TODD. os eee a name seems best to express the character of certain strange works noticed by the writer upon some of the con- spicuous hills of Southeastern Dakota. The term mosaic, though describing better than any other word their structure, may sug- gest greater delicacy than they possess, but the qualifying epithet sufficiently corrects it. A typical example, and the first to come to the writer’s knowl- edge, was found on the summit of Keya Kakop, or Turtle point, three miles north of Wessington springs in Jerauld county. The point is a high promontory-like hill standing out on the western edge of the James River valley, above which it rises nearly 500 feet. It is the northern end of a high ridge of drift constituting a well washed interlobular portion of the principal moraine. A view of Turtle point and a portion of the ridge from the north- west is shown in Fig. 1. Upon the highest portion of the point ` ~is a low broad mound built of earth, perhaps fifty feet in diame- ` ter andthree or four feet high. It does not differ materially from many that are found on the summit of bluffs along the James and- Missouri. Its chief attraction is the gigantic figure of a turtle upon its southern slope, as is shown in Fig. 2. This figure is formed of boulders, four to six inches in diameter, quite closely — and regularly set, so as to describe its outline. The head, legs < andtailare extended. Its general appearance, position and struc- ture are shown in Fig. 3. Visitors to the locality will also- notice a rude human figure, sketched with similar material, on the south-west side of the mound as shown in Fig. 2, but it is cón- fessedly the vork of an earl owner of the | . VOL, XX —No, I, To ome ae 2 Boulder Mosaics in Dakota. [ January, not informed of the fact its recency would be apparent from the pebbles comprising it lying on the surface of the ground, while those forming the turtle are half imbedded. That it is not of the same origin as the turtle is further indicated by the represen- tation of the legs and arms by single rows of stones. The locality was first visited by the writer in 1881, and the figures were intact when seen again in 1883. The figure is about fifteen feet in length from tip of tail to front of head. A little pile of stones lies a short distance in front of the head. This work, interesting as it is, sinks into insignificance when compared with a similar work upon Paha Wakan, or Medicine hill, near Blunt, in Hughes county. This hill is also a high inter- lobular portion of the principal moraine, and presents the same _ general features as Turtle point, as will be seen in a sketch of it, from the east, in Fig. 6. It rises above the surrounding plain about 200 feet, and nearly 400 feet above the adjoining valley of Medicine creek. Its summit is flat and includes many acres. Granite and limestone boulders abound in profusion. Tipi-rings, 2. e., circles of boulders which were used in holding down the covering of the conical tents used by the Dakotas, are very abun- dant upon the summit. A few mounds of ordinary size are scat- tered in no apparent order. Near the north-western angle of the summit platform is the gigantic figure represented in Fig. 4. Its length measured roughly along its central line, following the crooks, is 120 paces. The general form, with length, breadth and number and shape of crooks, are as faithfully represented as __ a hasty sketch could give. The boulders composing it are from ` six to twelve inches in length, and are laid much less closely than in the turtle. The direction of its northern half is N. 18° . The presence of the mound at its side seems to be acci- dental. The head is more carefully represented in Fig. 5, where an attempt is made to express the shape, size and position of the boulders composing it. The eyes are much more expressive than it would at first seems possible to make them with such material. They have literally a “sony stare.” They are formed of two oblong - boulders nearly a foot in length. The angular head and heavy body suggest the rattlesnake as the designer’s model, but there is no clear representation of the rattles. Perhaps that was beyond the artist’s inventive power. Atc, in Fig. 4, the boulders have evidently been displaced, probably by water or frost action, as 1886. ] Boulder Mosaics in Dakota. 3 that portion is on an inclined surface. This gigantic serpent was in good condition when seen in 1883. An examination of similar localities over all Southeastern Dakota has failed to discover any other similar representations of animals. Numerous rude sketches of animals on a smaller scale are found near Pipestone, Minn., chipped or pecked on the smooth surface of the red quartzite. Some of the best of these are exhibited in the Minnesota Geological Report, Vol. 1. In these the turtle is a favorite figure, but none are as symmetrically represented as in the one on Turtle point. No serpent is repre- sented among them. Similarly made figures, but quite imperfect, were noticed by the writer on Wolf creek, south-west of Bridgewater, Dak. But although no more animal figures have been found, a few other similarly constructed works have been noted. Upon Indian hill, north-west of Valley City, is a rectangular figure between two mounds which may be natural. The sides are remarkably straight and parallel, and the stones, which are four to twelve inches in diameter, are quite regularly laid. The ends are rounded a little. Its form is shown in Fig. 7. It is eighteen paces long and three paces wide. The direction of its sides is N. 78° E. A number of the stones composing it had been lately displaced in 1882 when the writer visited it. The holes in which they had lain were fresh and showed their form clearly. Upon a high broad terrace of Crow creek, a few rods back and east from a remarkably fine spring which is at the foot of the ter- race, and about a mile north-west of the town of Waterbury, is found a somewhat similar figure on a much larger scale; more- over it is incomplete and somewhat irregular. Its outline is shown in Fig. 8. It eastern side is ninety-two paces in length and is directed N. 2° E. The north end is curved slightly, but lies nearly at right angles with the left side, which is directed N. 15° E. Ata@isan opening which may represent a gateway, - eo as an oblique line of stones, sufficient in length to close it, is at one end. Near it and at various other places are small circular pits, two to four feet across. No pains was taken to locate them accurately, as it was thought that they had no oy connection with the lines of boulders. i The gap at d was probably caused by some recent removal ot the boulders for use in forming some tipi-rings not faraway. At a 4 Boulder Mosaics in Dakota. (January, 6 is a circular pit with boulders on its sides and a pile of pebbles in its bottom. Atc is a triangular pile of stones about three feet on each side. The southern ends of the sides are not far from the side of a ravine. A more careful examination would prob- ably discover other interesting and perhaps more significant relations. According to Mr.T. H. Null, of Waterbury, who has seen it, there is, on the S. W. 1%, S. 28, 109.66, a cross formed of two lines of boulders. One four rods long is crossed at right angles by an- other one and a half rods long.

On the right bank of Elm river were two quite con- spicuous mounds, 270 paces apart, upon two symmetrical knolls. Beginning at the top of the north-western one, a line of bones extended over the center of the other, and 146 paces beyond, - where it ended in a small pile of boulders. The bones were mostly the leg bones of buffalo set up in the ground like stakes. That was before the land was in market. Ere this the plow of the white man has probably removed all trace of them. A few years more and the more enduring “ boulder mosaics ” will prob- ably help to form the stone wall of some enterprising settler, as careless of the sacred associations: attending them as the Turk who builds the fragments of ancient temples into his hovel.

BY E. LEWIS STURTEVANT, M.D. HE dandelion is a plant of northern climates, especially found growing amidst the herbage of meadows, and as a weed in gardens. Its common name is a corruption of dent de leon, a word which is met with in the Welsh Dant y Llew of the 13th century. Its vernacular names in various languages have usually reference to the peculiar indentation of the leaves, or to some other resemblance or character of the plant. By commen- tators it has been identified with the aphake of Theophrastus, æ in composition signifying absence of, and pake lentils, or the name perhaps signifying that the plant can be used as a green before lentils appear in the spring (?); the amdudeia of Pliny may suggest the scattering of the seed, améu/o meaning the going backward and forward, but some commentators assign this name to the wild endive or chicory; the edypnois of Pliny is but doubtfully identified with our dandelion, and appears to be de- rived from two Greek words signifying sweet breath, and may refer to the sweet smell of the flowers. Pinzeus, 1561, calls it Dens Leonis, Dens Caninus, caput Monachi, Rostru porcinum or Ambubeia, the aphake of Theophrastus; by the French, Pissenlit or Dent de Lyon ; by the Germans, Pfaffen roerlin. Pena and Lobel, 1570, give additional names of Urinaria, German Korlkraut and Phaffen- blat, Belgian Pappen cruyt, English Dent de Lyon. The modern vernacular names are: English dandelion, swine's snout (Prior); France pisseniit, dent-de-lion (Vilm.); German /owenzahn (Lenz) ; Flanders molsalaad (Vilm.); Danish moelkebtte (Vilm.) ; Italian tarassaco (Lenz), dente de leone, virasole dei prati (Vilm.); Span- ish diente de leon, Amargon (Vilm.); Greek agriomaroulia (Sibth.), — pikraphake (Fraas); Japanese fosei or usually fudsina or tsugumi | gusee or tampopo (Pick.). - Bauhin, in his Pinax, edition of 1623, enumerates two varieties of dandelion, one the Dens Leonis latiore filio carried back in his synonomy to Brunselsius, 1539 ; the other, Dens Leonis an- — gustiore folio, carried back in like manner to Cesalpinus, ale The first kind, he says, has a large and a medium variety, the leaves sometimes pointed, sometimes obtuse. In the Flore Natu- — relle et Economique, Paris, 1803, the same varieties, apparently, — are mentioned, one with narrow leaves and the other with large — 6 A Study of the Dandelion. [January, and rounded leaves. In Martyn’s Millers Dictionary, 1807, the leaves of the dandelion are said to vary from pinnatifid or deeply runcinate in a very dry situation to nearly entire in a very moist one, generally smooth, but sometimes a little rough, and Leonto- don palustre is described as scarcely more than a variety, as vary- ing very much in its leaves which have few notches or are almost entire, the plant smoother, neater, more levigated and more glau- cous than the common dandelion. In Geneva, N. Y. on the grounds of the New York Agricultural Experiment Station, a large number of varieties are to be commonly noted, both in the habit and appearance of the plant and irrespective of difference of soil or exposure, as varieties may readily be separated whose roots are intertwined. Some plants grow with quite erect leaves, others with their leaves closely adpressed to the soil; some have broad, others narrow leaves; some have runcinate leaves, others leaves much cut and almost fringed, and yet others the leaves nearly entire ; some have almost sessile leaves, some have smooth leaves, others roughened leaves; some have thin, others thick leaves; some as varieties grow to a larger size, others are always dwarfer ; some have an open manner of growth, others a close, etc. The use of the wild plant as a vegetable seems to have been common from remote times, but its culture is modern. In 1836 a Mr. Corey, of Brookline, Mass., grew dandelions for the Boston market, the seed obtained from the largest of the wild plants (Mass. Hort. Soc. Trans., 1884, 128); in 1863 dandelions are de- scribed among garden esculents by Burr (Field and Gard. Veg. of America, 345), but the context not indicating any especial _ varieties ; in 1828 Fessenden (New Am. Gardener) says the wild plant is used but never cultivated. In 1874 the seed appears for sale in seed catalogues (Briggs Bros. Cat., 1874), perhaps earlier, _ and the various seed catalogues of 1885 offer six names, one of which is the “ common.” In England, dandelion culture is not mentioned in Mawe’s Gardiner, 1778, nor in Martyn’s Millers Dictionary, 1807; the first notice I find is in the Gardeners’ Chronicle, 1846 (p. 340), where an instance of cultivation is noted, the herbage forming “a beautiful and delicate blanched salad.” In 1880 its culture had not become common, as this year its cul- tivation in France, and not in England, is noted (Jenkins Jour. R. A. S., xvi, 94). In France, Noisette, 1829 (Man. du Jard., 1829, 356) gives cultural directions, and says the wild plant fur- Mi etc c roy Ab. Ae RY Ay ga Sie ie euch an 1886. | A Study of the Dandelion. 7 nishes a spring pot-herb; the plant is, however, not mentioned in L Horticulteur Francais, 1824-5, nor in Nouveau Dictionnaire du Jardinage, 1826. Vilmorin (Bon Jardinier, 1882) states its cul- ture in France as dating from 1868, and the firm of Vilmorin, Andrew et Cie in 1885 offer four sorts of seed, one, the “improved moss” as new. In Vilmorin’s Les Plantes Potageres, 1883, two forms are figured, Pissenlit ameliore a cceur plein and Pissenlit ameliore tres hatif. The first of these is named in Album de Cliches, Pissenlit ameliore frise, and a fourth name or third form is figured, the Pissenlit mousse. 1. The type of the Pissenlit mousse can be readily found among the wild plants of the station grounds, very closely resem- bling Vilmorin’s figure in every respect when growing on rich soil except that the leaf divisions are scarcely as much crowded. 2. The type of the Pissenlit ameliore a cceur plein is perhaps to be recognized in Anton Pinzus’ figure, 1561, and is certainly to be found growing wild at the station. 3. The Pissenlit ameliore tres hatif is figured in 1616, the resemblanoé between the two figures, the one by Dodonzus and the other by Vilmorin, is very close. It is also to be found growing wild on the station grounds, The influence of rich soil and protected growth upon the dan- delion is to give increased size and succulency to the plant, and to thicken the branching of the leaves, in the direction of answer- ing the description of a cwur plein ; but this influence appears to be limited by the heredity of the plant, as the types do not react to an equal extent. This fullness or hearting in No. 2 seems to come from the strong tendency in plants of this type to divide the root into a group of crowns; the leaves, also, in rich soil, grow rather upright with the upper portion curving outwards, giving a curled appearance to the plant, and thus justifying Vil- morin’s alternate name “frise.” The No. 3 form is more succu- ent in rich soil than the others, attains size distinctly earlier, is less crowded and less upright in growth, and in some cases is very closely adpressed to the ground. No. 1 type does not in all cases seem to be a depauperate form, as it is found on fertile soil along with the rest, it is usually small, but in some instances — is of fair size and quite bunchy growth. A form with nearly entire leaves has not yet reached culture under a distinct name; this type is distinctly smaller than the rest, and some plants have 8 A Study of the Dandelion. [January,. sessile and thickened leaves, other plants long petioled and spat- ufate-like thin leaves. In all the forms some plants may be looked for with hairy and roughened leaves. In view of the limited extent of the present culture of the dan- delion, and the short time since its cultivation was first attempted, as well as to the fact that its present culture about Geneva seems unknown, it seems unreasonable to infer that our plants are escapes from cultivation, and much more-so when it is consid- ered that these same described types are common elsewhere in Western New York. If not escapes from cultivation the infer- ence seems strongly established that our cultivated varieties did. not originate under cultivation, but are simply selections from wild types. If this be granted it may be legitimately questioned whether other of our cultivated form-species in other plants are not likewise of natural origin. _A careful investigation into the history of the origin of our cultivated varieties fully justifies the statement that I have as yet secured no data which justifies the belief that form-species in cul- ture are other than of natural origin, and I have secured much evidence ir favor of the view that form-species are introductions from natural variations. Before, however, such a radical belief can receive countenance, much must be done in the herbarium study of varieties as collected from various sources, in order that we may have wild forms to which our cultivated types can be re- ferred. Our so-called modern vegetables, introduced as novelties, often seem to be such only because we are unfamiliar with what our predecessors possessed. Thus the figure that Pinaeus gives, _in 1561, of a lettuce answers to our stone tennis-ball variety as closely as do the figures in our seed catalogues to the varieties whose name they carry; the deer-tongue lettuce introduced as a novelty in 1883 seems nearly identical with the Lactuca folio oblongo acuto of Bauhin’s Prodromus, 1671; a large number of our capsicums or peppers seem to be identical with the varieties figured in Hortus Eystettensis, 1623; new types of squash fol- lowed the appearance of the Valparaiso from Chili in the early part of the present century, etc., etc. Under the hypothesis that the form-species of cultivation are _ originally from nature, we can explain the permanency of these form-species, and their resistance to change from cross fertiliza- tion, the tendency seeming strongly towards trueness to type, and the purging themselves from contaminations unless restrained 1886. ] A Study of the Dandelion. d. perhaps by human selection. Thus two form-species of maize, when crossed, have not produced intermediates in their crop, but the parent types without intermediates, and the continuous plant- ing of the progeny tended toward a complete separation into the original types. Various crossings of a like kind, made at the Experiment station, seem confirmatory of this view, and seem to suggest in addition that seeming sports are often the result of atavism. Appended are a few of the variations which are to be found in the leaves of the dandelion, selected rather as representative than as exceptional. A series could ‘readily have been selected show- ing a passage from one type to another, as frequently leaves of quite different appearance appear on the same plant. * Varieties of Dandelion leaves. `" 10 The Relations of Mind and Matter. [January, THE RELATIONS OF MIND AND MATTER. BY CHARLES MORRIS. (Continued from p. 1159, December number.) UCH space might here be given to the numerous and impor- tant observations on hypnotic phenomena published of late years, but we must confine ourselves to the mesmeric experiments of the Psychic Society. These experiments were very numerous, and were conducted with such extreme care that their evidence in favor of direct mental communication seems incontestable. Their results were of a more declared character than those of the thought transfer experiments. Not only thought transfer but mind control appeared. The active seemed to take full posses- sion of the passive mind, and this often with a considerable dis- tance intervening between the parties. The thoughts of the one mind appeared to infuse themselves into the other, driving back its own consciousness and replacing it with a pseudo-consciousness, and this so completely that the sensations of pain, taste, &c., felt by the operator, were also felt by the sensitive, and referred by him to their appropriate locality in his own body. In like man- ner the direct control of the mind of the sensitive over his body and of his body over his mind was exercised by the operator, and consciousness of pain in any part could be abolished at will. Some of these phenomena, indeed, were so curious and the mode of producing them so significant, that it certainly appeared as if the whole body was permeated by psychic substance, and that the mind was related to the outer world by psychic nerves in an equivalent sense to its material nerve connection. In these mesmeric phenomena, however, it is evident that the channel of communication between mind and mind is not usually an open one, or the body psychically transparent. Most persons are more or less obtuse to the psychic sense, and only in special cases is it freely active. And in these cases the relations of oper- ator and sensitive are personal. No second operator can exert an equal control over the sensitive. It is as if the psychic nerve, like the physical nerve, became susceptible to familiar influences, but resistant to unfamiliar ones. Of the other phenomena adduced by this society it will suffice q to refer to those of psychic communication at a distance, of which they give many seemingly well authenticated instances. In one SAAN $ 4 Pree Pie eee eae 1886. | The Relations of Mind and Matter. II of these the thought transfer passed as far as from Burmah to England. In these latter instances there was, in nearly every case, an active mental excitation in the one mind in reference to the other. They are most usual at the moment of death, the mind of the dying person appearing to be affected with a strong emotional longing to communicate with the living. In many such cases a spectral reproduction of the dying person has ap- peared to the subject of his or her thoughts, apparently in real form, but doubtless as an image impressed directly on the mind. It may be that a sudden rousing of the recollection of any dis- tant person, without its being led up to by a train of conscious thought, might, if the effect be a strong one, seem like an actual vision. An object seen is not led to by consciousness, and a mental image not led to by consciousness might easily have the force of an object seen, or of a temporary hallucination. In many of the numerous instances given, the person whose image was seen was in full life, yet in some perilous situation or other condition that would be likely to arouse sudden and intense emo- tion. And usually the recipient was the object of this emotion. There is no evidence to show that this relation did not exist in every instance, but simply that it was not always observed. As to the distances to which these impressions were frequently conveyed, or the rapidity with which they passed from mind to mind, there is nothing surprising if the hypothesis we have given be accepted. We know the rapidity with which light travels through the ether, and the electric current through solid matter, affecting objects very far removed in very minute intervals of time. We know that the influence of gravitation is felt with no apparent lapse of time through vast distances. The least varia- tion in distance and weight of one body is instantly. felt by other bodies, though they may be very distant. If there be a psychic substance it is highly probable that the same relations may exist between its separate masses. The ether may convey its vibra- tions to vast distances, as it does those of matter, and produce similar effects on distant psychic masses. If this substance is transparent to the vibrations produced by matter, matter may be similarly transparent to its vibrations and no check to their out- flow be felt. We know that an electric charge, when sent “to earth,” spreads with immense rapidity throughout the substance of the earth. It weakens as it spreads, yet may be strong enough I2 The Relations of Mind and Matter, [January, at a considerable distance to act upon a sensitive electric instru- ment. The matter of the earth may be still more transparent to psychic radiations, and permit them to spread with the utmost freedom and rapidity. Such impulses might touch without effect a multitude of minds, and yet rouse one mind to consciousness if it met there with conditions in harmony with the conditions of the vibration. A thought is an active and peculiar motor energy. | It carries with it, when emitted, the characteristics of its source. If it meets anywhere a psychic condition to which these charac- teristics are familiar, or with which they are harmonized, it might rouse a conscious response, or call up, more or less completely, the mental image of the emitting mind and person. There are other phenomena which seem to indicate the exist- ence of such a medium of psychic communication. And the in- dications are that emotion is necessary as a preliminary to distant and vigorous outflow of psychic energy, though not necessarily - so in case of contiguity. In emotion the motor conditions of the mind seem strongly exercised, as are those of matter in case of high temperature, and in both cases there seems an energetic outflow of vibrations. It is well known that a congregation ina state of emotional excitement can be swayed by an emotional speaker in a manner that utterly ignores all exercise of reason or individual intellect. The power of all great orators over an audi- ence has been largely of this emotional character, and audiences are frequently fully controlled by addresses which, read in a cool state, arouse surprise how they could have affected any person of sense. An instance of the same character is that of the sudden panic which has so often spread like wild fire through a whole army, sweeping away regiments that have not felt a bullet of the enemy. The-intense mental excitement seems to flow out in vibratory waves, affecting all minds within its influence, and arousing everywhere a similar excitement without regard to dif- ference of circumstances, History is full of instances of the same general character. And we find in every instance that it is the ignorant, or the strongly emotional, who are swayed by these influences, while the educated, the cool and the reasoning minds resist them. Several instances from the history of middle age Europe may be adduced. We might describe the epidemics of migration, as in some of the Crusades, of witch-craft, sorcery, lycanthrophy, ete., that have 1886. | The Relations of Mind and Matter. 13 from time to time broken out, and raged in spite of every effort at suppression. But we have only space for some of the more par- ticular instances. It is significant that the most remarkable of these emotional epidemics have followed terrible pestilences, famines, or other great national calamities. Thus the terrible “ Black Death ” pestilence of the fourteenth century, which threw all Europe into a condition of severe mental depression, and roused a host of superstitious fears, was followed by extraordinary * outbreaks of fanaticism. These were the Flagellation mania and the Dancing epidemic. In the one, Europe was filled with throngs of self-flogging maniacs. In the other hosts of dancing and sing- ing convulsionists everywhere appeared, seemingly possessed by a fury,and convulsively leaping until they sank down in utter ex- haustion. The Tarantula epidemic of Italy was of the same gen- eral character. Two cases related by Zimmerman may be here senica given. In one case a nun, in a very large French convent, began to mew like a cat. Soon others of the nuns imitated her, and ere long the whole of the sisterhood were diligently mewing. So strongly did the mania possess them, that it was only broken up by the stationing ofa company of soldiers near the convent, with a threat to whip any one who should indulge in the peculiar vocal exercise, Dread of the whip proveda stronger mental force than the desire to mew, and the convent returned to its former peace and quiet. In the other instance a nun in a German convent, of the fifteenth century, began to bite her companions. Soon all the nuns fell to biting one another. As the news of this spread to other convents the biting mania broke out there also, until it spread throughout Germany and Holland, and extended so far as Rome. i The emotional character of the mental operations oi a religious sisterhood probably renders them specially susceptible to such psychic influences. In all such cases a considerable degree of mental excitement seems to have attended the mania. And it has been usually confined to the lower classes, though in a case of long continuance, like that of the Flagellants, nobles and ecclesi- astics, with many other persons of honorable birth, became affect- ed. In these days of science, education, and active thought gen- erally, such extended manias have ceased to exist, though minor examples may yet be found in ignorant communities. In 14 The Relations of Mind and Matter. [ January, these instances there seems to be a general outflow of psychic energy of a peculiar kind, which acts to produce accordant states in all minds into which it flows, unless they are intellectually active enough to resist its influence. We all know how difficult it is, even in educated persons, to resist the psychic influence of a strongly emotional speaker, even though the reason may resist his arguments, and how resistance becomes lulled and conviction produced, by the pure force of “personal magnetism.” And knowing this we cannot wonder at the remarkable influence of some very irrational revivalists. The subject has here been very briefly and incompletely treat- ed. Had we space to give in full the abundant evidence that might be offered, and to detail the strict test conditions under which it was often received, the fact of a direct intercourse of mind with mind, and control of one mind by another, without the intermedium of the senses, might be shown far more clearly. And the indications strongly point to some such conclusion as that here reached, that the mental powers are based in a special psychic substance, and that masses of this substance act upon each other through the ether in methods closely similar to those in which masses of matter act on each other. © One further question of great importance here comes into play. If psychic substance begins its existence as “ bound ether,” ether condensed by the attractive force of atoms and molecules, can it exist in this condensed form separate from the atoms and ‘molecules? If these continue to exist must their ethereal atmos- pheres remain permanently bound to them? If they should in any way be destroyed, would the ethereal atmospheres resume their original condition of free ether? If we have dealt with pure hypothesis so far, it may be well to follow our hypothesis to its ultimate consequence. That bound ether is an existing fact is becoming more and a more generally admitted. Sir William Thomson, in a recent paper,’ views it as a necessary condition to the phenomena of refraction. And if it exists it seems equally necessary that the ethereal atmosphere must be affected by the motions of its nucleus and assume accordant motions. If so, the destruction of a the material nucleus might leave the condensed ether as a per- sistent atom or molecule, since it would possess the motor organ- 1 Read before the Royal Society of Edinburgh, January, 1885.

On the other hand, while the atom or molecule of matter continues intact, it would seem as if its bound ether must remain confined to it and accompany it through all its integrations and disintegrations. Absolute accordance in motions and the persistent vigor of attraction must prevent any separation of the bound ether from its nucleus. Under these conditions, therefore, there could be no separate existence of a psychic substance. But this is but one of the probable conditions of existence of this substance. Bound ether may be strongly influenced by other motor energies, which but feebly influence its material nucleus, In this respect the phenomena of the mind lead to some very interesting conclusions. If the physical basis of the mind be the bound ether of the cerebral cells and molecules, it must originally be intimately related in motion and condition to these cells and molecules, and can have no power of separate exist- ence, But the whole process of development of the mind is one that tends to break up this intimate connection. The psychic substance of the cerebrum is affected, not only by the normal cerebral motions, but by innumerable motor conditions coming from external substances, through the medium of the nervous ` system. These conditions but slightly and temporarily, so far as we can judge, affect the sluggish matter of the cerebrum, but strongly and permanently the mobile substance of the mind. The mental substratum thus becomes affected by motor condi- tions which have no fixed counterpart in the brain substance. The original close motor accordance is broken; and with it the effect of molecular attraction is weakened. Such a result would be precisely parallel to that common in chemical action, in which motor inharmony seems a steady opponent of the force of affin- ity. Affinity is most vigorous when motor harmony exists. If the motor inharmony becomes great, molecular separation takes place. A similar rule may well hold good between the cere- bral molecules and their bound ether. As the absorption of ex- ternal energies by the bound ether produces motor inharmony, the effect of the attraction is steadily weakened. The bound ether is converted into specially organized psychic substance. In such a case there might be a fresh condensation of ether around the molecules, and this, in its turn, would become the recipient of new inflowing energies. In this way a continually increasing 16 The Relations of Mind and Matter. [January, volume of psychic substance might be formed by the addition of new surface films, each becoming specially organized by sensory influences, and losing its intimate relation to cerebral matter. In such a method the bound ether of material molecules may be converted into the psychic substance of mind. And with every transfer of energy from matter to psychic substance, con- sciousness may declare itself. The conditions of mental devel- opment and mental reception of sensations, as considered in the preceding section, are in close accordance with this idea. We have not matter with two sides, or with duplicate physical and mental motor relations, as considered by Mr. Bain in his Mind and Body, but two distinct conditions of substance, originally in- timately bound together, but becoming separate as their motor conditions become inharmonious. In such a case the disintegra- tion of the brain would not carry with it the disintegration of the mental substratum. The latter has ceased to be the bound ether of the former, and the cerebral molecules could only carry with them their latest increment of bound ether without affecting that which had escaped from this condition. Nor could the energies which cause the disintegration of the brain produce the same effect upon the psychic substance. A substance through - which the most vigorous motor energies, such as those of light and heat, pass without producing any permanent disturbance of its conditions, might remain utterly unaffected by the most in- tense disrupting energy of material agencies, and survive the body as a concrete organism. In fact the close connection between brain and mind seems to depend in some measure upon the activity of the brain. This activity appears to enhance the attractive hold of the cerebral cells upon their psychic outgrowth. It is during the stage of cerebral activity that external sensations are most abundantly and intensely received. With the partial cessation of this activity which takes place during sleep, some degree of weakening of the bonds between mind and body seems to take place. During deep sickness, or at the near approach of death, the bond seems to become still weaker, and the mind, with no impairment of its activity, seems often to be partially independent of the inactive body. The complete cessation of cerebral activity, which comes with death, may utterly break the bond of connection, the mole- cules of the brain only retaining their latest increment of bound DiE s eee aed by age Ng gee eg ATR eRe yes Deen ig E a E ia Wh gg NT asia Le al ee eh es teat es ce eye OE ine ee ON Tac Sse eT ee ee Ee Ce ge Sea oe ep re eae ae ee Aa Pier fe a PP i 1886.] Notes on the Life-history of the Common Newt. 17 ether, while the organized psychic cerebrum becomes a free organism, Whether with it is freed a closely related psychic organism, the outcome of the whole body development, and reproducing every detail of the body, is a question of secondary concern. It is sufficient for our present purpose to show the con- ceivable separate existence of a psychic cerebrum, possessing the definite organization of the material cerebrum, and in addition all the thought conditions of the developed mind. If the human body, as the highest outcome of its organization of energy in matter, is capable of producing such a self-centered and self-existent psychic organism, a like power, though in a lower degree, must exist in lower organic beings, and possibly in inorganic compounds. Every concrete mass which received external energies, without being molded by them, might have its bound ether molded by these energies and thus converted into psychic substance, capable of self existence when definitely sep- arated from its nucleus. All matter may thus act as a laboratory for the elimination of psychic substance from bound ether. The freed mental organism might find an accordant sphere of exist- ence thus prepared for it, and as thoroughly adapted to its pow- ers and needs as the material earth is to ours. Nor could we become sensible of the existence of substance in this condition, its complete transparency to radiations of light and heat render- ing it imperceptible to our senses and our instruments. Such may be offered as a speculative conception of the possibility of the existence of the mind after the dissolution of the body, ina sphere of substance suitable to its needs and powers. It is a con- ception towards which many partial steps have been made, but this may be offered as the first definite hypothesis of the devel- opment and conditions of the mind, based upon the conclusions. of modern science. SOME NOTES ON THE LIFE-HISTORY OF THE COMMON NEWT. BY COL. NICOLAS PIKE. To little reptile, our common newt or spotted eft, Diemycty- lus miniatus viridescens (Raf.) Cope, is numerous on Long Island from Brooklyn to Greenport, and is equally well known all over the Eastern States. It may be caught. from March to December, as it bears a very low temperature, and I once saw it v 2 : 18 Notes on the Life-history of the Common Newt. |January, swimming under the ice in a pond near Fort Hamilton. It is gregarious, bears confinement well, and I have often kept it for over a year in my aquarium. Its food is very varied; it will take aquatic and other insects, small tadpoles, worms, especially earthworms, and it will eat small pieces of raw beef and fish when hungry. Though a harm- less little reptile, it will quarrel occasionally with its companions about food. I have seen one seize a worm twice its own length and try to gulp it down holding it with the hands; a second would snatch up the other end and begin swallowing it till the two met. Then such a pulling and wriggling ensued, till the strongest or most persistent succeeded in making the other disgorge its meal. Sometimes it would take nearly a day before the worm vanished, the first part having to be digested before the last could be swallowed. In confinement they.should have only the smallest worms, as the large ones disagree with them, and I have often had them die after one of these gorging meals. They are very fond of the small fresh-water bivalves so abundant in most of the ponds they frequent. Many are swallowed whole; one I dissected had four —shells and all—in its stomach. When caught the little harmless creatures do not try to escape but hang limp in the fingers. They are, however, as cunning as all the rest of their race. I placed one on my table to examine it, when it crawled under a sheet of paper and crouched down as if asleep. I was called away for a few minutes, and on my return 4 found my little friend had absconded. Now it had not attempted _ to move for over an hour in my presence, but was evidently at -once conscious of my absence. It was sometime before I found it — on the opposite side of the room, it was so nearly the color of the — carpet. It never does to trust to the apparent helplessness of any animal, for what it lacks in outward means of defense it is sure to make up in cunning. I accidentally found out one of this animal’s most deadly ene- a mies. I once brought home a lot of the viridescens in a box of leaves in which I had thrown some wire-worms, thinking they might serve as food, they were so abundant around the pond. The next morning I found my poor little prisoners had all been — 1Sometimes they emit a faint cry, but this is generally in the breeding season.

One had coiled so tightly round its victim it was paralyzed and died directly I removed it. Though so abundant, yet large numbers when young are devoured by the strong larvæ of the Amdlystoma punctatum ; the robust frog tad- poles also mercilessly nip off their gills and tails, and they soon die. These facts I have often witnessed in my aquarium. Everyone knows these pretty olive-backed newts, yellow underneath, the whole body and tail spotted black, and on the sides a row of flame-colored spots encircled black, but every- one does not know, and perhaps never saw the change that takes place on the approach of spring, when the males assume their brightest dress preparatory to courtship. Over the back and tail waves a graceful spotted crest, the color underneath changes to orange, and the inner side of the legs is deeply barred jet black—all of which last during the breeding season and then the crest is absorbed, the black bars and bright color fade out till the next love time of the year calls them forth. I believe this animal is incapable of reproduction under four years of age, for its growth is very slow even in its natural state. When the love-making commences there is a busy time amongst the denizens of the ponds. The males dart about, gyrating round their chosen mates, heading them off in their endeavors to escape, and when they have at last won the victory they seize the females round the lumbar region and remain thus often for hours. The milt and ova pass simultaneously, and the operation takes some time, but it is generally accomplished under cover of darkness. The older females often deposit 150 to 300 eggs at a time, which they attach to twigs in the water or long grass. The eggs are very small at first but rapidly swell. Younger females only from twenty to fifty eggs in a small group. I am not aware of any one having published any account of the hatching of the eggs of D. viridescens except Professor A. E. Verrill, who, in the Amer. NaTuRALIST for 1870, wrote as follows : “ The eggs of the common water newt were observed by Mr. S. J. Smith and myself at Norway, Maine, in ’63 and ’64, attached in round masses, two or three inches in diameter, resembling frogs’ eggs, on stems of water plants in ditches in a meadow. The eggs were found May 5th, and reared by Mr. Smith, hatched May 17th, and by October 1st were one and a half inches long. They 20 Notes on the Life-history of the Common Newt. [January, had stout bodies and broad heads, and still retained their exter- nal gills, though they had partially acquired the colors of the adult. The experiment was then discontinued but the specimens all preserved.” This only came under my notice in October, ’84, when I was delighted to find Professor Verrill’s statement verified my own experience, which I will now relate: On the 6th April, ’84, a quiet cool morning, whilst sweeping my net in a pond at Jamaica ridge, I detached some bunches of ova from several dead branches that lay in the water. They varied in size from two and a half to six inches in diameter, con- taining from 25 to 150 eggs each, all enclosed in a glairy mass. The eggs were brown above, pale beneath, each in a greenish double envelope, but so transparent that the development was distinctly visible. GAGES nS This is a most perfect arrangement for the protection of the _ ova; a space lies between the envelopes and each can be sepa- rated in its own globe of glaire from the rest. These coverings are tough and not easily injured, and so firmly attached to the branch I had difficulty in loosening the whole without breaking it up. It would take a very strong wind or current to dislodge these carefully protected embryos. They were all deposited on the south side of the pond where the sun shone in between the trees, about six or eight inches _ below the surface, in very clear water. I brought them home in a pail of water and placed them in an aquarium. I prepared for _ them with aquatic plants and débris from the pond. I thought I had secured the spawn of the A. punctatum, not thinking of — | Diemyctylus, which is mostly accredited with depositing one or two eggs separately in a folded leaf. From the appearance of the | 2 ova some must have been laid the preceding night, while others showed a curious mass of small granulations. In a few days a sort of break up of some of the ova took place, if I may so express it. The embryo assumed a fish-like appearance with a blunt head, curled up tail and a thick solid — body. During the next fourteen days the brown body enlarged, head was very dark, outline of eyes visible, snout broad and j thick and if shaken the little creature displayed considerable irri- tation by a twitching of the tail. By the 2oth the body was elongated and curved, the flattened tail showing a fin, the verte- — 1886.] Notes on the Life-history of the Common Newt. 21 bral striz and branchiz with the minute claspers all were visible with a good glass. The glairy coverings enlarged with the crea- ture’s needs, and by the 28th some had emerged and commenced life on their own account. On the goth May the film disappeared from the eyes, the gills were free, and what seemed to be thin white threads were really the. first appearance of the anterior legs, but only by the aid of a powerful glass could the two little claw-like fingers be seen. A dark stripe showed from nostril to eyes and another on the head, and the whole body was covered with fine dottings. It is very difficult to know what is the food of these mites, at this stage only half an inch long, It can only be the minute monads and confervacious spores in the water. The glairy en- velopes remained long without decomposition, intact but for the cleft by which its occupant emerged. I am half inclined to think the young still feed on them, for they hang round them con- stantly; I know frog and toad tadpoles will feed greedily on these empty shells. The little newts would remain motionless for a long time as if dead, but if disturbed would rush madly round. The whole of the ova did not hatch till the middle of May, so the first out must have been laid in March. By the 15th there was little doubt in my mind that I had at last solved the problem of the spawning of the Diemyctylus. The reddish gills were well © fringed, the eyes prominent, the front legs transparent and white fingers free, the abdomen shewing the viscera, and the body dotted all over. A dark stripe from snout to eyes is, I find, never absent in the larva of this species. On the 25th I procured a quantity of Lemna or duckweed for my aquarium, and it spread all over the surface of the water. My little pets delighted in it,and when the sun shone they would _ crowd under it in every position, seeming to hang on to the slen- der roots! They certainly throve in their leafy home, and flour. ished So well that in a month, on the 25th of June, they were an inch long, very active, brownish-gray in color, with a series of whitish markings where the spots were to appear later. The - abdomen alone was spotless. Two fingers and two knobs showed in front, and the hind legs were out but the feet only slightly ‘Possibly the Lemna contained minute spores, or ova of insects, which Served them as fresh food. é \ 22 Notes on the Life-history of the Common Newt, |January, developed. The young begin to molt in confinement about the second month; later on, with every change, the spots which are only blurred white markings at first, assume a more definite shape. The adults change their skin frequently when they have abundant food, which has the same effect on the Urodela as on the ophidians. Thus far all went well, but then began the great trouble always experienced at this stage in rearing the Urodela, much greater than that of the Anura. The latter will feed greedily on decom- posed animal matter that the former seem to care little for, in confinement at least. I tried every kind of aquatic plant and small insect I could get from the ponds, but uselessly, many died and the rest were thin as shadows but active as ever. A few sur- vived till August and well proved their identity, when I put the last but one in spirits to save its life! The last I kept alive till nearly the end of the month by feeding it on little red mites that swarm in the ponds at that season, but even it succumbed, and it was still only one inch long when it followed its mates, never having grown since June. I preserved a series of specimens from the spawn upwards, and I hunted the ponds so persistently that I | was able to supplement my own deficiencies by larve from them in every stage, so that now it is complete in my cabinet from spawn to a fine adult five inches long. To show the difference in rearing these animals in confinement and in their natural state, I will mention that on June 14th I took some larvz from the same pond over two inches in length and quite fat. Doubtless the great increase of size over mine was due to abundance of suitable food, fresh air and abundant room to swim about in. I have had ample proof that the breeding season extends even to May, from the very small larve I have taken even in July. Some young taken in September were a dark olive, the tail : nearly black and feet dark ; those of October showed a little dot- ting on the chin; those of November had the gills absorbed, were about two and a half inches long, and were sparsely dotted — underneath, but fhe side spots still white. I do not think the flame color always comes in till the second year, and the buff — color of the abdomen shews about the same time. As the ani- — mal nears the period when the gills completely disappear, its — body diminishes in size, and I have taken some in the second : 2 ee 1886.] Notes on the Life-history of the Common Newt. 23 year on land barely two inches, tail included. The atrophy of- the branchiz begins at the extremities and goes on very gradually till the fimbriz are absorbed, when the rest roll up and leave two rounded tubercles that I have still found in specimens taken in December just before hibernation.’ As the gills are absorbed the form of the head changes. During their growth it widens con- siderably in front of them, but on absorption the neck becomes narrow, and between the eyes it is broader. The fin, round back and tail vanishes at the same time. , Both sexes leave the water after the mating is over for a time, and hide, without feeding, under stones and tussocks. The young of the second year sometimes leave the water for months to- gether and secrete themselves in damp places. When droughts occur and the ponds dry up I have often dug them out, all hud- dled together, more than a foot below the surface, and where the clayey-ground has become so parched that they are unable to burrow they are often seen several together, dead and dried up. This season, 1884, an exceptionally mild one, I took, ona bright warm day early in December, quite a number of large viridescens, both male and female, very active although there was a thin coat- ing of ice on the pond. The former had the legs already barred and the tails finned, while the latter were large and fat. I dis- sected a female and found her full of good-sized ova. Diemyctylus mineatus (Raf.) Cope (Eastern water newt).—This little animal, formerly supposed to be distinct from the last de- scribed, and mentioned in the latest bulletin of the Smithsonian Institution, is now generally acknowledged to be only a color variety of the D. viridescens. Dr. Hallowell was the first to express his belief that the so-called distinct species were the same. Professor Cope’ says, “the nominal D. miniatus is a state of D. viridescens,” and that he has had it change to the latter in confinement. Mr. Howard A. Kelly, in an article in the Am. NATURALIST, states, “he brought home a number of D. miniatus (Raf.) or little red lizard or red eft, and after keeping them in a dark box filled l These animals do not, I believe, really hibernate in the usual acceptation of “a8 : term, thats, they do not often become dormant.

Professor Cope has studied the Urodela perhaps as much and as carefully as any one in this cquntry, and is therefore an undoubted authority on the subject,” —- 24 Notes on the Life-history of the Common Newt. (January, with saturated moss, they changed their color from a bright ver- milion to the olive state characteristic of the D. viridescens,” and he kept them all winter. I have gradually come to the conclusion that the two are iden- tical. Some years ago I captured quite a number of red ones in the Catskill mountains, brought them home and kept them ina box with other salamanders, where they could resort to water if they chose. For some days they remained hiding under the wet moss and stones, but finally crept out at night and went into the water. I gave them insects and worms, which they readily devoured. In about three months they lost their bright red, and in less than a year they were of the usual olive of the viri- descens. — Another fact still more decidedly bearing on the case, is, that some two year old olive-colored viridescens taken from the ponds and put in earth and dead, wet leaves in a tub in my garden with- out water, in a month or so began to lose their green tint and assume a dingy brownish hue. It is well known that the Diemyctylus often stays away from water for months at a time, but roams round at night in the damp earth and grass in wet weather. The food these animals take plays also a very important part in their coloration and growth, just as we see in the whole animal kingdom. In the ponds the viridescens is generally a dull olive, almost the color of the green slime and plants covering them, in which they hide almost unseen. On land, where they are always in the day time, either under stones or dead wood or in the earth they have burrowed in, they assume more the color of these ob- jects to hide from whatever enemies they may have in their new habitat. Then as to food; in the water they have abundance of succu- lent nutriment — mollusks, tadpoles, ova of reptiles and fish, _ aquatic insects and plenty of confervaceous plants on which they — and their prey alike feed, and which doubtless assists in their col- oration. Now as soon as they leave the water their food changes _ at once to spiders, insects, earthworms, &c., so totally different — from the prey of the ponds, and it is most probable this is the first cause in the change of color in the little Diemyctylus. Locality has also considerable to do with the tints of the skin — in these animals, as we see so prominently in snakes, especially — eee tear we 1886.] Relation of Pectoral Muscles of Birds to Power of Flight. 25 in the genus Eutznia, where difference of locality has had such an effect on the coloration as to give rise to several species being made out of the common garter snake. I have procured these newts from many places in New York and New Jersey States and different parts of Long Island, of every shade of red up to very bright scarlet, yet within a radius of many miles from Brooklyn, where the wridescens and its vari- ety are both plentiful, I never find the latter other than a reddish- brown, varying from light to very dark. Sometimes late in December I find little brown ones with flame-colored spots, in the ponds. These are so greatly attenuated it is possible they have returned to the water in search of food, lacking on land, at so late a period when all animal life which would be available for them disappears from the surface. A+ THE RELATION OF THE PECTORAL MUSCLES OF BIRDS TO THE POWER OF FLIGHT. BY CHARLES L. EDWARDS. o all the modes of animal locomotion flight is the most rapid, the most graceful, the most fascinating. With one important exception this power separates the bird from the other verte- brates and gives it preëminence in motion. Its whole structure— the conical form of the body offering so little resistance to the air, the hollow bones, the air-sacs and the weaving together of the smallest barbules to form the close web of the wing—all denote that in the air, in flight, is the bird’s life. - While in a very general way much has been observed with regard to the variation in the power of flight of species differing quite widely from each other, yet there are still some unsolved problems connected with the highest form of motion. Before attempting the solution of any special problem there are certain mechanical elements of flight with which we must become familiar. A body much heavier than air is to be propelled with great speed through the air. The resistances are the force of gravity and the air itself. The perpendicular action of the. broadly expanded wings op- poses as much as possible the force of gravity, while the narrow 26 The Relation of the Pectoral Muscles of January, wing-line and the cleaving form of the conical body reduce as much as possible the resistance of the air in front. The cause of motion is the action of the wings upon the highly elastic air producing by reaction forward movement of the body. The source of this action is in the pectoral muscles, Its instruments are the wings. Wonderfully indeed are the wings adapted to their purpose. Of extreme lightness and of great rigidity and strength, their weight is but a slight hindrance and their leverage a vast advantage in producing motion. Concave beneath and convex above, with underlapping feathers, to the one side is presented a grasping surface almost impervious to air, and to the other a lattice-work structure through which air easily rushes, So in the depression of the wing all possible advantage is gained from the elastic resistance of the air, and in its elevation the least amount of force is lost. The muscles which furnish the propelling force to the wings are those of the breast, the pectoralis major and the pectoralis minor. The pectoralis major is a large, triangular muscle form- ing the principal part of the bulk of the breast. It arises from the ribs, from the outer portion of the ventral surface of the sternum, from the side of the keel of the sternum, from the fur- culum and the membrane connecting the furculum with the sternum and the coracoid. The fibers converge, the outer turn- ing under the inner and inserted by a tendon on the greater tuberosity of the humerus. In action this muscle depresses the wing and thus furnishes the great motive power of flight. The pectoralis minor is much smaller than the preceding, and beneath it; arising from the middle portion of the sternum and _ the membrane attaching the furculum to the sternum and the coracoid. Its fibers converging terminate in a tendon which, after passing through the end of the coracoid, is inserted on the inner side of the greater tuberosity of the humerus. This muscle, to- gether with the resisting force of the air, elevates the wing after it has been depressed. From the structure of the wing it is apparent that the work of this muscle is relatively small except, perhaps, in “ sailing,” as seen in the flight of swallows, where the wings must be held — tense and at a constant angle by this muscle. It would clearly appear, when we consider the law of muscular development, that __ in those species which fly most of these muscles would be rela- RoE ey et 1886. } Birds to the Power of Flight. 27 tively larger than in those of less power of flight. Conversely, other things being constant, those birds in which the pectoral muscles form a larger percentage of the weight of the body, would have a greater power of flight. This being true the question naturally rises: What is the varia- tion in the development of the pectoral muscles for the different species of birds, and is this variation by natural families or by individual species ? In the solution of our problem the shape of the wing plays an important part. The long, narrow, sharp-pointed wing is most advantageous to continued flight, and the shorter, rounded, less- compact form is least so. Between these two extremes there is an indefinite shading of the one form into the other, with more or less resulting advantage as the case may be. The pectoral muscles may be relatively large, yet if the wing be of impeding form, so that considerable force is lost in over- coming the consequent disadvantage, the resulting power of flight is much lessened. In this paper I have taken the weight of the whole body as a constant basis and found the percentage by weight of the pec- toral muscles in the body. The data are derived from the dissec- tion of 119 birds, having in all cases possible taken an average for each species from three individuals. There are represented seven orders, twenty-five families and fifty-three species. It will be seen that variation is not by natural families but by individual species. This is explained by the fact that though certain species may have structures so allied as to join them together in a family, yet because of their distinct habits of life they may differ considerably in their power of flight.

"2°. VY GEOLOGICAL EXTINCTION AND SOME OF ITS APPARENT CAUSES BY A. S. PACKARD. N his Origin of Species, Darwin says: “ The extinction of species has been involved in the most gratuitous mystery. Some authors have even supposed that, as the individual has a definite length of life, so have species a definite duration. No one can have marveled more than I have done at the extinction of spe- » cies.” Finally, he remarks, “ Thus, as it seems to me, the man- ner in which single species and whole groups of species become extinct accords wells with the theory of natural selection. We need not marvel at extinction; if we must marvel, let it be at our Own presumption in imagining fora moment that we understand the many complex contingencies, on which the existence of each species depends. If we forget, for an instant, that each species tends to increase inordinately, and that some check is always in action, yet seldom perceived by us, the whole economy of nature will be utterly obscured. Whenever we can precisely say why this species is more abundant in individuals than that; why this species and not another can be naturalized ina given country ; then, and not till then, we may justly feel surprised why we cannot account for the extinction of any particular species or any group of species.” The fact of extinction is indeed not less marvelous than that f 30 Geological Extinction and | [ January, of evolution, and one cannot in these days feel satisfied that the solution of the problem lies in the theory of natural selection, which accounts for the preservation of species rather than their origin or extinction. Mr. Darwin having been the means of bringing many naturalists to believe in the theory of descent, they are not to lie supinely on their backs, resting securely on the dogma of natural selection and cease from all attempts to inves- tigate the cause of evolution, to cease building a foundation for the working of natural selection. On the contrary the search for the causes of the transformation of species will be carried on with more energy, thoroughness and success. The clews which we already have discovered will be followed up, and finally we shall, by means of observation in the field and experiment in the labor- atory, wrest from nature the secrets of life and its origin, and of the phenomena of death and extinction, not only of species but of orders. Extinction may be both slow and rapid, the causes of each be- ing primarily dependent on slow or rapid changes in the environ- ment. The object of this article is to endeavor to show that the extinction of species is intimately connected with geological changes. It is a meagre sketch or outline of the more salient facts and laws which appear to us to immediately bear upon this intricate and difficult subject. _ In Paleozoic times the climate of the globe was far more uni- — form than now. The continents of the present day were then of — much less extent, in fact archipelagoes rather than continents; the land-surfaces were of moderate height, and mountain ranges _ smaller and lower. While the land masses or embryo continents — of the eastern and western hemispheres were more or less inde- — pendent centers of evolutionary creation, there was on the whole — a great uniformity of plant and animal life. Species were per 2 more cosmopolitan than now. When at the end of the Coal period the process of ~ontingel a making and mountain-building became greatly accelerated, result- ing in that stupendous crisis in American geological history, the _ upheaval of the Appalachian mountain system, there must have been some degree of differentiation or setting aside of portions of : 1 the then continent into distinct areas or basins bounded by moun- 4 tains, inland seas and rivers, and some slight subdivision into local faunas. We know that there was a distinct coal basin, or : : a eS all = ees eh ess 1886. ] some of its Apparent Causes. 31 series of them, for example in Arctic America, another in North- eastern United States, and in the Central States of the Upper Mis- sissippi valley. Other crises, extending over comparatively brief periods of geological time, however long when measured by centuries, were the elevation of the Rocky mountains, of the Wasatch, the Uin- tah ranges, the Sierra Nevada and Cascade ranges; and, mean- while, the union of the Atlantic moiety and the Pacific moiety of our continent into a continuous land-mass. These periods of ac- tivity, signalized by extensive volcanic outpourings and great changes in the relative distribution of land and sea, must have been, as palzontology shows, periods of rapid extinction as well as of reparation or recreation. Progress in continent-making was accompanied by progress and an onward sweep in the tide of life, not only in animals with jointed bodies and limbs, but more espe- cially in those with back bones and brains to correspond with their vertebrate rank. Until the end of the Tertiary period the earth’s climate was still nearly uniform. There was through the Miocene a general, in- deed most remarkable resemblance between the flora of Europe and the United States, with that of Greenland and Spitzbergen, or the regions now lying in the frigid zone ; this flora being in some respects like that of Louisiana. It was not until the Glacial epoch that the earth’s climate be- came differentiated into tropical and frigid and temperate zones: That great geological crisis, whether due to astronomical or geo- logical causes, or both combined, by which over enormous tracts of land in Northern and Central Europe, and Northeastern Amer- ica a frigid climate, with continental glaciers, was spread—that crisis produced results on the life of the glaciated region which we can easily appreciate. The extinction of life over the stated areas became widespread. The incoming of the Ice age also must have induced extensive migrations to the southward. As the glaciers melted, and the climate ameliorated, fresh migrations from the south set in, and thus in the early Quaternary period, when species were exterminated on a vast scale by causes readily appreciable, we have set before us, in a language which every one can translate, some of the geological causes of extinction, modi- fication and consequent evolution of new forms. We will begin, then, with a reference to the changes in the life 32 Geological Extinction and [January, of the northern and southern hemispheres due to the glacial period. They are so familiar to the general reader that they need not detain us long. By the end of the Tertiary period the northern regions, includ- ing the land around the north pole, viz: Spitzbergen, Novaya- Zemlya, Siberia, Greenland, together with Northern Europe and Northeastern America, must have abounded in life. Forests of trees, deciduous, evergreen and palmaceous, in their general ap- pearance resembling those of Louisiana, spread like a mantle over the land, bordering the vast Tertiary lakes and sheltering herds of herbivorous mammals, such as deer, oxen, mammoths» which were attended by packs of dogs, or by solitary secretive cats prowling through the forest glades, waging war on the weak and defenceless or scattered ruminants. This rich assemblage of mammalian life, with countless species of insects, and other invertebrate organisms, land, fresh-water and marine, was swept away. A large proportion died outright, perhaps a larger proportion migrated southward; a very small per centage survived. The mammoth and mastodon lived on, adapted themselves to the great change of climate, but just as the ice had passed away and the climate had ameliorated, and when the condition of life seemed more favorable, they suc- cumbed, The Arcticgbear, fox, lemming and hare, with the white ptarmigan and snowy owl, by adaptation to a snow-clad land sur- vived, so to speak, the change, or rather, they are the descendants — ) of species so plastic that they became modified, and adapted to añn Arctic life. Even man, who appeared in the old world before of about the time of the incoming of the ice, not only followed the retreat of the glaciers, but adopted a strange sort of existence ina mean annual temperature of less than 32° F. Wherever the Eskimo lived he found the walrus and seal, the modified relatives of the sea lions and sea elephants of _ other parts of the world. The profusion of Tertiary insect life was succeeded by a scanty assemblage of Arctic butterflies, — ls - Lets | 41 a -5'V"-.

It is sufficiently manifest that the circumpolar flora and fauna are the dwarfed, or otherwise modified descend- fe 1886. | some of its Apparent Causes. 33 ants of the Pliocene-Tertiary life of the same regions. Again, peculiarities inthe distribution of plants and animals in North America and Northern Eurasia indicate strongly that there was an extensive migration southward down the Atlantic and Pacific borders of the continents as the glacial cold crept over the once populous circumpolar regions. A second series of causes of extinction arose from the eleva- tion or depression of extensive regions of the earth. The par- oxysmal, elevatory process in the formation of the Cordillera of North, and particularly South America, involved corresponding more or less rapid changes in the flora and fauna of the Pacific Coast regions of those continents. In South America, particu- larly, during the Quaternary period, though there was no glacial period north of Patagonia, the extinction of life was widespread and marked. As observed by Darwin and Alexander Agassiz, within historic periods there have been paroxysmal upheavals over thousands of square miles, if not over the whole extent of the Western Andean plateau. For example, in 1822, after an earthquake, the coast line of Patagonia and Chili was suddenly elevated from two to seven feet above the level of the ocean. In 1835 Darwin, while at Valdivia — on the coast of Chili, experienced the earthquake which devasta- ted Conception, and he says his “compassion for the inhabitants was almost instantly banished, by the surprise in seeing a state of things produced in a moment of time, which one was accustomed to attribute to a succession of ages. In a single day, Feb. 2oth, this earthquake shook the coast of South America over an area 600,000 square miles, and the whole coast line of Chili and Pat- — agonia was elevated from two to ten feet above the sea level.” Darwin in his Voyage of a Naturalist remarks: “ At the island of S. Maria (about thirty miles distant), the elevation was greater ; on one part, Captain Fitz Roy found beds of putrid mussel-shells ` still adhering to the rocks, ten feet above high-water mark; the inhabitants had formerly dived at low-water spring-tides for these shells. The*elevation of this province is particularly interesting from its having been the theatre of several other violent earth- quakes, and from the vast numbers of sea-shells scattered over the land, up to a height of certainly 600 and, I believe, of 1000 feet. At Valparaiso, as I have remarked, similar shells are found at the VOL. XX.— NO. I, 3 34 Geological Extinction and [January, height of 1300 feet; it is hardly possible to doubt that this great elevation has been effected by successive small uprisings, such as that which accompanied or caused the earthquake of this year, and likewise by an insensibly slow rise, which is certainly in pro- gress on some parts of this coast.” Darwin adds: “Two years and three-quarters afterwards, Valdivia and Chiloe were again shaken, more violently than on the 2oth [Feb. 20, 1835], and an island in the Chonos archipelago was permanently elevated more than eight feet.” As observed by Mr. A. Agassiz, there are sea corals of species still living in the Pacific ocean adjacent, attached to the surface of interstices in the rocks at Tilibiche, Peru, at a point about 2900 feet above'the level of the sea. This locality is situated on a ridge parallel to the coast, there being a pampa or basin be- tween this ridge and. the coast range. This basin was probably the bottom of an internal sea which afterwards became a salt lake, and was eventually drained into the Pacific by the breaking through of the mountain barriers. The extensive saline ba- sins on the western slope of the Andes, at an elevation of over 7000 feet, may have been former ocean bottoms. In his Andes and the Amazon, Orton says: “ President Loomis of Lewisburg University, Pa., informs the writer that in 1853, after nearly a day’s ride from Iquique, he came to a former sea-beach. It fur- nished abundant specimens of Patellz and other shells, still per- fect, and identical with others that I had that morning obtained at , Iquique with the living animal inhabiting them. This beach is _ elevated 2500 feet above the Pacific.” (p. 116.) Also, the pres- E ence of a species of Amphipod Crustacean belonging to “a truly marine family,” dredged by M. Agassiz in Lake Titicaca at a _ depth of sixty-six fathoms, indicates that this lake may be a rem ~ nant of the Pacific ocean ; though it now stands at an elevation of 12,500 feet above the sea. These facts tend to prove that the Andean plateau during the Quaternary period was paroxysmally elevated into the air some _ 12,000 feet. Let us now look at the possible results of such an enormous upheaval on the plants and animals of this region. Be- 4 fore and at the time this movement began, when the land was ~ 12,000 feet lower than now, the Atlantic trade winds which now cross Brazil, impinge upon the Andes and drop their moisture on the eastern slopes alone, then favored as well the western slopes — s Fa n Sap eae E EO E Sees 1886. } some of its Apparent Causes. 35 and Pacific coast. The tropical flora and fauna now confined to the neighborhood of Guyaquil on the coast of Peru then probably spread over Bolivia, Ecuador, Peru and Chili to Patagonia. The tropical belt in Peru ends with the chinchona forests of Loja, which is 6768 feet above the Pacific ocean. The sugar cane grows in Baños which is about 6500 feet high. At Riobamba, with an elevation of 9200 feet, the climate and vegetation are temperate ; here occur bones of the mastodon, horse, deer and Ilama—animals which may have lived in a temperate climate. But was not their extinction, and that of the colossal sloths, armadillos, and other animals of the pampas largely due to a change of climate result- ing from the elevation of the Andean plateau ? As the land gradually rose, the atmosphere would become more rarified and insupportable to tropical life ; the animals and plants would either seek lower levels or undergo extinction, or in certain cases become modified into species suited to a temperate climate. As the plateau rose still higher, the air would become too cold and rarified for even the mastodon and horse. Gradually an alpine zone became established, and finally the higher peaks of the Andes, at an elevation of 15,000 feet, became mantled with perennial snow, and on the eastern flanks of Chimborazo, which intercepts the moisture of the Atlantic trades, glaciers established themselves. We thus see how, within Quaternary times, temperate and alpine zones became established over the vast Andean plateau, originally, perhaps at the end of the Pliocene, a plateau of the third order, clothed with vast forests like those of Brazil and Venezuela. In Patagonia, likewise, the elevation of the Cordillera, and the change of level of the low lands of the eastern coast, now well- known to have happened, are they not sufficient to account for the extinction of the fauna of the pampas ? The same phenomena obtained in Western North America. Throughout the Tertiary period there was in the northern portion — of the plateau region a secular rise of land, if not at times parox- ~ ysmal, resulting in the drainage of the plateau into the Pacific and the formation of vast inland seas and estuaries which eventually became fresh-water lakes. During the Laramie epoch the Rocky mountain plateau be- came dry land, and the elevation and drainage went on during the Eocene. The Gulf of Mexico was much larger in the Eocene epoch than now; afterwards the coast of Texas rose from 300 36 Geological Extinction and (January, to 700 feet, while farther north, in Colorado and Wyoming, the Rocky mountain plateau rose from 4000 to points 10,000 feet above the ocean. . The plains east of the Rocky mountains are underlaid by beds deposited by vast inland, fresh-water lakes. In Texas these beds dip under the Gulf of Mexico, but at the base of the Rocky moun- tains in Colorado they are 7000 feet above the sea. They have been tilted up. Gen. Warren and Mr. King have shown that after the Pliocene epoch such a tilting took place. These lakes dried up, and the marvelously abundant mammalian life which thronged about their shores became extinct as the Quaternary period opened. May not the extinction of life so widespread throughout the West, particularly at the end of the Eocene, the Miocene and the Plio- cene, have been mainly due to the great changes in the physical geography of that vast region? We see also whya semi-tropical climate and flora and fauna continued to exist around the Gulf of Mexico, but ceased to live on the elevated Rocky Mountain pla- teau, as well as the Sierra Nevada and Cascade plateaus. The whole western portion of the continent was carried up bodily, the lakes drained off by the Missouri, Columbia and Colorado rivers and the air at such an elevation becoming rarified, dry and cooler, the tropical life became either extinct or migrated southward to warmer and lower regions. Towards the end of the Pliocene mul- _ titudes of llamas, droves of horses, mylodons, elephants and mas- — todons, with lions, cats and dogs, flourished in Oregon, Montana, Utah, Wyoming, Colorado and New Mexico; changes of level 2 and consequently of climate were perhaps the main factors con- cerned in their demise. There were throughout the Tertiary most widespread and all : pervading geological changes, culminating in the upheaval of the two great mountain chains of the West. Horizontal Cretaceous strata lie on the Rocky mountains at an elevation of 10,coo feet, the sign and proof of an extensive upheaval. We know that the T movement in South America, while gradual for the continent, was more or less locally paroxysmal. Was it not the case also in _ North America ? _ By the end of the Pliocene, North America assumed its present — continen.al proportions. The Rocky mountains and Sierras shot — their peaks into the sky to elevations of 10,000 and 1 5,000 feet above the Pacific. These great walls shut off the moist trade winds © “es tars aie ye es Sree eee 1886.] some of its Apparent Causes. 37 from the Pacific, a period of dessication set in throughout the great basin between the Rocky mountains and Sierra Nevada, and exten- sive rainless districts resulted, But even then there were alter- nate wet and dry cycles throughout the early Quaternary. Great Salt Lake, from being a vast body of fresh water, became a shal- low brine pool; the sources of the Colorado, Columbia and their tributaries likewise partially dried up. Finally, the Glacial epoch came in, the glaciers invaded North- eastern America; these on the one hand, and the great elevation of the western plateau, seem to have been the causes which re- moved the Pliocene fauna; which removal was, geologically speak- ing, comparatively sudden. Either at the end of the Pliocene or beginning of the Quater- nary, as seen by the bones in the Port Kennedy cavern described by Professor Cope, there was a singular mixture of what we now regard as tropical and temperate forms living so far north as Penn- sylvania; with the tapir, peccary, Mylodon, Megalonyx, Castor- oides and sabre-toothed tiger, were apparently associated the deer, bison, horse, porcupine, raccoon, dog, weasel and smaller mam- mals. The fauna was in part extinguished by the glacial cold, Port Kennedy being situated a little south of the edge of the great glacier. The result of a change of climate was a change in the nature of the forests ; the tapir and peccary were forced to migrate south- ward ; the colossal sloth and sabre-tooth tiger died outright; the Castoroides, horse and mastodon lingered through the Glacial epoch, their remains being found at the bottom of swamps, but above the glacial and river drift; while the deer, bison, raccoon, dog or wolf, and other forms survived with unimpaired vigor and became adapted to a lower climate, forming the typical members of the north temperate fauna of America. | Farther south, in the river gravels and caves of the Middle and Southern States, are found the bones of the great sloths, Megathe- rium, Megalonynx and Mylodon, the American lion and bear ; these were possibly swept out of existence by the cooler winters of the Mississippi valley, which was free from ice, but probably had from their proximity to the great glaciers a lower climate than in Pliocene times. Professor Cope remarks: “ Since the Eocene, the mammalian fauna of the northern hemisphere has diminished in number of Boo Geological Extinction and [ January, species and genera. The Eocene fauna was richer than the Mio- cene, the Miocene than the Pliocene, and the Pliocene than the modern fauna.” There is certainly a significant parallelism be- tween the widespread changes in the physical geography of North America, the differentiation of climates and of faunal areas, and the increasing extinction of life. | The West Indies meanwhile were the scene of notable changes in the distribution of land and sea. From being much larger, and in some cases connected perhaps with South America, they be- came submerged, Cope has described the fossil remains found ina cave on the Island of Anguilla. Out of twelve species of mam- mals, seven are extinct and several were chinchillas of large size. About the shores of the Mediterranean there were remarkable changes in the relations of land and sea. The species of dwarf and other elephants whose bones have been discovered on the Is- land of Malta, show that within recent times that island must have been connected with the main African continent. In the old world, simultaneously with the mountain-building of 4 America, the Alps during the later Pliocene attained their present proportions ; the Himalayas rose to their present heights; the continents of Asia, with Europe, and of Africa assumed their pres- ent outlines. The extent and nature of the changes which took place late in i the Pliocene in the physical geography of the globe were without __ doubt much greater than at any previous time in the history of our planet. While the present coast lines were being established volcanic agencies were widespread and powerful, and over what were then regions of intense volcanic activity are to be now seen but the dyingsembers of subterranean fires. The long, quiet preparatory eons of the Mesozoic and early Tertiary, were succeeded by a crisis in geological history, just as _ the comparative quiet of the Paleozoic age terminated in the — widespread disturbances which took place at the end of the Coal _ period. If we glance back through the geological ages we shall see _ that there were cases of the comparatively rapid extinction of types or whole groups of animals. The more remarkable were the extinction of the trilobites and ammonites, PES ; bese Darwin remarks: “The extermination of whole groups, as of ammonites toward — 1886. | some of its Apparent Causes. 39 the close of the secondary period, has been wonderfully sud- den.” In the same manner the trilobites as well as the Eurypterida ceased to exist at the end of the Palæozoic age; the Silurian graptolites disappeared with comparative suddenness ; the crinoids and brachiopods mostly, and the dinosaurs and ornithosaurs, aS well as pythonomorphs wholly perished during the Cretaceous period. The views we have presented, while opposed to ultra-uniformi- tarian ideas, have nothing in common with the Cuvierian catas- trophic doctrine of sudden, wholesale extinctions and re-creations. But known facts in paleontology postulate long periods of quiet preparation, succeeded by more or less sudden crises, or radical changes in the physical structure of continents, resulting in catas- trophies, both local and general, to certain faunas or groups of animals, as well as individual species. The biological changes were not due to climatic and geological changes alone, but it should be borne in mind that the great changes, slowly induced but not without striking final results, end- ing in the addition or loss of vast areas of land, induced exténsive migrations, the incursions of prepotent types which exterminated the weaker. The reaction of one type of life upon another, the results of natural selection, were apparent all through; but these secondary factors were active both during periods of quiet and periods of change. Here again we may quote from Darwin, the leader, next to Lyell, of the uniformitarian school, who remarks : “ We have every reason to believe, from the study of the Tertiary formations, that species and groups of species gradually disappear, one after another, first from one spot, then from another, and finally from the world. In some few cases, however, as by the breaking of an isthmus and the consequent irruption of a multi- tude of new inhabitants into an adjoining sea, or by the final sub- sidence of an island, the process of extinction may have been rapid.” Local extinctions due to local changes of level; the formation of deserts, saline wastes and volcanic eruptions and vast outpour-' ings of lava, such as took place in Oregon and Idaho during the Tertiary, with sub-marine earthquakes causing the death of fishes on a vast scale, these are quite subordinate factors, In closing this meager sketch of a subject which has not re- 40 : Editors’ Table. [ January, ceived very much attention, we have endeavored to attract notice to what we have been accustomed to regard as the main factors in the extinction of species and of higher groups. That there isa limit to the age of species as well as to individuals almost goes without saying. As there is in each individual a youth, manhood and old age, so species and orders rise, culminate and decline, and nations have risen, reached a maximum of development and de- cayed. The causes, however complex, are, in the case of plants and animals, apparently physical; they are general and pervasive in their effects, and have been in operation since life began ; there have been critical periods in palzontological as well as geological history, and periods of rapid and widespread extinction as well © as a continual, progressive dying-out of isolated species. Such extinction was, so to speak, a biological necessity, for otherwise there would have been no progress, no evolution of higher types. “OF EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE.

The proposition to create an Academy of Sciences of the State of Indiana, suggests some reflections as to the future of such bodies in the United States. It has appeared to us desirable that each State should have, at some future time, its academy of sciences, but we have refrained from enlarging on the topic, since it is plain that, as regards the greater number of States, the time has not yet arrived. But Indiana now comes to the front, and if she succeeds in establishing a real academy of sciences, she will hold the place of honor in our history. There is no doubt that among the men of her leading schools, her geological surveys, etc., she has the material for the organization of such a body. In most of the States there is no material out of which to make an academy of sciences, and in none is there much material. Of course all are agreed that merit only shall be the test of membership in such a body; but all are not agreed as to what the test of merit ought to be. There can, however, be but one test, and that is the one which has been adopted in the old coun- tries, and by our own National Academy in recent years, and that is the test of meritorious work done. It may be that this is an im- perfect guide to the merits of some men, but it is the best we have, and the one open to the fewest objections. Moreover the estimation of the merit of work done should be guided by the attribute of quality rather than of quantity, and chiefly by the quality of originality or novelty. There are many meritorious compilations, but the best of them stand in the second rank o merit. The first rank is held by thé discovery of new truths. As the amount of truth yet to be learned far exceeds that which has been acquired hitherto, its discovery is the business of the scien- tific man. Since the truths that lie at the foundation of a major- ity of phenomena are yet unknown, the work of compilation had- better be left to those who for any cause whatever are incapable of original research. In the first organization of an academy of sciences, the seeds of its future success or failure are sown. The admission of per- sons to membership who regard science as a mere ornament, or amusement, will vitiate its future life. Still more will the entrance into its councils of persons who regard membership merely as a step to personal advancement. In many portions of this country, especially in some regions where intelligance is not wanting, the fact of the specialization of men’s abilities is not sufficiently ad- -— Sangre 42 Recent Literature.

In such ~ places a fluent expression of interest in some form of human prog- ress, will be regarded as identical with ability to aid in that form — of human progress. a Since academies of sciences in this country are not yet sus- tained by government grants, it will be necessary to have a lay | membership, whose annual dues will meet the necessary expenses. — There should therefore be two degrees of association, viz., mem- | bership and fellowship; the latter to be conferred exclusively on _ persons who have contributed important work to the progress of science, chiefly of original research. Such fellowship becomes — an order of merit, which serves both as a stimulus and as are- ward for work. The local academies of science hitherto established, generally _ possess libraries and museums. This property may become a great evil, as, for instance, when its conservators claim equal place in the councils of the academy with the scientific men.

Seeing that I was really going, Francis, like a good boy, did not hesitate to follow, and we step- ped out of the sampan into mud and water hip deep. “We will never know the actual depth of the mud on that bank, but we sank into it to our knees at every step, and were fortunate enough to stop sinking at that point. What a circus it must have been for those who looked on! But, in for a penny in for a pound, and bidding Francis choose the largest fish when Possible, we went for them. There were probably a dozen in sight, hopping spasmodically about, or lying at rest on the mud, but when we selected the nearest large specimens and made for them, they developed surprising energy and speed, and made Straight for their burrows. They progressed by a series of short but rapidly repeated jumps, accomplished by bending the hinder ird of the body sharply around to the left, then straightening it very suddenly, and at the same instant lifting the front half of the ly clear of the ground by means of the arm-like pectoral fins which act like the front flippers of a sea lion.

By digging a big hole two feet deep, and standing on one’s head in the bottom of it, we were able to reach an arm down two feet farther and seize our fish at the bottom of the burrow. Lucky it was for us that they had no sharp and poisonous spines, like the mud-laff which stung me in Singapore and paralyzed my right hand for some hours. “ My first fish was hard to get and hard to hold, but in the im- mortal words of The Shaughraun, ‘ Begorra, ’twas worth it.’” In hunting tigers and elephants, the most dangerous game in - the world, Mr. Hornaday proved himself a mighty Nimrod. ‘He naturally has much to say of the elephant, and we are surprised to learn that in such a populous country as India the animal is on the increase. Though at present they are rigidly protected by law, it is evident that their number will soon increase to suc an extent “as to render further elephant shooting positively necessary.” The height of the Indian elephant is, the author claims, like that of nearly all large animals, usually recorded in exceptional figures. “ Even the best scientific writers are apt to fall into the habit of giving the largest measurements fairly obtainable, which therefore brings the average animal far below the standard they set up. I can scarcely recall an instance of having shot a mam- mal, even out of a score of the samie species, which came up to the measurements recorded by Jerdon in his Mammals of India, The height of the male Elephas indicus should be recorded as nine feet six inches, vertical measurement, at the shoulder, and the female eight feet, for these figures represent the height of from eight to twelve individuals to be found in every hundred; in other words, animals which can be seen without searching throughout the length and breadth of India.” e height of the Indian elephant is everywhere recorded as from ten to ten and a half feet, but the largest one ever measured © “was a tusker described by Mr. Corse in 1799 as belonging to Asaph-ul-Daula, a former Vizier of Oudh, which really measured ten feet six inches, perpendicularly at the shoulder. This animal was merely one out of ten thousand, and it would be quite as sensible to measure Chang and record the height of Chinamen as being seven and a half feet, as to say that the Indian elephant is as tall as the Vizier’s giant.” : Our author spent a month with the Dyaks in Borneo, orang hunting, his- trophies now adorning the National Museum at ‘Washington. His account of the two species of orang (Simia wurmbu and satyrus) inhabiting Borneo, is detailed, and stamped with the mark of accuracy. The nesting habits were observed and described as follows: “I got there just in time to see the | orang build a large nest for himself. He took up a position in a PLATE IV. RHAMPHOBATIS ANCYLOSTOMUS.

There was no attempt at weaving, nor even regularity in anything. He reached out his long, hairy arm, snapped off the leafy branches with a practiced hand, and laid them down with the broken ends sticking out. He presently got on the pile with his feet, and standing there to weight it down he turned slowly, breaking branches all the while and laying them across the pile in front of him, until he had built quite a large nest, When he had finished he laid down upon it, and was so effectually screened from us that I could not dislodge him, and after two or three shots I told the natives they would have to cut the tree.” During’ one day’s travel along the Upper Simujan river, Mr. Hornaday counted thirty-six old nests and six which were regarded as new or fresh. He thinks that an orang after building a nest sleeps in it several nights in succession, unless he leaves its neighborhood altogether. He never saw nor heard of any house-building by orang-utans, though he was led to believe that some individuals may have a habit of covering their bodies with branches for protection against the dashing of the rain drops during a heavy storm. “ My little pet orang,” he says, “ would invariably cover his head and body with straw or loose clothing the moment it began to rain, even though he was under a roof.” Forty-three orangs were shot by Mr. Hornaday and his hun- ters, and of these seven exceeded the maximum height as given by Mr. Wallace, viz., four feet two inches. ‘ My tallest Simia wurmbi or‘mias chappin, measured four feet six inches from head to heel, and the next in size four feet five anda half inches. Then a satyrus, or ‘mias rombi,’ measured four feet four and a half inches, two other warméii four feet four inches, and four feet three inches respectively, a satyrus four feet three inches, anda wurmbiu four feet two and a half inches.” The account of the gibbons and other animals of Borneo, its forests and of the Dyaks are interesting—indeed there is not a dull page in the book. Besides the general map there is an ethno- graphic map of Borneo, showing the. distribution of the Dyak tribes and subtribes, as classified by the author. Much ethno- graphic material is given, with frequent illustrations.

The whole volume thus covers the field of the general anatomy and physiology of plants, and especially of the flowering-plants. In looking over the chapters one is struck with the fact that in them much new material has been brought for the first time be- fore the American student. There is thusa freshness about much of the matter which adds greatly to its interest. The treatment, part of the matter is the result of work done in German labora- tories A noticeable feature of the book is its wider range of subjects than is usual in botanical works. There is much in it which we are accustomed to consider as belonging to agriculture and agri- cultural chemistry. This feature will commend the book to the teachers and students in our agricultural colleges. We have thus in chapter vii such topics as the following taken up and discussed at some length, viz: Formation of soils; classification of soils ; condensation of gases by soils ; temperature of soils; etc., etc. In chapter xvi we have discussed the following practical topics, viz: Winter killing ; improper food ; noxious gases ; liquid and solid poisons; mechanical injuries. The chapters which interest us most are the tenth, eleventh and twelfth, devoted respectively to assimilation, change of organic matter in the plant, and vegetable growth. In the first there is some danger of confusion from the double sense in which the word assimilation is used, viz: 1, For the conversion of all food- matter (in which sense it is employed in the heading to the chap- ter and headings of the pages throughout the chapter), and 2, the appropriation of carbon. This last is called assimilation proper (p. 285), and a few lines further on the statement is made that “ the term assimilation in the following pages will be made to refer to the appropriation of carbon.” Aside from this confusion of terms, the treatment is exceedingly satisfactory. In the eleventh chapter the word transmutation is used in place of the usual one, metas- tasis, or the less usual one, metabolism. This appears to us to be a desirable improvement in the nomenclature of the subject. The chapter on vegetable growth brings before the student the latest results of the German investigators, and this is done in so clear and concise a manner as to leave nothing to be desired, The author has sifted the great mass of literature upon this subject and siven in summary form the results, : The illustrations throughout the volume are drawn mainly from Be eee i Eo ee ee a a a ee ee 2 iris poh eh a a a i a E ET A E E ES a EE 1886.] Recent Literature. 47 the publications of Pfeffer, Sades, Darwin and others, and in many cases have been reduced in size by the publishers so as to give them a better appearance upon the octavo pages.

Woops Nature’s TEAcuHInGs.!'—Mr. Wood has written a good many books on zoological subjects, all useful, but none of them particularly profound or especially inspiring, but we think that in the present case he has produced a most readable book. The object of the writer is to show the close connection between the actions of the different organs of animals and plants and human inventions, and to prove that there is scarcely an invention by man which has not its prototype in nature. The author has placed side by side a great number of parallels of nature and art, with terse, brief descriptions, and illustrated with a great number of original sketches. As a result, we have just the book to put into the hands of a boy, not only serving to interest him but to lead him to observe the common objects of nature; and grown-up peo- ple will also, if we mistake not, relish its pages and illustrations. The author draws the corollary from the facts presented, “ that as existing human inventions have been anticipated by nature, so it will surely be found that in nature lie the prototypes of inven- tions not yet revealed to man.” As examples, the raft with its sail is anticipated by the Velella; the boat by the gnat-egg boat, the floating sea-anemone, or water- sail or pupa-skin of the mosquito; and the boatman in his boat by the “water-boatman,” or Notonecta. Examples of paddle- wheels are seen in those of the Ctenophores, and the movements of the tail of the fish anticipate those of the propeller. The arrangement of the ribs of a fish are like those of a vessel, while the form of a ship’s anchor is outlined in the spicule of the Synapta, and that of a grapnel in the spicules of sponges and Echinococcus; ice-anchors and ice-hooks are anticipated by the tusks of the walrus; an eagle’s claw presages a flesh-hook, and the grapple-plant the ordinary drag; boat-hooks are typified in the pushing spikes of sea worms ; Captain Boynton’s life-dress in the float of a Portuguese man-of-war, and Janthina’s raft in a cask- pontoon. Under the caption of war and hunting, pitfalls are shown to be but an imitation of that of the ant-lion, and poisoned arrows of the fangs of serpents and the stings of insects. Barbed Spears, harpoons and arrows have multitudes of semblances in nature, as do projectiles of all descriptions.

Cook, Director.—From this report we learn that the geodetic survey of New Jersey is completed except in the interior of the southern part, and that the topographical survey has com- pleted over three-fifths of the total area. The volume includes notices of the one forest near South Aibar. consisting of chestnut, oak, cedar, etc., in complete preservation, and probably buried since the ok aa of the country; of the glacial drift and yellow sand and gravel; of the continuation of the plastic clays, marls, etc., of the Cretaceous and Tertiary strata under the ocean for one hundred miles; of the now celebrated columnar trap rocks of Orange mountain ; of the Devonian, Silurian and Archæan areas of Northern New Jersey; of the mines and min- ing industry; artesian wells, etc., of the State. Perhaps the most interesting result given is that the slope of the sea bottom beyond the continental plateau is almost exactly the same as the dip of the Cretaceous strata. The presence of the Cretaceous beds in the marginal deposits of the ocean, as proved by borings, seems to prove the Pre-cretaceous age of the ocean bottom Pk ANNUAL REPORT OF THE GEOLOGY AND NATURAL _ Aistory Survey or Inpiana. John Collett, Director —This vol- -ume is accompanied by a geological map giving a fair exhibit of the surface geology of the State. The topographical and geo- lp see of pesg Hamilton, Fayette and Union coun- | ties, are given more in detail, and Dr. J. S. Newberry describes the ‘drift Sepai fe the State. The volume closes with an account = the mammalian fauna of the Post-pliocene deposits, by Profes- r E. D. Cope and J. L. Wortman. The Artiodactyla are Plapeonus ee ee and Cariacus dolichopsis ; the Proboscidea, Elephas primigenius and Mastodon americanus ; while the Roden- tia are represented by the singular Castoroides ohioensis, an animal exceeding the capybara in size, and, spite of its name, differing widely in character from the beaver. Megalonyx Jeffersoni repré? sents the sloth-like edentates, and the genus Equus has left the remains of two species, Æ. — and Æ. major, in the Pliocene and Post-pliocene of Indiana RECENT BOOKS AND PAMPHLETs.

Asia.—The Trigonometrical Survey of India—At the meeting of the British Association, held at Aberdeen in September of this — A the president of the geographical section, General J. T. 'alker, gave an account of thé survey of Hindostan. Survey operations along the coast-lines began before the commencement of the seventeenth century, and the first general map of India, -published by D’Anville in 1752, was compiled from the charts _ of coast-lines and the itineraries of travelers, Major Rennell, appointed surveyor of Bengal in 1764, was the father of Indian geography. In nineteen years he surveyed 300,000 square miles, ‘and after his return to England, published a great work on Indian geography. At the close of the last century Major Lambton _ drew up a project for a general triangulation of Southern India. -He commenced work by a careful triangulation of Southern ed. W.

In 1817 the French institute elected him a corresponding member, and after this honors and ap- plause followed from his own countrymen. His assistant, Captain Everest, discovered that Lacaille’s meridional arc, at the Cape of Good Hope, was in error through the deflection of the plumb-line at the ends of the arc, under the influence of the at- traction of the neighboring mountains, and thus became aware of the necessity of placing astronomical stations where this cause would not be active. Everest introduced great improvements into the methods of the survey, which, before Lambton’s death, had been extended in its scope to embrace the whole of India, and his methods were followed until the completion of the princi- pal triangulation. Many of the forest regions of India are most pestilential. Native troops mutinied at being taken into the God- avery basin, for fifty years the chain of triangles passing through it remained untouched, and its execution cost the life of the officer in charge. The Terai, at the base of the Nepalese Himalayas, was still more formidable, yet, owing to the refusal of the Ne- palese government to permit Europeans to enter their territory, a connecting chain of triangles had to be carried along its 500 miles, necessitating the clearance of some 2000 miles of line through forest and jungle, and the construction of over 100 towers to overlook the earth’s curvature. e mortality was greater than in many a famous battle. In 1843 Everest was succeeded by Waugh, who retired in 1861, and the last chain of the princi- pal triangulation was completed in 1882. The two longitudinal arcs first measured in India were employ- ed by Colonel Clarke in his last investigation of the figure of the earth, and General Walker stated his belief that they are the only twoarcs sufficiently accurate to be thus used. These investigations show that the equator has much less ellipticity than was formerly believed, and that the major axis is 8° 15’ west of Greenwich, instead of 15° 34’ east of it, as was previously supposed. The French meter, supposed to be a ten-millionth part of the earth’s meridional quadrant, is now known to be nearly ,isth part less the magnitude it was intended to represent. i Mr. Hosie’s Travels in China—At the recent meeting of the British Association Mr. A. Hosie gave an account of three Journeys in Southwestern China made by him since the beginning of 1882. The first was through Southern Ssu-ch’uan and North- ern Kweichou to its capital, Kwei-yang-Fu, westward to Yun- nan Fu, then through Northern Yunnan and along the Nan-kuang river to the Yang-tsze, where he took boat to Ch’ung-ch’ing, starting-point. In 1883 he passed to Ch’éng-tu, the capital of Ssu-ch’uan, by way of the brine and petroleum wells of Tzu-liv-» ching, then through the country of the Lolos, then by Ning-yuan, : in a valley famous as the habitat of the white-wax insect, to and a through the mountainous Cain-du of Marco Polo, inhabited in 52 General Notes. (January, great part by Mantzu tribes. Reaching the Chin-sha Chiang or river of golden sand, he then proceeded to Ta-li Fu and Yunnan Fu, when he descended the Yung-ning river to Lu Chou. In 1884 he went to Ho Chou, north of Ch’ung-Ch’ing, thence through a cultivated and fertile country to Chia-ting Fu, on the right bank of the Min and thence south on the eastern side of indepen- dent Lolodom, to the river of Golden Sand at the town of Man-i- ssu. Chia-ting is the great center of sericulture in Ssu-ch’uan, and the chief insect wax-producing city in the empire. A day’s journey from it is the famous mount O-mei, 11,000 feet high, sacred to the worship of Buddha. Asiatic News.—The total forest area of British India is com- puted at 75,270 square miles, Colonel Prejevalsky has again failed to penetrate into Tibet over the Keria mountains in conse- quence of the strenuous opposition of the Chinese. Dr. Otto Finsch has explored 1000 miles of the coast of Northern (Ger- man) New Guinea, has discovered several good harbors, and has followed a large river thirty miles into the interior. The interior is mountainous, the plains near the sea are richly covered with trees and bush and well watered, the soil is of the richest fertility, and the natives are friendly. Dr. Finsch found no trace of min- erals, and regards the reported discovery of gold on the Fly river ss »”» as a “ schwindel. Arrica.—Somaliland—The October issue of the Proceedings of the Royal Geographical Society, contains F. L. James’s account of his journey through the Somali country to the Webbe Shebeyli. The journey was in many respects the most successful that has ever been made in that region, since the party succeeded in pene- trating Ogadayn, more than half crossing the peninsula, and returning without a contest. The return was, however, compelled by the attempt of the Sultan of Barri to make his visitors assist him against his rival. The greatest danger to which the travelers were exposed, arose from Lord Granville’s telegram forbidding the expedition to proceed, This arrived after their departure, but - its open publication in Berbera caused the Somali to believe that the travelers were in disfavor with the British government. Fire- arms were new to the Somali of Ogadayn, and the rifles insured respect. Most of the country appears to be a stony desert, but settlements are abundant on the Webbe, which does not reach the ocean, but loses itself a few miles from the coast. In Ogadayn there is a subject people called Adone, with strongly-marked ` negro features. About 150 species of plants, chiefly herbs and under-shrubs, were brought back, including a specimen of an , apocynaceous plant which affords an arrow- poison. Sixty-one species of birds, seven of which are new, and forty-six kinds ga l Lepidoptera, seventeen of them new, were also brought back. The genealogy of the Somali tribes is given. They are all said 1886. } Geology and Paleontology. 53 to be descended from two brothers, Darode and Tsak, Ogadayn was a son of the former. The Lake Moris —Mr. Cope Whitehouse described to the British Association the basin of the Reian Moeris in Egypt, and spoke of the possibility of the restoration of this historic lake. South of the Fayoum exists a depression of several hundred square miles, not less than 150 feet below the Mediterranean, and in the parts visited by the writer, 175 to 180 feet deep. The area is irregular, curving like a horn from near Behnessa to the ridge which separates it from the Fayoum. Ruins exist in its southern part. The level of the ruins proved that the ancient station of Ptole- mais might have been as shown in the text and maps of Ptolemy, _ onahorn-shaped lake about thirty-five miles long and fifteen wide. The Kassai Tributary of the Congo—Lieut. Wissman speaks enthusiastically of the Kassai as a magnificent fluvial artery, fre- quently of enormous breadth, leading into the heart of the new Congo State. The country on its banks is of wonderful fertility. During the forty-two days occupied in the voyage from Luluaburg to Kwamouth, the health of the expedition was excellent, the five whites and 200 negroes all arriving in good health at Leopold- ville on July 16th. The Sankaru and Lubilash are one river, which turns westward, and joins the Kassai. The Kassai receives the great Koango, and enters the main river by the Kwamouth, after receiving the waters of Lake Leopold. African News——The country between Blantyre and Quilli- mane has heen described by Mr. H. E. O'Neill and Mr. D. J. Rankin in the Proceedings of the Royal Geographical Society. The Portuguese authority has recently been considerably ex- tended up the Shiré towards Lake Nyassa. The Kassai, the great southern tributary of the Congo, instead of entering the main stream north of the equator, joins it in 3° 13’ S. lat. Mr. D. D. Veth, leader of a Dutch expedition into Portuguese West Africa, died on May toth, between Benguela and Humpata. GEOLOGY AND PALÆONTOLOGY. INTERNAL CHEMICAL AND MECHANICAL EROSION A FACTOR IN Continent AND Mountain Buitpinc.—As soon as it is affirmed that since early Laurentian times the great continental folds and depressions have not’ changed places, so soon it becomes neces- Sary to explain how these great ridges and troughs have per- sisted, as such, in spite of the amount of erosion and sedimenta- tion which are known to have taken place and which we know to be still going on at no small rate. Either the pre-Laurentian equalities of surface were vastly greater than they are now, or €, during all the ages the ocean beds have been constantly re- ceiving sediment and sinking, while the continents have been as _ Constantly eroded and rising. But this latter hypothesis implies 54 General Notes. [January, that there has been and is a continuous circulation of the mate- rial of the solid land from the continents to the ocean, and from the ocean back to the continents again, a circulation, in some de- gree, like what is taking place in the ocean between the equator and the poles, that is, a bodily transfer of superficial materials one way and a siow general under-creep of materials back. But how is sucha system possible and how can it be maintained ? If we assume, as appears to be required by both physical princi- ples and geological facts, that the earth’s surface is only slightly out of equilibrium and is constantly tending toward that state, then any transfer of material from the continents to the ocean would cause a subsidence of the ocean beds which, in turn, must necessitate a setting of the deeper earth materials from beneath the ocean beds toward the continents causing them to rise. This cir- culation appears to be entirely possible and even probable, if not almost certain, and this too, while granting that the earth is essen- tially solid throughout and as rigid as glass. By this is meant, of course, as rigid as glass would be under the internal earth pres- sure from the views expressed by leading physicists in regard to the rigidity of the earth for, as I see it, there may be all the rigidity which physicists have claimed and yet all the mobility geological facts can demand. When cold metals are subjected to artificial pressure, causing their molecules to flow into new positions so that the form of the mass is greatly changed, it is not to be sup- posed that these metals while under such pressure are to be re- garded as true liquids, in any sense obedient to all the laws of fluids, nor could any mere pressure, however great, convert them into true liquids. I think it will not be maintained, even by those who believe “pressure itself would reduce the interior of the earth to a fluid condition,” that this fluid is such to the extent of permitting bodies moving freely through it as fish move through the sea; nor would they maintain that this interior fluid would remain such with the pressure removed. It could hardly be maintained either, that such a fluid would possess the degree of elasticity characteristle of true fluids, but unless these are insisted upon by geologists, physicists have all the rigidity they have claimed. Even if it is admitted that such a circulation is possible when con- ditions are once favorable, unless there is some disturbing agent continually working to destroy the equilibrium which the circu- lation tends to establish, eventually the earth’s surface must have existing differences of level greatly reduced. There appears no escape from the conclusion that the density of the earth increases as its center is approached. This being the case, a continual denu- dation from certain regions and constant sedimentation in others must, in due time, whatever may have been the original distribu- i It appears to me, geologists have no occasion for dissenting + 1886.] Geology and Paleontology. 55 tion of density near the earth’s surface, remove all materials of low density from the continents and place them over the sea bot- tom, while the elevation of the denuded region would bring den- ser materials to the surface, thus tending to restore equilibrium with the two surfaces more nearly on the same level, unless there is some agent operating to reduce the average specific grav- ity of the continents. If the earth does increase in density toward the center, this may be due : first, to a difference of chemical composition ; or second, to increasing pressure; or third, to these two conditions in combi- nation. With either the first or third conditions existing, and continued denudation with no counter agent, a leveling up would inevitably result. With the second condition existing, unloading in one place and loading in another of equal area, would permit of expansion in the continental mass and cause a compression of strata under the oceans, and might maintain the differences of level already established ; but this view being very improbable, it re- mains to search for some cause which may reduce the specific gravity of the continents, and an adequate one, it seems to me, may be found in internal chemical and mechanical erosion. Taking Mr. T. M. Read’s estimate of chemical erosion (Am. Jour. Sci., April, 1885), at 100 tons per square mile annually on the average the world over, as a fair estimate of the work done by the waters which come to the surface before emptying into the ocean, it is plain that a vast work must be done in reducing the average specific gravity of the continents, unless it is maintained that the small cavities produced are closed by compression as fast as formed. This certainly is not the case in the superficial strata, nor can it be the case in the deeper strata where the cavities pro- duced by solution remain filled with water. Data are altogether too meager to allow of a quantitative treat- ment of the question. We do not know, for example, what propor- tion of the matter carried in solution to the sea by rivers annually is obtained through purely superficial action. Neither do we know what proportion of the water falling upon the continents enters the ocean below ocean level. It is reasonable to suppose that this amount is not small, and that the water entering the sea below ocean level carries a higher per cent of solids than the average river water. Now that our Government scientific work is being consolidated, it would seem eminently fitting that these fun- damental questions should occupy the joint attention of the U. S. logical Servey and the Signal Service, and they are possibly already under consideration. This internal erosion, by excavating small cavities in the body of the continents, would lighten them without in the same degree lowering their surfaces, and existing differences of level would be longer, if not permanently, maintained, because in case the denser strata were to be thrust up into the heart of the continents, into the 56 ; General Notes. | January, region of aqueous action, they would be attacked by the water and their average specific gravity lowered. Now in case superficial ero- sion were to exceed internal erosion, the result would be a lowering of the continents ; but any lowering of the continents would reduce the rate of mechanical erosion much faster than it would the chemical, because very feeble springs and the mere capillary up- draught of saturated water, would remove the solid ingredients of the continents and place them in position to be drawn off to the sea by currents too feeble to bear much solid material in suspen- sibn. The specific gravity of the continents would, by this means, be continually lowered, and the oceanic areas as continuously loaded, and, for this reason, we might expect the continents and oceanic basins to persist. Again, even if we suppose the same degree of porosity to exist in the sedimentary beds under the ocean as exists in those of the continents and the materials of the two to have the same specific gravity, the same number of feet of sediment under the ocean would be heavier, volume for volume, _ than the land because, if for no other reason, the beds would be, in all probability, more fully saturated with water. Now Pro- fessor Ferrel has shown that the attraction of continental plateaus must be neglected in reducing both pendulum and barometric ob- servations to sea level, and therefore they do not represent so much material added between a given station and the earth’s cen- ter; that is, these earth masses, although possessing longer radii, are no heavier than equal sections in the ocean areas. Assuming that the continents and ocean beds, with their super- incumbent. water, are essentially in equilibrium, and taking the average depth of the oceans as 15,000 feet and the average height of continents, above sea level, as 1000 feet, we could obtain a tolerably accurate estimate of the average specific gravity of the continents if we knew the average density of the rocks below the sea bottom, knowing, as we do, the specific gravity of 15,000 feet of superimposed matter. The specific gravity of the earth 400 miles below the surface is estimated at 4.0478 (U. S. Coast and Geodetic Survey, 1879), and our heaviést known rocks scarcely run above 3. From these considerations, and from what we know of the specific gravity of sedimentary rocks, we should not expect the sedimentary beds of the sea bottom to have a specific gravity much above 2.5. Assuming an average of 2.5 for the first 5000 feet below sea bottom and of 2.95 for the next 10,000 feet, then the average specific gravity of the continental mass required to exactly balance this would be 1.851, assuming, of course, that a surface of uniform density under both oceans and continents is reached at a depth of 30,000 feet below the sea level. Now con- sidering the specific gravity to increase below 15,000 feet below sea bottom at the rate of .05 for every 10,000 feet downward, it would then be necessary to go to a depth of about thirteen miles below sea level to obtain an average density sufficiently large to a 2 š ive rece Pe pS BEE GE ES aR Pn RN RTE E 1886. ] Geology and Faieontology. 57 balance continental masses having an average specific gravity of 2.5. Ifthe specific gravity does not increase downward as rap- . idly as the rate assumed, as we may infer from Mr. Pierce’s table » (U. S. Coast and Geodetic Survey, 1879, p. 200), then a still greater depth would be required to secure equilibrium. From these considerations it would appear that the superficial continen- tal strata must have an average specific gravity much below 2.5 and, in order that this may be so, that much material must have been removed from within the mass.—/.

GEOLOGICAL Survey oF Betcium—In 1878 a commission was appointed to undertake a more exhaustive invéstigation of the geology of Belgium than that embodied in the map of Dumont. The topographical map serving as a basis consists of 369 sheets. Each important group of formations is entrusted to one or more specialists, who are each furnished with two assistants, and trace the system completely across the country. Every actual outcrop of rock is marked on the map, and where the rock is fossiliferous the fossils are noted. Special attention is given to soils and su soils, and care taken to express on the map the agricultural char- acter of the ground. It is believed that one-third of the entire work of the survey is now completed. By a novel system of broad washes of subdued tints, M. Dupont, the head of the sur- vey and Director of the Royal Museum at Brussels, contrives to show the surface deposits, as well as the formations below, which are shown in deeper tints; while shaded lines of the proper color mark the margins of the stage. Professor Archibald Geikie ex- presses in Nature his conviction of the success of the new system of cartography. THE BED or THE Ocean.— The Tuesday evening discourse during the late meeting of the British Association was delivered by Mr. J. Murray, F.R.S., of the Challenger expedition, who took for his subject the “ Bed of the ocean, and some results of the expedi- tion.” In commencing his lecture, Mr. Murray traced the devel- opment of geographical knowledge from the crude conception of the ancients down to the ‘extended knowledge of the nineteenth century. It was not easy, he said, to estimate the relative impor- tance of the events of one’s own time, yet, in all probability, the historians of the reign of Victoria would point to the recent dis- coveries in the great oceans as the most important events of the century with respect to the acquisition of natural knowledge—as ong the most brilliant conquests of man in his struggle with - Rature; and doubtless they would be able to trace the effects of these discoveries on the literature and on the philosophic concep- _ tions of our age. The last of the great outlines showing the sur- . face features of our globe had been boldly sketched ; the founda- a tions of a more complete and scientific physiography of theearth’s 58 General Notes.

The lecturer then briefly de+ scribed the chief surface features of the globe, the action of wind and water and ocean currents; referred to the temperature of the sur- face of the sea, and explained that the most important, as well as the most direct, effect of the unequal distribution of temperature over the surfaces of the oceans and continents was an unequal dis- tribution of atmospheric pressure, varying more or less with season. e then proceeded: The advances during recent years in the knowledge of one form of life inhabiting the floor of the ocean surpassed those in any other department of oceanic investi- gation. Thousands of new organisms had been discovered in all seas and at all depths in the ocean, and either had been or were now being described by specialists in all quarters of the world. There did not seem to be any part of the ocean bed so deep, so dark, so still, or where the pressure was so great as to have effect- ually raised a barrier to the invasion of life in some of its many forms. Even in the greater depths all the great divisions of the animal kingdom were represented. As they descended into the deeper waters, and proceeded further seaward from the borders of the continents, species and the number of individuals became fewer and fewer, though they often presented archaic or embry- onic characters, till a minimum was reached in the greatest depths furthest from continental land. Distance from continental land was, indeed, a much more important factor in the distri- bution of deep-sea animals than actual depth. If they neg- lected the Protozoa and compared the results of twelve of the Challenger's trawlings and dredgings in the central line of the Pacific, in depths greater than 2000 fathoms, on globigerina ooze, radiolarian ooze, and red clay, with twelve trawlings and dredgings taken under similar conditions and depths, but on the blue and green muds within 200 miles of the continents, they found that the central Pacific stations yielded ninety-two specimens of ani- mals belonging to fifty-two species, all—with two doubtful excep- .tions—new to science, and among them thirteen new genera. On the other hand, the stations near the continents gave over 1000 specimens, belonging to 211 species, of which 145 were new spe- cies and sixty-six belonged to species previously known from shallower water. Although no new types of structure had been discovered in organisms from the deep sea, the peculiar modifica- 3 tions which animals had undergone to accommodate themselves to abysmal conditions were sufficiently interesting and remarka- ble. The eyes of some fish and crustaceans had become atrophied or had disappeared altogether, while in others they had become of exceedingly large size, or been so modified as to be scarcely recognizable as eyes. Fins and antenne had become extraordi- . narily elongated, and at times appeared to simulate the alcyonarians ofthe deep sea. The higher Crustacea and some families of fish had very few and very large eggs in the deep-sea species, while their _ i PF i ii - —_ 1886. | Geology and Paleontology. 59 shallow-water representatives had a very large number of very small eggs; showing apparently that the deep-sea species had rel- atively few enemies. Many deep-sea animals emitted, and some had special organs for the emission of phosphorescent light, which appeared to play a large vd/e in the economy of deep- sea life. One of the most striking facts with respect to deep- sea animals was their very wide distribution, the same spe- cies being found in all the great ocean basins. After referring to examinations of coral atolls and barren reefs, Mr. Murray said the results of many lines of investigation seemed to show that in the abysmał regions they had the most permanent areas of the earth’s surface, and he was a bold man who still argued that in Tertiary times there was a large area of continental land in the Pacific, that there was once a Lemuria in the Indian ocean, ora continental Atlantis in the Atlantic. It mattered little whether the opinions which he had given as to the bearing of some of the researches be correct or not. The great point was that there had been a vast addition to human knowledge, and it must be a mat- ter of satisfaction that our own country had taken so large a share in these important investigations as to call forth the admiration of scientific men of all countries. In the matter of deep-sea inves- tigation, neglecting mere details, we could say that successive governments during the past twenty years had, either from design or by accident, undertaken a work in the highest interests of the race, had carried it on in no mean or narrow spirit, and were likely to carry it to a termination in a manner worthy of a great, free and prosperous people. GrotocicaL News.—General—The third International Con- gress of Geologists has just been held in Berlin, 255 members be- ing present, the majority Germans. Italy sent eighteen, Austria sixteen, Great Britain eleven, France ten, and the United States nine representatives. The most important work of the congress is the preparation of a geological map of Europe. It is expecte that next year proofs in color of many of the sheets will be ready. The unification of geological nomenclature does not appear likely to be realized, but the congress has agreed that the Archzan rocks shall be divided into sections according to their petrographical characters, without expressing any opinion as to their relative age. Jurassic—At the recent meeting of the French Association, M. Cotteau stated that the Jurassic strata of France have furnished 125 species of Echini, belonging to fifty genera, two only of which, idaris and Stomechinus, subsist at the present day. The shal- low seas of the Jurassic epoch, full of islands and coral reefs were favorable to the development of Echini. pep- lished, in the Paléontologie francaise, descriptions of 209 cfinoids — found in France. Of these eighty-nine were new to science; i t M. Loriol has pub 60 General Notes. [ January, while the Echini were most abundant in the Bajocian stage of thè Jurassic, the crinoids attained their maximum in the Oxfordian, After the Sequanian they suddenly diminish, and only one spe- cies occurs in the Portlandian. Quaternary.— At Ternefine near Maseara sr be teeth of two species of Elephas (E. atlanticus and E. melitensis) have been found, also Rhinocerus mauritanicus, a hippopotamus and Came- lus thomasi. The last is of about the size of the dromedary, but differs in the shape of the palate and jugal bones. With these were found a horse rather larger than the zebra, some antelopes, an ox, and a single bone of a swine. Roughly-shaped hatchets of limestone or coarse sandstone show the presence of man, but no remains of the domestic dog and no bones marked by the teeth of Carnivores were found. The presence of a large number of the cotyloid cavities of the pelvis of the elephant seem to indicate that they were used as utensils, and the numerous canines and incisors of the hippopotamus found were probably employed as weapons. MINERALOGY AND PETROGRAPHY.! AMERICAN MINERALS.—Quartz.—Vom Rath describes’ quite a number of complicated forms on the quartz crystals: from Alex- ander and Burke counties, N. C.

In the November number of the Naruratist, fayalite was mentioned as having been found by Mr. J. P. Iddings i in the lith- ophyses of the obsidian and rhyolite from the Yellowstone Park. About the same time C. A. Tenne, of Berlin, found the same amai black crystals in the lithophyses of obsidians from the de aE Navajas, Mexico..

Microcuemicat REACTIONS.—It is often possible by means of a few simple chemical tests to determine the character of a min- eral under the microscope without the trouble of separating and analyzing it. The methods in most general use for this purpose are those of Streng! for the detection of apatite and nepheline, of Knop? for the minerals of the Hauyne group, of Boricky® for the feldspars and of Behrens‘ for the characteristic elements of many other minerals. These and a great many others have been de- scribed at length in the various mineralogical magazines, but have not, until very lately, been collected and put in shape for ready use. Dr. Haushofer, of Munich, has recently brought together all those methods which have stood the test of experience, an ` to these has added others of his own. The result is a compact little book® containing minute directions for the detection of fifty’ elements by means of simple tests, most of which may be appli to the rock section or mineral particle on the stage of the micro- scope. The illustrations are good and the directions for working _ clearly given. I APHIC News.— E.

After some informal consultation, the matter was left in the hands of the originators to be managed as they thought best. Accordingly, notices were grayi, Lilium grayi ella repens, Epigea repens.

Upon the hoop of the pedestal the following legend is engraved : TRIO N } Jai v eighteenth—1885. Asa GRAY, In token of the universal esteem of American botanists. The vase, accompanicd with the cards of one hundred and eighty botanists, was presented without formality on Wednesday morning, the 18th of November. It is a very pleasant duty to record in the NATURALIST the con- summation of such a fitting plan of showing the esteem in which the name of Asa Gray is held by the botanists of America. That the days of the genial doctor among us may be prolonged for many years is the fervent prayer of every botanist. CATALOGUE OF THE PLANTS oF NorTH AMERICA. — Every bot- anist who has charge of a considerable collection of plants has felt the need of a convenient check-list of North American plants. The old Gray Catalogue, which was followed by the Mann Cata- logue, both confined to the plants included in Gray’s Manual, and later, the more extended list compiled by A. H. Curtiss, served a good purpose. These, however, included a comparatively small part of the species of the whole continent, and the botanist who added Western species to his collection was left without the means for noting his accessions. This want is now supplied (in part, at least) by the Catalogue of the Phenogamous and Vascu- lar Cryptogamous plants of North America (north of Mexico) compiled by J. H. Oyster, of Paola, Kansas. It contains entries of 9867 species. The arrangement of Choripetalze and Gamopetale conforms very nearly with that of Bentham and Hooker’s Genera Plantarum. For some unexplained reason the arrangement of Apetalz and the Monocotyledons is not that of the Genera Plan- tarum, an unfortunate feature which might easily have been avoided. The species of each genus are arranged alphabetically, as is proper in a check-list. The proof-reading has been carelessly done, and the printing is not of the best; yet, with all its faults, the pamphlet is worth the price charged for it ($1.00), and will — serve a good purpose. Tue De Canpotie Prize.—The Physical and Natural History Society of Geneva offers a prize of five hundred francs for the best monograph of a genus or family of plants. The manuscript may be written in Latin, French, German, English or Italian, and should be sent to M. le President de la Société de Physique et d’Histoire Naturelle de Genève, a l’Athenée, Genève, Switzerland. —Gardner’s Chronicle. ‘ _ Tue DRYING oF WHEAT.—Experiments were made in 1384 at ` the New York Agricultural Experiment Station upon the loss of water by wheat in drying.

Winter usually stops all work except in the laboratories when “ pickled” specimens are dried and exam- ined microscopically, Perhaps in a few cases the green-house may supply unseasonable specimens for class or laboratory study ; ut this is not the study of plants in winter that we refer to. All our perennials have winter states which are full of interest to the Student. The writer of this note has taken classes of young peo- ple, who knew nothing of botany, and set them at work in mid- winter studying the out-of-door vegetation, with nothing but their eyes, pocket-knives, pencils and note-books in the way of appa- ratus and helps. The structure, position and functions of buds, the structure of twigs and branches, including wood, bark and Pith, the structure of the fruits and seeds, of various trees and shrubs, were taken up in succession, with constantly increasing No text-book was used, the pupil depending upon his — own resources entirely. By the time that spring came with its bursting buds, its leaves and its flowers, these trained young eyes were eager for their study. : Tue BOTANICAL VALUE oF A ALE That Many of the so-called agricultural experiments should have a ` VOL. XX—no, 1, ; , 66 General Notes. [ January, high botanical value is evident to every scientific man, but it is a melancholy fact, which does not speak well for the accuracy of the experimenters, that very little of their work has been of use in scientific botany. In the experiments recorded in the third annual report of the New York Agricultural Experiment Station, we have a notable exception to the rule. Many of the results obtained have a high value to the physiological and pathological botanist. Thus we find such topics as the following, viz: The hygroscopic properties of grains; Hybrid barley; Germinations of commercial seeds; The cross-fertilization of maize; A classifi- cation of maize, with a description of the species and varieties (with plates); A classification of the agricultural species of gar- den peas; The size and distribution of roots of various plants determined by washing away the soil; A classification of barley and oats ; Report of the botanist upon diseases of the pear, apple, quince, peach, tomato, oats, clematis and Canada thistle. Topics like these, treated as these are, command the respect of scientific men. We hope to see the time when such will be the rule, and not as now the exception. We hold that every agricultural experiment which has to do with plants must be sufficiently accurate to commend itself to the agriculture. Such an experiment which has no botanical value cannot haye a permanent agricultural value. The demands of scientific botany are in no wise more exacting than those of sci- entific agriculture. FERTILIZATION OF TEUCRIUM CANADENSE.—Of interest to Amer- ican botanists is the proterandry of the American germander, simulating that of T. scorodonia of Europe. The corolla here is not bilabiate as usual in this family, but the tube is split open above as far as the calyx and the five lobes are arranged on one —lower—lip. In the bud the lowest or middle lobe turns up over the stamens and style, serving as a protection to them. This lobe is embraced by the two lobes on either side, and these in turn by the two upper lobes, which usually form the upper lip in the Labiate, In their first state, as in almost all flowers of this family, the stamens are curved forwards so as to come into more ready contact with the body of the entering insect, in this case usually a bee. The stigma is bent forwards like the stamens, but the stigma lobes having not yet opened, cannot be fertilized: Later the stamens bend far backwards, and since there is n° upper lip to check this motion they actually recurve at times. The style in the meantime retains its position or takes a slightly _ higher position, while its stigma lobes open. The stamens themselves may be short and these are usually of almost equal length, or one or more of them may continue growth and even equal the style in length. There is no regularity, how- | : a 1386. | Botany. 67 ever, in their unequal development, but if the visits of bees should become less frequent, this variation would offer a means of self-fertilization, and would soon become fixed in all individ- uals of the species. The proterandry in this species is not per- fect. The stigmas sometimes mature, I might almost say, precociously, and the stamens in turn often contain good pollen when the stigma lobes open. Again, the visits of bees seem to be less frequent in this part of the country than is usual with cross-fertilized Labiate, so I suspect that even the casual irregular growth of the stamens, is in some way correllated with this fact—Aug.

A valuable feature of the work recorded is its bio- logical character. One lays down the pamphlet with the feeling that much work can be done upon the basis of Dr. Trelease’s observations. This record is an incentive to further study. r.

The January Botanical Gazette will contain a portrait and biographical sketch of Dr. Asa Gray, together with some of the poems, congratulatory addresses, etc., which were sent on his birthday, November 18, 1885. ENTOMOLOGY. Recent Discovery oF CARBONIFEROUS InsEcTs.—A rich deposit of Carboniferous insects has been discovered at Commentry, in the department of Allier, France, and has been worked up by C. Brongniart, whose work, however, has not yet been received. From a notice of his paper in the Axtomologische Nachrichten for November last, we learn that over 1300 specimens of insect remains, not wings alone but also the bodies, have been preserved to science. While an exclusive study of the shape and venation of the wings must necessarily have led to many errors, the discoveries at Com- mentry show that insects which are regarded as among the most ancient are still surprisingly like those of the present time, and only differ in comparatively unimportant respects. In the oldest strata, the Silurian, has been found but a single winged insect, the still very problematical Palgoblattina douvillet rong.; in the Devonian only the six species of insects, as to whose relations excellent naturalists, such as S. H. Scudder and H. Hagen, have very different views, and relative to which dis- cussion has not yet closed. Before the present discovery only 120 specimens of Palzeozoic insects were known. From the Carboniferous formation of Commentry Brongniart has obtained over 1300 examples. Among them occurs the first fossil Thysanuran, represented by forty-five specimens. It differs from existing forms only by having a single caudal filament, and exclusive of this is 15 to 22™™ long, and is generally similar to Machilis; it is named Dasyleptus lucasi. Numerous representa- tives of our recent Acridians are brought together under the = 1886. ] Entomology. 69 name of Palzacridiodea, and divided into three groups with seven, mostly new, genera. The types-so discovered belong to the three orders of Orthop- tera, Neuroptera, and Hemiptera, also to the Heterometabola of Packard and of Scudder, while the Metabola are still entirely wanting. But of the Heterometabola the Coleoptera are entirely wanting. Between the Orthoptera and Neuroptera is placed the new order of Neurorthoptera, with the sub-order of Neurorthoptera in a special sense, and the Palzodictyoptera of Goldenburg; the first of these suborders embraces two families, the progenitors of the recent Phasmidz, the Protophasmida, with genera containing the colossal forms: Protophasma, Lithophasma, Titanophasma and Arche- gogryllus, and the Stenaropterida with three genera. To the Palzodictyoptera belong the Stenodictyoptera with the genera Eugereon Gold., Haplophlebium Scudd., Goldenbergia Scudd., Dictyoneura Gold., and two new genera wholly without recent representatives; in addition, the Termes-like Hadrobrachy- poda, with Miamia Scudd., and the new genus Leptoneura, besides the wholly extinct Platypterida provided on the end of the abdo- men with two filaments, which belong to the three genera, Lampro- ptilia, Zeilleria and Spilatera. In the Pseudoneuroptera Brongniart places the wholly extinct family of Megasecopterida, with eight new genera whose relatives in part bore respiratory appendages on the abdomen, a group to which also belongs de Borre’s much-discussed Breyeria borinensis. Also a family of Protodonata, regarded as the forerunners of the recent Libellulide, with Protagrion n.g. Likewise, thirdly, the mily of Homothetida Scudder; also, new families, the forerun- ners of the recent ones, viz: the Protephemerina, Protoperlida and Protomyrmeleonida. Of the Hemiptera five different genera belonging to the Ho- moptera have been found, among which belongs, in Brongniart’s opinion, Phthanocoris occidentalis, erroneously regarded by Scudder as a Heteropteron.

He rejects the mosaic theory of vision proposed by Müller, following Exner in his essay on the perception of move- ments, and on the theory of compound eyes, presented to the Vienna Academy in 1875. The work of Exner, says Plateau, leads to the theoretical deduction that insects and other Arthropods possessing com- pound eyes do not distinguish the form of objects. Exner sup- Poses that, in the Articulates and in many other animals, vision Operates in a different way from that generally admitted, and 70 General Notes. [January, consists mainly in the perception of movements. He enumerates, in support of his thesis, a series of important facts. In man the power of plainly distinguishing forms only belongs to the cen- tral part of the retina, while we perceive movements very well by the aid of the peripheral region of this sensitive layer. Most animals, both vertebrates and invertebrates, seem but little impressed by the form of their enemies or of their victims, but their attention is immediately excited by the slightest dis- placement. Hunters, fishermen and entomologists have made in this respect numerous and demonstrative observations, Finally, though the production of an image in the facetted eye of the insect or the crustacean seems impossible, we can easily conceive how the Arthropod can ascertain the existence of a movement. Indeed, if a luminous object is placed before a com- pound eye, it will illuminate a whole group of simple eyes or facets; moreover the centre of this group will be clearer than the rest. Every movement of the luminous body will displace the center of clearness; some of the facets not illuminated will first receive the light, and others will reénter into the shade; some nervous terminations will be excited anew, while those which were so formerly will cease to be. In résumé, careful physiologists, relying on the structure of the compound eyes of Arthropods, admit that these animals do not see the form of objects, but only perceive colors and movements. Their facetted eyes are not complete visual organs, but simple organs of orientation. Plateau then details the experiments he made to determine this question ; and which we cannot well abstract. He calls attention to one result of his experiments: that insects only utilize their eyes to choose between a we luminous orifice in a dark cham- ber, or another orifice, or group of orifices, equally white. They are guided neither by odorous emanations, nor by differences of color. A fact which will certainly astonish all entomologists and likewise surprise the experimenter himself is, that bees have as bad sight and comport themselves almost exactly as flies. From numerous experiments on Diptera, Hymenoptera, Lepi- doptera, Odonata and Coleoptera, Plateau comes provisionally to the following conclusions: 1. Diurnal insects have need of a quick, strong light, and can- not direct their movements in partial obscurity. ‘ 2. In diurnal insects with compound eyes, the simple eyes offer so little utility that it is right to consider them as rudimentary ‘ensity as well as by the apparent excess of surface. In short, they do not distinguish the form of objects, or, if they do, distinguish them very badly. 1886. ] Zoology. 71 THE Division OF THE SEXES OF HyMENOPTERA.—We translate in a rather clumsy way Fabre’s interesting article on this subject, published in the Annales des Sciences Naturelles (Tome xvii, Nos. 5 and 6). The entire article should be read to understand the subject. The Osmias, the Chalicodomas and, as the closest analogies show, a great number of other honey-making Hymenoptera, arrange their egg-laying in female at first and then in male cells, when the two sexes have a different size and require unequal quantities of nourishment. If there is an equality of size between the two sexes, the same succession may exist, but less constantly, This binary arrangement disappears when the place chosen for the nest is not large enough for the entire egg-laying. Then par- tial egg-layings occur, composed both of females and of males, and in harmony, as to their number and distribution, with the dis- engaged space. To be able to give to each larva the room and the nourishment which it needs according to whether it is male or female, the mother decides the sex of the egg she is about to lay. Accord- ing to the conditions of the home, often the work of another or a natural habitation slightly or not at all modifiable, she lays at her will either a male or a female egg. The division of the sexes is Subject to her will. he same prerogative belongs to the carnivorous Hymenoptera, the sexes of which have a different shape, and therefore need one - More, the other less food. The mother must know the sex of the egg she is about to lay; she must dispose of the sex of this egg so that each larva shall obtain the right amount of food. _ Ina general way, when the sexes are of different size, every insect which collects the living prey, which prepares or at least chooses an abode for its offspring, must decide the sex of the egg to satisfy without error the conditions imposed upon it. It remains to tell how this elective determination of the sexes is made. I do not absolutely know, I have never understood this delicate problem but attribute it to some fortunate circumstance which it is necessary to know or rather to watch for. EnTomotocicaL News.—From a series of experiments by Pro- fessor Graber, says Nature, Oct. 22, relating to the effects of odor- ous matters on invertebrate animals, it appears probable that in the case of many insects neither the antennz nor the palpi can be absolutely pronounced the most sensitive organ of smell, inasmuch as the one organ is most sensitive to some odorous matters, and the other for others. —- Apropos of Hickson’s account of the structure of the eyes of insects in our last number, we may say that, in 1883, B. T. Lowne published a paper in the — Proc. Roy. Soc. London, of which an abstract has been published by Dr. Mack in Psyche, as follows: The author claims four forms fe 72 General Notes. [ January, of eyes: simple ocellus, compound ocellus (larval insects), aggre- gate (Isopoda) and compound eye. A brief description of each is given. Discarding all previous theories of vision by compound eyes, it is held that “ a continuous picture, a mosaic of erect mag- nified central portions of the several subcorneal images, falls upon the retina.” Kraepelin (Ueber die geruchsorgane der Glie- derthiere), Osterprogram der Realschule des Johanneums, Ham- burg, 1883, gives an historical sketch of the olfactory organs of Arthropods, followed by a bibliographic list (59 numbers) grouped according to the languages in which the articles were written. He criticises the results of others, and compares them with his own observations on several crustacea, beetles, chrysopa, Orthop- tera, butterflies, flies and Hymenoptera (Psyche, 296). In the Annales des Sciences Naturelles (xvir, Nos. 5 et 6) is an interesting article by J. H. Fabre on the division of the sexes in the Hymenop- tera; it gives the results of many- years observations on the subject which we refer to more at length elsewhere. The Transactions of the American Entomological Society (xu, No. 2) contain sev- eral papers by Dr. Horn, viz: Descriptions of new North Ameri- can Scarabaeide; Contributions to the Coleopterology of the United States; Descriptions of new Cerambycide, with notes; Synopsis of the Throscide of the United States; while Mr. F. Blanchard discusses the species of Canthon and Phanzus of the United States, adding notes on other genera; and Mr. W. H Ashmead remarks on the cynipidous galls of Florida, giving descriptions of new species. ZOOLOGY. Livinc AND Deap Protoprasm—Dr. Oscar Loew read an important paper before the British Association on a chemical dif- ference between living and dead protoplasm. Protoplasm, it was found, contains certain aldehyde groups, which account for the extreme mobility and readiness of change in living protoplasm. These aldehyde groups can be reduced by alkaline silver solution. Spirogyra, one of the lower algz, acts on this solution in a pecu- liar way. Living protoplasm reduces the salt, while dead proto- plasm does not. e specific gravity of the protoplasm of Spyro- yra was increased, and was found to contain silver deposited in its interior. Argyria, or the effect of nitrate of silver on the human subject in certain diseases, was found in these alge. Thus was shown a specific chemical difference between living and dead protoplasm. Ordinary poisons, such as prussic acid and strychnine, seem to have no particular effect on lower organisms, while the poison irresistible by all protoplasm is hydroxylamyl. Professor Burdon-Sanderson said that this investigation had more ‘importance than might at first appear, for it had arisen out of the epoch-making paper of Pfliger. Pfliiger concluded that there must be a chemical change in the transition from living to dead F} 1886. } Zoology. 73 protoplasm, and Dr. Loew took up the question as to what ex- actly this change was. His investigations are an important step in deciding this important question. Professor Stirling said this gave a new test for living protoplasm. The chief thing to settle was what exactly causes reduction of the silver. SPHARULARIA IN AMERICA—In 1836 Léon Dufour described (Annales des Sciences Naturelles, ser. 2, v. 7, p. 9), a peculiar ver- miform parasite, which he found in Bombus terrestris and B. horto- rum, to which he gave the name of Spherularia bombi, placing his new genus among the entozoa. In noting the occurrence of this genus of parasites in America, it may not be out of place to give some further account of it because of its unique structure and metamorphoses, and to enable its easy recognition. Dufour’s description reads: “ Teres, albido-pellucida, mollis» filiformis, haud annulata, undique spherulis vesiculæ formibus granulata, antero posticeque obtusa subrotundata.” He adds in the French notes which accompany the above description that the length is 6-8 lines, that it is not very slim since it is about a line in diameter, that it shows no distinction of head or tail, being obtuse or rounded at both ends, and that all the surface, bot above and below, is covered with spheroidal granulations which are like subdiaphanous vesicles. ., Von Siebold, in 1838, wrote of this worm, and mentioned find- ing its young in bees, and that the young differed greatly from the supposed adult in having smooth skin, From the active young he saw that the worm belonged to the nematoids, but in the supposed adults, which were all females, he could discover no Motion. He further notices that its digestive apparatus {differs from that of all nematoids. _ Siebold and Stannius write, “One finds neither mouth nor anus in Spherularia bombi, and the intestinal canal is replaced by a Series of elongated cells, adhering together, and around which the genital organs are entwined.” The next naturalist to investigate this curious animal was Lub- bock, who published, in 1861, in the Natural History Review, a paper “ On Spherularia bombi” illustrated by a plate. Lubbock iscovered at one end of the body which Dufour had described a Minute nematoid worm, and-wrongly thought this minute worm P be the male in copulation with the large body which was the emale. In describing the so-called male, he is careful to state that he had not been able to distinguish any generative organs or any trace of spermatozoa, and discusses the possibility of the 74 General Notes. [January, two relatively enormous organs—the double series of secretory cells, and the ovary.” The double series of cells he terms the corpus adiposum, and homologizes it with the intestine of other nematoids. Lubbock mentions briefly the prolificacy of Sphzrularia, and the mode of development of its eggs. He discovered that the parasite was only present in large females of Bombus, but he was unable to trace its metamorphosis, and to discover how the bees were infected. In a later paper Lubbock gives a brief account of his further studies on Spherularia. He succeeded in keeping the young alive several weeks in water, and suggests that the young pass from moist earth into the bees while the latter are going about in moss and damp grass. He found half-grown females of Sphzru- laria, but still always with the so-called male attached, and he calls attention to the peculiar cell-structure of the so-called females. Schneider was led by the cell-structure of the so-called females, and by the organic union between them and the little worm at their end, a union at a point where the sexual opening should be, to express the opinion that the so-called female was the evagi- nated and full-grown ovary of the little worm to which it was attached. Schneider’s opinion, derived from structure, awaited proof based on observation, and this has at last been furnished by Leuckart. Leuckart, in a preliminary communication in the Zoologischer Anzeiger of this year traces the evagination of the genital organs of the female to form the appendage which was so long regarded to be the female itself, the subsequent growth of the appendage, and the origin and homological significance of its parts. This worm-like body may even lose the minute female from which it was originally an evagination even before its eggs are ripe. Lubbock, in the paper already mentioned, and Linstow, in his “ Compendium der Helminthologie,” enumerate the species of Bombus in which Spherularia bombi has been found; the former author gives their relative abundance in different species of bees, and states that the number of Sphzrulariz usually pres- ent in a single bee is from four to eight, but in one specimen he obtained no less than thirty-four, the greater number of which were full-grown. In some European species of Bombus one-half the large females which have hibernated contain these parasites in May and June. Wishing to see if Sphzrularia was to be found in America, I examined ten specimens of Bombus taken on the roth of June last, in Cambridge, Mass. The species of Bombus were not determined. Only two of the specimens were parasitized; in one was a single Spheerularia, in the other were two. The Spheeru- laria found single was 2.9 centimeters in length; each of the other specimens was a trifle shorter. Nothing seemed to indi- appren 1886. ] Zoology. 75 cate that the specimens found in the American bees were other than Spherularia bombi, except that they were a trifle larger than the size usually given for that species. Dufour states the length of S. bombi to be from “6-8 lin.” Lubbock “ nearly one inch,” and Leuckart “1.5 cm.” Further examination of females of determined species of bees, at the time when they come from their winter retreat, and more specimens are necessary to know whether Sphzerularia is as abundant here as it is in Europe, and whether the species is the same.— George Dimmock. Nores oN SOME EASTERN Iowa Swaits.—During the past sea- son I have taken several interesting species new to the vicinity of Davenport, Ia. Among them the Gundlachia meekiana Stimp., a shell not before reported from the West. The specimens are decidedly larger than Stimpson’s types, and extremely variable— some of them agreeing exactly with the description and figures of the G. stimsoniana Smith and Prime, and plainly indicating the specific identity of the two forms. As Stimpson writes, the septum in the aperture of Gundlachia seems to be formed at the end of the first season’s growth; but numbers of these limpets formed no plate, simply adding the second season’s growth on the margin of former peristome, thus making a real Ancylus with black conical cap. Lily pads seem to be their favorite station. Each limpet eating an irregular area on the under side, but never perforating the leaf. _ Numerous specimens of the Fyrgula scalariformis Wolf, unno- ticed since the publication of the original description nearly twenty years ago, were found near the mouth of Rock river, a few miles below Davenport. The validity of this species has recently been questioned by Mr. R. E. Call, who refers it to Pomatiopsts lapidaria Say! The specimens taken leave no doubt concerning the position of these tiny snails in the genus Pyrgula—unless the anatomy show greater divergence from that type than the shell. Our Rock river specimens are smaller, stouter than typical fossil scalariformis, and more compactly coiled—never exhibiting the peripheral carina on upper whorls. The shorter forms remind one of the common rhomboidal variety of Amculosa dissimilis Say. ese have been distributed by the writer to correspondents under the varietal name of P. scalariformis mississippiensis. Observations on Mississippi river Lioplax tend to confirm the opinion of the late Jas. Lewis, that the eastern and western ioplaces are especially distinct. The foot in our specimens only slightly exceeds the shell in length, while Binney’s figures (of the eastern form) represent it nearly double the length of shell. My measurements were taken while the animal was in rapid pe greatest length being then attained. — Harry A. 76 General Notes. [January, THE BATRACHIAN INTERCENTRUM.—The determination of the homologies of the segments of the vertebral centra of the rhachi- tomous and embolomerous batrachians is a question of impor- tance in the history of the evolution of the three classes of land Vertebrata, the Batrachia, the Reptilia and the Mammalia. I the European paleontologists, especially by Fritsch in his Fauna der Gaskohle der Permformation Bcehmens. I have reéxamined this question, and with the aid of new material I am able to reach further definite conclusions in the matter. he facts which I have discovered are the following : I. In the Pelycosauria the chevron bones form a continuum with the intercentrum! (hypocentrum Gaudry). itt caudal vertebrz of Eryops also (Rhachitomi), the chevron bones form a continuum with the intercentrum. therefore believe the intercentra of Clepsydrops and of Eryops to be homologous parts. ITI. In the caudal series of Cricotus? (Embolomeri) the inter- centra are as large as the centra, and except that they form a con- tinuum with the chevron bones, resemble them, and take part with them in supporting the neural arch. IV. In the dorsal region of Cricotus the neural arch loses its articulation with the intercentrum and stands exclusively on the centrum.* The serial homologies of the centra and intercentra are readily traceable in this genus throughout the column. In spite of these facts Dr. Fritsch and others regard the inter- centrum of the Rhachitomi (hypocentrum of Gaudry) as the true centrum. His reasons for this course are the following: I, In the caudal region of Sparagmites and Diplovertebron the neural arch stands on the intercentrum,’ so that it is easily mis- taken for a centrum. II. In the dorsal region in Chelydosaurus and Sphenosaurus, the neural arch stands above or on the intercentrum, while the centrum (pleurocentrum and hypocentrum pleurale) is reduced in dimensions. III. It thus results that the small hypocentrum pleurale resem- bles the intercentrum of the Reptilia and certain Mammalia, rather than the centrum, to which it truly belongs. I am of the opinion that the homological determinations of Gaudry and Fritsch, in this matter, are erroneous, and for the fol- lowing reasons: I. The neural arch being free may change its articulation from 1 Proceedings Amer. Philosoph. Soc., 1878, p. 510. 2 Loc. cit., 1880. Pal. Bulletin, No. 32, p. 1 5, Pl. nt. fig. §. 3 Loc. cit., 1878, p. 522. *Loc. cit., 1878 522, and 1884, p. 29. Dr. Fritsch has overlooked these refer- ences, and wrongly believes that the complete intercentra of Cricotus are confined. to the caudal region. 5 Fauna der Gaskohle, Bd. 11, Heft 1, Pl. 50, fig. 14, 1 5-16. 1886. | Embryology oF centrum to intercentrum and vice versa, while the chevron bones being continua, cannot do so. II. The neural arch actually does shift its position in Cricotus. In the posterior part of the caudal series it is principally on the intercentrum ; in the dorsal region it is on the centrum. From the preceding considerations I get the following impor- tant results : . The principal vertebral bodies in the Sphenosaurida! (Sphenosaurus and elydosaurus), if Fritsch’s descriptions be correct, are intercentra and not centra. I. It is probable that the true centra become extinct in the batrachian descendants of this family, so that the solid vertebrae of such Batrachia are intercentra, and not centra. III. The characters of Cricotus on the other hand point to the extinction or reduction of the intercentra as we find it in the pelycosaurian Reptilia, and point to the probability of the Embolo- meri being ancestors of the Reptilia, as I have already suggested.” IV. The Sphenosauridz (which must also include Sparagmites) are intermediate between the Rhachitomi and the Embolomeri, re- sembling rather the latter in the completion of the true centrum, but resembling the former in the incompleteness of the intercentrum. I note here that Dr. Credner? does not understand why I should have overlooked the discovery of the rhachitomous structure of Archegosaurus by Von Meyer forty years ago. I think any one who examines Von Meyer’s description and figures will find ample reason why one should not see the rhachitomous structure in them, without overstepping the bounds of scientific caution. And it is evident that European naturalists did not recognize this Structure, as they make no mention of it during those forty years, although specimens of Archegosaurus are abundant; but rather frequently referred Archegosaurusto the Labyrinthodontia, which are described as having the vertebrz undivided. I had hoped to have given before now engravings in quarto of these important forms, but the present U. S. Geological Survey having suspended my work, I am unable to do so.—Z&, D. Cope. EMBRYOLOGY.‘ THE DEVELOPMENT OF THE TOAD-FISH.—The development of the Batrachidze is not well known, as will appear from some the Statements in systemetic treatises. One author states that: The young of some or all the species fasten themselves to rocks y means of an adhesive disk, which soon disappears.” „It is the purpose of this notice to point out that the adhesive disk referred to above is of a wholly different nature and origin = that found in the lump-fishes and Gobiesocidz in which such Cope.

Ryner, Smithsonian Insti tution, Washington, D. C. 78 General Notes. [ January, a disk is formed by the confluence or coalescence of the pectoral pair of fins. The adult toad-fish burrows a cavity under one side of a sub- merged boulder, and to the solid roof of this cavity the female attaches her ova in a single layer. The eggs are very adhesive and quite large, measuring about one-fifth of an inch in diameter. Like the male cat-fish, the male toad-fish assumes charge of the adherent brood of eggs and remains by them until they are hatch- ed and subsequently become free. The egg-membrane or zona radiata is very firm, and adheres to the under surface of the stone by a discoidal area about 3"™ in diameter. The free globular pole of the egg is accordingly di- rected downwards. The germinal disk is developed at the lower pole and gradually spreads so as to enclose the vitellus from below upwards. The result is that the embryo is formed upon the lower or free pole of the egg, where it develops until it finally ruptures the egg membrane, when it may be said to have hatched, but, unlike all other types of fish-embryos known to me, the young fish does not at once drop out of the egg-membrane when the latter is ruptured. This is prevented by the adhesion of the ventral (now upper) pole of the yolk-sack to the inside of the egg-membrane just before the latter is ruptured. Just how this secondary adhe- sion of the yolk-sack is effected has not been determined, but the adhesion persists until the embryos are considerably over one-half , inch in length. In the course of the development of other parts, the yolk-sack is finally constricted horizontally round the middle below the body of the embryo, and becomes hour-glass-shape. This is due in part to the down growth of the mesoblastic somites on either side of the yolk from above; as a result of this a part of the yolk becomes intra-abdominal while a part of it remains for a time in the lower bulb of the yolk-sack and outside of the true abdominal — cavity. Eventually the whole of the yolk becomes intra-abdomi- nal; this is due in part to its further absorption and the further development of the abdominal walls of the embryo, but during all of this time, or until yolk-absorption is completed, the embryo remains adherent as described above. At this stage the embryo is so far developed that it would be recognizable as belonging to the genus Batrachus. The pectoral and pelvic fins develop as very short folds which are close together, the latter arising almost immediately behind the former. In the course of further development, the pelvic fins are suddenly translocated forwards in advance of the pectorals, and are finally brought to lie near the constriction in the yolk-sack and just above the lower bulbous portion of the latter. It will therefore be obvious to any one that neither the pectoral nor pel- vic fins have anything to do with causing the adhesion of the em- bryos, for both of these fins arise far above the point where the young fish is adherent. i 1886. | Embryology. l 79 The paired spinal nerves which pass to the pelvic fins are caused to cross those passing to the pectorals, because of the sudden translocation of the former pair of fins already alluded to. It has also been stated by authors that Batrachus possesses no lateral line. This isan error, for the writer found that the neuro- mastic grooves or furrows, which remain open for a considerable time on the heads of the larve, are continued into a lateral line system on the sides, a condition of things which is also very evi- dent in the adult, if the latter is carefully examined. There are also series of efferent pores present in the adults. The lateral neuromastic canal bifurcates in the vicinity of the shoulder-girdle and sends a dorsal branch backward below the base of the dorsal, and a ventral branch above the base of the anal. These two canals run nearly parallel along either side of the body and even extend backward upon the tail, as shown by some fine preparations of the skin of the embyro mounted by Professor Libbey, of Princeton. Another point of some interest is the fact that the entire brood of young embryos upon any one stone have their heads directed one way and toward the light, which comes in at one side of the little retreat prepared by the adults. This is very remarkable and seems to indicate that the direction whence the light comes has some influence in determining the direction in which the embry- onic axis will be formed in the blastoderm. Which in the first place caused the egg-membrane to adhere, is not Soluble in water, The yolk is peculiarly homogeneous and does not readily coag- ulate or harden in the presence of ordinary reagents, such as chromic acid, as long as the egg-membrane is intact. There are no oil-drops present and the ova are much heavier than their own volume of sea-water. The number of ova found in one brood varies considerably, but it does not seem that there are ordinarily much over two hundred laid in one place. They are dirty-yellow color and very firm to the touch, with a very narrow space be- tween the vitellus and enveloping egg-membrane. : The development of the toad-fish is peculiar, if not unique, in Presenting a prolonged fixed stage after the period of hatching or escape from the egg-membrane is over, during which all or nearly all of the yolk is absorbed. The embryo is therefore finally set — si without being encumbered by a heavy yolk, such as is met in the embryos of the salmon. Such a provision obviously has its advantages, especially since the young are also guarded by © male parent during the period of their helpless fixation. - One 80 General Notes. [ January, may frequently find recently hatched embryos, around the affixed pole of the yolk-sack of which shreds of the ruptured egg-mem- brane still adhere ; during the later stages such shreds are not usually visible. There is a decidedly heterocercal tail developed from a special tail-fold, since there is no absolutely continuous median fin-fold developed, as in many other forms. Oviposition occurs about the middle of July, in the latitude of Wood's Holl. How long it lasts has not been determined, but judging from the condition of the roes and milt of the adults at that time, it seems very probable that they do not spawn later.— John A. Ryder. PHYSIOLOGY. CONDITIONS WHICH DETERMINE COAGULATION OF THE BLOOD.— Herr Holzmann adds something to our knowledge of the con- ditions of blood-clotting. His results are summed up as follows: 1. A body called fibrinogen, belonging to the class of globulins, can be obtained from horse’s blood, and solutions of fibrinogen neither coagulate spontaneously at ordinary temperatures nor upon dilution with water. 2. Defibrinated blood, blood serum, watery extract of the albuminous coagulum formed in blood serum by the addition of alcohol, or the extract obtained from egg- albumin coagulated in the same way, the putrescent fluids ob- tained from cooked egg-albumin, and long-continued passage of oxygen, all cause typical coagulation of the solution of fibrinogen at ordinary temperatures, with the production of fibrin. 3. Fib- rin-ferment is not peculiar to the blood, but occurs among the decomposition products of albumin. 4. It is probable that fibrin is the product of the oxidation of fibrinogen. 5. When a dog is rapidly bled to death (one and a half to three hours), the last portions of blood drawn clot quicker than the first, though the amount of fibrin formed does not markedly vary. 6. Venous blood clots more slowly than arterial blood; suffocation delays coagulation. Curare, chloralhydrate, chloroform, quinine and soda carbonate, also delay the coagulation. SPECIAL PHYSIOLOGY OF THE Empryo.2— The last of the four separately issued parts of this work having now appeared, it becomes possible to speak of it asa whole. It may be said that the author has done for the physiology of the embryo what Balfour did for the morphology in his Hand-d00k. Some of the researches described here are closely connected with those on new-born children described in the author’s previous work, Die Seele des Kindes, to which he has frequently occasion to make reference. His most important general results are that mobility appears long before sensibility, and that the sense-organs and the parts of the 1 This department is edited by Professor HENRY SEWALL, of Ann Arbor, Michigan. 2 By Professor W. Preyer, Leipzig, 1885. pp. xu. 644. 1886. ] Physiology. 8I nervous system connected with them are capable of functioning before it is at all likely that in normal embryonic life they have any proper functions to perform. By “ mobility” is to be under- stood more especially the power of making spontaneous or “im- pulsive” movements. The presence of sensibility can only be proved by the existence of what is really a kind of mobility—that is, reflex mobility. When the appropriate reflex movements are obtained on stimulating the sense-organs it is inferred that the corresponding kind of sensibility is present. Reflex movements are not only later in appearing, but can also be made to disappear more easily than impulsive movements. The movements that indi- cate sensibility can be suppressed (in the artificially extracted em- bryo of the rabbit) by applying chloroform to the skin; with more difficulty by causing chloroform to be breathed. In either case the anzesthesia passes off very rapidly. It is supposed that the chloro- form in the first case acts directly, in the second case, indirectly, on the nerves of the skin; that it only secondarily affects the spinal cord, and that it does not act at all on the brain. The movement of ARE THE Musctes DEAD OR ALIVE DURING Capaveric RIGID- ITY ?— Professor Brown-Sequard has demonstrated that for several weeks after death, or as long as rigor mortis persists, the muscles of an animal undergo slow alternate contractions and fiongations. The movements were only perceptable when one Or the other set of a group of antagonistic muscles was divided, and ey eased totally when cadaveric rigidity finally passed away. i “NO. 1, g 6 ve xx.— 82 _ General Notes. [January, The movements were determined by measuring the angles through which a limb was turned, and also by obtaining ona rotating cylinder a graphic tracing representing the rate and ex- tent of the muscular change. A dog was killed on October 6th, and on the 15th one hind limb was fastened in extension and , 17th, 16°; the 22d, 12°; the 25th, 21°; the 28th, 23°; the 30th, 18°; the 31st, 20°; November 4th, 23°. The rigidity still per- sisted on November 8th when the observations were described. These movements are absolutely independent of external con- ditions, temperature, moisture, etc. In fact, in the same animal, while some of the rigid muscles are elongating, others are con- tracting and still others are at rest. Professor Brown-Sequard comesto the startling conclusion that these movements prove that the muscles in rigor mortis are not dead, but are still endowed with vital powers, but, however, are in a certain chemical condition which is antecedent and preparatory to final death.— Comptes Rendus, T. ci, p. 926. GLANDULAR AND VASO-MOTOR FIBERS OF THE CHORDA TYMPANI AND GLOSSOPHARYNGEAL NERVES.— Professor Vulpian has renewed after a new method his researches on this important and difficult subject. Curarised dogs were operated on in such a way that the cranial nerves could be stimulated by an induction current at their points of origin within the skull. The nerves were usually laid intact upon the electrodes; reflex effects failed, probably because the appropriate nerve centers were injured in the operation. M. Vulpian concludes that both the glandular and the vaso-dila- tor fibers of the chorda tympani leave the medulla with the facial but none of them come from the trigeminal nerve. It is certain, apparently, that the chorda tympani, besides its glandular and . vaso-dilator filaments, supplies to a large extent the anterior two- thirds of the tongue with sensory nerves of taste. Stimulation of the facial nerve at its origin causes an abundant flow of saliva from the sub-maxillary gland on the same side, but none from the parotid gland, and intense congestion of the an- terior two-thirds of the corresponding side of the tongue. Stim- ulation of the glossopharyngeal nerve at its foramen of exit from the skull causes congestion in the posterior third of the tongue on the same side and secretion from the corresponding parotid gland. When the trigeminal nerve is excited in the same way, no secretion is obtained, nor is there any vaso-motor change in the mucous membrane of the tongue. , The geniculate ganglion is a trophic center for the chorda : tympani, for, after intra-cranial section of the facial nerve, the fibers of the chorda contained in the latter remain intact while all the others degenerate. we 1886. | Psychology. 83 Though not bearing directly on the present subject, it is impor-. tant to observe that Vulpian has succeeded in separately stimulating near their origin both the spinal accessory and the pneumogastric nerves. Excitement of the first named alone causes arrest of the heart, while both are able to set up movements in the stomach and other organs. Stimulation of the pneumogastric seemed to have no influence upon the circulation or the secretion of the mucous membrane of the stomach.— Comptes Rendus, T. ct, p. 851. PSYCHOLOGY. THe Marertat Conpitions oF Memory.—The greatest pos- sible importance attaches to the question of the physical condi- tions of consciousness, but the investigation of it is surrounded with great difficulties. One of the most available points of ap- proach is by a study of the characteristics of memory.. Memory may be defined as tutermittent or recurrent consciousness; and it follows that whatever produces or destroys memory is also a cause of the appearance or disappearance of consciousness. I refer especially to reminiscence, or the recurrent consciousness of a previous impression, as that part of memory which gives it its importance in this connection. _ Memory is reasonably understood to be the result of an impres- sion made on a physical basis of consciousness by some stimulus. The structure of this matter is affected, so that on the recurrence of consciousness within it, the consciousness takes the form or char- acter of the modified structure it finds there. Important informa- tion as to the effects of different stimuli may therefore be gained by a consideration of their relative capacities for reproduction in the reminiscent phase of memory. On this point the following Propositions may be considered : _ there are two sources of impressions which reappear as memo- ries; those from the subject or subjective activities of the mind, and those from objects or things external to the mind. Before considering these, it is necessary to guard against confounding the recollection of the occurrence of an event, with the recollection-or reminiscence of the sensations which constituted that event. Thus € can remember that he reached some conclusion in a given dis- Cussion, but may be unable to remember the conclusion itself. € may remember that he was angry, but be quite unable to re- Produce the passion. He may remember that he had a toothache, but may be unable to reproduce the suffering itself. : ubjective stimuli are of the two classes into which all mental ee, fall, the intelligent and the emotional. Objective stimuli be- _ Ong to the pains and pleasures of all parts of the body, and to the gona general senses. To what extent are all these phases — Consciousness susceptible of reproduction in the reminiscent Part of memory? There is a kind of memory not strictly remi- — miscent, which may be well termed, recognition. The difference “ 84 General Notes. [ January, between reminiscence and recognition is this. In reminiscence the peculiar form of consciousness is actually reproduced, accord- ing to the law of associated ideas ; in recognition the recurrence of the original stimulus is necessary to arouse memory ; other- wise the sensation would not return to consciousness. The for- mer is evidently the stronger and truer form of memory, and as it answers our purpose best, and is most easily examined, I confine my attention to it for. the present. This much being understood, it appears to me that the follow- ing propositions may be maintained :- at objective impressions are less profound than subjective, the capacity for reminiscence being the index. II. That of the objective, those introduced by the special sen- .ses are more profound than those introduced by the general senses. III. That of the former, those introduced by supposed vibra- tions (sound, sight) are more profound than those produced by supposed contact of matter (taste, smell). IV. That of subjective impressions, those produced by acts of intelligence are more readily and exactly reproduced, than are those produced by the emotions. These propositions might be illustrated at great length, but for the present I content myself with the following: II. The pleasures and pains of general sensation cannot be re- produced by an act of memory. No one can reproduce any par- ticular pain for instance. It is probable that pleasures and pains which are characteristic (locality being left out of account), can be more or less recognized on their recurrence, showing that they make a real, but comparatively slight impression on the physical basis ofconsciousness. the reproduction is very imperfect; and although the reproduc- tion of visible objects is, in most people, more distinct, it is short of the reality of seeing. ` IV. Mnemonic reproduction of an emotion is not difficult, but falls short of the emotion itself, even in the most pronounced cases. Although emotions leave behind them deep impressions, they are plainly evanescent, in some persons more so than in others. Nevertheless a reproduced emotion is more distinctly like the original than is a reproduced sight. Of processes of the intelligence, those of the imagination are ` reproduced with great precision and clearness in most persons, but not more so than processes of reason. It is only in the intel- ligence that it is safe to say that the reproduction or reminiscence is identical with its original. It is true that the impression may be evanescent here also, but it is less so than in the case of am i i il ll ll 1886. | Anthropology. 85 emotion. It is only in bad mental health that association fails to revive completely a process of intelligence. It is a consequence of this fact that intelligence is more cumulative in its character than emotion, and much more so than pleasure or pain. Could we re- produce in our consciousness sights, sounds and sensations as truly as we do thoughts, we would be different beings from what we are. And were they cumulative in our consciousness in the same sense that thoughts are, we would be still more different. Thus there seems to be a relation between the nature of stimuli and their effects on consciousness, which may perhaps be formu- lated as follows: The persistence of an impression on the physical basis of consciousness is in inverse proportion to its intensity in con- sciousness. Thus the most violent and least permanent of impres- sions are molar, as in physical sensations. The intermediate are those of such special senses as are supposed to be the result of ex- - terior vibrations. The most delicate and the permanent, are those produced by the supposed extremely rapid vibrations of living brain-tissue. These create an accustomed channel of apparently greater perfection of construction than do the more violent forms of consciousness, which are therefore longer preserved, and more readily followed by new arrivals of consciousness. The reason for this is to be found in the probable fact, which is also supported y other considerations, that the more violent forms of conscious- hess destroy more tissue, while the most delicate forms destroy less, rendering rearrangement more easy. these considerations are of course applicable only to new stim- uli, which are not mere repetitions of old ones, and are especially not applicable to the secondary stimulus furnished by reminis- cence itself, in which are to be included dreams. That the mate- rials of thought are often only reminiscences is no objection to the theory here presented; for the processes, and conclusions of thought are perfectly new experiences when first performed and attained. And the precision with which intelligent thoughts are reproduced is a guarantee of their persistence, since each remi- niscence acts in some degree as a new stimulus. This is true of the simplest processes of intelligence in the lowest types of mind. € can derive some hints from these considerations, as to the oe of temporary and permanent states of consciousness.— - Cope. ANTHROPOLOGY .' : oe PLummets.—In the summer of 1884 Mr. H. W. Hen- nape Spent a portion of his vacation in Southwestern California, while there was enabled to gather some information from the yta Barbara Indians concerning the so-called stone plummets. hi cy have been called sinkers, plummets, sling-shots, bolas, spin- 'ng-weights, fetishes and sorcery-stones.

