Maclure, Ord, and Say, from their voyage to Florida, and Mr. Nuttall, in his last journey up the river Arkansa, brought back with them se- veral species of fish, which it is my desire to commu- nicate to this society. Several of them are unde- scribed, and one of them appears to constitute a new genus, allied to Cyprinodon ; if we may admit for distinctive character the form of the body, that of the fins, their position, and particularly that of the anal one placed exactly between the ventral fins; the last of which characters appears to me of peculiar im- portance ; it has likewise four or five branchial rays, and the remarkable teeth of Cyprinodon, whether or not they exist in the pharynx, as in that genus, I have not been able to ascertain. ‘The other species of fish which form the subject of this memoir appertain to the genus Peecilia, of Schneider, and Lebia of Cuvier. ) I would here observe generally, that all these spe- cles possess a form of body sufficiently similiar among themselves; that they are all of small magnitude, with the body and neck compressed and elevated anteri- orly; the tail compressed, and wide in proportion, but narrower than the anterior part of the body taken be- tween the back and the ventral fin ; the hea: is flat- tened and terminated by a cuneate snout, cleft cross- ways by the mouth, of which the jaws are protractile.

Snout short, jaws very protractile and narrow, armed with compressed and curved teeth, each terminated by three or four points. Head flattened above, between the eyes; the greatest thickness of the body is be- tween the opercula, very compressed towards the tail. The opercula are large and strong, and with- out denticulation. Eyes large, approaching the end of the snout, and placed at the summit of the head. Anterior lamina of the operculum, scaly, poste- rior lamina even, perhaps deciduous. The scales which cover the body are large, and more truncated than arounded, marked with concentric lines.

The small fish to which [ now call your attention. apparently occupies a place between the Genus Saurus and Scopeles of Cuvier. The individual here described, is from thirteen to fourteen lines in length, with the body compressed as in the herrings, and having in common with them, the argentine color of the abdomen, with the back of a deep blue. The snout, or terminating portion of the head, is very short, and truncated; the opening of the mouth oblique, the cleft not passing beyond the parallel of the eye; the maxillary bones long, and narrow, the inter-maxillary very small, set with minute teeth, the former, and the wings of the palate are equally fur-_ nished with them,as well as the rays which form the opening of the gorge; these rays are prolonged be- fore, in such a manner, that the lower ones appear to form the termination of the tongue; the opening of the gills are large, and continued almost to the in- sertion of the lower maxillary bones. According to the above character, this small fish ought apparently to be placed between the two genera 8 NEW SPECIES OF EXOCETUS. already mentioned. By the vomer furnished with small teeth it cannot apperiain to Saurus nor to Sco- peles, in which the palate and tongue are smooth. The scales are large, particularly on the sides, and to the lateral line they are higher. Pectoral fin rather large, continued parallel to the half of the dor- sal; ventral small, situated between the abdominal and the pectoral; the dorsal fin placed between the pectoral and the anal; the anal between the two dor- sal, of which the second is very small and adipose. The tail long and slender, terminated by a slightly forked fin. Eyes rather large, silvery and gilded, situated contiguous to the maxillary bones and the snout.

OxsseRVATIONS.—I have thought proper to offer some observations upon this small fish, as presenting traits of difference from the genus Saurus and Sco- peles; but I am inclined to think, that it may occur of a greater magnitude.

For the rest, the head and body is scaly, they have likewise a carina- ted longitudinal range of scales as in the Belonze and Hemiramphi, &c. The head is flattened above and at the sides ; the eyes are large, the maxillaries without pedicles and forming alone the border of the upper jaw; both jaws are furnished with small pointed teeth, and the os pharynx with teeth in pairs. They have ten rays in the gills; the natatory bladder is very-large, and the intestines straight and without coecum; the upper lobe of the caudal fin is the shortest. Their flight is never very long, and they elevate themselves in order to escape the pur- suit of voracious fish ; they immediately fall, because their wings merely serve the purpose of parachutes ; the birds also pursue them in the air, as the fish do in the water. They are found in all the temperate seas. Exocetus *fasciatus. Abdominal fins long and broad, somewhat trun- cated, scarcely attaining to the caudal; anal and dorsal, straight, low, and almost equal; pectoral fins not touching the anal; brown bands on the pectoral and ventral fins; the two first rays of the pectoral fins shorter; head destitute of beard.

Scales rather large, covering the whole body. The lateral line passes along the sides of the abdomen and touches the abdominal fins. Head flattened above, and slightly carinated to the throat. Eyes distant, at the summit of the head, large and silvery, placed obliquely. Anterior rays of the pectoral fins unequal, the three first simple, and shorter than the fourth and fifth, which are divided like the following. - Abdominal fins large, placed nearer to the tail than the head, their extremities rounded, with the first rays simple, and the others divided. The snout a little extended; the opening of the mouth much in- clined. The two individuals which I have seen, the one dried, and the other in alcohol, had lost their color, which was then brownish. It is probable that they are of the same color as the Exocetus volitans, and the individuals which I have met with in the Gulf Stream, and in our traverse from the isle of St. Croix to the United States. I saw several of the length of three or four inches, leaping before our vessel, the color of the body of which was a deep blue, with blackish spots on the fins, which appeared very transparent; but I was not sufficiently fortunate to procure any of them.

Read, December 1820. § I. THE PROBABLE LIMITS AND CHARACTER OF THE SECONDARY FORMATION. The near approach which the calcareous and other strata west of the Alleghany mountains make to the horizontal line, considering their inherent character, has been a matter of surprise to those who are any way familiar with the geology of Europe. A number of hand specimens, which some years ago I compa- red with what is called the compact mountain lime- stone of Derbyshire, in England, presented not a single dissimilar feature, either in regard to compo- sition or organic reliquie ; and I am fully satisfied, that almost every fossil and shell figured and descri- bed in the “ Petrificata Derbiensia” of Martyn are to be met with throughout the great calcareous plat- form of the Mississippi valley. We everywhere, perceive the same host of Terebratulites, Alcyo- nites, and Encrinal vertebre’; the same zoophi- VALLEY OF THE MISSISSIPPI, 45 tic casts, and vegetable impressions, likewise attend the coal formations, and it is only the difference of their elevation above the horizon which in any man- ner distinguishes the same strata in one country from those of the other. Here, however, the difference is sufficiently obvious. In Derbyshire, and in every other part of England of which I possess any know- ledge, the beds of coal are never come at by any thing like an horizontal drift; indeed, the dip of such strata is often but little inferior to that of the primitive rocks, and expensive machinery is always necessary, both to raise the coal and drain the mine. In the western states of America, on the contrary, the coal is obtamed by an almost horizontal drift, and draining becomes unnecessary. If we are then to search for any transatlantic region simi- lar in its materials and in their horizontal stratifica- tion with the extensive plains of Ohio, of Michi- — gan, Indiana, Lllinois, Kentucky, West Tennessee, and a part of the territory of Missouri, it is to be found in those extensive plains or steppes of the Tartarian desert traversed by the Kuban, which have been described by Professor Pallas and Daniel Clarke. Here, I think, we find strata of the same materials, at least, as it regards calcareous rock, abounding with fossil reliquie, and also as nearly ap- proaching the horizontal level. As we pursue, however, our enquiry concerning the western and northern limits of this great calcareous platform, through Canada, and the territories of Missouri and 16 GEOLOGICAL STRUCTURE OF THE Arkansa, we shall perceive that the same materials are also elevated into ranges of hills, dipping from the horizontal level, though still at a far inferior an- gle to that which prevails in those transatlantic countries above noticed. | In the summer of 1809, my attachment to the study of Botany, induced me to make a pedestrian tour round the greatest part of the southern shore of Lake Erie, to Detroit, from whence I proceeded in a canoe along the same coast of the Huron lake to the island of Michilimakinak, situated near its com- mencement. I then took a southwest direction along the coast ef Michigan, to Green Bay; thence to the banks of the Mississippi, by ascending Fox River, near to its source, and embarking on the Ouisconsin, which disembogues itself two miles below the vil- lage called Prairie du Chien. I then descended to the town of St. Louis. This route, and the subse- quent voyages which I made up the Missouri and Arkansa, afforded me an ample opportunity of in- struction, as to the extent and character of this vast platform of secondary formation. The coast of Lake Superior I was then prevented from examining, by the sinister regulations of the company of the north-western fur-traders. Some re- markable facts, however, concerning this lake, and the minerals of its southern coast, are detailed by the adventurous Captain Carver, and afterwards corro- horated by the relation of M‘Kenzie. Such are the accounts of the masses of native copper scattered along the shores of the bay, called Fond du Lac. VALLEY OF THE MISSISSIPPI. 17 The existence of this fact did not fail: to excite the avidity of adventurers, who were, however, disap- pointed in the pretended quantity and locality of this native metal. But although there is every reason to consider the masses of this metal, as well as others which were shown to me during this route by a chief of the Monomonies, collected near the outlet of the river St. Croix of the Mississippi, as entirely adven- titious in their relation to the surrounding strata, still even these insulated facts justify us in supposing them as strongly indicative of the approaching termi- nation of the secondary formation in this direction. We cannot yet indulge our inquiries to any advan- tage any further to the northward, as none of the other travellers in this quarter have favoured us with the smallest ray of geological information. Still we are led to suppose that the Falls of St. Anthony,* no less than the numerous portages and rapids of the Utowa river are occasioned by some con-" siderable deviation in the strata from that almost horizontal position which they otherwise present. This opinion, however, as itregards the Mississippi, amounts to nothing more than conjecture, for,.as in the beds of many other rivers, there is no possibility of deriving any information regarding the nature of its sources from the debris or gravel deposited along its banks, knowing, as we do, the wide extent of * According to the observations communicated to me by Major Long, testaceous lime-stone exists both above and below these falls. € 18 GEOLOGICAL STRUCTURE OF THE adventitious granitic gravel and bolders throughout the western states and territories. It is true, that around the Prairie du Chien, and many other places along the banks of the Mississippi, as well as those of the »issourl, and even to the berders of the Ar- kansa and Red Rivers, rounded debris occasionally appear, sufficiently distinct from any thing which we have met with either in the beds of the St. Lawrence and its lakes, or along the Ohio and its tributary streams 3 such are the different varieties of fine cal- cedony, far more resembling those of India than of Kurope, and which we term carnelian, sard, &c. as they vary in color and texture, being either red, hya- line and white, or different shades of yeilow; all these varieties, and possessing every requisite beauty for the lapidary, are to be met with im considerable abundance along the Missouri, less plentifully on the gravel bars of the Mississippi, while little more than their existence is ascertainable, along the banks of Red River and the Arkansa. ‘To what class of rocks or strata these were to be attributed, as they appear on the Mississippi and the Missouri, I never was able to ascertain; nor am [| still much better in- formed on the subject, although I have had an oppor- tunity of observing a singular granulated rock, in which they are occasionally imbedded, bassetting out from under the more recent testaceous lime-stone of Red river, about one thousand miles above its entrance into the Mississippi. My uncertainty as to the true lo- cality of these rounded chalcedonic debris, arises from VALLEY OF THE MISSISSIPPI. 44) the ambiguity inherent in all conglomerates, which merely mark the transition of one formation into that of another, and are thus almost intermediate betwixt every species of transition whether general or partial. There is, I think, reason to believe, that most of the finer chalcedonic geodes, which appear in the form of pebbles of various sizes, originate almost uniformly in those transition rocks which we term amigdaloids and conglomerates, and though porphyries, as ap- proaching more nearly to the class of rocks called - primitive, are artificially distinguished from them, there exists, in fact, no such natural precision of limit.* At all events, the presence of these chal- cedonic debris, if not more remotely adventitious, would appear to point out in this quarter, the termi- nation of the calcareous platform, somewhere below the sources of the Mississippi as well as those of the Missouri. Descending the St. Lawrence, or rather- its chain of lakes, we perceive even along the southern coast of the Huron, very intelligible indications of the ap- proaching termination of this secondary formation, in the vast beds, as I may call them, of adventitious granitic rocks, which for more than one hundred miles in succession, continue to line its shores. Many of these blocks, which are in places collected and extended into the lake for ten or twelve miles together, are of a magnitude so enormous, as to have * One or two specimens of hyaline calcedony, I once found on the gravel bars of the Missouri, imbedded in a white Jasper 20 GEOLOGICAL STRUCTURE OF THE long acquired the veneration of the Indians, and are justly considered as their perpetual land-marks. We cannot reasonably suppose that this enormous col- lection of adventitious rocks can have been very far conveyed from their original situation ; still from the existence of facts, it does not appear that the Huron lake constitutes a boundary betwixt these formations. If I mistake not, both Kalm and Carver inform us of the existence of fibrous gypsum or alabaster on the banks of the Utawas; a river, which by the aid of inconsiderable portages, affords a navigable commu- nication from Montreal to French river of lake Huron. In connection with this formation is found the softish brown-red argillaceous stone, so much esteemed and employed by the Indians in the manufacture of their pipes. By Carver, and others, it is improperly termed a serpentine, but appears to be merely a clay- stone, of which [ then obtained a specimen from the river in question. ‘There is also equal reason to cre- dit the existence of fibrous gypsum in that country, of which I received specimens during my stay at. the island of Michilimakinak. Hence it would ap- pear, that we are to search for the termination of the stratum we are tracing beyond the northern shores of the Huron, and that it in all probability ceases where the fibrous gypsum and red clay-stone commence. This calcareous platform is not even disturbed by a single elevated hill along the whole southern bor- der of lake Erie. The ridge, however, traversed by the cataract of Niagara, and the falls of Gennessee, VALLEY OF THE MISSISSIPPI. Dt: . : generally marks the termination of this stratum throughout its course, which terminates westwardly near to the proper commencement of lake Ontario. In several parts of this ridge and its vicinity gypsum has been found, as at the falls of the Gennessee, at the outlet of Owasco lake, and also contiguous to the falls of Niagara. The Table- Rock, from whence visi- tors commonly view the stupendous cataract, is in great part a mass of gypsum; which, continually moisten- ed by the falling spray and the neighbouring springs, carries down a portion of the dissolved mass, which is afterwards deposited in rounded nodules in the cavities below. In these rocks we also discover small nodules of galena and the blende ore of zinc, which is more or less prevalent throughout this ridge as far as Grand River in Upper Canada. In the dark grey gypsum of Gennessee, employed in agriculture, there exists a considerable admixture of carbonate of lime. About fifteen or twenty miles west from Queenstown this ridge presents considerable beds of calcareous breccia, or dislocated angular fragments, again col- lected and cemented in a base of the same material. Mr. Maclure traced this calcareous stratum, with its concomitant accompaniment of shells and -hornstone nodules, as far as the borders of Lake Champlain, where it terminates in the immediate vicinity of the primitive on the west, and an elongated point of the transition on the east. ‘The very imperfect knowledge which we yet pos- sess of the western regions of the Mississippi, pre-. a9 GEOLOGICAL STRUCTURE OF THE vent us in a great measure from arriving at any very satisfactory results, while pursuing our enquiries in this direction. Before entering upon this part of the subject, it is necessary to make some remarks upon the anomalies which present themselves towards the western and north-western confines of the calcareous platform. Thus, on arriving at the banks of the Ousiconsin, instead of an almost imperceptible cur- rent, as that of Fox river and its lakes, we are car- ried along at the rate of three or four miles per hour, and have almost uninterrupted hills on either bank of the river ; still there is no very considerabie dip, but sufficient to bring into view a considerably lower portion of the stratum, in which veins of galena or lead-ore begins to make their appearance. Captain Carver, and afterwards Mr. Dickson, received from the Indians a grant of these lead-mines, which Mr. Dickson informed me, promised to be no less pro- ductive than those they gave to Monsieur Dubuque, situated on the western side of the Mississippi, and about 40 miles below the entrance of the Quis- consin. The same calcareous lead-hills are met with dividing the branches of the Meremek, about thirty miles below St. Louis, and continue in a south- west direction to the sources of the river St. Francis. They are again met with on the banks of White River, and galena has also been found near the banks of Grand river of the Arkansa. ‘The first oc- currence of secondary calcareous rock on the banks of the Arkansa, is towards the hase of the arenelitic VALLEY OF THE MISSISSIPPI. 23 hills of Lee’s-creek (called Papillon, in Pike’s map) and about eight miles below the garrison of the Pot- toe. Lime-stone is found along the banks of the Salais-eau, a few miles above the former, but we no where meet with any considerable quantity of calca- reous rock, in that part of the Arkansa territory which came under my notice, excepting on the banks of Grand river, whence the garrison was supplied with lime for building. As indications of coal, how- ever, appear in this quarter, on both sides of the river, and even near the garrison, along the banks of the Pottoe, accompanied by the usual fossil reliquie, we are not to suppose that the secondary calcareous stratum is so limited in its existence in this direction, but merely covered by the sand-stone with which the occurrence of coal is concomitant. This circumstance, again, almost independent of any collateral observa- tion, points out the extraordinary approach of these strata towards the horizontal level; for, from Lee’s creek to the northern branches of the Canadian, and from thence to the great Saline river of the Paunees, a distance, over land, of near 300 miles, on the southern side of the Arkansa, we were never able to discover a solitary specimen of calcareous. rock, be- ing every where covered by the sand-stone, and in no place presenting a derangement or dip sufficient to be exposed from beneath. [It is almost unneces- sary to add, that a country like this, presents little else than one uniform plain, in general destitute of arborescent vegetation, and that it is also very defi- 94 GEOLOGICAL STRUCTURE OF THE cient in springs of water. While on the contrary, the calcareous country of the Salaiseau, of Grand- river, of the [llinois, of Arkansa, and also the undu- lated arenelitic lands towards the borders of the great Saline river, abound in springs, that continue to flow throughout the hottest months of the summer, and produce around them morasses, which from their de- ceiving depth, are dangerous to the approach of the larger quadrupeds. While ascending the Missouri in the summer of 1810, I could not ascertain the existence of the com- pact calcareous rock, containing organic reliquie, beyond the confluence of the river Platte; yet the sand-stone hills, and woodless plains, in the rear of the Maha village, were precisely such as we met with along the northern borders of the Arkansa, within the limits of Pottoe, and the Saline rivers. In the ter- ritory of Arkansa we could no where distinctly ascer- tain the existence of those more ancient and deep beds of uniform argillaceous matter whichso often along the banks of the Missouri, bury out of sight the inferior rocky stratum, in such a manner, as at length entirely to conceal its character. This clay formation, en- tirely unconnected with that of the Mississippi, and the lower part of the Arkansa, is of a blueish-grey, abounding in pyrites and xylanthrax, and is the active seat of those pseudo-volcanoes and their re- mains existing in the upper part of the Missouri ter- ritory. Excepting wood, even whole trunks of trees, in every state of siliceous penetration and petrifac- tion, a fossil Ostrea or mya, and what my friend Mr. VALLEY OF THE MISSISSIPPI. OH: Thomas Say considered as an unknown species of baculite,* no other organic remains were noticed by us in this vast deposition of argillaceous matter, which often appeared near the bank of the river in black- ened sterile hills and cliffs of from two to three hun- dred feet elevation. It is highly probable that the fossil crocodile skeleton, or proteasaurus, mention- ed by Lewis and Clarke, was deposited in this argil- laceous bed, although I once found, on the loftiest summits of the gravel hills of White River of the Missouri, several fragments of large fossil bones, apparently vertebre, accompanied by some eburneous process partly transformed into silex. The calcareous cliffs which border the Missouri, not far from the creek of the Maha village, more closely resembled chalk than any thing of the kind which I have heretofore seen or heard of in North America, but cannot by any means be identified with the same formation in the south of England and in France. We could not discover in it any organic reliquiz, nor any vestiges of flint. It is, neverthe- less, sufficiently white, meagre, and absyrbent, when. moistened, and marks with facility. Connected ap- parently with this anomalous formation of chalk, we observed considerable beds of what appeared to be stalactitial gypsum, but whether a more general de- * Published in Silliman’s Journal. vol.

