those vari- ations on which natural selection acts. And the view that organie evolution is due to the consciousness at the back of automatism has been called the doctrine of Archzsthetism.' From this digression I return to the question of the nature of the act of will. ag The animal organism is a machine for the metamorphosis © energy ; and the evidence is clear that this process is perform strict accordance with the law of the conservation of energy. in The te the food. ced during work by simpler and more stable ones, which are elimin the organism ; while the energy which h up and appears as heat, muscular contractions, thought-force, 1 Origin of the Fittest. Psychology. 553 The animal machine is the most perfect converter of energy known, acting with far less waste than any apparatus of human invention. Every mental act involves conversion or metamorphosis of energy, whether it be a mere sensation or a memory, an emotion, ratiocina- tion or a determination of will. Throughout these processes the law of conservation of energy is necessarily obeyed. But mental acts possess qualities which require further attention in this connec- tion. Mind, as such, is not a form of energy. Reducing mind to its generalized expression,—that one which embraces all its phe- nomena,—viz., consciousness, it is safe to say that its qualities, and hence its definition, are totally distinct from those which we ascribe to, and by which we characterize energy. Energy is motion in one form or another. Consciousness is self-knowledge, from the sim- plest sensation upwards. No two subjects of thought can be more widely diverse. In fact, it is safe to say that all thinkable things are traceable to three sources ;—matter energy, or the motions of matter, and consciousness, or the knowledge which some matter has of itself. But I assumed at the outset of this paper, in common with most other persons, that designed acts are due to the direction and control of currents of energy exercised by conscious states. In this propo- sition there appears to be involved an assumption that in an act of will the law of the conservation of energy is violated. This, indeed, appears at first sight to be the state of the case; and it becomes necessary that we examine most fully into the process. It is not assumed that energy is created by an act of will, but it is supposed that energy is directed. The creation of energy is unthinkable. et us see whether the idea of its direction by some thing which is hot energy is a fact of experience or not. ieving, as I do, that consciousness, and hence will, isa phenomenon of a material tri- dimensional basis, and disclaiming the dualistic idea that conscious- n exercising control of the movements of such ia ieee basis. Having already expressed the belief that it does so, let us look into the lowing law. The ynamic expenditure of an act of will has no dynamic relation to the nature of the decision involved in it. This law may be illustrated as follows, in the case of the lower animals. An animal which is pursued by another may run into a hole or it may ascend a tree for safety. In the two cases totally different sets of muscles are used, The animal, for reasons, elects to use the one Set rather than the other set. Another animal may throw one ear forward to catch a sound rather than the other ear. Mechanisms 554 General Notes. acting from the simplest of motives—not free, of course, but none the less a remarkable property of protoplasm, conscious and unconscious. No inorganic machine can do this. What relations do these decisions bear to the amount of energy expended in the resulting act? A physical movement costs energy, nd ental act costs energy. The mental activity inci- dent to a decision of will costs energy, and the more per- fectly ratiocination is performed, the more perfectly is the energy consumed and the less dissipated, as heat. But does the decision to use the left hand, eye, or ear cost more or less than the decision to use those of the opposite side? Evidently not. Does the decision to climb a tree cost more than the decision to enter a hole? I venture to say that it costs a man no more to decide to build a house than to decide to stand a brick on end, so far as the act itself is concerned. is is because the act is the outcome of a process of ratiocination or feeling, in which the dynamics are not correlated to the forms of the sensations embraced under those two terms. The fact of anything being done for reasons indicates that it takes its direction from other than dynamic sources. The question of the decision is quite different from that of acquiring motives 0 action. This is a more complex process, for motives are reached by very various routes. But even in attaining motives there can be = equivalency between the energy expended and the mental result, Of course it may be said that there is no separate act involved in a decision of will. It may be correctly said that the determination is simply due to the predominating pressure of the most important and weighty motives. Let this be accepted as true. It is conscious- ness, past or present, which knows which are the weighty motives. Like the prism which bends the course of the rays of light, what- - ever passes through the psychical connection between incoming an outgoing stimulus is determined in accordance with what it finds there, and it is consciousness and its residua which is responsible for the bending. The physiological labor is performed in acquiring the motives which, when acquired, perform acts of will which | at incommensurate with energy, both with regard to their own SS qualities and with regard to the objects towards which they act. is this property of mind which enables it to direct the movements of matter without violation of the law of the conservation of energy. This fact is of the utmost importance to philosophy and to ya conceptions of the universe and of the place of consciousness In 1% These decisions, which we term will, are common to all one beings, from the bottom of the scale up.

Wortman, of the United States Army Medical Museum, has just returned from Arizona, where he has spent the List, and he confirms the importance as well as the genuineness of the discoveries of Mr. Cushing. The expedition is thoroughly equipped and well organized, and its investigations have been con- ducted in a vigorous and scientific manner, with special reference to the many details which go to make collections of this character of value to the scientific student. Not only have the ruins been carefully surveyed and mapped, but each specimen has been labelled with great care, in such a manner as to indicate exactly where found, together with all such other facts in connection with it as will be of use to the student. The expedition has for its object the study of the ancient civili- zation of the southwest, and if the results of the first year’s work ean be taken as an index of what it will accomplish, we may confi- dently look for a solution of this perplexing question. Already a large and valuable collection illustrative of the culture of these prehistoric people has been secured, and it is a matter of congratu- lation that it has been so collected that the scientific student can get all out of it that it can be made to tell. : Mr. Cushing’s ethnological training has been in such a direction as to give him a peculiar fitness for the position which he occupies, having spent six years or more in studying the social institutions, customs, habits, religion and language of the modern Pueblo Indi- ans, and this thorough knowledge of these is indispensable to the proper interpretation of the facts gathered by the expedition. The anthropological work is in charge of Dr. Herman Ten Kate, a native of Holland, son of the distinguished artist of that name. Dr. J. L. Wortman, the Anatomist of the Army Medical Museum of ' Washington, is his assistant. Mr. Adolph Bandelier, whose know- ledge of the early Spanish and Mexican records is well known, 1S connected with the expedition as historian. Mr. Chas. A. Garlick is the civil engineer and topographer. Mr. Fred. Hodge is the draftsman and secretary, while Mr. Yates is the photographer. Mrs. Cushing and her sister, Miss Margaret Magill, are also mem- bers of the party, and have rendered important aid in the classifi- cation and care of the specimens. Miss Magill’s artistic talents have been of special service to the expedition by reason of her clever sketches and drawings of the specimens in situ. . The locality in which explorations have so far been conducted comprises the Gila and Salt River Valleys, situated for the most part. in southwestern Arizona. They are fertile tracts of larg extent, and there can be little doubt that they were once E by a thrifty and prosperous people, whose history remains unwri” ten. The Rio Salado (Salt River) is the principal tributary of te e PLATE X. Spurious Arrow Heads, made from genuine bones.

The land for the most part is covered with cactus, sage brush, grease wood, and mesquite trees, but when cleared and brought under irrigation is made to produce abundantly almost any and all the crops of civilized hus- bandry. Fruits and cereals grow in profusion, and the land is said to be well adapted to the growth of cotton and tobacco. The land rises from the river at a gentle slope, a fact which is of great import- 558 General Notes. While no accurate computations have been attempted, it is sup- > posed, taking into consideration the number of towns or cities known to have existed in the Gila and Salt River valleys, that the population could not have been less than two hundred thousand. There is every reason to believe that these places were not succes- sively, but simultaneously occupied, especially when we remember that they constructed large irrigating canals for a distance of fifteen or twenty miles, which with their rude implements must have been a gigantic undertaking. Their irrigating system was extensive and complete, and covered almost, if not quite, all the cultivable parts of the two valleys. The present inhabitants of the soil have taken advantage of these ancient waterways, constructed at such expendi- ture of prehistoric labor, and they now run many of their irrigat- ing canals in these ditches. These ancient canals were constructed with care. A cross section exhibits a series of terraces widening towards the top, so that a large or small quantity of water could be accommodated and a good depth secured. After the canals were dug they were puddled and then burnt, probably by filling them with brush and then setting it on fire, so that they almost equall terra cotta in durability. Mr. Cushing is of opinion that "d were not used for irrigation alone, but for navigation as wel. There are indications that they used rafts made of reeds (balsas) for navigating these canals, and this appears more probable from the heavy materials that have been brought from a distance. It seems certain that they floated the pine timber used in their building operations down the Salt and Gila Rivers from the dis- tant mountains; it is too much to suppose that they carried this material upon their backs for a distance of a hundred miles. _ urial customs of these people were peculiar and cons of two methods, viz., cremation and interment. In the case of the priestly class the body was wrapped deposited beneath the floor of the house. Generally the bodies were laid along the east wall of the building, with head to the east, although this custom was not invariable. Whe this clan died, a grave was dug in the floor, a foot and a half or two feet deep, and the body placed therein; it was then covere with adobe mud and packed firmly around the corpse. When this covering dried, and the soft parts and wrappings disappeared, the skeleton would be found enclosed in a rude sort of sarcophagus. In numerous instances, two, and more rarely three, skeletons we found in one grave. In all such cases of double or triple bu i the skeletons indicate that it was male and female, or one male pi two females. Buried with each cadaver was a food vessel water jar, and sometimes several of each, often highly decor: dent That they were wrapped in cloths, presumably of cotton, 18 eal from the impressions of the cloth made upon the soft adobe pene Fragments of this material were found and preserved, ing. withstanding its decomposed condition.

The deposited in the grave. This individual Mr. Cushing identified from his paraphernalia as belonging in all probability to the priest- hood of some war order, and this seems more probable when we come to examine the skeleton, for he had sustained a fracture of the arm, and one knee was stiff from anchylosis, no doubt the scars of hard-fought battles, Of the priestly burials something like four or five hundred were unearthed in the various towns, while many more of the cremated remains were found in the vicinity of the pyral mounds. The skeletons, as a rule, were so frail that comparatively few could be preserved. Of the whole number about one hundred good skulls, and probably fifty tolerably complete skeletons, were collected. These were so frail that Dr. Wortman was compelled to use a goodly supply of shellac varnish to keep them from falling to dust. Silicate of soda was tried, but it was not found so good as the ordi- nary shellac dissolved in alcohol. The objects which go to make up the collection are various, and consist of those of ornament and utility. - Numerous shell carv- ings, some of which had been beautifully inlaid with torquoise, were found, while a very few copper ornaments in the shape of bells and earrings were also dug up. Their tools consist almost nary pattern, and are generally well polished ; they are of various Sizes and shapes, and some of them were no doubt used as picks were also found in abundance. The collection of pottery is large, and, according to Mr. Cush- 560 : Gate! Notes. That they were acquainted with metals there can be but little doubt, although they do not appear to have made use of it except in the way of ornament. Some places in the neighboring moun- tains seem to indicate that they mined for ore, which they smelted in crude ovens. Whether this was copper or the precious metals is now difficult to determine, but that they were accustomed to bring these ovens or furnaces to a very high heat is indicated by the slag in their immediate vicinity. It is perhaps premature to attempt to decide who these people were, to whom they were related, and what became of them, I think it fairly settled by these discoveries that they were the ancestors of the modern Pueblos. Whether or not they were in any way connected with the ancient people of Mexico and Yucatan the future alone can decide, It seems certain, however, that one part of them went north to found the later Pueblo civilizations which are now represented by the Zuñis of to-day. If historical evidence is worth anything and if we can trust the ordinary evidences of archeology, then these ruins are beyond ae pre-Columbian, and may be as much as a thousand years l old. Mr. Cushing’s final report will be awaited with interest by all who are in any way interested in the subject. The archæological specimens have been shipped to Salem, and the skeletons will go to the Army Medical Museum in Washington. ; Tue Inprans or British COLUMBIA ! are made the subject of a short article by Dr. Franz Boas, who had the opportunity of studying during three months of the year 1886 several southern tribes of this connection. During that short lapse of time Boas has largely increased our knowledge of their tribes, tribal names, synonymy, and habitat, and has also gathered so much of their dialects as to enable us to divide them into linguistic families. The seven pages of Boas’s article (pp. 422-428) presently before us are chiefly filled with mythologic information, which for that special country is almost wholly new to us. Boas believes that the originated with tribes of Selish lineage (and many of the other North American Indians, he might have added).

From the same author! we have received a few other publications, which refer to the sights seen and facts gathered by himself among the distant tribes visited by him. a between Vancouver Island and the main land. The number of the Indians at present living in British Columbia is put down by Boas at 38,500 (p. 635). “A Year among the Eskimo” in Bulletin of American Geographical Society, New York, 1887, pp. 383-402, impart to us some ideas how the Eskimos of the shores of Baffin’s Bay make their living during the trying winter season of these high latitudes, and also adds myths and songs of this strange people, especially the Sedna legend. This same legend of the Central Eskimos, together with other stories and traditions, are more especially dwelt upon in “The Eskimo” in Transactions of the Royal Society of Canada, 1887, pp. 35-39. Curiously enough, the thunder is a prominent feature in the mytho- logy of these frosty climates (p. 37). Mythologic traits of all the Northwestern tribes are discussed in some German articles of Boas in the Globus of Braunschweig, 1888 ; the first of these legends is contained in No. 8, pp. 121-127 ; the second in No. 10, pp. 153-157. The Sedna legend, together with a considerable number of other mythic tales, legends and stories of these parts, is reproduced in as’ article: “ Die religiösen Vorstellungen and einige Gebrinche der zentralen Eskimos,” (Petermann’s Mitteil. 1887, pp., 302-316.)

This belief makes these Indians very accessible to a future conversion to Chris- tianism; but the Catholic missionaries were not successful with them up to this day, because they neglected to use the main impulse for civilizing savages: to make them work and earn money. Tae MorTILONES! are an Indian nation scattered in numerous bands or tribes through the Eastern Columbian and the Western Venezuelan States, many living south of the Lake of Maracaibo. The Motilones living in the forests and swamps between Zulia and Cesar Rivers, on the border line between the two confederacies, have been very dangerous neighbors to the white settlements ever since the conquest. The name is equivalent to “ pelon,” baldheaded, and also applies to a denomination of monks, who tonsured their hair so as to appear almost baldheaded. It is, therefore, not a name belonging necessarily to one tribe or race only, and indeed we find it repeated in several parts of South America. From 1779 to 1792 the Spanish domination established ten missions among the Moti- lones on the Zulia, of which even the last trace has disappeared in our days. Dr. A. Ernst, Director of the Ethnologic Museum in Caracas, Venezuela, and one of the few men of education who are active in the furtherance of South American anthropology, obtained from General B. T. Velasco the skull of a Motilone man, about forty-five years old, for measurement. He found it to be chameeprosopic a but a little hypsicpehalic, the index for length and width being 9.9. He describes the skull, adding to his accurate measurements all what is known about the tribe of the Motilones. i At the same session a report by A. Ernst was read concerning the language of the Tucurá Indians in the Columbian States. Tucurá is a settlement upon the Upper Sinu, at the mouth of Rio Verde, and these Indians form a population of about seventy. , The vocabulary obtained from the traveller, F. A. A. Simons, 1s printed in the Verhandlungen, p. 302, and contains some Carib terms, many of the terms being oxytonized. wo weeks later, another communication from Dr. A.

It is then transferred to a bath of hard paraffin, or such as melts at 55°C., and is kept there until saturation is complete. I have tried this method with specimens of injected spleen, and find it to work admirably. The sections can be cut with a dry knife. The sections form a ribbon more easily than in the case of ordinary paraffin imbedding. The sections may be freed from paraffin with chloroform before mounting if they are required for histological purposes, as they may be handled with the greatest ease on account of the presence of the celloidin which holds them together. They can then be stain in hematoxylin (Kleinenberg’s) or in nigrosin, or double staining effects may be produced by the use of other dyes in combination with hematoxylin. i ~ To many persons the oil of origanum has a disagreeable odor, and is almost as inflammable as turpentine ; besides, it darkens or oxidizes in a short time, and has, I think, a tendency to shrink the object slightly, even after treatment with celloidin, and also to arken it. These disadvantages I have lately avoided by substituting chlo- roform for the oil of origanum, used by Dr. Kultschizky. I pro- ceed in the same manner as he recommends with the imbed E rocess as regards the first, second, and third steps. The fou step is to place the object soaked with celloidin in the usual way in chloroform until saturated, instead of in oil of origanum. 4t 18 then transferred to a mixture of paraffin and chloroform, ual parts, kept at a temperature of 40°C., and finally, until comp ete saturation is effected, in molten hard paraffin melting at 55°C. od o clean the sections for mounting, they may be mount 5 directly from the chloroform, if the operator is quick enough ant does not let the chloroform evaporate from the section before it 18 covered with balsam.

XXII. JULY, 1888. No. 259 MEGALITHIC MONUMENTS OF BRITTANY. BY THOMAS WILSON. _ pe term megalithic has been recognized in France as applying to the unhewn stone monuments erected by man in prehistoric The ancient province of Brittany consisted of the area comprising the present five departments in the northwest corner of France: Finistère, Côtes du Nord, Ille et Vilaine, Morbihan, and Loire Inférièure. This province is exceedingly rich in megalithic monu- ments—in some respects it is the richest in the world. The man of the paleolithic period does not seem to have occupied this part of France. In only two places have any of his imple- ments or utensils been found, and these are on the extreme eastern edge of the province. However, that is of little moment in the Present discussion, for the prehistoric man of that age having made no Monuments, left none. 1€ occupation of Brittany by prehistoric man began in the Neolithic age or age of polished stone called by M. de Mortillet Rebenhausen, after the station of that name in Lake Pfaffikon, near oe Switzerland. This was in the present geologic epoch and e man 18 supposed to be of our day.

He had 574 Megalithie Monuments of Brittany. not the art of the former epoch, enabling him to represent by engraving or sculpture the living things he must have seen; his art was confined to the ornamentation of his dress and the decoration by lines and dots in geometric patterns of the pottery, and after- wards the bronze, objects which he used. He was capable of long-continued plodding labor and performed herculean tasks in the construction and erection of his monuments. He had a religion: he buried his dead, depositing some of his choicest valuables in the grave with them and erecting over them monuments of the grandest and most expensive character ; these have endured until the present time, and are now being bought, restored, and preserved by the state. The names given to megalithic monuments as adopted in France are taken principally from the Breton language. Men means a large stone. Hir means on end. Menhir means a large stone standing on end. Dol means table. Dolmen means a table of stone. Lech means a smaller stone. Cromlech means a circle of stone. It also has a higher signifi- cation, that of eternity, such as is symbolized by our circlet of gold, or the snake in that form, swallowing its tail. Alignment and tumulus are modern French words, and mean, the first, lines of menhirs; the second, a mound of earth or stones usually covering a dolmen. The megalithic monuments of France are under the supervision of a governmental commission appointed by the minister of fine arts; of this commission Henri Martin, the historian, was, until his death, and Gabriel de Mortillet now is, the chief. he commission has authority to purchase, subject to approval, such monuments as it may deem worthy of conservation, and when purchased, they may be restored to their original condition and properly preserved. A certain sum of money is appropriated for the use of this commission, The members serve practically with- out compensation. The action of the French Government 1n this regard is in the highest degree commendable. The Anthropo- logists’ Society of the United States might well urge upon the Gov- ` Megalithic Monuments of Brittany. 575 ernment the adoption of similar measures for the protection of American Indian mounds and other ancient monuments against the destruction with which they are threatened. The French commission has published a list of the megalithic monuments of France. The total number was put down at about 6,300; of these 1,600 (increased by later discoveries to nearly 2,000), are in Brittany. They are thus classified and distributed : | d ‘ Z g n £ S a > n = Province. È a € 2 2 20 F = = Bea Å S gi S S S fz!

Its floor and entrance were at about the level of the neighboring surface, and the entire monument is believed to have been covered with earth; thus in ancient times it was a tumulus. The menhir is a single stone planted on the earth and standing erect. The cromlech is a greater or less number of menhirs arranged in form of a circle or a square. The alignment is the same as the cromlech; only the menhirs are arranged in nearly parallel lines. All of these monuments consist of large unhewn granite stones. The smallest of the stones used we estimated to weigh a ton. Some, indeed many, have been accurately calculated upon the known basis of 2,700 grams for one decimetre cube, or say two tons avoirdupois for a cubic yard. ; The covering stones of a dolmen have been found to weigh five, ten, twenty, and forty tons. The alignment menhirs weigh from Fre. 1.—Dolmen of Crucuno, thirty to sixty tons: two near Plouharnel weigh respectively eighty- be and the three and ninety-six tons, the former that of Sainte Bar latter that of Erdeven. Megalithic Monuments of Brittany. 577 DOLMENS. There are in the department of Moribihan about 400 dolmens, some in ruins, but many well preserved. Used for sepulture they may be described as houses for the dead. They are perhaps the earliest form of receptacle for the dead, although the Kistvaen, made of smaller flat stones with sides, ends, top and bottom shaped like a box or chest (Kist) and covered with stones like a cairn, may be older, but they may also have only been the sepultures of a poorer people, he dolmen of Crucuno is most frequently shown to the visitor. It is easy of access, is on the road from Plouharnel Carnac to Erdeven. It is large, in good condition and presents a fine appear- ance. It was used as a stable before being purchased by the government. Its form, size, and condition make it a good repre- sentative dolmen. Fic. 2,—Dolmen of Lochmariaker. The dolmen of Lochmariaker is situated near the village of that name overlooking the Gulf of Morbihan at its opening into the z Lochmariaker has many evidences of Roman occupation. It on this gulf, and probably within sight of this spot, where Was 578 Megalithic Monuments of Brittany. took place the great sea fight between Cæsar and the Venites. It has but a single covering stone bearing the form and worn appear- ance of a huge boulder. I do not know its exact size, but as I remember it it is twenty to twenty-five feet in length, nine or ten feet in breadth, and two or two and one-half feet thick. The chamber is rectangular, somewhat smaller than the dimensions of the covering stone above given, and is six or seven feet in depth. The bottom of the covering stone, plainly to be seen from the interior by looking upwards, is decorated with the representation of an immense polished stone hatchet or celt, with a long handle terminating in a knob. The instrument is represented in outline by a groove which has been cut, or rather pecked, into the granite surface. Fic. 3.—Dolmen of Grand Island. Another form.

It is believed that the interments were made continuously in the same sepulture (as is done partially in our own vaults), a practice which prevails to a certain extent in the country to the present day. When the dolmen (or tomb) became full, the skeletons could have been taken out and deposited in an ossuary. We found evidence of this at the dolmen of Port Blanc. It has been contended with great probability that the bodies were buried elsewhere at first and then after they had become dessicated or the flesh had been removed from the skeletons, that the bones were placed within the dolmen. M. Cartailhac has elaborated this theory with much ability. A fete day, like All Saint’s, was perhaps selected for the purpose, and the dolmen may have been opened and all bones deposited therein with due ceremony. In support of this view it is argued that the skeletons have been found in unnatural and impossible positions in the dolmens; that they have been found colored or painted, which could only have been done after the denudation of the flesh, and that sometimes the entrance to the dolmen is by means of a hole cut in the stone door, so small, from sixteen to twenty inches round or oval, that the entry of a corpse would be difficult, if not impossible. Fre. 6.—Cireular hole being the entrance to a dolmen, from the department Sune-et-Oise, now removed to and exhibited at the Musee St. Germain, Paris, The round cover being in the foreground, Excavations and searches were conducted by myself in company with the local archeologists, M M. Gaillard, Fornier, Cappe, Rialan and the Abbe Luco. I subjoin a list of some of the larger stones in the more important dolmens, with sizes and weights. 582 Megalithic Monuments of Brittany. Dolmen of Crucuno: Property of the government; the covering stones seventeen feet long, ten and a half feet wide, 30.3 inches thick; weight forty-one tons of 2240 pounds (Fig. 1.) Second dolmen of Rondessec: Property of the government; has two covering stones both about the same size and weight, 11.6 feet long, seven feet wide, twenty-eight inches thick; has eighty square feet of surface, 198 cubic feet, and weighs fourteen and one- half tons. First dolmen of Mane Kerioned: Property of the government ;. has thirteen supporting and four covering stones, one of which weighs about ten tons. Its chamber and gallery are twenty-eight feet long. Second dolmen of Mane Kerioned: Has twenty-four support- ing and four covering stones, one of which weighs seventeen tons. Its chamber and gallery are thirty-four feet in length. This dolmen has extensive sculpturing on the supporting stones forming the sides and ends. Dolmen of Mane Groch: Property of the government; has a corridor, large central chamber and three side chambers, it has - twenty-three supports and seven covering stones. Dolmen of La Madeline: Has five supports and two table or covering stones. First dolmen of Mane Bras: Has thirteen supports and two table or covering stones, and weighs ten tons. Second dolmen of Mane Bras: Has nineteen supports and two tables, and weighs ten tons, Dolmen of Kergaval: Has six supports and one table and weighs twenty tons. ; It was once the fashion to speak of these monuments as having belonged to the Druids. This seems to be a tradition that has grown up within historic times and long after the Druids had passed away. The dolmens belonged as well to the age of bronze as to that of polished stone. Incineration and inhumation were both customary, but the former method pertains more to the bronze ST ifal There are about 3,500 dolmens in France.

Many of the dolmens are now covered with earth, and these have been called tumuli. It is believed by those best qualified to judge, after the longest experience and closest examination, that all have at one time been so covered. One reason for this belief is, that it is universal to find the gallery, corridor or covered way, made of the same kind of stones in the same way, on the same level nd leading from the principal chamber, gradually narrowing in =< ~ SS FIG. 4.—Section of a pasne In. the dolmen with its corridor or alley-waY and means of second interm both width and height to what would appear to have been the circumference of the tumulus.

In this way, the tomb could be covered, the monument completed and yet 584 Megalithic Monuments of Brittany. the entrance be easily opened and entered upon the occasion of a second or subsequent interment. The covering of these tumuli consists of layers of broken granite alternated with layers of clay and mud from the seashore and vegetable earth from the neighboring surface, The tumulus of Gav’r Inis has a dolmen remarkable for the sculpturings. It is eight feet by seven, five feet eight inches high, with a corridor or alley fourteen feet long, four feet six inches wide ; five feet four inches high, while the tumulus crowning it is 180 feet in diameter and was thirty feet high.

MENHIRS, The dimensions of some of the menhirs is as follows : Penmarch, twenty-five feet high; Cadiou, twenty-eight; Mount .

The menhir stands single and alone. When arranged in parallel lines as they sometimes are, they are called alignments, ALIGNMENTS. The Province of Brittany has twenty-three alignments—one-half of those in all France. The department of Morbihan and Finis- tère have, together, seventeen of these. Carnac has in its imme- diate neighborhood six out of these seventeen. These six align- ments represent 3,000 menhirs. : Menec, near Carnac, has 835 menhirs, arranged in eleven parallel lines, 3,778 feet in length and 328 feet in breadth at the head, 586 Megalithic Monuments of Brittany. tapering to 200 feet at the tail. It has at its head a cromlech of sixty-two menhirs. Kermario has 678 menhirs, no cromlech, nine parallel lines, 4,037 feet in length—same width as Menec. Kerlescant has 258 menhirs, a cromlech square of thirty-nine menhirs, thirteen lines, 1,000 feet in length—393 feet width at the head and 164 at the tail. Erdeven has thirteen lines, 1,120 menhirs, 6,886 feet in length, 836 in width at the head and 180 at the tail. Fia. 10.—Alignment of Menec., About one-half of these have been overthrown and are lying On the ground. About ten per cent. should be added for all the menhirs known to have been destroyed in modern or historic times. Without doubt the gaps now existing were once filled. This would double, at least, the number. These monuments have served as stone quarries for the neighborhood, and doubtless the great castles and churches of the early ages were built therefrom. The light house at Belle Isle was built of the granite menhirs of the align- ment of Erdeven. Thus they stand, dotting the country in every direction, enormous, Megalithic Monuments of Brittany. 587 rough, rude, unhewn granite stones—great in their mightiness, mysterious in their solitude, belonging to another civilization mighty in its time, but now dead and buried in the ages of the past. They have no inscriptions, and no history. We know them to have been the work of man, and that is about all. In the case of menhirs, they rear their heads like great giants. In the align- ments they stand in close array with serried parallel lines, and stretch across the level country miles away, their bodies gnawed and their heads scarred and seamed by the tooth of time since the distant ages when they were erected. It is their size, their sim- plicity, their number, their repetition, as well as their antiquity, which render them so imposing and so impressive. No words can convey to our mind an adequate idea of this impressiveness. They must be seen to be appreciated. A word as to the age of these alignments. The menhirs, whether standing or fallen, are frequently used as fences, the interstices being filled usually with an earthern embank- ment. In the headline, at the alignment of Erdeven, many had fallen and were thus covered with earth. On uncovering them, one four or five fect thick and ten or twelve feet long was found, hewn as it lay, for what purpose we knew not, but we could see the marks of the tool. It had served as a fire-place. There were the charcoal and stone bed and back wall, all bearing traces of fire. Pieces of flint, a small celt of fibriolite, débris of pottery, (some dolmen, but much Romar§, showed that this occupation belonged to the Roman times ; that is, somewhere between’ 40 B. C. and 405 A. D. -This menhir had been prostrate from fifteen hundred to nineteen hundred years; yet it had previously stood on end long enough time for the top to become so weathered as to be plainly distinguishable from the bottom. There is on the menhirs quarry no mark of tool or of quarrying, yet I think they were quarried. They are so much weathered that all marks are worn away. Look atthe weathering on the top of the menhir of Penmarch (Fig. 6). No traces of a quarry have been discovered, though the granite of which the menhirs are formed 18 the local rock, coming always near and many times quite to the surface. The menhirs have evidently been planted. In most cases they stood on the surface without any foundation, but founda- tions had been built where needed. In many cases the smaller end of the stone was downwards. ee 588 Megalithic Monuments of Brittany. Flint implements and chips and broken pottery are found about and among the alignments as elsewhere over the country, especially around the foot of the menhirs, showing a prehistoric occupation ; but no trace of the uses or purposes of the menhirs or alignments have ever been discovered. There have been many theories broached but no facts adduced sufficient to support them. They may have been called military camps or religious or other rendezvous for the people. They may have been tents. No trace has been found of their use as burial places, and so far as established by ascertained fact, the popular idea is as near the truth as any other, viz., that they were the columns of a sacreligious invading army, turned to stone by the wrath of an offended God. SCULPTURINGS. Many of these stones or monuments have marks or sculpturings on them. The menhirs of the alignments have cup markings only, and these are rare. In some cases they have been marked in with crosses, modern times, made sometimes by religious devotees, sometimes by the priests, done in order to prevent or break up any chance remaining pagan custom of worshipping, or revering, or employing these stones. The dolmens are marked with various signs, none of which have any discovered signification. They have received much attention and study, but without result. The sculptured monuments of Brittany are all near the sea-coast. Yet there is no rule and no unfformity. Many of them near the coast are without sculptures ; and this is true of an entire section or neighborhood ; again other dolmens in the interior will be sculp- tured. Do these different sculpturings represent the dwelling places of different tribes ? CON CLUSION, The story of these monuments has never been aai told. Their condition and position may be described, and that of the skeletons and articles or implements found. It is from these details that the history is to be obtained, of the prehistoric man who made them. They must be studied with intelligence and care. Comparisons must be made with other articles found in the same place and with the same articles in other places.

HOLST’S STUDIES IN GLACIAL GEOLOGY. RY DR. JOSHUA LINDAHL, WE have before us two pamphlets by the Swedish geologist, Dr. Holst, of Stockholm. One of them bears the title, “Om de glaciala rullstensiisarne ” (“On the Glacial Gravel-Osar ”1); the other, “ Berättelse om en i geologiskt syfte företagen resa till Grön- land ” (“ Report on a Voyage to Greenland for Geological Investi- gations” 3). The subject of these papers has so much bearing on the geology of our own country, and is so ably treated by their author, that we have thought it desirable to present the following condensed translation of them. In the first-mentioned paper Dr. Holst propounds his new theory of the origin of glacial osar. The history of the development of this theory is, briefly, the fol- lowing : Hisinger (in some cases), Martins, Chambers, A. Erdman, Torell, and others, explained the said formation as ancient sea- Shores. Hisinger (in other cases), v. Helmersen, Térnebohm, Levin, Jernström, and others, assumed that a vast deposit of sand — and mud covering- the country had been cut through by rivers, whose beds were gradually filled with stones and gravel.

Pages 1-68. ; 590 Holsts Studies in Glacial Geology. the sand and mud was washed away, leaving the stone and gravel deposits of the rivers in the shape of ridges. Hummel was the first one to recognize the fact that the existence of an inland ice must be pre-supposed as the indispensable agent in forming such ridges; ` but he regarded them as formed beneath the ice in tunnels exca- vated by percolating waters. Finally, in 1876, Holst published his new theory, which in 1878 was also used by Warren Upham in his report of the geology of New Hampshire. Dr. Holst’s theory stands now without a rival. The following short extract of Dr. Holst’s paper may be sufficient to explain his views. He says :— “ For a correct interpretation of the origin of gravel-osar it is of main importance to answer the question how it was possible for running water to deposit its silt in such shape as that of an ordinary gravel-ose.” There can be no further dispute that these deposits are old river-beds. How, then, have they happened to assume the form of elevated ridges, rising above the adjacent country? ” The water at the surface of the melting glacier gathers in the val- leys of the ice-sheet, whence it extends its coastward course in rivers whose beds are cut down in the ice-sheet. The ice along these rivers _ melts faster than that farther off, and in melting it gradually releases its contents of moraine matter. This matter will then follow the water, although at a far slower rate, down to the said valleys, and is ‘finally—at least partially—swept along into the rivers, where the gravel-grains will be worn and their angles will be more or less rounded off, according to the swiftness of the current. This same factor will also regulate the assorting of the material and determine the place where each individual boulder, pebble, or grain shall be dropped. Layer upon layer will thus accumulate in the river- bed, and, when finally the entire glacier has melted away, the accu- mulated silt of the former river-bed will present itself as a ridge elevated above the surrounding ground ; it is an ose. “Tosumup: ` “ Osar are formed in running water. “ No running water could lift all this matter to the considerable altitudes where we often find it. 1 Geol. of N. H.

He went as far north as Sukkertoppen (lat. 654° N., about), extending his rambles southward to Kipissako, southeast from Ivigtut! (lat. 61° N., about). He traveled mostly by water, in a so-called Umiak (boat rowed by women), but also made excursions by foot over the inland ice, ascend- ing some of the highest mountain-peaks for the purpose of obtain- ing bird’s-eye views over the ice and the various pinnacles—s, ec. nunataks—which rise out of the inland ice. After having given a general account of his travels, the author proceeds to discuss his observations under the following headings, viz.: the ground-rock, the inland ice, the kryokonite, the moraines, the upper drift deposits, the glacial clay, and the peat. We shall here reproduce the most important parts under the first five of these headings, A. The Ground-rock in the district referred to is predominantly grey gneiss. A bed of héilleflint-gneiss was observed on the penin- sula to the north of Tigssaluk. More variation was noticeable east and south of Ivigtut. A rather coarse-grained, well-developed syenite extends over the country a little to the east of Grénne Dal; a white, pretty quartzite, and also what may be called a hédilleflint- _8chist, were seen near the southern ice-blink at Kornok, and a some- what similar but very fine-grained schistose hdlleflint-gneiss occurs at Kipissako, _ No granite was seen north of Ivigtut ; but a limited area of granitic rock extends to the north of Kipissako glacier. In order to get some more definite knowledge of what rocks pre- vail in one locality, the author collected at random fifty specimens from the terminal moraine below the Ursuk-f jord glacier. Of these 50 specimens, 12 were found to be diorite; 9 grey gneiss; 7 granite (or granite-gneiss), some grey, some red ; 6 grey hiilleflinta ; k Dr. Holst mentions, as a warning to other scientists who may go to ik pre with the intention of visiting the cryolite mines at Ivigtut, ission to those mines is absolutely prohibited to all strangers not presenting a written permit from the head office at Copenhagen, He might have added, that such a permit is never granted. 592 Holsts Studies in Glacial Geology. 4 hiilleflint-schist; 3 red granite, of more than medium-coarse grain; 2 grey granite—otherwise like the last-named variety; 1 red hälleflint gneiss; 1 quartzite and 1 quartzite-sandstone ; whilst the remaining 4 specimens were put down as undeterminable. In the same moraine were also noticed limestone, red fine-grained sandstone, coarser sandstone, and sandstone conglomerate, sometimes with nodules of jasper and diabas. The sandstones and quartzites are very compact, as is generally the case with older sandstones, and bear a complete resemblance to many Swedish sandstones generally regarded as Cambrian. C. Pingel (in 1843) expressed his opinion that they are Permian; and K. J. V. Steenstrup (in 1877) takes Pingel’s side, and (in 1881) declares that there can be no reason for a different view as long as no petrifactions have been found in the sandstone. Yet there is no more reason to regard this rock as belonging to the Permian formation than to almost any other for- mation. Numerous dykes of diabase are met with in the southern portions of the district visited by Dr. Holst, all the way from Kipis- sako to Fredrikshaab. They are particularly abundant on the Tassiussak-fjord, and not less than twenty parallel dykes of green- stone were counted within a space of five hundred feet on the island Kikertarssuak, at the inlet to this fjord. East-southeast from Grönne Dal occurs a peculiar diabase breccia, and, close to it, dykes about a yard wide of a very fine-grained red rock, microscopically determined by Dr. A. E. Térnebohm! as a fine-grained syenite. B. The Interior Ice-covering.— Previous explorers of the inland ice have made the observation that moraines are found on the sur- face of the ice only near land, while the inner expanse of the ice- sheet is earthless, except the occurrence of the so-called kryokonite. What else it carries along is hidden more or less deeply in the mass of the ice. Knowing this, Dr. Holst thought it more fruitful to study the ice near its borders than to undertake time-wasting excur- sions into the interior. The inland ice expands ina continuous sheet from the mountains of the coast-lying land eastward beyond the horizon, only interrupted by the “nunataks” and the moraines. The former occur v sparingly, only the high peaks of the underlying mountains rising 1 A. E. Törnebohm: Mikroskopisk undersökning af nägra b prof frän Grönland insamlade af Dr. N. O. Holst. Geol. Fören. Förb. Bd. 6, p. 692. Holsts Studies in Glacial Geology. 593 above the ice. Of the moraines may be especially mentioņed the morain-osar, deposited on the ice parallel to its border, and in undu- lating or even horseshoe-curved lines, following at some distance the headlands jutting into the ice-sheet. These moraines Dr. Holst proposes to call border-moraines (‘ rand-moriiner ”). The ice within a hundred feet from its borders invariably presents a slope toward the border, though generally not so steep as to ren- der the ascent at all difficult. Farther in the slope is much less marked, though there appears to exist a general rising toward the east, whilst the surface everywhere presents vast undulations. The border of the ice appeared to have retreated quite recently in many places; in others it had evidently advanced. This seems to be the necessary effect of the varying amount of precipitation of snow or rain over the glacier-basin, causing the glacier itself to vary in volume. The snow fallen during the winter seems to remain much longer on the inland ice than on the land. Thus, at Atarngup, above the Tassiussak-f jord, on the 25th of June the inland ice was covered with snow. At the Fredrikshaab glacier, on the 4th of July, the snow had melted near land and around the “ nunataks,” but remained over a great part of the ice-sheet, although numerous bare spots were visible. Still later in the season—by the middle of September—Dr. Holst made an excursion over the inland ice to the north of the Kipissako glacier. All the snow from the last winter had disappeared, but some new snow, blended with rain, had fallen and frozen to a thin crust over the ice. On the surface the inland ice either presented the appearance of a compact mass of coarse crystallinic texture, reminding of the grain of common rock-candy, or else it is honeycombed by the solar heat and shows intersecting systems of parallel plates, apparently the remnants of large ice-crystals, often several inches long, which have wasted away, only leaving the frame, as it were, on which they were built. These plates or tablets are highly mirroring, reflecting the Solar rays in all directions, depending on the position of each indi- vidual crystal. The ice in the wild, mountainous regions of Southern Greenland is, as a matter of course, very much broken up by crevasses, Wherever the ice pushes forward and downward over an escarpment of the underlying ledge these crevasses, with great regularity, cross the direction or course of the glacier. Of most frequent occurrence, however, are the cracks which run at right Angles to the borders of the inland ice. 594 Holsts Studies in Glacial Geology. Although the ice in the said mountainous district is everywhere crevasse-torn, it is not necessarily so in other localities. Where the underlying ground is level or only gently rolling, the moving ice is, no doubt, entirely free from cracks. The local direction of motion must, of course, to a great extent conform to topographical conditions, Thus, in deep valleys glacial striæ may be found to run in all possible directions, always follow- ing the course of the valley. In order to find the general direction of the motion of the inland ice, one must study the striz on the high plateaus. My observations in such localities indicate a direction from northeast or east-northeast. The vastly broken aspect of a Greenland landscape cannot be explained as solely a product of the erosive force of moving glaciers. It is true that the material produced by this erosion is only to a small extent left on the land—where the soil is, indeed, very thin— whilst by far the greater part is deposited as silt in the sea. But if we suppose this silt to spread over the bottom of the sea for some miles from the coast and to have the thickness of several rods, still this cannot approximately account for the enormous excavations of the land. These must date farther back than the glacial period. The glaciers may, however, have plowed up and scooped out the loose sediments from earlier ages in the vast valleys. On the inland ice occur moraines and kryokonite (glacial dust), besides patches of vegetable matter. The moraines are limited to the borders of the inland ice around the nunataks as well as along the coast-line. The kryokonite mostly accumulates between the moraines thus near to land, but is not altogether absent even from the high interior tracts of the ice-sheet. Vegetable matter occurs but sparingly on the ice. West of Kangarssuk, half a mile from land, were noticed some leaves of grasses, Betula, ete. They were not scattered, but heaped up in a pile—which seems to indicate that not wind, but water, had transported them to that position. C. The kryokonite is extensively distributed over by far the greatest part of the inland ice, as well as over most of the local glaciers, though it may occasionally be hidden under snow or Ice formed by the freezing of the thaw-water.! It varies, however, 1 — Swedish smältvatten. The word, although not found in Webster, may serve to express the water formed at the surface of the ice by thawing. Holst’s Studies in Glacial Geology. 595 considerably in quantity. In many places, especially far inland, the kryokonite spreads only as a light shade over the ice, whilst near to land it exists in far greater abundance. At Fredrikshaab’s ice-blink the border-ice was dirty from immixture of kryokonite and separated from the higher-located, cleaner ice by a sharply-defined line parallel to the foot of the inland ice, this line having an elevation of six hundred feet over the foot of the ice. The kryokonite has a dirty gray color, and upon superficial inspection appears like clay ; but, on closer examination, it will ound to consist of very fine sand. Quite often it is formed in little balls as big as beans, which readily absorb heat from the sun, caus- ing the underlying ice to melt, so as to produce the so-called “ organ- pits.” It may occasionally be washed down with the thaw-water from the higher places and then accumulate in patches. On the Arsuk glacier some such patches, about one square foot each in extent, were covered with kryokonite to a depth of three inches. It is not always easy to tell the difference between moraine-sand an kryokonite on the ice-rivers, where the moraine matter exists in every grade of fineness—from coarse gravel and sand to nearly im- palpable dust, like the kryokonite. On the higher parts of theinland ice, where no moraines are found, this difference does not exist. The following table shows the chemical composition of the kryo- konite.

In his “ Account of an Expedition to Greenland, 1870,” Norden- skidld gives the above analysis No. 1, and, on the strength of it, pronounces the kryokonite “a trachytic sand of a composition (e. g., the amount of sodium), which indicates that it does not derive its origin from the granite-bearing region of Greenland.” He leaves the question open whether it is derived from the basalt region or from volcanoes supposed to exist in the interior of Greenland, or whether it is of meteoric nature. He regards it as a distinct species, for which he gives the chemical formula, and even states that its crystal form is probably monoclinic. By comparison with the analysis (A) of a Swedish gneiss, it becomes evident that his con- clusions are invalid, Evidently the analyses point to the primitive rocks of Greenland as the origin of the kryokonite. Even the high percentage of soda has no great bearing on this question, as many wedish gneisses! have a higher percentage of soda than the above 0.1, Dr. Holst devoted special attention to the kryokonite in Green- land, and collected samples of it from ten different localities between lat. 61 N. and 65° 25’ N.?; and he came to the conclusion that this substance is nothing but the finest till separated by repeated washing. The thaw-water from the surface of the inland ice penetrates through cracks into confluent gutters down in the moraines in the deeper parts of the ice, and, washing out the finest till, it continues its course until it connects with similar gutters, carrying water from higher-located tracts. Hydrostatic pressure will then force back _ water toward the lower tract. The suspended moraine matter will follow ; but as"soon as equilibrium is restored it will settle in pores and cracks of the ice. The water may but rarely reach the surface immediately. But when the moving glacier encounters an elevation of the ground,*the lower portions of the glacier will be pressed up to a higher level. As the ice is melting away from the surface the enclosed matter will gradually appear at the top. Upon reaching the borders of the inland ice it will be carried away by the glacier- rivers and deposited in the sea. These rivers in Greenland are 1 According tojSantesson’s “Kemiska Bergarts analyser.” Sveriges Geol. Underséknin iit 2 Nordenskiöld’s sarriple were all taken from nearly the same locality, viz., about 68° N. lat. Holst’s Studies in Glacial Geology. 597 very turbulent, and the kryokonite, therefore, mingles with the clays and sands, which are whirled down by them into the sea. But if such inland ice were advancing over a plain, and the kryo- konite were washed out from it by quietly-running water, it would, no doubt, get an independent geological significance. This theory presupposes the existence of kryokonite, not only on the surface of the inland ice, but also in its deeper parts. That this is the actual case is plainly visible near the borders of the ice. Microscopical analyses of the kryokonite were made in 1881 by A. von Lasaule, F. Zirkel, and E. Swedmark. All agree in the main: The kryokonite contains nothing but the ordinary components of primitive rock. Professor Zirkel found Dr. Holst’s samples to contain mainly the, following minerals, viz., quartz, orthoclase, plagioclase, greenish and brownish mica,—which he supposes to be a magnesia mica,—and colorless potassium mica (this last mineral occurring but rarely) He also found some hornblende, garnet, magnetite, and (doubtfully) traces of titanite and epidote. In all cases the principal constituents were quartz, magnesia mica, and feldspar. The thinnest scales of _ Mica pierce through the feldspar fragments, just as they do in the gneisses, Metallic iron was never identified in the samples. Pro- fessor Zirkel calls particular attention to the total absence of any augite, olivin, or glass. Both chemical and microscopical analyses agreeing, it may be regarded as a settled fact that the kryokonite has the same origin as the moraines, It is far more difficult to solve the question regarding the geological significance of the kryokonite. During his visit to Greenland, Dr. Holst was inclined to suppose that it nowhere forms independent deposits, but always occurs commingled with the clays and fine sands of the till, the kryokonite, as to its grain, being intermediate between the two. It is sand, but considerably less palpable than any ordinary kind of sand. How- ever, since he had opportunity of studying the /oess in Saxony, he came to the conclusion that the loess is nothing but kryokonite. _ Considering the loess (kryokonite) as a product of repeated wash- ing processes, in the manner above stated, it is easy to conceive why ìt has reached such remarkable extent and purity. The State Geologist, E. Swedmark, having examined microscopi- cally samples of loess collected at Ebendorff, near Magdeburg, and 598 Description of Meadow Mouse. at Dresden, found them to consist of fine rock-powder, in which he identified fragments of quartz as the most prominent constituent, besides feldspar, plagioclase, green hornblende in considerable quantity, mica (mostly biotite), a trifling amount of magnetite, numerous dendritic or, sometimes, kidney-shaped grains of an ochre- like mineral, and fine particles of clay and limestone. Such a com- position (says he) indicates certainly that this loess leads its origin substantially from disintegrated primitive rocks (gneiss or granite) and diorite. ` The dust on the inland ice of Greenland offers a suitable soil for quite a number of small algæ. Professor V. B. Wittrock examined some of the samples of kryokonite, and the results of his investi- gations are embodied in his paper, “Om snöns och isens flora.” * (To be concluded.) DESCRIPTION OF A NEW PRAIRIE MEADOW MOUSE (ARVICOLA AUSTERUS MINOR) FROM DAKOTA AND MINNESOTA. BY DR. C. HART MERRIAM, LARGE series of meadow mice of the genus Arvicola, col- lected during the past two years in Minnesota and eastern Dakota, comprises but two species, which, in the field notes of the collector, Mr. Vernon Bailey, are designated respectively as “ up- land” and “lowland” meadow mice. The “upland” form is neve? found on the marshes, but the “lowland,” which is most abundant in wet meadow lands and in the neighborhood of streams, some- times occurs on the dry prairies in company with the other. Exter- nally, some of these mice resemble one another so closely that sharp discrimination is necessary for their separation. A glance at their teeth, however, shows that they belong to different sub-genera The “lowland” species has two external closed triangles on its last upper molar, a postero-internal loop or “spur” on its middle upper 1 A. E. Nordenskiöld : Studier och forskningar, föranledda af minas resor i höga norden. Stockholm, 1883, pages 63-124. Description of Meadow Mouse. 599 molar, and three internal and at least two external closed triangles on its front lower molar—and consequently is a Myonomes, closely related to our common eastern meadow mouse, Arvicola (Myonomes) riparius. The “upland” species has but one external closed trian- gle on the back upper molar, lacks the “spur” of the preceding tooth, and has but two internal and one external closed triangles on the front lower molar—in other words is a Pedomys, nearly related to the prairie meadow mouse of the Mississippi Valley, Arvicola (Pedomys) austerus. For purposes of critical comparison, therefore, the remaining sub-genera of Arvicola may be summarily dismissed. The sub-genus Pedomys, according to Coues, the latest monographer of the group, contains but the single species, austerus. He also placed in this sub-genus, and in fact as only sub-specifically separa- ble from austerus, a very different mouse (namely, his Arvicola aus- terus curtatus) which is not, a Pedomys at all, but, as I have recently shown, belongs to the sub-genus Chilotus. This leaves austerus as the only species with which Mr. Bailey’s “upland” mouse may be compared. The principal difference is in size, the new form being \ 2 male Arvicola (Pedom J 2 Í ys) minor Merriam. 1 and 2, skull from about and below + Upper molar series, X5; 4, lower molar series, <5. — that in the case of the mice the ranges of the two are not — to overlap.

The average difference in length, without the tail, is nearly 25 mm. (about an inch). In typical austerus, the hind foot averages 19 to 20 mm., while in the new form it averages but 16 to17 mm. In adult skulls of austerus the average basilar- length falls between 24 and 25 mm.; in the northern form it falls between 20 and 21 mm. In reference to its diminutive size, I have named the northern mouse ARVICOLA AUSTERUS MINOR, sub-sp. nov. Northern Prairie Meadow Mouse. Type 392%, male, Merriam Collection. From Bottineau, Turtle Mt., Dakota, August 27, 1887. Description of Type.—Similar to Arvicola austerus, but much smaller; length from end of nose to tip of tail vertebrae (measured in the flesh), 133 mm.; tail vertebre, 36 mm.; hind foot, 16.5 mm.; ears rather prominent, slightly overtopping the fur. Color.—Upper parts uniform grizzled gray; under parts whit- ish, washed with pale cinnamon. Viewed from behind, looking away from the light, the entire head, back and sides appear to be finely and closely lined with silvery. The fur of the belly is plumbeous basally and nearly white apically. There is no sharp line of demarkation between the color of the sides and that of the belly. Tail bicolor, the light color of the under surface reaching well up on the sides. Description of other Specimens.—The type, which is from Turtle Mt., Dakota, is very closely matched by specimens from several places in the Red River Valley (particularly from Travare, Dakota, and Ortonville, Minnesota); and by a few of the Elk River speci- mens. A male from Elk River (No. 3424), collected June 2, 1886, is almost a duplicate of the type, except that the belly is darker— it is more sparsely haired, and the plumbeous basal portion of the fur shows through. Other specimens from Elk River have the upper parts strongly suffused with brown, and the belly strongly washed with cinnamon. In others there is as much whitish on the belly as in the he while in others still the under parts are of the “muddy rust color so often seen in true austerus. This is pronounced in No. Hit, Surface Fauna of the Bay of Fundy. 601 male, from Elk River. The variations in color of under parts do not seem to depend on age, sex, or season, though of course the fur is everywhere longer and more dense in winter than in summer, as is the case in all northern Arvicole. General Remarks.— Arvicola minor is so different from all Amer- ican Arvicole except austerus that comparison with others is unne- cessary. Lest, however, there should be any question as to its dis- tinctness from “A. cinnamonea” of Baird, which is said to have come from Pembina, I have measured the skull of the type (No, 591, male, U. S. National Museum—the skin has been lost), and find it to be as large as that of austerus proper. And Baird’s mea- surements of the animal show that it was larger even than average austerus. The dental peculiarity pointed out by Baird as one of the distinctive characters of the supposed species, namely, the fact that the angular depressions in the crowns of the back upper molars communicate across the teeth, forming transverse loops instead of lateral triangles, I incline to agree with Coues in consid- ering abnormal. ON ARCTIC CHARACTERS OF THE SURFACE FAUNA OF THE BAY OF FUNDY, AND THE CONNECTION WITH A THEORY OF THE DISTRIBUTION OF FLOAT- ING MARINE LIFE. BY J. WALTER FEWKES. QEVERAL naturalists have shown a similarity between the fauna of the Bay of Fundy and that of the waters of Labrador and Greenland. This comparison is of great interest to students of New England marine zoology. As the evidence thus far adduced is mainly drawn from studies of littoral animals, it has seemed in place to test the theory by a consideration of oceanic genera. It would be pre-eminently fitting to consider floating marine life with this thought in mind, and as the young of a large number of marine genera are free-swimming, . 602 Surface Fauna of the Bay of Fundy. it would be well to include them with true oceanic genera in this connection, I undertake this comparison with more enthusiasm, as it has been my good fortune to examine and publish notices of nomadic animals which have been collected in high latitudes by Lieutenant Greely, and since it has been possible for me to study the marine life of Grand Menan and the islands off the coast of New Brunswick.’ A study of the surface life of the Bay of Fundy reveals inter- esting facts in the theory of the Arctic relationship of the life of these regions. | Nomadic animals which live in the high seas, generally upon the surface of the ocean, are known as pelagic animals, and consti- tute what is called the pelagic fauna. While this fauna is pre- eminently the fauna of the ocean and is found best marked at a great distance from the land, it often happens that winds and cur- rents sweep its members into our bays and harbors, and we in this way become familiar with it. Like all large bays with open access to the ocean, the Bay of Fundy has a pelagic fauna. It is, in fact, the same or nearly the same as the pelagic fauna of the coast of Greenland. Animals which are strictly pelagic are never limited to the coast, to the littoral fauna, or to the sea bottom. They never become attached, but crawl about, or rest upon the sea floor, A large number: of marine animals have young which resemble pelagic organisms in these nomadic habits. They also wander about and are carried hither and thither by ocean currents independent during their youth of the coast or the sea bottom. As they reach maturity, however, they sink to the sea floor, and there remain, either attached or limited in their movements toa small area. These young or larve, as they are called, may also be included in the pelagic fauna as long as they preserve this free-swimming feature. This larval and adult pelagic fauna differs in different regions of the ocean, and that of the Bay of Fundy differs in a marked manner from that of the bays of southern New England. : A study of the pelagic fauna of the Bay of Fundy shows that it has a boreal character. While it is in many respects like that of 1 I have already elsewhere (Bull. Mus. Comp. Zool., vol. xiii,, No. 6) considered the boreal relationships of the medusan fauna of the Bay of Fundy. Surface Fauna of the Bay of Fundy. 603 Massachusetts Bay, it is in marked contrast with that of the bays south of Cape Cod. We may, in fact, say that the fauna of the Bay of Fundy is more closely allied to that of the coasts of Greenland, as far as its pelagic life is concerned, than it is to that of Narragansett or Buzzards Bay. The reason for this diversity in the inhabitants of bodies of water so near together, and the resemblances of faunæ of localities so far apart, may easily be found in the direction and character! of oceanic currents to which the distribution of marine life is almost wholly due. Moreover, the surface life is in a measure dependent on the amount of water brought to the coast by the tides. The greater the volume of water which sweeps into the bay, the larger the number of animals which it brings with it, if other conditions remain constant. The great tides of the Bay of Fundy are admirable for the purpose, and they bring to the shores of New Brunswick a wealth of surface life seldom equalled and never excelled elsewhere on the coast. There is a strict line of demarcation between the surface fauna found south of Cape Cod and that immediately north of the same headland. It would seem the most natural thing in the world that an animal which passes its life floating or swimming on the surface waters of the ocean should live equally well in Narragansett Bay or the Bay of Fundy. That is, however, not the fact, for while stragglers from the true Arctic faune of the waters of New Brunswick may sometimes be found at Newport, there is as marked a difference in the facies of the faune of the two regions as between those of the two sides of the Isthmus of Panama. Why is there this difference? : The answer is found in those limitations in the distribution of animals brought about by the differences in the temperature of the sea. Everyone who has tried the ocean bathing in these two localities knows how much warmer the surface water south of Cape Cod is than that of Grand Menan, and this difference of tem- perature means life or death to the delicate creatures which live in it. The animals south of Cape Cod are those of warmer waters, and some of them have their home in the Gulf Stream, while those in the Bay of Fundy are pre-eminently of polar origin, and can endure with impunity a fall in temperature which would kill the ! The boreal life of the Bay of Fundy is thought to be due to the Labrador current, 604 Surface Fauna of the Bay of Fundy. inhabitants of the Gulf of Mexico. As the study of animals which are not nomadic teaches that those of the Bay of Fundy are most closely allied to the inhabitants of the colder waters of the Arctic, soit is with the surface life. Both tell one and the same story, that the assemblage of life in the sea which constitutes the fauna of the Bay of Fundy is Arctic in its affinities. To demonstrate the Arctic character of the free-swimming life of the Bay of Fundy would seem to necessitate a minute comparison of faunal lists from the two localities. It is not wholly necessary for our present purposes, however, to make such an extensive comparison. Some of the more striking instances of floating boreal life will suffice. Of all floating animals the jelly fishes are well suited for this study. Among the Medusze we have marine animals, as well known as any, from which to test our theory. The following may be mentioned as some of the Medusæ of the Bay of Fundy which are markedly Arctic. The large and beautiful Cyanea arctica, one of the most stately forms of discophorous jelly fishes, is pre-eminently an Arctic genus. Callinema, first described by Professor Verrill, another large Medusa of the same group, and has never been seen south of Cape Cod. Among Hydromeduse the beautiful Turris episcopalis is boreal in its distribution, and rarely gets south of the coast of Maine. Staurophora and Halopsis are northern genera. The beautiful “ sea necklace,” Nanomia cara, one of the most exqui- site genera of marine animals, has been seen in the icy waters of Robeson’s Channel by Arctic navigators. It is rarely seen south of Cape Cod, in Narragansett Bay, but at Grand Menan hundreds of specimens, some of which were four feet in length, were taken from the landing places, and at other points on the shore. If we, in fact, take the faunal lists of the Meduse of the Bay of Fundy and compare them with those from Greenland and neigh- boring waters, we find, as far as our knowledge goes, a strong resemblance between ie medusan life in the two regions. of course there are genera occurring in the waters of Greenland which are not to be found in the Bay of Fundy, and vice versa, but that does not change a belief in a general statement that the marine animals of the two localities resemble each other in facies. If we 1 The surface animals of the Bay of Fundy, although Arctic, are not supposed to be of the extreme polar types. For obvious reasons s little is known of the facies of polar marine life, Surface Fauna of the Bay of Fundy. 605 should carry our comparisons of the surface life of the two locali- ties among other groups, we should find as marked a similarity there as among jelly fishes. One or two examples may suffice for illustration, There is no pelagic mollusc which is more truly boreal than the well-known Clione borealis This pteropod rarely ventures into Narragansett Bay, is more common as we go north, and was at one time observed in great abundance in the Bay of Fundy. In the North Atlantic and on the shores of Greenland it is found at times in countless hosts. Among the pelagic annelides, one of the most common at Grand Menan is a species of Sagitta, which bears a strong resemblance to a Sagitta found in Lady Franklin Bay by Lieutenant Greely. This Arctic Sagitta is markedly different from the Sagitta of Narragansett Bay. The species of Appendicularia found in the Bay of Fundy is different from that of Newport, and appears to be the same as that recorded by Murdoch from Point Barrow. This pelagic ascidian, as is well known, is found in some places enclosed in a gelat- inous envelop called the “ haus,” which serves ‘as its protection, or for other purposes. Although I have repeatedly taken Appendicu- laria in Narragansett Bay, I have never found the “haus” in those waters. From Murdoch’s description of the Arctic Appendicularia and from its size, I am inclined to think that the Bay of Fundy Appendicularia? will also be found with houses. The mere fact alone that the Arctic Appendicularia has the house, so-called, is not characteristic, for animals of this or allied genera in warmer waters have the same structures, The resemblances between these two marine faunæ suggest inter- - esting general questions of distribution. Students of the geograph- teal distribution of terrestrial animals easily recognize the facies of organic life from different continents. A collection of the land animals of Australia has an altogether different appearance from ene from Europe, while those from South America are different ftom those of North America. While the characters which impart | I have taken many specimens of the larva at Newport. * It is undoubtedly true that the Bay of Fundy Appendicularia is a different species or even genus from that of Narragansett Bay. It Closely resembles the genus Oikopleura. 606 Surface Fauna of the Bay of Fundy. this difference are hard to define, they exist and are recognizable by a specialist. In the Museum of Comparative Zoology at Cambridge this difference is shown by faunal assemblages of life from different regions of the globe, each arranged in different rooms, known as the North American, European, African, ete. The idea is a grand one, and to a student of physical geography of the greatest importance. As in the study of land animals there is a different facies to the assemblages of life from different quarters of the globe, so in the ocean there is a different facies in collectious of animals from different regions of the sea. Place side by side a number of Arctic species of shells and those of the same genera from the tropics. If the shells be representative, the conchologist need not hesitate long as to their homes. The dull,cold, little variegated molluscs of the Arctic contrast markedly with the brilliant, gaudy shells of the warmer zones. Passing to the inhabitants of the ocean, the deep-sea animals have an altogether different facies from the surface animals. The characteristic facies of great regions of the ocean are as noticeably different as those which naturalists have long recognized «mong terrestrial animals. It is not in place here to point out the different regions into which the oceanic faunz may be divided, but it would be interesting in considering the causes of the boreal character of the pelagic life of the Bay of Fundy, as they involve a general con- sideration of the laws which have led to the diversity of these faunæ. I consider the temperature of the water as a most import- ant influence in causing the diversity of life in the ocean. Varia- tion in temperature is probably more important than pressure in the bathymetrical distribution of deep-sea life. The difference in temperature of the surface of the ocean is one of the most importan factors in determining the character of pelagic organisms. As we have a variety in surface temperatures, we have a diversity in the surface fauna. We have, it is held by some, a repetition of Hum- boldt’s law of the modification of plants in altitude, and the corre- spondence of latitude with altitude, in a change in character of animals by depth resulting from several conditions, among which may be mentioned pressure and temperature. Whenever the tem- perature of the deep-sea becomes a surface temperature, as in the Arctic Ocean, then, it is argued, we may look for allies of deep-5e@ animals. Surface Fauna of the Bay of Fundy. 607 The two great tendencies at work in the modification, as in the geographical distribution, of pelagic animals, are cold currents of water bringing them into lower and warm currents transporting them into higher latitudes.! The physical result in both instances is a change in the temperature of the water and other conditions in which they live. Where the currents generally set from the south to the north, as on the eastern coasts of the Northern Hemisphere, we may expect a relationship to the tropics in higher latitudes than where the currents are from the pole. The former currents carry the warm belt into higher, while the latter restrict it to the lower latitudes. It is known that the distribution of coral reefs on the western and eastern coasts of the continents has a direct relation- ship to the direction of the ocean currents, and that where the current is from the equator to higher latitudes (Eastern coasts) coral reefs extend farther from the equator than where the general direction of the oceanic rivers is from colder to warmer latitudes? This can readily be seen by consulting a map of the earth’s surface where all the great coral reefs are on the eastern side of the con- tinents, and where also all the great oceanic currents are setting from the equator towards the poles, This law in the distribution of corals, pointed out by Dana, is believed to hold also in the case of other animals, which, unlike corals in their mode of life, are not fixed, and have left no hard secretions to denote their former or present existence. It will be seen by a consultation of Kriimmel’s maps of the distribution of surface temperatures in the Atlantic, and by a reference to the chart of the surface temperatures published in Science for December, 1887, that the Bay of Fundy does not lie in the same isothermal zone as do the waters of the coast of Greenland. Perhaps these zones were only intended as approximations, and the temperature of the water of the Bay of Fundy may not be higher than of that of the coast of Newfoundland. In the chart referred to, the Bay of Fundy is near the southern limit of the zone of low surface temperature, and the high tides may account for the large percentage of boreal surface animals in its waters. aipa — life washed to the coast of England will probably be pate - from that of Labrador under the same latitude. i y due also to the food of the coral, minute floating life, which 18 furnished in greater abundance on account of the currents. 608 Surface Fauna of the Bay of Fundy. The student of the geographical distribution of pelagic life will, I believe, find a correlation between the facies of this fauna and the zones of equal temperatures of the sea. An improvement in the projection of these zones on the maps of oceans will lead to a corresponding advance in our knowledge of the distribution of marine life characteristic of the surface of the sea. If we accept the proposition that the pelagic fauna of the Bay of Fundy is Arctic in its facies, it becomes an interesting thing to study carefully this fauna in its relation to animals found in deep-sea.! Is there a closer affinity between animals found on the surface of the ocean, where the water has an Arctic temperature, and those of the deep water where the temperature is the same, than between those of the surface of the ocean in the tropics and deep water, where there is a marked difference in temperature? Although marine zoology has never been a primary object of polar exploration, it is probably true that most interesting results are to be looked for if the attention of Arctic explorers is turned to the importance of this study. Let me call to mind one interesting aspect of the study of marine ani- mals from polar regions. Now that the character of the deep-sea fauna may be said to be known, as far as its general facies is con- cerned, it may be well to ask whether there are any places on the globe where conditions found in deep water are repeated in shallow seas, and where there is a similitude in the environment under which life exists. There are two conditions under which deep-sea life is placed which may be considered. The first of these is pressure, a condition which we can normally expect to find only in the sea at great depths ; the second is a low temperature of the water which exists in certain oceans at the surface? A third condition, viz, the amount of light, is in a way connected with the second. In my consideration of the subject it is not discussed. 1 The explanation advanced by physical geographers that cold waters near land are sometimes due to a replacement of surface waters by those from great depths may explain many peculiarities in the dis- tribution of life. 2 Murdoch’s record of pelagic animals taken from the Arctic Ocean when the temperature was 29.1° F., is among the most valuable which have been made on the character of pelagic life in water of this low surface temperature. If they are not the first observations on this sub- ject, they are certainly the most complete. Surface Fauna of the Bay of Fundy. 609 In many invertebrate animals the difference in pressure at 1000 fathoms and at one fathom is endured with impunity by the same species. Difference in pressure under which a deep-sea animal is placed is not believed to be the influence which is most important in the determination of the limitation of deep-sea faunæ to certain depths. Invertebrate animals, however, which can endure equally well enormous pressures or live near the surface without harm, are delicately susceptible to a change of temperature of a few degrees. Temperature has drawn even in littoral zones invisible limits or lines of demarcation, which are partially known to naturalists. The laws of the diminution in heat with the depth has also been shown. It is known that the bottom temperatures of deep-seas are surface temperatures in some parts of the globe. If temperature. is an important condition of the environment of deep-sea animals, it is significant to discover what the character of the marine life is in latitudes where the temperature is that of the deep sea and where it is constant. The polar oceans show on the surface of the water the low temperatures of the deep seas. Those temperatures, to find which in tropical oceans the plummet has to go many fathoms below the surface here come to the surface, and are its ordinary temperature It is interesting to discover whether in places widely separated in latitude, but where the temperature of the sea is the same and constant, we find any uniformity in the ocean fauna. It must be recognized that we have in the great body of water which com- poses the ocean a mass of liquid, the temperature of which is modified by local currents, vicinity to the land, and other conditions. As a general law, to which there are some exceptions, it may be said that the temperature of the sea decreases as we sink below its surface, Of all places in the ocean, where the limits of variations sB temperature are small, none equals the deep water. A maximum variation in the tropics may be found on the surface and in the neighborhood of the coast line. The minimum is far below the surface in the deep water. It may readily be imagined that, if there were no distribution of heat in the ocean by currents as we go north or south from the equator, we should find the isothermobatric lines, or lines 610 Surface Fauna of the Bay of Fundy. of equal deep-sea temperature, gradually approaching the surface of the sea until we come to the icy waters of the pole. Here we should find a law of the distribution of heat similar to that which holds on land, where there is a constant relationship between the altitude above the level of the sea and the latitude as far as the diminution in temperature is concerned, unless modified by local conditions. As we ascend the tropical mountain the heat, as a general thing, diminishes; the same is true as we go below the ocean. As we increase our latitude in either case, the temperature follows a common law in its change, approaching pari passu the level of the sea. It was long ago recognized that the distribution of plant life on a tropical mountain is correlated with the change in temperature, and that in ascending a tropical mountain-side we pass through the three climati¢ zones. The author does not know how far this theory is now accepted by botanists, but it is interesting to see whether a similar law holds in the ocean where there is a like change in temperature. We know that there is a peculiar fauna of those animals which habitually live on the bottom in the deep sea. We know there is an sequatorial marine life which is confined to the surface of the ocean, represented by Physalia, Veleila, and others. Associated with the latter are other genera, as Afolla, which some- times go down to 1800 fathoms below the surface. Are there any meduse at 1800 fathoms which rise to the surface without destruc- tion? I.think there are, although our facts are not decisive enough to prove it.! I also believe that there are nomadic deep-sea animals which in the tropics cannot rise through the stratum of warm water above them without harm, but it by no means follows » that where these low temperatures of the deep seas become surface temperatures they may not come to the surface of the sea. It seems probable that the cold areas of deep seas have pre- served uniformity of environment for a much longer period of time than warmer areas of the surface. ‘The water of the ocean in differ- ent strata is, of course, varying its temperature, but there are certain positions where an almost uniform temperature has been kept up for long periods of time. The uniformity of conditions 12 1 Since this was written a large number of observations by Chun have shown the truth of this belief. Surface Fauna of the Bay of Fundy. 611 the cold polar seas, as far as temperature of the water goes, is greater than under the equator at the surface.. Consider the waters of the polar ocean covered by a paleocrystal ice, and those unpro- tected under the burning tropical sun. In the one there is certainly a minimum of variation in temperature, in the other a maximum, as far as the water is concerned. If environment, if uniformity of conditions, has anything to do with variation in forms of life or with the preservation of ancestral features through long periods of time, should it not appear in the animals which live under these conditions ? There is a certain parallelism in the animals of cold and warm oceans and those of deep seas and littoral zones. It is, of course, impossible to link together what we know of deep-sea life with that of the polar region with any hope of a satisfactory answer as long as our knowledge of either is incomplete. Fortunately the character of deep-sea life in late years has been investigated. As far as this problem goes, the least satisfactory part is that which pertains tothe nomadic deep-sea genera. With regard to the marine life of the polar regions, where the deep-sea temperatures become surface tem- peratures, much remains to be done. We know the littoral marine Invertebrata of the polar sea better than those of many bays con- tiguous to our own eountry, but the subject of the marine surface fauna is yet to be more fully investigated. If polar exploration is to be continued, as there is no doubt that it will be, a more com- plete study of the marine life would be an important object of such exploration, and would be of value to our knowledge of the geo- graphical distribution of marine animals. It would be interesting to take up again the somewhat threadbare discussion of a relation- ship between the Arctic and deep-sea faunae. It might verify a prediction that it is possible to recognize ancestral forms among those Which people the icy waters of the polar seas. The theory of the Arctic character of deep-sea faunæ is by no means a new one, and as long as the zone of deep water from 100 to 300 fathoms was studied there seemed to bea marked likeness between these two fauna. When, however, the variegated fauna of the abysses of the ocean came to be studied, it became more difficult to found resemblances between deep- Sea animals and those of the poles. Our comparison of deep-sea floating life with the polar introduces a new phase in the discussion, 612 Cerebrology in Phrenology. as the animals which we are considering are not attached, but are nomadic in nature. There is nothing to prevent a comparison between the nomadic life of deep water and that of the Arctic, even if the facies of the abyssal zone is different from that of any oceanic fauna of the globe. While the difficulties in the investigation of the animals of the polar regions are such that much remains yet unknown in relation to the surface life of these latitudes, the similarity of that of the Bay of Fundy to it, if such a likeness really exists, renders this study comparatively easy. It becomes imperative, then, to know accurately the facies of this fauna if one would use this knowledge in comparisons with deep-sea faune. CEREBROLOGY AND THE POSSIBLE SOMETHING IN PHRENOLOGY. BY S. V. CLEVENGER, M.D. ee years ago, in the American Journal of Nervous and Mental Disease, I reviewed the history of brain studies, from Erasis- ratus to Ferrier, and described the conyolutions and fissures with their equivalent names as used by English, German, French and Italian investigators. Microscopic details had at that time added immensely to our knowledge of the structure of this important organ, but since then pathological and physiological science has cor- rected many of the errors prevalent and improved our understand- ing of the localization of function. When it was established that arm, leg, tongue, ear and eye cen- tres were distributed about the brain cortex, beneath alleged bumps of conjugality, appetite for music, theology and onions, phrenology was discouraged except among its more ignorant devotees. At the conclusion of a popular lecture on the anatomy and physiology of the brain I was assailed by an itinerant phrenologist who did not relish his dollar-a-head prospects being jeopardized by the spread of my heresies. He offered to stake money on the infallibility of his “science” in a public demonstration, and when told that phre- nology had been written up in a form available for criticism and Cerebrology in Phrenoiogy. 613 found to be defective, he warmed to the conclusion that he could lick any one who opposed phrenology with such “ ipsy dixys.” Gall and Spurzheim are always cited by phrenologis.s as the founders of their system. While this is true, and it is also undoubted that they were in advance of the early part of this cen- tury in brain anatomy and philosophical guess work of brain func- tions, it is forgotten that but few anatomists of note have sustained the theories that have been piled upon the fairly well done work of a time when brain study was infantile. The ignorance of those who practice phrenology as an art, their illogicality, impudence and . rapacity for fees, the fact that phrenology stands isolated from all the sciences, having nothing to do with physiology, chemistry, microscopy or pathology, as cerebrology has; its frequent defiance of exact knowledge which negatives the pretensions of bumpology, —all relegate phrenological claims to an equality with those of spiritualism, Christian science, jugglery and the multitude of penny- catching devices of an age of never-failing crops of knaves and fools. There is nothing like a good knowledge of physiology to destroy charlatanism and the superstition upon which it fattens. But alchemy gave us some chemical facts, and astrology was mixed up with a few astronomical truths. Psychical research societies are trying to examine prestidigitation as one would study the mechanism of a watch through its key-hole, and it seems to me that patient study can be applied profitably to an examination of moribund old phrenology. The tendency was extreme to locate pin-head points on the cra- nium that would reveal such things as whether one preferred coffee to tea; but, starting with the admission that there is a little truth m phrenology, in a general way, we are also confronted with the fact that, no matter how it is done, there has been some pretty shrewd guessing at character by even ignorant phrenologists. Their physiognomy studies are incomparably inferior to those of Darwin, or even those of the windy Lavater. Every one is an unconscious Physiognomist without having analyzed expression ; phrenologists make use of this common ability in estimating character. But this does not include their entire method, as they often hit off traits more happily than mere expression would enable them to do. First of all let us glance at what is really known about heads 614 Cerebrology in Phrenology. and their contents, and then see how much of phrenology can be adjusted thereto. Prognathism and acuteness of Camper’s angle are well-known indications of less intelligence. Apes also have less skull capacity with larger and more numerous ridges for muscle attachment. The European has a characteristic medium (mesocephalic), rounder, oval or elliptical head, with no portion too prominent or flat, presenting.more symmetry of contour, with oval face and full, expanded, elevated forehead. Want of symmetry, if marked, attends mental defect, but it has occurred in highly gifted men such as the French anatomist Bichat. No two heads are exactly alike any more than are two faces. The proportions existing between the front, middle and back parts of the head are of some value; departures from a width of eight and length of ten (mesocepha- lism), measured from one auricular aperture over the head to the other, and nose root over the head to the nucha, determine whether the skull shall be considered long, dolichocephalic, or broad, brachy- cephalic. The front expanse is associated with a possible reasoning power, the back part with animality, but as this is necessary to force of character, a well-balanced head would be one that had a fair size of both parts. As the frontal bone is elevated the parietal must be raised to meet it. The artist Haydon, by cutting off this parietal raise, showed that the head was reduced from an intellectual to an animal appearance. Scaphocephalism, or a boat-shaped depression of the summit, occurs from defective parietal bone formation. The Kalmucks incline to brachycephalism, while the negro 1$ dolichocephalic, with prognathous jaw, large temporal and auricular muscles and low foreheads; the Esquimaux are tectocephalic (rafter- headed), with flat, pyramidal or lozenge-shaped faces, due to exces- sive zygoma projection, and narrow foreheads. Carpenter notes that want, squalor and ignorance diminish the cranial and increase the facial size. With increase of intelligence there is a larger brain mass in pro- portion to the muscular size, and also to the size of the spinal cord and peripheral nerves. I claim priority! in adopting the sulcus of 1 Sulcus of Rolando and Intelligence. Written Feb., 1880. Journal of Nervous and Mental Disease, April, 1880. : Cerebrology in Phrenology. 615 Rolando as a means of estimating grades of intelligence in animals by the relative masses of brain parts it separated. Meynert! had, unknown to me, nearly simultaneously, stated that the angle at which the Rolandic departed from the Sylvian fissure was a meas- ure, but in this he is in error, for that angle is not constant for spe- cies, while the relative proportions of fore and rear brain divided by the Rolandic sulcus maintain a just ratio to grades of intelli- gence, and the left suleus summit should be farther back in the normal brain than the one upon the right side. I also claimed that the cerebellum was covered by the cerebrum in proportion as the frontal lobe developed and crowded the occipital portion backward, = forehead by this pressure is correspondingly expanded and ifted In the scale of higher intelligence the connecting commissures of the brain are more numerous, and the cortical gray matter is encroached upon by more cells and fibres. Convolutions are not necessarily more numerous, except where the cranium is relatively small and the soft brain tissue by rapid growth folds in to accom- modate itself to the want of corresponding skull growth. Á In accord with the results of earlier electrical experiments upon T brains of anthropoid apes, dogs and other animals, are e effects of disease limited to special parts of the brain of man, ? Archiv für Psychiatrie, vii. 616 Cerebrology in Phrenology. more recently and thoroughly studied. We now know that there are centres in the brain of man for the speech faculty above the temple, and thence backward and upward to the upper back part of the head are arm and leg centres; auditory mental impressions being registered in the brain above the upper ear tip; a centre for visual function being in the occipital end of the cerebrum. The frontal brain is known to contribute to intellectual processes, for its injury degrades the character. This approximately sketches what has become positively known, and the illustration further assists the comprehension of these facts. The touch sense centres are distrib- uted over the brain coincidentally, with motor centres for the same parts, i.e., arm motor and sensory areas are in the same part of the brain. Spaces intervening between the areas may readily be conceived to be filled with fibrils and cells that interrelate these and other func- tions complexly, the frontal portion compound complexly. Sir Charles Bell remarked that “ we ought to define the hand as belonging exclusively to man.” Upon the increased dexterity in the use of fingers in the arts and sciences, which dexterity, in turn, develops brain centres, depends, largely, increased intelligence. Manipulation and vocal training enlarge the “symbolic field” of the brain (the speech, arm and leg centres before mentioned), situ- ated along the sulcus of Rolando. Man is distinctively the sym- bolic animal, and whether these symbols are written, spoken or ges- ticulated, they serve purposes of intelligent intercourse, and upon this fact is based man’s supremacy over other animals, and his higher faculties are superimposed thereupon. When the portions of the brain allotted to control of body extrem- ities are diseased, the dependent loss of function follows, but not necessarily involving mental loss; for example, if the injury is * the summit of the sulcus of Rolando, upon one side of the brain, the body is paralyzed upon the opposite side. The “blank spaces” between these centre areas afford debatable ground, for often injury in such parts has been followed by no discovered consequence. My opinion is that the effects have not been looked for in the proper direction ; for, while destruction limited to these blank parts does not occasion loss of observable function (the arms, legs, speech may be unaffected), there will be found an attendant lowering of the Cerebrology in Phrenology. 617 mentality in some or several directions, if thorough tests be made. What has been grouped under change of character should be sifted to ascertain what constitutes the change. If we grant, as we must, that all these function areas, ascertained to be such, are related, con- nected, by multitudes of strands and cells in the most complex man- ner over and across the blank spaces, then lesion of those spaces must interfere with the connections, the mental associations possible before cannot now be made. Occasionally “word deafness” or “word blindness” occurs, peculiar inability to connect words heard or read with any memory of their import, and, as could be expected, this impairment occurs when the lower parietal or “angular gyrus” region is the seat of the disease. While this consequence of injury to this part has been long known, I believe this to be the first announcement of the reason for it, and I will predict that the addi- tional offices of this “blank area” will be established as noted below. “ Arcuate ” connecting fibrils enmesh the brain surface, uniting faculties intricately, in a manner obviously dependent upon the education and other circumstances of the individual. These fibrils and their generating cells may pile up in certain parts and be defective in others ; the musician will have more connections between the auditory and motor centres, and the painter between the optic and motor, than others. One whose impulses or springs of action are well subordinated to what he has learned through optic, auditory or other senses, will have greater strands of connec- tions between the sensory and motor brain parts to regulate his deeds than the impulsive or heedless person. These blank spaces become what might be styled inhibitory regions, in that they restrain acts; they can also more properly be called impulse areas, because they regulate and prompt actions. As. they correlate the sense and motor centres, they are also memory areas, as is evident when injury causes words to convey no meaning to the mind. Now, if what we see, feel and hear govern our actions, he who profits best by what he has been taught, or upon whom such teaching makes the best impression, will, à priori, have — the most abundant supply of arcuate fibrils in this parietal region ; such restraint or guidance unavoidably causes acts to be less impul- ‘ive, more subordinated to the interests of the individual. If those needs are considered to be best conserved by subservience to others 618 Cerebrology in Phrenology. their approval will tend to regulate acts, a form of cautious defer- ence dominates the person; if a wider, higher and better form of cautiousness, based upon what one considers his highest interests, is higher expediency ideals, whether with reference to this or another world, then the person is said to be conscientious. At this stage of analysis of what these inhibitory or impulse connections involved, I was astounded by recalling that phrenologists group “ conscientiousness, approbativeness and cautiousness” in the iden- tical place under discussion. The process of arriving at this dis- covery was by first recognizing inhibition to be but cautious con- trol, and I have long held the idea that conscientiousness was but a higher caution.’ Startled by noting that phrenologists place them next one another, as they assert, empirically, they having found these eminences to be prominent in persons who were thus scrupu- lous or guarded, I next observed that “approbativeness”’ is placed behind, but adjoining “caution and conscientiousness.” This nar- ration should acquit me of special pleading. Disposed unfavorably, as I was and am, against phrenology, as in the main a pseudo-sci- ` ence, my aim has been to unsparingly criticize it. This group of alleged bumps in the position the phrenologists assign it is a remarkable coincidence, if it prove to be no more. I prefer the designation Impulse and Memory region until more scientific men than phrenologists agree upon the separation of the area into the divisions, “ cautiousness, conscientiousness and appro- bativeness,” which cannot be done until we ascertain whether phre- nologists lied, were mistaken, or were right in this particular. “ Firmness, Self-esteem, and Continuity” are placed by them over the tonsure or earliest bald spot, beneath which in the brain is the summit of the Rolandic sulcus, injury to which invariably causes paralysis of the opposite side. We can concede that an abundance of arm and leg centres in this region would indicate the possession of self-reliance, nor would it be far-fetched to interpret such control as firmness, scoring another for phrenology; an excess of this might be construed into self-esteem, and if the motor area (as in fact it does sometimes) extend farther occipitally, then this brain centre increase of cells and fibrils serving for better innerva- tion of arms, legs and other parts, might be allowed to constitute ı Comparative Physiology and Psychology. A. C. McClurg & Co., 1884. Cerebrology in Phrenology. 619 “continuity ” in enabling more prolonged effort. Coincidences that may be justified by a real relationship. Quien sabe? Below and toward the front is “ Hope.” If thought has its main seat in the frontal region, a prolongation of fibrils thence to control acts with a definite expectation in view, anticipation based upon reason, might justify some such bump as this, and in about that location. “Ideality” seems better placed, farther forward, for a similar reason, and not open to the objection of being located over arm and leg centres, as is “ Hope,” although arcuate fibrils having many destinations may overlie any part of the brain. “ Benevolence” is placed near or over the anterior fontanelle. As this trait is the outgrowth of sympathy, an acute feeling for others depending upon a thoughtful correlation of past experiences or impressions inherited or acquired, so there may be such a swell- ing in that vicinity. “Constructiveness” is over the third frontal convolution root, which, on the left side, is the demonstrated seat of language, so the bump is mislocated: A rounding out ef the side head above and forward of this could indicate the possession of such a faculty, because it depends upon ingenuity, mechanical ability, etc., a brain and mental breadth. “Eventuality, Comparison, Causality, Individuality,” in the frontal apices, apparently appropriately enough, for cerebral reasons, The claim that “Amativeness” resides in the cerebellum has been sufficiently disproved by the experiments recorded in Car- penter’s Physiology, where the cerebrum, and not the cerebellum, decreased in size with sexual loss. Furthermore, the cerebellum has no relation whatever to the posterior protrusion of the skull. A large muscular development is an indication of animality, which may be offset by intellectual balancing. Large trapezius and sterno-cleido-mastoid muscles would have a correspondingly large occipital ridge, and it is over this that the phrenologists locate ‘ Amativeness,” _ The animal propensities, “Combativeness, Secretiveness, Destruc- tiveness, Alimentiveness and Acquisitiveness ” are suggestively gathered over the temporal and auricular muscles, as these mus- cles are large in rapacious animals. Without admitting the spe- 620 Cerebrology in Phrenology. cial divisions, these animal traits undoubtedly could accompany extra prominence of these muscles in the place assigned to these faculties by the phrenologists, while there is not a cerebral or cra- nial warrant for the location, palpably when beneath this muscu- lar swelling the skull is often depressed to afford it attachment. “ Alimentiveness” is appropriately placed over the temporo-max- illary articulation ; a great eater works this vicinity more, and thus may increase its size. The superciliary ridge may be enlarged by serviceable and asso- ciated habit in shielding the eye, frowning while trying to per- ceive better, and thus indicate perceptive acuteness, but the sub- divisions into size, color, etc., require demonstration, as extremely doubtful. : “Form” is said to be shown by width between the eyes. I know good artists who have not this width, and execrable ones who have it. Language does not produce cedema of the lower eye-lids; the faculty is remotely and surely situated under the alleged “ Constructiveness. It would not be profitable to discuss the other bumps, as they seem rather absurd. We thus alight upon three main character indications, due to brain, skull or muscle prominences, which the phrenologists errone- ously call cranial, and regard the brain as the cause of the skul elevations.

The cognitions similarly classified end in the highest of all, being placed in the apex of the frontal lobe, the re-representa- tive cognitions, aggregations of representations, the appreciation of the general relations of things. There is something beside generalizations in phrenology hidden beneath a load of trash. In shoveling this away scientific men are apt to jeer the labor ; they can be as mulish as the most ignorant In refusing to see what they do not want to know; they are human, as witness the reluctance with which the majority accepted Dar- Winism, though emanating from a reputable source. It should not be forgotten that phrenology was founded by good anatomists, and that scientists turned against it because charlatans built error upon it; but quacks have taught us a few things worth knowing. 622 Observations made in the Central Philippines. OBSERVATIONS MADE IN THE CENTRAL PHILIPPINES. BY J. B. STEERE. sas islands of Panay, Guimaras, Cebu and Bojol may well be grouped together and called the Central Philippines. They are geographically connected ; their people are of allied races and language, and, as we found, they are closely allied zoologically. With Mindanao on the south, Palawan on the west, Masbate and Mindoro on the north, and Leyte and Samar on the east, they are separated from all these by broad straits, while the channels divid- ing them among themselves are at their narrowest points nowhere more than five or six miles of continuous sea, and this usually shallow and apparently rapidly changing hues, so that the land areas must have been very different in size and form ata very recent period. — We arrived at the end of December, 1887, at Ilo Ilo, the cap- ital of Panay, and the principal trade centre of the surrounding islands. Soon after we moved over to a pleasant native house on the island of Guimaras opposite. The place was on thé beach, at the foot of some steep! cliffs of coral, a little brook came tumbling down at one side, while a fine grove of cocoa palms shaded the house. The woods were near, and beautiful sun birds and Diceeums were flying about the palm houses, while several of the most beautiful species of the famed Philippine tree shells were found in abundance on the barn door and other outhouses near by. We were near enough the city to get a supply of fresh meat and bread every morning, and it was the nearest a naturalist’s paradise we had yet found. The birds as they came in, though of genera we had already become familiar with in the west and south, were most of them of different species, showing that we had reached 4 new and distinct area, _ The west side of the island is made up of steep, rugged cliffs of limestone, which rise up from two to three hundred feet above the sea. The rock has weathered into crevices and holes, leaving Observations made in the Central Philippines. 623 sharp points standing up, which makes transit very difficult. Inland this rock is broken up by narrow, steep valleys, through which flow the little streams from the centre of the island. The cliffs are full of caves, which seem in most cases to be water courses cut through the rock. We had heard of nests of the edible swallow (swift) in the island, and finally found a wrinkled old Indian who made a living by gathering the nests and selling to the Chinese at Ilo Ilo. The nests are not found, as might be supposed, in those caves opening near the sea, but in those far inland, where the cavity is covered with forest. We went to the nest-gatherer’s hut, two or three miles back from the sea, and telling him our object, he provided himself with a torch of native gum (dammar) and another made of the ribs of cocoa palm leaves, and we set out. After half an hour’s rapid tramping through the steep, rocky valleys, we came to a low ledge of rock, eight or ten feet high, covered with vines and bushes, and at the foot of this a black hole three or four feet square, leading down into the earth. The opening was just large enough to crawl through, but our guide lighted his torches, and getting down on hands and knees crawled in, and we followed, down a steep, narrow, rocky passage, the channel of a stream in the rainy season. It widened and grew higher as we went down, but was still nothing more than a rift made in the rocks, perhaps by earthquake, and widened by water wear. The rocks were muddy and slippery, and we followed our barefooted guide with difficulty. Still on we went, until all trace of light except from our torches was gone, and it seemed anything but a fitting place for birds’ nests. Still we went on, until after we were perhaps a hundred feet below the surface, and several hundred from the mouth of the cave, we began to hear the weak, faint twittering of the little birds as they flew about over our heads, and finally the Indian raised his torch, and we could see in the roof of the cave shallow hollows in the rock, and in these, and partly supported by their sides, the little white, cup-like nests, which the guide began tearing out with his fingers, and stuffing into a pouch at his belt. The birds fluttered about almost in our faces, but he kept on until he had gathered all in sight. None of them had eggs in them, as he had visited the place but two or three weeks before. The nests were pure white in color, made of little fibres interwoven 624 Observations made in the Central Philippines. with each other, and were still soft and damp. How the birds had ever found this place so far from the light, with a dry face of rock, and with suitable digression in it was a wonder, and how they could do this work of nest building in such utter darkness. Coming to the surface we set out again, and after an hour’s tramp came to the second cave. This time as we were making our way down a steep, timbered valley, the path all at once dropped out before us, and we were at the mouth of a dark well, leading down almost perpendicularly for twenty or thirty feet at first, when the descent became more gradual. By clinging to the projecting rocks we clambered down, and soon found ourselves in a passage twenty feet high and as many broad. Great masses of rock had fallen from the roof, which made our progress slow. Curious stalactite growths, taking the form of flat plates with saw-tooth edges, were hanging from the roof. After making our way to a still greater depth and distance than before, we again heard the faint noise of the birds, not loud enough to be heard except in such perfect quiet as we were in. It seemed more like the sounds spirits might make than the notes of anything earthly. Soon after we came to a part of the cave where the roof was some eight or ten feet high, and worn into curious and very regular pits, five or six inches deep and as many wide at the mouth, and as smooth and round as if made artificially. In these the birds were building their nests, attaching ‘them to the walls of the pits. Again, in spite of the weak protests of the owners, the nests were torn out and appropriated by our guide. As we made our way out we passed a stalactitic column a foot in diameter, which had connected the roof and floor of the cave, but had been broken across by earthquake, and the ends separated by half an inch. The thought of being caught away in there 10 utter darkness by an earthquake, with the rocks grinding and shut- ting in upon us, was anything but pleasant. Near the mouth of the cave, just where we could begin to perceive a ray of light from the surface, were several nests of cruder, rougher make, bemmg much larger and made chiefly of grass and lichens stuck into the face of the rocks by large masses of the edible gum. The birds are, without doubt, of the same species. The guide said they were sentinels to alarm those within, and that their nests were always Observations made in the Central Philippines. 625 built in that way. The birds are quite abundant in the island, and there are probably many caves which the old man has not yet found. He is said to be the only one who dares enter them, others being deterred by stories of snakes, which are not all stories, for we passed, near the mouth of the second cave, the cast-skin of a snake eight or ten feet in length. There are also stories of a curious little black, hairy people, the Kama Kama, which are invisible at most times, and which inhabit these caves and live on the snails with which the island abounds. The guide pointed out great heaps of empty shells, far if the caves, as proofs of the existence of the Kama Kama, but they looked like shells which had been floated in by high water. The edible nest (swift) according to the guide, whose account was proved to be correct by our observations as far as they went, nests the year round, lays two small, white eggs, is about a month completing its nest, lays the eggs on the bird edible material of the nest, nests time after time in the same nest, adding to it each time. The young build beside the nest in which they were born, frequently attaching their nest to that of the parents, The only forest remaining in Guimaras was in the rough gorges and upon the rocky cliffs near the sea, the upper level of the interior of the island being sandy, and much of it in cultivation to sweet potatoes and Indian corn, and in the lower places to rice. The hills of Panay, all about Ilo Ilo, and as far up the mountains as we could see, showed no virgin forest, but only grassy slopes and bushy ravines, a poor outlook for our work. Whether the same conditions have worked like results elsewhere or not, there can be no doubt that the Indian method of cultivation has produced these grassy plains from an anciently heavily timbered country. They cultivate by cutting down the timber and burning it during the dry season, and then planting on the burned and blackened ground. One or two crops are raised before the wild growth gets too strong for their large knives, their only implement of cultiva- Som and then the timber grows again from the roots and sprouts left in the ground, and the cultivator cuts off another piéce of forest. After a few years, if the population is thick enough to demand it, the first piece, now grown up to brushwood twelve or fifteen feet > a 626 Recent Books and Pamphlets. high, is again cut and burned and planted, and so on over and over again, the tree growth beeoming weaker each time, until the coarse grass (cogon) gets in, and with it the annual fires, and then there is an end to Indian cultivation, and where were once tall forests, grassy plains take their place. This process can be seen on any island of the Philippines in all its stages. In some places the people are trying to overcome the cogon with the poor Chinese plows and the buffalo, but it is a slow way, and most of them prefer to move on to the fofests again. By this means the central islands, which are the most thickly peopled, have become for the most part covered with grass, while the more sparsely settled islands of the west and south remain in forest.

Asta, Erc.—Suanetia.—The first article in the June issue of i f M the Proceedings Royal Geographical Society is that o r ts 0. These glaciers send down to the Ingur or its tributaries many ice-streams, such as the Adish, which in the Alps would rank as a first-class glacier. On either flank of the rigid granites lie beds of friable schists, whose summits present green rounded out- lines, and exhibit a striking contrast to the snowy precipices of the great chain. South of Suanetia rises the lofty slate ridge of the eila, which runs parallel to the main chain, and attains elevations of 12,000 feet. At its western end this ridge bears some con- siderable glaciers. The river escapes from the valley at its western end, tween high spurs of the two chains, and through a narrow porphyritic gorge not at present passable for horses. To the east a valley of Suanetia terminates in a low grassy down (8,600 = only 1,600 feet above the highest villages, and beyond this les a pathless waste of forests and flowers—the wilderness in which Pui the Skenes Skali, a tributary of the Rion (the ancient hasis). But this outlet is so circuitous that both Russians and nea have preferred the higher and steeper Latpari Pass (9,200 eet), which is the usual route into the valley. e natives of this secluded spot are first mentioned by Strabo under the name of Soani, and the received text credits them with Pes ies fighting men. Strabo says that the king had a council of tk j and that the tribe used poisoned arrows in war. Whatever et ormer strength of the nation, the Suaneti, as they now call emselves, did not number more than 12,000 at the last census. ! Edited by W. N. Lockington, Philadelphia, Pa. 630 General Notes. Over one-third of these live on the upper Skenes Skali, and are more or less merged with the surrounding Mingrelian populations. The Suanetians are not in the odor of sanctity. At best they are sheep-stealers and cattle-lifters. They were converted to Christianity before the tenth century, but may now be fairly escribed as reverted pagans. Seven hundred years ago Suanetia formed part of the kingdom of the famous Georgian Queen Thamara, in whose honor the Suanetians still chant ballads. For awhile it was connected with Mingrelia, but at some time in the last century it became entirely unattached, and the upper part of the Ingur valley still bears the name o Suanetia. The country is covered with small chapels, dating probably from the 11th and 12th centuries, but these are no longer used as churches, but as treasure-houses. Long before Suanetia had obtained home rule, it had disestablished its church, An hereditary caste of local sisted in sewing together the garments of the bride and bride- groom, and the ancient funeral ceremonies were revived. There are traces of tree-worship and also of that of the heavenly bodies. The natural tendency of the population to increase beyond the ' supporting powers of the territory was effectually checked by placing a pinch of ashes in the mouth of every superfluous female baby- Russia assumed suzerainty over this district in 1833, and has gradually tightened her sway, appointing headmen or starchinas m every commune, and establishing several schools, as well as placing its representative at Betsho in a position to command some respect and obedience.

Towers and castles abound. Mestia has seventy towers forty to seventy feet high ; Ushkul about fifty and two castles. The towers, constructed for defence, are of untrimmed black slate, and are attached to houses built of the same material. Geography and Travel. 631 THE Sotomon IsLaAnDs.—The Solomons lie about five hundred miles east of New Guinea, and extend for six hundred miles north- west and southeast, between the meridians of 154° and 163° E longitude, and the parallels of 5° and 11° S. latitude. They were discovered and named by the Spaniard Mendana, in 1567. There are seven principal islands (Bougainville, Choiseul, Ysabel, Malayta, San Christoval, Guadalcanar, New Georgia) and several smaller ones. The total area of the group is estimated by Mr. ©. Woodford, who has recently returned from a lengthened residence among them, at 15,000 square miles, bnt they may still be con- sidered as to a great extent unknown. Dr. Guppy, who has recently written a valuable work entitled “The Solomon Islands; their ology, general Features, and suitability for Colonization ” was. attached to a man-of-war, but Mr, Woodford resided among the natives, engaged in collecting birds, mammals, ete., and was thus exposed to many dangers among a people who are given to head- hunting and cannibalism. The island of Savo was an active voleand when discovered in 1567, and at the present time has hot springs, which also occur upon Simbo and Vella Lavella, while Kulamb- angara is an extinct volcano. There is an active volcano near the centre of Bougainville. On this island, which is the largest and most northerly of the group, the mountains rise to a height of 10,000 eet, on Guadalcanar to 8,000 feet, and on the other large islands to from three to five thousand feet. The islands are mostly clothed with dense tropical forest from the coast to the mountain taps. Records kept by traders at Ugi and Santa Anna show that the annual rainfall is from 100 to 150 inches per annum. Mr. Wood- ford stayed awhile upon the islands of Alu, Fauro, New Georgia and Guadalcanar, on the last of which he lived half a year. Here he explored the rivers Aola and Kobua, and got a bearing of the the females are invested in a series of superposed fringes.