A very ingenious supplement to this theory is sug- gested by Mr. John Murdoch, to the effect that objects of this kind were primarily sinkers. and that handed down to their pres- ent owners they would become invested with great sacredness.

This can be accomplished, however, in the following simple way: Add only a trace of nitric acid to the prepared section, and leave it 12- 24 hours. The pigment dissolves slowly, and is taken up by the nuclei, and thus acts as a stain. The preparations are not beau- tiful, but are quite clear and distinct, and can be mounted without danger of disturbing the pigment. A similar proceeding (pig- ment dissolved by acetic acid) has been described by Leydig.’ The following is another mixture employed by Grenacher, as given by Carrière : Glycerine Alcohol (80 p. ee 2 Hydrochloric aci pets The preparations remain in this mixture until the pigment changes color and becomes diffuse. METHOD oF EXAMINING THE REFLEX IN THE CompouND EYE oF InsEcTts.—Lowne® recommends the substitution of a reflecting ophthalmoscope for the eye-piece of a microscope. “ By this means a bright luminous spot may be observed as a real image in the tube of the instrument. A quarter objective must be used, and the mirror of the ophthalmoscope must be strongly illumi- nated. The microscope is then focused so that a real image of the corneal facets is seen between the objective and the eye of the observer. By bringing the object-zlass gradually nearer to the insect’s eye the reflex will come into view. The reflex appears as a disk having a fiery glow, in moths, and as a bright ruby spot in the cabbage butterfly. Sometimes six spots, surrounding a central spot, are seen in the eye of the insect; perhaps these are diffraction-images. A similar appearance is seen when the eye of this insect is observed by the naked eye, except that the spots are black. * * * The reflex seen with the micro-opthalmoscope is green in Tipula, and bright yellow in the diurnal flies. Colore diffraction-fringes are usually present around the central bright spot in both these insects; but the central image is sometimes surrounded by a perfectly black ring.” “ The manner in which the luminous reflex scintilates is very suggestive of an alteration in the focal plane of the dioptric struc- tures under the control of the insect.” The color of the reflex obtained is supposed to depend on the color of the fluid contents of the “ spindle” (“ Rhabdom” of Gren- acher), while the reflex itself is due to reflection from the spindles, which, in moths, are surrounded by very close parallel tracheal vessels, which form a very perfect reflector. The reflex disappears very quickly even in diffused daylight, 1 Auge der Gliederthiere, p. 41. 2 Die Sehorgane der Thieré, p. 205, 1885. 3 Trans. Linn. Soc. Lond. Second Ser., Zoology. Vol. 11.

The disappearance of the reflex in the light is due to the contraction of the pigmented iris cells. METHOD oF ISOLATING THE DIOPTRIC LAYERS OF THE CoM- POUND Eyvr.—Gottsche’ was the first who succeeded in isolating the whole dioptric portion of the compound eye, so that the cor- neal facets and the cones could be examined zz sítu. The isola- tion of the corneal layer alone is more easily effected; this had already been accomplished by Leeuwenhoek, Baker, Brants and Gruel, who examined with the microscope the images produced by the corneal facets. Gottsche took the eye of a fly, and separated the inner wall, so that only the cornea with the optical apparatus remained. Hold- ing the cornea fast by one end, he next removed the red portion of the eye, z.¢, the retinule. These break off at the inner ends of the cones, leaving the cornea with the cones intact. The preparation is next laid on a slide with the convex side of the cornea down (there should be just glycerine enough beneath the cornea to make it adhere to the slide). A cover-glass is then placed over the preparation, with care to leave the concave upper side filled with an air-bubble. Slight pressure on the cover-glass will usually be found sufficient to create the air-bubble. If no undue’ pressure has injured the cones, the preparation is now ready for examination with the microscope. The tube of the microscope may now be placed so that the hexagonal facets are in focus, and then raised until the inner (upper) ends of the cones become visible, but not sharply focused. If any object, e.g., a Steel pen, is now held between the mirror and the preparation, a minute inverted image of the same will be seen in each facet. Grenacher thinks the contents of the cones (“ pseudocones”) wouid escape by Gottsche’s method, so that the experiment would really amount to no more than that of Leeuwenhoek, Baker, &c. Grenacher (Das Sehorgan d. Thiere, p. 148), taking the eye of acrepuscular or nocturnal moth that had been hardened in cohol, cuts off a section with a sharp knife, places it on a slide with the convex corneal surface below, and then removes the pig- ment by a careful use of nitric acid. With this preparation he repeats the experiment of Gottsche, and finds that the images fall not behind nor in the ends, but near the middle of the cones. This position of the images, at points where there are no percipient elements, is held by Grenacher to be fatal to the — view that they are seen by the insect. According to Lowne’s’ view, the retinula constitute a second refractive system which > Serves to magnify and erect the images formed within the cones, — So that the whole visual field consists of a mosaic of erect images. , Mill.

THE INTERNATIONAL GEOLOGICAL CONGRESS, at Berlin, Sept. th to Oct. 3, 1885.—The third and most important session of the International Geological Congress, which was instituted by an American committee of the A. A. A. S., at its Buffalo meeting in 1876, has just been held. The first session at Paris, in 1878, was really a pour parler which broke ground. The next session at Bologna, in 1881, accomplished something, but was especially useful in preparing for the work of the session just closed by deciding to produce a geological map of Europe on a scale of ysoo000, and entrusting its execution to one committee, while another was appointed to devise some scheme for unifying the nomenclature and, where possible, of fixing the limits of various congeries of beds which had heretofore been differently understood by different geologists. The obstacles which faced these committees will be at once under- stood from this bare statement and will modify any hasty impres- sion that, in fact, very little has been accomplished. | The two committees, or a majority of members of each, met at Foix, and at Zurich, during the four years which intervened be- tween the Congresses of Bologna and Berlin, and the action of the congress which has just ended was almost exclusively con- fined to the propositions made in the printed reports of these committees. ` Those who arrived in Berlin some days before the opening of the congress found, at the superb Bergakademie on the Invaliden 1886. ] Proceedings of Scientific Societies. 95 strasse, a bureau organized to examine the credentials of dele- gates and provide each with the necessary card and receipt for the ten marks cotisation, besides a medal in silver bearing the inscrip- tion on one side: “ Geologorum Conventus.

Saturday, close of the congress. Sunday, 9 A.M. excursion to Potsdam. Then followed announcements of the excursions to the Hartz, to Stassfurt, etc. This programme was followed in the main, only an extra session of the congress being intercalated. The usual course was to devote two hours to e discussion of the committees’ reports (2 to 4 P. M.), and the last two hours (4 to 6 P. M.) to scientific discourses of various delegates, The weather during the entire week was very disagreeable, cold and rainy. On Sunday morning after the close of the con- gress, it promised to be fair, but only to deceive the hopes of those who took part in the Potsdam excursion. The commencement of this trip was very beautiful, but towards the close it degenerated into a procession of dripping and shivering people who tried to look as if it were pleasant in order not to offend their kind hosts. The language of the congress had been decided upon as French, and this, no doubt, accounts for the greater share taken by the Swiss, Belgians, and French in the debates, than by the people of other nationalities, The Germans, for instance, who outnumbered l other nationalities taken together several times over, had only one representative who managed the language with fluency and led in debate—M. Hauchecorne, the active spirit of this con- gress. It is true that M. Neumayer retorted very effectively once to M. Lapparent, and his excellency v.

The committee of direction had made an arrangement with D. Reimer o., of Berlin, according to which this firm agreed to undertake the publication of the map at its own risk, provided the committee would guarantee them an edition of 900 copies at 100 francs a copy, and would advance them sums on account. The map is to consist of forty-nine sheets—7 in breadth and 7 in height. Each of these sheets is 48 by 53° and the whole of them together will form a chart 3.36 meters high and 3.71 meters broad. Professor Kiepert, of Berlin, is to prepare the topo- graphic base, using for the purpose all data at his disposition, both published and unpublished.

Propositions v and vi were carried without objection. ~ Sept. 30, 1885, at 2.30 P. M., the congress reassembled to take action on the report of the committee on the unification of no- menclature which was then presented by M. Dewalque. The reading of this report, which was much longer than the other, was taken up at p. 13, A. The thirteen pages of the report thus skipped had been in the main adopted at the Bologna Congress, a few minor points having been left for future adjustment. They concerned for the most part definitions of terms such as “ group,” which it was advised should be applied to the division of the highest order (e. g. secondary group, etc.); the next division should be systems (Devonian sys- tem, etc.); the third should be series (e. g. the coal measures sertes of the Carboniferous system) ; the fourth division should be stages (“étages ”) (millstone grit, stage, etc.); the division of the fifth order was decided upon for French only, “ assise” or “ couches.” Zone” should be used for a number of beds having one or more fossils to characterize them, but it should be inferior as an order of classification to “ stage.” “Bank” was selected to imply a bed (couche or assise), thicker or more coherent than those in its vi- cinity, among which it is intercalated. These and certain conclu- Sions as to the application of the terminations “ary,” “ic,” a d ian”—the first for the groups, the second for the series, and the third for*the stages—completed the linguistic portion of the report. It is to be observed that no adjective termination to pre- cede system was proposed. The remainder of the report, unacted upon, concerned subjects partly implied in the later portions. Archean—It was decided to give to the Pre-palzozoic rocks the name Archzan instead of Primitive, and while recognizing three divisions to allow each geologist to distinguish them by petro- graphic characters. _ Silurian —On the motion of Professor Archibald Geikie, the de- cision as to the limits of the Silurian and Devonian is left till the meeting of the congress in London in 1888, but the committee on the chart has liberty to divide the lower system of the Palaeozoic group into three parts of which the names will be determin upon later.

Geikie as not representing the real associations of these beds]. Carboniferous.—The question of associating the Permian with the Carboniferous provoked the most interesting discussion of the congress, Stur of Vienna, Lapparent, Blanford, and Professor New- berry spoke in favor ofsuch union. Hughes, Topley, Nikitin, anda great many others spoke against the association. Professor New- berry in the course of his remarks, said that “his honored col- league, Professor Hall, was of the opinion that the Permian did not exist in America, and that his own studies confirmed this view.” M. Neumayr thought “the decision of such questions as this should not depend upon a majority vote which would change in each country, and after each eloquent speaker (referring to M. Lapparent’s brilliant defense of the committee’s proposition). This view was finally taken, and the congress adopted, with about fiteen dissenting votes, the following proposition formulated by M. Dewalque: “The congress not wishing to pronounce an opinion on the scientific question will leave the classification as it is.” _ Triassic—After much debate the three-fold division of the Triassic was agreed to, but without giving names to the divisions. Jurassic—The division of this system into three was adopted, but without specifying the names of the divisions. It was agreed that each geologist might draw the upper hori- zon of the lias where he thought best. Cretaceous —It was agreed that the Gault should be joined to the Cretaceous. Tertiary.—-The divergence of views on this subject was so great that M. Capellini then in the chair, cut short the whole ques- tion by asking for a vote of confidence in the committee, which was unanimously given. Eruptives—Finally the seven-fold division of the eruptive rocks, in as many tints of red, was carried without opposition. This completed the serious geological work of the congress, and it was then agreed to meet in London in 1888. A committee consisting of Hughes, Geikie, Blanford and Topley was appointed to make the necessary arrangements, and the congress adjourned. During the course of the congress addresses were given by M. Gaudry on certain reptiles; Newberry, on a new large Devonian fish from America; Posepuy, on the fluid condition of the earth’s interior; Ochsenius (in German), on the origin of salt deposits; Neumayr, on the plan for the “ nomenclator palzontologicus,” which he is compiling (and which the congress voted to publish under its auspices and through the agency of a special committee consisting of MM.

THE AMERICAN NATURALIST. VoL. xx.— FEBRUARY, 1886.—No. 2. THE POST-MORTEM IMBIBITION OF POISONS. BY GEORGE B. MILLER, M.D.) HE subject is one not only of a highly interesting character to the scientific observer, but also an important one from its medico-legal aspects. Perhaps the questions which very natu- rally first arise, viz., What is its nature and what are its medico- ‘legal relations? can be best answered by the following hypo- thetical case, which it is hoped will serve to illustrate the sub- ject in a manner best calculated to aid in its thorough compre- hension. Suppose a person dies of a natural cause, and is buried in the usual manner in conformity with the established customs of his country, the body to all external appearances not having been tampered with. Also, that, after the lapse of a few weeks, an indi- vidual who had previously introduced into the body, per mouth or rectum, a poison or poisonous solution for the purpose of ac- cusing an innocent person of a horrible crime, should quietly circulate a report that the deceased had been poisoned, and inti- mate that the crime had been committed by such and such a per- son. With what remarkable lightning rapidity does a report of such a sensational character as this travel from one individual to another, rarely ever finding the doors barred, the contrary being — the tule! This report would in a short space of time reach the tribunal of | justice, cognizance would be manifested by the Proper authorities, who would order the body to be exhumed, the various organs removed and given in charge of a reliable F expert, who would subject them to a ĉhemical analysis, which 1 Inaugural thesis presented to the Faculty of the Medical Department, University -o : of Pennsylvania, A. D., 1885. VOL. atao, 11. A 102 The Post-Mortem Imbibition of Poisons. (February, would reveal the presence of the suspected poison. The subject is not of very recent date as many are led to suppose from the meagre account given, if given at all, in some of the standard text-books on toxicology of the present day. As far back as the time of Orfila, when he swayed as chief of the toxicologists, was the subject known, and indeed it appears that almost cotempora- neous with the birth of toxicology, already an account of the subject appeared. In order to see in what light the subject was regarded in former times, extracts from the writings of a few authors will be here made, as to go over them all would involve a great amount of unnecessary labor. How eloquent is the language of Orfila on the subject, and in what an exceedingly small number of words does he illustrate the whole subject (Orfila on Poisons). He writes: “ Suppose some wretch, with the design of accusing an innocent person of the crime of poisoning, should introduce into the digestive canal of a dead body a poisonous solution, which would afterwards penetrate by imbibition even to the remotest organ from which it would be subsequently extracted by the experts, and would lead them to the conclusion that they were dealing with a veritable case of poisoning.” From the fol- lowing it will be readily seen that the celebrated chemist, Sir Robert Christison, although not in possession of any evidence of crime having been practiced, yet was fully aware of the circum- stances under which it might perchance be committed. Says Christison: “ Although I have never been able to find any authentic instance of so horrible an act of ingenuity having been perpetrated, it must nevertheless be allowed to be quite possible.” The realization of the greatness of the crime does not seem to be apparent to the wretch who is meditating the commission of it, brooding over the insults of another, and holding malice against a fellow-man or especially (as it affords a better chance . for the full performance of his crime), against one of his relatives, and ravenously seeking retaliation; for if it was realized, how is it possible that an individual, capable of the perception of right and wrong, living in society, constituting a part thereof, mutually dependent on and cooperative with his neighbor, could use such means for the wicked fugtherance of his ends? That there have existed in times past among the communities of the civilized nations of the world, individuals who haye har- 1886.] The Fost-Mortem Imbtbition of Fotsons. 103 bored such hatred toward their fellow-men that they have not faltered in carrying their intentions into practice, is manifested by the defences set forth in the trials of various murder cases, which are recorded in the annals of the. tribunals of justice, not only of the New but also of the Old World. That in a number of murder cases the defence has been that the poison was designedly introduced into the dead body for the purpose of crimination is made apparent by the narration of the following cases: Professor John J. Reese, M.D., in his article on the Post-Mortem Imbibition of Poisons (Transactions of the College of Physicians and Surgeons, 1877), relates a remarkable case of alleged arsenical poisoning, which occurred in one of the Western States. The suspicions were exceedingly strong that the poison was introduced after death for various reasons, The old man having been treated in his last illness for phthisis, his physician testifying to his having died of this disease, and to his having presented no symptoms of arsenical poisoning before death The body was buried four (4) years, during which time no sus- picion of foul play appears to have been entertained. In the meantime, the widow again married, and the suspicion of poison- ing was bruited about. The woman was accused of the crime, the body was exhumed, and a chemical analysis revealed the presence of this poison in the stomach and liver. _ The defence was that the poison was designedly introduced into the body not very long before the disinterment, the body ing kept in a vault. The case, singularly enough, having had a preliminary hearing, was abandoned. Illustrative of the same, we have an article by Dr. Victor C. ag (physician and surgeon, Ann Arbor, Michigan, Aug. 883): “ During the past six months there has been tried in this B a murder case, in which the question arose whether arsen- ious oxide could diffuse after death, after it had been mixed with water, and injected into the rectum or mouth or both.” Since direct experiments by others, and by the author himself, as will be seen hereafter, seem to prove that the absorption of poisons after death does take place, it must necessarily — me an important factor how in such cases to differentiate eet from post-mortem poisoning. The methods are very limited. Perhaps the most reliable as well as the most con- 104 -= The Post-Mortem Imbibition of Poisons, [| February, clusive evidence of ante-mortem poisoning are the symptoms manifested by the patient before death. Of little less importance is the revealing of the presence of the poison by chemical analy- sis in the interior of a large organ, as for instance, the liver; since it does not appear to be likely that a poison introduced after death could penetrate by imbibition even to the interior of so large an organ. That Professor Reese attaches much importance to the detection of the poison within organs will become evident by the following extract from the article before mentioned. Says Professor Reese; “ If the poison were found on the exterior of the organs only, and not in their interior, after a careful research, I should regard it as a true case of ‘ Post-Mortem Imbibition.’” In this connection a digression may be allowable relative to the impregnation of a dead body from arsenical soil into which it is sometimes unfortunately placed. In those cases, where owing to suspicions of poisoning it becomes necessary to disinter a body for legal purposes, it is often found that the coffin in which the remains are deposited has burst open, thus allowing the contents to come in contact and mingle with the soil (which in some rare instances contains arsenic). At the trial of these cases the counsel for the defendant, hard pushed for a defence, and whose only resource lies in a choice between “insanity ” and “arsenical impregnation from the soil,” in some cases selects the latter. The actions of lawyers in setting forth such groundless defences, being cognizant of the impossibility of the transudation taking place, a and living in the light of present scientific knowledge, might be looked upon as of doubtful propriety. Unfortunately, in’ order to show that such a course is frequently pursued, it is only necessary to search the actions taken by the Commonwealth in the trial of cases of this nature, when it will be found that along with a chemical analysis of the organs, there is made also a chemical analysis of the soil. Indeed, this mode of action was taken in a recent case of arsenical poisoning occurring in this city (Philadelphia), in which the prisoner, although twice con- victed, has not as yet been sentenced, on account of the existence of some of the so-called “technicalities.” From the following opinions of certain toxicologists who have made it a study, it will be seen that it is regarded as impossible for this contamina- | tion to take place. Professor Reese (Proceedings of College of Physicians and Pq ame BES pe ener a 1886.] The Post-Mortem Imbibition of Poisons. 105 Surgeons, 1877) says: “In the few cases in which arsenic has been discovered in cemetery soils, it has invariably existed in the insoluble state generally in combination with either lime or iron. Indeed, it cannot be extracted from such soils even by boiling water, but the agency of hydrochloric acid is required to render it soluble; consequently, it is impossible that arsenic should be capable of transudation from the soil into a dead body.” This assertion is corroborated by the direct experiments of Orfila (Acad. of Med., June 29, 1847), who showed that bodies buried in arsenical earth for a period of three (3) months, did not acquire any arsenical impregnation from arsenical soil. But even admitting that it is possible for a body to become impregnated from arsenical soil, it could be easily determined in case a body contained arsenic, whether it derived the poison by contamination with earth, or whether the poison was introduced into the body; by taking two samples of earth, one from the immediate contact with the coffin, and the other from the same strata, but in an adja- cent portion of the cemetery, and subjecting both to a chemical analysis; if the analysis revealed the poison in the coffin soil, and not in the adjacent soil, then it would be evident that the soil was contaminated by the body and not the body by the soil. With a view of determining whether it is possible for a poison introduced into a dead body, to penetrate through the various organs, and be recovered by chemical analysis, a series of experi- ments were conducted. A small dog was killed, and into the stomach was introduced, by means of a flexible catheter, two ounces of water containing twenty grains of arsenious oxide. The animal was placed ina. Pine box, buried, and at the expiration of sixty days was exhumed. The following organs, viz., the stomach, liver, kid- neys, lungs, heart and brain, were then removed. On the surface of the organs were observed brownish-black spots. The organs were found to be in a remarkable state of preservation, especially the kidneys. The brain was only slightly broken down, but the dura mater was intact. A bright yellow spot of the size of a small _ Pea was observed on the urinary bladder. } € organs removed were placed in separate glass jars, and then subjected to a chemical analysis. The process employed for the recovery of the arsenic being the “Frenious and Babo” or 106 The Post-Mortem Imiibition of Poisons. (February, the hydrochloric acid and potassium-chlorate method, with the purification method of Otto. These are as follows: “ The organ is cut into small pieces, and hydrochloric acid and water added. The mass is heated to near but not quite the boiling point ona sand bath. Potassium chlorate is added, in portions, the mass being stirred continually. The chlorine evolved disintegrates the organic matter. The massis stirred and heated until all the chlo- rine is driven off, and it becomes homogeneous. The volume is kept up by adding water. Allow to cool and transfer to a moist : linen strainer, and strain until the filtrate is clear, restraining all that is turbid. The residue is washed well with water. The arsenious oxide has been oxidized by the potassium chlorate to arsenic oxide. Reduce to arsenious oxide by adding an excess of a solution of sulphurous acid gas, the excess of gas being known by the odor. The mass is evaporated to twice the volume of hydrochloric acid used; cool and filter if necessary. Thoroughly saturate while warm with a washed stream of sulphuretted hydrogen, which will throw down the arsenious oxide, organic matter, sulphur and the sulphides of other metals. Filter, wash the residue until the washings are free from chlorine. The residue is washed with a few c. c. of water containing ammonium hydrate. The sulphide of arsenic will be dissolved by the ammonia water and pass through. Evaporate to dryness in a water-bath, and add a few drops of nitric acid to destroy the organic matter; the nitric acid will also oxidize the sulphide of arsenic to arsenic oxide. Evapo- rate to dryness and repeat until the mass has a yellow color. To the dry residue add a small quantity of a solution of potassium hydrate and powdered carbonate of soda, and evaporate again. The potassium hydrate will combine with the arsenic oxide, form- ing potassium arsenate. Evaporate to dryness, and add three or four drops of concentrated sulphuric acid. Heat on naked flame until vapors of sulphuric acid cease to arise. The sulphuric acid will clear the organic matter. Pulverize the residue if necessary, add 25 c. c. of water, and one drop of sulphuric acid to acidulate. Boil and filter. The filtrate which contains arsenic oxide should be colorless. Reduce arsenic oxide to arsenious oxide by an excess of a solution of sulphurous acid. Concentrate until all of. the sulphurous acid is gone, and about 20 c. c. remain. The reagents employed in the extraction of arsenic, themselves a 1886, | The Post-Mortem Imbibition of Poisons. 107 frequently contain this substance, notably those of zinc and sul- phuric acid; hence, it becomes necessary to test all reagents to determine that they are absolutely free from this poison. None but “chemically pure” reagents were employed, the sulphuric acid being found to be such after subjecting it to Marsh’s test. On the application of Reinsch’s test to the hydrochloric acid and copper foil, they also proved to be reliable. Summary of results obtained by chemical analysis of the organs removed from dog con- taining arsenic: The extracts obtained from the stomach, liver, kidneys, lungs, heart and drazz were subjected to Reinsch’s test, and from a// of these organs arsenic was recovered. In each case a sublimate was obtained on the side of the reduction tube, which, placed under the microscope, revealed the presence of arsenic by exhibiting many beautifully formed octohedral crystals. It should be remarked that the results obtained from the examination of these organs were about equally striking, with the exception of the brain, which gave somewhat less marked reactions. On examining the literature of the subject of the “ Post- mortem imbibition of poisons,” it will become apparent that it has not received the amount of attention it so justly deserves. Indeed, so far as the writer has been able to learn the only inves- tigations pertaining to the subject are those of Drs. Victor C. Vaughn, Kedzie and George McCracken. Dr. Vaughn in the first of his experiments (physician and sur- geon, Ann Arbor, Michigan, August, 1883), used a musk-rat, injecting into the mouth and rectum by means of a syringe fifty (50) grains of arsenious acid suspended in cold water. The rat was buried twenty-five (25) days, and the organs subjected to a chemical analysis, which revealed the presence of this poison in the kidneys, liver, lungs, stomach and contents, large intestine, small intestine, heart and brain. In his second experiment a cadaver was used, an unweighed quantity of arsenious oxide was introduced into the mouth and rectum, the body being then placed in a cellar for twenty-five (25) days. The brain was broken down, and in a semi-fluid condition, the rest of the organs firm. Chemical analysis revealed the poison in the right and left kid- _ ney, liver, lower lobe of right lung, heart, rectum, spleen, stomach] Dr. Kedzie, of the Michigan Agricultural College, working inde- ae pendently » made experiments on a cat with like results. In again a 108 The Post-Mortem Imbilition of Poisons. (February, referring to the results of the experiments by the writer, it will be seen that arsenic was recovered from the drazu of the animal into which this poison had been introduced. The fact that a poison, introduced after death, can penetrate through the various tis- sues and saturate the great nerve centers, protected and sur- rounded as they are by a bony casing, must be looked upon as an astonishing as well as an interesting fact. Upon this point Dr. Reese (Transactions of College of Physicians and Surgeons, 1877), observes: “It is scarcely conceivable that a poison intro- duced into a body after death could penetrate by imbibition within the cavity of the cranium and spinal cord.” In the experiments of Dr. Vaughn, the following explanation is offered for having found arsenic in the brain, viz., “ In injecting the solution into the mouth, the syringe used clogged up, and on attempting to force it free, a portion of the fluid was observed to flow from the nostrils, some of this fluid probably adhered to the pharynx.” In the writer's experiments, when the dog employed was being placed in the box,a small amount of fluid was observed to trickle from the nostrils. Whether the presence of arsenic in the brain was due to the foregoing accident or not is uncertain. In a series of experiments on “ Post-Mortem Imbibition of Poisons,” Dr. Geo. McCracken introduced the three poisons, viz., arsenic, tartar emetic and corrosive sublimate, and subsequently recovered them by chemical analysis from several organs. ; Though always allowable, it is not our purpose to nenit to draw positive deductions from the facts adduced, but rather to allow our own results, which have been gained by a strictly scien- tific process, fo speak for themselves, In conclusion, however, it may be remarked that the hypothesis that arsenic through the process of post-mortem imbibition from the alimentary canal is, by careful chemical analysis, discoverable in the brain, receives entire confirmation from the P researches.

HIS famous volcano, called Popocatepetl from the Aztec popoca, smoking, and ¢epet/, mountain, was the objective point of my journey to the Mexican plateau. The Nevada de Toluca I had seen a few days previous from the town of Toluca, on the Mexican National Railway. This volcano, however, is not a sim- ple conical peak, but its snow-covered dome rises 15,156 feet above the sea, and out of a mountain mass with four lesser eleva- tions about it. From Toluca the crater is seen to be a very large one, and we were told that it is 1500 feet deep with a lake at the bottom said to be two and a half miles across. Orizaba we were yet to see; but nothing could, we thought, exceed in interest the distant view of Popocatepetl from the top of our hotel in the City of Mexico, as the setting sun gilded its snowy dome, and as it went down painted its snow fields with roseate hues. It is the grandest mountain summit of the valley of Anahuac. It repeats, but with emphasis, the purity of form and massiveness of Mt. Shasta, in Northern California. Its twin sister, the volcano of Iztacihuatl, or the “ snowy woman,” forms a part of the same isolated range—the Cordillera of Ahu- _ alco—and was doubtless thrown up at the same time; but it has no central dome cleaving the sky, the mountain mass extending as a range running nearly north and south, with three broken irregular snow-covered summits, of which the central is the high- est, reaching’an altitude of 4786 meters or 15,705 feet above the sea. The height of Popocatepetl has been variously estimated. Humboldt placed it at 5400 meters, or 17,716 feet; Guyot gives its altitude as 17,784 feet; Humboldt’s measurement combined with those of two later observers, is 17,853 feet, while the French savans of the Maximilian expedition put it as high as 18,362 feet. The height of the City of Mexico above the sea is 7482 feet, so that we had before us an ascent of a little over 10,000 feet. This 1S nearly 2000 feet less of an ascent than that of Mt. Shasta, which s 'S 14,442 feet high, while the plain out of which the California volcano rises is about 2000 feet above the sea. oo ee : For two days previous to starting we were occupied in arrang- ing for the ascent. Our party consisted of three. Mr. F A. 7 Ober, author of the interesting Travels in Mexico, who had pe IIO Ascent of the Volcano of Popocatepetl. (February, viously made the ascent, kindly accompanied us to the snow line as guide, interpreter and friend. We laid in supplies of boiled chicken, other meats, bread and tea for our night at the ranch and the noon lunch on the summit. By the kindness of Messrs. D. S. Spaulding & Co., I obtained a letter from General Gaspar Sanchez Ochoa, the proprietor of the mountain, to one of his employés, Sr. D. Mariano Mendizabal, at Amecameca, who was ordered to send his son Rafael to guide us to the summit. The day pre- vious to leaving the City of Mexico I telegraphed to Senior Nor- riega, a grocer at Amecameca, for horses.and guides for a party of four. That evening the sun sat clear on Popocatepetl, and the weather promised to be clear and fine on the morrow. On the morning of March togth, after an early breakfast, we drove to the' railroad station at San Lazaro, leaving it at 8 A. M. The sky was a little overcast, but soon the sun came out clear and hot. We soon crossed the edge of Lake Tescuco over a causeway, along the canals traversed by Indian dugouts, over the shallow reedy lake, in which were men and boys naked or stripped to the knees, wading through the water, fishing in its shallow depths with nets for shiners or axolotls. The track then leaves the lake and its flaggy, reedy shores and passes over a broad dry plain, the ancient bottom of Tescuco, the western portions of which are said, by Humboldt, to have been covered with water in 1521. Here were to be seen the mounds of that busy ant, Po- gonomyrmex occidentalis, so familiar a sight from Montana to New Mexico and from Kansas to Reno, Nevada. At the first station of Equipajes we get a fine view of Popo- catepetl and Iztacihuatl, The railroad then skirts the bor- ders of Lake Chalco, and we see upon our right many of the famous floating islands covered with green flags and reeds, which had survived since the time of Cortez. At the station of Ayotla the Indians crowd about the train offering fishes wrapped in the leaves of the pond lily, and here we bought half a dozen large axolotls fora centapiece. We then passed within sight of Chalco, the oldest Indian town of the valley of Anahuac. Amecameca, the town where we take our guides and horses, is about forty miles by rail from Mexico and 1274 toises or 8223 feet above the sea. Itis the highest town in Mexico; its elevation renders — 1 The two others were Professor J. W. P. Jenks, of Brown University, and Hon. ‘Titus Sheard. I i i f f 1886. | Ascent of the Volcano of Popocatepetl. III it more salubrious and cooler than Mexico, being nearly 600 feet higher than that city, and it is somewhat frequented by invalids from the city in hot weather. Before reaching the town, how- ever, we pass through foothills covered with a growth of pines and oaks, with an intermixture of maguey or century plants under cultivation. The scenery now becomes very grand as we skirt along the ranges—from four to six—which are parallel with IĪztacihuatl. At 10 A. M. both volcanic peaks were enveloped in cumulus clouds, but they rolled away from the mountain of the “white woman,” still, however, obscuring the snow-clad dome of Popocatepetl. The massive base of Iztacihuatl below the clouds was seen to be studded with conical peaks, any one of which would be a prize in Maine or New Hampshire. As the train stops at Amecameca we pass the hill of Sacramonte, covered with a dense growth of noble cedars and pines surrounding the chapel on the summit, and enter the railroad hotel at eleven o'clock for dinner, first, however, regaling ourselves with the full and superb view of Popocatepetl and its sister volcano, whose serene heights now clear and well-nigh cloudless, looked down upon the town spread out over the valley at their feet. After dinner we met our guide Rafael with his men, horses and pack mules at the grocery store of Sefior Francisco Norriega, where we laid in additional provisions, and punctually at one o'clock started for our camp at the base of the peak. Our party consisted in all of seven horsemen, with two pack mules and three mozos or guias on foot. A guia is an assistant guide, usu- ally an Indian servant or mozo. For the benefit of any one in- tending to make the ascent, I. give in a foot-note’ the particulars of our outfit of guides, servants, etc., with the prices, being a copy of the items in Rafael’s bill. 1 4 horses at $2.00 a day eneeeeneeee URS at BIOO ack vie eb eneeeneenes a 12 00 PMNS RE BECO cia voce pan seaccnens chet eee bes eens 6 00 1 barley for the horses and mules.........-++++- pasbucueuse 17s 6 pieces of leather for making sandals. .....- 7st ene ee MOO WNW re Decl os Livers t ceakee eo A ae tweed. k5 S leather thongs... csceevcs «secur t eTo nituan ni nai a aaa 50 8 yards of cloth for wrapping the feet.....-+++++++++ RO ey eee ee... evi ee Sie A mozo to look after the horses at $3.00 a day.....-.- visst 6 00 Rafael Mendizabal Josan 10 se eee eee eee 112 Ascent of the Volcano of Fopocatepetl. [February, We were urged to discard our shoes and let the guias wrap our stockinged feet in rags with a pair of rough leather sandals, but we preferred to wear over woolen stockings our ordinary high shoes and over the latter a pair of arctics, and found that they answered the purpose admirably in walking over the soft snow and yielding sand of the peak, while our feet did not suffer from the piercing cold winds of the early morning hours. We had provided ourselves at Mexico with a pair of native blankets for the bivouac at the ranch. Thick gloves are also needed, while blue-glass goggles, which most of the party bought at Norriega’s, are absolutely indispensable. It is impossible to walk over the snow fields of Popocatepetl in the glaring sunshine with- out them. I carried and tried to use a pair of colored eye- glasses, but they would slip off while walking, and proved a source of constant annoyance until my guia changed with me, — and considerately made the best use he could of my glasses. The charges of the guide Rafael were fair, but we could have dispensed with the Spanish assistant guide and the mozo to attend the horses. The gutas, or sub-guides, were Indians, nearly of quite full-blooded, and were strong, faithful young men. They expected and received besides their regular pay a gratuity for their services. Were I to make the ascent again alone, a good mozo besides the guide would be indispensable. No one should attempt to ascend the mountain alone without such attend- ance, as some accident might happen on account of the altitude, though there.is no dangerous climbing. We were gone a day and a half from Amecameca, but of course two working days were spent and charged in our bill, _ Our cavalcade passed through the dusty hot streets of the town, here and there shaded by hedges of cactus or maguey and rows of mesquite trees, the unclouded tropical sun beating upon our heads, though a cool westerly breeze somewhat refreshed us. Leaving the town the road passed through broad wheat and corn fields, and in an hour's ride from the city we left the plain and came to the edge of the foothills of the cordillera of Ahualco, the range from which rises the two volcanoes, of which Popocate- petl is the southernmost. — We were now ascending, and were for several hours to ascend the range, into the pass between the two volcanoes over the trail. made by Cortez during his march from Puebla to the City of + Ataa eee 1836.] Ascent of the Volcano of Popocatepetl. 113 Mexico. We met trains of pack mules and donkeys coming from Puebla, and it added no little zest to our ride to recall the memorable march of the Spanish conquistador from the plains of Puebla to the then famous Aztec capital of Tenochtitlan. In his Essai politique sur le Royaume de la Nouvelle-Espagne, Humboldt refers to this road or trail, which was first opened by the ancient Aztec couriers from Mexico to Puebla by way of Amecameca The plains over which we trotted were evidently an old lake bottom. The road now ascended between low rounded hills which had every appearance of moraines; they were composed of loose sand and gravel, with boulders of black basalt like that forming the volcano, and sloped gradually down to the plain. One very regular mound which we passed on our right, which rose abruptly from a corn or wheat field, seemed to have been artificial in its origin. It is Tetepetongo, “the hill of the round stones,” and according to tradition, says Ober, was for- merly used as a place of sacrifice. But the zone of moraine-like hills we were now passing over contrasted strikingly with the broad flat plains beneath us and with the ragged volcanic foothills of Iztacihuatal far above us on our left. Though this peak was capped with clouds, the larger part of the snowy dome of Popo- catepetl was in full view, and from it two glacier-like streaks of snow led down the valleys, losing themselves in the ragged lava streams at the base of the cone. As we pass onward and upward conical tumuli of loose débris from the mountains above confront us, and well-marked lateral moraines extend out upon the plain on each side of the trail. We should judge that the level at which we saw the lowest moraines was about 9000 feet above the sea; from that level they were observed up to or near the snow line, the height of which above the sea, in the latitude of the City of Mexico, Humboldt puts at 4600 meters or 15,333 eet Je were unable to see such good clear natural sections of a 1 : : A Lorsqu’au mois d'octobre de le l’année 1519, le corps d'armée des Espagnols et es Tlascaltéques marchoit de Cholula a Tenochtitlan, il traversa la Cordillére t aang, qui réunit la Sierra Nevada ou Iztacihuatl à la cime volcanique du Popo- . ‘Satepetl, Les Espagnols suivirent & peu prés le méme chemin que prend le courier Ms Mexico pour aller a la Puebla par Mecameca, et qui se trouve tracé sur la carte de miler de Tenochtitlan, L'armée couffrit à la fois au froid et de Vextreme impté- des vents qui régnent constamment sur ce plateau.—Essai politique, etc., H, 114 Ascent of the Volcano of Popocatepetl. (February, moraine as would have been desirable, but in one instance the moraine was composed of the fine mud scrapings of the lava with rounded boulders of basalt of all sizes up to four or five feet in diameter, the hill being covered with wheat and smal) corn. Moreover the hills above the moraines on each side of the valley had apparently been molded by ice. I infer from all I saw on the ascent that the ice must have filled the valley or pass between Iztacihuatl and Popocatepetl, spreading out over the plateau like a mer-de-glace and sending glaciers down to the lakes then cov- ering the plains of Anahuac. Above the rounded hills were rough volcanic spurs and hills which may once have overlooked the ice streams. It would appear, then, that the Quaternary lakes of the Mexi- can plateau (unmistakable evidences of which I saw throughout the country from Laredo to San Luis Potosi, and thence to the City of Mexico, as well as along the Mexican central route to New Mexico) were fed by the melting of glacial ice in the high sierras. At any rate in the valley of Anahuac the volcanoes rising above it must have been covered with glaciers which de- scended to a point gooo feet above the sea, and about 1000 feet above the present level of the plains. The change in vegetation as we left the plains and wound among the moraines was an interesting feature of the ride. The zone of cactus, nopal, mesquite, etc., of the Mexican plateau was replaced by a belt of pines, aromatic firs and cedars; the flowers had changed in character and become more numerous and varied than on the dry and dusty plains ; lupines predominated, relieved by a showy red labiate flower and yellow-flowered shrubs. Of 1 In conversation with Mr. Otto Finck, to whom I described the moraines about Popocatepetl, he told me that what he regarded as true glacial moraines extended down along the route of the Mexican railway as far as Peñuella, which is three miles east of Cordova, and is 2500 feet above the sea, Cordova being 2700 feet elevation. I had seen boulders of porphyry above the city of Orizaba, and Mr. Finck, who is an observer of long experience in the State of Vera Cruz, having explored the country for hundreds of miles on foot, and being a naturalist of experience, kindly ‘took me down to the bed of the river, where were boulders of different kinds of hyry, evidently derived from the plateau above and westward. On the plains of Jaumatlan and Chocaman, he told me, are boulders of porphyry, weighing 200 . tons, and also glacial scratches. Mr. Finck drew for me a section of what he re _ garded as a moraine observed at the Pass of Metlac, in which were angular blocks of porphyry of ten or twelve kinds, with gneiss, which must have been transported from the plateau above. Below an elevation of 2500 feet Mr. Finck had not in thë State of Vera Cruz, or elsewhere in Mexico, observed any glacial marks. al E 1886. } Ascent of the Volcano of Popocatepetl. 115 deciduous trees, willows abounded, but few if any oaks. Through these forests, not very dense or continuous, pumas and wolves were said to roam. The insect life of the plains is scanty in the dry season, but in this zone bees and butterflies of different spe- cies visited the flowers. The zone of pines and willows was suc- ceeded by a belt of tall coniferous trees like a spruce with a fir- like habit; their slender shafts two to three feet in diameter (in one case of a tree felled with the ax, five feet) pierced the clear sky over perhaps 125 feet. This noble tree had very broad leaves and a deep red bark, like the red woods around the base of Mt. Shasta. This zone of red wood was succeeded by a belt of low short-leaved pines which grew shorter and more stunted until at half-past four we came to banks of snow lying on the summit of the grassy pass, the remnants of larger fields which had but lately disappeared. The air was now cool and even chilly, the ground was damp and often wet; here it was early spring, like our first of April in New England, too early for flowers; scattered plants, perhaps Alpine but quite unlike any we have seen in the Rocky mountains, were not yet in flower, and to add to the resemblance to a northern spring a flock of veritable robins flew among the pines ; they were lingering on the flanks of Popocatepetl before taking their final flight northward. The path to the ranch now left the Puebla trail and led us among the pines to the sheds where we were to spend the night. The rancho was reached at 5.40, and an hour still remaining be- fore dark, I walked to a ravine over piles of volcanic ash and lapilli to entomologize under fallen pine logs and the bark of stumps, finding lizards, beetles, spiders and myriopods quite unlike any forms yet seen in the zerra templada below, but with no trace of Alpine characters. The ranch was a deserted shed and furnace-house for roasting the crude sulphur formerly collected by the vo/caneros or peons at the bottom of the crater. Darkness gathered early about the ranch, but in the bright moonlight the massive, marble-like dome of Popocatepetl rose rectly above us. Our horses and mules were left to stand in the open air while we bivouacked in the shed, in the center of Which was a raised circular fireplace on which our guias made a fire of sticks and logs, the smoke and sparks passing up through a hole left in the middle of the roof. The Indians boiled their A 116 Ascent of the Volcano of Popocatepetl. [ February, coffee in their glazed earthen jars, which in the long run with- stand the heat of the fire better than a tin coffee-pot; they made tea for the party in other vessels of domestic manufacture; they refreshed themselves on cold tortillas and chili, the twin compo- nents of a Mexican meal, and then cut out their sandals for the morning’s climb, while we dismembered a cold broiled fowl of pro- nounced toughness and ate it with excellent native bread and tea. To the tourists and head-guides was assigned a sort of low raised divan or floor covered with hay, over which we spread the straw petates or pallets, and finally a blanket, with a second blanket and a coat over us. The gutas and muleteer lay on the mud floor, their feet to the fire; their swarthy faces and limbs not visible in the gloom, their white cotton garments concealed by their high- colored serapes or blankets. They slept soundly through the night, but not the tourists; the beds were uneven, an occasional flea danced a jig on our hands and faces, a rain and hail storm with a strong gale of wind rattled about the ranch; towards morning it grew very cold and chilly ; added to this two of our number, owing probably to the altitude, were unfortunately seized with vomiting aad diarrhcea, so that there was little or no sleep for the Americanos that night. At 3.40 A. M. of the 20th I awoke the party, the guias replen- ished the fire, prepared the coffee and tea, saddled the uneasy horses now shivering in the cold frosty morning air, and at 5.30 we had mounted our steeds and were under way for the peak. It was a bright, crisp, clear, cold morning, the stars still shining brightly, while a piercing cold wind swept down the valley over the pass. Our guides had wrapped their legs in thick layers of cotton rags, wound their serages tightly about them, and we found that our overcoats and gloves were but a slight protection against the intense cold. For two hours we slowly crept up by a zigzag trail, urging on our unwilling nags over the slope of the mountain ; first passing through the pine woods, then descending a barranca or ravine, through which ran a stream fed by the snows of the peak. The trail then wound along the base of the cone over fields of loose, deep, coarse, black, volcanic sand, through which rose scattered jagged masses of black lava. Our faltering horses and- not over enthusiastic guides toiled up- ward and onward, until at 7.30 we reached La Cruz, a rock on _ which was a wooden cross, where we were to leave our horses rice fi erate 1886.] ` Ascent of thé Volcano of Popocatepetl. 117 and begin the ascent on foot. Here, owing to sickness induced by the altitude, my companions were obliged to return to the ranch. Taking Rafael and two gutas I went on. The ascent of Popocatepetl is prosaic in the extreme. Much to my surprise there were no rocks to clamber over, no difficult climbing, but an interminable steeply inclined desert of deep, coarse, yielding, volcanic sand, covered with a thin sheet of snow —névé+making it exceedingly hard walking, to say nothing of the effect of the great altitude upon the heart. The height of the lower level of the snow-line Humboldt estimated at 15,300 feet. The cone of Popocatepetl is like that of Vesuvius—only more so. We roughly estimated the angle of the slope at 30°, but judging by our feelings after two or three hours’ climb, it seemed like 75°. There is no definite trail up the mountain, and at no point on the route can the summit or mouth of the crater be seen, so that there is no goal in sight to draw one’s attention away from the labor and fatigue of the ascent. Looking up hopelessly from time to time as we stop to get breath, anxiously trusting to ob- tain a glimpse of a rocky peak breaking through the crust, noth- ing meets the eye but a vast snowy slope melting away far aloft in the sky, the unsullied surface like polished marble of more than parian purity, fading gradually away to be replaced by the ee fathomless azure of a Mexican sky. By eight o'clock the sun had gained more power, the exercise warmed us, so that we no longer suffered with the cold, but the effect of the intense sunlight upon the eyes was blinding and painful; it would have been well-nigh opon to have made the ascent without blue goggles. Our small procession moved in the following order: my own particular gxia, a young, stout, willing Indian picked out a way over the rough snow or sand, as the case might be, the- writer followed, planting his feet in the prints made by the Indian, and Supporting himself with a rude, improvised alpenstock, usually held in both hands; behind followed the supernumerary gua, carrying the lunch Haake on his back, while Rafael brought up the rear, with the air of one fulfilling a contract rather than enjoy- ing the ascent. And it was hard work. I have ascended Pike's peak three times, walked up Gray’s peak twice, have climbed the crater of Mt. Shasta, which is over 12,000 feet high, ascended VOL. DORE 9 118 Ascent of the Volcano of Popocatepetl. | ¥ebruary, Vesuvius and Snowdon, and not a few peaks in the White mount- ains, the ‘Adirondacks and Northern Maine, but the labor of the ascent of Popocatepetl, owing to the far greater altitude and the consequent rarity of the atmosphere, as well as the yielding sand and the nature of the snow is peculiarly difficult. _ To my surprise the snow lay on Popocatepetl as a thin sheet of from a foot or. two to six or eight feet thick—deeper of course in the ravines, but the ravines were of a mild type. The ascent is made from the northerly and westerly side; the deepest ravine was filled with snow passing beneath into ice, thus forming an in- cipient glacier perhaps nearly a mile in length. Looking at it the day previous, from the road. below, I supposed it to be a true glacier filling the ravine, but it can scarcely be regarded as such, whatever may have been its dimensions in early times. The surface of the snow fields over which we walked was ex- © ceeding rough. The snow was, on the average, about three feet deep, cut up by deep narrow fissures lying at various angles to our line of march; the footing was thus very rough and uncer- tain; the snow grew softer as the sun rose higher, and it was impossible at times to prevent: slipping and falling down. Four _hours.of such work to one not hardened to mountain climbing at such an altitude, reaching nearly or, quite 18,000 feet, are no child’s play. One advances three or four steps, and-thoroughly exhausted sinks down upon his staff to rest and recover his breath; his heart beats-in a wild extravagant fashion, and his breathing is short, quick and labored. No one should attempt the ascent who has; not a healthy heart and sound mige and is not. under. fifty. _ | There i is danger of over-fatigue. s At about half-past ten the summit seeming no nearer ‘ian at the start from La Cruz, I asked Rafael how long it would take to ‘reach the top.

Pre ak eae ete pe PLATE VI. Summit of Popocatepetl, just within the north-west edge ¿ot gthe crater. 1886, ] Ascent of the Volcano of Popocatepetl. 119 The transition was thrilling. Here we were on the summit of the highest mountain between Mt. St. Elias in Alaska, and Chim- borazo in Peru! The sky was well-nigh cloudless, a few cottony masses hung over Iztacihuatl to the north of us, partly obscuring its peaks; the plains of Anahuac and the Puebla valley bathed in the sunlight, and wrapped in a warm, soft haze, stretched for hun- dreds of miles away west and east; the volcano of Malinche to the north-east seemed like a pigmy cone; the city of Puebla could be distinguished, but Cholula and its pyramid, which lay nearer, were lost in the haze; we could not detect the city of Mexico and its adjoining lakes, nor could I make out the volcano of Orizaba, which lay to the eastward 150 miles. But our interest centered in the crater. In comparison with that of Vesuvius or Mt. Shasta it was, it must be confessed, tame. Many have looked down into the crater of Vesuvius; that of Mt. Shasta is a funnel-shaped chasm over a thousand feet in depth, the snow fields extending from the rim to the bottom, in which lies a frozen lake. The view into it was memorable. Descending a few feet to a rock overhanging the chasm now before us, we could take in the entire basin. It seemed to us to be about 500 feet deep and from 1000 to 1500 feet across at the mouth, but according to Gen. Ochoa’s measurements it is a thou- sand feet deep, and the floor is 200 meters in circumference. It 1S Not an irregular chasm like that of Vesuvius, but like a vast cauldron in shape, the steep sides visible all around, and the bot- tom broad and somewhat flat, with no large, deep fissures visible. n. Ochoa told Mr. Ober that there are more than sixty sol- paras or smoking vents in the crater, one of them over fifty feet in circumference ; he called the vents respiradores. The northerly rim is of loose volcanic sand which has been blown up out of the crater. Perhaps two-thirds of the rim was of Solid lava more or less jagged and irregular, the highest por- tion on the south-east side. Looking across from the northerly Side one is confronted by three well-marked layers of vertically columnar basalt marking three successive overflows, while a less regular fourth layer indicated an additional eruption. The rock composing the sides of the crater, the mountain itself and the sand lying on its flanks is a tough, black basalt, slightly por- Phyritic. 3 ear the rim of the crater on the west side is a sulphur fuma- 120 Ascent of the Volcano of Popocatepetl. [ February, role or respirador, a fissure from which issued clouds of sulphur fumes, At the bottom of the crater were plainly seen two large sulphur vents or solfataras, with smaller ones from which clouds of vapor rose perhaps to a height of over a hundred feet, but cer- tainly not half way up to the edge or top of the peak. -Whether these fumes can be seen from below, at the base of the mountain, is a question. Some still claim that the mountain smokes, and that the smoke can be seen from below, but this is doubted. The assertion was made in the time of Cortez. Humboldt says: “Ce volcan, que j'ai mesuré le premier, est constamment enflammé, mais depuis plusiers siécles ow ne voit sortir de son cratère que de la fumée et des cendres,”! It is not imposs ble that the slight amount of sulphurous vapor which is emitt 1 from the crater may at times increase and be visible at night by moonlight from the plains below, or even in the daytime during certain: states of the atmosphere. I well remember that in May, 1872,4 month after the great eruption of Vesuvius, no smoke was seen to rise from the crater by day, but by moonlight, at Naples, 1 could de- tect a slight column of vapor hanging over. the summit of the cone. The sulphur vents were surrounded with mes of bright yel- low sulphur.: Near where we stood were twe or three stumps of posts which had been driven, into the volcan: . sand and gravel to _ support a windlass or winch, by. which the volcaneros were let down into the bottom of.the crater to gath- © the sulphur there. It was borne in sacks on the backs of Indi. .. “down to the ranch or sheds where we spent the night, and there ublimed in earthen pots. The crater was not measured until -856, when General Ochoa estimated its depth and circumference We roughly guessed that its depth was about 500 feet, but d stances, looking down into a mountain, are very deceptive. i appears that in the time of Cortez a Spaniard ‘descended the crater, tied toa rope, to the depth of from seventy, to eighty fathoms or 420 | to 480 feet? g \ afsagt prae sur le Royaume: dela Nouvelle-Espaghe, Toni, IF; P. 338) E ae Ow voit, a la troisiénie | et Ja quatriéme lettres de Cortez à Pempereur, que ce général ‘apres la prise ide Mexic xico, fit. fairé d’autres te ative’ pour! ‘reconnoitre la cime du-volcan, qui;paroissoit fixer d'autant plus son’a .ention, me les-indigénes lui assuroient quit mw étoit permis aucune mortel de Sapprocher. de e site des mauvais esprits. “Aprés deux essais infructeux, les Espagnols Sas tas enfin; année 1522, à voir le cratère du Popocatepetl ; il leur parut avoir trois quarts de lieue de circon- — ét ils trouvérent Sur les bords du précipice un peu de soufre qui ‘avoit été PLATE VII, A war A irr a K

February, Here in passing I may remark that Orizaba is now said to be slightly higher than Popocatepetl, though Humboldt claimed that the latter was 600 meters higher than any other mountain from Mt. St. Elias to the Isthmus of Panama. Mr. A. H. Keene, in the Encyclopedia Britannica, gives the height as 17,176 feet. I obtained excellent views of this noble volcano at different points along the Mexican railway to Cordova. Seen from the west the snow fields stretched in glacier-like streaks down its slopes; at the station of Esperanza, however, the clouds parted so that the summit could be seen from the south, and it was observed that the dark streaks of sand or rock extended in broken patches to the very summit. Orizaba rather disappointed me from this point; it is far less imposing and majestic a peak than Popocatepetl; it is not so isolated, its great height being apparently lessened by the high mountains of the Sierra Nigra extending from it towards the railroad. Moreover its summit is broken up into subordinate peaks. Farther on near where the railroad descends into the great arranca or ravine west of the town of Orizaba, the volcano of that name is seen to be of solid lava, furrowed by deep ravines; while Popocatepetl is more like a vast conical heap of ashes. Never, however, shall I forget the magnificent view of Orizaba which I had from under the coffee trees and bananas of Cordova. It was eleven o’clock in the morning, the clouds had lifted and rolled away from the mountain, which rose in a magnificent con- ical mass far above its humbler fellows of the Sierra Nigra. From the illustrations given by Humboldt I imagine that the finest view of this imposing peak is from the forest of Xalapa, to the north-east. This volcano is said to have been quiet since 1566." 1 Mr. Hugo Finck of Cordova, who has explored the base of Orizaba, told me that the crater is one and a-half miles long and a half mile wide, but that it cannot entered. He saw Orizaba smokin ng, osaa the gases from the solfataras, and stated that the mountain had erupted near the base, where there are small craters. - He has'seen a glacier near the sum elage and there are aani soe slide down and melt ponies the summit above being bare, with no D h It bable that there are at the base of Oriz ag ern rocks, as Mr. Finck yer me that gneiss gccurs as far up the sides of thie mountain as 13,000—14,000 feet, while higher up the mountain is composed of a e) rphy T apa the cen- ter of the Sierra Nigra and the mountains southward betw n Esperanza and Oriza ba, are Silurian, Devonian, and niferous strata uh: a feetid lack lim open netordell by bluish Jurassic limestones containing fossil fishes, oysters, belemnites and ferns.

At twelve o’clock we began the descent, and it reminded me strongly of the twenty minutes’ descent or run down Vesuvius. After zigzagging down over the snow and ice, now quite yielding, stopping frequently to rest one’s tired knee-joints, on reaching the sand below the snow fields, my two guias each took one of my arms and we ran down the long sandy slope arm-in-arm. We reached La Cruz by about two o’clock, and walking on a mile or so more down the slope, I found a horse which Mr. Ober had sent me, in waiting. Reaching the ranch at about three, after half an hour’s rest and refreshment, Mr. Ober and myself rode with our guide Rafael fifteen miles to Amecameca, while our guias trotted the whole distance on foot behind their pack mules. Nothing is more monotonous in its flatness than a Mexican bedstead, while the mattress is only thicker than a Mexican blan- ket, the bed being but a little more yielding than the soft side of a pine board, but that night—spent in a second-class Mexican hostelry, after such a long day’s work with the, alpenstock and in the saddle, half frozen in the morning on the mountain side and half roasted in the hot mountain gorges and on the dusty plains in the afternoon,—that night was given without reservation to the worship of Morpheus. The next day at ten we reached the site of ancient Tenochtitlan, rested in the grand plaza under the shade of the orange and banana, by the plashing fountain, our eyes feasting on the varied, ever-changing pictures of Indian, Mestijo and Spanish types of Mexican life passing before us in that famous square. NOTES ON THE CECODOMAS, OR LEAF-CUTTING ANTS, OF TRINIDAD. BY C. BRENT. N opportunity was afforded me during the winter of 1884-5 ® for studying the life and habits of this most interesting spe- cies on the Island of Trinidad, West Indies. Several species are here distinguished ; all, however, are alike in form and habit, the variety being produced by variation in size and color. These Insects are extremely numerous, indeed one cannot take a walk anywhere in the country without observing broad columns of 124 Notes on the Leaf-cutting Ants of Trinidad. (February, seemingly animated leaves marching across the roads. Com- plaints are heard on every hand of their ravages among the gar- dens and plantations. Agriculture is all but hopeless in sections infested by these pests, since although they occasionally attack one of the forest trees, they show a decided preference for the leaves of cultivated trees and garden plants, the cocoa, coffee and orange being particularly subject to their destructive visits. They seem also to develop a “penchant” for particular trees. One orange tree in a grove of the same species is stripped again and again, while the neighboring trees are left untouched. The curious habit these ants possess of cutting and carrying off im- mense quantities of leaves, has often been noted in books on natural history, although the question is still an open one as to the object of the custom and the disposal of the cut leaves. My own observations on these points I shall give farther on. The speed with which these little workers operate is indeed marvelous. A good sized mango tree, at least as large as an average apple tree, I saw stripped of every leaf in one night, and greater feats than this are recorded of these “ Tourmi Ciseaux,” as they are called by the Creoles. In the morning the naked boughs bore only the bare midrib of the leaves with here and there jagged portions of the parenchyma left by the circular pieces snipped off. The ground was littered with circular pieces of leaves about the size of a ten-cent piece, which the ants had neglected to carry off. Old leaves and young had alike been snipped off, but most of the pieces left were cut from the older leaves. During the day I discovered the formicarium to which these ants belonged, some three or four hundred yards up the mount- ain side. It was situated on a gently sloping incline covered by a dense “ vastrajo,” or second-growth wood. The site of the hill had been well chosen in a spot free from large trees, and the smaller bushes had been removed, leaving the soil as bare as if _ 7 the vegetation had been destroyed by a fire. The mound was of immense size, being about forty-five feet across and about two feet high. The soil was of a different color from that of the sur- rounding hillside, and consisted, I found, of clayey granules brought up by the ants from the subsoil below. No signs of ants were visible, nor were any recently used entrances to be seen. Several tunnels extended a short distance into the mound, but aia ney mena onc ” 1886. ] Notes on the Leaf-cutting Ants of Trinidad. 125 they were all stopped up by soil washed into them by the delug- ing rains that had been falling for several previous days. Cut- ting my way through the bushes by means of that useful and indispensable part of a forester’s outfit for tropical woods, the “machete” or cutlass, I found, some twenty yards up the hillside, an entrance from which led, as far as the eye could see, a wide smooth path, worn by repeated travel some five inches deep, and carefully cleaned of all vegetation, dead leaves and rubbish. A few yards from the entrance a huge tree had fallen but recently across the pathway, but the industrious insects had dug a tunnel six inches in diameter under it in preference to climbing over it or making a new path around it. A little farther on I met another instance of formic ingenuity. The path led to the edge Fic. 1.—An Cicodoma formicarium. The cleared space is forty-five feet in diameter, ‘ of a ravine where it branched; one branch led directly across the ravine, down the precipitous sides of which an oblique path had been excavated at an angle of about 45°; the other branch led up the edge of the ravine some twenty yards to a fallen tree which spanned it. Over this the pathway led to the opposite bank, down which it ran to join the direct path below. I subse- quently noted that during the rainy season when the ravine held a stream of water, the ants toiled up the hillside to their bridge, but, as soon as the water dried up they used the nearer path directly across the ravine. On looking around the mound I found five other entrances to the formicarium, all at some distance : from it, and from each of these diverged a pathway through the Woods. Along one of these traveled a dense column of ants, those 126 Notes on the Leaf-cutting Ants of Trinidad. (February, outward bound keeping the right hand side, while those return- ing home traveled along the left. The incoming ants were nearly all laden with their leafy burdens which they carried tightly gripped between their mandibles, sometimes nearly upright, or thrown back so as to completely hide the insect below. This curious fashion of carrying the leaves has earned for them the common English name of “ parasol” or “ umbrella ants.” Along the path were several heaps of leaves, which were prob- ably carried away by a fresh relay of workers ; often these heaps may be noticed lying deserted along the pathways, but they are invariably removed, sooner or later, to the nest. The leaves Fic. 2.—Ants at work leaf-cutting. were those of the cocoa, so I traced the column down the hill- side some four hundred yards to the edge of a cocoa plantation, _where I found them actively engaged in leaf-cutting. The smaller trees were swarming with the little depredators, leaves were fall- ing plentifully as the little sawyers snipped them out. Numbers of ants marched up the tree and numbers marched down, very deftly managing their awkward-looking burdens. Sometimes they progressed sidelong down the tree, sometimes backwards, _ according to the condition of the surface over which they walked .

To prevent the section falling she does not saw it all round, but when nearly severed seizes it by the edge and by a sharp upward jerk detaches it.

The thorax is very sharply constricted 'in the middle, the fore part, or prothorax, carrying the first pair of legs and a pair of spines upon the dorsal surface. The hinder part, or meso-metathorax, carries the other pairs of legs and two pairs of- spines. The cutting instruments are a pair of long extremely sharp-pointed mandibles finely serrated upon their inner surface, which may be used as saws or nippers. The workers vary ex- tremely in size; individuals are met with only three-sixteenths of an inch in length, while others attain a length of nine-sixteenths. These smaller (younger) ants accofpany their older sisters in their expeditions but rarely carry leaves. They may often be seen riding upon the burdens of their older and larger sisters as if tired. I have observed as many as three clinging to a leaf which was carried with apparent ease by one of the larger ants. A number of these little ants may be observed to issue from the mines with the old ones and loiter around the entrances as if as yet unable to take part with the stronger ants. Here and there among the mass of workers, perhaps forming about one per cent of the total number, may be seen a much larger, formidable-looking ant with enormously swollen triangu- lar head, which takes no part in the work, but always accom- panies the “ worker minors,” as they are called, on their expedi- tions. I spent much time trying to find out the functions of these large-headed ants, but failed to get any clear notions as to the part they play in the politics of the commonwealth. They may nearly always be seen on a bit of stick or other eminence, caress- ing now and then the antennz of the passing ants with their own. Talking, we may suppose, in ant language, since it is well estab- lished that ants are, by means of their antenne, able to commu- nicate their ideas gne to another. It appears to me that these apparently useless ants directed in some way or other the move- ments of their working sisters. Bates in his Naturalist on the Amazons, came at first to the same conclusion, but afterwards abandoned this idea for one I think not more tenable, namely, that these ants by their superior size draw upon themselves the attacks of ant-eating birds, &c., being thus, as he terms it, merely “ pieces de resistance,” thus only serving to preserve the main body of workers by a self-sacrifice of mere “ passive” resis- tance. ; went to the trouble to shoot several ant thrushes and Den- a ema aa eee 1886. Notes on the Leaf-cutting Ants of Trinidad. 120 drocolaptes which feed almost entirely upon ants, to see if there was any foundation for this theory, but found very few indeed of the so-called “ worker majors,” although the crops were distended with “ worker minors.” In other works on natural history they are termed “ warriors,” but they by no means correspond to the warrior or soldier class in the Termites, for instance. They have no special offensive or defensive weapons, their movements are more sluggish even than those of the smaller ants, and when the nest is disturbed by poking it with a stick, the smaller ants only prove pugnacious. In the battles which so often occur between the mail-clad bandits of Trinidad forests, the savage “ Ecitons,” or “ hunting ants ” and the “ parasol ants,” the brunt of the fight is borne by the “worker minors” who always drive off the marauding Ecitons. In some CEcodomas there is a series of intermediate forms be- tween the working minors and the working majors, and in some species all take part in leaf-cutting. Besides these workers there are two other classes, which never leave the mines, the worker _ nurses, to be distinguished from the working minors chiefly by their hairy heads, and another class of very large ants, individ- uals of which are found nearly an inch in length. This class is represented in each formicarium by only a few individuals, which are distinguished by their large hairy heads and the possession of a twin ocellus placed in the middle of the forehead. These never leave the mines, and are seen only when the formicarium is opened. The ant hill referred to above being a pest to the neighboring plantations, it was determined to destroy it. Poisons were found useless. Corrosive sublimate and potassium cyanide were mixed with farina and deposited near the nest. These were simply ignored; the ants would not touch them after a few had fallen victims. A solution of arseniate of soda was next sprinkled upon orange leaves, which were strewed upon the mound. These were eventually cleared away, although at an immense sacrifice of life. This points, I think, to the true ant food, since unless the juices of the leaves as they were sawed up were swallowed, the poison would have had no effect. This idea is strengthened by the fact that fiery and strongly aromatic plants as well as those with poisonous, milky juices are carefully avoided. No Solid food is found in the crops of the insect at any time, but if 130 Notes on the Leaf-cutting Ants of Trinidad. (February, these are examined after the insects have been engaged in leaf- cutting, they are found full of green leaf juice. Finally we de- stroyed the nest by drowning, the common method during the wet season. A number of channels were dug in the hillside, all constructed to collect the rainwater as it streamed down the hill, and to pour it into the nest by one of the entrances. I visited the nest during the next rain to see how the plan was working, and was surprised to find the water pouring out of an orifice twenty yards below the nest. After the rain I examined this tunnel and found that it entered the nest at the lowest point, some eight feet below the surface. I examined many formicaria subse- quently, and invariably found this lower tunnel wherever the in- clination permitted its construction. I have no doubt that it is constructed as a drain, and that the ants know as much about the advantage of thorough drainage as they have been proved to know, by many eminent observers, of those of other sanitary matters.

The natives firmly believe that the “ serpent a deux tetes,” as they call it, is the mother of the ants, and that they procure the leaves for the purpose of feeding it. The larvæ were imbedded in a soft woolly matter which proved to be the finely masticated parenchyma of the leaves. Thus a use was found for the leaves, although it reflects seriously upon the supposed sagacity of the ants that they should procure so many more than are required for the purpose. Bates states that the leaves are also used for thatching the domes over the en- trances to the mines, but I have not observed this practice in con- nection with the Trinidad species. The larvæ are fed by juices secreted by the nurses. A part of the larve emerge from the eggs winged and ready for their nuptial flight. These are the males and females, and the swarming occurs during the wet sea- son. The female measures an inch in length and two inches in expanse of wing. The wings are clear, transparent and coarsely veined. The winged males and females emerge from the woods in clouds during the rains of April and May. These are almost all destroyed by the flycatchers,. jackamars, ant-thrushes, &c., which greedily devour them; only a tew impregnated females sur- vive the slaughter to found new colonies and propagate their race. The colony is sustained, I suppose, as in other species, by the seizure and -detention of impregnated females by their own subjects, After impregnation the female loses her wings, these being broken off by the insect itself. There may be noticed a natural suture at the base of the wing, doubtless that this may be easily broken off when no longer required. THE TEREDO, OR SHIPWORM. BY R. E. C. STEARNS. ; r ERE are several species of what are popularly called “ shi worms” which are ordinarily included under the name Teredo. Although to the common observer they have a worm- like appearance, they are not worms, but true shell-bearing mol- lusks, as much so as the common “ long clam,” “long-necked - clam” or “mananose” (Mya arenaria) of the Atlantic coast of the United States, So much has been written in relation to the shipworms that it 132 The Teredo, or Shipworm. [February, would be nearly impossible to write anything that would not bea repetition or quotation. The shipworms (Teredo) were known to the ancients, and Theophrastus, the friend and successor of Aristotle in the lyceum at Athens, observed their operations 350 B. C. The late Dr. J. Gwyn Jeffreys, in his excellent volumes on the mollusks of Great Britain, presents in a very concise and inter- esting way what is in fact a most valuable memoir on the ship- worm, Teredinide. The shipworms are diva/ves, that is to say, the complete shell is in two pieces, although one can form no idea of the Teredo from them, as the shelly part is but an insignificant portion of the entire animal, as you will learn from the following: “The Teredo * * * consists of along and nearly gelat: inous, worm-like body, without rings or segments, terminating at one end ina pairof * * * valves that somewhat resem- ble the two halves of a split nutshell which has had a large slice cut off at each side, and at the other ina pair of symmetrical shelly paddles with handles of different lengths, which close this extremity at the will of the animal. The open part of the bivalve shell is placed at the further end, and receives a circular disk of a fleshy or rather muscular nature, which may be termed the foot ; this is the broadest and widest part. Inside each valve . is seen a curved process, like a bill-hook, that projects from the hinge at a right angle. The shell covers and protects the mouth, palps, liver and other delicate organs. The body tapers gradu- ally to the outer or nearer end, where it becomes quite small and attenuated ; it contains the gullet, intestine and gills, which form at the outward point two cylindrical tubes, mostly of unequal length. The larger tube takes in infusoria or similar animal- cules, which constitute the food of the Teredo, as well as imbibes water charged with air for the purpose of respiration and keeping the whole fabric moist, while the smaller tube is em- ployed in the ejection of the water which has been exhausted or deprived of aeriferous qualities, and also serves to get rid of the woody pulp that is excavated by the Teredo. Both tubes form a kind of hydraulic machine. At the base of each lies one of the paddles often termed ‘pallets.’ * * * “When the Teredo is alarmed, or not feeding, it withdraws its tubes into the neck of its sheath or shelly cylinder; and the pal- lets which had been previously kept pressed against the sides, then spring forward and close the opening so as to form an effica- cious barrier against all foes,” etc. 1 British Conchology, Vol. 111, pp. 122-184.

These burrows vary from one quarter of an inch or less to half an inch or more in diameter. It is only in its very earliest stages that the Teredo is a free moving animal. At this time no one other than a practiced nat- uralist would be likely to recognize it. “It is very minute, nearly spherical, and covered with cilia or hair-like projections, by means of which it swims rapidly through the water. In thirty-six hours it assumes a new form, and speedily changes it for another, after which it returns again to its original form, so that in a very few hours the little creature is first spherical, then oval, then triangu- lar, and then spherical again. In this stage of existence it pos- sesses a foot which enables it to crawl after the manner of snails, and also has organs of hearing and sight.” It does not enjoy its locomotive powers for any long time but fixes itself to some suitable object, passes through its last change, becomes a veritable shipworm and begins its lifelong task of boring. The Teredo is not very particular as to the kind of timber into which it bores, but always goes with the grain, unless it meets with some obstacle, such as a nail or a very hard knot; and in such a case it turns out of its track for a short distance and then resumes its former course. As it bores its way along, it lines the tunnel (as before stated) with a coating of shelly matter, but this is not attached or in any way connected with the body or sub- stance of the shipworm. It is not believéd that the wood it perforates furnishes any - nutriment to the animal, but that its sustenance is derived entirely from the water which is constantly passing through its body. The holes made in the wood at the time or just after the young Teredos commence burrowing are quite small, the appearance of the surface of a pile or other infested timber is usually deceptive, affording but little evidence of the size or number of the burrows - or the extent of the ravages within. After awhile the interior is so completely “honeycombed” that a slight blow or bump by 4 vessel upon the outside shatters the pile, &c., and their damaging work can be seen. ` Upon the water front of San Francisco I have known piles, of Oregon pine and fir over a foot in diameter, rendered worthless in 1886. | The. Teredo, or Shipworm. 135 eighteen months, and have heard of even a more rapid destruc- tion of wharf piles in the harbor of that city. In one instance reported to me the destruction was accomplished in about six months. In the case which came under my notice, as above, the wood of the pile had not lost its original fresh or bright appear- ance when it had to be removed from the wharf and a new one put in its place. My friend, Mr. Dall, informs me of a case of the de- struction of the supports of a small pier made of piles (probably pine) six to eight inches in diameter in about six weeks. The structure was at one of the small capes near the entrance to Chesapeake bay. As the shipworms are gregarious, and furthermore as they grow and multiply with astonishing rapidity, their destructive work is, as shown above, often accomplished in a very short time. The extent of their operations and the money loss entailed thereby, both upon private parties and business corporations en- gaged in commercial marine enterprises and on the naval equip- ment and appurtenances of the great maritime nations, are enor- mous. This has led to a great number of experiments by govern- ments and inventors for the protection of wood work used in Marine structures. Jeffreys remarks that “in all probability the constitution of a shipworm is poison-proof,” Most of the remedies proposed in the last century were of this nature, and they signally failed. The saturation or impregnation of the wood with creosote or some other carbolic preparation by hydrostatic pressure, the kyanizing of piles, and sheathing with copper, the filling of the exposed surface with large-headed nails have all been tried. The two last, copper sheathing and scupper nailing, Jeffreys says, — “have been successfully used, but the former is expensive and the crust of iron (unless they are closely driven in so as to com- pletely cover the piles) is superficial and liable to scale off. I have known the Teredo to bore through a pile which was sup- posed to be protected by large broad-headed nails in the usual way. At Christiania, in April, 1863, I found that Teredo navalis was very destructive to the woodwork in the harbor, and to boats lying at anchor in the fiord. The chief engineer told me that all = — the piles had been creosoted (ten pounds to the square foot) be- re they were driven in, but not to much purpose!” 136 The Teredo, or Shipworm. [ February, Certain kinds of wood are less subject to their attacks than others. The tree palmetto of the Southern States, it is said, is never bored by the shipworm, and some of the Australian woods have similar immunity. Dr. Mueller says of the Eucalyptus mar- ginata (Smith): “ The Jarrah or mahogany tree of S. W. Austra- lia, is famed for its indestructible wood, which is attacked neither by Chelura nor Teredo nor Termites, and therefore so much sought for jetties and other structures exposed to sea water, also for underground work, and largely exported for railway sleepers. Vessels built of this timber have been enabled to do without cop- per sheathing. It is very strong, of a close grain and slightly oily and resinous nature; it works well, takes a fine finish, and is by shipbuilders here considered superior to either oak, teak or indeed any other wood.” * * * The Æ. rostrata (Schlecht), the red gum of Victoria, is another very valuable spe- cies for the “ extraordinary endurance of thewood underground, and for this reason highly valued for fence-posts, piles and rail- way sleepers ; for the latter it will last a dozen years, and if well selected much longer. It is also extensively used by shipbuilders. * * * Next to the jarrah from S. W. Australia, this is the best wood for resisting the attacks of seaworms and white ants. This species reaches a hundred feet in height.” In some of the seaports in different parts of the world there are small crustaceans that assist the shipworms in cutting away what wood the Teredo may leave. These little fellows resemble the wood-louse (pill bug), and cut either way of the grain of the ood. In the inlets around Puget sound the destructive action of both classes of animals may be seen, especially about the time of the summer solstice, when the extraordinary fall of the tide exposes the piles (of the wharves) for their entire length. A space meas- ured up and down on the piles for a length of four or five feet, including the portion exposed between ordinary tide marks, may be seen which is so completely riddled that it would seem as if the slightest loading of the deck of the wharf would result in a tumble down of the whole. The wood-eating crustaceans referred to belong to the groups Limnoria and Chelura. As an offset to the damage caused by these, from point of size insignificant animals, it should be borne in mind, to their credit, that by destroying old wrecks, &c., in channel ways and at the entrance to harbors, they contribute to the safety of navigation. It is stated also that the operations of the Teredo suggested to Mr. Brunel his method of tunneling the Thames. 1886.] = The Flood Rock Explosion. 137 THE FLOOD ROCK EXPLOSION. BY WILLIAM HOSEA BALLOU. ro greatest artificial earthquake in history occurred on Sat- urday morning, October 10,at 11 h. 14 m., standard time. The point of disturbance was Flood rock in East river, on the imaginary extension of Ninety-third street of New York city. The earthquake was projected by means of 300,000 pounds of dynamite and rackarock powder arranged in twenty-two miles of metallic cylinders. It was entirely submarine in character, and surface damage was prevented by a tamp of fully 10,000,000 cubic yards of salt water. Asa spectacle it was simply an Ice- landic or Yellowstone geyser on an extended scale—a sudden rise of water and gaseous smoke to a height of 150 feet for a length of 400 feet and a maximum thickness of 100 feet at the base of the column. The flying rocks and débris sketched in illustrated newspapers are the fickle inventions of inane minds. The column of upheaved water was so enormous that all solid bodies were hidden from vision. The explosion was comparable to a very good earthquake. Inadequate observations —Seismological observations were taken at various points, but the arrangements for so doing were inade- quate and quite primitive. This is a statement of fact, not reflect- ing in any manner on the observers. In the first place there were no seismometers or seismographs in this country. In the second place the engineer corps and scientific corps did not act in conjunction with each other, and the latter received no telegraphic warning of the exact moment to expect the shock. In the third place observers were not stationed at sufficient distances from the center of disturbance to measure the length of radii of earth vibrations. Had there been seismographs located at Buffalo, Montreal, Philadelphia, Washington, Portland, Me.; far out at sea, or at intervals on a direct diameter, say 1000 miles long, the exact length of the radii might have been determined. Further- more, seismographs make an intelligible record with the pencil which none of the observers secured. Results of scientific observations —The record obtained by- the Scientific corps, however, was exceedingly interesting and valua- ble. There were a number of astounding as well as expected results. . The instruments used were the seismoscope, the tele- | 138 : The Flood Rock Explosion, [ February, scope in connection with a horizontal plane of mercury, the sun thermometer, the thermometer, the ł ter, the pluviometer, etc. The shock did not create as much noise as an ordinary field piece. The shock was felt by the feet and indicated by the seismo- scope one-half a second before the result was visible to the eye. The seismoscope, which is supposed to record the beginning of the shock simply, traced an unintelligible record on the side- real time cylinder at the Columbia College observatory. Observers who watched horizontal planes of mercury through telescopes naturally report different results. Professor William Halleck, at Yonkers, N. Y., ten miles from the explosion, records that the vibration of the mercury increased after the first fifteen seconds up to forty seconds, then diminished for ten seconds, ceasing entirely after fifty seconds, Professor J. K. Rees, at the Columbia College observatory, two miles away, and Professor Young, at Princeton, record that the duration of vibration of the mercury was thirty seconds. Professor W. A. Rogers, at Har- vard College observatory, 197 miles away, records that the vibra- tions lasted there two minutes and forty-six seconds. This would show that the earth wave divided constantly as it traveled out- rd. All of the instruments of the Central Park observatory left a record very much to the amazement of Professor Daniel Draper and other meteorologists. Why, for instance, should such a dis- turbance in any way affect the sun thermometer and rain gauge? The former recorded 121° in the sun, when suddenly the pen, which was tracing its record on paper, made a straight mark eight degrees long at right angles with the regular tracing and with four degrees on each side of it. This would naturally show a decrease or increase in the sun’s temperature, whereas it was really an interruption of the sun’s record by an abnormal cause. Professor Draper thinks that this record must be of great value to seismologists. I think it shows that the record of a sun thermometer, as indicated by a tracing on paper, cannot be relied upon, since any jar is liable to affect it. The pluviometer, or rain gauge, also gave an uncalled-for record of one-eighth of an inch. While these records may be of value to some one who can utilize them, to my mind they only demonstrate the fallacy of placing any value on the record of these instruments as traced on paper. 1886.] The Flood Rock Explosion. 139 The atmospheric wave.—The vibrations of the air were exceed- ingly slight, owing to the heavy tamp of water. The greatest fall of the barometer was .02 of an inch. The wind being in the west and blowing eight miles per hour, the slight atmospheric wave was naturally carried out to sea, so that its duration and ex- tent are lost. The earth wave.—The velocity of the earth vibrations was one mile in seven-tenths seconds at the outset, decreasing to one mile 434ths seconds, as far as measured. The notated diameter of the shock was 394 miles long. Itis safe to approximate the diame- ters (supposing that observers had been on the watch at sufficient distances) at 800 miles. For if-the shock was sufficient to reach the Cambridge observatory, 197 miles distant, in 194 seconds, and shake that eternal structure as it had never been shaken before, it ought to have doubled the distance with some perceptible effect, giving a radius instead of a diameter of 394 miles. Scientific value of the observations —The Flood rock explosion cannot be called a surface disturbance because it occurred at the sea level. Volcanic and geyser eruptions vary in altitude and have a vibratory power downward. All of the vibratory power. at Flood rock was upward, which makes its effect all the more wonderful, since the farther the shock traveled the more of the earth surface it had to lift on account of the constant rise above sea level. Enough explosives were used to have obliterated Manhattan island if placed on the surface, or to have leveled Mt. Washington. The fact that 300,000 pounds of explosives will affect a surface of 300,000 square miles does not necessarily settle the question as to the cause of earthquakes. It does not verify the belief that explosions of some kind cause earthquakes, but leaves us in the dark as to the composition of such explo- Sives.

Flood rock answers these questions in part. It says that explosions of some kind do the work; but this answer only opens the door and points to a sea of data yet to be secured as to the nature, component parts and modus operandi of these explosions, which differ evidently in dif- ferent cases. Note —The seismological, observations to determine the dura- tion and extent of the earth and atmospheric waves were taken on two lines running at right angles with each other. General Henry L. Abbot, of the United States Corps of Engineers, had charge of the observatories on an east and west line on Long Island, with headquarters at Willet’s point. The north and south line was in charge of Professor F. W. Clarke, of the United States Geological Survey, Washington. He had his southern ‘station on Staten island, in charge of Professor H. M. Paul of the United States Naval observatory. At the next station, on Ward’s island, Professor T. C. Mendenhall, of the United States Signal Service, and himself observed. At Yonkers Professor William Hallock, of the United States Geological Survey, and student Thomas Ewing, Jr., of Columbia College, occupied a station. The most northerly observatory of the chain was at Vassar Col- lege, in charge of Professor Maria Mitchell. Dr. Daniel Draper took observations on a number of instruments at Central park. The astronomers at Princeton, Harvard and Rutgers colleges also made observations in conjunction with the others. EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. It is safe to say that the greatest necessity of scientific progress in the United States to-day is schools and academies of original research. We have colleges and universities enough in most of the States, but there has not yet been established a single school where knowledge is produced, which corresponds in scope with the numerous institutions where it is taught. Perhaps it is a general impression that there is already more knowledge in the world than can be learned; but, if this be true, it can not for a moment obscure the geat truth, that most of the laws of nature remain still, more or less, unknown. It i is, or ought to be, 1886. ] Editors’ Table. 141 well known, that all the knowledge taught in the schools is the product of original research, and that all books of any value in libraries, excepting works of the imagination, are derived from the same source. Hence, it appears that the absence of schools of research is a phenomenon for which it is difficult to account. There are some schools of this kind which cover a limited part of the field of knowledge, such as the summer schools of biology on the coast; and there are some museums where a limited amount of research is conducted, as much as their financial and intellectual resources permit. But these institutions are either so limited in means, or so completely under the control of non-investigators, that they are ineffective at present, or offer rto prospect of pro- gression in the future. If any public-spirited citizen desires to erect for himself a unique and enduring monument, such can not be more effectively and usefully done than by the endowment of an Academy of Original Research. Such an institution would be a perpetual spring and source of knowledge and truth, and a living “nucleus” in the great organic body of society. An institution which should cover most of the ground might be organized on the following basis: Six departments might be established, namely: 1, Astronomy; 2, Physics; 3, Chemistry; 4, Geology; 5, Vegetable Biology; 6, Animal Biology. For each of these departments the annual expenses would be as follows : For salary of director $3,500 For salary of assistant . 1,000 For material (apparatus and specimens) 3,500 For books 500 which is, for the six departments, $51,000. Then there should be $7,000 per annum for publications, leaving $2,000 for janitor and other necessary expenses. The total income of $60,000 represents an endowment of $1,000,000. Of course, the details might be varied according to probable necessities, etc. And for a smaller endowment, fewer departments might be created, but not without Seriously crippling the institution. Various details, such as the boundaries of the departments, the duties of assistants, etc., would have to be fixed. A certain number of lectures should be given by the directors, which should serve as an index of the charac- teristics of the workers and their work. | 142 Recent Literature. [ February, In the selection of the men who should act as directors of the departments, the principal difficulty is to be encountered. The enterprise of the American is no less marked in the struggle for place and reputation, than in the struggle for the almighty dollar. Qualification is little thought of by too many persons, who from physical or mental weakness, or some other cause, desire to live without labor. The charter of an institution of research should embrace a provision, that the position of director should be for- feited by that one who should not produce some original work of merit every year or two, or during some other definite time. In no other way could the institution be preserved from the intellec- tual decay into which so many have fallen; and in no other way could it be protected from patrons whose kind intentions might include personal ‘favorites unknown to scientific research. Men of money who desire to sustain original research will be com- pelled to devote some inquiry as to who are the men who are loyal to this work. The best index they can find to this class is the record of their work already done. The best mode of government of such an institution would be by a senatus composed of the six directors of the departments and an equal number of trustees of the endowment. In this way the greatest amount of wisdom would be brought to bear on the two questions of administration, viz: the preservation of the fund, and the manner of its expenditure.—C. ae RECENT LITERATURE. farther, and has actually discovered at the end of the tail and on the back of the young embryo of Pristiurus and of Scyllium homogeneous structures (Hautknopfe) of subepiblastic origin, 0 the same substance as the horn-fibers or actinotrichia in the fin- folds. These button-like structures are found on the back of the embryo, in a single row, on either side of the median line and in advance of the permanent dorsal. At the end of the tail they are in two rows, viz., a dorsal and a ventral series. In both situations they are metameric in position, and sections show that temporary muscular buds are thrust outward towards these singular lateral larval organs from the muscular segments or myotomes in the same way as to the bundles of fibers or actinotrichia representing rays in the median and paired fins. These remarkable organs Mayer regards as the vestiges Or remnants of parapodia, and therefore names them parapodoids. 1 Die unpaaren Flossen der Selachier. Mitt. Zool.

It will thus be seen that Mayer supplies a most important set of data which lend support to the views of Dohrn as to the mean- ing and origin of the median and paired fins, since that author has contended that the relations of these peripheral structures to the axis of the body are to be determined by the relations they bear to the myotomes which send out muscular buds into the fins, and not on the basis of the relations to the cartilaginous appendicular skeleton or spines, as held by most other morphologists. The table which Dr. Mayer gives to illustrate the varying rela- tions of the same metameric elements of the median fins to the point where the vertebral axis becomes diplospondylic are also of great interest, not only morphologically, but also taxonomically. or the first time in the history of the subject, in fact, we have presented in this paper a tabulated statement of what are the actual relations. of the metameric elements of the vertical fins to logical methods. It is to be regretted that the author does not give a brief summary of his results at the close of the paper These researches, it may be remarked in conclusion, also show that in Scyllium there is developed a posterior terminal, vermi- form section of the embryo which corresponds to what the writer has called an opisthure. Though it is obvious that this opisthure is rudimentary and evanescent, as it soon becomes inconspicu- ous. Some of the Elasmobranchii, therefore, pass through what the writer has termed an archicercal stage. The results reached by Dr. Mayer also afford important evi- dence in support of the archistome theory, published by the writer in this journal recently..—/John A.

[ February, have half a dozen or more, each giving valuable and needed help to the young investigator. The latest of these manuals is the one now before us. The book, we are told in the preface, is the outgrowth of work done in the Normal School of Science at South Kensington, dur- ing several years under Mr. Dyer, and afterwards to the present under Mr. Bower. Originating in this way, the book is not open to the objection of impracticability which so frequently may be brought against works of this kind, and the beginner may take it up with confidence that he is not asked to undertake that which for him is still impossible. A book which has grown into being is always helpful, and this will prove no exception to the rule. There are in the beginning of the book a couple of introduc- tory chapters in which are discussed briefly, and yet satisfactorily, the making of preparations—micro-chemical reagents, the general structure of the cell, the micro-chemistry and the micro-physics of the cell. Altogether, fifty-three pages are given to the fore- going topics. In the succeeding pages are taken up first the Phanerogams and afterwards the Pteridophytes. The sunflower (Helianthus annuus) is taken very properly as the representative of the herba- ceous, dicotyledonous angiosperms. This is followed by a study of the arboreal type represented by the elm (Ulmus campestris). The monocotyledons are principally represented by Indian corn (Zea mais). Inthe Gymnosperms the Scotch pine (Pinus sylves- tris) is used for study. In each case, stem, leaf, root, flower and embryo are successively taken up and carefully studied. The same method is followed in the Pteridophytes, where Selaginella, Lycopodium, Aspidium and Equisetum represent the different types of structure. The general plan of the work is the same as that of Huxley and Martin’s well-known book, “ Practical Instruction in Elemen- tary Biology,” and the faults of the present work are identical, as appear to us, with those of its forerunner, While such books ‘are very useful, and while they are doubtless doing much to stim- ulate better work, we have long been of the opinion that alto- gether too much help is given in them to the pupil, and that he is not thrown often enough upon his own resources. It is true, of course, that in the laboratories of many teachers, books of this kind will not be used in such a way as to work to the disadvantage of the pupil, but in many other cases—in too many cases—they will be. In making these strictures upon the book, we would not be understood as criticising the method of study of which it is the outgrowth. As to that there can be but one opinion ; but unless great care be taken by the teacher and pupil, the results originally obtained at South Kensington without the book will not secured with it. The book must be used as a general guide, and 1886. | Recent Literature. 145 must not be blindly followed paragraph by paragraph and page by page. Its proper function is suggestive, and, if so used, it will prove of great value in the botanical laboratory. We cannot omit commending the form which the publishers have given the book. The type, printing, paper and binding are excellent, the flexible covers being especially commendable.— Charles E. Bessey. TorREY’S BIRDS IN THE BusH.’—This is a dangerous little book. Young naturalists who have chosen paths that are not those of song and color should avoid it, lest they also should, by its win- some sweetness, be charmed to become ornithologists. Birds appeal to other faculties beside those of the intellect. The musi- cian, the poet, the painter, all find inspiration in the oscines, Per- haps this is the reason there is so much twaddle written about birds. Since there is an audience writers devoid of the artistic, poetical, or musical faculties pen a series of quasi-scientific me- anderings, and send it forth as a bird-book. But Mr. Torrey loves bird-song and bird-beauty and tells his love in language remarkable for force and picturesqueness. The eleven chapters teem with the result of years of life among the birds, and the author has a quaint way of comparing bird-life and bird-ways with our own life and ways, without allowing the reader to forget that it is only a bird he is talking about. No heavier blow has been dealt the sparrow-hater than that given in the first chapter of this book. Though by no means a sparrow-lover, Mr. Torrey confesses that, in the space of the last seven oreight years, he has watched upon Boston Garden and Common some thousands of specimens, representing not far from seventy species. The author Owns to the true aboriginal temperament—he loves to be out of doors, but hates out-of-door employment; this is the stuff orni- thologists should be made of, plus eyes. Neuchatel, his correspondence with Humboldt, his nine summers Spent in Alpine exploration—this volume will seem like a ro- mance. To those who never saw this child of genius, the second volume, recounting his successful life in America, the Iand of his adoption, will be full of interest. ` Birds in the Bush. By BRADFORD TORREY.

[ February, As a youth, Agassiz was indefatigable as a collector, personally attractive, full of high impulses, and his whole mind pervaded with the scientific spirit. His early dreams were fully realized; his castles in the air were actually built—he laid their foundations and saw the superstructures materialized in richly illustrated vol- umes and in brick and iron. The vast collections—the results of his journeys, of his passionate appeals to State and individuals, the unsolicited funds which flowed in as the meed of his success in winning the confidence and sympathy of scientific and lay men —these fill the Museum of Comparative Zoology, that monument of a life of rare devotion to high ideals. _ Agassiz was a genius, Winning in manner to an unusual degree, full of ardor and enthusiasm, often reckless, but always success- ful, with a grain of fanaticism and one-sidedness in his nature, like a knight of old he won his proud position as one of the leading scientific men of his age and the most influential and popular teacher in the New World. _ Agassiz had great powers of generalization, side by side with those of acquisitiveness, of facts and specimens. His investiga- tions in embryology, palzontology, as well as systematic zoology, led him to form clear views as to the geological succession of animals, the parallelism between the development of the individ- ual and the group to which it belongs. His mode of looking at nature, the whole drift of his teachings, naturally prepared the mind for the reception of evolutionary ideas, and while his pupils and his contemporaries advanced naturally to these philosophic conceptions or generalizations, Agassiz,—whether owing to early prejudice, the lack of a judicial turn of mind and analytical powers, the modicum of combativeness and bigotry in his strong,’ intense nature, or the multiplicity of his labors and cares in the later years of his life, which gave him little time for sustained: thought,—failed to rise to the grand generalizations of modern biology.

Yet the disappearance of the forests marks some diminution in the water-supply. Later writings, about the sixth century B. C., state that the Saraswati sinks into the earth, and gives the Ganges and Jumna at their confluence. This is probably a fable to save the credit of a sacred river. The Sutlej and the Indus rise on opposite sides of Mount Kailas, at elevations of about 15,200 and 18,000 feet respectively, and both flow north-west for a considerable distance, and then turn to the south-west, the Indus taking the wider sweep, and enclosing, between itself and the Sutlej, a broad tract containing the other four rivers and their drainage basins. Much of the upper courses of all these rivers is torrential, but the Indus runs with a gentle and winding current through Ladak at a height of 11,000 feet, and the lovely valley of Kashmir is situated near the sources of the Jhelum, which is even there a large river, since several tributaries join at Islamabad, forty miles above Srinagar. At Baramula, the Jhelum leaves Kashmir, and falls thirty-five feet per mile for seventy-five miles, and then twenty-one feet per mile to the Punjab plains. The earliest of the metrical histories of Kashmir state that the valley was once a lake, and that a powerful sage cut the gap at Baramula. It is not impossible that it was e work of man. Seventy-five miles of the upper course of the Beas have a fall! of 125 feet per mile. The courses of all these rivers after reaching the plains of the Punjab are, like those of the Mississippi and other rivers which have flood plains, subject to much disastrous change. The rainfall of the higher portions of the Punjab, where the rivers leave the hills, varies from thirty-four to forty-eight inches. At fifty miles from the hills only sixteen to twenty-four inches of rain falls, and at 100 miles, but ten to twelve inches. Where the rivers unite, no more than six inches of rain falls annually, and still less than this visits the desert plain of Sind, through which the mighty Indus, after receiving the five rivers, flows to the ocean. The five rivers unite before reaching the Indus, and the united stream, called the Panj-nad, or five streams, is at the junction more than twice the width of the Indus, but much shallower. The discharge of the Panj-nad at the low season, is estimated at 69,000 cubic eet per second, that of the Indus at 92,000. The flood discharge below the junction is about 380,000 cubic feet. A very large amount of water borne down by these rivers sinks into the ground, and forms an underground reserve of water, which even in the rainless region round near the meeting of the five rivers is not more than twenty-four feet below the surface. a Himalayan Peaks——According to notes communicated by Some .

M. Potaneri’s Fourney—M. Potaneri has made interesting dis- coveries in Northwest China. The broad valley of the Tchitai, a tributary of the Hoang-ho, is thickly peopled by Salars (Turco- mans), its upper part by Tanguts. The right bank of the Hoang- ho itself, near San-chuan, is also peopled by Salars. They main- tain their Turkish language, and the Mussulman religion, but their mosques are Chinese in style, and the men wear a Chinese dress. The women wear broad trousers, an overcoat with sleeves, and a pointed bonnet. Above the gorge near San-chuan (excavated in the red sandstone and conglomerates which under- lie the Loess), is a depression seven miles long, peopled exclu- sively by Mongolian Shirongols, who seem to belong to the same stem as the Dalda of Lake Kuku-nor. The Chinese call both Tu-jen. They speak Mongolian, with some Chinese words, an _dress like Chinese, but the women wear trousers like the Salar women. Around He-cheu they are Mussulmans, but Buddhism and the teachings of Confucius are followed by some. Asiatic News-——M. Ivanoff has recently described in the Isvestia, the remains of Akhyr-tash, at the foot of the Alexander range in Turkestan. The area covered by the remains is 20,900 _ square yards, and the stones weigh each about a ton. Some stone -idols and a burial-ground on the Tssyk-tul are also described. The Kampti villages on a tributary of the Irawadi, visited by Wilcox, sixty, years ago, have again been visited by Col. Woodthorpe. Only a very ordinary road is required to open up 4 - trade with these people from Assam. Mr. Gardner considers Mukden, the capital of the Mongolian province of Féng- Tieng, as one of the finest and most prosperous cities of the Chinese . empire. The population of the province is chiefly Chinese.

Since 1876 hundreds of thousands of emigrants have arrived from Shantung and Chihli, and have broken up and cultivated land on both sides of the Great Wall or Palisades. The site of Newchang, the port of Féeng-Tieng, was in the seabed up to the beginning of this century. The province of Korin contains a large community of Coreans. About 48,000 square miles, or 5% per cent of British India, has been reserved as forests. Some are upon the plains or on the low ranges of hills rising from them, some on the lower or middle slopes of the Himalayas to an elevatlon of 8000 to gooo feet. A forest sur- vey is in progress, largely in the lands of native surveyors trained in the Forest Survey Department. A school of Indian forestry . has been established, in which natives are trained to be conserva- tors and rangers. America.—The Claims of France in Brazil—M. Condreau calls attention in a recent issue of the Revue Scientifique to the undetermined portion of French Guiana. Upon maps the river yapock is shown as the south-eastern boundary of French Guiana, separating it from Brazil, while the southern boundary is formed by the Tumac-Humac mountains. It appears, however, that France has at, various times occupied and abandoned the ter- ritories between the Oyapock and the Amazons, and that the peoples of that region live actually independent of either Brazil or France. M. Condreau states that Brazil once offered to divide this territory, but that France claimed two-thirds. In any case, the country in dispute is worth having, since it is not an un- healthy marsh like Guiana itself, but an elevated healthy prairie country tilled for colonization. The region offered to France in 1856, between the Oyapock and the Carsevesme, is as large as three French departments ; while that claimed by France, ending at the Tartarougal, contains twice the area. _M. Condreau argues for the acceptance of the Brazilian propo- sition.: Arguments about rights make it clear toa hman that France ought to own all the country north of the Amazon as far as the Rio Negro, and equally clear to a Brazilian that Brazil owns to the Oyapock, Diplomacy has tried to settle the matter for two hundred years. Most of this territory has been settled by Brazilians, but the coast and prairies back of it are occupied only by Indians. He proposes a Franco-Brazilian commission to settle the matter. The first need is a good map. The seaboard is sub- Ject to continual change, especially between the Mapa and Cabo de Norte. During the last forty years much alluvial land - has been made by the rivers. Of the interior country, and of the Island of Maraca next to nothing is really known, American News.— Lieutenant Cantwell has explored the river Futnam to its source, 520 miles from the mouth. It rises in four large lakes; the largest is about 153° W. long. and 67° N. lat. 152 : General Notes. [ February, He found that there was an easy communication between Kot- zebue sound and the Yukon. Mr. B. McLenegan, with one sailor, ascended in a canoe the river Nortauk, which enters the Arctic ocean at Hotham inlet, for a distance of 400 miles. Here one of the head streams of the river issued from a small lake. No inhabitants were met’with. The course of the Nortauk is entirely in the Polar circle, and the lake in which it rises is the most northerly inland point yet reached by white men in Alaska. A rich deposit of coal of good quality has been found at Cape Lisburne (69° 37’ N. lat.). From the observations made by the Alert, it appears that Hudson’s bay and strait are navigable from July to October, and that the climate of the Hudson’s bay coast is less severe than that of Northwest Canada. Lieut. Allen has returned to San Francisco from an exploration of. the Copper river, which he ascended as far as the mountain range of Alaska. e then crossed the mountains on snow-shoes, and reached the sources of the Tennah, which he followed 800 miles to its junction with the Takon. The latter he descended to its mouth, a distance of 400 to 500 miles———M. Thonar has left Buenos Ayres to complete his explorations on the Pilcomayo. Captain L. Gray found, during his visit to the east coast 0 Greenland last summer, that the land ice was sufficiently open in August to afford passage for a steamer. He sailed along the coast from Shannon island to the entrance of Scoresby sound. J. Hughes and F. Dunsmuir have returned to Juneau, Alaska, from the headwaters of the Yukon. Good placers were found, mostly in British territory. ‘he governments of the gentine confederation and of Brazil have agreed to a joint exploration of the neutral or disputed ground on the western limit of the Brazilian province of Sta. Cateria, situated between the Uruguay and Iguassu rivers. An old treaty between Spain and Portugal fixed upon two rivers, the Peperi and San Antonio, the first flowing into the Igyassu, the second southward to the Uruguay, as the boundary; but the difficulty is to identify the rivers so called in the treaty. Lieut. Greely, ina recent lecture at Dundee, stated that the temperature observations taken during his stay in Grinnell sound confirmed the expectation that it had the lowest mean temperature known, about 4° F. below zero. The discovery of coal at various points showed how climate had changed. He doubted the existence of a palzocrystic sea. floe bergs from 100 to 1000 feet thick, are, in his belief, detach- ments of slowly moving ice-caps from a land near the pole. ! ` Kane sea he visited a floe berg a third of a mile wide and a fifth to a sixth of a mile thick, and found upon it two valleys thirty feet deep, along which were fully 100 large stones polished and worn smooth—proofs of the glacial and terrestrial origin of the 1886. | Geology and Paleontology. 153 AFRICA.— Capello and Ivens’ Fourney—Messrs. Capello and Ivens reached Lisbon on Sept. 17th, after traveling 4200 geo- graphical miles in Africa during fifteen months. From the Portu- guese territory they proceeded towards the Cubango, as far as the lower part of the Tucussu, where the barrenness of the region, intersected by water-courses and marshes, forced them to turn northwards through a district infested by the tsetse. Sixteen of the party died of tsetse-bites, besides cattle and dogs. Sixty-two men perished during the fifteen months. The principal results of this journey are the rectification of the course of the Cunene, the determination of the Quarrai and its union with the Cubango, as well as the interesting hydrography of the Handa and the Upper Ovampe ; the exploration of the Cubango between 15° and 17° S. lat., and of its principal eastern affluents ; the investigation of the basin of the Upper Zambezi to Libonta, and the upper and middle course of the Cabompo; the discovery of the Cambai, an eastern branch of the Upper Zambezi; the exploration of the sources of the Lualaba and Luapula, and of the northern tributa- ries of the Middle Zambezi; and the identification of the Loengue with the Kafuke. The great lake Bangweolo of modern maps is really composed of two smaller lakes, Bangweolo to the north, © and Bemba to the south, separated by a marshy belt. This agrees with M. Giraud’s account. GEOLOGY AND PALAIONTOLOGY. THE STERNUM OF THE DinosaurIA.— The discussion which has been going on between paleontologists, as to the nature of the sternum of the Dinosauria, and the presence or absence of clavicles in this order, induces me to present some evidence which bears distinctly on the question. The first point to be noticed is the pair of bones represented in Fig. 1, which belongs to the skeleton of Diclonius mirabilis Leidy! It is evident that these Diclonius, I cannot give their exact relations. The positions in which the bones were found by Dollo in the Iguanodon renders it highly probable that they are the separate pleurosteal elements of the sternum. The long processes will then be posterior, and will have given attachment to ribs. Such a type of sternum is, however, unique, and requires good evidence before admission into our descriptions. : Important evidence on this point is furnished by the probable corresponding element in the Laramie dinosaurian, the Mono- clonius crassus Cope’ This is a quadrupedal form, aboutaslarge = 1 Proceedings Academy, Philadelphia, 1883, p. 97. : ?

Here the lateral elements are united on the middle line, which projects as an obtuse keel. The lateral processes are nearly transverse, and are impressed at their extremities by articular surfaces. The opposite extremity presents a facet on each side for a squamosal articulation with a flat bone (c, Fig. 2), in which the inferior bounding ridge projects much further than the superior one. This articulation cannot be for any other bone than the coracoid, and it resembles considerably the corresponding groove on the sternum of the crocodile. The general surface of the bone is dense, and does not resemble the imperfect ossification described by Hulke in the bone of similar character referred by him to Fig. 1.

That the element in Monoclonius, represented in Fig. 2, is the sternum, seems very probable, and, if so, the ele- ments in Diclonius (Fig. 1) are sternum also, The T-shaped bone figured by Hulke, if inverted, would resem- ble the elements here referred to the sternum in Diclonius and -Monoclonius. Mr. Hulke describes a probable articular facet along its sides “ posterior ” (anterior) to the divergent bars, as - suggesting an articulation with an epicoracoid. This may cor- respond with the facet c in Diclonius and Monoclonius, which, I suppose, received the edge of the coracoid. This justifies the proposition of Baur,’ that this bone should be inverted, and that the supposed clavicles of Hulke and Marsh are posterior pro- 1 Quarterly Journal Geological Society, 1885, pl. xrv. 2 Zoologischer Anzeiger, No. 205, 1885, p. 2. : fe E E U ae E R I E SN 1886. ] Geology and Paleontology. 155 cesses of the sternum and not anterior. The evidence for this position rests primarily, I repeat, on the position of the bones observed by Dollo, and the character of the corresponding ele- ment in Monoclonius. But it may be that the bone figured by Hulke is a different element from that figured by Dollo, as supposed by the latter.* The proximal end of the scapula of Dizclonius mirabilis resem- bles very much that which I have figured and described as belonging to Hadrosaurus foulkei? excepting that it possesses a strong tuberosity on the anterior border (spina scapule), which is wanting in that species. It is represented as weak in the two species of Iguanodon by Dollo, and as rather strong in the same genus by Hulke.—Z. D. Cope. Corrections oF NOTES on DinocerAta.—In the NATURALIST for June, 1885, I gave a synopsis of the, genera of this suborder, which was partly based on new information derived from Professor Marsh’s work, then recently published. Among them was included the supposed genus Tetheopsis, whose character consisted in the absence of inferior canine and incisor teeth. The discovery of species presenting such a peculiarity would not be at all surprising in view of the reduction which the roots of these teeth display in some of the species, and the absence of superior incisors in all of them. The character on which the genus was predicated is figured by Professor Marsh in the skull referred to Tinoceras stenops Marsh, without comment in the description which follows. I now learn on good authority that the sym- physeal region in the specimen in question is entirely constructed of plaster of Paris. I saw the specimen, and a rather close examination did not reveal the line of separation between the plaster and the bone, which it is colored to imitate, and which is not indicated in either Professor Marsh's figures or description. The genus Tetheopsis must then be regarded as an artifact! I add that the basal part of a skull which I described under the head of Uintathertum lacustre Marsh (U. S. Geological Survey, Terrs., 111, p. 592) turns out to belong to a Palzosyops. The skull was found in a broken. condition mingled with loose frag- ments and teeth of the Uintatherium in such a way as to lead to the belief that they belonged together.—Z. D. Cope. DISCOVERY OF LAMELLATE THORACIC FEET IN THE PHYLLO- CARIDA.—In a genus of Phyllocarida, allied to Ceratiocaris, which is represented by a specimen from the Carboniferous beds Mazon creek, Illinois, kindly loaned me by Mel Carr, of Morris, Ill., there are plain indications of broad lamellate feet like the thoracic feet of Nebalia. os Of these limbs there are traces of four pairs. They are broad : l Revue des Questions Scientifiques, 1885, p: 8, top. ransactions American Philosophical Society, 1869, XIV, p. 92. 156 General Notes. [February, and thin, slightly contracted in width near the base, and at the distal extremity quite regularly rounded, with the free ends appar- ently slightly folded longitudinally, the edges appearing to be. slightly crenulated, though the folds were perhaps due to changes after death. the feet are of nearly the same size, and are about two-thirds as long as the carapace is high, being of nearly the same proportionate length as in Nebalia. There are no traces of a division into endopodites and exopodites, but we should be inclined to regard the parts preserved as the homologues of the exopodites of Nebalia. This specimen, then, indicates the existence in extinct Phyllo- carida of thin, broad, lamellate, thoracic limbs, in general appear- ance like those existing in Nebalia, and should this view be sub- stantiated by farther discoveries it will prove the reasonableness of uniting Ceratiocaris and its allies with the modern Nebalia. I had a year ago considered this form as new and gave it a MS. name Cryptozoé problematicas, as I was in doubt as to its affinities; but lately submitting it to Mr. C. E. Beecher, with the opinion that it was a Ceratiocaris, he writes me that he regards it as new to sci- ence. A description of the new genus and species, with figures, will appear hereafter —A. S. Packard. GEOLOGICAL SURVEY OF PENNsSYLVANIA.—Report of Progress X contains a geological hand-atlas of the sixty-seven counties of Pennsylvania, and is the work of J. P. Lesley, the chief of the sur- vey. The volume is one which ought to be in the hands of every one interested in field geology, embodying as it does, in convenient form, the entire results of the survey, so far as they can be carto- graphically represented. The maps are prefaced by an explanation of the geological structure of Pennsylvania,and a short account of e characteristic features of each county. GEOLOGICAL SuRVEY oF Munnesota.—Professor Winchell’s Twelfth Annual Report commences with a summary statement of work done. From this it appears that maps of thirty-two coun- ties are completed, and several others in course of preparation. A new trilobite of the genus Bathyurus is described. Professor Winchell gives an account of experiments with cubes of New England and Minnesota granites, and seems to prove the latter to be the stronger. . 3 C. L. Herrick contributes a final report on the Crustacea of Minnesota (Cladocera and Copepoda). This occupies 191 pages, includes an account of the enemies of entomostrza, and appears to be exhaustive. It is illustrated with numerous plates. The volume concludes with a catalogue of the flora, by Warren Upham. It includes 1650 species, comprising vascular crypto- gams, but not fungi or alge.

Silurian—Dr. O. Hermann (Geol. Mag. Sept., Oct., 1885) gives an account of the organization of the Graptolithide. The entire polypidom proceeds from a simple hollow cone called the sicula. In the external wall of this dagger-shaped organ a single or double solid axis is developed. Thus, until the sicula is found, it is impossible to tell whether any given form belongs to the monograptide or to a two-branched family. Sprouting does not always commence at the same spot of the sicula. It is now assumed that all graptolites provided with a sicula were not attached bodies, the character of the termination, and its disap- pearance in full-grown individuals, militating against attachment. In some of the much-branched Dichograptidz a central chitinous disc unites the basal part of the branches. It has been ascertained by Hopkinson that in some graptolites the hydrothecze were separated from the coenosarc by a well-marked septum, and that the ccenosare was divided by septa into transverse joints. The oldest graptolite, according to Brogger and Hermann, is Dictyo- grapius teneilus; and the family Dichograptide, which includes complicated and elegant forms of graptolites, is older than the universal groups. This family appears in the Lower Silurian (Waring), becoming extinguished before the Upper Silurian is reached. The Phyllograptidze and Lasiograptidz seem to be con- : fined to the lowest division of the Lower Silurian, the Leptograp- tide and Dicranograptide to the Lower Silurian, while the Diptograptidz and Retiohtes commence in the lowest Lower Silurian, but are most developed at its upper boundary, and extend into the Upper Silurian. The simplest family, the Mono- graptidæ, are, according to Lapworth, strictly confined to the Upper Silurian. The genus Dictyograptus, of which Tullberg makes a new family (though Hermann ranges it with the Dicho- graptidæ), maintains itself through the entire Silurian, and passes into the Devonian. Devonian.—Professor Williams has described (Geol. Mag.,Sept., 1885), Prestwichia eriensis, a new Limuloid from the Devonian of Le Bouf, Erie county, Pa. enland. The second or Mill creek series corresponds closely to the Dakota, and seems to represent the flora of the Cenoma- 158 General Notes. [February, nian and Turonian divisions of Europe. The third sub-flora is that of the Belly river at the base of the Fort Pierre group. Though separated from the Laramie by the Pierre and Fox hill groups, it introduces the Laramie or Dominion flora, which con- tinues to the top of the Cretaceous, and probably into the Eocene, and includes several species still surviving in America. Next comes the Laramie group itself, the fossils of which are found in Canada, chiefly in the lower and upper beds, the middle beds being poor in plants. Sir W. Dawson concludes that no cause for the mild temperature of the Cretaceous other than change of elevation need be invoked. Tertiary —According to Woodward, fifteen species of fossil sirenians have been referred to Halitherium, while two consider- ably larger species, both found in Italy, are placed in Felsinothe- rium, and closely resemble Halicore in dentition. Prorastomus isit c.i4 p.m. m.33=48. Felsinotherium has i }} m. 33. An interesting discovery was a cast of the interior of the skull of Eotherium egyptiacum at Mokattam, near Cairo, in 1875. The brain of the huge Rhytina is only one-sixth of the size of that of the manatee or dugong. The total number of extinct sirenians enumerated by Woodward, including Chirotherium from Pied- mont; Chronozoon from New South Wales; Crassitherium from Belgium’; Dioplotherium and Hemicaulodon from South Carolina and New Jersey; Pachyacanthus from near Vienna; Rhytiodus and Trachytherium from France, and two extinct Manati, is twenty-eight. The recent species are three of Manatus and three of Halicore. Dr. Murie believes that the large number of fossil species described will probably have to be reduced into two or three genera.

In order to study more closely the connection between the figures produced by weathering and those produced by etching, Blasius,! of Strassburg, subjected a number of sub- stances in crystal form to the action of alcohol, and also placed them in desiccators with strong sulphuric acid. As the result of a large number of experiments, he concludes that many of the figures produced by weathering (including etched figures) cannot be brought into close relation with the directions of cleavage or the curves of hardness in the substances acted upon. Moreover, their shapes differ according to conditions, and, finally, from a knowledge of the etched figures on a number of faces the shape of those on others can be deduced. F. Becke? adds further to our knowledge in an article on the etched figures of minerals of the magnetite group. Magnetite, spinel, franklinite and linneite were treated with sulphuric, nitric and hydrochloric acids of dif- ferent concentrations and during periods of different lengths, and besides with alkaline solutions. 1. On all the crystal faces, the figures were composed essentially of the same planes of etching, the principal planes of etching. 2. The principal planes of etch- ing lie in a determinate zone. 3. These planes of etching offer the greatest opposition to the action of solvents. 4. Depressions are formed on such faces as belong to the zene of etching, eleva- tions on those which lie far without it. 5. Cleavage planes can- not, at the same time, be planes of etching. 6. Linnzite, when etched with acids, deports itself like magnetite; when treated with alkaline solutions, an entirely different plane becomes the principal plane of etching. Consequently, it may be assumed that “the elemental atoms in the crystal molecule maintain a definite position with relation to one another.” In linnæite (Co,S,), for instance, “the cobalt atoms are turned toward the cubic faces and the sulphur atoms toward the dode- cahedral faces,” because when treated with acid the cubic faces are dissolved fastest, but when treated with fused potash, the dodecahedral faces offer the least opposition to the solvent action of this reagent. Baumhauer* makes practical use of the method of etched figures in an investigation ofthe character of the massive bornite from Chloride, N. M. When a polished sur- face of this mineral is treated with nitric acid it breaks up into several fields, each of which reflects the light differently, showing that the massive material is made up of an irregular intergrowth of individual crystals. At the same time the fact is brought out twinned inclusions of chalcocite and chalcopyrite are not ommon. i Zeits. für Kryst. und Miner., X, p. 221. 3 Min. und Petrogr. Mitt., VII, p. 195.

[February, ANDESITE.—The question of the best definition of andesite is of plagioclase and hornblende; and Lagorio as a volcanic rock composed of plagioclase, with the addition of augite, hornblende or mica. Rosenbusch’ separates the mica and amphibole ande- sites from the augite andesite. Siemiradski finds that the same lava-stream varies in acidity, and that, though hornblende is more n r in ve silica, while hornblende is eitively lacking. “No indication of the regular sequence of separation of augite, hornblende and mica with i increasing acidity, as observed by Hague and Iddings,* can be detected.” He suggests as the best definition of this class of rocks the following: Neutral or acid plagioclase rocks, with at least fifty-five per cent of SiO,, with trachytic, basaltic or phono- litic habit, consisting of porphyritic andesine, with an iron- -rich pyroxene, hornblende or mica in a groundmass, composed essen- tially of an acid andesine or oligoclase, and an acid glass (mixture of oligoclase on haere and amorphous silica) containing micro- scopic pyroxen The Borbhyritic hornblende of these Ecuador‘andesites is sur- rounded by an opacitic rim and contains inclusions of the ground- mass, which, under the microscope, are seen to consist of feldspar and augite microlites. Moreover, it is not confined to the most acid varieties. Consequently, the author suggests that it may have been produced, at great depths, in a magma saturated with superheated steam under great pressure, while the augite crystal- lized from a dry magma under comparatively little pressure—a theory very different from the one usually accepted. WILDSCHÖNAU GABBRO.—[IĪn a communication on this subject, Cathrein’® calls attention to the article of Hatch, already noticed in these notes. He claims that the latter’s hornblende-gabbro and amphibolite are chlorite-gabbro and chlorite-schist, and that there are no proofs of the close relation which that author sup- poses to exist between normal gabbro and serpentine on the one hand and amphibolite and epidote rock on the other.

Pilite-kersan- tite from Spitz on the Donau and pyroxene-amphibolite from Aschauer are also described. In the same article Becke reports the result of a reinvestigation of Schrauf’s kelyphite,' the altera- tion product of pyrope in olivine rocks. This substance, he thinks, is a mixture of a chrome-spinel and a ‘silicate, probably hornblende. The reaction of the olivine on the garnet he rep- resents thus: : Mg,Al,Si,0,. + Mg,SiO, = Al,MgO, + Mg,Si,Qj, rope, in spinel, amphibole. —lIn a letter to the Neues Jahrbuch, F. H.

The same writer* denies the widespread existence of cordierite in Hunga- rian andesites, but finds it in many trachytes. Kolenko® men- tions hornblende pseudomorphs after olivine as characteristic of a metamorphosed olivine diabase from the north shore of Lake Onega, in the Caucasus. The olivine substance is entirely changed into aggregates and crystals of a non-pleochroic hornblende. vathrein® communicates an interesting paper on the altera- fion of garnet in the amphibolites of the Tyrolese Central Alps. Pseudomorphs of epidote, scapolite, oligoclase, horn- blende, saussurite and chlorite are described in detail. The scap- olite substance is intimately mixed with epidote and plagioclase, and the whole is surrounded by a rim of hornblende crystals. In the change to hornblende, crystals of magnetite separate and the excess of silica, magnesia and lime unite to form epidote. MiscELLANEous.—lIn a discussion concerning the conduct of the zeolites with reference to their water constituent, C. Bodewig* shows that the loss of weight which phacolite suffers over CaCl, must be due to loss of water of crystallization and not to loss of hygro- scopic water. He also contests the idea of Jannasch® that every desiccating agent abstracts a certain definite amount of water from ese minerals and consequently some of the loss over CaCl, may be due to loss of water of combination.

[February, of Naumann’s “Elemente der Mineralogie ™ has just appeared. The work has been newly revised and brought up to date by Dr. Ferdinand Zirkel, who has undertaken this duty since the death + of Naumann in 1873. The new edition contains about fifty pages and thirty-three wood-cuts, more than the eleventh (1881). The chemical formulz used have all been recalculated and the recent advances in the field of optical and physical mineralogy ave been incorporated in the body of the work, so that the new book is the most complete and satisfactory treatise on general mineralogy published in any language. An abstract from the forthcoming “ Mineral Resources of the United States, Calendar Years 1883 and 1884,” has just been received. It is entitled “Precious Stones.” The author is G. F. Kuntz. The paper treats of the production of precious stones in the United States in 1883 and 1884 and their importation, The total value of pre- cious stones found during 1884 was $82,975, including $800 topaz was taken out. The reports in the newspapers of remark- able finds have all been investigated and have proven to be unre- liable. The great “ Georgia Marvel” or “ Blue Ridge Sapphire,” for instance, which was supposed to be a sapphire worth $50,000, turned out to be nothing but a “piece of rolled blue bottle- glass.” The paper is interesting as showing just how far we can rely upon our own resources to supply us with ornamental stones. The author also mentions several uses to which domestic material can be applied with fine effect. : BOTANY.’ Can VARIETIES OF Apples BE DISTINGUISHED BY THEIR FLOW- ERS.—To a botanist this may seem like a queer question, capable only of an answer in the affirmative, but pomologists have quite universally held to the opposite view. awa like the fol- lowing, ewe be made from our most eminent writers of pomo- " o a are partially classified by the size and color of the petals, but in all the other fruits, as in apples, pears, plums, cher- ries, etc., the flowers vary but slightly in form and color?” ~~ Another says: “ Little difference exists in the flowers.” a te der Mineralogie. 951 ills., ipzig, ) Lipa tno, 95 7 peg Wein Eageimann * Edited by Professor CHARLES E. Bessey, Lincoln, Nebraska. 1886. | Botany. 163 At a meeting of the Michigan State Pomological (now Horti- cultural) Society, held in 1873, the writer presented a paper on .this subject in which he accurately described quite a number of kinds of apples by the flowers. To the pomologist the term “ flower ” means the showy petals; to the botanist it means calyx, corolla, stamens and pistils. These floral characters are as constant and reliable for distinguishing varieties as are those characters of the fruit which are usually employed. In apples the points of the calyx vary in breadth, size and in other particulars. The petals vary in size and shape in different varieties, and some in color. Not very much was made of the. stamens, but the styles and stipe furnish excellent characters. Dr. Hogg, of England, pointed out the value of the shape of the calyx-tube and the position of the stamens on the inside of the tube, but in our American apples, at any;rate, these points are not so reliable as are those pertaining to the stipe and styles. In 1879, at the Rochester meeting of the American Pomologi- cal Society, I presented an illustrated paper on the classification of apples, in which the peculiarities of the flowers formed an im- portant part. Many flowers were examined from different trees in various localities. Over a hundred varieties have been ex- amined. I have since that time frequently called the attention of my Students to this subject, and last spring (in 1885) suggested it to one of our graduates, Mr. W. L. Snyder. I have had some o his drawings carefully copied for your use. Unfortunately in these cases the petals were not drawn, but a glance at the lobes of the calyx, and especially a close examina- - tion and comparison of the stipes and styles will show a great a in the length, breadth, hairiness and other points of the es. _ At the Boston meeting of the American Pomological Society, in 1881, I showed that a similar difference exists in the lobes of the calyx, the shape and size of the petals of pears, but in these flowers pe ipt is very short or wanting. The styles vary as do of apples. Mr. Snyder also made some notes and drawings of the flowers and inflorescence of some of our cultivated varieties of strawber- Pda are quite as marked as those here shown for the flowers of apples. In case of apples probably 3000 or more varieties have been cribed by the fruit alone. It is needless to say that with a variety of soils and climates it is next to impossible to define so many in a manner which shall be at all satisfactory. “e A similar difficulty exists in our sorts of pears, peaches, plums, , Strawberries, raspberries and a myriad of cultivated grains vegetables [exactly how many I do not know.

How are they usually described? Mainly by the time of fruiting, size and color of pod and the peculiarities of the seeds. e are living in a time when there is much said about the difficulty of describing so many varieties of cultivated plants, It seems to me the correct solution of this problem is here sug- gested: Instead of describing lettuce and turnips and onions by the shape of leaf and head, color and shape of root, or the color and shape of bulb respectively, let the inflorescence and flowers be carefully examined and a clear record made of a// the charac- ters which prove to be most reliable. The time has come for more careful work in this direction. The skill of a good botanist should be joined to that of a good horticulturist.— W. F. Beal, Agricultural College, Mich. FORMATION OF STARCH IN THE LEAVES OF THE VinE.—Sig. Cuboni has made a series of observations (Rivista di Viticoltura ed Enologia Italiana, 1885) on the formation of starch in leaves of the vine. In March and April, when the leaves are first formed, amonth old. It depends, however, to a certain extent on the maturity of the chlorophyll-grains. In a leaf containing no starch at the outset, abundance was found after an hour’s exposure to the direct action of the sun- light ; and the maximum quantity was obtained by two hours’ Although the youngest leaves are unable to form starch, the maximum development is not obtained by the lowest leaves on a branch, but by those on the middlemost nodes; on a branch con- taining sixteen leaves, by those from the seventh to the eleventh, . the lowest showing less than half the maximum power of pro- duction. If an annular incision is made above and below a leaf, sepa- rating the elements of the soft bast, the starch in the leaf is not and transformed in the dark ; but if a similar incision is made only below, or only above the leaf, the ordinary process is not disturbed ;. and this is also the case if a leaf separated by an incision on both sides has a panicle of fruit or flowers opposite it on the same node. No starch is formed if the leaves are etio- -a or attacked by Peronospora viticola.— Four. Royal Mic. Society, VOL, XX.—NO. 11, co 12 166 General Notes. [February, THE PRopucTION OF MALE AND FEMALE P ants. — Recent observations and experiments by Hoffman (Bot. Zeit., 1885) con-* firm the view hitherto held by some biologists that the produc- tion of the male organism is due to insufficient nutrition. In Lychnis diurna and vespertina, Valeriana dioica, Mercurialis annua, Rumex acetosella, Spinacia oleracea and Cannabis sativa dense sowing increased the amount of male plants. Pear BLIGHT BACTERIA AND THE HorTICULTuRISTS.—AlIthough to the mind trained in the logic of investigation there can be no doubt as to the cause of pear blight, there are yet some horticul- turists who do not feel convinced. With them the facts—plain facts—brought out by Mr. Arthur at Ann Arbor, and reproduced in popular form in the December NATURALIST, are spoken of as the “ Bacterian theory of pear blight,” when as a matter of fact there was no “theory” in the presentation. As was remarked by one of the auditors at Ann Arbor, Mr. Arthur’s paper amounted to a demonstration, and as a demonstration it must be accepted. One may as well attempt to controvert a demonstra- tion in geometry as to attempt it in this case. We have observed two principal varieties of denials, and both illustrate the fact that the mind untrained in the methods of scien- tific reasoning is most incredulous of demonstrations, and most credulous of unproved assertions. (1) It is held on the one hand that the bacteria observed are an accompaniment and not the cause of the disease, and this in face of the fact that all of Mr. Arthur's investigations were directed to this very point, Professor Burrill having long ago shown the presence of bacteria beyond a doubt. Our horticultural friends must bear in mind that Mr. Arthur's work was not to find whether bacteria ave present in pear blight. Of that almost any one who has access to a microscope can sat- isfy himself with but little labor. He undertook the solution of the very matter which is now brought up so calmly, innocently and confidently. And he made no announcement until the dem- onstration was reached. Let our friends read the testimony can- didly and they will be fully satisfied upon this point. (2) It is held by another class of disbelievers that what Pro- fessor Burrill and Mr. Arthur have been working upon is a kin ‘of blight which is quite distinct from the real Simon-Pure blight which works such havoc in the orchards. That is, we have here an attempt to diagnose off-hand, out of sight and hundreds of miles away, the disease to which two trained men gave years of close personal study. But science is patient, and no doubt the next work of Mr. Arthur will be the study of cases of this so-called other kind of blight. It will then be interesting to know what new line defense will be set up by those who “do not believe in the bac- terian theory of blight.” i BotanicaL News. — Late numbers of the Botanische Zeitung contain articles as follows: The pith rays of the Coniferæ, by A- 1886. } Botany. 167 Kleeberg; The formation and transportation of carbohydrates in foliage leaves, by A.

Being transferred to a cage provided with earth, they at once buried themselves, but came out at night to feed. They continued this life for perhaps a fortnight, when they gradually left off feed- ing. Just when pupation occurred it was impossible to tell, as the larvee remained in the ground some time in a torpid state before this change took place, and at this time many of them died. The pupæ, which had been reserved for description, were unfortunately destroyed by mice. They were of a dark shining brown color, rather thick and blunt at the anal extremity, and somewhat flattened at the thorax. The molts emerged from the 20th to the 30th of September, some two months or more after pupation probably took place.—Howard L. Clark, Provi- dence, R. L. MORPHOLOGY OF LepipoprerA.—In the Zeitschrift für Wissen. Žoologie for Oct. 27, N. Cholodkovsky states that it has been found that three species of the Linnæan genus Tinea possess only two Malpighian vessels, a most unexpected phenomenon, and until the present time an isolated fact in insect anatomy, unless we except certain Coccide, which have been found by Leydig and Mark to also possess but two Malpighian tubes. On the other hand, Cholodkovsky has found in Galleria mellon- ella Linn. a very peculiar form of Malpighian vessel, which up to now has been described in no other insects, and which only finds its parallel among the Arachnida. This example is an illustration, he says, of the utter incompleteness of our present knowledge o insect anatomy. In several female NMematois metallicus Pod. Cholodskovsky found that each ovary consisted of not less than twelve, and in one case twenty egg-tubes. The number of egg-tubes in Lepi- doptera generally is four. There is only a single known excep- tion to this rule. Dr. Alexander Brandt in 1876 discovered that Psyche helix possessed on each side six egg-tubes, while Profes- sor Ed. Brandt stated verbally that Sesia scolitformis possesses fourteen egg-tubes. Cholodkovsky then describes the external and internal geni- — talia of Nematois, and, in describing the ovipositor, refers to the much more highly organized ovipositor of the common house- moth (Tineola biselliella). All Lepidoptera possess two compound testes, which in the greater number are united by a complicated set of coverings into an unpaired organ. Since each testis consists of four seminal fol- licles they are in every respect homologous with the egg-tubes of the females. There is anatomically a complete and clear homology between the female and male sexual glands of the Lepidoptera. is fact is not without significance in the morphology of Lepi- doptera, especially since it becomes a link connecting the Phry- 170 General Notes.

He also finds a small chitinous ring at the end of the abdomen -of the male, which he regards as the rudiment of a tenth abdomi- nal segment. Cholodkovsky regards these cases of the occurrence of primi- tive characters in Lepidoptera as instances of a periodical atavism, or retrogression to the most primitive form of anatomical struc- ture. In conclusion, the author with good reason finds fault with the term “ Microlepidoptera,” thinking it artificial and absurd to classify animals by their size alone. Friicuts oF Locusts at San Luis Potosi, Mexico, 1885.—We have received the following description of a flight of locusts at San Luis Potosi, Mexico, in a letter dated June 9, 1885, from Dr. G. Barrceta, well known as one of the most cultivated scien- tists in Mexico: “On the 31st May a cloud of grasshoppers came from the N. E. and S. E. to this city, and remained about three hours, leaving only on account of rockets, the ringing of bells and every kind of noise. Never before in this century have locusts invaded this land. By this mail I send a tin box with samples. Those in white paper reached a year ago certain places of the state, 150 miles east of this city, and at the altitude of 3000 feet above the sea. They were collected in Rioverde, aud then the cloud took its way to the southeast. In the aforesaid box, those in blue paper belong to the invading swarm which visited the city on May 31st. I found no difference between them, and suppose them to be the progeny of the swarms noticed in 1884, or, at least, the same species,” Unfortunately the specimens were never received, so that we are unable to give the name of the species.— A. S. Packard. LONGEVITY or Ants.—Not the least interesting fact which has resulted from my observations has been the unexpected longevity of these interesting insects. The general opinion used to be that they lived for a single season, like wasps. Aristotle long ago _ stated that queen-bees live for six and some even seven years. Bevan, however, observes that “the notions of both ancients and moderns upon the subject have been purely conjectural. Indeed, it appears to be somewhat doubtful whether the length of life which the former seem to have attributed to individual bees was not meant to apply to the existence of each bee-community.” The nests, however, which I have devised have enabled me to throw considerable light on this question, The queen ants are SO easily distinguished from the workers that they can be at once identified, while, if a nest be taken in which there is no queen, we can satisfy ourselves as to the workers ; because, though it is true 1886.] Entomology. 171 that workers do sometimes lay eggs, those eggs invariably pro- duce male ants. Hence, in such a case, the duration of the nest gives us the age of the workers; at least they cannot be younger, though, of course, they may be older. In this way I have kept workers of Lasius niger and Formica fusca for more than seven years, But, what is more remarkable still, I have now two queens of the latter species which I have kept ever since 1874, and which, as they were then full-grown, must be now nearly twelve years old. They laid fertile eggs again this year, a fact the inter- est of which physiologists will recognize. Although a little stiff in the joints, and less active than they once were, they are still strong and well, and I hope I may still keep them in health for some time to come,—.Sir John Lubbock in Contemporary Review for Nov.

We would add, that the thysanurous characters do not seem to be well marked, while it is possible that the specimens, though numerous, had lost their heads. In Dr. Agassiz’ report as curator of the Museum of Comparative Zodlogy, it is stated that the museum has received from the Peabody Academy of Science at Salem the most import- ant collection of insects ever added to the museum.

It contains a large proportion of Packard’s types, including those of his monograph of geometrid moths, of which only four species are wanting, and nine described by him from specimens belonging to other entomologists. It also comprises types of Mr. Grote and the late V. T. Chambers, as well as types of Zeller, Staudinger, Foerster, Walker, etc. 172 General Notes. [February ZOOLOGY, ANTIDOTE TO THE ScorRPION’s Stinc.—Already an antidote has been discovered to the sting of scorpions, which, although rarely fatal, is extremely painful, while the poison is closely allied to that of the venomous snakes. Mr. A. M. Markham, of the Indian Civil Service, has written to one of the Indian papers calling attention to the fact that the root of? Achyranthes aspera, known popularly as chirchirra, affords almost instantaneous relief from the pain caused by the sting of a scorpion. The plant is very common everywhere in India, and is one of those whose clinging burrs are such a nuisance on one’s legs when out shooting. The root, macerated in water, is applied to the part stung, and a small quan- tity is drunk in water. If this be done quickly, there is absolutely no pain half an hour or so after the sting, instead of the twelve to twenty-four hours of intense suffering which follow an untreat- ed sting —London Standard.

The num- ber of Pontic species of Decapods has been increased by twenty, reaching thus forty-eight species, with numerous varieties, though it will probably be greater when the depths of the Black sea have been better explored. The results of this work are numerous and interesting. The species offer altogether a very great variety of o he Black sea contains the local forms of Mediterranean varieties, while in the Celtic region are found the local forms of other varieties.

In Casco bay, Maine, the lobster molted during the second and third week of July. According to the lobster-fishermen, the creature molts but once a year, and as con- firmatory of this the lobsters we saw were in several cases covered with patches of polyzoans, with large barnacles, mussels, etc., which could not have been of the present year’s growth. Shortly before the animal molts the parts between the segments are much swollen, and have a livid color. Meanwhile the inner side of the flattened basal joints (3-5) of the large claws become soft, the lime on the crust partly disappearing, leaving an irregu- lar oval solid portion; in this way the contents of the large hand or claw can be drawn through the basal portion of the limb. The first step in the ecdysis is the splitting or partial separation of the two halves of the carapace; it may entirely separate poste- riorly, or the two halves remain together, and the animal withdraws its body out of the sutures between the thorax and first abdominal segment, The integument of the legs is molted last, and when owing to rough handling, the process is delayed, the extremities of the legs slough off. The entire integument, with all the appendages of the head,thorax, and the abdomen are molted as a whole, but the abdominal legs are molted before the thoracic ones. I have found all the parts of the crust con- nected, and floating in the “lobster car,” even including the lining of the proventricle or stomach, and the apodemes of the head and thorax. After the molt the soft and flabby lobster lies nearly motionless, occasionally, if disturbed, giving a flap wit its “tail.” It remains inactive for nearly or quite a week, until the new crust becomes hard. am convinced from my observations that the deformities in the big claws as well as other parts occur at the time of molt- ing; as after disturbing the symmetry of the claws in our speci- men, the deformity persisted —A. S. Packard. Tue Orpesr Tarsus (Archegosaurus).—The Neues Jahrbuch für Mineralogie, Jahrgang 1861, pp. 294-300, contains a paper by Professor Quenstedt, of Tiibingen: “ Bemerkungen zum Arche- gosaurus.” On Plate 111, connected with that article, a nearly entire hind-foot of Archegosaurus is figured (fig. 6). The tarsals of this foot are preserved in their original position, and it is of very high interest ; but, strange to say, this figure of Archegosau- rus has been entirely overlooked, and is never mentioned in any Paper relating to the tarsus of vertebrates. Professor Quenstedt believes that there are ten or twelve tarsal ones preserved, The question now is, What are the homologies of these bones ? On the whole, the hind-foot recalls very much that of Crypto- branchus and Menopoma. One or perhaps two bones are con- 174 General Notes. [February, nected with the tibia; if there is only one, this must be the tibiale. Two elements are attached to the fibula—the intermedium and the fibulare. Four metatarsals are preserved, but it is pos- sible that there were five. Each of the four metatarsals is sup- ported by one tarsal bone. Between the four bones of the distal series and those of the proximal one there are to be seen four additional bones, The inner one I consider the tarsale,, belong- ing to the first digit not preserved. The remaining three bones must be considered as three central bones. If two bones are connected with the tibia, the outer one repre- sents the tibiale, the other one a centrale, reaching the tibia in the same way as in Salamandrella (Wiedersheim). In this case, we have four central bones. Between the fibulare and tarsale, there is a large space without any bones. There is little doubt, I think, that there existed a sixth tarsal bone in the distal series, as in Cryptobranchus, remaining cartilaginous, and therefore not pre- served, Wiedersheim’ described three central bones in the tarsus of the Axolotl; fig. 8, pl. xxx, comes nearest to the condition in Arche- gosaurus, There are two explanations of the morphology of the tarsus in Archegosaurus, if there are five digits : 1.

