from the eyes of the Falco Jagopus: he also communicated
the fact, that the bird lived at least an hour after it had re-
ceived a shot through the ventricles of the heart, allowing the
escape of blood; which fact was certain from the kind of
shot perforating the heart being of that size used at the first
fire only; the bird being brought to the ground by a subse-
quent discharge.

Dr. Goddard also made some remarks upon the anatomy
of this membrane, and the uses to which it is adapted.

Versat 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:
Ist. to planes of deposition; 2dly. to tansverse planes or
joints ; 3dly. to faults.

By special permission, Prof. Johnson in the chair,

Dr. S. G. Morton made soimne 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 material 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

8 . [Apriz, 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 g 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 filied. 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 cubie 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.

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

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 lamine,’’ 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 laminz 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 lamine 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, 1841.

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 laminee, 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.

May, 1841.] 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 been 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 would 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.

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.

“‘T 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 Gothlandica,
Turbinalapsis bina, Strophomena euglypha? Atrypa_prisca.
To which 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. basaltica, Gorgonia infundibuliformis? the last being more
common in the latter formations. (udlow.) 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 eccentrica.

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 Becki, [sotelus —, Pentacrinites 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 plic, 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 um-
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.—Oblong, 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.

was collected by Mr. J. F. Watson, of this city.

~

22 (May, 1841.

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 lamine 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 im some parts 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 se

{t contains of carbon, not volatile by simple heat, 67.62 «
And when fully incinerated, leaves of reddish grey

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.”

Warirren Communicarions.—Mr.J.S. Phillips read descrip-
tions of two new American species of the genus Helix: viz.

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
strie ; suture strongly impressed; aperture compressed, con-
tracted by a groove behind the outer lip ; outer lip moderately
reflected ; within the edge of the aperature 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. Nuttal.

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, um-
bilicata, substriata; apertura compressa; labro acuto, uno vel
duobus dentibus lamellosis ; base rotundato ; colore albo corneo.

Shell moderately elevated, lenticular; rather thick ; epidermis pale
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
lenticular form.

Mr. T. A. Conrad read a paper descriptive of twenty-six
new species of Fossil shells, discovered by him in the Medial

Professor Johnson made some remarks on the magnetic
phenomena attending the congealing of cast-iron.

34 [ June, 1841.

To observe the time and degree of rapidity of resuming the mag-
netic power bya massof melted iron,a bed was formed about3 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 ofthis 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 aline 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 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

extremity; but on reversing its position in the bed, the end which
had before beena north pole was made a south one; and vice
versa.

Dr. Morton made some remarks on the Ancient Peruvians ;
that extraordinaay 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 ata 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
numerons 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 thatrelates 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 [Junz, 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 Peru-
vians.

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. J)’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 whick is within 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
yet decided. Supposing this to be the fact, we may inquire how it
happens that the Incas should have soentirely abandoned the prac-
tice of distorting the cranium, especially as this, among the A yma-
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.

OQ
pie

i

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.

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 tothe beautiful and instructive work of M.
D’Orbigny, entitled “«L’Homme Americain, considéré sous ses
rapports physiologiques et moraux.”” These works were at the
same time placed on the table for inspection and comparison.

Versat Communcations.—Mr. Clay remarked that on ex-

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
proposes 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 653 lbs. and the
roes 4lbs. 6 oz. 2dr. 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.

Written Communications.—Professor Johnson submit-
ted the result of his experiments “ On the relation between

thracites.”’

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. Itwas the first step in this inquiry to mark the relation

by external characters. These in the Welsh coal are, Ist. A
structure often lamellated, and tending to separate on the surfaces
of deposition, owing to the quantity of carbonaceous clod which
occupies the dull seams between the bright plies of coal.

2d. The abundance and width of the reeds constituting the
charcoal 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 pro-
per, or to the carbonaceous clod partings of the seams.

The next circumstance worthy of attention in tracing the re-
lation of coals, is their specific gravity ; and this in the Welsh an-
thracite is from 1.336 to 1.372, not greater than that of many bi-
tuminous 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 percent.

Mr. Mushet makes it from 6.66 to 7.80 inthe 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 tothe
Inyscedwyn coal, is the coal of Lyken’s valley, situated in the
northwestern fork of the southern coal field. Thiscoal hasall the
exterior characters of the Welsh anthracite; containing in many
samples a large portion of carbonaceous clod, with well marked

vegetable impressions ; and incolour, structure, and varieties of
surface, 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 pro-
portion 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.

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 developement 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 percent. of pig metal of a lively grey color,
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 de-
cided 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 amount,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 expe-
rience in other anthracite furnaces.

Versat Communications.—Dr. B. H. Coates stated, that
out of about 20 stalks of bearded wheat, which he had recent-
ly examined in Moyamensing, and which were selected as
not having been able to develop their seeds, the greater part
presenting 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 thecavity of the straw,
and the inside had the appearance 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 fami-
liar Cecidomyia of Say. One of these was empty; and the
separation 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 antenne. Its general aspect resembled that
of atipulide fly. After a partial inspection by a gentleman
who had bestowed much labour on Entomology, the impres-
sion was received that it did not belong to the genus Cecido-
myia; 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

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 Nichol’s His-
tory of Leicestershire, which bore on the same question; viz.
that in the reign of one of the Stuarts, orders were sent to a
Sheriff of Staffordshire to discontinue the burning of Ferns

during a Royai 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 moré extended series of facts may be
collected and compared.

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 Botannical com-
mittee having examined the collection of plants lately pre-
sented to the Academy by Wm. Hembel, Esy., (being that
portion of the Herbarium of the late Prof. C. 8S. 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 So-
ciety be presented to Mr. Hembel for the same.

On behalf of the Committee,

R. BrinGeEs,
W. S. ZANTZINGER,
G. Watson.

The Botanical! committee also reported that the portion of
the Society’s Herbarium placed in the hands of Drs. Torrey
and Gray, of New York, for arrangement, had 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,”
reported in favour of publication.

Dr. Morton announced that, agreeably to appointment, he
had prepared a Memoir of William Maclure, Hsq., 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.

The following members constitute the committee :—Dr.
Goddard, Dr. Elwyn and Mr. Phillips.

The Society then proceeded to ballot for Corresponding
Members, when the following gentlemen were duly elected :

Written CommunicatTions.—The Corresponding Secretary
read a letter from Mr. Benjamin Silliman, Jr., acknowledging
the receipt of a letter announcing his election as a corresponding
member.

VerRBAL CommunicaTions.—Dr. Morton (Prof. Johnson taking
the chair,) made the following communication.

“T submit to the inspection of the members eight skulls of the
ancient Mexican race, for six of which I am indebted to Don J.
Gomez de la Cortina, and for the other two to Dr. John P. Macart-
ney, 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. Oromres.—Four in number, with the high vertex, flat occiput,

Juxy, 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 largest of these heads gives 92 cubic inches of internal
capacity ; the smallest, that of a female, only 67.

2. Cuecnemecan.—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 ourera. They were nomades
and hunters, but rapidly acquired the arts and civilization of
their predecessors.

3. TrascaLan.—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 pre-
vious 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 gentlemen from whom
I received them, of their having pertained to individuals of those
nations.

The two remaining crania are supposed to be those of Azrecks,
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 underthe name of Aztecs
or Mexicans, governed the country at the epoch of the Spanish
invasion, A. D. 1521. The Aztecs were a*brave and intelligent
people, but remarkable for bloody rites, both in their warlike and
religious observances. They were lesscultivated than the Toltecas,

52 [Jury, 1841.

but 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
configuration 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
intellectual, character..”

54 [JuLy, 1841.

A letter was read from Dr. M. E. Goheen, dated Monrovia,
Africa, April §, 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 read from Professor John Locke, of Cin-
cinnati, Ohio, in answer to the announcement of his election
as a corresponding member.

Verspat Communications.—Mr. 8S. 8S. Haldeman commu-
nicated 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. Swainson in the ““Menageries,”’
(p. 298 of the Cabinet Cyclopedia,) 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 asingle individual
of this species to occur on this part of the Susquehanna
river, (50 miles above tide water.) Wilson states that it is
found on the Delaware.

4. 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 larve from the hollow of
the straw of wheat, inthe upper joint, obtained from a locality
near Germantown, in which they were stated to be numerous.

Juny, 1841.] 55

No pupe 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 of 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 influ-
ence 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 :

Larve 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 antennee, 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 that of a lepidopterous
insect, 11-2Gths ofan 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 ;
around hole through which it could have entered, penetrating
the cell in which it was feeding, and also the leaf-sheath with-

56 (Jury, 1841.

out; preferred i's own cell toa 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.

Writren Communications.—A letter was read from Mr.
J. G. Anthony, in reference to the shells presented by him
this evening, with a proffer of further services.

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 Lukens.

Dr. B. H. Coates stated that Miss Morris had seen a Tipu-
lide fly in the act of placing her eggs on or ina grain of
wheat. This fly and these eggs she had in good preservation.
On comparing it with Le Sueur’s drawingyshe could see no
difference, except that the antennz were not quite so long,
and that the small nerves of the wing were more clearly de-
fined and strongly marked. She had also found a flaxseed
pupa in the cavity of the straw, with no hole, crack or visi-
ble mark where the larva could have entered. This pupa
she has examined with a microscope, and she can detect no
difference in it from that on the outside. This too she has
carefully preserved.

These important facts and specimens may, in the convic-
tion 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
prepared a list of the dates, in order that naturalists may be at no

58

loss 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.

The date of publication of the monthly issues of the first
volume are printed in and bound up with the text.

Written Communications.—Miss M. A. Morris, of Ger-
mantown, Pennsylvania, through Dr. B. H. Coates, submitied
the following “Observations on the development of the Hes-
sian Fly,” dated August 6, 1841.

«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 larve 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 browncolour. At this early period the larve
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 larve near
the root had left the inside of the straw,and become pupz 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 onthe grain. Thus interrupted, she piaced 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

AvaustT, 1841.] 67

-larve 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 larve.

From June 20th to July 10th, the flies continued to deposit their
egos onthe grain; though on the last mentioned date but few were
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 larve 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 Ceraphion destructor ; two of which
I send with the Cecidomyia.

From the sheaf of wheat I have the following results. Many of
the larve perished; some became pup 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 Ceraphion destructor ; some
of which are destitute of wings. A small number of pupe 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 [Aueust, 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.

Wrirtren Communicarion.—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.

He adverted 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-

AveustT, 1841.] 69

ous animals as strongly marked as in those of the viviparous
class. That they give acertain 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
along 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 varicus 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 [Auveust, 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 afford 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 primordia of 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.

Auveustr, 1841. ] 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 toa 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.

VERBAL COMMUNICATIONS. «

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; anda large
specimen furnished by Mr. Jacob Thomas of Beaver Meadow, was
exhibited, showing the truncated borders along the lines of separa-
. tioa 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
striz 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 [Aveust, 1841.

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 orgunic 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 from 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 often 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,

Aveust, 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 Conifer, 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 Cycadew, have been detected.

Mr. S. S. Haldeman submitted “ Descriptions of two new

tinuous, as in Cyclostoma. Length 3 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 isan Amnicola. Me-
lania integra, Say, is an Amnicola also.

Physa globosa.—Shell globose, translucent, spire very short
and rounded ; aperture very wide, occupying considerably more
than half the entire area of the shell; fold well marked, whorls
three. Length 1-5 inch. Hab., mouth of Nolachucky river,
attached to submerged rocks, in the rapids.

Oxss.—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 examined the animal of Ancylus, cannot have failed to ob-
serve 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 impossible 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. Itis 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.

“ Description of two new species of Fossil Scutella, from
South Carolina, by Edmund Ravenel, M. D.

“Scutella Caroliniana.—Specific character: nearly round;
slightly convex above; posterior margin truncated; ambulacra
short, elliptical, the two posterior slightly curved and nearly a
third longer than the others; in a line with each there is an ob-
long perforation extending almost to the margin; between the two
posterior ambulacra there is another perforation, longer than the
others, and more central, at the extremity of which, beneath, near
the mouth, isthe vent. Mouthcentral; diameter about six inches.

Scutella macrophora.—Specific character: subovate thick;
margin thick, truncated posteriorly ; notched slightly opposite the
anterior ambulacrum ; more deeply, opposite the lateral, and still
more so opposite to the posterior ambulacra. Ambulacra ellip-
tical ; the posterior pair long, and gracefully curved, so as to give
room between them, for a very large irreguiar 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 per-
fect specimen, and that is not quite 23 inches in diameter.

In examining these fossils in the light, the surface exhibits
bright crystalline faces ; the material of the shell seems to have
become crystallized since the destruction of the animal matter.

82 [SerremseR, 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
species of Pecten, of one or two Ostrex, a Plicatula and a Bala-
nus, are occasionally met with, while imperfect casts of numerous
species are very common.”’

The calcareous deposit to which the preceding fossils belong,
is the newest cretaceous formation of Dr. Morton, who first de-
scribed 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 ferrugi-
nous sand strata in New Jersey, North and South Carolina, Ala-
bama, &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 Maestricht, may prove, as Dr. Mantell has suggested,
to be a link between the chalk and the tertiary beds, without
being contemporaneous 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 in-
habitants. 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 te 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 further trouble.

SEPTEMBER, 1841. | 83

Mr. Quinby adverted to the celebrated ruins of the T'emple of
the Sun at Huanuco viejo, (Tiaguanico*) the Cyclopean fortress,—
the 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 aremarkable
state of preservation. These ruins, as is well known, date be-
yond the dynasty of the Incas, to a people, however, of the same
race, and probably of nearly similar political and religious institu-
tions,

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 attenu-
ated 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 cf 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

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 Arnazon to
the Atlantic ocean, a distance of five thousand miles.

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 natural-
ists might determine to whom to credit species, and what names
shall have priority. With a view to call the attention of the Aca-
demy of Natural Sciences to the subject, | have thrown together
some of the opinions and arguments urged by different parties,
in the hope that eventually some different 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, be-
cause 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 circumstances 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 to
know what has been done in the case; while specimens will re-
main unlabelled and unknown, because no one is particularly in-
terested in publication; but if priority of publication be the stand-

10

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 commit-
tee to whom the paper is referred might remain in it for months,
and in some cases years, and in the meantime 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 has 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 altera-
tion 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 described, he would have made his researches in
another quarter.

Another reason is, that by making mere reading the standard,
ail who were not present at the time, or had access to the minutes
of the society, might remain for a long time in ignorance ; espe-
cially as a paper might not be recorded until reported on by the
committee, who might retain it for years when the volume ap-
peared 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 ornot. In
this way the numerous specimens which are constantly scattered
through various collections would remain a long time undescribed

SePTEMBeER, 1841. ] 87

and 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 so-
cieties 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 descriptions 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 publica-
tion contribute greatly to the interest of science generally, in pro-
moting 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 [SerremMseER, 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 subdivided, 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 spe-
cies, because it is associated with another series of species, or be-
cause the termination of its latin name be altered to suit the al-
tered 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 Linnzus to Lamarck as an
authority and precedent for their own innovations and appropria-
tions. 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 cha-
racters of a group, a species, 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 descrip-
tion; and if in the progress of science, new divisions of genera,
or translations of species from one genus to another be found ne-
cessary; then credit the generic change to the constituter of the
genus, and the species to its original describer: thus Planorbis
Corneus, Lin. Lam. This, besides being sirictly just to all par-
ties, 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, SerpremMeEr 28, 1841.

