Verbal Communications. — Professor Johnson made some remarks in relation to the apparent tendency of Anthracite coal to assume crystalline forms ; and exhibited a specimen of the rhombic form. Professor H. D. Rogers observed, that in his explora- tions of the coal formations of Pennsylvania, he found he could trace this tendency to three mechanical causes, viz : 1st. to planes of deposition ; 2dly. to transverse planes or joints ; 3dly. to faults. By special permission, Prof. Johnson in the chair, Dr. S. G. Morton made some observations on a mode of ascer- taining the internal capacity of the human cranium, by means of the tin tube and graduated rod, as described by him in Crania Americana, page 283. The materia] hitherto used by Dr. Morton for the purpose of filling the crania, was white pepper seed, which was selected on account of its spherical form, and the general uniformity in the size of the grains ; in these respects, however, there is sufficient diversity to occasion considerable variation in the results of several succes- sive measurements of the same head, especially when taken by -.-.. .ft -*►•-* 8 [April, 1841. different persons. This variation was sometimes not less than three or four cubic inches ; making it desirable to use some other bodies in place of the pepper seeds. Dr. Morton then tried leaden shot of the size called BB., measuring § of an inch in diameter ; which being perfectly smooth and spherical, of uniform size, and therefore not liable, like the seeds, to variations from packing, were found to answer the purpose in every particular. In using the shot, it is necessary to fill the skull completely, by shaking it, and by pressing the shot down with the finger and the end of the funnel introduced into the foramen magnum, until all the cavities and sinuosities are filled. When this is accomplished, the shot being transferred to the tube, will give the capacity of the cranium in cubic inches, and with so much accuracy, that in six successive measurements of the same skull, the results did not vary more than half a cubic inch ; a degree of accuracy which has not been at- tained by any former method. An experiment with the apparatus was then made, in the presence of the members, which corroborated the statements already made. Dr. Morton informed the Society, that he was now engaged in ascertaining by these means, the ca- pacity of the cranium, as indicative of the size of the brain, in the different races of men, and will report the results for publication in the proceedings of the Academy.

Mather. — From the Author. Professor Johnson offered some observations on the me- chanical structure of Coal, with evidences of the contempo- raneous origin of its various kinds. The question of the identity and contemporaneousness of the two great divisions of the coal measures of Pennsylvania, has sometimes occupied the attention of geologists. A similar question is occasionally agitated in Europe, in reference to the Anthracite and Bituminous coal fields of that quarter of the world. Among the arguments in favour of the contemporaneous deposi- tion of the coal in the two regions, those which are derived from the similarity of the accompanying measures or members of the coal series in the two regions, and the resemblance or identity of the fossil organic remains accompanying the coal in both cases, are not the least weighty. The presence of large bodies of carbonate of iron interposed among the coal beds in both coal districts, is an analogous circumstance strongly corroborative of the opinion that both varieties of coal were produced under circumstances at least strongly resembling each other. Another circumstance favourable to the supposed similarity of circumstances which accompanied the deposition of anthracite and bituminous coal, is the resemblance in mechanical structure of the two kinds. This may, at the first enunciation, seem somewhat 2 i\ 10 April, 1841.] startling ; especially since the terms heavy, hard and tough, are generally applied to the one, and light, soft and friable or tender, to the other. It is nevertheless true, that strong mechanical resem- blances exist ; and the more minutely we examine the two varieties, the more shall we be impressed with the conviction of the import- ance of the resemblance. In the first place, the coal of all coal measures has a series of partings parallel to the floor or bottom of the bed on which it rests, and to the cover or roofing under which it lies. These are as dis- tinct in inclined and vertical beds as in those which still remain horizontal. In the second place, the connection between the coal and its under- lying slate, as well as with its top slate, is so definite and well under- stood, that it serves to determine the true original position of coal beds, which have been so far disturbed as to be turned nearly up- side down ; of which examples are not wanting. These character- istics are found in beds of both kinds of coal. In the third place, there is most commonly a fracture or division of the coal in some direction (which, for the same bed, is gene- rally continuous,) and nearly at right angles to the planes of de- position. Fourth, a third series of divisions by vertical planes, called cross partings, inclined to the last mentioned. This system of planes is not always continuous throughout the bed, but varies in the differ- ent plies. The principal vertical divisions are known to miners by the names of "cleats" or " slines," and sometimes by that of "grains." The direction in which these run, seems to determine the manner of working out the coal ; for in attempting to separate large masses from their natural position by means of wedges, it is only in the direction of the cleats that the separation can take place. In in- clined beds, from which the coal is to be extracted by a slope or rail-road laid down on the floor of the bed, it is a great convenience to have the cleat lie in a direction diametrically across that of the slope, or in conformity with the strike of the bed ; for then in run- ning a drift from the bottom of the slope horizontally along the bed, and afterwards carrying the workings upward, the cleat will always face the miner, and he will be enabled to obtain heavy falls of coal by undermining and wedging down. April, 1841.] 11 In most bituminous coals, and in not a few anthracites, the "cleavage of the laminae," or what I have chosen to call surfaces of deposition, are sufficiently distinct, and afford ready partings to separate masses into small pieces. In some of the harder anthra- cites, however, these surfaces are nearly obliterated, being dis- tinguishable only by different shades of black. The actual cleava- ges of the coal, in such instances, seldom take place along the sur- face of deposition ; but on igniting the specimen, we may generally obtain partings in those natural seams. I exhibit an example in coal of Hazleton. The regular slines also, in anthracite, are sometimes so far ob- literated as to be only developed by strong heat or partial combus- tion. They are then shown by the thin, white, shining lamina? of earthy matter, which mark two opposite sides of a lump of half burnt coal. The absolute direction of the cleat is very various. At the Lau- rel Hill mines, in Hazle creek valley, it is believed to be about north 80° east. In some beds of coal which I discovered and examined on the West Branch of the Susquehanna, it is due east and west by com- pass. In the Middleton mine coal, in the Northerly part of England, it is from N. 20° West to N. 32° W. The second, or " short cleat," in opposition to the " long cleat," which extends for great distances, is the cross parting already spoken of, and not unfrequently runs perpendicularly to the direc- tions of both the " cleavage of the lamina? and to the long cleat." This is seen both in bituminous coals and anthracites. Another circumstance to which I would refer, as indicative of the similarity of origin and correspondence in character, between bi- tuminous coals and anthracites, is the correspondence of the two, in respect to the composition of the ashes of the two kinds. Silica, alumina, oxide of iron, with small amounts of lime, magnesia, and occasionally of oxide of manganese, are the ingredients of the ashes of both the kinds of coal. The proportions vary, not only in the different kinds of coal, but also in the several plies of the same bed, both in the bituminous and anthracite districts. In the anthracite, the diversity of composition is marked by the colour of the different streaks after partial incineration. 12 [April, 1S41- Another resemblance between the two kinds is that in the an- thracite beds, spaces partially vacant are found to contain masses, with a puffy aspect on the exterior, so strongly resembling coke, that it might be difficult at the first glance to distinguish a fragment of it from a piece of artificial coke. Natural coke is also found in connection with beds of bituminous coal, especially where the latter are in close proximity with primitive strata — as in the mines of Virginia. When coal contains a large proportion of earthy matter, and is deposited in thin lamince, it will, in the state of anthracite, be found to part with great difficulty in the direction of the surfaces of depo- sition. It will then be seen to give fractures, developing a multi- tude of small conchoidal surfaces, This is by the miners termed bony coal ; and that it well deserves its name may be evinced by its actually being so hard as sometimes to strike fire with steel. Coal occasionally assumes the appearance of well defined rhombic prisms and octaedra, occasionally with striated surfaces, in which cases, though the cleavages be difficult and obscure, they are never- theless practicable.

Verbal Communications. — Dr. Chaloner stated some facts contained in a letter to him from Prof. Andreas del Rio, of Mexico, in relation to an ore of Galena, containing ten per cent, of Cadmium ; of which letter a translation will shortly be presented to the Society. May, 1S41.] 15 Dr. Morton (Professor Johnson taking the chair) exhibited the embalmed body of an Egyptian Ibis, Ibis religiosa, which was unwrapped by him in the Hall of the Academy, on the 10th of April, in the presence of many members and others. This specimen was one of several sent to Dr. Morton by George R. Gliddon, Esq., United States Consul at Cairo. It was obtained at Saccara, and is probably two thousand five hun- dred years old. The bird was enveloped in nearly one hundred and fifty folds of the usual linen mummy-cloth, and was found to be in perfect preservation; the head being extended downwards between the legs, and the latter drawn up, with the toes pointing outward: the feathers were generally uninjured, retaining much of their original colour ; and it may be confidently asserted, that this is one of the most perfect examples of the art of bird-embalm- ing which has ever been submitted to the inspection of natu- ralists. The Ibis, [Ibis religiosa,) as a sacred bird, was fed and wor- shipped in the Egyptian temples ; yet it is difficult to imagine in what way they were obtained in such vast numbers as are now found embalmed in the pyramids of Saccara. For example, Pococke, who travelled in Egypt upwards of a century since, expressed a fear that the embalmed Ibis would soon become extinct, in consequence of the daily and wanton destruction of the jars in which they are embalmed ; and yet travellers of our own times assure us, after all this protracted devastation, that thousands of these relics remain undisturbed in the pyramids. The motive for worshipping the Ibis has been variously ex- plained ; but the true cause was, no doubt, the appearance of this bird (which is a native of Abyssinia) during the inundation of the Nile, and its departure to the south on the subsidence of the water; for the Egyptians rendered homage to every thing which was connected with a phenomenon on which depended all their hopes of health, plenty, and happiness. Dr. Morton adverted again to the fact, mentioned at a former meeting, that on first opening one of these Ibis-jars, the wrappings, which were beautifully adjusted, were almost, if not entirely colourless; but that in a short time they assumed the dark brown colour which the bitumen usually imparts to the mummy-cloth. 16 [May, 1841. Prof. Johnson suggested that the exterior wrappings might not have heen originally saturated with bitumen, but that they had been applied while clean to the mummy wrapped in the interior saturated folds ; and that by slow, insensible transmission, the clean folds had, with the volatilized bituminous matter, become in a manner photogenic, and capable of being turned yellow by the influence of light as soon as the jars were opened. He con- ceived this explanation of the phenomenon by the known agency of light on resinous and bituminous substances, more satisfactory than that which had been previously offered, and which ascribed it to the mere presence of air admitted on opening the jar. He suggested that the latter explanation Avouid have had more plau- sibility if the jar had really been hermetically sealed, and air tight; which,- from its texture, being that of coarse unglazed earthenware, and particularly from the covering of its mouth being a still more coarse unburnt mortar, could not be presumed to be the fact. Dr. Goddard admitted the action of light, in explaining the phenomenon in question ; but as he supposed the cloth to have been originally of a yellow or brownish colour, such as it assumes on being removed from the jar, he considered the presence of bitumen not necessary to the change. He cited, in illustration, the Cartoons of Raphael, which, having faded in a moderately lighted room, were subsequently restored to their original colours by exposure to the sun's rays. Some further observations ensued on the action of light, and its effects in bleaching resins. May, 1841.] 17 STATED MEETING, May 11, 1841. Vice President Morton in the Chair. DONATIONS TO MUSEUM.

Written Communications. — A communication was read from Dr. A. Clapp, of New Albany, Indiana, in reference to the Geological equivalents of that vicinity, as compared by him with those described in the Silurian System of Murchison. " The following fossils, which characterize the Wenlock Lime- stone of Murchison, I have found in the Limestone of the Falls of the Ohio: Favosites spongites, Retepora prisca. Acervularia Baltica, Astrea ananas? Cyathophyllum turbinatum, Syringipora reticulata, Calymene bufo. "I have also observed, at the same place, the following group of Wenlock fossils, which, however, are not characteristic of the Limestone of the Falls : Catenipora escharoides, Syringipora bifurcata, Stomatapora concentrica, Favosites C4othlandica, Turbinalapsis bina, Strophomena euglypha? Atrypa prisca. To Avhich I may add the following fossils of Goldfuss, which are not found in the Wenlock Limestone, and some of them not even in Wales: Cyathophyllum ceratites, C. vermiculare, and C. helianthoides, Stomatopora polymorpha, Favosites polymorpha, and F. basallica, Gorgonia infundibuliformis? the last being more common in the latter formations. (Ludlow.) Besides the preced- ing species, I have many Polyparia, and some shells of the Falls Limestone yet undetermined. In the Limestone and Marls of Madison and Hanover, in Indiana, I have identified two other species belonging to the Wenlock shale, viz.: Terebratula spherica? and Orthocera eccentrics. The middle and lower strata of the Blue Limestone and Marls at Cincinnati, and the lowest at Madison and Hanover, appear to be equivalents of the Caradoc Group of Murchison, and contain the following fossils: Orthis callactis, Calymene punctata, C. Blumenbachii, Triarthus Beckii, Isotelus — , Pentacrinit.es prisca, (Goldf.) This formation has very few Polyparia, but many shells, which are different from any described by Goldfuss or Murchison. " The black bituminous slate that overlies the limestone at the May, 1841.] 19 foot of the Falls, and is found in many parts of the western coun- try, is probably the equivalent of the Marcellus Shale of New York. This is an excellent landmark, as there is no other for- mation in the west that can be easily mistaken for it. The situation of this slate at the Falls has been misunderstood in some instances, and described as underlying, or beneath the limestone. "The dividing line between the upper and lower Silurian groups, (Wenlock Shale and Caradoc rocks,) appears to have no distinct lithological demarcation in our western formations; yet this line will probably be found to occur in the upper series of the Cincinnati and Madison Blue Limestones and Marls." Mr. T. A. Conrad submitted a description of three new species of Unio, from the rivers of the United States, viz.: 1. Unio perplicatus. — Obtusely subovate, very ventricose; rather thick, with about 12 oblique, profound plica?, those behind the umbo recurved ; ligament margin greatly elevated ; posterior superior margin slightly concave, oblique, extremity truncated ; epidermis blackish-brown, apex erobed ; within tinged with purple; cardinal teeth direct, prominent, sulcated. (Length 2.4; height 1.3; diameter 1.9.) This species is most nearly related to U. costatus, (Raf.) but differs in being far more ventricose, and has very prominent urn- bones, which are just the reverse in the costatus. The diameter through the umbonial slope is profound. 2. U. nodiferus. — Obtusely subovate, ventricose, moderately thick; surface with a few nodules about the middle of the valves, and smaller ones near the ligament margin ; a slight, not very wide, furrow extends from beak to base; posterior margin approaching to a regular curve; beaks eroded; within white ; cardinal teeth robust, prominent, direct, and profoundly sulcated in old shells; epidermis chestnut-brown. (Length 2.1, 1.8; height 1.1, 1; diameter 1.6, 1.4.) Approaches U. prasinus, but differs in being proportionally longer, more convex, in having a brown epidermis, narrower anterior side, and oblique posterior margin. 20 [May, 1841. 3. U. paralellus. — Oblong1, sub-rhomboidal, convex, moderately thick, slightly contracted from beak to base ; hinge and basal margins parallel, nearly rectilinear; posterior margin oblique; extremity obtusely rounded; epidermis dark olive-brown; within white; cardinal teeth oblique, double in each valve ; cardinal area under the beaks almost obliterated. (Length 3.7; height 1.1; diameter 1.8.) Some' conchologists may consider this to be a variety of U. purpureus, (Say,) and as but one specimen has been received, I cannot judge of the amount of difference which will obtain be- tween the two species. I think the purpureus has never yet been found nearly so far south-west as Louisiana; certainly, after a long examination of the waters of Alabama, I was unable to find it. The paralellus differs from purpureus in having a white interior, in the obliteration of the cardinal area, in the regular convexity of the valves, and in having a much larger accessory muscular impression. These three species are in the collection of the Academy: they were sent from Jackson, in Louisiana. STATED MEETING, May 18, 1841. Vice President Morton in the Chair. DONATIONS TO MUSEUM.

The sample of coal, of which the following is a description? was collected by Mr. J. F. Watson, of this city. 22 [May, 1S41. In exterior appearance it is nearly related to many of the richest bituminous coals of this country and of Europe. It is moderately compact ; thin shining lamina? are seen parallel to the bed or plane of super position, but the greater part of the mass is of a dull or pitchy black colour. Its horizontal or depository surfaces are rather uneven ; vertical sections in some p^rts smooth, in others, irregular; very little indication of reediness is perceived. Portions of "clod" or vege- table charcoal are occasionally met with. Its specific gravity is 1.324. At a temperature of 300° Fah. it loses of water 2.2 per ct. Coked at a bright red heat it gives off of volatile matter, burning with a brilliant flame, 27.8 " It contains of carbon, not volatile by simple heat, 67.62 " And when fully incinerated, leaves of reddish grey ashes 2.33 " 100. On being quickly exposed to a full red heat it becomes com- pletely fused, and the original form and structure are entirely lost. The coke accordingly belongs to that class which has received the designation of "highly bituminous coal coke." Carbon, Vol. matter. Ashes.

Helix Bidentifera. — Testa convexa, depressa, corneo-lutea ; regu- lariter et tenuiter striata, striis longitudinalibus, obliquis ; umbi- licata, apertura compressa ; labro subreflexo, duobus dentibus albis, rotundis, parvulis, in margine inferiore, instructo. Shell much depressed, rather thin, epidermis yellowish horn colour shining ; whorls six, rounded, with very numerous, raised, oblique striae ; suture strongly impressed ; aperture compressed, con- tracted by a groove behind the outer lip ; outer lip moderately reflected ; within the edge of the aperture on the lower portion, two fine rounded white teeth, one near the umbilicus, the other nearly equidistant from the extremities of the outer lip ; umbili- cus round, of moderate diameter, not encroached on by the outer lip, well defined and deep ; base rounded, more convex than the 28 [JUNE, 1841. upper surface, transverse diameter 2-5 of an inch, height 1-6 of an inch. Brought from North Carolina by Mr. T. Nuttall. This shell differs from all the known American Helices, in the character of the two minute, well defined teeth on the outer lip, while it is without a trace of a tooth on the pillar lip. Helix lasmodon. Testa subelevata, centiculata, crassiuscula, urn- bilicata, substriata ; apertura compressa ; labro acuto, uno vel duobus dentibus lamellosis ; base rotundato ; colore albo corneo. Shell moderately elevated, lenticular; rather thick; epidermispale whitish horn colour, smooth, shining ; whorls eight, very faintly and obliquely striated ; suture indistinct ; aperture compressed, within a broad calcerous deposit, and one or two lameller teeth following the direction of the whorls ; lip acute ; umbilicus mod- erately large, rounded and deep ; base regularly rounded into the umbilicus. Transverse diameter 7-20, height 3-20 of an inch. Brought from Alabama by Dr. W. Blanding. This shell resembles no other American species but H. suppressa Say, and H. gularis Say, and from these it differs decidedly in the well defined and deep umbilicus ; it differs from H. Epistilium, in the smaller size, greater number of whorls, large umbilicus and lentic- ular form. Mr. T. A. Conrad read a paper descriptive of twenty-six new species of Fossil shells, discovered by him in the Medial Tertiary deposits of Calvert Cliffs, Maryland, viz. : Venus. Venus latilirata. — Trigonal, convex depressed, ribs concentric, about 5 or 6 in number, flattened, reflected, irregular, one of them generally very wide ; ribs irregularly sulcated on the pos- terior slope ; inner margin finely crenulated.

Allied to I. trochiformis, Lam. but is less variable in form, and has larger spines. FlSSURELLA. Fissurella Marylandica. — Elevated, with numerous striae, alter- nated in size and minutely granulated by fine crowded concentric lines crossing them ; foramen large, regularly oval. Length 1 inch. Closely allied to F. Griscomi, but is readily distinguished by a much larger foramen, finer concentric lines, in not being late- rally compressed, &c. Dispot^ga. Dispotaea ramosa. — Suborbicular, with broad prominent ribs, and radiating, ramose, wrinkled and highly ornamental striae ; mar- gin profoundly indented by the projecting ribs. Width 1 3-8 inch. This species has been confounded with D. costata, but the ramose lines give it a very distinctive character. Occurs on James River, Virginia. Cancellaria. Cancellaria biplicifera. — Turretted, with thick longitudinal ribs, and spiral rather distant impressed lines ; on the body whirl an occasional intermediate fine line ; space below the suture widely and deeply channelled; shoulder coronated ; umbilicus small ; columella concave, and with two plaits.

Length 2 1-2 inches. Height the same. For this splendid Cardium, I am indebted to my distinguished friend J. N. Nicollet. It was found in green clay at 50 feet in height on the right bank of the Washita river, Monroe county, Louisiana. Fusus. Fusus pachyleurus. — Fusiform, thick, with spiral striae not very distinct ; whirls of the spine concave above, convex, and with obtuse ribs below, except upon the lower whirl which is entire ; body whirl also destitute of ribs, abruptly rounded or subangu- lated at base, ventricose ; beak long, thick, straight ; labium widely reflected; channel contracted. Length 2 1-2 inches. Presented by Mr. Nicollet : it is from the Lower Tertiary of Alabama. Professor Johnson made some remarks on the magnetic phenomena attending the congealing of cast-iron. 6 34 [June, 1841. To observe the time and degree of rapidity of resuming the mag- netic power by a mass of melted iron, a bed was formed about 3 or 3 1-2 feet in length, 5 inches deep, and of the usual form for cast- ing pig iron ; rounding at the bottom and 4 or 5 inches broad at the top. The length of this bed was nearly in the direction of the magnetic meridian. A compass needle 3 inches long was placed near the northern end of the bed, but a little to the east, and about 5 inches short of the extremity ; another needle about 7-8 of an inch long, was placed symetrically to the west side of the bed, and about the same dis- tance from its southern extremity. Thus a line joining the centres of the needles, would pass over the centre of the pig bed, and be about nine or ten inches shorter than the latter. The needles having come to rest, and their positions been noted, the bed was filled with melted iron. A slight derangement of the needles occurred while the ladle was near, during the pouring of the metal ; but they soon recovered their previous position, as soon as the ladle had been removed. They were then carefully watched in order to detect the first movements which should occur after the solidifying of the pig. At the end of 20 minutes the metal being cooled down to a heat which made it barely red in daylight, the first movements were detected, slow and scarcely perceptible, but increasing in rapidity so that at the end of two minutes, the divergency amounted to 8° ; in 4 minutes it had extended to 20°, the pig being nearly black ; and in 20 minutes more, the divergency had attained its maximum of 22° from the original position. As the influence of the earth's magnetism converted the northerly part of the pig into a north pole, it of course repelled the north pole of the needle placed near it, and attracted the south. The reverse taking place at the oppo- site end of the pig, the north end was there attracted and the south repelled. To ascertain whether any degree of permanent magnetic force would be retained by the pig, it was thrown from its bed and caused to make one-fourth of a revolution horizontally, so as to bring its longest diameter into the magnetic east and west. In this, position it exerted no power on the needle brought near either June, 1841.] 3f> extremity, but on reversing its position in the bed the end which had before been a north pole was made a south one ; and vice versa . Dr. Morton made some remarks on the Ancient Peruvians ; that extraordinary people who preceded the Inca race, and whose monuments show a remarkable advance in civilization at a very early epoch. " In my work on American skulls (Crania Americana,) I have expressed the opinion that the heads of the ancient Peruvians were naturally very much elongated ; and that they differed in this respect from those of the Inca Peruvians, and other surrounding nations ; and having given this opinion at a meeting of the Acade- my prior to the publication of my work, I take this occasion to renounce it. In the American Journal of Science, for March, 1840, I have already, in a brief note, adverted to this change of opinion ; and I now repeat my matured conclusions in connection with positive facts, derived from the work of a distinguished traveller and natu- ralist, M. Alcide D'Orbigny. This gentleman not only visited the elevated table-land of the Andes, which was once inhabited by the ancient Peruvians, but he remained a long time in that interesting region, and has collected numerous facts in relation to the people themselves. 1. The descendants of the ancient Peruvians yet inhabit the land of their ancestors, and bear the name of Aymaras, which was pro- bably their primitive designation. 2. The modern Aymaras resemble the surrounding Quichua or Peruvian nations, in colour, figure, features, expression, shape of the head, (which they have ceased to mould into artificial forms,) and in fact in every thing that relates to physical conformation and social customs ; their languages differ, but even here there is a resemblance which proves a common origin. 3. On examining the tombs of the ancient Aymaras, in the envi- rons of the lake Titicaca, M. D'Orbigny remarked that those which contained the compressed and elongated skulls, contained also a 36 [June, 1841. greater number that were not flattened ; whence he infers that the deformity was not natural, or characteristic of the nation, but the result of mechanical compression. 4. It was also remarked that those skulls which were flattened were uniformly those of men, while the heads of the women always retained the natural shape, — the squared or spheroidal form which is characteristic of the American race, and especially of the Peruvians. 5. The most elongated heads were found in the largest and finest tombs ; showing that the deformity was a mark of distinction among these people. 6. The researches of M. D'Orbigny confirm the statements made at distant intervals of time by Pedro de Cieza, Garcilaso de la Vega, and Mr. Pentland, and prove conclusively, what I have never doubted, that these people were the architects of their own tombs and temples ; and not, as some suppose, intruders who had usurped the civilization, and appropriated the ingenuity of an ante- cedent and more intellectual race. M. D'Orbigny found temples from 100 to 200 metres in length, facing the east, and ornamented with rows of angular columns ; enormous gateways made of a single mass of rock, and covered with bas reliefs ; colossal statues of basalt ; and large square tombs, wholly above ground, and in such numbers that they are compared to towns and villages. My published observations go to show that the internal capacity of the cranium, as indicative of the size of the brain, is nearly the same in the ancient and modern Peruvians, viz. about seventy-five cubic inches, a smallness of size which is without a parallel among existing nations, excepting only the Hindoos. M. D'Orbigny even supposes the ancient Peruvians to have been the lineal progenitors of the Inca family; a question which is not led Supposing this to be the fact, we may inquire how it happens that the Incas should have so entirely abandoned the prac- tice of distorting the cranium ; especially as this, among the Ayma- ras, was an aristocratic privilege ? I was at first at a loss to imagine how this singular elongation of the head was effected ; for when pressure is applied to a spheroidal June, 1841.] 37 head, as in the instance of the Chenouks and other tribes of the Columbia river, the skull expands laterally in proportion as it is depressed above ; whereas, in these people, the head is narrow from the face to the occiput. It seems probable that this con- formation was produced by placing splints or compresses on each side of the head- from the cheek bones to the parietal protube- rances, and another on the forehead, and confining them by rotary bandages. In this way the face, in the process of growth, would be protruded in front, and the head elongated backwards; while the skull, in all other directions, could expand comparatively little. These remarks will be more readily understood by reference to the annexed outlines, which are taken from a cast of one of the skulls obtained by Mr. Pentland. Dr. Goddard suggested that the deformity observable in this series of crania, might have been produced by the action of rotary bandages alone, without the use of splints or compresses. Dr. Morton admitted the possibility of this result in some of the heads, but thought that in others there was satisfactory evidence of the use of the splint or compress, especially on the os frontis. 38 [June, 1841. Dr. Morton exhibited, in further illustration, six casts of heads and three skulls of these people, all of which present the elongated form in question. For further details Dr. Morton referred to his Crania Americana, and to the beautiful and instructive work of M. D'Orbigny, entitled " L'Homme Americain, considere sous ses rapports physiologiques et moraux." These works were at the same time placed on the table for inspection and comparison.

Verbal Communications. — Mr. Clay remarked that on ex- amining a series of magnesian minerals recently received by him from Europe, he finds that four species which are describ- ed as new, and perhaps a fifth, exist in the United States, but do not appear to have been hitherto recognised by our mineralogists. These species are Agalmatolite, Kerolite, Pic- rosmine, Picrolite and Metaxite. (Breithaupt.) Mr. Clay thinks that all these minerals (of which, however, he regards the two last as doubtful species,) except Picrosmine, are found in Chester and Delaware counties, Pennsylvania. Mr. Clay pro- poses to investigate this subject more in detail. Dr. Blanding mentioned some facts in relation to the sur- prising fecundity of the striped Bass, Labrax lineatus. He obtained one of these fish which weighed 65£ lbs. and the roes 4 lb. 6 oz. 2 dr. He found one hundred of the eggs to weigh a grain and a half; and although one end of the con- taining membrane had been ruptured, whereby some hundreds were lost, the whole number of eggs must have been at least 2,248,000. NEW BUSINESS. The committee appointed at a former meeting to wait on Mr. Rembrandt Peale in reference to a portrait of the late Mr. Thomas Say, ordered by the society, reported that the same was now completed, and would shortly be suspended in the Hall of the Academy. 40 [June, 1841.