In no living reptile have intercentra been described, so far as I know, in that part of the column, excepting in Sphenodon (Hatteria)? I find them also in Gecko verticillatus Laur. (G. verus Gray). In these forms intercentra are developed between a// vertebre. It is probable that the same elements will be found in the other Geckonidze and in the amphiccelian Uroplates, the only genus of the family Uroplati Lumbar intercentra in the Mammalia are first mentioned by Owen’ in the mole.

Baur, Yale College Mus., New Haven, Conn., Dec. 19, 1885, THE INTERCENTRUM IN SPHENODON.'—Researches into the em- bryology of the Urodela and Anura have not yet brought to light any traces of the rhachitomous structure; a condition of things which is probably due to ccenogeny or falsification of the embry- onic record—a phenomenon which is not uncommon. There can be no doubt, however, that the entire record was presented in the embryonic history of Permian land Vertebrata, and for a long period subsequently, but that the rhachitomous stage has: been, with the true centrum, lost from the batrachian line at least. The only existing reptile which could be expected to show important traces of the ancestral, or embolomerous stage, is Sphenodon. This genus, as is well known, is the living representative of the order Rhynchocephalia, the nearest order to the Theromorpha. Having fortunately a specimen in alcohol, presented to me by Dr. Hector, the able director of the Geological Survey of New Zealand, I examined the caudal vertebre to determine the connections of the chevron bones. I find these to be attached, not principally in press. The centra differ much from those of Cricotus in their form, resembling in outline those of the Pelycosauria. They however have the vertical median partial suture seen also in the Lacertilia, as already described by Günther. The caudal vertebra are so gradually modified as we followed them forwards, however, as to make it probable that these halves do not represent any of the elements of the rhachitomous column besides the true centrum. _l add that there is probably a hypocentrum pleurale in the cer- vical region of the rhachitomous Eryops. They become ossified early with the posterior side of the intercentrum in front of m.—. . Cope.

In other families the calcar was adjoined to the calcaneum at the outer side and near the proximal end. The astragalus and calcaneum were nearly of the same size in most forms, the calcaneum being the larger. In the aberrant form Rhynchonycteris the astragalus was nearly twice the length of the calcaneum. I have appended a few diagram- matic sketches of the tarsus. he method employed in studying the tarsus consisted in re- moving all the soft parts of the foot, immersing in absolute alco- hol, transferring to oil of cloves and mounting on a glass slide. A low power of the microscope resolves all the essential structures. —Harrison Allen. RANGE OF THE AMERICAN Brson.—Late issues of the St. Paul Pioneer Press report : “Reliable cowboys just arrived in Miles City, Mont., report that at the Lower Musselshell round-up they saw a fresh trail of about 100 buffalo on the head of the Big Porcupine last week, and had seen twelve head a few days before.

EMBRYOLOGY .* _ THE ORIGIN oF THE AmNion.—The purpose of the present note is to point out some of the mechanical conditions and causes which have been competent, in the course of the development of development, to bring about the formation of the amnion. embryological writer, as far as I am aware, has ever attempted to trace the amnion to the part in the embryos of anamniated forms which led up to its development in the amniated ones. Balfour said, that “it does not seem possible to derive it from any pre- existing organ” (Comp. Embryol., 11, 256). And he says further (op. cit., 257): “The main difficulty is the early development of the head-fold of the amnion.” Balfour's view, that it is developed ` part passu with the outgrowth of the allantois, is utterly inade- quate to explain the genesis of the amnion of insects or that of Peripatus edwardsii and P. torquatus, for in them no allantois is formed. His hypothesis also breaks down in the light of the eae researches of Selenka on the inversion of the layers in e a. _ A comparison of the longitudinal, vertical, diagrammatic sec- tions, figures A and B, of an osseous fish-egg and a mammalian ovum respectively, will conclusively show that the somatopleure s, in A, is the exact homo- ‘Edited by JoHN A. RYDER, Smithsonian Institution, Washington, D. C. ~- 180 General Notes. [February, between the yolk y and the somatopleure, leaving the coelomic space c, which has been derived directly in the osseous fish embryo from the cleavage cavity of the egg, We thus find that the preexisting structure, from which the amniotic folds are formed in the higher types, is already present in the embryos of osseous fishes. The next important point to demonstrate is, at what grade in the phylum of the Chordata traces of amniotic folds first appear, and whether such rudiments of an amnion are also found in the embryos of osseous fishes. Glancing at 4, it will be seen that there are rudimentary amni- otic head and tail folds developed at a and a’, and that we, there- fore, have traces of an amnion appearing for the first time in embryos of the grade of osseous fishes. This is not universal, however, for it is found that in species in which the zona radiata z does not closely invest the ovum, the embryo Æ is not pressed down into the vitellus, so as to raise the somatopleure s into a fold or duplicature around the ends and along the sides of the embryo. The zona invests the ovum more or less closely in almost all Teleosts, but in a few, Alosa, for example, it does not, and in this species no traces of amniotic folds are ever developed, The embryo is differently conditioned in those eggs with the zona fitting closely around the ovum from those in which there either in the form of a rigid outer egg-shell, zona radiata z, or decidua reflexa dr, or even the walls of the uterine cavity itself, supposing, of course, that a large vesicular blastoderm con- taining yolk has been formed by epiboly. The gap between the truly epicyemate embryo, as seen in Alosa, and the endocyemate embryo of the Paratheria and Eutheria is, therefore, partly bridged by the presence of a rudi- mentary amnion, or amniotic folds in many teleostean embryos just prior to their escape from the eggs, or where the zona is ruptured. When this occurs the-amniotic folds vanish, as in the - embryos of many of the Salmonide, for example, anda closed amni- 1886.] Embryology. 181 otic sack is never formed, because, in the first place, the intra-oval period of development does not last long enough; nor,in the second place, is it possible, owing to the comparative small size of the yolk, and the rapid growth of the embryo, for the latter to become bodily invaginated into the blastodermic vesicle, which is filled with yolk. The amniotic folds can, therefore, not meet upon the middle line of the back, and coalesce, as they do in the higher endocyemate forms. The development of a transient amniotic head-fold of greater width and in advance of the side and tail folds, is also prevented by the absence of a strongly marked cranial flexure in the embryos of Teleosts. The mechanical effect of the gradual development of the cranial flexure in exaggerating the development of the amniotic head- fold in the Chordata, will be best appreciated by a glance at diagrams 1, 11, 111, and Iv, representing respectively the brain of an acraniate, a marsipobranch, an elasmo- branch anda mammal. With the increase ©——————= I in the volume and area of the cerebral cortex, which occurs mainly on the dorsal i arate m and lateral aspects of the anterior end of the neurula, the acceleration of growth of Ir the brain substance also occurs on those JE aspects, and a downward flexure of the floor of the brain necessarily takes place. zë The rapid enlargement of the cephalic end of the embryo of an endocyemate, eutherian or paratherian form, and the rapid or precocious development of the cranial flexure, would naturally, in such a type, tend to cause the amni- otic head-fold to be developed earlier and to a greater extent than the tail-fold, as is shown in Fig. B, at a. In the eutherian types, with inverted germinal layers, an amni- otic head-fold of the kind developed in normal forms is never rmed, because the cavity of the true amnion in the former is developed by the vacuolization or the formation of a cavity or cavities in the solid epiblastic mass, and not by invagination. In the Tracheates possessing an amnion there is no cephalic flexure, and the part of the amnion which is first developed in the most Pronounced manner is often the tail-fold, due apparently to the ingrowth of the caudal end of the embryo into an involution of ê blastoderm, confined in a rigid egg-envelope, the involution being thrust into the yolk. Later, with the growth and encroach- ment of the head-end of the embryo upon the yolk, the abdomen is again everted in some cases from its amniotic sack. In Peripatus edwardsii, according to Von Kennel, cleavage is total, the devel- PAON is viviparous and intra-uterine, a hollow blastula is ormed, the embryonic area at one pole of the blastula is invagi- nated into the latter, so that the ventral surface of the embryo is VOL, XX.—NO. IL “7 182 General Notes. [February, directed towards the roof of the amniotic cavity, the reverse of the eutherian embryo. An umbilical stalk is also formed, which springs from the dorsal surface of the embryo and passes toa partially zonary placenta, disposed in relation to the uterine walls in exactly the same way as that seen in the embryo of Carnivora. If we now regard the dorsal surface of the embryo of Peripatus edwardsti as homologous with the ventral surface of the embryos of Carnivora, the resemblance between the modes of development of these two types becomes still more startling. While it is manifestly absurd to even attempt to suppose, on the strength of these resemblances, that there could be any genetic affiliation between the Carnivora and Malacopoda, the only way out of the difficulty seems to be to suppose that the similar methods of development of the two arose in response to the similar conditions which environ the ovum during its early stages of growth. The differences between Von Kennel and Sedgwick, as to the modes of development of P. edwarasti and P. capensis, it seems to me, may be readily understood and reconciled when it is consid- ered that the first is holoblastic and endocyemate, while in the latter the egg is meroblastic, and apparently undergoes an epicy- emate process of development. All the data in the foregoing paragraphs unequivocally support the thesis that the amnion has been developed mainly by mechan- ical means and conditions. The rigid zona of the epicyemate teleostean embryo, as shown in Fig. A, in which the yolk y is a positive quantity, is repre sented by the maternal envelope dr in Fig. B, in which the yolk, as such, is absent. The gap between the condition of A and that of the types with apparently inverted germinal layers, so complete- ly elucidated by Selenka, is a wide one; yet it seems easy to pass from the primitive condition of A to that of the extremest form, viz, the guinea-pig; if the rabbit, mole (Heape), the vole (Kup- ffer), and the mouse and rat (Selenka), are considered as inter- mediary steps. Socomplete or extreme has been the invagination of the embryonic mass or area in these forms that, in the extrem- est type, the embryo is finally developed at that side or pole of the primitive blastula which is exactly opposite the point where the blastodisk was originally formed, as in normal Eutheria. The way in which this is accomplished is quite remarkable, and may now be described, as the process is a special modification of that by means of which the usual endocyemate condition is brought about. Selenka finds that there is an outer layer of cells, o/, Fig. G, split off from the ectoblast, as first described by Rauber, in the rabbit’s ovum, and which take no direct partin the formation of the embryo. He also finds that upon the further growth of the ovum, after the blastula stage is reached and the germinal area Of disk is developed, the blastula rapidly elongates in the direc 1886. } Eminyology. 183 tion of the diameter extending from the centre of the blastodisk to the opposite pole. By this time the blastula has become adherent to the uterine epithelium through the intermediation of the transitory outer layer of cells, of (Reichert’sche Deckschicht), already mentioned, but the constituent cells of a certain portion of this outer layer, just overlying the germinal disk, as indicafed at s, rapidly proliferate, so as to form a lenticular or columnar thick- ening or mass, constituting what Selenka calls the Zréger, a term which may be anglicized by the word suspensor. This suspensor immediately overlies and pushes the germinal area or mass in- wards before it, down into the hollow cavity of the blastula. The germinal area is either pressed inwards into the hollow blastula, so that it assumes a concave form above, with a cavity between it and the lower surface of the suspensor, as in Arvicola, or the epiblast forms a solid mass, before which the hypoblast is pushed inwards by the ingrowth of the suspensor, so that the blastula assumes the form of an elongated sack, as in the ovum of the rat or the guinea-pig. € process just described is somewhat similar to that of gas- trulation, for the germinal pole of the blastula is pushed down- ward into the sack formed by the hypoblast and outer layer, so that the embryo is finally developed quite at the opposite pole of the elongated blastula, as in the guinea-pig. The steps by which the mode of development of the embryo of the latter came to be established will be much better understood by reference to dia- grams C, D, E, and F, representing four stages of the develop- ment of the rat copied from Selenka! In these figures it will be obvious to the reader that the principal result of the precocious invagination of the embryonic area is to throw the embryo to the Opposite pole of the egg, and to so encroach upon the cavity of the mesenteron, the umbilical vesicle, as to almost obliterate it, as is shown in Fig. The embryo Æ is also bent into a curve, just the reverse of that shown in Fig. 8. The ccelomic space ¢ is also more restricted, and the sinus terminalis s¢,in Fig. F, seems to —S über Entwickelungsfeschichte der Thiere. Drittes Heft. Die Blätter- im Ei der Nagethiere, 4to.

In the ovum of the guinea-pig the obliteration of the umbilical vesicle y is carried still farther than in Fig. F, because the hypo- blastic layer “y’, next to the layer o/, is absent, and the hypoblast lying just under the embryo is brought into immediate contact with the layer o/, thus giving rise to the illusion that a complete inversion of the primary embryonic layers has occurred. I say illusion, because there has been no actual inversion of the primary layers, for the latter have been merely shoved to the opposite pole of the eggs into contact with the layer o/, where embryonic development has proceeded in the normal way, being modified only by the displacement which the germinal area has suffered in relation to the other essential parts of the ovum. It is as if the germinal pole of the blastodermic vesicle had become concave instead of convex, and collapsed inwards against the inside of its lower pole, the walls of which consist of the hypoblast of the inferio? pole of the umbilical vesicle—mesenteron, and the outer layer. he difficulties which Balfour speaks of have, I hope, been satisfactorily cleared away by what has been said above, and a rational and connected hypothesis as to the genesis of the amnion firmly established. I am aware that many objections may be urged against the views here propounded, but I cannot think that ny other view of the case will so satisfactorily reconcile and coordinate the facts involved. To those who takea philosophical view of such subjects, it will be obvious that the deductions here reached give but little countenance to the idea that amniotic char- acters can be always profitably used in taxonomy, at least, not until the forces which have led to their development are better understood. On the theory of the development of development, the extreme modification of the amnion of some of the Rodentia would cause the latter to take higher rank than the Primates, because, as shown in Fig. F, the primary amniotic cavity becomes divided, and a relatively large false amniotic cavity f remains just under the suspensor s, and shut off from the true amniotic cavity ac by the intervening serous envelope se, the coelomic space ¢, an the somatopleural roof of ac. Such reasoning, however, is obvi- ously not legitimate in the light of the above mechanical hypoth- esis of the genesis of the amnion me To briefly summarize, we find that the first traces of amniotic folds met with in the embryos of the lower types of Chordata are _ caused by the resistance from without offered to the growth the embryo by a rigid zona radiata. In such types the amniotic folds are transitory, and disappear at the time the zona is ru tured. After a larger yolk has been acquired the embryo undergoes 4 longer period of intra-oval development, so that the period of the persistence of the amniotic folds, produced as before, is prolon MR 1886. | Physiology. 185 With the increase in the size of the embryo, in these large-yolked forms, it is finally thrust down into a saccular involution of the blastoderm, the lips of the opening of which meet over the back of the embryo where they coalesce, the outer limb of the duplica- ture giving rise eventually to the serous envelope, and the inner to the roof of the amniotic cavity. In those types which have the primary layers apparently inverted, the rapid ingrowth of the sus- pensor precociously invaginates the germinal area inwards before the embryo is distinctly developed, so that it is not formed in its usual or normal position. These extreme modifications were not possible until after the loss of the food-yolk, after which a hollow blastodermic vesicle still continued to develop, filled with a thin albuminous or serous fluid instead of a dense yolk material. The tendency of the eutherian ovum to form a large, hollow blasto- dermic vesicle or blastula is doubtless an inheritance transmitted from a paratherian source. The bodily invagination of the whole embryo, and the more or less complete obliteration of the cavity of the umbilical vesicle by the rapid growth of the enlarging amnion, would be readily accomplished in the course of the development of the eutherian ovum.

THE EXISTENCE OF TWO KINDS OF SENSIBILITY TOWARD LIGHT. * 186 General Notes. [ February, to the area outside the fovea centralis. This increase of sensi- bility is proportionately greater toward the more refrangible rays. This fact affects the tone of colors, and on account of it the lumi- nosity of (the more refrangible ?) colors is increased at the expense of their saturation. The reader may be reminded, as an interest- ing confirmation of this view that, when alternate circles, painted blue and red, are looked at in obscurity, the former appear lumi- nous and the latter black. Visual purple is bleached by light and is regenerated under the influence of the pigmentary layer of the retina in the dark. In these facts we have an explanation of the varied sensibility toward light of different intensities — Comptes Rendus, 1885, p. 821. concerning the supply of blood to nerve ganglion cells. In his researches on the blood-vessels of the spinal cord, the author found that the richness in capillaries was directly proportional to the number of nerve-cells. His more special investigations of this relation were made on the intervertebral ganglia taken from injected animals. The nerve-cells composing these ganglia are each inclosed in a connective-tissue capsule, lined by flattened cells and having two tubular prolongations from it. The nerve- cell itself is inclosed in a special sac of flattened cells and pos- sesses two prolongations which reach out into those of the surrounding connective-tissue capsule. Between the latter cap- sule and the cell is a rather roomy space, and there is also a much narrower one between the substance of the cell and its own epi- thelial covering. The arterial blood enters by an afferent vessel into the pericellular space and leaves it by a much narrower efferent vessel. The blood thus surrounds the cell under pressure and its liquid portions pass actively by osmosis into the substance of the cell itself, in the centre of which they are received by an empty space. This empty space is nothing else than what has so long been regarded as the nucleus of the cell. This space belongs to the venous system with which it is in connection by a minute vessel having its own proper wall. A solid body, hitherto called the nucleolus, is suspended fixed in the centre of the nuclear cavity —Comptes Rendus, 1885, p. 826. PasTEUR’s METHOD FOR THE PREVENTION oF HypROPHOBIA.— In the Comptes Rendus for October, 1885, is the latest report of Pasteur’s experiments upon the prophylaxis of hydrophobia. The following is an outline of his procedure: When a small particle of the spinal cord of a dog dead from rabies (moelle rabigue) is placed under the dura mater of a rabbit the animal always falls ‘a victim to hydrophobia after a period of incubation which lasts some fifteen days. When virus from the first rabbit is transferred in the same way to a second and, after the period of incubation is ` 1886.] Fhystology. 187 passed, that from the second to a third rabbit and so on, the dura- tion of the period of incubation becomes more and more reduced. After the successive inoculation of twenty to twenty-five rabbits, the time of incubation is reduced to some eight days, and the incubation period remains of this length throughout a further series of twenty to twenty-five successive inoculations; then the time of incubation is shortened to seven days, which is maintained with remarkable regularity throughout a new series of ninety inoculations. Pieces of the spinal cords of these rabbits induce hydrophobia with constant virulence. When the diseased cord is detached from a rabbit under the strictest precautions against contamination by impurities, and is suspended in a flask, the air of which is kept dry by caustic potash on the bottom, its viru- lence gradually disappears and may become wholly lost. The virulence fails somewhat more slowly the larger the piece of which was maintained dry. As stated above, the virulence of each specimen diminished progressively with its exposure. Ster- ilized bouillon was inoculated with a small portion of cord which had been exposed for such a time that the loss of its virulence was certain, and a small syringe full was injected under the skin of a og. On each day following a similar operation was performed, using, however, at each injection, spinal cord which had been exposed for a shorter time and which possessed, therefore, pro- gressively increasing virulence. When this procedure had been repeated until the dog had received an injection of virus which had been exposed to dry air only one or two days, the animal was found to be perfectly protected against hydrophobia, and might with impunity be inoculated with the strongest virus. Fifty dogs were thus made resistant to the disease without a single failure, besides which a number were successfully inocu- lated after having been bitten by rabid animals. A child which ad been lacerated by a mad dog two days before and whose wounds had been cauterized with carbolic acid two hours after € injury, was brought to Pasteur for treatment. The method pursued was similar to that described, and the final inoculation was with virus more virulent than that of ordinary rabies. Three months and three weeks after the accident the child was still well. Pasteur explains his results by supposing that the products formed by the vital activity of the germs of the disease are poison- 188 General Notes. [February, PSYCHOLOGY. Sir J. LUBBOCK ON THE INTELLIGENCE OF THE Doc.—Before a crowded sitting of the biological section of the British Association, Sir John Lubbock read a paper in which he gave some interesting notes on the intelligence of the dog. The man and the dog, he said, have lived together in more or less intimate association for many thousands of years, and yet it must be confessed that they know comparatively little of one another. That the dog is a loyal, true, and affectionate friend must be gratefully admitted, but when we come to consider the psychical nature of the animal, the limits of our knowledge are almost immediately reached. I have else- where suggested that this arises very much from the fact that hitherto we have tried to teach animals rather than to learn from them—to convey our ideas to them rather than to devise any lan- guage or code of signals by means of which they might commu- nicate theirs to us. The former may be more important from a utilitarian point of view, though even this is questionable, but psy- chologically it is far less interesting. Under these circumstances, it occured to me whether some such system as that followed with deaf-mutes, and especially by Dr. Howe with Laura Bridgman, might not prove very instructive if adapted to the case of dogs. I have tried this in a small way with a black poodle named Van. » I took two pieces of card-board, about ten inches by three inches, and on one of them printed in large letters the word “ food,” leav- ing the other blank. I then placed two cards over two saucers, and in the one under the “food” card put a little bread and milk which Van, after having his attention called to the card, was allowed to eat. This was repeated over and over again till he had had enough. In about ten days he began to distinguish between the two cards. I then put them on the floor and made him bring them to me, which he did readily enough, When he brought the plain card I simply threw it back, while when he brought the “food” card I gave him a piece of bread, and in about a month he had pretty well learned to realize the difference. I then had some other cards printed with the words “ out,” “ tea,” “ bone,” “ water,” spelt phonetically so as not to trouble him by our intri- cate spelling, and a certain number also with words to which I 1886. ] Psychology. 189 dog recognize them by scent. They were all alike, and all con- tinually handled by us. Still I did not trust to that alone, but had a number printed for each word. When for instance, he brought a card with “food” on it, we did not put down the same identical card, but another bearing the same word ; when he had brought that a third, then a fourth, and soon. For a single meal, there- fore, eighteen or twenty cards would be used, so that he evidently is not guided by scent. Noone who has seen him look down a row of cards and pick up the one he wanted could, I think, doubt that in bringing a card he feels he is making a request, and that he can not only distinguish one card from another, but also asso- ciate the word and the object. This is, of course, only a begin- Still, in such a case, one ought not to wish for one result more an another, as of course the object of all such experiments 1$ 190 General Notes. [ February, merely to elicit the truth, and our result in the present case, though negative, is very interesting. I do not, however, regard it as by any means conclusive, and should be glad to see it re- peated. If the result proved to be the same, it would certainly imply very little power of combining even extremely simple ideas. I then endeavored to get some insight into the arithmetical condi- tion of the dog’s mind. On this subject I have been able to find but little in any of the standard works on the intelligence of ani- mals. Considering, however, the very limited powers of savage men in this respect—that no Australian language, for instance, contains numerals even up to four, no Australian being able to count his own fingers even on one hand—we cannot be surprised if other animals have made but little progress. Still, it is surpris- ing that so little attention should have been directed to this sub- ject. Leroy, who, though he expresses the opinion that “the na- ture of the soul of animals is unimportant,’ was an excellent observer, mentions a case in which a man was anxious to shoot a crow. “ To deceive this suspicious bird, the plan was hit upon of sending two men to the wash-house, one of whom passed on, while the other remained; but the crow counted and kept her dis- tance. The next day three went, and again she perceived that only two retired. In fine, it was found necessary to send five or six men to the watch-house to put her out in her calculation. The crow, thinking that this number of men had passed by, lost no time in returning.” From this he inferred that crows could count up to four. Lichtenberg mentioned a nightingale which was said to count up to three. Every day he gave it three meal- worms, one ata time; when it had finished one it returned for another, but after the third it knew that the feast was over. o not find that any of the recent works on the intelligence of ant- mals, either Buchner, or Peitz or Romanes in either of his books, give any additional evidence on this part of the subject. There are however various scattered notices. There isan amusing and sug- gestive remark in Mr. Galton’s interesting Narrative of an Explorer in Tropical South Africa. After describing the Damara’s weak- ness in calculations, he says: “ Once while I watched a Damara - floundering hopelessly in a calculation on one side of me, I observed Dinah, my spaniel, equally embarrassed on the other; she was overlooking half a dozen of her new-born puppies, which had been removed two or three times from her, and her anxiety was excessive, as she tried ‘to find out if they were all present, or if any were still missing. She kept puzzling and running her eyes over them backwards and forwards, but could not satisfy herself. She evidently had a vague notion O counting, but the figure was too large for her brain. Taking the two as they stood, dog and Damara, the comparison reflected no great honor on the man.” But even if Dinah had been clear on this subject, it might be said that she knew each puppy personal- . 1886.] Psychology. IQI ly, as collies are said to know sheep. The same remark applies generally to animals and their young. Swans, for instance, are said to know directly if one of their cygnets is missing, but it is probable that they know each young bird individually. This ex- planation applies with less force to the case of eggs. According to my bird-nesting recollections, which I have refreshed by more recent experience, ifa nest contains four eggs, one may safely be taken; but if two are removed, the bird generally deserts. Here then, it would seem as if we had some reason for supposing that there is sufficient intelligence to distinguish three from four. An interesting consideration rises with reference to the number of the victims allotted to each cell by the solitary wasps. Ammophila considers one large caterpillar of Noctura segetum enough; one species of Eumenes supplies its young with five victims; another ten, fifteen, and even up to twenty-four. The number appears to be constant in each species. How does the insect know when victims are still there or not. How then does she know when she has made up the number twenty-four? Perhaps it will be said that each species feels some mysterious and innate tendency to provide a certain number of victims. This would under no circumstances be any explanation, but it is not in accordance with the facts. In the genus (Eumenes) the males are much smaller than the females. Now, in the hive bees, humble-bees, wasps, and other insects, where such a difference occurs, but where the young are directly fed, it is of course obvious that the quantity can be proportioned to the appetite of the grub. But in insects with the habits of Eumenes and Ammophila the case is different, because the food is stored up once for all. Now, itis evident that if a female grub was supplied with only food enough for a male, she - would starve to death; while ifa male grub were given enough for a female it would have too much. No such waste, however, occurs. In some mysterious manner the mother knows whether the eggs will produce a male or female grub, and apportions the quantity of food accordingly. She does not change the species or size of her prey; but if the egg is male she supplies five, if female ten, victims. Does she count? Certainly this seems very like a commencement of arithmetic. At the same time it would could count; and whether, for instance, it could realize some very simple sum, such as that two and two make four. But when we 192 General Notes. [ February, appear so simple. We tried our dogs by putting a piece of bread before them and prevented them from touching it until we had counted seven. To prevent ourselves from unintentionally giving any indication, we used a metronome (the instrument used for giving time when practicing the pianoforte), and to make the beats more evident we attached a slender rod to the pendulum. It certainly seemed as if our dogs knew when the moment of per- mission had arrived; but their movement of taking the bread was scarcely so definite as to place the matter beyonda doubt. More- over, dogs are so very quick in seizing any indication given them, even unintentionally, that, on the whole, the attempt was not sat- isfactory to my mind. I wasthe more discouraged from continu- ing the experiment in this manner by an account Mr. Huggins gave me of a very intelligent dog belonging to him. A number of cards were placed on the ground numbered respectively I, 2, 3, and so on up to 10. A question is then asked: the square root of 9 or 16, or such a sum as 6 X 52-3. Mr. Huggins pointed consecutively to the cards, and the dog barked when he came to the right one. Now Mr. Huggins did not consciously give the sign, yet so quick was the dog in seizing the slightest indication that he was able to give the correct answer. This 0 servation seems to me of great interest in connection with the so- called “thought reading.” No one, I suppose, will imagine that there was in this case any “thought reading” in the sense in which this word is used by Mr. Bishop and others. Evidently “Kepler” seized upon the slight indication unintentionally given by Mr. Huggins. The observation, however, shows the great difficulty of the subject. I have ventured to bring this question before the section, partly because I shall be so much obliged if any lady or gentle- man present will favor me with any suggestions, and partly in hope of inducing others with more leisure and opportunity to carry on similar observations, which I cannot but think must lead to interesting results— English Mechanic. ANTHROPOLOGY. ! Some Moor POINTS IN American Arcuy#o_ocy.—American archzological science, though continuously gathering strength, is, nevertheless, in a sense still far from manly development. There are celebrated institutions guarding with jealous care objects of _ inestimable worth; preéminent among these, the American Anti- uarian Society (to commence with the oldest), the Smithsonian Institution, the Peabody Museum, the American Museum 0 Natural History, the Davenport Academy of Sciences, as well as those at Cincinnati and St. Louis; there are smaller institutions whose collections are of almost equal value to those above men- tioned, and private museums filled with the richest material. 1 Edited by Prof. Oris T. Mason, National Museum, Washington, D. C. 1886. | Anthropology. 193 In the first place, though these institutions are presided over by men of great ability, there is a deplorable lack of mutual under- standing and uniformity of method among them. There should be between those who hold in trust such vast treasures a better scientific method, a more wholesome comity of intercourse. In short, before we draw inferences we should know what and what kind of material we have in hand. In the second place, investigations have been so increasingly fraught with grand results that some of the first efforts are likely to be ignored or forgotten. There are some points in the history of Squier’s and Davis’ work that have been misunderstood, and as the venerable authors are yet living it would seem a grateful tribute to bear them in mind. The earliest explorations of any great importance in the tumuli of the Ohio valley were made by Dr. Davis, who commenced a series of mound excavations while a student in Kenyon College from 182) to 1833. The result of this first effort was published in some of the college papers. Subsequently, Dr. Davis removed to Chilicothe, in the Scioto valley, celebrated for its earthworks. Here he laid out his plans for the great work which will forever be associated with his name. After ten years of digging, plotting, mapping, and collecting, Dr. Davis was associated with Mr. Squier, and the fruit of their joint labors is the first Smithsonian contribution to knowledge, entitled “ Ancient Monuments of the Mississippi Valley.” When detail and great results. Recently the accuracy of the work done by Squier and Davis has been challenged, and this brings us to another phase of the question. Fully realizing the importance of criticism at any and — all times, we still hold that a very important matter has been overlooked ; it is this: The works of the mound-builders of a particular character or grade have not been compared with works of the same grade by their successors. If some of the best pro- ductions of artistic’handicraft of the present Indians be compared with objects of a similar nature taken from the mounds it is more than doubtful if the superiority of the latter-day Indians can be substantiated. Generally woodcuts are published in this con- nection to show the low condition of the mound-builders’ art. The cuts are copies of casts taken from inferior examples. , every good cabinet in the country. 194 General Notes. [ February, Now it is not a question of argument, but one of things. It is ‘an easy matter to place things side by side, and there would be no question whatever of the superiority of mound-builders’ work over that of every tribe known in historic times any where near the area occupied by them. The pipes and other objects in hard stone should be compared not with pipes in catlinite and soapstone, but with objects in the same material. The same is true of pottery. If we select from any or every collection the best evidences of form and finish and place by the side of them the best specimens of modern work by any tribe east of the Mississippi river there is a hopeless falling off. Now it is but fair to infer that the people who so skilfully wrought in the hardest quartz, who made pottery in every way equal to that of the Pueblos, were not in the same grade as the tented savages whom our ancestors found upon our territory. ut the great, complicated earthworks of the mound-builders, so faithfully examined and reported by the old explorers, furnish the most important evidence of their superiority to their successors. It is true the southern Indians built mounds; but does any one seriously compare the works of the Natchez and Muskoki tribes with those of the mound-builders ? The Iroquois made stockades and enclosures, and Mr. Morgan argued thence the works in Ohio were precisely similar in function. But this opinion cannot stand. In conclusion, we desire to emphasize the importance of that pioneer work, so extended and so valuable to science. There are not many examples of such unselfish devotion. More than one hundred mounds were carefully opened, their contents gathered and arranged, over five hundred embankments and fortifications visited and surveyed in five States, the expense being borne by Dr. Davis. The magnitude and completeness of all this can only be appreciated by examination of “ Ancient Monuments,” an of the treasures collected, now in Blackmore Museum, London.— J. B. Holder.

Blomme to the Congress of Americanists at Copenhagen (1883). The revises came in at so late a day that this elementary grammar could not be inserted in the Compte-rendu of that session, but the secretary ordered it to be struck off in a separate edition, a copy of which is before us. Mr. Blomme has given an historical account of the manu- script in the Compte-rendu, page 365. The grammar is written entirely in the old-fashioned way of the seventeenth and eighteenth centuries, when every missionary was sure to find the classifica- tions and grammatic categories of Latin in any Indian language whatsoever. Aleman’s Kiché cases of the noun, dative, ablative, etc., are simply postpositions connected with a noun ; the verb coh is regarded as identical with the verb substantive, and a “ sub- junctive” is found to occur through all the tense-forms of this Guatemaltec language.—A.

In examining carefully this list and the accompanying drawings he was struck both with the generic sim- ilarities of hyperborean art and with the specific differences due to isolation. Pottery occurs in the list; labret lancets of slate for cutting the holes in the cheek for labrets ; amber-beads made by the natives, and cups of fossilivory. Of the implements, whose general form is widely diffused, Mr. Murdoch has collected a great variety of each class, showing that among these far-off people differentiation of structure for functional ends has been carried to a high degree of perfection. The Natural History chapters, also written by Mr. Murdoch must not be overlooked by the ethnologist, inasmuch as the life history of the people is inti- mately connected with the restricted fauna of this region. Mr. Murdoch will publish in the near future a minute descrip- tion of the Point Barrow Eskimo, including their arts and their customs, so far as he was able to gather facts concerning them.

The Shetimasha Indians, about a hundred in all, living on a small bayou south of New Orleans, use the single barreled blow-tube precisely like that of the Choctaws, but they also have combinations of tubes, as We would say, viz., five barreled, eight barreled, &c., blow-tubes. They are made as follows: A number of tubes, in our collection rang- ing from five to eleven, of the same length and calibre are fasten- ed securely together like a long pan-pipe by means of splints of split cane. The arrows are of split cane and vary at the point from the slender needle form to a broad arrow form. The butt end has a wad of cotton yarn 3 inches long fastened on like the bristles of a cylindrical brush. When the hunter wishes to use this weapon he loads his five or ten barrels and, stealing upon @ flock of birds, lets drive the whole set one after another in quick succession.

Conclusions. MICROSCOPY. Osmic Acip AND MERKEL’s FLUID As A MEANS OF DEVELOP- relations and internal structure, We next endeavor to ascertain which of the fluids appearing to satisfy the first point will leave the preparation in the most favorable condition for sectioning; and, finally, we have to consider the differentiating capacity of the fluids, and the conditions under which the highest differential effects can be obtained. This highly important quality, which belongs, in varying degree, te all hardening and staining reagents, serves two general purposes, one of which is purely histological, the other strictly embryological. In the one case, the aim is to sharpen the definition of individual elements, and to strengthen histological distinctions; in the other, the object is to demon- strate those subtle and imperceptible differences in the constitu- tion of embryonic cells, which furnish the earliest premonitions of their histological destiny. The histologist deals with the first class of distinctions—the embryologist must deal with both. The embryologist cannot stop with the study of structure and topo- graphical relations, as they exist in any particular stage; he is compelled to follow the entire developmental history of the cells, from their most indifferent up to their most highly specialized condition. Beginning with material more or less homogeneous in aspect, he finds it necessary to forestall development, and seeks to bring out distinctions that have not yet ripened into morpho- 1 Edited by Dr. C. O. WHITMAN, Mus. Comp. i E ona babes ie Aeolian Society of Nathalie: Depart ae 1886. ] Microscopy. 201 logical definition. In short, his task is no less than that of dis- covering, by chemical means, promorphological conditions, which shall reveal the destination of cells before nature has given them any definite histological stamp. The means that suffice to demon- strate fully formed tissue elements are not always identical: with those required in tracing their histogenetic development. As yet we know very little about the capacity of different preservative fluids in the very important work of developing nascent histological distinctions. It is often at the expense of much time and patience that reagents are found which combine the first two qualifications we have mentioned, and the experimenter who has been so far successful too frequently flatters himself that he has reached the highest rung in the ladder of technical bliss, if his preparations admit of being “sliced like cheese or cartilage.” But one re- quires no very large amount of knowledge of the aims, and expe- rience in the ways and means, of embryological research, in order to understand that the investigator’s art does not culminate in sections of cheese-like homogeneity. To be able, through serial Sections, to lay bare each individual cell of a complicated organ- ism is certainly a great triumph in microtomy; but such a feat may be, as it not infrequently has been, accomplished without leading to any important results, and simply because the methods of preparation have not been selected with a view to secure the needed differential effects. : . Having defined a special aim,in the use of embryological methods, it remains only to consider the practical side of the sub- ject. The differential effects of most preservative fluids, when used singly, are extremely weak, and often quite inappreciable. To be of service, they must be strengthened or reinforced by some happy combination of reagents, discoverable only by experiment. Dif- ferential results are generally sought for through metallic impreg- nations and through various methods of staining, as double Staining, multiple staining, overstaining followed by partial decol- Oration, etc. But I am not aware that such means alone are suf- ficient for the special purpose under consideration. In order to ‘emonstrate differences, not of form, but of molecular constitu- tion, the foundation for the desired effects must be laid in the pro- cess of hardening. Staining reagents may then serve to complete the work. : As an example of what may be accomplished in this way, I will give briefly my own experience with osmic acid and the so-called Merkel s fluid, which is a mixture in equal parts of chromic acid (% P. c) and of platinum chloride (1% p.c.). I have tested these reagents with three different classes of eggs, and have obtained im- portant results, some of which have already been published. In the case of pelagic fish-eggs, with which my first experiments were made, the method of procedure is as follows: The eggs, with a lit- sea-water, are placed in a watch-glass; then, by the aid of a pi- : 202 Generat Notes. [ February, ette, a quantity of osmic acid ( 14 p. c.) equal (as nearly as one can judge) to that of the sea-water isadded. At the end of from five to ten minutes, the eggs are washed quickly in clean water, and trans- ferred to a chrome-platinum solution, differing from Merkel’s mix- ture only in having a higher per cent of chromic’ acid, where they may remain from one to three days. After this treatment, the blastoderm may be easily freed from the yolk, and, after a thor- ough washing in clear water for a number of hours, the prepara- tion may be passed through the usual grades of alcohol, stained and sectioned, or mounted in toto.. The osmic acid fixes the natural form and structural features of the egg perfectly, and the mixture of chromic acid and platinum chloride completes the work of hardening, and at the same time removes much of the brown or black color imparted by the first reagent. I have tried various other reagents after the osmic acid, but with far less satisfactory results. Picro-sulphuric acid, instead of arresting the blackening process of the osmic acid, increases it. Simple chromic acid arrests the blackening, but does not remove it (as does Merkel’s fluid), and causes considerable contraction. Mil- ler’s fluid, recommended by Henneguy, is equally unsatisfactory. By this method a very marked differentiation is generally ob- tained as early as the sixteen-cell stage, the four central cells showing a very light brown shade, while the twelve peripheral cells have a much deeper shade. In later stages of cleavage, the distinction between central and marginal cells becomes still stronger, so that it becomes possible to trace the entire history of the origin of the so-called parablast, over which there have been so many controversies. The very difficult question as to the precise origin of the permanent entoderm is not settled by this method. The same reagents may be successfully applied to the eggs of Clepsine ; but here the mode of procedure is somewhat different, as regards Merkel’s fluid. This mixture, employed at its normal strength, is allowed to work from one to two hours only. The differential effects are here very marked, extending not only to the different germ-layers, but even to cell-groups destined to form the central nervous system, the nephridial organs, larval glands, etc. None of the methods hitherto employed with these eggs has given results at all comparable with those I have mentioned. In the case of the frog’s eggs, I allow the osmic acid from twenty to twenty-five minutes, then transfer directly to the chrome-platinum solution employed with fish-eggs (twenty-four hours). The eggs are next placed in water and freed from their gelatinous envelopes by the aid of sharp needles and a dissecting microscope. After washing in flowing water for at least two hours, the eggs may be treated with alcohol and stained accord- .,} A one per cent solution is used in place of the normal x p. c. solution. 1886. | Microscopy. 203 ing to desire. My experiments with these eggs have not yet been carried very far, and I can only say that the material, so far as examined, has turned out well. If the sectioning is not delayed too long, no disagreeable effects of crumbling will be experienced. —C. O. Whitman. Tue Funcrion oF THE Compounp Eve.—It is held by Exner, Carriére, and others that the compound eye does not distinguish the forms, but only the movements of objects. The eye would thus be merely an organ of orientation, capable of recognizing differences in the intensity of light. Plateau! has undertaken a series of interesting experiments designed to test the validity ot this view. The method of experimentation was as follows: A room five meters square is furnished with two windows, which face the west. The windows are provided with shutters, by means of which the room can be made dark. In each shutter a hole is cut large enough to receive a pane of ground glass. The vertical distance from the floor to the center of each glass is 1.75" and the horizontal distance between the centers of the two panes is 2.30" The amount of light admitted is regulated by large opening, but the amount of light that passes the former is considerably less than that which passes the latter. In successive experiments with different diurnal insects (Diptera, Hymen- -optera, Lepidoptera, Coleoptera, &c.), the size of the hole in the le diaphragm is varied, so that the amount of light is sometimes greater, sometimes less than that of the right diaphragm. If, under these conditions, an insect let loose at the side of the room opposite the windows, invariably flies to the large opening, then „we might conclude, according to Plateau, that it dis- tinguishes the forms of objects; but if it often makes the mis- sga of flying against the surface perforated with holes too small ee Bes it passage, we may conclude that it does not distinguish ‘lass ut is guided by the intensity of the light. The experiments Show that the flight is directed, in the majority of cases, towards more intense light, and hence Plateau concludes that the Bull. de P Acad. roy. de Belg., 3™¢ sér. t. x, No. 8, 1885. : 204 General Notes. [ February, view before stated in regard to the function of the com- ant purpose. This view rests on the fact that if the ocelli are covered with opaque black varnish, the insect guides its course in the same manner as before. While these experiments may be said to favor the conclusion arrived at by Plateau, they do not, in my opinion, furnish decisive evidence. It would be quite within the range of possibilities, that the insect distinguished perfectly well the forms of both the large and small holes, without taking in the relation of its own size to that of the hole through which it sought to escape. The power to distinguish forms is not tantamount to a knowledge of relations that could only be learned by experience and reflection. A METHOD oF BLEACHING WiNcs oF LEPIDOPTERA TO FACILI- TATE THE STUDY OF THEIR VENATION.—In the common method of destroying the scales on the wings of Lepidoptera, for the pur- pose of studying their venation, by means of caustic alkaline solu- tions, there is danger of not arresting the action at the proper moment, and consequently of destroying not only the portions which it is desirable to remove, but also the scale-supporting membrane, and even the delicate veins themselves. An applica- tion of a modification of the chlorine bleaching process, commonly used in cotton bleacheries, obviates the necessity of removing the scales, and Jeaves the wing perfect. alcohol in order to dissolve out the oily matter in them. If this is not done the surface of the wings acts as a repellent, and will not be moistened by an aqueous solution. When the wings have become thoroughly soaked by the alcohol they are ready to be removed to a solution of common bleaching powder. This bleach- ing powder is sold by druggists as “chloride of lime,” but it is ` really a mixture of calcic hypochlorite, calcic chloride, and calcic hydrate. Ten parts of water dissolve the first two compounds, leaving nearly all the third suspended in the solution. The solu- tion should be made with cold water, filtered, and kept ina tightly corked bottle until required for use. When the wings are trans- to this solution the bleaching commences, and in an hour or two the wings are devoid of markings, although the veins re- tain a light brown color. This is due to the fact that chlorine cannot quite decolorize animal matter, or any substance contain- ing nitrogen, as it does vegetable tissue. After the color has sufficiently disappeared from the wings they should be transferred to a wash composed of one part of 1G. Dimmock, Proceedings of the American Association for the Advancement of Science, Detroit meeting, August, 1875. 1886.] Scientific News. 205 strong hydrochloric acid to ten parts of water. And here it may be added that in case the bleaching does not readily commence upon immersion in the bleaching solution, the action may be has- tened by a previous dipping in the dilute hydrochloric acid. In the bleaching solution a crust of calcic carbonate, formed by the union of the calcic hydrate of the solution and the carbonic diox- ide of the air, is deposited on the wings, and this calcic carbonate the final wash in dilute acid will remove. As soon as the calcic carbonate has disappeared, and all bubbling, consequent upon its decomposition by the hydrochloric acid, has ceased, the wings should be well soaked in pure water. They may then be secured on cards with a mucilage of gum tragacanth ; or upon glass by the proper transfers, through alcohol and chloroform, to Canada balsam. ; A solution of sodic hypochlorite, known as Zau de Labarraque or a solution of potassic hypochlorite, known as Zau de Javelle, when used in place of the solution of bleaching powder does not leave a deposit of calcic carbonate on the wings and thus dispense with the wash of dilute acid. A solution of zinc hypochlorite acts more delicately than a solution of sodic hypochlorite, and may be used in płace of the latter, as may also solutions of alu- minic hypochlorite, or magnesic hypochlorite. my k e sVe SCIENTIFIC NEWS. — The recent meeting of the Society of Naturalists, held at Boston, December 29 and 30, will long be remembered with pleasure by thosé who had the good fortune to be present. The excellent plan of the founders of the society of limiting the range of the papers to the discussion of methods of teaching and research, leaves but small foothold for bores, and, indeed, the series of papers furnished an exhilarating succession of suggestive and easily grasped ideas. Most of the sessions were held in the physiological lecture-room of the new Harvard Medical School building and just adjoining the laboratory of Dr. Bowditch, which is probably unparalleled for its wealth of ingenious and Mective apparatus, designed and made on the spot. The courte- sies of the Harvard members of the society very agreeably occu- pied the hours not strictly devoted to business. -— Professor T. J. Burrill deals, in the Botanical Gazette, p. 334, ath two mechanical effects of cold upon trees—the radial split- ting of wood and bark, and the separation of bark or wood layers i a concentric way. . oe first is explained by water freezing in plates parallel to the. ce of an organ, and then, additions being made to the base, 206 Scientific News. [February, crystals perpendicular to the surface will be formed. Thus the wood contracting, and the ice expanding tangentially and longi- tudinally (chiefly the former), radial bursting is the result. The south side of a tree is the weakest, as more water exists there, and ice is first formed. Direct observation shows that the speci- fic gravity of sap is greater on the north side of a tree. Concentric splitting is explained by minute ice-crystals form- ing with their axes perpendicular to the wood-cylinder, thus causing radial tension. Want of ripeness of tissue, in the sense of the relation of water to other constituents, is the chief predis- posing cause. — Henry W. Beyerinck has, in the Botanische Zeitung, exam- ined the structure of the remarkable galls produced on the inter- nodes of the stem of Poa nemoralis by the attacks of Cecidomyia pow, While, under normal conditions, grasses are able to pro- duce roots only from the nodes, these galls are clothed with a thick matting of roots produced from the pericambial layer of the internodes. When first found these roots differ in no respect from ordinary underground roots, being provided with a root- cap, and a central vascular cylinder with a few pitted vessels, but with no root-hairs. In the course of development they assume more and more the character of aerial roots, and lose their root-cap. * — Count G. de Saporta enters into an elaborate reply, in the Bulletin of the Geological Society of France (x11, p. 179), to the theory of Nathorst that the supposed organic remains of a very early geological period are in reality the petrified impressions of the footprints of animals. He maintains that a minute examina- tion of their structure entirely contradicts this view, and that even those about which Nathorst expresses the greatest doubt may be petrifactions of algz in half-relief. — Dr. F.

One of the most in- teresting features of the meeting was the account by Mr. Brewster of his observations carried on at lighthouses during the season of migration. By means of these observations the speaker had penetrated deeper into some of the secrets in the life of the small bight-migrating birds than any one else has yet done.

MIGRATIONS OF SIOUAN TRIBES." BY REV. J. OWEN DORSEY. “QIOUAN” is the term adopted by the Bureau of Ethnology instead of “ Dakotan,” as the name of the linguistic family of which the Sioux or Dakotas have been regarded as the lead- ing nation. The tribes whose migrations are described in this paper are the Ponkas, Omahas, Osages, Kansas, Kwapas, owas, Otos, Missou- tis, Winnebagos and Mandans. The other tribes of this family are the Sioux, Assiniboins, Hidatsas, Crows and Tutelos. Some authors speak of a series of migrations of these tribes from the west toward the east, but the writer has not been able to learn on what authority such statements have been made, nor has he ever found any tradition of such eastward migrations among the tribes that he has visited. Whatever may be the value of Catlin’s map of the Mandan Migrations, there can be no doubt that the Mandans belong to the Siouan family. Their language shows unmistakable resem- blances to the Winnebago, as well as to the Dakota, Osage, Kan- sas, etc. The Mandan tradition, as given to Catlin, placed the ancestors of that people east of the Mississippi river at an early day (Catlin’s N. A. Indians, 1, 259)2 The Jesuit Relation of 1640 speaks of the Dakotas and Assini- boins, placing them in the neighborhood of the Winnebagos. This last nation was probably in the region of Green bay in 1614, _ "Read before the Anthropological Society, Washington, D. C., in 1884. 2 See map 2, é 15 212 Migrations of Siouan Tribes.

About three years ago the Iowa chiefs who visited Washing- ton at that time told the writer that their people, the Otos, Mis- souris, Omahas and Ponkas once formed part of the Winnebago nation. In confirmation of this note are the following statements - (2) About the year 1848 Rev. Wm. Hamilton, missionary to the 1886. | Migrations of Siouan Tribes. 213 owas, learned that when they sung their mystic songs they used the Winnebago language. (4) A careful study of the languages of the Iowas, Otos and Winnebagos shows that they are very closely related ; indeed, time may prove the necessity of including them in one group instead of two. (c) We have the tradition given by the Prince of Nieu Wied on p. 645 of his first volume (German edition). (æ) Gallatin (Trans. Amer. Antiq. Soc., 1836, p. 127) says that the Iowas, Otos, Missouris, Omahas and Ponkas have a tradition that, at a distant epoch, they, together with the Winnebagos, came from the north; that the Winnebagos stopped on the banks of Lake Michigan while the rest, continuing their course southerly, crossed the Mississippi river and occupied the places in which they were found by the Europeans. (e) There is a Statement made in Maj. Long’s account of his expedition to the Rocky mountains, 1819 (ed. by James), of which the substance is now given: “The parent nation originally resided somewhere North of the great lakes. On moving southward a large body seceded, staying on the shore of a lake; these became the Ho- chan-ga-ra or Winnebagos. Another band separated from the main body on reaching the Mississippi—these became the Iowas (Pa-kho-che). At the mouth of the Missouri another band Stopped and made a village, hence their name, “ Ne-o-ta-che ” (Ni-u-t’a-chi), now called Missouris. The Otos (Wa-to-ta, lovers of sexual pleasure) left the nation on the Mississippi (according to another account they seceded from the Missouris at the mouth of the Missouri river) and went across the country till they struck the Missouri near the mouth of the Great Nemaha. Here they remained a long time. Thence they went up to the Platte, and after hunting for some time near its mouth they moved further up the Missouri and built a village on the right bank of that river, about fourteen miles below Council Bluffs, Ia. While they were there a band of lowas established themselves on the bank of the river, _ nearly opposite to them and within thirty miles of the site of the Omaha village, in 1819. The Otos subsequently removed to the © Platte, about twenty miles above the village occupied by them in 1819, but finding the latter situation a better one, they established memselves there (about A. D. 1769).” ini =, after remaining in a village on the Lower Mis-.

[ March, This must refer to a late period in the history of the Iowas, extending back, perhaps, not further than 1740 or 1750. This will appear the more plainly after comparing the above statement respecting the Otos with the map of the migrations of the Iowas given as Plate xxx in Vol. 111 of Schoolcraft’s Archives of Abo- riginal Knowledge. A copy of the map accompanies this article, The supposition of the writer is also in accordance with what fol- lows about the migrations of the Iowas in company with the Omahas and Ponkas. “ The Missouris in course of time abandoned their village at the mouth of the Missouri, and gradually ascending the river at length built a town on the left bank, near the mouth of Grand river. They were found there by the French, who built a fort on an island in the Missouri, very near them, about the beginning of the last century. * * * The Missouris continued to dwell in the same locality until, about twenty years since (A. D. 1798, 1799 or 1800), they were conquered and dispersed by a combina- tion of the Saks, Foxes and some other Indians. Five or six lodges joined the Osages, two or three took refuge with the Kan- sas, and the chief part of the remainder amalgamated with the tos.” In 1673 the Otos were placed by Marquette! between 40° and 41° N. lat., west of the Missouri and Mississippi rivers, east of the Maha (Omahas) and south-east of the Pana (Ponkas?). The Iowas, according to the same authority, were between 40° and 41° N. lat., north-west of the Maha and west of the Pana. . In 1680 the Ainoves (Iowas) were east of the Mississippi and near the Kickapoos, according to Membré (see Shea’s Discov. and Expl. Miss. Valley, p. 150). The Otos were “one hundred and thirty leagues from the Illinois, almost opposite the mouth of the Miskoncing.” In 1687 the Otos were on the Osage river. In 1700 Iberville said that the Otos and Iowas were with the Omahas between the Missouri and Mississippi rivers, about 4 hundred leagues from the Illinois. In 1721 the Iowas were east _ of the Missouri river, above the Otos and below the Pawnees; _ being allies and neighbors of the Dakotas. The Otos were below the Iowas and above the Kansas, on the west side of the Missouri (Charlevoix, Histor. Journal, p. 294). The Ponkas told Rev. A. L. Riggs that their ancestors used tO ‘dwell east of the Mississippi. They subsequently inhabited the 1 See his autograph map in Shea’s Dj a . 8vo, a E. age p in Shea’s Discov. and Explor. of the Miss. Valley a 1886.] Migrations of Siouan Tribes. 215 country on the north side of the Missouri river, near its mouth. The Kansas and the Osages were the first to depart; then the Omahas and Ponkas followed the course of the Missouri towards its head. Mr. Riggs also says that the Ponkas went to the region of the Black hills, and were there before the Crows; but the Ponkas told the writer that the Crows inhabited that country and were owners of the Black hills when their ancestors arrived there, at which time there were no Dakotas in that region. This last statement is confirmed by the Dakota winter-counts in Dr. Cor- busier’s collection. The writer was also told that the Ponkas used to dwell north-east of the old Ponka reservation (which is in Todd county, Neb.), in a land where they wore snow-shoes. Since 1879 the writer has gained more definite information from other Ponkas, as well as from Omahas, Osages and Kansas, and it is now given. Ages ago the ancestors of the Omahas, Ponkas, Osages, Kan- sas, Kwapas, Winnebagos, Pawnee Loups (Skidi) and Rees, dwelt east of the Mississippi. They were not all in one region, but they were allies, and their general course was westward. They drove other tribes before them. Five of these peoples, the Omahas, Ponkas, Osages, Kansas and Kwapas, were then to- gether as one nation. They were called Arkansa or Alkansa by the Illinois tribes, and they dwelt near the Ohio river. At the mouth of the Ohio a separation occurred. Some went down the Mississippi, hence arose their name, “ U-ga’-qpa (Oo-ga-khpa)” or Kwapa (Quapaw), meaning “the down-stream people.” This Was prior to 1540, when De Soto met the Kwapas, who were then a distinct tribe. The rest of the Arkansas ascended the river, taking the name of U-ma™-ha® (Omaha), “those going against the wind or current.” _ These names—Kwapa and Omaha—are of more recent origin than Kansas, Osage and Ponka. We find proofs of the antiquity of these three names in the names of gentes in these tribes. Thus among the Ponkas there is a Ponka gens (the Ma-ka"), and an Osage gens (the Wa-ja-je). The Omahas have a Kansas gens (the ‘Ma™ze). The Kansas have a Ponka gens (Cedar people), am Osage gens (Deer people), and a Kansas gens (ya"-ze, asso- ‘ated, as among the Omahas, with the winds). The Osages have a Kansas gens (Ka"-se) and seven Osage (Wa-9a-9e) gentes, one 216 Migrations of Siouan Tribes. [ March, of which is the Ponka (Pa"-uka). The last is associated with the red cedar. If the true meanings of the three names have been preserved, they can be gained only in one way—by questioning members of the secret societies in the tribes. The writer has been unable to find an Omaha gens, and the only Kwapa village (not a gens) is among the Kwapas. Joutel names four Kwapa villages—Otsote, Thoriman, Ton- ginga and Cappa. The first village is called by other French writers, Otsotchave, or Otsotchoue, the third, Topinga (evidently a printer’s error), and the fourth, Kapaha. According to Shea _ these divisions of the Arkansas are extinct, but the writer has been able to find members of them still existing. When he was at the Osage agency, Indian Terr., in 1883, he met three Kwapas. From two of them he gained the following: The first village is se gt -qpa-qti, real Kwapas (Cappa or Kapaha). The second is U-zu’-ti-u’-hi (Otsote), which may mean village along an “su or lowland level containing trees here and there. The third is Ti- u-a’-d™j-ma™ (Thoriman). The name of the fourth village could not be learned from the Kwapas; but Margry tells us that it meant “small village” in the Kwapa dialect. The writer finds that this would be expressed by Ta™-ma” ji’-ga, with which com- pare Tonginga and Topinga. In July, 1687, according to J outel, two of these villages were on the Arkansas river, and the others were on the Mississippi. A visit to the Kwapas might furnish the writer with their traditions, etc. Though they must have separated from the Ponkas more than three hundred years agọ, the dialects are still so similar that the Kwapas met by the writer could understand him very easily when he spoke to them in Ponka. The Omahas and their associates followed the course of the Mississippi till they reached the mouth of the Missouri, remain- ing for some time near the site of fhe present city of St. Louis- Then they ascended the Missouri to a place called Tce-diii’-g4 a’-ja-be and Ma"’da-qpa’ -yé by the Kansas, and Ma’’-ja-qpa -dhé by the Osages.

[ March, Here, according to the Kansas and Osages, the ancestors of the four tribes dwelt together. In the course of time they ascended the Missouri and established themselves at the mouth of the Osage river. The Iowas were near them; but the Omahas say that at that period they did not know the Otos and Missouris. At the mouth of the Osage river the final separation occurred. The Omahas and Ponkas crossed the Missouri, resuming their wanderings. The Osages ascended the stream pontig their name, and at a tributary, called by them “ Tse’-4ŭ"-ya'-qa,” they divided into the qa-he’-3si (those who camped at the top of the mountain), incorrectly styled Great Osages, and the U-1sén’-ta (those who camped at the base of the mountain), popularly called Little Osages. The Kansas ascended the Missouri on the south side till they reached the Kansas river. A brief halt was made, and the journey was resumed. They ascended the Missouri on the east side till they reached the present northern boundary of the State of Kansas. There they were attacked by the Cheyennes, and were compelled to retrace their steps. They settled again at the mouth of the Kansas, till the “ Big Knives” came with gifts and induced them to go further west. Their subsequent history, as given to the writer by two chiefs, contains an account of about twenty villages along the Kansas river, then the settlement at Council Grove, Kas., and finally the removal to their reservation in Indian Terr. Let us return to the Omahas and Ponkas. After crossing the Missouri they were joined by the Iowas, according to Two Crows and Joseph La Flèche, of the Omahas. They said that this addi- tion to the party was made about the time of the separation from the Osages and Kansas. But the Iowa tradition, as given to Mr. Hamilton (see map of the Iowa brave) places the first village of that tribe west of the Mississippi, on the Des Moines river. The two Omahas just named said that their fathers followed the tribu- _ taries of the Missouri till they reached the great Pipestone quarry in Minnesota. Other Omahas have said that the course was UP the Des Moines river, which would naturally bring the wanderers _ near the quarry. The writer is inclined to believe that they ascended the Chariton river, and when at its source they would _ be near the Des Moines. As the Iowas were a cognate tribe, it was reasonable for them to unite with the others. At all events’ _ the traditions agree in this: the people built earth lodges (perma 1886.] Migrations of Siouan Tribes. 219 nent villages), they farmed and hunted. the buffalo and other ani- mals. When the game became scarce in their neighborhood, they abandoned their villages and went north-west. On reaching a place near the new haunts of the game, other permanent villages were built and they were occupied for years. So they lived till they reached the Pipestone quarry (which is not given in the right place on the Iowa map). When they arrived at the Big Sioux river they built a fort. At that time.the Yankton Dakotas dwelt in a forest region of Minnesota, near the Mississippi, and were called “ Ja"/-a-ja_ni/-ka-ci’-ga, people (dwelling) in the woods.” By and by the Dakotas made war on the Omahas and * their allies, defeating them and killing about a thousand warriors. This obliged the three tribes to abandon their habitat. They fled south-west till they reached the lake where the Omahas and Pon- kas obtained their sacred pole. This is now called Lake Andes, and it is at the head of Choteau creek, Dakota. There the sacred Pipes were given, according to the Omaha and Ponka traditions, - and the present gentes were constituted. From this place they ascended the Missouri river till they reached White river (Ni-u’- ga-cu’-de). There the Iowas and Omahas remained, but the Ponkas crossed the Missouri near the mouth of the White river, and went on to the Little Missouri river and the country near the Black hills. They subsequently rejoined their allies and all de- scended the Missouri on its right bank. When they reached the mouth of the Niobrara river the final separation was made. The Ponkas remained there. The Omahas settled on Bow creek, Neb., which they called “ Village stream.” The Iowas advanced to the stream on which is situated the town of Ionia, Dixon county, Neb., hence its name, “ where the Iowas farmed.” By and by the Omahas removed to a place near Covington, Neb., which is opposite Sioux City (see 24 on Map1). The remains of this village are known as Li jafi-ga jifi-ga, and the lake near by is en “ Dhix-u-cpa"-u-gdhe,” because of the willows along its In the course of time the Iowas passed the Omahas again and made a village near the place where Florence, Neb., now stands. After that they continued southward till they reached their reser- vation at the Nebraska and Kansas line. The Otos were first E, by the Omahas, according to Mr. La Flèche, in compara- tively recent times on the Platte river. uad 220 Migrations of Siouan Tribes. _ [ March, Subsequent Migrations of the Omahas.—After leaving Ji Jafiga jiiga (No. 24), where the lodges were made of wood, they dwelt at Zande buja. This is south-east of Ji jafiga -jifiga, and is the name of a stream as well as of a prominent bluff near by. This stream empties into Omaha creek near the town of Homer, Neb. After a great freshet the Omahas crossed Omaha creek and made a village at or near Omadi, which was called Large village, near Village stream (Omaha creek). See No. 25 on Map 1. This was a favorite resort, as we shall see. Thence they removed to Bell creek, on the west side of which ‘they made a village (No. 26). Thence they went south to Salt creek, below Lincoln (No. 28). Thence they returned to Large village (No. 25). When they were there, Half-a-day, the aged historian of the tribe, was born. This was about A. D. 1800. Thence they removed to A-ne na- tai dha", where the people perished ina prairie fire, a hill on the Elkhorn river (No. 30). They stayed there five years. Then they settled on Shell creek, which they called Tacnafiguji (No. 31). After which they returned to Large village (No. 25). Leav- ing this again, they made a‘village on the Elkhorn, near Wisner (No. 33), about A. D. 1822-3. Half-a-day married when he was there. About A. D. 1832-3 they returned to Large village (No. 25). Joseph La Flèche remembers having been there at that time. About A.D. 1841 they removed to Ta”-wa" jifiga dha”, the Small village (No. 35), at the mouth of Logan creek, where they dwelt for two years. In 1843 they returned to Large village (No. 25), and in 1845 they made a village on the curvilinear top of a plateau, near Bellevue (No. 37). In 1855 they removed to their present reservation, The Ponkas did not occupy their new country unmolested. They had some fights with the Cheyennes and Comanches. These foes dwelt near a great lake in a sandy region (gi-za’ -ba-he-he’) near the head of the Elkhorn river, Neb. At this time the com- _ batants used wooden darts instead of bows and arrows. The writer was at the old Ponka reservation, Todd county, Neb., from May, 1871, to Aug., 1873. During this period he often visited € remains of an ancient Ponka fort not more than a quarter of a mile from his house. A rough diagram of this fort is given. After the Iowas, and Omahas went south the Ponkas claimed all the northern part of Nebraska, along the Missouri river, as far : as what is now Dakota county, where began the Omaha ter- + 1886, ] Migrations of Siouan Tribes. 221 The Ponkas say that they had seven “old men ” since they be- came a separate tribe.

[ March, or more. If the Ponkas use the term in this sense, and are cor- rect in so doing, they may have had a tribal existence for about 490 or 500 years. This would extend back as far as A. D. 1390 or 1380. (It was told the writer in 1880.) Let us see how this agrees with the reports of early writers taken in connection with the period required for the migrations which have been described. We must remember that in those days firearms were unknown, and that therefore the destruction of game was not as rapid as it now is; that horses could not be had, rendering locomotion very slow ; that removals from permanent villages (such removals de- pending on the destruction and departure of game) need not have been at very short intervals, especially when the construction of of such villages was a work of great labor, owing to the primi- tive character of the tools employed, and has a religious signifi- cance, being accompanied with sundry mystic rites, some of which are still preserved among the Osages and Kansas. The director of the Bureau of Ethnology found a tradition among some of the civilized tribes in the Indian Territory, refer- ing to the ancestors of the Kwapas, etc., which agrees with what has been said, 2. e., that they dwelt east of the Mississippi prior to. A. D. 1700. In 1673 Marquette had heard of the Maha (Oma- has), Pana (Ponkas ?), Pahoutet (Iowas, Pagotce) and Otontantas (Otos), as inhabiting the country on the right bank of the Mis- souri river. The separation of the Iowas, Omahas and Ponkas, and therefore all previous migrations, must have occurred before 1673. Furthermore, the separation of the Kwapas from the others, and the taking of these correlative names, Kwapa and Omaha, must have occurred prior to A. D. 1 540, as De Soto met the Kwapas in that year. Even at the present day, when horses have been available, the Omahas have remained in a permanent village for ten years at a: time, and have returned repeatedly to such an old village. We have no recorded tradition of similar returns to favorite villages in prehistoric times, yet such returns may have occurred, and if. known would tend to increase the duration of the period between the meeting of the white men and the time when the Indians ~ In question were east of the Mississippi river. v 1886.] The Torture of the Fish-Hawk. 223 THE TORTURE OF THE FISH-HAWK. BY I, LANCASTER. HILE engaged in the task of explaining the mystery of the flight of soaring birds on the shores of the Gulf of Mexico, where many species abounded, unusual and astonishing perform- ances were witnessed on the part of these inhabitants of the air. The month of March revealed more of these out-of-the-way feats than other times of the year, and as the breeding season occurred in this month, especially on those remote keys and in- terminable flats constituting the peninsula of Southern Florida, it was fair to `presume that feelings growing out of the relations of the sexes prompted the remarkable behavior. Were it not absurd to transfer to external nature those moral €motions generated in the mind from the primordial impressions of pleasure and pain, one would be tempted to assert a radical diabolism in the scheme of things on witnessing the seeming fiendishness of some of these creatures having dominion of the air. Nothing but a free application of the doctrine of the trans-. mission of qualities through inheritance, coupled with variations amounting to divergence, as the line descends, can dispose of deliberately evil intention somewhere, or of a natural process, the outcome of which is bad. No inference from the hooked beak and grasping talons of the carnivorous birds gives a clue to the origin and development of a disposition on their part to inflict pain for the mere sake of the torture. Those structures find their function in the legitimate life struggle, but the infliction of needless pain, in no way connected with that conflict, seems to be imposed from another source, _ The distribution of land and water on the Gulf coast of Florida is favorable to the existence of fish. The interminable flats, bare, Or covered with a thin sheet of water at low tide, and traversed by many winding channels, give the smaller kinds refuge from the rapacity of the larger, and furnish breeding grounds without The many tidal creeks, often a succession of deep holes connected by mere rivulets, through which the tide sluggishly and flows, also give security for the deposit of eggs and ‘Srowth of young. The gulf is also a vast caldron of warm water, Prolific through its whole extent in monsters of the deep, many of which, such as sharks and porpoises, penetrate the passes 224 The Torture of the Fish-Hawk. [| March, between the keys and entering the channels of the bays play havoc with the lesser tribes. These are devoured in great quantities, and the killed and wounded which escape the maw of their fierce enemy can be seen stranded on the flats at low tide. All this teeming life goes on in a climate of surpassing loveli- ness. Frost is a rarity; ice unknown; day succeeding day of delightful blandness. Extreme heat is not experienced, and storms worthy of the name very rare. The soil of the lower peninsula is pure sand as sterile as Sahara. The vegetation is prolific in air plants, semi-tropical bushes and stunted growths, and a perpetual verdure is everywhere. But there is nothing in it all that a man can live on, and hence the population is limited to the sporadic migrations of excursionists and invalids, and a few “crackers,” always hungry, and seeking something capable of being devoured. This combination of circumstances forms a splendid environ- ment for such birds as can in any way subsist on a fish diet, and what might be expectcd is what is found. Birds with legs long enough to wade on the flats; those which have inherited the expertness of a swimming-school adept and can dive with ability, and those which can subsist on the carcases of unfortunates, have here everything pretty much to suit them. Long lines of pelicans can be seen on every hand, with that grandmotherly air of supreme contentment arising from a continuously satisfactory cuisine. Cranes of all lengths of legs and necks, stalk about, hastily gob- bling their prey. The Carrion-eating vultures are always present enjoying the incoming breeze by resting in it on motionless wings, or wheeling about on the lookout for subsistence. But the birds which particularly interest us are the fish-hawks, also dependent, like the others, on the life found in the tepid waters. These birds are arboreal in their habits, nesting in the tops of the pine trees and rarely resting on the ground. They fish for the most part in the creeks and secluded inlets, hovering over the waters and suddenly capturing their victim by diving upon it. _ But they sometimes come over the open waters of the bays, and when the keys are covered with trees, over the gulf, to find their _ food. On first acquaintance their actions seemed inexplicable. I Ss could not account for their eccentric ways. While in the hidden _ places of the creeks they utter no cry, and seem to be efficient masters of the craft, but in the open they vacillate painfully- 1886. ] The Torture of the Fish-Hawk. 225 They are large, active-winged birds, never soaring, are quite strong, and weigh about six or seven pounds. On leaving the trees lining the shore, perhaps allured by a school of mullet in the channel, they seem eager for action, and all alive with expec- tation, but just before stooping on the fish would set up a fright- ened, discordant scream, and make for the shore with a haste so ill-advised as seriously to impede progress. Before the trees were reached, confidence would be restored, and returning, the same singular performance would be repeated, perhaps for three or four times before the game was finally secured. No enemy was in sight. The breeze would flow gently. All was serene, yet terror would take possession of the bird and almost paralyze its efforts by making it frantic. I soon learned the reason for this coward- ice. Stretched at length on the deck of a boat in the early morn- . ing in the pass of Boca Grande, one of the entrances to Charlottes harbor, I saw a fine specimen of hawk cross overhead and pro- ceed seaward to find a dinner. The excursion was successful as the pass swarmed with fish coming in with the tide. A fine one soon left its element and swung aloft into the air in the talons of the bird, which at once began its return. But a new-comer ap- peared upon the scene. A black creature which seemed all wings and shaped like a flattened letter M, dropped from above and con- fronted the hawk, which at once dropped its prey and uttered a Scream so brimful of mortal terror that it should have excited the sympathy of all living things within the compass of its sound. It was not disturbed by actual contact. The two birds were not within fifty feet of each other, but the hawk exerted itself with the same wild energy to get to cover which I had before so often witnessed when no black monster was in the vicinage. The in- truder was a frigate-bird, and on looking upwards a score of them could be seen a mile or more from the earth, floating round and round, on motionless wings. The dropped fish was seized in the beak of the bird long before it reached the water, and with a Sweep of exquisite grace, on tense wings, fronting a mild breeze, the corsair was lifted half a mile into the air, where another aston- ishing performance was at once initiated. A bite was taken from the body, being torn away by a wringing motion of the head which sent the carcass whirling, while the bird masticated the morsel in shape for swallowing. Of course the fish began to obey the law of falling bodies, and the bird, folding its wings e 226 The Torture of the Fish-Hawk. [ March, tightly upon its body, dropped swiftly after it. The part bitten off being disposed of, another swoop downwards was made, the fish seized, and the upward swing repeated, and this process continued until the entire carcass was devoured. At the time of this visit these frigate-birds were oblivious of man’s presence and I was so fortunate as to secure this one by a well directed shot. It measured eleven feet in alar dimensions and weighed eight pounds. Its feet and legs were ridiculously small and weak, and viewed as weapons of offense and defense could not compare with the talons of the hawk it had robbed and terrified. Its head and beak were strong and well developed, but by no means superior to those of the other. The terror which inspired the hawk was still unaccounted for. In a contest for superiority on the ground of physical strength and effectiveness of weapons it would have been victorious. The whole case was still enveloped in mystery. Returning to this locality-after the absence of some weeks I found the black outlines of the frigate-birds against the sky as usual, and soon saw the inevitable hawk over the waters of the pass all excitement at the prospect ofa dinner. It was the begin- ning of March, and in that month the sea-breezes of the vicinity are particularly delightful. It is also the breeding season of the birds when their plumage is at its best, and they show to best ad- vantage. Success always followed any well directed effort of a bird to catch a fish in Boca Grande pass, and the hawk soon had one. A black corsair at once appeared and captured the booty as on the former occasion, while the frightened fisher fled scream- ing towards the land. But now a change of programme took place. Another long winged creature from the group above appeared in front of and facing the frightened hawk which turned seaward at once, mingling its note of terror with one of despair. Every effort to side off towards home was frustrated by the gliding terror in- terposing its bulk in the intended direction, until the victim seemed to accept the inevitable and made an attempt to cross the gulf. The tormenting enemy then seemed content, and swung aloft among its companions. The poor fisherman, rid of the dire _ presence, wheeled on its course for home, and its frenzied flap- _ pings relieved of excessive tension, made very good time, when ~ On reaching the very brink of safety the black wings again ap- _ peared and the whole distressing business was re-enacted with PLATE XI. The Frigate Bird. 1886, } The Torture of the Fish-Hawk. 227 increasing despair in the frightened crys This went on for more than half an hour. Every effort at retreat was intercepted. During all the time the hawk kept up an incessant flapping of its wings, ‘and its physical endurance was giving way under the protracted strain. This was apparent from the changing tone of its scream, which varied through all the gamut of despair, from unreasoning terror, to supplicating misery. It was the Roman gladiator’s “ Cæsar, the dying salute thee,” with the ambition left out. The frigate-bird at length seemed impatient. It more promptly answered the movements of the hawk, and urged compliance with greater vigor, and finally introduced a new feature into the proceed- ings. Swooping upwards for one hundred feet it turned head fore- most, and plunged beneath the hawk, turning completely over as it did so, and passing to the front vaulted upwards, and down again in the same path, thus describing an elliptical orbit around its victim. It swung near the hawk round the lower curve, causing upward flight, until at length in an exhausted condition it was in- troduced into the company of its tormenters which had been de- scending from high levels and were now about four hundred yards above the water. Its strength was now well nigh exhausted. Its cry was scarcely audible, and it barely had the power of di- recting its movements. In whichever way it went, excepting one, a black terror confronted it. It could rise unimpeded, but found resistance to every other course. It struggled upwards for some four hundred yards further, until the distance was so great as to make it difficult to keep the movements in the field of the glass, when it gave up the task, and rapidly floundered over and over through the air, its muscular power exhausted, and its mass sur- rendered to the gravitating force. Down it came, the whole half- Score of enemies circling about it, until it struck the water near the beach in the shallows of the offing. The tide was running out and the water on the flat not over a foot in depth. : Supposing the play to be out I was proceeding to examine the victim when it was evident that more was tocome. The hawk was not dead and would at intervals raise its head from beneath the water to breathe. It had not strength to submerge its body, and with the vital air came a vision of the hovering terror. Down went its head with a gurgling murmur, and those black demons a ioe would alight upon it with their miserable puny feet and push Eoo entirely beneath the surface. VOL. XX,—No. 111, 6 ~ 228 The Torture of the Fish-Hawk. [March, The vitality of the fish-hawk is something wonderful, for this pastime went on for an hour, until at length it was completely dead. The body floated to shallow parts in the ebbing tide and rested stationary on the bottom, when each bird in turn alighted upon it, folded its wings, and rested in perfect quiet for five min- utes, when it would rise in the air and a comrade take its turn. The appearance of these creatures, while thus employed, was that of quietly expecting something which did not happen. I had approached to within thirty feet of the dead hawk, but not the least attention was given to my presence. The birds always alighted with their heads towards the head of the carcass, and stood out their time, without making a movement, in a slightly crouching attitude, as if to be prepared for what would take place. This curious performance lasted for an hour, when, moved by a single impulse, they stretched their long pinions and went aloft, where they could be seen in their interminable circling flight, round and round,yand the tragedy was ended. The sun was low in the west; the tide had ceased to flow; the breeze had died away, and everything was tranquil. All nature seemed to overflow with love and peace, and yet an awful scene had filled those quiet hours. I felt myself in the grasp of some- thing infernal. It was as if the guest of Solomon had been con- fronted in the garden, in every avenue of escape, by awful death, — until he had surrendered life after exhausting all the forces of his _ nature to escape his doom. An examination of the carcass re- vealed no wounds. It wasa case of suicide entirely. But what a dreadful motive to commit the deed, ~ Through all this tragedy the wings of the frigate-birds were motionless, excepting when they were engaged near the water. To rise or fall was indifferent to them. When confronting the wks, the contrasted wing-motions of the two birds was con- spicuous—one was beating the air rapidly, the other not at all. Though afterwards explained, this ability to counteract air resist- ance and weight without muscular exertion was then as great a riddle as any other part of the work. _I remained in that locality for a month, but witnessed no repe- tition of this day’s tragedy. The frigate-birds occupied the air and the hawks fished in the pass undisturbed, or if their prey was stolen, they were allowed to escape; but on returning a year afterwards, I witnessed an analogous scene, after waiting for w ecks 1886.] The Torture of the Fish-Hawk. 229 for the event to occur. A hawk, quite differently marked and much larger than those usually seen, crossed from the opposite key and struck a fish from the passing school, which was promptly seized by the waiting frigate-bird. The hawk fled in terror, as usual, and was confronted by another of the band and, on exam- ing the sky, still another, three in all, was seen. After the con- fronted hawk had turned, it seemed to lose its terror, its cry denoting submission, a sort of querulous surrender to the inevi- table. To my surprise, it resumed its fishing, while the rover retired. It soon secured another from the teeming waters, for all it had to do was to pick it up. This was captured and the scream- ing retreat once more arrested. A simple hint was quite enough. The slave returned to its task with many an unnoticed murmur, until each bandit had secured a feast. The hawk then escaped hungry, and disappeared from sight. After witnessing this way of getting a living, a black garment seemed lifted from nature. The method was so like that practiced by man, as shown in history, that it quite contented me. These frigate-birds are the banditti of the air. During a residence of five years on that coast, I never saw one get an honest living. They seem to be the especial favorites of nature, as the cosmical force of gravity is placed at their disposal, which is a little like giving them the lamp of Aladdin. Small use would it be for a Creature required to provide its own motive power to sustain Itself in air, and also that required to fight a battle for life, to oppose such odds. The relation to success such combatants would stand in would be almost infinity to one, A familiar sight along that coast, at all seasons of the year, is that of gulls riding on the backs and heads of pelicans and feed- ing on the fish from their gullets. There is a good understanding between these creatures, and I never saw them quarrel. Some- times when fish were scarce and the small intruders wanted all, a contest as to which could swallow.the most in the shortest time took place, to the usual discomfiture of the little ones, who never seemed to understand how nor why the food disappeared. This Scheme of subsistence-supply gave the missing link needed to acquit nature of deliberately plotting the torture of her crea- tures. Away back in the great secondary age, when reptiles — navigated the air on wings, the characteristics of a frigate-bird — may have been initiated. In the life-struggle, habits of the gull 230 A Study of Garden Lettuce. [ March, were acquired which led the creature, ż4en neither frigate-bird nor gull, to get its food by association with some messmate more able to procure it. Then these two forms diverged from the common ancestor, acquiring new traits from new environments. As the frigate-birds gained dominion of the air, they also gained domin- ion of species of fish-hawks, which became enslaved by them. But the hawks also diverged into other species, one or more of which retained the terror, but not the discipline, and, when com- manded, would not comply, through sheer ignorance of the nature of the demand. When the birds met with a specimen of this branched stock, they urged obedience with such vigor as to result in the death of their unfortunate victim. Then the old ancestral habit, which may be had outlived a thousand generations, comes into play, and they stand on the dead body, in pure friendship, waiting to be fed! What do they know of the mystery of death? The only weak place is where the branching hawk forgot the duty of fishing for its master, but not the terror of its presence. But then fear is what prompts it to escape from an enemy and thereby save its life, so that this emotion would properly survive the other. :0: A STUDY OF GARDEN LETTUCE. BY E. L. STURTEVANT, M.D. ty the New York Agricultural Experiment station, in 1885, eighty-three distinct varieties of lettuce were grown undef nearly two hundred names. These lettuces present to the on- looker three distinct form-species, the lanceolate-leaved, the Cos and the cabbage. It is a pertinent inquiry as to whether these form-species are of distinct origin or have been produced by cul- tivation within recent times, and we hence offer a succinct ac- count of our historical investigations. * The lanceolate-leaved form is represented with us by one vari- ety only, the deer’s tongue, introduced as a seedsman’s novelty in 1883. The type of this form is perhaps referred to by Pliny, lib. XIX, c. 38, “ præterea longi et angusti intubi similis,” as this plant _of ours has a chiccory-like appearance in some stages of its growth. It is certainly mentioned by Bauhin? in 1621, and cred- ited in his synonomy to Castor, 15855 ; and is figured by Bauhin? 1 Pinax, ed. of 1621. * Prodromos, ed. of 1671, 18386. ] A Study of Garden Lettuce. 2 31 in 1671. Vilmorin,! 1883, refers to this type of lettuce under the name Romaine asperge, Lactuca angustana Hort., and a variety L. cracoviensis Hort. L. angustana Allionii, 1785, seems to be of this form-species, and is recorded as found wild in Switzerland, and Martyn’s Millers Dictionary deems the Chicoreum constanti- nopolitanum of Parkinson, 1640, to have some affinity to it. The Cos lettuces are distinguished by the upright growth of the root leaves and the elongated and spatulate form of the leaf; they are also subject to a flattening of the stalk through fascia- tion. They were perhaps known to the ancient Romans, as wit- ness Pliny’s’ statement: “ Diligentiores plura genera faciunt : pur- purea crispas, Cappedocas,G . Longioris has folii, caulisque angusti, intubi similis.” Palladius’ men- tion of the process of blamehing can be also quoted: “ Candide fieri putantur, si fluminis arena vel litoris frequentur spargatur in medias, and collectis ipsz foliis alligentur.” The Cos lettuce is the Lactuca Romana dulcior, nigriore and Scariole hortensis folio, semine nigro of Pena and Lobel, 1 570. Bauhin in his Pinax considers this form to be the L. foliio obscurius virentibus nigra Plinio of Dodzenus,® the Z. nigra of Czsalpinus, 1583, and the Z. romana of Castor Durantes, 1585. In the sixteenth cent- ury the Cos form seems to have been less grown in Northern Europe than in the south, for Pena and Lobel® say it is rarely cultivated in France and Germany, more frequently in Italy, espe- cially at Rome. It reached France in 1 537. The class of cabbage lettuces are distinguished by the rounded and spatulate leaf which grows less upright than the Cos. Al- though the commentators of the sixteenth and seventeenth cent- uries deem this class to have been known to the ancient Greeks and Romans, and identify it with the Laconicon of Pliny and the Tartesian or Bætica of Columella, yet I am unable to find any certain evidence. The only word I find in Pliny which could Suggest this class is “crispa,” which may be translated “ wrin- kled,” and as a class the cabbage lettuces are more wrinkled or - ~ 'Les Plantes Potageres. 7 Nat.

He? speaks of two kinds which may belong to this class, one the Cappadocean “Tertia, que spisso, sed puro vertice pallet,” and “quz pallido and pexo denso- que folio viret;” the other the Tartesian or Bætica, which he says is from his country : “Et mæ, quam generant Tartesi litore Gades Candida vibrato discrimine, candida thyrso est,” > and “ quz deinde candida est and crispissimi folii, ut in provincia Betica and finibus Gaditani municippii.” The words “ vibrato discrimine ” and “ crispissimi folii” would imply a curled cutting lettuce.

Anton Pinaeus,? 1561, figures one which closely resembles the stone tennis ball variety of our gardens, and Bauhin in his syn- onymy identifies with varieties described by Tragus, 1553, Tab- ernzmontanus 1588, Matthiolus 1586, Gerarde 1 507, etc; etc. Whether the types of the Cos and the cabbage form-species occur in nature, I have not the material for study to determine. De Candolle? says “ botanists are agreed in considering the culti- vated lettuce as a modification of the wild species called Lactuca scariola. The latter grows in temperate and Southern Europe, in the Canary isles, Madeira, Algeria, Abyssinia and in the tem- perate regions of Eastern Asia. Boissier speaks of specimens from Arabia Petrea to Mesopotamia and the Caucasus. He men- tions a variety with crinkled‘ leaves, similar, therefore, to some of our garden lettuces, which the traveler Hausknecht brought with him from the mountains of Kurdistan. I have a specimen from Siberia, found near the River Irtysch, and it is now known with certainty that the species grows in the north of India, in Kash- mir and in Nepal.” From this reference we might infer that the Kurdistan form belonged to the cabbage type, as possessing dis- tinctly wrinkled or savoy-like leaves, while the description of the ordinary L. scariola of Europe implies the Cos type. : I have not opportunity of access to herbariums whereby I can hope to satisfy myself of the condition of the wild forms from 1 De Re Rustica, x, l. 183; XI, c. 35 tb. 18S * Hist.

Lettuces are supposed to have been grown by the Persians some five hundred years be- fore Christ, and to have been introduced into China between the years 600 and goo of our era; they were mentioned by Chaucer in England in the fourteenth century, and reached America with Columbus. ve td AQUATIC RESPIRATION IN SOFT-SHELLED TUR- TLES: A CONTRIBUTION TO THE PHYSIOLOGY OF RESPIRATION IN VERTEBRATES? BY SIMON H. AND SUSANNA PHELPS GAGE. e was formerly supposed that in all reptiles the respiration was exclusively aérial at all periods of their life, and that the lungs were the only respiratory organs. We have demonstrated, how- ever, that in soft-shelled turtles (Amyda mutica and Aspidonectes Spirifer) there is in addition a true aquatic respiration. This is żin- dicated by three facts: (a) These turtles remain most of the time in water, and voluntarily remain entirely under from two to ten consecutive hours ; (4) while under water they fill and empty the mouth and pharnyx, about sixteen times per minute, by move- ments of the hyoid apparatus, the general appearance being like the respiratory movements of a fish; (c) the mucous membrane of the pharynx is closely beset with filanientatis processes, appéar- ing like the villi of the small intestine of a mammal or the gill filaments of Necturus. These processes are especially numerous along the hyoid arches and around the glottis, and are copiously Supplied with blood? ‘A croton paper upon the respiration of Aspidonectes was presented to the A.A by the senior author in 1883, and printed on p. 316 of the Proceedings (Vol. xxxi). ? So far as we know but two original observations (besides that mentioned in the : Preceding foot-note) have been previously made upon the Trionychidze bearing nee 2 the subject of this paper : (a) In February, 1856, Dr. A. Sager called the processes in the pharynx of Aspidonectes, and co: ces < with the gill filaments of Necturus and the inner gills of tadpoles. o Professor L. 234 Aquatic Respiration in Soft-shelled Turtles. {[March, But neither the time the turtles remain under water, the filling and emptying of the mouth and pharynx, with water, nor even the structure of the parts, proves that aquatic respiration occurs. Final proof of this is only obtained by comparing the free gases found in water with those found in water from the same source alter a turtle had been submerged in it without access to air. Water so tested showed in one case that a turtle weighing one kilogram in ten hours removed from the water seventy-one milligrams of free oxygen and added to it 318 milligrams of carbon dioxide, Several other determinations were of the same conclusive char- acter. This indicates a respiration for the same body weight of about one twentieth of that occurring in man. As indicated by the figures given above, the carbon dioxide is greatly in excess of what could be accounted for by the free oxygen taken from the water. There are two sources from which the extra oxygen might be derived: (a) From the so-called intra- Agassiz, in Part 11 of the Contribution to North American Zodlogy, p. 284, sa “ Before reading this paper [Dr. Sager’s] we had noticed these organs [processes a the pharynx]; but after seeing this turtle [Aspidonectes] remaining under water for full half an hour without showing the least sign of oppression, it seems plausible to assume that these fringes may be similar to the internal gills of tadpoles, not only in their shape but also in their function. There exists, moreover, an extensive network of beautiful vessels spreading in elegant dendritic ramifications upon the whole lower surface of the Trionycidze which can hardly have another function than that of assisting in the process of breathing, as they are too numerous and too large to be considered simply as nutritive vessels of the skin. This is the more probable as these vessels are very superficial and are only covered by a very thin epidermis. They are indeed as plainly visible through the e s = protects them as the vessels of any special external breathing organ. ‘The following table shows the results of three analyses. In the first column is the total amount of free oxygen taken from the water (ten liters) in ten hours by a turtle weighing one kilogram. The second column contains the quantity of tains the actual amount of carbon dioxide added to the water by the turtle, the ex- cess of which, over the amount that could be formed from the oxygen taken from the water, is given in the fourth column : : k 0. | C0. | Actual CO, Excess COy Juy Iisssses 71mg. 97 53mg. | 231 mg. 133 3-8 mg. oe sa go 44 $ 212.7 “ 1687 “ aes soco] 39 5353 168.7 “ 15s Ss _ The determinations were made with the greatest care and accuracy by Profes- sors Rich and Holton in the chemical laboratory of Cornell University. 1886. ] Aquatic Respiration in Soft-shelled Turtles. 235 molecular oxygen stored up in the tissues, and (0) from the air in the lungs. Analysis of the air taken from -the lungs after the turtle had been wholly submerged for ten hours, showed only a slight trace of either oxygen or carbon dioxide. So far as this single experiment goes, we conclude that if the lungs were moderately filled with air upon the immersion of the turtle, the amount of oxygen that might be taken from the air in the lungs would fully account for the excess of carbon dioxide found in the water. That the aquatic respiration is due almost entirely to the pharynx and but slightly to the skin, is shown: (a) By anzsthetiza- tion, the turtle becoming anesthetized four or five times as quickly when kept entirely submerged in ztherized water as when allowed to come to the surface as frequently as it desired. (4) When the turtle’s skin was completely covered with vaseline and the turtle kept wholly submerged, the amount of oxygen removed from the water and of carbon dioxide added thereto was nearly as great as when the skin was unvaselined. In some at least of the hard-shelled turtles (Chelydra and Chrysemys) similar movements of the hyoid apparatus occur when they are submerged, and water is seen to enter the nos- tril and be expelled therefrom as in soft-shelled turtles. The pharynx expands and contracts with considerable regu- larity in all of the turtles, so far as we know, when they are in eair. These movements appear like those of the frog, but in the turtles they are unnecessary for filling the lungs. In frogs, however, they are necessary for this purpose, although as shown by Townson (1794), pharyngeal movements often occur in the frog without any air being forced into the lungs. As these movements are of undoubted use in respiration for the soft-shelled turtles in water, it seems probable that they may of use in respiration for all turtles in tHe air, that is, the mem- brane lining the pharynx probably acts as a respiratory organ whether the medium bathing it and containing free oxygen be _ air or water. These movements and their object, respiration, then seem to | connect, physiologically at least, the turtles on the one hand with the lower vertebrates—Amphibia and fishes—and on the other hand with the higher forms, viz., dog and man, for Garland has — oe ; shown that in the dog, and also in man, occur rhythmical me Fyngeal movements which draw air into the pharynx and expel it 236 Description of a new Subspectes | March, whenever there is a condition approaching asphyxiation. It seems as though these pharyngeal movements reappear in the highest forms when the want of oxygen becomes overwhelm- ingly great, as if there were an organic memory of the means by which, in the dim past, the want was supplied. 20: DESCRIPTION OF A NEW SUBSPECIES OF THE COMMON EASTERN CHIPMUNK.

The specific name striatus, after en- during the vicissitudes to which scientific nomenclature is so often subject, was reéstablished by Baird in 1857, and has since en- joyed undisputed recognition on this side of the Atlantic. It is a little singular that thus far no one seems to have sus- pected the existence of two distinct subspecies of chipmunk in Eastern North America, particularly when it is remembered that no less than five geographical races of the Western species have long been recognized. It is true that Professor Baird, nearly, thirty years ago, stated that a chipmunk from Essex county, in Northeastern New York, 14 SCIURUS STRIATUS. The Ground Squirrel. Thisis about half the Size of an English Squirrel, and almost of the same Colour, except that a Pair of black Lists, with a yel- lowish white List between them, extend almost the Length of the Body on both Sides; also a single black List runs along the Ridge of the Back. The Eyes are black and large, the Ears rounding, the Tail long, flat, and thick set with Hairs, which are much shorter than those of other Squirrels. These Squirrels abide in the Woods of Carolina, Virginia, &c. Their Food is Nuts, Acorns, and such like as other Squirrels feed on. They being brought up tame, are very familiar and active.” (Natural Hist, of Caro- lina, ete., by Mark Catesby, Vol. 11, 1743, P. 75): l 2 For more than half a century our animal was confused with the Asiatic, but it is not the purpose of the present paper to enter into a discussion of the complicated synonymy of these species, already very fully elaborated by Allen.

In a specimen from Washington [D. C.], the chestnut tints are darker than described above” (North American Mammals, 1857, 294). But his material was not sufficiently extensive to enable him to appreciate the constancy and signifi- cance of the differences noted. | Allen, in his most valuable paper on Geographical variation in color in North American squirrels, said: ‘‘ The increase in in- tensity of color from the north southward” is well illustrated in “ Tamias striatus, representatives of which from the southern parts of New York and Pennsylvania are much more highly colored than are those from Northern New England and the British Provinces” (Proc. Bost. Soc. Nat. Hist., Xv1, 1874,4). Later, however, the views above expressed seem to have undergone some modification, for the same author observes: “The very large number of specimens before me indicate that the present Species preserves great constancy of coloration. * * * Speci- mens from Southern localities are considerably brighter colored than those from more Northern sections, and average a little smaller. The difference, however, in either respect, is not very great ” (Monographs of North American Rodentia, 1877, 784- 785). The examination of more than two hundred specimens has led me to differ with Mr. Allen in his last expressed views. His remarks concerning the deepening of color southward might have been stated more strongly, and still fall within the limits of truth.’ In respect to size, if the body as a whole was meant, my measurements of upwards of one hundred specimens in the flesh do not show the Southern animal to be the smaller, and the largest individual that has fallen under my notice came from Monticello, Mississippi. If, however, we turn to the extremities, the case is different, for the length of both fore and hind feet is greater in northern than in southern specimens, as shown in the accom- Panying tables: eS eos eee 2 Mr. Allen’s views, as above enunciated, were based upon the examination of upwards of one hundred and fifty specimens; still, it is but fair to state that the Sreat majority of these specimens came from Northern localities, and were either YPical of the Northern form or intermediate between it and the Southern.

Fisher, at my request, sent me several chipmunks from Sing Sing, New York, in the valley of the Lower Hudson. On placing them alongside my own series from the Adirondack region I was at once struck with the marked differences between them, and was convinced that they were subspecifically separable. This opinion was confirmed the following year by the acquisition of an adult female from the mountains of North Carolina, kindly presented to me by Mr. William Brewster, who killed it in the town of Sylva, Jackson county, North Carolina, May 30, 1885. This individual, for two reasons, may be regarded as the type of sfriatus proper: First, because it came from the same general region from which Catesby’s probably came (and it will be remembered that Lin- nacus’s diagnosis was based on Catesby’s description and figure); and, second, because it is representative of a phase of pelage most remote from that of the Northern animal.

There is an indistinct dark line above the light line of the upper eyelid, and a broad, but not well defined, dark stripe below the light under eyelid, extending from a point anterior to the eye to a point just below the posterior base of the ear, where it becomes lost in the grizzled rusty-brown of the sides of the neck. Below this stripe, the side of the face is fulvous. The crown is dark rust-brown intermixed with a large quantity of black hairs, and the same color extends over the anterior half of the inner surfaces of the ears, the posterior half being light ful- vous or buff. There is a small. light spot behind the base of each ear. The shoulders and back between the lateral stripes are very dark grizzled iron-gray, with a sprinkling of buff or yellowish. The dark stripes are not perfectly clear black, and their ferru- ginous borders are not well defined. The median stripe extends from the occiput nearly to the root of the tail. The light stripes are dark buff intermixed with dark-tipped hairs. The sides are buffy- fulvous well sprinkled with black-tipped hairs. The rump, hips, and backs of the hind legs are dark rusty-brown. The upper surfaces ` Of the feet are ferruginous. The upper side of the tail is blackish, edged’ with hoary; the under side, deep hazel (almost chestnut), bordered with black and edged with hoary. This rich hazel of the under tail extends continuously forward over the anal region $ the genitals, where it terminates abruptly without shading off into the surrounding white. The under parts, from the mouth to the genitals, are clear buffy-white. Through the kindness of Mr. William Brewster, Curator of Mammals and Birds in the Museum of Comparative Zoology at Cambridge, Mass., and of Mr. F. W. True, Curator of Mammals in the United States National Museum, I have been enabled to €xamine the chipmunks contained in these collections. I am indebted also to Mr. William E. Saunders for the loan of a speci- men from London, Ontario, Canada. These specimens, together with my own (which in numbers exceed all the others combined), Constitute a very complete series of the Eastern animal from the region between Canada on the north and Washington, D. C., on the south. a : Comparison of representatives from the extremes of this range brings to light the following differences: The crown in typical- : orthern specimens varies from pale to bright rusty-fulvous, while im typical Southern examples it is dark rust-brown. — 240 Description of a new Subspecies [ March, The nape and the back between the median and first lateral black stripes are clear ash-gray in the Northern animal, while in the Southern these parts are dark iron-gray, more or less mixed with grizzly. In specimens from the Mississippi Valley, the same parts show a sprinkling of yellow-tipped hairs. The light lateral stripes are white, or but faintly tinged with buff in typical Northern specimens, while in typical striatus from the South they are strongly washed with buff, which color often deepens to pale fulvous posteriorly, and is further obscured by the admixture of a number of dark-tipped hairs. The sides vary from the palest buff (as in specimen No. 1200) or buffy fulvous in the Northern to dark fulvous in the Southern form. Northern specimens show a slight sprinkling of black-tipped hairs, which increase in number from the north southward till in typical striatus the admixture of these hairs very materially darkens the sides of the animal. In typical Northern examples, the pale buff of the sides fades so gradually into the white of the belly that no sharp line can be drawn between them; while in typical striatus, on the contrary, a very clear line of demarkation sepa- ` rates the two, the (comparatively) dark sides contrasting strongly with the buffy-white of the under parts, even when these parts are suffused with fulvous—which fact is due to the absence of black- tipped hairs from the belly. The upper side of the tail is much lighter in Northern speci- mens than in s¢riatus proper, though the hoary edging is more conspicuous in the Southern. This difference in appearance is due to the fact that the black subapical portion of each hair is much broader in the latter than in the former, and the subbasal fulvous portion proportionately narrower. The result is that in the Northern animal the pale fulvous zone shows through, while in the Southern the corresponding zone is mostly concealed by the overlying black. In typical Northern specimens the under side of the tail is buffy or buffy-fulvous, fading in the anal region - into the white of the belly; while in typical striatus the under side of the tail is deep hazel, which color extends forward around the anus to the genitals, where it ends abruptly without shading _ off into the surrounding parts. _ The dark spot above the tip of the nose is usually indistinct - and sometimes wanting in Northern specimens, while as a rule it is well marked in those from the South. The facial markings, 0% 1886, | of the Common Eastern Chipmunk. 241 the other hand, are more distinct in the Northern than in the Southern animal. These markings, however, vary so much in individuals in respect to clearness of definition that they may be dismissed as unimportant in the present connection. In brief, it may be said that the Northern animal differs from the Southern in the clearness and lightness of its colors, the black stripes remaining much alike in both; or, conversely, that the Southern is characterized by an intensification of all the colors, resulting in the darkening of the entire upper surface. Richardson, in 1829, seems to have been first to describe the Northern form, though he did not suspect it to differ from the Southern. Believing that the specific name s¢riatus belonged to the Asiatic animal, and assuming the American to be distinct, he called the latter “Sciurus (Tamias) Lysteri. (Ray.),” but was wrong in supposing that Ray had named it before him. Baird expressed the matter in a nutshell when he said, “ This author [Richardson] quotes Ray as the authority of this name, but it is, in fact, his own—Ray only referring to the species as Sciurus a Clar. Dom. | Lyster observatus” (North American Mammals, 1857, p. 295). Richardson’s account of the animal he had in view admits of no question as to its exclusive applicability to the present form, and his plate (plate xv), though uncolored, is equally unmistak- able. Furthermore, he distinctly states that his specimen came from Penetanguishene, which is on the north-east arm of Lake Huron, a region which, theoretically at least, ought to furnish most typical examples. His description was taken from “a recent male specimen, killed in April at Penetanguishene.” The portion of it relating to color runs as follows: r —The dorsal aspect of the head is covered with yellowish-brown hairs, which are mixed with a smaller number of black ones. There is a black spot near the tip of the nose. The eyelashes are black, the eyelids white; there is a dark- wn streak between the eye and the ear, and a broad, yellowish-brown stripe ex- tends from the nose, under the eye, to behind the ear, deepening in its middle to chestnut-brown. The anterior part of the back is hoary-gray, from a mixture of black and white hairs. The e rump, hips and exterior surfaces of the thighs are of a bright orange-brown color, mixed with a few black hairs. A dark dorsal line com- mences at the occiput, and reaches to within an inch of the tail. This line is wnish at its commencement, but deepens to black posteriorly. There are also, on each flank, two black lines. , which commence behind the shoulders, — to the hips, and are separated by a moa broad white stripe. All these stripes are 73 or less bordered with brown. The sides, beneath the stripes, ec a mixture © or gray and very light brown. The fur, covering the throat, chin, belly, and inner Surface of the extremities, is longer and thinner than that on the dorsal aspect, = os _ 242 Description, &c., of the Common Eastern Chipmunk.

There is no defined line of Separa- tion betwixt the colors of the back and belly.” Salas Boreali-Americana, Rich- ardson, 1829, pp. 182-183.) Hence it is clear that Richardson’s name /ys¢eri must be adopted as the subspecific name of the Northern animal. Following are diagnoses of the two races: TAMIAS STRIATUS TYPICUS.—Manus, 20 to 21™™ ; pes, 34 to 35™™ ; crown, rusty brown or grizzled brown; nape and back nearly to rump iron gray, sometimes mixed with grizzly; Ried dark ferruginous, sometimes almost chestnut; sides, rus- set fulvous, passing into ferruginous over the hips, and mixed with a variable quan- = of black tipped ode the fulvous (losing its black hairs and becoming paler) metimes encroaching upon the buffy white of belly and occasionally meeting irreg- fay along the median line below, but always leaving a well-defined line of demar- kation between the sides and belly; light lateral stripes strongly suffused with buff sometimes tinged with fulvous posteriorly; under surface of tail, mesially, dark fulvous to hazel, often very deep.

J. BY L. P. GRATACAP. Pe indurated and fissile shales that crop out beneath the superimposed masses of trap rock along the western bank of the Hudson river at Weehawken, Gottenburg and neigh- boring localities, have been frequently explored for fish remains. Their unequivocal position as Triassic slates, and the interesting developments made by I. C. Russel at Boonton, N. J., some years ago, in beds of an identical character, stimulated collectors to hunt here for similar fossils. As far as I know there is no pub- lished account of any success met with in the search, or indeed an account of any kind. Estheria in compressed and almost obliterated patches have been taken out, but the fish beds kept discouragingly out of sight. Mr. F. Braun, of this city, has recently revealed a large number of fish remains in the slates referred to, and has most successfully extracted specimens of considerable beauty. These specimens comprise almost whole fishes and numerous instructive fragments, while a few plant remains, tracks and rippie-marked blocks from the underlying sandstone have given to his discovery a more comprehensive interest, In general the locality established by Mr. Braun is about 800 feet south of the mouth of the tunnel of the N. Y. W. S. and Buffalo Railroad, which pierces the trap ridge known as Palisade mountain, a long exposure of basalt limited by Professor Cook as follows: “It may be said to start near the Highlands west of Haverstraw, in Rockland county. The range is continuous to Bergen point. It reappears south of the Kill von Kull on Staten island, and finally disappears near the Fish Kills. Its total length hn Ladentown, N. Y., to the Staten Island sound, is fifty-three miles,” Mr. Braun commenced his quarrying in a bed of slates directly underlying the trap rock which rises in perpendicular walls far above it, and found his fish and plant remains restricted to a nar- row layer of from three to four inches in thickness, and towards the base of the entire slate bed. An examination of the ledge, of which this bed formed a member, showed a succession of slate, vo L. XX.—NO. III 17 244 Fish Remains and Tracks in the { March, sandstone, slate and trap. At the bottom, forming a low shelf whose base: was buried in the alluvium, was.a slate group formed of closely compacted laminz of slate in conformable contact with a bed of sandstone, which at the line of union with the slate was granular and siliceous, becoming compact and feldspathic on its upper side, where it becomes almost fused with a second bed of slate, the fossil layer, above which rose the trap cliff. The expo- sure of the first slate bed had a thickness of five to six feet, the ' thickness of the sandstone was four feet, and that of the fossil _— a - Paleoniscus latus Redfd., Weehawken, N.

Two photographs were taken, _one of the ledge itself (Plate x11), formed of the three beds, and _ a second at the mouth of the great tunnel, some 800 feet north of this point, where the fossil layer of slate rock with its lines of bedding can be seen conspicuously meeting the trap, fissured by crevices of vertical cleavage (Plate xin). The first photograph was rather unfortunately invaded by a local group of sitters bear- ing no sensible relation to its particular object.

The fossil remains taken from the slate comprise casts and impressions of plant-roots or root-like fragments, the lobate divis- ions of an aquatic plant, an enigmatical nut displaying its coaly and black nucleus, and numerous fishes in various stages of pres- ervation, and in positions that seem to throw a light upon the local circumstances of their entombment. Mud cracks reticulate the slate slabs in ramifying lines, the silent witnesses to processes along the shores of an ancient Triassic estuary, identical with those that produce to-day the same markings upon a sun-baked bar. One of the best examples of the fishes in Mr. Braun’s col- lection, now in my possession, is shown in the foregoing sketch. I think all the fish remains I have are identical with this one as to genus and species, and it appears identical with Palæoniscus latus Redfd. On a specimen, other than the one figured, the dorsal fin shows the coarse raylets attached to the anterior spine, and its position, although quite far back, does not correspond to the insertion given for Catopterus. The fishes are found lat- erally compressed and usually straight, but in some instances the creature ‘has become doubled and turned over on itself as if en- trapped while wriggling in its contortions to escape again to the — water, which receding left it exposed upon a muddy flat. Many have become macerated, and the surrounding shale is Strewn with their scattered scales, whose disconnected marks gradually become closer in one direction, leading the eye toa formless cluster of scales and head-parts. Most of the specimens Suggest that the fishes perished in numbers and were buried be- neath later films of detritus as they lay motionless upon their sides. The locality so lately discovered may reveal more of interest both as regards these fish in their zoological status, the character of their habitat and the manner of their death. I have found in these slates lenticular masses of a pulverulent and highly car- bonaceous material which yielded seven per cent of combustible matter, and would doubtless have reacted for phosphoric acid. They seem connected with the organic occupants of the rocks, — and may have arisen through their decomposition. In the sandstone below this slate Mr. Braun has found impres- 246 Resemblances in Arts widely separated.

MASON. ROM the times of the earliest travelers down to the present y, we have narratives of the occurrence of the same inven- tions (implements), practices, modes of speech, institutions, theo- ries, and religious creeds and cults in regions wide apart. The older historians and ethnologists were wont to say that ? Read before the Washington Philosophical Society, Jan. 30, 1886. — 1886.] Resemblances in Arts widely separated. 247 similarity of human actions argued consanguinity in those who practiced them, that when the same phenomena occurred in two places they must have had their origin from the same race. Those who hold such theories are not all dead, as any one con- versant with recent literature well knows. It is quite possible also that among older thinkers there were other ways of account- ing for such similarities as I have mentioned. Before speaking of another explanation it is necessary first to examine more closely the old doctrine. Admitting that all like inventions had their origin from the same race, we have two pos- sible ways by which each one may have been planted in different parts of the world. An art may be so peculiar to a people that its presence argues their presence always, in which case the art may be said to have the same inventor and executor. An art may originate with a race or people, some of whom may carry the knowledge of it everywhere, or foreigners visiting that people may learn the art and carry it home, or it may, undesignedly on the part of any one, be diffused. In our day of illustrated books and papers there is no telling how far the tuition of culture may extend. In this second case the art has the same inventor, but not necessarily the same exec- utor or disseminator. Which of these two causes has been active in any case seems to me to be a matter of counting—of numbers. The same race of people would hardly move about over the world, plant them- Selves here and there, and forget all the occupations and customs of fatherland excepting one or two. Mr. Tylor told the Anthropo- logical Society of Washington that he found in the neighborhood of Philadelphia so much old-fashionedness belonging to England that he could almost imagine himself in the midst of an English village of the last century. On the other hand, the occurrence of a fac-simile of a Grecian temple, as Girard College, in Philadel- phia, where other examples of Greek culture are difficult to be found, is an evidence in favor of Hellenic influence, at least upon the architect and trustees of that building. 3 The other motive to the adoption of the same means for the Stratification of human wants or the exercise of human ingenuity, of which previous mention was made, is the identity of those wants and the instrumentalities of their gratification in all branches of the human family, including both the natural apti- 248 Resemblances in Arts widely separated. [March, tudes of man himself and the material environment out of which come the resources of gratification. Upon the principle that like causes produce like effects, it is nowadays argued that men will everywhere, under the same s/ress and with the same resources, make the same invention. We must carefully note that different grades of civilization and different ages of the world give variable significance to the words stress and resources. In each age and in each grade, natural, primeval aptitudes are intensified and warped by inheritance and tuition. Material environment is varied and intensified by ever accumulating historical information, refinement and science. Resemblances, therefore, by independent invention become rarer, as the circles of national and racial influence enlarge and cross one another. Before attemptling to lay down rules by which like human activities may be referred to one or another of the causes just named, the activities themselves ought to be closely scrutinized, in order that we may arrive at an intelligent definition of the wor resemblance, Aristotle enumerates four sorts of causes of actions: The tnaterial cause, ex qua aliquid fit; the formal cause, per quam; the efficient cause, à gud; the final cause, propter quam. With this classification as a basis we may regard human activities and the things associated with them from several points of view, as one example will shew. The Indian basket-maker there is plying her craft. She is the efficient cause of her art. Under other social organizations it would be the men, and in higher civiliza- tion it would be one of a small guild or trade, called the basket- weavers’ union. By her side are strips of grass, splints of root or osier, bundles of cane or rattan, either dyed or in the natural color. These arè — the material cause of her basket. She holds in her hand a bone, or ivory, or wooden awl or pricker; it may be also that a knife, rubbing stone and paint- brushes are at her side. These and whatever other tools she uses constitute the instrumental cause of her work. In her mind are certain forms of baskets and of basket-weaving related to her tribal art and to the structure of the vessel; others also arise spontaneously, and the resultant of them all is the formal cause of the work. -She has her peculiar way of putting her work together, of sit- 1886, ] Resemblances in Arts widely separated. 249 ting, of framing, stitching, plaiting, weaving, of placing her mate- rial into form for a fixed purpose: These constitute her manner of action, which we may call her processional or methodical cause. a Finally, the foregoing causes have- been set in motion with a view to function, to the uses. whereunto this basket is to be put— in a word, to the final cause. Moreover, to her art belong a tech- nical vocabulary, all sorts of lore and myths, and even social organization and sometimes religion are influenced by it. Now, what is true of one occupation is true of another. Each one of them, from the lowest to the highest, involves: 1, agent ; 2, material; 3, implement; 4, form; 5, process; 6, motive or function ; not to include others unnecessary to mention now. Again, it must not be forgotten that the materials, implements, forms, etc., of most activities, excepting the rudest, are the pro- ducts of other activities, and each may have had its six elementary Causes, giving rise to generations and genealogies of causes. Now, let it be especially noted that in each invention or art the resemblance may extend to only one of the six elements, or it may include two or more. Furthermore, resemblance may mani- fest itself only in some one generation inthe genealogy. If we read carefully the works of those who are constantly pointing out evidences of the migration of tribes or races, we shall see that their attention has been fixed upon only one or two elements of the art under scrutiny. The complication of causes in producing a result stands in the _ Same relation to the result that complexity of organization does to plants and animals. Those arts that involve the fewest causes, the shortest concatenations of causes, have the greatest chance _ of arising independently; while those that involve the greatest number of complicated and connected causes give the strongest evidence of absolute identity of origin. - Another consideration which we must not omit in this study is the natural relation between thi ngs and their uses; between the number of things which may perform a given function, between the number of functions which a given thing may perform. In human trades, languages, the organizations of society, the fine arts, moralities, the progress of learning, creeds and cults—the » bonds of union between the ends to bé attained and the number of possible ways of attaining each end vary immensely in - 250 Resemblances in Arts widely separated. [March strength and number. Admitted that all human arts whatever start from natural objects, endowments and relations, it follows that in their pristine condition men took the causes of their activity immediately from nature—flint flakes for knives ; sharp sticks for spears and spades ; gourds and conchs for music; ejacu- lations for words; consanguinity for social bond; animism for theology, and dreams for revelation. These are so natural and necessary that we need not be astonished to find men flying to them in emergencies and inventing over and over again all the devices and methods of the primeval world. If a stone knife has functions peculiar to itself, if cutting is dependent on stone knives, then the stone knife will often be invented independently. If almost any vocal combination will recall an idea; if almost any vocal combination may stand for innumerable objects, then the possibilities of associating any object with a particular vocal combination will be feebler, and similarities in language in differ- ent localities will be more likely to arise from the same people, either by migration or by literary influence. But words fly with such ease and rapidity over the earth that we are in quite as great a dilemma regarding them, whether we shall say that those who use them are of the same blood, or whether in one case they are evidence of tuition. Since we are thus almost always the sport of three rival theo- ries, I would prefer to adopt a new plan. Laying aside predilec- tions I would adopt the inductive method. There must be a great many resemblances in things from different times and places about which there exists positive information. Resemblance by independent invention being the least proba- ble, I would scrutinize with great care such examples to ascertain the degree of complexity in the things invented, which we are allowed to suppose. It is my pleasure to bring before the society two inventions about whose independence of origin there can be no question. One is a type of basket-weaving found only at Cape Flattery, in Washington Territory, and on the Congo. The _ other is the throwing-stick, occurring only in Australia, Brazil and Eskimo land. ioe The basket weaving may be called the bird-cage type, that is, _ a series of horizontal rods is crossed either at right angles of diagonally by another series of vertical rods, just like the wires 1" a bird cage, These rods are firmly lashed in place by a continu- 1886.] Resemblances in Arts widely separated. 251 ous coil of grass or splint, making a diagonal stitch in the front and a vertical stitch in the rear. Now this process is common enough in wattling fences, fish traps, etc., but only in these two areas did men and women hit upon the notion that this stitch would make the most beautiful and effective close weaving. Wherein is the similarity in the two areas? The two forms. of weaving stand thus: Alike in method or technique ; different in agent (women at Cape. Flattery, men on the Congo), in form, ma- terial and function. ; The throwing-stick is a device for launching a dart or harpoon too heavy for a bow or in situations where a bow would be incon- venient. The Australians have no bows; the Eskimo uses his throwing-stick in the kyak, where a bow would be inconvenient, furthermore his missiles are far too heavy for a bow. Wherein do these inventions resemble? In agent, material, form and func- tion; but not perfectly. In form they agree only in the funda- mental invention, a handle and a peg or hook to catch the end of the dart or harpoon. The Australian and the Puru Puru stranded on this, their minds never conceived that it could be altered or improved. The Eskimo, on the other hand, has developed a dozen species of throwing sticks, so distinct that they can be separated by types, as follows: The Greenland type...... Hooks on the harpoon shaft, The Ungava type Fiddle head at the hook. The Baffin WP we bea Broad and clumsy for bird spear. The Anderson river type. .Exceedingly primitive, all in one piece. The Pt. Barrow tpt: ssie Amphora-shaped The Asiatic type......... Primeval in form The Kotzebue type.......Razor-strap form, central index cavity. The Cape Nome type..... Pegged on the side, rude. The Norton sound type...Climax of detail. The Nunivak type..... .. Finger pegs replace cavities. The Bristol (variety) ..... A variety of Nunivah, but ruder. The Aleut type.......... Flat and wanting in detail. The Sitkan type ........,Elaborately carved. These types are explained and illustrated in a paper about to . appear in the first annual report of the National Museum. : If any one, therefore, questioned the relationship of the peo- ples now using this weapon, he would be allowed to compare only that of the Asiatic Eskimo, with that of the Australians. If he would A i the genealogies of causes which had led up to the simpler forms in the two regions, there would be no ground left for him to stand upon, and the case of independent invention would be clearly made out. o 252 Editors Table. { March, EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. The principles which underlie the doctrine of evolution are the unity of organization and the derivation of modern types of beings from a primitive germ. While the theory of descent has rehabilitated philosophy, the leading historians, such as Greene, Freeman and others, have studied and are studying his- tory in the inductive method, and, like the evolutional naturalist or philosopher, or social scientist, go back to the beginning of things historical, detecting, for example, in the early stages of German culture the germs of our democratic system of represent- ation and self-government. Another set of workmen, the philologists, have long and inde- pendently, perhaps, of any influence from naturalists, adopted the methods of the palzontologists and discovered a primitive Aryan prototype of certain of our more modern as well as so-called ancient dialects; and now come the students of the world’s alpha- bets, notably Dr. Taylor and Professor A. H. Sayce, who avow- edly confess their inability to work out lasting results without having recourse to modern scientific methods, particularly the doctrine of evolution from a primitive germ. It appears that the world’s alphabets are “all but the manifest developments of a single germ.” That germ was the hiero- glyphics of Egypt, the running form of which was the selected characters of the Egyptian hieratics. These were adopted by the Phcenicians, who carried them to Greece. The Greek alpha- bet took its Hellenic shape by the addition of four new charac- ters (p, z, ¢ and v), probably, Mr. Sayce claims, derived from the Hittites. Finally a great variety of alphabets belonging to dif- ferent ages and localities arose, and it was “not until about 400 B. C., when the local dialects began to yield to the ‘ common’ Greek of literary Athens, that the local alphabets also fell into disuse and were superseded by the common ‘ Ionic’ alphabet of twenty-four letters,” Mr. Sayce farther tells us that one of the Greek alphabets, the Euboeic, “was the source of all those which were employed in Italy, * * * * and modern research has now demonstrated, to use the words of Dr. Taylor, ‘ that all the Italic alphabets were developed on Italian soil out of a single primitive type.’ ” Using the identical words of a Darwinian botanist or zoologist, 1886. | Editors’ Table. 253 Professor Sayce goes on to remark: “In the struggle for exist- ence, the Latin alphabet alone survived among its Italian com- peers, and was carried, by the extension of the Roman empire, through the length and breadth of western Europe. Most of our modern European alphabets are its direct offspring.” In Russia and other Slavonic countries the alphabet was of Greek origin, as were the runes of our Norse forefathers. Professor Sayce even claims that “ the immense majority, if not the whole, of the alphabets used in the East are descended, like the alphabets of the West, from the alphabet of Phoenicia. The Hebrew, Arabic and Syriac are derived from the Phcenician, the Syriac being supposed to have been ‘the parent of the vertically written Mongolian and Mantchu.’” “In fact,” concludes Professor Sayce in his article on the origin of the alphabet in the Contemporary Review for December, 1885, “it is difficult to find any alphabet which cannot be affiliated to the Phoenician, widely different as the two may have become both in the forms of the letters and in the values they bear. Inter- mediate forms are continually being discovered, which bridge over the enormous distances and explain the transitions that time and space have effected. Even the Devanagari alphabet of San- skrit, whatever disputes there may be as to its exact pedigree, is generally allowed to be of Phcenician origin. With the exception of the cuneiform alphabet of the ancient Persians, and possibly One or two more which may yet lurk in obscure corners of the world, all the alphabets of which we know are derived, ultimately, from a single source. Utterly diverse as they are in their latest forms, the zealous enthusiasm of palzographists and inscription- hunters has succeeded in restoring them to their earlier shapes, in filling up the intervals which separate them from each other, and in showing that they are all but the manifold developments of a single germ. The history of the alphabet, in short, like the evan of its origin, is but an illustration of the doctrine of evo- ution on a large and easily tested scale. ‘Scientific paleography,’ to use again the words of Dr. Taylor, ‘rests on the assumption that no alphabetic changes are ever accidental or arbitrary, as was formerly assumed, but are the result of evolution taking place in accordance with fixed laws?” _ How vividly the language and methods of work employed by a scholars recall the language and methods of the philosophic iologists in their attempts to seek the missing links and ances- tral forms of life which complete and unite the chain of being! 254 Recent Literature. [ March, —— The bestiarians in Belgium have appropriately united with the antivaccinationists in the publication of a journal entitled The Friend of the People. In Paris and in Philadelphia the anti- vivisection societies have modified their titles so as to state that their object is to regulate, and not to abolish vivisection. To such a service reasonably executed, no one should object. How- ever our hopes of rational conduct on their part, are somewhat abated by the addresses delivered by some of their members. It is still asserted in Philadelphia, that no benefit to physiological science has been derived from vivisection!

Coutter’s Rocky Mountain Borany.—This neat manual, in its substantial binding, good paper and excellent typography, reminds one every way of the well-known Gray’s Manual, of which it is, in fact, designed to bea companion volume. It 1s intended for use in the region lying between the rooth meridian on the east and the Great basin on the west, and extending from the northern line of New Mexico northward to the British boundary. Its range, therefore, includes Colorado, Wyoming, Montana, Western Dakota, Western Nebraska and Western Kansas. There are several features of the book which are especially noteworthy. In it we have for the first time, so far as we are aware, merican manual of botany with the gymnosperms standing in proper relation to the angiosperms, The outline of the arrangement is as follows, viz: Series I. PH ANOGAMIA. Class I. ANGIOSPERMA. Class Il. GYMNOSPERMÆ. Series II. PTERIDOPHYTA.

We have no doubt whatever as to the author’s real views upon these points, and rejoice that he has, even in part, succeeded in securing a better arrangement and a more modern nomenclature, and only regret that it was not pos- sible to carry out in full the reform so well begun. We find by calculations made by us that the area of the region included in this book is but little less than that included in Gray's Manual. It is interesting to notice that the number of Rocky mountain plants is wonderfully near to that of the Eastern region. Doubtless when the Western region has been as fully explored, it will have a greater number of species than the Eastern. We ive below the comparisons for the different groups: ORDERS. GENERA.

Previous to the publication of these volumes Dr. Boulenger had given us in the Ann. and Mag. Nat. Hist., 1884, p. 117, a SYNOP- ' sis of the families of existing Lacertilia, as understood by him. The classifications of Duméril and Bibron and of Gray, still gen- erally in use, are regarded as unnatural, and the osteology and structure of the tongue as well as the presence or absence and structure of the dermal ossifications are put forward as characters of primary importance. In this respect Cope is largely but not entirely followed. Twenty families of Lacertilia vera are recog- nized, separated into three series, the first (Gecconide, Euble- pharidz) with smooth tongue and the clavicle dilated and loop- shaped proximally; the second without the latter character, while ore oS NI cease re I TE 1886. | Recent Literature. 257 the third differs from the others in the scale-covered structure of the tongue. The Amphisbznide are regarded as a degraded type of Teiidz, and are placed in the third subdivision, between that family and the Lacertide. The chameleons alone form the suborder Rhiptoglossa. The Uroplatide are discovefed to differ from the Gecconida in the proximally simple clavicles and other important characters ; the Scincoids of Duméril and Bibron are scattered through several families, in accordance with the views of Cope; the remaining Scincidz corresponding to Cope’s Scin- cide, Sepidze and Acontiidz ; the Zonuridz comprise the genera Zonurus, Platysaurus and Chamaesaura; while the Anguidz include Cope’s Anguide and Gerrhonotide. He admits Cope’s family Aniellide, regarding it as a degraded form of Anguide. A fam- ily Gerrhosauridz is established for Gerrhosaurus, which is placed near the Scincide; the Anelytropide are regarded a degraded type of the Scincidæ, and the degraded genus Dibamus is, among the scale-tongued lizards, the equivalent of the Aniellida in the smooth-tongued series. Of this system it may be said that it is a great advance over any that has yet been adopted in any European country. There are, however, a good many important characters of the skeleton which have not been used by Dr. Boulenger, and which give ground for a further subdivision of the order Lacertilia. The affinities of the families cannot, in fact, be estimated without th The, form of the prodtic bone is one of these, and the enclosure or non-enclosure of the olfactory lobes of the brain by the frontal bones is another. The mode of articulation of the occipital sclerotome presents important differences. Some of these characters divide his group second into groups of equal value with his groups 1 and 111; and others indicate a greater difference between the Amphisbzenians and the Teide than Dr. Boulenger admits. The composition of the ramus mandibuli affords impor- tant characters, so as to distinguish readily the Anolide and Acontiidz, families not admitted by Boulenger. This work is, however, the best we now have on the subject, and will give a great impetus to its study. A second preliminary paper is devoted to the geographical dis- tribution of the Lacertilia. He notices the parallelism, first noticed by Wagler, between the Agamidæ and Lacertide of the old world and the Iguanide and Teiidz of the new. The Cen- tral American fauna presents a greater variety of types than South America, as it has representatives of every one of the ported by the Lacertilia, which range also according to longitude rather than latitude. ey 228. 4 Recent Literature. | March, HartMan’s AnTHROPOID ApEs.—The author is well known asa special student of the apes, and has given us in this book per- haps the most authoritative and judicious work upon these crea- tures yet published. The illustrations are in nearly every case of value, and the facts are presented in a clear, simple style which adds weight to the author’s views. As we see nothing to criticise, we will draw the reader’s attention to some of the author’s state- ments and conclusions. The discussion on the ape-like characters of the lowest human tribes is of much present interest. Hartman shows that among some human races “it is impossible not to recognize a purely external and physical approximation to the simian type.” Yet old specimens of apes, especially the gorilla, differ more from man than the young, and the author is strongly of the opinion “that man cannot have descended from any of the fossil species which have hitherto come to our notice, nor yet from any of the species of apes now extant.” He adopts Vogt’s view “ that both types have been produced from a common ground-form, which is still more strongly expressed in the structure of young speci- mens, because the age of childhood is less advanced.” Hartman adds: “ This supposed progenitor of our face is necessarily com- pletely hypothetical, and all the attempts hitherto made to con- from a common ancestor. On this ground as well as from ana- tomical considerations, we should refer man to a distinct, special family. = Kane’s HAND-BOOK or European Butrerriies!—A handy little book is this for the butterfly-catcher. The introduction gives the best localities and the distribution of species, methods of capturé and of preservation when captured, apparatus, a full glossary of terms, arguments on seasonal dimorphism, etc. This is followed by fifteen plates and 149 pages of generic and specific criptions.

The faults which an evolutionist may find in it will endear it to all those who instead of believing that function precedes structure, put the latter first and make it push its own motor. It seems strange that a working naturalist should suppose that birds are supernaturally fed, and should ask “ when are they starving or wanting sustenance ?” as though half- starved birds are not abundant in winter, and as though none per- ished! The book is wordy, or as its author would probably say, one of the most remarkable characteristics of the volume is its extraordinary verbosity. Everybody is quoted; Wilson, Audubon, Thoreau, Coues, Bur- rough, Wallace, Dall, Maynard are presented in long paragraphs ; there are bits of many a lesser light of zoology, and several “dis- tinguished taxidermists” figure in the pages. here is a good deal of information in the book, and moral les- sons and quotations are quite as prominent as ornithology.

GENERAL.—Dr. T. Fischer, in Petermann’s Mittheilungen, main- tains that when oceanic agencies alone have formed the coasts, it consists of a succession of arcs, in the case of steep coasts with a short, and of flat coasts with a long radius. Where the coasts exhibit other features, other causes, as movements of the earth’s crust, are either more powerful or are very recent. Arctic Recions——The Danish expedition to the east coast of Greenland returned to Copenhagen, Oct. 2d, after an absence of nearly three years. Besides the collection of valuable scientific material, Lieut. Hahn has made some important geographical and ethnographical discoveries. He wintered between latitudes 65° and 66° and reached 66.08° N., the highest point yet visited by uropeans on the coast. He has named the stretch of coast explored Christian IX’s land. The area of Store Baergefjeld, in Arctic Norway, has been rep- resented as an immense glacier field. The observations of Chas. \abot show that there are nearly seven secondary glaciers, hardly Passing beyond the stage of névé, and that their total area does not exceed six kilometers. The region is not a plateau, but to the north a mountain mass with summits nearly 6000 feet high, and averaging 3600 feet; and to the south a densely w table-land cut up by cajion-like valleys. Rabot has also found that distinct chains of mountains, reaching a height of more than 3000 feet, exist in the Kola peninsula, between the White sea and fe IC The district is usually shown as a plain, broken "This department is edited by W.

On the whole, however, his statistics prove rather the need for settled success in Liberia. Lieut.Wissman’s Expedition —Lieut. Wissman’s expedition down the Kassai throws new light on the geography of the Congo basin. The Sankuru, or lower course of the Lubilash, unites with it by ‘two arms 830 and 1000 feet wide; a river which Lieut. Wiss- man believes to be the Loangwe, though at its mouth it is known as the Temba, flows in lower down; and still lower the great Cuango and the Mfini from Lake Leopold unite their waters with it. Below the Sankuru the Kassai is 3300 yards wide, and yards or more, and is dotted with islands and sand banks. Its lower portion, known as the Kwa, is narrow, not more than 45° Lulua the native name is Savié. The natives here are Barkub on the right bank, Bashilelé on the left. Lower down, below - he Sankuru, reside the Badinga and Bangodi, and stiil lower the Btakuta, who were hostile to the explorers, and are reputed canni- bals. Still nearer the junction of the Cuango are the Baduna. 1886] Geography and Travels. 263 African News.—The native population of the Gaboon region is, according to Dr. Lenz, being rapidly driven towards the interior by the Fans. The Germans have annexed the country lying behind the French possessions at Great and Little Popo, on the Gold coast. M. G. Angelvy, a French engineer in the service of the Sultan of Zanzibar, reports that he has discovered coal of excellent quality on the Lujenda tributary of the Rovuma. The great drawback is the distance from the coast, all the more to be regretted since beds of siderite lie near. The Rovuma, though 2000 feet wide, is but a foot to a foot and a half deep. The sul- tan intends to work the coal-beds, and to construct a road or rail- way to Lake Nyassa. Sir John Kirk, in a letter accompanying that of M. Angelvy, states that the coal region lies sixty miles south of the latitude of Delgado bay, and a question of inland frontier is therefore likely to arise between the Sultan of Zanzibar and Portugal. At Tunis a modern French town is being built between the native city and the lake. Land is being rapidly brought under cultivation, taxes reduced, roads constructed, and the country in every way improved. . Moller has proved that the peak of St. Thomas is the highest Iand in the island of that name, and is 2142 meters high. The November Bulletin della Società Geographica Italiana contains a letter from De Brazza, describing a voyage undertaken from Brazzaville to the Licona or Ncunda. The name Congo is not known by the Apfurus and Bateke, who speak of it as the Great river. The village of Bonga at the mouth of the Alima is large and picturesque, it is intersected in all directions by canals, and the houses, some meters long, form streets. Down the wilderness of canals is brought the large quantity of manioc grown upon the Alima, for the supply of the natives of the Congo banks, which in this part are unfitted for the growth of manioc. De Brazza says that it will be half a century before the labyrinth formed by the various channels of the Congo above Stanley pool is correctly mapped. - For eight days, he says, “ we believed we were on another river, and found after all that we were on the Congo.” The Apfurus and Bayansi are the same people. H. Entz and A. Mer have, after a careful study of the voyage of Hanno, the Carthaginian, come to the conclusion that it terminated at Fernando Po. Thymate- nion 1s identified with the town of Mazaghan, and the promontory of Soloé with Cape Cantin. The Lixus is by Mer identified with the Senegal, by Entz and others with the Draa.

The German government has published the annexation of the territory called Usaramo in west equatorial Africa; and has occupied Dar-es-Salam, a port opposite to Zan- zibar. The King of Dahomey has abolished human sacrifices in virtue of a treaty entered into between him and the Portuguese governor of San Principe, and a Portuguese protectorate is by the same treaty established over the sea-coast of Dahomey. Asta—Southern India—From some notes by Col. B. R. Branfill, it appears that Gzat means a pass and that monsoon is derived from the Arabic mausim, which means season.

March, April and May are the hot season of Southern India, the north-east monsoon succeed- ing it. The south-west monsoon parts with its moisture on the table-land of Mysore. The north-east monsoon fills the rivers and tanks of the drier Carnatic plain to the east of the ghats. The ghats are not very high, and when viewed from the table- land enclosed by them, seem rather a battlemented parapet than a . A leading feature of the western ghats is a long easy slope, crested with forest, leading up to a cliff overlooking the coast-plain.. Such a cliffsummit is called a Kadure-Mukh or horse-head. The eastern ghats have no such well-marked line of precipices as the western. Most of the drainage of Mysore, which undulates from two to three thousand feet above the sea, is to the Mysore, the largest some twenty miles around. The River Cau- very is thus utilized throughout the province. On it are situated the former capital, Seringapatam or Srirangapatnam, which is now deserted, and is a pestilential wilderness, and the ruins of the more ancient capital of Talkad, now buried in sand save only the pinnacles of the temples. In the Wainad or open country of the western highlands, south of Coorg, gold-mining has been com- menced, and there are many traces of ancient workings. SoS. Be of the Wainad lies the nearly isolated plateau of the Nilgiri hills or Blue mountains, rising on the western edge to 8000 feet or more, while Dodabetta, a conoidal mass with steep slopes covered with grass and woods, rises from its centerto a height of 8640 feet. These hills are the home of the Todas. The Nilgiri hills, though separated from the main table-land of Central India by the Moyar ravine, form really its southern termination. South of them is the Palghat gap, leading from Malabar to the south-central lowlands of Coimbatore and Salem. South of the gap the mountains rise. 18386. ] Geography and Travels. 265 again as the Anamalai or Elephant hills, and farther south, the Tra- vancore hills. These are a true mountain range, rising directly on all sides from the lowlands, and are steepest on their eastern: slopes. The highest measured point, Anamudi or Elephant’s brow, is 8840 feet above the sea, and the loftiest known peak in South- ern India. This range, called also the Southern ghats, ends at Cape Comorin. To the east of the Anamalai hills lies the lofty plateau of the Palani hills, in two steps, the upper 7000 feet high. Groups of similar but minor masses of hills are met with at inter- vals eastwards and northwards, surrounding the lowlands of Coimbatore and Salem, perhaps once the seat of a former inland sea. South of the Palanis is a large tract of mountainous wilder- ness, occupied only by wild animals and wild men of the lowest types, who go unclothed, and feed on such fruits and roots as they can scratch up with their fingers. They can make a fire, but sel- dom do so, and gather cardamoms, honey and other wild produce to exchange with their more civilized neighbors for salt, grain, and a little cloth to adorn their women.

All the rivers of Southern India tend to shift their mouths northwards from the action of the ocean rollers. The Coromandel coast is marked by a line of sand-hills with lagoons here and there on the landward side, and there seems to be an advanced line of coast in course of formation several miles out to sea. There is much coral in the Gulf of Manar. Besi the changes occurring on this coast from constant causes, storm waves have destroyed many ancient cities and ports.

We need not believe that this gulf was formed by any sudden catastrophe, for there is no reason to doubt that the sea conquered the land by the same methods and at somewhere about the same rate that it encroaches now, and that therefore its advance over many thousands of square miles of zerra firma would be an exceedingly lengthened process. We cannot gauge the time this occupied, but we know that since the appearance of man Southampton water has been formed, and a tract between Alum bay and Studland, some fifteen miles long and five or six miles broad, has been swept into the sea, and several species like the mammoth have become extinct. The rate of the encroachment depends mainly on that of the subsidence and the original height of the land, but what has here been effected in a subsidiary area serves to show roughly how vast a time must have been needed for the chalk sea to have crept from Kent to the Crimea, and covered the enormous area of Europe over which its traces still remain. As the land subsided and became sea, blue and green muds were thrown down, to be succeeded in due course by the deeper deposits of chalk ooze.

But when we reach Aix-la-Chap- elle, we find the chalk and greensand resting upon beds contain- gams. Nor does the 1200 or 1400 feet of vertical chalk remaining in our area at all represent the completed formation; for, as the prolonged subsidence finally ceased and gave place to an equall slow elevation, all the lessening zones of depth would travel back with the receding ocean, and leave a series of zones inversely arrang- ed tothat preservedto us.

The Eocene seas from beginning to end of the period were ceaselessly engaged in this work, and their enormous deposits of flint shingle mark how much of the chalk had fallen a prey to them. Nor has the chalk enjoyed any respite from the work of destruction down to the present day, so that what now remains isa mere fragment of what once existed. It was during the in- terval that elapsed between the formation of the newest chalk now left in England and the oldest Eocene that dicotyledons were introduced, and our existing flora practically came into existence. - All the Upper Cretaceous floras of Europe also flourished during this interval, but we cannot say, with our imperfect record, exactly the order in which they came in, and must be content to regard them in a general way as far newer than they appear to be strati- graphically. The entire American Cretaceous series should, per- haps, also be placed somewhere in this interval, though those well qualified to judge regard its commencement as dating from an older period. Without this digression we could not have formed an adequate idea of the meaning of the “ Cretaceous period” and So realized that the so-called Cenomanian and Turanian floras of Europe may belong to a completely different epoch to that represented by the same horizons in Kent and Sussex, — F., S. Gardner. r j 1 Š j i bers viou American Ka of Natural a Hy L | No. 6, r 7 ; 270 General Notes. [ March, nary notice: “ An American Silurian Scorpion,” under the name _ of Paleophonus osborni. The animal is no doubt a real scorpion, and not an Eurypterid; but as a few of the characteristics ascribed to it by the author would seem to remove it very far from other scorpions and especially from the Palzophonoide, to which it appears to me to be closely related, I venture to offer a few obser- vations on this arachnid, or rather, on Mr.Whitfield’s interpretation of certain points in its organization. Of course I give no other weight than that of mere suppositions to the opinions I am going to express, being fully aware of the difficulty and perhaps rashness of offering criticisms on the description of a rather badly preserved fossil, without knowing the “ corpus delicti” from actual inspection. According to Mr. Whitfield, the abdomen (preabdomen) of his scorpion is provided with sx long and broad ventral plates, and if this were true, this animal would of course be so different from the body in front of the plate in question. But to me it does not seem necessafy to admit that Proscorpius differs in so high a degree from other. known scorpions. I strongly suspect, that all that is seen of the abdomen in Mr. Whitfield’s specimen (with the exception only of the narrow border to the left, and, perhaps the posterior part of the equally narrow right-hand border) is formed exclusively of the dorsal plates. The whole upper side of the abdomen is broken or cracked longitudinally; the narrower, right-hand part, considered by Mr. Whitfield to be formed of the inside of the ventral plates, has perhaps an appearance different from that of the rest of the upper surface, only from having been more strongly depressed and crushed, and the apparently slightly greater lengths (in the antero-posterior direction) of the right hand parts of the plates would seem to depend on the same cause. This interpretation easily accounts for the circumstance that in Mr. Whitfield’s specimen the articulations between ad the “ven- tral g plates (not only between the posterior ones) are direct con- tinuations of the articulations between the “ dorsal ” plates, which is not the case in other, at least not in recent, scorpions, In these, in fact, the articulations between the first two or three dorsal plates do not correspond to or are continued by articulations Oñ 1 In Science, Vol. vir, p. 87 (July 31, 1885). sister catia alana amma 1886. ] Geology and Paleontology. 271 the ventral side of the body; for in these and perhaps in all scor- pions, the dorsal plates increase in length, counting from front backward, so that the first plate is the shortest of all; whereas (at least in recent scorpions) the first ventral plate is /onger-than the following ones, corresponding in length and position to ‘wo or even three (2d and 3d, or 1st—3d) dorsal plates taken together.’ If the above given interpretation is, as I believe, the right one, the want of sfzracu/a on the plates needs no further explanation” Mr. Whitfield thinks that, whereas modern scorpions carry the tail (postabdomen) arched upward over the back, Proscorpius, and also Palzeophonus, carried it inthe opposite way, or curved down- w This would indeed be a character of fundamental impor- tance in distinguishing the Silurian scorpions from all other members of the group; but to me it is impossible to find any stringent reason for adopting this strange hypothesis. In the first place, it would seem that the animal’s gait would become exceed- ingly difficult and awkward, if it were to walk with its tail curved under the body ; and when it wished to kill, with the sting, the prey which it had caught with the hands of the palpi, it would ly be obliged to thrust the palpus with the prey between its legs, under the body, in order to bring it within the reach of the sting—no doubt a difficult performance for the animal. That in the embryo of scorpions the tail is bent under the body, is of course no reason for believing that the tail retains that position after birth, in the earliest or Silurian species, rather than in Car- boniferous and recent ones. As to Palzeophonus, I do not enter- ‘eophonus nuncius described and figured by Professor Lind- trom and myself’ The basal joints of the tail of this animal are destroyed but must have turned their upper or dorsal surface upwards, as they have left the impression of their ventral part on wus" a specimen of Buthus 5-striatus Hempr. et Ehr., for instance, whose abdo- of cpreabdomen) is 2414™™ long, the length of the first ventral plate is 6™™, that 2E ñrst three dorsal plates taken together 5%4™™. oot if the plates in question really were ventral plates, the first (or sixth, whe Mmea behind forward) would from its position seem to correspond to the z ween ‘ f of int segment of the abdomen, quite as the plate between the combs is the sternite Bo second segment.

In the Scotch alezophonus described by Mr. Peach,! which is turned upside down, we consequently see that the basal joints of the tail turn their ventral part upward and that the last joints are viewed obliquely from above, As to Proscorpius the impression one receives from the figures is, that the tail shows the dorsal surface of at least three of the four joints still preserved, just as would be expected. Mr. Whitfield says, however, that it shows, of the upper or dorsal surface, but “ the inside of the ventral or lower field’s specimen.