Dr. Gopparp in the Chair.

The Corresponding Secretary’s report was read and
adopted.
The committee on Mr. Haldeman’s paper, “ Description of

two new Freshwater Shells,”? reported in favour of publica-
tion.

The committee on Dr. Ravenel’s “ Description of two new
fossil species of Scutella,’”’ 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, having carefully examined these inte-
resting and important matters, respectfully recommend the pub-
lication of Mr. Phillips communication in the bulletin of the pro-
ceedings 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-
ture, 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 pro-
found investigation and research, and secure to them the harvest
they may achieve, and thence facilitate the acquisition of precise
knowledge 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 descriptions thus put forth, are entitled to, should

90 [SepreEMBER, 1841,

receive the sanction of, 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 discoverics were read before a scientific society, and
without reference at all to the time of printing or general circu-
lation. But this seems to your committee, a very uncertain and
vague expedient, the source of perpetual embarrassment and con-
fusion; and much of the retardation of the spread of knowledge
may be attributed to this cause. Many societies issue their tran-
sactions 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 ad-
duced to warrant their conclusion—that the most obvious and
rational criterion 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 as-
signing credit, where it is justly merited,—thus wresting from
the naturalist the honour acquired by his oftentimes onerous and
unrequited toil,—your committee trust, that the Academy of Na-
tural Sciences of Philadelphia, will sustain them in an expression
of decided disapprobation of a practice, so fraught with evil,
doing injury alike to science and to its collaborators.

WRITTEN CommuNIcAtTIONS.—Dr. Morton read a letter ad-

South Carolina, accompanying a communication on the Fauna
of North America, which was submitted to the Soeiety for
publication, viz :

“Descriptions of New Species of Quadrupeds inhabiting
North America. By J. J. Audubon and J. Bachman.

VESPERTILIO monticola. Mountain Bat.

V. Vespertilione subulata brevior; auriculis brevioribus; tragis non ex-
cedentibus dimidiam longitudinem auricrle; colore fulvo.

Mouutain Bat. Smaller than Say’s Bat, (V. subulatus;) ears shorter ;
tragus less than half the length of the ear; colour yellowish brown.

Upper fore-teeth bilobate, ears moderate, naked, erect, rather broad at
base ; tragus linear, subulate, body small; wings long; tail projecting, a
line beyond the interfemoral membrane, which is slightly sprinkled with
hair above and beneath.

Colour. The nose and chin are black; ears, light brown; wing mem-
branes, dark brown. The whole of the fur of the body, above and beneath,
is from the roots of an uniform yellowish-brown colour.

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.

N. B. The tragus in Say’s Bat is 43 lines in height. Several specimens
of this Bat were obtained during summer, on the mountains of Virginia, at
the Grey Sulphur Springs. They were very uniform in size and colour.

VEsPERTILIO Virginianus. Virginian Bat.

V. (Virginianus) vespertilione monticula paululum longior, auriculis
paululum longioribus magisque acutis; dentibus primoribus maxille supe-
rioris simplicibus; interfemorali membrana nudaé; corpore supra fuligineo-

Virginian Bat.—A little larger than the Mountain Bat ; earsa little longer
and more pointed ; upper fore teeth simple; interfemoral membrane naked ;
sooty, brown above, ash brown beneath.

Dental formula, incisors, 2—?> Canines, !—l.
6 1—1.

In size, this species is intermediate between Vespertilio Carolinensis, and
V. subulatus. The ear is naked, less rounded, and more pointed than either
of the other closely-allied species. The tragus is very narrow, linear, and
less than half the length of the ear. 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. Carolinensis) or bilo-
bate, as in Ves. subulatus and Ves. montanus, are simple.

Colour.—The nose, upper lip and under-jaw are black; wings dark
brown. The back is sooty brown; on each shoulder, at the insertion of
the wing, there is a circular black spot about four lines in diameter; on
the under surface, cinereous brown.

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
MeMartrie’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 [OctopEr, 1841.

mulating 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 Boreali 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 statiug, 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 white in winter,
we are not ceitain that the species we are about to describe is identical
with the specimens he referred to.

Mustexa 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 more 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, as 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 tban 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
odeeg of the mouth, and by a well-defined line, along the neck, inner

parts of the fore legs, the sides and the thighs, and tapering off to a point
at the tarsus. 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.

The specimen of the American Brown Weasel, described above, was ob-

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} south latitude. The southern
points of Florida and California will, in this case, be the southern bound-
ary of our North American Fauna. Ourspecimenwas received from North
California about latitude 40°.

Ermine. It appears to be somewhat shorter. The toes and nails are more
thinly clothed with fur; the ears are narrower and longer. :

Colour.—The nose, sides of the face to above the eyes, and the ears are
dark brown: end of the tail black; a small spot on the head, between the
ears; the forehead, a broad line extending beneath the ears; the chin and
the throat white. The whole upper surface is a light fawn colour; be-

A. (fulva.) Corpore longo ac tenui; naso acuto; auriculis et pedibus
longis; velleri tereti ac nitente ; supra fusca; subtus cano-fusco.

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 coy-
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.

A. (nasuta.) Arvicola Pennsylvanica longior; cauda capite breviore ;
pedibus tenuibus; calce brevissima; corpore supra ferrugineo-fusco ;
subtus ex cinereo et flavo variegato. :

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.

though not described, by Rafinesque, in the American Monthly Magazine,
under the name of Lemmus Noveboracensis. 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.

ARYICOLA scalopsoides. Mole Arvicola.

A. (Scalopsoides.) Capite crasso; naso obtuso; vellere curto, molli,
bombycino instar velleri Talpz; 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
(Psamomys 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.

Incisors, > Canines, = Molars, = | 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 athumb. 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 earth
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 | kept in confinement for several
months, refused animal food of every kind, and fed only on grains.

Mus (Calomys) aureolus. Orange Coloured Mouse.

Mus (aureolus) Auriculis longis ; cauda corpore curtiore ; corpore supra
aureo; subtus flavo-albente.

Mouse with long ears; tail shorter than the body; bright orange co-
Youred 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.
Mamme 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.

In symmetry of form and brightness of colour, this is the prettiest spe-
cies of Mus inhabiting our country. 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 Kaas
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. Two other species have
ee described from South America. Mus (calomys) elegans and graci-

ipes.”

Yellow bellied Marmot.

Upper parts, grizzled yellowish white and black; crown of the head
chiedy black ; under parts, deep yellow ; sides of the muzzle, yellow; point
of the nose, tips and chin, white; feet, brownish yellow; tail blackish-
brown, all of the hair tipt with brownish yellow. ;

The fur on the back is greyish-black at the base; on each hair there is
then a considerable space occupied by dirty yellowish-white, which is
gradually shaded towards the apex through brown into black; tips of the
hairs yellowish-white ; hairs of the belly, greyish-black at the base ; hairs
of feet, many of them blackish at base; cheeks, grizzled black and white ;
the former colour prevailing: a rusty brown patch on tbe throat, borders
the white hairs of the chin; whiskers moderate black; feet entirely naked
beneath.

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. The head is
narrower, the toes are smaller, and claws only half the length of the Arcto-
mys empetra.

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; bead short, ears large,
thickly clothed en 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,
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.

The two specimens, which in other respects were very similar, differ a
little in the colour of the head; one being lighter coloured, the head being
dark greyish-brown.

Neck very long; tail longer than the body; hair short, rigid, adpressed,
glossy ; the whole body jet black.

Form.—The usually long neck of this species, together with its long and
slender body, and smooth, lustrous hair, give it the appearance of some
species of weasel, which has suggested to us the specific name. The ears,
which are of moderate size, are nearly naked, there being only a few hairs
on the borders; feet covered with very short hairs, which only reach tothe
roots of the nails. The tail, which is long, but not bushy, is moderately
distichous.

Colour.—The hairs, in every part of the body, are from the roots to the
extremities, of an intense glossy black.

The specimen was received from California, and has the appearance, from
its thin covering of hair, nearly destitute of the soft fur usually found in
the squirrel, of being a native of a warm climate. "

Remarks.—This species differs widely from all the other varieties and
species of Black Squirrel in our country. It is destitute of the white nose
and ears of Sc. capistratus; it has shorter and coarser hair than Sc. niger,
with none of the white tufts invariably found in that species; and has a
smaller body, although a much longer tail, than Se. Auduboni, with none
of the white, yellow and brown annulations in the hair, which characterize
that species.

Rust-bellied Squirrel. :

Light grey above, reddish-brown on the shoulders; beneath, bright

Form.—This species, which is a little smaller than the Carolina Grey
Squirrel, possesses great symmetry of form, and, in shape, resembles the
latter species. The ears on both surfaces are thinly clothed with hair ; tail
longer than the body. ; :

Colour.—Teeth yellow; nails brown; point of nose and whiskers, black ;
ears, on the outer edges, tinged with brown; within, grey; behind the
ears, on the neck, a line of soiled white. On tke 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,

Tail broad, and very distichous; dark greyish-brown above, white be-
neath.

Form.—Intermediate in size between Sc. cinereous and Sc. leucotis; ears
moderate, thinly covered with very short hairs on both surfaces; tail
longer than the body. .

Colour.—Teeth orange; whiskers black; nose dark brown; ears light
brown. Above the ears, a tuft of soft, cottony-like fur. The hairs on the
back, which are short, are cinereous at the roots, then light brown, tipt
with brown and black, giving it so much the colour of the English Hare,
that we concluded to borrow from it our specific name. On the sides, the

colour is a shade lighter than on the back. The tail, which from the broad
white tips of the hair has a white appearance, is brown at the roots, aud
three times annulated with black. The upper lips, chia, neck and
under-surface, including the inner surface of the legs, white; the
hair being of this colour from the roots; feet, a soiled yellowish white. On
the outer surface of the hind leg, above the heel, a small portion of the fur
is brown. There is also a spot of the same colour on the upper surface of
the hind foot.

This species, in its general appearance, so much resembles some varieties
of the Sc. cinereous and Sc. leucotis, that, had it not been for its distant
western locality, we should at first have been tempted to set it down, with-
out further examination, as one or other of those species. There can, how-
ever, be no doubt, from its differing in so many details of colour, of its
being distinct from either. ~ "

Scrurvs molli-pilosus. Soft-baired Squirrel.

S. molli-pilosus. Cauda corpore curtiore; dorso fusca; lateribus et
colli partibus rufis ; abdomine cinereo.

Soft-haired Squirrel.

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 tinged 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.

Western Squirrel.

Fur long and soft; ears narrow; tail longer than the body ; head, dorsal

OcToBER, 1841.] 1038

In size, this species is a little larger than the Northern Grey Squirrel, (Sc.
leucotis,) and may be compared with the black variety of that species. The
ears, which are elliptical in shape and narrower than ia 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 aline
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. Onthe
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 no annulations in the hairs of the tail.

When old father Linnzeus comprehended the whole of his description of
an American Squirrel in the single word, niger, he was not aware of the
number of species of Black squirrels which should yet be detected in our
western world, and the perplexity it would give to his successors in decid-
ing on the species to which he referred.
There are now no less than eight North American squirrels, which are
either permanently, or in some of their varieties, black.
The present cannot, bowever, 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.
Bears considerable resemblance to C. similis, from which it

may be distinguished by the more elevated beaks.

N. B.—Pisidium abruptum (p. 53,) is not distinct from P.
dubium, Say.

VERBAL CoMMUNICATIONS.—Mr. Haldeman 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, &e. 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 inner being received into a superficial fossa of the outer whorl.
Internal and external margins armed with pointed tubercles,
between which are delicate, gently curved costae, 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 specimens the internal marginal tubercles are very indis-
tinct ; but in other respects this species appears to be but little
modified by age.

2. 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 costze 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 cost, 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 ; cost 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 [Ocrossr, 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. Pl. xvi. fig. 1,2,3. Large and
beautifully preserved specimens.

Ammonites placenta, (Dekay,) Synop. pl. 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.
fic. 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. Pl. 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. Pl. 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 coste, which diminish
and become almost extinct at the internal peripheral margin :
external periphery sub-angular, and undulated by the transit of
the coste.

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 24 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 [Octozer, 1841.
thirds convex, the internal third concave, 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.

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.

CHAMZLEO 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 frout 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

112 [OctopEr, 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
hody, 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.] 118

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, axillee, 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 im 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 [OcropER, 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 hands,
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.

OcroBEr, 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, placed 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 bea 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-
tebree ; and instead of 19 dorsal and 4 lumbar, had 25 dorsal
and 10 lumbar vertebrae, making the number of bones in the
spine too great by 11. The bones articulated with the 2nd
and 4th ribs were cervical vertebree. The spaces between
the vertebrze 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 Ist 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

resemble a snout. The tusks were distorted laterally, so as to
occupy a space of 18 feet in width. °

Scapule and tlia.—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.

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 intoa 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

granite, as in Rhode Island, Massachusetts and Virginia, on the
older members of the secondary, as inthe 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, Ist, 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 alittle to
the east of south, and the dip of course to the north of east. The
mining operations are in general very troublesome and expensive,
on account of being carried on below water level, and through a
thick stratum of loose earth and gravel. Very little of the coal
hitherto obtained has been of merchantable quality.

Written Communications.—A letter was read from Dr. J.
P. Giraud, presenting the copy of his work noticed in the
donations of this evening.

Versat Communications.—Mr. Quinby communicated some
facts in relation to the Spontaneous Combustion of bituminous
coal.

He had recently conversed with a gentleman who arrived on
Friday last, in Philadelphia, from South America. The steam
vessels sent from England to the Pacific, to run between Valparaiso
and Panama, were made the subject of remark. His informant
stated that one of the cargoes of coal sent from Great Britain to
Chili, for the use of the steamers, took fire spontaneously on the
voyage round Cape Horn; and that it was with difficulty extin-
guished. The gentleman also alluded to the fact so well known on
that coast, that cargoes of bituminous coal, obtained at Conception,
a few degrees south of Valparaiso, had ignited spontaneously on
the voyage to Coquimbo, in the north of Chili, where an extensive
copper-smelting establishment had been projected by an English
company, and which was abandoned mainly in consequence of the
character of the Conception coal.

Dr. Morton stated, that he had in his possession a living
albino Raccoon, Procyon toror, which he had received from
the Rev. Joseph B. Gross, of Saillersville, near Easton, Penn-
sylvania. The animal is remarkably large and healthy, with
very long yellowish white fur and pink-coloured eyes. Both
in appearance and habits, this individual has much resem-
blance to a bear, and forcibly reminds the observer of the fact
that Linnseus placed the Raccoon in his genus Ursus.

Prof. Johnson exhibited an apparatus to illustrate the pheno-
mena of the rotation of fluids.

A cylindrical vessel or jar, about 4 inches in diameter and 12
inches high, was placed on a stand supported on an axis of revolu-
tion, standing vertical on a pivot, and put in motion by a band from
a larger wheel moved by a crank. When any liquid is placed in

122 [Novemser, 1841.

this jar and a rapid motion is given te the latter, the liquid by
degrees acquires the rotary velocity, and by the effect of centrifu-
gal force is compelled to rise round the inside of the jar. If the
velocity be sufficient, the liquid may be made to rise to the very
top of the jar and be thrown out.