D 26 GEOLOGICAL STRUCTURE OF THE position, or a mere adventitious production formed by the partial agency of the decomposed pyrites so prevalent in the argillaceous bed above noticed, I am not prepared to ascertain. It occurred in seams, though divided into small and rounded masses, per- fectly white, but so devoid of the fibrous structure as {o be readily confounded with the chalk. The si- milarity of this secondary calcareous formation on its opposite confines in East Tennessee, as it appears immediately after crossing the Cumberland gap is deserving of attention; here again the calcareous rock puts on the appearance of chalk, and even con- tains nodules of flint, but bordering too much on chal- cedony to afford the character requisite for economi- cal purposes. Before taking leave of this part of our subject, and indeed not unconnected with it, is the anomalous de- position of salt, and the preduction of nitre. We all know that the impure nitre of the western states, of which the greatest abundance has been found in the neighbourhood of the Cumberland ridge of mountains on the confines of East Tennessee, is always connect- ed with the caverns of calcareous and arenilitic rocky. and that it is not an accidental! production, arising from the decomposition of animal and vegetable matter, is indeed proved by its gradual renewal in those caverns which have been exhausted. As 1 have been inform- ed, it exists in the calcareous and sandstone recks which are consequently attacked by the humidity of the air, and so falls into earthy fragments, which are VALLEY OF THE MISSISSIPPI. QF collected for lixiviation, and that the solid stone it- self is also occasionally broken and submitted to the same process. I am not acquainted with the existence of many localities of nitre on the west side of the Mississippi, though it has been obtained in considera- ble quantity along the banks of the Meremek, and some of the streams emptying into the lower part of the Missouri. The Hirandel rocks on the banks of the Arkansa possess the only appearance of affording nitre which f have seen in that territory. { have termed the production of salt in this forma- tion as anomalous, regarding any connection which it bears with the ordinary gypseous or red-clay forma- tion of the European geologists. No doubt numerous yemarks have been made upon this subject, which I now merely examine as a matter of fact. Every one knows the abundance of salt springs which exist in the valley of the Ohio and its tributary branches. The most productive among them are the springs of the Kenhaway and the Big Bone Lick. Those of Onondago Lake, in the western part of the state of New-York, are no less important. In my enquiries and personal examinations, I must confess myself to be generally at a loss to ascertain the proper ori- gin of these springs. In no instance is this salt met with ina solid form, nor in distinct connection with gypsum, or with red coloured clays. The argilla- ceous soils, indeed, which do occur, are dark gray or grayish blue. At the Big Bone or Mammoth Lick on the Ohio, and in many other places, where ve ‘ 28 GEOLOGIEGAL STRUCTURE @F THE fossil bones have been found in their immediate neighbourhood, we should have been led to suppose these springs to be in connection with ancient alluvial deposits; while on the other hand, where the boring and obtaining of salt water has been continued through beds of coal and of limestone for some hun- dreds of feet, every idea of alluvial origin must va- nish, and we are led to consider the existence of these saline springs as coeval with the strata in which they originate, in common with the nitre, the petroleum, and the coal. ‘The occurrence of those remains of extinct quadrupeds which are found in their vicinity, may be considered as accidental, or merely connected with their relish for sait.* The extent of these salt springs is nearly as wide as that of the secondary rocks which they accompa- ny: thus they are found in several places along the banks of the Mississippi, from the Prairie du Chien to the confluence of the Ohio, wherever the: intersec- tion of streams have afforded them an outlet. They occur along the banks of the Meremek near to St. Louis, and along the Missouri to the Osage river ; they are met with on the banks of this river almost to its sources; they reappear along the borders of = * These relics are the bones of the common mammoth or mastodon of the Ohio, the Siberian elephant, or true mam- moth, teeth of the rhinoceros, and in the caves have been found the bones of the megatherium, a very fine collection of which were in the cabinet of the late Mr, Clifford of Lexington. VALLEY OF THE MISSISSIPPI. 25 Grand River of the Arkansa, fifty miles up which river, one of the principal springs is now worked. This place [ have carefully examined. Here the springs, which are uncommonly clear, strong, and copious, distinctly and immediately issue through a bed of calcareous rock, and are accompanied by a stream of sulphuretted hydrogen gas, but occasion- ing only a minute deposition of sulphur. Other springs, equally productive, likewise occur in the distance of twenty-five miles further up this stream. The Cherokees have discovered springs of salt wa- ter on the banks of the Ilmois of Arkansa, but in this quarter as well as on the banks of Grand River, they do not happen to be accompanied by any re- mains of quadrupeds. Unconnected with this soil and strata, though scarcely with our subject, is the gypseous Red Clay formation, and the salt which it affords. Of the ex- istence of ‘this salt formation towards the sources of Red River, there is the most unequivocal evidence ; it is the abundance of this mineral, independent of that of the calcareous stratum, which so frequently communicates, particularly in the inundation of the Red water, a sensible brackishness to the whole stream of the Arkansa, and occasions its water to be preferred by all the wild and domestic animals. In- deed, in dry seasons, like that of the last autumn, (1819) a saline efflorescence was sufficiently visible over all its argillaceous deposits. The locality of this red clay soil is sufficiently attested by a slight 38 GEOLOGIEAL STRUCTURE OF PHE attention to the color of the streams which empty inte the Arkansa; thus, all the rivers which enter from the north or north-west, bring down either water which is clear, or rendered turbid with grey colored earths and clays, while on the opposite side come in a number of streams which are charged with turbid water, always of a reddish brown color. Such are the Canadian, and the three Saline rivers, whose waters, except that of the former, are at all times im- potably saline. Still further tracing the locality of this production, we find that the red water of the Ca- nadian is the produce of its main southern branches, which all the hunters and traders assert to derive their sources with the head waters of Red river, and the Spaniards inform us, as a well known matter of fact, that Red river originates in the mountains of Santa Fe, of Rio del Norte. The northern branch of. the Canadian is said to proceed almost parallel with ihe Arkansa, and possesses clear water in common with its tributary the lesser North river, which sources in the immediate vicinity of the Arkansa, and makes a very near appreach to the great Saline river of the Paunees, already mentioned. It is in the im- ‘mediate neighbourhood of the second river of Saline water, that Dr. Sibley was conducted by the Osages. . to what are commonly called the salt plains, where ihis mineral appears in place, and lies scattered over the surface of the ground.

Krom three experienced hunters who had spent a great part of their lives in this country, and pene- trated to the western mountains, I received accounts. of the prevalence of a mineral towards the sources of Red river, which, on producing specimens, timed out to be fibrous gypsum, similar to that of the Utawah river, in Upper Canada; it was said to be very abundant and continuous in its appearance. My guide, Mr. Lee, first observed it on the banks of what the French call the False Washita, one of the prin- . cipal northern branches of Red river. A river of saline water too brackish to drink, as I was informed, enters the river Platte from the south, about thirty miles above its confluence with the Missouri. ‘The Sioux river entering the Missouri from the north, according to the report of the interpreter (Dorion) who accompanied us in cur voyage up the Missouri, im 1810, informed us, that this river sources with the St. Peters, and after remaining navigable for upwards of two hundred miles, is then obstructed by a cataract. and that below the falls a creek enters from the eastward, after passing the cliffs of the red clay-stone employed by the Indians in the fabrication of their pipes. From what we can glean concerning this principal formation of salt and gypsum, it would appear to be situated in the vicinity of the primitive mountains, 32 GEOLOGICAL STRUCTURE OF THE and at all events marks the termination of the se- eondary soil. ; The fluate of lime, so abundant and beautiful in the secondary calcareous rock of Derbyshire, in England, is not altogether wanting in the valley of the Mississippi. In 1810, Mr. J. Bradbury favoured me with very fine specimens of white, blue, and am- ber colored fluor, from a lead mine, at the Rock and Cave, in the vicinity of the Ohio. Another lo- . cality of this mineral was pointed out to me, also in 1818, as existing near Centreville, in the county of Logan, in Kentucky. In the same locality with that described by Mr. Bradbury, Mr. Jessup found it in abundance on the surface for a space of thirty miles, accompanied by a vein of galena. In its vicinity, Mr. J. also met with nodules of argillaceous iron ore, containing blende. But fluor has never yet been found on the banks of Missouri, as. assert- ed by Mr. Claiborne. The floetz trap formation, or that variety of it, termed in Derbyshire, toad-stone, and which there so signally deranges the strata and metalliferous de- posits, in no form makes its appearance throughout this secondary platform, the only anomalous bed in any manner analogous to this, is the greenish, and apparently ferruginous arenilitic rock, with a sparry calcareous cement, and bordering on graawacke, which appears beneath the newer floetz lime-stone of Red River. VALLEY OF THE MISSISSIPPI. 33 Having thus taken a cursory, but imperfect view ef the great tabular formation of secondary calca- reous rock, which gives place to the immense plains and lakes of the western states and territories, we shall next proceed to offer a few remarks upon the ancient maritime alluvium, and a fletz formation apparently connected with it, which continues from Rhode Island to the coast of the Gulf of Mexico, . principally with a view to ascertain its south-west- ern limits, and to observe the influence which it has had in producing the present character of that part of the Mississippi valley. The accurate and com- prehensive view of this formation, as well as of all the others composing the North American continent, by our absent president,* the result of observa- tions continued for many years in succession, leaves us little more to do than corroborate his assertions by additional details, and an extension of its limits into the remoter territories of the Union. § II. LIMITS AND CHARACTER OF THE ANCIENT MARITIME ALLUVIUM. The extent of the primeval ocean, and the vast agency which it has exercised over our globe, to ren- der it habitable, and thus to complete the plan of creation, is evinced by a vast proportion of its sur- face wherever our observations are directed. That * William Maclure, Esq. 34 GEOLOGICAL STRUCTURE OF THE immense portion of the valley of the Mississippi, over which we have in the preceding section rapidly glanced, without entering into details, exhibits throughout all its extent unequivocal marks of a pelegian origin, its rocks are filled with marine pro- ductions. with bivalve shells, with Alcyonites, En- crinites, Madrepores, Millepores, Tubiporites, F'lus- tras, Trilobites, some species of Ammonites, Zoe- phytes, &c. &c. of which by far the greater part are now extinct, having disappeared with the ocean that gave them birth: indeed, several of their genera no longer possess any existing type. ‘The antiquity of this order of things, apparently anterior to the crea« tion of any other organized beings, is beyond our comprehension ; what occasioned the reflux and sub- sidence of these mighty waters, and the consequent elevation of the land, is a subject equally imvolved in mystery. It is sufficient for us to mark the different epochs of this reflux, so as to connect our remarks, and render them intelligible to those who wish to follow us in the course of ebserva- ‘tion. Tes The pelagian calcareous rock which occupied our altention in the preceding section, and which” may correctly be termed a compact limestone, pre- sents to our view scarcely any of those shells and marine productions still existing in the present ocean. ‘They are almost without exception bivalves, among which the terebratulites continually predominate.