But besides this, there are several other reasons for doubting that Pro- scorpius belongs to the Dionychopodes. In Palzophonus all the joints with the exception of the last, are cylindrical or nearly so; in other scorpions the “a is compressed and convex longitudinally on the under side; and in this respect Proscorpius appears to have resembled Palzophonus and not the Dionychopodes. The tolerably well-preserved leg of the first pair of Proscorpius seems to show that most of the joints of the legs have been compara- tively short in this animal, and in this particular also it resembles Paleophonus and differs trom the Dionychopodes. The “ crowd- ing forward of the limbs and appendages” depends on the shortness of the posterior cox, and isa characteristic that distinguishes Pro- scorpius from the Dionychopodes, but not from Palzophonus. (It is not probable that Proscorpius differed from other scorpions inthe number of the joints of the legs; if we assume that in the best preserved leg of Mr. Whitfield’s specimen the first joint or coxa is concealed by the margin of the cephalothorax, and that the leg is broken at the base of the last joint, it would seem to con- sist of seven joints, quite as in all other scorpions.)

An additional reason to those given above for removing Proscorpius from the Carboniferous Eoscorpioide, and for refer- ring this genus to the Apoxypodes, fam. Palaophonoide, may be found in its being, geologically speaking, almost contemporary with the Palzophoni, belonging, like these, to the Upper Silurian formation. As the Palzophoni, and all other more recent scor- pions, are undoubted land-animals and air-breathers, and, as no traces of branchiz have been shown to exist in Proscorpius, there is, I believe, no serious reason for considering that this scorpion 1s an aquatic animal, or that “ we have here a link between the true aquatic forms, the Eurypterus and Pterygotus, and the true air- breathing scorpions of subsequent periods,” as Mr. Whitfield sup- poses. Very strange, also, would it be, if the connecting link between the gigantic Eurypterids and the scorpions should be formed of such a little creature as Proscorpius osbornei, one of the smallest scorpions hitherto known—especially as this diminutive scorpion lived contemporaneously with the Eurypterids,—7.

The bones were found in Ely cave, Lee county, Virginia, one of the oldest of a group of cav- erns in limestone of Cambro-Silurian age described by Professor Shaler, of the geological survey of Kentucky. In general form the new dog was'a short-limbed, heavy-bodied animal, resembling in its proportions a badger rather than a dog. The skull has not been found.

The area of the tin-producing region is being constantly extended by new explorations, so that its limits cannot yet be definitely fixed. In addition to its occurrence in the rocks the mineral is also known to exist as “stream tin” in the water courses leading down from the hills into the surrounding plains, PETROGRAPHICAL News.—Feridotites—The rocks of this class belonging to the “Cortlandt series” on the Hudson river near Peeks- kill, N. Y., are divided by Dr. G. H. Williams! into hornblende peridotites (Hudsonites of Cohen), and augite peridotites (picrites of Tschermak). The former are characterized by the structure so well seen in the case of “ Bastite” or “Schillerspath,” and called by Pumpelly and Irving, “ luster-mottling.” In the present instance this structure (for which the author proposes the word fozcilitic) is due to the inclusion of olivine, or its alteration product ser- pentine, in hornblende. This hornblende is without crystal form and is filled with sharp little transparent crystals and opaque black needles. These latter occur also in the olivine and are identical with those which Judd? considers as of secondary origin. This — view the author of the present paper combats. He thinks they are substances extruded during crystallization as incapable o forming a part of their host, like the silicates in metamorphosed limestones, The hornblende peridotites pass, by the assumption of diallage, into the augite variety. Occasionally these become Schistose as the result of the action of great pressure.

The varioles are composed of a central kernel of about the same com- position as the rock. Surrounding this is a zone sometimes of calcite, sometimes of quartz, in which the mica occurs. Towards its inner side the mica is arranged in concentric layers, with con- siderable calcite or quartz between. The central portion contains only calcite and mica. Toward the outer side the calcite dimin- ishes in quantity and the granitic materials take its place. The exterior portion of the variole is composed almost entirely of _ feldspar and quartz, in which the biotite is concentrically arranged, while the calcite occurs only in isolated grains and rhombohedra. The calcite is regarded as an original constituent, since it is found included in the other minerals, and the varioles are supposed to be concretions.

He attributed it to the intergrowth of foreign crystals, but did not suggest what might be their nature.

It was . found to consist of little hemimorphic crystals of rutile elongated in the direction of the vertical axis.

These are formed endogen- ously upon the best nourished parts of the Cuscuta stem, and also upon the parts which bear the haustoria, where the host-plant and parasite are in immediate contact. The rudimentary shoot-buds are formed beneath the cortex of the Cuscuta stem, and break through in a manner similar to the lateral roots of vascular plants.

It makes its appearance first on the lat- eral roots of the young seedling, and is constantly being replaced by fresh formations on older roots. Dr. Frank found this struc- ture invariably on every root examined of trees belonging to the Cupuliferze, also occasionally on Salicaceæ and Conifera, but never on woody plants belonging to other natural orders, nor on any herbaceous plant. It is quite independent of the nature of the soil.

This is in accord with previous _ observations of the author on similar round bodies seen on the point of escaping from a Podosphenia, and with observations of Rabenhorst and O’Meara. The fact that the diatoms in which these bodies were observed had previously been treated with boiling sulphuric acid with addition of potassium chloride, shows conclu- sively that the round bodies seen to escape from living diatoms are not Infusoria or other organisms fortuitously collected round and demonstrates at the same time that, from the first mo- ‘ment of their existence, diatoms must be provided with a sili- _ C€ous coating, though it may be of extreme tenuity. It would seem from these observations that diatom may assume the function of a sporangium, producing in its interior embryonal forms by — which the species is reproduced, and which ultimately acquire the _ form and approximately the size of the mother-frustule. In connection with this subject, Mr. F. Kitton states (Jour. _ Quekett Micros. Club) that he found on carafes of water a film _ composed entirely of frustules of Achnanthes linearis ; but on filt- _ ering the water, these were never found on the filter-paper, 2No _when the filter-paper was boiled in decarbonized sulphuric acid, m Aa a a er 1886,] - ...

The wings of these insects and of the winged forms of Aphides are used chiefly as parachutes. The coxa of the limbs coalesce with the thorax, and the tarsi are two-jointed, bearing a pair of terminal claws. The hind-limbs are specialized for springing. The first abdominal somite of both sexes is added | to the metathorax to enlarge the springing-gear; the second abdominal somite forms a short stalk for the abdomen, and the ] terminal abdominal somites are so modified as to have misled the systematists. In the male the tenth somite seems to be in- serted on the eighth, as the ninth has only its ventral part devel- oped and ends the abdomen, whilst the tenth, bearing the anus and penis, is reverted dorsad. In the female the ninth somite 1s discernible only by its appendages, and the tenth isa roofing dorsal plate (the upper genital dorsal plate of Low) bearing in its center the anus fringed by wax-glands. Thus in both sexes the is typical number of ten somites can be found. ne The circum-anal wax-glands are in the larve of both sexes; and wax-glands producing wax-fibrils are present on other parts. Wax-particles sometimes cover the larvae, protecting the back from excrementitious matter. Some larve (Psyllopsis) have spear-shaped wax-hairs ; the larva of Trioza has a marginal row : of leaf-like wax-plates. All the wax-hairs arise like chitinous oe hairs from large hypodermal cells, which have vacuoles presuma- bly filled with the secretion-fluid. = The stigmas of the tracheal system are denticulated on each = side, and have a self-acting closing apparatus (not as described ~ by Landois).

This is probably for expiration. Inspira- tion is effected by the mere elasticity of the trachea, and the _ stigmatic valve closes by its own elasticity. The will of the in- = sect does not control these movements.

The compound eyes are well described by Viallanes (Ann. des Sci. Naturelles, 1882) for Musca. In Psyllidz they are somewhat simpler, having (1) at the surface numerous separate lenses of the cornea, slightly biconvex, (2) below them a layer of crystalline cones, often brownish, (3) next comes a dark layer of rhabdites forming the retina; each rhabdite being a slender truncated cone, narrowing inwards.

The antennal nerves run straight back to the antennal lobes (a/), whence some fibers run forwards to the central region of the brain. The “central body” has been described by investigators as a fan-shaped organ. Packard, after Newton, described it as a half- moon-shaped body, concave backwards and separated by a net- work of fibers from the brain, and supposed it to consist of modi- fied,cells. In Psyllidz it is bean-shaped, consisting of granulated matter not at all isolated from the surrounding parts of the brain, but receiving fibers from and sending fibers to the other lobes, and is nothing more than a central commissural system, its cell- like elements being the cross-sections of fibrous masses. 4 he mushroom-bodies, described by authors, are found in Psyl- lide only in a rudimentary form, being some thick masses of ganglion-cells in the upper anterior bor- der near the median line, whence bundles _ of fibers run backwards. : Taken as a whole the brain, with its connections with procephalic ganglion- masses, subcesophageal commissures and ventral nerve-cord, and various lobes in its own mass, is complex; and it !s scarcely possible to join sections made in different directions into a unity, SO aS to get its real structure.

This is the structure also in Coccide, as Dujardin and Mark shew [and is well seen in the larval seventeen-year Cicada.—G.M.]. The cesophagus is narrow, extending as far as the abdomen, where the stomach and beginning of the mid-intestine coalesce with the hind-intestine (Fig. 5), the two parts winding round each other in several turns. This coalescence is caused by the contrac- tion of the mid-intestine. Mark shews that in Coccide the ar- rangement is different, the end of the cesophagus and beginning of the stomach having a small winding loop which is received into a sac formed by the hind-intestine. This latter is also the way in Cicadidæ. The malpighian vessels are four, short and dis- tinct, their ends running into a suspensory ligament. They are wanting in Aphides and Chermetide.—G.

Usually the two elements unite early in the embryo. It is possible that a proatlas existed in Rhynchosaurus Owen, a reptile very nearly allied to Sphenodon (Hatteria). Sphenodon has rudiments of the proatlas, as shown by Albrecht;* therefore the same bones ought to be present in Rhynchosau- rus; this seems to be confirmed by a note by Owen? on this rept tile. “ A small flattened triangular plate, which adhered to the pos- terior part of the skull, was suspected by Dr. Ward to be a tooth; it appeared to me, from the character of the exposed surface, to have at least equal claims to be regarded a dermal scute. In pre- paring the mold of the cranium this part was detached and lost, a circumstance which I have much regretted, since it prevented my applying to it the test of a microscopical examination In his detailed ape ue of Rhynchosaurus, eee, does not mention this poin I believe it oni that the small flattened TAREA plate, “which adhered to the posterior part of the skull,” represents a piece of the proatlas. It is probable that the proatlas is present also in the Proto-. rosauria, which have many characters common with Sphenodon. Il. Atlas and Axis—The centrum of the atlas is always repre- sented by the odontoid process of the axis, and can be separated | easily in the Crocodilia. The piece below the centrum of the atlas, supportin g the neural arch of that vertebra, is the Oe pophysis, between the proatlas and the atlas The hy papophysis between the atlas and axis is probably co- ossified with the anterior and lower part of theaxis-centrum, asin irds and some dinosaurs. There seems to be a great confusion in the determination of the ribs belonging to the first vertebra in the Crocodilia, and’even about the true nature of these verte- bre. Koken’ says, 1882: “ Es ist erstaunlich und befremdend, _ wie sehr bei diesen sonst so conservativen Thieren die Ausbildung der ersten Halswirbel, und zwar in wesentlichen Punkten, differirt.

All reptiles possess the hypapophysis (unteres Schluss-stiick) of the atlas, and it is quite injudicious that Ludwig and Koken could deny the existence of such an element in an alligator and a crocodile from the Tertiary. i The matter is very simple. Ludwig described the true hypa- pophysis of A. darwini as the centrum of the atlas; the axis centrum _ . + the odontoid process as the centrum of the axis. Ludwig says = , that the odontoid process of the axis is wanting in C. ebertsi, but he describes it. He makes something very remarkable out of its separation from the axis. He did not find the hypophysis, and therefore he says this element is wanting. There is no doubt whatever that the atlas and axis of Alligator darwini and Crocodilus ebertsi possessed the same structure as the living alligators and crocodiles, oe Koken finds similar difficulties in the articulation of the ribs a (p. 809). “ Die zum Epistropheus gehörige Rippe ist: bet den lebenden Crocodilinen gegabelt und gelenkt (nur mit dem Capi- tulum) zwischen Epistropheus und Dens Epistrophei, mehr am _ lezteren. : “Bei Crocodilus ebertsi ist sie ganz auf den Atlas-K6rper über- gegangen, bei Alligator darwini trägt degegen der Epistropheus 3 die Rippe, bei beiden ist sie einfach. ee “Bei Enaliosuchus setzt sich die einfache Rippe an die Dia- = > pophyse des Epistropheus, während die Parapophysen keine -, Rippen stützen. ; “ Bei Teleosaurus ist sie gegabelt und sowohl an Diapophys¢ wie Parapophyse inserirt. 7 “Bei Teleosaurus findet sich ferner ein drittes Rippenpaar, -~ welches intervertebral zwischen Atlas-Korper und Epistropheus | articulirt.” : If these characters are true, we have to abandon the value oA | : : Siete, chee morphology.

Crocodilus ebertst shows the same conditions as A. missis- sipplensis. . In Alligator darwini the axis-rib is connected with the atlas- center. Ludwig, considering the atlas + axis as the axis, says that it articulates with the axis. 3. In the Enaliosuchus-axis a diapophysis is present. Koken believes that Enaliosuchus has a simple rib connected with this dia- pophysis. This can not be correct; if the diapophysis is present there must be an articulation for the tuberculum of the rib. The tuberculum never disappears before the capitulum. I believe that in Enaliosuchus (if it really belongs to the Crocodilia) a complete rib was developed in the axis, the capitulum articulating with the - well-developed diapophysis, the tuberculum with the axis-centrum or with both the axis and atlas, or with the atlas alone. This face will probably be found if the atlas-rib is removed. In the Teleosaurus-axis the diapophysis and the parapophy- sis are developed and the ribs two-headed. Deslongchamps describes an additional rib connected with the atlas-center, but he figures no articular surface for this rib on the atlas. It is a morphological impossibility that a rib should exist between the ribs of the atlas, connected with the hypa- pophysis, and that of the aris. At first when I saw Deslongchamps’s figures I reached the conclusion that the axis-rib had entirely disappeared in the living Crocodilia, and that the vi% i question represents the rib con- nected with the atlas-center (the true atlas-rib), but since I have ie shown that the axis-rib has not disappeared in the living Crocodilia, Py but is shifted in front of the axis successively, I must abandon be this view. Koken believes that the additional “ rib” in Teleosaurus rep- resents the tubercular part of the atlas-rib. This may be, but it = ` iş not probable. If the atlas and axis of the Parasuchia (Belo- a Stagonolepis) are known, we probably will get more light on -this point. i I give the following results: : | All crocodiles possess ribs of the'atlas and ribs of the axis. In the older crocodiles (Teleosaurus) the axis-rib has a well devel- - ped capitulum and tuberculum, the latter articulating with a well- _ devloped diapophysis.

Lancaster, published in Nos. 11 and 12 of the Naturatisr for 1885, the writer attributes the power which is utilized by the bird, no doubt correctly, to the condensation and expansion of the atmosphere, produced by the relative motion of the bird with respect to the atmosphere. An evaluation, if it were practicable, of the excess of the upward, above the downward, atmospheric pressure upon the bird, when it soars horizontally or remains stationary on fixed wings, would show, no doubt, that such excess is exactly equal to the weight of the bird; and the rear expansion on a vertical section of a bird that remains stationary on fixed wing in a current of aif; ko would be found to be exactly equal to the force exerted by the breeze. No other explanation of the phenomenon is conceivable, and this is substantially the explanation suggested by Mr. Lan- -vertical descent, _. This is obviously a misinterpretation of the phenomena ; for -itis well known that the upward lateral force would arrest the downward motion, so that the cause of the upward motion woul be immediately withdrawn ; and besides, it leads to the absurd con” “clusion that the secondary effect of gravitation, through the com - action. ; Obviously the best the bird can do to sustain his elevation m still air, will be, by suitable position of his wings, to effect a 5#¢ _cession of descents and ascents, thus utilizing, not only the con- -densation produced by his descent, but also the momentum _ acquired by his velocity. | it es pees ge ee Fi EA p aes ha fia eerie fier uke NU aCe = ST SS I L E _ densation and expansion of air, may exceed that of its direct AREN OSS Lemos Pe ee ey a 1886.] Zoology. 295 It follows, therefore, that soaring birds utilize zwo forces, viz., gravity and the motion of the atmosphere, and that without atmos- pheric motion other than that produced by his descent, a soaring bird cannot for an instant maintain, undiminished, his energy of position —/.

On THE Types oF TooTH-sTRUCTURE IN MAMMALIA.—The trifid form of the lower molar of the genus Monachus and of Meso- nyx is in reality repeated in the cusps of the molars of Ungu- lata generally. In Sus the second upper molar cusp' sends a long basal process forward and outward toward the canine cusp and may be said to represent the anterior cuspule of the trifid figure of the plan of cusp itself, while the posterior cuspule is aborted. The bicuspid cusp exhibits a small anterior cuspule which ex- tends directly outward to reach the base of the canine cusp. Both the ridges formed by these cuspules are the first to become worn in mastication. This plan of arrangement is repeated in several extinct genera. among which may be mentioned Phenacodus and Hyracotherium. In Hyracotherium cuspidatum? the cuspule is placed obliquely to the true molar cusp, precisely as in Gymnura, instead of being continuous with the cusp.

The object of the cuspule is to support the cusp, to the base of which it is attached. Indeed, it presents the first attempt to modify the bunodont type of dentition toward the lophodont type. It is consistently main- tained only when the strain of impact is of moderate amount. Should the strain become excessive the lateral border of the tooth : is arched inward, as first pointed out by Ryder.’ In the presence = of these strong arches or flutings the main surfaces of attrition no longer need the basal cusp supports and they disappear. This change is illustrated in Paleosyops and Limnohyus. en a tooth becomes worn and an island of dentine appears at the summit of the cuspule it is often seen to be obliquely -~ placed to the main cusp. This is occasionally seen in Acheno- don and Mastodon and constantly in Hippopotamus. A key isin this way afforded to interpret the islands of the complex tooth of Phacocherus. Care should be taken not to be misled in applying this method of interpretation to intricate types of tooth-structure, such as Polymastodon and its allies, for in these genera there €x- ist true cusps only (cuspules being entirely absent), and the third row of islands (when such exists) being simply a linear row of well-defined characters placed along the border of the tooth. ~ A tooth that has been for a long time subjected to the action of a dilute acid is entirely deprived of its enamel, and permits the super- _ ficies of the dentine to be clearly seen. It is of interest to note that the cusps upon the dentine of a tooth thus prepared, while corresponding in a general way to those on the free enamel surface, E are sufficiently distinct therefrom to afford material for comparisons, i and to suggest relationships of a different character from those determined by the study of the entire tooth. Thus the dentine cusps of the premolars of Sus suggest the form of the correspond- ing teeth in Monachus and of Mesonyx. The cusps of the third molar of Sus are strikingly like the molars of the Insectivora and of lower molars of the genus Bathyopsis.

Gaillou made known the fact that the green coloring of the European oyster (O. edulis), is due to the fact that it feeds upon a diatom, the Navicula ostrearia Gaillou. This has been persistently ignored by the advocates of the copper theory, possibly because of the peculiar blue-green of the gill . lamellz, etc., of the oyster. The Navicula in question contains a blue-green pigment. diffused through its protoplasm. This pig- ment is absorbed by the blood of the oyster from the contents. of its alimentary canal, and collected by certain secretive cells which are limited to the surface of the branchie and the adoral face of the labial tentacles. Arthropoda—J.S. Kingsley contributes to the Quart. Jour. Mic. Science (Oct. 1885), some notes on the embryology of Limulus. He regards Limulus as an arachnid, but states that it takes us back to a time when the distinctions between the Crustacea and Arachnida were far less marked than now. He also describes the outlet in the embryo of the brick-red glands. From an article in the Quart. Jour. Mic. Science, by Professor A. Sedgwick, it appears that there are two species of Peripatus, P. capensis and bal- fourt e latter has eighteen pairs of fully developed legs, and is of smaller size than the better known species. The male organs of Peripatus are a couple of blind tubes, united near their ter- mination. It does not appear that any portion can be extruded, 7 and the spermatophores seem to be deposited upon any part, even : on the head, of the female. Yet the uterus of the female, con- sisting of two tubes closely applied, is altvays full of embryos. Fishes—Dr. J. Beard gives, as the result of a continued study. of the branchial sense organs in the Ichthyopsida (Quart. Jour. Mic. Sci., Nov. 1885), the conclusion that aż present we are acquainted with no invertebrate nervous system which is built upon _ the same plan as that of vertebrates. O 2 Birds=Dr. H - Rhea.

This will be evi- dent if Figs. 9, 10, 11 and 12 are compared with the earliest stages of Isotoma figured by Packard in the memoir just cited. One feature in the development of Anurida which has inter- ested me greatly is the presence of a very rudimentary spring or elater, e/, shown from below in Fig. 4 and from the side in Fig. 3. This appendage, which probably represents a pair of degenerate limbs, is produced from the anterior, inferior part of the fourth abdominal segment, but on the ventral side of the adult no sign of its presence is visible, as may be gathered from an examination of Fig. 1. This organ in Anurida does not arise from the penul- timate segment, as in Isotoma, as stated by Packard, but from the antepenultimate or fourth abdominal segment which is in reality the one from which the elater arises in such genera of Collem- bola, as Lepidocyrtus, Triana, Tomocerus, etc. In the just- hatched larval Anurida, the elater is developed to exactly the same degree as in Triena mirabilis Tullb., according to Brook.’ The inference, therefore, is that the springless genera of Collem- bola are degenerated forms which have descended from others which were provided with well-developed elaters. In fact it 1$ now possible to trace the gradual degeneration of the elater through the genera Achorutes, Xenylla, Trizna and the young of the species under consideration here. Linking this series with those having a more developed elater and tenaculum, and these again with such forms as Campodea and Machilis, we réalize what a remarkable series of differential changes the abdominal appen- dages of the Thysanura and Collembola have undergone, starting probably from the still less modified Symphyla, in which there is no differentiation even between the appendages of the thorax and abdomen. The earliest stages were not considered, as the ova were too on _ Opaque to be studied by transmitted light, and the earliest intima- tion of the formation of the germ is shown in Fig. 8 at gå, the germ- eing viewed in profile transversely or from one end. The 1-band or ventral plate forms a pronounced thickening which = lies on one side of the vitellus, with its longest diameter coim- ciding with the longer diameter of the egg. This germinal band soon becomes widest anteriorly, as shown by the transverse pro- file views of it represented by Figs. 11 and 12. From these ar ~ lateral profile view (Fig. 10) of the same stage, I have con- __ Structed the diagrammatic representation (Fig. 9) of the germ- band as it would be seen by a object, extending over very nearly a semicircumference of the - reflected light, or as an opaque re 1 Journ, Linn, Soc.

In the later profile (Fig. 10) the germ-band shows the appendages of the embryo developed as follows : the antennz az, the mandibles wd, the maxillæ mr, the three pairs of legs, 7, 2 and 3, the collophoral segment, 1, and the following abdominal segments up to vi. In the next stage, when it may be said that the embryo is already beginning to lengthen, as shown in Fig. 7, the ventral plate, with its appendages, is no longer convex when viewed laterally in profile, but becomes strongly concave or bent upon itself, and it then appears as if it had been shortened, the embryonic appendages being also much crowded together at their distal ends, as shown in Figs. 6 and 7, which represent the same stage viewed from in front and in profile. In the course of fur- ther development the embryo increases still more in length, as shown in Fig. 5, when it may be said that the definitive form of the parent animal begins to be obvious. By this time the limbs and antenne have become definitely segmented. During the earlier stages the limbs, antennz, collophore, etc., had the form of mere blunt, paired papilla, or of blunt, clavate, tentacle-like paired outgrowths from the lateral surfaces of the ventral plate or elongated germinal area, e changes which determine the appropriation of the yolk, or whether a dorsal organ is developed which takes part in this or not, as held by Korotneff in the case of Gryllotalpa, are points which have not been made out. This, as well as the manner in which the blastoderm is formed, can only be made out by means_ of sections. ee The eggs, as well as the adult animals, are not, readily wetted with water or even in.dilute alcohol. I have succeeded in har- a dening them by treating them first with weak alcohol and after- X wards placing them in dilute chromic acid or Müller’s fluid. The egg of this species, after the formation of the germinal plate, is invested by an inner covering, 7, and an outer one, a as shown in Figs. 8 and 10. By very careful manipulation under a compressor the outer one may be ruptured, when it will be dis- covered that the inner one is wrinkled in the most singularly symmetrical fashion, as represented in Fig. 8. Whether this sec- ond wrinkled covering is the serous envelope or amnion I am not certain. It may be that it is a cuticular chitinous secretion from the cells of the blastoderm, such as has been found by Kingsley" to invest the embryo of Limulus while yet in the egg. Inside the second egg-envelope, and between it and the ovum proper, ere is a very considerable perivitelline space, 7, developed. __ Imperfect as these notes are, I publish them, first, because the development of this form differs greatly in its external features — from that of Isotoma, described by Packard; secondly, because > the development of this type recapitulates very briefly the devel- !

A committee was appointed consisting of Drs, Sternberg and Smart, of the Army, Raymond, of Brooklyn, Vaughan, of Ann Arbor, Leeds, of New Jersey, Watkins, of New Orleans, ang _ Rohé, of Baltimore, to investigate the efficiency of the various | obtainable germicides and antiseptics in respect to sanitation and preventive medicine. Probably no more competent and conscien- tious workers than are some, if not all of the members of this fectants are antiseptics, but not all antiseptics are disinfectants. The work of the committee was limited to the study of the dis- infecting properties of the substances investigated. . e report consists partly of the descriptions of original experi- ments, and partly of historical essays, embodying the results of the most trustworthy investigators in this field. The general reader would search in vain the mass of bacteria literature to find some definite idea of the comparative value of different disinfec- tants ; but in the work before us the confusion is reduced to 4 | Minimum, because the many different substances investigated are considered from the same standpoint and after the same methods. _ - It means very little when one experimenter declares that chromic acid, for example, is an antiseptic in the proportion 1 : 1000, and another that carbolic acid has the same power when of the stre I: 500; for the more concentrated the strength of the germ-food solution the greater must be the concentration of the antiseptic to =~ be efficient, and a percentage of antiseptic, that would prevent the _ / development of germs for the space of three days, might be liv _ down by bacteria in the course of six. | © — Mercuric chloride as a disinfectant easily stands at the head of substances readily obtainable.

He located this center in the medulla oblongata, confining it indeed to a very limited por- tion of the medulla in the region of the origin of the vagus nerve. Flourens repeated Le Gallois’s experiments and localized the cen- _ ter. toa small spot in the gray matter at the level of the calamus _ Scriptorius which he named the “ncend vital.” Later workers _ demonstrated that the respiratory center of the medulla is bilat- eral. Longitudinal sections along the middle line of the medulla do not prevent the respiratory movements from taking place. No part of physiology seems to have been more generally accept than the existence of this center in the medulla, though its exact | position has always been and is still a matter of controversy. In - 1873 Gierke made a thorough investigation of the subject, his _ method being to make lessons of different portions of the medu as narrowly localized as possible; and after observing the effect of his section to harden the medulla and study the lesion by Saal Sees eadhan ai 1886.] Fhysiology. 305 tory movements. Microscopic study of this region convinced him that the spot whose destruction had.this effect was a bundle of nerve fibers lying outside of the nucleus of the spinal accessory nerve and below the nucleus of the posterior pyramid. This result was of course very unsatisfactory. According to the pres- ent conceptions of physiologists nerve centers must always con- sist of nerve cells, and it is not conceivable that automatic stimuli can arise in nerve fibers. ‘If investigations had rested here this collection of fibers could only be looked upon as the efferent fibers from a center whose location had not yet been determined. Other physiologists have denied the existence of a respiratory center in the medulla, altogether holding that the centers govern- ing the respiratory movements are situated in the spinal cord. While others have described respiratory centers in the floor of the third ventricle, or in the corpora quadrigemina in the gray matter surrounding the aqueduct of Sylvius. Two interesting commu- nications on this subject. have appeared recently in the Central- " blatt f. Med. Wiss., Nos. 27 and 34, 1885. Unfortunately these Investigations have given different results, so that we are still left in doubt as to the location of the medullary center, though it looks as if the problem was very near its final solution. The first com- munication, No. 27, is by Mislawsky. He states that Gierke’s bundles have nothing to do with the respiratory movements. fourth ventricle, Destruction of this centre on both sides com- pletely stops the respiratory movements, while injury to one side attects the respiratory movements of that side alone. The efferent — fibers rom this center to the spinal origin of the nerves of the respiratory muscles Jie‘ outside of Gierke’s bundle. In No. 347 -of the Centralblatt, Gierke replies to Mislawsky’s criticism. He States positively that the group of cells described by Mislaw- — ‘Sky as the respiratory center does not exist; that the locality ‘assigned to it, is occupied entirely by the reticular formation, and it is the scattered cells of this formation which Mislaw- “Sky -has mistaken for a definite nerve center.

INTELLIGENCE OF ANTHROPOID ApEs.—In his excellent work on anthropoid apes, Professor Hartman, the Berlin zodlogist main- tains that anthropoid apes in nature “ develop an intelligence which : sets them high above the other mammals. They do not, how- ; ever, display the keenness of scent and quickness of sight which distinguish some animals of a lower order, such as canine beasts of course to cunning, and looked anxiously about to see if he was _ watched. It was just in these cases when he obstinately pursued a fixed idea, that it was impossible not to recognize a deliberate _ plan and careful calculation. If, for example, he was not allowed to © __. leave the room, or, again, was not allowed to come in, he would, after ; several attempts to get his own way had been baffled, apparently _ Submit to his fate, and lie down near the door in question, W -assumed indifference. But he soon raised his head in order to. ascertain whether fortune was on his side, edging himself gradu-. ally nearer and nearer, and then, looking carefully round, he twisted himself about until he reached the threshold; then he got up, peered cautiously round, and with one bound galloped. | as und _ “es assumed such large dimensions as to have its special we XX.—No. IM. e ' 1886.] Psychology. 307 opposite direction, only altering his course when he believed that he was no longer observed. He then went straight to the room and cupboard, opened it, and made a quick and dexterous snatch at the sugar-box or fruit-basket, sometimes closing the cupboard doors behind him before beginning to enjoy his plunder, or, if he was discovered, he would escape with it, and his whole behavior made it clear that he was conscious of transgressing into forbid- den paths. He took a special, and what might be called a child- ish pleasure in making a noise by beating on hollow articles, and he seldom omitted an opportunity of drumming on casks, dishes or tin trays, whenever he passed by them—a noisy amusement to which he was much addicted during our homeward voyage on board the steam-vessel, in which he was at liberty to roam about. “ Mafuca, for a while, was pleased with the companionship of a pretty sea-cat monkey, but she teased the creature so much that a special refuge was set apart for it, into which she could not en- ter. She was so scared and terrified by a heavy thunder-storm that she seized her sleeping playfellow by the tail and dashed it to the ground. She chased the mice which ran about the cage with deadly fury. She was much afraid of snakes, which is not usually the case with chimpanzees. If she was left alone any time she tried to open the lock of her cage without having the key, and she Once succeeded in doing so. On that occasion she stole the key which was hanging on the wall, hid it in her axilla and crept quietly back to the cage. With the key she easily opened the ock, and she also knew how to use a gimlet. She would draw off her keeper’s boots, scramble up to some place out of reach With them, and throw them at his head when he asked for them. She could wring out wet clothes and blow her nose with a hand- kerchief. When her illness began, she became apathetic, and ooked about with a vacant, unobservant stare. Just before her death, from consumption, she put her arms round Schopf’s neck when he came to visit her, looked at him placidly, kissed him three times, stretched out her hand to him, and died. The last moments of anthropoids have their tragic side.” Dr. Prever’s Criticism or TELEPATHY.—Professor Preyer, of Jena, well known through his researches into hypnotism, the de- opment of the infant mind, etc., does not believe in telepathy, ` vel ng attempts in a twenty-page article to give the readers of the January Rundschau the reasons for his skepticism. His criticisms “ S i 2 large number of female members and participators shows € very outset that a strictly scientific spirit cannot be rc erlying the society’s proceedings.” But since the le sc c Eo -308 we General Notes. [ March, quarters and a library, and since it includes among its active or honorary members such names as Balfour Stewart, Lord Ray- leigh, Professor Bowditch, Mr. Crookes, and Mr. A. R. Wallace, Preyer thinks it worth while to examine their proceedings criti- cally, so as to caution his countrymen against these useless pro- ceedings, and prevent, if possible, the formation of a similar society in Germany. Preyer’s analyses of a number of the 600 reported cases of telepathy are exceedingly ingenious and subtle. Though he concedes that the possibility of thought transference _ cannot be disproved, he makes out a good case that the experi- menters ignored sources of error which vitiate their conclusions. Especially ingenious is his explanation of the countless ways in which the two persons to be examined can communicate with each other, if in the same or adjoining rooms—as by means of different noises made in breathing through the mouth or nose, © movements with the foot, gnashing of the teeth, etc.; remember- ing at the same time that individuals, owing to great nervous sus- ceptibility or to training, are endowed with as abnormal acuteness of the senses as are hypnotized persons. In Liverpool, for exam- ple, two girls were examined who claimed that one could tell what the other ate, if the latter was allowed to put her hand on the former’s shoulder. Aside from the fact that there might have ‘ been a prearranged alphabet of signs through pressure on the shoulder, there was the probability that one of the girls hada 64 ‘very acute sense of smell.

The author, after a very elaborate treatment of the subject, illustrated by numerous figures, closes with some observations upon the origin of labretifery and mask-wearing in America, which apparently cles forth Major Powell’s essay on activital similarities. Rejecting Northern Asia and the Atlantis theory, holding as kaan improbable the theory of similar causes acting to produce similar effects, Mr. Dall concludes that the ‘great congeries of islands, known as Polynesia and Melanesia, offer the most plausible solution of the pro oblem Dr. Matthews has a short paper beautifully illustrated and per- fect of its kind.

J. von Tschudi, who at present employs himself in making digests of ethnologic material previously collected. These papers are partly of an anthropologic, partly of a topographic or linguis- tic import. Among the latter we mention : “ Die geographischen Namen in Peru,” eight pages, in Kettler’s Geographic Magazine; “Remarks on Lopez’s communication on the tribe of the Calcha- qui Indians,” in the Argentine Republic (Zeitsch. f. Ethnologie, 1885), in which v. Tschudi lays stress upon the total disparity of the tribe spoken of with the Kechuas in their language; “ Das ma in seinen Beziehungen zum altperuanischen Volksleben ” (Zeitschr. f. Ethnologie, 1885, pp. 93—109), a very instructive trea- tise, based alike on history and on the author’s own ethnographic and local investigation. The extensive terminology of the Indians to designate all kinds of young, old, spotted, etc., lamas is o peculiar interest to the linguist.—A. S. Gaschet. \ SUPPLEMENT TO THE GRAMMAR OF THE CAKCHIQUEL LANGUAGE. —Dr. Otto Stoll, a physician of Ziirich, Switzerland, who has lived five years among the Indians of Guatemala, has written Some important “Supplementary remarks to the grammar of the Cakchiquel language, edited by Dr. D. G. Brinton.” This article was read before the American Philosophical Society of Philadel- phia, February 6, 1885, and printed in its Proceedings. Stoll’s X remarks form a series of rectifications and criticisms upon the antiquated method followed by the ancient ecclesiastics in writing up grammars of the American languages, and the frequent misappli- Cations in their terminology. As to the name Cozumelguapan, Stoll thinks it is of Nahuatl origin, and quotes the etymology of ee uschmann, “ Near the rainbow water.” He may rest assured, that only the local ending -pa, -pan is Nahuatl, and that cozumel is a Maya word, signifying szallow.—A.

METHODS oF INJECTING ANNELIDs (Maurice Jaquet).?—For an- nelids with dark tissues like Hirudo, a light-colored (white or yellow) injection-mass should be employed, while for transparent animals dark colors are preferable. Chrome yellow serves asa good coloring substance. It is easily obtained by mixing solu- tions of bichromate of potassium and acetate of lead. A copious. yellow precipitate is formed, which should be washed on the filter, and then exposed to the air until nearly dry. The pigment, after being reduced to a pulp-like state, is added to an ordinary aque- ous solution of gelatine; and the mass is then filtered warm through linen. If the injection-mass is to be blue, then the gela- tine may be dissolved directly in liquid Prussian blue, and the mass filtered througn the paper: As a rule, annelids must be killed before they can be injected. Chloroform and alcohol are the means commonly employed in killing for the purpose of injection; fresh water may also be used for some marine species. A leech, for example, is placed in should be allowed to remain in the water from one to two days before attempting to inject it. The simplest and most convenient form of syringe consists of a glass tube drawn to a fine point at one extremity, and furnished at the other with a rubber tube. Preparatory to injecting, the glass should be plunged in warm water for a few moments; then, after expelling the water, it may be filled with the injection-mass by sucking the air from the rubber tube. If the injection-mass is _ turned into the large end of the glass, it may happen that gran- ules are introduced which are large enough to obstruct the nar- row passage of the small end. After inserting the cannular end _ in the vessel, clasp both with the forceps, and then force the in- jecting fluid, by aspiration through the rubber tube, which is held in the mouth. When the operation is completed, place the animal in cold water, in order to stiffen the injected mass. Aw InjEcTION-Mass TO BE USED Corp.—3 l PS B ( i solution) I part.

This fluid may be kept for months, and is readily thinned to any desired consistency by the addition of water. Before using, it should be tested with alcohol. A small quantity is placed in a test-tube, and then a little alcohol added. he fluid is at once changed to a solid mass of double the origi- nal volume, and this mass is insoluble in water. Thus the whole process consists in this: that borax and gum arabic form together an insoluble colloid mass; by pressure through linen, with water added, the mass passes into a fluid con- dition which can be diluted to any extent with water ; after injec- tion and immersion of the preparation in alcohol, it again assumes a colloid condition in which it is insoluble in water. The mass thus prepared may be colored with finely powdered carmine, or with other coloring substances ; only cobalt and cad- » mium are to be avoided. _ This mass is especially recommended for macroscopic injec- tions, and for the injection of lymphatic spaces. The injected vessels do not become hard, and the mass does not escape from ruptured points. During dissection the preparation should be covered with alcohol. n case it becomes desirable to dissolve the injected mass from any part of the vessels, this can be accomplished by dropping di- lute acetic acid upon it. The preparation can be rendered transparent by first washing with water, and then soaking in glycerine. Treatment with alco- hol again restores the opacity of the preparation.

Dear Sir:—In the February number of the NATURALIST you say with regard to Professor Marsh’s Zinoceras stenops, formerly referred by you to a new genus Tetheopsis: “I now learn on good authority that the symphyseal region in the specimen in question is entirely constructed of plaster of Paris.” As I am the one from whom you derived this information, I feel bound, as a matter of simple justice, to correct the above statement, for having just reéxamined the specimen with great care, I find that was in error in a very important respect. It is true that the left half of the symphyseal region (the only part visible when I first saw the specimen) is restored in plaster, but the right half is in- tact, and the restoration and drawing were made from that, a per- fectly legitimate proceeding. So much I can positively state of my : own knowledge, and I am also informed that the restoration was a made after the time when you saw the specimen and after Profes- = sor Marsh’s figure was published. Hoping that you will give . this correction a conspicuous place, I remain, a ery respectfully yours, W. B.

In 1842, he went to Barbadoes and afterward to Jamaica, where he became acquainted with Professor C. B.

But here comes a nice distinc- tion between the condemnable and the commendable, between romancing in science and the scientific imagination. Goethe’s guesses were neither blunders nor vagaries. His theory of the genesis of the flower, of the vertebrate origin of the skull, and his forecast of the doctrine of descent, were all marvelous births, but legitimately begotten, the offspring of pure scientific imagina- tion. As in advance of the thought then in vogue, they seemed prematurely brought into the light, and for a time were nurslings of unpromising vitality. ‘But a truth thus evolved finds no similitude in the sparx struck out by flint and steel. Nor is such truth premature, as to its ratiocination, as would appear could we but time its gestation. I think it is always the outcome of “ unconscious cerebration.” The mind of the seer has been deeply thinking on generic lines. As first expressed such a truth may be ore-like—rich, but crude— and it may have to wait for the facts which shall serve as faggots for the crucible. Having in the article “ Coati-Mondi and its Cousins,” with per- haps seeming insufficient warrant, asserted for Nasua a quadru- manous kinship, now that the faggots have been got in plenty, why not smelt the ore? Or, dropping metaphors, let us $° in direct quest of Nasua’s ancestry, even its biogenesis, upon rea- soning lines. j _ In tracing the pedigree of some regal line, perhaps we should reach a very ancient Norman stirp.

These all pointed to a physical correspondence, and looked directly to ancestral inheritance. 3. Ithink it was in 1873, the year after the appearance of my article, that an interesting anatomical discovery was announced i by the great academician, the successor of Cuvier, Henri Milne- 3 Edwards. He had dissected a Nasua and had discovered in the E . limb bones of this animal structural alliances to the lemurs, or Nate lowest monkeys. Here was, indeed, a pleasant and important A confirmatory fact. 4 nt But to round up the proof, one more class of evidence is i needed, the testimony of palæontology. In behalf of the extinct ‘ animals will the fossils bear witness in this matter?. The writer ~ y Was instructor in the natural sciences in the grammar school or is X preparatory department’ of Rutgers College, when he received r from its author a pamphlet “On the principal types of the orders of Mammalia Educabilia,” by Professor E. D. Cope; read before ` the American Philosophical Society, April 18, 1873. My eyes — | ! caught a foot-note to one of the pages, thus: “ Dr. Lockwood, of Rutgers College, in a recent number of the Popular Science _ Monthly, expressed serious suspicions of the quadrumanous rela- __ Honships of the Coati, little thinking at the time that the speci- _ Mens to confirm his view were at that moment in the hands of 3 - _ this world’s life-history had consisted of animals of a very low ? meee on the mammalian lines.

[April, — ancestors of those animals which are included in the zoological term Educabilia, whose cerebral physiology has been already explained. As notable genera of those days I may mention the pseudo-bear—Notharctus of Leidy, and the cut-tooth beast— Tomitherium of Cope. Others there were by Marsh, but their descriptions are not in my reach. Leidy’s species, Notharctus tenebrosus, described from very limited material, was a little ani- mal about two-thirds the size of a raccoon. Cope’s species, Tomitherium rostratum, founded on a much larger amount of material, was an animal probably about the size of Cebus capu- cinus, the prehensile-tailed monkey so common in shows. Upon technical considerations both these animals, albeit their strange and high-sounding scientific names, were low-grade monkeys. They were quadrumanous animals but of a synthetic, that is, ` comprehensive type. The femur of Tomitherium was so long as to indicate that the knee was entirely free from the body, as it is in the whole monkey tribe of to-day, but never in any of the r carnivores. The round head of the radius indicates a complete ; power of supination of the fore feet; that is, the ability to lift the hand, so to speak, forward and to turn the palm upward, a faculty of limb peculiar to monkeys and man, while the distal or lower end of the same bone resembles closely that of Semnopithecus, 4 high-grade old-world monkey. “ We have then,” continues Cope, whom we are epitomizing, “an animal with a long thigh free from the body, a foot capable of complete pronation and supination, and a form of lower jaw and teeth quite similar to that of the lower monkeys.” ~ And in this connection what about our Coati ? Says the profes- sor: “ A comparison with Nasua reveals no distant affinity. the fore limb presented in Tomitherium a great similarity to that _ Nasua.” And in both genera are some striking similarities in the cutting teeth. “The first impression derived from the appearance of the lower jaw, and the dentition, and from the humerus, is that Tomitherium is an ally of Coati, the humerus being almost a fat- __, stmile”” And is it not a striking coincidence that Professor _ Leidy’s first impression of Notharctus was of a resemblance x ~ Procyon, the raccoon, which,as we have shown, is generic with - Nasua. It is evident then that Tomitherium and Nasua show some _ alliances in structure which look to a common origin or biogene sis, but it is a descent on different lines. From his study Ae 1886:] The Ancestry of Nasua. 325 immense amount of fossil relics from the same geological forma- tion which yielded Tomitherium, Professor Cope has erected the order Taxeopoda, which includes these fossil lemurine forms. This order occupies the earliest section of the line of the Pri- mates. First in these fossil forms come the Lemuroids at the base of the Primate lineage. After these extinct forms appear the true Lemuroidea, that is, the present or living Lemurs, fol- lowed by the monkey proper, and these by the anthropoid apes. Now, among the lemurine forms,and fairly started on the quadru- l manal line of descent from the typical lemurine order Taxeopoda, occurs Phenacodus, after which Tomitherium appears somewhat farther advanced on this Primate line. Now, on an off-line or branch from the lemurine Taxeopoda, Starts the flesh-eating line; first the Creodonta, the “ slaughter- teeth,” then the Carnivora proper, with the present living forms. Cercoleptes connects Nasua to the extinct Creodonta, and through these back to the lemurine order Taxeopoda, their 3 ancestral stock. ‘ So we have at last found the Nasuan lineage and ancestry in the Eocene times. Phenacodus was an animal of a synthetic struc- ture, a comprehensive type, from which flowed several ordinal streams of life. In such a composite form, or structural make-up, ` can we not surmise the creative possibilities and purposes of the > Divine Mind ? It is an interesting fact that in a direct line one of Nasua’s ances- tors still exists in the same forests of South America. The kin- kajou, Cercoleptes caudivolvulus, reduced to one species. When tamed it is an interesting little animal with amiable ways and > monkey traits. The tail is prehensile in that it curls around an : object, which with plantigrade feet give it in Germany the name. curling-bear.

So then, Sy kinkajou and Coati-Mondi come honestly by their monkey tricks, — having a clear title by heritage. | pe - Without turning homilist let me close by citing Ruskin and oF One of the great ancients: “The greatest thing a human soul ‘ver does in this world is to see something.” The Hebrew bard both sang and prayed : “ Open thou mine eyes, that I may behold : glorious things out of thy law!’ And this biogenesis of Coati- : Mondi, is it not one of the wonderful things—an outcome of Divine law? ee aso The Mechanics of Soaring. [April, THE MECHANICS OF SOARING. BY I. LANCASTER. ; k was foreseen that the paper on the soaring birds in the November and December numbers of the NATURALIST of last year would provoke adverse criticism where it dealt with expla- nations of the movements of those creatures. The recognized laws of the mechanical forces being formulated from data derived from systems of which the earth is a part, makes it extremely difficult to deal with phenomena which are independent of that body, while still existing in its atmosphere. 3 here arises at every step taken to elucidate the matter, a a seeming conflict with accepted laws, and however faultless the ce reasoning, it is discredited because of that apparent antagonism. | The word “soaring” is also a bad one to name the mechanical actions involved, as it implies a bird. No better, however, is at hand, and it denotes the method employed. by the bird and not necessarily the creature itself, as it is here used. While prosecuting the subject experiments of various kinds were conducted to dispel the obscurity which enveloped it, as careful observations had shown that it was completely different from any other kind of bird flight. Of almost half a hundred _ theories framed on postulates of bird or air, which were not true, one at length was found to be consistent with the facts. I sud- denly found myself in the ludicrous predicament of industriously attempting to prove an axiom. My experiments became value- Jess. Time and means had been wasted. There already existed _ recognized data to make the whole case self-evident. ae It is now more than five years since the discovery of the — _ mechanical activities herewith detailed. During that time the -matter has been made a study in all its bearings, so that mistaken mechanical world as worthy of serious attention. : ~ | Tethnically, the material system of soaring is a flat surface, atf, _ and a force. The gravitating force is not essential to it. Any _ force, a push with the hand, horse-power, steam-power of any other will fill the conditions. Neither is atmospheric ait essential. The air must have the quality of great elasticity and offer con- siderable resistance to a moving body which compresses or drives -it out of the way, and very little to the passage of a smooth, flat surface like a sheet of tin, edgeways in it. The force is then oo ee be avoided, and it is herewith presented to the o 1886. ] The Mechanics of Soaring. 327 applied to the body in such a way as to move it at right angles to the direction in which the force acts. This translation of the body is “soaring.” It rests on two universally recognized laws. The most important is the conservation of energy, of which it is the most beautiful illustration to be found in mechanics. The other is the reaction in all directions of fluids under the action of mechanical forces. _ The body must be so constructed as to have at least two direc- tions of motion which are unequally resisted by the air. , The case will be first presented as operating in space devoid of gravitation, where the body will have no weight, and . afterwards the system will be introduced. into the earth’s atmos- phere. Implications arising from the action of gravity, and the constant tendency to introduce the earth into the soaring system, will be avoided Í Suppose the body to be an oblong flat surface, such as a sheet of tin 12 x 72 inches, and that æ 4 is its transverse section, and that the force moves from c towards d, at right angles to the sides * of the surface. é i č Se Ee P eee A, m S x 5 z : n ; d eo Surface at right angles to the direc- Surface inclined to the direction of tion of the force. the force. 2 | 328 The Mechanics of Soaring. [ April, “That the value of the force is twelve pounds moving the surface on the air with uniform velocity, which we will suppose to be five feet per second. Under these conditions it is obvious that all the force is employed in condensing and otherwise disturbing air, so _ that it is doing work on the air at the rate of twelve pounds each second. It is also obvious that while uniform velocity occurs there is a moving equilibrium between the surface acted on by the force and the reacting air, and that any additional force, however small, applied to the surface at any angle to its own plane would disturb this balance, and either accelerate or retard its velocity. If, however, the additional force be applied in its plane, lateral motion would occur without changing the equilibrium. In the lateral motion no air is disturbed, nor driven out of the way, nor condensed, excepting what is caused by smooth skin, or surface friction, and this is so very small as to elude all my attempts to find its value. One pound applied in the plane of the surface would doubtless drive it at the rate of 1000 feet per second. We will an suppose, however, that one pound will drive it from 4 towards @ at the rate of thirty feet per second. As it is moving towards d | at the rate of five feet per second, it will pass neither towards d „nor a, but on the diagonal å e, the resulting path, the parallelo- -gram being thirty feet long and five feet wide. _ Note the character of the equilibrium between the surface and air.

So far all is evident, but the surface would not fill the condi- tions of soaring. Its motion is not at right angles to the force, but inclined thereto, and to accomplish the desired result its path must be perpendicular to the force. If we now tilt the surface on one of its long edges, 4, say for two inches, or one in six, it would no longer follow the direction of the force, but slant sideways towards this edge. Following the law of the composition of forces, one-sixth of the force, or two pounds, will now drive the surface sideways, and there being nothing but trifling skin friction to oppose it, it will obey the im- pulse. But if we apply a force of two pounds to the edge to . balance this thrust, equilibrium will once more occur and the sur- : face will move in the path of the force. Experimentally, far less than two pounds is required for this rest, as a considerable incline is reached before the sideways thrust is developed, the confused air currents under the surface obscuring the movement. Note that this abutting force is of the nature of pressure. It is a static feature devoid of motion. It is a rest for the tilted sur- face to lean against. It cannot be denied that we now have a case of equilibrium once more. With the two-pound rest a perfect balance results and the : surface moves in the path of the force. All the force is disturbing i air, while the surface moves with uniform velocity. Af that speed it is unable to offer the least resistance to any further force which may be opposed to it. At this point the answer to a single ques- tion will be decisive. If it be in the affirmative the position is Secure; if in the negative, my explanation of soaring is wrong, _ z _ the birds are still in the air waiting solution. oo _ The question is this; Will the tilted surface, supplied with the rest of two pounds and moving with uniform velocity, obey the ae . impulse of an external force, applied in its own plane, with equal facility in any direction? gee It certainly is evident that the only resistance to such a force — _ arises from skin friction in whatever way the motion is made. — If ou there be any other from whence comes it? It cannot come from: the original force, for this is fully employed. It cannot come from the two-pound rest, as this is already balanced by the side= A of the reacting air. This does not vn pih the PA aE ago. ‘The Mechanics of Soaring. [April, velocity in the plane of the surface. It is two pounds at all velocities; motion in the plane of the surface does not change the | value of the condensations, but only their character. It makes i them thinner but wider, the total of twelve pounds being constant ~ atall velocities; so that the two-pound abutment can only vary with the inclination of the surface to the direction of the force. It is obvious that a force applied to the surface in the direction of its length, will move it either way indifferently. It can be seen at once that the two-pound rest will not resist such a force at any velocity whatever in these directions. Leaving unnoticed any oblique motion neither longitudinal nor transverse, the important point is, will a given force, say of one pound, move the surface towards a, with the same velocity as towards 0 ? ee It is possible that when the lateral motion is set up there might be developed in the air disturbances, differences which woul require an increase or diminution of velocity towards 4, to. bal- ance the twelve pounds, and that these differences would be -.. greater or less towards 6 than a, But this would in no way affect a the lateral motion; Acceleration or retardation would go on until equilibrium again occurred, so that it would bea balanced surface which is moved. The vital point is: Does or can the twelve pounds in any way resist the lateral motion either towards : aorġ?

While the lateral motion is going on at the rate of thirty feet per second, twelve pounds per second of air disturbance “is flowing past the edge å, while but three pounds is required to give the lateral thrust and furnish the two-pound rest. If this edge be rounded upwards along its sev enty-two inches of length to serve as a base for the expanding air to act against, it will give the needed three pounds and still leave nine pounds to go to waste by falling to the tension of the sur- rounding air. With this substitution the soaring action is com- plete. The force is now translating the body at right angles to its own direction: It will be noted that a velocity towards. æ greater than thirty feet per second will cause the surface to move contrary to the direction of the force faster than with it. Also, if a greater inclination be supposed, the abutting force would be greater, and the above contrary motion augmented. A limit would soon be reached in this direction; however. At an incline of one to four the rest would be three pounds, at one to three, four pounds, which latter would pass the limit of soaring, as it would require a rear expansion of five pounds to effect lateral motion, a utilization of five-twelfths of the entire force, which would surpass the ability of the system. A single further peculiarity is to be noted. Suppose the indefi- nite body of air belonging to this system to be in motion, either with, or against, or at any angle whatever to the direction of the © force. The action of the parts of the system would remain unaffected by such motion. It is universally recognized that the Ț translation of a system as a whole has no effect on the AE = tion of its parts. tag Let us now suppose the motion of the body of air containing the system be towards the earth’s atmosphere in a direction tan- _ gential to its surface, at the rate of one hundred miles per hour; until the air of the system and the atmosphere became identical, f we would have a bird soaring in wind of that velocity, and this z air so far as the soaring system is concerned. -In the earth’s atmosphere, surface and air will remain the bird. It is an inert body translated at right angles to the gravi- tating force, or horizontally, and solely by the action of that force. It has constant motion in the direction of gravity but does not lose its energy of position by getting nearer the earth. It resem- bles zx this respect a clock moved by a weight, and placed on the platform of an elevator which slowly ascends, While the clock weight is a falling body having motion in the direction of gravity, it still does not lose its energy of position by getting nearer the _' earth, because of another motion in which it is elevated. The surface, under the action of this force as above condi- tioned, is a splendid atmospheric highway maker. It lays down an endless cushion of air on which it travels with incredible speed. It is paralleled by nothing in nature. It is gravity in the role of a continuous motive power. It obeys implicitly the laws. of mechanics in every paroma and gives man complete domin- ion of the air. When the attention is directed to soaring in the earth’s atmos- phere, as exhibited by the birds, two delusions must be industri- ously guarded against. One is that wind is concerned in the phenomenon. The other is that the horizontal motion of flight is the result of a single impulse acting in one direction. _. When it is seen that motion is derived from gravitating force exhibited by the quiescent bird in all cases, and that its level flight is a compound result of two motions, one vertically down- wards, and one slanting upwards in the plane of the wing sur- faces, both simultaneously occurring, the subject assumes a more explicable form. - * Then when it is seen that no en is lifted in the upward ae slant, | this action bearing no resemblance to a ball rolled up an 2 -inclined plane, the case will be in a fair way to be completely _ comprehended.

H. PERKINS, II—NoTcHED AND GROOVED AXES. N all our collections we find a few axes which are notched or grooved across the narrow sides. They are not common in any portion of Vermont, nor, if we may judge from what has been published by various writers, do they appear to be abundant anywhere in the United States. As was noticed in the preceding article we are able to arrange Our specimens in such a manner that there is a very complete series from the simplest celt, through the notched ax, to the fully grooved ax, and it seems quite probable that the notched ax was the second step in the development of the ax from the simply edged pebble. The form of the notched ax is more s that of the common celt than is that of the grooved 5 ax. In fact some of the notched axes are nothing else than celts notched at the sides, and they are never so large and heavy as are Many of the grooved axes. A type of these axes is shown in Fig. 1, which represents a common form, about one- half the natural size. . Asarule these axes are not more than four or five inches long and two or three Wide. They are usually well shaped, neither rude nor clumsy, and the surface is smooth 9r perhaps polished. The form of some is mh as to eee the adze, and it seems dertaken, was in common use among the prehistoric tribes as it _much ‘of the use of such a tool in their accounts of these people. » dark porphyry and is polished over the whole surface, and is, aS ind = It is four and a quarter inches long and two inches in greatest width. In Fig. 2 we have quite another form of ax, and one whics _ isnot common. It is about four inches long and two and a h inches wide.

I have seen > no > specimen of the notched ax which, like some of the celts, was near the middle as if the maker had thought of notching them _ that a handle might be more firmly attached, and these are al notched axes, although the notch is so very slight that I have = thought best to include e these specimens in the present article.

[April, performing many of the labors which we know to have been un- has been for a long time among modern savages, and yet I do not remember that the early writers to whom we always turn for information respecting the customs of our predecessors, say very It is not impossible that some of the implements which we call celts may have done duty as spades, and that some of the ruder “notched axes” may have been, not axes, but hoes. The notches or grooves are always much wider than deep, although the depth varies very greatly in different specimens, but I have never seen it as'great as in the grooves of some of the larger grooved axes. The notches are usually about a third of the length below the blunt end of the ax, though in a few cases they are near the middle, as in Fig. 2. These axes group themselves naturally into two classes—those in which the width greatly exceeds the thickness and in which the surfaces are nearly or quite flat, and those in which the breadth and thickness are more nearly equal and in which the surfaces are often convex. Some specimens have one surface quite flat and the opposite convex, just ` as is often the case in the celts, and it is pos- sible that these were used as. skin-dressers OF HRD: and without a handle, the notches rving as convenient places for the fingers as the hand grasped ibe tool. -The specimen shown in Fig. 1 is of eed are most of these implements, made with care and skill. ed at both ends, but one or two of the latter are drawn in os FA Specimens, and therefore less clumsy and heavy, even W 1886.] The Stone Ax in Vermont. ; 335 With very few exceptions the grooved axes found in Vermont are larger than those we have called notched axes. They are not at all abundant in any part of the State, and in the northern counties they are very rare. It is quite remarkable that in some localities where celts and other implements are especially common, grooved axes have been very seldom found, if at all. As compared with the Southern or Western grooved axes, our Vermont specimens present differences which are sufficiently noticeable when one looks over series of each, but which can not readily be made apparent in words. Our axes are, in size, intermediate, none of them being so small as the little “ toy ” axes found in other local- ities, nor are any so large as many that have been found. Neither do we find axes grooved only on three sides, but in all our speci- mens the groove extends entirely around the ax. In the collec- _ tion of the University of Vermont there is one specimen, which is doubtfully of Vermont origin, in which the groove ig found only on three sides, but in all the rest the groove is completed around the specimen. This is somewhat remarkable, because, according to Dr. Abbott (Primitive Industry, p. 8): “ Possibly two-thirds of the stone axes found in New Jersey have the groove extend- ing along the sides and across one margin ;” and the same author speaks of “ one-half probably of the axes found in Connecticut and northward having the groove entirely encircling the stone,” and by inference the other half were not so. Our axes usually — have the groove a little above the middle and parallel with the edge. It is never very near the blunt end, as in some of the Western Specimens, nor is it ever bordered by a raised lip. Our average specimens are from five to seven inches long and about | two-thirds as wide, and weigh two or three pounds, but occa- Sionally they are larger, as is the specimen shown in Fig. 5, which | 18 one of the largest axes I have seen from this region. Some of Our grooved axes were evidently made from cobble stones, and in Some of these the upper end is left very much in its original con- dition with its water-worn surface unwrought.

In general form the Vermont axes are Noticeably wider, shorter and thinner than the typical West: a P 336 The Stone Ax in Vermont. [ April, of the same length. The long, slender axes found in some of 4 the Western localities do not occur in the Champlain valley. Our grooved axes are not often very rude but, though seldom polished, the surface is generally well picked and smoothed. The edge is, naturally, always polished, but the groove is not in any specimen so completely smoothed that the pits and striæ made by the instruments used in excavating it are obliterated, and in most cases there is little attempt at polishing it. Even when the rest of the surface is smoothed, the groove is not. This is unlike what is common among stone axes from other places, for in these we very often find the groove finely polished. In Fig. 3 we have represented a specimen of singular form, and in some respects unique. The material of which this ax is made, instead of being of trap or quartzite, or some such hard, compact stone, is quite peculiar in that it is of a red sandrock common along Lake Champlain, and which is not a very suitable material for an ax. As shown in the figure this specimen appears more rude and ill-fin- ished than it was originally, for, either from the effects of weathering or har usage, the smooth surface which evi- ES dently existed at first, has been flaked Seas off in many places; giving a rude appear oe ance. 3 _ This is one of the larger of our axes, the length being eight inches, width across the head four and a half inches, while the gen- eral width below the groove is four inches. The special peculiarity : of this ax is found in the obliquity of the edge, which is not very _ well shown in the figure. That portion of the ax below the gr oove - is not worked to the same plane as that above, but is as if twi i ` spirally so that a line drawn parallel to the edge would cross at 4 on large angle a similar line drawn across the head or parallel with __the groove. Nor is this an isolated example.

So marked is this twist that it would seem impossible to strike a fair blow with such an ax if it was attached to a long handle, and this difficulty raises the question whether some of these large grooved axes may not have been hand axes, not many of them, perhaps, but a few. The head of the Springfield ax is rounded carefully, and indeed the whole ax is very well made, and when held in the hand with the ends of the fingers in the groove, it seems most admirably adapted for use in this way. I am aware that the groove in itself suggests a handle of some (eed Je el i ra aD sg sjua ath? o T oa Ne YA ee fat Ets IE, A >” an ig Atay sh Ca iy pom pee Were het cn t fs 3 7 2h edt ie ee Fic. 4.

The form cannot be regarded as accidental, I think; the specimens are too carefully and thoroughly made to allow place for such a supposition. ae The general character of our Vermont grooved axes is very — well shown by Figs. 4 and 5, which represent the two classes — _— often found.

Scarcely any VOL, XX.—No, ty, ae . oe 338 = The Stone Ax in Vermont. [ April, two specimens are alike, but most of them resemble more or less closely one or the other of the forms here figured. The specimen shown (very much reduced in size) in Fig. 4 is a very well made and finished ax, worked out of a syenite cobble-stone, and the upper end apparently still retains the general form of the pebble. It is of average size, being five inches long and three and a half inches wide just below the groove. This specimen illustrates the short and wide form, while the less common and longer form is seen in Fig. 5. This ax is one of the largest specimens, and most, if not all, of this form are large. Some of them are less rude than that figured, which shows the effects of hard usage,” though it probably was very well finished at first. It is made ofa dark gray grit or hard sandrock, much like that used for making the harder varieties of grindstones. The flat surfaces are rubbed quite smooth, although somewhat pitted. The groove is only mod- erately deep, but is unusually wide, and is smooth as if worn by long usage, and as the figure shows, it runs obliquely. Both sides are flat, one somewhat more so than the other, and the edge is formed by beveling the surface, mainly from one side, This ax, and the same is true of all of this form, was evidently worked out of a mass taken from a ledge. Not only does the smoothness of the groove show that this implement has been much used, but the edge is chipped and broken somewhat, and the head very consid- erably battered as if it had done hard duty asa maul. It has been thought by some that these large axes were, some of them at least, used to break holes in the ice in winter for fishing or to get water, and this specimen may have served for some such work. Very few axes so large as this have been found in this State. The figure is somewhat more than one-third natural size. ` The length is a little over nine inches, and the width above the groove nearly five and a half inches, while just below the groove it is five inches. The specimen weighs four pounds, which is much less than that of some of the Southern specimens. The inequality of the two flat sides, which is sufficient to be quite noticeable in this specimen, is sti!l more marked in some others, and, as in the celts and other forms of the ax, this flattest side is always ‘smoother, sometimes very much so, than the opposite side, a fact for which it does not seem easy to account. Ina skin-dresser OF hand ax it is quite natural that the side which, from accident ; _ Or intention, was most nearly flat should be held down upon the 1886.] The Stone Ax in Vermont. 339 skin or whatever the surface that was being worked, and thus be- come smooth and flat even if not made so at first, but how any- thing of this sort could take place in a large, hafted ax we are unable to guess, unless it was used as an adze, and this is possi- ble. The oblique direction of the groove seen in this specimen is worthy of notice, since it does not appear to be common in New England specimens. Dr. Abbott (Primitive Industry, p. 8) Says that in the valley of the Susquehanna river in Pennsylvania the majority of grooved axes have the groove oblique with refer- ence to the edge, but that this feature is rarely met with in New Jersey and “ probably does not occur in New England. There is no example in the large series of New England axes in the mu- seum at Cambridge.” Several of our Vermont axes, all I believe from the northern part of the State, have oblique grooves. I do not think that archzologists have given the grooved ax sufficient credit for utility as a cutting implement. They seem for the most part to be of the opinion that at best these axes could be used only to cut into the bark and bruise the wood so that a fire kindled about a tree so prepared should have greater effect. This may very probably have been a common, perhaps the common, method, and yet the accounts given us by the early explorers of America seem to me to prove that trees were cut, and cut so that they came down, with stone axes. We must always be on our guard against rendering judgment as to the usefulness of a stone implement if we have no other basis for our decision than the results accomplished by it in our unskilled hands, We all know that stone implements that would be wholly useless in civilized hands are yet of very great efficiency in the hands of Savages who have learned how to use them. Many of Our stone axes do indeed seem quite unfitted for use as cutting are tools, and they may be so, but all are not; some are made from — very hard stone and have a smooth, regular edge which, although © it may not be comparable to that of a modern steel ax, is yet able to cut soft green wood if not that which is harder.

April, the stone axes as used to fell trees, and some of these were “ gros arbres,” and the account shows that the cutting must have been j done with somewhat of expedition. His party had iron axes as well as stone, but our author does not compare the two, but calls them all “meschantes.” In describing the customary method of camping when enemies were supposed to be near, he tells us that as soon as the Indians had chosen the place for a camp, they im- t ‘mediately began to cut down trees to make a barricade, and he 4 says that they know so well how to do this that in less than two hours they have so strong a defence that five hundred of their enemies would not be able to break into it without great diffi- culty and loss of life. Then in another passage he speaks of the Iroquois cutting down trees for a similar purpose. Nowhere does he speak of fire as an aid in the process. Indeed in the first case where he tells us of so strong a barricade, he says that they make no fire lest the smoke reveal their presence to their enemies. From these and similar accounts it seems quite probable, to say the least, that stone axes were used as axes for cutting timber, = ` and with not altogether unsatisfactory results. 3 205 a GROSSE’S CLASSIFICATION AND STRUCTURE OF aes _ THE BIRD-LICE OR MALLOPHAGA.' Bt | ABSTRACT BY PROFESSOR G. MACLOSKIE. HE Mallophaga, or bird-lice, are wingless insects with incom- plete metamorphosis, mandibulate mouth-parts, two or three- _ segmented thorax, eight to ten abdominal somites. They live on mammals and birds, feeding on their scales, hairs and feathers. The genera which are found on mammals never occur on birds, lice with haustellate and others with mandibulate mouth -parts. Nitsch (1842) carefully examined them, and Von Giebel (1874) oo on his ‘work. Nitsch divides them into two chief groups, Philopteride and er Liotheidæ; the Philopteridæ have filamentous antennæ and no > palps; the Liotheidæ have clavate four-jointed antennæ and palps. - l Beitrage zur Kenntniss der Mallophaga, von Dr. Franz Grosse in Strassburg- (7885). : and vice versa.

The Liotheide have likewise two families: (1) Gyropus, the only genus, having one-clawed feet; and (2) Liotheide, strict, with two-clawed feet. Trichodectes and Gyropus occur only on mammals, the other genera only on birds, and are classified according to the presence or absence of appendages on the head (trabeculz) and their mo- tility, to the sexual differentiation of antennz, their attitude, the form of the head, the consistency of the thoracal somites and the form of the last abdominal somites. ; PHILOPTERIDÆ, strictè. 1.

The hinder limit of the clypeus shows on each side a notch, about a third from the front of the head; two dark spots are seen on each side of the head, the larger one near the notch, the other behind it and outwards. The antenne lie concealed in a lateral cavity of the under side of the head (as in Læmo- bothrium, Fig. 1 aż). Two eyes, whose pigment is 1.\—Ventral view of head of Lemo.

In all Liotheidæ it is similarly formed (Fig. 1 ZÆ), being a thin transverse arched swelling, with chitinous margins bearing small bristles. The labrum of the Philopteridæ has a broad disk-like basis fixed on the under side of the head, and is divided by some transverse furrows (Figs. 2, 3,5%).

Nitsch figures them in i Trinotum conspurcatum, but this can scarcely be correct, for he places the four-jointed papillz on the blade near its anterior bor- der. In Tetrophthalmus the palps belong not to the first but to the second maxilla. The same is true of Menopon pallidum, Col- _ pocephalum zebra, a Lemobothrium from Gypogeranus serpenta- rius, and a Trinotum from the swift, and probably is the case with all the genera and species. f Second maxille (unterlippe)—These are flat, fused, bounding E the mouth posteriorly. They consist, in Liotheidæ, of two parts The basal part (mentum, mt) represents the coalesc- ing stipites and squamz St of normal first maxille, and bears the four-jointed labial palps. The upper part is the ligula or glossa (g) corresponding to the inner blade [lacinia]. Lat- erally on the ligula are the paraglosse (jf), corre- sponding to the outer blade [galea].

The paraglosse of Philopteridz, as in the Liotheide, are like tactile-organs, remarkably long in species of Goniodes. In all Liotheidz the intima of the ventral end of the oral cav- ity forms a fold-like duplicature as in Philopteridz (hypopharynx, Fig. 2 hy). In Lemobothrium and Tetrophthalmus this extends forward over the labjum, and its lateral borders are strongly bent upwards (Figs. 1, 8. /y). For the study of the head Grosse made transverse and sagittal sections of specimens fresh from molting and hardened in chro- mic or picric acid.. From absolute alcohol they were placed in chloroform and after two hours embedded in paraffine, being kept _ for a time in melted paraffine under the air-pump. The sections were attached to the slide by means of albumen or. oil of cloves, Stained by alcoholic carmine-solution, treated with acidulated ' alcohol so as to show the nuclei, and then enclosed in Canada balsam. Thorax.—In the genera Trinotum, Colpocephalum and Tetroph- thalmus the three thoracic somites are present, especially mani- — fest in the young. The prothorax of Tetrophthalmus has above a rounded swelling, and ends forwards in a bristly point on each . Side. Within the prothorax, but visible through the transparent dorsum, is a cross-band of chitin, as in Menopon, for the attach- ‘Ment of muscles. The mesothorax is much narrower than the other thoracic somites. The metathorax is of trapezoidal form, ;. and much broader and shorter than the prothorax. The borders of these somites are strongly chitinized. There are no wings or rudiments of wings. The foremost of the three pairs of limbs are the shortest, and they act as foot-jaws, drawing fragments of -food to the mouth. In the male Tetrophthalmus they are large and also serve for holding the female. The tibia of all the limbs of the male have their inferior end extending into a knob with sharp processes like a “ morning star.” There are only two tar- sal joints, the distal one being the longer and bearing two in- curved claws, inclosing between them a soft lobe [pulvillus]. The es on the tibia and the “ morning-star” processes of the z male serve for holding the female, which indeed often cl among the feathers of the host. ot _ 40domen.—The female of Tetrophthalmus has ten ninal = somi Mites, the terminal one soft and rounded. The male has nine, ¥ uniting into one. The chylus-stomach is cordate at its beginning, — rs 346 Grosses Classification and Structure of the Bird-lice. [ April, as the last is invaginated so as to serve as a sheath for the penis; the hind end of the male is pointed and more chitinized, and more darkly colored than in the female. Digestive track—Two types of crop are found in the Mallo- phaga. In Philopterida the crop is a lateral diverticulum of the cesophagus; in Liotheidz it is a club-shaped symmetrical enlarge- ment of the cesophagus. Kramer divides the intestine of Lipeu- rus into an oral-cavity, an cesophagus, crop, chylus-stomach and hind-intestine. The cesophagus reaches back to the abdomen, and has a homogeneous chitinous intima. The intima of the crop has spines, and its cells appear to secrete a fluid. The chy- lus-stomach extends to the entrance of the malpighian tubules. Grosse finds in the cesophagus of Tetrophthalmus, behind the _ hypopharynx, a chitin-bar produced by thickening of the intima, consisting of a groove-like mid-piece, and running forward and backward into two diverging branches. The hind branches have muscles from the occipital border of the cranium. These chitin- ous bars are not haustellate, but support the oral intima, and in their groove are sent along comminuted fragments of feathers, retained by the retrorse spines and denticulations of the do part of the intima. Goniodes has two squamous cesophageal pieces, a dorsal and a ventfal (Fig. 2, ds, vs). The ventral piece has posterior processes joined by muscles with the occipital border. The dorsal piece sends forward a muscular bundle, which bifurcates and its divi- sions are inserted on the anterior cranial border. Two ducts (probably salivary) run forwards through these scale-like pieces, and has no chitinous intima. The hind-intestine has six longitu- dinal grooves, and rectal glands with richly branching trachee and a chitinous intima. The mode of nutrition of Mallophaga is not fully ascertained. Nitsch stated that they eat the epidermal products of birds and mammals, and sometimes blood. Grosse finds that blood is ~ rarely taken, and only in cases where the bearers (birds) are 59 _ injured or diseased as to have blood among their plumage; an Leuckart gives the same result as to Trichodectes canis of dog. In Lemobothrium, Grosse found the intestine filled with the limbs of its own kind, as if it ate the product of its own > gre: 1886.] Grosse’s Classification and Structure of the Bird-lice. 347 Malpighian vessels —These are four, not branched; have a lumen and ganglion-cells (not separated from the lumen by any membrane). Salivary glands—There are two pairs; and exceptionally the Philopteridas have one-celled glands as on the crop. Grosse found one of these cells undergoing division. The salivary or- ' gans include salivary glands and salivary reservoirs. The glands usually adjoin the crop or stomach, and have a cell-layer with nuclei, covered externally and internally by a fine homogeneous epithelium. Before the entrance of thin ducts into the cesopha- gus, a gland and a salivary vessel unite into a common duct. Sexual organs.—The male sexual organs are of the usual type of insects, paired. testes, spermatic ducts, a seminal vesicle, ejac- ulatory duct and penis. Nerves supply the seminal vesicle and ejaculatory duct; and in Tetrophthalmus the terminal somite of the abdomen is withdrawn so as to be concealed, serving as a sheath for the penis. The female organs consist of paired ovaries (three pairs of ovarian tubes in Liotheide, five pairs in Philop- teridz), two oviducts uniting into one and a seminal receptacle. The egg-case has a lid which springs open at the exit a the young insect, Respiratory apparatus ——There are seven pairs of EE one in the prothorax and six abdominal. Each stigma has internally a crown of fine hairs to protect from impurities. A pair of strong longitudinal tracheæ send branches to the stigmata and are united to each other by a strong cross branch in the abdomen, and smaller ones in the he&d and thorax.

T. CAMPBELL. : F April (1885) I was surveying in the west-central part of -o _ M Parke county, Indiana. On the south side of Section 16, A Township 15 north, of Range 8 west, I noticed that the tree graves were very numerous, there being one to every square rod rer ee oy ce ee we Rs eS eee ae f 1886. | Western Indiana more than 300 years ago. 349 of ground. I noticed that they all indicated that the storm which caused them was going to the north-east. When a tree is blown down the roots hold two to five cubic yards of earth in their grasp, which makes a corresponding pit where the tree stood ; after the fallen tree has entirely rotted, the earth held by the roots leaves a mound resembling an old grave, and have been very commonly called by people here, “Indian graves.” The mound is always on the side of the pit toward which the tree fell. This storm track was about one thousand feet wide. I at that time followed it nearly one mile. Just before I ceased tracing it I found the stump of a white oak, cut down during the year 1884, standing on top of one of the tree graves or mounds, I counted the rings of growth and found it to have been two hundred and ninety-seven (297) years old. That settled the fact that the storm had passed over the ground at least three hundred and ten years before ; for the acorn could not sprout on the mound until the — > tree had first been blown down; and second, it could not sprout till the fallen tree had also rotted away, and left the mound suffi- ciently flattened for moisture to rise to its top surface. - On the 18th of May following I was surveying in Section 29 and 30, Township 15 north, of Range 8 west (which surveyors in the West will understand is about three miles to the south-west of the first place mentioned). Here I also found the tree graves as thick as the grown trees now are, and they also indicated that the storm which blew down the trees which made these tree graves, was going to the north-east. A moment’s reflection also showed me that this was on the same line or track of the one first ob- served. After I returned home I placed a string on my county map so as to cover these two locations, and noted carefully what points > across the county the string touched. I noticed that by extend- | ing the string south-westward it passed about one-half to three- quarters of a mile to the right of Clinton, in the south end of ` _ Vermilion county, which adjoins this county on the west, the — _ Wabash river lying between them. Clinton stands on the west — - bank of this river. I at once remembered that when a boy in my farly “teens” I had lived with a Dr. Kile, two and a half miles South-west of Clinton, and in my frequent trips to town I often A noticed the tree graves, which in my simplicity then I suppo: to be in fact real “ Injun graves.” They were very numer sa 350 Track of a Cyclone which passed over | April, and I supposed there had been a great battle between two hostile tribes of Indians, and that these mounds were the graves of the unknown braves. There were not the very faintest trace of fallen trees in connection with these graves, so thoroughly had they rotted away. I found by applying the string to the map that these graves were in a line with those I had recently found in this (Parke) county. On the 8th of July following (1885) I was making a survey in the north-east part of the county, in Section 29, Township 17 north, of Range 6 west. While at the dinner table I told one of the land proprietors that I had recently got upon the track of an ancient storm which, if it had kept on the course I had observed should pass over the ground we were then eating our dinner on. I asked him if he had ever noticed any trace of it. He said, “Yes. When I was a boy and young man the ‘Indian graves’ out in that field [pointing south-eastward] were so thick that I could jump from one to another all over that part of the farm.” I asked what course the storm was going, and explained how he would know by the position of the mound in relation to the pit. He said north-east, and told me what farms it crossed, and about where it crossed the county boundary into Montgomery county, which was close by. This was over fifteen miles from where I had first discovered the track, and I had not missed its location where I am now speaking about more than seven hundred feet. ~ ae The next day I was going to another part of the county, and had to travel south-westward several miles, and crossed the storm track. -I saw a man in the edge of a field harvesting. I told him g what I had discovered, and asked him if he had ever noticed it. _ _He answered, “Yes. When- I was a boy the Indian (‘Injun ‘) = — graves just below that sugar camp [grove of sugar maples] were as thick as stumps in a new clearing. We boys used to count _ them to see how many Indians had been killed in battle.” It was _ the general belief of the children of the early settlers that these were Indian graves, and that where they were numerous, as in -a storm track, that there had been a battle between tribes. ~ place he pointed out was in the track I was looking after. ~ I may here remark that after the land is cleared and cultivated, _ the plow in a very few years destroys all trace of these graves- _ Hence my inquiries of persons who had known the country from the days when it was an unbroken forest. _ Solved it myself, but not entirely to my satisfaction. I have, after — 1886.] Western Indiana more than 300 years ago. 351 This storm would pass, in going north-east, about two miles to the left of the city of Crawfordsville, Indiana, the county-seat of Montgomery county. Though it might change its course far- er on. At, or very near the spot where I counted the age of the oak which had grown on one of these tree graves, there still stands on another mound a white oak considerably larger than the one I counted, though it may not be an older one. I have delayed writing this account over six months, expecting a miller to cut this larger tree so I could count its age, but it has been neglected so long that I have decided to write from what information I now have. These tree graves are, in the wild forest, as well preserved and as distinct in outline, although more than three hundred years old, as many that have been made by trees that have fallen within my own recollection. If the same conditions that have so well preserved them for that time should continue in the long future, I see no reason why these mounds might not be preserved five thousand, yea, ten thousand years. 3 What does the reader guess has so well preserved these little ; mounds for so long a time? It is nothing more nor less than a thin coating of forest leaves. The leaves act as shingles in shed- ding the rains, so that they are not washed or worn down by the falling rain or melting snow. The frost does not penetrate through a good coating of leaves, and therefore they are not ex- panded and spread out by freezing and thawing. I can see a great difference between the mounds in the wild forest and those On land that has been set to grass and pastured a few years. The tramping of stock and the frequent expansions from freezing, © Which the grass does not prevent, flattens them perceptibly. The grass, however, does preserve them against rain-washings. When a belt of forest is blown down there are no trees to produce leaf shingling till a new set are produced; but these come in great — Sundance in ten years. It requires about fifteen to twenty years {cota sound white oak. The time will depend on the lay of Me log, 2 | whether it falls across another log and lies above ground, _ or lies on or is partly bedded in the ground. a I now offer a conundrum in connnection with this subject for — ©msoever may feel an interest in it to solve. I have partly — 352 Track of a Cyclone which passed over West. Indiana, etc. [April, much observation, noticed that not more than one-tenth of the surface of the present forests show any trace whatever of any storms, recent or ancient. If storms have been as frequent and as destructive in the past as in my day (of fifty-three years), and the elements of preservation of the mounds have existed in the past as now, why do I find so few storm tracks as I have men- tioned? It would seem that in three hundred years, if storms had always been as frequent as in our time, and in the same hap- hazard manner, there would not be a square rod of ground that would not show some trace of a storm. I give my explanation for what it may be worth, but is short of all the facts of explanation. I am able to say of the storm I have | described, with as much confidence as if I had been-present and seen it: First, that it occurred when the trees were in full leaf; second, that there had been a protracted rain; third, that many of the trees blown down were white oak; fourth, that one was a large poplar; and fifth, that very few, if any at all were black walnut. And for the following reasons: The great storms do not now occur before the leaves are on. Without the resistance against the wind offered by the leaves, it is very hard for any li storm to uproot a green tree. If the ground is dry and hard, or < _7 frozen, the trees will break off at or above ground. And in such case they would leave no tree graves, which may account for the few tracks I find. An oak leaves a deep, round pit and a plump, ; round mound. A poplar leaves a broad, shallow pit and a long, _ slender mound, The black walnut is very rarely “blown up by the root.” I have seen this country from an unbroken forest to | — _ the present time, when four-fifths of the land is cleared for the -~ plow or pasture, and I don’t remember that I ever saw a black walnut blown up by the root. I have seen many broken off. | They have a very firm root, and are, when mature, a little -doughty at the stump, but very sound from ten feet above ground upward, : 3 _ I have seen and still know of other large trees which stand on the graves of former fallen trees. Some of these trees are very large, but the size of a tree is such an uncertain indication of its age, that I can’t say with much certainty how long the mounds, on which they stand, have existed. One thing is certain, the = mounds are older than the trees, At the Fair ground, a mile a = west of where I am'writing (Rockville, Indiana) are several such Bye 1886. ] On the Mounting ot Fossils. 353 cases, and on the grounds of the now growing famous resort in our county, “ Turkey run,” or as it is called by people away from here, “ Bloomingdale glens,” are several such cases. In a future article I shall show how the forest leaves have pre- served the sides of hills and thus allowed the small streams to cut out the bottoms of the hollows deep, steep and sharp, which are rapidly changing since the country has been cleared and farmed. Also how they have preserved the ancient beds of streams along the terrace bottoms of the Wabash river and its principal tribytaries till they are as sharply defined after the lapse of no one can venture to guess how many thousands of years, as they were when the last great final flood that cut out the beds Swept over these plains, I have said the storm here described was a cyclone. This I infer from the way the trees had fallen. In some parts of the track the trees were thrown in every direction, and the course of the storm could only be determined by the general course of the track, and not by the fall of individual trees. The course of this storm is. N. 44° 30’ E. in this county. In all my recollection of storms I never saw but one (in 1883) which bore so much to the north, and that one was the most threatening and awful in its appearance I ever saw, and did in localities much damage. Its course was about N. 37° E., or about 7° 30’ more north than the ancient one. The great majority of the storms I have seen, and of those which have left plain tracks, are from a few degrees north to a few degrees south of west. 10: ON THE MOUNTING OF FOSSILS. BY FRANKLIN C. HILL, E five expeditions which have gone to the far West from Princeton have brought in many valuable fossils—invaluable 'S perhaps the better word—chiefly remains of vertebrates. x For the double purpose of utilizing and of preserving these Sastres they have been mounted in a manner new in this coun- wy; and it is believed not common abroad, though somewhat - ced there. The leading idea of the system is that each piece shall be set UP in its natural position. ~ < Museum now contains nearly 400 such specimens, which _ Ki ~ years ago by Professor R. P, Whitfield, and published by me in he W 354 o V On the Mounting of Fossils. [April, have attracted much attention and admiration from visitors, both scientific and lay, and-I have been. often urged to publish some account of my methods and results. Although many fossil bones are whole and clean when found, many more of them are broken and more or less clogged with matrix. The freeing of this last and the mending of the broken are troublesome and delicate tasks. Mallet and chisel come into play, their sizes depending on the nature of the case. For the heavier work ordinary stone-cutter’s tools can be used, yet itis commonly better to make haste slowly and use needles, and no needle is more useful than a No. 1 sharp. By wrapping the eye end of the needle with a narrow strip of paper it can be made to fit in the clamp of a patent sewing haft, and a chisel made, which with a dogwood stick of from one to one and a-half inches diam- eter and nine inches long for a mallet, is capable of doing very delicate work, and also much which at first sight would seem to be entirely too heavy for so light a tool. For reaching into the deeper cavities a No. 12 knitting needle, well set into an awl handle, is needed, while for cleaning out the carapaces of turtles it is well to have special long handles made. Darning needles are of convenient size but of too poora quality. of steel. But whatever needle is used, a good oil-stone should always be. at hand to renew the point as often as it is blunted. By a little practice a point can be put to a needle much better for this work than the original one. A good stiff tooth-brush is needed, a good lens, say Tolles’ one inch triplet, anda hand mirror to throw light into cavities of heavy specimens that cannot be easily turned. ew A high workbench with vise, plyers, anvil and hammers, drills, a flat cushion to lay specimens on while being worked, and an assortment of wire complete the “kit” of tools, but a pot of mucilage and a box of calcined plaster are also needed for mend- ‘ing the broken. It is best to have always a number of specimens on hand so that the mended can be allowed to dry without delay to the work. _ Of the cements that we have tried at Princeton, we have give® | up all but the one which we began with, recommended to us the Am.

Latterly we have added a small quantity of salicylic acid to prevent fermenta- tion. It should be about as thick as honey, and for joints that do not fit neatly it is well to thicken it at the moment of using | with plaster of Paris. For filling large voids plaster enough should be kneaded in to make a stiff putty, and it is well to work in with it as many pieces of stone or brick as possible, both to Save material and to lessen the shrinkage of the mass. Although I sometimes paint the masses of plaster which show i themselves, to destroy the unpleasant violent contrasts of color, I always use some neutral tint entirely different from the color of the fossil, in order that the false parts can be easily ‘distin- guished, With the outfit described, a smooth-grained and moderately hard matrix and good hard bones the work is pleasant and easy. But when the matrix is of cemented gravel, here hard as flint, there loose sand, with soft and crumbly bones, a large stock of patience and good temper must be laid in also. When the bone is freed from the matrix and mended, the ques- tion comes up as to how to keep it safely and show it to advan- tage.

Of course the block must always be just so large that no part Fiz 1 of the bone will overhang the edge, and then the specimen will not be injured by crowding it against _ the wall or another specimen. If larger than needed it wastes shelf-rcom. If the specimen be large and i ) heavy, or at all crumbly, the supports need to be tig 2 wrapped with cloth or felt to protect it. y Suppose wè have both rami, or the greater part of them. Mend the breaks with the cement, and when dry bend two stout wires as in Fig. 2, one to bind the jaws together at each end, cement them in place and let them dry. Then set up three wire hooks to receive these braces, as at J and c, Fig. 3, one in front and two behind, as far apart as the jaw will allow. The use of these hooks is so obvious that the most careless or dull stu- dent can hardly fail to see it, which is a good thing, because if a Skull and atlas, eight and a half inches long. blunder be possible some persons can always be depended on to make it, and hence come many breakages. If beside the jaw we ‘have the skull, we need two more wires, one to catch the back of the skull at the glenoids (Fig. 3 d), and the other to support the oe nose (a). In this specimen the sixth wire (e) carries the atlas, as shown in Fig. 4.

Here are almost all the parts of Hyznodon’s hind leg and foot, with part of the pelvis, a chaos as they lay in a tray. But by first glueing the tarsals together in position and making them a bed on a plaster base, and then bedding each metatarsal and phalanx in turn, I was able to display the foot. The tarsals were then set free by soaking in water. Fastening this plas- ter base to the black walnut pedestal by a screw-bolt, I set up behind it a post, eighteen inches high, into which wires were set, as Shown in the figure. The small figures behind show the wires as seen from above “in plan.” The main curves in æ and å hold the tibia and their ends catch the fibula.

Each bone is marked with the museum number of the Specimen somewhere on its surface. z The adjustment of these wires is a nice matter. Each bone must have its natural position, but must be under no strain ; must be held in its place securely, and yet be so free as to be easily lifted out. It must stay by gravity only.

When a new curve is put into one end of a crooked wire the path of the other end through space defies mathematics. With heavy bones it is sometimes hard to make them rest in their supports without strain, though it can be done. We have an enormous femur of a mastodon which seems to be held up by a post behind it, while really the whole weight is borne by a plas- ter base in which the condyles rest, and the upper end does not even touch the post or the guard wires.

This gives room for a good sized label on the side, giving genus and species, geological formation, locality and cata- logue number. For very small jaws, single small teeth, &c., I set up a small cylinder of plaster on one of the smallest pedestals, and cement the specimen to the top of it. In other cases, as in Didelphys pygmea Scott, and the Acip- tion jaws shown in Fig. 8, the slab of matrix is cemented to the surface of a board hung on two Fig: 5 Pivots, so that it can be tilted to either side for ex- 3 Roars examination. And when a new specimen shows new features I devise a new mounting to suit them. :0: RECENT LITERATURE. CROLL’S CLIMATE AND Cosmo.ocy..—In this volume of essays, Mr. Croll reaffirms his physical theory to account for the glacial climate in a way to command the attention of every geologist and in a manner which will attract the interest of the lay reader. The discussions relate to questions of the deepest interest, and the arguments used are certainly strong ones. Mr. Croll’s peculiar views as to the existence of glacial climates before the Quater- nary period are restated with much fullness, though he candidly ie x admits that most geologists are opposed to them. 4 bi € author’s theory is usually called the “eccentricity theory,” _ ut he prefers t#call it the “ physical theory.” He states thata h state of eccentricity of the earth’s orbits will not necessarily a * Discussions on Climate and Cosmolo, B -DF R.S.

But all this depends on ocean-currents flowing from equatorial to polar regions, and the existence of these currents, in turn, de- pends, to a large extent, on the contour of the continents and the particular distribution of sea and land. Take, as one example, the Gulf stream, a current which played so important a part in the phenomena of the glacial epoch. A very slight change in on a former occasion, a change in the form or contour of the Northeast corner of the South American continent would have deflected the great equatorial current, the feeder of the Gulf stream, into the Southern ocean and away from the Caribbean sea. One of the main causes of the extreme condition of things 1M Northwestern Europe, as well as in eastern parts of America dur- ing the glacial epoch, was a large withdrawal of the warm waters of the Gulf stream, and this was to a great extent due, as I stated in my first paper on the subject to the position of Cape St. Rogue, which deflected the equatorial current into the Southern ocean. That a geographical distribution of land and water, per- i mitting of the existence and deflection of those heat-bearing cur- - rentṣ is one of the main factors in my theory, is what must be — obvious to every reader of Climate and Time.” Dr. Croll maintains that, with the exception of those resulting from oscillations of sea level, the general distribution of sea an nd and other geographical conditions were the same during the _ glacial epoch as they are at present. Thus he does not accept Lyell’s theory of an elevation of northern lands; yet we do not see but that this was a matter of fact. Indeed, Mr. Croll’s specu- lations produce the impression that he is somewhat one-sided in his treatment of these theories. His knowledge of general geol- ogy, and especially of palzontology, is apparently slight. For as _ regards his theory of interglacial climates in times preceding the | vcs Quaternary, the view is opposed to the whole »mass of facts 1n ~ palzontology. The more we have read of Dr. Croll’s eccentricity _ theory, the less necessary does it seem; the geologist had better : 1 Philos, Mag. for August, 1864. 1886] Recent Literature. 361 rely on purely geological causes ; they may yet be proved to have been sufficient. Dr. Croll nowhere explains why so large a por- tion of the subpolar regions were unglaciated. In his discussions in cosmology, Dr. Croll contends that Sir William Thomson and others are wrong in maintaining the “gravitation theory,” z. e., that the sun cannot have supplied the earth with heat, even at the present rate, for more than about 15 to 20,000,000 years. He discards this theory, and freely gives the evolutionists and geologists all the heat they want, by claim- ing that the sun’s heat was originally derived from motion in space; this being “ more in harmony with the principles of evolu- tion than the gravitation theory, because it explains how the enormous amount of energy which is being dissipated into stellar space may have existed in the matter composing the sun untrans- formed during bygone ages, or, in fact, for as far back as the matter itself existed.” On page 65, Dr. Croll, it seems to us, too hastily assumes that the ice in the interior of Greenland is of great thickness, while the land itself is low, “ probably not much above sea-level.” On the contrary, as the result of recent Danish exploration, Dr. Rink tells us, the surface of the ice in the interior is 6000 feet above the sea, while we infer from his statements that the thickness of the ice is not much over 2000 feet. In fact, the theoretical gla- Cialists go to extremes ; closet speculations and field-work do not always harmonize. The only typographical errors we have noticed are the mention of “Heyes” for Hayes on one occasion, while Torell is wrongly spelt “Torrell,” in the only instance in which it is used.

Edward’s great work for nearly all the descriptions of the early stages, and follows the classification and nomenclature of that author. The criticisms we have to make are slight.

GEOGRAPHY AND TRAVELS.! America.— The Goajira Peninsula—F¥. A. A. Simons contrib- utes to the Proceedings of the Royal Geographical Society an account of the Goajira peninsula, to the west of the Gulf of Mara- caybo, in the United States of Colombia. This large peninsula appears to be tenanted only by less than 25,000 Indians, who are divided into several castes, and have some peculiar laws. Every ‘ Indian belongs to the tribe of his mother, and, if he injures him- self in any way, he has to pay blood-money to his mother’s rela- tions for shedding the blood of his family, and tear-money to his father’s relatives for the sorrow he has caused them. The south- ern part of the peninsula is a level, grassy plain; the northern, a country of volcanic hills, with three ranges, the highest about 2800 feet high. There are no perennial rivers on the peninsula, So that in summer—the greater half of the year—the only water is from wells and a few water-holes, natural or artificial.

Considerable interest attaches to the discovery of an Anchi- therium and of a Merycochcerus at this locality, as these genera ally the epoch to the John Day period, while Hippotherium, Dicotyles and Protolabis are Loup Fork genera. he Anchitherium ultimum is represented in my collection bya nearly complete superior dentition, with palate and sides of skull to the middle of the orbits, and top of skull to above the infra- orbital foramen. The size is less than that of the A. prestans Cope and A. eguiceps Cope (? A. anceps Marsh) of the John Day bed, and the dental series has the same length as that of the A. longicriste Cope, also of the John Day. It is in the cranial characters that this species displays the greatest differences from the John Day species. In the first place there is a profound and large preorbital fossa, separated from the orbit by a vertical bar. The preorbital ‘fossa in the John Day species is shallow, and not abruptly defined. In the next place e anterior border of the orbit is above the anterior border O the last molar tooth. In this it agrees only with the large A, prestans ; in the A. eguiceps and A. longicriste the anterior border ‘of the orbit is above the anterior part of the second superior molar. Thirdly, the infraorbital foramen is above the middle of the fourth premolar; it is over the posterior part of the third in the three John Day species. Finally, the nareal notch marks the anterior two-fifths of the diastema; it extends much further back in the John Day species, marking either the front or middle of the first premolar. The palate extends about as far anteriorly as 1n - A. prestans, viz., to opposite the posterior border of the first true premolar. : y known spe- , about equaling the larger individuals of The molar teeth are, however, relatively the anterior premolars and incisors smaller and more crows” The last two premolars are in line, but the second premolar is sêt ee ae what 1886.] Geology and Paleontology. 369 outward. The symphyseal suture is short and rather deep. Its posterior edge is below the posterior quarter of the third premolar.

This animal is one of the deer-antelope, with persistent horns and deer-like dentition. Its horns are long and stout, and have a wide basal expansion above the posterior part of each orbit. It is about as large as the black-tailed deer. The Ticholeptus horizon is interesting as that in which the genus Mastodon makes its first appearance in America.

The principal forms are well illustrated. As a provisional arrangement the Palzodictyoptera, as thus limited, may serve a temporary purpose, but the wonderful discoveries of Brongniart at Commentry, in France, seems to us to forbid the adoption of such a division, and to favor Brongniart’s view that many of them, except Eugereon and possibly others, are simply Paleozoic gen- era of existing orders of insects, č. ¢., representatives of distinct and extinct families, rather than of lost orders. But Brongniart's discoveries were not placed in the hands of the scientific public until after the work before us was mostly in print. Some of the divisions, as the Coleopteroidea, for the unknown manufacturer of the suborder Pseudoneuroptera is inexplicable to us, now that their structure is so well known. ; But however one may differ from the author in matters of classi- fication, he can not fail to note the care, labor and learning which has been bestowed upon this excellent and most useful summary. Oscar SCHMIDT ON THE ORIGIN OF THE DOMESTIC Dos.'—We must now refer to the question of the origin of the domestic dog. That the whole line of foxes has nothing to do with the dog has long been an established fact. On the other hand Darwin en- deavored to prove that various wild tribes of men in different rts of the globe tamed native wolf-like animals, and that ae crossings of these species and breeding of various kinds produc the domestic dog of our day. This cpinion of Darwin has been , somewhat modified by L. H. Jeitteles, a careful authority on the domestic animals. According to him the wolf ( Canis lupus) has no connection with the European and west-oriental races of dog _the connection being mainly through: the jackal and the nawt -wolf (Canis pallipes). The races partly lead back into prehistorie times. l osest to the jackals we have the so-called turf-d0gy known from the turf deposits of the lake-dwellings, and which § probably the ancestor of our Pomeranian dogs. Allied to it we have the terriers and turnspits. From Canis pallipes is descend the so-called dronze-dog, which most. probably came to Europe with human immigrants from Asia, and with it the sheep dog bull-dog. The ancestor of a third group may perhaps be found in the large jackal (Canis /upaster) of North Africa, to which ya _1The Mammalia in their relation to primeval times. New York, D.

According to Blain- ville’s opinion, a diluvial species of a gentle and sociable nature— no longer existing in a wild state—must have been the primeval form of the domestic dog; but after what has been said above, wild forms of the Canide of the Diluvium, and herein he agrees with what Darwin and Huxley have. stated regarding the bi between the domestic dog and the living jackals and wolves, It may with certainty be maintained that the direct ancestors of the European wolf are to be found in the Diluvial deposits. Formerly a huge animal of the wolf species was distinguished as the cave-qolf, without there being any distinct character to sepa- tate the two forms. A third form of wolf (Canis suesstt, from the In now returning to the living Canidz, several species demand Our attention, one of which is described as Jcticyon venaticus, a ing the countries to the north and north-east of the Altain moun- tains, ese dogs do not possess the third molar in the lower toe Ti Sonne 372 General Notes. [April, velopmėnt of new genera of beasts of prey began with dog-like imals. ; : Much more interesting for the purpose of our investigation here is the Otocyon lalandii, the spoon-dog of South Africa, so called from the peculiar formation of the skull. Its habits show an approximation to the foxes, yet as regards dentition it does not show this affinity, inasmuch as it possesses 4:4 molars, and also shows the most remarkable differences in the relative size of the single teeth. As already said, the spoon-dog is, in many ways and as regards dentition, shaped after the fashion of the dog type, and can thus scarcely be dragged out of this connection, and we are compelled to look upon it asa still existing primary form of dog. The whole paleontology of the vertebrates shows that the many-toothedness of mammals is an inheritance from their lower ancestors, and that any increase of the teeth within a class has probably never taken place. As our dogs, with their 2:2 molars, have no doubt been de- scended from fuller-toothed animals, Otocyon must be regarded as the still-living representative of the early type of dog, which very small frontal depressions, it is, as Huxley says, very di í cult not to imagine that these too must be traced to ancestors © the Otocyon type. From this species, therefore, we should have to derive the two lines which diverge into the fox on the one hand, and the wolf on the other. We are supported in this view by the observation that the South American Cams eet often possesses the fourth molar, and thus shows itself to another remnant of the primary form. A fourth supernumerary molar of this kind is not a monstrosity or pathological phenome non, but an atavism or reversion of the same sort as the so _called wolf's tooth in horses, which was explained as a premolar which existed in the primary genus Anchitherium. i a - Hence the key to the derivation of all the dog tribe is to found in their relation to the spoon-dog. ey GEOLOGICAL News.—Si/urian.—S.

The Lacertilia are represented by Telerpeton, Hyperodapedon and an undescribed form, Crocodilia by Stagonolepis, and Dicynodontia by the type genus. Dr. Judd and Dr. Gordon have now procured good evidence that this rep- tiliferous sandstone passes down into a bed of conglomerate which rests unconformably upon the strata of the Upper Old Red sandstone. The conclusion is that during the vast periods of the Carboniferous and Permian, the Upper Old Red sandstone of the Elgin area was upheaved and denuded, and the Upper Trias beds deposited unconformably upon their eroded surface. ; Jurassic and Cretaceous —MM. Bertrand and Kilian, who have studied the Jurassic and Cretaceous strata of Andalusia, report that their composition is very like that of the same beds in the Alps. There are also many analogies between them and the cor- responding beds of Sicily and of the Apennines, while the upper beds resemble those met with in the Balearic islands.

Hussak’s “ DETERMINATION OF ROCK-FORMING MINERALS.”"— The appearance in English of any book which treats of the methods of the new geology, is a subject for congratulation on the part of those who believe that the use of the microscope will globe and to the changes which these rocks undergo under vari- ous conditions, It is a lamentable fact that, though so much is now being done in this field, but few good English text-books exist. The only works relating to this subject which have appeared in English are Zirkel’s Microscopical Petrography? and Rutley’s Study of Rocks. Both of these treat more par- ticularly of the classification of rocks and presuppose a know- ledge of the elementary principles, by means of which their mineral constituents are recognized. It is with pleasure that we now welcome a third volume, which treats of the optical proper- ties of minerals and the methods which are made use of in their detection. Dr. E. G.

These are placed vertically in groups, according as their cross-sections are isotropic, or show parallel or inclined extinc- tion. These groups are again subdivided in accordance with the crystallographic systems. Opposite the name of each mineral are placed its chemical composition, specific gravity, characteristic cleavages, the ordinary forms of its cross-sections, its twinning laws, the character and strength of its double refraction, its colors under crossed nicols, its natural color and pleochroism, its struc- ture, the minerals with which it is generally associated, its char- acteristic inclusions and decomposition products, and those pecu- liarities which distinguish it from other minerals of the same general appearance. In this part an immense amount of material is so arranged that with very little trouble the student can turn to the mineral whose properties he wishes to study, and find in a few brief sentences the characteristics by which it can be distinguished from all others. This part will prove of considerable use to all who are beginning the study of petrography, and whom such manuals as that of Rosenbusch would tend only to confuse and discourage. A great service has been rendered to all those to whom the material in Dr. Hussak’s book is inaccessible on - account of the language in which it is written, and the translator deserves the thanks of all those interested in petrography for having placed within the reach of American students the elements of a branch of geology which is just beginning to be appreciated on this side of the Atlantic, as affording a key for the solution of many questions which have heretofore been considered as beyond the power of penetration.

Hydrotephroite is a mixture in various Proportions of at least three different substances. That which Occurs in greatest quantity is colorless and biaxial and is probably tephroite. The other substances are serpentine, chlorite and various manganese minerals. The hydrotephroite is probably an altered tephroite or some other manganese silicate. Beautiful rhombohedral crystals of calcite are described by R. H. Solly,? from the Tankerville mine, Shropshire, Eng. They contain only the rhombohedral and scalenohedral faces, with the former pre- dominating. The scalenohedral faces are bright and are cov- ered with little quartz crystals, while the rhombohedral faces contain no quartzes, but are dull and corroded. Until very recently our knowledge regarding the blue “sulphato-chloride of copper,” to which Dana in 1850 gave the name connel- lite, has been confined to the results of the investigations of Maskelyne? and Bertrand.* Lately, however, in consequence of discovery of new material, the crystallography of the mineral has been thoroughly worked up. Connellite occurs in copper veins traversing clay slate and granite in the Camborne district, situated at the west end of the granite boss in which most of the Productive tin mines in England occur.

A free swimming on the surface, like that of diatoms, was never observed. The first two of these movements depend on the formation, during the motion, of a filament of mucilage, by which the des- mid is attached to the bottom; the gradual lengthening of this filament, by the formation of fresh mucilage, causes the desmid to rise. The filament is best detected by a weak solution of methyl- violet or fuchsin, which does not kill the desmid. Cyanin also answers, but not so well. Other pigments do not stain it, Many species of Euastrum, Cosmarium, Staurastrum and Pleurotenium exhibit the same phenomenon. The greatest length of filament observed was 3™™; the most rapid motion, in Clostertum acero- sum, 112" in 30 sec.; many species are quite motionless. Light exercises an influence on the direction of the movement similar to that of zodspores, but not on its rapidity. The elevation and depression appear to be independent of the direction of gravita- The author considers the cause of the motion to be the exuda- tion of mucilage, which does not take place simultaneously and uniformly over the whole surface of the desmid. This formation of mucilage is not the result of disintegration of the cell-wall itself; it proceeds directly from the cytoplasm and passes through the cell-wall without the latter undergoing any change. Many species are completely surrounded by a gelatinous envelope, while others are comparatively free—A. W. Bennett, London. PLEOMORPHISM OF AtGa&.—Dr. A.

[April, superintendent of the Government cinchona estates at Mong- phoo, near Darjeeling, has noticed the same thing with regard to the allied Northern species, Micropternus phaloceps, and the pecu- liarity probably extends also to the allied species found in Bur- mah, Siam, &c. : r. Gammie thinks that when an ant’s nest has been taken pos- session of by the bird that the ants desert the nest. This is a point on which I cannot, speak with certainty. Mr. Gammie has taken nests of the Northern species in which, although the bird had laid, the ants remained, and he has taken other nests where not a single ant remained, but there is nothing to show that these nests were not deserted before the bird took possession. I, my- self, have taken nests of the Southern form, in which, though the eggs were partially incubated, the ants remained, showing that some considerable time must have elapsed since the bird took possession. This is a point that I hope to be able to elucidate within the next few months, when the birds will be breeding. When Micropternus is breeding, the feathers of the head, tail and primaries of the wings are yet covered witha viscid matter, having a strong resinous smell, and this substance is usually rather ye studded with dead ants (vide “ Stray Feathers,” Vol. VI, p. 145). | Two specimens of kingfishers also to my knowledge nidificate in ants’ nests, viz., Halycon occipitalis, confined to the Nicobar islands, and Æ. chloris, which ranges from India as far south as Sumatra. : At Mergni, in South Tenasserim, I found a nest of Æ. chloris in a hornet’s nest, and although I saw the birds repeatedly enter the hole they had made in the hornet’s nest, the hornets did not seem to mind it; but they resented in a very decided manner any attempt to interfere with the nest.— Wm. Davison, Nature, March 12, 1885. Tuer Soarinc oF Birps.—Mr. Hendricks, in the NATURALIST for March, intimates that I misinterpret the phenomenon of soar: ing, “for it is well known that the upward lateral force would | arrest the downward motion, so that the cause of the upward motion would be immediately withdrawn.” It would seem that the “ downward motion” could only be arrested by resisting the lateral force. On his own showing the gravity _ of the Jody cannot do it, as this “ is descending uniformly through tance equal to its weight” There is no air condensed nor driven out of the way in the lateral motion, so that the only resistanc® to the lateral force is that of -atmospheric friction on the sm surfaces of the plane, and this is very little. = To enable the weight to resist the lateral force it would have _ to be created, as the original amount is fully occupied. aan ra we —1886.] Zovlogy. 391 As action and reaction are equal and opposite, and normal to the falling surface, the inclination in which that surface lies is a neutral plane, and no amount of force acting in that plane can increase or diminish its downward motion. It is obvious that an incident force at any angle whatever from any direction above the plane would increase the fall, and at any angle or direction from below would diminish it, while in the plane, from any direction, its motion would neither be increased nor diminished but remain unchanged. There would simply be a motion added to the body, in its own wey in the direction of the impressed force and proportional oit I can detect no “error” arising from “a misconception of the phenomena of resulting motion.” The body falls with uniform Speed, constituting one of the factors of soaring. It is then -moyed laterally on an upward incline, which is the other factor. _ These result in the level motion of flight in obedience to the law of all resultant motions.

A narrow diverticulum from this passage is continued forwards for a short distance along the axis of the notochord. After traversing the notochord, the pass- age is continued into a hypoblastic diverticulum, which opens ventrally into the future lumen of the alimentary tract.” It is clear from the figure that this must have been the case in the specimen here under consideration; that is, the neurenteric pass- age about which notochordal tissue was differentiated was con- tinued forward into the chorda, as the latter was folded off from the hypoblast, and that from this passage in the chorda one pass- ing downward to the intestine was given off about which noto- chordal tissue was also differentiated. . While it is highly probable that this embryo chick displays an archaic development of the chorda, yet the facts are significant, especially when viewed in the light of the interpretations of - Ehlers as to the significance of the “ Vebendarm” in the inverte- brates.

[ April, blood was drawn from each vessel, all albuminous matters were precipitated with great care, and the fluid remaining was tested, after concentration, as to its content of nitrogen. The author dis- cusses fully various methods employed in the separation of minute quantities of albuminous substances from complex mix- tures. The results of these experiments indicate a very consider- able destruction of peptone by the liver with the formation of a corresponding amount of a nitrogenous product of the decompo- sition. Seegen was led to the choice of peptone in his study from the fact that Schmidt-Miilheim had found that most of the albumi- destruction of peptones. In respect to the formation from pep- tones of carbohydrates by the liver, the author found that, in experiments performed in the manner described above, not only was the sugar content of the peptone-liver-blood increased 20-70 per cent above the liver blood without peptone, but the total amount of carbohydrates was increased as well. The conclusion is reached that the function of the peptones, at least in carnivor- ous animals which are not changing in weight, is, for the most part, to give rise to the formation of sugar in the liver. In another article the same author discusses the influence of ees variation and nature of the food supply on the presence of sugar in the blood. In the hungering animal (dog), the blood of the hepatic vein is constantly richer in sugar than that of the portal vein, the relative amounts being nearly two to one.

The blood _ of the hepatic vein always contains a larger percentage of sugar eo 1886.1 Physiology. 399 than that of the portal vein, not only during hunger, but after all manner of carbohydrate diet. The formation of sugar in the liver has nothing to do with the sugar ingested with the food. The for- mation of sugar by the liver persists throughout a prolonged period of inanition, and is not increased when a large amount of carbohydrate is fed to the animal. Seegen does not believe that the glycogen found normally in the liver is the source of the sugar of the hepatic vein; it probably has some special destiny, perhaps the formation of fat. The amount of glycogen found in the liver stands in very close relation to the amount of carbohy- drate in the food.— Pfiiger’s Archiv., 1885, pp. 325 and 348. PLETHYSMOGRAPHIC AND VASO-MOTOR EXPERIMENTS WITH FROGS. —Dr. Ellis has followed Drs. Bowditch and Warren in a series of investigations which bids fair to open the way to much that is new and-yaluable concerning the vaso-motor mechanism. The latter observers studied by the graphic method the variations of volume produced in the hind leg of a curarised cat by electrical Stimulation of the sciatic nerve. The volume of the limb was measured by the plethysmograph, and any fluctuations in it could o due to variation in the amount. of blood supply. The authors found when the peripheral end of the nerve was excited by rapidly repeated induction shocks (16-64 per sec.), there was usually contraction of the vessels. When a slower rate was employed (4-0.2 per sec.), there was dilatation. With a medium rate of stimulation there followed first a narrowing and afterward a dilatation. A latent period of 1.5 sec. preceded the constriction, and one of 3.5 sec. the dilatation. The latter effect sometimes per- sisted for several minutes after cessation of the stimulation, but the former usually ceased with it. By an exceedingly ingenious application of a test-tube ple- thysmograph connected with v i ours, Dr, Ellis has been able to study the vaso-motor changes ing the varying effects of electrical stimulation upon the blood-vess à = greater the tendency to immediate dilatation. 2.

These experiments indicate the existence of two separate per- ipheral vaso-motor mechanisms, one having the function of vaso- constriction, and the other of vaso-dilation—Zhe Journal of Physiology, Vol. vi, p. 437. PSYCHOLOGY. _ANTHROPOLOGY AND PsycHotocy.—At the Aberdeen meeting of the British Association for the Advancement of Science, Dr. Alexander Bain, lord rector of Aberdeen University, read a paper “Qn the scope of anthropology, and its relation to the science of mind.” He endeavored to point out that the bringing together of the six departments—named respectively man’s place in nature, i the origin of man, the classification of races, the antiquity of man, he language and the development of civilization—did not contribute ee to the mutual elucidation of the several topics, but merely concen- trated into a whole the subjects connected with the higher mys- teries of man’s origin and destination. He next dealt at length with a survey of the researches having in view precise measure- ments of the bodily and mental characteristics of human beings, and indicated lines on which research might be made so as to also reverted to the research into the conditions and the measure _ of memory as wholly within the means of actual experimenta determination ; also the important intellectual function of seeing similarity in the midst of diversity, which can be reduced to more or less precision of estimate by suitable means. Taking along with these results the inquiries into the faculties of the lower _ animals, the author put special stress on the number and delicacy =- Of their senses as the foundation of every attempt to explain the _ — higher aptitudes. Intelligence commenced with the power of dis- crimination, and increased as that power increased. The record of marvelous feats of exceptional ingenuity was of very little aid in revealing the secrets of the animal mind, In conclusion, he urged the admission of psychology in a more avowed and sy -© matic form into the anthropological section. He would exclude _ the topics of metaphysical and ethical controversy, and welcome ~ all the researches into the intellectual and emotional regions of _ the mind, Dr. Burdon Sanderson said any one teaching physt- _ ology would not be expected to include anthropology, and Dr. a Bi aeRO a e ie a een Lak tb Sat a tes a iS a: a ae Re ge ae en eee ee Pee x = Maton: Phiterons m ~ €aten for itch. tee - : Edited bi Prof. Oris T.

That was because when we came to the higher functions of man, called mental functions, we had to do with perceptions which were founded upon sensa- tion, which meant interpretations by the mind of those percep- tions. He considered that the line at which physiologists stopped was the line at which Dr. Bain begins—namely, measure. He heartily agreed with’ Dr. Bain in thinking that psychology is the subject that lies at the basis of anthropology, and should be accepted as its foundation. ties. The committee on thought transference has collected the re- sults of some twelve thousand experiments conducted by a num- T of observers, and a statistical study of these seems to show a slight preponderance of right guesses when the conditions are such as render thought transference possible. A special committee has been inquiring into the subject of faith-cure ; but without attaining anything in the way of positive results. Some of the most frequently described cases of marvel- ous cures were, on investigation, found to be without any suffi- cient basis in fact. In general, the “ faith-curists” seemed to . dread and abhor anything like a scientific investigations of their. - claims; so that any careful study of the psychic phenomena which attend the cure of even those nervous and illusive maladies that _are known to be amenable to mental impressions, was out of the question.

Tue REVUE p’ANTHROPOLOGIE—The most celebrated of the many French journals devoted to the science of man, was founded in Paris by Paul Broca, in 1872, and continued by his pupil, Dr. Paul Topinard, after the death of the former. A third series was commenced -with 1886 with the coöperation of the most dis- are tinguished representatives of the various branches of anthropo- , ` logical science; among them Dr. Gavarret, director of the Ecole d’Anthropologie de Paris; Dr. Mathias Duval, director of the Laboratoire d’Anthropologie a l'Ecole des Hautes Etudes; Mar- quis de Nadaillac; General Faidherbe, High Chancellor of the Legion of Honor; Professor A, de Quatrefages, at the Museum of Natural History; Dr. Hamy, of the Musée Trocadero; L. Rousselet ; Jules Rochard ; Baron Savoy and D’Arbois de Jubain- . ville, of the French Institute. Dr. Topenard, the director of the ee Revue, is general secretary of the Société d’Anthropologie de : Paris, and author of the Eléments d’Anthropologie, to which the Académie des Sciences, awarded one of its annual prizes. Tue Races or Men.—The latest attempt to find a rational expression of racial differences among mankind is by Mr. James Dallas, curator of the Albert Memorial Museum, Exeter. The author is in accord with the general tendency to see three princi- pal groups of humanity, as follows: ochroi, represented by the European, Mesochroi, represented by Mongols and American Indians. . ans. Æthochroi, represented by Negroes and Australi = In the Æthochroic group, Mr. Dallas would include Berbers, _ Nubians.

A yet greater elevation would convert the Bay ot Bengal into dry land, join the Andamans to India, the Laccadive and Maldive islands to Arabia, converting the Arabian sea into a broad expanse of nearly level ground.” At the same time a great geological barrier would be erected against the northern movement of this type. “Thus we have an ‘area to no small extent demonstrably cut off from the northern regions of Asia and Europe, in which alone traces of the Aithochroic group are to be met with, and the A:thochroic peoples were originally the sole occupiers of this area.” Mr. Dallas relies largely upon facts developments, one in Africa, the other in the Philippines and Andamans, almost pure, still exist. In the other areas the stock is much mixed. Roughly speaking, the Leucochroic group occupies the whole of Europe with the exception of a part of the northern portion, and parts of Hungary and Russia. Eastward, members of this group exist in the Caucasus, Armenia, Persia, Georgia, Circassia, ; Afghanistan, Kashmir,and Hindustan, Kattiwarand Rajputana,and A include the Siah Posh Kafirs of the Indian Caucasus, and remnants in China, Tartary, Japan, Kurile island and Kamtshatka. Indeed, Mr. Dallas looks for the origin of this type in the heart of what is now the Mongol area, the plateau of Central Asia, believing that they extended along the eastern coast of Asia from Kamt- Shatka on the north to the limits of the Æthochroi on the south, rom this central region the Leucochroic race passed westward by the great depression, the Zungarian strait, to overrun first Western Asia, and eventually the whole of Europe, branches - | marmot are taken as parallels among mammals.

[April, ANTHROPOLOGICAL News.—A German treatise of Ernst Kuhn “on the origin and languages of the transgangetic nations” was published in the Transactions of the Bavarian Royal Academy (1883, pp. 22, 4to), and gives a lucid sketch of racial and linguis- tic facts observed in China and Indo-China by recent investiga- tors. Kuhn thinks that the autochthonic population of the Indo- Chinese peninsula are the people of Annam, Kambodja and Pegu, and that the intruders who drove them to the coast, came origi- nally from Western China, like the Tibetans; that the monosyl- labism of all these languages is not original, but only the result of condensation of a former polysyllabic status; that the Tibetan language has retained the most Arabic forms of the western group of dialects ; that the Kambodja is not a Malayan language, as it has beenasserted by Aymonier and Keane; that the series of numerals proves ancient affinity of Chinese with Barma (Bur- mese), Siamese, Lepcha and Tibetan. — The Lord’s Prayer, translated by E.

The table is supported by four Square wood frames which together bound a cubical area, as shown in the figure. A pane of glass, fitted with a frame, repre- sents the upper surface of the cube, while the five other sides are open so as to admit of the frame with the plate being placed upon any side of the cube. On the lower frame Schroeder’s stee pincers are fitted, by means of which the object may be placed in such a position as to be completely detached and visible from all sides. These pincers firmly grasp the object; this is effected by fastening a screw and by three sharp points. The axis of the pincers has a bilateral clamping movement, which may be regu- # lated by means of a screw; then there is around bar fixed on = two opposite sides of the lower frame, on which a vertical rota- tion of the axis of the pean and a horizontal sliding movement = of the object can take pla able by means of a special screw and admitting of a horizontal rotation of the object.

CONN, PH.D. Ee theory of evolution implies a past, a present and a future. Since the time of Darwin the past and present of the organic — world have been studied with the result of showing that the his- tory has been one of evolution. Having now reached this con- clusion, and having discovered many of the laws of advancement in living nature, we are getting into a position where we may ' begin to study the future. It is the object of this paper to indi- cate certain limits in development toward which the organic world have long been tending. The idea of evolution implies that there has been a gradual tise in the scale of organisms from the lowest to the highest. But when paleontologists have attempted to show this gradual tise by a study of fossils they have had much less success than | the theory of evolution would lead us to expect. That there has p n a general advance from the earliest fossils in the Silurian until r now, seems unquestionable. But instead of being the most pal- pable result of study, this advance is so obscure as to cause sur- Prise to all who have attempted to make it out in detail. Darwin expressed his surprise at the lack of evidence, and the difficulties ve increased rather than decreased since he wrote. In some groups ther€ has been an undoubted advance; the vertebrates, for : instance, showing this in a marked manner. In a majority of Sroups, however, we do not find it, for while the animals have not in any case remained absolutely stationary, the development, as a — me has consisted chiefly in the increase and diversity of species - and genera. It is a matter of continual surprise to naturalists to n ONS ees. e ER 414 ; The Limits of Organic Evolution. [May, find constantly increasing evidence of the great diversity of life which must have existed in the Silurian era. With the advance of our knowledge of these earliest fossiliferous rocks, new groups are constantly being added to the already extensive fauna. Our knowledge of these times is still very scanty, but even now we oe know that the fauna was highly developed. All of the subking- | doms of the animal world were represented, about five-sixths of the orders and suborders of the present time, many families and afew genera. Bearing in mind the necessary incompleteness of our collections, we must conclude that this fauna contained rep- resentatives of a large proportion of the animals now existing. Nor were the various groups represented by these lowest types simply. The Ccelenterata contained Hydrozoa and Actinozoa; among echinoderms we find echinoids ; among mollusks we find cephalopods; among Arthropoda were Tracheata in the shape of scorpions, And while these types were not developed as highly A as they are now, their mere existence is enough to indicate that already a large advance in the evolution had taken place. If this t is the case it becomes plain that evolution since that time has been almost entirely confined to the elaboration of the groups then existing. Now we are not at liberty to assume an indefinite amount of time prior to the Silurian. Of course it is impossible to say just . how long a time elapsed between the origin of life and the Silu- rian, but it seems hardly possible that it could have equaled the time since then. But upon evolutionary theories the animal kingdom must have developed during that period from the lowest unicellular condition to the complex and diverse fauna of the ‘Silurian. When we consider, therefore, that during this time all ~ of the important groups of the animal kingdom* arose, and that _ none have arisen since that time, it becomes quite evident that _ evolution must have progressed with greater rapidity at that time _ than it has since. This conclusion is no new one, for many nat- uralists have seen the necessity of making some such assumption. ; It will, indeed, be generally acknowledged that evolution at eaf- _ lier times was more rapid than at present. a ‘Now it follows as a direct result of this fact that the evolution a of organisms is approaching an end, and that it will eventually cease. If the rapidity of evolution as a whole has been decreas -ing since the beginning of life, it is evident that unless something __ *[It is very doubtful whether there were any Vertebrata during the Silurian —24-] 1886.] The Limits of Organic Evolution. 415 occurs to begin the process over again, evolution must eventually cease. This would lead us to the conception of the animal kingdom ds not unlimited in the extent of its development, but as having a definite end. This may be made clearer by two comparisons. First, consider the life of any individual. This begins with the fertilization of the ovum. Fertilization seems to endow the ovum with a large amount of vitality, or what has been called growth force. This growth force causes the ovum to begin to divide and grow with great rapidity, and the changes which take place as the result of this invigoration, are very great during the early part of the development. But immediately from the first the rapidity of this growth begins to decrease. As the individual -becomes older its rate of growth becomes less and less, the invig- orating force gradually expending itself, until finally a condition is reached where no further growth takes place. For some time à now the animal remains in a state of equilibrium, but finally begins to go down hill and dies. A better comparison still may — be found in the life of a tree. Here also we find at the outset a. rapid growth and advance, very early the rapidly growing stems give rise to buds which are to become the great branches of the - coming tree, and in a very short time the shape of the tree is determined by the growth. All of the larger branches have appeared, and they have already given rise to many of the smaller Ones. But here also the rate of growth diminishes, and as the tree becomes older and larger it grows less rapidly. Finally at a certain size its growth practically stops. It does not of course actually cease to grow. It is continually producing new leaves, _ new twigs; old branches are being in some places expanded, in others they are dying and disappearing. There is thus a constant — -change and growth taking place in the various parts, but the Srowth of the tree as a whole has ceased. For a long time, per- x haps the tree may remain in this condition, but little by little the Process of decay encroaches upon that of growth, and finally the : tree dies, ee . These examples are of course simple analogies, and it is a question how far they may be regarded as applying to the animal ingdom asa whole; but there are many facts which indicate rey the history of the organic world as a whole is parallel to the fe of the individual, in part at least. That the relations of ant- = $ : : j 416 The Limits of Organic Evolution. [May, mals in the world are to be looked upon as that expressed by a branching tree is now perfectly demonstrated. That all of the great branches of this tree, as well as many of the smaller ones, had made their appearance at the time of our first record of life, is also proved, That evolution since that time has consisted chiefly in the elaboration of these branches by increasing their division and the diversity of species and small groups, is becom- ing more and more evident. That there has been a slowing up of development in recent times is a fact which is strongly forcing itself upon naturalists; and the conclusion has found expression in the statements sometimes made that no new species are arising to-day, or that the present is a period of comparative rest. The same general principle is taught from embryology, for very early in their history do embryos become separated into the subking- doms to which they belong, while more and more slowly does the separation into the smaller groups take place, All of these facts together strongly indicate that the illustrations used above are in part real illustrations, and that the whole animal kingdom must be looked upon as an individual starting its history with a vigorous growth which is gradually expending itself. Whether or not this growth will reach a limit, and whether or not it will eventually cease so that the animal kingdom will disappear, it is our purpose to consider. That the organic world is approaching a limit to its develop- ment is a conclusion which does not depend upon any vague idea. of growth force for its support; for a little thought upon discov- ered laws will clearly show us that there must be a limit to advance. The best definition which has ever been given of the grade of structure of animals is the degree to which differentia- - tion of organs is carried. Evolution as it tends to raise the grade of animals is constantly increasing the amount of differentiation. A distinction must be made, however, between differentiation and specialization, Evolution sometimes results in retrogres- sion, and in these cases differentiation becomes less rather than greater. Evolution does not, therefore, always produce a gf eater differentiation, but in all cases, even in those of retrograde oe, development, it does produce a specialization of parts, and we _ may rightly regard evolution in the animal kingdom as a Pro cess of specialization. Now it is plain that this process ca” not go on forever, A low undifferentiated unspecialized organism 1886, | The Limits of Organic Evolution. 417 has an infinite possibility in its lines of specialization. A simple spherical mass of cells, the supposed common ancestor of the, animal kingdom, may be modified in a very great variety of direc- tions, each of which may give rise to a different type of animal. This possibility lies in the fact that it is as yet yndifferentiated and unspecialized. But just as soon as it does become modified in any one direction the possibilities decrease. Some of the de- scendants of this ancestor becoming vertebrates are forever pre- cluded from becoming anything else ; others becoming mollusks must remain mollusks forever, with all of their-descendants. And as later descendants become further modified in any direction into _ definite types, the chance for future modification, becomes rapidly less. It is only the absolutely undifferentiated which has infinite possibilities, for as soon as a single step is taken in any direction they become finite. Now it is. plain, since evolution does not retrace its steps, that with every step in advance the possible lines of development become less and less. All the descendants of the vertebrate line must conform to the vertebrate type. The verte- brate becomes separated into fish, reptile and mammal, and the individual of each group is still further fettered in its develop- ment by the special line which its ancestors have taken. e descendants of the animals which have started the order of birds can not take any new line. They can develop to perfection this type, but there they must stop. And so on, with every advanced . Step the possibilities of expansion are constantly decreasing.’ _ Now a continued specialization of this sort is sure to reach a limit eventually, it must run to extremes and then stop. Devel- opment must reach a position where further advance is no longer possible. Let us illustrate this principle by a concrete exam- ple. A five-toed appendage is an unspecialized form which we may conceive as modified in many directions. It may becomea = grasping organ or a supporting organ or a swimming organ, etc. — ; Be In the group to which our ruminants belong this appendage has become a supporting structure. In this same group there has : further been a tendency to rise upon the toes, in such a manner — - that instead of walking on the soles of the feet and palms of the -~ hands, the animals in question walk more and more upon the fingers and toes. When this peculiarity first began to manifes itself, the mammals had five toes. As it became more and mo: Pe This idea can be found fully expressed in the writings of Professor Cope- 418 The Limits of Organic Evolution, [ May, marked the shorter toes were little by little lifted from the ground and became of little or no use: In successive ages we find the shorter toes becoming smaller while the middle toe becomes larger. This line of specialization has continued until it has reached a limit. in the horse, which has lost all but one toe on each foot, and walks on the extreme tip of this toe. Now it is perfectly evident that a limit has been reached in this case. The horse may perhaps in the future lose the rudimentary splint bones which still remain, but he can not lose his last toe; and it is therefore impossible to conceive any further development of the _ horse in this direction. Now the same principle will apply to all other lines of specialization, although we may not always beable to see what this limit may be. Physical laws would of themselves set limits to every line of advance, even if there be no such limits determined by the organism itself. It is easy to find examples which will show that such has been the general history of groups in the past. Some have reached eee the extreme of their development in the distant past, and have ceased to advance or disappeared. Others seem even now to be at the summit of their advance, and others still are yet advancing. The line of development represented by the trilobites has com- ~ pletely exhausted itself. It rapidly approached its limits even in 5 the Silurian, and then began to dwindle away and has disappeared = Completely. The brachiopods had also at this time reached their _ point of highest specialization, and became a highly developed group even at this early age. Since then they have remaine -~ stationary as to their organization, having steadily decreased in ats numbers, and the few that are left show no advance over the Silu- = rian forms. The cephalopod mollusks gradually increased in complexity during the Paleozoic, and finally a limit of the shelled _ forms was reached in the ammonites of the Jurassic and Creta- = ceous. The culmination was followed by extinction. Meantime ~ a second line of development began, that of the naked cephalo- _ pods, and this has gone on advancing until the present time. The _ decapod Crustacea represent a group which is even now near its _ culmination. From their first appearance in the Carboniferous there has been a tendency toward concentration of organs toward the head. As this specialization advanced the abdomen became ‘smaller while the head region became larger. Finally in the crabs, which appeared in the Jurassic, everything was concen- ~ ih eee oe ae | Pig ev number of future subkingdoms, which would, of course, — ee the animal kingdom an example of never-ending evolution. — 1886. The Limits of Organic Evolution. 419 trated into the head region; the abdomen being little more than arudiment. Evidently we are here near a limit, and we may look upon the crabs of to-day as the culmination of the special line of development which has characterized this line of animals. The vertebrates in general have been continually advancing during geological times with a continued increase in specializa- tion and in multitude of types. But even here there has been the same story of limitation. The ganoids culminated in the Devonian, and have advanced no farther. One great line of rep- tiles reached its limit in the Jurassic. And so everywhere. The study of evety group teaches that the past history has been a gradual specialization, which approaches a limit. In many cases in the past this limit has been reached and advance ceases; while in others animals are still on their road toward it. It is plain, therefore, that the evolution of the whole animal kingdom is slowly but inevitably approaching an end. With every advance in differentiation the possible lines of development decrease, and since the actual lines followed are tending to run themselves out, the whole must eventually stop. Recognizing, then, that there must be a limit to advance, we must next ask the question, whether after this limit is reached the animal kingdom will become extinct ; whether, like an individual, it will die of old age? And here we must distinguish two ques- tions. First, is it not possible that animals which have remained Unspecialized during all times, should give rise constantly to new lines of development, and thus be a perpetual source of new for ms? Second, will the present groups, after reaching their cul- mination, become extinct or simply remain stationary ? That there is a theoretical possibility of the origin of new ~ types cannot be denied. New types, 7. e., new lines for specializa- — tion, can arise only from undifferentiated forms. But such undif- — ferentiated forms still exist in great numbers. Even the most = uNspecialized form of all, the unicellular animals, are abundant | enough, and in all groups we are acquainted with more or less generalized types, Theoretically, then, there is no reason why any of these forms should not expand itself and thus form an — ¢ternal source of new world forms. So long as the unspecialized forms do not become extinct, we cannot deny the possibility of 420 The Limits of Organic Evolution, [ May, But all of our evidence indicates that such a future is probably not a practical possibility, even though, as far as “we can see, it may be a theoretical one. All biological studies point strongly to the conclusion that instead of several points of origin the ani- ` mal kingdom has had only one. The subkingdoms have not arisen independently from the Protozoa, but have all had a com- mon ancestor, the gastrula, and this means that only once has the unicellular form given rise to important lines of multicellular descendants. Though the Ccelenterata stand very near this primitive unspecialized form, there is no evidence that it has the ; power of further differentiation ; but on the contrary, all tends to show that whatsoever differentiation of this simple type ever did take place, to give rise to the subkingdoms, occurred before the Silurian. Since palzeontology shows us that no new great types have arisen since the Silurian, it is plain that all of the expansion of the simple unicellular form must have taken place before the Silurian. And coming through the later ages we find evidence the same in its tenor. The conclusion everywhere seems to be that when a generalized form has given rise to one or two lines of f development, it either disappears or loses its power to originate new forms. Every step of palæontology carrying existing groups farther and farther back in the geological ages adds force to this general conclusion. Every bit of evidence which indicates 4 fundamental unity of the animal kingdom testifies to the same. Without questioning the theoretical possibility that any or all of ae the existing more or less unspecialized forms may in the future =. develop, we must acknowledge that the probability is against it. = Nothing in history indicates that these groups retain power to expand, and there is, therefore, no reason for thinking it a possi- bility in the future, Remembering what a large number of _. groups we are learning to trace back to the Silurian, remember- -~ ing that development has consisted, in the later geological ages, simply in the expansion of groups appearing long before, we must conclude that the power of the undifferentiated forms to expand into different lines of development disappears very early jn their history. While then we cannot deny the possibility of an indefinite future development from the existing generalize types, it is certainly improbable that any new great groups wi arise. Man, seizing upon the last undifferentiated faculty, the intellect, is developing this to extreme, and will probably be the last type to appear. 1886. ] The Limits of Organic Evolution. 421 The second question, concerning the probability of the various groups becoming extinct after reaching their culmination, is not so easy to answer. It is certainly possible to conceive of them as remaining stationary at their culmination, neither developing further nor becoming extinct. Undoubtedly the history of the past shows that after any group reaches an extreme of specializa- l tion it does not remain stationary, but begins to decrease in num- ; bers, finally to disappear. But the number of groups which have ; thus become extinct is not very great, and it is a question whether it is justifiable to claim that they really represent a general ten- i dency. It is certain that disturbing causes which have acted in ! the past to produce extinction will grow less and less in the future. We can see that extinction in the past has been due to: the inability of these extreme forms to adapt themselves to new circumstances with sufficient readiness. Of course when all of our present groups shall have developed themselves to extremes, they too will be unable to adapt themselves to new conditions, and would doubtless become extinct if they were called upon to meet adverse circumstances. But it is an acknowledged fact that physical changes are much less rapid now than they were for- merly, and that they are constantly diminishing. If this is the case the developed extremes of the future will not be called upon to meet such changes in condition as those which have induced extinction in the past; and they may even then be able to un- dergo such slight modifications as will enable them to meet the slight changes in condition. Moreover, in the past extinctions: have very generally occurred because animals have been unable to contend with the new and more vigorous forms which were capable of a more rapid modification than the older ones. But as we have seen, the number of possible new forms is constantly decreasing, and the time must come when it is no longer possible s new forms to arise to crowd the older ones out of existence. With almost stationary physical conditions, and with no new rivals, it may be that the animal kingdom is approaching a con- ; dition when, for reasons which we have seen, it cannot advance, and when there will be nothing to cause extinction, and it will © . therefore remain stationary. ae 4 There is one new condition, however, which is to have a pr ~ digious influence upon the evolution of the future. The influ- b aea ie ee _ Ace of man on the animal kingdom cannot be computed, but it = 422 = The Limits of Organic Evolution. [May, is probable that in many respects it will be a death blow to its evolution. Man is rapidly causing the extinction of almost all land animals, at least the larger ones. As the frontiers of civili- zation are being extended further and further into the uninhabited regions, he is driving out of existence all of the larger animals and many of the smaller ones. We have ,only to look ahead a comparatively short time to see the extinction of all land animals except such as man may preserve for his own use. To what ex- tent this may apply to other animals, to insects, marine animals, etc., is not clear. But in the highest group of animals, the verte- brates, it is pretty clear that man is eventually to bring about not only the end of advance, but also the practical extermination of all animals except such as he especially preserves. With all of these considerations together it seems perfectly plain that we must look upon the evolution of the animal kingdom as definitely limited and approaching an end. The tendency of spe- cialization to advance to extreme limits, the impossibility of the further adaptation of these extremes to new conditions, the sig- nificant fact that no new forms of importance have arisen during all the later geological ages, the great influence of man in causing extermination of all sorts of animals, all these point to the same end. Just as evolution began in time, so it will end in time, and we must look upon the animal kingdom as progressing toward a limit. When this limit is reached, either there will follow a grad- ual extinction through a diminution of vital power, or if this be not the result, a stationary condition will ensue in which such animals as man has left in existence will remain unmodified until the progress of physical changes makes this world no longer habitable. er a K a vied : $ $ ie # ; P 2 Ri 5 $ * Py a 2 at t 1886.] Ancient Rock Inscriptions in Eastern Dakota. 423 ANCIENT ROCK INSCRIPTIONS IN EASTERN DAKOTA. BY I. H. LEWIS. ta the celebrated map of I. N. Nicollet, of the “ Hydrographi- cal basin of the Upper Mississippi river,” published by the U. S. Government in 1845, appear, for the first time, two strange names in Eastern Dakota, not far from the sources of the Minne- sota river. The first is Wakiyan Hurpi (or thunder’s—not light- ning’s—nest), placed about thirteen miles north-west of the foot of Lake Travers; and the other is Wakiyan Oye, a few miles west of the head of the same lake. The route followed by Nicol- let, however, did not pass by either place, so he must have put them down from the general description of his guides, as he makes no mention of them in his text. It is of the latter locality, well known by its translated equivalent of “Thunder Bird’s Track ”—on account of the incised rocks there—that this article treats; together with another rock of like kind in the neigh- borhood. In the month of August, 1883, I was engaged in the survey of | the sepulchral tumuli, forts and other earth-works of Big Stone _ and Travers lakes, and thus being brought into the vicinity of the rocks in question, took the opportunity afforded of making care- ful traci much archeological interest. These tracings have been reduced by pantograph to one-eighth the size of the originals, and draw- ings thus made from them accompany this short account of the | “track rocks.” The first diagram shows the pictographs constituting “ Thun- der Bird’s Track,” as they are engraved on an irregular shaped Tock located some six miles west and a little north of the village of Brown’s Valley, Minnesota, and within the limits of the Sisse- = and Wahpeton reservation of Dakota Territory. The rock es on the summit of a hill which commands a good view of the Ountry, though there are other hills in the vicinity which have a ngs of the pictographs they showed, considering them of © ~ altitude. It is about three and a half feet in diameter,and : ~ there: S the first account I could find of it was in the shape ofa bi 424. Ancient Rock Inscriptions in Eastern Dakota. (May, resent human hands.

Are undoubtedly meant for hands, as their outlines can be imitated in shadow on the wall by placing one’s own hands in the proper positions. 7.

The other rock is known as “ Thunder Bird’s Track’s Brother ” —that is, a brother to the “track ”—and is situated about two miles east of his elder, on the slope of a terrace bordering the valley of the Minnesota river. As will be seen on comparison, the diagrams illustrating the two rocks are entirely distinct from each other in respect to the shapes of the characters, and by no means bear out the close relationship between the localities im- plied by the names the Indians have given them. The inscriptions on both rocks are apparently very ancient, and it is extremely doubtful whether the present Indians or their immediate predecessors (the Cheyennes ?) had anything to do with carving them. I made inquiry as to any traditions that might be current among the Dakota Indians on the reserve concerning these rocks, and obtained certain mythological information now concisely stated. ; = Thunder Bird is said to have had his nest on a high mound, which was composed of sticks and brush, and was situated some ten miles north-west of the foot of Lake Travers, in the cen- ter of a deep wide gorge. One day there was a great storm which flooded tlie whole country. Thunder Bird, in his anger at having been driven from his nest by the rising waters, flew away and alighted on this rock—Wakiyan Oye—which was the only place not covered by water, and left the impression of his feet On subsequently looking for printed records of this rae snort. poem from the pen of an Indian trader of 1823, W.

PENHALLOW. re amount of water which highly lignified plants contain, particularly as influenced by season and condition of growth, obviously bears a more or less important relation to physiological processes incident to growth, and most conspicuously to those which embrace the movement of sap. Studies relating to the mechanical movement of sap in early spring at once suggest the question as to how far this is correlated to greater hydration of the tissues at the time when this movement is strongest. It was with a view to exhibiting this relation more clearly, that deter- - minations of moisture in a large number of woods, representing -Ț growth of one and also of ten years, collected at different seasons, were made in 1874.) The range of seasons was not as complete as could have been desired, and no attempt was made to formu- late a general law applicable to this question. With a view to — extension of data in this direction, additional estimates were un- ray ken in 1882, and it is the object of the present paper to com- ine all the results thus obtained, together with such other fact 1 W. S. Clark. Agriculture of Massachusetts, p. 289. 426 Variation of Water in Trees and Shrubs, [May, as have come to our notice, and see how far they indicate a gen- eral law. Theoretical considerations lead us to infer that if there is any variation at all, the hydration of structure must be greatest during the period of active growth, and least during the period of rest. How far this is supported by the facts will appear in what follows. HYDRATION OF DEAD Woop. Incidentally to the main question, specimens of dead wood, deprived of the bark and representing an age of from four to eight years, were collected and the moisture determined. While the branches were dead, none of them were in an advanced state of decay, so that the contained water could not be regarded as that of active decomposition, but simply that which would be readily retained in the lifeless, air-dried substance as exposed on the tree. The results obtained from fifteen species of trees showed an extreme variation of 6.1. per cent, the range being from 12.9 per cent to 19.0 per cent of water. The mean hydra- tion obtained from these determinations was 15.1 per cent. The results appear in the following table : HYDRATION OF DEAD WOOD. Determined at 100° C. Oe a ae Species.