If two liquids of different specific gravities and incapable of
chemical action on each other, be placed within the jar, the rota-
tion of the glass may give to the different liquids corresponding
velocities of rotation, but these will be acquired in times varying
with the adhesiveness of the liquid to the glass.

This diversity in the times of acquiring the same velocity as the
containing vessel, gives rise to some apparent anomalies, while the
speed is either increasing or diminishing. If oil and spirit of tur-
pentine be placed in the cylinder, the former at the bottom, the
surface of separation is more concave upward than the upper surface
of the turpentine, because the oil is more adhesive than the spirits
of turpentine: but placing alcohol below the spirits of turpentine,
the latter becomes the more adhesive liquid and acquires the velo-
city of revolution of the jar sooner than the other, whence it will,
by its superior centrifugal force, be urged downward as well a
upward, from its original level while at rest. ‘The more adhesive
liquid in this case constitutes a double concave lens. The same is
produced when water, oil and alcohol are made to revolve in the
same jar, the oil occupying the middle stratum in a state of rest,
forms, at first and while the velocity is increasing, a concave sur-
face both above and below, but when the speed of the revolution of
the jar is slackened, it is by its superior adhesiveness sooner brought
to rest than the other two liquids; these will therefore, by con-
tinuing their centrifugal force after that of the oil has ceased, cause
the latter to assume a double convex form.

Prof. Johnson referred to some statements relative to experiments
of this nature sometime since made in Paris, in which it was de-
clared, that the “‘ chemical affinities” of the liquids were the cause
of these apparent anomalies ; and that attempts had been made to
deduce from experiments of this nature “a mechanical measure of
chemical affinity.” With that species of attraction he proved that
the results could have no connexion.

extract from another to him from Capt. Land, presenting the
Academy with the complete skeleton and skin of the Orang of
Borneo, Simia satyrus? received November 2d.

Dr. George C. Leib communicated a description of the nest
and eggs of the Fulica Americana and Anas discors.

He saw the Fulica Americana, in the month of June, 1841,
breeding in the greatest abundance in the marshes bordering on
Lake Erie, Erie county, Michigan. They were associated with the
Florida galinules (Galinula galiata,) which were likewise em-
ployed in the labour of reproduction, and so close was the intimacy
between them, that their nests were interspersed over the marsh
in the most neighbourly contiguity, seldom being more than a few
feet apart. ‘The nest, rounded in form and rude in structure, is
composed entirely of dried or withered rushes, without lining of any
sort, slightly interlaced, except at bottom, where there is a simple
crossing of the pieces to the depth of several inches.

It is five inches in depth, by a foot anda half to two feet in
diameter. This large mass is placed on the surface of the water
among the dense rushes, to which it is attached in several points of
its circumference, thus rendering it less liable to be swept off by the
winds and waves.

When disturbed these birds emit a note not unlike the cackle of
the domestic hen, which is transmitted from one to the other fora
considerable distance around, till the air becomes vocal with their
music. This was heard by Dr. Leib not only during the day, but
also at all hours of the night.

The number of the eggs varies from ten to fifteen, though the
latter were observed to prevail. They are of an oval form, and
measure two inches by one inch and a quarter, uniformly sprinkled
with small dark brown spots on a greenish yellow ground. Both
male and female assist in incubation.

Owing to their exceeding abundance, they are gathered by the
neighbouring farmers for the table, and are considered by them
superior in flavour and delicacy to the common hen’s egg.

Novemser, 1841.] 125

Dr. Leib found the nest of the blue-winged Teal (Anas discors,)
together with that of the Mallard (Anas boschas,) in the month of
June, in the meadows adjoining the marsh above referred to.

It is composed externally of dried grasses, neatly arranged in a
circular form, and lined with a thick bed of down, taken from the
breast of the female. It contained 18 eggs of a delicate cream
colour, which measure 2 inches by 14 inch. Though remarkably
timid and wary at other times, such is 197ml traction or devotion
when upon the nest, that it would suffer me to approach near enough
to strike it with a stick ; then in the greatest alarm, suddenly flutter
and bustle off through the grass for some distance, like a wounded
bird ; until, satisfied that the ruse had diverted attention from its
treasure, it would mount into the air and quickly leave the object
of its terror and solicitude behind.

Dr. Morton made some remarks on the so called Pigmy race
of people who are asserted to have formerly inhabited a part
of the Valley of the Mississippi.

It has long been contended by intelligent persons, who, however,
were ignorant of anatomy, that the adjusted bones of individuals of
this race, never exceed four feet and a half in height, and are
often but three feet. These statements induced Dr. Morton to inves-
tigate the subject by means of a skeleton of one of these people,
which he at length obtained through the kindness of Dr. Troost of
Nashville ; Mr. A. M‘Call, a correspondent of Dr. Troost, having
exhumed these remains from a cemetery near the Cumberland
Mountain, in White county, Tennessee.

“The coffins,” observes Mr. M‘Call, in the letter read by Dr.
Morton, “are from 18 to 24 inches in length, by 18 inches deep
and 15 wide. They are made of six pieces of undressed sandstone
or limestone, in which the bodies are placed with their shoulders
and head elevated against the eastern end, and the knees raised
towards the face, so as to put the corpse in a reclined or sitting pos-
ture. The right arm rested on an eathern pot, of about two pints
in capacity, without legs, but with lateral projections for being lifted.
With these pots, in some graves, are found basins and trays also of

19

126 [Novemser, 1841-

pipe clay and comminuted shells mixed ; and no one of these reposi-
tories is without cooking utensils. In one of the graves was found
a complete skull, and an os femoris, but most of the other bones
were broken in hastily removing them. This is said to be the lar-
gest skeleton ever found at any of these burying grounds. It has
the cranium very flat and broad, with very projecting front teeth,
and appears to have pertained to an individual not over twelve or
fourteen years of age.”

After reading Mr. M‘Call’s letter, Dr. Morton exhibited the
bones which accompanied it, and remarked that the stage of devel-
opment of the teeth indicated a very juvenile subject. For example,
many of the deciduous or first teeth yet remained in both jaws;
while the only teeth of the permanent set which had protruded, were
the first molars and the incisors, which, as every anatomist knows,
make their appearance at about seven years of age. Of the other
permanent teeth, some had no part formed but the crown, and all
were completely embraced within the maxillary bones. The pre-
sence of the new incisors, isolated from the cuspidati which had not
appeared, obviously gave rise to Mr. M‘Call’s remark respecting
the very “ projecting front teeth,” but which, however, are perfectly
natural in position and proportion. The cranial bones are thin, and
readily separable at the sutures ; nor does the flat and broad confi-
guration of the cranium differ from what is common to the aborigi-
nal American race. The long bones have their extremities sepa-
rated by ephiphyses; and every fact observed in these remains is
strictly characteristic of early childhood; or about the seventh
year of life. Even the recumbent or sitting posture in which
they are found, has been observed in the dead bodies of the
American nations from Cape Horn to Canada; and the utensils
found with them, are the same in form and composition with
those exhumed from the graves of the common Indians.

Dr. Morton concluded by remarking that these remains were to
him an additional and convincing proof of what he had never doubt-
ed—viz. that the so called Pigmies of the western country, were
merely children, who, for reasons not readily explained, but which
actuate some religious communities of our own time, were buried
apart from the adult people of their tribe.

Written Communications.—Mr. 8.8. Haldeman submitted
a note on a genus of Dolphins. He proposes the name
Hypodon for those dolphins which have two teeth in the lower
jaw, hitherto constituting the genus Diodon; which name, how-
ever, is preoccupied for a well known genus of fishes. The
name may be thought too much like Hyperodon; but this is an
advantage, as the two are taken from similar characters ;
Hypodon meaning teeth below; the other, teeth above. Ex-
amples, H. Desmarestii—H. Sowerbyi.

Versat Communications.—Prof. Johnson exhibited and ex-
plained his apparatus, illustrative of the laws of chemical
combination and of the combining volumes of gaseous sub-
stances.

This apparatus consists of a series of cubical types, each of such
magnitude as to represent by its bulk in cubic inches the atomic
weight of one of the elementary bodies. Thus hydrogen is represent-
ed by a cube one inch on a side ; oxygen, by a cube of two inches
on a side, containing of course eight cubic inches; iron by a cube
containing twenty-eight cubic inches, and so of the whole fifty-four

128 3 [Novemper, 1841.

simple bodies. The largest cube representing Uranium is a little
more than six inches on a side. Each cube bears on one of its
faces the conventional chemical symbol of the body whose atomic
weight it represents, usually the first letter of its name, together
with the number expressing its atomic weight. Many of the
types are coloured either by a coating of the material represented,
or by some convenient pigment exhibiting the natural appearance
of the body represented. The number of types of each body
varies with the complexity of the compounds into which it is capa-
ble of entering ; the greatest number being required of those bodies,
which constitute organic substances, viz. carbon, hydrogen, oxygen
and nitrogen.

A second part of the apparatus consists of a light frame support-
ing three shelves about fourteen inches apart, open both at the
front and rear. This frame is four feet long and two and a half feet
high. In order to represent chemical combinations and decomposi-
tions, the atom-cubes are first placed separately upon the middle
shelf, to represent tie case of solution or the liquid state. They
are then brought together to indicate mixture of solutions. To
represent precipitation, those atoms which are in fact precipitated
in actual solutions are carried to the lower shelf; and to represent
the products converted into gas, those atoms which constitute such
products are carried from the middle to the upper shelf.

The chemist performs the processes first in his jars or retorts,
and then arranges the atoms to indicate the real operations which
have been taking place before the eyes of his class.

In exhibiting the combinations of bodies which may assume a
gaseous form, Prof. Johnson makes use of a third apparatus, con-
sisting of glass cubical boxes of 100 cubic inches each, and of others
containing 50 and 164 cubic inches.

‘To represent the combinations and decompositions of gases as in
experiments in Eudiometry, both the cubical types and glass boxes
are brought into requisition. ‘Thus the type of hydrogen (a cube
one inch on a side, marked H—1,) is placed on the upper shelf, and
over it is inverted a cubical glass box, marked 100, and actually
containing that number of cubic inches; an oxygen type (marked

U—S) is placed separately on the same shelf under a glass box of
the same size as to base, but of only half the height of the former,
and containing of course 50 cubic inches. To represent the com-
bination of these ‘gases to form water and to indicate the amount of
condensation which takes place, the oxygen type is taken from
under its own box and placed with the hydrogen type beneath the
glass box of 100 cubic inches, the 50 inch box being at the same
time removed from the frame. ‘There is then seen the sum of the
weights of the constituents of water (9), and the bulk of the vapour
of water, the same as that of the hydrogen which had entered into
its composition. To convey the impression that the product is a
liquid, the resulting combination of atoms is carried from the upper
to the middle shelf, without being accompanied by the volume-cube.

The advantages found to result from this method of illustration
over those hitherto in use were stated to be the saving of much
time and labour, in writing out diagrams and making drawings,
and the avoiding of inconvenience of working at a black-board to
give after all but an imperfect impression of the truth to be con-
veyed. An effect of not less importance was derived from appeal-
ing to different faculties at the same time.

To some minds the bulk of a body conveys a far more distinct
impression of its weight than the figures which represent that
weight. In the method now exhibited, both these modes of appeal-
ing to the mind and memory are united. The colour of many of
the substances combined with the bulk—with the symbols which
represent them and with the figures which express their weight, can
hardly fail to fix a lasting impression on the mind of every student
in chemistry. To these may be added the facility of making appa-
rent by direct juxtaposition the relation by weight and by volume
of the constituents of all gaseous mixtures.

The application of this apparatus was shown in exhibiting the
composition of the oxides and other minerals.

The views of M. Liebig in regard to the composition and true
radical of Phosgene gas, carbonic acid and oxalic acid, were also
displayed.

The constitution of ammonia, of atmospheric air, of nitrous

20

130 [Novemser, 1841.

oxide, and binoxide of nitrogen, was illustrated both in regard to
atomic weight and combining volume, as were the several com-
pounds of chlorine with oxygen. The acetate of lead was decom-
posed by a solution of hydrosulphate of ammonia, and the res ing
acetate of ammonia, sulphuret of lead and am atom of watér werd
indicated as the results.

Chloride of iron precipitated by carbonate of ammonia, exhibited
the effects of giving a precepitate of oxide of iron and evolving
carbonic acid, decomposing water instead of forming it as in the
preceding example.

Pinna.

P. rostriformis.—Shell thin, elongated, narrow, smooth, but
gently undulated from the beak to the opposite extremity.
This fossil is not uncommon in fragments in the cretaceous

limestone of Timber Creek, in Gloucester county, New Jersey ;
but this instance is the first which has occurred sufficiently
perfect for description. Ihave referred to it in my “ Synopsis
of Organic Remains,” page 63, but did not then venture to give
it a specific designation. The specimen now in question was
found and kindly lent me by Mr. Conrad.

sub-conical. Scutellz in pairs? separated by longitudinal,

granulated, slightly curved bands. Spines elongated, lon-

gitudinally granulated, and attached to the papille by

numerous very small, flattened appendages.

Found with the preceding fossil in the cretaceous limestone
of New Jersey.

A communication was read from Oliver P. Hubbard, Esq.,
acknowledging the receipt of a letter announcing his elec-
tion as a correspondent of the Academy.

Mr. John 8. Phillips stated that the Helix described by him
at page 27 of these Proceedings, with the specific name of
bidentifera, is the H. barbula of Rossmasler,a Portuguese shell.
Mr. P. was led into an error in respect to its locality by the
gentleman from whom he received it, and consequently de-
scribed it as new.

Dr. Morton communicated the results of the measurements
of forty-five adult negro crania, in order to ascertain the in-
ternal capacity of the skull and consequent size of the brain
in the African race. These skulls were those of negroes born
in Africa, of the Bassa, Grabbo, Makoua, Benguela, Mina and
other tribes. ‘They consist of 25 males and 20 females, vary-
ing from 18 to 50 years of age. The largest heads in the
series, three in number, give ninety-nine cubic inches of inter-
nal capacity ; the smallest head, that of a Makoua, 68 cubic
inches. The mean of the whole series gave eighty-five cubic
inches.

Dr. Morton added, that he was not yet prepared to give a
decided opinion in relation to the comparative size of the
European and Negro brains, but so far as his observations had
gone, he believed the former would be found to exceed the
latter by at least seven cubic inches.

The measurements adverted to give the absolute size of the
brain, and were conducted on the plan described at page 7 of
these Proceedings.

STATED MEETING, Decemeer 21, 1841.

Viczr Prestpent Morton in the Chair.

Warurren Coumunications.—A letter was read from the
Rev. William Coggswell, corresponding Secretary of the
Northern Academy of Arts and Sciences, at Hanover, New
Hampshire, soliciting for that Institution a portion of the pub-
lished transactions of this Society. Whereupon the committee

136 [Decemper, 1841.

of publication were instructed to furnish Dr. Coggswell with
volumes VI. and VII., and Part I. of Vol. VIII., together with
the Proceedings of the Academy as far as published.