It is greatly to the advantage of the miner and the mineralogist, as well as to seve- ral branches of public economy, that such geo- logical distinctions could be drawn betwixt the dif- ferent strata and formations of minerals, as might al- ways prevent the waste of money and labour. Yet, after all, it is to be regretted, that the ambiguity of certain strata is sometimes so great, as to adinit of considerable argument in ascertaining their differ- _ ence; such, in a great measure, is the character of the second’ calcareous formation which now claims our attention. In its geographical limits, it occupies a position universally to the east of the primitive and transivion formations. Its existence, as far as I know,. has not been ascertained to the north of the bay ef Chesa- peake; it here makes its appearance in the vicinity of Annapolis, and presents several features common to the transmontane stratum. It appears, however, to be destitute of the concomitant minerals, except- ing, indeed, it were possible to conceive i in con- nexion with the coal basins of Richmond, which F have found on examination to be actually underlaid with a calcareous rock of a peculiar appearance. Mr. Heath’s coal-mines, and, in fact, nearly all of them, except those which were in a state of combus- 36 GEOLOGICAL STRUCTURE OF THE tion, are overlaid by a massive micaceous conglome- raie, or grit rock, containing crystals of felspar like ‘porphyry, in which, besides gigantic culmarii,* oc- cur veins of the argentine calcareous spar of Kir- wan, similar to that of Cornwall, resembling silvery talc or steatite, in which are occasionally imbedded minute chrystals of blue and white fluor like those, - equally rare, in the gneiss of the Schuylkill, together with common calcareous spar and chrystals of sul- phate of lime. In the bituminous slate clay, which, as usual, accompanies this coal, besides impressions of ferns, and the supposed Equiseta, there are vesti- ges of some enormous flaccid leaved gramineous plant, leaves of one of the Scitaminee similar toe those of ginger, and fine casts of a palm, resembling the pennate fronds. of some species of Zamia, or Cycas. The apparent remains of fish, which alse occur together in such uncommon abundance, are ex- tremely ambiguous, inasmuch as the supposed fins alone, are found. ‘The coal in this formation, instead of that even continuity so obvious in that of the west- ern states, presents very limited beds, which, as they yecede or occupy the centre of the basin, vary from 6 or 8, to that of 40 feet in thickness! The coal itself, highly bituminous and brittle, contains abun-— - dance of pyrites. What relation the breccias and * An assumed generic name for an assemblage of extinct Zoophytes?

On the high road to Richmond, in the exposed declivity: of the barren pine-hills, a few miles from the coal- mines, [ found fragments of transformed wood, pe-: netrated with quartz of an opaque white color, des- titute of the resinous fracture, and easily crumbling into an almost impalpable sand. These fragments, however, occurring in beds of disintegrated, and amorphous chrystalline quartz, in which also appears the oldest conglomerate* of cloudy and pale blue quartz, are more probably referable to the an- cient beds of the transition. Of the small impor- tance, however, which ought to be attached to the relative antiquity of transition rocks, and particu- larly to those which are so evidently mechanical in their structure as the conglomerates and sand-stones, we have an almost unexpected example, in the re- cent discovery of bones imbedded in the old red sand-stone of New-Haven, 35 feet below the surface ; a circumstance, in itself, sufficiently curious, without introducing the improbable conjecture of the remains being human. _ * As it regards the strata of the United States, and always eecurring from the state of New York to Georgia, imbedded in the mica-slate. 38 GEOLOGICAL STRUCTURE OF THE - Although, there can remain but little doubt of the continuity of the floetz lime-stone we are endeavour- ing to trace towards the south, still, in consequence of the more recent alluvial deposits, it is not again discernable until we arrive in North Carolina. Here, Mr. Maclure remarks, that it runs “ parallel to, and within the distance of-from 20 to 30: miles of the edge of tae primitive, through South Carolina, Geor- gia, and part of the Mississippi territory.” That it continnes also eastwardly to the borders of the ocean, I have reason to believe, from discovering it in the immediate vicinity of Wilmington, North Carolina, where it appears from beneath the alluvial sand-hills of the town. There, though less compact than the older secondary formation, it alike contains terebra- iulits, flustras, millepores, caryophylites, gorgonias, as well as more recent shells, such as cardiums, pec- tinites and ostreas, not very dissimilar to the exist-— ing species of the coast. In 1816, while proceeding through North and South Carolina, to the city of Charleston, 1 remarked the first appearance of this floeiz lime-stone in the immediate neighbourhood of Statesburgh, in South Carclina, near the commence- ment of the hills of Santee. Here we observe a fine- grained slaty and ferruginous sand-stone, containing scales of mica, and rounded nodules of argillaceous iron-ore, basseting out from beneath a conglomerate made up of sea-shells and quartzose pebbles, cemented together with calcareous, as well as siliceous maiter, the latter of which often appearing in the form . VALLEY OF THE MISSISSIPPI. 39 of hotryoidal agate. These marigenous beds are nearly horizontal, though here elevated into hills, and appear. as far as I could previously observe from anulogy, to be underlaid by a formation of trap and argillite. Krom hence, to the little town of Man- chester, there imfervenes a succession of coarse- grained and ferruginous sand-stone hills, washed into deep gullies, presenting a prevalence of red and very sandy clay, indicative of the decomposed: trap. Kighty miles from Charleston. along what is called the river-road, on the high and sandy banks of the stream produced by the Drowning Spring, I noticed scattered masses,of a stone, consisting in great part of flinty confluent silex, bordering on chalcedony, including seams of broken shells, as well as others which were imbedded and retained their calcareous substance. Some of them were spiral univalves, ethers cardiums, and pectinites resembling those of the present sea-coast. In some places this stone ap- pears to pass into a granulated quartz, resembling sand-stone, but of a very fine and drusy grain. This bed appeared to he about twelve inches in thick- ness, and sensibly compressed; beneath, it passes Into a sand-stone, which is again underlaid by a thick bed of light grey schistose and indurated mar- lite, containing also rounded nodules of the same substance. The Utaw spring is one of those large bodies of clear water which issue at once in consi- siderable streams from the bosom of this stratum. This formation is considerably allied to the siliceous 40 GEOLOGICAL STRUCTURE 6F THE X\ lime-stone of the environs of Paris, and mill-stones have been made of it, but are found to be softer than those of France. In its seams have also been dis- covered depositions of hyalite, or the concretionary hyaline quartz of Hauy. At Nelson’s Ferry, on the south side of the San- tee, I again observed an horizontal ledge of the floetz lime-stone, of a whitish color, and fragile consistence, containing amidst innumerable masses of small shells, those of some Osirea, not very dissimilar to existing species, but of a remarkable thickness, and occasion- ally impressed with the forms of other shells. The copious and clear springs of this formation continue to within ten miles of the city of Charleston, where, with its overlay of ferruginous sand-stone. it forms the feundation of all the other alluvial deposits. Amorphous carbonaceous remains, connected pro- bably with lignite, sparingly appear in this soft sand-stone a few miles from Charleston. In a for- mer route, from Savannah'‘and Augusta, in Georgia, I repeatedly met with this calcareous bed, in which even occurs the trilobites paradoxus, and the ovate encrinal fossil, figured by Parkinson and described by Mr. Say in Silliman’s Journal, .under the name of Pentremite, hitherto found only in North America, and in connection probably with this for- mation.* In some parts of South Carolina, this calcareous rock appears of a friable texture, and > * This curious fossil occurs also, abundantly in the lime~ stone of Huntsville, in the Mississippi territory.

Its existence has been traced into part of the Missis- sippi territory,* and again found along the coast of Cape Florida, and the gulf of Mexico, by Mr. Ma- clure. Along the banks of the Mississippi, and towards the base of the hills of Fort Adams, it again presents its usual characteristics, being of a whitish color, of a soft and friable consistence, like calcareous tufa, and also in connection with an undurated marl. Ascending this river, without discovering its exist- ence decisively in the alluvial hills of Natchez, we, however, perceive its arenilitic'overlay in the basis of the cliffs known by the name of the Grand and Petit Gulf, where the obstruction of this stratum suddenly checks the meanders of the river, and produces two very powerful and dangerous eddies. ‘The last ap- pearance of this stratum on the banks of the Missis- sippi, as indicated by sand-stone, is in the bases of what are called the Walnut-hills, but its concomitant marigenous alluvium can be distinctly traced 10 the ferruginous cliffs, called the Paint-hills, or Mine au Fer, about 15 miles below the confluence of the Ohio; indeed Henderson, or the Red Banks, and the town * Marine shells, as Ostreas, &c. have been found at the “ Chickasaw Old Town,” 300 miles north-east of Natchez, as well as at the United States agency amongst the Choctaws, 120 miles north north-east of the same place, according to Mr. E. Cornelius, in Silliman’s Journal. B 42 GEOLOGICAL STRUCTURE OF THE of Owensville, commonly called the Yellow banks, the latter about 120 miles below Louisville on the Ohio, still present traces of this extensive deposition, though unaccompanied by the sand-stone and calca- reous rock. On the west side of the Mississippi we also discover the same marine alluvial formation in ‘the elevated banks of the Arkansa, on which the town of Arkansas is situated, and which terminates the great prairie, dividing the waters of this and the White rivers. Still more lofty, and better cha- racterized, are also the friable cliffs, called the Pine- bluffs, commencing about 120 miles higher up this ri- ver. Proceeding from hence in a southern direction, we again meet with this alluvium on the banks of the Washita, which gives rise to the Bovey-coal or lig- nite mentioned in the voyage of Dr. Hunter and. Mr. Dunbar. In the calcareous platform of Red River, which we found to constitute the basis of its. plains, both above and below the confiuence of the Kiamesha, we discover a great extention of this formation to the west, and in some degree parallel with the indention of the Mexican Gulf. This limestone presents all - the usual characters of friability, whiteness, argilla- ceous admixture, and more recent shells such as cardiums, pectinites and ostreas, as well as gry- phites, terebratulites, and alcyonites. In a few places along the immediate banks of Red River, it is partially overlaid by hillocks of a conglomerate abounding in horn-stone and other siliceous pebbles, cemented principally by ferruginous matter. A more VALLEY OF THE MISSISSIPPI. 45 remarkable aggregation, appears, by a dip, to basset out from beneath this calcareous platform, on the northern banks of the river, near the entrance of the Kiamesha. From its massive appearance, and ob- scure greenish-grey color, it strongly resembled a — trap, or grauwacke; it proved, however to be a calca- , reous sand-stone, with a crystaline cement, and like the grauwacke, as well as sand, occasionally includes adventitious pebbles, and angular debris, among which we observed the existence of chalcedony. How far this calcareous formation extends into the neighbouring province of Texas, and under what cir- cumstances, I have not been able to ascertain; but I may further add, concerning its north-western limits, that it appears to be essentially separated from the older secondary calcareous formation, by the inierpo- sition of a transition range of mountains, stretching ‘towards the south-west, which separate the tributary streams of the Arkansa from those which flew into Red River; and that from hence to the gulf of Mex- ‘ico in a south-east direction, traversing the plains of Opelousas and Attakapa and the maritime part of the province of Texas, no other chain of mountains are known to exist. Itis not necessary for us to trace the maritime alluviumof the Atlantic statesso well de- fined in the essay of Mr. Maclure, and we shall now merely add some remarks on its character as it ap- pears in the valley of the Mississippi. Along the immediate banks of this river, it is no where inter- sected on its western border; all the cliffs of reenter- 44 GEOLOGICAL STRUCTURE OF THE ing high-land are confined to its eastern bank. The first of these, below the mouth of the Ohio, is the Mine au Fer or Iron-banks; and after a descent of several hundred miles, we again perceive an occur- rence Of the'same bank of friable materials in the four successive bluffs or cliffs of the Chicasaws. As this alluvium is here best developed, we shall attempt to describe its appearance. ‘These cliffs are elevated about 250 or 300 feet above the lower level of the river, and are a portion of the continuous high-lands which constitute the principal part of the territory. They are connected with the uplands of the Walnut- hills, of Natchez, Fort Adams, Grand and Petit Gulf, Ellis’s and Thomson’s cliffs, and finally ter- minate a few miles below Baton-rouge. The surface often presents a ferruginous clay or gravel ; and from the deep and friable nature of the materials, it is sub- ject in the vicinity of streams to be washed into deep and wide ravines. The soil is but moderately fertile, and requires .the aid of manures. The Chicasaw Bluffs, which from top to bottom, as well as at Nat- chez, present nothing but friable beds immediately below the surface, consist of sandy and ferruginous clays, lower down often purer and whiter; then suc- ceeds, with an almost unexpected uniformity, a band of bright pink-colored clay, which we also recognize at the Mine au Fer, as well as in the Pine-bluffs, about 180 miles up the Arkansa. ‘This clay is suc- ceeded by another bed nearly similar to the first; a carbonaceous appearance then succeeds, and com- VALLEY OF THE MISSISSIPPI. f 45 monly a thin bed of lignite ; dark, greyish clays still follow, containing pyrites, and argillaceous iron ore, often lying at the base of the cliffs in corroded, flat- tened, and rounded masses; and at the very lowest level of the river, in low water, a second and much thicker bed of lignite succeeds, exhibiting every gra- dation from the state of wood, and also containing, amidst more friable materials, indurated sand-stone nodules, resembling those of argillaceous iron-ore, containing impressions of the leaves of existing oaks* as well as those of plants resembling species of Equi- sefum. We have to ascend the Arkansa 60 miles from its © outlet, through the recent alluvium, before we arrive at the commencement of the primitive soil. All the inferior space intervening betwixt the Mississippi, and White River, is so subjeet to inundation as to be rendered totally ith Habitable: How far the sup- posed ancient marine deposit extends into the Great Prairie, which is about 90 miles i in length, I have not been able satisfactorily to ascertain, though from the | extent of adventitious gravel over the neighbouring uplands, and the reappearance of its bed in the Pine- bluffs, 120 miles above Arkansas, we have no reason to suppose its termination short of the whole extent of the prairie. Amongst the least equivocal marks of ma- rine origin visible in this deposition, is the discovery * Such as those of Quercus phellos the Willow Oak and @. rubra or Q. coccinea the Red Oak. 46 GEOLOGICAL STRUCTURE OF ‘THE of shells, which accidentally came to my notice a few miles below the Pine-bluffs, picked up by the chil- dren of some of the French hunters resident in this country, and consisting of a species of ostrea, like that of the Santee, penetrated by seams of calcareous crystals, exhibiting marks of a former attachment to a softish ferruginous sand-stone, and containing frag- ments of lignite. On the same sand-bar was also found a small conch-shell,* which did not appear to have been imbedded. This massive deposit, in all probability, rakes an appearance at Alexandria on Red River, to which place the recent alluvium also extends; and the fer- ruginous conglomerate resembling that of New Jer- sey we have found to continue more than 1000 miles up this river. From a consideration of these circum- stances, and the direction of the transition chain of mountains, which traverse this territory. nearly from north-east to south-west, we are led to suppose the ex- istence of the more recent calcareous platform nearly to the sources of Red River, where it is probably suc- ceeded by the gypseous red clay and salt formation. The extraordinary breadth of that part of the al- luvial valley of the Mississippi, subject to inundation, from the mouth of the Ohio to the ocean, said to be of the extent of from 30 to 40 miles, is easily account- ed for, in the friable nature, and the magnitude of the marigenous deposit through which it fiows. Its bed : a ne A tet te eee * Strombus pugilis. VALLEY OF THE MISSISSIPPI, 47 appears continually to have encroached towards the east; and indeed all the larger rivers, except the Ohio, come in from the west, and possess currents considerably more rapid than that of the Ohio.* From a point, a few miles below Baton-rouge, © where the primitive soil terminates, we are to trace the commencement of the proper delta, or modern al- juvial formation of the Mississippi. From hence the river presents no more sinuous meanders; but, with- ' out any additional breadth, proceeds towards the ocean in flexuous lines ‘or stretches, disembogues much of its waters by receding channels or bayous, _ aud presents along its banks, which are of an uni- form and depressed elevation, a conformity of surface incompatible with the caprice of any formation of in- dependent origin. For several hundreds of miles in succession, to the city of New Orleans, no settlements are practicable beyond the border of the river; the agricultural plots, all defended in front from inunda- tion, by a levee or continued line of embankment, are constantly averaged at a depth of 45 arpens or acres, beyond which universally commences an undrainable swamp. The fertility of these lands is no where ex- ceeded, and without any kind of tillage, promise a’ perpetual harvest, and never-fajling source of wealth to the planter. * According to the observations of Major Long, the descent | of the Ohio is 8 inches per mile, that of the Mississippi 12, that of the Missouri and Arkansa 16, and of the river Platte 18 inches, 45 GEOLOGICAL STRUCTURE OF THE We shall now conclude this essay by a few re- marks on the transition chain of mountains which traverse the Arkansa territory. § III. opseRVATIONS ,ON THE TRANSITION MOUN- TAINS @F ARKANSA. The first appearance of this formation, as well as the first rock which attracts our attention in ascend- ing the Arkansa, commences about 200 miles above the village or post of Arkansas. From the unusual appearance, and inconsiderable comparative eleva- tion which the hills here present, the place has re- ceived the name of the Little Rock. The strata which are schistose and destitute of organic reliquiz, dip at an angle of more than 45° to the north-east, and consist of dark-grey, or greenish-grey, argillaceous sand- stone, of a fine grain, and intermingled with mica; it appears to be a grauwacke slate, bordering on argillite, and is traversed by massive veins of quartz containing crystals. Itis here alternated with a soft and pale coloured slate clay, which decomposes into something resembling pipe-clay, and which the inha- iants have employed for white-washing the interior of their cabins. As we proceeded westward, those hills at length assumed the elevation of mountains. being schistose towards the base, and. arenilitic at the summit. "The sand-stone of a coarse grain, light- ish grey color, and lesser dip, is likewise destitute of organic remains. At Piatt’s settlement, we came in full view of a conic topped mountain, rising not: less than one thousand feet above the neighbouring VALLEY OF THE MISSISSIPPI. 49 plain. At first view it appeared to be insulated, but was actually connected with an adjoining ridge of inferior elevation. ‘This mountain, resembling a py- ramid, is known fo the French and Diener resi- dents and hunters, by the name of the Mammelle. It was distinctly visible from the hills of the Dardenai, a distance of more than 60 miles over land. From the same point of view, we could enumerate three principal ranges of mountains tending towards the south-west.* . In several places the schistose strata are almost vertically elevated, so as to present along the margin of the river, a smooth and even wall, occasionally pe- netrated with zig-zag seams of quartz. At the Ca- dron, three hundred miles from Arkansas, the slate exposes to view impressions of something related to the ramified Alcyonites, but fleruous and spirally grooved, also concave articulations of a species of Or- * The mountain, apparently laid down in Pike’s map as visible at the distance of three days journey, is situated about ten miles south of the Illinois bayou, and is a long ridged emi- nence, known to the French by the name of the Magazin mountain, connected with a chain which proceeds to the sources of the Pottoe, the Petit John, Le Fevre’s fork, and the Kiamesha of Red river; from hence; without ever touching Red river, the mountains proceed towards the sources of L’eau _ Bleu, and the Faux Washita, continuing in a direction towards the head springs of Red river, where they Esa y coalesce with the primitive range.