Prof. Johnson. Written Communications. — Professor Johnson submitted the result of his experiments " On the relation between the coal of South Wales and that of some Pennsylvania anthra- cites." Having received some time since a number of samples of the coals used by Mr. Crane at the Yniscedwyn iron works in South Wales, some pains have been taken to trace the relation of that mineral to some of the many varieties of anthracite found in Penn- sylvania. It was the first step in this inquiry to mark the relation June, 1841.] 41 by external characters. These in the Welsh coal are, 1st. A struc- ture often lamellated, and tending to separate on the surfaces of deposition, owing to the quantity of carbonaceous clod which occu- pies the dull seams between the bright plies of coal. 2d. The abundance and width of the reeds constituting the char- coal deposits. 3d. The shining and polished surfaces occasionally presenting themselves to view at some of the natural partings. 4th. The purplish tints of metallic oxide often observable on the surfaces of fracture. 5th. The general colour is deep black, and either dull or shining according as the ply which is examined belongs to the coal proper, or to the carbonaceous clod partings of the seams. The next circumstance worthy of attention in tracing the relation of coals, is their specific gravity; and this in the Welsh anthracite is from 1.336 to 1.372, not greater than that of many bituminous coals. The next circumstance worthy of attention is the quantity of volatile matter, and this by the mean of two trials is 9.18 per cent.; that on the anthracite containing most clod is 10.7, and that of the more compact variety is 7.66 per cent. Mr. Mushet makes it from 6.66 to 7.80 in the coals of the same locality. Mr. Frazer analyzed a sample of the same coal, and found 7.60 of volatile matter, 86.6 of carbon, and 5.08 of ashes. The quantity of earthy matter in the Iniscedwyn anthracite, according to the mean of 3 analyses of Mr. Mushet, is 3.578 per cent. Adopting this for the proportion in the sample which yielded 10.7 per cent, of volatile matter, we have the solid carbon = 85.722 per cent, and in the other 88.762. Among the Pennsylvania anthracite, that which according to the observations of Prof. Johnson approximates most nearly to the Inyscedwyn coal, is the coal of Lyken's valley, situated in the northwestern fork of the southern coal field. This coal has all the exterior characters of the Welsh anthracite ; containing in many samples a large portion of carbonaceous clod, with well marked 7 42 [June, 1841. vegetable impressions; and in colour, structure, and varieties of sur- face, the two coals might readily be taken the one for the other. Of nine samples analyzed by Prof. Johnson, the lowest specific gravity was found to be 1.374, the highest 1.416, and the mean 1.390. The mean amount of volatile matter was found to be 8.067, the highest being 11.854 per cent. ; the mean proportion of earthy matter and metallic oxides is 4.46 ; and that of the fixed carbon 87.472 per cent. From these data we derive the following comparisons. Sp. Gr. Vol. mat. Carbon. Ashes Inyscedwyn, lighter variety, 1.336 10.7 85.722 3.578 Do. heavier, 1.372 7.66 88.762 3.578 Mean of two, . = 1.354 9.18 87.242 3.578 Ly ken's valley, . 1.390 8.067 87.472 4.460 In distilling the Welsh anthracite, the first portion of gas which comes over, burns with a pale blue flame, like that of carbonic oxide, which is succeeded at a certain point of temperature by a sudden outburst of carburetted hydrogen, burning with a bright flame and some smoke, a quantity of bituminous matter being at the same time evolved ; sufficient in one instance to close up the narrow beak of the retort employed in the distillation. The coke is perfectly anthracitous, and the angles of the fragments entirely sharp and well defined. The gaseous matter of the Lyken's valley anthracite also burns with a brilliant flame, but no violent explosive development of it was remarked. Professor Johnson made some remarks on the recent appli- cation of Anthracite, to the smelting of the magnetic, iron ores of New Jersey. This has been effected at Stanhope, on the line of the Morris canal, 38 miles north-east of Easton, at which one furnace is now June, 1841.] 43 in action ; another is nearly completed, a third is partly finished, and the foundations of a fourth are prepared. The ore used at those furnaces is mined at Irondale, 7 miles eastward of the works, on the line of the canal, and is found to yield in practice 65 per cent, of pig metal of a lively grey colour, soft, and easily wrought, though not remarkably tough. The an- thracite hitherto used is that from the Lehigh, chiefly from the middle coal pit, and according to their experience hitherto, a decid- ed preference is given to the Beaver Meadow coal. The hot blast is employed at a temperature of 600 degrees and upwards. The quantity of coal required within the furnace to make one ton of iron is 22 cwt. ; that for heating the blast, about 4 cwt. The air is delivered to the furnace under a pressure of 3 lbs. to the square inch. The amount of blast furnished by the engine is 4071 cubic feet per minute ; which as the furnace makes 8 tons per day, gives a little more than 25 tons of air urged through the bellows for every ton of iron produced. But the air heating ovens are supposed to receive about one tenth of this amountv and nearly an equal portion is believed to be wasted through apertures in the tubes leading to the engines. If this estimate be correct, the quantity of blast actually delivered to the furnace will be 20 tons per ton of pig metal produced ; a quantity corresponding with what has been found necessary both from theory and from experience in other anthracite furnaces. 44 [June, 1841.

A letter of similar import was also read from Dr. J. P. Durbin, of Dickinson college. June, 1841.] 45 Verbal Communications. — Dr. B. H. Coates stated, that out of about 20 stalks of bearded wheat, which he had recently examined in Moyamensing, and which were selected as not having been able to develop their seeds, the greater part pre- senting the appearance called smut, he found all but two to have the aspect of having been stung by insects, in the first or second joint, generally the first. In all but four, the resem- blance of a sting appeared to penetrate the cavity of the straw, and the inside had the appeara nee of having been eroded, with a perforation extending to the outside. Opposite to two of these, on the outside, and under the sheaths of the first and second joints, he found puparia, resembling those of the familiar Ceci- domyia of Say. One of these was empty ; and the separa- tion of the leaf sheath from the stalk, with a black streak, pointed out a route by which the animal could have escaped. These cases last enumerated corresponded with the verbal communications of Miss M. A. Morris. On the outside of another basal stipule of wheat, he found two quiescent animal bodies, whitish, with dark spots, having much of the general appearance of what is considered by Mr. Say, the larva of the Cecidomyia. One of them in 24 hours became of a pale brown and shrivelled ; and in two days more developed a dipterous fly, which farmers said they should have classed among the common destroyers of the wheat, and which was exactly of the size of Say's figure, measuring 3-20ths of an inch in length ; but was of a paler colour, and had setaceous antennse. Its general aspect resembled that of a tipulide fly. After a partial inspection by a gentleman who had bestowed much labour on Entomology, the impression was received that it did not belong to the genus Cecidomyia; and the specimen is kept for accurate examination. Professor Johnson drew the attention of the society to the atmospheric phenomena attendant on extensive conflagration ; and stated on the authority of Dr. H. King of Washington 46 [June, 1841. city, that the burning of the prairies in Wisconsin and Mis- souri, is frequently, and almost immediately followed by rain. This observation had been confirmed to Dr. King by other observers ; and in the western country it had become a popu- lar impression that a prairie-fire was the forerunner of rain. Dr. Coates had met with a statement in Nichols's History of Leicestershire, which bore on the same question; viz. that in the reism of one of the Stuarts, orders were sent to a sheriff of Staffordshire to discontinue the burning of Ferns during a Royal progress, because the operation was usually followed by rain. Mr. Phillips adverted to the memorable hail-storm which occurred immediately after the last great fire at Constantino- ple ; the fact being fully authenticated by Mr. Walsh and Commodore Porter. That rain is common in South America after the burning of the Pampas, is familiar to meteorologists ; and the attention of the members is especially solicited to this inquiry, in order that a more extended series of facts may be collected and compared. MEETING OF BUSINESS, June 29, 1841. Vice President Wetherill in the Chair. REPORTS. The Corresponding Secretary read his report for the last month, which was adopted. The Botanical Committee made the following report, which was ordered to be printed in the Society's proceedings. June, 1841.] 47 Hall of Academy, June 22d, 1840. — The Botanical com- mittee having examined the collection of plants lately presented to the Academy by Wm. Hembel, Esq., (being that portion of the Herbarium of the late Prof. C. S. Rafinesque containing the specimens from which the descriptions in his Medical Flora have been made, together with other valuable European and Oriental plants,) respectfully state, that they have found them in good condition, and have accordingly proceeded to incorporate them with the Herbarium of the Academy. They suggest therefore that the thanks of the Society be presented to Mr. Hembel for the same. On behalf of the Committee, R. Bridges, W. S. Zantzinger, G. Watson. The Botanical committee reported that the portion of the Society's Herbarium placed in the hands of Drs. Torrey and Gray, of N. Y., for arrangement, has been returned, not only in good order, but much improved by the addition of notes, in the form of names, with references to the Flora of North America, by Messrs. Torrey and Gray. The committee on Mr. Conrad's paper on " New Species of Medial Tertiary and other Fossils of the United States," re- ported in favour of publication. Dr. Morton announced that, agreeably to appointment, he had prepared a Memoir of William Maclure, Esq., late Presi- dent of the Academy ; whereupon it was on motion, Resolved, That Dr. Morton be requested to read the said Memoir on Thursday evening next, July 1, at 8 o'clock ; and that the scientific bodies of the city be invited to attend. Resolved, That the Memoir be read in the Hall of the Academy, and that a committee be appointed to make the necessary arrangements. 48 [June, 1841.

Verbal Communications. — Dr. Morton (Prof. Johnson taking the chair,) made the following communication. " I submit to the inspection of the members eight skulls of the ancient Mexican race, for six of which 1 am indebted to Don J. Gomez de la Cortina, and for the other two to Dr. John P. Macartney of the city of Mexico. All these crania have been received since the publication of my Crania Americana. The skulls are of the following nations. 1. Otomies. — Four in number, with the high vertex, flat occiput, July, 1841.] 51 great lateral diameter and broad faces, characteristic of the American race. The Ottomies preceded the Tolticas, and were the least cultivated of the demi-civilized nations of Anahuac. The lam-est of these heads gives 92 cubic inches of internal capacity ; the smallest, that of a female, only 67. 2. Chechemecan. — A single skull, of 83 cubic inches of internal capacity. This nation followed the Toltecas in the possession of Mexico in the 11th century of our era. They were nomades and hunters, but rapidly acquired the arts and civilization of their predecessors. 3. Tlascalan. — A single cranium. These people formed one of the seven tribes who established themselves in Mexico during the Chechemecan monarchy, and are renowned in history for their warlike exploits. They are well known to have rendered Cortez essential aid in taking the city of Mexico. This skull gives an internal capacity of 84 cubic inches, and like the others of this series, is remarkable for its diameter between the parietal bones. It is worthy of remark that the average internal capacity of these six authentic Mexican skulls, is precisely what I have accorded to these people in my Crania Americana, viz. seventy-nine cubic inches. The mean of the facial angle also accords with my previous measurements, and gives 75°. All these heads were obtained from tumuli or mounds, within the territories of the nations whose names they bear, so as to leave no doubt in the mind of the distinguished gentleman from whom I received them, of their having pertained to individuals of those nations. The two remaining crania are supposed to be those of Aztecks, who also belonged to the confederacy of the seven tribes, but were the last to take possession. These were the people who subse- quently obtained the supreme power, and under the name of Aztecs or Mexicans, governed the country at the epoch of the Spanish inva- sion, a. d. 1521. The Aztecks were a brave and intelligent people, but remarkable for bloody rites, both in their warlike and religious observances. They were less cultivated than the Toltecas, but 52 [July, 1841. much more so than the surrounding barbarous tribes ; and appear, in fact, to have been the connecting link between the two. The largest of these heads gives 85 cubic inches of internal capacity ; the smallest 77 ; the medium being 80 cubic inches. The configu- ration of these heads is on the same model as the preceding series, and the mean facial angle differs but a single degree. Whoever will be at the pains to compare this series of skulls with those from the barbarous tribes, will, I think, agree that the facts thus derived from organic characters, corroborate the position I have long maintained, that all the American nations, excepting the polar tribes, are of one race and one species, but of two great families, which resemble each other in physical but differ in intel- lectual character."

A letter was read from Dr. Goheen, dated Monrovia, Africa, April, 8, 1841. Dr. Goheen gives some interesting facts in reference to the natural history of this region, and suggests the importance of sending competent naturalists to explore its numberless and extraordinary productions. A letter was also read from Professor John Locke, of Cin- cinnati, Ohio, in answer to the announcement of his election as a corresponding member. Verbal Communications. — Mr. S. S. Haldeman communi- cated the following facts in Ornithology. 1. Falco peregrinus. — It is asserted in the works on American Ornithology, that this bird builds its nest on trees, and not in the clefts of rocks, as in Europe. So far as my observa- tions have gone, this remark is incorrect, inasmuch as they build in the cliffs which border the Susquehanna. This species remains in Pennsylvania ten or eleven months of the year. 2. Quiscalus versicolor. — Mr. Swainsonin the " Menageries," (p. 298 of the Cabinet Cyclopaedia.) describes the female of this bird as a new species, under the name of Q. purpuratus. I have shot the male and female together, carefully com- pared them with his descriptions, and confidently assert, that they belong to one and the same species. 3. Anser hyperboreus. — I have known but a single individual of this species to occur on this part of the Susquehanna river, (50 miles above tide water.)

Cygnus Americanus. — Many flocks visited this part of the Susquehanna about 15 years ago, during a continuance of foggy weather, but they have not since appeared. Dr. Coates exhibited specimens of larva? from the hollow of the straw of wheat, in the upper joint, obtained from a locality near Germantown, in which they were stated to be numerous. July, 1841.] 55 No pupa) were observed by the collectors of these specimens in the same plants, other than those of the common appearance ascribed to Say's insect, and near the roots. None other were found in the present straw, after a careful examination. Other remarks were made, on the probability of several ani- mals, not all yet identified, infesting the wheat in Pennsylva- nia; on the beauty, learning and careful preparation of Mr. E.C. Herrick's recent memoir ; on some interesting observations of that gentleman ; on the effects of climate in varying the kinds and diversity of destructive insects ; and on the influence exerted by the age of the plant over the selection of a point of deposit for eggs. Dr. Coates in addition to a former verbal communication, had observed the following. Larvae apparently similar to those above mentioned, in Blockley. A body nearly the size of Say's pupa, of a pure, homo- geneous straw colour, immersed in a depression of the straw, beneath a pupa of the appearance of Say's, and having, lower down than either of them, a round perfora- tion extending into the hollow of the straw, with this cavity eroded on the inside ; all from the third joint. This body subsequently assumed markings, having the appearance of the separation of a head, cases for antennae, and other organization. Though this appearance of development took place, and the subject was kept from June 23d to July 9th, no fly had as yet been produced. A very active larva, supposed to be of a lepidopterous ani- mal, ll-20ths of an inch long, colour reddish black, with three yellow streaks throughout its whole length, three anterior feet clawed, and it is believed some of the posterior ; the animal imperfectly observed from a wish to leave it but little disturbed. Found in Blockley, June 23d, in the hollow of a wheat straw; a round hole through which it could have entered, penetrating the cell in which it was feeding, and also the leaf-sheath with- 56 [July, 1841. out ; preferred its own cell to a fresh one ; devoured a part which was quite dry ; about July 4th or 5th, closed the open- ing of its cell with a mixture of dust of straw and a cement, and besmeared it throughout great part of its extent with a black substance ; remained quiescent and apparently feeble till July 7th ; and between the 7th and 9th escaped, leaving a hole of sufficient size for its passage in the paper cover of a bottle, and no visible skin in its former abode.

A letter was also read from Prof. Del Rio, of the city of Mexico, enclosing a communication from Mr. Joseph Mur- guitro, describing a new mode of mining and blasting rocks. Referred to a committee consisting of Messrs. Chaloner, Booth and Lukins. Dr. B. H. Coates stated that Miss Morris had seen a Tipu- lide fly in the act of placing her eggs on or in a grain of wheat. This fly and these eggs she had in good preservation. On comparing it with Le Sueur's drawing, she could see no difference, except that the antennae were not quite so long, and that the small nerves of the wings were more clearly defined and strongly marked. She had also found a flaxseed pupa in the cavity of the straw, with no hole, crack or visible mark where the larva could have entered. This pupa she has exa- mined with a microscope, and she can detect no difference in it from that on the outside. This too she has carefully pre- served. These important facts and specimens may, in the conviction of Miss M., either prove her previous views correct, or that there are two species of this destructive pest. Mr. Phillips submitted the following memorandum, which was read and ordered to be printed in the Society's proceed- ings. In consequence of inquiries from different persons of the date of publication of the papers in the early volumes of the journal of this Institution, I have searched for the numbers as published with their original envelopes, bearing the date of the month of publica- tion, and have been so successful as to find a complete series. As the covers of the numbers are thrown aside by the binder, and very few sets of the journal remain in their original form, I have pre- pared a list of the dates, in order that naturalists may be at no loss 9 58 [July, 1841. in future to determine the claim of originality to descriptions of species, by the rule now most generally admitted, viz. priority of the date of publication.

H.Coates, submitted the following "Observations on the development of the Hes- sian Fly," dated August 6, IS41. "Having completed a series of observations on an insect that has for years destroyed the wheat in the neighbourhood of Phila- delphia, I now beg leave to lay them before the Academy of Natural Sciences, with specimens of the insect in all its forms, from the egg to the perfect fly. To those familiar with Mr. Say's description, accompanied by Mr. Le Sueur's accurate drawings, given in the first volume of the Journal of the Academy, no doubt can arise as to the identity of the male insect now presented with the Cecidomyia destructor of Mr. Say; but the female differs materially in colour, her body being entirely black or blackish- brown ; and the wings are destitute of the hairy fringe so con- spicuous in the male. In the months of March, April and May, I have frequently found the larva? feeding in the centre of the straw, from the root up to above the last joint. They were then of a pale greenish white colour, translucent, with an internal visceral green line ; mandibles of a dark brown colour. At this early period the larva? have frequently been so small that a magnifying glass has been necessary to detect them, In the present year, 1841, my observations were unavoidably delayed until the first of June ; when I found that the larva? near the root had left the inside of the straw, and become pupa? on the outside, under the sheath. On the 20th of June, most of the puparia were empty; and on agitating the wheat, swarms of flies rose from off the grain, where they had been resting. I was for- tunate in obtaining one of these while in the act of depositing her egg on the grain. Thus interrupted, she placed six on my finger. Three of these I have glued to the paper near her. When depo- sited they were of a pale straw colour, and inconspicuous to the naked eye, unless collected in numbers. On the same day, I found August, 1841. J G7 larvae in the straw, generally above the last joint. They were feeding in or near the joint, with their heads always downwards. The wheat, which had to this time (June 20th) promised an abundant harvest, began to shrivel ; and a practised eye could detect, from the appearance of the grain, in which stalk we were to look for the larvae. From June 20th to July 10th, the flies continued to deposit their eggs on the grain ; though on the last mentioned date but few were DO O ' O to be met with. By July 12th, the grain in this neighbourhood was all reaped ; and on that day I had a sheaf of wheat placed in the library, where I could with more accuracy watch the progress of the larvae remaining in the straw. They continued to feed for some days; when they became quiescent, fixed, themselves by their mandibles in the joint of the straw, and with their heads downwards, gradually assumed a chesnut brown colour ; the outer skin becoming the puparium. From a handful of infested straws placed under a bell glass, I have the following results. Most have perished ; some have passed into the pupa state in the centre of the culm ; a few of the perfect insects I have liberated from the centre of the straw, by opening a passage for them with my penknife ; and great numbers have been destroyed by the Geraphion destructor ; two of which I send with the Cecidomyia. From the sheaf of wheat I have the following results. Many of the larvae perished ; some became pupa? without change of situa- tion ; and the flies continued to rise from the straw until the 31st of July. Of these I succeeded in catching twenty-six. Five are Cecidomyias, and the remainder are Geraphion destructor; some of which are destitute of wings. A small number of pupae are still to be found in the field in the stubble. From this series of facts it might be presumed that the history of this interesting and destructive insect was decided; but the state- ments of observers whose information and accuracy cannot be ques- tioned, prove discrepancies in its history that can only be reconciled by supposing that there are two species under observation. The species now presented will agree with Mr. Say's statement, that 68 [August, 1841. " the perfect fly appears early in June, lives but a short time, deposits its eggs and dies." The remainder of Mr. Say's history must apply to that species which has been so frequently observed to deposit its eggs on the leaf." A letter was read by the Corresponding Secretary from Major James D. Graham, U. S. A., dated July 30, 1841, ten- dering his acknowledgments for his election as a correspond- ing member of the Academy. STATED MEETING, August 17,lS41. Vice President Morton in the Chair.

Written Communication. — A lettter was read from Owen Mason, Esq., of Providence, Rhode Island, acknowledging his election as corresponding member of the Society. Dr. Morton (Dr. Coates taking the chair) made some re- marks on the sutures of the cranium as connected with the growth of the corresponding bones. Headverted to the opinion long in vogue, that the chief use of the sutures was to facilitate the process of parturition ; a theory which is refuted by the fact that they exist in the skulls of all the ovipar- August, 1S41.] 60 ous animals as strongly marked as in those of the viviparous class. That they give a certain increased facility to parturition is unquestionably true ; but their more uniform function is to sub- serve the growth of bones, which they do by osseous deposition at their margins ; hence a suture in the cranium is equivalent to the surface which intervenes between the shaft and epiphysis of a long bone. The latter grows in length by deposition at its ex- tremities, and the epiphysis disappears, like the suture of the cranium, when the growth of the bone is completed. Dr. Morton illustrated these views by means of the skull of a mulatto boy who died when about eighteen years of age. In this instance the sagittal suture is entirely wanting; in consequence of which the lateral growth of the cranium has ceased in early in- fancy, (no doubt when the suture became consolidated,) so that the diameter between the parietal protuberances is less than 4.5 inches, instead of 5, which is about the negro average. The squamous sutures, however, are fully open, whence the skull has continued to expand in the upward direction until it has reached the full vertical diameter of the negro, viz., 5.5 inches. The co- ronal suture is also wanting, excepting some traces at its lower or lateral extremities. The result of this deficiency is seen in the very inadequate developement of the forehead, which is low and narrow, but elongated below by means of the various craniofacial sutures. The lambdoidal suture is complete, thus permitting of posterior elongation ; and the growth in this direction, together with the great vertical diameter already mentioned, has allowed the brain to attain the bulk of seventy-seven cubic inches, or six or eight inches short of the negro average- The growth of the brain and that of the skull are of course con- sentaneous; nor is it probable, that either could be developed without the sutures : hence there is reason to believe that the absence of these may be a cause of idiocy, by preventing the growth of the brain, and thus impairing or destroying its functions. Dr. Coates inclined to the opinion that, in cases similar to those presented by Dr. Morton, the disappearance of the sutures was rather to be regarded as a consequence than a cause ; and took place, as in old age, because the necessity for further extension of 10 70 [August, 1841. growth no longer existed, from the final cessation of enlargement in the brain. Uniting with Dr. Morton in the belief that the office of the sutures was to permit a more rapid development and growth of the cranium, by allowing ossification to go on from several centres at the same time, the bones of the skull, in this respect, resembling the trunk and epiphyses of a long bone, Dr. Coates inclined, at the same time, to the double belief that growth and other changes took place, not at the sutures only, but through- out the whole extent of a living cranial bone. The parietal bone of a newly born infant was not mathematically of the same shape with the central portion of that of an adult. Were the brain, in one of the cases referred to by Dr. Morton, to acquire, by any means, a further enlargement, it ought to be presumed, in the present state of our physiological knowledge, that the bone would enlarge to a corresponding extent ; and it would be therefore, in- ferred that the ossification of the sutures would not limit the growth of the brain. This view Dr. Coates endeavoured to illustrate by a comparison with the opinion of Mr. Serres, that the relative and successive growth of the parts of the brain were a consequence of the relative size of their arteries during the period of formation ; in regard to which, he believed, physiologists were much agreed in the con- clusion that the developement of a portion of the brain and of its corresponding artery were coetaneous processes ; but that if any priority in causation were to be allowed, it should be assigned to the organ ; in consequence of the existence and comparative size in outline of which, it became necessary, if the ability of the sys- tem permitted, that a proportionate supply of blood should be furnished to the part, through a vessel of a suitable size, in order to aflbrd new materials for enlargement. Primary growth, he imagined, took place in the interstitial substance, and that the larger arterial branches, and even the capillaries were rather an instrument or adjuvant than a cause. The formation of additions to existing solids would thus resemble that of the primordiaof the foetus, near which no vessels of the parent are observed, while the vascular appearances are found to approach the newly organized individual at a period subsequent to its formation. August, 1S41.] 71 Dr. Coates called the attention of the Academy to the white- ness, thinness, and semi-transparency of the specimen exhibited by Dr. Morton, in all the lines usually exhibiting the sutures. This he considered, not only as indicating the previous existence of real sutures, but as corresponding with the views entertained, by some late comparative anatomists, in regard to the analogy of parts. He alluded to those who believe the analogous parts in animal formations to exist to a very great extent indeed, although composed of very diversified materials, and adapted to very dif- ferent purposes in the various beings in which they exist.

Professor Johnson exhibited several specimens of crystalloid anthracite and bituminous coal, and stated some of the circum- stances which seem to determine the assumption by this mineral, of certain figures, contrary to the assertion of many mineralogists that it has no definite form. The forms which anthracite occasionally presents are, 1. Ovoid, which causes it, in breaking, especially when the fracture takes place from long exposure to the atmosphere, to fall into spheroidal masses with salient portions strongly reminding us of truncated angles in ordinary crystals. This figure has often been observed in one of the beds of anthracite found on Beaver creek; and a large specimen furnished by Mr. Jacob Thomas of Beaver Meadow, was exhibited, showing the truncated borders along the lines of separa- tion in a very remarkable manner, and also displaying beautiful iridescent colours. It was remarked that coal affecting this form, is frequently found to leave a considerable portion of oxide of iron among its earthy residue; but that the whole of the latter was not usually a large per centage of the coal. 2. The next definite form mentioned as affected by coal, is a radiated structure well characterized in several specimens from the third bed, from the bottom of the formation at Bear-gap, Dauphin county, Penna. This structure was likewise illustrated in a sample of Welsh bituminous coal. The radiations generally proceed from two points at no great distance from each other and forming two sections of conical surface, unite at certain distances from their points of departure into a single cylindrical section near the termi- nation of the rays. The exterior of these radii is of a silky lustre, striated, and sometimes interrupted by the interposition of frag- ments of organic remains, in the state of fossil charcoal. Very large stems are occasionally found with radiated, crystalloid an- thracite adhering to the opposite sides, the directions of the striae being on the two sides very nearly the same. 3. The rhombic hexaedron was exhibited in a well marked specimen of anthracite adhering to its accompanying slate. Few mineral forms are better defined than this mass of anthracite. The angles can be determined with the goniometer with tolerable pre- cision, liable however to the slight uncertainty arising from the presence of organic bodies, tending to oppose the crystalline ar- rangement. 74 [August, 1S41. 4. An octahedron with tolerably well-defined faces striated in different directions on the adjoining sides, was exhibited, and the circumstance of possessing- a large portion of earthy matter was noticed, as belonging to many samples of coal which exhibit this exterior aspect. The presence of several well marked crystalloid forms being thus established, Prof. Johnson adverted to the argument which such forms had been supposed to furnish against the vegetable origin of coal, and stated that in the very samples under examina- tion were seen the most incontrovertible evidences of the source from which not only bituminous coal, but anthracite also had been derived. In one and the same specimen of the latter, were seen mineral charcoal, natural coke, and true anthracite, indicating as well the vegetable origin of all, as the process of formation, by which the last two had probably been derived from the interme- diate state of bituminous coal. In accounting for the supposed impossibility of crystalline struc- tures being formed out of organic matter, he observed that a dis- tinction is to be drawn between organic elements and organized substances, and that the former may often be so proportioned, when derived by distillation, fermentation or other chemical re- action from the latter, as to be capable of assuming definite figures. The production of coal from vegetable bodies is supposed, on all hands, to have resulted from a slow chemical decomposition of the latter and the establishment of new orders of affinity between the original constituent atoms. The carbon as well as the other materials of vegetables was by this process reduced, at least in part, to the condition of ultimate molecules, instead of being merely mechanically divided into small particles. It would there- fore be capable of obeying any law of movement which either its own affinities or those of the earthy constituents which had en- tered into the composition of the vegetables fiom which it had been derived, might tend to impress. That it is the earthy con- stituents which determine the forms assumed by coal, seems pro- bable from the fact that the more earthy residuum of a particular kind any coal contains, the more prone does it appear to be to assume a crystalloid structure. Reference was made, in this connexion, to those cubic, rhombic and columnar structures which ofien occur in both anthracite and bituminous coal, and which not unfrequently exhibit to the eye, especially after partial incineration, the clearest evidence of a ten- dency among the earthy ingredients to regulate the arrangement of forms throughout the whole mass. Prof. Johnson also stated that the result of a considerable number of analyses of the ashes of coal, appeared to favour the presumption that the two principal con- stituents, silica and alumina, are in definite proportion to each other, August, 1841.] • 75 and may therefore have a power of assuming definite forms. The oxide of iron in the ashes is commonly derived from the decompo- sition of pyrites, while the lime and magnesia in the coal are pro- bably in the state of carbonates, unless where the production of sulphuric acid by the decomposition of the pyrites has converted the former into gypsum and the latter into epsom salt. From this latter play of affinities the carbonate of iron would be produ- ced, and subsequently the sesquioxide, often seen covering the in- terstices of outcrop coal and forming bog ore in the springs which proceed from coal seams, the coal in the meantime retaining the form impressed by the agency of the silicate of alumina, and hav- ing a portion of its interstices or those of the underlying slates filled up with crystallized sulphate of lime. Admitting the justness of this view of the causes which produ- ced crystalloid forms in coal, we have no more difficulty in ac- counting for the number of different forms which it occasionally exhibits than for the analogous variety in regard to other minerals ; the carbonate of lime, for example, which, as is well known to mineralogists, takes on a far greater number of distinct forms. Prof. Bailey stated, that he had recently examined specimens of Calcareous marl from the cretaceous formation discovered by J. N. Nicollet, Esq., on the Upper Missouri, above the mouth of the Sioux river. These specimens proved to contain fossil Fora- minifera, (Polythalamia of Ehrenberg,) similar to those previ- ously detected by Prof. Bailey in the calcareous portions of the same formation in New Jersey and Alabama. He also mentioned certain silicified wood found near Fredericks- burg, Va., in the feldsphalhic sandstone, called by Prof. W. B. Rogers " upper secondary sandstone." This wood is in a pecu- liar state of preservation, the vegetable matter having been com- pletely replaced by silica, without any filling up of the cells or tubes. In consequence of this state of the wood, it is easy to subject it to microscopic examination without the trouble and ex- pense of forming polished slices. All that is required is to break off thin pieces with the point of a knife and moisten them ; they then show the most delicate markings of the tissue beautifully preserved. The discs with concentric rings, and other characters peculiar to Conifera, are so distinctly visible as to leave no doubt, that this wood which is commonly called in Fredericksburg, " Petrified hickory," is really fossil pine. In the same formation, fossil plants of the family Cycadeas, have been detected. 76 [August, IS41. MEETING FOR BUSINESS, August 31, 1841. Vice President Morton in the Chair.