A letter was also read from Dr. Edwin Fussell, dated Pen-
dleton, Indiana, December 5th, announcing that he had trans-
mitted a box of Fossil Organic remains for the cabinet of the
Academy, and tendering his services in collecting in several
other departments of Natural History.

The chairman then called the attention of the members to
the importance of publishing, without delay, and in accordance
with a former resolution, the second part of volume VIIL. of the
Journal of the Academy. He stated that several highly im-
portant memoirs awaited the Society’s acceptance, which
together with those already in the hands of the committee,
were amply sufficient to form a half volume.

Verpsat Communications.—Dr. G. C. Leib remarked, that
in looking over Dr. Giraud’s work entitled “Sixteen New
Species of Birds,” he found the Parus leucotis of Giraud, to
be identical with the Setofaga rubra of Swainson.

Professor Johnson made some observations on the sponta-
neous combustion of Bituminous Coal.

He stated that he hadrecently been invited to inspect a heap of bi-
tuminous coal on the premises of Mr. John W. Middleton of this city,
which had for a few days previous been observed to be growing ‘warm
and giving off vapour very copiously ; from which it was inferred to
be approaching spontaneous combustion. The coal in question
was stated to be from the Allegheny mountain, above Hollidays-
burg,and to be a mixture of two or three different mines. On
causing a hole to be excavated about three feet deep, the tem-
perature was found to be 110 Farenheit ; and the day being cold,
(below freezing point) the volume of steam which arose on moving
the coal was so great as almost completely to envelope and hide the
workmen. All parts of the heap were observed to exhibit distinct
traces of the effloresced sulphate of iron; or if some pieces of the
coal had no visible marks of this kind, they still exhibited to the
sense of taste the strongest evidence of being covered with that
salt.

This coal evidently possessed all the requisites for producing
spontaneous combustion, and only required time, and perhaps a
rather larger heap, to bring that process to the same termination as
was observed a few weeks since in the city of Lowell.

The chairman having announced the demise of our vener-
able associate John Vaughan, Esq., on motion of Professor
Johnson, it was unanimously

Resolved,—That this Society have heard with deep regret, the
announcement of the decease of their late valued member, John
Vaughan, Esq.,—so long known in our community for his various
merits, both in relation to scientific objects and to benevolent pur-
poses and institutions; and they would by this act testify their

high estimation of those excellent traits of character by which
their deceased fellow member was so eminently distinguished.

Resolved,—That the Corresponding Secretary communicate to
the family of the deceased, a copy of the foregoing resolution.

Two specimens of the Fuligula minor (Giraud), or Scaup

Duck. Presented by Mr. J. G. Bell, of New York.

Waraitten Communications.—A communication was read
from Mr. Haldeman, describing two new species of the genus
Perca, from the Susquehanna river, viz., P. nebulosa, and P.
minima; which was referred to a committee.

A letter was read from Mr. J. G. Bell, of New York, dated
January 8th, in which he offers some remarks on the two
specimens of Fuligula minor, or lesser Scaup Duck, presented
by him this evening. He states, that they have hitherto been
mistaken for the common Scaup Duck, Anas marila of Wil-
son; and although Mr. Audubon figures this bird, and Wilson
the larger one, these naturalists had supposed them to be spe-

142 (January, 1842.

cifically the same. He adds, that Mr. Audubon has now com-
pared these two ducks, and is satisfied that they are distinct
species.

Mr. T. A. Conrad read a paper intended for publication in
the Journal, entitled, “ Observations on the Silurian and
Devonian systems of the United States, with descriptions of
New Organic Remains.” This memoir embraces descrip-
tions of 103 new species, included in 21 genera, viz.

“Avicula—23 species. Cypricardita, 6. Inocramus, 3.
Microdon, 1. Moculites, 2. Plurorynchus, 3. Strophomena,
21. Delthyris, 13. Orthis, 1. Atrypa, 6. Hlelicoceras, 1.
Orthoceras, 1. Goniotites, 1. Belerophon, 3. Pleuratoma-
ria, 7. Euomphalus, 1. Loxonema, 1. Cyrtoceras, 1. Asa-
phus, 2. Calymene, 1.

The paper was referred to a committee with a view to
immediate publication in the 2d part of the 8th volume of
the Academy’s Journal, now in press.

Professor Rogers announced that his brother Professor William
B. Rogers, of Virginia, had recently satisfied himselfof the geological
age of the coal formation of the vicinity of Richmond; and also of the
date of the Fredericksburg sandstone. The former he regards as
nearly equivalent in period to the lias of Europe, and the latter to be
referable to that of the oolite. The existence in the Richmond coal
measures of the genus Teniopterus, a race of plants strikingly charac-
teristic of the lias, is one of the points upon which he rests his con-
clusions respecting that formation. A discovery in the Fredericks-
burg sandstone of fossil cycadez and other organic remains, lead him
to place this rock in the period of the oolites. He considers those the
only formations yet recognised in the United States, which are
referable to the ages of the European Lias and Oolite rocks.

Warirren Communications.—Mr. Haldeman read a paper on
three new species of Unionide, from the waters of the United
States, viz. Unio abacus, U. purniceus, and Anodon plicatus.
Referred to a committee.

Mr. Conrad read some additions to his paper on the Silu-
rian and Devonian Fossils read at the last meeting ; which was
referred to a committee.

Mr. Conrad also read a memoir, “ On the Identity of the
Middle Cretaceous Formation of the United States, with the
Faxoe limestone of Europe.”

Mr. Conrad stated as the result of mature observation and reflec-
tion, that the medial division of the American cretaceous strata, as
seen on Timber creek, in New Jersey, are of the same age with the

144 [January, 1842.

white chalk of Europe, as maintained by Dr. Morton. He announ-
ced the discovery at that locality, of a Planularia, a multilocular
shell characteristic of the European chalk. Mr. Conrad has also
detected in the medial cretaceous beds at Wilmington, North Car-
olina, the Cirrus perspectivus, a Nautilus which he believes to be
the N. Danicus, and the Cyprza bullaria ; the last two being cha-
racteristic of the Faxoe limestone.

Mr. Conrad’s paper being designed for publication, was
referred to a committee.

Verzat Communications.—Professor Johnson stated the re-
sults of some experiments on the magnetism of bars of wrought
iron broken by tensile force.

He referred to a former communication, in which he had given
an account of trials on cast iron in a state of fusion, and to the influ-
ence of terrestrial magnetism, inducing the magnetic state in bars
of iron, according to the position in which they are placed with
reference to the magnetic axis. He had found that when a bar of
soft iron is drawn asunder at ordinary temperatures, and in the
direction of the magnetic meridian, there was always manifested at
the point of fracture a decided evidence of magnetic polarity ; and
that the kind of magnetism was that belonging to the region to-
wards which the broken extremity of each fragment pointed. ‘This
magnetic condition was indicated by the adhesion of any particle of
iron or of hammer cinder, which chanced to be near the fracture at
the moment, as well as by the action of a small needle when held
near the point.

If the two extremities separated from each other by a short
distance, be at the moment of fracture in contact with a mass of
iron filings, the latter will adhere to the two ends, and extending
across, form a continuous line or bridge, which appears to serve as
a keeper, for they continue for a considerable time with little dimi-
nution of their force.

When the fracture is made at a red heat, little or no magnetic
effect appears to result from the action of breaking. But when

January, 1842. | 145

the temperature of the bar is between five and six hundred degrees
of Farenheit, the magnetism is not only marked at the time, but
is in a great degree permanent. Samples were stated to have been
examined, which had been broken for several years, and to be still
in the same magnetic state in which they were at the moment of
fracture.

In order to prove what part of the effect in the foregoing in-
stances, was due to the earth’s magnetic influence, the proving
machine which produced the fracture, was changed in position, so
as to place the bar, in proving, directly across the magnetic meri-
dian, instead of coinciding with it as before. In this case no polarity
was observed, whether the bars were broken cold or hot, except
some slight indications in a direction across the breadth of the bar
at the point of fracture.

balance of the late Wm. Maclure’s subscription to the Aca-
demy, amounting to $6000. had been received from his brother
and executor, Alexander Maclure, and that the same had
been appropriated to the payment of various claims on the
Institution, the details of which were given.

Whereupon the following resolutions, offered by Prof. John-
son, were unanimously adopted :

Resolved,—That the Academy has received with lively
satisfaction the announcement this evening made by the
Treasurer, of the receipt of $6000, on account of the second
subscription of $10,000 by our late President, William Ma-
clure, Esq., deceased, towards the erection of the new Hall;
and of its application to the final extinguishment of claims
on account of the building, and to an important reduction in
the obligations for the purchase of the ground now the pro-
perty of the Institution.

Resolved,—That the thanks of the Academy are due to
Alexander and Anna Maclure, executors of the will of their
late brother William Maclure, for their praiseworthy efforts in
carrying out the designs of the deceased, in advancing the
interests and prosperity of this Institution, and thereby pro-
moting the cause of Science, to which so much of his liberal-
ity, and so large a portion of his life, were devoted.

On motion of Mr. Clay, Resolved, that a copy of the fore-
going resolutions be transmitted to Alexander Maclure, Esq.

BUSINESS BY SPECIAL KkESOLUTION,

The chairman called the attention of the Society to several
papers on scientific subjects, offered at previous meetings,
which had not been referred to appropriate committees, and
suggested some action thereon.

On motion of Dr. Elwyn, the subject was then bronght
before the meeting, and the communications alluded to were
referred, as follows:

A paper by Walter R. Johnson, “On the relation between
the coal of South Wales and some Pennsylvania anthracites,”’
read June 15,1841; and another by the same author, entitled,
‘¢ Description of an apparatus illustrative of the laws of chemi-
cal combination, and of the combining volumes of gaseous
substances,” read Nov. 23d, 1841: referred to Messrs. Dra-
per, Lukens and Phillips.

Written Communicarions.—-The chairman read a memoir
from Dr. A. Clapp of New Albany, Indiana, on the Lime-
stone formation of that district. Referred to a committee con-
sisting of Mr. Conrad, Prof. Rogers and Mr. Vanuxem.

VersBaL Communicarions.—Prof. Johnson presented for
inspection, a portion of the kelson of the frigate Raritan, in a
state of dry rot. This vessel was still on the stocks at the
Philadelphia Navy Yard:her building having been commenced
at least 20 years since. She had been salted. Her lower
timbers, previous to the commencement of repairs, were
generally in the same condition as the portion exhibited.

Also a sample of oak joist from the old Legislative Hall,
built at Chester, Pennsylvania, in 1682. Decay had not yet
commenced in this wood, owing probably to its complete pro-
tection from the action of moisture ; whereas in the other case,
the wood was constantly subjected to the alternate action of
dryness and moisture.

Professor Johnson also alluded to the hardening influence
of water on oak wood when long submerged.

Dr. Chaloner stated that he had in his possession specimens
of oak timber turned into various forms, which had been
derived from a vessel, (the Lyons frigate,) submerged in the
river Delaware since the period of the Revolution, and which
had acquired almost the hardness of iron.

Professor Johnson then exhibited samples of residua from
24

156 [Marcu, 1842.

a number of Anthracite and Bituminous coal of Europe and
this country, on which he had experimented with a view of
ascertaining the relative proportions in each, of volatile mat-
ter, earthy matter, and carbon. The experiments were per-
formed on all in a similar manner, viz. by exposing the coal
to a red heat, raised as rapidly as possible. As the moisture,
however, is in such cases brought in contact with carbon at
a high temperature, it may, by decomposition, cause some of
the carbon to be carried off, and thus raise the estimate of the
volatile matter above what it would be, if more slowly con-
ducted. Incineration was conducted in a muffle, at a high
and long continued temperature.

The following are the results of the analysis of some of
these coals :

Vol. matter. Ashes. Carbon.

Dr. Chaloner referred to the question agitated of late
among medical men, whether muscular action could excite
electricity, and cited the case of a lady, described in Silli-
man’s Journal; a similar instance had come under his own
notice in this city.

Marcu, 1842.] 157

As connected with this subject, Professor Johnson mentioned
that some years since, he had made experiments with a deli-
cate magnet, in suspension, and discovered that by bringing
the hands nearly in contact with each other, and then care-
fully withdrawing them in opposite directions, the fingers of
the different hands, when approximated to the magnet, pro-
duced different effects.

BUSINESS BY SPECIAL RESOLUTION.

By special permission, the reports of the following com-
mittees were read and adopted.

The report of the committee on Dr. Morton’s paper on the
so-called Pigmy race of the Valley of the Mississippi, and also
his paper on the ancient Peruvian race: in favour of publica-
tion.

The report of the committee on Prof. Johnson’s paper enti-
tled “Remarks onthe relation between the Coal of South
Wales and some Pennsylvania Anthracites;’’ and also his
“ Description of anapparatus illustrative of the laws of Che-
mical combination, and of the combining volumes of gaseous
substances ;”’ in favour of publication.

Dr. Elwyn offered the following resolution, which was
adopted :

Resolved,—That the Commiitee of Publication be authorised

to present to Charles Lyell, Esq., Corresponding member, the

had successfully repeated an improvement in M. Daguerre’s
process, by which an instantaneous impression of the object
may be taken ; consisting in applying aspark of electricity to
the back of the plate. The positive spark appeared to be more
effectual than the negative.

MEETING FOR BUSINESS, Maxcs, 2978, 1842.

Vice PrestipeEntT Morton in the Chair.

The Monthly Report of the Corresponding Secretary having
been read and adopted, reports were presented from the fol-
lowing committees.

The committee on Dr. George C. Leib’s paper entitled,
«Description of the Nest and Eggs of the Fulica Americana
and Anas discors,”’ in favour of publication.

The committee on Mr. Haldeman’s paper “On two new
species of Cyclops;”’ in favour of publication.

The committee on the several papers of Mr. Audubon and
Dr. Bachman, entitled “‘ Descriptions of new species of North
American Quadrupeds;” in favour of publication.

The Zoological Committee then read the following Report
in relation to the condition of the collection of Insects lately
returned by Dr. T. W. Harris; which was ordered to be pub-
lished in the Proceedings of the Academy.

The Zoological Committee report, that they have examined
the collection of insects belonging to the Academy, which

Marcu, 1842. ] 161

was sent to Dr. T. W. Harris, of Cambridge, Mass., in the
year 1837, for the purpose of being re-arranged, determined,
and having the specimens of Mr. Thomas Say intercalated in
their appropriate places, and find that the insects have been
returned in so confused and ruined a condition as to render
them almost valueless; that there is not a single insect
determined, except those by Dr. McMurtrie prior to the col-
lection having been sent to Dr. Harris, and that the species
in Mr. Say’s collection have been in no instance intercalated ,

They further report, that as the greatest care was taken in
the carriage of the cases from the vessel to the Hall of the
Academy, on hand-barrows, the specimens could have sus-
tained no injury subsequent to their arrival in Philadelphia.

The committee cannot refrain from expressing their regret
that if Dr. Harris, for whatever cause, declined the fulfilment
of his engagement to the Academy with respect to this col-
lection, that he did not at once return it, in order that it might
receive such attention as would have secured its value unim-
paired ; especially since he was duly notified of various reso-

lutions and inquiries, expressive of the anxiety felt for its safe
return.

ings of the Academy.

Description of two new species of Cypris, and a genus of
Sterelmintha presumed to be new. By S. 8. Haldeman,
Read March 22, 1842.