These laying-grounds are fenced off into small divisions for various owners. In New Georgia and the adjacent smaller islands the passion for head-hunting is such that no canoe can be launched without a head being obtained. The chief hunting grounds are the large islands of Choiseul and Ysabel, which have been nearly de- populated by the practice. i GODWIN-AUSTEN PEAK.—The second highest mountain known to exist on the earth’s surface is as yet unnamed, unless the letters K ?, by which it was characterized by the surveyors who discove and fixed its position nearly thirty years ago, can be called a name. Attention to this unnamed and unknown condition of the second mightiest elevation of the world, 28,250 feet above the sea- level, was called through the reading of Lieutenant Younghusband’s account of his adventurous passage over the Mustakh Pass on is way from China to India. General J. T.Walker (late Surveyor- General of India), has proposed that the peak be named Godwin- Austen, after the first surveyor of the Mustakh ranges and glaciers, and the proposition received the assent of the meeting of the Royal ‘Geographical Society. A route practicable for road or rail has been found from Assam to Upper Burma, across a belt of dense tree jungle and mounta, which lies between the last British station in Assam and the summit of the Patkoi range. Arrica.—THE CamEroons.—M. Valdau, a Swedish colonist of the Cameroons, explored the northern slopes of the range in the early part of 1887, and found that the main chain does not extend as far as 4°30’ N. Latitude, since the highest point attained by him, about 4°28’ N. Latitude, only measured 2,850 feet. M. Knut- son, another Swede, in July last discovered the mouth of the rivet Memeh, which had previously been supposed either to be a tributary of the Rio del Rey, or of the Rumbi. Its embouchure is a little to the south of that of the Rumbi. M. Knutson ascended the rive which he found to be navigable for about thirty miles, as far as the Diiben Falls, 100 feet in height. ce SENEGAMBIA.—French explorers and surveyors have been busy in Senegambia. The country of Bondu, hitherto known only from the itineraries of Mungo Park and others, has been thorou hly surveyed by M. Fortin and Leforte ; and the district of Bambus which two years ago was the least known part of French Sudan, Geography and Travel. 633 has been completely surveyed by a large party of officers. This region occupies the territory between the Faleme, Senegal, Bafing, and the country of Konkadugu, but its population is only 20,000. The divide between the Senegal and the Gambia was explored by the military columns which operated against the Marabout Mah- madu Lamine. It consists of undulating plains of small elevation, with stony patches at intervals, and contains five small confederated states, with a population of about 13,000. South of Bambuk Captain Oberdorf has explored the Upper Gambia to 12° S. Latitude, and also the upper courses of the Faleme and the Bafing, two important tributaries of the Senegal. Existing maps, especially as regards the Faleme, will have to be considerably altered. This river does not rise in the plateau of Timbo, but in the Koy Moun- tains. The Tene, hitherto regarded as the upper course of the Faleme, is an affluent of the Bafing. The large tributaries of the Senegal have some fine open reaches, but their navigability is pre- vented by frequent rapids and falls. Captain Oberdorf concluded treaties with all the tribes visited, save those of Koy. Lieutenant Reichemberg visited Konkadugu, Bafe, Solu, and the left bank of the Bafing. Valuable auriferous bearings are reported from the first of these districts. Captain Peroz, whose mission was directed southeast of that of Captain Oberdorf, surveyed the valley of the Milo as far as Bissandugu, and also the Bure and Upper Bafing, but the chief result of his efforts was the conclusion of a treaty with Almany Samory, by means of which the French possessions are extended to the banks of the N iger and the Tankisso, and the rench protectorate to the confines of Liberia. Lieutenant Quin- quandon and Dr, Tautain, who were sent to visit Great Beledugu and the left bank of the Niger, visited Murdia, Gumba, Segala, and Sokoto, and report that the soil becomes less and less fertile oiee the northeast, where the country is analogous to Southern geria. Evropr.—Turer Days on THE SUMMIT OF Mont BLANC.— A party of French meteorologists spent three days of July, 1887, on the summit of Mont Blanc. They were accompanied in the ascent y twenty-four bearers, of whom all but two deposited their burdens upon the summit and immediately departed. In the ascent of the last hill, M. M. Vallot and Richard were attacked by mountain sickness and did not recover for several hours. In a small in- dentation between the dome of the summit and the ridge by which it Is reached the observers pitched theirtent. During the first night - Vallot attempted to fix the instruments, but was driven back by the wind and snow. During the next day he was more Successful. While on the summit the health of the party was not het 4 good, yet numerous physiological and meteorological observa- ‘ons were made. On July 30th a terrible thunder storm raged around them for several hours. ; 634 General Notes. THE GERMAN PopuLation.—M. Ch. Grad (Revue Scientifique, April 14th, 1888), gives the number of German-speaking people within Germany itself at 41,512,000, and the entire German-speak- ing population of Europe at 60,000,000. To make up this total we have 8,000,000 in Austro-Hungary, 1,900,000 Swiss, 860,000 Russian Germans (625,000 of whom are Jews), 4,270,000 Hollan- ders and Luxemburgers, 3,400,000 Flemings (300,000 of whom are in France), and 30,000 Germans resident in Belgium. The number of Germans in Europe has doubled since 1820, in spite of the emigration. The 3,722,000 non-German speaking individuals enumerated at the last census by no means represents the actual extent of the Slavic element, since the whole course of the history in the provinces east of the Elbe has been one of Germanization of an originally Slavic population. THORODDSEN’S EXPLORATIONS IN IcELAND.—M. Thoroddsen has contributed to Petermann’s Mitteilungen an account of his exploration of the northwestern peninsula of Iceland in 1886. This part of Iceland forms a table land, averaging rather more than 2,000 feet in height and broken up by fjords the sides of which are almost perpendicular. Nearly every fjord has distinct terraces representing ancient coast lines, now high above the sea. nks of shells identical with those now living in the sea, and skeletons of wha! and walrus have been discovered in these terraces. The A Discovery IN THE ARCTIC Ocran,—According to the organ of the Geographical Society of Stockholm, Captain Johanne- sen last summer su in reaching an island, situated to the east of Spitzbergen, in 80°10 N. Latitude, and 32°3’ E. Longitude. This island is a table-land rising to 2,100 feet, and is su to be the same as Hvide O, seen by Captain Kjeldsen, and also by Captain Sorensen on August 28th, 1884. This discovery confirms the existence of an archipelago extending from Spitzbergen to Franz Josef Land, preventing the ice from cia into the ts Sea, and thus having a great influence over the climate Europe. Geslogy and Paleontology. 635 GEOLOGY AND PALAZONTOLOGY. RoMANOVSKY’s MATERIALEN ZUR GEOLOGIE VON TURKES- TAN.—Scattered notes of the geology of Central Asia have from time to time been given in these pages, but M. Emm. de Margerie’s Compte-rendu de publications relatives à la Géologie de l Asie et de l Amérique now gives us the opportunity to give a fuller account. MM. Mushketoff and Romanovsky, after having explored with great thoroughness the possessions of Russia in Central Asia, have published a part of their results. The first volume of M. Mush- ketoff’s orographical and geological description of Turkestan appeared in 1886, while the first number of M. Romanovsky’s Materialen zur Geologie von Turkestan was issued in 1880. M. Mushketoff considers the natural limits of Turkestan to be as follows: the Mougodjar mountains and the plateau of Ust-Urt to the west; the Tsungarian Ala-tau, the chains of the Tian-shan and the Pamir to the east; the Kopet-dagh and the mountains of Kho- rassan to the south ; and the Tarbatagai, Zenghis-tau and the water- shed between the Aral and the affluents of the Irtish to the north. The space comprised within these boundaries consists of two unequal parts, separated by the crest of the Kara-tau: the northern part, about one-third of the total area, corresponds to the basins of Lake Balkash and of other smaller lakes, while the larger »uthern part forms the Turan or basin of the Aral. The latter is divided by the Nura-tau into two portions: the basins of the Syr-daria and of the Amu-daria, the latter twice the size of the former. The reliefs of Turkestan pass from the N. E.—S. W. direction to that of N. W.—S. E. by insensible gradations, so that they form bundles of folds having their convexity turned towards the south, as in the chains of northern India. There are three principal groups of folds, the Tarbatagai, the summits of which do not pass 2500 metres ; the Tian-shan in the centre, with summits reaching £ metres, and even 7300; and in the south the Pamir with a central crest reaching 4500 to 5000 metres, and with some summits of even 8000. Notwithstanding the diversity of the rocks that enter into its constitution, the Turanian basin presents a monotonous and but slightly varied geological structure, since Cretaceous, Tertiary, and post-tertiary deposits cover ninety-five per cent. of the surface, the older formations appearing only as masses here and there piere- ing the uniform mantle of modern sediments. Above the Palæo- Zoic rocks, with a very noticeable uncomformity, lies a series of deposits with fossil plants, evidently a prolongation of the plant- ring series of Afghanistan, and of the Gondwana group of Hin- dostan, During the Jurassic period the Turan formed a great island, extending far to the east, where scattered lagoons received 636 General Notes, sediments of small thickness ; these sediments accumulated along the southern coast of the emerged land, but, as in Afghanistan, cover only a comparatively small area. Beds of lignite are abun- dant in the lower parts of the Trias-jura, as, for example, on the flanks of the Kara-tau and all around the Fergana basin, and in the absence of the true coal-measures, may prove of economical importance. The Jurassic is conformably covered by the Creta- ceous and Tertiary beds, which reach a thickness of 650 metres in Fergana, and even 1600 in Hissar. These two series are so inti- mately linked that it is impossible to fix a precise line of demarca- tion between them, and both alike have been affected by dislocations which are well-marked near the mountains, but die out in the centre. The Cretaceous series comprehends very varied rocks, those of the plains differing much from those of the Tian-shan, where they consist chiefly of marls and limestones, the latter often shelly, but becoming oolitic and compact more to the east; the marls often enclose gypsum. It is in Fergana that the Cretaceous ‘presents the greatest diversity of faces, but as fossils are rare and in poor condition, it is difficult to separate the series into stages. GENERAL.—THE GEOLOGICAL STRUCTURE OF AFGHANISTAN, —M. Griesbach, Geologist of the Afghan Boundary Commission, has at various times published in the Records of the Geological Survey of India preliminary notes upon the geological structure of those portions of Afghanistan visited by him. These facts have been brought together by M. de Margerie in his Compte-rendu de Publications relatives à la Géologie del Asie et de P Amérique, in such a manner as to give what appears a tolerably clear picture of the geo- logical structure of this mountainous country. The principal crest of Afghanistan is formed by the Hindu-Kush and the Koh-i- Baba, the latter of which is continued into Persia, by chains running 10 the northwest. Although the greater part of the country 18 a8 yet geologically unexplored, the researches of M. Griesbach are suffi- cient to afford a good index to the character of the remainder. It thus appears that the palæozoic and older mesozoic rocks only come to the surface on the line of the main axis, the rest of the country being occupied mainly by cretaceous beds, often unconformable to the older mesozoic beds upon which they repose. Extensive sur- faces in the north and west are covered by tertiary deposits. p region between the main chain of Afghanistan and the next noe important series of elevations, viz., that which runs llel pa Indus, is occupied by a number of anticlinal folds, crowded together in the region of Cabul, but spreading outwards approach the frontier of Persia. Most of t Geology and Paleontology. 637 come more accentuated. North of the main axis lie a series of par- allel folds, narrow and lofty near the centre, but gradually spread- ing as they recede from it until they become broad and low undu- lations. ‘The geological structure of Persia seems to be a continu- ation of that of Afghanistan. The oldest fossiliferous deposits as yet known belong to the Carboniferous system. Wherever exam- ined, the Carboniferous outcrops are, like all the great bands ex- tending from Armenia to the Himalaya, of marine origin. Above the Carboniferous beds lie a number of conformable deposits com- posed of marine beds alternating with littoral and fresh-water lay- ers enclosing lignite and abundant remains of terrestrial plants. The exact classification of these beds has not yet been attempted, but they are surmounted conformably by undoubted Neocomian deposits, and their lower schistose portion is regarded by M. Gries- ach as representing the Permian and Lower Trias; while Jurassic fossils have been discovered in the upper part. Great eruptive rial seems to have characterized the end of this series of litto- ra x molluses found in it. The Niagara shales themselves can, upon ` evidence, yet Homalonatus reaches its maximum size after a Cælosteus feroz is the name given by Prof. Newbe ] s y Prof. Newberry to a large oa of fish, apparently allied to Dendrodus and Rhizodus, ot ch the Jaws, teeth and bones were discovered in the Lower 638 General Notes. Carboniferous Limestone at Alton, Ill. The lower jaw is about a foot long, an inch and a half wide in front, and widens to four inches behind. It is marked on the upper margin by a series of thin shell of bone, enclosing a large area, whi occupied by cartilage. The dentary differs from that of Rhizodus in being entire. Titanichthys clarkii Newb., discovered by Dr. W. Clark near rea, O., exceeds in size even the T. agassizii of which drawings were exhibited at the meeting of the American Association at Mon- treal, 1882. The broadly triangular cranium measures five feet or more between the posterior lateral angles. It is concave behind, and the central part of the arch is marked by a broad depression as in Dinichthys. The condyle of the. post-temporal bone is hori- zontal and broad, and is clasped in a furrow at the angle of the cranium. The post-temporals are a foot and a half wide, and, as in Dinichthys, are overlapped by the clavicles below and by the dorso-median plate above. This plate is sub-circular, and has a long, slender, furrowed process projecting backward and down- ward. The sub-orbital bones are eighteen inches long, the man- dibles three feet. The posterior end of the mandible is spatu- - late, six inches wide, and turned upward ; the anterior end is turn up like a sled-runner, and is excavated by a deep furrow some what as in T. agassizii, but the whole jaw is much heavier and broader. The under side of the body was protected by a triangu- lar plate three feet long and nearly as broad, having a deep sinus posteriorly and a rounded projecting angle near the middle of either side. Mesozorc.—Mr. A. S. Woodward (Quart. Jour. Geol. Boc., Mar; 1888) describes Semionotus capensis and Cleithrolepis extont, bo from the Stormberg Beds (Early Mesozoic) of the Orange F pa State. The only species of Cleithrolepis before described, 18 f granulatus, from the supposed Triassic Hawkesbury Beds w New South Wales. The South African specimens afford sufficien data to prove that the genus must be placed with the Dapediidæ. A. Weithofer describes in the Annals of the Naturhist pyre Hofmuseum of Vienna, a new Dicynodont (Dicynodon sunocep is from the Karroo formation of South Africa. The gran unfortunately only an imperfect half of the cranium, lacking the lower jaw, yet it offers characters which distinguish it from hly species described by Owen. ‘The parietal region 15 Very. ve developed, rising eleven centimetres, or more, above the lme Geology and Paleontology. 639 necting the mastoid and the frontal, whereas in D. pardiceps Owen it only rises 5.5 cm. over the same level. The frontals are less developed than in D. leonticeps, the orbits are deeply sunk, and the nasal openings are placed far forward, so that it is one of the most peculiar representatives of the group. The entire occipi- tal region and the bones of the under side are wanting. : i strata belong to six genera, viz., Diplurus (1 sp.), Ischypterus (18 sp.), Catopterus (5 sp.), Ptycho- the English Lias. All the species are distinct from any known in the Old World, but a species of Ptycholepsis allied to ours is found in the Lias of Boll, Wurtemburg, and a species of Dictyopyge has been described from the Keuper of Germany. Catopterus seems to be distinct from any genus of fossil fishes found in the Old World, but Ischyp- terus is very near to Semionotus Ag., which is represented by Geo. F. Becker (Bull. Cal. Acad. Sei.) replies to Messrs. Hague and Iddings’ criticisms upon his conclusions respecting the pyrox- enie rocks of Washoe. The former geologist sees in these rocks evidences of two separate eruptions, and therefore divides them nto diabase and andesite, while the latter geologists consider both 640 General Notes. of these masses as substantially a single Tertiary eruption. Mr. Becker claims to have found additional reasons for maintaining the existence of diabase, and also for dividing the pyroxene andesite into two distinct outflows, separated by a long interval of time. At Steamboat Springs, about six miles from Virginia City, occurs an extensive series of sedimentary beds, nearly vertical, with a strike following the general direction of the Sierra. Andesites and basalts have broken through and overlie these beds, which are with- out trace of fossils, and are evidently pre-tertiary. Indeed, they appear to be as old as the rocks determined as Jura-Trias by the geologists of the fortieth parallel. These sedimentary beds contain pebbles of the exact character, both physically and mineralogically, with the east wall of the Comstock lode, determined by Becker as porphyritic diabase. The presence of these pebbles in beds of pre- tertiary age proves that there must be real pre-tertiary diabase somewhere in the neighborhood of Mt. Davidson. This locality is substantially in the same district as the Comstock lode, and, accord- ing to Mr. Becker’s investigation of the faulting action on the Com- stock, formerly received the drainage from the diabase area at Virginia. In the thirty-fourth part of Palewontographica, E. Holzapfel describes the molluses of the Cretaceous of Aachen, prefacing his account with descriptions of the strata and lists of the species con- tained in each. Dr. Rust (Paleontographica, Band xxxiv.) adds an importi contribution, illustrated with eight plates, to the knowledge of Radiolaria of the Cretaceous. Whilst in the Jura the oldest en bed in Dr. Rusts monograph, 59 are found in the Neocomian, 109 in the Gault, and only six in the upper stages of the system. Cæxozorc.—Prof. J'Prestwich (Quart. Jour.

The sands and marls of Heers Geology and Paleontology. 641 gium) are usually considered as a separate horizon, but Prof. Prest- wich points out that there is nothing in their molluscan fauna to warrant them as older than the Landenian, while the presence of sixty-two plants, all but one new and peculiar to the locality, may be simply due to the proximity of land. He objects also to the correlation of the Sables de Bracheux with the Lower Landenian and Thanet Sands, pointing that out of the eighty-two species of mollusea found in the Bracheux Sands only six seem to be common to the Thanet Sands and five to the Lower Landenian, while ten are found in the Woolwich beds. A table gives Prof. Prestwich’s views upon these and other points in the correlation of these impor- tant beds of the London, Belgian and Parisian basins. A. Weithofer has recently described several species of bats from the phosphorites of the central plateau of France, including Pseu- dorhinolophus, sp., Alastor heliophigas., nov. gen. and sp., Rhino- lophus dubius, V espertiliavus, sp., Taphozous, sp., Neoremantis adi- chaster, nov. gen. and sp.

THE FLORA or PALESTINE.—A. general opinion seems to prevail, even among those who have visited the country, that though flowers are abundant in Palestine, especially during and immediately succeeding the rainy season, yet the number of species is remarkably small. This idea as to the paucity of species is scarcely correct. The multiplicity of species, and the large variety of peculiar forms are, in fact, in many cases, noticeable features of the flora. As an example, I may state that I have collected, in the imme- diate vicinity of Jerusalem, eleven species of Geranium, including the G. tuberosum, that very distinct species with tuberous root. In this group, as in most others, the differentiation of the species is remarkably pronounced, being displayed not only in the form, color, number, furnishing and disposition of the blossoms, but also, being exhibited in the great variation of the leaf, and even some- times, as in the case of the species mentioned, passing into the character of the root. i I have had my attention attracted by the great number of cruci- ferous plants, as also those of a prickly or thorny nature. Indeed, genera whose species in other countries are usually smooth and unarmed, are here represented by species having prickly, spinous, or thorny appendages. It may be considered significant that im this land, where the great event (the central thought of Christianity) occurred, the plants should be found so frequently bearing the cross and wearing the thorns. . The number of garden plants which here grow wild has been commented on. To-day, I found on the rocky hills around Jeru- salem the Narcissus and the Scarlet Anemone, Cyclamens, and the little blue-gray Iris, all in blossom. The Narcissus as we Almond had been in flower for more than two weeks, and the Crocus and Orange for months ; the fruit of the latter (confined to gardens) having been ripe since November. The Asphodels were pushing up their long stalks, heavy with buds, from among their spear-like leaves; and the purple Bugloss (Echium violaceum) hung from the cliffs. The very rocks seemed breaking out into blossom and praise. i In northern Palestine, in the months of March and April, 0g the effect of the rainy season has been felt, the bursting of the lan into flower is a sight never to be forgotten.

A MINIATURE TuMBLE-wEED.—On the great plains of Nebraska, from the altitude of two thousand five hundred to three thousand feet above sea-level, to and throughout the Rocky Mountain region there grows the very pretty little aster-like plant known as Town- sendia sericea Hook. It blooms in early spring, and its pretty, almost sessile, heads of numerous flowers nearly cover the plant itself, so that one sees little more than a compound rosette of yellow and delicate pink close upon the ground. After blossoming, the bracts of the involucer remain for a consider- able time widely opened, but when the achenes are ripe the involucer ” closes and forces out the mass of achenes, with their abundant long, white pappus and effete corolla tubes. This expulsion was observed in to take place, in one instance, in a plant grown in my laboratory with such force as to suddenly throw the mass of achenes and pap- pus out free from the involucer. I suppose that the spreading of the pappus has also much to do with freeing the achenial mass from the involucers. Possibly the pappus and involucers act together. a The achenes are pretty well covered with long twisted and bent yan ” hairs, asis common in this and many allied genera.’ sshown b ie, in hi ron “ Achenial Hairs and Fibres of Diaan gy meae ren eeta Vol. XVII., p. 81; and also “ Achenial Hairs of Townsendia.” Ibid., p. 1102. General Notes. The extremities of the hairs are recurved into double hooks, as shown in the accompanying cut (Fig. 1). The body of the hair (as shown by Macloskie) is composed of two parallel, greatly- elongated cells, each of which is recurved, thus forming the double hook. In some instances I have observed septa in one or other of the cells, although for the most part they are wanting. The hairs upon each achene become interwoven with those of neighboring achenes, and, upon drying and twisting, they firmly bind together all the achenes of each head. The spreading pappus forces the mass to take an ellipsoid form as soon as it has escaped from the invo- lucer (as shown in Fig. 2), Lying now upon the surface of the plant, and entirely freed from the embrace of the involucer, the light mass 1s ready to begin its career as a min- iature “ tumble-weed.” After a few ME NSS os sze TOlls it loses most of the effet ecorolla Fig 2. tubes and tumbles lightly along upon the points of its spreading pappus. The jarring gradually separates the tumbling ball; but even when it breaks in two, each part rounds up again by the wide spreading of the pappus and rolls on again before the brisk breeze of the plains, dropping here and there an achene with its hidden seed, just as the great tumble-weeds, Amaranthus, Cycloloma, Corispermum, etc., do in their larger way.— Charles E. Bessey. Unperwoop’s FERNS AND THEIR ALLIES.'—This little book, the first and second editions of which were noted in the NATURAL- IST at the time of their appearance, has been entirely re-written ; and while the general plan of the former editions has not been materially modified, the details have undergone very considerable anges. e present edition contains thirty-four pages more 0 matter than the last, and this increase is divided between the gen- eral matter (which gains nineteen pages) and the systematic portion, which is increased fifteen pages. This increase in the number of pages is due to the new matter introduced in the general part, consisting mainly of excellent ref- erences to the literature of the subject, and in the systematic part to a considerable increase in the number of species. The glossary 15 also much increased in volume and value. The book is a most useful and handy one, and will enable the student of the Pteridophytes to obtain an excellent idea of their structure and classification. ‘ Our Native Ferns and Their Allies, with Synoptical Descriptions = the American Pteridophyta north of Mexico.

The Bunocephalids (= Aspredinidz) usually associated with the Loricariide have no skeietal affinities with that family, being much more nearly related to the Siluridæ. The genus Cetopsis, as before stated, is more closely related to the species of Pygidiidee (—Trichomycteridze) than to the species of Doradine, with which it has usually been associated. The genera Heptapterus and Nannoglaris, on the contrary, are closely related to some of the species of Giinther’s Pimelodus, and have no real affinity with the Pygidiide.

ENTOMOLOGY: SOME OBSERVATIONS ON THE MENTAL POWERS OF SPIDERS.— Under this title an important memoire is published by George W. and Elizabeth G. Peckham,’ in which these observers detail numer- ous experiments upon the senses and mental powers of spiders. The following extracts will serve to indicate the scope of these experi- ments, and some of the conclusions deduced from them. “Our experiments on the senses of smell in spiders extended over two summers. Many of them were performed by each of us sepa- rately, that we might detect the mistakes of the other. Our usual plan was to hold a slender glass rod, eight inches in length, in such a position that one end closely approached the spider, noting what effect, if any, was produced, and then to dip it into whatever scent we were using, hold it in the same position, and again note the effect. We tested them in this way while at rest in the web, while stalking their prey, while feigning death, and under various other conditions. ; “The scents used were essential oils, cologne, and seteral kinds of perfumes. Acetic acid, vinegar, and like materials were avoided on account of their irritating action upon the integument. o sum up our work on the sense of smell, we made, in all, two hundred and twenty experiments. We found three species (Argyroepeira hortorum, Dolomedes tenebrosus, and Herpyllus eccle- siasticus) that did not respond to the tests. In all other cases 1t was evident that the scent was perceived by the spiders. This they showed in different ways,—by various movements of the legs, palpi and abdomen, by shaking their webs, by running away, by seizing the rod and binding it up with web as they would an insect, and in case of the Attidæ, by approaching the rod with the first legs and palpi held erect; but whether in the way of attacking 1t, or, as It sometimes seemed, because the smell was pleasant to them, 1t 18 impossible to say.” : e most successful experiments upon the sense of hearing were conducted with tuning-forks. “These show that certain spiders indicate that they hear a vibrating tuning-fork by characteristic movements of the legs. Another set of spiders, however, mani- — fest their perception of the sound in a different way. With th ! This de } ornell Univer- Best nem N. Yo ré edited by Prof. J. H.

Entomology. 655 the approach of a vibrating fork seemed to cause a greater alarm, making them drop from the web and keep out of sight for a longer or shorter time. However, after one of these spiders had been subjected to the experiment several times, it would, instead of drop- ping, raise its legs in the manner described above. “A few experiments were made to determine where the organ of hearing was located, but we can offer nothing positive on this ques- tion. It seems probable that the auditory apparatus is but little specialized, Possibly it is spread over a considerable portion of the epidermis, . She at once went to the eggs and touched them with her legs. She then left them, to improve her “Se their cocoons for twenty-four hours; yet these spiders, although they do not carry the egg-sack around with them, remain near it for from fifteen to twenty days.” bearing on the sense of sight, they state: “We have fre- quently, while feeding our captives, seen them stalk their prey at # distance of five inches; and we have repeatedly held the active Jumping-spider, Astia vittata, on one finger, and allowed it to jump on to a finger of the other hand, gradually increasing the distance vP to eight inches. As the distance increased the spider paused ar a before springing, gathering its legs together to make a good “We have twice seen a male of this species chasing a female "pon a table covered with jars, books and boxes.. The female a leap rapidly from one object to another, or would dart over ti edge of a book or a box so as to be out of sight. In this posi- ae: she would remain quiet for a few minutes, and then, creeping the edge, would peer over to see if the male were still pursuing 656 General Notes. her. If he happened not to be hidden she would seem to see him, even when ten or twelve inches away, and would quickly draw back ; but in case he was hidden behind some object, she would hurry off, seeming to think she had a chance to escape. “ The male, in the meantime, frequently lost sight of the female. He would then mount to the top of the box or jar upon which he found himself, and, raising his head, would take a comprehensive view of the surrounding objects. Here he would remain until he caught sight of the female,—which he often did at a distance of at least ten inches,—when he would at once leap rapidly after her. “The ocelli of some spiders, then, enable them to see objects at a distance of at least ten inches.” In order to determine whether spiders have a color sense or not, experiments were tried upon species that were found during the ay, running among dead leaves, or hiding under stones or wood. Cages were constructed, each consisting in part of blue, green, yel- low and red glass. Spiders were placed in these cages, and the color of the glass beneath which they retreated and remained was noted. The relative positions of the colors were varied on the dif- ferent experiments. It was found that in two hundred and thirty- seven trials the spiders chose the red one hundred and eighty-one times, the yellow thirty-two, the blue eleven, and the green thir- teen. These experiments seem to be conclusive as to the existence of a color sense in certain spiders. We have not space to quote the results of experiments pay feigning death by spiders, nor to repeat the accounts of mistakes 0 spiders. MEETING OF THE ENTOMOLOGICAL CLUB OF THE A. A.

He records a singular periodicity in the breeding habits of this animal. They deposit several crops of ova during a single season (April), and therefore produce several broods of young which become successively attached to the arms of the parent animals. The development of Comatula covers a period of seven days. On the first day oviposition, segmentation, and the formation of the blastula takes place; on the second day the gas- trula and blastopore is formed; on the third day the enterocoel, intestine, water-vascular ring, etc., is formed. On the fourth the development of the visceral mass is completed ; on the fifth day there occurs the displacement or rotation of the visceral mass, con- stituting a sort of metamorphosis ; on the sixth day the skeleton is formed, and on the seventh hatching occurs. The following general conclusions are submitted by the author at the close of the memoir — Fundamental Homologies. The first and one of the most important results which have been established by the foregoing studies is the proof of the homology between the peduncle of the larva of Comatula and the preoral lobe of other Echinoderms, between the calyx of the larve of Comatula and the body, properly so-called, of the larve of other Echinoderms. But, aside from this important homology, the development. of Comatula differs in two important respects from that of other Echinoderms. i First difference. —In the ordinary Echinoderm-larva (Asterias body, direct] “fo the latter is found to be inserted at one edge of the preoral uncle), it assumes a terminal position.

Genève- 658 General Notes. this difference, there is an irregular and abnormal mode of devel- opment which does not present it at all, and which, under the con- dition of the primitive relations of the calyx and of the peduncle, presents the same disposition as in all other Echinoderms; that is to say, that in which the calyx is inserted at one side. We are therefore led to conclude that the difference here noted is not a fundamental one, but that it constitutes a simple alteration of the primitive plan common to all other Echinoderms, resulting from fixation and which disappeared immediately after that fixation ceased to occur. Second difference. — In the ordinary Echinoderm larva (Asterias, Echinus), the two peritoneal vesicles maintain their primitive situa- tions, the one at the right and the other at the left, the dorsal face (aboral) of the future Echinoderm being formed at the expense of the portion of the larva which answers to the left peritoneal vesicle. Asa result there is a singular discordance between the two faces of the adult and the two faces of the larva, which has been noted by numerous observers, and which consists in this, that the right side of the larva becomes the dorsal face, and the left side of the larva the ventral face of the adult, so that the now outline Echinoderm is found to be placed in a transverse and a symmetri- cal position in relation to the preoral lobe of the larva. In Coma- tula, we have seen, on the contrary, that the ventral and dorsal faces of the larva correspond respectively to the ventral and dorsal faces of the adult in such a manner that the outlined adult (or calyx, in other words), instead of being placed transversely to the peduncle, occupies a symmetrical and regular position in relation to the latter. ; e have seen, however, that there is not such a discordance between the positions of the dorsal and ventral aspects of the larva and adult Comatula, and that the two peritoneal sacs here, instead of maintaining their primitive position as in other Echinoderms at the right and left of the embryo, set out on the fifth day, in Coma- tula, to change their positions, the right sac becoming dorsal, an the left one ventral. Now, if we admit that the formation of the dorsal and ventral faces are subordinated to the position of or peritoneal sacs, we arrive at the conclusion that the displacement 0 the peritoneal sacs as described above, is a sufficient explanation of the differences noted at the outset. : which Barrois, 25 compared with those of Busch, Thompson, Metschnikoff, Gotte and sible of Embryology. 659 published, and on that account may be commended to the attention of students. N THE DEVELOPMENT OF THE COMMOM STURGEON. — Hav- ing been requested by the United States Fish Commissioner, Marshall MeDonald, to undertake the investigation of the stur- geon (Acipenser sturio), I repaired to Delaware City, Delaware, with that object in view. On the 15th of May mature eggs were found in a large female of that species, which was brought in to Mr. Anderson’s float. Fortunately a ripe male was encountered at the same time, also in a living condition, from which sufficient milt was obtained for the purpose of fertilizing the eggs. The eggs were quite free in the abdominal cavity, and they ran out in somewhat the way shot would pour out of a rent in a bag, as soon as the abdomen was cut open. The germinal disk was already formed ; in fact investigation disclosed the fact that the germinal disk, or area, is developed before the ovum leaves the follicle in - which it is matured. Two sorts of ova were found in different individuals. In some the eggs were brownish gray or olive, in other females the eggs were very much darker and contained far more pigment. In all of them, however, the germinal area was clearly defined at one side often with a distinct round dark spot marking its centre, with a paler ring surrounding the central dark area. External to the pale ring there was a distinct dark ring, followed on its external margin by anarrow pale band, from whence the color over the vegetative pole or yolk became uniform. In the darker variety of eggs some of these rings were not so distinct. uring the first hours of development but slight external changes were observed in the form of the germinal area, but by the second day this area had become distinctly oval; the central dark patch was oval and the marginal pigmented ring also oval. The eggs had also changed shape ; instead of remaining globular as they were at first, they assumed a slightly oval shape, the long axis of the oval lying parallel to the long axis of the now elongated germinal area. In the course of the third day the oval germinal area ha given place to one of somewhat different configuration. Instead of being oval, the germinal area now became decidedly more elongated and rounded at either end, and constricted at the middle, somewhat like the y of a violin. The medullary groove now me visible, and on the third day was distinctly apparent. On the fourth day the head, body and tail of the embryo had been differ- entiated so far as to project distinctly above the level of the oval yolk sack, the tail was in fact developing as a free, flat lobe. The heart could be seen pulsating within the thin-walled pericardiac 660 General Notes. dark, while the pigment gradually faded out along the sides of the y where the walls of the latter were continued over the yolk sack, leaving the latter quite light beneath, or of a dirty yellow tint. The eggs of the common sturgeon are very adhesive and must be transferred to trays formed of wire gauze or thin cotton cloth tacked to wooden frames, as soon after fertilization as possible, and spread out in a single layer. If this is not done the eggs will form large masses through which fresh oxygenated water cannot penetrate, and, asa result, those in the centre of the masses will be asphyxiated, fail ‘to develop and become putrescent. The time occupied in handling them after fertilization should not be over twenty minutes. After two or three hours the eggs are firmly adherent to the wire cloth, thin muslin or cheese cloth, and the trays laden with eggs may be placed in running water without fear of detaching any of them, as their mucigen covering has by this time become quite coagulated and gelatinous, forming a coating over the zona radiata of irregular thickness. 1e zona proper is quite thin and some- what elastic, but easily broken, so that the eggs are rather delicate in character. There is no “breathing chamber” developed such as is found in the eggs of many Teleosts. The operator must carefully guard against the appearance of fungus.—John A. Ryder. ARCH ZOLOGY AND ANTHROPOLOGY. TOPINARD ON THE LATEST STEPS IN THE GENEALOGY OF Man.'—In this highly interesting lecture M. Topinard examines the evidence as to the later stages of human phylogeny, including those embraced in the series of placental Mammalia. He examines the opinions of previous writers on the subject, referring principally to Heckel, Vogt, Huxley, and Cope. He commences by a dis- cussion of the systematic relations of the contents of the order Quadrumana of modern authors, commencing with the lemurs He concludes that in spite of certain well-known peculiarities, the Lemuride must be included in the same order as the monkeys an man, in opposition to the view of Vogt. He then considers the question as to whether the Anthropoid apes should be arran with the Old World monkeys or with man, the former big opinion of Cuvier, Huxley, and Vogt; the latter that of ! Les derniéres Etages de la Genealogie de Homme. Lecon de Mars, 1888 ; Ecole d’ Anthropologie, Paris. Extract du Revue d’An pologie, May 1888. Archeology and Anthropology. 661 (unpublished) and of the writer of the present review.' He ecides in favor of the former. The probability of the origin of man directly from Anthropoid apes, as asserted by Heckel (monophyletic) and Vogt (polyphy- letic), or from Lemurs direct (the opinion advanced by Cope) is then discussed, and M. Topinard concludes that neither hypothesis can be maintained, in view of the structure of the posterior foot. He does not think that the ambulatory hind-foot of man could - have been derived from the prehensile hind-foot of the other quadrumana, and he therefore traces the origin of Homo to a common type in which the prehensile character of that foot has not yet been developed. This is the genus Phenacodus, or some alli form of the Condylarthra. He combats successfully the opinion that the monkeys and man have been derived from Ungulates, in the restricted sense in which that term has been used by some family Adapide the transition is very slight, provided that the latter pi the posterior foot in that family is not prehensile. The character of such importance that it need be much considered in 1 American Naturalist, 1885: ‘‘ Origin of the Fittest,” 1887. 662 General Notes. this connection. A very slight modification only of an ambulatory foot would make a prehensile one like that of the Simiide, an vice versa. In any case, whatever may have been the later stages in the phylogeny of Homo, we can regard such Lemurs as the Adapide as in the direct line from the Phenacodontide. There is a remarkable resemblance between man and the Anthro- poid apes in some parts of their skeleton in which they differ from the monkeys (Cercopithecidæ, Cebidee, Hapalide, and Lemuride). These characters seem to have been neglected by taxonomic writers. In the first place, the Anthropomorpha (Hominid and Simiide) agree in wanting anapophyses of the vertebre, while the families of monkeys and lemurs, above mentioned, agree with the Carniv- ora in possessing them. ‘This gives a distinctly different char- acter to the vertebral articulations in the two divisions.

In the Quadrumana, Schlosser has shown that in the Lemuride the inferior canine teeth are decurved and similar to the incisors, the teeth functioning as such, being the first pre-molars. In the other families of Quadrumana true canines are present in the lower jaw. From the foregoing considerations the phylogeny of these fami- lies will be as follows :— Hominide. Simiide.

On Frxine SECTIONS TO THE SLIDE.—Schiillibaum’s collodion fixative is found to be unreliable when used with the more elaborate micro-chemical reactions to which our advanced technique subjects the sections on the slide before mounting. Thus, sections fixed in this manner drop off in absolute alcohol. Mayer’s albumen fixative is absolutely reliable, and shou e used whenever sections are loosely coherent in their parts. One cannot obtain neat results with this, except by means of a very even and thin film, to secure which proceed as follows: A small drop of fixative is spread on the slide with the ball of the index finger. Excess of fixative is removed The stronger alcohols evaporate too rapidly. The sections pla on this film flatten out beautifully and can’be shoved about if alco- hol enough be present. When the film has evaporated thin the sections stick with great pertinacity. Superfluous alcohol a removed with filter-paper, and the slide must then be evaporat to dryness. The thermostat at 40° C., for 1 to 2 hours, 1s a useful in securing this result. The paraffin should never be gre to melt. It is removed by turpentine, as for other fixatives.

This was the form devised several years ago by Profes- sor Birge, of Madison, Wisconsin, and because for laboratory purposes comparatively few eggs are needed, and principally the earlier stages of development, we secure an efficient incubator and thermostat ata trifling cost. (Made of sheet-tin, the cost is not over five dollars. By modifying this form I have made a more elaborate, but more convenient, machine, which, having successfully stood the test of three seasons’ work at the Johns Hopkins Laboratory, I venture to describe. The “drum” was placed in a horizontal position, the tube a was added (making A superfluous). Apertures A and R and tubes a’ and ¢ were also added, as shown in the figures. The “drum ” was supported by a frame similar to what we get by taking off the top of a table and turning the rest upside down. The legs or uprights at each end were joined by a strip of sheet-iron 2 in. wide, forming a saddle-like belt. The forward end-strip, being cut six inches wide at its middle point, makes a fire-plate for the flame to play on. The point s tends to be the coolest; hence the position of the burner. The thermometer ¢ should mark the upper limit of the incubation temperature. sheet of tin is hung by wires, 80 that the Bunsen burner projects through a hole punched in it, and thus prevents reflection and loss’ of heat into the surrounding space. The whole structure should rest on a plate of zinc if the floor or table on which it stands is of wood. A coat of paint on the drum reduces radiation and consequent gas-consumption. The eggs are placed in pans 2 inches deep by 10 by 16. Each pan is made of two similar halves that slip one over the other, like the lid of a cardboard box. Thus either side may be up or down, and there- fore all the eggs in the pan (forty or more) are turned at once by turning the pan, and, besides, the marks on the eggs are easily inspected. For ordinary thermostat purposes, the trays can P replaced by shelves or drawers. The air circulates in part as indi- cated by the arrows, with such an arrangement of the pans as shown in the cut, but most of the air passes through the trays directly, and, thus, between the eggs. If a space be left above the water and the hole h be made to con- nect with an aspirator, on the one hand, and the tube A on the other, warm, moist air can be forced into the egg-chamber ; but the sponges 8, 8, are practically sufficient. I found by experience that even though the cyclindrical shape is the one giving greatest strength : (as well as ease of construction), that zine is not a good material for this machine to be made from, as it softens under warmth and yields gradually to the pressure. Therefore, if tin be departed from, -copper should be chosen ; but, of course, this will raise the priee.— J. Nelson. Scientific News. 667 SCIENTIFIC NEWS. —Dr. Roland Duer Irving, Professor of Geology and Miner- alogy at the University of Wisconsin, died at Madison on the 30th of May last. Professor Irving was in comparatively good health on the preceding Saturday, having taken a boat ride with his family on one of the lakes surrounding Madison. On Sunday morning about eight o’clock he was stricken with paralysis. Durin the day he was conscious, but could not be made to realize his serious condition. On Monday he was only half conscious, and from that time gradually passed into a deep stupor, which faded into death on Wednesday morning. Dr. Irving was the chief in charge of the Lake Superior Division of the United States Geological Survey. His most important work was the establishment of a great break in the geological continuity between the Laurentian and the Huronian systems, and (together with President Chamber- lin) the erection of a new system, the Keweenawan, between the Huronian and the Cambrian. At the time of his death he was engaged with Professor C. R. Van Hise in the preparation of a monograph on the iron-bearing rocks of the Penokee-Gogebic region. Professor Irving was a native of Staten Island, New York, and was a nephew of Washington Irving. He leaves a wife and three children, of the AMERICAN Naturaist for a time.

No. 260 OUR FRESH-WATER ALGZ.! BY EDWARD S. BURGESS. ‘WHat do you mean by the Fresh-water Alge? and what interest do you find in them? are the questions I find asked me. Go with me to the coast, if you would learn my answer. Notice the sea-weed growing along the shore; see the dark olives and browns shown in the rockweed, left dripping and slippery by the retiring tide; note the waving tufts of green laver and sheets of membrane-like sea-lettuce floating near the tide-mark, and watch the beautiful red mossy cushions of delicate growth washed in by the breaking wave. Ask of almost any dweller on the coast and he will say, “ People nowadays call them alge.” The longer you watch them the more attracted by their beauty you will become ; Soon you will begin to collect and mount them like other visitors to the shore. At first the most beautiful only will be collected ; then others that are less so, “simply for the variety,” ag you may apologize to yourself; finally you will end by determining to keep a specimen of every kind, whether beautiful or not. And now you approach the stand-point of science, for science sees interest in every representative of a race, whether that race be high or low; and finds in every plant a right to our regard in the fact of its inheri- tance of the mystery of life. But every summer must have its end, and so there will come the time of packing up the glowing specimens with their endless shades ‘Condensed from a lecture delivered at the United States National Museum, Washington, D.

With the return to the interior the desire rises to expression, “ Would that the inland waters contained such treasures as these mosses of the sea!” It is the old story, the wish is father to the thought, and the thought will perchance come to you, that perhaps they do; why should there not be mosses in the lake and river, brook and clear spring, as well as in the brine? and you resolve to look for yourself on your return, or you ask some one who knows to tell you if there are not also alge in the inland waters. “ Yes, certainly,” he replies, and you then inquire, “ Why is it then that I have never seen them?” to be reminded in turn that it is not the first time the eye has been awakened to perception of the beauties round its home by travels in a foreign land. Besides, the algæ of fresh-water are smaller and less conspicuous than those of the sea; many are microscopic, and many others are, when taken singly, but just visible to the naked eye. They are less varied in color as well, and so it has happened that many collectors know the sea mosses first, and if knowledge of the algx of fresh water comes at all, it comes as a derivative from the other. To compare the actual organs of the alga and the flowering plant, we remember that the flowering plant is adapted to land- conditions, securing nourishment from the air by its leaves an from the soil by its roots. The alga is adapted instead to water conditions and has no leaves nor roots for procuring nourishment, but absorbs through its general surface. The alga may or may not have root-like bodies (rhizoids), or a root-like base (a dise or hold- fast), but if present, these are simply to fix the plant in position. Presence of distinct stem and branches is optional with either. Most flowering-plants produce leaves ; most alga do not; those leaf-like bodies which are produced, as by the Sargassum or Gulf-weed, are called phylloids; these do not occur in the strictly fresh-water species, As its name indicates, the flowering-plant is to produce - flowers, and from them seeds containing an embryo of one or more seed-leaves (cotyledons), Alga produce no flowers and seeds, but instead, as a usual rule, spores. Their spores resemble seeds a8 appearance and in function, but contain no embryo and differ 12 details of development. ‘The alga is thus the less specialized, sii more simple, the lower in the scale of creation. Instead of delega ting the functions of plant-life to separate portions of itself as | Our Fresh- Water Alge. 671 organs, the alga often combines them all in a single cell or ultimate constituent. “In cases where the alga is composed of many cells the same principle often holds good, each cell being sufficient unto itself, uniting within its own small limits all the multifarious em- ployments or functions which make up the life-activity of its species, and therefore able to live equally well if by accident it becomes detached from its associated cells. Hard-working cells are these, for they have not yet learned the rudiments of the division of labor; cells of manifold activities certainly, and correspondingly hardy, self-dependent, and ever unsubdued. They live and replenish the earth unseen by man, till by effects or masses of individuals they move him to wonder, and, as in the middle ages, to ascribe their sudden-seeming presence to the wrath of heaven or the agencies of the black art or to the medium of alchemy. The present needs will not permit my entering into the subject of the scientific classification of the alge, but it may be of service to notice some of the principal groups for which common names are in use, According to habitat we may divide all alge into the marine and fresh-water divisions, including with the latter the erial species, surface-dwellers on moist earth, sand, rocks and trees. Recombining all the alge, they may be again divided according to coloring matter, contained, generally as a liquid, in their cells, classing them therefore as fhe red, olive and green alge, and fourthly as the Phycochroms, the last having as their characteristic a bluish cast seen in the green, ashen or grayish hue which pervades them. The red alge, so prized by collectors on the shore, are scantily represented in our inland waters ; the olive do not appear at all ; but the two other divisions find in fresh-water their chief representation. The green alge of the tide-marshes along the coast are very conspicuous, and of uncounted numbers, but of very few species comparatively ; those of fresh-water are probably still more abundant in individuals, certainly in species. The Phycochroms never reach as great a size as do members of each of the other sections ; they are, indeed, chiefly microscopic, as individuals, if not as Masses or colonies, Their cell-contents are also less highly organized. Their chief abode is in slowly running streams and quiet waters, They are the Cyanophyces of Goebel and of various authors since Nägeli, in 1849. They are remarkable for the pres- 672 Our Fresh- Water Alge. enceof a beautiful blue coloring matter, phycocyan ; and for the fact that no sexual modes of propagation have been discovered in them; nor, at least with rare exceptions, is there any evident nucleus, or central denser protoplasmic body, in their cells, such as is the rule elsewhere among plants. Multiplication in the algæ takes place in either of several ways; the most common is that of fission, as in the multiplication of cells in a flowering-plant, where each cell divides into two parts, each a perfect whole like its parent. The two parts gradually increase in size until they reach their full degree, then themselves divide again, — and soon. They may or may not remain attached to each other. Another mode of algal multiplication is by budding (gemmation), where the bud-like protrusion which grows into a new cell remains usually attached to its parent. A modification of this, prolification, consists of numbers of new cells arising from the side or end of the old, as if intended to become a separate individual, but often long adhering to the other, as if an attached child unwilling to remove from its parent. Some alge, as the Caulerpa, rely on this method for their chief mode of propagation, as do so many of the higher plants upon “ spreading by the root ” in place of production of seed. Another curious modification of budding is common in the red algee, the production of tetraspores, bodies which are formed by division of a cell into four equal parts, each of which becomes a spore, able to grow into a new plant, and thus analogous to the bulblets produced by tiger-lilies and some onions. Other algæ are reproduced by sexual methods, producing spores in some part of the process. Among the most remarkable of these are the zoospores, small seed-like bodies, usually soft and oval, sometimes spherical, tipped with one, two or more waving t (cilia), which lash the water and carry the spore onward in the current thus produced, sometimes with great velocity and sometime for several hours. The cilia finally fall off and the zoospore comes to rest ; and if favorable conditions have befallen it, it has effec a lodgement on some resisting substance, there to begin to lengthen, divide into cells, and grow into a new plant. During their m e stage these little spores seem like so many little green animalcu!es darting about ; so indeed they were long thought to be; and P names still perpetuates this idea, the word zoospore meanmg “ animal-spore.” Our Fresh- Water Alge. 673 Another kind of spore, motionless, unlike the preceding, the zygospore or “ yokespore,” is produced only as the result of two cells uniting and fusing their contents, the confined mass becoming the zygospore. This process of coalescence, known technically as conjugation, occurs in the beautiful Desmids, algæ so distinct as to form a group by themselves and therefore not now to be entered upon. The process also occurs in the Spirogyras and their relatives common in conspicuous green masses in still waters, each mass composed of long threads tangled together which shine with silky lustre when taken out of the water giving them their English name of silkweeds. These spores are smooth or spiny, often studded with knobs or branching thorns ; they have a thick, hard case, resisting the drouth of summer and the cold of winter, enabling them to await their proper time of growth in safety. The zoospores are liableto confusion with certain green infusoria ganimalcules, the zygospores with certain similar unicellular alge as species of Acanthococcus, now thought to have been often mistaken in this country for desmid zygospores. A very curious kind of reproduction is that of the Vaucheria and its allies, the production of “ oospores,” which resemble zygospores in their resting-period and in their hard, shell-like case, but differ in formation, And if with Goebel we include the Charas among the alge, we are presented by them with still another mode of reproduction, the formation of “ nucules ” or nutlets, dark or red, often strikingly handsome to the naked eye when abundant in their little clusters on the green feathery plant, each nucule surrounded by its little involucre and itself chased as if by chisel with a spiral line winding many times round it. ; But perhaps the most complicated of algal systems of reproduc- tion is that of the red algæ, to be observed in fresh water in the Batrachosperms, Lemaneas, ete. It may be called the cystocarpic system, its result being the formation of a fruit or cystocarp, filled with spores, often reminding one of the grains in a pomegranate or the seeds in a water-melon, and sometimes still more regular in arrangement. Remembering the sexual system as developed in flowering-plants requires, previous to the formation of seed, the Presence of the stamen and the pistil, respectively the male and female elements ; we look for their counterpart in these plants, and 674 Our: Fresh-Water Alge. find it in the presence respectively of antheridia and archegonia. In the violet batrachosperms of fresh water these organs are pro- duced on separate individuals. The antheridia contain small motile bodies, antherozoids, analogous to the pollen contained in the anthers of flowering-plants, and to the spermatozoids of animal life. These antherozoids find their way upon the other plant to where a long hair-like tube (the trichogyne) opens, through which their fertilizing influence reaches the protoplasm mass in the bulbous base of the tube (the archegonium or carpogonium). The proto- plasm on fertilization swells, divides, usually forms new cells around it, as if walling itself in, and then a series of new cells within, many of which become spores, the whole fruit so formed becoming as full of spores as a stramonium pod of seeds, and generally resembling the latter in their position as well. There is great variety of form among the alge of fresh water, even among the unicellular species. It might be thought that these species, where the whole plant is composed of but a single cell, would present little variety ; especially when it is considered that such simple cells commonly float loosely in the water, and in situa- tions enabling the supposed normal spheroidal cell-form to develop itself, free from the influences of crowding or lateral stimuli. But not so simple is the plan of nature, and a great range of shape exists among the single-celled algæ, from the spherical of the common protococcus of our trees and walls to the bur-like spiny Polyedrium. For instance, one Rhaphidium is crescent-shaped, another needle- shaped, another unicellular alge is shaped somewhat like the letter S, another like a J, anothera C. The Botrydium is balloon-shaped, the Chytridium often urn-shaped, others appear as little discs, others ellipses, others cubical or pentagonal. When associated in masse, pressure and the exigencies of growth change the shape of those naturally circular into irregular polygons. Some species of Ophio- cytium grow into curious coils; some Polyedriums are exact : triangles, others take the form of a Greek cross. Extend our view to the desmids and diatoms, which are also of the unicellular alge of fresh-water, and the number of cut and fantastic forms which a plant of a single cell may present, becomes indefinitely increased. The larger number of species of the fresh-water alge are, hows ever, of more than onecell. Of these multicellular alge some grow Our Fresh- Water Alga. 675 into discs, as Coleochzete, some expand into a leaf-like membrane, as Prasiola, or widen from hollow spheres and tubes into broad undulating sheets like the Tetrasporas, others grow in solid globular masses, as the Cheetophoras, one species of which occurs in the form of little green balls like peas, and hangs on dry grasses and other supports in quiet pools in spring. Others of looser texture, expand into an indefinite and irregular mass which will crumble at a touch, or form a gelatinous stratum which slips like oil through fingers that endeavor in vain to raise it from the water. Many others » become firmly adherent crests on rocks, especially under falling water. Most of the more beautiful species become filaments, usually formed of cells placed end to end, sometimes composed ot several or many such filaments bound together, either branching or not, and attaining particularly fine development in the Batracho- sperms, where the many branched and forking filaments are clad with radiating whorls of smaller branches, often in the most perfect regularity. Very commonly gelatinous in substance, many of the larger species are too frail to bear lifting out of the water, and yet endure considerable stress of their native current without harm, swaying with graceful motion as becomes beings born to the water. As there are all degrees of consistency in jellies, so there are in alge, from the tough jelly of a Prasiola, to the fluid jelly of a Tetraspora. Professor Wood named his genus Pagerogala, “ frozen milk,” from its seeming to float like white curds of clotted milk in a Pennsylva- nia spring. Some Draparnaldias may fairly be called succulent, others approach nearest of any of our alge to the wiry character ; the Lemanea issometimes almost leathery ; Spirogyras feel under the fingers like a lock of hair ; some of the largest Confervee are tough enough to support considerable weight, and have such strength of fibre that German ingenuity has tested their capability for textile use, and not only made mattress-stuffing and paper from them, but actually fabricated them into coarse trowsers, as if to show that the common phrase “clad in weeds” is not incapable of the most literal of fulfilments, Stranger still than any Confervæ, are the mailed knights among the alge, the little diatoms, absolutely unyielding and en- cased in silex, like so many little glass boxes under the microscope all curiously chased and set with flashing points and knobs. Some of 676 Our Fresh-Water Alge. the Charas secrete instead of silica, a sheath of carbonate of lime about themselves, until the whole plant seems a succession of joints of stone, or links of white lime, giving it its popular cognomen of stonewort. The colors of our fresh-water alge are varied to a degree that may surprise the student who expects only green. There is consid- erable variety even in their green, from the usual grass-green of the Spirogyras to the pea-green of some Palmellas ; the little “ water- flower,” so to render its name, Anabcena flos-aquee, is a verdigris- green ; Chlamydomonas hyalina is called by Wolle a milky-green- Many shades of red are found, vermilion in Chlamydococcus, scarlet in Thorea, blood-red in Glaocapsa sanguinea, amethystine in Lepto- thrig tinctoria; Hildenbrandtia is often purple, one of the Chantran- sias is rose-purple, a Lemanea is violet ; species of Chrodlepus range through ash, yellow and orange to golden-red ; Tuomeya is said to be olive-colored, Hydrurus ochre ; some Vaucherias are brown, one Gleocapsa is black ; a Leptothrix is straw-colored, another fawn, 4 Chantransia steel-blue, a Cylindrocapsa pearly. Many preserve their color when dried; others change, some simply by fading to 4 lighter shade of their previous color, others to a new tint; one Batrachosperm is described as at first of a mouse-gray color, then yellow, and on drying, violet ; Chantransia macrospora and Thorea are, when living, dark green, but dry a beautiful purple-violet ; the Sweet Chroolepus is tawny when fresh, changes to an ashen-gray an finally greenish ; a kindred species is reddish-orange when olive, light yellow on drying ; Zygnema purpureum changes from yellow- ish-green to dark purple; Lyngbya tinctoria, says Wolle, from purple to violet steel; Vaucheria dichotoma may stand as type of the change so frequent in the higher plants, from green to brown- Many alge unite several colors at the same time ; almost all do so when we compare the spores with the vegetative growth ; a remark- able instance of variegation in vegetable growth alone is seen 1m 3 new Lyngbya found by Wolle in the Lehigh at Bethlehem, Pennsylvania, waving in tufts six inches long, “ the one bright-blue green, lower parts changing to yellow-brown ; and @ last fading out to a colorless base.” Few of the odors possessed by the alge have received a name Out of the 1300 species recorded in this country by the Rev. Our Fresh-Water Alge. 677 Francis Wolle, there is perhaps but one which has an odor remark- ably offensive : this, the Hydrurusis, however, so unpleasant that the Dane Lyngbye remarked of it seventy years ago that “it could be endured only by an algologist.” Bory called attention early in this century to “the most peculiar odor” of Lemanea when burned. Extend the view to the Charas, and to the diatom Schizonema, and a number of species of imitating or unpleasant odors are met; but the number of algz which are in themselves possessed of much odor ofany kind is few. If any persons associate disagreeable odors with the alge, it is doubtless from confusing the odor of a place with that of an alga happening to be at the time its resident. Nor are the alge without examples of exquisite fragrance ; man might not have thought to look here for the sweetest odor, but Nature has not forgotten to add that charm to some of these, her lowly children ; one of them Chrodlepus odoratus, has been known in Denmark for over seventy years as the “sweet conferva”; it grows also on the bark of shade trees along highways in Pennsylvania. Perhaps more interesting still is the fragrance of the violet-moss, Chrodlepus iolithus, which attracted the attention of Linnzeus almost a century and a half ago; it grows asa thin glaucous, green or reddish- orange layer over stones in the Alps and in our own country in the White Mountains, causing them to “give forth a strong odor of violets.” The Swiss are said to earry these stones home and by occasional moistening, to renew the odor from time to time. These Alpine people call it “Veilchen-moos ” and the“ Veilchen-stein ” ; and this latter was adopted as its name in science by Linneus, for the specific name he gave it and which it still bears, is to be trans- lated Violet-stone. The size of our fresh-water algæ has been already referred to as commonly microscopic ; yet there are many of considerable dimen- sions. About Washington we have Tetrasporas growing a foot long, beautiful undulating sheets of translucent green floating out on flowing water; some of our Cladophoras are still longer ; and the sac-like Water-nets and the string-like Conferve equal or exceed them, Any locality may yield however, for one specimen of six Inches, a score of but one inch, and for each of the latter, an equally increased proportion on or below the border-line of vision. Many minute algæ become very conspicuous by reason of their 678 Our Fresh-Water Alge. immense numbers however ; sometimes the whole surface of a lake is covered with them. For several years a little pond near Wash- ington attracted my notice by its uniform dingy green ; examination y the microscope proved regularly that it was due to presence of myriads of a very minute alga, a Staurastrum, a pretty little desmid with six radiating points of green. The Bavarian lake, the Schlier- see, grew turbid under the ice of the winter before the present, acquiring a general green or blue, due, suggests Dr. Harz, to enormous quantities of the microscopic alga Palmella uveeformis : then the color changed under the ice to a yellow-red and at last to peach-color from the incoming of another alga, Clathrocystis roseo- persicina, which is said to have attacked and destroyed the other. This fittest survivor, conqueror in the battle of the algal hosts under the ice, was found lurking in wide expanses of beautiful peach color on the mud bottom of Babcock Lake here in Washington, recently drained to assure the safety of the Washington monument. The green surfaces of stagnant pools everywhere familiar, are also examples of minute algæ occurring in vast masses. The larger species may be mounted on cards or sheets of unglazed paper as is so common with the marine alge ; or on sheets of mica for coarser microscopic examination; or preserved for the same purpose in bottles of carbolized water. My practice is, however, to preserve specimens forthe microscope, large or small, in cement cells, using as a medium King’s fresh-water alge fluid; specimens of three or four years’ standing still remain unchanged. Some species may be collected throughout the year, even under the ice ; in the city of Washington many are constantly abundant as green coatings on trees, walls and stone steps ; others live in the drinking fountains, species, as Draparnaldia plumosa, which exist only in pure water ; others are to be sought on the damp wood work of pumps; still others in the conservatories, on damp bricks and flower-pots and m the soil. The mud of the Potomac margin contains its own species and there the Vaucheria waves in profusion ; Oscillarias, Palmellas, and other unicellular species abound; and outside of the city, springs, streams and pools are each full of their treasures, wet ban and even meadows yield their own peculiar species ; and the early spring pools filled by Potomac overflows are especially the haunt of the Algee. Review of North American Paleontology. 679 And now if interest has been awakened in these minutest of the pet nurslings of nature, the next step is to collect, examine and preserve them. Do not stop at that point let me beg of you, for it is but the threshold ; but seek to discover the entire life-history of the species around you. Uncounted problems of supremest interest await the verdict of those researches. | Only by such work can the foundation of a true and permanent classification of the alge be laid. Questions of far-reading importance follow regarding their relations to the fungi, and to animal life, and their ultimate part in the scale of nature. Uses the alge may have, many and as yet unknown ; but perhaps none more important will ever be discov- ered than their service which science already knows, that of furnishing a means by which to learn of the origin and the pro- cesses of life. The algæ as among the simplest of living things stand close to the gateway whence life first entered into the world, and invite the hope that their investigation may yield many im- portant additions to the world’s knowledge of what life is.

THE DIKES OF THE HUDSON RIVER HIGHLANDS. BY J. F. KEMP. ŢEE cuts of the West Shore Railway, on the Hudson river, above Haverstraw, and below Cornwall, have done much service to geology in bringing to light the subsurface and unaltered structure of the Archæan rocks. The Stony Point cut did more than any other exposure to convince Professor J. D. Dana of the intrusive character of the now famous Cortlandt series.! It exhibits as well one of the most interesting examples of the contortion of mica schists on the contact with intrusive rocks which any known area affords. Here also Dr. Geo. H. Williams found the types of his hornblende-peridotite? and was especially aided in his careful studies of the series. Beyond Stony Point the railway crosses the belt of blue limestome so extensively quarried at Tomkins’ Cove, and then in the foot of the Dunderberg meets the main mass of the Highland Archean. Through this it has made its way by cuts, excavations and tunneling a distance of seventeen miles to Cornwall, where it again passes off the Archean. Am. Jour. Sci., III Series, vol. xxviii., p. 384. Ibid., vol. xxxi., p. 29. 9 . . 692 Dikes of the Hudson River Highlands. The reconnaissance survey of Dr. Britton! and Mr. Merrill over this line, in connection with the New Jersey survey in 1885, brought to light some, at first sight, rather obscure dike rocks which were entrusted to the writer for determination. Their interesting char- acter, however, encouraged further investigation in the field by him the past summer, and this has led to the following results. In the October School of Mines Quarterly (Vol. IX., p. 33), Dr. Britton has outlined the results of his work. In brief he subdivides the Archean into a basal “ Massive Group,” a middle “ Iron-Bearing Group,” and an upper “Gneissic and Schistose Group.” These members, as remarked by Dr. Britton, shade more or less into one another, nor is it always easy to sharply define the individuals. In the particular section under consideration we have especially to deal with the iron-bearing and massive members as containing the dikes, for the area which is notable for their absence is regarded by Dr. Britton as belonging to the upper Gneissie and Schistose series. Of the dikes between Tomkins’ Cove and Jones’ Point the writer is prevented by the unfortunate loss of a note-book from speaking with the same accuracy of location as in regard to those remaining. There are some present, though in but few instances. One slide shows a hornblende-porphyrite very similar to one found inland and about two miles west, to be described and figured in a pape? forthcoming in the American Journal of Science for September. This is probably an outlying dike of the Cortlandt series. From Jones’ Point to Iona Island the railway skirts the Dunder- berg. The rocks are gneisses, with evident laminations that strike on the average N. 40 E. Just above Jones’ Point, and at intervals for two miles to the north, they are seamed with dikes. Eleven such masses were noted. They vary from six inches to twenty feet wide, and are in almost all instances very badly altered on the exposure. In fact they weather much worse than the enclosing walls, and frequently show a recess from which the specimen has to be fairly dugout. Under the microscope enough of the structure remains to show that they were in all cases either diorites or horn- blende-porphyrites, consisting either of a holocrystalline aggregate of hornblende, plagioclase and magnetite, or of a ground mass n° 1 See Rept. State Geol. New Jersey, 1886, p. 74. PLATE XII. 2? a ee T aR — a3 — BN Co Section of Dyke-rock from the Highiands. Dikes of the Hudson River Highlands. 693 merely a structureless alteration product with occasional er; © 's of hornblende, plagioclase and magnetite. Pyrite is sometimes seen} the same is true of biotite and small prisms of apatite. The mag- netite shows indications of titanium. The Dunderberg exposures are rather conspicuously contorted and broken. The strike of the laminations of the gneiss, while generally northeast, cannot in all cases be determined. The dikes seem sometimes parallel with them, sometimes notably run across them. They may or may not have experienced some or all of the metamorphic processes through which the wall rocks have passed (an idea to be more fully developed later), but the porphyritie structure would indicate the contrary. Much in the way of contact influences, if anything, cannot be detected. They are not far from the neighboring Cortlandt series. They may have been connected with it. This at present cannot be affirmed or denied. North of the railway station at Iona Island, a belt of horn- blendie schist, with great masses of hornblende and epidote, is encountered, This association is quite typical of certain localities in the Iron Bearing group, and strongly resembles the same associa- tion of the two minerals to be seen at the Todd! Mine in Sprout Brook Valley, northeast from Peekskill. This last is on the line of strike from Iona Island. It is not surprising, as the writer was informed by a resident, that explorations have been made in the southwest, finding, however, nothing but lean ore, too poor to work. These outcrops possibly form a “range” similar to the well-known ranges of New Jersey, with the Croft and Stuart or Sunk mines at the extreme northeast. ‘Between the Poplopen creek drawbridge and Fort Montgomery, 18 to be seen a bed of crystalline limestone or calcite, filled with rough crystalline inclusions of an undetermined mineral, probably pyroxene, and much graphite. This is in all respects similar to those noted by Dr. Horton further to the northwest,” although this Particular outcrop seems not to have been observed by him. At the north end of the first cut above Fort Montgomery is a very curious narrow dike of dense black rock, four inches wide, traceable twenty feet or more vertically. It runs diagonally across the laminations of the gneiss, and seems to fill a well-defined crack. ! Cf. Tenth Cen 2 Geol. of N. apk ah a . 694 Dikes of the Hudson River Highlands. Under the microscope it is seen to consist chiefly of innumerable small but well-developed hornblende crystals, having sharply de- fined prismatic and pinacoidal faces. They vary from 0.02 mm. to 0.05 mm. in width, and are about five times as long. The accompanying drawing (Fig. 1), from a micro-photograph, illus- trates the structure. The actual field is one millimetre in diameter. With the hornblende is some plagioclase not very well developed, as the rock has more or less of a porphyritic facies. Magnetite is sparsely scattered throngh it in very small grains. Slides of this rock are well nigh indistiaguishable from those of the diorite described by Hawes from Campton,! N. H., and later by Professor Harrington from Montreal, resembling? less closely the similar diorite described by the writer from the Forest of Dean mine? Mr. L. M. Dennis, Instructor in Chemistry in Cornell University, has made the following analysis, No. 1 in duplicate. No. 2 is of the Campton dike by Hawes, No. 3 of the Montreal dike by Professor Harrington, No. 4 of the Forest of Dean by the writer. I II.

Beyond Fort Montgomery, except in the case just cited, no dike rocks are to be seen until Cro’ Nest Mountain is reached, north of West Point. The interval is made up of gneisses, very feldspathic, and considered by Dr. Britton to belong to the Upper Schistose Series. They have peculiar feldspathic masses in them which must be considered in any question of origin or metamorphic action. Great cleavage faces of feldspar as large as the hand reflect the sunlight from the sides of the cuts. Cro’ Nest and Storm King form the northern boundary of the Highlands west of the Hudson. They consist of rocks which are described by Dr. Britton! as quartz-syenite,and are considered as typical of the massive group. The laminations are generally apparent, but in many instances the rocks present a well-nigh massive appearance. Running like broad black ribbons in directions generally vertical, across the exposed faces are numerous dikes varying in width from a few inches to forty feet. Fifteen were noted in Storm King, six in Cro’ Nest. These dikes are very uniformly holocrystalline aggregates of hornblende, augite and plagioclose as principal minerals, with subordinate magnetite and apatite, and occasionally a little biotite, orthoclase and quartz. The hornblende and augite are gener- ally associated, but there are instances in which each appears alone with the other minerals mentioned. The augite appears alone especially in those dikes whose wall rock is most broken and contorted. The hornblende is of the common brown variety strongly pleochroic. It is never in well-bounded crystals, but always in irregular masses, whose external shapes are conditioned by their neighbors. It frequently contains included the apatite and magnetite, and the masses vary from 0.5 mm. to 1.0 mm. in width, but are relatively somewhat longer. In the more altered specimens the hornblende tends to bleach out to a green variety. The augite is in the same irregular masses of light green color, and contains the same inclusions, but on the whole is less prone to do so. The biotite is far less abundant than the two just men- * The School of Mines Quarterly, vol. ix., p. 34. 696 Dikes of the Hudson River Highlands. tioned, contains, however, magnetite inclusions, but in other respects shows no peculiarities worthy of note. The feldspar is in irregular masses, well twined, and contains not unfrequently as inclusions the hornblende and augite, as well as magnetite and apatite. By powdering the rock and carefully separating the feldspar by means of the Thoulet’s heavy solution the specific gravity was found to lie between 2.67 and 2.70, bringing it near Labradorite." The magnetite is in coarse, irregular masses, showing no indications of titanium. ‘The apatite prisms are also quite coarse. It follows, therefore, from the relations above set forth, that, according to the well-known general law, the magnetite and apatite have been first to form, and have then been taken up in the mass of the horn- blende, augite and biotite in their subsequent crystallization, while the feldspar has been last of all to form, as it includes all the others. In the accompanying figure (Fig. 2), taken froma micro- photograph, the structure of a typical specimen is shown. he actual field is 4.0 mm. in diameter. The different minerals, horn- blende, augite and plagioclase are well indicated by their characteristic cleavages. In the matter of classification these rocks are perhaps most nearly allied to those called by Rosenbusch Camptonites,” but 1 the matter of structure it should be stated they differ widely from the typical Camptonites in the writer’s possession, for anything like a porphyritic structure is entirely lacking. Although differing from the typical and widely-known kersantites in the small ` amount of biotite contained, they yet, with some described varieties,“ seem structurally related. A normal kersantite has been described from this region by Dr. Newberry," which seems to form a boss in the enclosing gneiss at Croton Point. 1 Rosenbusch.

Dikes of the Hudson River Highlands. 697 In some cases these dikes are parallel to the laminations of the enclosing gneiss or syenite, in other cases cut across them. Many would seem at first sight to be interbedded masses, and the writer would confess himself inclined at first to take the view that if these mountains are to be considered metamorphosed sediments, then these dikes represent strata of composition different from the remainder, There are, however, illustrations, as stated above, of unconformability, and not only that, but of two separated and unconformable branches joining above while separated below. (Spec. 82 and 33, two dikes each twelve feet wide just south of Cro’ Nest flag station.) They are, therefore, esteemed of undoubted intrusive origin. he dikes are not infrequently faulted by feldspathic segrega- tions. In Storm King, above the paving stone quarry, six, from four inches to eighteen inches wide, are exposed, four of which are faulted by such a segregation. The inference from this is that the dikes are of great geological antiquity. These feldspathic masses consist chiefly of very coarsely crystalline orthoclase. Such a mass we know would form only under high pressure and great heat,’ and indicates the changes through which these rocks have passed since the dikes were intruded. The geological date of the metamorphism, if such it were, which gave these syenites or gneisses their present form, it is not easy to state, but from the comparatively unchanged condition of the strata lying against them to the north at Cornwall, it must have been before the Hudson River Period of the Lower Silurian. In the writer’s opinion the dikes were intruded in Archæan time, and have experienced the same influences which have given the gneisses their bedded character. It cannot be affirmed that the dikes themselves are metamorphosed from their original structure, but it is interesting to note that they exhibit even in their narrowest examples a perfect holoerystalline structure, nor is any amorphous or porphyritic matter to be detected. e infer from this either that they were intruded between highly heated walls, and that they cooled slowly and under pressure like a plutonic rock (Tiefengestein); or else that subsequent metamor- * Hautefeuille, Comptes Rendus, 1877, t.

The metamorphism of igneous or intrusive rocks is a subject now attract- ing much attention, and has important bearing on the origin of the Archean.' As for explaining the slight bedding or laminations of the wall rocks by previous sedimentary stratification, while it is not easy to adduce any positive facts against it, the writer does not believe in it. It seems most reasonable to regard the laminations as due to pressure exerted normally to them, and that the pressure was in almost all cases normal to the dikes as well. The origin of these well-nigh massive basal rocks of the Archean is certainly at present a most uncertain theme. Yet, although it is readily to be seen from much that has been written how easy it is to indulge in laboratory speculations which afford little else than contro- versial material, the writer would nevertheless advance the conclu- sions drawn from the structure and composition of these dikes as legitimate if not incontrovertible inferences. SCIENCE IN UTOPIA. BY ©. L. HERRICK. I has doubtless been a matter of regret to many of my r readers that since the publication of the valuable memoirs of Sir Thomas Moore upon Utopia no one has succeeded in penetrating the veil of mystery hanging over those happy islands. For my own part I have often amused myself by wondering whether egress is as difficult as access and in imagining a sort of espionage of modern institutions by that conservative and self- satisfied community. Very unexpectedly my vagaries were suddenly proven realities and I am permitted to record the results of an extended conversation with a representative and very intelligent member of the scientific congress of Utopia. 1 This has been strongly advocated by Lehmann. Entstehung E Altkrystallinen Schiefergesteine. Reviewed by D. Geo. . Wile in Am. Jour. Sci. III., vol. xxviii., p. 392. Science in Utopia. 699 My present purpose is simply to repeat a few facts communicated by this gentleman which seemed to me well worthy of examination if not imitation by the learned bodies of our own land. For further details the reader is modestly referred to the illustrated memoir now in preparation under the joint superintendance of my Utopian friend and the author. These remarks must, therefore, be simply regarded in the light of a preliminary notice (Vorläufige Mittheilung) for which, by the way, 4 am assured there is no synonym in Utopian language or praxis. Mr. Non! Nemo himself is well worthy a passing glance. Though below the medium stature of Americans he possesses a perfection of physical development not seen in the intellectual classes of our own people. Upon my remarking upon this pecu- liarity so disassociated in our minds with a studious habit, Mr. Non Nemo explained that in Utopia a high degree of physical per- fection is demanded of public servants and candidates for admission into the ranks of the “ Geleherte,” and that such progress has been made in mastering the laws of heredity that it is rare indeed to find a case of reversion to inferior types among the children of the upper classes. Of course I eagerly inquired whether the attempt consciously to comply with the laws of heredity did not seriously impair the spontaneity of domestic and social relations. But though he admitted that there was some temporary disturbance, Mr. Non Nemo stated that the principles had become so indelibly stamped upon society and embalmed in social precedents that the compliance with the necessary regulations had become instinctive and no con- scious limitation of social liberty was experienced. The genial foreigner expressed great surprise at the general neglect of these laws in this country and went into an uncontrollable fit of laughter when he heard of the system of vicarious physical training now in vogue in American colleges. Gladly as we might linger upon these and similar topics the present occasion Suggests that we must pass to the more directly scientific aspects of Utopian life, Some incidental reference to international congresses brought out ! Non in Utopian nearly corresponds to Von in German or De in French. 700 Science in Utopia. many inquiries on both sides in the course of which the following facts were elicited. In Utopia during recent years the prosecution of science has enormously increased and, as usual, this increase has mirrored itself in the literature. Under the old system, which closely resembled our own, there was neither official supervision nor ~ recognized limitation upon publication. The great mass of literature soon made specialism necessary with constantly narrowing limits, until the broader purposes of scientific study were rapidly being lost sight of in the attempt to meet the bibliographic obligations thus imposed. Just at this juncture it happened that the continent of South America was opened to the Utopian explorers (whether this occurred before or subsequent to 1492, I was unable to ascertain, by reason of my unfamiliarity with the standards of Utopian chronology). The result was an alarming increase in purely faunal and systematic publications. The case soon became so desperate that a congress 0 the sciences was called to meet in the capital city which, after mature deliberation, proposed a permanent organization with the following functions and powers. j The organization was called the parliament of philosophy and is a strictly representative body, so guarded that personal jealousy among competitors can not easily exclude worthy applicants, while the financial burdens are nominal. : A council elected at the biennial session of this parliament 18 charged with the duties of a bibliographic bureau. In this work they receive aid from the department of state corresponding to our patent office and congressional library, here united under onè management. At each session committees, appointed by the various sections, report for adoption a scheme of working classification the department presided over by the section both as relating to the distribution of subordinate topics and the systematic arrangement of the categories of natural species. While conformity to the scheme adopted is not binding upon authors, it forms a more or less perfect approximation to current views and is the official standard for reference during the ensuing term. This being settled, writers cannot secure recognition for publications until they have been entered in the proper departmen of the bureau of bibliography, which is also charged with the duty Science in Utopia. 701 of distributing a monthly official statement of all titles registered under the proper rubric. The expense of such a record is jointly provided for by the parliament and the general government. In case a publication contains proposals of new species or new modifications of classification the rules further require that a separate slip bearing the name and a diagnosis in the scientific language of Utopia of each such species or modification proposed accompany the paper. These are entered under the proper head if, after examina- tion by a special committee they are found to conform to the rules of nomenclature adopted by the parliament. If the name be im- perfectly formed or duplicated the committee is directed to return to the author for correction. The name and systematic position of each species is published in the monthly bulletin. At the next biennial session the proper sections of the parliament or committees appointed by them examine the diagnoses of species proposed during the previous term with a view to eliminate any possible synonyms. It is always understood that uncertainty stands to the credit of the proposed species. The work of this committee, my informant said, was found very delicate and there was difficulty in inducing those best qualified to serve. However, its reports are subject to revision in open section meeting and, on the whole, are most useful. The result, continued my informant, has been to place wholesome restraint upon the professional species-maker as well as to make it possible for all conscientious students to avoid infringement on the rights of others. The fear of the scrutiny of the committee- room acts as a check on careless description, while the biennial reports periodically clears up any ambiguity. Of course there were many who felt themselves aggrieved by arbitrary decisions, but not so many as those who under the old lack of system justly complained of the freaks of fortune and the injustice of powerful rivals. The general opinion seemed to be that, in the long run, “very one received a fair measure of justice from this novel parlia- ment, ; It also appears that this central organization has depositaries in all the larger cities of Utopia and in the libraries of the various learned societies and that it is becoming quite the thing for every author to send a copy of systematic papers to each of these 702 New Species of Field Mouse. depositaries for convenience of examination. Some return is made by the government but just what my informant neglected to state. I was much interested in Mr. Non Nemo’s account of the ad- justment of a conflict between local bureaus of research (somewhat like our state geological surveys but with a wider scope), and the official scientific commission of Utopia. This subject, however, we hope to fully elucidate in our contemplated memoir and will simply remark that the adjustment charged the local bureaus with the detailed examinations and collection of material, and imposed the duty of turning over a certain part of the facts and material to the central organization, which reduced the whole to systematic form, and ineluded in its report an epitome of the more detailed publications of the local bureaus. Several of the provisions described above seem to the writer adapted to the work of the Association for Advancement of Science and later to the International Congress of Sciences and, I trust, we may arrive at a satisfactory system without the long period of experiment and bitterness passed through by science in Utopia. DESCRIPTION OF A NEW SPECIES OF FIELD-MOUSE (ARVICOLA PALLIDUS) FROM DAKOTA. BY DR. C. HART MERRIAM. I G some small mammals collected during the past season at Fort Buford, in Northwestern Dakota, by Mr. vo Bailey, are four well-prepared skins with skulls of a very light- colored Arvicola, a careful study of which has led to some pute! tant and unexpected results. Concerning their habits, Mr. Bailey contributes the following: “ The pallid Arvicolas seem to be ges mon at Fort Buford. They show a decided preference for a north side of steep hills. I have not found them on the p i southeast, or southwest sides. The only reason I can suggest p this distribution is that the twilight (their favorite hour) is longe New Species of Field Mouse. 703 on the north side. The hills where I have found them are all steepest on the north side, which may have some effect, though there seems to be no difference in the vegetation on different sides. Like other Arvicole, they have many holes, and prob- ably live in families or colonies, although I have not caught more than one at a group of holes; but from the difficulty in catehing them this does not signify anything (have caught only four). “Where there is grass or weeds, their holes are connected by beaten paths in the same manner as those of Arvicola austerus, but in many places they are in bare clay. Their food seems to consist largely of the flowers of certain plants, judging from the remains of flowers scattered around the holes, and from the contents of their stomachs and excrement. When these plants grow near, there are usually pieces of stems and blossoms of Liatris graminifolia adn Artemisia frigida lying about, but many other plants and grasses seem to be eaten. They feed largely on the seeds of Eurotia lanata. I found a place near their holes where something had dug down to a partly-eaten bulb of Liatris graminifolia. Probably these bulbs form a part of their diet, as is the case with Arvicola austerus. I placed corn, oats, cactus seeds, and seeds of weeds around their holes, but they remained untouched. The same was true of bread and cheese, and fried cake was seldom eaten. They seem suspicious of traps, and evidently leave their holes when traps are set near them. I have caught several grasshopper mice (Onychomys leuco- gaster) and Western white-footed mice (Hesperomys leucopus sonori- ensis) at their holes, and think these species either drive out the Arvicolw or else inhabit the old holes.” The exact locality where these specimens were obtained, writes. Mr. Bailey, “is not actually in the extreme ‘ bad lands,’ but near the edge, where the land is about ‘half bad.’ From the fact that they live entirely in the hills and usually near the tops, where it is very dry, it might be inferred that their true home is in the ‘bad lands?” In comparing these mice with the other known North Ameri- “an species of Arvicola, two. striking external differences are observed, namely, (1) extreme paleness in coloration ; (2) extreme shortness of tail. The color is paler even than that of the Muskee- get d mouse (Arvicola breweri), and the tail is shorter than that of any other species, not excepting A. pinetorum, in this respect agreeing closely with Synaptomys cooperi. The ears are unusually 704 New Species of Field Mouse. prominent, but this peculiarity probably is subgeneric. An exami- nation of the skulls and teeth at once shows the animal to belong to tke subgenus Chilotus of Baird, to which but one species (Arvicola oregonus, from the Pacific coast region) has been hereto- fore definitely assigned. The range of the subgenus is thus ex- tended more than a thousand miles to the eastward. The present species is nearly as large as Arvicola riparius, and consequently considerable larger than A. oregonus. Of the four specimens at hand, two are males and two females, all fully adult. The females bear evidence of recent nursing. The species may be easily dis- tinquished by the following diagnosis : ARVICOLA (CHILOTUS) PALLIDUS sp. nov. Type no. 3852, ọ adult, Merriam Collection.

The latter esi is all mountains. Large flat lands are nowhere to be seen, mountains rising at once to a great altitude.! As a rule one hi E.

As a consequence of this topographic peculiarity the soils are here very different from those in Sweden, and particularly noticeable is the exceedingly thin layer that covers the mopentains. This is true in the same degree as the surface is more or less broken, and it is only in the narrow mountain passes that soil exists to any considerable depth. This is worth noticing in comparison with the well-known fact in Sweden that the outcrops of rock are most abundant where the land is high and broken, the explanation of which seems to be that, in a much-broken tract of ice-covered land, the lower parts of the ice must have but a slight motion, whilst its upper parts meet with but few points for their attacks. As for the moraines of Greenland, they are essentially only ground-moraines, and inner-moraines, and, as a special form of those, one will also find border-moraines and terminal-moraines. Where the ice runs out to form ice streams, can be observed lateral moraines and, in exceptional cases, middle-moraines ; these last two kinds are of minor importance. ` ‘ The unmixed ground-moraine rarely comes to view, owing to its position beneath the inland-ice and under the other forms of mo- raines, It may, however, be observed at the side of a jokel-gate (ice-arch) or other cut in the edge of the inland ice, its character- istic features being rounded and scratched boulders imbedded m 4 clayey mass of bluish color due to the presence of iron salts of lower oxidation.

Such occurrences become gradually more rare as one proceeds further up on the inland-ice and away from land. How the ground-moraine may occasionally form ridges on the top of the ice will be mentioned further on under the heading of border- moraines. The most important moraine is the inner-moraine. From its location in the very mass of the ice it will gradually appear on the top as the ice melts away from its surface. It is thus generally found wherever the inland-ice borders upon land, whether this be the nunataks or the coast-lying land. Sometimes it consists of scat- tered stones and patches of gravel not forming a continuous cover- ing, and then there are generally no considerable moraine deposits on the land adjacent to the ice. At other places it occurs in such abundance as completely to hide the underlying ice, giving the impression of deposits from a departed glacier rather than of a moraine still resting on the top of a glacier. The greatest inner moraine observed by Dr. Holst was one along the southern edge of Fredrikshaab’s ice-blink. It had its eastern limit close to the lake Tasek Atdlek and extended along the south- ern side of the ice-blink for a distance of nearly twelve miles. Its width, not far from the eastern end, was about half a mile, but the western half of it was more than a mile wide (in one place 8,300 feet), until near the western end it again became narrower. Its ickness is always greatest near land, but here it is often quite difficult to estimate its actual thickness, as it sometimes forms a compact covering, only in some fissures showing the underlying ice. This uneven thickness of the moraine-cover offers to the ice a pro- portionally varying protection against the sun, It thus happens that the unequal thawing moulds the underlying surface of the ice into valleys and hills, the latter sometimes rising to a height of fifty feet above the adjacent valley, and being so densely covered with moraine material that this completely hides the ice core, which, however, often forms the main part of the hill. Farther in on the ice, the moraine gradually thins out. At the locality just referred to, the moraine-cover, 3,000 feet from land, measured several inches in depth; still the ice .was seen in some bare spots, Beyond 4,000 feet from land, the moraine formed no continuous cover, and at 8,300 feet it ceased entirely, with a per- 708 Holsts Studies in Glacial Geology. ceptible limit against the clear ice. Only some scattered spots of sand and gravel were met with even a few hundred feet farther in on the ice. Dr. Holst estimated the average thickness of the mo- raine taken across its entire width near its eastern end at one to two feet. The limit between the moraine-cover and the pure ice is always located at a considerable though varying elevation above the edge of the inland-ice. In the instance of the above-mentioned moraine it varied between 200 feet and 500 feet. The inner-moraine consists of stones, gravel and sand, mixed together. The largest blocks rarely exceed six feet in diameter, whilst by far the greatest number of them are much smaller and of a nearly uniform size. Rounded and scratched stones, derived from a ground-moraine may, in exceptional cases, be found among them, otherwise the material of the inner-moraine is characterized by its angular form, it is equivalent to the s. c. “ surface-grav a “upper boulder-gravel.” There can be but one opinion with regard to the origin of the inner-moraine. When pushing forward over higher ledges the inland-ice disintegrates the rock and carries the débris along. In its further course the ice will for some time retain nearly the same level, and the rock fragments will thus be located in the ice, not under it. As the ice melts away above on approaching to land this inner moraine will gradually come to the surface. t seems proper to apply a special term for those ridge-like mo- raines which occur on the top of the ice, near land and parallel to it, and are met with especially in places where the land has pro- iecting points which indent the ice; the moraines around the nunataks seem to be partially of the same character. These mo- raines surround the said points or the nunataks more or less m curves. Being thus confined to the borders of the inland ice they may appropriately be called border-moraines. a e border moraines north of the Arsuk fjord ice-river are visible far out on the sea off Ivigtut. Dr. Holst examined one that sur- rounds the southernmost strip of land at a distance from land i about 2,000 feet. Itis not one continuous ridge but consists of several disconnected portions arranged in a semi-circle. One i these portions was about 200 feet wide and thirty-five feet pe j This moraine was mainly a ground-moraine, probably forced up y some elevation of the ledge under the ice. Holsts Studies in Glacial Geology. 709 Another border moraine to the north of Kornok’s northern ice- river, was of a different character. The stones, at least at the surface, were greatly in preponderance over the gravel. They were angular and of varying size. The moraine showed some arcua- tions, but taken as a whole it was parallel to the land. In some exceptional instances it approached closely to the land, even so as to touch one of the projecting points, but generally it was located some distance away from land. Its width was estimated at 100 feet, and its height at more than fifty feet; it should be remem- bered, however, that it might have had a core of ice. Its length was about one and a half mile. South of this moraine, and farther in on the ice, were seen three more moraines, the greatest one extend- ing about 1,000 feet in length. Two of them were parallel, one inside the other. Every moraine will finally be deposited in front of the glacier, and may then be called terminal. This term thus applied would however, be of no value. It is therefore desirable to restrict the sense of the term to such walls or osar as accumulate in front of the ice-rivers proper and generally extend across the valleys in which these rivers find their outlet. Here the moraine material gathers in such quantity and manner as to assume a character different from all other moraines. The great accumulation of material in these places does not depend on the presence of any greater quantity of such material in the ice-river than there is in the balance of the inland ice but rather on the more rapid trans- position of material in these rivers. Terminal moraines are found in front of every ice-river that — does not directly run into the sea, e.g., in front of Fredrikshaab’s ice-blink and of the ice-rivers at Arsuk fjord and Kipissako, and of the southern ice-river at Kornok. At the last-mentioned place the terminal moraine reached a height of nearly thirty feet and Surrounded the edge of the ice like the wall of a fort. At Sarkar- igsok, in front of Fredrikshaab’s ice-blink, were several walls, one mside the other, each about twenty feet high. The width of the total space covered by these walls aggregated about 450 feet. They extended along the front of the ice-blink, both north and South, as far as the observer could see. The terminal moraines are a mixture of material derived from ground moraines and inner 710 Holsts Studies in Glacial Geology. moraines, sometimes mainly from the former, at other places mainly from the latter, with the addition of material from lateral moraines where such exist. Furthermore, the terminal moraines are often traversed by jékel-rivers and numerous springs which agitate and grind down the contents of the moraine. The merely local occur- rence of terminal moraines and the mixed character of its contents, give to it a subordinate importance compared with the ground- moraine and the inner-moraine. Of still less importance are the lateral moraines and the middle-moraines. Of the latter kind none were observed by Dr. Holst. Lateral moraines are met with along the sides of the ice-rivers and at the foot of the nunataks. In the moraines are found some rocks not derived from the neighboring mountains. For this and other reasons, it seems evident that the lateral moraines are not altogether made up of débris from the adjacent sides of the mountains, but have received contributions from inner-moraines, and, in some instances, also from the ground moraine. Dr. Holst calls particular attention to the fact that in Greenland the blue and the yellow clays are formed simultaneously by the action of the same inland-ice, the former near its bottom where 1t is protected from the oxidizing influence of the air, the latter nearer its surface; and he regards the bearing of this observation as an argument against the theory, according to which the lower blue clay and the upper yellow clay in Sweden, Denmark, and Germany, are supposed to owe their formation to two different glacial periods. E. The upper-drift deposits are invariably found in process of formation in the larger valleys in front of the ice-rivers, Or, 10 ‘other words, along the greater jékel-rivers. Here they form more or less level plains, through which the river cuts its channel. Equal deposits are also met with in tracts from which the ice has departed, and here too their occurrence is confined mainly to the larger valleys in which once terminated greater or smaller 1ce rivers with jékel rivers issuing from them. The moraines from which the upper drift derives its material are partially the inner, partially the ground moraine, which first combine to form ‘An abundance of Diatoms flourishes in the waters between pang minal moraine and the inland-ice. In one place, at Sarkarigso®, vegetation displayed a brilliant yellow color. e Hols? s Studies in Glacial Geology. 711 terminal moraine in front of the ice-rivers, and the material is gradually worked over by the jékel-rivers. The force of the jékel-rivers is greatest nearest the inland-ice and diminishes as they approach the sea. In consequence, the greatest stones are found near the terminal moraine, whilst further on their size is reduced more and more until all is sand, spreading out to wide sand-plains, as is the case, for instance, off Fredrikshaab’s ice- blink. The finest impalpable material is carried out into the fjords and open sea, where it forms deposits of clay. The upper drift of Greenland shows a considerable resemblance to that of Sweden. Both are free from boulders. The gravel is assorted and stratified. The stones are well ground, although more rounded in Sweden than in Greenland. These deposits in the latter country are not unfrequently of a considerable thickness. In the bottom of the Tasiussak tjord and in a few other places they measured about 100 feet. There are, however, no typical osar in the part of Greenland visited by Dr. Holst, who found only some smaller hills to a faint degree resembling those formations. There can be no doubt that the osar are formed near and in close relation to an inland-ice. Nothing but such ice could have transported these masses to their present locations, and nothing but the enormous force of the torrents rushing from the ice could have wrought the material so thoroughly. Still it may be less certain that the ose form has been caused in Greenland by the same agencies as those that produced glacial osar in Sweden. It may be a mere accidental resemblance and the form may depend on later excavations. Such osar were formed within the time of the melting of the inland-ice. The coast-land of Greenland presents the same character as Sweden so far that it has formerly been covered with inland-ice which has long ago melted away. Why then is it that typical osar do not exist in the said district of Greenland ? Dr. Holst finds the answer to this qnestion in the topographical differences of the two countries. He refers to his earlier discussion of the formation of the glacial osar in Sweden, 4 summary of which discussion was given at the beginning of this article. As stated there, such osar are formed as sediment in the beds of rivers, having cut their channels into the surface of an inland-ice. The requisite conditions for the formation of large osar 712 Holsť’s Studies in Glacial Geology. are, among others, first, that the water-divides on the inland-ice shall be sufficiently far apart so that the water supply may be sufficiently great to form larger rivers, and, secondly, that the ice shall be sufficiently free from crevasses, which would otherwise drain off the water beneath the ice instead of on its surface. It is then evident that, in Sweden, the broad valleys and low- lands with gently rising sides must have offered particularly favor- able conditions for the formation of vast gravel-osar, whilst such osar can occur only as local formations of smaller dimensions in the mountain regions of the country. It has long been supposed that gravel-osar were entirely absent from Norway. This is, how- ever, not altogether true, but they are of rare occurrence, which fact fully agrees with the above theory. On the plains of the extreme south of Sweden, as also of Denmark and Germany, the absence of large drainage basins has hindered the formation of greater osar, although they are not altogether absent from Skane, and equivalent formations have been observed by Dr. Holst at Neustadt-Eberswalde. It is equally evident, that the topograph- ical conditions in those parts of southern Greenland above described (page 705) do not admit of any formation of larger osar. In a country so broken and mountainous, the inland ice must be full of cracks, preventing the water from gathering to any great extent over its surface. Such cracks do not necessarily exist in a moving inland ice, and Dr. Holst mentions a smaller tract of ice between Tasek Atdlek and Kangarassuk, which was entirely free from cracks, and, as a consequence, was covered with water, which gath- ered into a channel five feet wide and five feet deep, in one place separating into two branches, enclosing an island of ice, before it finally rushed into a jékel-well. Also Nordenskiöld and the Dan- ish explorers of the inland-ice met with water flooding its surface. If the above-given reasons for the absence of gravel-osar from the mountainous part of Greenland are correct, there could have been nothing to prevent such osar from forming in the less broken tracts, f. i. the district of Holsteinborg. Dr. Holst found no oppo tunity of visiting that district, but after returning home he learnt from A. Kornerup’s report of his travels in 1879 (published ™ 1881) that he had found in the Arsalik valley, N. E. of Holstein- borg, a typical gravel-ose about four miles long, parallel to the Editors’ Table. 713 present direction of the motion of the inland-ice, and having a roof- shaped top, and even sides, inclined 20° to 25° to the plane of the valley over which it extended in a meandering course. Mr. Kor- nerup also states, that the said valley is “an unusually large plain, bounded by even, gently-sloping foothills.” This observation thus fully corroborates Dr. Holst’s theory, EDITORS’ TABLE. EDITORS: E. D. COPE AND J. S. KINGSLEY. For several years past the Peabody Museum of Archeology and Ethnology, at Cambridge, Mass., has been engaged in the explora- tion of the remains of the mound builders. More lately, under the direction of the Curator Professor, F. W. Putnam, it has con- fined its labors to the mounds of Ohio, and especially to those of the Little Miami Valley. A most careful and thorough method of work has been adopted, which has resulted in each mound investi- gated telling all that it could tell. Some time ago Professor Putnam informed the Bureau of Ethnology of the nature of his work, and requested that they leave him his chosen field, the Little Miami Valley, for his own exploration. This was, of course, an eminently reasonable request. He was first in that field, and had devised his methods of research, while there were thousands of other mounds which were open to other investigators. Besides, in order that the mounds may reveal as much as possible, it is neces- sary that all in a certain region be investigated by the same hand. With a striking disregard of scientific courtesy the Bureau of Ethnology has this year sent a party into the Little Miami Valley, thus encroaching upon the very territory which was already being explored, and explored—if the testimony of unprejudiced witnesses can be relied upon—in a more thorough manner than is the case with the rapid work of the party under the charge of Professor Cyrus Thomas. Government money should be put to a better use than this, 714 Recent Literature. RECENT LITERATURE. THE SEVENTH VOLUME OF THE PAL#ONTOLOGY OF NEW especially the colossal Mesothyra oceani.

S. Fish Commission, and as especially devoted to ichthyo- logical science, he has been for years familiar with its work. Many of the important results of this work are set forth in the book mage consideration. These embrace the determination of the nature 0 the migration, and time and place of breeding of many of the marne species. This subject is in the nature of the case difficult of explo- ration and elucidation, but a great deal has been accomplished by the Fish Commission in that direction, although much remains to be done. Among the discoveries brought to light by them may et: cited the habits of that most valuable fish, the Spanish mackere protection which can be extended to it on its breeding grounds. The relative importance of the various food fishes is determin 9 not only by their quality and abundance, but by their relation ‘American Fishes.

Recent Literature. 715 other fishes, both as food and as enemies. In the former case we find the menhaden (Brevurtia menhaden), which, says Mr. Goode, is “ by far the most abundant species of fish on the eastern coast o the United States.” Millions are captured every year, without any apparent diminution of their numbers resulting. As a raptorial fish, the blue-fish may be cited. The destruction it deals in every direction is thus described by Prof. Baird: “ There is no parallel in point of destructiveness to the blue-fish among the marine spe- cies of our coast. The blue-fish has been well likened to an ani- mated chopping-machine, the business of which is to cut to pieces and otherwise destroy as many fish as possible in a given length of time. . . . As already referred to, it must be borne in mind that it is not merely the small fry that are thus devoured, and which it is expected will fall a prey to other animals, but that the food of the blue-fish consists very largely of individuals which have already passed a large percentage of the chances against their attaining maturity, many of them, indeed, having arrived at the period of spawning. . . . An allowance of ten fish per day to each blue-fish is not excessive, according to the testimony elicited from the fish- ermen and substantiated by the stomachs of those examined ; this gives ten thousand millions of fish destroyed per day. And as the ah gy of the stay of the blue-fish on the New England coast is at east one hundred and twenty days, we have in round numbers twelve hundred million millions of fish devoured in the course of a season, Again, if each blue-fish, averaging five pounds, devours or destroys even half its own weight of other fish per day (and I am not sure that the estimate of some witnesses of twice this weight 1s hot more nearly correct), we will have during the same period a daily loss of twenty-five hundred million pounds, equal to three hundred thousand millions for the season.” This book gives some means of judging of the utility of the U. S. Fish Commission. As a manual for fishermen it is the best yet published, and with the “Synopsis of Fishes of North Amer- lea,” by Jordan and Gilbert, furnishes an introduction to ichthy- ology such as few countries possess. We notice some omissions from the accounts of fresh-water fishes, ew, and refer to but one, on p. 15. Dr. Estes writes of the pike- perch (Stizostedium vitreum Raf.): “In these waters (Lake Pepin) the wall-eye is seldom found associated with any other fish than the sand-pike. It is true, however, that in swift-rolling waters, especial] under falls, we find him in company with the black bass, but believe th = 716 Recent Books and Pamphlets. the wall-eye to remain in his company. In other locations the bass easily drives the wall-eye from his feeding grounds.” This hardly does justice to the wall-eye. In the Tennessee river and its tribu- taries the wall-eye is facile princeps of the waters, not only from his size and speed, but from his courage. He holds his resting places clear of other fishes, and feeds on the black bass when he approaches too near. I have taken two black bass from the stomach of one wall-eye, of a pound and a half and a pound weight each. The wall-eye is the best food-fish of the Tennessee and its tributaries. is work is illustrated throughout by excellent Par of which we present three on the accompanying plate.— C.

Consul at Old Calabar, has in the early part of this year made a voyage up Cross River for the purpose of making treaties with the various kings and chiefs along its banks, as well as to settle various quarrels that had arisen among the natives themselves, and exercised a prejudicial effect upon the trade of the river, Mr. Johnstone was successful in concluding treaties with Umon (the first country above the Efik or Old Calabar country), Akukuna, and Iko-Morut, and also in inducing the people of those countries to resume friendly relations with each other and with Arun. Above Iko-Morut, and near Atam, the people are inveterate cannibals, and some of them treated their visitors to some startling, though happily bloodless experi- ences. Ata place called Ededema, Mr. Johnstone was dragged out of the canoe by a score of cannibals, mounted on the shoulders of the biggest, and carried off at a run to the town, where he was put in a hut with the door open, and had to bear for an hour the gaze of hundreds of savages. A smoked human ham, hanging from the smoke-blackened rafters of the house, and about a hundred skulls forming a ghastly frieze around the upper part of the clay walls of the hut, served to still further heighten the interest of the situation. Yet as soon as his interpreters rejoined him a friendly conversation was commenced, and the palaver was concluded by the return of the consul to his canoe in the same manner that he had been taken from it. Incidents similar to the above occurred several times as the voyagers proceeded, and since, though all ended in friendship, it was found that at the commencement the savages were undecided whether to look upon their visitor as a supply of food or not, Mr. Johnstone deemed it advisable to return. lateau, to the south by a high range dividing the Kaap from the foodie goldfields, and to the north by the Crocodile River. Queen’s combined stream joins the Crocodile in long. 31° 25’ E., and lat. 32’ S. The terminus of the Lourenço Marques railway will be established upon Transvaal territory at the junction of the Ko- mati and the Crocodile, on the west side of the Lebombo range. The southern mountain range isa huge branch of the Drakensberg, peaks which rise to 7,600 feet, and forms the water-shed between 720 General Notes. the basins of the Komati and Lomati rivers and that of the Kaa and Crocodile. The Lebombo range, which forms the boundary between the Portuguese possessions and the Transvaal, is but a series of low ranges not rising above 900 to 1,000 feet. From the terminus of the Portuguese railway an east and west line is projected across the Transvaal, ascending the Drakensberg, and rising at one point to 5,884 feet. There is abundant evidence that the Kaap valley was extensively worked, centuries ago, by a white race. Quarries, shafts, tunnels, adits, the remains of well-made roads, and pits of ore lying beside them for shipment, are to be found, and it would seem that the works were abandoned precipitately. Mr. Stuart attributes these workings to the Portuguese of the seven- teenth century. The valley is not considered healthful, but Barber- ton, the chief settlement, enjoys a salubrious climate. The lowest strata in the valley are a series of soft gray argillaceous shales, greatly tilted by volcanic action. ese seem to correspond wit the Silurian, and in the Drakensberg are overlaid by Devonian strata. KUND AND TAPPENBECK’s EXPEDITION TO THE CAMEROONS. —Among the results of the above expedition are q), the knowledge that the Beundo and Great Njong rivers have their sources above the cataract region ; (2), that the water-parting between the rivers that discharge on the coast, and those that flow into the Congo basin oes not lie near the Cameroons coast, as was previously supposed ; (3), that the water-parting between the left tributaries of the Binue and the rivers which water the German Cameroons region also lies far into the interior; (4), that the racial parting between the Bantu and Sudan negroes does not lie in the direction of Adamawa, but runs in a southerly direction, and is formed by the Aannaga a Great Njong River, and lies about 145 miles from the coast; an 5), that volcanic formations do not occur in the mountains ee iately north of the Zannaga, nor in the region between 1t, and the coast. The Beundo River discharges at Little Batanga, and is known in the interior as the Njong or Nlong, while the Great Njong dis- charges at Malimba by the Borea and Bornu mouths, and mto ; Cameroons River by the Quaqua mouth. A profile accompanymg the repért shows a coast plain about seventy feet above the pat succeeded by a sharp slope rising to a height of 3,000 to 4,000 above sea-level (the Crystal Mountains), beyond which the egos slopes gently to about 2,300 feet. Both rivers have a second pa aract region in the interior, with a long stretch of navigable wat of between it and the lower cataracts, The Zannaga no doubt cart off the water of a great river region.