Amnicola attenuata. — Shell very long and slender, with six obliquely revolving, very convex turns, separated by a deep suture ; aperture small, ovate, with the peritreme level and continuous, as in Cyclostoma. Length A inch. Hab. a spring in Montgomery Co. Virginia, connected with Roanoke river. Obs. — Very like, but more slender than Cyclostoma lapidaria, Say ; which I refer to this genus, as well as C. Cincinnatiensis, Lea ; retaining for this species Mr. Anthony's specific name Sayana, under which appellation the shells were distributed by this gentleman. This substitution is necessary, because the pre- viously described Paludina Cincinnatiensis, is an amnicola. Mela- nia integra, Say, is an amnicola also.

September, 1841.] 79 Obs. — This species is a valuable acquisition to Malacology, as it enables us to place the genus Ancylus among the Limneans, where it has hitherto held but a doubtful place. Any one who has exa- mined the animal of Ancylus, cannot have failed to observe its similarity to Planorbis ; and some authors assert that it ascends to the surface of the water to breathe air. This I doubted, because the species with which I am familiar, inhabit the interior of bivalve shells, or the surface of stones in rapid water ; whence it is impos- sible for them to rise to the surface, and regain their previous position. I hence infer that they breathe water, as well as the Physa above described, inhabiting as it does, the middle of a river, in rapids nearly two feet deep at low water, and without objects rising above the surface. It is highly probable that air-breathing Ancyli exist; and it is even possible that the same organ may be adapted to the respiration of both air and water.

Ferdinando Tartini, Secretary of the Italian Scientific Convention, an- nouncing the third Annual Reunion to take place at Florence in September of the present year. A paper was read from Dr. Edmund Ravenel, of Charleston, South Carolina, in reference to some organic remains of Crus- tacea, &c. discovered by him in the fossiliferous beds to the west of that city, viz. : September, 1841.] 81 "Description of two new species of Fossil Scutella, from South Carolina, by Edmund Ravenel, M. D. " Scutella Caroliniana. — Specific character : nearly round ; slight- ly convex above ; posterior margin truncated ; ambulacra short, ellip- tical, the two posterior slightly curved and nearly a third longer than the others ; in a line with each there is an oblong perforation extending almost to the margin ; between the two posterior ambu- lacra, there is another perforation, longer than the others, and more central, at the extremity of which, beneath, near the mouth, is the vent. Mouth central ; diameter about six inches. Scutella macrophora. — Specific character : sub-ovate thick ; margin thick, truncated posteriorily ,° notched slightly opposite the anterior ambulacrum ; more deeply, opposite the lateral, and still more so opposite to the posterior ambulacra. Ambulacra elliptical ; the posterior pair long, and gracefully curved, so as to give room between them, for a very large irregular perforation, the margin of which is considerably raised, extending to the centre of the shell, giving the upper surface a remarkable elevation. The under surface is flat, rather hollow, particularly near the opening ; mouth anterior to the centre ; anus distant from the mouth one-fourth of the space from the mouth to the posterior margin. Diameter of large specimens nearly four inches. These fine fossils are found in a calcareous deposite upon my plantation on Cooper River, in St. Thomas's Parish, about 17 miles from Charleston. The limestone is granular, and remarkably adapted to the pur- poses of calcareous manure. In digging it out and spreading it on the fields, these fossils are found in considerable numbers ; the S. macrophora is particularly abundant and perfect. The S. Caroliniana is also abundant, but from its size, and the number of openings in it, it is very easily broken, and is only obtained in fragments. I have only one perfect specimen and that is not quite 2} inches in diameter. In examining these fossils in the light, the surface exhibits bright chrystalline faces ; the material of the shell seems to have become crystallized, since the destruction of the animal matter. 82 [Setpember, 1841. It is perhaps remarkable that many of the crustaceous remains in this deposit are well preserved, while the shells proper are for the most part decomposed. A few specimens of two or three spe- cies of Pecten, of one or two Ostrese, a Plicatula and a Balanus, are occasionally met with, while imperfect casts of numerous spe- cies are very common." The calcareous deposit to which the preceding fossils belong, is the newest cretaceous formation of Dr. Morton, who first described its relative position and organic remains in his Synopsis, published in 1834. Dr. M. supposed these beds to be of the same age of the white chalk of Europe ; they are based on the ferruginous sand strata in New Jersey, North and South Carolina, Alabama, &c. ; and the two deposits contain a few fossils which are specifically the same. In fact, the Eocene or lower tertiary, also embraces some species of shells identical with those of the newer cretaceous ; whence the latter beds, like those of the celebrated plateau of Maes- tricht, may prove, as Dr. Mantell has suggested, to be a link between the chalk and the tertiary beds, without being contem- poraneous with either. Mr. Quinby made some remarks on the mineral resources and physical geography of that portion of Peru which em- braces the eastern ridges of the Andes. He alluded to the treasures which were secreted by the Peru- vians at the epoch of the Spanish invasion, and which have never yet been found, notwithstanding the continued search of the inhabi- tants. But the river Chucabamba possesses natural treasures of great value, for its sands are auriferous for several leagues above and below the temple of the sun. The inhabitants procure it by cutting the wool on sheep skins to half an inch in length, and then sinking them in the rapids, and at the base of the falls of the river, in which position the skins with the woolly side up, are suffered to remain from six to twenty-four hours. They are then carefully removed from the water, and turned wool side down into a batea or tub of water ; the gold is thus washed out, and is collected without fur- ther trouble. September, 1841.] 83 Mr. Quinby adverted to the celebrated ruins of the Temple of the Sun at Huanuco viejo, (Tiaguanico*) the Cyclopean fortress, — tbe walls composed of enormous masses of square and oblong stones of marble, greenstone and greenstone-porphyry, — all which, with their bas reliefs and other ornaments, remain in a remarkable state of preservation. These ruins, as is well known, date beyond the dynasty of the Incas, to a people, however, of the same race, and probably of nearly similar political and religious institutions. Mr. Quinby crossed and recrossed the Andes twenty-four times, at seven or eight different passes ; twice from Naranjal, (on the gulf of Guayaquil, one degree and a half south of the equator,) to the city of Cuanca, the capital of the province of Assuay, a little south of Chimborazo ; and having spent more than two weeks at the foot of the Peak of Raura, at least a thousand feet above the line of perpetual snow, he pronounces it the most sublime spot he has visited on the Andean range. Besides the Peak of Raura, which he believes to be at least as high as Chimborazo, there are innumerable smaller ones rising on the range of the Cordilleras, to the north and south, having their bases resting on perpetual snow, and throwing up their snow-clad apices into the pure and attenuated atmosphere, almost beyond the reach of the Condor itself. The largest and nearest of these peaks is that of Nueva Potosi, the base of which approaches within one league of that of Raura ; and the intervening space is occupied by the lake called also Neuva Potosi, the surface of which is about 500 feet above the lower limit of perpetual snow ; and as this line, within the tropics is not less than 15,500 feet above the level of the ocean, the lake must consequently have an elevation of 16,000 feet. The water of this lake makes its escape by a subterranean passage on the western slope of the Andes, and also gives rise to the river Haura, which reaches the Pacific at Huacho, the celebrated salinas of the south- ern hemisphere. Mr. Quinby also described the Lake of Raura, one league north of that of Potosi, and giving rise to one of the principal branches of the Amazon. Both of these lakes are the *See page 36 of these Proceedings. 84 [September, 1841. frequent receptacles of avalanches of ice and snow from the super- jacent mountains, presenting the rumbling sound and tremulous sensation of an earthquake, and forcing vast bodies of water over the precipice to make their way by the courses of the Amazon to the Atlantic ocean, a distance of five thousand miles.

Poulson, Jr., Charles N. Bancker, Robert Bridges, James C. Booth, Paul B. Goddard, Joseph Carson, Thomas D. Mutter. September, 1841.] 85 Mr. J. S. Phillips read the following paper on the Nomen- clature of Natural Science. The confusion in the nomenclature of Natural Science, owing to the number of synonymes with which it is burthened, makes it desirable that some fixed rule should prevail, by which naturalists mio-ht determine to whom to credit species, and what names shall have priority. With a view to call the attention of the Academy of Natural Sciences to the subject, I have thrown together some of the opinions and arguments urged by different parties, in the hope that eventually some definite rule in nomenclature may be generally adopted. In determining the right to names of species, the only two points worth noticing, are, which description was first read before a society ; or, which was first printed and published. Now, the arguments that occur to me in favour of priority of reading, are, that when the author has read his paper, and handed it over to the society before which he read it, he has done all in his power ; that it is then taken out of his hands, and he has no control over the time when it is to be published ; and, that, because his society, for whatever cause, delays the publication until another naturalist has published it, it would be unfair that the former should be deprived of the credit of his investigations, by circum- stances over which he has no control, and that too, after having done all that was in his power. Another reason urged in favour of the first read description is, that in referring to old descriptions, the date when the paper was read is precise — the day when read being always one of the meet- ings of the society, and printed in the journal or transactions with the date, and therefore absolutely determined ; but the actual day of publication not always so readily ascertained. In answer to the first, it may be urged, that if merely reading a paper secures the species, it will produce indifference as to whether it is ever published or not ; and naturalists in general will be at a loss *o know what has been done in the case ; while specimens will remain unlabelled and unknown, because no one is particularly interested in publication ; but if priority of publication be the stand- 12 86 [September, 1841. ard, other naturalists would not be long at a loss to know what has been done ; and as the rest of the community interested are a vast majority, their convenience should have great weight in the matter. And when the meetings are not open to the public, the reading is still less a point to be depended upon, as the committee to whom the paper is referred might retain it for months, and in some cases years, and in the mean time numerous species be added to the paper through the carelessness or connivance of the committee, a long time after it was read, and perhaps after another naturalist had published them ; and thus if the first read be the rule, a great opportunity for trick and injustice be offered to the unscrupulous. And even when the meetings are public, the author might borrow the paper under pretext of verbal alteration or other excuse, and then interpolate additional species. The same objections in part hold good against the other argument in favour of the first read description : the correctness of the date of publication may be ascertained by all, but it is not so certain that the description of a species was read on a particular evening. The arguments in favour of priority of publication are, among others, that it would be extremely unfair, that a man who has spent months or years in searching for species abroad, and then perhaps been at the expense of publishing them himself, should be deprived of his hard-earned credit, by some one who has merely read a paper of which the other could have no knowledge ; while, if he had known that the Fauna or Flora of that district had been collected and des- cribed, he would have made his researches in another quarter. Another reason is, that by making mere reading the standard, all who were not present at the time, or had access to the minutes of the society, might remain for a long time in ignorance ; especially as a paper might not be recorded until reported on by the commit- tee, who might retain it for years when the volumes appeared at long intervals : even the members of the society who were absent when the paper was read, would remain at a loss to know whether any particular species were described or not. In this way the numerous specimens which are constantly scattered through va- rious collections would remain a long time undescribed and September, 1841. J 87 unknown ; as the possessors would be always in doubt, whether some one else had not previously described them without publish- ing: and thus the keeping up with the state of any department of natural history would be impossible, as no one could know what was doing in more than one or two societies. In the case of societies holding their meetings with closed doors, the reasoning applies with still greater force, as none but the members of that society could have the chance of any knowledge of the matter. There is also another reason for preferring priority of publica- tion ; that many naturalists are working away quietly, exploring sections of country around their places of residence, in remote and unfrequented parts, who have no access to public institutions, and whose only means of knowing what is done must be through the press. The great number of synonymes with which natural science is burthened, is in great part owing to the want of a fixed rule in this matter ; and it would seem that priority of publication would lessen the evil, more than the rule of having been first read ; as several des- scriptions might be read within a short time of each other, in different places, by parties in ignorance of what is doing elsewhere ; and then their various names be introduced into the nomenclature ; but when once published, it is every one's business to know what has been described, as the opportunity is offered to every one to ascertain ; and if a description be made in voluntary ignorance, it then could not stand. And not among the least of the arguments in favour of priority of publication, is, that of the two parties in the case, the describer, and the public of naturalists who are to read the description, the latter, being an immense majority, would find priority of publication contribute greatly to the interest of science generally, in promoting early publication, and preventing confusion by synonymy ; and to individual convenience, in enabling those who choose, to keep close up with the state of any branch of natural history. Now, as the descriptions would not be written, if there were to be no readers, the latter being so important a party in the matter, may take upon themselves to decide what rule shall obtain in the premises. 88 [Setpember, 1841. While on the subject of the nomenclature of natural history, there is an evil which is growing so rapidly as to deserve notice; That is, the custom when genera are sub-divided, or species transposed from one genus to another, to credit the old species to the naturalist who constitutes the new, or even modifies the name of an old genus ; thus depriving the original describer of his species, because it is associated with another series of species, or because the termination of its latin name be altered to suit the altered gender of the genus. In this way Linneus has been robbed of a large portion of his labours ; not by Lamarck, for he appears to have been superior to such littleness ; but by later naturalists, who have credited the old species of Linnaeus, to Lamarck as an authority and precedent for their own innovations and appropriations. When fairly viewed, it can hardly fail to strike every disinterested mind, that the credit of the original description of a species should remain with the describer; he described the characters of a group, a spe- cies, and whether that species belongs to one or another genus, his description of its character must remain : indeed there is no show of any attempt to change such description ; and if in the progress of science, new divisions of genera, or translations of species from one genus to another be found necessary ; then credit the generic change to the constitutor of the genus, and the species to its original describer, thus Planorbis Corneus. Lin. Lam. This, besides being strictly just to all parties, would have the effect of preventing useless and absurd modifications, by removing one of the chief incentives — the having the name of the innovator tacked to specific names. MEETING FOR BUSINESS, September 28, 1841. Dr. Goddard, in the Chair. The corresponding Secretary's report was read and adopted. The committee on Mr. Haldeman's paper, " Description of September, 1841.] 89 two new Freshwater Shells," reported in favour of publica- tion. The committee on Dr. Ravenel's " Description of two new fossil species of ScutellaV' reported in favour of publication. The committee on Mr. Speakman's memoir on Light and Heat, reported in favour of depositing it in the library of the Academy. The committee on Mr. Phillips's communication, read at the last meeting, on the claim to priority in the description of new species, submitted a report, which was ordered to be printed with the proceedings of this meeting. The committee to whom was referred the consideration of the views and suggestions of Mr. Phillips concerning the rights of authors; and of the practice of changing original names to suit new made nomenclatures, havingcarefully examined these interesting and important matters, respectfully recommend the publication of Mr. Phillips's communication in the bulletin of the proceedings of the Academy ; and further, beg leave to submit to the Academy a few brief remarks : — In the opinion of your committee, the establishment of well- defined, and readily understood principles, as bases of nomencla- tures, especially as regards the priority of the rights of authors in the history of nature, is most essential ; not only because it will have a direct tendency to stimulate labourers in science to profound investigation and research, and secure to them the harvest they may achieve, and thence facilitate the acquisition of precise know- ledge to all ; but it will likewise be eminently conservative of the integrity and reputation of science itself amongst us. It appears to your committee to have been conclusively under- stood by many naturalists, from precedents established in scientific institutions both in Europe and in this country — by usage, if not by written law ; that the date of a printed publication, accessible to all, to men of science as well as to others, announcing new discoveries, shall fix and determine the right of priority; and hence names and 13 90 [September, 1841. descriptions thus put forth, are entitled to and should receive the sanction, and be adopted, throughout the scientific world. In contradistinction to this, your committee are aware that there exists an opinion, that an author might claim precedence, from the time his discoveries were read before a scientific society, and with- out reference at all to the time of printing or general circulation. But this seems to your committee, a very uncertain and vague expe- dient, the source of perpetual embarrassment and confusion; and much of the retardation of the spread of knowledge maybe attributed to this cause. Many societies issue their transactions through the press at long intervals, months, even years, elapse before their discoveries reach the public : thus, it seems to your committee, manifestly unjust, that other collaborators should await such tardy enunciations of scientific knowledge, and so hazard the loss of their labour, and that too, by acts, even farther removed from their control, than are the periods, or the means of publication of the transactions of such societies, from the influence of their own members. Your committee deem it inexpedient at this time to extend their observations ; enough, in their opinion, having been adduced to warrant their conclusion — that the most obvious and rational cri- terion by which to test the merits of conflicting claims to originality, is solely, the printed and published testimony. In relation to that portion of Mr. Phillips's communication, which alludes to the modifications and changes in the designation of genera and species made in new nomenclatures, without assigning credit, where it is justly merited, — thus wresting from the natu- ralist the honour acquired by his oftentimes onerous and unrequited toil, — your committee trust, that the Academy of Natural Sciences of Philadelphia, will sustain them in an expression of decided dis- approbation of a practice, so fraught with evil, doing injury alike to science, and to its collaborators.

This species differs from Say's Bat, not only in colour, but in its much shorter ears and tragus. The size and shape of the tragus, we have found an infallible guide in our American Bats; the ears of the present species, when alive, are always erect, whilst those of Say's Bat are folded backwards like those of the long eared Bats — Plecotus.

The tail is enclosed in the interfemoral membrane, except the penultimate joint, which is free. The anterior upper fore teeth, instead of being sub-simple, as in the (V.

Remarks. — Say's Bat (Ves. subulatus) has been several times described. It was first observed by Say, at the head waters of the Arkansas, within sight of the Rocky Mountains. It was subsequently described by Richard- son, who obtained it at the Saskatchewan It was given by Le Conte, in McMurtrie's translation of Cuvier, under the name of Ves. Lucifugus. Pro- fessor Green, in Doughty's Cabinet of Natural History, (vol. 2, fig. 270,) gave a correct description of it under the name of Ves. domesticus. He, however, erred in arranging it in the preface of his descriptions, under Rafinesque's genus Nycticejus, to which it does not belong. The last notice of it is found in Cooper's Monograph of Vespertilio, in the New York Lyceum of Natural History. This species has a very extensive range. We obtained it in the widely separated localities of Carolina and Labrador, during sum- mer. The Ves. Carolinensis is found in autumn, winter and spring, in Carolina; but appears to migrate northwardly in summer, and is at that season common in the State of New York. The Ves. monticola and Ves. Virginianus have not been met in Carolina or Georgia, and appear to be Northern or Alpine species, and no doubt exist in the Northern States. The Ves. Carolinensis may be easily distinguished from the other closely-allied species, by the large size of the first upper incisor; the second which suc- ceeds it being so minute as to require the aid of a good magnifier to detect it. The genera of Bats have within the last few years been greatly multiplied, in order to include the vast number of new species which have been accu- 94 [October, 1841. ruulating in European museums. The last revision we have seen was by Gray, of the British Museum, who has divided the bats into forty-eight genera. The two species here described, belong to the genus Vespertilio, as now restricted. It is characterised by having four incisors in the upper jaw, in pairs on each side, near the canines, with a large, unoccupied space between them. The only species as yet described in the United States, that can be referred to this genus, are Ves. Carolinensis, Ves. noctivagans, Ves. subulatus, Ves. monticola and Ves. Virginianus. The existence of a Brown Weasel in America, which does not become white in winter, has been doubted by some naturalists; and by others, the species has been regarded as the Mustela vulgaris of Europe. Dr. Harlan, (Fauna Americana, p. 61,) under the name of Mustela vulgaris, does not appear to have described an American species. His description appears in- tended for the common Weasel of Europe, which we think does not exist in America. Dr. Godman, after giving figures of the Ermine, both in winter and summer colours, considered the latter as the species improperly referred to Mustela vulgaris of Europe ; and in accordance with the views of Charles L. Buonaparte, the Ermine was regarded as the only species of American Weasel. Dr. Richardson, (Fauna B>reali Americana,) under the name of Mustela (Putorius) vulgaris, has described from specimens obtained by Captain Bayfield on the borders of Lake Superior, and also from others procured by himself at Carleton House, which he regarded as agreeing in all respects with the European species. He concludes, by stating, that this species, like the Ermine, "becomes white in winter." We had an oppor- tunity, in the Museum of the Zoological Society of London, of examining the specimens referred to by Dr. Richardson, and of comparing them with Mus- tela vulgaris, and were satisfied that the species were distinct; yet, unless he was in error in stating that the American species became whire in winter, we are not certain that the species we are about to describe is identical with the specimens he referred to. Mustela fusca. — American Brown Weasel. M. (fusca). Corpore inter Mustelam erminiam et Mustelam vulgarem in- termedio ; cauda illius breviore, sed hujus longiore; apice nigro; vellere supra fusco ; subtus albo. American Brown Weasel. — Intermediate in size between Mustela erminia and Mustela vulgaris ; tail shorter than the former, but longer than the latter, with the extremity black ; brown above, white beneath. The body is long and slender, but far more robust than that of Mustela vulgaris ; the feet especially appear one-third larger, and mure thickly clothed with fur, which completely covers the nails. The ear is a little longer, and more pointed, than that of either the Ermine or common Weasel. The white on the lower surface is not mixed with brown hairs, a3 in the Mustela vulgaris, and not only occupies a broader space on the belly, but extends along the inner surface of the thighs as low as the tarsus, whilst in the Mustela vulgaris, the white scarcely reaches the thighs. Colour. — The whole of the upper surface, to within three-fourths of an inch of the tail, is of an uniform dark fawn colour. On the upper surface of the tail, the hair is darker brown than the back, and its extremity is for an inch nearly as black as that of the Ermine. In writing this description, we have several specimens of the European Mustela vulgaris before us; and the ends of the tails in that species are uniformly brown, with here and there a black hair interspersed. Although the hair of the present species, at the extremity of the tail, is black, like that of the Ermine, yet these hairs are short and soft, and more like fur, and do not present the long and coarse appearance of that of the former species. The whole of the under surface is pure white; this colour does not commence on the upper lip, as in the Ermine, but on the chin, extending around the ^Tes of the mouth, and by a well-defined line, along the neck, inner Mustela erminia.

The white on the lower surface is not mixed with brown hairs, as in the Mustela vulgaris, but extends lower down on the legs. Of the colour of this species, in winter, we cannot speak with positive certain- ty, but feel pretty confident that it is the same as in summer, and that it does not (at least in the latitude of New York) become white in winter. We, many years ago, kept several young Ermines in confinement, as well as one of this species. The Ermines all became white in winter, although some of them were not fully grown ; the present species underwent no change in colour, but remained brown during the whole winter. On another occa- sion, a specimen of a brown Weasel was brought to us in the month of December, which had been caught in a trap. At that season, the Ermines are uniformly white. A Weasel exists in the Southern States, and is found as far south as the upper parts of South Carolina and Georgia. It has always been represented to us as never becoming white in winter ; and although we possess no specimens at present, we are inclined to regard it as this species. Dimensions of specimens before us, of the three species referred to above: Length of head and body, Tail vertebra?, Including fur, Height of ear, posteriorly, 0 The specimen of the American Brown Weasel, described above, was ob- tained at Long Island, in the month of May. We subjoin a description of another species of Mustela, which, although recently made known to naturalists by Dr. Lichtenstein, of Berlin, who re- ceived his specimens from the vicinity of the city of Mexico, was not hitherto known to exist as far north as the locality from which we ob- tained it. We agree with Swainson, Lichtenstein, Dr. Richardson, and the most eminent European naturalists, that America divides itself into three natural zoological boundaries : the first including our whole coun- try from the farthest north, to the tropic of Cancer, where the tropical forms commence, to be called North America ; the second, including the Tropics, called Central or Tropical America; the third, South America, including all that region lying south of 33 J south latitude. The southern points of Florida and California will, in this case, be the southern bound- ary of our North American Fauna. Our specimen was received from North California about latitude 40°.

Glossy Arvicola. — Body long and slender, nose sharp, ears and legs long, fur smooth and lustrous ; dark brown above, hoary brown beneath. Form. — This species presents more distinctive markings than any of our American Arvicola ; its body is less cylindrical, and its nose less obtuse than any of our other species; its ears are prominent, rising two lines above its smooth, compact fur; its lower incisors are very long, and much exposed and considerably curved; tail longer than the head, thinly cov- ered with short hairs ; legs long and slender, giving the whole animal that appearance of lightness and agility observable in the Mouse. Colour. — Incisors, yellowish-white. The hairs, which are very short, like those on the Pine Mouse of Le Conte, are at the roots on the upper surface, plumbeous, broadly tipped with brown, giving it a bright chest- nut-brown colour ; the hairs, on the legs and toes, are a little lighter ; on the under surface, the colour is cinereous.

Sharp-nosed Arvicola. — Larger than Arvicola Pennsylvanica ; tail shorter than the head; legs small, slender; heel very short ; the body, above, dark, rusty brown ; a soiled yellowish grey beneath. The head of this species is rather long, and the nose sharper than the Arvicola in general. The lower incisors are long, and very much curved. The body is less cylindrical than Wilson's Meadow-mouse ; the ears are circular, sparingly hairy within and well covered with fur exteriorly; whiskers shorter than the head ; tail thinly clothed with hair. Extremities. — Legs covered with short hairs. The fore feet have naked palms ; claws small. The tarsus is more than a third shorter than that of the much-smaller Arvicola Pennsylvanica ; the fur on the back is also shorter. Colour. — Incisors yellowish-white ; the fur, from the roots to near the tips, is greyish-black; the tips are yellowish-brown and black; giving it a rusty-brown appearance. The legs and tail are light brown ; the chin a soiled white ; the fur on the under surface of the body, is dark-cinereous to the tips, where it is light-coloured.

His descriptions, however, in every department of natural history, are so short, vague and imperfect, that it is impossible to identify his species with any degree of certainty. They have created such confusion in the nomenclature, that nearly all European and American naturalists have ceased to quote him as authority. Dr. Richardson has, moreover, described an Arvicola from the Rocky Mountains, which he has referred to the Noveboracensis of Rafinesque, which differs widely from the above species. Habitat. The specimen which we have described was obtained by Dr. Brewer, near Boston. We received another from Mr. John W. Audubon, who procured it at the Falls of Niagara. We have also frequently found it in the northern parts of New York, where the Arvicola Pennsylvanica also exists. It appears, however, not to be found as far to the south as the latter species, as we have sought for it in vain in Pennsylvania. Arvicola scalopsoides. Mole Arvicola. A. (Scalopsoides.) Capite crasso ; naso obtuso ; vellere curio, molli, bombycino instar velleri Talpre ; supra albo-fusco ; subtus plumbeous. Head large, nose blunt, fur short, soft, silky and lustrous, like that of the Mole. Colour, above, light brown ; beneath, plumbeous. This species, of which we have obtained many specimens from Long Is- land, and which is not rare in the vicinity of New York, is very distinct from Wilson's Meadow Mouse. His diminutive figure in the 6th vol of his Ornithology, is not very unlike this animal ; but his descriptions, both of form and habits, which apply very correctly to Arvicola Pennsylvanica, have no reference to the present species. The head is thicker and much shorter than that of Wilson's Meadow Mouse; the body cylindrical ; ears scarcely rising above the integument, and completely concealed by the fur. The legs and tail are short ; the lat- ter not as long as the head, and both are covered with very fine and short hairs. The fur on the back, which is soft and fine, and not half the length of Wilson's Meadow Mouse, has none of the coarse hairs which are found in that species. On the under surface, the fur is very short, not more than a line in length. Colour. — The teeth are yellowish white; the fur on the back is, from the roots, dark plumbeous, tipt with light ashy brown. This colour continues uniform till it reaches the sides, where there is a distinct line of demarca- tion, commencing at the chin and running along the neck and sides of the thighs. The whole of this under-surface is of a light cinereous colour, the hair being plumbeous at base, and so lightly tipt with white as to appear in some parts spotted with dark blue and ashy white. This species bears a strong resemblance to the Pine Mouse of Le Conte (Psavnpmys Pinetorum,) which is also an Arvicola, than to any other. It is, however, larger, differs considerably in colour, and is destitute of the chestnut brown on the cheeks, which are the characteristic marks of that species.