Cypris discolor. Elevated, base nearly straight, equally rounded at both ends:
an irregular mottling of blackish immediately behind the eye; a rather smaller
blotch of reddish brown at the anterior extremity, and a large one of the same
color at the posterior extremity, occupying about one-fifth of the entire surface.

Variety. The central spot is sometimes reddish, and the posterior one divided
into two. Length 0.5 millim.; heighth compared with the length, as 5 to 7.
Hab.: in great abundance, a log-pond at the mouth of the Chicquesalunga, on
the Susquehanna.

Cypris vitrea. Translucent, with a tinge of yellow, elongated, nearly straight
both ends nearly alike, but the posterior slope is somewhat flattened: about one
third of the heighth and length along the dorsal margin, is stained light green:
eye obsolete: length 0.5 millim. Hab. : with the preceding, but is comparatively
rare. Rather more slender than C. simplex, Hald.

Hydrolimax. Body slender, limaciform, parenchymatous, provided with vibrile

cilia) without tentacles or eyes, a posterior nucous pore? mouth subterminal,

bellshaped when expanded. Lives upon mud at the bottom of quiet water: pro-
gression as in Limax.

Hydr. grisea. Half an inch long, mottled grey above; colorless below, and
upon each side of the anterior extremity, where the grey of the back is suddenly
narrowed. Hab. : with the preceding species. Bears a striking resemblance to
a large grey Limax (L. togata, Gould), found in Pennsylvania and Virginia.

WRITTEN COMMUNICATIONS.

_ Letters were read—

g
From Mr. William Vaughan, dated London, March 5,
1842, stating that he had transmitted a parcelto the Academy,
from the Linnean Society of London :

From M. de Longchamps, dated Liege, April 15th, 1841, in
relation to the books presented this evening; and also express-
ing a wish to obtain Part. I. of Vol. VIII. of the Journal of the
Academy. A list was likewise given of various insects and
animals, which he was desirous of exchanging for similar ob-
jects of this country :

And from George R. Gliddon, Esq. dated New York, April
24, 1842, stating that he has presented to the Academy a col-
lection of Geological and other specimens from Egypt: and
also acknowledging the receipt of his notice of the election as
Correspondent of the Academy.

VERBAL COMMUNICATIONS.

Dr. Chaloner stated, that he had been informed by a gen-
tleman from Washington county, Pennsylvania, who had re-
cently returned from Central America, and had there met
with Messrs. Stevens and Catherwood, that these latter had
discovered the remains of another city, covering an area of
about six miles square.

The ruins were in a good state of preservation; and some
specimens of sculpture brought thence by him, evince marks
of much skill and beauty.

The beam of wood referred to in Stevens’s Central America,
and found in the ruins of Uxmal, was stated to be well pre-
served. The tree from which the wood is derived, is called
by the natives Zapadillo. It is more durable than live oak
or red cedar, sinks in water,and when polished, resembles
« Partridge wood,’ but is darker and harder.

Dr. Chaloner made inquiry with regard to some Infusoria
said to have been discovered in the green sediment of pools ;
and which are stated to possess the peculiar property of evolv-
ing oxygen gas under the influence of the sun’s rays.

When examined by the microscope, they rose to the sur-
face, emitted a bubble of gas and then subsided. This gas,
collected in an inverted jar, was found on analysis to yield
about 80 per cent. of oxygen.

Dr. B. H. Coates then made some remarks on the progress
of discovery in relation to this class of animals; and called the
attention of the members to the late work of Mr. Pritchard,

and communicated some of the information which he had
derived from this author.

Dr. Bridges remarked that, in relation to the first mentioned
discovery, in the absence of more definite information, the
facts which had been communicated would lead us to suppose
that the subjects of observation were of a vegetable nature ;
since it is well known that vegetables under the influence of
the sun’s rays, evolve oxygen by the decomposition of car-
bonic acid, which is always present in the atmosphere and in
water. He also alluded to the difficulty of discrimination
between animal and vegetable bodies, especially in micros-
copic objects, and made reference to a paper on the Sponge,
in one of the late numbers of the Transactions of the Linnean

Society, to illustrate the great accuracy of observation re-
quired in these cases.

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 Coniferz, and observed that most of those on the table
evidently possessed this character; others however belonged
to the Endogene.

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 thestone. 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,

Resolved,—That a Committee of three be appointed to

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

MEETING FOR BUSINESS, May 31, 1842.

Vice Prestpent 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. 8S. 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 the 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 tke authorship of a book in which he finds and corrects grammatical errors.
Admit the principal that Unio metanevra, Raf. 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 bave been described here as masculine ; and any one not a botanist, may
place the species of Potamogeton (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 Unionide, I wish to propose
a few corrections in nomenclature, before they are made, and the species appro-
priated abroad, by some one who will not cite the original describer. A western con-
chologist gives all the species of Alasmodon to Mr. Lea, not because he was the
first to name them, to create the genus, 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, 1842.] . oe

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. ‘Che same principle would deprive Mr. Lea of all his spe-
cies of Alasmodon ; for assuredly authors will not adopt Shumacher’s name for
this genus, when so much a better one is in general use. (ceneric 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 Ornithocephalus; it is now called Pterodictylus. 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.

T’o put these matters to the test, I propose that the letter w shall take the place
of w 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 Couperzi be adopted instead of the above. There is an “ Anodonta
Cowperiana” which I do not correct, because I wish merely to discnss a princi-
ple. I propose that all the species of the genus Alasmodont 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 propositions, 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, 1842, 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
25th, 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 there appears to be little or no true carboniferous lime-
stone east of the Falls of the Ohio. ‘he stratum which he doubifully referred to
it, in a previous letter of December, 1840, viz the Oolitic and Pentremite 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 [ndiana, part of Kentucky and Illinois. It
is entirely wanting in Ohio. ;

He refers to bis 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 Silarian 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 Wenlock limestone, but the

*The midile 4 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 Riyn-
chops, entitled to these genera, with their species? In a notice of Kiener’s work,
in the Revu: Zoologique, this author is censured for writing “ Pleurotunia mitra,
formis, Vul,’ Wood baving previously used the specific name “ mitr/formis.”

F + This is the more correct form, and corresponds with Mouodon, Hyodon, Dio-
on, etc.

178 [ May, 1842.

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 fcetid limestone eight feet thick,
containing Encrini, a Conularia, Delthyris and Favosites, and a few other co-
rals, and immediately underlies the black slate. In must 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 lunata vel reticularis, leptena
lata 2 Turbo carinatus, Terebra sinuosa, Tentaculites, perhaps a new species,
Avicula reticulata, Calymene bufo, Asaphus Micrurus; several undetermined
species of Delthyris, an Eschara, &c.

In the strata below the water-lime were found many fossils of the Wenlock
limestone, Strophomena euglypha, Atrypa prisca, the latter also occurring in
the water-lime and upper limestone; Pleuwrorynchus cureous? of Conrad, and
an immense profusion of Polyparia, characteristic of the Wenlock limestone.

The Catenepora 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-
noida occur, fifty or one hundred feet above the slate; and an Orthis which
Mr. Hall considers identical with a species of the Ludlowville shale of New York.

WRITTEN COMMUNICATIONS.

The Chairman read a letter from Mr. S.S. Haldeman,
dated Marietta, Pennsylvania, May 17, 1842, enclosing com-
munications intended for publication in the Proceedings of
“the Academy, viz: Descriptions of a new species of Cypris, of
two species of Hydrachne, 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 jess than thirty species of animal form ;
including two Crustacea, four Entomostraca, nine Mollusca,
one Annelid, two Hydrachne, and about a dozen aquatic
larve.”’

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 Consheliock-
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 P (Jung, 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 con pressed 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-
zo, 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 dis-
covery of which was due to Professor Horner.

MEETING FOR BUSINESS, June 28th, 1842.

Vice Presipent Morron in the Chair,

The committee, consisting of Mr. Phillips, Dr. Goddard,
and Dr. Morton, to whom were referred the following com-
munications of Mr, Haldeman, reported in favour of publica-
tion in the Proceedings.

Description of two species of Entomostraca and two Hy-
drachne, by S. S. Haldeman.

Darania abrupta. Body short, irregular in outline, back but slightly con-
vex, 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 for-
wards, with a rounded projection opposite the head; ventral margin very con-
vex. Colour, trown; length, 2 millim.

Hab. Ditches along the Susquehanna,

Limnanta coriacea. Body lengthened ; swimming branchie extending along
three-fourths of the inferior surface, from the neck to the extremity of the tail ;
tail crested above with a row of large conical obtuse tubercles; apex of the shell
elevated, and about one-fourth of the length from the anterior extremity ; colour,
light brown; length 5 millim., height 3, diam. 14.

Hab. Ditches along the Susquehanna, in quiet water.

Obs.—The shell is coriaceous and translucent, and bears a slight resemblance
to Mesodesma Jauresii. It is not a little singular that the same generic and
specific name, Limnadia gigas, should have been applied both to a crustacean
and a mollusc, each of which has a bivalve shell, and inhabits fresh water.

Pickering.

VERBAL COMMUNICATIONS.

Professor Jolinson made some remarks on the determination
of copper in analysis. He stated that the usual mode was to
precipitate the protoxide from solution ; that in this case, it is
necessary that an excess of alkali should be added, and the
precipitate well washed. Jt is also attended by a loss in fil-
tering, &c. By using dry sulphate of copper these objections
are obviated. This salt is readily dried without decompost-
tion; and Professor Johnson stated that with the same portion
of copper he repeated 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-

18s {JuLy, 1842.

gy and Botany, it frequently happens that the same name will
occur, not only in both these sciences, but will be occasion-
ally 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
“dpogon are genera in both kingdoms.

{ wish, therefore, to propose a few changes in the names
of several genera, viz :

“Inopaia, instead of Harpyia, Cuv., for a genus of birds, the
latter name being preoccupied, both in Mammalogy and En-
tomology,

Opiacerus instead of Mazama, Smith; this name having
been pre-applied to Ovis or Capra montana, Ord, by Rafin-
esq'ie.

Sargus was long since applied to a genus of dipterous in-
sects by Iliger: Cuvier more recently, upon dismembering
the genus Sparus of Artedi and Linnzus, improperly adopted
it for the typical section, to which, therefore, the original
name Sparus must be applied.

Lynx, (a subgenns of Felis,) was published by Rafinesque
in 1817, and I prliete has the priority of Lynchus, which is
also the name of a genus of Crustacea.

Juty, 1842.] 191

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. Linneus 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 toa genus of
birds. Yet if we turn to the Régne Animal, we will find “:Pogonias, Lacép.”
We do not, however, find Pogonias in Lacépéde, the name being Pogonathus.

I propose Ancyllus and Teronyx, instead of Ancylus and THgpys, for genera
of Hymenoptera.

Conoura, Eucryptus and Auchenella, instead of Conurus, See (Hal.)
and Auchenia, for genera of insects.

Clypastrea and Strongulus, instead of Clypeaster and Strongylus, for coleopte-
Tous 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
distinct genera ; thus Chione, Venilia, Cleodora, Pandora, Hyria, and Lucina,
are commen to Conchology and Entomology ; Sylvia and Tanagra to the latter
and Ornithology ; and Labeo and Zywna to Entomology and Ichthyology.

Dr. B. H. Coates read a “ Note on the Natural Alliances of
the genus Cecidomyia, intended to facilitate identification;’’
which was referred to a committee, viz.: Dr. McMurtrie, Dr.
Pickering, and Mr. Haldeman.

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 pre-
serving and more widely diffusing a memorandum of the alliances of this de-
structive family of insects, s0 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,
ef 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 infflict severe and penetrating
wounds onthe bodies of warm-blooded animals, from the feebleness of its
proboscis. This organ would seem, in general, only fitted for sucking up un-
covered or but slightly covered fluids: and contains, to use the language of one
of the best authorities, only a pair of lancets; being, in this respect, very de-
ficient when compared with the allied family, Culicide. The antenne, with
the exception of a single sub-family, are thread- Eesapett: The perfect insect
shows but little avidity for food.

Five natural groups seem to arise; in each of which the appearance of the

*Cuvier writes “Machera, Lacép.”’ But this genus stands Makaira, in
Lacépéde’s work, and it is more necessary to retain the original orthography,

as Macheera has been recently applied to a genus of Mollusca.

perfect insect visibly differs, and the habits of the larva vary materially in re-
spect to food and habitation. We copy some of the characters.

1. Chirnomices. Aquatic Tipulides. Male antenne plumose; larve aquatic.

2. Tipulides proper. Terrestrial ‘Tipulides. THead elongated into a muzzle’
no ocelli; larvee inhabit the earth.

3. Mycetuprilides. 'Tipulides of fungi. ‘Two or three ocelli; trochanters
elongated ; tibie strongly spurred; larve feed on fungi.

4, Cecidomyides. Tipulides of gall-nuts. Head not prolonged into a muzzle 3
no ocelli; trochanters of ordinary length; antenne moniliform; larve feed on
galls formed on vegetable substances.

5. Bibionides. Tipulides of flowers, Antenne short, perfolint ed, generally
fewer than 12 joints; legs of ordinary length; larve often resident in rotten
dung and vegetable debris. (To me this seems contradictory. ]

The above classification is quoted from M. Latrcille ; and is preferred by the
author whom I have already cited, and whom [ 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 broughtin close approximation some
whose mode of life has subsequently been thought to differ. It has since been
thought to be rendered evident, that the larve 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 Spence.

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 isa genus with terrestrial larve, 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 habits. In the
earlier state of knowledge in relation to the tipulide tribe, and particularly while
the larve were less known, the collocation of several species was doubtful. Mr.
Meigen is said to place the Tipula juniperina, I.., 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-un-
derstood hordes,” or “ unknown, ill-defined group.”

It is observed that every larva of the family, thus far, 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 considera-
tion goes to strengthen, if possible, the inference that the quiescent substance
gnerally supposed, 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 early 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 Chalcidide and Proctotrupide. The
coincidence of these diminutions, from a cause not generally understood, with
various other circumstances atfecting the wheat crops, probably gives reputation
to many other supposed means, natural and artificial, of destroying the injurious

fly.

Couper, of Georgia, addressed to Dr, Harlan of this city, in

After the reading of the Monthly Report of the Correspond-

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 8.8. Haldeman.

Hyopr. nebulosa. Globular, mottled with brown; a large central sub-rectan-
gular 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.

Hypnr. coceinea. Subglobose, uniform bright scarlet, legs slender, covered
with short bristles; palp: bristled, ante-penultimate articulation thickened.
Length 4 millim.

Hab. with the preceding. Differs from H. seabra, in beirg larger, and in
wanting the long bristles to the legs. The posterior legs are not “destitute of
cilia,’ wherein it differs from Limnochares extendens, Say.

Daranta reticulata. Ovate, margins imbricated, surface divided by fine lines
into minute rectangles ; posterior half of the body with the dorsal and ventral
portion approaching each other by similar curves, which meet ina long, slender,
tapering caudal appendage. Closely resembles “ Monocculus pulex.” Jurine’s
Hist. des Monocles, Pl. 8. fig.1. Leagth 14 millim.

Hab. with the preceding.