The specimens upon which the principal facts in this paper are - based, were collected as sections of living branches, representing on the one hand growth of two years, and on the other hand the growth of four years. For the obvious reason that the bark could not be properly separated from the wood with any degree of uniformity, it was left on in every case, so that in all the deter- minations here given the results show the combined percentage of water in wood and bark, Obviously this gives a result which differs materially from that which would be obtained if the wood and bark were considered separately. Also, while care was taken Not to collect specimens in which the dead bark was strongly developed, thus securing as great uniformity as possible, the very fact that the bark was present, as well as the certainty of its varia- bility in structural character, and thus also in hydration, as col- lected even from the same species at different seasons, rendered. certain variations in the results unavoidable. This will doubtless appear upon examination of specific cases, but error from this Source is reduced to a minimum in the aggregate, so that the mean results, in view of all the precautions taken, may doubtless be accepted as correct. From an examination of the following results it will appear that, comparing the young growth with the older wood, the per- centage of water is sometimes greater in one, sometimes greater in the other, conforming to structural peculiarities of the species | and the relative preponderance of more or less strongly hydrated tissue. The mean results, however, clearly show what we might infer upon theoretical grounds, viz., that in the youngest growth, as also in the sap wood, the percentage of water is higher by two - Per cent than in the older growth, where the heart wood is in relative excess. This is found to hold true in the mean results not only for each season but also for all seasons; in the former case, however, the disproportion showing a variation from 0.8 Per cent to 3.3 per cent, a PN oe 6'gt || SS, ofS Legh PS, gos |) Lob, Gbb [freee cece ee tome teeeneceecensesenen: a ales. oo eS || L£zv | gzv || ott | igh Get | SLY || Lh | Sov Suv wnuueyoses 330V ‘ ‘caoepurdeg 6'gz vitr S61 g' LE €-Li Se etn ee becsoneeneeeecasererr ess ** sry BUBIUISIB SHOIOUBSS) : ‘eaovUUILY YL vos vzs EzS v'6v L'Lv sesssresessneersesresseerentstettr ter] SUAPUVIS SUNSLJID *æ30814SV1IV : GLb || 6b | ogr vob | z'gb erate teeeereee oes Kesey ByBIPIOIWOA x9] ‘xau o'to || tzo | bol Log | 26S ; ’ teseees sees xor vrfojanbuinb sisdopduy tSt Lev g'gt o'gh Egt Lit Vey [[rccssce reeset ete Frees XYON BI[OJTPAOD SLA ‘LINA Eas Ers seia biari lage: ace ay ee ee es cy ” lit bof zib lit o'Sb Pe ee ` . rT vaqe snyy ‘waov|pavoruy EL ogr | gge met ++ tjsa snsopnpurys snpuvjty ‘warem : Eps 19S zs 6°SS g'gt- g'SS 6'£S rss ed se ee Sn ylang tala watts A 7 euvovowe VILL ‘æL Stt || £°6S OPS | “2S || gsi fen er A E, treset err vragidipny uoIpuapony g T æu eN } ‘avoh | 'IeəÁ ‘reah | ‘IgA ‘reak | 'IeaÁ savak | ‘eak tavok | ‘iea pz 451 pz s1 pz 4st pz qst pz 4st i ‘SUVINI N "4IQUIII AIPUAPS ‘zady y7427 “ALOR AGAT 3 Ey a k 1 r a A oS k 4 429 of Water in Trees and Shrubs.

As upon theoretical grounds the tissues contain most water when the growth is most active, data which will enable us to accurately fix the limiting periods for the season’s growth, will have an important bearing upon this question.

[ May, A graphic representation of these changes in connection with the curves of hydration, will enable us to determine the relation of growth and seasons to hydration of tissues: This comparison will show most conspicuously that that period at which growth for the season is chiefly terminated, is nearly coincident with the period of maximum tissue hydration, the former being but five or ten days later than the latter. From the foregoing facts the following appear to be the general laws: Ist, The hydration of woody plants is not constant for all sea- sons, and depends upon conditions of growth. 2d. The hydration reaches its maximum during the latter part of May or early June, and its minimum during the month of Jan- ‘uary. 3d. Hydration is greatest in the sap wood ; least in that which is older. 4th. Greatest hydration is directly correlated to most active growth of the plant; lignification and storage of starch and other products being correlated to diminishing hydration. These facts apply only to latitudes lying between New York - and Boston. For other latitudes, certain modifications might be necessary. :0: DOMESTICATION OF THE GRIZZLY BEAR. BY JOHN DEAN CATON, LL.D. E family of bears is among the most widely distributed groups of the quadrupeds, and is represented by a number of living species. They occupy the polar regions of the no and the temperate and torrid regions of both hemispheres. Som are of enormous strength and fierceness, others are diminutive o and comparatively mild in disposition. Nearly every species has = been held in captivity in considerable numbers, yet of their adap- ~ tability to domestication but little of real scientific value has been ~ Written, and I think I may add but little is known, for the want = of judicious experiment and careful observation. exhibited by street showmen, who have taught them various r ķ . . . . > i S me They are sometimes met with in the streets in various countries, amusing tricks, evincing considerable intelligence and docility, = : : 1886,] Domestication of the Grizzly Bear. 435 7 but these are generally of the smaller and milder species, and but little of their training or domestication has been recorded. Those which have been exhibited in gardens or menageries, as a general rule, are merely held in confinement, and not in domes- tication, so that little can be learned from them of their adapta- bility to complete subjection to human control. This can only be learned by long-continued experiments and observations under favorable circumstances by those whose tastes and inclinations. fit them for the task. My attention was called to this subject by reading the “Adven- tures of James C. Adams,” who was a celebrated hunter of Cali- fornia, who seems to have had a genius for capturing and domes- ticating wild animals. Among others he fairly domesticated quite a number of the grizzly bear (Ursus ferox Lewis and Clark) with complete success. This is the largest and fiercest known of all the species, and it might be expected the most intractable or unsub- missive to human control, yet such appears not to have been the case, The first specimens experimented with were two cubs, over a year old when caught, taken in Washington Territory, between Lewis and Clark’s fork of the Columbia. They were brother and sister; the latter was retained by Adams, and his experiments Were principally conducted on her, which he called “ Lady Wash- ington.” She seems to have been the more tractable and submis- sive. The male he parted with to a friend, after he had received but the rudiments of his education. At first they were chained to trees near the camp-fire, and resisted all attempts at familiarity and kindness; then severity was adopted, until they finally submitted. Soon after the male was parted with, and we have no account of his subsequent career, The female was always after treated 3 with the utmost kindness, and in a few months became as tracta- n: ble asa dog. She followed her master in his hunting excursions, fought for him with other grizzlies, and saved him from the greatest perils, a She slept at his feet around the camp-fire, and took the place ; Of a most vigilant watch-dog. He taught her to carry burdens a with the docility of a mule, and as she grew up her great strength oe enabled her to render him great assistance in this way- ee Another bear of the same species he captured in the Sierras se prd 7 436 Domestication of the Grizzly Bear. [May, California, before its eyes were open, and raised it on a grayhound - bitch in company with her own pup. This he called Ben Frank- lin, and proved more docile even than the first. He never found it necessary to confine in any way this specimen, but he was allowed to roam and hunt with his foster brother, the grayhound. They were inseparable companions, and seemed to have as much affection for each other as if they had been of the same species, Before he was full-grown, when his master was attacked by a wounded grizzly, he joined in the fight with such ferocity as to save his master’s life, and though he was severely wounded in this contest, with careful nursing he survived, and ever after showed as much courage in attacking his own species as if he had not met with this severe punishment. He seems to have had less confidence in Lady Wahia for she was generally kept chained during the night and when on the journey, though allowed to follow free when on the hunt. This may be explained by the fact that she was over a year old when captured, while the other never had any taste of wild life. i When she was chained up near the camp-fire in the Rocky mountains, she was visited several nights by a large wild bear, which her master refused to disturb, and she, in due time, bore a cub, which grew to maturity under the tuition of her owner, and which he called Fremont, which he says manifested considerable intelligence and sagacity, but not equal to that of his dam or to his favorite, Ben Franklin. It is to be regretted that exact dates are not given from which we can determine precisely the period of gestation, but by comparing all the dates that are given, it may be stated provisionally that that period was nine months. It has been stated by good authority that no instance has been known of any member of the bear family having bred in domes- tication, and this is the only instance where I have found such an event recorded or heard it stated. i Our author raised many of these animals, but generally dis- posed of them before they reached maturity, but he gives us nO particulars except in these two instances. He found the black bear, when raised in camp, as readily domesticated as the grizzly, andas fond of his society, following - him about the camp and through the woods with fidelity and attachment. 1886.] Domestication of the Grizzly Bear. 437 It is certainly interesting to observe how completely the savage nature of these ferocious animals was overcome in those which were born in a wild state, and it would be interesting to know what modifications might be made in succeeding generations by domestication, an experiment which could only be successfully tried under favorable conditions, which do not exist with the great number of animals of this genus now held in confinement. I may remark here a wide difference in the effect of domestica- tion upon the disposition of this animal and many others, which in the wild state show no ferocity, but only timidity. Take the Cervidæ, for instance, when brought up by hand; they lose all fear of man ; they develop a wickedness and ferocity never mani- fested in the wild state ; while the bears, so terrible when un- tamed, show docility, constancy and affection when brought into close familiarity with man. They seem to appreciate his kindness and care, and repay it with attachment and devotion, while the other class of animals, which are not ferocious by nature, seem to be entirely unappreciative of kindness, or at least seem incapa- ble of continued personal attachment to the hand that feeds them. When I first read Mr. Adams’ adventures, I considered it an interesting romance, or at least that it was largely embellished by an ingenious imagination, but upon inquiry in San Francisco, I met reliable persons, who had known him well, and had seen him passing through the streets of that city, followed by a troop of these monstrous grizzly bears unrestrained, which paid not the ` least attention to the yelping dogs and crowds of children which closely followed them, giving the most conclusive proof of the perfect docility of the animals. Indeed, they were so well trained that they obeyed implicitly their master’s every word or gesture in the midst of a crowded city, with surroundings which we might ‘Suppose would have aroused their native ferocity, if that were Possible, After the most careful investigation I became con- _ vinced of the reliability of the narrative, and as the facts our author gives are interesting to science, I venture to repeat them, — regretting, however, that he did not appreciate the great value of . his observati ons, since he might have given us more particulars which must have come under his observation ; but so it is that a : vast maiority of those who have good opportunities for observ- < ng do not know how to observe judiciously, or do not record _ r observations, 438 On the Nature and Origin of the [May, Mr. A. S. Kent, of San Rafael, California, who for many years, on account of his health, spent several months each year in camp life in the mountains, principally hunting the deer, informed me that he once purchased a couple of cubs of the grizzly bear, which he took into camp with him. One of these proved very docile and tractable, and seemed fond of his attention and society, and usually slept contentedly at his feet. The other seemed pos- sessed of a much more vicious disposition, and he was obliged to kill it. Possibly this might have been overcome by patient care and judicious training. There is no doubt that different dispositions among these ani- mals as among most other, may be met with. Mr. Kent’s observations tend, in some degree at least, to con- firm those of Mr. Adams. May we not hope that some one with the necessary taste and proper facilities will try experiments and give us the benefit of their observations ? A complete monograph of any one of our species of bears _ under all conditions would be a valuable addition to our zoologi- cal literature. —.0: ON THE NATURE AND ORIGIN OF THE SO-CALLED “SPIRAL THREAD” OF TRACHE#:. BY A, S. PACKARD. HILE we owe to Professor O. Biitschli the discovery of the mode of origin and morphology of the trachee, which as he has shewn? arise by invaginations of the ectoblast ; there being originally a single layer of epiblastic cells concerned in the forme tion of the trachee; we are indebted to Professor A. Weismann ae _ for the discovery of the mode of origin of the “intima,” from the . epiblastic layer of cells forming the primitive foundation of the =` tracheal structure. We are also indebted to Weismann for the discovery of the mode of origin of the terminal tracheal cells. Weismann did not observe the earliest steps in the process of formation of the stigma and main trunk of the trachee, which Biitschli afterwards clearly described and figured. Weismann, however, thus describes the mode of development 1870. 1 Zur Entwicklungsgeschichte der Biene, Zeit. wissen. Zoologie, XX, 51% = *Die Entwicklung der Dipteren im Ei. Zeit, wissen, Zoologie, X111, 1863- 1886.] so-called “Spiral Thread” of Trachee. 439 of the intima; after describing the cells destined to form the peri- toneal membrane, he says: “The lumen is filled with a clear fluid and already shows a definite border in a slight thickening of the cell-wall next to it. “Very soon this thickening forms a thin structureless intima, which passes as a delicate double line along the cells, and shows its dependence on the cells by a sort of adherence to the rounded sides of the cells (Taf. vu, 97 A, æ ó c). Throughout the mass, as the intima thickens, the cells lose their independence, their walls pressing together and coalescing, and soon the considerably enlarged hollow cylinder of the intima is surrounded by a homo- geneous layer of a tissue, whose origin from cells is recognized only by the regular position of the rounded nuclei (Taf. vit, fig. 97 B). “Then as soon as the wavy bands of the intima entirely dis- appear and it forms a straight cylindrical tube, a fine pale cross striation becomes noticeable (vir, 97, B, int), which forms the Well-known ‘ spiral thread,’ a structure which, as Leydig has shown, possesses no independence, but arises merely from a partial thickening of the originally homogeneous intima. “ Meyer’s idea that the spiral threads are fissures in the intima Produced by the entrance of air is disproved by the fact that the spiral threads are present long before the air enters. Hence the correctness of Leydig’s view, based on the histological structure _ Of the trachee, is confirmed by the embryological development, and the old idea of three membranes, which both Meyer and Milne-Edwards maintain, must be given up.” Weismann also contends that the elastic membrane bearing the spiral thread” is in no sense a primary membrane, not corre- sponding histologically to a cellular membrane. On the con- trary, the “ peritoneal membrane comprises the primary element of the trachea; it is nowhere absent, but envelops the smallest — branches as well as the largest trunks, only varying in thickness, u which in the embryo and the young larva of Musca stands in relation to the thickness of the lumen.” ~ „ Lhe trachea, then, consists primarily of an epithelial layer, the _ Peritoneal membrane” or the invaginated epiblast ; from this layer ` = intima is secreted, just as the skin or cuticle is secreted by the “ypodermis, We may call the peritoneal membrane the ecto- ~ Wachea, the intima or inner layer derived from the ~ ` ce i 440 On the Nature and Origin of the [May, the endotrachea; we hope to show that the so-called “ spiral thread” is not spiral in arrangement but simply thickenings of the endotracheal membrane, parallel to each other, not necessa- rily continuous nor arranged in a spiral manner. For these chitinous bands we would suggest the name żænidia (Greek, little bands). Our observations have been made on the larva of a species of Datana, which was placed in alcohol, just before pupation, when the larva was in a semi-pupal condition, and the larval skin could be readily stripped off. At this time the ectotrachea of the larva had undergone histolysis, nothing remaining but the molted en- dotrachea, represented by the tænidia, which lay loosely within the cavity of the trachea. The ectotrachea or peritoneal mem- brane of the pupa was meanwhile in process of formation; the nuclear origin of the tenidia was very apparent, and it was their appearance which led me to examine the origin and mode of development of the so-called “ spiral thread,” and to endeavor to trace its relations to the intima (endotrachea) and peritoneal mem- brane (ectotrachea). z Fig. 1 is a longitudinal section through a secondary tracheal branch, showing the origin of the circular chitinous bands, or tænidia. At 7 are pieces 0 six tænidia which have been molted; ecir are the nuclei forming the outer cellular layer, the ectotrachea or pen- toneal membrane» Fic. 1.—Longitudinal section of a trachea, showing i send the origin of the teenidia or so-called spiral thread. € These nuda long slender p!” longations around the inside of the peritoneal membrane; these . ;prolongations, as may be seen by the figure, become the tenmi.

The middle portion of the tenidia, immediately after the molt, is clear and transparent, with obscure minute granules, while the nuclear base of the cell is filled as usual with abundant granules, and contain a distinct nu- cleolus. The origin of the tenidia is also well shown by Fig. 2, which is likewise a longitud- inal section of a + trachea at the point of origin of a branch. The peritracheal membrane or ecto- trachea (ectr) is com- posed of large granu- lated nuclei; and within are the more t transparent endotrach- eal cells; at 7 are fragments of the molt- ed tenidia. The new tænidia are in process of development at t; at base they are seen to be granulated nuclei, with often a dis- tinct nucleolus, and sending a long slender, transparent, pointed Process along the inside of the trachea. These unite to form the chitinous bands or so-called spiral threads. The tenidia I have found to be separate, independent, solid rings, More or less parallel and independent of each other. The Supposed spiral arrangement I believe to be an optical illusion. The tænidia of a main branch stop at the origin of the smaller branches, and a new set begin at the origin of each branch. This fact also shows conclusively that the chitinous bands are not Spiral. Nor do the tenidia at the origin of the branch pass en- trely around the inside of the peritoneal membrane; in the axils Gs y are short, separate, spindle-shaped bands. -o The tænidia are usually thin, flat, but often slightly concavo- : sf a convex, the hollow looking towards the center of the trachea.

Macloskie.! It seems to me that the function of the tenidia is like that of the cartilaginous rings of the trachez of vertebrates, 7. e, to keep the air-passage open so that the air may pass to the cells at the end of the trachea. All the figures of the spiral thread hitherto published I believe to be incorrect. In Guyon’s work on Pulex penetrans they are repre- sented to form a loose spiral, and so they appear at first glance under a low power in the trachez of the common flea of the cat. But on close examination, in an excellent preparation, the so-called spiral thread is a series of independent parailel tænidia, the spaces between them being wider than usual. In Fig. 3, from a prepa- Fic. 3.—Stigma and trachea of Pulex, ration kindly presented to me by Mr. Justin Spaulding, æ repre- sents one of the first abdominal spiracles and the trachea arising from it; 4 the fifth; and c one of the last abdominal spiracles and its trachea. When the trachea bends or contracts in diameter the taenidia become less parallel, and a spiral appearance is produced. In the last pair the tænidia are remote from each other. In a preparation of one set of the salivary glands from the head of the honey bee, given me by Mr. Spaulding, the common duct is much like a trachea, having similar tenidia, and here they are observed to be parallel, independent bands. The sections of Datana were made for me by Professor H. C. -Bumpus of Olivet College. 1 Thus far I find myself unable to agree with Professor G. Macloskie that = tort the teenidia are really tubular. In his valuable and suggestive article, “ The Struc- ture of the Trachez of Insects (AMER. NAT., XVII, 567), I believe he has demo - views and figures I believe, in the main, to be correct, but thus far I am unable to convince myself that the “ external fissure ” of the tenidia in the figure he copies from Chun, whose original essay I possess, is really such ; it appears to be a new _ tenidium in process of formation previous to molting. 1886.] . Editors Table. 443 EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. In our issue of June of last year we referred to certain conditions of membership of the National Academy of Sciences in the following terms: “In the interval between the annual meetings of 1884 and ’85 two members of a committee appointed to investigate a question affecting one of the bureaus of which they themselves are employees, were requested to resign from the committee by the chief of the bureau in question. This was in obedience to a rule that a department of the Government can not be criticized by its subordinates. It requires no argument to show that if this rule be carried out with reference to the Academy of Sciences, its usefulness as an independent body is at. anend. There is also another danger which flows directly from the same or a similar attitude on the part of heads of bureaus, These gentlemen by filling up the academy with their employees can obtain practical control of its decisions. This would be im- mensely convenient to them under various circumstances, but it would introduce an element of corruption into the academy from which it has been hitherto happily free, and which would deprive > it of the respect and confidence of the country.” ; In the case first cited the bureau’s action would indicate an apprehension of hostile criticism, perhaps judging from the char- `- acters of its employees who had been appointed to investigate. In the latter case reference was made to a case where the bureau 3 concerned did not ask its employees to resign, since it evidently did not fear any adverse report as a result of their investigation. In this case some of the members of the committee appointed by — the president of the academy to coGperate with the committee of Congress in the investigation of the scientific bureaus, were em- ployed by some of the bureaus at high salaries.

That is, they are appointed - in the interval of the academy’s meetings by the president alone, and make their reports without the supervision or criticism of the kd 444 Recent Literature. - [May, academy, which only hears of them at the next meeting as a mat- ter of history!

The precious man- uscript became the property of the late Abbé Brasseur, and with - his collection finally passed into the hands of Mr. Alphonse L. inart, who loaned it to Dr. Brinton for publication. Assisted by natives the learned Abbé had made a tentative French transla- tion of the document, and in perfecting it he was materially aided by the then extant Spanish translations of some select por- tons. The document is authentic and of high ethnographic value. Let us now examine how Dr. Brinton has acquitted him- ‘Self of the task of editing, translating and commenting it. cokhe missionary, F, de la Parra, who died in 1560, introduced into the Cakchiquel alphabet five un-Spanish letters or signs to represent certain “cut” sounds! of that dialect.

Cakchiquel never became a literary language in our sense of the term, and consequently its orthography was never regulated by anything like steady principles. In the “ Annals” the ortho- graphy is about as unsettled as can be. Now in editing texts of this description, the first thing to do is to adopt scientific princi- = ples deduced from and consistent with the character of the lan- guage; to introduce a correct, logical punctuation, to separate the prefixed pronouns from their verbs or nouns, ¿if separable, to make compound words conspicuous as such aż sight, and to unite the tense and modal signs with the verb into one word. On the lower margin the editor has to indicate all the readings of the orig- E7 inal for which he introduces emendations, according to his system, into the text. Of a similar proceeding Brinton has no conception whatever, for he reproduces the most flagrant incongruenties, which every school-boy might easily correct, in his text, Thus he as writes: qui bi, and in other places quibi, keir names (p. 66), chu a kahibal and chukahibal, aż the setting (p. 68), Iximche and Yxim- a chee (name of the capital, with the old-fashioned Spanish y for =. Š p. 166), qari instead of qa ri, and they (p. 68), and many other Ac instances sufficient to perplex the student. Besides this, Brinton TR as also “ doctored” the manuscript by introducing text-readings oi. of his own, for in the introduction (p.63) he says: “ I felt myself free _- toexercise in the printed page nearly the same freedom which I fin in the manuscript.” He did so, undoubtedly, not only in the In- È dian text, but also in French quotations from Brasseur, in which - he shows himself fearfully at variance with the accepted French o accentuation : p. 197, and still more on p. 206. On p. 206 the term 7euvre is twice written 7euvre. Neither has the proof-read- ing been thoroughly attended to; p. 168 we find Yaxontik, and in the translation Yaxonkik; p. 107, Vookaok, a proper name, which is spelt voo kaok on p. 110; p. 66, mahaniok, defore ; in the vocabulary the same term is spelt mahanick. Bes r all this we are not much surprised at the punctuation 0 ~ the Indian text, for where there is, and ought to be, a period in the - translation, Brinton often has a comma or nothing at all in the text. On p. 66 paragraph third is subdivided into 1, 1, 0, where study Brinton’s “system” of editing and, as he calls it, his “ freedom ` in the printed page,” as it does to acquire the whole of the Cak- _ chiquel language, which cannot by any means be called a very difficult one. 195-208.

On. pp. 176, 177 he omits in the translation the whole sentence: fo «bokotah chiqa el Qeche vinak ($ 145), because he could not. find in his dictionaries the original form of the verb xbokotah. Like- wise are omitted from the translation opposite the words rahpop ` achi Ig'ich, and the counselor lg‘tch. No gap or empty space was left in the translation to remind the reader of an omission, as fairness would have prompted every common-sense editor to do; neither do Brinton’s “ Notes” give notice of any omission havin been made consciously. Students confiding zz the translation alone might thus get cheated out of very important facts stated in the Indian original. It would be interesting to find out whether Brinton made any such “ omissions ” from the original also; in that case passages would be left out in the text as well as in the translation. . “n comparing the small compass of the vocabulary contained in pp. 209-227 with the bulky text, which holds not less than Sixty pages, our curiosity becomes aroused to some degree. For how could the large number of terms composing the texts become enclosed within so small limits, although there is a sepa- rate index for proper names? Further examination easily reveals the fact, that vuo-o, voo, five,a numeral often occurring in the text, is mot in the vocabulary; ahauh, rwer, is there, but the verb Ae: ło rule, of which xahauar (p. 87) is a conjugational form, is not i there; we fail to find there: petebal, navipe, onohel, g‘anel (the name of ‘a month) of the text; for fa the definition from is omit- ted, though referred to in the “ Notes.” Tok is probably the same as tak, though we get no information on this point; g‘ana (p. 68), though translated by glorious, is not recorded.

He states (Zur Ethnographie Guatemalas, p. 139), that Cakchiquel possesses three tenses only, and that the three or four others given by the Spanish missionaries do not exist, but were “squeezed out” of the natives by the application of Latin models. The verb lok‘ (p. 146) which supplied para- digms to the unfortunate grammatic attempts of the Padres to conjugate amare, to love, does not signify żo Jove at all, but fo pur- chase. The verb to prize, to hold dear, to esteem, is not, as falsely quoted by Brinton (p. 216), lok‘, but lok‘oj (Stoll, p. 147). Or did the language change as much as that within the last two hun- dred years? à In the Introduction, p. ọ, the editor states that the three Maya 7 nations more closely related to the Cakchiquels: the Quichés, the Tzutuhils and the Akahals “ dwelt respectively to the west, the south and the east of the Cakchiquels.” Had he looked up the matter in Stoll’s map and in the map of the Grammar published by himself, he would have noticed that the Kichés lived, and still live, upon a much larger territorial extent, north, west and partly south of the Cakchiquels, and that the Tzutuhils are ‘en- closed on all except the western side by Cakchiquel settlements. a In the long list above, the mistakes and shortcomings were quoted from a few pages of the book only, and readers may decide for themselves how numerous the errors may be for the other nineteen twentieths of the volume.

Dealing as it does with the soil, the atmosphere, plants and animals, one would Suppose that careful and expensive experiments would invariably be confided to men trained in one or more of the great modern “ sciences—chemistry, physics, botany, zoology, geology, meteor- ology. That such has, however, not been the case, is shown by an examination of the reports which have appeared with more or less regularity ever since the agricultural colleges and agricultu- ral departments of the State universities were organized. With here and there an exception, such reports have contained nothing which were of any value to a scientific investigator in any field whatsoever. The report of the New York Agricultural Experiment Station for the year 1885 is noteworthy in several ways, not the least important of which is its early appearance, the copy under review having reached us early in February. Its contents are full of val- uable matter covering nearly the whole field of agriculture in its Widest sense, We can take time here for but a hasty glance at a few of the more important topics. The results of duplicate plantings (p. 37) are suggestive. In the case of Indian corn differences in yields equivalent to from two to fourteen and fifteen bushels per acre were obtained from similar plats treated in the same way. Of similar significance are many of the duplicate germinations of seeds (p. 54). In the germination of seeds to determine the influence of age (p. 58), much greater quantities were taken than is customary, the usual number here being some hundreds, often reaching several etait Results obtained in this way are much more satis- actory. e same precautions enter into the temperature exper- - ments upon germinations of Indian corn (p. 64), and in the latter case some very useful results have already been reached. .

Nicholson, in his monograph of the British Stromatoporoids, frankly accepts the views of Carter, Lindstrom, Zittel and others as to their coelen- terate affinities, and regards them as a special group of the Hy- drozoa, having on the one hand relationships with Hydractinia, on the other with Millepora. The skeleton of the typical Stromato- poræ is penetrated by numerous minute flexures, but essentially parallel vertical tubes, not bounded by distinct walls, but enclosed by the vermiculate fibers of the ccenosteum, precisely like the zooidal tubes in Millepora: These tubes are traversed at intervals by calcareous plates. A detailed comparison between Hydrac- tonia echinata Flem., and forms of Actinostroma Nich., shows 4 remarkable similarity between the chitinous skeleton of the first and the large calcareous coenosteum of the second. Our author arranges the group in four families, two of which, Actinostrom' dz and Labechiidze, are Hydractinoid, while the Stromatopor and Idiostromide may be regarded as Milleporoid. The last family contains genera which have a central, axial, tabulated tube aoe proper wall, giving off lateral branches, which ivide, Fossıt Hiprororami.—Dr. Henry Woodward, in a review of os _ the species of Hippopotamus, shows that at least two species (H. identical W! - 1886, ] Mineralogy and Petrography. - 453 is by Mr. Woodward (agreeing with Professor Boyd Dawkins) considered to be identical with Æ. minutus from the caves and fissures of Malta.

Exactly the same difference is observable in fungi, substituting only glycogen for starch or inulin. The great reservoirs of food- material in fungi are the sclerotia. The sclerotia of Claviceps purpurea contain oil, those of Coprinus niveus, Peziza sclero- tiorum, &c., glycogen, while in other cases the food-material is accumulated, as in some seeds, in the form of thickenings of the cellulose-walls. fructification is subsequently formed.

George Henslow read a paper before the Linnean Society entitled, “A contribution to the study of the relative effects of different parts of the solar spectrum on e transpiration of plants,” which is of such interest that we reproduce its more essential parts.

[May, transpiration per se (theoretically distinct from the purely physi- cal process of evaporation, which takes place from all moist sur- faces and bodies, dead or alive) is especially, if not solely refera- ble to those particular bands of light which are absorbed by chlorophyll, and that such light, being arrested, is converted into heat, which then raises the temperature within the tissues and causes the loss of water. The only additional fact which I have here advanced, somewhat tentatively, is, that yellow light hasa retarding influence upon transpiration, for the reasons given above. That ‘life’ has a retarding influence upon evaporation as distinct from transpiration, I think my experiments (which I hope to continue hereafter) have distinctly proved.” It will puzzle any one to make out a good reason for using two terms for the process of water-loss in plants. We have it said that “ evaporation” is the “ purely physical process,” while the experiments show that what is called “transpiration ” is, after all, a physical process also; and when we are told, as in the last sen- tence above, that “ life has a retarding effect on evaporation,” the confusion of ideas becomes somewhat embarrassing. : use but one term, and that the more general one—evaporation?

Í DEVELOPMENT OF THE MoLE CRICKET.—A. Korotneff has pub- lished in the Zeitschrift für wissen. Zoologie, XLI, 4, 570, a well ! illustrated essay on the embryology of the mole cricket, which as been also noticed by C. Emery in the Biologisches Central- blatt for Jan. 15, in connection with Grassi’s observations on the i development of the honey bee. The egg of the mole cricket has an abundant yolk, while that of the bee has little yolk and is small and transparent. Yet both observers have independently arrived at the same results in four important points. It is note- worthy that in both forms before the formation of the blastoderm a stage was observed in which ‚the amceboid embryonal cells seemed to possess no clear nuclei. With this result might connected the relation briefly described by A. Sommer in the case of a Podurid, when the ripe egg was entirely without a nucleus. Whether there was in all these cases a genuine absence of the : nucleus, or a diffuse nucleus form, such as Graber discovered in ae the Protozoa, is still to be determined, and would not be without interest in connection with the late reflections of Weismann and . others on heredity. ? In Gryllotalpa the embryonic cells are at first scattered over the surface of the egg; some migrating into the deeper parts of the yolk and forming the yolk cells regarded by Korotneff as the primary mesoderm. From the ectoderm exclusively separates the endoderm. There first originate, under the ectoderm cells which Korotneff denotes as mesenchym, and not till later does the separation of the myoblasts follow along the ventral median oe line. Later still arise from the ectoderm near the trachee other = — groups of cells which are also to be considered as mesenchym, o and which were also observed in Bombyx by Tichomiroff. mbryonal membranes serosa and amnion arise as ecto- dermal folds.

The cells of the primary ento- derm (the yolk cells) undergo a radial division of the yolk, the ' yolk-pyramids thus arising melting into each other centrally. Some of the cells grow and form, under the serous membrane which has not yet disappeared, the dorsal wall of the body, and the dorsal plate or dorsal organ. Through the growth of the parts forming the lateral walls of the body, the dorsal organ gradually becomes covered, its cells sink into the yolk and seem to break into fragments. After the ectodermal parts of the diges- | tive canal (fore and hind intestine) have formed, amceboid cells still migrate into the yolk, and seem to contribute to its fluidity (verflussigung). After hatching, the whole yolk by a pumping movement, gradually becomes, including whatever is contained in the same, partly degenerate cells, thus pushing the so-called pri- mary entoderm into the portion of the fore-intestine, called the crop. The mesenteron receives no epithelial covering from the Primary entoderm, and the epithelium of the mid-intestine, almost everywhere between the yolk and mesoderm; the heart becomes indicated in the form of two furrows, which draw near. _ blood-lacuna which covers the dorsal side of the yolk and be- comes reduced to the cavity of the heart.

The yolk cells thereupon disappear ; according to Grassi the figures quoted from Tichomiroff as well as from O. and P. Hertwig, in regard to the proof of the origin of the endoderm in the yolk cells can also be explained to agree with his views. The amnion and serous mem- branes are not separated in the bee, but form a single layer of cells. Grassi is inclined to trace the embryonal ‘membranes of insects phylogenetically from an especially modified dermal fold, which was inherited from the ancestors of the class; such a duplicature, suggests Emery, might be comparable to the mantle of many Entomostraca. According to Grassi the cerebral ganglia arise independently of the ventral chain, and is afterwards connected with it. The entire nervous system and, as far as could be observed, also the commissures arise directly from the ectoderm. The antennz are developed from the head plate (procephalic lobes) and are situated in front of the other appendages. A pair of cephalic appendages Previously observed by Biitschli, which only appear for a short time in front of the mandibles, soon disappear. Grassi considers ` them as homologous to the second antennz of Crustacea. e found abdominal appendages only exceptionally, and not on all the segments. The observations of Grassi on the mode of devel- , opment of the heart agree well with those of Korotneff on Gryl- lotalpa ; both uphold the hypothesis of Biitschli of the origin of i the vascular system from the residue of the segmentation-cavity, ` ’. ê, the primitive body-cavity. The sexual organs originate as two mesodermal elongated streaks in the 4th-8th abdominal segments.

If one accepts the fact that the trachez and the malpighian tubes have originated from diffusely distributed cutaneous glands, then one could further suppose that their openings unite later with the openings of the nephridia, by which means they assumed a segmental arrangement. But, however, it is not at all neces- sary to make the nephridia arise from the ectoderm, which would contradict all the researches hitherto made.

ZOOLOGY. MARKINGS or Antmats.—Eimer has advanced the view that the markings on animals are primitively longitudinal stripes, r ontogeny of many animals. Dr. W. Haacke controverts this view from the study of an Australian fish, Welotes scotus. The adult fish is marked by eight longitudinal black bands; young specimens have in addition a row of clear transverse bands, which disappear when the fish attains to maturity.— Journ. Roy. Mier.

The place is celebrated for the occurrence of these shoals, which for the most part con- sist of small fishes, and are composed of several distinct species. he shoals are most common from May to November, during the rainy season, but in fine weather, when there is a moderate breeze from the sea. Sharks and other predatory fishes, as well as whales and sea-gulls, follow the shoal. The movement of the fishes is probably due to migration in search of food, the conforma- - tion of the coast at Carupano is such as to favor the embayment of the shoals at that point, and the death of the fishes is. caused by submarine eruptions of gases. — T.

ON THE SYMMETRY OF THE FIRST SEGMENTATION FuRROWS OF ‘THE Biasropisk oF ELASMOBRANCHII.—The nearly symmetrical subdivision of the blastodisk of Teleosts by the first four seg- mentation furrows has long been known. The details of the es carefully elaborated by Agassiz and Whitman,’ whose conclu- some sions are, I believe, generally accepted by embryologists. Of the X development of the blastodisk of Elasmobranchs we know com- paratively little, especially in relation to the relative lee and =~ direction of the first segmentation furrows. The object of the S present note will therefore be to describe the early segmentation of the blastodisk of one of the latter, viz., Rata erinacea, as dis- played by an egg removed from the oviduct and cloaca of a _ female of that species, July 11, 1885, at Wood’s Holl, Mass. , Upon opening the tough horny membranous envelope in which the ovum proper of Raia is enclosed; it is found that the egg § somewhat pinkish in color, and is imbedded in a layer of very - glairy “ white ” or albumen, which fills up the space between the egg and the horny case. The pinkish egg proper is somewhat flattened and oval in shape, and is immediately invested by a very thin and delicate vitelline membrane. At one side of the flattened vitellus, which measures nearly one and a quarter inches through its longest diameter, a small circular whitish area about two mit- _ limeters in diameter is noticeable. This is the blastodisk or get minal area of authors, and is the point where development first egins to manifest itself. d = H the egg case is carefully opened, the white removed an _ then laid into a one per cent solution of chromic acid, the blasto- _ 1Edited by JoHN A.

Such was the treatment to which the blastodisk here figured and described was subjected. The surface view, Fig. 1, was drawn with the camera lucida after hardening, and the section shown in Fig. 2 was drawn from one taken at about the position of the line ain Fig. 1. Cleavage had already advanced so far as to subdi- vide the area of the blastodisk into fifteen sharply defined cells, So that it may be assumed that this blastodisk has nearly com- pleted its sixteen-celled stage of development or that the fourth cleavage is about completed. _A comparison of the first four cleavage planes of this blasto- disk shows that they are formed in very nearly the same order and relation to each other in Elasmobranchs as in Teleosts. For example, the first plane 1, in Fig. 1, has cut through the originally circular blastodisk and caused it to become elongated at right angles to the direction of the first segmentation furrow exactly as in the eggs of teleostean fishes. The second furrow, II, cuts the first at right angles so as to further subdivide the first two cells into four. The next cleavage is caused by two nearly par- allel furrows, III, 111, which appear simultaneously, and further subdivide the cells of the blas- todisk into eight. The fourth cleavage i -celled stage of teleostean d it is also evident 472 General Notes. _ [May, velupment of the eggs of the Elasmobranchs. The subdivision of the blastodisk into cells in both types of Ichthyes is essentially a symmetrical one, determined by the first cleavage plane. Whether or not the first cleavage plane of the ovum of elasmo- branchs coincides with the median plane of the future embryo, as supposed by Whitman, Roux, Pflüger and E. Van Beneden, it is impossible to decide at present, but it would seem not at al _ improbable that such might be the case. series of sections of this blastodisk of Raia, prepared by the aid of a Cambridge rocking microtome, which was presented to the U. S. Fish Commission by Professor Adam Sedgwick, have enabled me to reach some interesting conclusions in reference to the structure of the blastoderm of the Elasmobranchii during its one-layered condition. At this stage the four median or central cells are not completely sundered from the underlying periblast, P, Fig. 2, since the cleavage furrows are found to terminate ab- -ruptly. before they have quite cut through the finely granular plasma of the blastodisk proper, as shown in Fig. 2. In this respect the cleavage of the blastodisk of Elasmobranchs differs very decidedly from that of teleosts as described by Agassiz and ~ ot a et ch be a m i mh 5 aR < E jasi 3 oS — w m je — i nn z, iss) © s or -R oO wn m wq z oO =) T, =] vq oR ice) un of nm ° z Nn og =, which lies a discoidal mass of coarsely granular yolk, Y.

It is indeed far more likely that they originate by a process of segmentation in which the marginal cells of the blastodisk are involved the same as in Teleosts. Such a view is in fact supported by fig. 15 given in Balfour's Comparative Embryology, Vol. 11, p. 34, in which two free nuclear spindles are shown at the edge of the deeper- lying part of the blastodisk of Pristiurus in the morula condition, consisting of four superimposed rows of cells. Balfour’s figure also shows that between the lowermost cells composing the blas- todisk and the coarsely granular vitellus there is still a consider- able unsegmented stratum of finely granular plasma interposed. In this lower layer of finely granular plasma alone the “ free nuclei” are found, thus furnishing additional evidence that the view expressed above as to the origin of such nuclei is probably correct. In the disk of Raia examined by me, the cleavage planes are also marked by the clear margins of adjacent cells, as in the blastodisk of Pristiurus figured by Balfour. The blasto- disk of Raia here figured and described measured 1.71 millime- ters in width and 2.37 millimeters in length. Its thickness in the center was about .6 of a millimeter, and thinned out at the mar- Sın into a very thin layer of plasma which is obviously homolo- gous with the cortical or periblastic layer of the teléostean egg. ter stages of the blastodisk of Raia show it subdivided into smaller and more irregular cellular areas; the whole disk also again assumes much more nearly the original discoidal form characteristic of it previous to the beginning of segmentation. To Judge from the condition of the blastodisk here described, it of course is to be inferred that the fertilization of the egg takes Place while it is still in the oviduct, or possibly even before it en- ters the latter —Yohn A.

In the same paper I state that waste tis- sues being albuminoid are undoubtedly eliminated in the same way, i. e., by splitting in the liver into a carbo-hydrate which is burned and an incombustible nitrogenous residue to be eliminated mostly by the kidneys. The researches of Schiff? demonstrate that waste tissue undergo some important, yea necessary, change in the liver, but as to the nature of the change he says nothing. If the disposal of waste is connected with sugar making, as I affirm, this fact entirely explains the continuity of the function. Again Professor Seegen says: “ The formation of peptones (at least in carnivores not growing) is mostly to form sugar.” I say, “The whole albuminoid-excess is split into sugar to be burned for vital force and vital heat and an incombustible residue to be otherwise eliminated, 2. e., the whole albuminoid-excess 1s utilized as sugar.” i As to the experiments of Professor Seegen and others soa that with carbo-hydrate diet the sugar in the portal vein Is tess than in hepatic vein, I confess they are wholly unintelligible ye me.

OR a period of many millions of years—how many not even Conjecture can decide—the world of vertebrate life continued quadrupedal, the seeming deviations therefrom being rather appa- rent than real. Suddenly a true biped appeared. Fora period of equal duration the mentality of animals developed with exces- sive slowness. Suddenly a highly intellectual animal appeared. The coming of man indicated, both physically and mentally, an extraordinary deviation from the established course of organic development. Both physically and mentally, evolution seems to have taken an enormous leap, instead of proceeding by its usual minute steps; and in the advent of the human species we have a mmarkable problem, whose solution is as difficult as iti joe . portant. : It might be solved in a moment were we able to accept the eS arguments of those who hold that man is the outcome of a dis- _ ere tinct act of creation, and is invested with powers and qualities, > and prepared for a destiny, in which from the beginning he has Stood apart from all other living beings.

This realm is not 4 aoa ted kate 494 | "The Making of Man. [June, has sprung, and into which he is so deeply rooted that not the hand of a god could tear him loose. It is not our purpose here to give any of the arguments in favor of this conclusion. They may be found fully presented elsewhere. We design rather to endeavor to trace the line of ascent of man from the lower animal world, and to seek to dis- cover to what combination of highly favorable circumstances his development is due, Physically man does not deviate very greatly from the mam- mals next below him. His method of locomotion is essentially changed, but structurally he is very closely related to the higher - apes. Yet so much are all living beings the creatures of circum- a stance, that it seems possible, and even probable, that the remark- able mental differentiation of man may be a necessary result of d this comparatively slight physical differentiation. His erect atti- | tude, with certain variations in his life-habits which directly arise from it, bring him into new relations with surrounding nature, and these new relations have certainly very much to do with the new conditions which have arisen within him. A single step may lead at times to a vast train of unexpected consequences, and such seems to have been the case with this new step in evolution made by man. sal Man is the only true biped. He has but two points of support, while all other animals are supported at four or more speciali i : points, or else rest on the general surface of the body. In birds, A for instance, which are usually considered bipeds, the wings are _ organs for aérial support, and have no other function. The near est approach to man in this respect, among existing animals, may be found in the forms which progress by jumping, such as the kangaroo. Yet in these the structure and function of the fore limbs is distinctly locomotive. And such was probably the case _ with the dinosaurian reptiles of a past geological era, despite the ; fact that they seem to have been able to walk, to some extent, 0? their hind limbs alone. . E re Ri certainly remarkable that, in the whole extended period of a = animal life, no single vertebrate form appeared, so far as we can _ discover, before the advent of man, in which the fore limbs were : re completely freed from duty as organs of support and became structurally unfit for this duty. A partial freedom in this ae would be of minor value, since the formation necessary tO loge $ $ p 1886.) The Making of Man. 495 motive duty must be retained, and the development of any new functional power would be checked. Thus in this respect man is 4 an anomaly in the kingdom of life. And to this anomalous fea- : ture is quite probably due in very considerable measure the pecu- liar character of his development. z It is very evident, indeed, that the full adoption of the erect ; attitude gave man an immense motor supremacy over the lower animals; for it completely released his fore limbs from duty as organs of support—for the first time in the known history of ver- 4 tebrate life. They were set free to be employed in new methods T and to develop new functional „powers, to which the grasping ris function, which man inherits from the ape tribe, was an invaluable aid. It is to the possession of two limbs which are freed from any organic duty other than attack and defense, and which are adapted to grasp weapons and tools, that man owes his enormous advantage over the lower animals. - It opens to him possibilities : which do not exist beneath him, All the forces of nature are at ne his command, as soon as he can learn to control them. The first : club or Spear he grasped, the first missile he threw, inaugurated a new era in the history of life, and opened the way to man’s complete mastery. And, so far as we can perceive, this important | structural advantage preceded the development of his mental : Superiority, and gave the cue to it. ; In the vertebrate class below man, there exists but a single ani- 4 mal form that possesses a limb which is free from duty as an — Ey organ of support. This is the elephant, whose nose and upper - we lip have developed into an enormous and highly flexible trunk, 4 with delicate grasping powers. The possession of such an organ : has undoubtedly had its share in the marked intellectual develop- _ ment of the elephant. Yet this organ is far inferior in its powers to the hand and arm of man, while the form, the size and the Kies its of this animal stand in the way of its gaining the full _ results which might arise from the possession of such an organ © ™ connection with a better adapted bodily structure.

In one type of life, and one alone, can w Perceive indications of a gradual variation from the quadrupedal — towards the bipedal structure. This is the ape type, or rather that of the lemurs and apes in conjunction. In all other mammalian ypes P a o 496 ; The Making of Man. [June, the aspect of the body is distinctively horizontal. Life in trees does not necessarily produce a deviation from this horizontal - aspect, since it is retained by all arboreal mammals except those just mentioned. Yet it offers an opportunity for such a deviation, and this opportunity has been improved by the lemurs and apes. Their hands have developed a grasping power which is possessed by no other arboreal animal, and which opens to them new motor possibilities. They may assume a semi-erect or a fully erect attitude, by grasping upper branches with the hands. And this ability, in the higher apes, has led to the development of a mode of progression on the ground which is more or less intermediate between the quadrupedal and the bipedal modes. This fact is of great interest, as it seems to lead us directly to- wards the development of the bipedal habit, as attained in man. Though such a habit may be partly attained by tree-living ani- mals, a residence on the ground is essential to its full develop- ment. And it is significant, in this connection, that no existing -apes have fully given up the arboreal habit. Of the anthropoid apes, the orang and the chimpanzee dwell habitually in the trees. On the ground they are out of their true element. The same is the case with all the species of the gib- bons. All these creatures move with some difficulty om the ground, but freely and easily in the trees. The gorilla, on the contrary, seems to dwell more habitually on the surface. Its great weight tends to render an arboreal life unsuitable, and its hand is not so well adapted to climbing as that of the chimpar- zee. Yet it has only in part given up its arboreal residence. It ascends trees for food and, to some extent, to sleep, though there ‘is some reason to believe that the adult males sleep occasionally, and perhaps habitually, on the ground. It seems to be in a tran sition state between the arboreal and the surface life-habit. Of the lower apes, the baboons make the ground their place of residence. They have not lost their climbing powe however, but can ascend trees with ease and rapidity. ost of the other apes dwell wholly, or nearly so, in the trees. 1886. ]} The Making of Man. 497 gained except by a species which dwelt wholly on the ground. And life in trees absolutely requires the use of the arms as loco- motive organs, and prohibits that freeing of them from this duty which exists in man. When man ascends trees he is obliged to return to the habit of his ancestors and use his arms as organs of progression. It seems evident, therefore, that if man descended : from the apes his ancestral species must have been a form which had fully given up its life in trees, and had become almost as | awkward in climbing as man now is, ere it fairly began to change 4 from ape into man. i The adoption of a surface residence by any ape would necessi- tate certain changes in structure. Tree-dwelling apes, when they descend to the ground, present us frequently with an awkward compromise between the horizontal and the vertical modes of motion. Neither of these modes is natural to them, and to be- come properly adapted to either some change of structure is necessary, Many of them progress in the true quadrupedal man- ner, and in one ground-living tribe, the baboons, the structure of the body has suffered an accordant change. They have become true quadrupeds. In other cases there is an inclination towards an erect mode of - motion. Even among the lemurs this is occasionally displayed. Some species of these progress on the ground by jumps, the body being semi-erect and the arms held above the head. The anthro- poid apes all have a curious mode of progression on the ground, intermediate between the erect and the horizontal methods. The orang, the chimpanzee and the gorilla alike use their four limbs in Progression, but in a manner very unlike that of ordinary quad- Tupeds. They swing the body in a curious fashion between the arms. It is a sort of half-jumping, half-walking motion. Rest- ing the body on the hands, the animal swings itself between the ~ arms, and moves forward by a quick succession of such lifts and — angs. In this movement the orang and the chimpanzee bring their closed knuckles to the ground, but the gorilla is said to “ep the hand open and apply the palm to the ground.

ERENLER S a ee ee =n aces, a , 498 ` The Making of Man. — [June, -The actual result in all these cases seems to depend largely on the comparative length of the arms and legs. All the three spe- cies named have shorter legs and longer arms than man, and can thus readily lift their bodies upon their arms while in a semi-erect ` attitude. Yet they all are obliged to incline the body forward in movement. This is less the case with the gibbons, the extreme length of whose arms enables them to reach the ground with the hands without bending the body. Thus the gibbons can walk on the four limbs with the body erect. Certain species of the gibbon can readily walk erect on their legs alone by balancing themselves with their arms. They often do so, and can even move tolerably fast, the body rocking from side to side. But if urged to speed they drop their long arms to the ground and progress in the swinging fashion, Of the other forms there is no satisfactory evidence that the orang ever walks erect, though it may be able to assume the erect attitude when attacked. Mr. Savage says that the chimpanzees are sometimes seen walking erect, the body bent forward, with the hands clasped over the occiput to balance. But on the appearance of danger they immediately take to all fours to fly. The gorilla seems more inclined to walk erect, or rather in an _ down. And it stoops less, when on all fours, than the chimpanzee, since its arms are longer. When walking it balances its huge body by flexing its arms upwards. Its gait is a rolling one, from side to side. When attacked it seems to always assume the erect ` posture. In structural formation it is better fitted to the erect attitude than is the gibbon. me The subject here considered is of considerable importance byt yf = ? that the walking gibbons or the gorilla might in time become true bipeds if they should completely give up their arboreal and legs, than in man.

It was forced towards the bipedal habit by sheer necessity. On taking the ground surface for its place of residence, it was probably obliged to walk erect as the only movement to which its structure was well adapted. Neither the quadrupedal nor the semi-quadrupedal movement ` would have been suited to the proportions of its limbs, and its ancestral movement in trees may have been more vertical than is common with apes. Its bipedal development may have begun while it was still arboreal. This erect posture once fully assumed and the arms thus com- pletely freed from duty as organs of support, the animal, yet an ape, would have had an advantage of the greatest value over its “fellow apes, and over all other members of the animal kingdom, Nearly all quadrupeds use their limbs to some extent in attack and defense. Yet the necessity of resting on these limbs inter- feres to a certain extent with this duty. In the animal in ques- tion the duty of locomotion being confined to the hind limbs, the fore ones were completely set free to be used as weapons. And to this power was added that very important one of their pecu- liar adaptation to grasping, which enabled the creature to add greatly to its natural strength by the use of missile and’ other Weapons, | ‘This advantage has not been confined to man and his progeni- tors. The power of the grasping function in this direction is of- service to many of the apes, The story of the cocoanut-flinging monkeys does not need to be repeated.

They will break off limbs and twigs and,make them- — selves beds with great rapidity, but this seems the utmost limit of their constructive powers. he As for the animal from which man descended, it must have quickly gone further than this in the use of artificial weapons and in the arts of construction. Possibly its first- assumption of the erect attitude may have been aided by the use of a staff, and if so, this would naturally be employed as a club or a spear on occasion. Through uses of this kind the arms would gradually become educated to their new duties, and gain facility in im- portant movements which were impossible while they were forced to retain their locomotive adaptation. This line of argument need not be carried further. It is evi- dent that we have here the beginning of a new course of develop- ment whose end is yet in the future. The freedom of the arms and hands from the duty of support, their grasping power, and the use of artificial weapons and tools, were unquestionably main elements in the evolution of man. For under such circumstances the employment of artificial instruments would naturally be progressive. There would be no limitation to this progress from the necessity of using the arms for other duties, and such struc- tural limitation as may have originally existed must gradually have disappeared, through increasing performance of and grow- ing adaptation of the arms and hands to these new duties. The | use of clubs in attack and defense, and of stone missiles for the 7 same purposes, might readily have been adopted by an ape et constituted, and modern archzologists do not hesitate to trace all subsequent development in the arts to just such a simple begi- ning.

The freeing of the arms to the perform- ance of new duties was an essential agent in any rapid mental development. Yet it was not the only agent.. The mental devel- opment of man began in the mental development of the apes. It is but the completion of a process which extends much further back than the beginning of the human era, and through which, in one type of life, the mammalian intellect attained an excep- tional unfoldment. Human mental progress began at the high level attained by the anthropoid apes. To the causes of the un- foldment of the ape intellect some attention is therefore due. There is nothing in an arboreal residence in itself to specially promote mentality. The squirrels and other arboreal quadrupeds are not of a high intellectual grade. Undoubtedly the activity, the variety of motions, and the grasping power of the monkeys must have aided in their mental unfoldment, yet we find that the lemurs, with the same general organization and life-habits, are intellectually dull. For the inciting element to the develop- ment of the ape intellect, therefore, we must look further. Among the lower life forms the Carnivora are more intellectual as individuals than the Herbivora. Yet as groups the latter occa- sionally display intellectual conditions far higher than anything attained by the solitary Carnivora. These instances of intelli- gence are only found among the social species, and are displayed most remarkably in the communal classes, the ants, bees and beavers,! Yet even in these the purely plant-feeding bees fail to display the great variety of intelligent acts of the partly. carniv- ®rous and actively belligerent ants. It would appear, therefore, that while the activity and cunning arising from carnivorous hab- ~ aid in the development of individual intelligence, it is equally aided by social habits, and that a combination of these two requisites presents the most favorable condition for high progress > in intelligence, n fact, if we consider fully the ants, we find that these minute — creatures, with none of the advantages in structure over their — llows Possessed by man, have advanced politically and indus- 502 : The Making of Man, [June, influences alone. It appears, therefore, that social combination is a highly essential agent in intellectual development, quite as important as, perhaps more important than, any special advan- tages in structure and individual habits. The solitary life of cats, spiders, &c., while aiding to develop mentality in individuals, prevents the transmission of useful ideas. Only instincts are transmitted. Ideas die with their originators. On the other hand, the communal habits of ants and bees, while highly adapted to the preservation of useful ideas, tend to hinder individual excursions of mind and the rapid growth of ideas. An ant community is a society of strict specialists. The best condition for intellectual progress would seem to be an intermediate one, in which complete individual activity exists, yet in which social links are closely drawn, so that ideas may be transmitted by education and obser- vation, as well as instincts by heredity. And to the fullest utility of this condition some degree of carnivorous habits would seem essential. It needs no intellectuality to gather fruit from the trees. It needs often the highest exercise of cunning to capture animal prey, while it produces a variety of perilous and exciting situations to which the strict vegetarian is not subjected. Among modern apes socialism exists in various degrees. lemurs display but little socialism. Some species of monkeys = display it in a‘high degree, and it is a general characteristic of the family. Mutual aid in danger is common, education is not wanting, combination in enterprises is frequently observed, and probably through these and the like influences, observation an _ imitation have been developed to a degree not seen elsewhere among the Mammalia. Yet so advantageous is social combina- =~ tion in promoting intelligence, that the high degree of cunning = displayed by baboons, in posting sentries while robbing fruit _ plantations, is but a‘fuller development of a similar habit pe sessed by several species of otherwise dull social animals. a Among the existing anthropoid apes, however, the social habit is greatly lacking. The orang, the chimpanzee and the gorilla _ are more or less solitary in their habits. The orang is particularly s So, and is never seen in groups of more than two oF three. The | chimpanzee and the gorilla are somewhat more social, yet not : markedly so.

Unfortunately very little satisfactory information is possessed as to their habits in a state of nature, i These large apes are also strictly vegetarian. They lack the incitement to intellectual development arising from carnivorous habits. On the whole, then, their marked powers of intellect are somewhat surprising. It is. probable, if we may judge from the habits of the lower monkeys, that the anthropoids descended from social species, and have in part lost their social habits. This — is also indicated by the fact that the young of these anthropoid. apes seem more inclined to socialism than do the adults. It is also shown in the higher socialism of the gibbons, the existing representatives of the primitive anthropoids. If we seek, then, for the ancestors of man in the family of apes, we must look for a species possessed of several essential requisites, all of which can be found in no existing apes. These requisites, as considered in the preceding pages, may be briefly summarized, The ancestor of man must have been of sufficient size and Weight both to render continued life in the trees inconvenient and to give the necessary strength to combat with the perils of a Surface life. His strength, indeed, must have been sufficient, combined with his cunning, to make him a match for the larger animals, He must have been aggressive as well as defensive, and ae ginally carnivorous must have become so in a degree. Strictly herbivorous habits would have tended to check mental development. h Second, and yet more important, was the assumption of an — erect attitude, and of a true biped structure, with the complete — freeing of the fore limbs from duty in locomotion. There natu- rally followed upon this an increase of that use of missiles already n so essential a feature in the progress of m 504 The Making of Man, [June, To these physical conditions must be added the social one. ‘The ancestors of man could not have been solitary in their habits, but must have been strongly social. It is possible that the soli- tary condition of the existing great apes is a result of their strictly vegetarian habits. An anthropoid with carnivorous tendencies and i original social habits would tend to increase rather than to lose these habits, through the great benefit derived from mutual aid in conflicts with the larger animals. That man, at an early period in the stone age, waged war with the largest animals, we have satisfactory evidence in the results of archæological discovery. The original human society must have been one of mutual aid, combination in enterprises, some degree of language, or of the use of sounds conveying warning and information, protection and education of the young, and habits of observation and imitation. All these exist in some tribes of monkeys. As to vocal powers, the gibbons possess them ina high degree, though there is no evidence to show that any existing apes have specialized sounds to convey special information. It is to a group of the higher apes which possessed these characteristics in an unusual degree that we must look for the ancestors of man. If we be asked for traces of such a group we can but point to man. The ancestral line has vanished in that of its descendants. The existing anthro- poid apes are but side issues in the problem. a The development of the social condition and of the edu _ process must have had a vigorous influence in the enlargement of the brain. In man the dividing line between the physical and the mental powers, as organizing agents, was finally passed. A tribe had arisen, for the first time in the long history of anim = life, that trusted more to its mind than to its muscles, and which _ had begun to substitute artificial for natural tools and weapons. _ With the attainment of this condition there was taken the first decided step in that long line of mental progress which has pro- _ duced the brain of man. In all preceding ages evolution had been mainly physical, and exerted its chief influence upo? if limbs and muscles. Now, for the first time, mental evoluto" gained the supremacy, and development centered itself in tY cational ae -ceased to change. _ Under these circumstances there is nothing very SU ha, al V say E b ’ brain, the organ of the mind, while the body, in great measure, rprising 19 the fact that the human brain has attained an exceptional de ae a a, ee ee ee . | d Fi i Ree ee a ae FT as eta : ae 1886.] Progress of N. A. Invertebrate Paleontology for 1885. 505 opment, or that its growth was strongly marked at a very early date. How far it has increased in size over that of its non-human ancestor, we cannot judge from comparison with the brains of any existing apes, since these may be of a much lower grade of development. They are probably not fair standards of compari- son. And if the body stood almost unchanged for ages, and all the influences of nature centered themselves upon the brain, a considerable increase in size and some variation in structure were inevitable consequences, and it is not easy to perceive, under the circumstances, that there is anything extraordinary in the special growth of the human brain. 7 In the making of man, then, we perceive the critical step that took the animal world over the dividing line between physical and mental evolution; and in human development we are con- cerned, not with the maturity of an old, but with the infancy of a new evolutionary process, which is full of far-reaching and extraor- dinary possibilities, of which the intellectual progress yet attained by man may be but the beginning. There may be*needed as many millions of years for the full development of the mind as have been consumed in the evolution of the body, and the organ of the mind may yet attain an importance in the scheme of the physical organism of which we have no conception. 10: REVIEW OF THE PROGRESS OF NORTH AMERICAN INVERTEBRATE PALAZZONTOLOGY FOR 1885.

Weighing more than the air they displace, and using no muscular exertion to sustain themselves, they still, in the sense of getting nearer to the earth, do not fall. When we seek for a motive power which is competent to resist the weight of the bird’s body, and neutralize the resistance of the air to its translation, we seem baffled. Bird and air form a material system in which no other object is in- cluded, so that it is impossible to obtain power from the wind. Wind is motion of the entire system as a whole, compared toa fixed object, as an observer, and such motion does not affect the motion of the parts. Wind from any direction, or at any velocity, or entire calm are differences of air-conditions to an observer, but not toa bird. We are therefore limited to the gravitating force of the bird’s body to find the power producing the phenomena, as it is nowhere else discoverable. But here we are confined to certain notions derived from sticks and stones, and in fact all other falling things, and they do not seem to help us in explain- ing a thing which does not fall. We are likewise taught that the direction of the gravitating force is vertically downwards, 7, e., in a straight line from the body manifesting it to the center of the earth. What we understand by this “ direction” is, that when — gravity does work, when it is in the act of making anything dif- ferent from what it was before, when it moves a thing at rest, or Stops it when in motion, or accelerates it, or is in the act of man- esting energy in the way which we call “ work,” that the “ direc- zo tion” in which it does it is vertically downwards. How then can >- this force drive a body upwards, or translate it horizontally ? : Still further. Although we admit, when our attention is called to it, that weight is the result of gravity acting on a quantity of — Matter, we are apt to confound mass, and weight, and gravity into — wog identical thing. This is inadmissible, since the doctrine of : € correlation of forces is established, as it is entirely possible to. _ í change every atom of gravitating force which a body manifests _ into some other form of force, in which case either the former is- —— Separate from the quantity of matter or the latter is created. We. = §ravity as something apart from body, and still we have no i wledge of it excepting what we are enabled to infer about it. 5 fre it not for these inferences we would be shut up to tbe, 516 Gravitation and the Soaring Birds. [June, ity, as a separate force, was simply non-existent, for it never man- ifests its power but in connection with body, and the action of the body is our rule to determine the action of the force. It would be expected that in dealing with agencies of this kind, the greatest care should be exercised lest we fall into errors, and it is apparent that many of our notions in regard to gravitating bodies have been brought up from generalizations which do not include all the facts. The soaring birds have been omitted. To the extent of their exclusion our ideas are subject to error. It is imperative that they be brought under the dominion of gravity, and that the phenomena presented by them shall have due recog- nition in determining the characteristics of that force. -I have shown in the pages of this magazine that these birds _ Can be reduced to lower terms. A plane resting in air, and acte on by a force, exhibits all their activities, and up to this time, SO _ far as my knowledge extends, the mechanical world has failed to = work on elastic air. . ing propositions, which are self-evident on statement. = | _ otherwise noted, acceleration will be supposed to have termina 2 ~ uniform motion progressing. recognize the facts eitubited by such a body, when subjected to 1886, | _ Gravitation and the Soaring Birds. : 517 As there is no authority for the value of frictional resistance of air on smooth surfaces, and as I have failed to measure it by any exper- imental test at my command, on account of its extreme smallness, the argument would be in no wise affected if it were not taken into account for any of the velocities that we shall deal with. The reader may therefore place upon it any value within reasonable limits. Let A B represent one of the edges of a plane, say one foot Square, resting in air, and of the same weight as the atmosphere it displaces, 1. The only actual or conceivable work the plane can be sub- t to under the dominion of any force whatever, is either air Pressure upon its sides, or resistance to atmospheric surface or skin friction, parallel to itself or in its own plane. 2. From the law of fluid pressures, and the contrary and equal aracter of action and reaction, a force operative upon the plane B from any direction, does work in one, or both, of two ways, z., either in it or at right angles to it. 3. Forces in the direction of c d, or in the plane in any direc- tion, are not resolved by the plane, but work to their full value in piers independence of each other, as they are right-angled orces, : jec ch A vi 4. Forces from any direction, excepting in the plane and nor- mal to it, are resolved by the plane into those two directions. 5. Any number of forces, not in the plane nor normal to it, Operate upon it in the resultant of one force, from one direction ; d this resultant, if not already in the plane or normal to. it, is — resolved therein by the plane. | _ 6. It follows that the plane can be subject to work only, (1) in its own plane, (2) in a direction at right angles to its surfaces, (3) in both of these directions. Y the plane is compressing air, and as the resistance of the Pa atmosphere to motion in this direction is very great, the velocity.

The nature of the work done by the force acting normal 518 Gravitation and the Soaring Birds, [June, plane into those forces in the same ratio that the direction of the force bears to those directions. To illustrate these propositions we will suppose a force, e f, in- clined 18° from ¢ d, to operate on the plane A B, with a value of sixty foot pounds per second. The plane would instantly resolve / _ this force into twelve foot pounds in its own plane in the direction 2, and forty-eight foot pounds in the direction ¢-d, at right angles to it, when it would be reasonable to suppose that the twelve pounds would drive the plane against friction of air with far greater velocity than forty-eight pounds would against air com- pression. If motion in the direction 2 were resisted to the point of pre- vention, all the force, e f, would do work in the direction ¢ æ, when the entire sixty pounds would be setting up air pressure, and the plane would be in equilibrium in the direction I 2. very small force, say one or two pounds, would now drive the plane in any direction, say towards 1, with considerable velocity. | It is obvious that the sixty pounds of air pressure would be enough to supply the twelve pounds needed to balance the force acting towards 2, and the one or two pounds additional needed to drive the plane towards 1 with a velocity we will suppose of 150 feet per second. If we suppose the motion of the plane in the direction e f to be at the rate of thirty feet per second, it will = move in opposition to the direction of the force as fast as it does = with its direction, and we will have the anomalous case of a force = developing enough force in moving a body to move several such bodies through the same space in the same time diametrically | Opposite to its own direction ! . This seems absurd, and needs rectification to make it tolerable. We have entirely overlooked the fact that the moment e f began the task of working it abandoned the direction in which 1t re- _ sided, and four-fifths of it went over 18° to c d, and one-fifth -went over 108° to A B. The direction e f is vacated, it is without significance. For all the influence it has on the plane it mightas well not exist. There is zow no movement of the plane against _ the direction of the force whatever. Vow, the forces working 0° _air, and driving the plane towards t, are at right angles to each other and do not resist each other. The problem is, the ger of a force to drive a plane faster edgeways than flatways throug ee E R EREET PENA: 1886] . Gravitation and the Soaring Birds. 519 In going over, the one fifth that traveled -108° was wasted, 2. ¢., it neutralizes an equal amount of the other, so that only forty- eight pounds, instead of sixty pounds, are available to drive the plane edgeways; but this would be competent to produce an enormous velocity. Had the force been originally in cd, the entire sixty pounds would have been available. But when we rectify the diagram so as to make ef vertical, and add two pounds weight to the plane, so that the force em- ployed will be gravity, all the ghosts, which we supposed laid, at once reappear in vastly magnified proportions, The outcry now is, that the law of falling bodies is violated, for a body in falling can do no more work than sufficient to lift it through the same Perpendicular height. It seems that here is a good place to establish an €xception, and we will examine into the way in which it may be done. While the plane A B is level, the gravitating force is not re- Solved by it, but acts at right angles to the surfaces, when lateral Motion will be resisted by nothing but atmospheric friction, and a this the one or two pounds is competent to overcome, driving the plane to D while it is falling the thirty feet in which the sixty re Pounds is developed. It will therefore pass to H, the resultant of two motions. It will simply have a lateral motion of 150 feet Sways through the air added to its fall of thirty feet. To its Work of air compression there will be joined an additional item — x work in Overcoming 150 feet of atmospheric friction. The i eS att ere ts IN AT be z ES 8 en > Bate: | Se...

Gravitation and the Soaring Birds. - [June, | ; force developed in the fall will be enough to supply the lateral force and still leave fifty-eight or fifty-nine pounds to go to waste by falling to the tension of the surrounding air. - But this would not be “ soaring,” as the plane will soon reach the ground, = If we now throw the plane over on an incline of one in five, or 18°, we have an additional twelve pounds of lateral resistance to overcome, which the sixty pounds is entirely competent to effect, together with the one or two needed to carry the plane to ¢, and still have forty-six or forty-seven pounds more than is wanted left over. We now have the plane elevated as fast as it falls, so that its resultant passage to D is the horizontal translation of flight, and a body in falling does work enough to: not only lift it to the same height from which it fell, but to move it against air resist- ' ance, and have a large surplus left over! This seems impossible. But the reason of such appearance, aS already shown, is that we are entertaining a fallacy. We are supposing the direction of the gravitating force to still be vertical after it has gone over eighteen and a hundred and eight degrees. We have, as a matter of fact, changed the direction of gravity more than we have slanted the plane. One-fifth of its total amount has gone over 108°. The plane has taken the same lib- erty with the great cosmical force of gravitation that it would with any other force. It refuses to be operated upon by any energy whatever of a mechanical kind while doing work on elastic - fluids, excepting in the two directions mentioned, and any force whatever, not in either of these, is instantly put there by the plane. To say that the gravitating force is still vertical, and has not gone over, is to increase the difficulties of the °as° = and not to abate them. In such event the law of fluid pressures is violated, which demands that they be at right angles to the compressing surface. The plane would also fall vertically with- _ out lateral motion, all of which is impossible. Some force is -~ actuating A’ B in its own plane and normal to it. From whence comes it? There is but one source of supply. The plane me simply resolved gravity until its perpendicular line has beer _ vacated, and re-located at right angles to the lateral force acting in the plane, which lifts no weight, and resists nothing whatever but friction. The plané, in its translation towards <, is moving = towards é, but not towards e’. It is going contrary to the abstract . eS pee ES E ee ee A 1886. ] Causes of Forest Rotation. 521 direction of gravity, but not contrary to the direction in which that force is now working, which alone concerns us, The whole matter hinges on the ability of a plane to resolve the gravitating force as it resolves other forces. In doing so it does a very wonderful thing. It makes of gravity a continuous motive power. It introduces a new idea into our conceptions of things, and makes it imperative that we rectify our notions of the gravitating force so as to admit these facts, which we have not hitherto recognized. It dignifies the soaring birds into the position of favored crea- tures of nature. They inhabit a universe of their own. The horizon of their world is not the level of the sea, but the incline of their own wings, which they can change at will. Their gravi- tating force is either in a straight line from their bodies towards the center of the earth, or the moon, or the sun, or any of the stars of heaven, indifferently, as it suits them, to sleep on the breeze, to play at gymnastics high in air, to enact the rôle of the highway robber, or to serenely float from zone to zone. I have now presented the case of the soaring birds to the ex- tent of my ability. The task could have been better done by a Specialist in analytic mechanics, as it is in this sphere that its sig- nificance lies. The whole matter is extremely peculiar. In con- sequence of the throng of preconceived ideas which tend to cast the obscurity of night over the whole case, the evidence upon which it rests, although axiomatic throughout, is difficult to see. “ne mechanism also seems devoid of organization, a simple plane — is all there is of it,@na still it has the power to change the hori- zon of the world to suit its own purposes.

CAUSES OF FOREST ROTATION. att BY JOHN T. CAMPBELL. : Lees a P a letter recently received from Dr. S. V. Clevenger, he _— io | tioned a case coming under his own observation on the North J -CUS railroad, in Minnesota, near Mille Lacs, where the railroad 522 | . Causes of Forest Rotation. Hune, company cut the pine timber off of their own alternate sections for railroad ties and other purposes. This pine forest was suc- ceeded at once, to all appearances spontaneously, by oaks. I have often heard North Carolinians say the same thing about old fields in that State, when abandoned as worn-out land, that some timber different from that which had been cut off when clearing the land at first, would spring up spontaneously, or ap- pear to be spontaneous. I can speak only for my own locality, not having observed any me other. Here (West central Indiana) we have in many localities a prevailing species of timber, but no species that exist to the exclusion of all others, as is often the case with pine. But of our prevailing timber, or any other kind, sugar maple excepted, none seem to be reproducing their kind in their immediate vicin- ity. For reasons which will follow, I surmise that nearly all forest trees bear and shed leaves which are unfavorable to the sprouting and growing of their own seeds. The most notable instance I can now think of is the red cedar, introduced into this | vicinity from the north and north-east about forty-five years ago i for ornamental purposes. I don’t remember at what age they = began bearing seed, but I think as early as ten years, counting them to have been three years old from the seed when trans- planted here. Until certain kinds of birds bezan to eat their seeds, they were not found growing wild in the forests. I do not know what birds eat the seed, but evidently all do not, else they would have been planted as soon as the pargnt trees bore seeds, which was not the case for fully fifteen years afterward. When these seeds pass through the craw and intestines of birds they _ are prepared to sprout when they come in contact with the ground of the proper degree of moisture. Nurserymen, when they _. gather them direct from the trees, are obliged to put them through some process of scalding before planting. The birds drop them Ppromiscuously over the country, where they have been appearing within the past fifteen years numerously, and only rarely before about that time. They are a hardy tree, and bid fair to becom® OnE of the forest trees of the future in this part of Indiana. It " _ reasonable to presume that these seeds would be more abundan 4 dropped under and very near these parent trees than elsewhere, _ for quite probably the birds that nest in these trees eat their see Yet no young cedars are ever seen to sprout and grow e 1886.] Causes of Forest Rotation. : 523 The same is true (7. e., not growing their young within the radius of their leaf-fall) of the white pine, firs and other evergreens transported here for ornamental purposes. Some of the older ones are twenty inches in diameter, and have borne seeds many years, I have long observed that the seeds of forest trees shed upon the forest leaves, sugar maple excepted, cannot sprout. This is very specially the case with the American poplar seeds. Yet I often find in the woods clusters of young poplars, varying in age from one year to sixty and seventy years. Last year I found out how this comes about. If the seeds happen to fall on the bare ground of the right degree of moisture, they at once take root and grow. If about the time these seeds are falling there should be a hog in the woods and he should have an appetite for ground Worms, he would thrust his strong snout through the leaves into the ground and cast u p fresh earth in a very promiscuous manner, and every poplar (or other) seed that should happen to fall on that fresh ground would stand a good chance of growing. I saw young poplars just barely sprouted under the above circum- stances, while at the same time other and brother seeds had fallen on the leaves neat by, where they lay dead and as dry and crisp as smoking tobacco. are Sometimes squirrels, hares, ground squirrels (chipmunks) dig eae through the leaves into the ground for food which they find there, I presume, and these places give a chance for one or more seeds to grow, and the hoofs of heavy bullocks (and in times past the elk and buffalo) have made deep tracks through the leaves into the ground, which would give a like chance, whilst the coating — of leaves would prevent the growth of all the rest. The hogs were brought here at the very earliest time of settlement, turned loose In the woods, where they multiplied rapidly, becoming wild, fero- cious and more dangerous to man than bears, wolves or panthers. _ M © = „ause of its rapid growth.

The trees bore a bountiful crop of seed last May, and of the first that matured and fell, I tried to sprout about a dozen by placing them in good ground and water- z ing every day for several days. But as I could not give them all my time, they dried up between waterings and died. After these had died, there came a threatening, blustering storm one Sunday a evening about sundown, which shook off the remaining soft maple seeds. They were so abundant that they gave the streets a buff color J where they fell. The wind was followed by a light, steady rain, which = continued several days, alternating with sunshine. This was favora- ble to sprouting these seeds, and they came up all over the streets, yards, and gardens as thick as weeds in a neglected field, a thing that never happened before in the twenty-two years I have resided in the place. Those in the street the cows ate up ; those in the gar- dens were weeded out, and those growing elsewhere were killed by the following summer drought. On the south end of my gar- den, where a cellar drain terminates, the proper moisture was ` maintained through the drought, and there stands a thick cluster of them, the only survivors, so far as I know, of the millions that sprang up last May. After these trees are three years old they can be successfully transplanted into any kind of soil we have et here, and seem as hardy as any dry-ground tree ; but during their infancy the conditions must be as before stated or they die. So = thinkitis clear that this tree will never. be self-planting, except - along the low, moist bottom of the streams where we find it native. A The hard sugar maple does plant its own seeds within the radius of its own leaf-fall. In 1884 there developed a local rain in the south-east quarter of this (Parke) county which continued _ showery for several days, alternating with sunshine, just as the ~ sugar maple seeds were falling. The result was as in the case of the soft maples last May; all the seeds sprouted. As this favor- able condition did not happen when the other trees were shedding their seeds, the result in that part of the county is, that the sugar = maples are a hundred to one of all the other young trees sisi : bined, and the deep snow and cold winter that followed, making -a hard crust on the snow, prevented the sheep, cattle and rabbits : : (hares) from browsing them down, though it starved thousands ‘of rabbits, as their bones found in hollow logs and trees abun- dantly attest; but it saved the young sugar maples till they a*° Ba Ba Se Nien iy ha eR ee aie aan 2 oils E oa Pa ss eee 1886,] Causes of Forest Rotation. 525 now large enough to be safe from every enemy except man. If he were out of the way for 150 years about all the present forest trees will have lived out their time, and these young sugar maples would be almost the only trees of the forest in the area where a rain happened to fall with the seed. In the other thrée- quarters of the county that state of things would not exist, for there only the lucky seed that fell where a hog had rooted or a bull had trodden has made a tree, and this luck was as favorable to other seeds as to the sugar maple. These maple seeds send rootlets right down through the coating of leaves into the ground, and I have seen, over an area of many acres at a time, a maple Sprout for every four inches square, or nine to the square foot, none seeming to have missed sprouting. In replanting the ground where the present forest has been cut away, the sugar maple makes the least show of all the forest trees. As an infant it seems to thrive best in the shade of older trees. How the oak can take the place of pine where there are no oaks in the vicinity to bear acorns, I am not sure, but it is easier and more rational to believe that there is some natural agency for transporting the seed of the apparently spontaneous new tree, than to believe it to be really spontaneous, whether we understand the transporting agency or not. One of the most industrious and persistent seed-transporting agencies I know of is that ubiquitous, energetic, rollicking, med- dlesome busybody, the crow.

At length they get through, by finish- ing their work or tiring of it, and disperse. As they start to fly away many, if not all, will drop something. I have found these to be acorns, walnuts, hickory-nuts, buckeyes, sycamore-balls, sticks, egg-shells, pebbles, &c. As a crow leaves an oak he will pluck an acorn which he may carry five miles and light on a beech tree, where something else will attract his attention, when he will drop the acorn and may be pluck a pod of beech nuts and fly away somewhere else. ; The squirrel is also a nut-transporting agent. The hog will eat his nut where he finds it, but the squirrel must find some suit- able place to eat his nut, like some fastidious boarders I have known, who would not and could not eat if they failed to get their own conspicuous place at table. The squirrel will select his nut, take it in his mouth, skip along a few yards, pause a moment, then a few more skips and pause, preferring a fence or fallen tree to the ground for his roadway. He will sometimes carry his nut several hundred yards, not to his home, but to some conspicuous tall fence-stake or dead projecting limb of a tree, on which he sits on his haunches, his tail curled over his back, and in this striking attitude he complacently gnaws through the shell of his nut to Set the kernel.

GREENOUGH. ae the month of June last, I heard through friends of the nest of a humming-bird (7Zrochilus colubris) at Cotuit, on Cape Cod, where I was then staying, and having long wished for such an opportunity, I immediately decided to do what T could towards observing the growth of the young. Unfortunately the position of the nest made this rather difficult, for it was on a small dead branch of a yellow pine tree, some distance from the trunk and twelve to fourteen feet from the ground, or thereabout. 4 Of four nests’that I have seen, all in Cotuit, three were in yellow pines and one ona silver poplar, two about twenty or twenty-five : feet high, one nine or ten and the last as above stated ; the one Ren on the poplar was on a small dead branch ; with regard to those that were highest up, I do not remember whether they were on oes dead limbs or not. ie The young birds were first seen by me on a Saturday, the pre- f vious Wednesday a lad, whom I sent up the tree, reported two i eggs, as he had already done once before, so that I cannot z when the birds were hatched, and had feared to make daily visits at this stage lest I should frighten away the old bird. By means of a long step-ladder, improvised for the occasion by tying t0- gether two ordinary ladders, I was enabled to view the young within a few inches. Though very small, they were rather larger than I had expected them, and appeared to be already covered for the most part, a bare streak extending, however, down the middle of the back; nee Fic. 1,—Diagrammatic sketch from memory of young 5 ~ when first =n = trifle reduced; heads too small in ¢ccirostral type * oe extending $ : below the eye, I am not sure, I feared to take the young an s -i 1886.] Observations on Young Humming-Birds, 529 closer inspection lest I should injure them or frighten off the old bird, and I particularly wished to ascertain other points which could only be done by leaving the nest undisturbed. The two young lay quite still at the bottom of the nest (which was deeper than those I have seen after the birds have left, and with sides and edge beautifully finished) with their heads pointing the same way and their bills somewhat upward and against the side of the nest. The annexed diagram, from memory, will give a fair idea of their general appearance at this time, it being borne in mind that spe- cial attention was paid to the head and bill. On the following Thursday I again went up to the nest, and found the birds somewhat grown and the typical humming-bird bill beginning to show itself. I can best describe it by saying that it looked somewhat as if it had grown out of,or on to the other like an extraneous thing, but was still only a fraction of an inch long, say a quarter or trifle less. During this time the old bird had been on the nest nearly always when I passed by, or if aWay was very soon back. A few days later, however, I found her absent for some time, at . different hours of the day, and feared some acci- dent had happened, but on watching near by I finally saw her return and feed the young and a neen then sit on the nest again.

After the young got a little larger she could be seen to thrust her bill into theirs; she fed first one and then the other, apparently by re- Surgitation from the crop, for a motion could be seen in the region- of the throat, and after feeding one she would hold up her head for an instant before feeding the other. In a few days she ceased to brood the young, but fed them very frequently. I often saw her fy to the nest, and when she had gotten near she would generally 2 _ Polse and look round before perching on its edge.

Some ten days or thereabout after the young were first seen, their bills began to show above the edge of the nest, and soon after were generally plainly visible.

I watched all the morning, but neither bird left the nest, though both seemed very restless; on my return in the afternoon only one young bird remained. I saw the old one feed him once or twice, and noticed that she approached him from a different direction to what I had before seen, coming downwards from the clump of pines, on the edge of which stood the nesting tree, instead of the open glades from which I had always before seen her approach, I accordingly laid on my back and looked upward, and presently saw her return and perch on a bough be- . side another humming-bird, feed it and fly away. I now watched the bird on the bough very carefully and soon saw it fly, and this it did repeatedly at short intervals, sometimes down, again up, on a level and in curves: except for the shortness of its flights, I rs could see no difference from that of the old bird (and as it was well grown, had I seen it casually I should not have known it for a young one); there appeared to be the same precision of move- — ment, facility of turning and rising, and the same humming style a of flight, though I was not near enough to hear any sound. Once toward the end of an unusually long flight, I thought, I Perceived signs of fatigue, but do not feel sure of this.

BY PROFESSOR J. E. HENDRICKS., ; A Mr. I. Lancaster has published, through the medium of the American Naroratist, his very interesting and valuable observations of soaring birds, and has, in the April number (No. 4, Vol. xx) given an explanation of the mechanics of soaring that might lead non-technical readers astray, a brief review of the “ Mechanics of Soaring ” may not be unprofitable to some of the readers of the NATURALIST. ; << As much that Mr. Lancaster has said is in accordance with the recognized principles of mechanics, I will not encumber the pages of the NATURALIST with a general review of the whole article, but will confine this paper mainly to a consideration of the question proposed by him and which he regards as a crucial _ test of the validity of his theory of soaring. al In investigations concerning the operation of forces, it 1s 1M- s portant that the distinction between continuous and momentary ee forces be kept in view. Although all forces require time for their operation, yet such forces as act for a short time and then eeu to act, are called momentary forces, and the time during which they act is not considered ; the velocity induced being constant _ and equal to the intensity of the force divided by the mass. t = When a force acts uniformly for a considerable portion © time, it is called a constant force, and the time of its action ee _ involved in the velocity it induces, which is represented by the __ intensity of the force multiplied by the time and divided by the mass or weight of the body. : _ Although we do not know what produces the ROE. _ of gravitation, we know, as manifested on the surface* “ d earth, it is a result of two opposing forces (a centripetal peas ~ centrifugal force) whose difference at any point on the earth S a a wey —— ‘ge: of thirty feet per second. ie 1s thirty feet per second, will be 12 sin? @ lbs., and because its. .

Weight, therefore, or gravity, is a constant force, and difters in no respect from any other constant force. It is found by experiment that a current of air, having a velocity of thirty feet per second, and meeting a stationary plane, the projection of which, in the direction of the motion, has a superficial area of one square foot, exerts upon the plane, in the direction of the current, a force = 2 lbs.

If then we suppose the weight of the plane to be twelve pounds, and its descent vertical through a quiescent atmos- Phere, while the plane surface is horizontal, the case will be that of a falling body in a resisting medium, and when the plane shall have acquired a velocity of thirty feet per second, we know, from the €xperiments above referred to, that the plane will meet a con- stant resistance of twelve pounds, and this being the weight of the plane it will thenceforth descend with the uniform velocity If while thus descending, in equilibrium, a momentary hori- ` zontal force, the intensity of which is equal to gravity, be im- Pressed upon the plane, because it would impart to one pound a velocity of thirty-two feet per second, it will therefore impart to the plane, the weight of which is twelve pounds, a velocity _ of only tz X 32 ft, or 234 ft. per second, instead of 1000 ft. per Second as assumed by Mr. Lancaster. s If now the plane be tilted so as to make an angle @ with the vertical, the vertical pressure it will encounter, when the velocity _ RT hee” Sty % 534 Editoxs’ Table.

The conditions of the fitness essential to survival were thus originally those of physical endurance, and as life multiplied and inorganic nature receded in importance as a factor, these conditions came to depend more and more continu- ally on intellectual development or adaptation to the wants of the most intelligent organisms. The most useful and successful man in the Plymouth Rock colony was he of the strongest arm and broadest shoulders, but the most useful and successful man | of the metropolis to-day is he of the greatest business. tact and A shrewdness and the broadest human sympathies. When we speak of the “ survival of the fittest,” it is obvious that we must keep before our minds a clear idea of the sense in | which the words “ survival” and “ fittest” are used. If the con- ditions of a certain sense of the word “survival” pass away or indefinitely decrease in relative importance, we cannot reasonably €xpect to apply the word in that sense as if it were invariable. It is necessary, instead, to employ a more constant and general signification of the word. : If there were no universal and overwhelming convulsions of nature after the arrival of the highest members of the scale of ` animal life at a plane of absolute intelligence, we are warranted in 2 Supposing that the most intelligent mammals, at least, were . capable of preserving themselves from destruction and burial by the lesser convulsions of nature that occurred from time to time. Moreover, if we assume, for the sake of argument, that man descended from the highest development of anthropoid apes Whose existence in prehistoric times is known, we must admit the occurrence of a considerable interval between the cessation ) of such convulsions of nature as were likely to bury and preserve 7 the remains of anthropoid apes and the attainment by the anthro- the dead in a manner calculated to preserve their remains for modern scientific inspection. ae The longer this intermediate period is supposed to be, the © Steater the intellectual development which, under the laws of volution, should take place in the course of it, The reasonable ence is that the greater the gap between the highest known = of anthropoid ape and the lowest known form of man, the veoh important, relatively, must have become the social and Moral conditions of development, while the physical conditions poid of a sufficient degree of intelligence to suggest the burial of -536 Recent. Literature, [June, anthropoid apes appear therefore to require that there should be a “missing link,” in the sense that physical evidences of inter- calary types are unpreserved. The “ survival” of the fittest, at a certain period in the history of life, means exactly such surviv as would make it improbable that many remains should be pre- served, and this survival only the fittest would, under the circum- stances, attain. Such anthropoid apes as were capable of generating man should have been superior to those whose remains were pre- oe served because they had not intelligence enough to protect their lives. The first considerable preservation of primitive man would begin when he ventured on navigation; but his remains so pre- served will be “ missing,” until such time as “the sea gives up her dead.” ; —— The committee of Congress which has been investigating the U. S. Geological Survey has not dealt kindly with Major Powell and his charge.

GEOLOGICAL SUR- vEY.—Besides the usual reports showing the progress in the sur- vey by the different members, the body of the volume is filled by the following memoirs: Hawaiian volcanoes, by Capt. C. E. Dutton; Abstract of report on the mining geology of the Eu- reka district, Nevada, by J. S. Curtis; Popular fallacies regarding the precious metal ore deposits, by A. Williams, Jr.; A-review of the fossil Ostreidæ of North America, by Dr. C. A. White; A geological reconnaissance in Southern Oregon, by I. C. Russell. Having already called attention to Dr. White’s valuable essay, we would briefly notice Capt. Dutton’s elaborate account of the volcanoes of the Hawaiian islands. Besides detailed descriptions, accompanied by excellent illustrations and maps, of Kilauea an Mauna Loa, the author also describes Mauna Kea and the old _ extinct volcano of Kohala and the lava fields of Hualalai. The descriptions of the mountains and lava streams and beds : are careful and the facts presented will be important to the stu- i dent of vulcanism. The author does not regard Kilauea as a crater, but considers the depression in that mountain, which he, designates a caldera, as due to the “dropping of a block of the mountain crust which once covered a reservoir of lava, this reser- voir being tapped and drained by eruptions occurring at muc lower levels.” 3 Acknowledging that volcanic action and regional uplifting are really associated phenomena, the author states that the cause 1S mysterious, the attempted solutions not standing criticism, thoug! suggesting that the effects are due to expansion of the earths crust in the region involved. + The three plates which we are allowed to reproduce from " volume, will convey some idea of the grandeur and beauty this volcanic region. ee a E ee ee E E E ER AE ee E E MR Professor F.

THE AMERICAN ORNITHOLOGISTS’ UNION CHECK-LIST OF NORTH American Birps.'—This catalogue of North American birds, as the latest issued, is the most complete, and will be a useful work of reference to ornithologists. The volume also contains a digest of rules of nomenclature adopted by the American Ornithologists’ Union. There has always been a large proportion of authors of works on birds with literary rather than scientific tastes, so that the conclusions of an ornithologists’ union will require careful Scrutiny on the part of the scientific investigator. The danger from the side of letters is the subordination of the true interests of scientific research to red tape and literary archeology. The way to do this is to excuse authors from giving definitions to the new words they introduce, and so to open wide the doors to ama- teurism and its attendant confusion and redundancy. We are glad to observe that the new code agrees with the old ones in re- quiring that new generic names shall be defined in order to be adopted. But a few pages later the code contradicts itself by say- Mig that when an author describes a new species which belongs Oa new require definitions in all cases.

At Raheng this line would be joined by another from Maulmein, at the mouth of the Salween, in British Burmah. North of Kiang Hsen the railway would be produced along the Meh Kong valley to Kiang Hung, fifty miles from ‘the Chinese town of Ssumao. By taking this route the Mass of mountains lying east of the Irawadi is avoided. The Burmese Shan States east of the Irawadi are believed to Contain a million to a million and a half of inhabitants ; the Sia- mese Shan States about two and a half millions, while the Meh Nam valley, south of the latter, has about three and a half millions. e Shans are described as a cultivated people, free from caste, lous and energetic, hospitable and frank toward strangers, eager for free trade, and of great capacity as petty traders.

Mr. Grenfell ascended it to 22° 32’ E. long. and 10’ N. lat.; it therefore runs nearly parallel to the main stream. The Boruki is formed by the union of three rivers, one of which, the Juapa, was ascended as far as 23° 14’ E. long. and 1° 1’ S. lat., where it was still an open water-way one hundred yards wide and twelve 18” S.

These reports are highly interesting, and display, in an instructive manner, the points of agreement and divergence between the geologists of the different countries of Europe. The digested re- sult will constitute, when completed, the most valuable synopsis of the subject yet written. Unforeseen circumstances prevente the completion of the reports of some of the American commit- tees, and the United States Geological Survey was not ade- ` quately represented, although Mr: McGee did his best with the means at his disposal. The color system adopted is, as it should be, founded on that which has long been current in all countries. The new system proposed by the U. S. Geological Survey was not adopted, but a letter’ from Major Powell, recommending it, was read. Some of the details for representing details, proposed by Major Powell, might, we think, be introduced with advantage. The important American formations of the Laramie and Puerco must also represented by appropriate colors. We hope that the Congress of London will make up for these deficiencies, and add to the good work done by the Congress of Berlin whatever may be necessary from other portions of the earth. The report is well printed and is, in all respects, what was to have been expected of the distinguished secretary of the Ameri- can Committee. 5 > First APPEARANCE OF THE GrRassES.—At a meeting of the Geologists’ Association, held at London, April 2d, J. Starkie Gardner discussed the points bearing on the geological _ period at which grasses first commenced to assume a preponder- ating position in vegetation. Their value and importance at the present day were first sketched, and it was remarked that they ` Occupy under cultivation one-third of the entire area of aie inclusive of lakes and mountains, while, exclusive of malt an a into this country alone. There are over 3000 species fitted to _ competition under no matter what conditions, with the result that a about ninety-five per tofth pl ‘ g : gi dinary meadow- land are grasses. The conclusion arrived at was that mor no great development of grasses until towards the close P re -Hocene, no definite remains being associated with any O eects _ older Eocene floras of temperate latitudes.

Further, it was shown that the dentition of all the early Eocene herbivorous Mammalia was adopted for crunching fruits, snapping twigs, and grubbing of roots, rather than for browsing on such food as grass, so that the evolution of true Graminivora, as well as the Specialized Carnivora that prey on them, must be post-dated to the appearance of the grass itself. The geological history of the whole class of insects was reviewed, with the object of support- ing the conclusion arrived at as to the post mid-Eocene date of grass. Older remains of grass may, however, occur in the last series of Tertiary deposits in Spitzbergen, but as yet their age has not been accurately correlated.

VARIATIONS OF TRADESCANTIA VIRGINICA—An interesting case ‘of floral variation is under observation by the writer in the shape of a highly aberrant form of Tradescantia Ur grea, OF Spiderwort, also called, in quaint allusion to the ephemeral nature of its petals, “ widow’s tears.” Said plant presents, as the result of thirteen years’ cultivation, the curious aspect of a monocotyle- donous plant having in bloom, at the same time, flowers of dimer- ous, trimerous, tetramerous, pentamerous, hexamerous and hept- amerous types -respectively, each flower having twice as many stamens as sepals, petals or carpels of ovary.

The sexual organs arise as buds upon a common branch, the single antheridium being terminal and decidedly curved; the oogonia varying in number from two in the typical form of the species to eight or nine in some specimens of the variety. They are arranged in a circle about the base of the antheridium (Fig. ,? The specimens when first collected showed no peculiarities, but after being kept for a week or two in rather confined quarters, a large proportion of the fertile branches developed abnormally, owing no doubt to the unnatural conditions in which the plants were grown. The accompanying figures will show the more peculiar cases observed. In all of these it will be seen that the branches that under ordinary circumstances would develop into the sexual organs are here variously modified. In Fig. 2 the antheridium is replaced by a filament that is in all respects like an ordinary vegetative filament. n Fig. 3 the antheridium is perfect, but the oogonia are re- placed by slender filaments. ig. 4 one odgonium has developed, but its apex is pro- longed into a filament like those in F ig. 3.

My Sophomore class of over fifty members begins its second term in- tany the last week in February. The college vacation is during = mber, January and most of February. n a class has had one term of botany as freshmen in the previous “oncerning stems and buds. The first field exercise mas the making of a careful drawing of at least three inches of 554 | General Notes. [June, the tip of an elm and of a maple branch. The students were given no further instruction. They are never told what to look for. From my pile of sketches and descriptions I quote the whole of the first one without making any selection : “1, Drawing of maple branch with terminal and opposite lat- eral buds. Stem thick and of a red color, covered with small specks. Wood not so tough as elm. Buds more tender. 2. Drawing of elm twig with a terminal bud and alternate lateral buds. ood compact and tough. Buds appear to be better pro- tected from weather than maple.” The drawing, if not the de- scription, would indicate that the maple is Acer dasycarpum. For the next field work each member of the class was requested to make a study of the last year’s growth of a branch of each of two kinds of Acer. What is Acer? was one of the first ques- tions each member answered for himself. This lesson brought out the specific peculiarities of members of the same genus peculiarities not easily found in books within the reach of stu- dents. One of the first duties of a teacher in natural science 1S to keep students away from printed descriptions. They must go to the objects and make their own descriptions. I quote again from the first paper : “The bark of No. 1 is of a lightish color and it is difficult to tell a year’s growth, while that of No. 2 is of a red color and it is very easy to recognize a year’s growth, as there is a marked difference in the color. The coverings of the buds of No. rare much more scaly than those of No. 2, and they are also more me closely attached to their buds than those of No. 2 are attached . to their buds. The internodes of the first are much shorter than _ thoseof the second. The year’s growth of the first is shorter os than that of the second, as it grows moré slowly.” = Mauch better work than this is found on several papers.

This was followed by a study of two species of Pinus, which brought out the characteristics that pertain principally to branches and their leaves. The study of the evergreens being disposed of, in of course only a general way, the class took as a single field ex- ercise the following: Make a study of a branch bearing thorns and of another bearing prickles. It would be a pleasure to reproduce here the descriptions on a dozen papers, but already these notes are far longer than they were expected to be at the outset. Here is one, however : “No. 1 has large spines or thorns situated just above the lat- eral buds. These thorns are branched, having small thorns very two stems are to be of the same diameter.

These are chiefly found among Pyralids, and it is not necessary for my present purpose to refer to the cases in detail. For some years now I have been studying the remarkable life- habits of the Aphididz and especially of some of the gall-making and leaf-curling species of Pemphiginz. In the collecting of material and making of. observations, I have been assisted by Mr. Th. Pergande, who has on a number of occasions, since 1880, found the larva of this Fenesica associated with various plant-lice. Among the species with which it has been thus found associated are Pemphigus fraxinifolii Riley, which curls the leaves of F raxinus; Schizoneura tessellata Fitch, which The frequency with which this larva was found among these plant-lice justified the suspicion that it feeds upon them or derives benefit from them; yet up to 1885 the presumption was that it benefited from the secretions of the plant-lice rather than from the insects themselves, Last fall, however, Mr. Pergande obtained abundant evidence that the Fenesica larva actually feeds upon the Aphidids, and I thought it worth while to call attention to this Positive proof of the carnivorous habits of the species. That the different rendered more than probable for the following reasons: I.

Contrary to the usual way in Hemiptera, these males undergo complete metamorphosis. The waxy coat of the female consists not of the larval cuticles that were shed, but of variously crumpled and felted wax filaments emitted by dermal glands, and enclosing the re- mains of the cuticles. The embryological development is much as in Aphides, but the eggs have no pseudo-vitellus. Some notes on the Chermetidz are appended to the article, es- pecially on Chermes abictis and on Phylloxera. He kept the galls of Chermes, in autumn, till the parthenogenetic females escaped, of two varieties, some yellow, others nearly black. The female oviposited on the needles of a pine-branch in a heap. After this operation the mother died, protecting the eggs with her shrunk body and wings. In spring large wingless females were found on the pine-shoots, having remained over winter. Each had thirty to forty egg tubules, with two to four well-formed eggs; and the eggs had a pseudo-vitellus. The eggs were laid in masses at the base of the young pine-shoots ; the masses of eggs being covered with wax and with the carcass of the mother. The young issuing from these eggs moved to the axils of the needles, and together formed the nucleus of a cone-like gall; by their sucking the needle swells, coalescing with the gall. It is not the swelling of the needle, but of the branch that causes the gall; and this is due to the piercing action of the larvæ, not of the mother—G. Maclosnit. ` ao think the tænidia invariably form a continuous spiral thread. “P ~- the axils of the branches we see short spindle-shaped taenidia; ”» In certain Nne trachez of the eyes of the fly no spiral threads are developed, ous it may be called a senidium ; when only separate rings ree developed they may be called tenidia. I think, however, that F have demonstrated the nuclear origin of the “ spiral thread, an _- that the elongated filamental nuclei of the endotrachea coalesce a to form the spiral senidium.—A. S.

Dr. Geo.

[June, the investing sac bursts and a countless host of germs is poured forth. The growth of these germs into forms like the parent was continuously watched, showing gradual enlargement and ulti- mate, but as to time somewhat uncertain, appearance of the nu- cleus, and the somewhat sudden appearance of the flagella or thread-like motor organs, the latter being found in each instance to arise in the nucleus. Very soon after the adult stage is reached the act of self-division commences, and is kept up for hours in succession. The delicate plexus-like structure becomes aggre- cation of division of the body-substance. Quickly afterwards the nucleus becomes completely cleft, and the body-substance follows suit. Then the plexus-like condition is again diffused equally over the whole nucleus. When the generative condition 1s ap- proached by the last generation of a long series of dividing forms, it is remarkable that the organism becomes amceboid, showing such forms touch one another, they coalesce and fuse into each other almost as though two globules of mercury had touched, until nucleus reaches nucleus and two melt into one, and the blended bodies become a globular sac, which ultimately emits an enor mous number of germs. Previous to the blending it is now made out that all traces of plexus-like structure are lost in the nucleus, After giving similar details about several other organisms, es Dallinger summed up thus: “One thing appears clear, the 2 cleus is the center of all the higher activities in these (oe The germ itself appears to but an undeveloped nucleus, accomplished.

Leydig says that a blue granular pigment is rarely found in animals; in the crayfish, for example, there are blue crystals. The blue color is more often due to interference, owing to the presence of lamellæ, or to the fibrils of connective tissue, as in the tapetum fibrosum of the eye of ruminants ; the corium of the living larva of Pelobates fuscus -is similarly blue. A dull material overlying black pigment pro- duces blue, as in the case of blue eyes, which are due to the urea shining through the non-pigmented iris, andin some frogs. Dark chromatophores have a like effect, as has too the swelling of the corium consequent on the filling of the lymph-spaces. In conclu- sion, the author discusses the tegumentary secretions, which are of various colors, and which can be washed away ; an example is to be seen in the celestial blue color of the abdomen of Libellula de- fressa and, perhaps, the “bloom” of the pupa of the Apollo but- terfly. On the other hand,the coloring matter may be in cells of the epidermis, as is the case with the rosy color of Tetrao uro- gallus, and can then, of course, only be removed after the de- struction of the tissue which contains it— Journ.

Kowalevsky con- = ludes that the development of Dentalium has a good deal in common with that of the Lamellibranchs, the segmentation resembling that of Unio as described by Rabl, and Teredo as described by Hatschek. The segmentation is nearly regular, and eads to the formation of a hollow blastula and an invaginate gas- trula. The mesoderm`is derived from the inner wall of the invagi- nated side of the blastula, and the mesodermic cells are disposed symmetrically on either side of the median line. The shell-gland becomes defined very early on the dorsal aspect of the embryo, and as the blastopore travels forward, as in Patella, the area of the shell-gland, or mantle-organ, becomes greater, so that it gradually embraces the body of the embryo, especially over the region just behind the foot, leading to the development of the characteristic tubular shell. The resemblance of the larve of Dentalium to those of the Annelids is shown to be only a very superficial one. Three ciliary girdles encircle the anterior or cephalic pole of the larval body. The blastopore is wide at first, and persists as such much longer than in Patella; it is also elongated in the process of shifting towards the ventral, anterior aspect. A radular sac s developed on the inferior side of the cesophagus.

By division of the lower cells there arises a third layer of four inter- mediate cells, and soon after these four others appear which are apparently derived from the four upper ones. Thereupon six more smaller cells are developed at the animal pole, and somewhat later eight more such appear at the vegetative pole, so that the embryo is now composed of thirty-six cells. At this stage the gastrula mouth begins to develop; at first, as a slight depression, which later becomes deeper, leading to the formation of a sym- metrical gastrula consisting of ecto- and endoderm. The two annuli or cycles of large cells, which represent the velum, are now differentiated The gastrula is next somewhat elongated, and near the blasto- pore an endodermal cell is pushed into the blastoccel to give rise to the mesoderm. The blastopore is soon displaced somewhat ventralwards, and simultaneously certain ectodermal cells are drawn inwards to form part of the wall of the cavity of the gastrula. There are two distinct, symmetrically disposed groups of mesoder- mal cells near the blastopore ; the largest of these cells still form e endoderm and take part in limiting the cavity of the gastrula. The blastopore is gradually shoved nearer to the velum, and in connection with it is developed, an cesophagus formed 0 ectodermal cells. The mesodermal cells have multiplied, but re- tained their bilaterally symmetrical position. eae The cesophagus is now a spacious sac, from the posterior, 1n- ferior wall of which a radular sac has been invaginated.

In the anterior part of the body, the mesoder- mal cells form a gelatinous connective’ tissue between the organs. The pedal gland is now very strongly developed; its secretion is poured out between the ectodermal cells, a special opening for it be- ingabsent. At the sides of the body, above the foot, a ciliated band is present, which marks the site where the branchiz will appear. At the level of the first dorsal fold, the eyes may be recognized. The larva now leaves the egg envelope and swims about by means of its velum, The calcareous spicules are still enclosed by their mother cells, but soon break through.

Above all, the affected grandeur of royalty amid decay and national poverty, these are all subjects which Mr. Lowell fully appreciates and describes with charming race. : : As to the population, Mr. Lowell says: “ Money being more important to the Corean official oligarchy than men, the amount of taxable property in the kingdom, represented principally by rice fields, is much more accurately known than is the number of its inhabitants. No census of the population is ever taken, the number of the houses alone being counted. The estimate formed recently by a Japanese paper is probably the nearest yet made to the truth. This estimate gives Corea 12,009,000 inhabitants. ; “ As for Soul, the aggregate of population, including both thecity proper—that is, the part within the wall—and the outlying suburbs, will probably not exceed in all 250,000 souls. The amount of ground covered is about ten square miles. But a city in the far east extends only in two dimensions, not, as with us, in three. Tokio, in Japan, with about 1,200,000 inhabitants, covers eighty square miles, ; “The fabulously large estimated populations of Chinese cities— as for instance, Canton—will, I think, on trustworthy census be found to have been greatly exaggerated.” THE RELATION OF ANTHROPOLOGY TO THE SCIENCE OF ong In the scheme of anthropology followed by the NATURALIST, t e science of mind follows hard upon comparative physiology. | this journal, as it would be in an academy or scientific association, ca the rule has been to allow only those psychical inquiries to enter _ of all proportion to what we should be led to expect ° ape _ The spirit of such inquiries is rather to defy explanation perro _ promote it; they delight to nonplus and puzzle the scientific ! __vestigator, who is working his way upward by slow steps a of higher mysteries.

Taken in snatches, it appears in several places; it would come in under zodlogy, which embraces all that relates to animals; under physiology, in connection with the nervous system and the senses; and it figures still more largely, although in an altogether subordinate and scarcely acknowledged fashion, in the section on anthropology. Indeed, to exclude it rom this section would be impossible; man is nothing without his mind. “Now, while zoology and physiology would keep the study of mind within narrow limits, there is no such narrowness in the present section. In the ample bosom of anthropology, any really valuable contribution to the science of mind should have a nat- ural place. “ Psychology has now a very large area of neutral [non-contro- versial] information; it possesses materials gathered by the same methods of rigorous observation and induction that are followed in the other sciences. The researches of this section exemplify some -~ of these. If these researches are persisted in, they will go still further into the heart of psychology as a science, and the true course will be to welcome all the new experiments for determin- reference to our sensations; the whole of the present mathematics | of man, bodily and mental ; the still more advanced inquiries re- lating to our intelligence ; and the nature of emotion, as illustrated by expression, in the manner of Darwin’s famous treatise.

Among the relics were four heavy perforated stone (probably serpentine) disks, measuring from four to five and a half inches in diameter, and still retaining _ their handles of zoygn or bearberry-wood, which is among the hardest in Southern California. The handles are from thirteen to seventeen inches in length, and are cut off bluntly. To judge from an accompanying photograph, the stones are in every way analogous to a certain class among the many perforated stones collected by Mr. Paul Schumacher and others in the same neigh- borhood, and now in the archæological collection of the National Museum. Dr. Rau expressed ten years ago (in “Archæological Collection of the U. S. National Museum,” p. 31), the opinion that the more bulky of the Californian disk or cone-shaped stones served as club- heads, and he was strengthened in his view by the fact that the „extensive National Museum collections from the above-named t theory would be so unexpectedly verified by the finding of such stones with their handles still inserted.

STRUCTURE OF THE Human Sxin.—The following note refers to a method of isolating the epidermis of human and other embryos from the underlying dermis, and to the presence of a layer of cells, not previously described, which may be observed in the epidermis when so prepared, and which corresponds, I think, to the epitrichium of birds. The method is also convenient for the study of the development of hairs. It is well known to physicians that if the foetus dies and is retained, it is preserved for a considerable period without disinte- gration of the tissues in the amniotic fluid. In specimens thus Preserved it is often found that the epidermis is loosened so much that strips can be removed without tearin g off the underlying tissues, Ow as the amniotic fluid is little more than a salt solution, the facts just stated naturally suggest that a salt solution preserved from septic changes is sufficient to loosen the epidermis of the embryo.

Some time in the latter part of May or early part of June, 1835, Mr. Merritt, of Pittsborough, N. C., brought to Chapel Hill two trap-door spiders with their nests, and placed them in the care of Professor Holmes for the University of North Carolina. The nests with their occupants were placed in the ground for the summer. On Nov. 12, after a careful search, Professor Holmes =| was able to find only one, and this one with difficulty, as for some reason it had dug through the lower end of the tube and was hidden in the earth. Later I shall offer what seems to me may be an explanation of this. On the morning of the same day the spider with its trap-door nest was placed in my keeping, which a was the first intimation I had of the presence of such an agree- mS able neighbor. 3 At 4.30 p.m. I placed three and a-half inches of earth ina glass hy jar five inches in diameter and seven inches deep. Two-thirds of the surface of the soil was then covered with moss. In this the af spider was placed, and the jar and its contents taken to er : room, that I might, if possible, observe the operation of digging l the tube and making the trap-door. The results were most gratifying. Just before going to supper, at dusk, I observed that the spider had not undertaken the work. aes -Upon returning, at 8.30 P.M., I found the task undertaken. The bye spider was resting in a hole about 20" deep by 22™ in diame- ter, which she had excavated at one side of the jar. I placed the jar upon my study table, just beneath the light of a student lamp, so that while reading I could observe any movements made by my companion. The spider was resting in the hole with its legs pat tially folded, the anterior ones lying upon the edge of the exc vation. After I had been quiet for some time the spider began to wget cautiously, and turning about slowly went head first into d : oe hole, and dug from the bottom with her mandibles a eee . _ earth about the size of a small pea.

During the course of the evening three to 1886,] A new Trap-door Spider. 585 persons, who came to my room, had the fortune to witness the operation of digging out the earth. The spider soon became bold, paid no attention to movements in the room, and permitted me to watch her very closely. Occasionally, by using both palpi at once, the dirt was flirted suddenly from the grasp of the man- ` dibles with such force as to strike against the opposite side of the jar. Had it not been for this obstruction the dirt must have been thrown three or four feet. After depositing each load on the edge of the hole, the spider would turn around again for another load, but before picking it up she would project the posterior pair of spinnerets about 5™™ from the abdomen and carefully knead the viscid liquid upon and _ around the freshly placed pellet of earth and over the edge fora distance of 4 or 5™™ for the purpose of making the soil adhere and prevent its caving in. In Plate xxii, Fig, 4, the spider is shown in the act of removing a pellet of earth from her mandibles. In Fig. 5 is represented the application of the viscid liquid. The ends of the spinnerets are applied to the surface alternately, as shown in the illustration. The legs took no part in the applica-_ tion of the viscid liquid; nor did the liquid form a thread when the spinnerets were drawn from the surface, as I have since seen | it when the spider was crawling about on the surface of the > earth ; oo * 3 As I am now writing, Jan. 16, 1886, 11.55 P.M., the spider is crawling bo ton the surface of as about the earth are loosely matted together in the path of the spider about the — 586 A new Trap-door Spider. [July, on the under side of the partial door, she would carefully move it up to the edge. Then placing the distal portion of the palpi and anterior pair of legs above, while the proximal portion of these limbs and the ends of the mandibles were on the under side of the pellet and door, she would fit and press it in shape, as one would mold with the hand a moist portion of earth by press- ing it into a thin sheet. This is illustrated in Fig. 7, Plate XXIII. Indeed it looked very much like the black bony fingers of a hand performing the work of pressing. The greatest pressure seemed to be brought to bear upon the rounded ends of the mandibles. After fastening on a portion thus, the spider would take an in- . verted position and apply viscid liquid along the edge and under the surface of the door, as shown in Plate xxii, Fig. 6. She would then turn about and crawl out for more material. The hole being by the side of the jar, I could watch the operation both in the hole and upon the cover. By one o’clock in the morning (Nov. 13) the door was finished so that the spider could pull down the lid, which completely closed the entrance, nicely fitting - in around the edge and appearing as if there was no hole nor spider, but through the glass the spider could still be seen. At intervals during the construction of the door the spider would pull it down to observe where the next pellet should be placed in order to make the door fit the circular opening of the tube. Discovering this she would turn completely around, and not being able, with her head in the bottom of the tube, to see the place where she intended to put the next load, she would find ; it by feeling about with her spinnerets. The viscid liquid would then be applied and the pellet of earth fitted with extreme nicety» Satisfied with the result of my experiment I retired. By day- break I found that the excavation was continued after the com- ~ pletion of the trap door, the soil being deposited around the nest to raise the surface of the earth in the jar to a level with the top of the nest. Without close searching it was impossible to detect _ the door. = — The mode of making the trap door by this spider differs very _ widely from that observed by other naturalists so far as Iian als, construct a trap door in captivity.

The trap door at this stage resembled a rudely constructed, horizontal, geometrical web, attached by two or three threads to the earth at the mouth of the hole, while in this web were caught the bits of earth, roots, moss, leaves, etc., which the spider had thrown into it from above. After the sec- ond night the door appeared nearly of the normal texture and. thickness, but in no case would it open completely, and it seemed the spider was too much disgusted with her quarters to think it worth while to make a perfect door.” He also records the making of a door by a very young one of thi so that the door would open and shut? The only: thing he records which seemed at all analogous to the mode of making a trap door exhibited by the spider in my Possession is that manifested in the enlargement of nests and trap doors by Spiders as they grow larger, and consequently require nests of larger dimensions, This operation was not witnessed by him, however, but the additions to the size of the door were Proven by measurements and observations upon nests of young spiders at different seasons It would seem natural to suppose that in making slight addi- tions from time to time to the edge of the nest, the spider would cement pellets of earth, pieces of moss, etc., to the edge instead of first spinning a web ; unless the web is spun over the lower side of the door and made to project just far enough to fit the en- larged tube. In Plate xxi, Fig. 8, can be seen eight concentric “lines of growth,” as they might be termed, of the trap door, corresponding to the growth and needs of the spider. These I Judge to represent the successive enlargements of the door con- mitant with the enlarging of the tube.

There is no Such regularity. Indeed, this last door was made of about a dozen very large pellets of clay which, being very plastic, the spider was able to press each pellet into a sheet of considerable dimensions, It is to be regretted that Mr. Moggridge did not have the opportunity of observing the manner of enlargement of trap doors made by the spiders which he studied, or that he did not offer some theory as an explanation. If the particles are cemented to the edge, it would be quite natural that the species of spider in my possession once made its door by first spinning a web across the mouth of the tube, and then weaving into it other material, as in the case of N. meridionalis, and that the habit, followed through life and successive generations, of making additions to the door by cementing particles to the edge, finally became so fixed that this mode of making additions to it became the permanent habit ~ — and type of construction of the trap door from the foundation! T -The rapidity, ease and intelligence manifested in this method of ~ building up the door, piece by piece, certainly indicates a higher development of instinctive power. A perfect and neatly fitting and swinging door made in 1% hours! _ When I took the spider from her nest it was necessary to -remove nearly all of the soil from the jar and take her from the lower end of the tube, as all efforts to attract her from the nest failed. As the soil was very loose and the nest not long made, the walls of the tube collapsed. In ten days the spider was ~ returned to the nest. Though the trap door was capable of being _ used, and seemed to satisfy the spider’s idea of the * fitness of things,” it was in a very dilapidated condition. This agrees with ` what Mr. Moggridge says of the reluctance manifested by gee = to abandon an old nest. The examples cited by him are, B _ adoor be pinned back during the night, a second door will be _ made; that if the nest be covered with earth, the tube will be oh prolonged to the surface of the superimposed earth afid a new ~ trap door will be made; and that in some cases nests become 10- verted, when a door being made at the now uppe f tube, the nest will have a door at each end!

This, with the spider in it, I placed in the glass jar and surrounded it with earth to darken the walls, hoping thus, because of the firm smooth surface of the tube, she would not line it with silk, and by lifting the tube from the soil I could ob- Serve the position of the spider as it held down its door. The experiment was a decided success. This was prepared at eleven o'clock on the night of Dec. 27 '85. Pieces of moss were strewn about the tube. By morning a perfectly fitting door, beautifully covered with moss, had been constructed (Plate xxiv, Fig. 3). About this time many visitors came to see the spider, and in pulling at the door to show how persistently she would resist its being opened, the hinge became, loosened and the door was pulled down upon her. She held on to the door with such tenacity that I pulled it into bits in my efforts to remove it from her grasp. It was removed Dec. 30, 85, and on the following night she built another as neatly as the first. The hinge to this became loosened and the door moved down about 5™™ from the mouth of the tube. Here she strength- ened the hinge by Spinning a broad piece of silk, the width of the hinge, from the door down on to the wall of the tube. Several times in endeavoring to open the door I tore pieces from its edge, and in every instance the spider repaired it. Finally, when I Wished to remove her from the tube I was obliged to push up on ; the cork bottom, and in this way crowd her out through the door. = Akter this was done it was with some difficulty that she freed her Posterior feet from the silk bag which she had constructed at the ottom, so firmly did she hold on. a fa I have this yet to add. Ina note I have mentioned the wan- dering of the spider about in a jar of freshly prepared earth, Jan. 16. For three days she has been restless, and though several - attempts have been made to dig a tube she had failed. I came to °r satisfactorily. Wishing to have soil which would make a more , I used a large proportion of fine plastering sand mixed with 590 A new Trap-door Spider. [July, earth, but seemed to be disgusted with its crumbling. She then tried to bore a hole by pushing down with her mandibles while turning her body around. She evidently wished to hide her head from the light, for after making a hole 2™ deep she remained with her head at the bottom. To-day, Jan. 14, ’86, the soil in the woods having thawed sufficiently, I prepared a jar of moist fer- ruginous clay, very much like that of which the nest is con- structed that came from Pittsborough. Upon this I puta fine mat of fresh moss, covering the earth except a spot at one side 2%4™ in diameter. In this I placed the spider at noon. I then covered it from the light. As I returned to my room after din- ner, she was resting in a hole 3° deep which she had excavated, and small pellets of earth were placed against the moss at the mouth of the hole. She would not work during the day unless I covered the jar from the light. During the evening, by lamp light, I had the pleasure of seeing her make another door. It required about one and a half hours, Only one piece of moss was used, and that I let drop into the hole while she was at work. This seemed very strange, for the tube was the only place not covered with moss, and to save her the trouble of cutting the moss I had strewn loosened particles about the hole. In this case all of the earth used in the construction of the door was taken from the bottom of the hole. The door being made almost entirely with the clay was very conspicuous in comparison with the surrounding moss; though the door fitted very neatly, the tube being built up to a level with the top of the moss. This _ time instead of making the hinge against the side of the jar 5 was made on the opposite side of the tube. Surely this persist- ence is equal to that shown by the spider who, making her w the thirteenth time, taught a general lesson of perseverance. ~ Iwas unable to understand how the resistance to opening tt _ door was offered, if the spider fastened its fangs and all of its _ claws into the under surface of the door, as Mr. Moggridge cS states! A reference to Plate xxiv, Figs. 3 and 4, will show ee the _ tion of the tube from å to c was not lined with silk. The spider evidently not admiring the cork at d for a bottom to carried in pellets of earth and bits of moss as shown at & : 2 * Harvesting Ants and Trap-door Spiders, pp- 95-96. 1886. } A new Trap-door Spider. 591 then spun a short bag of silk, 4 which was attached by the mouth to the walls of the tube at c, and rested on the piece of of cork. The mouth of the test tube was lined with silk from the edge for about 5™™ to 7™™- The ends of the silk lining at 4 and the silk bag at c were for some distance transparent, so that I was enabled to see the spider fairly well. As can be seen in Fig. 4, the spider clings to the bag of silk at the bottom (or walls of the tube) with the claws of her two posterior pair of legs, and to the under surface of the door with her fangs and the claws of her anterior pair of legs. By partially lifting the door I was enabled to see the hold upon the door, and when I pushed the spider out of the tube, as before stated, I found her feet entangled in the bag of silk. The manner in which this spider holds down the door is precisely the same as that described by Emerton! in the case of Cteniza californica, except that he states the “ third and fourth pairs of legs are pressed out against the walls of the tube.” The nest of this spider belongs to the simple, unbranched type with shallow cork door. The door belonging to the nest in which the spider was caught (Plate xxiv, Fig. 1) measures 3 to 4™™ in thickness; the edge is beveled and fits neatly in the mouth of the tube. The door measures 25™" across near the hinge; the tube 60" in length. The walls are badly collapsed, and the lower edge ragged and open. It will be remembered that the spider was found in the earth below the tube when the nest was taken up in November. The first nest which the spider made under my observation was left open at the bottom, and when I the tube. The question naturally arises, Is this not left open as is, in some cases at least with this species, as this is the only needed on this point.

While I had the spider out of her tube I offered her several house-flies, holding them by one wing with the forceps near her head. The struggles of the fly attracted her attention. - With a quick sweep of the palpi and anterior pair of legs she would clutch the fly and place it between her powerful mandibles, crushing it immediately. She held some of these about one minute, but I very much doubt her having derived any nourishment from them. One of the smaller species of the flies belonging to the genus Tabanus was offered her. It seemed only to frighten her, as she could not be made to touch it even by being angered, but would turn and run away as if in great fear. After returning the spider to her nest, Dec. 8, I placed in the jar two ants and a small carabid beetle. The ants hid themselves in the earth. Dec. 14 the beetle was still unharmed, and I concluded the spider did not come out for food. I then lifted the trap door and placed the beetle inside. Dec. 16 I found the broken hard parts of the beetle strewn about _ just outside the nest. It had been killed, the soft parts eaten by ae the spider, and the parts of the skeleton ejected from the nest. à Jan. 17, ’86, I placed a half dozen large yellow ants in the jar. _ As they attacked her she would catch and crush them, but I did ‘not see that she ate any of them. : Noe Jan. 2,’86, which was almost like a summer day at Chapel | Hill, I went into the woods for the purpose of collecting some moss. While tearing up a large patch of this at the foot of a tree, I discovered a hole which I thought to be the nest of a trap- = door spider. I dug down into the tube and found at the bottom = a spider belonging to this family. In the afternoon I fou: * sev- _ eral nests and one more female spider. Under some stones I _ founda male.

BY JOHN MURDOCH, * in what is now the territory of Alaska, there is one legend, that - Greenland tradition (p. 237), and from this draws additional evi- dence of the identity of the Eskimo race over this extensive The following fragments of stories were collected by the writer _ A description of these spiders I reserve for a future time when a fuller collection 1s made and habits more clearly observed. sae a 594 A few Legendary Fragments from [July, and other members of the United States International Polar Ex- pedition from the Eskimos of Roint Barrow, Alaska, which is the extreme north-western point of the continent of North America, _ during a stay of two years (from 1881 to 1883). The fact that several of them show features indicating a relationship with well- known Greenlandic stories seems to the writer to render them, scanty as they are, worthy of publication. Two or three of them have already been published by Lieut. Ray, the commander of the expedition, but as they appeared in a government publication,’ perhaps not accessible to all readers, it will not be out of place to repeat them here. Occupied as our party was with the manifold routine scientific work of the station, it was exceedingly difficult to get hold of ‘ any of the traditions of the natives, though they showed no ; unwillingness, from superstitious or other reasons, to talk freely about them. In the first place there were so many (to the Eski- mos) more interesting things to talk about with us, that it was a difficult to bring the conversation round to the subject in ques- . , tion. Then-our lack of familiarity with the language was a great hindrance to obtaining a connected and accurate version of any story. The jargon, or kind of Zingua franca, made up of Eskimo : roots and “ pigeon English ” grammar, which served well enough = for every-day intercourse with the natives, enabled us, with the ae help of expressive gestures, to get the general sense of the story, _ but rendered it impossible to write down an Eskimo text of the tale which could afterwards be translated. Moreover, the confu- ; sion and difficulty was still further increased by the fact that two == Or three people generally undertook to tell the story at once. , In writing out the following stories I have endeavored to avoid __ introducing ideas and expressions of my own, and to ad 5 closely as possible to the simple sense of the brief disco -~ sentences of the narrators. =I. How people were made. Long ago, Aselu, a dog—“ where _ he came from I did not hear ”—was tied to a stick. He bit the _ stick [7. e., set himself free] and went into the house, where he had intercourse with a woman, who gave birth to men and dogs: here as nnected The belief that a dog was one of their remote progenitors is a very common one among savages. According to Egede (Green: ae to Point Barrow» inate: 2 Report of the United States International Polar Expedition i RENE By P. H. Ray. Wa: ni 88 Š. y 1886,] the Foint Barrow Eskimos. 595 land, p. 195) the Greenlanders believed that white men were the offspring of a similar union between a woman anda dog. (The same story is also referred to in Rink’s “ Tales,” &c., p. 471.) i 2. Another account of the origin of human beings. In the east, a tall tube [like a reed. The narrator to illustrate this pointed to one of our bamboo fishing-rods] stuck up from the ground. A man broke the tube. “ Behold, ‘many men and women!” i 3. The origin of reindeer and fishes. Both reindeer and fishes were made by a mythical person of whom we got only a vague account, though he was often mentioned. He was said to be a little man with long tusks like a walrus, and many of the little Eskimo figurines and masks of ivory, soapstone or wood, which we brought home from Point Barrow, represent such a being, and are, perhaps, meant for images of this person. When the deer was not, this man made one out of earth. The deer all had large teeth in the upper jaw and were “ bad ”—they bit people. So he said to them: “Come here!” and when they came he pulled out these teeth. Now they are “ good.” The reindeer, of course, like the sheep and other ruminants, ; has no incisor teeth in the upper jaw, and this myth is certainly an ingenious way of accounting for this fact, which must have Seemed very strange, since all the other animals known to the Eskimos are well supplied with teeth in both jaws. on the fish were not, this man hewed a piece of wood by € river side with his adze. The chips fell into the water and were fishes ere seems to have been a similar myth in Greenland. Ac- _-- ording to Crantz: “ They say fishes were produced by a Green- lander ! P. 204); and Egede tells a similar story (Greenland, p. 196). but the natives know what these phenomena are and account for them as follows: ip into the sky, carrying a dried sealskin and torches of tar. With _ the to ze rches and rattling the sealskin.

It rarely thunders at Point Barrow, Long ago a grown person and a child went up | ; : sse they make the thunder and lightning, apparently by waving (July, gives a version slightly different but agreeing in the main with 596 A few Legendary Fragments from is. Evidently related to this is the Greenland tradition referred to by Crantz (Vol. 1, p. 233) that the thunder is caused by “two women stretching and flapping a dried sealskin.” Egede (p. 207) gives the story in greater detail. The thunder and lightning are made by two old women who live in a house in the air. They now and then quarrel about a dried sealskin, and while they are fighting down comes the house and breaks the lamp, so that the fire flies about. 5. The story of the Kokpausina. Long ago there were five very strong brothers, Kokpausina, Kokkaun, Inaluoktuo, Nimna and Pakanigarua. (The narrators were particular to impress It upon us that these men were not especially tall, but very stout and strong. The strength of Kokpausina especially seems to have become proverbial, for an Eskimo once compared the great, pow- erful hand of an old whaleman, one of our party, to that of Kok- pausina.) Kokpausina lived at Pernye [7. e., “the elbow,” the summer campground in the bend of Elson bay, between Point Barrow and the station], Kokkaun east of Point Barrow on the seashore, Inaluoktuo inland in the south, Nimna at Dease inlet, and Pakanigarua at Cape Smyth. Kokpausina found two little a orphans asleep and thrust excrement up their noses [apparently be from sheer malevolence, though we never succeeded in making the natives understand that we wanted to know the reason of this action.] So they went home and made a little bow and = arrows, short enough to hide under the jacket, but strong enough to shoot through a walrus-hide dried before the fire [and there- _ fore nearly as hard as iron]. Then they went to Pernye and saw = Kokpausina, with his back towards them, stooping OV¢r they shot him in the buttocks and the arrow came out at his - Tar bone, and he died. His great shoulder-blade and some of his other bones are still at Pernye. [Natives who came down from the Point Barrow i Tage to the station once or twice told the writer that they hae seen Kokpausina’s bones at Pernye on their way down went so far as to bring us down a rather large human jaw mae from the old cemetery near Pernye, saying that it was Ko! _pausina’s.] col- : This story, which we heard from several narrators without any - ee the Point Barrow Eskimos. 597 essential variation of names or incidents, and without being able to get more details, is the skeleton of one of the semi-mythical traditions so common in Greenland, which may really refer to ` some actual occurrences in ancient times, but which have been localized and adapted to suit the region in which the narrator ives. ~ The death of Kokpausina bears a strong resemblance to the `“ final catastrophe of the Greenland story of Kagsuk (see Rink’s “ Tales,” &c., p. 431), which is said to have taken place in Green- land, in the districts of Holsteinborg and of Sukkertoppen, and according to Dr. Rink is perhaps a variant of an older tale only localized in this: way. In this story the wicked Kagsuk, after committing various deeds of violence, at last murders the sons of two old men “clever in magic spells.” To revenge themselves they prepare “ bows of an arm’s length,” and while others engage Kagsuk’s attention in front they creep up behind, escaping obser- vation by magic, and shoot him dead. It seems hardly too bold a statement to say that if Kagsuk and Kokpausina were real persons at all they were one and the same man, who lived neither at Sukkertoppen nor at Pernye, but some- Where in the common home of the prehistoric Eskimos, before the Greenlanders started on their weary journey towards the east and the men of Point Barrow on’ their perhaps longer journey _ towards the setting sun. : It is interesting to note that the five very strong and (appa- tently) wicked brothers who appear in this story are evidently € same as the “band of five brothers, generally called ‘a lot of’ brothers or men ” who, according to Dr. Rink, figure in so many of the Greenland tales as the personification of haughtiness or ee brutality, ne E EEE ee | ee ae ee a ges PE pi : 6. A murder at Cape Smyth. Udlimau was once given as the name of one of Kokpausina’s four brothers, but the narrator afterwards corrected himself and said, as did other natives also, that Udlimau was a bad man who long ago lived at Utkliavwing (Cape Smyth) and who murdered Kumnero as he lay asleep be- i his wife by cutting him across the bowels.

Long ago, when there — 598 Legendary Fragments from the Point Barrow Eskimos. {Juiy, was no iron, five families had their houses at Isitkwa (the site of the signal station, where several mounds indicate the position of the former village). They were called Isitkwamiun (“they who live at Isatkwa”), and they talked like dogs. “They said “imek- lunga, wa! wa!” (“I want a drink, bow-wow ba The following fragment, however, for which Lieut. Ray is my authority, and which was also related to Dr. Simpson thirty years — before, which both these gentlemen think indicates that these Eskimos are really acquainted with an unexplored land in the north, is in my opinion more probably referable to the same cate- gory as the numerous tales of the eastern Eskimo about the mythical land of Akilinek. 8.

We also heard of various fabulous animals, though in many cases the names which in Greenland are applied to animals known only by tradition, and which therefore have grown into fabulous monsters, are still used for the animals to which they properly belong, as in Labrador and elsewhere, for instance, 4747? me ~ the wolf, and avwinga the lemming, while in Greenland the ama- ~ rokand avingak are semi-supernatural creatures that figure # many of the old stories. i _ The Greenlandic word filivfak or hiliopak, which there means an animal with six or even ten legs, appears.at Point Barrow 3 _ atthe Mackenzie river in the form 4i/igwa as the name Hass mammoth or fossil elephant (see also Rink, “ The ese lects,” Journal of the Anthropological Institute of Great Britain, _ November, 1885). We heard none of the fanciful myths coca this animal which have been reported by various travelers the shores of Bering sea, but the word was in common US® espe cially as the name of the fossil ivory, which is very plenty much used by the western natives for various purposes. - l 1886.] It is interesting to note in this connection that one of the little ivory images brought home by our party from Point Barrow rep- resents a bear with zez legs, said to have been seen once at Point Barrow, and evidently a blood relation of the many-legged 4iliv- 4 fak of the Greenland stories. 4 Another fabulous beast was the ugruna. “ There are none now on the land. It has gone away, only the bones [remain].” This name appears to be applied to an extinct species of ox or buffalo, whose bones they sometimes see in the interior, probably along the banks of the rivers. We procured several teeth of the ugruna which had been worn as amulets. As in Labrador this name is also applied satirically to the smallest mammal known to the Eskimos, a little shrewmouse. As elsewhere on the American continent, the Red Indian, who in Greenland, like the wolf, has become a fabulous being, dwell- ing in the mysterious inland country, is called by the contemptu- ous name, “son of a zz” —Itkidling, the Ingalik or “ Ingaleet” of Norton sound, which is plainly the same word as the erkilek of the Greenland traditions. . Outside of the strict field of legendary history or tradition, th Teligious ideas and superstitious observances of these people, as far as we had the good fortune to observe them, show a great resemblance to those of the Greenlanders before their conversion to Christianity. So strong is the resemblance in this and in other respects that I feel confident that an intelligent observer who should devote himself to the collection of the traditions of the Eskimos of Point Barrow, as Dr. Rink has so ably done for the eae a ee ee ions of the Greenlanders in a recognizable shape. 202 HISTORY OF CELERY. ing of Cultivation so as to embrace selection and the cross-fertili- | VOL.

One fact, however, through careful observations, seems undoubtedly true, that by selection alone, without the assistance of the break caused bya cross-fertilization, changes in our plant are extremely slow, and many generations are required to obtain and fix any change other than increase which is sufficient to be noted by the casual eye. In support of this view we can direct attention to the little change that has been produced by centuries of culture in those plants which represent but improved formis of a wild species, such as thes" parsnip, scorzonera, salsify, etc., among roots; and we may also call attention to the stability of type-form during centuries of culture in the eggplant, pepper, and I may even add the pump- ye kin. Perhaps one of the most interesting instances of increase -of size without change of type can be seen in the watermelon. The old herbalists figure this fruit of small size, but as is very likely, only small varieties were commonly grown in Europe. John Bauhin, whose history of plants was published in 1650, many years after it was written (he died in 1613), states the watermelon to be so large that one could scarcely embrace it with the two hands, “quos fere ambabus manibus ambias.” Marg- gravis, whose history of natural productions of Brazil was pub- lished in 1648, describes the watermelon as being as large as one’s head, “ magnitudine capitis humani.” That our present a types of fruit were then known is evidenced in many ways but can be given succinctly by Caspar Bauhin’s statement 1n his ; _ Pinax, edition of 1623, that some have a green skin, others 4 skin spotted with dingy white; the flesh of some red, of othes f white; the seeds black, red and tawny, in varieties. Ray de- scribes the fruit as round, or globose or even elliptical.

The celery has originated from the Apium graveolens L., a plant of marshy places whose habitat extends from Sweden southward to Algeria, Egypt, Abyssinia, and in Asia even to the Caucasus, Beloochistan and the mountains of British India} and has been found in Fuegia,? in California’ and in New Zealand.! It is supposed to be the se/inon of the Odyssey, the se/inon heleton of Hippocrates, the Aleioselinon of Theophrastus and Dioscorides and the Heloselinon of Pliny and Palladius. It does not seem to have been cultivated, although by some commentators the word interpreted as smallage has a wild and cultivated sort. Nor do T find any clear statement that this smallage was used as food, for sativus means simply planted as distinguished from growing wild, and we may suppose that this Apium, ¿f smallage was meant, was planted for medicinal use. Targioni-Tozzetti® says this Apium was considered by the ancients rather as a funereal or ill-omened plant than as an article of food, and that by early Modern writers it is mentioned only as a medicinal plant. This seems true, for in the books in my library I find that F uchsius, 1542, does not speak of its being cultivated, and implies a medic- imal use alone, as did Walafridus Strabo in the ninth century ; Tragus, 1552, likewise; Pinaeus, 1561; Pena and Lobel, 1570; also Ruellius’ Dioscorides, 1529; Camerarius’ Epitome of Mat- thiolus, 1586, says planted also in gardens, “ Seritur quoque in hortis,” and Dodonaeus, in his Pemptades, 1616, speaks of the wild plant being transferred to gardens, but distinctly says not for — food use, According to Targioni-Tozzetti,’ Alamanni in the six- feenth century speaks of it, but at the same time praises Alexan- S for its sweet roots as an article of food.

Bauhin’s name, Apium vulgare in- gratus, does not promise much satisfaction in the eating. Accord- ing to Bretschneider' celery, probably smallage, can be identified in the Chinese work of Kia Sz’mu, the fifth century A. D., and is described as a cultivated plant in the Nung Cheng Ts’nan shu, 1640. We have a mention, however, of a cultivated variety in France by Olivier de Serres in 1623 and in England the seed was sold in 1726 for planting for the use of the plant in soups and broths,’ and Miller‘ says, in 1722, that smallage is one of the herbs eaten in the spring to purify the blood. The cultivated smallage is even now grown in France under the name of Celert a couper, differing but little from the wild form. The number of names that are given to smallage indicate antiquity, such as Arabic Asalis, Italian apio, German Eppich, Spanish Ferexil dagoa, French ache’ Egypt Kerafs English smallage, etc. 7 The prevalence of a name derived from one root indicates @ Sk recent dispersion of the cultivated variety. Vilmorin’ gives the f ` following synonyms: French Celeri, English celery, German Sel- u leree, Flanders Selderij, Denmark Selleri, Italy Sedano, Spain apu, i Portugal Aio, and M’Intoshê gives for the Spanish Apio hortensis. E The first mention, of the word celery that I have observed is in ae Walafridus Strabo’s poem entitled “ Hortulus,” where he give a the medicinal uses of Apium, and in line 335 uses the word as follows : ae “ Passio tum celeri cedit devicta medele.” y, as it trans- as de- The disease then to celery yields, conquered by the remed may be liberally construed, yet the word celeri here may be lated quick-acting, and this suggests that our word celery W „rived from the medicinal uses. Strabo wrote in the ninth century, __ having been born A. D. 806 or 807, and dying in France in 849: ~ Targioni-Tozzetti® says it is certain that in the sixteenth century celery was already begun to be grown for the table in Tuscany: A cannot find any mention of celery in Fuchsius, 1542; Tragus, 1557?

Parkinson’s Paradisus, 1629, mentions Sellery as a rarity, and names it Apium dulce. Ray in his Historia plantarum, 1686, says the smallage transferred to culture becomes milder and less ungrateful, whence in Italy and France the leaves and stalks are ` esteemed as delicacies, eaten with oil and pepper. The Italians call this variety Sceleri or Celeri. The French also use the vege- table and the name. He adds that in English gardens the culti- vated form often degenerates into smallage. Quintyne, who Wrote’ prior to 1697, the year in which the third edition of his | Complete Gardener was published, says, in France “we know but one sort of it.” Celeri is mentioned, however, as Apium dulce, Celeri Italorum in Hort. Reg. Par., 1665 ;? in 1778 Mawe and Abercrombie note two sorts of celery in England, one with the stalks hollow and the other with the stalks solid; but in 1726 Townsend? distinguished the celeries as smallage, and sel- lery, and the latter he says should be planted “ for Winter Sallads, because it is very hot.” Tingburg* says celery is common among | the richer classes in Sweden, and is preserved in cellars for win- ter use. In 1806 M’Mahon® mentions four sorts in his list of : garden esculents for American use. It is curious that no men- 1 tion of a plant that can suggest celery occurs in Bodaeus and ligers edition of Theophrastus, published at Amsterdam in- 1644. : The summary of our investigation hence is, that we find no clear evidence that smallage was grown by the ancients as a food - = ` Plant, but that if planted at all it was for medicinal use. The — : first mention of cultivation as a food plant that I note is by Oli- à : vier de Serres, 1623, who calls it ache, while Parkinson speaks of celery in 1629, and Ray indicates the cultivation as commencing : lly and extending to France ‘and England.

Among the earlier varieties we find mention of hollow- stalked, stalks sometimes hollow, and solid-stalked forms ; at the present time the hollow-stalked forms have become discarded. Vilmorin! describes thirteen sorts as distinct and worthy of cul- ture in addition to the celeri a couper, but in all there is this to be noted, we have but one type. A curious circumstance is that smallage took on the appear- ance of celery before its use was commonly recorded, if at all, as a salad plant, as is evidenced by the drawings herewith reproduced in reduced form. The first drawing is substantially the same as that in Fuchsius, 1542; Tragus, 1552; Pinaeus, 1561; Tabernaemom tanus ic., 1590, or Gerarde, 1597, and Dodonaeus, 1616, and is taken from Matthiolus’ Commentaries, 1558; this represents the common expression of the herbalists as to the appearance of Apium palustre at this time. The second picture is from Came- rarius’ Epitome of Matthiolus, 1586, and represents the form we call celery, but hollow stalked as at first noticed.

[July, now some of our varieties, such as the Boston market, are of a very delicate taste, far different from the sort spoken favorably of by Townsend in 1726 as very hot and very slow growing. It is probable that some original variation in quality discovered in the wild plant suggested cultivation, for among a people like the Italians, with whom high aromatic taste seems popular, the strong savor of the smallage would present little objection, if only grateful to them; or that its use was suggested by some popular idea of its value as a medicinal food, as seems probable. That there is ‘great variety in wild plants in respect to flavor, we have every reason to believe. Smallage, described by most bot- anists as a suspicious if not dangerous plant for eating, yet in Fuegia was found palatable and healthful by the sailors of the exploring ships,! and in New Zealand described by Forster’ as truly pleasant and salutary for scorbutic sailors. The use in Italy as a medicinal food, and the introducing to garden culture, with blanching, etc., would improve the flavor and. increase. its use, and improvement once initiated and recognized would neces- sarily continue, and stability of type-form would also tend to continue, as the seeding habits of the garden plant is not favora- -ble to cross-fertilization with the wild or allied species, it being a biennial, and not usually seeding alongside of other species with which crosses might occasionally occur. We have now in celery an improved, not changed, wild p which does not now tend to revert to the wild form, as it see to have done at the first, and a good illustration of the fixity of a garden form species.