Reddish gray above ; cheeks, and line along the side, light ferruginous. Incisors, y Canines, -jg Molars, ^ j 16 Teeth. Form. — Size about a third smaller than the house mouse. Head rather broad ; eyes moderate, placed much forward ; nose much pointed ; ears broad, extending a little beyond the hair, slightly furred without and along the edges on the inner surface; legs short; whiskers reaching to the ears ; tail a little shorter than the body, flattened on the sides, rounded above and beneath, covered with a thin coat of very short hairs. Legs clothed with soft hairs lying close and smooth. The fore feet have naked palms, and four toes with a callous skin, protected by a very minute nail in place of a thumb. The outer toe considerably shorter than the inner, the two middle ones are nearly equal, the claws are slightly hooked ; soles of the hind feet naked. Colour. — Teeth yellow. Fur on the back plumbeous at the roots and tinged with black and reddish gray at the tips ; cheeks, and a line along the sides, light ferruginous. Under parts very light buff. Tail brownish drab above, a little lighter beneath, nails white ; eyes black. This little quadruped, the smallest of the genus at present known in our country, has been obtained in several localities in South Carolina, and ap- pears to be sparingly diffused throughout the whole State, except in the mountainous districts. It is occasionally found in the vicinity of Charles- ton, generally in grassy and shrubby fields, especially in the waste lands covered with the brome grass (Andropogon dipitiflorus, ) of this country, as also in the fields of crab grass, (Digitaria sanguinalis.) I have occa- sionally found its nest among the long grass on the surface of the eartli formed of the withered blades of various species of grasses, sometimes con- taining a small store of the seeds of the several species of Paspalum, Digi- taria and Panicum, especially of the Panicum Italicum. The specimen from which this description was taken, was a little the largest of a great number that I have at different times examined. It was a female, procured on the 10th of December, containing four young in its matrix. I presume, therefore, that they produce their young throughout a great portion of the year, and are very prolific. One which 1 kept in confinement for several months, refused animal food of every kind, and fed only on grains. Dimensions — Length of the head and body, 2 inches, 9 lines.

Mouse with long ears ; tail shorter than the body ; bright orange co- loured above, light buff beneath. Form. — This species bears a general resemblance in form to the white- footed mouse. (Mus leuocpus.) It is, however, a little larger, and its ears rather shorter. Head long, nose sharp, whiskers extending beyond the ears. Fur very soft and lustrous. The legs, feet and heel clothed with short, closely adpressed hairs, which extend beyond the nails. Ears thinly covered with hair, which does not entirely conceal the colour of the skin. Mammae four, situated far back. Colour. — The head, ears, and whole upper surface is of a bright orange colour; the fur being for three-fourths of its length from the roots, dark plumbeous. Whiskers nearly all black, with a few white hairs intersper- sed ; tail above and beneath dark brown. On the under parts, the throat, breast, and inner surface of the forelegs are white ; the belly light buff. There are no very distinct lines of separation between these colours.

It is at the same time a great climber. We have only observed it in a state of nature in three instances, in the oak forests of South Carolina. It ran up the tall trees with great agility, and on one occasion concealed itself in a hole, (which apparently contained its nest,) at least thirty feet from the ground. The specimen we have descri- bed was shot from the extreme branches of an oak in the dusk of the even- ing where it was busily engaged among the acorns. It is a rare species in Carolina, but appears to be more common in Georgia, as we received from Maj. Le Conte, three specimens obtained in the latter State. Note. — We have arranged this species under the sub-genus of Mr. Water- house, proposed in the Zoological Society of London, Feb. 17th, 1837. (See Transactions.) It is thus characterized. "Subgenus Calomys (from K*aoc beautiful, and Mus.) Fur moderate, soft. Tarsus almost entirely clothed beneath with hair. Front molar with three indentations of enamel on the inner side, and two on the outer ; and the last molar with one on each side. The type, Mus (calomys,) bimaculatus.

This species is closely allied to the Arctomys empetra, which exists in the northern part of our continent; but the feet are yellow, instead of black, as in that animal; and the belly is yellow, instead of deep rusty- red; aud the colouring of the hairs on the back consists of yellowish- white and black, instead of rusty brown, black and white.

Woolly Squirrel. Hair long and woolly ; tail, large and bushy, scarcely distichous ; nose, ears and feet, nearly black ; upper surface, grizzled dark grey and brown ; under parts, pale brown. Form. — In size, this species is little less than the Fox squirrel, (Sciurus capitratus.) The ears, in the two specimens which are before us, are de- cumbent at the ends, as if the animal, in a living state, did not carry them erect, as is the case with the squirrels generally; head short, ears large, thickly clothed on both surfaces with short hairs ; feet and toes hairy to the extremity of the nails. Colour. — The incisors are dark orange on the outer surface. The whole head, both on the upper and lower surface extending to the neck — the ears, a spot behind the auricle, fore legs to the shoulders, and hind feet to above the heel, black, with a few greyish-brown hairs intermixed. The long fur on the back is, for half the length, light plumbeous, then a line of light brown, and tipt with white and black. The hairs on the tail, in which the annulations are very obscure, are, for one-third of their length, brownish- black, then light brown, then brownish-black, and tipt with ashy white. On the under surface, the hairs, which are short, are at the base light plumbeous, tipt with light brown and black; the throat is light greyish- brown.

On the upper surface, the head, neck, back and tail are light grey, formed by hairs which are light plum- beous, from the roots to near the tips, where they have white and black annulations; from the outer surface of the fore legs, there is a reddish- brown wash, which extends over the shoulders, and nearly meets on the back, gradually fading into the colours of the back and neck. The hairs of the tail are black at the roots, then yellowish, then a broad line of black, tipt with white. The feet, on the upper surface, are grizzled with white and black. The sides of the face and chin are light grey. The whole of the remainder of the under surface of the body, including a line around the eyes, the throat and inner surface of the legs, is of an uniform bright rufous colour.

There can, how- ever, be no doubt, from its differing in so many details of colour, of its being distinct from either. Habitat. Northern parts of California. Sciurus molli-pilosus.

Tail shorter than the body ; back dark brown; sides of the neck and flanks rufous; under surface, cinereous. Form.— This species is a little larger than Sciurus Hudsonicus, with which we have compared it; its legs especially are considerably longer and more robust; the fur is much softer, the hair longer and less glossy than that of the former species. Colour.— The teeth are yellow; the upper parts, including the nose, ears and outer surface of the legs and upper surface of the tail, are dark brown. This colour is formed by the hairs being plumbeous at the roots, tipt with light brown and black. On the sides of the neck, the shoulder and near the thighs, the colour is reddish brown. The tail, which is not very dis- tichous, is brown, twice annulated with black ; a few of the hairs are tipt with grey. On the under surface, the lips, cheeks and chin are greyish- brown ; the inner surface of the fore legs, the throat and abdomen cine- reous, lightly tinned in some places with rufous. This species differs so widely in all its details, from Sc. Hudsonicus, that it is scarcely necessary to point out their distinctive marks of difference. The space occupied by the lighter colours on the under surface is much narrower than in the former species, nor is there, as in that species, any black line of separation between the colours of the back and under surface.

The ears, which are elliptical in shape and narrower than io most of our species, are thickly clothed with soft, fine hair on both surfaces. The tail is very long, and, instead of being distichous, as in most of the species, is in the prepared specimen perfectly round. The feet are clothed with hair, par- tially concealing the nails. The hair is longer, more diffuse, but not softer than that of Sc. leucotis. Colour. — The head, ears, upper surface of the legs, tail, and a broad dor- sal line, black. On the sides, the hair is plumbeous at the roots, then a liiae of brown slightly tipt with black. On the under surface, this species is dark brownish black, from the lips to nearly the extent of the jaws. On the throat, inner surface of the legs, and whole under parts of the body, there is a mixture of black and brown fur, giving it a dark, rusty-brown colour.

There are now no less than eight North American squirrels, which are either permanently, or in some of their varieties, black. The present cannot, however, be identified with any of our known species. It approached nearest to the black variety of the Northern Grey Squirrel, but is sufficiently distinct from that to entitle it to another name. The species in the Atlantic States have, moreover, never been found west of the Rocky Mountains, nor, indeed, have any but the Fox squirrel (Sc. capis- tratus) been observed to the west of the Mississippi river. Fuller descriptions, with an account of habits, accompanied by good figures of the above species, will be given in a work on the North American Quadrupeds, now preparing for publication. Mr. Haldeman submitted the following " Description of a new species of fresh water Shell." Cyclas (pisidium) dentata. — Shell ovate, olivaceous, inflated, umbones elevated ; medial and lamellar teeth well developed. Length 0.5 ; height 0.4 inch. Hab. Oregon : Mr. Nuttall.

Verbal Communications. — Mr. Haldeinan called the at- tention of the Academy to several specimens of Unio of vari- ous colours, principally green and brown, the former being referable to U. viridis of Rafinesque, the latter to U. Tappan- ianus, of Lea. Mr. H. contends that they are identical, because they pass into each other, both as regards colour and the peculiarities of the cardinal teeth, which are lamellar, and extremely variable in number and size. It was not necessary to add a synonym to the original name, as Mr. Conrad proposed the name sub- viridis (New Fresh- water Shells,) for the brown variety which he figured ; in the event of its proving distinct from U. viri- dis of the west. This method of proposing names is very proper, because it has a tendency to limit the number of synonyms which might might otherwise be inflicted upon the nomenclature of natural history. Some contend that the shell from the Susquehanna cannot be the viridis, because the latter has not been found in the west, its locality being Ken- tucky river, according to Rafinesque ; whilst the Tappanianus is found in the Susquehanna ; but Mr. H. has found unequi- vocal specimens in Pigeon creek, Kentucky, which cannot be distinguished from those found in eastern Pennsylvania. He has found a variety with a thick shell, in James river, Va. Rafinesque's name has been objected to, but one of the speci- mens exhibited presents as brilliant a green as that of Ano- donta cataracta, Say. Mr. Haldeman wished the fact to be recorded, that he had placed some living specimens of Western Unio, Unio rectus, triqueter, circulus, cylindricus, ovatus and others, in the Sus- quehanna, where no western species has hitherto been found, except U. viridis, Raf.

Description of several new species of Fossil shells from the cretaceous deposits of the United States. First series, — from Upper Missouri, It is now nearly forty years since Messrs. Lewis and Clark, in their expedition to the Columbia river, procured a few fossils at the great bend of the Missouri river, (Lat. 43° 40' N.) which I identi fied as belonging to cretaceous deposits of the same age as the Marl or Ferruginous sand of New Jersey, Delaware, Alabama, &c. Sub- October, 1841.] 107 sequently Mr. Nuttall brought some additional species, but for the most part in fragments. Very lately, however, Mr. J. N. Nicollet having personally visited that remote region, obtained a series of fossils in far greater perfection and variety than any previous tra- veller. It is proposed on the present occasion to indicate the species, and accompany them with a few brief remarks. Genus Ammonites. 1. A. mandanensis. — Shell compressed, with scarcely two volutions, the ioner being received into a superficial fossa of the outer whorl- Internal and external margins armed with pointed tubercles, between which are delicate, gently curved costas, mostly bifur- cated about one-third of the distance from the outer tubercles, beyond which they extend across the periphery of the shell ; the latter gently plano-convex. Umbilicus imperforate ? The diameter of the largest specimen has been about three inches ; of the smallest I have seen, an inch and a half. In the smaller specimeus the internal marginal tubercles are very indis- tinct ; but in other respects this species appears to be but little modified by age. •J. A. abyssinus. — Whorls convex, making two nearly complete volutions, with strong, gently curved, bifurcated ribs, slightly tuberculated at the margin of the dorsal periphery, which they cross to meet the costse of the opposite side. Umbilicus perfo- rate. Diameter from three-fourths of an inch to one inch. This species is strikingly different from the A. mandanensis, in the greater size of its costae, its perforate umbilicus, and its convex dorsal periphery. 3. A. borealis. — Shell convex, rapidly enlarging towards the mouth, with at least two volutions, one received deeply into the other ; costae delicate, gently curved, and bifurcate towards the convex dorsal periphery, which they cross in arched lines between numerous minute tubercles. Some years since I saw several specimens of Ammonites which were obtained by Judge Bry, in the township of Wachita, in Lou- 16 108 [October, 1841. isiana. I have elsewhere (Synop. p. 24,) considered them as indi- cations of cretaceous deposits ; and my recollection induces me to believe that their characters correspond either to A. Abyssinus or A. borealis. Besides the preceding fossils from upper Missouri, Mr. Ni- collet obtained the following species from the same interesting locality. Ammonites Conradi (nobis,) Synop. PI. xvi. fig. 1, 2, 3. Large and beautifully preserved specimens. Ammonites placenta, (Dekay,) Synop. pi. 2, fig 1. This species is found from comparatively small dimensions to a gigantic size, probably not less than two or three feet in diameter. Inoceramus Barabine (nobis,) Synop. PI. xvii. fig. 3, and PI. xiii. fig. 11. This shell has hitherto been found only in Greene county, Alabama, but appears to be abundant in the Mandan country, often compressed and broken, but readily identified. Baculites compressus, (Say,) Synop. PI. ix., fig. 1. This species so nearly resembles B. ovatus of the same naturalist, from the marls of New Jersey, that I am almost disposed to consider them identical. The species in question is found of gigantic dimen- sions, for example, more than a foot in length, and three or four inches in diameter. Belemnites Americanus, (nobis,) Synop. PI. 1, fig. 1, 2, 3. Hence it appears that among the small number of species no- ticed on this occasion, at least four are found in deposits of the same age on this side of the Mississippi, thus identifying the cretaceous strata over an immense geographical area, which commences in New Jersey, and perhaps at Martha's Vineyard, is traced in all the Atlantic States to Georgia, thence through Alabama and Mississippi, across the Mississippi to Louisiana, and Arkansas, where it is seen on the plains of the Kiamesha. From this point until we approach the Great Bend of the Missouri river, in the Mandan country, it has not yet been traced; but in the last named region, about 1500 miles above the mouth of the Missouri, it becomes again conspicuous as October, 1841.] 109 already stated, abounding in characteristic organic remains of great beauty. The extent of this locality is not yet known ; it is probable that it occupies a very large area, and is destined to become one of the most interesting and prolific fossil localities that has tempted the enterprise of geologists. These fossils are remarkable alike for their admirable preservation and their great beauty ; the latter being much heightened by the presence of an opalescent nacre which has been rarely noticed in the other cretaceous beds of this country. Second series, — from the lower cretaceous beds, or ferruginous sand of New Jersey and Delaware. Ammonceratites. A. Conradi. — Shell with an entire whorl, somewhat compressed, with numerous, distinct, slightly curved costse, which diminish and become almost extinct at the internal peripheral margin : external periphery sub-angular, and undulated by the transit of the costge. This specimen is a cast in a dark grey ferruginous sand, charged with minute scales of mica. The terminal end is nearly complete, and is almost on a line with what appears to have been the mouth of the shell, and the two approach within a quarter of an inch of each other. Diameter 2£ inches. This is the first example of an Ammonceratite found in the United States. It was obtained from a marl pit near Arneytown, New Jersey, by Mr. Conrad, in whose name I gladly introduce it to public notice. This genus is characteristic of the European chalk, having been found both in England and France, in deposits of that age ; thus affording another evidence of the analogy between the cretaceous deposits of the old world with the marl strata of the new. Hamites. H. annulifer. — Shell small, cylindrical, equal; the external two- 110 [October, 1841. thirds convex, the internal third coneave, with numerous delicate, distinct and closely approximated rings, which encircle the whole shell. One end of this remarkable species has the characteristic curve and septa of the Hamites. The concave surface looks as if de- signed to receive the cylinder of the opposite side. Length nearly one inch. Found by Mr. Conrad in the ferruginous sand at the Deep-cut of the Chesapeake and Delaware canal. STATED MEETING, October 19, 1841. Vice President Morton in the Chair.

Dr. Edward Hallowell read the following paper on a new species of Reptile ; viz. Description of a new species of Chameleon from Western Africa, by Edward Hallowell, M. D. Chamveleo gracilis. — Description. Head of moderate size, flat- tened above, depressed in front, presenting upon its upper surface a longitudinal carina, bifurcated anteriorly; each of the divisions resulting from this bifurcation, terminates near the posterior ex- tremity of the supraciliary ridge ; in front of the eye is a ridge continuous with the one above the orbit, extending toward the extremity of the nose. No denticulations are observed upon the supraciliary ridge, on the one just described, nor upon the longitu- dinal carina, or its divisions; but they are very distinct along the superior margin of the temples. A number of small tubercles are seen upon the face, quite near to the extremity of the nose, and also upon the sides of the head in front of the nostril ; a marked concavity exists upon the upper and posterior part of the head, immediately behind the bifurcation of the longitudinal carina ; the space in front comprised between the two branches is perfectly plane ; the head is covered above with polygonal scales of unequal size, and smooth for the most part ; those situated in the depres- sions upen the upper and posterior part of the head are somewhat ^4 112 [October, 1841. larger and more uniform in size than those upon the vertex and face ; scales upon the sides of the head of nearly uniform size, many of them tuberculated ; there are nineteen teeth on each side of the upper and lower jaw; scales upon the sides of the body of various shapes, some of them hexagonal, others pentagonal; the greater number are quadrangular : they vary also in size ; those upon the body, near the spine, are the largest ; some of the scales present a plane surface, others are more or less convex, and many on exami- nation with a glass are observed to have a very distinctly elevated point in the centre ; numerous small granules are interspersed be- tween the scales upon the abdomen; none are observed upon the sides : scales upon the throat irregular in size and shape, many of them tuberculated, those along the median line the largest; scales upon the abdomen granular, of nearly equal size, many of them presenting an elevated point in the centre ; those upon the under surface of the tail oblong, hexagonal, some of them pentagonal many of them with a depression in the centre; those upon the under surface of the hands and toes very distinctly quadrangular, arranged in transverse rows; extremities slender; tail somewhat longer (about a fourth of an inch) than total length of head and body. Colour. — The predominating colour is green, presenting different shades under different circumstances ; at times, the snout and mar- gin of the jaws, the neck, limbs and tail are marked with ferrugi- nous; and a narrow vitta of a light chocolate colour is seen extend- ing from the axilla to near the groin ; the whole of the body presents at times the latter colour, mixed with dusky green or fer- ruginous ; a triple row of black spots is observed upon the tail, extending from the root to within a short distance of its extremity; a similar row exists upon the back, corresponding with the trans- verse processes of the vertebrae : while one side of the animal pre- sents these shades, the other, or that which is less exposed to the light, is of a uniform pea-green colour, except the lateral vitta and a small spot above the shoulder, which are of a light flesh colour, and at times perfectly white ; on exposing the animal suddenly to the light of a candle, on one occasion, four or five irregular bands October, 1841.] 113 of a light chocolate colour were observed upon the body, extending from the back to the middle line of the belly, the intervening spaces as well as the bands themselves being marked with numerous dark coloured spots ; these bands often became dark green, the inter- vening spaces being a shade or two lighter ; seven or eight con- verging bands of the same dark green colour are observed upon the eyelids, their lower broadest part being directed towards the mar- gin of the orbit; pupil black ; iris golden ; under surface of belly, groins, axillae, as well as inner surface of extremities, whitish with a shade of green. The same banded appearance above described, was frequently observed when the animal was in exercise, as when employed in efforts to get out of its cage, or when allowed to walk upon the table or floor; when quiescent these bands were rarely noticed. On the 9th of July she laid twenty eggs ; these were per- fectly white, without spots, and of an oval figure ; for several days she had been restless, and was employed the greater part of the day in scratching in one of the corners at the bottom of the cage ; the coloration of the animal at this period was different from that noticed at any other ; the whole body presented a deep copperas green color, changing at times to a dusky brown : at times the body has a mottled appearance ; at others four or five dark coloured transverse bands were noticed, the intervening spaces, as well as the bands, presenting numerous light green spots upon a ground of dusky green ; on turning the animal suddenly round to the light, the side opposite to that described, appeared of a rich sap green colour, changing in a few moments to a deep bottle green, the transverse bands becoming less and less distinct; the spot over the shoulder and the lateral vitta were reddish brown : immediately after death the green assumed a yellowish tint, and two large blotches appeared on each side of the body of the colour of lamp black. Sept. 11, 1841. The animal has now been immersed in alcohol for more than a year, and presents a very different appearance from that which existed during life ; the head, sides of the body, tail and upper surface of extremities are of a light bluish or leaden colour; the dark coloured blotches upon the sides are visible, but 114 [October, 1841. much less distinct than at the time of the death of the animal ; throat, abdomen, and under surface of extremities and tail, whitish ; the spot upon the shoulder and lateral vitta are dirty white. Dimensions. Length of head, one inch (Fr.) : greatest breadth six lines; height seven lines; length of neck two lines; of body two inches eight lines ; of tail four inches seven lines ; of anterior extremities two inches ; of posterior one inch. (These measure- ments were taken after the specimen had been long immersed in spirits.) Habits. — The animal arrived in this city from New York on the 12th of June, 1840. During the first three days its appetite was good, spending the greater part of the time in catching flies by means of its long extensible tongue, which on one or two oocasions it was observed to protrude to the extent of nine inches. The motions of the animal were very sluggish, passing almost the whole of the day upon the perch of the cage in which it was kept, turning the eyes in every direction in search of flies, which were no sooner within reach than the tongue was protruded with the rapidity of lightning, and the insect rapidly drawn into the mouth. In the three or four following days, which were rainy and cold for the season, her appetite appeared to have failed ; during this time she was not seen to catch a fly, although many were quite near, but she often descended from the perch to drink; notwithstanding her indisposi- tion to eat, she would watch for hours the motions of the flies about the cage, the eyes preserving their accustomed brilliancy of ex- pression. On being placed upon a plane surface, she walked with more care, and often with more rapidity than might have been ex- pected from the pincer-like arrangement of the feet and bands, the fingers and toes being fully extended; but the usual manner of progression and general appearance of the animal when in motion, corresponded with the description of those given by Valisnieri. During the time that she was laying her eggs, she did not eat, nor had she taken food for several days previous ; she became greatly emaciated, and died almost immediately after their expulsion from the body. Habitat. — Liberia, in Western Africa. October, 1841.] 115 General observations. The specimen above described was pur- chased by the Rev. Charles Eden, of Monrovia, of one of the African natives, and sent to Dr. Blanding of this city, who, with his accustomed liberality, pi. iced it in my hands for observation and description. A drawing of the animal was recently shown to M. Bibran, of the Gardeo of Plants, by the artist who made it, who informs me that he considers it as new. *Dr. Goddard stated that he had examined the so-called " Missourium Kochii," and found it to be a skeleton composed of Mastodon bones, most of which appeared to belong to a single set, many, however, having been superadded, and others mended and glued together in a manner wholly errone- ous. The following errors were especially noticed: Spine. — The spine presented the anomaly of 8 cervical ver- tebrae ; and instead of 19 dorsal and 4 lumbar, had 23 dorsal and 10 lumbar vertebras, making the number of bones in the spine too great by 11. The bones articulated with the 2nd and 4th ribs were cervical vertebrae. The spaces between the vertebrae were much magnified by thick wooden blocks placed between them, and the spine was curved upwards, so as to give an exaggerated idea of the height of the animal. Ribs. — These were redundant in number, and were spread out as much as possible, so as to present the appearance of a wide and flat chest. The 1st pair of ribs were stuck on the bones of the shoulder, to resemble clavicles — bones which the Mastodon does not possess. Head. — The head was that of a Mastodon with the top de- ficient, and a piece of an ethmoidal ? bone glued on in front to *This communication was made to the Societyat the meeting of October 12th.

The tusks were distorted laterally, so as to occupy a space of 18 feet in width. Scapulae and ilia. — These having been deficient, were very ingeniously pieced out of wood, glued over so as to resemble bone. Feet. — The feet were ludicrously made up of carpal and tarsal bones, and presented the wonderful anomaly of 4 pha- langes to each toe. Several other discrepancies were observed ; apart from which Dr. G. considered the skeleton one of very great interest. MEETING FOR BUSINESS, October 26, 1841. Professor W. R. Johnson in the Chair.

Written Communications. — A letter was read from Dr. Frederick Tamnau, Jr., of Berlin, acknowledging the receipt of his diploma of membership in this Society, and soliciting an exchange of the minerals and fossils of Germany for those of America. Professor Johnson made some remarks on the samples of Anthracite from Rhode Island, this evening presented, and stated — That the formation in which they occur, reposes on a coarse con- glomerate, which rests immediately on granite or hornblende rocks of the primitive series. The near proximity of primitive rocks appears to have exercised an important influence, not only on the position, but on the present character of the anthracite of this for- mation ; for while it has thrown the beds into a highly inclined posi- tion, it has expelled the last vestiges of volatile matter, decomposed the sulphuret of iron, and changed the colour of the coal in some of the beds to a nearly steel blue. The vegetable impressions are in these cases to a great extent obliterated, and the traces of them only appear at the surfaces of deposition. In other beds, the im- pressions are more perfect, and their genera and species are more readily made out. An idea has been formerly current, that the coal formation of Rhode Island and Massachusetts is of more ancient date than those of Pennsylvania ; but the identity of fossil remains occurring in both, seems to determine the geological period of both to be the same. And in this respect we have analogies sufficiently numerous in our own country, to induce us to believe that all the coal forma- tions are essentially contemporaneous, and that whether they rest on November, 1841.] 119 granite, as in Rhode Island, Massachusetts and Virginia, on the older members of the secondary, as in the anthracite fields of Penn- sylvania, or on the mountain or the " cliff"" limestone of the western states, the coal series has every where been the product of a period in the history of our planet which was highly prolific in vegetable life, of which the remains were deposited on whatever member of preceding formations was exposed in a condition to receive them. The anthracite of Rhode Island appears to have been subjected not only to a high temperature, but also to intense pressure, and to have been much comminuted by the friction of one member of the formation sliding over another in the uptilting which the strata have evidently undergone. The coal in all such cases being more tender and friable than the sandstones, slates and limestones, becomes the unguent in the joints of the stratification, and the results of its power to facilitate the motions of the strata as they are partially folded up, is, 1st, a pulverulent portion in contact with either the top or the bottom rock of the bed ; 2d, a high polish imparted to some of the sliding surfaces of the more durable coal ; 3d, an irregularity in the thickness of the coal beds, the indentations of the upper and lower rocks being not unfrequently found opposite to each other, forming thick places in the coal seam, and containing much of the broken material which has been displaced from the parts where the promi- nences of the rocks come nearly in contract, and almost shut up the seam. Prof. Johnson adverted to the fact that for reasons stated by the geologists of Rhode Island and Massachusetts, viz. the great amount of drift or diluvial matter with which all parts of this coal formation have been covered over, the limits of the coal trough have not hitherto been traced with much precision. Within the city of Providence, the strike of the beds is a little to the east of south, and the dip of course to the north of east.

A letter was read from Dr. Frederick Tamnau, dated Ber- lin, Prussia, Dec. 20th, 1S41, proposing an exchange of mine- ral productions from Germany, Norway, Sweden, &c, for 25 172 [ May, 1842. those of this country ; and also appending a catalogue of the minerals at present in his possession. VERBAL COMMUNICATIONS. Dr. Goddard stated, that he believed the genus of Infusoria, referred to by Dr. Chaloner at the last meeting, to be Closte- rium, and that it possessed much resemblance to vegetable matter ; the most positive proof of which was, that upon the application of iodine to the interior of the supposed animals, a blue colour was produced. The evolution of oxygen gas was an additional proof of their vegetable origin. In reference to the donation of Fossil Woods made this evening, Dr. Goddard also adverted to the belief usually enter- tained of the Exogenous specimens being confined exclusively to the Coniferae, and observed that most of those on the table evidently possessed this character; others however belonged to the Endogenae. Mr. Gliddon entered into some particulars respecting the localities from which a large portion of the donations made by him this evening, was derived. Mr. Gliddon also, in reply to a request from Prof. Rogers for information respecting Boulder formations in Egypt, observed, that these Boulders were found about 200 miles above Cairo, scattered in great numbers over the Desert, lying upon limestone; and appeared to consist principally of sandstone, the surface being much darker than the interior of the stone. Mr. Gliddon having suggested to the Society, the advantages which it might derive for obtaining more defi- nite information on this and other geological subjects, from communicating with the Egyptian Society at Cairo, it was, on motion, liesolved, — That a Committee of three be appointed to May, 1842.] 173 draft a series of queries to be addressed to the Egyptian Soci- ety at Cairo, with reference to the geology of Egypt. The Committee consists of Prof. Rogers, Dr. Morton, and Mr. Taylor. The Society also passed a vote of thanks to Mr. Gliddon for his donation, and the valuable and interesting information afforded by him this evening. STATED MEETING, May 17, 1842.