The Committee on Professor Locke’s communication, read
July 5th, 1842, on the Fossil Cryptolithus tesselatus, reported
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 soseldom 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 examininga stratum of clay-marl, which

Juny, 1842.] 197

constitutes, perhaps, a hundred feet in thickness of onr 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. James
Foster, a amateur collector of our city, discovered in this mari several specimens
of the above fossil, with the budy 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 Ist. hat 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 extibited in a specimen in Mr. Foster’scabinet; the
second fact in a specimen of my own, in which the shield has 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 Jateral 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-
dite family, the whole body would be concealed under the shield. The posterior
part of the body is circumscribed by a well defined raised inargin.

The associated fossils are Strophomena alternata, Atrypa testudinaria, Lingula

, Orbicula, Isotelus megistos, Calymene senaria, Orthocere, Enchrinites and
Corallines. Formation, “ Blue limestone,” ‘Trenton Limestone of the N. Y.
Geologists, or a formation above it.

The Committee to whom was referred a communication
by Peter A. Browne, Esq., describing a ‘“ monstrous Rose,’?
presented a report, stating that as the paper differed in charac-
ter so materially from those usually inserted in the Journal and
Proceedings, and in addition required a plate for its complete
elucidation, its publication, in its entire form, was rendered
impracticable.

The following portion contains some strictures on terms
used in Vegetable Physiology.

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,’ > 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.
{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
words “transformed,” 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 opinior 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 or decaying organized 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 afierwards by a retrograde
movement metamorphosed back again into leaves; when in truth all we mean
to assert is, that owing to the peculiar circumstances attending the develope-
ment 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 Academy, with the following result.

Also a letter from M. Louis Bellardi, dated March 25,
1842, in reference to the presentation of his work.

And a note from Peter A. Browne, Esq., introductory to
his Catalogue of West Indian Plants, &c.

VERBAL COMMUNICATIONS.

Dr. Morton laid on the table the remains of a human skeleton found by Mr.
J. L. Stevens in a vault or tomb at the ruins near Ticul, nineteen leagues from
Merida, in Yucatan. Dr. M. remarked that these bones have pertained to a
female, whose stature has not exceeded five feet three inches, at the same time
that the absence of epiphyses and consequent consolidation of the bones are
proofs of adult age. From the appearance of the teeth, however, which are fresh,
and not sensibly worn, and a line or furrow marking off the crista of the ilium,
it is presumed that this individual had not passed her twentieth year. The
bones of the head, which are still partially separable at the sutures, are admirably
characteristic of the American Race, as seen in the vertical occiput and the great
inter-parietal diameter, which measures five inches and eight-tenths. The head is
of full size, in proportion to the rest of the skeleton, of which the bones are of
very delicate proportions, especially those of the feet and hands. An interesting
feature of this skeleton is, the occurrence of a large spongy node on the upper
and inner surface of the left tibia, on which it extends about two inches in length,
one inch in breadth, and half an inch in thickness. Dr. Bridges having subjected
some fragments of these bones to the usual chemical tests, found them in a very

204 [Aveust, 1842-

great degree deprived of animal matter—an additional evidence of their anti-
quity.

Dr. Morton also exhibited parts of four other skeletons, obtained also in Yuca-
tan, by Mr. Benjamin A. Norman, during a recent sojourn in that country,
They were found in mounds near the sea-coast; but on a closer examination, it
was ascertained by that gentleman that these mounds had been pyramids of
mason work, which, by gradual disintegration, and subsequent deposits of vege-
table matter, had been reduced to the low, conical, or mound-like form. One of
these skeletons is that of a man of perhaps five and twenty years of age; the
bones, which are chiefly those of the extremities, are large, and indicate a person
of full stature. The few remaining cranial bones are large ard massive, which
remark also applies to both maxilla, in which the teeth are remarkably perfect.
The os calcis and other bones of the foot are of delicate proportions. Parts of a
second skeleton from the same mound are smaller, but so few, and so much
broken, as to prevent any certain indications of age or sex.

Of the tworemaining skeletons, only a few fragments of long bones and others
of the hands and feet remain. These are much larger than those already de-
scribed, and have probably pertained to men of large stature. No remains of
cranial bones were found among them These fragments were not tested for
the animal matter they may contain; but judging from their extreme disintegra-
tion, it must have almost wholly disappeared.

Mr. Gliddon remarked, on the authority of Mr. Stephens,
that an examination of the sepulchre, and of the mode in
which these remains had been interred, totally disproved
any idea of their being of Egyptian origin or character.

BUSINESS BY SPECIAL RESOLUTION.

On motion of Dr. Morton, Resolved, That the Catalogue
accompanying Mr. P. A. Browne’s donation of West Indian
plants, &c., be bound, and deposited in the Library of the
Academy.

VERBAL COMMUNICATIONS.

Prof. Johnson exhibited and explained a method of applying the galvanometer
to the purpose of testing the relative destructibility of different samples of sheath-
ing copper when exposed to the action of salt water. He referred to the fact
that, in early periods of the use of copper for sheathing the bottoms of vessels,
while iron bolts were still used for fastenings, the copper lasted much longer than
at present, while the iron itself was rapidly corroded ; that copper bolts having
been substituted for iron ones, the sheathing exhibited a much more rapid decay
than before. He likewise alluded to the fact that the practice of fastening on
sheathing copper with composition nails, offers an antagonist electric force to
that of the copper, rendering the latter more highly electro-positive, and thus fa-
cilitating 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 manu-
factured at the same works, and apparently with equal care in freeing the metal
from impurities.

It was further mentioned that long experience had evinced the uncertainty of
obtaining durable copper by efforts to approximate chemical purity in the manu-
facture, and that in copper free from other metals the oxide of copper is some-
times detected both in the interior and on the exterior of the mass, rendering it
earthy 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 of that metal which had been worn several years between the keel and the
false keel of an English sloop of war, where, though the salt water could pene-
trate and corrode it, the disintegrated particles could not be reached by the waves
to be washed away.

As the comparative electric energy of two sheets of copper is proportionate to
the amount of corrosion going on, and as the quantity of electricity set in motion
also determines the influence of its current on a magnetic needle, the deflection
of that of a common galvanometer may be made to determine the relation of two
sheets to each other, and thus to ascertain whether they are suitable to be asso-
ciated together on the botiom of the same vessel.

Two methods were described and illustrated by which this may be accom-
plished. The first is to oppose in succession the several sheets of copper toa

sheet of platina constituting the negative element of the pair, and observing the
deflections which the several copper sheets produce in the needle of the galvano-
meter. The other is to oppose all the sheets of sheathing copper to one of che-
mically pure copper deposited by the galvanotype process.

Both these methods were exhibited in connexion with several specimens of
sheathing copper, the specimens which had, by analysis, been shown to be the
purest copper, exhibiting the highest electro-positive energy when compared with
platina, and the lowest electro-negalive power when opposed to the galvanoty pe
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 practice,
is a triple astatic needle, having its middle needle within, its lower one below,
and its upper one above a spiral of copper ribbon, formed in such a manner as to
present the edges of the ribbon to the upper and ender surfaces of the needles.
The suspension may be either that of a pivot, or that of a single or double sup-
port of unspun silk. The liquid preferred for use, in this species of test, is com-
mon sea water; being the same te which practice subjects the sheathing copper,
and having the advantage of being easily procured, costing nothing, and capable,
therefore, of being renewed as often as the operator may think fit.

WRITTEN COMMUNICATIONS.

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 w should take the place of w in the Unio Cowperiana
of Lea,” on the ground of an error in the orthography. Mr.

dl

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 vertebrae 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 vertebrae 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, Arca pexata, Arca ponderosa, Lucina divaricata, Modiola late-
ralis, Tellina alternata, Mactra lateralis? Oliva literata, Natica duplicata,
Crepidula convexa.

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 2.43
Fixed Carbon, 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 semi-bituminous or
“transition” coals, such as that found on Stony Creek, in Dauphin county,
Pennsylvania.

In 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 sume coal, and as a

32

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 the
contrary, a peculiar propriety, inasmuch as neither of the other terms in
general use to desicnate 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, Orie

BUSINESS BY SPECIAL RESOLUTION.

By special permission, the Committee, consisting of Dr.
Goddard, Mr. Taylor, and Prof. Rogers, to whom was
referred a paper by Peter A. Browne, Esq., on the subject
of the supposed human foot prints found near St. Louis, in
the Carboniferous Limestone, made a Report 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.

MEETING FOR BUSINESS, AND ANNUAL MEETING.
DECEMBER 27, 1842.

VicE PRESIDENT MorTON in the Chair.

The Annual Reports of the Librarian, of the Treasurer,
and of the Publication Committee having 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 by Dr. F. Menké, 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. Menké. 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 Linnean 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,sthe West
Indies, Hungary, &c. cee

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, Reemer Goehnat, Lehmann, Salzmann, Rohde, Wendland, Meyer,
Shroeder, Ehrenberg, 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, Ly copodium, and
the Marsileacew, 29 species ; Hepaticee 65 species; Musci 309 species;
Algee 122 species; Lichenes 152 species; and Fungi 445 species. To these
are to be added 18 species of Corallia, and a number of plants Us which
neither the generic nor specific name was attached.

The whole has been distributed into thirty-seven folio volumes of large
size, occupying an entire case six and a half feet high, four feet wide, and
twenty-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 P. A. Browne, Esq.,
and Mr. R. C. Taylor; Dr. George Engelmann, of St. Louis, Missouri,
aud 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,

Wo. S. ZAntTzINaGER,
Rosert Brings,
, Gavin Watson.

have enabled him to correct
his description in several par-
ticulars, viz: “The appear-
ance that the shield covereda
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
Jigure ) The tail inthe most
perfect specimen consists also
of six articulations, each sub-
divided by an inferior joint
or depression, giving the ap-

pearauce of twelve articulations. The middle lobe of the
tail is itself trilobate, appearing like the whole body of a
small trilobate entire.’

JANUARY, 1843. | 237

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, 1843.

Vice Presipent Morrow 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.

he 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 Maclures ‘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 angmented 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

238 [JaNuARY, 1843.

whole amount has been deducted for their use; the balance, amounting to
$1519, is in Pennsylvania five per cent. stock, to which is to be added
$130 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 accordafice 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 Jast 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. Buta 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.

To the Geological department valuable donations have been made by

Dr. 8. G. Morton, Prof. Locke, of Cincinnati, Geo. R. Gliddon, Esq., of
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.
J. 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 Furness, 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. J. 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.

JANUARY, 1843. ] 7 239

Menke, of Pyrmont, Germany, has been at length examined and arranged
by the Botanical Committee, whose 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
through 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 handred. 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, fare 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

240 [Janvary, 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 cordition 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. Its therefore stil] 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

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

Recording Secretary.

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.

WRITTEN COMMUNICATIONS.

A letter was read from J. G. H. Kinberg, of Lund, Swe-
den, dated October 25, 1842, proposing exchanges in Natural
History.

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
28; 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-

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 [Fesruary, 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
then 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 s/a’y Cannel, from Kentucky, and the other from Missouri,
called floating Cannel, from the circumstance of its floating on waters
which fluid it afterwards absorbs, and then sinks. Prof. Johnson also
gave the results of his analysis of these coals, which accorded in most
respects with that of the Cannel Coal of Scotland, as obtained by Mr.
Richardson.

VERBAL COMMUNICATIONS.

Professor Rogers remarked, in reference to the fossil
specimen presented this evening by his brother, that no
recent contribution to our Palzontology was more inter-
esting at this time than the discovery, by the latter, of this
familiar Kuropean 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
Kurope, 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.

WRITTEN COMMUNICATIONS.

Mr. Phillips read a communication addressed to the
Academy, from Mr, John G. Anthony, of Cincinnati, Ohio,
dated February 19, 1848, 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. ex¢isa,’ 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 Rafinesque, 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 Rocky 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 Royal Academy of
Sciences of France, dated Paris, January 19, 1848, and from
Prof. Berzelius, Perpetual Secretary of the Royal 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. sii 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 River and the
Rocky 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.

VERBAL COMMUNICATIONS.

Prof. Henry D. 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 ont, 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 confirm 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.

MEETING FOR. BUSINESS.
APRIL 25, 1848.

Vick 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, Hsq., 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 brogyn fragments, showing a loss of 17.5 per

“
a

cent. of w
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
rare Birds of the Rocky Mountains and California,” reported
in favor of its publication, with the exception of the generic
and specific characters of the Hudromus 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
and California, at the instance of Mr. Nuttall, to whom this paper was
originally addressed, and by him referred to the Academy for Publication.

APRIL, 1843.] 259

Picus* Nuttali.

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. ‘I'wo 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 té dé dé dé, then altering to dé dé diit, 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, 1848.

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.

Frinattia Blandingvana.t

Male.—Above olive green tinged with cinereous and brown. Crown
rufous 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 which is a line of blackish tipped with
cinereous. Sides brownish; belly and vent 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 singularly marked species I procured a single
specimen only, in September, on the bank of a small stream in the
Rocky 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.

Lopyortyx* Gambeli, Nutt.

Cinereous-brown above; head bright rufous; crest of six black
feathers one and three-fourths inches long, wide at the tips and cury-
ing forwards ; throat black, banded by a line of white; front of long
grayish and black bristly feathers, with a band 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, cinereouws 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

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.

Lantus elegans. White winged Shrike, Swains.

This species, of which but a single specimen is known to 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. .

Scrurus tenuzrostris? 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. Wings 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 8. Noveboracensis, which they
somewhat resemble; they also uttered, when flying, a few slender
notes.

Swainson questions the 8. 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.

Pritogonys Townsendi7, Aud., Nutt.

This rare and singular bird, of which but a single specimen has
been obtained in Oregon, I first met with, in October, oi 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 ofa fly- catcher, and I never
heard it utter a note.

Turpus 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 tke 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.

Frincitua Gambeliz, 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?

Eryturospiza frontalis, 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
Resolutions offered at previous meetings, to alter Article L,
Chapter III, of the By-Laws, reducing the amount of the

Apri, 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.

ELECTION,

Robert Kilvington, of Philadelphia county, was elected
a Member 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.

Cast or model of the stump of a fossil tree, found near New
Harmony, Indiana. This cast represents but one-fourth
the size of the original specimen, which is nearly two
feet in height, and from nine to ten inches in diameter.
Presented by Dr. D. D..Owen, of New Harmony.

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. O. 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.

Dr. Owen exhibited several charts and a large number of
very interesting colored drawings, all executed by himself,
illustrating the geology of the Western country. These
drawings represented all the known fossils characteristic of
the various strata of Indiana, Ohio, Illinois, Kentucky, &c.,
mostly on a magnified scale. Dr. Owen entered into a de-
tailed explanation of these drawings, and pointed out the
fossils peculiar to each of the formations.

Professor Rogers followed with some general observations
on the geology of the Western States, and also called atten-
tion to the remarkable character of the anticlinal axis repre-
sented in one of the charts exhibited this evening, which

VERBAL COMMUNICATIONS.

Dr. Morton, (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-

Junn, 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. Miitter 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 cesophagus or
stomach.

Mr. Lukens mentioned that with Mr. T. R. 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 Ist July, Dr. McHuen (then Recording
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. Ruschenberger, 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. Rogers 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 ata 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. septemdecim 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
county, 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 1856.

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 the 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 cope the life
of the chick.