EVERMANN. URING two years spent in Ventura county, Southern Cali- fornia, I became quite familiar with this handsome yet noisy bird of plebeian tastes. The yellow-billed species seems to be restricted in its range to California, throughout which State it is locally abundant. ; i One of the great industries of Southern California is wool- growing; the valleys and hillsides are covered with flocks of sheep, from a score to several thousands in number; and nearly every cañon has its corral to which the herder and his faithful dog drive the flocks at eventide. Here they are shut up and guarded through the night. In the morning .they are again’ turned loose to feed upon the burr clover, alfillarilla (or “ fillareé ”), and such other stuff as can cause only sheep and mules to thrive. In and about these corrals are various kinds of filth—carcasses of sheep that have died of disease or starvation, bodies of dea lambs and the refuse of the sheep which the herder has slaugh- q tered for his own larder, for jerked mutton and tortillas constitute b the chief part of his meager bill-of-fare. Such a place as this is 4 à paragon of restaurants to the magpies, Here they can be found ‘in the early Morning, in the evening, and at any other time of day when they happen to be hungry. Here they come to feed upon the filth, keeping up an almost incessant chattering, crying and scolding, which if translated into intelligible English would certainly bristle with oaths and slang. For there, where the glish sparrow has not yet found its way, the magpie represents the “hoodlum element” in bird society. But when the English — Sparrow invades its domain, the magpie will become, by compari- ` on, a most estimable member of the avian fauna of that region. Almost any cañon which has a considerable sheep corral and _ Supplied with a few scattered clumps of live oaks, cottonwoods _ _ ® sycamores, is quite sure to have its colony of magpies.s And = _ When you enter one of these cañons you are apt to know oftheir Presence long before you come within gunshot of them, unless ““Y, as is sometimes their custom, remain quiet and hidden until _ You are near them, when they open fire upon you with volleys of — nn, imprecations and maledictions, which nothing but a charge _ __ of shot will stop, : : a is ETA = Duly, 608 The Yellow-billed Magpie. Such a place as this is Wheeler cañon, a few miles down the Santa Clara valley from Santa Paula. By former visits to this cañon I had kept myself informed as to the progress these birds were making in their nesting. So on April 2, 1881, Mr. Fred. Corey and I paid the cañon a visit, believing that many “ full sets” would be gotten. We started from home early in the morning and drove down to the cañon, fully prepared to spend the day. As we drove leisurely along the foot of the mountain _ slope, numerous brown birds (Pupilo fuscus crissalis) and valley quails (Callipepla californica) scurried from our path and hid themselves in the sage-bush chaparral which there abounds; and an occasional burrowing owl (Speotyto cunicularia hypogea) would salute us with a school-boy bow as we passed. Where the cañon opens into the valley are many large spreading live oaks which, with their dark-green foliage and spreading form, resemble large apple-trees. Many of them have beautifully rounded tops, whose bases are only a few feet from the ground, - and whose small dark-green leaves are so thickly set that it is impossible to see among the branches except from below. Far- ther up the cañon are a number of cottonwoods and a few wil- lows, and still farther more oaks and several sycamores. He who has collected only here in the East hardly knows how rich may be the results of a day spent in such a cafion as this. -~ Here every tree could be climbed with no great difficulty, and anything it might contain was nearly always obtainable. When we reached the sycamores and cottonwoods the hooded and Bal: 8 lock’s ‘orioles, happiest of all the cafion’s happy birds, flitted among the green leaves, delighting the eye with their royal dress, _ and the ear with their rich melody of song. And a pair of mag- pies flew up, from the edge of a little stream where they ʻa% come to make their morning toilet, and perched upon a cere = wood near by. Emphasis was given to their scoldings by excite `, Jerkings of the tail and body after the manner of the jay- Be as we had decided to begin collecting at the upper end om _cofion, we passed on without disturbing the riest which we plainly _ Saw in the tree’s top. As we neared the upper end of the gt _ a California vulture (Psendogryphus californianus) rose from ” _ ground in front of us, where lay a dead pig upon which feasting, and soared away to the higher mountains. I gree no bird of more majestic flight than this great vulture of out i ` Western coast. While rising from the ground his movements are anything but graceful; he starts with a few very awkward steps and still more awkward flaps of his immense wings, but after reaching an elevation of fifty to seventy-five feet, flapping of the wings ceases, and as he circles above you, ascending higher and higher on motionless wings, he proves himself king of the soar- ing birds. But the magpie was the object of our trip, and to her’ we must return. Our time was well selected, for the nesting was atits height. The large globular nests were seen in the tops of anumber of trees, and most of those that we climbed to con- tained good sets of eggs. We obtained nine sets altogether. : Five nests were found in sycamores and contained three, six, seven, Seven and nine eggs respectively. The full nest complement for each of the first two sets had evidently not been reached, as the eggs Were perfectly fresh. Incubation had scarcely begun in the two sets of seven each; and the nine eggs of the other set showed but slight embryonic changes. Two sets of eight eggs each were taken from nests in live oaks, and with these incubation had proceeded several days. One beautiful set of eight eggs was found ina nest in the top of a willow near the lower end of the cafion. In only two or three of the eggs were embryonic changes visible. But one nest was. ound in a cottonwood, the one we had “ spotted” in the morn- ng, and but a short distance from the willow just mentioned. In this nest we found four fresh eggs. Thus from the nine nests we Sot sixty eggs, which we regarded as a pretty fair day’s collect- mg. From the above facts it seems safe to conclude that the Usual nest com to nine eggs, and that the sycamore is the favorite tree in which to nest in that region, ‘Part.

Quite a number of old deserted nests were found, partic- ularly inf the live oaks near this mouth of the cafion, where we found no recent nests at all. But a few years before a school- house had been built near this grove of oaks, and the “ small boy” proved too much for even the magpies, who retreated up the cañon, leaving their tents behind them. | The eggs of the yellow-bill magpie vary considerably in color as well as in size and general shape. The description of the color given in Baird, Brewer and Ridgway, and copied by Mr. Oliver Davie in his “ Egg Check-list of North American Birds,” is applicable to nearly all the specimens I have seen, viz, “ The - ground-color is a light drab, so clearly marked with fine cloud- ings of an obscure lavender color as nearly to conceal the ground, and to give the egg the appearance of an almost violet-brown.’ One set of four in my collection has the lavender very pro- nounced, and in quite large spots or blotches, rather most numer- ous about the larger end. The eggs of this set measure 1.35 X 95, 1-43 x .90, 1.29 x .90 and 1.33 x .94—the average 1.35 * 89, being the largest of any of the sets I have seen. Another set of = eight gives 1.18 X .85 as the smallest, 1.40 X .85 as the largest and 1.30 X .8 as the average. The average of a set of six give? by Mr. Davie is 1.30 X .89, and on another page he gives 1.20 X .92, presumably the average of many sets, B.B. & R. give i x .9O as the measurement of an egg from Monterey, Cal. Fhese last measurements seem rather under the average of those I have seen. Several of the nests to which we climbed were old deserted _ Ones, and contained no eggs.

The prominent ures which separate them, osteologically speaking, from other Artiodactyla are three, viz., the absence of a canal of the cervical vertebrae which in other Mammalia encloses the vertebral artery (Fig. 1); the presence of an incisor tooth on each side of the feat > Fic.

The peculiar cervical verte- o nstitute a specialization, but whether degenerative or pro- 612 The Phylogeny of the Camelide. [July, gressive remains to be ascertained. In one respect this line ex- hibits a high specialization, which is present at the earliest known period of its history. This consists in the reduction of the lat- eral (11 and v) metapodial bones, so that but two functional toes remain (see Fig. 1, c-/). This condition has been reached by the more typical artiodactyles after a much longer lapse of time, for most of the extinct and recent types display lateral digits ina well-developed or rudimentary condition; in but few of them have they totally disappeared. In another respect the line of the = — Camels attains a higher specialization than that of the typical ruminants, although its beginning is that which is common to the entire suborder. This is in the dentition. The reduction in numbers of teeth showed by Owen to characterize the historical succession of all Mammalia, is carried further in the molar series of camels than in any hoofed order; for in the final term or | genus, Eschatius (Cope), there is but one premolar left in the | upper jaw, and that is reduced to a simple cone. The true molars never reach the complexity of those of the other line, of ` the Bovidz or oxen, nor do they become prismatic as in that family, but retain the short crown well distinguished from long roots, which belongs to all the earlier Mammalia. ae The successional reduction in the numbers of premolar torth ko in the family of the Camelide is shown in the following table. __.

In this genus we reach the stage, in tracing back the ancestry of the camels, which We find represented by Oreodon in the series of the Chevrotains (Tragulidz), or the Gelocus in the line of the cattle and deer. It is probable, though not certain, that in Protolabis the metapodial bones are combined into a cannon bone as in the Camelide. If so it differs mate. nally from its predecessor, the genus Poëbrotherium, and must be regarded as the type of a special family, the Proto- labididze, : The Poébrotheriidze have their general characters like those of the Protolabi- didæ, but th R IG, 2. — Carpus ®, but the metapodial bones are en- bone first from New teeth are truly selenodont, and the cres- vidual Fig. 12; a, pag b, c i d, i erior views. riginal, ents, as in the other families, are but 8 Rept.

Such forms are already nown as ancestral to some other. Ruminantia, as for instance the genus Anthracotherium, where the external cones are flattened on the outer side, or Dichobune; where the cones are not flattened’at all. In both of these genera : there are five tubercles to the superior molars, and the lateral (11, v) digits are present. We possess some fragments, however, of a lost genus from the age of the Poëbrotherium (the White River Miocene, or Oligocene), which very probably represents the one which fills the interval. This has been named Stib- arus (Cope), and it is only known from parts of lower jaws which contain premolar teeth. These have a great resemblance to thẹ corre- i Gia sponding parts of an older genus of the same tise capes and end of line, -Pantolestes, from the Wasatch forma- wn eitoni Let tion or Lower Eocene. It might be suspected _ Original. that, Stibarus is a member of the Panto- lestidze but for one fact., The superior molars of Pantolestes be- long to the primitive type which has only three tubercles or cusps. No genus of ungulate mammals having this character is known to pass the bounds of the Eocene series of epochs in any country, and it is extremely improbable that Stibarus will prove to be an exception to this rule. I have very little doubt that the superior molars will be found to be quadritubercular, but it is : impossible to be certain whether the tubercles are simple oF cres- _centic. The resemblance of the premolars to those of Pantoles- tes leaves the probabilities in favor of their being simple. In _ case Stibarus represents a family in the wide interval between “Ta oe Pantolestide and the Poébrotheriide. Messrs.

This I have believed would be found to have been from some yet undiscovered type or sub- order of the order Amblypoda! None of the known families of that order can have occupied this position, for although their general organization is appropriate, their superior and inferior molar teeth have been modified too much from the simple tritu- bercular type on which they are built. The ancestor of Panto- lestes was an amblypod with the tubercles of its tritubercular Superior molars entirely simple or conical. No such form has yet been discovered, but I have, in anticipation of such discovery, named the suborder the Hyodonta. = f Co igi Th iform is imperfe > l zoryphodđon (original), e cuneïform is imp , Ore it i £, lunar; Cu, cuneiform; 7z, trapezium; 7v, trapezoides; My, magnum ; | » Sncitorm, Fig. 4.

[July, inwards of the second row on the first, in both the fore and hind feet. This rotation has resulted sooner or later in the loss of the internal digit (thumb and great toe) from both extremities. In the history of this sliding inwards of the second row, the out- side element of the row has always preceded in time the inside element. The Amblypoda (Fig. 5) show this clearly. The unci- form bone has extended inwards so as to support the second bone of the first row (lunar) in part as well as the one which properly rests on it (cuneiform). But the magnum has not slipped inwards so 3 as to support the scaphoid of the first row. That continues to be supported by its proper successors below, the trape- zoides and the trapezium, the latter taking half the burthen. This structure (Fig. 5) is ab- solutely intermediate between that of the Taxeopoda (Fig. 4), and that of the Diplarthra (Fig. 6), and I imagine that all ungulates in passing from the taxeopodous to the diplar- throus stages traversed the conceivable path would have been through a type in whi ee ee at se rng, below. te or Wyo a pienis ha of Wind river, the unciform did not pe ae bg ad ind ag Report U.

The only other of the cervical vertebre (Fig. 1). 1886.] The Phylogeny of Camelide. 617 The following suggestions as to the origin of the three pecu- liarities of the cameloid series, or Tylopoda as they have been called, may be made. The imperfection of the distal metapodial keels (Figs. 2, 3 and 7) is probably due to the £} early development of an elastic pad of connec- į i tive tissue beneath the proximal phalanges. It is this pad which gives the foot of the camel its peculiar lateral expansion, and causes its step to be both elastic and silent. This structure has relieved the metapodials of the concussions to which the feet of other Ruminantia are subject, and I have advanced this fact as the cause of the peculiarity of the metapodials above mentioned.? The cause of the absence of superior incisor teeth is unknown, but has been supposed to be complementary to the presence of horns in the Ruminantia. None of the camel line have horns, and the presence of the single incisor on each side may be connected with this fact; but why two of the incisors on each side should have been lost under the circumstances, is not ex- Plained. Nor has any explanation been offered for the absence of the vertebrarterial foramina : There have been six species of the Pantoles- y tidæ described, all belonging to the genus Panto- y y a The only ones of the six which are Paq. — Misi n from parts of the skeleton, are the P. foot of Počbrotheri- “gicaudus Cope, of the Bridger Eocene epoch, = — from and the P, brachystomus of the Wasatch Eocene ed in Fig. 1.

The tarsus of the P. érachystomus is known, and it is truly ruminant, though all the bones are distinct (Fig. 8). At the upper end the adjacent sides of the metatarsal bones are flattened and applied together, so that the later formation of a cannon bone by their fusion, must have been of easy accomplishment. The dis- : tal parts of these bones as seen in the P. longicaudus are not closely appressed, but are quite distinct from each other. The P. “AMERICAN NATURALIST. 618 The Phylogeny of the Camelide.

Both lines died out in North America, and of the two, the camels only have certainly held their own in South America. The history of the succession of horses in Europe, although not as complete as that in America, extends over as wide a period of time. Not so with the camels. There is no evidence of the existence of the camel line in the old world prior to the late Miocene epoch ; and so far as the existing evidence goes, the new world furnished the camel to the old. Camelide only appear in South American palzontology in the genus Auchenia, in Pliocene time, in the Pampean beds, The best known species are Auchenia weddellii and A. intermedia of Gervais.

EDITORS: A. S. PACKARD AND E, D. COPE. Various suggestions have been made as to the permanent organization of science at the National Capital. The necessity for the employment of experts having been felt in various depart- ments of the Government, commissions and offices for the con- duct of research have grown up in them. The results have been greatly to the advantage of the Government and of the people, and have often represented important advances of science itself. The efficiency of these commissions has, however, often been impaired through their association with the various bureaus and departments under which they are placed. This comes from their necessary direction by non-experts and the quantity of routine work which may be required of them. There is also necessarily _ More or less overlapping of the similar offices in the different departments. Many of the commissions have been from time to _ time threatened with total extinction through the want of knowl- _ edge of their utility by some of our legislators. Several illustra- tions of this fact have recently occurred in Washington. s4 superintendent of the Coast Survey has been removed, place taken by superior clerk of the Treasury Depart™ t. 4 1886.] Editors’ Table. 625 A bill has been introduced into the House of Representatives by Mr. Herbert, of Alabama, which forbids the publication of its results by the Geological Survey, which, with other restrictions, is almost equivalent to its abolition. On the other hand a bill has been introduced by Mr. Reagan, of Texas, creating a “ Department of Industries,” to be repre- sented in the Cabinet. This bill contemplates combining in the new department the following divisions: Agriculture, Labor and Commerce, The division Agriculture embraces the subdivisions: 1. Agricultural products, including botany, entomology and chemistry; 2. Animal industry; 3. Lands, including the geo- logical survey. As regards the intrinsic merits of this proposed new depart- ment we have nothing to say, but we think there are better ways of disposing of the scientific work of the Government. The above plan omits necessarily a number of important scientific bureaus, and does not provide for the consolidation of all the offices which pursue a given branch of science. Thus there will be a chemical commission in the Agricultural Department and another in connection with the Navy, as at present, and so on. If it can be done properly, the creation of an organization to be called the Department or Bureau of Science and Public In- struction, to be embraced in the present Department of the Inte- nor, might meet the necessities of the case. Such a department would embrace the present Naval Observatory, Nautical Almanac, Signal Service, Coast Survey, Fish Commission, Geological Sur- vey, Agricultural Department, Bureau of Statistics and Bureau of Education. The diverse and heterogeneous character of the Ove divisions might be remedied by a suitable re classification. Each of the divisions should be under a capable expert, who should devote his time to promoting the efficiency of the work. nancial matters to be under direct management and control of the head of the entire bureau. But the essential to success of this or of any other plan for pro- Moting science at Washington is that its offices be removed from the field of political patronage. How this is to be done ‘is the uestion. The Smithsonian Institution as a private corporation, and the National Museum as under its direction, are happily re- Moved from such contingency, and any system which would the scientific commissions and bureaus in a position of bal security, would be a great benefit to them, Nothing would ~ §ained in this direction by the creation of the proposed new : department, For this reason the commission appointed by Con- - Ses to investigate the relations of the scientific bureaus to each other and to the Government has decided that no change of "ganization should be made at present. a 626 ‘ Recent Literature.

Asiatic News.—The Russian Trans-Caspian railway was by the end of last year opened as far as Ghiaurs. From this spot to Merv the necessary earthworks were completed. From thence to Chardjui, 118 miles from Merv, the route will be across desert. It is proposed to prevent the access of moving sand by plantations along the line. An ethnographical map of Asia, six and al feet by four and a half feet, showing the localities of 136 divisions of peoples and languages, in twenty-six tints of color and shading, has been made by Herr Vincent von Haardt, of Vienna.— recent issue of China Review contains an article, by Mr. C.

The river Yarmut whose course marks the southern limit of the Jaulan basaltic region, receives from the north several tributaries, which are here for the first time correctly mapped. The Rukhad, one of these, rises at the foot of Mt. Hermon (Jebel-esh-Sheikh). Its tribe the Wady Seisun, falls 517 feet in 420 yards by a succession © cataracts. These rivers have their sources in springs, and there are clear indications of the existence of large reservoirs of under- ground water in the basaltic and calcareous formations. Asiatic ĪSLANDS AND AUSTRALIA, ETC.—Barren and Narcoudam, two volcanic islands belonging to the Andaman archipelago, ai lying east of the main islands, have been surveyed by Capt.

Most of the tribes of the river border have no garment whatever, but in some tribes the men wear a “calembe” of bark, and in the villages lower down the river the men don pantaloons and the women a chemise when they are full-dressed. Some tribes still inter their dead in the “maloca,” or hut, which the Tucanas immediately abandon in order to build another. M. Thouar reports as the result of his last journey to the rapids of the Pilcomayo, that it is possible at any season of the year to go from the mouth of that river at Lamboné to the mission of San Francisco de Solano, in Bolivia, at the very foot of the Andes. The difficulties caused by ac- cumulations of trees and the consequent formation of shallows can, he believes, be overcome.

GEOLOGY AND PALAIONTOLOGY. _ THE Fossi Man oF Penon, Mexico.—On my return to this city after a long absence, I read the observations published in the New York Tribune concerning my account of the fossil man of the Peñon. It will give me great pleasure to clear up the doubt expressed by Professor Newberry with regard to the importance of the discov- ery of the man of the Peñon _Professor Newberry does not believe in the importance of the ‘scovery, and argues in this manner: “The calcareous bed in | Which the fossil remains were found must have been modern tra- vertin; it could not have been deposited below the -waters of a l _ lake, but probably belongs to an aérial or superficial formation, since otherwise it would be of equal thickness and uniform on the bottom and on the borders of the lake; if the limestone is siliceous, it must belong to a hydrothermal deposit.” It is above all certain that the limestone is not modern tra- vertin, for it does not form concentric layers above the human : remains, nor over other recent objects, as would be the case were : it such, e bones are sealed up, so to speak, in the calcareous : rock, without being in any way coated, and were probably depos- ited while the rock was yet soft and under water. As the clear- : ances and excavations at the foot of the small mountain of Pefion have been continued, I have been able to prove the persistence of ; l the facts indicated in my article published in the NATURALIST, z = Published in 1884 by Professor Antonio del Castillo and by mẹ. ~ œ S new excavations have shown more clearly yet the thre — formations of which I have spoken, ranged as follows: At) A Superficial layer 10 centimeters thick, formed of vege- table earth, containing lacustrine shells and fragments of modern A = A layer of calcareo-siliceous tufa, of but slight hardness, Min Nains of old pottery, 50 centimeters thick. o - : (3) Siliceous limestone, very hard, in a thick bed, inclined © -wards the north, Here are found roots transformed into men- — eo 634 General Notes. - _ tor in many fissures of the Peñon rock thin veins are found compe _ Ofcalcareous matter in some cases, of siliceous in others, Bes! w#ite and lacustrine shells, It is in this bed that human remains, and no others, have been found. The thickness of this bed is not yet known, as it has only been opened toa depth of 1.2™ The bed is covered by a thin layer of a limestone richer in quartz, a true ribbon, dividing the adjacent formations. Not a single modern object has been found in this bed, nor in another similar one situated to the south of the mountain, more than a meter thick, and resting on a lacustrine and turfy formation. Two miles northwest of Peñon there is another bed of sili- ceous limestone at the foot of the mountain chain of Guadalupe, and stretching over a great length, This limestone is in compo- sition, appearance and position, identical with that of Peñon, con- taining roots transformed into menillite, and in its upper part fragments of old pottery. What is most important in this for- mation zs the existence of elephant bones sealed in the hardest bed, Like that of Peñon. These bones have been taken out on many occasions, I have done it myself in the presence of the pro- fessors of the National Museum. ; The distance from this bed to that of Peñon is so inconsider- ~ ra . é . ee E SO as to occupy a position different from its primitive one, ale Peñon having for an enormous number of years been surroun man The hy- ct in the Geology and Paleontology. 635 upon the summit of the Guadalupe mountains occur masses of shell-rock (masses lavignes) impregnated with siliceous lime- stone, which demonstrates their contemporary origin. What hin- ders me from believing that the existing hydrothermal springs at the foot of the Pefion can be the origin of the formation which surrounds the mountain is that these springs form only isolated and insignificant deposits, which cannot spread out uniformly like those of which Professor Newherry speaks, and which are characteristic of geysers. The above-mentioned springs were probably the last traces of the abundant eruptions of calcareo- siliceous waters which formerly shot forth at the same time with veins, or of the alteration of the basalts of the mountain. We must, therefore, believe in the importance of the discovery of the man of the Peñon. No-one can be more anxious than I to base these discoveries | Upon clear and well-determined facts, as I stated in my arti- cle in the Naturauist. Professor Castillo and myself have assiduously studied the Pefion formations, and with the sincerity which scientific truth exacts we will inform the learned World of later discoveries. If it should happen that in the rocky . omb of the man of the Peñon the remains of his primitive Weapons or the iron of his conqueror should be found, we shall doubtless be the first to announce it—Mariano Barcena. < JON THE Fossir FLORA OF THE LARAMIE SERIES OF WESTERN Canana. — The Laramie series, formerly known as the Lignite Ter- tiary or Lignitic group, occurs-in Canada, principally in two large areas west of the tooth meridian and east of the Rocky moun- © tains, and stretching northward from the United States boundary. . c “se areas are separated from each other by a low anticlinal of | retaceous beds, over which the Laramie may have extended Previously to the later denudation of the region. Ri areas may be designated—(1) The Eastern or Souris al ver and Wood Mountain area ; (2) the Western area, extending “ong the eastern side of the Rocky mountains and across the pper „Waters of the Bow, Red Deer, Battle and North Saskatche- wan rivers, In the southern part of the district of Alberta it has been been _ Possible to divide the Laramie into three parts, which have T pen respectively, in the Reports of the Geological Survey midd] da, (1) the lower or St. Mary River division, (2) the ~ © or Willow Creek division, and (3) the upper or Porcupine , Sa pa n oe the Royal Society of Canada, May, 1886, by 636 General Notes. : [J uly, Hill division. Of these the lower and upper contain fossil plants, more especially the latter, and corresponding horizons can recognized by these in both of the great areas above referred to. The flora of the lower division has a close alliance with that of the Belly River group of the underlying Cretaceous, while that of the upper division is in the main identical with that of the Fort Union group of the. United States geologists, as described by ¢ Newberry and Lesquereux. In the Eastern area the lower beds of the Laramie rest on the Fox Hill group of the Cretaceous, and are in turn unconformably overlaid in the Cypress hills by beds referred, by Professor Cope on the evidence of mammalian remains, to the White River , division of the Miocene Tertiary. Thus the geological horizon of the Laramie is fixed by its stratigraphical relations as between the Upper Cretaceous and Lower Miocene formations. The evi- dence of fossil remains accords with this position. The Lower È Laramie has afforded reptilian remains of Mesozoic aspect, asso- ciated with fishes and mollusks, some of which are of Eocene : types, according to Cope and Whiteaves, and its flora is akin to that of the Upper Cretaceous. The Upper Laramie has afforded a flora so modern in aspect that it has even been regarded as Miocene, though in reality not later in age than the Eocene. The Willow Creek or Middie Laramie division may therefore (as sug- oY gested by the author in his memoir of last year on the Western Cretaceous) be regarded as the transition from the Cretaceous tO the Eocene. : Miocene period, and these difficulties cannot as yet be shi overcome, though they are gradually being removed. In Canada, since the plants began to be collected and studied, there has hs _ little doubt on the subject, and the author now, as herana =, holds tothe correlation with the Laramie flora of the so-ca i Miocene of Mackenzie river, Alaska, Greenland and Spitzberge > and believes that they should be regarded as not newer Eocene. : oE The greater part of the paper is occupied with the dnt _ Of the fossil plants of the formation, including those collecte h e Eastern area by Dr. Selwyn and Dr. G.

NOTES ON THE VARIATION OF CERTAIN TERTIARY Fossits IN OVERLYING Beps.—In the Southwestern Old-tertiary there are some high vertical exposures, which show different fossiliferous beds vertically above each other. One of them is the file 1885, p. 71. The “ Higher Vicksburgian,” consisting mainly of reddish sands, contains those fossils usually known as Vicks- burgian fossils ; the bed, “ Lower Vicksburgian,” a dark grayish marl, contains a very similar but not entirely identical and less humerous fauna; both are separated by about thirty feet of lime- stone. Some of the lower species are not known from the higher bed, which, however, is at least partly owing to different methods of collecting in both beds. The main number of species of the lower bed occurs also in the higher one. In most of them, for Instance, Buccinum mississippiense Conr., Sigaretus mississippiensis Conr., Pleurotoma congesta Conr., Murex mississippiensis Conr., Terebra divisura Conr., Trochita trochiformis Lea, Turritella cæla- aD ferences ; Cytherea sobrina Conr. from the lower bed is in gen- eral longer than from the higher bed. Ten specimens of the higher bed, taken without special selection, showed, if the height to 1.33, an average of 1.30. More striking is the relation of the two : forms of Ficus mississippiensis Conr., which species in the lower o age and size in both varieties, the higher variety shows one more System of revolving lines. This difference between the two varie- hes is not very striking, but is large and constant enough to dis- tinguish the forms of the two beds without reference to the litho- logical contents of the shells.

In these consecutive beds we frequently find the same species, sometimes without apparent change, sometimes represented by slight variations and in some cases by strongly modified varia- tions, This material from Alabama, which I refer to, is in the collection of Mr. T. H. Aldrich—Ovso Meyer. f Among the samples of rocks during the soundings of the Talisman, mostly from depths of 4000 to 5000 meters, the older metamorphic rocks are more gên- erally represented than the eruptive series. There were seventy- three specimens of limestones, sixteen of arkoses and nineteen of sandstones, the latter sometimes rich in remains of biotite and From the collections of Lieut.

The great value of this work lies in the fact that the descriptions are very full, and include accurate measurements. n the year 1882 P. A. Saccardo began the publication in «Padua, Italy, of what is destined to be one of the great books of the century, the Sylloge Fungorum, designed to contain all the known fungi of the world. The first and second volumes are devoted to the Pyrenomycetes, of which great group about 6000 species are described. The third volume, devoted to the Sphe- ropsidez and Melanconiez, appeared in 1884. It contains de- scriptions of over 4000 species. Volume Iv appeared in April of the présent year. It is devoted to the Hyphomycetes, and de: scribes over 3500 species. TR The descriptions in Winter’s work are in German, those im Saccardo’s Sylloge, in Latin. Both are full, although the treat- is much more satisfactory in the former. Saccardo merely compiles, and thus often admits the same plant under more than one name, while Winter is exceedingly critical.

This improved copy is now exactly seven and three-eighths inches long and four and seven-eighths wide, and weighs but thirteen ounces. It slips into an ordinary pocket with the greatest ease, and can be carried by the collector wher- ever he goes. ow it must be remembered that this reduced copy of the “ Tourists’ edition” is printed from the identical plates used for the large book, and that apparently no attempt was made by the printer to reduce the size of page by printing closer to the zumer margin, where at least a quarter of an inch might easily have been saved. It is probable that with considerable care the width of the book might be reduced to four and a half inches. _ Until we can have something better let us have thin-paper edi- tions of Gray’s, Coulter’s and Chapman’s manuals, printed and bound with narrow margins a// around, and „with flexible covers which project but little if at all beyond the pages.

Romanes read a paper “ On physiologica selection: an additional suggestion on the origin of species,” The author contended that the theory of natural selection has been misnamed a theory of the origin of species. It is, in truth, atheory of the origin of adaptive structures, and, if unassisted by any other principle, could not effect the evolution of species. The only other principle that could here assist natural selection would be one that might mitigate the swamping effects of intercrossing. This may be done by geographical barriers shutting off a portion of a species from the rest, and allowing that portion to develop an independent course of varietal history without intercrossing with the parent form. It may also be done by portions of species migrating, changing habital stations, &c. But it mgy also be done by what the author calls physiological selection, or in virtue of a variation taking place in the reproductive system in the di- rection of sterility (whether absolute or partial) with the parent orm, without impairment of fertility within the varietal form. For instance, the season of flowering or of pairing may be either vanced or retarded in a portion of a species, when all the indi- | viduals in that portion (or new variety) would be absolutely sterile’ towards the rest of the species, while completely fertile among themselves, They would thus start on an independent course of variated history —Enghsh Mechanic. Mecuanics or Soarinc.—Professor Hendricks in the NATURA- List for June, imports into the “ mechanics of soaring” a momen- tary force which I do not think improves it. There is no “ mo- mentary” force concerned with any part of the activity that I am aware of. The birds are in the air quite early in the morning, and continue there until nightfall, all the forces concerned in their movements being active every instant of the time. ne air pressures beneath the surface produced by the normal notion are constant, and the expansion of these pressures against - the rear curve is constant, and this expansion gives the lateral ese motion. They are both derived from the gravitating force of the ae mass of the bird. There is no other force operative upon the bird in the act of soaring. ioe f ne 654 General Notes. [July, which is to deny the equality of the forces producing the balance. Bear in mind that I have carefully excluded inertia, or in other words, mass acceleration, from the problem. The birds have the power of flapping, or falling from higher to lower levels, to initiate their movements. Soaring has nothing to do with acceleration. It deals with motions of uniformity only. Hence I am justified in holding that one or two pounds of constant pressure is compe- tent to drive the plane edgeways 1000 feet per second against air friction only. As frictional air resistance approaches zero, a small force would move the plane against it with great velocity. No weight is lifted in the upward motion, as the forces producing the weight are already employed to their total value, as fully shown. s the force producing the lateral motion is derived from the gravity of the mass, I am also justified in holding that a soaring bird is trafislated at right angles to the gravitating force, or hori- zontally, solely by the action of that force. It will be noticed that forces were on hand in quantity sufficient to produce the movement.—/. Lancaster, Chicago, Til., June 5th, 1886. LimuLus IN THE PaciFic.—My friend, Mr. H. W. Turner, of the U.

To this observing seaman we owe our first accounts of the home of the great auk or “ penguin” on the Island of Birds, now Funk or Fogo island, on the northeastern coast of New- foundland ; also of the Bird rocks of the Gulf of St. Lawrence. ' While harboring at what is now Funk island Cartier, after describing the great auks, tells us that he sawa white bear. In his own language, done into quaint English by Hakluyt: “And albeit the sayd Island be 14 leagues from the maineland, not- withstanding beares come swimming thither to eat of the sayd birds: and our men found'one there as great as any cow, and as white as any swan, who in their presence leapt into the sea, and upon Whitsun-monday (following our voyage towards the land) : we met her by the way, swimming toward land as swiftly as we could saile. So soone as we saw her, we pursued her with our boats, and by maine strength tooke her, whose flesh was as goode F to be eaten as the flesh of a calfe two yeres olde.” From this graphic and circumstantial account we feel sure that this was the great white or polar bear (Ursus maritimus); that it reached its full size, was not uncommon on the mainland (John Cabot says the land was “full” of them), and that it bred there, as those mentioned by Parmenius in 1583 were probably young ones. The white bear is still occasionally seen on this coast, as Rev. Mr. Harvey ‘states :! “The seal hunters occasionally encounter the white or polar bear on the ice off the coast, and sometimes it has been known to land.” Now, if in these early times of Cabot and Cartier the eastern - PU a Se a ee of Maine Our supposition is based on the following facts: In an ancient map of “ New France,” by the Italian Jacomo di Gastaldi, in about the year 1550, republished by Kohl, and which we here present of reduced size, what we should consider as veritable white bears are depicted as swimming in the ocean far from the coast of what must have been Nova Scotia, and near to but west of Sable island o Oe PTE ee a a ee Oe ee ee NR ey Se O j ° —, A a) -i © co 5 ey rt) =] on = feb] n rt Er o D. 7 ai or is) 5 Qu ao i 3 vq p 6 m ° Sonal o E auae animals represented are bears admits of little doubt; M he four, Geuses the lowermost one iia seal; it is drawn with- — like Cars, while the three other figures have large, drooping ears, — é Í -t Halton and Harvey’s Newfoundland, Boston, 1883, p. 193. ‘F r “Isola della rena.” In the map the bears are placed to -~ ” those of a bear, At any rate, if the locality was put in at oe ra 658 General Noirs. [July, haphazard by the map-drawer, why should white bears be also represented, as they seem to be in the ocean off Isola de Demoni. The figures of the black bear, as well as of the rabbit and of the aborigines are well drawn, and it seems not unreasonable to infer that white bears were actually seen and reported to the south and west of Newfoundland. That the white bear may have visited the coast of Maine, near Portland, is further proved by the probable discovery by Mr. E. S. Morse of a white bear’s tooth in the shell heaps of Casco bay. Speaking of the bones of the bear found in a shell heap on Goose island, Casco bay, Maine, the late Professor Wyman remarked in the AMERICAN NATURALIST, I, 575, January, 1868: | “The bones of the dear, though much less numerous, were = Phe a ee ee a 1886, } Zoölogy. 659 the last-mentioned species, as it does also in the shape of the crown—but it must be unsafe from a single specimen of the molar in question to attempt to identify them. The former exist- ence of the polar bear on the coast of Maine is rendered quite probable by the fact that the tusk of a walrus has actually been found at Gardiner.” That the white bear formerly was an inhabitant of Newfound- land seems probable from the facts we have brought together, and it is to be hoped that the antiquarians and naturalists of New- foundland will investigate the shell heaps, should such be found, of that island for further facts bearing on this subject. We will now turn our attention to the former presence of the white bear on the Labrador coast, where the settlers still call it the “water bear.” We find only in Cartwright’s Journal refer- ence to this creature, but this is sufficient to show that it bred on and permanently inhabited this coast from Belle isle or Chateau _ bay northward. A white bear was killed in 1 769 at Pitt’s harbor, Chateau bay. There is a “ White Bear Sound ” on Cartwright’s wich bay. In 1770 Cartwright saw the track of two large white island, and in the following May another was observed. White bears were also seen up the rivers leading into Sandwich bay, and On pp. 410-11 Cartwright describes the habits of the white bear in Labrador, stating that the young are born in March, the parent ng forth usually one at a time, sometimes two.

The most important part, it seems to me, is not the connection of cell to cell, but of layer to layer by means of processes of the cells. About the middle of the fourth day several of the hypoblast cells approach the epiblast in the middle line of what will even- 7 tually be the ventral surface of the embryo. This is the begin- = ningofa mesoblastic keel such as Balfour described for Agalena. The epiblast cells in the ventral middle line, after altering their shape, increase by division and take a considerable share in the formation of the keel. The hypoblast cells below them also increase, and on the fifth day the mesoblastic keel is complete, in the formation of which both epiblast and hypoblast have taken F part. The keel is still present on the sixth day, but the cells composing it are becoming elongated in a plane parallel to its | surface. They then spread out to form two definite splanchnic and somatic layers of the mesoblast below the epiblast. These two layers are connected. The keel disappears on the seventh and. eighth days, and on the ventral surface the epiblast cells assume a columnar form, thus giving rise to the ventral plate. _ _ The mesoblast now becomes thicker on each side of the median line, both layers being concerned in this thickening, where they become indistinguishable. Outside the thickenings, that is, farther away from the middle line, the two layers are closely ie that of the future segments of the body. There are at first “gat somites, corresponding with the eight segments of the embryo when hatched. These somites are at first solid ; after- wards a cavity appears in them.

[July, same time the hypoblast cells begin to form the mesenteron, men, On the tenth day the ventral flexure is formed by a deepening of the transverse furrow between the seventh and eighth segments. _ As this furrow deepens and the embryo increases in size, the last segment grows in length. At the same time the embryo curves round toward the ventral surface, the end segment being bent round against the head. The eighth segment is longer than the others except the head. Even as late as the twelfth day, when the nervous system is far developed in other parts of the body, in the eighth segment the tissues are imperfectly differentiated, the ` nerve cords not showing any ganglia, but lying on the epiblast and not quite separated from it. Ata later period of development the anal segment is constricted off from the eighth, while from the anterior part of the latter, the additional segments formed in the course of development are derived. These additional seg- ments are therefore intercalated between the seventh and ninth. » Just before the appearance of the ventral flexure the embryo develops a cuticular envelope over the whole surface of the body. This is the so-called amnion of Newport. Just before the forma- tion of the ventral flexure the nervous system is formed. first traces of this consist in a thickening of the epiblast on each side of the middle line; this is soon followed by the formation of a shallow furrow between the thickened parts; this longitudinal furrow corresponds with that described by Metschnikoff in Strongylosoma. a present for each segment except the last. The posterior por- tion of the nerve cords is completed at a considerably ene = stage of development. The nerve cords are widely separated, bit a are connected by a thin median portion. In later embryonic lite ae are closely approached to one another, and almost form one cord. On the eleventh day the embryo has increased considerably a size. The ventral flexure is complete, and the animal lies wit the long end segment folded closely against the rest of the z $ the end ofthe tail being against the stomodæum.

The process is somewhat geneous investment of yolk which lies within the u has, on ~ 666 General Notes. (July, the same way in fishes as in Myriopods, viz., as a direct canalicu- lar vacuolization of the yolk passing through its central longitu- dinal diameter, the periblast would doubtless then represent the hypoblast or what it did in very primitive fish-like forms, while externally it would have been covered by a true splanchnopleure which had been developed in advance of the permanent hypoblast of the mesenteron, though the latter had been primarily derived from the primitive hypoblast. he eggs of the Myriapoda, it is to be remembered, represent a very peculiar type, that is, they at first have the germinal matter concentrated in the center, but as development proceeds the germinal matter, after segmentation into a number of cells, is repelled centrifugally or to the outer surface of the ovum. The primary segmentation therefore occurs in the center of the egg and not at one side or superficially until some progress in seg- mentation has been made at the center of the egg. This prob- ably characteristic mode of development seems to distinguish, in a measure, the Myriapoda from other Arthropoda, since in no other arthropodous form does the vitellus so constantly occupy a superficial position and so completely invest the first segmenta- tion cells, which are then aggregated in a cluster at the center of D place of publication of which is here cited, William A. Locy has . very carefully worked out the development of the spider (Age- lena), and obtained a number of new and important morpho results.

Sections show that the cavities of the limbs are prolongations of the cavities of the corresponding meso- dermic somites. The nervous system at first consists of two rows of ganglia, one to each somite; these are widely separated in the middle line, except in the head and tail lobes, where those of Opposite sides are fused. The stomodzum arises as an invagi- nation between the ganglionic thickenings of the cheliceral oe and immediately below the ventral margin of the cephalic. ate About the time that the ventral flexure appears, or when the . embryo becomes folded upon itself, the proctodzum, heart, lungs, trachea, spinning glands and muscles develop. The chelicere and pedipalpi appear as postoral structures, but in the course of further development they appear as preoral appendages. At an early stage the proctodzum is enlarged by the outgrowth of its dorsal wall ; from this diverticulum the so-called stercoral pocket of the adult is formed. The lateral nerve cords are finally ap- Proximated in the middle line, and the posterior or abdominal Portion of the nervous system degenerates. The poison glands appear as groups of enlarged cells at the bases of the chelicere. The spinning glands develop from the ectoderm in the region on the ventral side of the proctodzum. e lungs arise as -infoldings from a large oval pair of masses of cells, the nuclei of which are arranged in parallel lines. From these cells the lamalla of the lungs are formed. The heart remains open low for a time, communicating freely with the yolk. The aorta, at a later period, is constricted off from the mesenteron. At least two pairs of the provisional appendages on the abdomen Are modified into the spinning mammillz. The remnant of the upwardly flexed tail persists for some time as a postanal knob; its tip represents the morphological end of the body. € eyes are developed as invaginations of the ectoderm (hypo- dermis). The retinal involution becomes constricted off from the pe csenmn entirely, and then lies just below that portion of the ypodermis which afterwards becomes the vitreous body. In a concave depression, on the surface of the latter, the lens arises as à lenticular thickening of the cuticula, The mode in which the i traverses the eye is essentially similar to the method in raich the light reaches the percipient elements of the retina in © Vertebrate eye.

He finds the ungual phalanges at this period to differ entirely from that of the adult. Instead of being long and claw-shaped, they are wide and _ hoof-shaped, with a trilobate margin, as in the ex- tinct genus Gyptodon. This is highly interesting as exhibiting the law of acceleration modifying that of heredity. The sexual characters are probably like those of the hyznas, in that the female foetus has a clitoris so large as to give her a close resem- blance to the male—Z. D. Cope. ; PSYCHOLOGY. GAMBETTA’S Brain—The Revue recently (November 21st, 1885) gave the weight of Gambetta’s brain, according to M. A. Bloch. This weight, which was remarkably light (1160 grammes), evidently ought to be considered as an entirely secondary element in a proper estimate of the diverse qualities of the organ. At a recent session of the Society of Anthropology (March 18) Pro- fessor Mathias Duval communicated a very interesting report M which he brought out and gave their due value to certain struc tural details of this brain—to certain characteristic elements which must be regarded as far outweighing the simple consideration of the gross weight of the organ. Compared with the brains of in- dividuals known to have been possessed of but little intelligence, and representing types of reduction of the third frontal convolu- 3 tion, the brain of Gambetta, besides other peculiarities, shows a type of extreme development of that convolution. This devel a opment is such that not only are the secondary convolutions more ~- numerous and more complicated than those of ordinary brains, But, besides this, the “ cape” is double. BS ~ This development is evidently in favor of the localization as covered by Broca, who held that the third frontal convolution he , the seat of speech: M.

Very many of them, though | not all, found their way back to their nests, and as a rule reached home sooner than the author did himself. The author noticed that at his summer residence, where he had kept numerous hives of these bees, the following spring many in- dividuals appeared, and seemed to be searching for their previous uals of the previous broods or.not. Towards the close of July, 1884, he obtained three nests of Bombus mastrucatus, a large spe- cies only found in the mountains, and especially the higher re- gions, and carried them to his residence in the city, where he placed them in a window of the second story. The house was en- closed by high buildings, with no garden attached, and yet they returned readily and directly from their excursions to their nests. They throve, and by the first of October had increased to con- siderable numbers. By the middle of October they wholly disap- peared; but in the early part of the following April, individuals of this species were observed flying about the window, and as soon as they found an entrance, sought the remains of their old “nests, and took up their abode. They remained fora while, when their nest was accidentally injured, and they left. Nothing more was seen of them till after the author’s return from his summer vacation, in the middle of September, when a single female of this species made its appearance.

I have often seen these birds dart down into the grass from those heights and seize an insect with such pre- cision that it must have been plainly visible from where the start was made. This would indicate that they possess a faculty of sight, developed by ages of practice, altogether above that of the human race, and most useful in their struggle for existence. But the late Robert Kennicott (quoted by Baird, Brewer and Ridg- way in their great work on the Birds of North America) states that a pair of a wrens will capture 1000 insects per day during the breeding season, and this fact of itself would indicate the sharpest vision and wonderful celerity of movement—Charles Aldrich, Webster City, lowa, Fune rst, 1886.

The Davenport Academy is one of the most thriving State associa- tions for research and collection of material. In some particulars - the museum vies even with that of the Smithsonian Institution. There are in all this vast treasure five objects which run the whole gamut of reputation, from that of base fraud to the high- est credibility. President Putnam gives the history of their acquisition as follows: a. The discovery of two inscribed tablets in Mound 3, on Cook’s farm, near Daven- port, by Jacob Gass, L. H. Willrodt and H. S.

VOCABULARY OF ArCHERY.—In a former number of the Natu- RALIST Mr. John Murdoch kindly furnished us with a vocabulary q of the harpoon. We give below a vocabulary of archery, hoping 3 that all who are in sympathy with us in establishing accurate nomenclature for the various branches of anthropology will aid in adopting these terms, or at least will state their objections if they have any. No claim whatever is made to originality in | most of the terms. Dr. John Evans, the Encyclopaedia Britan- ' nica, Professor Morse, Mr. Murdoch, Hansard and others have : been freely consulted. The list of words given below includes 3 the bow, the arrow and the arrow-maker’s outfit.

Volumes have been written on the subject, and many 4 More will be written before either the subject or the public is r exhausted, My object this evening is not to speak of the nests , of the ants so much as of their inhabitants. These are, of course, Primarily the ants themselves, and by disturbing a moderate-sized nest of any of our larger species, the observer will become | ily convinced that the population is not a small one. But not — ants alone are found in these nests—there is a very distinct fauna that lives with, and perhaps partly on, the ants, and the species of ~ which are never found elsewhere. ae Many hundreds of specimens, principally of Coleoptera, are a found in them, and in Europe nests have been found where © oc the intruders or guests exceeded in numbers the ants themselves.

There is a reason for that too.

Collecting thus becomes difficult, and the result is that comparatively little is known of our myrmecophilous fauna. It is too early, therefore, to undertake anything like a complete list of species, and only a brief sketch of what an ant heap often contains is given. Five groups of myrmecophilous insects can be recognized. First. Those insects captured by the ants and brought into their nests as part of their source of food supply. Second. Species found in the nests only in the larval state. Third. Insects found in the imago or perfect state in the nests, about the larva of which nothing is known. l _ Fourth. Species often found in ants’ nests, but also occurring elsewhere. Fifth. True parasites on the ants, that feed upon their host or its larva. _ In the first group—those insects which the ants collect and care for—the Aphides play an important part. It is well known that the ants seek the plant-lice and lick the sweet excretions; but it is less known, perhaps, that they also collect and rear some = Species, providing homes for them. = A yellow species of Lasius, occurring commonly in the = vicinity of Washington and New York, well illustrates this \ group. The ants make their nests under large stones and close _ to the roots of trees or shrubs. They carefully excavate galleries : around a root or series of roots, and then collect the winter eggs of a species of Pemphigus in large numbers—not by hundreds © out by thousands—eggs that no entomologist has yet succeeded - in ing. These are carefully placed in suitable stami _ around the cleaned root, and the Pemphigus, when hatched, fin _ their food supply ready at hand, and in return are expected to yield sweets to the ants. The winged form of this species leaves the nest and provides for a continuation of the race, and the ants are then compelled to lay in a new supply of eggs. It would be supposed that the ants would be very careful to > out all enemies of these, their domestic animals; but than 1886] Ants Nests and their Inhabitants. 681 is one species that gets in and remains in undisturbed. It is the larva of a common “ lady bird,” Brachyacantha ursina. Unlike ' the larvae of Coccinellids that prey on arboreal species, this is not brightly colored but sordid whitish-yellow. It is of the usual form of these larve, but secretes a waxy substance that exudes in long strings and gives the insect the appearance of being covered with cotton or hoar frost. This secretion seems to be much more palatable to the ants than that of the Pemphi- gus, and they unconcernedly see the Coccinelid feasting upon the former, apparently concluding that the flavor is improved by pass- ing through the latter. Another larger homopterous species is also found in nests of Formica integra, but whether this is used in the same way as the Pemphigus is not known. Sometimes it happens that a desired species will not live under ground, and this compels the ants to adopt another method, mentioned by Patton some years since. They construct roads to the trees inhabited by the Aphids, and build galleries around the plant-lice, effectually protecting and domesticating them. In this category should come those species of ants which are | enslaved by the owners of the nest. The history of that species which captures ants of other species, reduces them to slavery and comes so absolutely dependent upon its slaves that it perishes from hunger if they are taken away, is well known, and offers one of the most interesting phases of insect economy. It is only mentioned here to complete the category, aos The second group, containing those insects found in the nests only in the larval state, is a peculiar one, containing insects of several orders. One of our earliest beetles, Cetonia hirtipes, lives — exclusively in ants’ nests in its larval state; But as imago flies : about and feeds on the sweet sap of trees, or in fall upon ripe — In Europe allied species of Cetonia have similar habits. _ the other Chrysomelids and are found on leaves. ae It is worthy of remark, perhaps, that all these Chrysomelid larvae thus far found with ants belong to that group which con- nies hard cases of excrementitious matter for their protection. — ~“ Would seem that the difference in habit between the e: do 682 Ants’ Nests and their Inhabitants. [August, leaf-feeding species and the protected subterranean feeders would _ have produced either a modification of the sack or have caused its loss in the latter case, but there is no essential difference be- tween those living above and those living under ground, The odd-looking, spinous larva of Microdon, a dipterous spe- cies which has been twice described as a mollusk, is also found here only, while the flies themselves sport in the sunshine as do the others of their kind. A number of other Diptera larva are also found, many of them still undetermined. | Even the Lepidoptera have a representative here, and the larva of Helia americalis is found in the nests of Formica integra in great abundance. What purpose these larve serve in the economy of the nest, and what they feed on, isa mystery. Why the soft, fat coleop- _terous and dipterous larvæ are not devoured by the ants, is still to be discovered. The present theory is, that they feed upon the decaying or fermenting vegetable matter in the nest, and being thus useful as scavengers, are tolerated by their hosts. The mature insects seem to be of no use to the ants, and they make no effort to retain them. The third group, containing insects that are found in the ants’ nests in the perfect stage and nowhere else, is by far the most _ humerous. It comprises species of many orders and of widely _ divergent families, the Coleoptera being largely in the majority as = yet. A few of these true myrmecophilous species have been = found in all stages. Mr. Schwarz has found Euparia castanea m the nest of Solenopsis xyloni, a small ant not one-twentieth of the bulk of its guest, and making small hills only. The upper portion of the hilt is sometimes packed full of the beetles, and in _ the lower stories are found the larve. wes - Most of the species are known in the imago state only, and it _ has long been and is still a puzzle te entomologists where the 1m- _ Mature states of these insects are passed.

Those species from which it is tol- erably certain that the ants derive some benefit; and 4. Those of which nothing at all is known. The only benefit that is known to be derived by the ants from any of the species is in the shape of a (probably) sweet secretion. Prominent among these are the species of Cremastochilus, most of them of immense size compared to that of the ants with which they live. These insects have a glandiferous surface at the hind angle of the thorax covered with a thin plate, and several specimens have been observed where this plate has been gnawed off by the ants to facilitate their getting at the secretion of the glands. These species, as stated, are of large size, and whole squads of ants have been observed in the task of prevent- ing the escape of an individual that had apparently become tired of its quarters. This practice of the ants has been but recently discovered, and nearly created a new species. The hind angles of the thorax are characteristic in form, and systematists have used them to sepa- tate the species. When the first specimen was found without any _ : angles at all, of course it was thought that here was an entirely de new species, and only the fortunate discovery of other specimens in which the angles were only partially eaten off, or missing only 4 on one side, prevented a synonym or two. : : There is an immense difficulty in the way of getting at the | habits of these inquilines. Not only is it a difficult task in the | first place to find them, but when the nests are disturbed every- Ys thing is thrown out of its usual course, and ants and guests dis- appear in the same galleries under ground, from which it is impos- _ sible to dislodge them. Artificial nests have been constructed in Europe, and it has been observed that the ants appeared to lick certain bristly tufts in Claviger, which have been assumed to be Secretory organs. A number of the species in our fauna have sim- "ar tufts and they probably serve a similar purpose. They appear — in all parts of the body and are very variable in extent. Many spe- cies, however, still remain about which absolutely nothing is known, and which have no structures which may be assumed to be Secretory. Many years ago it was observed that Claviger was ix,

Their most ex- tensive breeding grounds in New Jersey are well-nigh deserted during severe weather. ; The popular local notion that crows all “go to Jersey to roost” and return to Pennsylvania to forage, while far from correct, has | more truth in it than the average Jerseyman will admit. i The pine barrens and swamps of the interior afford but scant : subsistence in winter, though providing ample summer accommo- i dation to thousands, while on the other hand, the cultivated and more fertile portions of Delaware, Maryland, East Pennsylvania and West Jersey present an abundant winter supply of food- stuffs, Another important factor in their choice of this district as a winter resort can best be understood by reference to the map, where it will be seen that nowhere on the Atlantic coast are the p geographical conditions, both physical and climatic, more favor- í able to a supply of animal and vegetable food than in the four : southernmost Middle States, whose wealth of bays, rivers, creeks _ and estuaries is unsurpassed in the United States. _ The main object of this paper shall be to give a description of their nightly rendezvous, or “ roosts,” at this season of yeu in the afore-mentioned districts, adding thereto such deductions as are presented by a study of the history of such places, together with observations respecting the habits of crows before and after assembling at their roosting grounds. _It should be borne in mind by those unacquainted with the locality described, that it not only is preéminently a good feeding ground, but that it also furnishes, in the evergreen forests which skirt the shores of Delaware and Chesapeake bays and oe numberless tributaries, a no less suitable shelter wherein to pass the night, | ti a The literature of crow roosts is scant, modern ornitholog — having virtually kept silence respecting this interesting phat 9 d-life, yee _ Wilson’s description is probably the first published one avail- — able.

It is there known by the name of the Pea Patch, and is a low, flat, alluvial spot of a few acres, elevated but little above high-water mark and covered with a thick growth of reeds. This appears to be the grand rendezvous or head- quarters of the greater part of the crows within forty or fifty miles of the spot. It is entirely destitute of trees, the crows alighting and nestling among the reeds, which by these means are broken down and matted together.” He continues: “ The strong attachment of the crows to this spot may be illustrated by the following circumstance; Some years ago a sudden and violent north-east storm came on during the night and the tide, rising to an uncommon height, inundated the whole island. The darkness of the night, the suddenness and violence of the storm and the incessant torrents of rain that fell, it is supposed, so in- timidated the crows that they did not attempt to escape and almost all perished. Thousands of them were seen next day floating in the river, and the wind, shifting to the north-west, drove their dead bodies to the Jersey side, where for miles they blackened the whole shore. This disaster, however, seems long ago to have been repaired, for they now congregate on the Pea Patch in as immense multitudes as ever.” This account reférs to some period in the last decade of the eighteenth century. In a foot-note to this we have the following, . which appeared in a newspaper of the locality about the year 7 1800: “The farmers of Red Lion Hundred held a meeting at the village of St. Georges, in the State of Delaware, to receive proposals of John Deputy on a plan of banishing or destroying Ws ot 8 ha “Mr. Deputy proposes that for $500 he will engage to kill or- banish the crows from their roost on the Pea Patch and giye Security to return the money on failure.” Iam unable to find any other account of this remarkable roost, and am tempted to Suppose that Deputy accomplished the herculean task and outdid the tempest and the deluge.

Sh _ Audubon relates, in his “ Biography,” a few particulars respect- ing the roosting of both species of crow (C. ossifragus and C. americanus), which appear as much based on Wilson’s observa- _ 694. Crow Roosts and Roosting Crows. [August, tions as upon his own experience. They are as follows: “At the same season (autumn) they (crows) retire in immense num- bers to roost by the margins of ponds, lakes and rivers, covered with a luxurious growth of rank weeds or cat-tails, They may be seen proceeding to such places more than an hour before sunset, in long, straggling lines and in silence, and are joined by the grackles, starlings and reed-birds, while the fish-crows retire from the very same parts to the interior of the woods, many miles distant from any shores.” In his “Manual” we find Nuttall quoting from Wilson’s ac- es count, adding thereto additional information of a roost on Reedy island, in the River Delaware. By far the most complete and reliable account of the roosting habit of our crow is to be found in a little work entitled “ Rambles ofa Naturalist,” by Dr. John Godman, who at one time filled the ` chair of anatomy at Rutger’s College. ; _ Godman resided, about the year 1825, as country physician in Anne Arundel county, Maryland, which place afforded him ample opportunity for observing every phase of crow life throughout ` the year. Perhaps the best introduction I can give to the crow- t the night, will be in his words : . “ About a quarter of a mile above the house I lived in, on Curtis’s creek, the shore was a sand-bank or bluff twenty va thirty feet high, crowned with a dense young pine forest to m very edge.

As the sun became entirely sunk below the horizon the grand flock crossed to the sand-bluff on the opposite side, where they generally spent a few moments in picking up a further supply of gravel, and then arising in dense and ample column they sought their habitual roost in the deep entanglements of the distant pines. t Dr. Godman, after describing some of the methods employed a by professional crow-hunters to secure these outlawed birds be- cause of the price set on their heads by the State of Maryland during the years 1800 to 1804, inclusive, continues : “ But the grand harvest of crow-heads was derived from the invasion of their dormitories, which are well worthy a particular description and should be visited by every one who wishes to orm a proper idea of the number of these birds that may be accumulated in a single district. The roost is most commonly the densest pine thicket that can be found, generally at no great . distance from some river, bay or other sheet of water which is + the last to freeze, or rarely is altogether frozen. To such a roost the crows which are, during the day time, scattered over perhaps more than a hundred miles of circumference, wing their way every afternoon and arrive shortly after sunset. - “ Endless columns pour in from various quarters, and as the arrive pitch upon their accustomed perches, crowding closely to- gether for the benefit of the warmth and shelter afforded by the thick foliage of the pine. The trees are literally bent by their weight, and the ground is covered for many feet in depth by their- dung, which by its gradual fermention must also tend to increase n the warmth of the roost.

All being at their posts, the firing was commenced by those most advantageously posted, and followed up successively by the others as the affrighted crows sought refuge in their vicinity. On every side the carnage then raged fiercely, and there can scarcely be conceived a more forcible idea of the hor- rors of a battle than such a scene afforded. “The crows screaming with the fright and pain of wounds, the loud, deep roar produced by the raising of their whole number in the air, the incessant flashing and thundering of the guns and , the shouts of their eager destroyers, all produced an effect which can never be forgotten by any one who has witnessed it, nor can it well be adequately comprehended by those who have not. “ Blinded by the blaze of the powder and bewildered by the thicker darkness that ensues, the crows rise and settle again at a short distance without being able to withdraw from the field of danger; and the sanguinary work is continued until the shooters are fatigued or the approach of daylight gives the survivors 4 DO oF ESCE E ea a “ During hard winters the crows suffer severely and perish in considerable numbers from hunger, though they endure a won- derful degree of abstinence without injury.

Let us now n from this glance at the past, to a consideration of the pres- ent history of crow roosts in the Middle States. My inquiries and correspondence regarding the Pea Patch roost, so far, result in nothing of interest further than the bare fact of the crows not having used that island within the memory _of those whom I have addressed, nor have they even so a heard of this roosting place, but all referred to Reedy islang ing the only like resort in the locality.

Fortifications were begun there in the year 1814, and in 1860 the fort was greatly strengthened and became for the first time a place of importance. Summing up these facts I am led, in the absence of direct evidence, to believe that this noted roost was abandoned soon after the construction of Ft. Delaware was begun in 1814, and that the crows betook themselves to Reedy island as the most convenient substitute. John Deputy’s plan, whatever that was, of banishing the crows from their favorite island may have been successful ere the place became Ft: Delaware, but in case of his probable failure we may — safely suppose an idle garrison of United States troops were not slow to improve their peculiar opportunities for rifle practice and midnight massacre on these feathered aborigines.

[August, island and to sleep secure from the nocturnal prowlers of the mainland pines. To this decade we must revert for reasons which could not agree with the advanced civilization of a later century. But while we may account thus for the original impulse, wherefore should there be such provincialism among a few when there was ample chance and territory for the many to do likewise ? Were the Pea Patch and Reedy island crows Spartans or Helots in the corvine commonwealth? Did they transmit their predilections from father to son, or was caste determined by the query : “ How do-you roost, on Pea Patch island or in a tree Pe This may seem as mere child’s prattle, yet it is worthy of | serious conjecture, to say the least, whether sectional family traits | are transmitted and obeyed by succeeding generations with as blind devotion and prejudice in birds as in man himself. Indeed, _ instances of heredity in tastes and anomalous predilections in the brute world are frequent and indisputable facts. As to their con- y tinuance through time until distinctive traits become gradually _ of generic consequence, we may well defer conjecture and await a more decisive answer in the future developments of scientific research. : Apropos of this question we may just here consider anothe | _ not wholly dissimilar, relating to the subject in hand and, as will -~ beseen, involving the general principles of migration. : My residence is situated exactly in the track of the principal a _ flight of crows which fly, evening and morning, to and from thor roost, five miles distant and which is located near Merchantville, - Camden county, New Jersey. n =- On a windy evening the birds fly very low, as they pass over : open fields nearly brushing the surface of the ground with their _ wings. ther, On the west side of the house stretches a belt of woodland separated therefrom by an open field which the crows always tra- verse in their eastward course at night. This woodland is narrow, and as they approach its western boundary each crow elevates its n flight sufficiently to pass among the tree-tops, and then imme- diately descends to a former level on reaching my field of pee vation.

They appeared in long, straggling lines which were often separated by a distance of a quarter or half mile, and came along in detachments, each of which, as is always t the case in such weather, maintained the utmost silence. Having observed that the line taken by a certain detachment was not more than twenty feet in breadth, and that the whole com- pany passed between certain shocks of corn, I felt curious to see the course of the next, which as yet had not appeared above the tree-tops. After the lapse of half a minute a solitary crow ap- peared, closely followed by three more, and all in like manner and with the common consent of a pack of hounds on the hot trail, pursued the invisible course of their predecessors among the trees, closed their pinions and stooped, as the others had done regardless of the buffeting winds, to the self-same track across the corn-field, and followed it. If every stone and shock and corn-stub had been a finger-post to mark the path of com- pany A to Merchantville, those four sable pilgrims of company B could not have traversed “the desert and illimitable air” with more undeviating certainty nor have hada more unerring foresightof that Mecca of their weary hopes. Long did I watch this mysterious phenomenon, till darkness drew the veil. In miniature, thought [, have I seen a great and mystic phase of nature; migration ina nutshell. Now that we have something tangible to hammer at, let us seek the power and means to crack it and extract that ker- nel, long coveted by man; contented no longer to assign the a honor of cracking such to a “future generation.” A pack of hounds, closely following the scent, presents a tangible relation — to the mind. We can conceive of an odor that touches earth — and of olfactory powers sufficient to trace. it thus, though we 7 Ourselves possess them not; nay further, we can comprehend the canine ability to scent, through sole medium of the atmosphere, — across trackless districts and great distances, and now-a-days we should no longer hesitate to ascribe similar powers to vulturine birds, which in addition possess a wondrous gift of vision. May _ We deny the /atter to the crow or dispute that the former sense is Not only of every-day use to him (though ina modified degree) _ à- , ; 700 Crow Roosts and Roosting Crows. [August, but also to all birds. Not that I would infer that power of scent is of any considerable value in the migration of birds, nor would it be fair to assume that unaided vision is more than a prime factor therein. ’Tis mortal to take our observations from a human standpoint and refer all that goes beyond /#max attainment in the lower ani- mals to “instinct.” Research in natural science as long since paid full penalty for _ her sins in this purgatory of original thought, and the time has fully come for us to advance into a higher sphere, querying the “ what” and the “ why ” in the Emersonian assurance that “ un- doubtedly we have no questions to ask which are unanswer- able.” Phrenologically considered the crow has an excessive “bump” for locality in one corner of his wonderful memory, and size, color (?), form and calculation cluster about his knowing eyes. No less than Audubon long ago professed to have discovered that a crow can count five. Have modern ornithologists done as much ? Be this as it may, we have in our corvine methods of flight an important premise for the final understanding of the laws govern- ing migration and of the so-called migratory “ instinct,” which is nothing more or less than the highly perfected sense or union of senses which enables migrants to traverse tracts of territory (which the uncultured, imperfect mind of man calls illimitable) with a precision which equals that of the wandering crow 1M _ finding its roost, or which a man exercises on a still smaller scale in the streets of his native town. A North American Indian can form a far better conception of ‘migration than a Yankee could, inasmuch as the former is by all odds the better explorer of trackless forests and boundless præ- _ ties. Would we have a “bird’s-eye view ” of this subject? Thea by all means let us “take wings of fancy and ascend” to a point without the earth, though it be merely to understand how 4 place may be so far off “as the crow flies.” yee As yet our unfaith in aérial conquests has kept this inquiry m onomic ornithology at a stand-still; but the spirit of Danns ig Green is again at work; may its leaven work mightily in the fforts of the A.

It seems more probable that it was located either on Burlington island or on the mainland near the site of the city of Burlington, in New Jersey. Twenty years ago a colony of crows roosted on Newbold’s island in the Delaware river, four miles north-west of Burlington island, and forty or fifty years ago another colony slept in a wood near Florence and, being disturbed, moved to another forest near Beverly which, within three years, has been deserted in turn for another site. There is much to warrant the conclusion that the great roost described by Wilson was parent to this and many others now Scattered over Burlington county, New Jersey. (To be continued.) 10: THE WINGS OF BIRDS. BY I, LANCASTER. Wile engaged in ascertaining the methods employed by the soaring birds, on reaching a point where light began to break upon the obscurity, it became evident that the flight of all birds would be made comprehensible; that not only the day-long translation of frigate birds in ‘circular paths high in the air, but _ the homeward passage of pigeons and the migratory flight of wild fowl, would emerge from the realm of fancy and range themselves with allied phenomena on the platform of recognized _ mechanical activities, Indeed, many specimens of active wing flight have hitherto as _ : completely baffled the best efforts of mechanical science as has Soaring flight. When the weight of the bird is considered as- resistance to be overcome by muscular force, flapping is incompe-— tent to do the work required, and in spite of such effort gravity Would compel motion in its own direction to the surface of the - The area of the two wings of a duck of four pounds weight, _ which is effective on the air in the down stroke is not more than e _ two square feet.

If this velocity be transferred to the wing vibration, stability of the body could only be secured by a rapidity of stroke ten times as great as what actually occurs, But when we add the air resistance to lateral motion of, say one hun- dred miles an hour, measured by air passing the bird, its muscu- lar exertion becomes still more incompetent to effect the result, for now a portion of the energy which before was used to antago- _ nize gravity must antagonize air resistance. Further load is thus added to the working force, which before ia was hopelessly incompetent to its task. No method which is ; supposed to differ from the direct motion will assist in the least. It is velocity which is wanting, As there can be no shorter line = between two points than a straight line, so there can be no more : effective method than continuous motion, normal to the surface, with no change whatever in the ‘character of the activities. A _ continuance of the maximum is the height of effectiveness. No _ Screw motion, or wave motion, or figure-eight motion, which e wing may imitate, can produce results as good as the direct motion. But bird flight thus conceived does not exist in nature. Ast fact, gravity is not resistance but motive power. The bird is a _ machine doing work on air under the dominion of that force. The work done is not the sustained bird but the quantity of a ‘4 disturbance which falls tó an equilibrium with the surrounding es atmosphere after the passage of the moving body through Eo Gravity is not resisted, it is resolved. The bird is constantly moving in the direction of the normal component with a uniform _ velocity which develops air pressure sufficient to neutralize the mponent acting in the plane of the wings and the additional face friction of the air. The direction of the fall is that of the gravity of the bird’s mass, and this direction changes with the ant of the wings, being always at right angles thereto in obe- : to the law of fluid pressures. The fall is always away from See Ci eee Ee S Spe es " r l PIERS aos eam eae + y i EF rt A A EE rivet A LM ak Rea eii She ete Se, 1886. ] The Wings of Birds. 703 the plane of the wings, or the bird’s horizon, so that no weight is lifted in the lateral motion, as the body is continually descend- ing on its own vertical. This view completely transforms the aspect of atmospheric navigation, and brings order out of chaos. I have hitherto spoken of the expansion of the compressed air in the rear of the wings producing the thrust needed for the lat- eral motion. This was done to avoid complicating the case. The significant thing is the resolution of gravity and consequent shifting of the vertical, and if this fact is seen the method of utilizing the pressures presents no difficulty. I now wish to direct attention to the structure of a bird’s wing, The wing of a pigeon or any of the barnyard fowls may be ex- amined, as the peculiarities I desire to point out are found in all of the large birds. First, let us examine a feather. If we place one on the table with the lower surface upwards and pass the 7 _hand from the quill to the tip, it will seem smooth to the touch, + while reverse motion meets with much roughness, which in- creases as the pressure of the fingers becomes greater. If a small tube be taken into the mouth and the breath blown quite slanting towards the tip, the feather will remain smooth and the air slip over it easily. In the reverse direction the blast will tend to open the ribs and increase the roughness. The feather is a little like a cat’s back ; a rub toward the rear is pleasant to all parties, while one the other way tends to cause motion of the ani- mal to the front. Notice also that the tip is very thin and elastic, yielding in a graceful curve to slight pressure. The surface of the wing is composed mainly of these feathers, having their general i direction across, with the tips to the rear. They aré held by the integument covering the bones of the wing, which are located on the front edge, and while on the upper front side the curve is- smooth and regularly rounded, beneath there is a projection downwards of the skin, which forms a ledge reaching along the humerus to the elbow and thence to the junction of the ulna and _ Tadius with the bones of the wrist, being greatest at the elbow. Tn the Soaring birds this ledge is largely developed, projecting — Wards in the frigate birds one and one-half inches at the- elbow, tapering to the wrist and body. This ledge, at the front — edge of the wing, seems at first view to be an obstruction to- flight, as it makes considerable thickness where the surface first — ‘Meets the air, but, as we shall presently see, it has an important — 704 The Wings of Birds. [August, function to perform as a member of the organized mechanism of flight. The curves in the plane of the wing need not be consid- ered as they are not concerned with flight, and when the bird is in the act of flying they are straightened out so that the wing assumes a plane shape. The above four peculiarities we desire to note. Firstly, that the wing is practically a thin plane. Sec- ondly, that its rear edge is very pliable and elastic. Thirdly, that its under surface is rough to motion from rear to front but smooth to motion from front to rear. Fourthly, that it is supplied with a ledge along its under surface at the front edge. Let us now attend to a matter of simple experiment, which demonstrates bird flight as I have presented it in the pages of this magazine, and which connects the above-described con- struction of a wing, which is the organ of flight, with the mechanical forces which are operative upon it. A few cents worth of material and the expenditure of a little time is required, a which, coupled with a minimum of mechanical expertness, will = suffice. The movements following changes made in the plane are _ So prompt and emphatic that there is no mistaking them. If we take a sheet of light, strong paper, such as goes into the construction of fireworks, and stretch sixteen by forty inches of it tightly on thin strips of bamboo, so as to present a plane surface on _ one side, and fasten a four-ounce weight in the center beneath by threads to the four corners, we will have a miniature parachute. By putting its upper surface against the ceiling and permitting p to fall, it will descend vertically if we have it well balanced. It is = Obvious that the entire column of air from the ceiling to the floor ing. Hence the zone of air under the plane, acted upon by it, _ would be pyramid-shaped with a base sixteen by forty inches, a _ top line twenty-four inches long and a height varying with the ward, and there would be a steady flow or slipping of the com pressed air along the surface in all directions from the center. like in all directions no lateral motion would occur. If we now take some lar: ge-grained, light sawdust and mucilage, and thinly ‘le one-half of the under surface from one of the long edges _ velocity of the fall of the plane, with the apex pointing down- his slipping would cause friction on the surface, which being The Wings of Birds. 708 : to the center, the level plane will no longer fall vertically but : move towards the edge bounding the sawdusted half. If we i extend the paper an inch over the edge opposite the saw- dust and snip it into the bamboo so that it will curve upwards, : we shall find on dropping the plane that its sideways motion will 4 be augmented. If we paste a slip of paper to the front edge, allowing it to project one and one-half inches beneath, we shall ‘ find the sideways motion to be further increased so as to be many 2 times that of the fall. If we take the plane to the housetop when the air is calm and allow it to drop, it will describe a curve while itis being accelerated, but on uniform motion occurring it will slant downwards very gently and move laterally from six to eight times as fast as it falls vertically. This experiment is very deli- cate and the motion varies greatly, depending on the weight and humidity of the air and the construction of the plane. The cause of this behavior is obvious. The air in rushing along the under side of the plane to escape, drags the rough surface with it i to the front, slipping over the smooth part to the rear easily. f Then as it turns the curve it expands against it, augmenting the front , thrust. Where the air escaping toward the front meets the ledge, a Complete stoppage occurs, and the thrust against it is quite vio- : lent. The ledge in front of the roughened half of the surface, and : the rear curve, all tend to throw the plane edgeways in the same i direction while it falls. The ledge by directly stopping the mo- = tion of the rushing air ; the rough surface by frictional resistance, and the curve by presenting a base for the compressed air to ~ Xpand against. The force required to produce these various results is put into the air by the descent of the plane upon it under the impulse of the gravity of its mass. The wing of a bird would act in the same way that the plane acts, and for the Same reason. The elastic feather tips give the curve. The con- Struction of the feather surfaces gives the smooth rear and rough > front part; and the front projection of the integument covering _ the bones forms the ledge. : + it falls ? Obviously because the condensed air in contact with a: the surface moves with far higher velocity than the fall, carrying the plane with it. The inertia of the air resists sudden motion So that the particles are compressed before they begin to move, Why is it that the plane moves so much faster edgeways than — ~ [August, and when motion at length occurs, it is sufficiently rapid to make up for lost time. A non-elastic fluid would not present this rapid motion on the compressing surfaces. If we increase the pendant weight and take the plane to the lantern of a lighthouse, or very high building, we shall find that its lateral motion will be greater, and every addition of weight will heighten the lateral velocity in a greater ratio than the fall. The reason is that the plane meets with small resistance to its edgeways motion, so that a slight increase of force in this direction moves it rapidly. But however great this motion may be, however closely it may ap- proach level translation, by no means could it become horizontal as long as the plane itself was level. The entire force producing lateral motion comes from motion in the direction of gravity down the vertical, and horizontal translation would stop the fall, thus cutting off the motive power. But if we slant the plane the vertical goes over with it. Its own activity determines the direc- tien of its vertical. It is fluid pressures we are dealing with, and what would be level translation on our horizontal is a constant fall from the bird’s horizontal, and a soaring bird certainly needs : no further explanation, neither does a wild duck. Itis not heavy = enough relatively to the size of its wings to reach a uniform velocity of fall which would produce the thrust needed in the lat- eral motion, and resort to flapping is compelled to aid the normal _ component of gravity. The wing now comes down with velocity = sufficient to give the thrust required for horizontal flight. But _ both soaring and flapping would be impotent without the resolu- _ tion of the direction of gravity. _ The moment the plane is inclined it becomes necessary to _ counteract the component of resolved gravity acting in it, op the 706 The Wings of Birds. ous man could move his limbs at a higher speed than mint feet per second for a short time at his utmost exertion. a planes greatly exceed this velocity in the lateral motio®, © 1886.] The Wings of Birds. 707 soaring birds moving at times at the rate of 150 feet per second, Motion of the planes, therefore, is best derived from their own activities. This can readily be obtained in still air by using fine shot for the weight in an oil-silk bag with a thin neck opening into another placed lower and fastened to the corners of the plane by separate strings. The neck should be made to allow two pounds of shot to flow through it in about ten seconds; as the shot reached the lower bag the plane would be slanted by draw- ing on the longer front and shorter rear strings. With 150 feet fall this construction will give motion under the resolution beautifully. Nothing can exceed the graceful curva-. ture of its movements excepting similar ones made by the soar- ing birds. As acceleration passes into uniformity and the total force is expended in the work on air, as the shifting balance in- clines the plane transforming the vertical, ample force is on han in the condensation to resist the downward slanting impulse. If the adjustment is correct, holding the plane on the right incline, horizontal motion will occur until it passes out of sight. More inclination will cause upward slanting direction. If the incline be so great as to throw too much of the resolved gravity into the plane for the forward thrust to cope with, speed will slacken and finally motion to the front will cease and be reversed on the down- ward slant backwards, and the frail machine become a wreck in an instant by violently striking the earth. I have floated these planes from the lantern of Egmont light at the entrance of Tampa bay, on the Gulf coast of Florida, when the air was so still that a handful of down, from the breast of a pelican, thrown from the — top would quietly sink along the shaft to the ground. To one who is familiar with the soaring birds, and has made a study of their habits, these floating planes present little that is _ -iteresting. They imperfectly imitate the birds and do nothing — that the birds can not do better. The latter present a plane with - automatic balance as well as a selfacting steering apparatus, and ; are so plentiful that they can be studied at any time, But the _ Panes serve to explain the wing admirably, and after witnessing — < their performances with none, and either, and all of the contri- vances for producing forward thrust, but little more need be said _ or done explanatory of their functions. _ From the fore-leg of a reptile to this wing is doubtless a long [August, step. It must needs be. The reptile passes life in the midst of solid, non-elastic resistances ; the bird lives a divided life, part of which is under the dominion of other laws, It copes with fluid elastic pressures when it navigates the air, and nature has trans- formed the creature to meet the changed conditions of its exist- ence. One pair of legs is retained to treat with forces under the dominion of laws which operate in the reptile world in common with man’s world, where the sea is level, and vertical forces point to the center of the earth; where motions are deliberate, impedi- ments plenty, clashing activities found on all sides and the area of translation confined to two dimensions only. The other pair are changed to suit a very different world where the sea isa hillside, vertical lines variable, the plane of the horizon perpetually _ changing, impediments non-existing, velocities high and the third dimension added to the area of translation. ; With the organ of flight understood, and the resolving power of planes working on air under the law of fluid pressure com- prehended, there would seem to be no further impediment to the application of the axioms of mechanical science to the problem _of air navigation. 708 Editor’ Table. = F ii 2 eligi FR eet cee fe nee wees eal Fi o——— .

[ August, property of the Government. The objections to this rule are so numerous that we can only give a brief review of them: (1) It restricts the survey to use of a range of material which is narrower than it should be. Much that is contained in private collections, especially in the department of palzontology, is unique, either entirely or partially, and must remain so always, or for a long time. The author then who wishes to present a truly scientific monograph to the survey is unable to do so; and the student must look through the usual variety of publications in order to get a complete report on any subject. This rule, there- fore, destroys the chief merit of government publications, which consists in the fact that they can be, owing to the superior pub- lishing capacity of the Government, more compendious than the _ publications of any private person or society. : Were this rule impartially applied, it would greatly curtail the ` value of the government publications, but as it is only used with reference to certain persons, its full effects are not yet apparent. (2) The rule involves the survey in a great unnecessary €x- - of the country. It involves loss of time in the necessity which results from the new study by persons unfamiliar with it. It in- volves loss of time in the delay which follows the repreparation of new material. It employs men at high salaries to do again work which has already been done. It thus causes waste where economy is highly important. $ : The opposite policy was pursued by the surveys which pre- ceded the present one.

The rise and fall of the tide along the eastern coast is very slight, at Gensan only two feet, while at Chemulpo, on the west coast, there is a rise and fall of thirty- eight feet. From Fusan westwards, and along the west coast, there are numberless islands and mud banks, interfering greatly with navigation. The Amnok is by far the grandest river, but the Tai-dong, Han (on which Soul is situated), Keum and Mok- pho are important. The northern portions of Korea are mountainous and the Scenery fine, but further south the mountains diminish until at length they are but low-lying hills. There are in Soul few houses more than ten feet high, for even the dwellings of the better classes are low. The smallness of the Ouses seems to be compensated by the size and variety of the hats worn by the men. High conical hats, black or white, and of open texture, made of split bamboo, horse-hair, or wicker work, seem to be common, and some of these are topped with a little bee-hive covering of oil-paper to protect them from rain. Drains are unknown in Soul, and the foul mass of decomposing matter lying on each side of the street is never cleaned save by a rain-storm. e houses- are heated by a chamber below the winter rooms, at one side of which is the repository for the fuel, at the other a flue leading to the chimney, which is detached. At the ends of a house are the summer rooms, raised above the Sround on corner-stones. The dwellings are built of wooden pillars Supporting a heavy roof of wooden beams and tiles, The -ters are pared away so as to fit into sockets on the top of the Pillars. The spaces between the posts are filled with masonry, the stones of which are often tied together with millet stalks, on account of the high price of lime. Eight feet by six feet, and five t high, is a good room in a Korean cabin. € road to Wi-ju, on the Amnok, is the high road of com- merce north of Soul, as every track west of the mountains con- verges on it.

Arrica.— Madagascar—aAn interesting account of the geog- raphy of Madagascar, which is claimed frankly as “une terre Frangaise,” is given by M. Georges Richard in the Revue Scien- tifigue of April 3d.. The little explored central mountain mass contains several plateaux, while between the spurs which diverge seaward, and often form a series of platforms, are fertile valleys, watered by streams, few of which are navigable. The most con- siderable of these are on the west side, and are the Onilahy, the Mangoko, the Sigiboujy and the Ikiope and Betsiboke, which unite and débouch in the bay of Bombetok. The mouths of the nvers upon the eastern coast are almost always obstructed by Wet season, so that they form extensive marshes—the source of the Madagascar fever. The climate of the interior is healthy. Algeria —The Revue Scientifique has recently published a series of articles upon the geography of Algeria, from the pen of M. A. LeChatelier.

(August, To the American paleontologist the greatest value of this memoir consists in its descriptions and inferences as to the his- tory of the Artiodactyla. The materials for this study are more limited in America than in Europe. Dr. Schlosser gives full credit to work done and conclusions reached in America. He adopts the views here proposed as to the ancestral position of the Condylarthra; and also the theory of the phylogenies of the teeth and feet of Mammalia proposed by Cope. The only defect in knowledge of American literature we observe, is the case of the report on the vertebrate palzon- tology of Colorado, published in the Annual Report of the U.S. Geol. Survey of the Terrs. for 1873. On this account the char- ` acters of some genera are overlooked. i “here are some positions adopted by the author which we sus- pect that he will modify. Thus his systematic views are different from those which have been usually held, in that he uses phylo- genetic series as identical with taxonomic divisions, and not, so to family which are given (p. 33) are not true of Hyracotherium. _ Although there can be no doubt that this genus is the ancestor of Equus, all taxonomic precision requires that it s ould e placed in a distinct family from that genus, and in company Wit _ genera (e. g., Systemodon) which Dr. Schlosser places (p. 27) in -his Tapiridæ. To illustrate this matter more precisely I e __ the phylogeny of Equus arranged in the family phases throug which it has, in my opinion, passed, and as I have given it: Equus belonging to Equide | Protohippus, éte | i; Anchitherium \ Palzotheriide Lambdotherium “ Chalicotheriidæ | 1886. ] Geology and Paleontology. 721 divisions based on their structure, e. g., Condylarthra, Ambly- oda, “ Paar- und Unpaarhufer.” Within each of the latter he admits bunodont and lophodont forms. It is in the Condylarthra that he hesitated to admit the lophodont form Meniscotherium, and is disposed to place it in the Perissodactyla on account of its dentition; a proceeding in which we cannot agree with him. It is considerations derived from the dentition that lead Dr. Schlos- case with the Bovide, in which Dr. Schlosser regards the robust form Bos as the descendant of the slender Gelocus. Such has Probably been the history of Rhinocerus, which Dr. Schlosser objects to deriving from Hyrachyus on account of the more slender feet of the latter. €re is an important discussion as to the origin of the milk dentition (p. 109). Dr. Schlosser refers to Baume’s hypothesis that the temporary dentition consists of those teeth which have en thrown out of the regular series by the contraction of the regular series. A preferable hypothesis is that of Wortman, which regards the mammalian dentition as following a law of Succession fundamentally that of the reptilian, the reduction con- sisting in nothing but anteroposterior members.! add that Elasmotherium is much more probably derived from Ccelodonta than from Aphelops.

The actual coal-beds do not appear to extend beyond Dong-Trieu, but the strata are more extensive, and it is not unlikely that detached portions of coal -may be found among the hills of arkoses which rise out of the rice-fields of the Delta.

Thin sections show under the microscope a flow structure. Devitrifi- cative products are abundant, while porphyritic crystals are of small sizes, consisting almost entirely of hornblende, magnetite and a brown mica. From a consideration of all the facts and a comparison of similar occurrences of rocks in other localities, the 1 author concludes that the tension which affects large rock masses manifests itself in the structure of the nuclei of perlitic masses. He further observes that the parting which produces columnar structure in rocks owes its origin to the contraction which takes place during cooling. The secondary system of curved cracks which gives rise to perlitic and similar structures are more prob- ably due to the contraction which goes on as the volatile materials which they contain are slowly separated from them. A very im- portant contribution to the subject by regional metamorphism has recently been made by C. R. Van Hise,! who is working with Pro- fessor Irving on the Archæan rock of the Northwestern States. In this article the author gives`in a very condensed form the result of his studies on the rocks of the Penokee-Geogebic iron- bearing series in Wisconsin and Michigan, and promises that a full treatment of the subject will appear later in a memoir by Pro- fessor Irving and himself. This formation extends in a general east and west direction for a distance of eighty miles through parts of Wisconsin and Michigan. It is younger than Kewee- nawan and in its upper members differs in different localities. The group consists principally of mica schists, black mica slates, little clayey matter, perhaps also with a small quantity of frag- mental mica and some feerite. * * * -The quantity of feldspar was apparently considerably greater in rocks of the western part l Upon the origin of the Mica Schists and Black Mica Slates of the Penokes- Geogebic Tron-Bearing Series.

BOTANY.? prepare a (June) of the Botanical Gazette ought to satisfy every demand of the inquirer after the best botanizing methods. The general methods of making specimens are treated in notes and communi- cations from ten different botanists. How to collect certain plants receives the attention of twenty-one specialists. The Gray Herbarium and the National Herbarium are described with some uable series of communications. Perhaps the one fact most Prominently brought out, is that good specimens are made by care and painstaking, rather than by following this or that par- ticular method. The lesson of greatest importance to the be- sinner taught in this herbarium number, is that he must make good specimens.

A Broaper ELementary Borany.—In the schools and col- leges of this country the teaching of elementary botany is still but little improved, however much of change for the better the higher departments may show. In fitting up our labora- tories, providing means for studying cells and tissues, gathering collections of all sorts of materials and specimens, from German herbarium specimens of bacteria to trunks of great trees, we have done well for the classes of somewhat advanced students, but have we not in our zeal for improvement in these lines forgotten or ignored elementary botany. The beginner finds that with all this talk of improved methods he is still obliged to pursue the same old tread-mill course with its endless list of bare technical- ities and meaningless botanical jargon. Beyond his field of ele- mentary work he sees evidence of great activity among pests but /zs work remains almost precisely what it was a score years ago, in spite of the fact that in this period the great science of plants has undergone a complete transformation.

Bourne describes several points in the anatomy of Sphzrotherium, which have been overlooked by previous writers. The genus differs from Glomeris in the position of the antennz in a deep fossa. Corresponding to each of the twenty-one pairs of legs is a pair of “tracheal plates” placed between the attach- ments of the appendages. The first three pairs belong to as many segments, while of the remainder, like the legs, two pairs belong to each segment; there is also a nerve-ganglion to each Segment. In the male there are three extra pairs of appendages, l copulatory in function; two pairs of these bear stridulating organs which have not been previously noticed in this genus; besides the chitinous ridges on these appendages, there are similar ridges on the inner surface of the large terminal tergite. _ The tracheal system differs from that of most other Diplopods in having very well developed branching trachee. Each tracheal plate carries a stigma, which opens into a “tracheal sac.’ rom this Sac two main tracheal trunks pass out, each of which breaks up into a number of smaller branches. The author considers the tracheal sacs homologous with those of Peripatus, from which form these branching trachez are derived. The antennary sense-organs are conspicuous. An error is pointed out in the description of their histology by Bütschli, who | mistook certain cells, in the connective tissue surrounding the nerve bundles, for ganglion-cells. An auditory organ is presup- Po the existence of a stridulating organ. The cavity open- ing to the exterior by a small pore below the eyes is regarded as such an organ; it is lined by a sensory epithelium, supplied by the nerve-fibers from the cerebral ganglion.— Fourn.

GEOGRAPHICAL DISTRIBUTION OF PELAGIC MARINE ANIMALS.— Herr C. Chur (Zool.

The outer margin of the shell, that is the thickened periosteum and the inner surface next the mantle, are always soft. The calcification both of the prismatic and mother-of-pearl layers, is due to small, roundish, irregularly distributed bodies, which gradually increase a in all dimensions and become prismatic by mutual pressure. During the metamorphoses of the young mussel the shell has a fibrillar structure; the lamellation is secondary, probably be- ginning along with the calcification. The original fibrillar struc- ture is associated with the development and differentiation of the shell-muscles. The organic substance of the shell has a cellular origin, In their development the fibrils follow the directions of the mantle-muscles. They assume a radial course at the ligament, but elsewhere run parallel to the surface of the mantle, following the direction of the muscle-fibers which run transversely round the animal, just under the epithelium, and which, uniting with the tooth-pad, the pallial line and the periosteum, thus exert influ- €nce on the fibrils. These transverse muscle-fibers aid in the opening of the shell. Those radially disposed on the back of the animal flatten the ligament in contracting, and thus also aid in opening, as those also do which ascend on each side from the foot, and are at- tached to the tooth or tooth-pad. The muscle-fibers uniting the dorsal muscle insertions on either side, act as adductors. The 7 bundles of cross muscles on the margin of the mantles, which are : by one end attached to the shell on the pallial line, and the other k to the free portion of the periostæum, effect by their contraction the apposition of the soft-shell margins, and a consequent perfect a Closure of the shell.—/Journ.

The motor’ nerves of each muscle spring from the nearest ganglion; but all the inhibitory fibers originate in the anterior ganglia. The latter pass to the anterior adductor by the short nerve-branches which pass to it from the anterior ganglia, They reach the posterior muscle through the connec- tives. The posterior ganglion thus functions as motor center for the posterior adductor; and the anterior ganglia act similarly on the anterior adductor. The motor cells of the ganglia on either side may be stimulated to activity, either by peripheral nerve- fibers (of the mantle or gills) or by certain fibers of the connec- tives. The anterior ganglia are able to produce relaxation in either anterior or posterior adductors.” AsyssaL DECAPOD CRUSTACEA OF THE NORTH ATLANTIC.—Pro- fessor S. J. Smith reports in the Annals and Magazine of Natural History (1886, 187) on the species collected by the Albatross. found at depths below 1000 fathoms. The first question whic arises is, which of these actually inhabited the bottom? Fifteen ' of them—that is the two Brachyura, the seven Anomura, the _ Eryontids, Crangonids and Glyphocrangonide among the Mac- rura—are unquestionably inhabitants of the bottom.

THE SENSE ORGAN IN THE PINEAL GLranp.—The suggestion of s Ahlborn and Rabl. Ruckard that the pineal gland is the remnant : of some organ of special sense present in some primitive Verte- brata,! has received confirmation from the studies of Von Graaf and Spencer. The former finds a rudimental organ of sense in ‘this part of the brain of the slowworm-lizard (Anguis fragilis), and the latter, who works in the biological laboratory of the University of Oxford, finds a similar organ in the Sphenodon punctatus. The organ includes a lense, and is of the invertebrate type, 2. e., the rods are turned towards the light and not away from it. These observations render it probable that certain extinct re- n lations of Sphenodon, the saurians of the family Diadectidæ (order Theromorpha) of the Permian epoch of North America, had this pineal sense-organ highly developed. The frontopariétal fon- tanelle is larger than in any other reptiles, and the cast of the surrounding regions shows various peculiarities (see Proc. Amer. PHIL Soc., 1885, p. 236).

Mitne-EpwArps. — The changes which the young lobster undergoes during the first six or seven weeks of its _ free existence, as a pelagic organism, constitute a veritable met- amorphosis, which is apparently accomplished in the course of six _ ecdyses, or changes of the exoskeletal investment of the body. ese molts, or ecdyses, occur at intervals of from four to fif- teen or more days, if the larve are well fed. At each ecdysis a complete renewal of the exoskeleton occurs; the old cast skin = ng quite thin and transparent up to the fifth ecdysis, and retains the form of the body at the time of molting. The old skin is rup- | oa along the median dorsal line of the cephalothorax and at te point where the latter joins the abdomen; the tail is with- drawn after the head. esos a uch as some Arthropods undergo an ecdysis within the “SS, the advanced eggs of the lobster have been carefully exam- _ med to determine whether a molt took place at the time of - “Edited by JoHN A. RYDER, Smithsonian Institution, Washington, D. C. ey 740 : General Notes. hatching. Such is not the case, since the thin distinct inner mem- brane ruptured at the time of hatching is not a molted larval skin, but an egg-membrane which was developed within the ovary. This egg-membrane is invested at the time of oviposition by a much thicker coating of a viscid substance, which is continued into the flexible threads by which the eggs adhere together in clusters and are suspended to the setæ which fringe the abdom- inal appendages of the adult female. At the time of hatching the young hang for a short time more or less firmly to this inner membrane, grasping it with the rostral spine and telson, The first stage.—This stage is the one which the young lobsters present at the time of hatching. They are essentially Schizopods during this and the succeeding three stages. During this stage the young have no abdominal appendages, and swim about as pelagic larve by the help of the outer rami or exopodites of the ce six hinder cephalothoracic pairs of appendages; the endopodites or inner rami of the six hinder cephalothoracic appendages are : not used in locomotion during this stage, and are almost wholly subservient to the purpose of prehension. The telson is a single, _ very broad, somewhat triangular piece, with strong spines at either | posterior angle. The total length of the larva at this stage is : i eight millimeters. : Second stage—This stage follows the preceding abruptly m ‘Upon its accomplishment the larva has increased 1.5™™ in length, as the young lobster is now 9.5™™ long. The second to the fifth abdominal somites have also acquired appendages. _ Third stage —This follows the preceding, and is preceded by a -second ecdysis about the tenth to the fifteenth day after hatching. -The penultimate or sixth abdominal segment also acquires a pal of biramous, lamellar appendages, which fold alongside of and 1 re- Fraea the telson. The young animal now measures II.5 in - Fourth stage-—This one succeeds the preceding, and is preceded by a third ecdysis on the fourteenth to the eighteenth day a hatching. The young lobster differs but little, except 1m s1z° an _ the proportional strength of the successive pairs of appende from the foregoing stage, and now measures 13™™ in length.

The telson now closely resembles that of the adult, and on either side of it the broad brown in some cases, so that the animal is no longer so trans- Parent as during the preceding stages. Sixth stage-—This stage is attained between five and six weeks after hatching and, like the foregoing, is preceded by —_ The latter, unlike the previous molts, is hard and brittle, bluish in color and retains the form attained by the animal at the end of the preceding stage. The young lobster now measures 19™™ from the tip of the still bifid rostrum to the tip of the telson; 22" from the tips of the extended chelipeds to the end of the abdomen. The antennz are now considerably longer than the cephalothorax, or proportionally almost as long as those of the ~ adult ; the total length of the animal from the tips of the extended — antenne to the end of the telson is now 29™™ One of the chela is now also perceptibly larger than the other.

The pair of appendages on the first dominal ring have now appeared as very short rudiments which ee ESR 3 742 General Notes. [August, are quite unlike those of the adult both in form and size. The modifications of this pair of appendages, indicating the sex of the individual, have not yet appeared, however, and are probably not developed until after the next or seventh molt, when the young lobster entered upon the eighth stage of its free existence. There is a very decided inequality in the size of the two great “claws” or “ pincers” at the end of the seventh stage. The young animal now manifests a more strongly marked disposition to remain on the bottom than during the preceding stage. This last-described stage is attained in about seven weeks after hatching. It will be seen that as to the number of stages my observations are not in accord with those of either Smith or of Dannevig.' The work of G. O. Sars, on the development of the European lobster, I have not seen, but the large amount of material which I have had the opportunity to study in a series of tanks, under conditions admitting of very little chance of error, in the United States Fish Commission station at Wood’s Holl, leads me to think that with the precautions which have been taken, I have not con- founded or subdivided any stages, as I believe an alcoholic series which has been preserved of the stages above described will „amply prove. With a slight rise in the temperature of the water, -and an abundance of food, the fourth molt, or fifth stage, may be rr in twelve days, as later expericnce shows.—/ohn A. J _ THE MONSTROSITIES OBSERVED AMONGST RECENTLY HATCHED LoBSTERS.—At Wood’s Holl a few double monsters were hatched out amongst the normal lobster larvae. These monstrosities were all _ the more interesting from the fact that they proved in the most striking manner that double monsters must be developed in the = meroblastic egg of the lobster in much the same way as in that -of fishes. _ Four forms of double monsters were observed : ‘ h _ First type—This one had no eyes ; the cephalothoraces of the _ two embryos were completely fused together laterally and anteri- orly, while their abdomens were separate and diverged at a wits angle from each other. th __ Second type—This form had a single eye anteriorly and on so line where the cephalothoraces of the two embryos were i together; in other respects this form resembled the preceding. $ -Third type—In this form the cephalothoraces of two eo were fused laterally and anteriorly, and there was no median €y as in the preceding type, but a pair of eyes, the one represo the left eye of the left embryo, and the other the right eye ° right embryo, were developed. b _ Fourth type —In this form the cephalothoraces of two em n se Saltvandsfisk- Beretning over Virksomheden ved Udklaekningsanstalten for ages EAT 1886. | Embryology. 743 were fused together along their anterior dorsal aspects. There were four eyes developed, two to each embryo, and two distinct sets of mouth-parts and biramous, locomotive appendages. In this last form the two embryos adhere together dorsally, and € two systems of limbs of the two nascent lobsters, which have obviously developed from a single blastoderm, enveloping one yolk, are directed away from each other. This relation of two perfectly formed embryos in the same lobster egg is exactly the reverse of that which is observed in vertebrates, For ex- ample, two embryo fishes which had been developed from the same blastoderm would, if primarily formed at exactly opposite sides of the blastodermic disk, finally be found to adhere together by their ventral aspects, so that their backs would look in oppo- site directions. These interesting data may in part be interpreted by the well-known fact that the neural aspect of an arthropod is ventral, while the neural aspect of a vertebrate is dorsal. This does not, however, afford a complete interpretation, since we find, not only in the case of a double vertebrate, but also in that of a similar invertebrate monster, that the median or unpaired organs of the two are often fused. This is the case in the double monsters of the lobster of the first, second and third types. In- asmuch as such structures as the alimentary canals and hearts of two such conjoined embryos are so fused, the question immedi- ately arises, How was this accomplished? The answer seems to be that the fusion took place coincidently with the process of gastrulation and the subsequent gradual formation of the organs of the two embryos. This view of the matter is further substan- tiated by the fact that the four types described represent as many degrees of fusion or union. The question which now arises, how- ever, relates to the way in which these different degrees of fusion of the two embryos were developed. 150 is may be explained, it appears to the writer, on @ rior grounds, in the same way in which the different degrees of fusion or concrescénce of double fish embryos were interpreted by Rauber, and since verified by other observers. That is to say, if two gastrule were developed at the edge of the same blastodisk, 744 General Notes. [August, PSYCHOLOGY. A Curious Suprrstition.—A neighbor, residing on a small farm near me, has, on several occasions, spoken of his experience with “hog mice.” He came to this country many years ago from Northamptonshire, England, where he had often seen these strange animals. They are also occasionally seen by him herein Iowa. This mythical rodent is about the size of a barn mouse, but its striking peculiarity, as to outward appearance, is, that it has a head and face fashioned exactly like that of a hog. It isa very “uncanny ” little beast. If it merely runs across the body of a sleeping person, or of a domestic animal, such unfortunate person or animal will be grievously afflicted with lameness or soreness wherever the mouse sets down one of its little feet! Serious dis- ability often comes from the touch of the “’og mouse.” In some extreme cases the affliction is well-nigh incurable, and may even last a life-time. ae My old friend said that it was no hearsay matter with him. He “had seen ’og mice both in Northamptonshire and ‘ere in Ha- merica.” One of his colts “ was disabled by a’og mouse running hover hit, and was a long, long time getting well.” A striking peculiarity of the hog-faced mus, according to mA old friend, is that it is never seen at rest, but is always “on a dea run,” as if fleeing from pursuit. tl I tried to reason him out of this absurd belief, but he stoutly asserted that he had often seen these animals and witnessed the deleterious effects of their presence; that his knowledge was positive, and that there could be no mistake about the matter. herefore, must be merely local.

Cuitp GrowTH. —It is a matter of almost daily notice that the children about us are changing, growing, yet of the laws gov- erning this growth, we think but little, if, indeed, we give them any thought. If the body develops normally it receives but little attention and no study from mothers. To the mind we give more heed, although even that receives but a small amount of care until the child has advanced far on the pathway of knowledge. There are laws governing the growth of body and mind which go hand-in-hand, and which should be known to, and studied by, every custodian of children, be it as parent, teacher or guardian. No need to leave our homes, families or schools to study these laws, for right there is the veiled Isis whose study will lead us to igher planes, where, if we would work with half the zeal dis- played in the merely ornamental, we could make contributions of true -value to anthropology, as well as secure to ourselves and children knowledge of priceless value. This mine of wealth is our children, the beloved of our hearts, the treasures of our lives. It is the systematic study of their growth, physical and mental, that I hope we may undertake together.

Children with suicidal tendencies entirely prenatal, others with thievish propensities given and upright parents with noble souls and lofty aims. If we had a record of ourselves, thereby affording us a knowledge of our hereditary tendencies, could we not more intelligently meet, or perhaps anticipate, the needs of our children, more readily coun- teract evil propensities and recognize the good ? We do not realize the value of this work, nor yet the great ad- vantages we have to collect data. Scientists have worked hard, under most trying circumstances, to create an interest in this kind of work as well as to collect data for statistics. Francis Galton, known the world over as a leading anthropologist, prepared a set of cards and hired men to go about England paying people a small sum for each child they would allow them to weigh, measure, take age, color of hair, eyes, etc., that he might get statistics for race characteristics. Fröbel (that mind which saw the needs of childhood and has been such a blessed help to mothers and children) advised mothers to keep a record of the growth of their children. i This record is not a difficult task, and can be best kept in the quiet of home life. It consists of gathering and recording the little daily incidents, surroundings, tendencies, games, pleasures, sorrows and sicknesses of ourselves and children ; also the height, weight, color of hair and eyes, strength of sight, hearing, also oF semblances.

The serrz or dentations are quite abundant for the greater part of the suture, and are particularly frequent in the upper portion. The coronal suture in the vicinity of the anterior fontanelle remains unclosed, permitting a slight movement of the frontal bone. On the sagittal suture, at its junction with the coronal suture (near the position of the anterior fontanelle), occurs a wormian bone of quadrilateral form, .65 of an inch long, by .2 of an inch wide. Back of this the entire sagittal suture is completely closed and obliterated, with the exception of a slight indication of its existence for about one-quarter of an inch at its junction with the lambdoid suture ; a shallow wavering depression along the rest of its former course being all that remains to mark its position. In the lambdoid suture, which is deeply indented, five wormian ones are present. With the exception of one of them, which is triangular in shape, situated at the summit of the occipital bone, by .3 of an inch. The former presents the curious feature of two or more wormian bones within a wormian bone. Usually wormian bones are of triangular form, which gives them the name by which they are also called, viz: Ossa triquetra, or, triangu- laria. In the wormian bone on the sagittal suture, the long diameter is with the general direction of the suture; but those bones in the lambdoid suture have the long diameter at right angles to the direction of the suture. ough the skull is small, it is heavy for its size; and the structure of the bones is solid, massive and unyielding. This is the more worthy of remark from certain indications which would seem to point to defective or abortive ossification. The occlusion and obliteration of the sagittal suture would appear to have found ve ossification, the membranous intervals left in the pro- oT of gs being filled in by these supernumerary bones, de- 1l rance is a decidedly pronounced feature.

Between the extremes of forty and ninety degrees, temperature might be ignored, while wind, sun and rain were to be housed against; so that a high ceiling and a large room with a good roof, the whole being made of rough boards and shingles, was all that even lavish expendi- = _ ture need provide. Glass was a useless luxury; windows were — needed in plenty, however, and full half of the entire side walls. — devoted to them.

[September, vines and tough sinuous growths abounded, and although not lofty were nevertheless hard to penetrate. Small prairies of a few acres in extent were common, and ponds and saw-grass marshes were met with frequently. In the wet season the whole country was under water. In the dry, tide-water only was to be found. Of the wild animals native to these precincts, opossum | and raccoon were everywhere; wild cats of powerful physique, | magnified specimens of the domestic cat, although very rare, lived in the tangles and often wandered to the coast. Foxes of such exceeding beauty of shape and grace of motion that it seemed a crime to injure them, were met with at intervals, and bears, as fat as butter and as lazy as they had a right to be, in diminishing numbers, lived in the great hummocks.

It was a female, and was more than a match for any dog she ever met. Her assault was sudden; the back of the in- truder was reached at a single leap, and its eyes made the object- ive of attack. Instantaneous panic ensued, and when the retreat became assured, she as quickly sprang into the bushes and in- i stantly hid from sight. The dog, relieved of its foe and regaining its confidence, would often return, brim full of fury, to wreak vengeance, when it would be met as suddenly as before, with augmented intensity. Nothing but precipitate, howling flight seemed to suit the requirements of the case, and victorious puss would return with the most comically satisfied and important air. During her boating experience she learned to fish quite expertly. She would spring on her prey when it was near the surface of the water with unerring aim. She did not present an elegant appearance on reaching the shore or boat after a complete wetting, but she always brought out the fish, having no antipathy to the water and swimming like a duck. Alligators abounded in the creeks which I often navigated, and to puss they were per- plexing objects. She strongly objected to their presence, but was undecided how to prevent it. I more than suspected that they would be her fate, as the scaly covering of the saurian would Prevent her claws from securing a hold wherever placed, and should the jaws of the reptile once close upon her, her career would end at once. But I had underrated her resources. A rather small Specimen came familiarly near our camp, and puss — Promenaded a log by the side of which the creature was slowly — moving.

When we were at length housed the kitten had fully matured, = and the ancestral experiences registered in its nervous apparatus were supplemented, or at least confirmed, by many of its own. It took possession at once, explored every nook and corner, routed the mice, and proceeded to enjoy life. rs One morning as I was digging a post-hole inthe sand, a large snake made its appearance near by in the bushes. It remained through the day in sight, and seemed to be greatly interested in what was going on. The next day it was on hand and remained as before. It became more and more familiar, would approach to __ within a few feet of my person, examine each hole as it was dug, r and interview the spade, stuck upright into the sand, by putting its head through the hand-hole and coiling and uncoiling about the handle. It seemed to invite companionship, and to regard me with intense curiosity as a unique specimen for investigation. It was non-venomous evidently, a Watrix torquata or coluber proba- bly, but a native said, “hits a coachwip,” and “coachwhip” it was from that time. It finally became a tenant-at-will, had the freedom of the house and grounds, and was an object of never- ceasing interest. Its curiosity was simply unbounded, and -any = hour of the day or night it was on hand to assist in whatever ; enterprise was in progress. When its acquaintance was first made — I was interested in what puss would think of the new-comer. A contest was expected, but to my complete surprise neither snake ‘nor cat took the least notice of each other. The cat was, how- ever, mistress of the situation, for when coachwhip came too neat was boxed away, gently at first, with more and more claw in each succeeding tap until it obeyed. If the snake was hurt it at least simulated anger very closely, making sham onsets, gather- : itself up as if to dart suddenly on its foe, quivering its head oscillating to and fro in a forbidding manner. It was really inches in diameter in the thickest part, and when in Soe seemed formidable ; but puss paid no attention to the fuss, shat- ing her eyes and sleeping in the midst of it all. w k in the still- ht and see the coluber’s bright eyes, a foot above 886.] ee Animal Traits. | 761 the table, peering at the luminous shade, upon which, by the way a juggler and his snake were pictured. Late one afternoon I answered bob-white’s whistle by slipping cartridges of fine shot into the chambers of the gun, and pro- ceeded to the clearing. There was found a large wild cat in pos- Session, quietly sitting on its haunches on a sweet-potato hill. The longitudinal stripessand grim markings behind the ears were unmistakable, but no bars on the tail. It seemed a friendly beast, devoid of that look of wild ferocity characteristic of its tribe in more northern places, nevertheless had I been unarmed a foot- race would have been in order, but knowing that the unexpected might at any time happen, I never went about without some weapon of defense, and had entire confidence in small shot at h close quarters. It made no motion of retreat as I advanced, but w slowly opened its jaws and crouched as if gathering itself fora spring. Not desiring to injure it I backed away, only to be fol lowed. This was not endurable, and having no wish to give it a = the least advantage, I killed it. e The next thing was to see what opinion the domestic cat would have of this distant relative, for I could not entertain the notion _ that they were cousins germane within the historic period, so arranging the carcass to appear as lifelike as possible, I induced Puss to follow me to interview her dead congener. Alas! cat- : glory resembles human glory, and is liable to vanish at any time. Puss got within a few feet of the body before she saw it, and just as I was expecting to hear her inquiring “ mew,” there came in- - ‘Stead a transformation which was indeed surprising.

She was badly scared, her fear had no paralyzing function, 762. , ` Animal Traits. : [September, without the least trepidation, examined it critically, crawled over it in all directions, and went through its habitual pantomime for all unfamiliar things. At times fish and wild game was provided in superabundance, and as the refuse went out of the window near the dining table, a depot of supplies for the animals of the immediate neighborhood was established. The scolding of opossums and raccoons was noticed, and at intervals the sharp bark of a fox was heard in the night hours, while every scrap of eatable stuff disappeared. Puss had often perched herself on the window-sill while this devouring of garbage was in progress, but seemed indifferent to what was going on. My approach, however guarded, occasioned the retreat of the animals, so that I could get no more than a glimpse of them. Remembering the dazzling effect of light at night on deer, I lowered the reservoir and burner of the lamp to the base, and holding it by the ring above, advanced to the window with entire success. Putting the lamp on the outside and leaning against the sill, a full view of the animals was had not more than six feet away. They seemed to think all was not right at first, but soon resumed their feeding and quarreling unconcerned, A brood of opossums, a couple of raccoons and a fox were on hand. The latter continued Suspicious, gazing into my eyes for several Seconds, but seemed convinced that there was no danger after the _ examination. So long as all movement was behind the light, _ everything was serene, but if the hand or a stick were advanced an front, panic at once seized the crowd. But where were the foxes’ ‘senses of smell and hearing? Were the olfactory and audi- tory nerves demoralized, as the optic seemed to be, by the ethe- real vibrations from the incandescent body? One would think that at six feet distance at least the fox could smell its enemy 1” spite of the light. This kind of lamp-light scrutiny was of never failing interest. The animals were fresh from the hand of nature anc on their native heath.

Reynard always respected this show of ivory, as the raccoons did also. But in spite of all the precautions taken by the mothers, a strict count of children after home. was reached would show loss. When they were shaken off one would be a little late in regaining a position of safety, and in the hurry consequent on the fox’s arrival, this tardy scrambler would prove to be the one not fitted to survive. It left no legacy to its descendants for it never had any. The celerity with which it was _ Snapped up and carried off was commendable; a single squeak ___ Preluding a mingling of protoplasms. ; This kind of observation went on through the rainy season to the following November, when the waters began to subside. The young opossums had escaped from maternal care and were their own masters, when one night a stranger arrived. The feeding company consisted of a huge opossum, several raccoons and a fox, when another wild cat, younger and smaller than the one killed, dropped from above into the center of the feeding ground, now worn quite bare. The fox sprang from the earth, barking with every jump, as it tore through the bushes in its frantic efforts to escape. The, raccoons could be heard butting against the sleepers of the house in their lumbering flight, while poor puss went like a meteor through the opposite window, making a total _ Wreck of the dining dishes, and did not appear at the house for : Several days. Opossum did not run; rearing backwards toan _ Upright position, with wide-open mouth and such a disposition of — its feet that its body seemed all claws, it held its ground with a — snarling protest of intense anger. “The undaunted fiend what ~ T this might be, admired.” Opossum presented no vulnerable _ Point but down its throat, and it was unwise to assult in that _ direction. The cat got upon its feet and walked around raising "S paw, but seeing no good place to strike. In fact no good place existed. The defense was vertical, and the assault made _ "om a horizontal plane was alike bad from all directions. The east in Manceuvering for an attack got his tail within reach of iy left hand, the right being engaged with the lamp; the tempta- On to seize it was irresistible. Calling out “ puss I have you,” aS a firm hold was obtained, instantaneous panic ensued, and the fox’s method and line of flight was closely followed. Had my asp been as vigorous as that of Tam O’Shanter’s witches, wild “at would have been transformed into lynx then and there. e Animal Traits. [September, Coachwhip was an interested spectator of the whole affair, and - when it was over and the relieved opossum had shut its mouth, I = thought the snake had gone insane. It tore around the room . like lightning, tied itself into innumerable knots, wove in and out of the chair rounds, made sham charges, and ended by rushing out of the door and taking to the bushes. = Poor coachwhip met witha sad fate at last. One quiet day it had discovered a mouse in the yard hidden beside a billet of wood = ina position so insecure that it took to the grass, and the snake lifted its head a couple of feet high to get a view of the escaping prey. A rush of wings and mingling of shadows took place, and Natrix went aloft in the talons of the king of birds, No time was to be lost. Shot was wanted, but only bullets were available. I emptied the full chamber of a Winchester rifle at the pirate, but every shot missed. The bird made directly for its nest that I knew of two miles away, but when the tree was reached, coach- whip had departed this life, and had no less than three living — tombs. It is evident that the great doctrine of the conservation and correlation of forces, as applied by evolution, has thrown a new- and brilliant light upon these animal traits. They are no longer isolated facts, having their ultimate explanation in the specific characteristics of the creature, but legacies from ancestries reach- 3 ing through the geological epochs to the earliest fossiliferous £ rocks.

Well, “instinct is a great matter,” and would serve for the age of William Paley, who knew nothing about the conservation of forces, but science has, added a new world to our possessions since then. Think of it a moment. The ethereal undulations flowing from the surface of the snake, opossum and raccoon which enter the — eyes of the cat and disturb its optic nerves, assisted, it is reason- able to suppose, by odors emanating from their bodies disturbing __ its olfactories, cause mild muscular action or none at all, while 22 the slightly different modes of motion from a wild cat’s body set y up activities so intense as to suspend the action of other faculties and concentrate the whole force of the animal in changing the space relations between itself and its enemy. So violent is the | disturbance that the sensation of hunger is suspended and several days are passed without food. Friends are no longer recognized. _ Everything manifesting motion is held a foe. A position as far away from the dreadful apparition as it was possible to find was held for three days, in a constrained attitude against the roof at — the gable, with eyes phosphorescent at night and much dilated, — and the unnatural tension was not for a moment relaxed at any time that she was observed. . Se We are driven to the conclusion that long ages had passed- during which the ancestry respectively of the wild cat and the _ domestic cat were enemies, and that when collision occurred the _ domestic line went to the wall. During this time the present Markings of the wild cat and its odor were acquired, pointing _“nmistakably to a long period of separation into species as di: “nct as we now find them to be. For it is very certain that puss never before saw a wild cat, nor is it very likely that her parents ever €y are extremely rare in Florida, and nothing but lon frequent contact could arrange so vast a force about an equi num so delicate as to be overthrown by a mere arrangement of very ordinary reflections of light and trifling molecular dis- po Of an odoriferous character. 2 op n : Sele oe Animal Traits, [September, _ _A further matter forced itself upon my attention.

MATTHEWS, U.S.A. aie plant-lore of the Navajo Indians compared with that of white men who are not specially versed in botany, is remarkable for its extent and accuracy. There are few species of phenogamous plants, among the varied flora of their country, for which they have not distinct, well-chosen names, and of whose physical properties they have not made some observation. True all do not possess such knowledge, and one is sometimes in dan- ger of being deceived by the uninformed who will coin a name for the occasion rather than confess ignorance. This knowledge is, however, pretty well diffused, and there are many grades. of Proficiency in it. The better informed, in widely distant parts of the Navajo country, agree closely as to the names and properties (of the great majority of species. My best informant was an old woman, probably over seventy years old. My next best in- formant was a very intelligent man of about thirty-five years of- age. An old priest or so-called medicine-man, over sixty, who knew the Shamanistic rites and the elaborate mythology of the tribe perfectly, knew less of plant-lore than many others. It Would seem that it is not the oft-quoted wise old medicine-man — of the Indian tribe who knows the most of nature. I have heard _ from many Navajos of a wise man dwelling in the far north-west- — rn part of the Navajo country who knew most about the vege- table kingdom of all the Navajos. I regret that I never hadan — °pportunity of meeting this man. He seems to be their highest _ authority in botany. z Not only do the Navajos discriminate all the more important Species, but they are not devoid of generalization among allied Species. In some cases this generalization agrees with our own. For instance, there are three species of juniper growing in the Zuni Mountains; each has its own appropriate name, yet the generic name for juniper (oth) appears in all. The most common kind of sunflower bears the name of indigili; as with ourselves, this eak čen as a type or foundation species of plants in the sub- _ tribe Heliantheæ, and we have indigilt nilchini, strong-scented 4 Sunflower (Verbesina enceloides), and indigili nilchinitso, great A j ‘Strong-scented sunflower (Helianthus.nuttallii). os Of a class of plants so rank and showy as the sunflower [September, family, it is easy to credit this; but it is more difficult to realize that in the obscurely flowered and unattractive Chenopodiacee and Amaranthacez their faculties of observation have guided them as safely. In the section of the Navajo country where I did most of my collecting there are two species of Chenopodium so— _ much alike that white people in general do not distinguish them from one another but call them all “lamb’s quarter.” Thereis still another so little like its congeners in its macroscopic charac- ters that none, I imagine, but the scientific could trace the _ relationship; this is the Chenopodium, or Teloxys cornutum ; when _ burned it emits a fine aromatic odor, and in the late autumn it changes toa rich rose-lake color which lends a beautiful tint to _ the slopes of the Zuñi mountains. Again the relationship be- tween the goosefoot and amaranth families is not known to the unscientific among ourselves. That the Navajos have traced some character in common, in these instances, is evident from the following names : Chenopodium Sremontii, tlotahi. _ Chenopodium album, tiotéhi-tso, or “ great tlotaht.” Teloxys cornutum, tsinya tlotahi, or “ tlotahi under the trees,” from its sub-arboreal habitat. $ _Amaranthus retrofiexus, tlotahi-hochi, or “ a tlotahi.” _ They do not however apply the name “ofd/i to all the Cheno- aceæ, but they evidently connect the not very similar genera of Atriplex and Sarcobatus, the former being called togoji, refer- ng to its spines, and the latter éogosijin, or “ black toggyi.” hey are not» always thus happy with their classification, for lacinata and Castilleia affinis, representing the widely sep- — 1 families Caryophillacee and Scrophulariacee are : tahitihita, “ humming-birds’ corn,” because humming-birds _ often seen hovering over them. The Indians do not suppose L to be the same plant, but will tell you they are different though named alike.

I once took some of _ this Comandra to the man whom I have described as my second- best informant, yet doubting whether he knew anything of such a rare and, to me, useless plant. Without taking it into his hand or honoring it with more than a glance, he named it. I expressed some doubts. He replied, “I know it well. It has a blue root.” Feeling now positive he was mistaken, I exhibited the root, which was a distinct white. Without answering he took the specimen — _ out of my hand, scraped the root with his thumb nail, handed it back to me and told me to observe it fora moment. To my sur- — prise the denuded root changed from white to a delicate cerulean tint. as sA — È! — On another occasion I met the same Indian carrying, in the e fold of his blanket, some specimens of Pectis angustifolia, a plant which on the dry mesas of New Mexico does not attain a height ~ Bo of more than two or three inches, but it has a delightful odor, — ‘> like that of lemon verbena, and its infusion is used by the Nava- a josasa carminative. Their attention has therefore been drawn _ to it. The name given for the plant was so peculiar, signifying “a — = 2 breeze blowing through a rock,” éseganilchee, that I made no delay ~ in getting an explanation from him. He-led me to the top of a — _ desert mesa where the plant grew fresh. Here he picked up a ~ Piece of sandstone about a foot square and three inches thick, and _ held it up to yes saying, “ Do you smell anything on = a to my nostrils. The agreeable odor was at once distinctly Perceptible through the rock. Some minutes later it could be detected in all parts of the fragment ; but at first it was perceived at a point directly opposite to the point of application. Later he betlormed the experiment on a large stone nearly two feet thick; the results were the same as with the smaller stone, but more €, hence the name.

BY SAMUEL N. RHOADS. (Continued from p. 701, August Number.) THE nearest roost to Bristol, now existing in the State of Penn- Sylvania, of which I am able to get account, is situate in ontgomery county, on the farm of Alfred Moore, and near the ` Post-hamlet of Davis’ Grove. This gentleman informs me that they (the crows) first came to his place in the winter of 1878, rom Camp Hill, in the same county, which locality he remem- F to have been their rendezvous for twenty-five years. The Present roost covers about twenty acres. Careful average esti- roia of the number of birds commonly roosting per acre show _ “© Maximum to be about ten thousand. Therefore, although 778 Crow Roosts and Roosting Crows. (September, my correspondent playfully hints of there being “ millions in it,” we may more safely place the number of crows resorting to his farm at night within two hundred thousand. Were we to accept as proven that the so-called Bristol roost, of which Godman speaks in 1830 as having contained a million crows, was situate on the west bank of the Delaware, it might be fair to assume that these two hundred thousand represent, at the present day, that mighty host of ancestors. However welcome such intelligence would be to many crow haters, it would be un- fair to infer that the proportion of crows living at present to the number living fifty years ago is as one to five. The experience of older residents of the country justifies the belief that great diminution has been made among the myriads and probably a census would show that the crow population of to-day is to that of 1830 as one to two. When we take a broad © view of this, it is easy to predict that, despite the increasing pai ning and wariness of the nineteenth century crow, he must either totally renounce his partiality for the haunts of men, or speedily become extinct. As this trait seems inextinguishable in the bird, mankind should seriously determine the economic relations of crows to men ere too late. This is fully worthy the impartial inves- tigations of the American Ornithologists’ Union, and we may well rejoice to see that the cause of an unjustly persecuted bird 18:0 longer left to the tender mercies of interested farmers, indiscrim!- nate gunners, and uninformed legislators. In investigating this subject, I am led to think that very large roosts are nowadays less popular than formerly, or, in other words, that roosts have increased in numbers as the crows have diminished. ; By sad experience they have found that unlimited union F weakness rather than strength,and have divided into smaller an more numerous companies, each having its favorite and giare? locality, to which every member shows inviolate attachmen during winter. . I am unable to discover that any roost exists in Pennsylvania, other than the one just mentioned, on the farm of Alfred Moore. = This is inexplicable, as the conditions of this place no De answer the requirements of a roosting crow than EE _ other places in the neighboring counties. It goes to prove Re a crow must inherit an attachment to localities even unto the fas : : ‘generation, nay, even unto death. 1886.] Crow Roosts and Roosting Crows. 779 What bird more justly merits the blessing of long life, if we reward him according to his way of honoring father and mother by cleaving to the unaccountable eccentricities which seem so out of the common order of corvine habits and customs ? In this respect the Pea Patch and Reedy island roosts are parallel instances. Though my personal experience is confined to the roosts of New Jersey, outside information supports the conclusion that more crows pass the winter nights in that State than in all the rest of the Union taken together, and a few months careful ex- amination has ‘shown that in the counties of Camden and Bur- lington nearly every tract, ten miles square, contains one of their dormitories ; also, that in the western half of Burlington county, which would include four such tracts, there are at least seven localities known to the writer as being the resort of from one to three hundred thousand crows nightly. A more thorough canvass of the subject would undoubtedly reveal three or four more such places yet unheard of with accu- racy sufficient to justify a present enumeration in the roosts of Burlington county. A list of those roosts which have come un- der notice will be given at the end of this paper. Roosting places, in proportion to their immunity from invasion, are used year after year, and probably before the settlement of our middle dis- tricts many of them were centuries old. That one in Maryland of which Godman speaks as being so ancient that the droppings had accumulated to the depth of several feet, and the fermenta- tion of which he supposed sufficient to contribute to the warmth of the roost, is unparalleled by the crow dormitories of to-day. It seems hardly credible that such a store of guano should have long existed among Southern agriculturists, nor can we believe that the native pines of Maryland, indigenous to a thin, infertile Soil, could have borne such high-grade fertilizing. For the sake of consistency we may cut down “feet” to inches in order to Save the trees, nor do we think it either possible or necessary that a crow warm his bed-chamber in such a manner as our Worthy author suggests. So universal has been the persecution of these birds at night, We will not be able to find among the many roosts now in use More than half of them of ten years’ standing. This necessity for quitting old-established resorts has taught the wary birds a les- 780 Crow Roosts and Roosting Crows. (September, son, for in their struggle for self-preservation they have re- nounced the sheltered retreats of pine forests and when forced to seek another refuge invariably select higher ground and decidu- ous woods, preferring to perch on the topmost twigs of bare and leafless branches, and brave thus the rigors of a winter's night than court destruction among the dense pines, whose darkling shade conceals the movements of their arch enemy. The partial migration of crows to the vicinity of Philadelphia from North and West leaves a few individuals to winter in New England and some of the Western States, but their numbers are, comparatively speaking, so insignificant that their roosting places have not been noticed by ordinary observers. I received word from William Brewster, of Cambridge, that, while he has no personal knowl- edge of roosts in New England, “a taxidermist in Brookline (near Boston) told (him) years ago that there was a roost somewhere near his house to which several hundred resorted every night through the winter.” ; A foot-note in Wilson’s account of Corvus americanus refers in- cidentally to a similar place in New York State. It reads thus: “A few years ago,” says an obliging correspondent, “I resided on the banks of the Hudson, about seven miles from the City of New York. Not far from the place of my residence was a pretty thick wood or swamp, in which great numbers of crows who used to cross the river from the opposite shore were accustomed to roost.” Of Maryland we have already heard through Dr. Godman. H. W. Henshaw has kindly furnished me with valuable additional information respecting a roost near Washington, D. C., “between the Aqueduct bridge, just above Georgetown, and the Chain bridge, some three miles from the latter.” In the “high, deciduous trees of Arlington cemetery” is g7 other favorite resort, and the same gentleman adds that one P? these roosts includes about eight to ten acres of woodland, chiefly composed of deciduous trees. We may conclude that, since Godman’s day, Maryland crows have forsaken the pines of the esapeake region, and, like their New Jersey brethren, € a more stormy perch among the bare branches of deciduows _ forests. My informant estimates the number of crows winter fe about Washington at near forty thousand, stating that, ‘ine opinion of many, the number is much greater, and I think I have _ Seen statements in the newspapers running up into the hun 1886,] Crow Roosts and Roosting Crows. 781 of thousands.” The Washington crows derive most of their food from the immediate vicinity of the Potomac, either on shore or from the numerous flats and bars within the river, both north and south of the Capital as well as from the eastern branch as far up as Bladensburg. Thus is formed two distinct morning flights from Arlington, the one going southward beyond Alexandria, and the other, which attracts most notice from Washingtonians, passing over the city toward the east branch. This roost has been known to my correspondent since his resi- dence in the District of Columbia (fourteen years), but in his opinion the crows must have made many changes in their choice ofa resting place during the late war on account of the wholesale destruction of timber in that vicinity, and former roosting places were probably abandoned on all sides during the period of de- vastation, That similar places to those already mentioned exist shore- wise in the States of Maryland and Virginia is not yet proven, but we may feel assured from our knowledge of the abundance of both Species of crow in these parts, that inquiry will reveal their existence. From what we know with certainty, facts tend to show that as we go northward, southward or westward of our City of Brotherly Love in the winter season, the number of crows tapidly diminishes. The Washington roost differs from those located further north, in the fact that the fish-crow, Corvus ossi- Sragus, resorts thither in common with C. americanus. The pro- Portion of fish-crows to the latter is as one to five, and although the species do not at other times consort together, there appears to be no attempt on the part of either kind to keep aloof from the &eneral movements of the body-gregarious during the nightly Gathering, but the admixture of the two species is uniform throughout the flock and harmony is a law recognized by them as it is among the several species of communistic black-birds. _ My friend’s experience herein differs decidedly from that of both Audubon and Wilson. _ The words of the former naturalist have been already quoted," and Wilson in his account of the fish-crow mentions particularly that they retire to high, interior forests, whereas the commoner Species generally roosted along water-courses among the reeds. _ *See p. 693, August number. ~ _ seem to have a definite object—either for toilet or gastrono 782 Crow Roosts and Roosting Crows. (September, Shall we infer from this that the relations existing between our two eastern crows have so materially altered in the last eighty years, or shall we consider that the two great pioneers of Amer- ican ornithology were not well informed ? Possibly the “misery” of nineteenth-century -crows “loves company,” which eighteenth-century crows were too aristocratic to keep. With rare exceptions, such places as are referred to by the afore-mentioned authors as the usual roosts of Corvus americanus in former times are nowadays unfrequented. Is it possible that the extensive roosts of Central New Jersey were not so used a hundred years ago? At present the majority of roosting crows do fly far into the interior to pass the night, though it cannot be denied that preference is nearly always shown to the vicinity of some water-course. It is possible that neither Audubon or Wilson had knowledge from personal observation of any roosting place of C. americanus far enough south to include the winter range of C. ossifragus. A visit to one of the numerous roosts of New Jersey would repay any one interested in nature and reward the curiosity of the most casual observer. The course adopted in assembling to and departing from the chosen spot is uniform everywhere. About an hour before sun- set stragglers begin to appear, reconnoitering as it were to see that the coast is clear, and returning whence they came as if to inform the main body of the result. In the course of half an hour the flocks begin to arrive in broken lines and detachments from all quarters, and, if the evening be calm, their earthward descent from a height of many hundred feet exhibits aérial poe surpassing in daring elegance those of any other land bird with which I am acquainted. It is their invariable custom to descend to some spot in = neighborhood from one-half to a quarter mile from the roost, preliminary to assembling there for the night’s repose. This may be either upon the adjoining fields or on woodland tracts near by. Such preliminary gatherings, as Godman eerie purposes—a time, also, if we may judge by their clamọf, : = general conversation, some rejoicing, some repining 17 ee ~ Varied experience of the last twelve hours.

To descend almost perpen- dicularly from a height one thousand feet above earth to the very tree-tops and then to glide above them on half-closed wings with a resultant momentum that is almost startling in its arrowy ve- locity, is a favorite manceuver, and when two such playfellows pursue each other in this headlong swoop their turnings and twistings and doubling contortions amaze the beholder. It reminds one of lightning in feathers, but the results are surpris- ingly harmless, and it may better be compared toa shower of day meteors whose “ radiant point” lies somewhere in East Pennsyl- Vania, Until sunset this novel scene continues without interrup- tion, whilst field and forest in the vicinity of their great dormitorie are shrouded by the thousands which have alighted, and, were it not for their deafening clamor, the living pall which overspreads the scene might well suggest a land of mourning and death. When they settle on the ground on such occasions they resemble gulls on a sand-bar, each standing motionless with its head toward the breeze. The whole thing seems unnecessary, as they mostly do nothing but cry out to their companions in the air and tumultuously applaud their hair-breadth escapes and feats of daring, yet sitting quietly until the setting sun warns them to make ready for the last act—“ going to bed.” Tf we understood crow language perhaps we could now recog- nize a distinct signal from some grand master of their assembly, summoning all to repose. Be this as it may, a sudden impulse now seizes the throng and the air fairly darkens as successive Companies take wing and in silence betake themselves to the roost, flying low as if to avoid observation. Many crows in ap- Proaching the places of preliminary gathering necessarily fly over roost, but not a bird enters it until the general movement begun after sunset. The self-imposed discipline and obedience of such an army puts to shame the strictest military code. Think neve of a miserable, weary crow which, having winged his way thither a distance of twenty miles, arrives about sunset at the toost; but, the ingathering not having yet begun, witness how = €a true soldier he flaps on to join his more punctual brethren 784 Crow Roosts and Roosting Crows. (September, who have settled half a mile further off to gossip and plume themselves before retiring. On one occasion I observed large companies arriving in the roost near Merchantville, at a time of full moon, for nearly an hour after sunset. Between the intervals of arrival all would be- come quiet in their bed-chambers, but, as a more belated com- pany drew near, their cries were responded to by the roosting crows in a different tone. The fliers would hurriedly ejaculate yur, yur, yur, as a Southerner pronounces “here,” giving each utterancea rising inflectionas if inquiring anxiously of their where- abouts, while those in the roost answered in a falling, drawling tone by slowly repeating their usual “caw” and lengthening it to ca-aw, ca-aw, ca-aw, as if to assure their friends they were resting comfortably, Above all places I ever visited, these roosts afforded the best opportunity for study of bird language, and furnished enough suggestions to threaten mental dyspepsia. The monosyllabic speech of a crow is by most accounted to be little more than a monoverbic “ caw,” but let such as thus re- gard it visit a crow roost and attempt to classify the sounds there produced and, if his ear be well set to music, he’ll have a long list. Among birds so eminently gregarious, language naturally be- comes an ever-abiding necessity. A crow is as great a conversationalist as is the nightingale a great singer; this one, out of the heart’s abundance, voices his music from a pure love of harmony; that one, out of the abundance of his wisdom, speaketh ; this is the sapphic humming of a tune; the other, a terse, laconic sentence made up of one word, yet calculated by its variety of modulation or of emphasis to convey variety of idea. On every occasion of my visits to those places the strange sounds uttered by those crows already gathered in the dormitory were a continual surprise. Were it possible to reproduce such sounds before a body of ornitholo- gists, nine-tenths of them would have no thought of assigning them to the vocabulary of any North American bird. Fifteen years’ intimate acquaintance with C. americanus (prior _ to visiting a roost) led me to regard him as the most monotonous _ of linguists, but a more extended experience reveals that he en- | _ joys an after-supper discussion with the family as much as ae _ do.

At intervals of half a minute, a certain crow usually relieves the monotony of cawing by making a melodious sound which is inimitable and somewhat resembles the noise made by a porter bottle when skimming swiftly over an expanse of ice. It has no kinship to cawing, but a semblance to the hollow love-notes of Scops asio, shortened into an utterance of two syl- lables, Tam persuaded that not one of a thousand crows is able or privileged to utter this sound, having often listened in their very midst for an hour without hearing more than three individuals making such. This either implies that one crow differeth from another crow in natural accomplishments, or that there is a recognition of chief speakership among them. Possibly it means oth. Another sound is the invariable accompaniment of “ going to bed,” and judging by its frequence it is not restricted to the few. This, according to a note taken on the spot, is “ a strange noise as of a person choking or being strangled to death, or like Sound of chicken when caught” and suspended by its neck. This terribly suggestive note is alone sufficient to keep timid and Superstitious people away from such haunts. In early-morning conversations on the roost we can hear the Sreatest variety of notes. One of the most notable of these re- sembles laughing in its hilarity of tone, and sounds something like garrick or cla-a-a-a-arick by trilling the a’s and r’s at a high, feminine pitch of voice. It has kinship to the familiar ejaculation ofa strawberry woman in the city street. Another utterance consists in prolonged clucking as of a hen: clăüŭüŭück, or clu-ŭh-ŭh-ŭh-ŭh-ŭh-ck, or, as my field notes have it, “it sounds like a hen trying to gargle.” Individual peculiarities of voice arising perhaps from derangement of the vocal organs are often amusing. I may not soon forget that of a crow in the Merchantville roost ch ceased not to cry at intervals of half a minute, “ oh wait, oh wait,” in a piteous tone, laying peculiar emphasis on “ wait,” as if upbraiding its companions for leaving it, which they were actually doing at the time. Whilst lying on the ground observing the actions of this noisy Multitude I began “ cawing ” after the usual fashion of the birds 786 Crow Roosts and Roosting Crows. (September, above me, reproducing, as I thought, their call-note with sufficient exactness. Had I discharged my gun their consternation could not have been greater, for in an instant there was a hush, followed by a sudden uprising of thousands occupying the perches nearest to me, and then for a minute the uproar was tremendous, every tongue seemed upbraiding. When order was restored I climbed a tree, and on reaching the ordinary roosting level, repeated the experiment. Herel found a man’s voice had no terrors, and so long as I “cawed” they took no notice of me. of surprise or joy or alarm. These observations on the roosting language of crows may receive considerable and interesting addition from a critical study of the bird during the spring and summer seasons, for in the bei clusion of the family circle his converse differs widely from t n described. y way of conclusion I may further add that the programme of dispersion from the roost in the morning to their feeding grounds is as follows : i After an hour’s babel (for such verily is the seeming conha of tongues) a few crows essay to take leave, but as soon as x r folly is observed it literally “ brings down the house, and w = one imagines the simultaneous shout of twenty acres of crows, one may not wonder that “ the house” is fully able to bring dows the crows.

JAPANESE HOMES AND THEIR SURROUNDINGS.—It has long been strenuously maintained by the NATURALIST that human arts can and should be subjected to the same methods as genera and spe- cies in natural history. The questions of structure and function, evolution, ontogeny, distribution in time and space, relations as affected by and affecting contiguous phenomena may all be put to the products, appliances and methods of human activity. Whenever a student of any department of man’s works has caught the spirit of this plan of investigation, we have hailed his work as a lasting contribution to the noblest of sciences. - Professor Morse went to Japan as a trained naturalist ; his work on the shell-heaps of New England prepared him for his greater work on the shell-heaps of Japan. This accomplished, the most natural sequel was a close study of the modern successors of the primeval race whose sole record remains in their refuse piles. Omitting food, clothing, all other industrial pursuits, the professor gives us in his charming volume an insight into Japanese homes. It were mildly putting the matter to say that the author is in love with his subject, indeed it here and there takes the bit and runs clean away with him. Most people like to read that kind of a work, however, forgiving all eccentricities born of genuine enthusiasm.

As all rooms are made in sizes corresponding to the number of mats they are to contain, the beams, uprights, rafters, floor-boards, ceiling-boards are got out in sizes to fit. From one end of the empire to the othera mat is approximately six feet long and three feet wide. The ceilings of the Japanese rooms are low, and everywhere appear posts, supports, cross-ties, etc., exposed and decorated in exquisite taste. The most noteworthy feature of the chief apart- ment is a kind of bay divided into two parts, the tokonoma and chigai-dana. The bay nearest the verandah is called the zokonoma, in which hang one or two pictures, and on its slightly elevated floor stands a vase or some other ornament. The chigai-dana its ceiling, all closed by sliding screens. In the development of these two architectural features Professor Morse dwells at length and with much eloquence upon the advantage of the free-hand architecture of the Japanése over the bilateral symmetry carried to excess in house interiors among us. ; The space between the upper end of the screens and the ceil- ing is the ramma, and here Japanese finesse has reveled in panel, diaper, open bamboo work, porcelain and wood-carving. i —— LEE ENES T NY —S —~ a pete a e PA G e o E ROR Sli Fic, 6,—Ramma of bamboo and perforated panel.

GEOGRAPHY AND TRAVELS.! AMERICA.— American News.—Col. F ontana, Governor of Chubut (the northern part of Patagonia), has followed the River Chubut to its sources in the Andes, about 42° S. lat., and has thence crossed prairie and forest to the 46th parallel. He found three passes into Chili, laid down accurately the courses of several rivers, found the source of the Senger (an affluent of the Chubut), verified the positions of Lakes Colne and Musters, and deter- mined the positions of the spots at which the Senger and Chico debouch into the lake. The June issue of the Proceedings of the Royal Geographical Society contains a sketch of the physi- cal geography of Brazil, by James W. Wells, accompanied by a map showing the forest, grass, and arid regions of the country. many interesting details about the present state of the population, railways which, diverging from Sao Paulo, Rio de Janeiro, and other matters. A tolerably full account of the superficies, soil, climate, people, commerce and industries of Venezuela, by M. P. Druyckler, may be found in the Bulletin of the Antwerp Royal Geographical Society, 1886, 5th fascicule. Guatemala had, on January 1st, 1886, a population of 1,322,544, showing an increase of 37,940 over that of the first day of 1885, or nearly three per as per annum. The births in 1885 were 63,687, the deaths 1/47. Asia.—Persia—Mr. J. A. Rees describes, in notes published ast year at Madras, a journey from Kasvin to Plains, covered with corn (grain), vineyards and orchards, while b © alls give a fair return of wheat without irrigation. r. Rees clieves that the population of Persia is much under-estimated. ersian notions about Francistan and Inglestan, the division of arangistan, and of the country of the “ Ooroos” (Russia) are er amusing.

The Turki Tongues——Mr. Morison, of Tiflis, has contributed to the Journal of the Royal Asiatic Society a summary of the dis- tribution of the Turki languages. Turki proper is spoken by the Turks of the Ottoman empire, in the Russian governments of Nijni Novgorod, Kasan, Simbirsk, Viatka and Orenburg; in Trans-Caucasia and in N. W. Persia. The Nogai branch is used in Bessarabia, the Crimea, Cis-Caucasia, the Volga delta, North- east Daghestan, the Terek valley, the N.

W. Siberia; and the Yakut in N. E. Siberia and the northern slopes of Mount Sayan. Thus the Ugro- Altaic tongues extend over 100° of longitude and 35 of latitude, and Turki alone is the language of twenty millions of people. and new-comers, though the Chinese have supposed all to be abo- rigines.

The four commissioners ascended the Ubangi, which seemed to start in the right direction, but found that it turned northward. The Ubangi and Licona-Nbunga are two perfectly distinct streams, instead of forming a common delta, as has been before stated. The Island of Diego Garcié.—Gilbert C. Bourne describes in the June issue of the Proc. Royal Geographical Society the coral atoll of Diego Garcia, belonging to the Chagos group. There are four openings into the lagoon, one of which affords a passage six to eight fathoms deep. The lagoon has an average depth of eleven fathoms, and forms a good harbor. The strip of land varies from about twenty yards to a mile in width, and is densely covered with cocoanut palms, Scevola kenigii and Tournefortia argentea. The interior parts of the main island have a black peaty mould, formed by the decayed leaves of the cocoa-palms. Here grow Guetturda speciosa, or “bois de feu;”’ and Cordia subcordata, or “ bois malgache.” A Casuarina grows on the east side of the island, and Hernandia pelttata and H. ovigera (bois blanc), as well as Pisonia tnermis, also occur. The gaiac (Afzelia byuga) forms a single group in the northeast. The staple pro- duce is cocoanut oil, and the island is in the hands of a company at Mauritius. The only wild animals are introduced rats ; fifteen Species of birds occur, only one a land bird; the Mauritian gecko (P. latydactylus mauritanicus) is common, and there is a mud tortoise at he has seen it do so. It eats the nuts that are on the ground, but ascends the palms for shade and protection.

GEOLOGY AND PALAONTOLOGY. WALCOTT ON THE CAMBRIAN OF Norra AmERIcA.—Mr. Wal- cott has contributed to the August issue of the American 7 nal of Science an able essay upon the Cambrian system. fte regards the Potsdam of New York and the Mississippi valley, with Dicellocephalus, as Upper Cambrian; while the Cambrian of Newfoundland and Braintree, Mass., with Paradoxides, he places dle Cambrian age.

On the Grand cañon of the Colorado the Tonto beds (1000 feet) carry a fauna akin to that of the Upper Cambrian of Nevada, Texas and the Upper Mississippi valley. Beneath the Tonto lies the Grand Cafion series, which Mr. Walcott classes, together with the Keweenaw of Wisconsin and the Llano of Texas, as pre- Cambrian. The Eureka and Highland Range sections in Nevada and the Georgia section in Vermont prove the stratigraphic position of the Middle Cambrian. In Nevada the Middle Cambrian fauna is from 2000 to 4000 feet below the Potsdam, and only three spe- cles pass up into it. In the Georgia (Vt.) section one species Genera. Species.