Parsone, for many years been dry, and though pools occur here and there in the in- terior, and a stream is sometimes formed after heavy rains, no water ever appears on the surface at its mouth. Yet an anchor with a heavy wooden stock has been found embedded in the ancient channel about twenty miles from the mouth. The sandstone cliffs of the coast table-land sink into the valley at about ten miles north of the port, which is larger and has a better depth of water than that of Loanda, from which it is distant 385 miles. The o Valley is fertile, and has some low-growing trees, but the rest of the country near the town is barren, and the want of roads and carriers hampers the trade with the interior.

Mt. St. Michael is a phonolite peak 385 feet high. The Peak (El Pica), is a huge mass of columnar phonolite, with a talus or débris around it. Two other phonolitic masses stand like bastions on the south coast, separated by a ridge of basalt. As the group is surrounded by deep sea, and nothing voleanic occurs near it, Mr. Lea is inclined to think that it marks the site of an isolated vent. The islets of the southern coast are, with one exception, composed of phonolite. Where the phonolite and basalt join, both, especially the former, are more or less disor- ganized in structure. The Sapate, or southwestern heights of the main island, are basaltic. Three-quarters of the insects taken by the expedition were new to science, and of the three reptiles an amphisbzena and a lizard are peculiar, as are two of the three land- birds. About 200 species of plants were found, some thirty, of which were peculiar. Invading plants have mastered the plains, and are gaining the heights and the sea-shore. On the East Hills were found two scrambling bushes of a strange plant which seemed to be the last of their race. Few of the native plants have conspi- cuous flowers, and many are berry-bearing shrubs, Euphorbiaceae, and grasses. But the flora includes a new dodder, an endemic fig, and two species of Oxalis, also a new Convolvulus. Out of the human population of rather over 2,000, about 1,400 are convicts.

As this does not include foreigners peme decreases with each successive year. In 1887 the total number 0 births was 60,666, and the excess over deaths only 5,820.

He admits three genera of Ichthyosauria, viz.: Ophthalmosaurus Seeley (Baptanodon Marsh), Ichthyosaurus Conyb, and Mizxosaurus Baur. He does not find any reason to subdivide the genus Ichthyosaurus. Of Plesiosauride he admits the genera Plesiosaurus, Thaumato- saurus, Pliosaurus, and Elasmosaurus (under the name Cimolia- saurus), but does not include in the last named the Jurassic species which have the same structure of the shoulder-girdle, which Seeley described under the name of Colymbosaurus several years ago. We find this course inconsistent, and believe the principles adopted by Seeley in his classification of the Plesiosauride to be well founded, except as to the genus Murenosaurus, which Mr. Lydek- ker shows to be a synonym of Colymbosaurus. Mr. Lydekker falls into the error of supposing that the genus Polycotylus is princi- pally characterized by the cupping of the vertebre. The fact is, that the structure of the paddles is as different from that of Plesio- saurus, as that of Ichthyosaurus is from Mixosaurus, and in much the same way. 7 with most taxonomists, which we have stated elsewhere. We wi content ourselves now with observing that we find the method of Mr. Lydekker a matter of inconvenience rather than of convenience. We must also once more protest against being misquoted by Mr. ns pt. i., pl. ii. In this instance the head has been placed at the extremity of the tail,” ete., etc. On this I must observe that no such plate appears in the Transactions of the American Philoso- phical Society, or in those of any other Society. Of this Mr. Lydekker can easily satisfy himself. It is true, however, that an error got into the first descriptions of that species (see Proceed. Boston Society Nat. History, 1869-70), but it was done in imitation of the precedent laid down by the describer of the species named Cimoliasaurus (a name which Mr. Lydekker wishes to ach several years earlier. Here the cervical vertebre were descri as caudals. This mistake was corrected by its author after an inspection of the skeleton of Elasmosaurus. The plates and descrip- tions published by the American Philosophical Society are correct, and the genus Elasmosaurus is there for the first time fully characterized. The supposed genus Cimoliasaurus was never aracterized by the author of the name. 726 General Notes. We suspect that if we were to state that Mr. Lydekker had described the bones of a crocodile as those of an ostrich, and the teeth of a baboon as those of an ape, without at the same time stating that he had himself corrected those errors, he would not consider our method of criticism legitimate. And if we were to assert that in description he called the inside the outside, when he had not done so, and stated that a scientific body had published a plate which it did not publish, he would consider re wanting in a primary essential of criticism, viz., accuracy.—E.

Conrad’s “ Fossil Shells of the Tertiary Formations” and “ Fossils of the Tertiary Formations,” I have found that nearly all of them in some respects are deficient. In fact, I have not seen a single copy that gives perfectly all that has been published in the way in which it had been issued, and one finds in the literature quite a number of assertions which show an erroneous or imper- fect knowledge of these two works.! For this reason I consider 1t desirable to give the following notes :— a. 1, “ Fossil Shells of the Tertiary Formations of North ere The two most complete copies which I have seen are those in the library of the Academy of Natural Sciences and my own.

The following notes are also based on the copy in thelibrary of the Academy of Natural Sciences and my own copy, which supplement each other. The introduction is numbered V.to XVI.; the rest is numbered 1 to 89. There are forty-nine plates; some of them are without a number. The book has been issued apparently in three parts The cover of the second part contains quite a number of descriptions. Part I. Pages 1 to 32, plates 1to17. The brown cover is without a date, and gives the title: “ Fossils of the Medial Tertiary of the United States.” The fourth page contains the descriptions of four species. _ Part II.

The other three pages contain quite a number of descriptions, among them the FR four species, which are described on the cover of art L. Part III. Contains apparently the rest of the book : pages 57 to 89, plates 30 to 49. The brown cover is also without date, but gives the title: “ Fossils of the Miocene Formation of the United States.” Regarding the date of issue of the different parts of the “ Fossil Shells,” and the authorship of Part III. and Part IV., nothing need be said here. Regarding the date of issue of the “ Tertiary Fossils,” the following may be stated :— 5 The cover of Part I. of the Academy’s copy bears in Conrad’s handwriting the date “ January, 1838.” Lee The cover of Part II. of my copy is marked with ink in Conrad’s handwriting, “ May 7, 1840.” The cover of Part III. of my copy is marked in the same way by Conrad, “ January 1845.” — Otto Meyer, Ph.D. 728 General Notes. CHALICOTHERIUM AND MacrorHertum.—M. Henri Filhol has recently made a discovery of remarkable interest in the beds of Sansan, of the middle Miocene of France. It removes, in the first this is a well-marked perissodactylic type, closely resembling that of Palsosyops, in the tarsus, especially. er an examination of the feet in the collection of the Jardin des Plantes, no doubt re- mained in my mind of the association of Chalicotherium and Macrotherium. Without anticipating M. Filhol’s' memoir I may note a few of the Perissodactyle characters of the tarsus. The calcaneum has a long neck and broad internal extension, which 1s lacking in the edentates, for articulation with the astragalus. The latter bone is much like that of some species of Aphelops with the neck very short; it has a broad facet for the cuboid. The cuboid has a postero-internal extension which is also found in Paleosyops. The cuneiform is very highly modified, being re- duced anteriorly toathin shell. The third metatarsal abuts against the cuboid, the second against the external cuneiform. In short, remove the phalanges, widen the navicular, and lengthen the nie instead of the second metatarsal and you have a true Perissodacty/¢ tarsus. The carpus is equally so, but is much less characteristic. Turning to the skull, we find of course the teeth of the Palæosyops type. I think there is an alisphenoid canal. There are other non- perissodactyle characters; there is no third trochanter of the fem- urand, as M. Filhol points out the arrangement of the skull 1s very different. The tympanic bones are also largely develope a of a unique shape. The question remains, what is this amıma Geology and Paleontology. 729 M. Filhol’s restoration showing the long fore limbs and short hind . limbs, and feet resting partly on the side, demonstrates that it had the habits of the sloths. He also informs me that the older indi- viduals retain only one incisor. On the other hand the structure of the carpus, tarsus, skull and teeth, is in so many features so strik- ingly Perissodactyl, that there seems to be no alternative except to leave Chalicotherium in this order and regard it as an aberrant form, with nearest affinities to Paleosyops and genera of that line.— Henry F. Osborn, Paris, September Ist. GEOLOGICAL News.—GENERAL.—Mr. Mellard Reade and Mr. Davison have recently pointed out that, owing to the cooling and contraction of the earth, there is at some depth beneath the surface a zone of no stress, that is to say, where the compressive stress due to the radial contraction of the sphere, and the tensile stress due to the circumferential contraction of each zone, are equal. Prof. C. L. Morgan (Geol, Mag., 1888, p. 296) asks, “Is it not possible that throughout the zone of maximum tension, due to circumfer- ential contraction, the rocks may be rendered fluid by relief of CAMBRIAN AND SILURIAN.—The Paleontological Department of the Swedish State Museum has published a list of the Cambrian and Lower Silurian faunas of that country, by Prof. G. Lindstrom, and another of the Mesozoic fauna, by Prof. B. Lundgren. The Cambrian is divided into (1) the Eophyton and Fucoid Sandstones, (2) the Paradoxides beds, (3) the Olenus Schists, and (4) the Dic- tyonema Slate. One hundred and fourteen species are enumera om this formation. The Lower Silurian comprises 1, Ceratopyge Limestone ; 2, Lower Graptolite Schists; 3, Orthoceratite Lime- stone; 4, Middle Graptolite Schists; 5, Chasmops Limestone; 6, Trinucleus Schists ; 7, Brachiopod Schists ; 8, Upper Graptolite ists; and 9x9, Leptena Limestona. The species enumerated from the Lower Silurian number 627. CaRBONIFEROUS.—It appears that the peculiar rock called chert Consists mainly of the spicules of sponges. Dr. G. J. Hinde has found it to be thus composed in the Yoredale series of Yorkshire (Eng.), in Wales and in Ireland, while in the June issue of the Geological Magazine he describes the character of the sponges of the chert and siliceous schists of Spitzbergen. The Permo-Carbonifer- 730 General Notes. ous series of the west and southwest shores of Spitzbergen is over 200 m. in thickness, and is divided by Dr. Nathorst into the Ursa Sandstone, regarded as Devonian, the Cyathophyllum Limestone, the Spirifer Limestone, and the Productus Chert. This series is not followed by grits, sandstones, and coal-measures, but by shales, marls, and sandstones containing an exclusively Permian fauna, an the series itself, though as a whole regarded as stratigraphically equivalent to the Carboniferous Limestone, contains a certain mixture of Permian fossils. The Productus-chert consists of beds of chert composed largely of disintegrated siliceous sponges, but rich also in Producti and other calcareous fossils, and of intercalate siliceous beds consisting of minute grains of quartz, but rich in sponge spicules. The cherty rocks, unlike those of Yorkshire and North Wales, have yielded entire forms of sponges, which have been described by Dr. E. von Dunikowski. Dr. R. H. Traquair (Geol. Mag., 1888, pp. 251-254) describes three new species of Palzeoniscide from the English Coal-Measures. The article is the second contribution from Dr. Traquair upon this subject, the first being contained in the December issue of the same magazine for the year 1886. In the July issue of the Geological Magazine Mr. A. C. Seward comes to the support of Prof. Williamson’s remark that the specific names and definitions of Calamites are probably worthless, bie figure and description of a specimen which upon one side shows P e characters of C. undulatus, while the other side of the same cylinder has narrow and equal ribs. Dr. Schweinfurth has discovered Lower Carboniferous a af the Arabah valley of Upper Egypt, opening out into the Gul ne Suez. He recognizes the identity of the beds he describes wit those of the Wadi Nasb in the Sinaitic Peninsula; the genera are In most cases identical, and the species characteristically Carboniferous. Mesozo1c.—Of the lower portions of the Mesozoic serios oot the Rhaetic and Liassic strata are developed in Sweden, p si more than twenty-four species are enumerated by Prof. meee from the formet and 129 from the latter group. There = hisha wide gap in the middle portion of the Mesozoic, until the raii members of the Cretaceous are reached. These are highly iferous, the list comprising 456 species. Jurassic.—Mr. R. Lydekker (Geol. Mag., 1888, p. 309) ger the genera of Ichthyopterygia to three, viz.: Ophtha n j chthyosaurus, and Mixosaurus, the last the least specialized. Geology and Paleontology. 731 tenuirostris and its allies are the forms most nearly allied to Mixo- saurus Baur, and J. tenuirostris has only four digits. From this Mr. Lydekker agrees with Dr. Baur that the Ichthyosaurs have descended from a tetradactylate ancestor. Two additional species, . cantabrigensis and I. conybeari, are described, the former from the Greensand of Cambridge (Eng.), the latter from the Lower Lias. “The Insect-world of the Lithographic Shales of Bavaria” is the title of an extended article in Volume 34 of Paleontographica, by P. Oppenheim. Among the fossils described are Cyrtophyllites rogeri, a new genus and species of Locustide, two new species of Ephemera, Prolystra lithographica, Eucicada microcephala, Ischy- opteron suprajurense, n. gen. et sp.; Halometra, a new genus of Hydrometride, with two species; three species of Carabide, a Prodytiscus, two forms of Lamellicornia, two of Clavicornia, three of Sternoxia, one of Rhynchophora, and three of Chrysomelide. Creracreous.—A. S. Woodward (P. Z. 8., X. Feb. 21, 1888) shows that the lateral line of Scyllium sahelalme, from the chalk of t. Lebanon, was supported by a series of half-rings, exactly like those met with in Squaloraja and the Chimeroids. The canal of the lateral line was ss presumably an open groove; a condition which obtains in only two living Selachians, Echinorhinus and Chlamydoselachus. Squatina eranei is the name given by Mr. S. Woodward to a species of “angel-fish” discovered in the chalk of England, and distinguishable from the species of Squatina already satisfactorily nown by the great relative size of the spinous dermal tubercles. No defences of this kind have been found in extinct forms, and the ne species has them much smaller in proportion to the size of e fish. The same geologist also describes certain specimens of mandibles of the singular Belonostomus cinctus, revealing the precise character of the dentition, and the relations of the bones. The two rami occupy only half the entire length of the jaw, the anterior half being formed by the enormously elongated pre-symphysial bone. The narrow and deep rami meet at a very acute angle; the sym- physis is elongate, gradually diminishing to a thin edge below, and the large pre-symphysial bone, which is a median unpaired element is articulated to the sloping triangular surface thus formed. On the latter bone there is a median row of about thirty large conical teeth, while a great number of smaller similar teeth—the largest little more than one-sixth the height of the largest of the median series— are placed irregularly upon the lateral margins of the bone. 732 General Notes. MINERALOGY AND PETROGRAPHY.' the Archean rocks of Missouri. In a diabase porphyrite, from Madison county, are areas of quartz, which seem to be the remains of porphyritic crystals, whose original outlines have been pene by the corroding action of the diabase magma before its consolida- tion. Since an analysis of the rock reveals a content of only 53.47 of silica, it would seem that we have another instance illustrating the possibility of the separation of free silica from a very _— magma. In another porphyrite the rare rock constituent pieta tite was detected. A very instructive fact in connection giri a Missouri rocks is the existence of granites of idiomorphic seers crystals which have been enlarged by the addition of orthoe e material.

He explains the ori- gin of the zinc by supposing the biotite to have been acted upon by the remainder of the liquid magma, from which it had sepa- rated, and thus to have lost a portion of its alkaline and alkaline- earth constituents, which helped to form the feldspar, forming with small plates of biotite the entire groundmass of the rock. The iron left by this decomposition separated out as magnetite in the dark zine——In a late number of the American Journal of Science Mr. Kemp’ describes a dyke of camptonite cutting the rocks in the Forest of Dean magnetite mine in Orange county, N. Y. The rock differs from the typical? camptonite in containing a larger proportion of feldspar and smaller crystals of hornblende. The feldspar is an oligoclase with the composition :— Si 1810 Te’ IS Ges 1 LU 89 2a — While engaged in studying a peridotite from Little Deer Isle, in Maine, Mr. Merrill? noticed the enlargement of its augitic consti- tuents by the growth around it of a secondary augite with the same optical orientation, but a different color. MINERALOGICAL News.—In a very interesting paper on the chemical constitution of the different colored micas occurring in a pegmatite at Schüttenhofen, Bohemia, Scharizer* records the analy- ses of several members of the mica group of minerals, and draws some general conclusions in regard to them. The pegmatite is sur- rounded on all sides by limestone. Its constituents are pairs 2 in three zones, in the first of which lepidomelane and white and brown muscovite occur.

Botany. 737 BOTANY.: THE GENUS TAPHRINA OF TULANE.—This genus (Ezoascus of Fuckel) of curiously simplified Ascomycetes, is an interesting one for the comparative anatomist, affording as it does such a remark- able instance of structural degradation through parasitism. 2B Winter (Krypt-Flora v. Deutschland, Oesterreich u. d. Schweiz. 1* Band, 2 Abth., pp. 2-11) the genus was made the principal one of the first order (Gymnoascex) of the class Ascomycetes. | He divided the Gymnoascew into two families, viz.: (1) Exoasci and (2) Gymnoasci, the first including the genus under consideration (under Fuckel’s name, Exoascus), and the second, the related gen- era, Endomyces, Eremascus, Gymnoascus and Ctenomyces. e extreme simplicity of these plants, composed as they are of little more than single parasitic asci, marks to a great extent their relationship to the larger Ascomycetes. Parasitism has here brought about an almost complete atrophy of the plant body, as in the vine rapes (Rafflesiacee), among the parasitic Phanerogams the plant body is almost entirely suppressed, leaving only the large flower bud which grows directly from its hort. ‘ The genus has been recently made the object of study by a Swedish student, C. J. Johanson of MS esa who has distinguished twenty-one Scandinavian species, as follows :— Taphrina pruni Tul. (Exoaseus pruni Fkl.). ia ‘tues Tul.

In his introduction the author says that “the demand for information concerning these plants is so pressing that it is thought but to issue the first part ot the work now, to be followed in a year or two by the second part, which will contain descriptions of the species now known to inhabit American waters.” The part before us contains (1) an Introduction, mainly devoted to collection, preservation, habitat, etc., (2) a chapter principally con- sisting of structural details, with a brief historical statement. In this, the term sporophydium is introduced for the spore-fruit or spo- rocarp. We prefer the term sporocarp, and regret that our author did not adopt it rather than the other.

Herdman communicates to Nature an account of experiments made with the electric light in marine collecting, from which we make the following extracts: A sixty-candle power Edison-Swan submarine light was arranged in the mouth of a tow-net, and the whole lowered to a depth of three fathoms and allowed to remain there for half an hour. Another similar net, but without illumi- nation, was lowered on the opposite side of the ship to the same depth and for the same length of time. When hauled to the surface the dark net contained practically nothing, while the other held an abundant gathering, consisting chiefly of Crustacea. Another test was made, both nets being lowered to the bottom (six fathoms), and with similar results. It was noted that the Amphipods taken with the light in the deep net appeared to be mostly red-eyed species. If on detailed examination this is confirmed, it may indicate an interesting relation between the color of the eyes and sensitiveness to the electric light. Tue Fauna OF THE SUEZ Canau.—Dr. E. von Martens exhibi- ted at a meeting of the Berlin Gesellschaft Naturforschender Freunde (Stzber. 1887) a collection of shells made in the Suez Canal, and made some remarks upon the origin of the fauna of the Canal. Collating all known observations, he found that of twenty-seven species of molluscs found in the Canal, nine came from the Medi- terranean and eighteen from the Red Sea. An examination of the fishes showed a similar condition. Of sixteen species reported from the Canal, six were from the Mediterranean and ten from the Red Sea side. The distribution of the species in the different parts of the Canal is shown by tables; and a glance at these clearly indicates that the admixture of faune is far from complete. BRAIN or Ceratopus.—In a paper (Proe. Roy. Soc’y., XLIII.) Mr, Alfred Sanders concludes that the brain of Ceradotus presents an embryonic condition in three respects, viz.: first, in the extreme size of the ventricles and in the tenuity of the substance of their walls ; second, in the alternating origins of the dorsal and ventral roots ; third, in the fact that the origins of the dorsal roots are close to the central line. Compared to Protopterus, it differs in the shape and the imperfection of the cerebral lobes, and in the fact of its having a well-developed rhinencephalon ; but it agrees in the nar- rowness of the thalamencephalon and mesencephalon, and in the breadth of the medulla oblongata, as also in the rudimentary char- acter of the cerebellum. Ceratodus agrees also with the ganoids in the comparative narrowness of the mesencephalon and in the pro- portions of the cerebellum. With the Plagiostomes it agrees in the structure of the optic lobes, both orders presenting a large ganglion 742 General Notes. of large cells in the dorsal part. With the Teleostei it agrees in the multi-axial fibres which, a short distance anterior to its termination, resemble Mauthner’s fibres, also in the position and fact of their decussation. With Petromyzon it agrees in the structure of the tela choroidea, which covers the fourth ventricle. Deep Sea Fisues.—Not less than 3800 specimens of deep-sea fishes were dredged in the last voyage of the Talisman. At the dredging No. CX., as many as 931 were captured, of which 780 were EHymenocephalus italicus Giglioli. The truly deep-sea fishes, says M. L. Vaillant, belong to the Gunther and others, raise the known species of this se ee fifteen. Most of these fishes have the dorsal and anal fins ; ro h back upon the caudal peduncle, and seem adapted for easy and rap locomotion.

Bathysaurus, Halosaurus, Bathypterois, Macrurus, Coryphenoides, and many other genera are found both in the Atlantic and in the Pacific, and many species seem to have an extensive distribution. Thus Dicrolene introniger occurs near the North American coas and on those of the Soudan; Macrurus holotrachys Gunt., dis- covered at the mouth of the La Plata, has been dredged on the Maroccan coast; Stomias boa ‘of the Mediterranean has been taken in the Arctic Ocean, in the Atlantic, and in the Pacific; and the Talisman captured at the Azores, off the Soudan, and at the Cape erde Islands, a Macrurid which seems to be Macrurus juponicus eg. VACUITIES IN THE SKULLS oF Mammats.—Dr. D. D. Slade presents (Bulletin Mus. Comp. Zoology, XIII., 8) a comparative study of certain vacuities found in the macerated mammalian skull. , THE TEETH or SHErp.—Miss Florence Mayo has recently investigated (Bulletin Mus. Comp. Zool., xiii.) the question as to whether at any stage of development there occur germs of the superior canines and incisors in the sheep, a question upon which there were conflicting opinions. She finds that at a certain stage in the development of the embryo sheep the dental lamina exists throughout the incisor and canine regions and that in the latter an enamel organ is formed but nowhere is there a dentine germ. No enamel is ever formed and the organ soon disappears. From the standpoint of phylogeny Miss Mayo thinks that the disappearance of the teeth has been a progressive one, beginning with the middle incisors and gradually extending back. This has already been shown by palæontology. 744 General Notes. LocaL VARIATIONS IN THE COLORS OF A FEW NEBRASKA FLYING SQUIRRELS.—Coues and Allen, pp. 656-661, Monographs of North America Rodentia, published in 1877, being Vol. XI. of Hayden’s Report of the United States Geological Survey of the Territories, state that: “The American Flying Squirrel, (Sciuropterus volucella), presents a range of geographical variation in size quite unparalleled in other members of the Sciuride, and only equaled in some species of the Canide, and possibly in Cervus virginianus. On the other hand the coloration is remarkably constant, almost exceptionally 80. * * Specimens from the same locality sometimes differ in the color of the dorsal surface as much as do the most diverse examples from widely separated localities.” : e local variations in color are well illustrated by five specimens before the writer, viz:— hot | eee No.| When collected.)

Number five was a very unusual specimen, both in color and in the arrangement of the color. Mr. W. B. Harmon, who collected this specimen, states that four other squirrels were found in the nest with this one, number two being one. The other two appeared to be similar to number two in color. Besides the measurements and the dusky spot in front of the eye, ordinarily, were obsolete, he pelage on the upper surface of the body was of the same color to the base. The only black or dark hairs visible were the mus- taches, which were black. The hair has the appearance of being in a healthy condition, and the specimen is rather above the average size. This specimen is undoubtedly an extreme case of color variation. _ Habitat, near Nebraska City, Nebraska, on the Missouri river, in latitude about 40° 30, , It might be well to notice that the average measurements given in this article are about the same given by Coues and Allen for S. volucella var. hudsonius, which is stated to exist “ mostly north of the parallel of 49°; average measurements of var. volucella, the southern variety, being much less.— W.

Soc., Edin., xxxiii.) the structure of the sponge Sub- erites somuncula. The study was rendered difficult from the pres- ence of large numbers of silicious spicules. Theciliated chambers are small, and are in connection with the canal system, the afferent and efferent canals lying side by side. The canal system is of what is known as the fourth degree of complexity. In the same paper are noti uliar club-shaped prominences on the surface of Spongelia the function of which is problematical. These knobs 746 General Notes. have a well-developed ectoderm, the centre being occupied by a compact and intricate network of fine filaments, the meshes of which were occupied by cells of varied size. Similar structures, it may be noted, occur in several American sponges. Ca:LENTERATA.—G. H. Fowler describes (Proc. Zool. Soc., 1888), a new Pennatula (P. bellissima) from the Bahamas. In its systematic position it stands nearest P. naresit. Prof. A. M. Marshall monographs the Pennatulids collected by the “ Porcupine” in the Trans Roy. Soc., Edin., xxxiii.

Giglioli, of the Royal Museum of Florence, records (Nature, XXXVIII., 103) the receipt of the sixth known specimen of the rare Lepidosiren paradoxa, which for many years was only represented by Natterer’s original specimens. The present individual was taken at Antaz, near the Madeira River, in Septem- ber, 1887, and when received was in a state of incipient decomposi- tion. Mr. G. B. Howes communicates a note on the same subject (Le., p. 126), calling attention to the specimen recorded by Bibron and Milne-Edwards in 1840. Professor C. T. Lutken has recently ( Vidensk. Selsk. Skr. Kjob., IV.) described the skeleton and some other parts of the deep-sea toad-fish Himantolophus. Comparisons are made with Ceratias. According to Prof. D. S. Jordan ‘and B. W. Evermann, there are about 150 species of fishes known in the waters of Indiana, and about fifty of these may be regarded as food-fishes. Of the remaining kinds, some ten are large enough for food, but for one reason or another are not used. The flesh of the paddle- fish and shovel-nosed sturgeon is poor and tough, that of the gar- pikes is not eatable, while the hickory shad and skip-jack are valueless on account of their dry thin flesh, full of small bones. he cisco of the deep lakes of Northern Indiana and Wisconsin, formerly thought by Prof. Jordan to be distinct from the leak herring, and named by him Argyrosomus sisco, is now held by, the same authority to be only a local variety of Coregonus artedi modi- fied by residence in the smaller lakes. „Dr. A. Gunther (Ann. and Mag. Nat. Hist., June, 1888) describes nine new species of fishes from the Yangtsze-kiang, collected at or near Ichang, One of these, Eleotris zanthi, belongs to the spine- finned section, the others are Cyprinide or Cobitidina. I. R. Storms has, in an article in the Annals and Magazine of Nat. Hist, for J uly last, attempted to solve the questions pertaining to the structure and morphology of the disk of the remora. e disk is a modified spinous dorsal, and not of dermal origin, he believes to be proved : (1), by its position; (2), by the slight trans- formation of the interneural spines; (3), by the presence of the changed, yet recognizable elements of a normal spinous dorsal fin. A typical segment of the spinous dorsal of Scomber has three 748 General Notes. elements: (1), an interneural spine ; (2), an intercalary bone (or aseost) which has the shape of two wings; and (3), a spinous ray. A division of the disk of Echeneis has also three elements; the lower extremities of the interneutrals point backwards instead of forwards; the intercalary bone is formed of wing-like plates, and the spinous ray is represented by a pair of pectinated lamelle joined in the median line and occupying the whole surface of the disk. The upper expanded portions of the interneural spines each carry a pair of lamelle. The wing-like plates of the intercalary bone are connected by a narrow portion which expands in the middle and rests partly on the interneurals, and the wing-like parts of the. consecutive intercalary bones overlap one another like the tiles of a house. The pectinated lamelle are discovered by M. Storms as transversely enlarged spines, and he believes that the bases of the spines alone have formed the lamellæ, and that the spine proper was gradually reduced until it has nearly disappeared. e rows of small teeth which cover the posterior margins of the lamelle are by M. Storms thought to be of dermal origin. That they are not formed by outgrowth of the bone is proved by the facility with which they fall off by prolonged maceration. ‘The fossil Hehenew glaronensis, the disk of which extends only on to the posterior part of the head, instead of covering its whole surface, seems to support our author’s supposition that the disk was originally formed on the dorsal region, and has migrated gradually to its present position. REPTILES AND Barracuta.—Dr. O. P. Hay’s list of Amphibia and Reptilia at present known to occur in the State of Indiana includes seventy-seven species, twenty-seven of which are Batra- chia. ; Dr. A.

Paul Sarasin describes the lateral organs of the larva of the Ceylonese cecilian as related to auditory organs of the inver- tebrate type. According to Nature, a communication from Mr. George A.

Brrps.—Dr. Emin Pasha has recently forwarded to the London Natural History Museum, two collections of birds, the first, com- prising 114 forms, from the Wadelai district, between 2° and 5° N. Lat., and 31° and 33° E. Long., while the other, consisting of i mns, is from the Tingasi district, westward of 31° E. Long. In the latter collection there is not a single East-African form, while in the former thirty-three forms belonging to the fauna of E. and N Africa occur. It is thus evident that on the features of the West-African river-system. Mr. Thomas attributes e abruptness of the change of fauna, exhibited both by mammals 750 General Notes. and birds, to the sudden ending of the great West-African forest." Five previous papers, by Drs. von Pelzeln and Hartlaub, have described former ornithological collections sent to Europe by Emin Pasha, so that it is not to be wondered at that this, the first consign- ment received at London, contains only four new species. Mammats.—In three papers (Proc. Amer. Philos. Soc’y, XXV.) Professor T. B. Stowell describes the glosso-pharyngeal, accessory, and hypoglossal nerves in the domestic cat. Three plates of diagrams illustrate the accounts. At the meeting of the Royal Society of Edinburgh, May 7, 1888, Dr. Alexander Bruce described a case of absence of the corpus cal- losum in the human brain. The skeleton of a second specimen of Swedenborg’s whale (Buba- lena swedenborgii) has been discovered in Norway. It is said that the original specimen was discovered in the early part of the last century in Gothland, and that the bones were regarded as those of Dr. A. Nehring criticises (Stz. Gesell. Naturf.

A New ENTOMOLOGICAL JouRNAL.—The first number of an entomological journal bearing the title Insect Life has just been sent out from the Division of Entomology of the United States Department of Agriculture. This journal is “devoted to the economy and life-habits of insects,—especially in their relations to agriculture,—and is edited by the entomologist and his assistants, with the sanction of the Commissioner of Agriculture.” We are glad to welcome this periodical, for we believe it will be an exceed- ingly useful one. As the writer knows from personal experience, entomologist, and is buried there simply because the individual items do not seem of sufficient importance to be published in the a pages 0 t Life will form an appropriate receptacle for all data of this kind. It will, also, enable the entomologist to publish promptly matter of ephemeral interest which would lose its value if kept for the annual report. the initial number.

In four ' This department is edited by Professor J. H. Comstock, Cornell University Ithaca, N. Y., to whom communications, books for notice, ete., shouid be sent, 752 General Notes. cases the description is based upon a single specimen; in the fifth upon but three. The species are from Utah, Colorado, and Nevada county, California. Although the descriptions appear to be very carefully written, and doubtless are excellent ones if it is possible to prepare good descriptions of species from unique examples, still, what is the occasion for publishing these descriptions here? Is it not about time that the serious workers in entomology should abandon the practice of publishing isolated descriptions except where there is a necessity for the description ; as, for examples, in articles describing the life-habits of the species in question? We can see the reason for the description of Lestophomus iceryed, a parasite of cottony cushion scale which has been artificially intro- duced into California from Australia. 3 : In form Insect Life has the appearance of the bulletins which have been sent out by the Division of Entomology, the size of the page and the type being the same. It is to be published on an average once a month, but will not have the regularity of a regular monthly. PREVENTION OF CuRCULIO INJURY TO CHERRIES BY AR- SENICAL Porsons.—During the last two years we have heard it repeatedly asserted by fruit growers that curculio injury can be largely prevented by spraying the trees with Paris green or London purple. At first we were incredulous ; but the statement has been made so positively that we have said in reply to inquiries that 1t might be so but that we could not say in what way the poison acted, as the eggs of the curculio are laid beneath the surface of the fruit and out of the way of anything which might be sprayed upon the tree. We are glad to see that Mr. Clarence M. Weed has begun his work as Entomologist to the Ohio Agriculture Experi- ment Station by conducting careful experiments on this subject. The results are very striking. They seem to show so far as the results of a single season’s work with a single variety of cherries can be relied upon: “ That three-fourths of the cherries liable to my by the plum Curculio can be saved by two or three lo o London purple in a water spray(in the proportion of one ounce to HV? gallons of water) made soon after the blossoms fall.” wo quarts of cherries from each of the lots experimented on wet chemically examined at the time of ripening by Professor H. Weber and showed no trace of arsenic. + hia No explanation is made by Mr. Weed as to the way m W re the poison acts. Whether the adult beetles are destroyed be ni they lay their eggs or whether the poison reaches the young larvæ. Entomology. 753 Report or THE U. S. Enromotocist.—The annual report of the U. S. Agricultural Department has just come to hand. The report of the Entomologist, although containing less original material than some of the preceding ones, is a valuable one to agriculturists. The principal articles are one upon the Chinch-bug and one upon the Codlin-moth. These were prepared by Mr. Howard, and con- sist in each case of a résumé of the natural history of the insect and of the more important remedial measures. Although these articles contain little that is new, they will be very useful to agri- culturists, as they render accessible information not easily obtained outside of an entomological library. In addition to these two articles the report consists of reports of special agents. The most striking of these is the one by Mr. D. W. Coquillett on The Gas Treatment for Scale Insects. One of the principal discoveries made by Mr. Coquillett is that hydrocyanie acid gas when passed through sulphuric acid is rendered harmless to the foliage of trees confined in it. This will greatly lessen the cost and labor of treating trees with this gas. The report is illustrated with figures of portable tents pair are used for enclosing the trees while they are being treated. us flabius, Formica, schonfussii, F. fusca, are not in the least responsible for their distribution over the fields.

American Naturalist, Vol. xxi., pp. 382-579. 754 General Notes. EMBRYOLOGY .! OBSERVATIONS ON THE DEVELOPMENT OF CEPHALOPODS.’— In this memoir Mr. S. Watase deals very fully with the origin of the cells which give rise to the yolk membrane. With the excep- tion of Lankester, all authorities agree in describing the “ yolk membrane” as originating from the segmentation of the original germinal disk. As to the origin of the digestive tract, Kölliker and Bruce describe the digestive tract as continuous with the “yolk membrane.” Balfour and Lankester derive the “ mesenteron” from the lower layer of the mesoderm; Metschinikoff derives the major part of it from the ectoderm, while Ussow traces the whole diges- tive tract to the ectodermic involutions, . r. Watase’s conclusions are as follows in regard to these points: (1) The “ yolk membrane” is derived from the original germ disk; es it makes its appearance underneath the marginal zone of the germ disk, near to the junction of the intermediate zone; (3) the cells of the “yolk membrane” are irregular in outline, fusiform 1n cross-section, ameeboid in movement, each with one or more large nuclei; (4) with the growing edge of the blastoderm the under- lying “yolk membrane” keeps pace in growth with the area) germ disk, but never coming outside of the peripheral zone ; (5 the “yolk membrane” grows at the same time from the margin to the centre of the disk, and in time it comes to completely separate 0 the epibolic gastrula; (7) hence Mr. Watase believes the “ yolk membrane” to be necessarily a true endoderm, and its sole repre ee re i Š an mic invaginations, that is, by prolongations of the proctodæum at stomodæum ; (9) at no period of the development does there wee any connection between the “yolk membrane” and the Bpi tract, and long before the absorption of the food yolk is comp the permanent digestive canal is formed ; (10) with = pen of which 1 Edited by Prof. John A.

Embryology. 755 is, like that of the periblast or merocytes in fish ova, for the pur- pose of appropriating the yolk substance. Two admirably drawn colored plates illustrate Mr. Watase’s memoir. DEVELOPMENT OF THE Sra-Bass (Serranus atrarius).—During the early part of the month of July last, in the laboratories of the U. S. Fish Commission, at Wood’s Holl, Mass., the writer had the opportunity to study the development of this form. The eggs are of the floating or pelagic type, and very transparent, measuring very nearly 1 millimetre in diameter. The buoyancy of the egg is no doubt increased by the presence of a moderately large oil drop which is embedded in the yolk, near its periphery, and at the pole nearly opposite the point where the blastoderm is formed. Hatch- ing occurs at the end of the third day, and the oil drop is pushed toward the cephalic end of the yolk, as the latter is nearly absorbed. : The embryos when hatched present much the appearance of the young Tautog or Mackerel, as respects their transparency, but they soon have their pigment spots arranged in a peculiar way along the edges of the median fin folds. Later, the arrangement of the pig- ment cells is somewhat different and more irregular, while a second kind of pale yellow pigment cells appear, forming three pretty well- efined transverse bands, at equidistant intervals, across the body and tail of the young fish.

Mr. Stearns was strongly attracted towards a naturalist’s life. His ambition, however, met with dis- couragement in the absurd statement made by some one in Wash- ington to the effect that no successful work in science would be possible without a classical education. _ In 1880 he was made a special agent of the U.

STEERE. —Epitors NATURALIST :— Not long since I passed a day at Ward and Howell’s Natural History establishment at Rochester, and I was so much interested and surprised, that I have thought that some of the readers of the NATURALIST would be glad to know more of this, the most extensive establishment of its kind in the world, I had bought several thousand dollars worth of specimens of various kinds from Ward and Howell in fitting up the museum of the School of Mines and I had found it a great help to be able to obtain at a fair price authentic, reliable material needed to illus- trate lectures upon geology and natural history, and not to be procured through any other channel. But until I stopped at Rochester and went through the establishment, I had no conception of the great variety and excellence of the material available for science teaching that was here accessible with the growing interest in scientific studies, and the increasing appreciation of the value of object teaching, that man is a public benefactor who will supply to us at a reasonable cost, all things necessary to illustrate lessons an lectures. This, Ward and Howell can do to a greater degree than any one person, firm or company in the world. This statement may be regarded as an exaggeration, but after considerable experi- ence with the dealers in natural history material abroad, I do not hesitate to repeat it with emphasis. Professor Ward is himself an educated, scientific man, well up in geology, mineralogy and zoology ; he also has a passion for adventure and collecting, which has carried him more nearly “all over the world ” than any one else of whom I have known or heard, After his stock of the more common things was large enough, he gave himself up for years to the search of rarities. For example, some years since an interest was excited in the structure of Hatteria, and many biologists desired to study its pineal eye and other matters connected with its anatomy, but none were to be had; so Professor Ward, as he has often done, organized an expedition to find and obtain the desidera- tum. In this case it was necessary to search for long distances along the coast of New Zealand before the haunt of this peculiar lizard was reached, and a sufficient number was captured to supply the wants of the museums of Europe and America. ge fe and his assistants have scoured India, Borneo, Africa an South America for rarities and always with a degree of thorough- ness and intelligence that secured success. Recently, when a g Scientific News, 763 skeleton and skin of the dugong was needed for the Melbourne Museum, it was found more convenient to get it from Professor Ward than to depend upon the efforts of Australian hunters or naturalists. Ward and Howell have been now for years occupied in efforts to secure the best representatives of all departments of zoology, and in some instances have undertaken to do what no other dealers in of Mammalia gathered for the Museum of Comparative logy at variety beyond the paying demand. No museum in this country as anything like such a display of interesting specimens in all departments of natural science rd and Howell ized or stuffed. Fourth, the department of invertebrate zoology which includes a splendid collection of shells, and a collection of sponges exceeding in volume and interest any other known to me. ifth, the botanical department, which includes the herbarium of the famous Dr. Harvey. In the preceding paragraphs I have spoken simply of Professor Ward or of Ward cad Horal it is but just, however, to Mr. E. E. Howell, to say that he is much more than a mere name in the establishment, He is a trained geologist and was for a long time Connected with the United States Geological Survey. Naturally, he presides over the departments of geology and mineralogy ; his Special interest which is also shared by Professor Ward is meteor- a 764 General Notes. ites, and it has led them to make extraordinary efforts to gather these interesting objects. Efforts which have resulted in by far the finest collection in this country. To those who know little of Ward and Howell they may seem mere traders, and this letter, a puff of a business house, but they are much more than traders, they are co-laborers in the work of scientific education whose assistance many a teacher has recognized with gratitude ; and this letter is an unsolicited appeal to all those inter- ested in the natural sciences to visit an establishment where so much may be learned at so little cost; and to call attention to the vast amount of indispensable material for the museum, the lecture room and the laboratory which Ward and Howell have brought within easy reach and much of which, without their efforts would have been entirely unattainable.

No. 261, SCIENCE-TEACHING IN THE SCHOOLS." BY WM. NORTH RICE. p word “ schools ” is here used in distinction from the higher institutions—colleges, universities and technological institutes. It will be convenient for us further to distinguish the “ high schools ” from the lower schools. As here used, the phrase “ high school ” designates a school whose pupils range from thirteen or fourteen to seventeen or eighteen years of age, and which professes to prepare students for the colleges and scientific schools. _ In considering what should be the course of study in the schools, it is necessary to recognize the distinction in scope and spirit between general and special education. By general education is meant such education as is intended to prepare a person for the duties of manhood or womanhood, irrespective of any particular trade, profession, or station in life. By special education is meant such education as is intended to prepare a person for some particular trade, profession, or station in life. The courses of study in the schools must be, in this sense, general. We are not to try in the schools to make biologists, geologists, nor chemists. We are not to make physicians, nor engineers, nor lawyers, nor clergymen. Very few of the children in the schools will enter any of these Professions ; and, of that few, still fewer are aware of their destiny. But all the children in our schools have the expectation of growing Up to manhood or womanhood. They will take their places in the < Address at the meeting of the American Society of Naturalists, in ew Haven, Conn., December, 1887, by William North Rice. 766 Science-Teaching in the Schools. ranks of those who earn an honorable livelihood by honest labor, or among those whom vice or improvidenee renders a burden to society. Those of one sex, by the possession of the right of suffrage, and those of both sexes, by their share in that informal and un- regulated vote which we call public opinion, will in their degree shape the institutions of the land. Most of them will marry, and, by the direct effect of heredity, and by manifold influences of conscious and unconscious education, will mould the character of future generations. All of them must make individually the momentous pilgrimage through this mortal life to the solemn mysteries beyond, The arrangements of the schools must be adapted to the common needs of humanity, not to the peculiar tastes and conditions of individuals. There must be one course for the children of the rich and the poor, the learned and the igno- rant. Such an average course will not be the best for every cnild, but it will be the best practicable for the great body of children. To employ private tutors, and adapt the educational course to the supposed tastes or needs of each individual child, is impossible for the poci, and generally undesirable for the rich. The advantage to the child from being in a class of reasonable size, feeling the timulus of intellectual competition, and learning the truly demo- cratic lesson that only personal merit can win, is worth (except 1m case of children of feeble health or very peculiar constitution) far more than any advantage which can come from the adaptation © the work of a private tutor to the child’s idiosyncracies. In re to the necessity of a uniform course of study, the high schools fom a partial exception. In the high schools it becomes practically necessary to provide two courses of study—one for those who are preparing for the classical courses in the colleges, the other for those who are preparing for the scientific courses in the colleges and technological schools, or whose schooling is to be finished with the high school. To a limited extent, also, elective studies may be introduced into the high school course. In the past, two theories have been maintained in regard to the proper aim and spirit of a general educational course. The ua plinary theory is that the object of general education is to se the mental faculties, it being assumed that a vigorous and gy disciplined mind is the best preparation for all work that may Science- Teaching in the Schools. 767 required of aman. The practical theory is that the object of educa- cation is to furnish the necessary information for the guidance of one’s conduct in all probable circumstances. Of late it has been recognized that these views are not mutually exclusive, and that a true theory of education must combine the two. The shield is both gold and silver. A right education must be both disciplinary and practical. But this harmonizing of the once hostile theories has not been effected without important modifications of each. On the one hand, the advocates of the disciplinary theory have come to recognize the truth that mental discipline can be obtained not merely from the study of some two or three subjects, but from the study of almost any subject. It is coming to be admitted that, from the disciplinary standpoint, the important question is not what we study, but dow we study. The very same mental faculties may be disci- plined, and disciplined in ways remarkably similar, in dealing with the most widely different subjects. The reasoning by which the comparative philologist traces the evolution of languages is strik- ingly analogous to that by which the comparative anatomist'traces the evolution of organic structures. On the other hand, the advo- cates of the practical theory have been compelled to a broader® and higher view of utility than the merely bread-and-butter view. The individual man is at once body and soul; and he comes into relations with the material universe, with his fellow-men, and with that unseen Power wherein nature and man alike live and move and have their being. Whatever may be known or believed with reasonable probability in regard to the human body, and in regard to the laws of that material universe with which it is related,—in regard to the human mind, whether as self-revealed in conscious- ness, or as indirectly manifested in literature and history—in regard to the Creator, whether made known by the facts of nature, or by a historic revelation—all this aggregate of varied knowledge and belief is in the highest and best sense practical, for it all tends to guide the conduct of life. The claim of any particular branch of study to a more or less prominent position in the curriculum of the schools must accord- ingly be tried by a twofold criterion—its power to afford an effect- ive mental discipline, and the practical utility of the information which it conveys, 768 Seience-Teaching in the Schools. It would be obviously a waste of time to discuss the practical utility of the sciences of nature. In this age of steam and elec- tricity—this age of aniline dyes and anesthetics and antiseptics— this age when science is multiplying comforts and conveniences and amenities, stamping out zymotic diseases, and largely increas- ing the duration of the life which it beatifies and ennobles—no one is so stupid as to deny the utility of scientific knowledge. A few words may with propriety be said in regard to the disci- plinary value of the study of the natural sciences, for in some minds still lingers the superstition that no studies are disciplinary except languages and mathematics. The natural sciences are unique in their power of training the perceptive faculties. When these sciences are rightly taught, the student is brought face to face with natural phenomenon, which he is required to observe and describe. The perceptive faculties are not, indeed, the highest of human faculties, but they are by no means to be despised. A student who has learned to observe and describe correctly so simple a matter as the form of a leaf, has gained a power which will be of lifelong value, whatever may be his sphere of professional employment. If the student is required to write descriptions of observed phenomena, there may be gained incidentally a discipline in perspicuity and precision of expression, which will be of no trifling value. The natural history sciences afford an unrivaled training to the powers of comparison and classification. Sometimes, indeed, these sciences have been called distinctively the classificatory sciences: They have been (at least since the publication of Darwin’s epoch- making work) vastly more than mere classifications. They are truly dynamical sciences, revealing the processes whereby organie nature has attained its present state. But they are nevertheless a very important sense classificatory sciences. In no other class 5 subjects has classification been so minutely elaborated. No studen can learn to marshal the array of species into genera, families, orders, classes, and sub-kingdoms, as men are marshaled ps d companies, regiments, brigades, and divisions of a well-disciplin army, without acquiring a more systematic habit of thought on ze subject which may engage his attention. But the cavont a natural history classification is not the only feature of value m Science-Teaching in the Schools. 769 connection. The student is continually taught to distinguish not only degrees but kinds of resemblance and difference,—to distinguish those features of structure which are adaptive and superficial from those which are typical and fundamental,—to distinguish analogies from homologies. No one can learn to recognize the mammalian character of a whale under the disguise of its fish-like form, or to recognize the crustacean character of a barnacle under the disguise of its oyster-like shell, without becoming in general a sounder thinker, The sciences of nature afford a valuable discipline to the reason- ing faculties. Educators have always endeavored to afford a two- fold training in reasoning—a passive discipline, by requiring the student to familiarize himself with examples of reasoning recorded in the works of great thinkers ; and an active discipline, by submit- ting to the student problems for solution, which, if not new to the human intellect in general, are at least new to the intellect of the particular student. The study of mathematics has always, and deservedly, been highly esteemed for the facilities which it offers for both these kinds of training. But the sciences of nature also have their splendid examples of reasoning. An intelligent study of Darwin’s “ Origin of Species” is perhaps not inferior as a logical praxis to the study of elementary geometry. Indeed, in one respect the former is superior, for the reasoning of natural sciences is more nearly akin than that of mathematics to the reasoning of practical life. And the sciences of nature have their problems in which the reasoning faculties of the student may find an active discipline. Every laboratory experiment should be an exercise in reasoning as well as in observation. A logical interpretation should be required as much as an accurate description of the phenomena. Moreover, the continual inculcation of the doctrine which is the very key- note of science—the doctrine that there is no such thing as chance —that all events are linked together in chains of cause and effect— 1s itself an education in philosophical thinking and in rational acting, Not to be ignored is the influence of the natural sciences on the esthetic nature. There are indeed some scientific men—animated cases of dissecting tools and locomotive microseopes—who can con- template nature without admiring her. But, for most of those 770 Science- Teaching in the Schools. whose attention is attracted to nature, her aspect is multiform, and her speech many-tongued. And the devotee of nature’s truth is ever delighted with the rich stores of nature’s beauty. It is no mere accident that the same generations of mankind that have developed the sciences of nature have developed two new arts— landscape-painting, and the poetry of nature. There is inspiration for the imagination, as well as satisfaction for the understanding, in.the contemplation of that far-reaching reign of law which is at once the fundamental postulate and the crowning induction of sci- ence. The old myth of the music of the spheres is only a parable of the all-pervading harmony of natural law. Nor is the study of science without its wholesome influence upon the moral nature. Science is indeed no patent panacea for human depravity; but no one can become imbued in any measure with the spirit of science—the spirit of unselfish, courageous, reverent truth- seeking—without some degree of moral uplifting. I believe that a comparative study of biography will show that flagrant immorality has been exceedingly rare among scientific men—much rarer than among men of equal intellectual eminence devoted to literature, art, or almost any other pursuit. Literature and art may express and incite the basest passions. Science—truth—is never impure. The claim of natural science to a prominent position m the educational course is now pretty fairly conceded in the higher institutions of learning. ‘The most conservative of the colleges are making liberal provision of instructors and of material facilities for the teaching of the sciences, and the student is required or rae to devote a large share of his time to this class of studies, while numerous scientific schools are open for those students who her devote a still larger share of their time to scientific study. T ; case, however, is very different in the lower schools. Bomani science is usually taught in the high schools, though not, as & ™ us to those who are preparing for college. But in the lower i there is usually little or no teaching of science. The result is t! ‘ those whose educational course ends before they reach the = school (the great majority of the population) receive no ene: : in science whatever, and those who receive a college education ( destined intellectual leaders of their generation) receive 0 ue tion in science until a very late period in their educational cou Science- Teaching in the Schools. 771 This exclusion of science from the early stages of education, and (for the great majority of the population) the consequent utter exclusion of science from their educational course is, I believe, the worst feature of our present system of general education. The introduction of science into the lower schools is the educational reform most urgently demanded. One important reason for this reform is implied in what has been already said. If any knowledge or appreciation of science is to be generally diffused in the community, it must be by the intro- duction of instruction in science in the lower schools. Of the scholars who enter the primary school, only a small part reach the grammar school, and a far smaller part reach the high school. When we consider that the “people are destroyed for lack of know- ledge”—that the preventable mortality due to simple ignorance of hygienic laws exceeds the slaughter of the bloodiest campaigns ;— when we consider that not only is the duration of life lengthened, but its comforts and means of higher development prodigiously increased, by scientific knowledge ;—when we consider that each man’s knowledge or ignorance may not only affect for weal or woe himself and his own family, but may involve results whose ramifi- cations in space and time are beyond our ken :—we cannot fail to recognize the importance of providing for all our population the means of gaining some acquaintance with those branches of know- ledge on which the welfare of humanity so largely depends. Another reason for this reform, though less obvious, is perhaps even more important. A sound system of education must take account of the natural order of development of the mental faculties, Nor need we be in any doubt as to what that order is. The per- ceptive faculties are the earliest to be developed; later come into activity the powers of abstract thought; later still does conscious- ness become reflective, and reveal the world of mind. The atten- tion of a healthy and normally developing child is given almost exclusively to the phenomena of the external world. The ques- tions which he asks his parents and other adult friends (if he has not been snubbed too many times in such questioning) relate almost exclusively to objects of sense around him. There are, indeed, miraculous children who speculate about the nature of the soul almost before they molt the long dresses of babyhood; but such a 772 Science-Teaching in the Schools. children usually die of precocious genius or early piety on the brain, and may therefore be disregarded in any discussion of general education. Young children in process of normal development are what some one has called the Buddhists—“ unconscious material- ists.” They do not disbelieve in aspiritual world; they ignore it. The early development of the perceptive faculties produces in the young child’s mind a natural curiosity in regard to sensible objects, and therefore a natural aptitude for their study. There are three ways in which we may deal with this mental tendency. First, we may leave the child’s curiosity about the external world to unrestrained and unguided indulgence. We may let the child run wild through field and forest, chase butterflies, rob birds’ nests, and fill his pockets with caterpillars. He will grow up a young savage, with somewhat of a savage’s field-craft and wood-craft, but with very little of valuable intellectual development. Secondly, we may repress the child’s natural curiosity. And, in fact, that 1s about what is usually done. The child is taught to read as early as possible, and then the idea is sedulously inculcated that reading is the straight and narrow way that leadeth unto intellectual life. The story of Sir William Jones’s mother answering all her son’s questions with the words, “ Read, and you will know,” is told with express and implied enconiums upon her wisdom and her son’s consequent vast erudition. Verily, the ghost of that good woman haunts our schools like a malignant spirit. The climax of success is reached when the little monk is snugly cloistered with his books, oblivious of the very existence of a world of light and music around him. And if he grows up to be one of the favored few who are permitted to enter the sacred precincts of the college, and there take up the long-deferred study of nature, he finds too often his powers of observation well-nigh atrophied by long disuse. I speak strongly , because I speak from experience. I feel daily that the efficiency of my work as a student and teacher of science is impaired by that vice of early education which repressed, rather than developed, what- ever powers of observation nature had given. My professional life has been a perpetual struggle to rid myself of some of the ment habitudes induced by an unnatural education. I have not yet quite freed myself from the influence of Sir William Jones’s mother. And what I have felt in myself I have seen in my students. It 1s Science-Teaching in the Schools. 773 worse than making bricks without straw, to teach natural science to college juniors and seniors, in whom disuse has wrought so complete an atrophy of the powers of observation that they hardly know that there is an external universe. Manifestly, the only right course in education is to furnish intelli- gent and sympathetic guidance to the child’s natural curiosity. The study of nature should be introduced at the beginning of the educa- tional course, instead of near its end. It should commence—not in the primary school, but in the nursery, before the child is old enough to go to school at all. A vast deal of knowledge may be smuggled into the child’s mind without paying any duty of conscious toil. And such smuggling is forbidden by no laws of God or man. No child is hurt by knowing too much; though many a child is hurt by learning things in unnatural and unduly laborious ways. What- ever of useful knowledge a child gets while he thinks he is playing is clear gain. The sentiment, “ No profit grows where is no pleasure ta’en,’’ may not be strictly true, but there is at least an important truth in it. Some years ago I had the pleasure of a somewhat intimate acquaintance with a boy who, in his third summer, became very much interested in flowers, or, as he called them, “sowers,” for at that time his language, besides being very scanty in vocabulary, presented some marked dialectic peculiarities. Having obtained Some specimens of the tawny day-lily (Hemorocallis fulva), he noticed the long slender bodies in the middle of the flower, and he asked his mother what they were. It seemed almost absurd to be teaching botany to a baby hardly more than two years old, but his mother, having large faith in the general principle that the best way to answer a child’s questions is to tell the truth, told him that the things he had found were the stamens and pistil. Of course the baby did not know much about the objects which he examined. It was not time for his brain to be disturbed with matters of mor- Phology and physiology. It was not time for him to learn that stamens and pistils are peculiarly modified leaves, or that they are respectively the male and female organs of reproduction. But his eyes were often busy that summer in looking for the stamens and Pistils in various flowers, and in that simple matter of observation 774 Figuring against Weeds. he succeeded quite as well as some college juniors I have seen. And when, in after years, the time came for him to take up the study of botany more systematically, the objects of his study were to him not dim and unreal phantoms, but familiar friends. To be continued. FIGURING AGAINST WEEDS. BY BYRON D. HALSTEAD. fas weeds are among the worst enemies of the farmer. They cause a loss of many millions of dollars annually to the State of Iowa. This is not only in the diminution of crops but no small share of the outgo is in labor in order to prevent an entire loss of the crop. Some persons, who as yet have secured no world-wide reputation for keen common sense, are inclined to look with much favor upon weeds. To their visionary minds they are simply a proper stimulus for the profitable tillage of the soil, and therefore may be considered as the friend instead of the enemy of the progressive farmer. If it were not for the weeds, which spring up and choke the neglected crop, there would not be sufficient incentive to good husbandry. Good and poor farming would be more equally rewarded. The man who hoes and the one who leaves his corn field for the shade and game along the wooded stream would stand a common chance of plenty at the harvest time. In short, weeds are the appointed means of putting a premium upon farm industry and furnish one reason why it does not pay to be shiftless. This is turning the curse into a blessing, and if every one woul practically make this turn there would need to be but little more said. Weeds are a good deal like the sun and the rain in pean the just and the unjust, with perhaps this variation, that the w seed abundantly on the neglected land of a shiftless farmer and a same seeds find their best places for growth in the clean rich fi of the careful husbandman. Figuring against Weeds. 775 But all this aside; it is true that the State of Iowa has already more weeds than she wants for the purpose of premiums. Her good farmers get enough encouragement for being good without having their less prosperous neighbors loaded down with a heavy weight of thieving weeds. I for one would be willing to risk the quality of Iowa agriculture if every vile weed within our borders was rooted out and all their seeds burned to smoke and ashes. The conditions which surround our prairie farming, foster the growth of weeds. Land has been very cheap and at the same time very rich. The first fact has encouraged a spirit of carelessness on the part of the farmer and the second has permitted the rapid multiplication of rank weeds. Asa result our State is becoming almost overrun with plant-pests of both the field and the garden. The time has come when an earnest study must be made of the weeds which rob our land, already losing much of its virgin fertility. We must come to the rescue while the enemy is compara- tively weak. Education is more effective than legislation. It is not difficult, perhaps, to pass a law against cockle-bur, beggar’s lice, Canada thistle, ete., as has been done in many States, but an act of the legislature does little good until there is a keen apprecia- tion of the importance of clean fields and road sides, already in the minds of the farmers. With a view to becoming better acquainted with the weeds and useless plants of the State, a list has been prepared which embraces : (1) all the worst weeds, (2) the bad weeds, and (3) the indifferent weeds. The first class includes fifty-one (51). In the second group are ninety-four (94) kinds; and among the indifferent sorts are one hundred and fifty-two (152) species. This gives a total of two hundred and ninety-seven (297) distinct kinds of plants of no great usefulness to the farmers of the State, half of these a positive disadvantage and over half a hundred being pests of the worst sort. When thus arranged the enemy makes a long and bold front. If we look at these enemies in the light of their term of life—as the horseman would say, look in the mouth, it is found that eighty- four (84) are annuals ; twenty-seven (27) are able to live two years at the most, while one hundred and eighty-six (186) are perennial, that is, thrive for an indefinite term of years. ‘These figures can _ thrown into a tabulated form suitable for the blackboard, us :— 776 Figuring against Weeds.

The large balance of two hundred and ten (210) are natives and are weeds in their wild state or have made inroads upon cultivated land. Of the 87 foreigners, forty-four are annuals, that is, running through their whole life in a single season, twelve (12) are biennials, and thirty-one (31) are perennials, Twenty-eight of the eighty-four are in the worst class, thirty-seven in the bad group, and twenty-two belong to the indifferent order.

Itis no comfort to know that more than half of our most aggressive weeds have come, or been brought, to us from some other country. If there is any satisfaction 10 the thought, it may be here stated that some inoffensive sna plants have gone abroad and became dreadful pests in their new surrounding. In this way we compensate in part for the additions made to our list of weeds from European and other lands. Figuring against Weeds. 777 Beginning with the foreign annuals the leading worst kinds given in the order of arrangement in Gray’s Botany, are: charlock or yellow mustard, shepherd’s purse, corn cockle, purslane, abutelon or velvet leaf, sun-flower, mayweed, Jamestown or jimson-weed, two species, goose-foot or lamb’s quarters; pig-weed, tumble-weed, chess and three kinds of fox-tail grass or “ puss-tail.” The three foreign biennials are the common carrot, parsnip and the hound’s-tongue. Two of these are closely related and have escaped from the vegetable garden where they are very important root crops. The carrot and parsnip are not as bad weeds in Iowa as they have become in many parts of the East where they cover the pastures and meadows with useless herbage. Of foreign perennials the leading worst sorts are Canada thistle, dandelion, rib-grass or narrow-leayed plantain, butter and eggs, toad-flax or ramstead weed, curled-dock and sorrel. Coming now to the native weeds of this most injurious class we find among the annuals the following: Daisy fleabane, great rag- weed, Roman rag-weed, cockle-bur or clot-bur, beggar’s ticks, horse nettle, beaked horse nettle, prostrate pig-weed, knot-grass and bur- grass. It will be seen at a glance that this is a formidable array of bad enemies. The biennials are the evening primrose, a kind of fleabane or horse-weed, and the viper’s bugloss or sometimes called blue devils. This makes a strong three-horse team. Of the native perennia's may be mentioned the callirrhoeä, two kinds of iron-weed, three sorts of thistles, namely : the ball thistle, common thistle and pasture thistle, the bracted bind-weed and quack or quick-grass. By turning the figures of the tables to further service, it may be shown that there are nearly twice as many foreign weeds of the worst sort as of the natives. Twenty-eight out of the fifty-one live for only a single year. Six only are biennials and seventeen are perennials, This we should not expect because other things remaining the same a perennial is a worse weed than an annual. But other things do not remain the same. The annual is usually characterized by great capacity for forming seed, and this advances many of the annuals to the first rank among plant pests. For example, the common purslane will mature a million seeds in a _ 178 Figuring against Weeds. single season or enough to thoroughly stock a country with this pest. A student made a careful estimate of the seeding capacity of a single plant of the small veronica, called niclace speedwell, and found that the number of seeds was 186,292. These figures help to force home the thought that weeds, and especially these sorts which are dependent upon seeds for their continuation, are exceed- ingly prolific, and also the importance of keeping such pests from maturing their offspring. When asked to select the most offensive among the worst weeds the task becomes an exceedingly difficult one. Among the annuals, especially in gardens, the purslane or “ pusley ” perhaps takes the lead. In striking contrast with the prostrate purslane is the shrub- like Jamestown weed or stramoniums, sometimes called jimson weed. The rank herbage and heavy order of these coarse weeds, as well as their larger size, make them conspicuous and disagreeable. The pig-weeds and the closely related tumble-weed are common coarse intruders into the tilled ground. Of the biennial the most to be dreaded are the carrot and the fleabane, both of which, in their own widely different way, can do much to render the life of the farmer vexatious. The worst foreign perennial, at least the one with the most meanness in its make up, is the Canadathistle. At present it is but little known in many parts of the State ; but it spreads rapidly by means of its airy floats which bear the light seed for long distances, and when once established in the soil it holds its place with an almost undying grip. The long perennial roots strike Iowa deep into the soil while the prickly herbage defies the attacks of foraging animals. The curled-leaf dock also takes a firm hold and is eradi- cated only by being dug up by the roots and hung in the sun Or burned. Of the native perennials there are various sorts of coarse thistles and the celebrated quack or quick-grass. This last 15 4 remarkable instance of propagation by undergrown stems. p lowing and harrowing only aids in the spread of this pest. Each piece of wiry stem when given any sort of a chance will grow and develop the weed. As a rule the weeds of all classes should never be permitted to mature their seed. With annuals this is a quick and effective means of eradication. The biennials will perish at the end of the The Central Philippines. 779 second year. Perennials may live on for several years but if they are not allowed to develop much herbage and no flowers the old plants will gradually die of starvation and, being without heirs, they will leave the land to revert to its rightful owners. Proper tillage will keep the weeds within safe bounds in the open fields of hoed crops. By proper tillage is understood that culture which the crop demands even when no weeds encumber the soil. The hot-bed for weeds is the neglected corners where the cultivator and hoe do not naturally go. It is in such places, along road-sides, barn-yards, open wood lots and fence corners that weeds sneak in _ and bear their young. It will be difficult to keep the cultivated field clean when all around is breeding ground for foul seeds. Rome was not built in a day and neither will our weeds be destroyed in a generation. It is only hoped that, as all roads lead to Rome, so may all the inward desires and open acts of every producer of crops tend toward the destruction of our worst weeds. THE CENTRAL PHILIPPINES. BY J. B. STEERE. (Concluded from page 626.) AFTER much enquiry for a suitable place to collect in, we heard of virgin forest in the north part of the island of Panay, and finding a little steamer running up the coast we took passage to the village of Concepcion, some twenty miles north of Ilo Ilo, and nearly in front of the curious conical island called Pau de Assucar. Woods were in sight, but we found that they were steep and rocky, and difficult to hunt in, and rather unproductive of forms new to our collections, most of the birds being identical with those already procured in Guimaras. The forest had a curious half-dead appear- ance, which was due in part to most of the leaves having already, in January, fallen, preparatory to the coming spring, and in part to much of the timber having been injured by large gashes in the trunks to collect the gums from them. Before we left the place | Some of the trees were already showing the purple and bright yel- 780 The Central Philippines. low tints of the new foliage. Spring does not come all at once, nor to all plants at the same time, here; but I think that even here in the tropics every plant has its annual period of rest from growth, of leaf-shedding, and of spring, though there is no long period of time, as with us, between the last two processes, the new growth here usually crowding off the old leaves, though a few species, like some of the wild figs, are bare for some time before the appear- ance of the new leaves. These have in some instances led us to believe them dead from their bare appearance among the univer- sal green. The country along the coast at Concepcion was hilly and unpro- ductive, and uncultivated, and it was a mystery how the people existed, until we followed the roads leading back into several large level valleys which had been brought under cultivation, the lower parts, which could be flooded, to rice, and the higher to sugar cane. A few Spaniards and Mestizos had settled here, and were hauling their new sugar in buffalo carts to the coast for shipment. We passed several great sheds which served as sugar-mills, the machinery being in some cases upright wooden rollers turned by buffaloes, in others, small steam engines imported from England. On the wet rice grounds, now grown up to and grass, we shot a few rare water fowl, among them the great blue and purple heron of the Philippines. At a village on one side of one of these valleys we found a roost of fruit bats. Three or four acres at one side of the roadway, grown up to scattered ‘clumps of bamboo, and in the bending tops of these the bats were clustered. The immense masses of small prickly branches, at the bases of these clumps, curve downward, and make thickets hard for man or beast to pass over or through to the trunks beyond, and they appear to be chosen by the bats for this reason. - We passed at least four distinct species of fruit bats inhabiting this grove, though each species was found by itself in particular trees. As we approached them, about noon, they hung, in pin quiet, head downwards, by both hind feet, the wings being fol a about the body so that they looked like clusters and strings great pendant birds’ nests. They were accustomed to the peop’? of the village passing beneath them, and paid no attention to US ‘until we began to shoot among them, when they rose squealing The Central Philippines. 781 into the air. After wheeling around like spectres over our heads for awhile, they would approach a perch, and throwing the hind feet forward, would grasp it, and fall down into their accustomed position. After they became alarmed they would take flight at our approach, and they appear to see fairly well by day. A few shots were sufficient to fill two large baskets, and made a good load for a native who carried them back to town. The next day, while skinning them, we had frequent visits from the villagers, who carried off the bodies to eat. They have a strong, disagree- able, bat odor, but are said to be good eating. The larger spe- _ cies were from fifty-four to sixty inches in spread of wing, the smaller ones about forty. They fly to great distances in their search after food, leaving their roosts at dusk and returning just at daylight in the morning. They become a great pest to the natives, though they may be benefactors in disguise, by nightly visiting the bamboo cups in the coco trees in which the sweet juice of the flower stems is being collected for tuba, the beer of the country, as the people are fond of calling it. Sometimes the bats take this when it is too much fermented, and the next morning finds them rolling about on the ground under the coco trees instead of on their way to their roosts, and there they are at the mercy of any crow that wishes to tear holes in their wings with his beak, or of the swine that make a meal of them. We were brought several which were caught drunk. From an examination of the stomachs of those collected, this coco juice seems to be their chief food, and must in time have its influence over their anatomy. Having completed our work in Panay and Guimaras, we em- barked again on the 1st of February, and 1«unning down around the south end of the great island of Negros, landed at Dumaquete, a clean little town just opposite the southern point of Cebu, and so near that island that we could see the trees across the strait. The south end of Negros had appeared, as we passed around it, a great stretch of grassy plains and hills, now dry and yellow, and being burned over in some places. The mountains approached nearer at Dumaquete, and we could see forests on their heights. They were volcanic, and what we judged to be ancient lava streams extended down from a height of two or three thousand feet to near sea level and with such an even grade that they looked like gigantic rail embankments. 782 The Central Philippines. We found at low tide a great number of beach-inhabiting bird- on the flats north of Dumaquete. There were many species of curs lews, plovers, stilts, sandpipers, oyster catchers, ete., all in flocks and most of them probably migrants. After we had procured all of these we wished the party divided. Three of us took a native boat and sailed across to the little island of Liquijor, where they - made a good collection of birds, two or three species of which appear to be peculiar to the island. They also found sea shells abundant, and among other rarities procured a living pearly nauti- lus. The rest of the party went north along the coast of Negros and the strait of Tañon, and stopped at the village of Sibulau, near , the foot of the mountains. Birds were abundant in the wooded ravines, but though we procured many species we had not seen in Pauay and Guimaras, they were apparently such as depended upon a more favorable location, and not upon a real change of habitat, for the hornbills, woodpeckers, tailor-birds, pittas and sun-birds, which we had learned to look upon as test species, were identical with those from the islands named. Hearing of some unexplored mountain lakes to the west of us, we made a trip inland in search of them. At a height of fifteen hundred feet we reached virgin forest, among which were fine oe ferns in abundance. The whole country was steep, but the natives were plowing in and cutting off the timber from the steep moun- tain sides, and planting them to abaca, the so-called Manila hemp. This is a species of banana, and looks so much like those planted for their fruit that we had difficulty at first in distinguishing them, but the abaca thrives best in a cool and moist situation. We found it afterward growing luxuriantly at a height of three thousand feet, while those varieties used for food thrive best near sea level and in the greatest heat. Like the other bananas, the abaca forms a trank from eight to twenty feet high, made up chiefly of the bases of the leaves, these wrapped one over the other, and it is these which es made use of. They are torn apart, and the outer covering of ae outer or convex side is stripped off. This contains the fibre, th the rest of the leaf base being made of large watery cells. It 2% drawn through a wide machine made on the spot by the awe cultivator.

The hemp comes out white and glistening, and requires no other preparation but drying to fit it for baling and shipment. Through the fall in price of sugar, hemp is now the most impor- tant article of export from the islands. We reached a height of three thousand five hundred feet, the path leading for most of the way along the narrow crests of moun- tain ridges. Oaks were plenty at these heights, and with them Indian pitcher plants, a beautiful colored leafed begonia, a colens in in flower, and a great number of ferns, and mosses. Everything was dripping with moisture, and land leeches were crawling over the ground or hanging from ‘the plants ready to drop upon us. The lakes were small—one a half mile, and the other perhaps a mile in length, and at a height of about three thousand feet. They were in steep ravines between mountains, so that there were no val- leys about them in which we could hunt. A step from shore on any side took us over our heads in water. Deer and wild hogs were abundant, and our Indian hunters tried to drive them into the lakes with their dogs, but without success. The only life we saw in the water of the lakes was leeches, of great size, and crabs and water-fowl were almost absent. A few great hornbills were flying from one mountain crest to another, but it was folly to attempt to follow them. ; We found a little piece of level ground at the mouth of a moun- tain brook, where we built us a shelter and camped. We shot a few species of flycatchers from the trees over our hut, and after staying two days, and sleeping cold with the themometer 67°, we descended to the coast. While some of the party went on to Cebu by steamer, a division crossed the strait of Tafiau to Cebu, and fol- lowed the west coast of that island to the town of Barili, then crossing the mountains to the east coast followed this to the north until we reached the city of Cebu. This is the oldest Spanish town in the islands, and is the capital of the island and a port open to foreign trade. We found the island of Cebu still more thoroughly stripped of its timber than the islands to the west, but after doing what we could to get a fair collection of its birds we concluded that it, too, belonged zoologically with Negros and Panay. A brief visit by two of us to Bojol convinced us that this, too, must go with the islands to the 784 Derivation of the Domestic Polled Breeds. west of it in a division which may well be called the Central Phil- ippines. Bojol and Cebu have large amounts of limestone rock thrown up in steep ridges, and this has probably caused their great richness in land shells, of which each valley seems to possess a spe- cies. The shallow strait between these islands is rich in sea life, and a week spent in the little island of Waiming produced a fine collection of corals, echinoderms and sea shells. Crinoids were abundant in the shallow water, and of several species; they were usually partly protected among the branches of living corals, but sometimes fastened, mouth upward, to stones and coral masses. An immense spiny star-fish was slowly crawling over the coral stems, digesting the polyps as he went, and leaving a broad white track of dead coral behind him. Returning to Cebu, we packed our col- lections, and left them to be forwarded by sailing ship to New York, and took passage on the last of March for Saman and Leite, the most eastern islands of the group. THE DERIVATION OF THE DOMESTIC POLLED ~ BREEDS. BY R. C. AULD, F. Z. 8. (Continued from page 509.) n lere part had these polled cattle of the parks in the origm of the existing domestic breeds of Britain, now so numerous!y represented in this country? Instances have been enumerated x the existence in widely scattered places of polled cattle of vario descriptions. Out of all these did any survive and become pn gated more into certain localities, and thence evolved into pages and distinct breeds? The connection of the park cattle with “af breeds of polled cattle in their former and present state will here be traced. eae Sir Richard Owen, in advocating his theory as to ha s British cattle, which is at variance with that of Da ae Nilson, Riitimeyer, etc., says: “ Had the Bos primgenws yee 5 same we might have expected the Highland and Welsh ca tors have retained some of the characteristics of their great prose” Derivation of the Domestic Polled Breeds. 785 and to have been distinguished from other domestic breeds by their superior size and the length of their horns. The Kyloes and the runts are, on the contrary, remarkable for their small size, and are characterised either by short horns, as in the Bos longifrons, or the entire absence of these weapons.” With all due respect to Sir Richard, exception must be taken to his ideas as to the characterisation of the Welsh and Highland cattle. Has he ever seen either race at the Smithfield Show at London, or other National Shows, or on their native heath? If he had he would not have fallen into the error of characterising these cattle as of small size, or short horned, or wanting in the charac- teristics of their progenitors, the Uri. If he had seen them as they may be seen, he must have been convinced that they do possess the strongest claims to such descent of any existing race, in respect of size, length of horn, and general characteristics. This is the common error that many have fallen into, not having seen repre- sentative or real specimens of the breed. How many animal forms have not large and small associated varieties or species? This needs no illustration. Besides, “size” depends not always on Species, but on environment. That these small and large Scotch horned correspond respectively with longifrons and urus, we believe, however, is true. _ Contrast with Owen’s ideas the practical knowledge of Professor Low. In his “Domesticated Animals” he says: “ These English White Forest breeds have merged in the common breeds of the country.” He believes, however, that the same animals are yet to be found in that part of the Kingdom where we should naturally look for the existence of an indigenous race of. cattle, viz., beyond the Severn, in Wales, and in the West Highlands. “The mountain breeds of Scotland,” he says, “ are identical with those which formerly inhabited the woods of that country, which, we have seen, were the ancient Uri, and which we may term the White Forest breed.” He has also some excellent remarks on the Comparative size of the Urus and his modern representative, which are too long to quote. But he says: “The size of the Pembroke cattle is that of the larger class of the breed of the West Highlands of Scotland ”—which corresponds with all practical breeders’ know- ledge on the subject. 786 Derivation of the Domestic Polled Breeds. We may leave Low here with the following quotations: “Thus we have all the evidence which the question admits of, that no real distinction exists between the wild oxen of the parks and those which have for ages been subjected to domestication in the same country, and that these wild oxen are no other than the Uri of the ancient forests of Europe.” “Thus were the Uri of the Scottish forests driven from the woods which they inhabited, destroyed, or made captive. Part, indeed, had been preserved in some of the religious houses, their flesh being more esteemed than that of ‘their ain tame bestial? But with the destruction of the ancient establishments, the oxen were dispersed, destroyed, or mingled with the common races. In a few places only they seem to have been preserved without intermixture—chiefly in the parks of the Dukes of Queensberry at Drumlanrig, and of the Dukes of Hamilton, at the Chace of Cadzow. Those at Drumlan- rig were, many years ago, destroyed by order of the late Duke of Queensberry. Those at the noble park of Hamilton are yet in existence, preserved with care.” He describes them as “ indubitably descendents of the ancient race,” and as to their size says they are in that respect the same as the cattle of the West Highlands. For convenience I continue from last chapter the consideration of the Scottish parks. And it is necessary in this investigation to examine these somewhat closely, so as to obtain a proper definition. of their limits, and to exhibit the direct connection they had with the polled breeds of to-day. Sir W. Jardine, Bt., (Naturalist? Library, Vol. IV.), makes these remarks in describing the “ White Urus, or Hamilton Breed of Wild Cattle”: “The Caledonia Sylva, or Caledonia Forest, . extended from Stirling through Monteith and Strathorne to Athol and Lochaber. It is described by old authors as dividing the Picts from the Scots, and, being well furnished with game, especially with the fierce white bulls and kine, it was the place of both ther huntings and of their greatest controversies. The Roman historians delight much to talk of the furious white bulls which the Forest of Caledonia brought forth... .. At what period the present breed was introduced to the royal chase at Cadzow cannot now be well ascertained. It is well known that the Cummings [Earls of Buchan] were at one period proprietors of Cadzow and Cumber- Derivation of the Domestic Polled Breeds. 787 nauld, and it is likely that in their time the white cattle were in both places. But, be that as it may, they have long been extir- pated in Cumbernauld, while they have been preserved in great perfection at Hamilton.” This description of ancient “ Caledon,” given by Jardine cor- rectly from the earliest historians, should be remembered. For, more latterly, authorities, even such as Sir Walter Scott, described the Caledonian Forest as extending over a territory of which “Cadzow and Chillingham are but the extremities,’ “which in ruder times was a continuous forest, the white cattle being the remnants of those herds of Tauri sylvestres, described by early Scot- tish writers as abounding in the forests of Caledonia.” This latter region, as a look at any map showing the boundaries of the different regions in these early times! will show, was the ancient Strathclyde—the western portion of southern Scotland and northern England, the adjacent portions on the eastern side of England and Scotland being Northumbria, while “Caledonia,” So says the writer in the Encyclopedia Britannica, “lies to the north of the Forth,” but must include the region of the Clyde which flows north. This Caledonia in the west—called Dalriada ——came to be inhabited by the Irish Scot or Gael, while the east remained Pictish. These Dalriadans were the great Scots about whom historians have had so much to do. The Galloway, “ Wild Scots,” were afterwards conquered by the true Scots of Dalriada, the name Galloway not indicating the composition, but the con- queror, of the Pictish inhabitants. The Pict, that is, of the east or northeast, “came from Scythia—that is, North Germany—as their own legends tell, which was undoubtedly peopled by Celts before it was peopled by Germans.” Let us, then, look at the park herds in Scotland—the Hamilton, the Ardrossan, the Drumlanrig. The first is located in the great Caledonian region defined by Jardine, Storer, Harting and others, as above. The two last belonged to ancient Galloway: The Ardrossan and Drumlanrig (Duke of Buccleugh) were horned ; the Hamilton was polled. The significance of these facts will appear when the history, literature and philology of the two regions are examined, 1 See Skene’s “ Celtic Scotland.” 788 Derivation of the Domestic Polled Breeds. The parks became enclosed in ancient times, and with the enclosing the wild cattle became enclosed also. These cattle were the Uri of the north, whose originating source was the ancient. cattle of Cumbernauld, near Stirling. These then becam® extinct, having been scattered, part being preserved in the polled cattle of Hamilton. “The wild bull of the north had, therefore, anciently free access to the whole of southern Scotland, and to the mountains, wastes and forests of northern England also.”! The Cumbernauld extinct herd “thus connects north and south; the wild bull of the old Caledonian Forest north of Stirling with the Hamilton wild cattle, and with those which inhabited, as described by Scott, the continuous mountain ranges and the innumerable forests which formerly extended from Hamilton to Chillingham.” Hamilton was thus near the fountain-head. Their representatives at Cadzow, and over the north, were polled. This territory was the pasture region of the polled cattle of Fife, Angus, Aberdeen, etc. At Drumlanrig, in the pasture ground of the Galloway, they were horned—in that indicating the character of the original Galloway breed. Take now the Hamilton cattle possessing as its hunting ground all northward. These were the famous white bulls of Caledon, descended, as all authorities agree, from Bos wrus ; and which were also by all historical accounts polled. This herd belonged, before the days of the Bruce, to the Cummings—the great but unfortunate Earls of Buchan. But further, Hamilton Palace was the seat of the Douglas- Hamiltons, Dukes of Hamilton and Brandon, who represented through the male line the great Douglases, Earls of Angus. Here, therefore, we have the Hamilton (Cadzow) herd connected in the closest manner with the shires of Aberdeen (Buchan) and Angus: Hence are traced the roots of the Aberdeen-Angus breed of polled cattle, firmly spread over the more lowland portions of the Caledo- nian region. And it is a further historical fact that it was from royal Kildrummy, in Aberdeenshire, after his spoliation of the Cummings, that King Robert the Bruce, in the thirteenth century, 1 See “ Wild White Cattle of Great Britain ;” also “ Domesticated Ani- mals of Britain.” Derivation of the Domestic Polled Breeds. 789 issued to hunt the wild bulls of the Caledonian forest, which region extended thus from royal Kildrummy to royal Stirling. The origin of the name Caledonian is derived from the word Calder, signifying the hazel brush. In the Transactions of the Highland Society, Vol. XVII., 1885, it is stated that in Lanark- shire, in which the Hamilton herd is situated, “fifty years ago some had cows of the native or Calder breed; others crosses with these and Ayrshires.” The word Kyloe, also, is derived from the name of this forest region, the word meaning cows of the woods— both words having one root in common. The Drumlanrig and Ardrossan herds are extinct. These herds were horned [the latter having latterly become polled on the intro- duction of polled bulls from Hamilton.] And just as the Aber- deen-Angus had their roots in the Caledonian polled varieties represented by the Hamiltons, so had the Galloway its foundation from the same horned cattle that became enclosed at Drumlanrig. Drumlanrig Castle, in Dumfriesshire, is located in the valley of the Nith, between Hamilton and the Firth of Solway, but nearer the latter. The owners of this castle were that branch of the house of Douglas which enjoyed successively the titles of Earls, Marquises and Dukes of Queensberry. The Duke of Buccleugh, as heir general, is Duke of Queensberry, and possesses Drumlanrig. While, as will be seen, Hamilton was transferred to the Angus- Douglases on the extinction of the Comyns by Bruce, Cumber- nauld, likewise owned by the Comyns, became transferred by Bruce to Sir Robert Fleming, who was the ancestor of the Earls of Wig- ton, and it was probably during the time of Queen Mary, when the Flemings were out of favor at court, that the remnants of the Cumbernauld herd got dispersed, and some might have been trans- ferred to Dumfriesshire, Anyhow the Drumlanrig herd also went by the name of the Wild Caledonian Cattle. They were white with black points. Mr. Dickinson, in his Essay “On the Farming of Cumberland,” pub- lished 1852, identifies the Drumlanrig cattle also with the Caledo- mian Forest Wild Cattle. The herd has been long extinct. Drum- MNE was located at the foot of these wild hills, which extending throughout southern Scotland, were the ancient haunts of the Scottish bull. « Castle Dangerous,” which Scott describes as among 790 Derivation of the Domestic Polled Breeds. the mountains which gave shelter to the wild bull, is not far off. These“horned cattle, mixed with the local Bos longifrons, probably gave origin to the modern breed of cattle of that region. It was in the late Duke of Buccleugh’s knowledge that his favor- ite race of Galloways—of which he was the champion—was, up to the middle of last century, a horned race; and he, true conserva- tive, deplored the change. Perhaps the change had been wrought in a similar manner to that of the Ardrossan herd; or by some influence of the territorial magnates on their acquirement by political means of a connection with a country containing among its wild cattle many of the polled variety. The climate of Galloway region is described by writers on the breed, explaining thus the coarse hair that is a characteristic of the Galloway, as very humid. And we see also the result of this humidity in the coarse horns of the historical breed. Darwin quotes Prof. Low as to humidity of climate producing hair in abundance ; and Youatt has also stated the correlation between coarse hair and horn. “We can thus see how a humid climate,” says Darwin, “ might act on the horns—in the first place directly on the skin and hair, and secondly by correlation on the horns.” While the Galloway men themselves explain the finer coat of the Aberdeen from “ the drier” climate. : And there is an absolute dearth of any collateral evidence, deriv- able from local literature, philology, sculpture, etc., to indicate the non-existence of horns in this ancient breed; the tradition, as will be shown, being that they were anciently universally horned. ABERDEEN-ANGUS BREED. As the lowlands of the Caledonian region belong entirely to the counties associated with this breed, and as the breed from the earli- est times was the same foundation, the maol Kyloe, the Hartt polled, the dodded of the Meigle sculptured stones, the homyls ° King Kenneth’s time, and the hornless neat of T. Kirke, etc., must be accepted as the progenitors of this world-famous race of cattle Formerly everything connected with the history of the breed was wrapped in obscurity—they being an unknown breed (to the out- side world) in a terra incognita. I have in this investigation brought forward here what is new or of such importance aS the subject required. Derivation of the Domestic Polled Breeds. 791 Investigators, in their researches into the history of this breed, have been chagrined to find in the first or second of the Surveys of the County of Aberdeen, drawn up for the Board of Agriculture, that no mention is made of any of the native breeds as being horn- less, This, now, is regarded as remarkable, and more so for the reason that the author of the first Survey was a man of consider- able repute, Dr. James Anderson. The first series of these surveys. _ Were, however, written chiefly from the strict agricultural point of View. The live-stock was undesignedly overlooked. So much, Rowever, did this prove to ‘be tho case: that a second: arriet was 792 Derivation of the Domestic Polled Breeds. organized for the purpose of rectifying the mistake. There were about ten years between the two series. The first Survey of the Agriculture of Aberdeenshire, by Dr. James Anderson, of Monkshill, in the Buchan district, was pub- lished in 1794. The author never mentions horn or hornless in describing the two breeds that come in for notice. One of these can, however, be identified with the old long-horned Aberdeenshire breed, described as being fine and rich milkers; the other, men- tioned as the cattle of Buchan, which can be identified by the evi- dence of his own household as the native low-country polled Buchan. He gives good general testimony to the high character of the latter. James Anderson, LL.D., was born near Edinburgh, 1730; died in London, 1808. He farmed extensively in the Buchan district of Aberdeenshire. He was a voluminous writer, and is thus referred to by Darwin (“ Variations of Animals and Plants,” second edition, Vol. I.): “Another ingenious writer, though not a natur- alist, with a bold defiance of everything known on geographical distribution, infers that the sheep of Great Britain alone were the descendants of eleven endemic British forms!” Yet he was quoted largely by others. Having resided so long in Buchan, it seemed incredible that such a man® such a ready observer, even though not a naturalist, should have escaped noticing, in some way, the special peculiarity —as hornlessness was apparently to him—of the cattle of that region, named, indeed, from that peculiarity itself, Buchan Hum- lies, from time immemorial. So it appeared to the general student. But, for the reasons mentioned, it appeared to me that he must have made some such allusion. So I carefully examined all his works likely to contain anything of the nature sought. In his “ Recrea- tions in Agriculture and Natural History, etc.” completed in S1% volumes, I find him descanting thus (p. 67, Vol. I., published 1799, “ On Varieties of Animals: an enquiry into the nature of that department of Natural History which is called Varieties among Animals, etc., with some cursory hints upon the same term as applied to Vegetables”): “If a chance individual be produced that is of a large size, or particular make of body, the descendants í that individual, if mated with one having similar peculiarities, will be of the same kind, The same thing will happen if it have 4 Derivation of the Domestic Polled Breeds. 793 tendency to fatten more kindly, to yield a greater or smaller quan- tity of milk, to lay fat on a particular part of the body, to produce more or less tallow, to be more or less hardy, or any other peculi- arity. Even accidental blemishes may thus be perpetuated. If a hornless individual be born of a hornless breed of creatures,! this may give rise to a whole tribe of hornless beasts of that kind, which will propagate their like with as little deviation as takes place in the original stock. If a kind of creature that usually carries two horns chance to produce one with three, four, or six horns, you may thus obtain a breed having many horns. Thus we are able to account for those families or breeds of domestic animals which differ in regard to certain particulars of the kind above spe- cified, and which, when once introduced [or appearing] into a cer- tain district, have a tendency to continue themselves in that district for a great length of time if considerable pains be not taken to alter it. The means of altering such a breed are, however, from the facts here stated, clear and obvious; nor can it be effected with certainty but by a change of blood, or an intermixture of breeds. If the qualities of the peculiar breed are excellent, the means of improv- ing it are equally obvious, the selecting of the best individual of that breed, and which have the wished-for qualities in a higher degree than the ordinary, to breed from; and, if they be done with ease and judgment, its effect will be certain and by no means liable to any kind of doubt.” The reference in the Index to the above passage is: “ Hornless breeds of cattle, how produced.” The above affords a good deal. In the first place Dr. Anderson regarded cattle without horns a blemish. This would prove that he was unacquainted with any other polled breeds, if such there were, in Scotland. If he had, he would not have been able to regard it as a blemish. Secondly, that these polled creatures had continued in that district for a great length of time, and had occurred indige- nously previously to his advent in the country at any rate, which would take us back to the beginning of the century (1700). ‘I would direct attention to the use of this word creatures, which Sounds so peculiar to an old country man, and to the new comer to this country, for I found it used pronounced “ critturs’’ to describe cattle. Thus in America the original usage of the word is maintained, like so many others. Indeed, as I show, from the Index reference, Dr. Ander- Son uses the word, also, to describe cattle. 794 Derivation of the Domestic Polled Breeds. Thirdly, he was one of a number (it will be seen, from the means he recommended, at that early date, to eradicate a blemish) who were doing their best to obliterate the old native polled race of such a good quality. He was isolated in Buchan, with only the Buchan Polled breed before his eyes, surprised at the want of the horns he found there to be indigenous, and thus attempted to ex- plain an “ isolated” instance, as he thought it; whereas, if he had had a wider acquaintance with the innumerable polled races that had existed in all time, he would have attempted some more scien- tific explanation—one which I may say here, remembering Dar- win’s allusion to him, has escaped or baffled that prince of natural- ists himself. But the “hornless breed of Buchan creatures” survived the attempt made to obliterate the blemish which had existed for such a length of time, up till 1799, and which had now been setting the fashion for all breeds. Dr. Anderson’s overseer, who began to deal in 1801, has recorded the existence of polled cattle in Buchan during Dr. Anderson’s time, and since then they have become the ‘most famous of polled races. i Now I have brought Dr. Anderson into line, and made him yield testimony to the early existence of the polled cattle of Aber- deenshire, which is about the most important piece of evidence that has been produced on this subject, and is most interesting. THE GALLOWAY BREED. Up to about the beginning of the last quarter of last century the Galloway cattle were horned, and during the middle of that century were “universally” so. The earliest certain account of them as polled is given by Marshall, who wrote in 1782. He says that the best were at that date mostly polled. Andrew Wight, in 1746, mentions them more promiscuously. : The late Sir B. T. Brandreth Gibbs, Hon. Secretary of the Smith- field Club, etc., etc., as General Superintendent of the British Agr- cultural Section of the Paris Universal Exhibition of 1878, in the “Short Introductory Notes on Some of the Principal B of Cattle, Sheep and Pigs,” written by him and prefixed to the Cata- logue of the British Section, says: “Occasionally some have “slugs’ or stumps, which are not affixed to the skull.” Dr. Flem- Derivation of the Domestic Polled Breeds, 795 ing, 1812, wrote similarly about the existence of these “slugs” then, and is quoted by Boyd-Dawkins as evidence of the last appearances in this ancient breed of a reminiscence of its former character. But Youatt twenty years later notices them, and in 1878 Sir B. T. Gibbs also. The above facts are of scientific interest, showing the trans- formation of an ancient race from the horned to polled state. Pro- fessor Boyd-Dawkins has likewise favored me with the following notes :— “The only historical account of the origin of the British polied cattle with which I am acquainted is in the letter of the late Lord Selkirk to which you allude. Lord Selkirk was a man of remark- able ability, and one of the best of the Scotch lairds, and is not likely to have made any important slip. I have no doubt that his account of the breeding out of the horns is substantially accurate, so far as relates to the Galloway cattle. Moreover, on referring to Youatt, p. 155, I find incidental evidence that Lord Selkirk is right.” “Oral testimony,” says Mr. David McCrae, author of a history of Galloway cattle, “handed down to these men from the Galloway breeders of last century, is valuable and reliable.” So the letter from the late Earl of Selkirk, F.R.S., written to Prof. Boyd-Dawkins is of particular value. Boyd-Dawkins in introducing it says: “The polled or hornless cattle of the present day have undoubtedly been derived, through careful breeding, of the horned cattle. The Gal- loway breed has lost its horns principally through the care of the grandfather of the present Earl of Selkirk, to whom I am indebted for the account given in full below. Some fifty or sixty years were consumed in bringing this animal to its present shape ana form.” The letter is as follows; it is dated March 6, 1867 :— “T have no distinct written record about the way the horns of the Galloway cattle were ‘bred out,’ as we cattle-breeders say. The breed 150 years ago was not generally polled, i.e., without horns, though there was always a good many polled ones amongst them. Polled: ones are found in every breed. My informant was an old man who died about thirty years ago, he being then nearly ninety. He was the son of the man who tended the cows of my grandfather, and had been employed among cattle all his life; in his old age, while still able to work, he tended my cows. His 796 Derivation of the Domestic Polled Breeds. name was James McKinnan, and he was a man whose recollections seemed always remarkably clear. He had been with cattle as far as Norfolk, to St. Faith’s fair; he told me that in the days of his childhood, a Norfolk feeder, who bought many of the Galloway cattle, fancied those without horns, and would give 2s. 6d. or so more for a polled than a horned beast. This set the fashion, and the people began first to look for polled bulls, and none other; then they preferred polled cows, etc., to breed from, and thus the change was effected in, I believe from fifty to sixty years. The horns of the Galloway beast were very ugly, drooping, and as thick at the point as at the root. I have myself seen one or two beasts with horns like that; but nowadays, when horns appear they are generally traced to some with a cross with the Irish breed. Those that are born polled have a lump in the centre of the forehead, which is very hard, and will break another bull’s skull for him.” Fria, 2.—“ Galloway Heifer exhibited at Lord Somerville’s cattle show, 1806.”— From the Complete Grazier, 1816, The late R. Gibson, Assistant Curator of the Museum of Science and Art, Edinburgh, Scotland, in the article “Cattle,” in the lm edition of “Encyclopedia Britannica,” arranges British cattle into — three classes: “(1) Polled cattle, an artificial variety, which may be produced by selection; thus, the polled cattle of Galloway small horns so late as the middle of last century, but by only breeding from bulls with shortest horns, the grandfather of the present Earl of Selkirk succeeded in entirely removing these appe?” dages.” Gibson was arguing from the history of only one instance. Aiton, in his Survey of Ayrshire, 1813, says: “ According t0 tradition, the Galloway cows were, in ancient times, uniformly pro- vided with horns.” ; Derivation of the Domestie Polled Breeds. 797 There were numerous introductions of foreign blood into Gallo- way; to give an instance: “Admiral Keith Stewart lately intro- duced [into Galloway] a beautiful Argyllshire bull, which he con- sidered to have made the greatest improvement of any on the coun- try breed” (Agr. Rep. of Galloway, p. 22). That does not look as if the breed was polled. And Aiton says, “Stories were told of bulls being brought from England—north and west—which ban- ished their [the Galloways’] horns for them.” Some also think that it was on the introduction of the Irish moyl that the polled char- acter dates. As Gilbert shows, there was a continuous interchange of cattle between the border counties of England and Scotland. And,as shown by Storer, Low, and the early historians, and our- selves, the tendency of cattle was continually from the north of Scotland to the south, and not vice versa. So that it is difficult to trace a straight line descent for the Galloway, as can be done for the Aberdeen-Angus, whose country was never so invaded. The latter were the real ranche cattle of early Britain, and were the first to open up the highways from the north to the south. THE NORFOLK AND SUFFOLK Rep POLLED BREED. This East Anglian breed of polled cattle is an amalgamation between the “old Norfolk” horned race and the “old Suffolk” polled. The latter could hardly escape having “acquired its horn- less character from contact with the white variety maintained at some of the old establishments in the district,” i.e., the herds of polled cattle in the parks already described. It was not till 1846 that there had been such an amalgamation between the old Suffolk with the old Norfolk as to entitle the two varieties to be recognized a8 one breed. There is in the lobby at Raynham Hall a picture of Starling, a cow of the old Norfolk breed, in the thirty-sixth year ive age, which preserves to us the apparent character of this old Mr. R. E. Lofft gives the following account of the evolution of this race :— “The origin of the present breed of Red Polls is perfectly well known, About a hundred years ago the native cow of Norfolk, a variety peculiar to the county, of a red color, with a white face, and horned, was crossed with the Suffolk polled bull, with a view, 798 Derivation of the Domestic Polled Breeds. mainly, no doubt, to improve the milking qualities of the breed, as well as to do away with the horns. Since then this old Norfolk breed seems to have died out. But the old Suffolk breed survives pure in one peculiar variety—a cow of golden yellow. Of course there are various shades of this color, but the real golden yellow is, to my mind, the most beautiful of all colors; it is sometimes seen in horses, though but very rarely. Indeed, I do not recollect to have seen more than three or four in the course of my life. How- ever, this color is not popular in cows of the Red Polled breed, nor, indeed, I believe, among Short-horns. Perhaps the reason for this - is that a pale washed-out yellow, which often occurs, gives a feeble look to an animal. i “Of the old Suffolk breed, no one pretends to have traced the origin. Perhaps, in some future day, some of the numerous old manuscripts that are being reproduced in print may throw some light on the history of this animal—at present it is purely conjec- tural. The balance of probability would point to this kind of cattle being derived from the old white breed with black or red ears and muzzles. Polled cattle of this description were formerly to be found in various parts of Suffolk and Norfolk, and some small remnants remain to this day. The transition from white to yellow would not appear to be difficult. The pictures of J. Ward, the eminent cattle and landscape painter, furnish numerous instances of the prevalence of this breed, both polled and horned varieties, whether from an artistic preference, or from an actual preponder- ance of the type, it is hard to say. I have, myself, two oil paintings by this master, one of which contains a polled and the other a horned cow of the white breed, with red muzzle and ears. The breed with black ears and muzzles and more striking in appearance from the strong contrast in color; indeed, it is hardly possible to find anything prettier than a young calf of this kind. In the National Gallery there is a large landscape of a Yorkshire scau!, with groups of cattle. In the foreground stands a white bull of very massive proportions, ears and muzzle being of a light red. 2 “The earliest descriptions of Suffolk cattle speak of them as, various colors, some cream or yellow, some brindled; others, again, as red; some as mouse-colored, or a kind of blue, but none of ap as black—in this respect differing from the Scotch Kyloes, onos Derivation of the Domestic Polled Breeds. 799 the oldest, if not the oldest, breed of cattle in the British Isles. It is certainly not a little peculiar that none of the writers of that day mention black Suffolks, more especially as some of the Suffolks had been crossed with Galloways—a breed in which black certainly pre- dominates, No doubt, at times, red Galloways have been produced from pure-bred black parents, and some were said by Youatt to be of a dun or drab color. However, I am not inclined to accept the evidence of color as a sign of purity of race.” Mr. Youatt has given it as his opinion that the Red Polls are descended from the Galloway breed ; but after a careful and impar- tial examination of the records bearing on the subject we are inclined to believe with Mr. Euren, editor of the Herd-book, that in the several varieties of Red Polled cattle we have the descend- ants of the ancient breed valued by our ancestors for their large yield of milk. This explanation of the derivation of the breed is the more probable when it is remembered that since 1765 there have been domesticated herds of white polled park cattle in Nor- folk, they having in that year been taken to Gunton, in Norfolk, from Middleton Hall, where they were maintained in a wild state long prior to 1697. These Gunton polled cattle and their offshoots me domesticated in Norfolk, were multiplied in the county, and it is almost certain that to them is chiefly due the distribution of a polled breed over the county. Arthur Young, in his survey of Suffolk, dated 1792, remarks that the cattle there “were uni- versally polled—that is, without horns.” Files of the Norfolk Mercury show that in 1774 there were whole dairies of polled cattle in the county. It is clear that the Galloway cross was also intro- duced ; but there is distinct proof that polled cattle existed in con- siderable numbers both in Norfolk and Suffolk prior to the date when the Galloways themselves became generally polled. We read in the Norwich Mercury of 1770 advertisements of polled cattle, both bulls and cows, to be sold near Cawstown, Peep- ham and Pullham market. In 1802, advertisements for the Red Polled cattle were very numerous. These Galloways are distinctly stated to have been for purposes of feeding, simply; and that they were not used for creating a horn- less variety out of already hornless cattle is evident from the total want of similarity between them, not only in color but general 800 Derivation of the Domestic Polled Breeds, resemblance. The two breeds are totally dissimilar. If there is any resemblance in general contour and appearance between the Suffolk and Scotch Poll, it is to the Aberdeen-Angus, and not the Galloway. Photographs or engravings of these two breeds are strangely similar, and might be taken for either breed, except, in reality, the color and size; while pictures of Red Polls and Gallo- ways could be distinguished at a glance. As Mr. R. E. Loftt points out, in a letter he has favored me with, “black and red are convertible colors, red Galloways being every now and then pro- duced from pure-bred black sire and dam.” But whoever heard of a black Suffolk polled cow ?—which would be bound to appear once in a while if the breed owed any origin to a black polled breed. So that “an investigation of even a very limited nature is sufficient to convince any one that the theory has been properly exploded,” “that a breed of cattle, themselves hornless from their earliest origin, needed a cross with another hornless breed in order to make them polled.” : I have carefully examined all the earliest authorities on the coun- ties of Norfolk and Suffolk that could be expected to throw light on this subject. These authorities are: Norfols—Nathaniel Kent, “General View of Norfolk,’ 1794; William Marshall, “ Rural Economy of Norfolk,” 1787; Arthur Young, 1804. Suffolk— Arthur Young, “General View of Agriculture of Suffolk,” 1794; and the following: Culley, “On Live Stock”; John Lawrence, “ Cattle”? 1805; and Richard Parkinson, “Live Stock,” 1810. The particulars given by these authorities need not be repea here. Suffice it to say—as these notes are only required to g0 so far as will establish the correct origin of the polled breeds— in none of these county reports is there any evidence to support the assertion that the Red Polls owed any origin to the Galloway Scot; in fact, “no allegation had ever been made in such well- informed quarters” to such effect. Culley appears to have been the genius who “ discovered ” this supposititious origin for a breed already polled, and Lawrence, Parkinson, Henderson, Youatt ane others have been content to serve up the same old fable without examination—thus leaving a legacy of error to the Galloway histo- rian, to his own detriment. ay As to the claims of the Galloway, therefore, as being the origm Derivation of the Domestic Polled Breeds. 801 even in part of the Suffolk, or any other polled race which were polled before they were, the position may be illustrated thus: To the name given to a certain garden weed, coltsfoot, whose flower appears before the leaves, hence called “the son before the father.” To the ideas expressed in the Rig-veda.' Indra is the principal god of the Veda, who made Heaven and Earth, and the account of whose origin is that he had “begotten his own father and mother from his own body.” “Indra begat his parents” is exactly the parallel of the claims of the Galloway. The above may be said to be all that is known at present in the best-informed quarters. I now am able to produce the last and most conclusive item of testimony to this already well-forged chain. This is derived from the “paleontology” of language; by the existence, in the good old times, of a word used in Suffolk to name the polled cattle pf the locality. That word was mooly, meaning a polled cow. It was in use, according to old English philologists, during and previous to 1750, as will be shown in the chapter on Philology. This will illustrate the value of philology as a source ofevidence. It occupies a similar and as exact a position as “the testimony of the rocks.” That the word was of Suffolk use in England and was a household word in those days is incon- testible. It is therefore curious to know that it seems extinct now, or unknown to such a widely informed student as Mr. G. Gilbert, for in answer to my query he informed me he was totally unaware of any local or provincial word used in the way indicated. The very near equivalents of the word, as in the Irish and Gaelic maol, and north of Scotland mooly, will be commented on again, and they suggest important reflections. The fact of the use of this word in these days in Suffolk is Proof sufficient of the great antiquity of the cattle the word described —an antiquity much greater than of a breed that never had any such cognomen —as the Galloway. But I offer another proof of the worth of this link of evidence as satisfying our requirements in that respect. Let us jump over to America, What do we find? That this same word mooly is in Bio ey of the Rig-veda. By H. W. Wallis. Published by India, lle Williams and Norgate, London. nals. at does it Teach us? By Max Miiller. Funk and Wag- 802 History of Garden Vegetables. universal, living, use to describe the polled cow in all her various forms. Mr. Euren, in his history of the breed in the Red Polled Herd Book, Vol. I., very evidently was perfectly unconscious of the fact of the claims of the word mooly to being an early Suffolk provin- cialism. If he had, how more positive would have been the remark- able'query he makes—showing how close his “ speculation ” came to real exactitude ;—note he uses marks indicating the “ foreign” use of the word: “‘Muley’ cattle have been in Virginia for a great many years, and their descendants have also been uniformly polled. . . . It would be of value to the students of the history of cattle were search to be made respecting the introduction of polled stock into America. It is recorded that many of the earlier settlers were natives of Norfolk and Suffolk villages. May they not have taken over polled cattle, which at that day were so numerous in Suffolk and on the Norfolk borders?” He does not suggest that these settlers, if they did not—the first of them—take polled cattle, took the word mooly with them ; and, finding that the cattle there, of various origins, then or subsequently introduced, frequently coming polled, applied the word to them they had been accustomed to.