Haldemon, Richard Wistar, and J. Price Wetherill. The subscription amounted to $325, of which a small balance remained unexpended, which it was proposed to appropriate towards the erection of cases for containing Birds. 176 [May, 1S42. In accordance with a suggestion from the Chairman, it was then on motion, Resolved, — That Prof. Locke have permission to take casts of the Fossils now in the Collection of the Academy. MEETING FOR BUSINESS, May 31, 1S42. Vice President Morton in the Chair. The Report of the Corresponding Secretary for the last month was read and adopted. The Committee to whom was referred the following com- munication from Mr. S. S. Haideman, read Feb. 1, 1842, re- ported in favour of publication in the Proceedings of the Academy. A spirit of selfishness has crept into Zoology, which looks rather to the advan- tage of the individual, than to the advancement of ihe science ; and authors, with the former point in view, have invented various methods to carry out the princi- ple; and, what is worse, authority brings those to practice them, who would have been shocked at the idea of using them in the first instance. Among these, I count the practice of citing one's own name for a genus or species founded by another, on the strength of varying a single letter, or even the gender. Examples of this occur in the writings of Rafinesque. If this is proper, a printer may as- sume the authoiship of a book in which he finds and corrects grammatical errors. Admit the principal that Unio metanevra, Kaf. shall be called U. metannever, Lea : and the French will have our own authority to assume almost every species of American Unio, because they consider them as of the feminine gender, whilst they have been described here as masculine ; and any one not a botanist, may place the species of Potamogston (heretofore considered neuter) in the feminine gender to which it belongs, as has been ascertained from a passage in Pliny. Having recently looked over the list of American Unionidffi, I wish to propose a few corrections in nomenclature, before they arc made, and the species appro- priated abroad, by someone who will not cite the original desciiber. A western con- cbologist gives all the species of Alasmodon to Mr. Lea, not because he was the first to name them, to create thegenu«, or to place them in it; but because he places them in the same genus with those who first described them, but under a differ- May, 1S42.] 177 ent name, which has neither priority nor sense to recommend it ; and which, under other circumstances, this author would probably have rejected, if we may judge from the fact that he adopts the names Physa and Planorbis, rather than Bulinus and Coretus. The same principle would deprive Mr. Lea of all his spe- cies of Alasmodon ; for assuredly authors will not adopt Shumacher's name (or this genus, when so much a better one is in general use. Generic nomenclature is not, and never has been, subjected to the rigid rule of priority which species require; and a name founded upon the generic peculiarity will generally be adop- ted in preference to others. A fossil animal with a head unlike that of a bird, was named Omithocephalus ; it is now called Pterod ictylus. A remarkable mammal with flat feet, and a bill like that of a bird, was first named Platypus, but is now- known by the name Ornithorhynchus* alone. To put these matters to the test. I propose that the letter u shall take the place of iv in the specific name of Unio Cowperianus of Lea, this gentleman having committed an error in the orthography. To suit the views of those who do not like the appearance of a name with the termination anus following a genitive, I propose that Couperii be adopted instead of the above. There is an " Anodonta Cowperiana" which I do not correct, because I wish merely to discuss a princi- ple. I propose that all the species of the genus Alasmoiionj- or Alasmodonta, be called by one of these names; and that the hybrid specific name of Unio Nash- ■villianus be changed into the more correct and classical one of Nashvicensis. Fi- nally, I disclaim all citation for these proposition*, as I think it would be the height of absurdity to cite any one for species he does not know. In relation to the communication of Dr. A. Clapp, of New Albany, Indiana, read March 8th, 1S42, the Committee con- sisting of Mr. Conrad, Prof. Rogers and Mr. Vanuxem, re- ported the following for publication in the Proceedings: — A letter was read from Dr. A. Clapp of New Albany, Indiana, dated February 25ih, in relation to the Geological equivalents of the rocks of the Falls of the Ohio, and other strata in the Western States. The author states, that, the'e appears to be little or no true carboniferous lime- stone east of the Falls of the Ohio. The stratum which he doubtfully referred to it, in a previous letter of December, 1840, viz the Oolitic and Pentremile lime- stone of Professor Troost and Dr. Owen, he is now convinced is the carboniferous limestone, commencing a short distance west of New Albany, and underlying the coal formation in the western part of Indiana, part of Kentucky and Illinois. It is entirely wanting in Ohio. He refers to his previous communication of April last, as showing that the limestone of the Falls of the Ohio, the cliff limestone of Professor Locke, does not belong to the Carboniferous, but to the Upper Siluiian System of Murchison. The limestone of the Falls immediately underlies the black bituminous slate, which appears to be the equivalent of the Marcellus shales of New York. The lower strata of the Falls have many fossils of the Weulock limestone, but the * The middle h is sometimes omitted, as it was by Linneus in his genus Ryn- chops. Is the first author who made the omission, and he who first wrote Rliyn- chops, entitled to these genera, with their species ? In a notice of Kiener's work, in the Re\U' Zoologique, this author is censured for writing " Pleurotonia mitrs% formis Fell," Wond having previously used the specific name " mitrj'formis." j This ;s the more correct form, and corresponds with .Mono. Ion, Ifvodon, Dio- don, etc. 178 [May, 1S42. upper, particularly the water lime, has also many of the Ludlow. The lower and middle portions of the Cliff limestone, he conjectures to be equivalents of the Ni- agara limestone and Gypseous shales : the entire mass called the Cliff limestone, represents therefore the Niagara limestone, Gypseous shales, water-lime, Ononda- ga limestone, &c. to the Marcellus shales. Under the name Cliff limestone is here included all the group above the blue limestone and marls of Cincinnati, to the black slate. It is the western continuation of the middle Silurian series of Mr. Conrad. The water-lime of the Falls of the Ohio, is a drab-coloured rock, from ten to fourteen feet thick, covered by a subcrystalline foetid limestone eight feet thick, containing Enerini, a Conu/aria, Delthyris and Favosites, and a few other co- rals, and immediately underlies the black slate. In mast places the water-lime is entirely destitute of organic remains ; the few which occur belong to the lower Ludlow and Amestry of Murchison, as Orthis hmata vel reticularis, leptxna lata ? Turbo carinatus, Terebra sinuosa, Tentaculites, perhaps a new species, ■Avicula reticulata, Calymene bufo, Aaaphus Micrurus; several undetermined species of Delthyris, an Eschara, &c. In the strata below the water-lime were f mnd many fossils of the Wenlock limestone, Strophomena euglypha, Atrypa prisca, the latter also occurring in the water-lime and upper limestone; Pleurorynchtts cureous? of Conrad, and an immense profusion of Polyparia, characteristic of the Wenlock limestone. The Catamepora occurs below the main mass of the corals, and thirty or forty feet below the water-lime. It would therefore appear, that the water-lime belongs to the middle or upper part of the Hederburg group, and cannot represent the Onondaga salt group of Mr. Hall. The author expresses a doubt of the identity of the black bituminous slate of Ohio, with the Ludlowville group of Mr. Hall, as supposed by that gentleman. Though the shales and sandstone in the vicinity of New Albany, for more than four hundred feet above the black slate, are destitute of fossils, except a few in- distinct Fucoides, yet sixteen miles south, in Kentucky, great quantities of Cri- noidiea occur, fifty or one hundred feet above the slate; and an Orthis which Mr. Hall consideis identical with a species of the Ludlowville shale of New York.

The Chairman read a letter from Mr. S. S. Haldeman, dated Marietta, Pennsa., May 17, 1842, enclosing communications intended for publication in the Proceedings of the Academy, viz : descriptions of a new Species of Cypris, of two species of Hydrachnse, and of two Entomostraca. In this letter Mr. Haldeman stated the singular fact of his having observed, " in a small pond two feet in diameter and two inches deep, no less than thirty species of animal form ; including two Crustacea, four Entomostraca, nine Mollusca, one Annelid, two Hydrachnas, and about a dozen aquatic larvae." The communications were referred to a committee, consist- ing of Mr. Phillips, Dr. Goddard and Dr. Morton. A letter was also read from Dr. Corson, dated Conshehock- en, June 10, 1842, accompanying his donation. VERBAL COMMUNICATIONS. Professor Rogers called the attention of the members to the recent earthquake in St. Domingo, remarkable for its severity and the great destruction of life and property. He alluded to 182 [June, 1842. the evidence which the recent accounts from the West Indies furnish, of the general correctness of the hypothesis, originally advanced by Michell, in the Philosophical Transactions for 1760, that the movement of the earth in earthquakes is undu- latory. That such is the nature of the motion may be con- sidered indeed as established, both from observation in many regions of the globe, and from instrumental investigations now in progress in Scotland. Professor Rogers proposes to explain the billowy oscillation of the ground, by actual waves engendered on the surface of the great fluid lava-mass, sup- posed to occupy the whole interior of the globe ; and he ac- counts for the waves, by the sudden or explosive escape of highly compressed vapours, by the rending of the crust, or through other outlets. He suggested to the Society the importance of procuring, through correspondence on the part of members, some more detailed and accurate statements than have yet appeared in the public prints, in relation to the phenomena of the late shocks in the West Indies ; as regards, First. The extent of the earthquake ; whether it reached the mainland of South America, and to what distance north- ward from Porto Rico and St. Domingo it was felt at sea. Secondly. The direction of the undulations and accompa- nying concussions. Thirdly. The precise time at each locality of the occur- rence of the first shock, and of each principal succeeding one. Fourthly. Whether the cloud of vapour reported to have been seen at Port Plate, on the north-east coast of St. Domin- go, was actually such, or merely dust, caused by disturbance of the soil or the crushing of falling buildings.

Dr. Goddard remarked, in reference to the inflated lung presented this evening, that it offered a very good type of the lobule of the human lung ; and that although each lobule of the latter was isolated and distinct from all the rest, its air cells communicated freely with each other; a fact, the discovery of which was due to Professor Horner. 184 [June, 1842. MEETING FOR BUSINESS, June 28th, 1842. Vice President Morton in the Chair. The committee, consisting of Mr. Phillips, Dr. Goddard, and Dr. Morton, to whom were referred the following communica- tions of Mr. Haldeman, reported in favour of publication in the Proceedings. Description of two species of Entomostraca and two Hy- drachnae, by S. S. Haldeman. Daphnia abrupta. Body short, irregular in outline, back but slightly convex, meeting the head at a slight depression, and the posterior extremity with a curve of a quarter of a circle ; posterior margin running downwards and forwards, with a rounded projection opposite the head ; ventral margin very convex.

The Corresponding Secretary read a note from Dr. Richard Harlan, in relation to a donation of Fossils intended for the Academy, now in his possession, from Mr. Couper, of Georgia. The Chairman read a letter from Prof. Locke, dated Medical College, Ohio, June 18, 1842, stating that specimens of the fossil Cryptolithus tesselatus, had been discovered in his neighbourhood, in marl, which display the abdominal portion, not hitherto detected in this species, and containing a description and drawing of the same. Referred to a committee composed of Mr. Haldeman, Mr. Phillips and Dr. Morton. Professor Johnson read a communication from Peter A. July, 1842.] 187 Browne, Esq. containing a description of a monstrosity occur- ring in a species of Rose, in which a portion of the inflores- cence had been superseded by a growth resembling a brand) with its leaves ; with some explanations as to the mode in which this anomalous condition was produced. The communication was referred to Drs. Pickering, Bridg- es and Zantzinger. Dr. Chaloner read a translation from the French of M- Linant's account of the discovery of the Petrified Forest near Cairo, Egypt, with a description of the same. Specimens from this forest were presented by Geo. R. Gliddon, Esq. at a former meeting of the Academy. On motion, Resolved, that a copy of this translation be placed in the Library of the Academy. Mr. Haldeman read a paper, entitled " A Description of two new species of Hydrachnae ; viz. H. nebulosa, and H. cocci- nea ; and of one Daphnia, D. reticulata," which was referred to a committee, consisting of Drs. Goddard, McMurtrie and Pickering. VERBAL COMMUNICATIONS. Professor Johnson made some remarks on the determination of copper in analysis. He stated that the usual mode was to pre- cipitate the protoxide from solution; that in this case, it is neces- ary that an excess of alkali should be added, and the precipitate well washed. It is also attended by a loss in filtering, &c. By using dry sulphate of copper these objections are obviated. This salt is readily dried without decomposition; and Professor Johnson stated that with the same portion of copper he re- peated an experiment several times, and had found this mode of determination more satisfactory than that by the oxide, and with less variation in result. Mr. Haldeman then made the following remarks. From the great number of generic names required in Zoolo- 27 188 [July, 1842. gy and Botany, it frequently happens that the same name will occur, not only in both these sciences, but will be occasionally used for different genera in one or the other kingdom. No principle is perhaps better established than that which denies the same name to different genera ; and it is necessary, there- fore, that those concerned in the construction of generic nomenclature, should look over the names already instituted, as a safeguard against a double emploi. Thus Cenchrus and Apogon are genera in both kingdoms. I wish, therefore, to propose a few changes in the names of several genera, viz : Anojmia, instead of Harpyia, Cuv., for a genus of birds, the latter name being preoccupied, both in Mammalogy and En- tomology. Oplacerus, instead of Mazama, Smith ; this name having been pre-applied to Ovis or Capra montana, Ord, by Rafin- esque. Sargus, was long since applied to a genus of dipterous in- sects by Illiger : Cuvier more recently, upon dismembering the genus Sparus of Artedi and Linnaaus, improperly adopted it for the typical section, to which, therefore, the original name Sparus must be applied. Lynx, (a subgenus of Felis,) was published by Rafinesque in 1817, and I believe has the priority of Lynchus, which is also the name of a genus of Crustacea. STATED MEETING, July 12, 1842.

DONATIONS TO LIBRARY. Syllabus of a course of popular lectures on Physiology. By Reynell Coates, M. D. From Mr. Haldeman. American Journal of Science and Arts. Vol.43, No. 1. For April, May and June, 1842. From the Editors. WRITTEN COMMUNICATIONS. Mr. Haldeman read the following additional Remarks on Changes of Nomenclature in Natural History, which were referred to Dr. Morton, Dr. Bridges and Mr. Phillips as a committee, who reported in favour of publication in the Pro- ceedings. * Since described by Dr. Harlan, at pp. 143, 144, of Silliman's Journal for July 1842, the former as the left ramus of the lower jaw of Sus Americana, and the latter as the right os fomoris of Chelonia Couperi. July, 1842.] l^J In continuation of my observations on the use of the same name for different genera, I would remark that it is possible, in many instances, to vary the later one so slightly, that it would be essentially the same; and, to prevent confusion, the name of the author who instituted the genus, might be cited for it.* These variations might take place either in the orthography, in the gender, or by a diminitive. Linnams himself has set us an example, in applying such names as Picus and Pica to distinct genera of birds. But in making changes of this kind, it is very necessary to be careful that great confusion be not the result. Thus, Bonaparte has proposed '■ Pogonathus, Bon." in place of" Pogonias, Cuv." because the latter is applied to a genus of birds. Yet if we turn to the Regne Animal, we will find " Pogonias' Lacep." We do not, however, find Pogonias in Lacepede, the name being Pogonathus. I propose Ancyllus and Teronyx, instead of Ancylus and Trionyx, for genera of Hymenoptera. Conoura, Eucryptus and Auchenella, instead of Conurus, Cryptus, (Hal.) and Auchenia, for genera of insects. Clypastrsea and Strong ulus, instead of Clypeaster and Strongylus, for coleopte- rous genera. Cymindus, instead of Cymindis, for a genus of birds; and Labeola instead of Labeo, for a genus of insects. There are many other names employed for dis- tinct genera ; thus Chione, Venilia, Cleodora, Pandora, Hyria and Lucina, are common to conchology and entomology ; Sylvia and Tanagra to the latter and ornithology ; and Labeo and Zytena to entomology and ichthyology. The following " Note on the Natural Alliances of the genus Cecidomyia, intended to facilitate identification ;" was read by Dr. B. H. Coates, and referred to a committee, viz. : Dr. McMurtrie, Dr. Pickering, and Mr. Haldeman ; who reported it for publication in the Proceedings of the Academy. Nothing new is professed to be furnished by the present paragraphs. They are compiled from sources not difficult of access among the liberal collections of this city ; but it has been hoped that some utility could be derived from preserving and more widely diffusing a memorandum of the^alliances of this destructive family of insects, so as to increase the number and practicability of observations on the part of those favourably situated for that purpose. The old Linnean genus, Tipula, is, I believe, a natural one. It is, at all events, one of a striking appearance. A delicate, lightly framed, two winged fly, of a form much resembling the moschito, frequently capable of resting and dancing on running streams of water, so as to attract popular attention by the circumstance, and at the same time unable to inflict severe and penetrating wounds on the bodies of warm-blooded animals, from the feebleness of its proboscis. This organ would seem, in general, only fitted for sucking up uncovered or but slightly covered fluids ; and contains, to use the language of one of the best authorities, only a pair of lan- cets ; being, in this respect, very deficient when compared with the allied family, Culicida;. The antennae, with the exception of a single sub-family, are thread- shaped. The perfect insect shows but little avidity for food. Five natural groups seem to arise; in each of which the appearance of the per- * Cuvier writes " Machoera, Lacep." but this genus stands Makaira, in Lacepede's work, and it is the more necessary to retain the original orthography, as Machcerahas been recently applied to a genus of Mollusca. IV 192 [July, 1842. feet insect visibly differs, and the habits of the larva vary materially in respect to food and habitation. We copy some of the characters. 1. Chirnomides. Aquatic Tipulides. Male antennae plumose ; larva) aquatic. 2. Tipulides proper. Terrestrial Tipulides. Head elongated into a muzzle; no ocelli ; larva? inhabit the earth. 3. Mycetophilides. Tipulides of fungi. Two or three ocelli ; trochanters elongated ; tibiae strongly spurred ; larva? feed on fungi. 4. Cecidomyides. Tipulides of gall-nuts. Head not prolonged into a muzzle ; no ocelli ; trochanters of ordinary length ; antenna? moniliform ; larva? feed in galls formed on vegetable substances. 5. Bibionides. Tipulides of flowers. Antenna? short, perfoliatcd, generally fewer than 12 joints ; legs of ordinary length ; larva? often resident in rotten dung and vegetable debris. [To me, this seems contradictory.] The above classification is quoted from M. Latreille ; and is preferred by the author whom I have already cited, and whom I believe to be Mr. Westwood. The less extensive knowledge of the species possessed in the years when Messrs. Meigen and Lamarck wrote, prevented their distribution of the family from being, at that time, so perfect. They are compelled, in this place, to follow a more artificial method ; and have thus brought in close approximation some animals whose mode of life has subsequently been thought to differ. It has since been thought to be rendered evident, that the larva? of the proper tipulida?, at least as a general rule, live on the roots of plants. Among the authorities cited for this are Kirby and Spcnce. It is evident that the natural affinities of Cecidomyia, are with the sub-family to which it has given its name. It has been approximated to Lasioptera. The latter is a genus with terrestrial larva?, living on roots ; and the parent, according to professor Meigen, not furnished with an ovipositor. The figures, too, given by the latter writer as specimens of the genera, differ in their habitus. In the earlier state of knowledge in relation to the tipulide tribe, and particularly while the lar- va? were less known, the collocation of several species was doubtful. Mr. Meigen is said to place the tipula juniperina L., which inhabits the tops of the juniper, " doubtfully in Lasioptera." 1 understand the words " unbekannte horde," under which he introduces this species, to mean " unknown, or ill-understood horde," or " unknown, ill-defined group." it is observed that every larva of the family, thus fur, appears to consume solid substances by chewing, and, as a necessary inference, to possess real jaws; instead of sucking by a trunk, as has been, in this country, universally affirmed of the species so frequently the subject of popular discussion. The consideration goes to strengthen, if possible, the inference that the quiescent substance generally sup- posed, in imitation of Mr. Say, to be the larva of the Hessian fly, and which, by the avowal of that distinguished writer, so closely resembles the pupa, is really the pupa in an earlier stage, and that the larva is to be looked for in the maxillated and gnawing worm. It appears to be every where observed, that as soon as these animals increase to a certain extent, their further diffusion is immediately limited by the ravages of the different parasites of the families Chalcidida? and Proctotrupida?. The coincidence of these diminutions, from a cause not generally understood, with various other circumstances affecting the wheat crops, probably gives reputation to many other supposed means, natural and artificial, of destroying the injurious The Corresponding Secretary read several letters from Mr. Couper, of Georgia, addressed to Dr. Harlan of this city, in July, 1842.] 193 reference to his donation of fossil bones and shells of this evening; and also containing a list of the specimens. VERBAL COMMUNICATIONS. Dr. Chaloner exhibited a specimen of a small Trilobite, said to have been taken from a coal excavation at the Bear Gap, about 14 miles from Pottsville, Pa., along with the fern im- pressions so numerous in such excavations. Some doubts were expressed by Dr. Chaloner as to the correctness of his informant. He was desirous, however, of calling the attention of the members to the subject. In relation to the donation of Minerals this evening, Mr. J. A. Clay remarked, that they exhibited in a striking manner, the identity of certain Magnesian minerals of the U. States, and especially of those of Chester county, Pennsylvania, with the Picrosmine, Metaxite, &c. of Europe. BUSINESS BY SPECIAL RESOLUTION.

The Chairman read two letters from M. Henry Galiotti, dated Brussels, Dec. 27, 1840, and Feb. 24, 1842, tendering his services in adding to the collections of the Society in the different departments of Natural History ; and soliciting ex- changes from the Academy, and from the members indivi- dually ; and also announcing that he had forwarded for the Society several of his works. By permission of the Academy, Professor H. D. Rogers, from the committee appointed in May last to draft a series of July, 1842.] 195 queries to be addressed to the Egyptian Society at Cairo, in reference to the geology of Egypt, and especially Boul- der formations, made a report on the subject, containing said queries. The report, on motion, was adopted. A communication from Peter A. Browne, Esq. was read, informing the Academy of his intention to present a valuable collection of West Indian Plants, Fruits and Seeds. On motion of Mr. Phillips, it was Resolved ; That the thanks of the Society be presented to Mr. Browne, for the very val- uable and finely preserved collection of plants, fruits, &c. obtained by him during his recent visit to the West Indies, and presented to the Academy this evening. 196 [July, 1842. MEETING FOR BUSINESS, July 26, 1842. Vice President Morton in the Chair. After the reading of the Monthly Report of the Corrrespond- ing Secretary, the following reports of committees were pre- sented and adopted. The Committee on the following paper by Mr. Haldeman, read July 5th, 1842, in favour of Publication in the Proceed- ings. Description of two new species of Hydrachna and one of Daphnia. By S. S. Haldeman. Hydr. nebulosa. Globular, mottled with brown ; a large central sub-rectangu- lar spot back of the eyes, which are apparently double upon each side, red and black ; an orange spot in the centre of the back ; legs very slender, first and second pair thinner than the third and fourth ; palpi long, basal half cylindrical, extremity tapering. More globular than my Unionicola oviformis, with a nearly similar light Y shaped mark upon the back, and equalling this species in size. Hab. A little pond on the Susquehanna, above Columbia. Hydr. coccinea. Subglobose, uniform bright scarlet, legs slender, covered with short bristles ; palpi bristled, ante-penultimate articulation thickened. Length 4 millim. Hab. with the preceding. Differs from H. scabra, in being larger, and in wanting the long bristles to the legs. The posterior legs are not " destitute of cilia," wherein it differs from Limnochares cxtendens, Say. Daphnia reticulata. Ovate, margins imbricated, surface divided by fine lines into minute rectangles; posterior half of the body with the dorsal and ventral por- tion approaching each other by similar curves, which meet in a long, slender, tapering caudal appendage. Closely resembles " Monocculus pulex." Jurine's Hist, des Monocles, PI. 8. fig. 1. Length 1£ millim. Hab. with the preceding. The Committee on Professor Locke's communication, read July 5th, 1842, on the Fossil Cryptolithus tesselatus, re- ported also in favour of publication in the Proceedings ; viz : So rarely do we meet with Fossils in such a state that we can unravel in any degree the structure beyond the mere external form, that I sit down while the subject is still new and exciting, to communicate to you what seems to me to be a discovery in relation to the Cryptolithus tessellatus. This fossil is so seldom found with anything more than the scuta and its ornamented margin, that some natu- ralists have doubted the existence of an " abdomen" and " tail," similar to the cor- responding parts of other trilobites. In examining a stratum of clay-marl which July, 1842.] 197 constitutes, perhaps, a hundred feet in thickness of our horizontal strata, the fos- sils were found to be merely imbedded, without petrefaction, and easily separable from the fine, soft, earthy matter. In this condition, they exhibit a freshness and sharpness highly interesting to the student. Within the last week, Mr^sJames Foster, an amateur collector of our city, discovered in this marl several specimens of the above fossil, with the body entire. Soon after, Mr. Anthony and myself found other specimens of the same. The new facts disclosed by these specimens and by others found in this vicinity, are 1st. That the animal was furnished when entire, with very long spines or processes from the posterior angles of the shield. 2d. The abdomen is partly concealed, about five articulations, under the poste- rior half of the shield. 3d. The middle lobe of the shield is posteriorly mucro- nate. The first fact is fully exhibited in a specimen in Mr. Foster's cabinet ; the second fact in a specimen of my own, in which the shield lias separated from the body, disclosing the articulations beneath ; the third fact in two specimens be- longing to Mr. Foster. The middle lobe of the abdomen is about half the width of the lateral lobes, and shows only five or six articulations uncovered by the shield. The tail is very distinct from the abdomen, with about five obscure articulations. Mr. Anthony has a specimen, which by a fracture of the shield, discloses seven abdominal articulations, and the whole number is probably ten. It is evident, from this structure, that when the animal rolled itself in the manner of the trilo- bite family, the whole body would be concealed under the shield. The posterior part of the body is circumscribed by a well defined raised margin. The associated fossils are Strophomcna alternata, Atrypa tcstudinaria, Lingula , Orbicula, Isotelus megistos, Calymene senaria, Grthocerce, Enchrinites and Corallines. Formation, " Blue limestone," Trenton Limestone of the N. Y. Geologists, or a formation above it. The Committee, to whom was referred the communication of P. A. Browne, Esq., describing a " monstrous Rose," made a report, stating that the difference in the character of this paper from the usual one of those inserted in the Journal cr Proceedings, and the necessity for the aid of a plate for its complete elucidation, rendered its publication, in its entire form, impracticable. The following, however, being the concluding portion of the paper, containing some strictures on terms used in Vegetable Physiology, the Committee recommended for publication in the Proceedings. It remains only to note, that when botanists inculcate the doctrine to which allusion has been made above,* they make use of terms that are illy adapted to convey their meaning. " A flower" they say, " is a transformed branch : all its organs being leaves, which have undergone a peculiar metamorphosis ,"t by which we would understand that nature first formed a branch, and afterwards converted * The present theory, of the flower being' the product of successive whorls of leaves. t Gray's Botany, p, 158, 198 [July, 1842' it progressively into a calyx, a corolla, stamens and pistils ; whereas they do not intend to be understood that these parts ever existed as branches or leaves, but that their nature and origin are the same. And this being the case, why are the wordslfrtransformed," and " metamorphosed" used at all ? Terms should never be used in science with different meanings from that in which they are generally understood, if it can possibly be avoided. ! ■ It is the opinion of some eminent botanists, that the same vegetable matter which, called into action on the earth, with sufficient light, air, &c. produces a Lichen, will, in moisture on decaying organised substances become a Fungus ; or if developed under water, exhibit the form of an Alga. But this has not been considered a sufficient warrant for the assertion, that one of these is transformed or is metamorphosed into the other. This erroneous mode of expression is peculiarly conspicuous in regard to the present specimen, since it conveys the idea that the leaves were first transformed into calyx, corolla, stamens and pistils, and were afterwards by a retrograde move- ment metamorphosed back again into leaves ; when in truth all we mean to assert is, that owing to the peculiar circumstances attending the developement of the flower, the vegetable matter which was called into action, never arrived at the stage of perfection required for these more perfect organs, and that therefore they remained leaves. The Society then proceeded to an election for Correspon- dents of the xA.cademy, with the following result. CORRESPONDENTS. Professor John A. Warder, of Cincinnati, Ohio. John C. Warren, M.