Discina, Pleurotomaria, Amphion, Bathyu- rus and Ogygia are doubtfully referred to the Cambrian. Several other genera pass up into the base of the Lower Silurian. GEOLOGICAL News,—General._—M. Jelsky (Bull. d. 1. Soc. Geol. de France. 1885, 581,) brings forward concerning the origin of earthquakes and the lifting of mountain chains a theory to some extent new. Postulating a liquid interior and the constant sink- ing of the heaviest portions of the crust, which he believes to be the ocean bottoms, he shows that the sinking cannot be perfectly uniform, since a solid always bears much compression before it yields, and asserts that the sudden sinking must producea plutonic wave on the surface of the liquid interior. Under the conti- nents cavities probably exist, caused by the lifting of the crust by former plutonic waves which, when they sank, left a space be- neath the crust their movement had raised. When an earthquake is produced by sinking of the sea-bottom, it may (1) spread itself. over a vast area if it is propagated to a broad sub-continental cavity ; or (2) it may produce a volcanic eruption; or (3) it may lift a portion of the neighboring continent. e presence of vol- canoes is thus attributed to the pressure of the plutonic wave, an this explains the frequency of volcanoes in non-continental re- gions, or near the sea-margins, where there is no extensive cavity below. The perpetual waste to which a continent is subjected must finally cause its ruin; the vault becoming so thin that it breaks at the shock of a great plutonic wave. The recoil of the wave, aided by the weight of the broken vault, will cause the ele- vation of a portion of the sea-bottom and the formation of a new mountain chain, while the sea, rolling toward the sinking part, aids the change by the transference of its weight. Professors Romanovsky and Moushketoff have issued the first of three vol- umes upon the geology of Turkestan. From this it appears t we nearly the whole of the Aral basin, including the wide tracts, east and south-east of the lake, is covered with chalk; the remaining twentieth being occupied by crystalline unstratified rocks, meta- morphic slates, and Paleozoic deposits, all the hills rising above the steppes being Archzan or Palzozoic. Jurassic deposits a) on the Baidam and Saram rivers, on the borders of the East orn life-remains.

The limits of the Aral-Caspian Post- pliocene sea are discussed. Silurian—J. H. Panton has noted the occurrence of upwards of fifty species of corals, brachiopods, and cephalopods, with Re- ceptaculites, Beatricia and Stromatopora, ina rock of Silurian age largely used in Winnipeg as a building stone. The seven expo- Sures are described, most of them upon the level, but some ele- vated slightly above the prairie, though all were more or less covered with drift before quarrying was commenced. The American Journal of Science (April, 1886) contains another contribution to the literature of the Taconic rocks in the shape of descriptions of Lower Silurian fossils from a limestone of the original Taconic of Emmons. The report upon the fossils is by S. W. Ford and W. B. Dwight, and Professor J. D. Dana concludes from the results that these limestones of Canaan, N. Y., are of Trenton age, Carboniferous and Permian.—According to the researches of M. B. Renault, the genus Bornia must be ranged with Calamo- dendron and Arthropitus. From these genera it differs in the hill fragmentary character of its elements, but by its relief.

[September, sandstone is not very great, the stone can be distinguished by a good observer; and the question seemed to be finally set at rest by the discovery, in the same quarry, of Devonian rocks with Holoptychius, overlaid by a bed of conglomerate which graduates upward into the reptiliferous sandstone. Jurassic—The Bulletin of the French Geological Society (April, 1885) contains a note upon the zones of the inferior oolite of the southern border of the Paris basin. The zones are, M. de Gros- souvre maintains, best characterized by various species of am- monites ; lamellibranchs and gastropods having in that region too great a vertical range. Cretaceous.—M. Dollo has a note upon a tooth of Craspedodon _ lonzeensis, an ornithopod dinosaurian from the Middle Senomian of Lonzée. The tooth is furnished with large ridges on the sides and is minutely crenellated on the front upper edge of the crown. Three teeth are all that has yet been found of the genus, which raises the number of ornithopodous genera to twelve. Dollo (Ann. de la Soc. Scient. de Bruxelles) has a note upon the presence of a median basioccipital canal and two hypopasa canals in Plioplatecarpus marshi, a mosasaurid. These canals are by their discoverer believed to have served for the passage of the occipital sinus and infrajugular veins. In a skeleton of the gif species M. Dollo has also discovered an interclavicle, a bone no before known to exist in the Mosasauria. On the strength of this peculiarity M.

At one point the wire passed rough several apple trees, but I could see no traces of dead leaves there—F, E. L. Beal, Fitchburg, Mass. An Instance OF ĪNDIVIDUAL VARIATION.—Some three or four years ago I noticed in the NATURALIST the variation of the hickory trees in this vicinity as to the times of ripening their leaves. The facts then set forth were simply that upon some trees the leaves were ripe and withered into ashen-gray, while upon others they remained green until killed by the hard frosts of middle or late autumn. Others ripened all along between these extremes, _ This spring I noticed the same differences: in the times of put- ting forth their leaves. Upon some trees the leaves were fully one-third grown, while upon others, not more than a yard distant, the buds were still dormant. It was very curious to notice the changes from day to day, when “ Young leaflets deepened into greenness, And spread to the coming heat.’”?

A New ARRANGEMENT OF THE ORDERS OF Insects.—In pre- paring for the press our larger “ Zoology,” also in our “ First Lesson in Zoology,” which has just appeared from the press, we have admitted sixteen instead of eight orders of insects heretofore recognized by us. Below is given a very brief synopsis, pre- pared for popular use, of this class of insects. The Pseudoneu- roptera as the result of farther examination and reflection, are dismembered into the Platyptera (which was characterized in the Third Report U. S. Entomological Commission), the Odonata with justice, by Brauer, to a distinct order. Our reasons for this change in classification we hope to present on a future occasion. ORDERS OF INSECTS. 1.

The organs are developments of the hypodermis, are largest in the male, and the abdominal one is so thin and transparent that we can see the ventral nerve-cord through it. Branches of the trachea end in the luminous cells; they are bordered by such cells, but no end-cell on the trachea could be made out. Internal to the luminous layer is a non- luminous layer, formed by tracheal branches and irregular cell- Masses, specially rich in urates. Though the light is usually nocturnal, yet if the animal is disturbed by day it will shine less brilliantly. Even a sleeping cucuyo will show in a dark cham- ber a mild light from the dorsal organs; the light of the abdo- minal organ cannot then be seen, as the insect rests with its abdomen doubled up against its sternum. If at such time we awake it, the breathing begins, whereon the light appears in its Splendor. There are two kinds, or rather two degrees, of lumin- Osity, one soft, the other bright, which may be termed respec- tively the cell-light and the tracheal-light. One may change into the other just as the dull glare of a smith’s coals will on the action of the bellows develop into a bright flame. In the abdo- men the lateral parts begin earliest to shine, and retain their luminosity the longest, because they occupy the place nearest the lateral tracheal trunks. During flight the abdominal organ iS In Constant activity (here differing from Lampyridz in which the light is intermittent), In a dark room the light appears clear green, inclining to blue; in daylight it is yellowish. The spectrum analysis has not been satisfactorily effected; but the light seems to produce a spectrum wanting half the blue and deficient in the red. An extracted luminous organ will continue to give red light for some hours (for twenty-four hours if kept in. moist air), No light-nerves were found, and so far there was no evi- dence of the luminosity being under control of the will. It is Said that in Lampyridz the will and the nervous system control the light. In Cucuyo the abdominal light at least depends only On the respiratory center, which is in the metathoracic ganglionic mass. The expiration only of the abdomen is active, and the in- SPiration is the passive act of the abdominal muscles returning to their place of rest.

(No. 237, 1885, p. 269), I gave an account of the way in which altered plant-pig- ments take part in larval coloring. The evidence was chiefly derived from an examination of the strongly-colored blood of lik i : tains all the pigments which have passed through the walls 0 the digestive tract, for in these larve it is probable that only a inute quantity passes through as the result of any ne pe i it almost certain that the processes 1886. j Entomology. SII less likely that artificial digestion could be successfully performed than in the case of higher animals. Nevertheless, there are cer- tain ways in which the problem could be attacked with every prospect of success. (1) There are many larve which eject a green fluid from the mouth, and this fluid has the same spectrum as that of the blood (in the instance examined). It is probable that such a solution might be made by artificial digestion. (2) The blood of some large larve in which the pigments passed into the hypodermis cells might be investigated at various times after their first meal, when more extensive fluctuations might be witnessed.—Z, B. Poulton, Trans. Ent. Soc., London, 1886. TuE Fruip EJECTED BY NOTODONTIAN CATERPILLARS.—This defensive fluid, says Mr. Poulton (Trans. Ent. Soc. London, 1886, 157), as is well known, is ejected from a transversely placed aperture on the ventral surface of the prothorax immediately be- affecting litmus-paper in the most marked manner. During the last summer he found that the fluid causes violent effervescence when allowed to fall upon sodium bicarbonate, and has proved y the reduction of silver nitrate) that the fluid is formic acid. The smell is also quite characteristic, and affords an indication of the larger Proportion of acid present in the secretion. Fle also States that the freshly-made and moist cocoon of Dicranura vinula is powerfully acid to test-paper. : “In September, 1885, I found a few larve of D. furcula on wil- low, near Visp, in Switzerland, and I examined them to see if they also would eject a fluid when irritated. It was at once obvious that the aperture was present in’the same position as in D. vinula, but as the larve did not eject any fluid I applied gen- tle pressure (for this is often necessary in the case of D. vinula). To my reat surprise a complex form of “ gland” was instantly everted through the aperture, consisting of six diverging pro- cesses of a light green color, divided into two groups of three ach.

The processes vary considerably in grade of de- velopment amongst the segments, and he said he had not yet been able to make out their precise order, but he submitted a somewhat rough sketch of the appearance of the abdominal seg- ments of C. a/acta as shown by a two-inch objective. The first drawing exhibited the internal structure of the dissected portion before the fatty tissues were removed; but little of the processes could be made out from that point of view, and they were more clearly to be seen from the other aspect; also a side view show- ing the contour of the natural size. The large view of four of the Spots presents an idea of the diversity of form in the individual animal, and the two additional sketches show the processes dia- grammatically. Mr. White said that the only conclusion he could arrive at respecting them was that they were functional organs of a special nature, and he observed that he should be very glad if any one present could suggest an explanation of any such function, or throw some light upon the question of their o portions of the caterpillar had been squeezed out, these organs pose. ‘i reply to some observations from Professor Meldola, Mr. White said he had not found any similar organs in any other species, though he had looked well for them; and in reply to Mr. J. Jenner Weir, who suggested that they might act as sucker: S, he stated that the objection to that explanation was that the skin covering them was perfectly tight. There were in some instances pairs of minute holes which might communicate with a atmosphere, and probably did, but otherwise air was closed rom them. There appeared to be a motile closing of the ar- rangement of tentacles like the clasping together of fingers, but this could not apply to the open continuation of the serrated edge of tentacles above this seam of the lip, which is not unlike the labellum of some orchid. THE DARKENING OF THE HAIRS OF THE LARVA OF ACRONYCTA BEFORE Pupation.—During the past summer (1885), I noticed that the long white hairs of this larva become dark, as we i f y, before pupation, when the organism is wandering about to nd a place in which to burrow. I then remembered that I had o Plentifully upon birch and alder in the near forest. As the larva p lization of the incidental changes of color before pupation.

But such an appearance becomes very much the reverse of protective as soon as the larva moves, especially upon a dark background, and the darkening of the larval body alone would be useless, because the hairs form its most conspicuous feature—Z.

The single gland to which I refer is situated in the median dorsal line of the seventh abdominal segment, and it is everted when the larva rolls up on being disturbed. The larval surface close to the lips of the aperture seems to be extremely sensitive to tactile im- pressions.” On reading the foregoing note by Mr. E. B.

They were lighted for the first time on the even- ing of January Ist, 1886. On the night of May 8th following, a terrific thunderstorm passed over the city between the hours of 11 P.M. and midnight. During the storm- the attention of the few people who were on the street at that time was attracted to the spectacle of a great number of birds hovering about this ring of lights and dashing at them. In the morning it was discovered that hundreds of dead birds were scattered about the foot of the tower, and hundreds more were found upon the roof of the build- ing. When the workmen ascended the tower to renew the car- bons in the lights, they found many of the globes occupied by the bodies of birds, some containing as many as eight, and many of the carbons had been broken off by the birds. Over two hundred bodies were picked up by one of the workmen attached to the building, which was but a small part of those carried away by the news-boys and others in the morning. A person who saw them before any were taken away, estimated that more than a thousand were killed. But even this was but a small portion of what were seen in the air about the tower. It is to be regretted that no per- son competent to determine the species of the birds killed on this occasion, was present when they were first observed. I under- stand that a few of them afterward fell into such hands, but I have heard no report. From the testimony of those who saw them ot appear to have been, for the most part, the smaller song- s. The question arises, why was this great number of birds at- tracted on this particular night, when, during a month previous, , while the migration was going on, no birds had been seen near the lights. Tt may be that they had been driven from their course the storm, and so brought in contact with the dazzling beacon; or, perhaps, as birds are known to fly at great heights when mi- Stating, the storm caused them to fly lower, and so brought them within the fatal influence. But several other storms of nearly equal violence had taken place in the night time within the two months of April and May, and with no similar attendant phe- nomena. The most reasonable conclusion, then, seems to that the storm on the night of May 8th was coincident with a ag ha ’ of bird-migration ; that the birds flew low to get beneath e low-hanging clouds and avoid the violent winds of the upper atmosphere, and so were brought into the vicinity of the lights, i in the intense darkness of the storm, were bewildered wi oo and either rushed to an untimely fate, or fluttered help- ly about until the storm passed away, leaving the sky clear So they could see to pursue their journey —F.

It is not to be regarded as the final outcome of the ontogenesis of each individual, but passes from parent to offspring directly, being from the first present in an unmodified form in a large number, possibly in all the comatic cells. The germinative plasma persists through certain cellular series, concentrating itself anew in the embryonic cells of the new organism. Ina word, in the phylogenetic development of the organisms the germ, whose true seat has now been determined, is perpetuated through- out the whole series of successive ontogenies.

From good longitudinal sections of the spider embryo before the disappearance of the abdominal feet, it appears that the lung book may fairly be regarded as an involuted ap- pendage or appendages. Before the involution of the abdominal appendages, the epithelium covering them assumes the characters of the epithelium of the lung book. At the same time the ap- pendages become less conspicuous, and slight folds appear on their anterior faces, By the complete involution of the abdominal appendages, and the increase in the number and distinctness of the folds on their anterior faces, a lung book would be formed with its laminz directed backwards. All the stages of the process of involution were not observed, but probably in the species of spider upon which the most complete observations were made two pairs of abdominal feet are involuted. hether the conversion of the abdominal feet into the lung book is to be regarded as ar involution of certain paired append- ages, as was suggested by Lankester on theoretical grounds, or as a portion of the abdomen over which an appendage cor- responding to the operculum of Limulus extends, could not be Positively determined. ere appears, from one series of sections, to be a swelling cor- responding in position to the operculum of Limulus just in ad- vance of the involuted abdominal appenda Another point of interest in arachnid embryology is the pres- ence of a fold in the blastoderm, surrounding the cephalic region of the embryo. Balfour described this fold as a groove. Pears, however, when studied by transverse and longitudinal sec- tions to be a fold of the blastoderm. At the anterior extremity of the fold its opposite sides unite over the median line of the embryo, so that the brain is partially invested by an outer 1 or bag of epiblast formed by the united inner limbs of the °PPosite sides of the fold. , _J€ origin of this fold and the union of its opposite sides over the middle line of the embryo correspond to the amnion of in- Sects. The difference between the insect amnion and the spider amnion lies in the fact that in the former the union of the oppo- Site sides of the amniotic fold is in most cases complete through- eloped only in the head region of the embryo and coalesce at their anterior ends.—A. 7. Bruce, Ph.D. 826 General Notes. [September, PHYSIOLOGY.’ Tue DELICACY OF THE SENSE OF SMELL.—The sense of smell is probably the leading sensorial endowment in most insects, and it oes for them what sight and hearing do for man. Its potency in helping along intelligence is very great, since we know that men- tally insects stand at the head of the invertebrate, as man stands at the head of the vertebrate world. The sense of smell is prob- some twelve square feet. The sense falls in value in the Amphi- bia, reptiles and birds, but rises again in the Mammalia, though not in proportion to intelligence. Its extreme acuteness In the og, the most intelligent of animals short of Quadrumana, !s well known. In man, the sense of smell is subordinate, and even rudi- mentary. Olfaction adds to man’s enjoyment, preserves him from some dangers, but does not very much extend his knowledge of his environment. : Yet despite the comparative insignificance of this sense in man, its delicacy is most marvelous, and by it we can appreciate more minute subdivisions of matter or the impact of more infinitesimal molecular vibrations than by any other of the avenues to the rain. Professor Valentine has made some interesting and striking €x- periments in proof of this. He found that a current of air con taining 1-30,000 milligramme of bromine, or 1-500,000 ome! gramme of sulphureted hydrogen, or 1-2,000,000 milligramme ` oil of roses could be perceived by the sense of smell. He also determined that the amount of odoriferous air which must pasi over the olfactory membrane in order to excite the sense of s was from fifty to one hundred cubic centimeters (one-tenth to pee fifth of a pint). He calculated, therefore, that the actual panto of bromine necessary to excite a sense of smell was 1-6000 a A gramme, of sulphureted hydrogen 1-5000 milligramme of o roses 1-20,000 milligramme (about 1-120,000 of a grain). Two recent experimenters, E. Fisher and F. Pentzoldt, the cubic centimeter of chlorphenol, and 1-23,000,000,000 ae gr e of mercaptan, these substances could be appreciated, si it was estimated that only 1-4,600,000 milligramme of chlorp n nol, and 1-460,000,0co milligramme of mercaptan, 1S necessary pe excite a sensation of smell. There exists, therefore, a substan _ which in so small a subdivision as 1-2,760,000,000 grain, ‘This department is edited by Professor Henny SEWALL, of Ann Arbor, or not Michig2™ A TEN EELA 1886. | Psychology. 827 quite one three-billionth of a grain, is capable of calling out a nerve impulse.

Maxcy, of Gardiner, Maine, has a black-and-tan dog which is very intelligent. He has all the ac- complishments a common dog has and knows several besides. The screen door of the house opens outward, and Dick can open it from the outside, pulling it with his teeth. The other day he approached the door with a bone in his mouth. He couldn't open the door while he held the bone, and if he couldn’t have the bone he didn’t care to open it. He looked at it a minute, then laying the bone down near the door, pulled the door open and went in, He then turned and pushed the door wide open, and before it could swing to again, had grabbed up his bone and got inside.— Exchange, A bird dog owned in this town, though we doubt much if he been shot over, is in the habit of making furious dashes at the doves feeding in the streets, and of course the birds are too quick for him. The other day he watched his opportunity in this wise. The dog saw the doves, and also saw a team approaching ; he waited until the team was between himself and the birds, then € made a tremendous rush between the wheels, and the birds Not seeing his first leap were taken in a heap of surprise, and one dove was nearly captured, : eg these cases look a trifle like an exercise of the reasoning wer, _ Since the above was written (it was prepared for last week’s issue) another capital story has come to our knowledge. Dr. C. A. Packar d, of Bath, owns a setter of very fine blood, when young ` capital bird dog, but too old now to hunt. He runs with the carriage for short drives occasionally. One day when on the road poor “ Flash” had the misfortune to nearly tear out one of his nails, and the doctor was obliged to use the bone forceps to re- move the nail. Flash stood the operation “like a major,” never wincing. Not long after this the doctor heard the well-recog- _ ized rap of Flash on the office door for admission. It was opened and in came Flash, accompanied by a small dog with a bad Wound upon one leg, and Flash brought the dog up before his 828 General Notes. | September, master. The doctor attended to the binding up of the leg and then Flash went out with his little friend, probably seeing him home.—Brunswick Telegraph.

ANTHROPOLOGICAL NOMENCLATURE.—Quite frequently we have drawn attention to the necessity of a consensus among anthro- pologists as to the technical terms to be used in certain cases, and also to the precise boundaries of these terms. At the suggestion and request of a friend in Ohio, we revert to the subiect, and pre- sent in the present number a short article on names, by Mr. John Murdoch. Without pretending to legislate upon the subject, we invite the most minute criticism, promising to use the words below defined in the sense given, unless some one offers a suffi- cient reason to the contrary. harpoons fall naturally into the two following classes: 1. Toggle-harpoons, in which the head fits upon the shaft by means of a socket, and is slung in a loop at the end of the line in ‘such manner that, when plunged into an animal, the strain ee the line causes the head to become detached from the shaft an to turn like a toggle across the wound underneath the skin. 2. Barbed-harpoons, in which the head fits into a socket pr shaft, holding the animal by one or more barbs, like those oF 3 arrow. the The head of an Eskimo harpoon is always detachable pE shaft, and fastened securely to the line.

To the outer end is fitted the fore-shaft of bone or ivory, which may be simply a _ ferule of greater or less length, of the same diameter as the shaft, or may be expanded into a heavy pear-shaped knob, so as to give weight to the head of a weapon intended for darting. Into a socket in the end of the fore-shaft fits one extremity of the slen- der loose shaft, which is short in a harpoon intended solely for darting, long in one which is to be thrust through a hole in the ice. This is attached to the rest of the harpoon, usually to the fore-shaft, by the assembling line passing through holes in each and keeping the loose shaft from being dropped and lost. On the small seal-harpoon the assembling line is frequently long, and knotted also to the shaft and ice-pick, so that if, the harpoon breaks the parts are not lost. The function of the loose shaft is to prevent the harpoon from breaking with a lateral strain, while its play in its socket facili- tates the unshipping of the toggle-head. Some harpoons are still made with the fore-shaft and loose shaft in one piece, and the un- shipping of the head is provided for by the shape of the lip-end, __On the point of the loose shaft fits the tog gle-head, consisting of a body of bone or ivory in the shape of a slender conoid or hexagonal pyramid with the base beveled off so as to form a long sharp spur, the daré of which may be split into two or more pois, The body is usually somewhat flattened at right angles to the plane of the barb, but in some localities it is very much flattened in the direction of that plane, in which case it often has à pair of lateral barbs near the apex. In the apex of the body, usually at right angles to the barb, is € deep narrow blade-sht, into which fits the broad, thin, sharp ‘anceolate, or triangular blade of stone or metal. When of metal it IS Usually secured by one or more rivets. In the middle of the base is the deep shaft-socket, and through the middle of the body at right angles to the barb runs the line-hole, from which, on each side, deep longitudinal line-grooves run back to the base. the end of the line is passed through the line-hole, brought back and secured to the standing part (to use a nautical term) so that the head is slung in a loop of the line. Or the line may be joined - the ad by means of a /eader, or short line, attached as before explained to the head and knotted or spliced at the end into a ecket, in which case the line may be fastened or de- tached at pleasure. When the head is fitted upon the shaft the line is brought nearly to the middle of the latter and either knotted securely around it, fastened with a “ slippery hitch” or attached by means of a small loop or ring of ivory to a little peg, the “e-hook, pro- 830 General Notes. [September, jecting from the shaft. The last contrivance is used when the line has a float attached to it. Harpoons of the second class are more simple. The shaft is never fitted with an ice-pick, but sometimes has feathering at the butt like an arrow. The fore-shaft is usually of greater diameter than the shaft, and its socket receives the skank of the head, which has flat faces, sharp point and sides, and one or more uni- lateral or pairs of bilateral barbs. It is usually made of bone or ivory, and the /ive is fastened to it by passing the end through a hole in the shank and tying a knot on the opposite side.

M. Peixoto concludes that no type yet examined in Brazil presents the essential characters of a race. Soh As that a great mixing has long been going on among th A ienaa populations.

Netto’s contribution occupies more than half of the volume and is rich in material for future study. ornamental pottery. One of the interesting and useful character- istics of this people was the symbolical representation of the human head, which the author of the paper regards as portraitures of the people. Many pages of the memoir are occupied with the description of the markings on this pottery. mong the works of the mound-builders of the Amazon are innumerable characteristics which recall the works of mound- builders of the Mississippi valley as well as those of the civilized peoples further south. Through much of M. Netto’s comparative work we are unable to find our way, lacking the material, but every archeologist will be delighted with his figures and descrip- tions of stone implements. The existence of nephrite specimens among the objects from the shell-heaps and mounds is penn confirmation of the belief that all implements of this materia found in America are of American origin. MANUFACTURE oF Bows AND ARROWS AMONG THE Nee (Hura) AND Kenucx (Kiamatu) Inprans.—The bow-makers both these tribes are specialists, and the trade is now confined to a very few old men. I have here seen no man under forty years of agetthat could make a bow or an arrow, and only one old man who could make a stone arrow-head. To make a bow, the wood of a yew sapling two anda halft? three inches in diameter is selected and rough hewn to shape, at heart side inward and the back carefully smoothed to the wae x the back of the bow. The sinew is laid ae ja pas a green, and held in place until dry by means of a twine F In this condition itis hung in thé ieat house until the wood as thoroughly seasoned, when it is finished and strung, and in SO af cases the back varnished and painted. .The most delicate pie i the operation is to get the proper tension on the sinew bac a If too tight the wood crimps or splinters when the bow 1s eae and a lack of proper tension leaves the bow weak and wort three When the bow is seasoned it has a reverse curve of about inches, he _ The sinew for the backing and bow-string is taken from. £ back and the hind leg’of the deer at the time of killing, an¢ í pped for future use.

The sinew is slightly twisted and dried before it is placed on the bow. The glue used to fix the backing is obtained by boiling the gland of the lower jaw and the nose of the sturgeon. This is dried in balls and preserved for use, and is prepared by simply dipping it in warm water and rubbing it on the wood. The arrow shafts are usually made from the wood of the wild currant, and are worked to shape with a knife and tried by the eye. After roughing they are allowed to season and are then finished, Any curves are taken out with a straightener, made of a piece of hard wood, spindle-shaped and perforated in the. mid- e. The arrow-heads used in war and for big game are usually CALIFORNIAN AND PoLyNestAN Fisu-Hooks.—In his work on Prehistoric fishing in Europe and North America, Dr. Rau has awn attention to the similarity of South,Californian and Polyne- Sian fish-hooks of shell and bone, and he has figured a few from uth Sea islands for the sake of comparison. In consequence thereof he received, unasked, a short time ago, from the ethno- logical department of the British Museum a communication to- gether with a large plate of drawings of Polynesian fish-hooks Preserved in the museum. Some of these are strikingly alike the Californian specimens; not only does the curved points in these hooks approach very closely the shank, but they also show, like the California hooks, a barb on the outside. This analogy is the more significant, as some ethnologists, Dr. Charles Pickering mong them, have claimed a relationship between the Polynesians and South Californians. 834 Scientific News. [September, ANCIENT EGYPTIAN CLASSIFICATION OF THE Races oF MAN.— At a meeting of the London Anthropological Institute, held May 25th, Mr. R. S. Poole read a paper, reported in Mature, on the “ Ancient Egyptian Classification of the Races of Man.” This was defined by the famous subject of the four races in the tombs of the kings, at Thebes (B. C. 1400—1200). The types were (1) Egyptian, red; (2) Shemite, yellow ; (3) Libyan, white; (4) Negro, bla By comparison with monuments of the same period and of a somewhat earlier date, the first race, clearly an intermediate type, was seen to comprehend the Phenicians, the Egyptians and the people of Arabia Felix with the opposite coast. The Libyan race included an aquiline type, with marked supraorbital ridges and receding foreheads, as well as a straight-nosed type. These two types inhabited the south coast of the Mediterranean and some of the islands. The Negro race included the Negro and Nubian types. The Hittites and Hyksos, or shepherds, were as yet unclassed. Professor Flower remarked upon the resemblance of the aquiline Libyan type to that of the Neanderthal crania and the oldest European type; and saw in the Hyksos head dis- tinctly Mongolian characters. These two points are of the highest consequence in historical anthropology. oo SCIENTIFIC NEWS.' romise of what may be expected hereafter of the society, in the way of bered forty regularly enrolled members, while on some kes be alternate rofessor ical dis- De bottom of the Upper Silurian at the Delaware water a mountainous region, fine scenery and e api _ geology and botany mark the place as an extraordinar! . : * Edited by Wm.

It has donated its valuable collections to the city, which has provided the specimens with scant but pleasant apartments in the public library buildings. Detroit is a city of millionaires. Michigan is a State of boundless mineral wealth, rich in industrial woods and remarkable geological formations, and the home of ancient hiero- glyphics and ethnological remains. That scientific apathy should reign in Detroit where a large body of citizens have made millions from these resources, is at least a State disgrace. De- troit ought to support a museum devoted to the resources of the commonwealth of which it is the metropolis, especially as it is one of the oldest cities of America. — The meteor which fell near Claysville, Washington county, Pa., September 14th, was found recently by Professor J. Em- erick, of William and Mary College. The stone was found em- bedded at the base of a hill. It weighed about 200 tons, but was cracked into pieces by contact with a stratum of limestone. Its composition was chromium, nickel, aluminium, copper, magne- Sium, tin and other metals and metalloids. It contained eighty- seven per cent of iron in a metallic state. Its specific gravity Was 7412. Its elevation above the earth’s surface was established at fifty-two miles, its path nearly horizontal, its flight between five and ten seconds, its visible path 150 miles, and its velocity fifteen to twenty miles per second. _— The Chicago Academy of Sciences has been presented with the bones of an elephant supposed to be E/ephas primigenius, by Dr. E.

But the prophets saw the gods in their visions, hence the paintings contain pictures of the gods with all their hieratic belongings. The characters which perform in the great dances conducted by the priests, are representatives of the gods. In the ancient crea- tion-myth of the tribe some descriptions of the gods are incident- ally given. In the later myths, recounting the acts of the Prophets, more exact descriptions are to be found. Itis from such material as this—these oral traditions, these paintings, these ceremonies, with their hundreds of songs and elaborate unchange- able rituals, handed down from generation to generation by word of mouth and by example only—that the student must evolve the nature and scope of their worship. In one of the great ceremonies, that of the Kledji Hathal, or Gaybechy, there are, according to the circumstances, from twelve to sixteen different supernatural characters represented. Some of these, like the gaybaad, being a numerous race of divine ones, are represented by many dancers—men masked, dressed and Painted to represent gods, bearing sacred wands and talismans and symbolizing in every act and motion something in the lives “a their Prototypes ; living and breathing idols to whom the sup- pliant prays and offers his sacrifices, well knowing that he ad- with reverent prayers only his own brother or uncle masquerading in the panoply of divinity. VOL. XX.—NO. 842 Some Deities and Demons of the Navajos. (October, They begin their cosmogony with an already existing world. It is a dim world; there is light, but as yet no sun, moon or stars. It is inhabited, however, by animals or animal gods with the gift of speech and other human attributes, and by some vague gods, probably meteorological personifications, possessing more of the human than the animal character. Just when mortal man first appears on the stage it is difficult or impossible to determine. True there is a first man and a first woman, as there seem to be in nearly all Indian myths; but they do not appear as the pro- genitors of the race. The time of their beginning is not told, they are coeval with the universe, and they still live in distant lands, but not in the nether world where dead Navajos go; in short, they are immortal and eternal—they are gods. Perhaps we have in them but an extension of the zoolatry of the Indian; as the lower animals have their ancient divine prototypes, so man must have his. With a strange suggestion of the existence of a primeval Darwin, we find in the legend the animals assuming more and more the human character, until the lower worlds’ which were once peopled only by flying animals are later inhab- ited by creatures who are spoken of as men. All the beings in the first world are able to fly away on wings from the rising waters of the flood ; while in the third and fourth worlds they are obliged to seek protection in the hollow of a great reed, which grows as fast as the rising waters advance and bears the fugitives upward out of danger. Arrived on this, the fifth, world, men increased and multiplied ; but soon various enemies to the human race arose, demons an giants who devoured men, until after a while the race became nearly or quite extinct. Then came the great hero-god Wagay- nezgant, to whom I will refer later, and killed the demons. After this, by special acts of creation, new men and women were made. Possibly the first of these creations is to be regarded as the first appearance of the true mortal Indian on the earth. The Navajo has no faith in monogenesis, he believes in several special creations even for his own tribe. The process by which their rude gods made men in the old days was quite an elaborate one, and the Navajo shaman, in relating the myth, does full jur _ tice to all the difficulties. A full recital of all the symbolic mummeries that the divine beings thought it necessary tO = m in this creative act, would be at best but tedious reading. ~- 1886.] Some Deities and Demons of the Navajos. 843. brief sketch of their toils must suffice here. They took two ears of corn, one yellow and one white, the former was to become the female of the new couple and the latter the male, and it is in memory of this event, they say, that white corn is called male corn and yellow corn is called female corn to this day among the Navajos. The gods laid these ears on a large dish of pure tur- quoise, and covered them with embroidered blankets of different colors, and with sacred buckskins, 7. e., the skins of deer not slain by weapons but pursued to exhaustion and then smothered, They were laid with their points towards the east; but before they were laid down they were handed round from one god to another and each god turned them in a different direction, and this is the reason the Navajos to-day never dwell in one locality long, but wander from place to place. From time to time the benevolent god Has-chay'-el-thee peeped under the covering to see how the incubation progressed, and when the ears of corn had assumed the shape of man, the wind- god entered under the blankets to give them life. He went in at the mouth and came out at the tips of the fingers. “ Do you not believe this ?” said an old shaman to me. “ Look then at the tips of your fingers and there you will see Wiyol Bithin, the trail of the wind.” A double helical line is with the Navajos and other tribes a symbol of the whirlwind, and this symbol is impressed on the palmar aspect of the terminal joint of every human finger— Satisfactory evidence to the Navajo philosopher that the wind- god, when he gave the breath of life to man, made his exit through the finger-tips. It was the gods of the white rock crys- tal, who live in Jemez mountain, that furnished these new beings with mind, and the goddess of the grasshoppers gave them Voices. Then they rose, but at this moment a dark cloud de- Scended from the heavens and covered them as a garment. This pair became the ancestors of the 7sedyinkini, or people of the dark cliff house, the oldest gens of the present Navajo nation. The story tellers say that they are thus called because the ears of corn of which they were made were taken by the gods from certain dark cliffs. But the archzologists will be more inclined perhaps to think that the myth refers to some remnants of the ancient inhabitants of the cliff houses of Arizona, enslaved Or otherwise adopted by the conquering Navajos. The myths _, ©Ontain several other accounts of the making ot men, sometimes 844 Some Deities and Demons of the Navajos. (October, the human forms are molded of moistened corn meal, while dif- ` ferent ceremonies are performed and by different gods. But always Indian corn, in some form, is the substance used. As this has been from time immemorial the staple food of the In- dian, it is not without reason that his gods have chosen it as the proper substance fer making men. All Indian flesh is largely derived from maize. It is a difficult task to determine which one of their gods is the most potent. Religion with them, as with many other peoples, reflects their own social conditions. Their government is a strict democracy. Chiefs are at best but elders, men of temporary and ill-defined influence, whom the youngest men in the tribe may contradict and defy. There is no highest chief of the tribe. Hence their gods, as their men, stand much on a level of equality. But, as you hear the myths recited, you gain the idea that at the present day the sun-god is the most potent, though very far from being omnipotent. In the earlier days of the world, and in the lower worlds, First-man and First-woman, the Coyote and the wind-gods, and, above all, the sea-monster, appear as person- ages of greater importance. When the race came up from the fourth world to this, to escape the last flood, two very popular and much beloved persons were chosen to carry the sun and the moon, and all were deeply grieved when they departed for their distant homes beside the great eastern ocean. The sun-god dwells there now ina beautl- ful house built of turquoise. The sun is a bright shield which the god carries on his arm. The creation myth in one place = scribes with much exactness how he comes home after his day s work, how he hangs his shining shield on the wall, how it lights _ up the inside of the vast edifice, how it dangles and sways 0 the wall, going “tla, tla, tla” until at last the vibration stops and the = noise ceases. But, although they attribute great power to Chohanoat, the sun- god, it is not to him that they pray the most. Itis not he who _ takes the greatest interest in human affairs and lends his ear most readily to human supplication.

It so, but perhaps there are other reasons equally pee vill presently appear, why Æszsánatlehi, the goddess of the | ` 1886.] Some Deities and Demons of the Navajos. 845 west, is their most honored divinity. Various accounts are given of her origin. Some versions of the myth declare that she was found by First-man and First-woman ; others add that they found her at the foot of a rainbow; but the version which I regard as the most ancient and purest gives an elaborate account of a spe- cial creation, by the gods, of two divine women, one of whom was made of a piece of blue turquoise and the other of a piece of white shell, precious substances highly valued among the Navajos. The former, she of the turquoise, was Astsanat/ehi, the latter, called her sister, was Yo/kat-estsan, or White-Shell Woman, who figures as a less important character in the myths, This Estsanailehi afterwards became the wife of the sun-god, who like a true savage god is a polygamist. He has a wife in the east and another in the west; but Astsanatlehi, the goddess of the west, is beloved. She embodies attributes of various queens of heaven, of various wives of the highest deities which appear in a hundred mythologies. She has, however, none of the low jealousy and Petty spite of her sister Juno; she reminds one more of the Scan- dinavian Frigga. If one’s opinions of the Indian is based on the Popular accounts of their excessive cruelty, he will marvel that such an embodiment of benevolence can have a place in their mythology. If his estimate of the social status of the Indian ‘woman is the one most common in current literature—for she is usually represented as the over-worked slave of a pitiless master —he will marvel that to a female should be assigned such a high place among the gods. But an intimate observance of this peo- ple demonstrates that she may fairly represent the Navajo matron at her best, The name Estsanatlehi signifies the woman who changes or rejuvenates, and it is said of her that she never remains in one State, but that she grows to be an old woman, and in the course of time, at will, she becomes a young girl again, and so passes on through an endless cycle of lives, changing but never dying. In the light of this narration we see her as none other than our Own Mother Nature, the goddess of the changing year, with its youth of spring, its middle age of summer, its senility of autumn, _STowing old only to become young again. The deity of fruitful nature is, it will be admitted, fitly a goddess, and fitly also the wife of the sun, to whase potent influence she owes her fertility. Our Aryan forefathers never conceived a more consistent myth 846 Some Deities and Demons of the Navajos. (October, than this. But why is she the goddess of the west? Let it be remembered that the Navajo land lies to the west of the conti- nental divide, and slopes toward the setting sun. The Pacific, not the Atlantic, is the reservoir from which it draws its scanty mois- ture. From the west, not from the east, come the storm-clouds of the summer and the soft thawing breezes of the spring. Hence naturally this beneficent goddess, who loves her Navajo children so well, dwells in the western ocean, and from there dispenses her bounty. While she still lived in the Navajo land, and long before she journeyed to the west, she was blessed with a child whose father was the sun, at the same time her sister bore a child whose father was a water-fall, or, as some versions make it, a rain-storm. These boys were Nagaynezgani and Thédbadjischeni. One vet- sion of the myth says they were both children of Zs¢sanatlehi and the sun. They are called brothers throughout the myth; but according to the Indian system of relationship their mothers being sisters constitutes them brethren as well if they were chil- dren of one mother. These are the sacred brothers, the Dioscuri, who figure in the myths and legends of so many races not only of this continent but of the old world as well. Comparative mythologists usually regard the sacred brothers as myths of night and day, of light and darkness. Max Miiller regards this as the proper interpre- tation of the Asvinau of India, but Mr. Talboys Wheeler, in his History of India, says they are “apparently a personification of light and moisture,” and this I believe to be the true explanation of the Navajo myth, for the name Thobajischeni signifies Kins- man of the Waters, and the portion of the myth which refers " his paternity strengthens this theory. : Both of the brothers receive homage as gods of battle, but Nagaynezgani is regarded as the more potent of the two. It is to these that men offer their sacrifices and prayers when they are -~ about to go on the war-path. The sacrifices may be offered any n where, but their special shrine is at Tho-yet'-li, a place at the pa tion of two rivers in the valley of the San Juan, somewhere 1n __what is now the Territory of Utah.

Here it 1s | ey still dwell, and here their reflection is still to be seen on the . 1886, ] Some Deities and Demons of the Navajos. 847 waters of the San Juan river. This part of the myth doubtless refers to some natural phenomenon observable at this point, but I know not what it is, for I have never visited Zhoyetli. If the Navajo would have special fortune in some war, he must make a pilgrimage to the far Zoyetli and lay there the sacred cigarettes for the gods to smoke. Nagaynezgani is distinctly an Indian war-god, and the god of an especially shrewd and crafty tribe even among Indians. Like Thor he is the terror of evil spirits, but unlike Thor the evil spirits never outwit him. He too has the thunder-bolts for weap- ons, but he has not an unlimited supply of them. He must hus- band them, even as the Indian husbands his well-made arrows. His chief weapon is a great stone knife; but he depends not so much on his weapons as on his presence of mind, his craftiness, his Powers of dissimulation and, above all, on his “ medicine.” He IS No coward, no vacillator, once sped on his journey he never returns unsuccessful ; but in accomplishing his purpose he exhib- its more the character of the cunning Ulysses than of the bold Hercules, It is not, however, the warriors alone who pray to him, he is appealed to by all classes of suppliants as well, and there are Songs in his honor in all the rituals that I have yet learned. Here 'S one of the songs taken from the great rite of the Zilyidji Hathal or Mountain Chant. It is a literal translation. I have only chosen such English forms and phrases as would represent, to some ex- tent, the excellent rhythm of the original Navajo song, which is a Monologue on the part of the god: Iam the slayer of the alien gods, k afar ; From out the hole that passes through the sky, I afar ; My enemies assail me, but in vain, alk My foes of all sorts stand in fear of me, walk afar; I go on errands of a dangerous kind, afar ; Upon the highest of the mountain peaks, * I walk afar a: In the Navajo language all not of their own or cognate tribe are called axa, or na, t. e., foreigners or aliens, The minor gods °F genii are called yay or gay. Hence anagay, or alien gods, is’ 848 Some Deities and Demons of the Navajos. {October, a term applied to all those supernatural beings who once de- voured and harassed mankind. Mezga means to kill by violence, to slay, and thus we have Nagaynezgant, Slayer of the Alien Gods, a name which has its very close analogue in that of Jack the Giant Killer. His mission in life was to destroy these alien gods, which he did with a few exceptions, notable among which were the gods of cold, hunger and old age. These creatures pleaded so well for their lives; and demonstrated so well to the hero that they were not unmixed evils, that they were spared to still torment man. As a specimen of the Navajo way of reason- ing, I will relate his adventure with Sakaz’-estsan’, the Cold- woman : When he returned from his adventure with Old-age, he said to his mother, “Tell me where the Cold-woman dwells,” she did not answer him; four times he repeated the question, when she replied, “ You have done enough, my son. Seek to slay no more.” But the wind-god whispered in his ear, “ She dwells on the sum- mit of Depentsa” (the San Juan mountains). So he set forth and traveled to the north and wandered around over the highest peaks of the mountains until he, at length, encountered a wrinkled old 7 woman sitting nearly naked on a bed of snow. She had neither food, fire nor shelter, her eyes streamed tears, she shivered con- stantly and her teeth chattered so that she could scarcely talk. He knew at once that she was Sakaz-estsan. A vast crowd of snow- buntings flitted around her. These were the couriers whom she was accustomed to send forth to announce the coming of storms. They were the spies who told her what was going en in the outer world. As he approached her he said, “ I have come ona cruel errand. I have come to kill you that man may suffer no mors torture from you, or die at your hands.” “You may kill me if you will,” she chattered, “ but man will be worse off when fam d than he is now; for when I die it will be always hot, and = land will dry up, and the springs will cease to flow, and men Wi" -die of heat and thirst. You will do better if you let me live. So he lowered the arm he had raised to kill her, and reflected 4 = moment. “Grandmother, you speak the truth,” he said at late “you shall live,’ and he returned to his mother’s dwelling with- ets tephy: À ' His journeys in which he failed to listen to the voice of vever, much more numerous than those in which mercy ' her 1886. | Some Deities and Demons of the Navajos. 849 lented, and, had I space to relate them, the reader would hear of many myths with which he is already familiar in tales of our own antiquity and in the folk-lore of modern Europeans. Many char- acters with whom he has become acquainted in the pages of Grimm he would meet again, but dressed in buckskin and dis- guised in paint and feathers. The ancestral prairie wolf, the apotheosized coyote, is an im- portant figure in their mythology, as he is in the mythologies of all our aborigines to whom the coyote was known, and in their earlier fabulous ages, particularly when the Navajos dwelt in the lower worlds, he was a potent god. Closely allied to the fox in nature, he has so many mythic similarities to the reynard of European folk-lore, that we can not but suspect that our own dis- tant ancestors once worshiped the fox-god. In Arizona, as in Europe, he always appears as a cunning, deceitful mischief- maker. . It was the Coyote who brought about the expulsion of the people from the lower world. He stole the young of Ziéholtsodt, “ie sea-monster, and the latter in revenge, or in order to rescue the lost ones, caused the great floods which drove all up to the Surface of this earth. It is Coyote who is responsible for the Present irregular position of the stars. He usually had the laugh on his side as the result of his trickeries, but he was not always So fortunate. Once he went out hunting with his father-in-law, and they rested at night on the top of a rugged mountain where they lit their camp-fire and cooked some meat for supper. As they were lying down to sleep Coyote said to his companion, “ This hill is called the Hill of the Burned Moccasins.” As the old man had never heard of this extraordinary name before, he could not help Wondering at it until the wind-god whispered in his ear, “ Change your moccasins ;” so before he fell asleep he took the Coyote’s Moccasins and put them under his own head, while he put his Moccasins in place of the Coyote’s. Late in the night the Coyote Tose softly, took the moccasins from under the old man’s head and buried them in the hot embers. When they woke in the ‘Morning the old man pretended to look in vain for his lost moc- casins, “ Ah!” said Coyote, “You have forgotten that this is the Hill of the Burned Moccasins.” “ Oh! there they are under _ Your head,” said the elder; “I thank you, my son-in-law, for 850 Some Deities and Demons of the Navajos. (October, ‘taking such good care of them.” “ Yes,” said Coyote, “I have taken care of them for you; but the ground is so nice and soft on this mountain I think I shall prefer to go barefoot to-day.” Not only is the prairie-wolf a god, but nearly every animal in the Navajo land has its own apotheosized prototype, its generic ancestral god. All of these gods have their special place in the mythology of this people. Many of them have to this day spe- cial sacrifices proper to them which are prepared in the medicine- lodge and offered according to established ritual. The Navajos then are zoolaters; that is, in common with all the still pagan aboriginal races of our continent, they worship the lower animals; or perhaps it would be more proper to say they worship 200- morphic gods. A degraded form of worship no doubt many of my readers deem it; but it should be remembered that zoolatry was common to all the races of antiquity, and that a marked remnant of it is our own heritage to this day. Besides all these gods, the Navajos have a host of local divini- ties so numerous that I never hope to get a complete list of them, The Navajo land is, or was, bounded by four great mountains, Jemez on the east, San Mateo on the south, San Francisco on the west and San Juan on the north. The resident deities of these great peaks seem to receive more honor than any other place-gods, but the presiding genii of other mountains, rocks and cañons are not neglected by the devout. No people are more ingenious than our American aborigines in framing fanciful stories of locality. The Navajos particularly delight in this form of myth. Thar land abounds in strange geologic formations, in rocks fancifully sculptured by the elements, and it abounds equally in myths accounting for these features. Some recent writers have stated that our American Indians a$ a rule offer prayer and sacrifice only to evil spirits, believing that time is wasted in endeavoring to gain the favor of beings wi? are always benevolent. Among the Navajos, at least, I can sis ture to assert that such is not the case.

BY JNO. T. CAMPBELL. (Continued from p. 527, June number.) ae my article on the above subject appeared in the June Naturauist, I have received a good number of letters, both from acquaintances and strangers, some making further inquiry about some phases of the subject, some offering explanations differ- ent from mine to account for forest rotation, and still others ridi- culing my theory that seeds, especially nuts, are carried by crows, wood-peckers and squirrels sufficient to plant such large districts of young forest trees as suddenly spring up where forests of a dif- ferent timber have been cut away, or such as have sprung up on the prairies of the Wabash river second bottoms since the white settlers have stopped the burning of the prairie grass. I lave been struck with the number of persons who seem to believe (as indicated by this correspondence) that when a forest is Swept away by the axe, fire or a blight, a different kind of forest Springs up spontaneously out of the soil. I admit’ that it has much that appearance. Especially does it appear to be so with weeds and grass, but the seeds of the latter are so small that it is about impossible to keep track of them; but forest trees that grow from nuts we may more easily observe, and if we find that their seeds have been carried far beyond their fall from the parent trees, and planted so as to produce trees, we may, I think, take the Planting of weed and grass seeds for granted. Dr. Clevenger, of Chicago, in a letter says, in speaking of the oak following pine in Minnesota, where the latter was cut off of the railroad sections: “ My idea was, that during hundreds of Years the chemical constituents of the soil having been drawn upon for the sustenance of pine, something near exhaustion had Scum ed, or at least enfeeblement of the ground, and that a seed which in its development required different soil constituents; or complementary ones, would be most apt to succeed the pine.

Then why should beeches and larches 852 _ Causes of Forest Rotation. [ October, everywhere follow the oak destruction? It seems to me the true explanation comes in climatological changes as minor, and soil- chemistry changes as major causes,” I admit the puzzle the doctor produces. Perhaps neither of us is right in accounting for forest, rotation. My theory—which I have offered only as a suggestion or query—that perhaps most forest seeds will not grow in the leaf-fall of the parent tree, and that nuts are transported long distances and in great numbers by crows, woodpeckers, squirrels, &c., while it is possible, and seems to me probable, may not be the fact that accounts for oak follow- ing pine in Minnesota in the manner stated. But I must be allowed to believe a few days longer that an oak starts from an acorn. Í It is remarkable how often we all (and many very intelligent and scientific persons are included) ponder, wonder and speculate about a phenomenon, the evidence to solve which lies at our feet. If the doctor, while on the ground, had examined a few of the infant oaks, I think he would have found an acorn attached. And if he had, the only unsolved question remaining would be—How did the acorn get there? As it is, the first question to settle 1s whether the oak came from an acorn or spontaneously from ie ground. In my locality the acorn and the dark mold-cast whic it leaves in the ground can be identified as late as the third year after sprouting, e Professor George K. Greene, of New Albany, Indiana, writes: “If you were to visit the section of country in Harrison gaar Indiana, called the “barrens,” you would find an area of T thousands of acres all grown up with post oaks (Quercus e There are citizens residing in the vicinity who came there $ E there was no timber on the ground.

There the hens laid about two thousand eggs a day for about a week, while the boat was being repaired, making about fourteen thousand eggs laid. The crows carried these eggs —how many I can’t say—southward across the creek and buried them in Huxford’s field, more than a half mile distant. That was in early spring. Soon after Huxford and his boys broke that field for corn, and the plow turned up hundreds of eggs, and per- haps thousands, as they were too numerous to think of counting. When the broken ground was afterward furrowed off for planting, ’ ’ many More eggs were exposed, and after the corn came up and = Was being plowed, hundreds more were exposed, Very probably the plows exposed less than two-thirds of those buried, as the plow-cut would go below the depth likely to be buried. Hux- fords took their dinners to this field, and they cooked the eggs thus found by the fire where they made their coffee, and the eggs remained good till the first plowing of the corn in early May, when they became tired of them and ceased to notice them fur- ther. John Huxford, a wealthy farmer of this county, and one of the boys who plowed the field, told me about finding and using the eggs The “stoving” of Williams’ chicken boat I myself remember, as I then lived with an uncle on Sugar creek, d not more than three miles distant from the field. . Might this not be a good way to preserve eggs? The field | as dry, alluvial, rather sandy soil. ; . Suppose the eggs had been acorns, and the field had not been | disturbed with the plow, and also suppose the rank bottom-weeds * Since writing the above, I have seen and talked again with Mr. Huxford, and find that I am mistaken about an immaterial fact. It was not the boat that was in- Jared on the mill-dam, but one that was built there several years later. The farmers brought their chickens in before the boat was ready, and turned them loose in Cheezem’s orchard on the south side of Sugar creek. The crows carried the eggs _ 8Cross to the north side of the creek, and buried them in the Chatsey.field (which Was sold for taxes, and Huxford bought it). The balance of the statement is correct. Presume I inferred the stove beat, because it occurred at the same place. I have told this circumstances often, and have found people who manifested some _ _Pucism, because of its rare occurrence. But I have also found several other per who have found eggs buried in the ground, and they also say the eggs appeared ; ‘be sound when found.

[October, had exercised polite forbearance and kept out of the way ; would there not have been founded a dense oak forest ? In the fall of 1876 and winter and spring of 1877, I was sur- veying a line of railroad in Southern Illinois. About five miles west of Benton, the county seat of Franklin county, the line of survey cut across peninsulas of prairie extending into the timber, and likewise peninsulas of timber extending into the prairie. These are called arms of prairie and points of timber. The old timber followed up the small streams into the prairie. The buf- falo and deer, in past time, kept the grass eaten and tramped down along the water-courses where they drank, thus greatly reducing if not entirely preventing the destructive prairie fires from consuming the young trees; hence the points of timber fol- lowing up the streams. In the locality I am describing the tim ber was almost exclusively white oak. After the settlers stopped the prairie fires, these points of timber began to widen and crowd on the prairie, and in the last forty to fifty years the young oaks had extended out about a half mile from the old timber, and they ranged in height from about fifty feet next to the old trees, to the infants just emerging from the ground out at the frontier. At that frontier I saw oaks, not over four feet high, bearing acorns—keeping the seed right up to the front. In Indiana, where it is unnecessary for trees to perform the parent functions so young, I never saw a white oak less than thirty feet high bear acorns, and not then among older oaks. In the second or terrace-bottoms of the Wabash river, when the whites first settled them, they found most of them to be prairie, grown up in weeds, the prairie grass had not yet gpt pos: session of the ground except in patches. They found also scat- tering and stunted white oaks, black oaks (Quercus mg" a) and jack oaks (Quercus ferruginea). The Indians had, for an T known time, burned the prairie weeds and grass, which not a killed the infant trees but greatly injured the old ones, especially te on the south side, where to-day, notwithstanding seventy ye — o protection from fires, they still show the scars, though pe a ally healed over, and on their sawed-off stumps can be read the q _ true history of their lives.

Some one had sawed down many of the trees, for some purpose, and while waiting for a team I counted the age of the trees by the concentric annual rings on the stumps. Notwith- standing that their diameters varied trom six to twenty-two inches, every one of forty I counted was sixty-four years old, Their ages tallied with the date when the fires were suppressed. The prevailing young trees in that grove were jack oak, though there were a few white oaks, hickories, poplars and black walnuts among them, and these were as tall and thrifty as the prevailing kind. The prevailing old scattered, stunted trees of that locality were white oak, but the young white, oaks showed no lack of thrift and vigor in growing by the stumps of their parents. In Ohio, on the east side of the Big Miami river and about a half mile south of the line betweeen Hamilton and Butler coun- tes, Old Major Cilley (a relative of the Cilley who fought a duel with Graves, in Jackson’s time) undertook to clear ten acres of land on the Miami hills.

Met as we are, almost within sound of the cataract, we are tempted to ask con- cerning it many questions, to answer which would not be easy. But to us who compose the Section of Geology, Niagara is a study of peculiar interest. The structure and age of its rocks, the formation of the great gorge and the various causes that have combined to produce it, all these topics have received careful con- sideration, and though our queries are far from being fully an- swered, yet the partial replies already extorted from nature are deeply interesting and strongly suggestive. Most of these points are, however, familiar to geologists, and I do not therefore propose to dwell upon them. They have already claimed and will again claim our attention. But there is one both curious and interesting, to which I wish to refer for a few minutes. In the study of history it is often both entertaining and eae tive to stop in one’s regular course, and dropping the thread the narrative of actual facts, to consider what might have been the course of events had certain great and critical occurrences not happened at all, or happened in a different manner OF under different conditions. These “might have beens B i e though of course impossible, are not necessarily useless to th shows US on how slender a thread have depended most momentous t? _ The delay of a few hours, the failure of an apparently gi ant coincidence would in many cases, so far as we can , na : 1A paper read in abstract before the Geological section of the A.

And in like manner in geology, by stopping to think, not on what has hap- pened but on what might have happened, we sometimes discover a whole train of consequences flowing from some apparently in- significant cause which might seemingly just as well have hap- pened differently or have not happened at all. To one of these geological “ might have beens” I venture to ask the attention of interest, seeing that, as I have already said, we are met on this classic ground in a city whose destiny—whose very existence I may say—was determined by the possibility to which I wish to allude. lar hydr ographical features on the surface of our earth. A great Part, perhaps nearly a half of all the fresh water on the planet, is dammed up on the top of a table land between five and six hun- dred feet above the sea. At least this is true of the four upper ) Members of the chain, Erie, Huron, Michigan and Superior.

The relationship of these two cities to one a other is not accidental or determined by man, it is based on a geologica] causes over which man has had little ór no control. a Yet a geological study of the region shows us that solid as is the > 98 which stand the destinies of these two cities, there yet ie been critical epochs in the development of the lake district when a very slight difference would have been sufficient to change, “ven to reverse their relations to one another. é IL . | o N pe Present lowest point in the water-shed or rim of the K sia *X.—No. x. 57 ~ “ What Might Have Been.” 857 the section to-day, in the hope that it will not be quite without — The Great lakes of North America are one of the most singu- : There are, however, two of these low places that involve inter- _ ar ~t. ; : Ye 7 The channel of the Niagara river at Black rock of course te basin.

Any one who has been oe va to the outlet has observed that the land on bog sidesis ` 858 : Buffalo and Chicago, or [ October, flat and raised only a feet feet above the water. Now Lake Michigan is only ten feet above Lake Erie, and the land behind Chicago is not more than twelve feet above Lake Michigan on the water-shed between it and the Mississippi basin. This low place on the river is therefore less than twenty-five feet above the water level at Black rock. It follows then that a dam of that height across the river at Buffalo would stop its flow and throw the stream over the low ridge at Chicago into the Des Plaines and the Mississippi. In like manner a cut sufficiently large through this ridge would drain off the water and leave Niagara dry. Chicago would then be the outlet and Buffalo would lie at the head of lake-navigation. Such is the delicacy of the natural ' adjustment that has determined the relation of the two cities. : We may liken the lakes to a fountain-basin having two notches in ` its rim of about the same depth. The slightest tilt may suffice to throw all the waste water over either of these notches and leave the other dry. _ But a dam of the size imagined would bea task of vast mag- nitude. This is true if regarded as a work of human engineer- ing. But we all know that at no distant date, geologically speak- ae ing, the whole region in question and much more of the northern =e i part of the country was covered with a sheet of ice, and that this = — ice moved immense quantities of earth, sand and stone from _ place to place, depositing them far from their previous resting spots. — Sometimes this great transporting agent dropped its load of wreckage in long lines across the country, as may be seen 1? ~ the great terminal moraine recently traced from Long island Chamberlin, Upham and others.

Things were not always as ‘ they now aré. If the equilibrium in the drainage of these lakes ___- iS now so delicate, there was a time when it was more delicate still, and when no man could have determined in which direction the outflow would ultimately go. There was a time when the - whole northern part of the continent was covered with ice. As the climate grew warmer this great ice-sheet drew back. Its edge retreated northward slowly exposing the underlying ground. _ In this way Lake Erie and adjoining country were step by step freed from their icy covering. When the ice had melted suffi- ciently the Niagara river began to flow. Into all the details of its early course I cannot enter. Many of them are still uncertain. _ Butthere came a time when the level of Lake Ontario was low- ered sufficiently to allow the water to pass into it from Lake, Erie. Then the Niagara river was born and the direction of the lake drainage established. Then began the flow of the most _ beautiful river of the continent, the St. Lawrence, with its clear green water, seldom sullied, and its almost unvarying level both in summer and winter. Now there is ample evidence that in former days the level of = the Niagara river was much higher than it now is.

To this question only one answer seems possible. The dam was the ridge of Queenston heights, now forty feet above the lake-level. Here is a barrier sufficient to confine the water till it reached the required height. But the objection naturally rises: If the crest of the Silurian escarpment at Lewiston is forty feet above Lake Erie, how could the river take its course in that direction and not over w Chi- H cago ridge fifteen feet lower ? a Three answers are possible. ist. The point at which the river crossed the ridge must have been rather lower than the adjacent portions. A stream always chooses the lowest ground. Now it is just possible that this =` point was so much below the rest of the ridge that it was lower than the notch at Chicago, and therefore determined the outflow in the northeasterly direction. This, however hardly amounts to _ a probability, and certainly deserves no more than mention. 2d. Most geologists are agreed that during , the ice age the northern or north-eastern part of the continent was depressed much below its present level—in some places many hundred feet below it—and that as the ice age passed away it slowly recov- | ~ ered nearly its former elevation. The presence of recent arctic d shells on the tops of hills, as at Mount Royal, Montreal, is decis 44 ive proof of this. I will not now discuss the cause, it does not — concern the subject. But in view of the fact that the ridge at Queenston is far to the east and somewhat to the north of Chi- _ cago there is nothing improbable in the supposition that it was lower in depression and later in reélevation. Hence at the time _ in question it may have been so far below its present height as t° have been actually the lower of the two, and have thus deter - mined the outflow of the water by the ordinary laws of drainage: . on then the river was capable of cutting it down by erosion aS — fast as it rose by continental elevation, the channel once estab- lished would be permanently maintained.

The water was thus ponded back and could not flow over the low dam at Chicago because of the existence of a high ice-dam at Mackinaw. It was therefore compelled to rise until it was high enough to overflow at the next low point—the ridge of Queenston—at whatever height that ridge may then have stood. ; IV: _ The relationship then of Buffalo and Chicago as the outlet and the head of lake navigation depends on a series of geological changes whose results are so nearly in equilibrium that at certain €pochs a trifle would have been sufficient to reverse them.

Of these studies by far the most important are those detailed in Dr. William Patten’s “Eyes of Mollusks and Arthropods” ee zool., Stat. Neapel, vi, pp. 542>756. pls. XXVINI-XXXII, : e paper is far too long for complete abstract here, = pur some of the more important points relative to the compound eye may be useful in supplementing the statements in the manuals of comparative anatomy. Incidentally it may be remarked that the matter pertaining to the eyes of mollusks is equally valuable. As described in our hand-books, our knowledge of the eyes © : Crustacea, spiders and insects is based on Grenacher’s classic “ Se- 1organ der Arthropoden ” (1879), and no one (Graber Berar ıs ventured to criticise his results. Not so Dr. Patten. He has shown that Grenacher is wrong in many fundamental points, aod that his conception of these organs is in some respects so erroneous as to be all but worthless. The writer, in passing, may remark that > has had occasion, in studies in a somewhat different direction, verify many of Patten’s statements, and so far as he has gone upon the eyes of Arthropods, some of which have mate- can confirm them.

On the external surface of the compound eye is the facetted chitinous cornea, each facet of which is regarded as a lens (2). Immediately beneath this comes a layer of epidermal (hypoder- mal) cells, ¢, the existence of which was utterly ignored by Grenacher. These secrete the cornea. Next in order are some cells (retinophorze, r) which are rather complex in their structure and relations. There are four of these to each facet, and they lie exactly below the correspond- ng epidermal cells. The nuclei are placed in the outer ends, and thence the protoplasm runs back- Wards to the basal limit of the ret- inal portion of the eye marked by the line at in the figure. A short distance from the surface they contract to form a slender stalk or style (s), and these enlarge, in à graceful manner, to form a ped- Xcel (9), = y thin, and the space be- tween the four cells which make up one optic element, or ‘om- atidium,’ is occupied by a trans- Parent body, the crystalline cone ).

It is, however, with regard to the pedicel that one of Dr. Patten’s most important discoveries were made. According to Grenacher, this part (his rhabdom) is secreted by the surrounding pigment cells, but Dr. Patten claims that it is in reality but the coalesced proximal ends of the four retinophore. Surrounding the portions of the eye already described are a varying number of pigment cells (about sixteen in Crangon); around the nucleus these are large, but at either extremity they thin out into fine threads or rods which, according to Dr. Patten, _ extend, like the retinophorz, from the epidermis to the basal ' membrane. I have not been able to trace these extensions except : in part, and hence have omitted them in the drawing. It seems | probable that a variation occurs in these rods with the species, f _ though Dr, Patten (p. 637) is inclined to the contrary view. | At the base of the ommatidium a large nerve fiber (æ) is seen coming from the deeper portion to the base of the pedicel. Ac- cording to Patten this divides just before reaching the basal mem- — q brane, and gives off branches to each of the cells (pigment cells, retinophorz) composing the optic element. And farther, branches go to adjacent elements so that each ommatidium receives Its | “nerve supply from four different main bundles. The arrangement of these is very complex, and need not be described. The fiber, a however, which penetrates the axis of the pedicel seems of more 1 importance to a conception of the phenomenon of vision, and l -hence a word is necessary. It runs through the pedicel and é © Style and penetrates the crystalline cone, where it gives off fine _ fibrillae which radiate in every direction towards the outer wall. _ These are points which seem to have escaped all previous a servers, The writer has traced the axial fiber into the cone, bu Tas not seen the other details. Of the various theories and conclusions advanced by Mr. ra ten as results of his studies, we have room to mention but three - First, the existence of the radiating fibers in the crystalline con® t ua e compensation for lack of adjustment, for no "a e the image produced by the lens may fall, it will fall 1 1886,] The Arthropod Eye. 865 discredit on the “ mosaic” theory of the vision of the compound eye, a theory that already was too open to objection to be im- plicitly accepted. Lastly, a point to be referred to again, Dr. be regarded as evolved by a coalescence of ocelli. A second important paper on the Arthropod eye has already been mentioned in the pages of this magazine, but its connection with the subject in hand will excuse its being brought up again. 5 Though several authors have mentioned facts in the development _ ofthe arthropod eye—some, like Bobretzky, giving details of _____importance—Mr. Locy was the first to indicate the most import- _ ant feature in the process. In his paper entitled “ Observations _ On the development of Agelena nevia” (Bulletin Mus. Comp, a Zool., x11, pp. 63-103, 12 pls., 1886), he shows that in an early = Stage the eyes appear as local thickenings of the epidermis fol- lowed by an invagination of these thickened portions which thus come to lie beneath the surface. The pouches thus formed, one for each eye, are then cut off from the parent layer, and we have now to deal with three layers. From the outer (epidermal) arises = Was not clearly determined) while the fate of the inner layer _ Was not traced. Locy points out that as a result of this mode of development, one supposed difference between the eyes of artho- pods and those of vertebrates disappears, and the rays of light traverse the retinal elements of the one group in exactly the same direction with regard to their origin as they do in the other. _ Sedgwick (Quart. Jour. Micros. Sci., xxv, 1886) was the first to point out that the eye in Peripatus was developed from an in- a le epithelium outside the lens of the adult eye, while the inner L wall Joins the cerebrum and gives rise to the retina. Hence, says _ >edgwick, the eye of Peripatus is a cerebral eye. : same genus (Entwicklungsgeschichte von Peripatus, 11 Theil. Patten comes to the conclusion that the compound eye can not the cuticle, cuticular lens and vitreous body of the adult; from. the middle arises the retinal elements of the adult (exactly how. Kennel has also studied the development of the eye in the | 9. z, z. Inst. Würzburg, viii, pp. 1-93, pls. 6, 1886), and gives _ APP: 31-33) further details.

The outer wall of this sac is described as forming — a pee 866 | | The Arthropod Eye. This is the most important difference from Sedgwick’s very brief account. Certainly Kennel’s figures do not support the view that we have here to do with a ‘cerebral eye ;’ but it must be borne in mind that he and Sedgwick are studying different species. Next comes a preliminary communication on the development of the ocelli of Hymenoptera, by Carriére (Zoologischer Anzei- ger, IX, pp. 496-500, 1886). Here the optic epidermis becomes at first two cells deep, and then these become obliquely invagi- nated, both layers retaining their “ normal” position. The outer layer forms the lens-generating cells, the inner the retina-form- ing ones. The cells which are not invaginated become elon- ' gate and, together with the invaginated lens-building cells, form the corneal lens. These cells never lose their connection with the epidermis while those of the retina’do. The cavity of in- vagination does not close up but is occupied by the corneal. lens. -~ Thus runs Carriére’s account; but it is very difficult to under- stand it, as it is not illustrated. = Thave now a few observations of my own to record. In Cran- gon the eyes arise from invaginated pits, and here as in the spr der, Agelena, we have three layers to deal with. These are the unmodified epidermal layer and the two walls of the invaginated te pouch. The one of these latter which comes to be the more external - I have termed the retinogen because from it arises the retinal ele- as ‘ments; the other, from analogous reasons, is the gangliogen. So _ far the account is closely similar to that of Locy as outlined above. I have, however, been able to trace the development of versely, each giving origin to five cells which also lie in a radius f the eye. Of these the outer forms the retinophora : ure above while the others develop into the pigment cells. , | of the structures embraced in the bracket zg in the figure are , all the parts of the adult eye, which in outline is as follows.

I hope soon tq publish a À detailed account of my results with figures which will make clear ~ all the points indicated above. nated pit shows conclusively that this organ could not have _ arisen from a confluence of ocelli, but must have had its origin from the division of a simple eye in some respects like that of a Spider. Farther, the close correspondence observable in the development of the eye of a spider and that of a crustacean, as outlined above, and the difference of both from that of Peripatus I took last year (Inter-relationships of Arthropods, this journal, XIX, pp. 560-567; and Embryology of Limulus, Quart. Jour. cros, Sci., xxv, pp. 52 1-576) that the group Tracheata is not a natural one, and that the spiders are far more closely related to the Crustacea than they are to the Hexapods, with which they are usually associated.

The primitive stages of creation are difficult of observation, and in many cases belong to past time. It is the completed results which first obtrude themselves on our observation, and which attract our attention by their beauty and other remarkable characteristics. It is the desire to possess in its storehouses these varied objects, the wish to classify them in some manageable form, which generally actuates the mind in its first excursions into the field of natural history.

Its occurrence naturally excites inquiry as to the possibility of our being more frequently visited than heretofore by this scourge. The numerous earth-trembles destruction as has visited Charleston we must, if possible, provide. It is well known that there are lines of abrupt change of the geological structure of the earth’s crust, which are known as faults. These are more or less elongated fractures, on one side of which the strata occupy a much higher position than they do on the other. The depressed side may not receive deposits of Much thickness subsequent to the fracture. If in this case the elevated Side is not removed by erosion, a range of monoclinal _ Mountains is the result. If on the other hand deposits are laid _ Gown on the depressed area, and the elevated tract is mowed down by “frost and fire,” the mountain range disappears and none but the geologist can detect the fault or fissure. ; “he shrinkage of the earth is supposed to have been the cause “teas elevation of many mountain ranges, which are wrinkles of ate nearly always produced.

The presence of water-power or of tide-water, or the conjunction of both, has determined their location. Other conveniences make them desi- rable dwelling places. Such is the equal accessibility of the fruit and vegetable products of the plains with the grazing and dairy products of the hills. Such the equal accessibility of sea-shore and elevated places of summer resort. Professor Cope pointed out this interesting geological position of our Eastern cities sev- eral years ago. The position has, however, the disadvantage of being on the line of fracture of the border of the continent. This line is the hinge on which the flatter region of the coast has in past geologi- cal ages moved up and down. Many times this region has been = submerged, ard as many times it has been elevated above the ~ sea-level. More than half of it in the latitude of New Jersey, that is, a width of one hundred miles, is submerged at the present time. Its sea-border from New Jersey to Florida has been slowly creeping westward, since observations began to be made on our coast. The most exact of these observations have been made by Professor Geo. H. Cook, on the coast of New Jersey.

The biographic sketches pre- sented of each of the governors from 1767 to 1820 are highly interesting, and gives us a curious insight into Californian social ife as it was a century ago; they were Portola, Barri, de Neve, Fages, Romeu, Arrillaga, Borica, Arrillaga again, Arguello the Elder, and Sola, whose rule was ended by the war of Mexican independence. -The three concluding sections of Vol. 1 are devoted to the passive element in the great drama of colonial history (in which the gente de razón seemed to be the only motors); the Indians, their exterior, customs and manners, settlements and languages. No classification of them after scientific (racial or linguistic) principles was attempted, although we have had dates enough to do this for the last ten years; but a profusion of ethnographic details gives a graphic idea of what the Indians were in those times. In the description of their mythology too much promi- nence is given to Father Boscana’s report, whose tribe at San Juan Capistrano, on the coast, formed a small portion of the aborigines only, and is by no means typical, for the Shoshoni race to which they pertain is an intrusive people coming from the “Interior Basin” (Nevada, Utah, Idaho, Wyoming).

C. S. Lehr- man, in three different treatises (2, 3, 4), brought together all the hitherto known observations and arguments, treated them criti- cally, and completed them by his own extended studies. Lehrman adopted the opinions of Reimarus, Baster, Duméril and Schelver, | that the stigmata presented the most convenient place for the site of the organs of smell; but he is the first who sought to 4 ord a basis for these views by new experiments and also by = atomical data. Regarding the antenne he was familiar with a = Number of anatomical details which in part had already been dis- covered before he wrote, viz, the entrance of a nerve from the ran into each antennz,? the existence of muscles (Comparetti) and “vessels ” (Bonsdorf) in them, etc. Cuvier followed through- cut the lead of Lehrman, but Latreille? returned to the view of different Journals, considered the mouth of Arthropods as l Probable site of the sense of smell, an opinion which, before his j ‘ime, Huber, in his experiments on bees, had thought to be cor- _ ‘fect. In 1811 Rosenthal (5) published his discovery of an un- doubted organ of smell at the base of the inner antennz of crabs, and expressed his Opinion that in the fly-like animals the sense of smell was probably localized in the folded frontal membrane ove the base of the antennz. This last conclusion seemed so logical to his contemporaries that even Burmeister, in his Hand- his ead of bees, for the author himself afterwards acknowle ged + discovery to be erroneous.

Up to that date there was an uncertainty as to the seat of the organs both of smell and hearing. Fabricius (57), indeed, had already, in 1783, thought he had found an organ of Miller, however, was doubtful, from the fact that the nerve pass- ing to this organ arose, not from the brain, but from the third thoracic ganglion; but, notwithstanding, he remarks: “ Perhaps we have not found the organ of hearing in insects because we sought for it in the head.” This discovery was afterwards con- siderably broadened and extended by Siebold’s work," for the views of these naturalists on the seat of both organs had a definite : influence, especially in Germany. At present, indeed, Miller's i hypothesis stood in complete contradiction, so that during the _ following decennial was presented anew the picture of opposing ` observations and opinions as to the nature of the organs of n While Robineau-Desvoidy, at the end of the twentieth year, @ also later, in different writings (27, 34), strove energetically m ~ the olfactory nature of the antennæ, Strauss-Dürkheim held fa -to the view that the tracheæ possessed the function under dis- able 1, 52-87, 1844 ee kheim + Considérations générales sur ‘Anatomie Comps T aa boi a ‘ | 1886.] Entomology. 893 which seemed to assign the seat of the sense of smell to the an- enne.

Siebold and Stannius (1848), in their valuable Lehrbuch er vergleichenden Anatomie (p. 581), remarked that “organs of smell have not yet with certainty been discovered in these animals,” These naturalists were more happy with the crabs, whose organs of smell, with Rosenthal, they localized in the vesicle at Cee these cavities as possessing the function of hearing. ; phe following decennial was of marked importance in the judg- _ lent of many disputed questions.

As for the Crustacea, it was through Huxley,’ and still more through Leuckart,‘ that the evidence was afforded that Rosen- thal’s—also adopted as such by Blainville—olfactory organ at the base of the inner antenne should be regarded as an apparatus of hearing.

According to this author the mature worms and their eggs are coughed out of the throat of the infested fowl and the disease is spread by its associates picking them up along with their food or by drinking water in which the eggs may have hatched into larvae. No sug- gestion is allowed of any intermediate host. Mr. H. D. Walker, in an apparently carefully prepared paper on this subject (Bulle- tin Buffalo Society Nat. Sciences, v, pp. 49-71, 1886) details many experiments which he has tried, and several of them point very strongly to the conclusion that the earth-worm may, in many cases, play a part in the distribution of the pest. The em- bryos have been found living in the earth-worm at all seasons of the year, and earth-worms from infested localities, when fed to chickens, almost invariably produce the disease. Dr. Walker has also produced the disease in robins, and claims to have found the embryo of the lung-worm of calves (Strongylus micrurus) in the _ earth-worm. 1886.) E es -i The first casual supposition that he must have been a stow-a-way brought from port, must be acknowledged, on further considera- tion, as unsupported by fact. The date of. sailing, April 28th, was too late to support the probability of such an origin, all golden plovers having probably migrated from semi-tropical California to their northern breeding grounds ata much earlier date. Then the existence of such a Stow-a-way on board, undiscoverd for eight days, was at best im- probable ; for had starvation not forced an earlier discovery, the numerous cats and dogs on board would have inevitably flushed the bird. The condition of our visitor when discovered, and his ultimate fate, also preclude the possibility of his having traversed by steam power the distance from shore to mid-Pacific. o have reached us from the southward he must have flown Over I100 miles in the very teeth of a protracted and violent gale, a feat we may well set aside as impossible.

(October, + NOTES ON THE ZOOLOGICAL GARDENS AT ANTWERP AND LON- pon.—The Zoological Gardens at Antwerp contain at present one great mammalian curiosity, the Anoa of Celebes, a creature something between an ox and an antelope. The gardens are tolerably rich in antelopes generally, also in carnivores, The series of cassowaries is more complete than that of the London Zoological Gardens, and there is a very full list of raptores. The collection at Antwerp is really a fine one for the size of the city, only one-fourth that of Philadelphia, which with diffi- culty supports its “ Zoo.” oth these gardens and those of London have an example of the Lycaon, or South African hunting-dog. The great attraction of the London Zoo is a young chimpanzee, var. tschego (Sima calva), the first specimen of the species that has been taken alive. When caught she was two years old, and is now more than five. Lively, sly and full of fun, this young creature is quite a contrast to the usual listless ape of the menageries, and the great differ- -ence leads one to believe that idiosyncracy or ill-health, or a com- bination of the two, are the causes of the apathy so generally _ exhibited by man’s nearest relatives when in confinement. This animal is as full of tricks as any of the smaller monkeys. She will play with visitors very gently until she has gained their con- fidence, and will then suddenly seize a hat, bonnet or other _ removable article.

Association for the Adv. of Science a Paper on the fissures of the Carnivora. Since that time he has Prepared for the museum of Cornell University many human brains, foetal as well as adult, and of several races; has examined- nearly all the literature of the subject and published several Papers on special points, the latest being “ On the paroccirital, a newly recognized fissural integer” (Jour. of Nerv. and Mental Visease, June, 1886), and communications before the recent meet- ing of the Am. Neurol. Assoc. While far from satisfied on cer- tain matters, since each fissure should be monographed, the con- clusions now presented are, he believes, worthy of consideration. The study of the human fissures should be preceded by the study J - > by learning certain fissures before others. The “landmarks” bc ne continued from the presylvian fissure.

The skeleton, mus- cles and nerves of this organ, according to Albrecht, belong to the extremities. Dr. C. Hartlaub has (Zoclogischen Jahr- bichern, Band 1) given the results of an investigation of the speci- mens of manatees in various European myseums. He fully establishes the specific difference between the African M. sene- galensis and the American M. latirostris, and describes for the first time the skull of the South American M. inunguis, a species -absolutely ignored by most naturalists, but the distinctness of — which he proves.

In criticising the apparatus used for testing acuteness of sight, Dr. Brudenell Carter drew attention to the difference between . testing the acuteness of vision and the acuteness of perception of slight differences of the intensity of light. He contended that nothing was an accurate test of acuteness of vision unless it called upon the person tested to see the separateness of two or more objects, such as spots, which were separated from each other by intervals equal to their own diameters. : Mr. Galton draws attention to the apparatus devised by Mr. Cattell, an American, now assistant in Professor Wundt’s Labora- tory, at Leipzig, for testing the color and the sound sense.—7F.

Tae CepHALic InpEx.—The two essentials to a correct system of obtaining the rates of the length to the width of the skull are (1) that the measures should always be taken upon exactly the same points, and (2) that the fractional limits of the terms doli- chocephalic, mesaticephalic, and brachycephalic should be the same for all investigators. Now, great efforts have been made in France and Germany to achieve these results, and Dr. Garson, 1n England, following the instructions of the Anthropological In- stitute, has conducted an extensive correspondence to the same | end, and an international agreement has been reached, as fol- 4 lows: : i 1.

Dr. Tylor seems to fall in with this view, since he says: “ The Melanesian and Polynesian languages are of one family, but the Melanesian preserves earlier and more per- fect forms, the Polynesian being a group of much broken down and comparatively modern dialects spread recently by emigrants.” On the other hand Professor Keane. suggested that if Mr. Cod- rington is correct in assuming the original unity of Malayo- Polynesian and Melanesian speech, all our conclusions regarding the relative value of physical and linguistic types will have to be reconsidered.

Dissecting Pans.—The most satisfactory material for the “filling” to dissecting pans is undoubtedly bees-wax, and for ordinary purposes it should be made black by having thoroughly Stirred into it while melted a quantity of lamp-black. This mass, “tun” into suitably-shaped tin pans—provided with narrow ledges f — soldered to the inside just below the prospective surface of the wax, to prevent its floating in the dissecting fluid—is serviceable for a time, but is destined sooner or later to become worthless, owing to the inevitable rusting of the pan. Fortunately there have come into the market, within a year or two, heavy glass dishes (they are of various proportions) with short legs at the four corners, which are suitable in shape for dissecting pans. €y Present the advantages of admitting more light upon the object and of not rusting. The wax may be prevented from floating in the dissecting fluid by pouring into the melted wax in € dish a sufficient quantity of shot to give the desired specific gravity to the whole mass. Since these dishes are apparently $ «cast in molds and are presumably not of the best quality of glass, some care should be used to prevent breakage. This can * be readily accomplished by floating the glass dish in a pan of water, and gradually raising the temperature of the water to near the boiling point. “The hot wax then poured into the glass will hot be likely to break it.

CARVILL LEWIS. 4 ()BSERVATIONS extending over several years upon glacial E phenomena on both sides of the Atlantic had convinced the =- author of the essential identity of these phenomena; and the object of this paper was to show that the glacial deposits of Great Britain and Ireland, like those of America, may be interpreted __ Most satisfactorily by considering them with reference to a series z of great terminal moraines, which both define confluent lobes of ice, and often mark the line separating the glaciated from the non- glaciated areas. : ; „€ paper began with a sketch of recent investigations upon _ the glaciation of North America, with special reference to the — Significance of the terminal moraines discovered within the last — 2 few years.

In its advance this ice- sheet probably met and amalgamated with a number of already existing local ‘glacial systems, and it was suggested that there was no necessity for assuming either an extraordinary thickness of ice at the pole or great and unequal elevations and depressions of land. Detailed studies made by the author in Ireland, in 1885, had shown remarkably similar glacial phenomena. The large ice-sheet which covered the greater part of Ireland was composed of confluent glaciers, while distinct and local gla- cial systems occurred in the non-glaciated area. The principal _ ice-sheet resembled that of America in having for its center a _ great inland depression surrounded by a rim of mountains. _ These appear to have given rise to the first glaciers, which after uniting poured outwards in all directions. Great lobes from this | i Tak ice-sheet flowed westward out uf the Shannon and out of Galway, 7 = Clew, Sligo and Donegal bays, northward out of Loughs Swilly f < -and Foyle, and south-eastward out of Dundalk and Dublin bays, ~ -while to the south the ice-sheet abutted against the M ullaghareirk, _ | _ Galty and Wicklow mountains or died out in the plains. _ i ~ Whether it stopped among the mountains or in the lowlands its edge was approximately outlined by unusual accumulations of drift and boulders, representing the terminal moraines. As in - America, this outer moraine was least distinct in the lowlands, and pn often bordered by an outer fringe of drift several miles ‘ in wid ; ic cus of an east and west line extending from Tralee to Wex- word i is a non-glaciated zone free from drift.

The Irish ice-sheet f seemed to have been joined at its north-eastern corner by ice coming from Scotland across the, North channel. All the evi- dence collected indicates that a mass of Scotch ice, reinforced by that of Ireland and England, filled the Irish sea, overriding the Isle of Man and Anglesey, and extending at least as far south as ‘Bray Head, south of Dublin. A map of the glaciation of Ireland was exhibited in which the observations of the Irish geologists and of the author were combined, in which was shown the central sheet, the five local glacial systems, all the known striæ, and the probable lines of movement as indicated by moraines, striae and the transport of erratics. The glaciation of Wales was then considered. Wales was i shown to have supported three distinct and disconnected local | Systems of glaciers, while at the same time its extreme northern * border was touched by the great ice-lobe of the Irish sea. The _ Most extensive local glaciers were those radiating from the Snow- den and Arenig region, while another set of glaciers radiated from the Plinlimmon district and the mountains of Cardiganshire, nd a third system originated among the Brenockshire beacons. a The glaciers from each of these centers transported purely local boulders and formed well-defined terminal moraines. The north- ern ice-lobe, bearing granite boulders from Scotland and shells and flints from the bed of the Irish sea, invaded the northern — coast but did not mingle with the Welsh glaciers. It smothered 2 iglesey and part of Carnarvonshire on the one side, and part of ee with far-traveled northern erratics, is heaped up in hum- ^ Mocks and irregular ridges, and is in many places as characteris- Se tically developed as. anywhere in America, It has none of the. racters of a sea-beach, although often containing broken shells alg from the Irish sea.

In Flintshire it a | 922 Comparative Studies upon the Glaciation of [November, turns southward and is magnificently developed on the eastern side of the mountains, at an elevation of over 1000 feet between Minera and Llangollen, south-west of which place it enters Eng- land. There is evidence that where the ice-sheet abutted against Wales it was about 1350 feet in thickness. This is analogous to the thickness of the ice-sheet in Pennsylvania, where the author had previously shown that it was about 1000 feet in thickness at its extreme edge and 2000 feet thick at points some eight miles back from its edge. The transport of erratics coincides with the direc- tion of striæ in Wales as elsewhere, and is at right angles to the terminal moraines. The complicated phenomena of the glaciation of England, the l subject of a voluminous literature and discordant views, had been of high interest to the author, and had led him to redouble his efforts toward its solution, He had found that it was possible ‘to accurately map the glaciated areas, to separate the deposits ` made by land ice from those due to icebergs or to torrential rivers, and to trace out a series of terminal moraines, both at the edge of the ice-sheet and at the edge of its confluent lobes. Per- haps the finest exhibition of a terminal moraine in England is m the vicinity of Ellesmere, in Shropshire. A great mass of drift several miles in width and full of erratics from Scotland and from Wales, is here heaped into conical hills which enclose “kettle holes” and lakes, and have all the characters of the kettle moraines” of Wisconsin, Like the latter, the Elles- ‘mere moraine here divides two great lobes of ice, one comms from Scotland the other from Wales. This moraine may be - traced continuously from Ellesmere eastward through Hadeley, , Macclesfield, to and along the western flank of the Pennine chain, Es AAS E SEN ae er n ; 3 q ‘ern England. From Macclesfield the same moraine was trae ‘northward past Stockport and Staley bridge to a thence to Skipton in Yorkshire.

South and east r th or g moraine no signs of glaciation were discovered, while w nd west of it there is every evidence of a continuous ice- i vering land and sea alike. The strie and the ne ae rs agree in proving a southerly and south-easterly dire? e-movement in Lancashire and Cheshire. — E 1886] North America, Great Britain and ireland. 923 1 From Skipton northward the phenomena are more complicated. 7 A tongue of ice surmounted the watershed near Skipton and È protruded down the valley of the Aire as far as Bingley, where its terminal moraine is thrown across the valley like a great dam, reminding one of similar moraine dams in several Pennsylvania valleys. A continuous moraine was traced around this Aire glacier. Another great glacier, much larger than this, descended Wensleydale and reached the plain of York. The most complex _ glacial movements in England occurred in the mountain region about the Nine Standards, where local glaciers met and were overpowered by the greater ice-sheet coming down from Cumber- nd. The ice-sheet itself was here divided, one portion going southward, the other, in company with local glaciers and laden with the well-known boulders of the “ Shap granite,” being forced eastward across Stainmoor forest into Durham and Yorkshire, l finally reaching the North sea at the mouth of the Tees. The : terminal moraine runs eastward through Kirby Ravensworth to- ward Whitby, keeping north of the Cleveland hills, and all East- ern England and south of Whitby appears to be non-glaciated. On the other hand all England north of Stainmoor forest and the fiver Tees, except the very highest points, was smothered in a =~ Saof solid ice. a . There is abundant evidence to prove that the ice-lobe filling Irish sea was thicker towards its axis than at its edges, and at the north than at its southern terminus, and that it. Was reinforced by smaller tributary ice-streams from both ok England and Ireland. It may be compared with the glacier of _ the Hudson River valley in New York, each having a maximum _ thickness of something more than 3000 feet. The erosive power. x of the ice-sheet was found to be extremely slight at its edge but _ More powerful farther north, where its action was continued for a nger Period. Towards its edge its function was to fill up ine- _ Walities rather than to level them down. It was held that most glacial lakes are due to an irregular dumping of drift rather than . coinciding With those in America to confirm this conclusion.

(November, top of the ice, a fact due to the retardation by friction of its lower layers. The author had observed the gradual upward pas- sage of sand and stones in the Grindenwald glacier, and applied the same explanation to the broken shells and flint raised from the bed of the Irish sea to the top of Moel Tryfan, to Maccles- field and to Dublin mountains. The occurrence of stratified deposits in connection with un- doubted moraines was shown to be a common’ phenomenon, and instances of stratified moraines in Switzerland, Italy, America and Wales were given. The stratification is due to waters derived from the melting ice, and is not proof of submergence, It was held that, notwithstanding a general opinion to the con- i trary, there is no evidence in Great Britain of any marine sub- = mergence greater than about 450 feet. It was expected that an _. ice-sheet advancing across a sea should deposit shell Big in its terminal moraine. _ The broad principle was enunciated that wasecéie? in Great Britain marine shells occur in glacial deposits at high levels, it can be proved both by striæ and the transport of erratics that the ice advanced on to the land from out of the sea. The shells on : Three Rock mountain, near Dublin, and in North Wales and Macclesfield, all from the Irish sea, the shells in Cumberland — x transported from Solway Firth, those on the coast of Northum- _ berland brought out of the North sea, those at Airdree, in Scot- ia Caithness from Moray firth, were among examples adduced in roof of this: principle. The improbability of a great subme gence not leaving corresponding deposits in other parts of Eng- Ber land was dwelt upon. It was also held that there was insufficient evidence of more a an one advance in the ice-sheet, although halts occurred in e - retreat.

The supposed glacial drift about Birmingham and the concentration of boulders at Wolverhamp- ton were regarded as due to the former agent, while the deposits at Cromer and the distribution of Lincolnshire chalk across Southern England was due to the latter. The supposed esker at Hunstanton was held to be simply a sea-beach, and the London drift deposits to be of aqueous origin. Thus the rival theories _ Of floating icebergs and of land glaciers were both true, the one for Middle and Southern England, the other for Scotland, Wales and the north of England ; and the line of demarkation was fixed by great terminal moraines, ‘ The paper closed with an acknowledgment of indebtedness to = the many geologists of England. and Ireland who had uniformly _ tendered most generous assistance during the above investi- gation. | a ie SOME PECULIARITIES OF THE LOCAL DRIFT OF THE ROCKY MOUNTAINS} i : BY DR.

Existing glaciers in the Wind River mountains and in the San _ Juan mountains (S. W. Colorado), enable us to witness the actual -~ production of some of these peculiar effects and to understand more clearly how defragation' has played a very important part in the rough chiseling of mountain features in the far West. The general southward trend of the glacier-cut cafions is very marked, although numerous side-gulches follow more or less “transverse courses. In Northern Wyoming, at the close of the Glacial Period, the old Tertiary lake basins were still in condition to receive and assort the material deposited by the melting ice, and the greater part of the drainage was easy, but in some cases in the interior of the mountain masses to the northward, narrow, elongated basins were ploughed out below the general . drainage, although very few of these now exist in which an out- let has not since been made. In the heart of the Wind River mountains a remarkable structuré of this kind is to be seen nearly opposite old Camp Brown, at the head of the North fork of the Popo-agie river, near the base of Fremont’s peak. Here two of these deep, narrow cafions run parallelwise for several miles, with small glaciers still acting upon their shaded sides, the drainage from one being to the Missouri tributaries, the other feeding affluents of the Colorado drainage. In South- A = ern Colorado somewhat similar features are apparent, but the ree ry much com- — The same ~~ _ Juan features are not repeated exactly in any othe : as my observation goes. The distinctive peculiarity lies m -duplex character of the erosion; that is to say, there are jas zones of glaciation vertically, the upper largely representing 7 rans portative action, the lower being eroded without re the débris to any great extent.

In the more elevated tracts, therefore, the lower portion often lay in grooves like cu/s-de-sac, and many of these exist to-day, connected with the main channels often by reversed or indirect drainage. The /ower limit of exportation, which de- fines the line of junction of the two layers, follows nearly the contour of 11,000 feet above sea-level (varying from 10,500 feet to 11,500 feet). The side-gulches, except where eroded by more recent aqueous action, commonly join the main cafions on this grade. The “timber-line” is fairly continuous with these de- bouchures, and I am satisfied that this feature has been largely instrumental in determining that sharp line of demarkation.

In those mammals whose habit it is to suckle their young standing, namely, the Ungulata, any one who has given the least thought to the subject is aware that their mammary glands are situated at the posterior part of the ventral line, 2. ¢, in the inguinal region, or groin. A striking exception to this is seen in the elephant, where these glands are located anteriorly, in the pectoro-axillary spaces. The elephant holds a unique position in nature, representing the last of a long ancestral line which attained its maximum development in the Tertiary. Its immediate progenitor most likely occupied the southern range, thus escaping extinction in the drift and glacial epochs, and carrying down to present times this highly interesting and peculiar form. With no relatives 3 extant, the elephant forms a separate and distinct order, the Pro- . d boscidia, but curiously enough possessing characters which ally e: it with the widely different Rodentia; it is herbivorous, and in , general habit and mode of life is an ungulate, in a portion of _ which otder it was usually assigned a place in the older nomen- _clature. © Tt is as an ungulate or “hoofed animal,” therefore, that the : elephant interests us, and from the fact that like all the species of that order the female is in the habit of suckling her young in the — standing posture we are led to ask ourselves the reason for the striking exception in the position of the mammary glands. It will be understood that I refer to animals which give birth as a rule to one, or at most two offspring at a time, and which conse: juently have the minimum number of glands, not to those which tter” like the hog family and present a series of glands run- ning along each side of the belly line. . In dealing with a subject of this nature we enter one of those ‘oad fields of philosophic science whose farther boundary, if eed it have any, lies far below our mental horizon.

Action and reaction between organism and environment ; the demands of increasing functional activity upon plastic tissue, and the effects of use and disuse, these are the fundamental prin- ciples involved, and we can only surmise at the primitive condi- tion of affairs from the few tangible points presented to us. By attention to the following facts we may be able to gain a few ideas which will possibly throw some light upon the subject. At the anterior end of the great arterial trunk (aorta) two branches arise (subclavian) which proceed to the fore limbs. These, in turn, give off each a branch (internal mammary) which passes down- -ward and backward along the anterior thoracic wall. At the pos- = terior end of this great trunk two other branches arise (diac), Proceeding to the hind limbs, these also giving off each an artery (superficial epigastric) which runs forward in the abdominal wall to anastomose with the terminal branches of the internal mam- Mary, thus forming an arc on each side of the ventral median’ -line from neck to groin. This we will call the mammary arc. Now it is evident that in those mammals whose glands are situ- ated solely in the pectoral region, as in Primates, Chiroptera, ele- _ Phant, etc., the internal mammary artery is the main supply of the gland ; while in those in which the structure is inguinal, as in s horse, deer, etc., the superficial epigastric is the main blood ieder, ] a an ‘Surface of the body, as in Carnivora, Suidz, etcs the entire arc of blood- vessels comes into play as a source of supply. We- nave every reason to believe that this latter state of affairs was the original arrangement of the parts, as the lowest and most y Imitive condition. As specialization proceeded a reduction in the young animal, while the rest atrophied and finally disap- h Again, when the glands are situated in a row along the under _ phosis and nutrition in their broadest sense; a study vague ancient forms now extant present this same condition correlated i Oe with plurality of young at a birth, which is also undoubtedly a ` pri i x the number of young at a birth followed, and consequently fewer : > ; nds were used ; those only which were the’ most convenient a peared from want of use.

Here the anterior glands are the ones that have been discarded. These are mere speculations, for what can we do with such a subject? Surely not discard it altogether!

BY W. F. GANONG. e L is now nearly thirty years since Littorina litorea (Linn.), the ; English periwinkle, was first reported from American waters, but the question as to whéther it has been recently introduced or 2 Was an original inhabitant of our shores is still unsettled. This mollusk, though not known by naturalists to occur upon the = Seast of Acadia and New England previous to its discovery at 3 ifax in 1857 by John Willis, is at present very abundant from _ the Gulf of St. Lawrence to Connecticut. 3 Professor Verrill (Amer. Jour. Sci., iii, 1v, p. 133, 1874) says of © iti “Tt has been supposed by several writers that this shell (Z. 4torea) has been recently and accidentally introduced from Eu- rope; but Dr. Dawson informs me that he collected it more than > ry years ago in the Gulf of St. Lawrence. It is abundant at Halifax, and we have other specimens from Kennebunkport, Me., Campton Beach, N. H., and Provincetown, Mass.

[November, interesting are the known facts in regard to the distribution and spread in America of the shell we are considering, that an in- „quiry into the nature of these facts, and a search -for an explana- tion for them becomes a matter of more than special importance, The value of the settlement of the question as to whether Litto- rina iitorea has been introduced in recent times or is a native of America, is not limited to the settlement of this fact only. It has a broader value as well, inasmuch as it has a bearing upon the science of the distribution of animals. It must be remembered that no species of animal or plant can, in the strict sense of the word, be indigenous to both Europe and America. If such were the case it would be necessary to sup- pose that the two independent lines of descent, either from a common near or remote ancestor, culminating in the species, had a followed precisely identical courses of development. The latter - would require precisely identical conditions of environment—and such we know would not exist upon two separate continents. _ Hence a shell which is common to two continents must in some way have been introduced from one to another. It may be intro- duced by the agency of man, or by purely natural and physical causes, such as ocean currents, etc. For want of a better term noS he word zzdigenous has been used in the present paper to apply os to a species introduced in past time by natural ages and now ce thoroughly established as a resident. i e Sucha species is our so-called “ native periwinkle,” Littorina _ pailiata (Say). It is common to Europe, Greenland and America, _and has existed for a long time in all three countries, being found fossil in the Post-pliocene of all of them. It will be presently 1own that this shell was probably introduced from the continent which it originated to the other by way of Greenland and Ice- _ land, and by strictly natural agencies. We therefore speak of ; indigenous to America, though whether its descent from its parent species took place here or in Europe we are unable to say. But. we hope to be able to show that Littorina litorea did not exist | i America until introduced from Europe by man, and that SH | 1857. He considered it to be indigenous to for the reason thar “some of the oldest inhabit 2 1886,] ls Littorina litorea Introduced or Indigenous ? 9 33°, have assured me that they have ‘ qften picked the periwinkle, the }_— same as the English one,’ on the shores contiguous to Halifax when they were only school-boys.” The only other evidence that has been found to show that the shell was known in Nova Scotia, previous to 1857, comes ina private letter to the writer from Mr. E. Gilpin, of Halifax. He _ Says: “ Historical evidence in the shape of old English settlers , shows it to have been known in the province as far back as 1800.” How much reliance can be placed upon the unscientific evi- dence of old settlers is a question ; but granting that they did not confound it with the native form, and that they actually saw | it previous to 1857, nothing more is proved than that the shell ‘existed in Nova Scotia some years before Willis found it. Simi. larly it may be said of the fact that Dr: Dawson “ collected it ~ More than thirty years ago in the Gulf of St. Lawrence,” that it Proves (if granted) only that thejshell was to be found there ear- lier than any published record shows. Or it may be that, if intro- duced, it was introduced at more than one point. ol It is somewhat remarkable, however, that, as will be shown farther on, no other collector found this conspicuous shell in the — gulf until after 1870, although Dr. Dawson must have found it at _ ast as early as 1844. We know that it increases with great = fapidity wherever introduced. Why then, if it existed there, did it not increase sufficiently to enable some other collector to find es it? None of the lists of Bell, Whiteaves or Dr. Dawson him- _ Self mention it until after 1870. It is to be regretted that we -~ _ have not some record of Dr. Dawson’s discovery of the shell so — far back, besides the note by Professor Verrill who doubtless Writes from memory. AE i o this shell be indigenous to our shores, it must have bed <<: Confined, previous to say 1850, exclusively to the Nova Scotia feast. That this must be so ix shown as well by other facts as | by the many lists we have of New England and Gulf of St, Law- 2 i 6 the latter could have been present but “overlooked by collectors” - ae altogether out of the question. It is a much larger and more = icuous shell than the native forms, has the same habitats, , wherever it occurs at all occurs abundantly, e p convenience we will consider these two to be distinct species, although they | i 934. Is Littorina litorea Introduced or Indigenous? {November, Among the many lists of New England shells which might be named, the following have been selected : Gould’s “ Invertebrata of Mass.,” 1st ed.

(1843) mentions Z. palliata, rudis and tene- sa as occurring “ in the greatest profusion,” but Z. /forea is not in the list. Reed’s “ Catalogue of the Shells of Mass.’’? (1845) mentions the same three but not litorea. Russell's ‘« Retrospect of some of the Shells found in Essex county, Mass.”* (1851), mentions the same three but not /torea.

I wish at present merely to put on record some additional data as to its recent progress along the coast. In 1873 it was mission, and was found sparingly at Peake’s island, Casco bay. n 1872 it was very rare at Provincetown, Mass., but in 1875 it Was common there. In 1875 it was collected by the writer at Barnstable, Mass., on the shores of Cape Cod bay, in large quan- tities. In 1879 it had become exceedingly abundant at Province- town. In 1875 our parties found two specimens only on the Southern shores of Cape Cod, at Wood’s Holl, but in 1876 it was found to be common there, and is now very abundant. The first Specimen found so far westward as New Haven was obtained by ‘Professor S, I. Smith during the past winter [’79-80]. Other sol- itary specimens have since been obtained here by E. A. Andrews | and by J. H. Emerton. It is at present exceedingly abundant at Newport, R E” It is spreading into the Gulf of St. Lawrence, too, finding prob- ably a congenial habitat in the warmer water of Northumberland straits, which contain so many southern forms. J. F. Whiteaves found it at Souris and Charlottetown, P. E. I., in 18732 Do not these facts afford an exceedingly strong argument that the shell has been introduced? Its rapid increase southward Shows that a favorable habitat was there waiting for it—a much more favorable one than the Nova Scotia coast. The conditions Which determine its spread were here af work a century ago, but it Was not found anywhere in New England. As has already been pointed out, no species of animal or plant ‘an be truly indigenous to the two continents. Tt must either ve originated in one and spread to the other, or it must have originated at some other point and spread to both. A shell such a we are considering, which is at present common to both con- tinents must either have been introduced from one to the other -Y man’s agency, or by purely natural means. If it can be shown lat the natural means did not operate in this case, it would prove at Man must have introduced it; and the stronger the proba- > ity of the former, the stronger will be that of the latter. — Winds or the agency of birds, so active in the distribution of Plants, could hardly operate upon a shell or its young.

This we find actually was the case with Z. palliata. Where it originated the writer does not know, nor does it matter in the present connection, but certain it is that it is now common to England, Greenland? Labrador? Acadia and New England. And not only does it exist in these places now, but it has fora ; long time past, for it is found fossil in Post-pliocene deposits in | England, in Southern Greenland? (Z. grénlandica = L. palliata) and in Canada, though not actually in Acadia. Dawson reports it from the Post-pliocene of Gaspé, and Lyell from Beauport* We may hence conclude that Z. palliata is, in the sense in which we have used the word, indigenous to America. But as to L. Zitorea, not only does the latest and best list of Greenland shells? make no mention of its occurrence there, nor does Packard in a list of the shells of Labrador’ (though he men- tions Z. palliata and L. rudis as “ abundant” and “not uncom mon”), but no trace of it has as yet been reported from any Post- pliocene deposits of Greenland, Labrador, Canada or New Eng- land. It is a shell much more likely to be preserved in such de- posits than LZ. palliata, being much larger and stouter—though neither, from their rock-loving nature, stand as much chance of being preserved as sand or mud-inhabiting species. All of these facts tend to show that Z. Ztorea was not introduced from one continent to the other either at the same time or by the same means as L. palliata, and that if by any unknown agency what- soever L. litorea had reached America, it must have been con- fied to Nova Scotia alone “until the middle of the Pee century.

Mr. G. F. Matthew, in his account! of investigations into an undisturbed shell-heap on the shore of Passamaquoddy bay, New Brunswick, after men- tioning the occurrence of several littoral species, says: “ The tock periwinkle (Littorina rudis) is occasionally found * * * but the common European periwinkle (Littorina Litorea), now so common on this coast, is entirely wanting.” In a private letter to the writer the same gentleman says: “I have seen no trace of L. litorea in any shell-heap.” That the Indians would have col- lected the smaller native periwinkle and other small littoral spe- cies, and not the larger English one, were the latter present, is in- conceivable, no matter whether the former had been collected for food or only accidentally introduced into the shell-heaps. The same causes should have introduced Z. /itorea if it had existed at these places. Again the conclusion is forced upon us that if the shell existed in America at the time of the formation of the shell- “Heaps, it must have been confined to Nova Scotia. We have no Published lists of shells from the Nova Scotia shell-heaps, nor as the writer been able to find by private inquiry any satisfac- tory account of them. All of the facts that we have so far mentioned in connection With this shell show that if it existed at all in America previous 0 the present century, it must have been confined to the coast of Nova Scotia, There are other general considerations which show tin all probability it did not exist there. One of these we have already mentioned—the fact that it was not introduced in same way as Z. palliata, by way of Greenland, and therefore Was probably not naturally introduced into America at all. . Many undoubtedly European species of both animals and Plant could be named which, upon their artificial or accidental troduction into this country, have driven out and well-nigh exterminated closely-allied native species. Everywhere upon the __ “ast of Nova Scotia as well as that of the rest of Acadia and New land, Z. ditorea is doing precisely this, driving out the native -~ palliata, Everywhere the native form gives way before it and _ mes rare, just in proportion as the English form becomes abundant, This fact of itself gives us strong a priori grounds * Bull, N.

(November, for believing the shell to have been recently and accidentally in- troduced, but it acquires additional force taken in connection with other facts which point to the same conclusion. But granting fora moment that the shell did exist in Nova Scotia previous to this century—where it must have been con- fined if it was in America at all—what an anomalous condition of life we have. At present, as we follow its progress southward, we find it growing more and more abundant. The writer has very frequently noticed its distribution on the Southern New Brunswick coast, but it there occurs in nothing like the profusion in which he has seen it at Nahant, Mass., or Newport, R. I. In these two places, and they are like other localities in these two States in this respect, it literally covers the rocks, the native spe- cies becoming comparatively rare. What is the meaning of the fact that it becomes more abundant southward? Can it mean anything else than that (within certain limits) as it goes south it meets with a more and more congenial habitat? If this be so, and we can see no other conclusion, it shows that L. /torea thrives better in warmer water than that of the coasts of Nova Scotia and New Brunswick, and therefore that the natural home of the species, or the place where it originated was in warmer water than that of Acadia. This conclusion is strengthened by the fact of its non-occurrence in Greenland or Labrador, to both of which places it should have been carried by the same agencies which took Z. palliata there. The latter is certainly a mor northern species than the former, and it may be that the condi- _ tions of life in these two places are altogether unsuited to the more southern Z. ditorea, in which case it could certainly not have been carried from one continent the other by way of Green- land. Zf then L. itorea existed upon the Nova Scotia coast a5 (in the sense in which we are using the word) an indigenous SP cies, it was existing without spreading under comparatively un- favorable conditions of temperature, etc., while favorable condi- tions were waiting for it not far to the southward.

Its spreading as rapidly as it has, shows that it was only waiting for the opportunity to take advan- tage of it, but why, if it is indigenous, did it not begin to spread Sooner? Surely the same causes which have carried it south since 1850 were in operation before. If they were natural, such as currents, etc., they certainly have been present substantially unchanged for centuries. Professor Verrill suggests that it may have existed formerly in Nova Scotia, but have “become more diffused in recent times by commerce.” But surely there was commerce between Nova Scotia and New England before 1868 (in which year it was first reported from Maine), and enough of it to satisfy the most exacting demands of this theory. In all Probability the rapid diffusion of the shell since 185 7 is ina measure due to both of these causes, but the fact that they did not have a like effect before, seems very strongly to show that the shell was not in Nova Scotia for them to spread. The waters which bathe the Atlantic coast of Nova Scotia are carried by the strong Fundy tides across to the New Brunswick and Maine Coasts, and if currents had anything to do with carrying L. palli- ata from one continent to Greenland and thence to the other, it should have carried the free-swimming embryos of its ally, Z. litorea, from the Nova Scotia to the New England coast. But granting again for a moment that Z. /torea has existed in Nova Scotia for an indefinitely long time as an indigenous species, we have it existing under conditions very different from those in Which it thrives in England, having, as has been shown, no con- nection with the latter, and yet retaining its specific identity. It 'S possible for a species to keep its identity in widely separated localities, where the conditions of life are not precisely the same, only by a continuous intercourse between the different localities. This is in all probability the case with Z palliata, for we find it ranging freely around the North Atlantic in England, Greenland, _“@brador, Acadia and New England, and the agencies which _ “tried it from one land to the other have in all probability been & 19 operation ever since. But with Z.

We have not been able to present any direct proof that L. Jito- rea did not exist in Nova Scotia before the present century. The testimony of the numerous lists (by independent observers, who could not have overlooked the shell had it been present) of shells on the coast of New England and New Brunswick in none of which occurs any mention of Z. /itorea, the testimony of its absence from the Post-pliocene deposits of other parts of Canada where L. palliata (along with which it always exists) has been found, the testimony of the Indian shell-heaps, into which it would certainly have been carried by the same means or for the same purpose as was Z. palliata, all of these combined afford almost absolute proof that the shell did not exist on the Atlantic coast of America outside of Nova Scotia. If these same tests could be applied directly to Nova Scotia the question would be settled as to whether it occurred there. An early list of the shells of that Province, or careful investigations into its Post-plio- cene deposits and Indian shell-heaps, would practically remove all doubt one way or the other. But the former does not exist and the latter has not been made. It must have existéd in Nova Scotia, if at all. But at the same time its absence from Greenland and Labrador, where, in accord- ance with what we know of the geographical distribution of ani- mals, it ought to occur along with Z. palliata if it is indigenous; the extreme improbability of its remaining in such a small area without spreading, with causes in existence tending to carry it from a less favorable to a more favorable habitat ; and the impos- sibility of the species remaining isolated from the parent stock in England for an indefinitely long time, and yet in spite of quite a ‘differently conditioned habitat remaining specifically identical with it, all of these facts tend to show that it did not exist even i? Nova Scotia. Is not the conclusion warranted then, that ee rina litorea is not indigenous to America, but has been recently _and artificially introduced from Europe ? 1886. ] On Lemurine Reversion in Human Dentition. 941 ON LEMURINE REVERSION IN HUMAN DENTITION. BY- Es. D. COPE, EE ONS of the molar teeth of man, given by anato- mists, differ in important respects. Thus F. Cuvier (Dents des Mammifers) states that while the crown of the first superior true molar consists of four tubercles, those of the second and third superior true molars consist of but three tubercles. In the American edition of “Sharpey and Quain’s Anatomy” it is stated that the crowns of the superior true molars of man consist of four tubercles, and the same statement is made in Allen’s late work on human anatomy. My observations having shown me that both of these descrip- tions apply correctly to certain types of dentition, I determined to examine for myself to ascertain, it possible, the extent and value of the variations thus indicated. My interest in the subject had been especially stimulated by the researches among the ex- tinct Mammalia and the results which I had derived from them. These are in brief as follows: F irst, the quadritubercular type of | molar crown illustrated by the first superior true molar of man belongs to the primitive form from which all the crested upper (lophodont) molars of the hoofed placental mammals have been derived ; and second, this quadritubercular type of molar has itself been derived from a still earlier tritubercular crown by the addition of a cusp at the posterior internal part of it. This tri- tubercular molar in the upper series has given origin directly to the superior sectorial teeth of the Creodonta and Carnivora. In the inferior series I have shown that in known placental Mam- Malia, at least, the primitive molar crown is quinquetubercular or tritubercular with a posterior heel; that this form gave origin to the inferior sectorial tooth of Carnivora by modification; and > the quadritubercular type, corresponding to the superior quad- titubercular crown, by a loss of the anterior inner angle and cusp. And from the quinque and quadritubercular types of lower molar crown the various specialized types of the ungulates have been derived. Considerable significance, therefore, attaches to the question as o whether the superior true molars of Homo sapiens are quad- "tubercular or tritubercular. The inferior molars are also either Qadritubercular or quinquetubercular, but less significance at- S to this modification than to that of the superior true molars- 942 On Lemurine Reversion in Human Dentition, (November, This is owing to two facts, viz., the fifth tubercle is not the an- terior inner which completes the anterior triangle of the primitive inferior molar, but is a median posterior, such as is not uncom- mon in Mammalia of Puerco and Eocene age; and second, be- cause this tubercle is of quite small size and is, therefore, more liable to variation from insignificant causes. In the nearest allies of man, the anthropoid apes, the superior true molars are quadritubercular, the posterior internal tubercle of the last or third molar being usually smaller than in the other molars in the chimpanzee. The inferior molars are quinquetu- bercular in the human sense, the gorilla not infrequently adding a sixth lobe on the external posterior margin of the crown. The molars of both series are quadritubercular, with an occasional posterior fifth in the inferior molars, in the Semnopithecide and Cebide, excepting the genus Pithecia of the latter, where the su- perior molars are tritubercular. The superior molars of the Ha- palidz are tritubercular. In the Lemuridz the second and third, and frequently the first superior true molars, are tritubercular. In the Tarsiida the superior true molars are tritubercular through- ` out. The superior molars of the extinct lemuroids differ like those of the recent forms. Thus in Adapis and its allies they are quadritubercular, but in Necrolemur they are tritubercular. In Chriacus (whose reference to the Lemuroidea is uncertain they are tritubercular, as is the case also with Indrodon. In Anaptomorphus they are of the true tritubercular type. This 8 the genus of Lemuroidea, which in its dental character most nearly approaches the anthropoid apes and man, as I have ae where! pointed out. The formula is I. $; C.1; Pm. $; M. 3: The canines are small and there is no diastema in either jaw. It may be readily seen in consideration of these facts that the appearance of tritubercular superior molars in the genus Homo constitutes a reversion to the lemurs, and not to the anthropoid = apes or to the monkeys proper. And among lemurs the reve" sion is most probably to that type which presents the closest f° semblance to Homo in other parts of the dentition. The goe _ which answers most nearly to this requirement among those # ~ present known is Anaptomorphus. = Imwstudying the dentition of man, I have examine _ AReport U. S. Geol. Survey Terrs. F- V.

My acknowledg- ments are due to the Board of Curators, of which Professor Leidy is chairman, for the opportunity of studying it.

The museum of the Phila- delphia College of Physicians contains the collection made by the late Professor Hyrtle, of Vienna, of crania of Eastern and Medi- terranean Europeans. In this department it is unrivaled, and I am greatly indebted to the council of the college, and its curator Dr. Guy Hinsdale, for the opportunity of examining it. Some French skulls in the University of Pennsylvania were of value in the investigation. My own collection, though small, contains a number of Maoris, Australians, Tahitians and North American Indians, which have proved to be of importance. Of English and Anglo-American crania I have been able to examine but few of what might be termed the thoroughly amalgamated race. Of the latter there are probably many crania in the war collection of the Army Medical Museum, but how free the race of each may be from foreign intermixture, of course, it is impossible to know. In Selecting such as are supposed to be “stock Americans,” those of persons with ‘English names have been preferred, although Many now true Americans are of German ancestry. In order to Increase the list of this class of examinations, I have imposed on the forbearance of my friends by frequent inspections of their dentitions in ore aperto. ; I suspect that the characters thus obtained will prove of im- Portance in a zodlogical and ethnological sense. They have been ready found to be of great fixity, and hence significance, in the wer Mammalia. The only reason why they should be less so * MM man is that the modification in reverting to the tritubereular — molar is a process of degeneracy, and may be hence supposed to less regular in its action than was the opposite process of 944 On Lemurine Reversion in Human Dentition. (November, building up, or addition of the posterior internal cusp. Some justification for a light estimate of its value may be found in the following tables. But it must be remembered that it is not always possible to determine exactly the race of the person represented by a skull even when care in its identification has been exercised. Emigration and war have constantly rendered races impure, and transplantation on a large scale has in some parts of the earth produced hybrid races. The results of a study of human crania . are sure to be more or less vitiated by these circumstances. We obtain averages rather than exact definitions. Nevertheless the extremes of the series of variations are likely to be found to be characteristic of established forms of man, and will thus justify my belief in the value of the characters presented. To ascertain the relation of these variations to the races is the object of the present enquiry. The cause of the tritubercular reversion belongs to the class of agencies active in evolution of organic types of whose real nature we know little. It can not be said to be due to a contraction of the maxillary arcade, for the Esquimaux and some other peoples which display the tritubercular dentition are not deficient in this respect. Tritubercular molars do not require less length than the quadritubercular, for the external width of the crown is the same in both cases. They require less material, however, than a quadritubercular crown, since a triangle is smaller than a square drawn on the same base line ; however in some men of the lower races who present the tritubercular molars, their outline is nearly square. The hypothesis advanced! to account for the reduction of the number and quality of human teeth observed in the higher races, as well as for the replacement of the prognathous Jaw by the orthognathous, is that such changes are due toʻa trans erence of material and of growth-energy from these parts to the superior part of the skull and its contents. The relative superiority of the dimensions of these latter parts in the higher races is supposed af account for the reduction of size of the jaws.

This represents the extreme common among the higher races. l For clearer understanding of these characters they are ar- ranged in the form of a table.

The only great 1a tition 1886, | On Lemurine Reversion in Human Dentition. 947 which presents a similar high percentage of tritubercular molars is the Esquimaux, where they occur in nineteen out of twenty- eight dentitions. The tendency is most marked in Slavs, French and Europeo-Americans, and is least marked in Greeks and Italians, and in Germans. These two subraces stand in the series between the intermediate type of the North American Indians and the other Europeans, I have seen no English dentitions. It is important to remember in this connection that the dis- tinguished ethnologist and archeologist, W. Boyd Dawkins, af- firms that the earliest inhabitants of Britain and some other parts of Europe were Esquimaux. He refers especially to the men of the caves, whose implements and arts he declares to be identical with those used by the Esquimaux of the present day? As it is evident that the lemurine or tritubercular reversion commenced with the Esquimaux, it may be that in some instances at least its appearance in men of Anglo-Saxon and other European races is due to inheritance alone. But it is reasonable to suppose that in this case, as in other evolutions, the cause which produced this modification of the Esquimaux dentition is still active, and its frequent appearance in the most civilized races may be due to this cause as well. The progressive character of the French den- tition in this respect is in broad contrast with the primitive char- acter of that of Italians and Greeks. The characters seen in the latter go far towards sustaining Professor Huxley’s hypothesis that the dark Mediterranean subraces consist of a mixture of Egyptian with the Indo-European stock. . In conclusion it may be stated that the tritubercular superior molars of man constitute a reversion to the dentition of the Lemuridz of the Eocene period of the family of Anaptomorphide. And second, that this reversion is principally seen among Esqui- maux and the Slavic, French and American branches of the European race. 1 Early Man in Britain, 1880, p. 233. : _ Structure of a sea anemone may throw light on some p 948 Editors’ Table.

This is not so; further, we main- tain that he who is engaged in advanced studies in any department of science is far better adapted for fulfilling the functions of an instructor, at least in a college, than he who is content to allow others to make his discoveries for him. An instructor, to be thoroughly qualified to instruct, should keep himself thoroughly posted onall the recent discoveries in his province. Unless he be an original investigator he will fail todoso. He will rest content with the text-books and the little he can assimilate by reading abstracts and reviews in the semi-popular scientific journals; he will lack that enthusiasm without which no good results can be expected from the student. The original investigator has that enthusiasm. Without it he could not be compelled to go through all that drudgery which is necessary to produce’ good results. The student in coming into his presence is at once inspired to work, and to be thorough in his work. The original investigator is forced to keep up with the times. He must keep himself posted as to what is going on the whole world over, in order that he may not waste his time and energies in doing what has already been thor- oughly performed.

Mitne’s EarTHQuakEs!.—This is a very timely work in view of the recent earthquake at Charleston. For this reason we shall for the use of our readers, abstract some of the leading points relating to earthquakes and their causes, which seem generally accepted and to accord with observed facts.

The sea-wave of the Iquique earthquake of May ọ, 1877, like many of its predecessors, was felt across the basin of the whole Pacific, from New Zealand in the south to Japan and Kamschatka in the north, and but for the intervention of the Eurasian and American continents would have made itself appreciable over the whole of our globe. At places on the South American coast it has been stated that the height of the waves varied from twent to eighty feet. At the Samoa islands the heights varied from six to twelve feet. In New Zealand the sea rose and fell from three to twenty feet. In Australia the heights to which the water oscil- lated were similar to those observed in New Zealand. In Japan it rose and fell from five to ten feet. In this latter country the phenomena of sea-waves which follow a destructive earthquake on the South American coast are so well known that old residents ave written to the papers announcing the probability of such occurrences having taken place some twenty-five hours previously in South America. In this way news of great calamities has been anticipated, details of which only arrived some weeks subse- quently, Just as the destructive earthquakes of South America have announced themselves, in Japan; in a like manner, the de- Structive earthquakes of Japan have announced themselves upon € tide gauges of California. Similarly, but not so frequently, disturbances shake the other oceans of the world. For example, the great earthquake of Lisbon Propagated waves to the coasts of America, taking on their jour- ney nine and a half hours. The complete set of phenomena which may accompany a vio- lent sub-marine explosion is as follows (p. 174): 2 By the initial impulse of explosion or lifting of the ground, a reat sea-wave” is generated, which travels shorewards with a velocity dependent upon its size and the depth of the ocean; at the same instant a “ sound-wave ” may be produced in the air, which travels at a quicker rate than the “ great sea-wave.” A third wave which is produced is an “earth-wave,” which will reach the shore with a velocity dependent on the intensity of the 'mpulse and the elasticity of the rocks through which it is propa- gated, This latter, which travels the fastest, may carry on its back a small “ forced sea-wave.” On reaching the shore and Passing inland, this “ earth-wave” will cause a slight recession of _ S Water as the “ forced sea-wave ” slips from its back. As these “forced sea-waves” travel they will give blows to ships beneath which they may pass, being transmitted from the . tom of the ocean to the bottom of the ships like sound -waves ‘0 water.

But out of 15,000 earthquakes observed on coast lines, only 124 were accompanied by sea-waves. Out of 1098 recorded on the west coast of South America only nineteen are said to have been accompanied by sea-waves ; but from additional facts stated, almost every severe earthquake on that coast has been accompanied by considerable agitation in the neighboring sea. “ On April 2, 1851, when many towns in Chili were destroyed, the sea was not disturbed. At the time of the great earthquake of New Zealand (June 23, 1855), although all the shocks came from the sea, yet there was no flood. The small shock of February 14, however, was accompanied by a motion in the sea.” To these facts, taken from Fuchs’ work, our author adds the fact that the Fig. 2.—Stud mill at Haywards, California, swung completely over. greater number of disturbances which are felt in the northeast of Japan, although they emanate from beneath the eos not produce any visible sea-waves.

This wave, like all the others, traveled the length and breadth of the Pacific. - “In Japan, at Hokodate, it was observed by Captain T. B. Blakiston, R. A., who very kindly gave me the following account : “On August 15, at 10.30 A.M. a series of bores or tidal-waves commenced, and lasted until 3 p.m. In ten minutes there was a difference in the sea level of ten feet, the water rising above high- water and falling below low-water mark with great rapidity.

Milne concludes, after a lengthy discussion of the facts, that the majority of earthquakes are due to explosive efforts at volcanic foci. “ The greater number of these explosions take place beneath the sea, and are probably due to the admission of water through fissures to the heated rocks beneath. A small number of earth- quakes originate at actual volcanoes. Some earthquakes are pro- duced by the sudden fracture of rocky strata or the production of faults. This may be attributable to stresses brought about by elevatory pressure. Lastly we have earthquakes due to the col- lapse of underground excavations.” The work concludes with brief chapters on earth tremors, earth pulsations and earth oscillations.

Among these were the exact trigonometrical determination of the position of light-houses, the establishment of subordinate meteorological stations to connect polar stations with those in middle latitudes; the desirability of registering the super- ficial temperature of the soil; the compilation of a universal pho- netic alphabet: the representation of mountains (in elementary atlases) by level curves; the fixation of a universal scheme of coloration for different heights, depths, and kinds of soil, and the Preparation of lists of the explorers of each country.

The topographic and geological surveys of the various countries are next taken up separately, commencing with Great Britain and its colonies. In Asia only one independent country, Japan, seems to have topographic and geologic surveys. Those which were inaugurated by Brazil, the United States of Colombia, Ecuador, Peru, Costa Rica, San Salvador, Guatemala, and Mexico were all stopped at the date of the writing ‘of the report. The maps include one of the world, showing the areas which have been trigonometrically surveyed, a more detailed map of the European surveys, and another of the United States, and several sections from the topographic maps of various European countries. he advantages of the various methods of representing relief can be studied by comparing the hachures illuminated by oblique light of the Swiss atlas with those illuminated by vertical light of that of Russia, and both with the system of curves adopted in the Spanish survey. The section from Siegfried’s atlas of Switzerland gives the slighter elevations in curves, the higher in hachures, and fulfills its purpose admirably. In the maps of Saxony curves and crayon shading are used, while in that of France five colors are used in combination with contour lines. There is unfortunately a lack of references to enable one unversed in all the varieties of topographic representation to understand them. The necessity of a consensus on the subject is evident. THE MORPHOGENY oF THE VERTEBRAL COLUMN IN THE AMNI- ota—In this brochure of thirty pages Dr. Baur gives a historical review of the opinions of anatomists as to the homologies of the vertebral segments, which are most easily distinguished among the Rhachitomous Batrachia. There have been three different j those of von Meyer, Cope and Gaudry. ker. Von Meyer regarded the intercentrum in Archegosaums as an inferior vertebral arch, corresponding below, to the neura arch above. Cope believed it to be a distinct body, intercalated between the true centra, which he regarded as represented by the two pleurocentra. Gaudry thought that the pleurocentra and inter- centrum together form a centrum, and he therefore names Copes intercentrum “ hypocentrum.” Dr. Baur shows Cope’s "E the correct one on various grounds.

[ November, GENERAL NOTES. GEOGRAPHY AND TRAVELS.' GENERAL.—In a recent number of the Mittheilungen of the Geographical Society of Vienna, Dr. Penck takes issue with the usually accepted proportions of land and water (1 to 2.76), assert- ing that the unknown regions around the poles are too extensive to permit of any reasonable approach to accuracy in this respect. M. Rambaud gives the extent and population of the French colonies, or rather possessions. Including Tonkin and Mada- gascar, these comprise about 1,800,000 square kilometers, and about twenty-four and a half millions of people. In this total the population of the French Congo possessions is not included, and Tonkin is credited with only 12,000,000 of inhabitants. The com- merce with these colonies was, in 1883, about 915,000,000 of francs. Major Feilden, naturalist of the Arctic expedition of 1875-76, has given in his adhesion to the belief that through the secular cool- ing of our planet the poles became first fitted for the reception of life; that in Palaeozoic times the north pole possessed a climate at least as warm as that now experienced at the equator, and that during the Miocene period the temperature, though gradually cooling, supported a flora which spread southwards. America.— The Xingu.—Petermann’s Mittheilungen (Nos. 5 and 6) contains a full account, with maps, of the German Xingu expe- dition of 1884. The Xingu is formed by the union of three large rivers: the Kuliseii, the Ronuro and the Batovy, the last of which falls into the Ronuro a little above its confluence with the Kali- seii, which may be considered the main stream. The expedition descended the Batovy, which flows in numerous bends through a flat country, but is intersected by many rocky strata forming rapids. After the confluence the Xingu flows through a level country till it reaches 10° S. lat. Here it enters granite hills and . the great bend of the Xingu, the cataracts upon which were explored by Prince Adalbert of Prussia in 1842-43. Within this bend the river falls 260 feet. At its confluence with the Amazons the Xingu is a mighty stream nearly five miles wide. The different branches of the Xingu are inhabited by no less than eighteen dif- _ ferent Indian tribes, though the total population does not exceed 2,000. The Suya Indians live in beehive-shaped houses with a diameter of thirty-three feet. = | American News—Lake Tahoe is dethroned from its position = as the deepest lake upon the continent, Captain Dutton having _ found a depth of 1996 feet in Crater lake, Oregon.

Mr. Bryce fears that the Burman, in spite of that vigor which has enabled him to continue dominant for two thousand years, will succumb to the more energetic Shans and Kakhyens (Singphos), now that his empire has been put an end to by the British. The Burmese occupy the upper part of the Irawadi delta, the upper valley of the Sittang, a narrow space on each side of the Irawadi in Upper Burmah, and the Moo valley, between the Irawadi and the Kyendwin. The Talaings still form the bulk of the population in the delta of the Irawadi and Sittang. The Talaings are smaller, plumper, fairer and less hard-featured than the Burmese, while the Shans are bigger and stouter than the dominant race. Mr. Bryce puts the total population at seven and a half millions, about half of them Burmese. ` the Drying up of Siberian Lakes. —The rapid drying up of the lakes of the Aral-Caspian region is not limited to the i i to it.

[ November, the area in question, revealed other and more interesting facts concerning the growth of the lodes in this restricted area. It soon became evident that the extremely peculiar topography of the country at the head of Red creek, in Ouray county, could have been produced only by the accumulative action of numerous enor- mous geysers, far more effective than those to-day at work in the Yellowstone Park, though occupying, perhaps, a less extensive basin. Probably, however, not a little of the area over which the hot spring deposits can be traced, may have been the seat of im- portant geysers. In fact, there are reasons for making this state- ment more definite, but it will be best to confine ourselves to what can be clearly described in a few words, without considera- tion of nice structural details. The upper valley of Red creek is thickly studded with mounds of varying size, but not widely different in form. All these are more or less closely connected with the present (or compara- tively recent) local drainage, which is also bounded at irregular intervals by dry pits and pools of cold water quite similar to the bowls of existing hot springs in other localities. The remarkable characteristics of this basin are the number and the magnitude of the mounds and the total absence of active thermal springs, not- withstanding the existence of such in localities not far distant, as át Ouray. The altitude of the district is from about 9500 feet to 12,000 feet, whereas few, if any, of the present hot water bowls are known above 6500 feet, hereabouts. The cañon of Red creek is undoubtedly not one wholly of aqueous erosion, but the drainage has been induced in part by seismic action, modified in an interesting manner by glacial scor- ings and subsequent diluvial deposition. The Red Mountain geyser area, as we may designate this tract, is now topograph- ically restricted, as here indicated, almost wholly to the upper portion of this interesting cañon, but it may be really separated into three well-marked basins, which formerly fed as many sepa- rate affluents of the main stream. Two of these are proven to be metalliferous, while the third is almost unexplored; though giving indications of similar character, but less promising perhaps. f The geyser areas do not seem to extend beyond the region © maximum intensity of the volcanic action in the rhy olytic period, and the ore-bodies all furnish evidence of secondary re- actions taking place in the line of a prominent fault-fissure of that age. All along this course over a considerable breadth of terri- tory, the remains of extinct thermal springs are (recognizably ) _ most abundant, but the geyser character is not noticeable far _ towards the north or south of Red peak. : f The ormations in the vein material, the aggregation id -~ the ores into bonanzas (as at the Yankee Girl, Alaska and O Lout mines, among others) with the very remarkable distribution minerals in the lodes, are but a few of the intensely interesting m 1886, | Geology and Paleontology. 965 details which can be there studied to the best advantage. Much that is there revealed has already thrown new light upon the origin and life-history of metalliferous deposits, but I cannot now touch upon these topics.' The gigantic geyser-mounds are in themselves of marked interest, not only from their great size and external configurations, but also on account of their internal structure as proven by the excavations made in some of them for mining purposes. The American Belle, Grand Prize and other mines were opened directly in mounds of this nature, and (as in many other cases where only ordinary thermal springs probably existed) caverns were invariably entered after passing through an outer shell of considerable thickness. In nearly all of these some connection with the surface was traceable by following the tracks of woodchucks, which had utilized the passages as domiciles, In the caverns, which are sometimes of large dimensions, there is usually a deposit of sulphuretted ores, with allied minerals, with a very considerable amount of yellow and red material resulting from its oxidation and the production of carbonates. _No doubt much valuable information bearing directly upon the life-history of the geyser may yet be gathered from detailed Studies in this district. But little real exploration underground las yet been accomplished, and that small amount is but par- = tially known to those who can make the best use of it for scien- _ tific purposes. All that the writer has yet observed agrees in most 2 €ssentials with what may be seen in the extinct subterranean Passages at Gardiner’s river, Wyoming, except that the metal- liferous deposits and the geyseritic relics are peculiar to the Red ountain area——Dr. Theo. B. Comstock, Champaign, Illinois. SCHLOSSER on CREODONTA AND PHENACODUS.2—Dr. Schlosser has attacked the problem of the Creodonta with his accus- tomed skill, and has thrown the additional light of his exten- šive acquaintance with mammalian anatomy on the subject. op et Seat A eee” fe ee See like him, of an order Bunotheria, but rather with Lydekker, of the order Carnivora. He does not regard them as an- Cestral to the Carnivora, but as having had a common ancestor with that order. This common ancestor he derives from hy- _ Pothetical Marsupialia with numerous temporary teeth. He ex- Cludes from the Creodonta the Hyznodontide and Muiacide, 1884-86, now running (* Metallurgy of San Juan county Ores ”’); also per previously quoted in Trans. Am. Inst.

[November, regarding both as true Carnivora; the former on account of the supposed scapholunar bone reported by Gervais, the latter on ac- count of the single flesh-tooth. He restricts the Creodonta to those forms which have two flesh-teeth, if any. From the Leptictidæ he excludes the genera Leptictis, Mesodectes, and Ictops, placing them in the Insectivora. He therefore changes the name Leptic- tidæ to Proviverridæ. Schlosser does not agree to the intro- duction to the Creodonta by Cope of the tritubercular families usually referred to the Insectivora, viz., the Talpidæ, Chryso- chloridide, Centetide, Mythomyidz. and Tupæidæ; but he does not give his reasons for this view. The following remarks may be made on the above positions of Dr. Schlosser. The supposition that Hyzenodon possesses a scapholunar bone has been shown by Professor Scott to be an error, so that this form must be retained in the Creodonta, to which it is connected by Pterodon. Specimens of Miacidz in the Princeton Museum show that this family also possessed no scapholunar bone. This, together with the non-trochlear astragalus which I have described, shows that the Miacide must also be referred to the Creodonta. These points admitted, it becomes much easier to believe that the Carnivora are the descendents of Creodonta, through the Miacidæ. (The supposed connection between Oxye- nidz and Felidz I denied in my last phylogeny in the article on Creodonta in the AMERICAN NATURALIST for 1884.) The exclu- sion of the three genera above named from the Leptictide, (Pro- viverridz) has little significance, until the reasons for separating e Creodonta from the tritubercular Insectivora can be shown. r. Schlosser’s representation of my phylogenetic views is very inaccurate, owing to a misunderstanding of the dates of publica- tion of my respective papers. The oldest of these is the Vol. 1m. Report U. S. Geol. Survey Terrs., sent to press in 1879, and not issued until February, 1885. The next in point of date are the illustrated papers on extinct Vertebrata, issued at various times in the AMERICAN NATURALIST. My latest phylogenetic opinions, delivered from fuller material and more mature reflection, were published in a paper on the “ Evolution of the Vertebrata, P ay gressive and Retrogressive,” in the February, March and Apr! f numbers of the American NATURALIST for 1885. In the last O hese papers the Lemuroidea are separated from the Bunotheria and placed in the Taxeopoda n they are allied. This does not include the Mesodonta (P elyco- dus), which being unguiculate, remains with the Bunotheria. In . paper all are derived from carnivorous Marsupialia, in accordance with the view of Hackel’s “ Schopfungsg* schichte” ae : . ‘Dr. Schlosser generously acknowledges, in another page, ie : _ prior indication of the ancestry of the Phenacodus and ae m of the horse line to his own, by Dr. J.

Amer. Philos. Soc., 1881, p. 178!—E. D. Cope. Dotto on Extinct Torrotses.— The distinguished Belgian anatomist, M. Louis Dollo, has recently published two important Papers on extinct tortoises from the Eocene formations of Bel- gium. The theme which gave rise to the first of these, is the de- scription of a new genus and species of Chelydride, Pseudo- trionyx delheidi Dollo. In preparing to do this, the author re- Views the classification of the Testudinata in an extremely able manner. He adopts the system of Cope in the main, and in giving his reasons for doing so makes an important contribution to the subject. He differs in some details from the author of that system. Thus he separates Eurysternum from the Chelydridz as type of a distinct family, because it possesses a fontanelle of the plastron ; a character which the reviewer does not regard as of family value. He also unites the Propleuride with the Cheloniidz, but as we shall see, he reéstablishes it as a sub-family in the second paper quoted, without apparently being aware of the fact. - Dollo somehow supposes that the author of the system he adopts regards the plastron of the Testudinata as homologous with the sternum of other Vertebrata, and also that the names he employs for the elements of the plastron are original with him. This is an error. The terms “ postabdominal,” etc., were introduced by the distinguished English anatomist, W. K. Parker, and the au- thor criticised by M. Dollo, has stated in one of his papers, on Which I cannot at this moment place my hand, that he adopts the views as to the homologies of the plastron, held by that authority. But M. Dollo thinks that the names Dactylosterna, Clidosterna and Lysosterna imply the erroneous homology with the sternum, and should therefore be charged. He then names thesedivisions ctyloplastra, etc. Now names ought not to be changed without tter reasons than those offered by M. Dollo, for the well-known Pprobrium scientie is the multitude ofnames. Those in question Were not given under an erroneous idea, but the word “ sterna’ Was used figuratively, just as it is in many genera of the order. As well might M. Dollo change the generic nam x es Eury- . Sternum, Pleurosternum, etc., into Euryplastron, Pleuroplastron, etc. And this our author has not yet done. _ The plates called intergular by me in Baéna appear to me to be 3 _ A0mologous with the corresponding plates in Pleurodira, although ?

Adocus, another Cryptodire genus, has a single one well developed. In his second article M. Dollo separates certain species re- ferred by. Professor Owen to the genus Chelonia, as representa- ‘tives of another genus which he names Pachyrhynchus. It is characterized by the underroofing of the posterior nares, and by the great extent of the mandibular symphysis. He regards this character as requiring the creation of a sub-family of the Cheloniidz, the Pachyrhynchine. The present writer has, however, described the same characters in two genera referred by him to the Propleuridze (Euclastes and Lyto- loma) and has referred to one of the European species (Chelone planimentum Owen—Pachyrhynchine Dollo) as presenting this character... M. Dollo’s genus is probably one of the American forms, and his Pachyrhynchinz is the Propleuride Cope. i Dollo’s family characters are, however, better than those given by Cope.—£. D. Cope.

BOTANY.! . How SHALL BOTANY BE TAUGHT IN AGRICULTURAL COLLEGES?— Numerous factors enter into the problem, such as the size of the class, the age and preparation of the students, the season of the year, the length of the college term, the probability of subsequent study, the means of illustrations which can be commanded an many other similar considerations. All of those factors are so different and so variously combined, that a method, which on the whole might be the best in some particular case, might not be good text-book is a most valuable aid. The lecture method is necessary in very large classes, but satisfactory results are rarely reached, even with the aid of copious means of illustration and a fairly good work of reference in the hands of the student. Nor is the laboratory method, pure and simple, altogether free from ob- jection. Left largely to himself to find out important facts in re- gard to the specimens he is given to study, the student is sure to go astray and waste much time, a loss needless and inexcusable. A judicious combination of the methods named would in all probability secure the best results in a majority of cases. Let me suppose the class to number from thirty to forty, com- posed of young men of average attainments and ability, and that from three to five hours per week for a year is to be given to = subject. A desirable time for beginning the work of instruction is at the opening of the winter term, which in most colleges 1S soon after New Year’s. For the first term the object is to gain 4 _ general view of plants and plant-life. The basis of the instruction _ should be lectures or talks, occupying a part of the hour, which the teacher can vary according to the needs of the class. An ex- cellent accompanying text-book is Bessey’s Essentials of Botany, _ from which pages may be occasionally assigned as a lesson to be carefully learned. Every subject taken up should be copiously = - illustrated with specimens which the student is to see and e fal _ ine for himself. Occasional days are to be set aside for care sel _ reviews of subjects already studied, and from time to time oppor y should be afforded for the examination of specimens under- scope.

Nor should the ad- vantage of giving out suitable topics or problems for the members of the class to examine and report upon, be overlooked, The skillful teacher will find no difficulty in assigning appropriate Subjects, which will require independent observation and thought on the part of the student. _A term’s work of this kind should give such a comprehensive view of plants as to make subsequent studies to the highest degree valuable and effective. A second term may be devoted mainly to the higher plants. By this time the spring has so far advanced that an abundance of mens, if thoroughly well done, is always profitable. third term may be given to questions relating to the physi- ology of plants. I do not know of any subject more important to an agricultural student than this. The instruction here must be largely in the form of lectures. Goodale’s Physiological Botany Sa most admirable work. It is perhaps too comprehensive to be Used as a text-book in ordinary classes, but would be serviceable as a work of reference. Some well arranged laboratory work in the histology of plants is very desirable as a part of the instruction in the subject now under consideration. A special effort should ae be made on the part of the teacher to illustrate his instruction aS Many experiments as possible. Many of these must be thmmenced long before they are needed for use in the class-room. e actual experiment which the class can see, is worth a large number of mere descriptions of experiments. Nor is it difficult to — devise, in a fairly equipped laboratory, especially if a bec SNe rare 'Salso available, a large number of experiments, which the student p 972 General Notes. [November, can himself conduct, make his own observation and prepare a report of the results. To my mind the scheme which I have here outlined rather than described, suggests at least a desirable method of teaching botany under the limitations named. It is capable of a great deal of modification as circumstances demand, and in the hands of a skillful teacher is likely to produce satisfactory results. In case the instructions end with the year, the student has acquired as large and useful a knowledge of plants as could reasonably be expected; and if he is to continue his studies further, he has an excellent foundation for thorough work in special subjects. I think we are all agreed there is no royal road to learning; and I am sure that to no subject is this truth more applicable than to botany. And in conclusion I would suggest that the value of any method of instruction may be tested, first, by the extent and accuracy of observation which it calls forth on the part of the student, and second, and chiefly, by the amount ‘of earnest and thorough work which it leads him to do.— Professor A. N. Prentiss, in American Horticulturist. Botanica. News.—A most important paper is now in course of publication in the Journal of the Linnean Society, beginning with the first number of Vol. xxr.