The kales represent an extremely variable class of vegetable, and have been under cultivation from a most remote period. What the varieties of cabbage were that were known to the ancient Greeks it . seems impossible to determine in all cases, but we can hardly ques- tion but that some of them belonged to the kales. Many varieties were known to the Romans. Cato,! who lived about B. c. 201, describes the Brassice as: the levis, large, broad-leaved, large- stalked ; the crispa or apiacon ; the lenis, small-stalked, tender, but rather sharp-tasting. Pliny,? in the first century, describes the Cumana, with sessile leaf and open head; the aricenwm, not excelled in height, the leaves numerous and thick ; the Pompeianum, tall, the stalk thin at the base, thickening among the leaves; the Bru- tiani, with very large leaves, thin stalk, sharp savor; the Sabellica, admired for its curled leaves, whose thickness exceeds that of the stalk, of very sweet savor ; the Lacuturres, very large headed, innumerable leaves, the head round, the leaves fleshy; the Triti- anon, often a foot in diameter, and late in going to seed. - I have not sufficient knowledge to give a complete history of the kales. I can only review those races which I have had an oppor- : tunity of studying, and this I will make as short as possible, intending only to bring into form for further study. I. The form of kale known in France as the Chevalier seems to have been the longest* known, and we may surmise that its names of chou caulier and caulet have reference to the period when the word caulis, a stalk, had a generic meaning applying to the cabbage Tace in general, and we may hence surmise that this was the com- mon form in ancient times, in like manner as coles or coleworts in more modern times imply the cultivation of kales. This word coles or caulis is used in the generic sense, for illustration, by Cato, Ie Script. Rei Rust., 1787, vol. i., p. 75. ie ee Lib. xix., c. 41; Lib. xx., c. . - P. Decandolle.

In addition to the above we may mention the proliferous kales, which also occur in several varieties.

The Dwarf Kales—Decandolle does not bring these into his classification as offering true types, and in this perhaps he is right. Yet olericulturally considered they are quite distinct. There are but few varieties. The best marked is the Dwarf Curled, the leaves falling over in a graceful curve and reaching the ground. It can be traced through variations and varieties to our first class, and hence it has been probably derived in recent times through a pro- cess of selection, or through the preservation of a natural varia- tion. We have now an intermediate type between the Dwarf Curled and the Tall Curled forms in the intermediate Moss Curled. 808 On Certain Factors of Evolution. III. The Portugal Kales—We have two sorts of kales that have the extensive rib-system and the general aspect of the Portugal cabbage. These are the Chou Brocoli and the chou frise de mos- bach of Vilmorin. I must consider these as bearing the same rela- tion to the Portugal cabbage that our kales bear to the heading cabbages. Of their history I have ascertained nothing. ON CERTAIN FACTORS OF EVOLUTION.' BY ALPHEUS. S. PACKARD. S° far as we are aware, Lamarck was the first naturalist to refer the atrophy of eyes and loss of vision to disuse from a life in darkness, as may be seen by the following extract from the chapter in his Philosophie Zoologique, entitled “ De V’influence des circon- stances sur les actions et les habitudes des animaux, et de celle des actions et des habitudes de ces corps vivans, comme causes qul modifient leur organisation et leurs parties.” This work appeared in 1809, many years before the discovery of blind animals peculiar to caves. f “ Des yeux à la tête sont le propre d’un grand nombre d’animaux divers, et font essentiellement partie du plan d’organisation des vertébrés. Déjà néanmoins la taupe, qui, par ses habitudes, fait trés-peu d’usage de la vue, n’a que des yeux trés-petits, et à peine apparens, parce qu’elle exerce trés-peu cet organe. “ I’ Aspalax d’Olivier (Voyage en Egypte et en Perse, I, pl. 28, fig. 2), qui vit sous terre comme la taupe, et qui yraisemblable- ment s’expose encore moins qu’elle A la lumière du jour, a totale- ment perdu Vusage de la vue ; aussi n’offre-t-il plus que des vestiges de l’organe qui en est le siège ; et encore ces vestiges sont tout-à-fait cachés sous la peau et sous quelques autres parties qui les recouvrent, et ne laissent plus le moindre accès à la lumière. “Le protée, reptile aquatique, voisin des salamandres par 88 rapports, et qui habite dans des cavités profondes et obscures qu 1 From advance sheets of an essay on Cave Animals of North America. Mem. Nat. Acad. Sciences, On Certain Factors of Evolution. 809 sont sous les eaux, n’a plus, comme |’Aspalax, que des vestiges de Porgane de la vue; vestiges qui sont couverts et cachés de la même maniére, “Voici une considération décisive, relativement à la question que j’agite actuellement. “ La lumière ne pénètre point partout ; conséquemment, les ani- maux qui vivent habituellement dans les lieux où elle n’arrive pas, manquent d'occasion d’exercer l’organe de la vue, si la nature les en a munis, Or, les animaux qui font partie d’un plan d’organisa- tion, dans lequel les yeux entrent nécessairement, en ont df avoir dans leur origine. Cependant puisqui’on en trouve parmi eux qui sont privés de usage de cet organe, et qui wen ont plus que des vestiges cachés et recouverts, il devient évident que Vappauvrisse- ment et la disparition même de l’organe dont il s’agit sont des résultats, pour cet organe, d’un défaut constant d’exercice (2d edit., i, p: 241).” In his “ Origin of Species” Darwin, after claiming that “natural selection would constantly aid the effects of disuse” in the case of moles and the burrowing rodents, then remarks in regard to cave animals: “ As it is difficult to imagine that eyes, though useless, could be in any way injurious to animals living in darkness, I attribute their loss wholly to disuse” (p. 142). On the next page he writes: “By the time an animal had reached, after numberless generations, the deepest recesses, disuse will on this view have more or less perfectly obliterated its eyes, and natural selection will often have effected other changes, such as an increase in the length of the antenne or palpi, as a compensation for blindness.” It may be that the struggle for existence goes on even in the darkness of caves, and that the “ fittest” of the limited population survive by reason of their adaptation to their untoward surround- ings. How adverse to life of any sort caves are may be realized when we consider that only the lowest plants, and only a very few of those, live in caves, Without doubt the germs of fungi and the seeds of the higher plants are carried into the caves by freshets in subterranean streams and through sink-holes. Why, in spite of darkness, we should not find more fungi even, and why one or two of the green alge should not flourish in the pools and brooks of caves, or why the seeds of the higher plants should not germi- 810 On Certain Factors of Evolution. nate, even if the plants do not bear fruit, can only be explained by the absence of light ; and perhaps this is an important cause of the absence of all plant life in the ocean below a depth of about 300 to 500 fathoms, Certainly there are ample means for the colonization of caves by vegetables; the temperature, moisture, and inorganic food are more favorable than the sum total of conditions on alpine summits or in the high polar regions, or in hot springs. Animal life can apparently withstand greater physical obstacles than vegetable. As regards the struggle for existence, it possibly exists to a limited extent in cave animals. There is probably not enough vegetable or decayed animal food for all the animals, and some may die of hunger. The carnivorous beetles and Arachnida perhaps have a less favorable chance to obtain living food than the Crustacea, for the blind crayfish have a tolerable abundance of food in the Cæcidotæa, perhaps the most abundant form found in caves containing underground waters. We may, with Darwin, for convenience, use the phrase “ natural selection ” to express the process by which Whe cave fauna was pro- duced, but such a term to our mind expresses rather the result of a series of causes than a vera causa in itself. There is of course no doubt but that many animals carried by different means into caves cannot thrive there, and consequently die. It is only those which have been able, by certain peculiarities of their life in the upper world allied to cave existence, to adapt themselves to cave conditions which permanently breed there. Such forms, it is con- venient to say, have been by nature selected and are successful in colonizing the darkest and most forbidding and apparently hopeless corners in the earth’s crust. But such a phrase as “ natural selec- tion,” we repeat, does not to our mind definitely bring before us the actual working causes of the evolution of these cave organisms, and no one cause can apparently account for such a result. There is rather a complex assemblage of physical causes, all working together, to secure a harmonious result. The most important and potent of these causes, when we study them under such appreciable, because so extraordinary, conditions as the physical features of cave existence, would seem to be the following : os 1. Change in environment from light, even partial, to twilight or total darkness, and involving diminution of food, and compensa- tion for the loss of certain organs by the hypertrophy of others. On Certain Factors of Evolution. 811 2. Disuse of certain organs. 3. Adaptation, enabling the more plastic forms to survive and perpetuate their stock. 4. Isolation, preventing intercrossing’ with out-of-door forms, thus insuring the permanency of the new varieties, species, or genera. 5. Heredity, operating to secure for the future the permanence of the newly originated forms as long as the physical conditions remain the same. Natural selection perhaps expresses the total result of the working of these five factors rather than being an efficient cause in itself, or at least constitutes the last term ina series of causes. Hence Lamarckism in a modern form, or, as we have termed it, Neo- lamarckism, seems to us to be nearer the truth than Darwinism proper or “ natural selection.” The factors of organic evolution such as we have mentioned are, of course, theoretical, and the critic or unbeliever in a theory of descent demands facts in demonstration of the truth of the deriva- tion of cave animals. Of the facts we have ourselves observed, or which have been observed by others, we will briefly summarize :— 1. The variations in Pseudotremia cavernarum and Tomocerus eet found living near the entrance of caves in partial day- ight. 2. The bleaching of Polydesmus and Machilis found living in small caves; the blindness of Neotoma, or the wood-rat of Mam- moth Cave; of fish found in wells and subterranean streams; the atrophy of the mole’s optic nerves induced in one generation. 3. The larger size of the eyes of the young than in the adult Troglocaris of Europe, and the blind crayfish of American caves; Semper’s history of the atrophy of eyes in the parasitic Pinnothe- res; eyes of Gammarus pulex affected after living in darkness; the eyes of Gammaride in Lake Baikal becoming smaller the deeper they live; the instability in the eyes of Cæcidotæa. Tn a small cave near White’s Cave, and at a point about sixty feet from the mouth, occurred a salamander (Spelerpes longicauda- tus Green), which was apparently bleached, being nearly white, with dark brown blotches. The common Cambarus bartonii occurs some- what bleached in Mammoth Cave, and this may not be the result 812 On Certain Factors of Evolution. of inheritance, but occurs in young hatched without the cave, and afterwards carried in so as not to be exposed to the light, the shell remaining pale as in the very young. Perfectly white, bleached specimens of the common Polydesmus granulatus Say, occurred in Indian Cave. The pale variety of Tomocerus plumbeus is possibly the product of a single or at least very few generations; the white and blind Porcellio found by Mr. Hubbard in Little Wyandotte Cave, though possibly a true cave form, has not yet been found elsewhere, and may have been the young of a normal, epigean spe- cies. But the most striking instance is the bleached specimen of Asellus communis from Lost River, referred to on pp. 15 and 33, which, though white, had eyes of normal size: there is good reason to suppose that these specimens were hatched in epigean waters, and that being carried into Lost River when young, the pigment in its skin, owing to absence of light, had failed to assume its normal dark color. A parallel case is that mentioned by R. Schneider*:— “The author gives an account of the subterranean variety of Gammarus pulex which is found at Clausthal. The first point of interest is its pale color, pigment being so completely absent from its body that it is milk-white and transparent; even the fat-cells, which are intensely red or orange-yellow in the ordinary G. pulex, are quite white. In the second place, the eye is not normally devel- oped, but is in the first stage of reduction; the crystalline cones show signs of degeneration, and the whole eye exhibits that ‘ meg- alophthalmy,’ or proportionately greater size which is often the first indication of loss. The pigment has also begun to be reduced, and is of a dirty black, instead of a brownish color. The anterior pair of antennæ exhibits elongation, owing to the increase in the number of the joints. “There is, as compared with the ordinary forms, a considerable increase in the amount of calcareous deposits; and there is always a considerable amount of iron-oxide in the contents of the intestin®, whence the iron makes its way to various parts of the body. “ Fries? suggests that experiments should be made on the eltec™ 1 Unterirdische Gammarus von Clausthal, P.

Fries also states that he himself had previously observed a decrease in the pigment of the eyes in young examples of Gammarus pulex living in darkness.” Here should be cited the observations of Anton Stecker, who states that Chermes, usually said to be eyeless, has rudimentary eyes, represented by clear, somewhat transparent spots, the chitin forming them being devoid of the granulations covering the rest of the shield, “ Each cornea is supplied by a large and well-developed optic nerve, proceeding from an optic ganglion in connection with the brain. But the layer of crystalline rods was wholly absent. About 30 to 35 per cent. of the specimens of Chermes cimicoides examined possessed these eye-spots; in the remaining 65 to 70 per cent. they were absent, as well as the optic nerves; while there was only one, or even no recognizable rudiment of an optic ganglion. He also found that the offspring of parents, both of which had eyes, were themselves provided with them; but that if either the father or the mother were blind, the young were also blind, having at most a feeble indication of optic lobes. Dr. Stecker considers this a most instructive case of the gradual atrophy of an organ by disuse owing to the influence of changed conditions. There can be little doubt that the ancestors of Chermes possessed well-developed eyes; the first steps in the retrogressive process was the loss of the cornea and cones, the optic nerve and ganglion remaining after the true percipient apparatus had gone.” ! Here is a fertile field for careful and long-continued observa- tions on animals reared in different degrees of darkness. Such experiments will afford a crucial test of the theory of rapid evo- lution of genera and species due to sudden changes in the environ- ment, It is evident that physiological experiments are needed as well as embryological studies, to throw further light on the origin of cave animals, The blind-fish, blind crayfish, and Cæcidotæa, 1 Morp. Jahrbuch, iv., 279, 1878; Journ. Roy. Mier. Soc., ii., 146, 1879. 814 On Certain Factors of Evolution. which might be reared in dark cellars, should be observed for a series of generations, to ascertain whether by breeding the eyes cannot be restored, and the species by artificial means be induced to revert to its ancestral type. The embryology of the cave bee- tles, with or without rudimentary eyes, of the eyeless spiders and of Myriapods, of the Cæcidotæa, and of the blind crayfish and blind- fish should be carefully worked out as regards the presence of organs of vision in a rudimentary state, though we should hardly expect to find rudimentary eyes in Anophthalmus when larva and pupa do not possess them. Isolation as a Factor in the Origin of Cave Animals.—When any cave, such as Mammoth or Wyandotte, ete., is once colonized by emigrants from the upper world, and the colonists becoming adapted to the new conditions environing them, have lost their eye-sight, or even all traces of eyes, and the new forms thus established begin to breed true to their recently acquired characteristics, it 18 obvious that this process of in-and-in breeding will continue as long as the new forms live in total darkness and are isolated from the allied forms or their eyed ancestors of the upper world of light. Though a subordinate factor, isolation is certainly of no little import- ance in securing the stability of the new species and genera. It is evident that if no stragglers from the upper world, as species of Trechus to interbreed with the cave Anophthalmi, species of Cho- leva to cross with Adelops or Bathyscia, or species of Ceuthophilus to mix with the true cave Ceuthophili, or species of Myriapods or Arachnida to intercross with the cave forms, then the latter will tend to remain as fixed as we now find them to be. In the case of the crayfish of Mammoth Cave, the normal Cambarus bartoni, introduced at times of heavy rains or freshets into the cave, ® not seldom found living in company with Orconectes pell the blind form, but belonging to a different section of the genus 4 regards the shape of its gonopods or first male abdominal appen- dages, and being of much larger size, it is probably incapable of fertilizing the eggs of the blind form, even if the latter, timid sensitive to the least disturbance of the water, should allow itself to be approached by the larger-eyed form. It is also probable that Cæcidotæa stygia is seldom, if ever, brought in contact with Asellus communis, which abounds in the pools and streams through- On Certain Factors of Evolution. 815 out the cave region. I have never found a stray Asellus even partly bleached and with diminished eyes in any caves, nor seen such specimens in collections made by others, though they may yet be found. Whether living in caves or wells fed by subter- ranean streams, the bleached, eyeless, or nearly eyeless, forms breed true to their type, and show no signs of intercrossing with luco- philous forms. Should, however, these cave forms be placed in such circum- stances as to be able to mix or intercross with their epigæan allies, which are in all probability the very species to which they owe their origin, there would with little doubt be a constant tendency to revert to the ancestral eyed forms, and we should constantly find certain individuals with visual organs better developed, and with a darker integument, serving as connecting links, Such links may have been common enough when the caves were first formed and colonized, and in some species, as Pseudotremia cavernarum, they frequently occur at the present time, but, as a rule, owing to lon isolation or seclusion, and the consequent impossibility of intercross- ing, they are now rare. But as circumstances are now, the total darkness, the temperature, the degree of dryness or the moisture, and other physical conditions remaining the same, the eave fauna is almost completely isolated from that of the upper world; indeed, far more so than the deep- sea fauna of the ocean or of lakes, or the faunas of deserts or of the polar regions, or the alpine inhabitants of lofty mountain summits. We thus realize that isolation may be a not unimportant factor in securing permanence of type, after the typical characters have once been established through adaptation and heredity. After reflecting upon the influence of isolation upon cave animals as securing permanence of varietal, specific, and generic characters, one is led to realize as never before the importance of geographical isolation in general as a faetor in preventing variation after the organisms have once become adapted to their peculiar environment, whether dependent on temperature, soil, humidity, or dryness, the absence of light, or any other appreciable characteristic in their Surroundings. We know also that the existing desert, deep-sea, and polar faunas are the product of Quaternary times; that they Were nearly contemporaneous in origin with the cave faune, 816 On Certain Factors of Evolution. though the deep-sea faunæ may date from the cretaceous period. Finally, I may quote from Darwin’s “Origin of Species” the following extract, which applies (though he did not make it appli- cable to any special case) with peculiar force to cave fauna: “ If, however, an isolated area be very small, either from being sur- rounded by barriers, or from having very peculiar physical condi- tions, the total number of the inhabitants will be small, and this will retard the production of new species through natural selection, by decreasing the chances of the appearance of favorable individual differences ” (Fifth edition, New York, p. 105). Heredity.—The action of this all-powerful factor in evolution is as constant in the underground world, and as difficult to compre- hend in considering cave life, as that of the upper regions. It begins to act, of course, with the earliest generations, and continues to act with, so to speak, increasing force and precision as time goes on and the characteristics induced by a life in total darkness becomes more and more fixed. It is evident that heredity has acted longest in those insects, such as the species of Anophthalmus and Adelops, whose larve are lacking in all traces of eyes and optic nerves and lobes. Heredity has here acted with unabated force throughout every stage of the metamorphosis ; and, it will be a matter of great interest to ascer- tain whether any traces of the eyes"*may be met with in the embryo of these forms, On the other hand, in those Arthropods in which the brain and optic nerves have persisted, with rudiments of the eyes (eg, Orconectes), where the eyes are larger in the young, it would seem as if heredity had been acting through a shorter period, and conse- quently, so to speak, with less momentum. In the case of Machærites, in which the females only of certain species are said to be blind, while the males have well-developed eyes, we have an apparent exception to the continuous action ° heredity ; an exception paralleled, however, by animals living ” the upper world, such as Termes, whose workers and soldiers are eyeless, though the males and females are eyed. They per haps are twilight species rather than inhabitants of totilly dark localities in caves, and those living in twilight may intercross with those On Certain Factors of Evolution. 817 inhabiting the darker regions, and such a case as this, remarkable as it would appear, does not affect the general rule, that animals living in total darkness and never living in twilight, nor inter- crossing with twilight forms, are eyeless, or at least blind. Nor does the case of Hadencecus, the cave cricket, with well- developed eyes and brains, affect the argument ; for this is essen- tially a twilight form, though migrating to regions of total darkness and abounding there. The same may be said of the cave species of Ceuthophilus. A parallel case may be that of Chologaster as compared with Amblyopsis, the former living out of caves in ditches as well as in wells and caves. J udging by the following statement, so eminent a naturalist as Professor Semper denies that heredity acts in the case of the mole. He says; : “ This almost total blindness in the mole is the result solely of complete degeneration of the optic nerve, so that the images which are probably formed in the eye itself can never be transmitted to the animal’s consciousness. Occasionally, however, the mole even can see a little, for it has been found that both optic nerves are not ways degenerate in the same individual, so that one eye may remain in communication with the brain while the other has no connection with it. In the embryo of the mole, however, and without exception, both eyes are originally connected with the brain by well-developed optic nerves, and so theoretically efficient. This may indeed be regarded as a perfectly conclusive proof that the blind mole is descended from progenitors that could see ; it would Seem, too, to prove that the blindness of the fully grown animal is the result not of inheritance, but of the directly injurious effects of darkness on the optic nerve in each individual.” } It may be objected, however, that each mole certainly inherits a tendency to weakness and atrophy of the optic nerves, just as the children of consumptive or strumous parents inherit a tendency to those diseases, and that when the conditions are favorable the disease manifests itself. We know there have been many generations of blind or partially blind moles, and it would be strange if heredity did not ata certain age act in such a case, and would not for at least a few generations even if the moles were kept out of the dark- 1 Animal Life, etc., pp. 79, 80. é 818 On Certain Factors of Evolution. ness. We have in the atrophy of the optic nerves of the mole a parallel case in the blind Myriapod Pseudotremia cavernarum, where the eyes survive but the optic nerve is wanting, as also in a less marked degree in some of the individuals of Cæcidotæa stygia. The study of the conditions of existence in caves is of special value, because such conditions are so unusual and abnormal and the results upon certain organs so easily appreciated. It is by a study of life under unusual conditions that the attention is aroused and interest is excited, and after acquiring experience in dealing with the more palpable, because somewhat abnormal, circumstances under which organisms exist, we can then more easily observe the effects of changes of ordinary conditions upon the organism. From a study of cave life, of organisms existing in saline and in heated waters, of plants and animals. exposed to great cold in alpine or polar regions, of those living in hot, dry deserts, we can turn to an examination of the results of adaptation to a parasitic mode of life. The strange modifications of form, owing to disuse, in internal as well as external parasites of different orders and classes, the change of host necessitated, and the intensity of the struggle for existence in animals living under such exceptional conditions, embryology proving that they have arisen from animals of normal organization,—such studies as these are of fundamental importance in a discussion of the origin of species and higher categories. Moreover, the study of the results of the incoming and cessation of the Glacial epoch, the effects on life arising from the elevation and depression of the land, involving not only change of land surfaces, but a change of climate,—it is by a study of such marked changes as these in the conditions of life that we are prepared to examine the more subtle causes of variation throughout the organic world in general, After the foregoing pages were written we read with much interest Mr. Herbert Spencer’s recent essays entitled “The Factors of Organic Evolution.”! While that author, it appears to Us, lays too great stress on Dr. Erasmus Darwin’s views, as compared with Lamarck’s ; the author of the Philosophie Zoologique having been a professional botanist and zoologist as well as a naturalist of the 1 New York, 1887, reprinted from the Nineteenth Century for April and May, 1886, On Certain Factors of Evolution. 819 first rank, it is noteworthy that he sees clearly that natural selection is not the sole factor in organic evolution, as will be seen by the general drift of his essays, by his quoting with approval Huxley’s significant remark that “Science commits suicide when it adopts a creed,” and by the following extracts from his own essays :— “But now, recognizing in full this process brought into clear view by Mr. Darwin, and traced out by him with so much care and skill, can we conclude that, taken alone, it accounts for organic evolution? Has the natural selection of favorable variations been the sole factor? On critically examining the evidence we shall find reason to think that it by no means explains all that has to be explained” (p. 9), During that earlier period, when he was discovering the multitu- dinous cases in which his own hypothesis afforded solutions, and simultaneously observing how utterly futile in these multitudinous cases was the hypothesis propounded by his grandfather and Lamarck, Mr. Darwin was, not unnaturally, almost betrayed into the belief that the one is all-sufficient and the other inoperative.! But in the mind of one usually so candid and ever open to more evidence there naturally came a reaction. The inheritance of functionally produced modifications, which, judging by the passage quoted above concerning the views of these earlier inquirers, would seem to have been at one time denied, but which, as we have seen, was always to some extent recognized, came to be recognized more and more, and deliberately included as a factor of importance. In his references to the works and opinions of other naturalists Mr. Spencer confines himself almost exclusively to those of Mr. Darwin, who always opposed, and, it must be confessed, with less than his usual candor and fairness, the views of Lamarck as to the influence of a change in the environment upon organisms.” It seems singular that Mr. Spencer should not be acquainted 1 It is surprising to read in Darwin’s Life, by his son, the expressions showing his lack of appreciation of Lamarck and his work; Darwin seems m the first to have been strongly prejudiced against Lamarck’s views, and never to have done them justice. * In the Origin of Species (p. xiv., note) Darwin writes, as quoted by Spencer: “It is curious how largely my grandfather, Dr. Erasmus Darwin, anticipated the views and erroneous grounds of opinion of ago tg in his ‘Zoonomia’ (vol. i., pp. 500-510), published in 1794” p. Je 820 On Certain Factors of Evolution. with the work of those who have brought together certain facts bearing on the physical factors of evolution.! The principal fac- tors referred to by Mr. Spencer are use and disuse and the influence of light. In one place he does in concrete language sum up these agencies as follows :— “The growth of a thing is effected by the joint operation of certain forces on certain materials; and when it dwindles there is either a lack of some materials or the forces co-operate in a way different from that which produces growth. ... . That is to say, growth, variation, survival, death, if they are to be reduced to the forms in which physical science can recognize them, must be expressed as effects of agencies definitely conceived—mechanical forces—light, heat, chemical affinity, etc.” (pp. 39, 40). On page 70 Mr. Spencer remarks :— “ But nevertheless, as we here see, natural selection could operate only under subjection. It could do no more than take advantage of those structural changes which the medium and its contents initiated.” Again, on page 73, Spencer suggests that natural selection, 1m order to act, must have had a limited number of organisms upon which to operate? As he remarks :— : “Though natural selection must have become increasingly active when once it had got a start, yet the differentiating action of the medium never ceased to be a co-operator in the development of these first animals and plants.” : In the writer’s Introduction to the Standard Natural History, 1885, under the head of Evolution (pp. 1 and Ixii.), he has endeavored to bring together references to the different authors who have insisted on ee which are in the line of those first suggested by Lamarck, @ phase : evolution which we have called Neolamarckianism.

Editors’ Table. 821 Finally, Mr. Spencer makes the following important admission :— “This general conclusion brings with it the thought that the phrases employed in discussing organic evolution, though conve- nient and indeed needful, are liable to mislead us by veiling the actual agencies. That which really goes on in every organism is the working together of component parts in ways conducing to the continuance of their combined actions in presence of things and actions outside, some of which tend to subserve and others to destroy the combination. The matters and forces in these two groups are the sole causes properly so called. The words ‘ natural selection’ do not express a cause in the physical seuse. They express a mode of co-operation among causes, or rather, to speak strictly, they express an effect of this mode of co-operation ” (p. 40). Here we have frankly intimated what the Neolamarckian has for years insisted on, that the phrase “ natural selection” is not a vera causa, but rather expresses the results or effects of the co-operation of a number of factors in organic evolution. In the case of too many naturalists the dogma or creed of natural selection has, it Seems to us, tied their hands, obscured their vision, and prevented their seeking by observation and experiment to discover, so far as human intelligence can do so, the tangible, genuine, efficient actors of organic evolution. EDITORS’ TABLE. EDITORS: E. D. COPE AND J. S. KINGSLEY. The bringing into cultivation of the arid regions of the United States would increase the agricultural resources of the nation by one-third. The man who should devise a successful method of doing this would be one of the benefactors of his kind and country. The region to be thus reclaimed includes a wide strip extending north and south, east of the Rocky Mountains; a large part of the drainage basin of the Rio Grande; the hydro- graphic basin of the Great Colorado, and the Great Basin of Utah and Nevada, Small portions of all these regions are at present 822 Editors’ Table. rendered productive by irrigation, and give an earnest of the great possibilities which await the entire region. The productiveness of the Great Basin of Utah and Nevada would be equal to that of the most favored of temperate regions of the earth were water only accessible, as the results of irrigation by the Mormons and others have demonstrated. The attempt to supply the lack of water by artesian wells has proven successful only in limited localities, and it has been long evident that some other source of supply must be looked for. Major J. W. Powell having given the subject his attention for many years, has at leached a solution as nearly adequate as the circumstances permit. He has proposed to Congress that the U. S. Government dam up the waters of the streams and rivers which issue from the various Rocky Mountain ranges, and thus accumulate their waters for a wholesale system of irrigation. an There appears to be nothing impracticable about this proposition. The manner in which the rivers issue from the Rocky Mountains in narrow canyons seems to be well adapted for the execution of such an enterprise. The artificial closing of the canyons of the Platte and Arkansas on the east, of the Rio Grande on the south, and of the Green and Gunnison on the west, would seem to present no great engineering difficulties, and immense bodies of water would be thus secured for purposes of irrigation. The benefits to agri culture resulting would be immense, and regions now almost useless to mankind, would become well populated. Some large regions would, however, not be reached by this system, especially a great part of the Great Basin. ; Congress has appropriated $100,000 towards this important project, to be expended under the direction of Major Powell. Pcs observe with pleasure that Major Powell regards this enterprise ~ entirely distinct from the U. S. Geological Survey. We hope he will continue to resist the attempt of some members of the ghee House to saddle the expense of this undertaking on the Geology Survey ; otherwise we will have another and gigantic illastrase® of a purely scientific enterprise swamped by the utilitarianism which is so rampant and all-absorbing in this country. Geography and Travel. 823 GENERAL NOTES. GEOGRAPHY AND TRAVEL! Asta.—Lieut. Younghusband’s journey through Central Asia and over the Mustagh Pass.—Subsequent to his sojourn in Man- churia, in company with Messrs. Fulford and James, Lieut. Young- husband undertook, and successfully accomplished, an adventurous Journey across Central Asia and thence into Hindostan by way of the Mustagh Pass, which had not previously been crossed by any European. His route from Pekin to Chinese Turkistan was the steppes. The Great Wall, which isa magnificent affair near Pekin, has on the Mongolian frontier dwindled to a miserable mud wall hot twenty feet high, with gaps in it often from a quarter to half a mile in width, Che Mongols, though a strong and hearty people, are said to have entirely lost their old warlike spirit, largely in consequence of the policy of the Chinese Government, which encourages the males to me Lamas. Sixty per cent. of the men are said to be now - enrolled among these non-fighting celibates. Chinese immigrants are Invading Mongolia as they have done Manchuria, and are taking to Mongolian habits sufficiently to, in some cases, fatten sheep for e Pekin market. At Kuei-hua-cheng, an important place of trade with Mongolia, camels were hired for the transit of the desert to Hami. After crossing the Galpin Gobi, Mr. Younghusband passed along the southern part of the Hurku Hills, crossing Pre- Jevalsky’s route at the Bortson well. For 190 miles the way lay Over a pan lying between the Hurku range and a similar but rather lower range to the south of it. Near the end of the Hurku range, which here attains a height of about 8,000 feet, there is a 1 Edited by W. N. Lockington, Philadelphia, Pa. 824 General Notes. curious line of sand-hills attaining a height of 900 feet, and some forty miles in length, evidently formed by the wind driving the desert sand up into the hollow between the two rocky ranges. depression of about eighty miles separates the Hurku range from the out-lying spurs of the Altai. The Altai range is here perfectly barren, the upper part formed of bare rock, while the lower is a continuous slope of débris. The cold winds of winter and the fierce, sun of summer crumble the rocks, but the lack of rainfall causes the fragments to lie where they fall. After crossing the desert of Dzungaria, the Tian-Shan range was traversed at a height of 8,000 feet above the sea. The 1,255 miles between Kuei-hua-cheng and Hami were accomplished in seventy days. From Hami the ei passed through Pichan, Turfan, Karashar, Kuchar, Aksu, and Us Turfan, along the valley of the Aksu river, across the Belowti Pass (11,000 feet) and over the plain called the Syrt, to Kashgar, and thence to Yarkand. Here Lieut. Younghusband determined to attempt the Mustagh Pass, which is the shortest way into Kashmir, but has latterly fallen into disuse because of the raids of the Kanjut robbers. The Tupa Dawan Pass, a very easy one, 10,400 feet high, was crossed, and the valley of the Tisnaf, a tributary of the Yar- kand, ascended. The next pass was that of Chiragh Saldi, after which the valley of the Yarkand was reached. This river here ows due west, but afterwards turns north to Yarkand. On leaving Yarkand the party ascended the Surukwat stream to the Aghil Dawan range, which, after passing two more gorges, rose like a wall in front of them. Fortunately they struck the right path, and after some winding among the spurs, crossed the ia through a great gap, over a long gravel slope. From a hill beyon the summit of this pass, standing at a height several hundred ve above the top of Mont Blanc, the great Karakoram or Musta range, forming the water-shed between the rivers that flow into the Indian Ocean and those of Central Asia, was visible as a succession of needle peaks like hundreds of Matterhorns, rising several ee sands of feet higher still. Mr. Younghusband estimates the Ag te Dawan range at some sixteen to seventeen thousand feet. From 1 he descended to the Shaksgam river, hitherto unknown to An phers, though nearly equal in volume to the Yarkand, of whic v is a tributary. Leaving this river, the Sarpo Laggo, 4 strea d flowing from the glaciers of the Mustagh Pass, was ascended, a soon a full view was obtained of the second highest mounta 3 the world, then known only by the surveyors’ designation of x but since named by Gen. J. T. Walker, Peak Godwen-Awet : At this point serious difficulties commenced. There are two a tagh Passes, The new one, which had been found after the a donment of the old pass on account of the accumulation of sige ound to be impassible for the same reason, so an attempt was Geography and Travel. 825 to cross by the old pass, leaving the ponies behind. Through deep soft snow, ata level of 19,000 feet, the travelers labored on till they reached the summit, whence no way of descent appeared save by crossing an icy slope to a cliff too precipitous for ice or snow to lodge upon it, and by descending this cliff to more icy slopes below it. By making a rope out of every available material, and by hewing steps, the descent was at last accomplished without serious accident, only to find themselves on an extensive glacier full of crevasses. At night they emerged upon a dry spot, but on the next day they crossed the great Baltoro Glacier, and it took two days more before they reached the village of Askoli. Supplies were sent back to the coolies with the ponies, and seven weeks later this part of the caravan reached Skardo by the Karakoram Pass route. Arrica.—Brrrish Basuro Lanp.—The August issue of the Proceedings of the Royal Geographical Society contains a map and an account of that part of Basuto Land that was saved to the Basuto in 1868. It is bounded by the Orange Free State, Natal, and Cape Colony. From the first of these it is divided for 130 miles by the Caledon river, and the country between this stream and the Dra- kensberg has been known to Europeans for some fifty years, while the larger section of the district, comprising the basin of the head- waters of the Orange river, has been little explored. The Drakens- berg, which continues northward from Basuto Land into the Trans- vaal, appears to have originally been a sandstone plateau eight to ten thousand feet in height, the upper ‘stratum of coarse friable rock sloping to the south and west, but falling away in perpendicular cliffs to the eastward.

Mr. J. THomson’s TRAVELS IN Morocco.—Mr. Joseph Thomson is now traveling in Morocco, where by cleverly-planned excursions he has entered the mountain fastnesses and done more than any previous traveler. From Demnat he made two interesting trips into the lower ranges, and visited some remarkable caves and ruins, as well as one of the most wonderful natural bridge-aqueduets in the world. He then made a dart across the main axis of the Atlas to the district of Tiluit in the basin of the Draa. As the tribes further west were in revolt, he was compelled to return to the northern plains. He then crossed the mountains by a pass a little south of Jebel Tizah, and reached the Gindafy safely. After a trip up a wonderful cafion, and the ascent of a mountain, whence the party were compelled to return, though by a new route, to their starting point. Mr. Thomson again crossed the mountains, and with no small difficulty and danger ascended the highest peak of the Atlas range north of Amsiviz, to a height of 12,500 feet. He then returned to Morocco, whence he wrote to the London Times on July 22. He proposes to make his way up the Urika river, and to work round to Mogador. . Tur GERMAN East AFRICAN PossEsstons.—The Mittheilungen of the Vienna Geographical Society for June has an article by Dr. Hans Meyer on the German East African Protectorate, which is said to comprise the East African coastlands, terraces, and plateaus for a distance north and south of 550 miles, and east and west of 150 miles. The southern boundary is the Rovuma river, and a con- ventional line run from thence to Lake Nyassa, while to the north it is conterminous with the British Protectorate, from which it 18 separated by a line passing from Lake Victoria Nyanza in an oblique direction along the north foot of Kilima-njaro to the ee at about 5 S.

Frencu Guiana.—M., Coudreau, who has recently returned to Cayenne, after a sojourn of eleven months in the western Tumac- umac range, between the sources of the Itany and the Camopy, states that the country is a magnificent one, and the climate not bad. The party, having exhausted their provisions, lived out in the open air with the Indians, and led the same life with them. M. Coudreau me so popular with the Rucuyennes that he induced the pamen- chi of the tribe and four of his men to accompany him to Cayenne, where their arrival caused a sensation, and where the Governor made them very weicome. - Coudreau has discovered the existence in undoubted French territory of sixteen new tribes of Indians, forming a group of 20,- ersons. These Indians are sedentary, and have attained a certain degree of civilization.

The population of the Caucasus, which in 1858 was only 4,526,- 000, had in 1880 risen to 5,870,000, the immigration of Cossacks and Russian peasants more than counterbalancing the emigration, while all districts have a regular excess of births over deaths. The Russian element is now in excess of any other, consisting of 1,410,- 000, while the Georgians are but 1,150,000 in number, and the Les- ghiens and mountaineers have diminished since 1858 from 1,400,- 000 to 1,050,000. Lukoma, the principal island in Lake Nyassa, though only four and a half miles long and two and a half wide, contains 2,500 inhabitants. Ula, or witchcraft, of the kind described with much graphic force by Mr. Rider Haggard in one of his earlier works, prevails and is a great curse in the island. Herr Aug. Fitzau (Deutsche Geographische Blatter) gives an account of the West African seaboard between Morocco and the Senegal. Though Arabic is the prevalent language, he believes that the old Hamitic or Berber is still the chief ethnic element. The writer describes in detail the coast between Agadir and St. Louis. Count Teleki has ascended Mt. Kenia to a height of 15,000 feet, and believes its elevation to be greater than that of Kilima-njaro. Corrections made by Dr. H. Heyer himself in the barometrical observations taken during his ascent of Kilima-njaro prove that he did not reach within 820 feet of the summit of the mountain.

Geslogy and Paleontology. 829 The part of Professor Zittel’s valuable “ Handbuch der Palæon- tologie” (III. Band, 2. Lief.) describing the Teleost fishes, has recently appeared. The correlation between the morphology and systematic relations of existing and extinct fishes has been obscured and sometimes contradicted by the adoption of the very misleading and unscientific classification of Giinther. The anachronistic idea that there is near relationship between Plectognath and Ganoid, fishes is consequently likewise still adhered to.! This idea has been so thoroughly exploded by several writers and its fundamental error is so obvious to any one who considers the evidence and compares the structural characteristics of the various types, that surprise must be felt that so intelligent a paleontologist as Professor Zittel clings to it. There can be little, if any, doubt to any competent observer who compares the skeletons and other parts of Scleroderm fishes with the Teuthidids and Siganids that the views of Dareste, Cope and others are correct, that the Scleroderms have originated from the same stock as the ‘feuthidids, and that consequently they are removed further than most fishes, and further even than the related Teuthidoidea, from the Ganoids. The genus Protobalistum is adopted by Professor Zittel with the expanded limits recently assigned to it by Baron de Zigno. To those who adopt Dr. Giinther’s views of the classificatory value of characters, the demonstration of the erroneous association of the forms embra formes, A. cotto-scombriformes, and A. blenniiformes. Now, just such differences as have been used to separate those groups are foun true Scleroderm.

RIACANTHIDA.—Scleroderms with the spinous dorsal very short and composed of a stout anterior spine and several approxi- mated weak ones behind it, the soft dorsal oblong, and with ven- trals represented by stout spines, and with or without weak axillar erable intervals, the soft dorsal short, and with ventrals atrophied L rays. ooi Scleroderms with the spinous dorsal very short, being represented (1) by a stout spine with which a weaker posterior spine interlocks in erection (and often a third spine exists), or (2) by only a single slender spine; the soft dorsal- long or oblong, and the ventrals wanting. : These characters are supplemented by important osteological ones for the last two at least. ` : The family Triacanthide was represented in the eocene seas of Europe by the genera Acanthoplewrus (Ag.) and Protacanthodes (Gill).

Erster Nachtrag zu der Eocenen Fauna der Eger- ingen ; von L. Rütimeyer; Zurich, 1888. Abhandl d. Schwiez. Palæon- tol. Gesselsch. Bd, XV. 832 General Notes. This important memoir is divided into two portions as indicated in the above title. I refer to the second part first in order, by record- ing the discoveries it announces. Prof. Rütimeyer has made the highly interesting discovery of a species of Phenacodus at Eger- kingen, which he names P. europæus. He also refers species from the same locality to the genera Protogonia, (?) Mioclænus, and ©) Pelycodus, and to the new genus Meniscodon. Unfortunately al of these species are known from the teeth only, so that the refer- ences are not yet final. He also gives descriptions of new specimens of Cenopithecus lemuroides Riitim. and Proviverra typica Ritim. In the first part of the memoir, Prof. Riitimeyer discusses the relations of the various members of the Ungulata, with reference to their classification. This consists chiefly of a criticism of the system proposed by Cope, and the results he reaches are expressed as follows: (p. 62). First.—That the categories of Ungulata, based by Cope on the nature of the mutual carpal and tarsal articulations, do not furnish exact definitions for systematic use. Although they furnish instructive series of modifications of the mechanism of motion, they do not offer sharp lines of distinction. Especially can the so-called condylarthrie have a very relative value, and between it and the diplarthrie is there no sharp line. i Second.—The plan of structure which characterizes the superior molars of the Condylarthra consists in a disposition of the tubercles, to which he applies the name trigonodontie, since there are three principal tubercles arranged en triangle, two external and one inter- nal,so that the cross-valley of the crown is closed within. Tt is this type of dentition which is common among lemurs and Insectivora, and which prevails among Carnivora. It is thus probable that trigonodontie is to be regarded as an earlier and more primitive form of molar than those of the zygodont (quadritubercular) piar The selenodont type appears to have arisen from trigonodon ancestors, r t Third.—The trigonodont structure of superior molars as 18 pre’ in the Condylarthra is by no means confined to American Ungulat, ut is found in Europe even to generic details; so that 1t 18 ede = that the foot-structure of the Condylarthra will be also found 0 he ge . ica alone for Fourth.—It is therefore not necessary to look to America aton the first known ancestors of the horse. heen Fifth.— Except the Dinocerata, which, like the Toxodontis, i ped limited range in America, the types of Mammalia have deve z r in such complete parallelism that we are Pae ed to look common and extensive raphical source for them. ‘ Siath—A mong the $ wa a the Cænopithecus of Egerkingen Geology and Paleontology. 833 appears to be as nearly allied to the North American Mesodonta as to the European Adapis. I propose to offer some observations on these propositions, espe- cially to the first and second. The third, and those following, relating as they do to the important discoveries of Prof. Riitimeyer at Egerkingen, constitute valuable additions to the sciences of paleontology and mammalian phylogeny. e first proposition, that the characters of the carpus and tarsus on which I have relied for discrimination of the orders of Ungulata are insufficient for that purpose, is probably so far true, asa similar asser tion made with regard to all structural characters whatever would be. With the discovery of new forms, and the completion of phylo- genetic lines, the sharp demarcations we now employ as definitions will vanish. But I claim with regard to the case of the Condy- larthra, that such discoveries have not been yet made, and that Prof. Riitimeyer’s views on this point have been reached by reason of several misconceptions on his part. The supposition that the tarsus of Phenacodus (p. 14) resembles in any degree that of the rhinoceros and tapir, isan unaccountable error. Also (1. c.) the supposition that the carpus of those animals does not represent the diplarthrous type is an equally extraordinary misconception. So is (p. 15) the opinion that such small contact of the astragalus with the cuboid bone as exists in Phenacodus and Hyrax is diplarthrism comparable to that of Hyracotherium venticolum. ut supposing Prof. Riitimeyer’s view that the carpus of Phena- codus is proboscidian, and the tarsus rhinocerotic, to be correct, an priae distinct from Proboscidia and Perissodactyla would be indi- cated, The fact is that Prof. Riitimeyer, probably from want of speci- mens of Condylarthra, has not fully grasped the meaning of the taxeopod, and especially the Condylarthrous type of carpus and tarsus, That type is the unguiculate and carnivorous, accom- panying hoof-shaped ungues, and as yet no transitions to the usual ungulate type have been found within the Ungulata, except in the carpus of the Anthropomorpha (and the result is not typically ungulate). The Condylarthrous carpus and tarsus are also lemu- rime, and are well distinguished from other ungulate types. The structure of the astragalus of Dissacus among the Unguiculates Shows us what the transition will be like when it is found.' „The second proposition ascribes what Prof. Riitimeyer calls trigonodontie as a definitive and general character of the Condy- larthra. I must here record an objection to the introduction of the word trigonodont. It is proposed to replace the term tritubercular > the Ungulata, so that the latter phrase shall apply only to the Unguiculata. But there is absolutely no difference between ' Transactions Amer.

(3) The South African region, which consists of a of crystalline mountains of enormous extent, covered with innu- merable layers of horizontal sandstone, the age of which lies between that of the Carboniferous and that of the Jura.

The upper part consists of chalk with flints, the lower of bitumi- nous shales and lime, and the group corresponds to the Senonian. The middle group corresponds to the upper Turonian, and contains numerous Rudista, Cephalopoda, and Nerinea, but no Trigonias or ereas; it consists of dazzling white thick limestones wi alternating beds of gray clays, but contains no flints. The lowest group has many Trigonias, Cythereas, and Nerineas, but e Cephalopoda and Rudista ; it consists of sandstones, clays, an arenaceous limestones, and is identified with the lower Tam The Syrian cretaceous is distinguished from that of Europe by f absence of Belemnites and Inocerami.

Messrs. Herrick, Clarke and Deming have a short arti- cle on some American norites and gabbros. Three rocks are described. The first is from Marshall Co., N. C., and is called olivine-norite. Its feldspathic constituent is labradorite, and its pyroxene is regarded as bronzite. The second—a porphyritic dio- nite, contains garnet and apatite. It is a facies of the norite. The Duluth gabbros are finally taken up and briefly described. In one Phase of this rock the authors think they have found feldspar crys- tals, with a central core of labradorite, surrounded by a zone of ortho- clase. Very little new is stated in regard to these rocks, except the view that the orthoclase-gabbros may be derived by the action of solutions (emanating from acid rocks) upon olivine-gabbro. The paper contains the statements of many important views, which, however, will not generally be accepted by petrographers unless substantiated by many more facts than the authors have been able to discover.—An instructive paper on some English tachylites is that by Mr. Cole in the Quarterly Journal of the Geological Society.* In it he describes a glassy basalt which exhibits all the stages in e transition from a glassy to the completely spherulitic forms so familiar among acid lavas. The spherulites are sometimes com- posed of an intergrowth of gray and brown fibres, which show the seas tk Dr S. Bayley, Colby University, Waterville, Maine. ?

The kersantites are panidiomorphie aggregates of plagioclase and augite, together with hornblende, mica, quartz, apatite and a few rare minerals. The panidiomorphic structure passes into the holocrystalline porphyritie toward the edges of the dykes. The minettes of the Odenwald fall into two groups, the minettes proper, and the vogesites or minettes poor in mica. The latter embrace both augitic and horn- blendic varieties. The minettes sometimes contain augite and some- times biotite as their principal ingredient. The granite porphyries s no peculiarity of structure or composition to which attention need be called.—The article on the Archzan Geology of Missouri, to a preliminary notice of which attention was directed in these pages a short time ago, has lately made its appearance.” In addi- tion to the interesting observations already noted, it may be remarked that Mr. Haworth finds the nature of the plagioclase in the porphyrites from this region to be in no way connected with the presence or absence of quartz in the rocks. A more basic feldspar is sometimes found in a porphyrite containing free quartz, than 1m one in which no quartz is visible. The ground mass of a certain class of the porphyries resembles in structure the appearance known as peecilitic.

CasLENTERATA.—The third of the reports composing Vol. XXIII. of the Challenger series is by Professor G. J. Allman, and forms the second part of his memoir of the Hydroida. Only three genera of Gymnoblastic hydroids: Stylactis, Eudendrium, and Monocaulos are represented in the Challenger collections. M. impe- rator is a most remarkable hydroid, having a stem seven feet long though but half an inch thick, and a stretch from tip to tip of tentacles of nine inches, so that all other hydroids sink into insig- nificance as regards size when compared with it. It was obtained at the depth of four miles beneath the surface. The Calyptoblastea were well represented in the collection. Idia, Lamoureux, prov on thorough examination to be constructed on a quite unique type, a new genus, Perisiphonia, represented by two species, was discovered. In this genus the axial tube which bears the hydro- thecæ is surrounded by numerous tubes set with tubular sarcothece, and the hydrothecz projects through interstices in these axial tubes. The curious genus Synthecium is enriched with two new species, hecocladium with one. so traced, may be presumed to have been budded off from fixe trophosomes, to compose a separate group, but leaves them to 8n planoblasts, and the planoblasts are almost always Anthomedn&ls i.e. have the generative elements developed in the walls of w (6) Rhabdophora or Graptolites. Verwes.—Vol. XXIII. of the Challenger series has a sbort report upon the Entozoa of the collection, by Dr. O. von Lin Zoology. 841 Only sixteen species are described, ten of which are Nematodes and six Cestodes. The species obtained were chiefly from the alimentary tract of birds, and include four new forms of Ascaris, three of Filaria, one of Prothelmius, four of Tenia, and two o Tetrabothrium. The appendix mentions a large larval Echi- norhynchus found in the abdomen of a Euphausia, two Distoma, and a Gordius found in a crab, so that the other groups of Helminths are not entirely absent from the collection. Motiusca.—The report upon the Heteropoda of the Challenger collection, by E. A. Smith, although short, contains a most complete synonymic list of all known forms of the group. It is the fifth report in Vol. XXIII. The first two memoirs of Vol. XXIII. of the Challenger Reports are by Dr. Paul Pelseneer, and treat of the Pteropoda Thecosomata, the Gymnosomata having been previously dealt with in Vol. XIX. The Thecosomata have a less highly organized alimentary canal than the Gymnosomata, and content themselves with humbler prey, feeding chiefly on Radiolaria, Foraminifera, Infusoria, and even on some of the lower Algw. Specimens of the group were taken alive at seventy different stations, but no undescribed species were found. All the generic titles that have en given may be reduced: to eight, viz. : Limacina, Peraclis, Clio, Cuvierina, Cavolinia, Cymbulia, Cymbuliopsis, gen. nov. and Gleba. The third part of the report treats of the anatomy of the Pteropoda generally. He considers the group, not as a class, ut as a recent and specialized variation from the Gastropod type. He places them among the Pectinibranchiate Oplsthobranchs, and traces the Thecosomata to the Bulloidea, and the Gymnosomata to the Aplysioidea. | _Crustacra.—Vol. XXIV. of the Challenger Reports is occu- pied with the report of C. Spence Bate, F.R.S., on the Crustacea Macrura. Though styled one volume, it is in wo goodly tomes, the one containing 1030 pages of text, the other 157 litho- graphic plates. Not only are generic and specific diagnoses given with minuteness, but all that is known of the developmental stages (in which direction there is still much work to be _done) is reproduced. Bate follows Dana in placing the Penseidea in a sepa- rate division, which he names Dendrobranc iata, and he considers the izopoda or Stomapoda as forming an aberrant branch of the robranchiata, more nearly allied to the degraded forms of the Penæidea than to those of any other group. He asserts that, with the exception of the pereiopoda, the several genera do not possess a single character that is not held in common with some genus of the poner divides the Macrura into the two principal * 842 General Notes. divisions of Trichobranchiata and Phyllobranchiata, with the Dendrobranchiata (Penæidea and Sergestide), intercalated. Each of these divisions is divided into two sections, the Normalia and the Aberrantia. The family Galethewide belongs among the Trichobranchiata Aberrantia, while the rest of the old group Anomoura form the Aberrantia of the Phyllobranchiate section. These groups will form the subject of a report by Professor John R. Henderson. Recent works upon lacustrine faunas have shown that copepods, and especially those of the genus Diaptomus, are bot numerous in species and more widely distributed than is generally supposed. Most of the ordinary types have been confounded under the name of Diaptomus castor, so that until now it has not been possible to speak with any approach to certainty of the geographical distribution of any species. M.M. de Guerne and Richard have now, thanks to the numerous documents they have studied on the subject, given a map of the distribution of Diaptomus, and proved that it may be regarded as a cosmopolitan genus.

Entomology. 843 modesty, and, placing ourselves in the attitude of the first two classes of his probable readers, namely the beginners and the amateurs or dilettante entomologists, we find that we have little of which to complain. The first class of readers, however, whom he hopes to reach, the farmer, the fruit-grower, and the gardener, the book will hardly satisfy as a hand-book. No one, however, can sig a book on this subject for farmers unless he is a farmer him- self. While our first impression was that Dr. Packard had made a mistake in adopting in this elementary work the division of the class into sixfeen orders, our maturer opinion coincides with his own judgment. Brauer’s classification, or some slight modification of it, is bound to be generally adopted. The sooner this is brought about the better, and in no way could a ready adoption be more speedily achieved than by teaching the system to younger entomo- logists, and to beginners in the study. Dr. Packard’s substitution of Plectoptera and Mecaptera for Ephemeride and Panorpate is, of course, done in the interest of uniformity, but we regret his appa- rent slip in the. etymology of his word Mecaptera. This leads us naturally to criticise the glossary, in that for less than half of the words defined is the derivation given. The same incompleteness 18 seen in the acknowledgments of illustrations. Credit for many 18 given, but many others are unacknowledged, leaving the errone- ous Impression that all the latter are original with the book. _ e are somewhat disappointed with the chapter on collecting, esl and rearing. Although most of the published notes ve been brought together, the chapter is too much a clipped one, and many hy ea points unpublished are omitted. For ex- ample, Prof. Riley’s description of his breeding-cage, published no less than fifteen years ago, is reproduced with its accompanying figure, while no word is said of the later improvements which P rof. Riley and others are using, and with which the author was familiar. Similarly, in the matter of inflating larvæ, no mention 18 made of the tin ovens generally used, or of the method recently described of inflating several larvee simultaneously. The short family characterizations given in small type will be Useful in many instances, but it seems to us a mistake, and a certain discouragement to the student, to insert such definitions as those given on page 126, under the Diptera, viz. :— Family Asteidee—Front bristle above. F amily Phytomyzidæ.—F'ront bristly. amily Agròmyzidæ.—F'ront with strong bristles. , It also seems to us that in a work of this character strict uni- formity in sub-family terminations should have been followed, Whether previously adopted by other authors or not. But we have found enough fault. We anticipate that the book 844 General Notes. will do a great deal of good. Many teachers, we know, will heave a sigh of relief upon seeing it, and we have no doubt but that its sales will be gratifying both to the author and to the clear-sighted publishers. AN INTRODUCTION TO EnromoLtogy.—By the time this number of the NATURALIST reaches its readers, the first half of an elementary text-book of Entomology, prepared by the editor of this department, will have been published.! This part includes the grammar of the science, and half of the systematic part. It con- tains many original illustrations, drawn and engraved by Mrs. Comstock. The following extract from the preface of this work will indicate the author’s plan of treatment of the subject: “This work has been prepared to meet the demand for a text- book which shall enable students to acquire a thorough knowledge of the elementary principles of Entomology, and to classify insects by means of analytical keys similar to those used in Botany. 4 means of the keys the student can readily determine to what family any insect of which he has a specimen belongs. In many cases tables of genera are also given, and the more common or conspicu- ous species in each family have been described. ; “ Although much pains has been taken to render easy the classi- fication of specimens, an effort has been made to give the mere - determination of the names of insects a very subordinate place. The groups of insects have been fully characterized, so that their relative affinities may be learned, and much space has been given to accounts of the habits and transformations of the forms described. As the needs of agricultural students have been kept constantly in view, those species that are of economic importance have been described as fully as practicable, and particular attention has been given to descriptions of the methods of destroying those that are noxious, or of preventing their ravages. Siegen “The pronunciation of the technical terms has been indicated by marking the accented vowel, and at the same time indicating its length when the term is pronounced as an English word.” Synopsis or Norra AmeERIcAN Drerera.—All North American students of Entomology will welcome the work just published by Dr. Williston?

Of course I cannot tell what goes on inside the shell those four or five days after gastrulation and before the larvæ develops tentacles, as the egg is so very opague. I should have said also that at first the eggs are brown, in a few days they show green pigment spots, and these increase until the free larva 1s quite green. “Tn two or three weeks I shall probably have an abundance of material for sectioning and then I want to take in hand the case of the brown Clypeaster, common about here.

The meetings were held in the Central High School, which, though some distance from the hotels, had good street-car communications. The building was admirably suited to the needs of the Association. The rooms were ample both in number and size, while the auditorium, large enough for all general meetings, could be darkened for afternoon lectures with lantern views. The citizens of Cleveland took great interest in the meetings and the local committee made every arrangement possible for the comfort and convenience of visitors. The ladies in charge of entertainments, receptions, etc., devoted themselves to these duties during the entire week and wer eminently successful in everything they undertook. Lunch was provided daily in the basement of the building. Thurs- day afternoon was devoted to receptions given by the citizens at their homes, and some of the magnificent and luxurious residences on Euclid Avenue were thrown open and the members of the Association hospitably received. SECTION 4.—ANTHROPOLOGY. Dr. C. C. Abbott, of Trenton, N. J., was president of this section, with Dr. Frank Baker, of Washington, D. C., secretary. The meetings were well attended and much interest was shown in the proceedings. The section was kept busy with the reading of the thirty-two papers and their consequent discussion, closing only late im the afternoon of the last day. The session of nesday, August 15th, opening day, was devoted to the presidential address, “ Trenton, N. J., by himself; at Little Falls, Minnesota, by Miss Franc E.

It is published in Science for August 17, Thursday, August 16th.—“Certain prehistoric ornaments found in Mississippi,” by Prof. R. B. Fulton, of the University of the Mississippi. He presented about thirty prehistoric beads from Lincoln county, Mississippi. The material was jasper, reddish-brown, mottled witha lighter shade and very hard. Their forms were cylindrical, and also of the shape of deer and birds. They were all, or nearly all, polished and drilled. Prof. Fulton said he had never seen any similar beads except those in the Smithsonian exhibit now open at the Centennial Exposition at Cincinnati. Mr. Wilson said he had prepared that display and had chosen those from the many in the National Museum to show a series descriptive of the method and work of the drilling of these hard substances by the prehistoric man. a learned address on the “ Development of the Civilization of Northwest America.” He raised a query as to the possibility of establishing a connection between Asiatic and American tribes, an noted many indications of relationship, and said the Indian tribes of the northwest coast of America far excel their neighbors in arts and industries. The tribes of the northwest coast belonged to man linguistic stocks. In British Columbia alone were eight distinct tongues. He spoke of the striking similarity of physique between certain tribes of the northwest coast with certain Asiatic tribes. The customs and legends of these tribes were much alike, but in their myths the speaker found the greatest coincidence. His paper, ough replete with facts, was but little more than the announce- ment of his theory, and he closed as follows: “ But before drawing further conclusions we must analyze the civilization of northwest America in order that we may know what we have to compare. Only after this is done can a study of the numerous striking analo- gles be successful in demonstrating the Asiatic origin of these northwest tribes,” is speaker used the term nation as synonymous with people, and civilization as synonymous with culture, to which Major Powell ook exception, 5 The Rev.

Brinton read a paper on “The Alleged Mongolian Affinities of the American Race,” in which he demonstrated that no such affinities existed. His conclusion was the opposite of that of Dr. Boas. An abstract is as follows: Many recent writers assert that the American or Red race presents various traits which bring it into close relationship with the Mon- golian. These alleged resemblances may be classed as either of language, of culture, or of physical appearance. In language the Es- kimo has been said to resemble Ural-Altaic tongues of northern Asia; and the Otomi of Mexico has been asserted to be monosyllabic and isolating like the Chinese. Both these statements are proved erro- neous by recent researches. The American languages differ entirely from any of the Mongolian group. In culture there are various similarities but not more, and not other, than can be pointed out between any two groups of early civilizations, and no one of them is evidence of intercourse. The physical similarities relied upon begin with the color of the skin. Butno American tribe shows the peculiar hue of the Mongol. The hair, though straight in both races, differs in color and to some extent in shape of cross section. The oblique or “Chinese” eye is by no means usual in the American race, scarcely more so than among the whites, and is, moreover, of much less importance than has been maintained. The shape of the skull is markedly different. The Mongolian head is round, that of the Eskimo is notably long, and of other tribes mixed. The nasal index of the American Indian alleged Mongolian affinities of the American race; and this is of but slight importance. : The discussion on this paper was most animated, although it Prof. E. S. Morse, of Salem, Mass., supported the speaker. aoe Horatio Hale, of Toronto, made some observations, as did rof. Mason. Major Powell dilated upon the importance of amp rather than to divide and extend them.

Major Powell answered by declaring his theory of language as a racial test had no application to man earlier than we had knowledge of his language. Dr. Brinton sought to close the discussion by saying that differ- ent races might employ the same language, and that according to his theory, Major Powell could prove, what we know from history and from our senses to be an absurdity, to wit: that because they spoke the same language, the white and the black man now occu- pying the United States belonged to the same race. Major Powell had the final word to say that his opponents had constructed a man of straw that they might enjoy the pleasure of thrashing him. His own position was, that in the beginning all men sprang from the same stock, or if not, they at least found themselves in the same condition ; that there were then no distinct or separate races of men, and that the divisions and subdivisions of race, blood, language, culture or physique had been accomplis little by little, and they had thus finally developed into the different races with their different languages and cultures. But that they still all shaded off into each other and ran together; and, whether counted sideways through the collateral branches in the present day, or counted backwards, each through his own ancestors, it was Impossible to find an exact dividing line between races. all the world was now, as it ever had been, akin, of one race and one blood; and that the subdivisions into races was but arbitrary ; the work of man and not of God. is discussion was the most impetuous and interesting of any in the section. The speakers were able, ardent, fluent, and at times, Major Powell especially, arose to eloquence. r. Hilborne T. Cresson was down for two papers, but he was absent and they were read by abstract. They related to his dis- shown but the implements themselves were not present. Friday, August 17th.—Colonel Garrick Mallery, of the Bureau of Ethnology, Washington, D. C., read a pa entitled “ Recent Discovered Algonkin Pictographs.” Colonel Mallery has been engaged for ten years in the investigation of the sign language of the North American Indian, and is the highest authority on the subject. Colonel Mallery has just returned from a month’s visit among the Micmacs of Nova 852 General Notes. Scotia and around the Bay of Fundy. He had discovered many new pictographs, tracings of which he had taken and presented to the audience. The lecture-room was decorated with these and other specimens in a manner highly interesting. Colonel Mallery told of the investigations and discoveries made by himself and Dr. J. Hoffman, and of their comparisons of the real objects with the descriptions made by Schoolcraft in his voluminous publications issued in 1853, and showed that he (S.) had fairly represented the substance, but sometimes with exaggeration. The principal part of Colonel Mallery’s paper was devoted to a description of the signs and symbols which were on the charts, and to a translation of their messages, Remarks were made by several persons commendatory of Colonel Mallery’s labors. Prof. Mason said: “ We have before us to-day a record of the beginning of a written language. We are standing in the presence of the birth of literature.” And he asked a vote of thanks to Colonel Mallery. Prof. J. E. Todd, of Tabor, Iowa, presented the next paper, entitled “Some Ancient Diggings in Nebraska,” which he illus- trated by a sketch upon the blackboard. These were at Newawka on the Weeping Water creek. ‘They were supposed to be pits dug for the extraction of flint. ‘hey bore some resemblance to the quarry at Flint Ridge, Ohio. f 1 Dr. D. G. Brinton presented “ Early Man in Spain.” He deait first with the chipped flints discovered by Ribera at Otta, ree” were believed to come from the miocene. He said the implements ‘i the neolithic period in Spain have a striking similarity in size an form with those common to the United States. : The Basques are the most ancient known inhabitants of Spam and Portugal. They are believed to have lived there at the _ of the formation of the shell-heaps, which seem older here than 1 Denmark. The Basque language has many peculiarities of o ical American Indian tongue, such as the Algonkin. F Brinton exhibited a map on which the six hundred fathom nig the Atlantic ocean was indicated. An upheaval of the land to er altitude would join the continent of Europe with that of No r America by way of England, Scotland, the Faroë Islands, Io Labrador, and the New England coast. Many things seem oe confirm this theory, which is an opinion held by many geologis The existence of this land-bridge across the Atlantic ocean once established, many ethnologie problems relating to the American Indian would be at once solved. $ Mr. Wilson complimented Dr. Brinton upon his paper and con tinued in the same line. Speaking of the endurance of language _ he said the Basque language was still spoken in France and Spam, and there were many persons now living there in the retired ru Archeology und Anthropology. 853 districts who could speak no other. The aged couple who occupied the house at the entrance of the cavern of Laugerie Basse, excavated by M. Massanet, speak only the Basque language, and any one visiting there must take with him an interpreter who speaks French and Basque. ; On the other hand, the language of the Normans, who came as invaders and settled permanently in that province in the north of rance which bears their name, had entirely died out. It never established itself as a separate language, but joining itself to the French made a dialect, a bastard language, which was neither the one nor the other. The Gallic language brought from Wales or Cornwall into Brittany had survived side by side with the French and continued as a separate language in spite of all efforts of the government to root it out. It was now a law of France that none of these ancient languages, at once foreign and indigenous to France, shall be taught in the public schools. Mr. Wilson described the dolmens, menhirs, and other monu- ments of Spain and France and told something of the efforts made to rescue and preserve them. Mrs. Anita Newcomb McGee, wife of Prof. McGee, of Washing- ` ton, D. C., read the paper of the afternoon, entitled “ American Communities.” This lady had one of the largest audiences of the entire meeting. She was listened to with close attention and received many congratulations. She described in detail with the necessary statistics, the seven principal communistic societies which had been established during the past century in the United States. Her arguments were fairly made and her deductions correct. She did not undervalue a benefit, nor overstate an objection, yet she said she was forced to the conclusion that communism could not permanently rival independent competition. She closed with three fundamental objections to, or causes for failure of communities. - A community does not admit that wide differentiation of labor and variety of occupation which is found outside, and is considered a sign of progress, a _ + A community is an institution intermediate between the indi- vidual and the State, and is antagonistic to that other more natural intermediate institution—the family. This has been felt by com- family, i.e., making the two one, but it so pronounced a return to conditions long abandoned in the course of evolution, that later or monogamie instincts (now normal) refuse to be suppressed, an finally cause the failure of this attempted solution.

The essential object and aim of Communist and Socialist alike, is equally to support and reward the worthy and unworthy, the practical effect of which is to suppress all stimulus to labor, and to reduce all men as far as possible to a dead level of mediocrity. That form of social organization, however, which tends to produce the ablest men and stimulate them to highest efforts must, other things equal, make the greatest progress in social evolution. Com- munism is satisfied with mediocrity, and here is its weakness. - On the other hand its strength lies in its unity of interests—that is, in its element of co-operation. Saturday was devoted to an excursion given by the local com- mittee to members of the Association. The steamer “ City of Cleveland ” left her dock at 8 a.m. well filled with passengers. er first stop was at Kelly Island, where, under the guidance of Prof. Foote and Mr. Severance, the visitors were conducted to the great glacial groovings in the solid rock which had been exposed to view for the purpose of this visit. The steamer then continued to Put-in-Bay. Everything possible was done by the committee * make it a day of pleasure. The day was superb and the lake peer as glass. Concerts were given on board, and amusements, scientilic and dexterous, were the order in the smoking-room. The steamer returned at sundown. A Monday, August 20th.—Mr. A.

He mentioned their aptness in mechanical arts and their strict idea of property. They were highly superstitious and did many things to secure good fortune. A whole tribe would get baptized by the missionary in order to change their luck, and when their luck did not change the missionary had to. Their numbers were diminishing, but this was due principally to changes in diet and clothing, for in that climate the canned beef and cotton over- alls of the white proved but poor substitutes for seal-fat on the inside and sealskin without. Dr. D. G. Brinton, of Media, Penna., described some “ Traits of Primitive Speech.” His abstract was as follows: nguage was not born in a day. Primitive utterance was of single or double consonants. These consonantal sounds were sixty- three innumber. The labials expressed the idea of time and space, the dentals the termination of force, the nasals motion in repetition, the gutterals motion in curves, the “h” ideas of command. The Cree language, to quote from the same authority, resembles the Tinne no more closely than does the French the Chinese. Never- theless, the same peculiarity of materially significant phonetic elements is discovered. I find but little, yet some, evidence in the different groups of American tongues in favor of the theory which maintains that there is some fixed relation between sound and sense in the radicals of languages. “N?” expresses the notion of the €7°, or myselfness in many languages. “ K ” is associated with the idea of otherness. In many American languages the phonetic elements are vague and fluctuating. In referring to the Klamath language Dr. Behrend writes: “The same person pronounces the same word differently and when his attention is called to it he will insist that it is the same.” Some of the consonantal sounds are not true elementary sounds, but in primitive languages had to have Some other consonant associated with them. Phonetic elements were often inadequate to express the idea. In the Indian languages, emphasis, action, and modification of the vocal expressions seem to 856 General Notes. primitive speech presents a very curious phenomenon. In Tinne the same word may express good or bad, high or low. In Cree the union of opposite significations reappear in the ultimate rudiments of the language and numerous series of opposite ideas are develop- ments from the same original sounds. The gradual development of grammar is strikingly illustrated in these languages. Subject, verb, direct object and remote object were all expressed in one word. Primitive words expressed being in relation, and hence partake of the nature of verbs. Primitive man did not connect his sentences. They followed one another disjointedly. Relative pronoun and conjunction are absent in American languages. Few American tongues have adjectives. The question has arisen did primitive man model his sounds after what he heard or what he saw? The former opinion has been most popular. His earliest sounds seem to have been expressive of motion and rest, energy and its absence, space and direction, color, form, and the like Tuesday, August 21st—Horatio Hale, Esq., read a paper on “ An International Language,” for scientific and other purposes. In this he dissected the Volapiik and showed its many errors. He advocated a language founded upon a more scientific basis. His paper is published in The Critic, N. Y., of August 25. r. Wilson doubted the success of the experiment and expressed his belief that no new language could be impressed upon the people y any vote or decree however authoritative. He cited the persis- tency of the Basque and Gallic languages in France and the many dialects extending over all Europe; and this in spite of all efforts to uproot or consolidate them. He thought a common language might be established between the people of different countries by the different governments uniting in the choice of a language (one of the living ones), to be taught in the schools of the country. We Americans could adduce many arguments why English should be chosen as the common language. But suppose the governments | should be unable to agree upon it and German should be chosen. Then in all English-speaking countries there would be taught 8 the public schools English and German; in France, French m German ; in Italy, Italian and German; in Spain, Spanish an German, and soon. Thus every one would be able to speak his own language and a common language which every other perso? of whatever nationality would also be able to speak. _ d Prof. MacFarlane elaborated with approval Mr. Hale’s meth i and commented upon the defects of Volapük. The discussion was continued by Prof. Mason and Dr. Brinton. To be continued. Microscopy. 857 MICROSCOPY. Tue Eees or Ampurera.—I have found hypochlorite of sodium an excellent solvent for the gelatinous envelope of the amphibian egg. I obtained a ten per cent. solution, and diluted it with five or six times its volume of water. The eggs are first hardened by heating, or by immersion in some preservative fluid ; then placed in the Labarraque solution until the gelatinous envelopes are so far dissolved that the eggs may be easily shaken free. They are then washed and preserved in alcohol. This method works perfectly with the eggs of Necturus, and has given equally good results with the eggs of the frog. The time required for dissolving the envelope in the case of Necturus is about five minutes. Care should of course be taken not to leave the eggs exposed to the solvent longer than is necessary in order to destroy the envelope. EXPERIMENTS wrra Currin Sotvents By T. H. Moraan2— The first experiments were made upon the eggs of the common cockroach, and the selection turned out to be a most for- tunate one. A great many eggs are laid at one time, the whole number being surrounded by a stiff chitinous coat, forming the so-called raft The solvents used were the hypochlorites of sodium and potassium, recommended by Dr. Looss in 1885 The most successful experiments on the cockroach’s eggs were as follows: „1. The rafts were placed, in a fresh condition, in a weak solution of eau de Labarraque (commercial fluid diluted with five or six times its volume of water), and left until the chitinous envelope e soft and transparent. The time varies; if slightly warmed the time is less, for the warm solution perhaps thirty minutes to one hour; but one must go more by the appearance of the chitin than by any definite time. If the embryos are far advanced they may now be removed from the envelope one by one ; if still young, they had better be hardened and cut altogether. In both cases the eggs or embryos were next washed for a fow minutes in water, and then transferred for an hour to picro-sulphuric acid, then as usual they are passed through the grades of alcohol, 70 per cent., 80 per cent., 95 per cent. 1 Edited by C. O. Whitman, Director of the Lake Laboratory, Mil- waukee. Vo Studies from the Biological Laboratory, Johns Hopkins University, Ol. iv., No. 4, p. 217, 1888. 858 General Notes. 2. To specimens which have been already hardened and preserved the solvent may also be applied; but in all cases where fresh mate- rial is easily obtainable, it should immediately have its chitin soft- ened and then afterwards be preserved. Here the method is some- what shorter, since the substance has been previously hardened. From alcohol—weak solution—they are put into the Labarraque and softened as above, then passed through water and the alcohols, ete. In most cases in which an animal. egg or embryo is encased in chitin, the best results have been obtained by staining the sections after they have been cut and fixed to the slide. If the specimen is small, staining in toto—after having the chitin softened, or if before this has taken place, after having made an entrance through the chitin with a point of a needle—is equally good. The greatest difficulty, and practically the only one which one meets with, is that the Labarraque solution not only attacks the chitin itself, but after a time the soft tissues of the animal—apparently the connect- ive tissue. Where the chitin surrounds the object completely, as in the case with the roach’s raft, one can remove the object from the solution as soon as the chitin is softened, and before the under- lying parts have been attacked. In cases like this the solvent is at its best Very often, however, the soft tissues of the animal are ex in places between the chitin covering. This is well illustrated by the joints of insects’ legs, etc., and very frequently these expo! places are attacked before the chitin is completely softened, thus causing the joints, if much handled, to fall apart. By judiciously diluting the solution and taking the parts to be softened from it before the joints are attacked, one will find its application practicable even here. The greatest difficulty of all is when the chitin is internal, com- pletely surrounded by soft tissue. So far as I have made any experiments here, I find that one gets better results with very dilute solutions—diluted from eight to ten times, or even more. It m admitted that in this last case the application of the solvent is more doubtful, and of not nearly so much service as 10 the first and second supp cases. ‘a Strong solutions, then, had better be used only when the chitin completely surrounds the soft animal parts, and dilute solutions must be used in all cases where these latter substances are expose The solution not only softens the chitin, but removes all pig! either in the chitin or in the tissue beneath, and this is at ames advantageous. THe Use or CELLOIDIN IN MAKING DEMONSTRATION-PREPA~ Microscopy. 859 Preparation.—1. Alcohol supplies the best means of hardening, as it well preserves the color and form. If other reagents are employed, such as zinc chloride, Miiller’s fluid, etc., the prepara- tion must lie in alcohol awhile before further treatment. . The hardened preparation is removed from the alcohol, made dry superficially by careful application of soft linen, and then coated with a thin layer of celloidin, applied with a fine brush. The cel- loidin is dissolved in a mixture of equal parts of strong alcohol and ether, as for imbedding. The furrows are not to be filled with the celloidin solution, but the walls must be carefully and thor- oughly painted. In order to keep them open during the process o hardening, it is well to fill them with cotton or with blotting-paper. ithin five or ten minutes the celloidin dries to a thin, trans- parent, tough membrane, which protects the preparation and gives it greater firmness.

BY JOHN C. BRANNER. FERNANDO DE NORONHA is a small group of islands in the south Atlantic, about 230 miles northeast of Cape St. Roque, and belonging to Brazil. It is only six miles long by about two wide. There is no important settlement upon it, and though it lies near the track of vessels plying between European ports and those lying south of the Cape, it is seldom visited by steamships and rarely by sailing vessels, Very little is known of the natural history of this island. A very brief visit was made to it by Darwin in his famous voyage around the world, but the time he spent upon it—only a few hours —did not enable him to do much towards studying its natural history. In 1878 the Challenge Expedition landed here, but as the island is used for a penal settlement, the officer in charge of the colony would not give the party permission to make explorations. The few notes made by Mr. Darwin, and those of the Challenger party, furnish almost all the trustworthy information thus far pub- lished concerning it. In 1876, when a member of the Imperial Geological Survey of Brazil, I visited Fernando de N oronha, and spent the months of July and August there, during which times the following notes were made upon its fauna: The island is inhabited by a vast number of birds, most of 862 Fauna of the Islands of Fernando de Noronha. them sea-birds which flock and breed about the inaccessible crags and the small islands and rocks off the main island, and being but little disturbed by visitors, they are not timid, and may often be killed with clubs or caught with the hand. One of the most interesting and beautiful birds on the island is the wig-tail, a white bird about the size of a pigeon, having two long flexible, streamer-like tail feathers! These birds nest and roost mostly upon the lofty sides and about the summit of the great peak. At every hour of the day they may be seen hovering about this majestic rock like great white butterflies, or resting upon the little niches on its sides—white specks against the dark background. When seen at any considerable distance from their nests or roosting places they usually fly in pairs, side by side, each following the other’s motions so exactly that one is at first inclined to think by some optical delusion there is but a single bird where two appear. They seldom fly in a straight line, but rise and fall and zigzag like butterflies, Rats and mice exist here in such numbers as, at times, to constitute a very serious pest and drawback to agriculture. It is recorded that during the occupancy of northern Brazil by the Dutch, about 1630, Fernando de Noronha was abandoned “ by reason of the vast numbers of rats which consumed all the fruits of the earth.”? As one walks through the fields or along the paths he constantly hears their rustling on all sides, and sees them darting here and there through the grass. A certain number of the convicts are assigned to the work of rat-killing, and each one is required to kill a specified number of rats every days. The number is incredi- bly large—somewhere in the hundreds—but I made no note of it, and dare not speak from memory. Cats and dogs have been imported in the hope that they might aid in the extermination of the plague, but though they usually kill them eagerly during a few days, they soon become so accustomed to their pa that they cease to pay the least attention to either rats or mice. I made no notes upon the occurrence of rats and mice upo?

If they con- stitute a plague upon the main island, what shall be said of them here? It is simply impossible to realize, without having seen and experienced them, how mice can exist in such numbers. I spent a night on this island, the guest of the three convicts occupying < FERNANDO de NORONHA.

My hammock was suspended in the solitary grass-thatched hut, and at night I tried to sleep there, but with very poor success.

No sooner did I lie down in my hammock than they made their way down the cords and into my bed. During the early part. of the night I amused myself by allowing them to reach the middle of the taut hammock cords, when, by striking the cords a sharp blow, the vibrations would shoot them off into space. This ceased at length to be amusement, and when, late in the night, I occasion- ally fell asleep, it was only to be awakened in a few moments by the mice nibbling at my face or hands or feet, or by their falling upon me from the roof. The occurrence of rats upon the main island and of mice only upon Ilha Rapta may possibly be explained by the mice having been imported to the smaller from the larger island. The geology of this group of islands, however, suggests another plausible expla- nation. Fernando de Noronha and the small islands lying about the main one are of igneous rocks, with the exception of some limited exposures of comparatively recent calcareous sandstones formed by the consolidation of sand dunes. These calcareous sand- stones form all of Ilha Raza and Ilha do Meio, the southwest third of Ilha Rapta, and overlie a portion of Sao José and the extreme northeast point of the main island. -It occurs also at the southeast base of Atalaia Grande, and in the Bahia de Sudoest, where it forms Ilha de Chapeo and the shore of the bay in places. In all these localities the sandstone is cut away on its south- eastern side, and an abrupt or overhanging face is exposed to the ocean’s surf, while its upper surface stands at an elevation of from thirty to fifty feet and more above the water. On the landward side of the exposures on Ilha Rapta, Sao José and the main island, these sandstone beds thin away to the west. These facts, and others _which need not be mentioned here, go to show that the south- eastern coast of these islands formerly extended much farther 1n that direction, and that the calcareous sands, of which these rocks are formed, were blown inland from the beach which once existed in that direction. The ocean, however, has gradually encroached upon the island, and especially from the east, until what was formerly one island has been separated into six, namely, Sao José, Sella Ginete, Ilhas do Meio, Rapta, Raza, and the main island. The mice which are so abundant upon both islands now may Fauna of the Islands of Fernando de Noronha. 865 have been cut off from the main island and left upon Ilha Rapta when this separation took place. Whether they would sur- vive upon the other islands, Ilha do Meio, Ilha Raza, ete., would depend entirely upon whether the conditions upon them for survival were favorable or otherwise, and their existence or non- existence at intermediate points would have but little bearing upon the question. It may be asked, in case this theory is correct, why we find no rats upon Ilha Rapta. This is possibly to be attributed to their having been entirely exterminated by the convicts. Ilha Rapta is, in-a sense, one of the institutions of the penal settlement. It has an area of less than a square mile, no wood, though it is said to have been wooded formerly, but little potable water, and, compared with the main island, it is very low. e soil is extremely fertile, and excellent sweet potatoes grow wild over a large part of it, while the waters about its shores swarm with edible fish and enormous sharks. When, at the time of my visit, and prior thereto, a prisoner upon the main island became particularly unmanageable, he was banished to Ilha Rapta, which was regarded as a sort of insanctum insanctorwm, where he was left to his own devices for subsistence. I learned from the commandant that formerly large numbers of convicts were banished to Ilha Rapta at the same time. Now it was generally understood when I was upon Fernando that rats were not uncommonly eaten by the convicts on the main island, and as those sent to Ilha Rapta were left to do as they saw fit, they were often reduced to great straits for food, and it does not seem improbable that they ate rats, if rats ever existed there, Then, too, when efforts were made to raise crops here, the , Tats, had they existed in such numbers as upon the main island, would simply have rendered such crops impossible. The area of the island is so small, and the places in which rats could hide so few, that their extermination would not be an impossible or even a very difficult matter. I trust that the novelty of it will be sufficient apology for a short digression here to describe the method employed by the convicts on Ilha Rapta to catch fish. A hook attached to a line about 150 feet long, baited with a fresh sardine or the white skin of some other fish, is thrown out into the water and quickly drawn ashore. 866 Fauna of the Islands of Fernando de Noronha. The method is thus essentially trolling without a boat or spoon. One end of the line is tied to the fisherman’s body, the line coiled and held in the left hand, while the baited hook, weighted with a bit of lead, is whirled rapidly above the head with the right hand, until the centrifugal force becomes strong enough to carry the line out to its full length when skilfully thrown. It is then allowed to escape, and the lead, carrying the line with it, shoots out over the water and drops. The line is then hauled in as rapidly as possible, and this rapid hauling in generally produces a whirling of the bait at which the fish strike. There is “many a slip,” though, between hooking a fish and landing it; not that they are particularly game, but because the sharks are usually fishing at the same time and place. Not more than half the fishes I saw hooked here were landed entire; sometimes only half a one was hauled in, at others only a head, and sometimes the hook and part of the line were also missing. Standing upon one of the overhanging rocks at the western end of the island I have looked down into the sea when it was comparatively smooth and seen hundreds of enormous sharks in the water, gliding over and about each other in their search for food. Perhaps the most interesting vertebrate found on Fernando is a species of lizard—Mabina punctatas. The cultivation of almost all the tillable land on the island has had the tendency to drive these lizards into the rocky corners and uncultivated places, where they exist in such great numbers as to cause one to wonder how 50 many of them manage to live on so small an island. As they are but little disturbed, and have no natural enemies here, they are not very timid. Walking over the open, rocky places where there 1s no vegetation, one may see the lizards withdrawing down the sides of the rock fragments, apparently with much reluctance, at a dis- tance of from three to six feet ahead of him. If he turn and look behind he will find them rapidly closing up the space yielded him for a passage. While seated upon the bare rocks I have often observed these little animals watching me, apparently with as much curiosity as I watched them, turning their heads from side to side as if in an effort to be wise. If I kept quiet for a few minutes they would creep up to me and finally upon me; if I moved, they Fauna of the Islands of: Fernando de Noronha. 867 ran down the faces of the rocks, and turning, stuck their heads above the edges to watch me. I caught a great many of them! by keeping quiet until they came within easy reach and then snatched them. They bite freely, but their teeth are too short and weak to inflict a severe wound. Upon one occasion when climbing with my photographic apparatus up a steep bluff, where great care and attention had to be given to every step and motion, my movements were not sufficiently rapid and decided to keep the lizards off my person, and as neither of my hands was free, they became offen- sively familiar. Several of them crawled leisurely over me examining my clothing ‘and my person, and one even got up the leg of my trousers, and for nearly an hour crept around and around my waist just below the band of my trousers. I was told by the inhabitants that there was another kind of a lizard on the island which had two tails. I found, however, that the so-called forked-tailed lizard was the same as the above men- tioned one. The tail of this species is long and slender, and is so easily broken that it was quite difficult to catch one without break- ing off a portion of its tail. If the piece broken does not fall off entirely, the break may heal over sufficiently to hold it securely, while the growing out of the new tail gives the lizard a forked or double one. I have seen it stated, I believe in the Challenger reports, that this species has never been found elsewhere in the world than upon Fernando de Noronha, and that the species to which it is most nearly related occurs in Demerara. I saw no snakes upon the island, and the old residents say there are none, save what is known in Brazil as the cobra cega (blind snake) or cobra de duas cabeças (double-headed snake). I found one specimen of this. It is a species of Amphisbeena. Several insects are found, the most abundant of which is a spe- cies of wasp, which does considerable damage to grapes, and by building nests in the cajú trees renders itself very obnoxious. Spiders are also very abundant. A few beetles and butterflies were taken, but the material was turned over to Mr. Herbert H. Smith, and I am unable to say what they are. All kinds of domestic * These specimens, like all the other material collected upon this island, was deposited in the Museu Nacional in Rio de Janeiro. As far as I know, none of it has ever been worked up. Fauna of the Islands of Fernando de Noronha. animals have been introduced upon the island, but they do not enter into the biologic question to which I would call attention. It does not seem improbable that the original flora and fauna of Fernando were introduced here at the same time and from the same source. I regret that I made no notes of value upon the flora of the island, but I may call attention to this peculiarity of it: its large trees produce light wood, that is, wood that will float in the water. The flora of the Brazilian mainland is noticeable for the predominance of very heavy timber, most of which, even when well seasoned, is of too high specific gravity to float in salt water. One of the large trees of Fernando is the Ficus noronhae, a species first described from this island. Another is the burra, a species of laurel yielding a poisonous juice. I believe I have seen the laurel in the highlands of the province of Minas Geraes, but I am not quite positive about the identity. The question naturally arises: Where did the animals inhabit- ing this island come from originally, and how did they get to Fernando de Noronha? The first answer which suggests itself is that they have been imported by man’s agency since the place was discovered. Very fortunately we have valuable documentary evidence upon this sub- ject. The following is a translation of the oldest document mm existence referring to the island of Fernando de Noronha :— “.... In view of the services which Fernam de Noronha, cavalier of our house, has rendered, and which we shall expect of him hereafter, and desiring to show him grace and mercy, we are pleased to bestow upon him henceforth for all the days of his life, and on his eldest legitimate son surviving at the time of his death, our island of Sam Joham which he has just. lately discovered fifty leagues over the sea from our land of the holy cross.” * This is a portion of the patent issued by the King of Portugal, January 24th, 1504, at “ Lixboa,” and recorded in the royal archives of Portugal? Now “Sam Joham,” or in modern Portugues?, 1 The original name given Brazil by Cabral was Vera Cruz. generally known, however, as the Zerra da Santa Cruz until about the middle of the sixteenth century when the name Brazil was generally adopted. 2 Real Archivo, Bk. 37, Chane. D. Joao III., Fol. 152. (Dairio de Pero Lopes, p. 71-2.) Fauna of the Islands of Fernando de Noronha. 869 Sao Joao, was the original name of the island, and after this patent it appears to have been known by the name of its owner, Fernam, or Fernando, de Noronha. From this document, and others relating to the fleet in which Fernando de Noronha sailed, it is believed that the island was discovered on the 24th of June (St. John’s Day), 1503, and that it was called the island of “Sam Joham,” or St. John, in accordance with the usage of the times, which was to name places after the saints upon whose days the discoveries were made. Americus Vespucius claims to have visited this island on his fourth voyage, six weeks after its discovery by Fernando de Noronha. I am aware that historians question whether this voyage was ever really made by Americus Vespucius, but judging from the description given by him it must be confessed that if that navigator did not himself see this island, he obtained his informa- tion concerning it from some one who did visit it, and for our purposes this serves the same end. If his informant was a member of Fernando de Norouha’s party, it is only the more valuable in the present connection. . The description given by Americus Vespucius is brief, but it is the earliest one published, and there- fore the most important for the present discussion. According to this account he touched here August 10th, 1503, and he writes :— ger ear es Which island we found inhabited, and it contained plenty of trees, and so many birds, both marine and land, that they were without number, and they were so tame that they allowed themselves to be caught with the hand; and we caught so many that we loaded a boat with them; and we saw no other animals except very big rats and lizards with two tails, and some snakes,” As the introduction of birds, whether marine or land, upon an island 230 miles from a large continent, cannot be regarded as difficult or impossible, the presence of birds upon Fernando may be passed by as of no particular importance. The interest in this _ ease centres upon the “big rats and lizards with two tails and some snakes” mentioned by Americus Vespucius. As the island was discovered but six weeks prior to the reported visit of this k Stanislau Canovai’s Viaggi d’Amerigo Vespucci, Ed. 1817, p. 110, €t seq. 870 Fauna of the Islands of Fernando de Noronha. navigator, it is clearly impossible that these animals, if imported by the discoverer, could have multiplied in so short a time suffi- ciently to have attracted attention. Nothing is said of the mice, and it may therefore be that these are or are not aboriginal inhabit- ants of the island. But the rats are here, and the lizards with two tails, the only ones likely to attract the attention are here, and the Amphisbeena is here, an animal bearing such a resem- blance to a snake that by most people it is called a snake, even to this day. Where did these animals come from? Rats are world-wide in their distribution ; the species of lizard found here has never been found elsewhere ; Amphisbzena is abundant in Brazil, and in Africa, and one genus (Blanus) is found about the Mediterranean. If we suppose that they migrated from the Brazilian mainland, and that the Huprepes does occur, but has not yet been found there, a question as to method arises. Now as the ocean currents do not, i- ge atc on t / Se i l > VA Ii > Witte. 7 4 E at any time of the year, set eastward, northeastward or southeast- ward from the eastern part of the South American continent in the direction of the island of Fernando de Noronha, the chance of such animals being carried from the Brazilian mainland are ex- tremely small. The island receives the currents from the south- western coast of Africa, as is shown in the accompanying cut; indeed the west flowing south equatorial current divides just about here, the current striking the island and flowing either to the northwest or to the southwest along the Brazilian mainland, according to the time of the year and the direction of the trade winds. The wind Fauna of the Islands of Fernando de Noronha. 871 charts usually represent the prevailing winds in this region as coming from the southeast. During the months of June, July, August, and September, they do come from that direction approximately, but during the remainder of the year they are usually from the northeast. The ocean currents shift slightly with these prevailing winds, so that when the winds from the northeast have prevailed for some time, the main body of the south equatorial current seems to be carried further south. Such changes throw upon Fernando at one time the currents from southwest Africa, and at others probably some of the counter-currents from the North Atlantic or from the Gulf of Guinea. Dr. Atfred R. Wallace, with whom the writer has spoken in regard to this question, suggests that these animals may have been introduced upon the floating trunks of trees from Africa. If we admit that such animals could endure so long an ocean voyage, the explanation satisfies the demands of the case as far as we are acquainted with them. The long existence of navigation as a science prior to the dis- covery of America, suggests that rats might have been carried here upon a wrecked vessel. But even admitting that the Amphisbena and the lizard might have come from some part of the Mediterranean, the chances of such animals finding their way upon board vessels are so extremely small that this hypothesis seems to have but little or no value. Tt has been suggested also that the islands of Fernando may have been joined to the Brazilian mainland at one time, and that by the cutting away of the isthmus joining the two, the island was thus left with the fauna found by its discoverers. The form of the Ocean’s bottom between the mainland and the island puts this hypothesis out of question. It was formerly supposed that Fer- nando had once been the northeastern point of Brazil, but the deep- Sea soundings by the Challenger expedition show that this is not true, and that Fernando is separated from the mainland by a trough More than 12,000 feet deep. In the light of these facts the ques- tion remains: where did these animals come from, and how did they get here? 1! During my stay upon this island, in the monthsof July and August, the wind varied but little from due east, being at times from the E. N. E., and at others from the E. S.

Journ. Set. May 31, 1886, we divide the animal kingdom into thre¢ compre- hensive divisions: (1) Prorozoa, unicellular animals, which propagate by means of asexual (autotemnic) fission and by spores, and build up colonies, but always remain typically unicellular. (2) Mesozoa, multicellular colonies, but composed of only one layer of cells, so closely connected, that they may be called a primitive tissue, and having more or less spherical forms.* They propagate by means of ova, spermatozoa, and by autotemnic fission,* and have an aula or common cavity, but no specialized digestive cavity oF archenteron.

Holoblastic ova may be regarded as the more primitive or generalized forms to which 1 Abstract of a paper read at’ the meeting of the Bost. Soc. Nat. Hist., Nov. 16, 1887. Vol. xxiii. * Proc. Bost.

The stages of holoblastic ova may be in a general way classified as follows, to accord with that given above for the Animal Kingdom :— (1) The ovum or Monoplast (Lankester) ; (2) the first stage of segmentation, which normally results in the production of two cells in the same place originated by vertical fission, the Monoplacula ; (3) the second stage of segmentation in which two layers arise, the Diploplacula. The*first two stages alone seem to have parallel or representative adult forms among Protozoa. The differentiation into esoteric, primitive ectoblast, and enteric, primitive endoblast cells takes place in the Diploplacula, and the morphological equiva- lent of this stage of the ovum, having an upper layer of differentiated feeding cells, has not yet been found among the adults of the Protozoa ; though, if this is correct, such a discovery may be reason- ably anticipated. We have proposed to classify these stages under the name of Protembryo. (4) The Blastula is in aspect and general characteristics the morphological equivalent of the adults of the genera Volvox and Eudorina, the types of the Mesozoa or Blastrea, The latter are animals in which growth remained permanently arrested at the single-layered, spherical stage in the evolution of tissue-building orms. We have proposed to classify these stages under the name of Mesembryo, (5) The Gastrula can be compared, as has been done by Heckel, with the lower Porifera (Ascones), but these have three layers like the lowest Hydrozoa, in which a three-layered gastrula-like stage has been permanent] y preserved.!

They do not possess, as a rule, the essen- tial diagnostic characters of the larger divisions to which they belong, and we propose to call them Neoembryos. Examples: the Cinctoplanula is not a sponge, the Planula of the Coelenterata is not a Ccelenterate, nor the Pluteus an Echinoderm, nor the Trochosphere a Mollusc, nor the Pilidium a Nemertean worm, nor the earliest planula-like ciliated stages of Amphioxus a Vertebrate. Neoem- bryos are, as pointed out by Semper,! Lankester ? and Balfour,’ so similar, that they may be considered as indicating a common ancestor for the entire Animal Kingdom. (7) The latest of the more specialized planula-like stages are either directly transformed into, or else give rise to other forms in which the characters of the larger subdivisions or types of the Animal Kingdom begin to appear, at least so far as essential characters are concerned. Examples: the Ascula and Ampullinula are true sponges, the Actinula isa Hydrozoon, the Gulinula is an Actinozoon, the Veliger is a Molluse, the internal worm-like form arising in Pilidium is a true Nemertean, the formation of the notochord in Amphioxus makes the planula-like embryo into a vertebrate animal. They have the essential characters of the larger subdivisions, though it is equally true, that embryos in this stage of development are very remote, in some cases, from the adults of any normal forms. We do not, therefore, misinterpret these relations by naming the embryo in these last stages the Typembryo. This term can applied to the Nauplius of Crustacea, and the Echinula* of Echino- dermata, as well as to those above noted. 1 Semper, Stammsver, Wirbel. und Wirbello., Arbeit. Zoolog.