I shall therefore, in reference to its prevailing color, give it the trivial name of GALACTITE. : This siliceous mineral, which in many respects resembles Hornstone or Chert, is distinguished by its remarkably even; slaty cleavage both in the large masses and minute fragments; its cross fracture is largely conchoidal, and destitute of lustre; fragments, about a line in thickness, are strongly translucent. Its hardness is such, when pure, as readily to give fire with ~ VALLEY OF THE MISSISSIPPI. 54 ‘bouring mountains of the hot springs, which originate in tuis formation, I have seen.specimens of magnetic iron-ore, like that of the Hudson and New Jersey. On the road to the springs, also, L have obtained spe- cimens of a dark grey amphibolic rock, strongly magnetic. when heated, of a very close grain, steel. Its color, very similar to that of Cacholong or porce- fain, is milk-white, acquiring a faint ferruginous tinge by ex- posure to the weather, it then more readily cleaves, and beconies somewhat absorbent. Its specific gravity is 2,60. Before the ' blow-pipe it is perfectly infusible, and unlike chalcedony and flint still retains its translucence. With potash it dissolves into a white enamel, but does not form glass. Analyzed in the manner described by Klaproth, which it is not here neces- sary to repeat, it afforded in the hundred parts, silex 86, alumine 1,50, lime 2, oxid of iron 5, and volatile matter with a trace of carbonic acid 4. Geological situation and locality.| It is found in the transi- tion mountains of the Washita, a few miles from the hot- springs, and in the Mazern mountains, at the sources of the Kiamesha of Red river, forming schistose beds, which alternate with slate-clay and grauwacke-slate. Passing apparently into a translucent hornstone, still retaining the slaty cleavage, and often breaking into rhombic fragments, similar to felspar. This mineral is the ‘“ hone-stone,” spoken of by Hunter and Dunbar, but sufficiently distinct from Novaculite, although when weathered or deteriorated by foreign admixture, it be- comes in some degree, suitable for that purpose. Its cleavage appears to be produced by the iron, which it essentially contains, and its milky color is probably derived from the carbonate of lime. 52 HENTZ ON A NEW SPECIES and containing imbedded prismatic chrystals of brown mica. Slate of various kinds, occasionally alternating with a peculiar novaculite border.ng on . hornstone, and dipping at an angle of not less than 45 constitutes the principal part of this formation, and is overtopped as in the Alleghanys, by elevated ridges of sand-stone.* * In this chain of mountains, which continues north-east- ward towards the sources of the St. Francis, two miles north of the village of St. Michael, at the lead-mine of La Motte, Mr. Schooleraft observed, what he calls a vein of granitic rock, of a red color, and containing very little mica, he asserts it to be four or five miles wide, and traced its continuance for twenty or thirty miles; as he adds, at the same time; that it is used for mill-stones, I can scarcely doubt for a moment, its - identity with the transition conglomerate which Mr. Bradbury and myself examined, in 1810, employed for the same purpose, a few miles from St. Louis. What the green-stone porphyry may really be, I cannot pretend to say, though it may very pos- sibly exist in that quarter. Mr. Bradbury visited the spot and obtained specimens of the micaceous iron-ore, which is said to form a mountain mass near to Bellevue (Washington county.) These united facts, tend to prove the continuation of the tran- sition chain of mountains beyond the valley of the Mississippi, but they ought not to be confounded with the chrystalline gra- nitic formation of the sea-coast and the northern Andes. OF AMERICAN SPIDER. 53 A Notice concerning the Spider, whose webb is used | in medicine. By N. M. Henrz. It has been found lately, that the webb of a species of spider, common in the cellars of this country, pos- Sesses very narcotic powers, and it has been admi- nistered apparently with success in some cases of fevers. . Having for some time past, studied with care, the genus Aranea of Linneus, I have been induced to write a description of this species; I therefore made a drawing taken from a large female, which accompa- nies the present notice. The genus Aranea of the first writers on Entomo- Jogy being composed of a very great number of spe- cies, it has been found necessary to divide it into smal- ler sections, or families. Gmelins’ edition of Linneus contains ninety. eight species; W alckenaer ennmerates nearly. three hundred, and the number may be carried. toa thousand. If the colour of the abdomen were the only character to find the species among several hundreds, it would be a very difficult task to assign with certainty a name to each separately, without any other description. Messrs. Latreille and Walck- enaer have rendered the history of this genus quite easy to study: they have left little undone in regard to the species known to them. It is to. be regretted that Mr. Walckenaer’s Tableau des a is not a more common work. I shall therefore give the generic characters of 54 HENTZ ON A NEW SPECIES this spider, as if the work was unknown to the natu- ralists in this country. 5 3 It belongs to the genus Tegeneria of Walckenaer, and to that of spiders, properly so called, of Latreille. Its characters are: eight eyes, farming two parallel lines, the upper being curved aad longer. Lip wider in the middle, cut straight .at its extremity. Max- iz inserted upright, not bent on the lip. Corselet nearly as large as the abdomen. The first pair of legs the longest, the fourth next, then the second, and the third the shortest. Manners, spiders form- ing an horizontal web, with a Eey lindrical tube, in the form of a funnel. ; This is sufficient to characterise the genus, contain- ing ‘the different species of spiders, which inhabit cellars and dark places. The species that makes its web in the fields, on bushes, does not belong io the same genus; it has been properly sepa- rated from it by Walckenaer. The last pair of legs is the longest in this, and the eyes differ essentially in their sitnation. ‘There is another species, very com- mon in Carolina, which, however, I have not yet ob- served here, making a web nearly similar to this, but very different in all its generic characters ; “it sught not to be taken for the other: 1 intend pub- lishing a description of the genus Aranea, in which this will form a separate section. But the charac- ters which E have given are sufficient to ascertain whether a spider belongs to the genus Tegeneria, se that with some attention, no mistake w ill occur. , OF AMERICAN SPIDER. 55 _ The species which I am treating of, is of a black colour, inclining to blue; the abdomen is marked with about ten livid pale spots, and a line towards its’ anterior extremity: Lhave seen specimens where the legs were marked with black spots. I think it ne- cessary to remark here, that spiders of the same spe- cies living in dark places, vary greatly in theit co- lonrs, according to the manner in which the light strikes upon them. The great point in this case I think, is to ascertain the genus, for it appears that the web of all s species belonging to it, has the same Virtnes, and this is distinct cota the Aranea Domes- _tica, whose web has been used. in Europe: we see an illustration of this in the genus meloe, where every species possess more or less the blistering power.

As yet but litile attention has been paid to the crystalline forms of the minerals of this’ country, many of which have no analogies with those described by European crystallographers. Among this num- ber may be mentioned a variety of phosphate of lime, with the description of which, I have now the honor to present the Academy,’ and hope to continue the 36 ON SOME NEW FORMS research by the examination of some others in my possession. {.

In this case the two opposite faces of the prism M offer square surfaces at the same time that the faces P P, and four of the faces of the hexaedral prism are linear. Besides these two varieties there occurs in the same matrix, crystals of the primitive form, varying from one tenth of an inch to an inch; as well as in rounded pieces. Indeed nearly. all the crystals present some of their edges rounded, and particularly the margins _ of the summits, so that they often have the appearance | of hexaedral prisms terminated by rounded summits. CRYSTALS OF ZIRCON. i OE The phosphate of lime is slowly soluble in nitric acid ; and occasions no phosphorescence when its powder is thrown on burning coals. It is found at St. Anthony’s nose, near New York, in magnetic pyrites of a grey, sometimes bronze yel- low color. This ore is partly ina state of decompo- sition, having then the appearance of the brown oxide of iron, the crystals which occur in this part of the gangue have their edges generally blunted, which is not the case with those found in the un- altered pyrites; this would induce the belief that these crystals have been partly dissolved by the sul- phuric acid formed by the decomposition of the py- rites. The crystals found in that part have always a ferruginous color, while those in the undecomposed part of the ore, are of a blackish green color. This mineral, besides phosphate of lime, contains lamel- lar hornblende of a dark green, when in the unde- composed ore, and of a ferruginous color in the de- composed parts. ZL CON.

In the form of the mandibles it resembles Nymphon and Ammothcea but the want of palpi distinguishes it from those genera, its pro- per situation is probably next to the genus Phoxichi- lus. It, unquestionably, is generically the same with Phalangium aculeatum of Montague, (Trans. Lin. Soc. vol. 9, tab. 5,) which Dr. Leach, in the article Crustaceology of Brewster’s Encyclopedia, refers to the genus Nymphon, but which, as far as I can dis- cover, he has omitted in his subsequent works.

He considered it to be an Hydrate of the OF IRON OF NEW JERSEY. 83 Protoxide of Tron, The means which the Judge used were insufficient to shew the existence of Phos- phoric acid, which is one of its essential constituents. For a description of this mineral the reader is referred to the above work, and to the mineralogy of Professor Cleaveland. This mineral was analysed as an hydrated proto- phosphate of Iron, a preliminary examination having shewn that it contained no other substances, A. 5 Grammes of the mineral were dissolved in nitro-muriatic acid with heat. Water was then added to dilute the liquor, and the iron was thrown down by ammonia, in union with the phosphoric acid ; the precipitate separated from the liquor by filtering was washed and calcined: the resulting liquor was set by for future examination, B. In order to decompose the ferruginous phos- phate, it was treated with three times its weight of caustic potash, at a red heat, in a silver crucible, the mixture was constantly stirred and maintained at that temperature for half an hour ; after cooling, it was diluted with water and filtered. As one fusion does not always free the oxide of iron from phosporic acid, it was again fused with another portion of that alkali, again diluted and filtered. The oxide of iron was well washed with water acidulated with acetic acid, to separate it from the potash, then dried and cal- eimed, It weighed 2.42 grammes. As the iron in 84 ON THE BLUE PHOSPHATE this mineral is in the minimum state of oxidation, the difference being eight per cent. the real quantity con- tained in it will be 2.227 grammes of Protoxide. C. To the liqnor, from which the oxide of iron had been separated, nitric acid in excess was added, and boiled to expel the carbonic acid that might have united with the potash during its fusion, &c. .Am- monia was then added in excess which gave a slight precipitate having the appearance of alumine. it weighed, after calcination, 0.02 gramme D. The above liquor by the addition of muriate of lime gave an abundant precipitate of phosphate of . lime which separated as usual by filtering and being calcined weighed 2.60 grammes. E. Supposing that the ammonia in the liquor A had decomposed a part of the phosphate of iron, it Was examined as in © and D; thus treated it gave 0.21 gramme of phosphate of lime, making together 2.81 grammes ; as this salt is composed of 54 parts of base, and 46 parts of acid, the quantity of phos- phoric acid will be 1.2926 grammes. F. To ascertain the quantity of water contained in this mineral, 5 Grammes were dissolved in nitric acid evaporated to dryness, and calcined to expel all the nitric acid. This was repeated a second time, to be certain that all the protoxide of iron was converted OF IRON OF NEW JERSEY. 85 into peroxide. It weighed 3.78 grammes: as no other volatile matter exists in the blue iron earth but water, the quantity of it.ought to equal this loss, (1.22 grammes) and the difference between the protoxide of the mineral and the tritoxide obtained by the ana- lysis, which is 0.193 gramme; together 41.4143 granmes. Hence we have for result, grammes or per ct.