Vice Presipent 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 Tyrannule.

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, &c. 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 blaek. 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

281 | Jury, 1843

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; extent8 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 ‘I’. virexs, 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 ani lever tail coverts yellowish white. Tail emarginate. Second
aud thiid pri:oaries longest, first longer than sixth. Bill horn colour be-
neath.

Description of a Male,

Tvrm, &e. Body rather slender. Bill ssnaller than the other species of

te secus. “Tisous si idly longer than the middle toe. Second primary

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 24
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 Tyrannule. 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 first longer 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. Jt 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.

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, 1843, 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 Ist 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 Meris, just published by the Egyptian Society,
had been sent to the Academy, and would be presented as
soon as received.

ELECTION.

The Hon. .and Rev. William Herbert, of Manchester, En-
gland, was elected a Correspondent of the Academy.

Descriptions of North American species of Coleoptera, presumed tobe undescribed.
By S. S, Hatpeman.

From the difficulty attendant upon the study of insects in the United States,
arising from the absence of standard collections, and the impossibility of know-
ing what has been done in Europe, the characters here given should, perhaps,
be regarded as indicating species unknown to the author, rather than as abso-
lutely new to science.

Cyminois neglecta. Head and prothorax black, thinly marked with rufous
pile ; head punctured ; mouth, antenne, and feet rufous: prothorax lengthened,
and much contracted behind, scabrous with numerous deep punctures, mesial
line and lateral submargin depressed: elytra reddish brown, crenate-striate, in-
terstices narrow. 8 millim. long. General appearance of C. pilosa, Say.

Dromtvs apicalis. Head black ; prothorax reddish-brown, with a testaceous
margin ; elytra brown, with the tip, and a large irregular spot very near the base,
pale testaceous: body beneath, legs, antenne, and palpi of the latter color. Not
quite 4 millim. long.

Dromivs geminatus. Brown, head black; antenna, a large oval spot near
the base of the elytra, and a small circular one at the inner extremity, testaceous.
4 mill. long.

Procaronvs timidus. Dull reddish brown above : antenna, legs, lower sur-
face and lateral margins of the prothorax and elytra, testaceous: elytra wide, deeply
striate, interstices convex. 8 mill. long. Var. Base of the elytra, and a large
spot upon the suture, behind the middle, obscure. Hab. Alabama. P. timidus.
Hentz MS.

Lesia brunnea. Fuscous, head and pronotum blackish : thorax beneath, mar-
gin of the pronotum, palpi, 3 basal articulations of the antenn», a spot anterior
to the middle, and equidistant from the suture and limb, and a smaller obsolete
one at the tip of the elytra, pale testaceous. 44 mill. long.

Corropera fasciata. Head and prothorax shining black, with a tinge of green-
ish: beneath very dark brown: tarsi and extremity of antenn» pale brown:
antenna, legs, and elytra, pale ochraceous; elytra striate, mottled with brown
about the middle, and with a large spotat the inner base and tip. 44 mill. long.

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 Miocene, and one
Eocene Fossil Shells of the United States.

By T. A. Conran.

* CanpITAMERA,

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 coste 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 striz, 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 strie; 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. cadliplewrais not ~
flattened posteriorly on the disk, and the umbonial slope is slightly arched in
the middle, while in the triquetra it is somewhat concave.

. Nucuta.
N. liciata. Ovate-acute, ventricose, with about 15 concentric Jamelliform
strie ; posterior side much shorter than the anterior; anterior side slightly re-

curved, with an oblique slight submarginal furrow, causing aslight emargination
of the basé near the extremity.

Locality. Cliffs of Calvert, Md.

306 [Ocroner, 1843.

‘PecTUNCULUS.

P. parilis. Orbicular, slightly oblique; height and length equal ; posterior
superior margin obliquely subtruncated ; ribs defined by slightly impressed
narrow radii; radiating striw minute and obsolete; marginal teeth prominent.

Locality. Cliffs of Calvert, Md.

Differs from P. carolinianus, in being oblique, natrower 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 strix; 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. Tuomey.

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 cost ; young shells have the superior valve frequently slightly
concave.

2. P. fricenarius. 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.vicenarius. 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.

TELLINA.

1. T. lenis. Subellipticai; 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 antcrior 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.

Ocroser, 1843.] 307

> Lucia.

L. multistriata. 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; !unule elliptical, slightly impressed. Height one-third of
an inch,

Locality. Wilmington, N. C.

. AMPHIDESMA.

A. zquata. Longitudinally oval, convex, with about 17 laminated concentric
striz ; 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.

. Crepipura.

C. spinosa. 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. costata, Morton, in wanting the numerous fine coste, and in
having fewer, much longer, and thicker spines.

. Furevr.

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 tuberculated carina, the margin of which presents a waved outline, the
tubercles being obtuse ; spire prominent, profoundly channelled at tke 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 [OcTosEr, 1843,

when adult, there are 17 much less elevated, more irregular, and more obtuse
tubercles.
. Buccixum.

1. B.protractum. Subfusiform, elevated ; with robust, flattened spiral ribs
about as wide as the interstices, both ribs and furrows crossed by distinct promi-
nent longitudinal lines; aperture long and elliptical ; labrum with short, sub-
marginal prominent lines; beak slightly recurved. Length, one inch and a third.

Locality. Calvert Cliffs, Md.

2. B.lienosum. Obovate, with distant spiral flattened, not very prominent
lines, between which are usually 3 lines, the middle one largest; whorls of the
spire slightly convex ; body whorl ventricose; lines of growth distinct; colu-
mella with two distant plaits, the inferior one at the angle which is prominent.

Length, one inch and two-thirds.

Locality. Calvert Cliffs, Md.

3. B.(Pollia) filicatum. Short-fusiform, whorls 5 or 6, sub-scalariform,
with very prominent spiral strie, and one or two intermediate finer lines ; whorls
with longitudinal distant ribs; aperture rather less than half the length of the
shell; beak short; columella with slightly prominent folds; labrum with acute
prominent lines obsolete on the margin, and extending far within the aperture.

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. Acutely oblong-ovate, with regular prominent com-
pressed longitudinal ribs, and fine revolving lines, one or two of which, near the
suture are larger and more distinct; towards the base the lines are more pro-
found ; spire elevated; volutions 9, with straight sides; suture impressed ;
aperture about one-third the length of the shell; labrum with 6 dentiform tu-
bercles within. Length haif an inch.

5. B. bilix. Elliptical, thick, with alternated revolving lines crossed by
rugose lines of growth; spire conical, volutions convex; one or two towards
the apex longitudinally ribbed ; suture profound; aperture about two-thirds the
length of the shell; labrum ribbed within. Length one inch.

Locality. James river, Virginia.

6. B. fossulatum. Subovate with numerous impressed alternated revolving
lines; body whorl ventricose; whorls 4 or 5, sides convex ; spire somewhat coni-
cal, with a channel at summit of the volutions, which has a rectilinear slope to
the suture ; columella short ; fold at base of the shell acutely carinated. Length
one inch and a third.

7. B. preruptum. Ovate-acute, with longitudinal very regular and equal
compressed ribs, and regular revolving raised lines, about 12 on the body whorl,
at base of which is a broad fold with 4 revolving lines on it; labium reflected ;

columella obliquely truncated at base ; aperture rather more than one-third the
shell’s length. Length one-third of an inch.

. CaANCELLARIA.
C. corbulu. Short, subovate; whorls sub-scalariform ; ribs 8 or 9 on the

Resembles somewhat V. punctulata, Val. (Enc. Method. t. 267, p. 4.) of
Florida, but has much more prominent, narrow and more remote ribs. In this
respect it differs also from V. cortinaria, Rodgers.

PuicatTuta.

P. densata. Ovate, thick, profoundly and irregularly plicated ; inferior valve
ventricose, its ribs acute, with arched spiniform scales; cardinal teeth large,
curved, laterally striated, crenulated on the margins; larger cardinal tooth in each

valve slightly bifid, broad; muscular impressions prominent. Length one inch
and an eighth.

Locality. Cumberland co., New Jersey.

The valves have about 10 folds, and the lower valve closely resembles a varie-
ty of Ostnea virginiana.

Creriputa.

C. densata. Oblong, thick and ponderous, profoundly ventricose, with coarse
lines of growth; umbo very prominent, somewhat compressed; diaphragm
slightly depressed on each side, the margin much contracted, near the middle

angulated ; from the angle to the anterior side rectilinear. Length ene inch
and a quarter.

Locality. Natural well, Duplin co., N.C.

Differs from C. costata, Morton, in the profound angular emargination of
the diaphragm, in being proportionally narrower, and without ribs or strix.

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 inextent. One half of this marsh is covered by a soil differ-
ent from that composing the marsh itself. This soil appears to

i

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.”

Descriptions of nineteen species of Tertiary fossils of Virginia and North
Carolina.
By T. A. Conran.

. Anomta,

Anomra Ruffini. Subovate or suborbicular, irregular; larger valve with
concentric lamine, 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 Roffin, 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; umbonial 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, cren# 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. Ruffin.

Perhaps this may prove to be an old specimen of A. arata, Say.
44

324 [DeceMBER, 1843.

Anca 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.

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 anda half
inches; height, one inch and seven-eighths.

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 capar. 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. mercenaria, 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

deeply impressed line ; posterior side subcuneiform, extremity obtusely rounded
or subtruncated ; cardinal plate broad: muscular impressions large; margin
strongly crenulated. Length, seven inches.

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.

Lontrss.

Lortrzs 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. Miocene?

Proportionally more elevated than Lorires americana ( Mysia,) thinner, not
oblique like that species, and very distinct.

- Soren.

1, Soxxn 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 ?

326 [DeceMBeER, 1843.

T am doubtful of the geological age of the three fossils above described, as we
know not the group among which they occur.

2. Sorew ensiformis. Linear, slightly curved, gradually narrowed from
the middle to the posterior extremity, which is subeuneiform ; anterior margin
obliquely subtruncated. Length, three inches.

Locality. St. Mary's river, Maryland. Miocene.

. Turritretta.

Tourniretta bipertita. 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 carinuted 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. ;

. Scanarta.

Scatarra 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.

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.

, Buccrnum.

Buccixum 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-
tare 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.

channel rather less than half the length of the shell; labrum with eight short
dentiform prominent strie 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.

Terenra 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 Cenrratum 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.

TuRBINOLIA.

Torsrnorta pileolus. Obtusely obconical, slightly compressed, periphery
with an oval outline ; lamella smooth, of equal thickness, united to an elliptical
centre; between each plate is one, sometimes two, short irregular lamelle,
either free or united to the base of the larger rays. Length, nearly half inch,
diameter, half inch.

Spatanevs orthonotus. Ovate, convex-depressed ; truncated at each end,
more elevated anteriorly than posteriorly ; dorsal line of the suture a little ele-
vated, and curved gradually to the mouth on the anterior half; on the posterior,
straight to the margin and parallel to the base; canal very wide and slightly
impressed on the back, margined by an obtuse carinated line and slight furrow ;
on the periphery the canal is deep and angular; ambulacra rapidly expanding
from the extremities towards the dorsal suture; pores disunited ; in the middle
of the back a slight furrow crosses obliquely each of the anterior ambulacra at
its termination; base plano-convex; anus large and remote from the margin ;
granulations on the back minute and very closely arranged, in the canal much
larger and unequal in size; base with large tubercles, becoming gradually
smaller and more closely arranged towards the margins. Length, two inches

OssERVATIONS.

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 inevery 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* Patonprna 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 situatiunsin 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 Crrenap. 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
notin the least abraded, a circumstance which indicates the vicinity of the
Petersburg deposits to the mouth of ariver. 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 Panopaa, but also, though less frequently, with the large Venus tridacnoides,
Crassatetra undulata, Astante concentrica, Crraznsa 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

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

- Pootapomra abrupta.

which Deshayes has referred to Panopewa. I carefully removed the marl from
the hinge, in order to ascertain if there was an erect curved tooth as in Pan-
opea, 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 Panopea; the pearliness of the substance and
the absence of a cardinal tooth. A true panopea is never pearly, any more
than a Unio is ever otherwise.

Observations on the Lead Bearing Limestone of Wisconsin, and descriptions
of anew genus of Trilobites and fifteen new Silurian fossils.

By T. A, Conran.

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 Bettenorunon 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., Betrexoraron bilo.
batus, a Strophomena like Onrais alternata, Sowerby, a common shell in the
New York Trenton limestone, and an Orthis resembling O. testudinaria, 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 BreLrLenoraron,
three species of Propuctvs 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, Cenaunus pleureranthemus, Isorexus gigas, and
InLu=xus — ; and of the shells, Srroppomena sericea, PanaGMOLITES
compressus, and Bettrroraron bilobatus. With these are a large Cytherina,
known also to occur in the Trenton limestone of New York: the Tenenra-
tuLa (Atrypa) Schlottheimii of Von Buch, and some beautiful new species of
bivalves. ‘The limestone is very compact, replete with shells and favosites, of
a light color, inclining to drab, and it immediately underlies the rock in which
the galena occurs, as Mr. Taylor informs me. Many of the fossils are loose
and exceedingly well preserved, having apparently come from a soft limestone
shale.

In examining, a few years since, some specimens of limestone brought from
Galena, by the late lamented Nicollet, and which he informed me, was the rock
immediately below the lead-bearing strata, I recognized the group of fossils
which characterize the Trenton limestone, but Mr. Nicollet was unable to pro-
cure any organic remains from the overlying rock, which might furnish a clue
to its geological age. Mr. Taylor has fortunately obtained this desirable object,
in Wisconsin, having discovered not only well preserved fossils, in the lead-bear-
ing formation, but even shells and remains of crinoidea replaced by the
sulphuret of lead. There is particularly the cast of a large Turritella com-
posed entirely of this mineral, and a specimen of Pirevroromaria angulata,
which is a limestone cast, with the upper part of the spire of galena, and from
fragments yet remaining between the caste and matrix, it is evident that the
shell itself had been replaced by the sulphuret of lead. These two shells are
not uncommon in the Trenton limestone of Lewis county, New York. The
Turritella [ have never known to occur in any other formation but the Pleuro-
tomaria I found also in the Salmon river, or Pulaski shale, near Rome, Oneida
county. Mr. Taylor has likewise a crinoidal column, almost wholly replaced
by galena: it has distant very prominent rings or ridges, and is a species which
has been observed in the Trenton limestone of New York.

From the evidence it is clear that the limestone of Galena, Illinois, and of
Mineral Point, Wisconsin, in which the lead occurs, is certainly not of more
recent date than the Pulaski and Lorraine shales of New York, and the cara-
doc sandstone of Great Britain : but [ believe it will prove to be an upper mem-
ber of the Trenton limestone formation.

Mr. Taylor has also a specimen of Trenton limestone, precisely similar to
that of Galena and Mineral Point, which was found in Wisconsin, 40 miles
N. E. of Galena.

There is a specimen of the sulphuret of lead, among the cubes of which is
imbedded a single valve of Strophomena, very thin and silicified.

Mr. Taylor brought the Pentamenvs oblongus, Catenirona escharoides,
and C. labyrinthica, which were found together on one of the hillocks or
« mounds,” as they are termed in Wisconsin. These two fossils, when associ-

Lower Silurian group.