Sci., V. 29, 1880, p. 410, shows that there is a stage of the embryo common to all orders of living Values of the Stages of Growth and Decline. 875 Typembryos serve to connect the earlier stages of the Neoem- bryos with the true larval stages which succeeded the former. Balfour and other embryologists have used the term “larva” for free neoembryos and typembryos. This term should be confined to the designation of stages of growth which are immediately con- tinuous with later stages and parallel, or referable in their origin to the adults of allied, existing, or fossil forms, which are not so remote as those from which the embryonic stages were derived. The application of such principles to the study of the younger stages of fossil Cephalopoda is productive of what seem to be satisfactory results, The protoconch of Owen is, according to this nomenclature, the shell of the univalve veliger of the Cephalous Mollusca, and a true typembryo which, though eminently charac- teristic of that group, has no exact morphological equivalent among adults of normal forms whether recent or fossil: The protoconch in fossil Nautiloidea is represented by a withered- looking lump sticking to the apex of the conch in a very few excep- tionally perfect specimens. The very general absence of this lump and the presence of a scar left by its removal on the apex of the conch, and the wrinkled, shrunken aspect of the lump when pre- served, indicate the protoconch to have had a horny texture in this order. This typembryo shell must have existed among Nautiloids with an almost unchanged aspect from the earliest Cambrian (Lower Silurian) horizon until the present day, and its adult equivalent probably existed before its appearance in Cephalopoda or in the equally ancient and allied group of the Pteropoda, which also had similar protoconchs. The true larval, or as they are here named, Silphologic’ stages, began with the formation of what Owen has appropriately called the apex of the conch or true shell. Among Nautiloids this was a short living chamber occupied by the body of the animal, but having no Echinodermata. This stage, however, was not named in the address above quoted, which was intended as preliminary to an illustrated essay on the same subject, and Mr. Agassiz has supplied that omission in the following note, which I quote from a letter to me. “I intended some- time when revising my ‘ Address on Pal tological and E yological, Development,’ to call the earliest tag derm embryos ; Echinula’ for convenience in making comparisons.—A. Agassiz.’ Zion, a grub. of g wW 876 Values of the Stages of Growth and Decline. siphon or septum. It was completed by the deposition of the apical plate, which sealed up the aperture of the protoconch thus closing the opening and cutting off communication between the two interiors. This stage can therefore be named the asiphonula or siphonless larva. The apex of this conch was rounded, being built out in con- centric circles from the contracted aperture of the protoconch, probably before this was plugged up by the deposition of the apical plate. The asiphonula was not a Cephalopod, since it had no central siphon, nor even a septum. It may have resembled more or less closely the adults of some of the ancient Pteropoda. Von Jhering has thought, that the characteristics of the early stages of Ammonoids justified a comparison between them and forms of Pteropoda having similar protoconchs. This was our own position also, but we now see, that the asiphonula was not necessarily a wholly pteropod-like animal. It may have retained many of the veliger’s characteristics, and may have more or less resembled a generalized type to which a Scaphopod is the nearest living approxi- mation. Prof. W. K. Brooks’ opinion, that the Scaphopods are such a generalized type and that the veliger has characters which can be compared with those of the adult of Dentalium ought at any rate to be considered here. | . = It is not at all improbable, that the Pteropoda may never have served as radicals for the Nautiloids or Ammonoids, but the latter may have sprung directly from the ancient Scaphopoda. ; The cicatrix naturally suggests comparison with the posterior opening in the shell of Dentalium, but if our view is the true one, and it represents the aperture of a protoconch, no such comparison can be made. The development of the conch in Dentalium is, ac cording to Lacaze Duthier’s researches, directly continuous with that of the protoconch, and the posterior opening is the result of the peculiar mode of growth of a primitive plate of shell which is never closed up. The shell, in other words, is a periconch growing around the body in the veliger and finally coalescing to form a tube open at both ends. : : The second larval stage in Nautiloidea was composed of a living chamber closed apically and completed by a single septum, which had a cecal prolongation reaching across the first air chamber and 1 Proc. Bost. Soc. Nat. Hist., Aff.

It is proposed to call this stage the Czecosiphonula, since it is undoubtedly the primitive stage of that organ. The cecosiphonula may indicate the former exist- ence of an ancestral form having a central axis composed of similar closed funnels or cecal pouches.! The third Silphologic stage in Nautiloids was completed by a septum (the second in the apical part of the shell) having an open funnel extending apically and joined to a loose textured siphonal wall which reached down into and lined the cecum, thus forming a secondary closed tube. In accordance with the structure this has been named the Macrosiphonula. The protoconch was present in Ammonoids and also in Belem- noids, but in both of these orders it was calcareous. The tendency to form a calcareous shell, which first appeared in the apex of the conch of the asiphonula in Nautiloids, became by concentration of development inherited earlier in the Ammonoids and Belemnoids in the veliger stage, thus transforming what would otherwise have been a horny shell into a calcareous one. The protoconch was, however, not otherwise changed in external aspect and retained the usual egg-like shape of the univalve veligers of the Cephalophora. As in the protoconchs of other similar veligers of Gasteropoda, ete., and as a result of calcification, the protoconch became fused with the apex of the conch more intimately than in Nautiloids. In other words the asiphonula, ‘after transmitting a portion of its characteristics to the typembryos of the Ammonoids and Belem- noids, disappeared, having been replaced by the Caxcosiphonula. The septum of the cxcosiphonula was consequently also inherited earlier, and became a functional substitute of the apical plate serv- ing to close the aperture of the protoconch, and its cecum extended into the upper part of the otherwise empty protoconch, in place of occupying the first air chamber as in Nautilvids. This is a remark- able example of the law of concentration, but by no means excep- tional. The fourth larval stage of the Nautiloids was completed by the building of the third septum. This septum had a long funnel and attached porous wall, but the wall formed a true siphonal tube opening apically into the next section, the macrosiphon. This * See also similar remarks by Whitfield, Bull. Amer. Mus. New York, No.1, and Em ryol. Ceph. by the author, Bull. Mus. Comp. Zool., V. 8, No. 5, p. 100 878 Values of the Stages of Growth and Decline. was the beginning of the small siphon and can be appropriately termed the Microsiphonula. The microsiphonula was the typical stage of nearly all the known genera of Nautiloids, beginning with the Orthoceratites of the Cambrian and found at the present time in Nautilus, and also in all Ammonoids and Belemnoids without exception. Fortunately the genesis of both macrosiphonula and microsi- phonula can be traced in the adult forms and silphologic stages of well-known fossils. The Crytocerina had a siphon which was macrosiphonulate probably even in the adult stage, since it increases in diameter throughout life. Piloceras had a huge siphon hardly at all contracted in the adults of some species, but considerably lessened in diameter during the same stage in others. Endoceras had also a large siphon always more or less contracted in the silphologic or later stages. The uncontracted macrosiphonula occupied in this genus a number of air chambers varying according to the species, from a few to six or more. This was evidently due to the earlier inheritance or concentration of the tendency to decrease the diameter of the siphon first manifested in the adults of Piloceras. Sannionites was a genus in which the siphon was smaller than in Endoceras, and probably, though this is not yet ascertained, inherited the tendency to microsiphonulation at the ` first septum at an earlier age than in Endoceras. None of these forms, however, attained a true microsiphon, since even Sanni- onites had the siphon filled by endocones and in the centre an endosiphon.. These organs entirely disappeared in true microsi- phonulate forms and, in fact, could have existed only within a large macrosiphon. j Nevertheless this tendency to decrease the size of the siphon resulted in the formation of a definite constriction. This constric- tion was inherited at earlier and earlier stages after its origin m the siphon of Piloceras, until it became constant perhaps in Sanni- onites and certainly in the Orthoceratide. The constriction marked the line between the larger and smaller siphon in the macrosipho- nulate forms, and, in becoming constant through concentration, it became invariably fixed behind the first septum between n cæcosiphonula and the smaller siphon. This smaller siphon, though still a macrosiphon in structure, as explained above, even use Values of the Stages of Growth and Decline. 879 Sannionites, was undoubtedly transitional to the true microsiphons of the Orthoceratide. The cæcosiphonula was in all Orthoceratites, which are other- wise similar to Endoceras, confined by concentration of development to the first air chamber, and a true microsiphonula appeared at an early stage as an open narrow tube. This was similar to the siphon of the vast majority of all succeeding forms of both Nautiloids and Ammonoids. According to the classification here advocated, the stages preceding the microsiphonula, viz.: the asiphonula, cecosiphonula and macrosiphonula, became silphologic stages in all the groups of Cephalopoda descending from the radical - Endoceratide. | Microsiphonulation became silphologic in the Orthoceratide, and the smooth shell which they evolved was subsequently inherited among Nautiloids, Ammonoids and Belem- noids during the younger stages in all the species of these orders. Other forms, with depressed and involved whorls, were introduced in the main stock of radicals among Goniatitinse, and were modi- fications of the smooth cylinder of the simpler Orthoceratide with its microsiphon. These in turn became the proximal radicals of derivative groups. Thus the Anarcestes'! among Goniatitine became the radicals of the Ammonoidea, and the smooth silphologie Stages of all Ammonoids after the expiration of the Devonian were like the adults of these lowest forms of Goniatitine. This later acquired silphologic stage has therefore been styled the Goniatitinula, It has also been found, that in tracing the descent of forms with- in smaller groups, sub-orders, families, and genera, it is practicable, as in the case of the family of Endoceratide, to prove that characteristics usually appear first in adult stages and are then inherited at earlier and earlier stages in successive species of the Same stock, whether they occur on the same horizon, or in different horizons. The adolescent or Nealogic? stages are of as great import- ance for tracing the genealogy of small groups as are the silpholo- gic characters in larger groups. Thus one can speak in definite terms of the relations of the nealogic stages, and their meaning and importance in tracing the genealogy of families and genera, * Gen. Ceph. Proc. Bost. Soc, Nat. Hist., V. 22, 1880, p. 305. ? Neadyc, youthfulness. 880 Values of the Stages of Growth and Decline. without danger of confusing them with the characters of any of the silphologic stages. After the silphologic and nealogic stages have been disposed of there still remains the adult period, which is equally important in genealogical investigations, since it enables the observer to study the origin of many characters, which afterwards become silphologic and nealogic in descendent forms. It is not uncommonly assumed, that adaptive characters appear- ing in embryos and larve are apt to be transient and have but little effect on the subsequent history of the early stage in the same group; also, that such characters have appeared just as readily in the larvee as in adults. Up to the present time this has not been - found to be true among fossil Cephalopoda, and there exist, so far as known to the author, but few characteristics probably originating in the early stages. The constant recurrence of hereditary charac- teristics in silphologic and nealogic stages which originated in adults, like those given above for the Endoceratide, makes the probability of the assumption, that the asiphonula and veliger represent the adult stages of lost types, so highly probable, that the burden of proof must rest upon the opponents of this argument. Each case of the origin of characters in embryo and larve should in other words be regarded with distrust until proven. The appearance of the incomplete modes of segmentation in existing Sepioidea may possibly be a case of origination in embryo. There are no adult forms known to the author, which store up food in their tissues in such a manner that they can be used to explain the origin of the specialized food yolk. Nevertheless special inquiry might have very unexpected results. The case above given of the calcareous nature of the protoconch, and all the other characters of the stage in the Ammonoids and Belemnoids, seemed to have originated in embryo until it was found that a distinct silphologi¢ stage, the asiphonula, existed in Nautiloids, and that this indicated the former existence of an asiphonulate ancestor having a calcareous shell. Some of the characters of the goniatitinula, such as the deep ventral saddle of the first septum in the angustisellate young, te described by Branco, doubtless originated in the younger stages. These are, however, correlative with the anarcestian form of this Values of the Stages of Growth and Deeline. 881 stage and with a general tendency to closer involution, which acted the same way in every series of forms, whether we select series of adults or of embryos for comparison. The use of a distinct term for the adult period becomes necessary not only on this account, and to separate its relations from those of preceding periods, but also because of the constant recurrence and importance of representative forms. The term Ephebology * has accordingly been adopted for the designation of the relations of the adult stages, and under this term can be classified also the represen- tation of similar forms in different groups or morphological equiva- lents. These are often so exact that it becomes very difficult to Separate them. They have been and will continue to be the most difficult and misleading obstacles to the student of genealogy and classification. In former essays we have described and defined the senile trans- formations and their correlations with the degraded forms of the Same groups. The nature of these relations is, as has been explained, quite distinct from those of the progressive and adult stages, but the correlations are nevertheless equally important for the classifi- cation and tracing of genealogies during the declining period of a group, and in the case of degraded and aberrant forms. We have, therefore, for some years past designated these relations by the term Geratology.? This nomenclature is similar to that adopted by Heckel, but is, when properly considered, also supplementary and based upon morphological rather than physiological grounds. This eminent author regarded the ontogeny of an individual to be divisible into three periods : first, the stages of Anaplasis or those of progressive evolution ; second, the stages of fulfilled growth and development, Metaplasis ; third, those of decline, Cataplasis. He also appreciated and gave full weight to the general physiological correlations which are traceable between the history of a group and the life of an individual, and, in accordance with these ideas, designated the pro- gressive periods of expansion in the phylogenetic history of a group as the Epacme, the period of greatest expansion in number and variety of species and forms as the Acme, and the period of decline in numbers of species, ete., as the Paracme. ! “Egnfog, the age of puberty. * Tépas, old age, 882 Values of the Stages of Growth and Decline. Heckel used also the term Anaplastology for the physiological relations of the stages of progressive growth and those of the Epacme of groups, Metaplastology for those of the adult and the Acme of groups, and Cataplastology for those of the senile stages and the Paracme of group. These terms seem to cover the same ground, as those we have employed, but they were in reality chosen for the purpose of classifying physiological relations. Thus the anaplastic relations of the Embryologic, Silphologic and Nealogic stages to the phenomena occurring in the Epacme of groups, and the metaplastic relations of the Ephebolic stages to the phenomena occurring at the Acme of groups, and the cataplastic relations of the Geratologic stages to the phenomena occurring during the Paracme of groups, are the functional relations of one class of morphological modifi- cations to those of another class and do not properly include the morphological phenomena themselves or their morphological correlations. The necessity for a double set of terms may possibly not be at first admitted by many zoologists on account of their too exclusive devo- tion to the morphological side of their studies, but a very slight — experience in trying to express the serial correlations of morpholo- gical and physiological phenomena will very soon show them, the convenience of such a nomenclature. Geologists have already arrived at this conclusion with regard to the classification of strata in the earth’s crust and have begun to use two parallel series of terms, one giving the nomenclature of the relations in time, Era, Period, Age, etc., and the other the faunal relations under the headings of Group, System, Stage, and so on. The time has come for recognizing a similar parallelism between structural or statical phenomena of organisms and their dynamical or physiological relations in time, and it is necessary to separate these clearly by different series of terms in order to see not only how they are separable, but also their correlations. Te We have been more or less constantly observing and publishing on the Geratologic stages among fossil Cephalopoda for more than twenty years and have repeatedly described the more or less exact comparisons, which can be made between the different stages of de- cline in the individual and the degraded forms occurring in the oaiae group. 1G. K. Gilbert, Address, Am. Ass. Adv. Sci., 1887. Values of the Stages of Growtn and Decline. 883 There were two stages in the old age period among Ammonoids : the first of these can be designated as the Clinologic! stage. This immediately succeeded the ephebolic period and during its continu- ance the nealogic and ephebolic characteristics underwent retrogres- sion, Ornaments, spines, and sutures degenerated and lost their angularity, the ribs of pile, and often the keel and channels, when the latter were present, became less prominent, and before this stage closed the whorl itself sometimes decreased, showing that degenera- tion in the growth force of the animal had taken place. Similar phenomena can be easily observed in other departments of the animal kingdom, notably in man, whose habits tend to preserve life until he has attained extreme age. During this period there is a steady loss of the differential characters acquired during the stages of progressive growth and there is a tendency to resume the propor- tions and aspect of the earlier nealogic stages. | In man, baldness of the head, loss of teeth and resorption of the alveoli, loss of the calves, rotund stomach, and the return of early mental peculiarities, are phenomena of similar import. The last changes in the ontology of the animal may be termed the Nostologic stage,? and during this stage these tendencies reached their highest expression. Among Ammonoids the ornaments were all lost by resorption, the whorl became almost,as round and smooth as it was in the silphologic stage, and in extreme cases it was separated from the next whorl, leaving a perceptible gap. This almost complete reversion to the aspect of the silphologic Stage can of course only occur in animals which attain an extreme age, The correlations of Clinology are exact, and indicate the changes which may be expected to occur in the same group whenever de- graded or aberrent species can be traced ina more or less continuous Series of graded modifications starting with any given normal form, Many such series have been traced, and these are recognized now by all paleontologists as genetically connected. They began with normal, close coiled, ornamented, shells, the descendants were smaller, showing a tendency to be less involved by growth, to lose their ornaments, and simplify the outlines of the sutures, though * Kiva, to incline downwards. * Néozog, a return. 884 The Poison-Apparatus of the Mosquito. they had coiled young stages similar to those of the normal forms from which they must have originated. The correlations of Nostology can only be artificially separated from those of Clinology, but there existed one class of forms which can be compared only with the nostologic stage. These are the degenerate straight Baculites-like shells, which belong to several distinct genetic series and should often be widely separated on that account. Their resemblances are undoubtedly close, but they are due to degeneration and, therefore, simply homoplastic. Naturalists sooner or later will begin to recognize that degeneration may pro- duce close representation in forms having distinct origins. The Baculities is a smooth, straight, cylindrical though slightly com- pressed shell, which has socompletely reverted that it resembles an Orthoceras, though it isan unquestionable Ammonoid of the Jura and Cretaceous. THE POISON-APPARATUS OF THE MOSQUITO. BY PROFESSOR G. MACLOSKIE, T oral armature or proboscis of the mosquito ( Culex) is described and figured in Dimmock’s Mouth-parts of Some Diptera, and consists of a labrum, two mandibles, two maxille, surrounding a hypopharynx, and all these enclosed in a loose scale-covered sheath, which is the labium. They are nearly three millimetres long, about four times as long as the head; and all except the sheath are smooth, chitinous stylets. The maxille bear maxillary palps, scaly, four-jointed, about as long as the head in Culex, and three times as long in the allied genus Ano- pheles. I have only to add to Dimmock’s description that besides the somewhat coarse serration of the maxilla (about fifteen teeth near the top of each), Minot S. Morgan, of Princeton, has shown very fine serrations on the upper part of the mandibles (about forty-two minute teeth on each). : The hypopharynx is in the axis of all these mouth parts, bemg inserted by a basal enlargement close behind the oral aperture, and The Poison-Apparatus of the Mosquito. 885 flattened so as to form the floor of a sucking tube whose sides and roof are formed by the grooved labrum (or labrum-epipharynx according to Dimmock). This sucking tube extends back in the head, piercing between the upper and lower brain, and enlarged in the posterior part of the head into a large pumping organ, which forces the imbibed fluid backwards into the cesophagus and stomach. In the last century Reaumur thought he could detect a drop of saliva ejected by the proboscis when stinging; he supposed that this is poisonous, and that its special function is to prevent the coagulation, and thus to promote the flow of blood by suction when the insect operates on our skin. We do not believe that he possessed any instrument that could show the poison; but his inference as to the presence of poison and its function is almost certainly correct. It seems to us, however, that the chief food of this insect is not animal blood, but the proteids of plants; and probably the fluid ejected may prevent the coagulation of all pro- teids, and so promote the process of suction. It has been very often suspected that the poison-duct is con- tained in the hypopharynx, which has a thickened axis, like a rod, Supposed by some observers to be tubular. Dimmock made out the tubular character of the corresponding part of some of the larger non-poisonous Diptera, but he was not able to demonstrate its tubular character in Culex. In addition to his observations that go to prove the existence of poison in its bite, I may add my own observation, that even when failing to draw blood its bite will sometimes swell the part, the subcutaneous tissue being irri- tated by poisonous matter. He concludes from the careful exam- ination of all the parts that no other channel can conduct this poison ; and adds, “This, together with the position occupied by the salivary duct in other Diptera, leads me to believe, without as yet being able to give anatomical proof of it, that the hypo- pharynx of Culex contains a duct that pours out its’ poisonous saliva” ; and he further states that he was unable to determine the actual presence of the glands. A year ago I succeeded in making out the duct and also the glands, and published a preliminary note; I was unable, however, at that time, to correct errors or to complete the work. This 886 The Poison-Apparatus of the Mosquito. past summer, however, gave me an opportunity of revising the subject, so that I have acquired some facility in finding and dis- secting the parts. I find that it is even easy to see the venomo- salivary duct from the outside, shining through the skin at the base of the head and neck in the undissected specimen. Also, thanks to the supervision of Professor Libbey and the manipula- tion of Dumas Watkins, of Princeton Histological Laboratory, I have been supplied with a set of excellent sections, which show the relations of the parts. One of these sections is here engraved in part (Fig. 1), exhibiting the insertion of the duct into the base ‘of the hypopharynx, and its course below the nerve. I have also teased out and stained some of the glands, which have enabled me to show their structure and relations, as in Fig. 2. The secret was first discovered by an observation of fine drop- lets of a yellow, oily-looking fluid escaping from the apex of the hypopharynx (Fig. 1). I was then able to trace the course of this fluid down through the axis of the hypopharynx, its being divided in parts into droplets, and so indicating the tubular struc- ture of this organ. On examining the base of the hypopharynx I found it to be enlarged like the mouth of a trumpet, and provided with a sac-like reservoir, into which the end of a fine duct was inserted. Working backwards I saw the duct to be of the usual character of salivary ducts in the Diptera, but much finer than usual, . ` EE ates oi microms ing less tha 4 E: atar ipty. -in the house-fly.!' It is not readily identified by a low microscopl¢ power, and this may explain why it has not been previously detected. It has the usual chitinous lining, surrounded by the nucleated hype” dermis which secretes it, transversely'striated as in trachese (Fig. Hi but it is distinguished from the tracheæ by the comparative smal 7 ness and constancy of its diameter, and by the absence of ramifica- tions.

Each set consists of three glands, two of which are of the usual aspect of salivary glands, resembling in structure, but not proportionately as long as, the single salivary gland on each side in the prothorax of the house-fly. The third gland, that occupying the centre of each set, is different, being evenly granular, and staining more deeply than the others; its function being without doubt the secretion of the poison. Each gland is about one-third of a millimetre long, and one twenty-fifth of a millimetre broad ; the three are arranged like the leaves of a trefoil; and each is traversed throughout by a fine ductule, the three ductules uniting at the base to form a common duct, which is like a pedicel of the trefoil and is one of the branches of the bifur- cated venomo-salivary duct. The ductules of the lateral glands of each set receive a minute branchlet near the base. Thus there are six glands, three on each side, two of them poisonous and four EXPLANATION OF FIGURES.—Fig. 1.

The two efferent ducts, one from each set of glands, carry forward and commingle the venomo-salivary products in the main duct: and the stream is then carried by the main duct to the reservoir at the base of the hypo- pharynx. There is no other exit for the contained fluid. I see muscles apparently inserted on the frame-work of this reservoir (Fig. 1, m); but Dimmock seems to think that the hypopharynx is not furnished with muscles. However this may be, the pressure exerted on it by the surrounding parts, when the mosquito inserts its piercing apparatus into the flesh or through the epidermis of a plant, is sufficient to propel the poison through the tubular axis of the hypopharynx into the wound. The reservoir must be furnished with a valve to prevent the reflux of the secretion. The distal ori- fice of the hypopharynx is not exactly terminal, but sub-apical, as is usually the case with fangs; the very tip is somewhat flattened and sharp, so as to enter easily into and to enlarge the wound made by the adjoining organs. Careful observations are needed as to the behavior of mosquitoes on plants; as to the condition of the hypopharynx and the glands in the males and in the larve. The observations here noted were ` made on the adult females of Culex (C. teniorhynchus Desv.), and on a species of the allied genus Anopheles, which is characterized by its long maxillary palps.

KINGSLEY. { SA BEBER, crusty, cancer, canker, are terms which at once recall to most persons various disagreeable features and more serious ailments of human beings; to the naturalist they at once suggest the crabs and the group Crustacea to which these animals belong. There must be some reason why the crabs have thus acquired this bad name which goes even farther than indicated above. They are by common consent regarded as ill-tempered, ready to pinch Something about Crabs. upon the slightest provocation, and anything but straightforward in their actions. When a man begins “to crawfish” (the verb is sanctioned by usage, if not by lexicographers) he does not inspire respect. Yet who cannot recall some surly member of the commu- nity who is universally regarded as crusty and crabbed, but who, on more intimate acquaintance, reveals another character, quite at variance with the estimation in which he is popularly held? So it is with the crabs. Their crustiness is all external, and if one be willing to run the risk of an occasional nip, he will find that these much maligned creatures have many attractive aspects, and like the rest of nature they amply repay the time spent in their study. Tntellectually the Crustacea are supposed to rank pretty low in the scale, but it is an open question whether this inferiority be an actual one, or whether it results from deficient observation. We can take the ants into our studies and watch their every motion, but the crabs are not so easily domesticated; captivity does not agree well with most of them, and even with those which can be kept, the surroundings are so strange that we have an element entering the psychological equation the value of which it is not easy to ascertain. Of all the Crustacea with which I have had personal acquaintance, none are more interesting, either in captivity or on their native beach, than the fiddler crabs, those apparently misshapen forms which throng every suitable stretch of sand along our shores from Cape Cod to the Gulf of Mexico. A pic- ture is well in its way to illustrate the shape and general appearance of an animal, but no picture can present to us the animal in action, nor represent its varying moods and phases. The fiddler, with its quadrate body, its eyes seated on the tips of the slender erectile pedicels, those eight slender, sharp-pointed legs, and that enormous pincer, can readily be drawn, but the changing aspects of the body are beyond the artist’s power. When you draw near the beach where these crabs are abundant, no matter how cautiously you have approached, there is a hurried rush of myriads of these crabs, each scuttling away as fast as four pairs of legs will carry it, to a place of safety. At such a time the appropriateness of the common name is seen. In every direction are the fiddlers, each plying its small claw across the enormous fellow in the most amusing manner. No matter how often seen, 890 Something about Crabs. one cannot help thinking of the musician—usually bald-headed— away down to the left of the orchestra, who so vigorously saws the bass notes from the viol. Let the latter scamper away, viol and all, as rapidly as does the crab, and the simile would be complete. When, however, you seat yourself and allow the cancrine commu- nity to regain its wonted quiet, then you can study these forms to your heart’s desire, and see the various occupations. Some are engaged in gathering food, others in building houses. None are idle, but there seems to be no general supervision, each individual following his own inclinations. The holes in which they live vary somewhat with the species. Those on Cape Cod excavate a simple tube leading to a cavity sometimes a foot or two beneath the sur- face. Further south an allied form appears which arches over the mouth of its burrow with an oven-like roof, beneath the shade of which the proprietor sits and watches for any approaching danger. These fiddlers are rather remarkable among the crabs in that they live in pairs. Mr. Fiddler is the one who goes about, builds ‘the house, collects the food, and fights the battles and defends the family honor. ' His faithful spouse is but rarely seen above ground, but what her duties are in her cellar home is a problem yet to be solved. You may at once recognize her by the fact that she lacks the fiddle of her other half. Both of her pincers—hands one might almost call them—are of the same size and resemble the smaller hand of the male, and she uses them indiscriminately in feeding the principal use to which they are put. The fiddler crabs are usually said to be vegetarians, and, indeed, the greater proportion of their food consists of alge. They do not, however, confine themselves to this diet, but will eat dead insects or crabs, and, in confinement, they will at times turn can- nibals, and prey upon the weaker individuals of their own species. This may be prevented by feeding them often enough and a suffi- cient amount of vegetable matter. I have had them thrive for months in confinement upon crackers soaked in water, of which, though not their natural food, they appear to be very fond. When thus kept captive they afford very interesting pets, and their actions cause a good many questions. The care is extremely simple. First get your crabs and your jar or box of moist sand, put to Something about Crabs. 891 crabs in with the sand and the vivarium is stocked. All that is necessary to keep it in running condition is to occasionally moisten the sand, and to supply new food before the old is exhausted, Kept in this way fiddlers will readily live in confinement through the warmer months, and possibly through the winter as well, though I never tried to keep them so long. I had only male fiddlers, and these I kept in the ordinary glass fruit jars which were half filled with sand. This furnished them endless employment, for they were constantly digging new burrows and filling up those dug but a few hours before. Why this dissatisfaction I am not able to say; possibly it was a case of “Ccelebs in search of a wife.” A fight between fiddlers is an amusing affair. When one sees his enemy approaching he immediately puts all his forces on a war- footing. The long-stalked eyes are erected so as to watch every motion of his antagonist; the big pincer furnishes not a bad imita- tion of the shield with which the soldiers of ancient times protected themselves, while the tension of every nerve is shown in the dainty way in which the eight walking legs trip over the sand, holding the body as high as possible in the air. At last the two meet. There is a clash of arms, each striving to grasp his antagonist and at the same time to protect himself, but might here takes the place of right, and the victor is he who loses the least number of members. There is no surgeon to bind up the wounds, but the amputation of a limb is not such a serious matter here as with human warriors. The yellowish blood which flows quickly coagulates and forms a covering for the wound, and then nature immediately sets about replacing the missing member. The way this is accomplished is so interesting and so different from anything occurring in the lords of creation that it deserves a moment’s atten- tion, The crabs are covered with a hard and unyielding armor which does not admit of growth. So at intervals they shed their shell, and then form a new and larger one, which in turn will be cast to accommodate still further increase of size. In the fiddler crab the first sign one notices of the approaching molt is a splitting of the integument just where the slender tail (which is kept folded beneath the body) joins to the larger anterior portion. 892 Something about Crabs. Through the opening thus afforded the crab now withdraws him- self, coming forth a soft-shelled, weak, flabby creature. Now he is a pitiable object. The claws, which before could pinch so sharply, are now limp asa rag. His meanest enemy would now find him an easy victim, utterly incapable of the slightest defence. On account of this unprotected condition immediately after molting, all of the Crustacea seek some sheltered spot when about to cast their skin, and hence the operation is not often seen. ‘The process has its differences in the different species; thus the shell of the lobster splits down the middle of the back, while that of the horse- shoe crab splits around the sharp front edge, so as to afford the opening through which the animal is to emerge. There are, however, other processes which precede the splitting of the shell, which need to be mentioned, and which, as they have been most studied in the lobster, will be described as they occur there. First a word as to the nature of the shell. It is what is called a cuticular product. That is, it is not composed of cells like the rest of the body, or like the skin of man, but of a peculiar substance secreted by tle cells lying beneath. Its density in various species differs not only with the thickness of this layer, but as well with the amount of carbonate and phosphate of lime which is deposited in it. It is this outer non-cellular layer which is cast at each molt, while the cells secrete a new shell. If one examines closely any crustacean they will see (more numerous and larger m some places) that all over the body there are small hairs, but these hairs differ from those of man in that they consist of the same cuticle as the rest.of the body, and have an axis cylinder which arises from the cell beneath. It may also be said that these same hairs are organs of sense. One of the first preparations for a molt is the formation of new hairs and a new cuticle beneath the old one, and these new hairs have to lift and tear away the shell from the underlying shell. It is an interesting fact that in certain rep- tiles which “shed their skin,” there are bristles which lift the old integument in the same way. Another feature to be noticed is the way in which the lobster withdraws its big claw, and probably the same is true of the fiddler, though this is mere surmise. He examine a lobster we find that the pincer is much larger than the joints which connect it with the body, and it seems impossible that PLATE XVI. Cast Aye brain-case ag Di were Figs. | and 2.

Skull of Diadectes phaseolinus Cope, from above. Something about Crabs. 893 he large muscl es which close the pincers can pass through the small flattened rings of the intermediate joints. However, a change takes place in these before molting. There is an absorption of the cal- careous matter on the inner surface of these joints, so that they lose their former rigidity and allow the passage of the parts beyond them. In this connection mention may be made of the “ crab- stones ”—small calcareous bodies occurring on either side of the stomach in Crustaceans about to molt. Although no definite knowl- edge exists as to the purpose of these masses of lime, it seems probable that they are stores which are to be drawn upon in harden- ing the new shell. Huxley thinks that this cannot be the case, because these bodies are of inconsiderable size in the crayfish, an argument of but very little weight. But we are wandering afar from our subject—the way in which lost parts are reproduced in the crabs. Until a molt occurs the wounded veteran has to wander about without the limbs lost in battle, thin stumps seared over by the film caused by the coagulated blood. When the molt takes place we see a change. In the place of the lost leg there rapidly expands a new limb, which is like the old one in all respects except size. It is much smaller, but at the next molt it becomes as large as its fellow. A curious feature con- nected with the molting is that the lining of the stomach is cast at the same time with the outer shell. We have explained above the reason why the fiddler crab has received its popular name, but he is in reality a true fiddler. Like many other crabs he has a means of making a noise, and the big claw is his musical instrument. On the inner surface of this member is a row of small rounded tubercles (their position varies with the species), and these can be rubbed against the edge of the shell, producing a note best likened to that caused by rubbing a quill toothpick over a file. There are other crabs concerning which the popular literature is much greater than that relating to the fiddlers. Possibly more has been written about the hermit crabs than about any others, for certainly no one ever visited the shore without noticing these curiosities. They occur in all seas from the tropics to the poles, but wherever found all exhibit that common characteristic which has given them their name. We have all heard of that old Greek 894 Something about Crabs. Diogenes, who made his home in a tub, or, as others will have it, in a cracked amphora, and is it to be wondered that while natural- ists were ransacking all ancient history and mythology for names, that the old philosopher should have to furnish a cognomen for some of these, his prototypes? A hermit crab needs protection for the hinder part of his body, for this is covered with a delicate cuticle and could be easily injured. The desired security is sought by inserting this “tail” in the cast-off shell of some univalve mollusc, the curl of the tail and the rudimentary limbs with which it is provided serving to hold the shell tight, and thus protected the hermit wanders over the bottom or along the beach safe from almost anyenemy. The little hermits have small houses; the large ones have their larger cells into which they can retire for protection, and, who can say, not for meditation and prayer? The house-hunting adventures of the hermits have been so fre- quently described that a repetition is useless. When the body grows too large for the old home a new shell is sought, its dimen- sions are carefully measured by claws and antenne, and, if it be thought suitable, moving takes but an instant of time, and the hermit is in a new and larger home. All hermits, however, are not troubled with this frequent recurrence of moving day, for they have living homes, the growth of which is sufficient to accommodate their usual increase in size. They start in life with a borrowed shell, just as do their more familiar cousins of the shore, but a sea anemone helps them later. This latter animal becomes attached to the shell, feeds upon the crumbs dropped from the hermit’s table, and grows as he grows. Soon the shell is covered, and then the anemone begins to spread and thus builds a tube for the crab. It goes further, for it absorbs the old shell, and with its own body gives all the protection which the crab needs. Thus the strange partnership goes on ; the crab providing food—at least in part—the anemone furnishing the protection. In this respect the latter is far more efficient than the first glance at its soft and skeletonless body would indicate, for it is provided with stinging organs of no mean order, and many a fish is deterred from swallowing crab and all by the nettling it receives from this soft-bodied flower of the sea. A few years ago but a few of these cases of association of hermit crab and sea anemone were known, but more lately the deep-sea : ings have furnished numerous examples. Something about Crabs. 895 This association of forms, which is known as commensalism—a term, a free translation of which would be fellow-boarders—receives numerous exemplifications among the crabs. One form, first described from the Pacific ocean by the late Dr. Stimpson, settles down upon a piece of growing coral, which then proceeds to build a protecting nest about it, leaving only openings for the ingress and egress of the water bringing food and oxygen to the prisoner. Even more remarkable is the case of the shrimp, which so far has only been found enclosed within the glassy network of that beau- tiful sponge, the “ Venus-flower-basket.” So strange was this association that when it was first noticed it was thought that those dextrous fingers of the east, which furnish those wondrous ivory carvings and which fashion those curiosity-exciting mermaids, had placed the shrimps within the sponge, and then had closed the opening so skilfully that the detection was impossible. It would now appear that this is not a counterfeit to be be laid at their doors. Another strange case of commensalism is furnished by some small crabs which are more nearly related to the fiddler with which we started, and of which the little oyster crab is an example. These crabs live inside the valves of oysters, clams and other molluscs, and in olden ‘times quite a pretty myth grew up about them. The delicate Pinna of the Mediterranean (a bivalve mollusc somewhat resembling our familiar salt-water mussel) was eyeless, and in order to escape the jaws of some wandering fish it had to be told when to close its shell. This position of watchman was filled by the little crab which was constantly on the alert, and which in return for its services was protected by the mollusc. This little crab was called Pinnotheres—guardian of the Pinna—and the same name is embodied in the scientific nomenclature of to-day. Relatives of the oyster crab seek other homes. On our Carolina coast is one which lives in the strong tubes built by one of the worms, while in the Pacific are found others which take up their residence in the pos- terior portion of the alimentary tract of certain sea-~cucumbers or holothurians, The fiddler-crabs are largely air-breathers. In fact, so long as they are in a moist location, where they are in no danger of drying up, they do not need to actually enter the water for weeks or months atatime. In this respect, however, they are equalled, if not excelled, 896 Something about Crabs. by several species (some their near relatives) which occur in tropical countries, the warmer portions of America possibly being their metropolis. These land crabs are strange creatures, which, like their marine relatives, are provided with gills, but which, unlike them, stay away from the water for months at a time, and which are drowned by submergence almost as quickly as any terrestrial mammal. There is a considerable diversity in their habits. Some frequent the lowlands near some stream or shore, while others, notably in Jamaica and on the Isthmus of Panama, live in the dense damp forests which clothe the highest mountains. They are not easily caught, for they can run with an agility which almost surpasses belief, while their strong pincers have powers of nipping which are not to be despised. Usually but a few are seen at a time, for during the day they rest in their burrows or in holes in the rocks, venturing forth for food only as evening draws near. Once a year, however, they are compelled to visit the shore to lay their eggs. They then appear in incredible numbers, year after year, on almost the same day. They march along in vast armies, turning to neither side for any obstacle, but devouring everything green in their line of march to the sea. In connection with these terrestrial crabs many interesting physiological experiments are yet to be made. Years ago it was noted that besides the gills, the gill chamber contained a very thick and spongy lining membrane, which was of use in respiration, and several years later Professor Semper made similar observations upon an East Indian species, in which he recognized not only the spongy layer, but also ascertained that it was richly supplied with vessels; in short, that this organ, so far as function was concerned, is a veritable lung, though of course of a far different origin from that of the higher vertebrates. Science-Teaching in the Schools. 897 SCIENCE-TEACHING IN THE SCHOOLS. BY WM. NORTH RICE, [Continued from page 774. ] pe many who concede theoretically the desirableness of the study of natural science in the lower schools, maintain that the practical dificulties in the way of its introduction are insuper- able. It is objected that we have no competent teachers, no ade- quate material facilities, and no time in the already crowded curric- ulum. Science-teaching in the lower schools, it is said, belongs to that far-off millennium ‘“ When the war-drum throbs no longer, and the battle-flags are furled,— when a constitutional amendment has abolished alcoholic fermenta- tion, and made vice forever impossible,—when governments, no longer compelled to support military, naval, and police forces, can spend the bulk of their revenues on education,—when eyery pri- mary school can have a well-equipped laboratory, museum, and observatory,—when every primary school teacher is a Ph.D. of a German university,—and when a reformed orthography has added about three years to school life, by obviating the necessity of spend- ing that time in learning to spell. I believe, however, that the reform is thoroughly practicable. My own official duty, as a mem- ber of a college faculty and of a city school board, has required a careful study of all parts of the educational curriculum in a thor- oughly practical spirit. And I should regard the general discus- sion I have given as of little value, unless I could propose some definite and practicable measures. The most serious difficulty i in the introduction of natural science into the lower schools is undoubtedly the lack of competent teach- ers. That the mass of our teachers are incompetent for any very high quality of science-teaching, is a truth as unquestionable as it is melancholy. That much of their teaching will be merely book- ish,—that much of it will be so blundering that the scholars will have a good deal to unlearn,—is very certain. This difficulty has 898 Science-Teaching in the Schools. been so strongly felt by many scientific men, that they have despaired of any successful science-teaching in the schools till a new generation of teachers can be raised up. “ Better no teaching at all than poor teaching,” is the principle on which they feel them- selves reluctantly compelled to advocate the postponement of a reform whose need none can feel more strongly than they. But I believe the worst teaching we are likely to get is better than none. Very poor teaching of science will at least serve to keep before the mind of the child the idea that there is an external world which is worthy of attention and study. Better that many errors should be learned, than that the child should grow up without thinking of nature at all. No habitude of mind that is likely to be generated by poor teaching can be so bad as the habitude of stolid indiffer- ence which is the natural result of the present system. If we wait for teachers well prepared, before we introduce science-teaching, we shall wait indefinitely. Teachers will prepare themselves after a fashion to teach whatever they are required to teach. No way of making a boy swim has ever been found so effective as putting him into the water. There are books in abundance (and the number is constantly increasing), from which a teacher possessed of a fair degree of men- tal activity can get suggestions which will enable her to doa limited amount of science-teaching soundly and well. Paul Bert’s “ First Steps in Scientific Knowledge” is an admirable guide for teachers of elementary science. Morse’s “First Book of Zoology,” and Winchell’s “Geological Excursions,” are books in which acknowl- edged masters of science have shown how science may be taught to- the young. The series of scientific tracts for teachers now being published under the auspices of the Boston Society of Natural His- tory are good, as judged from both the scientific and the pedagogi¢ standpoint. Worthington Hooker’s books of science for children, though now somewhat behind the times, are still attractive and helpful books. And the teacher who cannot find something to interest the youngest in Johonnot’s series of natural history readers, with their delightful blending of fact and fancy, the science and the poetry of animated nature, is stupid indeed. The teaching of science in the lower schools can be considerably helped by the teachers in the high schools. In most high schools it is practicable to obtain the services of one or more teachers who Science-Teaching in the Schools. 899 have had some genuine scientific training. Arrangements can be made whereby these teachers can now and then give a helpful lec- ture to the teachers of the lower schools, or give to those teachers the best kind of an object lesson by teaching a lesson in science to the children in their schools. The summer schools and seaside laboratories afford the means for teachers whose early opportunities for scientific study were scanty, to gain a sound (though necessarily limited) knowledge of scientific facts and methods. The increasing number and the increasing pat- ronage of such institutions is a hopeful sign. They are destined to be of immense service in improving the quality of science- teaching. The second objection usually urged against the introduction of science-teaching in the lower schools is the lack of material facili- ties. The force of this objection, however, vanishes, when it is considered that no one proposes for the lower schools complete sys- tematic courses in science. Such courses wonld indeed demand extensive laboratories and museums. But for somewhat desultory lessons on judiciously selected topics in science, whose aim is prima- rily to cultivate the powers of observation, and secondarily to afford glimpses of the methods of scientific thought, no extensive mate- rial facilities are needed. Many of the most important principles of physics and chemistry can be well illustrated with no apparatus except what can be extemporized. A class of tolerably active boys can collect enough material for biological study as they go along. Many of the most important conceptions of philosophical biology can be illustrated without any specimens which are not everywhere accessible. A boy who has found the elbow, wrist, knee, and ankle, in a cat, a horse,a bat, and a hen, has learned the idea of homology, though he has never compared the arms of a brachiopod with the lophophore of a bryozoan, and never heard of the gastrea theory. The third objection usually made to scientific study in the schools —the lack of time in the crowded curriculum—hardly deserves an answer. Let the waste of time and mental energy be stopped, which is involved in attempting studies at unnatural times and in unnatural ways, and there will be time enough. Of all economies, the most important is the most neglected—the economy of mental effort. I believe the introduction of science-teaching in the schools will be felt by the pupils as a delightful recreation, rather than as 900 Science- Teaching in the Schools. an additional task; and that the improvement of morale will actu- ally enable the schools to accomplish more in other studies. It remains, then, to outline briefly the work which may be profit- ably attempted. In the primary schools, and the lower grades o the intermediate, or grammar, schools, the main objects must be to keep alive the child’s curiosity in regard to natural objects, to cultivate the power of accurate observation, and to impress the mind with the idea that nature is worth studying. The attempt to teach any systematic body of facts and doctrines, so far as it is made at all, must be strictly subordinated to these more gen- eral objects. Hence it is no matter how desultory the lessons may be, if they tend to keep the mind of the child in loving commu- nion with nature. The pupils should be encouraged to collect and bring to school specimens of all sorts of natural objects. So far as time allows, each specimen should be the subject of a les- son. Judicious questioning should bring out all the facts and phe- nomena which the child has observed or can observe in regard to the specimen. Then the teacher should add something of explanation or information in regard to the object itself or other related objects. And let questions be suggested now and then, which the child and his elders are alike unable to answer. Thus the child will become: early habituated to the complementary truths of the transparency and the unfathomableness of nature. He will learn that he can see into nature a little way for himself, but that beyond his vision stretches a vast unknown. The specimens brought in will be an utterly heterogeneous collection—now a bright-winged butterfly, now a flower, now a plant with insect galls, now a sea-shell brought home from some summer visit to the sea-side, now a lustrous erys- tal, now a smoothly rounded pebble. All the better. Jet the children learn the manifoldness of nature. It will be time enough later for them to survey the fences of systematic definition which man has run through nature’s continuous and illimitable fields. Short excursions in the woods and fields (or in the parks which afford almost the only glimpses of nature to the unfortunate chil- dren who are brought up in the great cities), and visits to muse- ums, zoological gardens, and menageries, will be helpful supple- ments to the work of the school-room. Besides the utterly desultory lessons already considered, a begin- ning may be made in the primary schools in somewhat more sys- Science-Teaching in the Schools. 901 tematic teaching. The objects most interesting to children are liv- ing things—plants and animals. Botany and zoology should accord- ingly be the principal subjects in the science-teaching in the lower grades. The comparison, drawing, and description of various forms of leaves, will furnish delightful occupation and valuable discipline for the youngest children. A little later the more easy and conspic- uous flowers can be studied, and later still the more obscure and difficult flowers. In zoology, attention should be given not to crin- oids and hydroids and infusoria, but to the mammals and birds and reptiles and fishes and insects which the children can see alive. In places immediately on the sea-shore, some of the more conspicuous marine animals may advantageously be included. The most common and familiar mammals, as cats, dogs, horses, rats, should be first studied; and rudimentary ideas of homology and teleology and the principles of classification can be developed in the study of these most familiar objects. From mammals the study may proceed in later years to birds, and then to the less familiar lower classes of vertebrates, and later still to arthropods and mol- luses. Along with the change of subjects, there will naturally be somewhat of a change of method. There will be less of simple observation and description of external characters, more explana- tion of anatomy and physiology, and more discussion of general relations, In several of the States, laws have been passed, requiring in all the schools instruction in physiology and hygiene, with special ref- erence to the effects of stimulants and narcotics. There has been an element of fanatical exaggeration in the philanthropic agitation which has led to such legislation, and some of the books which have been prepared, and some of the teaching which has been done, in obedience to the demand, have not been of great scientific value. I believe, nevertheless, that simple lessons in physiology and hygi- ene may with great advantage be commenced in the primary schools. It is indeed true that physiology can be taught only in a very unsatisfactory manner to pupils ignorant of chemistry and physics, for physiology is essentially chemistry and physics applied to the complex structures and actions of the living body. But very imperfect knowledge is better than absolute ignorance. And the immense importance of the subject, in connection with the fact that only a very small minority of the pupils will ever reach the 902 Science-Teaching in the Schools. high school, more than justifies the attempt to teach some rudi- ments of physiology in the lower schools. Somewhat of physical geography will naturally be taught in the higher grades of the primary, and the lower grades of the gram- mar, schools, in connection with the general course in geography. It is very gratifying to observe the change in the school manuals of geography within the last few years, in respect of the greater prom- inence given to physical geography. In the higher grades of the grammar schools, it may reasonably be assumed that the reasoning faculties are more fully developed than in the lower grades, and observation and description of forms may rightly give place in large degree to studies in which the rela- tion of cause and effect is emphasized. This will be the most con- venient period for the introduction of exceedingly elementary courses in physics and chemistry. The pupils who will never enter the high school ought to get some rudimentary knowledge of these sciences; and a like rudimentary knowledge obtained in the gram- mar school will be of great advantage to the students in the high- school course. Of course, at this stage it will not be desirable or possible to penetrate into the mysteries of polarized light, to enu- merate the scores of rare elements, or to discuss the more intricate problems of the chemistry of the compounds of carbon. But 1t will be possible, in the later years of the course in the grammar school, to learn some of the more important facts and principles in regard to gravitation, the mechanical powers, the simpler and ‘more obvious phenomena of sound, light, heat, and electricity, the dis- tinction between elements and compounds, combustion, the chemis- try of air and water, and the properties of a very few of the most important elements and their compounds. When the student reaches the high school, he will be possessed of some knowledge of the forms of common animals and plants» the structure and functions of his own body, and the general prop- erties of matter. What is more important than any knowledge of nature which he may possess—he will have kept himself in sy mpa- thetic communion with nature; he will recognize nature as a WOT- thy object of study; he will know that he can learn something himself by the observation of nature, but that he has learned only an infinitesimal part of what nature has to teach. His conceptions will be crude, indefinite, inaccurate. His knowledge will require. Science- Teaching in the Schools. 903 elaboration, systematization, correction. But he will not find the book of nature written in a language whose alphabet he does not know. As he comes to the systematic study of the various sciences he will not feel that utterly bewildering sense of strangeness with which teachers in our high schools and colleges are now so sadly familiar. In the high school, he will come under the instruction of teachers possessed of larger knowledge, and supplied with more extensive material facilities, Now then the time has come for sys- tematic teaching of science. Random observation and desultory stories of nature must now give place in large degree to the presen- tation of systematized bodies of fact and theory. With the beginning of the high-school course comes the separa- tion between those who are preparing for the classical courses in the colleges, and those who are destined to go from the high school directly into practical business life. For the former class the sys- tematic study of science may be mainly deferred until they can enjoy the larger material facilities afforded by the laboratories, museums, and observatories of the colleges. I believe, however, that the complete exclusion of scientific studies from the classical courses in many of our high schools is greatly to be regretted. There are three scientific studies which I would have placed early in the high-school course, and required of both the English and the classical students. First in this list I would name phenogamic botany. There is no study which can conveniently be made to furnish so admirable a discipline in observation. The material is everywhere accessible in abundance. The collection and dissection of the specimens involves no infliction of pain upon sentient creatures. The débris remaining after a lesson is comparatively clean, inodorous, and wholesome. In all these respects phenogamic botany is better adapted for thorough practical study at this stage than any branch of zoology. The structures which are to be examined in the ana- lysis of flowering plants are also of about the right size to afford the most valuable discipline in accurate observation. The work is neither too easy, nor too difficult. It requires the use of the inex- pensive simple microscope, but not the use of the costly compound microscope. A thorough training in plant analysis at this period of the educational course will afford a mental discipline which can be supplied in no other way. 904 Science-Teaching in the Schools. Secondly, I would require of all students at this stage the study of human physiology. The immense practical importance of this branch of knowledge is a sufficient reason for this recommenda- tion. The outlines of physics and chemistry which I suppose to have been taken in the later years of the grammar-school course, will enable the teaching to be more thoroughly scientific in method than can be the case in the lower schools. And, while the study cannot be made so much of an observational discipline as botany, there is no lack of material for demonstration. Most of the organs of the body present the same general character in other mammals asin man. Hearts, lungs, brains, and eyes can readily be obtained from the butchers, and a superfluous cat can be occasionally sacri- ficed. And, with the various convenient guides to mammalian dis- section which have been published, there is no reason why a high- school course in physiology may not be illustrated with a fair amount of demonstration. Thirdly, a systematic study of physical geography will be inval- uable in giving the student an appreciation of the world as a whole —its unity in variety—unity of law amidst endless diversity of phenomena. No study so opens to the student’s intelligence the language of nature, teaching him to read the lessons written in the ever varying landscapes which he may from time to time behold. It is, in my judgment, greatly to be desired that these studies should be included in the requirements for admission to the colleges. As students naturally desire to enter college as early as possible, there is a strong tendency for the preparatory schools to exclude from their classical courses everything not required for admission to college. The requirement of a small amount of natural science by the colleges would greatly favor the progress of the reform in the schools. : For the students in the high school who are not in the classical course, there should be in addition systematic studies of physi, chemistry, zoology, geology, and astronomy. For them, natural science should certainly be a required study during the whole of the high-school course. While the study of natural science has been advocated on the twofold ground of its practical and its disciplinary value, it has assumed in this discussion that these two objects are by no means of equal relative importance in the study of different branches Science- Teaching in the Schools. 905 of science or in different periods of the educational course. The study of botany has been advocated especially for its disciplinary value, that of physiology especially for the utility of the knowledge which is acquired. It has been maintained that in the primary school the main objects of the science lessons must be to culti- vate a habit of accurate observation and intelligent appreziation of nature, while in the high school each science should be taught as a systematic body of fact and theory. This leads us to notice the unfortunate truth that the two objects of scientific study are to a certain degree incompatible with each other—that the best methods for mental discipline are not the best methods for the acquisition of information. Undoubtedly the method by which the characteristic mental discipline of scientific study can be most effectively secured, is to put ihe student as nearly as possible in the attitude of the original investigator—to lead him to infer laws and principles from the observations and experiments which he has made himself. But the path taken by the original explorer of a country is often not the most convenient route for subsequent travelers. And a knowledge of laws and principles in science once ascertained can often be taught in ways far more expeditious and convenient than the method of their original discovery. More- over, many of the most important conclusions rest upon observa- tions only possible in exceptional conditions of time, place, and circumstance. Every student should learn the laws of definite and multiple proportions, which form the foundation of chemical theory ; but the ordinary student has no time to perform such a number of experiments in quantitative analysis and synthesis as would make a sound inductive basis for those laws. Every student should learn something of the phenomena and laws of earthquakes. and volcanoes; but it is impossible to get up an earthquake or a volcanic eruption for a laboratory experiment. It is well for every student to learn something of the conclusions in regard to the action of the stomach reached by the classical observations on poor Alexis. St. Martin; but it is hardly desirable to repeat St. Martin’s acci- dent and injury for the benefit of every class in physiology. The right method of scientific education must be a compromise. The most important facts and principles must be taught by text-books and lectures, in such way as to secure most effectively their being understood and remembered. But, so far as the nature of the sub- 906 Science-Teaching in the Schools. ject and the time and means at the disposal of the teacher may allow, mental discipline must be secured by having the student tread for himself the path of observation and experiment, compar- ison and inference. This difficulty in science-teaching is somewhat relieved by the consideration that a single fact learned by actual observation or experiment, serves to render real the knowledge of allied facts made known by the second-hand process of description, which would otherwise be shadowy and unsubstantial. The student who has made a few quantitative determinations in chemical analysis, under- stands the meaning of the analyses which he finds in books. The student who has handled the bones of one animal, can read intelli- gently the description of other skeletons. In conclusion, I would most emphatically repeat that a plea for the study of natural science is not a plea against other studies, All the studies which have a place in the educational course, have their place by reason of their capacity to afford sound mental discipline and useful knowledge. All true education is broadening and liber- alizing in its tendency. Whatever the special studies which natural tastes or professional plans may lead the student to pursue in the later years of his educational course, or whatever the pursuits in which he may engage after leaving school, he will have learned, - if rightly taught, an appreciative respect for all the great branches of study in which the human intellect has engaged. He will not despise the study of languages, bringing him into communion with the great minds of other ages and other nations; nor the study of language, interpreting the structure and development of earth’s myriad tongues. He will feel the dignity of that pure truth which is embodied in mathematics, and will appreciate the immense utility of the applications of mathematics in the arts of a material civili- zation. He will have learned in due time that he has a soul as well as a body; and will appreciate the study of the human mind, er revealed to the direct gaze of consciousness, or as expressing 1 in literature and history. And the double world of sensation and consciousness will disclose to him its highest meaning, in the reve- lation of Him : “ Whose dwelling is the light of setting suns, And the round ocean, and the living air, And the blue sky, and in the mind of man.” Science- Teaching in the Schools, 907 But, whatever sources of light may shed their beams upon his advancing intellect, the first star which rose above his horizon will never set. Whatever teachers he may listen to, the one whose gentle voice first roused him from the slumber of unconsciousness will never be forgotten. As his first lessons were from nature’s teach- ing, she will have for his expanding mind lessons continually new, He will ‘ Find tongues in trees, books in the running brooks, Sermons in stones, and good in everything.” Note.—It-is proper to say that the address was not written pre- viously to its delivery before the Society of Naturalists ; and that, in writing it in its present form, I have incorporated some ideas which were suggested in the discussion at the meeting, and some which have been the fruit of further reflection. The article is, however, in the main a reproduction of the address as given. In July, 1888, the Board of Education of the City of Middle- town, Conn., adopted a new Manual for the Schools of that city. The new course of study provides for instruction in Natural Sci- ence in all grades from the lowest Primary upward, on a plan sub- stantially the same as that which I have recommended, As a sort of practical comment on the views of the address, I append an extract from the Middletown School Manual, giving the instructions to the teachers in the Primary and Grammar grades in regard to instruction in Natural Science. The portion of the Manual here quoted was written by myself in connection with the Superintendent of Schools, W. B. Ferguson, M.A. EXTRACT FROM THE MANUAL OF THE PUBLIC SCHOOLS OF MIDDLETOWN, Conn. NATURAL SCIENCE. Introduction —The object of elementary lessons in Natural Sci- ence is twofold :—to train the observing powers, and to give infor- “mation. The former should be especially emphasized in the Pri- mary Grades, and the two made about equally important in the Grammar Grades. The teaching should be chiefly objective. Large, well-defined pictures may be used, whenever it is impossible to obtain the real objects ; but it shold always be borne in mind that the best pic- tures are poor substitutes for the objects themselves. 908 Seience-Teaching in the Schools. In the lowest grades, the teacher should studiously avoid the use of technical terms, whose meaning is unknown to children. The chief object here is, not to teach science, but to train to close and accurate observation, and to stimulate a keen interest in nature. In no grade should special emphasis be laid upon technical terms and classifications, though somewhat more attention may properly be given to them in the Grammar grades. All classifications should, so far as possible, be the result of observation and compar- ison on the part of the pupils. Let the teacher stimulate, direct, and name. Happy the teacher and fortunate the pupils, if, in this delightful work, the teacher judiciously combines speech and silence. An occasional talk, however, by the teacher on the subject before the class is both proper and desirable. Such talks should furnish information beyond the reach of the pupils’ observation. Every lesson should be carefully prepared. Aimless and irrele- vant conversations are profitless. Allow and encourage the freest expression of what the pupils see. Encourage the pupils to collect and bring in specimens. Elicit, by judicious questions, a description of what they have brought. Give them additional information. If necessary, postpone the subject till the next day, and learn something about it. GRADE I. Physiology.—Regions of the body—head, trunk, limbs. Details of external parts. Uses of external organs. Hygiene of the skin —bathing. Zoology.—Lessons on common mammals—e.g., cat, dog, horse, cow, rat, squirrel.

Let the pupils find the elbow, wrist, knee, and ankle, in the cat, dog, horse, cow, rat, squirrel, and any other mammals of which specimens or pictures may be at hand. Thus teach the idea of homology, though the word should not be used. Compare the teeth of common mammals, and lead pupils to recognize adaptation of different kinds of teeth to different kinds of food. Teach pupils to recognize degrees of resemblance between animals, The cat and the dog resemble each other more than either resembles the horse or the rat. Develop idea of classifica- tion. Lead pupils to recognize characters of carnivores, ungulates, rodents. Most of the mammals with which the children are famil- iar are included in these three orders. But tell them about mon- keys and kangaroos and other very different forms of mammals, that they may not suppose that all mammals are so included. Botany.—Different kinds of stems—woody and herbaceous, exo- genous and endogenous. By study of numerous examples lead pupils to recognize that exogenous stems usually bear net-veined leaves, and endogenous stems usually bear parallel-veined leaves. Distinguish deciduous and evergreen trees. Let the pupils make lists of each. | GRADE III, Physiology.—Elementary ideas of digestion. Why do we eat? _ All parts of the body are made of the food which we eat. Food is made into blood, and blood made into all the materials of the body. But our food is mostly solid, and must be made liquid before it can get into the blood. Different substances dissolve in different liquids—e.g., salt in water, camphor gum in alcohol, iron filings in dilute sulphuric acid. Show these experiments. Body itself must make liquids which will dissolve food. Put lump of sugar in mouth. Mouth fills with saliva, and sugar is dis- solved. This illustrateś secretion of digestive fluids.

Wholesome and unwholesome foods. Alcohol. Zoology.—Lessons on common birds—e.g., robin, hawk, hen, duck. Let pupils compare these with each other and with mam- mals. Compare feet and bills of different birds, and show adapta- tion to habits. Continue lessons on homology of limbs. Let the pupils find elbow, wrist, knee, and ankle, in birds. Is the bat a bird? Talks on instincts of birds shown in periodical migrations and nest-building. Botany.—Lessons on flowers. Select plants with perfect and somewhat conspicuous flowers. Teach pupils to recognize sepals, petals, stamens, pistils. Let pupils describe and draw the parts in a variety of flowers. Study polypetalous flowers first, afterwards — monopetalous flowers. Cut open the ovary in large flowers, and show the ovules. Develop the idea that the parts of a flower are altered leaves. . GRADE Iv. Physiology.—Circulation.

THE PINEAL EYE IN EXTINCT VERTEBRATES. BY E. D. COPE. ie discovery of the pineal eye in lizards is due to Leydig, who first recognized it as a probable sense organ in 1872. Dr. Graaf first determined its structural correspondence with the inver- tebrate eye in 1886. In the same year! Spencer examined a large series of Lacertilia, and pointed out the very diverse degrees of development of this organ presented by these reptiles. In 1882 Prof. Rabl!Ruckhard refers to the large parietal foramen of Ichthy- osaurus and Plesiosaurus as indications of the existence of a pineal sense organ in those ancient reptiles, perhaps especially sensitive to temperature. In the NATURALIST for 1885 (p. 1029), the present writer stated that the Pelycosauria of the Permian epoch possessed large pineal eyes. Mr. Spencer expresses a similar opinion with regard to the extinct Stegocephala or labyrinthodonts of the carbon- iferous system, in his paper above mentioned. He there maintains also the homology of the median eye of the Tunicata with the epiphysis of the Vertebrata. In a paper published in the Naturauist of 1885 (p. 291), the present writer described the characters of the supposed fish Bothri- olepis canadensis, and homologized the orifice in the superior wall of the anterior part of the carapace (supposed to represent the head) with the orifice or mouth in a corresponding position in the Tuni- cata, especially referring to Chelyosoma, as having a general resem- blance to Bothriolepis. I mention (p. 290) that a plate covers the middle part of this orifice, forming a median valve of the mouth, a character which is also described by Whiteaves in 1887.2 It was already described in the allied Pterichthys by Pander and Owen. This plate covers the median part of the superior orifice, and leaves the lateral parts open. It has little fixity in the specimens I have examined, for which reason I called it a valve. See plate XV. Subsequently I described the genus Mycterops* from the coal 1 Mr. tne paper is dated 1885, although he quotes De Graaf’s and my own papers published in 1886. ws Tlustrations of the fossil Fishes of the Devonian Rocks of Canada: Transac.

Pineal Eye in Extinct Vertebrates. 915 measures of Pennsylvania (Plate XV), which is intermediate in the character of the anterior regions between Cephalaspis and Bothri- olepis. The median orifice of the latter genus is present, and its middle portion is roofed by a plate. But this plate differs from that of Bothriolepis and Pterichthys, in being perforated by two orifices, which resemble in their position nostrils, while the lateral orifices have the position of the eyes of the Cephalaspidide. Under these circumstances the evidence in favor of the orifices in Bothriolepis being eyes, is stronger than that which points to its homology with the mouth of Tunicata. The structure of these primitive vertebrates strongly indicates the origin of lateral or paired eyes from a single median eye, such as is found in the Tunicata, and continues to point to the descent of Bothriolepis from those ani- mals. Mycterops indicates a wider divergence than Bothriolepis ; and Cephalaspis a still further stage of modification. Dr. Dollo, of Brussels, has expressed the view that the superior orifice of Pter- ichthys corresponds with the median eye of the Tunicata and the pineal eye of the Reptilia. Of course, if the median eye of the Tunicata became specialized into the lateral eyes of higher vertebrates, it might seem improbable that it could be at the same time homologous, as there are no em- bryological reasons for refusing to believe (Spencer), with the pineal eye of the same forms, which possess also the lateral eyes. It may not be impossible, however, that this is really the case, and that the paired eyes, as well as the pineal eye, have been formed by evagina- tion of differentiated parts of the Tunicate eye, so that the views of Lankester and Spencer may be both correct. The formation of the lens from two parts in the Tunicates, which precludes its corres- pondence with the pineal lens in Reptilia, probably has a significance in this connection, expressing the origin of the lateral eyes, while the retinal portion is homologous with the pineal retina. In extinct American Batrachia: bate ee foramen is wanting in Eryo; 1Za trachys, and | ved in Trimerorhachis; but it is well developeds i in Cricotus, the genus that leads probably to the Reptilia. Among North American extinct reptiles I have described the characters ' of the cast of the brain case in two widely distinct forms. 1 Proceeds. Amer. Philos, Soc., 1886, p. 234. 916 Pineal Eye in Extinct Vertebrates. These are Diadectes,! a Permian genus of Theromora, and Belodon, a Parasuchian crocodile. The former has an immense parietal foramen, while the latter has none. The general characters of the brain in Diadectes are as follows : The widest part is at the origin of the trigeminus nerve. Both the cerebellum and nesencephalon are flat, and simple. The hemispheres are narrower than the segments posterior to them, and of greater vertical diameter. The epiphysis is enormous, and its flattened posteriorly extending peduncle is very distinct. The olfactory lobes were apparently large, and had a greater transverse diameter than the hemispheres. The reduced diameter of the hemispheres is a character of fishes and Batrachia rather than of reptiles, but the thalami are also smaller than is the case in Batrachia. The small, flat cerebellum is rather batrachian than reptilian. (Plate X VI.) There is some reason to suspect that the Diadectes relied exclu- sively on the pineal eye for the sense of sight. The species of the family were subterranean in their habits, since their humeri indicate great fossorial power, resembling those of the existing monotremes, and even the mole. The vertebre are locked together with the hyposphen beside the usual articulations, and the arches of the neural canal form an uninterrupted roof from the skull to the tail, of extraordinary thickness and strength. That the species are not aquatic is rendered probable by the fact that the orbits do not look upwards. Their superior borders are, on the contrary, promi- nent and straight. Add to this fact the apparent absence of optic foramina, and the probability that the Diadectide were blind and subterranean in their habits becomes still stronger. Belodon is a genus of reptiles which belongs to the sub-order Parasuchia of Huxley, which has been generally associated with the Crocodilia. It is characteristic of Triassic formations. Three species have been found in Europe, three in Eastern North America, and two in the Rocky Mountain region. One of the latter, Belodon buceros Cope, is represented in Plate XVII. It was about as large a8 the Gangetic gavial. As in Crocodilia generally there is no parietal foramen. Differently from crocodiles of later ages, the nostrils are posterior in position, and near the orbits, so that the nose might be plunged deeply beneath the surface of mud or water without inter- 1 Loe. cit., 1887, p. 219.

The characters of the brain are as follows: The first point which arrests the attention in making a compari- son with Diadectes is the similarly huge size of the epiphysis in the two types. A foramen on each side of the base of the epiphysis in the Diadectes gave exit to a process similar to that which enters the orbitopineal canal in the Belodon, and which I called the lateral process of the epiphysis in the latter. Plate XVIII, figs. 1-3, 1 f). _ The processes are probably homologous in the two genera, but in the Belodon they extend through the posterior wall of the orbit, fill- ing a large canal. There is little resemblance between the two brains in other respects, but they agree in the small size of the prosencephalon, and in the complete enclosure of the rhinen- cephalon by osseous walls. In the Diadectes there is no optic foramen, but a huge trigeminus; in Belodon, an optic foramen, and a very small trigeminus. The presence of such a huge epiphysis in the Belodon, as com- pared with its very small size in modern crocodiles, is a point of much interest, and points to its inheritance from the reptiles of the Permian. But if, as is probable, it contained the pineal eye, the latter could not receive light directly from above, since the parietal foramen is wanting. The presence of a communication with the orbit becomes interesting in this connection. A minute foramen passes from the base of the rhinencephalon into the orbit in the alligator, but the homology with the canalis orbitopinealis of Belo- don is by no means made out. The nervus orbitopinealis may have supplied the lack of light due to the closure of the parietal foramen, but in what way we are left to conjecture. The equality of size of the brain of the Belodon to that of the existing alligator is a point of interest. The Belodons were probably aquatic reptiles, living on the shores of estuaries like modern crocodiles, and were of carnivorous habits. @ 918 Editors’ Table. EDITORS’ TABLE. EDITORS: E. D. COPE AND J.

The appropriation for a Governmental Zoological Garden at the Capital has been defeated in the House of Representatives, not because of any objection to the proposition, to the location, to the site, nor to the necessity, but solely because of the money it would cost. It was simply the wail of a miser. The benefit from, in fact necessity for, a Governmental Zoological Garden was conceded. The time and opportunity were apropos. It was not denied that the manage- ment was in proper hands. No argument was made against the project save that it would cost money, and this was played ad nau- seam. The opponents of the project raised their voices and fairly wept over this great expenditure of money. We attempt no homily on the duties of a legislator, nor to explain how it is sometimes as much his duty to spend money as it is at others to save it. The United States, with a greater territory» greater riches, and with undoubtedly greater opportunities, is behind third and fourth-rate kingdoms in the matter of zoological gardens. The Materiaux pour Vhistorie de P Homme for August has an article entitled “ Extinction of the Buffalo,’ in which it notices a capture or massacre, in the Territory of Arizona, of a herd of buffalo (Bos americanus), and says, “The race is now practically extinct.” It laments that these are not the only zoologic forms in America which have become so, and closes, “ The Republic of the United States of America is less careful of its opportunities, and pays less regard to its duty to science than does the Russian Empire, where the Euro- pean bison of pre-historic times lives under the protection of the Czar.” If the two or three gentleman who led the opposition, and the fifty-six members who voted with them, shall continue the defeat of the project, and thus the buffalo become an extinct animal, with others now threatened, the descendants of these gentlemen will have Jittle cause for pride in this act of their ancestors. There never will be a time when this project can be carried out Recent Books and Pamphlets. 919 more opportunely than at the present. Each year that it is post- poned increases the expense. Many people stand ready now to aid it with contributions of animals, Ifa place were but provided in — which the animals could be kept and cared for, the Garden would soon fill up. But with the passage of time these opportunities will also pass, and the difficulties and expense correspondingly increase. RECENT BOOKS AND PAMPHLETS. Aep, D.

AS gs oF GRAVITY IN APPROACHING THE CENTRE OF ANY Cosmic SPHERE WHATEVER.—First, within a hypothetical hollow hitar a solid shell of which is, in all parts, of ual the gravity of Q, and g lr the gravity of q: then wil will mie qr: G : g, and there results Q X g = G X q, or g = a 922 General Notes. Now, if, in our hypothetical hollow sphere, we assume any point whatever, and draw a line through that point to the nearest and most distant points of the shell, this line will be a straight line, and the longest that can be drawn in the sphere ; hence it passes through the centre, and is the diameter. Now, pass a plane through this assumed point and perpendicular to the diameter, cutting the shell into two segments, corresponding to the two segments of the diameter made by the assumed point. Let R equal one segment of the diameter, and r equal the other; let Q equal the segment of the shell corresponding to R, and q equal the segment corresponding tor: then, since, by hypothesis, the density and thickness are everywhere equal, there results Q : q: : : 7’, and Q °? = q R’; but gravity varies in proportion to the duplicate ratios of the reciprocals of distance, R and r. t represent the gravity of the segment R? X q, and g represent the gravity of segment r° Q, at the assumed point, then we have G: 1 1 g::——:——-; therefore, G R? q =g r°’ Q. Now, since Qr Rg Q = q R? G = g: ie., gravity, at any point whatever, in this hollow point assumed: then will result G: gy: : R? : 1°; g = R? nM the centre r equals 0 and g = 0. They vanish together. _ As a matter of fact, however, this proportion and equation = true for two points only: viz., at the surface, when R = r, h the centre, when r = 0. y? Because the density varies wi the pressure, in the first place. Though the weight, i. e., the gravity, relative to that sphere alone, is greatest at the surface, in the hae of any given quantity of matter, yet, under the superimcum i pressure, the density of the inner sphere, composed of the sam matter, is greater than that of the entire sphere. : ‘ Again, the heavier matter, ie., the matter of the highest — ravity, during the process of free centralization, naturally 0. ys the nucleus of the sphere, throwing the lighter ma i surface, as we see in case of our earth. Thus, for two reasons, Geology and Paleontology. 923 centres of all cosmic spheres are of higher specific gravity than the surfaces. On the contrary, after solidification has taken place, by virtue of thermal radiation into the infinite of space, the high degree of internal heat tends, very considerably, to diminish the density of the interior. The complexity of this problem is not amenable to mathe- matic resolution. Even the elastic resiliency of the most persistent gases increases more rapidly than any assumed amount of pressure. Thus, if the pressure increases as the natural series 1, 2, 3, 4, ete., the elastic resilience is such that the resulting volumes are not 4, 4, , 4, etc., nor anything like it, except in the very lowest of the series. Still we are warranted in all cases in saying that the greater the pressure the greater the density for the same kind of matter. ow,a few words on the formation of a solid crust over a molten sphere are entirely pertinent. It has been held by some authors that no crust can form over such a sphere; for, say they, when the surface cools it is heavier than the molten mass within, and must necessarily sink ; so that the centre would become solid first. First, here is a palpable reductio ad abswrdam ; for this would necessarily result in cooling so as to solidify at the centre first. Can any rational mind accept this absurdity ? nd, ejected lavas always cool on the surface first, while yet the deeper portions are molten even so as to flow long after a solid crust has been formed. Thus does direct observation show the gold. Cold silicon can not sink in molten iron, Yet, all the lighter materials are on and form the outside of earth, and of every other sphere where they exist. Unless there may exist a cosmic sphere of pure gold or pure platinum, or something of that kind, their hypothesis can never be realized. : Fourth, these lighter materials are highly non-conductive to heat, and hence husband the internal heat most providentially ; so that earth will continue to have an internal heated core for raising mountains, continents, islands, etc., eons to come, as it thus far has had during eons past. Fifth, the dream of those other philosophers, that all the waters of all the oceans will disappear to the centre of earth, cannot be realized, unless the outer non-conductive materials are in excess of the heavier central materials, which the higher mean gravity of earth seems to contradict. Sixth, this fact of heavier central materials insures the molten condition of a portion of the centre, in spite of all contrary hypo- 924 General Notes. theses. Through these heavier materials conduction is rapid, and the maximum is easily maintained. Mark! I saya portion of the centre, for the centre is unquestionably solid, as a resultant of pressure, the temperature being the maximum attained at the point of liquefaction. As the inner portion consists of the heavier materials, which are also far better conductors of heat, and ren- dered still better conductors under the immense pressure of the superincumbent materials, this solid nucleus will maintain, by con- duction, this maximum temperature throughout. Finally, it may not be void of all interest to take a very brief view of earth’s outer envelop. The entire outer shell, as all know, consists mainly of two persistent gases—oxygen and nitrogen ; oxygen, a constantly active, ever varying, yet constantly nearly the same in proportion; and nitrogen, a neutral dilutent for the active oxygen. With these two are mingled a few other substances, most conspicuous of which is watery vapor. Next is a shell—a little broken—of water. This is followed, in the descending order, by a shell of mingled substances, the common rock materials. These are very poor conductors of heat. The lighter of these materials do not form a very thick mass. As the entire mass of earth, including all these, has a much higher specific gravity than any of these, it follows that heavier materials soon begin to take the place of these; nevertheless, this outer envelop must be sufficient to protect the heated nucleus, and volcanic emissions show that their seat is not below this outer shell, but in it. —Ira Sayles, Ithaca, N. Y., March 12, 1888. (To be continued.) THE ATTACHMENT OF PLATYCERATA TO Foss, CRINOIDS has been long known, but the hitherto extreme rarity of illustrative specimens has necessarily occasioned only brief explanatory remarks. nasmuch as the gasteropod shell was invariably situated on the crinoidal vault, and covering the ventral opening, which was erro- neously regarded as the mouth of the crinoid, conclusive evidence of the carnivorous habits of the crinoideans was thought to be established. Other explanations were from time to time offered, but for the most part they were also fallacious, and originated in wrong conceptions relative to the true functions of certain structures l the group of echinoderms. Opportunity has recently offered for the examination of an extensive series of palæocrn- oids with attached Platycerata, embracing numerous specimens of the following species: Ollacrinus tuberosus Lyon and C., O. typus Hall, Physetocrinus ventricosus Hall, Strotocrinus regalis Hall, Doryormus immaturus Wachsmuth and Springer, Marsupiocrinus cælatus £ hit- Geology and Paleontology. 925 lips, Eucladocrinus millebranchiatus Wachs. and Sp., Platycrinus hemisphericus M. and W., Arthroacantha punctobrachiata Wil- liams, Pterotocrinus acutus Weth., P. bifurcatus Weth., P. spatula- tus Weth., Cromyocrinus simplex Trauts., Scaphiocrinus sp. und. and Actinocrinus verrucosus Hall. It will be observed that in all the above species, with two exceptions, the vault is more or less depressed or nearly flat, with a simple anal opening, while in the last species mentioned the anal aperture is at the extremity of a prolonged anal tube—the so-called “ proboscis ”—but in this single instance the tube appeared to be injured, and probably has a second opening at the base. In every example, whether attached to the vault, as in the majority of the genera, or to the side of the calyx, as in Platycrinus, the molluscan shell is situated over the anal: opening. Summing up the predominant physiological and structural features suggested by recent investigations, it appears: (1) that the Platyceras was attached to the crinoid for a considerable length of time, and very probably for life, as is evidenced by the margin of the gastropod shell, corresponding exactly to the irregularities of the crinoidal surface—first suggested by Meek and Worthen ; (2) that the anterior portion of the shell is always directly over the anal aperture of the crinoid, and that as growth in the shell con- tinues the posterior margin is removed farther and farther from the vault opening, as is shown by the shallow concentric channels made y the margin of the shell in the vaults of Strotocrinus and Physe- tocrinus ; (3) that the nourishment of the mollusc must have been derived chiefly from the excrementitious matter from the crinoid, though the gasteropod may have subsisted also on animalcules and microscopic plants, as in the case of the living representatives of the closely allied genus Capulus ; (4) that the shape of the shell aperture and its marginal configuration were dependent entirely upon the surface of attachment, and hence are of small classificatory ' value; and 0) that the entire form of the shell was determined to a greater or lesser extent by the surface upon which the gasteropod was stationed. The species of Platyceras in which the sedentary habits are posi- tively known from the attachment of the gasteropod shells to crin- oids are: P., equilaterum Hall, P. infundibulum M. and W., P. parasiticus Trauts., P. erectum Hall, P. formosum Keyes, P. ches- terense M. and W., P. dumosum Conrad, and several undetermined species.— Charles R. Keyes. GLYPTOCEPHALUS NOT IDENTICAL WITH BucKLANDIUM.— In the AMERICAN NATURALIST for May and September, 1888 (Vol. XXII., pp. 448, 828), I have used the name Bucklandium (Keenig) as a substitute for Glyptocephalus of Agassiz (1843), the latter name 926 General Notes. having been previously given to a well-marked existing genus of Pleuronectids by Gottsche (1835). I did this, as indicated in my communication (p. 828), solely on the authority of Pictet, who believed that the Bucklandium was the same as Glyptocephalus Agass.,! the work of Koenig not being accessible to me at the time, and Prof. Pictet being recognized as a special authority on eocene fishes. But in the Geological Magazine for Oct., 1888 (p. 471), and also in The Annals and Magazine of Nat. History for Oct. (6 ser., v. II, p. 355), Mr. A. Smith Woodward, after an examination of the type of Bucklandium diluvii, “determined that it is truly the im- perfect head and pectoral arch of a Siluroid.” | Incredible as such a malidentification on the part of Pictet must appear, I presume the determination of Mr. Woodward must be accepted, and, at any rate, that the name Bucklandium has nothing to do with Glyptocephalus, Consequently, a new name must be provided for Glyptocephalus Agass. Glyptocara, having the same meaning, may be employed. —Theo Gill. Dr. C. A. White, of the United States Geological Survey, writes the senior editor as follows :—“ I have just returned from Texas. I went to Baylor, Archer and Wichita counties, and found that Mr. Cummins was entirely correct in his reported discovery of Mesozoic and Paleozoic types of invertebrates commingled in one and the same layer of the Permian. I went with him to his localities, and collected with my own hands a good lot of the fossils. I shall support your published opinion—or rather determination— as to the Permian age of the formation.” THE NOMENCLATURE OF THE MAMMALIAN MOLAR CusPs.— Every fresh discovery among the primitive mammals tends to con- firm the theory that the evolution of the molar crowns has been, 1n a succession of stages, beginning with the single reptilian cone, the homodont type of Riitimeyer (Haplodont Cope). Comparative anatomy and the paleontological record combine to demonstrate this Multituberculates and Edentates—the history of the teeth of the former classes is incomplete. Our knowledge of the edentates leaves it uncertain whether the molar crowns are in a primitive 2 degenerate condition; we know that they once possessed eg ; but the analogical degeneration of the molar crowns among the cetacea from a complex to a primitive type makes any cone > to the crowns of the primitive edentates very doubtful. Exclu ing the representatives of the Multituberculata, Cope has shown 1 Je crois que C'est [i.e., “Glyptocephalus radiatus Agass.’’] 1a mon espèce que celle qu’il a Avie date les Icones sectiles, pl. 8, sous e Lp de Bucklandium.

Geology and Paleontology. 927 that the tritubercular stage, in one form or other, is universal among the known lower Eocence Mammalia. In a recent memoir, I showed that a large proportion of the Mammalia of the Mesozoic period, again excluding the Multituberculates, were in the line of trituberculy, and a renewed examination of the English types removes every one of the apparent exceptions to this law. Among the American Jurassic types there are still several apparent excep- tions. ; In view of the evidence for the almost universal presence of the tritubercular stage in the present or past history of the upper and lower molars, I have already advocated a distinct nomenclature for the different cusps which compose this molar and its derivatives, up to the stage of the acquisition of six tubercles in the upper molars and five in the lower. This is the final stage in which the tubercles reman distinct. The nomenclature now in general recog nized at once that the antero-internal cusp of the lower molar of Mioclænus is not homologous with the antero-internal cusp of the upper molar of the same genus, nor is it homologous with the antero-internal cusp of the lower molar of Hyopsodus. e nomenclature proposed is based upon the fact that the cusps composing the main triangles are homologous with each other . and that some of the cusps superadded to these to form respectively the six and five tubercled mı slars, have probably originated in a similar manner. The terms for the three main cusps are selected to indicate, as far as possible, the primitive position and the order of evolution. The lower molar cusps are arbitrarily distinguished rom those of the upper molars by the termination id. Terms proposed. Terms now in use. Up. Molars. Low. Molars. Upper Molars. Lower Molars.

MINERALOGY AND PETROGRAPHY.! PETROGRAPHICAL News.—The basaltic rocks of Alsace, accord- ing to Linck}? embrace feldspathic and non-feldspathic varieties. Of the latter a limburgite from Reichenweiler contains a glassy base, which deports itself towards reagents like nepheline, a fact which would cause the rock strictly to be classed among the nepheline basalts. Its olivine yields upon analysis :— SiO, AO; . Fe; 0, FeO MgO Na,O 41.53 2.33 0.58 10.27 43.60 1.69, indicating a replacement of part of the magnesium of the typical molecule by aluminium and sodium. Olivine concretions occurring in this rock consist of olivine, bronzite and a bottle-green augite containing 2.64 per cent. of K,O and 2.41 per cent. of Na,O.— rief notes on the rocks of Fernando Noronha, an island in the Atlantic about two hundred miles north-east of Cape St. Roque, Brazil, are communicated from the laboratory of the Johns Hop- kins University by Mr. Gill? The rocks described are phonolites, from conical hills similar to those in the Hegau in Baden, nephe- ` ine-basanites and basalts, nephelinite, and finally basalt glass. A extended petrographical study of these in all their different varie- ties will be published later.— Although the rocks of the Bohemian Mittelgebirge have been made the subjects of study by several pet- rographers, Hibsch‘ finds something new to say of them in a late article in T'schermak’s Mittheilungen. The trachytes of the region are younger than the phonolites or the basalts and occur in but a few localities. Their porphyritic sanidines possess a rounded out- line and are fringed with a rim of newly formed secondary feld- spathic substance. Many of the phonolites contain a large amount of plagioclase, and have besides a trachytic habit. In their cavi- ties is often noticed quite an interesting development of secondary albite. Little crystals of this mineral extend out from the sides of the cavity and penetrate into a mass of analcite, which, together ' Edi . W.E. iversi aterville, Me.

Sandberger,’ who has found blocks of the same rock, states that the epidote is more likely an alteration product of hornblende or augite, as it is associated with asbestus, while the red orthoclase is still fresh A grammatite rock occurs,’ interstratified with phyllite, in the Bohemian Fichtelgebirge, between lein- Wenden and Sichersreuth.—The third paper on the rocks of the Cortlandt Series, in the Hudson river, embraces‘ the treatment of the gabbros and diorites associated with the peridotites and norites which have been described in another place. The gabbros present no peculiar features other than the granulation of some of their constituents. Two types of diorite are distinguished. One, containing brown hornblende, tends to pass into gabbro, norite, or hornblendite. The other, containing green hornlende, is closely related to mica-bearing rocks. The mica-diorites (Dana’s soda- granites) are essentially coarse-grained aggregates of plagioclase and biotite, with often a little orthoclase and quartz, and sometimes garnet as a metamorphic mineral. The plagioclase has a specific gravity between 2.67 and 2.65, and is sometimes twinned, while at other times it is entirely free from twinning lamelle. The most noticeable feature in the rock is the occurrence in it of a pale green, non-pleochroic epidute, which appears to be original. The mineral is generally without terminations. It is strongly corroded on its ges as if eaten into by a liquid magma. The paper closes with a graphic representation of the close relations, which the author, Dr, Williams, has found to exist between the various eruptive members of this series.

It occurs in the serpentine, which is directly connected with the grains of olivine from which it has been derived. rere is every reason to believe that the nickel silicate came from the same source. A study of the Webster Co., N. C., and the New Caledonia nickel deposits indicate the same origin for the ores at these places.—A feldspar from Kilima-njaro, similar to that from the rhombic porphyry of Chris- tiania, has been analyzed by Fletcher.’ Its composition is :— SiO, Al,O, CaO Na,O K,O 62.17 23.52 2.90 6.80 4.61, corresponding to a mixture of the anorthite, microcline and albite molecules in the proportions An, Or., Al,..,. The extinction on the clinopinacoid is about 4° 20’. On the basal plane it is parallel to the clinopinacoid cleavage. In sections cut parallel to the ortho- inacoid the microcline structure is visible.—Sandberger? calls attention to the properties of the carbonaceous material in the erys- talline limestone of Wunsiedel in the Fichtelgebirge, as those of an amorphous substance corresponding to the graphitoid of Inostran- zeff and Sauer. The hardness of the mineral is 3 and the specific gravity 2.207.

MORPHOLOGICAL AND PHYSICAL MINERALOGY.—Since almost all of our knowledge of the morphological properties of markasie depend principally upon the measurements of Hausmann and Sade- ek, and since these mineralogists disagree in their results, Geh- macher” has thought it worth while to measure the crystals in his possession, and from these measurements to recalculate the planes occurring in them. He finds the axial ratio to be: .7623 : 1 : 1.2167. The formulas of the different planes are determined, and other obser- vations are made which indicate a monoclinic symmetry for the mineral.—Zepharovich’s® measurements of trona crystals from Lake Lagunillas, Venezuela, show their axial relation to be: * Min. ea ee July, 1887, and Zeits. f.

Their composition corresponds to that of the same mineral from other localities——Very pure idri- alite (C,,H;,,O,), crystals from Idria in Krain, consist of small plates bounded on two sides by parallel planes. The extinction against one of these sides is 5° 33’, and the optical angle of the min- eral, measured in oil, is 2H = 101° 20’. The interference figure is that of a biaxial crystal, with the bisectrix perpendicular to the surfaces of the plate.—A great many observations have been made by Niedmann! upon barite in order to determine the relations between the elasticity and the other physical properties of the mineral. He finds the direction of greatest elasticity to be per- pendicular to the plane of easiest cleavage. The shape of the curve representing the relative values of the coefficients of elasti- city for any given plane, corresponds in all cases to the symme- try of the orthorhombic system. MIscELLANEOUS.—In a late paper Dr. Cohen? discusses critically the arguments in fayor of the chemical theory of deposition for gold in placers, and also those in favor of its mechanical origin. He gives the main facts bearing on the subject, and shows that some of those whlch have always been cited as favoring the chem- ical theory, are of doubtful existence. It has been stated, for Instance, that placer gold always contains less silver than vein gold from the same region, Analyses of specimens from Buttons Creek, in the South African gold-fields, however, prove that this is not always the case. Dr. Cohen’s results are :— Au Ag Cu Insol Vein gold 94.48 5.16 ged x Placergold {95:02 1.60 1 o7 He thinks that whereas placer gold, for the most part, is derived by the breaking down of gold veins, there is occasionally in addi- tion a deposition of the metal from its solutions. This, however, he regards as playing but a subordinate rôle in the formation of placer gold.—A ‘meteoric stone,’ found in the San Emigdio mountains in California, is composed of chondri of olivine and anstatite, imbedded in a base composed of the same minerals in a . fragmental condition. Nickeliferous iron constitutes 6'21 per cent. of the stone, It occurs in lumps and masses, often surround- ing the chondri.

Boveri believes that the course of karyokinetic division may be generally described in the following terms :—The chromatic nuclear material becomes collected together with a definite number of isolated pieces of a form characteristic of the kind of cell—the chromatic elements; an achromatic filamentar figure is formed in the two poles, either from the substance of the nucleus or from that of the cell. The chromatic elements, so far as their number, form and size allow it, are deposited in the equa- torial plane of the achromatic figure ; the chromatic elements divide into two halves, one of which makes its way toward either pole; the daughter elements break up in the framework of the new nuclei. ments of the next spindle. n the germinal vesicle of the ovum of Ascaris megalocephala (Carnoy’s type), two independent portions of chromatin are found in the earliest known stage. Though nothing is certainly known of their mode of formation, it may be assumed that they are derived from a typical nuclear framework. This conversion, however, of the reticulum into the chromatic elements, which in other cells and in some ova (A. lumbricoides) directly precedes division, appears, in most eggs, to take a long time. e important difference in the eges of the type of Van Beneden is that there is but one chromatic element ; this seems to be unique. indication of the achromatic figures of division. The most striking of these cases has been lately described by Flemming. Similar phenomena have been observed by the author in the eggs ° Ascaris. n the germinal vesicle of Ascaris lumbricoides the Zoology. 933 twenty-four rods exhibit the most distinct transverse division long before the germinal vesicle begins to be converted into the spindle. After considering several cases in different forms the author expresses his belief that they form parts of a series in the degenera- tion of the process of nuclear and cellular division. In the case of Corydalis cava, described by Strasburger, the process is least rudi- former. Nervous SYSTEM OF THE Srarrisn.—Dr. Carl F. Jickeli 934 General Notes.

Two specimens were collec ted in some brush land bor- dering a creek in the vicinity of Custer, Dakota, by Mr. Vernon Bailey, in July last, Examination of their teeth shows them to belong to the subgenus Myonomes.

MorLuscs.—The crystalline style is a peculiar structure found in a pocket developed from the stomach of certain lamellibranch molluscs. Many theories have been advanced as to its nature and physiological functions. Möbius maintained that it was a reserve food supply, and recently (Biol. Centralblatt, 1888) Haseloff has experimented on Mytilus edulis, in which the structure is almost constantly present. He starved some individuals for a few days, and found that the style had disappeared. Others of the same starved lot were afterward fed with abundant food, and on examina- tion were found to possess the style. Haseloff regards the style as a chemical modification of surplus food rather than a secretion. MaLacopopa—Peripatus comes in for several papers recently.

ScuppEr’s BUTTERFLIES oF New Encianp.’2—Thelong-looked- for work by Mr. Scudder, on the butterflies of New England, is about to appear. We are in receipt of a prospectus which includes sample pages and plates. Judging from this the work will su in fulness of detail and magnificence of illustration anything of the kind yet published ; and the scope of the work is an unusually broad one, including accounts of the structure of these insects in all stages of life, their variation, habits, manners, life-history, and their enemies ; also frequent discussions of problems suggested by their study. 1 This department is edited by Professor J.

This work was at first intended to embrace only the butterflies known to occur in New England or its immediate confines ; but it has been extended so as to include in its descriptions and histories some account of all the butterflies of North America, east of the Missis- sippi, excepting such as are found only in the uasettled parts of anada, or south of Kentucky and Virginia. Not only every species, but also every genus, tribe, sub-family, and family, are described and discussed with a fulness never before attempted, except in individual cases. The descriptions include in each instance not merely the perfect form, but when possible, the eggs, the caterpillar at birth and in the succeeding stages, and the chrysalis, together with the distribution, life-history, habits, and environments of the insects. A great accumulation of new facts and observations are embodied. Analytical tables applicable to every stage are used wherever possible. Over seventy distinct execursuses, distributed throughout the work, discuss separately all the interesting problems which arise in the study of butterflies (whether of distribution, structure, history, or relation to the outer world), in themselves forming a complete treatise on the life of these insects. Judging by the fragment of the excursus devoted to dimorphism and polymorphism which is given in the prospectus, this part of the work will be of the highest interest to those who study entomology in a scholarly way, whatever their specialty. very page of this treatise bears evidence of the wonderful amount of pains-taking labor devoted to its preparation. For twenty years the author has been at work upon it ; and for the last eight years it has received his undivided attention. No one else has brought to the study of this group of insects more scholarly attainments, nor has achieved such magnificient results. We trust that the work will receive the recognition that it deserves. VISION OF CATERPILLARS AND ADULT Insgcrs.—Prof. F. Plateau continues his researches on the powers of vision by an m- vestigation of caterpillars and of the frontal ocelli of adult insects. 1) He made a series of experiments and observations on iL caterpillars of fifteen species of Lepidoptera, and obtained the pe lowing results: (a) The eyes of caterpillars have a more importan rôle than that of simply distinguishing between light and darkness. They really see, though badly. (b) The distance of distinct visio” is short, and usually about a centimetre. (c) At greater distances caterpillars can perceive large masses, but do not discern mre nature. (d) They only perceive the movements of bodies ee the limits of distinct vision. (e) Tactile hairs present on : anterior segments of many forms are of much sensory importance. ‘ Bull. Acad, R. Sci. Belg. xv. (1888), pp. 28-91. Entomology. 939 (f£) The antenne are much used in testing the path and surround- ing objects. | (2) In the next chapter Prof. Plateau discusses the function of the frontal ocelli of adult insects. He gives an historical summary of past researches, describes the manifold conditions of his own observations and experiments, submits tabulated results of his investigations of different forms, and formulates the following con- clusions: (a) Diurnal winged insects, Hymenoptera, Diptera and Lepidoptera, when blinded by covering the entire eyes with black or by cutting all of the optic nerves, rise to a great height in the air when liberated. (b) When the compound eyes are suppressed, but the frontal ocelli left, in Hymenoptera, Odonata, and Diptera, the insects behave exactly as if the ocelli also had been suppressed. When freed, they rise vertically as before. In a chamber lighted from one side they behave as if they were totally blind. (c) But if the frontal ocelli be alone suppressed, the above insects hehave as if they had lost nothing. (d) In diurnal insects equipped with compound eyes the ocelli count for almost nothing. They only afford the animals very feeble perceptions which they do not know how to. use. The author concludes his memoir with the following suggestions, which he describes as “ plausible hypotheses,” supported by a cer- tain number of observed facts: (1) Diurnal insects, in which all of the eyes have been suppressed, still enjoy dermotoptic perceptions. (2) They are almost reduced to the same limitations if the ocelli are left at their disposal. (3) The dermotoptic perceptions are the primary cause of the ascending flight of liberated blinded insects. (4) The frontal ocelli serve neither for the perception of movements in adjacent objects, nor for the perception of light in relative obscure media. (5) The simple eyes, which the author has shown to func- tion in an imperfect fashion in most Myriapods, in many Arachnids, and caterpillars, have entirely lost their utility in the great majority of insects equipped with compound eyes.

Lire or TOWNEND Guover.—A biographical sketch and an account of the writings of the late Towend Glover, the first United States Entomologist, written by Mr. Charles R. Dodge, has just been published by the Department of Agriculture at Washington.? Mr. Dodge was for a long time the assistant of Mr. Glover, and was one of his most intimate friends during the wis, "aes of his life. He is, therefore, well fitted to ney Pas this office and has done it in a very satisfactory manner. The work is illustrated by a portrait of Mr. Glover, copies of two of his earlier plates, and by several of his humorous caricatures. Numerous anecdotes are given 1 U. S.

Following the biographical sketch is a chapter giving the history of Glover’s great work entiiled Illustrations of North American Entomology. There is also a short chapter on the Glover Museum, and a list of Mr. Glover’s entomological writings ; this includes sixty-four titles. MONOGRAPHS OF NORTH AMERICAN SPIDERS.—We have re- ceived during the past month two monographs of North American Spiders. The larger of the two is of the family attidæ and is by George W. and Elizabeth G. Peckham. It is reprinted from the Transactions of the Wisconsin Academy of Sciences, Art and Letters, Vol. VII. It comprises 104 pages and is illustrated by six plates. An analytical key to the genera is given, and the specific descrip- tions are evidently very carefully prepared. The smaller monograph is of the family Ciniflonide and is by J. H. Emerton. It is reprinted from the Transactions of the Con- necticut Academy, Vol. VII. It comprises sixteen pages and is illus- trated by three beautiful plates. Tue Ber-Keerers’ GUIDE.—A new edition of this excellent manual of the apiary by Prof. A. J. Cook has just appeared. The work has been wholly re-written and revised, 150 pages and more than thirty illustrations being added. The greatest additions are in the chapters pertaining to the natural history of the honey-bee. We are glad to note also an improvement in the paper and press work. This is undoubtedly our best manual on the subject and it should be in the hands of every American bee-keeper. Supplement of June 2, 1888, an important paper by Prof. Riley on the scientific relations of Platypsyllus as determined by the larva. The paper is based upon the study of larve collec Prof. Riley by Mr. Lawrence Brunner in Nebraska. Three figures of the larvee are given, and one of the adult.

ON THE PRIMARY SEGMENTATION OF THE GERM-BANDS OF Ixsrcts.?—Prof. Veit Graber summarizes his important results on the embryology of insects as follows :— 1. The germ-band of insects is at first either discoidal (Steno- bothrus, Œcanthus), or is oblong (Hydrophilus, Lina, ete.). The primitive discoidal germinal area corresponds principally to the (Urkopf) antennal segment, since the (Urrumpf) primitive body as at first very limited dimensions. n most insects with an elongate germ-band, the primitive head-segment is also the first to be separated. An exception to this is found in Lina—if Hydrophilus is not taken into account—in which two transverse furrows appear simultaneously, forming three principal segments, which appear to correspond to the principal subdivisions of the insect body (head, thorax and abdomen). 3. The primitive body (Urrumpf) of the germ-bands of Steno- bothrus and Cicanthus does not segment, as it has been assumed in the case in all insects hitherto, but before the permanent segments (metameres or microsomites) are established, the latter definitive segmentation is preceded by a subdivision into two and then three large segments (macrosomites). ` _ 4. Of these three primary segments (macrosomites) of the primi- tive body, the first corresponds to the sum of the jaw-bearing (gna- thophorous) metameres—gnathal macrosomites—the second, the sam of the limb-bearing metameres—thoracic macrosomites—and finally the third to the abdomen—abdominal macrosomites. i In the process of the primary or macrosomitic segmentation of the primitive body there is no external segmentation, that is transverse subdivision of the ectodermal plate, but a total segmen- tation of the inner (lower) layer, the hypo- (or ento-) blast. ao 6. The secondary or microsomitic segmentation of the primitve body (segmentation of the microsomites into metameres) does not proceed in Stenobothrus and Lina (and also in spiders according to Morin), as is generally assumed, from before backwards, but it first involves the middle or thoracic (Ursegment) macrosomite. e may finally inquire as to the morphological significance of the primary subdivision into four or tetramerism of the germ- bands of Stenobothrus and Œcanthus. !