This acid, exposed to a red heat with charcoal in a coated glass tube, gave Phosphorus; henee, no doub{f can-exist as to this mineral being a phosphate of iron. Lately this mineral has been re-examined, with 86 ON SEVERAL NEW SPECIES the assistance of Judge Cooper, in the laboratory of the College of South Carolina, in Columbia, with the same results. Descriptions of several new species of Cutile-fish. Read March 20, 1821. By ©, A. Lesvevr. Having observed many species of the class Ce- phalopoda, and being desirous to arrange them agree- ably to the new systematic distribution of this class, which Dr. Leach has published, (in the Journal de Physique for May, 1818,) I experienced much diffi- culty in disposing of one of my species. ‘This spe- cies corresponds with those of his first erder Octopo- da, by having eight arms, similar to those of the Eledona, &c. and with those of his second order, by the form of the body, and the position of the fin, being similar to those of the species of the Genus Loligo. With these characters a ought to form an antermediate section, between these two orders. Dr. Leach has appropriated the na me _ Ocio- poda to those animals of this class, that have eight arms, and a body destitute of a fin; and the name of Decapoda to such as are furnished with ten arms, and with fins which margin the body (or sac} entirely, or partially. The latter, constituting his second order, are in part referred to a family which he names Sepudea and which is composed of the Genera Sepia and OF CUTTLE FISH. Sy Lohgo of Lam, and he places the latter after the ‘Sepia. ) But the characters which he assigns to this family, do not appear to me to harmonize with those of the genus Sepia of Lamark, of which the body is oval, short, sub-cbtuse, furnished with fins throughout its whole length; sustained by a very distinct, thick, sub-obiuse bone, which is sometimes armed with a spime posteriorly, is hard and solid towards the back, tender and cellular beneath, and is “ composed of calcareous, very thin, parallel lamina, connected together by thousands of very smail, hollow columns, which are perpendicular to their surfaces, (Cuv. Regne Animal.) Are not these last characters suf- ficient te distinguish and to separate entirely the genus Sepia from that of Loligo? inasmuch as this latter genus, on the contrary, has a body enclosed in a sheath, which is long, cylindrical, subulate, nar- row, with the fins terminal, united or separate; a very thin, feeble bone, which is often narrow, trans- parent, sometimes partially gelatinous; this bone or cartillage, which belongs also to the Sepiola, appears to me to present a character which ought to approxi- mate the Loligos to the Sepiola, as Mr. Cuvier has done, (Regne Animal, t. 2, p. 364,) and which will not admit of the interposition of the genus Sepia, as in the arrangement of Dr. Leach. It may then be proper to establish a distinct family for the reception of the genus Sepia, to be distin- guished by the name given to it by Dr. Leach, of 8s - ON SEVERAL NEW SPECIES Sepiidea, with the characters which Mr. Cuvier has assigned to the genus (Regne Animal, p. 365.) For there is good reason to believe, that when the species of the Mediterranean and the other seas, shall be more critically examined, that many species will be discovered, that will require new divisions to be made in this family, as well as in the present genus Loligo. It may also be proper to consider the Loligos as forming a separate family. It is of little consequence what characters we select for the distribution of these animals into families and genera, if our arrangement is the most convenient, and exhibits, as near as pos- sible, a gradual transition from one to the other. The order in which Mr. Cuvier arranged them is- very natural, he places the Polypus of Aristotle, the Eledona, the Loligo and the Sepia in succession 3 and the new genus which I shall propose in this essay, may be readily intercallated in the series. If we observe the form of the body; that of the fins, and their position; the form and the number of — the arms; the disposition, the number, and the form of the suckers, their corneous circles either entire or divided, their detentations; the arms svhich haye these suckers regularly or irregularly armed ; in fine, those which have nails, either naked or covered by " amembrane, upon the longer arms; and those which have nails and suckers; together with the form of the bone; we shall then have characters sufficient for the formation of new divisions. OF CUTTLE FISH. 89 A careful examination of all the species which | exist in the cabinets, and which, from the general form of the body, are regarded as the same, would _ prove that many distinct kinds have been associated under one specific denomination. Thus I regarded the species described in this paper, from the collection of the academy, and that from the Philadelphia Museum, as specifically the same, with one of which I made a drawing at Sandy- bay ; but upon comparing them with each other, they all proved distinct. In the following arrangement I have considered the form of the body, ie: number of the arms and their armature. To the family L apply the name of Lolhigoidea, of which the genera may be divided into those which have not long arms; and those which * have long arms, and finally, those which have simple nails; those which have nails and suckers; and those which have suckers only. ramity LOLIGOIDEA Cuaracters.—Body enclosed in a sac, which is elongated, narrow, cylindrical, subulate posteriorly ; fins terminal, united or separate; bone very thin, more or less transparent, sometimes partially gelati- nous; arms as in the Sepia, with or without long arms. * Arms sub-equal. cENus (st, LEACHIA.

The sac is solid, firm, cylindrical, sda at- tenuated to a point, and furnished with a flat appen- dice anteriorly ; fin terminal, more than half as long as the body, united in a point posteriorly, lateral angles rounded, lateral and posterior sides thickened, anterior side thin, surface with transverse strie, formed by small muscles; head small, compressed, with a small transverse membrane each side below the eyes; neck small, short; eyes covered by a mem- OF CUTTLE FISH. 93 brane; arms eight, of which six are subtriangular, the two superior ones a little shorter than the second pair, which are equal to the inferior pair, third pair very strong, rounded, and depressed, longer than the others, furnished with a membrane at their exterior part; all the arms furnished with two series of suck- ers, which are hemispherical, alternate and. peduncu- lated; the disks are bliquely truncated, most ele- vated on the exterior side, beneath indented for the attachment of the conic peduncle, they are armed with six horny brown teeth above, of which two su- perior ones are narrow and pointed, and the four others broader ; inferiorly and upon the narrow side of the disk is a long, horny, brown lamina; the two long arms, are subcylindric, dilated at their extre- miiy, margined on each side by an undulated mem- brane, upon which the peduncles of the suckers re- pose; four series of suckers, of which the middle series are largest, and terminated at each extremity by smaller suckers; disks hemispheric, transversely truncated, armed with a corneous circle, and having strong remote teeth, with two or three smaller inter- vening ones, in the central disks; but I have not been able to determine the number of intermediate teeth in the lateral disks; besides the thin lateral membrane, . 1ere is another thicker one, placed ob- liquely upon the enlarged extremity of the long arms; the opening of the mouth, has three concen. tric folds, the exterior one of which is furnished with a much folded membrane, which is terminated 94 ON SEVERAL NEW SPECIES by six small appendices, or false arms, furnished | with several suckers at their extremities, the two in- feriour appendices shorter. The bone is broad, naviculiform, terminated in a point at each extremity, thin at the margin, carina- ted, and a little more robust at the anterior extremi- ty, which is narrowest. The superior part of the head, of the teutacula and of the back covered with reddish-brown points, which are less numerous upon the sides and abdomen. Coast of South Carolina ? When Mr. Maclure and myself were at Sandy Bay in 1816, we saw a great number of Loligos col- lected by the fishermen, and held in reserve as bait for Cod-fish, which they catch in great numbers on the banks of Newfoundland. The beautiful color with which they were ornamented, induced me to take a drawing of one immediately, but not then hay-_ ing leisure to completeit, I took a specimen with me to finish the drawing at my leisure. But recently — upon comparing this specimen with my drawing, I was much surprized to perceive that I had brough; with me a very distinct species from that which [had observed. I mention this circumstance to explain the cause of the brevity of the following description, taken from my drawing. OF CUTTLE FISH 95 8. Loxtco *illecebrosa. The body of this species is rather short, narrow, subequal anteriorly, terminated acutely posteriorly ; fins approximated at their origin, terminated in a point, and taken together rhombiform ; the two longer arms are narrow, dilated at their extremity, and furnished with two series of suckers, the eight arms are almost equal and provided throughout their whole length with two ranges of suc- kers; the arms are long, and with the head they mea- sure two-thirds of the length of the sac; the bone is very narrow in the middle, dilated at each extremity, and terminated at the inferiortiy by a hollow invert- ed cone. . Colors vivid and beautiful, passing from a brilliant red to a deep and clear blue, upon the back, the head, arms, tail, and fin, which are covered with deeper points of the same color, the under part of the body is paler, region of the eyes finely tinted with yellow. This species is known by the name of Squid at Sandy Bay, and is made use of by the fishermen as bait in the Cod-fishery. 4 Loxico *Bartlingu. Lateral arms compres- _ sed, and with the inferiorpair, furnished with a membrane upon all their exterior length. This species for which we are indebted to captain Bartling, who obtained it in the Gulf Stream, forms part of the collection of the Academy. It differs from the preceding by its arms, which are generally longer, filiform at the extremity; a broad, thin and 96 ON SEVERAL NEW SPECIES softer fin is situated at the superior part of the tail; its body also is larger. ‘i he bone presents a still greater difference, in being very much compres- sed at the base, and a little dilated at the opposite extremity. Color, deep blackish brown; the four superior arms being very much compressed, have their inte- rior surface very narrow and destitute of a lateral membrane ; the suckers are very small and crowded, and seem to form but a single range, though in reali- ty they are disposed in two series and are alternate; the eight arms are furnished with suckers through- out all their length, and are unequal, the inferior ones being longest, and the others diminishing gradu- ally. The long arms, the extremities of which had been cut off by the fishermen, appear to have been very long; suckers hemispheric, placed upon a short peduncle; corneous ring, broad and mutic; the body is inserted very deep in the sac, which renders it very free at the superior part; eyes free in their orbit, which is dilated, rounded, destitute of nictita- ting membrane, and furnished with a lachrymal emargination anteriorly; budy, back and tail co- vered with reddish brown points; a slightly depres- sed line on the superior part of the sac. 5. L. *Pavo. Sac much elongated, rounded ; eyes very large; arms very short, depressed; fin cordate, terminated in a point; bone very narrow anteriorly, somewhat dilated posteriorly, and subge- latinous. OF CUTTLE FISH. 97 ‘This species is remarkable by its elongated, point- ed, and very soft sac; by its bone, which is sub-equal in its greater length anteriorly, and enlarged towards the base, where it is terminated in an obtuse point. The fins are united and oblong-cordate, entire at base, and spreading from the sac, which is narrow, smooth, and, as well as the head and arms, covered on every part with very large ocellations, which are connected together by smaller intermediate ones. General colour, deep carmine-brown; head small; eyes large, prominent, and directed more forward than laterally; neck narrow, short; arms very short, furnished with two series of suckers, supported by narrow pedicles, which are fixed upon the margin at the base of the membrane and towards the narrow- est side of the sucker, which is truncated very ob- liquely, the larger side being exterior, and the nar- rower interior; they are also distant from each other; the arms are destitute of lateral interior membranes; the large arms are thin. I have not been able to ascertain whether this spe- cies is armed with hooks er suckers. The tips of the small arms, as well as the greater portion of the larger arms, had been cut off by the fishermen; an operation which they perform upon all they capture, for fear of receiving injury from them. _ Length of the sac 10 inches. The figure repre- sents the animal half its natural size; it was a female, the oviduct of which was exserted and pendant, as represented in the plates itis an aggregation ef small, 13 98 ON SEVERAL NEW SPECIES white globules, attached and sustained by a men? brane.

O. *Carribea.—Arms eight, unequal; tentacula two, elongated, and armed near their extremity with suckers, and with corneous hooks, concealed, each in a membranous sac; fin truncated. Inhabits, amongst fuci, in the Gulf of Mexico, and in the Gulf Stream. Head rounded, short, crowned by eight arms and two tentacula; eyes large, lateral, and but little pro- minent, pupils black, iris blue; body enclosed in a sack, cylindric anteriorly, conic posteriorly, and terminated at this extremity by a sub-triangular fin, of which the inferior angle is truncated and rounded; the space between the origins of the wing which forms this fin is 2 lines long; their extent from one angle to the other, is 8 lines, their length is 6 lines; the diameter of the sack anteriorly 6 lines, The eight arms are, in all their length, each fur- nished with two series of suckers; the two superior arms are the shortest, being only 10 lines in length; the six others are 9 lines long; the tentacule are one inch and an half long, and are armed at their ex- tremity with two series of incurved hooks, which al- ternate with suckers at their bases; the series of suck- OF CUTTLE FISH. 99 ers extend further towards the head, than those of the hooks. These curved horny nails are each cover- ed by a membrane when at rest, which resembles a small pocket. ‘he inferior arms are furnished with a small longitudinal natatory membrane upon their - exterior side, and at their base; the lateral arms have also a membrane towards their extremity and above. Colour, as usual in the species of this family, vary- ing from a blue to a purple, or yellow, &c. Total length from the extremity of the tentacule to the tip of the fin, 3 inches. Head 5 lines; tentacule 4 inch and an half; body 4 inch. OxssEeRvATIONS.—I have had for some time in my possession, a drawing ef a Loligo, which was obtain- ed during a voyage from the Canary Islands to the Isle of France, in latitude 36° 40’ south, and longi- tude 29° east. This drawing, which was executed by Mr. Petit, is very finely coloured; but as it is not sufficiently detailed, it was regarded as inadequate to establish the certainty of the existence of the species » which it represented. All doubts, however, are now dissipated by our observations upon the species of the Gulf Stream, and by those recently published by Dr. Leach upon a species of the coast of Africa. Although Mr. Petit’s drawing is not calculated to exhibit minute characteristics, yet the following dif- ferential traiis are remarkable. ‘The hooks are but slightly curved, and destitute of suckers at their base, the fin is rhombvidal, prolonged to a point at the 400 ON SEVERAL NEW SPECIES extremity. "To this species 1 have applied the name | of O. Angulatus. It has eight unequal tentacula, the two superior ones shortest. ‘Fotal length from the ex- tremity of the tentaculz to the tip of the fin, 10 inches; body 5 inches; head very small, 8 lines long; the two superior tentacula 4 inch and 9 lines; the long tenta- cula 5. inches. Serious cardioptera. Peron. Peron has left no description of this species, which we saw in latitude 31° south, and longitude 48° east; the species appeared to belong to the genus Sepiola, and perhaps even to the unguiculated ones. The habit of living in many seas, amongst the fucus which floats upon the surface of the waters, is similar to that of the Gulf Stream, which is furnished with horny nails upon the long arms, as described above. ees OxnseRVATIONS.—I subjoin the names of the spe- cies that Peron and myself observed in New Hol- jJand, in order to note their existence. I have sent de- scriptions of them to France. Peron designated them by the followmg names: 1. Srepra sepiola. Peron. Very small. Inhabits the coast of, Endrach, in New Holland. As this species does not appear to be the sepiola of Lin. I propose for at the name of minima, as it is very small. ' OF CUTTLE BISH. 104 Family of Seriepea. Leach. 2. Serra octopa. Peron. Very small. Inhabits the island of Dorre, Shark Bay. This species can hardly be the octopus of Lin. I propose, therefore, the name of Peronii for it. 3. Sepia rugosa. Bosc.—1 do not think that our species is the same with that described by Bosc; I therefore propose for it the name of that naturalist, Boscii. 4. Sepra varietas. Peron. Inhabits the small island of Dorre. The shores of King’s island were covered with Sepiz, many of which were living. We there obser- ved also many. groups of their eggs. REFERENCE TO THE PLATES.

While Mr William Maclure and myself were passing the islands of the Antilles, we had occasion to observe two species of fish, appertaining to the new genus Hemiramphus of Cuvier.