The Chairman read a note from Dr. Edmund Ravenel, dated Charleston, S. C, August 21, 1842, alluding to a fossil Scutt'lla, regarded by him as probably new; accompanied by sketches and a partial description of the same. VERBAL COMMUNICATIONS. Prof. Johnson exhibited and explained a method of applying the galvano- meter to the purpose of testing the relative deductibility of different samples of sheathing copper when exposed to the action of salt water. He referred ;o tin1 faci that, in early periods of the use of copper fur sheathing the bot- toms of vessels, while iron bolts were still used for fastenings, the copper lasted much I •> • >t than al present, while the iron itself was rapidly corn de I; thai pper bolts having been substituted for iron ones, the sheathing exhi- bited :i much more rapid decay than befi .>•. He likewise alluded i<> the fact that the practice of fastening on sheathing copper with composition nails, oilers an antagonist electric force to thai i*t' the copper, rendering the latter more highly electro-positive, and thus facilitating its union with the electro- negative elements of sea water. It was also mentioned, that in removing the copper from ships some sheets are often found much more corroded than the rest, and that this takes place among sheets manufactured at the same works, and apparently with equal care in freeing the metal from impurities. It v as further mentioned tiiat long experience had evinced the uncertainty ■ if obtaining durable copper by efforts to approximate chemical purity in the manufacture, and that in copper free from other meinls the oxide of copper is sometimes detected both in the interior and on the exterior of the mass, rendering it earihv in appearance, and liable to be disintegrated as well as corroded. In proof of this latter effect he exhibited a quantity of copper particles brushed from a sheet o\ that metal which had been worn 'several feare between the keel and the false keel of an English s|Uop of war, where, though ihe salt water could penetrate and corrode it, the disintegrated parti- cles coul I not be reached by the waves to be washed away. A> the comparative electric energy of two sheets of copper is proportion to the amount of corrosion going en, and as the quantity of electricity i motion also determines the influence of its current on a magnetic needle, the leflection id' that of a common galvanometer may be made to determin relation of two sheets to each other, and thus io ascertain whether they are uitable to lie associated together on the bottom of ihe same vessel. Two methods v. ere described and illn- trated by h hich this may I"' accom- plished. The fust is to oppose iii succession the several sheets of copper t>> a .sheet of platina constituting the negative element of the pair, and observing Sbpti mi , 1842.] 211 e • ■ • ch the several copper shi i n the Medl nf the i her i* to ippose .1 1 . ti»» -heei* ol sheathing ei ppi 1 ■ pore coppei dep the galvanotype 1 • n ii 1 were exhibited in connexion wnh several i\ iih nng copper, the specimens which had, by analysis, been shown u le purest copper, exhibiting the highest electro-positive energy when < im pared with platma.and ilie lowest electro-negative power when oppn.sed lo the galvanotype plate. Composition nails were found near platina in the scale, and galvanotype copper not so widely removed from iron as are some varieties of brass. The arrangement of apparatus supposed to be best adapted for use in prac- tice, is a triple astatic needle, having its middle needle w ithin, its lower one below, and its tipper one above a spiral of copper ribbon, formed in such a manner as to present the edges of the ribbon lo the upper and under surfaces of the needles. The suspension may be either that of a pivot, or that of a single or double support of unspun silk. The liquid preferred for use, in tins species of lest, is ci minoti sea water; being the same to which practice subjects the sheathins copper, and having the advantage ol being easily pro- cured, costing nothing, and capable, therel re, ol being renewed as often a.-- the operator may think' (it.

WRITTEN COMMUNICATIONS. i A communication was read by the Recording Secretary from Mr. Isaac Lea, dated October 31, 1842, correcting an error committed by Mr. Haldeman in a communication made by the latter to the Academy in May last, and pub- lished in its Proceedings, in which he proposed that " the letter u should take the place of w in the Unio Cowperiana of Lea," on the ground of an error in the orthography. Mr. 31 216 [November; 1842. Lea stated that the Unio in question was not named after Mr. J. Hamilton Couper of Georgia, as was probably sup- posed by Mr. Haldeman, but after Mr. Wm. Cooper of New York. Mr. Lea also objected to any change in the specific name, and also to Mr. Haldeman's proposed alteration of Unio Nashvillianus to U. Nashvicencis, the latter, in his opinion, not being " more classical and correct." The Corresponding Secretary read a letter from J. Hamilton Couper, Esq., of Darien, Georgia, dated Oct. 6, 1842, acknowledging the receipt of his notice of election as Correspondent of the Academy; and also transmitting a communication giving a detailed description of the strata, in which the fossil bones and shells from the Brunswick Canal, lately presented by him to the Academy, were found; preceded by a sketch of the geological features of the sur- rounding country. The communication was referred to the Committee on Proceedings. [The length of this interesting paper will preclude its in- sertion entire in this publication. It will be reserved for the first part of the next volume of the Journal of the Aca- demy. For the present, therefore, the Committee are only enabled to give the following, being the concluding portion of the paper.] The fossil bones of the terrestrial mammalia* were found in the bed of the canal, at the southern end of this swamp, at six different points extending up from its junction with the salt marsh to a distance of three miles. In every instance they were found at the bottom of the alluvial deposit, imbed- ded in it, and lying on the stratum of sand. The first two feet of the allu- vial formation is a sandy loam, gradually passing into a compact clay of a ferruginous character, which extends three or four feet deeper. In this stratum of clay thin veins of marl and fragments of petrified wood were found at different depths : but no fossil shells, either of marine or fresh water origin. The stratum of sand on which the bones were found lying is on an average nearly five feet above spring tides. About the line of * The most interesting of these bones belong to the Megatherium, the Mastodon giganteum, Elephas primogenius, Hippopotamus, Horse, Bos, and to a nondescript animal, which Dr. Harlan has described as the Sus Ameri- cana, in Silliman's Journal, for July, 1842. November, 1842.] 217 high water the sand changes its color from yellow to white, and assumes a quicksand character, which it retains for one or two feet, when it is suc- ceeded by a coarser and sharper sand, with the occasional occurrence of thin strata of foetid black mud or clay. Small masses of marine fossil shells,* lying horizontally, or nearly so, are found scattered at intervals throughout this sandy formation, at almost every point of the canal. The depth varies from five feet above to five feet below the line of high tides, — which is the greatest depth to which the excavation has extended. The rib and vertebra of the whale were discovered near the northern extremity of the swamp, in the yellow sand, and about a foot below its sur- face. They were much worn, and one of the vertebra was much incrusted with barnacles. At this point bog iron ore and protophosphate of iron were found above the sand containing the marine shells. The precise spot where the extinct Chelonia (C. Couperi of Harlan) occurred was not ascertained; but there is every probability that it was taken from the same formation. The bones of the mammalia occurred generally in groups; and in some cases a large number of those of the same skeleton were found together. From this circumstance and the unworn and perfect state of many of the bones, it is highly probable that the carcasses of the animals were floated, or fell into the then lake or stream, and that, sinking to the sandy bottom, they were gradually covered to their present depth by the deposits of the sediments of the water. Of the species discovered, the remains of the Megatherium and the Mammoth were.the most abundant; and of the former six heads of femurs were found in the bed of the canal within the distance of a mile. All the bones were at the same depth, and imbedded in the same stratum; thus leaving no doubt of their co-existence at a period suc- ceeding the elevation from the ocean of the newer pliocene, but antece- dent to the formation of the older recent alluvium of this coast. The co-existence of the Megatherium with the Mastodon, Mammoth, Hippopotamus, Horse, Ox, and Hog, has here, it is believed, been for the first time established; and forms, with the discovery on this continent, of a well defined fossil species of Sus, two interesting facts in Geology. The identity of most of the fossil shells which were found below the bones of the mammalia with the existing species on this coast, proves that the temperature of the ocean, long prior to the existence of the Me- gatherium, Mammoth, and Hippopotamus, was such as is congenial to the present mollusca. Another inference which may be^drawn is, that the surface of the country has undergone no sudden or violent change since these gigantic animals occupied its forests and morasses; but that such as have occurred have been slow and gradual. * The following species occur most abundantly: Venus mercenaria, Pyrula caurica, Cardium ventricosum, Artemis con- centrica, Area pexata, Area ponderosa, Lucina divaricata, Modiola late- ralis, Tellina alternata, Mactra lateralis ? Oliva literata, Natica duplicata, Crepidula convexa. 218 [November, 1842. STATED MEETING, November 8, 1842, Mr. Phillips in the Chair. DONATIONS TO MUSEUM.

VERBAL COMMUNICATIONS. ' Prof. Johnson mentioned that he had made trials to'determine the vola- tile and earthy ingredients of the so-called natural coke from Virginia, of which samples were exhibited at a preceding meeting of the Academy. This substance presents in its exterior appearance a strong contrast with all known varieties of either anthracite or bituminous coal. It is wholly wanting in lustre. It has lost, if it ever possessed, all continuous slines or cleats, and even the surfaces of deposition appear to be in a great degree obliterated. Its texture is porous. It is in very many, if not in all speci- mens, strongly charged with iron pyrites, which, by exposure to the air, efflorescing into sulphate of iron, gives the appearance of friability to the material, and by this means distinguishing it clearly from anthracite. Two samples of this combustible were tried for the purpose of ascer- taining the amount of earthy matter, volatile matter, and fixed carbon. The first gave of per cent. Volatile matter, 11 16 Carbon, 77.86 Earthy matter, 10.98 100. The second, which appeared to be rather more highly charged with py- rites than the other, gave, by the mean of four separate incinerations, of per cent. Earthy matter, only Fixed Carbon, 2 43 82.75 Volatile matter, * 14.82 100. The distillation of this fuel by the immediate application of a red heat, produces a gas which burns with a steady clear flame, of a yellowish white color, accompanied by a little smoke, which, however, nearly or quite dis- appears when the access of air is free and abundant. The distillation produces no enlargement of volume or adhesiveness of the particles of carbonaceous matter, as in certain serai- bituminous or " transition" coals, such as that found on Stony Creek, iu Dauphin county, Pennsylvania. Iu regard to the applicability of the term " natural coke" to this sub- stance, Prof. J. remarked, that understanding this term as indicating a change of texture from that of the bituminous coal of the same district, a partial discharge of the volatile ingredients of the same coal, and as a 32 224 [December, 1842. necessary consequence, a relative augmentation of the earthy material as well as of the fixed carbon, he saw no impropriety in its use, but, on tlie contrary, a peculiar propriety, inasmuch as neither of the other terms in general use to designate mineral fuel is applicable to this variety. He re- ferred to the geological report of the State of Virginia, in which an analysis of this substance is given, exhibiting its composition as follows, viz : Carbon, 80.30 Volatile matter, 9.98 Ash, 9.72 BUSINESS BY SPECIAL RESOLUTION.

Browne, Esq., on the subject of the supposed human foot prints found near St. Louis, in the Carboniferous Limestone, made a Eeport as follows : That they do not consider that the ingenious arguments of the author can tend in the least to invalidate the reason- ings of Dr. Owen in favor of the artificial nature of the foot marks. The evidence furnished by the paper and accompanying drawing of Dr. Owen, of which the com- munication before the Committee is a criticism, appears sufficient to place this question at rest for ever. That these impressions are not genuine imprints of the human feet, but rude imitations, is obvious upon a slight anatomical consideration of them. Both the form and attitudes of the toes are entirely at variance with nature, and are such as to suggest that the sculptor exercised but a slight familiarity with the structure and capacities of motion of the parts. A mere inspection will satisfy all anatomists upon this point. The geological proofs against their having been formed whilst the limestone was yet in a plastic state are no less decisive, since the facts stated by Dr. Owen go distinctly to show that the slab containing these foot prints is a por- tion of the carboniferous limestone formation of the Mis- sissippi Valley, the Oceanic origin of each layer of which every geologist is prepared to demonstrate. Formed in the bed of an extended sea, and buried previous to its upheaval under an enormous accumulation of other deposits, it is impossible to conceive how human footsteps could gain access to the unconsolidated rock, even if the human race had existence at the time. That the race of man is of incalculably later origin than the rock containing 226 [December, 1842. these representations of feet, is, however, a fact thoroughly established in geology. Setting aside, then, the possibility of referring the origin of these foot prints to the period of the formation of the rock, there is quite as little warrant for assigning it to any later period posterior to the upheaval and denudation of the stratum, for there are no facts connected with this, or any other of our ancient secondary rocks, which indicate that they retained their plastic condition after they were drained, to so late a date as ihe human epoch. Guided by these and other considerations of similar purport, your Committee express their conviction, that the arguments detailed in the paper submitted to them do not at all weaken the published proofs of the artificial nature of the supposed foot prints. On motion of Dr. Goddard, the communication of Mr. Browne, referred to in the above report, was ordered to be placed on file. STATED MEETING, December 20, 1842. Vice President Morton in the Chair.

MEETING FOR BUSINESS, AND ANNUAL MEETING. December 27, 1842. Yice President Morton in the Chair. The Annual Reports of the Librarian, of the Treasurer, and of the Publication Committee havinar been read and adopted, the following Report was presented on behalf of the Botanical Committee and adopted, and ordered to be published in the Procedings. The Botanical Committee having, during the present year, completed the arrangement of the extensive and valuable collection of Plants, pre- sented in 1839 hy Dr. F. Menke, of Pyrmont, Germany, beg leave to make the following statement, forming the principal portion of their Re- port, due at this season. The apparent neglect and delay in the arrangement of this collection on the part of the Committee, may be accounted for by the fact, that at the period of its presentation, preparations were in progress for the erection of the new Hall, and that after the removal of the Museum to the latter, a large portion of the time and attention of the Committee was required, in common with the other members of the Academy, for the disposal and ar- rangement of its collections in the other departments. During this period the plants had not been removed from the boxes in which they had been originally sent by Dr. Menk<5. On examination they were found to be very carefully and closely packed, and to have sustained no injury from dampness, and but comparatively few specimens to have been destroyed by insects. The whole collection had been arranged after the Linuean or artificial system ; the plants distributed into fasciculi and labelled accordingly. About two-thirds were well selected and character- istic specimens, in good paper, with labels containing the name with the authority for it, the synonyme, the locality, date of collection, and frequently the name of a donor. The remainder were enclosed in coarse brown paper, without order or arrangement, and although in most cases properly labelled ; in many close comparison and study were necessary, in order to determine even the generic character. The localities were chiefly Pyrmont, Bruns- wick, Bremen, Arolsen, Monspelier, and Gottingen. From the celebrated botanical garden in the vicinity of this latter, very many species had been derived. Specimens were occasionally met with from France, the West Indies, Hungary, &c. The greater part of this collection had been made between the years 1810 and 1815. Among the names of donors were many distinguished in Botanical Science, as Thunberg, Sprengel, Bernhardi, Prof. Treviranus, Prof. Mertens, Rasmer Goehnat, Lehtnann, Salzmann, Rohde, Weudland, Meyer, Shrceder, Ehrtnberg, Schmidt, &c. By a reference to the new catalogue, it will be seen that a large propor- tion of the genera (and most probably of the species) contained in this • December, 1842.] 229 collection were already possessed by the Academy. On this account, therefore, and as the number of cultivated specimens was large, the Com- mittee deemed it unadvisable to incorporate it with the Herbarium of the Academy, but concluded upon keeping it entirely distinct, adopting, how- ever, a similar plan of arrangement as in the Herbarium of the Academy, viz., combining, as far as possible, the Linnean or Artificial with the Na- tural System. To accomplish this duty occupied the time and attention of the Commit- tee for several months. The best and most characteristic specimens were selected, transferred to paper of uniform size and color, with the generic name attached to the left hand upper corner of the sheet; the genera being arranged in their appropriate natural orders, commencing with those latter which contained the largest proportion of genera belonging to the first Linnean class, and' so on proceeding to the last — this being the plan of the Herbarium of the Academy alluded to above. As thus completed, the collection comprises 1298 genera, including up- wards of 7000 species. Of these, 5623 species are Phoenogamous, includ- ed in about 130 natural orders; and 1272 species are Cryptogamous. Of the latter, the Ferns embrace 132 species; Equisetum, LycopodiumJ and the Marsileaceae, 29 species; Hepaticae 65 species; Musci 309 species; Algaj 122 species; Lichenes 152 species; and Fungi 445 species. To these are to be added 18 species of Corallia, and a number of plants to which neither the generic nor specific name was attached. The whole has been distributed into thirty-6even folio volumes of large size, occupying an entire case six and a half feet high, four feet wide, and tweuty-one inches in depth. The duplicates are very numerous, and will answer for exchanges. The new catalogue, alluded to above, has been. found necessary, on ac- count of there now being two separate collections, the previous catalogue referring but to one. It is furnished with a double column of reference, so that a genus contained in both collections can be very readily found. A number of donations, some of which are of much value, have been received by the Academy during the year. These have been already noticed in the published Proceedings at the time of presentation. The chief donors have been our fellow members £• A. Browne, Esq., and Mr. R. C. Taylor; Dr. George Engelmann, of St. Louis, Missouri, and Prof. Short, of Louisville, Kentucky. The duty of incorporating these donations with the Herbarium has been necessarily deferred until next year. On behalf of the Committee, Wm, S. Zantzinger, Robert Bridges, Gavin Watson. Uall of the Academy, December 27, 1842. NEW BUSINESS.

A letter was read from Redmond Conyngnam, Esq., dated Oak Hill, near Paradise, Pennsylvania, January 14, 1S43, 236 [January, 1843. returning his acknowledgements to the Academy for his elec- tion as a Correspondent. The Chairman read a letter from Mr. W. Byrd Powell, dated Little Rock, Arkansas, December 3, 1842, soliciting exchanges, and desiring information on subjects connected with Natural History. Also a letter from Professor Locke, of Cincinnati, contain- ing further observations on the subject of the fossil Crypto- lithus tesselatus, described by him in a former communi- cation to the Academy, and published in its Proceedings.* In this letter he states, that since the publication of his paper, he has had an oppor- tunity of examining a large number of specimens, which have enabled him to correct his description in several par- ticulars, viz : " The appear- ance that the shield covered a part of the articulations was accidental ; these articula- tions are six in number, and uncovered by the shield, ex- cepting the outer portion of the anteriorcostal arches, (see figure ) The tail in the most perfect specimen consists also of six articulations, each sub- divided by an inferior joint or depression, giving the ap- pearance of twelve articulations. The middle lobe of the tail is itself trilobate, appearing like the whole body of a small trilobate entire." * See Proceedings for July, 1842, pp. 196, 197. yj>/ January, 1843.J At the suggestion of the Chairman, the communication from Dr. Ravenel, read at a late meeting of the Academy, describ- ing a new species of Pecten, was referred to a Committee. Mr. Phillips, Dr. Morton, and Mr. Conrad were appointed as the Committee. MEETING FOR BUSINESS, January 31, 1S43. Vice President Morton in the Chair. After the Reports of several Committees, and that of the Corresponding Secretary had been read, the following An- nual Report was presented by the Recording Secretary. REPORT. In presenting his Report of the operations of the Society during the past year, the Recording Secretary embraces the opportunity of congratulating the members upon the present condition of the Institution, and the flatter- ing prospect which it has of prosperity for the future. The state of its finances, as appears from the report of the Treasurer, and, to use his words, " is superior to that of any period since its organi- zation." This satisfactory state of things has been occasioned principally by the receipt, in February last, of the sum of $6000, being the balance of the second subscription of the late William Maclure. To his brother and executor, Mr. Alexander Maclure, is the Society under great obligations, for the persevering efforts which were made by him to accomplish this object, and also for the interest which he manifested in the general wel- fare of our Institution. The Academy has been thereby enabled to liqui- date several urgent claims, and greatly to reduce the debt incurred in the purchase of the ground on which the present building is erected. In addition to this, its funds have been considerably augmented during the last few months by the final and successful settlement of a long pend- ing suit for a claim of upwards of $5000 against the heirs of an unsettled estate. This was a mortgage transferred to the Academy many years since, by the late Wm. Maclure. In consequence of many difficulties and vexatious delays thrown in the way of settlement of this matter, the Aca- demy had hitherto been unable to make this fund in any way available. By a compromise made with the heirs, fourteen per cent, of the 23S [January, 1S43. whole amount has heen deducted for their use; the balance, amounting to $4549, is in Pennsylvania five per cent, stock, to which is to be added $430 interest, paid in par funds, and §113 in six per cent. Pennsylvania stock, also as interest; the latter being redeemable by the State in August next. In accordance with the desire of Mr. Alexander Maclure, the first mentioned sum will not be appropriated at present by the Academy, but retained until some improvement in the stock occurs, which, it is hoped, will be at no distant date. At all events, the Society has the positive assurance of Mr. Maclure that no loss shall be sustained, and that both principal and interest shall be eventually realised. For the final adjustment of this affair, the Academy is under great obli- gations to this gentleman, to the Counsel of the Academy, and to several other members. The Museum of the Academy has been augmented by large and valuable additions to all its departments during last year. The details of these presentations, with the names of the donors, have been already given in the published Proceedings of the Academy during the year, and need not, therefore, be repeated here. But a brief mention of the names of those who have contributed most largely in each department is considered due to them, and will not be unacceptable to the Society. Cairo, Egypt, J. Hamilton Couper, Esq., of Georgia, Mr. Joseph Brano, of Philadelphia, and minor donations by Drs. Chaloner, Watson, Carson and Blanding, and by Prof. W. B. Rogers, of Virginia. In the Ornithological department the presentations have been large and valuable, and made chiefly by Prof. Holbrook, of South Carolina, Mr. Charles Twigg, of New Harmony, Indiana, Mr. J. W. Rulon, and also by a club of members. Also by Mr. .1. G. Bell, of New York, by the President of the Society, Mr. Wm. Hembel, and by Mr. George W. Carpenter, Dr. William Blanding, and Mrs. William Fnrness, of this city. To the Cabinet of Shells important additions have been made by Dr. Paul B. Goddard, Dr. Benjamin B. Brown, of St. Louis, Missouri, Mr. .1. Hamilton Couper, Dr. Wm. Walker, of Nashville, Tennessee, and Dr. J. C. Jay, of New York. Also by Mrs. Lucy W. Say, Mr. P. H. Nicklin, Mr. Haldeman, Mr. Phillips, Mr. Conrad, Mr. Cassin, &c. The Botanical department has been indebted for well preserved and in- teresting donations of plants to Peter A. Browne, Esq., Mr. Richard C. Taylor, the Rev. J. P. Durbin, Prof. Short, of Louisville, Kentucky, Dr. George Engleman, of St. Louis, Missouri, J. Frampton Watson, Esq.; and also to Drs. Carson, Godon, and others, A portion of the Herbarium containing the natural family Composite has been carefully examined by Dr. Asa Gray, of New York, in whose hands it had been placed, at his own request, for this purpose, and has been considerably improved, and some additions made to it by him. A very large collection of plants presented in the year 1839, by Dr. January, 1S43.] 239 Menke, of Pyrmont, Germany, has been at length examined and arranged by the Botanical Committee, 'whoso Report states that, as arranged, it con- tains not less than 7000 species in excellent condition. On account of its size and value they have decided upon keeping it in a separate case from those containing the Academy's Herbarium, and to designate it the " Menke Collection." Of Minerals, the donations have been chiefly from the following mem- bers and others. P. A. Browne, J. Randolph Clay, George R. Gliddon, Wm, S. Vaux, J. A. Clay, Esqs., Dr. Wm. T. Craige, &c. In the Entomological department we have had but a single donation to record in the past year — that made by Mr. Charles Twigg, of New Harmony, Indiana, of insects from that region. The Secretary, however, has the satisfaction to state, that it is the determination of several members to exert themselves during the coming season, personally, and throuo-h friends in the United States, in making collections of American Insects for the Academy. He would respectfully suggest that the aid of Foreign Correspondents be also solicited for this purpose. To the Museum there has also been added a number of fine Quadrupeds, Reptiles, Fishes, Skeletons of Animals and Crania, by members and cor- respondents. The donations made by the different contributors mentioned, are upwards of eighty in number. It would be difficult to form a just estimate of the number of specimens embraced by them ; it cannot, however, fall short of from four to five hundred. Taken collectively, they form a mass of great value to the lover of Natural Science, and for which the Academy has every reason to return its thanks to those persons who have thus testified their desire to promote the interests of the Institution. The Library has received an equal share of consideration. Many of the works presented last year are of great value, and the additions are equal in number to those of former years. The entire number of volumes, pamphlets, works published in parts, &c, added to the Library in 1842, has been one hundred and thirty-two; and of these, according to the report of the Librarian, sixty-nine are new works. For some of these the Aca- demy exchanges its own publications with other Institutions and indivi- duals. A large proportion of them, however, have been voluntary contri- butions from authors, members, and correspondents. A new set of cases, occupying the whole extent of the South Flying Gallery, has been recently completed, which adds much to the appearance of the Hall. One-half of these cases has been appropriated to the valuable collection of crania belonging to Dr. Morton, and the remainder to the ac- commodation of a very extensive series of volumes containing the debates and proceedings of the different legislative bodies of France during the period of the Revolution. Its great size, in fact, (upwards of 1600 volumes,) has hitherto prevented its introduction into the Hall, lest it should encroach too much on the space in the Library allotted to works of a strictly scien- tific character. As a full record of the events of that epoch of history it is highly valuable, and is believed to be possessed by no other Institution 2-40 [January, 1843. in this country. There are, besides, duplicates of many of these volumes, which the Academy could, without doubt, exchange for scientific works, or dispose of in some other way. The meetings of the Society have been held with great regularity during the year, at the stated periods, without a single exception, and have been characterised by ample evidences of zeal and interest in the cause of science. Many valuable original papers have been presented, most of which have been published either in the Journal of the Academy, or in its Proceedings, and have contributed still further to advance the high character of our Institution. The Second Part of the 8th Volume of the Journal was issued about the middle of the year, and besides the papers referred to, contains many well executed and faithful illustrations of the objects which they describe. The Proceedings have been published at intervals of from one to three months. This plan of publication was commenced early in the year 1841, and has been adhered to ever since with advantage to the members and corres- pondents— affording them a medium for acquainting the scientific public with their discoveries and observations without delay. Several prominent members have had in view for some time past the reduction of the annual contribution to one-half its present amount, and have only been prevented from bringing the subject before the Society, for its action, from a conviction that its best interests would be consulted by deferring it until something more definite and certain was known re- specting the amount of reduction which would be effected in the remaining debt of the Academy during the present year. An effort will then be made at the earliest practicable period to accomplish this object, which, it is believed, is desired by a large majority of the members. From the statement thus given of the operations of this Society during the past year, it is hoped that the assertion made at the beginning of this report, that its present condition is flattering, will not be considered as having been premature or unfounded. With no other debt remaining, except the one just referred to — and that in the way of reduction at an early period, and to such an extent as, after its accomplishment, to admit of the Society's appropriating annually a considerable portion of its income to the scientific purposes of the Insti- tution— with a list of nearly one hundred and fifty contributing and resi- dent members, and of three hundred and seventy domestic and foreign cor- respondents, mostly zealous in aiding the Institution, and in promoting the objects for which it was founded, it is not hazarding too much in express- ing the belief that by a steady continuance of these efforts, and a prudent management of its financial concerns, its prosperity must henceforth be permanent. Twenty-five years only have elapsed since this Institution was incor- porated. It is therefore still in its youth. In that time it has advanced from comparative unimportance, to a consequence and standing which the most sanguine of its founders could scarcely have anticipated. To the industry, talent, zeal and liberality of many of its members, is this to be January, 1843.] 241 attributed, but chiefly to the aid derived from its early friend and patron the late Wm. Maclure. For conducting it through many difficulties during the early part of this period ; for furnishing the principal portion of the means for erecting the edifice in which we are now met; and for the abundant evidences of his generosity in every direction around us in this Hall, do we owe him our grateful acknowledgements. A distinguished member of this Society, who is himself one of its warmest and most active friends, and who has contributed in no small degree to its advancement, has already done ample justice to the memory of Mr. Maclure for these acts.* But there still re- mains with us the obligation, which is of no light character, to use every suitable endeavor to place this Institution in that elevated position which, in making it the special object of such munificence, it was the design of Mr. Maclure it should hold. All which is respectfully submitted, by Wm. S. Zantzinger, Recording Secretary. Hall of the Academy, January, 1843. An alteration of Article VII, Chapter 3, of the By-Laws, proposed at a former meeting, was then unanimously adopted. The By-Law, as amended, now requires of ;' Correspondents residing in the United States/' elected after this date, "a Diploma fee of five dollars." The Report of the Auditors on the Treasurer's account for 1842, was then read and accepted ; and the Society, after having transacted some other business, proceeded to an elec- tion for Standing Committees for the year 1843.

A communication from the American Philosophical So- ciety, acknowledging the receipt of the last No. of the Aca- demy's Proceedings. A Circular from the Medical Department of the National Institute at Washington, soliciting communications, and pro- posing inquiries on certain medical subjects. And a letter from Prof. Locke, dated Medical College, Cincinnati, Ohio, January 23, 1843, describing some extra- ordinary and beautiful forms of Sulphate of Lime, or fibrous Gypsum, found in the Mammoth Cave, Kentucky. For these, as being a peculiar variety of this mineral, he suggests the new name of "Oulophyllites." Prof. Johnson read an extract from a letter from Prof. F. W. Johnston, of Durham, England, announcing the cha- racters of a new species of sugar resembling mannite in ap- pearance, but in the crystalline state having the constitution of grape sugar, viz.: Carbon 24, Hydrogen 28, and Oxygen 2S; but losing by heat seven atoms of water, becoming Car- bon 24, Hydrogen 24, Oxygen 24. This sugar drops from certain species of Eucalyptus which abound in Van Dieman's Land and in New Holland. It is not so sweet as grape sugar, and is not likely, therefore, to meet with any extensive economical application. Theo- retically, however, it is very interesting.