T, 942 General Notes. Since the two last primary segments (Ursegmente), namely, the thoracic and abdominal, correspond to the two sections of the body of the perfect insect, we may regard the primary segmentation as an anticipation of the later or tertiary segmentation. Against such a view two important facts are opposed. First, it is not to be for- gotten that the primary segmentation does not conform to the tre- tiary, in that the head in the former does not constitute a primitive segment, but is divided into two sharply distinguished and hetero- geneous sectious, the primitive head segment (Urkopf ) and the gna- thophorous macrosomite. Secondly, against the hypothesis alluded to, the whole progress of segmentation is opposed. If the macrosomites of the primitive body were to persist, as such, together with their later subdivisions (microsomites), as stem-unities of a higher order, the above view would be to some extent justified. The relation is, however, alto- gether a different one, in that between the few and unequally seg- mented stage on the one hand, and the similarly segmented end- stage on the other, a many and unequally segmented middle stage is intercalated, which bears scarcely a recognizable trace of the ear- lier segmentation, and out of which the trimerism of the end-stage is developed anew by the fusion of certain groups of metameres. the tetramerism of the segmented primary stage may not be readily explained by the not very sharply expressed trimerism of the end-stage, its cause must, without doubt, be sought in certain definite conditions of segmentation of the ancestors of insects. But, as I would eSpecially point out, may the tetramerous germ- band stage here under consideration be compared with other adult similarly segmented arthropods without taking other matters into account, since, independently of the fact that our germ-band is not an independent (completed) living organism, there is wanting all support toa legitimate comparison of its macrosomites with other arthropods with few segments, such as the Nauplius, for example. ARCH ZOLOGY AND ANTHROPOLOGY.’ (Continued from page 856.) Dr. Brinton presented a human vertebra from Tampa’ Bay, Florida, found in the bog deposits of the quarternary geologic period. Its peculiarity was that the bony structure had p and been replaced by a deposit of iron called limonite, so that it was an iron instead of a bone vertebra. ' This department is edited by Thomas Wilson, Esq., Smithsonian Institution, Washington, D. C. Archeology and Anthropology. 943 Mr. Wilson said that the National Museum possessed the lower half of a human skull from the same neighborhood which had been treated in the same way. It was found associated more or less intimately with fragments of fossilized bones and teeth of the mastodon. Prof. E. S. Morse, of Salem, Mass., read a paper, which he illustrated to the audience with a bow and arrow; showing a new system, the third in his series, of “ Arrow Release.” Rev. W. M. Beauchamp displayed some Indian relics from central New York. Prof. Joseph Jastrow, of the University of Wisconsin, read a most interesting paper on the “ Psychology of Deceptions.” He de- scribed deceptions practised upon the senses and said the founda- tion of legerdemain was to distract the attention by an unimportant operation from the critical moment wherein the vital change is made. He entered the domain of spiritualism but dealt with arà that portion which was an evident deception, and had been exposed. The first general principle in these deceptions is that the medium performs to spectators in doubt as to the interpretation to be placed upon the scene which they witness, and are more or less ready to ascribe it to the supernatural. This mental attitude of the specta- tors is worth more to the medium than any factor in the perform- ance. The difference between a spectator in this state of mind and one convinced of the fraudulent character of the manifestations and seeking to discover how the fraud is committed is very grea t.- When the medium recognizes this condition of mind in the spec- tator the sitting will always bea blank. If the investigator is once convinced that he has evidence of the supernatural he soon sees it in every accident and incident of the performance; not only does he overlook natural physical explanations but the supernatural idea soon leads him to create marvels with sincerity. Thus, the believer, seeing a carelessly arranged drapery by a dim light thinks he recog- nizes in it the spirit of a dear friend or a well-known acquaintance. he same object is frequently recognized by different members o the circle as entirely different and wholly dissimilar persons. Little by little, through the neglect of observation, caution is abandoned, credulity takes possession of the spectator, and he is able to see Impossibilities. Finally a fantastic explanation is considered more probable, the bounds of the normal are passed, and the believer having eyes sees not, and ears hears not, even the realities which happen before his face. If this seems impossible, turn back to the history of witchcraft. In the afternoon the section met to hear Prof. Otis T. Mason, of the National Museum, Washington, D. C., deliver his lecture on Women’s Share in Primitive Industry.” It was illustrated by Photographs projected upon the screen by the lantern, of woman in 944 General Notes. her different spheres of industry through savagery, barbarism, civili- zation, and into the heavens where she is deified and appears as a god evening.

Garrick Mal- lery, of the Bureau of Ethnology, Washington, and for Secretary, Rev. W. M. Beauchamp, of Baldwinsville, New York. The committee appointed at last general meeting to secure from Congress the abolition of the customs duties on scientific books an apparatus, made a lengthy report in favor thereof. The committee on the preservation of archæologic monuments on public lands reported in favor of the following as proper subjects for preservation: Chaco cañon from the forks of Escavoda cañon for a distance of eight miles up, also one mile back from the brink of the cañon walls on each side so as to include many interesting staff, A. T. Besides these groups of ruins and dwellings there are isolated remains in the territories of New Mexico, Arizona and After the usual resolutions and speeches of thanks and ri edgements to the local committee and to the citizens of Cleveland, the meeting adjourned sine die. Microscopy. 945 MICROSCOPY.: Mrnor’s AUTOMATIC MICROTOME.—The principle of this Micro- tome is to obtain sections by moving the object to be cut in a ver- tical plane past the knife which is held in a fixed position. The knife is clamped by two screws in jaws at the top of two upright pillars to be seen in the figure. The object to be cut is imbedd in paraffine and stuck on to a circular brass plate which faces the knife, when the plate is in position. This plate has the motion in three directions, and may be revolved around its own centre, so that the position of the object may be adjusted as desired. The well- known construction, used on the Schanze Machines, has been adopted to secure the necessary play of movement for the plate, carrying the paraffine. This construction was selected on account of its simplicity and convenience, and the great firmness with which the plate may be clamped. The object holder rests on a horizontal plate which may be fed towards the knife by a micrometer screw, the head of which is a toothed wheel. Hach tooth equals ybg mm. forward movement. The whole of this complete object-carrier is fastened to an upright slide. The slide is worked up and down by a crank, as seen in the cut, and the crank is moved by turning a heavy iron wheel. 1 Edited by C. O. Whitman, Director of the Lake Laboratory, Mil- Waukee, Wis. 946 General Notes. When the wheel is revolved, the crank is turned, and the upright slide rises and falls in a vertical plane, and of course the object- carrier, with its micrometer screw, rises and falls with it. As the carrier rises a lever connected with a pawl strikes against a screw on a separate pillar ; the pawl catches in the toothed wheel-head of the micrometer screw and so turns it, and moves the paraffine towards the knife. As the carrier descends a section is cut off, when it is near the top of its upward excursion, the micrometer screw is turned by the pawl, and the next descent produces another section. By simply turning the screw against which the pawl lever strikes, the number of teeth caught by the pawl, and therefore the thickness of the sections may be varied from 1-300 to 1.33 of a millimeter. This microtome has been devised to avoid the obvious inconve- niences attaching to the rocking and other automatic microtomes. Since the first lot of these microtomes were placed in the market, some important improvements have been made, among which may be mentioned the strengthening of the upright slide in which the carrier moves. This improvement secures regularity and precision in the movement of the object, and renders the microtome one 0 the best for paraffine-cutting now in the market. This microtome, with one knife in case, is supplied by the Educational Supply Com- pany, 6 Hamilton Place, Boston.

Microscopy. 947 equal measure of alcohol, never the reverse, and the mixture should be kept cool, otherwise the acid may attack the alcohol. In such an event the solution is rendered worthless, and, should the speci- mens be in it at the time, the heat generated by the reaction gives the acid such additional dissolving power that the sections are at once destroyed. A more efficient acid reagent is a mixture of equal parts hydrochloric and nitric acids. A 35 per cent. solution of this mixture in strong alcohol gives better results than the pure nitric acid at 50 per cent., and does not so readily attack the alcohol. Of the alkalis, weak ammonia, sodic hydrate, and potassic hydrate are most serviceable. The solids are to be preferred to the ammonia, since from them solutions of a definite strength can more easily be made. An aqueous solution of $ or } per cent. potassic hydrate has given the most satisfactory results. The method of using the depigmenting fluid is as follows. Unstained material is cut in paraffine; the ribbons are mounted on a slide with Schallibaum’s fixative ; when the sections are fixed, the araffine is removed with turpentine; the slide with the sections is then successively washed with alcohol of 98 per cent., 90 per cent., 70 per cent., and so on, till a grade homogeneous with the depig- menting fluid is reached. Into a shallow white dish filled with the depigmenting fluid the slide is now gently lowered. Ina few seconds the pigment, dissolving, will be seen as a reddish cloud. ‘The process 1s usually completed in less than a minute, and the slide is promptly transferred to a dish of clean water or alcohol and there gently rinsed, The sections are next stained by exposure to the dye ina shallow dish. After being sufficiently stained, they may be washed and mounted in glycerine, or, after the proper steps in dehydrating -e : clarifying, mounted in benzol-balsam or other mounting ium. The dyes which have been found the most serviceable are some of the carmines and hematoxylin. The aniline dyes have almost invariably given poor results. For general purposes Grenacher’s alcoholic borax-carmine is excellent. In both embryonic and adult material Czoker’s alum-cochineal gave fine nuclear outlines. In =~ the adult eyes, the rhabdomes and the cell boundaries were most distinctly shown by Kleinenberg’s hematoxylin. A’ very faint col- a oration with this dye gave the best results for nerve-fibres. et For the isolation of the retinal elements two maceration fluids __Were used. A weak solution of chromic acid, as employed by Pat- retina, after the removal of the lens and surrounding tissue, was placed oy this treatment, 948 General Notes. which slightly hardened the tissues, the first solution was replaced by a second of =! per cent. In this the retina remained for three or water, rinsed, and transferred to Grenacher’s alcoholic borax-car- mine. This reagent performs both the office of a maceration fluid andadye. In from twelve to twenty-four hours the retinal cells can be isolated, and present in different regions of the retina three principal conditions. First, those from the exterior of the retina are seriously altered by the continued action of the potash ; second, ose from the centre of the retina remain almost unchanged, still Proceedings of Scientific Societies. 949 SCIENTIFIC NEWS. —The President has directed Maj.

The results of the congress are thus summed up by the President, Professor Prestwich :— e said: We approach the end of the congress, and we can now congratulate ourselves upon the results obtained. The first sitting was devoted to the discussion on the divisions of the Cambrian and Silurian systems, and although no vote has been taken, the opinions expressed have demonstrated that all are in accord for retaining the three groups or zones of Barrande and Murchison. But the neces- sity is not seen of making, as some members proposed, the interme- diate zone a separate system. Thus the status quo of the Upper and Lower Silurian for the beds as far as the Tremadoe, and of the Cambrian for the group below, will not be affected. Two sittings have been devoted to the discussion on the origin of the crystalline schists by hydrothermal chemical action or by movements, for each o which causes powerful arguments have been advanced. The congress had received and printed in advance memoirs by eminent geologists, which will be valuable documents in the solution of this important problem. Another sitting took cognizance of the connection between the Tertiary and the Quaternary, the result of which 1s that, although opinions are divided, the majority of members approve of retaining the term Quaternary. Although in these cases votes had not been taken, the discussions had a great interest in the demonstration of the ideas which predominated among the most distinguished geologists. According to the resolutions adopted by the Committee on Voting, it will be easier in the future sessions to arrive at more positive conclusions. The reports which the Committee of Nomenclature has received from the national wpa mittees, and which are printed, are of great importance, and wil serve as bases for a more settled classification. It is to be regretted also that the great paleontological work of all the known fossils = about to be abandoned for the present, by reason of the grea expenses which it involves. One of the most inrportant objects of the congress has been brought to a conclusion—the unification of colors and shadings in maps, and the Committee on the Geological er i of Europe announce to us that the publication of this fine map wW! not be delayed. ee Some six hundred members were registered, of whom one hundr and forty-two were from countries other than- Great Britain.

BY WILLIAM DAWSON.: GEOLOGICAL RELATIONS OF THE FLORAS. N my memoir in the First volume of the Transactions of this Society, I have given a table of the formations prepared by Dr. G. M. Dawson, and have fully stated the geological position of the plants at that time described. The new facts above detailed now require us to intercalate in our table three distinct plant horizons not previously recognized in the western territories of Canada. One of these, the Kootanie series, should probably be placed at the base of the table as a representative of the Urgonian or Neocomian, or, at the very least, should be held as not newer than the Shasta group of the United States Geologists, and the Lower Sandstones and Shales of the Queen Charlotte Islands. It would seem to cor- respond in the character of its fossil plants with the oldest Creta- ceous floras recognized in Europe and Asia, and with that of the Komé formation in Greenland, as described by Heer. No similar flora seems yet to have been distinctly recognized in the United States, except, perhaps, that of the beds in Maryland, holding cycads, and which were referred many years ago by Tyson to the Wealden. ! This paper states the general conclusions of a memoir, by Sir William Dawson, in the Transactions of the Royal Society of Canada, which will appear with descriptions and illustrations of the new species in the Course of next winter. 954 Cretaceous Floras of Canada. The second of these plant horizons, separated according to Dr. G. M. Dawson, by a considerable thickness of strata, is that which he has called the Mill Creek series, and which corresponds very closely with that of the Dakota group, as described by Lesquereux, and that of the Atané and Patoot formations in Greenland, as described by Heer. This fills a gap indicated only conjecturally in the section of 1883. Along with the plants from the Dunvegan group of Peace River, described in 1883, it would seem to represent the flora of the Cenomanian and Senonian divisions of the Creta- ceous in Europe. Above this we have also to intercalate a third sub-flora, that of the Belly River series at the base of the Fort Pierre group. This, though separated from the Laramie proper by the marine beds of the Pierre and Fox Hill groups, more than 1,700 feet in thickness, introduced the Laramie or Danian flora, which continues to the top of the Cretaceous, and probably into the Eocene, and includes several species still surviving on the American continent, or repre- sented by forms so close that they may be varietal merely. Lastly : the subdivision of the Laramie group, in the last report of Dr. G. M. Dawson, into the three members known respectively as the Lower or St. Mary River series, the Middle or Willow Creek series, and the Upper or Porcupine Hill series, in connection with the fact that the fossil plants occur chiefly in the lower and upper members, enables us now to divide the Laramie flora proper into two sub-floras, an older, closely allied to the underlying Belly River series ; and a newer, identical with that of Souris River, described as Laramie in Dr. G. M. Dawson’s Report on the 48th Parallel, 1876, and in the Report of the Geological Survey of Canada for 1879, and which appears to agree with that known in the United States as the Fort Union group, and with the so-called Miocene of Heer from Greenland. From the animal fossils and the character of the flora, it would seem probable that the rich flora of the Cretaceous coal fields of Vancouver Island is nearly synchronous with that of the coal- bearing Belly River series of the western plains. It will thus be seen that the explorations already made in Cana- dian territory have revealed a very complete series of Cretaceous plants, admitting, no doubt, of large additions to the number of species by future discoveries, and also of the establishment of con- Cretaceous Floras of Canada. 955 necting links between the different members, but giving a satisfac- tory basis for the knowledge of the succession of plants and for the determination of the ages of formations by their vegetable fossils.

The Dunvegan series of Peace River prob- ably corresponds in time with the M Niobrara G farther South v 956 Cretaceous Floras of Canada. In connection with the above table it should be understood that Tertiary floras, probably Miocene in age, are known in the interior of British Columbia, though they have not yet been recognized in the territories east of the Rocky Mountains. | Before leaving this part of the subject I would deprecate the remark which I see occasionally made, that fossil plants are of little value in determining geological horizons in the Cretaceous and Tertiary. I admit in these periods some allowance must be made for local differences of station, and also that there is a generic same- ness in the flora of the Northern Hemisphere, from the Cenomanian to the modern, yet these local differences and general similarity are not of a nature to invalidate inferences as to age. No doubt palæo- botanists seem obliged, in deference to authority, and to the results of investigations limited to a few European localities, to group together, without distinction, all the floras of the later Cretaceous and earlier Tertiary, irrespective of stratigraphical considerations, the subject lost its geological importance. But when a good series has been obtained in any one region of some extent, the case becomes different. Though there is still much imperfection in our knowl- edge of the Cretaceous and Tertiary floras of Canada, I think the work already done in Canada in connection with that of Lesquereux and Newberry in the United States, is sufficient to enable any com- petent observer to distinguish by their fossil plants the Lower, Middle and Upper Cretaceous, and the latter from the Tertiary- PHYSICAL CONDITIONS AND CLIMATE INDICATED BY THE CRE- TACEOUS FLORAS. In the Jurassic and earliest Cretaceous periods the prevalence, over the whole of the Northern Hemisphere and for a long time, of a monotonous assemblage of gymnospermous and Acrogenous plants, implies a uniform and mild climate and facility for inter- communication in the north. Toward the end of the Jurassic and the beginning of the Cretaceous, the land of the Northern Hemis- phere was assuming greater dimensions, and the climate probably becoming a little less uniform. During the close of this period oF at the beginning of the next, the dicotyledonous flora seems{to have been introduced, under geographical conditions which permitted @ warm temperate climate to extend as far north as Greenland. Cretaceous Florus of Canada. 957 In the Cenomanian, we find the Northern Hemisphere tenanted with dicotyledonous trees closely allied to those of modern times, though still indicating a climate much warmer than that which at present prevails. In this age, extensive but gradual submergence of land is indicated by the prevalence of chalk and marine lime- stones over the surface of both continents; but a circumpolar belt of land seems to have been maintained, protecting the Atlantic and Pacific basins from floating ice, and permitting a temperate flora ot great richness to prevail far to the north, and especially along the southern margins and extensions of the circumpolar land. These seem to have been the physical conditions which terminated the existence of the old Mesozoic Flora and introduced that of the Middle Cretaceous. As time advanced, the quantity of land gradually increased, and the extension of new plains along the older ridges of land was coinci- dent with the deposition of the great Laramie series, and with the origination of its peculiar flora, which indicates a mild climate and considerable variety of station in mountain, plain and swamp, as well as in great sheets of shallow and weedy fresh water. In the Eocene and Miocene periods the continent gradually as- sumed its present form, and the vegetation became still more modern in aspect. In that period of the Eocene, however, in which the great nummulitic limestones were deposited, a submer- gence of land occurred on the Eastern continent which must have assimilated the physical conditions to thdse of the Cenomanian. This great change, affecting materially the flora of Europe, was not proportionately great in America, which also by the north and South extension of its mountain chains permitted movements of migration not possible in the Old World. From the Eocene downwards, the remains of land animals and plants are found only In lake basins occupying the existing depressions of the land, though more extensive than those now existing. It must also be borne In mind, that the great foldings and fractures of the crust of the earth which occurred at the close of the Eocene, and to which the final elevation of such ranges as the Alps and the Rocky Moun- tains belongs, permanently modified and moulded the forms of the Continents, These statements raise, however, questions as to the precise 958 Cretaceous Floras of Canada. equivalence in time of similar floras found in different latitudes. However equable the climate, there must have been some appre- ciable difference in proceeding from north tosouth. If, therefore, as seems in every way probable, the new species of plants originated on the Arctic land and spread themselves southward, this latter process would occur most naturally in times of gradual refrigeration or of the access of a more extreme climate, than is in times of the elevation of land in the temperate latitudes, or conversely, of local depression of land in the Arctic, leading to invasions of northern ice. Hence the times of the prevalence of particular types of plants in the far north would precede those of their extension to the south, and a flora found fossil in Greenland might be supposed to be some- what older than a similar flora when found farther south. It would seem, however, that the time required for the extension of a new flora to its extreme geographical limit, is so small in comparison with the duration of an entire geological period that practically, this difference is of little moment, or at least does not amount to antedating the Arctic flora of a particular type by a whole period, but only by a fraction of such period, It does not appear that during the whole of the Cretaceous and Eocene periods there is any evidence of such refrigeration as seri- ously to interfere with the flora, but perhaps the times of most considerable warnith are those of the Dunvegan group in the Middle Cretaceous and those of the later Laramie and Paleocene. It would appear, that no cause for the mild temperature of the Cretaceous needs to be invoked, other than those mutations of land and water which the geological deposits themselves indicate. condition for example of the Atlantic basin in which the high land of Greenland should be reduced in elevation and at the same time the northern inlets of the Atlantic closed against the invasion of Arctic ice, would at once restore climatic conditions allowing of ms growth of a temperate flora in Greenland. Dr. Brown has shown, and, as I have elsewhere argued, the absence of light in the am winter is no disadvantage, since, during the winter, the growth 0 deciduous trees is in any case suspended, while the constant con” tinuance of light in the summer is, on the contrary, a very great stimulus and advantage. 1 Florula Diseana. Cretaceous Floras of Canada. 959 It isa remarkable phenomenon in the history of the genera of plants in the later Mesozoic and Tertiary, that the older genera - appear at once in a great number of specific types, which become reduced as well as limited in range down to the modern. This is, no doubt, connected with the greater differentiation of local condi- tions in the modern ; but it indicates also a law of rapid multipli- cation of species in the early life of the genera. The distribution of the species of Salisburia, Sequoia, Platanus, Sassafras, Lirioden- dron, Magnolia, and many other genera, affords remarkable proofs of this. Gray, Saporta, Heer, Newberry, Lesquereux and Starkie Gard- ner, have all ably discussed these points ; but the continual increase of our knowledge of the several floras, and the removal of error as to the dates of their appearance, must greatly conduce to clearer and more definite ideas. In particular, the prevailing opinion that the Miocene was a period of great extension of warmth and of a tem- perate flora into the Arctic, must be abandoned in favor of the later Cretaceous and Eocene; and if I mistake not, this will be found to accord better with the evidence of general geology and of animal fossils, 960 Influence of circumstances on the Actions of Animals. ON THE INFLUENCE OF CIRCUMSTANCES ON THE ACTIONS AND HABITS OF ANIMALS, AND THAT OF THE ACTIONS AND HABITS OF LIVING BODIES, AS CAUSES WHICH MODIFY THEIR ORGANIZATION. BY J. B. P. A. LAMARCK, ! Pe question here is not one of reasoning, but the examination of a positive fact, which is more general than is thought, and to which people have neglected to give the attention which it merits without doubt because, often, it is very difficult to recognize. This fact consists in the influence exercised by circumstances on the dif- ferent living bodies, which find themselves subjected to them. In fact, the influence of different states of our organism on our char- acter, our inclinations, our actions, and also our ideas, has been long remarked ; but it seems to me no one yet has recognized what influ- , ence our actions and our habits have upon our organization itself Now, as these actions and these habits depend entirely upon the circumstances in which we habitually find ourselves, I will attempt to point out how great is the influence which circumstances exercise on the general form, on the condition of parts, and thus upon the organization of living bodies. It is this very certain fact which is the question discussed in this chapter. If we had not had numerous opportunities to recognize clearly the effect of these influences on certain living bodies which we have placed in altogether new circumstances, and very different from those to which they were accustomed, and if we had not seen the effects and changes which have resulted, exhibiting themselves in many ways, under our eyes, the important fact in question would always have remained unknown to us. The influence of circumstances manifesting itself in bodies pos- sessing life, is effectual in all time and everywhere; but that which renders this influence difficult for us to perceive, is that these effects 1 Constituting the Chap. VII., Vol. I., of the Philosophie Zodlogique. Translated for the American Naturalist by Dr. Eleanor E. Galt, from the edition of 1809. Influence of circumstances on the Actions of Animals. 961 only become sensible or recognizable (especially among animals) after a long time. Before showing and examining the proofs of these facts, which deserve our attention, and which are of great importance to Philo- sophical Zoology, let us again take up the thread of considerations which we have already had in hand. In the preceding chapter we have seen that it is at present an incontestable fact that in considering the animal scale in an inverse sense to that of nature, we find that there exists in the bodies which compose this scale a continual but irregular degradation in the organization of the animals which compose it; a growing simplifi- cation of the organization of living bodies, and finally a propor- tional diminution in the number of faculties of these beings. This well-known fact throws the greatest light upon the order which nature has followed in the production of all existing animals ; but it does not point out to us why the organization of animals in its growing constitution, from the most imperfect up to the most perfect, shows only irregular gradation, of which the facies presents numerous anomalies or digressions, having no appearance of order in their diversity. Now, in searching for the reason of this singular irregularity in the growing constitution of the organization of animals, if we consider the result of the influence which circumstances, infinitely diversified in all parts of the globe, exercise on the general form, the parts, and the organization itself of the animals, all then will be clearly explained. It will be, in fact, evident that the state in which we see all animals, is, on one side, the product of the growing constitution of the organization which tends to form a regular gradation, and, on the other side, that it is the influence of a multitude of very different circumstances which are tending continually to destroy the regularity in the gradation of the growing constitution of the organization. Here it becomes necessary to explain myself as to the meaning which I attach to these expressions: The eirewmstances influence orm and organization of animals, that is to say, that in becoming very different they change in time both their form and their organ- wation itself, by proportional modifications. Surely, if these 962 Influence of circumstances on the Actions of Animals. - expressions were taken literally, an error would be ascribed to me; for, whatever the circumstances might be, they would not produce directly any modification whatever in the form and organization of the animals. But great changes in circumstances bring among animals great changes in their. wants, and changes in their wants necessarily bring parallel modifications into their actions. Now, if the new wants become constant or very lasting, the animals will adopt new habits, which are as permanent as the wants which produced them. This is a fact easy of demonstration, such as requires no explanation to be appreciated. It is then evident that a great change in circumstances becom- ing constant in a race of animals, entails upon these animals new habits, Now, if new circumstances becoming permanent with a race of animals, have given to these animals new habits; that is to say, have forced them to new actions, which have become habitual, the consequence will be the employment of some part, in pref- erence to some other part, and in certain cases the total lack of employment of a part which has become useless. Nothing of all this should be considered as an hypothesis, or a8 a private opinion; they are, on the contrary, truths which, in order to be rendered evident, require only attention and observation of facts. We shall see directly by the citation of known facts, which prove, on one side, that new wants, having rendered a certain p necessary, have really by repeated efforts created this part, and in consequence of repeated employment have little by little strength- ened and developed them, and have resulted in a considerable increase of size. On the other hand, we shall see that in certain cases new circumstances and new wants having rendered a certain part entirely useless, the total lack of employment of that part has caused its growth gradually to cease; that it becomes small and attenuated little by little, and that finally, when this lack of employment has been total for a long time, the part in question disappears. . : All this is certain, and I now propose to give the most convin- cing proof. In vegetables, which have no movements, and in conse- quence no habits, properly speaking, great changes of circumstances Influence of circumstances on the Actions of Animals. 963 bring great differences in the development of their parts, so that these differences create and develop some of them, whilst they diminish and abolish others. But here all goes on by changes wrought in nutrition of the vegetable, in its absorptions and its respirations, in the quantity of caloric, of light, of air and humidity, which it then habitually receives; finally in the superiority which certain of the diverse vital movements may exercise over the others. Among individuals of the same species, some of which are con- tinually well nourished, and under circumstances favorable to their development, while others are subjected to opposite conditions, there will he produced a difference of development which gradually becomes very well marked. How many examples could I not cite in regard to animals and vegetables which would confirm this asser- tion! Now, if circumstances remaining the same, render the state of badly nourished, suffering or languishing individuals habitual and constant, their interior organization is finally modified; and reproduction among these individuals in question preserves these acquired modifications, and at last gives origin to a race very distinct from that whose individuals are found continually in circumstances favorable to their development. A very dry spring is the reason why the grasses of a meadow grow very little and are meagre and mean, although they blossom and fruit. A spring time of warm and rainy days causes the same grasses to take on much growth, and the harvest of hay is then excellent. But if any cause perp: t- uates unfavorable circumstances for these plants, they will vary proportionally, at first in their appearance or general condition, and lly in various particulars of their characters. For example, if Some seed of any one of these grasses of the meadow in question, be transferred to an elevated locality, dry, arid, stony, and much exposed to winds, and there germinate, the plant which wil] live in this locality, though always badly nourished, and the indi- viduals which it reproduces then continuing to exist under these adverse circumstances, there will result a species very different from the species living in the meadow, from which it has originated. The individuals of this new race would be small, slender in their parts, and certain of their organs having developed more than others, would then present peculiar proportions. 964 Influence of circumstances on the Actions of Animals. Those who have observed much, and who have consulted great collections, have been able to convince themselves that, according as the circumstances of habitat, of exposure, climate, nourishment and habit of life, etc., change ; the characters of size, form, proportion of parts, color, consistence, activity and labors, of animals change in proportion. That which nature does slowly we can do every day, by changing suddenly, in the case of a living vegetable, the circumstances by which it and all the individuals of its kind are surrounded. All botanists know that vegetables which are taken from their native place into gardens to be cultivated, gradually undergo changes which render them finally unrecognizable. Many plants naturally very hairy become smooth, or nearly so; numbers of those which were creeping and trailing, straighten their stems ; others lose their spines or their roughness; still others possessing woody and long-lived (perennial) stems in warm climates which they inhabited, pass, in our country, into an herbaceous state (many are only annual plants); finally the dimensions of their parts undergo very considerable changes. These effects of changes of circumstances are so well known that botanists do not like to describe garden plants unless they have been recently culti- vated. Is not cultivated wheat (Triticum sativum) a vegetable, brought by man to the state in which we actually see it? Who can tell me in what country a like plant has its habitat without being there the result of culture? Where do we find in nature our cabbages, our lettuces, ete., in the state in which we possess them in our kitchen gardens? Is it not the same in regard to many animals which domestication has changed or considerably modified? How many different races among our poultry and domestic pigeons have we procured by raising them under diverse circumstances and in different countries, and how vain would be our search to find such in nature! Those which are the least changed, without doubt by less ancient domestication, and because they do not live in a climate strange to them, present no less, in the condition of certain of their parts, great differences, produced by habits which we have caused them to contract. Thus our domestic ducks and geese find their type in wild ducks and geese; but ours have lost the power to rise high in the air, and to traverse great distances by flying ; there has been, in fact, a real change in the state of their parts, com- Influence of circumstances on the Actions of Animals. 965 pared with those animals of the race from which they came. Who does not know that any bird of our climate which we have raised in a cage, and which has lived there five or six years, continuously, when liberated is not able to fly as its kind who have always been free? This trifling change of circumstance acting on this individ- ual, has in truth only diminished its faculty of flight, and without doubt has made no change in the form of the parts of the individ- uals, But if successive generations of individuals of the same race had been held in captivity during a considerable time, there is no doubt that even the form of the parts would little by little have undergone notable changes. A stronger reason yet, if instead of a simple captivity maintained in regard to them, this citcumstance has been for some time accompanied by a change of very different climate, and that these individuals by degrees had been habituated to other kinds of food, and to other movements to get it, certainly these circumstances united and become constant would have formed insensibly a new race altogether peculiar. Where is found now in nature the multitude of races of dogs which, in consequence of the domestication to which we have reduced them, have been brought into the condition in which they are at present? Where are found the bulldogs, greyhounds, spaniels and lapdogs, etc., races which show in themselyes greater differences than those which we would admit as specific among animals of the same genus living at liberty in nature? Without doubt a first and unique race, first cousin of the wolf, if not himself the true type, has been some time tamed and domes- ticated by man. This race, which showed at that time no differ- ence among the individuals, has been gradually dispersed with man into different countries and into different climates, and after having long submitted to the influence of the places of habitation and the diverse habits which they have been made to contract in each coun- try, they have experienced remarkable changes and have formed peculiar races, Now man, for the sake of commerce or for other interests, travels great distances; and having transported into well- peopled places, as a great capital, different races of dogs bred in countries far apart, and then crossed them, he has by generation given origin successively to all these which we now know. The following fact proves, in regard to plants, how the change 966 Influence of circumstances on the Actions of Animals. of some important circumstance acts to change the parts of these living bodies. While Ranunculus aquatilis is immersed in water its leaves are all finely divided and the divisions are capillary, but when the stems of this plant reach the surface of the water, the leaves which develop in air are enlarged, rounded and simply lobed. If some root of this plant succeeds in pushing itself into a soil only damp, without being covered by water, the stems are short, and none of the leaves are parted into capillary lobes; it is called the Ranunculus hederaceus, which botanists regard as a species when they encounter it. There is no doubt that, in regard to animals, important changes in the circumstances in which they are in the habit of living, produce changes likewise in their parts, but here the mutations are slower in being brought about than in vegetables, and in consequence are less evident to us, and their cause less recognisable. Among the circumstances which have so much power to modify the organs of living bodies, the most influential are, without doubt, the diversity of places which they inhabit; but besides these are many others which have considerable influence in the production of the results in question. It is known that different places change nature and quality on account of their position, of their constitution, and of their climate. This is easily observe in visiting different places distinguished by these particular qual- ities. Behold, then, one cause of variation of animals and of vege- tables which live in these diverse localities; but that which is not sufficiently known, and even what is generally refused credit, is that each locality itself changes in time, exposure, climate, nature and quality, though so slowly in comparison with our lifetimes that we attribute to it perfect stability. Now, in one and the other case, these changed localities change correspondingly the relations to living bodies which inhabit them, bringing to bear new influences on them, It is known that when there are extremes in these changes there are gradations which are intermediate, and which fill the interval. Consequently there are shades of difference, which distinguish what we call species. It is therefore evident that the entire surface of the globe shows, in its nature and in the situation of the materials which occupy different localities, a diversity of circumstances which is everywhere in relation with that of the forms and of the parts of animals, independent of peculiar diver- Influence of circumstances on the Actions of Animals. 967 sity which necessarily results from the progress of the composition of the organization in each animal. In every place where animals have been able to live, the circum- stances which have established there an order of things which has continued for a long time the same, and change is there really so slow that man has not been able to observe it directly. He is obliged to consult records, and monuments, and to recognize that in each one of these localities the order of things which he finds there has not always been the same, and thus to infer that it will still change. The races of animals which live in any of these places must preserve their habits for a long time, hence to us the apparent constancy of races which we call species—constancy which has given us the idea that these races are therefore as ancient as nature, But at different points on the surface of the globe which are hab- itable, the nature and situation of the localities and the climates constitute for animals, as for vegetables, different circumstances in all kinds of degrees. Animals which inhabit these different local- ities must then necessarily become different from each other, not only by reason of the state of growth of the organization in each case, but besides by reason of habits which individuals of each race are forced to adopt. Therefore, in a measure, in traveling over great portions of the surface of the earth, the observing naturalist sees circumstances change in a gradual manner ; he perceives constantly also that the species change proportionally in their characters. Now, the true order of things, which is the question to consider in all this, consists in recognizing,— Ist. That every change, of any importance, in the circumstances in which each race of animals exists, continually maintained, effects a real change in their necessities. 2d. That all change in the wants of animals necessitates for them new actions, in order to satisfy new wants, and consequently other habits. 3d. That every new want necessitating new actions to satisfy it, requires from the animal which experiences it, more frequent. employment of some of its parts of which it made less use before. Thereby are developed and enlarged considerably the new parts Which the wants have insensibly created in it by the efforts of its 968 Influence of circumstances on the Actions of Animals. “interior sentiment.” This is the question, as I will presently prove by known facts. To arrive at a knowledge of the true causes of so many diverse forms and so many different habits, of which known animals offer us examples, it is necessary to consider that the infinitely diversified circumstances, but slowly changing, which the animals of each race are continually encountering, produce for each of them new wants and necessarily changes in their habits, Now this incontestable truth once acknowledged, it will be easy to perceive how these new wants could be satisfied, and these new habits assumed, if we give some attention to the two following laws of nature, which observation has always proved to be constant :— First Law.—In every animal which has not passed the time of its development the frequent and sustained employment of an organ — gradually strengthens it, developes and enlarges it, and gives it power proportional to the duration of its use; whilst the constant disuse of a like organ weakens it, insensibly deteriorates it, pro- gressively reduces its functions, and finally causes it to disappear. Second Law.—All that nature acquires or loses in individuals by the influence of circumstances to which the race has been exposed for a long time, and in consequence by the influence of the predom- inate employment of such organ, or by the influence of disuse of such part, she preserves by generation, among new individuals which spring from it, providing the acquired changes be common to both sexes, or to those which have produced new individuals. These are, then, two constant truths which cannot be miscon- strued, except by those who have never observed or followed nature in her operations, or by those who entertain an error which I will combat. Naturalists having remarked that the forms of the parts of animals are always perfectly in harmony with the use of those parts, have thought that the forms and the conditions of the parts had caused their employment. Now this is an error, for it is easy tO demonstrate by observation that on the contrary it is the wants and uses of the parts which have developed these same parts, that they are made to exist where they did not, and that consequently they have given place to the condition in which we observe them in every animal. For, had this not been so, it would be necessary that nature Influence of circumstances on the Actions of Animals. 969 should have created for the parts of the animal as many forms as the diversity of the circumstances in which they had to live would have required, and that these forms as these circumstances should never have varied. This is certainly not the order of things which exists, and if it were really such we would not have the race-horses of the form of those in England. We would not have great draught-horses, so heavy and so different from the former. For had not nature herself produced the like, we would not have, for the same reason, lapdogs with slender limbs, greyhounds so agile in running, water-dogs, ete. We would not have poultry without tails, peacocks, pigeons, etc.; finally we would not be able to culti- vate wild plants, as we please, in the rich and fertile soil of our gardens, without fearing to see them change by long culture. For along time there has been in this respect a sentiment which has established the following saying, which has passed into a proverb, which all the world knows, that “habits form a second nature.” Surely if the habits and the nature of each animal never varied, the proverb would have been false, and would not have been used for the cases to which it had been applied. If people considered seriously all that I have just shown, they would know that I was well grounded in reasons when, in my work entitled “Recherches sur les corps vivans,” p. 50, I estab- lished the following proposition: “It is not the organ, that is to say, the nature and form of the parts of the body of an animal which have given origin to its habits and peculiar functions, but it is, on the contrary, its habits, its manner of life and the circum- stances in which individuals from which it came, found themselves, which have after a time constituted the form of its body, the num- ber and character of its organs, and finally the functions which it possesses. Let us weigh well this proposition, and give to it all the attention which nature and the condition of things continually gives us opportunity, Then its importance and its truth will become perfectly clear. Time and favorable circumstances being, as I have already said, the two principal means which nature employs in giving existence to all her productions, it is evident that time has no limit for her, and in consequence she has it always at her disposal. Concerning these circumstances, which she requires, and which she still uses 970 Influence of circumstances on the Actions of Animals. every day, to change all that which she continues to produce, they are in many ways inexhaustible to her. The principal proceed from the influence of climates, from that of diverse temperatures of atmosphere, and of all the surrounding media; that of the diversity of places, and of their situation; that of habits, of the . most ordinary movements, of the most frequent actions; finally, of that of the means of self-preservation, of manner of life, of defence, of multiplication, ete. Now, by continuance of these diverse influ- ences the faculties become expanded and strengthened by use, become diversified by new habits long maintained, and insensibly the conformation, consistence, in a word, the nature and condition of parts, also that of organs, participate in all these influences, maintaining and propagating themselves by generation. These truths, which are only the result of the two natural laws expounded above, are in all-cases strictly confirmed by facts ; they indicate clearly the progress of nature in the diversity of her pro- ductions. But in place of contenting ourselves with generalities which may be considered as hypothetical, let us examine strictly the facts, and consider, in animals, the result of the use or disuse of their organs upon these organs themselves. According to the habits which each race has been forced to contract, I will prove that the constant lack of exercise, as regards an organ, diminishes at first its functions, gradually impoverishes it, and in the end makes it disappear, or annihilates it; so this disuse perpetuates itself for a long time thereafter in successive generations of animals of the same race. Afterwards I will show that, on the contrary, the habitual exercise of an organ in any animal which has not experienced a diminution of its functions, not only perfects and increases its functions, but otherwise makes it acquire the develop- ment and dimensions which insensibly change it, so that after a time it renders it different from the corresponding organ of another animal which exercises it much less. : The disuse of an organ having resulted in the habits which it has assumed, gradually impoverishes the organ, and finally makes it disappear, or obliterates it. As such a proposition could be admitted only on proof, and not on simple declaration, we will attempt to make it evident by the citation of known facts which constitutes its basis. Influence of circumstances on the Actions of Animals. 971 Vertebrate animals, of which the plan of organization is nearly the same, although they show much diversity in their parts, have, usually, their jaws armed with teeth. Nevertheless those among them which circumstances have given the habit of swallowing their food without previous mastication have been found to display a repressed development of these parts—that these teeth have even remained hidden between the osseous plates of the jaws without being able to appear, or all traces of them have entirely disap- peared. Among whales, which people have believed completely deprived of teeth, M. Geoffroy has found them hidden in the jaws of the foetus. This professor has also found in birds the groove where teeth should have been placed, but nothing more has been seen, In the class Mammalia, which embraces the most perfect animals, and principally those of which the plan of organization of the vertebr is most completely executed, not only the whale has no teeth for its use, but one finds also in the same condition the ant-eater (Myrmecophaga), in which the habit of not masticating its food has been introduced and preserved for a long time in its race Eyes in the head is the rule for a great number of diverse animals, and are essential to the plan of the organization of vertebrates. Nevertheless the mole, which by its habits has very little occasion to see, has only very small eyes, and which scarcely show, because it exercises this organ very little. “ The Spalax d’Olivier ” (Voyage en Egypt et en Persia, II., pl. 82, f. 2), which lives under ground like a mole, and which is probably less exposed to the light of day, and has totally lost the function of sight, shows scarcely the rudiments of the organ which is its seat, and these vestiges are entirely hidden under the skin and under whatever other parts which cover it, which allow no access ot light. The Proteus, an aquatic reptile, cousin of the salamander, by all accounts lives in deep and obscure caverns, which are under ground, has, like the Spalax, only the traces of the organ of sight, which are covered and hidden in the same manner. Behold one decisive consideration relative to the question which I now discuss, Light does not penetrate everywhere, consequently animals which live habitually in those places where it does not come, lack occasion to exercise the organ of sight, if nature has provided them with it, Now, animals which partake in a ‘plan of organization 972 Glacial Drift of the Basin of Iowa. in which eyes necessarily enter, must have originally had them. And, since one finds among them species which are deprived of these organs, and which have only traces, hidden and covered, it becomes evident that the impoverishment and even the disappear- ance of the organ in question is the result of constant disuse.

THE region under consideration may include Floyd county, and portions of Cerro Gordo, Worth, Mitchell, Chickasaw, Bre- mer, Butler, and Black Hawk counties. The general topography of this region is that of a gently undulating prairie country, with often a more or less broken surface along the course of the streams. Portions of Worth, Chickasaw and Bremer counties are low and rather wet, while that of other portions of the area are dryer and more rolling. The western portion of this region is drained mainly by Flood and Lime creeks and the Shellrock river, while the eastern portion is drained by the Cedar and Wapsipinecan rivers and their affluents. All the streams of the area have a general northwest and southeast trend; their initial direction having been predeter- mined by the general dip of the subjacent rock strata. The Shellrock and Lime creeks have, for the most part, in their course through this region, eroded their channels through the drift, and into the underlying Devonian strata to a depth varying from five to seventy feet. The Cedar has cut through the drift, and sunk into the underlying rocks to a depth of from ten feet to overone hundred feet. The Wapsipinecan river and Flood creek flow through this country mostly upon the drift formation. The valleys Glacial Drift of the Basin of Iowa. 973 of the streams of this area are usually broad, with one side more or less well defined, while the opposite side gradually emerges into the adjoining upland. By far the greater portion of the surface of the area is occupied by the drift formation, which varies much in thick- ness at different localities. The difference seems to be par- tially due to original deposition, and partially to subsequent erosion. A line drawn from Waterloo, in Black Hawk county, in a north- west direction to Mason City, in Cerro Gordo county, and another line drawn from Waterloo to Osage, in Mitchell county, would include within their boundary the area of the thinnest drift of the region, and, indeed, of Iowa. In all parts of this attenuated drift area, the underlying rock strata is exposed at the surface in very numerous places. Present evidence seems to indicate that the superficial geo- logical formation of this entire region shows two main Glacia epochs, each of which is characterized by several subdivisions. , As belonging to the earlier Glacial epoch, there are recognized two drift sheets. Between these occur, at numerous points in the area, and other portions of the State, vegetal accumulations, indi- cating a non-glacial interval. This horizon is usually referred to as the “Old Forest Bed.” The material of the lower and upper drift sheets is (so far as observed) essentially the same, being com- posed for the most part of a heavy, dark blue clay, containing a greater or less number of transported deangulated erratics and pe bles, numbers of them being in a partially decomposed condition. At some points the clay of these beds is distinctly stratified, and as readily separated into layers as ordinary limestone. The vegetal accumulation which occupies a horizon between these drift sheets is composed of coniferous wood, branches and twigs, which is very often associated with ancient peat, and more or less mixed with the drift. In digging wells in this division, natural gas is often obtained,! this originating from the organic accumulation. Gathering evidence seems to demonstrate that the vegetal accu- mulation of this region, as well as that of some other places in the State, are referable to a single horizon. t In an article on “The Geology of Johnson county, Iowa,” which appeared in the May number of this Journal for 1888, mention was made, by the writer, of wells of this character in Linn county, Iowa. 974 Glacial Drift of the Basin of Iowa. As belonging to the later Glacial epoch, we recognize three divi- sions: the Upland, or (for the most part) unstratified drift ; Valley, or stratified drift; and Loess. The Upland drift constitutes by far the greater bulk of the superficial covering of the region. Its material is mainly true till, with local deposits or pockets of coarse gravel and sand, which is sometimes slightly cemented together by calcareous cement, and large numbers of transported erratics. There also occur local deposits of stiff red clay; for example, near Floyd, Nora Springs, and Rockford, in Floyd county. These deposits of clay are usually quite free from erratics, gravel or sand, has a soapy feel, and becomes very hard upon short expo- sure to the-atmosphere. The gravel deposits of this division are not restricted to any definite horizon, but are irregularly distributed through it. The material is usually well rounded pebbles of several varieties of greenstone, quartz (much of it probably of Cretaceous ori- gin), granite, Devonian limestone, jasper, etc. There also some- times occur specimens of coal, native copper and iron,! as well as * Devonian and Trenton fossils, Juarge numbers of deangulated granite and greenstone boulders, and more rarely those of quartz, are seen distributed over the surface and mixed with the till. The boulders vary in weight from two pounds to ten or twenty tons; of the latter, fine examples are observed near Portland, Osage, Nashua, and other places. i n some parts of the area, angular fragments of Cretaceous conglomerate are not uncommon in the drift. This material was probably derived, at least in part, from the southwest por- tion of Floyd county, where rocks of this age are known to occur in place.? The material of this division is usually unstratified, but at times it is observed to be obliquely and discordantly stratified at high points, distant from waterways. The region of most numerous erratics is that of the eastern portion of the area. A strip of country from one-half to four miles in width is occupied by great numbers of boulders, mostly of granite and green- 1 The occurrence of these ores, ete., in the drift of this region, was noted by the writer in a paper on “The Glacial Flow in Iowa,” which appeared in the August number of this Journal for 1887. ? A description of this rock has been given by us in a paper oD “A Description of the Rockford Shales of Iowa,” which appears in Vol. VI. of the Proceedings of the Davenport Academy of Science. Glacial Drift of the Basin of Iowa. 975 stone, This boulder line has been traced by us from a point about one mile northeast from Charles City, in Floyd county, to a little east of Waterloo, a distance of about fifty miles. Below this point we have not traced it; neither have personal observations of it been made beyond Charles City. It has been reported to me, however, that from Charles City the boulder line extends in an easterly direc- tion to a point near Fort Atkinson, in Winneshiek county, and there turns and pursues a more northerly course. From Charles City this boulder line takes a general southeast course, passing about two miles east of Nashua, in Chickasaw county, where it attains its greatest observed width, four miles. From this point it assumes a somewhat more easterly direction, and gradually diminishes in width. At a point midway between Richland Centre and Frederica, it again turns and pursues a more southerly course to Waterloo; the direction corresponding in the main with the general trend of the Wapsipinecan and Cedar rivers. In some localities, for example, Richland Centre, Frederica, ete., breaks in this line occur, from one-fourth to one-half mile in extent, where the erratics are rela- tively rare, but which soon appear again in strong force, An interesting and instructive feature of these boulders is, that they are all (so far as noticed) deangulated, smooth, and very hard, while large numbers of them are flattened and striated on one side by gla- cial action. This feature is shared in to no such extent by the erratics of other portions of the area. The second recognized divi- sion of the later Glacial epoch is the Valley, or stratified drift. Of the river valleys of this region, only one is known to contain true Valley drift; and this the valley of the Shellrock. Although at different places along the course of some of the streams, local deposits of more or less distinctly stratified drift occur, still, as a rule, this feature is no more pronounced than at some points in the Upland drift. The Shelirock heads near Lake Albert Lea, Minnesota, and flows into this sheet of water at its upper extremity, and makes its exit at its lower of southern extremity. This sheet of water occupies a depression in the Inter-lobular moraine which enters Iowa. The Shellrock flows upon this heterogeneous drift accumulation for a distance of ten miles, and ' Owing to the lack of other rock here for building purposes, the boulders are extensively used for underpinning, well and cellar walls, bridge piers, etc., for which they answer a most excellent purpose. 976 Glacial Drift of the Basin of Iowa. in reality does not reach the subjacent rock strata (except at two or three points) until Plymouth, in Cerro Gordo county, Iowa, isreached. From this point to its confluence with the Cedar, fifty-seven miles below, it has eroded its channel down through the drift formation, and flows upon the underlying Devonian strata. Stretching away from the morainic border, and partially filling the valley of the Shellrock, is a train of Valley drift, which extends to the confluence of this stream with the Cedar, seventy-two miles below. This morainic border lies upon rolling country, and there leads away from it, in portions of Cerro Gordo and Worth counties, valleys or trough-shaped depressions of notable size, which we should naturally expect would have drawn very considerable drainage floods from the margin of the ice. The material of this formation is usually well rounded, coarse and fine gravel and silicious sand, not essentially differing from the Upland drift gravel, except that it contains a very much larger percent- Pre. i: Ee yarns Shale: ye at ARA, se 22 ae mas tts ae age Dee ty, - et 2 Reon ENTS St te IER Y A gs era ryrie FRS Ea age of silicious sand, and does not usually contain any percepti- ble admixture of ey The material (except the very coarse portion) is everywhere obliquely and E stratified.

The upper bed isa fine silt-like soil, mixed with coarse drift gravel, due in part to secondary accumulation arising from wash from a slight adjoining slope. The talus of sand at the base conceals several subordinate beds. Fig. 2, Fig. 2 represents a section of Valley drift near Nora Springs, illus- trating oblique stratification. The material is well rounded gravel and ii PEN R- pP sand. The upper bed isa black I g - g small drift pebbles. The second bed is a yellow clayey soil, with some fine gravel in the lower portion.! The next succeeding bed is partially stratified gravel and sand. The wave-like parts of Figure 1 cor- respond to succeeding plunges in the rapidly flowing waters, and indicates a much more turbulent condition of the water than when the material of Figure 2 was deposited. At Clarksville, in Butler county, and other places, the Valley drift is seen to be obliquely stratified, the same as near Nora Springs. The gravel of this division at different points has been more or less solidified by calcareous cement. An interesting feature of this formation is that very often a large percentage of the finer material occupies the lowest position. while the coarser material often occu- pies the higher position. Fine examples of terraces are observed along the streams of this region; for example, on the west side of the Cedar, a few miles above Waverly; on the west side of the Shellrock, two ' These beds well illustrate the condition of the first few feet of the oe accumulation of nearly all parts of the area under considera- 978 Glacial Drift of the Basin of Iowa. and one-half miles northwest from Rockford; on the east and west sides of Linn creek, one and one-half miles west of Rockford, and other places. These terraces appear to have been formed by the contracting and deepening of the channels of these streams by their own waters. The last recognized division of the later Glacial epoch is the Loess formation. This formation is represented by only a few limited outliers at different points along the course of the Cedar river. On the west side of the Cedar, at Mitchell, in Mitchell county, is a local deposit of very fine and homogeneous, typical yellow loess, having a thickness of twelve feet. This rests directly upon a layer (from four to six inches in thickness) of clean rounded and angular drift pebbles, and the pebbles in turn rest (in places) upon a very dark, ferruginous layer of rock, which lays upon broken-up Devonian limestone below. In the lower portion of the exposure of loess, one or two large shells was found, which were, however, in a too imperfect state of preservation for satisfactory determination. On the east side of the Cedar, one mile above Floyd, another outlier of this forma- tion occurs. The loess at this place is like that observed at Mitchell, except that it contains small quantities of silicious sand in places, and in places has a very slight blueish-gray shade. The greatest observed thickness of this exposure was, by estimate, twenty-one feet. No drift was seen to intervene between the loess and the coarse-grained calcareo-silicious sandstone below. The surface of the rock at this place rises to a height of over one hundred feet above the water in the Cedar. The locality where this formation is next observed is on the same stream, at Waverley, about thirty-two miles below Floyd. The loess here (so far as ascertained) is light yellow, fine-grained and homogeneous, but contains at one point a very large amount of dark, grayish-brown silicious sand.

HISTORY OF GARDEN VEGETABLES. BY E. LEWIS STURTEVANT, M.D. (Continned from page 808.) Kohl-rabi. Brassica oleracea caulo-rapa, DC. I FIND no certain identification of this race in the ancient writ- ings. The bunidia of Pliny! seems rather to be the ruta baga, as he says it is between a radish and a rape. The goggulis of Theo- phrastus* and Galen? seems also to be the rutabaga, for Galen says the root contained within the earth is hard, unless cooked. In 1558 Matthiolus‘ speaks of the kohl-rabi as having lately came into Germany from Italy. Between 1573 and 1575 Rauwolf® saw it in the gardens of Tripoli and Aleppo. Lobel® in 1570, Camerarius? in 1586, Dalechamp ê in 1587, and other of the older botanists, all figure or describe it as under European culture. This plant, in the view of some writers, is a cross between the cabbage and the rape, and many of the names applied to it convey this idea. This view 1s probably a mistaken one, as the plant in its sportings under cul- ture tends to the form of the marrow cabbage, from which it is probably a derivation. In 1884, in two plants in pots in the ‘Pliny. Lib. z2. 6 2 * Gronovius. Orient., 81. Pena and Lobel. Adv., 1570, 92. ; Camerarius. Epit., 1586, 251. * Hist. Gen. Lugd., 1587, 522. 980 History of Garden Vegetables. green-house, I had good kohl-rabi bulbs, and one of these extended itself until it became a marrow cabbage, and when planted out in the spring attained its growth as a marrow cabbage. This idea of its origin finds countenance in the figures of the older botanists ; thus Camerarius, in 1586, figures a plant as a kohl rabi which in all essential points resembles a marrow cabbage, being tapering from a small stem into along kohl rabi, with a flat top like the marrow cabbage. The figures given by Lobel,' in 1591, Dodo- neus,” in 1616, and Bodsus,’ in 1644, when compared with Came- rarius’ figure, suggest the marrow cabbage. A long highly improved form, not now under culture, is figured by Gerarde,‘ in 1597, J. Bauhin,’ in 1651, and Chabreeus,® in 1677, and the modern form is given by Gerarde, and by Matthiolus’? in 1598. A very unim- proved form, out of harmony with the other figures, is given by Dalechamp,’ in 1587, and Castor Durante,’ in 1617. This synonymy can be tabulated in order as below :— 1. Caulorapum.

These excerpts indicate a southern origin for this vegetable, and the marrow cabbages are very sensitive to cold. The more highly improved forms, as figured in our synonymy, are in authors of northern or central Europe, while the unimproved forms are given by more southern writers. This indicates that the present kohl rabi received its development in northern countries. The varieties now grown are the white and purple, in early and late forms, the curled leaf, or Neapolitan, and the artichoke-leaved. One, at least, was in American gardens as early as 1806, and the rest appear before 1863. The nomenclature of this plant is deserving of attention, from the presence of foreign words, for which its history seems to afford but little justification. The kohl-rabi, Turnip-rooted cabbage, Arabian, cole rape, cole turnip, Cape cabbage, or Hungarian turnip, is called in France choua-raves, chow de Siam, boule de Siam; in Germany, oberkohl- rabi; in Flanders, raapkool; in Holland, koolraapen boven den grond; in Denmark, overjordisk kahlrabi, kwndekaal; in Italy, cavolo rapa, torsi; in Spain, col rabanho ; in Portugal, couve rabano, couve de Siam ;? in Norway, overjords-kaalrabi ;3 in India, ole kole, or gool jur ka kuhun.* Lavender. Lavandula vera DC. Lavender is sometimes grown for the use of the leaves as a con- diment, but more often for the flowers, which find use in perfum- ery; but we have never heard of its being grown on a large scale in the United States, although it was in garden culture in 1806. Its present growing is doubtless very insignificant. There is no satisfactory identification of lavender in the writings of the ancients, although it seems to have been well known to the botanists of the sixteenth century, and the use of the perfume was Indicated as early as the fourteenth century, and as a medicine even in the twelfth century. Its seed was in English seedsmen’s lists of 1726,’ for garden culture. ' Townsend, seedsman, 1726, 28. 7 Dodonæus. Gard. Dict., 1831, i., 228. ? Vilmorin. Les Pl. Pot., 1883, 139. * Schubeler.

Lavender is called in France lavande, aspic, lavande femelle ; in Germany, lavendel, spike; in Flanders, lavendel; in Denmark, lavendel ; in Italy, lavanda ; in Spain, espliego.? Lavandula spica L., a more southern species, is confounded with the above in cultivation, and is also cultivated on a large scale for purposes of distillation. Mawe, in 1778, named four varieties, the narrow-leaved with blue flowers, the narrow-leaved with white flowers, the broad-leaved and the Dwarf. Leek. Allium porrum L. This vegetable was the prasun of the ancient Greeks, the porrwm of the Romans, who distinguished two kinds, the capitatum, or leek, and the sectilis, or chives, perhaps, although Columella,’ Pliny* and Palladius* indicate these as forms of the same plant brought about through difference of culture, the chive-like form being produced by thick planting. They seem to have been very popular at Rome. In Europe the leek was generally known throughout the middle ages, and in the earlier botanies some of the figures of the leek represent the two kinds of planting alluded to by the Roman writers. In England, in 1726, Townsend? says that “leeks are mightily used in the kitchen for broths and sauces.” When they reached America I do not find recorded, but prior to 1775 they were grown at Mobile, Ala., and were cultivated by the Choctaw Indians.° : The leek may vary considerably by culture, and often attains quite a large size; one with the blanched portion a foot long and nine inches in circumference, and the leaf fifteen inches in breadth and three feet in length, has been recorded.’ Vilmorin® described eight varieties in 1883, but some of these are scarcely distinct. The leek, or porret, is called in France poireau, poiree, poirette, porreau; in Flanders and Holland, prei; in Germany, lauch, por- 1 Vilmorin. Les Pl. Pot., 1883, 318. 2 Columella.

Lentil. Ervum lens L. The cultivation of the Lentil is very ancient, as it has been found in the Egyptian tombs of the twelfth dynasty, or 2,200 to 2,400 B.C.” It has also been found in the lacustrine debris of Switzerland dating from the age of bronze.* Its culture was well known to the ancient Greeks and Romans, and has been continued through the middle ages to the present time. Bauhin,’ in 1623, names a large and a small sort, the seed reddish, pale yellow, white, ` tawny and black, and Vilmorin,” in 1883, describes four varieties for garden culture. Its seed is used in soups and stews, and the culture is of more importance in the warmer regions. Lentils are recorded by Burr," in 1863, for American use; but much of the seed found exposed for sale in groceries is imported.

In England, Chaucer, about 1340, uses the word in his prologue, “ well loved he garlic, onions and lettics,” and it is likewise mentioned by Turner,” in 1538, who spells the word Jettuse.

In the report of the New York Agricultural Experiment Station for 1885, eighty-seven varieties are fully described with 585 names or synonyms. Vilmorin describes, in. 1883, one hundred and thirteen kinds as distinct. The number of varieties named by various writers at various times are as follows: For France, in 'McIntosh.

THE WESTERN SOCIETY OF NATURALISTS! BY S. A. FORBES. ‘yen first presidential address of a new society may well have for its subject the society itself; and the first duty of those respunsible for such a society is to show its right to exist. There is only so much social power available for social purposes; why should we string a new belt to the already heavily burdened shaft, and tax the groaning engine with the movement of a new machine? Shall we interrupt and weaken the action of any existing agencies by this additional draft on the common stock of energy? or may we believe, on the contrary, that the final effeet of our organization will be to increase the energy and activity of the whole apparatus ; that it will react, in time, to supply power greater than that which it abstracts? In short, what are the objects and purposed uses of this Society of Western Naturalists? first, as to its own members ; and second, as to society at large. These questions I shall endeavor to answer—not authoritatively—for only the Society can spea with authority for itself—but by way of interpretation and personal suggestion, hoping at least to raise questions concerning our scope, intention, and relations, which you may answer finally according to the common wish and judgment. It seems proper, first, to say that in asking these questions, and in my attempts to answer them, I have in mind the present time, place, and conditions ; that I shall not treat of the work which this Society might and should perform if it were established in Europe or on the Atlantic seaboard, or if it were working in the twentieth century, but I shall inquire what are the ways in which we can most and best advance the study of our subjects in the present ume and the immediate future, taking as our starting point the state of knowledge, the conditions of progress, and the special problems presenting themselves now in the northern half of the MississipP! valley. ; And first, I remark, in phrase now temporarily classic, that “it is a condition and not a theory that confronts us.” In the course 1 Presidential address delivered at Champaign, Ill., October 24, 1888. Western Society of Naturalists. 989 ot the development of science in this region, the easy things have in great part been done. The glittering sands have been largely passed through the cradle of the pioneer miner; the easily worked ores have been more or less thoroughly extracted, and we are fast approaching, if we have not already reached, the period when accumulated capital, powerful and complicated machinery, and the expert skill of the mining. engineer are indispensable to the further development of our natural wealth, When a morning walk along the banks of the Wabash would give a Say new objects enough to keep him happily busy for weeks; when the moderately careful search of a single orchard or garden would yield to Fitch or Walsh, or the boyish Riley, material enough for an elaborate report; when the virgin soil of natural science only needed to be tickled with a hoe to laugh with a harvest, the question of methods and apparatus was one of quite subordinate importance. Little method and less machinery were needed to make a man useful and even eminent. And as for the educational problems with which we now have to deal, they gave the least imaginable concern, because they were practically non-existent. Until the movement for an industrial education based on science began, like a great ground swell, to heave the quiet sur- face, and until the tidal wave of popular interest and personal enthusiasm, set in motion by the elder Agassiz at Cambridge, swept across the West, the question of methods of instruction in natural history in school or college stood scarcely higher in the general estimation than that of the study of the language of the inhabit- ants of Mars. No one troubled himself about either. But since then, progress has been positive and really rapid, as those can best believe who have felt the full lift of the surge—has come with a speed accelerated, in fact, by the coincidence of three great move- ments, First, the onward movement of the natural sciences themselves— a growth which is the continual astonishment of every intelligent observer, and the despair of all but the ablest and most active students, Second, the movement of growth and development in this nterior region, relatively new, and newest of all in matters of Science—this again a movement phenomenal in the history of the world. 990 Western Society of Naturalists. And third, the progress resulting from the substitution of a younger and more highly educated working generation for an older one largely without special training. From all this has come a recent change of status and surround- ings, a modification of standards, a shifting of purposes and responsibilities, an accession of ideas, and a multiplication of duties, such as to compel us to consider the situation anew, and to urgently require a reorganization, along new lines, of whatever strength we can muster. In brief, the old machinery of scientific organization and development here in the West is much of it obsolete and in- active, and, taken as a whole, it is insufficient for the present day. The field of operation proposed by our Society—that of the improve- ment of methods of work, study, and instruction, is newly opened up to us by the rapid multiplication and complication of our sub- jects. The work we shall do is largely a new work, laid upon us as a condition of further symmetrical growth ; and its performance is a duty which the promoters and curators of science and education in this region can avoid only at their own peril, and to the injury of the interests for which they have made themselves responsible. we look now to the benefits which we as individuals may hope to derive from our meetings, I count as most important some of those which are perhaps least obvious. We are distinguished especially as a Society by an attention to methods rather than to results. That each worker should be deeply interested in whatever improvements of method are brought to light in his own field goes without saying, for in scientific research the method is, next to the man, the most important thing; the quality of the result depends on the choice of it, and the quantity upon that ready familiarity with it which makes every stroke tell to the best advantage ; but if this were all, we should find ourselves splitting up into little sections of specialists, each indifferent to the other; or resolving ourselves, as an alternative, into a mut toleration society, each group bearing patiently with the discussions of the others, that it might have the floor itself in turn. In fact, however, the methods of the different sciences are much more closely related than their results, and I am much mistaken if I, as a zo0l0- gist, shall not learn at least as much from the contributions to scientific method made by the botanists and geologists as from those Western Society of Naturalists. 991 in my own field. I may care little for the classification of the Ustilagineæ, but the methods by which that classification were worked out may be of the greatest use to me in entomology. I had occasion at one time to study minutely a purely biological problem—that of the food preferences of certain families of beetles, about which too little was known, but found that I could do nothing with it except by the methods of the insect anatomist, on the one hand, and of the microscopist on the other. I need to know about the contagious diseases of insects, as a matter of practicable and biological entomology, but find myself powerless to investigate them until I become expert in the methods of the baceriologist and the cryptogamist generally, and until I can make the nicest of histological preparations. I would like to learn the life histories of some phytophagous insects, but by the time I have worked them out I shall have made a close practical acquaintance with several of the methods of botany and horticulture. A new piece of appa- ratus in the hands of the mineralogist will suggest to the botanist a device solving a difficulty which has long blocked his way in some tempting line of investigation. I wish now that some chemist would tell me how to distinguish spherical pigment granules, by chemical means, from micrococci. That item of chemical method would break down a barrier against which I have bumped my head in vain for a year. And if this is so with methods of research, much more is it true of methods of instruction. The geologist has to do primarily with rocks and fossils, the botanist with plants, and the zoologist with animals; but teachers of whatever subject all have to do primarily and chiefly with the human mind and the training of it, and teachers of whatever natural science have special ends in view with respect to the training of mind not very widely different. If I shall be profited by knowing how the geologist does his work, much more shall I be pleased to learn how he leads his classes; and it is to be hoped that the discussions of teaching methods to which our meet- ings should give rise will result finally in the common acknowedg- ment and established use by all of us of certain principles and methods, such that our work may have a uniform character, and its results a definite value, not wholly dependent on the point of view and the personal idiosyncrasy of the instructor. . 992 Western Society of Naturalists. While our community of interests, this overlapping and inter- mingling of methods, brings us into closer fellowship than if this were an academy of sciences merely, so the motive that induces us must give our meetings an air of cordiality, of mutual gratitude, and good will. He who reads me a paper embodying results of research—the finished product of his work—may do it for my benefit, or possibly for his own—it sometimes takes evidence to determine which; but he who takes me into his shop, and shows me just how and with what he works, exposes to me the skilled methods which have yielded the results I admire and emulate, does that for me, there is no doubt about it. We may be sure that the contributors to our programmes will be governed by a generous wish to share with each other the most precious items of their knowledge, those on which they especially depend for their own professional success. ‘hen we shall profit greatly, beyond a doubt, by the knowledge gained of the state and progress of science and education in our midst, as we hold our successive meetings in the various centres of education and research throughout our territory ; and thus we shall learn what is the best thing which we as a Society can do for science in this region, and in each part of this region, from year to year, and shall be prepared always to welcome intelligently, and readily - to assimilate the new energies penetrating to our midst—avoiding, on the one hand, that attitude of selfish and obstinate conservatism, which, acting on the unprincipled motto, “After us the deluge,” would sweep back the future with its burden of progress; and, on the other hand, rapidly, but genially, toning down the crude and intolerant egotism of the occasional brand new man, who thinks to himself, “ Before me chaos.” And so we shall hold, I hope, to — the golden mean of vigorous and rapid, but continuous and har- monious, growth. But the scientist is also a citizen, and all the more a citizen the more a scientist he is, if he knows his own interest and duty. His social responsibilities, like those of all other men, increase with hie capacity, with his possible importance as a factor in the social scheme; and he has a special social interest due to the fact that the higher the grade of his work, the more important to him, the mof? nearly indispensable, indeed, is a high grade of social organization Western Society of Naturalists. 993 about him—a fine and intelligent spirit; for without these, the institutions, the enterprises, essential to his success can neither be established nor maintained. Each scientific society, if it is to live and thrive, must serve as a centre of upheaval for the community at large. If we unite and firmly bind ourselves in a society of restricted numbers, and with somewhat limited conditions of admis- sion, this is not done with any unworthy purpose of discriminating in our own favor, or of confining to our membership the benefits of our association, but to give unity and distinctive character to our influence, that it may reach farther and go deeper than if the energy of our organization were to be chiefly spent in keeping our- selves alive, And so we may inquire, what is to be our outside influence? I think that we may reasonably expect, acting within the limits of our organization, and along the line of our special purposes, to have a stimulating and directive influence upon the science work of the educational institutions and associations of this region, upon the local scientific societies with which we are connected, and, through our meetings and papers, upon the more intelligent part of the - general public. While ours is not primarily an association of teachers, but of original workers in science, it so happens that most of us teach, and there is certainly no way in which we can advance science more effectively than by sending out classes of bright and ambitious pupils prepared for research. Discussions of the methods of this work must consequently always be in order; and besides this internal work and influence, I believe that we should lay down, advocate, and defend a few general principles—bearing, for example, on the relations of instruction and investigation, on the main ends _ Of training in science, on the selection, arrangement, and co-ordina- tion of subjects in each division of the courses in which we are especially interested; on the amount, kind, and time of introduc- tion, of primary work in science preparatory to that of our higher institutions of learning, and the like. Preliminary, however, to any application of such principles to the actual situation in this region, we certainly and especially need to examine the situation itself, with respect to the institutions which we represent, to others not connected with us by membership of their instructors, and to the preparatory and high schools generally. I would greatly like 994 Western Society of Naturalists. to see a committee or committees raised which should report to us at our next meeting a well-digested exhibit of these matters. Nothing could be more useful to us, and nothing, I think, would bring our work more directly and favorably to the notice of our immediate public. And then, in the papers and discussions of our school and college associations, in our State and more local scientific societies and academies, we should bring to bear the ideas and principles established by discussion here, and so carry the work outward by concerted action, as by a movement in line. To our semi-scientific and scientific associates outside this body, we should, of course, carry whatever new thing of applicable value our meetings give us possession of, and thus enlarge the circle of the Society’s influence. In these and other ways I hope that we might do much to increase the number of intelligent local observers and earnest independent students—now far too few in this region— and thus help to create and sustain a scientific sentiment, in which the present and approaching generation certainly fall far short of that now going out of action. It is a suicidal blunder to dis- ` courage the amateur, to undervalue the mere collector of speci- mens and reporter of facts, to create the impression, either wilfully or unwittingly, that none but the very learned have anything to do with the promotion of science. We cannot hang the truncated apex of our pyramid to the stars, not even to those of the German heaven—and if we could, we should not, for, after all, science 1s for man, and not man for science. The general public, it might seem, can scarcely be interested—even the more intelligent part of it—in a conference of specialists respecting their methods of tech- nical work, and yet I think that this view is not altogether correct. Whoever cares for the results of scientific inquiry must usually be curious, at least, concerning the methods by which those often sur- prising results are reached—and frequently the method is by far the more interesting and the more easily understood. While much of our discussion of details would be tedious, and many fragmentary contributions incomprehensible, we might, I think, at least prepare at each meeting one or more evening programmes for the general public, setting forth fully and systematically several of the more remarkable and interesting processes of the biological laboratory and the geological office; the pure culture of bacteria, Western Society of Naturalists. 995 the methods of minute measurement, and those of microphotography, the preparation of serial sections and the like—all to be used, per- haps, as illustrations of the general method of science at large. For, after all, the method of science, if the general public only knew it, is of greater importance to them than its matter. The method of science is simply the swre method, and the simplest and most economical consistent with certainty. Any other is either wasteful or unsafe. To know, to appreciate, to command this method, is to control resources beside which the mere knowledge of facts has but little significance. It will be the most important public function of this Society to extend the knowledge and the use of the method of science, applied in the spirit of science, among the unscientific. The great mission of science is two-fold—to reveal the universe, and to rationalize the human mind. The first of these tasks, vast as it is, is still compara- tively easy, for it is wrought out directly by the scientist himself applying the methods and apparatus of research to the facts of nature; but the second is immeasurably more difficult, because it can only be accomplished by a sort of a beneficent contagion affect- ing the spontaneous activities of the individual mind; by the persuasive influence of example, and a perceived superiority of results. To improve every occasion to expose, to commend, and to illustrate the scientific method, to encourage its application, to lead in its use in the common affairs of life and society —in business, in politics, in ethics, in whatever affects the welfare of man as a social being, is a duty to our kind, the importance of whose performance we shall never perhaps see more eloquently illustrated than by the occurrences of the present moment, when some of the greatest Interests of one of the greatest nations of history are hanging on the decision of a purely scientific question by unscientific minds, worked upon by methods as little scientific as one can well imagine. It thus seems certain, finally, that our young Society cannot languish for want of a field appropriate and peculiar to itself, for lack of a varied, greatly needed, and highly important work, bene- ficial to its members and to the general community—a work which nothing else is now attempting, and which, if we do not do it, seems likely to remain undone. The quality of our membership, the number and spirit of those in attendance on this, our first 996 Sketches of the Cascade Mountains of Oregon. annual meeting, the valuable character of our programme, are all an earnest of growth and active labor. Let us all lend the promis- ing youngster our warmest wishes for a vigorous and useful career, and join in the cheer, long life, and a busy one, to the Western Society of Naturalists. SKETCHES OF THE CASCADE MOUNTAINS OF OREGON. BY E. D. COPE. To Cascade Mountains of Oregon are destined to be the favor- ite resort of tourists who love all that is most beautiful, im- pressive and wild in mountain scenery. Lying over one of the greatest of the fractures of the earth’s crust, they represent the remains of successive outflows of molten material at its source. The basis of the range is eruptive, and displays the irregularities of surface due to such origin within comparatively recent geological ages, and to the rapid erosion which naturally occurs in a humid climate. Thus gorges of great depth traverse its masses, and preci- pices of tremendous height bound many of its elevations. Beautiful lakes nestle in its depressions, and waterfalls leap from level to level on their way to the tributaries of the Columbia. All is clothed in sombre forest of conifers, of larger proportions or more elegant foliage than can be found in any other region. High above all these mountains tower at intervals along the range, the great snow-peaks which give the region its especial beauty. These are extinct volcanoes which raised themselves round vents which long remained open, and which poured out lava, scorie, pumice and ashes, after the great fissure was closed. The great lava outflow from the Cascade Mountain fissure is one of the most extensive the world has ever seen, and was one of the most destructive in its consequences. There were several distinct periods of outflow, two being especially distinguishable in the strati- graphy of central Oregon. Between the outflows from this and from lesser sources to the eastward, a country of eight hundred Sketches of the Cascade Mountains of Oregon. 997 miles in east and west extent, and one hundred and fifty miles from north to south, was covered with lava and other ejectamenta, ren- dering it uninhabitable by animal life. The volcanic materials are found for several hundred miles to the north, àt some points con- tinuously with the great tract I have mentioned. The exact connection with the latter remains to be ascertained ; but both were deposited at about the same geological period ; viz.: from some time in the Eocene to late in the Miocene ages. The area covered is not less than 1,600,000 square miles in extent, embracing all of central and southern Oregon and southern Idaho, and large tracts in Tacoma, Territory. As an offset to this terrible and unexampled desolation of one of the fairest parts of the earth’s surface, we have the great snow-peaks standing as silent and imperishable monu- menis of one of the most tremendous of the wars of the elements that the later earth has experienced. The grand tour of Oregon is commenced by crossing the gap in the Cascade range at Ashland, just north of the California border, and visiting the Klamath Lake on the eastern side of the water- shed. Turning northward, the tourist should visit the Crater Lake, twenty-five miles from Fort Klamath, and return. Then go north- ward again on the edge of the plateau that overlooks the valley of the Des Chutes River toward the west, from which the highest of the ranges of the Cascades rise, and may be seen in all their mag- nificence. Continuing on this road, now a stage route, the Dalles of the Columbia river are reached. Thence take the steamer down the river for Portland. The scenery of the long pass of the Colum- bia through the Cascade Mountains has been often praised, but never too highly. From Portland excellent means of transpor- tation south, up the Willamet valley, will return the traveller to Ashland again, and the grand tour is completed. A trip from Portland to the resorts on the coast-range must not be omitted, for from these can be seen, it is said, twenty of the snow-capped sum- mits of Oregon and Tacoma (Washington), on the one side, and the boundless waters of the Pacific Ocean on the other. - The traveller must make this journey in a private conveyance, if he can do so, excepting as to the Columbia River. He should commence at Sisson’s, at Mount Shasta, in northern California, Then he will see the mountains in all their changing moods at his 998 Shetches of the Cascade Mountains of Oregon. leisure. He will become personally acquainted with each of the great landmarks as he passes them one by one. First, Shasta of colossal dimensions. Then the perfectly regular Mount Pitt, which overlooks Lake Klamath. Then the Batchelor with blunt apex ; next Mount Cope, with its dome and its lower twin summit; and twenty miles to the north, the two peaks of Mount Condon joined at their bases, acute and inaccessible. At a longer interval follows Mount Jefferson, which rears its immense bell-shaped mass from a widely spreading base, to a height of 13,000 feet. Finally, near the Columbia, the perfect cone of Mount Hood lifts its head 14,000 feet and more to the skies. The form of all these peaks is essentially Andean. They are, like Popocatapetl, Cotopaxi, and Pichincha, of a general conical form, and thus quite different from the mountains of the Rocky range, or the Alps, which are mostly culminations of larger masses, or rise from plateaus, so that the visual effect of their elevation above the sea is largely lost. The case is quite different with ranges whose base is, like that of the Cascades, but little elevated above the sea. In the latter nearly the entire elevation is visible. The Cascades also, gathering the moisture from the ocean in a northern latitude, receive and display a greater deposit of snow than ranges of greater elevation in drier or more southern regions. (Plates XX and XXIT.)! Although there are many lovely lakes in the Cascade Mountains, none is so remarkable as Crater Lake. This is a body of water which occupies an extinct crater of large size. It is of an oval form and about eight miles by six in diameter. The walls which surround the water rise to a height varying from 900 to 3,000 feet, and they are so precipitous that their descent is practicable at very few points. At the time of my visit (in 1879) but one mode of access to the water was known to my guides. This I descended to the water’s edge. It is a very steep washed slope covered with loose stones and scoriz, among which the descent is much more easy than the ascent. To the south of the centre of the lake is an island which consists principally of a volcanic cone, with a distinct erater in its summit. This represents the latest centre of activity of the voleano. Its sides were covered with tall firs at the time of MY visit. The depth of the water is very great. Captain C. E. Dut- ton, of the present U. S. Geological Survey, informed me that he 1 The plates referred to will appear in the next number of the N aturalist- Sketches of the Cascade Mountains of Oregon. 999 obtained 1,900 feet as the greatest depth, and 1,500 as the average, in 1886. (Plate XXI.) At the time of my visit Colonel Whipple was in command at Fort Klamath. He carried out a projected visit to Crater Lake at this time and kindly gave me the opportunity to accompany him. As we left the Post we were greeted by the clamor of the beautiful white-headed woodpeckers (Picus albolarvatus Cassin) which nested in the tall pines near the officers’ quarters. We soon seven-mile creek, which abounds in the red-spotted trout of the Pacific coast, or the “ dolly-varden ” (Salvelinus malma), and com- menced the ascent. We followed the course of a mountain torrent which often disclosed in its precipitous banks the friable volcanic material of which the mountain is composed. Sand and ashes, with here and there strata of fragments of scoria and lava were princi- pally visible. The soil was evidently good, for it supported a luxuriant forest of trees and undergrowth. Prominent among the former are two beautiful firs, whose foliage is elegant but broadly contrasted in character and appearance. These are the Abiés nobilis, and the A. pattoniana. The foliage of the former is rigid, and the disposition of the terminal branches almost rectangular. The green is of a rather dark shade. The second species is, on the other hand, feathery in foliage and gracefully drooping in branches, and the green is paler. Above both these species towers the monarch of the north-west, the Douglass fir (Abiés doug/assii), the largest species of its genus, forming the bulk of the forest. But it yields in height to the occasional sugar pine, Pinus lambertiana, with its graceful candelabra-like branches and long cones, the tallest of pines and a fit mate for the Douglass fir. On our ascent we passed a herd of blacktail deer, which were browsing in security on an open slope of the creek banks. By evening we were encamped on a babbling run under the shade of towering firs. The whisky-jacks, Perisoreus canadensis, flitted from branch to branch, and descended to inspect our proceedings with their usual familiarity. Half jay and half titmouse, this bird makes a home of every camp, and tends no little to relieve the Sense of savage wildness by its pretty and confiding ways. By early morning we were at the summit. This was simply an open grassy expanse on the eastern edge of the awful chasm, 1000 Sketches of the Cascade Mountains of Oregon. surrounded by an irregular border of the forest. The day was clear, and everything could be seen in perfection. Far down on the water I descried a moving white speck, probably a trumpeter swan, as no smaller bird would have been visible at the distance. Across the gulf rose the two points of the mountain called by the hunters the “ Rabbit’s Ears;” and further to the north-west the aiguille, known as “ Cowhorn Peak.” The water of the lake glis- tened in the sun, oblivious to the awful scenes that had once ren- dered this place the pandemonium of the continent. I descended to the water’s edge, and examined carefully for traces of animal life. I found a very young larva of a salamander. More fully grown specimens have been since obtained by Lieutenant Carpenter, U. S. Army, and sent to the National Museum, which are probably the young of Amblystoma macrodactylum, the only salamander that has been found adult in that region. Then I found larve of Phrygan- eide and Ephemeride, and some minute crustacea, as Gammari and water-fleas. Among the rocks on and beside the slope, the “ little chief” hare, Lagomys princeps, crept in and out, uttering the while its peculiar plaintive ery. It is a rather tame animal, and appa- rently possessed of much curiosity, but it has always a fissure in the rock at hand into which it retreats if one approaches too near. The walls of the crater on the eastern side are made up of suc- cessive layers of lava, scoria, sand, ashes, pumice, ete., all repre- senting successive eruptions and parts of eruptions. The mass is in places friable, and is penetrated by the waters of the lake at differ- ent points, thus giving origin to springs and streams. At Fort Klamath the soil rests on a deep stratum of pumice. Some of the exposures show this to be broken up and water worn, but at other places it forms a continuous spongy mass. Ina stratum of this kind, just below the soil, were cut the four graves of the Modoc Indians, who were hung for the assassination of General Canby, the commissioner sent by the United States to treat with the tribe. These graves were cut out with right angles and borders by the simple use of a sharp spade. At the time of my visit all of them had been rifled, and the bodies taken away. I afterwards obtained the skeleton of one of them. It is characterized by 4 platycnemic tibia, and tritubercular second and third superior molars. Soon after this visit I left Fort Klamath for a geological explo- PLATE XIX.—View from Lake Klamath, looking north towards Crater Lake.

I found unexpected assistance in this exploration through Mr. Charles Whittaker, son of the Governor of the State, who kindly placed his time and conveyance at my disposal, and accompanied me to Fossil Lake, and the sandy region beyond. We returned via Silver Lake, and took the main road for the Dalles. This road runs north along the western edge of the sage- brush and the eastern border of the valley of the Des Chutes river. There is nothing to obstruct the view of the Cascade range from this road, and as the greatest elevation of the range is at its eastern border, the view of it from this road is the finest that can be ob- tained. At a point twenty to twenty-five miles south of Prineville, nearly half the length of the Oregonian portion of the range is included in the panorama, at a least distance of seventy-five miles. From the line of forest-covered mountains rise five magnificent snow-peaks to heights varying from 10,000 to nearly 15,000 feet above sea level. To the north is Hood; then succeeds Jefferson ; then Condon, Cope, and the Batchelor. As these mountains do not rise from a plateau as do those of Colorado, the effect they produce is more impressive than that of mountains of greater elevation in the latter region. The wedge of Hood and the cone of Jefferson only find their counterparts in the celebrated volcanoes of the Cor- dilleras, whose praises have been often celebrated ; but nowhere can five Cotopaxis be seen at one view, but in the Cascades of Oregon. They are ideal mountains, grandly simple, whose outlines, rising from base tosummit, are on ly interrupted by vast precipices. They pierce the blue sky with a vertical mile and more of purest white “as no fuller can white,” save where the crags are too steep for the snow to cling. When I first saw Mount Hood, nothing but its cone was visible, an island of light, floating in a sea of clouds. When I saw it last, clouds had again separated its summit from the earth, and the rays of the sun gave it an Alpengliihn which resembled the red glow of a furnace, rather than the cold sheen of the ice-peak. Mount Condon is a double mountain, consisting of two peaks with sharp Summits, connected by a high saddleback. Its outlines are as steep _as those of the others, and it presents an immense surface of snow. Mount Cope is twenty miles south. Its summit is an obtuse cone surrounded by impassible precipices. It is next to Mount 1002 Sketches of the Cascade Mountains of Oregon. Jefferson in elevation. These mountains are two of the four some- times called the “Three Sisters.” They were given distinct names by the late Dr. Hayden, director of the U. S. Geological Survey of the Territories, but his ill health and death prevented his issuing any publication on the subject. Mount Condon was dedi- cated to Professor Thomas Condon, of the University of Oregon, a distinguished teacher of geology, and the discoverer of the Miocene beds of the John Day river, of Oregon, which have produced so many remarkable vertebrate fossil remains. The Batchelor has an obtuse apex and resembles somewhat Mount Etna in its outline. A general view of these mountains is given in the accompanying sketches, which I took from two of our camps. One of the last views I gained of the snow-peaks was in the morning as the sun rose, The valley of the Des Chutes was, as before described, filled with white clouds, and these rose to such an elevation as to conceal all but the summits of the volcanic cones. As the sun’s rays rested on them they all glowed with such intensity that they could be well compared to masses of red-hot iron suspended in the heavens ; and by a stretch of imagination be conceived as once more in their hoary age, ablaze with their internal fires, attempting to revive the terrible glories of the past. Our road took us away from these sublime scenes of the upper world, to equally extraordinary, if not as gigantic exhibitions of the ancient activity of the volcanoes in the bowels of the earth. We descended into the canyon of the Des Chutes and followed its cvurse for many miles. The descent could not have been less than 2,000 feet, and was accomplished by zigzags and stages innumerable. Prof. Newberry has described this canyon in his report in the series of the U. S. Pacific R. R. Survey volumes. Its walls display & remarkable section of the materials which the eruptive forces cast far and wide, or forced to flow over this afflicted country. High upon the walls of the canyon isa horizontal layer of columnar basalt, the columns vertical. Below this, separated by many feet of a friable deposit, is a stratum of well defined, apparently sedimentary, rock. A deep bed of ash is followed below by another bed of columnar basalt, and this again after an intermediate soft stratum, by a third bed. In the two lower beds the columns are variously disposed, They are frequently curved, forming concentric arcs, Editors’ Table. 1003 disposed in various directions according to locality. Sometimes the columns are horizontal, resembling piled cord-wood, and all are generally regular and more or less artificial looking. From this extraordinary gorge we finally issued on a rolling country well covered with bunch-grass, which continued to our destination, the Dalles, on the Columbia river. ` EDITORY TABLE. EDITORS: E. D. COPE AND J. S. KINGSLEY. In the annual address of the President of the Biological Society of Washington, Mr. G. Brown Goode, Assistant Secretary of the Smithsonian Institution, uses the following language:! “I think the general tendency of a careful study of the distribution of scientific men and institutions, is to show that the people of the United States, except in so far as they sanction by their approval the work of scientific departments of the Government, and the institu- tions established by private munificence, have little reason to be proud of the national attitude towards science.” This indictment is brought after a careful survey of the ground bya naturalist of undoubted competency, and of exceptional opportunities for acquir- ing information. We are compelled to agree with Secretary Goode, and can, we think, point out some of the conditions of this state of affairs. Our complaint is that the average American citizen does not know what original scientific research is, and that if he acquires wealth, and wishes to do something for the benefit of his fellow- men, as he does more frequently than the citizen of any other country, he does not do anything for the production of knowledge. He devotes money to schools and to libraries, but towards the creation of the books to be used in them, and the truths to be taught in them, he does nothing. Forgetting the lessons of his business training, he apparently imagines that knowledge is derived from _ Some mysterious internal process of the mind, and that the producer 1 1887, pp. 92-3. 1004 Editors’ Table. needs neither material nor apparatus. He supposes that he can make money and scientific discoveries at the same time, and so does not need food, clothing, nor shelter. Or if these essentials be pro- vided, he exacts such an amount of teaching from the unfortunate recipient, that scientific production is suppressed at its fountain- head. Yet these good people like to talk about the scientific pro- gress of the age, and of the benefits that it confers on mankind, Of course most of this comes from an ignorance of what great fields of knowledge remain yet unexplored, and an incapacity to under- stand what a change will be wrought in our thoughts and acts by the acquisition of that knowledge. The solution of the great mystery of the relations of mind to matter has no interest for them; or, if it has, carries with it no impress of utility. Perhaps some people of little faith fear the results of such knowledge, not reflecting that it is better to traverse the paths of life and death with one’s eyes open, rather than with them shut. The actual state of original research in America justifies the lan- guage of Secretary Goode. The number of positions available for the original investigator in the country is small, and many of these are occupied by incompetent persons who add little or nothing to scien- tificknowledge. Our so-called “Academies of Science”! have become lyceums, where little beyond popular display and instruction is attempted. It is true that most of these societies publish “ Proceed- ings,” ete., but whence the material to fill these publications with worthy matter is to come, they do not concern themselves. The perversion of these societies from their true object is inevitable, so long as they are compelled to elect members for financial reasons. After Academies of Science come the Universities. Here the same spirit presents the same obstacles to research. But little time is granted the professors in most of them, and in one case the posi- tion has been distinctly announced, that original research does the University no good. The philistinism is here fairly expressed, and the issue is made. Continental Europe is, however, against this modern barbarism, and progress can still find congenial climes. Germany still turns out her volumes rich with observation and thought, on a financial basis so small as to furnish little more than buttons and kid gloves for a fashionable American family. 1 Except the U. S. National Academy. Recent Literature. 1005 But Americans are not Germans, replies a gentleman “of the old school”, If so, what is. the difference? We have the financial ability, and there is no deficiency of mind in certain classes in the United States. One answer is, that there is a dissociation of the mind and the money. Occasionally an attempt is made to effect a combination. Sometimes the method is grotesque; as when a wealthy merchant recently offered a University the sum of $200,000, to put his son through a four years’ course, and make him a professor afterwards, Sometimes the attempt is successful, as in the case of the Allis Laboratory of Milwaukee. We can only say may there be many Allises in the future of our history, and may they be as judicious in their selection of workmen. We suspect, however, that this state of affairs will not last. The Universities are doing their good work of educating the people, and from these will spring, from time to time, men who understand the growth of the human mind, and how to aid it.

WINCHELL’s GEOLOGICAL SruDIES.!—[In this work we have an aid to the study of Geology in its various departments, which will have a distinct influence in advancing the knowledge of the science. The student, whether in the school-room or in the field, will find its med undoubted, whether the clearness of the descriptions or the excellence of the illustrations be taken into account. The long experience of the distinguished author, both in original research, and in teaching, qualify him especially for the production of a work like the present. The departments of stratigraphic and dynamic geology may be specified as the best, as they are the most extended divisions of the book. We cannot speak as highly of the palæon- tological part. The list of the “ most important types of animals and plants,” beginning on page 305, is mostly constructed either after antiquated models, or else after false lights of modern character. The Vertebrata are especially bad, and the nomenclature adopted is mostly one which the student will have to forget, if he or she be so unfortunate as to have remembered it.

JORDAN’S MANUAL OF THE VERTEBRATES.'—In this, the latest ‘edition of this well-known work, Dr. Jordan has completely revised the text, turning it end for end, condensing and rewriting almost every page, as well as increasing its scope by admitting to its pages the littoral forms of the Atlantic Coast of the United States. The work is apparently fairly well done both by author and manu- facturer, though we might criticise the classification adopted in some cases, or pick out here and there errors of anatomical statement, for Dr. Jordan is confessedly no anatomist, but takes his structural knowledge at second hand. Books of this kind constitute the most popular and useful introductions to the sciences of which they treat, but it must be remembered that they constitute introductions only. e fault lies not in the keys but in the use to which they are put. They serve the poor teacher, and enable him to do the poor- est kind of work with the least possible expenditure of brain force. All he has to do is to give the student a bird or a fish and one of ` these manuals and the work is done. The poor student, imagining that he is deriving mental discipline by the operation, but not clearly realising where it comes in, struggles with the inoffensive fish or fowl down through pages of “keys,” until at last he cap- tures a Latin name which seems to fit it. As has been wittily said, “ it is like tracking a woodchuck to a hole, when you get there all you have isa hole.” ‘Yet this process is daily going on in hun- dreds of our high-schools and scores of our colleges to-day. In many an institution which rejoices under the name of University the biological „students never learn a single anatomical fact, never hear a single embryological statement; their whole knowledge o the varied forms of life around them consists in having learned the names of a few dozen vertebrates and flowering plants. While the botanical manuals of Wood and Gray are largely responsible for the wide taste for botany in the United States, they are too often regarded as the summum bonum of the science by the teacher. True zoologists must be on the alert or similar works upon the animal side will be used in the same superficial way. | -1 Jordan, David Starr.

GENERAL NOTES. GEOGRAPHY AND TRAVEL. GENERAL.—THE VOYAGES AND FATE or La PEROUSE.— Apropos of the centenary of the death of La Perouse, the Bulletin of the Geographical Society of France gives a summary of the voyages of that unfortunate navigator. The Boussole and the Astrolabe, under his command, left Brest August 1, 1785, doubled Cape Horn on February 8 of the next year, reached the Sandwich Islands in May, made the coast of America near Mount St. Elias on June 23, followed it to Monterey, and thence crossed the Pacific to Macao. On April 9, 1787, the expedition started again to reconnoitre the Japanese Isles and the coast of Tartary. The island of Dagelet was discovered May 27; the strait of La Perouse, between Sagha- lien and Jesso, soon after ; and on December 9 the vessels anchored at Mauna, one of the Navigator group. Here M. de Langle, the commander of the Boussole, together with the naturalist Lamanon and ten men, were surrounded by the natives and killed. The last letter that reached France from La Perouse was dated February 7, 1788. The story of the discovery of the remains of the expedition at Vanikoro, in the Fiji, is told by Vice Admiral Paris, the last survivor of the expedition sent out in 1826 under the orders of Dumont d’Urville. The Astrolabe, commanded by this captain, was only a small transport bearing the name of a corvette. At Vanikoro information was obtained that five bronze cannon and some skulls of Europeans were in possession of the natives, and also that a vessel had been wrecked there and its crew mas- sacred. The débris of the frigate Astrolabe was finally found opposite the village of Paiou. A monument to the memory ° La Perouse was raised upon the islet of Manevai. Asta.—Tuer ErunograpHy or Hrnpustay.—F. v Hellwald (Ausland, Nos. 31-35) has an article upon the ethnography of Hin- dustan. The 252,000,000 of inhabitants belong to four races, black, yellow, Turanian, and Aryan. The primitive popula consisted of two types, one Malay, still to be found in the south an on the Malabar coast; the other Semitic, still existing in the Nil- ghirries and in the north of India. This primitive population was driven back by Turanians descending the Brahmaputra valley A and these invasions precede the historical period. The mixture © these Turanians with the indigenes gave rise to the Protodravidas, 1 Edited by W. N. Lockington, Philadelphia, Pa. | Geography and Travel. 1009 and from the mingling of the latter with the Mongols arose the Dravidas or Tamals. The defiles of Afghanistan first let in the Turks, who spread over the Indus valleys, and afterwards the Aryans, who extended their rule to the Vindya Mountains, and further south became mingled with the older peoples, forming the Bheel, Dhang, and other tribes. In the eleventh century the various Mussulman peoples added to the ethnographical confusion. THE Amur VALLEY.—M. Venukoff contributes to the Sep- tember number of the Revue de Géographie an account of the region of the Amur, which he characterizes as fit for colonization. The vast country watered by the Amur and its affluents, the Zeya, Bureya, Tunguska, etc., flowing from the Stanovoy mountains, consists of fertile plains and rolling or rugged surfaces in about ual proportions. The fertile part comprises an area equal to a third of that of France. This plain country consists chiefly of five separate portions, two of which, that in the basin of Lake Evoron and that upon the lower Amur, have a fresh and humid climate, while the other three, higher up the Amur, and reaching to the base of the Touine, Wanda, and Little Khingan mountains, offer all that is necessary for the existence of European agriculturists. The population of these plains does not at present exceed 85,000 Russians, Chinese, Coreans, and Tungusians all told. Arrica.—Tur FRENCH IN SenEGAMBIA.—The progress of French rule in the Senegambian region since 1881 has been very considerable. At that date Colonel Borgnis Desbordes left St. Louis, imposed contributions on several rebellious chiefs and entered Kita early in 1882. Though he had only 220 fighting men and could expect no help from the timid indigenes, he entered into a campaign against Samory. The latter was defeated, and the town of Keniéra fell into the hands of the French. Those who doubt the propriety of European interference in Africa, would do well to read M. Pietri’s description of the sight which met the conquerors on entering the town. “In the plains around the village were corpses and their detached heads; a little farther rose heaps of cinders yet burning and mingled with the blackened bones of the prophet’s victims, and the wells of the village were also full of toe * * * * * * Our soldiers found some unfortunates still alive, suffering from ugly wounds, the executioners not having ad time to finish them. Even these horrors were less harrowing than the sight of the families of the victims, naked, fleshless, living statues of hunger who stretched out their arms to our soldiers praying for food.” In 1882 the same Colonel attacked and took Murgala and Daba, thus breaking the power of the Toucouleurs and also of the Bambaras, who bravely defended the latter town. Bamaku, on 1010 General Notes. the Niger, was reached early in 1883, but a league was formed against the French, and the Spahis, spite of their bravery and the great loss of the enemy, were compelled to retreat, only again to advance and gain victory after victory, thus assuring the domi- nation of the Upper Niger and the rule of a country equal toa third of France. The French in Senegambia soon encountered a new enemy in the person of Mahmadu Lamine, a Mussulman of Kayes, who resolved to found a new empire in the Sudan by playing the rôle of prophet. In 1886 the marabout had fifteen to twenty thousand men grouped around Kayes, yet by the end of the year his power was broken. A treaty was made with Samory in 1887. He accepted the Tankisso as the limits of his state and placed his country under French protection. ; M. Vigué (Rev. Sci., Oct. 27, 1888) contributes an interesting article on the tribes of Senegambia. Notwithstanding the chaos of tribes the author believes that all the indigenous peoples may be referred to two stocks ; one of them the Guinean proper, the other comprising the Mandingoes, Fulahs, and tribes formed by the intermingling of these two. 'The numerous foreign Sudanese, Walofs, Toucouleurs, etc., are not comprised in either of these categories. The peoples of the coast of Senegambia, all of them miserable fetichists, appear to be of the same stock with the more powerful tribes found farther south, such as the Ashantis and nations of the Lower Niger. These Guinean tribes have been pushed back by the invading Mandingos and Fulahs, until only a narrow strip on the coast was left to them, and would without doubt have disappeared altogether had it not been for the advent of Europeans. America.—M. THovar’s Conciusions.—The last expedition of M. Thouar in the region of the Chaco led him across a waterless desert and the sufferings of the party were very great. Seve men deserted, and out of twenty-one men only three returned alive. In his report presented to the Bolivian Government, M. thew came to the following conclusions: (1) That the northern aa the Chaco is entirely arid and waterless, (2) that the opening O p wagon road across this region is impracticable, (3) that a mune from Sucre to Pacheco would not pay, but (4) that the opening 0 the Pilcomayo needs only some simple works of canalization, Wer would be largely compensated by the profits drawn from the auriter- ous sands and fertile lands of its coast.

Stromé and Osteré, the two largest, have summits of 800 and 970 metres, and a mean altitude of 300 metres; they are cut up by deep valleys which are continuations of the fjords. All the islands are elevated and surrounded by cliffs. he group is composed of beds of basalt, mingled with carbonifer- ous strata. The volcanoes which produced the basalt must have n well to the west of the archipelago. The islands have a very humid climate; Torshavn receives two metres of rain annually, spread over 267 days of the year. The Faroé Islands were colonized in the ninth century. Chris- topher Columbus visited them in 1467. The inhabitants retain some traits of the old Vikings; they are tall and strong, with blonde hair and red beards. The women do not cover the head. he sheep is to the inhabitants of the Faroés what the reindeer is to the Laplanders, and its flesh, with the produce of the fisheries and the eggs of sea birds, constitute the main food of the islanders. Thorshavn is the political centre, but its harbor is obstructed by ice in the winter. Another important port is Kirdebée. THE OSCILLATIONS oF THE SWEDISH Coast.—M. L. Holm- strom (Revue Scientifique, Sep. 8) brings together the varied obser- vations of Celsius, Runeberg, Gissler, Nordenanckar, Hällström, Wikström, Lyell, Erdmann, Bruzelius, Forssman, Bortzell, ant others, relative to the changes of level in the coast of Sweden. ‘There is full proof of a lowering of thesea level on the western coast of Sweden during the last forty years. Marks cut in the rock show the level- Ings in 1847, 1867, and 1870, and the present level of the seaweed indicates an annual sinking of 0", 40. M. Holmstrom states that he knows no fact tending to show that the Norwegian coasts are now changing level, but those of Finland seem to vary in an analo- gous manner to those of Sweden. M. Holmstrom does not con- sider that the lowering of the sea level is by itself a proof of the Tising of the land, since it is now well known that the ocean service 1S not exactly spheroidal, but is elevated by the attraction of elevated continental masses. long as the relative masses of the continents remain the same no alteration can take place in the mean sea-level, but augmentation or diminution of the land masses cause a rising or falling of the -level, GEOGRAPHIC AL NEws.—EUuRoPE.— The mortality of Madrid during the last ten months has been forty-five per 1,000 and that of the last eight years has been 41.7. Epidemics of small-pox and diphtheria, caused by the defective sanitation of the city, largely account for this high mortality. 1012 General Notes. According to statistics brought together by M. Turquan, an average number of seventy-eight centenarians, twenty-seven men, and forty-six women, die annually in France. This average is based on 1,474 observations. The northern slope of the Pyrenees seems to be a favored region for longevity, since 38.8 per 100,000 in the Hautes Pyrénées and 38.4 in the Basses Pyrénées attain 190 years. The percentage diminishes northwards, but increases some- what in the basin of the Seine. The Bulletin of the Alpine Club states that immense caverns containing a subterranean lake and water-courses which seem to be connected with the river Yonte, have been discovered by M. Fabié in the Casse Mejean, an isolated mountain 900 to 1,300 metres In height. Asts.—Disguised as a Mussulman, Dr. Hurgronji, of Leyden, has resided six months at Mecca. The city has not sensibly changed since it was visited by Burkhardt, in the beginning of the century. This traveller denies that the black stone of the Kaaba is a meteorite, since a similar stone occurs in the sacred mountain of Abu Giibez. The old State of Harar, once governed by an independent emir, and afterwards annexed to Egypt, has, since March, 1887, been m the possession of Menelik, king of Shoa. het England took possession of the island of Socotra on Novem 30, 1886.