A. 3Grammes of the pure mineral, finely pulver- ized, were exposed to a red heat; after the calcina- tion, the powder was of a brownish red colour, and it weighed 2.97 grammes; then the diminution ef 140 _ ANALYSIS OF weight amounts to 0. 03 grammes; but as the Deut- oxide of Iron, contained in the mineral must have absorbed 0.008 grammes of oxygen, in passing to the state of peroxide, the luss due to water, there- fore, amounts to 0. 038 grammes on 3 grammes, or 1. 266 per 100. B. The calcined mineral (A.) was heated to red- ness in a silver crucible, during 30 minutes, with 9 grammes of caustic potash; the mixture on cooling assumed a pale green colour; it was treated with wa- ter, to which it likewise communicated a greenish hue ; this indicated a trace of manganese. Muriatic acid, in excess, was added to it, the solution was complete and of a yellow colour; it was then evapo- rated toa dry gelatinous mass, then treated with water, acidulated with muriatic acid, and again mo- derately evaporated; more water was then added, and it was filtered; on the filter there remained S¢- lex, which, after being washed and calcined, weigh- ed 1.565 grammes on 3 grammes, or 52. 166 per 100. ©. The filtered liquor (B.) was neutralized with caustic potish, when treated with the hydro-sulphate of potash, it yielded a black precipitate ; this precip- itate was well washed und calcined, in a porcelain vessel, to expel the greater part of the sulphur; it was then treated with a small portion of nitric acid, and exposed to a strong red heat, in a platina crucible. ‘The Alumine and per-oxide of iron, thus obtained, weighed 0.45 grammes; they were treated repeatedly with caustic potash, until the Alumine was completely separated, the per-oxide of iron then AMERICAN MINERALS. 141i weighed 0. 33 grammes; as the mineral is of a black- ish colour and magnetic, the iron exists in the state of a Deutoxide, and the 0. 33 grammes of per-oxide are equivalent to 0. 322 grammes of Peutoxide on 3 grammes, or 10.733 per 100. Then, by difference, we have Alumine 0. 12 grammes on 3 grs. or 4 per 100. D. The liquor (C.) when treated with the oxalate of potash, gave rise to an abundant precipitate, which when washed and exposed to a high temperature, yielded Lime 0. 60 grammes, on 3 grammes, or 20 per 100. EK. After the separation of the lime, the liquor (D.) when treated with caustic potash, produced a preci- pitate of magnesia, which being washed and strong- ly calcined, weighed 0.54 grammes on 3 grammes, or 11. 323 per 100.

Of a Ferruginous Oxydulated Copper Ore. This ore occurs in Lebanon County, Pennsylva- nia, accompanied by oxydulated Iron ore ; occasion- ally by minute portions of pyrites, and is frequently incrusted with green carbonate of copper. Its co- lour, both in the massive and pulverulent state, is redish brown. It possesses little or no lustre. O- paque. Amorphous. Fracture, irregular. Frag- ments, indeterminate. Strongly magnetic. ‘The specific gravity of a piece containing some slight traces of carbonate, was 4. 554. Analysis. A. 5 Grammes, of the pulverized ore, were expo- sed to ared heat, and it was stirred in order to allow the copper and iron to pass to the state of per- oxydes. After the calcination, the powder was black, and the loss of weight was 0.10 grammes; but the quantity of oxygen absorbed by the deutoxide of iron and the protoxide of copper, was found by calculation to amount to 0. 249 grammes ; therefore, the loss in water amounts to 0. 349 grammes, on 4 grammes, or 6. 98 per 100. ' _ B. The calcined ore (A.) was boiled with nitro- muriatic acid, to which it soon imparted a deep green colour, when the argilaceous residue appeared flaky and colourless ; the solution was evaporated to dry- ness, to expel the excess of acid, the residue of a green colour, was treated with water, and the solu- tion was filtered: the argil remaining on the filter, AMERICAN MINERALS. 143 when washed and calcined, weighed 0. 19 grammes on 5 grammes, or 3.80 per 100. C. The liquor (B.) was treated with an excess of ammonia, an abundant precipitate was formed, part of which was immediately re-dissolved by the am- monia, and communicated to it a beautiful dark blue colour, the residue appeared red, and afier 24 hours digestion it was separated from the ammoniacal li- quor by filteration, when washed and exposed to red heat, it weighed 2.16 grammes. A _ portion of this precipitate was re-dissolved in muriatic acid, and treated with an excess of ammonia, the copper was thus found to have been completely separated. Ano- ther portion was fused with caustic potash, but hay- ing obtained no mineral cameleon, it was ascertain- ed that the ore contained no manganese. Therefore, the 2. 16 grammes were pure per-oxide of iron, but as the mineral was magnetic, the iron must be esti- mated in the state of a deutoxide, and the 2. 16 grammes of tritoxide are equivalent to 2. 108 gram- mes of deutoxide, on 5 grammes, or 42. 16 per 100. D. The ammoniacal liquor .(C.) was boiled to drive off the greater part of the excess of alcali, a slight excess of sulphuric acid was then added to it and a polished bar of iron, was allowed to remain in it, until the liquor, when tested with sulphurated hy- drogen, was found to contain no more copper. ‘The metallic copper thus precipitated, when well washed and expeditiously dried, weighed 1.95 grammes, but from the colour of the ore, the copper must be considered to exist in the state of a protoxide, and the 1.95 grammes of metallic copper, are equivalent 144 ANALYSIS OF to 2 194 grammes of protoxide, of copper on 5 grammes, or 43. 83 per 100.

A. 5 grammes underwent no alteration from the action of heat. B. 5 grammes treated with nitric acid, yielded an entire and colourless svlution.

The liquor (B.) after the separation of the lime, was evaporated to perfect dryness; towards the close of the evaporation, the matter became black, owing to the decomposition of the oxalic acid; when the entire decomposition of the acid was supposed. to have been effected, the resi:tue was treated with water, and the liquor, after being filtered, was treat- ed with ammoniac, which occasioned a colourless precipitate of phosphate of lime ; this being a portion of the mineral, that resisted decomposition by the oxalic acid, it weighed 0.29 grammes on 5 gram- mes, or 5. 80 per 100.

By Larpner VANvuxem. “‘ The substratum of the soil of Columbia (S. C.} and its vicinity, consists of Granite, the kind which is commonly considered to be primeval. This rock commences at Richmond in Virginia, and is visible to this place in most of the rivers and streams which cross the main road between these two towns. It is the only primitive rock known to exist east of this road. Its usual colour is grey, sometimes it presents very beautiful red varieties as on the Saluda river. “ AMERICAN MINERALS. 447 fi is very barren in extraneous minerals; no marks of stratification appear in it, but itis every where di- vided by cracks and fissures breaking it up into irre- gular masses, of no great extent; very often it is traversed by small veins, of an extremely fine grained granite, of a light flesh or pink colour. Like most gra- nite, itis snacapubne of decomposition, and varies very considerably in different parts of the same mass, whether expesed to the surface, or covered with ve- getable or other soil; thus along the lower canal of the Saluda, whole fields of it are in a decomposed state, here and there presenting among its ruins some masses, which from unknown causes have escaped uninjured. As commonly observed of this rock, it presents large masses rounded upen the surface, ascribable either to the progress of decomposition which commences with the angles and edges or as some have supposed to a species of concretionary ar- rangement of its minerals, during its consolidation. Last year my attention was attracted by two pa- rallel black veins in a mass of granite, occurring by the side of Rocky branch,* just below Dr. Fishers milldam. The surface of the rock protrudes but a little above the ground. These veins lie near to each other, of from one to two inches in thickness, nearly vertical in their position, and of an unknown length aud depth. The substance of these veins scarcely * A small creek passing within a few hundred yards of the South Eastern boundary of Columbia, and emptying inte the Congaree. 148 ANNALYSIS OF adheres to the granite, and breaks with ease into ir- regular fragments, whose sides are slightly changed or soiled, as we so often observe in the trap rocks. In the other fracture, the rock is extremely tough, presenting a very fine scaly texture, of a bluish black _ colour, opaque, excepting on the edges of the frag- ments, and enveloping as a base, numerous small im- perfect crystals, of a dark green colour: sometimes also, though rarely, fragments of granite are also con- tained in it. By exposure to the air, the basis be- comes of a light dirty olive green colour, whilst the crystals assume an ochery appearance. Examined, whenin minute fragments,with a powerful microscope, it presents a confused mass of silvery particles. I was not able to ascertain with this instrument, if it con- sisted of more than one mineral species. It feebly attracts the magnet. Before the blowpipe, it fuses into a black globule, whuse fragmeuts, when viewed by transmitted light, are of a dark green colour. As a part of the rock, which encloses these veins, has lately been removed by blasting, I collected a consi- derable quantity of their substance, and on breaking it, I succeeded in obtaining some perfect crystals of the dark green substance above mentioned, which on examination, proved to be Pyrozene, or augite, pre- senting the well known form the triunitaire of Hauy, so abundant in the lavas of Auvergne, Italy, Sicily, &c. ‘ihe hemitrope or macle of the same form also exists in it. These veins appear to be almost entirely com- AMERICAN MINERALS. 449 posed of Pyroxene, more or less confusedly crystal- lised, and varying considerably in the size of its crys- taline particles. It is probable that there is an in- termixture of a small quantity of Feldspar, from the difference of colour, which the perceptible and imperceptible particles exhibit when ina state of de- composition. From the general character of these veins, their total dissimilarity with all rocks of the class to which the granite belongs, from their being composed of Pyroxene and of the triwnitaire form so common in almost all lavas, I think in the present state of our knowledge, (as to the origin of rocks,) that we are in some measure authorized in consider- ing them to be of Volcanic, rather than of Neptunian origin.” Descriptions of Univalve shells of the United States. By Tuomas Say. The terrestrial and fluviatile shells which form the subject of the following pages, were chiefly ob- tained on the late expedition to the Rocky Moun- tains, under the command of Major Stephen H. Long. They are now deposited in the Phiiadelphia Museum, and constitute, in the collection of that in- stitution, a distinct arrangement. A few descriptions are added to this essay, of shells discovered in East Florida, Alabama, Penn- sylvania, and New-York. 150 UNIVALVE SHELLS Type and Class. MOLLUSCA GASTEROPODA. Genus Heurx. : + Umbilicus none ; labrum reflected. 1. H. *multilineata. Shell thin, convex, imper- forated ; of a brown colour, with numerous dark-red revolving lines, which are minutely and irregularly undulated ; whorls six, with elevated, subequidistant lines, forming grooves between them ; aperture luna- ted, not angulated at the base of the column, but obtusely curved; labrum contracting the mouth slightly, reflected, white, more or less distinctly stained by the termination of the spiral red lines, and adpressed to the body whorl near the base; umbili- cus covered with a white callus.

ANIMAL granulated; granule large, whitish, in- terstices blackish ; foot beneath black. An exceedingly numerous species in the moist fo- rests on the margin of the Mississippi near the Ohio, and the Missouri as far as Council Bluff. The red revolving lines are numerous, varying from four or five to twenty-five or thirty and perhaps still more; they are sometimes confluent into bands; when viewed within the mouth, they appear sanguineous. OF THE UNITED STATES. 451 2, H. *appressa. Sheil depressed, brownish horn colour; whorls five, depressed, forming an angle on the external one, more acute near the superior angle of the labrum, with numerous transverse, elevated, equidistant lines, with interstitial grooves; umbili- cus covered over with calcareous matter, but con- - cave within; aperture moderate; labrum dilated, reflected, white, margined with brownish; near the base, appressed to the body whorl, and covering the umbilicus ; a slight projecting dentiform angle on the inner middle; labrum with a strong, prominent, ob- lique, compressed, white tooth, which gradually slopes and becomes obsolete towards the umbilicus. Var. a. Labrum with two projecting angles. Breadth, three-fifths of an inch. AnimaL—foot pale; neck above and each side blackish. Inhabits the banks of the Ohio and Missouri. This species is very common on the banks of the Ohio below Galiopolis: I also found it near Council Bluff. 1t very much resembles H. tridentata, but the umbilicus is covered over; the outer lip at base is flattened upon the shell; and there is but a single angle upon it. In Lister’s conch. pl, 93, fig. 93, is the representation of a shell, which is most probably intended for this species. Lister’s figure is quoted in the books, for H. punctata, but as the figure of a different species (Born mus. pl. 14, fig. 17 and 18) 452 UNIVALVE SHELLS is also referred to as the same, I conclide that two distinct species have been confounded together under the common name of punctata; certainly the charac- ter from which this name was taken, is never present on our shell. Specimens have been subsequently found by Dr. Thomas M‘Kuen, near the Falls of Niagara. 3. H.* palliata. Shell depressed, with elevated lines, forming grooves between them; epidermis fus- cous, rugose with very numerous minute tubercu- lous acute prominences; volutions five, depressed above, beneath rounded, forming an obtuse angle exteriorly, which is more acute near the termination of the labrum; wmbzilicus covered with a white cal- lous ; aperture contracted by the labrum; labrum re- flected widely, white, two profound, obtuse, sinusses on the inner side above the middle, forming a promi- nent distinct tooth between them, and a projecting an- gle near the middle of the lip; labium with a large, prominent, white teoth, placed perpendicularly to tie whorl, and obliquely to the axis of the shell, and nearly attaining the umbilical callus. Inhabits Hlinois. Length of the column 7-20 of an inch. Greatest breadth, four-fifths of an inch. Var. a. A very prominent acute carina; destitute of minute prominences. Inhabits Ohio. Breadth nearly 1 inch. OF THE UNITED STATES. 153 This shell is found on the banks of the Mississip- pi in moist places. It verymuch resembles H. triden- tata but is destitute of umbilicus, has a rugose epider- mis, and ismuch larger. Itisstillmore closely allied fo appressus but its superior magnitude, teeth and epidermal vesture, distinguish it from that species, Specimens have subsequently been found by Dr. Thomas M‘Kuen near the falls of Niagara. 4. H. *inflecta. Spire convex; volutions five; wrinkled across; suture not profoundly impressed ; aperture strait; labrum reflected, bidentate, teeth se- parated by a profound sinus, the superior teeth in- flected, behind the lip a profound groove, which ab- rubtly contracts the aperture in that part, so that although the lip is reflected, yet its edge is not more prominent than the general exterior surface of the body whorl, at base the lip is adpressed and covers the umbilicus ; labrum with a large prominent ob- lique lamelliform tooth; umbilicus closed. Greatest transverse diameter nearly 9-20 of an inch. Inhabits Lower Missouri. The teeth of the labrum somewhat resemble those of tridentata ; but in the form of the groove behind the labrum, and the pillar tooth, it resembles H. hir- suta, several specimens were found, but all dead shells, and destitute of their epidermis. 20 154 UNIVALVE SHELLS 5. H. *clausa. Shell fragile, slightly perforated, subglobular, yellowish horn-colour, above convex; whorls four or five; aperture slightly contracted by the lip; lip reflected, flat, white, nearly covering the umbilicus.