KRAEPELIN ON THE ORGANS OF SMELL IN ARTHROPODS!— To Leydig it was first given to make a decided step in ad- and Hemiptera, and which had only thus far been regarded as sense-organs, Leydig first calls attention to the widely-distributed pegs and teeth, also considering them as sense-organs. “ Olfac- tory teeth,” occurring as pale pegs, perforated at the end, on the Surface of the antennz of Crustacea, Myriopoda, Hymenoptera, Lepidoptera, Coleoptera, are easily distinguished, and besides the ‘olfactory pegs” of the palpi, may be claimed as organs of smell. ‘Ne nerve-end apparatus first discovered by Hicks in the halteres and wings, Leydig thinks should be ranked as organs of hearing. Regarding the Crustacea, Leydig, in his latest work,* gave a lasting explanation of the nature of the pale peg or cylinder on the end of the antenne which he found in new groups of this class, which was adopted by a large number of naturalists. Thus Claus,> in his different essays, expressed the view that these Ley- digian organs had the function “ of making sensible slight changes ” 1 bd “4 In the chemico-physical condition of the water. ndeed, in his * Translated by A.

Rougemont, Gam- roth,’ Hoek,® Haller and others more or less decide upon the olfactory nature of the organ of Leydig. Jourdain (40) does not accept this opinion, and Wrzésniowski’ adopted the views of Milne-Edward and La Valette. The “calceoli” of Amphipoda might be regarded as organs of smell. There was still some opposition to Leydig’s opinion that in the insects the sense of smell'is localized in the antennz (teeth and pits),and here the work of Hensen? might be mentioned, which in 1860 had a decided influence upon the conclusion of some inquiries, Thus Landois (15) denied that the antennz had the sense of smell, and declared that the pits in the antennz of the stag beetle were auditory organs. In like manner Paasch (16) rejected Ley- dig’s conclusion, while he sought to again reinstate the old opin- ion of Rosenthal as to the olfactory nature of the frontal cavity of the Diptera. In spite of the exact observations and interesting anatomical discoveries of Forel’ in ants, made in 1874, there ap- peared the great work of Wolff on the olfactory organs of bees, in which this observer, with much skill and acuteness, sought to give a basis for the hypothesis of Kirby and Spence that the seat of the sense of smell lay in the soft palatine skin of the labrum within the mouth. Joseph (18), two years later, drew attention to the stigmata as olfactory organs, referring to the olfactory gir- dle, and Forel” sought by an occasional criticism of Wolff’s con- clusions to prove experimentally the olfactory function of the antenne ; but Graber,” in his much-read book on insects, defend- ed the Wolffian “nose” in the most determined way, and denied to the antenne their so often vindicated faculty of smell. In 1879 Berté (52) thought he had observed in the antenna of the flea a distinct auditory organ, and Lubbock” considered the organs of 1 Sars: Histoire naturelle des Crustacés d’eau douce de Norvège, Christiania, I z Weismann © Ueber den Bau und der Lebenserscheinungen der Leptodora bys lina, Zeits. f. w.

In this work Graber described in Musca and other Diptera closed otocysts with otoliths and auditory hairs, as Lespé had previously done. ut Paul Mayer, in two essays (21, 53) refuted this view in a criti- cism of the opinion of Berté, referring the “ otocysts with oto- liths ” to the well-known antennal pits into which trachee might Pass. Mayer did not decide on the function of the hairs which extend to the bottom of the pits; while in the most recent re- Physiological experiments and detailed anatomical investigations Hauser sought to prove his hypothesis as Pierret, Erichson, Slater, Point of view. Ina purely anatomical aspect, especially promi- nent are his discovery of the singularly formed nerve-rods in the Pits and peg-like teeth of the Hymenoptera and their develop- ment, as well as the assertion that numerous hairs in the pits de- scribed by Leydig, Meyer, etc., should be considered as direct terminations of nervous fibers passing into the pits. In the pits he : rther, with Erichson, notices a serous fluid, which may serve as a medium for the perception of smells. Among the latest arti- cles on this subject are those of Künckel and Gazagnaire (41) which are entire anatomical, while the latest treatise of Graber on the organs of hearing in insects! opposes Hick’s theory of the olfactory function of the nerve-end apparatus in the halters, wings, Stc., and argues for the auditory nature of these structures. Fin- Smell is not localized, but spread over the whole body. Coxat GLANDS IN SPIDERS AND PERHAPS Insects.— Professor P. Bertkau reports that in a specimen of Atypus he has been able to find a distinct efferent duct for the coxal gland; it is surround- ed by the same fibrous plexus as the gland itself; in six other Specimens the duct was not to be found, though the orifice was n. This rare phenomenon may either be explained by sup- Posing that there was an abnormal retention of an organ which is in other cases absorbed, or, it may be suggested, that in adult _ *Xamples the efferent duct is regenerated from time to time, in Which case the coxal gland would not be arudimentary organ, . but One that is intermittently functional; the constant presence ~ "he orifice is an argument in favor of the latter hypothesis.

[ November, *is important to note that the orifice appears on two segments, for this indicates a repetition of the glandular organ, and is pro tanto a support to the view of Ray Lankester, that the coxal glands of Arachnids and of Limulus, are the homologues of the segmental organs of Peripatus. The author suggests that the gland at the sides of the prothorax of Avxisomorphus buprestoides, and those found by Scudder in the Phasmide, are possibly representatives of the same gland. In Mantis religiosa there is a coiled gland at the hinder side of the fore leg. Fourn. Roy. Micr. Soc., Fune, 1886. Heart oF Insects.—Miss Olga Poletajura finds that the heart of Bombus is composed of five separate tubes, which form the chambers of the organ, and that the most anterior of these is con- tinued into the aorta. Each tube narrows anteriorly so as to have the appearance of a truncated cone, while the walls become thin- ner; posteriorly it enlarges ; the anterior end passes into the pos- terior in front, and each anterior end is so flattened laterally as to ` form a vertical cleft ; the cardiac tubes are thus only united with one another at two points; the free portion forms a duct (ostium) by which the blood from the abdomen enters the heart ; the inter- nal surface of the anterior tube, and the external surface of the posterior form pouch-like safety-valves which regulate the move- ment of the blood. The heart of Cimbex is formed in essentially the same way as that of Bombus. The writer points out the dif- ferences between the accounts now given and those of such en- tomologists as Strauss, Newport, and Graber, and describes the mode by which the heart appears to perform its function; con- trary to the opinion of Strauss, the first chamber does not func- tion alone, as the propelling agent and the ostia are not perfectly closed, so that part of the blood does return to the abdominal cavity — Zool. Anzeig., ix (1886), pp. 13-5.

In this way a large number of beautiful specimens were taken which would otherwise have been quite difficult to capture. —TFoseph L. Hancock. _ ENTomotocicar Notes —At the Junemeeting of the Entomolog- ical Society of Washington, Mr. Lugger mentioned the fact that rounds, were this year uniformly sterile. He attributed this phenomenon to the inclement weather during the flowering sea- son, which prevented bees from visiting the flowers. He also farther described the mode of fertilization of the common lady’s- Slipper / Cypripedium acaule) by a species of Andrena. Mr. Lugger also remarked that a few specimens of the Euro- Pean Aphodius erraticus were first found by him in 1878 near Baltimore.

Desmospongize. Sub-class ITI, Myxospongie. Class II. Calcispongiz. The great majority of the sponges, as will be seen, belong to the Desmospongize.

[ November, New FRESH-WATER CŒLENTERATE.—Dr. Ussow describes (Ann. and Mag. Nat. Hist., xvi, p. 110, pl. Iv, 1886) a new fresh-water Coelenterate from the rivers of Russia. It is a Hy- dromedusa, but differs so from all others that it is made the type of a new genus, Polypodium. The young stages are remarkable in that they are passed as parasites in the eggs of the sterlet, about one-fifth of the eggs being thus infected. This stage is described as a cylindrical spiral twisted tube with numerous lateral buds. This feeds upon the yolk granules which are taken up by the ectodermal cells and are thence passed to the endoder- mal ones. From this is developed the free stage, which is more like a normal Hydromedusa and is provided with six, twelve or twenty-four tentacles, but lacks an umbrella. The perfect or sexual stage is not known. A full paper is promised soon. Nervous SYSTEM OF THE SEA-URCHIN.—M. H. Pronho states that if one suitably treats a portion of the integument which covers the test of Achinus acutus with chloride of gold or citric acid, numerous bluish lines connected by frequent anastomoses will become apparent; the appearance forcibly recalls that figured by Professor Loven of the peripheral nervous system of Brissop- sis lyrifera. Examined under a power of 500, the plexus will be found to consist of a large number of fibrils, and some of the principal bundles will be seen passing towards the spines and adjacent pedicellariz. The fibrils of which this plexus is formed are identical with those of the tentacular and ambulacral nerves, and each is continuous with the fiber from the ambulacral nerve which emerges from one of the tentacular pores; the plexus lies tween the external epithelium and a layer of connective tissue which sends off a number of connective bands through the meshes of the nervous plexus to support the epithelium. At the detect in the plexus, but they are very numerous and easy to see in the nerve-ring; the author does not, however, agree with Romanes in his description of these elements. M. Pronho has also been able to make out a nervous genital ring, which cor nects the five genital glands with one another and, by means © the five ambulacral trunks, with the peribuccal nervous pentagon. . — Comptes Rendus, cii ( 1886), pp. 444-6. = Tue Crustacean CARAPAx.—There seems to be a certain fatal- = ity connected with some scientific facts. Away back in 1834 vi _ late Henri Milne-Edwards had a conception of the true ga gee ogy of the crustacean carapax, and eighteen years later James ©. _ Dana still further efaborated the matter. But, notwithstanding _ the weight of their authority, their views failed to gain Ee cceptance and almost every text-book! to-day states that th 1886. } Zoology. 979 carapax of crabs and lobsters represents the coalesced terga of all the cephalic and thoracic segments, and a line crossing it is ‘ pointed out as the suture dividing the head from the thorax—the cervical suture. This view is wholly erroneous and has arisen from an attempt to trace homologies where none exist. Dr. Howard Ayers (Bulletin Essex Institute, Vol xvii, pp. 49-59, pls. U-11, 1886) has recently restated the problem and the evidence to show that the carapax is in reality to be regarded as the coal- esced terga of the antennal and mandibulary segments, and that the “cervical suture” merely indicates the line between them. His presentation of the case should be conclusive. He further shows that the parts regarded by Milne-Edwards as episterna are in reality portions of the sternum cut off by the appearance of false sutures, Fe ee Seer DEVELOPMENT OF PHyLiopops.—Claus, in the last Heft of the sixth volume of the Arbeiten zool. Inst., Wien, gives an account, illustrated with twelve plates, of the structure and development of the Phyllopod genera Branchipus and Artemia, which supple- ments his former paper published in Gottingen, 1873. He dis- cusses the segmentation and development of the body during metamorphosis, the segmentation of the mesoderm and the differ- entiation of the ectodermal and mesodermal organs, the formation of regions and the number of segments, integument, connective tissue and fat bodies, muscles, nervous system and sense organs (including the median and lateral eyes), the alimentary and excre- tory organs, heart, circulation and respiration, and the sexual or- gans, thus giving a monographic treatment of the development of the group. _ THE Rips or SPHENODON (Hatteria).—Cope! has shown that in some of the Pelycosauria the capitulum of the two-headed ribs 4S attached to the intercentrum. _, The question arose immediately: Is it not probable that the living Sphenodon with so many characters. common to the Permian Pelycosauria shows the same condition ? ._ The ribs of Sphenodon are described by Owen, Ginther and | brecht, None of these authors speak about ribs connected with _ the intercentrum (hypapophysis), but they have observed two- headed ribs in the cervicals. : _ Owen? says: “The fourth vertebra has a short pleurapophysis On each side with a bifurcate proximal end articulated by a broad tubercle to the diapophysis and by a slender neck and head to a Cleat aaa Cope, E.

In the fifth vertebra the parapophysis and dia- pophysis form together an oblique ridge, chiefly extended verti- cally, and to which the expanded head of the pleurapophysis articulates by a single surface.” Günther! says: “In one example the pleurapophysis of the fourth vertebra is not bifurcate, the lower branch being replaced by a ligament, and no trace of a parapophysis can be distin- guished.” Albrecht? says: “ Quatrième vertébre cervicale-—Diapophyses bien développées et séparées par une échancrure d’un rudiment e parapophyse.

I believe that the diapophysis consists of diapophysis only, and that the head of the rib repre- sents only the tuberculum, thecapitulum being distinct but liga- mentous, The living Sphenodon shows therefore in principle the same condition of the rib-articulation as the Permian Pelycosauria. But there are still other Sauropsida which have some of the ribs connected with the zztercentrum. Inall Crocodilia and Dinosauria the first rib of the atlas is attached to the intercentrum between the occipital condyle and the atlas. The same condition can be found in birds, where this first rib has become ligamentous, and probably in all Sauropsida with ribs connected with the Atlas. I do not doubt that the Ornithosauria show the same condition, since L. v. Ammon? has shown that the cervical ribs of Rham- Phorhynchus are like those of the crocodile.—Dr. G.

The reptiles of this sub-region, which extends into the Akhal-Tekke oasis, are, of lizards, two species of Phrynocephalus, Agama sanguinolenta and Varanus scincus; a Testudo, and the snake Waja oxiana. This oasis has a most mo- notonous landscape, but is pretty well furnished with insects, among them Julodis (3 sp.) several kinds of Ateuchus and Copris, and numerous Melanosomata. Jackals, and on the banks of the few rivers the wild cat and the Lagomys occur. The summer in this oasis is very hot; 40 Celsius in the shade is not uncommon. The summer molting of the birds is by our author attributed to this great heat. The lark has parts of its body quite bare at that season. The bulk of the birds of the oasis during the summer belong to the Aral-Caspian fauna, but others come from the moun- tains, following the rivers. Griffons, ravens, swifts and swallows live in the mountains, but descend to the plain to hunt. In the valleys of the mountains the leopard and the cheetah are rare, Hyena striata is occasional, and El/obius talpinus, several species of Erinaceus and Platycercomys and Hystrix hirsutirostris are common. The dreadful Vipera eufratica is a source o continual danger during the grape harvest of the forested upper valleys. Frotozoa—Gruber has been studying the phenomena of conju- gation as presented by Paramecium, and states that not only 1s there a union of the nuclei, but that the nucleoli “come into 1n- timate contact, copulate with each other.” He claims that the act has not only a sexual function but it plays a part in rejuvenes- cence, and that there is an exchange of protoplasm between the nucleoli. Rhizopoda.—Mr. Whitelegge enumerates twenty-four species of Rhizopoda in New South Wales, mostly identical with those found in Europe, America and India. The list includes Pelomyxa palus- tris, Rhaphidiophrys elegans, Clathrulina elegans, and Biomyxa vagans. Cælenterates—Mr. G. H. Fowler (Quart. Jour. Mic.

Soc.) first gives a condensed historical review of the various works on earthworms, and a chronological record of the discovery of new facts; then briefly enumerates and describes all known earthworms; then takes the various organs in order, and points out their variations, and lastly describes some new species. Among these is Micro- cheta rappi from South Africa, a worm three feet six inches long, and therefore comparable with Antzus and Titanus from South America. Another species of Microchzta from Natal follows, and IS succeeded by Urobenus (1 sp.), Diachzta (1 sp.), and Trigaster (I sp.) all new genera. Mr. Weldon contributes to the same journal an account of Dinophilus gigas, found at Penzance, En- gland. Three species of the genus were previously known. Dinophilus is stated on the one hand to be related to the Arch- annelids, while on the other it retains many features characteristic of the common ancestor of these groups, in which Mr. Weldon includes Crustacea, Mollusca and Rotifera, as well as Chztopoda and Gephyrea. The relations of the body cavity, excretory system and pharynx point to a Turbellarian origin. The tapeworm, Tenta Jilrcollis, has been known as a parasite of the sticklebacks (Gasterosteus).

Mollusca—M. Th. Barrois gives in his thesis before the Faculty of Sciences of Paris an account of the foot-glands and aquiferous pores of the lamellibranchs.. There is great variety in the byssus- forming apparatus, but Cardium edule furnishes a good typica example. The byssus is a glandular product, and does not con- sist of dried or chitinized muscular fibers. C. edule has a simple byssus of one filament, while Lima, Pinna, and Avicula have many. In Arca the filaments are united into a mass, and Anomia has a similar mass which is encrusted with calcareous salts, sO 45 to appear as an ossicle. M. Barrois describes the muscles of the byssus; the cavity of the byssus, which receives the secretion ; the glands of the cavity; the byssal canal; the groove, and se _ glands of the groove. In some species every vestige of the byssa _ apparatus has disappeared (Solen ensis, etc.), while other forms _ show a partial disappearance. The mucous glands are soa ` scattered over the foot, but more often they are localized in the _ free anterior extremity; while in Lima,Pecten, and Anomia ef charge into a furrow. It has often been argued that the rap 1886. ] Loblogy. l 985 increase and diminution of size observable in the foot must be caused by the presence of aquiferous pores which permit water to i enter into the circulation, but M.

It was situated upon the left side of the animal, in i the midst of the hepatic cæca. The question why the scallop, Pecten, is so abundantly supplied with eyes has often been asked and has never received a satisfactory answer.

EMBRYOLOGY.’ WHY DO CERTAIN Fish Ova Fioat?—In a recent paper, by a Mr. Prince (Ann. and Mag. Nat. History, 1886), his readers are informed that the buoyancy of certain fish ova is not due to the presence of drops of oil in the yolk as supposed by Ryder, or words to that effect. Had my conclusions not been so summa- rily disposed of by one whose information is clearly not very accurate or extensive, the writer would not trouble himself to reconsider the subject of the buoyancy of fish ova. In my Embry- ography of Osseous Fishes (p. 118), I have stated that “ the buoy- ancy of the cod’s egg is undoubtedly due to the diminished specific gravity of the protoplasmic matter of the vitellus, and not to the presence of any oils. In this respect it represents an unique type of the buoyant ovum.” This statement, published in 1884, but written in 1882, is essentially the same as that of Mr. Prince, published in 1886. Comment is unnecessary. There are several types of buoyant ova. These are: (1) Those in which the specific gravity of the yolk is diminished, as in the egg of the cod; (2) those in which large oil-drops in an eccen- tric position aid in causing the eggs to float; (3) those in which a very large oil-drop caused the ovum to float even in fresh water. These three categories are also, in all probability, connected by intermediate kinds; that is, amongst forms of the second series there are some which are buoyant in water with as low a gravity as 1.014, while others are not buoyant in water of less ‘specific gravity than 1.025, while those in which the proportion of oil to plasma is very great, or about as I to 7, are enh? E water with a specific gravity of very nearly 1.000, or in that wh! is fre. As a rule, the buoyant ovum has the oil gathered into a "e drop embedded in the vitellus nearly opposite the germinal a : there seem to be few exceptions to this rule. There are also “ very few species known which have buoyant ova without eat drop, and these are buoyant only in water of rather high Oak - gravity. Furthermore, as a rule, fish ova which are buoyant st not adhesive, but float about near the surface singly; the ea noteworthy exception to this rule is presented by the great pe oe _ egg-ribbons of Lophius. ~ ap Baited by Jonx A. RypeR, Biological Department, Univ. of Penna» Philadel- STS ay EST, = a fend W 1886, ] Embryology. 987 The great majority of species of both fresh and salt water fishes, which have heavy, subsident ova containing oil, have their eggs provided with thick, heavy membranes, which are adherent to each other or to foreign bodies, or to both. Furthermore, their €gg-membranes are usually adhesive, with the oil-drops scattered beneath the surface of the vitellus, or aggregated in a flat, dis- coidal group beneath or alongside of the germinal disk, and not very transparent. The whole egg is also usually more or less colored or granular. The egg-membranes of those species which have buoyant ova are, on the other hand, characteristically thin and delicate, so that it is difficult, if not impossible, to make out the presence of pore canals, while the whole egg is, as a rule, re- markably transparent. ; These characteristics seem to show that the buoyant ovum is a very well-defined and specialized type, which has been developed in the course of the struggle for existence to serve a very useful Purpose in insuring the protection and survival of the embryo dur- ing the hatching period. _ There are fresh-water forms, also, which have buoyant ova, as in the case of Macropodus venustus, in which the proportional vol- ume of the oil-drop is greater than in any other known type. e oil in this case when liberated at once floats at the surface, as does e egg when entire, while the plasma of the germ and vitellus at once sinks. This fact, it seems to me, finally and conclusively Proves that the pelagic or buoyant habit of many fish ova is due to the presence of oil aggregated, as a rule, at the vegetative pole of the vitellus in the form of a single drop. The other conditions are (1) that the egg be free and not adhesive, with a thin mem- brane, and (2) that it be immersed in water having a greater density n 1.014. The one notable exception to the last part of this eneral statement, viz., Macropodus,} it seems to me, serves to show that the presence of oil is very important, and may excep- Bas be the sole cause of the buoyancy of the egg.—/ohn A. er, observing the development of the common mackerel, Scomber |For an “pportanity to study the development of this form, I am indebted to my hi.

On page 373 he says: “ The object of food-yolk, as is well known, is to enable the young to abbre- viate its development by having its food supplied, and being con- sequently able to skip some of its ancestral stages.” Instead of this being the fact, exactly the reverse is true, as has been shown by Balfour, Cunningham and myself—/John A. Ryder. PHYSIOLOGY. Some Nores on RECALCIFICATION oF Human Teera.!—The extent to which human development depends upon the proper utilization of food is such that any fact bearing upon the success of this process becomes of paramount importance. Living in a section of country where diet and drink are unusu- ally deficient in calcific elements, my attention was many years ago called to the analogous condition of the teeth of children in that region, which, as a rule, are characterized by a correspond- -ing deficiency in calcific elements. Rapid and remarkable changes also occur in the condition of the teeth of adults—almost in direct ratio to their changes of en- vironment in this respect. The “ baker’s bread” and other food Products in most general use by the inhabitants of the region near the Gulf of Mexico, and more especially by the inhabitants of cities, are largely divested of calcific elements, while the water used for potable purposes is almost exclusively rain water, which, though a good solvent, contains no mineral elements. The wonderful power of adaptation possessed by our race is Such that people, living in this region for a number of generations, acquire the power of appropriating, from the meager supp'y thus furnished, the necessary elements to produce fairly good teeth ; but the very large number of residents, not natives of this section, whose early life and the life of their ancestors, has been spent in regions where calcific elements were more abundant, and whose Constitutional habit was accustomed to that abundance, are not able to assimilate, out of this meager supply, the requisite propor- tion of limesalts. ey, The function of nutrition being dual in its character—removing effete and worn-out material on the one hand, while supplying the elements to maintain the integrity of the tissues on the other —the calcific elements, which form the inorganic basis of tooth- Substance, and which rendered the teeth hard and firm, are car- ried away, while the supply to rebuild, being deficient in quantity, the corresponding amount is not restored, the teeth in conse- quence soon become decalcified and softened, falling an easy prey to unfavorable conditions. "Read before Sections F and H in joint session, Buffalo Meeting A. A. A. S., oe | 1886, A ek 990 General Notes. [November, The fact of decalcification has long been recognized in the pro- verb concerning mothers: “ For every child a tooth,” not, how- ever, that the material of the mother’s tooth is absolutely taken away to build up those of the child, as was once taught, but that the increased demand for building material not being met with increased supplies sufficient to meet the demands of both mother and child, the teeth of the former suffer the consequences of lack of supplies. The rapid decalcification thus occurring, is not a breaking down of the organiç structure, and, if the material necessary to recalcify, is provided in a form which nature can appropriate, this softening may be prevented, or teeth which are already soft- ened may be rendered hard and durable. - Observing these phenomena—this softening of teeth in persons coming from regions where good teeth are the rule, and the re- calcification following their return to their old homes—led me to investigate the relations between environment and the develop- ment of teeth. A careful observation of these phenomena not only showed the utter fallacy of the old dictum, that the teeth were subject to no changes after maturity, but also showed that there must be a sys- tem of circulation throughout the entire substance of the tooth, making this action of the nutrient function possible during the whole life of the tooth. ; The fact of decalcification and recalcification, and continued nutrient action during life, being established by long observation, suggested the study of the best modes or methods of aiding nature in the work of recalcification. Any possible change from ordinary diet, was found, as 4 rule, entirely inadequate ; the natural suggestion of the direct ad- ministration of the phosphates—the chief inorganic elements 1? tooth substance—also proved entirely unsatisfactory, and led to the recognition of the truth that “nature will not take the ele- ments from any ready-made source, but must elaborate her own pabulum.” E Icification observed in the teeth of those visit- ing favorable regions was zot due to the use of lime in the shape 0 phosphates, and that the difference between the nutrient elements of these same people, whether in the mountains or in the low- lands, lay more largely in the water they drank than in the foo they ate, suggested the administration of aqua calcis ; and on = was followed by results as eminently gratifying as the use of the phosphates had proved unsatisfactory. ee _ A new preparation of lime, in the form of a syrup of Cleef much greater strength than the aqua calcis, and proportionate E _ More prompt in its action and effects, has proved still more st _ fying in its results. i 7 An extended experience of many years has proved that by ti® 1886. | Anthropology. 991 means it is not only possible to restore soft, decalcified teeth of all ages, but to prevent their decalcification, and also to forestall de- fective calcification of children’s teeth, and even to improve the original type; so that we are now able to overcome not only bad environment but even bad heredity also. Running pasi passu with my study and observations on the in- vestigations of the microscopical histologists, the discoveries of McQuillen, S. P. Cutler, Carl Heitzman, Bodecker, Frank Ab- ott, A. H. Thompson and others, have demonstrated the exist- ence of the system of nutrition, which, reasoning æ posteriori, I assumed and announced many years ago. The living fibrillæ radiating through the dentinal tubuli; the Osmotic action between cementum and dentine, and dentine and enamel, and vice versa, the circulating currents through the areas of living matter between the enamel rods and.prisms are, to-day, admitted histological facts, demonstrated by the microscope. he tooth is raised to the dignity of a living organ, with a cir- culating system, carrying pabulum to all its parts to supply the hunger of its needy tissues. _ A knowledge of these facts, and of the best methods of supply- ing material to maintain the integrity of the dental tissues, or o restoring those whose integrity has been impaired, is destined to ave a far more important bearing upon human welfare than any degree of skill in operative or prosthetic oral surgery—/. œR.

It was very much so with stone imple- ments. Not many years agoa man who had a large collection of atrow-heads and such things was called an archeologist. But we now call by that name the men who utilize these things to Spell out the history of human industry and invention.

He had pre- viously (in Vol. 11, pp. 285, 311) advocated a systematic effort of folk-lorists in the same direction, A few definitions are given be- low to indicate the mental drift of the gentlemen interested : “ Folk-lore is anthropology dealing with primitive man ” (Al- fred Nutt). “ Folk-lore is anthropology dealing with the psychological phe- nomena of uncivilized man (meaning unlettered as well as sav- age), and embraces both folk-thought and folk-wont (practice) ” (E. Sidney Hartland, Folk-l. J., 11, 340). “ That portion of anthropology which deals with the psycho- logical phenomena of primitive man” (C. Staniland Wake, Folk-l. J., 1, 345). “Folk-lore is the unwritten learning of the people. Folk-lore is not a science, it is the thing itself. One of the chief objects of the collection and arrangement of the facts of folk-lore is to gen- eralize and philosophize, but the generalizations which we arrive at will not be folk-lore ” (Henry B. Wheatley, Folk-l. J., 11, 347). “ Folk-lore deals primarily with the survival of primitive cus- toms and beliefs among civilized races, and is comparable with, age races. The sanction back of folk-lore is tradition. Folk- lore is the science which treats of the survivals of archaic beliefs and customs in modern ages” (G. L. Gomme, 1. c. 111, 14). “ Folk-lore, ‘ the folk’s learning, all that the folk believe or practice on the authority of inherited tradition, and not on the authority of written records ” (Charlotte S.

Several of the gentlemen have wisely started their study with the two inquiries, who are the folk, and what is lore? Señor Alvarez remarks, “The word folk, German volk, Latin vulgus, Italian volgo, Spanish vulgo, signifies not the whole of humanity, but a portion of the human race, who possess a series of common signs, and are really anony- mous in contradistinction from that other series of men who pos- sess a notable personality.” He would include practically all sav- ages and the untutored herd of civilized society. tion to all that it has added of new embraces, includes much of all the antecedent ages, grades or epochs. e folk-lorists are, there- fore, altogether scientific in collecting the lore of savages en masse, the lore of barbaric and civilized peoples, so far as they are sur- uwals of times not their own. Practically, therefore, what do the folk-lorists wish us to col- lect, and how shall we name and classify our material after it is gathered? Justat this writing we are inclined to use Miss Burne’s modification of Mr. Gomme’s scheme. For the filing of tales the folk-lore society has adopted a scheme, with printed headings, as follows: 1.

The English wristguard is worn on the inner and lower part of the arm ; the Japanese need none, as they fling the bow half round at the mo- ment of release, The English archer grasps his bow in the mid- dle; the Japanese near its lower third. In the English method the string is drawn with the tips of the first three fingers; in the Japanese the string is drawn back by the bent thumb. The methods of release characterized are as follows: 1. Primary.—The nock of the arrow is grasped between the end of the straightened thumb and the first and second joints of the bent forefinger. It is practiced by children universally, and by the Ainos, Demeraras, Utes, Navajos, Chippewas, Micmacs, Pe- nobscots. 2. Secondary—The nock of the arrow is grasped with the straightened thumb and bent forefinger, while the ends of the sec- ond and third fingers are brought to bear on the string to assist in drawing. It is practiced by Zufiis, Chippewas of Wisconsin, Ottowas. 3. Tertiary —In this release the forefinger, instead of being bent, is nearly straight, with its tip, as well as the tips of the second and third fingers, pressing or pulling on the string, the thumb, as in the primary and secondary release, active in assisting in pinch- ing the arrow and pulling it back. It is practiced by Sioux, Arapa- hos, Cheyennes, Assiniboins, Comanches, Crows, Blackfeet, Nava- jos, Siamese, Great Andamanese. : 4. Mediterranean—tThe string is drawn back with the tips of the first, second and third fingers, the balls of the fingers clinging to the string, with the terminal joints of the fingers slightly flexed. The arrow is lightly held between the first and second fingers, the thumb straight and inactive. Practiced by nations around the Mediterranean by modern archers, Flemish (using first and second finger only), Eskimos, Little Andamanese. 5. Mongolian —In this release the string is drawn by the flexed thumb bent over the string, the end of the forefinger assisting ' holding the thumb in position. The thumb is protected by a _ guard of some kind..

Horatio Hale before Section H of the American Asso- ciation at Buffalo was upon the origin of languages and the an- l tiquity of speaking man. It contains views so original and novel that it is eminently proper to present a condensed scheme of the i argument. 1. Among the puzzling questions in anthropology which we are bound to notice are these two: When did linguistic stocks : originate? When did man acquire the faculty of speech? It will i be seen that the origin of languages and the origin of language are two very different questions. Mr. Hale, rejecting the old theories which rely upon time, the dispersion of a monosyllabic parent stock, the dispersion of speech- Jess man and the origination of languages in different centers, avers that the origin of linguistic stocks is to be found in what may be called the language-making instincts of very young chil- dren. To insure the creation of a speech which shall be the par- ent of a new linguistic stock, all that is needed is that two or more young children should be placed by themselves in a condi- tion where they will be entirely, or in a large degree, free from the presence and influence of their elders, and that they should Continue in this condition long enough to grow up, to form a household, and to have descendants to whom they can communi- cate their new speech. This theory is elaborated with great care and the multiplicity of stocks in California made by a camping- ground of the argument. The second part of the argument is also accompanied with the ı revival of startling doctrines, namely, that while the antiquity of man is incalculable the speaking man is of recent origin, having occupied this planet at most not over ten thousand years. “If we are willing to give the name of man to a half brutish being, incapable of speech, we must allow to this being an existence of vast and as yet undefined duration, shared with the mammoth, the woolly rhinoceros, and other extinct animals. But if we term the beings of that race the precursors of man, and restrict the name of men to the members of the speaking race that followed them, then the first appearance of man, properly so styled, must be dated at about six thousand or ten thousand years ago. And this man who thus appeared was not a being of feeble powers, a dull-witted savage. He possessed and manifested from the first intellectual faculties—intellectual faculties of the highest order— Such as none of his descendants have surpassed. His speech, we _ May be sure, was not a mere mumble of disjointed. sounds ; it _ Was a full, expressive, well-organized speech, complete in all its | . The first men spoke because they possessed along with * the vocal organs the cerebral faculty of speech ; “ that faculty was | instinct of the mind, as irresistible as any other instinct.” eS aaa 998 Scientific News. [ November, SCIENTIFIC NEWS? — The French Association for the Advancement of Science held its session this year at Nancy. Thirty-two savans contributed papers upon engineering and mathematics, forty-four upon physics and chemistry, fifty-eight upon the natural sciences, and fifty-nine on economics, some contributing several papers. The Revue Scientifique (Aug. 14) prints in full the address of the president, M. Friedel, upon the progress of chemistry and mineralogy ; that of M. E. Collignon, secretary, upon the history of the association during the year; that of M. A. Volland, mayor of Nancy, and that of M. E. Galante, treasurer, upon the finances of the association. From the first of these discourses it appears that spinel, corun- dum, and rubies have been manufactured artificially, and that the false rubies are not infrequent in the market. The last meeting, held at Grenoble, received a total of 342 communications, 100 0 which were upon the natural sciences. Fourteen members were lost by death during the year, including MM. Bouquet, Bouley, Jamin, Robin and Dechambre. The number of associates is kept up to three thousand eight hundred. ‘ Among the papers read in the natural history section were those of M. Cartailhac, on sepulchres of the stone age, etc. ; of M. Chatin, on the flora of Paris and Dauphiné; of F. Lataste, on the tion to the prevalence of burial after decomposition of the on parts.

THE SCALLOP AND ITS FISHERY, BY ERNEST INGERSOLL. } Tioucs it had long previously been enjoyed by the shore- towns in New England, the introduction of the scallop as an edible into the New York markets is as recent as 1858 or ’59. Now the annual product of the fishery, which is restricted in area and subject to much variation, amounts to something like 75,000 gallons in all, worth from twenty-five to thirty thousand dollars at first cost; and New York receives and dispenses about three- fourths, ) The species of scallop in question is Pecten irradians, which is common in suitable places all along our coast. Besides this there are half a dozen other varieties, living at more or less depths, in _ the western Atlantic, one of which, the great Pecten tenuicostatus of the coast of Maine and the Bay ot Fundy, was formerly highly ` = Valued by the people of that region, but now is too scarce to ap- _ Pear on the tables of even “the rich” except at rare intervals, 1 The fishery and methods of preparation for market of our scal- lops present several features of general interest, and I believe that _ i my study of the matter, a few years ago, as an agent of the | Census Bureau, I was able to learn some new and suggestive = Particulars as to the habits of the mollusk.

Long Island sound, New York bay, Sandy Hook and much of the Jersey shore, have been so thoroughly depopulated that any fishery for scallops there has been abandoned. Occa- sionally a supply appears at this or that point, but uncertainly and temporarily. I was told, for example, by the oyster-planters on the north shore of Long Island, that scallops were tolerably plentiful there (particularly at Northport) once in five years. Such a statement is puzzling, and leads to a study of the habits of the scallop in search of an explanation. The proper home of this species (P. irradians) seems to be in fairly deep water on a firm bottom—either sand or tough mud ; yet in many localities grassy beds (2. e., eel-grass—Zostera) are resorted to by it, especially when young. The general habits and behavior of our American scallops, such as living in com- panies or ‘“schools,” moving about and darting to the surface of the water by a quick opening and shutting of the shells, to sink down again along an inclined plane forward, are familiar to all readers of natural histories, and closely similar to those of the European “ St. Jacob’s shells.” _ The spawn of our scallop is thrown out in early summer, and so much of it as becomes fertilized and is able, “catches” or “sets” on stones, sea-weeds and other firm supports, from the sheltered tide-pools down toaconsiderable depth. By the middle of July this “ seed ” is about as large as the head of a lead pencil, and it does not drop from its support for two weeks or more. The growth is so very rapid that the young scallops have attained about half their size by the time cold weather checks their ad- - vancement. In November the young scallops, spawned the previous June, will be found in great numbers all along the clean shores of . ragansett bay from an inch to an inch and a half in diameter, an i ; i t moving about very actively. Where eel-grass grows 10 ane g quantities, however, the young keep among it, clinging te stalks until by their weight they bend them down to the bottom or break them off, and are swept away with the gras goes adrift in the fall. Should such a tenanted raft of sea- = -drift into a bay and rest there, as frequently O s when it weed where 1886. } The Scallop and its Fishery. 1003 Great numbers, however, forsake the protection of the eel-grass, when old enough, and go “dancing” about the neighborhood till they hit upon the right kind of bottom, when they come to anchor, and stay there unless driven away by extraordinary winter storms. Under such an accident ‘thousands of bushels may sometimes be driven upon the beach, where all are pretty sure to die by freezing. Referring to this point a Sag Harbor man told me that if possible, when driven before a storm, they will work to windward, and he assured me that he had seen them swimming in schools ten feet deep. These movements are all within narrow limits, however, for the restricted bounds of the fishing-grounds are pretty nearly the same from year to year, though often it is impossible to see why the scallops should not extend their range. The young are far more active and swift than the older mollusks. Late in the fall, however, there is re- Ported to be a regular migration of adult scallops toward the shore, whereupon the fishing begins; but this statement is not well substantiated, I fear. The size of the young scallops is little increased during the colder months, but in the spring a new period of speedy growth begins and maturity is said to be reached within a year. At any rate these mollusks will produce spawn in the June following their birth, and are ready for market the subsequent autumn. The rapidity with which they enlarge their bulk, but more espe- cially their fatness, or proportion of flesh to shell, is remarkable. Thus a bushel of these mollusks will yield only about two quarts of “meats ” in October, whereas a bushel from the same locality at Christmas will turn out a gallon. ; The fishermen believe that scallops never spawn but once, and die before they reach the age of three years. Iam not at all sure this is a fact to the extent alleged, but if so it presents a case Where the generations follow one another so closely that there are never two ranks or generations in condition to reproduce at Once (except in rare individual instances), since all, or nearly all, i : of the old ones die before the young become mature enough to Spawn.

Similarly an unusual attack by natural enemies, or excessive dredging by men, might in one season extirpate the scallops of a whole bed or bay. To its active powers of movement and its migratory habits, the scallop must mainly trust for preservation as a race, and to the fortuitous drifting in of young upon rafts of sea-weed most depleted localities chiefly look for rehabilitation. Whatever the explanation, the supply has certainly decreased 4 along our coast during the past thirty years, even though at cer- tain points—as in the Peconics—there seems no diminution. The huge, smooth-shelled Pecten tenuicostatus of the North, as big as a fruit plate, which formerly abounded on the coast of Maine, has now become so rare as to be a prize in the cabinet of the conchol- ogist rather than an edible commodity—a result unquestionably due to over-greedy catching, and an effective reply to those men who told me that they thought the more the scallop beds were raked the more plentiful the mollusks became. Long Island sound no longer affords profitable fishing, and the depletion there is attributed by the local fishermen to the fact that in culling their dredge-loads the little ones were not thrown back. The same story belongs to New York bay and much of the New Jersey coast. The irregularity in respect to plenitude, and also of the size and fatness of these mollusks in the three localities—Buz- zard’s bay, Cowesett bay (R. I.) and Long Island—where they are still regularly taken, is steadily complained of. ' Scallops are caught by hand-dredging from small sail-boats. The dredges are about thirty inches in width, have a scraper-blade upon the bottom, and in favorable weather several may be thrown over from each boat. In shoal water an iron-framed dip-net 1s sometimes used on calm days. It is pretty hard work, and en- tails exposure to very severe weather. _ The only edible part of the scallop is the squarish mass of muscle (the adductor) which holds the shells together, and this part 1s . skillfully cut out by “ openers,” who have their houses at the land- ing places where the dredgers take their cargoes to be sold. It is the buyer, not the dredger, who “opens” or “cuts out” the meat and prepares it for market. In some places men alone are ployed in this work—at others women and girls for the most they will earn from eighty cents to $1.25 4 day. The 1886 ] The Scallop and its Fishery. 1005 work is performed with great dexterity. The motions of an ex- pert opener are but three after the scallop is in hand. The bivalve is taken in the left hand, palm up, with the hinges of the scal- lop toward the opener’s body. The knife—a simple piece of steel ground sharp, and with one end stuck in a wooden handle —is inserted in the opening of the shell furthest from the breast. The upper “eye” is severed through by this movement. A flirt at the same moment throws off the upper shell. The second mo- tion cuts the lower fastenings of the eye to the upper shell and takes the soft and useless rim off. The last motion pitches the shell into one barrel and the soft and slimy rim into another, while the eye is thrown into a basin of yellow stoneware holding agallon. They are then poured from the basin into a large col- lander, thoroughly washed, placed in clean boxes and shipped to New York and Brooklyn. As little fresh water or ice is placed in contact with the “meats” as possible, as it is thought detrimental to their firmness and flavor. As this is altogether a winter operation, the help of ice in transportation is not usually needed. There is, or ought to be, no waste in the scallop fishery. On Long Island the refuse is taken by the farmers as manure. These sea-faring agriculturists have always been accustomed to replen- ish their half-exhausted lands with the scrapings of the beach and with the menhaden and other seine-fish which could be caught plentifully enough for the purpose in the offing—much to the disgust of every stranger who found himself to leeward of their fields. This demand failing, there is always sale for the refuse to the regular fertilizer-factories scattered along the shore. The shells are preferred above all others by the oyster-planters as “stools” or “cultch” to spread upon their deep-water plant- 5 i i ” $ ing beds as objects upon which the oyster-spawn may “ set ” and grow. This wise preference is due to the fragility of the scallop- shell, permitting it to break into pieces under the strain of a growing cluster of oysters, each one of which will be benefited by the separation, which frees it from the crowding of its fellows and gives it room to expand by itself into comely and valuable rotundity, instead of remaining a strap-shaped distorted member of a coalescent group. All their shells, therefore, can easily be os Sold by the openers to the oystermen at from three to five cents a bushel. ee 1006 Super-Metamorphism and Vulcanism. (December, The scallop fishery is of small moment in the United States be- side the production for market of oysters and clams, and the statistics (for which I am chiefly responsible) are meager, and not later than 1881, though I doubt whether this year’s figures would show much difference from the status of five years ago. Briefly summarized, these show that about 250 men (and for a short season at New Suffolk, Long Island, about 470 women and children, according to Fred. Mather), are engaged in either catch- ing or preparing scallops, using boats and apparatus worth per- haps $20,000. The total product is from 70,000 to 75,000 gallons of the edible part, as marketed, worth at first hand from $25,000 to $30,000. About one-half of this comes from Peconic bay, and more than half the remainder from Greenwich, Long Island. . id ity tae? oe SUPER-METAMORPHISM AND VULCANISM:! _ BY THEO. B.

We can not detect the direct evidence of such previous condition in the thoroughly ` fused masses, but there is in many cases no real proof to the con- trary, to say the least, Now, if these simple postulates be admit- ted, how can we consistently deny the possibility—nay, the prob- ability—of the occurrence of all degrees of metamorphism from the simple baking to the melting effects? Geologists have com- monly supposed that a well-defined zone of metamorphism has existed over the earth involving just so much of the sub-stratum of the crust, never passing the boundary set by the lowest mem- ber of the Paleozoic series. This view does not comport with the very gradual transitions observable in all other natural pro- ducts, nor can it be reconciled with the numerous facts which go to prove that the great geologic agents of the past are active now as then, in kind if not in degree. : _ Really, then, it would be marvelous if extended study of ge 3 paca history should not reveal fluctuations of the metamorphic -~ zone, above and below the arbitrary stratigraphic boundary ade pted in the early days of our young science. ra iieri pn iboa before Section E, A.

W. Colorado) become involved in the zone of metamorphism; that is to say, super-metamorphism has oc- curred. All along the Rocky Mountain chain to the north- ward the Silurian beds are recognizable, although I have seen them very much baked in portions of Northwestern Wyoming. The same succession of strata from top to bottom of the Palzo- zoic is discernible southward, as a rule, until we strike the great loop of the continental divide in the San Juan mining region, where the sedimentary formations skirt the base of the Quartzite mountains of Hayden’s survey. Here the Carboniferous and the underlying Devonian are well represented, and insignificant remnants of supposed Silurian strata occur zm situ. In some cases these last-mentioned rocks shade down gradually from the un- modified sédiments to the completely metamorphosed layers, and occasionally the Devonian limestone is so intimately connected with the subjacent granite as to form a continuous block of the two rocks welded together into one mass. Beneath the granites is a vast formation of quartzite, and the whole section studied by itself and in connection with the succession of strata in the adjoining country, seems to me wholly inexplicable upon any other theory than that of super-metamorphism, involving a con- siderable thickness of the early Palaeozoic beds, including nearly all of the Silurian formation. This idea, although worked out independently by myself, was, I find, entertained some years ago by Dr. Endlich, who passed rapidly over a part of the region in 1874. The importance of the fact, if such it be, of this super-metamorphism appears very evi- dent when we come to study the history of vulcanism in Colo- rado and Wyoming. From observations by the writer in the lat- ter area, in 1873, there seems no doubt that very similar condi- tions have existed in that great focus of eruption, although the results have been there much obscured by the lava flows and less disclosed by subsequent erosion. Referring to the preceding remarks on super-metamorphism, we may understand how, with a crust offering excessive resistance, | othe igneous fusion may be longer continued than in the case of a _ Volcanic eruption like those of the early Tertiary in the West or the Hawaiian initial outflows, all of the andesitic type. Von Richthofen’s series, as exemplified in the order of succession of 1008 Super-Metamorphism and Vulcanism. [December, the lavas of the Western United Statés is, in the rough; of such wide application that we must expect to discover more thana mere accidental cause. The occurrence of onlyone type of lava, as andesite, trachyte, rhyolite, or. basalt, may be readily explained as due to the overcoming of the resistance to outflow at one or other stage of the process of fusion. So, in certain wide areas, it might be possible for all of Richthofen’s types to be ejected from as many distinct orographic centers. But in Wyoming and Colorado two great districts have the old volcanic vents so re- lated to each other, in the several flows, that one can not avoid the conclusion that each field ‘has been the seat of one long-con- tinued period of activity marked by successive epochs of erup- tion. Thirteen years of study in these regions have revealed many facts bearing upon these questions. Having elsewhere out- lined a plausible theory of vulcanism,! based upon these and gen- eral information gleaned from ‘the West Indies in merely travers- ing that region, together with the published accounts of leading authorities, I shall not here attempt a discussion of it, but confine myself to a simple statement of its main points. In brief, then, it seems evident that the earliest volcanic out- flows came out through lines of least resistance in the axes of folds in the strata. In cases where these lines coincide with the major folds and the lines of maximum tension, the outflow will be andesitic or basaltic, č. e., basic. If the tension be not suffi- cient to overcome the resistance, more acidic material will be formed at the top of the magma, under the folds, and this may burst forth as trachyte, or finally as rhyolite, provided that the resistance is not sooner overcome. Basalt comes last as the deep- seated, heavier portion of the magma, and in some cases this fol- lows andesite without the intervening trachyte and rhyolite. In the San Juan mining region and in the Yellowstone Park area, the necessary conditions for the successive ejections have been brought about by a somewhat complicated series of foldings, -eross-foldings and faults, accompanied by an elastic crust of sili- a ceous material. The subject is one which can be studied in these a regions to great advantage, but we are only beginning to under- stand how simple is the problem which nature has solved with much variety of detail to suit changirig conditions of environment.

Not only in the same geological horizon will he find striking variations in the abundance in which the fossils occur, as he passes from layer to layer of contiguous and often of the same beds, but he soon discovers the important fact that localities are distinguished by peculiar fossils, that a limited range circum- Scribes the lateral as well as the vertical diffusion of a species, as far as regards numerical concentration, and that again points or limited areas present, in overflowing numbers, representatives of an organism which, generally occurring throughout a wide geo- graphical range, are at these points illustrated in crowded and exuberant colonies.

A great deal of instructive and careful study has been expended in recent years, since the advance of research has made natural- ists better acquainted with the oscillatory character of faunal populations, upon the perplexing question of the contemporaneity and succession of fossil faunas, and Barrande, Etheridge, Hall, Hull and Gosselet abroad, and Williams, Walcott, Call, Clarke and Matthews at home, have pointed out some of the details of their results in this investigation, and have already familiarized the scientific world with the important conception that varietal faunas or modification of a central or controlling animal facies, or even sharply contrasted zodlogical aggregations of species may belong to the same epoch and be laid down in the neighborhood of each other on the same oceanic or lake flooring. Our intention here was not to discuss the variations of specific forms in the fossil-bearing rocks as throwing light upon the syn- chronous existence of different faunas, their succession, retreat, reappearance and fusion. It is undoubted that these assumptions explain and are indeed the chief explanations to be offered for the varying character of near-lying fossil groups; but we wish to urge upon the consideration of palzontologists the necessity of allowing—as far as regards the instances of fossil distribution cited above, viz., the greater or less prevalence at near horizons or beds or along the horizontal extension of the same bed of the same fauna or species—for those irregularities of production of life, which cause in our present seas different years to become dis- af : tinguished for a phenomenal abundance of certain forms, as _ Others to claim a distinction for the abnormal decrease or disap- pearance of the same forms over the same geographical area. = Thus a given spot on a coast line, always yielding a particular __ Species, may in one season become the abode of numbers of these T e i | Amer, Mus.

IOft same animals out of all proportion to its ordinary census of occu- pation, and in another season pass, by an abrupt change or per- haps through a series of less violent alternations, to a condition of comparative or actual denudation of these residents. The work of the Fish Commission has made us familiar with facts of much wider import, when large sections of the oceanic basin have become depopulated. This latter case appears to be catas- trophic in its causes, but comes within the scope of our sugges- tion as to the fluctuating fertility of a species. And the fact be- comes sometimes apparent that in a restricted region command- ing amore or less fixed supply of nourishment the size of the animals will increase in the years of decreased fertility, and cor- respondingly diminish in the seasons of enhanced productivity, a relation not unnatural. To what extent we may parallelize these two classes of facts, the one dealing with the changing abundance of fossil shells or remains, either vertically or horizontally distributed in beds of the same age, and the other exhibiting the varying numbers, in Separated seasons, of contemporaneous animals along our sea- | boards, or in our fresh-water lakes, or even, so far as we can de- termine, in the pelagic areas, is not at first, or in all cases equally easy to determine. But it is possible to review some considera- tions bearing upon the general question. _ The observations which may be adduced as bearing on this question are necessarily widely scattered, and when found are for the most part concerned with those forms of life which subserve Some industrial or economic uses, or with those in close relation with the former, as, for instance, the recorded irruptions of star- fishes (Asterias forbesit) and “ drills” (Urosalpinx cinerea) in dif- ferent years upon our oyster beds. In classifying, however, the efficient causes which effect these variations of animal populous- ness, without entrenching upon ground more or less speculative, we may say that the changing abundance of animal forms in different years or localities arises mainly from: Ist. Opportunity for or difficulty in obtaining fecundation. 2d. Constitution, rate of growth, habits, etc., of organism. 3d. Character of habitat in relation to bottom. ; 4th. Phenomenal influences, as cataclysms, poisoned or heated waters, storms, destruction by enemies. I. Opportunity for or difficulty in obtaining fecundation—That X IOÏ2 Zoic Maxima, or Periods of [ December, this has an important influence in securing a great or small representation of the marine animals in modern seas is un- questioned, though it is always, of course, a variable function of the more or less rapid-and safe methods nature uses for their multiplication. Dr. Brooks says :! “ The most critical time in the life of the American oyster is undoubtedly the time when the egg is discharged into the water to be fertilized, for the chance that each egg which floats out into the ocean to shift for itself will immediately meet with a male cell, is very slight, and it is essential that the egg should be fertilized very quickly, for the unfertilized egg is destroyed by the sea water in a very short time.” Tryon has suggested that the swimming species of Cephalo- poda may experience some difficulty in effecting sexual union,” and the observations of Steenstrup upon the many different ways adopted in this group of Mollusca for fertilization, justify the in- ference that under unfavorable circumstances individuals of the same group may not encounter each other, and the chances for the fruitage of the same genera be diminished in exact ratio to the opposite plan pursued by its congeners for their fecundation. With some of the gastropods sexual union is effected directly, and no danger is incurred from the exigencies of the unprotected female ovum searching for the spermatic vesicles in the water. This establishes a safeguard which favors the multiplication of those prosobranchiates which possess it, but in other groupe (Trochus, Scutibranchs, Cyclobranchs) the male elements are dis- charged into the water, and are then taken into the uterus. This introduces a risk which must increase or lessen according to the presence or absence of predatory fishes who devour the spat, the favorable stillness of the water or its temperature, or chemical condition, which if abnormal would destroy the germs. ?

The orders of Cladocera, Copepoda and Ostracoda will, in this respect, be favorably placed in comparison with other crustacean groups, as in these tribes fertilization of the female lasts during her lifetime, or at least a season, and in some cases the young females are born fertilized from the impregnated mother. Thus favorable conditions with these groups gain a predominating in-' fluence, as they fortify and assist an already preéxistent advan- tageous arrangement for security of fecundation. Amongst fishes advantage will be given to those whose spawn- ing season is most extended, as with cod, with which, according to the observations of Professor Sars, it extends over nine con- secutive months, “a period éxceeding that required by any other Species of which we have any knowledge.”! These are not only more likely, with equal vitality, to produce a larger number of in- dividuals, but they are absolutely favored, by the greater extension of time, to escape variable inimical circumstances, which latter, being limited in duration, might, if coincident with the shorter period of other fishes, greatly impair the prospects of successful fecundation. The longer period of the cod renders its partial or entire escape from such disasters more probable. The spawning season for an individual of shad, salmon, or white fish is only a few days. But the likelihood of impregnation seems to be dimin- ished on spawning grounds where strong currents are found, or during storms, as imense numbers of the eggs are driven on the shores, or are so diffused and distributed as not to meet the milt-of the male, and as the egg of the cod quickly loses its Vitality, great numbers perish. . Under very favorable circum- Stances such conditions for impregnation might prevail as would result in an enormous excess of individuals produced, whilst an Opposite state of affairs would reduce the production to a mini- mum. Again, an insufficient supply of males would greatly mod- ify the results of fecundation, as the extraordinary fertility in eggs of the female amongst fish necessitates the presence of sev- eral males to accomplish their fertilization. Eggs of fish which are of such a gravity as not to rise to the surface, unlike those of the cod and mackerel, come less in contact with the destructive R Bull. U. S. Fish Commission, Part v. 1014 | | Zoic Maxima, or Periods of [ December, agencies of the surface, and increase their likelihood of fecunda- tion by the longer possible period thus secured for a greater number, Such fish as spawn in rivers or in the later seasons, as early summer, may be in some instances, or most, more likely to per- petuate a greater number of offspring than their congeners whose eggs in the ocean are exposed to greater risks of destruction or at seasons when storms are prevalent, though this consideration is again modified by the possible presence in either case of more numerous enemies. Ti. Constitution, rate of growth, habits, etc., of an organism — It is obvious that conditions favorable for the preservation and maturization of individuals will prevail when these conditions harmonize with the habit and life-history of the organism, and that the reverse will ensue when they do not, and other things being equal we may expect those species to predominate at a locality whose habits, life-history, etc., are either best adapted to the conditions of that locality over its competitors, or are of such a character as to withstand conditions which, generally unfavora- ble to all forms of life, are met by it with better safeguards and greater resistance, Under unfavorable conditions the longer time in which the young of a marine shell are free before attachment, the less chance for a survival of a great number, and at such a time a selection would be effected in favor of those species whose spat most quickly came to rest, and these would subsequently become phenomenally frequent. ' \gain, the power of an organism to endure change of temper ature, as compared with others less able to survive variation in this respect, obviously works in its favor, and may lead to go apparent excess of individuals. As Semper says,’ “a small fali -in temperature may be as injurious to one animal as a great fall _ to another, while a third species may be wholly unaffected by either.” Mdébius has designated animals under this regard as _ eurythermal and stenothermal, as they are qualified to endure , : _ reat or small variations of temperature. This will also have ” _ important influence on size, as Möbius has shown that the sa species of mollusk living on the coast of Greenland or in the Bal- tic was in the former case large, in the latter dwarfed, and he at- ! tae eg S 2 hry ot hd be ea ng ee 4 1886.] Numerical variations in Animals. 1015 tributed it to the variable temperature in the latter locality. Rate of growth as it is rapid or slow, continuous or periodic, will affect the numerical display of a species. Thus Pecten irradians grows very quickly, stops in winter, beginning again when the scallops are one year old, and on the whole this irregularity may be re- garded as tending to diminish numbers. Power of locomotion again assists its possessors to escape from unfavorable surround- ings or from enemies. Swarming or migratory habits, as with lobsters, affect the numerical proportion of the species at a given point in certain seasons, but probably has little influence on the fertility or abundance of individuals. Those animals, as crusta- ceans, which cast their integuments, are exposed to accidents during their exposed period, and should they then be subjected to especially destructive influences would suffer great numerical depletion. III. Character of habitat in relation to bottom, temperature, depth, isolation, salinity and supply of food—The overwhelming importance of these very variable factors upon the numerical ex- hibit of a species is most evident, and has, from many points of view, been emphasized by naturalists. Thus the nature of the bottom exercises a predisposing selective influence upon mollus- cous distribution. It is well known that oysters are killed in the mud, that the round clam affects sandy and muddy shores, the edible muscle flourishes in a variety of positions and surround- ings, that the Purpura loves rocky headlands, and so on indefi- nitely, Thc temperature of the water exercises an accelerating or retarding influence upon the growth and spawning of both shells and crustaceans according to their nature in this respect, and the increase or decrease of heat. In the matter of living at different depths, animals vary extremely, and the sudden settling of a shore or even rapid secular change would tend to destroy the classes of shallow-water loving organisms. Isolation permits close interbreeding, subjects the species to more uniform condi- tions, and if it diminishes the volume of water seriously modifies -the size, as shown with Lymnza by Semper and Hilger, while of course it induces peculiarities of local development. Salinity varies in sea water and enclosed areas of the ocean, and distinctly modifies the abundance of animal life. The character of the — Supply of food and its abundance is an obvious element of great importance in the production of sea animals. 1010, Zoic Maxima, or Periods of Numerical, etc. { December, LV. Phenomenal influences, as cataclysms, poisoned or heated waters, storms, shocks, destruction by enemies —It is enough to mention these to suggest their frequent occurrence. But the effect of these in geological time has been, doubtless in some case, to produce deposits of animal forms in sudden abundance, as when a fauna by their action has almost simultaneously dis- appeared. Thus Dr. Newberry has suggested that the fish beds of Illinois afford evidence of a wholesale destruction of fish life, possibly through submarine explosion, diffusion of poisoned vapors, etc., while the phenomenal disappearance of animal life from the Atlantic, as shown by the observations of the Fish Commission in 1881, is a modern instance of a widely extended ‘catastrophic obliteration of animal forms. Zoic Maxima.—lt is evident that if all the above conditions were favorably conjoined for some reasons, in accordance with the needs of any special organism or any group of organisms, | that these would attain probably an unusual fertility, and that if passing such a climax as this the succeeding years would de- velop conditions in the same way, as strikingly unfavorable, we would have in the marine deposits, accumulated during these years, two contrasted beds of respectively rich and barren con- tents connected or graded into each other by intervening beds o diminishing productivity in shell remains. But if after a period of phenomenal activity and success in the production of" forms . such as instanced, a disaster, such as those we have suggested under the fourth heading, took place, then we would have a bed gradually reached through lower beds of increasing numer ical strength until it crowned the series as a climacteric to be suc- ceeded by later layers quite devoid of animal remains. _ These periods, when all the conditions are most favorable for animal multiplication, we designate as Zoic Maxima; and as _ they are in accordance with the requirements of the greatest , number of specific forms we call them Pan-zoic Maxima ; he oe they are so combined as to exert a selective influence, permitting : __ the preponderance of one or a few species, or directly contribu- _ ting to the propagation of this one species both in numbers an in size, we call them Sol-zoic Maxima. _It is certainly true and known that such Zoic Maxima, both in their general and restricted manifestations, are known in our ntemporaneous faunas.

W. PUTNAM. CAN truly say a new chapter has been added to our archzo- logical work in the valley of the Little Miami. First, you must know that our camp is pitched by the side of the great pile of earth we turned over in our explorations of the group of altar mounds on the land of Mr. Michael Turner. We have been ` working, with occasional necessary intermissions, on this and the adjoining farm of Mr. Benjamin Marriott for the past five years, and this is the place where we have discovered-so much of aig within the great earthwork of which the following is a sketch A hill through which two danas. thirty feet deep, had been cut, separated the hill into three parts. Around the central por- tion a wall of earth had been raised, making a perfect circle 550 feet in diameter. In this inclosure was a large mound, and near ita small one. These mounds proved of great interest, particu- larly the large one, with its stone wall four feet high, surrounding an altar of burnt clay. We found several human skeletons in the clay outside of the stone wall and two others on the wall, with various objects made of copper, shell and stone. The earth taken from the ditches was used to make the graded way from the top ` of the hill to the level land below. This graded way connects With an embankment of earth, somewhat oval in shape and 1500 feet in its greatest diameter, in which are two openings. Oppo- _ Site the northern opening is an earth circle 300 feet in diameter, = and in this isa small mound which we have not yet explored. Opposite the eastern opening is a mound nine feet high. It was -On this mound that we began our work at this place five years ago. At the foot of the graded way is a small circle inclosing a burial mound. North of this circle were two. other burial = Mounds, and east of it was the great group of altar mounds,- around each of which was a wall of stones four feet high, built below the surrounding level of the field. These mounds con- tained from one to seven altars, formed of clay, on which fierce : various kinds, particularly of copper, the 60,000 pearls, sheli- ds and other objects, also = wonderful little figures of terra $ hiies T XH. 1018 The Peabody Museum's Explorations in Ohio. [December, cotta representing men and women. All these objects had been thrown into the fires upon the altars, evidently as sacrifices or burnt offerings during an important ceremony. The thirty-seven pits with the singular tubes or “ flues” connected with them; the concrete layer of gravel and iron over them; the singular struc- ture of the great mound, a hundred feet in diameter and twenty feet high; the great pit containing the many skulls, some of which had holes drilled in them, arranged around two skeletons placed in ashes, all serve to show that connected with this group , of mounds were extensive ceremonies of the deepest import to the people. - These extensive earthworks, made on such an elaborate scale, and containing evidence of the wealth of the builders as well as of the ceremonial character of the works themselves, necessarily lead to the conclusion that there must have been a large number of people connected with their construction. The beautiful loca- tion of this group of earthworks on the level second terrace which extends for miles in the fertile valley, and is surrounded by hills from which flow never-failing springs, indicate that in this region there must have been a large population; yet the few human remains which we found in the mounds within and with- out the encircling wall are not sufficient to meet the require- ments. Such remains were probably those of distinguished per- sons, buried with special honors ; but where were the other dead? i Then the many altars, or basins of burned clay, which evidently had been used over and over again, and were, with two excep tions, empty when the mounds were erected over them, are indi- cations of cremation, and yet where were the burnt human re- mains? Cremation in open fires will, necessarily, leave many fragments of calcined bones with the ashes, unless such remains ~ are burnt over and over again, and special pains taken to reduce all to ashes, and yet we had found, in a niche of the stone wall ~ about the large altar mound, the burnt bones and ashes of but = One individual. If these altars were the places where cremation took place, what then had become of the remains? These were questions which Dr. Metz and myself often asked of each other, and we felt confident that somewhere near by there must be 4 general burial place for the common dead, and many a hunt was 3 for surface indications. On the north and south sides of ‘urner’s barn, and west of the large circle, are two scarcely am 1886. | The Peabody Museums Explorations in Ohio. IOIQ perceptible ridges, similar to other slight irregularities here and there over the field. Owing to the cultivating of this place for many years and to the tramping of cattle in the barnyard, these ridges have been more or less worn down, and a few water-worn stones have been exposed on the surface. These were first no- ticed by Dr. Metz about a year ago. As soon as our camp was pitched we took a look at these water-worn stones. They were fragments of limestone filled with fossils of the Silurian age lying ona deposit of gravel over which, long ago, had flowed the waters of the Little Miami. What more could these stones have said, had they been endowed with speech, than that which was evident to our eyes: “ We were long ago brought here by men.” Here, then, was something more to be revealed in con- nection with the history of these great earthworks of an ancient race, and here we would dig a trench on the morrow. We started Our trench sixty feet west from the wall of the circle, and well outside of the slightly elevated portion, which, we were afterward told by Mr. Snyder who remembers the place fifty years ago, Was formerly much more marked, and had the appearance of a long low mound. Digging down to the hard pan, we carried our trench westward for about ten feet, when we came to three large _ Water-worn stones regularly arranged, side by side, in the gravel hard pan. It is necessary to fully understand the character of the earth in which we were working in order to appreciate the labors of the ancient people at this place, and I may well add our own in Making these researches. First, the surface consists of a few inches of dark soil overlying from eight to ten inches of clay. Under this clay is a layer of coarse gravel containing many peb- bles, some of considerable size, but all colored and firmly ce- mented by an amount of iron which, from some natural cause, is far in excess of that in the gravel all about. This iron-cemented §tavel forms an irregular layer of from one to four feet in depth, : _ and under it is a loose, uncolored gravel mixed with sand which, _ Judging from a pit near by, is certainly thirty feet in depth, and Probably much more. It may be that this is part of the great terminal glacial moraine which Professor Wright has been tracing across the State of Ohio. In this iron gravel the stones we found | _ Were imbedded. On cleaning off these stones we found that there were others at right angles to them, and soon we made out 1020 The Peabody Museum's Explorations in Ohio, [ December, that we had at last discovered a grave. Would it prove to have any connection with the people who built the earthworks and the altar mounds? Our hopes were great, and they were soon to be Fealized as far as one grave could tell its story. On carefully removing the earth from the eastern end of the grave, close to the stone, we discovered the toe bones of a human skeleton, and after several hours of the hardest kind of trowel digging, we had the satisfaction of exposing the skeleton lying at full length on its back. Its skull, slightly turned to the right, rested on a flat stone at the western end of the grave. On the left side of the skull was a large sea-shell of the genus Busycon, from which the central portion had been removed, a common method of making vessels among the various peoples of America, and often found in burial mounds and graves from the Gulf States to Michigan. With the bones of the neck were several shell beads, also of a common form, and as widely distributed over the country as the Busycon Shells The arms were extended at full length along each side, and inclosed by the bones of each hand, resting on the hips was a spool-shaped ornament (which our explorations have proved to be ear ornaments) made of copper, and like those found with several of the skeletons in the mounds of this group. We have at the museum ear ornaments of this character from burial mounds in various parts of Ohio and west to the Missis- sippi in Illinois, and from Central Tennessee, but I have never found them in any of the several thousand stone graves of the Cumberland valley which I have explored, nor have we founda trace of them among the several thousand graves associated with the singular ash. pits in the cemeteries which we have explored mo the Little Miami valley, nor with the skeletons buried in the = stone mounds nor in many of the simple burial mounds of Ohio. They seem to be particularly associated with the remains of a people who practiced cremation to some extent, and who built many of the great earthworks of the Ohio valley. That it is an ent form of ornament, made from native copper, there can be dants or conquerors of this people in later times; and it is atin a all the recent Tudisn graves I have opened avail Seo that the form “i the oroare may have uliar etr of ornament has not oreen ee 10 doubt, although they may have been made also by the de- — 1886. ] The Peabody Museum's Explorations in Ohio. 1021 found; and if they were ever thade by the whites and furnished to the Indians, I have never happened to find any that showed evidence of the fact. We have certainly found them under such conditions in Ohio that they must have been buried with their owners long before the discovery of America. Then again, all we have found have been made by hammering pieces of native copper, and not by casting the metal. By the side of the right tibia of the skeleton in the grave wasa Copper pin, a wooden bead covered with thin copper, a few long, slender flakes of flint, and a fragment of some kind of an orna- ment made of shell. These long flint knives are of the same shape and character as the well known obsidian flakes from Mex- ico, and we have found them, as a rule, associated with copper far ornaments like those in this grave. They are sharp edged, and are as good knives as the Mexican flakes. While speaking of them in general terms as flint, they are in reality flakes struck from several varieties of stones, many of them being of a bright red jasper and others of chalcedony. The wooden bead covered with copper is of the same character as others we have taken from the burial mounds in which we have found the copper ear orna- : Ments. Close to the right hand and hip, but two inches above them, and covering a space a foot in diameter, were a mass of fragments of burnt human bones, with bits of charcoal mixed with ashes. These remains of a cremated body had been gathered from the place where it had been burnt, brought to this grave and Placed by the side of the body at the time it was laid in the grave. The close contact of the remains to the finger bones of the skele- ton, which were not disturbed, was sufficient evidence of this. Here, then, in one grave, we had found the evidence associating ~ it with the altar mounds and the rest of the earthworks about, in- ce dependently of the fact that the grave itself was within the earth wall Surrounding all the other works. We had found evidentiy the burial place of the people, and this was abundantly confirmed Eis 3 as our work progressed. We have now for two weeks been engaged in exploring this _ burial place, and during this time we have discovered eighteen graves, four large deep pits, and several holes dug in the gravel, as well as places where there had been fires, and numerous other interesting facts, many of which by themselves would be trivial, but which, when they are all put together, will give a far better 1022 Lhe Peabody Museum's Explorations in Ohio. [December, idea of the customs and works of the people who made the great earthworks in Ohio than it has been possible heretofore to obtain. All other explorations in the State have been fragmentary. No other systematic work has been attempted, and hence we have had plenty of theories built upon partial facts. We have much to do before the exploration is completed even of this single group. To give a detailed account of all we have found during these two weeks would, I fear, draw too much on the patience, and I shall only cali attention now to a few of the more in- teresting points. Individuality had its exemplification in this old cemetery, the same as it has in our modern ones, and the modifi- cations are so great that no two of the graves thus far discovered are alike. In one instance there were no stones about the skele- ton; in another a carefully built wall had been made of long, narrow, flat stones, and a regular wall, four layers high, had been made in the same way that a mason lays bricks, but without mortar. In some graves flat stones were placed at the bottom; in others the skeleton was firmly imbedded in the gravel, while in one the body had been placed on a thin layer of clay placed over the gravel. In one grave there were two skeletons, one ex- tended at full length on its back and the other crowded into the grave by the side of the right leg of the first. A child was placed ina small circular grave, the body having been so arranged that the head and the feet were not far apart. Most of the graves were comparatively shallow, extending from six inches to a foot into the layer of gravel. The deeper the grave the better the con- dition of the skeleton. One grave was dug to the depth of nearly four feet in the gravel, and was seven feet long by four in width. - At the bottom was a pavement of flat stones, fourty-nine in num- ber. On these stones the body had been extended, and the grave had been filled up with over three hundred stones, all of which had been brought from the river bed, nearly a quarter of a mile _ distant. Over these stones six inches of gravel had been placed, es _around and over which other stones had been regularly arranged. : grave and caused the skeleton to decay, only a few fragments be ing left.

In one was a pipe carved from stone which had been burnt with the body, and in another were fragments of a burnt copper ornament. I must give an account of the graves which were of particular interest. Grave No. 5 in our notebook was six feet six inches long, two feet nine inches wide, and one foot eight inches deep, measured from top of the stones. It was made with care, and the stones were carefully placed so as to form a substantial wall. The bot- tom was completely covered by four large, flat stones, on which the skeleton lay on its back. The skull was at the east end of _ the grave. When the body was put in the grave the knees were drawn up, the left hand rested on the body, and the right was laid straight along the side. The result was that the bones of the left hand were found in close contact with the upper ends of the tibiz, Which had fallen down between the femora. In the bones of each hand was a copper ear ornament like those I have mentioned. In the corner of the grave, near the bones of the left foot, was a large sea shell, from which the central portion had been cut away. _ Near this was a little cup carved out of stone, two canine teeth of a bear, each with lateral perforations, and in each tooth was the chalky remnant of a large pearl, Close to them was a large crys- tal of galena, and a knife made of a long flake of flint. On the Same side of the grave, nearly opposite to the shoulder and partly under the side stones, were eight of the copper ear ornaments in a bunch, and under them a long bone point. We did not dis- Cover them until we had taken out the skeleton and began to re- Move the stones, for it is our rule always to remove everything Placed by human hands, and to turn over every inch of dirt pre- viously disturbed. On taking up the flat stones, which were firmly imbedded in the gravel, and had their edges covered by the Side stones, we found the following articles, which must have been placed where we found them before the stones had been put down. Under the second stone (there was nothing under the first) near the center was a copper bead and smail thin pieces of iron, probably meteoric, but it has not yet been anatyzed, and it May prove to be bog iron which has formed in that place. As we have found several ornaments made of meteoric iron on the S of the mounds in this group, as well as two good-sized 1024 The Peabody Museum's Explorations in Ohio. [December, pieces of an iron meteorite, I strongly suspect that this iron will Prove to be the same. Under the third stone, were two disks or halves of a copper ear ornament. These were several inches: apart, and must have been so placed when the stone was put down. Near these was a wooden bead, with a thin covering of copper.. Under the next, or fourth stone, were several of the long flint flakes or knives, and eight inches from the edge of the stone was a small copper celt. These deposits, under the stones of which the body was tobe placed, certainly suggest the offerings of friends at the time the grave was prepared, and the various other objects placed in the grave with the body can, with equal reason, be looked upon as the property of the deceased, or as friendly offerings. At all events they are important as proof that the individuals buried here belonged to the people who built the mounds, as these several objects are of the same character as the many we have found on the altars, and with the few skeletons in the burial mounds of the group. Grave 15 of our notes was remarkable for the care with which the walls, sixteen inches high at the head and foot, were made of four layers of flat stones, while along the sides, in the clay above the gravel layer, were simply a row of stones. The skeleton was lying firmly imbedded in the gravel, extended at full length on its back, with the skull at the west end of the grave, while the toe bones were against the opposite stones. The skeleton thus extended the full length of the grave, which was six feet three inches, As with nearly all the adult skeletons, there was a cop- -~ Perear ornament in the bones of each hand. On the breast bone was a copper band. At the neck were two shell beads, and near the left shoulder was a flake knife. A few inches from the left a foot were about twenty of the long flake knives, carefully laid oe together, as if they had been Tappi in a piece of skin or es when placed in the grave. : With two other skeletons we found celts made of soft coal. : 16 se were- perfectly made, with fine smooth edges aid polished i. , in exact imitation of the ordinary stone celt or hatchet; — aiy would have been worthless for the uses to which stone re 24 it is li that they were ornamental or oae o + ly to one more grave, No. 18 of our notes.

This mass stood up eight inches from the gravel layer under the clay. Removing these Stones and gravel, we found loose gravel filling a pit just seven feet long and three feet four inches wide. At the depth of two feet we came to hard undisturbed gravel, and on this was a hu- man skeleton extended at full length on its back, with the skull at the south-east end of the grave. The bones were firmly imbed- ded in the gravel, and so dry that great care was necessary in re- moving this matrix. However, after six hours of unremitted labor with small trowel and brush, they and the several objects associated with them were all uncovered and left in place, even to the finger and toe bones, and a photograph was taken showing everything in place. In each hand was one of the copper ear orna- ments of the kind I have referred to so often. The finger bones were so arranged as to show that these ornaments had been clasped in the hands at the time of the burial of the body. An- other of these ornaments was on the neck bones in contact with the under jaw. On each side of the copper ornament was a canine tooth of a bear, with the lateral perforations. Partly over the bear’s tooth, on the left side, was a piece of native copper, which had been hammered roughly into a flat, thick, irregular sheet. This is without holes, and is probably an unfinished ornament. Above this, and close to the skull, was a small copper cone, like Many found on the altar of the great mound. Near the right shoulder was a large sea shell, like the others I have mentioned. = This skeleton, as it lay in the grave, measured five feet ten inches _ from the top of the skull to the tip of the great toe, and the in- _ dividual was not far from five feet four inches in height when = living. With the exception of a portion of the sacrum, which had entirely disappeared, this skeleton was taken out in a perfect con- _ dition. The decay of the sacrum was owing, probably, to the fact that a small round stone had fallen in such a way as to __ allow water to percolate around it. This skeleton is a good illustration of the absurdity of the common notion that as soon as skeletons which have long been buried are exposed to the air they fall to dust. I always have a quiet laugh when I read notices of that kind, and you may put all such accounts down to the inexperienced and clumsy work _ of the person removing the skeleton. The fact is that it requires ~ 1026 The Peabody Museum's Explorations in Ohio. [December, great care to remove the earth from about the bones, and very few persons will take the time to do it properly. As soon asa bone is uncovered most persons attempt to remove it at once, and of course it goes to pieces. Now if a skeleton is in dry earth ' or gravel, and is very dry and crumbling, the proper mode of procedure is to uncover the bones with great care, loosening the earth with the point of a small flat trowel and removing it from the bones by means of a small broom, or clothes brush, then let the moist air come in contact with the bone, or, if the air is very dry and hot, sprinkle the bones with water and let them absorb all they will. In this way the particles of bone swell and interlock, and after a while the bone can be safely taken up by avoiding force in removing it from the earth. In case the bones are in wet clay or earth the matrix must be removed with great care. In such cases the bones are soft and spongy and they must be allowed to remain in place until they have dried off; but they must not be exposed to the full heat of the sun, otherwise they will crack and splinter as they dry. Of course instances often occur where we find only minute fragments of a skeleton in a grave, all the rest having passed through a chemical change and been reduced to its earthly particles; but that every bone found in a grave can be preserved by using proper care I know from long experience to be the case. I may also call attention to the fact that the state of perfection of the skeleton, outside of certain limits, is not evidence, by itself, of the antiquity of the bones, as the conditions of burial, as well as the character of the bones must be taken into account. In our exploration of this burial place we found three large pits which were covered with gravel and stones, like the grave I have just described. These pits had been dug through the com- pact iron-cemented gravel below the clay, even to the depth of five feet, and all the material taken from them had been carr ied away. The pits were then filled with ashes and burned earth, = and covered with several inches of gravel and stones, like a ee. grave. The sides of the pit were not burned, so it is evident pa the ashes were not from fires on the spot. There were seve places uncovered by our excavations near these pits or g _ where fires had been made on the clay or gravel, but the sent had been removed, and hence it is probable that they had a it in these carefully marked pits. But what had become of t! A ETS, O E S Se RE SSA n = 1886.) An Interesting Connecting Genus of Chordata. 1027 It is to be remembered that in the great mound of the group of altar mounds there was a layer of gravel two or three inches thick, which we have called the concrete layer. This gravel was cemented by a large amount of iron, and it has been a puzzle where the iron came from. It was far too great in amount to have been derived from the clay in the mound above, and be- sides, the gravel of the same layer, about the edges, was loose and light without any mixture of iron. Now this iron gravel from the burial place is of the same character as that forming the concrete layer in the mound, and it therefore seems probable that these pits must have been dug for the purpose of obtaining it. As this gravel had been used during the extensive ceremonies which must have taken place at the time the mound was con- structed, the very place from which it was taken seems to have been held sacred and the pits therefore filled with burnt material, covered over and marked in the same manner as some of the graves. This again is further evidence of the connection of the burial place and the ceremonies which took place there with the altar mounds, The more we examine into the details of this wonderful group of ancient works, the more interesting and in- Structive they become. We have already spread before us the outlines of a grand picture of the singular ceremonies connected with the religious and mortuary customs of a strange people. There are still some touches to be given before the picture is complete, but it is more perfect than any other that has been drawn, and as our work goes on we may yet be able to fill it out, and finally present it as a perfect whole.— The Boston Herald. 3 "ry? We AN INTERESTING CONNECTING GENUS OF CHORDATA. BY E. D. COPE.

[December, There is found, lying in the median orifice of Bothriolepis, a bony valve, which is quite free all round. This has been supposed to represent the interorbital part of the carapace, and the uncovered parts of the orifice, at each of its extremities, have been supposed to be the orbits. An examination of numerous specimens of Bothriolepis canadensis Whiteaves, has lead me to oppose this lat- ter view. I have, on the contrary, considered the entire orifice to be probably homologous with the “ nasal pouch ” of the lampreys, and the mouth of the Tunicata and of the invertebrates.’ This character, together with the absence of lower jaw, would refer the genus to the Marsipobranchii or class of lampreys, or to the Tu- nicata. From its considerable resemblance in the carapace to the tunicate Chelysoma, and in the lateral arms, to Appendicularia, I referred Bothriolepis provisionally to that class. The Cephalaspididæ are more like fishes than the Pterichthyi- dæ, in that they have a distinct head and distinct orbits. They have, however, no lower jaw, and thus approach, if they do not enter, the Marsipobranchii. But they have no nasal pouch or nostrils, as has been observed by Dr. Lankester. This character separates them widely from either fishes or Marsipobranchii. It also gives color to the supposition that the orbits in this family represent the extremities of the median orifice of Bothriolepis. A highly interesting specimen, which I owe to the kindness of my friend, R. D. Lacoe, of Pittston, Pennsylvania, throws consid- erable light on this subject. It consists of the cast of the cranial | and nuchal buckler of a vertebrate allied to, but different from, — the families above mentioned. The fact that it is derived from 4 higher geological horizon than any of them, that is, from the. } Besides the typical specimen buckler are in my possession- the fact e of Ceph- se of Bothriolepis.

This structure makes it probable that the median orifice of the Pterichthyidz represents both protostome (nares) and orbits, and that these orifices have become differentiated in later forms. The protostome in Bothriolepis is covered by a probably movable valve. That the organ of smell should have been differentiated from a primitive mouth is altogether reasonable in view of the close relationship subsisting between these senses; but that the sense of sight should have had acommon orifice is not to be antici- pated. The recent re- markable discovery of a _Tudimental eye in the pi- heal gland of lizards does — not throw much light on the subject, since true eyes coexist with it in those animals, and the median eyes of the Pter- ichthyidæ had left the _ field long before the ad- He ` vent of Reptilia, in a phy- ~ logenetic sense.

Their borders are slightly elevated, espe- cailly above a shallow groove that connects the orbits behind them. Nuchal plate twice as wide as long, its posterior outline a little convex, its posterior external angle reached by the acute apex of the cephalic spine. The median anterior border of the cephalic buckler is damaged so as not to give its exact outline, but the muzzle was probably broadly rounded. The lateral bor- ders are nearly straight, and they diverge to near the base of the spine. The external border of the latter is gently convex, and turns inwards posteriorly. The surface is marked by longi- tudinal lines of flat tubercles, or raised areas, which are separated by narrow grooves, and have various lengths. Those on the head are usually as wide as long, while those on the nape are generally much longer than wide. Those near the borders are always broken up, and those at the side and in front of the orbits are irregularly distributed. Cephalic border and spine smooth. The size varies. The type specimen has the head as large as a fully-grown Amiurus catus, but parts of others indicate individ- uals approaching double that size. Returning to the presentation of the systematic relations of this form, it may be observed that in spite of its resemblances to the Pterichthyide and the Cephalaspidide, it must be dis- tinctly separated from both families.

The structure of the fins of this order being unknown it cannot be referred to either of the three primary divisions (Crossoptery- gia, Chrondostei and Actinopteri) with certainty. Supposing it to belong to the last named, it agrees best with the Isospondyli, but apparently differs in the lack of some of the elements of the suspensorium of the lower jaw. There is no sufficient evidence of affinity to the Nematognathi, which is probably a modern group. The Mycteropide then occupy a position between the Anti- archa and Marsipobranchii (Monorrhina) on the one hand and the _ fishes on the other. They would, with the latter, enter the |“ cladu” Amphirhina of Heckel, if that division be regarded as _ defined by the presence of two nareal orifices. But this disposi- tion of them would violate truer affinities to the orders without lower jaw and scapular arch, for which the term Agnatha (Haeckel) may be retained. As compared with Cephalaspidide, _- Mycterops approaches nearest to Didymaspis Lankester. The : Mycteropide may be regarded as descendants of the Pterichthy- didæ, and ancestors of the Placoganoidei. Since the latter occur €arlier in geological time (Devonian) than the Mycteropida: (Car- boniferous), we may suppose that Mycterops is a descendant of a Silurian or Devonian type with a single median nostril, which will be a family of Monorrhina. From this hypothetical family the Arrhina (Cephalaspidide, etc.) and the Marsipobranchii (lam- Phreys) may then be regarded as descendants. The former los nares by degeneracy; the latter are degenerate in other respects. 1032 _ Recent Literature. { December, EDITORS’ TABLE. EDITORS: A. S. PACKARD AND E. D. COPE. The editors of the American NATURALIST wish to call the attention of American students to the fact that their pages are open for the prompt publication of summaries of the results of original investigation, which for any reason it may be deemed desirable to place on record before the issuance of the completed account. Looked at merely as a means of securing priority, prê- , liminary communications are not over praiseworthy. The credit of making a discovery should not be the sole end of investigation, and an attempt to hurry into print so as to forestall some other worker in the same line is not highly meritorious. The student of science should have a higher aim; and happily quarrels for priority are far less frequent than they have been in years past, ‘thus indicating that a higher end has been sought. Preliminary communications have another value than the mere anticipation of another. They place before others, working in the same line, an outline of the results at the earliest possible moment, and thus often furnish invaluable assistance. Fully as great is their value to the student working in another line. The completed paper is usually long and frequently prolix, so that it is a severe drain upon the time to wade through it for the facts desired. The pre- liminary communication, on the other hand, is usually short and concise; it contains only the more salient facts and omits the larger part of the speculations. In this way it becomes more easily available for reference, while it does not withdraw from the value of the more detailed article, From these two points of view the preliminary communication is valuable and deserves en- couragement.

The principal feature of this paper is the extent to which it increases our knowledge of the bathymetrical distribution of the forms enumerated, and points out the coincidences between depth of occurrence and points of structure. These lists record forty- three species as coming from below the 1000 fathom line, while twenty-two were taken from a depth greater than 2000 fathoms. The greatest depth recorded is 2949 fathoms, and from a single station of this depth, about 350 miles east of the mouth of the Chesapeake the trawl brought up Acanthephyra agassizit, A. brevi- vostris, Notostomus vescus, Hymenodora glacialis, Parapasiphaé sulcatifrons, Hepomadus tener and Sergestes mollis. Of the per- tinence of the first of these to these great depths some doubt is expressed, as at another time one was caught swimming at the Surface. All of these forms it is to be noted are macrurous, Some of the deep-sea forms are colorless, but most are of some bright shade of red or orange. Their eyes have undergone a careful superficial examination. In some the black pigment, the corneal facets and the like are much as in shallow-water forms, €xcept that occasionally the eyes are smaller. In Munidopsis and Pentacheles the visual elements are apparently lacking, while in others the pigment is light colored and the visual elements are reduced in number. In some of the deep-water shrimps there is a curious accessory organ borne on the eye-stalks which may be Phosphorescent in its nature. It certainly deserves careful histo- logical examination at competent hands. In the eggs, too, a peculiarity is noticed. Among the shallow-water decapods the eggs are usually so small that it is a matter of some difficulty to Cut sections of them, but in these deep-water forms they attain a very considerable size, those of Parapasiphaé sulcatifrons having a diameter fifteen times those of the common soft-shelled crab, Neptunus hastatus. We have a little fault to find with the present paper. The first is that which is found in all of the Fish Commission publi- Cations, but which here is not as bad as in embryological work— =~ the use of process cuts. We notice a tendency to the creation of new families which hardly seems to be warranted.

[ December, and almost entirely ignore the physiological aspect of animals and plants. A student has gained a valuable fact when he has learned the name and structure of any organ, but until he knows its function and the method in which it is performed his knowl- edge regarding it is incomplete. The present hand-book aims to teach the physiological as well as the morphological side, and thus fills a place which no other work in the English language does. It is, we understand, but a portion of what is intended, and this fact should be borne in mind in the following account. Still in its present condifion it is admirably adapted for grounding. students in biology. There are numerous exercises for the labo- ratory, and the directions for these are excellent; they tell the student what to do, but leave him to describe the results, thus giving the instructor a test of the student’s progress. The first three chapters are devoted to the phenomena of life and the study of organic matter, then follows a chapter on the cell, after which comes the study of special forms. Of these there are two, the fern—Pteris, and the earth-worm ; and we agree with the authors in regarding these two forms as well adapted for study by the beginner as any. The book is well illustrated, most of the cuts being original, and though made by photo process they are usually clear and free from broken lines. A rather careful examination of the book reveals but little which calls for adverse criticism. On p. 123 it is stated that “all the organs of the body are originally developed from the walls of” the ccelom of the earth-worm, which is not true in the sense in which it will ordinarily be understood. Again one might criticise the use of “ ectoblast ” and “entoblast” (p. 178) for the inner and outer germ layers. Several other terms have priority, and it seems needless to multiply terms for each stage in the de- velopment of the organism. To be consistent the authors should replace the the term archenteron on p. 149 (not on 148) by me- senteron. The proof-reading has been very well done, and the graphical errors rare. The printer is, however, to be criti- cised, as he has used a badly worn font of type, and broken and battered letters are much too common. With the exception of these few points and a few of like character we have nothing but praise for the book. .

PACIFIC IsLanps.— Captain Bridges’ Cruises.—Captain C. Bridges’ notes upon cruises among the Pacific islands (Proc. Roy. Geog. Soc., Sept.) give a good idea of the present condition of the islands visited. Inthe southern section of the New Hebrides the tem- perature ranges from 62° in July and August, to about 92° in January and February. The natives of Aneiteum are devout Christians. Among the Melanesians of these islands, communi- ties of Polynesians preserve themselves distinct. The staple pro- duct is copra, the dried pulp of the coco-nut, and several white traders are engaged in procuring it. On Sandwich or Vaté, the women shave their heads completely, while on Espiritu-Santo they leave a ridge of hair from poll to forehead. The houses are neat and clean; on some islands the unmarried men sleep ina special house. The people of the Solomon isles are good seamen. Their canoes, except as New Britain and New Ireland are approached, have no outriggers. The New Britain people go quite naked, and lack the vigor of the Solomon islanders. They are the only cannibals of the region who are not ashamed of their cannibalism. It is not etiquette in New Britain to ask a man his name, it should be asked of some one else. Captain Bridges mentions a curious mode of shark-catching practiced by the Kingsmill islanders. They tow from a canoe a large line with an open noose. Through the centre of the noose is passed a small line with a bait on the end. As the shark follows the bait, it is hauled in, until at last the fish has his head in the noose, which is quickly tightened. The people of the Ellice islands are all Episcopalian Christians, while those of the Gibert islands are partly Christianized. The Marshall island men are tall, the women singularly short. The dress of the latter consists of two ornamented mats tied around the hips so as to resemble somewhat a sleeveless and low- necked gown. On these islands and some of the Carolines the women tattoo the hand and fore-arm in such a way that they ap- pear covered with open-worked mitts. The money of Yap (Car- Olines) is in the form df disks of arragonite, like great grindstones. They are quarried in the Pelew islands, and some pieces weigh three tons. The people of Ni¢guor and Greenwich islands, two low atolls of the Carolines, are almost gigantic, and are now ruled by queens. In the Pelew islands the younger men have large “club-houses.” Women may not enter the club-house of their own village, but may without losing caste visit that of the next. The constitutional government of Tonga seems to be a success. Most of the Tongans are now fearless horsemen, though man Can remember the time when there was not a horse in the Archi- = pelago.

While in the south of New Guinea the natives are in the stone age, in the north they use shell implements. The New Zealand Earthquake-——Dr. Hector’s preliminary re- port upon the recent volcanic eruption in New Zealand enable some idea to be formed of the magnitude of this convulsion of nature. The outbreak commenced at half-past two on the morning of June roth, byan eruption from the top of Wahanga, the northern- most summit of the Tarawera range. This was in a few minutes fol- lowed by a more violent outburst from the summit of Ruawahia, the central peak of the same range, and this was shortly afterwards followed by a terrific explosion from the south end of Tarawera itself. For two hours vast quantities of steam, pumice-dust and stones were poured out. A great crack or fissure was formed along the east face of the mountain, and Mr. Percy Smith reports that the whole east end was blown away, the débris covering the country for many miles. Up to this time the earthquake shocks _which occurred were not very violent, but about 4 A. M. came a powerful earthshock, attendant on the outburst of an immense volume of steam from the site of Rotomahana lake. By 6 A. M. the period of active eruption had passed; but the town and vicinity of Wairoa were smothered in the mud condensed from the cloud of steam and solid matter thrown up from Rotomahana. The formerly abrupt sides of Tarawera are now every where softened by great slope deposits of material ejected from a range of volcanic vents, seven of which were ina mild state of eruption when visited by Dr. Hector. From the south-western extremity of Mt. Tarawera a great fissure runs south-westward for some seven miles. The eastern side of this has a nearly straight wall, but the western is very irregular and is continually altered by the falling in of its walls as they are undermined by the action of seven powerful geysers which at irregular intervals throw up great volumes of boiling water, stones and mud to a height of 600 to 800 feet. Lake Rotomahana has disappeared in this chaos. The largest mud geyser occupies the site of the Pink terrace, another that of the White terrace. At its north- ern end this fissure commences in a great rent 2000 eet deep, 500 wide, and 300 deep on the side of Tarawera and the southern end is a bold semicircular escarpment. . of material.

E. Gleerup, a Swede in the ser- vice of the Congo Free State, has recently crossed Africa from the Congo to Zanzibar. He had been left for nearly a year without _ supplies at the remote station at the seventh cataract of the Stan- ley falls, and finally left for Europe by the aid of funds furnished by Tippoo Sib, the rich Arab trader. The journey to the east coast occupied six months. Reports by the late Sir P. Scratch- ley, British Special Commissioner to New Guinea, gives a de- scription of the characteristics of the natives of different portions of the coast of British New Guinea. The littoral seems to be well inhabited, except some portions of the north-east coast. Two tivers, the Davadava and Hadava were discovered in Milne bay, the latter river a large one.

THE VEINS OF SOUTHWESTERN CoLoraADo—It is quite impos- ` sible to thoroughly understand the complicated vein-structure of the San Juan region without an intimate knowledge of the geo- logical history. The details of the stratigraphy are very interest- ing, but we cannot stop to review them here. Suffice it to say that the succession of the strata, aside from local features of little importance for our present purpose, is much the same as in typi- cal sections from the Rocky mountains through Wyoming and Northern Colorado. The real vein-history begins with the close of the Cretaceous age, when the great folds took place which afterwards became the Seat of volcanic action. I must refer to the previous papers read at this meeting of the Association for much of what might properly be brought into discussion here, and we may at once proceed to a brief description of the veins and their arrange- ment. In the period of the andesitic outflows the country comprising the great San Juan Central area was so situated that the lavas did veins. The earliest appear to be those of the La Plata district, rated from these two basins, and has been the seat of much sec- ondary action, so that the date of its initial stages in vein-forma- tion is difficult to determine, but with results similar to those of the latest epoch. I am strongly of the opinion that the genesis was but little, if any, later than that of the other two sets. In the Central San Juan area the complexity is very great, and yet the distribution of the veins may be brought into order in a _ beautiful system with surprising regularity in the grouping. __ There are six radial zones passing out from Red peak (the geyser 1 Paper read before Section E, A. A. A. S., Buffalo, 1886, 1044 | General Notes. [ December, basin described at the Buffalo meeting in another paper) and ex- tending as far as the confines of a depressed area which was caused by faulting in the trachytic period. These zones are tra- versed by central, nearly vertical veins (“parent fissures,” as I have elsewhere styled them), bounded upon each side by veins converging laterally and from above downwards. The mid-ribs are free-gold bearing, and they represent three trends intersecting near Red peak. These trends are about N. 80° E., N. 38° E. and N. 38° W. The zones vary in width, but between each two there is a barren belt of greater or less breadth. Beginning at the north we have (1) the arsenical zone, characterized by miner- als carrying high percentages of arsenic; (2) the ġismuth zone; (3) the galena-gray copper zone; (4) the antimonial zone, practi- cally the prolongation south-westward of the arsenical wedge; (5) the argentiferous-galena zone, opposite the bismuth wedge, | and ‘6) the su/phuret zone, a wide area with few veins, but these rich and carrying true silver minerals (sulphides) largely. The faults and the vein-filling appear to have occurred subse- quently to the trachytic ejections but prior to the rhyolitic period. The evidence is that the gradual elevation of the Red peak focus caused the subsidence and faulting along the edges and across -two of the three stated radii of the depressed area, but that the deposition of the veins along the arsenical-antimonial trend was later than the rhyolitic period, or in its closing stages. After this the veins of the Red Mountain area were much modified by the secondary action of ‘hot springs and geysers. I have given here the mere outline of the facts, and but a small Comstock.

The scuta belonging to the tail are distinct from each other, and not coéssified as in Deedicurus. The species may be named and described as follows: Caryoderma snovianum Cope, sp. nov.—The dermal scuta may be arranged in four classes. First, the smallest, which are sub- quadrate in outline, and flat; one of the flat faces, probably the in- ternal, smaller than the opposite one, and more spongy. Six of these; the largest 15™™ in, width. Second, larger scuta, sub- hexagonal or pentagonal, or oval, with the dense smooth exter- . nal face rising towards and produced beyond one of the borders of the base as a flat more or less angular cornice.

It is probably a case of persist- ence, however, for since the Miocene beds of the Parana have been shown by Ameghino to contain ancestral Glyptodontide, the North American ancestors of these are to be sought in beds earlier than the Loup Fork. The species was discovered by Mr. Charles H. Sternberg, in Northern Kansas. It is respectfully dedicated to Professor F. H. Snow, of the university of that State. GEOLOGICAL News.—General—In these days of earthquake theories that of M. De Montessus (Rev. Scient., 1886, 369) is worthy of notice. He starts by enumerating the three chief the- ories of the constitution of the earth: (1) A central fluid nucleus with a more or less thick crust; (2) a central solid nucleus and a solid crust separated by a spherical liquid ring ; (3) a solid inte- rior with chambers filled with fluid. Postulating the correctness of the first theory, which prevails in France and holds its own in other countries, he then gives, as the result of calculations made upon 4943 shocks, the statement that earthquakes are more fre- quent when the moon is on the meridian than when it is at right angles with it. From this he passes to the fact that were the ocean composed of a dense fluid, like mercury, the tides would consist of an actual transport of matter following the moons course, May not such tides take place below the earth’s crust ? Capt. Boulanger, in 1880, dared to doubt that the earth moved as a whole, so that the velocity of every point is proportional to its distance from the center. The patient study of the sun spots has proved that there is in the sun’s matter an internal and external circulation quite different from that which would result from a rotation in every point proportionate to the radius, Vortex mo- tions, according to M. Faye’s law, must be produced in fluids the layers of which are in movement with slightly differing veloci- ties. Add these vortex movements to the subterranean lunar tides, and M. Montessus’ earthquake theory is outlined. : Paleozoic—Professor Ed. Hull, Mr. Mellard Reade and others in Britain, with Mr. Crosby in America, maintain that in Palæo- zoic times the North Atlantic and the North American continent in the main changed places. In the words of the first of these: “Tf it be allowed as a general principle that the originating u Jay in the direction towards which the sediments thicken, am opposite to that in which the limestones are most developed, n coħclusion is inevitable that the Atlantic was, in the main, a lan surface in Palaeozoic times.” .

Secondary.—The central region of Tunis, according to M. Rol- land, consists in great part of a mass of senonian beds with lime- stones yielding inocerami and cephalopods. This mass is here and there capped by nummulitic beds. These beds are found all around the Mediterranean region, but those of Algiers and Tunis are characterized by peculiar species. M. Thomas has discov- ered beds of phosphate of lime in Tunis. In the south-west are rich and very extensive Eocene deposits, while near Feriana there is a small bed of Cretaceous age. In the Albian marls of Con- _ Stantine, in Algeria, there are notable Cretaceous beds of this minera Quaternary. —M. Reviere, who at the meeting of the French Assoc. Adv.

That portion of the book which has already appeared is well illustrated by nearly four hundred photo-engravings. Most of these illustrations are taken from localities in Bavaria. The author, however, has not hesitated to draw on any source that would serve his purposes better than those at hand in his own country. The result is a most satisfactory text-book of geology, in which all the most modern methods of geological research are described, and the results to which each leads carefully given.

The next five pages con- tain a list of the most important works devoted to the subject and the periodicals in which petrographical articles are published.

MINERALOGICAL News.—Ptilolite? is a new mineral, described by Cross and Eakins, from Colorado. It occurs in the cavities of a vesicular augite-andesite found as fragments in the conglomerates of Green and Table mountains, in Jefferson county. It forms delicate tufts and spongy masses composed of short hair-like needles which are usually deposited upon chalcedony in the pores of the rock. Under the microscope these needles are seen to be colorless, transparent prisms about .oo1™™ in diameter, terminated by a basal plane. Their extinction is parallel to the prismatic axis. An analysis of the purified material yielded Mr. Eakins the following result: _ 50, AO, œO KO N0 Ho 70.35. 11.90 3.87 2.83 0.77 10.18 - This corresponds to the formula Ro Al,O,, 10SiO, + 5H-0. The mineral is interesting as being the hydrated form of the most acid anhydride known among the silicates, with the exception of the rare mineral milarite. A pseudomorph of limonite after pyrite? recently found in Baltimore county, Maryland, con- tains six of the seven possible crystallographic forms of the regular system.

The various colors which it possesses are probably due to the admixture of a copper molecule 2CuO PO; 4H,O. The presence of iron salts would tend to give a greenish tinge to the mineral. Under the micro- scope it was seen to be composed of minute grains or short thick fibers, weakly doubly refracting, with a high refractive index. The extinction was parallel to the long axes of the fibers. A consideration of the arrangement of the fibers in the veins, the composition of the rock in which the mineral is found, and its as- sociation with epidote, lead the authors to the supposition that it may have been derived from apatite.’ PETROGRAPHICAL News.—The gabbros occurring near Balti- more, and the hornblende rocks associated with them have been made the subject of a bulletin of the U. S. Geological Survey,” The treatment of these rocks by the author is very thorough. The paper opens with an introduction calling attention to the fact that eruptive rocks may, under the influence of heat and press- ure, become schistose and in their characteristics very like the crystalline schists which have been derived by the alteration of aqueous formations. The main portion of the work is devoted to the tracing of hypersthene gabbro into a schistose rock, called by the author gabbro-diorite. The massive gabbro consist essen- tially of a fine to coarse grained mixture of bytownite, light-green diallage and hypersthene in varying proportions. In addition to these there are also contained in the gabbro a little yellowish- brown hornblende, strongly pleochroic and full of minute black rock, containing in addition to the plagioclase and hornblende a considerable amount of epidote and some garnet, apatite, rutile, Sphene, etc. In the case of the alteration of hypersthene the author supposes a reaction to have taken place between this 1 Cf.

[ December, mineral and the feldspar of the rock, the latter supplying the former with the necessary aluminum required to build up the hornblende molecule. In addition to the two rocks mentioned, there are in the same region olivine-bronzite-gabbros, feldspathic peridotites and Iherzolites. In some of these rocks the feldspar has undergone a rather unusual alteration, viz., into scolecite. Other rocks, composed entirely of bronzite or hypersthene with or without diallage, are mentioned and briefly described. These olivine and pyroxenic rocks have given rise to much of the serpen- tine so generally found in their neighborhood. In the August number of the American Journal of Science, Mr. J. S. Diller’ has an article on the peridotite of Elliott county, Kentucky. This rock, according to the author, occurs in well-marked dykes cut- ting Carboniferous sandstones and shales. A microscopic €x- amination shows it to consist of olivine and pyrope, with a small amount of ilmenite as primary constituents, and serpentine, dolo- mite, magnetite and octahedrite as secondary minerals. The in- phibole, however, the fibrous mineral in the rim is biotite. F rom a comparison of the composition of the peridotite and the inter- sected sandstones and shales and the discovery of both endo- ation of the rocks collected there have established him firmly in the belief that the granitoid and the glassy rocks are of entirely distinct eruptions, which took place at two different periods re- mote from each other, and that in many cases minute differences of chemical composition have produced effects greater than m erate differences in the depths at which the roc í : moreover claims that a mere study of the slides and hand speci- mens is not sufficient to overthrow his own t sion of rocks in the vicinity of the Comstock lode.

By a process of silicification these carbonate-bearing layers were transformed into the various kinds of ferruginous rocks now met with in this region. In some cases silicifying waters decomposed the iron carbonate in place, producing tremolite or actinolite and magnetite, which with the excess of silica remaining formed the actinolitic schists so frequently found associated with the iron ores. In other cases direct oxidation of the carbonate gave rise to bodies of hematite. In still other cases during the silicifica- tion of the rocks and the decomposition of the carbonate, the iron was removed by leaching and deposited in other places as it be- came oxidized. The jasper is supposed to be secondary and to have been deposited upon the removal of the iron carbonate in the process of silicification. The various theories which have heretofore been put forward to account for these interbedded iron and jasper layers are all in turn examined and pronounced in- sufficient to explain the phenomena met with everywhere in the study of the region. BOTANY .! Tue WIND AND THE TREE-TOPS.—Since 1875 the writer has observed, in various parts of the country, 156 instances of injury to the trunks or branches of trees by win Of all ordinary trees the common red maple appears to suffer most in hard winds, and the whole 156 observed cases of injury were confined to the various species of deciduous trees, The writer has seen hundreds of long-leaf pines in Georgia and Flor- ida that had been blown up by the roots, but not one injured in trunk or branch while the tree was yet standing. Also close in- quiry in Iowa and a whole summer’s observation among the white pines of Tennessee failed to reveal a single case in which a tree of that species was injured by the wind. Of the 156 ob- served instances of injury sixty-one per cent were limbs split off at the crotch. The crotches of a tree are its weak points. Nature recognizes this fact and guards against the weakness by swelling out the wood about the points of branching. Notably is this true of the white pine. Ina large tree of this species the limbs come out in regular whorls about two feet apart. Midway between each two successive whorls the central axis of the tree has a minimum size. Above and below this point of least circumference the Sbe gradually swells out to support the successive sets of ranches In sixty per cent of the observed injuries the trunk divided _ into two or more large nearly equal branches, and one of these 1 Edited by Professor CHARLES E.

These large limbs, swaying in a hard wind, act as great levers, and are frequently not sufficiently sup- ported at the crotch. The meaning of all this is that a tree of which the trunk habitually divides into large nearly equal branches is much more liable to be injured by the wind than one having a strong central ‘axis with many small limbs as, for example, the white pine. Thus the accumulated effects of the wind have undoubtedly been to develop excurrent forms of tree-top. But the question naturally arises why pines, spruces, etc., have this form in greater perfection than other trees. Well, in the first place deciduous trees are usually injured by the wind only while in foliage during the summer months; but evergreens, being always in foliage, are practically exposed to the action of the wind for at least twice as great a time each year as are maples, elms, etc. Then too, ac- cording to palzontology, the cone-bearing evergreens came into existence many thousands, perhaps millions, of years before any tree that annually sheds its leaves. Thus the coniferous evergreens have had a vastly longer time in which to accumulate the effects of the wind and develop an excurrent form of top than have de- ciduous trees.—B. F. Hoyt, Manchester, Towa. A Hysrip ArrLe.— Recently a student brought me a “Ben Davis” apple characteristically marked throughout a little less than three-fourths of its surface, the remainder (a wide crimson streak from stem to calyx) having undoubted marks of the “Jonathan” variety. The tree from which it came is a Ben Davis,” and a “ Jonathan” tree stands within a distance of sev- eral rods. Upon cutting the apple it was found that the bee zation was confined to two carpels, and that the development © the flesh of these and the corresponding calyx-segments had been somewhat greater longitudinally and considerably less tra versely than for the remaining carpels. Upon tasting the flesh 0 the “ Jonathan ” part of the apple it was found to differ quite per ceptibly from that of the “ Ben Davis ” part. =. It is probable that we have in this apple an example of the 1m- mediate effect of the pollen upon the fruit. In this case = “ Jonathan ” pollen affected the fruit (a) by changing thé color the skin, (b) by causing the hybrid segments to grow longer an narrower, thus approximating nearer to the “ Jonathan form, and (c) by changing the taste of the flesh.— Charles E. Bessey. = Ruppra MARITIMA L. ın Nepraska—This maritime plant oe lately been brought to me from a pond near one of the many a springs which occur in the vicinity of Lincoln.

Y., by Paine, who says of it: “ This plant and its companion [ Vazas major] are new to the interior, having been known hitherto as exclusively maritime ” (Eighteenth Ann.

The distance from the Nebraska station to the Gulf of Mexico is about 800 miles.— Charles E. Bessey. THE ROUGHNESS OF CERTAIN Urepospores.—Recently while examining the uredospores of Puccinia coronata, a common rust of the oat, a student in my laboratory complained of the difficulty he had in making out the prickly (stachlig) surface of the spore- wall. The spores had been mounted in water in the usual way, - and it was with the utmost difficulty that any roughness of the surface could be made out, and when made out it was so faint as | to warrant the remark that “a character so difficult to be ob- served and so likely to be overlooked should not be made use of in descriptions.” The spores, in fact, appeared in most posi- _ tions to be perfectly smooth. e suggestion was made to ex- _ amine them mounted dry, when lo! the prickles appeared with _ the greatest distinctness. This hint may be worth remembering = in much of our work in botanical laboratories. — Charles È Bessey. ANOTHER “ TUMBLE-WEED.”—While riding through Phelps and _ Kearney counties, in South-central Nebraska, my attention was _ Called to great masses of some much-branched, white-woolly plant which occupied the ditches by the side of the railway. Its appearance was so odd and so different from anything I had ever Seen that I could not conceive what it could be. A fortunate Stop of the train outside the limits of a town allowed me to Secure specimens, which upon examination proved to be Psoralea enuifiora Pursh. The leaves had fallen and the naked branches, in drying, had diverged still more than in life, giving to the plant 1054 General Notes, [ December, an appearance quite different from that which it bears when grow- ing. The mode of detachment is the usual one of the formation of a joint at one of the lower internodes. In some cases two such joints were observed. The break at the joint is smooth and even, and reminds one of the separation of a leaf from its twig. It may be well to say that the plant under consideration is densely silky woolly in every part excepting its principal stems. It is certainly not “ minutely hoary pubescent when young,” as described in the manuals (Gray, Man., p. 129; Coulter, Man., p. 56). On account of the loss of leaves it is impossible to deter- mine whether this may not be the variety odtuscloba of Watson (Bib. Index N. A. Bot; p. 255). If so this is a much more northerly range than this variety of the species was supposed to possess. In all cases but one the variety is said to be a native of Texas. Creutzfeldt collected it in “ Kansas” in 1853 (Pacific Railroad Report, 2, p. 126), and from the date of its collection (June) it must have been found in Eastern Kansas. Carruth, however, does not record it in his catalogue of Kansas plants (Trans. Kan. Academy of Sciences, Vol. v)— Charles E. Bessey. BotanitcaL News.—The October Journal of Botany contains a paper, by Baron F. von Mueller, on “New Vacciniacee from New Guinea.” A new genus is described under the name Catan- thera. It contains one species, C. /ysifetala Mueller, which ap- pears to have affinities with Oxycoccus, though strangely it shows relationship alwish the toClethrez and Pyrolacee. It is an epi- phyte. In the same journal James Britten contributes an arti- cle on “The nomenclature of some Proteacez,” in which the question of priority of Salisbury’s names in the Proteads and other groups of plants is discussed. He says: “I am of opinion that there was a tacit understanding on the part of the botanical leaders of the period, including Brown, Banks and Smith, that Salisbury’s work and names should, as far as possible, be ignored, not only on account of their strong antipathy to the man himsell, but also, in Smith’s case at least, to the views of classification which Salisbury promulgated ;” an outrageous proceeding if true, as it appears to be. Dr. Newberry gives additional reasons, 1n the October Torrey Bulletin, for regarding Pinus monophylla as but a variety of P. edulis. He says: “In the Rocky mountains all are two-leaved ; in some arid portions of Nevada the tree, > dwarfed to half its normal size, and all the leaves are single. Mi ‘way between these districts, in Southern Utah, may be found thou- sands of trees in which the leaves are half double, half single. —— Dr. Gray’s Memorandum of a revision of the N. A. violets, 1n the Botanical Gazette, indicates certain interesting changes of eh ment and nomenclature. Viola delphinifolia Nutt. becomes ae datifera Don.; V, cucullata Ait. var. palmata becomes y. par- mata L., while V. cucullata Ait. is considered to be “an ak cleaved variety of the Linnean V. palmata.” The suggestion t 1886. Entomology. 1055 V. pedatifida Don. is “ probably only a marked geographical va- riety of that species [ V. palmata L.] with all the leaves finely dis- sected,” is worthy of further attention. In the Mississippi val- ley, where the three forms all grow, often quite near one another, their relations could be well expressed by considering V. pedat- ifera one extreme and V. cucullata the other, with V. palmata as an intermediate form. However, it will not do to consider the intermediate form, which is far less common than the others, as the type of the species. It is simply an intermediate form, and not a very constant one either. L. H. Bailey’s Preliminary synopsis of N. A. Carices (Proc. Am. Ac. Arts and Sciences) came to hand late in October. It contains notices of 289 species including, in addition to the strictly North American species, those of Mexico, Central America and Greenland, ENTOMOLOGY. A REMARKABLE CASE OF LONGEVITY IN A LONGICORN BEETLE (EBURIA QUADRIGEMINATA).—On the 11th of July, 1886, I caught at sugar, which had been placed upon apple trees for the purpose of attracting moths, a light brown long-horned beetle, marked with ivory yellow spots on the elytra. My attention was par- ticularly attracted at this time to the insect on account of a pecu- liar creaking sound which it began as soon as I picked it up. I had no difficulty in finding that the sound was produced by the rubbing of the posterior margin of the prothorax upon the anterior . margin of the mesothorax. The same sound could be made after the insect was dead, by working backward and forward its head and prothorax. Several days after this occurrence I captured a specimen, similar to the first, upon the clothes of a friend, but it disappeared before I reached home. Onthe 17th of July I found a third specimen on a tree but a few feet distant from that upon which I discovered the first specimen; this individual was also evidently attracted by the sugar. Five days later, July 22, 1886, another specimen came into my posession under much more re- _ markable circumstances. Dr. Boyd, of Dublin, Wayne county, Ind.; called my attention as I was walking along the street, and at once proceeded to remove two small corks with which he had closed two openings in the door-sill of his office. He then re- quested me to explain what had made the tunnels that evidently extended some distance into the sill. In reply to my questions, he stated that his attention had been called to the freshly made Openings early in the morning; at that time the holes were much smaller, and were ragged around the edges. These rough edges he had smoothed with a knife so he could stop them tightly with corks. A short time after he made the discovery mentioned, his attention was attracted by a buzzing noise which came from one of the tunnels. This he put an end to by pouring chloroform into the opening, and then plugging it up with a cork. There had 1056 General Notes. [ December, been no sound of life from the other tunnel, but he had closed it in the same manner. Upon hearing this I removed the cork from the tunnel where the sound had been heard, and in a moment dragged out by its antennz a beetle, similar to those whose finding I have already described. This beetle is Eburia quadrigeminata Say. Mr. Thomas, in the “Sixth Report of the Illinois State En- tomologist” describes the imago as follows: Æburia quadrigem- enata, “ Body, entirely pale yellowish-brown; antennz hardly more obviously hairy on the basal joints than on the others; thorax, with two black tubercles above, rather before the middle, placed transversely, and a short spine each side on the middle of the length of the thorax; elytra, rather paler than thorax, each with two double, somewhat elevated, bright-yellow, abbreviated very short lines; the two members of the basal spot equal, the other spot is placed on the middle, the inner member is shorter than the exterior one; tip, two spined, the exterior spine the longest; intermediate and posterior thighs, two spined at tip, the inner spine rather longest.” Mr. Thomas also states that the in- sect is from three-fourths to an inch in length, and that its larva lives and bores in the honey locust (Gleditschia triacanthus Linn), and from this fact it gets its name of the honey locust borer. A closer examination of the tunnels in Dr. Boyd’s doorstep showed that the external openings were in the middle of the length and breadth of an ash door-sill and about four inches dis- tant from each other. The size of the tunnels increased rapidly within until the diameter was three or more times as great as at the exit. They extended downward and backward respectively three and four inches. The sill was of painted ash and it, as we as the whole building, rested directly upon a solid brick founda- tion. After having completed the above observations, I did not hesitate long in coming to the conclusion that the eggs which had produced this beetle and its fellow, that had made good its escape, were laid in the green wood in the tree. In response to my questions, Dr. Boyd made the statement that the building was erected in the Spring of 1867. This would make these insects not less than nineteen, and probably twenty or more, years old, _ Since the timber was dry when put into the house. Upon investi- gation I find that Professor Packard in his “ Insects Injurious te Forest and Shade Trees,” makes no mention of this beetle, but at he has recorded two cases of unusual longevity in beetles which will be of interest. in this connection. In both instances these beetles have belonged to the family Cerambycide or io gicorns. The first mentioned case was that of a specimen 0 _ Monohammus confusor Kirby, the common longicorn pine-borer, which Mr. A. C. Goodell, of Salem, Mass., presented to the Peabody Academy of Science. Mr. Goodell took the insect from a bureau that had been in the house for fifteen years and was new when bought. | 1886. } Zoology. 1057 kind, issued from this table-leaf; the first one coming out twenty and the last one twenty-eight years after the trunk was cut down.” The proof of the identity of these beetles is not com- plete, but Professor Packard thinks they were Cerasphorus balte- I find that Eburia guadrigeminata is not given in Hubbard and Schwarz’s “ List of Coleoptera found in the Lake Superior re- gion,” nor in the “ Contribution to a list of Celeoptera of the Lower Peninsula of Michigan,” by the same authors. But in Schwarz’s “List of species” of Coleoptera found in Florida, Eburia quadrigeminata is mentioned as being “not rare on sugared treesin June.” It is not given in LeConte’s “ List of species of Eastern New Mexico,” but it is mentioned in his “ List of species of Kansas and Nebraska.” In his “New species of North Amer- ican Coleoptera,” he refers to it as “the ordinary guadrigeminata of the Southern States and the Mississippi valley.” Thus, while it is a common enough insect over a large territory, no other case of its remarkable longevity seems to have been recorded. On comparing it with the other specimens in my collection, the only decided points of difference are the smaller size of the lateral spines of the prothorax and the terminal spines of the elytra ; and the longer antennz which, not exceeding the length of the body in the other specimens, are in this one one and a-half times as long.— Ferome M’ Neil, Indiana University, Oct. 26, 1886. ZOOLOGY.! LEPTODORA IN AMERICA.—It may interest those of your readers who collect fresh-water Entomostraca to know that perhaps the most elegant and remarkable of that interesting group, Leptodora ? and Hyodon tergisus, all from the Illinois river. In our Bull. 3, é Invertebrata ecited by J. S. KINGSLEY, Sc.D., Malden, Mass, 1058 General Notes. [ December, published in 1880, it is reported as eaten by young Morone in- terrupta and Micropierus pallidus, and again by Dorysoma. In the AMERICAN NATURALIST for August, 1882, it is further report- ed from both ends of Lake Michigan and from numerous small lakes—one only half a mile wide and not over twenty feet deep. In this lake, I remember, it was rather abundant. In Cedar lake, in Northern Illinois, we took it at night with Corethra larve, but we made our most notable haul of this species in Mendola lake, at Madison, Winconsin, where we captured hundreds in the tow- ing net on a bright summer day in 1885. ft may be expect- ingly sought wherever, in permanent and rather deep water, suf- ficient numbers of the smaller soft-bodied Entomostraca occur to give it a fair chance for prey. It is not a swift swimmer, and its food must be abundant.—S. A. Forbes. BLOOD oF INVERTEBRATES.—Dr. Howell, in Johns Hopkins “Studies,” describes the blood of the king-crab, soft-shell crab, and a species of holothurian. In Limulus the blood is alkaline, quickly coagulating. It contains fine albumens which coagulate at different temperatures but which all belong to the globulin group. They resemble but are not identical with paraglobulin. Coagula- tion in the blood of Limulus results by the union of the corpuscles, and the existence of a coagulative ferment has not yet been proved. The fibrin is much like that of mammals in its solubility. zmocyanin certainly contains copper. In Neptunus (= Calli- nectes), the blood is alkaline but coagulates less quickly than that of Limulus. It contains two albumens to be classed among the globulins, and the coagulation is more complete than in the king-crab. The fibrin is very different from that of Limulus, and of it Dr. Howell says: “The difference seems to me to be too wide to suppose any close relationship between the two forms, especially as they have the same general environments ; but un- tila series of similar observations is made on the scorpion or some arachnid, we will not have sufficient evidence to make any just inferences with regard to the relationship of these forms— that is, from the standpoint here assumed.” In the holothurian, which was identified as Thyonella gemmata, two kinds of cor- puscles were recognized, a red, hamoglobin-bearing nucleated oval form and a spherical white nucleated form Coagulation © was occasioned by the fusion of the white corpuscles, the red not taking part in the formation of a coagulum except as they were entangled in the meshes of the other. . In another article in the same publication Dr. Howell notices the existence of hæmoglobin in this holothurian, the second dis- covery of this element of the blood in any echinoderm. _ coagulates at a lower temperature (56°—-60° C.) than that of ee _ brates, and is precipitated by a one per cent solution of ease - acid.

THE ByssAL ORGAN IN LEMELLIBRANCHS.’—The first portion of Dr. Barrois’ article is a very full description of the byssal organs or its remains in forms from almost every family, twenty-one in all, and in forty-nine species of lamellibranchs. There is also a historical résumé of the subject, description of additional glands, and a discussion of the homologous organs in gasteropods. In Cardium edule the organ is described in full and others are compared with it. Its parts are: 1. “The cavity of the byssus,” a large space in the center of the keel of the hatchet-shaped foot. 2. “The canal of the byssus,” opening on the surface by a . 3. “The byssus,” a hyaline thread running out from the cavity through the canal. 4. “ Byssal glands,” glandular cells lying below the epithelium and opening separately into the cavity. 5. “The groove” running forward from the canal along the margin of the foot to the anterior end. 6. “Glandular cells of the groove” opening into it among the epithelium cells. The epithelium is everywhere perfectly continuous and in the cavity is thrown into numerous lamellar folds. Various departures from the plan are described and figured; there may be no functional byssus but the other parts may all be present, or the groove, or the glands, or even the cavity may be wanting, or there may be in the adult no trace of any of the organs. In the same family or even genus wide variations may occur. Thus Tapes virginea has no functional byssus, the cavity, glands and lamellæ are present, while in Venus rudis and other lateral attachment of the creature. The “cornet” of Anomia, with its groove leading to the byssal cavity, is similar to the muciparous gland on the anterior part of the foot of Pecten maxi- | mus. In Unio and Anodontaa cavity in the keel of the foot is the only remains of the byssal organ in the adult. This, doubtless the water pore of Kollmann, Griesback and others, is lined with continuous epithelium. It is to be regretted that lack of material has prev@nted research into the embryonic condition of many of the retrograde forms. Barrois also describes as characteristic of the lamellibranchs special muciparous glands in the anterior portion of the foot s these in some cases line the inside of a cavity, e. g., Pecten maximus, in other cases the organ being everted they line the , Lille, 1885, pp. 160, pl. x. 1 Les Glandes du Pied et les Pores Aquiferes chez les Lamellibranches—Par le Dr. .

The view that the byssus of the lamellibranchs is homologous with the gastropod operculum is rejected on anatomical and histological grounds, and the muci- parous byssiparous glands are thought to correspond with the “ Lippen-drüsen ” and “ Fusshohledriisen” of Carriere, the one upon the fore-end of the gastropod foot, the other upon the creep- ing surface. The second portion of the work is a full historical and critical review of the “water-pore” controversy. No new observations of importance are recorded and the position maintained by the writer is the same as already represented in this journal (see Vol. Ill, p. 130).—Henry Leslie Osborn, Purdue Univ., Lafayette, Ind. ON THE CLASS PODOSTOMATA, A GROUP EMBRACING THE MEROSTO- MATA AND TRILOBITES.—In a paper read before the National Acad. of Sciences we have endeavored, by giving the history of the Xiphosura, Peecilopoda and Gigantostraca, to show that while the name Xiphosura should be retained for the suborder of which Limulus is the type, the names Pwcilupoda and Gigantostraca have been applied in such different senses, that they can not well be retained for the Merostomata and Trilobita taken together in the sense we advocate. We have therefore proposed the term Podostomata for this class of Arthropoda. It is derived from zoc, zodds, foot; and stéua, mouth, in allusion to the feet-like or ambulatory nature of the cephalic appendages which surround the mouth in a manner characteristic of the group. The class Podostomata may be defined as a group of marine arthropods in which the cephalic (Limulus) or cephalothoracic (trilobites) appendages are in the form of legs, z. e., ambulatory appendages, usually ending in forceps or larger claws (chele), which in the sole living representative of the class are arranged in an incomplete circle around the mouth; the basal joint of each leg is spiny, so as to aid in the retention and partial mastica- tion of the food. No functional antennz, mandibles or maxillz. Eyes both compound and simple.

The class differs from the Arachnida, among other characters, in having no functional cheliceres (“ mandibles”) or pedipalps (“maxillae”); in the cephalic appendages either ending _ in larger claws or forceps, or in being simple, the terminal joint _ not bearing a pair of minute claws or ungues like those of Arach- -~ 1886.] Zoblogy. 1061 nida and Insecta, enabling their possessors to climb as well as walk. Podostomata have no urinary tubes. Limulus undergoes a slight metamorphosis, while in trilobites the adult differs from the larva in having a greater number of thoracic segments. m the Crustacea the Podostomata differ in the lack of functional antennz, and mouth-parts; in the compound eyes hav- ing no rods or cones, in the brain innervating the eyes (compound and simple) alone; in the shape of the head and pygidium or abdominal shield, and in the arterial coat enveloping the central nervous cord. The Podostomata are divided into two orders: Xiphosura, I. Merostomata, with three suborders : p ARE urypterida. II. Trilobita. —A. S. Packard, Oyster CULTURE.—Dr. J. A. Ryder has a paper on this subject in the Report of the U. S. Fish Commission, detailing the con- struction of apparatus for the artificial culture of oysters which, from a theoretical standpoint, certainly seems practical. His plans have been outlined in this magazine, and hence need not be repeated. One of the points brought out is that Lankester’s beautifully illustrated paper on green oysters (Quart. J. M.S. XXVI, pp. 71-94, pl. vIr, 1885) contains hardly an addition to our knowledge of this phenomenon, besides the conferring of the name marennin on the coloring matter absorbed. Almost every point made was previously published by Puységur, Descaine or Ryder from two to five years before. ECHINODERM DEVELOPMENT.—Fewkes has some observations on the development of Ophiopholis and Echinarachnius. He shows that in the former genus the endoderm arises by an invag- ination, but he cannot state the relations the blastopore bears to either mouth or anus of the pluteus. The mesoderm arises symmetrically either side the blastopore and apparently is of the nature of mesenchym, though not so stated. Nothing is given concerning the development of the mesothelial tissues. Aposto- lides who has previously studied the development of Ophiurans comes in for soñe apparently merited criticisms. In the sand- dollar, Echinarachnius, the early development is much the same. The pluteus is compared with that of Strongylocentrotus, from which it differs in the presence of large pigmen t-spots on each arm and the absence of “ ciliated epaulettes.” The whole of the pluteus is absorbed in the young sand-dollar, which has a very different appearance from the adult. = e development presents bar slight differences from other echinod 1062 General Notes.

Sponges.—Dr. R. von Lendenfeld described the nervous Sys- tem of several sponges at the recent meeting of the British As- sociation for the advancement of Science. He called attention to , the fact that in the sponges the most important organs are meso- dermal (this is the case with the nerve cells) while in the Ccelen- terates proper they are ecto- or ento-dermal. On the basis of this he proposes to divide the ccelenterates of Claus into Ccelen- terata-Mesodermalia or sponges and Ccelenterata-Epithelaria or ccelenterates proper. It would seem as if these facts were an argument in favor of the view that the ccelenterates of Claus was not a natural. group, a view for which there are many other reasons for adopting. alenterates——Haddon states that his species Halcampa an- dresi is not valid but must stand as a synonym of H. chrysan- thellum (Peach) Dana.

Concerning the “yellow cells” the author states that the fact that they appear to cause a suppression of those pigments which in other Actineæ appear to discharge a respiratory function is an argument in favor of their being regarded as symbiotic alge.

Another pigment is found in the eye spots which has a spectrum bearing some resemblance to that of a red pig- ment found in the eyes of certain insects. Hickson has ob- tained the early stages of Tubipora. It is regularly holoblastic and there is an invaginate gastrula. He has also made some observations on a species of Clavularia from Celebes which go to show that this genus is closely allied to the fossil Sy1ingopora, thus adding to the evidence that the latter is an Alcyonarian The absence of special buds or gonophores to contain the sexual products of Hydra is by Professor A. M. Marshall regarded as a highly modified character due to the influence of fresh water. In Cordylophora, the other fresh-water genus, the ova develop in a zone of germination round the necks of the zodids, before either the gonophore or the branch on which it will be borne is de- veloped. Afterwards the ova migrate into the gonophore. Evidently Cordylophora is in course of suffering a transformation into sexual conditions like those of Hydra. The normal Hydroida are bisexual and develop Medusz. Echinoderms,—According to recent researches by R. Koehler, the circulatory system of the ophiurans is much like that of the Echinoidea, the same relations being found in the madreporic gland, the rings around the mouth and the branches arising from them. : Worms—A. Giard described a new Rhabdoccele, Fecampia erythroctphala, at the meeting of the Academy of Sciences of Paris, September 13. It is parasitic and forms a cocoon. Atten- tion was called to the fact that it resembles a parasite found by Lang in the foot of the mollusk, Tethys, which will probably also be found to form a cocoon. Professor W. C. McIntosh, in Nature, of September 16, thinks that Phoronis and Actinotrocha are more abundant on the British coasts than the records wo l indicate——G, Fritsch, in the Sitzungsberichte of the Berlin Academy (Jan. 28, 1886, p. 99), describes and figures the parasites of the electrical cat-fish Malapterurus.

The paper enumerates thirty species as known 1886. | Zoölogy. 1065 that region, of which thirteen are now described for the first time. Some anatomical and histological notes are given. Bell calls attention to the fact that in the land planarians the form of the head is very variable and cannot be used, as is often done, as a basis of generic division. He also states that Bipalium is sensitive to light, and if the light be too strong the specimen is killed. Collet describes (Proc. Zool. Socy., 1886) a new species of Echino- rhynchus (Æ. ruber) from Rudolphi’s rorqual (Balænoptera bore- alts). He suggests that its early stages may be passed in Æu- phausia inermis, one of the Thysanopoda. Turtonia and Cyanium are distinct, the latter genus possessing Brachiopods——Miss Agnes Crane describes (Proc. Zool. Soc., London, 1886) a new species of brachiopod (Afretia Jraziert) from Port Stephens, New South Wales. Arachnida—G, Saint-Remy, at the meeting of the Paris Academy, Sept. 20, presented the results of his studies of the brain of the spider based upon the genera Tegenaria, Epeira and Phalangium. The brains of these forms have the same general plan ‘of organization as that of the scorpion, on which a report had previously been made. Adolph Horn describes the poi- son apparatus of twenty-one species of spiders in the Bericht of the Oberhessichen Gesellschaft for 1886. The poison glands consist of two elongate cylindrical ccecal sacs enveloped in con- nective tissue and spirally arranged muscles. Their ducts termi- nate near the tips of the mandibles. Grassi describes a new arachnid in the Bulletin of the Italian Entomological Society (Vol. xvir, 1886) under the name Kenenia mirabilis. He regards it as the type of a new order, Microthelyphonida. In general appearance the form stands nearest the thelyphonids, as the name indicates. Grassi points out twenty-four points in which it differs from the whip scorpions, ` _ Ascidians—Sluiter describes fourteen new species of ascidians from Billiton island. For one of them a new genus, Styeloides, is proposed. Crustacea.—Professor C. L. Herrick gives (Bull. Denison Univ.) VOL. XX.—No. XII. 7 1066 General Notes. | [ December, an account of various stages in the development and points in the morphology of Limnetis gouldii and Chirocephalus holmani, two phyllopodous Crustacea. He also describes Wyocryptus setifer, a mud-living cladocerous crustacean. Packard describes (Proc. Philos. Soc., xx111, 380) the feet in Cryptozoe, a new genus of fossil Phyllocaridan crustacean, allied to Nebalia. The figures are too poor to show any detail, but the feet, according to the text, are much like those of Nebalia. Nothing had been known of the nature of the feet in the fossil forms before. Vertebrates.—The “ Segmental value of the cranial nerves” is treated of histologically and argumentatively by Professor A. Milnes Marshall, in Vol. 1 of Studies from the. Biol.

We are concerned here with the doctor or medicine man, who, in Australia, Africa or America, relies upon his influence and power over the spirit world to work cure or to save life. : In our own country patient study is revealing much concerning (better weather-makers), magicians, augurs, fortune-tellers, en- chanters, priests, personators, diviners, etc. Now these can readibly be divided into two classes or func- tions, viz., those who see into, understand and reveal the spirit world; and those who have more or less control over it, compel- ling it to do their bidding. € medicine man, doctor, sorcerer, wizard, fetish man are all of the latter class. Whatever disease and death may be, whether merely the person or spirit of some noxious thing or an inde- pendently existing spirit, one of the powerful charmers can in- duce or compel it to do his bidding, either by direct command or by some diplomatic action called ic. . In the collection of material for a scientific investigation of — this class of persons, I have found it convenient to adopt the fol- lowing questions: ft, What ste heacradt called and Sigs oial dank do way aad. 2.

What do they profess to do? What are they believed to be able to do? That is, to which class above named do they claim to belong ? . What do they actually perform? What is their mode of treatment? Do they sing, dance, go into ecstasy, suck the wound, spit out the disease in the form of a bone, stone, &c.? Thatis, not what they claim to do, but what do they actu- ally? What dress, paraphernalia, implements and dramatic performances do they rescrt to? What fees do they charge ? i . What is the area of their operation, both in the spiritand in the mundane world ? Some cause, others cure disease. Some have influence in one sphere, others in other spheres of spirits. Again, some operate on the sick, others on the con- jured, lovers, lost cattle, epilepsy, etc. 6. Folk-lore, beliefs and customs of the folk in view of the foregoing subjects of in- quiry. p> wt Thanks to the efforts of Mr. Howitt and others we are able to answer some of these questions concerning the Australians. “I have adopted,” says this author, “the term medicine men as a convenient title for this memoir, but the term ‘doctor’ or ‘ black- fellow doctor’ is always used in Australia for those men ina native tribe who profess to have supernatural powers. The doc- tors are magicians or wizards. I may roughly define doctors as men who profess to extract from the human body foreign sub- sfances which, according to aboriginal belief have been placed there by the magic of other doctors, wizards or supernatural beings, such as the Prewin of the Kurnai, or Ngarang of the Woiworung.” The social relations of these blackfellow doctors to the com- munity varies from tribe to tribe. In some tribes the head man need not be a wizard, but is either a very brave man or a man of influence. Among the Muning tribe the gommera is both head man and sorcerer combined. He is the éiaméian, or master of his local group. The oldest gummera is the bambian of the other gommeras. He must be gray bearded, speak several dialects and “bring things out of himself.” A vast deal of mystery surrounds the education of the doctors. Mr. Howitt narrates at full length, pp. 49-52, the story of his own initiation told by one of his friends. ; As said, the doctor and wizard are associated in function. They profess to project a quartz crystal or black stone against OF into their victim or into their own bodies, to cause magical things to enter a victim by burying them in his tracks, and on the other hand to annul the power of these introjections. These same clergy claim to know and to compel or restrain the weather (meteoroscopy or meteorocracy), to fly through the air, to T morphose themselves into animals, to be invisible and to ren persons and things invisible, to talk and associate with ghosts and familiars, to abstract a man’s fat, to discover the causes ; ath, disease or evil fortune, and finally to produce a coger _ effect upon a person by performing it upon a part te oe ‘something he has touched or held. ; er eae _ There comes out in this study the very best interpretation = 1886. | Anthropology. 1069 cotgring into them. The wizard was supposed to swing the yulo around his head and sling it at his victim. From Mr. Howitt’s language we would suppose they really take the fat from the dead and eat it, and that he really binds his living victim with the yuo, or knocks him down with the brepent, sits astride his chest, cuts open the right side below the ribs, extracts his fat, brings the cut edges of the wound together, and bites them to make them join so that no scar will be visible. We will close this note with allusion to the yenjin, a song of elopement sung by a class of wizards called Bunjil yenjin, whose Occupation is to aid in the elopement of young couples. When a young man wanted a girl whom he could not obtain from her nts, he employed one of these professionals. The latter would lie near the camp with the youth and his companions and sing a song, the others joining in the chorus. When he thought his spell strong enough he ceased, and the young folks, mem. con. would take to the bush together. : 1070 General Notes. { Decemter, THE IconoGrapuic Encycrop@p1a.—The second volume of this publication is based on von Eye’s ‘Culturgeschichte; but has a chapter on Prehistoric Archeology, by Professor Daniel G. Brinton, which doubles the value of the original work. We have no hesitation in placing this article at the head of all compendi- ums upon this subject. The method of treatment is historical. The introductory chapter is devoted to a sketch of the science and the methods and problems which have for the past quarter of a century engaged the minds of archzologists. The characteris- tics and art productions of the European age of stone in its two periods, the palzolithic and the neolithic; the age of bronze and the age of iron are treated in the first fifty pages. he prehistoric archeology of the western hemisphere is treated under the following analysis: I.

It will probably be a long time before any other author half so qualified as Dr. Brinton will try to cover the whole ground of American archeology. MICROSCOPY.! Revotvinc Automatic Microtome.—The microtome repre- = sented in the accompanying cut is the invention of Adam Pfeifer, mechanic and instrument-maker to the Biological Laboratory of the Johns Hopkins University. e machine is designed to save time and labor in the prepa- ration of series of sections, and to attain at the same time the _ greatest uniformity in the thickness of the sections. The mechanism is very simple. The frame (Fig. B) contains a horizontal screw beneath the sliding carriage (C). car- riage carries the knife (X). This carriage is moved forward by turning of screw. Two arms of the frame support the axis tj} of the revolving wheel (Æ), to which the imbedded object is attached. The knife (Æ) is clamped in an upright position on the arms rising from the sliding carriage, so that the edge of the -knife is in the same horizontal plane with the center of the axis (/). Thus, as the sliding carriage is moved by the screw, so the knife is moved to or from the revolving object. The carriage slides by means of grooves on raised tracks of the frame, and is not directly connected with the screw, but is simply pushed by nut (X). This arrangement makes it impossible that any slight eccentricity of the screw should cause a jolting of the carriage. The head of the screw is a solid wheel (M) at the end of the frame, and has 250 ratchet-teeth on its circumference. The screw has twenty threads to the inch (=.025™). The knife, therefore, is moved an inch by twenty revolutions of the screw; and as there are 250 teeth to the revolution, each tooth represents __*__ = _*_ inch (.005™"). : 20 X 250 000 The handle (O) turns the axis (/), to which is attached the wheel (Æ). This wheel is four inches in diameter, and to it is fastened the clamp which holds the object to be cut. The axis also carries a fly-wheel and an adjustable eccentric wheel (W), which is figured apart in a corner of the illustration. This eccen- tric moves a lever (Z), the long arm of which is connected with the small chain (D). The chain lifts a small lever (F), which works by means of a catch (Z) on the teeth of the screw-head, causing the screw to revolve. The small lever is steadied and pulled back to its place by a spiral spring (P), while another spring-catch underneath the frame prevents the ratchet-wheel from turning back. By properly adjusting the eccentric wheel | 7 a Edited by Dr. C. O, WHITMAN, Mus. Comparative Zodlogy, Cambridge, Mass. 1072 General Notes. . [ December, the levers may be made to act so that the catch (/) will take any desired number of teeth by every revolution of the object. The knife moves only during that part of the revolution when the ob- ject is. not in contact with the knife. The ribbon of sections slides downward from the knife and is caught on a piece of paper placed upon the table. The wheel holding the object, as well as the razor, can be moved so that almost all parts of the edge of the razor can be used. The frame bed of the microtome is made of iron, the screw ob _ Steel, and all the rest is brass. Any ordinary microtome knife or _ razor may be used, ) The machine has been in use for a year and gives the greatest — satisfaction. It can be used with great rapidity, but so far the best —— — results have been obtained at a rate of not over a hundred sec- i tions to the minute. The only possible error in a revolving of this kind is theoretical—namely, that owing to the ic : of the object, each section is part of a hoto 1886. | Microscopy. 1073 cylinder. Butin reality, with objects of ordinary size, this error is not apparent, and even under a high magnifying power there is no perceptible difference between sections cut by this microtome and those cut by ordinary slide microtomes. EMBRYOGRAPH FOR USE WITH ZeEIss MıcroscorpeEs.—This piece of apparatus, which is the work of Adam Pfeifer, the instrument- h ti f j Wa HY “ d ki i maker of the Biological Laboratory of the Johns Hopkins Uni- versity, renders the Zeiss-Oberhausen camera available for draw- ing objects under very low magnifying powers. It consists, first, of a collar fitted to the arm of the microscope, and furnished with a short draw-tube, which can be placed with the objective either above or below the arm; and second, of a vertical rod, supported a 1074 Scientific News. [December, on an arm which is clamped under the collar of the draw-tube, and carries a second movable arm resting in a collar to support the camera. This armis held in place by a thumb-screw, and it may be set at any point on the vertical rod. When the Zeiss a.a. objective is used, and the camera is lowered as much as possible, an image magnified about three diameters is projected on to the paper, and any amplification greater than three diameters may be obtained by varying the height of the camera, and by the use of the higher objectives. SCIENTIFIC NEWS. — One of the most remarkable salt formations in the world is located on the Isle of Petit Anse, Southwestern Louisiana, 125 miles due west from New Orleans. It is owned by the Avery family. This singular salt deposit is sufficiently unknown to bear the light of a more thorough investigation than it has had. The deposit is pure crystal salt. So far as it has been traced, there are 150 acres of unknown depth, explored 140 feet down. The surface of the bed undulates from one foot above to six be- low tide-level. The earth covering the salt ranges from ten to points, tomahawk heads, paint pots, mortar and pestle and_pot- tery of all kinds. The dip of the salt is eight degrees. There is a deposit of pink sandstone quite decomposed, a coal forma- tion thirteen to seventeen feet thick and seventy-two per cent carbon, the lignite cropping out a hundred feet above the sea. Over the salt come pink and yellow clay beds, then the sand- stone and then the clay, each stratum trending towards the no ere are also sulphur springs. The salt is a con- glomerate mass of crystallizations, which in the mine look like dark salt, but when exposed to the light are seen to be wai By analyses the salt is 99,48; per cent pure; the remaining 35 1S made up of sulphate and chloride of calcium. The position of the salt shows it to be older than the coal and sandstone mporary pre- 1862 while a n Davis and by a N l 1836. ] Scientific News. 1075 — Dr. Isaac Lea, the distinguished conchologist of Philadel- phia died recently at an advanced age. He was born in Phila- delphia, and during his earlier life was engaged in business as abookseller. His interest is science was however always great, and he retired from business early with a competence, and devot- ed himself to his favorite pursuit. His specialty was conchology, and in this field his publications, on both recent and extinct forms, are numerous and well known. He was for several years presi- dent of the Academy of Natural Sciences of Philadelphia, and was an honorary member of the numerous illustrious societies, includ- ing the most important scientific bodies of England, France, Ger- many, Italy, Switzerland, Austria, Belgium, Greece, India and Russia. He entertained 200 members of the British Association at his Long Branch villa in 1884. were formerly common in England. References to the belief that these animals would cause injury to the foot of man or beast over which they passed, may be found in Bell’s “ British Quad- rupeds,” and White’s “ Natural History of Selborne,” where may also be found some curious remedies for the lameness resulting.— about them by geologists, by Professor John S.