Geology and Paleontology. 1013 The atlas of Morocco, by M. de Foucauld, is a most valuable addition to the geography of the north of Africa. The lines of mountains and rivers shown on previous maps are here considerably modified. The Atlas range in Morocco is composed of three parallel chains instead of one, and the course of the Dra is found to be in its upper part half a degree to the west of its previously supposed position. Captain Pleigmeur, who was commissioned to study the levels across the French African territory, between the Atlantic Ocean and Stanley Pool, was drowned in the River Niari. The Northwestern African Trading Company, which succeeded to the rights of Mr. Mackenzie at Cape Juby, near the frontier of Morocco and opposite to the Canary Islands, imposes a duty o from ten to twenty per cent. upon merchandise going into Morocco. The factory of this company was recently attacked by the natives, and the director, M. Morris, was assassinated. In May, 1888, news was received from Cairo respecting Lupton, Slatin, and the other prisoners of the Mahdi. Their situation is the most miserable possible, they are condemned to the hardest and most humiliating tasks. To negotiate for their release wou trouble lost, to organize an expedition would be to hasten their death. None the less it is a shame to leave Europeans in this deplorable condition. GEOLOGY AND PALZONTOLOGY. DESCRIPTION or New Species oF FOSSILS FROM THE ROCK- FORD SHALES oF Iowa.—Professor Newberry, in speaking of the mingling of the Devonian fauna of Ohio, says: “ The mingling of the fauna of the Hamilton and Corniferous is apparently somewhat greater here than in New York, but this is readily explained by the fact that here, as in other portions of the Western States (Lowa included), there were no such striking alternations of conditions outs the successive deposition of strata as are indicated at the “An open sea prevailed throughout several successive periods at the west, and during these an unbroken series of limestone strata was formed, while at the east alternating shore and off-shore con- ditions interposed sheets of mechanical sediment, and gave more distinctness to the fauna of each formation.” 1 Geology of Ohio, Vol. I., p. 144. 1014 General Notes. Now, however applicable these statements may be to the Devon- ian rocks of other States, they certainly are not, to any such degree, applicable to the rocks of this age in Iowa. The Devonian rocks of this State, as observed by Dr. White,! are serially isolated. The occurrence of extensive beds of very coarse and fine-grained sandstone, varying from five feet to forty feet in thickness (some- times obliquely and discordently stratitied throughout), and blue and buff shales, some of which are extensively sun-cracked, and others containing abundant remains of land plants, as well as exten- sive beds of blue clay and hard, fine-grained and compact lime- stone, and the varying fauna of the several divisions, all attest that there were nearly equally as striking alternation of conditions during the successive deposition of strata in Iowa as are indicated “ at the east;” and that the alternating shore and off-shore conditions which interposed sheets of chemical and mechanical sediment, have, to a greater or less degree, given a distinctness to the fauna of the several divisions equal to that “ of the east.” ; An interestitfg and instructive feature of the exceedingly rich fauna of the Rockford Shales of Iowa is the extreme minuteness of a considerable number of its fossil species. Of these minutissi- mic, yet adult, forms, more than fifteen are Gastropoda, four Brachiopoda, three Crustaceans, four or five Foraminifers (suborder Perforata), and five or six small Bryozoan corals. These forms, which comprise slightly over one-seventh of all those known to occur in this formation, are usually well represented both as to genera, species and individuals. ‘ The organic life of the old Devonian sea in Iowa culminated in these shales; and at this time was ushered in a period when the conditions were much more favorable to the existence of life than at any other epoch of the Devonian age in this State. Immediately underlying the Rockford Shales is a stratum of dark blue be! from twenty. feet to twenty-five feet in thickness, and se 7 destitute of organic remains; this attesting conditions, when r material was laid down, extremely unfavorable to the existence 0 any form of life. Upon the ushering in of conditions under ego the material of the super-incumbent shales was deposited, t change from the pre-existing conditions was very abrupt.’ Although the change in the character of deposition here ie very sudden, yet the change as to congeniality to life seems no | ve been so rapid, as appears to be attested by the fact that near M all the depauperate forms above enumerated occur at the base these shales. 1 r ? 7 2 Sahel gies Bi beds or peated from the blue clay below to "a id and shales above, the change having been everywhere very rapid aD sharply defined.

As will be observed by the enumeration, Brachiopods form but an inconspicuous feature of the fauna at the base of the shales ; while the fauna of the higher horizons of this formation shows a preponderance, both as to numbers of species and individuals, of this class of organic remains. In general, the different classes of fossil remains, as Brachiopoda, Gastropoda, Crustaceans, etc., are restricted in their vertical range to certain definite horizons, and so do not occur in equal force throughout the entire formation.

The name _Saurodontide Cope should not be replaced by Saurocephalide of later origin, because Saurodontide Zittel, of later date than either, has been applied to another family, which should, if well defined, have another name. In the Batrachia, Professor Zittel divides the Stegocephali into three primary groups, the Lepospondyli, Temnospondyli, and Stereospondyli. In the first the vertebral centra consist of a simple sheath round the chorda dorsalis; in the second the centra are segmented ; and in the third they are amphiccelous and “ com- pletely ossified.” The author does not adopt the divisions Gano- cephala, Rhachitomi, and Embolomeri. There are serious objections to the system proposed by Prof. Zittel, which I will state. There does not seem to be any real difference between the Lepospondyli and the Stereospondyli, since a tubular vertebral centrum passes by the most insensible gradations into an amphiccelous one. The Temnospondyli cannot be regarded as homogeneous, or exactly defined. In fact, the vertebral centra of the Embolomera are not segmented, but are as entire as in the other two divisions of Zittel. € presence or absence of two occipital condyles is also a character not to be neglected in this connection. i The account of the Stegocephali (including Ganocephala, Rhachi- tomi, and Embolomeri) is the most complete ever placed in the hands of students ; in fact it is the only synopsis yet published. In the midst of this important monograph we are compelled to make two corrections. The lettering of the pelvis of Eryops (p. 364) is reversed in position. Secondly, the genus Stereorhachis Gaudry (P. 398) is not a Bratachian, but a reptile of the order Theromora, and probably of the family. Clepsydropidæ.—E. D. Cope. SCHLOSSER on CARNIVORA.!—The second part of Dr. Schlos- ser’s important memoir includes the lower Carnivora, or the Urside, Canide, and Mustelide. It includes much that is new on the subject, and by its thoroughness and critical character advances our knowledge of the European forms much,beyond any previous pub- lication. A number of new genera are added, as Pachycynodon in Canidæ; Pseudamphicyon in Ursidæ; and in Mustelidæ, Plesiocyon, Haplogale, Stenogale, and Pseudictis. He includes in the latter family Proælurus Filh. and denies that it is allied to the Nim- navide or Felidæ. He redefines the Urside (under the name Amphicyonide), so as to include besides Ursus and Hyznarctos,— ' Die i i n, Marsupialia, Creo- donten a Oaar, hippier, Inora : von Max Schlosser ; 4Tafeln ; 4to.

In the Canide, Dr. Schlosser appears to us to admit too many genera; at least we cannot clearly make out generic differences from his deseriptions. On the other hand the genera of Mustelide, though numerous, are sharply defined. We note a couple of errors in the matter of American species. Canis brachypus Cope is not an Eocene, but an upper Miocene species (Ticholeptus beds). Aelurodon ferox and Canis saevus cannot be well referred to different families, as they were established on the superior and inferior molars of the same species.

PETROGRAPHICAL News.—There have recently appeared two interesting papers upon the Cortlandt series of eruptive rocks, and the changes they produce in the surrounding mica-schists and lime- stones. The first paper is by Mr. J. EF. Kemp, who reports the results of his examinations of an extension of the series west 0 Stony Point, N. Y. He finds the eruptives to be of the same general character as those described by Dr. Williams,’ from near _ Peekskill. In one of these he notices the alteration of brown hornblende into green augite. He further finds that limestone upon the contact with these eruptives has undergone an alteration, during the course of which tremolite has been developed. Dr. Williams’s‘ paper deals with the contact phenomena observed in the rocks surrounding the eruptives in the Stony Point region. The unaltered mica-schists consist of quartz, biotite, muscovite, 4 little feldspar, tourmaline, and occasionally zircon. Upon approach- ing the eruptives they lose their foliati d havedeveloped in them: garnet, sillimanite, staurolite, scapolite, cyanite, margarite, ripidolite and corundum. The sillimanite is found in radiating bundles of fibres. The ripidolite (or clinoclor) js derived from the biotite of the schists. The margarite has the macroscopic appearance of muscovite. Tn the thin section, it is distinguished from this mineral by its high refractive index, its extinction of 6°-10°, its numerous twins par- allel to oP, and its large optical angle (114° in air). Its compo sition is: — ' Edited by Dr. W. S. Bayley, Colby University, Waterville, Me. 2 Amer. Jour. Sci., A , p. 247. ; Cf. Amer. Naturalist, 1886, p. 275 ; 1887, p. 569. Amer. Jour.

Most of these are holocrystalline. They contain plagio- clase, augite, magnetite, olivine and rounded quartzes. The quartz is usually surrounded by shells composed of little augite crystals, which extend out into the body of the rock, and are sometimes partly included within the feldspar. It has the characteristics of the porphyritic crystals of more acid volcanic rocks, and is regarded as original, The main portion of the paper is taken up with the discussion of the conditions under which the production of por- phyritic quartz crystals might take place in a rock as basic as basalt. fter a thorough examination into the effects which temperature, pressure, and the presence of water vapor exert upon the crystalli- zation of a molten magma, Mr. Iddings concludes that the quartzes owe their origin to certain physical conditions attending an early period of the magma’s existence ; and that of these the most impor- tant is the presence of water vapor under } ressure. In the same aper the writer describes two new occurrences of quartz basalt. he first is a red compact rock from the vicinity of Santa Maria Basin, in Arizona. The second is a dark-colored, fine-grained rock from the S. E. base of Anita Peak, Colorado.—Kroustchoff? has recently described an inclusion in the basalt from Wingendorf, in Silesia, which differs from most basalt inclusions in that it contains anorthite. This mineral and enstatite make up the larger part of the inclusion, which contains in addition to these, augite, diallage, ae and various spinels.

Hovey! reports the discovery of a cordierite gneiss at Guilford, sixteen miles east of New Haven, Conn. The cordierite has a deep blue color in the hand specimen, but under the microscope is colorless and very fresh. It contains as inclusions only sillimanite needles.—Lacroix and Baret? mention a pyroxenite om near Saint Nazaire, Loire-Inférieure, France, that is com- posed essentially of a granular mixture of augite, scapolite and sphene.—The microscopical examination and the determination of some of the physical constants of several sandstones, a marble and a tufa from California, have been made by Prof. A. W. Jackson, of the University of California. New Mrnerats— HouMANNITE AND AMARANTITE.—In a mass of copiapite from near Caracoles, in Chili, Frenzel* has dis- covered two new iron sulphates. One has been called hohmannite after its discoverer. This is an opaque chestnut-brown fibrous mineral, with a vitreous lustre. Its hardness is 3; specific gravity, 2.24, and its streak a yellow ochre color. Its composition may represented by Fe (FeO) (SO,), + 7H,O. It is insoluble in water, readily undergoes alteration, and loses 7.63 per cent. of water when placed in a dessicator over calcium chloride. The second mineral, amarantite, is probably identical with the first, although the author prefers to designate it by a separate name because of its different physical and chemical properties. Amarantite occurs in orange- colored microscopic crystals of the triclinic system.’ They have a citron-yellow streak, and a specific gravity of 2.11, and do not as readily undergo decomposition as does hohmannite.—Riebeckite. n a flesh-red granite from the Island of Socotro, in the Indian n, a hundred and fifty miles from Cape Gardafui, Sauer® has found a hornblende which corresponds exactly to aegerine among the augites.

It crystallizes in the orthorhombic system like brookite, but its axial ratio, as calculated by Des Cloizeaux, is 99275 : 1 : 92337. The color of the mineral is yellow or brown, art hardness about 6, specific gravity 4.285, and streak yellowish white. Rare Minerars.—Bertrandite. Heretofore this mineral has been found only in small crystals at various localities in Europe, and itserys- tallographic characteristics have not been thoroughly investigated. A new find at Mt. Antero, Colorado, affords Mr. Penfield‘ a crys- tal of sufficient size to admit of exact measurements of the crystal- lographic constants. According to Mr. Penfield, the mineral is orthorhombic with a: b : c = .5723: 1: .5953, and 2H = 101° 10’ for yellow light. The hemimorphic development of the basal plane cannot be explained. The crystals are attached to ques and are associated with phenacite, orthoclase, muscovite and fluorite. They have a hardness of 6-7, a specific gravity of 2.598, and consist of :— SiO, BeO CaO H:O 51.8 39.6 1.0 8.4 Piedmontite. The optical properties of the manganese epidote pied- montite have recently been very carefully studied by Dr. Kot6,’ of Japan, who finds it quite wide spread as a constituent of Japanese rocks, In a piedmontite-schist consisting of quartz, piedmontite, muscovite, garnet, rutile, feldspar, ete., the piedmontite is well crys- tallized with oP, œ Pj, 4 Pa, P, and Px predominating. The mineral has an extinction of 3°, and is pleochrois as follows: vr = deep reddish violet; t = brownish red; pi = light violet.

Near Brixlegg, in the Unterinne- thal, is a mineral, occurring in little spherical groups of crystals implanted on barite. Its analysis gave 86.89 per cent. of SrCO,, and 13.14 per cent. of CaCO,, thus agreeing very closely with Thomson’s emmonsite from Massachusetts. Cathrein has measured the crystals, and found them to consist of rhombic prisms with a : b : c = .6090: 1: .7236.—Diamonds and Sapphires. A new discovery of diamonds and sapphires is reported* from Australia. he location where they have been found is Invere, New South Wales. They are found in a sand made up of quartz and tourma- line, and pieces of a rock composed of the same minerals,—Leucite. Prof. Judd* announces the discovery of leucite by Mr. T. W. E. David in a leucite-basalt from Byrock, N. S. Wales, Australia, about 450 miles N. W. from Sydney. Leucite, which until a few years ago was not known outside of Europe, is now known to occur in each one of the continents with the exception of Africa.—Cryp- tolite, the rare cerium phosphate, according to Mallard,° is nothing but monazite with a habit differing slightly from that which this mineral usually affects.— Gadolinite has been found, by Lacroix,’ in a cavity in the granitite of the Mourne Mountains, Ireland, and allanite has been discovered, by Levy and Lacroix,’ in a granite from Pont Paul, Finistére.

France, xxxv.) the curious prop- erty of revivification possessed by Selaginella lepidophylla. When the root withers, each branch curls up, and the plant appears more or less in the form of a ball. In this state it is able to remain for a long time, and then when the water necessary for its growth is supplied, the branches unroll, the green color which had almost disappeared returns, and the branches and roots re-commence to grow. The structure of the plant is such that when dehydration occurs, the cells on one side of a branch are thicker than those on the other, thus they contract unequally and cause the branch to curl up.—Jour. Roy. Mic. Soc., Vug., 1888. PEDIASTRUM AND POLYEDRIUM.—Most botanists have had specimens of various species of both these genera under observa- tion, and probably few have suspected their real relationship. The flat discs of the former certainly bear little resemblance to the cal- trop-shaped groups of pointed cells of the latter. However, it appears that Askenasy has demonstrated that Polyedrium is but a stage of Pediastrum, or, to be more accurate, in statement, that Polyedrium polymorphum is a stage of Pediastrum boryanum.

A PROBABLE Case oF Instinct at FAULT IN Bees.—While staying for a day at a ranch in the valley of South Platte, in Colorado, a few years ago, I found some excellent honey served upon the ranchman’s table. He informed me that he had under- numbers, and while flowers were yet abundant his hives became well nigh depopulated, and few or no new swarms were ever pro- uced. Upon opening some of the forsaken hives he found them filled with comb, nearly or quite every cell of which was filled with honey. The hives seemed to be in excellent condition, and he found no trace of the presence of any enemy of the bees. : _ I examined one of the opened hives, which yet contained a por- tion of the honey in its comb, and so far as I could see, its condition entirely agreed with the ranchman’s statements. I also observed that his hives had been placed in the midst of many acres which were mostly covered with a natural and luxurious growth of the plant Clione integrifolia Torrey & Gray, from the flowers of which the bees had evidently obtained their honey. Suggestions as probably indicating the cause of the rapid extinction the bees could obtain the honey with remarkably little labor. Packard states that the life of working bees of the first brood of the season is about six weeks. Some apiarists think that durin the season of most active labor the life of those bees does not ex 1030 General Notes. amonth. May it not, therefore, have been the case that the workers to which fell the task of collecting honey brought it in such quantities and, so quickly, that all the comb-cells were filled before the queen had an opportunity to deposit her eggs? If this were the case the swarms necessarily became extinct by the natural limitation of the life of individual bees, because of the failure to keep up their numbers by breeding. In short is not this a case in which the instinctive struggle for existence defeated its object ? ave no intention of drawing a parallel between this case of disastrous results to bee-life under apparently normal and unusually favorable conditions, and a certain phase of human society, but if the foregoing suggestions are of little value for want of scientific verification they are believed to be deserving of consideration from other points of view.—C.

Garman describes (Bulletin Ill. State Lab. Nat. Hist.) a new earthworm from Champaign, Ill. This new genus belongs to the family Acanthodrilide of Claus, but it differs from the other members of the family in several important characters. Its nearest relation is Acanthodrilus of Africa and the Orient. Among - most noticeable features are the absence of a sub-neural vesset, the existence of a double dorsal vessel, the two halves being yo rated throughout their length, except where they pass through = dissipiments between the somites. Although not mentioned by Mr. Garman, this character of the central circulatory organ pos- Zoology. 1031 sesses considerable morphological interest when taken in connection with the method of formation of the “ heart ” in many Arthropods, e.g., Branchipus (Claus) and Oecanthus (Ayers). The paper con- cludes with a valuable catalogue of the known American species of earthworms, which we summarize here: amily Lumpricip#.—Genus Tetragonurus Eisen, T. pupa Eisen. Genus Allolobophora Eisen, A. beckii Eisen, A. riparia Hoffmann, A. fetida Savigny, A. subrubicunda Eisen, A. mucosa Eisen, A. turgida Eisen, A. tenuis Eisen, A. tumida Eisen, A. parva Eisen, A. nordenskioldii Eisen.

Family ACANTHODRILIDZ.—Genus Diplocardia Garman, D. communis Garman. b Family PLUTELLIDÆ.—Genus Plutellus Perrier, O. heteroporus errier, Family PERICHÆTIDÆ.—Genus Pericheta. Mr. Garman states that an undetermined species of this oriental genus has been accli- matized in the green houses at Champaign, Ill. on either side of the “stomach,” which resembled the “shell-gland” of the Entomostraca. The opening of the gland occurred at the of the second maxilla, and its lumen contained concretions of urates (so shown by Murexide test) ; points which demonstrated its homology with the shell-gland of the Entomostraca. This is its rst recognition in the Malacostraca, though the author found it later in Porcellio, Idotea, Nesæa, Cymothoa, and Jeera. E Larva or Prorevs.—Dr. Ernst Zeller has been so fortunate as to have a Proteus anguineus lay seventy-six eggs in captivity, from which in ninety days two larvee hatched. Accord- tng to his description in the Zoologischer Anzeiger (Bd. XI., p. 570, 1888), the larvæ when hatched were more developed than is the case in Amblystoma and the “ Axolotl,” and measured 22 mm. in length, of which five belonged to the tail. The general appear- ance was much like that of the adult. The pale red gills are shorter and less developed than in the adult; the anterior limbs are well developed and three-toed, but the hinder pair are still stump-like. The development of the small black eyes is notice- able, as is also the development of pigment in various regions © the A few points are mentioned concerning the embryonic 1032 General Notes. development, and of the larv for two weeks after development, when they possessed two toes to the hind feet. or arny to make two journeys of over twenty-six hundred miles each. At the time of my first visit, the first week in April, all eggs had been laid, and the ovaries of adult female alligators were full of eggs of all sizes up to 26 mm. in diameter. I returned to Florida June 4th, and found that I was still somewhat early, as the nests were then being built. With the aid of five experienced hunters I at last succeeded in finding, on the 9th of J une, a nest, evidently just completed, in which there were twenty-nine eggs. The next day, at a point forty miles further north, a second nest was found with thirty-one eggs. There were many nests found, old and new, but only these two contained eggs. : The nests vary much in size, the largest being about 24 metres 1n diameter at the base, and 80 cm. high in the central part, the whole having the shape of a rounded cone. They are located generally on a slightly elevated place, which is higher by a metre, or slightly more than the surrounding level, and covered with a thick growth of palmettos, mangroves, magnolias, etc. These are celled “ hum- mocks” by the natives. On one side of the hummock at least, ın some cases on all sides, is a pond from one to two metres in depth, and in the bank, under water, the female alligator digs a cave, which in some cases extends three metres under the hummock, an which is always close to her nest. The nest is made by paige? together a great pile of dead leaves and twigs and humus whic forms the surface of the ground, and which is arranged with some care. The inside is made of the more finely divided—almost Pole. dery—material of the deeper layers of the top soil, while the outside, even to the top, is covered with twigs and leaves which are whole or but little broken, and with many of the long, unbroken arat or needles of the southern pine. ` The eggs are deposited gr 20 cm. from the top, and in the nests were found lying on top Jl one another, making rows or layers, with the fine humus filling & the interstices. The top of the nest is always exposed to the sun. Dr. Clarke describes the eggs as very difficult to manipulate, aS- Entomology. 1033 the shell membrane is tough, and the white very sticky. Before studying his eggs he took them to Williamstown, Mass., but before arriving there they had undergone a part of their develop- ment, and the neural folds had nearly completed their coalescence. ANATOMY oF Brrps.—Mr. F. E. Beddard (P. Z. 8S., London, 1888) gives an account of the alimentary tract and syrinx of Balæniceps rex, from which, and from the previously known osteological peculiarities, he regards this bird, “in fact, as a rather aberrant heron, having no near affinities with the storks, nor to Scopus.” In the same volume he has some notes on the visceral anatomy of the penguins and puffns, dealing especially with the oblique septum of these birds, and the morphological and taxonomic conclusions to be drawn therefrom. He is inclined to homologize it in details with a fibrous and even muscular stracture found in the crocodile. Dr. R. W. Schufeldt (Jour. Comp. Anat. and Sur- gery, October, 1888) gives a much needed account of the osteology of the Jungle-fowl, Gallus bankiva. He also treats of several other important structures in the same bird, which is of especial interest as being the ancestor of all of our domestic fowl. Some thirty process figures illustrate the chief points in the article. ENTOMOLOGY." CoLOR-RELATIONS BETWEEN PUPÆ AND THEIR SURROUND- INGS.—Students of Lepidoptera often observe variations in the color of different pups of the same species, that have apparently been caused by the color of the object to which the pupa is attached. Striking instances of these variations came under the observation of the writer during the past summer, when breeding Papilio asterias. Pupz attached to green leaves were bright green in color, while others attached to the sides of a breeding-cage closely resembled in color the wood upon which they were. This class of phenomena has been made the subject of careful study by several English entomologists. The more important ot the papers published are two in number. The first, by Mr. E. B. Poulton,? was read before the Royal Society of London last year. Since that time Mr. George C. Griffiths has carried the matter farther, and the results of his experiments have just been published by Mr. William White.’ * This Department is edited by Prof. J. H. Comstock, Cornell Uni- versity, Ithaca, N. Y., to whom communications, books for notice, ete., should be sent. * Philosophical Transactions, Vol. clxxviii., B., 1887, pp. 311-441. * Trans. Entomol. Sce., London, 1888, pp. 247-267. 1034 General Notes. Previous to these writings, observers had freely stated that it was the habit of chrysalides to assume the precise coloration of the sur- face to which they were attached, and the untested facts of the case had been considerably exaggerated. In explanation of the phe- nomena in question, the earlier writers held that these correspond- ences of color were analogous to those of the Chameleon, or that they were photographic. Attention was called to the transparent surface of the freshly formed pupa, which might be sensitive to ight. Professor Meldola, however, had modified such statements by declaring! that “the action of light upon the sensitive skin of a pupa had no analogy with its action on any known photographic chemieal. No known substance retained permanently the color reflected on it by adjacent objects.” 4 This represents the state of our knowledge at the time of the publi- cation of Mr. Poulton’s memoir. In this paper the results of many experiments are tabulated, Some of them are very striking. Thus, in the case of pupæ of Vanessa, exposed to gilded surroundings, many of them appeared as if they had been covered with gol . This memoir isa difficult one to abstract, owing to the great amount of details. The following appear to be the more important conclu- sions :— 1. There is a great difference with regards to the sensitiveness of different species. Thus he proves that the pups of the following named butterflies possess an adjustable color-relation to their sur- roundings: Vanessa io, V. urtice, V. atalanta, Pieris brassice, and P. rape, while, on the other hand, dimorphic pupe, which are closely allied to the sensitive forms, may be uninfluenced by r rounding colors, e.g.: Papilio machaon and P. polydamus. +8 the genus Ephyra (Heterocera) the dimorphic pupæ are quite pe f influenced by their surroundings, the pupal colors corresponding to those of the dimorphic larvæ. : 2. The previously accepted theory, which explained the pune! color-relation as following from the action of light upon the mols skin of the freshly-formed pupa, is entirely disproved, and "A shown that the influence works upon the Jarva during the peri which intervenes between the cessation of feeding and pupation. _ This intervening period was carefully investigated in V. rag and it was found that, after ceasing to feed, the larve wander a variable time, then rest for about fifteen hours upon the su cP selected for pupation, and finally hang suspended, head PEE for about eighteen hours, after which time pupation takes pice By transferring the larve from one color to another, in that the color influence works for about twenty hours pr g the last twelve hours of the whole period. | Proc. Entom. Soc., London, 1874, p. XXIV. Entomology. 1035 3. Blinding proved that the eyes do not form the organs which are influenced, and it was also shown that the complex ‘briatles do not contain a terminal organ with this function. Experiments with conflicting colors appear to prove that surrounding colors affect the whole surface of the larval skin, although parti-colored upæ were not obtained. (There is, however, some evidence of such a result in Papilio nireus.) 4. In all cases there are certain colors which produce no effects. In Vanessa the brilliant metallic tints of the pupe can be greatly influenced by the presence of gilded surfaces in the environment of the larva before pupation. This fact appears to prove that the metallic tints are essentially protective, and probably subserve con- cealment by their resemblance to glittering minerals, such as mica. his theory is confirmed by observations upon the habits of certain species with gilded pups. At the same time the gilded appearance as acquired another and opposite significance im other species, being of use in rendering the pupæ conspicuous, and thus acting as a signal of an unpleasant taste or smell. _ 5. The amount of pigment in the superficial layer of the cuticle in the pupæ of Pieris brassice and P. rape appears to be influen by the spectroscopic composition of the light incident upon the larvae before pupation. : e experiments of Mr. Griffiths, as summarised 7 Mr. White, confirms Mr. Poulton’s observations in the following pupæ produced by black, and of green pupæ produced by yellow. (4) The special effects of yellow surroundings in arresting the formation of dark superficial pigment, and in tending towards the production of green pups, were very striking, and confirm Poulton’s suggestion that rays from this part of the spectrum, Serious INJURY TO APPLES BY THE PLUM CurcuLio.— ng the latter part of the past summer my attention was 1036 General Notes. attracted to a serious injury done to the fruit in an apple-orchard through which I passed daily. A large proportion of the apples in one corner of the orchard had been eaten into by something which made small pits from one-eighth to one-fourth inch in diameter, and of about the same depth. On one tree nearly every apple had been attacked, and in many cases there were ten or twelve holes in a single apple. The injury was so serious as to render the fruit in this part of the orchard unmarketable. The holes in the apples were first observed during the latter part of August. At that time many of them were partially grown over, while others were fresh, indicating that the pest had been at work for a considerable time, and was still active. As the injury to the apples resemble somewhat that caused by a climbing cut-worm, that sometimes infests apples in western New York, I at first searched for caterpillars, and gave little thought to the plum curculios that I frequently found hiding in the pits in theapples. But, after finding a considerable number of these insects in these pits, it occurred to me that they might the cause of the mischief, Several perfect apples were then selected and placed in breeding-cages, in each of which were con- ned several curculios. The question was soon settled. Within twenty-four hours the beetles had begun to eat into the apples. They made small holes at first, but these were soon enlarged so as to form pits of the size indicated above. : The results of this experiment are of special interest at this time as confirming the observations referred to in the next note.— J. H. Comstock POISONING THE PLUM CURCULIO.— In referring to some expert ments made by me to prevent curculio injuries, in the August NATURALIST, the question is raised as to how spraying with poison may have a preventive effect on this insect. I believe that 4 satisfactory explanation may now be given. Early last June I confined an adult curculio in a jar with a large green plum, an was surprised at the avidity with which the fruit was eaten. ie large portion of the surface was gnawed out for food, and not ‘sult purposes of oviposition, and the feasibility of p the a beetles by coating the fruit with poison is clearly shown. 45 But even more satisfactory breeding-cage experiments were ma ee in Illinois, by Professor Forbes, who informs me that he has ei that, besides gnawing out the fruit, the adult curculio eats vane of the substances of the leaves. He adds that the curculios sak certainly very freely exposed to destruction by poison, ve v” reference to the habits of oviposition or the first food of the larvæ; and that he has “also learned experimentally that spray ng. ” leaves with Paris green would poison the beetles completely: Embryology. 1037 Professor Forbes discussed at some length the details of his experi- ments, which confirm the conclusions reached in my experiments, in an address delivered at a meeting of the Central Illinois Horti- cultural Society during last August.

SMITR’S MONOGRAPH OF THE SPHINGIDE OF TEMPERATE NORTH America.—Parts II. and III. of the current volume of the Transactions of the American Entomological Society are devoted to a “ Monograph of the Sphingide of Temperate North America,” by Mr. John B. Smith. This paper makes a volume of nearly 200 pages. It appears to be very complete, and very carefully written. The synonymy of each species is given ; the adult is fully described, and descriptions of the early stages are also given whenever they are known. The work abounds in valuable critical notes. Analytical keys for the separation of genera and of species are furnished. The paper concludes with a synonymical list. Eighty species are enumerated in this list. This work should be in the hands of every student of American Lepidoptera. EMBRYOLOGY. DEVELOPMENT OF MELOE.—Josef Nusbaum describes briefly (Biol. Centraiblat., VIIL., p. 449-452) the development of the oil tle, Meloe. This form is very convenient for embryological studies as it breeds well in confinement and lays little piles of eggs, all the eggs in a single pile developing synchronously. The Segmentation nucleus is central and the cells resulting from the entation migrate slowly to the surface, the protoplasm forming a reticulum in the meshes of which the yolk is embraced. Some of these cells reach the surface to form the blastoderm while others remain behind to form “ yolk cells.” On the third day the ventral Plate and the rudiments of the amnion appear very early the ventral plate becomes segmented, and paired appendages appear on every Segment of the body. The primitive groove appears at the same time as the amnion and develops from behind forward. It soon closes and forms a tube with a very narrow lumen behind, in front a solid cellular in-pushing. This is regarded as gastrulation, and the portion thus invaginated as ento-mesoderm or primary entoderm, ‘ Edited by Prof, John A. Ryder, Univ. of Penna., Philadelphia. 1038 General Notes. from the hinder portion of this cells, are cut off, which wander in and join the “ yolk cells.” but have nothing to do with the forma- tion of the mesenteron. The remainder of the primary entoderm differentiates into two large lateral and a middle solid longitudinal and, and in the former there appears in each segment a cavity. The outer wall of this cavity forms the somatopleure, the inner the splanchnopleure and epithelium of the digestive tract. This inner wall soon separates completely from the outer in the middle line, and there becomes two-layered, thus developing both entoderm and splanchnopleure. These lateral bands of entoderm now unite with the middle one and soon enclose the whole yolk and the “ yolk cells” which latter later degenerate and are absorbed.—J.S. K. MICROSCOPY." VITAL INFUSION or Nerves WITH METRYL-BLUE.—Prof. Ehrlich’s? experiments in staining nerves with methyl-blue, mark the second great advance in staining living tissues. The discovery ot a veritable nerve-stain, that acts intra vitam, has already led to the settlement of many disputed points, and promises to furnish a means for deciding the problem of nerve-endings. The well-known color-reaction induced in newly formed bone-substance as the result of madder-feeding, is outshone by this wonderful reaction between methyl-blue and the axis-cylinder. l According to Ehrlich two conditions are necessary in order to e the methyl-blue reaction : These are (1) saturation with oxygen an (2) alkaline reaction. The first condition can be secured only be free exposure of the object to the air. If a cover-slip is used, the air is thus excluded, and the stain rapidly disappears. As to the second condition, it is known that nerves at rest have an alkaline reaction. It is necessary, therefore, to experiment re resting nerves. The state of rest may be forced by severing ‘ nerves before infusion with methyl-blue, or by poisoning the animals © with curare. The nerve-endings of the retina may be studied me animals that have been kept some time in the dark before infusio ; The number of nerve terminations that stain under ordinary ae ditions is, however, so great, that a wide field for histological aie tigation is open to us without having recourse to the expedients J mentioned, se 1 Edited by C.

Wochenschr., 1886, No. 4. ~ Microscopy. 1039 The evanescence of the color-reaction is a serious drawback, but this difficulty has been met with some success by the use of iodine and picro-carmine as “ fixing ” reagents. The method of procedure, according to Prof. ©. Arnstein, '! and his pupils, Dogiel and Smirnon, is as follows :— nject the vena cutanea magna of a frog with 1 ce. of a satu- rated solution of methyl-blue. The tongue and palate are at once colored, but the coloring substance is confined to the blood-vessels, and does not at first affect the nerves. After an hour or two the nerves supplying the taste papille appear blue, and at the same time the nerve-meshes of the palate are also stained. The motor nerve- ends show the stain a little later. The color-reaction only lasts a short time, often not more than five to ten minutes. It should be fixed at the moment of its greatest intensity. If iodine is used for this purpose, proceed as follows: — : lace the frog in a 1 per cent. aqueous solution of potassic lodide, in which metallic iodine has been dissolved to saturation, and inject the blood-vessels with the same solution, thus freeing them from the blood as far as possible. Next cut out the parts needed and leave them in the iodine solution from six to twelve hours. Transfer to water and leave until most of the iodine has been withdrawn. As the result of this treatment, the nerves will have a dark brown or grey color, and the surrounding tissue will nearly colorless, 5. Mount in acidified glycerine. Picro-carmine as a “ fixing ” agent, is said to give more dura- na preparations than iodine, Bat the latter gives the more intense color i Mammals and birds die soon after injection of methyl-blue, so that a true intra vitam reaction can not be easily obtained. How- ever, a very satisfactory reaction may be obtained, with these animals, after death from chloroform. The injection may be made from the eart or from any blood-vessel. The appearance of i color in the nerves can be followed under the microscope, and when its maximum has been reached, the fixing reagent applied. r Finally, with a dilute solution of methyl-blue, preparations can be stained directly on the slide. The retina of fishes, birds, an mammals, can be more successfully stained this way than by Injection, Dr. Max J oseph? has tested Ehrlich’s method on Heteropods and found that the clear intra vitam stain could not be satisfactorily fixed. He remarks that the commercial methyl-blue is unfit for use, , Anat. Anz. ii., 1887, No. 5, p. 125, and No. 17, p. 551. Anat.

Biedermann’ has employed nearly the same method for Crustacea and insects. CENTRAL TERMINATION OF THE OPTIC NERVE IN VERTE- BRATES.’—For tracing the course of nerve-fibres, the following method has been employed with great success by Prof. Bellonci. — 1. The brain, or a part of it containing the nervus opticus, is placed in osmic acid (4 to 1 per cent.) for fourteen to twenty ours, 2. Sections are then made with free hand in aleohol of 70 per cent. ; the sections are washed in distilled water a few minutes, and then placed in 80 per cent. alcohol three or four hours. 3. The sections are again placed in distilled water, and then transferred to the object-slide, and covered with a cover-slip. 4, A few drops of ammonia are then allowed to mix with the water under the cover-slip. This reagent makes the brain trans- parent as glass, with exception of the nerve-fibres, which remain black, and which are brought out with such distinctness that their course is easily followed. : The sections are of course thick, but this is an advantage in tracing the winding course of the fibres. ‘ Sections cut in celloidin with the microtome can be treated in same manner, but the action of the ammonia is much slower, requiring several days. DoUBLE-STAINING OF THE CENTRAL Nervous SysTEM.’— . Of the various fluids used for hardening, a 3 to 4 per a solution of bichromate of potassium gives the best results. P object must be in a fresh condition when placed in the fluid, an the fluid must be changed often during the process of hanes: 2. The sections are best when made, without imbedding in cet- loidin, from pieces fastened to cork with gum and then placed in alcohol long enough to harden the gum.‘ 1 Sitzb. d. Kaiz. Akad. d.

The color differentiation at once appears: The white matter becomes blue or violet, and the gray matter red. Bundles of fibres in longitudinal section appear to be made up partly of blue and partly of red fibres. Cross-sections show that the difference in color among the fibres is due to the presence in varying amount of two unlike substances in the medullary sheaths. These substances may be distinguished as erythrophilous (red) and cyanophilous (blue). The axis-cylinder is uniformly red, while the medullary sheaths are variegated. In some fibres the whole sheath is made up of cyanophilous matter, in others of erythrophilous matter. In the majority of the fibres, the sheath is composed of concentric layers, blue alternating with red. In the gray matter of the spinal chord may be seen Gerlach’s net-work of fine fibrils. Close examination shows that the fibril is differentiated into red axis-cylinder and blue medullary sheath. Preparations after the above method are not permanent, but they sometimes keep for a year or more. Such preparations show that the medullary sheath is a structure of more importance than has generally been supposed by physiolo- gists and pathologists. The hist brought out by this process of double-staining appear to indicate a difference in function among the nerve-fibres. The division into motor and sensory fibres, as Sahli suggests, may not go to the root of the matter. The central hervous system may be built up on a much more complicated principle of division.

THE WEsTERN Society or Naturauists held its first annual meeting October 24th and 25th, 1888, in the Physical Lecture- room of the Illinois State University, Champaign, Ill. Twenty- six members, representing six States, were in attendance. The meeting was called to order by the President, Dr. S. A. Forbes, and welcomed to the State and to Champaign by Prof. T. J. Burrill, Vice-President of the University. The first paper, on the“ Teach- ing of Botany,” was by Dr. D. H. Campbell, of Indiana University. He advocated the logical method of beginning with the simple and leading up to the complex, even with pupils as young as those in the high-schools, and the constant use of the compound micro- scope. The discussion which followed showed considerable diver- sity of opinion as to method, but all were agreed in relegating the analysis of flowers to the background. The other paper of the afternoon was by Prof. W. J. Beal, of the Michigan Agricultural College, who gave an account of a museum of plant products. In the evening, Dr. S. A.

Chamberlain, of the Wisconsin State University, detailed the methods of investigation in quaternary geology. 2 ; hursday morning the following papers were read: “ Collegiate Instruction in Physiology,” by Prof. O. P. Jenkins, of DePauw University ; “Collegiate Instruction in Geology,” by Prof. Samuel Calvin, of Iowa University ; and “ Biology in the High School,” by Prof. W. H. Hatch, of Rock Island. Prof. J. T. Burrill exhibited a convenient and compact apparatus for taking photo- graphs of microscopic objects, and explained its use. Prof. O. P. Jenkins exhibited a simple microtome invented by Prof. J . P. Naylor, which would cut ribbons of sections, the thinness of which is only limited by the pitch of the screw and the edge of the razor, while the instrument could be manufactured at a profit for ten or fifteen dollars. The following officers were elected for the ensuing year: President, Dr. T. C. Chamberlain, of Madison, Wis.; Vice- Presidents, Prof. J. T. Burrill, of Champaign, Ill., Pres. D.

It was 1044 General Notes. voted to hold the next annual meeting in Madison, Wis., in Octo- ber, 1889, the exact date to be set by the Executive Committee. Friday afternoon, after the transaction of some business, Dr. S. A. Forbes and Prof. H. Garman presented an account of the methods of investigating the contagious diseases of insects. Dr. C. O. Whitman, after giving several hints in matters of micro- scopical and embryological technique, outlined his plans for an inland biological laboratory, for which he asked the co-operation and active support of the colleges and universities of the North- west. Prof. W. A. Locy, of Lake Forest University, read a paper on the “Teaching of Zoology in Colleges.” Prof. Josua Lindahl exhibited a simple instrument he had devised for obtaining the contours and outline sections of skulls and other objects. After passing the usual resolutions and also one expressing their interest and intention to aid in the establishment of the laboratory advo- cated by Dr. Whitman, the Society adjourned. AMERICAN ASSOCIATION FOR THE ADVANCEMENT OF SCIENCE. — Report of the committee to secure from Congress the abolition of the duties on scientific books and apparatus imported into this country. —The committee made the following report :— Shortly after its appointment Dr. J. S. Billings resigned, sug- ting that a member from the West be selected to fill his place. rof. Langley, president of the Association, therefore appointed Prof. A. H. Worthen, of Springfield, Ill., to the vacancy. Upon the death of Prof. Worthen, which followed not long after, Prof. S. A. Forbes of Champaign, Ill., was selected by Prof. Langley to fill his place. The eastern members of the committee, Paof. J. R. Eastman and Prof. E. D. Cope, chairman, have held several meetings with the following results. The following resolution was adopted and signed by all the members :— lish-speaking country. ee ey Also all apparatus, instruments and material to be used in scientific ex- periment or original research ; decision as to the intention of the importer to rest with a committee of the U. S. National Academy of Sciences. This resolution was placed in the hands of the Committee of Ways and Means of the House of Representatives of which the Hon. R. Q. Mills is chairman, through Hon. W. C. P. Breckinridge of Kentucky, one of its members. The resolutions were received with consideration and had the attention of the committee while engaged in framing what is known as the Mills Tariff Bill. The Proceedings of Scientific Societies. 1045 recommendations contained in the resolutions were partially in- corporated into the bill in the following language (H. R. 9051, p. 1 and 7). Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, that on and after the first day of July, 1888, the following articles mentioned in this section, when im- ported, shall be exempt from duty: : ‘‘ Bibles, books and pamphlets printed in other languages than English, and books and pamphlets and all publications of Foreign Governments, and publications of Foreign Societies, historical or scientific, printed for gratuitous distribution.” This provision, although not covering the case of scientific pub- lications produced in England, is a great advance over previous legislation on the subject. As it is probable that the Mills bill in its present shape will not pass the Senate, and as the Senate is preparing a tariff bill as a sub- stitute for it, the resolutions of your committee have been sub- mitted to the committee of the Senate engaged in preparing this bill, of which Senator W. B. Allison is chairman. There is every reason to believe that the suggestions therein contained will re- ceive the respectful consideration of that committee. It has been hoped that some relief from the tax on knowledge at present imposed by the government of the United States might _ ‘| Whereas, the cause of education in science is retarded by the restric- tions placed by Congress on the importa on of scientific books and ap- gators, and are but rarely duplicated in this country : whereas the value of scientific apparatus is in nearly all cases dep t ofthe maker : and whereas colleg di i permitted to import apparatus duty free, while private investigators, usu- ally less able to yh ed : f “ Be it resolved, That ———— hereby requests the Representatives o thestate of —— in the Congress of the United States to use all pos- 1046 General Notes. sible efforts to have placed on the free list, books pertaining to the physi- cal, natural and medical sciences, and apparatus intended for purposes of scientific research or of education : and further be it “ Resolved, That a copy of these preambles and resolutions be forwarded to each member of Congress.” These resolutions were sent, by resolution of the same society, to the faculties of the universities and colleges throughout the United States for their approval and signature. Replies express- ing this approval and signed by the faculties, or their accredited officers, were received from the following institutions :— The American Philosophical Society, Philadel hia; The Franklin Institute, Philadelphia ; the Academy of Natura Sciences, Philadel- . . ne City ; Union College, New York ; Kenyon College, Ohio; N orthwestern iversi Colles. Ohio ; University of Vir- ginia, Na ne d e Va. ; Cornell University, Ithaca, N.

Our efforts have been mainly directed to the removal of the duty on books, under the belief that success in this direction will pre- > the way for further advance. We have not, however, neg- ected this important subject. The Mills tariff bill thus refers to it (pp. 27 and 32): (p. 82.) “And on and after October first, 1888, in lieu of the duties heretofore imposed on the articles hereinafter mentioned in this section, there shall be levied, collected and paid the following rates of duty on Philosophical apparatus and instruments, twenty-five per centum ad valorem. Your committee hope to be able to secure the total abolition of the duties on foreign books of science, and the great reduction, if not abolition, of those on apparatus. We base this hope on the activity in the direction of change in the existing laws on this sub- ject, at present existing in Congress, and the evident desire of the representatives of both the great political parties of the country to legislate for the best interests of their constituents, as they under z stand them. At the moment of preparing this report it is not Scientifie News. 1047 possible to announce any final result of the action of your com- mittee, but it is quite possible that improved legislation may be attained by the time of the meeting of the Association to which this report is made. In conclusion we find that what is needed to effect the result desired, is a continuation of the effort, already commenced, o vigorous protest against the laws on the subject as at present ex- isting ; laws which obstruct knowledge at its fountain-head ; which impose onerous burdens on a class which works gratuitously for the public good, and which place our country in a false position among the enlightened nations of the earth.

HE sedimentary rocks of Burlington have afforded such unri- valed facilities for the study of an extensive piscine and crin- oidal fauna that attention has been almost totally diverted not only from other well represented faunal groups, but also the equally interesting stratigraphical and cenological features of that vicinity. While the palzontological researches were being so assiduously car- ried on, regional stratigraphy necessarily received, at divers times, more or less consideration, and is comparatively well understood. Recently a detailed investigation of the superficial deposits of the region was instituted, and a preliminary notice of the observations over a limited area is herewith presented. The general geographical features of the annexed map have been compiled from Powers’ map of the city of Burlington and a por= tion of the map of Des Moines county, as given in Andreas’ His- torical Atlas of Iowa. In a few minor particulars, observation has necessitated some corrections and additions. The hypsometrical features are approximately accurate—the contours (twenty feet apart) _ having been, for the most part, constructed from measured street and railway elevations, and, especially in the northern third of the area represented, from measurements personally made with level and rod. Over certain areas of limited extent estimates from points of prominence were also made. Along the eastern margins of North and Prospect hills the contours should in reality form a single line, — but it has been deemed more advisable, for reasons hereafter stated, 1050 Surface Geology of Burlington. to deviate slightly from actuality, and project the individual con- tours distinctly. The drift over the region cartographically represented in Plate XXIII, exhibits only the “ Lower Till”—the southern boundary of the “ Upper Till,” or the till of the second glacial epoch, being con- siderably to the northwestward. Over this portion of the state the drift is usually more or less modified superficially, The boulders contained are for the most part comparatively few and of small size; they are seldom more than five or six feet in diameter, though a few miles from Burlington one is to be seen, the diametric measure- ment of which is more than fifteen feet. The preglacial surface expression of the region under consideration has manifestly not been completely obliterated by glaciation and the concomitant depositions, and the present topographic features are consequently in greater or less degree dependent upon the subjacent stratigraphic rocks which make up the greater portion of the altitude of the bluffs on either side of the Mississippi river at this point. The extreme attenuation of the till over the more elevated areas, and the deep accumulations of drift materials over the less elevated places, is evidenced by numerous exposures. In the valleys of Flint, Hawkeye and other smaller creeks, the depositions of the till attain a maximum thick- ness in some places of seventy or eighty feet. The city of Burlington is built upon four “hills,” all of which _ rise to a height of nearly two hundred feet above low water ' in the - Mississippi river at that place. Perhaps five-sixths of the altitude _ is formed of Burlington limestone and Kinderhook shales, which along the Mississippi river at Prospect and North hills, and also some parts bordering Flint creek, rise from the water’s edge in high mural escarpments. North of Hawkeye creek is a nearly insulated plateau, all sides of which are scalloped by steep-sided ravines, very deep toward the lower extremities, but interiorly becoming quickly lessened in depth, "1 This is the basis of all elevations given in the accompanying Map, and is assumed to be 510.77 feet above the sea-level. It was determined from a line of precise levels recently run by the Mississippi River Com- mission up the Mississippi river from the Gulf of Mexico, which gives the elevation of the U. S. P. B.

To the northeastward is a small subsidiary plain of subdued undulatory topography, evi- dently in no way dependent upon the underlying stratigraphic rocks. It rises thirty or more feet above the broad alluvial flood plain of the Mississippi river, and is divided by the Flint creek. Southwestward it passes rather abruptly into the comparatively gentle slopes of the general plateau. It manifestly occupies the preglacially corroded valley of Flint creek, and laterally rests upon the irregularly eroded slopes of the ancient water course. A section of this limited auxilliary plain exhibits the following structure: the €xposure is continuous for nearly half a mile on Flint creek, and is practically similar throughout. SECTION I.' 1.

It is over- laid by six to eight feet of typical loess, containing numerous small leesskindchen. The deposits here presented have an exposed thickness of sixty feet, and are seen to lean against the steep sides, the rather narrow gorge preglacially eroded by the waters of Flint creek to a depth of more than one hundred and thirty feet. North of Flint creek, and beyond the area represented in the annexed map, the topography in its general aspect is similar to that of the insulated plateau south.

Upon removal of the drift materials glacial scorings and strie on the subjacent paleozoic stratum have been disclosed in various laces, South of the Hawkeye creek rises a broad elevated plain so level in many places as to be almost devoid of natural drainage. North- eastward it is scalloped by short, deep ravines, but eastward it abruptly terminates with a perpendicular declivity, washed at its base by the Mississippi river, which has evidently separated the plateau from the highland of Henderson county, Illinois. To the southward and westward this level elevated plain gradually becomes gently undulatory and finally more broken by the small tributaries of Be ie creek. Northwestward it merges into the general elevated PLATE XXIII. Sr Surface Geology of Burlington. 1053 _ plain occupying the greater portion of the county.

The quaternary bedi of the two places are manifestly continuous, but the elevation of the latter section is somewhat less than the former, and the deposits are all intensified; No. 1 of section III. having a thickness of six feet, No. 2 of 13 feet, and Nos. 3 and 4 together, of 6 feet.

Summarizing the observations herein briefly recorded, it is to be noted: (1) That the loess at Burlington, as in other portions of Towa, occurs only over the elevated areas, and the fossils contai | are all depauperate, evidencing, as pointed out by McGee and Call,' a much lower temperature of the air than at the present time, for it : is also urged by those writers that the deposits of loess took place in ice-bound basins ; (2) that the loess over the region under con- sideration has been hp atmospheric agencies more or less modified superficially, often to a depth of five or six feet—the upper portion losing ‘entirely its original character, but downward passing by insensible gradations into typical loess.

ON THE INFLUENCE OF CIRCUMSTANCES ON THE ACTIONS AND HABITS OF ANIMALS, AND THAT OF THE ACTIONS AND HABITS OF LIVING BODIES, AS CAUSES © WHICH MODIFY THEIR ORGANIZATION. BY J. B, P. A. LAMARCK.? (Continued from page 972.) Ngee which proves it, is that this is not true of the organ of hearing, which is always found in animals where the nature of their organization requires it. This is the reason. The material of sound, that which is moved by the shock or ' vibrations of bodies, transmits to the organ of hearing impression which it has received from them, and penetrates every- where, traversing all media, and even the masses of the most solid 1 U. S. Geol. Sur., Sixth Ann. Rep. * Translated by Dr. E. E. Galt, from the edition of 1809. Influence of circumstances on the Actions of Animals, 1055 bodies; any animal which possesses a plan of organization in which hearing is essential, has always occasion to exercise this organ in whatever place it inhabits. Therefore, among vertebrate animals, one sees none which are deprived of the organ of hearing; but below them, when the same organ is wanting, we do not find this sense in any of the animals of succeeding classes. It is not thus with the organ of sight, for one sees that organ disappear, reappear, and disappear again, by reason of the possibility or the impossibility of the animals exercising it. In the Mollusques acephales, the great development of the mantle has rendered their eyes and their head altogether useless, These organs, although taking part in a wider plan of organization which comprehends them, have neces- sarily disappeared and become obliterated by constant disuse. Finally it enters into the plan of organization of reptiles, as of other vertebrate animals, that they should have four feet belonging to their skeletons. Serpents should have, consequently, also four feet, the more so as they do not constitute the last order of reptiles, and since they are less related to fishes than are batrachians (frogs, sala- manders, etc.) Now, snakes having adopted the habit of crawling on the ground, and of hiding themselves under bushes, their bodies, in consequence of long-repeated efforts to elongate themselves, in order to pass into narrow places, have acquired a considerable length, and in no wise proportionate to their thickness. Now, feet would have been very useless to these animals, and without employ- ment. Long feet would have been a hindrance to creeping, and very short feet, even to the number of four, would have been inca- pable of moving their bodies. Thus, the disuse of these parts having become constant in the races of these animals, has caused these same parts to disappear entirely, although they were really in the plan of organization of animals of their class. Many insects, Which from the natural character of their order, and also of their genus, should have wings, lack them more or less completely, from disuse. Numbers of Coleoptera, Orthoptera, Hymenoptera, and Hemiptera, etc., present examples, their habits never permitting them to make use of their wings. But it is not enough to give the explanation of the cause which has brought about the condition of organs of different animals, conditions which one sees always the — Same in those of like species. It is necessary besides to show these 1056 Influence of circumstances on the Actions of Animals. changes of conditions acting in the organs of some one individual during its life as the sole result of a great change in the habits peculiar to the individuals of its species. The following remark- able fact fully proves the influence of habits on the condition of organs, and how continued changes in the habits of an individual bring changes in the state of the organs which enter into action during the exercise of these habits. M. Tenon, member of the Institute, has communicated to the Classe des Sciences, that having examined the intestinal canal of many men who haye been ardent drinkers during a great part of their life, has constantly found it shortened to an extraordinary degree compared with the same organ of all those who had not a like habit. It isknown that great drinkers or those who are given to drunkenness, take very little solid food; that they eat almost nothing, and that the drink which they take in abundance and frequently, suffices for their nourishment. Since fluid aliment, and, above all, spiritous drinks, do not remain long either in the stomach or in the intestines, the stomach and the rest of the intestinal canal loses in drunkards the habit of distention. So also in persons of sedentary habits, and constantly applied to mental work, who habituate themselves to take very little nourish- ment. Gradually, in time, their stomachs contract, and their intes- tines become shortened. It is not a question here of shrinking and shortening produced by a contraction of parts which would permit of ordinary extension, if in place of a maintained vacancy _ these viscera should become filled ; but it is a question of real shrinks ing and considerable shortening, so that these organs would rather burst than yield suddenly to the causes which would produce ordinary distension. Circumstances of age being entirely equal, _ compare a man who habitually devotes himself to studies and mental _ work, who has rendered. his digestion sluggish, has contracted _ the habit of eating very little, with another who habitually and often takes much exercise and eats well; the stomach of the first would have reduced functions, and a very small quantity of aliment would fill it, whilst that of the second would be preser x and even increased. See then an organ greatly modified in 1ts dimensions and functions by the one cause of a change in its habits during the life of the individual. The frequent employment of an organ in becoming adapted to its habits, augments the function ‘umoJ ‘NOISuTang ye SUOLI "§ “OI ee gale tie "g DIA ‘org SAISY GLVId Influence of circumstances on the Actions of Animals. 1057 of that organ, develops it, and makes it acquire dimensions and force of action which it has not in animals which exercise it less, One comes to see that the disuse of an organ which has existed, modifies, impoverishes, and finally obliterates it. I will now demonstrate that the continual employment of an organ, with the efforts made in keeping its place in the circumstances under which it exists, strengthens, extends, and increases that organ, or creates new ones which are able to exercise the functions which have become necessary. The bird that hunger (necessity) attracts to water to find there the prey on which it lives, separates its toes and its feet when it strikes the water, and moves on its surface. The skin which unites these toes at their base, acquire the habit of extending themselves by these perpetual spreadings; thus, after a time, the large membranes are formed which we see uniting the toes of ducks, geese, ete. The same efforts made to swim, that is to say, to push the water in order to advance and move in that liquid, have developed the same mem- brane which is between the toes of frogs, sea-turtles, the otter, the beaver, ete. On the contrary, the bird that its manner of life habituates to roost in trees, and who proceeds from individuals who have all contracted that habit, has necessarily the toes more elon- gated and shaped otherwise than those of aquatic animals which I have cited. Their nails, after a time, become long, sharp, and curved in a hook by holding so often the limbs on which the animal rests. So it is known of river birds who do not swim, and who only desire to approach the borders of the water to find their prey, are continually exposed to being forced into the mud. Now this bird, wishing to act so that its body may not be wet, makes great efforts to extend and elongate its feet. It follows from the continued habits which this bird, and all those of its race have contracted in continually extending and elongating its legs, that the individ- uals of this race are found elevated on stilts, and have also gradu- ally obtained long boots. That is to say, they are denuded of eathers as far as the thighs and often beyond (Systeme des Animaus sans Vertebres, p. 14). It is known also that the same bird, wishing to pick without wetting its body, is obliged to make continuous efforts to elongate its neck, Now, to the continuance of these habitual efforts in this individual, and those of its race, they owe that, after 1058 Influence of circumstances on the Actions of Animals. a time, they acquire the singular elongation of the neck, as is seen in river birds. If some swimming birds, as the swan and the goose, and of which the feet are short, have, nevertheless, a very long neck, it is because in walking in the water they have the habit of plunging their heads below as deeply as they are able, to take the aquatic larve and different animalcules which nourish them, and that they have no reason for stretching their feet. If an animal, for the satisfaction of its wants, should make repeated efforts to elongate its tongue, it would acquire considerable length (e.g., the ant-eater, the “pic-verd”). If it wants to seize something with the same member, then its tongue will divide and become forked. That of humming-birds, who seize with-their tongue, and of lizards and snakes, who use theirs to feel and investigate bodies which are before them, are the proofs of that which I advance. Wants, always occasioned by circumstances, and followed by continued efforts to satisfy them, are not limited in their results to modify, that is to say, to augument or diminish, the extent or the functions of these organs, but they succeed in displacing these same organs — where certain of these wants make it a necessity. Fishes which swim habitually in large bodies of water, having occasion to see laterally, have their eyes placed on the sides of the head. Their body, more or less flattened according to the species, has its edges perpendicular to the plane of the water, and their eyes are placed in such a manner that they have an eye on each flattened side. But those fishes whose habits involve the necessity of con- stantly approaching rivers, particularly rivers little inclined or with gentle descent, have been forced to swim with one side downwards in order to be able to approach near the edges of the water In this situation, receiving more light from above than below, and having particular reason for always being attentive to that which they find above the water, this want has forced one of their eyes to undergo a kind of displacement, and to take the very singular situa- tion which is known in soles, turbots, “ limandes,” ete. (the Pleuro- nectes and the “Achires”), The situation of these eyes is not symmetrical, because there has resulted an incomplete mutation’ _ Now this mutation is entirely finished in the rays, where the trans- _ verse flattening of the body is altogether horizontal; so with the Influence of circumstances on the Actions of Animals, 1059 head. Thus the eyes of rays, both placed on the superior face, are rendered symmetrical, Snakes which crawl on the surface of the earth, having reason principally to see elevated objects, or those which are above them, this necessity has influence on the situation of the organ of sight in these animals, and, in fact, it has placed the eyes in the lateral and superior part of the head, in position to perceive easily that which is above them or at their sides, but they cannot see that which is above them or but little distance in front. Now, forced to make up for the lack of sight in recognizing objects which are before them, and which might hurt them in advancing, they have been able to feel these objects only by aid of their tongue, : which has obliged them to stretch it out with all their might. This habit has not only contributed to render this tongue thin, very long, and very contractile, but further, has forced it to divide itself, in a great number of species, to feel several objects at a time ; it has formed an opening at the extremity of their muzzle, to pass without being obliged to open the jaws. Nothing is more remarkable than the production of habits in herbivorous mammals. The quadrupeds to which circumstances and the wants which they have brought about, have given the habit of browsing on herbs, walk only on the earth, and find themselves obliged to rest on their four feet the great part of their life, execu- ting generally few of the ordinary movements of other Mammalia. The considerable time which this kind of animal is forced to employ every day, to replenish itself with the only kind of food which it uses, requires that it make little movement, that it employ only its eet to sustain itself on the ground, to walk or run, and that it never exerts itself to hang to or to grasp the trees. From this habit of consuming all day, great quantities of alimentative mate- rials which distend the organs which receive it, and of makiug only ordinary movements, it has resulted that the bodies of these animals are considerably thickened, become heavy and massive, and have acquired a very great volume, as one sees in the elephant, rhinoce- ros, cattle, buffalo, deer, ete. e, T A E d +L The habit of resting upright on thei g the greater part of the day to browse, has caused a thick hoof to grow, which envelope their toes ; and as these toes are resting without exercising any move- 1060 Influence of circumstances on the Actions of Animals. ment, and are serving no other purpose than to sustain them as well as the rest of the foot, the greater part of them are shortened, are obliterated, and so finally disappear. Thus, in the pachyderms; some have five toes on the feet enveloped in horn, and in conse- quence their hoof is divided into five parts; others have only four, and others still only three. But in the ruminants, the most ancient of mammals, which are confined to sustaining themselves on the ground, there are only two toes to the feet. It is also found that there is but one toe in solipedes (the horse, the ass). Now, among these herbivorous animals, and particularly amoug the ruminants, it is found that, from the circumstances of the wild country which they inhabit, they are constantly exposed to become the prey of carnivorous animals, and to be able to find safety only in precipitate flight. Necessity has then forced them to exercise themselves in rapid running; and from the habit which they have acquired, their bodies have become more slight, and their limbs slenderer : one sees examples in the antelope, gazelles, etc. The deer, roe-buck; fallow-deer, etc., are exposed to perish by the chase, or pursuit by man. This risk has reduced them to the same necessity, has constrained them to the same habits, and has produced the same results in them. The ruminant animals, being able to use their feet only to sustain themselves, and having little strength in their jaws, which are used only in cropping and browsing the herbs, they are able to strike blows only with the head, directing one against the other with the top of that region. In their fits of rage, which are frequent, especially among the males, their “ senti- ment interieur,” by these efforts directs more strongly the fluids toward that part of the head, and causes there a secretion of horny material in some, and of both osseous and horny material w others, which gives to them solid protuberances. This is the origin of horns and bosses, with which the greater number of these ani- mals have the head armed. It is curious to observe the product of the habits in the peculiar form and the height of the giraffe (Camelo- pardalis). It is known that this animal, the tallest of mammals, inhabits the interior of Africa, and that it lives in places where the earth is almost always arid and without herbage, so that it is obliged _ to browse the leaves of the trees, and to force itself continually to reach them. It results from this long-continued habit, in all indi- Influence of circumstances on the Actions of Animals. 1061 viduals of its race, that the front limbs have become longer than the hind ones, and that its neck is much elongated; that the giraffe, without rising on its hind feet, elevates its head and attains to six metres in height (nearly twenty feet). Among birds, the ostriches, deprived of the faculty of flight, and elevated on very high limbs, truly owe their singular conformation to analogous circumstances. The result of habits is also as remark- able in carnivorous mammals as it is in the herbivorous, but it shows its effects in another way. In fact, those mammals who are habituated, as well as their race, to climb, to scratch, in order to excavate the earth ; to rend, to attack; to put to death other ani- mals which may be their prey, have had occasion to use their toes. Now, this habit has favored the separation of their toes, and on them has formed the claws with which we see them armed. Among the carnivores it is found that they are obliged to employ the chase to take their prey. Now, those of these ani- mals who want, and consequently have the habit of rending with the claws, are compelled to force them deeply into the body of the other animal in order to hold it, and afterwards the effort made to tear the seized part has, by these repeated efforts, procured for those nails a size and a curve which would then have impeded them much in walking or running on stony ground. It results in this case that the animal has been obliged to make efforts to draw back these too projecting and crooked claws, and it results in, little by ~ little, the formation of these peculiar grooves into which cats tigers, lions, etc., retract their claws when not in use. ‘Thus, efforts in. some directions, long-continued or habitually made by certain parts of a living body to satisfy wants caused by nature or by circumstances, increase these parts, and they acquire dimensions and a form which they would never have attained if these efforts had not become the habitual action of the animals which employ them. Observations made on all known animals would everywhere furnish examples of it. What is more striking than what the kangaroo offers us? This animal, which carries its little ones in the pouch which it has under its abdomen, has acquired the habit of holding itself upright, poised only on its hind feet and on its tail, and of moving only by the aid of a series of leaps, in which it preserves its upright attitude so as not to hurt its little ones, 1062 Influence of circumstances on the Actions of Animals. Behold, then, what is the result? First.—Its front legs, of which it makes very little use, and upon which it supports itself only an instant when it leaves its upright attitude, have never acquired a development proportional to those of other parts, and have remained slender, very small, and almost without strength. Second.—The hind limbs, almost continually in action to sustain all the body, when leap- ing, have, on the contrary, attained a considerable development, and have become large and strong. Third.—Finally, the tail, which we'see greatly employed in sustaining the animal, and in executing its principal movements, has acquired at its base a breadth and a force extremely remarkable. These well-known facts are assuredly well calculated to prove that which results from the habitual use by animals of an organ or of some part. If, when we observe in an animal an organ particularly developed, and strong and powerful, — it is claimed that its habitual exercise has done nothing to produce that result ; that its continued.disuse makes it lose nothing, and that, finally, this organ has always been such as we find it since the creation of the species to which this animal belongs, I demand why our domestic ducks are not able to fly as the wild ducks; in a word, I will bring a multitude of examples to our notice, which will attest the differences resulting to us from the exercise or the lack of exer- cise of some of our organs, although these differences be not maim- tained in successive generations. In that case their results might be still more considerable. I observe, in the second place, that when the will determines an animal to some action, the organs which should execute this action are immediately excited by the influence of subtle fiuids (of the nervous fluid), which becomes the determining cause of the movements which cause the action m question. A multitude of observations prove this fact. It results that the multiplied repetitions of these acts of organiza- tion strengthen, expand, develop, and also create the organs which are necessary. It is necessary only to observe attentively that which happens everywhere in this respect, to be convinced of the basis of _ this cause of the development of organic changes. A Now, all changes acquired in an organ in consequence of a habit employed sufficiently to have an effect, is preserved afterward by ~ generation, if it is common to the individuals who in fecundation _ unite for the reproduction of their species. Finally this change 15 - Influence of circumstances on the Actions of Animals. 1063 propagated and passes thus into all the individuals which follow, and who are placed in the same circumstances, without which they would be obliged to acquire it in the same manner in which it has already been created. Moreover, in these reproductive unions, the mix- ture between individuals which have different qualities and forms, necessarily opposes the constant propagation of these qualities an forms. ' I.—It is this which prevents in man, accidental qualities or defects due to circumstances to which he is exposed from preserving and propagating themselves by generation. II.—If two individuals who have acquired peculiarities of form or defects be united, in this case they will reproduce the same peculiarities in successive generations. And if they restrict themselves to like unions, a particular and distinct race will then be formed. But the perpetual mixture between individuals which have not the same peculiarities of forms will destroy all the pecu- liarities acquired by particular circumstances. From this one can be assured that if distances of habitation had not separated men, the crossing, by generation, would have destroyed the general characters which distinguish different nations. If I should pass in review all the classes, all the orders, all the genera, and all the species of animals which exist, I would be able to show that the conformation of individuals and of their parts, that their organs, their functions, ete., ete., are everywhere only the result of circumstances in which every species finds itself surrounded by nature, and of the habits which the individuals which compose it have been obliged to adopt, and that they are not the result of an existing primitive form which has forced these animals to adopt their habits. It is known that the animal which is called the Ai, or the sloth, (Bradypus tridactylus), is constantly in a state of so great feebleness that it executes very slow and limited movements, and that it walks with great difficulty on the ground. Its movements are so slow that it is claimed that it is able to take only fifty steps in a day. It is known also that the organization of this animal is in all respects harmonious with its condition of feebleness or its inability to walk, and that if it wished to make other movements than those Which it is known to execute, it would not be able. If we sup- _ 1064 Influence of circumstances on the Actions of Animals. pose that this animal has received from nature the organization which it possesses, we must believe that this organization has forced it to adopt the habits and miserable state in which it is found. I hesitate to believe thus, for I am convinced that the habits which the individuals of the race of the Ai have been forced to contract originally, have necessarily brought their organization to its present state. That since continual danger has formerly made the individuals of this species take refuge in trees, to live there habitually, and to sustain themselves there on their leaves, it is evident that they must be deprived of a multitude of movements which animals who live on the ground are in the habit of making. All the wants of the Ai have been then reduced to the hanging on the branches, to creeping, or to crawling to get the leaves, and after- wards to resting on the tree in a state of inactivity, and always to avoid falling to the earth. Besides, this kind of inactivity would be constantly encouraged by the heat of the climate; for, with ani- mals of warm blood, heat predisposes them more to rest than to movement. Now, the individuals of the race of the Ai having for a long time preserved the habit of resting on trees, and of making only slow and little varied movements which suffice for their wants, their organization, little by little, would be brought into harmony with their new habits, and this would be the result: 1st.—That the arms of these animals making continual efforts to embrace easily the branches of the trees, will have lengthened ; 2d.—That the nails of their toes will have acquired much length and a curved form by sustained efforts to cling; 3d.—That their toes, having only exercise in particular movements, will have lost all mobility, will have re- united, and will have preserved only the ability of bending or of traightening themselves altogether ; 4th. —That their thighs, embra- cing continually the trunk and the great branches of the trees, will have contracted an habitual bowing, which will have helped to enlarge the pelvis, and to direct the cotyloid cavities backward 4 5th.—Finally, that a great number of their bones will have conso dated, and that thus many parts of their skeleton will have acquired a tendency and a form appropriate to their habits, and contrary sh those which they would have had under other habits. = No one is able to contest this,since nature, ina thousand other : ways, constantly shows us analogous examples of the power of cir- Influence of circumstances on the Actions of Animals. 1065 cumstances on the habits, and in that of habits on the forms, the dis- position,and the proportion of the parts of animals. A great numder of citations being unnecessary, the point of discussion reduces itself to this. The fact is, that diverse animals have each, according to their genus and their species, particular habits, and always an organiza- tion which is perfectly in harmony with those habits. From the consideration of this fact it seems*that one is at liberty to admit one or the other of the two following hypotheses, neither of which can be proved. Conclusions admitted at this time: (1) Nature (or its Author, in creating animals has foreseen all possible kinds of circumstances in which they may have to live, and has given to each species a permanent organization, as well as a pre-determined form invari- able in its parts; that it forces each species to live in the places and the climates where one finds them, and to preserve there the habits which it has. 2. My own conclusion: Nature in producing successively all species of animals, and commencing by the most imperfect or simple, to terminate its work by the most perfect, has gradually complicated their organization, and these animals, spread- ing themselves gradually into all habitable regions of the globe- each species has been subjected to the influence of the circumstances in which it is; and these have produced the habits which we observe and the modifications of its parts. The first of these two conclusions is that which has been held to the present time, that is to say, it supposes in each animal a per- manent organization and parts which have never varied and which will never vary; it supposes still thatthe circumstances of the places Which each species of animal inhabits never vary in these places) for if they should vary, the same animals would not be able to live there, and the possibility of recognizing such elsewhere, and of going or transporting themselves there, would be denied them. The second conclusion is mine. It supposes that, by the influence of circumstances on the habits and that which follows these habits on the organization, that each animal would receive in its parts and organization, modifications susceptible of becoming very consider able, and thus to have given origin to the state in which we find all animals, To prove that this second conclusion is without founda- Hon, it is necessary to first prove that no point of the surface of the A 1066 Influence of circumstances on the Actions of Animals. surface of the globe has ever varied its nature, its exposure, its elevation, its climate, etc., etc.; and to prove farther that no part of an animal undergoes, after a length of time, any modifications due to change of circumstances and from the necessity which constrains them to a kind of life and of action different from that which has been habitual with them. Now, if only one fact proves that an animal, after a long time of domestication, differs from the wild species from which it came, and if among the domesticated species there is found a great difference of conformation among individuals who have been subjected to a given habit, and those who have been constrained to adopt a differ- ent habit, then it will be certain that the first conclusion does not conform to the laws of nature and that, on the contrary, the second is perfectly in accord with them. All agree then to prove my as- sertion: that it is neither the form of the body nor of its parts which gives origin to the habits and the manner of life of the ani- mals; but it is, on the contrary, the habits, the manner of life and all the other influential circumstances, which have, with time, con- structed the form of the body and of the parts of the animals. With “new forms new faculties have been acquired, and little by little ‘Nature has come to form animals, such as we actually see them. Can there be in Natural history a more important consideration and to which one should give more attention than that which I ex- pound? i Evolution of Mammalian Molars. 1067 THE EVOLUTION OF MAMMALIAN MOLARS TO AND FROM THE TRITUBERCULAR TYPE. BY HENRY FAIRFIELD OSBORN. HE dentition in the recent Mammalia is so diverse that the most sanguine evolutionist of fifteen years ago could not have anti- cipated the discovery of a common type of molar, in both jaws, as universal among the Mmamalia of an early period as the penta- dactyle foot, and as central in its capacity for development into the widely specialized recent types. The tritubercular molar, discovered by Professor Cope in the Puerco, is exactly such a type, and may be considered with the pentadactyle foot as playing a somewhat analogous rôle in mamma- lian history, with this important difference—the unmodified penta- dactyle foot was probably inherited direct from the reptiles, and its subsequent evolution, with a few exceptions, has been in the direc- tion of the greater or less reduction of primitive elements towards special adaptation, as, to borrow an extreme illustration, in the transition from Phenacodus with 26 elements in the manus to Equus with only 12 such elements. On the other hand, the tritu- bercular tooth was not inherited, but in all probability developed within the mammalian stock, from a hypothetical form with almost, - If not quite simple conical molars, implanted by single fangs, in a ` nearly homodont series.? No such primitive type of mammalian dentition is actually known, although Dromotherium approximates it; but the apparent reversion to this type among the Cetacea, and apparent retention of it in the Edentata,’ support all the independent evidence upon this point derived from the Mesozoic The principle of growth was the regular addition of new parts to the simple cone, not at random, but according to a certain definite ' Read in the geological section of the British Association at Bath, September, 1888, Read in abstract by Prof. Cope, National Academy is Sciences, at New Haven, Nov., 1888. * See Author “ Structure and Classification of the Mesozoic Mamma- lia.” Jour.

Trans., 1887, p. 458. 1068 Evolution of Mammalian Molars. order which apparently progressed independently in different phyla, through a series of sub-tritubercular stages until trituberculy ' was attained. The tritubercular molar consists essentially of three cusps, form- ing what may be called the primitive triangles, so disposed that the upper and lower molars alternate. This, when attained, formed a central stage from which the great majority of recent molar types have diverged by the addition, modification and reduction of cusps; we must except the Monotremes, the Edentates, and possibly the Cetaceans, although there is considerable evidence that the cetacean molars were once of the triconodont type.? Among extinct orders, the Multituberculata (Plagiaulax, Tritylodon, etc.) must also be excepted from this series and discussion. The almost universal predominance of trituberculy in the early geological periods, is very significant of the uniformity of molar origin. Of twenty known Mesozoic genera,’ all except three * show trituberculy in some of its stages. As to the Lower Eocene, eighty- two Puerco species, representing twenty-six genera and five orders (Creodonta, Tillodontia, Lemuroidea, Condylarthra, Amblypoda), only four species have quadritubercular teeth, all the remainder are tritubercular.’ Prof. Riitimeyer has recently pointed out the pre- dominance of this type in the nearly parallel Egerkingen beds The contemporary Cernaysien fauna in the collection of Dr. Le- moine at Rheims, recently examined by the writer, shows exclu- sively tritubercular molars or their derivatives. By the Middle Eocene the lines of divergence towards the existing types of molars were well advanced, but trituberculy persisted in the dentition of several orders, in which it is found to-day (Lemuroidea, Insectivora, Carnivora, and many Marsupialia). | 1 First employed by Riitimeyer, “Ueber Einige Bezi ehungen zwischen den Säugethierstämmen Alter und Neuer Welt.” Abh. d. schweiz. pal. gesellsch., Vol. XV., 1888,"p. 54. 2 See Brandt, “Die Fossilen u.

Evolution of Mammalian Molars. 1069 It follows that it is quite as essential for the comparative anato- mist to thoroughly grasp the meaning and history of each of the component cusps of the tritubercular molar and of their derivatives, as it is to perfectly understand the elements of the manus and pes. For, the homologies of the cusps can now be determined almost as certainly as those of the digits. Take a human molar, for example, every component tubercle has its pedigree, and it can be demon- strated, almost beyond a doubt, which of these tubercles is homolo- - gous with the single reptilian cone. The writer recently (op. cit., p. 242) proposed the adoption of a distinct nomenclature for the different cusps of the tritubercular molar, and offered a series of terms for the primary cusps based as far as possible upon the prim- itive position and order of development, and in most instances in accord with their secondary position. This nomenclature can be extended to the secondary cusps in the sextubercular superior, and quinquetubercular inferior molars. The terms now in general use are based, for the most part, upon the secondary or acquired posi- tion, and in no instance upon the homologies of the cusps in the upper and lower molars, or even in corresponding molars of differ- ent genera, thus involving much confusion. For example, the Antero-internal cusp of the lower molar of Mioclenus is not homol- ogous with the antero-internal cusp of Hyopsodus, nor with the antero-internal cusps of the upper molar of either genus. The present contribution is based principally upon the writer’s studies among the Mesozoic Mammalia, and, with some additions, upon Prof. Cope’s numerous essays upon the tritubercular type in the Tertiary Mammalia.! Four propositions may be laid down for discussion :— (1.) That trituberculy was acquired during the Mesozoic period, in a series of stages beginning with the single cone and attaining to the primitive sectorial type in the Jurassic period. _" Professor Cope’s essays abound with discussions and notes upon the origin and succession of the tritubercular type. (See collection, in ‘ Ori- gin of the Fittest”). He has outlined the transition from the single cone to the tritubercular crown ‘(p. 347); the tubercular sectorial (p. 246) ; the quadritubercular type (p. 245 and p. 359) ; the Spalacotherium molars as a transition to the tritubercular (p. 259). The acquisition of the superior and inferior quadritubercular molar (p. 361). The predic- tion of the discovery of Carnivora with triconodont molars (p. 365), and _ Of the simple tritubercular type in both jaws (p. 362). 1070 Evolution of Mammalian Molars. (2.) The majority of Mesozoic mammals showed trituberculy in some of its stages. Present evidence goes to show that the remain- ing, or aberrant types, if such existed, did not persist. The majority of the persisting forms of later periods were derived from the forms, with simple tritubercular molars, of earlier periods. It follows that _trituberculy was an important factor in survival. (3.) The definite homologies of the primary and to some degree of the secondary cusps in the upper and lower molars can be estab- lished. (4.) The mode of succession of tooth forms favors the kinetogen- esis theory advanced by Ryder and Coope. There are three general observations to be made:— First—In attempting to complete the history of each of the cusps, we naturally find that the paleontological record is not suffi- ciently perfect to admit of our following a certain type alonga single phylum back to the primitive type. We must at the outset pro- -ceed upon the principle of similar effects, similar causes. For example, since the history of the development of the intermediate tubercles in the superior molars of the Lemuroidea (Pseudolemu- roidea, Schlosser) is perfectly clear during the Wasatch and Bridger epochs—it is safe to infer that the intermediate tubercles of the Ungulate molars, which are fully developed in the underlying Puerco, had the same history. Second.—There are in each period Aberrant types which embrace either incomplete or degenerate tri- tubercular stages, i.e., a high specialization in which the past rec- ord is obliterated, or, finally, stages in non: tritubercular lines of development. Third.—In the parallel evolution of trituberculy in different phyla we find that the progression is by no means uni- form. In every geological period in which the fauna is well known _we observe progressive genera which outstrip the others in reaching a certain stage of molar development, contrasted with persistent typ® which represent arrested lower stages of development, while between them are the central types which represent the degree of evolution attained by the majority of genera. The latter may be said to constitute the stage which is characteristic of the period. 4 _ The Stages of trituberculy may now be defined as seen in different — types in their order of succession :— Evolution of Mammalian Molars. 1071 I. Haplodont Type (Cope)! A simple conical crown. The fang usually single and not distinguished from the crown. This type has not as yet been discovered among the primitive Mammalia. A Protodont Tub.

There is some ques- tion as to the advantage of distinguishing this as a type, for it stands intermediate between types I. and III. Example, Dromotherium of the American Triassic. II. Triconodont Type (Osborn, op. cit., p. 242). The crown elongate, trifid, with one central cone and two distinct lateral cones The fang double. Example, Triconodon. II. Tritubercular (Cope). The crown triangular, surmounted by three main cusps, the central cone placed internally in the upper mollars and externally in the lower molars.

This type is rare in its primitive condition as above defined. e upper and lower molars are alike in types I. and II.; in type III. they have a similar pattern but with the arrange- ment of the homologous cusps reversed. These types are all primitive. In the following sub types, the primitive trian- gle forms the main portion of the crown, to which other “secondary” cusps are added, the homologies of which in the upper and lower molars are somewhat doubtful. Parallel and with an intimate relation to the addition of the secondary cusps, is the division of the tritubercular into a secodont and bunodont series, according to the assumtion of a purely cut- ting or crushing function.

The molars of the contemporary Microconodon (fig. 2) also have unpaired fangs, but distinctly trifid crowns, with the anterior and the posterior cusps, or para and metaconids, upon the slopes of the protoconid. This Triconodont type reappears, with the addition of a cingulum and paired fangs, in Amphilestes (fig. 3) and Phascolotherium (fig. 4) of the lower Jurassic and persists in Tricondon (fig. 5) of the upper Jurassic. In this succession we observe especially the relative subsidence of the protoconid and upgrowth of the para- and metaconids. Contemporary with -Amphilestes is the classical genus Amphitheriwm (fig. 6). A recent examination of the type Specimen by the writer revealed the very interesting fact that the molars of, this genus are probably of the primitive tubercul- _ ar- sectorial types,—the oldest known example. Only the para- cone and metaconids and hypoconids have been observed heretofore, but one can see the tip of the main external cusps between the former pair. This pattern is repeated, with a considerable elevation of the heel, in Peramus of the upper Jurassic.’ Neither of the two foregoing are of the primitive heelless tritubercular type which is apparently found in Spalacotherium also upper Jurassic, and in the nearly related if not synonymous Peralestes, Plate XXV. Contemporary with the above, are numerous genera of the Stylodon order; among these, Asthenodon is of ' This genus includes also Septocladus dubius Owen, and Spalaco- therium minus Owen.

No bnunodont forms are known—they were probably developed during the Cretaceous, for a few are found well developed in the Puerco. In the Sectorial series many of the types do not widely depart from those seen in the Jurassic, but the Bunodont series are universally characterized by the initial or advanced development of the proto- and metaconules in the upper molars and the apperance of the Entoconid upon the inner side of the hypoconid below. The principles governing cusp development.—It is remarkable to note in how many particulars the actual succession of molar devel- opment in the Mesozoic period coincides with the theoretical scheme of origin of trituberculy proposed by Cope! and supported by Wortman ? several years ago. At that time Spalacotherium and -the genera now embraced under the Triconodontide were the only Mesozoic mammals whose molar structure was fully known, and the views of these authors were partly speculative and partly deductive from recent dental anatomy. Two hypotheses may be advanced to explain the evolution of the ritubercular type. The first is that the type has been acquired by the selection of accidental variations in the production of new cusps ” and modelling of old ones. The second is, that the interaction of the upper and lower molars in the movements of the jaws has resulted in local increase of growth at certain points, resulting first in new cusps, then in a change of position and of form in the _cusps. Both hypotheses are open to numerous objections and are by no means mutually exclusive, but the whole subject is so com- plicated as to require a separate treatment. The balance of evi- dence in tritubercular evolution seems to favor the second oF _ kinetogenesis theory—as apparently witnessed in two laws of cusp development. I. The primary cusps first appear as cuspules, or minute wee: 1“ The Evolution of the Vertebrata Progressive and Retrogressive,’ American Naturalist, April, 1885, p. 350. n 1886 ae The Comparative Anatomy of the Teeth of the Vertebrata, p. 418, Evolution of Mammalian Molars. 1075 at the first peints of contact between the upper and lower molars in the vertical motions of the jaws. II. The modelling of the cusps into new forms, and the acqui- sition of secondary position, is a concomitant of interference in the horizontal motions of the jaws. The second law applies especially to the evolution of the molars after the acquisition of the tritubercular stage, and has been ably proposed and supported by Ryder,! principally in its application to recent types of teeth. The first, although not heretofore distinctly formulated, is partly founded upon facts and principles advanced by Cope, and applies chiefly to the stages which have been discussed in this essay. During the Homodont mammalian or sub-mammalian molar Stage, the jaws were probably isognathous and the simple cones alternated as in the Delphinide (fig. 1). The first additions to the protocone appeared upon its anterior and posterior surfaces. The growth of the para- and metaconids involved anisognathism,” for we find in the later triconodonts that the lower molars closed inside of the upper (Zriconodon, fig. 2). There are several transition forms such as Tinodon and Menacodon between the primitive tri- conodont type and Spalacotherium, and it has been assumed by Cope and the writer (op. cit., p. 243) that the para- and metaconids were first formed upon the anterior and posterior slopes of the protoconid and then rotated inwards, but it is also possible that they were originally formed upon the inner slopes. In the complemental formation of the upper and lower triangles the jaws remained nearly isognathous (fig. 4). There is no evidence as to the origin of the hypoconid, which as a rule preceded the hypocone, as it was developed very early. In the Stylacodontide, Phascolestes, Amblo- wi On the Mechanical Genesis of Tooth Forms.” Proc. Phila. Acad., PE ea by Ryder (op. cit., p. 45). “So as not only to indicate respectively parity and disparity in transverse diameter of the crowns of the upper and lower molars, but sad re parity or disparity in width transversely, from outside to outside,” It is clear that in the homodont bone oe with the teeth simply piercing the food, the greatest comminution (of the food) is effected by isognathism ; in the triconodont stage, the jaws must be anisognathous to close upon each other, but the tritubercular stage admits a return to isognathism by the alternation of the triangles. 1076 Evoiution of Mammalian Molars. therium, ete., the crowns rapidly increased in transverse diameter (fig. 7) and, in some genera, they (Kurtodon) so far lost the tritu- bercular aspect that, but for the connecting form Asthenodon (fig. 6), we might hesitate to place them in this series. The key to the further evolution of the crown is seen in the bunodont series during the lower Eocene period. The superposition of the lower and upper molar patterns brings out many interesting facts. First, even in the complex crowns of the bunodont molars the primitive triangles retain their primitive alternating arrangement. Second, the jaws are somewhat anisog- nathous. Third, in support of the first law of cusp development, we observe that the protoconule and metaconule are developed at the points of contact with the ridges which extend from the hypo- conid, and, secondly, that the hypocone appears at the point where the paraconid abuts against the protocone. It follows from a com- - parison of numerous species of Pelycodus and Miocloenus that as the hypocone develops, the paraconid recedes, as first observed by Cope; a fact difficult to reconcile with the kinetogenesis theory. In this manner the inferior primitive triangle is broken, as the upper molars develop into the sextubercular and the lower into the quad- ritubercular type. The complemental development of the upper and lower molars in the known genera of successive horizons 18 approximately displayed in the subjoined table. i he Eocene list of genera will be greatly reduced, especially m the Tritub.-tuberc-.sectorial type, when the upper and lower Jaws are found associated, and it must be clearly understood that the sub-types a, b,c, in the above table, are very closely related by transition forms. In fact, in the carnivorous forms, the extreme secodont and bunodont types are frequently seen side by side, as 0 the first and second inferior molars of Didymictis. The chief dis- tinction between these two series is the greater development of the secondary cusps and the almost invariable loss of the paraconid y the latter ; this is effected by the broader surfaces of contact in the bunodont crowns. In the secodont series, on the other hand, the development of the secondary cusps is subordinated, and th conid is almost invariably suppressed.’ 1 See Cope: “ Origin of the specialized Teeth of the Carnivo Naturalist, March, 1879. e meta- ra.” Am’ J - \ \ a WS * . 1.—Merycocherus macrostegus Cope. : $ ; Fic. 2.—Merycochærus superbus Leidy.

The Relation of Trituberculy to the Persistence of Mammalian Phyla.—The above table shows somewhat indefinitely, but none the less positively, the general progression of the Mammalia, to and from the primitive tritubercular type. As already stated, even with our present very limited knowledge, certain stages appear to have been characteristic of certain periods, as follows: the triconodont in the lower Jurassic; the primitive tritubercular and tubercular sectorial in the upper Jurassic; the secodont and bunodont sub- types of trituberculy, predominated in the Puerco ; in the Bridger, the Perissodactyl ungulates had mostly passed beyond into the lophodont and symborodont types, and the Artiodactyls were approximately in the stage of sub-types c; but the Lemuroidea, Creodonta, Insectivora, etc., were, almost without exception, tritu- bercular. | There can be little doubt that, parallel with the tritubercular forms, in each period, there were aberrant or degenerate types, but it is difficult to determine which these are. Many Mesozoic types, which the writer formerly considered aberrant, have now proven to be tritubercular The upper Jurassic genera included under the Dicrocynodontide (see Marsh, Amer. Journ. Se., April, 1887, p. 338) are apparently aberrant. There are several degenerate types among the Puerco and Wasatch Creodonts, such as Dissacus and Mesonyx. But there is a striking proof of the superiority of the tritubercular molar in the fact that, according to our present know- ledge at least, the Jurassic mammals possessing aberrant or degen- erate molar types did not persist into the Puerco, nor did such types in the Puerco persist into the Bridger. There is some doubt as to the persistence of the sub-tritubercular stage; the writer pre- viously considered the Thylacinus molars as triconodont ; but Mr. Lydekker has called attention to the probability that the metaconid has disappeared and been replaced by a heel as in the sectorial teeth of the Carnivora. The disappearance of the degenerate types ney be attributed to the general principle that rapid specialization and loss of parts leads ultimately to extinction, by depriving the anima of the means of adaptation to new conditions, or surroundings. * See ‘‘ Additional Observations upon the Structure and Classification _ Of the Mesozoic Mammalia.” Proc. Phila. Acad., Nov., 1888. see : The Artiodactyla. 1079 The mechanical superiority of the tritubercular type, over every other has been repeatedly demonstrated in its plastic capacity of adaptation to the most extreme trenchant and crushing functions. THE ARTIODACTYLA.! BY E. D. COPE. p= Artiodactyla is the suborder of the Diplarthrous Ungulata in which the astragalus articulates with the second row of tarsal bones by a ginglymus or hinge, and in which the third and fourth toes are equally or subequally developed.? It includes the Most highly modified of the Mammalia, whether we regard the organs of locomotion or of digestion. The antelope and deer illus- trate the greatest speed to which the mammal has attained. Their extraordinary apparatus for the digestion of vegetable substances which contain but a small percentage of nutritious proteids, has given them an extraordinary advantage, so that they are after the rodents, the most abundant of their class, in spite of the persistent persecution of the carnivorous species. They attain in the genera Giraffa and Bos the largest dimensions in the class, excepting only the Proboscidia. The Artiodactyla make their first appearance in the early or Wasatch Eocene in the genus Pantolestes Cope. A genus exists at a corresponding horizon in Europe. -No other genus of the sub- order appears with it. Its representatives steadily increase in numbers in the succeeding Bridger and Uinta epochs in America, and in the Calcaire grossier and Gypse of Europe. Some of these, €g., the Anoplotheriide of Europe, diverge from the line of suc- cession, while others, e.g., Xiphodontide, are clearly ancestors of later forms, In America, the Pantolestide appear as ancestors of the Camels especially. I now give a synopsis of the families of the suborder and their phylogenetic relations. I Superior molars tritubercular (Pantolestoïdea). Molars bunodont; four digits sss... Pantolestidæ.

The six families with living representatives are the Suide, the Tragulide, the Camelidæ, the Moschide, the Cervide, the Giraffidee, and the Bovide.! Thus none of the primary divisions, I and II, have recent representatives. But few of them in fact (some Cænotheriidæ and Anthracotheriid) survived the Eocene epoch. Division III is, on the other hand, characteristic of Miocene and recent time, except that some specimens of Gelocus of the Tragulide have been found in Upper Eocene beds. Several genera of Tragulide, with Elotherium and Poébrotherium and Oreodon, belong to Oligocene - beds. Tubercular or bunodont molars are of prior age to selenodont molars, phylogenetically speaking. Of the former, the tritubercular type, it has been already shown, is ancestral to the quadritubercular type. Pantolestide are then clearly ancestral to all known Artio- dactyla, and are themselves probably the descendants of the lost Amblypoda Hyodonta, whose existence I have anticipated on hypo- thetical grounds. Of the remaining families which are constructed on the quadritubercular basis, there are two types, as represented in divisions II and III of the preceding table. The intermediate or fifth lobe is especially characteristic of Eocene Artiodactyla. The intermediate tubercles exist in the Pantolestidie, and one of them is preserved in the families of division II ; but in group 4 it is the posterior one, and in group AA it is the anterior one. In the Suide and Hippopotamidz, which are permanently bunodont, the intermediates are either lost or so divided as to lose their distinctive ' Antilocapra is sometimes separated from the Bovidee as the type of a family, because it is said to sometimes shed its horny horn-sheath. This character, were it really normal, has no significance sufficient for the establishment of a family division, 1082 The Artiodactyla. character. In Elotherium traces of both the intermediates are visible, but they are obscure. The genetic relations of the families with five lobes to those with four are supposed by Schlosser to be direct and ancestral. This looks probable in the case of the Mery- copotamidæ of the latter group, which has inferior molars like those of Hyopotamus of the former group. Whether the remaining families of division III AA (see table) (four-lobed) came off from the families of division ITI (five-lobed) is uncertain. It is probable that the fifth and sixth (or intermediate) tubercles were present in all primitive Artiodactyla, but they may have been lost, as in the Suidæ, in the bunodont stage, which gave origin to III AA, so as to be wanting from the earliest four-lobed selenodont ancestors. Of the two types of II (Anthracotheroidea) the division Æ is supposed by Schlosser to have been the ancestor of the true selenodonts (III 44), but excepting in the case of Merycopotamide, this has not yet been demonstrated. Scott suspects with reason that the quinquetubercular Protoreodon is the ancestor of the quadrituber- cular Oreodon. Leaving this debatable question, I refer to the family of the Anoplotheriide. The remarkable structure of the feet discovered by Gervais, and shown by Schlosser to belong to this family distinguishes it at once from all families of this and all other orders. | ul The second digit is well developed in both | i feet, and stands inwards at a strong angle to ` the other toes. A rudimental fifth is present ji in the manus, but not in the pes. The latter i * is therefore tridactyle. The third and fourth i digits are equal in the pes, but the third er” a U ceeds the fourth in the manus, giving an entirely SG perissodactyle character.

Gaudry, Enab einan $ he origin of the Anop- du Monde Animar remarked by Schlosser, the orig H lotheride is entirely obscure as yet, the only ancestor yet kno a being the Pantolestida. It is probable that some unknow member of the Anthracotheroidea, which had bunodont teeth, may The Artiodactyla. 1083 form one of the missing links. Cebochcerus offers the proper type of dentition, and the number of toes (four, Schlosser) is also appro- priate, but whether there are any structural obstacles to its being ancestral to the Anoplotheriidz I do not know. Anthracotheriidz can be properly supposed to have descended from a type of Pantolestide with well-developed lateral toes, by the addition of the fourth tubercle, and the loss of the posterior in- termediate ; while the Dichobunide have had the same origin, the posterior intermediate cusp being preserved. The Xiphodontide may be supposed to have come off from the Anthracotheriide by the usual process of diminishing the lateral digits and developing both sets of crescents in both superior and inferior molars. This family carried the specialization of the five tubercled type farther than any other. The Suoidea have come off from the Pantolestoidea by the addi- tion of the fourth (posterior internal) tubercle to the superior molars. Some genus with better developed lateral (second and fifth) digits than Pantolestes must have been the ancestor. Such a form will be discovered. It has been already anticipated by Schlosser,} It is a circumstance confirmatory of the view that the Cameloi- dea and Bodidea are descendants of the Anthracotheroidea rather than of the Suoidea, that no genus of the latter superfamily shows the least tendency to assume a selenodont structure of the molars. It is therefore not unlikely that the two groups named may have . had the history of the Merycopotamoidea already referred to. They did not probably come from the Merycopotamoidea themselves, since the geological age of the latter is too late. Of course, how- ever, members of this group may be yet discovered in earlier formations. _ The problems of the phylogeny of the remaining groups are less difficult, and have been largely solved by the investigations of Kowaleysky and Schlosser. Tragulide have been derived from Oreodontidæ with simpler premolar teeth than the typical forms, (¢.9., Dorcatherium and Lophiomeryx). In turn they have given origin to primitive Bovide (Cosoryx) through Gelocus, which have then branched off into specialized Bovide on the one hand, and 1 Morphologisches Jahrbuch, 1886, p. 77. 1084 The Artiodactyla. Cervide on the other. The Poébrotheriide have originated, from ‘some family with diminished lateral digits, perhaps the Dichobuni- de, various intermediate genera being yet unknown. They are the direct ancestors of the Protolabidide, the camels, and the Eschatiid. These relations may be expressed in the following e :— Bovidæ. Eschatiidæ. | Cervidæ. Camelidæ. Moschidæ.

Of PANTOLESTIDÆ but one genus is known. The premolars are all simple in the upper jaw, exċept the fourth, which has one external and one internal tubercle. Six species are known from the Bridger and Wasatch Eoeines of N. America. (Fic. 2.) The structure of the premolars in Anoplotherium is complex for so primitive a type, and the third superior has an internal crest as well developed as in some of the Boöïdæ. To the ANOPLOTHERI- .DÆ are referred, besides Anoplotherium, Diplobune of Fraas and Dacrytherium, Mixtotherium and Mixochærus of Filhol. But the structure of the feet of the latter genera is unknown. In Mixto- therium the fourth premolar is more, and the others less complex than in Anoplotherium. (Fres. 1, 3.) f The known genera of DicHosunip&® are Dichobune of Cuvier, with Spaniotherium and “Dilotherium of Filhol, in which{the inte The Artiodactyla. 1085 mediate tubercles are less developed than in Dichobune. They are related to the twe selenodont genera of CÆNOTHERIIDÆ, Cæno- therium and Muillactherium., The latter differs from the former in the absence of the intermediate crescent from the last superior molars. The species of Cenotherium differ in the absence or pres- ence of ashort diastema in the dental series, and in its position in the lower jaw, whether behind the first or secondpremolar. (Fic. 4.) The Dichobunid bunodont genera are ancestral to the Czenothe- riid selenodont genera in the following fashion :— Jeenotherium. Muillactherium. | Spaniotherium. Dilotherium. Diehobuune. This family terminated with the selenodont genera, which, as hlosser remarks, left no known descendants. THE ANTHRACOTHERIID# present but few varations. Four genera are known, which differ as follows :— Entirely bunodont ; no diastemata ; canines developed. Cebochcerus ery. Cusps of superior molars little flattened ; diastemata ; canine large. eropotamus Cuv. Cusps of superior mòlars flattened ; no diastemata ; canines large. Anthracotherium Cuv.

The three genera last named cannot, as Schlosser remarks, be related in direct lines, but through common ancestors ; as may be shown thus :— Hyopotamus. j *1/ / f / Anthracotherium. Choeropotamus, Cebocheerus. 1086 The Artiodactyla. All the known species of this family are Old World excepting the single Hyopotamus americanus of Leidy. The genera Ceboch- ærus and Chceropotamus are from the Eocene, while the remaining two genera are of Miocene age. Some of the Anthracotheriums equaled the Rhinoceros in size,and were powerful beasts, well z armed with formidable canine teeth. The species of Hyopotamus were on the other hand, of inoffensive char- acter and had narrow compressed muzzles like the Jamas, but more gen- erally elongate. The ancestral genus is bunodont, without diastemata, and with well- developed canines. The hypothetical genus (1) is selenodont, with short diastema, and well-developed canines. The certainly known genera of the KIPHODONTIDÆ are four, which differ as follows :— Molars bunodont; diastemata; ca- nines large......

Protoreodon S. and O. Cryptomeryx Schl. probably belongs here. The relations of these genera are clearly somewhat like those of the preceding family. The bunodont condition of the molars of Rhagatherium is primitive, while its diastemata are the reverse: The continuous dental series of Xiphodon is primitive, while the detailed structure of the molars is advanced. These relations may be thus shown :— The Artiodactyla. 1087 Xiphodontotherium. Protoreodon. Xiphodon. Rhagatherium. S lz The hypothetical! genus 1 is simply a bunodont without diaste- mata, and with well-developed canines. The genera of this family are Old World, except Protoreodon, which is North American. The Xiphodon gracilis Cuv. is one of the most abundant species of the Gypse of Paris and its equiva- lents. The restoration of Cuvier shows it to have been a graceful animal, with slender legs and neck. In Prootreodon S. and O. we first see the enlargement of the fourth inferior premolar (first olim) to function as a canine, which afterwards became such an important character of the Oreodontidæ. Probably two species are known, both from the Uinta formation of Utah; the? “type, P. pavous Scott and Osborn, IEN about the size of a raccoon. aT EREL EA VA e The Hippopotamidæ embraces a considerable variety of genera, which are spmetimes arranged in separate families.