A small and handsome species, which somewhat resembles albolabris, but is much smaller, more rounded, and is sub-umbilicate. This shell also oc- curs though perhaps rarely in Pennsylvania. 6. H. *obstricta. Shell depressed, with elevated lines forming grooves between them; epidermis pale brownish, naked; volutions five, depressed above, beneath rounded, with an acute projecting carina; umbilicus covered with a white callus, indented ; mouth resembling that of H. palliata. Tnhabits Ohio. Breadth nearly one inch. This species is very closely allied to Hehax pal- liata, but the epidermis is not covered with small ele- vations as in that shell, and the carina is very pro- minent and remarkable. 7. H. *elevatq. Shell pale horn colour, spire elevated; whirls seven, regularly rounded; umbilicus OF THE UNITED STATES. 455 none; aperture somewhat angulated; labrum dilated, reflected, pure white, at base adpressed to the body whirl, abruptly narrowed on the inner edge beneath the middle, and continuing thus narrowed to the su- perior termination, leaving a projecting angle behind the middle; labium with a large, robust, very ob- lique, sub-arquated, pure white tooth. Greatest breadth, 7-8 of aninch. Column, 9-16. Found rather common in the vicinity of Cincinnati, Ohio, it seems to be distantly related to thyroidus, by the tooth on the labium, but this tooth is much more robust; it differs more essentially by the much more elevated spire, and by the superior half of the dilated lip being abruptly narrowed so as to form a prominent angle near the middle. Itis also a much thicker shell. tt Unbilicus closed ; labrum simple. 8. H. *interna. Shell yellowish-red; volutions six or eight; whorls with regular, equidistant, ele- vated, obtuse lines across them separated by regular grooves; lines obsolete beneath; spire convex, little elevated; aperture very strait, transverse less than one half of the longitudinal diameter; labrum not re- flected; within, upon the side of the labrum, two pro- minent lamelliform teeth, of which the superior one is largest, and neither of them attain the edge of the lip; region of the base of the columella much in- dented; umbilicus obsolete or wanting. 156 UNIVALVE SHELLS Transverse diameter more than 3-10. Height ofthe columella above 3-20. Inhabits Lower Missouri. Of two specimens which I obtained, the larger one had six volutions, and the smaller one had eight; the superior tooth in the larger was concave towards the base of the shell. tis a remarkable and very dis- tinct species. 9.

A large variety of this species, is found very eommon on the Missouri, of the length of about 4-5 i64 UNIVALVE SHELLS of an inch. Iobserved one specimen, which was upwards of an inch long. Genus PLANORBIS. 4. P. *armigerus. Shell dextral, brownish-horz colour, wrinkles obsolete 5 spire perfectly regular, slightly concave; suture well impressed ; umbilicus profound, exhibiting the volutions; whorls four, longer than wide, obtusely carinated above, carina obsolete near the aperture, a carina beneath conti- nued to the aperture; aperlure longitudinally sub- obovate, oblique; labrum blackish on the edge ; throat armed with five teeth, placed two upon the pillar side, of which one is large, prominent, per- pendicular,lamelliform, cblique, and rounded abrupt- ly at each extremity; near the anterior tip, Is & small prominent conic acute one ; on the side of the. labrum, is a prominent lamelliform tooth near the base, and two slightly elevated, oblique, lamelliforn ones above. Length, 1-4 of an inch nearly. Inhabits Upper Missouri. Remarkable by the teeth; but these are only dis- coverable by the microscopical examinatiou of the mouth, and they are situated far within it. P. trivelvis b carn ‘tus and parvus inhabit ponds of water, in the vicinity of Council Bluff. 2. P. *parallellus. Shell dextral, with very mi- ante transverse wrinkles, and regular, revolving, = OF THE UNITED STATES. A63 equidistant, parallel, slightly elevated lines; spire a little convex ; volutions four; aperture longer thaw wide ; umbilicus exhibiting all the volutions. Breadth, less than 3-20 of an inch. Inhabits Upper Missouri. This shell has evidently the habit of a Helix, and may probably belong more properly to that genus, but having found it only ina dried up pond, in com- pany with a vast number of aquatic shells, I refer it for the present to this genus. 8. P. *exacuous. Dextral, depressed, with an acute edge. Inhabits Lake Champlain. Cabinet of the Academy. Shell depressed; whorls four, striated across, wider than long, not elevated above the suture, but a little flattened, sides obliquely descending to an acute lateral ede, below the middle ; spire not impressed; suture not profoundly indented; beneath, body whirl flattened, on the inner edge rounded; umbilicus re- gular, extibiting all the volutions to the apex ; aper- ture transversely sub-triangular ; labrum angulated in the middle, arquated near its inferior tip, the su- perior termination just including the acute edge of the penultimate whorl. Greatest Breadth, rather less than 1-4 of an ero This species was found in Lake Champlain by Mr. Augustus Jessup, who deposited it in the col- lection of the Academy. Only two specimens ec- 166 UNIVALVE SHELLS curred. It may be readily distinguished from P. parvus, by its more convex form above, the spire not being impressed, and by its very acute lateral edge. It appears to be pretty closely allied to Pla- norbis nitidus of Europe, but it is larger, the umbili- cus much more dilated, and the aperture does not embrace the penultimate whorl so profoundly. 4. P. *campanula tus Sinistral; whorls longer than wide; aperture sub-campanulate. Inhabits Cayuga Lake. Cabinet of the Academy. Shell sinistral, not depressed ; whorls four, slightly striate across, longer than wide; spire hardly con- cave, often plane; body whirl abruptly dilated near the aperture, and not longer behind the dilatation than the penultimate whirl; suture indented, well defined to the tip, the summits of the volutions being rounded; aperture dilated; throat narrow abruptly; umbilicus profound, the view extending by a mi- nute foramen to the apex. Greatest length of the body whorl, 1-4 of an inch. Breadth from tip of the labrum, 1-2 inch; at right angles to the last; 2-5 inch. This shell abounds in some of the small streams, which discharge into Cayuga lake, where it was collected by Mr. Jessup, who presented specimens to the Academy, and to me. Itis readily distin- guished from our other species, by the sudden dila- ~- OF THE UNITED STATES. 169 tation of the outer whirl, near the aperture in the adult shell, forming a large oval chamber. The sum- mit of the outer whirl, behind the dilated portion, is not, or hardly elevated above the summits of the _ other volutions. Genus Lymneus. 1. L. *elongatus. Shell horn colour, tinged with reddish-brown; spire elongated, tapering, acute; whirls six or seven, slightly convex, wrinkled across; body whirl, measured at the back, more than half the total length; suture moderately indented ; aperture less than half the length of the shell; labiwm with ealcareous deposit. Length, one inch and three-tenths. inhabits in considerable numbers, the ponds and tranquil waters of the Upper Missouri. It is very distinct from L. catascopium, by the much greater proportional length of the spire. 2. Lymneus columellus. (Jour. Acad. Nat. Sci- iences, vol. ]. p. 14.) Var. a. Small, black—from Cold water creek of the Missouri. This is most probably a distinct species, we obtained but a single specimen of it. 3. L. *reflecus. Shell fragile, very much elon- gated, narrow, honey-yellow, tinctured with brown- ish, translucent, slightly reflected from the middle; volutions six, oblique, wrinkled transversely-; spire more than one and an half times the length of the 468 UNIVALVE SHELLS aperture, acute, two or three terminal whirls vitre- ous: body whirl very little dilated; aperture rather narrow: labrum with a pale margin, and dusky red or blackish sub-margin. Inhabits Lakes Erie and Superior. Total length, 13-10—of the aperture 11-20 of an inch. This shell is remarkable for its narrow and elon- gated form, and for the consequent, very oblique re- yolution of its whirls. Vi hen viewed in profile, it has a slightly reflected appearance. It was kindly sent to me for examination by my friends Messrs. S. - B. Collins and D. H. Barnes of New York, and was found in Lake Superior by Mr. Schoolcraft. 1 re- collect to have seen a specimen two or three years since brought from Lake Erie, by James Griffiths. It is proportionally longer than elongatus. 4. L. *appressus. Shell elongated ventricose ; volu- tions six; spire regularly attenuated to an acute tip, rather shorter than the aperture; body whirl dilated, proportionally large; aperture ample; columella with the sinus of the fold profound, callus perfectly appressed upon the shell, to the base. Inhabits Lake ‘Superior. This shell exhibits very much the appearance of L. stagnalis, but its body whirl is less proportionally dilated. The callus of the labrum is perfectly ap- pressed to the surface of the whorl even to the base, exactly as in stagnalis. I have seen but a single weathered and broken specimen, which was sent me OF THE UNITED STATES, 169 for examination by my friends Messrs. Collins and Barnes, of New York. It was found in Lake Supe- rior, by Mr Schoolcraft. Since writing the above, Mr. Jessup presented me with several specimens, which he collected in Ca- nandaigua and Cayuga lakes. 5. L. *elodes, Shell oblong conic, gradually acu- minated, reticulate with transverse lines and longitu- dinal wrinkles; whirls rather more than six; spire acutely terminated; sutwre moderately impressed ; aperture shorter than the spire ; labrum, inner sub- margin reddish obscure ; labium, calcareous deposit rather copious, not appressed at base, but leaving a linear umbilical aperture; body whirl on the back longer than the spire. Inhabits Canandaigua Lake. Var. a. Whirls simply wrinkled across, the cal- careous deposit at base, appressed to the surface of the whirl. } This species was found by Mr. A. Jessup ; it bears the most striking resemblance to L. palustris. The variety was found by the same enterprising mineralogist at Morristown, New-Jersey. I have subsequently received specimens from Mr. S. B. Collins, of New-York, who procured them in a marsh near the Saratoga springs. 6. L. *desidiosus. Shell oblong sub-conic ; whirls five, very convex, the fourth and fifth very small, the second rather large; suture deeply indented ; aper- ture equal to or rather longer than the spire; la- 170 UNIVALYE SHELLS bium, calcareous deposit copious, not perfectly ap- pressed at base, but leaving a very smal! umbilical aperture. Inhabits Cayuga Lake. Length 7-20 of an inch. Found by Mr. Augustus Jessup. It is closely allied to E. elodes, but the whirls are more convex, one less in number, and the two terminal ones are proportionally smaller; the callus of the labium, also, near its inferior termination, is applied still more closely to the surface of the body whirl. 7. L. *macrostomus. Shell sub-oval; whirls five, body whirl somewhat reticulated; suéwre not pro- foundly indented; spire about two-thirds of the length of the aperture, acute ; aperture much dilated ; labrum not thickened on the inner sub-margin. Inhabits Cayuga Lake. Length one half of an inch, and upwards. Imperfect specimens of this shell were found on the shore of Cayuga Lake by Mr. A. Jessup, but they are sufficiently entire, tuexhibit considerable similari- ty to some varieties of L. auricularius of Europe. It may readily be distinguished from L. catascopium, by its much more dilated aperture. 8. L. *emarginatus. Shell rather thin, translu- cent; volutions four, very convex ; bedy whirl large; suture deeply impressed; spire somewhat eroded ; mouth two-thirds of the length of the shell. Length nearly 4-5 of an inch; of the mouth half inch. OF THE UNITED STATES» 171 Inhabits Lakes of Maine. This species was discovered by Mr. Aaron Stone. It is a rather larger, and considerably wider shell than L. catascopiwm, and the emargination visible on a profile view of the umbilical groove, is far more profound. Genus Puysa. 1. P. *gyrina. Shell heterostrophe, oblong; whirls five or six, gradually acuminating to an acute apex ; suture slightly impressed ; aperture more than one half, but less than two-thirds of the length of the shell; labrum a little thickened on the inner margin. Length rather less than one inch. Inhabits waters of the Missouri. Of this species, I found two specimens at Bowyer creek, near Council Bluff. It differs from P. hete- rostropha in magnitude, in having a more elon- gated spire, and less deeply impressed suture. 2. P. *elongata. Shell heterostrophe, pale yel- lowish, very fragile, diaphanous, oblong; whirls six or seven; spire tapering, acute at the tip: suture slightly impressed; aperture not dilated, attenuated above, about half as long as the shell; columella much narrowed near the base, so that the view, may be partially extended from the base towards the apex. Inhabits shores of Illinois. ~ Length 7-10 inch. Greatest breadth 3-10 nearly. 172 UNIVALVE SHELLS Anima deep black, immaculate, above and be- neath; tentaeula setaceous, a white annulation at base. in the fragility, of the shell, this species ap- proaches nearest to columella. It is very common in stagnant ponds on the banks of the Mississippi. When the shell includes the animal, it appears of a deep black colour, with an obsolete testaceous spot near the base on the anterior side. Its proportions are somewhat similar to those of P. hypnorum. P. heterostropha (Nicholson’s Encyc.) Is very com- mon in ponds of the Missouri as far as Council Bluff. Genus CyciostToma, €. *marginata. Shell turreted, pale hora colour, or dusky, obsoletely wrinkled across; suture rather deeply impressed; volutions six; aperture mutic, sub-oval, truncated transversely above by the penul- timate whirls, nearly 1-3 the length of the shell; labium nearly transverse, colour of the exterior part of the shell; labrum equally and widely reflected, thick, white ; wmbilicus distinct. Inhabits Upper Missouri. Length 1-5 of an inch. | Size of Paludina lapidaria. Lister represents a species on plate 22 fig. 19, which, although rather larger, may possibly be intended for this species ; he - OF THE UNITED STATES. 173 denominates it “ Buccinum exiguum Rufum quing orbium.” This shell does not perfectly correspond. in character with Cyclostoma ; it is most probably a Pupa, and if so the specific name must be changed, as the present name is pre-occupied in that genus. Genus VALVATA. V. tricarinata (Nicholson’s Encyc.) occurs in considerable numbers in ponds, in the vicinity of Council Bluff. Genus PALuDINA. 1. P. *ponderosa. Shell somewhat ventricose, much thickened, olivaceous or blackish; spire not much elongated, much shorter than the aperture, eroded at tip, but not truncated ; whirls five, slightly wrinkled across ; suture profoundly impressedi; aper= ture sub-ovate, more than half the length of theshell ; Jabium with much calcareous deposit, and thickened into a callosity at the superior angle; within tinged with blue. Inhabits Ohio River. Greatest length one inch and 11-20. Transverse diameter one inch and 1-10. This shell is common at the falls of the Ohio, and is a very remarkably thick and ponderous species. It bears a striking resemblance to P. decisa, and has without doubt, been generally considered as the same ; but it differs from that species in being much more 174 UNIVALVE SHELLS incrassated and heavy ; and although much decorti- cated and eroded upon the spire, the tip is not trun- cated. In the labrum also is a distinctive character ; by comparison this part will be perceived to be less arquated in its superior limb, than the corresponding part in decisa. 2. P. *integra. Shell olivaceous, pale, conic ; whirls six, wrinkled across ; spire rather elongated, entire at the apex; suture profoundly indented ; aperture sub-ovate, less than half of the length of the shell. Inhabits the waters of the Missouri. Length 1-4 inch. Very much resembles P. decisa, the spire how- ever is more elongated, and never truncated at the apex, but always: acute. 3. P. *porata. ‘Shell obtusely-conic or subglo- bose; volutions four, convex, obsoletely wrinkled across; spire obtuse; labrum and labium equally rounded, meeting above in a sub-acute angle; the upper edge of the latter appressed to the preceding whirl; wmbilicus very distinct. Inhabits Cayuga Lake. Cabinet of the Academy. This species which was found by Mr. Jessup, is rather larger and more globose than P. limosa to which it is allied, and has a more distinct umbilicus. It resembles P. decipiens of Ferrussac, but is much less acute, and rather smaller. 3 OF THE UNITED STATES. 476 4. P. *lustrica. Shell conic; whwls slightly wrinkled, convex: sufure profoundly indented; aper- ture oval nearly orbicular ; labrum with the superior edge not appressed to the preceding whirl, but sim- ply touching it; wmbilicus rather large, rounded. Length less than 1-10 of an inch. Cabinet of the Academy. The smallest species I have seen.. The aperture somewhat resembles that of a Valvata, to which ge- nus it may probably be referrible. Mr, Jessup ob- tained two specimens, on the shore of Cayuga Lake. Genus MELANIA. 1. M. *canaliculata. Shell tapering, born-colour ; volutions about seven, slightly wrinkled; spire to- wards the apex much eroded, whitish; body with a large obtuse groove, which is obsolete upon the whirls of the spire, in consequence of the revolution of the suture on its inferior margin; this arrange- ment permits the superior margin of thegroove, only, to be seen on the spire, in the form of an obtuse ca- rina on each of the volutions; aperture bluish-white within, with one or two obsolete revolving sangui- neous lines; labrum slightly undulated by the groove, and with a distinct sinus at the base of the columella. Inhabits Ohio River. Length one inch and one tenth. Breadth 3-5 of an inch. _ Greatest transverse diameter more than 2-5, 476 UNIVALVE SHELLS Very common at the Falls of the Ohio River. Tt - is probably the largest_species of this genus in the United States, and may be readily distinguished from its congeners by its broad groove. 2. M. *elevata. Shell gradually attenuating to the apex, slightly and irregularly wrinkled, oliva- ceous ; suture not deeply impressed ; volutions nine or ten, with several more or less elevated revolving lines, of which one being more conspicuous gives the shell a carinated appearance; aperture oblique, equalling the length of the second, third, and fourth ~ yolutions conjunctly. Length one inch. Breadth two-fifths. Tnhabits Ohio River. Distinct from our other species, by the elevated re- volving lines. 3. M. *conica. Shell conic, rapidly attenuating to an acute apex, very slightly wrinkled, olivaceous ; suture not deeply impressed; velutions seven or eight; aperture oblique, equalling the length of the second, third, and fourth whirls conjunctly. Var. a, With from one to three, revolving, rufus or blackish lines. Length nearly 3-5 inch. Of the aperture 1-4 inch. TInhabits Ohio River. May be readily distinguished from 4. virginica OF THE UNITED STATES. 177 by the much more rapid attenuation of the spire, and in the proportional difference in the length of the aperture, which in the virginica is not more than equal to the length of the second and third whirls. 4. M. *prerosa. Shell subglobular, oval, horn colour; volutions three or four, wrinkled across; spire very short, much eroded, in the old shell, so much so as to be sometimes not prominent above the body whirl, body whirl large, ventricese, with a very obtuse, slightly impressed revolving band; aperture suboval, above acute and effuse; within on the side of the exterior lip about four revolving purplish lines, sometimes dotted, sometimes obsolete or wanting; tabium thickened, particularly at the superior termi- nation near the angle, and tinged with purplish ; base of the columella somewhat elongated and in- curved, meeting the exterior lip at an angie. Length about 4-5.inch. Inhabits Ohio River. Found in plenty at the falls of the Ohio, the spire is remarkably carious in the older shells, and the penultimate whirl, between the aperture and the spire is also remarkably ereded in many older shells. The spire in the young shell is entire, and but little prominent though acute, and the bands are distinct on the exterior of the shell. This shell does not seem to correspond with the genus to which L have for the present referred it, and owing to the configuration of the base of the columella, if itis nota Melanopsis, 23 178 UNIVALVE SHELLS it is probable its station will be between the genera Melania and Acathina. 1 propose for it the generic name of ANCULOSA. 5. M. *armigera. Shelltapering, brownish-horr colour; volutions about six, slightly wrinkled ; spire near the apex eroded, whitish; body whirl with a revolving series of about five or six distant, promi- nent tubercles, which become obsolete on the spire, and are concealed by the revolution of the succeeding whirls, in consequence of which arrangement there is the appearance of a second, smaller, and more ob- tuse subsutural series of tubercles on the body whirl; two or three obsolete revolving reddish-brown lines ; aperture bluish-white within 5 a distinct sinus at the base of the columella. TInhabits Ohio River. Length about one inch. Distinguished from other N. American species, by the armature of tubercles. GENUS BULLA. B. fluviatilis. Shell sub-oval, pellucid, pale yel- lowish white, finely wrinkled; volutions three ; body whirl large with a prominently carinated shoulder bounding the spire; spire perfectly flat or slightly concave, giving to the shell.a perfectly truncated ap- pearance in that part; aperture longer than the co- lumella, oblong-ovate, extending beyond the tip of the spire; umbilicus profound, edged by a slight carina, OF THE UNITED STATES. 479 Length of the aperture 1 5 of an inch. Greatest breadth somewhat less. Inhabits the River Delaware. This species seems te be rather rare; it was dis- covered by Mr. Aaron Stone, deeply imbedded im the mud; Mr. William Hyde of this city, has since found specimens of it, amongst some dead shells of other genera assembled in a small inlet of the river.