‘T'narxops ovata, Obtusely ovate, surface minutely punctate; head very wide,
lunate, involuted ; eyes very prominent, rounded, smooth, placed on a line with
the angle in the middle of the side lobes; ribs flattened, smooth, without a_bor-
der at the extremities where they are rounded and not expanded ; post-abdomen
with the middle lobe convex, rounded and well defined at the extremity ; inferior
margin obtusely rounded. Length two-thirds of an inch: width of buckler
three-quarters of an inch.

Locality. Minéral Point, Wisconsin, (blue limestone quarry,) Mr. Taylor.

This rare trilobite may be studied as well in Mr. Brano’s excellent model, as
in the natural specimen. It is probably a rare fossil that few naturalists will be
able to procure, and for this reason we would recommend the model to those who
ase desirous to have a knowledge of the genus.

Wherever many entire trilobites are found, a very quiescent state of the
waters wherein the rock which contained them was deposited, may be inferred
from the abundance of scattered bucklers and post-abdomens, which occur in other
strata where there is no evidence of violence on any of the delicate shells accom-
panying them ; the articulations of the abdomen were therefore held together by
a frail ligament, whilst the post-abdomen although ribbed in many species, was
in all composed of an‘inarticulated crust and thusis almost always preserved en-
tire in the rock.

The Recording Secretary then read his Annual Report,
which was ordered to be published in the Proceedings.

REPORT
OF THE
RECORDING SECRETARY
For the year 1843.

In the Report, which a twelvemonth since, in accordance with the estab-
lished rule of this Institution, it became my duty to present, it was the design
throughout to place before you a candid statement, embracing ¢ very circum-
stance which it was believed would tend to give an encouragting view of
its condition at that time, and of its future prospects. :

A review of its proceedings for the present year will furnish conclusive
evidence that we have continued reason to be gratified with its position and
success.

At home and abroad, its members, correspondents, and friends have
given ample proof of their zeal and interest in its welfare. The contribu-
tions to its Library and Collections have equalled those of former years ;
its usefulness has been thereby increased, and the field for investigation
and the study of the Natural Sciences enlarged. In all the departments
this has been the case, as the following summary will show :

In Geology and Mineralogy there have been received twenty-three do-
nations from the following: Drs. Burrough; Morton; Elwyn ;
Blanding; Lafon; Goheen, of Liberia, Africa; D. D. Owen, of
New Harmony, Indiana; Fussell, of Indiana; B. B. Brown, of
St. Louis; Professors Forchey, of Natchez, and H. D. Rogers; and
from Messrs. French and Deinestre, of New Orleans; Codwise,
of St. Croix; J. Cassin; S. B. Ashmead; W.S. Vaux; G. R.
Gliddon; Marsh; Land; Lessig, and Stephen Taylor, Jr.

In Ornithology, eight donations, from Dr. G. Watson, and Messrs,
J. Cassin; Baird, of Carlisle, Pennsylvania: J. G. Strain,
U.S. N.; J. Dundas, and Miss Percival, of Philadelphia.

In Zoology, three donations, by Mr. Cassin, and Dr. Wm. Blanding.

In Entomology, ten donations, by Drs. Watson, Owen, and Blanding;
and Messrs, Kilvington, Ashmead, Cassin, and Strain.

In Icthyology, six donations, by Dr. J. Carson; and Messrs. Cassin,
W. B. Maull, and Philip Lowry, Jr.

In Herpetology, seven donations, by Messrs. James Read ; W.S. Vaux;
J. G. Strain; B. M. Norman, of New Orleans; and Drs, Go-
heen; C, W. Pennock; and P. B, Goddard.

336 [DecemMBER, 1843.

In Helminthology, one donation, by Mr, William G. Burke. :

In Conchology, seven donations, by Messrs, J, G. Anthony, of Cin-
cinnati; C. M. Wheatley, of New York; Dr. J. C. Jay, of do.;
Professor Forchey ; Mr. Thomas Beasley, of New Jersey ; and
Messrs. Ashmead and Cassin.

In Osteology, two donations, by the Messrs. Baird, of Carlisle, and
Dr. Goheen.

In Botany, five donations, by Messrs. J. N. Nicollet; P. A. Browne;
Mr. Codwise, of St. Croix; Mrs. Wm. S. Biddle, of Phila-
delphia, and Dr. Goheen.

The most interesting and valuable accession to the Museum during the
year has been that of an articulated skeleton of an adult male Chimpan-
zee, Troglodytes niger, Geoff., received from Dr. S. M. E. Goheen, of
Liberia, Africa, and one of the Correspondents of this Institution. ‘The
skeleton is deficient only in the sternum, the two patelle, and some of the
smaller phalanges of the feet and hands. For these, similar bones of a
young human subject have been substituted, so that the specimen appears
perfect,

I have the satisfaction to state that during the last season the interest in
the Entomological department has been revived, and that to several
sources, but especially to our fellow members, the Messrs. Ashmead, Mr.
Kilvington and Dr. Watson, is the Academy indebted for a considerable
accession of native insects, Fora long period, little or no effort has been
made in this department. The valuable collection presented to the Aca-
demy by the late Mr. Say has been entirely lost or destroyed, and the
beautifully arranged and costly cabinet of Drs. MeMurtrie and Pickering
has very nearly shared the same fate. Of other minor donations the bare
fragments can be found. Various plans have been resorted to, in the hope
of preventing these losses, but hitherto without success. Under such dis-
couragements, it is not surprising that this department should have been
neglected of late. To the donations mentioned, have been added the best
and most perfect specimens selected from the collection of Drs. McMurtrie
and Pickering, and all have been carefully disinfected by exposing them toa
high temperature for many hours. A new method for preserving them
from future injury has been adopted, which it is believed will be effectual.

The collection of Reptilia, during the last summer has been removed from
the Hall’ to the room on the ground floor, and now occupies the cases
formerly containing the collection of crania belonging to Dr. Morton.
The members must have observed great improvement in the new
arrangement of the specimens, which have been greatly increased in
number, and each one carefully examined, the bottles and jars contain-
ing them refilled with alcohol, and new labels added. In fact, the extent
and value of this collection could not previously be properly appreciated,
It will now bear comparison with any in this country.

The large and fine collection of Birds in skin, possessed by the Academy,
has been thoroughly overhauled, and the imperfect specimens, or which
had sustained injury from insects, have been removed, and the rest disin-
fected by exposing them to a high temperature in a large copper apparatus
provided for the purpose. The collection is now in the best order for
mounting or exchange.

DeceMBeER, 1843. ] 337

The accessions to the Library have exceeded those of the year previous,
They consist of one Folio; eleven works in quarto form, including the
Memoirs and Transactions of learned Societies ; sixty-five octavos and
duodecimos, including Journals, Annals, Bulletins, &c.; and seventy-two
productions in pamphlet form, or in numbers, consisting of Reports, Pro-
ceedings of Societies, addresses, discourses, memoirs, &c. ‘To these are
to be added several manuscripts, charts and engraved copper plates. Of
the whole number contributed, twenty-nine thave been derived from Socie-
ties, sixty-three from Members, and the remainder, amounting to sixty-
seven, from correspondents, authors, editors, &c.

The papers read before the Society, and published in its Proceedings
between the Ist of January and Ist of November of the present year, are
four in number. The first is by Mr. William Gambel, of this city, and
contains descriptions of some new and rare birds of the Rocky Mountains
and California, the tour of which he has recently made. The second is
from the Messrs. Baird, of Carlisle, Pennsylvania, and describes two new
species of Tyrannula, from Cumberland county, Pennsylvania. The third by
Mr. Haldeman, is entitled a ‘Catalogue of the Carabideous Coleoptera of
South Eastern Pennsylvania, and descriptions of new North American
species of Coleoptera :”’ and the fourth paperentitled ‘* Descriptions ofa new
‘getius, and of twenty-nine new Miocene, and one Eocene fossil shells of
the United States,” is contributed by Mr. T. A. Conrad,

The publication of the Proceedings has been regularly continued during
the year. It has now attained sufficient bulk to authorise the Committee
to bring the first volume to a close with the coming number. On the first
of November last, two years and seven months had elapsed since the first
number was commenced, and in that period 311 pages of matter selected
from the minutes of the meeting have been issued, or an average of about
120 pages annually. As every care is taken in the style and execution of
this periodical, to render it worthy of the Institution whence it emanates,
and a considerable expenditure is therefore incurred, itis proposed to give
here a condensed summary of the contents of the present volume, as far as
published, in order that some idea may be formed of its merits and utility.

Its first and most obvious advantage is in being a medium for commu-
nicating to the scientific public discoveries and observations at short
intervals of time, and thus often enabling the claim to priority to be
securely established. There have been, with this view, offered to the So-
ciety, and printed either entire or in part in its Proceedings, during the
period above mentioned, upwards of thirty original papers on scientific
subjects, the titles and authors of which are as folldws:

By Dr. S. G. Morton, two papers, viz., “* Descriptions of several new
fossil shells from the cretaceous deposits of the United States,” and ‘* De-
scriptions of two new species of fossils from the lower cretaceous strata of
New Jersey.” By Mr. T. A. Conrad, three papers; ‘* Descriptions of
three new species of Unio from the rivers of the United States;” * De-
scriptions of twenty-six new species of fossil shells from the medial ter-
tiary of Calvert Cliffs, Maryland,” and * Descriptions of a new genus,
and of twenty-nine new Miocene, and one Eocene, fossil shells of the
United States.” By Professor Johnson, two papers; ‘An examination
and analysis of coal from Arauco, Chili;” and ‘ On the relation between
the coal of South Wales and some Pennsylvania Anthracites.” By Mr.
Phillips, three papers; ‘Descriptions of two new American species of

338 [DecemMzER, 18498.

Helix; ‘* Memorandum of dates of publication of papers in the early
numbers of the Journal of the Academy,” and “On the nomenclature of
Natural Science.”” By Mr. Haldeman, the following papers: ‘ Descrip-
tions of new species of Cyclas ;” several on new species of Cypris; ** De-
scriptions of two new fresh-water shells of the genera -.mnicola and
Physa;” ‘of another new species of Cyclas;” ‘of a genus of Sterel-
mintha ;”’ “* of two species of Entomostraca, and two Hydrachne;” * of
a new Daphnia;”’ several on changes of nomenclature in Natural History;
a ** Catalogue of the Carabideous Coleoptera of South Eastern Pennsyl-
vania, and descriptions of new species of North American Coleoptera;”’
and * Description of a new species of Pasimachus.” By Dr. Hallowell,
a paper describing a new species of Chameleon from Africa. By Dr.
Benj. H. Coates, a paper on ‘** The natural alliances of the genus Cecido-
myia,’’ By Peter A. Browne, Esq., a portion of a paper containing stric-
tures on terms used in vegetable physiology. By Mr. William Gambel,
** Descriptions of some new and rare Birds of the Rocky mountains and
California.” By the Messrs. Baird, of Carlisle, Pennsylvania, ‘* Descrip-
tions of two new species of Tyrannula from Cumberland county, Pennsyl-
vania.”” By Professor Locke, of Cincinnati, ** Observations on Crypto-
lithus tesselatus,”” By J. Hamilton Couper, of Georgia, ‘* A description
of the strata in which were found the valuable fossil bones and shells
from the Brunswick Canal,” presented by him to the Academy. By Dr.
Clapp, of New Albany, Indiana, a paper in reference to the geological
equivalents of that vicinity, and of those of the falls of the Ohio. By
Miss Morris, of Germantown, ‘ Observations on the development of the
Hessian fly.”” By Messrs. Audubon and Bachman, * Descriptions of
new species of North American Quadrupeds;’’ and by Dr, Ravenel, of
Charleston, ** Descriptions of several new fossil Scutelle.”

The communications made before the Society in a verbal form, and re-
corded in the Proceedings, are even more numerous, and ecntain much in-
formation on important and interesting facts in natural science. The
limits to which this Report is necessarily restricted, will only admit
of the mention of the names of those gentlemen who have most largely
contributed to this portion of the Proceedings. There are—from Dr.
Morton, six commanications ; from Prof. Johnson, twenty; Prof. Rogers,
five; Mr. S. S. Haldeman, four; Dr. B. H. Coates, three; Mr. Phillips,
two; Dr. George C. Leib, three: Dr. Chaloner, four; Mr. Joseph A. Clay,
one; Dr. Blanding, one; Dr, Bridges, two; Prof. Bailey of West Point,
one; Mr. Quimby, two; Dr. Goddard, five; Mr. George R, Gliddon,
two; Dr. Elwyn, one ; and from Dr. Owen, of New Harmony, two.

This publication also records for the period mentioned, 219 donations to
the Museum of the Society from 110 individuals; and 281 donations to
its Library, 68 of which are from Societies, and 213 from individuals.

Another most important advantage derived from it is in its general dis-
tribution to foreign and domestic Societies and Correspondenis, Nearly
one hundred and fifty copies of each number as it appears are sent, not
only in every direction throughout the Union, but to various sections of
the globe, and a correct ape of the character and standing of this
Institution is thus widely diffused. 1 have transcribed from the Memo-
randum Book of the Corresponding Secretary, the following list of Socie-
o receiving copies of the Proceedings, either regularly or as opportunity
offers :

Royal Society of London; Botanical Society of London; Zoological

In short, the reputation of this Institution has been greatly enhanced
since the adoption of this mode of publishing periodically an account of

its Transactions, and the propriety of its continuance cannot be ques-
tioned.

Three alterations in the By-Laws have been made during the present
year. The first reduces the amount of the Initiation fee from $10 to $5,
and the second reduces the amount of a life subscription from $80 to $50.
Both of these alterations have been in contemplation for a length of time,
but no action determined on until within the last few months, when the
expediency and even necessity of adopting them were so obvious as not to
admit of longer delay. The third alteration requires of Correspondents
residing within the United States, elected after the 31st of January, 1843,
a small diploma fee. ‘This is a measure which the Society is justly en-
titled to adopt, and is only in accordance with the usage of most Institu-
tions of a similar character, The demand has been cheerfully complied
with in every instance where the receipt of his notice of election has been
acknowledged by a Correspondent,

Between the Ist of January and the Ist of December of this year the
Academy has added eleven new Members and twenty-one Correspondents
to its list. Of the latter, twelve reside in the United States, and nine

are foreign, The numberof members elected is nearly double the average
of the three preceding years.

The finances of the Academy are in a most favourable condition, as the
Report of the Treasurer will show. The right of way to a small portion
of the lot in the rear of the building, was disposed of in the early part of
the year for the sum of $660, to the holders of the adjoining property.
The offer was an advantageous one to the Academy, and was promptly ac-
cepted by it. A heavy ground rent held by the original owners of the lot
on which this building is erected, has been recently paid off by the next
purchaser. This is a source of some gratification to the Academy, as re-

lieving it from a possible contingency which might involve its interests in
some degree. By the prudent management of the T'reasurer, the Institu-
tion has been enabled to meet all its ordinary annual expenses, and some
new arrangements for the coming year proposed by him, will, if carried out,
materially lessen its remaining obligations, which, although now compa-
ratively light, still prevent that entire appropriation of its annual income
to the general purposes of the Institution, which is so ardently desired
by all its members,
All which is respectfully submitted by

W.S. Zanrzincer,

Recording Secretary.