WRITTEN COMMUNICATIONS. A letter was read from Major J. D. Graham, accompany- ing his donation above mentioned. VERBAL COMMUNICATIONS. Professor Johnson exhibited some samples of sheathing copper from the bottoms of vessels, which showed the effects of corrosion and attrition after it had been in use for a very limited period, and alluded to the great deterioration, of late years, in the quality of the commercial article, both in this country and abroad. 246 [February, 1843. As it was highly important to the interests of Commerce and of the Navy that some test should be had which might be conveniently put in use for ascertaining the degree of purity of sheathing copper; and as che- mical tests were not always at hand, or readily applied by inexperienced persons, Prof. Johnson had invented an apparatus, of simple construction and easy management, called a test vice, which he exhibited and explained, by means of which the degree of tenacity of portions of sheathing copper could be readily ascertained. Strips of copper from different sources, about an inch in width, were 'hen subjected to the test, and their comparative value determined by the number of bends which they would bear until fracture was produced. Prof. Johnson also exhibited two specimens of Cannel Coal, one termed by him slaty Cannel, from Kentucky, and the other from Missouri, called floating Cannel, from the circumstance of its floating on water' which fluid it afterwards absorbs, and then sinks. Prof. Johnson also gave the results of his analysis of these coals, which accorded in mos1 respects with that of the Cannel Coal of Scotland, as obtained by Mr. Richardson. MEETING FOR BUSINESS.

Professor Rogers remarked, in reference to the fossil specimen presented this evening by his brother, that no recent contribution to our Palseontology was more inter- esting at this time than the discovery, by the latter, of this familiar European species, in a particular division of the New Red Sandstone of Virginia. Being an abundant and characteristic shell of the Upper New Red Sandstone of Europe, its occurrence in this country is regarded by Prof. W. B. Rogers as affording the first decisive indication of the precise date or equivalency of the extensive American formation already referred by Prof. Hitchcock, by himself and other Geologists, to the general Poikilitic or New Red Sandstone period. March, 1843.] 251 • STATED MEETING, March 14, 1843. Yice President Morton in the Chair. WRITTEN COMMUNICATIONS. Mr. Phillips read a communication -addressed to the Academy, from Mr. John G. Anthony, of Cincinnati, Ohio, dated February 19, 1843, of which the following is a portion. " By the published transactions of the American Philo- sophical Society for 16th December last, I perceive that Mr. Lea has described twelve species of Melania from Alabama and Tennessee. One of these, under the name of ' M. excisa,' he proposes to erect into a new genus, under the name of 'Schizostoma,' on account of the deep slit in the lip. Having possessed specimens from the same localities for some time past, embracing, as I believe, seven or eight species of this proposed genus, I have referred them to Swainson's genus, 'Melatoma,' founded, as he states, ' upon a Shell sent him many years ago by his old friend Professor Eafinesque, and which, he says, has the general form of Pleurotoma melafusus, with a well defined sinus or cleft near the top of the outer lip.' I have mentioned this with a view to call the attention of the members to it, and to have the question of nomenclature settled correctly. I have, within two months past, received one species of this genus from Dr. Mighels, of Portland, Maine, under the name of 'Apella scissura.' " The communication was accompanied by a second and corrected edition of his Catalogue of the Terrestrial and Fluviatile Shells of Ohio. Mr. Cassin read a paper intended for publication, and entitled "A Description of several new and rare Birds from the Kocky Mountains and California, by William Gambel:" 252 [March, 1843. which was referred to Messrs. Cassin, Phillips, and Halde- man, as a Committee. The Corresponding Secretary read letters from M. Flourens, Perpetual Secretary of the Eoyal Academy of Sciences of France, dated Paris, January 19, 1843, and from Prof. Berzelius, Perpetual Secretary of the Eoyal Academy of Sciences at Stockholm, dated November 7, 1842, severally acknowledging the receipt of copies of the Pro- ceedings, and other publications of the Academy. Also a letter from Mr. B. F. French, of New Orleans, acknowledging the receipt of his notice of election as a Correspondent. VERBAL COMMUNICATIONS. Dr. Cogswell, Secretary and Librarian of the Northern Academy of Arts and Sciences at Hanover, New Hamp- shire, then briefly addressed the Society in reference to the origin and design of that Institution, and on its behalf solicited several volumes of the Journal of the Academy, which it was desirous of possessing in order to complete its series of the same. The Chairman announced that Mr. John James Audubon and Mr. Edward Harris, accompanied by an artist, left this city yesterday morning on their route to St. Louis, and thence to the sources of the Yellow Stone Eiver and the Eocky Mountains. The object of this expedition is the discovery of new species of Birds and Quadrupeds for the works of Mr. Audubon, and especially for his Mammalogy of North America, now in course of publication. The expedition is expected to return in October, and promises important additions to every department of natural science. The Chairman also called the attention of the Society to the first number of Mr. Audubon's "Quadrupeds," which is placed in the Hall for inspection, and for the subscription of such members and others as may desire to possess this truly splendid and invaluable work.

Rogers drew the attention of the Society to the stratigraphical features of the environs of St. Petersburg, as represented in the maps and sections appended to the volume of "Publications of the Imperial Russian Society," just laid upon the table. He pointed out, in particular, the perfect identity in the form of the Russian anticlinal flexures and those of the Appalachian chain of the 'United States; the resemblance con- sisting in the want of a symmetrical curvature in the arches, and an inequality in the steepness of the dips on the opposite sides of the axes. Alluding to the structural laws first developed by his brother and himself from a study of the Appalachian chain, and conceived by them to characterize regions of anticlinal axes generally, he proceeded to show that upon the theory of the origin of these flexures, the same style of curvature should be met with in all countries, as a necessary consequence of the universality of those laws. The exhibition, therefore, of an anticlinal arch, having the normal form, in the banks of the Pulkowka in Russia, goes to conGrm the generalizations of these authors. Instances of the same characteristic feature are to met with abundantly, however, in the sections which geologists present of the stratification in many other districts of Europe.

April 25, 1843. Vice President Morton in the Chair. The Monthly Report of the Corresponding Secretary was read and adopted. / The Committee, consisting of Prof. Johnson, Mr. Halde- man, and Mr. Peale, to whom was referred, in November, 1842, a communication from Peter A. Browne, Esq., accom- panying some specimens of an earthy matter from Lancaster county, Pennsylvania, supposed to be identical with Terra di Sienna, made a report, which was adopted. The report stated that after a careful investigation of the subject, and comparisons in several modes with the genuine article, the Committee had formed the following conclusions: "That the earth in question is a hydrated silicate of Alu- mina tinged with variable proportions of peroxide of iron; 8.17 grs. of one of the best samples having been calcined at redness for twenty minutes in a platinum capsule, left 6.74 grs. of dark brown fragments, showing a loss of 17.5 per cent, of water" — "and that for certain minor purposes in the arts, this coloring matter may be highly useful, but as a general substitute for Terra di Sienna, it cannot be expected to gain the approbation of artists." The Committee, consisting of Mr. Cassin, Mr. Haldeman, and Mr. Phillips, to whom was referred Mr. William Gambel's* paper, entitled " Descriptions of some new and rave Birds of the Rocky Mountains and California," reported in favor of its publication, with the exception of the generic and specific characters of the Eudromus variegatus of that paper, which they deem it expedient .to defer until the receipt of the specimen. * This gentleman has just completed the tour of the Rocky Mountains aud California, at the instance of Mr. Kuttall, to whom this paper was originally addressed, and by him referred to the Academy for Publication.

Male, varied with black and white ; back transversely banded with black and white; upper part of the head black with linear white spots ; hind head with a broad red stripe ; sides of the head and neck black, with a wide stripe running from the base of the bill about the length of the head, also white stripes running from the eyes and uniting on the back of the neck, which is black. Rump and two middle tail- feathers black. Wing-feathers on their outer and inner webs, with six or seven bands of white spots ; all the wing coverts also with white spots ; tips of some of the tertiaries light brown. Beneath white, with a slight tinge of yellow ; sides and vent with dark brown spots ; lower tail coverts and tail-feathers, except the two middle ones, white, with irregular bands or spots of dark brown ; throat and breast white ; second quill shorter than the seventh ; third, fourth, and fifth nearly equal. Two white tufts of hair-like feathers at the base of the upper mandible. Irides red. Length seven inches. This pretty species I shot in a willow thicket near the Pueblo de los Angelos, Upper California, December 10th. It was actively en- gaged pecking into one of the trees ; from time to time uttering a singular note, unlike any I have heard from a woodpecker. It is, perhaps, a common species in the summer time. Parus* montanus. Male. — Head, upper part of the back, throat, and upper part of the breast pure black; two white stripes commence on the front and extend over the head about the length of it, leaving a black band in the centre and a stripe running over each eye to the nape ; cheeks and shoulders white. Wings and tail brownish 'gray; beneath whitish ; tinged with brown on the sides and vent. Legs bluish. Length a little over five inches. Tail two and a half inches. This new and distinct species we first observed about a-day's jour- ney from Santa Fe, in New Mexico, and from thence in all the ranges of the Rocky Mountains nearly to California. Its manners and notes are very much like those of the common Chickadee, but the lat- ter are more weak and varied. It keeps also much in low bushes, where from morning to night, with untiring patience and activity, it may be seen hopping from bush to bush, searching them minutely for small insects. It also frequently descends to the ground to pick up small seeds ; when thus occupied it occasionally stops, looks around and utters a slender te de de de, then altering to de de dait, flies off to some other bush. On the Rio Colorado it keeps much in the cot- ton wood trees which grow along its banks, and its notes, which be- came familiar, were almost the only ones heard in the winter, when 260 [April, 1843. we were there, to cheer our course. This species is sometimes seen in company with the P. minutus, Town., and Regulus calendula, which at this time are roving in large and busy flocks along the small streams. It is probably found also in the mountains of California. Fringilla Blandingiana.\ Male. — Above olive green tinged with cinereous and brown. Crown i-ufous red ; front, line over the eye, ears, and breast cinereous ; throat pure white ; a white line also running from the base of the lower mandible to the neck, below wliich is a line of blackish tipped with cinereous. Sides brownish ; belly and veDt white ; wings and tail brown ; wing coverts, margins of the primaries and secondaries and tail feathers, especially near the base, bright yellowish green ; tail be- neath pale green. Length six and a quarter inches. Feet and legs stout, brown ; tarsus and middle toe, with the nail, seven-eighths of an inch in length ; hind toe nail longer than the toe ; bill above dark brown, beneath paler. Of this new and singujarly marked species I procured a single specimen only, in September, on the bank of a small stream in the Eocky Mountains, about half way between New Mexico and the Col- orado of the west. It kept in low bushes in company with the F. guttata, Nutt., and F. graminea, occasionally uttering a single chip. The throat and breast of this species very much resemble those of the F. Pennsylvanica. Lophortyx* Gambelii, Nutt. Cinereous-brown above ; head bright rufous ; crest of six black feathers one and three-fourths inches long, wide at the tips and curv- ing forwards ; throat black, banded by a line of white ; front of long grayish and black bristly feathers, with a baud of white across them near their tips, which extends over the eye to the back of the head; feathers of the neck and upper part of the back small, cinereous, each with a central streak of dark rufous; upper part of the breast and shoulders cinereous; lower part of the breast cream colored; middle of the belly black; flanks dark rufous ; each feather with a large lan- ceolate central spot of pure white ; tertiaries edged on their upper margins with yellowish white; tail rounded, cinereous blue; under coverts with dark brown spots. Length a little over ten inches. Wings four and a half; fourth quill longest: second and seventh equal. Bill black. Feet and legs dull bluish. Tarsus one and a quarter inches. Tail four and a half. We met with small flocks of this handsome species some distance west of California, in the month of November, inhabiting the most -j- In honour of Wm. Blanding, M.D., of Philadelphia. April, 1843.] 261 barren brushy plains, covered with a species of Chenopodium. Here, where a person would suppose it to be impossible for any animal to subsist, they were seen running about in small flocks of five or six, occasionally uttering a low guttural call of recognition, sometimes of several notes, very different from that of the common species. When flying they utter a loud sharp whistle, and conspicuously display the long crest. Lanius elegans. White winged Shrike, Swains. This species, of which but a single specimen is knowntto Ornitholo- gists, I found abundant in California, in the brushy plains, and some- times in the hedges near the towns; it flies close to and frequently alights on the ground and on low weeds ; when flying, its white banded wings can be seen very distinctly; in the adults the breast is pure white ; in the young blended with dark brown, like our common species, except the throat and vent, which are white; some- times, when disturbed, it has a harsh crying note like a jay, pay pay pay. Sciurus tenuirostris? Swains. Synopsis Birds of Mexico? Above olive brown ; beneath tawny yellow ; sides of the throat, with the breast and sides, marked with irregular streaks and spots of dark brown; a yellowish white line over the eye; throat, belly, and vent without spots. AVings and tail blackish brown, the feathers margined with yellowish white; two outer tail-feathers almost wholly white ; the second merely tipped with the same. Length six inches ; tarsus seven-eighths of an inch; hind toe nail as long as the toe. Bill slender ; half an inch in length. We met with this species only on the Rio Colorado ; at that time (October) keeping in small flocks along the bank of the river, some- times wading in the water to pick up whatever they might find in the mud, with which their bills were covered. When sitting they jerked their tails in the manner of the S. Noveboracensis, which they somewhat resemble ; they also uttered, when flying, a few slender notes. Swainson questions the S. tenuirostris being found on the table land. This species, I should think, was not, from its habits, although I saw a few specimens among some sage bushes (Artemisia) near the river. Ptilogonys Townsendii, And., Xutt. This rare and singular bird, of which but a single specimen has been obtained in Oregon, I first met with, in .October, on the banks of a small, rocky creek, in the Rocky mountains, between the Rio Colo- rado and California. Here, in the depth of solitude, it was flying along the stream, alighting on the rocks, and jerking its tail in a lively 262 [April, 1843. manner, feeding solely on buffalo berries (Shepherdia) which grew plentifully along its banks, and with which its stomach was crammed. We afterwards found it on one of the highest and most desolate moun- tains, near a small pool of water, to which, towards evening, various kinds of birds came to drink, and amoung them two individuals of this species, which I killed ; ' but these, like the specimen procured by Mr. Townsend, were females, as are all the specimens I have obtained. It appeared to have somewhat the manner of a fly-catcher, and I never heard it utter«a note. Turdus nanus, Aud., Nutt. This small and, I think, perfectly distinct species, we saw frequently in the Rocky mountains, frequenting low solitary places, and keeping much on the ground. In California, and also near the Pueblo de los Angelos, in January, I have seen several specimens in the willow hedges and brushy places in company with the sparrows. Though it resembles, in general appearance, the T. solitarius, it may easily be distinguished by its smaller size, never exceeding six inches in length. Fringilla Gambelii, Nutt., Man. of Ornith. « This species, procured in Oregon by my friend Mr. Townsend, was very common on the road from near New Mexico to California, where it is also seen in almost every hedge in company with F. leucophrys, to which it is closely allied, if not the same species. ERYTHRospizA/rcwtaZi's, Bonap. In California this species is extremely abundant at the time we were there (January), keeping in small flocks in the neighborhood of the towns, and frequently in the gardens in company with various species of sparrows. It has much the habit of E. purpurea, but is more fami- liar. In Santa Fe, in New Mexico, it builds its nest under the portals of the houses in the public square, and alights familiarly about the doors ; in July they had fledged young. They also appeared here to have a partiality for meat, which is frequently hung up in the sheds, eating it greedily whenever they had an opportunity. In California, also, I have observed them examining the sheds and portals, perhaps for places suitable for building their nests. DEFERRED BUSINESS. The Society then proceeded to the consideration of two Eesolutions offered at previous meetings, to alter Article I., Chapter III., of the By-Laws, reducing the amount of the April, 1843.] 263 initiation fee from $10 to $5; and Article 3d of same Chap- ter, reducing the amount required to constitute a Life Mem- bership from §80 to $50 — both of which were adopted. NEW BUSINESS. Dr. Morton stated that he had deposited in the Academy a large number of valuable letters and papers which had been placed in his hands by General Parker, Administrator to the Estate of the late Zaccheus Collins, embracing the Botanical Correspondence of the latter with Muhlenberg, Baldwin, Elliott, Bigelow, Schweinitz, Nuttall, and other American Naturalists; whereupon a resolution was adopted instructing the Botanical Committee to collate and arrange these manuscripts and have them bound and placed in the Library of the Academy. .

Mr. Haldeman exhibited a number of relics taken from the grave of an Indian, among which were some portions of human bone, and several small metallic cones enclosing hu- man hair. All which were in contact with the metal, or in its immediate vicinity, were in a high state of preservation. Mr. Haldeman inquired whether this preservation might not be accounted for on the principle of galvanic action. Dr. Bridges believed that the presence of the copper was alone sufficient to account for it ; the bone particularly would be found, on close inspection, to be hardest and best pre- served in those parts of it most deeply coloured by the copper, 270 [May, 1845.

VERBAL COMMUNICATIONS. Dr. Owen accompanied his presentation with the following remarks, explanatory of the geological position of these fossi^ trees : They were discovered twelve miles from New Harmony, in excavating in a slaty clay in the bank of Big Creek, a tri- butary of the Wabash, about fifteen feet below the surface, and about the same distance above the bed of the stream. Since the first commencement of operations there have been found, as nearly as can be ascertained, from twenty to twenty-five stumps, though the whole superficial area of the excavation is only about 3000 feet. They were all standing erect, and nearly on the same general level. Dr. 0. had him- self excavated three ; the largest of these was about three May, 1843.] 271 feet in height and sixteen inches in diameter. All of them were provided with well preserved roots, ramifying in the substance of the surrounding argillaceous deposite. About one foot above the fossil trees is a layer of sand- stone, and a partially disintegrated seam of coal a few inches thick; fifteen feet below, and beneath the water in Big Creek, is a seam of coal supposed to be from three to four feet thick. Nodules of argillaceous iron ore are dissemi- nated in the surrounding slaty clay. No appearance of a dirt bed was discovered. The horizontal section of these trees exhibits no medullary rays nor annual growths ; but the structure of the bark is visible on the external part of most of the specimens, and part of it is generally converted into a dark carbonaceous substance. The scars, left from the falling off of the leaf- stalks, though small, are distinctly visible in some of the smaller specimens. From the diameter of these scars being longer horizontally than vertically, and the absence of pa- rallel flutings, these monocotyledonous fossil trees are consi- dered as belonging to the family of palms. With the exception of the fossil palm trees, found at Dixon fold, on the Bury and Bolton Railroad, in England, this ap- pears to be the only authentic instance of the occurrence of well preserved specimens of fossil palm trees in strata of the arboniferous epoch. 272 [May, 1S43.

Dr. Mortem, (upon resigning the chair to Dr. Goddard,) commu- nicated some interesting information respecting the Cicada septem- decim, or seventeen year locust, which, during a recent journey from Rahway to Haddonfield, in the State of New Jersey, he had observed in very great numbers. They made their appearance there three or four weeks since, and were chiefly to be found in the tract of country lying between the two places mentioned, not ex- ceeding fifty miles in extent. In one apple orchard the trees were literally loaded with them ; some trees Dr. M. supposed to contain not less than two thousand. The foliage or other vegetation, so far as his observatien extended, had as yet sustained no perceptible injury from them ; and naturalists were still undecided with re- June, 1843.] 277 gard to the kind or source of sustenance preferred by the insect during the time it remains above the surface. Dr. Morton referred to the minutes of a former year, 1834, when this insect had appeared in the city and its vicinity, for a re- cord of interesting information on the subject, which, at his request, was read by the Secretary. [The following extracts from the minutes alluded to have not been published at any previous period, and are presented at this time, chiefly with the view of calling the attention of members and others to the subject, and of inducing farther investigation. At the meeting of June 3d, 1834, Dr. Harlan stated that on the 25th of May last he had observed the Cicada septemdecim in such large numbers as to blacken a field of wheat in the vicinity of the city : they were also very numerous in some of the public squares- It was his belief that the insect increased somewhat in size while it remained ; and also, that nothing was known respecting its food. Upon dissection, mere rudiments of the organs of digestion were found. Mr. Rogers, on the contrary, stated that in 1817, the trees in the neighborhood of Baltimore had been stripped of their leaves by this insect. He also expressed some doubt as to their common origin, from the fact of their periodical return not being necessarily in the same year in different parts of the country, and that this was probably owing to geological causes. Dr. Keagy had seen them in 1815 in the Valley of the Missis- sippi ; in 1817 near Baltimore, and in 1832 in Westmoreland county, Pennsylvania ; Dr. R. Coates in 1818, in Burlington county, New Jersey; Mr. Gibbons in 1825, near Moorestown, New Jersey, and in 1827 in the eastern part of Virginia ; Mr. Johnson in 1831, near Rochester, New York; and Dr. Morton in 1817, in Westchester county, New York. Dr. Coates had seen a tree in Germantown nearly destroyed, in 1817, by the deposition of the ova of the insect. • Dr. Pickering stated that this Cicada had not yet been met with in the eastern part of New England, but that a rare species of Cicada had been found nearly resembling the C. septemdecim, and which might be easily confounded with it; the latter differed, how- ever, in the abdomen being all black: in the former, the rings of 278 [June, 1843. the abdomen have each a red border; they were usually found in rocky soil. At the subsequent meeting, Mr. Gibbons read an extract of a letter from his brother on the subject of the Cicada septemdecim, in which the writer stated that he had seen them feeding on the sweet gum, by pushing the proboscis into the bark ; when this organ was withdrawn a drop of fluid appeared at the aperture, which served for food to some ants. Dr. Mutter exhibited a dissection of the singing apparatus of the Cicada septemdecim, consisting of the diaphragm and an air cell and sounding board on each side, and a pair of muscles. The whole is distinct from the abdominal cavity. The proboscis was hollow, and intestines convoluted, without perceptible oesophagus or stomach. Mr. Lukens mentioned that with Mr. T. B. Peale he had seen the Cicada septemdecim feeding, by pushing the proboscis into the bark of trees, particularly young beech trees. At the meeting on the 1st July, Dr. McEuen (then Eecording Secretary) stated that the C. septemdecim had disappeared from some places in the vicinity of the city since the occurrence of a heavy rain ; he also exhibited the young branches of trees in which the ova of the insect had been deposited in punctures in longitu- dinal lines, many in one perforation. The young branches had been thereby for the most part destroyed. Dr. Buschenberger, at the meeting of July 8th, observed that in travelling from Baltimore to Frederick, Maryland, he had found the C septemdecim abundant at the two places mentioned, whilst none were seen in Montgomery county, between Baltimore and Washington.] After the above extracts had been read, Prof. Bogers made some remarks on the subject, chiefly confirmatory of the opinion ex- pressed by him in 1834, of the periodical return of the insect being influenced by geological causes. Dr. Goddard referred to the well known fact of the C. septem- decim being occasionally found in a living state at a great distance below the surface. When so discovered, its head is usually down- ward. According to the published statements of a recent observer, Mr. Ehrenberg, of Berlin, minute infusoria may be found at a great June, 1843.] 279 depth in the earth, and authorizing the conjecture that Dr. G-. offered, that these infusoria afforded sustenance to the insect during its long absence. He expressed his belief that no satisfactory rea- son had as yet been given for its reappearance at regular periods. As another fact, not probably known to the members generally, he mentioned that the yolk of eggs brought from the district of New Jersey at present visited by the insect, had lost, in a great measure, their yellow color. This had been observed in former years, and was supposed by the farmers to be caused by the fowls feeding on the insect. Mr. Gliddon stated that in Lycoming county, in this State, whence he had recently returned, the insect had been very nume. rous, but at the time of his visit had nearly disappeared. The sto. machs of some trout which he had caught there were found to be gorged with it. Mr. Cassin had been informed that the C. septemclecim was now very abundant in other counties of the State, particularly near Mauch Chunk. He also stated that the irregularity in the time of the appearance of the insect had been supposed to be owing to the overlapping of adjoining districts ; as an example of which Loudon <;ounty, Virginia, was mentioned, where it appears at intervals of eight and nine years alternately. Although, as regards this lo- cality, and perhaps some others, this hypothesis may be correct, it will not apply to all cases. In 1834, the C. septemdecim appeared in the neighborhood of Philadelphia and in the adjoining counties, and again in small quantities in Chester county, in 1836. Mr. Cassin expressed the opinion that there are two varieties, of the C. septemdecin, the larger and smaller, both of which appeared in this vicinity in 1834 ; they differ in size, and also in their note. The larger is the one commonly known as the seventeen year locust. Dr. Goddard then called the attention of the members to a plan which he had recently adopted for removing a disease, common and very fatal to newly fledged chicks, and familiarly known as " the gapes," and which he considered of importance to be known by agriculturalists. Upon opening ihe trachea of a chick laboring under the disease, he discovered there a parasitic worm, which obstructed respiration, 280 [June, 1843. and occasioned inflammation of the part. By injecting into the trachea a small quantity of a mixture of equal parts of spirit of tur- pentine and olive oil, he succeeded in destroying the worm, and removing all the symptoms, and in every instance saving the life of the chick.

July, 1S43, 283 MEETING FOR BUSINESS, July 25, 1843. Vice President Morton in the Chair. The Report of the Corresponding Secretary was read and adopted. The Committee to whom was referred the following paper, reported in favor of its publication in the Proceedings of the Academy. Descriptions of two Species, supposed to be new, of the Genus Tyrannula Swainson, found in Cumberland County, Pennsylvania. By William M. & Spencer F. Baird, of Carlisle, Pa. For the first of the species hereafter described, we propose the name of Tyrannula flaviventris, the bright yellow colour of the lower parts constitut- ing a striking feature. The other we have named Tyrannula minima, it being the least of all our North American Tyrannulse. The similarity in colour and size between a number of our small tyrant fly-catchers being very great, we have deemed it best to send with the specimens of the two described, skins of T. acadica, and S. Traillii, spe- cies which most nearly resemble them. By a comparison of the four, the distinctive features of each will at once be perceived. Tyrannula flaviventris, (nob.) Specific Characters. Above deep greenish olive, beneath bright sulphur yellow, sides and fore part of breast olivaceous. Tail emarginate. Third and fourth primaries longest. Bill brownish yellow beneath. Description of a Male. Form, $rc. Body rather stout. Bill broad and the sides convex. Tarsus longer than the middle toe. Wings rounded ; third primary longest, fourth slightly shorter, second one line shorter than third, and two lines longer than fifth, first shorter than fifth, but longer than sixth. Tail emarginate and slightly rounded. Colour. Bill above dark blackish brown, beneath light yellowish brown: Feet brownish black. Plumage of the upper parts deep greenish olive, crown of the head rather darker, the feathers having their centres dark brown. A narrow ring round the eye pale yellow. Lower tail coverts, abdomen, and linings of the wings, bright sulphur yellow, deepest on the 2S4 [July, 184 3 abdomen. Sides of the body, forepart of the breast, and sides of the neck, olive, lighter than the back, and inclining to yellowish on the throat. Pri- maries and tail feathers dark brown, the former bordered with grayish, and the latter with olive like the back. The lower row of lesser wing co- verts and the secondary coverts darker, tipped with pale yellow, that co- lour forming two bands across the wing. Secondaries darker than the primaries, and edged with pale yellow. Length 5 inches 4 lines ; extent 8 inches 8 lines ; folded wing 2 inches 9 lines. The sexes are similar in colour, but the female is generally rather smaller. Observations. This strongly marked species will at once be distinguished from every other by the deep yellow of its under parts. It resembles T. acadica of Gmelin (querula of Wilson) somewhat in form, but acadica by comparison will be found to be a larger bird, lighter olive above, and very pale yellow beneath. The tail of acadica is even or slightly rounded, in this species emarginate. We have no specimen of T. pusilla, of Swainson, but upon comparison with the description in Swainson and Richardson's Zoology of North America, (so favourably known for accuracy,) it appears to differ in the colour of the upper parts, pusilla being " intermediate between hair brown and oil green ;" our species is of a decided olive green ; the front of pusilla is "hoary;" in our species dark brownish olive; the bands on the wing- grayish white; in our species pale yellow; "throat and breast" of T. pu- silla " pale ash gray;" in this species the throat is yellow, and the breast olive tinged with yellow. This species was first observed in the spring of 1840, near Carlisle, Pennsylvania. During every succeeding spring since, it has been seen in greater or less numbers, and several specimens procured each year. Its habits are much like those of the other species of this genus; it frequents low thickets near small streams, is seldom found in large woods like T. acadica, or T. virens, and is a very unsuspicious bird, allowing persons to approach within a short distance, [t probably goes further north than Pennsylvania to breed, having never been observed after the latter part of May or beginning of June. Tyrannula minima, (nob. ) Specific characters. Above dark grayish olive, breast light ash gray, ab- domen and lower tail coverts yellowish white. Tail emarginate. Second and third primaries longest, first longer than sixth. Bill horn colour be- neath. Description of a Male. Form, &c. Body rather slender. Bill smaller than the other species of the genus. Tarsus slightly longer than the middle toe. Second primary July, 1S43. 1 285 longest, third nearly equal, and rather longer than fourth, fifth one line shorter than fourth, first intermediate between fifth and sixth. Tail emar- ginate and slightly rounded. Colour, Bill dark blackish brown above, pale horn color beneath. Feet black. Plumage of the upper parts dark grayish olive, crown somewhat darker, rump lighter and inclining to grayish. A narrow ring round the eye grayish white. Fore part of breast, sides, and sides of the neck light ash grey, middle of throat white, rest of the lower parts very pale yellow or yellowish white. Primaries and tail feathers wood brown, the former narrowly, and the latter broadly edged with olive. Lower row of lesser wing coverts and the secondary coverts darker, tipped with dirty white, that colour forming two bands across the wings. Secondaries also dark, like the greater wing coverts, and broadly edged with yellowish white. Length 5 inches, 2 lines. Extent 8 inches, 3 lines. Folded wing 2| inches. No perceptible difference as to colour or size between the sexes. Observations. This species will be recognized by its size, its slender form making it the smallest of our North American Tyrannulaa. In colour it most resembles T. Traillii, of Aud., but it is a much smaller bird, being nearly three-fourths of an inch shorter. T. Traillii has the breast and sides of the neck olivaceous ; in this species light ash gray; the tail also of T. Traillii is even. It differs from T. pusilla (comparing with the description of Swainson and Richardson as before) in having the wings more pointed, the second and third primaries being longest, and the firstlonger than the sixth; while in pusilla the third and fourth are longest, and the first shorter than the sixth. The upper tail coverts of pusilla are uniform in colour with the back ; in our species lighter : pusilla has the front " hoary;" in this species dark. The lower parts of pusilla are pale sulphur yellow, "approaching to siskin- green ;" in our species yellowish white : the under mandible of pusilla is yellowish brown; of this species horn colour. From the figure in the Fauna Boreali-Americana, pusilla appears to be a stouter bird, much deeper in colour beneath and having a broader bill. Its smaller size, and darker colour above, will distinguish it from T. acadica (being two-thirds of an inch shorter.) which species has also longer and more pointed wings, a much larger bill which is light brown beneath, and an even tail. This species was first observed and procured in May, 1839, near Car- lisle, Pennsylvania. Since then numbers have been observed and shot on every succeeding spring. Like the preceding, (T. flaviventris,) this bird does not frequent deep forests, but is found among the scattering trees which border our streams. It is rather shyer than T. flaviventris, and and does not, like that species, seek dense thickets. It also, most proba- bly, goes further north to breed, as after the last of May it is no longer to be seen. It visits us from the south in the latter part of April, generally making its appearance about a week before T. flaviventris. 2S6 [July, 1843. NEW BUSINESS. Mr. George R. Gliddon informed the Academy that he had recently received a letter from his father, John Gliddon, Esq. U. S. Consul in Egypt, dated Cairo, 18th June, 1S43, ex- pressing regret that the Egyptian Society had been unavoid- ably obliged to delay the answers to the geological queries addressed to them by a Committee of the Academy. These queries had been submitted to a special committee of scientific members, by whom it was discovered that they had been met (though under different arrangement) in a dissertation which Dr. Figari (a distinguished Italian naturalist, &c. and member of the Society) is preparing to be read and presented at the next general meeting of the Society, expected to take place on the 1st of July, and which would be published forthwith. Copies would be sent to the Academy with an official communication. Mr. Gliddon also stated that a copy of M. Linant's (chief engineer in the Pasha's service) Me- moir on Lake Maris, just published by the Egyptian Society, had been sent to the Academy, and would be presented as soon as received. ELECTION.