Description and Analysis of the Table Spar, from the vicinity of Willsborough, Lake Champlam. By Larpner VanuxemM. Read March 5, 1822. This mineral, which by some was considered to be Ichthyopthalmite, and by others Grammatite, ap- pears in masses, composed of imperfectly tabular crystals, irregularly grouped together, of a white colour, and presenting a slight pearly lustre in al- most every direction in which it is viewed. ‘The crystals present natural joints, parallel toa quadran- gular prism, with a rhombic base, whose angles are about 94 and 86°; other cleavages again divide this prism according to the diagonals of its base; all the joints are easily separated with a knife, and all of these apparently presenting the same degree of smoothness and lustre: no joints are perceptible in the direction of the base. Itis fusible inte a transparent TABLE SPAR. 183 colourless glass. Hardness between common glass and carbonate of lime. Specific gravity 2. 89. Ac- companying this mineral are small grains.of cocce- lite, whose colour is brown and green; the former ones, no doubt belong to Garnet, the latter, from pos- sessing natural joints, seems to be a distinct sub- stance. The mineral in question, forms a jelly with muri- atic acid: loses nothing by calcination, although maintained for half an hour at a red heat: on ex- amination, I found it to consist of Silex, of Lime, and a small quantity of oxide of Iron. Its analysis was made in the following manner. 150 grains were boiled with muriatic acid, as long as any part appeared to be unattacked; water was then added and the solutionfiltered, the Silex an in- soluble part when calcined, weighed 77 1-2 grains. That no uncertainty should exist with respect to the quantity of Silex, it was a second time repeated upon another portion of the mineral, with precisely the same result. To the liquor from which the Silex had been se- parated, carbonate of ammonia was added until it ceased to give any further precipitate; this was se- parated by filtering, when well dried, it weighed 424 grains; and consisted of carbonate of lime, slightly coloured with oxide of Iron. It was set aside for further examination. The ammoniacel liqnor was evaporated to dryness, then calcined; nothing remained but 4:1-2.grains of muriate of Lime, which had escaped decomposition. 484 ANALYSSIS OF Sulphuric acid was added to the Carbonate of Lime, which converted it into Gypsum and dissolved the Iron mixed with it. It was filtered and the Iron so held in solution, was thrown down by ammonia thus separated and calcined, it weighed 2 grains. The result of this Analysis, gives us on estimating the quantity of lime by difference, Silex - - 77. 5 or percent. 61. 67 Lime - heey (1 Mes, - - 47. 00 Oxide of Iron - 2.0 - “ - 1. 35 100.

By Avueustus E. Jessup. Read March 19, 1822. On the eastern, and a considerable part of the west- ern shore of Lake Champlain, as far north as Bur- lington in Vermont, shell Limestone is the only rock that appears; hence, I am induced to believe, that the bed of the lake rests on the Secondary or Fletz formation. ‘This rock extends in some places four and five miles from the lake on the eastern side, but is seldom found to extend more than a few paces from its western shore: it abounds with fossil reliquie ; such as Terebratulites, Encrinites, Orthoceratites, and Corallines. Its colour is generally biuish-gray. To the west, it appears to rest on the Primitive, and IT think, also tothe east. My reasons for supposing it to rest on the primitive, on the Vermont shore of the lake, are the following: 1st. That many of those minerals which occur in the vicinity of the western shore of the lake, are also found imbedded in the same rocks near the eastern shore. 2nd. Near Crown Point in New-York, are very extensive beds of magnetic oxide of iron, ana the same variety is also found north-east of this, near Vergennes in Ver- &?d 186 GEOLOGY, &c. OF A mont. I think that the Transition, does not inter- pose between the Primitive and Secondary forma- tions in this vicinity; or, if it does, but partially so. The hills in the vicinity of Lakes George and Cham- plain, extend in a line nearly north and south; they consist of detached masses, the tops of which are either rounded, er extend nearly in a horizontal line of greater or less extent; their sides are generally very abrupt; their height varies from five to fifteen hun- dred feet above the level of the adjacent lakes. At Essex in New-York, the hiils of Lake Cham- plain, retire from its western shore, about six miles ; their usual height at this place, is about eight hun- dred feet. Nine miles north-west of Essex, in the town of Willsborough is a detached mountain mass, which extends from east to west: on its northern face, near its base; is a bed of Garnet-resinite, in pri- mitive Trap: the bed is from six to ten feet in width ; it extends from South-east, to North-west, and dips towards the North-east, making an angle of inclination with the horizon, of about thirty-five degrees. ‘The Garnet resinite is accompanied by Tabular Spar, common massive, and granular Gar- net, and Pyroxene. ‘This locality was first visited in 1810, by Doct. William Meade ; by whose direc- tions | was enabled to find it. The Garnet resinite is also found imbedded in primitive Trap, at Char- lotte, in Vermont, eight miles east of Essex. Three miles south of the upper falls of Lake George, is an abrupt acclivity, the eastern face of which, presents a surface composed apparently of PART OF NEW YORK. 187 an entire rock, destitute of herbage, and constituting about three-fourths of the whole height of the moun- tain; which I suppose to be about twelve hundred feet. ‘The foot of this rock terminates abruptly at the margin of the lake, and extends along its shore for more than half a mile: it is commonly known by the name of Roger’s Rock. Near the northern ex- tremity of this reck, a spur sets out towards the east, which is apparently about two-thirds as high as the main body of the mountain: it is on this spur, that the following minerals occur either in veins, or im- bedded in primitive Trap, Sienite, or Carbonate of Lime; viz, Augite; Coccolite (Pyroxene-granuli- forme of Hauy); Sphene; granular and massive Garnet; and Plumbago. The primitive Trap is well characterised, the Hornblende being in distinct crystalline laminz, not unlike that which occurs in many places in the vicini- ty of Philadelphia, particularly at the head of the old canal road, on the Schuylkill, and onthe Brandy- wine, near Wilmington. The rock which I have called Sienite, is composed of Hornbleude, and com- pact Feldspar; it therefore differs from the common Sienite in as much, as the Feldspar does not possess a crystalline structure: the colour of the Hornblende is black, and greenish-black, that of the Feldspar is white and reddish-white, or flesh coloured: the pro- portion of the Hornblende is very small: this is the most abundant rock in the neighbourhood of this part of lake George. 188 GEOLOGY, &c. OF A The Carbonate of Lime is white; its structure is coarse-grained, crystalline: the grains, which are generally about the size of a pea, after having been exposed to the action of the atmosphere, for a consi- derable length of time, are easily separated between the fingers. In one place I saw a bed of reddish- brown Serpentine, throughout which small specks of Bronzite were thickly interspersed; it was ap- parently situated in Sienite. It was impossible to ascertain the order of the strata; they appear to dip, towards the north-east and north, and were much interrupted and broken. Garnet Resinite. - This mineral, constitutes almostthe whole of the large bed in the primitive Trap at Willsborough, mentioned in the preceding Geological sketch ;_ its colour in the mass, is brownish-black and reddish- brown; by transmitted light, byacinth-red, inclining to crimson ; by exposure to the air, many specimens, become beautifully iridescent ; external lustre, semi- metallic ; internal, resinous : translucent: form, inde- terminable: fracture, slightly conchoidal: structure, coarse, and fine grained, and compacts grains feebly adhering.

Tabular Spar. This is found interspersed in small beds, in the bed of Garnet resinite, with which it is more or less intimately mixed. Colour, pure and greyish-white ; by exposure to the air, it becomes more opaque, than When first taken from the bed; lustre, pearly: the tables are semi-transparent: it occurs in tables con- fasedly intermixed ; a few of which have a tendency to the hexagonal form; this was noticed by Karsten in some of the European specimens of this mineral : the tables are longitudinally striated. It possesses a double cleavage, parallel to the sides of a slightly rhomboidal prism, its angles by the common gonio- meter are 93° and 87°; longitudinal fracture fibrous; transverse, uneven: scratches glass: moderately frangible: structure, crystalline: specific gravity 2.98. Phosphoresces by friction and heat. Augite. First Variety. This accompanies the Garnet resinite and Tabu- lar Spar, among which it is sparingly interspersed, in grains, of about the size of a small pin’s head. As the term, Coccolite, has been applied to granular Pyroxene, it is probable, that this mineral ought to be classed under that name. Its colour in the grains is emerald green, in powder, greenish white: exter- 490 GEOLOGY OF A nal lustre, dull; internal, glistening: semi-transpa- rent: scratches glass: cleavage, distinct. Augite Second Variety. This variety occurs at Roger’s Rock, near Ticon- deroga, associated with Feldspar, crystallized Sphene, and Plumbago. Colour of the mass, light blackish-green, by long exposure to the atmosphere, it becomes dark blackish-green; colour of the pow- der, greenish-white ; lustre, dull: opaque, in mass * in thin fragments, slightly translucent: form, regu- lar, octagonal prisms, generally without distinct ter- minal faces: I have one specimen on which there are two terminated crystals; but [ do not know that the form is described: it is an octagonal prism termi- nated by four faces, two of which correspond with the two principal faces of the Pyroxene sexoctagone of the Abbe Hauy ; the two other faces may be con- sidered as the result of a decrement upon the edges, formed by the junction of the third terminal face of the sexoctagone with the two principal ones above named: its cleavage, is imperfect: transverse and longitudinal fracture, splintery : fragments, angular: seratches glass: tough: structure, crystalline: the crystals vary from a few lines, to near three inches in diameter. Specific Gravity, 2. 33. Coccolite, (Pyrowene granuliforme of Hauy.) The geological position of this, is the same, as the preceding mineral; of which (both from its physical PART OF NEW YORK. 491, and chemical characters.) it may be considered as be- ing only avariety. ‘The south face of the bluff near Roger’s rock, presents an entire mass, which is com- posed principally of this mineral; its height is about fifty feet, and length eighty. Colour, light blackish-green, and black: lustre, generally feeble, sometimes resinous: semi-transpa- rent: fracture in mass, fine grained: scratches glass : structure, granular: the grains, which are small; in some specimens, adhere firmly, in others, feebly. It is accompanied by Sphene, Garnet, Carbonate of Lime, and Feldspar. Sphene. This accompanies the Pyroxene and Coccolite. Tits colour is reddish and yellowish-brown: lustre resplendent: nearly transparent: crystalline: form dioctaedre of Hauy: that which occurs with the coccolite has no regular form. Granular Garnet. This accompanies the Coccolite ; and is also found in large masses unmixed with any other mineral: Ii has been called by some mineralogists, red Coc- colite. Its colour is red, of various shades: grains small. and feebly adhering. Massive Garnet. This is found in large masses: it passes into the preceding variety. f The Publishing Commitiee have great pleasure in acknowledging the very valuable donation lately re- ceived by the Academy from their president, Wil- liam Maclure, Esq. This donation includes many very rare, costly and splendid works on Natural History, which in addi- tion to those previously in the possession of the Aca- demy, many of which have likewise been presented by Mr. Maclure, constitute one of the most valuable and extensive Libraries of Natural History in the United States. The succeeding catalogue includes a part only of Mr. Maclure’s recent donation, the publication of the remainder is unavoidably postponed for the present. It will appear at the end of the volume, together with a list of donations to the Museum. 222. CATALOGUE OF THE LIBRARY OF THE ACADEMY OF NATURAL SCIENCES, (Continued from vol. Ist, page 493.)