From Lydekker, ` The genera of Hippopotamine are all Old World. While a single living species represents each of the genera Hippopotamus an Chceropsis, there are several extinct species of Hippopotamus and Hexaprotodon. ‘hese are chiefly confined to the Upper Miocen? skull, from PLATE XXVIII. Cyclopidius emydinus Cope. The Artiodactyla. 1089 of India, but a species has been found in Algerian deposits, and a large form, Hippopotamus major, is abundant in the Plistocene of Southern Europe. Ofthe Hyotheriine the most generalized form, Hyotherium, is represented by several species in Europe and India’ In its characters it is the most primitive of the family excepting in the weakness of the canine teeth. It is nearer the ancestral genus of the family than any that is yet known. In Bothrolabis we have a distinct approach to Dicotyles, of which it is probably the ancestor. Four species from the John Day or Middle Miocene of Oregon are known. They were of the sizes of the existing peccaries. The genus Platygonus embraces extinct species of North America and Mexico. P. vetus Leidy has left remains in the Pennsylvania Bone Caves. It was larger than the white-lipped peccary. P. alemani Dugés has been found in Mexico. Several extinct species of Dicotyles are known, from the North American Plistocene and ? Pliocene. One of them, D. nasutus Leidy, has a more elongate muzzle than any of the recent species. . The Elotheriinse embrace the oldest known forms of the family, dating in geological time from the Lower Miocene or Oligocene, and terminating with the summit of the middle Miocene. But one genus is certainly referable here, the Elotherium of Pomel; but a second, Tetraconodon Falconer, may belong in the same group. As the feet of the latter are unknown, the affinities cannot be yet determined. It differs in the inferior dentition from Elotheriam by the huge size of its premolar teeth. Elotherium is represented by species over the Northern Hemisphere. The E. magnum is the only one known from Europe. It was larger than the domestic hog. The Æ. mortoni Leidy of North America was about the size of that animal. Its remains are common in the beds of White River age. It was accompanied by a huge species, the E. ramosum Cope, which has a skull as large as the Indian Rhinoceros. In all the species of this genus the mandibular ramus has two osseous projections, one opposite the symphysis, and the other well behind it. These are represented by wattles in old males of the recent hog. In the E. ramosum these tuberosities become processes, and the an- terior ones especially are so long that when the chin was stretched, hog-like on the mud, it was raised well above the surface, allowing the passage underneath of water or of small animals.. In the John 1090 The Artiodactyla. Day beds of Oregon another species of this genus is found, the Æ. imperator of Leidy, which was little inferior in dimensions to the E. ramosum. The greater part of its skeleton is known. The pigs (Surpm) are modified and specialized descendants of some form allied to Paleocherus. Chronologically speaking they are of rather modern origin. The genera are as follows: — (a) Molars and superior incisors not reduced; the former not covered with cement; superior canines recurved (Suinz). Molars with cusps united into transverse crests, Listriodon Meyer. Molars with four much plicate tubercles on each .

FIG. 5.—Coloreodon ferox Cope, skull from the John Day Miocene of Oregon, one- half natural size. Listriodon and Hippohyus are the only genera of Suide which are extinct; but the extinct species of Sus are more numerous. In _ Listriodon the molar teeth are so tapir-like as to have led to its being placed in the Perissodactyla. When the skeleton was ob- The Artiodactyla. 1091 tained, it was found to be artiodactyle, as suspected by Kowalev- sky. One species, L. splendens, has been found in the Middle Miocene of Western Europe. Hippohyus C. and F. is known from the Indian Siwaliks. A genus of probable affinities to it, founded on teeth only from Asiatic localities, is the Sanitherium of Schlag- intweit. Some of the extinct species of Sus were of larger size than the existing hog, as the S. giganteus of the French Miocene, and the S. erymanthius of Pikermi, Greece. The S. silvanius Hodgson, a recent Indian species, is not larger than a small dog. The phylogeny of these two bunodont families is nearly as follows, although the absence of intermediate types renders the final deter- mination as yet impracticable. The main features may be how- ever foreshadowed. The most generalized form is Paleocheerus, since its dentition is in all respects the most simple, while it pre- serves the full number of teeth. An unknown form resembling it, but with well-developed canine teeth, may have readily given origin to the Dicotyline line on the one side, and Sus and its immediate allies on the other. Babirussa is another derivative from the same centre. Phacochcrus may have come from some ally of Sus, since it carries to a great extreme the peculiarities of the latter genus. The ancestry of Hippopotamus is less easily determined. Its im- perfect distal metapodial keels, which only exist on the posterior face of the condyle, bespeak for it an ancient ancestor. Its molar type is merely a complication of the quadritubercular, while the characters of its canines are an exaggeration of those of the prim- itive forms already mentioned. Several other genera, as Dicotyles and Sus, display. the decumbent incisors which prepare the way for the remarkable straight digging incisors of Hippopotamus. The genus Hexaprotodon eases the passage backwards. These relations may be expressed as follows :— Cheeropsis. Phacocheerus. Platygonus. Hippo, otamus, Dicotyles, Cheenohyus. Hexaprotodon. Babirussa. Sus. Bothrolabis. f f \ vs vai eal \ J e \ PA P A port ae ; x \ ff J A * Hyotherium, 1092 The Artiodactyla. AT The MERYCOPOTAMIDÆ embrace but one genus, Merycopotamus: C. and F., which is a form of considerable interest. Its superior molars display the simple quadriselenodont type of the later fam- ilies, but in the lower jaw the primitive condition of but one series of crescents still remains. Several spe- cies are known, all from the upper miocene of India. The OREODONTIDZ is the prevalent type of Arti- odactyla during Miocene time in North America. Their characters are as fol- lows :— Dentition : superior incisors present ; molars selenodont. Cervicals with brarterial canal. No alis- phenoid canal, Ulna and radius, and tibia and fibula distinct. Metapodial bones four on each foot, with incomplete distal troch- lear keels.

The presence of the pollex observed by Scott in Oreodon proves that it must be referred to a five-toed common ancestor with Dorcatherium. The enlarged bullæ are added in Eucrotaphus, and the codssified premaxillaries in Merycochcerus and Merychyus. The latter commences the facial vacuities, which _ reach such huge proportions in Leptauchenia and Cyclopidius. The loss of the incisor teeth from both jaws, and diminished size, indicate that decadence is going on in Cyclopidius, but the last term is reached in Pithecistes. Here not only incisors but a premolar disappears. This family, once powerful in numbers, size and strength, disappeared with the Upper Miocene period in North erica, These relations may be thus displayed. A common ancestor with Dorcatherium is assumed. This will be a genus like Protoreodon S. and O., but without the caniniform inferior p. m. i of 1094 The Artiodactyla. that genus, and probably with the fifth crescent of the superior molars.

During the White River epoch droves of Oreodon culbertsoni inhabited the swamps, and the small O. minor was abundant. Several forms, perhaps species, coe with these two. During the John Day epoch Oregon and adjacent regions were overrun by the Eucrotaphus pacificus, and the large and formidable Meryeochoerus superbus (Plate XX VI). Ata still later date, in the Ticholeptus epoch, the species of Cyclopidius were scarcely Jess abundant. All of these forms were the prey of num- erous Carnivora, mostly false sabre-tooth or half sabre-tooth cats, The Artiodactyla. 1095 of the family of the Nimravide. The large Merycocheeri possessed the means of making a formidable defense, but the Merychyi of later age were of decidedly less vigorous mould (Plate XXVII). The species of Leptauchenia and Cyclopidius were probably aquatic in their habits. The species of the last named genus (Plate XXVIII.) had produced tympanic bones like the hippopotamus for the insertion of ears that projected above the water, while the eyes are partly vertical to permit of vision without much exposure of the head. The nostrils are at the extremity of a sharp muzzle like the snapping tortoise to premit of breathing without exposure of the face. The object of the remarkable facial vacuities in this genus and Leptauchenia is unknown. It may have per- mitted the attachment of an inflatable integument like the nasal hood of the hooded seal. In Pithecistes the incisor teeth have disappeared, and the short deep jaw, the only part which is known, resembles in its codssified symphysis, that of a monkey.

Davis’s TEXT-BOOK or Biotocy.’—Of this book of 462 pages a little more than one-third is devoted to plants, and hence prop- erly to be noticed by the present reviewer. Unlike many works on biology, this is in fact two independent books printed and bound together. Each part has its separate bibliography and index-glos- sary, and there are no references from the one part to the other. One is puzzled, indeed, to see any good reason for calling the book one on biology: it is rather a botanical and a zoological book bound together. art I. takes up in succession Saccharomyces, Bacteria, Mucor - and Penicillium as representing the fungi; Protococcus, Spirogyra, Fucus, Chara and Nitella, representing the Alge; Funaria and Polytrichum for the Mosses; Pteris and Nephrodium (Aspidium) for the Ferns; Pinus for Gymnosperms, and a “typical Flowering plant” for the Angiosperms. Following these are short chapters on Comparative Vegetable Morphology and Physiology, and the Classification of Plants. — The book is not a laboratory manual at all, but rather a text-book to be read or studied. The author himself, in his preface, after refer- ring to the several excellent works on practical biology which have appeared within the last few years, and the want of a comprehen- sive work on theoretical biology, says that “the object of the pres- ent text-book is, therefore, to supply such a systematic and simple exposition of the subject within small compass as, it is hoped, will be found helpful, both to those who are studying alone and to those who have the advantage of guidance in their work.” Theoretical biology is, then, the scope of the work, and in this it stands in sharp ab with Huxley and Martin’s well-known laboratory hand- The treatment of Saccharomyces—the Yeast Plant—may trate the style of the book.

Bessey. MIcroscopicAL PHysioGRAPHY OF THE Rock-MAKING MIN- ERALS. By H. Rosenbusch. Translated by Joseph P. Iddings. New York: Wiley & Sons, 1888. Illustrated by 121 wood-cuts. and 26 plates of photomicrographs. xiii. and 333 pp.—With the excellent translation of Prof. Rosenbusch’s book, presented us by Mx. Iddings, there can no longer remain an excuse for the continued neglect of microscopical petrography by our colleges and advanced schools. . Heretofore the immense mass of facts relating to the microscopical properties of minerals which have accumulated within the past ten or fifteen years, have been beyond the reach of those who are not familiar with the German language. The excellent compendium of Prof. Rosenbusch has not been available to English- speaking students on either side of the Atlantic. It is a matter for congratulation that the first translation of this book should have been made into English by an American Scientist, and by one who has proven himself so capable of undertaking the task as has Mr. The translation is at the same time an abridgement. The six hundred and sixty-four pages of the original have been reduced by the translator to three hundred and thirty-three. This has been accomplished by omitting the bibliography (which occupies eighty- eight pages in the original), by excluding the purely historical Portions, and by restricting within narrow limits the discussion of the anomalous action of certain minerals in polarized light. Since these matters would be of little value to any but the advanced student in the subject, and since such a one must of necessity go to the original sources for his information, Mr. Iddings has done well in deciding not to confuse the mind of the beginner with too much of the unessential. So far as a hurried reading of the book allows One to judge, everything essential to the study of the optical prop- erties of the rock-forming minerals has been retained, and in many cases additions have been made to the description of those minerals 1098 General Notes. which have been found to be much more widespread as constituents of rocks than was supposed when the German edition was published three years ago. A further reduction in the size of the book is effected by a rather free translation, by which an entire sentence is sometimes reduced to the position of a short qualifying phrase, and by the omission of certain tables of refractive indices, but more especially by the exclusion of the references to the occurrences of the various min- erals in rocks of foreign localities. To compensate for the latter loss, notes on American occurrences have been copiously inserted. The style of the language used is clear; the expressions are forcible; and, better tnan all else, the reader of the translation may rest assured that he is getting the exact thought of the author of the original. Not only is Mr. Iddings to be commended for his careful trans- lation, but Messrs. Wiley & Sons are likewise to be congratulated on producing a work of such a pleasant appearance as the book ore us. The only fault that can be found with the volume is its price. It would seem that in view of the fact that the translation will - meet with a ready sale in England and America, its price might have been placed at such a figure as to enable every one taking a course in geology to indulge in the luxury of a few weeks work with the beautiful objects in rocks revealed to our eyes when aided by the polarizing microscope.— W. S. B GENERAL NOTES. GEOGRAPHY AND TRAVEL. NANSEN’S GREENLAND EXPEDITION.—The last mail Bs Norway brings more informajion about the Nansen expedition to the interior of Greenland. The expedition consisted of the following named daring men, under the leadership of Dr. Frithjof er conservator of the Bergen Museum ; Lieut. Olaf Dietrichsen, F Otto Sverdrup, Christian C. Trana, Ole N. Ravna, and Samuel 7 Batto, all especially selected men, strong and healthy in bocy mind and good “ski-runners.” “ Ski ”are the snow shoes ext used in Norway for travelling over the snow fields of that country. The party left Norway on May 2; travelled by steamer as far as Iceland, where they arrived in the middle of June. From Ice me the whaler Jason brought them over to Greenland, and of Hi Geography and Travel. 1099 17th of July left them on the drifting ice with the land in sight some few miles distant. From that time until they could reae the inhabited west coast of Greenland communication with the rest of,the living world would be an absolute impossibility. A stretch of 450 miles, never traversed by man, lay before them ; they had their Norwegian ski, provisions fortwo months, and necessary in- struments for making observations, and they started for the shore. They had to make their way across the glaciers in two months or die. Not before next summer can we haye a complete report of the journey ; till then we must, with the information we get from two hurriedly written letters which, by mere accident, came over in the last vessel from that region this year. The letter from the mate Sverdrup to his father is given below: GODTHAAB, Oct. 4, 1888. “Yesterday, after sixty-four days’ journey from the east coast, we arrived here all safe. The landing was more difficult than we had calculated. The drifting ice upon which we stepped when leaving the whaler was moving very rapidly toward the south and off from the shore, and it took us twelve days to reach the shore. In that time we had drifted nearly 100 miles. As soon as we had terra firma under foot we started northward along the coast, looking for a place where it would be possible to ascend the solid inlandice, After another twelve days’ search we finally found such a place, made our_ way up without very great difficulty, and on the 16th of August we commenced our westward march. We at first laid our course for Christianshaab (a settlement to the northwest), but when we had reached an elevation of about 7500 feet a terrible snow storm met us, and we concluded to take a more southerly direction found a stretch of about twenty miles wide free from snow, miles of which was along the edge of a fiord. We brought the tent and provisions down to the shore and built a camp ; further p seemed for a time impossible. Then we made a small boat from, rt of the tent and a canvas When this boat was ready Dr. ansen and I started for this place, and after’ four days’ rowing we arrived here, and were very kindly received by the people. Two boats are now sent to the camp, where we left our companions, to bring them down here. The post-ship has left long ago, but some fifty miles farther south there is a steamer, having been acci- 1100 General Notes. dentally kept back by a breakdown and the storms, now just ready to sail for Copenhagen, and we send two messengers, hoping they will reach the steamer, and perhaps make it wait for us and take us home. We have but very little hope, though, that the steamer will wait, and we shall be compelled to stay here over winter, as this is the last chance this year.” It appears that the steamer did not wait for them, but took the letters and delivered them at Farsund, the nearest ort in Norway. The expedition, consequently, must stay in Greenland through the winter, with the prospect of getting lenty of leisure time, and next summer we shall have a full report of this remarkably daring and interesting journey. GEOLOGY AND PALAONTOLOGY. DESCRIPTION oF NEw AND IMPERFECTLY KNOWN SPECIES OF BRACHIOPODA, FROM THE Devonian Rocks or IOWA —O the Brachiopod Fauna of the Devonian rocks of Lowa, no genus 15, perhaps, so variable as the Genus Atrypa. Many varieties of Atrypa recticularis, of the Iowa strata, are often restricted in their range to certain horizons and localities. For example, at lowa City, Turkey Creek and Roberts’ Ferry, in Johnson county, there occurs in a bed of argillaceous shale a very large and coarse vari- ety of this species, which is not known to appear at any other lo- cality in Iowa, or elsewhere. In some dark bituminous shale at Independence, occurs another variety of the same species, an which is analogous to one of the varieties of the Rockford shales; this form, however, differs from the Rockford shale variety in its very diminutive size. : In the limestone at “Big Bend” of the Iowa river in Johri county, at Independence, Waverly, etc., occurs another well-marke variety. Many individuals of this variety s very large thin wings or expansions, the entire shell having a diameter of from five to eleven centimeters; the body of the shell, however, being often only one-half or even one-third that diameter. i At Littleton, in Buchanan county, is found another very pane variety (a coarse form) whose equivalent is not known to occur & any other locality in the State; its nearest representative, § K known to me, occurring in the Devonian strata at Louisville, 4s A In the Rockford shales occur two varieties, the smaller of per has the front of the shell so strongly contracted as to produce a %15- Geology and Paleontology. 1101 tinct false mesial sinus in the ventral valve. Several other varie- ties of this species also occur in different portions of the State. Not only do the Iowa varieties of this species vary greatly in form, size and surface markings, but they also often differ conspic- uously in their internal structure. Some forms of this species ap- proach so near to Atrypa impressa of the Schoharie Grit of New York, that a strict distinction between them is impossible. Atrypa reticularis of the Iowa strata varies so much in form, size, surface marking, etc., that it could be separated into several forms suffici- ently distinct to have specific names, if the forms were found only distinct groups of rocks. Atrypa hystrix and Atrypa aspera also vary greatly in form, size and internal structure. An interesting feature of the Brachiopod and Polyp faunas of the Devonian strata of Iowa, is the occurrence of quite a number of forms which imperceptably grade into one another; but which forms are seen, in the rocks of other States, to constitute well-marked species. This condition is more particularly noticeable among some forms of the genera Favosites, Cyathophyllum, Atrypa and a few others. spirifera substrigosa, n. sp.—Shell a little larger than medium, somewhat longer than wide, slightly gibbous; cardinal extremities abruptly produced into short rounded projections.

Dorsal valve generally regularly convex, but sometimes flattened on the cardinal extremity; greatest convexity at or a little above the middle; beak incurved slightly beyond the hinge line; mesial fold often not defined; at other times slightly defined; and rarely strongly and sharply defined in front. i Ventral valve gibbous at or above the middle, having twice as great an elevation as the opposite valve; beak generally much ex- tended above the hinge line, but sometimes scarcely ; sharply in- curved, or not incurved; sinus sometimes wanting, at other times shallow and scarcely defined above the middle, and producing a slight sinuosity (at times strongly produced) in front; in some speci- mens with greatly produced hinge lines, the sinus is quite well de- fined nearly or quite to the beak; area large and well defined, prin- cipally confined to the ventral valve, vertically striated; foramen narrow, triangular, extending quite to the open valve, the margins or dental lamellæ often a little projecting.. Surface marked by fine rounded radii; radii about equal to the space between them, “and both are again finely striated in the same direction by microscopic lines, and the whole crossed by fine striæ which give a granulat appearance to the uneven surface”; this feature, however, is not al- ways well shown even in well-preserved specimens. fees The “dichotomising of the radii on the mesial sinus and fold is by no means a constant feature. The internal structure of this shell varies considerably in different individuals. The dental la- mella, which is usually very strong, generally extends to the centre of the valve, and there becomes obsolete; these lamellæ gradually diverge downward and about the ċentre of the valve, between them, is a deep heart-shaped muscular impression, marked by toa to six more or less prominent vertical striæ; the dental lamel æ sometimes extend to the centre of the shell only as slight elevations along the margins of the muscular impressions; the muscular 1m- pressions vary somewhat in size, depth and general form in differ- ent specimens. -t ae _ dn some instances, the interior of the ventral valve is distinct y punctate; cardinal processes of dorsal valve rather large, bifid, an fitting into notches in area of ventral valve.

Shell very variable; semielliptical, subouate, suborbicular, longer than wide or wider again than long; of medium or under medium size; often gibbous in young as well as old specimens; frequently greatly extended on the hinge line, sometimes hinge-line one-third less than the greatest width of the valves below; at other times the hinge-line and valves below are equal, valves subequal ; greatest convexity of the ventral valve at or slightly above the middle; greatest convexity of the dorsal valve at the centre, or a little above. eak of ventral valve strong and usually high, sometimes low; from slightly to very sharply incurved ; the height, strength and curvature of the beak varies somewhat with the age of the animal; central area high, concave, vertically striated ; foramen rather large, triangular, extending to the apex of the valve, the margins or dental lamellae strongly projecting in well-preserved specimens. — Valves marked by very large or small, simple, rounded or angu- lar plications; varying in number from four to thirteen on each side of the mesial fold and sinus, in young as well as adult forms. Mesial fold and sinus marked by from one to six bifurcating pli- cations (in some instances, the plications do not bifurcate, but run out along the margins of the fold and sinus). Usually the mesial fold is strongly elevated in front and more or less well defined to the beak, but in rare instances, even in adult specimens, the fold is not defined, even in front, although the sinus of the opposite valve is well defined to the beak, and produced in front. Mesial sinus more or less well defined to the beak, rather rapidly expanding below, and produced in front into a sharp or broadly rounded extension; bottom shallow or deep, angular or rounded. Surface of specimens, with small or medium-sized plications, marked y very fine strie parallel to the plications; surface of specimens with large, eoarse = oraa marked by stronger and more numer- ous obliquestriz, which unite with each other on thesummit of the pli- cations and centre of the depressions between the plications, thus giving the entire surface a very sharply zigzag striation ; the surface of many specimens are also crossed, in front, by slight lines of growth, Surface of the interior of the valves smooth or marked by ridges, which correspond to the depressions between the plications on the 1104 General Notes. exterior of the valves; dental lamelle in ventral valve slightly produced, sloping abruptly backward and downward, becoming obsolete before reaching the center of the valve; cardinal processes of dorsal valve small, bifid, fitting into notches in area of ventral valve. This is one of the most variable species of Spirifers known to me. The descriptions of this species, and Spirifera hungerfordi, are based upon over one hundred and fifty specimens of each species.— Position and locality: Rockford Shales, Rockford and Hackberry, and Owens Grove, Iowa. There seems to be no doubt but that this very variable species (designated as Spirifera orestes, by H. & W..,) is identical with Spirifera strigosa Meek, as described in Vol. IV., p. 43, of the . S. Geol. Exploration of Fortieth Parallel. This being the case, Meek’s name would, therefore, be considered as having the priority. : Atrypa hystrix var. elongata, n. var.—Shell of medium size, elongate ovate, valves slightly aud nearly equally convex; greatest convexity of the ventral valve slightly below the umbo; greatest convexity of the dorsal valve on the umob. ak of the ventral valve of moderate strength, perforate, scarcely raised above the opposite valve; area closed, surfaces marked by from four to five simple rounded ridges upon each valve, crossed by strong thickened concentric lamine of growth, but which are nut elevated at intervals into spine-like protections. This well-marked variety is known to occur at only one locality, the Rockford Shales, at Hackberry, Iowa. j Atrypa hystrix var. planosulcata, n. var.— This form differs from A. hystrix in the general expression and fineness of the shell. The plications are very much smaller and more numerous, the lamine of growth usually slight and not generally elevated into spine-like projections. These features are very constant in both young an old specimens. i We were at first inclined to consider this form specifically dis- tinct from A hystriæ, but after a large number of them had b secured, it proved that they constituted only a well-marked variety of this species. ; This variety is common throughout the Rockford Shales, and se also the prevailing form which occurs in the limestone which imme- diately underjliesthe shales. We have also secured a very few x. imens from some shales at Roberts’ Ferry, Solon and Turkey Creek, in Johnson county.—Clement L. Webster. _ Caves anD Cave Lire.—There are a few statements made in Dr- <. Packard’s article in the September number of the AMERICAN NATU- o BALIST, which, while they do not affect the argument, seem to Geology and Paleontology. 1105 correction, First, on pp. 814-815, occurs the statement: “It is probable that Cacidotea stygia is seldom, if ever, broughtin contact with Asellus communis, which abounds in the pools and streams throughout the cave region.” For this I cansee no reason. As I have lived for sometime in the cave region, I may say that Cæcidotæa is not confined to “caves and wells fed by underground streams,” but occurs in Bloomington in springs and in the ordinary streams, mingling with its near relative Asellus. Again, except for the single element of darkness, I cannot see how the cave* fauna, occurring in the numerous caves around this town, and extending south to Wyandotte and Mammoth, “is almost completely isolated from that of the upper world.” ‘Too many of the streams in this carboniferous belt drop out of sight, and can be traced directly into caves about here to afford much isolation to aquatic animals. Not having seen the complete article from which his paper “On Certain Factors of Evolution” is an extract, I do not know on what Dr. Packard bases his conclusion (p. 815) that the cave faunz are to be regarded as products of Quaternary times. Of course the peel facies of that fauna is recent, but it is, on the other hand, yond question that the caves themselves have been in process of formation since their rocks were elevated above the carboniferous sea. I know of no argument which forbids the idea of their being peopled in Permian times. The fact that we have no cave fossils giving evidence of a Mesozoic fauna is easily explained by the fact that there was no locality for such fossils to form. Caves are constantly being enlarged by a solution of their walls, and with the wearing away of the rock all cave-animal remains would of necessity be destroyed. find a single morainic boulder.

To explain the existence of the caverns we must predicate streams whose 1106 General Notes. beds have now entirely disappeared, except as they are shown inside the caves. For instance, the Blue river of to-day cannot be con- nected with Wyandotte Cave. The entrance to the cave occurs on a side hill, a hundred feet above the present stream, yet inside the cave there is ample evidence, not only of the long-con- tinued action of small amounts of water, but, in places, the plainest signs of a considerable stream. So, too, in Little Wyandotte, a few rods away. Still, where that water entered the cave, and where it made its exit, are as yet unsolved problems. In the majority of caves which I have seen, the entrance seems a secondary formation produced by a falling in of the roof, or a wearing away of the hill itself. This last is clearly the case with Wyandotte Cave, which apparently once had a greater extent than it now has. In other cases the entrance is through a “sink-hole,” but it requires no little credulity to believe that that little funnel conducted the water which wore away such a cavern as “ Coon’s Cave” in this county (Monroe). believe that the majority of the caves about here had soquines _ essentially their present sizes and dimensions long before the adequate to account for the caves is evident to any one who bier this region.

This supposition has become a certainty, as a result of a more detailed examination of material received from Mr. O. W. Lucas, of Canyon City, Colorado. This consists of a nearly entire skull, with numerous portions of the skeleton, derived from the locality which furnished the typical specimens of Cama- rasaurus supremus Cope, and other Reptilia. It appears that the specimen is specifically identical with one which includes vertebre and a few other bones only, described by me as Amphicotytus lu- casii,’ from the same locality. The species may be therefore called Goniopholis lucasii. e superior surfaces of the skull and dormal scuta are rather finely and profoundly pitted. The orbits are a little smaller than the crotaphite foramina, and each one has a strong supraorbital ne, which is also pitted. The muzzle is of moderate length, and is proportioned much as in the Nile crocodile. Its extremity is neither abruptly expanded nor recurved. The anterior teeth are sculptured with coarse, shallow, parallel grooves. Those of the pos- terior portion of the maxillary bone have opposite angles at the extremities of a transverse axis extending inwards and forwards and outwards and backwards, but the crown is not compressed at the base, though slightly so at the apex. The posterior nares are nar- row, and are divided by a median septum. Their anterior border 18 Opposite the middle of the palatomaxillary foramen.

Comptes Rendus Stenographiques, Paris, p. 146; Vertebrata Tertiary of the United States, 1885, p. 26. ? Bulletin U. S. Geolog. Survey Trans. F. V. Hayden, 1878, p. 391. 1108 General Notes. on “ A comprehensive type of fossil cryptogamic life from the Fort Union group,” illustrating it by lantern views. The fossil in ques- tion was so peculiar that though collected in 1883, he had done little with it until the present season. Photographs of it were sent to various eminent zoologists and botanists, with a view of deter- mining the affinities of the curious specimen. Zoologists could not refer it to any animal, and so considered it a plant; while botanists, knowing no plant like it, thought it possibly an animal. Prof. Ward’s conclusion so far is that it represents a generalized type of vascular cryptogam, with relationships to Ophioglossum, Isoetes, Marsilea, Lycopodium and Selaginella. It is evidently an aquatic, fresh water, as shown by the remains of aquatics in the same con- nection. A central, roundish rhizoma or rhizoid, is surrounded by slender, flexuous bodies, radiating in all directions, each expanding from a rather narrow base to a broad club-like end. The scales are arranged in two or three rows; at the base are found numerous round bodies like spore cases, and the free end has a flattened blade about twice as wide as the main stem and rounded. In the general aspect of the rhizoma it is related to Isoetes. In its branches and _ fructification to Ophioglossum and Marsilea, and in its scales to Lycopodium and Selaginella. Letters from Prof. Farlow, Dr. Nathorst and Count Saporta, were read, and these scientists sug- gested a possible connection with the same forms of cryptogams as Prof. Ward had himself imagined. In a discussion which ensued, Prof. Seaman called attention to the similarity the specimens pre- sented to the structure of the hairs of Drosera rotundifolia. It would indeed be strange if in this fossil plant of Cretaceous times we should have foreshadowed and produced on a large scale the hairs of Drosera, each acting independently instead of working 12 common. It must be said, however, that the chances are greatly 1n favor of the view of Prof. Ward, that it is a generalized form of certain groups of the vascular cryptogams.—Jos. F. James. A Hornep Dinosaurtan REPTILE.—In the December ape ber of the American Journal of Science and Arts, Prof. O. C. Mars describes parts of the skeleton of a Dinosaur from the Laramie for- Mineralogy and Petrography. 1109 of them, including a horn-core and posterior part of the skull (Plate XXXII., fig. 8). These fragments were also found in the Laramie bed of Montana, probably at no great distance from those described by Prof. Marsh. I did not determine the genus to which this cranium should be referred, since there were already known nine genera of Dinosauria from the same horizon to one or the other of which, it was sure to belong. The observations of Prof. Marsh will determine this point. The affinity to Hypsirhophus referred to by Prof. Marsh indicates Polyonax (Cope) as the form to which the species probably belongs, although this is of course a mere sur- mise. That genus was described from vertebre and limb and dermal bones (Cretaceous Vertebrata U. S. Geol. Survey Terri., IlL., p. 63, Plates II. and IIT.). Some of the latter were probably identified with doubt as parts of the shafts of limb bones, but they resemble more nearly some of the spinous dermal bones ascribed to Hypsirhophus by Marsh. It would have been well if the final publications of the Hayden Survey could have been completed by the Director who succeeded im in charge, instead of new publications taken up. In that case the continued duplication of the work of the first survey by its successor could have been avoided.—E. D. Cope. MINERALOGY AND PETROGRAPHY.' PrETROGRAPHICAL News.—Liwinson-Lessing? has suggested a scheme for the classification of elastic rocks. He would divide these into tuffs, breccias, congl tes, pseudoschists and slaty rocks. ' Tuffs he would confine to rocks made up of crystals, or pieces of crystals, and separate minerals, and would subdivide into agglom- erates-tuffs (subaéreal) and tuffogenous sediments (submarine). The agglomeratic tuffs he would further separate according to structure, Tuff-like rocks produced from crystalline rocks by orodynamic forces, or by weathering, he would call tuffoids, and distinguish as elasto-tuffs and decomposition-tuffs (Verwitterungs tuffen). The breccias are composed of pieces of rocks cemented by rock material. They are divided into primary, or voleanic, an dary, or metasomatic breccias. The volcanic breccias include the lava together by a molten rock, and tuff-lavas (Spaltung’s breccia), Edited by Dr. W. S. Bayley, sy aged Waterville, Me. ? Miner. u. Petrog.

The pyroxene, comprising the larger part of the rock, is of a light green color, and possesses the diallagic parting. The plagioclase—labradorite and anorrhite—is present in large quantity in some varieties of the rock, and always shows a tendency to alter into wollastonite. The hornblende and quartz are both secondary. These pyrox- enites resemble very closely the flaser-gabbros of the Germans, but are supposed by Barrois! to be metamorposed limestones. He describes a limestone in contact with granite in the same region, in which the minerals characteristic of the pyroxenites have been developed.—Chrustschoff? includes under the name perthitophyre a series of dyke rocks occurring in the Department Volhynia, Russia, whose characteristics differ from those of any rocks heretofore described. They consist of an interstitial micro- pesthitic substance, in which various amounts of idiomorphic quartz, labradorite, monoclinic and orthorhombic augite, olivine, and other minerals are imbedded. In the coarser varieties the iron-bearing minerals are not abundant, while in the finer grained kinds they are in as large quantity as the feldspar. In the course of his article the author describes parallel growths of diallage and acicular crystals of an orthorhombic pyroxene, and also an appar- ently triclinic pyroxene. He also mentions the existence of anatase as an inclusion in the feldspar and quartz, and gives in brief the properties of a mineral whose nature he is unable to determine.— Sandberger’ describes inclusions of hypersthenite, olivine-gabbro, and a rock composed of olivine, arfvedsonite, picotite, eustatite, sanidine and augite, from the phenolite of Heldburg, in the Thür- inger Wald.—Posepuy * gives brief descriptions of a few sections of adniole in the course of an article discussing the structure of the well-known mining region in the vicinity of Przibram, Bohemia.

MINERAL SYNTHESES.—Dollter? has effected the synthesis of a large number of micas by fusing together aluminium-bearing sili- cates and metallic fluorides. The hornblendes yielded biotite when fused with sodium and magnesium fluorides. The alumina-free hornblendes gave olivine or augite. Garnets yielded meroxane. Micas of different kinds were obtained by fusing K, Al, SiO, with sodium fluoride alone; or with this salt and potassium fluosilicate or magnesium silicate, with or without the addition of ferrous Silicate. All the micas thus produced were decomposed when the temperature of the mass was raised toa white heat, and olivine, augite or scapolite were formed. Muscovite was obtained from andalusite by fusing it with potassium fluosilicate and aluminium fluoride, and zinnwaldite, when a little lithium carbonate was added to the mixture. Many other points of interest are found in the paper, which will undoubtedly prove of value in discussing the paragenesis of minerals in rock masses.—Among the other minerals produced artificially within the past few months, attention may be called to rhodonite and tephronite, which Gorgen? obtained by heat- ing to a high temperature, in the presence of water vapor, a mix- ture of manganese chloride and precipitated silica.

BOTANY.‘ A FEW NOTABLE WEEDS or THE NEBRASKA Pxains.—In examining the constitution of various flore one is struck by the fact that with the other changes there is a notable change 1n the weedy plants as well. Of course a “weed,” from a botanical standpoint, is as reputable a plant as any other. It is in fact but an eminently successful organism in the struggle for place, and on this account it which jog along in a mediocre way, neither advancing nor falling much behind under our observation. Upon the Nebraska plains, . the plants which push themselves into place so prominently as to be called “weeds” by the farmer, are partly artly introduced species, some of which have come in from the southwest within a comparatively recent period, while others have come along with the tide of immigration from the eastern part of the cont- nent, and from the old world. e © The plant which, all things considered, is the worst weed, from the popular point of view, is doubtless the Sand-bur (Cenchrus tribuloides L.), a peculiar grass of variable habit. As mostly seen, 1 Amer. Jour. Sci., Sept., 1888, p. 175. 2 Ib., Sept., 1888, 3 Neues Jahrb. f. Min., ete., 1888, ii., p. 230. t Edited by Prof Chas. E. Bessey, Lincoln, Neb. - Botany. 1115 growing almost horizontally from their bases, but when grown in a ense mass it is a tall, erect grass, reaching the height of eighteen to twenty-four inches, or even more. The heads consist of numerous it is a small plant of a spreading habit, the short flowering stems often spiny flower clusters, which become easily deciduous upon the ripen- ing of the seeds, The spines cause these to adhere tenaciously to the hair of animals or to the garments of the passer-by, and when abundant it is almost impossible to remove them until by hard usage the spines have become worn and broken. The seeds are thus carried long distances before being dropped. The plants thrive upon any soil, from the almost barren sands of the rivers to the rich loam turned up by the railway builders in making their embankments. I am of the opinion that the Sand-bur originally grew upon the sandy islands and banks of the Republican, Platte, Loup, Elkhorn, Niobrara and Missouri rivers, and that from them it has spread since man has broken the tough sod of the plains. It could not compete single-handed with the wi , but as soon as the farmer began his warfare against the latter, the Sand-bur found and improved its opportunity for extending its habitat. The armer has unintentionally and unconsciously given it the opportu- nity of going up and taking possession of the land. ; Buffalo-bur (Solanum rostratum Dunal) is the only appropriate name given to a pest which is rapidly increasing all over the plains. The prickly plant and fruits are almost as troublesome as the Sand- bur. I have seen fields in south central Nebraska almost com- pletely filled with Buffalo-burs. What its original habitat was I do not know, but certain it is that now the plant is accommodating itself to the new conditions brought about by the cultivation of e soil. The sunflower of the plains is the original of the ordinary sun- ' flower of the gardens (Helianthus annuus L.). It is found every- where, and varies in height from a few inches to fifteen feet or more. Upon the unbroken prairies in the White River country of northwest Nebraska I have seen it growing with the prairie grasses, where it consisted of a single erect stem, not more than ten or twelve inches in height, and bearing a single small flower head. Sarir, where the soil had been somewhat broken, m by the wash- ing of water, the pawing of buffaloes, the of a wagon, or any other cause, the dasa were taller, aN with a few branches. Upon the mounds made by the prairie dogs, pocket gophers, and ground squirrels, the plants were still larger, approaching the vigor of vegetation shown by them in the eastern parts of the State. In the settled portions of the State the sunflower grows to a great size, and produces a multitude of branches and flower heads. I have often seen plants whose diameter (measured from the tips of the branches on each side) was fully six feet, and whose height reached 1116 General Notes. twelve to fifteen feet. It is a curious fact that all over the plains there is a tradition that the sunflower was introduced by the Mor- mons, who scattered its seeds by their trails, in order to enable the faithful who came later to follow their tracks. It is scarcely neces- sary to say that this is an error. The sunflower doubtless sprang up in abundance along the Mormon trail, and marked it, but so it did along every trail where the sod had been broken enough to give the plants a better opportunity for growth. : Squirrel-tail grass, as it is called in the books, and in classes in botany, or “Tickle grass,” as known to the farmers (Hordeum jubatum L. of the botanists), is one of the most abundant of the weedy grasses of the plains. It appears to have originally grown along the sandy margins of rivers, and upon the bare ground about ponds and salt springs, from whence it has spread rapidly to road sides and fields since the advent of white men. It is not naturally one of the prairie grasses proper. In fact, as it is an annual, it cannot compete successfully with the strong-rooted perennial grasses until the latter have been partially displaced by the breaking of the sod; but when once it obtains a foothold it spreads with great rapidity. he jointed rhachis of the head breaks readily into short pieces, each of which bears a few flowers with their widely spread- ing barbed arrows. Each fragment has a most persistent creeping power, which enables it to work its way through heavy clothing, and the densest of hair or wool. In this way the grains are carri by man and animals for long distances, and when finally the arrows are broken up, and the barbs come out, the seeds are dropped upon . the ground, ready to start up in early spring. Tumble-weeds abound everywhere now, but I am confident that they are likewise dependent for their present abundance upon man's agency in breaking the original sod. The most common tumble- weed is Amarantus albus L., well known throughout the prairies and plains. Wherever a settler has broken up a tract of land these plants appear in great numbers; in fact it is principally upon such breakings that they are to be found. In the autumn I have seen great tracts of from fifty to a hundred acres or more entirely covered with the hemispherical or almost spherical examples of these ee ble-weeds. With the advent of the frosts and heavy winds 0 October and November, the stems are broken off at the ground, or in some cases the root.is pulled up or twisted off, setting free n round body, which then goes tumbling and bounding over the plains, scattering its seeds as it goes. Whether these tumb e- weet occur as depauperate plants upon the plains, intermingled with the grasses, I do not know, but it is certain that none occur there large enough to roll and tumble. The plant is not a tumble weed u se the opportunity of growing freely upon broken and sou. Botany. 1117 _ A second tumble-weed is Cycloloma platyphyllum Moq. It grows in almost exactly the same way as the preceding. I first observed it along the Platte River, where it covered acre after acre of the sandy river border. It occurs also on the upper Elkhorn River and the lower and middle portion of the Niobrara. owever, upon the upper Niobrara and in the White River country the only tumble-weed is Amarantus albus. Probably this second plant (Cycloloma) has for a long time been a tumble-weed upon the plains, especially on those portions adjacent to the streams mentioned. Both species will increase in numbers for a few years, during the time when settlers are breaking up large tracts of the prairie sod, and then, as better and more continuous culture is practiced, they will gradually decrease in number and importance.—Charles E. Bessey. Asn Rust IN 1888.—The Ash-rust, Zcidium frazini, has been very abundant on Frawinus viridis in Lincoln, Neb., this year. It was especially common in the latter part of June and first week of July. At that time I observed a number of trees of which almost every leaf (as also in many cases were the petioles) was affected to such a degree that many of them were curled and distorted. This some interest from the fact that, although abundant in 1885, this rust was rare in 1886 and 1887.—N. R. Pound. orty pages are devoted to a systematic study of the species repre- sented in the sections. Under each species there is first a specific description of the tree given in quite popular language; then fol- low geographical distribution, physical properties, uses, medic properties, ete.

The work will be a most valuable one, and it is to be hoped that it will be continued to com- pletion. Every botanical department ought to afford this set, as the price ($5 per volume) is very reasonable. The volumes are put up in book form, so that they may be placed upon ordinary library shelves.—Charles E. Bessey. ZOOLOGY. THE CONTRACTILE VACUOLE.—The dispute regarding the na- ture of the contractile vacuole in the protozoa is not atan end. Dr. De Bruyne records (Bulletin Roy. Acad. Sci. Belg. LVT., 1888), his belief that it does not communicate with the exterior, and that it is not ssed of excretury functions. Prolonged study tends to show that the contained fluid is not expelled from the protozoan, but that it is forced to other parts, to again return to form the vacuole. He would rather regard it as of respiratory and circulatory functions and thinks that the contained fluid may possibly have nutrient pro- perties. © An ENDOPARASITE or AMPHIURA.—Dr. Fewkes records (Proce. Boston Soc’y. Nat. Hist., XXIV ., p. 31, 1888) the existence of a Cope- pod Crustacean parasitic in the brood cavity of the common Brit- tle Star, Amphiura squamata, at Newport,R. I. In the specimens af- fected the ovary had degenerated into an amorphous mass and that the cavity contained either the adult Copepod or eggs containing the young in all stages of development. Fewkes also records the exist- ence of this parasite in another place (Bulletin, M. ©. Z, XIIL., 1887) but does not give it a description or a name. Comparison should be made with Cancerilla tubulata which is described by A. Giard (Comptes Rendus, 1887, p. 1189) as parasitic wpon the same brittle star at Fécamp. There the young attach themselves to the ends of the anus and approach the disc as they grow older. | THE CLASSIFICATION OF THE MyrtapopA.—So far as I am aware, no naturalist has questioned the naturalness and homage- neity of the group of Myriapoda. To me it seems that this unity is oe rather than real ; that the Chilopods and Chilognaths are gg together on account of superficial resemblances, rather than __ from community of descent, upon which all true classification must ; ~ be:based, and that those features which they have in common are at : _ the same time possessed by all the other air-breathing arthropods: Zoology. 1119; Every zoologist who has essayed the problem of homology present- . ed by the head and the appendages, has made a more or less con- spicuous failure, and this, as I am inclined to believe, has resulted solely from the fact that there is no true homology in these parts. I will not now discuss these points in detail, but will indicate the facts and reasons for my views. perfect definition should include all the objects. intended to be defined, and at the same time exclude all others. Applying this we find it all but impossible in few or many words to frame a defi- nition which will at once characterize all myriapods, and exclude the hexapods, and at the same time take into account structures which have any morphological value, The best we can do is some- what after this fashion :—Myriapods are air-breathing Arthropods, with elongate bodiesand more than three pairs of walking legs. Farther than this we cannot go,and even this definition will admit Scolopendrella which many now regard as a Thysanure. Omitting for the present all mention of these features which yriapods have in common, we will take up the points of difference between Chilopods and Chilognaths.! The Chilognatha (Millepods, galley worms) have a head which bears, besides anten- næ, only two pairs of appendages—a pair of jaws or mandibles, and. an under-lip composed of the coalesced first maxille. To the head succeeds the more or less elongate equally segmented body of which - a few anterior segments bear but a single pair of legs, while all the rest bear two pairs of appendages, thus apparently affording an ex- ception to Savigny’s law that each segment of an Arthropod can . bear but a single pair of appendages. The bases of these legs are ° placed close to each other, the sternal surface being reduced to an extremely narrow plate, or being entirely wanting. In the Chilopods, on the other hand, the head bears three pairs of mouth-parts, a pair of mandibles and two pairs of maxille while. each segment of the body bears but a single pair of walking legs, and these are widely separated at their base by the broad sternal element. Numerous attempts, as was said above, have been made to introduce homology between these two groups in these respects, Heathcotes researches show , that that the diplopodous segments ? Phila Trans. Vol. clxxix., B. (1888). of Iulus are in reality double, but they also show that in the head there are no traces of more than two pairs of post-oral appendages. In the Chilopods the Stigmata which communicate with the trachea, are placed at the sides of the body in the thin membrane join- ag the dorsal and ventral plates, thus being clearly above and out- side the line of the legs; in Scutiger they aredorsal. In the Chilog- ‘1 Pauropus and the Pauropida are omitted because we know almost nothing of their internal structure and their development. | ; - 1120 General Notes. gnaths the stigmata are placed beneath or even in the coxal joints of the legs. In the genital organs the most marked differences occur. In the Chilognaths both ovary and testis consist of a simple sac-like organ, communicating by a double oviduct or vas deferens with the paired genital openings situated one on either side, at or behind the bases of the second pair of legs. In the Chilopods, on the other hand, the sexual organs possess but a single efferent duet, and this opens in the middle line of the posterior end of the body just below and in front of the anus. In the Chilognaths both ovary and testis are below the intestine, a position indicating inferiority. In the Chilopods they have their origin in the same position which they permanently occupy in the other group, but with development they come to occupy a place above the alimentary tract. e spermatozoa, in the Chilognaths, are quiescent; in the Chiolopods they are active. The position and character of the genital ducts in the Chilognaths is such as to lead to the supposition that here, as in many other metameric forms, they may have had their origin in a pair of segmental organs which have become specialised for carrying away the generative products. Heathcote’s account of the develop- ment of the generative glands of Iulus certainly does not oppose this view. Inthe Chilopods, on the contrary, there is nothing in the adult structure (we know nothing of the development) which would even suggest such an origin for the generative ducts. _ Now these points are all of considerable morphological import- ance, as we must, for instance, go far back in the ancestry to find a condition from which we can derive the two types of generative organs mentioned above, and exactly what structure that ancestor must have had it is difficult to say. It is, however, clearly impossi- ble to derive either condition occurring in the Myriapods from the er. : _. + If, however, we turn to existing forms to find the nearest relations of either group, our search is to a certain extent easy, for the next of kin of the Chilopods are certainly found in the Hexapoda. | all those points where Chilopods and Chilognaths disagree, the Chilopods and Hexapods are in harmony. Both have the same number of mouth-parts; both have the appendages segmentally } _ arranged ; the spiracles the same, while there is no little similarity _ between genital organs, ducts,and openings. Indeed taking Scolopen- _ drella into consideration, it seems impossible to frame a definition which will serve to separate all the Hexapods from the vere 2" It would seem then that we should unite both Chilopods and Hex- apods in one class. _ With regard to the Chilognaths, it seems not so easy to trace — : relationships.

Gage states (The Microscope, VIII.) that the blood corpuscles of the lamprey are unlike those of the non mammalian vertebrates and like the mam- FIBRES oF SHort Muscies. — In order to ascertain whether the statement made by Kölliker that in the short muscles of the fish, frog and bat, the fibres are of the same length as the muscle, and have rounded ends, is applicable to the more minute vertebrates, . S. P. Gage has studied the muscles of the mouse, shrew, bat and English sparrow. She concludes (Zhe Microscope, VIII.) that the muscular fibres may extend from end to end or may terminate at one or both ends within the muscle, tapering to a point. She cludes that the difference between the skeletal and cardiac mus- cles is not so great as has been supposed. | NOTES on THE AMERICAN TRIONYCHIDa.— According to Agassiz there are six species of American Trionychide, belonging to three different genera. I am indebted to Prof. G. Brown Goode and Mr. F. A. Lucas, of the Smithsonian Institution ; to Prof. A. Agassiz and Dr. S. Garman, of the Museum of Comparative Zoology in Cambridge ;* to Prof. A. Gunther and Mr. G. A. Boulenger, of the British Museum, to Prof. O. C. Marsh, of the Peabody Museum, to Mr. T. Gillespie, of Hard Times Landing, La.; for the opportunity they have given me to examine a great number of American Trionychide. oo s a preliminary report I may note the following conclusions :— 1. The type of Testudo ferox Schneider, descri y Garden= Pennant in the Philosophical Transactions of London for 1771, is not Piatypeltis of Agassiz; but a species of Axpidonectes. : . ltis ferox of Agassiz is not Zestudo ferox Schneider, bnt a new species, which may be called Platypeltis Agassizit. 3. Callinia microcephala Gray, of the British Museum, with the locality Sarawak, is Amyda mutica Les. 1 To Prof. Angelo Heilprin of the Philadelphia Academy. 1122 General Notes. According to my researches there are the following American Tronychide. Platypeltis Agass. 1. Playpeltis agassizii mihi. = Platypeitis ferox Agass. non Schneider. Aspidonectes Wagler. 2. A. ferox Schneider. . A. asper Ag. 4, A. spinifer, Les.=A. nuchalis Ag. 5. A. emoryi Ag. 6. A. muticus Les. At the same time I should like to call attention to the enormous sexual difference in Aspidonectes muticus Les. It is well-known that the males have very much longer tails than the females on all the Trionychide. The male of A. muticus has the plastron more develo than the female: the Hyo-, and Hypoplastra meet with the callosities nearly in the median line. The callosities extend very much more in the male than in the female; in an adult male the callosities cover the plastral-bones entirely A very peculiar circumstance is, that the adult male is only about half as large as the adult female and that the males are in consid- erably smaller number than the females. Among thirty-six specimens of A. muticus from the Ohio River, there were only seven males. The fishermen consider the males and females as dif- ferent kinds of animals, so great is the difference. Ido not know yet, whether the other Trionychide show the same considerable sexual difference. It is very interesting, however, that Podocnemis shows it. — Toao Martins da Silva Coutinho,! makes the following remarks about the male of Podocnemis expansa. “The male, named Capitary, is distinguished from the female, by its size; it is only about 0, 7 m long (the female 1, 2m and more) and the tail which is twice as long, reaches a length of 1. 2 m.— The circumstance that only a smal! number ot Capitary are found among hundreds of females, proves, in some way, that a single male _ is sufficient for the fecundation of a greater number of females.” — iw) -= Q. Baur, New Haven, Conn. _ _ McGee on Mrapow Larks anp RILEY on ENGLISH SPAR- ~ ROWS.—Ata meetingof the American Ornithologists’ pers held ” the hall of the National Museum in Washington, Prof. McGee, the Geological Survey, read a paper detailing his observations upon the two forms of North American meadow larks, as found in Iowa. ma tion, Avril, 1 e : Amazone, Bulletin de la Société Impe | ? Loology. _ 1128 The two species or geographical varieties, whichever they may be, are distinguished by certain peculiaritiés in their song. e eastern species, Sturnella magna, extends about two-thirds way across the State of Iowa, while the western form, S. neglecta, is found nearly as far east as the Mississippi River. At their extremes of distribu- tion both of the forms are easily recognized, and are typical exam- ples. But in the intervening region, where the two overlaps, as it were, the birds were not to be positively separated by note alone, a sight of the bird itself being generally necessary for positive identi- fication. Whether the variation in song was due to imitation of one by the other or to an actual intermingling of the two, he did not attempt to decide. In referring to the reason for the distribution of the two species, the agency of the glacial period was evoked. At the time when the ice reached its greatest extension southward, the waters of the Gulf of Mexico extended northward, forming a junc- tion with the ice and dividing the continent into an eastern and a western portion. The suggestion’ was made that if at a period anterior to the glacial epoch one species was widely distributed over the continent, the time that elapsed until the normal condition of the country was again reached was sufficiently long to allow dif- ferentiation to proceed, and two species or distinct varieties to be ormed. l In the discussion which ensued Dr. Cones took the ground that a very long period of times was not absolutely necessary for formation of new races, varieties or species: that environment or food often causes changes with considerable rapidity, and that it is probable new species, so-called, are being formed under changing conditions in our own day and in short periods of time. Dr. Mer- riam mentioned that changes in coloration are often due to change of food : that a breeder in Holland was so well known for his skill in “coloring up” Flamingoes, that these birds were sent to him from all parts of Europe. By some change in food, a secret known only to himself, he was enabled in a short time to restore them to full color. Yet in a short time the new color was lost and the original faded aspect resumed. Prof. C. V. Riley cited numerous instances of the distribution of insects similar to that of the meaaow larks. Dr. Gill called attention to similar cases with fishes. a may be well to note here similar parallel cases in the plant world. atis viorna is a well-known, widely distributed plant of east- ern North America, extending, however, only as far west as Kansas, where it is not common. C. pitcheri, classed by some as a variety of Viorna, is a western form found nowhere east of the lower Wabash valley in Indiana, but extending westward through Mis- souri, Arkansas and Texas. It is extremely probable that the two forms owe their distribution to the same cause or causes as the two forms of meadow lark above referred to. Some species of Verno- 1124 General Notes. nia (Ironweed) seem in similar positions. Four of the species are exclusively trans-Mississippi. One oversteps the boundary into west Tennessee. Two others, on the contrary, are eastern and cen- tral species which overlap the others by extending into Iowa and Kansas. It is further interesting to find certain hybrids between the eastern and the western forms, which, if they came from the debatable ground of Iowa, Missouri and Kansas, would furnish additional interest to the problem. Another paper read at the same meeting was by Prof. Riley, upon the English sparrow. Examination of the stomachs of more than five hundred specimens showed that only from fifteen to seventeen per cent of the whole number contained any insect remains atall. The rest contained grains or seeds of various sorts, straw and gravel. The insects found belonged to all orders, and were generally such as are either harmless to the agriculturalist or even actually beneficial. The stomach of a single specimen of a truly insectivorous bird contained wo hundred and fifty web worms. Such a bird would do more good in ridding trees of various insects than all of the eighty-two sparrows in whose stomachs insect re- mains were found. Investigations of a similar nature carried on by Mr. Charles Dury, of Cincinnati, lead to a similar conclusion, that the value of the English sparrow as an insect destroyer 1s nothing compared to that of a truly insectivorous bird, and that it is injurious rather than beneficial—Jos. P. James. Brocas CONVOLUTION IN THE ApES.—Dr. Hervé in the Bul- letin de la Société d’ Anthrpologie de France (April, 1888), discusses the disputed question as to the development of the third (Bro- - eas) frontal convolution in the monkeys. After an examination 0 the homologies of the fissures presented by that region of the brain, he finds that it is wanting or extremely rudimental in the Quadru- — mana, while it is present in the Anthropomorpha, though smaller in the apes (Simiide) than in man. This is interesting, as it con- firms the evidence from the osteology, that the apes and man form a natural group, distinct from the monkeys and lemurs. It also points to the possibility of teaching some of the apes to speak, and also to the probable gradual acquisition of this important charac- teristic of man.—E. D. Cope. ZooLogicaL News: Prorozoa.—-In the Zoologischer Anzeiger (No. 286), G.

There is no definite locality assigned to any of the species, r. C, D. Sherborn has recently published in London a volume of 152 pages, devoted exclusively to a bibliography of the Forami- nifera, recent and fossil. Sponees.— Wierzijski ( Verhandl. k. k. zool-bot. Gesellsch., 1888) thinks that all the so-called species of Euspongilla ‘are but one in reality, the differences being the result of environment. He also found near Lunberg a sponge which he regarded as closely allied to Potts Spongilla terrenove, but afterward concluded that both his form and the Newfoundland species were deformed indi- viduals of Myenia miilleri. Ca:LENTERATEs.— Vogt thinks that Arachnactis is not, as the younger Agassiz thought, the young of the Edwardsia but a dis- tinct genus allied to Cerianthus and like the latter retaining its distinctly bilateral character throughout life. Though he does not expressly say so, Vogt is apparently ready to adopt the view that in the Hydrozoa as in the Anthozoa the free-swimming form is the primary and the attached condition secondary and adaptive. Worms.—O. Zacharias records (Biol. Centralblatt, VIII., p. 542) the occurrence of a land planarian (Geodesmus terrestris) between the A met cob the mushroom (Agaricus deliciosus). oy ago we referred to the account given by Dr. Walker of f Bufalo, concerning the life history of the tape worm of 1126 General Notes. fowls. He claimed that the intermediate host of the worm Syn- mus was to be found in the earthworm. Recently (Nature, XXXVIII., p. 324) Lord Walsingham gives facts collected from the experience of sportsmen which tend to corroborate this view. In dry summers when but few earthworms come to the surface, game fowl are comparatively free from the disease, but when worms are abundant, the fowl are more difficult to rear. G. Brandes, in a preliminary communication embodying his ana- tomical discoveries, points out that the Trematode Holostomum has been regarded wrong side up, the “ventral” surface of authors being really dorsal and that the “larval anus” of the Tetracotyle stage of the worm is but the beginning of a gland and its duct, the alimen- tary canal ending blindly in the body parenchyma. Dr. J. . Fewkes describes and figures (The Microscope, 1888) a new type of marine larva found in the Bay of Fundy, and in Massachusetts Bay, which is regarded as having brachiopod, chetopod, and bryozoan features, but which seems to be nearest Mitraria in its affinities. The adult to which it belongs is unknown. ewkes, in conclusion, has some remarks upon the characters of the common ancestor of Polyzoa, Brachiopoda, and Cheetopoda, which lead him to suggest as a name for this hypothetical form “ that of Mitraria, which up to the present is applied simply to the larval form of a single genus of Chetopoda.” Iijima and Nusata record some new cases of the occurrence of i i ae liguloides in Vol. IT. of the Journal of Science of the University of Tokio. MoLLUsCA.—Some sixty years ago Desmarest and Lesueur pro- posed to issue a series of illustrations of Polyzoa and Hydrozoa, and fourteen plates were engraved on copper by the latter. A few of the plates were distributed, but no accompanying text was ever prepared. Recently E. Pergens (Proces- Verbal de la Soc. Roy. Malacol, Belg., Sept., 1887) has examined the original manuscripts and the types preserved in Havre, and has given identifications of the Polyzoa there figured. Protozoa.—The Martini-Chemnitz ‘Conchylien-Cabinet” still appears at intervals. Numbers 356 to 361 have recently appeared, containing plates of Cardita, Pecten, Spondylus, Cerithiide, Chama, Cardita, Solen, and Modiola. Paul Pelseueer denies (Bull. Scientif. France et Belgique) the existence of a group of Orthoneurous Gastropoda. a _, Crusracea.—According to the Journal of the Royal Ipero E ~ deal Society, D. Bergendal has described the occurrence of distinctly ee male copulatory appendages on female crabs. In many cases there Zoology. 1127 were no appendages on the first segment of the abdomen; in others spoon shaped; in a few like those of the male. Only the useless and normally rudimentary first pair of appendages show this modi- fication, the second pair which are functional are never modified in this way. Tuniara.—Prof. Herdman, in the Proceedings of the Bivlogi- cal Society of Liverpool (1887, p. 24), thinks that recent investiga- tions tend to establish that the pineal gland and the pituitary body of the Vertebrata, are both of them the remains of organs which reached the surface of the head in the ancestral Chordata, the pineal in the form of a median dorsal organ of sight; the pituitary possibly also as a sense organ placed on the front of ‘the head close to the mouth opening. Brrpos.—Dr. R. W. Shufeldt contributes to the Auk (Vol. V Oct., 1888) figures of the skulls of Habia melan Si gt and Pipilo megalonyc, from which he shows that the grosbea possessed -of skeletal characters not shared by any other fringilline birds, and are possibly entitled to family rank. Mr. N. 8. Goss, of Topeka, Kansas, wishes information concern- ing the western range of Anas obscura, the black duck. He is inclined to doubt its occurrence west of the Mississippi, all the specimens which he has examined proving to be the Florida duck. Mammats.— At the meeting of the Linnean Society of New South Wales, Aug. 29th, 1888, Professor Tate exhibited a salted sc sun-dried mammal from Alice Springs, Central Australia. In appearance the Gea resembled a Cape Mole (Chrysochlo- a Its teeth and limbs indicated an insect diet and a burrowing life.

ENTOMO- LOGY.’ —The establishment by the United States Government of an agricultural experiment station in connection.with each of the state -Agricultural Colleges has resulted in a great increase of attention ~to experiments in economic entomology. This increased attention : has brought clearly to light the inadequacy of the methods com- ‘monly employed in experiments in this field. In fact the state of -entomological science is such that he who wishes to conduct careful - experiments, except in a few simple lines, is first forced to develop the methods of investigation. Although there are many entomologists engaged in research, and „although the literature of the subject is a vast one, more than a ‘score of journals being exclusively devoted to this specialty, com- paratively little is done in the study of the transformations and : habits of insects, or in making practical applications of entomology. With the exception of a few government entomologists, the ener- -gies of the workers in this field are almost entirely devoted to the description of species. And although a few workers have achieved : very important results in the study of the habits of insects, and in - making practical applications of the facts observed, they have done this with very crude apparatus, and often by methods which cannot -be relied upon to give exact results. While magnificently equip laboratories of physiology and histology are springing up at all of ‘the scientific centres, the student of the habits of insects contents himself with a few breeding cages scarcely better than those used — < by Réaumur a century and a half ago. aan. - ‘An illustration of the imperfection of the methods commonly -employed is the fact that experiments with insecticides are usually __, conducted only in the field, where the conditions cannot be con- ‘trolled.

Would it not have appeared that four-fifths of the insects had been destroyed ? hile it is evident that ultimately we must depend upon field experiments for demonstrating the value of methods of preventing the ravages of insects, the danger of error in such experiments is so great that it is unwise to depend upon them in working out princi- ples upon which such methods are based. Obviously the worker in applied entomology needs a laboratory and apparatus as much as does the chemist or physiologist ; and this laboratory should be different from our ordinary entomological laboratories. The greater number of subjects which a worker in this field should investigate fall under two heads: first, studies in the life- histories of insects: second, experiments in the destruction of noxious insects or of preventing their ravages. ork in neither of these lines can be well done in an ordinary entomological labora- tory. In order to make accurate investigations of this kind it is necessary that there should be a place where living plants can be ept with insects upon them, and that all of the conditions of growth of both plants and insects should be under control. We have already given an account (Ante, p. 468) of the Labora- tory of Experimental Entomology at Cornell University. A view S the exterior of this building is now furnished our readers. Plate XIX. Soon after the erection of this laboratory we found that it was desirable to designate it by a name which should distinguish it from the entomological laboratory of the University where instruction is given. As this, so far as we know, is the first building of its kind, we were forced to coin a word ; and have proposed the name Jnsec- tary for buildings arranged for keeping or raising living insects. We hope that the time is near when the need of an Insectary for entomological work will be as fully appreciated as is the necessity for a propagating house for the horticulturist or a conservatory for the botanist. 3 But the building is not all the bo ots required for the ento- - mological work of the future. e need specially constructed apparatus for this work. The breeding-cages and the methods of observation and preservation of specimens which we have inherited from the last century will not meet all the requirements of the com- plicated problems we have to solve. There must be more accurate methods of observing the habits and transformation of insects, more ect ways of testing insecticides, and better means of preserving | specimens for study. It is not too much to hope that the m of entomology of the year 1900 will be as much in advance of those of to-day, as the present methods of histology are in advance of those of fifteen years ago. With the hope of stimulating the study of methods, I present 1130 General Notes. below descriptions of a few simple devices which I have found of much use in my entomological work. The most important of these is a device for observing subterra- nean insects. This device I have termed a root-cage. It consists of a frame holding two plates of glass in a vertical position, and only a short distance apart. The space between the plates of glass is filled with soil in which seeds are planted or small plants set. The width of the space between the plates of glass depends on the width of two strips of wood placed between them, one at each end, and can be varied according to the necessity of each experiment. Outside of each glass there is also at each end a strip of wood for holding the glass in place. The strips are fastened by means of wedges forced between them and buttons projecting beyond the edges of the end pieces, as shown in the figure. It is necessary to haye wedges upon only one face of the cage. By making the three strips of wood at each end of the cage (one between the glasses and one outside of each), of different widths and interchangeable, the width of the space between the glasses can be easily varied. imme diately outside of each glass there is a piece of blackened zinc which slips into grooves in the strips at the ends, and which can be easly — removed. When these zincs are in place they keep the soil dark. In the first lot of root-cages that I had made holes were bored in the bottom to provide for drainage. But the danger of the escape of insects through these holes has led me to depend on the pec of the water through the cracks between the glass and the wooe A layer of very coarse sand one inch in depth at the bottom of the space between the glass facilitates drainage. Entomology. 1131 If the space between the two plates of glass be very narrow, when the seeds which have been sown in this cage germinate, a large part of the roots will ramify in the soil so near the surface of the glass that they may be easily seen by simply removing the piece of zine already described. When the plants have become well estab- lished they may be infected with the insect pest to be studied, and continuous observations can be made without disturbing them. Thus at the present time I have corn growing in these cages with Wire-worms feeding upon its roots. In other cages I have clover growing, the roots of which form an almost continuous mat on the inner surface of the cage. Better results can be obtained in this way than by going into the fields and digging up plants; for in most cases the moment plants are dug up the insects stop their work, while in these root-cages continuous observation of the same insect is possible. _ I haye had constructed several large root-cages, the frames of which are of iron, and each side of which consists of eight lights of glass, each ten inches by twelve inches in size. A pit has been dug for the reception of each cage; these pits are walled with brick. When the cage is placed in the pit, the top of it is even with the surface of the ground ; by excluding the light from this pit it is hoped that the roots can be kept under nearly normal condition. These cages have been constructed for larger plants; thus we a ae to plant apple-trees in some, for the study of the root orm of the Woolly Aphis of the apple; grape-vines in others in order to observe the Grape Phylloxera; and hop-vines in still others for use in proposed experiments upon the Hop Plant-louse. These cages are lifted from the ground when it is desired to study them by means of a small portable derrick. Another form of breeding-cage which I have found very useful is made by combining an open-top bell-jar and a flower-pot. The food plant of the insect is either growing in the pot or is stuck into wet sand in the pot and kept fresh as a gardener would keep a cut- ing. large saucer is used, and an inch or more of sand is placed in it. The bell-jar is placed over the plant in the pot and pressed down into the sand in the saucer. The open top of the bell-jar is covered with swiss muslin. The plant or cutting can be kept well watered by pouring water into the saucer without removing the bell-jar. The layer of sand in the saucer saves from drowning those insects that crawl down from the plants. The circulation of air through the muslin at the top prevents the formation of I have long used jelly-tumblers and fruit-jars for —— small ir and for storing pups. I have been much annoyed by ina- bility to preserve the proper degree of moisture in these receptacles If they are supplied with moistened sand and closed tightly the 1132 General Notes. specimens soon mould; if covered by muslin the sand in a short time becomes too dry and the specimens, if they emerge at all, are apt to do so in a crippled condition. I have obviated these diffi- culties by boring a hole in the bottom of the jelly-glass or fruit-jar and setting it in a flower-pot saucer. By pouring a little water into the saucer from time to time, the sand in the jar can be kept moistened and the excessive wetting caused by pouring water upon the sand avoided. The holes in the glass are bored by means of the end of a broken rat-tail file wet with turpentine. Other forms of new apparatus are in use, but they are not suffi- ciently perfected to warrant description at this time.— John Henry tock. EMBRYOLOGY.' EVELOPMENT OF THE PERIPHERAL NERVOUS SYSTEM OF VERTEBRATES.—Dr. Beard? continues his important studies on this subject, which is just now interesting some of the most distin- guished of living students of the general ontogeny of the verte- brates. His results as to the origin of the ganglia of the posterior sensory roots of the spinal nerves, and of the sympathetic system, are startling and unexpected. His discoveries may also be rank as fundamental, and amongst the greatest of recent times, as regard their consequences. The following résumé of his conclusions 1s given in his own words :— | “The spinal ganglia of vertebrates are formed as differentiations of the inner layers of the epiblast just outside the limits of the neural plate. As the result of the cutting out from the epiblast of these ganglionic elements an appearance is presented by the epiblast which is left, to which. Professor His gave the name of ‘ Zwis- chenstrang.’ This has no share in the formation of the ganglia. The ‘ Zwischenrisme’ of His has no existence, but certain portions of the cranial ganglia, called here neural ganglia, aré develo from the epiblast before closure of the neural tube, in exactly th same way as the spinal ganglia. These portions of cranial ganglia are more or less homologous with spinal ganglia, possibly only with the sympathetic portion of the spinal ganglia ‘ Anlagen) After separation from the epiblast, the ve i cranial ganglia and the Embryology. 1133 spinal ganglia get carried up with the closing in of the neural tube, nd come to lie between its lips, but are quite distinct from the central nervous system, and the line of boundary between the two can always be distinguished. After the closure of the epiblastic folds the ‘ Anlagen ° grow out of their position between the lips of the neural tube, and acquire their first and only connection with it by the probable growth of fibres from the ganglia into the central nervous system. The neural cranial ganglia also grow towards the lateral epiblast at the level of the notochord, and fuse with it. Here are the Anlagen of the lateral or branchial sense organs of Froriep and myself. From this fusion in all vertebrates form- elements pass into the cranial ganglia; these form-elements I dis- tinguish as lateral ganglia. The parapodial ganglia of Annelids appear to be homologous with the spinal ganglia of vertebrates, as Kleinenberg suggested, and also more or less with the neural.cranial ganglia. “The anterior roots of cranial and spinal nerves arise as out- growths of ganglia situate in the central nervous system. To form em, cells leave the nervous system and are distributed in the nerve. All the anterior roots at first contain many nuclei, which are of nervous and not parablastic origin. These statements on the anterior roots are only a confirmation of Balfour’s researches. “In addition to the four elements of the anterior and renee roots, two ganglionated and sensory, two motor and unganglionated, distinguished by Gaskell, Hill, and partially by His, the cranial nerves contain a fifth element, derived from the lateral or branchial sense organs. Such are, in very brief form, the main results of the researches recorded in the preceding paper.” Dr. Beard shows that the so-called “ neural ridge” of Balfour is developed from a portion of the epiblast hitherto overlooked by | embryologists, and extending along either side of the medullary plate, and that it precedes by a very considerable interval of time appearance of the “neural ridge” to which it gives rise and from which the spinal and sympathetic or neural ganglia are subse- quently developed. Further observations have been communicated by Dr. Beard to the Anatomischer Anzeiger, III., No. 29, 1888, pp. 875-884 (to be continued in No. 30) on this same subject. His completed results will be published in three parts: Part I., discussing the development of the peripheral nerves in Elasmobranchs and Birds; Part II., Frog, Triton and Lacerta; Part III., Mammalia. Of these, only Part I. has yet appeared in the journal cited below in full. . : It is stated in the conclusion of the first part of the article in the Anatomischer Anzeiger (p. 884), “ It can be proved embryologically _ that of the following cranial ganglia each and every one is made up of two parts, a neural part and a lateral part, which are devel- 1134 General Notes. oped respectively from the sources mentioned above, Olfactory ganglion, mesocephalic, trigeminus, facial, auditory, glossopharyn- gens, and vagus complex.” In a foot-note it is stated, “I hope soon to show that the end-organs of taste arise from such thicken- ings [of the sensory epithelium] which have wandered through certain gill-clefts into the buccal cavity ” (Anat. Anz., p. 879). A NEW ATLAS oF EmpryroLocy.—Nothing to compare with the splendid atlases of Coste on Comparative Embryology, and of His on the human embryo, has yet been published on the Chick. This desideratum will be met by the Atlas d’ Embryologie, by Mathias Duval, just anuounced by G. Masson, Paris. The author has done wisely in keeping it in quarto form, and with forty plates, embrac- ing 652 figures, it will cover the history of bird development very fairly.. The first plate gives views of the egg in the ovary and | oviduct, and the chick in the egg nearly ready to hatch, in short, a “vue d’ensemble de sujèt.” The next two plates are devot to the structure of the egg, segmentation and formation of the blastoderm. Plates IV. to X. show surface views of the blasto- derm and embryo at successive stages. Plates XI. to XL. are devoted to representing sections of the successive stages shown entire on Plates IV. to X. Facts only are presented, theoretical considerations being left to the student after he has mastered the data. The whole is provided with a copious index, and also con- tains an account of the necessary embryological technique involved in a study of the developmeut of the chick. The reviewer pre- dicts that Professor Duval’s work will be welcomed by teachers as a very useful help in the practical study of the subject in the laboratory. The book will be useful for reference to supplement _ other manuals, and, as it seems to the writer, a thorough knowl- edge of the embryology of the chick will best serve as an intro- duction to the wider field of comparative embryology. The appear- ance of this atlas is timely, for it is probable that eventually embryology will have to be taught in order to enable the begin- ner in morphology to understand the significance and relative importance of the data of advanced morphology in general. In taking a survey of the field of embryology, as covered by the existing literature, one is struck by the fact that, in spite of the great activity of the individual workers, but few really exhaustive monographs provided with adequate atlases are in existence. Such beautiful embryological monographs as Goette’s on Bombinator, of Reichenbach on the Cray-fish, are lasting contributions to science ; the works of Selenka and Whitman, too, and, amongst the produc- as tions of the older workers, the great monographs of Von Baet, Rathke and Bischoff, must ever command admiration. Complete Embryology. 1135 as some of these are, we are still deplorably deficient in monogra- phies which serve to illustrate the later or post-embryonic changes, intervening between the last stages with which the embryologist cares to concern himself, and the point where the organism becomes adult, when it is supposed that the scalpel of the anatomist is all- sufficient in prosecuting farther inquiry. This is unfortunate, since the details of the final metamorphosis of whole systems of organs, even in animals as thoroughly studied as the chick, is in some cases scarcely at all known, or so imperfectly as to be nearly the same as if altogether unknown. The external features of the development of the skeleton of the chick are pretty well known, but the internal and histological changes, and the development of pneumaticity of the bones, quite imperfectly. ; Now that serial sections may be so easily prepared and photo- graphed upon an enlarged scale, it is strange that no one has yet undertaken to prepare sets of uniformly enlarged photographs of series of sections, arranged in a folio in the order in which they were cut, of the most important stages of the development of the chick, and thus supply a more satisfactory iconography of the embryology of this animal than we yet possess. Series of enlarged photographs of serial sections, arranged as suggested, if made with care, would serve almost as well for purposes of reconstruction as the modelling method of Born, or the method of graphic isolation proposed by Kastschenko. It would, in fact, make it possible to inspect series of sections of an organism with as much readiness and as minutely as one is enabled to inspect the successive pages of a _ book. In fact, the topography or relations of the organs, as well as some notion of their histological composition, in an embryo, in Successive planes, could be as readily got at in this way as the text ‘imprinted upon the pages of a book. If thin gelatine positives of such series were properly prepared, protected, and arranged in their proper serial order, in the form of a roll, series of sections could be projected, one section after the other in succession, upon a screen for purposes of lecture demonstration, in a manner far more effective than would be possible with the most complete serial sets of dia- grams.—J, A. R. 1136 General Notes. ARCHAOLOGY AND ANTHROPOLOGY.! ANTHROPOLOGICAL Socrery oF WasHIneron.—Prof. O. T. Mason, of the National Museum, read an interesting lecture on the subject of “the Human Beast of Burden.” He viewed the subject from an anthropologic standpoint. He began with transportation and commerce in prehistoric times. Men and women were the first beasts of burden, and all aboriginal carrying was done on their heads and backs, Even the improved state of civilized society has not extinguished all traces of this, for human carriers are still numerous. Hod-carriers have been but recently, and, indeed, partially, superseded by elevating machines. The great progress of the time has been such, continued Prof. Mason, that no one walks nowadays, unless it is a preferred exercise; horses, steam and elec- tricity lend their aid to whirl people to their destinations. He enumerated the various methods by which the human beasts of burden perform their carrying tasks. First by hand, the right . hand. He said he had examined a great number of savage imple- ments designed to be carried in the hand, and that the proportion of those shaped for use by the left hand was not greater than 1 to 50 ; in no case did he find a left-hand female implement. Then both hands are used, after which the fingers come into play. Illustrat- ing the use of the fingers in carrying he mentioned the summer- resort waiter, who bears his tray aloft on three fingers. The baldric _ is next in order, slung over the shoulder by a strap and hanging on the hip. In this way hunters carry game and travellers carry small satchels. Then, still progressing, goods to be carried are to be hung toa belt. Hanging things on the arm may be called the retail method of carrying, and is used by farm hands, servants, por- progression is to the back, which is the natural carrying- 1 This department is edited by Thomas Wilson, Esq., Smithsonian ; 7 C.

Certain tribes of Indians wear straw rings on their heads to aid in bearing and balancing these great loads. Pockets, remarked Prof. Mason, are scarcely worth mentioning as a civilized means of transportation, although the flowing robes of a Chinaman are capable of concealing at least half a bushel of playing cards, a capacity that deserves passing notice. The carrying power given by these vari- ous modes is augmented by means of combinations of men, in illustration of which the vast works in Egypt and other eastern countries were cited. Men also carry goods by traction, that is, by drawing over the ground. First, the arm alone is used, then a line is fastened to the object and the person. It is held in the hand over the shoulder, wound around the waist or over a pole. The hunter drawing home his game is a primitive example of this means of carrying. Throwing is sometimes resorted to as a means of transportation, of which the method of handling bricks by tossin them from hand to hand isa fair sample. Dirt and excava material were at first carried in sacks, which have been superseded by shovels. The great necessities and the differentiating progresses of civilization for rapid and safe transportation give rise to the professional carriers. THE FIFTH ANNUAL REPORT OF THE BUREAU OF ETHNOLOGY. —This Foame for 1883—84 has just appeared. It contains about 600 pages in quarto form, the report of the Director, Major J. W. : Spe ae filling about 50 pages. The accompanying papers are as oll One on Burial Mounds in the northern section of the United States, by Prof. Thomas. He describes the burial mounds of the Wisconsin district, of Illinois or upper Mississippi, of Ohio, and of the Appalachian district, and elaborates the favorite theory of the Bureau of Ethnology, that the Cherokee Indians were the princi- pal mound-builders of the United States. He reports the discovery made by the exploration of the great and small Etowah mounds in Bartow county, Georgia, and many of the objects found therein are shown by means of illustrations. Chas. C. Boyce, Esq., gives the history of the treaties made between the United States and the Cherokees. He gives the ma- terial provisions of all treaties made, together with their historical data, from that of November 28, 1785 to April 27, 1868. His paper is quite full and seems to have exhausted the subject, It fills prg es. _ Dr. Washington Matthews, of the United States Medical Museum, fornishes the Mountain Chant, a b ceremony belonging to the Nava~ 1138 : General Notes. jos. This is a comparatively new field for anthropological research, and Dr. Matthews has been the principal husbandman. His paper is deserving of high encomium. It is beautifully illustrated, and shows the author to be as equally successful as a poet and historian, as he has been in anthropology and medicine. Rey. Clay MacCauley devotes fifty pages to the Seminole Indians of Florida. He describes their personal characteristics, physique, costumes, and personal adornment; their society and tri life, their industries, arts, and religion, and makes a valuable contribution. Colonel James R. Stevenson might have been well denominated the soul ol the Bureau of Ethnology. He was the discoverer of its protoplasm, and was its Executive officer during the greater part of its existence, until his death in August, 1888, at the Gilsey House, New York City. This is no place for panegyric upon his abilities. Whatever of honor and credit, history shall mete out to him for his anthropologic researches among the Zunis and other Indians of the interior and western United States, must be fairly divided with his wife. She accompanied him in all, or nearly all, his explora- tions, and her zeal, ability, faithfulness and address in procuring the more difficult secret information concerning the inner life of Indians and Indian women, of their mythology, of their religious societies, of the ceremonies by which they were carried on, can never be fully portrayed or thoroughly understood. His contribution to e present volume is the “Religious Life of the Zuñi Child. Her paper is illustrated by four full-page chromo-lithographi¢ plates, illustrative of the masks, dresses, and other objects used in the ceremonies which she describes. SOME SUPERSTITIONS OF THE BAHAMA NEGROES.—Some years ago, while in the employment of the Bahamas Government, I spent a month in exploring the island, or rather islands, of Andros, m the west of the Bahama archipelago. The negroes of the northern part of Andros are physically the finest in the colony, and are also superior in other ways, in spite of their bad repute in Nassau. {t is said that during the Indian wars in Florida numbers of Indians = made Andros their temporary home, but they appear to have mixed _ very little with the negroes. One old man, however, who was my host during my stay in the island, says that his grandfather was an Indian, and his appearance bears out the statement to some extent, his color being of a reddish brown, his features Indian in their cast, and his hair not woolly but in long curls. : The settlements in Andros are all along the East coast, the inte- rior being a great swamp, with occasional ponds, and island-lik prb of coral-rock, covered with pines, scattered throughout it. I found that many of the negroes curious superstitions oe respecting the interior, which they rarely visited. One ony : Archeology and Anthropology. 1139 told me that the pine woods were inhabited by creatures called “ Yayhoos” (Query, has the name come from Dean Swift?), big, black, hairy beings who walk about in “schools,” the biggest first, “and if they catch you, they tear you.” The only way of putting these creatures to flight was by waving a torch at them. There were also small, black beings like little men, who were called “ little people,” who lived in the branches of the pines, and if one pointed a finger at them, one fell down a cripple. These had been seen by the father (of course, dead) of my informant. These superstitions would appear to relate to the gorillas and monkeys of the West Coast of Africa, and to have been handed down from the original African slaves to their children. The pine woods were also said to be inhabited by “ mermaids” of both sexes, the name being used indiscriminately, who occupied themselves in the traditional way combing their hair. An eerie story was told me by my old host. Once, in his father’s time at one of the southern settlements, a woman left two of her children at home while she went to the fields. On her return, she found that the younger, a mere infant, had disappeared, and that the elder could not say what had become of it. The well was searched, and parties of men hunted through the bush, but for some time without result. On the third day, however, some of the men heard cries, and forming a ring they gradually reached the spot whence the cries came. There they saw an awful sight; the missing child was held by a thing without head or arms or legs, and more like one of the great, brown ants’ nests than iter else. When it saw the men, the thing appeared to be afraid, anc threw the child on to a mass of *‘ love-vine,” trailing from a neigh- boring tree, and then made off into the bush. The men, horribly frightened, took to their heels, except one, who took up the child from the ground to which it had fallen, and carried it home. The child’s body had become like jelly, and it only lived a day or two, This story appears to be “ made out of whole cloth,” and the con- ception of an ant’s nest, headless, eyeless, limbless, yet capable of seeing, moving, throwing, is grotesque even for a negro imagi- nation The negroes of the Bahamas show far fewer effects of white influ- ence than those of the United States, or even of the other West India Islands. Even in New Providence they have customs which, I fancy, are not found in the South, such as the fire-dances, the election with great ceremony of queens of the Congo, Yuruba, and Ebo tribes, ete. A belief in Obeah is prevalent, and probably also Voodooism, but it is excessively difficult for a white man to obtain any information on the matter, in New Providence, at least. In Andros there might be fewer difficulties in the way, for the con- fidence of the negroes there is easily won, if they be well treated. 1140 General Notes, MICROSCOPY .!

Microscopy. 1141 porate out the requirements to be fulfilled by such reagents, lays own the principles by which one should be guided in selecting them, and concludes by giving a method which has proved to be eminently satisfactory. Rules.—(a) For fixing tissues it is important to use reagents that do not form tissue-like precipitates with protoplasm. This require- ment is met by chromic salts, sulphate of copper, sublimate and some other salts. Preparations in chromic salts, when transferred to alco- hol, should be kept in absolute darkness (H. Virchow), until the fix- ing reagent is removed so far as possible. (b) All reagents which transform protoplasm into tissue-like forms, as, e.g., chromic acid, should be avoided, or their application must be controlled. (c) Fixing fluids should contain an organic acid, e.g., acetic acid, which changes nuclein into an insoluble state. The acid must be used in a diluted form, as nuclein is dissolved in strong acids. The time of action must be short, as the long-continued action of even a weak acid dissolves nuclein. (d) It is desirable that the fixing fluid should contain alcohol in a small quantity. - Strong alcohol dehydrates and induces changes in the protoplasm. Kultschitzky’s Fluid.— Add, ad libitum, pulverized bichromate of potassium and sulphate of copper to alcohol (50 per cent.). Keep in absolute darkness twenty-four hours. A transparent greenish- yellow fluid is thus obtained, which is to be acidulated before use with acetic acid (5 to 6 drops to 100 ce.). Method.— Place the object in the fixing fluid for from twelve to twenty-four hours, according to its size and hardness, and keep in the dark ; then transfer to strong alcohol. After twelve to twenty- four hours the preparation is hard enough for cutting. Conservation. =Kultechiteky thinks that for conservation only such fluids should be used as produce no further changes in proto- plasm after it has once been fixed. As alcohol, Miiller’s Fluid and other fluids in common use do work changes in the tissues, ee pernliaky recommends keeping preparations in ether, xylol, or Accessory Nuclei (Nebenkerne, Paranuclei).—Dr. Gustav Platner has been for some years en with the problem of the origin and meaning of accessory nuclei in gland-cells. The results of his work have not yet been published, so far as I am aware; but some — of his methods of study have been given in the Zeitschrift fiir wis- ifiliche Mikroskopie, Vol. IV., No. 3, p. 349. Flemming’s chrom-osmio-acetic acid is the best hardening, or “ fixing” medium. This mixture may sometimes be modified to advantage by dimin- ishing the quantity of acetic acid and increasing that of osmice acid. en the accessory nucleus forms a compact mass, as In reptiles 1142 General Notes. and many anura, a mixture of picric acid and sublimate gives good preparations. led to the introduction of a new stain, for which Platner suggests medullary sheath uncolored. Used at its full strength it stains other tissues, but with less intensity. An over-stain is easily reduced by dilute ammonia (five or six drops to a watch-glass full of water), or, preferably, by carbonate of — lithium, diluted ad libitum. A pure and intense nuclear stain may be thus obtained. Treated in this way, the accessory nuclei are stained in varying degrees of intensity, according to the stage of their development.! i It is a remarkable fact that these accessory nuclei, soon after their formation, become non-receptive to safranin or Victoria blue 4 R, while remaining stainable with nucleus-black. It would seem, as Platner remarks, that chromatin is composed of two substances, one of which is affected only by certain nuclear stains, while the other is receptive to a large number of stains, and especially so to nucleus- black and hematoxylin. Sections from preparations in Flemming’s fluid may be left twenty-four hours in a dilute solution of nucleus-black. The time of exposure to the decoloring fluid will vary according to the inten- sity of the stain received and the end to be reached. ‘The stain is permanent and well adapted to photographing. The Eggs of Ascaris megalocephala.—Platner recommends heat- ing to 50°C., for twenty to forty seconds, then hardening ia ascend- ing grades of alcohol. This method has the great advantage of killing instantly without injurious effects, and leaving the nuclear figures in a better state of preservation than can be reached by any other method hitherto used. The egg-sacks are placed in a test- tube plunged in a dish of hot water. This method will undoubt- edly be useful in other cases. 1 Accessory nuclei arise from the chromatin of the nucleus, by a pro — cess of budding, and their development may be induced by starving tne nimal the sixth or seventh day, in the case of the salamander, Scientific News. 1143 Bobretzky, Hertwig, Reichenbach, and others who have employed the method of heating, have subjected the eggs to a heat of 80°C.,, or more, and for a considerable length of time. Platner is unques- tionably right in attributing previous failures in the use of this method to the unnecessarily high temperature employed. Max Schultze has shown that protoplasm is killed and stiffened at 50°C., and the use of a nearly boiling heat is therefore quite as unnecessary as it is harmful. PARAFFINE PREPARED FOR RIBBON-CUTTING.—Dr, Spee? finds that paraffine prepared in the following manner is best adapted to ribbon-cutting :— Take paraffine, which melts at about 50°C., and melt it over a spirit lamp. Keep hot for from one to six hours, until assumes a brownish yellow color, like that of yellow wax or honey.

S. Williams, of Cornell University, publishes a letter, in which he says that Robert Bakewell gave “a remarkably clear conception of the elements of the theory which Charles Darwin has made famous, almost thirty years prior to the appearance of ‘The Origin of Species.’ ” At first he gives some notes about artificial selection by R. Bake- well, which contain nothing new; artificial selection having been use from the oldest historical times. Then Mr. Williams continues, stating that Mr. Bakewell applied this principle to explain the appearance of new forms of Mollusca. But Mr. Bakewell’s remarks have nothing to do with natural selection whatever. He simply says that forms are changed when brought into different conditions. This is Transformism or Lamarckism, but not Darwinism ! Mr. Williams seems to ignore the fundamental difference between these two theories, in spite of the numerous recent able [discussions on this subject—G.

NATURAL aa ASSOCIATION OF STATEN IsLanp.—Feb- ruary Ilth, 1888.—On motion of Mt Hollick the following preamble and resolutions were adopt hereas, Our attention has been called to the title of a bill recently introduced in the Assembly, designed to allow the shoot- ing of ipren on i and Staten Islands during the month of Pheer. Such “legislation would be a gross injustice to our Island, and would be a source of needless analy and destruction to our birds.

There were found to range from 44° to 58° F., the colder water being due to a less rapid flow and conse-. 1146. Proceedings of Scientific Societies. quently longer exposure at the springs’ vent to the’ atmospheric influence. These springs, known as the “ Boiling Springs,” doubtless arise from below the impervious beds of clay, which may be seen outcropping along the sides of the gulches in the neighbor- kood ‘washed out by freshets. While it seems unlikely that they issue from such a depth as sixty or eighty feet, which is assigned by Guyot.as the limits of the zone of invariable temperature at our latitude, it is quite certain that points of origin are deep seated and almost, if not entirely, removed from superficial influence. The observation of Mr. W. T. Davis upon the Summer temperature of the €love Valley springs corroborates this. He found that to be from 53° to 54°; almost identical with the Winter temperature of these opines at the coldest period of the season. The water flowing with is elevated temperature nourished an abundant growth of the common fresh water alga (Conferva vulgaris Rab.), which in turn supported in its thick and confused clusters numerous diatoms and infusoria.. The green stems of a species of Veronica, too immature for determination, flourished abundantly in the tepid rivulet escap- ing from the tiny pools, while within a few feet last Summer's grasses were frozen in a crust of ice. | > Mr. Wm. T. Davis read a portion of a letter from Mr. Aug. R. Grote. The extract is as follows: In 1856 I found Clematis ochroleuca growing on Kellett’s Hill, near Egbertville, on the Southern slope near the top. My specimens went to the late Hon. Geo. W. Clinton, botanist, of Albany. I also collected a specimen of the fork-tailed flycatcher, Milvulus tyrannus, near our farm o Hill Park, towards the south-west side of the Island. ı March 10th.—Mr. Arthur Hollick read the following notes, illustrated by drawings and dried specimens :— l During the Autumn of 1881 a species of sedge was found in company with Callitriche verna and Dichelyma capillaceum growing on.the bottom of one of the springs near the present site of the S. I. Water Supply Co. It was proliferous, and showed no signs of. either perfect flower or fruit, but as it was rather late in the season a more favorable time was awaited in which to collect and study it. spring was deep, with walled sides and a clean sandy bottom and was never known to freeze, even in the severest winter. The ap was entirely aquatic—no part of it ever growing to the sur- ace of the water. During the succeeding year it was visited from time to time in the hopes of obtaining either the flower or fruit, but without success. Specimens were however collected with aborted proliferous spikes, and it was finally admitted provisionally by Dr. Britton and myself into the Flora of Richmond county, in the appendix for 1883-84, under the name Heleocharis prolifera Torr (?). _ Smee then it has been kept under constant scrutiny, but has never been found with flowers, and we were forced to conclude that it did- Proceedings of Scientific Societies. - 1147 not produceany. It was naturally with some trepidation that it was determined to be this plant, as its habitat is given by Chapman, in his “ Flora of the Southern States” to be from Florida to N: Carolina, and from there to Staten Island seemed a very extensive jump for the plant to take, without any intermediate locality from which it could have spread. Within the past six weeks, however, we have received specimens from the neighborhood of Trenton, N: J., which is a little more encouraging. It is well also to bear in mind that the place which this southern plant secured from its home so far north is just such a one as we would expect, namely, a perennial spring, which never freezes and in fact which maintains a constant temperature throughout the year of about 53°. So far as known, it failed to secure a foothold at any other locality on the Island, and the specimens which are now in our herbaria are pro ably the only ones which will ever be seen from here, as the spring as become silted up and all signs of life obliterated. ! I was interested to find the following note in Dr. Torrey’s monograph on the Cyperaceee of N. America, p. 815-16: “ Among my undetermined Cyperacez is a species of Eleocharis from the Southern States, which I have never been able to obtain with mature fruit. * * * * The spike is ovate. and compressed, but instead of producing flowers it throws out a tuft of long filiform peduncles or rather culms, one from the axil of each scale, which strike root into the mud or float on the surface of the water and likewise bear proliferous spikes. * * * * I am inclined to consider this species as distinct from any other described in this monograph. It may be distinguished by the name of E. prolifera.” , Again, in the Columbia College Herbarium, accompanying a specimen labeled Æ. prolifera, is a note by Dr. Torrey, which reads: “ This may be a state of my Chetocyperus baldwinnii and the plant referred to in Baldwin’s notes. * * * *” 2 Careful comparisons have been made between our specimens and those in the Columbia College Herbarium, under the names Heleo- charis baldwinii Torr. and H. prolifera Torr., but our material is too imperfect to definitely determine just where it belongs. e specimens, while showing the general characteristics of the above- mentioned species differ in having a stiff jointed woody rachis, along which the spikes are arranged alternately, and at the summit of which they are closely appressed into a somewhat. imbricated el stolons which bear the proliferous spikes at irregular intervals. Mr. L. P. Gratacap presented a nest of the Baltimore Oriole, suspended from the branches of acherry tree. One side of the nest had 1 been supported by means of strands of worsted attached to a branch considerably above the main support, acting in the nature of a guy rope to steady the structure. 1458 Proceedings of Scientific Societies. May 12th—Mr. Wm. T. Davis read the following ento- mological notes of local interest. A very small straw-colored cricket was discovered last August on the borders of the salt meadow at Great Kill. It was chiefly observed on the stems and leaves of the “high tide bushes” (Iva frutescens), and was difficult to capture owing to its shyness. When stridulating the sound produced was quite metallic in tone and may be likened to that well-known silvery sound of oxygen escaping bubble by bubble in a water bottle. This insect has been identified as Anawxipha eaigua Say., and seems to have never been reported before from north of Maryland. The “ earwig ” (Anisolabris maritima), common several years a on the shore of Camp Washington, before the advent of the railroad, as noted in the proceedings for January, 1887, was discovered the ast Summer at the other end of the Island, on the shore at Totten- ville. They live under stones and pieces of wood just at high water mark. On an open sandy spot near Tottenville a species of “tiger beetle” (Cicindela modesta), has been observed for the past several years, and last fall a few specimens were seen at Watchogue. These insects have been searched for at intervening points, where the same natural features are present, but have only been discovered at those mentioned. A specimen of Erebus odora, the largest species of noctuid moth to be found on the Island, was presented to the Association. It was taken during last September while flying about a room, at New Dorp, by Miss M. Britton, and is in good condition. Two other specimens have been captured on the Island during the last few years in the month of July, one at “sugar” and the other in 8a barn. All of these moths,are females, as indicated by the three ula. Mr. Samuel Henshaw reported the discovery of a wild rabbit's - nest in a small pile of tobacco stems thrown out of a grape house. Its position was extremely exposed, the ground being perfectly bare old. The strong odor from the tobacco stems would greatly aid in protecting the nest from predatory prowlers, and it was sugg that the situation may have been chosen for this reason. Proceedings of Scientific Societies. 1149 . June 9th.—Mr. Samuel Henshaw submitted the following notes: The late spring of this year prevented the buds of the forest trees unfolding at their usual time, but when they did begin, their growth was astonishingly rapid. The horse chestnuts had finished their year’s growth in nine days, the beech in about ten days, and other trees correspondingly rapid, as if nature was trying to make up for the delay. Indeed, I have noticed that no matter whether it is an early or late spring, by the first week in June all seasons are nearly alike. The blizzard played queer freaks with the hardy trees; some Japanese maples, that have stood the last twelve years without any protection, have suffered—one is dead and the others have lost a Some trees look as if the bark on the windward side had street, N. Y., and at York, Penn., it had been observed feeding on potatoes. It has been found in numbers in cellars and cisterns on Staten Island. are of considerable interest. Thus, there are 1,264 species and varieties enumerated, all of which are in our herbarium, with the exception of about 30, which have not yet been collected, although reported upon good authority. These species are distributed among 511 genera and 111 families. 1225 are Phanerogams or flowering plants and thirty-nine are the higher Cryptogams—ferns and allies. The Angiosperms number 916, of which 377 are Polypetalous, 405 are Gamopetalous and 134 are Apetalous. The Gymnosperms number six. The Dicotyledones number 916 and the Monocotyle- dones 303. - Ifthey are divided roughly into herbs, shrubs and trees, we have 1,094 herbs, eighty-eight shrubs and seventy-two trees. Considering them as native and introduced the numbers are about 1039 native and 225 introduced. The largest family is Composite, with its fifty- 1150 ` Proceedings of Scientific Societies. one genera and 148 species. These latter include twenty-seven Asters and nineteen Golden-rods. Grasses—forty-three genera and 115 species, including nineteen Panicums. Cyperacee or sedges— ten genera and eighty-one species, including forty-three Carex. Leguminose—twenty-one genera and fifty-four species. Labiatæ— twenty-five genera and forty-eight species. Rosaceee—thirteen nera and forty-seven species. Caryophyllese—fifteen genera and thirty-eight species. Scrophularinese—thirteen genera and thirty- two species. Ericacee—fifteen genera and thirty-one species, including eleven which are picked under the common name of “Huckleberry.” Cruciferee—fourteen genera and thirty-one species. Ranunculaceæ —thirteen genera and thirty-one species. Polygonacee—three genera and twenty-seven species, including nineteen Polygonums. Lilacese—sixteen genera and twenty.five species. Orchidacee—twelve genera and twenty-four species. Umbelliferse—seventeen genera and twenty-two species. In the erns we have thirteen genera and twenty-eight species. There are twelve Violets, twelve Oaks, eleven Willows, five Hickories and four Pines. Amongst the large number of plants worthy of particular mention is the Clematis ochroleuca Ait., of which an account was given in the proceedings for June 11th, 1887. The “ Crane-fly Orchis,” (Tipularia discolor Nutt.), although accounted a very scarce plant, is abundant throughout nearly all our deep wet woods. Almost without exception all the most troublesome weeds have been introduced, such as the “Pig weeds,” “ Wormseeds,” “ Amaranths,” “ Crab ” “ Wild Carrot,” “ Ox eye Daisy,” etc. Some of the worst weeds have spread so rapidly in recent years that although they are already pests yet no common name has been invented for m. For instance, I can well remember when the first few plants of Galinsoga parviflora Cav., made their appearance in this region. It is now to be found nearly everywhere at this end of the Island and is spreading with amazing rapidity. “Trailing arbutus” has almost become a thing of the past, although a few patches still exist, which have not yet been destroyed by “arbutus parties.” General memoranda upon our flora will be found in the proceedings for June 13th, 1885, and an account of our forest growth and the few large trees yet remaining, in the proceedings for February 12th and March 12th, 1887. Memoranda have been accumulating since the fourth appendix to the flora was issued, which will probably necessitate a fifth appendix at the end of the present season, so it will be seen that the work of the botanical collector on Staten _ Island is not by any means completed, especially when it is remem- _ bered that most of the lower orders of eryptogams have hardly been touched. The Diatoms are, however, being catalogued by Mr. E. A. Schultze, and a list of the sea weeds by Mr. Nicholas Pike, | _ 1s ready for the printer, while a good preliminary list of the mosses Proceedings of Scientific Societies. 1151 is in preparation ; but the Liverworts, Lichens, Desmids, Fungi and Protophytes await the future botanist’s attention. October 13th—Mr. Wm. T. Davis presented natural-sized drawings of leaf forms and fruit of the hybrid oaks found near Richmond Valley, with the following further remarks upon the same :— Since the September proceedings were printed, the oaks near Richmond Valley have been visited several times by Mr. Hollick, Mr. Gratacap and myself, and they have proved of so much interest that a detailed description of at least some of the trees may be worthy of record. Nineteen oaks have so far been discovered, each tree having a sort of individuality, and their consideration with a view to clear- ing up the mooted points is no easy matter, but one that will at least require an extended period of careful observation. Some leaves represent what has been considered as Quercus the mid-rib. The character and position of these oaks wou indicate that Q. phellos with Q. palustris are the parents and this In heterophylla the average diameter of the empty cups is about three m. m. more than palustris and the heighth of the nut is also greater in comparison to its breadth. In phellos the acorns are still smaller than in palustris, but it is an interesting fact that the roportions come closer to those of heterophylla. In Chambers, ncyclopædia it is stated that in hybrids “ valuable results are often | obtained as to size and abundance of fruit.” LIN DES., Abbott, C.C., Evidences of Antiquity of Man in Eastern North America, i Aboriginal Monuments, Protection f, 231.