October, 1843.] 305 By permission of the Society, the Committee to whom was referred Mr. Conrad's paper, read at the meeting of 19th September, presented a report in favour of its publica- tion. Descriptions of a New Genus, and of twenty-nine new 3Eocene, and one Eocene Fossil Shells of the United States. By T. A. Conrad. Carditamera. C. carinata. Trapezoidal, slightly contracted from beak to base ; ribs about 18, profound, flattened on the back, square, carinated on the posterior margin ; posterior ribs rounded and the carina obscure or wanting; middle and anterior ribs about as wide as the interstices ; all the costse with transverse coarse pro- found wrinkled lines. Locality. Newbern, N. C. Compared with C. arata, this species differs, in being less ventricose over the umbonial slope, in having a carina on the ribs, more distant transverse strise, the beaks further from the anterior margin, and the posterior side narrower, with a more oblique posterior margin. C. protracta. Trapezoidal, elongated, compressed, widely contracted from beak to base ; dorsal and basal margins nearly parallel ; ribs about 15, the middle ones triangular and crenated ; posterior ribs rounded and having distant arched squamose coarse strise ; summit of the beaks scarcely prominent above the hinge line. Locality. Patuxent River, St. Mary's Co., Md. Arca. A. triquetra. Subtriangular, profoundly ventricose ; umbo very broad and prominent, beaks remote, profoundly incurved ; disk flattened posteriorly ; ribs about 30, narrow, not very prominent, square; surface of the valves with coarse crowded concentric imbricated lines; umbonial slope forming a right angle with the posterior slope ; cardinal area dilated ; cardinal plate narrow, the teeth small. Locality. Cliffs of Calvert, Maryland. This species differs from A. callipleura in having narrower ribs which are neither crenated nor longitudinally striated as in that species. The A. callipleura is not flattened posteriorly on the disk, and the umbonial slope is slightly arched in the middle, while in the triquetra it is somewhat concave. Nucuia. N. liciata. Ovate-acute, ventricose, with about 15 concentric lamelliform strise ; posterior side much shorter than the anterior ; anterior side slightly re- curved, with an oblique slight submarginal furrow, causing a slight emargination of the base near the extremity. Locality. Cliffs of Calvert, Md. 306 [October, 1843. Pectunculus. P. parilis. Orbicular, slightly oblique; height and length equal ; posterior superior margin obliquely subtruncated ; ribs denned by slightly impressed narrow radii ; radiating striee minute and obsolete ; marginal teeth prominent. Locality. Cliffs of Calvert, Md. Differs from P. carolinianus, in being oblique, narrower towards the beaks, less convex, and in the much less prominent ribs, &c. Pecten. 1. P. biformis. Inequivalved; superior valve nearly flat; inferior ventricose ; ribs 5 or 6, on the umbo, large, convex, with minute reticulated striee; from a concentric sulcus below the umbo, the ribs suddenly become less prominent, very wide and composed of fasciculi of smaller irregular ribs; ears equal, small. Locality. Petersburg, Va. Mr. Tuofney. This singular Pecten is allied to P. decemnarius, but the peculiar character of the ribs is a sufficient distinction. The lower valve, from which the description is chiefly taken, has large convex ribs above, longitudinally striated, and sepa- rated by a concentric groove from the numerous small ribs below ; the interstices have smaller costoe ; young shells have the superior valve frequently slightly concave. 2. P. tricenarius. Suborbicular; inferior valve convex, ribs 30 to 33, some- what unequal in size, crossed by minute lines ; sinus of the ear profound. Locality. Found with the preceding species by Mr. Tuomey. 3. P. vicenarhis. Suborbicular, inequivalved, the superior valve ventri- cose, the inferior plano-convex ; ribs about 20, somewhat flattened on the back ; ribs of superior valve narrower and more distant than those of inferior valve ; surface of both with crowded regular concentric wrinkles; ears equal, moderate in size; sinus of inferior valve not profound. Locality. Wilmington, N. C. Mr. Hodge. Teilina. 1. T.lenis. Subelliptical ; beaks medial ; anterior margin obliquely trun- cated, the extremity acutely rounded ; dorsal margins equally oblique ; posterior basal margin obliquely subtruncated; basal margin nearly straight in the middle and towards the anterior extremity where it is arched ; the extremity consider- ably above the line of the base ; posterior side with an oblique narrow fold. Locality. Cliffs of Calvert, Md. 2. T. arctata. Ovate, thin, slightly ventricose along the umbonial slope ; flattened in the middle of the valve ; dorsal and basal margins parallel ; pos- terior margin rounded obliquely inwards ; basal margin slightly contracted in the middle ; beaks slightly prominent ; posterior dorsal margin slightly sinuous ; surface with concentric prominent acute lines ; cardinal plate rather wide ; lateral teeth none. Found in North Carolina, by Professor Mitchell, of Chapel Hill. October, 1843.] 307 LuCINA. L. multlstriata. Oval, equilateral, slightly ventricose, with fine prominent closely arranged concentric and minute radiating lines; disk with two or more distinct undulations on the inferior half; beaks prominent ; dorsal margins profoundly declining ; anterior lateral tooth distinct, remote ; inner margin minutely crenulated; lunule elliptical, slightly impressed. Height one-third of an inch. Locality. Wilmington, N. C. Amphidesma. A. asquata. Longitudinally oval, convex, with about 17 laminated concentric stria?; anterior and posterior margins nearly equally rounded ; basal margin very regularly rounded ; beaks slightly prominent ; one cardinal tooth in the right valve, and no lateral teeth. Length less than one-third of an inch. Localities. St. Mary's Co., (Md.) Wilmington, N. C. Crassatella. C. turgidula. Oblong-ovate, slightly ventricose ; surface with coarse lines of growth, and concentric undulations obsolete except on the umbones where they are strongly marked and wide ; beaks submedial ; umbones flattened ; anterior dorsal margin straight ; posterior extremity truncated and nearly direct, more oblique in young shells; basal margin swelling a little anteriorly, posterior- ly straight to the extremity which is obliquely angulated. Locality. Calvert Co., Md. Allied to C. Marylandica, but has less prominent, more flattened umbones, which are widely and profoundly undulated. It is, also, more ventricose, and has a more regularly arched basal margin. Young shells of the two species are widely unlike each other. Crepidula. C. splnosa. Oval, ventricose, rather thick, with longitudinal rib-like series of thick, elevated, foliated, erect spines, and coarse transverse wrinkles ; dia- phragm sinuous, the margin profoundly sinuous. Locality. James River, near Smithfield, Va. Differs from C. cosiata, Morton, in wanting the numerous fine costfc, and in having fewer, much longer, and thicker spines. Fulgtjr. F. rugosus. Pyriform, with rather coarse rugose revolving lines, disposed to alternate in size, and very distinct numerous lines of growth ; whorls scalariform, with a tubcrculated carina, the margin of which presents a waved outline, the tubercles being obtuse ; spire prominent, profoundly channelled at the suture, the margin of the channel carinated in young shells. Length 3 inches. Locality. St. Mary's River, Md. Compared with F. coronatus, this species, when adult, is comparatively shorter and more inflated, with a shorter spire, much coarser revolving lines, which with the more numerous, more obtuse tubercles, give the shell a very different appearance from the coronatus. In an adult specimen of the latter species there are 13 spiniform tubercles on the body whorl. In the allied species 42 308 [October, 1843. when adult, there are 17 much less elevated, more irregular, and more obtuse tubercles. Buccintjm. 1. B. protractum.

Locality. James River, Va. Resembles Fusus cinereus of Say, but is much shorter in proportion, and has more prominent spiral lines ; but the folds on the columella constitute the most marked distinction. 4. B. sexdentatum.

VERBAL COMMUNICATIONS. Dr. Chaloner called the attention of the Society to a number of very fine specimens on the table of fossil bones of the Mastodon and Elephant, brought by Mr. S. H.Whipple, from Benton Coun- ty, Missouri, and forming part of a large collection in his posses- sion, and now arranged for inspection in this city. A list was presented by this gentleman, with an estimate of the weight of the specimens, which he supposed to exceed 2000 lbs., accompa- nied by the following statement: "These bones were found in the County of Benton, Missouri, about one half mile from the river Osage, 70 miles south of the Missouri river, at Boonville, in north latitude 38° 10', and west longitude 16° 40'." After adverting to the character of this portion of the county, which is broken up into ridges and rocky elevations of considerable extent, with intervening vallies, through which pass small streams of water, he says : "In one of the val- lies referred to, just at the point where a fertile bottom is connec- ted with a more elevated region, is a small marsh, perhaps of an acre in extent. One half of this marsh is covered by a soil differ- ent from that composing the marsh itself. This soil appears to 322 [December, 1843. have been derived from the ground immediately adjoining it, which is now a cultivated field, but was formerly covered with oak timber. The field has a gentle slope towards the marsh from a rocky ridge, composed partly of what appears to be limestone, in irregular columns, of from 10 to 20 feet elevation above the surrounding portion of the ridge, and its soil bears evidence of having been washed from the ridge, and, as has been stated, now forms part of the upper surface of the marsh. It was under this deposit, and at the depth of from two to twelve feet, imbedded in the marsh, that these bones were found, lying in the utmost confusion, and disorder."

The Committee, to whom was referred Mr. Conrad's paper, read November 21st, and the additions thereto read Decem- ber 1 .9th, reported in favour of publication. Descriptions of nineteen species of Tertiary fossils of Virginia and North Carolina, By T. A. Conrad. Anomia. Anoxia Ruffini. Subovate or suborbicular, irregular ; larger valve with concentric lamins, sometimes obsolete, often closely arranged towards the base, plicated on the margin ; disk with numerous irregular interrupted radiating fur- rows and lines ; hinge area wide ; muscular impression very large, ovate-elon- gated. Height of the largest specimen, two and a half inches. Locality. Pamunkey river, Kent county, Virginia. This fine large species was found by Edmund Ruffin, Esq., and I take plea- sure in dedicating it to a gentlemen distinguished for his science, and his suc- cessful and enlightened efforts to improve the agriculture of his country. Arca. Arca propatula. Rhomboidal, thick and ponderous; posterior side produced ; sides flattened, slightly concave towards the base; uinbonial slope rounded, rather elevated ; ribs about thirty-two, square, not profoundly prominent, about equal in width to the interstices, which have transverse imbricated lines ; ribs largest about the umbonial slope, very distinct on the posterior slope, which is con- cave towards the hinge line ; posterior margin oblique, concave, extremity wide- ly rounded ; summit of umbo moderately elevated, slightly retuse ; cardinal area wide, with diverging grooves; series of teeth slightly sinuous anteriorly ; teeth numerous ; at the posterior extremity, the series suddenly becomes dilated, and the teeth interrupted or tubercular; inner margin crenate, crence profound, and remote posteriorly. Length, four inches ; height, rather more than one and one-third inches. Locality. James river, below City Point. Petersburg, Mr. Tuomey ; Ware river, Gloucester county, Virginia, Mr. Kuffin. Perhaps this may prove to be an old specimen of A. arata, Say. 44 324 [December, 1S43. Arca scalaris. Obliquely rhomboidal, elevated, ventricose, ribs about twen- ty-three, broad, square, prominent, profoundly and robustly crenate, wider than the interstices, seven on the posterior slope, prominent; posterior slope flattened ; umbonial slope angulated ; summit elevated, narrowed ; anterior margin oblique- ly truncated ; anterior basal margin obliquely subtruncated ; posterior extremity subangulated ; beaks remote; area with transverse slightly impressed lines; cardinal teeth irregular, oblique towards the extremities of the hinge line ; within with furrows corresponding to the ribs ; margin profoundly crenate. Length, two inches ; height, one and a half inches. Locality. Petersburg, Virginia. Mr. Tuomey. Allied to A. incongrua, Say. The description applies to the left valve only, as the opposite one has not yet been found. Ctrena. Ctrena densata. Subtriangular, thick, convex, with robust lines of growth ; anterior margin obtusely rounded ; basal margin profoundly and regularly curved to the posterior extremity, which is subtruncated, direct, and greatly above the line of the base ; beaks central, summits elevated ; teeth large, robust, very pro- minent, three in one valve, and two in the opposite ; middle tooth of the right valve bifid ; lateral teeth elongated, robust, anterior tooth truncated, suddenly deflected at the extremity ; posterior tooth distant. Length, one and a half inches ; height, one inch and seven-eighths. Locality. Vicinity of Petersburg, Virginia. Mr. Tuomey. Rare. Mactra. Mactra triquetra. Triangular, thick, ventricose ; anterior margin obtusely rounded; posterior margin obliquely truncated ; extremity angular; anterior and basal margins regularly curved : posterior basal margin obliquely truncated, and the disk slightly flattened above ; umbonial slope forming a right angle with the posterior depression ; beaks slightly remote, central, summits profound- ly elevated ; lateral teeth robust; fosset small, ovate. Length, one and a quar- ter inches ; height one inch. Locality. Vicinity of Petersburg, Virginia. I found a single perfect valve of this species, which is much larger and pro- portionally shorter than M. congesta, and differs especially in the beaks being distant from the hinge margin. Venus. 1. Venus capax. Cordate, suborbicular, ventricose, with concentric lamel- liform prominent lines ; posterior margin curved, extremity truncated, direct, and remote from the line of the base ; basal margin profoundly curved ; lunule dilated, cordate, defined by a groove, and not distinctly impressed ; inner margin finely crenulated. Locality. Pamunkey river, Kent county, Virginia. Mr. Tuomey. This shell is of a more rotund, tumid form than any of the species allied to V. mtrcmaria, and much more capacious ; the lunule is shorter and wider. 2. Venus permagna. Subtriangular, cordate, profoundly ventricose, thick and ponderous, with coarse concentric recurved rib-like lines, elevated, closely December, 1843.] 325 arranged, and lamelliform on the sides; lunule cordate, elongated, defined by a deeply impressed line ; posterior side subcuneiforrn, extremity obtusely rounded or subtruncated ; cardinal plate broad: muscular impressions large; margin strongly crenulated. Length, seven inches. V.permagna, Foss. of Tert. Formations, p. 9. Locality. Neuse river, below Newbern, North Carolina. Miocene ? This is perhaps the largest Venus known : it is remarkably rough and pon- derous. In outline it approaches V. Rileyi, but it is greatly more ponderous and ventricose. The usual size is about four and a half inches in length. Artemis. Artemis elegans. Lentiform, regularly convex, with strongly marked rather distant impressed concentric lines ; on the posterior side these are closely ar- ranged and profound, forming prominent recurved lines, which become acute or lamelliform towards the posterior margin; posterior hinge margin elongated, slightly convex, oblique; lunule cordate, deeply impressed. Height, two and a half inches; length, two inches and seven-eighths. A. elegans. Fossils of Tertiary Formations, p. 30. Locality. Neuse river, below Newbern, North Carolina. Miocene. This beautiful shell is allied to A. concentrica, but is readily distinguished by its stronger remoter stria, by its convexity of disk, and its more robust anterior cardinal teeth ; the posterior teeth are less oblique, forming a wider space be- tween them and the anterior teeth. The posterior hinge margin is not so elong- ated, in proportion, as in the concentrica. I found this and the kindred species recent on Mullet Key, at the entrance of Tampa Bay, and, fortunately, specimens of the young of both, which show a marked difference in specific character. Loripes. Loripes elevata. Suborbicular, elevated, thin, ventricose, smooth, not oblique; beaks medial; hinge margins very oblique ; posterior margin truncated, direct, very regularly rounded towards the base ; anterior basal margin obliquely trun- cated ; cardinal plate thin, arched, with an elongated channel anteriorly ; cardi- nal teeth profoundly diverging. Length, nine-sixteenths of an inch ; height, the same. Locality. Neuse river, below Newbern, North Carolina. Miocene1? Proportionally more elevated than Loripes americana (Mysia,) thinner, not oblique like that species, and very distinct. Solex. 1. Soien directus. Linear, straight, except towards the summit, where it is slightly recurved, gradually widening from the hinge downwards ; basal mar- gin rounded slightly towards the posterior extremity ; anterior margin obliquely truncated, not reflected ; cardinal teeth, one in the "right valve, compressed, in the opposite valve, two, the superior one very small and near the extremity, the other somewhat distant, elevated, robust, slightly recurved. Length, four inches. Locality. Neuse river, below Newbern, North Carolina. Miocene 1 326 [December, 1843. I am doubtful of the geological age of the three fossils above described, as we know not the group among which they occur. 2. Soles ensiformis. Linear, slightly curved, gradually narrowed from the middle to the posterior extremity, which is subcuneiform ; anterior margin obliquely subtruncated. Length, three inches. Locality. St. Mary's river, Maryland. Miocene. TcHRITELLA. Turritella hipertlta. Turrited, thick ; suture profoundly excavated; whorls flattened, divided nearly in the middle by a deeply impressed revolving line, margined on each side by a fine impressed line ; inferior volutions carinated at base; lines of growth oblique, meeting at an angle at the groove in the middle of each volution. Length, ; width, seven-eighths of an inch. Locality. Vicinity of Petersburg, Virginia. Mr. Tuomey. This large species is very distinct from all others, and remarkable for the pro- found channel between the whorls. ScALARIA. Scalaria procera. Subulate, turrited, volutions scalariform, contracted in- feriorly, with obsolete revolving impressed lines : ribs thick, elevated, reflected, distant, with sharp triangular reflected aculeii on the shoulder of each volution; base with a revolving interrupted carina; aperture longitudinally obtusely oval. Length, ; width of body whorl, nearly half an inch ; three volutions from the base measure one inch. Locality. Vicinity of Petersburg. Mr. Tuomey. Pleurotoma. Pleurotoma multisecta. Turrited, with closely arranged deeply impressed revolving lines, and longitudinal robust prominent ribs; superior portion of each whorl destitute of ribs, with minute revolving lines, and a sharp revolving slight- ly undulating carina margining the suture; aperture elliptical, rather more than one-third the length of the shell. Length, one and one-eighth of an inch; greatest width, three-eighths of an inch. Locality. Vicinity of Petersburg. Mr. Tuomey. BuCCINUM. Buccinum harpuloides. Ovate, ventricose, with alternated revolving raised lines, and longitudinal slightly oblique rather distant narrow elevated ribs: spire scalariform, volutions five; base of the shell with an acute oblique carina; aper- ture half the length of the shell ; columella profoundly concave, with a promi- nent fold or carina on the angle formed by the obliquely truncated base ; a slight protuberance near the superior extremity of the aperture; margin of labrum nearly straight, suddenly rounded inferiorly. Length, one inch ; width, five- eighths of an inch. Fusus 7 Fusus 1 cannabinus. Fusiform ; whorls six or seven, with longitudinal rounded costae, and revolving prominent alternated lines finely wrinkled trans- versely; spire somewhat scalariform, elevated ; suture undulated; body whorl December, 1S43.] 327 abruptly rounded at base; beak short, subperforate, tortuous ; aperture with the channel rather less than half the length of the shell ; labrum with eight short dentiform prominent strice within. Length, one inch and a quarter. Locality. Petersburg, Virginia. Mr. Tuomey. Closely resembles Fusus cinereus, Say, but the whorls are more scalariform, and the body whorl much shorter and more abrupt at base ; the beak narrower and more tortuous. Terebra. Terebra curvilirata. Subulate, whorls with a revolving impressed line be- low and near the suture; beneath this line the whorls are convex; ribs longi- tudinal, curved, acute, dislocated by the impressed line ; revolving lines minute, crowded, obsolete ; columella sinuous. Length, one and a quarter inches. Locality. St. Mary's river, Maryland. Differs from Cerithium dislocatum, Say, in wanting the distinct revolving lines, and the small dislocated portion of the ribs are not of a tubercular form ; the aperture is longer and narrower. POLYPARIA. TtTRBINOtlA. Ttjrbiuolia pileolus.

Observations. In 328 species of organic remains already described, independent of minute and uncertain forms, 43 have been found in a recent state; and when to these are added numerous very small shells which are found in every careful examina- tion of marl from the various localities, the percentage of recent species may be pretty accurately estimated at about 11 or 12 per cent. This result I have ob- tained by a careful exploration of the fossilliferous beds, and two visits to the shores of Florida and Alabama to procure recent forms for comparison with those of the Miocene strata. The last trip furnished three recent shells before known only in the fossil state. Several species described in the preceding pages I obtained during a recent excursion to Petersburg, Virginia, at the kind invitation of Mr. Tuomey. In the course of a few hours examination of the marl in the vicinity in three or four days, I collected about 100 distinct species. This locality is peculiarly interesting, being the western limit of the Miocene, having a considerable eleva- tion above tide, and based on granite, it is the spot in which to search for the estuary and fresh water shells of the Miocene period. Mr. Tuomey has already found an extinct Cyrena, and a univalve not very unlike* Paiundina sub- purpurea, (Say,) whilst I discovered a species of Cerithium, identical with a shell which I found last spring inhabiting oyster beds in the Manitee river, near its junction with Tampa Bay. It is about the size and nearly resembles C. trilineatum, figured in Kiener's work. The elevation of the Petersburg Miocene is considerably more than 100 feet above tide, and as the rise decreases towards the sea, it is probable that the pri- mary rocks continued to be uplifted even after the era of the Miocene ; indeed how can we otherwise account for the elevation of fossilliferous beds, even of those of the Post-Pliocene period ? It is an interesting fact that the Miocene estuaries were inhabited by two species of bivalves, now extinct, of the same two genera which still occur in simi- lar situations in Florida and Alabama, that is at the confluence of rivers and bays, where the water is nearly fresh. These genera are Gnathodon and Cyrena, both of the family Ctrenad.tj. The extinct Gnathodon has a considerable resemblance to the recent species, but the Cyrena is widely different from the living shell. These fossils are frequently water-worn, always with disunited valves, and appear to have been transported. Occasionally a specimen occurs not in the least abraded, a circumstance which indicates the vicinity of the Petersburg deposits to the mouth of a river. The strata occur in a meadow, and consist of blue marl of a sandy texture, often intermixed with small gravel, and of ferruginous sand, full of shells ; there is here also a proportion of gravel, of rounded quartz, occasionally of large size. Water-worn fragments of bivalves are abundantly intermingled with entire shells, and many species occur with connected valves. This is particularly the case with the burrowing shells, as Panopoea, but also, though less frequently, with the large Venus tridacnoides, Crassatella undulata, Astahte concentrica, Cytherea albaria, two species of Chama, and even two species of Ostrea are not uncommon ; but there is nothing like an oyster bed in these strata which might indicate shoal water. The • P. glaber, (Terbo glaber, Lea.) December, 1843.] 329 proportion of oysters to the other bivalves is about the same which the dredge furnished at the mouth of Cape Fear river, N. C. at the depth of 8 fathoms. "With the many interesting bivalves of Petersburg I found a valve of the beautiful Pholadomya abrupta. which Deshayes has referred to Panopoea. I carefully removed the marl from the hinge, in order to ascertain if there was an erect curved tooth as in Pan- opcea, but the hinge proved to be destitute of any kind of tooth or process, and closely resembles that of the recent Pholadomya. Two characters, therefore, remove this shell from the genus Panopcea,- the pearliness of the substance and the absence of a cardinal tooth. A true panopoea is never pearly, any more than a Unio is ever otherwise. Observations on the Lead Bearing Limestone of Wisconsin, and descriptions of a new genus of Trilobites and fifteen new Silurian fossils. By T. A. Conrad. As the galeniferous limestone of Wisconsin and Galena has attracted the attention of our most distinguished Geologists, who have endeavored to assign its relative position in the scale of formations, I hope it may not be deemed pre- sumptuous if I endeavor to assist in settling a question of so much importance. The difficulty has hitherto arisen from the scarcity and obscurity of characteris- tic fossils, which is now in a great measure removed. Some years since I had the pleasure of examining a series of organic remains collected by Richard C. Taylor, Esq. at the lead mines in Wisconsin, and then distinctly recognized the species which belong to the Trenton limestone of New York, a rock which, in my first report on the Geology of New York, I showed to be an independant formation, and entirely distinct from any above or below it. Since then I have proved its occurrence at Cincinnati, in Ohio, and at Carlisle and Bedford Springs, Pennsylvania. In these remote localities the fossils are generally the same species, and the group of a unity which admits not of doubt or ambiguity. The specimens found by Mr. R. C.Taylor are chiefly from the limestone below the lead, and consist of Bellerofhron bilobatus, (Sowerby.) There are also specimens of fossiliferous limestone from Cassville, Wisconsin, of the same age, containing a Trenton limestone species of Orthis, like C. callac- tis, a Naculite, occurring also near Middleville, N. Y., Belleuofhron bilo. batus, a Strophomena like Orthis alternata, Sowerby, a common shell in the New York Trenton limestone, and an Orthis resembling O. tcstudinaria, still more abundant in the same rock. In the same collection are carboniferous fossils, in limestone and in chert, from St. Genevieve, Missouri. The species consist of a large Bellerophron, three species of Productus and one of Atrypa, all of which are found only in the carboniferous or mountain limestone. I am indebted to the liberality of Mr. Stephen Taylor, who has recently re- turned to this city from Mineral Point, Wisconsin Territory, for an opportunity 330 [December, 1843. to investigate some organic remains of more than ordinary interest, which that gentleman procured at the lead mines. Accompanying these are specimens of fossiliferous limestone, shells, and fragments of Trilobites in beautiful relief upon the surface, and so familiar and characteristic, that at the first glance I recognized the Trenton limestone of New York. The most prominent of these fossils consist of the trilobites, Ceratjrcs pleurexanthemus,Is
